Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat pump technology, and in particular to a heat pump wastewater treatment device. Background Technology
[0002] A heat pump is a device that can extract heat from a low-temperature heat source and transfer it to a high-temperature heat source. It works on the principle of the reverse Carnot cycle and can utilize various heat sources such as air, water, and soil. It is a highly efficient and energy-saving heating and cooling equipment, widely used in heating, air conditioning, and hot water supply in homes, businesses, and industries.
[0003] When a heat pump uses wastewater as a cooling source, a wastewater treatment tank is installed in the piping system to pre-treat the wastewater, removing most impurities and protecting the normal operation of the heat pump system. Traditional wastewater treatment tanks mainly rely on filter screens to intercept impurities. Over time, impurities gradually accumulate on the surface of the filter screen, causing the pores to become clogged and reducing filtration efficiency. To prevent unfiltered wastewater from entering the heat pump system, the system needs to be shut down periodically for disassembly and cleaning of the wastewater treatment tank. This shutdown and cleaning operation frequently interrupts the normal operation of the heat pump, shortening its effective operating time. Moreover, frequent disassembly and installation may damage the sealing and overall structure of the wastewater treatment tank, further affecting its filtration effect and service life. To solve the above problems, we have proposed this heat pump wastewater treatment device. Utility Model Content

The lower ends of the first treatment tank 1 and the second treatment tank 2 are both fixedly connected to support bases 4. The first treatment tank 1 and the second treatment tank 2 are respectively connected to a main drain pipe 11 and a drain pipe 10. The inner walls of the first treatment tank 1 and the second treatment tank 2 are both fixedly connected to limit rings 7. The inner walls of the two limit rings 7 are jointly provided with filter screens 8. The mounting base 6 is provided with a sewage discharge mechanism for discharging impurities. The sewage discharge mechanism includes a first suction pump 5 fixedly connected to the bottom of the mounting base 6. The water inlet end of the first suction pump 5 is connected to a first suction pipe 3. The side wall of the mounting base 6 is provided with a controller 21.
[0023] The first processing tank 1 and the second processing tank 2 are equipped with a cleaning mechanism for cleaning the filter screen 8. In this utility model, the cleaning mechanism includes a backwash pipe 22 and two auxiliary drain pipes 13 respectively connected to the first processing tank 1 and the second processing tank 2. The backwash pipe 22 and the auxiliary drain pipes 13 are each equipped with a first valve, and the main drain pipe 11 and the inlet pipe 10 are each equipped with a second valve.
[0024] In this utility model, a second suction pump 14 is fixedly connected to the side wall of the mounting bracket 12. The water inlet end of the second suction pump 14 is connected to a second suction pipe 16. A second water pump 15 is fixedly connected to the side wall of the mounting bracket 12. The water outlet end of the second water pump 15 is connected to a water outlet pipe 18. Multiple nozzles 19 are connected to the water outlet pipe 18. The filter screen 8 can be rinsed through the nozzles 19, so that the water sprayed by the nozzles 19 can flush out the impurities that are blocked and stuck in the filter screen 8, thereby improving the cleaning effect of the filter screen 8. The end of the second suction pipe 16 away from the second suction pump 14 is connected to a suction box 17. The side wall of the filter screen 8 is rotatably connected to a drive rod 20. The impurities on the surface of the filter screen 8 can be sucked away through the suction box 17, thereby reducing the number of times the filter screen 8 needs to be cleaned.
[0025] In this utility model, the side walls of the first treatment tank 1 and the second treatment tank 2 are provided with connecting rings 9, and multiple bolts are provided on the two connecting rings 9. Nuts are provided on the bolts, so that the first treatment tank 1 and the second treatment tank 2 can be disassembled, making it convenient to replace the filter screen 8.
[0026] In this utility model, the side walls of the first treatment tank 1 and the second treatment tank 2 are provided with installation grooves, and glass windows are provided in the installation grooves to facilitate observation of the cleaning status of the filter screen 8 and the accumulation of sludge.

The sewage inlet pipe 10 and the main sewage outlet pipe 11 are respectively connected to the pipe with bolts. After the sewage enters the first treatment tank 1 and the second treatment tank 2, it is intercepted by the filter screen 8. The sludge casting accumulates at the bottom of the second treatment tank 2. By starting the first suction pump 5, the first suction pipe 3 in the second treatment tank 2 will suck in the nearby sludge from the opening of the first suction pipe 3 (shown in the figure) and discharge it from the device. During the process, the cleaning of the filter screen 8 does not require stopping the machine, thereby improving the working time of the heat pump.
[0029] Start the drive assembly of the second suction pump 14 and drive rod 20. The filter screen 8 rotates slowly. The suction force generated in the suction box 17 sucks away the impurities on the surface of the filter screen 8, thereby improving the cleaning effect of the filter screen 8 and reducing the number of times the filter screen 8 needs to be cleaned.
