DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0025] like Figures 1 to 6As shown, a pulse automatic blowing and dust removal device for a shot blasting machine comprises a main body 1 of the shot blasting machine and a shot blasting wheel 3. A conveyor frame 2 is provided at the lower portion of the main body 1 of the shot blasting machine, and a conveyor roller is installed on the conveyor frame 2. An upper bracket 4 is fixedly installed at the top middle position of the main body 1 of the shot blasting machine, a control box 5 is installed above the upper bracket 4, and a microcomputer digital module and a pulse meter are provided in the control box 5. A lifting hydraulic rod 13 is fixedly installed below the upper bracket 4, and a lifting frame 16 is fixedly provided at the lower end of the lifting hydraulic rod 13. Purge sealing plates 17 are symmetrically provided on both sides of the lifting frame 16. A purge pipe 18 is provided on the plate 17, and a purge air pump 14 is installed on the top of the main body 1 of the shot blasting machine. Blowing windows 8 are opened on the top of the main body 1 of the shot blasting machine on both sides of the purge air pump 14. The blowing window 8 is equipped with a sealing cover plate 9. A connecting rod is provided on the top of the sealing cover plate 9. The side of the connecting rod is fixedly connected to the end of the electric telescopic rod 20. The electric telescopic rod 20 is fixedly installed on the upper end of the electric telescopic rod 19. The electric telescopic rod 19 is fixedly installed on the main body 1 of the shot blasting machine. The electric telescopic rod 19 and the electric telescopic rod 20 are used to adjust the position of the sealing cover plate 9.

[0026] Among them, the cross-section of the blowing window 8 is a stepped structure, and a matching boss 23 is provided on the bottom surface of the sealing cover plate 9, which is adapted to the hollow size of the blowing window 8. A sealing groove 21 is provided on the bottom surface of the sealing cover plate 9 on the outside of the matching boss 23, and a sealing ring 22 is installed in the sealing groove 21 to improve the sealing performance of the sealing cover plate 9 and the blowing window 8.

[0027] The upper end of the electric telescopic rod 19 is fixedly provided with a mounting seat, which is an L-shaped bent plate structure. The electric telescopic rod 20 is fixedly installed on the side of the mounting seat. Multiple groups of shot blasting wheels 3 are symmetrically installed on both sides of the main body 1 of the shot blasting machine. An operating box 10 is provided on the side of the shot blasting wheel 3 for controlling the working process of the shot blasting machine.

[0028] A dust collector 6 is provided on the side of the main body 1 of the shot blasting machine. The dust collector 6 is connected to the interior of the main body 1 of the shot blasting machine through a dust removal pipe 7 for performing dust removal during the shot blasting process.

[0029] The shot blasting machine main body 1 has symmetrically opened inlet and outlet doors 11 on both sides. The inlet and outlet doors 11 are equipped with protective curtains 12 for protection during the inlet and outlet process, reducing dust overflow and the probability of particle splashing during the shot blasting process.

[0030] There are two groups of purge pipes 18 symmetrically arranged. The two groups of purge pipes 18 are connected by an air supply connecting pipe 24. The air supply connecting pipe 24 is connected to the purge air pump 14 by a connecting hose 15. The air supply connecting pipe 24 is located near one end of the purge pipe 18 to avoid interference with the purge air pump 14 during the lifting and adjustment of the lifting frame 16.

[0031] The working principle of the present utility model is as follows: when the main body 1 of the shot blasting machine is performing shot blasting, the sealing cover plate 9 is used to seal the blowing window 8 to increase the sealing performance during the operation of the shot blasting machine and ensure the dust removal effect of the dust collector 6 during the shot blasting process. After the shot blasting machine completes the shot blasting operation, the electric telescopic rod 1 extends, driving the sealing cover plate 9 to move upward and separate from the blowing window 8. Then, the electric telescopic rod 20 contracts to make room for the lifting frame 16 to descend. The lifting hydraulic rod 13 drives the lifting frame 16 to move downward, so that the purge sealing plate 17 cooperates with the blowing window 8, and the lower end of the purge pipe 18 is inserted into the blowing window 8.

[0032] By attaching Figure 6 It can be seen that after the dust collector 6 is powered off, the live wire L transmits power to the microcomputer controller RT220K through the normally closed contact on the contactor of the dust collector 6. (When the dust collector 6 is working, the normally closed contact is open and cannot power the RT220K.) RT220K immediately outputs voltage, and the manual / automatic switch is turned down to power the pulse meter. The pulse meter automatically purges the filter cartridge according to the set pulse width and cycle, and automatically stops working after the time set by the microcomputer controller is reached. In manual mode, the manual / automatic switch can be turned up to perform dust removal, but it must be manually closed and turned to the middle position, otherwise the pulse meter will continue to work.

[0033] The control box 5 is provided with a microcomputer digital module and a pulse meter. The microcomputer digital module is RT220K. The module inputs AC 220V power. When the power is turned on, the output port L is immediately powered. It automatically powers off after the set time is up. The set time is controlled by the internal DIP switch. Different combinations can achieve different set times, and the set time range is wide.

[0034] After the purge and dust removal is completed, the lifting frame 16 and the sealing cover plate 9 are reset to ensure that the shot blasting machine is in normal working condition for the next use; the lifting hydraulic rod 13 is equipped with supporting devices such as a hydraulic pump, a pipeline, and a control valve. The electrical components such as the electric telescopic rod 19 and the electric telescopic rod 20 are electrically connected to the external power supply. The purge air pump 14 uses WM8040;

[0035] A power-on delay relay can be added to the pulse automatic control circuit to delay the start time of automatic blowing and dust removal; the utility model is provided with a blowing window 8 on the top of the main body 1 of the shot blasting machine, and the blowing window 8 is provided with an automatically adjustable and sealed cover 9 and an automatic blowing structure. The automatic blowing structure includes a lifting frame 16, a blowing pipe 18, and a blowing air pump 14, which can cooperate with the blowing window 8 to realize automatic blowing inside the main body 1 of the shot blasting machine. The automatic blowing structure is equipped with a control box 5, and a microcomputer digital module and a pulse meter are provided in the control box 5. It can realize automatic blowing at the set time and automatically cut off the power after the time is up. The operator does not need to wait on site, and it avoids forgetfulness and omissions. It can ensure that the shot blasting machine is automatically dusted in each shift, reduce management costs, and extend the practical life of the dust removal system of the shot blasting machine.

[0036] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above-mentioned technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
