It has the following advantages:

Efficiency: With the special shot blasting wheel structure, when the shot speed is 60-72m/s, the shot blasting efficiency can reach 15kg/min·kw.

The blades are quickly assembled and disassembled: because the blades of the shot blasting machine are inserted from the center of the impeller, and the blades are fixed by centrifugal force during the rotation of the impeller, so no clamping tools are required. When disassembling the blades, just lightly tap the outer end of the blades The blades can then be easily removed. It only takes 5-10 minutes to disassemble 8 blades, and the wear of the shot wheel and the orientation sleeve can be checked at the same time.

The holes of the fixed shaft and the directional sleeve on the cover are processed at one time, so that the gap between the directional sleeve and the shot separation wheel can be uniform, which not only reduces the wear of the shot separation wheel to the projectile and the cracking of the directional sleeve phenomenon, but also greatly improved the shot blasting efficiency.

The shape and position tolerance accuracy of the long slots and holes for fixing 8 blades on the impeller body of the shot blasting machine is quite strict. Using the imported special machining center, the indexing-rough milling-finish milling on the impeller can be done in one clamping, Indexing-drilling-reaming-reaming and other processes are completed at one time, which ensures the balance of the operation of the shot blasting machine and makes the balance force distance between 12-15N mm (national standard 18.6N mm). Equipment noise is greatly reduced.

The blades, blasting wheel and directional sleeve of this shot blasting machine are made of Swiss +GF+ DISA company with advanced production technology and high-chromium wear-resistant materials, so that the weight difference of the blades is controlled within 2 grams and the service life is long.

The entire screw shaft is integrally processed after welding, thus ensuring the coaxiality of both ends of the screw shaft. The screw conveyor conveys the shot collected in the bottom hopper to the bucket elevator. This part is an important part of the projectile circulation system of the equipment. The spiral blade is made of alloy material, and its inner and outer circles are stretched after being processed by a special process. The pitch and outer circle dimensions are very accurate, which improves the life of the spiral and reduces the running noise.

The bucket elevator is composed of a direct-connected geared motor, upper and lower rollers, a conveyor belt, a hopper, a closed cover, an anti-reverse mechanism, and a tensioning device.

The feed port of the bucket elevator is connected with the screw conveyor, and its discharge port is connected with the separator.

The hoist cover adopts a bent and welded structure. The lower cover of the hoist is equipped with an inspection door, which can repair and replace the hoisting hopper. Open the door cover on the lower casing to maintain the lower transmission and troubleshoot. The machine is driven by a flat belt. When working, the hopper fixed on the conveyor belt scrapes up the shot material at the bottom of the elevator, and then, driven by the power of the elevator, sends the shot material to the top of the elevator, and finally falls by centrifugal gravity, and the shot material is input Pill sand separator.

In order to ensure that the conveyor belt does not slip during work, the roller is made into a squirrel cage type, which not only improves the friction between the lifting belt and the pulley, avoids the slipping phenomenon of the old-fashioned light belt pulley, but also reduces the pre-tightening force of the lifting belt. Extends the life of the lifting tape. At the same time, the hoist is equipped with a set of tensioning device. When the belt is loose, the belt can be tightened by adjusting the adjusting bolts on both sides of the upper part of the hoist.

The inside of the separation box 35 is provided with a material distribution funnel 38, a first separation channel 39, and a second separation channel 310. The material funnel 38 corresponds to the outer spiral of the trommel 34 and is arranged to receive the pellets guided by the outer spiral. The outlet of the material distribution funnel 38 is facing the separation port 37, and the first separation channel 39 and the second separation channel 310 are located in the material distribution funnel 38 Below the outlet, its relative material distribution funnel 38 is away from the air inlet 36, and the first separation channel 39 and the second separation channel 310 stretch out the separation box 35 respectively and form the first leakage shot opening 311 and the second leakage shot opening 312, the first separation A first filter plate 313 is provided on the channel 39 near the outlet of the distribution funnel 38 , and a second filter plate 314 is provided on the side of the second separation channel 310 near the outlet of the distribution funnel 38 .

In the above scheme, the flow regulating plate 315 is provided at the outlet of the material distribution funnel 38. This design can adjust the flow of the pellets according to the actual work requirements, so as to further improve the separation efficiency and effect of the pellets.

In the specific design process, there is a deflector 316 at the outlet of the material distribution funnel 38. This design allows the shot to stay at a certain angle of inclination, so as to avoid the agglomeration of the shot and affect the separation effect.

The dust removal system adopts a three-stage dust removal method, and the first-stage dust removal is a suction hood filter, and the final dust removal adopts a pulse filter cartridge for dust removal. Dust emission is less than 50mg/m³ (national standard). The dust collector is an important part of the sand making machine. Equipped with an advanced environmental protection dust collector, it can make the cleaning effect better and faster, and it can also reduce the noise of the equipment to prevent the environment from polluting the atmospheric environment and the working environment.

Because this system deals with metal dust, considering the service efficiency and life of the filter medium, the dust removal system adopts a secondary cyclone settler. Equipped with a cyclone settler, it can effectively settle 70% of the dust in the airflow, greatly reducing the dust concentration in the airflow entering the dust collector, effectively improving the filtration efficiency and prolonging the service life of the system.

LT-9 inclined-mounted filter cartridge dust collector is a new generation of high-efficiency dust collector designed and manufactured by our company by absorbing the environmental protection technology of Donaldson Corporation of the United States.

Under normal operation, the dust-laden air enters the "LT" type dust collector through the bottom inlet of the side compartment, and part of the dust is settled in the ash bin due to gravity, and then disperses upwards and passes through the filter element, and the dust is blocked on the outer surface of the filter element. , the filtered clean air enters the clean air chamber through the center of the filter element and is discharged through the outlet pipe.

Filter elements are automatically and intermittently cleaned in such a way that only one set (2) of filter elements are cleaned off-line at any given time. During the cleaning process of the filter element, the pulse controller connects the power supply of an electromagnetic pulse valve, so that the corresponding membrane valve ejects pulse high-pressure air, and the high-pressure air passes through the filter element from the inside to the outside and will The dust is removed, and the dust particles fall into the dust hopper, and then enter the ash collection bucket. The pressure of compressed air is best adjusted to 6kg/cmP2P, 6kg/cmP2P-7kg/cmP2P compressed air pressure is the most standard setting value that can meet the requirements of the cleaning function. The smaller the set value of the compressed air pressure, the smaller the air consumption of the pulse valve. The pulse jet controller can generally be adjusted to clean a column of filter elements every two minutes, that is, to connect a pulse valve every two minutes. To increase the cleaning energy, the pressure of the compressed air can be increased, but it should not exceed 7kg/cmP2P.

The dust removal box is the core component of the dust removal system, which is made of high-quality plate and national standard steel riveting structure. The whole can be divided into two parts, mainly divided by the drawing board. The upper part is the negative pressure chamber and the lower part is the interception area. When working, the fan starts to make the negative pressure chamber generate a strong negative pressure, and the air in the lower interception chamber flows from the fine fibers of the filter material The dust is sucked into the upper negative pressure chamber through the gap and then discharged into the atmosphere from the chimney through the fan, and some dust is intercepted by the filter material on the outer wall of the filter cartridge. The dust attached to the filter cartridge falls into the ash storage bin to be discharged. The entire drawing board is cut from 10mm cold-rolled steel plate, and the cutting process is processed by an advanced large-scale laser cutting center to ensure that the drawing board has no deformation. Fully ensure the sealing strength of the dust collector.

The main components of the pulse system include controller, signal line, solenoid valve, air bag, nozzle and so on. When working, the controller sends an opening signal to each electromagnetic valve for a certain period of time in the manually preset time to achieve the effect of timing cleaning. The height of the nozzle is accurately calculated and placed by computer CAD simulation test, which replaces the complicated Venturi jet cleaning.

This shot blasting machine is also provided with an inspection platform 6, which is arranged on the side of the body, so that the body can be easily repaired.

When cleaning the workpiece, the hook lifts the workpiece into the blasting area of the shot blasting cleaning room, closes the side door, and starts the dust removal system, separator, hoist, screw conveyor, shot blasting device and shot supply gate in sequence to perform shot blasting cleaning Work, after cleaning, hoist out of the cleaning room for unloading and loading.

The above are only preferred embodiments of the present utility model, and do not limit the utility model in any form. Although the utility model has been disclosed as above with preferred embodiments, it is not intended to limit the utility model. Any Those who are familiar with this profession, without departing from the scope of the technical solution of the present utility model, can use the technical content disclosed above to make some changes or modify equivalent embodiments with equivalent changes, but all without departing from the technical solution of the utility model Any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the utility model still belong to the scope of the technical solution of the utility model.
