Technical Field

[0001] The invention relates to the technical field of waste liquid treatment, in particular to a waste liquid treatment device. Background Art

[0002] Wastewater treatment includes wastewater incineration, organic wastewater treatment or organic industrial wastewater treatment, also known as high-concentration organic wastewater treatment. There are three treatment methods: physical treatment, chemical treatment and biological treatment. Chemical treatment is generally combined with physical processes, also known as physical and chemical treatment. Physical treatment refers to the use of physical or mechanical separation to treat wastewater. Commonly used methods include: filtration, sedimentation, flotation, oil separation and centrifugal separation. Chemical treatment is a wastewater treatment method that separates and removes pollutants in dissolved or colloidal states in wastewater or converts them into harmless substances through chemical reactions and mass transfer. Biological treatment is a wastewater treatment method that converts organic pollutants in wastewater in solution, colloid and fine suspension states into stable and harmless substances through the metabolism of microorganisms.

[0003] When treating industrial waste liquid, steps such as precipitation, filtration and acid-base balance are required. By precipitating the waste liquid, larger impurities in the waste liquid can be precipitated and removed, and then filtered by a filtration device to remove fine impurity particles.

[0016] (2) The waste liquid treatment device, by pressing the handle downward, causes the handle to drive the connecting plate and the filter to move downward, and finally causes the filter to be inserted into the interior of the filter box, and further pushes the second handle, so that the second handle drives the limit plate to be inserted into the through groove, thereby achieving installation limit for the filter, and at the same time, it is convenient for disassembly and later cleaning of the filter, and is very practical.

[0017] (3) The waste liquid treatment device, through the coordinated use of a sedimentation table, an L-shaped plate and a filter screen, first precipitates large particles of impurities in the waste liquid and then filters small particles of impurities, thereby improving the efficiency of impurity removal and also preventing excessive impurities from accumulating on the filter screen and affecting the filtering efficiency of the filter screen.

The rear sides of the two baffles 49 are both in contact with the L-shaped plate 45. The front side contacts and squeezes, and the tops of the two baffles 49 are fixedly connected with the first handle 410. The top of the filter box 3 is slidably connected with a filter screen 5, and the filter screen 5 can filter fine particles in the waste liquid.

A through groove 8 is penetrated on the right side of the connecting plate 6. A mounting block 9 is fixedly connected to the top of the filter box 3 and located on the left side of the connecting plate 6.

The water pump 14 is a prior art, which is controlled by an external switch and electrically connected to an external power supply. The water pump 14 refers to a suction (water) nozzle and an exhaust (water) nozzle with one inlet and one outlet, and can continuously form a vacuum or negative pressure at the inlet.A slight positive pressure is formed at the exhaust nozzle. The principle is that the circular motion of the motor and the mechanical device make the diaphragm inside the pump do reciprocating motion, thereby compressing and stretching the air in the fixed volume pump chamber to form a vacuum (negative pressure). A pressure difference is generated at the pump suction port and the external atmospheric pressure. Under the action of the pressure difference, the gas is pressed (sucked) into the pump chamber and then discharged from the exhaust port. When the water pump 14 is turned off, the waste liquid cannot flow into the filter box 3 through the connecting pipe 13.

The left end of the liquid outlet pipe 15 penetrates the filter box 3 and extends to the inside of the filter box 3. ;

[0028] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0029] During operation, the waste liquid is first introduced into the sedimentation tank 2 through the liquid inlet pipe 12. After the waste liquid is precipitated for a period of time, the water pump 14 is started to extract the waste liquid in the sedimentation tank 2, and then introduced into the filter box 3 through the connecting pipe 13, filtered through the filter screen 3, and discharged through the liquid outlet pipe 15 after the filtration is completed. When it is necessary to remove impurities in the sedimentation table 41, the rotating handle 44 is rotated to make the rotating handle 44 drive the threaded rod 43 to rotate, and at the same time, the threaded rod 43 drives the sedimentation table 41 to slide upward along the outer surface of the fixed rod 42, and finally the sedimentation table 41 rises to the top of the sedimentation tank 2, and further pulls the two first handles 410, so that the first handles 410 drive the two baffles 49 to slide upward along the inner surface of the vertical groove 48, and finally the baffles 49 is separated from the L-shaped plate 45, and under the influence of the elastic force of the spring 47, the spring 47 resets and drives the L-shaped plate 45 to slide forward. The L-shaped plate 45 is further removed, and the impurities on the L-shaped plate 45 can be cleaned. By setting the replacement mechanism 4, the L-shaped plate 45 can be quickly disassembled and assembled, so that the impurities inside the precipitation platform 41 can be quickly cleaned, which improves the work efficiency. By pressing the handle 7 downward, the handle 7 drives the connecting plate 6 and the filter 5 to move downward, and finally the filter 5 is inserted into the inside of the filter box 3, and the second handle 11 is further pushed, so that the second handle 11 drives the limit plate 10 to insert into the through groove 8, so as to achieve the installation limit of the filter 5, and it is also convenient to disassemble and clean the filter 5 later, which is very practical. Through the coordinated use of the precipitation platform 41, the L-shaped plate 45 and the filter 5, the waste liquid is first precipitated with large particles of impurities, and then the small particles of impurities are filtered, which improves the efficiency of impurity removal, and also avoids excessive impurities accumulating on the filter 5, affecting the filtering efficiency of the filter 5.
