Embodiment Construction

[0017] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0018] See figure 1 , is a schematic diagram of the structure of the embodiment of the full negative pressure powder processing system of the present invention. The jaw crusher 1 crushes the material to a certain particle size, and the material is sent to the hopper 3 through the elevator 2. The material is quantitatively and continuously sent to the main machine 8 of the mill for grinding. The main machine 8 of the mill is equipped with a differential pressure detection device 7. The main machine 8 of the mill maintains a negative pressure state with a pressure difference of 15-20 mbar. The pressure difference value of the main machine 8 of the powder mill controls the feeding amount of the rotary tangential feeder 4, and the ground powder is classified by the classifier 9 placed on the main machine 8 of the mill, and the powder with qualified f...

Abstract

The invention relates to a full-negative-pressure powder processing system, which is characterized by comprising a jaw crusher, an elevator, a pulverizing mill, a high-pressure box type pulse collector, a buffering air suction hopper, an accelerating pipe and a finished product storage bin, wherein the jaw crusher is in process connection with the elevator, the hopper, a rotary tangent feeder and a host machine of the pulverizing mill; the dust outlet of the high-pressure box type pulse collector is connected with the accelerating pipe through a rotary unloader I, the buffering air suction hopper and a rotary feeder in sequence; and the dust outlet of the finished product storage bin is provided with a manual valve and a rotary unloader II in sequence. Compared with the prior art, the invention has the advantages: (1) air current of the entire system fully runs under the negative pressure 15-25 mbar, so that the problem of dust pollution is solved, and the operating environment and the ambient environment are improved greatly; (2) the air current is uniform and smooth, so that the vibration of a unit is reduced, and the energy consumption is lowered; and (3) the yield of the pulverizing mill is increased from 4.5 t/h to 5.5 t/h, and the machine hour yield is increased by 23 percent.

Description

technical field [0001] The invention relates to the field of powder processing, in particular to a full negative pressure powder processing system. Background technique [0002] At present, the powder processing system adopts the pulverizer system, and the air flow is closed-circuit. During the operation of the unit, the dust leakage is serious, which affects the health of the workers and pollutes the surrounding environment; and when the unit is running, the vibration noise of the machine is large and energy consumption Large, low output, serious waste of raw materials. See attached figure 2 , is the flow chart of the powder processing system in the prior art. The jaw crusher (32) crushes the raw material to a certain size, and the hoist (33) sends the crushed material to the hopper of the mill, and the material is discharged by rotation. The device (34) continuously and quantitatively sends the material to the main machine (36) of the mill for grinding. The annular bello...
