Description

Technical Field

[0001] The utility model relates to the technical field of plate heat exchangers, in particular to a plate heat exchanger with a deep flow channel and a high flow rate. Background Art

[0002] The plate heat exchanger is a high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. The plate heat exchanger is an ideal device for liquid-liquid and liquid-steam heat exchange. The plate heat exchanger is a detachable heat exchange device composed of many corrugated heat transfer plates, which are compressed by rubber gaskets at a certain interval. The four corner holes on the plate form the distribution pipes and drainage pipes of the fluid. The two heat exchange media flow into their respective flow channels, forming countercurrent or parallel flow through each plate for heat exchange.

[0003] After long-term use, scale will form on the surface of the plate of the plate heat exchanger. If it is not cleaned in time, it will affect the flow channel between the plates, reduce the liquid flow rate, and reduce the heat exchange efficiency. The current plate heat exchanger does not have an automatic cleaning function. If the plate needs to be cleaned, the plate needs to be removed, but the overall disassembly and installation process is relatively complicated. Professional cleaning fluid can also be used, but the scale impurities cleaned are not convenient to discharge, so there are certain disadvantages in actual use. Utility Model Content

[0027] Reference Figure 1-6 A deep-channel high-flow-rate plate heat exchanger includes a connection box 1, which is set to have a top opening, a top plate 5 is fixedly installed on the top of the connection box 1, four pipes 2 are connected to the side wall of the connection box 1, a limiting rod 101 is fixedly installed inside the connection box 1, heat exchange plates 6 are evenly arranged inside the connection box 1, and the heat exchange plates 6 are stuck between the limiting rods 101. A first pushing mechanism and a second pushing mechanism are respectively arranged near both ends of the connection box 1, and a pushing frame 7 is arranged inside the connection box 1. The top plate 5 is set as a hollow structure, a high-pressure pump 4 is fixedly installed on the top of the top plate 5, the water outlet of the high-pressure pump 4 is connected with a water pipe 3, the water pipe 3 is connected with the top plate 5, and high-pressure nozzles are evenly arranged on the bottom of the top plate 5. In normal use of the plate heat exchanger, the heat exchange plate 6 is installed on the limiting rod 101, the limiting rod 101 is distributed up and down, and the upper and lower ends of the heat exchange plate 6 are provided with grooves that match the size of the limiting rod 101, so that the heat exchange plate 6 can be stuck between the limiting rods 101, The second pushing mechanism is used to squeeze the heat exchange plate 6 against the side wall of the connecting box 1, so that the hole of the heat exchange plate 6 is connected with the pipe 2 on the side wall of the connecting box 1, so that it can be used normally. When the heat exchange plate 6 needs to be cleaned, the first pushing mechanism is first used to move the heat exchange plate 6 toward the direction of the second pushing mechanism. After moving, the pushing frame 7 can be slid inward so that the pushing frame 7 can push the heat exchange plate 6. The pushing frame 7 is used to separate each heat exchange plate 6 evenly, leaving a little gap between the heat exchange plates 6. Finally, clean water is transported to the top plate 5 by the high-pressure pump 4, and is sprayed out by the high-pressure nozzle at the bottom of the top plate 5, so as to be sprayed on the water flow channel of the heat exchange plate 6, thereby playing a flushing role, and the cleaning function of the heat exchange plate 6 can be realized. After cleaning, the second pushing mechanism is used to push the heat exchange plate 6 to the position of the first pushing mechanism again, and the heat exchange plate 6 and the inner wall of the connecting box 1 are pressed against each other, so that the heat exchange plates 6 are also pressed against each other, so that they can be used normally.

[0028] Furthermore, the first pushing mechanism includes a first threaded sleeve 8, which rotates and passes through the side wall of the connecting box 1. The first threaded sleeve 8 is provided with a first screw 9 at the threaded insertion of the internal port of the connecting box 1. The first screw 9 is fixedly installed with a first push plate 10 at one end away from the first threaded sleeve 8. Two sliding rods 15 are fixedly installed on the side wall of the first push plate 10. Both sliding rods 15 slide and pass through the connecting box 1. The inner wall of the connecting box 1 is provided with a groove that matches the size of the first push plate 10, so that the first push plate 10 can be accommodated in the groove to avoid the situation where the heat exchange plate 6 is blocked by the first push plate 10 and cannot be connected with the pipeline 2. When the first pushing mechanism is in use, the first threaded sleeve 8 is manually rotated, and the first threaded sleeve 8 drives the first screw 9 and the first push plate 10 to move horizontally under the restriction of the sliding rod 15, so that it is convenient to use the first push plate 10 to push the heat exchange plate 6 to move on the limiting rod 101.

[0029] Furthermore, the second pushing mechanism includes a second push plate 11, which is slidably connected to the two limiting rods 101, and a second screw 12 is fixedly installed on the side wall of the second push plate 11. A second threaded sleeve 13 is rotatably passed through the side wall of the connecting box 1, and the second screw 12 and the second threaded sleeve 13 are threadedly connected. When the second pushing mechanism is in use, the second threaded sleeve 13 is manually rotated, and the second threaded sleeve 13 drives the second screw 12 and the second push plate 11 to move horizontally under the restriction of the limiting rods 101, thereby facilitating the use of the second push plate 11 to push the heat exchange plate 6 to move on the limiting rods 101.

[0030] Furthermore, the pushing frame 7 includes a push rod 71 and a push frame 72. The push rod 71 is set to a "U"-shaped structure. There are two push frames 72, and the two push frames 72 are fixedly installed at both ends of the push rod 71. The two arms of the push rod 71 slide through the connection box 1.

[0031] Furthermore, both sides of the heat exchange plate 6 are provided with extension pieces 61, and the length of the extension piece 61 of each heat exchange plate 6 is uniformly increased, and two push racks 72 are respectively located on both sides of the heat exchange plate 6, and the sides of the two push racks 72 close to each other are provided with teeth, and the size of the teeth decreases successively and is adapted to the size of the extension piece 61. When the heat exchange plates 6 need to be separated from each other, the push rack 7 can be manually pushed, and the push rack 7 uses the teeth on the surface that increase successively to contact the extension piece 61 of each heat exchange plate 6, wherein the longest tooth abuts against the shortest extension piece 61, and the remaining The teeth and the extension piece 61 abut against each other in turn, so that each extension piece 61 and the heat exchange plate 6 can be pushed, but the spacing of the teeth is fixed. Therefore, after pushing the heat exchange plate 6, a gap the same as the teeth can be left between adjacent heat exchange plates 6, thereby facilitating high-pressure water flushing. When the flushing is completed, since the teeth are away from the extension piece 61 abutting against it, the pushing frame 7 can move unimpeded, and the pushing frame 7 is pulled back so that it will not block the heat exchange plate 6. Finally, the cleaned heat exchange plate 6 can be pushed to the position of the pipeline 2 again using the second pushing mechanism.

[0032] Furthermore, a collecting box 14 is slidably inserted into the side wall of the connection box 1 near the bottom. By providing the collecting box 14, it is convenient to collect and clean the scale impurities flushed down.

[0033] In summary, in normal use of the plate heat exchanger, the heat exchange plate 6 is installed on the limiting rod 101, the limiting rod 101 is distributed up and down, and the upper and lower ends of the heat exchange plate 6 are provided with grooves that match the size of the limiting rod 101, so that the heat exchange plate 6 can be stuck between the limiting rods 101, and the heat exchange plate 6 is squeezed against the side wall of the connecting box 1 by the second pushing mechanism, so that the hole of the heat exchange plate 6 is connected with the pipe 2 on the side wall of the connecting box 1, so that it can be used normally. When the heat exchange plate 6 needs to be cleaned, the first pushing mechanism is first used to move the heat exchange plate 6 toward the direction of the second pushing mechanism. After the movement, the pushing frame 7 can be slid inward so that the pushing frame 7 can push the heat exchange plate 6. Use the pushing frame 7 to evenly separate each heat exchange plate 6, leaving a little gap between the heat exchange plates 6, and finally use the high-pressure pump 4 to transport clean water to the top plate 5, and use the high-pressure nozzle at the bottom of the top plate 5 to spray it out, so as to spray it on the water flow channel of the heat exchange plate 6, thereby playing a flushing role, and the cleaning function of the heat exchange plate 6 can be realized. After the cleaning is completed, the second pushing mechanism is used to push the heat exchange plate 6 to the position of the first pushing mechanism again, and the heat exchange plate 6 and the inner wall of the connecting box 1 are pressed against each other, so that the heat exchange plates 6 are also pressed against each other, so that they can be used normally. When the first pushing mechanism is in use, the first threaded sleeve 8 is manually rotated, and the first threaded sleeve 8 drives the first screw 9 and the first The push plate 10 moves horizontally under the restriction of the slide rod 15, so that the first push plate 10 is used to push the heat exchange plate 6 to move on the restriction rod 101. When the second pushing mechanism is in use, the second threaded sleeve 13 is manually rotated, and the second threaded sleeve 13 drives the second screw 12 and the second push plate 11 to move horizontally under the restriction of the restriction rod 101, so that the second push plate 11 is used to push the heat exchange plate 6 to move on the restriction rod 101. When the heat exchange plates 6 need to be separated from each other, the push frame 7 can be manually pushed. The push frame 7 uses the teeth with increasing teeth on the surface to contact the extension piece 61 of each heat exchange plate 6 respectively, and the longest teeth and the shortest extension piece 61 abut against each other. Then, the remaining teeth and extension pieces 61 abut against each other in turn, so that each extension piece 61 and the heat exchange plate 6 can be pushed, but the spacing of the teeth is fixed. Therefore, after pushing the heat exchange plate 6, a gap the same as the teeth can be left between adjacent heat exchange plates 6, thereby facilitating high-pressure water flushing. When the flushing is completed, since the teeth are away from the extension piece 61 abutting therewith, the pushing frame 7 can move unimpeded, and the pushing frame 7 is pulled back so that it does not block the heat exchange plate 6. Finally, the cleaned heat exchange plate 6 can be pushed to the position of the pipe 2 again by the second pushing mechanism. By setting the collection box 14, it is convenient to collect and clean the flushed scale impurities.
