Specific Embodiment
[0020] The following further describes in detail the embodiments of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] In the embodiment of the present disclosure, the filter mesh shell 9 is a through cylindrical structure on the left and right. Five hundred and eighty-seven groups of through holes with a diameter of 12 mm are arranged around the inner side surface of the filter mesh shell 9. This not only enables the sludge flow area to be satisfied, reduces the resistance of sludge transportation, but also filters the wet sludge through the through holes of the filter mesh shell 9, so that plastic fillers, stones and iron hard objects are retained inside the cylinder of the filter mesh shell 9. A threaded structure is provided at the position near the right end of the inner side surface of the cylinder structure of the filter mesh shell 9. Three sets of ring plates are provided on the outer side surface of the filter mesh shell 9, and the three sets of ring plates limit and reinforce the filter mesh shell 9, improving the stability of the cylinder structure of the filter mesh shell 9 and preventing the filter mesh shell 9 from deforming structurally due to the impact and extrusion of impurities inside the sludge during the sludge flow process.
[0023] In the embodiment of the present disclosure, six through holes are provided on the left side surface of the retaining disc 2. The through holes of the retaining disc 2 are arranged in a circular array around the horizontal central axis of the retaining disc 2. Each through hole is inserted with a clamping bolt 10. A cylindrical convex column is provided at the center position of the left side surface of the retaining disc 2, and a thread is provided on the outer side surface of the convex column. The threaded structure on the inner side surface of the cylinder structure of the filter mesh shell 9 is screwed to the threaded structure on the outer side surface of the convex column of the retaining disc 2. Manually rotate the filter mesh shell 9, and the filter mesh shell 9 is separated and removed from the retaining disc 2, which is convenient for the separate removal and cleaning of the filter mesh shell 9.
[0024] In the embodiment of the present disclosure, the filter housing 1 is a T-shaped tee pipe body structure. The right ends of the filter housing 1 are both flange-like structures. Six groups of through holes are provided on the flange of the right end of the filter housing 1. The through holes are distributed in a circular array around the horizontal central axis of the flange of the filter housing 1. The through holes of the flange at the left end of the filter housing 1 are opposite to the through holes of the retaining disc 2 in the front and back directions. The clamping bolts 10 are inserted into the through holes of the flange at the right end of the filter housing 1. The clamping bolts 10 cooperate with the clamping nuts 11 meshed with the external thread on the side surface to complete the installation and disassembly of the retaining disc 2 at the right end of the filter housing 1, so that the retaining disc 2 can drive the filter mesh housing 9 to be separated and removed from the inside of the filter housing 1 for regular removal of sludge impurities.
[0025] In the embodiment of the present disclosure, the hanging bracket 14 is a circular frame structure. The outer side surface of the hanging bracket 14 is closely attached to the inner side surface of the filter mesh housing 9. During the process of the separation and movement of the filter mesh housing 9 and the retaining disc 2, the outer side surface of the hanging bracket 14 scrapes the inner side surface of the cylinder of the filter mesh housing 9, so that the hanging bracket 14 scrapes and removes the solid impurities adhering to the inner side surface of the filter mesh housing 9, reducing the cleaning difficulty of the inner side surface of the filter mesh housing 9 and facilitating the subsequent separate flushing and cleaning of the filter mesh housing 9.
[0026] In the embodiment of the present disclosure, the lower side surface of the flow rate pipe 4 is bolted to the filter housing 1, and the top end of the flow rate pipe 4 is bolted to the pressure measuring pipe 6. The electromagnetic flowmeter 7 and the pressure gauge 5 installed on the flow rate pipe 4 and the pressure measuring pipe 6 respectively are used to detect the sludge flow rate and pressure at the water outlet end at the top of the T-shaped filter housing 1, so as to determine whether the filter mesh housing 9 is blocked, facilitating the timely cleaning of the filter mesh housing 9.
[0027] The specific usage mode and function of this embodiment:
[0028] When the utility model filters impurities in the sludge conveying pipeline, wet sludge containing impurities flows into the filter mesh shell 9 inside the filter pipe shell 1 through the water inlet pipe 8. Then, the wet sludge flows through the five hundred and eighty-seven groups of through holes on the inner side of the filter mesh shell 9 to the outside of the filter mesh shell 9, and the impurities inside the wet sludge accumulate on the inner side of the cylindrical structure of the filter mesh shell 9. Then, the sludge with impurities filtered out flows into the flow velocity pipe 4 and the pressure measuring pipe 6 in sequence through the water outlet holes at the top of the filter pipe shell 1. The electromagnetic flowmeter 7 installed on the flow velocity pipe 4 detects the flow velocity of the wet sludge, and the pressure gauge 5 detects the pressure of the wet sludge at the pressure measuring pipe 6. Then, based on the pressure data and sludge flow velocity data measured by the electromagnetic flowmeter 7 and the pressure gauge 5, the accumulation and filtration situation of impurities inside the filter mesh shell 9 is judged. If the flow velocity measured by the electromagnetic flowmeter 7 is too small and the impurities accumulated in the filter mesh shell 9 are full, resulting in blockage of the filter mesh shell 9, when removing and cleaning the impurities in the filter mesh shell 9, the clamping nut 11 is unscrewed and separated from the clamping bolt 10, and then the clamping bolt 10 is pulled out from the through hole of the retaining disc 2 and the through hole of the right flange of the filter pipe shell 1. Hold the pull rod 3 and drive the retaining disc 2 to move to the right. The retaining disc 2 drives the filter mesh shell 9 screwed to the left end to disengage from the filter pipe shell 1. After the filter mesh shell 9 is completely disengaged from the filter pipe shell 1, manually rotate the filter mesh shell 9 and unscrew the filter mesh shell 9 from the threaded structure of the convex column of the retaining disc 2. Hold the filter mesh shell 9 and slide it to the left. At this time, the outer side of the hanging rack 14 fits against the inner side of the cylinder of the filter mesh shell 9 for moving and scraping. The hanging rack 14 scrapes the impurities adhered inside the filter mesh shell 9 out of the filter mesh shell 9. The filter mesh shell 9 disengages from the hanging rack 14. Then, the filter mesh shell 9 is washed separately with clean water. After cleaning, the threaded structure on the inner side of the cylinder of the filter mesh shell 9 is screwed to the threaded structure of the convex column of the retaining disc 2. Then, the six through holes of the retaining disc 2 are aligned with the six through holes of the right flange of the filter pipe shell 1. The clamping bolt 10 is inserted into the six through holes of the retaining disc 2 and the flange through holes of the filter pipe shell 1 from right to left in sequence. The clamping nut 11 is screwed onto the threaded structure on the outer side of the clamping bolt 10 to complete the fixed installation of the filter mesh shell 9 on the filter pipe shell 1 after cleaning.

As long as they can achieve their beneficial effects, they can be implemented. The above-mentioned flow velocity pipe 4, pressure gauge 5, pressure measuring pipe 6, and electromagnetic flowmeter 7 are all common devices on the market.
