DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The utility model provides a technical solution: a discharge filtering device of a homogenizer, comprising a shell 1, a filtering chamber 2 and a collecting chamber 3 are provided in the shell 1, the filtering chamber 2 and the collecting chamber 3 are communicated, the slurry processed by the homogenizer is filtered by a filtering mechanism 4 arranged in the filtering chamber 2, and the filtered slurry is centrally collected by a collecting box 5 located in the collecting chamber 3.

[0020] A cover plate 6 is installed on the top of the shell 1. The cover plate 6 is used to close the filter chamber 2 during the filtering process of the slurry by the filtering mechanism 4. The cover plate 6 can prevent external dust from entering the filter chamber 2 during the filtering process of the slurry. The cover plate 6 and the side walls of the collection box 5 are respectively fixedly connected with handle frames, which facilitate the removal of the cover plate 6 and the collection box 5.

[0021] like Figure 2 As shown in the figure, the rear side wall of the housing 1 is equipped with a driving mechanism 7 which is transmission-connected to the filtering mechanism 4. The driving mechanism 7 drives the filtering mechanism 4 to reciprocate in the filtering chamber 2, so that the filtering mechanism 4 can effectively filter the slurry, thereby improving the filtering efficiency of the filtering mechanism 4 on the slurry;

[0022] The filter mechanism 4 includes a mobile frame 41, the middle part of the mobile frame 41 is hollow, and the left and right side walls of the inner cavity of the mobile frame 41 are symmetrically provided with assembly grooves 42, a sliding frame 43 is installed in the assembly groove 42, and a connecting component 8 is installed between the sliding frame 43 and the assembly groove 42. A filter frame 44 is installed in the mobile frame 41, and a filter screen is provided at the bottom of the filter frame 44. The filter frame 44 is detachably fixed to the sliding frame 43 by fixing screws 45. During use, according to the requirements of the number of filter meshes for filtering, the filter frame 44 and the sliding frame 43 can be disassembled, and the filter frame 44 corresponding to the number of filter meshes can be replaced, and the operation process is simpler and more convenient, meeting more requirements for filtering;

[0023] The inner cavity side wall of the filter cavity 2 is integrally formed with a limiting block 10, and a limiting groove 11 is provided on the side wall of the movable frame 41. The limiting block 10 is slidably connected with the limiting groove 11. The moving stroke of the movable frame 41 is limited by setting the limiting block 10 and the limiting groove 11, thereby improving the position stability of the movable frame 41 during the forward and backward movement process in the filter cavity 2;

[0024] like Figure 3 and Figure 4As shown in , the connecting assembly 8 includes a guide shaft 81, which is symmetrically fixed in the assembly groove 42 in the upper and lower directions. The guide shaft 81 passes through the sliding frame 43, and the outer wall of the guide shaft 81 is sleeved with a spring 82, which is located at the front and rear sides of the sliding frame 43. In the process of the driving mechanism 7 driving the mobile frame 41 to move, the action potential energy of the filter frame 44 inside the mobile frame 41 can be increased through the connecting assembly 8. In the process of the mobile frame 41 performing reciprocating motion, the connecting assembly 8 can increase the movement amplitude of the filter frame 44 in the mobile frame 41, thereby further improving the filtering effect of the filter frame 44 on the slurry;

[0025] In order to reduce the impact between the filter frame 44 and the inner wall of the moving frame 41, and prevent the filtered slurry from overflowing from the filter frame 44 due to the impact, rubber pads 46 are fixedly mounted on the front and rear side walls of the inner cavity of the moving frame 41;

[0026] The driving mechanism 7 includes a support frame 71, which is welded and fixed to the rear side wall of the shell 1. A telescopic cylinder 72 is fixedly installed on the top of the support frame 71. The output end of the telescopic cylinder 72 penetrates into the filter chamber 2 and is fixedly connected to the rear side wall of the movable frame 41. The input end of the telescopic cylinder 72 is connected to an external air pump, and the output end of the telescopic cylinder 72 is controlled by the external air pump to move.

[0027] A fixing frame 9 is welded to the side wall of the shell 1. By setting the fixing frame 9, the device can be fixedly assembled with the homogenizer. After the slurry is ground by the homogenizer, the device can be directly used to filter it.

[0028] Working principle: Figure 5 As shown in the figure, the device is fixedly assembled on the side wall of the homogenizer through the fixed frame 9. Before using the homogenizer to process the material, the corresponding filter frame 44 is selected according to the required filtering requirements, the filter frame 44 is connected and fixed to the mobile frame 41, and then the homogenizer is used to process the material. The obtained slurry is directly put into the filter frame 44, and the cover plate 6 is used to close the filter chamber 2 and then the telescopic cylinder 72 of the driving mechanism 7 is opened. The telescopic cylinder 72 drives the mobile frame 41 to reciprocate forward and backward in the filter chamber 2. During the forward and backward movement of the mobile frame 41, the filter frame 44 can be driven by the connecting component 8 to shake forward and backward in the mobile frame 41, and the movement amplitude of the filter frame 44 to move forward and backward is enhanced, thereby improving the filtering effect of the filter frame 44 on the slurry. The qualified slurry after filtering by the filter frame 44 enters the collecting box 5 for collection, and the unqualified slurry remains in the filter frame 44 for subsequent treatment, so as to obtain slurry that meets the standards.
