Description

Technical Field

[0001] This invention relates to the field of feed production technology, and in particular to a dust removal device for feed production. Background Technology

[0002] Feed is a general term for the food of animals raised by all people. In a narrower sense, feed generally refers to the food of animals raised in agriculture or animal husbandry.

[0003] Feed includes more than ten kinds of feed ingredients such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives. During the production process, the feed surface usually carries a lot of dust after being dried, and its temperature is also relatively high. It needs to be dusted and cooled before it can be packaged and transported.

[0004] However, a large amount of dust is often generated when pouring and crushing raw materials. Since the feed hopper is connected to the crushing chamber and is fixedly connected, the dust generated when the crushing roller processes the raw materials will spread from the feed hopper into the workshop. The dust raised when pouring will also spread into the workshop. A large amount of dust flies in the workshop, resulting in a poor working environment for the workers. Summary of the Invention

[0005] This invention provides a dust removal device for feed production, which aims to solve existing problems.

[0006] This invention is implemented as follows: a dust removal device for feed production, comprising: a production box; multiple support legs fixedly connected to the bottom of the production box; multiple casters with fixing devices installed at the bottom of the support legs; a feed inlet at the top of the production box; a discharge outlet at the bottom of the production box; a valve at the outlet of the discharge outlet; the bottom of the inner wall of the production box inclined towards the discharge outlet; multiple fixing mechanisms arranged in a circular array along the side wall of the feed inlet; a preliminary crushing device and an advanced crushing device arranged inside the production box; the preliminary crushing device located near the feed inlet; the advanced crushing device located near the discharge outlet; a transmission assembly arranged between the preliminary crushing device and the advanced crushing device; and a dust removal device arranged on the outer wall of the production box.

Multiple pressing springs 607 are respectively sleeved around the multiple connecting rods 606, with one end of each spring tightly abutting the pressing plate 605 and the other end tightly abutting the top wall of the sliding groove 604. The elastic force of the pressing springs 607 presses the pressing plate 605 tightly against the inner wall of the receiving groove 601. The production box 1 is equipped with a preliminary crushing device 7 and an advanced crushing device 8. The preliminary crushing device 7 is located near the feed inlet 4, and the advanced crushing device 8 is located near the discharge outlet 5.

The transmission belt 903 is sleeved on the first pulley 901 and the second pulley 902. When the rotary motor 705 drives the first rotating shaft 701 to rotate, the first pulley 901 rotates with the first rotating shaft 701. Through the transmission belt 903, the second pulley 902 and the advanced rotating shaft 801 are driven to rotate, which in turn drives multiple advanced crushing rollers 802 to rotate and further crush the feed raw materials. A dust removal device 10 is installed on the outer wall of the production box 1. The dust removal device 10 is used for dust removal. The dust removal device 10 includes a dust removal box, a fan, a main pipe and multiple suction branch pipes. The dust removal box 1001 is fixedly connected to the side wall of the production box 1. A sliding door is installed on the front of the dust removal box 1001 through multiple hinges. One end of the main pipe 1003 is fixedly connected to the dust removal box 1001, and the other end is fixedly connected to multiple suction branch pipes 1004. The ends of the multiple suction branch pipes 1004 away from the main pipe 1003 pass through the side wall of the production box 1 and circulate with the air inside the production box 1. The multiple suction branch pipes 1004 are evenly spaced longitudinally along the side wall of the production box 1. The end of the suction branch pipe 1004 inside the production box 1 is funnel-shaped. The fan 1002 is fixedly installed at the end of the main pipe 1003 near the dust removal box 1001. When the fan 1002 is started, the dust floating in the production box 1 is sucked into the dust removal box 1001.

[0023] The working principle of this invention is as follows: The opening of the feed raw material bag is clamped and fixed to the telescopic ends of multiple electric telescopic rods 602 by multiple spring clips 603. Pulling multiple connecting rods 606 causes the pressing plate 605 to move and retract into the sliding groove 604. The pressing plate 605 compresses the pressing spring 607, which is in an elastic contraction state. Then, the multiple electric telescopic rods 602 are controlled to retract, opening the bag opening until the telescopic ends of the electric telescopic rods 602 move into the receiving groove 601. After releasing the hand, press the spring 607 to rebound, push the pressing plate 605 back to its original position, and press the bag opening around the inner wall of the feed inlet 4 to isolate dust inside the bag and production box 1. This prevents dust from drifting out of the feed inlet 4 and polluting the working environment when dumping and crushing feed ingredients. When dumping, start the rotary motor 705 and the fan 1002. The rotary motor 705 drives the first rotating shaft 701 to rotate, and the first rotating shaft 701 drives the first crushing roller 702 and the first pulley 901 to rotate. The first crushing roller... Roller 702 drives the second crushing roller 704 to rotate together to initially crush the feed raw materials. The first pulley 901 drives the second pulley 902 through the transmission belt 903. The second pulley 902 drives the advanced rotating shaft 801 connected to it to rotate, which in turn drives multiple advanced crushing rollers 802 to rotate. The feed raw materials initially crushed by the initial crushing device 7 fall into the advanced crushing device 8 and are further crushed by multiple advanced crushing rollers 802. The feed raw materials that have undergone double crushing are output from the discharge port 5 at the bottom of the production box 1. The fan 1002 sucks up the dust in the production box 1 through multiple longitudinally distributed dust suction branches 1004. The dust suction branch 1004 near the feed inlet 4 sucks up the dust poured into the bag when the feed raw materials are poured out. The dust suction branch 1004 located between the initial crushing device 7 and the advanced crushing device 8 sucks up the dust generated after the initial crushing. The dust suction branch 1004 near the discharge port 5 sucks up the dust remaining after the secondary crushing. Through multiple dust suction, the dust removal effect is improved.

Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
