Description

A gas filter device that is easy to load and unload

technical field

The invention belongs to the technical field of gas filtration, and in particular relates to a gas filtration device which is convenient for loading and unloading.

Background technique

A gas filter is a device that captures dust from a gas-solid two-phase flow through the action of a porous filter material and purifies the gas. The dust particles of the diameter are captured and adsorbed to improve the air quality;

The existing gas filtration method is to transmit the gas carrying impurity particles into the filter, and separate and filter the impurity particles through the filter screen. During the installation process of the filter, tooling is usually used to rotate the filter to make the filter. It can be screwed together with the separation tank;

In the existing gas filtration method, in the filtration of large-flow gas, it is easy to cause deformation of the filter screen, thereby causing impurity particles to flow in the deformation gap of the filter screen, reducing the filtering effect of the gas, and in the filter. During installation, due to the problem of the thread direction at both ends of the filter, it is difficult to completely screw and fix the filter, and it is very easy to cause the device to fall off during the process of rotating and filtering.

The technical scheme of the present invention is: including a cover plate, a filter element, an end cover, a bearing, a supporting part and a clutch part, the cover plate and the end cover are symmetrically installed on both ends of the filter element, and the three are connected in turn by screws . The easy-to-install gas filter device also includes:

A support member, which is installed inside the filter element and located between two bearings in the filter element, has a degree of rotational freedom. When the component rotates, under the action of inertial force, it can be stretched along the radial direction to support the inner surface of the filter element, preventing the filter element from being greatly deformed under the action of air flow, and reducing the filtering effect;

The clutch part is connected with the support part by spline connection, and is located inside the filter part, between the second bearing and the end cover; the rotation of the clutch part can drive the support part to rotate synchronously.
