FIG. 2 is a schematic view of an embodiment of the dust extraction apparatus of FIG. 1.

Detailed Description

The present invention will be described in detail below with reference to embodiments shown in the drawings. The embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to the embodiments are included in the scope of the present invention.

In the following, this solution is described by means of the schematic representation of the figure, as an embodiment shown in fig. 1 and 2.

The bulk storage tank of the utility model is provided with a material storage tank for storing materials including cement, commercial mortar, concrete and other materials and a dust removal device 1;

the upper portion of the tank body 2 of the material storage tank is provided with a pressure relief opening communicated with the material cavity of the tank body 2, and the pressure relief opening is communicated with the air inlet and used for exhausting when materials are filled. The lower part of the tank body 2 is provided with a discharge hole which is communicated with the material cavity of the tank body 2.

The dust removing device 1 can be arranged at the upper part of the tank body of the material storage tank when in use, and can be arranged at other positions by communicating with an air supply pipeline, and the arrangement is only required to ensure that the air can be smoothly exhausted when filling.

As an example, the dust removing apparatus 1 has an outer filter bag 11 and at least one inner filter bag disposed inside the outer filter bag 11, here, an inner filter bag is taken as an example, and is configured such that the outer filter bag 11 is disposed outside the inner filter bag, and the inner and outer filter bags form two filter intercepting layers on a filter wind path. The openings of the inner and outer filter bags face the filtering direction. At the moment, the air inlet is communicated with the air outlet or the exhaust pipeline on the storage tank body, the air inlet is connected to the openings of the two layers of filter bags arranged inside and outside, so that air flow containing materials to be filtered is conveyed into the bags during filtering, the air flow directly collides against the inner wall of the inner filter bag and is buffered and intercepted for the first time, the interception plays a role in intercepting the air flow and intercepts most of the materials, and then the air flow passes through the outer filter bag 11, at the moment, the impact of the air flow on the outer filter bag 11 can be obviously reduced, and the outer filter bag 11 also reduces the chances of further impact and abrasion of the materials.

In the above-mentioned solution, the size of the inner filter bag may be equal to or slightly larger than that of the outer filter bag 11, and since there are only those inner filter bags that are sleeved with each other, the filter bag sleeved in the rest of the filter bags will be partially folded in the filter bag at the outer side thereof, such as the bottom of the bag. Because of the filter bag in the dust-catcher 1, the folded portion is opposite to the air flow, so the folded portion can enhance the required buffer function and can also enhance the ability to resist the abrasion of the materials in the air flow to the filter bag, thereby undoubtedly more effectively enhancing the service life of the dust-catcher 1. Even the replacement is not needed in the whole construction period, and the existing products need to be replaced after being used for a period of time, such as about 2 months, particularly the damage condition of the filter bag is seen, and generally the filter bag needs to be replaced for a plurality of times in one construction period.

In the above solution, since the inner filter bag directly receiving the impact belongs to a vulnerable fitting, for maintenance convenience, a spare inner filter bag can be arranged near the inner filter bag, for example, beside the innermost inner filter bag, so as to perform quick replacement during maintenance. Of course, the position of the spare inner filter bag can be arranged in the outer filter bag 11 or near the outer side of the outer filter bag 11, so that the spare inner filter bag is convenient to take. Of course, when the standby inner filter bag is arranged, the opening direction of the standby inner filter bag can be consistent with the opening direction of other bags and fixed; of course, the folding device can be placed at other positions in other folding modes.

In the above solution, in order to improve the safety of the cloth bag filter device, a shell 12 for providing protection may be disposed outside the cloth bag filter device, and the cloth bag of the cloth bag filter device may be placed in the shell 12. In this case, the housing 12 may be provided with an opening near the inlet for connecting the filter bag, which may be used to connect the dust collector 1 to the storage tank. The connection position can also be provided with a sealing structure such as a sealing strip and the like for realizing sealing.

In the above solution, the housing 12 may also be provided with a window 13, and the position of this window 13 may be provided on the side wall or the top wall, and this window 13 may be used for maintenance replacement of the filter bag and also for exhaust. Of course, in general, this window 13 is closed by a door provided to keep the window 13 closed in normal operation. And the door may be opened when maintenance or venting assistance is required.

In the above solution, the housing 12 is further provided with an exhaust port for exhausting air upwards, and the arrangement is such that the buffered and filtered air is exhausted through the exhaust port. Since the air outlet is opened upwards, a rain-proof device for preventing wind and rain can be arranged above the air outlet, the rain-proof device is at least provided with a surface 14 which can shield the air outlet and prevent rain from entering, the surface 14 can be integrated or combined by a plurality of pieces, and the shape can be like a umbrella surface or a plurality of roof tiles. The whole body can be in a plane shape, a conical shape, an inclined plane shape and the like.

In the above solution, a fixing rod for supporting and fixing is further provided between the surface 14 of the rain protection device and the air outlet, and the fixing rod and the air outlet may be connected in a fixed connection manner such as welding, or in a movable connection manner such as screwing or riveting. The fixing rod functions as a limiting surface 14, effectively shields the air outlet, and can support the surface 14, so that a gap or a clearance for effectively dispersing air flow is formed between the air outlet and the surface 14, and the form of the clearance is not limited.

When the material storage tank is filled with materials on the site, a large amount of materials in the material storage tank are discharged along with discharged airflow, and dust removal can be realized after the materials pass through the filter bag.
