Description

Technical Field

[0001] This utility model relates to the field of material mixing technology, and in particular to a mixing and stirring device. Background Technology

[0002] In cat litter production, mixing is a crucial step, aiming to thoroughly and evenly combine base materials such as bentonite and tofu residue with additives like deodorizers and binders. Currently, most commercially available mixing devices typically have only one main feed inlet, or, while having a secondary feed inlet, a simple structure. In practice, workers need to feed large quantities of additives from a single point. These lightweight, dust-generating powdery additives quickly accumulate in localized areas of the mixing tank, making it difficult to quickly integrate with the base materials and easily forming clumps, resulting in uneven mixing. To achieve the required uniformity, mixing time must be significantly extended, which not only reduces production efficiency and increases energy consumption but also leads to unstable mixing quality, directly affecting the clumping and deodorizing effects of the cat litter product.

[0003] Therefore, this application provides a mixing and stirring device to solve the above-mentioned technical problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a mixing and stirring device to solve the problems of uneven mixing, easy agglomeration, low stirring efficiency and dust emission caused by the centralized addition of additives in existing devices.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A mixing and stirring device includes a support frame, on which a mixing tank is mounted. A stirring mechanism is installed inside the mixing tank. A discharge port is provided at the bottom of the mixing tank. A top cover is fixed to the top of the mixing tank. A main feeding hopper is provided on the upper surface of the top cover. A feeding pipe is horizontally inserted through the top of the mixing tank. One end of the feeding pipe extends out of the outside of the top of the mixing tank and is fixed to a secondary feeding hopper. A sprinkling port is opened on the lower surface of the feeding pipe inside the mixing tank, and an auger is rotatably installed inside the feeding pipe.

[0006] Optionally, multiple feeding ports are provided and are evenly distributed along the axial direction of the feeding pipe.

[0007] Optionally, a feeding motor is fixed to one end of the feeding pipe outside the mixing tank, and the output end of the feeding motor is fixed to one end of the auger.

[0008] Optionally, a dustproof baffle is installed on the top of the mixing tank, and the dustproof baffle is located between the lower port of the main feeding hopper and the upper part of the feeding pipe.

[0009] Optionally, the dust baffle has an inverted V-shaped structure, and multiple connecting strips are fixed at both ends of the dust baffle, the connecting strips being connected to the inner wall of the mixing tank.

[0010] Optionally, the stirring mechanism inside the stirring tank includes a sealed housing, a stirring motor, and a stirring shaft.

[0011] Optionally, the sealed housing is fixed in the middle of the mixing tank and located below the feeding pipe, and the mixing motor is fixed inside the sealed housing. The shaft of the mixing motor is fixed to the top end of the mixing shaft, and the mixing shaft is located at the bottom of the mixing tank.

[0012] Compared with the prior art, this utility model has at least the following beneficial effects: In the above scheme, by setting up a feeding pipe that is horizontally inserted at the top of the mixing tank, a sprinkling port that is axially distributed on its lower surface, and an auger driven by a conveying motor inside, the additives fed from the auxiliary feeding hopper can be forcibly conveyed and evenly and dispersedly sprinkled from the narrow sprinkling area, thereby maximizing the contact area between the additives and the base material, effectively preventing local agglomeration, and significantly improving the mixing efficiency and uniformity. In the above solution, the inverted V-shaped dust baffle and its connecting strip located between the main feeding hopper and the feeding pipe can physically block the escape path of the stirring dust and the feeding dust, forcing the dust to fall back into the tank after collision, thus greatly suppressing the escape of dust from the main feeding port, improving the working environment and reducing material loss.

[0013] In summary, this device not only achieves automated and uniform feeding of additives during cat litter production, but also effectively solves the dust pollution problem during the mixing process, resulting in good overall performance. Attached Figure Description

[0019] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0020] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0021] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0022] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings.

[0023] like Figure 1-4 As shown, an embodiment of this utility model provides a mixing and stirring device, mainly composed of a support part, a stirring body, a feeding system, and a dustproof structure. The support part includes a rigid bracket 1 welded from structural steel, which provides a stable foundation for the entire device. A stirring tank 2 is bolted to the top of the bracket 1. A discharge port 201 is provided at the center of the bottom of the stirring tank 2. A pneumatic butterfly valve or a manual slide valve is installed at the discharge port 201 to control the discharge of the finished material.

[0024] A hinged top cover 3 is fixedly installed on the top of the mixing tank 2 via flanges and gaskets. A funnel-shaped main feed hopper 301 is welded to the center of the upper surface of the top cover 3 for the feeding of large quantities of base material. On one side of the top of the mixing tank 2, a feed pipe 4 is horizontally inserted. One end of the feed pipe 4 extends outward from the top of the mixing tank 2, and a conical secondary feed hopper 401 is fixedly connected to this exposed end via a flange for receiving powdered materials to be added later. The other end of the feed pipe 4 is located inside the mixing tank 2, with multiple evenly spaced spouts 402 along the axial direction. To further optimize the uniformity of feeding, an auger 5, matching the inner diameter of the feed pipe 4, is rotatably installed inside the feed pipe 4 via bearing seats at both ends. A conveying motor 501 is fixedly installed at one end of the feeding pipe 4 outside the mixing tank 2 via a motor base. The output shaft of the conveying motor 501 is rigidly connected to the drive end of the auger 5 via a coupling, thereby providing rotational power to the auger 5 and realizing the uniform pushing and dispersion of materials from the auxiliary feeding hopper 401 to the sprinkling port 402.

[0025] To address the dust generated during feeding and mixing, an inverted V-shaped dust baffle 9 is installed at the top of the mixing tank 2, between the lower end of the main feeding hopper 301 and the upper part of the feeding pipe 4. This dust baffle 9 is preferably made of stamped stainless steel, with multiple connecting strips 901 symmetrically welded to both sides. The other ends of these connecting strips 901 are securely connected to the inner wall of the mixing tank 2 by screws, thus stably suspending the dust baffle 9 above the mixing area and effectively preventing dust from escaping upwards.

[0026] In addition, in this invention, the stirring power is provided by a stirring mechanism. Specifically, a sealed housing 6 is fixed to the geometric center of the mixing tank 2 by several support rods and is located below the feeding pipe 4. A stirring motor 7 is fixedly installed inside the sealed housing 6. The output shaft of the stirring motor 7 extends downwards and is fixed to the top of a vertically arranged stirring shaft 8 via a key connection. Various functional stirring blades are arranged on the stirring shaft 8 from top to bottom, such as fragmentation blades near the bottom and main stirring blades located in the upper middle part. These blades penetrate deep into the bottom of the mixing tank 2 to efficiently shear, convection, and diffusion mix the material.

[0027] The working principle of this utility model is as follows: First, cat litter base material is fed into the main feeding hopper 301. The stirring motor 7 is started, driving the stirring shaft 8 to rotate for initial mixing. Subsequently, when auxiliary materials need to be added, the conveying motor 501 is started, driving the auger 5 to rotate, forcibly conveying the auxiliary materials added from the secondary feeding hopper 401 and evenly spraying them out from a series of sprinkling ports 402, dispersing them into the base material being mixed. Throughout the process, the dust baffle 9 effectively suppresses dust from escaping from the main feeding hopper 301. Finally, the uniformly mixed material is discharged from the bottom outlet 201.

[0028] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
