Description

Technical Field

[0001] This invention relates to the field of paste production technology, specifically to a mixing tank cleaning device for paste filling materials. Background Technology

[0002] In industrial fields such as mining backfilling, building materials production, and chemical reactions, the mixing of paste-based backfill materials (such as paste concrete and tailings cemented backfill) is one of the key processes. After use, a large amount of paste material remains on the inner wall and agitator blades of the mixing tank. This material has high viscosity and is prone to solidification. If it is not cleaned in time, it will seriously affect the uniformity of the next mixing and the service life of the equipment. Currently, the cleaning of paste-based backfill material mixing tanks mainly adopts the following methods:

[0003] Manual high-pressure water gun rinsing: Operators hold a high-pressure water gun and insert it into the tank to rinse. This method is labor-intensive, inefficient, and the environment inside the tank is harsh, posing safety hazards.

[0004] Fixed spray system: Fixed spray heads are installed on the top or inside the tank, and water is sprayed through rotation for cleaning. However, the coverage of fixed spray heads is limited, there are blind spots in cleaning, and it is difficult to adapt to mixing tanks of different depths and diameters.

[0005] Simple telescopic cleaning device: Some devices use telescopic spray pipes, but they can only achieve straight spraying and cannot make the cleaning elements fit against the tank wall, resulting in poor cleaning effect for highly adhesive paste materials.

[0006] Existing cleaning equipment generally suffers from the following shortcomings:

[0007] Poor adaptability: Different mixing tanks have large differences in height and diameter, and traditional cleaning devices cannot flexibly adjust the length and angle, making it difficult to adapt to tanks of various sizes.

[0008] Incomplete cleaning: The paste material has strong adhesion and cannot be removed by water jet alone. It requires the cleaning element to scrape against the tank wall to remove it completely.

[0009] Lack of contact mechanism: The existing device's cleaning head or nozzle cannot maintain constant contact with the tank wall, resulting in poor cleaning effect on curved or irregular parts of the tank wall.

[0010] Low level of automation: The actions such as extension, rotation and water spraying during the cleaning process mostly rely on manual operation or semi-automatic control, resulting in low efficiency.

[0011] Therefore, there is an urgent need for a cleaning device for paste filling material mixing tanks that can adapt to the size of the mixing tank, achieve conformal cleaning, and has a high degree of automation. Summary of the Invention

[0012] The present invention provides a mixing tank cleaning device for paste filling materials, which solves the problems mentioned in the background art.

[0016] As a preferred embodiment of the present invention, the height adjustment mechanism includes a motor base fixed on a mounting frame, a first motor mounted on the motor base, the first motor being a double-headed motor, the output shaft of the first motor being fixedly connected to two first rotating shafts, the first rotating shafts being fixedly connected to a first bevel gear, the first bevel gear meshing with a second bevel gear, the second bevel gear being coaxially fixedly connected to a threaded rod, the threaded rod being rotatably connected to the mounting frame, the threaded rod being threadedly connected to a lifting plate, and the lifting plate being slidably connected to the mounting frame.

[0017] As a preferred embodiment of the present invention, the deflection plate mechanism includes two second rotating shafts, which are respectively disposed on two lifting plates. A deflection plate is fixedly connected between the two second rotating shafts. One of the second rotating shafts is coaxially fixedly connected to a first gear. A second motor is provided on the lifting plate. The output shaft of the second motor is fixedly connected to the second gear. The second gear meshes with the first gear.

[0018] As a preferred embodiment of the present invention, the rotating sleeve mechanism includes a third motor fixed to the deflection plate, the output shaft of the third motor being fixedly connected to a third gear, the third gear meshing with a gear ring, the inner side of the gear ring being fixedly connected to a rotating sleeve, the rotating sleeve and the deflection plate being rotatably connected, and a drive bar being fixedly connected to the inner axial direction of the rotating sleeve.

[0019] As a preferred embodiment of the present invention, the telescopic tube mechanism includes a first electric telescopic rod fixed on the deflection plate and located on the same side as the third motor. The end of the first electric telescopic rod away from the deflection plate is fixedly connected to a rotating ring. The rotating ring is rotatably connected to a first mounting shell. The first mounting shell is fixedly connected to a telescopic tube. The telescopic tube passes through a rotating sleeve. The telescopic tube and the rotating sleeve are slidably connected. A drive groove is provided in the axial direction of the inner side of the telescopic tube. A drive bar is located in the drive groove. A plurality of first cleaning holes are provided on the surface of the telescopic tube away from the third motor.

[0020] As a preferred embodiment of the present invention, the displacement liquid inlet mechanism includes a second electric telescopic rod fixed to the first mounting shell away from the rotating ring. The end of the second electric telescopic rod away from the first mounting shell is fixedly connected to the second mounting shell. The side of the second mounting shell away from the second electric telescopic rod is rotatably connected to the liquid inlet pipe. The second mounting shell and the inner tube are fixedly connected. The inner tube passes through the first mounting shell and the telescopic pipe. The inner tube is slidably connected to the first mounting shell and the telescopic pipe. The inner tube passes through the telescopic pipe. A plurality of second cleaning holes are provided on the side of the inner tube.

[0021] As a preferred embodiment of the present invention, the fitting cleaning mechanism includes a first displacement seat fixed to the outside of the telescopic tube. There are two first displacement seats. The first displacement seat is rotatably connected to a folding rod. The folding rod is rotatably connected to a second displacement seat. The second displacement seat is fixedly connected to a flexible cleaning plate. The inner tube is fixedly connected to a third displacement seat. The third displacement seat is rotatably connected to a displacement rod. The displacement rod is rotatably connected to a fourth displacement seat. The fourth displacement seat and the folding rod are fixedly connected.

[0022] The present invention has the following advantages:

[0023] 1. Height self-adaptation to different tank depths: The height adjustment mechanism uses a dual-head motor to synchronously drive the threaded rods on both sides, which drives the lifting plate to rise and fall smoothly, thereby adjusting the overall height of the deflection plate mechanism and the telescopic tube mechanism. It can adapt to mixing tanks of different heights without the need to change equipment, and has strong versatility.

[0024] 2. Adjustable angle to adapt to tank opening tilt: The deflection plate mechanism is driven by the second motor to mesh the first gear and the second gear, causing the deflection plate to swing around the second shaft, so that the telescopic tube mechanism can extend into the mixing tank at different angles to adapt to the tank opening position deviation or tank tilt, ensuring that the cleaning device can smoothly enter the tank.

[0025] 3. Large telescopic range, adaptable to different depths: The rotating sleeve mechanism is driven by a third motor to rotate the rotating sleeve. The telescopic tube and the rotating sleeve are slidably engaged through the drive bar and drive groove. It can rotate synchronously with the rotating sleeve and can also extend and retract axially under the drive of the first electric telescopic rod, adapting to the tank cleaning needs of different depths.

[0026] 4. Adhesive cleaning to remove stubborn residue: The adhesive cleaning mechanism adopts a linkage structure. When the inner tube extends or retracts, the flexible cleaning plate is driven to open or close radially through the displacement rod and folding rod, so that the flexible cleaning plate always adheres to the inner wall of the mixing tank. The flexible cleaning plate rotates with the extension tube, scraping and cleaning the inner wall. Combined with the high-pressure water flow, it effectively removes adhering paste materials.

[0027] 5. Dual spraying for thorough cleaning: The telescopic tube has a first cleaning hole on its surface, and the inner tube has a second cleaning hole on its surface. Cleaning fluid enters through the inner tube and exits through the second cleaning hole, while simultaneously exiting through the first cleaning hole on the telescopic tube, achieving dual spraying to cover the tank wall and agitator blades. The inner tube can extend further under the drive of a second electric telescopic rod, extending the cleaning range.

[0028] 6. Easy to move and flexible to operate: The bottom of the fixed plate is equipped with a moving wheel mechanism. The moving seat shaft can rotate, and the moving wheel seats can turn, allowing the device to be moved flexibly within the workshop for easy cleaning of mixing tanks in different locations. The moving wheels have a built-in locking function to fix the position during cleaning.

[0029] 7. High degree of automation: All adjustment, extension, rotation and spraying actions can be automatically programmed and controlled by the control system, reducing manual intervention, improving cleaning efficiency and consistency, and reducing labor intensity and safety risks.
