[0001] The utility model relates to the field of electrostatic dust removal, in particular to a wet high-voltage electrostatic dust collector with a wall scraping mechanism. Background Art

[0002] A wet high-voltage electrostatic precipitator is a device used to remove particulate matter from flue gas, while a wet high-voltage electrostatic precipitator with a scraping wall mechanism adds a scraping wall mechanism to the traditional wet high-voltage electrostatic precipitator to further improve the dust removal efficiency and performance.

[0003] When the existing equipment scrapes the inner wall of the dust box, the scraper plate is in wear contact with the side wall of the dust box for a long time, and the scraping end is easily severely worn. The severely worn scraper plate cannot fit in contact with the inner wall of the dust box, and it is necessary to manually adjust the contact distance between the scraper plate and the inner wall of the dust box many times, which is time-consuming. Utility Model Content

[0004] The main purpose of the utility model is to provide a wet high-voltage electrostatic precipitator with a wall scraping mechanism, which can effectively solve the technical problems in the background technology.

[0007] As a further solution of the utility model, a cleaning structure is provided at the upper end of the two groups of scraper plates, and the cleaning structure includes a chassis, a motor is installed at the front end of the chassis, a screw rod is installed inside the chassis after the output end of the motor enters, a slider is provided on the outer wall thread of the screw rod, and a cleaning brush is provided at one end of the slider.

[0008] As a further solution of the utility model, the front and rear ends of the scraping frame are both provided with stabilizing grooves, and the front and rear ends of the sliding plate respectively enter the interiors of the two groups of stabilizing grooves.

[0009] As a further solution of the utility model, guide rods are installed at the front and rear ends of one side of the scraper plate, and one end of the guide rod is located inside the sliding plate to slide.

[0010] As a further solution of the utility model, a fixing frame is fixedly provided on the inner wall of the scraping frame, and an internal thread of the fixing frame is provided with a screw rod, and one end of the screw rod is rotatably connected to the sliding plate.

[0011] As a further solution of the utility model, a bracket is fixedly provided at the lower end of the dust removal box.

[0012] The beneficial effects of the utility model are as follows:

[0013] By setting up the extrusion structure, when the scraper plate is frequently scraped against the inner wall of the dust box and is severely worn, the reset ability of the push spring makes one end of the scraper plate automatically push toward the side wall of the dust box. When the scraper plate is severely worn, no manual adjustment is required to achieve better fit.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-5As shown, a wet high-voltage electrostatic precipitator with a wall scraping mechanism includes a dust removal box 1 and an upper cover 2. A cylinder 4 is arranged at the upper end of the upper cover 2. The output end of the cylinder 4 enters the dust removal box 1 and is connected to a scraping frame 5. Auxiliary plates 15 are installed at the front and rear ends of the scraping frame 5. An air inlet pipe 3 is arranged on one side of the dust removal box 1. Extrusion structures 6 are arranged on both sides of the scraping frame 5. The extrusion structure 6 includes scraping plates 7. Slide grooves 8 are opened on both sides of the scraping frame 5. A sliding plate 9 is arranged on the inner wall of the scraping frame 5. A push spring 10 is installed between the sliding plate 9 and the scraping plate 7.

[0023] In this embodiment, a cleaning structure 16 is provided at the upper end of the two groups of scraper plates 7. The cleaning structure 16 includes a chassis 17. A motor 19 is installed at the front end of the chassis 17. The output end of the motor 19 enters the chassis 17 and a screw rod 18 is installed inside the chassis 17. The outer wall of the screw rod 18 is threaded with a slider 20, and a cleaning brush 21 is provided at one end of the slider 20.

[0024] The chassis 17 is used to set a motor 19, and the motor 19 is used to drive the screw rod 18 to rotate. The screw rod 18 is used to drive the slider 20 to drive the cleaning brush 21 to move, and the cleaning brush 21 performs secondary cleaning on the area scraped by the scraper plate 7.

[0025] In this embodiment, the front and rear ends of the scraping frame 5 are both provided with stabilizing grooves 12 , and the front and rear ends of the sliding plate 9 enter into the two sets of stabilizing grooves 12 respectively.

[0026] The stabilizing groove 12 is used to facilitate the smooth movement of the sliding plate 9 .

[0027] In this embodiment, guide rods 11 are installed at the front and rear ends of one side of the scraper plate 7 , and one end of the guide rod 11 is located inside the sliding plate 9 for sliding.

[0028] The guide rod 11 ensures the smooth movement of the scraper plate 7.

[0029] In this embodiment, a fixing frame 13 is fixedly provided on the inner wall of the scraping frame 5 , and a screw rod 14 is provided on the internal thread of the fixing frame 13 , and one end of the screw rod 14 is rotatably connected to the sliding plate 9 .
