specific Embodiment 1

[0030] figure 1 , figure 2 , image 3 It shows a cement grinding dust collection and unloading system, which includes a roller press dust collection mechanism 1 and a grinding tail dust collection mechanism 2 arranged in sequence on the new cement production line. The roller press dust collection mechanism 1 includes a double cyclone Dust suction cylinder and main pulse spray bag dust collector 3, the double cyclone dust suction cylinder is arranged at the outlet of the air-powder mixture of the roller press, and the double cyclone dust suction cylinder connects with the main pulse spray bag dust collector 3 through the air duct The feed end is connected, and the dust collection mechanism 2 at the end of the mill includes a secondary pulse spray bag dust collector 4, and the secondary pulse spray bag dust collector 4 is connected with the cement mill through an air duct.

[0031] The roller press dust collection mechanism and the grinding tail dust collection mechanism are ...

specific Embodiment 2

[0033] This embodiment further explains the main pulse spray bag dust collector on the basis of specific embodiment 1, and the main pulse spray bag dust collector 3 is a double series pulse spray bag dust collector.

[0034] The double-series pulse jet bag dust collector is one of the new pulse jet bag dust collectors of FDM. It is based on the original MC type pulse dust collector for reference from the latest technology at home and abroad, and combined with the actual situation of the current pulse dust collector in my country. situation, developed a new generation of bag type dust collector.

[0035] The dust collector adopts the technology of high-pressure (0.4-0.7MPa) large-flow pulse airflow to blow and clean the filter bags one by one. It has the characteristics of large cleaning kinetic energy, high cleaning efficiency, compact structure, and less maintenance workload. The characteristics of line cleaning can make the dust collector run continuously, which overcomes the...

specific Embodiment 3

[0042] This embodiment further explains the structure of the double-series pulse jet bag dust collector on the basis of specific embodiment 2. The double series pulse jet bag dust collector includes bag chambers 5 arranged in sequence from top to bottom , clean air chamber 6 and ash hopper 7, said clean air chamber 6 is provided with row filter bag 8, each top of row filter bag 8 is equipped with a blowing hose, blowing hose and pulse valve and compression The air main pipes are connected, the two ends of the clean air chamber 6 are respectively provided with an air inlet and an air outlet, the outlet of the ash hopper 7 is provided with a grid wheel, and the double-series pulse spray bag dust collector There are two clean air chambers 6 and ash hoppers 7 .

Abstract

The invention discloses a cement mill dust collecting and discharging system. The system comprises a roller press dust collection mechanism and a mill tail dust collection mechanism which are sequentially arranged on a new cement production line, wherein the roller press dust collection mechanism comprises a duplex cyclone dust collection cylinder and a main pulse spray bag dust collector; the duplex cyclone dust collection cylinder is arranged at a gas-powder mixture outlet of the roller press; the duplex cyclone dust collection cylinder is connected with the feeding end of the main pulse spray bag dust collector through an air pipe; the mill tail dust collection mechanism comprises a secondary pulse spray bag dust collector; and the secondary pulse spray bag dust collector is connected with the cement mill through an air pipe. The problem that an existing dust collection system is poor in dust collection effect during cement production is solved.

Description

technical field [0001] The invention relates to the field of cement clean production, in particular to a cement grinding dust collecting and unloading system. Background technique [0002] In the process of cement production, a large amount of dust will be generated when processing materials. If this part of dust is not handled properly, it will cause serious pollution to the environment. However, the design of the dust collection system during cement production in the prior art is not perfect. , It often occurs that some key parts of the dust collection mechanism cannot perfectly complete the dust collection task. Contents of the invention [0003] The purpose of the present invention is to provide a cement grinding dust collection and ash discharge system, which solves the problem of poor dust collection effect of the existing dust collection system during cement production. [0004] In order to solve the above-mentioned technical problems, the present invention ado...
