Description

TECHNICAL FIELD

[0001] The application relates to the technical field of dust collectors, in particular to a pulse dust collector for calcium carbonate grinding processing. BACKGROUND

[0002] Calcium carbonate is an important inorganic non-metallic material and is widely applied to multiple industries such as building materials, chemical industry, plastics, papermaking, paint and rubber. In the production and processing flow of calcium carbonate, the grinding process is a key link for determining the fineness, purity and application performance of products. Whether it is a Raymond mill, a ball mill or a vertical mill, a large amount of calcium carbonate dust will be generated during the grinding and refinement of calcium carbonate ore or semi-finished products. If these dusts are not effectively treated in time, on the one hand, the dusts will diffuse in the production workshop and the surrounding environment, which will seriously endanger the respiratory health of the operating personnel; on the other hand, the dusts contain a large amount of recyclable calcium carbonate products, and direct emission will cause waste of raw materials and increase the production cost of enterprises, so a pulse dust collector needs to be used to collect and treat the dust generated during grinding.

[0003] The prior art (Chinese Patent No. CN216677471U, Publication Date: 2022-06-07) discloses a pulse dust collector for calcium carbonate grinding, including a dust collection box. A suction pipe is provided on one side of the dust collection box, an air outlet pipe is provided on the other side, and a dust discharge pipe is provided at the bottom of the dust collection box. A cover plate is installed on the front surface of the dust collection box via a hinge. A filter mechanism is installed inside the dust collection box, and a fixed bracket is fixedly connected to the surface of the dust collection box. The fixed bracket is connected to a lifting mechanism. This invention uses a motor to drive a threaded rod to rotate. Because the threaded rod engages and penetrates the fixed bracket, it drives the dust collection box to move... The device features vertical lifting for easy loading and handling of dust. Opening the cover allows for easy replacement of filter plates and filter elements via slide rails one and two, enabling reusability and improving maintenance efficiency. Existing technology (Chinese patent publication number CN218687443U, published on 2023-03-24) discloses a dust removal device for calcium carbonate production, belonging to the field of calcium carbonate dust removal technology. It includes: a base plate and a housing mounted on top of the base plate; a first telescopic rod is connected to the top of the housing, extending into the housing; a scraper is connected to one end of the first telescopic rod extending into the housing; and a mounting box is connected to the side of the housing. The side of the mounting box is welded with an air suction pipe for collecting calcium carbonate dust generated during the grinding process of the grinding machine in the production of calcium carbonate. This dust removal device for calcium carbonate production prevents the overflow of uncollected dust from the dust removal device, while the filter plate is easy to disassemble and install without affecting the continued operation of the dust removal device. It also facilitates the collection of dust, and the filter plate and collection tank are easy to install and disassemble. The prior art (Chinese patent announcement number: CN216395695U, publication date: 2022-04-29) discloses a dust removal device for calcium carbonate processing, including a flue gas inlet pipe, a treatment tank installed at the outlet end of the flue gas inlet pipe, an outlet pipe installed on the outside of the treatment tank, and a treatment tank on the inside. The system incorporates an adsorption mesh, with a diversion cover installed at the top. A flow-gathering plate is connected to the bottom of the treatment tank, and a water outlet pipe is installed at the bottom of the flow-gathering plate. A diversion chamber is located inside the diversion cover, and a water guide hole is located at the bottom of the diversion cover. Two inlet pipes are symmetrically connected to the top of the diversion cover, allowing external water to enter the inner side of the diversion cover. The water inlet chamber and water guide hole flush away the dust adsorbed on the surface of the adsorption mesh, thereby discharging wastewater through the flow-gathering plate and the water outlet pipe. Repeated cleaning of the adsorption mesh reduces the frequency of filter replacement and maintenance, minimizing time wastage and ultimately reducing treatment costs. This improves the efficiency of calcium carbonate production and lowers manufacturing costs.
