Description

Technical Field

[0001] This utility model relates to the field of plate heat exchanger technology, and in particular to a fixing device for plate heat exchangers. Background Technology

[0002] Plate heat exchangers are widely used in industrial production and daily life. They are made up of a series of metal plates with a certain corrugated shape stacked together to achieve efficient heat exchange. The fixing device of the plate heat exchanger is used to securely install the heat exchanger plates and ensure its normal operation.

[0003] However, existing plate heat exchanger fixing devices have many shortcomings. First, the fixing method is not flexible and stable enough, making it difficult to adapt to plate heat exchangers of different specifications and sizes. They are prone to loosening during use, affecting the normal operation and heat exchange efficiency of the heat exchanger. Second, key parts of the fixing device, such as the contact points between the clamps and the plates, are prone to accumulating dirt and impurities. These dirt and impurities not only affect the fixing effect of the device, causing the plates to loosen and thus affecting the overall stability of the heat exchanger, but may also hinder heat transfer and reduce the heat exchanger's heat exchange performance. Usually, manual disassembly of the heat exchanger is required for cleaning, which is not only time-consuming and labor-intensive, but may also damage the heat exchanger during disassembly and installation. To solve the above problems, we propose a fixing device for plate heat exchangers. Utility Model Content

[0014] 1. This type of fixing device for plate heat exchangers can effectively absorb and disperse vibration energy through multiple sets of buffer components, reducing the impact of vibration on the heat exchanger and the fixing device.

Then, a second motor is started, driving the water delivery rod to rotate. The cleaning brushes on the outer wall of the water delivery rod rotate accordingly. Simultaneously, water from the water tank is delivered to the water delivery rod through a water pipe and sprayed out from the spray nozzles to rinse the plates of the plate heat exchanger. The rotating cleaning brushes scrub the plate surface, removing dirt. At the same time, a first motor is started, driving a first drive shaft to rotate. The first gear on the first drive shaft meshes with the second gear on the second drive shaft, thereby... The second drive shaft rotates, causing the rotating block and guide plate to rotate. Based on the size of the plate heat exchanger and cleaning requirements, the positions of the guide plate and water delivery rod are changed through the cooperation of the first motor and the third electric telescopic rod.

A first electric slider 22 is slidably connected to the inner side of the first electric sliding groove 21. A fixing frame 23 is provided at one end of each set of first electric sliders 22. A third slot 25 is provided at one end of each set of fixing frames 23. Multiple sets of first electric telescopic rods 24 are provided at the other end of each set of fixing frames 23. A first clamping plate 26 is provided through the fixing frame 23 at the output end of each first electric telescopic rod 24. The first clamping plate 26 fits into the third slot 25.

Guide plates 37 are provided at the telescopic ends of each set of third electric telescopic rods 36.

[0025] In this embodiment, a second motor 38 is provided at the front end of each of the multiple sets of guide plates 37, and a water supply rod 39 is provided at the output end of each of the multiple sets of second motors 38. A water supply pipe 394 is provided at the other end of the water supply rod 39. The outer side wall of the water supply rod 39 is rotatably connected to the inner side wall of the multiple sets of guide plates 37. A cleaning brush 392 is arranged in a circular array on the outer side wall of the water supply rod 39. A multiple set of spray holes 391 is arranged in a circular array on the outer side wall of the water supply rod 39. The multiple sets of spray holes 391 are connected to the interior of the water supply rod 39. A sixth slot 393 is opened at one end of each of the multiple sets of first clamping plates 26. The sixth slot 393 fits into the water supply rod 39.

[0026] Specifically, the third electric telescopic rod 36 is activated, and the telescopic end of the third electric telescopic rod 36 pushes the water delivery rod 39 out of the sixth slot 393 and brings the water delivery rod 39 close to the plate. Multiple sets of cleaning brushes 392 come into contact with the surface of the plate. Then, the second motor 38 is activated, and the second motor 38 drives the water delivery rod 39 to rotate. The cleaning brushes 392 on the outer wall of the water delivery rod 39 rotate accordingly.

[0027] In this embodiment, a first motor 3 is provided at the front end of each of the multiple sets of first clamping plates 26, a first transmission shaft 31 is provided at the output end of the first motor 3, a first gear 32 is provided on the outer side wall of the first transmission shaft 31, and a second gear 33 is provided on the front side of the outer side wall of the front set of second transmission shafts 34, and the first gear 32 and the second gear 33 mesh with each other.

[0028] Specifically, the first motor 3 is started, which drives the first transmission shaft 31 to rotate. The first gear 32 on the first transmission shaft 31 meshes with the second gear 33 on the second transmission shaft 34, thereby driving the second transmission shaft 34 to rotate. The rotation of the second transmission shaft 34 causes the rotating block 35 and the guide plate 37 to rotate.

[0029] In this embodiment, the upper and lower ends of the multiple sets of first clamping plates 26 are provided with fourth slots 27, the front and rear side walls of the multiple sets of fourth slots 27 are provided with second electric slots 28, the inner sides of the multiple sets of second electric slots 28 are slidably connected with second electric sliders 29, and the corresponding end of the multiple sets of second electric sliders 29 is provided with a fixing plate 291. The fixing plate 291 fits into the fourth slots 27, and the second electric slider 29 is located below the side wall of the fixing plate 291.

[0030] Specifically, the second electric slider 29 is activated, causing it to slide within the second electric slot 28, thereby moving multiple sets of fixed plates 291 in the up and down directions respectively.

[0031] In this embodiment, a fifth slot 292 is provided at the front end of the fixing plate 291, and a plurality of second electric telescopic rods 293 are provided at one end of the inner side of the fixing plate 291. A second clamping plate 294 is provided at the output end of the plurality of second electric telescopic rods 293, and the second clamping plate 294 fits into the fifth slot 292.

[0032] Specifically, when the fixed plate 291 reaches the appropriate position, the second electric telescopic rod 293 is activated. The output end of the second electric telescopic rod 293 pushes the second clamping plate 294 to move towards the plate, so that the second clamping plate 294 clamps the plate heat exchanger.

[0033] In this embodiment, a water tank 395 is provided at the rear end of the support frame 2, and the other ends of multiple sets of water supply pipes 394 are fixedly connected to the front end of the water tank 395. A first slot 11 is provided at the top of the bottom plate 1, and multiple sets of buffer components 15 are provided at the bottom inner side of the bottom plate 1. A buffer plate 16 is provided at the top of the multiple sets of buffer components 15, and multiple sets of water-permeable holes 17 are provided at the top of the buffer plate 16.

[0034] Specifically, the water in the water tank 395 is transported to the water supply rod 39 through the water supply pipe 394. The multiple sets of buffer components 15 can effectively absorb and disperse vibration energy, reducing the impact of vibration on the heat exchanger and the fixed device.

[0035] In this embodiment, a second slot 18 is provided in the middle of the bottom of the inner side of the base plate 1, and a waste liquid collection box 13 is provided at the bottom of the base plate 1. The first slot 11 is connected to the inside of the waste liquid collection box 13 through the second slot 18. A drawer 12 is detachably connected to the front end of the waste liquid collection box 13, and a base 14 is provided at each of the four corners of the bottom of the waste liquid collection box 13.

[0036] Specifically, the waste liquid generated during the cleaning process flows into the first slot 11 of the base plate 1 through multiple sets of water-permeable holes 17 on the buffer plate 16, and then flows into the waste liquid collection tank 13 through the second slot 18. The waste liquid is automatically collected by gravity. Finally, the waste liquid is easily cleaned through the drawer 12. After cleaning, the drawer 12 is reinstalled back into the waste liquid collection tank 13 so that waste liquid can be collected again next time.

[0037] It should be noted that this utility model is a fixing device for plate heat exchangers. The user moves the plate heat exchanger above the buffer plate 16. Multiple sets of buffer components 15 effectively absorb and disperse vibration energy, reducing the impact of vibration on the heat exchanger and the fixing device. After placing the plate heat exchanger between the fixing frames 23, the first electric slider 22 is activated, causing it to slide within the first electric sliding groove 21. The height of the fixing frame 23 is precisely adjusted according to the actual height of the plate heat exchanger. The first electric telescopic rod 24 is then activated, and its output end pushes the first clamping plate 26 closer to the heat exchanger plates until it makes tight contact with the plates, thus clamping the plate heat exchanger. This device is suitable for plate heat exchangers of different specifications and sizes. When the plate heat exchanger is in use for a period of time... Over time, dirt and impurities can easily accumulate at the contact point between the first clamping plate 26 and the plate. At this point, the second electric slider 29 is activated, causing it to slide within the second electric slot 28. This drives multiple sets of fixing plates 291 to move up and down respectively. When the fixing plates 291 reach the appropriate position, the second electric telescopic rod 293 is activated. The output end of the second electric telescopic rod 293 pushes the second clamping plate 294 towards the plate, causing the second clamping plate 294 to clamp the plate heat exchanger. At the same time, the output end of the first electric telescopic rod 24 pulls the first clamping plate 26 away from the heat exchanger plate, thereby releasing the clamping of the plate by the first clamping plate 26. With the cooperation of the second electric telescopic rod 293 and the first electric telescopic rod 24, the plate is always kept in a clamped and fixed state.

[0038] When the first clamping plate 26 moves away from one end of the heat exchanger plate, the third electric telescopic rod 36 is activated. The telescopic end of the third electric telescopic rod 36 pushes the water delivery rod 39 out of the sixth slot 393, bringing the water delivery rod 39 closer to the plate. Multiple sets of cleaning brushes 392 then contact the plate surface. Subsequently, the second motor 38 is activated, driving the water delivery rod 39 to rotate. The cleaning brushes 392 on the outer wall of the water delivery rod 39 rotate accordingly. Simultaneously, water in the water tank 395 is delivered to the water delivery rod 39 through the water pipe 394. The cleaning fluid sprays from the nozzle 391 to rinse the plates of the plate heat exchanger. A rotating cleaning brush 392 scrubs the plate surface, removing dirt. Simultaneously, the first motor 3 is activated, driving the first drive shaft 31 to rotate. The first gear 32 on the first drive shaft 31 meshes with the second gear 33 on the second drive shaft 34, thus driving the second drive shaft 34 to rotate. The rotation of the second drive shaft 34 causes the rotating block 35 and guide plate 37 to rotate. Depending on the size of the plate heat exchanger and cleaning requirements, the first motor... With the cooperation of the first motor 3 and the third electric telescopic rod 36, the positions of the guide plate 37 and the water delivery rod 39 are changed, allowing the water delivery rod 39 and multiple sets of cleaning brushes 392 to clean the contact area between the first clamping plate 26 and the plate. After the contact surface at the plate is cleaned, the third electric telescopic rod 36 retracts, bringing the water delivery rod 39 closer to the first clamping plate 26, and the multiple sets of cleaning brushes 392 come into contact with the surface of the first clamping plate 26. With the cooperation of the first motor 3 and the third electric telescopic rod 36, the positions of the guide plate 37 and the water delivery rod 39 are changed. The position of the rod 39 allows the water delivery rod 39 and multiple sets of cleaning brushes 392 to clean the contact surface of the first clamping plate 26, thus achieving the cleaning function. The waste liquid generated during the cleaning process flows into the first slot 11 of the bottom plate 1 through multiple sets of water-permeable holes 17 on the buffer plate 16, and then flows into the waste liquid collection tank 13 through the second slot 18. The waste liquid is automatically collected by gravity. Finally, the waste liquid is easily cleaned through the drawer 12. After cleaning, the drawer 12 is reinstalled back into the waste liquid collection tank 13 so that waste liquid can be collected again next time.
