Description

Technical Field

[0001] This invention belongs to the field of vertical mixing tank cleaning technology, specifically relating to an automatic cleaning device and method for using a vertical mixing tank for filling. Background Technology

[0002] Vertical mixing tanks are widely used equipment in the tailings backfilling process of metal mines. Their main function is to uniformly mix tailings slurry with cement. The main structure of a vertical mixing tank for backfilling is as follows: Figure 1 As shown. Typical backfilling operations take a long time, ranging from 6-8 hours to 20-22 hours. Because cement is added as dry powder to the backfilling mixing tank and mixed with the tailings slurry, prolonged backfilling production causes a significant amount of cement and splashed tailings slurry to adhere to the tank walls. If not cleaned promptly, these substances will harden into cement lumps in a humid environment. As backfilling time increases, these cement lumps gradually enlarge and extend into the tank, reducing its effective volume and affecting the mixing efficiency of the backfill slurry. Furthermore, these cement lumps can detach and enter the backfilling pipeline, easily causing blockages and leading to backfilling accidents.

[0003] Currently, the conventional methods for cleaning filling mixing tanks in filling operations include: 1. Vigorous stirring and cleaning can cause the hardened material adhering to the barrel wall to fall off, which may cause blockage of the filling pipe and lead to filling accidents; 2. It is difficult to completely clean the hardened cement mixture adhering to the barrel wall. As production progresses, more and more hardened cement mixture accumulates on the barrel wall and extends into the interior of the mixing barrel, thus affecting the filling effect of the mixing barrel and causing a decline in filling quality. 3. Manual entry into the mixing tank is required for cleaning, which results in high labor intensity for filling personnel and reduces production efficiency. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides an automatic cleaning device for vertical mixing tanks used in filling processes, characterized by high cleaning efficiency and excellent cleaning effect.

[0005] The present invention also provides a method for using an automatic cleaning device for a vertical mixing tank used for filling.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic cleaning device for a vertical mixing tank used for filling, comprising a vertical mixing tank body, a tank cover fixed to the upper part of the interior of the vertical mixing tank body, a drive motor installed in the middle of the upper part of the tank cover, a side wall cleaning component provided at the output end of the drive motor, an adjusting support component installed on the side wall surface of the vertical mixing tank body, an installation plate fixed to one side of the adjusting support component, an air intake pump provided on one side of the upper end of the installation plate, a water supply pipe connected to one end of the air intake pump, a solenoid valve connected to the surface of the water supply pipe, a plurality of spray pipes connected to the bottom end of the water supply pipe, a high-pressure water pump provided on the other side of the upper end of the installation plate, a solenoid valve connected to the output end of the high-pressure water pump, a PLC controller fixed to one side of the installation plate, and a connecting cable electrically connected to one end of the PLC controller.

[0007] Furthermore, in this invention, the water spray pipe includes a water spray branch pipe, which is sealed to the bottom surface of the water supply pipe. The bottom end of the water spray branch pipe is connected to a nozzle rotating shaft, and the bottom end of the nozzle rotating shaft is connected to a nozzle body.

[0008] Furthermore, in this invention, the output end of the high-pressure water pump is connected to an L-shaped pipe corresponding to the second solenoid valve, and one end of the L-shaped pipe is connected to one side of the water supply pipe.

[0009] Furthermore, in this invention, the adjusting support assembly includes a guide frame, which is symmetrically fixed on both sides of the vertical mixing tank body. A support ring is sleeved on the surface of the guide frame, and several positioning holes are symmetrically opened on the inner wall of the support ring. A support frame is fixed on one side of the positioning hole, and a limit groove is opened inside the support ring corresponding to the guide frame. A fastening bolt is connected to one side of the limit groove.

[0010] Furthermore, in this invention, the upper end of the guide frame is provided with several through holes.

[0011] Furthermore, in this invention, an extension plate is fixed to one side of the support ring corresponding to the mounting plate, and threaded holes are symmetrically opened inside the extension plate.

[0012] Furthermore, in this invention, the sidewall cleaning assembly includes a stirring rod, which is fixedly installed at the bottom of the drive motor. A fixing rod is symmetrically fixed in the middle of the surface of the stirring rod. A protrusion is installed at one end of the fixing rod, a scraper is fixed on one side of the protrusion, a nut is provided on the surface of the protrusion, and a fixing bolt is connected to the inside of the fixing rod corresponding to the nut.

[0013] Furthermore, in this invention, a water-passing groove is formed inside the scraper, and the surface of the scraper is in close contact with the inner wall surface of the vertical mixing tank body.

[0014] An automatic cleaning device for a vertical mixing tank used for filling, the method of using the automatic cleaning device for a vertical mixing tank used for filling is as follows: S1. Before cleaning the inside of the vertical mixing tank, move the support ring along the guide frame to adjust its height, then tighten the bolts to fix it to the surface of the guide frame, then use bolts to fix the support frame to the appropriate positioning hole, and use screws to install the mounting plate on the upper end of the extension plate for use. S2. Open the bucket lid and connect the water spray branch pipe through the opening in the bucket lid to the bottom of the water supply pipe. The support frame can support the water supply pipe to ensure stable use. Then, use the PLC controller to control the operation of each component. When using high-pressure water cleaning alone, close the solenoid valve one and the air pump, and turn on the high-pressure water pump and solenoid valve two. At this time, the external water flow enters the water supply pipe through the L-shaped pipe, then flows into the water spray branch pipe and finally enters the nozzle body. The high-pressure water is sprayed onto the inner wall surface of the vertical mixing tank body through the water outlet on the nozzle body. The water spray branch pipe is connected to the nozzle rotating shaft, which enables the nozzle body to rotate and spray during operation, thereby ensuring the cleaning effect. The cleaning time is generally 1 to 3 minutes. At the same time, some water flows into the water tank. When the drive motor drives the stirring rod to run, the scraper continuously scrapes and cleans the inner wall of the vertical mixing tank body. The water flow in the water tank can assist in rinsing and cleaning, improving the quality of equipment use. The sludge after rinsing is discharged from the discharge port at the bottom of the vertical mixing tank body. S3. Individual high-pressure air cleaning: This involves closing the high-pressure water pump and solenoid valve two, and opening solenoid valve one and the air intake pump. At this time, external high-pressure air enters the water spray branch pipe through the water supply pipe and finally enters the nozzle body. The high-pressure air is then sprayed onto the inner wall surface of the vertical mixing tank through the water outlet on the nozzle body. The water spray branch pipe is connected to the nozzle rotation shaft, which enables the nozzle body to rotate and spray during operation, thus ensuring the cleaning effect. The cleaning time is generally 1 to 3 minutes. The sludge after rinsing is discharged from the discharge port at the bottom of the vertical mixing tank. S4. Combined cleaning with high-pressure air and high-pressure water: In each cleaning operation, solenoid valve one and the air intake pump can be turned on first to carry out the cleaning operation. After the operation is completed, solenoid valve one and the air intake pump are turned off, and then the high-pressure water pump and solenoid valve two are turned on again to carry out the cleaning operation. The completion of the cleaning is counted as one cleaning operation. Alternatively, high-pressure water cleaning can be carried out first and then high-pressure air cleaning. Generally, the cleaning operation time is 3 to 5 minutes, with high-pressure air and high-pressure water cleaning each accounting for half of the time. The sludge after rinsing is discharged from the discharge port at the bottom of the vertical mixing tank.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up an air intake pump and a high-pressure water pump connected to a water supply pipe and operating through nozzles extending into the vertical mixing tank, can achieve automatic cleaning during the filling process, eliminating the need for manual entry into the mixing tank for cleaning. It can also achieve remote, timed, and fixed-point automatic cleaning, which can greatly reduce the labor intensity of personnel, improve work efficiency, ensure work safety, and improve cleaning quality. Furthermore, the air intake pump and the high-pressure water pump can work independently or in combination to improve the effectiveness of the equipment.

[0016] 2. By setting an adjustable support component, the height of the support ring can be adjusted along the guide frame according to the usage needs. Then, the fastening bolts are tightened to fix it on the surface of the guide frame. The support frame is then fixed in the appropriate positioning hole with bolts, and the mounting plate is installed on the upper end of the extension plate with screws. This improves the stability of the water supply pipe installation and ensures the quality of equipment use.

[0017] 3. By setting up a side wall cleaning component, the scraper continuously scrapes and cleans the inner wall of the vertical mixing tank body when the drive motor drives the stirring rod, and the water flow in the water tank can assist in rinsing and cleaning, thereby improving the quality of equipment use.

The slurry after rinsing is discharged from the discharge port at the bottom of the vertical mixing tank body 1.

[0038] The working principle and usage process of the present invention: When using the present invention, before cleaning the inside of the vertical mixing tank body 1, move the support ring 53 along the guide frame 57 to adjust its usage height, then tighten the fastening bolt 56 to fix it on the surface of the guide frame 57, then use bolts to fix the support frame 52 in the appropriate positioning hole 51, and use screws to install the mounting plate 8 on the upper end of the extension plate 54 for use. Open the bucket lid 3 and connect the water spray branch pipe 61 through the opening in the bucket lid 3 to the bottom of the water supply pipe 7. The support frame 52 can support the water supply pipe 7 to ensure the stability of the water supply pipe 7. Then, use the PLC controller 12 to control the operation of each component. When using high-pressure water cleaning alone, close the solenoid valve 9 and the air intake pump 10, and turn on the high-pressure water pump 11 and the solenoid valve 14.

At this time, external high-pressure air enters the water spray branch pipe 61 through the water supply pipe 7 and finally enters the nozzle body 63. The high-pressure air is then sprayed onto the inner wall surface of the vertical mixing tank body 1 through the water outlet on the nozzle body 63. The water spray branch pipe 61 is connected to the nozzle rotation shaft 62, which enables the nozzle body 63 to rotate and spray during operation, thereby ensuring the cleaning effect.

Then the high-pressure water pump 11 and the solenoid valve 24 are turned on again to carry out the cleaning operation. The completion of the cleaning is counted as one cleaning operation. Alternatively, high-pressure water cleaning can be carried out first and then high-pressure air cleaning can be carried out.
