Description

Technical Field

[0001] This utility model belongs to the field of MVR evaporator technology, specifically an MVR evaporator with inlet filtration function. Background Technology

[0002] MVR evaporators, or mechanical vapor recompression evaporators, utilize low-temperature and low-pressure steam technology and clean energy to generate steam, separating water from the medium. This internationally advanced evaporation technology represents an upgraded replacement for traditional evaporators. During the use of MVR evaporators, the liquid to be treated typically contains a certain amount of impurities, such as solid particles and suspended matter. When this impurity-laden liquid enters the evaporator directly from the inlet, the impurities easily accumulate in the pipes and heating elements. This not only affects the normal flow of the liquid and reduces evaporation efficiency but can also lead to pipe blockage, increasing maintenance costs and repair frequency. In severe cases, it can even affect the normal operation of the evaporator and shorten its lifespan. Currently, existing MVR evaporators use filter plates at the inlet to filter impurities. However, these filter plates typically require disassembly and cleaning after prolonged use, making the cleaning process cumbersome. Repeated disassembly and reassembly significantly impact the efficiency of the MVR evaporator and hinder its optimal use. Utility Model Content

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-3As shown, this utility model provides a technical solution: an MVR evaporator with inlet filtration function, including an MVR evaporator body 1. An inlet tank 2 is connected to the left side of the MVR evaporator body 1. The inlet tank 2 is a pretreatment space for the liquid to be treated before it enters the MVR evaporator body 1. A filter tank 3 is fixedly installed on the inner wall of the inlet tank 2. The filter tank 3 is used to accommodate filter components to intercept and filter impurities in the liquid. A filter disc 4 is fixedly installed on the inner wall of the filter tank 3. The filter disc 4 is the core component for realizing the filtration function; its surface is densely covered with filter holes, which can effectively block impurities from entering the evaporator body. A fixing bracket 5 is fixedly installed on the inner wall of the inlet tank 2, providing a mounting support for subsequent components. A rotating horizontal column 6 is slidably mounted on the top of the fixed bracket 5. The rotating horizontal column 6 can slide flexibly on the fixed bracket 5, preparing to drive the cleaning components to rotate. A rotating gear 7 is fixedly installed on the inner side of the outer surface of the rotating horizontal column 6. The rotating gear 7 is used to transmit power and drive the rotating horizontal column 6 to rotate. A cleaning disc 8 is fixedly installed on the right side of the rotating horizontal column 6. The cleaning disc 8 rotates with the rotating horizontal column 6, driving the cleaning scraper 9 to clean the filter disc 4. Two sets of cleaning scrapers 9 are fixedly installed on the right side of the cleaning disc 8. Both scrapers are made of rubber, which has good flexibility and wear resistance, and can effectively scrape off impurities adhering to the surface of the filter disc 4 without damaging it. The left side of the rotating horizontal column 6 is fixed... A stabilizing disc 10 is installed to ensure the stability of the rotating horizontal column 6 during rotation. A compression spring 11, which abuts against the left side of the water inlet tank 2, is fixedly installed on the right side of the stabilizing disc 10. The compression spring 11 provides a certain preload to the rotating horizontal column 6, ensuring a tight fit between the rotating horizontal column 6 and other components. A connecting horizontal plate 12 is rotatably mounted on the left side of the stabilizing disc 10. The connecting horizontal plate 12 connects the stabilizing disc 10 and the positioning horizontal plate 13, enabling linkage between components. A positioning horizontal plate 13, connected to the left side of the water inlet tank 2, is slidably mounted in the middle of the connecting horizontal plate 12. The positioning horizontal plate 13 positions and guides the connecting horizontal plate 12, allowing it to slide within a specified range. A positioning rod 14 is inserted through the middle of the connecting horizontal plate 12 and the positioning horizontal plate 13, which is used to fix the relative position of the connecting horizontal plate 12 and the positioning horizontal plate 13 to ensure the stability of the structure. The outer surface of the positioning horizontal plate 13 is provided with a positioning through hole, the size of which is adapted to the size of the positioning rod 14 to ensure that the positioning rod 14 can be accurately inserted into the positioning through hole to achieve stable positioning. An elliptical through hole is provided in the middle of the connecting horizontal plate 12, and the positioning horizontal plate 13 slides inside the elliptical through hole. The design of the elliptical through hole provides a certain amount of room for the sliding of the positioning horizontal plate 13, making the structure more flexible. A slidable pull column 15 is provided on the upper surface of the water inlet tank 2. The pull column 15 is used to transmit external force and drive the U-shaped rack plate 17 to move.A force spring 16, connected to the upper surface of the water inlet tank 2, is fixedly installed on the outer surface of the pull column 15. The force spring 16 acts as a buffer and reset mechanism during the movement of the pull column 15. A U-shaped rack plate 17 is fixedly installed on the lower surface of the pull column 15. The rotating gear 7 meshes with the U-shaped rack plate 17. Through this rack and pinion transmission method, the linear motion of the pull column 15 is converted into the rotation of the rotating gear 7, which in turn drives the rotating cross column 6 and the cleaning components to rotate.

[0022] The working principle of this utility model is as follows:

[0023] S1. The liquid to be treated enters from the water inlet tank 2 and is filtered by the filter disc 4 in the filter tank 3. Impurities are intercepted on the surface of the filter disc 4. The filtered liquid enters the evaporator through the connecting channel between the water inlet tank 2 and the MVR evaporator body 1 for evaporation treatment.

[0024] S2. When impurities accumulate on the surface of the filter disc 4, causing blockage and affecting the liquid filtration effect, the connecting horizontal plate 12 and the stabilizing disc 10 are controlled to drive the rotating horizontal column 6 and the cleaning disc 8 to move to the right, so that the cleaning scraper 9 is in close contact with the filter disc 4. Then, the column 15 is pulled upward, and the column 15 slides upward against the elastic force of the force spring 16, which drives the U-shaped rack plate 17 to move upward. Since the rotating gear 7 meshes with the U-shaped rack plate 17, the upward movement of the U-shaped rack plate 17 drives the rotating gear 7 to rotate. The rotating gear 7 drives the rotating horizontal column 6 to rotate, and the rotating horizontal column 6 drives the cleaning disc 8 to rotate. The cleaning scraper 9 on the cleaning disc 8 rotates accordingly to scrape and clean the impurities on the surface of the filter disc 4, remove the impurities, and restore the filtration performance of the filter disc 4.

[0025] S3. After cleaning, release the pull column 15. Under the elastic force of the force spring 16, pull the column 15 upward to reset. The U-shaped rack plate 17 also moves upward. The rotating gear 7 and the rotating horizontal column 6 stop rotating. The cleaning scraper 9 stops cleaning and waits for the next cleaning operation. Then, control the connecting horizontal plate 12 and the stabilizing disc 10 to drive the rotating horizontal column 6 and the cleaning disc 8 to move to the left, so that the cleaning scraper 9 separates from the filter disc 4. The positioning rod 14 passes through the connecting horizontal plate 12 and is inserted into the positioning horizontal plate 13 to position the cleaning disc 8 and the cleaning scraper 9. Then the filter disc 4 can be used normally for filtration.

[0026] In summary, this MVR evaporator with inlet filtration function, through the connection plate 12 and the rotating column 6, moves the cleaning disc 8 and cleaning scraper 9 inward to contact the filter disc 4. In conjunction with the pulling column 15, the U-shaped rack plate 17 engages with the rotating gear 7, driving the cleaning scraper 9 to clean the filter disc 4. This can quickly remove impurities from the surface of the filter disc 4. The operation is simple and convenient, greatly improving the cleaning efficiency of the filter disc 4, and thus enhancing the utilization efficiency of the MVR evaporator.

[0027] The MVR evaporator with inlet filtration function uses a positioning rod 14 that passes through the connecting horizontal plate 12 and is inserted into the positioning horizontal plate 13 to position the cleaning disc 8 and cleaning scraper 9. This provides a better positioning effect for the cleaning disc 8 and cleaning scraper 9, making it easier to clean the filter disc 4, making the entire cleaning structure more reliable, and further ensuring the stable operation of the MVR evaporator.
