Description

Technical Field

[0001] The utility model relates to the field of heat pump heat exchange, and more specifically to a magnetic suspension geothermal heat pump heat exchange device. Background Art

[0002] Geothermal heat pump uses ground energy (soil, groundwater, surface water, low-temperature geothermal water and tail water) as the cooling source for summer cooling and the low-temperature heat source for winter heating. It is also an air-conditioning system that realizes heating, cooling and domestic hot water. The whole heat pump system will use a corresponding compressor to compress the air. In order to improve the working efficiency and reduce the friction inside the compressor, magnetic bearings will be used in the prior art to reduce the friction. Corresponding heat exchange equipment is needed in the heat pump system. The common heat exchanger is to let the refrigerant flow through the inside of the heat exchanger through a U-shaped tube, and pass cooling water into the inside of the heat exchanger to achieve the heat exchange effect. Due to the flow of liquid inside the heat exchanger, a large amount of impurities will accumulate on the inner wall of the heat exchanger after a period of use. The heat exchanger needs to be cleaned regularly. Therefore, the two ends of the heat exchanger are mostly sealed by the cooperation of end covers and bolts, and the shell is supported by the support seat in a suspended state. Therefore, when installing the end cover, a crane is needed to lift the end cover to the same height as the heat exchanger shell for installation, which makes the installation extremely inconvenient.

[0003] In order to ensure that a sealing gasket is provided between the sealing end cover and the shell, when installing multiple bolts, they are screwed together in time according to the butt joint, and the sealing gasket inside thereof may be deformed due to uneven force. Utility Model Content

A sealing end cover 2 is provided at one end of the heat exchanger shell 1, and a water inlet end cover 3 is provided at the other end of the heat exchanger shell 1. The sealing end cover 2 and the water inlet end cover 3 are fixed to the two ends of the heat exchanger shell 1 by the cooperation of flanges and bolts, so that a sealed space is formed inside the heat exchanger shell 1 except for the water inlet and outlet pipes to prevent water leakage. A plurality of U-shaped tubes are provided inside the heat exchanger shell 1. The water inlet end cover 3 is divided into two areas, which are distributed in the U-shaped tubes and connected. The bottom of the heat exchanger shell 1 is symmetrically provided with A main support seat 4 is provided, and the bottom of the main support seat 4 is fixed to the ground by bolts so that the heat exchanger shell 1 is in a suspended state, so as to facilitate the docking control of the bottom drainage pipe. Two auxiliary support seats 5 are provided, and the two auxiliary support seats 5 are respectively placed under the sealing end cover 2 and the water inlet end cover 3. The auxiliary support seats 5 are placed on the side away from each other of the main support seat 4. An arc-shaped docking plate 51 is provided on the top of the auxiliary support seat 5. The sealing end cover 2 and the water inlet end cover 3 are respectively adapted to the inside of the two arc-shaped docking plates 51. The arc-shaped docking plate 51 is larger than a semicircle so as to preliminarily fix the end cover after it is installed.

[0025] Please refer to Figure 2 and Figure 3 As shown, the auxiliary support seat 5 is symmetrically provided with cross bars 53 at one end close to the main support seat 4, and the two cross bars 53 both penetrate the main support seat 4. The upper surface of the cross bars 53 is evenly provided with convex teeth 54. A rotating shaft 41 is installed inside the main support seat 4 through a bearing. The rotating shaft 41 and the cross bars 53 are vertically distributed. A control wheel 42 is provided at the end of the rotating shaft 41. The control wheel 42 is placed on the outside of the main support seat 4 to facilitate external control of the rotating shaft 41. The rotating shaft 41 is placed above the cross bars 53. Two gears 43 are installed on the surface of the rotating shaft 41. The gears 43 are meshed with the convex teeth 54, and then the movement of the two cross bars 53 can be synchronously controlled to ensure the stability of the end cover when moving, and control the end cover and the end of the heat exchanger shell 1 to approach or move away from each other.

[0026] Among them, locking bolts 52 are symmetrically screwed on both sides of the arc-shaped docking plate 51 to achieve the fixation of the water inlet end cover 3 or the sealing end cover 2 and the auxiliary support seat 5.

[0027] Please refer to Figure 2 and Figure 4As shown in the figure, an installation groove 44 is formed on one side of the main support base 4 close to the control wheel 42. The rotating shaft 41 penetrates through the installation groove 44. A ratchet wheel 49 is installed on the surface of the rotating shaft 41. The ratchet wheel 49 is placed inside the installation groove 44. A storage hole 45 is formed at the top of the installation groove 44. A wedge-shaped slider 46 is vertically and slidably installed inside the storage hole 45. The bottom of the wedge-shaped slider 46 cooperates with the ratchet wheel 49. Through the cooperation of the two, when no external force is applied, the rotating shaft 41 can only move in a single direction, thereby ensuring the contact force between the end cover and the heat exchanger housing 1. A fixing bolt 48 is arranged on the outer side of the wedge-shaped slider 46. The fixing bolt 48 penetrates through the side surface of the main support base 4, which is convenient for controlling the wedge-shaped slider 46 externally.

[0028] Among them, a spring 47 is arranged inside the storage hole 45. The bottom of the spring 47 is in contact with the upper surface of the wedge-shaped slider 46. The elastic force of the spring 47 is used to make the wedge-shaped slider 46 always receive a downward force, thereby keeping the retainer always cooperating with the ratchet wheel 49.

[0029] Please refer to Figure 1 As shown in the figure, lifting lugs 11 are symmetrically arranged on both sides of the upper surface of the heat exchanger housing 1 to facilitate the installation of the heat exchanger housing 1.

[0030] Working principle: First, due to the existence of the spring 47, the wedge-shaped slider 46 always has a downward force to ensure that the bottom of the wedge-shaped slider 46 always remains in contact with the ratchet wheel 49. Through the cooperation of the two, the rotating shaft 41 can only rotate in a single direction. The rotation direction ensures that the outer main support base 4 can be controlled to approach, but not to move away. During installation, first, the heat exchanger housing 1 is fixed by the main support base 4, and the water inlet end cover 3 and the sealing end cover 2 are respectively placed on the arc-shaped docking plate 51. Then, the sealing end cover 2 or the water inlet end cover 3 is fixed by the locking bolts 52 on both sides. Then, the control wheel 42 is rotated to drive the rotating shaft 41 to rotate. Through the mutual cooperation of the gear 43 and the convex teeth 54, the cross bar 53 is controlled to move. Through the movement of the cross bars 53 on both sides, the auxiliary support base 5 is pulled, and then the sealing end cover 2 or the water inlet end cover 3 is moved to make the docking flanges correspond to each other, so as to facilitate the installation and docking.

[0031] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
