Description

Technical Field

[0001] This utility model belongs to the field of ammunition technology, specifically relating to an automatic cleaning device for the blades of a vertical kneader at the end of a casting explosive mixing process. Background Technology

[0002] Currently, the method used for cleaning the blades is still manual, with operators using hand tools to physically scrape off the powdery material. During cleaning, after the mixing pot is lowered and the machine stops, the operator manually pushes the trapezoidal platform to the side of the pot and secures it. Then, they ascend the ladder to the blades and use a wooden shovel or copper knife to gently scrape the powdery material from the blades into the pot. The entire process requires at least three people on-site, involves a long preparation time, and the operators are in direct contact with explosives in a hazardous working environment. The blade position needs to be adjusted 2-4 times for cleaning, taking approximately 15-20 minutes. The cleaning time constitutes a significant portion of the total mixing process time, resulting in low efficiency. Furthermore, the personnel cleaning the blades must climb the ladder, posing a risk of working at height.

[0003] To address safety issues in the production process, improve work efficiency, and ensure product quality, it is an urgent need to actively promote and implement the automation and unmanned transformation of the production process. Utility Model Content

[0035] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0036] This invention designs a vertical kneader blade cleaning device for the final stage of the explosive mixing process. It primarily addresses the problems associated with manual blade surface cleaning and maintenance during the production process, where personnel directly handle the explosives: 1. the problem of manual operation in hazardous processes; 2. the problem of work efficiency; and 3. the problem of incomplete manual blade cleaning. The device designed in this invention achieves human-machine isolation in hazardous processes, solving the problem of manual operation in these processes. During the cleaning process, the blades in the cleaning chamber are driven by the rotation of the vertical kneader, eliminating the need for manual adjustment of blade position and thus solving the problem of low work efficiency. The device uses a combination of high-pressure water guns and air guns to clean the blade surface, achieving thorough cleaning and resolving the problem of incomplete manual blade cleaning.

[0037] Figure 1 This is an overall structural diagram of a vertical kneader blade cleaning device at the end of a casting explosive mixing process. The device mainly consists of a cleaning chamber 2, a high-pressure pipeline 3, and a high-pressure pump set 4.

[0038] Figure 2 This is a structural diagram of a vertical kneader 1, which mainly consists of a vertical kneader body 11 and blades 12. The vertical kneader body 11 adopts a welded steel frame structure, and its main function is to mount and install the blades 12.

[0039] Figure 3 This is a structural diagram of the cleaning chamber 2, which consists of a main cleaning chamber body, a filtration system 22, a cleaning spray gun system 23, a drying system 24, a water supply pipeline 25, and a pneumatic pipeline 26. The top of the main cleaning chamber body is designed with an opening that matches the shape of the blade 12. After the main cleaning chamber body moves to the cleaning station and docks with the blade 12, it forms a closed cavity with the blade 12. The bottom of the main cleaning chamber body has a conical design for the collection and discharge of explosion-proof wastewater and waste materials. The filtration system 22 is integrated and installed below the main cleaning chamber body. After the cleaning operation is completed, the drawer can be easily pulled out to filter the solid waste. A trolley 21 is integrated below the filtration system 22 to carry the main body of the cleaning chamber into and out of the cleaning station. An external inspection door facilitates maintenance work such as nozzle and cleaning spray gun replacement. The cleaning spray gun system 23 is a spray gun array fixed to the inner wall of the cleaning chamber. It removes residual material from the surface of the blades 12 by cooperating with the rotation of the blades 12. The simultaneous activation of each spray gun and the rotation of the blades 12 are interlocked, meaning the spray guns are activated only after the blades 12 rotate, preventing damage to the surface of the blades 12 due to high-pressure jets. The spray guns are designed for easy disassembly, replacement, and maintenance. The drying system 24 is integrated into the inner wall of the cleaning chamber. After cleaning, it dries the blades 12, facilitating their rapid deployment. A water supply pipe 25 is connected to a high-pressure pump unit 4 via a high-pressure pipe 3, and a pneumatic pipe 26 is connected to the high-pressure pump unit 4, supplying water and air to the cleaning chamber 2 respectively. The water supply pipe 25 is installed at the bottom of the trolley. The pneumatic pipe 26 provides air to the drying system 24.

[0040] Figure 4 This is a structural diagram of the high-pressure pipeline 3, which consists of a high-pressure hose 31 and a coiler 32. High-pressure water is delivered from the high-pressure pump unit 3 to the cleaning spray gun system 23 via a dedicated high-pressure hose 31. The high-pressure hose 31 is equipped with a safety sleeve, and the interface connecting it to the water supply pipeline 25 is equipped with an anti-detachment safety lock, both of which have passed a special pressure test to ensure safe use. The high-pressure hose 31 is retracted and extended via the coiler 32, facilitating the retraction and unfolding of the high-pressure hose 31 when the cleaning chamber 2 enters and exits the cleaning station, ensuring a clean floor after the cleaning chamber 2 is returned to its position, thus not affecting the entry and exit of the vertical kneader 1.

[0041] Figure 5 This is a structural diagram of the high-pressure pump unit 4, which consists of a three-plunger pump hydraulic end 41, a high-stability power end 43, a water inlet management system 44, and a hot-dip galvanized chassis 45. The main function of the high-pressure pump unit 4 is to provide water and air to the cleaning chamber 2.
