Description

  The present invention relates to a roll filter device.

  Rolls are used for cleaning the inside air of general spaces, for cleaning outside air and introducing it into general spaces, for cleaning exhaust generated in factory spaces such as work sites and painting booths, and for cleaning liquids, etc. A filter device is used.

Such a roll filter device mainly includes a roll filter, a holding roll for holding the roll filter (hereinafter referred to as a holding roll), and a winding roll for taking up the roll filter (hereinafter referred to as a winding roll). , A power unit such as a motor that can rotate the winding roll, a guide roll that guides the advancing direction of the roll filter fed from the holding roll to the winding roll, and holding parts such as bearings for these main members It is comprised from the chamber which supports by this, and the chamber which accommodates and fixes a flame | frame inside.

  Dust in the filtration target is formed between the openings (suction port and outlet) provided in the chamber so that the roll filter sent out from the holding roll is flat so as to intersect the passing direction of the filtration target. And liquid particles are collected by the roll filter.

  Then, when dust or liquid particles are collected in the flat part of the roll filter and the pressure loss of the roll filter increases and / or when a certain time has elapsed, a power unit such as a motor rotates the winding roll. And a new roll filter is sent out from the holding roll.

Further, when the roll filter device has a limit switch, the rotation of the detection member that rotates according to the amount sent to the winding roll of the roll filter is transmitted to the limit switch, so that the power unit by the limit switch The energization of the power unit is controlled by stopping energization or reducing the energization amount.

  When a roll filter device is used in an environment where a large amount of dust, paint particles, or organic solvent is present in the object to be filtered, such as for purifying exhaust gas generated in a factory space, the power section is shorted and explosion occurs. It is necessary to use a power unit that has been dust-proofed and explosion-proofed so that it does not occur or dust does not enter the power unit to cause a malfunction such as a failure. In addition, when using a roll filter device for the purpose of cleaning liquid, it is necessary to use a water-resistant power unit so that the liquid does not enter the power unit and cause problems such as short circuit or failure. is there.

However, the power unit that has been subjected to dustproof and explosion-proof treatment or water-proof treatment is expensive and large in size, which causes an increase in cost and size of the roll filter device.

As shown in FIG. 4 to FIG. 5, the filter medium presser plate (31) having a rotating shaft referred to here applies a load to the surface of the roll filter (11) and the direction in which the load is applied ( A) refers to a member that can rotate.

However, since it can be used as the detection member (31) as long as it is a member that can rotate according to the amount fed out of the roll filter (11), the filter medium presser plate provided with a rotating shaft as the detection member (31) In addition to (31), the roll filter (11) winds the winding roll (13b), the holding roll (13a) rotatably held by the holding portion, and the first and second guide rolls (14a, 14b). Since it is a member that can rotate when it is fed to the take-up roll (13b), it can be used as the detection member (31).

  Of these members, it is preferable to use a filter medium presser plate (31) having a rotation shaft as the detection member (31) because the remaining amount of the roll filter (11) can be measured from the amount of rotation.

  The reason for this is that when the roll filter (11) is sent out from the holding roll (13a), the outer diameter of the roll filter (11) wound around the holding roll (13a) is reduced according to the amount sent out. It will become. As the outer diameter of the roll filter (11) becomes smaller, the filter medium pressing plate (31) provided with the rotating shaft rotates in the direction (a) in which a load is applied to the surface of the roll filter.

That is, the filter medium presser plate (31) provided with the rotation shaft rotates in proportion to the roll filter (11) being fed out and the remaining amount of the roll filter (11) being reduced. The remaining amount of the roll filter (11) can be measured by using the filter medium presser plate (31) provided with.

  Although not shown, the limit switch (32) is provided in the middle of the energization path to the power unit (18), and the shaft (20b) of the limit switch (32) rotates, so that the power unit (18) It is responsible for controlling the power supply (18) by stopping or reducing the rotation of the power section (18) by stopping or reducing the amount of current.

  The limit switch (32) is provided outside the chamber (16), and the shaft (20b) is inserted into the chamber (16) through the sealing hole (17b).

  In the present invention, the type and form of the limit switch (32) are not limited as long as the type of the limit switch (32) can control the rotation of the power unit (18), but can be suitably used. As the limit switch (32), for example, the rotating shaft (20b) contacts a part of the electric circuit, so that the energization path in the electric circuit changes, and the shaft (20b) rotates without contact. Examples include proximity switches and photoelectric switches to be detected.

Moreover, the limit switch (32) can also have transmissions, such as a sprocket, a chain, and a gear, in the structure.

Next, in FIG. 4 to FIG. 5, in the roll filter device (10) of the present invention, the rotation of the detection member (31) is transmitted to the limit switch (32), so that the limit switch (32) The mechanism for controlling the rotation of (18) will be described.

  As described above, the roll filter (11) is sent out and the detection member (31) rotates. Since the detection member (31) and the shaft (20b) of the limit switch (32) are joined to each other through the universal joint (19b) in the chamber (16), the rotation of the detection member (31) is universal joint (19b ) To the shaft (20b) of the limit switch (32).

  As the shaft (20b) of the limit switch (32) rotates, the energization to the power unit (18) is stopped or the energization amount is reduced, and the rotation of the power unit (18) is stopped or reduced. The

Thus, when the roll filter (11) is sent out and the remaining amount of the roll filter (11) decreases, the limit switch (32) controls the rotation of the power unit (18).

The roll filter device according to the present invention has the above-described configuration, and even when it has an aspect having a limit switch,
1. Since the limit switch is provided outside the chamber, it is not necessary to use a limit switch that is dust-proof and explosion-proof or water-resistant, and the roll filter device can be made smaller and inexpensively manufactured.
2. Since it is not necessary to extend the detection member to the outside of the chamber, it is possible to prevent stress from being applied to the sealing material and holding part when the detection member rotates.
3. Since the manufacture of the chamber is easy, the manufacture of the roll filter device is easy.
4. Easy maintenance,
This is a roll filter device that produces the effect as described above.

The present invention is used for cleaning the inside air of a general space, used for cleaning outside air and introduced into the general space, used for cleaning exhaust generated in a factory space such as a work site or a painting booth, and used for cleaning a liquid. Can be used for etc. In particular, it is a roll filter device that can be suitably used for the purpose of cleaning exhaust generated in a factory space such as a work site or a painting booth.
