Description

Technical Field

[0001] The utility model belongs to the technical field of material processing equipment, and in particular relates to a drawer-type dust collecting hopper for a pulse purification dust collector. Technical Background

[0002] The function of the pulse purification dust collector is that when the dust-laden gas enters the dust filter bag, the dust with large particles and high specific gravity settles down due to gravity and falls into the ash hopper. When the gas containing finer dust passes through the dust filter bag, the dust is retained, so that the gas is purified. Then the dust adhering to the outside of the dust filter bag is discharged by pulse blowing, and the dust material falls into the dust hopper. The pulse purification dust collector has the characteristics of strong cleaning ability, high dust removal efficiency, low emission concentration, low air leakage rate, low energy consumption, small footprint, and reliable and stable operation.

[0003] However, the existing pulse purification dust collector is respectively provided with a dust box, a pulse chamber, and a motor chamber from bottom to top, wherein the pulse chamber and the motor chamber are connected by a first partition, and the pulse chamber and the dust box are connected by a second partition, wherein one or more through holes are provided in the second partition, and dust filter bags are provided corresponding to the through holes. Then a pulse dust removal working component is provided in the pulse chamber, wherein the pulse dust removal working component mainly includes an injection pipe and a pulse valve, wherein the injection pipe removes dust from the dust filter bag through the through hole, and a motor assembly is provided in the motor chamber. The existing pulse purification dust collector directly uses the dust box as a dust hopper, i.e., dust is collected in the dust box, and a dust filter bag is also provided in the dust box. On the one hand, if the dust box is not handled in time, it will be filled with dust, causing the dust collector to be unable to operate. On the other hand, it also causes the dust to be difficult to clean, such as the dust falling on the rear side of the dust filter bag is difficult to clean, etc., thus reducing the dust removal efficiency of the dust collector. Utility Model Content

[0004] In order to solve the technical problems in the prior art, the utility model provides a drawer-type dust hopper for the existing pulse purification dust collector, and is implemented through the following technical solutions:

[0005] A drawer-type dust hopper for a pulse purification dust collector comprises a pulse purification dust collector, wherein a dust box is provided at the lower part of the pulse purification dust collector, a plurality of dust filter bags are provided in the dust box, and air inlets for conveying dust by airflow are provided on both sides of the dust box near the bottom, a drawer-type dust hopper is provided under the dust box, and a square or rectangular through hole is provided on the bottom plate of the dust box, and the drawer-type dust hopper is connected with the dust box through the through hole; the size of the through hole is smaller than that of the drawer-type dust hopper, and an inclined material guiding structure is circumferentially provided along the outer edge of the through hole, so that the dust in the dust box falls into the drawer-type dust hopper.

[0006] In an embodiment, the drawer-type dust hopper is mainly composed of a drawer chamber and a dust drawer, and the dust drawer is embedded in the drawer chamber through a port of the drawer chamber. The dust drawer includes an outer plate, and a sealing ring is circumferentially provided on the inner side of the outer plate facing the drawer port, so that the dust drawer is sealed and connected to the drawer port, and preferably a silicone rubber sealing ring.

[0007] In an embodiment, a pulley assembly consisting of a plurality of pulleys is provided at both sides of the bottom of the dust collection drawer, and a slide rail corresponding to the pulley assembly is provided at both sides of the bottom of the drawer chamber, and the dust collection drawer is connected to a track through the pulley assembly and the slide rail.

[0008] In addition, a handle is provided on the outside of the outer side panel.

[0009] The beneficial effects achieved by the utility model are as follows: the utility model arranges a drawer-type dust hopper under the dust box, so that the dust falls directly into the drawer-type dust hopper through the inclined material guiding structure. At the same time, the inclined material guiding structure is arranged to prevent dust from being scattered on both sides of the drawer, hindering the pulling and drawing of the dust drawer, and especially affecting the sliding of the pulley assembly / slide rail.

[0010] The drawer-type dust hopper is convenient for collecting and transporting dust, improves the efficiency of dust treatment, and avoids the situation where the dust box is filled with dust due to untimely treatment, causing the dust collector to fail to operate.
