Description

Technical Field

[0001] The utility model relates to the technical field of skid-mounted heat pumps, in particular to a skid-mounted heat pump heating system. Background Art

[0002] Carbon dioxide heat pumps are increasingly widely used in various cooling and heating systems because of their environmentally friendly, high efficiency, low GWP quality, and high energy density. Compared with conventional heat pump systems, carbon dioxide heat pump systems have a higher outlet water temperature, and their one-time outlet water temperature can reach 80°C, which can effectively kill bacteria and viruses in the water; at the same time, the heat pump unit can still guarantee an outlet water temperature of more than 70°C in an environment of minus 20°C, and can be used in places with low ambient temperature; Patent No. CN202223041216.1 announced a skid-mounted carbon dioxide heat pump system, which adopts an overall skid-mounted design and can be moved to any place through transportation equipment (such as a trailer). After the heat pump system is connected to the external water supply and power supply through the electrical connector and the water inlet, it can be used, so as to achieve the effect of on-call, disassembly and assembly at any time, and ready to use; however, since there is no better filtering structure inside the skid-mounted heat pump, if there are more impurities in the water source, these impurities are not processed and are easy to enter the skid-mounted heat pump system, which is easy to cause a certain impact on it. To this end, we propose a skid-mounted heat pump heating system. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a skid-mounted heat pump heating system.

[0004] The technical solution adopted by the utility model to solve the technical problem is a skid-mounted heat pump heating system, comprising a box, a hot water storage tank is installed inside the box, and a pipe seat for water inlet is installed on the surface of the inner side wall of the box, a joint for connection is rotatably installed at one end of the pipe seat away from the box, and a pre-filter is screwed and installed at one end of the joint away from the pipe seat;

[0005] The end of the pre-filter away from the joint is equipped with a disc seat, a ring seat for connection is threadedly installed on the inner side of the disc seat, and a bellows for diversion is rotatably installed on the end of the ring seat away from the disc seat, a pump body is equipped on the end of the bellows away from the ring seat, and a purifier is installed between the pump body and the hot water storage tank.

[0006] By adopting the above technical solution, when the water source enters the skid-mounted heat pump, it is convenient to enter the joint through the guidance of the pipe seat, and then enter the pre-filter through the joint, so that the pre-filter can filter and intercept impurities in the water source, so that the water source can enter the heat pump for use after preliminary treatment, which is convenient to reduce the impact of impurities in the water source. At the same time, the pre-filter is easy to disassemble and assemble, and it is convenient to replace or maintain it.

[0007] After the water source passes through the pre-filter, it can easily pass through the disc seat and enter the ring seat, and can enter the pump body through the guidance of the ring seat and the bellows. The operation of the pump body can easily pressurize the water source and allow the water source to enter the purifier, so as to facilitate further treatment of the water source. Then the water source that has been treated again can easily enter the hot water storage tank for use, which is convenient to reduce the impact of impurities in the water source and make the heat pump operate more stably.

[0008] Specifically, the ring seat and the disc seat have opposite surfaces integrally formed with convex rings that fit and connect with each other.

[0009] By adopting the above technical solution, the two groups of convex rings are connected to each other in a fitting manner, which facilitates improving the tightness of the ring seat and the disc seat after connection.

[0010] Specifically, a solenoid valve is installed on the inner periphery of the pipe seat and between the pump body and the bellows.

[0011] By adopting the above technical solution, the solenoid valve can conveniently control the opening and closing of the pipe seat and the bellows, and is convenient for assisting in the disassembly and assembly of the pre-filter.

[0012] Specifically, an annular groove corresponding to the tube seat is formed on the outer wall surface of the compartment body, and a disc cover is clamped on the inner side of the annular groove.

[0013] By adopting the above technical solution, the disc cover is screwed and installed in the ring groove, which is convenient for disassembly and assembly, and can protect the ring groove and the pipe seat connected to the ring groove.

[0014] Specifically, the outer peripheral surface of the joint, the outer peripheral surface of the disc seat and the outer peripheral surface of the ring seat are all provided with grooves, and there are two groups of grooves.

[0015] By adopting the above technical solution, the multiple groups of grooves on the surfaces of the joint, disc seat and ring seat are convenient for cooperation with the wrench, so as to assist in manipulating the joint, disc seat and ring seat.

[0016] Specifically, a rubber ring is bonded to one side of the ring seat close to the disc seat, and a rubber pad is bonded to one side of the disc cover close to the inner side of the ring groove.

[0017] By adopting the above technical solution, the rubber pad is convenient for improving the tightness of the connection between the disc cover and the ring groove, and the rubber ring is convenient for improving the tightness of the connection between the ring seat and the disc seat, thereby reducing the leakage.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

When the water source enters the skid-mounted heat pump, it is convenient to enter the joint through the guidance of the pipe seat, and then enter the pre-filter through the joint, so that the pre-filter can filter and intercept impurities in the water source, so that the water source can enter the heat pump for use after preliminary treatment, which is convenient to reduce the impact of impurities in the water source. At the same time, the pre-filter is easy to disassemble and assemble, and is convenient for replacement or maintenance.

[0020] 2. The technical solution of the present application is designed through the pump body, disc seat, ring seat, bellows, purifier and heat storage tank. After the water source passes through the pre-filter, it is convenient to enter the ring seat through the disc seat, and can enter the pump body through the guidance of the ring seat and the bellows. The operation of the pump body is convenient for pressurizing the water source and allowing the water source to enter the purifier, so as to facilitate further treatment of the water source. Then, the re-treated water source is convenient to enter the heat storage tank for use, which is convenient to reduce the impact of impurities in the water source, so that the heat pump can operate more stably.
