DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment: A heat exchange unit for a thermal power station, such as Figure 1-Figure 4As shown, it includes a heat exchanger frame 1, a first clamping plate 101, a second clamping plate 102, a heat exchanger sheet 103, a mounting frame 3, a guide rod 4, a cross connecting frame 5, a sleeve rod 6, a screw rod 7, a handle 8 and a guide rod 9. The heat exchanger frame 1 is used as the basic structure of the whole device, and is mainly used to support and carry components. The first clamping plate 101 is arranged on the top of the heat exchanger frame 1, and the second clamping plate 102 located in front of the first clamping plate 101 is arranged on the top of the heat exchanger frame 1. The heat exchanger sheet 103 is arranged between the first clamping plate 101 and the second clamping plate 102, and the second clamping plate 102 is connected to the first clamping plate 101 by fastening bolts. The fastening bolts are used to ensure the structural stability and the effective contact of the heat exchanger sheet 103; the heat exchanger frame 1 is provided with a mounting frame 3 located in front of the second clamping plate 102, which is used as a mounting carrier for parts and components, and can increase the fixing point for subsequent parts. A guide rod 4 that penetrates the second clamping plate 102 is provided between the upper and lower ends of 3 and the first clamping plate 101, and the second clamping plate 102 forms a sliding fit with the guide rod 4, which has a guiding function to ensure that the second clamping plate 102 can move in a straight line when adjusted and maintain parallel movement. A cross connecting frame 5 is fixedly provided at the middle position of the front side of the second clamping plate 102, and the cross connecting frame 5 can cooperate to uniformly apply force, thereby ensuring the stable disassembly of the second clamping plate 102 and pulling it for synchronous operation. A sleeve rod 6 is provided on the left and right sides of the cross connecting frame 5, and a screw rod 7 is provided on the inner thread of the left sleeve rod 6, and a guide rod 9 is slidably provided on the right sleeve rod 6. The front ends of the guide rod 9 and the screw rod 7 respectively pass through one side of the adjacent mounting frame 3, and the screw rod 7 and the mounting frame 3 are rotatable, and a handle 8 is provided on the front end of the screw rod 7, which makes the rotation of the screw rod 7 more convenient, providing convenience for the operation during disassembly.

[0026] like Figure 2-Figure 6 As shown, it also includes a guide plate 2, a sliding frame 10 and a baffle plate 11. The heat exchanger unit frame 1 is provided with guide plates 2 located on both sides of the bottom of the heat exchange plate 103. The two guide plates 2 are slidably provided with sliding frames 10. The top of the guide plate 2 is provided with a slide rail that is slidably adapted to the sliding frame 10, which can assist the two sliding frames 10 to slide in the left and right directions. A baffle plate 11 is longitudinally arranged on the side where the two sliding frames 10 are away from each other. The upper side positions of the baffle plates 11 are matched in a concave and convex shape to form a matching matching state. When the two baffle plates 11 are closed, they will cooperate with the first clamping plate 101 and the second clamping plate 102 to form a closed structure. At the same time, handles are provided on the side where the two baffle plates 11 are away from each other, so that the movement operation of the baffle plates 11 is more convenient.

[0027] like Figure 4As shown, a glass fiber layer 12 is also included. The inner sides of the two shielding plates 11 are provided with a glass fiber layer 12. The glass fiber layer 12 is resistant to high temperatures and can capture dust in the air. Dust particles will be intercepted by the fibers, thereby reducing the amount of dust in the air.

[0028] like Figure 1 , Figure 4 and Figure 5 As shown, a motor 14 and a spray head 15 are also included. The motor 14 is installed on the top of each of the two baffles 11. The output shaft of the motor 14 passes through the adjacent baffles 11, and the output shaft of the motor 14 is connected to the spray head 15 located on the inner side of the baffle 11, so that the spray head 15 is electrically driven to rotate, thereby achieving a rotating spraying operation of the spray head 15.

[0029] like Figure 1 , Figure 4 and Figure 5 As shown, a water tank 13 is also included. The top of the two baffles 11 is provided with a water tank 13 located on the side of the adjacent motor 14. The water outlet of the water tank 13 is connected to the adjacent spray head 15, so that the spray head 15 can automatically fill with water and realize rotary spraying in coordination with the rotation, thereby achieving a more effective cooling effect.

[0030] When using the device, the staff ensures that the heat exchange unit frame 1 is placed stably, and then slides the two sliding frames 10 to the guide plates 2 on both sides respectively, and then the two shielding plates 11 are closed accordingly to seal the two sides of the heat exchange plate 103. Then the water tank 13 is opened, and then the motor 14 is started. The motor 14 drives the spray head 15 to rotate, and at the same time, the water tank 13 cooperates to fill water into the spray head 15, so that the spray head 15 can perform rotational spraying, and the surface of the heat exchange plate 103 is water-cooled, so that the heat exchange plate 103 drops to a normal temperature to ensure the safety of subsequent operations. Then the disassembly and assembly operation can be started. First, the staff loosens the fastening bolts, and waits for the nuts to disengage. Then the staff can hold the handle 8 and rotate it, thereby driving the screw rod 7 to rotate, and then the sleeve rod 6 is threadedly engaged with the rotation of the screw rod 7, and the sleeve rod 6 is pushed forward The movement of the cross-connecting frame 5 connected thereto is driven, and the guide rod 9 also slides on the right sleeve rod 6. Under the traction of the cross-connecting frame 5, the second clamping plate 102 is driven to slide forward on the guide rod 4, and then separated from the heat exchange plate 103, so that the second clamping plate 102 can be removed therefrom. During this process, there will be a certain amount of dust flying up, and the glass fiber layer 12 on the shielding plates 11 on both sides can capture the dust to ensure a good working environment. Through such operation, the overall disassembly is simpler and more convenient. Compared with manual support and cooperative disassembly, this method not only has uniform force and high safety, but also can effectively improve the disassembly efficiency, and at the same time, to avoid the raising of dust during disassembly; after the above operation is completed, when the machine needs to be used later, the staff needs to slide the sliding frame 10 out of the guide plate 2 to ensure the normal operating environment of the heat exchange plate 103.

[0031] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
