[0014] 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.

[0015] Existing bentonite deep processing filter sand purification equipment typically extracts fine montmorillonite particles from bentonite slurry, requiring secondary filtration to remove these particles. This increases production costs and reduces the efficiency of bentonite filter sand purification.

[0016] In view of this, the present invention provides a filter sand purification device for deep processing of bentonite. This device, through the cooperation of a second chamber, a discharge pipe, a second auger, a first filter plate, a connecting pipe, and a water pump, achieves the following effect when extracting mud and sand from bentonite slurry: the second chamber stores the extracted mud and sand, the second auger compresses the mud and sand, the first filter plate filters the mud and sand, and the filtered bentonite slurry enters a third chamber through the connecting pipe. The water pump then transports the bentonite slurry from the third chamber to the first chamber. This allows for solid-liquid separation of the extracted mud and sand containing bentonite slurry, with the separated bentonite slurry directly entering the first chamber without the need for secondary filtration of the bentonite slurry in the mud and sand, thereby reducing production costs and improving the efficiency of filter sand purification.

[0017] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly introduced below.

[0018] Example 1, by Figure 1-4 It is understood that the bentonite deep processing filter sand purification device in this case includes a base plate 1, a first box 2 is arranged above the base plate 1, a first auger 3 is rotatably connected to the inner wall of the first box 2 through a sealed bearing, and an extrusion device is arranged below the first auger 3. The extrusion device includes a second box 4, a discharge pipe 5, a second auger 6, a first filter plate 7, a connecting pipe 8 and a water pump 10. The second box 4 is fixedly connected to the bottom side of the first box 2. The discharge pipe 5 connects the second box 4 and the first box 2. The second auger 6 is arranged inside the second box 4. The second auger 6 passes through the second box 4 through a sealed bearing and extends to the outside of the second box 4. The first filter plate 7 is fixedly connected to the inner wall of the second box 4 away from the second auger 6. The connecting pipe 8 is connected to the side of the second box 4 away from the second auger 6. The other end of the connecting pipe 8 is connected to the water pump 10. The output end of the water pump 10 is connected to the bottom of the first box 2. In the specific implementation process, it is worth noting that the base plate 1 is made of cast iron or carbon steel to ensure that it can provide stable support for the entire bentonite deep processing sand purification device. The first housing 2 is made of stainless steel, which has high corrosion resistance and high oxidation resistance to ensure that it will not be easily corroded. The first filter plate 7 has a double-layer composite structure. The upper layer is a filter screen with a larger pore size to intercept larger coarse sand particles; the lower layer is a filter screen with a smaller pore size to filter smaller fine sand particles. The two layers of filter screens are fixed by a frame to form a stepped filtration structure, which improves the interception effect of sand. The first filter plate 7 consists of a filter screen with a larger pore size and a filter screen with a smaller pore size. The filter screen with a larger pore size filters larger sand particles, and the filter screen with a smaller pore size filters smaller particles in the sand. The water pump 10 is model B50-32-125 horizontal. A single-stage centrifugal pump ensures that pump 10 can meet the requirements for conveying bentonite slurry. Through the cooperation between the second housing 4, discharge pipe 5, second auger 6, first filter plate 7, connecting pipe 8 and pump 10, the extracted mud and sand enter the second housing 4 through discharge pipe 5. The second auger 6 contacts the mud and sand and conveys the mud and sand to the side of the second housing 4 away from the second auger 6. The mud and sand are subjected to the pressure of continuous conveying of mud and sand and the resistance of the first filter plate 7, which realizes the squeezing of mud and sand. The bentonite slurry enters the connecting pipe 8 through the first filter plate 7 and enters the pump 10 through the connecting pipe 8. The pump 10 conveys the bentonite slurry, which can squeeze out the bentonite slurry from the mud and sand and convey the squeezed bentonite slurry into the interior of the first housing 2. There is no need to filter the extracted mud and sand again, which is beneficial to improving the efficiency of bentonite slurry filtration and purification. Furthermore, a sand discharge device is provided at the bottom of the second housing 4. The sand discharge device includes a sealing cover 11, a connecting rod 12, a limiting plate 13, and a groove 14. The sealing cover 11 is rotatably connected to the bottom of the second housing 4 by a pin and fits against the bottom of the first filter plate 7. The connecting rod 12 is fixedly connected to one side of the bottom of the sealing cover 11. The side of the connecting rod 12 away from the sealing cover 11 fits against the bottom of the second housing 4. The limiting plate 13 is sleeved on the side of the outer wall of the connecting rod 12 away from the sealing cover 11. The top of the limiting plate 13 is slidably engaged with the groove 14 opened at the bottom of the second housing 4. In the specific implementation process, it is worth noting that a sealing gasket is fixedly connected between the sealing cover 11 and the second housing 4. The sealing gasket seals the gap between the sealing cover 11 and the second housing 4. One side of the connecting rod 12 is a cylinder with a larger diameter, and the other side is a cylinder with a smaller diameter. A limiting plate 13 is fitted onto the outer wall of the smaller diameter cylinder. The surface of the limiting plate 13 has a through hole, the size of which matches the diameter of the connecting rod 12, ensuring that the limiting plate 13 can slide on the surface of the connecting rod 12. To prevent jamming when the limiting plate 13 and the groove 14 slide, a ball bearing can be installed between the top of the limiting plate 13 and the groove 14. This converts the sliding friction between the limiting plate 13 and the groove 14 into rolling friction, maximizing the sliding friction between the limiting plate 13 and the groove 14. The smooth sliding between the grooves 14 is achieved by a handle fixedly connected to the bottom of the limiting plate 13. Through the cooperation between the sealing cover 11, the connecting rod 12, the limiting plate 13 and the grooves 14, the worker first places a storage box or other storage device at the bottom of the sealing cover 11, and then moves the limiting plate 13 by using the handle. The limiting plate 13 releases the limiting of the connecting rod 12. The worker rotates the sealing cover 11 away from the first box 2 with the pin as the center. The sealing cover 11 drives the first filter plate 7 away from the inside of the second box 4. The squeezed mud and sand fall into the storage device below under the action of gravity. After completion, the worker cleans the first filter plate 7 with a brush or other tools according to the actual use. This is beneficial for the treatment of the squeezed mud and sand and also facilitates the cleaning of the first filter plate 7. Furthermore, a protective shell 15 is fixedly connected to the side of the first housing 2 and the second housing 4 away from the water pump 10. A motor 16 is fixedly connected to the outer wall of the protective shell 15 away from the water pump 10 by bolts. The output end of the motor 16 passes through the second housing 4 through a sealed bearing and is fixedly connected to the end of the first auger 3 away from the water pump 10. Pulleys 17 are fixedly connected to the outer wall of the first auger 3 inside the protective shell 15 and the second auger 6 inside the protective shell 15. A belt 18 is connected between the two pulleys 17 for transmission. In the specific implementation process, it is worth noting that the protective shell 15 prevents the worker's limbs or clothing from getting caught in the pulley 17, causing a safety accident, and protects the pulley 17 and belt 18 from external debris entering between the pulley 17 and belt 18 and damaging them. The model of the motor 16 is not specifically limited, as long as it meets the actual use and work requirements. The power supply to the motor 16 is switched on and off by an external push switch, thereby driving the motor 16 to start. Through the cooperation between the protective shell 15, the motor 16, the pulley 17 and the belt 18, the motor 16 is first connected to the external power supply. The motor 16 drives the pulley 17 to rotate, the pulley 17 drives the belt 18 to rotate, and the belt 18 drives the pulley 17 below to rotate, thereby driving the second auger 6 to rotate, thus realizing the driving of the second auger 6. Example 2, by Figure 1-4 It can be seen that the first auger 3 is rotatably connected to the second filter plate 19 on the side away from the motor 16 through a sealed bearing, the top of the first housing 2 is provided with a feed inlet 20 on the side away from the protective shell 15, and the bottom of the first housing 2 is connected with a discharge outlet 21 on the side away from the motor 16. In the specific implementation process, it is worth noting that the material of the second filter plate 19 is polyethylene to ensure that the second filter plate 19 will not be easily corroded. The mesh size of the second filter plate 19 is not specifically limited, as long as it meets the actual use requirements. The bentonite slurry to be filtered and purified is introduced into the first box 2 through an external conveying device. The motor 16 drives the first auger 3 to rotate. The first auger 3 conveys the mud and sand in the bentonite slurry to the top of the discharge pipe 5. The liquid in the bentonite slurry enters the side of the first box 2 near the discharge port 21 through the second filter plate 19 and is discharged through the discharge port 21. Furthermore, a rotating column 22 is fixedly connected to the top of the base plate 1 near the water pump 10. The top of the rotating column 22 is rotatably connected to the bottom of the first box 2 via a pin. The bottoms of the first box 2 and the second box 4 are both rotatably connected to telescopic rods 9 via pins. Both telescopic rods 9 are rotatably connected to the top of the base plate 1 via pins. In the specific implementation process, it is worth noting that the telescopic rod 9 is an RM-PPLA type electric actuator. Two telescopic rods 9 are set at the bottom of the first housing 2 and the second housing 4. The two telescopic rods 9 at the bottom of the first housing 2 are controlled by a dedicated synchronous controller, and the two telescopic rods 9 at the bottom of the second housing 4 are controlled by a dedicated synchronous controller, so that a difference is formed between the two telescopic rods 9 at the bottom of the first housing 2 and the two telescopic rods 9 at the bottom of the second housing 4. By telescopically extending and retracting asynchronously, the angle of the first housing 2 is changed. Through the cooperation between the rotating column 22 and the telescopic rod 9, the telescopic rod 9 is first connected to an external power supply. When it is necessary to adjust the angle of the first housing 2, the telescopic rods 9 at the bottom of the second housing 4 and the telescopic rods 9 at the bottom of the first housing 2 extend and retract first. In this way, the first housing 2 can be rotated around the top of the rotating column 22 as the center, thereby realizing the adjustment of the tilt angle of the first housing 2. 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.
