Description

TECHNICAL FIELD

[0001] The present application relates to the field of shearing type pulverizer, in particular to a dry and wet dual-purpose high-speed shearing type pulverizer. BACKGROUND

[0002] The conventional biological organic material fine pulverizer has a large difference in particle size after the material is pulverized. For example, the high-speed wall breaking machine has a large particle diameter and uneven particle fineness, generally between 0.06-0.25mm, and a large proportion of large particles. In addition, the existing fine pulverizer has the problems of large energy consumption, low pulverizing efficiency, and low particle uniformity.

[0003] The conventional high-speed blade stirring type pulverizing principle only has the impact breaking mode between the blade and the particles when the particle size is small to a certain extent. When the material is pulverized to a small size, the material is rotated with the blade driven by the high-speed rotation of the blade, which further reduces the impact breaking effect between the powder and the blade. For the fiber particles with good toughness, the impact breaking effect is small, and there is almost no further pulverizing effect. SUMMARY

[0031] The application discloses a device for crushing materials, which comprises a crushing cavity 1, a feeding hopper 2, a blade shaft group 10, a discharge port 3, a motor mounting rack 4 and straight-connected driving motors 5.

[0032] Further, the motor mounting rack 4 is fixedly installed on the outer side of the crushing cavity 1, the straight-connected driving motors 5 are fixedly installed on the outer side of the motor mounting rack 4, the number of the straight-connected driving motors 5 is six, one end of the straight-connected driving motor 5 is in transmission connection with a shaft coupling 6, and the number of the shaft couplings 6 is six. Through the arrangement of the motor mounting rack 4, the stability of the crushing cavity 1 and the straight-connected driving motors 5 can be ensured. Through the driving of the straight-connected driving motors 5, the shaft couplings 6 and a linkage shaft 7 can be driven to rotate, so that a fine crushing blade group 16 and a coarse crushing blade group 17 are driven to rotate, and materials are crushed.

[0033] Further, the linkage shaft 7 is in transmission connection with one end of the shaft coupling 6, the number of the linkage shafts 7 is six, the outer side of the linkage shaft 7 is installed with a bearing seat 8, the size of the bearing seat 8 is larger than that of the linkage shaft 7, a blade shaft seal 9 is arranged between the linkage shaft 7 and the bearing seat 8, and the number of the blade shaft seals 9 is six. Through the arrangement of the bearing seat 8, the linkage shaft 7 can be fixed so as not to shake easily.

[0034] Further, the blade shaft group 10 comprises a blade group fixed end plate 11 and a blade group fixed shaft 12, the blade group fixed end plate 11 is fixedly installed on the outer side of the blade group fixed shaft 12, and the number of the blade group fixed end plates 11 is two.

[0035] Specifically, the blade shaft group 10 adopts a six-shaft layout, each blade shaft is directly connected with a high-speed brushless DC motor through a shaft coupling, the rotating speed of the motor is 3000 rpm or 6000 rpm, the power of a single motor is 750 W-1500 W, the motors are installed at two ends of the crusher, and three motors are installed at each end. The structural design greatly simplifies the mechanical structure of the whole device, and improves the stability and reliability of the whole device.

[0036] Further, the blade mounting shaft 13 and the blade mounting adjustment ring 14 are in transmission connection with the linkage shaft 7, the number of the blade mounting shaft 13 and the blade mounting adjustment ring 14 is 12 per shaft, the blade group locking nut 15 is threadedly connected outside the blade mounting shaft 13 and the blade mounting adjustment ring 14, and the number of the blade group locking nut 15 is 4 per shaft.

[0037] Specifically, the blade mounting shaft 13 and the blade mounting adjustment ring 14 adopt a six-shaft layout, so that each blade can form two stable shearing and crushing working zones, greatly increasing the number of shearing working zones and the number of working shearing blades in pairs, and accordingly greatly improving the working efficiency of shearing and crushing.

[0038] Further, the fine crushing blade group 16 is fixedly connected outside the blade mounting shaft 13, the number of the fine crushing blade group 16 is 6 per shaft, the fine crushing blade group 16 has 15 blade edge holes, the blade edge is a circular arc curve profile, the blade diameter is 80-120 mm, the blade thickness is 6-10 mm, the blade end face is provided with a straight taper, the taper angle is 3-8°, the number of the coarse crushing blade group 17 is 6 per shaft, the coarse crushing blade group 17 has 8 blade edge holes, the blade edge is a circular arc curve profile, the blade diameter is 80-120 mm, the blade thickness is 6-10 mm, the blade end face is provided with a straight taper, and the taper angle is 3-8°.

[0039] Specifically, the fine crushing blade group 16 and the coarse crushing blade group 17 are both closed disc blades, the coarse crushing blade and the fine crushing blade adopt a closed disc structure with a straight taper, the distance between two adjacent blades can be conveniently adjusted, and the distance between the blades can even be adjusted to close to 0. Since the closed disc structure is adopted, mechanical accidents such as blade breakage caused by collision of exposed blade teeth due to too close distance between two adjacent open disc blades are avoided.

[0040] Example one: For traditional deep processing of soybean products, a large amount of soybean dregs is usually generated. According to statistics, about 1.2 tons of wet soybean dregs are generated per ton of soybean processed. Since the wet soybean dregs still contain a large amount of protein (about 17%), they will soon spoil and produce a foul odor at room temperature, which brings serious problems to the surrounding environment.

[0041] The general treatment method for wet soybean dregs is to sell them to breeders at an extremely low price for feed, but due to the great changes in the breeding pattern, the processing method of soybean dregs for feed is extremely unstable, and even many soybean dregs are not wanted.

[0042] The fresh wet bean dregs are re-pulverized by a high-speed shearing pulverizer to produce a slurry, and the coarse fragments in the bean dregs are pulverized into extremely fine fiber particles (400-800 mesh in fineness). The slurry of the extremely fine fiber particles contains abundant soybean cellulose polysaccharides and macromolecular proteins, which are usually referred to as dietary fiber. In other words, the waste bean dregs are converted into soybean dietary fiber by the method of ultrafine pulverization, and the soybean dietary fiber is added into flour in a proper proportion to produce soybean high-fiber noodles and soybean high-fiber bread.

[0043] In the second embodiment, since the distance between the blades can be adjusted to be close to 0, the shearing effect of the blade edges is always in good play, which effectively ensures the continuous fine pulverization effect. In addition, when the conical surfaces of the adjacent blades are worn, the blade edges have a certain self-sharpening function, and the distance between the blades will increase, but by adjusting the locking nuts at both ends of the blade shaft, the distance between the blades of the cutter group can be simply restored. In this way, the good pulverization effect of the whole machine can be continuously maintained.

[0044] The machine adopts a six-axis layout, so that each blade can form two stable shearing and pulverizing working zones, greatly increasing the number of shearing working zones and the number of paired working shearing edges, and correspondingly greatly improving the shearing and pulverizing efficiency.

[0045] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the scope of the present application shall be included in the protection scope of the present application.
