Description

Technical Field

[0001] The utility model relates to the technical field of industrial salt production, in particular to an impurity removal device for industrial salt production. Background Art

[0002] Industrial salt is one of the most basic raw materials in the chemical industry. Its main components include sodium chloride, sodium nitrite, etc. It is known as the "mother of the chemical industry."

[0003] Before reaching the use standard, industrial salt contains many insoluble impurities, which affect the purification accuracy and need to be removed. According to the authorization document "An impurity removal device for industrial salt production" with publication number CN214389638U3, it is proposed that the current method generally used for industrial salt production impurity removal devices is to dissolve, filter and then remove water. Although it can achieve the effect of removing impurities, the impurity removal efficiency is low and the impurity removal effect is poor due to the relatively simple equipment. It improves the utilization rate of the filtering mechanism by setting the stirring mechanism and the filtering mechanism separately. Since the filter barrel has multiple connection ends, the filtering mechanism can be connected to multiple stirring mechanisms in different working states, shortening the impurity removal cycle. At the same time, a rapid concentrator is added to quickly dehydrate the industrial salt solution after impurity removal, shortening the crystallization time of industrial salt, and further improving the efficiency of industrial salt production impurity removal.

[0004] However, after a long period of filtering, the multiple filter screens inside the filter barrel will inevitably become clogged, thereby affecting the speed and progress of filtering. To this end, we propose an impurity removal device for industrial salt production. Utility Model Content

[0023] See also Figure 2 and Figure 6The positioning mechanism shown in the figure includes two positioning blocks 7 and two positioning grooves 10. The two positioning blocks 7 are symmetrically fixedly connected to the outer arc surface of the annular plate 6. The two positioning grooves 10 are respectively opened on the inner wall of the filter barrel 1 corresponding to the two positioning blocks 7, and the two positioning grooves 10 are respectively slidably matched with the two positioning blocks 7.

[0024] See also Figure 2 , Figure 3 and Figure 6 The fixing mechanism shown in the figure includes a transverse cylinder 8 and a socket 21, the transverse cylinder 8 is fixedly connected to the inner arc surface of the annular plate 6, and the two side walls of the transverse cylinder 8 and the inner wall of the annular plate 6 are slidably inserted with a plug post 16, the outer wall of the plug post 16 is fixedly sleeved with a ring 17, one side wall of the ring 17 is tightly fitted with one side wall inside the transverse cylinder 8, and the ring 17 and the transverse cylinder 8 are slidably matched, and a spring 18 is fixedly connected between the other side wall of the ring 17 and the other side wall inside the transverse cylinder 8, the spring 18 is slidably sleeved on the outer wall of the plug post 16, the socket 21 is opened on the inner wall of the filter barrel 1 corresponding to the plug post 16, and the socket 21 and the plug post 16 are slidably matched, and the end of the plug post 16 away from the socket 21 is fixedly connected with a pull block 9.

[0025] See also Figure 1 and Figure 2 In the figure, the outer wall of the filter barrel 1 is fixedly connected with a plurality of mounting frames 4 in a circular array around its center; specifically, the provision of the plurality of mounting frames 4 facilitates the installation and fixation of the filter barrel 1.

[0026] In this embodiment, first, the solution containing impurities after dissolution is injected into the filter barrel 1 through any one or more injection ports 3 on the barrel cover 2. After the solution containing impurities enters the filter barrel 1, impurities of various sizes can be filtered out from the solution in layers from top to bottom under the filtering action of the conical filter screens 11 on each of the multiple annular plates 6. Impurities of different sizes will be intercepted in each conical filter screen 11 respectively. Since the conical filter screen 11 is conical in shape, the intercepted impurities will gradually accumulate at the bottom of the conical filter screen 11, and will not affect the solution from passing through the middle and upper parts of the conical filter screen 11. The filtered impurity-free solution can flow out through the impurity-free pipeline 5 on the filter barrel 1 and then proceed to the next step of dehydration and other subsequent operations.

[0027] When it is necessary to clean the impurities in the multiple conical filter screens 11 and clean the multiple conical filter screens 11, the multiple conical filter screens 11 can be taken out from the filter barrel 1. The specific operation method is: first, remove the barrel cover 2 from the filter barrel 1, and then pull the two pull blocks 9 with both hands to move the two pull blocks 9 closer to each other. The two pull blocks 9 will respectively drive the respective plug posts 16 to slide closer to each other in the inner wall of the uppermost annular plate 6 and the inner wall of the respective corresponding transverse cylinder 8, and the two plug posts 16 will drive the respective rings 17 to slide closer to each other in the respective corresponding transverse cylinder 8 (in this process, the springs 18 between the two rings 17 and the respective corresponding transverse cylinders 8 will be on the respective corresponding plug posts 16 The two plug posts 16 will slide towards each other in the corresponding sockets 21 on the filter barrel 1 until the two plug posts 16 completely slide out of the corresponding sockets 21. Then, while keeping the two pull blocks 9 pulled, move the two pull blocks 9 upward. Then, the two pull blocks 9 can jointly drive the annular plate 6 located at the top to slide upward in the filter barrel 1 (in this process, the two positioning blocks 7 on the annular plate 6 will slide upward in the positioning grooves 10 on the corresponding filter barrel 1 and completely slide out of the positioning grooves 10). Since a connecting mechanism is provided between two adjacent annular plates 6, multiple annular plates 6 can slide upward in the filter barrel 1 together, and multiple conical filters 11 can be taken out of the filter barrel 1. Similarly, the multiple conical filters 11 after cleaning can be installed back into the filter barrel 1 according to the opposite operation, which is easy to operate.

[0028] Embodiment 2

[0029] See also Figure 3-Figure 5 The present embodiment further explains the first embodiment. The guide mechanism in the figure includes a T-shaped slot 19 and a T-shaped block 20. The T-shaped block 20 is fixedly connected to the upper edge of the side wall of the connecting plate 12 corresponding to the second connecting plate 14. The T-shaped slot 19 is opened at the side wall of the connecting plate 12 corresponding to the T-shaped block 20, and the T-shaped slot 19 and the T-shaped block 20 are slidably matched.

[0030] See also Figure 2 and Figure 5 As shown in the figure, the locking mechanism includes two screws 13 and two groups of screw holes 15. The two groups of screw holes 15 are symmetrically arranged on the side wall of the connecting plate 12 corresponding to the connecting plate 14 in the front and back directions. The two screws 13 are symmetrically penetrated and tightened at the lower edge of the side wall of the connecting plate 12 in the front and back directions, and the two screws 13 are respectively inserted into and tightened in the topmost screw hole 15 in the two groups of screw holes 15.

[0031] Working principle: When it is necessary to shorten the distance between two adjacent conical filters 11 to accommodate the installation of multiple conical filters 11 in a filter barrel 1 with a lower height, it can be achieved by shortening the distance between two adjacent annular plates 6. Taking the annular plate 6 located at the top and the annular plate 6 adjacent to the annular plate 6 as examples, first, turn outward in sequence the two screws 13 on one of the connecting plates 12 located on the top annular plate 6. Both screws 13 will turn outward on the inner wall of the connecting plate 12, and the two screws 13 will also turn outward in the screw holes 15 on one of the connecting plates 14 on the other corresponding annular plate 6, until the two screws 13 are completely turned away from their corresponding screw holes 15. Similarly, follow the same operation. The two screws 13 on the other connecting plate 1 12 on the topmost annular plate 6 can be completely turned away from the screw holes 15 on the other connecting plate 2 14 on the other corresponding annular plate 6, and then the distance between the two connecting plates 1 12 and the corresponding connecting plates 2 14 can be adjusted as needed (in this process, the T-shaped blocks 20 on the two connecting plates 2 14 will slide in the T-shaped grooves 19 on the corresponding connecting plates 1 12), and then the four screws 13 are tightened in the inner walls of the two connecting plates 1 12 and the other screw holes 15 on the corresponding connecting plates 2 14, and then the two connecting plates 1 12 and the corresponding connecting plates 2 14 can be fixed again, and the distance between the two adjacent conical filter screens 11 can be shortened. Similarly, the distance between the other two adjacent conical filter screens 11 can be shortened according to the same operation, and multiple conical filter screens 11 can be installed in a filter barrel 1 with a lower height, which has good applicability.
