[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Embodiment 1:

[0029] Reference Figure 1-4 A filter for filtering mechanical impurities, comprising a shell 101 and a shell 2 102, wherein the shell 101 and the shell 2 102 are installed by bolts, and further comprising: a bottom plate 103, fixedly connected to the shell 101; a mounting groove 104, arranged on the bottom plate 103, and a support tube 201 is rotatably connected to the mounting groove 104; a plurality of groups of empty holes, all arranged on the support tube 201; a plurality of groups of mounting holes 105, all arranged on the bottom plate 103, and mounting bolts 4 are threadedly connected to the mounting holes 105; a filter cloth, arranged in the support tube 201, the filter cloth matches the inner wall of the support tube 201, and the filter cloth is connected to the support tube 201 by mounting bolts 4; a drain pipe 1011 is connected to the shell 1, and a valve is arranged in the drain pipe 1011.

[0030] When the device is in use, the shell 101 and the shell 2 102 are respectively installed on the pipeline for liquid circulation, and then the support tube 201 is installed on the bottom plate 103, and the filter cloth is placed in the support tube 201, and the corners of the filter cloth are taken out, placed on the bottom plate 103, and installed and fixed by installing bolts 4, and a sealing gasket can be appropriately added to improve the sealing effect. Then, the shell 101 and the shell 2 102 are installed together by bolts. At this time, the evenly distributed holes on the support tube 201 are used for material circulation, which supports the filter cloth without affecting the material flow rate, and removes mechanical impurities in the raw materials, intermediate products and products flowing through the filter, which can effectively improve the quality of the raw materials, intermediate products and products.

[0031] When the filter cloth needs to be replaced later, stop the flow of liquid in the liquid circulation pipeline, open the valve set in the drain pipe 1011, drain the excess liquid in the shell, and then open the shell to replace the filter cloth.

[0032] Embodiment 2:

[0033] Reference Figure 1-5, a filter for filtering mechanical impurities, which is basically the same as Example 1, and further: a mounting column 204 is fixedly connected inside a support tube 201, a mounting tube 301 is plugged onto the mounting column 204, one end of the mounting tube 301 is located inside a second shell 102, a paddle 302 is fixedly connected to one end of the mounting tube 301 located at the second shell 102, a puncture head is provided at one end of the mounting tube 301 away from the paddle 302, a clamping ring 202 is provided on the support tube 201, the support tube 201 is rotatably connected to the mounting groove 104 through the clamping ring 202, the support tube 201 can cover the mounting groove 104 to prevent a large amount of impurities from entering, a plurality of groups of rotating beads 203 are rotatably connected to the clamping ring 202, and the rotating end of the rotating bead 203 is in contact with the mounting groove 104.

[0034] When the device is in use, after the filter cloth is installed, the puncture head can be used to pierce the filter cloth. Due to the setting of the mounting post 204, the filter cloth can be moved to the bottom of the support tube 201 by pressing it around the mounting post 204. As shown in the figure, since the mounting tube 301 is smaller than the mounting post 204, the filter cloth will be stretched open by the support tube 201 at this time, which can effectively prevent the leakage of impurities. Then the upper shell 102 can be installed. At this time, through the setting of the mounting tube 301, when the liquid flows, it will drive the rotation of the paddle 302, and since the mounting tube 301 is plugged into the mounting post 204, the support tube 201 will also rotate at this time. The rotation speed is related to the flow rate of the liquid. The rotation at this time will cause the position of the empty hole to change continuously, thereby avoiding a large amount of impurities from accumulating in the empty hole and affecting the filtering effect.

[0035] The utility model uses evenly distributed holes on the support tube 201 for material circulation, which supports the filter cloth without affecting the material flow rate, and filters out mechanical impurities in the raw materials, intermediate products and products flowing through the filter, which can effectively improve the quality of the raw materials, intermediate products and products.

[0036] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
