Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of PVC compound mixing, in particular to an efficient mixing device for PVC compound production. Background Technique
[0002] The mixing process of PVC compound involves two types of key equipment: a high-speed mixer and a low-speed mixer. The primary task of the high-speed mixer is to initially blend PVC powder with various additives, and with its high efficiency, it can quickly achieve the dispersion and mixing of materials. While the low-speed mixer plays the role of deepening the mixing. By extending the mixing time, it ensures that all components reach an extremely uniform distribution.
[0003] Both of these two types of equipment are equipped with advanced temperature control systems to precisely regulate the temperature environment during the mixing process, effectively avoiding quality problems caused by overheating or uneven temperature of the materials. At the same time, supplemented by precise conveying and metering systems, it ensures that each raw material can be fed into the mixer according to the established precise ratio, further guaranteeing the mixing quality.
[0004] However, in practical applications, the PVC compound mixing equipment inevitably faces challenges. After long-term operation, at the bottom of the mixing bin, especially in the area of the discharge port, materials are prone to accumulate and form scale. This phenomenon not only hinders the smooth discharge of materials but may also have a negative impact on the overall mixing efficiency and quality. Therefore, it is particularly important to regularly conduct a thorough cleaning and maintenance of the mixing equipment, which is a key measure to ensure the continuous and efficient operation of the equipment and the stability of the mixing quality. Content of the Utility Model
[0005] The main purpose of the utility model is to provide an efficient mixing device for PVC compound production, which can effectively solve the problems raised in the background technique.
[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0007] An efficient mixing device for PVC compound production includes a PVC mixing cylinder, a feed pipe, a sealing cover, a reducer, a driving motor, a stirring round rod, and a first stirring blade. The sealing cover is located at the upper end of the PVC mixing cylinder. The reducer and the driving motor are installed on the sealing cover. The stirring round rod is located at the center of the end face of the sealing cover and is connected to the output end of the reducer. The first stirring blade is connected to the middle section of the rod of the stirring round rod. The feed pipe is located at the docking port of the PVC mixing cylinder, and the feeding of the PVC mixture is realized through the feed pipe.
[0008] A mixing bin is formed inside the PVC mixing cylinder. The lower end of the PVC mixing cylinder is provided with a bottom cover, and a discharge pipe is installed at the opening on the edge of the end face of the bottom cover. The discharge of the mixture in the mixing bin is realized through the discharge pipe.
[0009] A second stirring blade is installed at the rod end of the stirring round rod, and a steel wire cleaning brush is provided at the lower end of the second stirring blade. The steel wire cleaning brush is used to clean the mixture on the surface of the bottom cover and its openings and prevent scaling, which is beneficial to the discharge of the mixture.
[0010] In a further preferred embodiment of the present utility model, two symmetric connecting frames are provided on the side wall of the PVC mixing cylinder, and an auxiliary material adding pipe is installed at each connecting frame. The addition of auxiliary materials in the mixing bin is realized through the auxiliary material adding pipe;
[0011] In a further preferred embodiment of the present utility model, the sealing cover is fixed on the PVC mixing cylinder by bolts, the bottom cover is hermetically fixed to the PVC mixing cylinder, the reducer is fixed to the sealing cover by bolts, the output end of the driving motor is connected to the reducer, and the driving motor is connected to the sealing cover by bolts;
[0012] In a further preferred embodiment of the present utility model, both the first stirring blade and the second stirring blade are composed of a sleeve and blades. A plurality of blades are annularly distributed on the sleeve, and the sleeve is installed on the stirring round rod through fastening bolts, and the blades are inclined;
[0013] In a further preferred embodiment of the present utility model, the upper end of the bottom cover is a flat surface, the discharge pipe is integrally designed with the bottom cover, and the connection between the discharge pipe and the bottom cover is arc-shaped;
[0014] In a further preferred embodiment of the present utility model, the steel wire cleaning brushes are equidistantly distributed on the second stirring blade, the steel wire cleaning brushes are designed in a "U" shape, and the arc surface of the steel wire cleaning brush contacts the flat inner end surface of the bottom cover.
[0015] Compared with the prior art, the present utility model has the following beneficial effects:
[0016] In the present utility model, the inclined stirring blades strengthen the stirring function, ensure the comprehensive and uniform mixing of the PVC mixture in the PVC mixing cylinder, and greatly improve the mixing efficiency. In addition, to ensure the stable operation of the equipment, regular equipment cleaning and maintenance are crucial. This process includes thoroughly removing residues, checking the fastening components, wear degree and sealing performance of the equipment to ensure that the equipment always maintains the best working state.
[0017] On the other hand, the uniquely designed steel wire cleaning brushes, with their "U" - shaped arrangement and equidistant configuration, enable their arc surfaces to closely fit the inner end plane of the bottom cover.

Detailed Description of the Preferred Embodiment
[0024] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] Embodiment 1
[0026] In Figures 1 to 4 the shown schematic diagram, we introduce an efficient mixing device designed specifically for the production of PVC rubber materials. The device consists of multiple key components, and each component is numbered in detail for easy identification and understanding.
[0027] The PVC mixing cylinder 1, as the core container of the entire device, is equipped with a sealing cover 4 at its top, ensuring the tightness and safety of the mixing process. Not only are the reducer 5 and the drive motor 6 firmly installed on the sealing cover 4, but also the access point for the stirring round rod 9 is cleverly designed. The stirring round rod 9 is located at the center of the sealing cover 4, and the other end is tightly connected to the output shaft of the reducer 5, thus achieving efficient power transmission. In the middle of the stirring round rod 9, we carefully arranged the first stirring blades 10. These blades are fixed to the stirring round rod 9 through sleeves and arranged in an annular array. The inclined design helps to enhance the stirring effect, enabling the PVC mixture to be fully mixed within the PVC mixing cylinder 1.
[0028] The feed pipe 2 is ingeniously arranged at the docking port 3 of the PVC mixing cylinder 1, providing a convenient channel for the addition of PVC mixture. The mixing bin 15 formed inside the PVC mixing cylinder 1 is the stage for the entire mixing process.
[0029] At the bottom of the PVC mixing cylinder 1, we designed a bottom cover 13, and a discharge pipe 14 is installed at the perforated edge. This design enables the smoothly discharging of the materials after mixing. Particularly worth mentioning is that a second stirring blade 11 is installed at the end of the stirring round rod 9, and a wire cleaning brush 12 is additionally arranged below it. These wire cleaning brushes 12 are designed in an equidistant "U" shape, and their arc-shaped surfaces closely adhere to the inner flat surface of the bottom cover 13. They can not only clean the residual mixture on the surface of the bottom cover 13 and its openings during the stirring process but also effectively prevent the occurrence of scaling, thus ensuring the smooth discharge of the mixture.
[0030] In addition, the sealing cover 4, the bottom cover 13, the reducer 5, and the drive motor 6 are all tightly connected to the PVC mixing cylinder 1 or related components by bolts, ensuring the stability and sealing of the equipment structure.
[0031] Embodiment 2
[0032] On the basis of inheriting all the advantages of Embodiment 1, this embodiment further optimizes and expands. In addition to the above core components such as the PVC mixing cylinder 1, the feed pipe 2, the sealing cover 4, the reducer 5, the drive motor 6, the stirring round rod 9, and the first stirring blade 10, two symmetrical connecting frames 7 are additionally arranged on the side wall of the PVC mixing cylinder 1. These two connecting frames 7 are firmly combined with the PVC mixing cylinder 1 by welding, and each is equipped with an auxiliary material adding pipe 8. These auxiliary material adding pipes 8 not only insert into the openings of the connecting frames 7 but also are tightly fixed to the connecting frames 7 by threaded connection, ensuring the accurate addition and sealing of the auxiliary materials. At the same time, the pipe orifices of the auxiliary material adding pipes 8 are directly opposite to the openings on the side wall of the PVC mixing cylinder 1, enabling the auxiliary materials to be directly injected into the mixing bin 15, further improving the flexibility and efficiency of mixing.
[0033] This high-efficiency mixing equipment can not only play an excellent role in mixing in the production of PVC rubber but also flexibly add various auxiliary materials according to actual needs to meet different production requirements.
[0034] Usage process: Ensure that the equipment is in a stable working environment and the power connection is normal. Check the fastening of the PVC mixing cylinder 1 and its various components (sealing cover 4, feed pipe 2, bottom cover 13, stirring round rod 9, first stirring blade 10, second stirring blade 11, wire cleaning brush 12, etc.), and confirm that there is no looseness or damage. Clean the inside of the PVC mixing cylinder 1 to ensure that there is no impurity residue.
[0035] Turn on the power supply and start the drive motor 6. Adjust the rotation speed of the stirring round rod 9 through the speed reducer 5 to an appropriate range to ensure the stirring effect and mixing efficiency.
[0036] Add the main raw material PVC into the mixing bin 15 of the PVC mixing barrel 1 through the feed pipe 2. If auxiliary materials need to be added, they can be directly injected into the mixing bin 15 through the auxiliary material adding pipe 8 (configured in the second embodiment) to ensure full contact between the auxiliary materials and the main raw material.
[0037] Driven by the drive motor 6, the stirring round rod 9 drives the first stirring blade 10 and the second stirring blade 11 to rotate, and performs all-round and high-intensity stirring on the PVC mixture in the mixing bin 15. The first stirring blade 10 with an inclined design helps to enhance the stirring effect and ensure uniform mixing of the mixture. The second stirring blade 11 and the wire cleaning brush 12 below it continuously clean the surface of the bottom cover 13 and its openings during the stirring process to prevent mixture residue and scaling.
[0038] During the mixing process, the rotation speed of the stirring round rod 9 can be adjusted as needed to achieve the best mixing effect. Regularly check the mixing situation to ensure that the mixture is uniform and free of lumps.
[0039] After mixing is completed, open the discharge pipe 14 at the edge of the bottom cover 13 to smoothly discharge the mixed PVC rubber material. During use, pay attention to keeping the discharge pipe 14 unblocked to avoid blockage.
[0040] After mixing is completed, promptly clean the PVC mixing barrel 1 and its various components to remove residues. Regularly check the fastening condition, wear condition and sealing performance of the equipment to ensure that the equipment is in good working condition. This high-efficiency mixing equipment for PVC rubber material can successfully complete the mixing task and provide strong support for the production of PVC rubber material.
