Description

Technical Field

[0001] The utility model belongs to the technical field of mixing equipment, and particularly relates to a homogeneous mixing device for a feed processing production line. Background Technique

[0002] Feed is the general term for the food of farmed animals. More narrowly, generally, feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than a dozen varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, grease, meat and bone meal, grains, and feed additives.

[0003] At present, more and more livestock are raised. With the progress of society, the artificial breeding industry has developed greatly, and the demand for feed is increasing. The feed production process includes links such as raw material cleaning, crushing or grinding, mixing, granulation, drying, and packaging. The homogeneous mixing device is an essential processing machine in the feed processing production line. Structurally, the traditional homogeneous mixing device mainly includes a mixing tank body, a mixing component is arranged in the mixing tank body to perform a mixing operation on the materials in the tank body, and a driving component for driving the mixing component to rotate is arranged on the tank body.

[0004] Although the above-mentioned traditional homogeneous mixing device can perform a mixing operation on feed raw materials, there are certain limitations in actual use. Since the position of the mixing component of most homogeneous mixing devices is always in a constant state, the mixing range of the mixing component has certain limitations, resulting in poor mixing effects. In addition, after a sufficient mixing operation, it is necessary to open the discharge port at the bottom of the tank body, but the discharge port of the traditional homogeneous mixing device is small, and it is difficult to achieve rapid discharging, which leads to a long waiting time for the next mixing operation and affects the mixing efficiency of the feed. Therefore, it is urgent to design a homogeneous mixing device for a feed processing production line to solve the above problems. Summary of the Utility Model

[0005] The utility model provides a homogeneous mixing device for a feed processing production line with reasonable structural design and good mixing effect to solve the technical problems existing in the known technology. The utility model can perform a sufficient mixing operation on the materials in the mixing tank body and uniformly discharge the mixed materials after the mixing is completed, increasing the convenience and working efficiency of the mixing device.

[0006] The technical solution adopted by the present utility model to solve the technical problems existing in the known technology is as follows: A homogenizing and stirring device for a feed processing production line includes a stirring tank body with multiple groups of legs fixedly connected to the bottom. A discharge outlet is provided on the bottom surface of the stirring tank body, and a flap valve is inserted into the discharge outlet. A discharge assembly is connected and communicated at the discharge outlet for discharging operations. The discharge assembly includes a discharge shell structure that is butted against the discharge outlet and has a discharge port installed at the end. A discharge auger is arranged in the inner cavity of the discharge shell structure.

[0007] The advantages and positive effects of the present utility model are as follows: The present utility model provides a homogenizing and stirring device for a feed processing production line. By setting two sets of self-rotating stirring components and cooperating with the stirring drive component and the stirring shaft, the two sets of self-rotating stirring components can be driven to rotate while making a circular motion, so as to stir the feed raw materials entering the interior of the stirring tank body and have a certain stirring range, thereby improving the stirring effect on the raw materials. By setting the material pushing component, the materials can be stirred during the stirring operation and pushed towards the discharge outlet after the stirring operation is completed, facilitating the subsequent discharging operation. By setting the discharge assembly, the materials pushed into the discharge outlet can be discharged out of the stirring tank body evenly and quickly, avoiding the slow discharging process from affecting the working efficiency of the present utility model. By setting the wall scraping component, the materials can be stirred during the stirring operation and the inner wall of the stirring tank body can be scraped after the stirring operation is completed to achieve the cleaning operation, avoiding the sticky materials from adhering to the inner wall of the stirring tank body and affecting the stirring effect and subsequent mixing operation.

When it is necessary to discharge the materials stirred well inside the stirring tank body 6 at a constant speed, pull out the plug valve in the discharging outlet 14, start the discharging reduction motor 2-3 in the discharging component 2, drive the discharging auger 2-5 to rotate, and then discharge the materials that have completed the mixing operation out of the stirring tank body 6 at a constant speed and quickly, improving the use convenience and working efficiency of the stirring device.
