Description

Technical Field

[0001] The invention belongs to the technical field of feed production equipment, and in particular relates to a pet additive premix feed production equipment and a production process. Background Art

[0002] Premixed feed is a mixture of one or more additive raw materials or monomers and carriers or diluents, also known as additive premix or premix. The purpose is to facilitate the uniform dispersion of trace raw materials in a large amount of compound feed. In particular, in the production process of pet feed, some pet nutritional additives need to be added. Traditional feed mixing equipment almost all uses paddle rotation mixing, which has large resistance during the mixing process, directly leading to high energy consumption. In addition, the paddle size inside the paddle rotation mixing equipment is fixed, which will cause uneven mixing of the internal raw materials. Therefore, the existing paddle rotation mixing equipment cannot meet the growing demand for feed processing.

[0003] The existing Chinese patent document with publication number CN107772520A proposes a premixed feed ingredient mixing device and a feed production system, which adopts a main stirring body and an auxiliary stirring body to stir simultaneously, and can solve the above-mentioned problem in a way that can meet the mixing needs of different positions and different depths inside the ingredient stirring combination box. However, because a tubular stirring rod is used for stirring, there may be some hard-to-reach dead corners inside the box, resulting in insufficient mixing of ingredients in certain areas.

[0004] Therefore, the present invention proposes a pet additive premix feed production equipment and production process to solve the problem that when the stirring rod of the prior art is stirring, there may be some hard-to-reach dead corners inside the box, resulting in insufficient mixing of ingredients in certain areas. The stirring rod is improved and matched with an external sleeve to reversely transport the upper and lower layers of feed during the stirring process so that they are mixed and stirred evenly.

[0015] A pet additive premix feed production process comprises the following steps:

[0016] Step 1: Add a variety of premixed feeds into the triangular mixing cylinder, and use a dispersion net to filter and intercept large particles of feed;

[0017] Step 2: Start the driving motor and the air pump. The driving motor drives the central air inlet pipe to rotate. The dispersion net rotates with the central air inlet pipe and cooperates with the rolling frame to crush the large-particle feed. The air pump generates gas and transports it into the diverter box through the sealed pipe sleeve. The diverter box evenly disperses the gas into the auxiliary mixing and stirring pipe through the exhaust branch pipe. As the exhaust branch pipe rotates, the auxiliary mixing and stirring pipe and the C-shaped stirring blades also rotate at the same time to fully mix and stir the feed and additives in the triangular mixing cylinder.

[0018] Step 3: Add pet additives while stirring. The dispersion net rotates to disperse the additives evenly by utilizing the eccentricity. The spiral elevator is driven to rotate by the central air inlet pipe.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] By arranging a central air inlet pipe and a reflux pipe inside the triangular mixing cylinder, the premixed feed enters the inside of the triangular mixing cylinder from above, and the rotation of the central air inlet pipe drives the diverter box and the C-type stirring blades to rotate. The C-type stirring blades can increase the lateral shearing effect, thereby increasing the mixing force of the feed, and mixing the feed and additives. In conjunction with the air pump and the auxiliary mixing and stirring pipe, gas is introduced during the continuous mixing process, so that the feed particles are fully separated to avoid sticking. When the central air inlet pipe rotates, it will also drive the spiral lifter to rotate. Then, the mixed feed enters the reflux pipe through the feed inlet, is transported upward in the reverse direction, and is re-discharged through the discharge port for re-mixing, so that the feed at the bottom is fully mixed with the feed on the upper layer, thereby solving the problem that when the stirring rod in the prior art is stirring, there may be some hard-to-reach dead corners inside the box, resulting in insufficient mixing of ingredients in certain areas.

A feed inlet is provided above the upper cover 12, and the feed enters the triangular mixing cylinder 1 through the upper cover 12. The air inlet pipe mounting frame 42 plays the role of assisting the installation of the central air inlet pipe 4, so that the central air inlet pipe 4 is conveniently installed above the triangular mixing cylinder 1.

[0051] In this embodiment, the sliding frame 432 mainly serves to limit the dispersion net 45. The dispersion net 45 mainly rotates with the central air inlet pipe 4 to utilize the eccentricity to fully disperse the feed entering the triangular mixing cylinder 1 and filter the large-particle feed. The rolling frame 46 is installed, and the oblique shovel 462 intercepts and scoops up the large-particle feed filtered by the dispersion net 45.

The pet additive premix feed production equipment according to claim 2, characterized in that: A rolling frame (46) is fixedly installed below the intake pipe mounting frame (42) by means of bolts, a through slot matched with the triangular push rod (451) is provided above the rolling frame (46), a triangular pressing frame (461) is slidably installed on the side wall of the rolling frame (46), an oblique shovel (462) is fixedly installed on the bottom of the side surface of the rolling frame (46), and the lower surfaces of the rolling frame (46) and the triangular pressing frame (461) are in contact with the upper surface of the dispersion net (45).

9. The pet additive premix feed production equipment according to claim 8, characterized in that: A crushing roller (4611) is movably mounted on one side of the lower surface of the triangular pressing frame (461), and a crushing rib is arranged on the outer surface of the crushing roller (4611). A return spring (4612) is fixedly mounted on the other side of the lower surface of the triangular pressing frame (461), and the lower end of the return spring (4612) is fixedly connected to the bottom of the side wall of the rolling frame (46).

10. A pet additive premix feed production process, implemented by the pet additive premix feed production equipment according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Add a variety of premixed feeds into the triangular mixing cylinder (1), and use a dispersion net (45) to filter and intercept large particles of feed; Step 2, start the driving motor (2) and the air pump (3), the driving motor (2) drives the central air inlet pipe (4) to rotate, the dispersion net (45) rotates with the central air inlet pipe (4) and cooperates with the grinding frame (46) to grind and crush the large-particle feed, the air pump (3) generates gas and transports it into the diverter box (43) through the sealing pipe sleeve (31), the diverter box (43) disperses the gas evenly into the auxiliary mixing and stirring pipe (6) through the exhaust branch pipe (431), and as the exhaust branch pipe (431) rotates, the auxiliary mixing and stirring pipe (6) and the C-shaped stirring blade (44) also rotate at the same time, and the feed and additives inside the triangular mixing cylinder (1) are fully mixed and stirred, and the gas is discharged through the exhaust inclined pipe (64) during the rotation process to fully disperse the feed particles; Step 3, adding pet additives while stirring, the dispersion net (45) rotates to use the eccentricity to evenly disperse the additives, and the spiral lifter (53) is driven to rotate by the central air inlet pipe (4), so that during the stirring process, the feed enters the reflux pipe (5) from the feed inlet (51) and is transported upward by the spiral lifter (53) through the discharge port (52) and discharged again for stirring and mixing again, and the cycle is repeated so that the feed is fully mixed from top to bottom; Step 4, control the driving motor (2) to rotate in the reverse direction, open the discharge pipe (11) and the bottom discharge cover (55), and discharge the mixed feed through the lower end of the reflux pipe (5) and the triangular mixing cylinder (1).
