Description

Technical Field

[0001] This application relates to the technical field of kilns, and particularly to a smoke exhaust device for a kiln. Background Art

[0002] Kiln smoke exhaust refers to the soot and waste gas discharged during the operation of a kiln. Kiln smoke exhaust may contain various harmful substances, such as soot, sulfur dioxide, nitrogen oxides, etc., which are harmful to the environment and human health.

[0003] In the related art, a patent with the publication number CN215232886U and the publication date of December 21, 2021 discloses a kiln smoke exhaust device. During the production process of the kiln, the generated soot enters the dust removal fan through the smoke exhaust pipe. With the opening of the smoke baffle, the soot passes through the filtration of two dust removal screens, and the pollution-free gas is discharged through the smoke exhaust port. The filtered dust falls into the dust collection box for recycling.

[0004] In the related art, although the filtration of soot can be achieved, after the filter screen has been used for a relatively long time, it is prone to blockage, thereby affecting the filtration effect of the soot. Utility Model Content

[0005] In order to reduce the occurrence of blockage of the filter screen, this application provides a smoke exhaust device for a kiln, and adopts the following technical solutions:

[0006] A smoke exhaust device for a kiln, comprising:

[0008] A filter assembly, one end of which is connected to the other end of one of the smoke exhaust pipes, and is used for filtering soot; the filter assembly includes multiple layers of filter screens, and the multiple layers of filter screens slide reciprocally relative to the smoke exhaust pipe;

[0009] An activated carbon adsorption assembly, one end of which is connected to the filter assembly, and the other end of which is connected to one end of the other smoke exhaust pipe, and is used for adsorbing harmful gases;

[0010] A collection box, which is installed on the filter assembly and is used for collecting the filtered waste residue.

[0011] By adopting the above technical solutions, the soot from the kiln exhaust enters the smoke exhaust pipe, passes through the filtration of the filter assembly and the adsorption of the activated carbon adsorption assembly, and then is discharged from the smoke exhaust pipe. The collection box collects the waste residue from the soot filtration; due to the reciprocating sliding arrangement of the multiple layers of filter screens, the occurrence of blockage of the filter screen can be reduced.

[0012] Optionally, the filter assembly includes:

[0013] A filter housing, detachably connected to the exhaust pipe;

[0014] A filter plate, slidably connected within the filter housing; the multi-layer filter screen is installed on the filter plate, and the diameter of the filter holes gradually decreases towards the activated carbon adsorption component;

[0040] A sliding block, which is slidably connected to the connecting block and can be clamped inside the filter block;

[0041] A locking member, which is installed on the connecting block and is used to lock the sliding block.

[0042] By adopting the above technical solution, after the connecting block abuts against the filter block, slide the sliding block so that the sliding block is clamped inside the filter block, and then lock the sliding block through the locking member to realize the installation between the activated carbon housing and the filter housing.
