However, the pipeline laid at the bottom of the equipment by a traditional sludge pump is in a mouth-shaped structure, so the coverage area is limited, and it takes a long time to pump out the sludge near the bottom of the equipment. Therefore, it is necessary to design a fiber filtration equipment with self-regulation to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] 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.

[0021] Reference Figure 1-4 , a fiber filtering device with self-regulation includes a fiber filter body 1, two external pipes 2, a first sludge pump 5, a liquid level meter 6 and a water storage pipe 11. The first sludge pump 5 is connected to a mouth-shaped sludge pipe. A plurality of first negative pressure pipes 12 are arranged in the fiber filter body 1. A first backwash hood 13 is arranged on the first negative pressure pipe 12. A flow pipe 8 is commonly arranged on the plurality of first negative pressure pipes 12. The fiber filter body 1 is a fiber rotary disc filter in the prior art, which can be an equipment produced by Sichuan Jinlanda Environment. Its filtering principle, backwashing principle, filter disc rotation principle and mud pumping principle are prior art, so no further elaboration is made.

[0022] A sludge extraction mechanism for extracting sludge is provided in the fiber filter body 1, and the sludge extraction mechanism includes a sludge extraction pipe 20 fixedly connected to the fiber filter body 1, and a plurality of sludge extraction ports are opened at the lower end of the sludge extraction pipe 20. One end of the sludge extraction pipe 20 away from the fiber filter body 1 is connected to a second sludge pump 7.

[0023] A cleaning mechanism for cleaning the filter disc inside the fiber filter body 1 is provided inside the fiber filter body 1. The cleaning mechanism includes a plurality of second negative pressure pipes 15 arranged inside the fiber filter body 1. One end of the second negative pressure pipe 15 is connected to a second backwash hood 16. The other ends of the plurality of second negative pressure pipes 15 are commonly connected to a connecting pipe. A backwash pump 19 is provided on the connecting pipe and the circulation pipe 8.

[0024] In the utility model, a plurality of slide rails 17 are fixedly connected inside the fiber filter body 1, and a mounting frame 10 is commonly provided inside two opposite slide rails 17. Two brush plates 14 are fixedly connected to the side walls of the mounting frame 10. The brush plates 14 can sweep out impurities in the bristles when the filter disc rotates, so that the filter disc is cleaned more thoroughly. At the same time, the length of the brush plates 14 is greater than the length of the filter disc, so that impurities at the edge of the filter disc can be cleaned, so that impurities that cannot be cleaned by the first backwash cover 13 whose length is less than the filter disc can be cleaned.

[0025] In the utility model, both side walls of the fiber filter body 1 are fixedly connected with mounting plates 3, the upper end of the mounting plates 3 is fixedly connected with a plurality of hydraulic cylinders 18, and the hydraulic cylinders 18 are fixedly connected with connecting rods 4, so that the mounting frame 10 does not need to be moved manually, thereby improving the degree of automation of the device.

[0026] In the utility model, one end of the connecting rod 4 passes through the lower end of the mounting plate 3, and multiple connecting rods 4 are arranged at equal intervals. The two mounting frames 10 on both sides of the filter disc are connected by the connecting rod 4, and the connecting rod 4 can move the two mounting frames 10 simultaneously.

[0027] In the utility model, a turbidity sensor 9 is provided on one of the external pipes 2, and a controller is provided on the side wall of the fiber filter body 1. The controller is not shown in the figure. When the turbidity sensor 9 detects that the sewage turbidity is large, the backwashing gap of the fiber filter body 1 can be shortened. When the sewage turbidity is small, the backwashing gap of the fiber filter body 1 can be increased, thereby realizing autonomous adjustment. The cross-section of the mud extraction pipe 20 is a serpentine structure, so that more sludge at the bottom of the fiber filter body 1 can be quickly extracted.

[0028] When in use, when the fiber filter body 1 rotates to backwash the filter disc, the two backwash pumps 19 are started, and the backwash pumps 19 perform negative pressure suction, so that the first backwash cover 13 and the second backwash cover 16 can negatively suction the rotating filter disc. Since the first backwash cover 13 and the second backwash cover 16 can clean both sides of the filter disc at the same time, the backwash time of the filter disc is shortened;

[0029] In the sludge pumping stage, by starting the first sludge pump 5 and the second sludge pump 7, the first sludge pipe pumps out the sludge near the mouth-shaped sludge pipe, and the second sludge pump 7 pumps out the sludge near the serpentine sludge pumping pipe 20. Since the sludge pumping pipe 20 covers the bottom of the fiber filter body 1 in a serpentine shape, the sludge at the bottom of the fiber filter body 1 can be pumped out more quickly, thereby improving the practicality of the device;

[0030] When the filter disc rotates, the brush plates 14 on both sides of the filter disc can sweep out the impurities in the filter disc, thereby improving the cleaning effect of the filter disc.

[0031] The above description 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 replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and practical concept of the present invention, which should be covered by the protection scope of the present invention.
