Description

Technical Field

[0001] This utility model belongs to the technical field of feed distribution and storage devices for livestock, specifically relating to a centralized distribution and storage device for liquid feed in pig farms. Background Technology

[0002] With the development of modern large-scale pig farming, liquid feeding systems are gradually replacing traditional dry feed feeding methods due to their advantages such as improved feed conversion rate, reduced dust pollution, and ease of automated management. However, existing centralized liquid feed distribution and storage devices still face many technical bottlenecks in practical applications. First, liquid feed is typically a mixture of water, crushed grains, protein powder, and additives. The significant difference in solid-liquid density means that prolonged standing can lead to sedimentation, stratification, and even clumping, resulting in uneven feed concentration and affecting the consistency of nutrient intake in the pig herd. Traditional solutions often rely on high-speed mixers installed inside the tank for continuous stirring, but this method is not only energy-intensive but can also damage heat-sensitive nutrients in the feed due to excessive shear force.

[0003] Secondly, existing distribution systems mostly use volumetric or simple flow meters for measurement, which cannot provide real-time feedback on the actual delivery volume and lack anomaly handling mechanisms. Once the pipeline experiences a slight blockage or pumping fluctuation, it can easily cause deviations in the feeding amount, and in severe cases, lead to feed shortages or overfeeding at the distribution end, affecting precise feeding management.

[0004] Furthermore, liquid feed residues can easily breed bacteria at the bottom of the tank, in bends, and at valves. Existing cleaning structures are mostly single top sprays, which do not provide complete cleaning coverage, leaving unsanitary areas and increasing the risk of disease transmission.

[0005] Currently, most liquid feed storage devices on the market adopt an integrated mixing + open-loop conveying structure, which has a single function and lacks intelligent feedback and adaptive adjustment capabilities, making it difficult to meet the needs of modern pig farms for efficient, precise, low-consumption, and safe feeding.

[0006] Based on this, a novel, functionally integrated, and reliable centralized distribution and storage device for liquid feed is proposed. Utility Model Content

The screening mechanism 4 is installed inside the storage cylinder 1 near the feeding end to perform initial screening of the liquid feed entering the storage cylinder 1. The cleaning system consists of a top cleaning mechanism 5 installed at the top of the storage cylinder 1 and a bottom cleaning mechanism 6 installed at the bottom of the storage cylinder 1 to complete the cleaning operation inside the storage cylinder 1.

[0022] In this embodiment, the storage cylinder 1 includes a cylindrical body 11, a top plate 12, a bottom plate 13, and a support 14; The cylindrical body 11 is a vertical cylindrical structure with a conical bottom and a central material collection area. A top plate 12 is fixed at the top of the cylindrical body 11, and the feeding mechanism 2 is installed on the top plate 12. A bottom plate 13 is installed on the outside of the cylindrical body 11 near the bottom end, and a bracket 14 is fixed on the outside of the bottom plate 13.

[0023] In this embodiment, a spiral guide plate 15 is also included; The spiral guide plate 15 is installed inside the storage cylinder 1. The spiral guide plate 15 can form an annular buffer settling zone inside the cylindrical body 11, which slows down the deposition rate of solid particles in the liquid feed to the bottom, realizes dynamic suspension, and prolongs the uniform suspension time of the liquid feed.

[0024] The feeding mechanism 2 consists of a feeding pipe 21 and a feeding pump 22. The feeding pipe 21 is connected to the center of the top of the cylindrical body 11. The feeding pump 22 is installed on the feeding pipe 21 and completes the feeding operation of external liquid feed into the cylindrical body 11 through the feeding pipe 21.

[0025] In this embodiment, the discharge mechanism 3 includes a liquid material delivery pipe 31, a waste material discharge pipe 32, and a return pipe 33; The waste discharge pipe 32 is installed at the bottom of the cylindrical body 11, and the liquid material delivery pipe 31 is installed on the side of the cylindrical body 11 near the bottom. The liquid material delivery pipe 31 is also connected to a return pipe 33, which is connected to the feeding mechanism 2.

[0026] A flow meter is also installed on the liquid feed delivery pipe 31. The flow rate of liquid feed is counted by the flow meter in the liquid feed delivery pipe 31. If excessive flow, abnormal flow rate or increased downstream pressure is detected, the valve installed on the liquid feed delivery pipe 31 is controlled to connect the return pipe 33, so that the excess or abnormal liquid feed is sent back to the cylindrical body 11 through the return pipe 33, thus realizing closed-loop control.

[0027] In this embodiment, the screening mechanism 4 includes a screening cylinder 41, a rotating shaft 42, a screening motor 43, and a slag discharge port 44; The rotating shaft 42 is rotatably connected to the storage cylinder 1, and the rotating shaft 42 is driven by the screening motor 43.

A slag discharge port 44 is also provided in the middle of the bottom end of the screening cylinder 41.

[0028] The liquid feed fed into the storage cylinder 1 is screened by the screening cylinder 41, which collects larger solid particles in the screening cylinder 41 to prevent the larger solid particles from clogging the discharge mechanism 3. At the same time, the rotating shaft 42 drives the screening cylinder 41 to stir the liquid feed in the cylindrical body 11, which improves the uniformity of the liquid feed.

[0029] In this embodiment, the top cleaning mechanism 5 consists of a top cleaning liquid pipe 51, an outer cleaning head 52, and an inner cleaning head 53.

Both the outer annular tube and the inner annular tube extend to the inner top surface of the cylindrical body 11. The top cleaning fluid tubes 51 are connected to the outer annular tube at equal intervals, and the inner cleaning heads 53 are installed on the inner annular tube at equal intervals on their outer sides.

[0030] The inner annular tube corresponds to the inner cavity area of ​​the screening cylinder 41, and the outer annular tube corresponds to the area inside the cylindrical body 11 and the area outside the screening cylinder 41, thereby enabling regionalized and precise cleaning operations.

[0031] The bottom cleaning mechanism 6 consists of a bottom cleaning fluid pipe 61 and a bottom cleaning head 62. The bottom cleaning fluid pipe 61 is installed on the outside of the cylindrical body 11 near the bottom end. At least four bottom cleaning heads 62 are installed on the bottom cleaning fluid pipe 61 at equal intervals. The inner end of the bottom cleaning head 62 extends into the cylindrical body 11 near the bottom end.

[0032] In practical use, both the top cleaning mechanism 5 and the bottom cleaning mechanism 6 are connected to an external cleaning water tank through cleaning water pipelines. The cleaning water is sent to the top cleaning mechanism 5 and the bottom cleaning mechanism 6 through the cleaning water pipelines. The outer cleaning head 52, the inner cleaning head 53 and the bottom cleaning head 62 respectively can spray high pressure to clean the inner cavity of the cylindrical body 11 and the screening cylinder 41. The cleaning waste liquid is discharged through the waste discharge pipe 32 to ensure that there is no feed residue and to prevent the growth of microorganisms, so as to facilitate the storage and distribution of liquid feed.
