Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, and specifically to an anti-clogging structure for evaporators. Background Technology

[0002] With the widespread application of evaporation equipment in industrial production, evaporators have been continuously promoted in food processing, chemical, pharmaceutical, and wastewater treatment fields. During long-term operation, evaporators require evaporation filters to remove impurities from incoming gases or liquids to ensure evaporation efficiency and equipment stability. As application demands continue to increase, evaporators handling high-concentration, high-impurity materials place higher demands on the permeability and cleanliness of the filters. Therefore, technologies related to preventing filter clogging are gradually gaining importance.

[0003] In existing technologies, to avoid clogging of the evaporator filter, an evaporator base is typically installed below the evaporator cylinder, with a filter screen placed inside the base, supplemented by mechanical cleaning methods to remove impurities. For example, some solutions use fixed scrapers to clean impurities; however, because the scraping position is fixed, it is often impossible to thoroughly clean the upper and lower surfaces of the filter screen and the inner wall of the evaporator base, easily leading to incomplete cleaning in certain areas. As operating time increases, deposits will gradually accumulate on the edges of the filter screen and the inner wall of the evaporator base, resulting in decreased filtration efficiency and even an increased risk of clogging.

[0004] In view of the above, in order to overcome the above technical problems, this utility model designs an anti-clogging structure for an evaporator, thus solving the above technical problems. Summary of the Invention

[0005] The technical objective of this invention is to provide an anti-clogging structure for an evaporator, which can effectively clean the evaporator filter and the inner wall of the evaporator base, thereby reducing the risk of filter clogging and ensuring long-term stable operation of the evaporator.

[0006] To achieve the above-mentioned technical objectives, this utility model provides the following technical solution: The present invention provides an anti-clogging structure for an evaporator located below the evaporator cylinder. An evaporator base is installed below the evaporator cylinder, and an air inlet is provided on the evaporator base. The anti-clogging structure is installed on an evaporator filter screen inside the evaporator base. The evaporator filter screen is located at the center of the evaporator base, and an anti-clogging gap is provided between the side of the evaporator filter screen and the inner wall of the evaporator base.

[0007] This utility model provides an anti-clogging structure for an evaporator, comprising a drive motor, a transmission rod, an anti-clogging scraper, and a jet nozzle. The drive motor is installed at the bottom of the evaporator base and is used to drive the anti-clogging structure. The transmission rod is connected to the output shaft of the drive motor and is used to drive the upper component thereon to rotate around the evaporator filter. The anti-clogging scraper is installed on the transmission rod and is in contact with the lower surface of the evaporator filter to scrape off impurities from the lower surface of the evaporator filter. The jet nozzle is installed at the end of the transmission rod and is located within the anti-clogging interval to spray air to remove impurities from the upper surface of the evaporator filter and the inner wall of the evaporator base.

[0008] The jet nozzle includes a filter nozzle and an inner wall nozzle. The filter nozzle passes upward through the anti-clogging gap and is aligned with the upper surface of the evaporation filter. The inner wall nozzle passes downward through the anti-clogging gap and is aligned with the interior of the evaporation seat near the bottom.

[0009] Furthermore, the filter nozzle is provided with an anti-clogging jet surface at an angle, and the anti-clogging jet surface is at a 50-70 degree angle to the upper surface of the evaporation filter.

[0010] Furthermore, the inner wall nozzle is provided with an inclined jet surface that promotes airflow, and the jet surface is at an angle of 30-50 degrees to the inner wall of the evaporator.

[0011] Preferably, the anti-clogging scraper is made of hard rubber.

[0012] More preferably, the length of the anti-clogging scraper is not less than the diameter of the evaporation filter.

[0013] The inner wall of the evaporator is provided with guide protrusions, which are regular polygons or circles.

[0014] The anti-clogging interval is provided with a flow guide block above it. The flow guide block is installed on the inner wall of the evaporator seat and is used to guide the material to fall onto the evaporator filter screen.

[0015] The beneficial effects of this utility model are as follows: 1. This application uses a drive motor to rotate a transmission rod, which causes the anti-clogging scraper to scrape the lower surface of the evaporator filter. At the same time, the jet nozzle sprays air onto the upper surface of the evaporator filter and the inner wall of the evaporator seat to remove impurities. This forms a synergistic effect of mechanical cleaning and gas flushing, thereby achieving dynamic cleaning of the evaporator filter and surrounding deposits, effectively preventing filter clogging, and ensuring the permeability and stability of the evaporator during long-term operation.

[0016] 2. The jet nozzle of this application includes a filter screen nozzle and an inner wall nozzle. The filter screen nozzle is provided with an anti-clogging jet surface and is directed at the upper surface of the filter screen at an inclined angle to flush it with airflow. This causes impurities to be removed from the filter screen pores under the impact of the airflow and carried away in time, thereby improving the cleaning range and flushing effect, and further improving the filtration efficiency and service life of the filter screen.

[0017] 3. This application provides flow guide protrusions or flow guide blocks on the inner wall of the evaporator, which, together with the flow-promoting jet surface of the inner wall nozzle, generate turbulent airflow, so that the material can fall evenly on the evaporation filter and reduce its accumulation on the inner wall. This not only improves the flow field distribution but also reduces the possibility of local deposit formation, thereby further reducing the maintenance frequency and improving the continuity of equipment operation.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] Example 1: This example provides an anti-clogging structure for an evaporator, which is located below the evaporator cylinder 1. An evaporator base 2 is fixedly installed below the evaporator cylinder 1, and an air inlet 3 is provided on the evaporator base 2 for the entry of external gas. An evaporator filter 4 is provided inside the evaporator base 2 and is fixed at the center of the evaporator base 2. An anti-clogging gap 21 is formed between the outer periphery of the evaporator filter 4 and the inner wall of the evaporator base 2 to provide space for subsequent air jetting and cleaning.

[0023] In this embodiment, the anti-clogging structure has a drive motor 5 installed at the bottom of the evaporator base 2. The output shaft of the drive motor 5 is connected to a transmission rod 6, which is horizontally arranged along the center of the evaporator base 2 and rotates around the evaporator filter 4 under the drive of the drive motor 5. An anti-clogging scraper 7 is installed on the upper part of the transmission rod 6. The upper part of the anti-clogging scraper 7 is arranged in close contact with the lower surface of the evaporator filter 4, and mechanically scrapes away the deposits on the filter screen as the rod rotates.

[0024] Meanwhile, an air jet head 8 is provided at the end of the transmission rod 6. The air jet head 8 is located within the anti-clogging interval 21. During operation, it can spray air to clean the upper surface of the evaporation filter screen 4 and the inner wall of the evaporation seat 2, making it difficult for impurities to accumulate and clog.

[0025] Example 2: Based on Example 1, further optimization is made. The jet head 8 specifically includes a filter nozzle 81 and an inner wall nozzle 82. The filter nozzle 81 extends above the transmission rod 6 and passes through the anti-clogging interval 21. Its jet direction is towards the upper surface of the evaporation filter 4. In this example, the angle between the jet nozzle and the filter surface is 60°. The anti-clogging jet surface 811, set by this inclined angle, can make the jet airflow impact the surface of the evaporation filter 4 and diffuse along the plane of the evaporation filter 4, effectively blowing away the fine particles deposited on the filter, thereby improving the cleaning effect.

[0026] In this embodiment, the inner wall nozzle 82 extends downward along the transmission rod 6 and passes through the anti-clogging interval 21. The nozzle faces the inner wall of the evaporator 2 near the bottom. In this embodiment, the angle between the nozzle and the inner wall of the evaporator 2 is 40°. Through this inclined flow-promoting jet surface 821, the jet airflow can generate a wall-adhering flow along the inner wall of the evaporator 2, which can both blow away impurities attached to the inner wall and form a circulation effect, avoiding the deposition and accumulation of materials in the bottom area of ​​the inner wall.

[0027] Example 3: Based on Examples 1 and 2, the anti-clogging structure can be further optimized. The anti-clogging scraper 7 is made of hard rubber material to ensure sufficient scraping strength when scraping deposits on the lower surface of the filter screen, while avoiding damage to the filter screen. In specific implementation, the length of the anti-clogging scraper 7 is designed to be equal to the diameter of the evaporation filter screen 4, ensuring that the scraper can cover the entire span of the filter screen when rotating, thereby achieving comprehensive cleaning.

[0028] To further improve the flow field distribution, guide protrusions 23 are provided on the inner wall of the evaporator seat 2. The guide protrusions 23 are hexagonal in shape, and their arrangement can create disturbance when the airflow passes through, so that the material falls more evenly on the filter screen and reduces the deposition on the inner wall. In addition, a guide block 22 is installed above the anti-clogging interval 21. The guide block 22 is fixed to the inner wall of the evaporator seat 2 and has an arc-shaped cross-section. It can guide the material flow entering the evaporator seat 2 to the central area of ​​the evaporation filter screen 4, avoiding the material from directly impacting the inner wall and causing uneven distribution, thereby further improving the overall anti-clogging performance and operational stability of the evaporator.
