Description

Automatic Roll Filter Unit {AUTOMATION ROLL FILTER APPARATUS}

The present invention forms a roll filter for removing foreign matter or dust in the air circulated by installing in an air conditioning system such as a railroad or a bus vehicle or an industrial large air conditioning system, while increasing the contact area of the roll filter. The present invention relates to an automatic roll filter device that improves dust collection of a filter and automatically winds up a predetermined length after detecting a state of the filter after a predetermined time.

In general, large commercial vehicles such as railroad cars or express buses are mainly used for long-distance travel at high speeds, and many passengers ride in closed vehicles for a long time, so that passengers are not provided with air conditioning. As it causes a lot of inconvenience, an air conditioning system is installed in order to control the interior space of the vehicle to the most suitable temperature, humidity, and air flow distribution and to remove foreign substances and dust in the air.

Meanwhile, an air conditioning system is installed to protect the environment by protecting products from foreign substances or fine dust generated in industrial large-scale production facilities or production lines and maintaining reliability, as well as collecting harmful substances generated.

Thus, in particular, the roll filter device of the configuration of the air conditioning system as shown in Figure 1a, 1b is composed of a roll filter, housing, grill cover and frame.

That is, the housing 20 is fixed to the ceiling of the vehicle or production line, a predetermined space is formed to accommodate the roll filter 10, the air is circulated therein, the grill cover 30 The grille (32) is formed over the front surface to suck the air in the room to cover the lower portion of the housing 20, one side thereof is coupled to the lower end of the housing 20 and the hinge 34 can be opened and closed. Is formed.

In addition, the frame 40 is a base for installing the roll filter 10 is hinged to the inside of the housing 20 is formed so as to be accessible from the housing, the bottom 32 in contact with the grill 32 An opening 42 having a predetermined width is formed in the surface to allow air to flow from the grill, and a pair of rotary shafts 46 and a driving motor for installing the roll filters 10 on both sides are formed on the rear surface of the frame 40. 50 are respectively installed, and guide rollers 48 are installed at both ends of the opening 42.

Therefore, according to such a configuration, when the air conditioning system is operated, air in the room is introduced through the grill 32, and the introduced air is drawn out to block the opening 42 of the frame 40. When the pollutants are collected by the bar, when the pollutants are collected at a predetermined ratio or more on the surface of the filter 10, the pollutants are sensed to operate the driving motor 50, so that the roll filter 10 installed on the rotary shaft 46 is A new filter 10 surface is positioned in the opening 42 as it is wound to the other side, allowing continuous filter action.

However, according to such a conventional automatic roll filter device, the problem that dust collection of a roll filter is weak is raised first. That is, since the filter surface located in the opening is flatly laid out by both guide rollers, the contact area with the introduced air is extremely limited to the width of the opening, thereby limiting the dust collection of the foreign matter contained in the air.

In addition, the roll filter is formed by weaving a metal yarn or a synthetic resin into a net form in order to maintain rigidity against a predetermined pressure. As a result, the roll filter cannot sufficiently collect fine foreign matter or odor through each mesh of the net. In addition, the efficiency is greatly reduced as a means for forcibly collecting dust against extremely fine foreign matters and the like is not provided.

In addition, another problem is pointed out that a drive motor is used as a means for winding the roll filter, which simply rolls the roll filter by a certain number of rotations of the drive motor, thereby reducing the length of the roll filter surface located in the opening. There is a lot of difference. In other words, if the rotational ratio of the drive motor is set to 10 times, the length of the filter withdrawn from the original roll will be long, but the length of the filter withdrawn from the intermediate roll is shorter than the original.

Therefore, an excessive and minor phenomenon occurs in the filter to be drawn out, which causes inefficiency and economical problems, and therefore an urgent alternative is required.

The present invention has been made to solve the above problems and shortcomings, the main purpose is to improve the dust collection to the particulate matter or foreign matter in the indoor air circulated into the air conditioning system such as large commercial vehicles or industrial production line In addition, the present invention provides an automatic roll filter device that generates static electricity on the contact surface of the roll filter and further increases the contact surface of the roll filter with respect to indoor air.

Another object of the present invention is to form the roll filter, but in order to maintain the rigidity of the filter according to the take-out and winding, and to improve the dust collection to the fine particles, the automatic roll filter device formed integrally with the net layer and microfiber layer Is to provide.

Another object of the present invention is to drive the filter roll after a predetermined time to draw out a new filter surface, but the economic loss or deterioration of the filter efficiency, etc. It is an object of the present invention to provide an automatic roll filter device capable of automatically controlling a proper drawing length of a roll filter.
