Description

Technical Field

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

[0002] In factory production, various raw materials need to be mixed. Generally, these raw materials include coarse and fine particles of different sizes and weights. These materials are mixed in specific proportions according to production requirements and needs before subsequent production. Mixing of multiple raw materials is typically done in a pneumatic mixing station. However, when dealing with a wide variety of raw materials with significant differences in particle size, relying solely on a pneumatic mixing station for mixing can be time-consuming. Under high production pressure, this can slow down the production schedule. Conventional mixers are insufficient to handle the fast-flowing, particulate materials. Incomplete mixing can lead to unstable product quality or decreased performance. Therefore, a new type of mixing machine is needed to effectively improve mixing efficiency and enhance production performance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a batching and mixing device that can effectively improve the mixing efficiency of coarse and fine materials, enhance the mixing effect of various raw materials, and effectively ensure production.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a batching and mixing device, including multiple individual material bins for storing various raw materials, a discharge valve is provided on the discharge pipe of each individual material bin, the discharge pipes of each individual material bin are connected to a conveying main pipe, a premixing device with a horizontally placed built-in spiral stirring paddle is connected to the conveying main pipe, and the tail end of the premixing device is connected to a pneumatic mixing station that can suck up the raw materials in the conveying main pipe through negative pressure through a conveying pipe.

[0005] A further improvement of the present invention is that the premixing device has a shuttle-shaped three-section structure, consisting of a feeding transition section, a middle section, and a discharging transition section from input to output.

[0006] A further improvement of this utility model is that the middle section of the premixing device is cylindrical, with two hanging fixed beams on the upper inner wall and a vertically upward fixed beam on the lower inner wall. The tail ends of the fixed beams are welded together to a horizontally suspended spiral stirring paddle inside the middle section.

[0007] A further improvement of this utility model is that: several inclined upward-facing bottom guide plates are provided on the inner wall below the middle section.

[0008] A further improvement of the present invention is that the feed transition section of the main feed pipe and the premixing device are connected and fixed by heavy-duty clamps, the feed transition section and the middle section are connected and fixed by heavy-duty clamps, the middle section and the discharge transition section are connected and fixed by heavy-duty clamps, and the discharge transition section and the feed pipe are connected and fixed by heavy-duty clamps.

[0009] A further improvement of this utility model is that a sealing ring is provided in the heavy-duty clamp.

[0010] A further improvement of this utility model is that the discharge valve is a star valve, and the opening and closing discharge time is controlled by a PLC.

[0011] The technological advancements achieved by this invention, due to the adoption of the above-mentioned technical solutions, are as follows: By installing a premixing device on the main conveying pipe where the feed pipes of multiple individual silos converge, the pneumatic mixing station draws raw materials from the main pipe under negative pressure. These materials of different particle sizes and types are continuously impacted and mixed as they pass through the spiral agitator in the premixing device. This premixing process effectively improves mixing efficiency before the main mixing process in the pneumatic mixing station. The premixing device is designed as a three-section, spindle-shaped structure, with each section connected and fixed using heavy-duty clamps. This facilitates smooth entry of raw materials into the premixing device and also makes subsequent disassembly and cleaning easier. The premixing device is configured with a fixed agitator, and the mixing method involves passive mixing of the raw materials impacting the agitator, which better handles the high flow rate of granular materials in this production process. An upward-sloping bottom guide plate is installed on the inner wall below the middle section. Particles that fall to the bottom under gravity after passing through the horizontal middle section are then guided upwards again by the inclined guide plate, further enhancing the premixing effect.

[0016] The present invention will be further described in detail below with reference to embodiments:

[0017] Example 1

[0018] like Figure 1 The diagram shows a structural schematic of a batching and mixing device of this invention. It includes multiple individual material bins 1 for storing various raw materials. Each individual material bin 1 has a discharge pipe 3 at its bottom for discharging the stored raw material. A discharge valve 2 is installed on the discharge pipe 3 to control the discharge. In this embodiment, each discharge valve 2 is a star valve, and the discharge time is controlled by a PLC, allowing for precise control of the discharge time. The discharge pipes 3 of each individual material bin 1 are connected to a main conveying pipe 4, meaning that the raw materials discharged from each individual material bin 1 will collect in the main conveying pipe 4.

[0019] A premixing device 5 is connected and installed at the tail end of the main conveying pipe 4, such as... Figure 2 As shown, the premixing device 5 has a shuttle-shaped three-section structure, consisting of a feeding transition section 51, a middle section 52, and a discharging transition section 53 in the direction from input to output. The tail end of the main conveying pipe 4 is connected to the feeding transition section 51 and fixed by heavy-duty clamps. A conveying pipe is fixed to the discharging transition section 53 by heavy-duty clamps. The conveying pipe is connected to the pneumatic mixing station 6. The middle section 52 of the premixing device 5 is cylindrical. Two hanging fixed beams 54 are welded to the front and rear ends of the upper inner wall of the middle section 52, and a vertically upward fixed beam 54 is welded to the middle of the lower inner wall. A horizontally suspended spiral agitator 56 is welded to the tail ends of all three fixed beams 54 and is suspended inside the middle section 52. The spiral agitator 56 is fixed and not driven by a motor. The mixing method involves the raw material particles impacting the spiral agitator 56. Under the negative pressure suction of the pneumatic mixing station 6, the particles are passively drawn through the blades of the spiral agitator 56, extending the mixing path and effectively premixing the high-velocity granular raw materials. Several inclined upward-facing bottom guide plates 55 are welded to the lower inner wall of the middle section 52 from input to output. This prevents the granular raw materials that fall onto the lower side wall due to gravity from moving only on the lower wall; instead, they move upward through the inclined guide plates, lengthening the mixing path and improving the premixing effect.

[0020] The shuttle-shaped three-section premixing device 5 is fixedly connected by heavy-duty clamps. Specifically, the main conveying pipe 4 is fixedly connected to the feeding transition section 51 of the premixing device 5 by heavy-duty clamps; the feeding transition section 51 is fixedly connected to the middle section 52 by heavy-duty clamps; the middle section 52 is fixedly connected to the discharge transition section 53 by heavy-duty clamps; and the discharge transition section 53 is fixedly connected to the conveying pipe by heavy-duty clamps. Each of these heavy-duty clamps is equipped with a sealing ring to better achieve sealing when mixing various particulate raw materials.

[0021] After the PLC controls each individual material bin 1 to discharge materials according to production requirements, the PLC controls the pneumatic mixing station 6 to start. Negative pressure is generated within the station, drawing in various raw materials from the main conveying pipe 4. Before entering the pneumatic mixing station 6 for final mixing, the raw materials first enter the premixing device 5 with its built-in spiral agitator 56. The raw materials impact the fixed spiral agitator 56 and passively move according to its shape. During this impact and movement, the various raw materials undergo preliminary mixing, i.e., premixing. This effectively improves mixing efficiency and accelerates production. After a certain mixing time, the middle section can be disassembled and cleaned by removing the heavy-duty clamps to ensure the cleanliness of the blades and maintain the premixing effect.

[0022] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
