Description

Technical Field

[0001] This utility model relates to the field of sodium hydrosulfide concentrators, specifically a filter element structure for a sodium hydrosulfide concentrator. Background Technology

[0002] Sodium hydrosulfide (NaHS) is an important inorganic compound, usually a white or pale yellow crystalline powder, readily soluble in water and alcohol, with an alkaline aqueous solution. In the dye industry, it is used as a synthetic organic intermediate and an auxiliary agent for sulfur dyes. In the leather industry, it is used for dehairing raw hides and tanning, improving leather quality. In the fertilizer industry, it can remove monomeric sulfur from activated carbon desulfurizers, improving fertilizer purity, etc. It is widely used in various industries. During production, a concentrator is needed to increase its concentration and filter impurities generated during production.

[0003] Existing sodium hydrosulfide concentrator filter elements are used through an inner cylinder, filter screen, guide rod, etc. After the sodium hydrosulfide solution enters the concentrator, it first enters the space between the inner cylinder and the filter screen through the holes on the side wall of the inner cylinder. Under the action of pressure difference, the clear liquid passes through the filter screen and enters the inner cylinder, while solid particles are intercepted on the outside of the filter screen. During use, large particles are easy to remain in the holes of the inner cylinder, affecting the filtration efficiency of sodium hydrosulfide.

[0004] Therefore, this utility model proposes a sodium hydrosulfide concentrater filter element structure to solve the above-mentioned problems. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a sodium hydrosulfide concentrater filter element structure, the sodium hydrosulfide concentrater filter element structure includes: a side plate 1, an inner cylinder 2 fixedly installed on the side wall of the side plate 1, a plurality of guide rods 3 evenly distributed in a ring array fixedly installed on the side wall of the side plate 1, a filter screen 4 sleeved on the outer surface of the guide rods 3, a cover plate 5 installed on the side wall of the guide rods 3, a rotating mechanism 6 installed on the side wall of the side plate 1 and the cover plate 5, an efficiency enhancement component 7 installed inside the rotating mechanism 6, the rotating mechanism 6 includes a bearing 8, the bearing 8 is embedded in the center of the inner wall of the side plate 1 and the cover plate 5, and a rotating ring 9 is installed inside the bearing 8;

[0022] In use, the inner cylinder 2 is installed inside the side plate 1, and the filter screen 4 is supported and fixed by the guide rod 3 to prevent the filter screen 4 from deforming. At the same time, the filter screen 4 and the inner cylinder 2 filter out large particles and impurities in the sodium hydrosulfide, preventing impurities and large particles from entering the thickener. When the thickener is in use, the flowing sodium hydrosulfide liquid is drawn into the filter element by the suction of the thickener and flows out through the center outlet of the side plate 1 or the cover plate 5. When the sodium hydrosulfide liquid flows, the rotating ring 9 is rotated by the bearing 8 in the rotating mechanism 6, so that the efficiency enhancement component 7 can rotate with the flow of liquid, thereby increasing the flow rate of sodium hydrosulfide and improving the transport rate. At the same time, it can also prevent particles from clogging the holes of the inner cylinder 2 and affecting the flow of liquid.

[0023] Example 2: Based on Example 1, a structure is provided to accelerate the flow rate and flowability of sodium hydrosulfide. The enhancement component 7 includes a set of connecting rods 10. The two ends of the connecting rods 10 are fixed to the side wall of the rotating ring 9. The set of connecting rods 10 are evenly distributed in a ring array on the side wall of the rotating ring 9. A rotating plate 11 is installed on the outer surface of the connecting rods 10. The outer side wall of the rotating plate 11 is in contact with the inner wall of the inner cylinder 2. Several wide-mouth through grooves 12 are opened on the surface of the rotating plate 11. The wide-mouth through grooves 12 are evenly distributed in an array on the surface of the rotating plate 11. Limiting rings 13 are installed on the outer surface of the rotating ring 9. The limiting rings 13 facilitate the limiting and fixing of the sealing ring 14 and the bearing 8. The sealing ring 14 is installed on the side wall of the limiting ring 13. The sealing ring 14 can prevent the bearing 8 from contacting sodium hydrosulfide, thereby affecting the rotation performance of the bearing 8. The sealing ring 14 is in contact with the outer side wall of the bearing 8, the side plate 1, and the side wall of the cover plate 5.

[0024] In use, the enhancement component 7 fixes the rotating plate 11 between the rotating rings 9 via the connecting rod 10. When sodium hydrosulfide is drawn into the filter element by the traction force, the flow rate of the sodium hydrosulfide liquid will push the surface of the rotating plate 11 to rotate the rotating plate 11. At the same time as the rotating plate 11 rotates, the flow rate of the liquid will increase. The wide through groove 12 between the rotating plates 11 facilitates the flow of sodium hydrosulfide liquid and avoids the rotating plate 11 from having too large a contact area with the liquid, which would increase the force area of ​​the rotating plate 11 and thus increase the rotation speed, which would easily cause mechanical damage. When the rotating plate 11 rotates, the side wall of the rotating plate 11 is in contact with the inner wall of the inner cylinder 2, which can prevent particulate matter from clogging the holes of the inner cylinder 2.

[0025] Example 3: Based on Example 2, a design is provided to facilitate the fixed installation of the filter element. The side wall of the guide rod 3 is provided with a threaded groove 15. The side wall of the cover plate 5 is provided with a number of annularly arranged and evenly distributed screws 16. The screws 16 penetrate the side wall of the cover plate 5 and enter the interior of the threaded groove 15. The side walls of both the side plate 1 and the cover plate 5 are provided with threaded interfaces 17.

[0026] In use, the cover plate 5 is fixed to the guide rod 3 by screws 16, so that the cover plate 5 can fix the rotating mechanism 6 and the efficiency enhancement component 7. The filter element can be easily installed inside the thickener through the threaded interface 17.

[0027] In actual use, the cover plate 5 is fixed to the guide rod 3 by screws 16, so that the cover plate 5 can fix the rotating mechanism 6 and the efficiency enhancement component 7. The threaded interface 17 facilitates the installation of the filter element inside the thickener. When the thickener is in use, the flowing sodium hydrosulfide liquid is drawn into the filter element under the suction of the thickener. The rotating ring 9 is rotated by the bearing 8 in the rotating mechanism 6, which in turn causes the efficiency enhancement component 7 to fix the rotating plate 11 between the rotating rings 9 through the connecting rod 10. The sodium hydrosulfide is drawn into the filter element under the traction force. When the sodium hydrosulfide liquid flows, it pushes the surface of the rotating plate 11 to rotate. As the rotating plate 11 rotates, the flow rate of the liquid increases. The wide-mouthed through groove 12 between the rotating plates 11 facilitates the flow of sodium hydrosulfide liquid while preventing the rotating plate 11 from having an excessively large contact area with the liquid, which would increase the force area of ​​the rotating plate 11 and thus increase the rotation speed, thereby easily causing mechanical damage. When the rotating plate 11 rotates, the side wall of the rotating plate 11 is in contact with the inner wall of the inner cylinder 2, which can prevent particulate matter from clogging the holes of the inner cylinder 2.

[0028] 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.
