Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mechanical shaker type bag filter dust removing device capable of efficiently removing dust attached to a filter cloth of a dust collector at an optimum frequency.

[0002]

[Prior art]

 In a bag filter type dust collector, it is necessary to remove dust adhering to the filter cloth by dust collection processing, so it is necessary to periodically remove the dust. A mechanical shaking type is widely used in which the motor is vibrated by a motor to remove dust adhering to the surface of the filter cloth.

However, in the conventional dust removing device of this type of mechanical shaking type bag filter, the shaker pipe that suspends the filter cloth is vibrated by the motor that rotates at a constant rotation speed. The filter cloth always vibrates at a constant frequency. As a result, the vibration of the filter cloth is insufficient depending on the particle size of the collected dust and the dust cannot be reliably removed, which lowers the dust collection capacity. Conversely, excessive vibration is applied to the filter cloth. There is a problem that the life of the filter cloth is shortened remarkably by causing abrasion and damage of the filter. In particular, the filter cloth made of glass-based material had a remarkable tendency to break due to excessive vibration.

[Problems to be solved by the device]

 The present invention solves the above-mentioned conventional problems, and filters dusts adhering to the filter cloth of the dust collector according to various conditions such as the particle size and the adhering amount of the dust, or the material of the filter cloth. By shaking the cloth at the optimum frequency, it is possible to efficiently remove dust, and to prevent wear and damage to the filter cloth due to excessive vibration, and to extend the service life of the filter cloth. It was completed for the purpose of providing a dust removal device for a bag-type filter.

[0005]

[Means for Solving the Problems]

 The dust removing device of the bag filter of the present invention made to solve the above problems is a mechanical shaker for removing dust adhering to the surface of a filter cloth by vibrating a shaker pipe on which the filter cloth is suspended by a motor. In the dust removing device of the bag filter of the formula, a frequency adjusting means for arbitrarily adjusting the frequency of the shaker pipe is incorporated.

[0006]

[Action]

 With this type of structure, a shaker pipe with a filter cloth suspended is vibrated by a motor periodically or when necessary to remove dust adhering to the filter cloth. It is similar to the dust removing device of the seed bag filter, but since the frequency adjusting means for arbitrarily adjusting the frequency of the shaker pipe is incorporated, it can be used for conditions such as the amount of dust adhering to the filter cloth. Correspondingly, the filter cloth can be shaken at the optimum frequency.

【Example】

 Next, the present invention will be described in detail with reference to the illustrated embodiment. In the figure, 1 is a shaker pipe provided with a shaker cover 2 on both sides, 3 is a hook bolt for suspending a filter cloth 4 attached to the shaker bar 2, and 5 is a filter cloth 4 by repeatedly rotating the shaker pipe 1. It is a drive motor 5 for imparting vibration to. Further, 7 is a pulley mounted on the vibration center axis side of the shaker pipe 1, 7 a is a pulley mounted on the motor 5 side, 8 is a V-belt connecting the pulleys 7 and 7 a, and 9 is a shaker pipe for rotating the motor 5. This is a cam mechanism that converts into one vibration motion, and the above-mentioned configuration is the same as that of the conventional dust filter of this kind of bag filter.

Further, the present invention is characterized in that a frequency adjusting means for arbitrarily adjusting the frequency of the shaker pipe is incorporated in the above apparatus. As this frequency adjusting means, as shown in FIG. 3, an inverter controller 6 for controlling the number of revolutions of the motor 5 may be connected to the motor 5 and set by the inverter controller 6. The rotation frequency of the motor 5 is adjusted to an optimum value by arbitrarily adjusting the frequency to be applied, and the filter cloth 4 is shaken at the optimum frequency. Further, the other frequency adjusting means comprises a pulley 7 mounted on the vibration center axis side of the shaker pipe 1 and a pulley 7a mounted on the motor 5 side, which can be freely combined so as to obtain the optimum frequency. The filter cloth 4 can be shaken at an optimum frequency by arbitrarily combining such pulleys 7 and 7a.

In the present invention as described above, the shaker pipe 1 on which the filter cloth 1 is suspended is oscillated by the motor 5 on a regular basis or as needed, similarly to the conventional dust removing device of this type of bag filter. The dust adhering to the filter cloth 4 will be removed, but since the frequency adjusting means for arbitrarily adjusting the frequency of the shaker pipe 1 is incorporated, the particle diameter of the dust adhering to the filter cloth 4 The filter cloth 4 is shaken at the optimum frequency in accordance with the conditions such as the attached amount or the type of filter cloth. That is, when the dust removal effect is poor, the frequency of the inverter controller 6 is adjusted to be increased, and when the vibration is excessive, the frequency of the inverter controller 6 is adjusted to be decreased. It is possible to arbitrarily adjust the frequency of the shaker pipe 1 regardless of the constant number of rotations. In addition to this, a combination of a pulley 7 mounted on the vibration center axis side of the shaker pipe 1 and a pulley 7a mounted on the motor 5 side is calculated in advance so as to give a rotation speed corresponding to the vibration frequency. By replacing the shaker pipe 1, the frequency of the shaker pipe 1 can be arbitrarily adjusted.

[0010]

[Effect of device]

 As is clear from the above description, the present invention makes it possible for the dust adhering to the filter cloth of the dust collector to be optimally vibrated according to various conditions such as the particle size and amount of the dust or the material of the filter cloth. Shaking with a number makes it possible to efficiently remove dust, and prevent the filter cloth from being worn or damaged due to excessive vibration, thereby extending the service life of the filter cloth. In particular, the above effect can be sufficiently exhibited even in a filter cloth made of a glass material. Therefore, the present invention has an extremely large practical value as a dust removing device for a bag filter that solves the conventional problems.

In the present invention as described above, the shaker pipe 1 on which the filter cloth 1 is suspended is oscillated by the motor 5 on a regular basis or as needed, similarly to the conventional dust removing device of this type of bag filter. The dust adhering to the filter cloth 4 will be removed, but since the frequency adjusting means for arbitrarily adjusting the frequency of the shaker pipe 1 is incorporated, the particle diameter of the dust adhering to the filter cloth 4 The filter cloth 4 is shaken at the optimum frequency in accordance with the conditions such as the attached amount or the type of filter cloth. That is, by the case払落dust effectively is poor by adjusting so that increasing the frequency of the inverter controller 6, also in the case of excessive vibration adjusted to lower the frequency of the inverter controller 6, shea Ekapaipu 1 The frequency of can be adjusted arbitrarily.
