Description
Technical Field
[0001] This utility model belongs to the technical field of cleaning devices, and in particular relates to an anti-scaling plate heat exchanger for MVR evaporators. Background Technology
[0002] With the increasing demand for high-efficiency and energy-saving evaporation technology in fields such as industrial wastewater treatment and chemical purification, MVR evaporators, with their advantages of low energy consumption and high evaporation efficiency, have become the core equipment for treating high-salt and high-hardness wastewater and concentrating materials. As a key heat exchange component of MVR evaporators, the heat exchange efficiency and anti-scaling performance of plate heat exchangers directly determine the stable operation capability and processing cost of the entire MVR system. High-efficiency heat exchange can reduce system energy consumption, and reducing scaling can avoid frequent equipment shutdowns for cleaning, ensuring continuous production.
[0003] However, when using existing plate heat exchangers, it is not convenient to adjust the spray angle of the nozzles during cleaning, making it difficult to effectively remove dirt from different locations. This results in some areas being not thoroughly cleaned, which affects the heat exchange efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide an anti-scaling plate heat exchanger for MVR evaporators. By setting an angle adjustment part, it solves the problem that existing plate heat exchangers are difficult to clean because it is not convenient to adjust the spray angle of the nozzle during cleaning, making it difficult to effectively remove dirt from different locations, resulting in some areas being affected by incomplete cleaning and thus affecting heat exchange efficiency.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an anti-scaling plate heat exchanger for an MVR evaporator, comprising a base plate one, a base plate two disposed on top of the base plate one, and a plate heat exchanger mounted on top of the base plate one. It also includes: an angle adjustment section disposed on top of the base plate two; a height adjustment section mounted on top of the base plate two; the angle adjustment section includes an angle adjustment assembly disposed above the base plate one; and a power assembly mounted above the base plate one. The angle adjustment assembly includes a protective shell disposed above the base plate one, and a rotating mechanism is fixedly connected to the inner wall of the protective shell. Shaft 1, the outer wall of the shaft rotatably connected to a half gear, the protective shell through which a rack meshes with the half gear; the rack and the protective shell are slidably connected. The plate heat exchanger is a ModelBR1.6 plate heat exchanger, the working principle of which is: it consists of a number of corrugated thin plates arranged at certain intervals, sealed around the perimeter by gaskets, and then pressed together by a frame and a pressing screw. The four corner holes of the plates and gaskets form the fluid distribution pipe and the collection pipe, cleverly separating the hot and cold fluids, allowing them to flow in the channels on both sides of each plate, and then exchanging heat through the plates. Its plate corrugations adopt a double herringbone structure, which can enhance the turbulence when the medium passes through. It not only has high heat transfer efficiency, but also excellent pressure resistance. During operation, the low temperature fluid is filtered to remove dirt, and then pressurized by the circulating pump to enter the heat exchanger. It absorbs the heat released by the heat medium in the primary heat exchange and, after reaching the set temperature of the water supply, flows to the heating network to provide heating for users. The heat source enters the heat exchanger through the filter and regulating valve to release heat. After being heated by the heat medium, it returns to the heat source and participates in the circulating heat exchange again.
[0006] Furthermore, the power assembly includes a fixing block fixedly connected to the inner rear wall of the protective shell. A hydraulic cylinder is fixedly connected to the top of the fixing block, and a connecting block is fixedly connected to the output shaft of the hydraulic cylinder. The front side of the connecting block is fixedly connected to a rack, and a spraying element is provided on the half gear. The spraying element is located on the front side of the protective shell. The spraying element includes a support plate fixedly connected to the half gear. Two nozzles are fixedly connected to the front side of the support plate, and two hoses pass through the support plate. The two hoses are respectively connected to the two nozzles. The two nozzles are arranged in a mirror image on the support plate.
[0007] Furthermore, the height adjustment part includes a height adjustment assembly disposed on the second base plate; a sliding assembly disposed on the second base plate, the height adjustment assembly including a support block fixedly connected to the top of the second base plate, a motor fixedly connected to the rear side of the support block, the output shaft of the motor fixedly connected to a second rotating shaft via a coupling, the second rotating shaft rotatably passing through the support block, and a connecting member disposed on the second rotating shaft; the support block is located below the protective shell, the connecting member including a connecting rod fixedly connected to the outer wall of the second rotating shaft, an adjusting rod fixedly connected to the front side of the connecting rod; the outer wall of the adjusting rod contacts the inner wall of the sliding groove.
[0008] Furthermore, the sliding assembly includes two slide rails fixedly connected to the top of the base plate, and a bracket is slidably connected to the inner wall of the two slide rails. A slide groove is provided on the rear side of the bracket; the two slide rails are mirror images of each other.
[0009] This utility model has the following beneficial effects: 1. By setting up an angle adjustment unit, the protective shell of the angle adjustment component and the power component provides a stable installation and operating environment for the internal rotating shaft, half gear and rack. The meshing of the half gear and rack converts the linear motion of the hydraulic cylinder in the power component into the rotational motion of the half gear. The hydraulic cylinder of the power component drives the rack to slide through the connecting block, thereby driving the half gear and the spraying parts connected to it to rotate around the rotating shaft. The spraying angle of the nozzle can be adjusted according to the scaling condition of different areas of the plate heat exchanger to ensure that the cleaning fluid can evenly cover the radiator surface, effectively remove dirt from different locations, and avoid the heat exchange efficiency being affected by incomplete cleaning of some areas due to a fixed spraying angle. This provides an angle adjustment guarantee for the plate heat exchanger to maintain a good anti-scaling effect. 2. By incorporating a height adjustment unit, the height adjustment component, in conjunction with the sliding component, enables controllable adjustment of the overall height of the angle adjustment unit and the spray nozzle, further expanding the cleaning range. In the height adjustment component, the motor drives the connecting rod to rotate via a second rotating shaft. The adjusting rod on the connecting rod slides within the bracket groove of the sliding component, converting the rotational motion into the up-and-down sliding of the bracket along the slide rail. The two mirrored slide rails of the sliding component provide a stable sliding path for the bracket, ensuring a smooth height adjustment process. This height adjustment function can adapt to the cleaning needs of plate heat exchangers at different heights. Whether it's the upper or lower area of the radiator, the spray nozzle height can be adjusted to place it in the optimal cleaning position, avoiding cleaning blind spots due to height limitations. Combined with the angle adjustment unit, it forms comprehensive cleaning coverage, further enhancing the anti-scaling capability of the plate heat exchanger, ensuring stable operation of the overall heat exchange efficiency of the MVR evaporator, reducing the frequency of equipment downtime for cleaning due to scaling, and lowering production and maintenance costs.

The sliding assembly 32 includes two slide rails 32 fixedly connected to the top of the base plate 212. 1.

[0018] A specific application of this embodiment is as follows: In use, the ends of the two hoses 226 are connected to a high-pressure pump in a storage tank containing cleaning fluid. The high-pressure pump is turned on, and it pressurizes the cleaning fluid into the two nozzles 225 through the two hoses 226, causing the nozzles 225 to spray the cleaning fluid onto the plate heat exchanger 113 to clean its surface. When adjusting the angle of the nozzles 225, the hydraulic cylinder 222 on the fixing block 221 is opened. The hydraulic cylinder 222 retracts, causing the connecting block 223 to descend. The connecting block 223 causes the rack 214 to slide down on the protective shell 211. The half-gear 213 causes the support plate 224 to rotate upward around the rotating shaft 212, thereby driving... When the two hoses 226 are raised, the spray angle is raised accordingly. Conversely, when the hydraulic cylinder 222 is extended, the spray angle will decrease. When further adjustment of the spray range is needed, the motor 312 is turned on. The motor 312 drives the connecting rod 314 to rotate through the rotating shaft 313. The connecting rod 314 drives the bracket 322 to slide up on the two slide rails 321 through the adjusting rod 315. Conversely, the motor 312 reverses and drives the bracket 322 to decrease. The angle adjustment part 2 will rise and fall with the bracket 322. In this way, the height of the two nozzles 225 is adjusted, and the spray range is raised or lowered. This cleans the plate heat exchanger 113 and prevents scale buildup on its surface.
