Description

Technical Field

[0001] This utility model relates to the field of kaolin technology, specifically to a kaolin raw material filtration, stirring and sedimentation tank. Background Technology

[0002] Kaolin, with the theoretical chemical formula Al2[(OH)4 / Si2O5], is a non-metallic mineral. It is a type of clay and clay rock mainly composed of kaolinite group clay minerals. Because of its white and fine appearance, it is also known as dolomite.

[0003] In the process of filtering kaolin, it is often necessary to first use a filtration device to perform preliminary filtration. After the kaolin is pre-filtered, it is added to the inside of a mixing device and mixed with dispersants, flocculants, and pH adjusters to remove fine impurities from the soil. After the mixing is completed, it is transported to a sedimentation tank or sedimentation chamber for sedimentation. Some existing kaolin filtration equipment integrates preliminary filtration, reagent mixing, and sedimentation into one device design, which can significantly improve production efficiency and resource utilization. This integrated device can be called a kaolin raw material filtration, mixing, and sedimentation device.

[0004] However, existing integrated kaolin raw material filtration, mixing, and sedimentation equipment initially filters out large impurities such as stones mixed in the soil by adding a filter screen inside the feed pipe. But as the equipment is used for a longer period of time, more and more impurities accumulate on the filter screen. Excessive impurities will affect the filtration operation of the filter screen, and when there are too many impurities, the machine needs to be stopped to clean the impurities on the filter screen. This situation affects the kaolin filtration efficiency of the equipment. Therefore, it does not meet the existing requirements. In response, we have proposed a kaolin raw material filtration, mixing, and sedimentation tank. Utility Model Content

[0005] The purpose of this utility model is to provide a kaolin raw material filtration, stirring and sedimentation tank to solve the problems mentioned in the background art. The existing kaolin raw material filtration, stirring and sedimentation equipment integrates three functions and initially filters out large impurities such as stones mixed in the soil by adding a filter screen inside the feed pipe. However, as the equipment is used for a longer period of time, more and more impurities accumulate on the filter screen. Excessive impurities will affect the filtration operation of the filter screen. When there are too many impurities, it is necessary to stop the machine to clean the impurities on the filter screen. This situation affects the kaolin filtration efficiency of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a kaolin raw material filtration, stirring, and sedimentation tank, comprising a stirring tank, a concave support fixed to the upper end face of the stirring tank, a stepper motor fixedly installed at the middle position of the upper end face of the concave support, the output shaft of the stepper motor connected to a threaded rod via a coupling, an internal threaded sleeve installed on the lower side of the outer surface of the threaded rod via a threaded structure, a connecting rod fixed to the front and rear end faces of the internal threaded sleeve, a sealing sleeve fixed to the outer side of the two connecting rods, the outer surface of the sealing sleeve fitting against the inner wall of the top end of the stirring tank, a slide rail provided at the front and rear of the sealing sleeve, a slider slidably installed on one side inside the slide rail, the slider facing the sealing sleeve being fixed to the sealing sleeve, and a discharge port provided below the slider;

[0007] Below the concave support is an arc-shaped conical filter screen fixed to the upper side of the inside of the mixing tank.

[0008] Preferably, an arc-shaped conical support molding head is provided below the arc-shaped conical filter screen. The arc-shaped conical support molding head is generally arc-shaped, and the upper end face of the arc-shaped conical support molding head is in contact with the lower end face of the arc-shaped conical filter screen.

[0009] Preferably, an impurity discharge pipe is fixed on the upper side of both the front and rear end faces of the mixing tank, and the two discharge ports are respectively connected to the interior of the two impurity discharge pipes.

[0010] Preferably, a valve pipe is fixed to the lower end face of the mixing tank, a sedimentation tank is fixed to the lower end face of the valve pipe, and a control panel is fixedly installed on one side of the outer surface of the sedimentation tank.

[0011] Preferably, a mixing and stirring mechanism is installed inside the mixing tank below the arc-shaped conical support plastic head, and the valve pipe, sedimentation tank, stepper motor and mixing and stirring mechanism are all electrically connected to the control panel.

[0012] Preferably, the lower end face of the threaded rod is fixed with an anti-detachment circular plate, and the cross-sectional diameter of the anti-detachment circular plate is larger than the cross-sectional diameter of the internal threaded sleeve.

[0013] Preferably, a support rod is fixed to the lower side of both the front and rear ends of the arc-shaped conical support plastic head, and the other end of the support rod is fixed to the inner wall of the mixing tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model features a discharge port sealed by a sealing sleeve on both the front and back of an arc-shaped conical filter screen located on the upper side inside the mixing tank for filtration. After the equipment finishes its daily work and no more kaolin raw materials are added to the mixing tank, the sealing sleeve is moved upward by a stepper motor to open the discharge port. The equipment continues to run for ten minutes. During these ten minutes, large impurities on the upper surface of the arc-shaped conical filter screen will roll into the discharge port due to the vibration of the equipment during operation, thus completing the discharge of large impurities. The above technical solution can automatically clean the impurities accumulated on the upper surface of the arc-shaped conical filter screen, thereby improving the functionality of the equipment.

[0016] 2. In this utility model, during the normal operation of the equipment, the discharge port used for large impurity discharge is sealed by a sealing sleeve. By sealing the discharge port during normal operation of the equipment, it is possible to prevent the kaolin raw material from being discharged along with it. The above technical solution can prevent some kaolin raw material from entering the discharge port and thus preventing the waste of kaolin raw material. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The mixing tank 1 (model GH-304JBJ-ZW), valve pipe 2 (model CBF-001), and stepper motor 6 (model DM542) mentioned in this utility model can be obtained from the market or through private customization.

[0024] Please see Figures 1 to 4 An embodiment of this utility model provides a kaolin raw material filtration, stirring, and sedimentation tank, including a stirring tank 1. A concave support 5 is fixed on the upper end face of the stirring tank 1. A stepper motor 6 is fixedly installed at the middle position of the upper end face of the concave support 5. The output shaft of the stepper motor 6 is connected to a threaded rod 8 through a coupling. An internal threaded sleeve 9 is installed on the lower side of the outer surface of the threaded rod 8 through a threaded structure. A connecting rod 10 is fixed on both the front and rear ends of the internal threaded sleeve 9. A sealing sleeve 11 is fixed on the outer side of the two connecting rods 10. The outer surface of the sealing sleeve 11 is in contact with the inner wall of the top end of the stirring tank 1. A slide rail 13 is provided at both the front and rear sides of the sealing sleeve 11. A slider 14 is slidably installed on one side inside the slide rail 13. The surface of the slider 14 facing the sealing sleeve 11 is fixed to the sealing sleeve 11. A discharge port 12 is provided below the slider 14.

[0025] Below the concave bracket 5, an arc-shaped conical filter screen 7 is fixed to the upper side of the inside of the mixing tank 1; below the arc-shaped conical filter screen 7, an arc-shaped conical support plastic head 15 is provided, the arc-shaped conical support plastic head 15 is entirely arc-shaped conical, and the upper end face of the arc-shaped conical support plastic head 15 is in contact with the lower end face of the arc-shaped conical filter screen 7; a valve pipe 2 is fixed to the lower end face of the mixing tank 1, a sedimentation tank 3 is fixed to the lower end face of the valve pipe 2, and a control panel is fixedly installed on one side of the outer surface of the sedimentation tank 3; below the arc-shaped conical support plastic head 15, a mixing and stirring mechanism is installed inside the mixing tank 1. Furthermore, valve pipe 2, sedimentation tank 3, stepper motor 6, and mixing and stirring mechanism are all electrically connected to the control panel. When the equipment needs to be used, the mixing and stirring mechanism is started through the control panel, and then kaolin raw material is added into the mixing tank 1. The kaolin raw material poured into the mixing tank 1 will first come into contact with the arc-shaped conical filter screen 7 fixed on the upper side of the mixing tank 1. The vibration of the mixing and stirring mechanism during operation enables the arc-shaped conical filter screen 7 to automatically filter the kaolin raw material falling on its upper surface, thereby blocking large impurities on the upper surface of the arc-shaped conical filter screen 7.

[0026] The kaolin raw material that has been filtered by the arc-shaped conical filter screen 7 will come into contact with the mixing and stirring mechanism located inside the mixing tank 1. After the two come into contact, water, dispersant, flocculant and pH adjuster are added inside the mixing tank 1 to remove fine impurities in the kaolin raw material.

[0027] After the mixing operation is completed, valve pipe 2 is opened. When valve pipe 2 is opened, the kaolin raw material mud formed by the mixed water source will fall into the sedimentation tank 3 through valve pipe 2 for sedimentation treatment. After the sedimentation treatment is completed, the sewage is pumped out and the kaolin raw material mud is made into mud cakes. The water in the mud cakes is removed by sunlight or drying equipment to make kaolin.

[0028] An impurity discharge pipe 4 is fixed on the upper side of both the front and rear ends of the mixing tank 1, and the two discharge ports 12 are respectively connected to the interior of the two impurity discharge pipes 4. When the equipment finishes its work for a day and no more kaolin raw materials are added to the mixing tank 1, the stepper motor 6 is started, and the threaded rod 8 connected to it can be driven to rotate through the stepper motor 6.

[0029] Since a slider 14 is fixed to both the front and rear ends of the sealing sleeve 11 and is slidably installed inside the slide rail 13, neither the sealing sleeve 11 nor the internal threaded sleeve 9 connected to the sealing sleeve 11 by the connecting rod 10 can rotate.

[0030] When the threaded rod 8 rotates, the internal threaded sleeve 9, which is threadedly connected to it but cannot rotate on its own, will move up and down accordingly. When the internal threaded sleeve 9 moves upward, the sealing sleeve 11, which is indirectly connected to it, will also move upward. As the sealing sleeve 11 rises, the discharge port 12, which is sealed by the sealing sleeve 11, will be gradually opened. After the discharge port 12 is opened, the mixing and stirring mechanism is run for ten minutes. During these ten minutes, large impurities located on the upper surface of the arc-shaped conical filter screen 7 will roll into the discharge port 12 along the upper surface of the arc-shaped conical filter screen 7 due to the vibration of the mixing and stirring mechanism during operation. They will then enter the impurity discharge pipe 4 through the discharge port 12 to complete the discharge of large impurities. After the mixing and stirring mechanism has run for ten minutes, the mixing and stirring mechanism is turned off, and the sealing sleeve 11 is moved downward by the stepper motor 6 to seal the discharge port 12 again.

[0031] The above technical solution can automatically clean the impurities accumulated on the upper surface of the arc-shaped conical filter screen 7, thereby improving the functionality of the equipment. During normal operation, the discharge port 12 used for large impurity discharge is sealed by the sealing sleeve 11. By sealing the discharge port 12 during normal operation, it is possible to prevent some kaolin raw materials from entering the discharge port 12 and thus avoiding waste of kaolin raw materials.

[0032] A support rod is fixed to the lower side of both the front and rear ends of the arc-shaped conical support plastic head 15, and the other end of the support rod is fixed to the inner wall of the mixing tank 1. The support rod can support the arc-shaped conical support plastic head 15, and the arc-shaped conical support plastic head 15, whose upper end face is in contact with the lower end face of the arc-shaped conical filter screen 7, can plasticize the middle position of the arc-shaped conical filter screen 7, ensuring that the middle position to the edge position of the upper end face of the arc-shaped conical filter screen 7 is inclined. The arc-shaped conical support plastic head 15 can also prevent the arc-shaped conical filter screen 7 from being deformed by kaolin.

[0033] A circular anti-detachment plate is fixed to the lower end face of the threaded rod 8, and the cross-sectional diameter of the circular anti-detachment plate is larger than the cross-sectional diameter of the internal threaded sleeve 9; the circular anti-detachment plate can prevent the internal threaded sleeve 9 from falling off the outer surface of the threaded rod 8.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
