technical field

The invention relates to the technical field of impurity removal devices, in particular to a straw impurity removal device.

Background technique

my country is a large agricultural country, and the annual waste of crop straw, such as rice straw, wheat straw, corn straw, etc., exceeds 700 million tons. If the straw can be degraded into hydrolyzed sugar by biological fermentation, and further converted into L- Lactic acid or other products, its industrial prospects will be very broad. L-lactic acid is widely used in food, medicine, feed, chemical industry and other fields. Before using straw, it is necessary to remove mixed sediment and other sundries to avoid problems such as these sundries affecting the raw material composition and causing damage to subsequent machinery and equipment. , the usual treatment method is to wash the waste after crushing and sieving.

The traditional straw removal device cleans the straw by crushing it. Most of the straw has a hollow structure inside. After crushing, the internal gap is easy to enter the sediment, and the cleaning is not clean enough. Moreover, the effect of the traditional straw removal device is relatively low. Difference.

As a further description of the above technical solution:

A reversing frame for reversing the straw is welded on the reversing roller in a circular equiangular manner.

As a further description of the above technical solution:

The rotating connecting shaft and the straw conveying frame are parallel to each other, and the length of the rotating connecting shaft is equal to the width of the straw conveying frame.

As a further description of the above technical solution:

There are four rotating bearings in total, and each rotating bearing is welded with two rubber protrusions, and the two rubber protrusions are symmetrical with respect to the rotating bearing.

In the present invention, firstly, the stalks can be turned over by the turning rollers, so that the stalks can be fully cleaned, the cleaning effect is improved, and the stalks are cleaned more thoroughly. Secondly, the stalks are cleaned of impurities The device can directly remove impurities from the straw without crushing the straw first, preventing the sand from entering the internal space after the straw is crushed and making it impossible to clean up, thus improving the cleaning effect of the straw. When the rotating bearing on the rotating connecting shaft rotates, the rubber protrusions on the rotating bearing can knock the straw conveying frame, thereby driving the straw conveying frame to vibrate, making it easier for the sediment to go down the road, and further improving the cleaning effect.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

Referring to Figures 1-3, a straw removal device includes a removal device body 1, a turning roller 2 is rotatably connected to the center of the top of the removal device body 1, and the top of the removal device body 1 is located at the center of the turning roller 2. The first booster pump 7 and the second booster pump 9 are screw-connected on both sides. The bottom of the impurity removal device body 1 is connected to the waste water collection bin 3. The bottom of the impurity removal device body 1 is located on one side of the waste water collection bin 3 through the motor base. 6. The rotating motor 5 is fixed on the screw, and the rotating motor 5 is connected to the turning roller 2 through the transmission belt 4. The first booster pump 7 and the second booster pump 9 on the top of the impurity removal device body 1 are respectively connected to the The washing rack 11 is connected with the washing nozzle 12, the bottom of the impurity removal device body 1 is rotatably connected to the straw conveying rack 13, and the inside of the impurity removing device body 1 is located at the bottom of the straw conveying rack 13 and is connected to the Rotating bearing 15, and rubber boss 16 is welded on the rotating bearing 15.
