Description

A dust collection device for a construction waste treatment line Technical Field

[0001] This utility model relates to the field of construction waste treatment technology, and in particular to a dust collection device for a construction waste treatment line. Background Technology

[0002] Construction waste is a major component of urban solid waste. It is chemically stable, acid and alkali resistant, and has high physical strength. After processing, it can be transformed into resources such as recycled aggregates and environmentally friendly building materials. It accounts for 30%-40% of the total urban waste. It is mainly composed of waste concrete blocks, waste bricks and tiles, mortar, metal, wood, etc. When processing construction waste, the dust is easily raised, which affects the health of workers.

[0003] A search revealed Chinese patent application number 202020599898.X, which discloses a dust collection device for construction waste treatment. The device includes a mobile trolley with two symmetrically arranged columns, a first hydraulic cylinder, and a dust collection box mounted on it. A lifting dust removal mechanism, connected to the first hydraulic cylinder via transmission, is movably mounted on the columns. This utility model relates to the field of construction waste treatment technology. This utility model solves the problem that dust collection devices for construction waste treatment are typically fixed in one location, making installation difficult due to the often lack of suitable installation sites, requiring a platform for support, and necessitating the use of a ladder if installation at a high location is needed. Furthermore, the suction direction must be fixed, making operation very cumbersome.

[0004] Although the aforementioned patent allows for adjustment of the suction direction and height, it requires filtering dusty air through a cloth bag during use. After a period of filtration, dust will clog the cloth bag, leading to a decrease in filtration efficiency. Cleaning requires removing the cloth bag, which is cumbersome and affects the dust collection efficiency.

[0005] Therefore, there is an urgent need for dust collection devices in construction waste treatment lines to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to solve the problem in the prior art where the dust adhering to the cloth bag needs to be removed during cleaning, resulting in a decrease in dust collection efficiency. Therefore, this invention proposes a dust collection device for a construction waste treatment line.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A dust collection device for a construction waste treatment line includes a dust collection bin. One end of the dust collection bin is connected to a feed hopper via a suction pipe.

A sleeve is installed at the outer end of the support rod. An annular air pipe is installed inside the sleeve. Multiple air nozzles are evenly installed on the outer side of the annular air pipe. The annular air pipe is connected to the air outlet of the blower via a guide pipe.

[0009] As a preferred technical solution of this application, a bracket is fixedly installed at one end of the dust collection bin below the air suction pipe, and a first electric telescopic rod is fixedly installed above the outer end of the bracket. A support is fixedly connected to the output end of the first electric telescopic rod, and the support is connected to the outer end of the air suction pipe.

[0010] As a preferred technical solution of this application, telescopic support rods are fixedly installed on both sides of the first electric telescopic rod, and the top of the telescopic support rod is connected to the bottom of the support.

[0011] As a preferred technical solution of this application, the inner top of the collection box is provided with a conveyor belt, and both ends of the conveyor belt are provided with support rollers. One of the support rollers is connected to the output end of the motor, and multiple loading slots are evenly opened on the outer surface of the conveyor belt.

[0012] As a preferred technical solution of this application, inclined platforms are installed at both ends of the top of the collection box.

[0013] As a preferred technical solution of this application, the filter bag is installed on the filter bag frame plate, and a slide is provided at the top of the other end of the dust collection bin.

[0014] As a preferred technical solution of this application, the inside of the bag is provided with a support assembly. The support assembly includes an installation ring fixedly installed with the bag frame plate. Multiple uprights are installed in a ring shape at the bottom of the installation ring, and multiple ring frames are evenly installed on the multiple uprights.

[0015] Compared with the prior art, this utility model provides a dust collection device for a construction waste treatment line, which has the following beneficial effects:

[0016] 1. The dust collection device of this construction waste treatment line, through the set air blowing mechanism, addresses the issue that after a period of filtration, a large amount of dust will accumulate on the outer surface of the filter bag, leading to a decrease in its filtration efficiency. By raising and lowering the air blowing mechanism inside the filter bag and then spraying air through the nozzle, the dust on the outside of the filter bag is blown off, thus cleaning the filter bag and improving its filtration efficiency. This solves the problem in the prior art that the filter bag needs to be removed for cleaning, which leads to a decrease in dust collection efficiency.

[0017] 2. The dust collection device of this construction waste treatment line collects filtered dust through a collection box. At the same time, a conveyor belt is installed inside the collection box to transport the collected dust to the collection box. The conveyor belt can also act as an isolation device to prevent the dust collected in the collection box from being re-entrained. This solves the problem in the prior art where dust collected in the collection box is re-entrained due to airflow, which increases the difficulty of bag filtration. Attached Figure Description
