Description

Technical Field

[0001] The invention belongs to the technical field of electrostatic precipitators, and in particular relates to an automatic cleaning device for dust accumulation at an ash hopper joint of an electrostatic precipitator. Background Art

[0002] The working principle of an electrostatic precipitator is that as flue gas passes through the flue duct in front of the main structure of the electrostatic precipitator, it becomes positively charged. The flue gas then enters the electrostatic precipitator channel, which is equipped with multiple layers of cathode plates. Due to the mutual attraction between the positively charged dust and the cathode plates, particles in the flue gas are attracted to the cathodes. Timed impacts on the cathode plates cause dust particles of a certain thickness to fall into the ash hopper below the electrostatic precipitator structure due to the combined effects of their own weight and vibration, thus removing dust from the flue gas.

[0003] After the existing multi-ash hopper electrostatic precipitator has been running for a period of time, the collected dust falls into the ash hopper under the action of vibration, and is prone to accumulation at the ash hopper joint. As the operation time goes by, when the dust accumulates to the cathode, it causes the problem of electric field failure. For this reason, we propose an automatic cleaning device for the dust accumulation at the ash hopper joint of the electrostatic precipitator. Summary of the Invention

[0032] Example 2:

[0033] See also Figures 1 to 7 As shown, based on the first embodiment, the present invention provides a technical solution: the transmission mechanism 13 includes a driving disc 15 fixed to one end of the vibration shaft 14, a rotating disc 17 fixed to one end of the toggle rod 11, and a transmission disc 16 rotatably mounted on one end of the ash hopper beam 9.

The driving disc 15, the transmission disc 16, and the rotating disc 17 are connected by the transmission rod 18. The vibration shaft 14 drives the driving disc 15 to rotate, and the driving disc 16 is driven. The movable plate 15 drives the transmission plate 16 to rotate through the transmission rod 18, and the transmission plate 16 drives the rotating plate 17 and the toggle rod 11 to rotate through the transmission rod 18. When the toggle rod 11 rotates, the toggle piece 12 is driven to scrape off the dust on the ash hopper beam 9; the transmission rods 18 are equidistantly arranged on the driving plate 15, the transmission plate 16 and the rotating plate 17, and the position and size of the transmission rods 18 on the driving plate 15, the transmission plate 16 and the rotating plate 17 are the same, which makes the transmission between the driving plate 15, the transmission plate 16 and the rotating plate 17 more convenient.

[0034] When using the above-mentioned transmission mechanism 13, it is necessary to clean the dust by driving the toggle rod 11 during use. When in use, the driving disk 15 is driven to rotate by the vibration shaft 14, and the rotating disk 17 and the toggle rod 11 are driven to rotate by the transmission disk 16 and the transmission rod 18. Therefore, it is more convenient when driving the toggle rod 11 to rotate without other equipment.

[0035] Further, see Figure 2 and Figure 5The mounting seat 10 includes a bracket 20, which is fixed on the ash hopper beam 9. The upper end of the bracket 20 is rotatably connected to a fixed buckle plate 19 through a rotating shaft. A bearing is engaged with the inner side of the fixed buckle plate 19 and the bracket 20, and the toggle rod 11 is installed between the fixed buckle plate 19 and the bracket 20 through a bearing. One end of the fixed buckle plate 19 is fixedly connected to the bracket 20 through a fixed buckle 23. Just open the fixed buckle 23 and then flip open the fixed buckle plate 19, and then the toggle rod 11 can be removed from the bracket 20, which is more convenient and quick when disassembling. A card block 22 is provided at one end of the fixed buckle plate 19, and a card slot 21 is provided on the upper side of the bracket 20 corresponding to the position of the card block 22.

[0036] When using the above-mentioned mounting base 10, the toggle rod 11 is installed on the bracket 20 during use, and the mounting base 10 can be disassembled and assembled by flipping open the fixed buckle plate 19, which makes it more convenient and quick to disassemble and replace the mounting base 10.

[0037] The working principle and use process of the present invention are as follows: when in use, the dust removal box 1 is energized through the anode plate 4 and the cathode frame 5 to absorb the dust and the like in the flue gas, and at the same time, the vibration motor 31 drives the vibration shaft 14 to rotate, and the vibration shaft 14 drives the eccentric wheel 32 to rotate, so that the eccentric wheel 32 pushes the vibration seat 33 and the vibration frame 27 to shake, so that the vibration spring 30 and the vibration clamping plate 29 inside the vibration frame 27 vibrate and clean the dust on the surface of the anode plate 4. When the dust falls into the ash hopper 2, it will accumulate on the ash hopper beam 9 at the connection of the ash hopper 2 and is difficult to clean. It only needs to be cleaned by the anode vibration. The vibration shaft 14 of the beating mechanism drives the driving disc 15 to rotate, and the driving disc 15 drives the transmission disc 16 to rotate through the transmission rod 18, and the transmission disc 16 drives the rotating disc 17 and the toggle rod 11 to rotate through the transmission rod 18. When the toggle rod 11 rotates, it drives the toggle piece 12 to scrape off the dust on the ash hopper beam 9 to prevent dust accumulation from touching the cathode, causing electric field failure, and causing the toggle rod 11 to malfunction during use. When disassembly is required, just open the fixing buckle 23 and then flip open the fixing buckle plate 19, and then the toggle rod 11 can be removed from the bracket 20, which is more convenient and quick when disassembling.
