Description

Technical Field

[0001] This utility model relates to the field of wastewater source heat pump technology, specifically a high-efficiency heat exchange device for a wastewater source heat pump system. Background Technology

[0002] A heat exchanger is a device used to transfer hot fluid to cold fluid to meet the requirements of subsequent processes. In a wastewater source heat pump system, heat is transferred to facilitate heat transfer in wastewater treatment.

[0003] In the prior art, impurities tend to accumulate on the surface of the filter screen on the inner wall of the heat exchange device in a wastewater source heat pump system. Due to the excessive amount of impurities inside the wastewater, the accumulation of a large number of impurities can easily affect the heat transfer.

[0004] To overcome the above shortcomings, Chinese patent (publication number CN209894029U) discloses a wastewater self-cleaning heat exchange device for a wastewater source heat pump system. Addressing the problem that sludge and impurities in wastewater adhere to the surface of heat exchange fins, affecting their heat exchange efficiency and thus reducing the overall efficiency of the wastewater source heat pump system, which severely impacts the wastewater treatment rate, the following solution is proposed. It includes a heat exchange tube with heat exchange fins mounted on its inner wall. A fixed circular plate is fixedly installed on the inner wall of the heat exchange tube, and a first through hole is provided on the fixed circular plate. A rotating shaft is rotatably connected to the inner wall of the first through hole. This simple structure prevents heat exchange fins from malfunctioning due to sludge accumulation. The wastewater automatically cleans the heat exchange device, improving the overall efficiency of the wastewater source heat pump system, preventing any impact on the wastewater treatment rate, and is easy to use.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist during their operation. For example, when heat is exchanged in a wastewater source heat pump system, the heat absorption efficiency is low when the heat flows through the inside of the pipes and comes into contact with the heat exchange plates for heat absorption. The heat absorption is incomplete and can easily affect subsequent processes. Utility Model Content

[0006] The purpose of this utility model is to provide a high-efficiency heat exchange device for a sewage source heat pump system, in order to solve the problem mentioned in the background art that when heat flows through the inside of the pipe and comes into contact with the heat exchange plate for heat absorption in a sewage source heat pump system, the heat absorption efficiency is low, the heat absorption is incomplete, and it is easy to affect subsequent processes.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat exchange device for a sewage source heat pump system, comprising a pipe and heat exchange plates installed inside the pipe, characterized in that: a filter screen is bolted to the middle end of the pipe, a drive rod is provided at the middle end of the filter screen, a water wheel plate is installed at the left end of the drive rod, and an auxiliary heat exchange mechanism is provided at the right end of the drive rod.

[0008] Furthermore, two heat exchange plates are provided on the upper and lower sides, and the heat exchange plates are rotatably mounted on rods on the inner wall of the pipe. An adjusting spring is provided between the right end of the heat exchange plate and the inner wall of the pipe.

[0009] Furthermore, the auxiliary heat exchange mechanism is provided with a positioning chamber, and the front and rear ends of the positioning chamber are fixedly installed on the inner wall of the pipe, and the interior of the positioning chamber is provided with inclined blocks.

[0010] Furthermore, a reset spring is provided inside the positioning chamber, and the left and right ends of the reset spring are installed between the inclined block and the positioning chamber, and the elastic force of the reset spring is greater than that of the adjusting spring.

[0011] Furthermore, a cam is installed on the right end of the drive rod, and the cam is correspondingly set with the inclined block. A traction rope is installed on the right end of the inclined block, and the end of the traction rope is fixedly installed on the left end of the heat exchange plate.

[0012] Furthermore, a movable block is fixedly installed at the middle end of the drive rod, and two movable blocks are arranged correspondingly above and below each other. The movable blocks are elongated in shape, and a cleaning brush is installed inside the movable blocks.

[0013] Furthermore, a pressure spring is provided between the left end of the cleaning brush and the interior of the moving block, and the inner side of the cleaning brush is in contact with the surface of the filter screen.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. As the sewage flows, it impacts the water turbine plate, causing it to rotate. This rotation drives the drive rod, which in turn compresses the inclined block inside the positioning chamber. This causes the inclined block to move to the right, squeezing the reset spring. The inclined block then releases the traction rope, reducing the force on the left end of the heat exchange plate. The adjusting spring then pushes the heat exchange plate to rotate, allowing it to absorb heat more thoroughly as the sewage flows through, further improving heat exchange efficiency.

[0016] Furthermore, when the wastewater source heat pump system is exchanging heat, the high-heat wastewater flows from the left side of the pipe to the right side. With the filter screen in place, the filter screen filters out impurities from the wastewater, preventing impurities from adhering to the heat exchange plates at the rear end. At this time, as the wastewater comes into contact with the heat exchange plates, it transfers heat to the heat exchange plates, thereby realizing heat exchange.

[0017] 2. When the drive rod rotates, it drives the moving block to rotate. When the moving block rotates, it drives the inner cleaning brush to rotate. Under the pressure of the pressure spring, the cleaning brush adheres to the surface of the filter screen. As the drive rod rotates, the cleaning brush can clean the impurities on the surface of the filter screen. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: As Figure 1 , Figure 2 , Figure 5 and Figure 6The technical solution shown is a high-efficiency heat exchange device for a sewage source heat pump system. To solve the problem of incomplete heat exchange efficiency, it discloses: a pipe 1 and heat exchange plates 3 installed inside the pipe 1; a filter screen 2 is bolted to the middle end of the pipe 1, and a drive rod 4 is installed at the middle end of the filter screen 2; a water wheel plate 5 is installed at the left end of the drive rod 4, and an auxiliary heat exchange mechanism is installed at the right end of the drive rod 4; two heat exchange plates 3 are arranged on the upper and lower sides, and the rotation of the heat exchange plates 3 is mounted on rods on the inner wall of the pipe 1; and an adjustment spring is provided between the right end of the heat exchange plates 3 and the inner wall of the pipe 1. Spring 14, auxiliary heat exchange mechanism is provided with positioning chamber 10, and the front and rear ends of positioning chamber 10 are fixedly installed on the inner wall of pipe 1. An inclined block 12 is provided inside positioning chamber 10. A return spring 11 is provided inside positioning chamber 10. The left and right ends of return spring 11 are installed between inclined block 12 and positioning chamber 10. The elastic force of return spring 11 is greater than that of adjustment spring 14. A cam 9 is installed on the right end of drive rod 4. The cam 9 is correspondingly set with inclined block 12. A traction rope 13 is installed on the right end of inclined block 12. The end of traction rope 13 is fixedly installed on the left end of heat exchange plate 3.

[0027] When the wastewater source heat pump system is exchanging heat, the high-heat wastewater flows from the left side to the right side of pipe 1, such as... Figure 2 As shown, with filter screen 2 in place, filter screen 2 filters impurities from the wastewater, preventing impurities from adhering to the heat exchange fins 3 at the rear. As the wastewater contacts the heat exchange fins 3, heat is transferred to the heat exchange fins 3, thus achieving heat exchange. Figure 2 and Figure 5 As shown, with the flow of sewage, the sewage impacts the water turbine plate 5, causing it to rotate. The rotation of the water turbine plate 5 drives the drive rod 4 to rotate, which in turn drives the cam 9 on the right end to rotate. When the cam 9 rotates, it presses against the inclined block 12 inside the positioning chamber 10, causing the inclined block 12 to move to the right and press against the reset spring 11. At this time, because the reset spring 11 pushes the inclined block 12 to move to the right, the inclined block 12 causes the traction rope 13 to loosen. At this time, the force on the left end of the heat exchange plate 3 decreases, and the adjusting spring 14 pushes the heat exchange plate 3 to rotate. Figure 6 As shown, heat exchange plate 3 can absorb heat more comprehensively when sewage flows through, further improving the efficiency of heat exchange.

[0028] Example 2: Figures 1-4The technical solution shown, based on Embodiment 1, discloses the following to address the problem of impurities in sewage easily accumulating and affecting flow: a movable block 6 is fixedly installed at the middle end of the drive rod 4, and two movable blocks 6 are arranged correspondingly above and below each other. The movable block 6 is long and narrow, and a cleaning brush 8 is provided inside the movable block 6. A pressure spring 7 is provided between the left end of the cleaning brush 8 and the inside of the movable block 6, and the inner side of the cleaning brush 8 is attached to the surface of the filter screen 2.

[0029] When drive rod 4 rotates, as Figure 4 As shown, with the rotation of the drive rod 4, the drive rod 4 drives the moving block 6 to rotate. When the moving block 6 rotates, it can drive the inner cleaning brush 8 to rotate. At this time, as... Figure 3 As shown, under the pressure of the pressure spring 7, the cleaning brush 8 adheres to the surface of the filter screen 2, and with the rotation of the drive rod 4, the cleaning brush 8 can clean the impurities on the surface of the filter screen 2.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
