Especially suitable for small batch parts surface cleaning and strengthening. This machine is the new product development and design of advanced technology at home and abroad, it has good cleaning effect, compact structure, low noise, good cleaning equipment, the main features are: 1.1, the machine adopts the new type of direct efficient shot blasting machine has the advantages of simple structure. Leaves, the replacement is convenient, clean and high efficiency; 1.2, the special wear-resistant rubber track, reduce the workpiece collision damage phenomenon, reducing equipment noise; 1.3, using mechanical tipping bucket automatic feeding, reduce the labor intensity of workers; the workpiece after cleaning, track Automatic unloading unloading conveyor No.9 Huanghai West Road, Dafeng District, Yancheng Ci3ty, Jiangsu Province, China TECHNICAL PROPOSAL to reverse, convenient workpieces; 1.4, the equipment is arranged at the outlet of a belt conveyor, conveyor to transport material laterally disposed of material can be used two frame; 1.5, dust removal device, the exhaust gas generated in the first room all cyclone settling chamber, to realize coarse filtration (for large exhaust gas particles of dust, debris); and then through the pulse Cartirdge filter fine dust; the gas filtered out emissions to avoid working environment damage. III. the structure of the working principle and structure characteristics of machine equipment mainly consists of cleaning room, door, automatic feed hopper, discharge conveyor, turning track, hoisting machine, screw conveyor, separator, pellet feeding system, shot blasting machine, dust collector, electrical systems. The main parts are as follows: 3.1, clean up Department of welding steel structure, in order to make the ejection projectile with effective ejection to the surface cleaning workpiece on the top side of the installation by blasting machine installation to install tilt, shot blasting machine, easy to adjust the ejection angle. The chamber lining for all high chromium alloy plate (except outside), using building blocks type of installation, wear nut, maintenance, convenient replacement; life wear plate is not less than 4000 hours. The door adopts a multi labyrinth seal, ensure the steel will not overflow the door. The door wall adopts the abrasive rubber skin protection, ensure the door The wall is not damaged. 3.2, the workpiece is processed, and open the door, by way of reverse track, the workpiece from the shot blasting chamber to pour in the conveyor, and then transported to the transport frame (the transport frame owned). 3.3, the workpiece blasting, track continuously rotating cycle, driven by the shot blasting chamber workpiece the tumbling movement, the workpiece around can be emitted from the beam cover shot blasting machine, ensure the treatment effect of the No.9 Huanghai West Road, Dafeng District, Yancheng Ci4ty, Jiangsu Province, China TECHNICAL PROPOSAL workpiece surface. The size of the aperture design specifications track, according to the size of the different diameter of the track. The track by driving roller rotate speed reducer. 3.4 hoist: bucket elevator by cycloid reducer, upper and lower roller, conveyor belt, hopper, sealing cover and tensioning device. A bucket inlet is connected with the screw conveyor machine, the outlet is connected with a separator. The cover by folding lifting Bending forming and welding structure. Lifting hood shell is provided with the access door, can repair and replacement of the hopper. Open the cover of the door cover, can repair the lower transmission, eliminate the bottom plug. The projectile machine adopts flat belt rotation. When the hopper is fixed on the conveyor belt will be put up at the bottom of pill material machine the sweep, then drive hoist motor, will be sent to the top of the lifting pellets, finally by centrifugal gravity blanking pill material input separator. In order to ensure the work when the conveyor belt slip, the roller is made into a whole with a pass, which can not only improve the lifting belt and belt friction the force between wheel, avoid the old light belt wheel slippage, and reduces the pretightening force of the lifting belt, prolonging the service life of hoisting belt. At the same time lifting machine is provided with a set of tensioning device. When the belt loose, by adjusting the hoist on both sides of the upper part The adjusting bolt can the belt tensioner. 3.5, screw: screw conveyor is arranged in the room below, will fall down bin collection shot transported to the hoist. The bottom grid plate No.9 Huanghai West Road, Dafeng District, Yancheng Ci5ty, Jiangsu Province, China TECHNICAL PROPOSAL is arranged above the spiral conveyor, the top covered with special alloy wear plates, to protect the body and not xiacang spiral blade shot through. 3.6, for the pill system: how much traffic from the gate opening projectile to control the size of the gap, and the gate opening gap size is controlled by the valve, the structure is stable, reliable, low failure rate. 3.7, the equipment separator: the be separator adopts two grade separation mode of gravity winnowing screening, has good separation effect and high productivity, have a positive effect on improving the service life of blade. The normal operation of the separator, the projectile on the no air filtration should be, if not To form a full curtain, should adjust the partition gap, until the formation of full curtain, in order to get a good separation effect. 3.8, shot blasting machine, shot blasting machine: (q034 II) is mainly composed of a blade, impeller, impeller, directional, shell, the main parts of special motor and other components. The production efficiency is high, a large quantity of shot blasting, low failure rate, low noise, easy maintenance. The shot blasting machine has the following advantages: a), special impeller structure, blasting ratio can reached 17.5kg/min.kw. b) blade assembly and disassembly: because the blade is inserted into the center of the impeller impeller device, fixed blade by centrifugal force in the process the rotation of the impeller, so do not need any clamping tools. Remove the blades, just shot apart, and then tap the outer ends of the vanes and can easily be removed from the center of the impeller blade. Remove the 8 leaves, only 5~10 minutes, and can also check the impeller and To wear a c). The double disc impeller, good stability, projection area concentration, shot No.9 Huanghai West Road, Dafeng District, Yancheng Ci6ty, Jiangsu Province, China TECHNICAL PROPOSAL uniform. d) in the leaves of the impeller, impeller, directional sets, made of special high chromium wear-resistant cast iron material, the leaf weight difference control within 5 grams, greatly reduce the blasting operation when the noise (less than 85dB), prolong the life of wearing parts. e) has the advantages of beautiful appearance, exquisite structure, manufacture and maintenance. The surface quality of the workpiece after shot blasting to satisfy the general standard on the visual and magnetic particle inspection. 3.9, dust removal system in blasting process continuously produce dust, such measures are not taken, will affect the workpiece cleaning quality, and dust pollution escape workshop. The equipment adopts two grade dust catcher, the cyclone body with pulse jet cartridge dust; large particles generated by blasting powder in the state, through a settlement of dust of the cyclone body will The powder particles sank down to avoid the cartridge impact; can prolong the service life of the filter cylinder; the settlement of the cyclone body; the fine dust into the cartridge dust; after cartridge dust filtration, filtered air as gas emissions, but the filtration tank or the sewage, not affect production. Living environment, collection efficiency up to 99.5%. The pulse jet cartridge filter adopts the advanced manufacturing technology design, the filter material filter. Using the new features of the filter dust collector is the ultra-thin fiber adhesion layer of sub micron filter in general, the adhesion layer between No.9 Huanghai West Road, Dafeng District, Yancheng Ci7ty, Jiangsu Province, China TECHNICAL PROPOSAL the fibers arranged very closely, the gap is only the minimum 1%. of the underlying fiber mesh can put most of the sub micron particle barrier on the outer surface of the filtering material, so that it may enter the bottom inside the fiber. Therefore the formation of good ventilation dust layer at the early stage, the The low resistance, high efficiency.
