[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 5 As shown, an industrial filter that is easy to clean internally includes a filter housing 1 and a filter tank 12. A liquid inlet pipe 6 is connected to the top of the filter housing 1. A lifting mechanism 5 is provided on the outside of the liquid inlet pipe 6. The lifting mechanism 5 flushes the internal filter device of the filter housing 1 and the interior of the filter housing 1 according to the needs of use. A guide mechanism 10 is provided inside the filter housing 1. The guide mechanism 10 positions the filter device and vertically guides the vertically pulled components when the equipment is replaced.

[0024] In this embodiment, the lifting mechanism 5 includes a base 2, an electric cylinder 3, a cover plate 4 and a side support frame 7. The base 2 is distributed in a ring shape on the outside of the filter housing 1. The outside of one group of the bases 2 is connected to the electric cylinder 3, and the output end of the electric cylinder 3 is connected to the side support frame 7. The outside of the side support frame 7 is penetrated by a liquid inlet pipe 6, and the bottom end of the liquid inlet pipe 6 is penetrated by the cover plate 4. The cover plate 4 and the filter element are driven by the electric cylinder 3 to be vertically separated, thereby improving the efficiency of equipment disassembly and maintenance.

[0025] In this embodiment, the cover plate 4 is connected to the top of the filter tank 12 through a liquid inlet pipe 6 that penetrates and connects the cover plate 4 . The sewage is directly injected into the filter tank 12 through the liquid inlet pipe 6 , and the filter tank 12 is used to roughly filter the sewage.

[0026] In this embodiment, the guide mechanism 10 includes a damping rubber pad 8, a vertical guide rod 9, an inner guide tube 11, an inner threaded joint 13 and a filter bag 14. The damping rubber pad 8 is arranged at the bottom end of the vertical guide rod 9, and the damping rubber pad 8 is arranged inside the inner guide tube 11. The inner guide tube 11 is distributed in a ring shape inside the filter housing 1. The inside of the filter housing 1 is provided with multiple groups of filter bags 14 of the same size. The top of the filter bag 14 is connected with an inner threaded joint 13. By setting multiple groups of inner threaded joints 13 to connect the top of the filter bag 14, the efficiency of sewage separation, purification and filtration is improved.

[0027] In this embodiment, the filter tank 12 is connected to the inner guide tube 11 via a vertical guide rod 9 penetrating from the outside, and the interior of the inner guide tube 11 is vertically guided and limited by the vertical guide rod 9 .

[0028] In this embodiment, a liquid discharge pipe 15 is connected through the bottom end of the filter housing 1 , and the filtered liquid is directly discharged through the liquid discharge pipe 15 .

[0029] In this embodiment, the filter tank 12 is connected to the top of the filter bag 14 through an internal thread joint 13 provided in an annular manner at the bottom end, and is connected to the top of the filter bag 14 by providing multiple groups of internal thread joints 13 .

[0030] The practical application of this industrial filter that is easy to clean internally includes the following work:

[0031] Step 1: The operator connects the bottom end of the cover plate 4 to the top end of the filter tank 12, fills the filter tank 12 with filter material, connects the internal thread joint 13 to the top end of the filter bag 14, and injects liquid into the liquid inlet pipe 6, directly injects sewage into the filter tank 12, and after the liquid is roughly filtered by the filter filler inside the filter tank 12, the liquid is injected into the filter bag 14 through the bottom internal thread joint 13;

[0032] Step 2: After the liquid is filtered again by multiple groups of filter bags 14 with the same diameter, the purified liquid is directly discharged through the drainage pipe 15 arranged at the bottom. When the filter housing 1 needs to be disassembled and rinsed, the electric cylinder 3 is opened to drive the side support frame 7 and the cover plate 4 to be vertically lifted, so that the filter tank 12 and the filter bag 14 are taken out from the inside of the filter housing 1;

[0033] Step 3: The operator separates the filter bag 14 from the internal joint 13, performs high-pressure flushing on the inside of the filter housing 1 with a high-pressure water gun to flush out the dirt inside the filter housing 1, and then discharges the sewage through the drainage pipe 15. When the side support frame 7 rises vertically, the vertical guide rod 9 penetrating the outside of the filter tank 12 is used to vertically guide the inside of the inner guide tube 11;

[0034] Step 4: When the damping rubber pad 8 at the bottom end of the vertical guide rod 9 moves vertically in the inner guide tube 11, the damping rubber pad 8 increases the friction force of the vertical guide rod 9 during the upward movement, thereby vertically guiding the filter tank 12 and the filter bag 14 to prevent the filter tank 12 from being displaced or tilted during the vertical ascent of the filter tank 12 and the filter bag 14.

[0035] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
