Description

Technical Field

[0001] This utility model relates to the field of MVR evaporation technology, specifically to an evaporation device for wastewater MVR treatment. Background Technology

[0002] With the advancement of industrialization, wastewater treatment technology is playing an increasingly important role in environmental protection, especially in industries such as chemical, pharmaceutical, and food processing, where wastewater discharge is increasing year by year, containing large amounts of organic matter, inorganic salts, heavy metals, and other harmful substances. To meet increasingly stringent environmental requirements, evaporation and concentration technology for wastewater treatment is gradually becoming an effective method.

[0003] In wastewater MVR (Mechanical Vapor Recompression) treatment technology, the evaporator plays a central role. The evaporator heats the wastewater to evaporate the water, then recovers the heat energy from the steam and reuses it in the wastewater evaporation process. This technology effectively saves energy, reduces operating costs, and minimizes wastewater pollution.

[0004] However, with long-term operation of the evaporation unit, suspended solids and impurities in the wastewater easily accumulate at the filter screen, causing clogging and affecting the normal operation of the evaporation unit. To ensure equipment stability and treatment efficiency, the cleaning and maintenance of the filter screen is crucial. However, existing wastewater MVR treatment units generally adopt a fixed filter screen design, making effective cleaning and maintenance of the filter screen difficult during equipment operation.

[0005] Due to the fixed structure of the filter screen, it cannot be easily disassembled and installed. This not only increases the time and cost of equipment downtime for maintenance but also limits the efficiency of equipment maintenance. Once the filter screen becomes clogged or damaged, complex disassembly, cleaning, and replacement operations are required, often necessitating specialized technicians and significantly impacting the production process. No solution has yet been proposed to address these technical issues. Utility Model Content

[0024] Example

[0025] Please see Figure 1-4This utility model proposes a technical solution for an evaporation device for wastewater MVR treatment: An evaporation device for wastewater MVR treatment includes a tank 1, specifically, the tank 1 is cylindrical in shape, and a feed pipe 2 is connected to the top of the tank 1. Specifically, wastewater enters the interior of the tank 1 through the feed pipe 2. A filter screen 3 is connected to the bottom of the feed pipe 2 via an installation mechanism, specifically, the filter screen 3 can filter the wastewater. The installation mechanism includes a clamping plate 4, a spring 5, a rubber column 6, and a pressing rod 7. Several openings are provided on the inner wall of the tank 1, and the clamping plate 4, spring 5, and rubber column 6 are all disposed inside the openings. The two ends of the spring 5 and the rubber column 6 are fixedly connected to the opening and the clamping plate 4, respectively, and the spring 5 is sleeved on the outer surface of the rubber column 6. Several openings are provided on the outer surface of the filter screen 3. A slot 8 matches the card plate 4. One end of the pressing rod 7 is fixedly connected to the card plate 4, and the other end of the pressing rod 7 extends to the outside of the opening. Specifically, when installing the filter screen 3, first place the filter screen 3 under the installation mechanism, push the filter screen 3 to move it upward. Under the upward force of the filter screen 3, the spring 5 and the rubber column 6 compress the card plate 4, and the card plate 4 is stored inside the opening. When the card plate 4 and the slot 8 on the filter screen 3 are at the same horizontal line, the card plate 4 extends into the slot 8 under the action of the spring 5 and the rubber column 6, thereby fixing the filter screen 3. When removing the filter screen 3, rotate the filter screen 3 so that the card plate 4 extends into the opening under the action of the spring 5 and the rubber column 6, and the card plate 4 can be taken out. The installation and removal operations are convenient.

[0026] Please see Figure 2 As shown, a cleaning mechanism is further provided above the filter screen 3. The cleaning mechanism includes a drive motor 13 and a cleaning brush 14. The drive motor 13 is installed inside the tank 1. A gear 1 is sleeved on the outer surface of the cleaning brush 14. A gear 2 is fixedly connected to the output end of the drive motor 13. Gear 1 and gear 2 mesh with each other. Gear 1 is movably connected to the tank 1.

[0027] In this embodiment, the drive motor 13 is started, which drives the gear 2 fixedly connected to it to rotate. Since the gear 2 meshes with the gear 1 on the cleaning brush 14, the drive motor 13 drives the cleaning brush 14 to rotate in a ring, thereby cleaning the filter screen 3.

[0028] Please see Figure 1 As shown, a maintenance port 9 is provided on one side of the feed pipe 2, a protective cover 10 is provided on the maintenance port 9, and a maintenance ladder 11 is installed on the outer wall of the tank body 1.

[0029] In this embodiment, the inspection port 9 allows for the maintenance of the tank 1, and the maintenance ladder 11 facilitates the replacement of the filter screen 3 by the staff.

[0030] Please see Figure 1-2As shown, the bottom of the tank body 1 is further provided with support legs 12.

[0031] In this embodiment, the support leg 12 serves a supporting function.

[0032] Please see Figure 4 As shown, further, the bottom end of the card plate 4 is arranged in a decreasing manner from top to bottom, and one side of the card plate 4 is arranged in a increasing manner from left to right.

[0033] In this embodiment, it is convenient to install and remove the filter screen 3.

[0034] Furthermore, the inner surface of tank 1 is coated with an anti-corrosion layer.

[0035] In this embodiment, corrosion is prevented, thus extending the service life.

[0036] Furthermore, the tank body 1, feed pipe 2, clamping plate 4, protective cover 10, maintenance ladder 11 and support leg 12 are all made of metal materials.

[0037] In this embodiment, the tank body 1, feed pipe 2, clamping plate 4, protective cover 10, maintenance ladder 11 and support leg 12 are all made of aluminum alloy.

[0038] The working principle of this utility model:

[0039] The filter screen 3 is installed and removed using the installation mechanism. When installing the filter screen 3, first place the filter screen 3 under the installation mechanism, push the filter screen 3 to move it upward. Under the upward force of the filter screen 3, the spring 5 and the rubber column 6 are compressed, and the clamping plate 4 is stored inside the opening. When the clamping plate 4 is at the same horizontal line as the groove 8 on the filter screen 3, the clamping plate 4 extends into the groove 8 under the action of the spring 5 and the rubber column 6, thereby fixing the filter screen 3. When removing the filter screen 3, rotate the filter screen 3 so that the clamping plate 4 extends into the opening under the action of the spring 5 and the rubber column 6, and then the clamping plate 4 can be taken out. The installation and removal operations are convenient.

[0040] After prolonged use, the filter screen 3 can be cleaned through the cleaning mechanism to prevent clogging. Start the drive motor 13 to drive the gear two fixedly connected to it to rotate. Since gear two meshes with gear one on the cleaning brush 14, the drive motor 13 drives the cleaning brush 14 to rotate in a ring, thereby cleaning the filter screen 3.

[0041] This invention reduces equipment downtime, thereby improving equipment operating and maintenance efficiency. Installing and disassembling the filter screen becomes more convenient, significantly reducing the operational difficulty and time costs for professional technicians. It also avoids production losses caused by frequent equipment downtime. The cleaning mechanism effectively removes impurities from the filter screen, reducing malfunctions caused by clogging, thus reducing labor and material costs required for equipment maintenance. Regularly cleaning the filter screen effectively prevents the accumulation of pollutants and dirt, reducing damage to the filter screen and other equipment components. Timely cleaning of the filter screen through the cleaning mechanism prevents clogging and damage, extending the lifespan of the filter screen. The extended lifespan of the evaporator reduces the frequency of equipment replacement. The cleanliness of the filter directly impacts wastewater treatment efficiency. Regularly cleaning the filter and keeping it clear ensures smooth wastewater flow, thereby improving the stability and efficiency of the evaporation and concentration process. This guarantees the continuous and efficient operation of the wastewater MVR treatment system, achieving the expected wastewater treatment results. The design of the installation and cleaning mechanisms ensures that the filter remains in good condition during long-term operation of the wastewater MVR evaporator, reducing system pressure fluctuations and thermal efficiency decline caused by clogging. This optimizes the overall system's thermal energy utilization efficiency, further enhancing the system's economy and environmental friendliness.
