Description

Technical Field

[0001] This utility model relates to the field of refined cotton alkali immersion technology, specifically a refined cotton alkali immersion and impurity removal device. Background Technology

[0002] Refined cotton is a white, flocculent substance made from cotton linters through processes such as alkali soaking, alkali cooking, bleaching, milling to remove water, and air drying. It is the basic material of cotton cellulose.

[0003] In the prior art, CN218373005U discloses a device for removing impurities from refined cotton by pre-impregnation with alkali. This patented technology removes impurities from refined cotton by vibration. However, since impurities have strong adhesion and refined cotton is prone to clumping, impurities are easily trapped inside the refined cotton. Vibration cannot effectively remove impurities. Therefore, we propose a device for removing impurities from refined cotton by pre-impregnation with alkali to solve this defect of the prior art. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a device for refining cotton by alkali impurity removal.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for refining cotton by alkali immersion and impurity removal includes an alkali immersion tank and an alkali storage tank. The alkali immersion tank is equipped with an isolation filter screen, and multiple hollow tubes are equidistantly arranged at the upper end of the isolation filter screen. Multiple exhaust heads are equidistantly arranged at the upper end of the hollow tubes. An air supply component is provided on the alkali immersion tank to supply air into the hollow tubes.

[0007] A hydraulic push rod is provided on the upper right side of the alkali leaching tank. A movable loading seat is provided at the push rod of the hydraulic push rod. Gears are rotatably provided on the front and rear ends of the lower end of the movable loading seat. A drive motor is provided at the upper end of the movable loading seat. The drive motor is connected to the center of one of the gears. A rubber gear transmission belt meshes between the gears. Multiple actuating rods are provided at equal intervals on the outside of the rubber gear transmission belt. The actuating rods are located inside the alkali leaching tank.

[0008] Multiple hollow tubes are installed between the upper and lower surfaces of the mobile loading base. The hollow tubes are located between the gears. A liquid suction tube is sealed and slidably installed inside the lower end of the hollow tube. A floating block is installed outside the bottom end of the liquid suction tube. A liquid extraction assembly is installed on the mobile loading base. The liquid extraction assembly is connected to the hollow tube to discharge floating impurities and alkaline solution into the alkaline solution storage tank.

[0009] The alkaline solution storage tank is equipped with a filter screen installed inside the partition. The outside of the alkali soaking tank is connected to a drain pipe, which is located at the lower end of the isolation filter screen and is connected to a switch control valve.

[0010] By adopting the above technical solution, the alkali solution and refined cotton are poured into the alkali soaking tank. The drive motor drives the gear to rotate, and the meshing of the gear and the rubber gear transmission belt drives the rubber gear transmission belt to rotate. When the rubber gear transmission belt rotates, it drives the actuating rod to rotate synchronously. In conjunction with the hydraulic push rod, it pushes the moving loading seat and the actuating rod to move laterally, so that the actuating rod disperses the refined cotton in the alkali solution, promotes the discharge of impurities, and improves the alkali soaking effect. This allows heavy impurities to fall through the isolation filter screen and settle to the bottom of the alkali soaking tank.

[0011] In addition, during the process of breaking up the refined cotton, air is supplied into the hollow tube through the air supply component and discharged through the exhaust head, so that the bubbles float in the alkaline solution, and the cleaned light impurities are adsorbed onto the surface of the bubbles and float to the surface of the alkaline solution.

[0012] During the movement of the mobile loading platform, the hollow tube and the suction tube slide together, and the floating block floats on the surface of the alkali solution. The suction component works and connects with the hollow tube, allowing the suction tube to draw out the surface alkali solution and impurities and discharge them into the alkali solution storage tank. This improves the impurity removal effect on the alkali-soaked refined cotton. The filter screen isolates impurities, and the filtered alkali solution is stored in the alkali solution storage tank. After alkali soaking is completed, the switch control valve is opened to discharge the alkali solution from the drain pipe into the alkali solution storage tank. The filter screen isolates impurities, and the filtered alkali solution is stored in the alkali solution storage tank, realizing the reuse of alkali solution.

[0013] As a preferred embodiment of this utility model, the air supply assembly includes a connecting pipe connecting the hollow tubes and a turbocharger fan located outside the alkali immersion tank. An exhaust pipe is connected to the exhaust port of the turbocharger fan, and the exhaust pipe is connected to the connecting pipe.

[0014] Using the above technical solution, the turbocharger blower works to discharge airflow. By utilizing the interconnection between the turbocharger blower, exhaust pipe, connecting pipe, hollow pipe and exhaust head, the airflow is discharged from the exhaust head and forms bubbles in the alkaline solution.

[0015] As a preferred embodiment of this utility model, the lower surface of the floating block is flush with the lower surface of the suction tube, and an isolation net is provided at the lower opening of the suction tube.

[0016] Using the above technical solution, the isolation net isolates the refined cotton, preventing the refined cotton from being drawn out of the suction tube.

[0017] As a preferred embodiment of this utility model, the liquid extraction assembly includes a straight pipe connected to the upper ends of the hollow tubes and a liquid extraction pump located on the upper end of the mobile loading seat. A liquid extraction pipe is connected between the liquid extraction port of the liquid extraction pump and the straight pipe, and a spring hose is connected to the liquid extraction port of the liquid extraction pump. The other end of the spring hose is connected to a liquid discharge head, which is located above the alkali storage tank and connected to the alkali leaching tank.

[0018] Using the above technical solution, the pump operates, and by utilizing the interconnection between the pump, the suction pipe, the straight pipe, the hollow pipe, the suction pipe, the spring hose and the discharge head, the surface alkaline solution and impurities are drawn in from the suction pipe and discharged into the alkaline solution storage tank through the discharge head.

[0019] The elastic extension and contraction of the spring hose allows for the movement of the mobile loading seat.

[0020] As a preferred embodiment of this utility model, the alkaline storage tank is externally connected to an outlet pipe, which is located at the lower end of the filter screen, and an automatic switching valve is externally connected to the outlet pipe.

[0021] By adopting the above technical solution, opening the automatic switch valve allows the filtered alkali solution stored in the alkali solution storage tank to be discharged through the outlet pipe, thus realizing the reuse of the alkali solution.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] The refined cotton is dispersed by the lever to promote the separation of impurities and discharge them, thereby improving the alkali soaking effect. Heavy impurities fall through the isolation filter and settle to the bottom of the alkali soaking tank.

[0024] By supplying air through the air supply component, bubbles float to the surface of the alkaline solution, causing light impurities to be adsorbed onto the surface of the bubbles and float to the surface of the alkaline solution, which is conducive to the removal of impurities.

[0025] By moving the loading platform, a floating block floats on the surface of the alkali solution. The surface alkali solution and impurities are extracted by the suction pipe and discharged into the alkali solution storage tank. The filter screen isolates the impurities, and the filtered alkali solution is stored in the alkali solution storage tank. After the alkali leaching is completed, the alkali solution is discharged into the alkali solution storage tank and filtered again by the filter screen, so as to realize the reuse of the alkali solution.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1 to 3 The refined cotton alkali immersion and impurity removal device in this embodiment mainly includes an alkali immersion tank 1, an alkali storage tank 2, an air supply component, an actuation component, a liquid extraction component, and related control components.

[0032] The alkali soaking tank 1 is rectangular in shape and made of stainless steel, which has good corrosion resistance and strength. An isolation filter 3 is installed and fixed inside the tank. The isolation filter 3 is a fine metal mesh that can isolate the refined cotton. It is installed horizontally inside the alkali soaking tank 1 to divide the tank 1 into upper and lower parts. The upper part is used to place the refined cotton and alkali solution for alkali soaking, and the lower part is used to settle heavy impurities.

[0033] The alkali storage tank 2 is also rectangular in shape and made of the same material as the alkali soaking tank 1. It is located on its side and is used to store the filtered alkali solution. A filter screen 20 is installed and fixed inside the alkali storage tank 2. The filter screen 20 has a multi-layer metal filter structure, which can effectively filter impurities in the alkali solution. The left side of the alkali soaking tank 1 is connected to a drain pipe 18. The drain pipe 18 is located at the lower end of the isolation filter screen 3, and the drain pipe 18 is connected to a switch control valve 19. The switch control valve 19 is an electric valve and can be controlled to open and close by the control system. The left side of the alkali storage tank 2 is connected to an outlet pipe 21. The outlet pipe 21 is located at the lower end of the filter screen 20, and the outlet pipe 21 is connected to an automatic switch valve 22, which is also an electric valve.

[0034] Inside the alkali soaking tank 1, multiple hollow tubes 4 are fixed horizontally at equal intervals on the upper surface of the isolation filter screen 3. The number of hollow tubes 4 is 5-10. Multiple exhaust heads 5 are connected at equal intervals on the upper surface of each hollow tube 4. The number of exhaust heads 5 is 10-20. The exhaust heads 5 are small nozzle structures that allow gas to be evenly discharged into the alkali solution.

[0035] The alkali leaching tank 1 is equipped with an air supply component.

[0036] The gas supply assembly is used to supply gas into the hollow tube 4 to form bubbles to help impurities float. The gas supply assembly includes a connecting pipe 6 connecting the hollow tubes 4 and a turbocharger 7 fixed to the outside of the left side of the alkali leaching tank 1. The turbocharger 7 is a common industrial fan with a large air volume and stable pressure output. The exhaust port of the turbocharger 7 is connected to an exhaust pipe 8, which is connected to the connecting pipe 6. When the turbocharger 7 works, the air is compressed and passes through the exhaust pipe 8, the connecting pipe 6, and the hollow tube 4 in sequence, and is finally discharged from the exhaust head 5, forming bubbles in the alkali solution.

[0037] When pouring alkali solution into the alkali soaking tank 1, it is necessary to ensure that the alkali solution level is lower than that of the turbocharger fan 7.

[0038] Toggle component

[0039] The agitator is used to disperse the refined cotton in the alkali soaking tank 1, promoting the discharge of impurities. A hydraulic push rod 9 is fixed to the upper right surface of the alkali soaking tank 1. The hydraulic push rod 9 is an electro-hydraulic push rod, and a movable loading seat 10 is fixed at the push rod. The movable loading seat 10 is a rectangular plate structure, with gears 11 rotating circumferentially on both the front and rear ends of its lower surface. A drive motor 12 is fixed to the upper surface of the movable loading seat 10. The drive motor 12 is a servo motor with precise speed control capability. The output shaft of the drive motor 12 is connected and fixed to the center of the front gear 11. A rubber gear transmission belt 13 meshes with the outer surfaces of the gears 11. The inner surface of the rubber gear transmission belt 13 is fixed with gears 11 at equal intervals. The toothed blocks with meshing teeth and the rubber gear transmission belt 13 have a certain degree of elasticity, which can reduce noise and wear during transmission. Multiple actuating rods 14 are fixed at equal intervals on the outside of the rubber gear transmission belt 13. The number of actuating rods 14 is 10-20. The actuating rods 14 are cylindrical and located inside the alkali soaking tank 1. When the drive motor 12 starts, it drives the gear 11 connected to it to rotate. Through the meshing transmission between the gear 11 and the rubber gear transmission belt 13, the rubber gear transmission belt 13 rotates, which in turn drives the actuating rods 14 to rotate synchronously. At the same time, the hydraulic push rod 9 pushes the moving loading seat 10 to move laterally, so that the actuating rods 14 can move laterally during rotation, and disperse the refined cotton in the alkali solution in all directions.

[0040] A liquid extraction assembly is provided on the mobile loading base 10, and the liquid extraction assembly is connected to the hollow tube 15.

[0041] The liquid extraction assembly is used to extract floating debris and alkali solution from the inner surface of the alkali soaking tank 1 into the alkali solution storage tank 2. Multiple hollow tubes 15, numbering 4-6, are fixedly connected between the upper and lower surfaces of the mobile loading base 10. The hollow tubes 15 are located between gears 11. A suction tube 16, a slender tubular structure, is sealed and slidably mounted inside the lower end of each hollow tube 15. A floating block 17, made of foam material, is fixed to the outside of its bottom end and floats on the alkali solution surface. The lower surface of the floating block 17 is flush with the lower surface of the suction tube 16. A separator mesh, made of stainless steel, is fixed to the lower opening of the suction tube 16 to prevent refined cotton quilts from being sucked into the suction tube 16. The liquid extraction assembly includes a straight tube 23 connecting the upper ends of the hollow tubes 15 and a component fixed to the upper end of the mobile loading base 10. The surface pump 24 is a common industrial pump with sufficient pumping capacity. The pump port 24 is connected to the straight pipe 23 by a pumping pipe 25. The pump outlet 24 is connected to a spring hose 26, which has a certain elasticity and can meet the movement stroke of the mobile loading seat 10. The other end of the spring hose 26 is connected to a drain head 27, which is located above the alkali storage tank 2 and is fixedly connected to the alkali soaking tank 1. When the pump 24 is working, the interconnection between the pump 24, the pumping pipe 25, the straight pipe 23, the hollow pipe 15, the suction pipe 16, the spring hose 26 and the drain head 27 allows the surface alkali and impurities to be sucked in from the suction pipe 16 and discharged into the alkali storage tank 2 through the drain head 27.

[0042] It should be added that when the movable loading seat 10 is located on the far right, the spring hose 26 is in a fully extended state.

[0043] The device of this utility model is equipped with a control system, which adopts a programmable logic controller (PLC). The control system is electrically connected to components such as the turbocharger fan 7, drive motor 12, hydraulic push rod 9, liquid pump 24, switch control valve 19 and automatic switch valve 22. Through the preset program, the control system can accurately control the working time and working status of each component.

[0044] Usage steps,

[0045] Preparation stage: Pour the refined cotton and alkali solution into the alkali soaking tank 1, so that the refined cotton is completely immersed in the alkali solution.

[0046] Alkali soaking and impurity removal stage:

[0047] The control system is started. The control system first starts the turbocharger fan 7. The turbocharger fan 7 compresses the air and then passes it through the exhaust pipe 8, the connecting pipe 6, and the hollow pipe 4 in sequence, and then discharges it from the exhaust head 5. Bubbles are formed in the alkaline solution, which causes light impurities to be adsorbed onto the surface of the bubbles and float to the surface of the alkaline solution.

[0048] Simultaneously, the control system starts the drive motor 12 and the hydraulic push rod 9. The drive motor 12 drives the gear 11 connected to it to rotate. Through the meshing transmission of the gear 11 and the rubber gear transmission belt 13, the rubber gear transmission belt 13 rotates, driving the actuating rod 14 to rotate synchronously. The hydraulic push rod 9 pushes the moving loading seat 10 to move laterally, so that the actuating rod 14 can move laterally during the rotation, which disperses the refined cotton in the alkali solution and promotes the heavy impurities to fall through the isolation filter screen 3 and settle to the bottom of the alkali soaking tank 1.

[0049] During the stirring process, the float 17 always floats on the surface of the alkali solution, causing the suction pipe 16 to slide inside the hollow tube 15, so that the suction pipe 16 is always on the surface of the liquid. The control system starts the pump 24 at regular intervals. The pump 24 draws out the surface alkali solution and impurities through the suction pipe 25, straight pipe 23, hollow tube 15 and suction pipe 16, and discharges them into the alkali solution storage tank 2 through the spring hose 26 and the drain head 27. The filter screen 20 in the alkali solution storage tank 2 filters the incoming alkali solution and isolates impurities.

[0050] Drainage stage: After the alkali immersion is completed, the control system opens the switch control valve 19, and the alkali solution in the alkali immersion tank 1 is discharged into the alkali solution storage tank 2 through the drain pipe 18. The filter screen 20 filters the alkali solution again, so that the filtered alkali solution is stored in the alkali solution storage tank 2.

[0051] Alkali reuse stage: When alkali needs to be reused, the control system opens the automatic switch valve 22, and the filtered alkali stored in the alkali storage tank 2 is discharged through the outlet pipe 21 for subsequent production use.

[0052] Beneficial effects

[0053] This invention relates to a device for removing impurities from refined cotton through alkali impregnation. A stirring component disperses the refined cotton within the alkali impregnation tank, while air bubbles generated by an air supply component cause impurities to float to the surface. A liquid extraction component then draws the surface impurities and alkali solution into an alkali storage tank for filtration, effectively improving the impurity removal efficiency for the alkali-impregnated refined cotton. Simultaneously, the installation of an isolation filter and a filter screen enables the separation of heavy and light impurities, as well as the reuse of the alkali solution, reducing production costs and increasing production efficiency.

[0054] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control functions, and the existing publicly available power connection technologies are not described in detail in the text.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
