Description

Technical Field

[0001] The utility model relates to the field of chemical workshops, in particular to a ventilation device for chemical workshops. Background Art

[0002] A chemical workshop is an area in a chemical plant or chemical industry manufacturing that is specifically used for chemical reactions, substance separation, purification, processing and other process operations. This area is usually equipped with various professional equipment and instruments to support complex chemical processes. The operation of a chemical workshop plays a vital role in the production efficiency, product quality, safety and environmental protection of the entire chemical industry.

[0003] When production is carried out in a chemical workshop, the internal air is easily turbid, so it needs to be ventilated. The existing ventilation usually uses vents and ventilation ducts for ventilation, which not only has a slow ventilation efficiency, but also lacks a filtering function, which easily causes the inner wall of the ventilation duct to be blocked. Utility Model Content

[0004] Based on the above description, the utility model provides a ventilation device for a chemical workshop to solve the problem of low ventilation efficiency in existing chemical workshops.

[0005] The technical solution of the utility model to solve the above technical problems is as follows: a chemical workshop ventilation device, comprising an air guide component fixedly mounted on the workshop wall;

[0006] An air suction portion is provided at one end of the air guide assembly, and a movable assembly is provided at the side wall of the air guide assembly. The air guide assembly includes an air suction hood, a first air guide pipe and a second air guide pipe. A ventilation port is provided on the workshop wall.

[0007] The air intake part includes a fan and a filter plate. The fan is installed on the workshop wall. The air intake hood is installed at the air inlet of the fan. The first air duct is fixedly connected to the air intake hood. The second air duct is movably inserted in the inner cavity of the first air duct. A filter is provided at one end of the second air duct.

[0008] Furthermore, one end of the filter plate is fixedly installed at the air outlet of the fan, and a hole for installing the fan is opened on the workshop wall, and the outer wall of the air hood is in contact with the inner wall of the hole.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the movable assembly includes a threaded rod, a movable plate, a connecting rod, a rotating rod and a base, one end of the threaded rod is fixedly connected to one end of the connecting rod, and the end of the connecting rod away from the threaded rod is installed on the base through a bearing.

[0011] Furthermore, one end of the movable plate is fixedly connected to the side wall of the second air duct, and the movable plate is threadedly connected to the threaded rod, and the end of the movable plate away from the second air duct is movably fitted with the inner wall of the workshop wall.

[0012] Furthermore, there are three rotating rods, which are evenly distributed on the side wall of the connecting rod. The three rotating rods are all located at the lower end of the connecting rod, and the upper end of the connecting rod is fixedly connected to the threaded rod.

[0013] Furthermore, the outer wall of one end of the second air duct is movably fitted with the inner wall of the second air duct, and the second air duct slides up and down on the inner wall of the first air duct, and the second air duct is designed to be L-shaped as a whole.

[0014] Furthermore, a mounting block is fixedly installed at one end of the second air duct away from the first air duct. The mounting block is designed to be annular as a whole, and a threaded hole is provided on the side wall of the mounting block. The frame of the filter screen is fitted on the side wall of the mounting shell, and the frame of the filter screen is fixed to the side wall of the mounting block by bolts.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0016] 1. The utility model installs a fan by opening a hole on the wall of the workshop. The fan can be used in conjunction with the first air duct and the second air duct in the air guide assembly to extract the air inside the workshop, and let the air be discharged to the outside along the first air duct and the second air duct, thereby accelerating the ventilation efficiency.

[0017] 2. By setting a mounting block at the port of the second air duct and using the mounting block to install the filter, the air entering the first air duct can be filtered during the ventilation process to prevent impurities from being deposited on the second air duct and the inner wall of the second air duct. Not only is it difficult to clean, but long-term accumulation can easily block the ventilation work. BRIEF DESCRIPTION OF THE DRAWINGS
