Description

Technical Field

[0001] The utility model relates to the technical field of biological filter tanks, in particular to a special emergency cleaning device for filter tanks. Background Art

[0002] After the biofilter has been running for a period of time, due to the byproducts produced by the normal growth and metabolism of microorganisms and the aging and shedding of the biofilm, as well as excessive suspended solids in the influent, the filter material of the biofilter will be blocked, resulting in a decrease in the water flow capacity of the biofilter. Application No. 201920740902.7, entitled "A Utility Model Patent for an Anaerobic Biofilter That Is Easy to Clean", discloses an anaerobic biofilter that is easy to clean, including a shell, a water pipe, a filler body and a motor, a filler body is arranged inside the shell, a second bearing is installed on the outer wall of the upper and lower ends of the filler body, the second bearing is connected to the inner wall of the shell through a support frame, a water pipe is embedded and installed inside the shell, and the water pipe corresponds to the position of the filler body, the water pipe runs through one side of the inner wall of the shell and is provided with nozzles evenly and equidistantly distributed, a first bearing is embedded and installed at the center of the upper surface of the shell, a motor is installed at the upper end of the shell, a rotating shaft is installed on the lower surface of the motor, and the rotating shaft runs through the first bearing and is connected to the filler body. However, the technical solution has the problem of uneven installation of the cleaning device, which makes it impossible to clean the local area of ​​the filter. The area of ​​the filter that cannot be cleaned for a long time becomes more and more blocked until the blocked area of ​​the filter is completely blocked and all water flows through other areas of the filter. This reduces the effective filter volume of the biofilter, reduces the pollutant removal capacity of the biofilter, and increases the effluent index, affecting the normal operation of the biofilter. At present, in response to the uneven cleaning device, it is necessary to manually dig out the filter material in the blocked area for cleaning. The working environment of manual cleaning is poor, and the space is limited. There are risks such as toxic and harmful gases and lack of oxygen, which makes manual cleaning very difficult.

[0016] The present invention will be further described in detail below in conjunction with the embodiments.

[0017] refer to Figure 1 and Figure 2 The utility model provides a special emergency cleaning device for a filter tank, comprising a water tank 1, a high-pressure pump 2, a high-pressure hose 3, an air compressor 4, a high-pressure air pipe 5, a flushing pipe 6 and a high-pressure nozzle 7.

[0018] The high-pressure pump 2 is provided with a water inlet and a water outlet, the water inlet is connected to the water tank 1 through a pipeline, and the water outlet is connected to one end of the high-pressure hose 3. The other end of the high-pressure hose 3 is connected to the high-pressure water inlet 61, and the air compressor 4 is connected to the high-pressure gas inlet 62 of the flushing pipe 6 through a pipeline.

[0019] The flushing pipe 6 is provided with a high-pressure water inlet 61, a high-pressure gas inlet 62 and a plurality of nozzle mounting holes 63 arranged in the longitudinal direction. The high-pressure water inlet 61 is located at the top opening of the flushing pipe 6, and the high-pressure gas inlet 62 is located at the side at nine-tenths of the height of the flushing pipe 6. The height of the high-pressure gas inlet 62 is lower than that of the high-pressure water inlet 61.

[0020] The bottom end of the flushing pipe 6 is blocked, and a plurality of rows of nozzle mounting holes 63 arranged in the longitudinal direction are evenly distributed on the circumferential side surface above the bottom end of the flushing pipe 6 , that is, within a range of one quarter of the height of the flushing pipe 6 .

[0021] There are multiple high-pressure nozzles 7, and the multiple high-pressure nozzles 7 are fixedly installed in the multiple nozzle installation holes 63 in a one-to-one correspondence. The spray direction of the high-pressure nozzle 7 is obliquely upward, and the angle between its spray direction and the flushing pipe 6 is 45° to 60°. The flushing pipe 6 is a seamless steel pipe, and the spray pressure of the high-pressure nozzle 7 is 200 bar.

[0022] When the utility model is used, a flushing pipe equipped with a high-pressure nozzle is inserted into the blocked area of ​​the biological filter 8, and a high-pressure pump or air compressor is turned on. The cleaning water or air in the water tank is transported into the flushing pipe through the high-pressure pump and the high-pressure hose or pipeline, and the cleaning water or air is sprayed obliquely upward through the high-pressure nozzle to disperse the sediment of the filter material and bring it upward to the surface of the biological filter with the water flow. The staff inserts the flushing pipe into the filter material on the surface of the filter at the bank of the biological filter to start cleaning. As the cleaning process progresses, the flushing pipe is inserted downward to gradually deepen the cleaning depth until the filter material at the bottom of the filter is cleaned. Then the flushing pipe is moved upward from the bottom layer to clean the surface filter material upward, and finally the suspended matter flushed out is discharged from the biological filter through the backwashing system of the biological filter itself. During the cleaning process, the filter does not need to be drained, and personnel do not need to enter the internal space of the filter to work, and the water-passing capacity of the partially blocked filter material can be efficiently restored.

[0023] The above are only some embodiments of the present invention. For ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
