Description
Technical Field
[0001] This utility model relates to an easy-to-clean plate evaporator, belonging to the technical field of plate heat exchangers. Background Technology
[0002] Plate heat exchangers, as efficient and compact heat exchange devices, are widely used in chemical, energy, and food processing industries.
[0003] During long-term operation, dust and sludge easily accumulate on the surface of plate evaporators, leading to decreased heat transfer efficiency, increased fluid resistance, and even blockage. Therefore, regular cleaning is a key aspect of ensuring equipment performance. However, traditional cleaning methods for plate heat exchangers have significant limitations. They require disassembling the plates and scrubbing or rinsing them manually, which is time-consuming and labor-intensive, increasing equipment costs and maintenance difficulty.
[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 easy-to-clean plate evaporator, which solves the problem that the cleaning methods of traditional plate heat exchangers in the prior art have significant limitations. The plates need to be disassembled and brushed or rinsed, and manual rinsing is time-consuming and laborious, which increases the equipment cost and maintenance difficulty.
[0006] The technical problem to be solved by this utility model is achieved by the following technical solution: an easy-to-clean plate evaporator, including a mounting base, a fixed clamping plate, a support block and a movable clamping plate are provided on the mounting base, and a mounting block is fixedly connected to one end of the fixed clamping plate and the support block. The mounting block is fixedly installed on the mounting base, and two guide blocks are fixedly installed between the fixed clamping plate and the support block. The movable clamping plate is slidably connected to the guide blocks. A first positioning block is provided on the fixed clamping plate, and a second positioning block is provided on the movable clamping plate. Multiple heat transfer plates are provided between the fixed clamping plate and the movable clamping plate. An installation mechanism is provided on both the fixed clamping plate and the movable clamping plate. The installation mechanism is used to install and fix the second positioning block and the first positioning block on the fixed clamping plate and the movable clamping plate respectively. A positioning tube is provided between the second positioning block and the first positioning block. The positioning tube is in the shape of an "n". Multiple nozzles communicating with it are fixedly installed on the inner side of the positioning tube. A cleaning mechanism is provided between the second positioning block and the first positioning block. The cleaning mechanism is used to drive the nozzles to clean the heat transfer plates.
[0007] By adopting the above technical solution, water is injected into the positioning tube during use. The water is then sprayed onto the heat transfer plates through the nozzles. At this time, the cleaning mechanism is activated, which moves the positioning tube along the extension direction of the guide block, thereby moving the nozzles synchronously to spray the heat transfer plates, thus cleaning them. Because the positioning tube is n-shaped, the nozzles on the positioning tube can clean the top and left and right sides of the heat transfer plates. On the one hand, this allows for more comprehensive cleaning of the heat transfer plates, increasing the cleaning range and improving the cleaning effect and efficiency. On the other hand, it eliminates the need for manual rinsing, making it more labor-saving and efficient, thereby improving the practicality of the easy-to-clean plate evaporator.
[0008] The present invention is further configured such that: guide grooves that are slidably connected to guide blocks are provided on opposite sides of the heat transfer plate, and clamping screws are provided between the fixed clamping plate and the movable clamping plate.
[0009] By adopting the above technical solution, the position of the movable clamping plate can be adjusted by rotating the nut on the clamping screw. When the movable clamping plate moves closer to the fixed clamping plate, the heat transfer plate can be clamped and fixed between the fixed clamping plate and the movable clamping plate. Therefore, by rotating the nut on the clamping screw, the distance between the fixed clamping plate and the movable clamping plate can be adjusted, thereby adjusting the distance between the heat transfer plates, which facilitates the cleaning of the heat transfer plates.
[0010] The present invention is further configured as follows: the cleaning mechanism includes a movable block disposed between the first positioning block and the second positioning block, a positioning rod that passes through the opposite sides of the connecting pipe is fixedly installed on the connecting pipe, the ends of the positioning rods are rotatably connected to the first connecting block, the first connecting block is fixedly connected to the positioning pipe, a connecting pipe communicating with the positioning pipe is fixedly connected to the positioning pipe, and a movable mechanism capable of driving the movable block to move is disposed between the first positioning block and the second positioning block.
[0011] The moving mechanism includes a first positioning rod fixed on a first positioning block and sliding through a second positioning block and a moving block. A motor is fixedly installed on one side of the first positioning block. The output shaft of the motor is poweredly connected to a first threaded rod that passes through the first positioning block. A sliding hole is opened through the second positioning block. The first threaded rod slides through the sliding hole and passes through the second positioning block. The moving block is threadedly connected to the first threaded rod.
[0012] By adopting the above technical solution, during use, a hose is connected to the connecting pipe, and the other end of the hose is connected to a water source such as a faucet. Water can be injected into the positioning pipe through the connecting pipe. Initially, the positioning pipe is in a vertical state. At this time, the position of the movable clamping plate is adjusted by rotating the nut at the upper end of the clamping screw, so that the movable clamping plate and the fixed clamping plate are far apart, as shown in the figure below. The heat transfer plates are slidably connected between the two guide blocks through the guide groove, so the heat transfer plates can be slid to make them far apart, creating a gap between the heat transfer plates. At this time, water is injected into the connecting pipe through the hose. The water enters the positioning pipe and is sprayed onto the heat transfer plates through the nozzle. Because the positioning pipe is n-shaped, the nozzle on the positioning pipe can clean the top and left and right sides of the heat transfer plates. On the one hand, the cleaning of the heat transfer plates is more comprehensive, thereby improving the cleaning effect of the heat transfer plates. On the other hand, manual rinsing is not required, which is more labor-saving and efficient, thereby improving the practicality of the easy-to-clean plate evaporator.
[0013] When the motor is started, it can drive the first threaded rod to rotate. Because the moving block is threadedly connected to the first threaded rod, the rotation of the first threaded rod can drive the moving block to reciprocate along the axis of the first positioning rod. The first positioning rod has a limiting and stabilizing effect on the moving block, thereby driving the positioning tube installed on the moving block to move synchronously. During the movement of the positioning tube, it can drive the nozzle to spray and wash the heat transfer plates, thereby increasing the cleaning range of the heat transfer plates, improving the cleaning effect and efficiency of the heat transfer plates, and thus increasing the practicality of the plate evaporator.
[0014] The present invention is further configured such that: the installation mechanism includes a connecting groove formed on the movable clamping plate; the first positioning block and the second positioning block are each provided with an installation groove; the first positioning block and the second positioning block are slidably connected to the fixed clamping plate and the movable clamping plate respectively through the installation groove; the first positioning block and the second positioning block are each provided with a slot communicating with the installation groove; an installation frame is fixedly connected to both the fixed clamping plate and the movable clamping plate; a fixed rod is rotatably connected to the installation frame; a second connecting block is fixedly connected to the fixed rod; a slotted block that can be inserted into the slot is fixedly connected to the second connecting block; a connecting post is fixedly connected to the installation frame; a spring is sleeved on one end of the fixed rod; the inner end of the spring is fixedly connected to the fixed rod; and the outer end of the spring is fixedly connected to the connecting post.
[0015] By adopting the above technical solution, during use, the mainspring provides support for the second connecting block and the locking block, allowing the second connecting block to maintain a slightly tilted state in the initial state (usually with an tilt angle of 10-15 degrees). At this time, the locking block abuts against the fixed or movable pressure plate. During installation, the first positioning block is fitted onto the fixed pressure plate through the mounting groove, and the second positioning block is fitted onto the connecting groove of the movable pressure plate through the mounting groove. Since the mounting mechanisms on the fixed and movable pressure plates are structurally identical, for ease of description, the following mainly describes the mounting mechanism on the fixed pressure plate. During the process of the first positioning block being fitted onto the fixed pressure plate, the lower surface of the first positioning block contacts the tilted surface of the locking block, and the first positioning block applies a pushing force to the tilted surface of the locking block, causing the locking block and the second connecting block to rotate around the axis of the fixed rod. During this process, the mainspring undergoes contraction and deformation. When the first positioning block slides downward until the upper surface of the fixed pressure plate abuts against the top wall of the mounting groove... At this point, the slot and the block are aligned. Under the release force of the spring, the block is inserted into the slot, causing its lower surface to abut against the bottom wall of the slot. The block and slot then restrict the first positioning block, preventing it from moving left or right and from easily moving upwards. This allows the first and second positioning blocks to be mounted on the fixed and movable pressure plates, facilitating the installation of the cleaning mechanism. Installation is convenient; disassembly is also easy, requiring only the second connecting block to slide the block out of the slot. This allows the cleaning mechanism to be used to clean other plate evaporators, further enhancing the practicality and flexibility of easy-to-clean plate evaporators.
[0016] The present invention is further configured such that: a fixing bolt is threadedly connected to the first connecting block, and the end of the fixing bolt abuts against the positioning rod.
[0017] By adopting the above technical solution, the fixing bolt is rotated to make it tightly abut against the outer surface of the positioning rod, thereby increasing the friction between the fixing bolt and the positioning rod and fixing the first connecting block. This prevents the first connecting block from rotating around the axis of the positioning rod, thus positioning the positioning tube and fixing it in a vertical or horizontal state. When the positioning tube is fixed in a horizontal state, it can be stored, while when the positioning tube is fixed in a vertical state, it facilitates the cleaning of the heat transfer plates.
[0018] The beneficial effects of this invention are as follows: Water is injected into the connecting pipe through a flexible hose. The water enters the positioning pipe and is sprayed onto the heat transfer plates through a nozzle. Because the positioning pipe is n-shaped, the nozzle on the positioning pipe can clean the top and left and right sides of the heat transfer plates, resulting in a more comprehensive cleaning. Starting the motor can drive the first threaded rod to rotate. Because the moving block is threadedly connected to the first threaded rod, the rotation of the first threaded rod can drive the moving block to reciprocate along the axis of the positioning rod. The positioning rod has a limiting and stabilizing effect on the moving block, thereby driving the positioning pipe installed on the moving block to move synchronously. During the movement of the positioning pipe, the nozzle can spray and wash the heat transfer plates, thereby increasing the cleaning range of the heat transfer plates, improving the cleaning effect and efficiency of the heat transfer plates, and thus increasing the practicality of the plate evaporator.

[0027] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following details... Figure 1-6As shown, this utility model is further illustrated.
[0028] like Figure 1-4 As shown, this utility model is an easy-to-clean plate evaporator, including a mounting base 1. The mounting base 1 is provided with a fixed clamping plate 2, a support block 12, and a movable clamping plate 3. One end of both the fixed clamping plate 2 and the support block 12 is fixedly connected to a mounting block 4. The mounting block 4 is fixedly installed on the mounting base 1 by bolts. Two guide blocks 14 are fixedly installed between the fixed clamping plate 2 and the support block 12 by bolts. The movable clamping plate 3 is slidably connected to the guide blocks 14. A first positioning block 5 is provided on the fixed clamping plate 2, and a second positioning block 6 is provided on the movable clamping plate 3. Multiple heat transfer plates 17 are arranged between the clamping plates 3. Both the fixed clamping plate 2 and the movable clamping plate 3 are equipped with mounting mechanisms. The mounting mechanisms are used to install and fix the second positioning block 6 and the first positioning block 5 on the fixed clamping plate 2 and the movable clamping plate 3, respectively. A positioning tube 18 is arranged between the second positioning block 6 and the first positioning block 5. The positioning tube 18 is in the shape of an "n". Multiple nozzles 23 are fixedly installed on the inner side of the positioning tube 18 and communicate with it. A cleaning mechanism is arranged between the second positioning block 6 and the first positioning block 5. The cleaning mechanism is used to drive the nozzles 23 to clean the heat transfer plates 17.
[0029] In use, water is injected into the positioning tube 18, and the water is sprayed onto the heat transfer plates 17 through the nozzle 23. At this time, the cleaning mechanism is activated, which drives the positioning tube 18 to move along the extension direction of the guide block 14, thereby driving the nozzle 23 to move synchronously to spray the heat transfer plates 17, thus cleaning the heat transfer plates 17. Because the positioning tube 18 is n-shaped, the nozzle 23 on the positioning tube 18 can clean the top and left and right sides of the heat transfer plates 17. On the one hand, it can clean the heat transfer plates 17 more thoroughly, thereby increasing the cleaning range of the heat transfer plates 17 and improving the cleaning effect and efficiency. On the other hand, it eliminates the need for manual rinsing, making it more labor-saving and efficient, thereby improving the practicality of the easy-to-clean plate evaporator.
[0030] like Figure 1-6 As shown, guide grooves 16 that are slidably connected to guide blocks 14 are provided on opposite sides of heat transfer plate 17, and clamping screws 13 are provided between fixed clamping plate 2 and movable clamping plate 3.
[0031] The position of the movable clamping plate 3 can be adjusted by rotating the nut on the clamping screw 13. When the movable clamping plate 3 moves closer to the fixed clamping plate 2, the heat transfer plate 17 can be clamped and fixed between the fixed clamping plate 2 and the movable clamping plate 3. Therefore, by rotating the nut on the clamping screw 13, the distance between the fixed clamping plate 2 and the movable clamping plate 3 can be adjusted, thereby adjusting the distance between the heat transfer plates 17 and the heat transfer plates 17, which facilitates the cleaning of the heat transfer plates 17.
[0032] like Figure 1-4 As shown, the cleaning mechanism includes a movable block 9 disposed between the first positioning block 5 and the second positioning block 6. A second positioning rod 20 is fixedly installed on the connecting pipe 19, passing through its opposite sides. The ends of the second positioning rods 20 are rotatably connected to a first connecting block 21. The first connecting block 21 is fixedly connected to the positioning pipe 18. The positioning pipe 18 is vertically mounted on the outside of the heat transfer plate 17. A connecting pipe 19 communicating with the positioning pipe 18 is fixedly connected to the positioning pipe 18. A movable mechanism capable of driving the movable block 9 to move is disposed between the first positioning block 5 and the second positioning block 6.
[0033] like Figure 3 As shown, the moving mechanism includes a first positioning rod 8 fixed on the first positioning block 5 and sliding through the second positioning block 6 and the moving block 9. A motor 10 is fixedly installed on one side of the first positioning block 5. The output shaft of the motor 10 is poweredly connected to a first threaded rod 7 that passes through the first positioning block 5. A sliding hole 11 is provided through the second positioning block 6. The first threaded rod 7 slides through the second positioning block 6 through the sliding hole 11. The moving block 9 is threadedly connected to the first threaded rod 7.
[0034] In use, connect the hose to the connecting pipe 19, and connect the other end of the hose to a water source such as a faucet. Water can be injected into the positioning pipe 18 through the connecting pipe 19. Initially, the positioning pipe 18 is in a vertical position. At this time, rotate the nut at the upper end of the clamping screw 13 to adjust the position of the movable clamping plate 3, so that the movable clamping plate 3 and the fixed clamping plate 2 are moved away from each other, as shown in the figure below. The heat transfer plate 17 is slidably connected between the two guide blocks 14 through the guide groove 16, so the heat transfer plate 17 can be slid to move away from each other, thus... A gap is created between the heat transfer plates 17. At this time, water is injected into the connecting pipe 19 through the hose. The water enters the positioning pipe 18 and is sprayed onto the heat transfer plates 17 through the nozzle 23. Because the positioning pipe 18 is n-shaped, the nozzle 23 on the positioning pipe 18 can clean the top and left and right sides of the heat transfer plates 17. On the one hand, the cleaning of the heat transfer plates 17 can be more comprehensive, thereby improving the cleaning effect of the heat transfer plates 17. On the other hand, it eliminates the need for manual rinsing, making it more labor-saving and efficient, thereby improving the practicality of the easy-to-clean plate evaporator.
[0035] When the motor 10 is started, it can drive the first threaded rod 7 to rotate. Because the moving block 9 is threadedly connected to the first threaded rod 7, the rotation of the first threaded rod 7 can drive the moving block 9 to reciprocate along the axis of the first positioning rod 8. The first positioning rod 8 has a limiting and stabilizing effect on the moving block 9, thereby driving the positioning tube 18 installed on the moving block 9 to move synchronously. During the movement of the positioning tube 18, it can drive the nozzle 23 to spray and wash the heat transfer plate 17, thereby increasing the cleaning range of the heat transfer plate 17, improving the cleaning effect and efficiency of the heat transfer plate 17, and thus increasing the practicality of the plate evaporator.
[0036] like Figure 5-6 As shown, the installation mechanism includes a connecting groove 15 formed on the movable clamping plate 3. The first positioning block 5 and the second positioning block 6 each have an installation groove 31. The first positioning block 5 and the second positioning block 6 are slidably connected to the fixed clamping plate 2 and the movable clamping plate 3 respectively through the installation grooves 31. The first positioning block 5 and the second positioning block 6 each have a slot 30 communicating with the installation groove 31. A mounting bracket 24 is fixedly connected to both the fixed clamping plate 2 and the movable clamping plate 3. A fixed rod 25 is rotatably connected to the mounting bracket 24. A second connecting block 26 is fixedly connected to the fixed rod 25. The second connecting block 26 is initially in a certain state. In the tilted state, a card block 29 that can be inserted into the card slot 30 is fixedly connected to the second connecting block 26. The card block 29 abuts against the fixed clamping plate 2 or the movable clamping plate 3. The side of the card block 29 that abuts against the fixed clamping plate 2 or the movable clamping plate 3 is an inclined surface. The inclined surface of the connecting pipe 19 is inclined towards the second connecting block 26 from the direction of the mounting bracket 24 to the moving block 9. A connecting post 27 is fixedly connected to the mounting bracket 24. A spring 28 is sleeved on one end of the fixing rod 25. The inner end of the spring 28 is fixedly connected to the fixing rod 25, and the outer end of the spring 28 is fixedly connected to the connecting post 27.
[0037] In use, the spring 28 supports the second connecting block 26 and the locking block 29, so that the second connecting block 26 can be kept slightly tilted in the initial state (usually the tilt angle is 10-15 degrees). At this time, the locking block 29 abuts against the fixed pressure plate 2 or the movable pressure plate 3. During installation, the first positioning block 5 is fitted onto the fixed clamping plate 2 through the mounting groove 31, and the second positioning block 6 is fitted onto the connecting groove 15 of the movable clamping plate 3 through the mounting groove 31. Since the mounting mechanisms on the fixed clamping plate 2 and the movable clamping plate 3 are structurally identical, for ease of description, the following mainly describes the mounting mechanism on the fixed clamping plate 2. During the process of fitting the first positioning block 5 onto the fixed clamping plate 2, the lower surface of the first positioning block 5 contacts the inclined surface of the locking block 29, and the first positioning block 5 exerts a pushing force on the inclined surface of the locking block 29, pushing the locking block 29 and the second connecting block 26 to rotate around the axis of the fixed rod 25. During this process, the spring 28 is driven to contract and deform. When the first positioning block 5 slides down until the upper surface of the fixed clamping plate 2 abuts against the top wall of the mounting groove 31... At this time, the slot 30 and the block 29 are aligned. Under the release force of the spring 28, the block 29 is inserted into the slot 30, so that the lower surface of the block 29 abuts against the bottom wall of the slot 30. At this time, under the action of the block 29 and the slot 30, the first positioning block 5 is restricted, so that the first positioning block 5 cannot move left or right, and the first positioning block 5 cannot easily move upward. Thus, the first positioning block 5 and the second positioning block 6 are installed on the fixed pressing plate 2 and the movable pressing plate 3, thereby realizing the installation of the cleaning mechanism. The installation is convenient. When disassembling, it is only necessary to push the second connecting block 26 to make the block 29 slide out of the slot 30. The disassembly is convenient, so that the cleaning mechanism can clean other plate evaporators, further improving the practicality and flexibility of easy-to-clean plate evaporators.
[0038] In this design, multiple plate evaporators can be equipped with a cleaning mechanism. Furthermore, the mounting groove 31 is deep and contains friction strips to increase friction between the mounting groove 31 and the fixed or movable clamping plate 2. This prevents the first positioning block 5 or the second positioning block 6 from easily dislodging from the fixed or movable clamping plate 3. Additionally, the motor 10 is a low-speed motor that drives the positioning tube 18 at a low speed. Therefore, all these factors ensure that the first positioning block 5 and the second positioning block 6 will not easily move during the movement of the positioning tube 18, thus guaranteeing the stability of the cleaning process.
[0039] like Figure 1-4 As shown, a fixing bolt 22 is threaded onto the first connecting block 21, and the end of the fixing bolt 22 abuts against the second positioning rod 20.
[0040] By rotating the fixing bolt 22, the fixing bolt 22 is tightly pressed against the outer surface of the second positioning rod 20, thereby increasing the friction between the fixing bolt 22 and the second positioning rod 20 and fixing the first connecting block 21. This prevents the first connecting block 21 from rotating around the axis of the second positioning rod 20, thus positioning the positioning tube 18. The positioning tube 18 can be fixed in a vertical or horizontal state. When the positioning tube 18 is fixed in a horizontal state, it can be stored. When the positioning tube 18 is fixed in a vertical state, it can be convenient to clean the heat transfer plate 17.
[0041] 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.
