Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, and particularly relates to a biomass fuel non-powered dust removal and material guiding trough device. Background Art

[0002] A non-powered dust removal and material guiding trough is a device that combines material guiding and dust removal functions during the material transportation process. It combines the longitudinal flow of materials in the trough and the forced discharge of the dust removal and discharge mechanism through a reasonable structural design and fluid mechanics principle, achieving effective material diversion and dust removal treatment;

[0003] During the material transportation process, the non-powered dust removal and material guiding trough can effectively remove particulate matter and accurately guide the material to the destination. For example, the Chinese utility model patent with the publication number CN219057634U: a non-powered dust removal device for a conveyor belt. This application realizes double-layer sealing at the connection between the conveyor belt and the material guiding trough by setting an arc plate and a sliding plate, thereby effectively preventing dust from entering the connection between the conveyor belt and the material guiding trough. First, the arc edge and the sliding plate in this application are in direct contact with the conveyor belt, and the conveyor belt will continuously rub against the arc plate and the sliding plate during operation, which will reduce the service life of the conveyor belt. Second, the conveyor will shift to a certain extent during operation, and the arc plate and the sliding plate are fixed to one side of the side plate through an inclined plate. Therefore, it is impossible to ensure that the arc edge and the sliding plate are always in contact with the conveyor belt. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a biomass fuel non-powered dust removal and material guiding trough device, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A biomass fuel non-powered dust removal and material guiding trough device includes a dust removal bin. A plurality of dust settling curtains are fixedly installed in the dust removal bin. A plurality of first fixing pipes and second fixing pipes are also fixedly installed at the upper end of the dust removal bin. And a single first fixing pipe and a single second fixing pipe form a group. A circulation pipe is fixedly connected between the first fixing pipe and the second fixing pipe. A dust settling curtain box is also fixedly installed on the dust removal bin on one side of the first fixing pipe. A feeding pipe is fixedly installed on one side of the upper end of the dust removal bin. A plurality of first sealing plates are movably installed at the lower end of the dust removal bin.

[0007] As a further preferred solution of the utility model, the outside of the dust removal bin is fixedly installed on the conveyor belt through a bracket.

[0008] As a further preferred solution of the utility model, telescopic grooves are opened on both sides inside the dust removal bin. Opening telescopic grooves on both sides inside the dust removal bin can realize the up and down displacement function of the first sealing plate.

[0009] As a further preferred embodiment of the present utility model, a plurality of first fixing seats are fixedly installed on the outer side of the dust removal bin, and connecting bolts are inserted and installed in the first fixing seats.

Specific implementation manners

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0021] As Figures 1-4 shown, a biomass fuel non-powered dust removal and material guiding trough device provided by the present utility model includes a dust removal bin 1, in which a plurality of dust reduction curtains 2 are fixedly installed, and a plurality of first fixed pipes 3 and second fixed pipes 4 are also fixedly installed at the upper end of the dust removal bin 1. And a single first fixed pipe 3 and a single second fixed pipe 4 are a group. A circulation pipe 5 is fixedly connected between the first fixed pipe 3 and the second fixed pipe 4. A dust reduction curtain box 6 is also fixedly installed on the dust removal bin 1 on one side of the first fixed pipe 3. A blanking pipe 7 is fixedly installed on one side of the upper end of the dust removal bin 1. A plurality of first sealing plates 8 are movably installed at the lower end of the dust removal bin 1.

[0022] As Figure 1 shown, the outside of the dust removal bin 1 is fixedly installed on the conveyor belt through a bracket;

[0023] As Figures 1-2 shown, telescopic grooves 9 are opened on both sides inside the dust removal bin 1. By opening telescopic grooves 9 on both sides inside the dust removal bin 1, an up-and-down displacement function of the first sealing plate 8 can be realized. A plurality of first fixed seats 10 are fixedly installed on the outside of the dust removal bin 1, and connecting bolts 11 are inserted into the first fixed seats 10;

[0024] As Figures 3-4As shown in the figure, a second sealing plate 12 is fixedly installed at the upper end of the first sealing plate 8. One of the first sealing plate 8 and the second sealing plate 12 is provided with a connecting groove 13, and a connecting block 14 is fixedly installed on the other side of the first sealing plate 8 and the second sealing plate 12. Two second fixing seats 15 are also fixedly installed on one side of the second sealing plate 12. A screw groove 16 is provided at the center position of the upper end of the second fixing seat 15. An installation groove 17 is provided at the lower end of the first sealing plate 8. A plurality of rollers 18 are rotatably installed in the installation groove 17. The second sealing plate 12 is inserted and installed in the telescopic groove 9 inside the dust removal bin 1, and the second fixing seat 15 is threadedly connected with the corresponding connecting bolt 11 through the screw groove 16. A compression spring 19 is sleeved on the connecting bolt 11 located between the first fixing seat 10 and the second fixing seat 15. The connecting groove 13 and the connecting block 14 on one side of two adjacent first sealing plates 8 and second sealing plates 12 are slidably connected with each other. With the action of the compression spring 19, the rollers 18 at the bottom of the first sealing plate 8 always contact the conveyor belt, thereby reducing the distance between the lower end of the dust removal bin 1 and the conveyor belt, and effectively reducing the spillage of dust.

[0025] It should be noted that the present utility model is a biomass fuel non-powered dust removal and material guiding trough device. When the material drops or is vibrated, the dust-containing air flow moves upward and impacts the dust-falling curtain 2, becoming a turbulent flow. The speed and direction of the air flow both change, and large-particle dust settles down accordingly. At the same time, after the dust removal bin 1 is installed on the conveyor by means of a bracket, the plurality of rollers 18 at the bottom of the plurality of first sealing plates 8 at the bottom of the dust removal bin 1 contact the conveyor belt, and with the action of the telescopic groove 9 on the second fixing seat 15, the first sealing plate 8 can always press the plurality of rollers 18 at the bottom against the conveyor belt. When the conveyor belt is running, the conveyor belt will drive the rollers 18 to rotate synchronously, which can effectively reduce the wear of the conveyor belt. At the same time, with the arrangement of the dust removal bin 1 and the first sealing plate 8, it can effectively reduce the dust from moving out through the gap between the dust removal bin 1 and the conveyor belt.
