Description

Technical Field

[0002] A heat exchanger device is a device that transfers heat from one medium to another and is widely used in various fields such as energy, chemical industry, metallurgy, and electricity. In the energy field, heat exchangers are widely used in systems such as cogeneration and waste heat recovery to improve energy utilization efficiency and reduce energy waste. At the same time, heat exchangers are also core equipment in refrigeration technology, used to achieve heat exchange between media of different temperatures to achieve refrigeration effects. The pipeline system is an important part of the heat exchanger device, and its main function is to connect the heat exchanger with the heat source and heat sink to achieve heat transfer. The pipeline system is usually composed of pipes, valves, pumps, etc., and its design, installation, and maintenance have an important impact on the performance of the heat exchanger. Existing heat exchanger devices usually adopt a fixed structure, in which the plate is pressed together by a pressing plate to prevent the plate from shifting during the flow of the medium. Although this structure can ensure close contact between the plates and improve the heat exchange efficiency, it also brings about the problem of difficulty in cleaning. In order to solve the cleaning problem, some existing technologies adopt a detachable plate structure, that is, the plate can be separated from the pressing plate by bolts or other connection methods for easy cleaning. However, this structure requires frequent disassembly and assembly, which not only increases the difficulty of operation, but also increases the maintenance cost. The existing heat exchanger device has the following problems in cleaning: First, because the plates are pressed together by the compression plate, the plates are difficult to clean, and dirt and scale are easily accumulated, affecting the heat exchange efficiency; second, even if a detachable plate structure is adopted, it still needs to be frequently disassembled and assembled, which increases the difficulty of operation and maintenance cost; finally, the existing cleaning method is usually manual cleaning, which is labor-intensive, inefficient, and has safety hazards. Therefore, how to design a heat exchanger device that can ensure close contact between the plates and is easy to clean is a problem that needs to be solved urgently in this field.

[0003] To this end, in response to the above problems, the present invention provides a pipeline type heat and cold exchange system and heat exchanger to make up for the shortcomings of the prior art. Compared with the prior art, this technical solution mainly solves: The problem of difficult cleaning of the plates: Since the plates are tightly pressed together by the compression plates, the plates are difficult to clean and easily accumulate dirt and scale, affecting the heat exchange efficiency. The problem of frequent disassembly and assembly: Even if a detachable plate structure is adopted, frequent disassembly and assembly are required, which increases the difficulty of operation and maintenance costs. The cleaning method is traditional, labor-intensive, inefficient, and has safety hazards: The existing cleaning method is usually manual cleaning, which is labor-intensive, inefficient, and also has safety hazards.

[0019] like Figure 1 to Figure 2 As shown, the heat exchanger device assembly includes a fixed bracket 1, a fixed plate 2, a sheet plate 3, a pressing plate 4 and a descaling assembly; a fixed plate 2 is fixedly mounted on one end of the fixed bracket 1, a slidable pressing plate 4 is mounted on the other end of the fixed bracket 1, a plurality of slidable sheet plates 3 are mounted between the fixed plate 2 and the pressing plate 4, and descaling assemblies are arranged on both sides of the pressing plate 4.

[0020] The descaling assembly includes a diverter base 5 and a high-pressure water nozzle 6; diverter bases 5 are provided on both sides of the pressing plate 4, and the diverter base 5 is connected to the water tank through a pipe, and a high-pressure water pump is installed between the two. The diverter base 5 is fixed with multiple high-pressure water nozzles 6 on the side adjacent to the plate 3; when the heat exchanger device operates normally for a period of time, a considerable amount of scale will gradually form on the surface of the plate 3, and the moving device on the upper part of the pressing plate 4 will drive the pressing plate 4 to move along the designed fixed bracket 1, loosen the pressed plate 3, and pass through the designed high-pressure water nozzle 6 and paddle; the purified water in the water tank is The high-pressure water pump drives high-pressure water to enter the diversion base 5, and the high-pressure water is squeezed into the high-pressure water nozzle 6 at a high speed, which will generate a high negative pressure in the air port. The negative pressure will suck the outside air into the high-pressure water nozzle 6. Similarly, when the high-pressure water passes through the blades, the blades will rotate at a high speed. The high-speed rotating blades mix the air and water, and a large number of bubbles are ejected from the high-pressure water nozzle 6 at a high speed to clean both sides of the plate 3. The cleaning of the plate 3 is completed, which is convenient for maintenance personnel to clean and maintain the heat exchanger device, prolongs the working life of the heat exchanger device, and saves costs.

[0021] A plurality of inserts 7 are fixedly installed on both side surfaces of the clamping plate 4, a slidable support rod 8 is installed in the middle of the insert 7, a support base 9 is fixedly installed on the side of the support rod 8 close to the fixed plate 2, a diversion base 5 is arranged on the side of the support base 9 close to the sheet plate 3, a straight tooth groove 10 is designed on the middle part of the support rod 8 close to the middle part of the clamping plate 4, a motor 11 is installed on the side of the middle insert 7, a gear 12 is fixedly installed on the outer ring of the rotating shaft of the motor 11, and the gear 12 and the straight tooth groove 10 are meshed with each other; during operation, the gear 12 is driven to rotate by the motor 11 to drive the meshing straight tooth groove 10, so that the movement of the support rod 8 can drive the support base 9 to move, thereby adjusting the position change of the diversion base 5, which is convenient for the staff to adjust the position of the sheet plate 3 during cleaning, and also convenient for the staff to clean the scattered sheet plates 3, thereby reducing the workload of the staff and improving the work efficiency of the staff.

[0022] Several hydraulic cylinders 13 are fixedly installed inside the support base 9, and the piston rod of the hydraulic cylinder 13 is fixedly connected to the diverter base 5. A plurality of pairs of elastic claws 14 are fixedly installed in the middle of one side of the diverter base 5 near the sheet plate 3, and the side walls of the elastic claws 14 and the side surfaces of the sheet plate 3 are of a sliding combination design. When the system is running, when the support base 9 is driven to the side of the sheet plate 3, the hydraulic cylinder 13 drives the diverter base 5 to approach the sheet plate 3, so that the elastic claws 14 on both sides of the diverter base 5 grip the two side surfaces of the sheet plate 3. During operation, the support rod 8 is driven by the motor 11 to move, driving the gripped sheet plate 3 to separate from the sheet plate assembly, making it convenient for the high-pressure water nozzle 6 to clean the sheet plate 3 gripped by the elastic claws 14, thereby reducing the workload of the staff and improving the work efficiency of the staff.

[0023] The interior of the high-pressure water nozzle 6 is designed with a fixed cross plate 15, and an air port 16 is designed on the cross plate 15. One end of the air port 16 is designed to penetrate the outer wall of the high-pressure water nozzle 6. The side of the cross plate 15 adjacent to the sheet plate 3 is designed with a plurality of bell mouths 17, and the bell mouths 17 are connected to the air port 16 on the cross plate 15. A rotatable paddle 18 is designed and installed in the middle part of the side of the cross plate 15 adjacent to the sheet plate 3; when the system is running, the water flow is driven into the high-pressure water nozzle 6 in the form of high pressure, and a negative pressure phenomenon will be generated in the air port 16, and the outside air will be sucked into the high-pressure water nozzle 6. When the high-pressure water flow passes through the paddle 18, it will drive the paddle 18 to rotate at a high speed, which will mix the air and the water flow together, so that a large number of bubbles are generated inside the high-pressure water flow, and are ejected from the high-pressure water nozzle 6 at a high speed, thereby improving the cleaning intensity and reducing the use of clean water.

[0024] A plurality of elastic ropes 19 are fixedly connected to the inside of the bell mouth 17, and a hollow elastic ball 20 is fixedly installed on the end of the plurality of elastic ropes 19 away from the air port 16, and the outer surface of the hollow elastic ball 20 is designed to be slidably combined with the inner surface of the bell mouth 17; when the system is running, the hollow elastic ball 20 is driven to slide toward the high-pressure water nozzle 6 in the high-pressure water nozzle 6, which can drive the elastic rope 19 to stretch, and then the elastic rope 19 opens the bell mouth 17 to allow outside air to enter the high-pressure water nozzle 6. After reducing the water pressure of the high-pressure water flow, the elastic rope 19 pulls the hollow elastic ball 20, and the hollow elastic ball 20 blocks the bell mouth 17, which reduces the probability of the water flow in the high-pressure water nozzle 6 entering the air port.

[0025] As shown in the attached figure Figure 3-Figure 6 As shown, a corrugated spring piece 21 is fixedly installed on one side of the elastic claw 14 close to the sheet plate 3, and a plurality of elliptical spring strips 22 are fixedly installed between the corrugated spring piece 21 and the elastic claw 14, and an arc-shaped spring piece 23 is fixedly installed between the elastic claws 14 on both sides, and the concave surface of the arc-shaped spring piece 23 can slide with the side surface of the sheet plate 3; when the system is running, the hydraulic cylinder 13 pushes the diverter base 5 to move toward the sheet plate 3 continuously, so that the sheet plate 3 continuously squeezes the arc-shaped spring piece 23 and bends the arc-shaped spring piece 23, which will drive the elastic claws 14 on both sides to squeeze the sheet plate 3, so that the corrugated spring piece 23 continuously squeezes the two sides of the sheet plate 3 and continuously compresses the elliptical spring strips 22, thereby increasing the strength of the elastic claws 14 to grip the sheet plate 3 and ensuring the stability of the sheet plate 3 during cleaning and movement.

[0026] A first airbag 24 is fixedly connected to one side of the elastic claws 14 on both sides near the diverter base 5, and a first airbag 24 is fixedly installed on one side of the elastic claws 14 on both sides near the diverter base 5. A notch 25 is designed on the protruding surface of the elastic claw 14, and a rotatable opening plate 26 is designed on the side of the notch 25 near the diverter base. A second airbag 27 is also fixedly installed between the notch 25 and the opening plate 26, and the two airbags are connected through an air pipe; when the system is running, the elastic claw 14 is inserted between adjacent sheet plates 3. At this time, the hydraulic cylinder 13 will continuously push the diverter base 5 to move toward the sheet plate 3, and the sheet plate 3 will continuously squeeze the first airbag 24, so that the first airbag 24 presses the gas into the second airbag 27 through compression, so that the second airbag 27 gradually expands, and the opening plate 26 is opened, and the sheet plate 3 is opened by the opening plate 26. This design improves the separation efficiency of the sheet plate 3.

[0027] The inner surface of the slot 25 and the recessed surface of the expansion plate 26 are designed with a plurality of magnets 28, and the magnets 28 are attracted to each other by magnetism. When the system is running, after the elastic claw 14 releases the plate 3, the pressure on the first airbag 24 disappears, and the gas in the second airbag 27 is driven back to the first airbag 24. At the same time, the magnets 28 on both sides attract each other under the magnetic effect, driving the expansion plate 26 to rotate into the slot 25 to squeeze the first airbag 24. The purpose of this operation is to improve the efficiency of the gas in the second airbag 27 returning to the first airbag 24.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
