Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to sewage resource utilization equipment. Background Art

[0002] my country's rural areas produce more than 8 billion tons of domestic sewage every year, while 96% of villages have no drainage channels and sewage treatment systems, and domestic sewage is discharged at will; the wanton discharge of untreated domestic sewage has seriously polluted the rural ecological environment, directly threatening the health of the vast number of farmers and the rural economic development; on the one hand, untreated domestic sewage flows into low-lying rivers, lakes, ponds and other surface water bodies, seriously polluting various water sources; on the other hand, domestic sewage is also the source of disease transmission and spread, which can easily cause the occurrence and spread of infectious diseases, endemic diseases and zoonotic diseases in some areas.

[0003] A search by a new information search agency revealed that announcement number CN213266182U discloses a rural domestic sewage resource recycling and treatment device, including a filter tank, a contact oxidation tank and an ecological breeding tank; the water inlet pipe collects domestic sewage to the filter tank, and performs preliminary filtration through a filter baffle. The filter baffle and the mounting bracket are a movable connection structure, which is convenient for replacement and cleaning. The domestic sewage enters the filter tank and enters the contact oxidation tank after being filtered through multiple layers of filter fillers; the filler is submerged in water, and a blower is used to aerate and oxygenate the bottom of the filler. After the air escapes, the wastewater returns to the bottom of the pool from top to bottom in the filter material compartment, and the treated wastewater is passed into the ecological breeding pond, where economic fish species such as catfish and black carp can be raised; the moving block is driven up by a lifting motor, and the oxidation filler layer is taken out and sterilized at high temperature. The sterilized filler can be introduced into the ecological breeding pond as a breeding base, or it can be spread around the ecological breeding pond as a crop production base.

[0004] The above technology discloses a rural domestic sewage resource recycling and treatment equipment, which realizes the treatment and reuse of sewage through sewage filtration, aeration and oxygenation, etc., but still has the following deficiencies during use: 1. The filter baffle arranged in the filter tank can filter and intercept the solid residue in the sewage in advance to prevent a large amount of solid residue from entering the subsequent treatment steps. However, as the filtration progresses, a large amount of solid residue will accumulate on the filter baffle and cause blockage, requiring manual cleaning and removal; the solid residue cannot be discharged quickly and automatically and the filter baffle cannot be dredged. A part of the solid residue will be blocked in the filter pores of the filter baffle itself, affecting the water flow effect. The convenience and automation of residue cleaning and dredging are not ideal. In view of this, the present application proposes a sewage resource utilization equipment based on the improvement.

The left side of the blocking block 3 movably passes through the left side of the filter tank 1 and is fixedly connected to a sealing plate 4, wherein the left inner wall of the filter tank 1 is provided with a movable through-hole 16 that is in contact with the outer side of the blocking block 3, which plays the effect of allowing the blocking block 3 to movably pass through. The right side of the sealing plate 4 is bonded and fixed with a sealing gasket, and the sealing gasket is movably sleeved on the blocking block 3, and the right side of the sealing gasket is tightly contacted with the left side of the filter tank 1. The set sealing gasket plays the effect of sealing between the sealing plate 4 and the filter tank 1, realizing the sealing of the left side of the movable through-hole 16.

The filter tank 1 is provided with two T-shaped guide rods 14 on the right inner wall of the filter tank 1, and two transverse guide holes are provided on the left inner wall of the filter tank 1, which are respectively slidably fitted with the outer sides of the corresponding T-shaped guide rods 14, and play the role of guiding the T-shaped guide rods 14 to slide horizontally. The sewage is first transported into the rectangular tube 2 by the water inlet pipe 101, and the sewage is filtered out downward by a plurality of filter holes 201, and the solid impurities are filtered and collected in the rectangular tube 2.

[0031] The method of use of this embodiment is as follows: when in use, sewage first enters the rectangular tube 2 through the water inlet pipe 101, and then is filtered downward through the multiple filter holes 201. The solid residue is filtered and collected in the rectangular tube 2, and the sewage filtered downward enters the filter tank 1 for treatment. The other specific components and structures of the sewage resource utilization equipment body and the sewage treatment and utilization principles are prior art. In addition, this composition and technology have also been disclosed in the above-mentioned prior art CN213266182U, which is the same as it, and will not be further elaborated on.

[0032] When it is necessary to clean and discharge the solid slag and dredge the filter hole 201, the personnel starts the driving motor 9 and turns on the air pump 10 in the forward direction. The driving motor 9 drives the screw 5 to rotate. The rotation of the screw 5 drives the internal threaded sleeve 6 to move to the left. The internal threaded sleeve 6 drives the blocking block 3 and the sealing plate 4 to move left to unseal the rectangular tube 2. The sealing plate 4 drives the two T-shaped guide rods 14 to move to the left. At the same time, the internal threaded sleeve 6 drives the slag pushing plate 7 to move left to push the solid slag to the left and discharge it. The slag pushing plate 7 drives the two baffles 8 to move left. The left-moving baffle 8 temporarily blocks the bottom end of the water inlet pipe 101 to the left during slag discharge, avoiding the phenomenon of sewage continuing to enter during slag discharge and causing a large amount of external discharge, thereby achieving the effect of convenient, rapid, automatic and stable slag discharge, without the need for personnel to manually clean and remove the solid slag, thereby improving the convenience and automation of slag cleaning;

[0033] When the filter press 10 is turned on, the air is supplied to the movable box 12 through the transverse pipe 11, and the air is blown upward through the multiple cleaning pipes 13. When the sealing plate 4 moves to the left, it will drive the cleaning pipe 13 to move left in turn through the air pump 10, the transverse pipe 11 and the movable box 12. The multiple cleaning pipes 13 that move left and blow upward are used to realize the upward back-blowing cleaning and dredging of multiple filter holes 201, thereby reducing the phenomenon that the filter holes 201 are blocked. The filter holes 201 are automatically back-blown and dredged during slag cleaning, which is convenient for the subsequent stable filtering work and improves the convenience of dredging and the degree of automation. After the slag cleaning and dredging is completed, the air pump 10 is turned off and the drive motor 9 is started in the reverse direction. Similarly, the movement direction of the drive motor 9 is completely opposite to the above-mentioned forward start-up. At this time, the sealing plate 4 is converted to move back to the right and seal the left part again. At this time, the slag pushing plate 7 is converted to move back to the right and drive the baffle 8 to release the blockage of the bottom end of the water inlet pipe 101 to the right, so that sewage can enter again for filtering.
