Description

Technical Field

[0001] The invention relates to the field of heat exchangers, and in particular to a high-pressure wide-channel heat exchanger that is easy to maintain. Background Art

[0002] A plate heat exchanger is generally composed of a number of stacked metal plates with a certain corrugated shape. A thin rectangular channel is formed between the metal plates, and the heat of the heat exchange medium is exchanged through the plates. High-pressure, wide-channel plate heat exchangers are widely used in industry due to their extremely high heat exchange efficiency. However, during the heat exchange process, when the heat exchange medium passes through two plates, impurities are easily accumulated and remain between the two plates, which is not easy to clean. Existing heat exchange equipment cannot clean the impurities on the plates during the heat exchange process. Usually, all plates need to be removed for cleaning and maintenance, which is time-consuming and labor-intensive. Summary of the invention

[0003] In order to overcome the disadvantages that impurities are easily accumulated between two plates and are difficult to clean, and all plates usually need to be removed for cleaning and maintenance, which is time-consuming and labor-intensive, the present invention provides a high-pressure wide-channel heat exchanger that is easy to maintain.

[0004] The technical solution of the present invention is: a high-pressure wide-channel heat exchanger that is easy to maintain, comprising a frame; also comprising a mounting plate, a plate, an air bag, an electric push rod I, a rectangular plate, a connecting frame, an electric push rod II, a connecting plate and bristles; the frame is connected to the mounting plate; the mounting plate is slidably connected to a plurality of plates, and the plates are arranged in a horizontal trapezoidal shape; each plate has two hot fluid holes; each plate has two cold fluid holes; each plate is connected to an air bag, and the air bag is made of high-temperature resistant material; each air bag is provided with an air delivery port; each air bag is provided with a plurality of cleaning holes; the mounting plate is fixedly connected to the electric push rod I; the telescopic end of the electric push rod I is fixedly connected to the rectangular plate, and the rectangular plate is slidably connected to the mounting plate; the mounting plate is fixedly connected to the connecting frame; the connecting frame is fixedly connected to the electric push rod II; the telescopic end of the electric push rod II is fixedly connected to the connecting plate; the connecting plate is fixedly connected to a plurality of bristles, and the position and quantity of the bristles correspond to the cleaning holes, and the ends of the bristles are arranged in a scattered state.

[0005] Furthermore, the airbag and the plate are detachably connected.

[0006] Furthermore, the cleaning hole is arranged in a prism shape.

[0007] Furthermore, it also includes a sealing strip; each plate is provided with an annular groove; the airbag is fixedly connected with the sealing strip, and the sealing strip is embedded in the annular groove.

[0008] Furthermore, the sealing strip is made of heat-resistant rubber material.

[0009] Furthermore, it also includes a rubber strip; each airbag is fixedly connected to a rubber strip, and the rubber strip is also fixedly connected to the corresponding plate.

[0010] Furthermore, the airbag is filled with inert gas.

[0011] Furthermore, it also includes a limiting bucket; a plurality of limiting buckets are fixedly connected to the connecting frame, and the bristles pass through the limiting buckets, and the positions and numbers of the limiting buckets correspond to the cleaning holes.

[0012] Furthermore, it also includes a limiting block; the mounting plate is fixedly connected with a plurality of limiting blocks.

[0013] Furthermore, it also includes a guide rail and a moving block; each connecting frame is fixedly connected to a guide rail; each guide rail is slidably connected to a moving block, and the moving block is fixedly connected to the electric push rod II.

[0014] The beneficial effect is as follows: the present invention controls the electric push rod II to make the connecting plate drive the bristles to move downward in the vertical direction. After the bristles pass through the opened cleaning hole and enter between the two plates, the ends of the bristles are in the shape of a spread broom. The electric push rod II is controlled to make the corresponding connecting plate drive the bristles to move back and forth, and then the bristles clean the impurities and dirt attached to the two plates. The cleaned impurities and dirt are carried out of the plates together with the heat exchange fluid that continuously flows between the two adjacent plates, and then the impurities on the plates are cleaned during the heat exchange process, avoiding the need to shut down or stop the heat exchange for cleaning.

[0015] The present invention uses a rubber strip between the airbag and the plate to fill the gap between the airbag and the rectangular plate after the airbag is deployed, thereby preventing cleaned impurities from falling into the gap. In addition, since the airbag is filled with inert gas, the heat exchange fluid between the two plates is insulated from the outside world, thereby preventing the hot air from the outside from affecting the heat exchange efficiency of the heat exchange fluid.

[0016] The present invention limits the movement of the rectangular plate by means of a limit block, and then squeezes the plate when the rectangular plate moves, so that when the plates are close to each other, the rectangular plate is limited after contacting the limit block, thereby preventing the spacing between the plates from being too small, resulting in impurities easily clogging the heat exchange fluid when it passes between the two plates, thereby reducing the heat exchange efficiency.

[0030] The frame includes a fixed seat 1, a fixed rod 2, a fixed plate 4, a hot fluid pipe 5 and a cold fluid pipe 6; each of the two fixed seats 1 is fixedly connected to a fixed rod 2; one of the fixed rods 2 is fixedly connected to a fixed plate 4, and the fixed plate 4 is fixedly connected to a mounting plate 101, and the fixed plate 4 is fixedly connected to a connecting frame 106; the other fixed rod 2 is fixedly connected to the mounting plate 101; the fixed plate 4 is fixedly connected to a hot fluid pipe 5, and the hot fluid pipe 5 corresponds to the hot fluid hole 1021 on the plate 102; the fixed plate 4 is fixedly connected to a cold fluid pipe 6, and the cold fluid pipe 6 corresponds to the cold fluid hole 1022 on the plate 102; the rectangular plate 105 is fixedly connected to another hot fluid pipe 5 and another cold fluid pipe 6, and the hot fluid pipe 5 and the cold fluid pipe 6 fixed to the rectangular plate 105 also correspond to the hot fluid hole 1021 and the cold fluid hole 1022 on the plate 102, respectively.

[0031] The airbag 103 and the plate 102 are detachably connected, so that the airbag 103 can be quickly replaced and maintained.

[0032] The cleaning hole 1032 is arranged in a prism shape.

[0033] It also includes a sealing strip 1010 ; each plate 102 is provided with an annular groove 1023 ; the airbag 103 is fixedly connected with the sealing strip 1010 , and the sealing strip 1010 is embedded in the annular groove 1023 .

[0034] The sealing strip 1010 is made of heat-resistant rubber material to prevent the high-temperature heat exchange material from affecting the sealing performance of the sealing strip 1010 during the heat exchange process.

[0035] It also includes a rubber strip 1011 ; each airbag 103 is fixedly connected to a rubber strip 1011 , and the rubber strip 1011 is also fixedly connected to the corresponding plate 102 .

[0036] The air bag 103 is filled with an inert gas.

[0037] When in use, first connect the external feed pipe to the hot fluid pipe 5 and the cold fluid pipe 6 on the fixed plate 4 respectively, connect the external discharge pipe to the hot fluid pipe 5 and the cold fluid pipe 6 on the rectangular plate 105, connect the external air pump to the air delivery port 1031, and connect the external water pump to the connecting plate 108. Then, control the external feed pipe to transport the hot fluid to the hot fluid pipe 5, and the hot fluid enters the gap between the left side of the first plate 102 and the fixed plate 4 from the hot fluid pipe 5 through the hot fluid hole 1021. At the same time, control the external feed pipe to transport the cold fluid to the cold fluid pipe 6, and the cold fluid enters the cold fluid hole 1022. In the gap between the right side of the first plate 102 and the left side of the second plate 102, the hot fluid and the cold fluid exchange heat on the first plate 102. Subsequently, the hot fluid continues to pass through the hot fluid hole 1021 of the second plate 102 and passes through the subsequent plate 102, while the cold fluid continues to pass through the cold fluid hole 1022 of the second plate 102 and passes through the subsequent plate 102, thereby utilizing the cold fluid to cool down the hot fluid for heat exchange. Finally, the cooled hot fluid flows out from the hot fluid pipe 5 on the rectangular plate 105, while the cold fluid after heat exchange flows out from the cold fluid pipe 6 on the rectangular plate 105, thereby completing the heat exchange.

[0038] During normal heat exchange, the external air pump is controlled to start, and air is supplied to the airbag 103 through the air supply port 1031, so that the airbag 103 expands. Subsequently, the electric push rod Ⅰ104 is controlled to drive the rectangular plate 105 to slide to the left on the mounting plate 101, and then the rectangular plate 105 squeezes a plurality of plates 102, so that the airbag 103 between two adjacent plates 102 is squeezed, so that the cleaning hole 1032 is squeezed and closed, thereby ensuring the sealing between the two adjacent plates 102. During normal heat exchange, due to The spacing between the plates 102 is 25-30 mm. Therefore, when the heat exchange material flows between two adjacent plates 102, it is limited by the spacing between the two adjacent plates 102. When the heat exchange material enters between the two plates 102, since the heat exchange material has a certain flow rate, the heat exchange material is easy to fill the gap between the two adjacent plates 102, and then it is easy to overflow from the cleaning hole 1032. Therefore, it is necessary to make the plate 102 squeeze the airbag 103 and then seal the cleaning hole 1032.

[0039] When the plate 102 needs to be cleaned, the heat exchange process continues, and the hot fluid and the cold fluid continue to flow between the plates 102. At the same time, the electric push rod Ⅰ104 is controlled to drive the rectangular plate 105 to slide to the right on the mounting plate 101, and then the rectangular plate 105 pulls the plate 102 to slide to the right, so that the distance between the plates 102 increases, thereby reducing the squeezing of the airbag 103 by the plate 102, and the airbag 103 recovers its deformation and unfolds, so that the cleaning hole 1032 reopens. At this time, the distance between the two plates 102 increases. The distance between the two plates 102 is increased to 2-3 cm, so that the heat exchange material between the two adjacent plates 102 will not flow through the high superheated fluid hole 1021, that is, after the distance between the two plates 102 is increased, the heat exchange material has enough space to flow, and the heat exchange fluid will not overflow from the cleaning hole 1032. Then, the electric push rod II 107 is controlled to make the connecting plate 108 drive the bristles 109 to move downward in the vertical direction. After the bristles 109 pass through the opened cleaning hole 1032 and enter between the two plates 102, the ends of the bristles 109 are in the shape of a spread broom, such as Figure 6 As shown, by controlling the electric push rod II 107, the corresponding connecting plate 108 drives the bristles 109 to move back and forth, and then the bristles 109 clean the impurities and dirt attached to the two plates 102. Since the plates 102 are arranged in a trapezoidal shape, the scattered bristles 109 are convenient for cleaning various areas within the plate 102, avoiding the generation of cleaning dead corners. The cleaned impurities and dirt are carried out of the plate 102 together with the heat exchange fluid that continuously flows between the two adjacent plates 102, and then the impurities on the plate 102 are cleaned during the heat exchange process, avoiding the need to shut down or stop the heat exchange for cleaning.

[0040] Since the cleaning hole 1032 is prismatic, when the airbag 103 is squeezed and closed, the inner walls of the cleaning hole 1032 fit tightly together, which reduces the gap after the cleaning hole 1032 is squeezed compared to the usually circular cleaning hole 1032, thereby improving the sealing effect.

[0041] Initially, the sealing strip 1010 is embedded in the annular groove 1023, and during normal heat exchange, the airbag 103 is squeezed to tightly squeeze the sealing strip 1010 into the annular groove 1023 on the plate 102, thereby improving the sealing effect and preventing the heat exchange fluid from seeping out from between the two plates 102. When the electric push rod Ⅰ104 causes the rectangular plate 105 to pull the two adjacent plates 102 away from each other, the airbag 103 is unfolded and does not squeeze the sealing strip 1010, but the sealing strip 1010 is still embedded in the annular groove 1023 and does not detach, so that during the cleaning process of the plate 102, the heat exchange fluid can also be prevented from seeping out from between the two plates 102.

[0042] When the cleaned impurities fall from the plate 102, there will be a gap between the cylindrical airbag 103 and the rectangular plate 102 after the airbag 103 is deployed, and then impurities and dirt will fall into the gap. They are not easily carried away by the flowing heat exchange fluid, which reduces the cleaning effect. Therefore, the rubber strip 1011 between the airbag 103 and the plate 102 is used to fill the gap between the airbag 103 and the rectangular plate 102 after the airbag 103 is deployed to prevent the cleaned impurities from falling into the gap.

[0043] Since the airbag 103 is filled with inert gas, the heat exchange fluid between the two plates 102 is insulated from the outside, thereby preventing the hot air from the outside from affecting the heat exchange efficiency of the heat exchange fluid.

[0044] It should be noted that the definition of cold fluid and hot fluid for heat exchange is not limited to a certain substance. Cold fluid and hot fluid can be liquid and gaseous substances with heating and cooling requirements, such as sewage, clear juice, waste honey, waste gas and air.

[0045] Example 2

[0046] On the basis of Example 1, Figure 2 and Figure 4-Figure 7 As shown, it also includes a limiting bucket 201; a plurality of limiting buckets 201 are fixedly connected to the connecting frame 106, and the bristles 109 pass through the limiting buckets 201, and the positions and numbers of the limiting buckets 201 correspond to the cleaning holes 1032.

[0047] It also includes a limiting block 202 ; the mounting plate 101 is fixedly connected to two limiting blocks 202 .

[0048] In Example 1, when the bristles 109 are poked into the cleaning hole 1032, in order to ensure the cleaning effect of the plate 102 after the bristles 109 enter between the two plates 102, the bristles 109 corresponding to each cleaning hole 1032 are in a scattered state. Therefore, it is not easy for all the scattered bristles 109 to enter the cleaning hole 1032. At this time, the scattered bristles 109 are guided and limited by the limiting bucket 201, so that all the bristles 109 can enter the cleaning hole 1032, thereby improving the cleaning efficiency. During normal heat exchange, the rectangular plate 105 is limited when it moves by the limiting block 202, and then the rectangular plate 105 moves to squeeze the plate 102, so that the plates 102 are close to each other. The rectangular plate 105 is limited after contacting the limiting block 202, thereby avoiding the spacing between the plates 102 being too small, resulting in impurities easily clogging the heat exchange fluid when passing between the two plates 102, thereby reducing the heat exchange efficiency.

[0049] Example 3

[0050] On the basis of Example 2, Figure 1-Figure 4As shown, it also includes a guide rail 203 and a moving block 204; each connecting frame 106 is bolted to a guide rail 203; each guide rail 203 is slidably connected to a moving block 204, and the moving block 204 is bolted to the electric push rod II 107.

[0051] Since the surface of the plate heat exchanger used in industry will be adhered to a lot of dust, which affects the heat exchange efficiency of the heat exchanger, therefore, during normal heat exchange, the guide rail 203 is controlled to make the moving block 204 drive the electric push rod II 107, the connecting plate 108 and the bristles 109 to move left and right, and the electric push rod II 107 drives the connecting plate 108 and the bristles 109 to move up and down, and then the bristles 109 clean the dust adhered to the plate 102 and the airbag 103, thereby improving the heat exchange efficiency and reducing manual maintenance.

[0052] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
