[0031] Please refer to Figure 1 - Figure 5 , the present invention provides a technical solution: a paper pulp residue filtering device, including a residue purification mechanism 1, a dross removal mechanism 2, and a residue sewage injection mechanism 3;

A water pressure regulating valve 16 is provided in the middle of the top of the sewage connection valve 15.

[0036] In this embodiment: an access valve disc 17 is installed at the end of the water pressure regulating valve 16. The end of the access valve disc 17 is connected to a connection sleeve 18. The end of the connection sleeve 18 is installed with a dross removal mechanism 2;

[0037] The dross removal mechanism 2 includes a purification cylinder 21 at the end position of the water pressure regulating valve 16. An adjusting ring 22 is sleeved in the middle of the top of the purification cylinder 21. A driving roller shaft 23 is installed in the middle of the top of the adjusting ring 22. A transmission motor 24 is provided at the top of the driving roller shaft 23.

[0038] By adopting the access valve disc 17 and the purification cylinder 21, the purpose is to deliver a batch of purified water into the purification cylinder 21, and the filter element inside the cylinder rotates under the high-speed operation of the drive motor 24.

[0039] In this embodiment: the output end of the drive motor 24 is in transmission connection with the drive roller shaft 23 at the lower end, the output end of the drive motor 24 is in transmission connection with the rotating cylinder embedded in the purification cylinder 21, a side wall liquid receiving port is opened on the side of the purification cylinder 21, a liquid outlet pipe 26 is communicated with the back of the side wall liquid receiving port, and one end of the liquid outlet pipe 26 is communicated with an arc-shaped conduit 27.

[0040] The main purpose of adopting the side wall liquid receiving port and the liquid outlet pipe 26 is the transfer of liquid.

[0041] The bottom of the purification cylinder 21 is fitted with an access bottom plate 291, and a placement support plate 292 is supported at the bottom of the access bottom plate 291.

[0042] The main purpose of adopting the access bottom plate 291 and the placement support plate 292 is to ensure the replacement and transfer of liquid.

[0043] The end of the arc-shaped conduit 27 is provided with a sleeve 28, the surface of the sleeve 28 is sleeved with a J-shaped pipe 29, the end of the J-shaped pipe 29 is provided with a residue sewage injection mechanism 3, a connecting block 31 is arranged on the side of the residue sewage injection mechanism 3, a fitting backing plate is communicated with the back of the access bottom plate 291, a purification tank 32 is arranged on the back of the fitting backing plate, a pressurizing pipe 33 is installed at the top of the box body of the purification tank 32, a supercharger 34 is installed in the middle of the top of the box body of the purification tank 32, and a control button 35 is arranged on the side of the top of the supercharger 34.

[0044] By adopting the J-shaped pipe 29, it is used for the transfer of sewage and is placed into the purification tank 32 along the pipeline to precipitate impurities in the water again.

[0045] In this embodiment: an impurity storage table 36 is installed on the front surface of the box body of the purification tank 32, a storage tank 37 is installed in the middle of the top of the impurity storage table 36, a liquid discharge conduit 38 is communicated with the top of the storage tank 37, an operation panel 39 is fitted and installed on the surface of the liquid discharge conduit 38, and activated carbon filter pipes 391 are also installed on both side walls of the box body of the purification tank 32.

[0046] The main purpose of adopting the purification tank 32 and the activated carbon filter pipes 391 is to store some activated carbon to remove impurities and odors when the sewage passes through.

[0047] In this embodiment: an activated carbon cotton core is embedded inside the pipe body of the activated carbon filter pipe 391, a second filter membrane filter is fitted and installed inside the purification tank 32, and the bottom of the liquid discharge conduit 38 is hermetically communicated with the storage tank 37.

[0048] The main reason for using the second membrane filter is to further filter out some pollutants in the water in advance and recycle it again after reaching the standard.

[0049] First, step one: extraction of pulp raw materials:

[0050] The separation of the preliminary pulp purified water and pollutants of corresponding sizes is to first apply power to the extraction pump 11 to generate a negative pressure attraction for the sewage. After that, the pollutants in the pulp tank will first pass through the corresponding side slots 14 and transfer to the sewage connection valve 15. The filter membrane structure embedded in the ultrafiltration membrane tube seat 12 component can filter out the pollutants remaining in the water. Finally, after the filtration is completed, the water will enter the specific water pressure regulating valve 16 to regulate the desired water pressure.

[0051] After the filtration is completed and cleaning is required, reverse control the water pump to backwash the filter membrane to flush away the pollutants remaining on the filter membrane (disconnect from the water tank).

[0052] Step two: Taking the purification cylinder 21 and the top adjustment ring 22 as an opportunity, after controlling the drive motor 24 to be energized, it drives the drive roller shaft 23 to rotate, scheduling the pollutants in the water. Finally, the water will transfer from the transparent glass tube 13 to the water pressure regulating valve 16. The advantage of doing this is to ensure the filtration of impurities in the water and then return it to be injected into the pulp tank. According to the rotation of the drive roller shaft 23 controlled by the energization of the drive motor 24, at this time, the filter element inside the purification cylinder 21 will continuously rotate to capture the impurities in the water, and finally transfer to the area of the liquid outlet pipe 26 and extend into the sleeve 28, along the inner wall cavity of the several-shaped pipe 29, and finally schedule the residue sewage to be injected into the mechanism 3.

[0053] Step three: Repurification of the residue sewage injection mechanism 3;

[0054] This stage is to filter out the fine substances in the pulp. Initially, the water will reach the supercharger 34 for secondary pressurization. The pressurized water will be introduced into the pressurization pipe 33 and then transferred to the activated carbon filter pipes 391 on both sides of the purification tank 32 to remove odors. It will be collected again inside the drain conduit 38 and transferred to the storage tank 37. Finally, the sewage stored in the storage tank 37 will achieve the purification of the specific embedded sewage.
