Abstract
The utility model discloses a kind of noise extra fine heavy calcium carbonate powder crushing device, comprise material storing box, material conveying device, pulverizer, clasfficiator, dust cleaning case and air-introduced machine, it is characterized in that the clasfficiator of pulverizer and top is arranged in silencing room, described silencing room is closed space and leaves the installing hole of feed pipe and discharge nozzle; The discharge pipe of air-introduced machine is provided with silencer.Noise extra fine heavy calcium carbonate powder crushing device of the present utility model, significantly can reduce noise in production and application process, and noise decrease is on the impact of workman and neighbouring resident.
Description
Technical field
The utility model relates to a kind of reducing mechanism, particularly relates to noise extra fine heavy calcium carbonate powder crushing device.
Background technology
Powdered whiting is due to cheap, chemical purity is high, inertia is large, not easily chemical reaction, Heat stability is good, whiteness is high, oil absorbency is low, the low wearing valve of hardness is little, nontoxic, tasteless, odorless, many merits such as good dispersion and widely using in the industry, and for the production of the reducing mechanism of superfine heavy calcium carbonate, pulverizer wherein, the main machine rotating speeds such as air-introduced machine are high, power is large, the noise produced is stronger, through test, the noise tested near pulverizer is up to more than 100 decibels, all can affect for the workman of factory and neighbouring resident.
Summary of the invention
The purpose of this utility model is to provide noise extra fine heavy calcium carbonate powder crushing device, solves the problem that above-mentioned dicalcium powder crushing device noise is large.
The utility model is achieved like this: noise extra fine heavy calcium carbonate powder crushing device, comprise material storing box, material conveying device, pulverizer, clasfficiator, dust cleaning case and air-introduced machine, it is characterized in that the clasfficiator of pulverizer and top is arranged in silencing room, described silencing room is closed space and leaves the installing hole of feed pipe and discharge nozzle; The discharge pipe of air-introduced machine is provided with silencer.
Raw material loads material storing box, be transported to the charging aperture of pulverizer by material conveying device from the opening below material storing box, enter pulverizer to pulverize, the extra fine heavy calcium carbonate powder end of separating through clasfficiator again, enter dust cleaning case, discharging after sedimentation in dust cleaning case, flue gas is drawn by air-introduced machine and is discharged through exhaust outlet.In the extra fine heavy calcium carbonate powder crushing device course of work, pulverizer, clasfficiator and air-introduced machine rotating speed is high, power is large, for main noise source, the utility model exactly by installing silencing room on pulverizer and clasfficiator, and the discharge pipe of air-introduced machine fixes a silencer stress release treatment.
The beneficial effects of the utility model are noise extra fine heavy calcium carbonate powder crushing devices of the present utility model, significantly can reduce noise in production and application process, and noise decrease is on the impact of workman and neighbouring resident.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In the drawings, 1, pulverizer 2, clasfficiator 3, material storing box 4, material conveying device 5, silencing room 6, dust cleaning case 7, air-introduced machine 8, silencer.
Detailed description of the invention
As shown in Figure 1, noise extra fine heavy calcium carbonate powder crushing device of the present utility model, comprise material storing box (3), material conveying device (4), pulverizer (1), clasfficiator (2), dust cleaning case (6) and air-introduced machine (7), it is characterized in that the clasfficiator (2) of pulverizer (1) and top is arranged in silencing room (5), described silencing room (5) is closed space and leaves the installing hole of feed pipe and discharge nozzle; The discharge pipe of air-introduced machine (7) is provided with silencer (8).
Raw material loads material storing box (3), the charging aperture that material conveying device (4) is transported to pulverizer (1) is passed through from the opening of material storing box (3) below, enter pulverizer (1) to pulverize, the extra fine heavy calcium carbonate powder end of separating through clasfficiator (2) again, enter dust cleaning case (6), discharging after sedimentation in dust cleaning case (6), flue gas is drawn by air-introduced machine (7) and is discharged through exhaust outlet.In the extra fine heavy calcium carbonate powder crushing device course of work, pulverizer (1), clasfficiator (2) and air-introduced machine (7) rotating speed is high, power is large, for main noise source, the utility model exactly by installing silencing room (5) on pulverizer (1) and clasfficiator (2), and the discharge pipe of air-introduced machine (7) fixes a silencer (8) carry out stress release treatment.
