Still another object of the present invention is to provide a venturi for a bag filter dedusting facility in which the venturi mounted on the upper portion of the filter cage is not easily separated by air pressure.

The present invention for achieving the above object is a bag filter dedusting equipment venturi coupling device, the filter bag 18 is installed on the lower side of the filter cage upper cap 16 is bent to the tube sheet 15, the bag filter is installed In the dust removal equipment,

A spring guide groove 17 and an inner upper side of the filter cage upper cap 16 are inserted into the guide groove 17 of the filter cage upper cap 16 so as to be coupled downward to an upper side of the venturi 11. A groove 13 formed in the stepped portion 12 formed to be gradually narrowed in the shape, a spring steel 14 provided in the groove 13 to have elasticity, and the venturi 11 are disposed inside the filter bag 18. The spring steel 14 mounted in the groove 13 of the venturi 11 to be positioned and fixed is inserted into the spring guide groove 17 of the upper portion of the filter cage 16 so as not to be easily detached. do.

The present invention as described above has the effect that the venturi for bag filter dust removal equipment is coupled to the upper portion of the filter cage cap is not easily separated by the air pressure.

In addition, a groove is formed in the upper side of the venturi, and an elastic spring steel is inserted into the groove to form a spring guide groove in the bent filter cage upper cap, so that the venturi is easily attached to the filter gauge upper cap. have.

In addition, the venturi mounted on the filter cage upper cap is not easily released by the air pressure, and the user can easily mount and detach the venturi on the filter cage upper cap.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood, however, that the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth. Note that the same reference numerals are used for the same parts in the drawings of the present invention.

3 is a state diagram in which the bag filter dust removal cost venturi coupling device of the present invention is separated, and FIG. 4 is a state diagram in which the bag filter dust removal equipment venturi coupling device of the present invention is coupled.

The present invention relates to a venturi coupling device for bag filter dedusting equipment, and more particularly, a venturi coupling device for bag filter dedusting equipment, in which a venturi for bag filter dedusting equipment is coupled to an upper cap of a filter cage so that it is not easily released to air pressure. It is about.

3 and 4, the present invention will be described below.

The present invention relates to a venturi coupling device for bag filter dedusting equipment, wherein in the bag filter dedusting equipment in which a filter bag 18 is installed on a lower side of a filter cap upper cap 16 installed to be bent on the tube sheet 15,

A spring guide groove 17 is formed on the inner upper side of the filter cage upper cap 16. The groove 13 is formed in the stepped portion 12 formed to be gradually narrowed downward in the upper side of the venturi 11 to be inserted into the spring guide groove 17 of the filter cage upper cap 16. . A spring steel 14 having elasticity is provided in the groove 13. The spring guide groove 17 of the filter cage upper cap 16 is a spring steel 14 mounted in the groove 13 of the venturi 11 so that the venturi 11 is positioned and fixed inside the filter bag 18. ) So that it is combined so that it is not easily separated.

The spring steel 14 installed in the upper groove 13 of the venturi 11 is installed so that only half of the spring steel 14 is inserted into the groove 13.

The spring steel 14 is a spring steel having one side of a resilient spring.

The spring guide groove 17 formed in the filter cage upper cap 16 is formed in a semicircular shape.

The venturi coupling device for bag filter dedusting device as described above forms a spring guide groove 17 in the upper portion of the upper portion of the filter cage upper cap 16 installed to be bent in the tube sheet 15, and the The groove 13 is formed in the stepped portion 12 formed to become narrower in the downward direction on the upper side, and the spring steel 14 having elasticity is provided in the groove 13.

In the above state, when the venturi 11 is mounted downward from the top of the filter bag 18 so that the venturi 11 is positioned and fixed inside the filter bag 18, the groove 13 of the venturi 11 is disposed. When the spring steel 14 mounted on the filter guide upper cap 16 is located in the spring guide groove 17, a portion of the spring steel 14 is inserted into the guide groove 17 by the elastic force and the upper part of the filter cage. The cap 16 and the venturi 11 are combined so as not to be easily separated.

In the above state, even when air is used to remove dust from the surface of the filter bag 18, the venturi 11 is inserted into the spring guide groove 17 of the upper cap 16 of the filter cage. Since the spring steel 14 having elasticity installed in the upper groove 12 is coupled in the inserted state, the venturi 11 is not separated from the filter cage upper cap 16 by air pressure.

When the venturi 11 is to be removed from the filter cage upper cap 16 in the above state, the spring guide groove of the filter cage upper cap 16 is lifted upward by holding the top of the venturi 11 and applying a force. The spring steel 14, which was positioned at 17, receives elasticity and exits from the guide groove 17. At this time, the spring steel 14 is to be separated from the filter cage upper cap 16 in the venturi 11 in a state installed in the groove 12 of the venturi (11).

As described above, the spring spring 14 having an elasticity installed in the upper groove 12 of the venturi 11 is inserted into the spring guide groove 17 of the upper cap 16 of the filter cage and is coupled to the filter bag 18. The venturi 11 is not separated from the upper portion of the filter cage cap 16 even when pneumatic dust is used to remove dust.

The preferred embodiment of the present invention has been described above. The present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but it will be apparent to those skilled in the art that various modifications are possible without departing from the scope of the present invention.
