Abstract
The utility model discloses a multi-stage grinder which is characterized in that at least two stages of grinding devices (17,18,19,20) are arranged on a main shaft (15) which is in transmission connection with a power device; the grinding chambers which corresponds to the grinding devices (10,11,12,13) are trumpet-shaped structures. The small outlet of each trumpet-shaped structure is communicated with the large inlet of the grinding chamber on the next stage; the small outlet of the grinding chamber on the next stage is larger than the small outlet of the grinding chamber on the previous stage; a feeding port is arranged on the grinding chamber (10) on the first stage; the small outlet of the grinding chamber on the last stage is correspondingly communicated with a winnowing chamber (14) which is provided with a discharge hole (2) and a vane (1) which is in transmission connection with the power device. The utility model is a multi-stage grinder which has the advantages of good grinding effect, high grinding efficiency, wide application range, simple structure and is energy-saving and convenient to produce.
Description
Technical field:
The utility model relates to a kind of pulverizer, particularly relates to a kind of multistage grinder.
Technical background:
Pulverizer industry and civilian aspect purposes is widely arranged, industrial and civilian in the middle of play an important role.The pulverizer that extensively adopts has the hammer formula and rolls roll-type at present, adopts single-stage to pulverize mostly, and this pulverizer crushing effect is not ideal enough, and granularity and difficult quality reach requirement, and efficient is low, energy consumption is high, a little less than the production capacity, and narrow application range.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of good crushing effect and crush efficiency height, energy-saving and cost-reducing, applied widely multistage grinder.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: be provided with the two-stage reducing mechanism at least on the main shaft that is in transmission connection with power set, every grade of corresponding respectively pulverizing chamber of reducing mechanism adopts flared structure, the corresponding big mouthful of inlet that is communicated with the next stage pulverizing chamber of its osculum outlet, and the outlet of the osculum of back one-level pulverizing chamber is provided with feeding mouth greater than the osculum outlet of previous stage pulverizing chamber on first order pulverizing chamber; The osculum outlet correspondence of afterbody pulverizing chamber is communicated with the selection by winnowing chamber, the fan blade that the selection by winnowing chamber is provided with discharging opening and is in transmission connection with power set; The main shaft hinge is contained on the body of being made up of pulverizing chamber.
Described reducing mechanism structure is to be packed in the peening hammer support on the main shaft and to cut with scissors the peening hammer that is contained on the peening hammer support.
Described reducing mechanism can be set to 2～10 grades.
Adopt the multistage grinder of technique scheme, at least be provided with the two-stage reducing mechanism on the main shaft that is in transmission connection with power set, every grade of corresponding respectively pulverizing chamber of reducing mechanism adopts flared structure, the corresponding big mouthful of inlet that is communicated with the next stage pulverizing chamber of its osculum outlet, and the outlet of the osculum of back one-level pulverizing chamber is provided with feeding mouth greater than the osculum outlet of previous stage pulverizing chamber on first order pulverizing chamber; The osculum outlet correspondence of afterbody pulverizing chamber is communicated with the selection by winnowing chamber, the fan blade that the selection by winnowing chamber is provided with discharging opening and is in transmission connection with power set, the main shaft hinge is contained on the body of being made up of pulverizing chamber, after starting power set, material enters first order pulverizing chamber from the pulverizer feeding mouth, after crushed, thinner material is through the wind-force swabbing action of the fan blade of selection by winnowing chamber, entering the next stage pulverizing chamber pulverizes again, the osculum outlet of back one-level pulverizing chamber is greater than the osculum outlet of previous stage pulverizing chamber, can effectively guarantee crushing effect, after multistage reducing mechanism is pulverized, material is very thin, after the fan blade effect of selection by winnowing chamber, send discharging opening, reach quality requirement, owing to be to adopt multistage pulverizing and selection by winnowing to send, do not need to assemble grader, the material of the qualified fineness of the disposable effective separation of energy, qualified material can not be stopped in machine, given full play to the efficient of pulverizer, improved the life-span of pulverizer parts, it is stable to go out the thing fineness, do not need to adjust, can process general general powder and super fine, so the utility model is a kind of good crushing effect and crush efficiency height, energy-saving and cost-reducing, applied widely, simple in structure, easily manufactured multistage grinder.
