Description

Technical Field

[0001] This utility model relates to the field of bentonite technology, specifically to a bentonite impurity removal device. Background Technology

[0002] Bentonite is a clay mineral with adsorption and expansion properties, and it is widely used in many fields, including building materials, ceramics, cosmetics, medicine, and environmental protection. The main applications of bentonite in various fields include the following: Bentonite can be used to manufacture building materials such as bricks, tiles, cement, and concrete, and it can improve the plasticity, fluidity, and durability of the materials.

[0003] In existing technologies for screening bentonite, after the bentonite is processed into powder, many large granular impurities are mixed in. The hardness of these impurities is generally greater than that of bentonite. Therefore, these large particles can only be mixed in with the bentonite. Since most filter screens are horizontally set, material or impurities easily accumulate on top of the screen, causing blockage. During screening, workers usually have to pick out large particles such as quartz, mica, and feldspar from the bentonite powder, which is a waste of manpower and resources. To address this, we propose a bentonite impurity removal device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bentonite impurity removal device. This device solves the technical problem that most filters are horizontally set up, and the screen itself is prone to clogging due to the accumulation of materials or impurities. In most screening processes, workers are required to pick out large particles of impurities from the bentonite powder, which is a waste of manpower and resources.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bentonite impurity removal device includes a cylindrical primary screening box. The primary screening box has an inlet at its top and an outlet on its side wall near the bottom. Two L-shaped, opposing slide rails are installed inside the primary screening box. A large-diameter screen is slidably mounted on the two slide rails. Each end of the large-diameter screen has a notch that slides on the slide rail. Two opposing pull rings are provided on the top surface of the large-diameter screen for easy lifting. A small-diameter screen is fixedly mounted on the side wall of the primary screening box. The small-diameter screen is located below the large-diameter screen. The bottom of the primary screening box is equipped with a first motor. A first rotating shaft with a vertical orientation is fixedly installed on the output end of the first motor. A first lever is fixedly installed on the first rotating shaft. The first lever is located between the large-diameter screen and the small-diameter screen and is in close contact with the upper surface of the small-diameter screen. A detachable second lever is also fixedly installed on the first rotating shaft. The second lever is close to the upper surface of the large-diameter screen. The side near the discharge port is connected to the secondary screening box.

[0007] Working principle:

[0008] When bentonite is needed to remove impurities, the operator first pours the bentonite into the feed inlet. Then, the bentonite that has not been impurity removed is poured into the large-diameter screen in the primary screening box. Next, the operator starts the first rotating shaft, which drives the second lever to rotate. The second lever disperses the bentonite on the large-diameter screen and separates the impurities within the bentonite. At this time, the bentonite filtered once falls from the large-diameter screen onto the upper surface of the small-diameter screen. Then, the first rotating shaft drives the first lever to rotate, which rotates the bentonite on the small-diameter screen and filters it to the bottom of the primary screening box. Finally, the bentonite filtered twice is moved to the secondary screening box and collected.

[0009] The beneficial effects of this utility model are as follows:

[0010] The bentonite is filtered twice using both large-diameter and small-diameter screens, removing impurities. A sliding rail system allows the large-diameter screen to slide out of the primary screening box, enabling operators to quickly remove impurities from it. Then, the first motor is activated, driving a rotating shaft that in turn moves a first and a second lever to separate the bentonite from the large-diameter and small-diameter screens, further differentiating impurities. The screened bentonite is then collected through a discharge port. Attached Figure Description

[0013] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 As shown, a bentonite impurity removal device includes a cylindrical primary screening box 1. The top of the primary screening box 1 has an inlet 2, and the side wall near the bottom of the primary screening box 1 has an outlet 3. Two L-shaped, opposing slide rails 4 are provided inside the wall of the primary screening box 1. A large-diameter screen 5 is slidably mounted on the two slide rails 4. Each end of the large-diameter screen 5 has a notch 26 that can slide on the slide rail 4. Two opposing pull rings 27 are provided on the top surface of the large-diameter screen 5 to facilitate lifting. A small-diameter screen 6 is fixedly mounted on the side wall of the primary screening box 1. The small-diameter screen 6 is located below the large-diameter screen 5. The bottom of the primary screening box 1 is equipped with a first motor 7. A first rotating shaft 8 is fixedly installed on the output end of the first motor 7, and a first lever 9 is fixedly installed on the first rotating shaft 8. The first lever 9 is located between the large-diameter screen 5 and the small-diameter screen 6, and the first lever 9 is in close contact with the upper surface of the small-diameter screen 6. A detachable second lever 10 is also fixedly installed on the first rotating shaft 8. The second lever 10 is close to the upper surface of the large-diameter screen 5, and a secondary screening box 11 is conductively connected to the side near the discharge port 3.

[0015] When bentonite is needed to remove impurities, the operator first pours the bentonite into the feed inlet 2. Then, the bentonite that has not been impurity removed is poured onto the large-diameter screen 5 in the primary screening box 1. Next, the operator starts the first rotating shaft 8, which drives the second lever 10 to rotate. The second lever 10 disperses the bentonite on the large-diameter screen 5 and separates the impurities in the bentonite. At this time, the bentonite filtered once falls from the large-diameter screen 5 onto the upper surface of the small-diameter screen 6. Then, the first rotating shaft 8 drives the first lever 9 to rotate. The first lever 9 rotates the bentonite on the small-diameter screen 6 and filters the bentonite on the small-diameter screen 6 to the bottom of the primary screening box 1. Finally, the bentonite filtered twice is moved to the secondary screening box 11 and collected.

[0016] The bentonite is filtered twice by the large-diameter screen 5 and the small-diameter screen 6, which removes impurities from the bentonite. The large-diameter screen 5 can be slid out of the primary screening box 1 by the slide rail 4, allowing the operator to quickly remove the impurities on the large-diameter screen 5. Then, by starting the first motor 7, the first motor 7 drives the first rotating shaft 8 to rotate. The first rotating shaft 8 drives the first lever 9 and the second lever 10 to separate the bentonite on the large-diameter screen 5 and the small-diameter screen 6, so as to distinguish the impurities in the bentonite. The screened bentonite can be collected through the discharge port 3.

[0017] like Figure 1 As shown, the secondary screening box 11 has a through hole 12 on one side; it also includes a handle 15, a sleeve 16, and a magnet 17. The sleeve 16 is slidably installed in the through hole 12, the magnet 17 is installed in the sleeve 16, and the handle 15 is horizontally fixed on the sleeve 16 and faces the outside of the secondary screening box 11. It also includes a fan 18, a duct 19, and a guide plate 20. The fan 18 is fixedly installed on one side of the primary screening box 1, one end of the duct 19 is fixedly installed at the outlet of the fan 18, and the other end of the duct 19 passes through the primary screening box 1 and is opposite to the secondary screening box 11 installed on the primary screening box 1. The air guide plate 20 is fixedly sleeved on the air duct 19 and faces the through hole 12. It also includes a sleeve rod 13 and a bolt 14. The sleeve rod 13 is sleeved on the top of the first rotating shaft 8. The bolt 14 passes through the sleeve rod 13 and is screwed to the first rotating shaft 8. The second lever 10 is fixedly installed on one side of the sleeve rod 13. The top of the feed inlet 2 is provided with an air hood 21. A dust suction pipe 22 is conductively connected to the air hood 21. The dust suction pipe 22 is connected to a vacuum cleaner 23. A feeding conveyor 24 is provided between the air hood 21 and the feed inlet 2. It also includes a collection box 25 with an opening at the top. The collection box 25 is located at the bottom of the secondary screening box 11 and is used to collect materials.

[0018] The through-hole 12 facilitates the transfer of bentonite filtered in the primary screening box 1 to the secondary screening box 11. The magnet 17 can adsorb some magnetic metal impurities in the bentonite. The handle 15 and sleeve 16 can remove the metal impurities adsorbed on the sleeve 16. The blower 18 can blow the bentonite filtered twice into the secondary screening box 11. The dust collector 23 and fan hood 21 can adsorb the dust generated in the filtered bentonite, thereby reducing the harm of dust to the operators. The feed conveyor 24 can facilitate the entry of bentonite into the primary screening box 1. The collection box 25 can collect the filtered bentonite. The pull ring 27 can quickly pick up the large-diameter screen 5.
