This machine is a small cleaning equipment, which is mainly composed of cleaning room, shot blasting assembly, elevator, separator, electrical system and other parts. See Figure 1 (Table 1 indicates the name corresponding to the serial number of each part)

Working principle: Add a specified number of workpieces in the cleaning room. After the machine is started, the high-speed projectiles thrown by the shot blaster form a stream of shots, which evenly strike the surface of the workpiece to achieve the purpose of cleaning and strengthening. The thrown projectiles and sand particles flow into the elevator and are lifted by the elevator to the separator for separation. The dust is sucked by the fan and sent to the dust collector to be filtered. The clean air is discharged into the atmosphere. The dust on the cloth bag is mechanically shaken and falls into the dust box at the bottom of the dust collector. The user can clean it regularly. The waste sand flows out from the waste pipe. Can be reused. The shot-sand mixture is retracted into the chamber by the recycling pipe, and reused after the separator is separated. The clean shots enter the shot blasting device through the electromagnetic supply gate to throw the workpiece.

The foundation construction is as shown in the foundation drawing (Figure 2). After the user configures the concrete according to the local soil quality, and uses a level to check the horizontal and vertical level of the plane,

It can be installed and the bolts of each foot are tightened;

1. Before the machine leaves the factory, the cleaning room, shot blasting device and other parts have been assembled into one body. When the whole machine is installed, as shown in Figure 1, tighten the serial number 2 hoist with the hoist on the cleaning room with bolts. When installing the bucket elevator, pay attention to adjusting the bearing seat of the upper driving pulley to keep it level to avoid belt deviation.

2. Install the manual pill gate (No. 6) and the pill supply gate (No. 7) on the separator, connect all the pipelines according to the dust removal system diagram, and the separated waste users can bring their own waste barrels for processing;

3. The installation diagram of the separator is shown in Figure 3. When the separator is working normally, there should be no gaps in the projectile flow curtain. If a full curtain cannot be formed, the serial number 1 heavy hammer should be adjusted until a full curtain is formed. If the separation effect of pellets and sand is not good, you can adjust the separation grade plate (No. 2, No. 3) to get a good separation effect. After the pellets have been screened, the bulk materials should be removed regularly;

4. The hoist belt is connected by the user with holes, and the connection form is as follows:

1. Before the test operation, you must be familiar with the relevant regulations in the instruction manual, and have a comprehensive understanding of the structure and performance of the equipment;

2. Before starting the machine, check whether the fasteners are loose and whether the lubrication of the machine meets the requirements;

3. The machine is required to be assembled correctly, and each component and motor should be tested for single action before starting up. The rotation direction of each motor should be correct, and the belt of the hoist should be moderately tight, without deviation.

4. Check whether the no-load current, bearing temperature rise, reducer, and shot blasting volume of each motor are running normally. If problems are found, the cause should be found out and adjusted;

5. After there is no problem with the single-acting equipment, the dust collector, hoist, and shot blaster can be started in sequence for dry running test, and the dry running time is one hour.

(1) Operation of the machine:

1. Only if you have a comprehensive understanding of the working principle, performance, operation method, lubrication and other aspects of this machine, you can operate it;

2. Put the projectiles (200kg) into the chamber one after another, then put them into the workpiece, close the feeding door, and prepare to drive;

3. Start the dust collector fan;

4. Start by pressing the buttons in turn: hoist, shot blasting device, and shot supply gate to start cleaning. After the cleaning is completed, turn off the buttons in turn: the pill supply gate, shot blasting device, elevator, dust collector fan, and then start the rapping motor to clean the dust, and the rapping will stop after a certain period of time;

5. After the shot blasting machine is completely stopped, open the feeding door and lift the tooling and workpiece out.

6. In case of emergency, press the emergency stop button and the machine will stop working immediately;

7. After all work is completed, the dust collector should be turned off in time;

8. In the ventilation and dust removal system, there are two butterfly valves (see the dust removal system diagram). Adjust the two butterfly valves according to the situation to get a good separation effect;

9. Adjustment of the directional sleeve of the shot blaster:

The adjustment of the directional sleeve can refer to the schematic diagram shown in Figure 4.

10. The shot blasting machine has three types of ejection speeds. When the ejection speed needs to be changed, it can be completed by changing the belt pulley of the shot blasting machine motor. The replacement steps are as follows:

First, turn off the shot blasting device and the main power supply. After the shot blasting device is completely stopped, loosen the motor fastening bolts, remove the V-belt, and then use a hexagonal wrench to loosen the pulley fastening bolts, and use three M12 bolts to tighten the cone The shaft sleeve is separated from the belt pulley, and the belt pulley is removed. Fit the required pulley with the tapered bushing, press it into the motor shaft, and then tighten the three M10 pulley fastening bolts with a hex wrench. Put on the V-belt again, and finally, push the motor to a suitable position with a jack wire, and tighten the bolts to fasten the motor. Note: The outer end surface of the motor pulley should be on the same plane as the outer end surface of the shot blaster pulley. Otherwise, loosen the three M10 pulley fastening bolts for adjustment.

The three projecting speeds correspond to the lifting capacity of the two hoists, and the installation and adjustment methods of the hoist motor sprocket are the same as above.
