Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a dust collecting and air supply device for a raw material homogenizing bin. Background Art

[0002] Cement raw meal is stored in the homogenization silo;

[0003] In the process of homogenizing raw materials in the homogenizing warehouse, a lot of dust-containing gas will be generated. A large amount of dust-containing gas overflows and pollutes the environment, causing large dust exhaust losses. For this reason, a bag dust removal structure is generally used for dust collection.

[0004] In the current bag-type dust removal structure, the bags are easily deformed under the suction of negative pressure and the impact of dust-laden gas, resulting in a reduction in the ventilation area of the bags. In addition, the particles attached to the outer surface of the bags cannot be processed in time, resulting in a reduction in the ventilation volume of the bags.

[0005] Therefore, we propose a dust collection and air supply device for a raw meal homogenization silo to solve the existing problems. Utility Model Content

[0006] The purpose of the utility model is to solve the problems existing in the background technology and to provide a dust collecting and air supply device for a raw material homogenizing silo.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a dust collection and air supply device for a raw material homogenization storage, comprising a storage body, a tank body and a filter bag, the storage body being provided with a storage opening, the tank body being provided on the storage opening, the tank body and the storage opening being interconnected, a partition being provided at the upper end of the interior of the tank body, the filter bags being equidistantly provided on the partition, the internal support of the filter bag being provided with a wire rack, and a vibration motor being fixed on the wire rack.

[0008] Preferably, the lower surface of the tank body is provided with supporting feet, and the bottom ends of the four supporting feet are fixed to the outer wall of the storage opening.

[0009] Preferably, the partition is provided with circular holes, and the upper end of each filter bag is fixed on the circular hole.

[0010] Preferably, a sealing cover is installed at the top opening of the tank body, and a sealing gasket is provided at the contact position between the sealing cover and the tank body;

[0011] Recoil heads are equidistantly arranged on the cover, and each recoil head is equipped with a recoil pipe. The position of each recoil pipe corresponds to the position of each filter bag.

[0012] Preferably, rubber rings are mounted on the upper surface of the partition via bolts, and the top ends of the steel wire racks are fixed on the rubber rings.

[0013] Preferably, a suction head is provided at the upper end of the tank body, a suction pipe is installed on the suction head, a pump body is provided on the upper surface of the storage body, and the suction end of the pump body is communicated with the suction pipe.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] During the use of the dust collecting and air supply device for the raw meal homogenizing silo, when the raw meal homogenizing silo is homogenized, an external power supply is connected to the pump body to make the pump body work to suck the inside of the tank body through the suction pipe. At this time, the dust-laden gas goes up into the tank body, is filtered by the filter bag, and the particles are retained on the outer surface of the filter bag. The filtered air is discharged through the discharge end of the pump body.

[0016] During this process, under the action of negative pressure and the impact of dust-laden gas, the filter bag clings to the wire rack, which limits the filter bag from significant deformation. At the same time, the vibration motor drives the wire rack to vibrate, thereby driving the filter bag to vibrate, which can shake off particles attached to the outer surface of the filter bag.

[0017] The utility model avoids deformation of the cloth bag under the suction of negative pressure and the impact of dust-laden gas, maintains the ventilation area of the cloth bag, and can promptly clean particles attached to the outer surface of the cloth bag in conjunction with the vibration action, thereby maintaining the ventilation volume of the cloth bag.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figures 1-4 As shown, the utility model proposes a dust collection and air supply device for a raw material homogenization storage, comprising a storage body 1, a tank body 4 and a filter bag 14. The storage body 1 is provided with a storage opening 2, the tank body 4 is provided on the storage opening 2, the tank body 4 and the storage opening 2 are interconnected, a partition 11 is provided at the upper end of the interior of the tank body 4, and filter bags 14 are equidistantly provided on the partition 11. The internal support of the filter bag 14 is provided with a wire rack 13, and a vibration motor 12 is fixed on the wire rack 13.

[0027] Based on Example 1:

[0028] During the use of the dust collecting and air supply device for the raw meal homogenizing silo of the present invention, when the raw meal homogenizing silo is homogenized, an external power supply is connected to the pump body 9 to operate and suck the interior of the tank body 4 through the suction pipe 8. At this time, the dust-laden gas ascends into the tank body 4 and is filtered by the filter bag 14. The particles are retained on the outer surface of the filter bag 14, and the filtered air is discharged through the discharge end of the pump body 9.

[0029] During this process, under the action of negative pressure and the impact of dust-laden gas, the filter bag 14 is tightly attached to the wire rack 13. The wire rack 13 can limit the filter bag 14 from producing a large amount of deformation. At the same time, the vibration motor 12 drives the wire rack 13 to vibrate, thereby driving the filter bag 14 to vibrate, which can shake off the particles attached to the outer surface of the filter bag 14. The shaken-off particles re-enter the homogenization storage.
