Description

Technical Field

[0001] This utility model belongs to the technical field of heat exchangers, and particularly relates to a high-efficiency plate heat exchanger. Background Technique

[0002] A plate heat exchanger is a highly efficient heat exchange device widely used in various industrial and commercial applications. It is composed of many thin metal plates stacked together, and multiple heat exchange channels are formed between these plates; by a series of closely arranged metal plates, hot water and cold water flow through different channels respectively, and heat transfer is carried out through the plate surface. The hot water releases heat therein, and the cold water absorbs this heat, thereby achieving the effects of cooling and heating up.

[0003] However, in the existing heat exchanger plate, the size of the water flow channel is fixed, and the flow velocity and flow rate of the water flow depend on the size of the channel. Since the heat exchanger can conduct heat exchange for water at different temperatures, and the heat exchange efficiency between waters at different temperatures is different, therefore, currently, it is basically not convenient to adjust the water flow channel in the plate, and the water flow rate cannot be controlled, thus reducing the heat exchange efficiency of the heat exchanger. Content of the Utility Model

Detailed Description of the Invention

[0021] In order to make the purpose and advantages of this utility model more clear and understandable, the following further describes this utility model in detail with reference to the embodiments. It should be understood that the following text only describes one or several specific implementation manners of this utility model, and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] As Figures 1-5As shown in the figure, an efficient plate heat exchanger includes a fixed pressing plate 1 and a movable pressing plate 2. A number of clamping bolts 3 are assembled between the fixed pressing plate 1 and the movable pressing plate 2. A number of plates 4 are assembled between the fixed pressing plate 1 and the movable pressing plate 2. Two water holes 5 are symmetrically arranged at the front and back of the side wall of the plate 4. A flow guiding groove 7 is arranged between the two water holes 5 on the same side. A receiving groove 8 is arranged on the side wall of the flow guiding groove 7 near the water hole 5. A blocking block 9 is assembled in each receiving groove 8. The corners of the blocking block 9 are all arc chamfers, which is convenient for water flow to flow down quickly along the arc chamfer position. An adjusting component is arranged on the side wall of the blocking block 9.

[0023] Among them, in actual application, the flow rate of the flow guiding groove 7 on the plate 4 can be adjusted according to the heat exchange requirements and the change of water temperature. The flow guiding groove 7 of hot water or cold water can also be adjusted independently to promote the heat exchange efficiency of different water temperatures and improve its application effect.

[0024] As Figure 4 and Figure 5 shown in the figure, the adjusting component includes a screw hole 10 opened on the side wall of the receiving groove 8. The screw hole 10 penetrates through the plate 4. A screw rod 11 is threadedly connected in the screw hole 10. One end of the screw rod 11 is rotatably connected to the blocking block 9. The other end of the screw rod 11 is assembled with a runner 12. Among them, the adjusting structure using the screw rod 11 to act on the blocking block 9 will not loosen due to the impact of water flow and the vibration of the equipment on the one hand. On the other hand, the screw rod 11 has a simple structure, is convenient for maintenance, and has high stability. It can reduce the subsequent bad problems in use and reduce the maintenance cost.

[0025] As Figure 4 shown in the figure, a hexagonal block 13 is fixedly connected to one end of the screw rod 11 away from the blocking block 9. A hexagonal cylinder 14 is fixedly connected to the side wall of the runner 12. The hexagonal block 13 is adapted to the hexagonal cylinder 14.

[0026] Specifically, the runner 12 and the screw rod 11 are connected in a plug-in manner, so that the runner 12 can be disassembled. Its main function is to reserve a motor drive position for later use. When the user needs to change the drive of the adjusting component from manual to electric, the screw rod 11 can be directly connected to the motor by using a coupling to achieve electric control, and the flexibility is relatively high.

[0027] As Figure 4 shown in the figure, a scale 15 is arranged on the side wall of the screw rod 11. By setting the scale 15, when adjusting the protruding position of the blocking block 9, it is convenient to observe the position information of the blocking block 9, so as to achieve the purpose of controllable flow rate in the flow guiding groove 7, which is convenient for the staff to observe and record in real time.

[0028] As Figure 2 and Figure 3 shown in the figure, gears 16 are fixedly connected to the side wall of the screw rod 11, and the gears 16 mesh with each other.

[0029] Specifically, since each screw 11 is equipped with a gear 16, when one of the screws 11 is rotated, all the screws 11 on the same side will be synchronously driven to rotate accordingly. When the screw 11 moves towards the baffle 9, the gear 16 will also move with the screw 11, ensuring that the gears 16 always remain in a meshed state.

[0030] As Figure 2 shown, sealing strips 6 are fixedly connected to the side walls of the plate pieces 4. By providing the sealing strips 6, when the plate pieces 4 are under extrusion pressure, they can have good sealing performance, facilitating the passage of water flow and avoiding water leakage. In addition, the layout trajectory of the sealing strips 6 can be determined according to actual requirements.

[0031] The working principle of this utility model is as follows: When it is necessary to adjust the flow rate of the diversion channel 7, first rotate the runner 12 to drive the screw 11 to rotate through the hexagonal block 13. The screw 11 drives the baffle 9 to extend through the screw hole 10, and the baffle 9 seals the cross-section of the diversion channel 7 to control the water flow rate. While the screw 11 rotates, it drives the gear 16 to rotate. Since multiple gears 16 are meshed with each other, the screws 11 on the same side can rotate synchronously, thereby driving the baffle 9 on the same side to move, achieving synchronous adjustment of the diversion channel 7. By controlling the flow rate of the diversion channel 7, the heat exchange efficiency can be improved, which is beneficial for practical applications.

[0032] The above are only the preferred embodiments of this utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of this utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of this utility model. The structures, devices, and operation methods not specifically described and explained in this utility model, unless otherwise specified and limited, are implemented according to the conventional means in this field.
