DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0026] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 7The detachable plate heat exchanger includes a fixed splint 1 and a movable splint 5. The fixed splint 1 is provided with two water inlets and two water outlets on the left side. The water inlets and the water outlets are respectively distributed in the upper and lower parts of the fixed splint 1. The water inlets and the water outlets on the fixed splint 1 are both provided with filter screens 18. The filter screen 18 is used to filter the fluid entering the water inlet and flowing out of the water outlet. The fixed splint 1 is provided with a fixed plate 17 at the bottom. The fixed plate 17 is used to facilitate the installation of the fixed splint 1 on the equipment. The fixed splint 1 and the movable splint 5 are provided with guide sleeves 3 at the four corners, and the two adjacent front and rear guide sleeves 3 are threadedly provided with a bidirectional screw 2, and the bidirectional screw 2 is threadedly provided with a nut 4, and the movable splint 5 can be tightened and loosened by rotating the nut 4, and two sliding rods 7 symmetrically distributed up and down are clamped on the fixed splint 1, and the movable splint 5 slides horizontally on the sliding rod 7, and the movable splint 5 can cooperate with the fixed splint 1 to clamp and release by moving the sliding rod 7 left and right. The heat exchange plate group is loosened, and the two sliding rods 7 are fixedly connected to the bracket 6 by welding. A heat exchange plate 10 is arranged on the sliding rod 7. The surface of the heat exchange plate 10 is provided with a corrugated shape, which can enhance heat transfer and improve pressure resistance. When in use, the heat exchange plate 10 is loosened by moving the movable splint 5 to the left, and then the sliding rod 7 and the fixed splint 1 are separated to realize the disassembly operation of the heat exchange plate 10. The fixed splint 1 is provided with two guide rods 8 which are symmetrically distributed front and back. The movable splint 5 slides horizontally on the guide rods 8, and the movable splint 5 is guided by the guide rods 8 to ensure the stable movement of the movable splint 5. An elastic member 9 for resetting the movable splint 5 is sleeved on the guide rod 8. The two ends of the elastic member 9 are respectively connected to the movable splint 5 and the fixed splint 1. Rubber gaskets 19 are embedded at the four corners of the heat exchange plate 10. The fluid flowing inside the device is guided by the rubber gasket 19, and the heat exchange plates 10 are sealed.

[0027] Initially, the elastic member 9 is in a compressed state. By screwing the nut 4 to disengage it from the bidirectional screw 2, the pressure on the movable splint 5 disappears. Under the action of the elastic force, the elastic member 9 is restored from the compressed state to push the movable splint 5 away. The movable splint 5 no longer clamps the heat exchange plate 10, and the heat exchange plate 10 can be removed, which is convenient for subsequent replacement, maintenance and cleaning operations.

[0028] Example 2: Based on Example 1, please refer to Figure 4 and Figure 5Guide blocks 13 are provided on both sides of the water inlet and the water outlet on the fixed splint 1, and a one-way screw 12 is threadedly provided on the guide block 13. The inner ends of the two adjacent one-way screws 12 are rotatably provided with a clamping block 11. By rotating the one-way screw 12, the clamping block 11 can be pushed inward to clamp the pipe connected to the water inlet and the water outlet to prevent it from falling off, and the clamping block 11 is arc-shaped, which can better clamp the pipe. The outer ends of the two adjacent one-way screws 12 are fixed with a hand wheel 14 by welding.

[0029] When the device is docked with the pipeline, the hand wheel 14 is rotated to make the one-way screw 12 drive the clamping block 11 to move outward. After the device is docked with the pipeline, the hand wheel 14 is rotated in the opposite direction to make the clamping block 11 return inward to clamp and fix the pipeline, thereby preventing it from falling off and preventing the pipeline from being washed off by excessive water pressure during operation.

[0030] See also Figure 6 The front and rear sides of the fixed clamping plate 1 are fixedly connected with sliders 16 by welding, and the sliders 16 are slidably provided with slide rails 15. Through the slide rails 15, the fixed clamping plate 1 can be moved up and down to achieve height adjustment.

[0031] After the device is installed on the equipment, the slide rail 15 can be used to pull the fixed clamping plate 1 up and down to adjust the height, so as to facilitate docking with pipelines of different heights for use.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
