Abstract

The utility model provides an improvement type dry-type dust catcher, the utility model relates to a dust collector technical field indicates an industrial dry-type dust shaker especially. The method is realized by the following technical scheme: guide pillar fixed mounting is on the bottom plate with filter screen rigid connection, vibrator slides and sets up on the guide pillar, vibrator include connecting rod, upper and lower spacing piece, upper and lower spring, handle, upper and lower connecting plate, drive hammer etc. and constitute, through with external force pulling handle for the connecting rod rises along the guide pillar under the effect of upper and lower spacing piece, and owing to fix the effect of stop screw on the guide pillar, lower spacing piece is obstructed, and lower spring is pressed, gets rid of external force, and under the effect of restoring force of lower spring, on hitting the hammer impact and hitting the bottom plate with filter screen rigid connection as an organic whole with the connecting plate, produce vibrations, thereby shake dust on the filter screen down. The utility model discloses simple structure need not improve former dust collector, great improvement the life of filter screen, and improved dust collector's efficiency.

Description

An improved dry vacuum cleaner

Technical field:

The utility model relates to the technical field of dedusting devices, in particular to an industrial dry dedusting machine.

Background technique:

As we all know, the dry dust collection devices at home and abroad all use fans to suck the dust into the closed ash box, and then filter the dust through the filter screen to discharge the gas. However, in the process of use, people often find that the dust to be filtered is adsorbed on the filter screen. Over time, thick dust is deposited on the filter screen, so that the efficiency of the dust collection device is reduced, and the user has to replace the filter screen to improve the filtration efficiency. Efficiency, not only increases the cost of dust removal, but also delays the operation time.

Utility model content:

The purpose of this utility model is to overcome the shortcomings of the above-mentioned prior art, and provide a vibrating device arranged in the filter net, and manually hit the bottom plate rigidly connected with the filter net to remove the dust adsorbed on the filter net. An improved dry vacuum cleaner.

The utility model is realized through the following technical scheme: the guide column is fixedly installed on the bottom plate rigidly connected with the filter net, the vibration device is slidably arranged on the guide column, and the vibration device includes a connecting rod, an upper and a lower limit block, an upper , lower spring, handle, upper and lower connecting plates, hammer, etc., by pulling the handle with external force, the connecting rod rises along the guide post under the action of the upper and lower limit blocks, and because the limit block fixed on the guide post Under the action of the position screw, the lower limit block is blocked, the lower spring is compressed, and the external force is removed. Under the action of the restoring force of the lower spring, the hammer integrated with the connecting plate hits the bottom plate rigidly connected with the filter net to generate vibration, thereby The dust on the filter is shaken off.

The utility model has a simple structure, does not need to improve the original dust removal device, greatly improves the service life of the filter screen, improves the efficiency of the dust removal device, and has good use effect.

Description of drawings:

Accompanying drawing 1 is the three-dimensional exploded view of the utility model

Accompanying drawing 2 is the sectional view of the utility model

Detailed ways:

See accompanying drawing 1,2, the utility model comprises suction pipe A, ash box B, filter screen C and vibration device D. One end of the suction pipe A is fixed on the side wall of the ash box B, one end of the filter screen C is fixed in the ash box B, and the bottom plate 9 that the other end of the filter screen C is closed is rigidly connected to the filter screen C. The guide post 1 is fixedly installed on the bottom plate 9 rigidly connected with the filter screen, and the vibrating device is slidably arranged on the guide post 1. The vibrating device D includes a connecting rod 2, a handle 3, upper and lower limit blocks 4, upper and lower Spring 6, upper and lower connecting plate 7, hammer 8 etc. constitute. The upper and lower limit blocks 4 are respectively sleeved on the two ends of the limit screws 11 on the guide column 1, and the connecting rod 2 respectively passes through the upper and lower limit blocks 4 and is connected with the upper and lower connecting plates 7 to form a whole. , Between the lower limit block 4 and the connecting plate 7, the connecting rod 2 is pierced with upper and lower springs 6, on the lower connecting plate 7, a hammer 8 that can contact the closed bottom plate 9 is fixed, and the handle 3 is fixed. On the upper connecting plate 7 , the other end of the guide column 1 is inserted into the groove of the handle 3 .

When using the utility model, if dust is deposited on the filter screen C, pull the handle 3 upwards by hand, and the handle 3 will make the connecting rod 2 rise through the upper and lower connecting plates 7, and the upper and lower connecting rods 2 will rise together. The lower limit block 4 and the upper and lower springs 6, when the lower limit block 4 meets the limit screw 11 on the guide post 1, the lower limit block 4 is blocked and stops moving, the lower spring 6 is pressed, and the hammer 8 is also Rise up with the connecting rod 2; loosen the handle 3, the lower spring 6 recovers the compression deformation, so that the connecting rod 2 quickly moves downward along the guide post 1, and the hammer 8 hits the bottom plate 9 rigidly connected with the filter screen, and the sticky The dust attached to the filter screen C shakes off; at the same time, the upper connecting plate 7 also quickly moves downward along the guide post 1, and because the upper limit block 4 stops at the limit screw 11 on the guide post 1 , the upper spring 6 well buffers the impact force of the hammer 8 when the connecting rod 2 quickly moves downward along the guide post 1, and so on, so that all the dust on the filter screen is shaken down.
