Description

Technical Field

[0001] This utility model relates to the field of plate compression heat pump technology, specifically a plate compression heat pump with a clamping bolt frame. Background Technology

[0002] Plate compressor heat pumps for swimming pools are high-efficiency and energy-saving devices specifically designed for maintaining pool temperature. Based on the reverse Carnot cycle principle, they use a compressor to drive refrigerant circulation, absorbing low-grade heat energy from the air, water, or soil, and efficiently transferring it to the pool water via a plate heat exchanger, achieving precise water temperature control. Their core advantages are: the plate heat exchanger is made of titanium alloy, offering strong resistance to chlorine corrosion and high heat transfer efficiency; the compressor-driven system is highly energy-efficient, saving more energy than electric heating, and produces no combustion emissions, making it safe and environmentally friendly. The equipment supports modular assembly, adapting to pools of different sizes, and can integrate dehumidification and air conditioning functions, making it an ideal temperature control solution for hotel, club, and home pools.

[0003] The clamping bolt frame of a plate heat pump is a core structural component ensuring the efficient and stable operation of the heat exchanger. It mainly consists of a fixed clamping plate, a movable clamping plate, upper and lower guide rods, clamping bolts, and a rear column. Its working principle is to achieve sealing and pressure bearing of the plate assembly through mechanical fastening: the fixed and movable clamping plates are positioned by the upper and lower guide rods, forming the installation reference for the plate assembly; the clamping bolts adopt a double-threaded design, applying axial pressure to the plate assembly after even tightening, ensuring that the sealing gaskets around the plate perimeter and corner holes are fully compressed, preventing leakage of hot and cold fluids; the rear column provides structural support and enhances overall rigidity. The modular structure facilitates installation and disassembly; the movable clamping plate can slide along the guide rods, enabling quick inspection and cleaning of the plate assembly. In swimming pool heat pump systems, this frame effectively maintains the sealing performance of the plate heat exchanger under frequent start-stop and variable operating conditions, ensuring long-term efficient operation of the heat pump.

[0004] However, in common plate compressor heat pumps, the nuts are prone to loosening under vibration after being tightened, which affects the seal. Therefore, a plate compressor heat pump with a clamping bolt frame is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a plate-type compression heat pump with a clamping bolt frame, which has advantages such as preventing nuts from loosening, and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A plate-type compression heat pump with a clamping bolt frame includes a fixed end plate. Two first screws are fixedly installed on one side of the fixed end plate, and two second screws are fixedly installed on the other side of the fixed end plate. A movable end plate is slidably installed on the surfaces of the first and second screws. Locking nuts are threadedly connected to the surfaces of the first and second screws. Compression springs are sleeved on the surfaces of the first and second screws, and the compression springs are located between the movable end plate and the locking nuts. Two limiting components are provided on one side of the movable end plate.

[0008] The limiting assembly includes two mounting side plates fixedly installed on one side of the movable end plate. A clamping screw is threaded to one side of each mounting side plate. A movable top plate is rotatably mounted on one end of each clamping screw. A limiting block adapted to a locking nut is fixedly installed on one side of each movable top plate. A limiting guide rod is fixedly installed on the top of each movable top plate. The limiting guide rod slides through the mounting side plate. An adjustment knob is fixedly installed on one end of each clamping screw.

[0009] Furthermore, a plurality of plates are provided between the fixed end plate and the movable end plate, and the surfaces of the first screw and the second screw slide through the plates.

[0010] Furthermore, one side of the plate is provided with a first through hole adapted to the first screw, one side of the plate is provided with a second through hole adapted to the second screw, and one side of the plate is provided with corrugations.

[0011] Furthermore, hot end sealing frame gaskets and cold end sealing frame gaskets are alternately arranged between two adjacent plates, and hot inlet pipe, hot outlet pipe, cold inlet pipe and cold outlet pipe are fixedly installed at the four corners of one side of the movable end plate, respectively.

[0012] Furthermore, two hot semi-circular sealing gaskets are fixedly installed inside the hot end sealing frame gasket, and the two hot semi-circular sealing gaskets are respectively aligned with the hot inlet pipe and the hot outlet pipe.

[0013] Furthermore, two thermally round sealing gaskets are fixedly installed inside the hot end sealing frame gasket, and the two thermally round sealing gaskets are respectively aligned with the cold inlet pipe and the cold outlet pipe. Two thermally insulating sealing gaskets are also fixedly installed inside the hot end sealing frame gasket.

[0014] Furthermore, two cold semi-circular sealing gaskets are fixedly installed inside the cold end sealing frame gasket, and the two cold semi-circular sealing gaskets are respectively aligned with the cold inlet pipe and the cold outlet pipe.

[0015] Furthermore, two cold circular sealing gaskets are fixedly installed inside the cold end sealing frame gasket, and the two cold circular sealing gaskets are respectively aligned with the hot inlet pipe and the hot outlet pipe. Two cold isolation sealing gaskets are also fixedly installed inside the cold end sealing frame gasket.

[0016] Compared with the prior art, this utility model provides a plate compression heat pump with a clamping bolt frame, which has the following beneficial effects:

[0017] This plate-type compression heat pump with a clamping bolt frame uses compression springs on the surfaces of the first and second screws, located between the movable end plate and the locking nut. This maintains pressure between the locking nut and the movable end plate. After the locking nut is installed on the surface of the second screw, rotating the clamping screw moves the limiting blocks, causing them to fix the locking nut in place and preventing it from loosening due to vibration. This solves the common problem in plate-type compression heat pumps where the nut easily loosens under vibration after being tightened, affecting the seal. Attached Figure Description

Two limiting components 7 are provided on one side of the movable end plate 4. Tightening the locking nuts 5 compresses the compression springs 6, thus clamping the movable end plate 4.

[0026] The limiting assembly 7 includes two mounting side plates 71 fixedly installed on one side of the movable end plate 4. A clamping screw 72 is threadedly connected to one side of each mounting side plate 71. A movable top plate 73 is rotatably mounted to one end of the clamping screw 72.

[0027] Specifically, tighten the locking nut 5, compress the compression spring 6, press the movable end plate 4, and rotate the adjusting knob 76 so that the limiting block 74 contacts the locking nut 5, locking the locking nut 5 and preventing it from rotating, so that the movable end plate 4 maintains the clamping force.
