Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a dust collector.

[0002]

2. Description of the Related Art There are various types of dust collectors, and one of them is a dust collector using a filter. A conventional dust collector using this filter is, for example, a dust collector as shown in FIG. 6, in which a plurality of filter bodies 2 are arranged in a main body casing 1, and the introduced dust-collected gas G is the filter. The dust is removed by the filter body 2 as it passes through it. The dust collected by the filter body 2 directly lowers the dust collecting effect of the filter body 2. Therefore, for example, it is necessary to periodically vibrate the filter body 2 and drop it into the hopper 3 below. As a structure for vibrating the filter body 2, a structure as shown in FIG. 7 is conventionally known. That is, the filter body 2 is supported in the main body casing 1 from above and below by the springs 4, the vibrating means 5 is arranged outside the ceiling of the main body casing 1, and the vibration by the vibrating means 5 is passed through the connecting rod 6 to The structure is such that the filter body 2 is connected and fixed to the connecting rod 6, and the filter body 2 is vibrated in the vertical direction. By vibrating the filter body 2 in the vertical direction, dust attached to the filter body 2 is shaken off.

[0003]

However, in the above-mentioned conventional dust collector, the filter body 2 is supported by the spring 4 so as to be swingable in the main body casing 1. In an environment in which a high temperature gas is used as the dust gas G, the temperature inside the main body casing 1 rises to several hundreds of degrees, so that the spring 4 is fully extended within a relatively short period of time. However, there is a problem in that the good dust collection effect cannot be maintained for a long period of time. Therefore, there is a problem that replacement work of the spring 4 and the like must be performed in a short period. In addition, in the conventional device, since the reproduction by the vibration of the filter body 2 is performed only by the simple vibration in the vertical direction, it is easy to shake off the dust attached to the filter body 2,
It was not possible to prevent the deterioration of the dust collection performance due to clogging with time. Therefore, there is a problem that the filter attached to the filter body 2 must be replaced in a short period.

Therefore, the present invention solves the above-mentioned drawbacks of the conventional dust collectors, and even when the filter is used in a high temperature atmosphere, the filter body can be satisfactorily regenerated by the vibration of the filter body for a long period of time, and at the time of each regeneration. The filter body can be vibrated sufficiently effectively to satisfactorily shake off the adhered dust, and therefore, the dust can be satisfactorily collected for a long period of time whether or not it is used in a high temperature atmosphere. An object is to provide a dust device.

A rib 42d is provided on the upper surface of the main body casing 10 via a seat frame 42a and a seat plate 42b, and four vibration receiving springs are provided between the seat frame 42a and the seat plate 42b on the upper surface of the rib 42d and the vibration base body 40. 41 is interposed. The seat frame 42a, the seat plate 42b, the seat frame 42a, and the ribs 42d form a pedestal 42. A vibration motor 50, which is a vibrating means, is fixed to the center of the upper surface of the vibration base body 40 supported by the vibration receiving spring 41, and the tip of the connecting rod 60 from below is connected to the center of the vibration base body 40. It is fixed. In the pedestal 42, the spring receiving seat 42c is appropriately separated from the ceiling wall 11 of the main body casing 10 by the rib 42d in the vertical direction. To prevent. Generally, a spring receives heat so that its spring characteristics are easily lost. The vibration base body 40, together with the vibration receiving spring 41, receives the vibration of the vibration motor 50 as it is and vibrates. The vibration of the vibration base body 40 is transmitted to the filter body 20 via the connecting rod 60.

The vibration of the filter body 20 is not a conventional simple vertical vibration but a combined vibration of vertical vibration and horizontal vibration. More specifically, for example, the elliptical vibration in which the major axis is obliquely displaced from the vertical direction is applied to the filter body 2
It can be given to 0. In this case, the vibration motor 50 uses the vibration motor 50 that gives an elliptical vibration as a vibrator that is a vibration generating means. By vibrating the vibration of the filter body 20 not only in the up and down direction but also in the left and right direction as a combined direction thereof, the vibration is diversified, and the effect of removing dust adhering to the filter body 20 can be sufficiently improved. it can. Of course, the vibration base body 40 that receives the vibration from the vibration motor 50

The vibration base body and the main body are arranged outside the main body casing, and a vibration means for giving a combined vibration in the vertical and horizontal directions and a vibration base body with a vibration receiving spring vibrated by the vibration by the vibration means are arranged. By connecting and fixing with the connecting rod between the filter body in the casing,
Since the filter body is configured to vibrate vertically and horizontally integrally with the connecting rod, the vibration receiving spring necessary for vibrating the filter body can be arranged outside the main body casing, so that the temperature inside the main body casing is high. Even when the vibration receiving spring is used in an environment where the atmosphere is present, the performance deterioration of the vibration receiving spring can be reliably prevented. Further, the filter body can be satisfactorily regenerated for a long period of time, whereby a good dust collecting function can be maintained for a long period of time. In addition, since the filter body is vibrated not only in the vertical direction but also in the vertical direction and the horizontal direction during the regenerating operation, the effect of shaking off the adhered dust can be sufficiently improved. Therefore, the degree of regeneration of the filter body can be sufficiently increased, and good regeneration and good dust collecting effect can be provided over a long period of time. Further, according to the dust collector of claim 2, in addition to the effect of the configuration of claim 1, the filter body has an outer frame that moves up and down between the outer frame and the receiving frame formed on the inner surface of the main body casing. Since it is loosely fitted to the left and right, it is possible to vibrate the filter body vertically and horizontally without holding the filter body in the main body casing with a heat-sensitive spring or the like. Therefore, even in an environment of high temperature use, it is possible to satisfactorily regenerate the filter body for a long period of time, and it is possible to effectively perform vibration during regeneration. Further, according to the dust collector of claim 3, in addition to the effect of the configuration of claim 1 or 2, since the combined vibration in the vertical and horizontal directions by the vibrating means is an elliptical vibration by the vibration motor, it is complicated. Therefore, the vibration motor can vibrate the filter body without using an expensive vibration device. Moreover, the elliptic vibration can sufficiently shake off the dust.
