Description

Plate heat exchanger cleaning device Technical Field

[0001] This utility model relates to the field of heat exchanger cleaning technology, specifically to a plate heat exchanger cleaning device. Background Technology

[0002] Plate heat exchangers are high-efficiency heat exchange devices made of stacked corrugated metal plates, widely used in liquid-liquid and liquid-vapor heat exchange scenarios. During long-term use, dust from the environment will continuously adhere to the metal plates of the plate heat exchanger, thus affecting its heat exchange efficiency. Therefore, regular cleaning is necessary.

[0003] The State Intellectual Property Office website published a plate heat exchanger cleaning device with publication number 202321187328.X. The heat exchanger is equipped with a base for placing the plate heat exchanger, and then water is sprayed from the nozzle for cleaning, which has an effective cleaning effect. However, this cleaning requires the entire plate heat exchanger to be disassembled and placed on the base. The production line needs to be stopped beforehand, which affects the production efficiency. Moreover, it is relatively time-consuming and labor-intensive to disassemble the entire plate heat exchanger and then move it to the base. Summary of the Invention

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A plate heat exchanger cleaning device includes two parallel support frames, a bottom beam fixed on each support frame, a top beam directly above the bottom beam, a lead screw three installed between the bottom beam and the top beam at the left and right positions, a slider three mounted on the lead screw three and sliding along the lead screw three, a brush roller installed between the slider three at the left and right positions, brush bristles fixed on the brush roller, a motor four mounted on the slider three at the left end of the brush roller, the output end of the motor four being fixedly connected to the brush roller at the corresponding position, and the plate heat exchanger body located between the lead screw three at the left and right positions.

[0006] Furthermore, a lead screw 1 is installed above the bottom beam, and a slider 1 that slides along the lead screw 1 is installed on the lead screw 1. A lead screw 2 is installed above the top beam, and a slider 2 that slides along the lead screw 2 is installed on the lead screw 2. The two ends of a lead screw 3 are installed with corresponding sliders 1 and 2. Shaft seats are fixed at the top of the bottom beam corresponding to the two ends of lead screw 1, the top of the top beam corresponding to the two ends of lead screw 2, and the two ends of slider 2 corresponding to the two ends of lead screw 3. The two ends of lead screw 1, lead screw 2, and lead screw 3 are installed with corresponding shaft seats. The cooperation between lead screw 1 and slider 1, and lead screw 2 and slider 2, allows the brush roller to move horizontally along lead screw 1 and lead screw 2, thereby adjusting its position to suit the cleaning position of the plate heat exchanger body.

[0007] Furthermore, a motor is installed at the front end of the bottom beam corresponding to the end of lead screw one, and the output end of motor one is fixedly connected to lead screw one at the corresponding position. A motor is installed at the front end of the top beam corresponding to the end of lead screw two, and the output end of motor two is fixedly connected to lead screw two at the corresponding position. A motor is installed on the slider two at the top end of lead screw three, and the output end of motor three is fixedly connected to lead screw three at the corresponding position. The motor drive method is simple and reliable, does not require manual rotation, and improves the degree of automation.

[0008] Furthermore, each end of the slider three is fixed with a fastener, and a retaining ring is bolted to the fastener. The two ends of the brush roller are installed through the fastener and the retaining ring. This allows for easy replacement of the brush roller.

[0009] Furthermore, support sleeves are installed at both ends of the top beam, and support rods are installed at both ends of the bottom beam corresponding to the positions of the support sleeves. The top part of the support rod extends into the corresponding support sleeve to form a movable support. Multiple equally spaced adjustment holes are opened on the support rod. A pin is installed on the bottom of the support sleeve, and the pin passes through the corresponding adjustment hole to limit and fix the support sleeve and the support rod. The top end of the support sleeve and the bottom end of the support rod are fixed to the top beam and bottom beam at the corresponding positions by fixing seats. The support sleeve and support rod cooperate to have a lifting and adjusting effect, which can adjust the height of the top beam to adapt to plate heat exchangers of different heights.

[0010] Furthermore, the lead screw three includes multiple adapter lead screws and a bottom lead screw. A shaft head is fixed to the bottom end of the bottom lead screw, and a sleeve is fixed to the top end of the adapter lead screw. The sleeve and shaft head are installed with corresponding bearing seats. A protruding sleeve is fixed to the middle of the bottom end of the adapter lead screw. A cavity is pre-set between the protruding sleeve and the adapter lead screw at the corresponding sleeve position. The inner side of the sleeve and the outer side of the protruding sleeve are provided with mating threads. The number of multiple adapter lead screws can be increased or decreased according to the height of the top beam to adapt to the installation, eliminating the need for complete replacement and facilitating adjustment.

[0011] Furthermore, a bottom reinforcing beam is fixed between the front ends of the bottom beams at the left and right positions, and a top reinforcing beam is fixed between the front and rear ends of the top beams at the left and right positions. The reinforcing beams can increase the stability of the entire device frame.

[0012] Furthermore, casters are fixed at both ends of the bottom of the bottom beam. The casters facilitate movement, and combined with the bottom reinforcing beam located only at the front end of the bottom beam, a pushing device can be used to fit the installed plate heat exchanger body.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a combination of multiple lead screws and sliders to control and adjust the position of the brush roller, thereby enabling reliable cleaning of the front, top, and back surfaces of the plate heat exchanger without disassembling the entire heat exchanger, thus not affecting normal production and saving cleaning time.

[0015] 2. In this utility model, the height of the top beam can be adjusted by combining the support sleeve and the support rod, thereby adapting to heat exchangers of different heights and improving the flexibility of use.

[0016] 3. In this utility model, multiple interconnectable adapter screws are used as screw three, which can quickly adapt to the height adjustment of the top beam without affecting the movement control of the brush roller.

[0017] 4. In this utility model, the overall stability of the device is increased by reinforcing beams, and it is used with casters, which can directly push the device to fit the heat exchanger without extensive disassembly and installation, making it convenient to use. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] This application provides a plate heat exchanger cleaning device, mainly solving the problem that the prior art requires the entire plate heat exchanger to be disassembled and transported when cleaning it, which affects production efficiency and is time-consuming and labor-intensive. The following technical solution is provided, which will be explained in detail below with reference to Figures 1-6:

[0027] A plate heat exchanger cleaning device includes a support frame 1, which has two parallel supports on the left and right. A bottom beam 2 is fixed on each of the two support frames 1. A lead screw 3 is installed above each bottom beam 2. A slider 4 that slides along the lead screw 3 is installed on the lead screw 3. A motor 5 is installed at the front end of the bottom beam 2 corresponding to the end of the lead screw 3. The output end of the motor 5 is fixedly connected to the lead screw 3 at the corresponding position.

[0028] A top beam 6 is set directly above the bottom beam 2. A lead screw 7 is installed above each top beam 6. A slider 8 that slides along the lead screw 7 is installed on the lead screw 7. A motor 9 is installed at the front end of the top beam 6 corresponding to the end of the lead screw 7. The output end of the motor 9 is fixedly connected to the lead screw 7 at the corresponding position.

[0029] A lead screw 10 is installed between slider 4 and slider 8 on the left and right sides. A slider 11 that slides along the lead screw 10 is installed on the lead screw 10. A motor 12 is installed on slider 8 at the top position of the lead screw 10. The output end of the motor 12 is fixedly connected to the lead screw 10 at the corresponding position.

[0030] A brush roller 13 is installed between the left and right sliders 11. Brush bristles 14 are fixed on the brush roller 13. A motor 15 is installed on the left slider 11 of the brush roller 13. The output end of the motor 15 is fixedly connected to the brush roller 13 at the corresponding position. The plate heat exchanger body 33 is located between the left and right lead screws 10. The top of the bottom beam 2 corresponds to the two ends of the lead screw 3, the top of the top beam 6 corresponds to the two ends of the lead screw 7, and the slider 28 corresponds to the two ends of the lead screw 10. The two ends of the lead screw 3, lead screw 7, and lead screw 10 are installed with the corresponding shaft seats 25.

[0031] When in use, extend the support frame 1 to the left and right sides of the plate heat exchanger body 33, and then carry out the cleaning operation. During cleaning, first control the motor 1 5 and the motor 2 9 to drive the slider 1 4 to slide horizontally along the lead screw 1 3 and the slider 2 8 to slide horizontally along the lead screw 2 7, and move the brush roller 13 forward to make enough space for the plate heat exchanger body 33 to be placed. At the same time, adjust the brush roller 13 to be close to the front and rear plates of the plate heat exchanger body 33 so that the bristles 14 can touch the plate heat exchanger body 33. Then control the motor 3 12 to drive the slider 3 11 to slide up and down along the lead screw 3 10.

[0032] Simultaneously, motor 415 is activated, driving brush roller 13 to rotate. This causes the bristles 14 to repeatedly brush and clean the front surface of the plate heat exchanger body 33. While brushing, water can be sprayed separately to improve the cleaning effect. After the front surface is cleaned, motor 312 drives brush roller 13 to move upwards, positioning it to align with the top surface of the plate heat exchanger body 33. At this point, motors 11 and 29 operate, driving brush roller 13 to move horizontally, causing the bristles 14 to repeatedly brush and clean the top surface of the plate heat exchanger body 33. After the top surface is cleaned, brush roller 13 is adjusted to the back surface of the plate heat exchanger body 33 for brushing and cleaning. This process cleans the front, back, and top surfaces of the plate heat exchanger body 33 without disassembling it, thus not affecting normal production and saving cleaning time.

[0033] In some embodiments, a buckle 16 is fixed at both ends of the slider 11 corresponding to the brush roller 13, and a buckle ring 17 is bolted to the buckle 16. The two ends of the brush roller 13 are installed by the buckle 16 and the buckle ring 17.

[0034] The engagement of the buckle 17 and the buckle seat 16 forms a convenient quick-release structure, which allows the brush roller 13 to be quickly removed or replaced with a new one or other cleaning rollers.

[0035] In some embodiments, support sleeves 20 are installed at both the front and rear ends of the top beam 6, and support rods 21 are installed at both the front and rear ends of the bottom beam 2 corresponding to the positions of the support sleeves 20. The top part of the support rod 21 extends into the support sleeve 20 at the corresponding position to form a movable support. Multiple adjustment holes 23 with equal spacing are opened on the support rod 21. A pin 22 is installed on the support sleeve 20 near the bottom position. The pin 22 passes through the adjustment hole 23 at the corresponding position to limit and fix the support sleeve 20 and the support rod 21. The top end of the support sleeve 20 and the bottom end of the support rod 21 are fixed to the top beam 6 and the bottom beam 2 at the corresponding positions through the fixing seat 32.

[0036] The support sleeve 20 and the support rod 21 are supported by the cooperation of the pin 22 and the adjustment hole 23, which has the effect of adjustable height. The height of the top beam 6 can be adjusted to adapt to heat exchangers of different heights and sizes, thereby improving the flexibility of use. When the top beam 6 is raised, the screw rod 10 can be replaced with the corresponding length.

[0037] In some embodiments, the lead screw 3 10 includes multiple adapter lead screws 26 and a bottom lead screw 27. The bottom end of the bottom lead screw 27 is fixed with a shaft head 31, and the top end of the adapter lead screw 26 is fixed with a sleeve 28. The sleeve 28 and the shaft head 31 are installed with the corresponding shaft seat 25. A protruding sleeve 29 is fixed at the middle position of the bottom end of the adapter lead screw 26. A cavity 30 is preset between the protruding sleeve 29 and the adapter lead screw 26 at the position corresponding to the sleeve 28. The inner side of the sleeve 28 and the outer side of the protruding sleeve 29 are provided with mutually cooperating threads.

[0038] Multiple adapter screws 26 can be added or removed when adjusting the height of the top beam 6, thereby satisfying the linkage between screw 3 10 and the top beam 6 and the bottom beam 2. When connecting multiple adapter screws 26, the protrusions 29 of adjacent adapter screws 26 are engaged with the sleeves 28 to form a threaded connection.

[0039] In some embodiments, a bottom reinforcing beam 18 is fixed between the front ends of the bottom beam 2 at the left and right positions, and a top reinforcing beam 19 is fixed between the front and rear ends of the top beam 6 at the left and right positions. A movable wheel 24 is fixed at both ends of the bottom of the bottom beam 2.

[0040] Both the bottom reinforcing beam 18 and the top reinforcing beam 19 are used to increase the structural strength of the entire frame. The bottom reinforcing beam 18 is not set on the rear side of the bottom beam 2. With the setting of the moving wheel 24, the support sleeve 20 and support rod 21 on the left or right side of the rear end of the bottom beam 2 and the top beam 6 can be temporarily removed during use. Then, the entire device can be pushed by the moving wheel 24 so that the plate heat exchanger body 33 can be inserted into the device from the rear as a whole. Then, the temporarily removed support sleeve 20 and support rod 21 can be installed. This ensures the overall strength of the device and facilitates its use.
