[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0023] Reference Figures 1-4 An MVR evaporator designed to prevent dust accumulation includes an evaporator body 3 with multiple heat sinks 9 mounted on its side. The evaporator body 3 includes a filtration system, a preheating system, a plate heater, a material pump, a separator, and a steam compressor.

[0024] A mounting bracket 1 is bolted to one side of the outer wall of the evaporator body 3. A threaded rod 11 is rotatably connected to the top of the mounting bracket 1. A power component that drives the threaded rod 11 to rotate is provided on the upper surface of the mounting bracket 1. The power component includes a motor. The motor is bolted to the upper surface of the mounting bracket 1, and one end of the motor output shaft passes through the top plate of the mounting bracket 1 and is fixed to the threaded rod 11. A slider 12 is threaded to the outer side of the threaded rod 11. A rotating shaft 4 is rotatably connected to one side of the slider 12. A scraper 2 is bolted to one side of the rotating shaft 4. The scraper 2 has multiple scraping blades. Each scraping blade is located between two heat sinks 9, and the scraping blades are in contact with both surfaces of the heat sinks 9. The power component causes the threaded rod 11 to drive the slider 12 to move downward, thereby causing the rotating shaft 4 to drive the scraper 2 to move downward to clean the heat sinks 9.

[0025] Two support frames 7 are bolted to one side of the outer wall of the evaporator body 3. Multiple first racks 6 and multiple second racks 20 are bolted to the inner walls of both sides of the support frames 7, and the first racks 6 and second racks 20 are spaced apart. Gears 5 are keyed to both ends of the rotating shaft 4, and the gears 5 can mesh with the second racks 20 and the first racks 6. At the same time, the rotating shaft 4 moves downward, causing the gears 5 to move downward. Under the action of the second racks 20, the gears 5 rotate, thereby causing the rotating shaft 4 to drive the scraper 2 to rotate. Then the rotating shaft 4 continues to move downward, causing the gears 5 to separate from the second racks 20 and mesh with the first racks 6 at the bottom adjacent position. Thus, while the gears 5 move downward, under the action of the first racks 6, the rotating shaft 4 drives the scraper 2 to rotate in the opposite direction. This cycle is repeated, so that the scraper 2 swings up and down to clean the dust on the heat sink 9.

[0026] A collection box 8 is installed on the bottom inner wall of the fixed frame 1 via a guide assembly. The collection box 8 collects the cleaned dust for centralized processing by staff. The guide assembly includes two slots 18, which are located on the bottom inner wall of the fixed frame 1. Two positioning strips 17 are fixed to the bottom outer wall of the collection box 8 by bolts, and the positioning strips 17 are slidably connected to the corresponding slots 18. The guide assembly enables the collection box 8 to move stably.

[0027] In this utility model, it should be noted that the bottom of the fixing frame 1 is provided with a pin assembly for fixing the position of the collection box 8. The pin assembly includes a fixing plate 16, which is fixed to the outer wall of one side of the fixing frame 1 by bolts. The fixing plate 16 is internally threaded with a screw rod 15, and one end of the screw rod 15 is fixed with a protrusion 14 by bolts. A groove 13 is provided on one side of the outer wall of the collection box 8, and the protrusion 14 is inserted into the groove 13. Through the cooperation of the protrusion 14 and the groove 13, the position of the collection box 8 is limited and fixed. A connecting plate 19 is fixed to one side of the inner wall of the fixing frame 1 by bolts. When it is necessary to clean the dust in the collection box 8, the screw rod 15 is rotated to move the protrusion 14 out of the groove 13. At this time, the collection box 8 is no longer restricted. The staff pulls the collection box 8 so that the positioning strip 17 slides along the slot 18 to the required position, which facilitates the staff to clean the impurities in the collection box 8.

[0028] A guide rod 10 is bolted between the connecting plate 19 and the top of the fixed frame 1, and the guide rod 10 is slidably connected to the slider 12. The guide rod 10 can guide the slider 12 so that it can move stably. The bottom end of the threaded rod 11 is rotatably connected to the connecting plate 19.

[0029] Working principle: When it is necessary to clean the dust on the heat sink 9, the motor is first started. The motor rotation causes the threaded rod 11 to drive the slider 12 to move downward along the guide rod 10, thereby causing the rotating shaft 4 to drive the scraper 2 to move downward. At the same time, the downward movement of the rotating shaft 4 causes the gear 5 to move downward. Under the action of the second rack 20, the gear 5 rotates, thereby causing the rotating shaft 4 to drive the scraper 2 to rotate. Then, the rotating shaft 4 continues to move downward, causing the gear 5 to disengage from its meshing with the second rack 20 and mesh with the first rack 6 at the adjacent position at the bottom, thus causing the gear 5 to move downward while simultaneously... Under the action of the first rack 6, the rotating shaft 4 drives the scraper 2 to rotate in the opposite direction. This cycle repeats, causing the scraper 2 to swing up and down to clean the dust on the heat sink 9. The cleaned dust falls into the collection box 8. The motor reverses, and the slider 12 rises to perform a second scraping. When it is necessary to clean the dust in the collection box 8, the lead screw 15 is rotated to move the protrusion 14 out of the groove 13. At this time, the collection box 8 is no longer restricted. The staff pulls the collection box 8 so that the positioning strip 17 slides along the slot 18 to the required position, which makes it easier for the staff to clean the impurities in the collection box 8.
