Description

Chemical safety ventilation device

Technical Field

The utility model relates to the technical field of chemical industry, in particular to a chemical safety ventilation device.

Background

Chemical industry is an abbreviation for "chemical process", "chemical industry", "chemical engineering", etc. All techniques for changing the composition, structure or synthesizing new substances by chemical methods belong to chemical production techniques, namely chemical processes, and the obtained products are called chemicals or chemical products.

The chemical industry factory generally generates inflammable, explosive and toxic harmful gas in the production process. In order to ensure normal operation of production and to ensure a working environment of occupational health and safety of operators, normal ventilation is required in the factory building. In order to prevent harmful gases generated in the production process from diffusing into other spaces, the harmful gases need to be filtered and then discharged, a plurality of filtering devices exist in the prior art, the devices need to be maintained regularly in the use process, the maintenance needs to be stopped, the harmful gases generated in the maintenance process cannot be filtered, and the air is polluted and needs to be improved.

Disclosure of Invention

The technical problem to be solved by the utility model is to overcome the difficulty and provide the chemical safety ventilation device which is convenient to maintain and can effectively treat harmful gas generated during the maintenance.

In order to solve the technical problems, the technical scheme provided by the utility model is as follows: the utility model provides a chemical industry safety ventilation device, includes air-supply line, exhaust pipe and locates the filter equipment between air-supply line, the exhaust pipe, be equipped with the fan in the air-supply line, filter equipment includes the body and locates the conical tube of body both ends respectively with air-supply line and exhaust pipe intercommunication, be equipped with the division board in the body, the one end that the division board is close to the air-supply line is equipped with rotatable and with air-supply line matched with baffle, be equipped with the filtration box that the symmetry set up in the body.

As an improvement, the pipe body is provided with symmetrically arranged openings, and the filter box body is arranged in the openings.

As an improvement, one end of the filter box body, which is positioned outside the pipe body, is fixedly provided with a mounting plate, and the mounting plate is connected with the pipe body through bolts.

As an improvement, the partition plate is provided with a symmetrical ring at one end close to the air inlet pipe, a rotating shaft is arranged in the ring, the baffle is fixedly arranged on the rotating shaft, and a hexagonal prism is connected and arranged at one end of the rotating shaft extending to the outer side of the pipe body.

Compared with the prior art, the utility model has the advantages that: the air inlet pipe, the filtering device, the exhaust pipe and the fan are matched, so that harmful gas can be treated; the number of the filtering box bodies is two, and the filtering box bodies are matched with the baffle plates, so that the filtering device can be maintained under the condition that a chemical plant is not stopped, and the filtering box bodies are replaced.

As shown in the figure: 1. the air inlet pipe, 2, the exhaust pipe, 3, the filter equipment, 4, the fan, 5, the body, 6, the conical tube, 7, the division board, 8, the baffle, 9, the filtration box, 10, the opening, 11, the mounting panel, 12, the bolt, 13, the ring, 14, the pivot, 15, hexagonal prism.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

1-2, a chemical industry safety ventilation device, including air-supply line 1, exhaust pipe 2 and locate air-supply line 1, exhaust pipe 2 between filter equipment 3, be equipped with fan 4 in the air-supply line 1, filter equipment 3 includes body 5 and locates the conical tube 6 that body 5 both ends communicate with air-supply line 1 and exhaust pipe 2 respectively, be equipped with division board 7 in body 5, the one end that division board 7 is close to air-supply line 1 is equipped with rotatable and with air-supply line 1 matched with baffle 8, be equipped with the filtration box 9 of symmetry setting in the body 5.

The pipe body 5 is provided with symmetrically arranged openings 10, and the filter box body 9 is arranged in the openings 10.

One end of the filter box body 9, which is positioned outside the pipe body 5, is fixedly provided with a mounting plate 11, and the mounting plate 11 is connected with the pipe body 5 through a bolt 12.

The baffle plate 7 is close to the ring 13 that the symmetry set up that one end of air-supply line 1 was equipped with, be equipped with pivot 14 in the ring 13, baffle 8 set firmly in pivot 14, the one end of pivot 14 stretches out to the outside connection of body 5 and is equipped with hexagonal prism 15.

In the concrete implementation of the utility model, harmful gas generated in the production process of chemicals is guided by the fan 4, guided by the air inlet pipe 1 and the baffle plate 8, enters the pipe body 5 on the filtering device 3, is filtered by the filtering box body 9 on the filtering device 3 and is discharged from the exhaust pipe 2, when people need to maintain the filtering box body 9, the people only need to sleeve the filtering box body 9 on the hexagonal prism 15, rotate the hexagonal prism 15 to drive the rotating shaft 14 to rotate, and further drive the baffle plate 8 to rotate, so that the baffle plate 8 is abutted against the air inlet pipe 1 to guide the gas, and the worker can take down the filtering box body 9 to maintain the filtering box body 9 by the disassembling bolt 12.
