Description

A stone shot blasting dust removal device

technical field

The utility model relates to the field of engineering machinery, in particular to a stone shot blasting dust removal device.

Background technique

The stone shot blasting machine will produce a lot of stone dust when roughening the stone with smooth surface. The particle size of stone dust is small, light in weight, low in density, and contains a large amount of silica which is harmful to human body. This type of dust uses dry dust removal, the dust removal effect is not good, and it is difficult to maintain stability. Because the particle size of stone dust is small, light in weight and low in density, when the fan on the traditional dust collector is working, the pulse back-blowing dust cleaning device cannot blow away a large amount of stone dust adsorbed on the filter bag, and a large part of the dust is carried out indoors. The second Feiyang did not discharge the dust chamber. After a long time, a large amount of stone dust on the filter bag in the dust collector makes the ventilation of the dust collector not smooth, and the negative pressure of the airflow in the shot blasting cleaning room drops sharply. A large amount of dust is flying from the inlet and outlet of the cleaning room, and the air outlet of the fan on the top of the dust collector is dusty gas. There is a big defect in the actual use of the dust collector of such a stone blasting machine.

Therefore, it is necessary to further improve the prior art.

detailed description

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Reference herein to "one embodiment" or "an embodiment" refers to a particular feature, structure or characteristic that can be included in at least one implementation of the present invention. "In one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

Please refer to Figures 1 to 3, Figure 1 is a schematic structural view of the stone shot blasting dust removal device of the present invention; Figure 2 is a schematic side view of Figure 1; Figure 3 is a schematic top view of Figure 1. Wherein, the direction pointed by the downward arrow (the arrow pointing to the dust collection device) in the figure is the direction of dust falling, and the direction pointed by the upward arrow (pointing to the separation fan) is the direction of the purified gas flowing out.

The stone shot blasting dust removal device includes a dust collector chamber body 1, a centrifugal fan 5, a partition 6, a dust bag 2, an air storage bag 3, a pulse valve 4 and a control device.

The dust collector chamber body 1 has an air outlet 13 on the top and a dust collection device 9 on the bottom. The dust collection device 9 has an air inlet 91 on the side and a dust outlet 92 on the bottom. Airflow with dust enters from the airflow inlet 91 . In this embodiment, in order to ensure the filtering efficiency, there are at least two air inlets 91 .

The centrifugal fan 5 is arranged at the air outlet 13 .

The partition plate 6 is arranged in the dust collector chamber body 1 , and the dust collector chamber body 1 is divided into a first chamber 11 and a second chamber 12 by the partition board 6 .

The dust bag 2 is located in the first chamber 11 and the second chamber 12 . In this embodiment, in order to ensure the dust removal effect, there are multiple dust removal cloth bags 2 .

The air storage bag 3 is located above the dust-removing bag 2 and communicated with the dust-removing bag 2 . When there is a lot of dust in the dust bag 2, the pulse valve 4 performs high-pressure soot blowing on the dust in the dust bag 2 through the air storage bag 3, and the dust in the dust bag 2 is collected by the dust. The dust outlet 92 of the device 9 is discharged.

The pulse valve 4 is located above the gas storage bag 3 and communicates with the gas storage bag 3 . The pulse valve 4 performs high-pressure soot blowing on the dust bag 2 through the air storage bag 3 .

The control device is used to control the opening and closing of the first chamber 11 and the second chamber 12 . The control device includes an air cylinder and a gate connected with the air cylinder.

The centrifugal fan works, the control device controls the closing of the first chamber and the opening of the second chamber, and the airflow with dust enters the second chamber from the airflow inlet and passes through the dust bag in the second chamber to filter. When the dust-removing bag in the second chamber accumulates a lot of dust, the second chamber is closed by the control device, the first chamber 11 is opened by the control device, and the airflow with dust enters the first chamber from the airflow inlet 91 The chamber 11 is filtered through the dust-removing bag in the first chamber 11, and at the same time the pulse valve 4 of the second chamber 12 starts to work, and the accumulated dust in the dust-removing bag 2 in the second chamber 12 is compressed by air. Ashes blow down, because the second chamber 12 is sealed and there is no turbulent air flow, the dust will fall out of the dust collector chamber 1 from the dust outlet 92 by its own weight, and the purified gas will flow out from the air outlet 13 through the centrifugal fan 5. When the dust bag 2 in the first chamber 11 accumulates a lot of dust, close the first chamber 11, the control device controls the opening of the second chamber 12, and simultaneously opens the pulse valve 4 of the first chamber 11 , the airflow with dust enters the second chamber 12 from the airflow inlet 91 and is filtered through the dust bag 2 in the second chamber 12, and the compressed air passing through the pulse valve 4 of the first chamber 11 The dust accumulated in the dust bag 2 in the first chamber 11 is blown off, and the purified gas flows out from the air outlet 13 through the centrifugal fan 5 . According to the dust removal requirements of the stone shot blasting machine, the separator 6 is used to separate the dust removal and bag filtration of the dust collector, so that the dust removal effect of the stone shot blasting machine is significantly improved, and the service life of the dust bag is extended. The overall shot blasting equipment works continuously, which increases the working efficiency of the stone shot blasting cleaning machine by 4 times.

The stone shot blasting and dedusting device of the present invention is controlled by compartmental partitions, cylinders and rams, so that the dust collector can be filtered and the work of back blowing and dust removal can be carried out separately. The two airflows will not interfere when the dust collector is filtering and cleaning, so that the filter bag in the dust collector will not be blocked, the dust collector can work normally, the dust removal effect is significantly improved, and the working efficiency is increased by more than 4 times.

The above description has fully disclosed the specific implementation manners of the present invention. It should be pointed out that any changes made by those skilled in the art to the specific embodiments of the present invention will not depart from the scope of the claims of the present invention. Accordingly, the scope of the claims of the present invention is not limited only to the foregoing specific embodiments.
