Description

Description: TECHNICAL FIELD The present invention relates to a filter for ventilation and dust collection performed by circulating and moving a filter member formed in an endless band shape.

[Conventional technology]

2. Description of the Related Art Conventionally, in a spinning factory and a spinning machine installed therein, a planar or band-shaped air-dust collecting type filter is installed in a factory for the purpose of collecting dust such as floating fly waste or the like. It is built in and provided.

Since these ventilated dust collecting filters are formed into a filter member having a planar or band shape by appropriately weaving or knitting the material, the dust collecting ability of the ventilated filtering surface is reduced when used. Thus, the clogging of the ventilation filtration surface must be removed and cleaned.

[Problems to be solved by the invention]

Conventionally, the cleaning of the above filter member is performed by moving the scraper or the suction port along the ventilation filtration surface manually or by power, or by moving the filter member with respect to the suction port or the scraper. In this case, fly waste or the like adhering to the ventilation filtration surface often flies or scatters at that time to re-contaminate the surroundings, and as a result, there is a problem that efficiency is not good.

In addition, although the filter member is planar, the suction fan has a three-dimensional shape, so that the entire dust collecting device is easily enlarged. Therefore, the dust collecting system for moving the filter member for cleaning is compatible with the mechanical built-in system. For this reason, there is a problem that a low-efficiency manual cleaning system must be used.

In view of such a point, the present invention can be used by being installed in a screen at any place in a factory building by flattening a vented dust collection type filter and incorporating an automatic cleaning function as necessary. The object was to develop a filter that can be easily built in a machine.

[Means for solving the problem]

The configuration of the present invention made in order to solve the above problems,
The first guide line and the first guide line formed at the moving end of the filter main body at an angle of about 45 degrees or near the moving direction of the filter main body at the moving end of the filter main body. Around a turn guide member formed at an angle of about 90 degrees or near to the line and provided with the first guide line and a second guide line forming two sides of an inverted triangle. Thus, the filter body is held in a parallel posture via the turn guide member at both ends in the movement direction, and moves in the posture.

(Operation)

The plate-shaped turn guide member is formed such that the first and second guide lines are symmetrical with respect to a reference line along the moving direction of the filter main body and, as an example, approximately 45 degrees, so that this member has The wrapped filter body is turned through the front and back of the guide member, so that the tension side (forward side) and the loose side (return side) are disposed so as to be able to travel in parallel.
