Description

Technical Field

[0001] The invention relates to the technical field of talcum powder production, in particular to a talcum powder production dust removal process with high energy saving and environmental protection. Background Art

[0002] Talc has excellent physical and chemical properties such as lubricity, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good hiding power, softness, good gloss, and strong adsorption. Since the crystal structure of talc is layered, it has a tendency to split into scales and special lubricity. Dust emissions will be generated in the process of producing talc, which contains a large amount of talc dust. Direct emissions will cause serious pollution and loss of talc products in the exhaust gas. Usually, talc tail gas dust removal equipment uses other industrial dust removal and recovery devices, but the dust treatment is not thorough, and the internal structure is often blocked during the treatment process, and an effective circulation dust removal process cannot be achieved. Dust emissions to the outdoors will also cause harm to the environment and human health, and cannot meet existing environmental protection requirements. Summary of the invention

[0003] The purpose of the present invention is to provide a talcum powder production dust removal process with high energy saving and environmental protection, so as to solve the problems raised in the above background technology.

First, dust suction pipes are installed on the upper and lower sides of the talcum powder production equipment, and the two dust suction pipes correspond to the feed inlet and the discharge port respectively; S2. Connect one end of the two dust collection pipes to the lower air inlet pipe of the external bag dust collector, use the bag dust removal method to remove dust, and use the dust removal fan to transport the dust generated by the production and processing of talcum powder to the filtering equipment; S3, then using the filter screen in the filtering device to filter the particle impurities in the dust, and after the treatment, using the cleaning mechanism to clean the particles adhered to the surface of the filter screen to avoid clogging of the filter screen holes; S4. The dust filtered by the filtering equipment enters the ash hopper through the guide plate from the lower air inlet duct. Due to the collision of the guide plate and the reduction of gas velocity, the coarse dust will fall into the ash hopper, and the remaining fine dust will enter the filter bag chamber with the gas and complete the subsequent filtering treatment, thereby achieving the purpose of cleaning the dust generated by talcum powder production.

[0005] Preferably, the upper and lower dust suction pipes installed in step S1 are fixed by welding via a positioning bracket, and a sealing ring is installed externally when the dust suction pipe is connected to the lower air intake pipe, and it is ensured that there is no leakage at the connection.

[0006] Preferably, in step S3, the mesh size of the filter screen is 0.09 mm and the mesh number is 170 meshes.

[0007] Preferably, during the dust removal process in step S3, a cleaning brush is used to reciprocately clean the surface of the filter screen, the length of the cleaning brush is the same as the width of the filter screen, and the cleaned particles are collected by a collecting bucket below.

[0008] Preferably, the dust transported to the filtering device is processed for no less than 10 minutes, and the internal filter screen is a double-layer structure.

[0009] Preferably, the bag dust collector is installed on one side of the talcum powder production equipment, and a certain distance is left between the bag dust collector and the talcum powder production equipment, and the talcum powder production equipment needs to maintain balance after being installed on the ground.

[0010] Preferably, the fan in step S2 is a dust blower.

[0011] Preferably, the dust suction pipes installed on the upper and lower sides must ensure that they do not affect the feeding and discharging of materials, and the dust suction pipes use steel wire hoses.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can quickly absorb the dust generated by the feed port and the discharge port by effectively connecting the bag dust collector with the talcum powder production equipment to avoid dust residue. At the same time, after the dust is absorbed, the large particles contained in the dust are filtered by the filtering equipment to prevent the inside of the bag dust collector from being blocked. When cleaning the particles, the cleaned particles can be collected and reused to avoid waste. The use of the bag dust collector to process the dust entering the interior can improve the processing quality, thereby achieving the purpose of effectively processing the dust generated by the production and processing of talcum powder and avoiding harm to the environment and human body.
