Description

Shaking screening filtering structure

Technical Field

The utility model belongs to the technical field of natto production facility, a shake screening filtration is related to.

Background

The natto freeze-dried powder is prepared by soaking and steaming soybean in a treatment solution, steaming at a temperature of more than 100 ℃, then crushing, inoculating, fermenting and drying.

However, most of the existing crushers filter out large-diameter particles by a multi-time crushing mode and perform secondary crushing on the large-diameter particles, which makes the process complicated and has the following disadvantages: 1. the filter screen is easy to block; 2. even if the materials are crushed for multiple times, particles still can be generated, so that part of the materials are wasted; 3. the crushing and screening need be carried out twice, which is not beneficial to improving the production efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a shake screening filtration to the above-mentioned problem that prior art exists, the utility model aims to solve the technical problem how to make granule and powder quickly separating through shaking the filter screen.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a shake screening filtration, its characterized in that includes the frame, connects the hopper and fixes the driving motor in the frame, the fixed screw rod that is provided with on driving motor's the output shaft, the middle part that connects the hopper has a conical filter screen, the bottom that connects the hopper has a feed cylinder that is located the outside of screw rod lower extreme, connect and link to each other through a plurality of spring posts between hopper and the frame, a mounting hole has on the feed cylinder, the lower extreme of screw rod is inserted and is established in the mounting hole, two guide blocks that have the symmetry on the mounting hole inner wall and set up, the outer wall of screw rod has the guide way with the guide block adaptation, the guide way includes two straight sections and two curved sections, straight section sets up with curved section is alternate.

In the rotatory in-process of screw rod, the guide block cooperates with the guide way, when the guide block is located straight section, the rotatory butt joint hopper of screw rod causes less resistance, it is close unmovable state to connect the hopper, when the guide block enters into curved segment by straight section, because the orbit changes, the rotatory butt joint hopper of screw rod causes great resistance, and form the impact to the butt joint hopper, make and connect the hopper to take place to rotate and longitudinal displacement, after the guide block reenters straight section, connect the hopper to reset under the effect of spring post, so relapse, connect the hopper in the state of intermittent type rotation and intermittent type nature reciprocating motion, the material shake in the butt joint hopper, make the powder material that can filter out as early as possible, the granule material that can not filter out deposits to connect the hopper bottom as early as possible.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 and 2, the feeding device comprises a frame 1, a feeding hopper 2 fixed on the frame 1, and a driving motor 3 fixed on the frame 1, wherein a crushing cutter wheel 21 is fixedly arranged on an output shaft of the driving motor 3, a discharging hole 22 matched with the crushing cutter wheel 21 is formed in the bottom of the feeding hopper 2, a screw 41 is further fixedly arranged on the output shaft of the driving motor 3, a return pipe 42 is sleeved outside the screw 41, an upper end opening of the return pipe 42 is positioned in the feeding hopper 2, a receiving hopper 43 fixed on the frame 1 is arranged below the feeding hopper 2, a conical filter screen 44 is arranged in the middle of the receiving hopper 43, a charging barrel 45 sleeved on the return pipe 42 is arranged at the bottom of the receiving hopper 43, a lower end opening of the return pipe 42 is positioned in the charging barrel 45, and a receiving barrel 5 is arranged below the filter screen 44.

The receiving hopper 43 is connected with the frame 1 through a plurality of spring columns 46, a mounting hole is formed in the charging barrel 45, the lower end of the screw rod 41 is inserted into the mounting hole, two guide blocks 47 which are symmetrically arranged are arranged on the inner wall of the mounting hole, a guide groove 48 matched with the guide blocks 47 is formed in the outer wall of the screw rod 41, the guide groove 48 comprises two straight sections 481 and two curved sections 482, and the straight sections 481 and the curved sections 482 are arranged alternately.

The lower end of the material return pipe 42 is fixedly connected with the inner wall of the charging barrel 45 through a plurality of web plates.

Bean blocks to be crushed enter from the feeding hopper 2, the materials are crushed under the matching of the crushing cutter wheel 21 and the inner wall of the blanking hole 22, the crushed materials enter the outer edge of the receiving hopper 43, the materials enter the bottom of the receiving hopper 43 along the outer edge of the receiving hopper 43 and pass through the filter screen 44 in the middle, powder capable of being filtered enters the receiving barrel 5 after passing through the filter screen 44, particle materials which cannot be filtered enter the bottom of the receiving hopper 43 and are fed into the feeding barrel 45, the screw rod 41 and the crushing cutter wheel 21 synchronously rotate, the particle materials in the feeding barrel 45 enter the top of the feeding barrel 45 through the screw rod 41, namely enter the feeding hopper 2 and are crushed by the crushing cutter wheel 21 again together with the raw materials to be crushed, and the circulation is adopted, the materials can be continuously crushed, and the particles are automatically filtered and then crushed again.

During the rotation of the screw 41, the guide block 47 is matched with the guide groove 48, when the guide block 47 is located in the straight section 481, the rotation of the screw 41 causes less resistance to the hopper 43, the receiving hopper 43 is in a state of approaching to an immovable state, when the guide block 47 enters the curved section 482 from the straight section 481, due to the change of the running track, the rotation of the screw 41 causes greater resistance to the receiving hopper 43 and impacts the receiving hopper 43, so that the receiving hopper 43 rotates and longitudinally displaces, after the guide block 47 enters the straight section 481 again, the receiving hopper 43 is reset under the action of the spring column 46, and the operation is repeated, when the receiving hopper 43 is in a state of intermittent rotation and intermittent longitudinal reciprocating motion, the materials in the receiving hopper 43 are shaken, so that powder materials which can be filtered out are filtered out as soon as possible, and granular materials which cannot be filtered out are precipitated in the barrel 45.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
