[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art are within the protection scope of this utility model.

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.

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 1-3 As shown, a composite sodium-based bentonite purification and screening device solves the problems of low screening efficiency, poor accuracy, inconvenient component disassembly and assembly, and easy material scattering in existing screening devices. It achieves efficient and accurate multi-stage screening while improving the ease of maintenance and material collection. The device includes a main frame 1, a screening mechanism, and a collection cylinder 9. The screening mechanism is located above the main frame 1, and the collection cylinder 9 is located below the main frame 1. The discharge port of the screening mechanism points towards the inlet of the collection cylinder 9. The main frame 1 is welded from steel, possessing sufficient strength and stability to support the weight of the entire screening mechanism and the collection cylinder 9. The screening mechanism is positioned above the main frame 1, and the collection cylinder 9 is installed below the main frame 1, with the discharge port of the screening mechanism directly facing the inlet of the collection cylinder 9, ensuring that the screened material accurately falls into the collection cylinder 9.

[0020] The screening mechanism includes a conical guide nozzle 6, a screening trough 3, and a vibrator 5. The conical guide nozzle 6 is supported on the upper support plane 2 of the main frame 1 by multiple buffers 7, specifically four to six buffers 7. The conical guide nozzle 6 is made of stainless steel, which has good wear resistance and corrosion resistance. The buffers 7 are evenly distributed around the circumference of the conical guide nozzle 6. This arrangement ensures that the conical guide nozzle 6 is subjected to uniform force during vibration, thus guaranteeing vibration stability. The lower end of the conical guide nozzle 6 is the discharge port, and a through hole corresponding to the discharge port is opened in the middle of the support plane 2 of the main frame 1.

[0021] The screening trough 3 is a cylindrical structure corresponding to the upper end of the conical guide nozzle 6. At least two screening troughs 3 are detachably assembled above the conical guide nozzle 6. In this embodiment, three screening troughs 3 are preferably provided. The screening trough 3 is a cylindrical structure that matches the upper end of the conical guide nozzle 6. It is also made of stainless steel, and a filter plate 4 is fixedly installed inside. The mesh size of the filter plate 4 corresponding to the three screening troughs 3 increases sequentially from top to bottom. For example, the mesh size of the filter plate 4 in the upper screening trough 3 is 100 mesh, the middle layer is 200 mesh, and the lower layer is 300 mesh. This enables three-stage precise screening of the composite sodium-based bentonite raw material, removing impurities of different particle sizes in sequence and improving product purity.

[0022] Vibrators 5 are installed on the outer wall of the conical guide nozzle 6, with multiple vibrators 5 evenly distributed circumferentially around the conical guide nozzle 6. There are 2-4 vibrators 5, uniformly distributed circumferentially around the conical guide nozzle 6. The vibrators 5 are small electric vibrators, and their vibration frequency and amplitude can be adjusted according to actual screening requirements. The vibration energy generated by the vibrators 5 during operation is transmitted to each screening trough 3 through the conical guide nozzle 6, causing the filter plates 4 within the screening trough 3 to vibrate. The material moves continuously on the filter plates 4, accelerating the screening speed and preventing material accumulation and clogging of the screen holes, thus improving screening efficiency.

[0023] In an optional embodiment, the diameter of the perforation is larger than the outer diameter of the corresponding position of the conical guide nozzle 6, providing sufficient circumferential movement space for the vibration of the conical guide nozzle 6 and preventing it from colliding with the support plane 2.

[0024] Furthermore, a columnar structure extends downwards, and a stainless steel sleeve 8 is fitted onto the outside of this columnar structure. The length of the sleeve 8 is determined by the height of the collecting cylinder 9, ensuring that the sleeve 8 can extend into the collecting cylinder 9 and accommodate the longitudinal displacement of the conical guide nozzle 6 during use, avoiding hard contact with the collecting cylinder 9. The collecting cylinder 9 is also made of stainless steel, and its upper end has an assembly hole corresponding to the sleeve 8. The diameter of the assembly hole is larger than the outer diameter of the columnar structure, so as not to affect the circumferential displacement generated by the vibration of the conical guide nozzle 6. A ring of outer flange is welded to the lower edge of the sleeve 8. The diameter of the outer flange is slightly larger than the outer diameter of the sleeve 8. A ring of annular support plate 11 is welded to the inner wall of the collecting cylinder 9. The inner diameter of the ring of support plate 11 is matched with the diameter of the assembly hole, so as to accommodate the circumferential displacement of the conical guide nozzle 6 during vibration. The distance between the ring of support plate 11 and the upper wall of the collecting cylinder 9 is the same as the thickness of the outer flange. When the sleeve 8 is inserted into the collecting cylinder 9, the outer flange can be placed on the ring of support plate 11 to support and fix the sleeve 8, while ensuring the sealing between the sleeve 8 and the collecting cylinder 9, preventing the material from falling out of the gap during the falling process.

[0025] In this embodiment, the cover, the screening troughs 3 and the screening troughs 3, and the conical guide nozzle 6 are connected by ring clamps or quick-release fasteners. The quick-release fasteners are made of common stainless steel quick clamps, which are easy to operate. The screening troughs 3 can be installed and removed simply by turning the handle of the fastener. When it is necessary to replace the filter plates 4 with different mesh sizes, the operation can be completed in a short time, which greatly improves the convenience of maintenance.

[0026] Furthermore, a spiral guide device 10 is connected to the lower end of the collecting cylinder 9. The spiral guide device 10 includes a motor, a reducer, and a spiral conveyor. The motor drives the spiral shaft of the spiral conveyor to rotate through the reducer, conveying the screened material collected in the collecting cylinder 9 from the discharge port to the subsequent processing equipment. The spiral guide device 10 enables continuous material conveying, avoids material accumulation at the bottom of the collecting cylinder 9, and also facilitates subsequent material processing.

[0027] The buffer element 7 is a spring. As a buffer element 7, the spring can effectively absorb vibration energy, reduce the transmission of vibration to the main frame 1, reduce noise during the operation of the device, and at the same time ensure the stability of the screening mechanism during vibration and extend the service life of the device.

[0028] The above are merely preferred embodiments of the present utility model and are 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.
