They are used only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected" and "linked" used in this utility model should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0019] like Figure 1 , 2 The bentonite dry purification equipment shown can achieve uniform feeding of bentonite, effectively improve the separation effect of impurities and purified bentonite, improve purification efficiency and product quality, and has the characteristics of simple structure, stable operation and convenient maintenance. It is suitable for industrial continuous production. Specifically, it includes a purification chamber 1, a filter cylinder 9, a feed cylinder 4 and a slag discharge chamber 3. The purification chamber 1 is set on the main frame, which is welded from square steel or I-beams. The bottom can be fixed to the concrete ground by pre-embedded bolts. The lower end of the purification chamber 1 is provided with a discharge port 8, which opens downward. A conveyor belt or a receiving trough can be set below the discharge port 8.

[0020] The filter cylinder 9 is placed inside the purification chamber 1. The side wall of the filter cylinder 9 has an array of filter holes, the diameter of which can be set to 0.1-0.5 mm according to actual purification requirements. A horizontally extending main shaft 11 is rotatably mounted inside the purification chamber 1. The main shaft 11 is concentrically mounted with the filter cylinder 9. One end of the main shaft 11 extends out of the purification chamber 1 and is connected to a power unit 5. Driven by the power unit 5, the main shaft 11 and the filter cylinder 9 can be driven. The feed cylinder 4 is located at the end of the purification chamber 1 corresponding to the power unit 5 and is concentrically mounted with the main shaft 11. The feed cylinder 4 is fixedly connected to the purification chamber 1. The end of the feed cylinder 4 corresponding to the power unit 5 is a closed end. The main shaft 11 passes through this closed end and is connected to the power unit 5. The other end of the feed cylinder 4 passes through the purification chamber 1 and extends into the filter cylinder 9. The outer wall of the main shaft 11 is provided with a spiral feed plate 12 corresponding to the feed cylinder 4. The spiral feed plate 12 is welded and fixed, and the pitch of the spiral feed plate 12 is 50-100mm. A feed inlet is provided above the feed cylinder 4, and a hopper 7 is provided on the feed inlet. The upper opening of the hopper 7 is funnel-shaped to facilitate feeding, so that the material to be purified can be introduced into the hopper 7. When the main shaft 11 rotates, the spiral feed plate 12 can evenly and stably transport the bentonite raw material in the feed cylinder 4 to the filter cylinder 9, avoiding the problem of local accumulation of bentonite in the filter cylinder 9, ensuring the stable progress of the purification process, and helping to improve the purification effect and product quality consistency. The side wall of the filter cylinder 9 is provided with an array of filter holes, which can effectively separate impurities in the bentonite. Bentonite particles that meet the requirements enter the purification chamber 1 through the filter holes, while impurities are trapped in the filter cylinder 9.

[0021] In an optional embodiment, the slag discharge chamber 3 is located at the end of the purification chamber 1 away from the feed cylinder 4. A slag discharge port is provided below the slag discharge chamber 3. The slag discharge chamber 3 is fixedly connected to the purification chamber 1. The end of the filter cylinder 9 extends into the slag discharge chamber 3. Impurities in the bentonite raw material (such as quartz, feldspar, etc.) cannot pass through the filter pores due to their large particle size and are trapped in the filter cylinder 9. As the filter cylinder 9 continues to rotate, the impurities gradually move towards the open end of the filter cylinder 9 under the combined action of centrifugal force and gravity, and finally enter the slag discharge chamber 3. Then, they are discharged from the slag discharge port below the slag discharge chamber 3, thus achieving the separation of impurities. The filter cylinder 9 has an open end that extends into the slag discharge chamber 3. An inwardly extending baffle ring is provided along the inner edge of its side wall. The height of the baffle ring is 5-10mm. By blocking the baffle ring, the screening time of the material in the filter cylinder 9 is guaranteed, the screening effect is improved, and the impurities are ensured to be fully screened before entering the slag discharge chamber 3 and being discharged. This improves the thoroughness of the separation between the impurities and the purified bentonite, thereby improving the purification efficiency.

[0022] Furthermore, the filter cylinder 9 and the main shaft 11 are supported by multiple sets of support mechanisms, which ensures the coaxiality of the filter cylinder 9 and the main shaft 11 and prevents the filter cylinder 9 from shifting during rotation. The rubber columns in the support mechanism can play a role in buffering and shock absorption, reducing wear between components, extending the service life of the equipment, and improving the stability of equipment operation.

[0023] The support mechanism includes multiple spokes 10 evenly distributed around the main shaft 11. The spokes 10 are steel bars. The main shaft 11 is provided with inner hoops corresponding to the spokes 10. The inner wall of the filter cylinder 9 is provided with sleeves corresponding to the spokes 10. The inner hoops and sleeves are used to fix the two ends of the spokes 10, ensuring the installation of the spokes 10 firmly. A rubber post is threaded into the sleeve. The end of the rubber post is provided with a corresponding insertion hole for the spoke 10. The end of the spoke 10 is inserted into the insertion hole of the rubber post. The insertion hole is a blind hole. Because the rubber post has a certain elasticity, it can buffer and dampen the filter cylinder 9 during equipment operation, reduce wear between the spokes 10 and the sleeve, extend the service life of the equipment, and also facilitate the installation and disassembly of the spokes 10, reducing maintenance costs.

[0024] A cover plate 2 is bolted to the top of the purification chamber 1. A sealing gasket is provided between the cover plate 2 and the purification chamber 1 to prevent dust from escaping. The cover plate 2 can also be removed for internal maintenance. A conical guide is installed at the lower end of the purification chamber 1, and a discharge port 8 is provided at the lower end of the conical guide. The power unit 5 is a drive motor, which is connected to the main shaft 11 via a belt drive mechanism 6. The drive motor is bolted to the main frame, and its output shaft is connected to the main shaft 11 via the belt drive mechanism 6. The belt drive mechanism 6 includes a driving pulley, a driven pulley, and a transmission belt. The driving pulley is mounted on the output shaft of the drive motor, and the driven pulley is mounted on the end of the main shaft 11 extending out of the purification chamber 1. The transmission belt is fitted onto the driving pulley and the driven pulley. During equipment operation, the rotation speed of the main shaft 11 and the filter cartridge 9 can be controlled by adjusting the speed of the drive motor according to actual purification needs, thereby controlling the feeding speed and centrifugal separation effect to achieve the best purification effect. Meanwhile, the cover plate 2 above the purification chamber 1 should be opened regularly to clean and maintain the interior of the purification chamber 1 and the filter cartridge 9, ensuring the normal operation of the equipment.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
