Description

Technical Field

[0001] This utility model relates to the field of feed additive production technology, specifically a circulating mixing device for feed additive production. Background Technology

[0002] In the production process of pig feed additives, the raw materials, such as basic carriers (e.g., rice bran, wheat bran, soybean meal), functional active ingredients (e.g., *Dendrobium nobile* culture), and compound auxiliary agents (including trace minerals, vitamins, binders, etc.), need to be mixed in proportion. Currently, the industry generally uses vertical or horizontal mechanical mixing equipment to achieve raw material mixing through the single rotational shearing action of the mixing paddle.

[0003] However, due to the significant differences in the physical properties of various raw materials—the basic carrier is highly hygroscopic and prone to agglomeration, the *Agrosporium globosum* culture is lightweight and has poor flowability, and the compound adjuvant contains trace amounts of oil or hydrophilic substances—when relying solely on mechanical stirring in a static mixing container, localized high-humidity areas or electrostatic adsorption nuclei easily form between the raw material layers, causing fine powder particles to aggregate and grow around the active ingredients, resulting in clumping. Relying solely on the shearing action generated by the rotation of the stirring paddle is insufficient to effectively address the clumping problem, leading to unsatisfactory mixing results and severely affecting the quality of feed additive products.

[0004] Therefore, this utility model proposes a circulating mixing device for feed additive production to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a circulating mixing device for feed additive production to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A circulating mixing device for feed additive production includes a cylinder. The cylinder is divided into a mixing chamber and a dispersion chamber by a conical hopper. The mixing chamber is equipped with a stirring component, and the dispersion chamber is equipped with a dispersion component for dispersing feed additive raw materials. The dispersion component includes a crushing component and a shearing component arranged sequentially from top to bottom. The mixing device also includes a return component for returning the dispersed feed additive raw materials to the mixing chamber for re-mixing.

[0007] In one alternative embodiment: the stirring assembly includes a rotating rod and a driving component for rotating the rotating rod, wherein the driving component is provided with stirring blades evenly distributed on it.

[0008] In one alternative: the crushing component includes an installation sleeve, on which spiked rods are evenly distributed; a discharge port is provided on the conical bucket; a discharge plate is provided below the discharge port; the installation sleeve, the discharge plate, the rotating rod, and the discharge port are coaxially arranged; the lower end of the rotating rod passes through the discharge port and is fixedly connected to the discharge plate; and a discharge chute is provided circumferentially on the discharge plate.

[0009] In one alternative: the crushing component further includes several vibrating motors located on the bottom side of the mounting sleeve.

[0010] In one alternative embodiment: the shearing component includes multiple shearing meshes spaced apart from top to bottom, the shearing meshes being composed of multiple steel wires distributed in an interlaced manner, and the holes on the multiple shearing meshes being staggered in the vertical direction.

[0011] In one alternative embodiment: the mixing device further includes an opening and closing assembly for controlling the opening and closing of the material discharge port. The opening and closing assembly includes two opposing gates and two telescopic members. The movable ends of the two telescopic members are respectively fixedly connected to the two gates. The opposite sides of the two gates are provided with notches that are adapted to the half-side contour of the rotating rod.

[0012] In one alternative: the bottom of the dispersion chamber is provided with a discharge port, the discharge port is provided with a first valve and a discharge port, the discharge port is provided with a second valve, the feed end of the return material component is connected to the discharge port, and its discharge end is connected to the mixing chamber.

[0013] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows: The various raw materials that make up the feed additive are added to the mixing chamber according to the specified ratio. The mixing components stir and mix the raw materials. During this process, the raw materials also fall into the dispersion chamber, where the dispersion components disperse the falling raw materials to eliminate clumping and the tendency to clump. Then, the return components return the dispersed raw materials to the mixing chamber for mixing again. This cycle is repeated for a certain period of time to complete the mixing process. This effectively solves the problem of clumping when mixing the various raw materials that make up the feed additive, improves the mixing effect, and thus ensures the quality of the feed additive product.

Detailed Implementation

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Please see Figure 1 and Figure 2 A circulating mixing device for feed additive production includes a cylinder 1. The cylinder 1 is divided into a mixing chamber 101 and a dispersion chamber 102 by a conical hopper 2. The mixing chamber 101 is provided with a stirring component 4, and the dispersion chamber 102 is provided with a dispersion component 6 for dispersing feed additive raw materials. The dispersion component 6 includes a crushing component and a shearing component arranged sequentially from top to bottom. The mixing device also includes a return component 11 for returning the dispersed feed additive raw materials to the mixing chamber 101 for re-mixing.

[0025] It should be noted that the return material component 11 can be any one of a bucket elevator, a screw conveyor or a belt conveyor, and this application does not limit it. Its feed end is connected to the bottom of the dispersion chamber 102 and its discharge end is connected to the mixing chamber 101, so that the dispersed raw materials are returned to the mixing chamber 101 for re-mixing, forming a circulating raw material mixing method.

[0026] The various raw materials that make up the feed additive are added to the mixing chamber 101 (the mixing chamber 101 is equipped with a feeding port at the top) according to the specified ratio. The various raw materials are stirred and mixed by the stirring component 4. During this process, the raw materials also continuously fall into the dispersion chamber 102. The dispersion component 6 disperses the falling raw materials to eliminate agglomeration and agglomeration tendency. Then, the return component 11 returns the dispersed raw materials to the mixing chamber 101 for mixing again. This cycle is repeated for a certain period of time to complete the mixing. This effectively solves the problem of agglomeration when mixing the various raw materials that make up the feed additive, improves the mixing effect, and thus ensures the quality of the feed additive product.

[0027] Furthermore, the bottom of the dispersion chamber 102 is provided with a discharge port 7, the discharge port 7 is provided with a first valve 8 and a discharge port 9, the discharge port 9 is provided with a second valve 10, the feed end of the return material component 11 is connected to the discharge port 7, and its discharge end is connected to the mixing chamber 101. During the cyclic mixing, the first valve 8 is kept open and the second valve 10 is kept closed. After the mixing is completed, the first valve 8 is closed and the second valve 10 is opened. The mixed raw material is discharged through the discharge port 9. The first valve 8 and the second valve 10 can be opened / closed manually or electrically. This application does not limit this.

[0028] Please see Figures 2-6 In one embodiment of the present invention, the stirring assembly 4 includes a rotating rod 401 and a driving component 403 for rotating the rotating rod 401 (the driving component 403 is a servo motor, a geared motor, etc. in the prior art). The driving component 403 is provided with stirring blades 402 evenly distributed on it. The crushing component includes an installation sleeve 601, on which spiked rods 602 are evenly distributed. The conical bucket 2 is provided with a discharge port 3, and a discharge plate 605 is provided below the discharge port 3. The installation sleeve 601, the discharge plate 605, the rotating rod 401 and the discharge port 3 are coaxially arranged. The lower end of the rotating rod 401 passes through the discharge port 3 and is fixedly connected to the discharge plate 605. The discharge plate 605 is provided with a throwing groove 606 in the circumferential direction. The shearing component includes multiple shearing meshes 604 spaced apart from top to bottom. Each shearing mesh 604 is composed of multiple (thin) steel wires distributed in an interlaced manner, and the holes on the multiple shearing meshes 604 are interlaced in the vertical direction.

[0029] In this embodiment, the drive unit 403 drives the rotating rod 401 to rotate, which in turn drives multiple stirring blades 402 to operate and mix the raw materials. At the same time, it drives the discharge plate 605 to rotate, and the raw materials continuously fall into the discharge plate 605 through the discharge port 3 and are diverted into each discharge trough 606. Since the discharge plate 605 is rotating, under the action of centrifugal force, the raw materials in the discharge trough 606 are thrown towards the mounting sleeve 601. The spiked rod 602 breaks up the agglomerated raw materials, and then the raw materials fall down and pass through the shearing mesh 604 in sequence. The shearing mesh 604 shears and disperses the raw materials, eliminating the tendency to agglomerate. In addition, when the raw materials are thrown and impact the shearing mesh 604, the instantaneous impact causes the raw materials to scatter, which promotes mixing.

[0030] Furthermore, in this embodiment, the crushing component also includes several vibration motors 603 disposed on the bottom side of the mounting sleeve 601. The inner side of the mounting sleeve 601 is inclined. The vibration motors 603 cause the mounting sleeve 601 to vibrate, thereby causing the raw materials thrown onto the mounting sleeve 601 to fall quickly and avoid adhesion.

[0031] Furthermore, in this embodiment, the mixing device also includes an opening and closing assembly 5 for controlling the opening and closing of the material discharge port 3. The opening and closing assembly 5 includes two opposing gate plates 501 and two telescopic members 502 (preferably, the telescopic members 502 are electric telescopic rods). The movable ends of the two telescopic members 502 are respectively fixedly connected to the two gate plates 501. Each of the two gate plates 501 has a notch 503 on its opposite side that matches the half-side contour of the rotating rod 401 (to avoid the rotating rod 401 when the two gate plates 501 are closed). The two gate plates 501 are driven to open and close by the extension and retraction of the two telescopic members 502. The gate 501 is combined / separated (when the two gates 501 are combined, the upper side of the gate 501 is in contact with the lower edge of the discharge port 3, and the side wall of the notch 503 on the gate 501 is in contact with the rotating rod 401 (not stuck), and the rotating rod 401 can rotate), thus opening and closing the discharge port 3. In the raw material feeding stage (initial stage), the opening and closing component 5 is in the closed state of the discharge port 3 to prevent the raw material from falling directly into the dispersion chamber 102. After the feeding is completed, the raw material is stirred by the stirring component 4 for a certain period of time to achieve preliminary mixing, and then the opening and closing component 5 is opened again for cyclic mixing.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
