Abstract

The utility model relates to a feed crushing machine, in particular to an integrated concentric double-impeller dustproof crusher which includes a motor, a shell of the crusher, a cover, a crushing wind disk, a material suction air return pipe which is provided with a material inlet pipe, an effort material feeding pipe and a powder/gas separating cylinder whose upper cover is provided with a hop-pocket. The material suction air return pipe is separately connected with the crusher and the powder/gas separating cylinder; the effort material feeding pipe is separately connected with the cover of the crusher and the powder/gas separating cylinder to form internal and external concentric space; a half-tooth half-screen clapboard and a blast impeller are separately arranged on the exterior of the crushing wind disk in the shell of the crusher; a transmission wheel which is concentrically pierced with the half-tooth half-screen clapboard is separately connected with the crushing wind disk and the blast impeller and is connected with the rotation shaft of the motor. The utility model has the advantages of small dust pollution, energy-saving, low device cost, small space occupation, preventing blocking of the powder feeding and suction material, and high yield, and is suitable to be applicable for a feed processing enterprise.

Description

The concentric bilobed wheel return air of one dust-free pulverizing mill

One. technical field

The utility model relates to a kind of feed grinder tool, and the concentric bilobed wheel return air of especially a kind of one dust-free pulverizing mill is suitable for feed processing enterprise and uses.

Two. background technology

Feed processing enterprise often needs pellets such as corn, dregs of beans are processed into powder, so extensive use feed grinder tool.Feed grinder kind in the market is more, mechanical " 40 types; 50 type feed grinders " produced with Jiangxi Red Star machinery plant are representative, this machine need be joined preposition raw material lifting device and be connected the feed grinder coaxial with air blast with the belt pair, feed grinder and air blast separately are arranged side by side, connect feed grinder and air blast respectively with a bend pipe, because the different storehouses of its feed grinder with air blast, the bend pipe dead angle is very easily stopped up, powder gas cylinder is uncovered, so there is the equipment complexity, it is big to take up room, problems such as power consumption and even serious dust pollution of the environment.

For addressing the above problem, a kind of " the dustless feed grinder of circulation return air " recorded and narrated by China formerly patent application 200620080060.X, comprise: motor, pulverizer, the strength feed pipe, powder gas cylinder is formed, connect gas powder cylinder loam cake and pulverizer suction tube with a backwind tube, form a circulation strength loop with the strength feed pipe that is connected gas powder cylinder and pulverizer, material is entered by electric motor driven pulverizer pulverizing back from suction tube enter gas powder cylinder along the strength feed pipe, most of powder falls to out funnel in the gravity effect, and the fraction powder forms when rising to gas powder cylinder loam cake under the strength effect that turbulent powder falls and air-flow is carried powder in micro-amount secretly and is back to the pulverizer suction tube through backwind tube and recycles said process with mixing of materials.It can reduce dust pollution, energy-conservation, reduce equipment manufacturing cost and minimizing takes up room, but pulverize the wind dish owing to only be provided with one in its feed grinder, so powder feeding and suction amount are subjected to the blanking quantitative limitation, powder feeding and suction are stopped up easily, output is limited.

Three. summary of the invention

Task of the present utility model provides a kind of improved feed grinder tool, it both can form a circulation strength loop, reduced dust pollution, energy-conservation, reduce equipment manufacturing cost and minimizing takes up room, can prevent that again powder feeding and suction from stopping up, improving output.

For finishing this task, the utility model carries out in the following way:

It comprises: the casing of motor, pulverizer, cover cap, pulverizing wind dish, the suction backwind tube that is provided with feed pipe, strength feed pipe, on be covered with cloth bag powder gas cylinder form, the suction backwind tube connect pulverizer respectively with powder gas cylinder, the strength feed pipe connects the cover cap and the powder gas cylinder of pulverizer respectively, form a circulation strength loop, pulverizing wind dish periphery in the casing of pulverizer is respectively equipped with half tooth and partly sieves a dividing plate and a blasting vane wheel, forms inside and outside two spaces with one heart; Wear a drive that half tooth partly sieves dividing plate with one heart and connect respectively and pulverize the wind dish with blasting vane wheel and be connected motor rotary shaft, pulverizing wind dish and blasting vane wheel can with motor rotary shaft run-in synchronism.

Half set tooth partly sieves dividing plate towards strength feed pipe central diameter separation structure, and half is for pulverizing dental lamina, and half is the powder delivery filter screen, can cooperate pulverizing, powder delivery with the moving hammer of pulverizing the wind dish.

The utility model has been owing to adopted above technical scheme, except reduce dust pollution, energy-conservation, reduce the characteristics such as equipment manufacturing cost and minimizing take up room, also have and can prevent powder feeding and suction obstruction, output advantages of higher.

Four. description of drawings

The concrete structure of utility model is provided by the following drawings.

Fig. 1 is according to the concentric bilobed wheel return air of the one dust-free pulverizing mill perspective view that the utility model proposes.

To be described in further detail the concentric bilobed wheel return air of the one that the utility model proposes dust-free pulverizing mill below in conjunction with accompanying drawing.

Five. the specific embodiment

As shown in Figure 1, the utility model comprises: the casing 1 of motor 4, pulverizer, cover cap 9, pulverize wind dish 6, be provided with feed pipe 7 suction backwind tube 8, strength feed pipe 10, on be covered with cloth bag 11 powder gas cylinder 12 form, suction backwind tube 8 connect pulverizer respectively with powder gas cylinder 12, strength feed pipe 10 connects the cover cap 9 and powder gas cylinder 12 of pulverizer respectively, form a circulation strength loop, pulverizing wind dish 6 peripheries in the casing 1 of pulverizer are respectively equipped with half tooth and partly sieve a dividing plate 2 and a blasting vane wheel 3, form inside and outside two spaces with one heart; Wearing a drive 5 that half tooth partly sieves dividing plate 2 with one heart connects respectively and pulverizes wind dish 6 with blasting vane wheel 3 and be connected motor 4 rotating shafts.

With reference to Fig. 2, pulverizing wind dish 6 can partly sieve dividing plate 2 around half tooth with blasting vane wheel 3 and be driven run-in synchronism along the direction of arrow by motor 4 rotating shafts.

With reference to Fig. 3, described half tooth partly sieve dividing plate 2 at double-head arrow towards strength feed pipe 10 central diameter separation structures, half is for pulverizing dental lamina, half be the powder delivery filter screen, can cooperate pulverizing, powder delivery with the moving hammer of pulverizing wind dish 6, single arrow is a feedstock direction.
