Description

Technical Field

[0001] This utility model relates to a headstock cleaning device, and more particularly to a headstock cleaning device for preventing blockage of calcium carbonate. Background Technology

[0002] In the wet production or deep processing of calcium carbonate (especially light and heavy calcium carbonate), the calcium carbonate head mill is one of the core grinding equipment. It is mainly used to refine coarse-grained calcium carbonate slurry to micron or submicron levels, meeting the demand of industries such as coatings, papermaking, and plastics for "high fineness and narrow particle size distribution" of calcium carbonate powder. Essentially, it is a wet circulating grinding device that achieves particle crushing and refinement through the collision and shearing action of grinding media (such as ceramic balls and steel balls). However, this process can cause the slurry to adhere to the inner wall of the equipment, the surface of the media, and the pipes, forming stubborn deposits that require a cleaning device to remove.

[0003] With the industry's increasing demands for the purity and fineness of calcium carbonate products (e.g., coating-grade calcium carbonate must achieve D97 ≤ 0.5μm), traditional manual cleaning or simple spraying is no longer sufficient to meet cleaning requirements. Calcium carbonate slurry is viscous; incomplete cleaning can lead to slurry solidification inside the equipment, affecting the uniformity of subsequent slurry production, and causing blockage at the cleaning output due to solidified calcium carbonate slurry. Therefore, it is necessary to design a cleaning device that can efficiently clean the slurry machine and prevent calcium carbonate blockage from affecting cleaning quality. Utility Model Content

[0004] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a cleaning device for a calcium carbonate head machine that prevents blockage, thereby achieving efficient and rapid cleaning of the head machine and increasing the anti-blockage function.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A cleaning device for preventing blockage of calcium carbonate slurry machine is installed on a container tank. It includes a reciprocating cleaning mechanism installed on the upper part of the container tank to assist in cleaning, and a liquid conveying mechanism for conveying clean water and cleaning agent to the reciprocating cleaning mechanism. The reciprocating cleaning mechanism includes a rotating tube that is reciprocally rotated on the container barrel for spraying at different angles on the inner wall of the container barrel; The inner side of the rotating tube, located inside the container, is equipped with several anti-clogging nozzles for preventing nozzle clogging.

[0006] Preferably, the outer periphery of the rotating tube is provided with a plurality of rotating teeth, and a support base is provided on the outer side of the container. A bidirectional motor is vertically mounted on the support base, and the rotating end of the bidirectional motor is provided with a drive gear that cooperates with the plurality of rotating teeth. The drive gear meshes with two adjacent rotating teeth for driving the rotating tube to rotate in both directions.

[0007] Preferably, rotating rings are provided at both the upper and lower ends of the rotating tube, and the rotating rings are sleeved on the inner side of the receiving barrel for the smooth rotation of the rotating tube.

[0008] Preferably, a sealing ring is fitted on the outer side of the container, and the end of the sealing ring is in contact with the rotating tube for a stable seal between the rotating tube and the container.

[0009] Preferably, the liquid conveying mechanism includes an air pump and a water pump connected in connection with the rotating pipe. The air pump and water pump are located on the outside of the container. The input end of the water pump is provided with a conveying pipe, and the lower end of the conveying pipe is provided with a clear water tank and a dissolving tank for conveying different types of liquids.

[0010] Preferably, both the top of the water tank and the dissolving tank are provided with feeding ends, and control valves are provided between the conveying pipe and the water tank and the dissolving tank for opening and closing the water tank and the dissolving tank respectively.

[0011] Preferably, the anti-clogging nozzle includes an output seat fixed inside the rotating tube, a flexible cover extending through the end of the output seat, a disassembly part at the end of the flexible cover, an output end at the end of the disassembly part, a rotating wheel rotatably disposed in the disassembly part, and multiple centrifugal blades arranged in a ring on the inner side of the rotating wheel for accelerating the output liquid and preventing nozzle clogging.

[0012] Preferably, the middle part of the disassembly section is configured as a threaded detachable structure, and a number of sliding balls are provided on the outer side of the rotating wheel. The sliding balls are limited and slidably disposed on the inner wall of the disassembly section for quick disassembly to prevent clogging of the nozzle.

[0013] Preferably, an extension baffle is provided on the upper side of the output end, and a one-way door is rotatably provided at the port of the output end. The opening direction of the one-way door is downward, which is used for anti-clogging treatment of the nozzle.

[0014] Compared with existing technologies, the anti-clogging calcium carbonate slurry cleaning device provided by this utility model, through the coordinated use of a liquid conveying mechanism and a reciprocating cleaning mechanism, facilitates the use of a dissolving tank and a water pump in the liquid conveying mechanism to spray a weakly acidic cleaning agent onto the inner wall of the container, causing a chemical reaction between the agent and the calcium carbonate slurry that has accumulated and solidified on the inner wall of the container. Simultaneously, the reciprocating cleaning mechanism drives the reciprocating rotation of multiple anti-clogging nozzles, flushing the inner wall of the container at different angles. The water pump delivers clean water from the clean water tank to the anti-clogging nozzles, flushing away the cleaning agent and solidified calcium carbonate, increasing the cleanliness and service life of the container. The use of an air pump to deliver high-pressure gas to the rotating tube increases the liquid flow rate, allowing the calcium carbonate slurry to quickly separate from the inner wall of the container and clean the liquid inside the closed cleaning device, preventing calcium carbonate blockage in the container and the cleaning device, and improving the cleaning rate.

[0015] The use of the disassembly section in the anti-clogging nozzle allows for internal disassembly and maintenance. The combined use of the extension baffle and one-way door prevents calcium carbonate from entering. Furthermore, the use of the rotating wheel and multiple centrifugal blades facilitates the accelerated processing of the incoming liquid, flushing the output end of the anti-clogging nozzle to prevent calcium carbonate from accumulating or sticking to the output end, thus improving the anti-clogging effect of the cleaning device.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be described in more detail below with reference to the accompanying drawings. Note: The described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0021] As attached Figure 1 To be continued Figure 7 As shown, the anti-clogging calcium carbonate slurry cleaning device provided in this embodiment of the present invention addresses the shortcomings of existing internal cleaning technologies for calcium carbonate slurry machines. These technologies involve installing nozzles inside the slurry machine and connecting an external water pump 8. The water pump 8 is switched on and off according to cleaning needs, supplying clean water to the nozzles to clean the inner wall of the container 1. The cleaning process ends when the liquid at the output of the container 1 is clear. However, this method leaves calcium carbonate slurry residue inside the container 1, failing to remove the residue and solidified slurry. Therefore, the existing cleaning device needs improvement. The cleaning device of this invention mainly comprises two parts: a reciprocating cleaning mechanism 9 located on the upper part of the container 1 and used in conjunction with the cleaning process; and a liquid conveying mechanism 2 that supplies clean water and cleaning agent to the reciprocating cleaning mechanism 9. Based on the remaining slurry inside the headstock machine, the staff can perform the following operations through the liquid conveying mechanism 2: ① Supply clean water to the reciprocating cleaning mechanism 9, which sprays it into the container 1 at multiple angles to help remove excess calcium carbonate slurry; ② Supply cleaning agent to the container 1 to react with the calcium carbonate remaining inside to clean the solidified slurry; ③ Finally, supply clean water to rinse, while simultaneously injecting high-pressure gas through the air pump 7. This increases the pressure of the liquid output by the water pump 8 (enhancing the rinsing force) and, after stopping the liquid supply, discharges the residual liquid in the rotating pipe 10 (to prevent corrosion), thus completing the headstock machine cleaning work.

[0022] like Figure 2 and 3 As shown, when rinsing the inside of the container 1, the reciprocating cleaning mechanism 9 uses a rotating tube 10 rotatably mounted on the container 1. Several rotating teeth 11 are provided on the outer periphery of the rotating tube 10. A support base 12 is fixedly mounted on the outer side of the container 1. A bidirectional motor 13 is vertically mounted on the support base 12 as a driving device. A drive gear 14 is provided on the rotating end of the bidirectional motor 13. At the same time, the outer teeth of the drive gear 14 mesh with two adjacent rotating teeth 11 for driving the rotating tube 10 in both forward and reverse directions. Using the existing forward and reverse drive technology of motors, the bidirectional motor 13 can drive the rotating tube 10 to rotate continuously in both forward and reverse directions (its rotation range is 0-170°). Through the setting of several anti-clogging nozzles 17 on the inner side of the rotating tube 10, and the separate delivery of clean water and cleaning agent to the rotating tube 10 by the liquid delivery mechanism 2, the inside of the container 1 can be sprayed at different angles to thoroughly rinse and increase the cleanliness.

[0023] like Figure 2 and 3 As shown, in some embodiments, when the rotating tube 10 rotates at an angle on the container 1, the rotating rings 15, which are sleeved on the inner side of the container 1 at both ends of the rotating tube 10, are used for limiting the rotation and increasing the stability of the rotation of the rotating tube 10. At the same time, in some embodiments, a sealing ring 16 is fixedly sleeved on the outer side of the container 1, and the end of the sealing ring 16 rests on the outer side of the rotating tube 10 and fits against the rotating tube 10, so as to stably seal the rotating tube 10 and the container 1, thereby increasing the safety of the rotation of the rotating tube 10 (preventing liquid leakage).

[0024] like Figure 1 and 4As shown, when the cleaning device transports liquid, it uses a liquid transport mechanism 2 as a liquid drive unit, an air pump 7 located outside the container 1 as a gas drive device, and a water pump 8 as a liquid transport device. The air pump 7 and the water pump 8 are connected to the rotating pipe 10 through a flexible pipe that adapts to the rotation angle of the rotating pipe 10. The length of the flexible pipe is adapted to the reciprocating angle of the rotating pipe 10. The input end of the water pump 8 is provided with a transport pipe 5. The lower end of the transport pipe 5 is connected to a clean water tank 3 (for storing clean water) and a dissolving tank 4 (for storing cleaning agent). The top of both the clean water tank 3 and the dissolving tank 4 is provided with a feeding end for easy liquid addition, and the clean water tank 3 can be connected to an external water source to achieve continuous liquid supply. Then, control valves 6 are provided at the ends of the transport pipe 5 near the clean water tank 3 and the dissolving tank 4 to control the opening and closing of the clean water tank 3 and the dissolving tank 4 respectively, so as to realize the separate transport of different types of liquids. By supplying high-pressure gas to the rotating tube 10 via the air pump 7, two effects can be achieved: ① Increase the pressure of the liquid input to the water pump 8, improve the impact force of the output liquid, and ensure the cleanliness of the inside of the container 1; ② After the liquid supply stops, discharge the residual liquid in the rotating tube 10, improve the cleanliness of the cleaning device itself, and extend its service life.

[0025] like Figure 5 and 6 As shown, when liquid is output from the anti-clogging nozzle 17, in order to prevent the slurry inside the container 1 from clogging the nozzle, the anti-clogging nozzle 17 is provided with an output seat 18 inside the rotating tube 10. A flexible cover 19 (made of a highly elastic metal material, such as spring steel, which provides buffer protection for the anti-clogging nozzle 17 and improves the overall structural flexibility) is provided through the end of the flexible cover 19. The end of the flexible cover 19 is provided with a disassembly part 20. The middle of the disassembly part 20 adopts a threaded detachable structure, which can realize the quick disassembly of the anti-clogging nozzle 17 and facilitate the cleaning of residual slurry inside. The end of the disassembly part 20 is provided with an output end 21, which serves as an output channel for liquid or gas. In addition, a rotating wheel 24 is rotatably installed inside the disassembly section 20, with several sliding balls on its outer side (which slide along the inner wall of the disassembly section 20 for limitation), and multiple centrifugal blades 25 distributed in a ring on its inner side; when liquid or gas is delivered to the disassembly section 20, it will drive the rotating wheel 24 to rotate, and the centrifugal blades 25 can accelerate the liquid / gas and increase the output pressure (disperse the liquid to improve the flushing effect), while cleaning the residual slurry on the inner wall of the disassembly section 20, further improving the cleanliness.

[0026] As shown in Figure 7, to further prevent slurry from the container 1 from entering the anti-clogging nozzle 17, the output end 21 is equipped with a double protective structure: ① An extension baffle 22 is provided on the upper side of the output end 21 (extending outward by 5-8mm to block slurry dripping in from above); ② A one-way door 23 with an opening facing downwards is rotatably installed at the port of the output end 21 (the rotation range of the one-way door 23 and the output end 21 is 0-70°, closing by gravity when there is no liquid / gas, and being pushed open when there is liquid / gas output). This design keeps the anti-clogging nozzle 17 in a normally closed state, opening the output channel only when liquid or gas is introduced, effectively preventing nozzle clogging.

[0027] Working principle; Cleaning excess slurry: Turn on the control valve 6 of water pump 8 and clean water tank 3, and the liquid conveying mechanism 2 delivers clean water to rotating pipe 10; start bidirectional motor 13 to drive rotating pipe 10 to rotate back and forth within the range of 0-170°, and anti-clogging nozzle 17 sprays clean water at multiple angles to help the container 1 discharge excess slurry. Cleaning the coagulated slurry: Close the control valve 6 of the clean water tank 3 and open the control valve 6 of the dissolving tank 4. The liquid delivery mechanism 2 delivers cleaning agent to the rotating pipe 10. The cleaning agent is sprayed onto the inner wall of the container 1 through the anti-clogging nozzle 17, reacting with the coagulated slurry (reaction time 10-15 minutes) and breaking down the coagulated structure. The control valves allow for switching between clean water and cleaning agent, enabling different stages of cleaning to be completed without disassembling the equipment. Flushing and Drainage: Reopen the control valve 6 of the clean water tank 3 to supply clean water to flush the inner wall of the container 1 and remove any residues from the reaction. After stopping the liquid supply, turn on the air pump 7 to supply high-pressure gas to the rotating tube 10. This serves two purposes: firstly, to expel any residual liquid inside the rotating tube 10 (to prevent corrosion of components), and secondly, to flush the inside of the anti-clogging nozzle 17 to ensure unobstructed operation. The air pump 7 assists in draining the liquid to prevent residual liquid corrosion, extending the service life of the container 1 and the rotating tube 10 by 1.5 times.

[0028] Of course, the above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
