Description

Technical Field

[0001] The utility model relates to the technical field of waste liquid treatment devices, in particular to a waste liquid treatment device for a city garbage transfer station. Background Art

[0002] Urban waste transfer stations are facilities used to temporarily store and transfer urban domestic waste. They are usually located at the edge of the city or far away from residential areas. After the waste is sent here, it will be temporarily piled up or sorted and sorted before being transferred to treatment facilities such as landfills or waste incineration plants. This can reduce the pressure on urban waste treatment facilities and facilitate centralized management and transportation of waste.

[0003] After searching, a Chinese patent discloses a sewage treatment device for a city garbage transfer station (authorization announcement number CN218188379U), which belongs to the technical field of sewage treatment equipment, including "a box body, a fixed seat is fixedly installed at the top of the box body, a conical groove is opened in the center of the top of the fixed seat, and a drive motor is fixedly installed at the center of the top of the box body, and the drive motor is fixedly connected to the main shaft through the output end at the bottom thereof". Although this patented technology can separate sewage from garbage.

[0004] However, in the actual application of this patented technology, the squeezed garbage falls into the top of the net. As the squeezing work continues, the sewage will also fall onto the surface of the squeezed garbage, causing the garbage to re-absorb the sewage, thereby reducing the separation effect of solid garbage and wastewater. In response to the above problems, the inventor proposed a waste liquid treatment device for a municipal garbage transfer station to solve the above problems. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0020] Embodiment: As Figures 1-4 shown, the present invention provides a waste liquid treatment device for an urban waste transfer station, including a body 1. A compression groove 2 is opened inside the body 1. Filter plates 3 are fixedly installed on both sides of the compression groove 2. A first hydraulic cylinder 4 is fixedly installed on one side of the body 1. The piston rod of the first hydraulic cylinder 4 extends into the compression groove 2 and is fixedly connected to a push plate 5. Collection boxes 6 are fixedly connected to both sides of the body 1. A first connecting pipe 7 is fixedly connected between one sides of the bottoms of the two collection boxes 6. The first connecting pipe 7 communicates with the interiors of the two collection boxes 6 respectively.

[0021] Horizontal pipes 8 are fixedly connected to the mutually remote sides of the collection boxes 6. Nozzles 9 are fixedly installed at equal intervals inside the horizontal pipes 8. The front ends of the nozzles 9 extend into the collection boxes 6. A second connecting pipe 10 is connected between one ends of the two horizontal pipes 8. A water pump 11 is fixedly installed at the top of the body 1. The output end of the water pump 11 is fixedly connected to the second connecting pipe 10. The input end of the water pump 11 is fixedly connected to a liquid inlet pipe 12. The liquid inlet pipe 12 is connected to an external cleaning water source.

[0022] By adopting the above technical solution, the cleaning water is pumped out through the liquid inlet pipe 12 by the water pump 11 and is conveyed to the inside of the horizontal pipe 8 through the second connecting pipe 10, and is sprayed onto the surface of the filter plate 3 through the nozzles 9, so as to clean and dredge the surface of the filter plate 3, thereby restoring the filtering performance of the filter plate 3.

[0023] Second hydraulic cylinders 13 are fixedly installed on both sides of the body 1 close to the collection boxes 6. A baffle plate 14 is arranged at the top of the body 1. The bottom end of the baffle plate 14 extends into the body 1 movably and abuts against the bottom end of the inner wall of the body 1. The piston rods of the second hydraulic cylinders 13 are fixedly connected to both sides of the baffle plate 14 respectively.

[0024] By adopting the above technical solution, through the telescopic movement of the piston rod of the second hydraulic cylinder 13, the baffle 14 is pushed to move vertically. When it is necessary to extrude municipal waste, the baffle 14 is closed. After the municipal waste is extruded, by opening the baffle 14, the municipal waste is pushed out from the inside of the compression tank 2.

[0025] A feed hopper 15 is fixedly connected to the top end of the machine body 1, and the feed hopper 15 communicates with the inside of the compression tank 2.

[0026] By adopting the above technical solution, by setting the feed hopper 15, it is convenient to pour municipal waste into the inside of the compression tank 2.

[0027] One end of the machine body 1 away from the first hydraulic cylinder 4 is fixedly connected with an inclined panel 16, and the top end of the inclined panel 16 is on the same plane as the bottom end of the compression tank 2.

[0028] By adopting the above technical solution, by setting the inclined panel 16, it is convenient for the municipal waste to slide down after coming out of the inside of the compression tank 2.

[0029] A switch valve 17 is installed on the first connecting pipe 7.

[0030] By adopting the above technical solution, by setting the switch valve 17, it is convenient to control the outflow of the water body inside the collection box 6.

[0031] Working principle: When treating the waste liquid in municipal waste, it is necessary to perform a physical separation operation on the waste and wastewater in advance. By pouring the municipal waste from the top end of the feed hopper 15 into the inside of the compression tank 2, and then by the elongation of the piston rod of the first hydraulic cylinder 4, the municipal waste is pushed to move to one side of the baffle 14. By using the cooperation between the filter plate 3 and the baffle 14, during the compression process, the wastewater in the municipal waste overflows through the filter plate 3 and flows into the inside of the collection box 6, and is discharged through opening the first connecting pipe 7;

[0032] After the filter plate 3 is used for a period of time, it will become blocked. The cleaning water is pumped out through the liquid inlet pipe 12 by the water pump 11 and is conveyed to the inside of the horizontal pipe 8 through the second connecting pipe 10, and is sprayed onto the surface of the filter plate 3 through the nozzle 9, so as to clean and dredge the surface of the filter plate 3, so that the filter plate 3 restores its filtering performance;

[0033] For the compressed waste, by the elongation of the piston rod of the second hydraulic cylinder 13, the baffle 14 is pushed to move upward to open the baffle 14. Then, by the elongation of the piston rod of the first hydraulic cylinder 4, the municipal waste is pushed out to the inside of the compression tank 2.

[0034] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these modifications and variations.
