Description

Technical Field

[0001] This utility model relates to the technical field of electrostatic precipitators, and in particular to the technical field of electrostatic precipitator ash hoppers. Background Technology

[0002] An electrostatic precipitator is a dust removal device that uses electrostatic force to separate dust or liquid droplets from a gas. It is also known as an electrostatic dust collector or electrostatic precipitator. Electrostatic precipitators are widely used in industries such as metallurgy, cement, gas, power plant boilers, sulfuric acid, and papermaking.

[0003] Dust discharged from an electrostatic precipitator is collected in a dust hopper. Existing technologies typically install a vibrator on the outside of the dust hopper to help the dust discharge, but the vibration effect of the vibrator is limited. Patent document CN212633039U discloses a dust hopper for an electrostatic precipitator. This dust hopper discharges dust from the hopper by installing a screw at the bottom of the hopper. However, when the dust above the screw accumulates into clumps, blockage can easily occur, affecting the discharge. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems in the prior art by proposing an electrostatic precipitator ash hopper that can solve the above problems.

[0005] To achieve the above objectives, this utility model proposes an electrostatic precipitator ash hopper, comprising an ash hopper body, an ash discharge pipe at the bottom of the ash hopper body, a rotating shaft rotatably mounted inside the ash hopper body, loosening screws on both sides of the rotating shaft, the loosening screws on both sides being symmetrically arranged, a discharge shaft rotatably mounted inside the ash discharge pipe, a discharge screw on the discharge shaft, a first bevel gear at the top of the discharge shaft, a second bevel gear on the rotating shaft, the first bevel gear and the second bevel gear being meshed together, and a rotating motor connected to the rotating shaft.

[0006] Preferably, the discharge shaft is located on the central axis of the ash discharge pipe.

[0007] Preferably, the ash hopper body is provided with a gearbox, in which the first bevel gear and the second bevel gear are both installed, and the top of the gearbox is provided with a conical cover.

[0008] Preferably, the ash hopper body is provided with a mounting bracket, the discharge shaft is rotatably mounted on the mounting bracket, and the mounting bracket is connected to the ash hopper body through several connecting rods.

[0009] The beneficial effects of this utility model are as follows: By setting a loosening screw in the ash hopper body and a discharge screw in the ash discharge pipe, the accumulated ash is first loosened above the ash discharge pipe, and then the dust is discharged through the discharge screw, thus avoiding ash blockage; the conical cover of the gearbox can prevent dust from accumulating on the top of the gearbox.

[0010] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0014] See Figure 1 , Figure 2 An electrostatic precipitator ash hopper includes an ash hopper body 1, an ash discharge pipe 2 at the bottom of the ash hopper body 1, a rotating shaft 3 rotatably installed inside the ash hopper body 1, loosening screws 4 on both sides of the rotating shaft 3, the loosening screws 4 on both sides being symmetrically arranged, a discharge shaft 5 rotatably installed inside the ash discharge pipe 2, a discharge screw 6 on the discharge shaft 5, a first bevel gear 7 on the top of the discharge shaft 5, a second bevel gear 8 on the rotating shaft 3, the first bevel gear 7 and the second bevel gear 8 being meshed together, and a rotating motor 9 connected to the rotating shaft 3.

[0015] The electrostatic precipitator has multiple hoppers arranged in parallel, and the rotating shafts of adjacent hoppers are connected by couplings. Multiple rotating shafts can be driven by a single motor to discharge materials simultaneously.

[0016] The discharge shaft 5 is located on the central axis of the ash discharge pipe 2.

[0017] The ash hopper body 1 is provided with a gearbox 10, and the first bevel gear 7 and the second bevel gear 8 are both installed in the gearbox 10. The top of the gearbox 10 is provided with a conical cover 11.

[0018] The ash hopper body 1 is provided with an installation bracket 12, and the discharge shaft 5 is rotatably installed on the installation bracket 12. The installation bracket 12 is connected to the ash hopper body 1 through several connecting rods 13.

[0019] The connecting rod is tilted downwards to allow the dust to be discharged smoothly downwards.

[0020] When the moisture content in the flue gas is too high, the dust easily absorbs moisture and becomes damp, increasing its stickiness and causing it to clump and clog in the ash hopper. This invention uses a loosening screw, combined with an ash hopper heating device, to loosen the clumped dust and then discharge it through a discharge screw, thus avoiding ash blockage.

[0021] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
