Description

Technical Field

[0001] The utility model relates to the field of industrial automation equipment, and more particularly to a mixing and batching device. Background Art

[0002] During the pipe production process, multiple plastic materials, such as PVC, PE, and CPE, are typically mixed in specific proportions to produce plastic pipes that meet performance requirements. These materials require precise metering and mixing during various steps to ensure the quality and physical properties of the pipes.

[0003] Existing mixing and batching equipment for pipe production has several shortcomings. For example, low metering accuracy leads to large errors in the batching ratio, affecting the physical properties of the pipe. Material transportation easily generates dust pollution, which not only affects the production environment but also leads to material waste. Furthermore, insufficient uniformity in the mixing of different raw materials can lead to unstable pipe quality during use, such as breakage and leakage.

[0004] Therefore, designing a mixing and batching device that can accurately measure, evenly mix and reduce dust pollution is crucial to improving pipe production efficiency and quality. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a mixing and batching device that can effectively solve the problems of the prior art. The device is particularly suitable for mixing and batching plastic materials in pipe production, and has the characteristics of accurate metering, uniform mixing and effective dust removal.

[0006] To achieve the above objectives, the present invention provides the following technical solutions, which mainly include:

[0007] A mixing and batching device includes multiple silos, a measuring scale, a discharge valve, a sealing silo, a dust removal mechanism, a three-way steering valve, a three-way pipeline, a mixing pot, a three-way switching valve, a suction pipeline, a small material weighing machine and a negative pressure suction mechanism.

[0008] The silos are used to store various types of plastic powder materials, such as PVC, PE, and CPE. Each silo is connected to a discharge valve via a scale for precise material weighing. The discharge valve is connected to a sealed bin for temporary storage of weighed materials and to prevent leakage. A dust removal mechanism is located above the sealed bin to remove dust generated during the metering and conveying processes, ensuring a clean production environment.

[0009] A three-way diverter valve is connected to the lower portion of the sealed silo, directing materials into different three-way pipelines. These pipelines convey materials to multiple mixing tanks, which are used to evenly mix the various materials. A three-way switching valve is installed at the inlet of each mixing tank to selectively control the flow of materials into a specific mixing tank.

[0010] Preferably, the device also includes an independent small material weighing machine for individually measuring small materials that require precise control and conveying the small materials to the mixing pot via a negative pressure suction mechanism. The negative pressure suction mechanism is connected to the system via a suction pipe and is used to generate negative pressure to suck and convey the powdered material.

[0011] It can be seen from the above technical solutions that compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) Accurate metering: By setting up multiple silos and metering scales, this device can accurately measure different types of plastic powder materials (such as PVC, PE, CPE, etc.), ensuring that each material is mixed according to the set ratio, thereby improving the quality stability of the pipe products.

[0013] (2) Uniform mixing: This device uses multiple mixing pots and a three-way piping system to ensure that different materials are evenly distributed during the mixing process, avoiding differences in pipe performance caused by uneven mixing and improving the durability and consistency of the product.

[0014] (3) Efficient dust removal: The dust removal mechanism in the device effectively reduces dust pollution, keeps the production environment clean, reduces the impact of dust on equipment and production personnel, and ensures the environmental protection and safety of the production process.

[0015] (4) High flexibility: By setting up a three-way steering valve and a three-way switching valve, the device can flexibly control the conveying paths of different materials, adapt to the production needs of various pipe formulas, and has high adaptability and operability.

[0016] (5) Negative pressure conveying: The use of a negative pressure suction mechanism ensures the efficient transmission of materials during the conveying process, while avoiding the leakage and waste of materials, further improving production efficiency and material utilization.

[0017] (6) Adapting to the diverse needs of pipe production: The utility model is particularly suitable for mixing and proportioning a variety of plastic materials required in the pipe production process, and can meet the production needs of pipes of different types and specifications, thereby improving the production capacity and market competitiveness of the enterprise.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figure 1 As shown, a mixing and batching device includes multiple silos 1, a weighing scale 2, a discharge valve 3, a sealing bin 4, a dust removal mechanism 5, a three-way steering valve 6, a three-way pipeline 7, a mixing pot 8, a three-way switching valve 9, a suction pipeline 10, a small material weighing machine 11 and a negative pressure suction mechanism 12.

[0024] The silos 1 are used to store various types of plastic powder materials, such as PVC, PE, and CPE. Each silo 1 is connected to a discharge valve 3 via a weighing scale 2, which accurately weighs the materials. The discharge valve 3 is connected to a sealed silo 4, which temporarily stores the weighed materials and prevents leakage. A dust removal mechanism 5 is located above the sealed silo 4 to remove dust generated during the metering and transportation processes, ensuring a clean production environment.

[0025] A three-way diverter valve 6 is connected to the lower portion of the sealed bin 4, directing materials to different three-way pipes 7. These pipes transport the materials to multiple mixing pots 8, which are used to evenly mix the various materials. A three-way switching valve 9 is installed at the inlet of each mixing pot 8 to selectively control the entry of materials into a specific mixing pot 8.

[0026] Preferably, the device further includes an independently arranged small material weighing machine 11 for individually measuring small materials that require precise control, and conveying the small materials to the mixing pot 8 through a negative pressure suction mechanism 12. The negative pressure suction mechanism 12 is connected to the system through a suction pipe 10, and is used to generate negative pressure to suck and convey powder materials.

[0027] The mixing and batching device of this utility model is used to accurately measure and mix the various powder materials required for the production of plastic pipes. The following describes in detail the application process of this device in actual production:

[0028] 1. Raw material storage and preliminary processing:

[0029] During the production process, powder materials such as polyvinyl chloride (PVC), polyethylene (PE), and chlorinated polyethylene (CPE) are stored in multiple silos 1. Each silo is connected to a scale 2, which accurately measures the weight of each raw material. The scale accurately weighs each material according to the set ratio, ensuring that each material in the mixture meets the process requirements.

[0030] 2. Material discharge and sealed storage:

[0031] After metering, the material is discharged through discharge valve 3 and temporarily stored in sealed bin 4. The sealed bin design effectively prevents leakage during the discharge process, ensuring the purity of the material. To reduce the impact of dust on the environment, a dust removal mechanism 5 is installed above the sealed bin to effectively capture and filter dust generated during the material discharge process, ensuring a clean production environment.

[0032] 3. Material diversion and transportation:

[0033] The material discharged from the sealed bin enters the three-way diverter valve 6, which selects the appropriate conveying path through the three-way diverter valve, and conveys different types of powder materials to their respective three-way pipes 7. The three-way pipes convey the materials to multiple mixing pots 8, each of which is used to evenly mix the incoming materials to ensure the uniformity and stability of the mixture.

[0034] 4. Accurate measurement and addition of small ingredients:

[0035] In addition to the main raw materials, small ingredients (such as additives and stabilizers) also require precise metering. These small ingredients are individually weighed using a small ingredient weighing machine 11 and then drawn into the mixing pot 8 via a negative pressure suction mechanism 12. This mechanism prevents leakage during the conveying process, further improving the quality and consistency of the mixture.

[0036] 5. Output and application of mixed materials:

[0037] The evenly mixed material is transported to the next process on the production line, such as extrusion or injection molding, via the three-way switching valve 9 and the material intake pipe 10. The three-way switching valve allows the mixing kettle to be flexibly connected to different production equipment to meet the production requirements of different pipe specifications, ensuring the continuity and flexibility of the production process.

[0038] Through the above implementation process, the mixing and batching device of the utility model achieves precise metering and efficient mixing of multiple plastic materials in pipe production, greatly improving production efficiency and ensuring consistent product quality. In addition, the application of the dust removal mechanism effectively reduces dust pollution, improves the production environment, and meets modern environmental protection requirements.

[0039] This embodiment shows that the application of the utility model in pipe production has significant advantages, can meet the production needs of different types of plastic pipes, and bring good economic benefits to enterprises.

[0040] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
