This machine is a small cleaning equipment, mainly composed of cleaning room, blast wheel assembly, hoist, separator, electrical system and so on.

Working principle: a specified number of workpieces are added to the cleaning chamber. After the machine is started, the steel abrasive pill thrown at high speed by the blast wheel forms a flow pill, which is evenly struck on the surface of the workpiece, thereby achieving the purpose of cleaning and strengthening. The thrown abrasive pill and sand particles flow into the hoist and are lifted by the hoist into the separator for separation. The dust is sucked into the dust collector by the fan, and the clean air is discharged into the atmosphere. The dust on the bag is mechanically beaten and dropped into the dust box at the bottom of the dust collector. The user can periodically remove the waste sand and flow out from the waste pipe, and can be reused. The shot sand mixture is taken back into the chamber body by the recycling tube, and is reused after separated by the separator, and the clean abrasive pill is passed from the electromagnetic pill supplying gate into blast wheel to shot blast workpiece.

Installation:

According to the local soil quality configuration concrete, check the plane vertical and horizontal level with the spirit level, then you can install it and tighten the bolts around the place;

1. The cleaning chamber and the blast wheels have been assembled into one body before leaving the factory, and the hoist, the hoist on the cleaning chamber is fastened with bolts. When installing the bucket elevator, care should be taken to adjust the upper drive belt pulley bearing block to keep it level so as not to deflect the belt.

2. The manual pill separating gate and the pill supplying gate are installed on the separator, and all the pipelines are connected according to the dust removal system diagram, and the separated waste, user can prepare the waste bucket to deal with by himself;

3. When the separator is working normally, there should be no gap in the flow curtain of the abrasive pill. If the curtain is not formed, the ball breaker of the serial number 1 should be adjusted until the curtain is formed. If the separation effect of the shot pill and sand is not good, the separation grade plate can be adjusted to obtain a good separation effect, and the bulk material after the shot pill sieved should be periodically removed;

4. The hoist belt is connected by the user’s matching hole.

Free running debugging

1. Before the test, you must familiarize yourself with the relevant regulations in the instruction manual and make a comprehensive understanding of the structure and performance of the equipment;

2. Before starting the machine, it is necessary to check whether the fasteners are loose or not, and whether the lubrication of the machine meets the requirements;

3. The machine requires correct assembly, and the single-action test should be carried out for each component and motor before starting. The direction of rotation of each motor should be correct, and the belt of the hoist should be tight and not deflected.

4. It is necessary to check whether the no-load current of each motor, the temperature rise of the bearing, the speed reducer, and the blasting capacity is normal. If the problem is found, the cause should be identified and adjusted.

5. After the single-action equipment has no problem, the dust collector, the hoist and the blast wheel can be started in sequence to perform the free running test, and the idle running time is one hour.

9. Adjustment of the control cage of the blast wheel.

10. The shot blasting machine has three kinds of throwing speeds. When it is necessary to change the throwing speed, it can be done by changing the blast wheel motor belt pulley. The replacement steps are as follows:

First, turn off the blast wheel and the main power supply. After the blast wheel is completely stopped, loosen the motor fastening bolts, remove the V-belt, then use the hex wrench to loosen the pulley fastening bolts and use three M12 bolts to separate the cone axle sleeve from the belt pulley and the pulley is removed. Fit the required pulley to the cone axle sleeve, press it into the motor shaft, and then tighten the three M10 pulley fastening bolts with a hex wrench. Then put on the V-belt. Finally, push the motor to the appropriate position and tighten the bolt to fasten the motor. Note: The outer end of the motor pulley should be on the same plane as the outer end of the blast wheel. Otherwise, loosen the three M10 pulley fastening bolts for adjustment.

The three types of throwing speeds correspond to the lifting amounts of the two types of hoists, and the installation and adjustment methods of the hoisting motor sprocket are the same as above.

11. This machine has a manual pill separating brake. In the normal work, the manual pill separating gate is in the state of opening when pill supplying and closing when the material discharging. At this time, the abrasive pill is supplied to the electromagnetic pill supplying gate. When it is necessary to unload, simply pull the manual pill separating brake handle to the opposite position to discharge. Note that the handle should be fastened to the appropriate position with the fastening bolts, whether it is unloading or pill supplying.

12. After using the machine for one week, the inspection door at the lower part of the front of the chamber should be opened in time to remove the bulk material on the sieve plate, check the wear condition of the sieve plate, and replace the sieve plate in time.
