Description

Technical Field

[0001] This utility model relates to the field of feed processing equipment technology, and more specifically, to a mixing and stirring device for feed processing. Background Technology

[0002] The production of extruded feed includes steps such as raw material preparation, mixing, extrusion, drying, seasoning, and screening. Raw material preparation refers to the proportioning of raw materials according to the needs of animal husbandry, such as mixing ingredients like corn, wheat bran, and fishmeal in a pre-set ratio. Then, the mixing step blends the proportioned raw materials to ensure even distribution of each component. In practical production, some small-scale mixing equipment has a simple structure and is mainly suitable for simple mixing of coarse-particle raw materials at room temperature (around 25℃). It cannot effectively mix powdered raw materials or mix powdered raw materials with coarse-particle raw materials, especially in cold, dry weather. In such cases, manual addition of hot water or moving the equipment to a warmer area (such as a heated room) is necessary for mixing, which is detrimental to improving mixing efficiency. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a mixing and stirring device for feed processing to solve the technical problem of low mixing efficiency in existing feed mixing and stirring devices when mixing powdery raw materials with each other or with coarse particles.

[0004] According to an embodiment of the present invention, a mixing and stirring device for feed processing includes a support frame and a mixing chamber mounted on the support frame. The mixing chamber contains a stirring mechanism and a humidifying and heat-preserving mechanism. The stirring mechanism includes a first stirring component and a second stirring component that are parallel to each other and rotate in opposite directions. The humidifying and heat-preserving mechanism is located above the stirring mechanism and includes a liquid tank, a spray pipe, and nozzles. The liquid tank is located above the outside of the mixing chamber, and the nozzles are located above the inside of the mixing chamber. The outlet of the liquid tank is connected to the inlet of the spray pipe. A valve is also provided at one end of the spray pipe near the outlet of the liquid tank. The outlet of the spray pipe is connected to a plurality of nozzles, which are evenly distributed above the first stirring component and the second stirring component.

[0005] According to some embodiments of this utility model, the spray pipe is in one of the following shapes: U-shaped, S-shaped, umbrella-shaped, etc.

[0006] According to some embodiments of the present invention, both the first stirring assembly and the second stirring assembly include stirring blades, and the stirring blades on the two stirring assemblies are arranged alternately.

[0007] According to some embodiments of the present invention, the stirring blades can be disassembled.

[0008] According to some embodiments of this utility model, the stirring blade is one of the following: paddle type, spiral type, turbine type, etc.

[0009] According to some embodiments of the present invention, the feed processing mixing and stirring equipment further includes a plurality of lifting devices, which are located at the end of the support away from the mixing box.

[0010] The lifting device includes a lifting drive mechanism, a lifting mechanism, and a sliding mechanism. One end of the lifting mechanism is drivenly connected to the lifting drive mechanism. The sliding mechanism is located at the bottom end of the lifting mechanism and moves freely in the vertical direction under the drive of the lifting mechanism.

[0011] According to some embodiments of the present invention, the lifting mechanism includes a lifting shaft and a telescopic component. One end of the lifting shaft is driven to the lifting drive mechanism, and the other end is threaded to the telescopic component. The sliding mechanism is located at the bottom end of the telescopic component.

[0012] According to some embodiments of this utility model, the sliding mechanism is a universal wheel.

[0013] According to some embodiments of the present invention, the upper part of the mixing tank is provided with a feed inlet, and the bottom of the mixing tank is provided with a discharge outlet.

[0014] A mixing and stirring device for feed processing according to an embodiment of the present utility model has at least the following beneficial effects:

[0015] According to the present invention, when using a feed mixing and stirring device to mix different types of powdered raw materials or powdered raw materials with coarse particles, the inlet of the spray pipe is connected to the outlet of the liquid tank, and the outlet of the spray pipe is connected to several nozzles. A valve is also installed at the end of the spray pipe near the liquid tank. When the valve is closed, the solution can be circulated and heated in the liquid tank with heating and heat preservation function. When the valve is open, the solution in the heated and heat-preserved liquid tank is evenly sprayed through the nozzles onto the top of the first stirring component and the second stirring component, humidifying the powdered raw materials or powdered raw materials with coarse particles in the mixing tank. Obviously, the feed mixing and stirring device of this embodiment can obtain a solution with a higher temperature, which is more conducive to the effective mixing and stirring of powdered raw materials or powdered raw materials with coarse particles.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0028] As can be seen from the background technology, current feed processing mixing equipment does not have an effective mixing mechanism to adjust the mixing direction when mixing different types of feed ingredients. As a result, the mixing direction is always in the same direction, and the feed ingredients have low mixing efficiency and uneven mixing, which is not conducive to improving production efficiency.

[0029] Therefore, this utility model proposes a mixing and stirring device for feed processing, which is suitable for mixing and stirring between powdery raw materials or between powdery raw materials and coarse granular raw materials.

[0030] Please see Figure 1 The feed processing mixing and stirring equipment provided in this embodiment includes a support 1 and a mixing box 2 mounted on the support 1. The mixing box 2 is provided with a stirring mechanism 21 and a humidifying and heat-preserving mechanism. The stirring mechanism 21 includes a first stirring component 211 and a second stirring component 212 that are parallel to each other and rotate in opposite directions. The humidifying and heat-preserving mechanism is located above the stirring mechanism 21 and includes a liquid tank 4, a spray pipe 5, and nozzles 6. The liquid tank 4 is located above the outside of the mixing box 2, and the nozzles 6 are located above the inside of the mixing box 2. The outlet of the liquid tank 4 is connected to the inlet of the spray pipe 5. A valve 7 is also provided at one end of the spray pipe 5 near the outlet of the liquid tank 4. The outlet of the spray pipe 5 is connected to a plurality of nozzles 6, and the nozzles 6 are evenly distributed above the first stirring component 211 and the second stirring component 212.

[0031] Understandably, since the first stirring component 211 and the second stirring component 212 are parallel to each other and rotate in opposite directions, the movement of feed in the stirring tank 2 is prevented from being solely in one direction. This avoids the problems of low stirring efficiency and uneven stirring caused by a single stirring direction, greatly improving production efficiency. Furthermore, the inlet of the spray pipe 5 is connected to the outlet of the liquid tank 4, and the outlet of the spray pipe 5 is connected to several nozzles 6. A valve 7 is also installed at the end of the spray pipe 5 near the outlet of the liquid tank 4. When the valve 7 is closed, the solution in the liquid tank 4 can be circulated, heated, and kept warm within the liquid tank 4. When the valve 7 is open, the solution heated by the liquid tank 4 is evenly sprayed above the first stirring component 211 and the second stirring component 212 through the nozzles 6. Understandably, the liquid tank 4 has a heating function; a heating jacket or heating plate 8 can be installed outside the liquid tank for heating, and a temperature controller 9 can be installed for precise temperature measurement. Obviously, the feed mixing and stirring equipment of this embodiment can produce a liquid with a higher temperature, which is evenly sprayed above the first and second stirring components. This facilitates effective mixing and stirring between powdered raw materials or between powdered raw materials and coarse-particle raw materials, further improving the stirring efficiency. Those skilled in the art will understand that valve 7 can also control the flow rate, thereby controlling the amount of solution sprayed into the powdered raw materials within a reasonable range.

[0032] It should be noted that the stirring mechanism 21 also includes a stirring drive component 213. The first stirring assembly 211 is driven by the stirring drive component 213. The first stirring assembly 211 includes a first rotating shaft with a first gear 2111 mounted on it. The second stirring assembly 212 includes a second rotating shaft with a second gear 2121 mounted on it. The first gear 2111 and the second gear 2121 are meshed together. It can be understood that the first stirring assembly 211 and the second stirring assembly 212 are connected by the meshing of the first gear 2111 and the second gear 2121, achieving opposite rotation directions. Furthermore, the stirring drive component 213 is only driven by the first stirring assembly 211, enabling the first stirring assembly 211 and the second stirring assembly 212 to move simultaneously in different directions. This configuration saves space by eliminating the need for a separate drive component, reducing equipment weight and cost. Moreover, the gear transmission between the first stirring assembly 211 and the second stirring assembly 212 results in a compact structure, stable operation, and low vibration, making it particularly suitable for applications with limited space. In this embodiment, the first gear and the second gear can be spur gears, helical gears, or gears of other shapes. Those skilled in the art can make adaptive selections as needed.

[0033] In a further embodiment of this utility model, the spray pipe 5 is in the shape of a U, S, umbrella, or serpentine. This embodiment does not limit the specific shape of the spray pipe, as long as it achieves uniform spraying. Uniform spraying can further improve mixing efficiency.

[0034] In a further embodiment of this invention, both the first stirring assembly 211 and the second stirring assembly 212 include stirring blades, and the stirring blades on the two stirring assemblies are arranged in an alternating manner. The stirring blades generate centrifugal force and shear force through rotational motion, which can break up coarse particles in the mixing chamber 2 and allow the broken feed materials to continue to mix. The alternating arrangement of the stirring blades on the two stirring assemblies can further improve the stirring efficiency and mixing uniformity.

[0035] In a further embodiment of this invention, the stirring blades are detachable. Multiple mounting positions are provided on the rotating shaft of the stirring assembly, and multiple stirring blades are installed at different mounting positions on the shaft with adjacent stirring blades having the same spacing. By making the stirring blades detachable, those skilled in the art can set different numbers of stirring blades according to different types of raw materials, thereby achieving different blade spacings and meeting different production needs.

[0036] It is understandable that different shapes of stirring blades have different effects on the mixing effect of feed. The shape design of the stirring blades controls the movement of feed ingredients within the mixing chamber 2. In this embodiment, the stirring blades can be one of the following: paddle type, spiral type, turbine type, etc. This embodiment does not limit the specific shape and number of stirring blades. Those skilled in the art can make adaptive selections according to the different types of feed ingredients, as long as they can quickly crush coarse particles within the chamber and maintain a uniform distribution.

[0037] Please see Figure 3 In a further embodiment of this utility model, the feed processing mixing and stirring equipment further includes multiple lifting devices 3, which are located at the end of the support 1 away from the mixing box 2. Specifically, the lifting device 3 includes a lifting drive mechanism 31, a lifting mechanism 32, and a sliding mechanism 33. One end of the lifting mechanism 32 is drivenly connected to the lifting drive mechanism 31, and the sliding mechanism 33 is located at the bottom end of the lifting mechanism 32. The sliding mechanism 33 moves freely in the vertical direction under the drive of the lifting mechanism 32.

[0038] Those skilled in the art will understand that when the sliding mechanism 33 moves vertically downwards to contact the ground and supports the mixing tank 2, the bracket 1 is lifted off the ground, allowing the feed processing mixing equipment to slide freely. When the lifting drive mechanism 31 reverses, the lifting mechanism 32 moves upwards in the vertical direction, thereby driving the sliding mechanism 33 upwards and storing it. The feed processing mixing equipment can then be fixed by the bracket 1. The design of the lifting device 3 facilitates the handling and transportation of the equipment, improves operational flexibility, and brings great convenience to industrial production and operators. In this embodiment, the lifting drive mechanism can be lifted using hydraulic, pneumatic, or foot-operated methods. This embodiment does not limit the specific implementation of the lifting drive mechanism, as long as it can drive the lifting mechanism to move up and down.

[0039] In a further embodiment of this utility model, the lifting mechanism 32 includes a lifting shaft 321 and a telescopic member 322. One end of the lifting shaft 321 is drivenly connected to the lifting drive mechanism 31, and the other end is threadedly connected to the telescopic member 322. The sliding mechanism 33 is disposed at the bottom end of the telescopic member 322.

[0040] Obviously, when the lifting drive mechanism 31 drives the lifting shaft 321 to rotate, the telescopic member 322, which is threadedly connected to the lifting shaft 321, moves freely in the vertical direction, thereby driving the sliding mechanism 33 located at the bottom of the telescopic member 322 to move in the vertical direction. The lifting is achieved through the threaded connection between the lifting shaft and the telescopic member, which has high structural reliability and is easy to operate.

[0041] In a further embodiment of this utility model, the sliding mechanism 33 is a universal wheel 331. Because the universal wheel has the advantage of sliding freely in all directions, when the telescopic member 322 drives the universal wheel 331 to move downwards and contact the ground, the feed processing mixing and stirring equipment can move freely in all directions, further improving operational flexibility.

[0042] Please see Figures 1 to 3 In a further embodiment of this utility model, the upper part of the mixing tank 2 is provided with a plurality of feed inlets 22, and the bottom of the mixing tank 2 is provided with a plurality of discharge outlets 23. A material holding device is provided below the discharge outlets 23, and the material holding device is a heat-insulating container. This embodiment does not limit the number and specific location of the discharge outlets and feed inlets, and those skilled in the art can make appropriate selections according to the shape and movement mode of the stirring blades and the size of the mixing tank.

[0043] Obviously, the feed processing mixing and stirring equipment provided by this utility model embodiment can change the stirring direction of the raw materials in the mixing tank, avoiding the problems of low stirring efficiency and uneven stirring caused by a single stirring direction. It can realize the mixing and stirring of different kinds of feed raw materials. Especially in low temperature and dry weather, it can humidify and keep the solution and raw materials in the mixing tank warm, further improving the stirring efficiency and mixing effect. It can also realize the flexible movement of the feed processing mixing and stirring equipment, thereby improving the convenience of operation.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
