Description

Technical Field

[0001] This utility model relates to an anti-scaling plate evaporator, belonging to the technical field of plate evaporators. Background Technology

[0002] Plate evaporators, as a highly efficient and compact heat exchange device, are widely used in chemical, food, pharmaceutical and new energy fields.

[0003] After long-term use, scale layer is easily formed on the surface of the heat exchange plates of plate evaporators, which leads to a decrease in heat transfer efficiency and an increase in energy consumption. In the existing technology, the scale layer of plate evaporators is mainly removed by disassembling the heat exchange plates and then using high-pressure water jet or mechanical brushing. This method requires disassembling the equipment, which is time-consuming and labor-intensive, thus reducing the practicality of plate evaporators.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an anti-scaling plate evaporator, which solves the problem that in the prior art, the scaling of plate evaporators is mainly cleaned by disassembling the heat exchange plates and then using high-pressure water jet or mechanical brushing to remove the scale layer. This method requires a complete shutdown and disassembly of the equipment, which is time-consuming and labor-intensive, thus reducing the practicality of the plate evaporator.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution: A scale-resistant plate evaporator includes a mounting frame, on which a fixed clamping plate and a vertical block are fixedly mounted. Two crossbars are fixedly mounted between the fixed clamping plate and the vertical block. A movable clamping plate is slidably connected to the two crossbars. Multiple heat exchange plates are arranged between the fixed clamping plate and the movable clamping plate, and the heat exchange plates are slidably connected between the crossbars. A stabilizing column is fixedly mounted on the side of the fixed clamping plate near the movable clamping plate. A disassembly frame is provided on the stabilizing column. An installation groove is opened through the disassembly frame and is slidably connected to the stabilizing column. Two positioning shafts are rotatably connected to the disassembly frame. A connecting pipe is fixedly connected to the positioning shaft. A nozzle communicating with the inside of the connecting pipe is fixedly connected to the connecting pipe. A cleaning mechanism is provided on the disassembly frame for cleaning scale on the heat exchange plates. A water storage tank is provided on the mounting frame. A flushing mechanism is provided on the water storage tank for flushing the heat exchange plates without disassembling them.

[0007] By adopting the above technical solution, when in use, the water storage tank is filled with cleaning agent solution. The output end of the flushing mechanism is connected to the water inlet or outlet on the fixed pressure plate. Then, the flushing mechanism is started, and the flushing mechanism injects the cleaning agent solution from the water storage tank between the heat exchange plates, thereby dissolving the scale inside the heat exchange plates. The dissolved water is then discharged. This cleaning method does not require disassembling the heat exchange plates and avoids the occurrence of a large amount of scale on the heat exchange plates. Before using the cleaning mechanism, the movable clamping plate needs to be disassembled and moved away from the fixed clamping plate. Then, push the heat exchange plates to slide back and forth along the extension trajectory of the crossbar, thereby creating a gap between the heat exchange plates. In the initial state, the two connecting pipes are mirror images of each other and are separated from each other. At this time, the connecting pipes will not affect the movement of the disassembly frame. Push the disassembly frame along the stabilizing column and push it between the two heat exchange plates. Then, start the cleaning mechanism. The cleaning mechanism drives the two stabilizing columns to reciprocate in opposite or relative directions around the positioning axis. During this process, the nozzles drive the opposite sides of the two heat exchange plates to rinse and clean the scale on the heat exchange plates.

[0008] The present invention is further configured such that: the cleaning mechanism includes a mounting box fixedly connected to the disassembly frame, a positioning shaft passing through the mounting box, a cylinder fixedly connected to the mounting box, the output end of the cylinder passing through the mounting box and fixedly connected to two racks, the two racks being arranged in opposite directions, the racks meshing with gears, and a first fixing mechanism for positioning the disassembly frame is provided.

[0009] By adopting the above technical solution, when cleaning the scaled heat exchange plates, the starting cylinder can drive the two racks to move up and down. The racks drive the gears to rotate reciprocally. Because the two racks are arranged in opposite directions, their up-and-down movement drives the two gears to rotate in opposite directions, which in turn drives the two connecting pipes to rotate reciprocally in opposite or opposite directions. When the two connecting pipes rotate in opposite directions, the included angle between them increases. When the two connecting pipes rotate to their extreme positions, the angle between them ensures that they do not obstruct the sliding of the disassembly frame on the stabilizing column. When the two connecting pipes rotate relative to each other, the included angle between them decreases. During the reciprocating rotation of the two connecting pipes, the nozzles on the connecting pipes can rinse the heat exchange plates, and can rinse both opposite sides of the two heat exchange plates at once, making the cleaning efficiency of the heat exchange plates higher.

[0010] This utility model is further configured as follows: the first fixing mechanism includes a first bolt threadedly connected to the disassembly frame, a stabilizing column having multiple adjusting grooves, the end of the first bolt being inserted into the adjusting groove, and a second fixing mechanism for positioning the first bolt on the disassembly frame. The second fixing mechanism includes a mounting block fixedly connected to the disassembly frame, a sliding groove extending through the mounting block, a fixing block slidably connected within the sliding groove, a rotating rod rotatably connected to the side of the fixing block away from the connecting pipe, a handle block fixedly connected to the end of the rotating rod away from the fixing block, a spring fixedly connected between the handle block and the mounting block, a limiting post fixedly connected to the rotating rod, the side of the fixing block away from the rotating rod being inclined, and a positioning groove communicating with the sliding groove on the side of the mounting block away from the connecting pipe, allowing the limiting post to be inserted into the positioning groove.

[0011] By adopting the above technical solution, when the disassembly frame is installed on the stabilizing column, the stabilizing column needs to be slid into the mounting groove. During this process, the upper surface of the stabilizing column contacts the inclined surface of the fixing block and pushes the fixing block to move closer to the rotating rod, thereby driving the fixing block, rotating rod, and handle block to move synchronously. During this process, the spring is stretched, causing the spring to deform. When the stabilizing column slides to abut against the top wall of the mounting groove, the fixing block separates from the stabilizing column. Under the action of the spring's release force, the fixing block is pushed to slide closer to the stabilizing column, and the upper surface of the fixing block abuts against the lower surface of the stabilizing column, thereby restricting the disassembly frame so that it cannot move up and down or left and right, and can only slide back and forth along the direction of the stabilizing column.

[0012] When the first bolt is rotated so that its end is inserted into the appropriate adjustment groove, the first bolt and the adjustment groove cooperate to restrict the disassembly frame, preventing it from moving forward or backward and allowing it to move up and down. In turn, the first fixing mechanism and the second fixing mechanism cooperate to fix the disassembly frame, preventing it from shifting and thus ensuring the stability of the cleaning mechanism in cleaning the heat exchange plates.

[0013] During disassembly, pull out the handle block, causing it to simultaneously move the rotating rod and the fixed block away from the stabilizing column, thereby releasing the fixed block's restriction on the stabilizing column. In this process, the limiting column is also displaced out of the mounting block. Then, rotate the handle block to make the limiting column rotate, and then push the handle block to make it insert the limiting column into the positioning groove. Under the action of the spring's release force, the current state of the fixed block is positioned. At this time, the disassembly frame can be moved upward, allowing the stabilizing column to slide out of the mounting groove, thus making the cleaning mechanism flexible to disassemble and facilitating maintenance of the cleaning mechanism.

[0014] The present invention is further configured as follows: the rinsing mechanism includes a motor fixedly installed on a water storage tank, the output shaft of the motor being poweredly connected to a vertical rod penetrating into the water storage tank, multiple stirring rods being fixedly connected to the vertical rod, a water inlet fixedly connected to the water storage tank and communicating with its interior, a cover being provided on the water inlet, a water outlet pipe penetrating into its interior being fixedly connected to one side of the water storage tank, a water pump being fixedly installed inside the water storage tank, the output end of the water pump being fixedly connected to the end of the water outlet pipe penetrating into the water storage tank, a flexible hose being fixedly connected to the end of the water outlet pipe away from the water storage tank, and a flange pipe being fixedly connected to the end of the flexible hose away from the water outlet pipe.

[0015] By adopting the above technical solution, during use, the descaling agent is poured into the water storage tank through the inlet. Then, the motor is started to drive the vertical rod and stirring rod to stir the water and agent in the water storage tank, ensuring thorough mixing. The water pump is then started, and the pump transmits the agent mixture from the water storage tank to the inlet or outlet through the outlet pipe, hose, and flange pipe, allowing the agent mixture to enter between the heat exchange plates. After standing for a period of time, the agent can dissolve the scale inside the heat exchange plates, thereby preventing the formation of large amounts of scale. Cleaning the heat exchange plates does not require disassembling the entire evaporator, making the operation simple and labor-saving, thus improving the service life of the plate evaporator and enhancing its practicality.

[0016] The present invention is further configured such that: multiple clamping bolts are provided between the fixed clamping plate and the movable clamping plate; support plates are fixedly connected to the opposite sides of the water storage tank; and two limiting grooves are provided on the heat exchange plate, with the limiting grooves slidably connected to the crossbar.

[0017] By adopting the above technical solution, the distance between the fixed clamping plate and the movable clamping plate can be adjusted by adjusting the clamping bolts, so that the fixed clamping plate and the movable clamping plate can clamp the heat exchange plate located between them, so that the heat exchange plate is tightly attached to the heat exchange plate.

[0018] The present invention is further configured such that: multiple mounting frames are fixedly connected to the connecting pipe, a connecting block is slidably connected inside the mounting frame, a connecting hole is opened through one side of the connecting block, a second bolt is threadedly connected to the mounting frame, the end of the second bolt is inserted into the connecting hole, a connecting plate is fixedly connected to the side of the connecting block away from the connecting pipe, and a brush is fixedly connected to the side of the connecting plate away from the connecting block.

[0019] By adopting the above technical solution, in the initial state, the brush is not installed on the connecting pipe. When the scale on the heat exchange plate is stubborn, the brush can be installed on the connecting pipe to clean the heat exchange plate. First, slide the connecting block into the mounting frame, rotate the second bolt so that its end is inserted into the connecting hole, thereby fixing the connecting block in the mounting frame, and then fix the connecting plate and the brush to complete the installation of the brush. Push the heat exchange plate so that one side of the heat exchange plate abuts against the brush. At this time, start the cleaning mechanism, which can drive the brush to reciprocate around the center of the positioning shaft, thereby driving the brush to clean one side of the heat exchange plate and remove the scale on the heat exchange plate.

[0020] The beneficial effects of this utility model are as follows: the cleaning agent is poured into the water storage tank through the inlet, and then the motor is started to drive the vertical rod and stirring rod to stir the water and agent in the water storage tank, so that the water and agent can be fully stirred. The water pump is started, and the water pump transmits the agent mixture in the water storage tank to the inlet or outlet through the outlet pipe, hose and flange pipe, so that the agent mixture can enter between the heat exchange plates. After standing for a period of time, the agent can dissolve the scale in the heat exchange plates, thereby avoiding the formation of a large amount of scale in the heat exchange plates. Cleaning the heat exchange plates does not require disassembling the entire evaporator, the operation is simple and labor-saving, thereby improving the service life of the plate evaporator and thus improving the practicality of the plate evaporator.

[0030] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following details... Figure 1-7 As shown, this utility model is further illustrated.

[0031] like Figure 1-2 As shown, this utility model is an anti-scaling plate evaporator, including a mounting frame 3. A fixed clamping plate 1 and a vertical block 4 are fixedly mounted on the mounting frame 3 by bolts. Two horizontal bars 5 are fixedly mounted between the fixed clamping plate 1 and the vertical block 4 by bolts. A movable clamping plate 2 is slidably connected to the two horizontal bars 5. Multiple heat exchange plates 6 are arranged between the fixed clamping plate 1 and the movable clamping plate 2, and the heat exchange plates 6 are slidably connected between the horizontal bars 5. A stabilizing column 8 is fixedly mounted on the side of the fixed clamping plate 1 near the movable clamping plate 2. A disassembly frame 9 is provided on the stabilizing column 8. The disassembly frame 9 is n-shaped and has a through-hole mounting groove 23. The mounting groove 23 connects with... The stabilizing column 8 is slidably connected, and the mounting groove 23 is opened on the two vertical blocks of the disassembly frame 9. Two positioning shafts 28 are rotatably connected to the disassembly frame 9. The positioning shafts 28 are located between the two vertical plates of the disassembly frame 9. A connecting pipe 24 is fixedly connected to the positioning shaft 28. The connecting pipe 24 is located between the two vertical blocks of the disassembly frame 9. A nozzle 25 communicating with its interior is fixedly connected to the connecting pipe 24. A cleaning mechanism is provided on the disassembly frame 9. The cleaning mechanism is used to clean the scale on the heat exchange plate 6. A water storage tank 10 is provided on the mounting frame 3. A flushing mechanism is provided on the water storage tank 10. The flushing mechanism can flush the heat exchange plate 6 without disassembling the heat exchange plate 6.

[0032] In use, the water storage tank 10 is filled with cleaning solution. The output end of the flushing mechanism is connected to the inlet or outlet on the fixed clamping plate 1. Then the flushing mechanism is started, and the flushing mechanism injects the cleaning solution from the water storage tank 10 between the heat exchange plates 6, thereby dissolving the scale inside the heat exchange plates 6. The dissolved water is then discharged. This cleaning method does not require disassembling the heat exchange plates 6 and avoids the formation of a large amount of scale on the heat exchange plates 6. Before using the cleaning mechanism, the movable clamping plate 2 needs to be disassembled and moved away from the fixed clamping plate 1. Then, the heat exchange plate 6 is pushed so that it slides back and forth along the extension trajectory of the crossbar 5, thereby creating a gap between the heat exchange plates 6. In the initial state, the two connecting pipes 24 are mirror images of each other and are separated from each other. At this time, the connecting pipes 24 will not affect the movement of the disassembly frame 9. Then, the disassembly frame 9 is pushed along the stabilizing column 8 and pushed between the two heat exchange plates 6. Then, the cleaning mechanism is started. The cleaning mechanism drives the two stabilizing columns 8 to rotate back and forth in opposite directions around the positioning shaft 28. During this process, the nozzle 25 is driven to rinse the opposite sides of the two heat exchange plates 6, thereby rinsing and cleaning the scale on the heat exchange plates 6.

[0033] like Figure 5 As shown, the cleaning mechanism includes a mounting box 22 fixedly connected to the disassembly frame 9. A positioning shaft 28 passes through the mounting box 22. A cylinder 21 is fixedly connected to the mounting box 22. The output end of the cylinder 21 passes through the mounting box 22 and is fixedly connected to two racks 26. The racks 26 are fixedly connected and arranged in opposite directions. The racks 26 mesh with gears 27. A positioning tube is provided on the connecting pipe 24. The positioning tube is connected to a water source and is a flexible hose. The disassembly frame 9 is provided with a first fixing mechanism for positioning it.

[0034] When cleaning the scaled heat exchange plates 6, the starting cylinder 21 drives the two racks 26 to move up and down. The racks 26 drive the gears 27 to reciprocate. Because the two racks 26 are arranged in opposite directions, their up-and-down movement drives the two gears 27 to rotate in opposite directions, which in turn drives the two connecting pipes 24 to reciprocate in opposite or opposite directions. When the two connecting pipes 24 rotate in opposite directions, the included angle between them increases. When the two connecting pipes 24 rotate to their extreme positions, the angle between them prevents the disassembly frame 9 from sliding on the stabilizing column 8. When the two connecting pipes 24 rotate relative to each other, the included angle between them decreases. During the reciprocating rotation of the two connecting pipes 24, the nozzles 25 on the connecting pipes 24 can rinse the heat exchange plates 6, and can rinse both opposite sides of the two heat exchange plates 6 at once, making the cleaning efficiency of the heat exchange plates 6 higher.

[0035] After one side of the heat exchange plate 6 has been rinsed, the heat exchange plate 6 can be moved to the other side of the connecting pipe 24 to rinse the other side of the heat exchange plate 6, ensuring the cleaning effect of the heat exchange plate 6.

[0036] like Figure 5-6 As shown, the first fixing mechanism includes a first bolt 20 threadedly connected to the disassembly frame 9. The first bolt 20 passes through the cross block of the disassembly frame 9. The stabilizing column 8 has multiple adjustment slots 37. The end of the first bolt 20 is inserted into the adjustment slot 37. The disassembly frame 9 is provided with a second fixing mechanism for positioning it.

[0037] like Figure 5-7 As shown, the second fixing mechanism includes a mounting block 29 fixedly connected to the disassembly frame 9. The mounting block 29 is positioned between two vertical blocks of the disassembly frame 9. A sliding groove 30 is provided through the mounting block 29. A fixing block 31 is slidably connected in the sliding groove 30. A rotating rod 32 is rotatably connected to the side of the fixing block 31 away from the connecting pipe 24 via a bearing. A handle block 34 is fixedly connected to the end of the rotating rod 32 away from the fixing block 31. A spring 35 is fixedly connected between the handle block 34 and the mounting block 29. A limiting post 43 is fixedly connected to the rotating rod 32. The side of the fixing block 31 away from the rotating rod 32 is inclined. The inclined surface of the fixing block 31 is inclined from the rotating rod 32 towards the mounting block 29. A positioning groove 36 communicating with the sliding groove 30 is provided on the side of the mounting block 29 away from the connecting pipe 24. The limiting post 43 can be inserted into the positioning groove 36.

[0038] When in use, when the disassembly frame 9 is installed on the stabilizing column 8, the stabilizing column 8 needs to be slid into the mounting groove 23. During this process, the upper surface of the stabilizing column 8 contacts the inclined surface of the fixing block 31 and pushes the fixing block 31 to move closer to the rotating rod 32, thereby driving the fixing block 31, the rotating rod 32 and the handle block 34 to move synchronously. During this process, the spring 35 is stretched, causing the spring 35 to deform. When the stabilizing column 8 slides to abut against the top wall of the mounting groove 23, the fixing block 31 disengages from the stabilizing column 8. Under the action of the release force of the spring 35, the fixing block 31 is pushed to slide closer to the stabilizing column 8 and the upper surface of the fixing block 31 abuts against the lower surface of the stabilizing column 8, thereby restricting the disassembly frame 9 so that the disassembly frame 9 cannot move up and down or left and right, and can only slide back and forth along the direction of the stabilizing column 8.

[0039] When the first bolt 20 is rotated so that its end is inserted into the appropriate adjustment groove 37, the first bolt 20 and the adjustment groove 37 cooperate to restrict the disassembly frame 9, so that the disassembly frame 9 cannot move back and forth, but can only move up and down. In turn, the first fixing mechanism and the second fixing mechanism cooperate to fix the disassembly frame 9, so that the disassembly frame 9 cannot be displaced, thereby ensuring the stability of the cleaning mechanism in cleaning the heat exchange plate 6.

[0040] During disassembly, pull out the handle block 34, causing the handle block 34 to simultaneously drive the rotating rod 32 and the fixing block 31 to move away from the stabilizing column 8, thereby releasing the restriction of the stabilizing column 8 by the fixing block 31. In this process, the limiting column 43 is also displaced out of the mounting block 29. Then, rotate the handle block 34 to make the limiting column 43 rotate, and then push the handle block 34 to make it drive the limiting column 43 to insert into the positioning groove 36. Under the action of the release force of the spring 35, the current state of the fixing block 31 is positioned. At this time, the disassembly frame 9 can be moved upward, so that the stabilizing column 8 slides out of the mounting groove 23, thereby making the cleaning mechanism flexibly disassembled and facilitating the maintenance of the cleaning mechanism.

[0041] In this solution, the cleaning mechanism can be used to clean the heat exchange plates 6 of multiple plate evaporators, that is, multiple plate evaporators can be equipped with one cleaning mechanism.

[0042] like Figure 1-4 As shown, the rinsing mechanism includes a motor 14 fixedly installed on a water storage tank 10. The output shaft of the motor 14 is poweredly connected to a vertical rod 17 that penetrates into the water storage tank 10. Multiple stirring rods 18 are fixedly connected to the vertical rod 17. A water inlet 15 communicating with the interior of the water storage tank 10 is fixedly connected to the water inlet 10. A cover 16 is screwed onto the water inlet 15. A water outlet pipe 11 communicating with the interior of the water storage tank 10 is fixedly connected to one side of the water storage tank 10. A water pump is fixedly installed inside the water storage tank 10. The output end of the water pump is fixedly connected to the end of the water outlet pipe 11 that penetrates into the water storage tank 10. A hose is fixedly connected to the end of the water outlet pipe 11 away from the water storage tank 10. A flange pipe 12 is fixedly connected to the end of the hose away from the water outlet pipe 11.

[0043] In use, the descaling agent is poured into the water storage tank 10 through the inlet 15. Then, the motor 14 is started to drive the vertical rod 17 and the stirring rod 18 to stir the water and agent in the water storage tank 10, ensuring thorough mixing. The water pump is then started, and the pump transmits the agent mixture in the water storage tank 10 through the outlet pipe 11, hose, and flange pipe 12 to the inlet or outlet, allowing the agent mixture to enter between the heat exchange plates 6. After standing for a period of time, the agent can dissolve the scale in the heat exchange plates 6, thus preventing the formation of large amounts of scale. Cleaning the heat exchange plates does not require disassembling the entire evaporator, making the operation simple and labor-saving, thereby improving the service life of the plate evaporator and its practicality.

[0044] like Figure 1-4 As shown, multiple clamping bolts 7 are provided between the fixed clamping plate 1 and the movable clamping plate 2. Support plates 13 are fixedly connected to opposite sides of the water storage tank 10. Handles are fixedly connected to the support plates 13. Two limiting grooves 19 are provided on the heat exchange plates 6, and the limiting grooves 19 are slidably connected to the crossbar 5. The limiting grooves 19 are used to limit the movement of the heat exchange plates 6.

[0045] By adjusting the clamping bolt 7, the distance between the fixed clamping plate 1 and the movable clamping plate 2 can be adjusted, so that the fixed clamping plate 1 and the movable clamping plate 2 can clamp the heat exchange plate 6 located between them, so that the heat exchange plate 6 is tightly fitted with the heat exchange plate 6.

[0046] The support plate 13 is used to support the water storage tank 10 so that the water storage tank 10 can be placed on the mounting bracket 3.

[0047] like Figure 4 As shown, multiple mounting frames 39 are fixedly connected to the connecting pipe 24. A connecting block 40 is slidably connected inside the mounting frame 39. A connecting hole 41 is opened through one side of the connecting block 40. A second bolt 38 is threadedly connected to the mounting frame 39. The end of the second bolt 38 is inserted into the connecting hole 41. A connecting plate 42 is fixedly connected to the side of the connecting block 40 away from the connecting pipe 24. A brush 33 is fixedly connected to the side of the connecting plate 42 away from the connecting block 40.

[0048] Initially, the brush 33 is not installed on the connecting pipe 24. When the scale on the heat exchange plate 6 is stubborn, the brush 33 can be installed on the connecting pipe 24 to clean the heat exchange plate 6. First, slide the connecting block 40 into the mounting frame 39, rotate the second bolt 38 so that its end is inserted into the connecting hole 41, thereby fixing the connecting block 40 in the mounting frame 39. Then, fix the connecting plate 42 and the brush 33 to complete the installation of the brush 33. Push the heat exchange plate 6 so that one side of the heat exchange plate 6 abuts against the brush 33. At this time, start the cleaning mechanism, which can drive the brush 33 to reciprocate around the center of the positioning shaft 28, thereby driving the brush 33 to clean one side of the heat exchange plate 6 and remove the scale on the heat exchange plate 6.

[0049] In this plan, the chemical mixture or cleaning solution usually refers to a mixture of citric acid and water.

[0050] In this solution, the fixed clamping plate 1, the movable clamping plate 2, and the heat exchange plate 6 are all existing publicly available technologies, and will not be described in detail here.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
