Description

Technical Field

[0001] The utility model relates to the technical field of ventilation equipment, in particular to brick kiln ventilation equipment with a filtering structure. Background Art

[0002] A brick kiln is a facility specially used for firing bricks and tiles. It is generally composed of a kiln body, combustion equipment, flue, etc. The kiln body is the main place for brick production, with bricks laid inside; the combustion equipment usually includes gas furnaces, oil furnaces, etc., which are used to raise the temperature inside the kiln to the required firing temperature; the flue is used to discharge combustion exhaust gas and maintain ventilation inside the kiln.

[0003] When workers are working in a brick kiln, the air inside the brick kiln is relatively dirty, so ventilation equipment is an indispensable part of the brick kiln, which is mainly responsible for the ventilation of the brick kiln; however, the existing brick kiln ventilation equipment has certain limitations when used. Although they can complete the basic ventilation function, that is, to exchange the air in the brick kiln with the outside world, in this process, the air in the brick kiln containing a large amount of dust and other pollutants is often directly discharged to the outside world. This direct emission method not only fails to effectively filter and reduce pollutants, but also aggravates the pollution of the atmospheric environment and imposes unnecessary burden on the environment. In view of this, we propose a brick kiln ventilation device with a filtering structure. Utility Model Content

[0034] In this embodiment, a sewage outlet is provided at the front bottom of the ventilation box 1, and a bracket 16 is provided below the sewage outlet. A bracket box 17 with an open top is slidably mounted at the opening of the bracket 16, and the bracket box 17 is used to collect dust scraped off the net cylinder 30 by the bristles 20; a fixing bolt 161 is threadedly connected to the bottom of the bracket 16, and the top of the fixing bolt 161 passes through the bottom of the bracket box 17. This design can conveniently collect and process the dust scraped off the net cylinder 30 by the bristles 20. This design not only improves the cleaning efficiency, but also reduces the secondary pollution caused by the scattering of dust.

[0035] In this embodiment, the inner wall of the ventilation box 1 is located at the upper and lower sides of the notch and is fixedly connected to two guide rails 14 by bolts, and the plate body 40 is located between the two guide rails 14 and can slide along the guide rails 14.

[0043] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
