A bentonite purification device

Abstract

This utility model relates to the field of bentonite purification technology and discloses a bentonite purification device, including a box shell with a discharge port on one side, a U-shaped connecting groove inside the box shell, and a square groove inside the box shell. Multiple sets of connecting pipes (first type) are passed through the lower end of the square groove, and multiple sets of connecting pipes (second type) are opened inside the box shell. A vibrating screen assembly is fixedly installed at the upper end of the box shell. When bentonite slurry enters the box from the inlet, the filter screen performs preliminary screening. At this time, the vibrating screen assembly is activated: an electric telescopic rod drives the extrusion plate to move up and down reciprocally within the square groove, and the lower anti-blocking cone slides out from the first connecting pipe to prevent blockage at the discharge port. On the other hand, the extrusion plate draws gas from the U-shaped connecting groove, and through air pressure transmission, drives the connecting rod (second type) to slide within the second connecting pipe, causing the U-shaped plate to vibrate up and down in conjunction with the filter screen. During vibration, impurities roll down the inclined surface to the discharge port, preventing mesh blockage.

Description

Technical Field

[0001] This utility model relates to the field of bentonite purification technology, and in particular to a bentonite purification device. Background Technology

[0002] Bentonite is a non-metallic mineral with montmorillonite as its main mineral component. It has excellent properties such as adsorption and expansion and is widely used in many fields. However, in addition to montmorillonite, natural bentonite ore also contains various impurities such as calcite, illite, quartz and mica. Furthermore, due to differences in its formation and mineralization environment, the quality of bentonite varies greatly. Even different sections of the same ore have different compositions and relative contents. With the development of industry, the demand for bentonite is increasing day by day, and high-quality bentonite is gradually being depleted. Medium and low-grade bentonite has become the main raw material available at present. In order to meet the requirements of various industries for the purity and performance of bentonite and to produce products with stable quality, it is necessary to beneficiate and purify the raw ore to obtain bentonite raw materials with stable montmorillonite content.

[0003] For example, Chinese patent CN209302978U discloses a high-efficiency bentonite processing and purification device. The raw material is put into the feed inlet and enters the rotating drum. After the raw material enters the drum, the raw material is processed and purified. After the raw material flows out from the distribution device, the waste residue is discharged from the slag outlet. By setting up a rotary pusher, the motor is started during the processing and purification of bentonite, which drives the rotary pusher to start rotating. This can effectively discharge the waste residue from the slag outlet, so that the device will not be affected by the blockage of the slag outlet. The remaining raw material is discharged from the discharge outlet. A cleaning device is set up to process and purify the bentonite in the device.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: During the filtration process, the filter screen of the bentonite purification device is often clogged due to the accumulation of impurities, which affects the filtration efficiency. In addition, the traditional vibration structure is difficult to act precisely on the inclined filter screen, resulting in large impurities not being discharged in time. At the same time, there is a lack of an efficient separation mechanism for impurities with different densities in the slurry, which easily causes the mixing and loss of montmorillonite particles and impurities with higher density, reducing the purification accuracy. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of impurity accumulation causing filter screen blockage and affecting filtration efficiency. To this end, we propose a bentonite purification device.

[0006] To achieve the above objectives, this application adopts the following technical solution: a bentonite purification device, including a purification box, the purification box including a box shell, an inlet at the upper end of the box shell, a support leg fixedly installed at the lower end of the box shell, a filter screen rotatably installed inside the box shell, and a discharge port on one side of the box shell. The filter screen is set at an angle of 5-8° with the ground. When the device is working, impurities enter the box shell through the inlet. Impurities with large particle size, high hardness, and high density cannot be separated because they cannot pass through the filter screen mesh. They fall into the discharge port and enter the waste residue collection device. The filtered slurry is then purified in the next step.

[0007] Preferably, a collection funnel is provided at the lower end of the filter screen, and an arc-shaped bend is fixedly installed at the lower end of the collection funnel. Multiple sets of protruding ribs are fixedly installed on the inner wall of the arc-shaped bend. The slurry after screening enters the arc-shaped bend. The protruding ribs at the bottom of the bend of the waterway will disturb the water flow, causing impurities with higher density to settle due to gravity, while montmorillonite, due to its fine particle size, is fully dispersed in the water medium and continues to move forward with the water flow. Finally, the slurry flows into the sedimentation tank, where the montmorillonite particles slowly settle to form a high-purity bentonite enrichment layer.

[0008] Preferably, the outer shell of the box has a U-shaped connecting groove inside and a square groove inside, which is connected to the U-shaped connecting groove. Multiple sets of connecting pipes are opened through the lower end of the square groove, and multiple sets of connecting pipes are opened inside the outer shell of the box, which are connected to the U-shaped connecting groove.

[0009] Preferably, a vibrating screen assembly is fixedly installed on the upper end of the outer shell of the box, and the vibrating screen assembly is matched with the square channel and the connecting pipe.

[0010] Preferably, the vibrating screen assembly includes an electric telescopic rod, the drive end of which is fixedly installed with a connecting rod, the connecting rod penetrating the outer shell of the box and fixedly installed with an extrusion plate, the extrusion plate matching the square channel, and multiple sets of anti-blocking cones fixedly installed at the lower end of the extrusion plate, the anti-blocking cones matching the connecting pipe.

[0011] Preferably, each of the multiple sets of connecting pipes 2 has a connecting rod 2 slidably installed inside. The upper end of the connecting rod 2 penetrates the outer shell of the box and is fixedly installed with a U-shaped plate. The U-shaped plate is located at the upper end of the discharge port and is slidably connected to the outer shell of the box. The upper end of the U-shaped plate is rotatably connected to the filter screen. Multiple sets of elastic elements are fixedly installed inside the U-shaped plate. One end of the elastic element is fixedly connected to the outer shell of the box. The elastic element is provided with a telescopic rod inside. The telescopic rod is fixedly connected to the inner wall of the U-shaped plate. After the slurry is screened by the device, impurities with large particle size, high hardness, and high density are separated through the mesh of the filter screen and fall to the upper end of the filter screen. At this time, the electric telescopic rod is activated to drive the connecting rod 1 and the squeezing plate and anti-blocking cone at its lower end to move up and down reciprocally. While the anti-blocking cone moves downward, it displaces the large pieces of impurities accumulated at the discharge port. The process involves clearing blockages to prevent large impurities from clogging the discharge port and reducing the filtration efficiency of the filter screen. Simultaneously, as the extrusion plate and anti-clogging cone move downwards, the extrusion plate draws gas from the U-shaped connecting channel. Since the gas volume inside the U-shaped connecting channel is fixed, the gas draw by the extrusion plate moves the connecting rod downwards, which in turn moves the U-shaped plate downwards. During the up-and-down movement of the extrusion plate, the U-shaped plate also moves up and down. Through the elastic element and telescopic rod at the lower end of the U-shaped plate, the filter screen, which is rotatably connected to the U-shaped plate, vibrates as it moves up and down. Because the filter screen is tilted, this vibration causes large impurities at the top of the screen to roll downwards along the tilt, ultimately falling through the discharge port into the waste collection device.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, when the bentonite slurry enters the box through the inlet, the filter screen first performs preliminary screening of the particles. Large-sized and high-density impurities cannot pass through the mesh and accumulate on the filter screen surface, while fine-particle slurry falls into the arc-shaped bend through the collection funnel. At this time, the vibrating screen assembly is activated: the electric telescopic rod drives the extrusion plate to move up and down in the square groove, and the lower anti-blocking cone is simultaneously inserted into the connecting pipe one. On the one hand, it clears the large impurities accumulated at the discharge port and prevents blockage; on the other hand, the extrusion plate draws the gas in the U-shaped connecting groove, and through air pressure transmission, it drives the connecting rod two to slide in the connecting pipe two, so that the U-shaped plate vibrates up and down in conjunction with the filter screen. Because the filter screen is set at an inclination, impurities roll down the inclined surface to the discharge port during vibration, avoiding mesh blockage. Attached Figure Description

[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] Reference Figure 1-3As shown, this utility model provides a technical solution: a bentonite purification device, including a purification box 1, the purification box 1 including a box shell 11, the upper end of the box shell 11 is provided with a feed inlet 12, the lower end of the box shell 11 is fixedly installed with a support leg 13, a filter screen 14 is rotatably installed inside the box shell 11, and a discharge port 111 is provided on one side of the box shell 11. The filter screen 14 is set at an angle of 5-8° with the ground. When the device is working, impurities enter the box shell 11 through the feed inlet 12. Impurities with large particle size, high hardness, and high density cannot be separated because they cannot pass through the mesh of the filter screen 14. They fall into the front discharge port 111 and enter the waste residue collection device. The filtered slurry is then purified in the next step.

[0027] Reference Figure 3-5 As shown in this embodiment: a collection funnel 15 is provided at the lower end of the filter screen 14, and an arc-shaped bend 16 is fixedly installed at the lower end of the collection funnel 15. Multiple sets of protruding ribs 161 are fixedly installed on the inner wall of the arc-shaped bend 16. The slurry after sieving enters the arc-shaped bend 16. The protruding ribs 161 at the bottom of the bend of the waterway will disturb the water flow, causing impurities with higher density to settle due to gravity. Meanwhile, montmorillonite, due to its fine particle size, is fully dispersed in the water medium and continues to move forward with the water flow. Finally, the slurry flows into the sedimentation tank, where the montmorillonite particles slowly settle to form a high-purity bentonite enrichment layer.

[0028] Reference Figure 6-7 As shown in this embodiment: a U-shaped connecting groove 112 is provided inside the outer shell 11 of the box, and a square groove 113 is provided inside the outer shell 11 of the box. The square groove 113 is connected to the U-shaped connecting groove 112. Multiple sets of connecting pipes 114 are provided through the lower end of the square groove 113. Multiple sets of connecting pipes 115 are provided inside the outer shell 11 of the box. The connecting pipes 115 are connected to the U-shaped connecting groove 112.

[0029] Reference Figure 6-7 As shown in this embodiment: a vibrating screen assembly 17 is fixedly installed on the upper end of the outer shell 11 of the box, and the vibrating screen assembly 17 is matched with the square channel 113 and the connecting pipe 114.

[0030] Reference Figure 6-8 As shown in this embodiment: the vibrating screen assembly 17 includes an electric telescopic rod 178, the drive end of the electric telescopic rod 178 is fixedly installed with a connecting rod 171, the connecting rod 171 passes through the outer shell 11 of the box and is fixedly installed with an extrusion plate 172, the extrusion plate 172 matches the square channel 113, and multiple sets of anti-blocking cones 173 are fixedly installed at the lower end of the extrusion plate 172, the anti-blocking cones 173 match the connecting pipe 114.

[0031] Reference Figure 6-9As shown in this embodiment: Connecting rods 174 are slidably installed inside multiple sets of connecting pipes 115. The upper end of the connecting rod 174 penetrates the outer shell 11 and is fixedly installed with a U-shaped plate 175. The U-shaped plate 175 is located above the discharge port 111 and is slidably connected to the outer shell 11. The upper end of the U-shaped plate 175 is rotatably connected to the filter screen 14. Multiple sets of elastic elements 176 are fixedly installed inside the U-shaped plate 175. One end of each elastic element 176 is fixedly connected to the outer shell 11. The elastic element 176 has a telescopic rod 177 inside, which is fixedly connected to the inner wall of the U-shaped plate 175. After the slurry is screened by the device, impurities with large particle size, high hardness, and high density are separated through the mesh of the filter screen 14 and fall to the upper end of the filter screen 14. At this time, the electric telescopic rod 178 is activated to drive the connecting rod 171 and the extrusion plate 172 and anti-clogging cone 173 at its lower end to move up and down reciprocally. As the anti-clogging cone 173 moves downward, it removes the accumulated material from the discharge plate. Large impurities at the discharge port 111 are cleared to prevent blockage and reduced filtration efficiency of the filter screen 14. Simultaneously, as the extrusion plate 172 and anti-blocking cone 173 move downwards, the extrusion plate 172 draws gas from the U-shaped connecting groove 112. Since the gas volume inside the U-shaped connecting groove 112 is fixed, the gas draw by the extrusion plate 172 causes the connecting rod 174 to move downwards, which in turn causes the U-shaped plate 175 to move downwards. During the up-and-down movement of the extrusion plate 172, the U-shaped plate 175 also moves up and down. Through the elastic element 176 and telescopic rod 177 at the lower end of the U-shaped plate 175, the filter screen 14, which is rotatably connected to the U-shaped plate 175, vibrates as it moves up and down. Because the filter screen 14 is inclined, the vibration causes large impurities at the upper end of the filter screen 14 to roll downwards along its inclined surface, ultimately falling through the discharge port 111 into the waste collection device.

[0032] Working principle: Bentonite slurry enters the outer shell 11 of the tank through the feed inlet 12. After preliminary screening by the filter screen 14, impurities with large particle size, high hardness, and high density cannot pass through the mesh and fall into the discharge outlet 111 into the waste collection device. The filtered slurry enters the arc-shaped bend 16 with protrusions 161 on the inner wall through the collection funnel 15. The protrusions 161 disturb the water flow, causing the denser impurities to settle, while montmorillonite particles enter the sedimentation tank with the water flow for enrichment. When impurities accumulate on the surface of the filter screen 14, the electric motor is activated. The telescopic rod 178 drives the extrusion plate 172 and the anti-clogging cone 173 to move up and down within the square groove 113 and the connecting pipe 114. The anti-clogging cone 173 clears the discharge port 111. At the same time, the extrusion plate 172 draws gas from the U-shaped connecting groove 112. Through air pressure transmission, it drives the connecting rod 174 and the U-shaped plate 175 to move together, causing the filter screen 14 to vibrate under the action of the elastic element 176 and the telescopic rod 177. This causes impurities to roll down the inclined surface to the discharge port 111, achieving continuous and efficient purification and anti-clogging.

[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
