Description

Technical Field

[0001] This utility model relates to the field of explosives production technology, specifically to an automated cleaning device for reaction vessels in explosives production sites. Background Technology

[0002] The design of the explosives production line involves some material adhering to the inner wall of the reactor after the reaction is completed. When cleaning is required, personnel must enter the explosives production area and use a fire extinguishing water pipe to repeatedly rinse the inner wall of the reactor. After rinsing, the water is discharged into the ditch. The entire reactor cleaning process requires manual operation, which greatly increases the labor intensity of personnel and the time spent entering the hazardous area. Summary of the Invention

[0003] This invention overcomes the shortcomings of existing technologies by providing an automated cleaning device for reactors in explosives production sites. It enables automated cleaning of reactors in explosives production sites, effectively reducing labor intensity, minimizing the time personnel spend in hazardous areas, and improving the inherent safety of explosives production.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an automated cleaning device for reaction vessels in explosives sites, including a cleaning water tank, a water outlet pipe connected to the cleaning water tank, a high-pressure water pump installed on the water outlet pipe, a cleaning telescopic device installed at the end of the water outlet pipe, the end of the water outlet pipe connected to the cleaning telescopic device extending into the interior of the reaction vessel and connected to a nozzle, the high-pressure water pump being electrically connected to a controller, and the controller being electrically connected to a computer.

[0005] Working process: When the reactor for producing explosives needs to be cleaned after completion, the operator sets the number of automatic flushing cycles on the computer in the main control room and clicks the automatic flushing button. The high-pressure flushing pump starts automatically, and the nozzles flush the inner wall of the reactor. After the high-pressure flushing pump has repeatedly flushed the reactor to the set number of cycles, it stops automatically, thus automating the cleaning of the reactor.

[0006] Furthermore, the nozzle is a pneumatic rotary nozzle.

[0007] Furthermore, the cleaning water tank is made of 304 stainless steel.

[0008] Furthermore, the cleaning telescopic device includes a motor and a connecting rod. The motor is connected to a lifting plate, and one end of the water outlet pipe connected to the nozzle is installed on the lifting plate. A positioning switch is installed on the lifting plate. The positioning switch and the motor are electrically connected to the control system. Multiple positioning blocks are connected from top to bottom on the connecting rod. The positioning switch and the positioning blocks cooperate to realize the positioning and lifting of the lifting plate.

[0009] Furthermore, the high-pressure water pump, the cleaning telescopic device, and the nozzle all have explosion-proof functions.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This utility model cleaning device is suitable for the automated cleaning of reaction vessels in explosives production sites. It not only realizes the automatic cleaning of reaction vessels in explosives production sites, reducing the time personnel spend entering dangerous areas and improving the inherent safety level of explosives production, but also greatly reduces the labor intensity of personnel.

[0016] The present invention will be further described below with reference to specific embodiments. Example 1

[0017] like Figure 1 As shown, an automated cleaning device for a reaction vessel in a pyrotechnics facility includes a cleaning water tank 2, which is connected to an outlet pipe. A high-pressure water pump 3 is installed on the outlet pipe, and a cleaning telescopic device 4 is installed at the end of the outlet pipe. The end of the outlet pipe connected to the cleaning telescopic device 4 extends into the reaction vessel 1 and is connected to a nozzle 5. The high-pressure water pump 3 is electrically connected to a controller, which is electrically connected to a computer. All components are connected by flanges for easy future inspection and maintenance.

[0018] Furthermore, the nozzle 5 is a pneumatic rotary nozzle.

[0019] Furthermore, the cleaning water tank 2 is made of 304 stainless steel; the welds are ground and polished, with no sharp edges or burrs, and a leak test is conducted before use.

[0020] Furthermore, the cleaning telescopic device 4 includes a motor 41 and a connecting rod (the motor 41 and the connecting rod are installed above the reactor 1 via a support frame or other brackets). The motor 41 is connected to a lifting plate 42, and one end of the water outlet pipe connected to the nozzle 5 is installed on the lifting plate 42. A positioning switch is installed on the lifting plate 42. The positioning switch and the motor are electrically connected to the control system. Multiple positioning blocks 43 are connected from top to bottom on the connecting rod (which can be increased or decreased according to the actual situation). The positioning switch and the positioning blocks 43 cooperate to realize the positioning and lifting of the lifting plate 42.

[0021] Positioning block 43 ensures that the lifting plate 42 stops precisely at a predetermined position, while the positioning switch detects the position of the lifting plate and sends an electrical signal to the control system. The control system further controls the mechanical actions (start and stop of motor 41) based on the received signal. When the lifting plate reaches the predetermined position, the positioning switch is triggered, and the control system executes the corresponding operation after receiving the signal. Positioning block 43 and positioning switch are usually used together. By installing the positioning switch on the lifting plate, point-to-point cleaning can be achieved. The position of the positioning switch can be set according to the actual situation to meet the point-to-point cleaning needs of different reaction vessels.

[0022] Furthermore, the high-pressure water pump 3, the cleaning telescopic device 4, and the nozzle 5 all have explosion-proof functions to ensure safe use.

[0023] Working process: When the reactor for producing explosives needs to be cleaned after completion, the operator sets the number of automatic flushing cycles on the computer in the main control room and clicks the automatic flushing button. The high-pressure flushing pump 3 starts automatically, and the nozzle (high-pressure water washing nozzle) 5 flushes the inner wall of the reactor. The high-pressure water washing nozzle 3 sprays high-pressure water from 360° to clean the reactor, ensuring that the reactor is clean. After the high-pressure flushing pump 3 has flushed repeatedly for the set number of times, it automatically stops flushing, thereby realizing the automation of reactor cleaning.

[0024] This utility model relates to an automated cleaning device for reaction vessels in explosives and pyrotechnics sites. The device achieves significant cleaning results, meeting the cleaning requirements of the production line. The inner wall of the vessel and the impeller are thoroughly cleaned, free of dirt. This automated cleaning device for reaction vessels in explosives and pyrotechnics sites saves considerable labor costs, removes personnel from hazardous areas, and achieves inherent safety.
