Description

Technical Field

[0001] The utility model relates to the technical field of dust removal in cement plants, in particular to a dust removal mechanism. Background Art

[0002] Cement plants have a lot of dust pollution, mainly because the environmental pollutants in cement plants are dust and nitrogen oxides produced by fuel combustion. The sources of dust are mainly unorganized emissions from raw materials and fuel yards and emissions from various production nodes. In order to improve the environmental problems caused by excessive dust, almost all cement plants are equipped with cement bags for dust prevention. These bags capture dust particles generated during the production process through physical filtration, thereby reducing dust emissions.

[0003] However, when the bag is used for dust prevention, a large amount of dust adsorbed on the outer wall needs to be cleaned by recoil air. The degree of cleaning is greatly affected by the recoil air pressure. At this time, in order to ensure cleanliness, the recoil air pressure needs to be increased, which leads to an increase in the company's investment cost. Therefore, a dust removal mechanism is needed to solve the above problem. Utility Model Content

[0004] The utility model aims to provide a dust removal mechanism which has the advantage of recoil cleaning the surface of the bag without increasing the recoil gas pressure, thereby solving the problem that the cleanliness of the bag is greatly affected by the recoil gas pressure and causes increased use costs for enterprises.

[0005] To achieve the above object, the utility model provides the following technical solutions: a dust removal mechanism, including a dust removal cloth sleeve, an exhaust groove and a connecting ring, a dust removal cloth bag is fixedly installed below the dust removal cloth sleeve through a sealing sleeve, and also includes a connecting pipe;

[0006] The connecting pipe passes through the dust removal cloth sleeve and the dust removal cloth bag;

[0007] Among them, electric telescopic rods are fixedly installed on the connecting pipe in a circular array;

[0008] Wherein, one end of the electric telescopic rod away from the connecting pipe is fixedly connected to the inner side of the sealing sleeve.

[0009] When using a dust removal mechanism in the technical solution, the dust collection cloth cover and the dust collection bag are connected and installed through the sealing sleeve, and the connecting pipe is inserted from the top of the dust collection cloth cover, and the electric telescopic rod is fixedly installed on the connecting pipe through the connecting ring, and the end of the electric telescopic rod facing away from the connecting ring is fixedly connected to the inner side of the sealing sleeve. At the same time, the equipment is installed on the inner side of the dust removal mechanism through the mounting plate, and the top of the connecting pipe is passed through the reserved hole and fixedly connected to the pulse valve. When the dust prevention operation is performed, the electric telescopic rod contracts to pull the sealing sleeve inward, thereby causing the dust collection cloth cover and the dust collection bag to retract inward, thereby reducing the surface gap, so as to perform the dust prevention operation. When the dust collection cloth cover and the dust collection bag need to be dusted and the surface cleaned, the electric telescopic rod is extended, and the dust collection cloth cover and the dust collection bag are opened under the action of the sealing sleeve, thereby increasing the surface gap, so that the dust collection cloth cover and the dust collection bag can be subjected to surface dust removal operations under a relatively small gas pressure.

[0010] Preferably, the top of the dust removal cloth sleeve is embedded in the second connecting sleeve, the top of the second connecting sleeve is connected to the exhaust groove, and a mounting plate is welded to the bottom of the outer side of the second connecting sleeve.

[0011] By embedding the top of the dust removal cloth sleeve into the second connecting sleeve and connecting the top of the second connecting sleeve with the exhaust groove, the gas discharge is facilitated, and a mounting plate is welded on the bottom of the outer side of the second connecting sleeve, so that the equipment can be installed on the inner side of the dust removal mechanism through the mounting plate.

[0012] Preferably, a reserved hole is opened at the top of the exhaust groove, one side of the exhaust groove is closed, and the other end of the exhaust groove is open and provided with a flange.

[0013] By closing one side of the exhaust groove and opening the other end of the exhaust groove and providing a flange, it is convenient to connect and install the exhaust groove with the exhaust channel.

[0014] Preferably, the sealing sleeve is designed with a soft rubber material, and the dust removal cloth sleeve and the dust removal cloth bag are respectively sewn on the inner side of the sealing sleeve on opposite sides.

[0015] The sealing sleeve is designed with a soft rubber material so that the sealing sleeve has better toughness, and the dust cover and the dust bag are sewn on the inner side of the sealing sleeve respectively on the opposite sides, so that the dust cover and the dust bag can be expanded and stretched on the opposite sides through the sealing sleeve.

[0016] Preferably, the bottom of the dust removal bag is covered with a first connecting sleeve, and the first connecting sleeve is designed with stainless steel material and has pores on the surface.

[0017] By covering the bottom of the dust bag with a first connecting sleeve, the bottom of the dust bag is positioned by the first connecting sleeve and it is ensured that the dust bag will not shrink to a large extent during dust prevention operations. At the same time, the first connecting sleeve is designed with stainless steel material and has pores on the surface, so that the gas can pass through the first connecting sleeve and circulate through the dust bag.

[0018] Preferably, the top of the connecting pipe passes through a reserved hole and is provided with a flange and is connected and installed with the pulse valve, and exhaust holes are opened on the connecting pipe inside the dust collection cloth sleeve and the dust collection cloth bag.

[0019] By passing the top of the connecting pipe through a reserved hole and providing a flange and connecting it with the pulse valve, when the pulse valve is opened, high-pressure gas can enter the connecting pipe. Exhaust holes are opened on the connecting pipe on the inner side of the dust cover and the dust bag, so that the high-pressure gas can be discharged through the exhaust holes and impact the dust cover and the dust bag.

[0020] Preferably, the number of the electric telescopic rods is three, and opposite ends of the three electric telescopic rods are respectively fixedly connected to the outer wall of the connecting ring, and the connecting ring is fixedly mounted on the connecting pipe.

A hole is left to pass through and is fixedly connected to the pulse valve. When performing dust prevention operations, the electric telescopic rod contracts to pull the sealing sleeve inward, thereby causing the dust cover and dust bag to shrink inward, thereby reducing surface gaps and performing dust prevention operations. When the dust cover and dust bag need to be dusted and the surface cleaned, the electric telescopic rod extends, and the dust cover and dust bag are opened under the action of the sealing sleeve, thereby increasing surface gaps, so that the dust cover and dust bag can be dusted on the surface under a relatively small gas pressure, thereby achieving the effect of recoil cleaning the bag surface without increasing the recoil gas pressure.
