Description

Technical Field

[0001] This utility model belongs to the field of rubber additive processing technology, and in particular relates to a rubber additive anti-ozone agent mixing device. Background Technology

[0002] Rubber is a product with very wide applications in industry. Based on its source, rubber is divided into synthetic rubber and natural rubber.

[0003] Rubber products are inexpensive, economical, and environmentally friendly, but they also have fatal flaws, such as being prone to oxidation and aging. Therefore, current technologies often add additives, including antioxidants, to the rubber during processing to improve its performance. Adding additives increases the rubber's antioxidant capacity and extends its service life. The most common additive is the addition of anti-ozone oxidation additives.

[0004] Therefore, the formulation of anti-ozone oxidation auxiliaries during rubber production is a key production step to improve the quality of rubber products. Specifically, the anti-ozone agent is first synthesized into a polymer emulsion in a reactor. Subsequently, the polymer emulsion needs to be mixed with other auxiliaries, including release agents, dispersants, and fillers. The uniformity of the mixture is crucial to improving the effectiveness of the anti-ozone agent.

[0005] Specifically, because polymeric emulsions have very high viscosity, when added to a material system, they quickly form particles with the solids. This particle formation makes it difficult for the polymeric emulsion to be uniformly mixed into the material system.

[0006] Furthermore, during the polymerization process, the bottom layer of the emulsion in viscous materials often contains incompletely dissolved and dispersed emulsion precipitates forming lumps (which is also one of the factors leading to insufficient subsequent mixing). Therefore, existing technologies often require filtering the emulsion once. Thus, in the production process, achieving simultaneous mixing and filtering during the mixing process would greatly improve efficiency (i.e., enabling slow emulsion feeding while coordinating with mixing and stirring to avoid concentrated emulsion discharge). However, current equipment struggles to achieve simultaneous mixing and filtering. Utility Model Content

[0007] Based on the above background, the purpose of this utility model is to provide a rubber additive anti-ozone agent mixing device.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A rubber additive anti-ozone agent mixing device includes a solid material mixing cylinder, wherein a filter material mechanism is fixedly installed inside the cylinder opening.

[0010] The filter media mechanism includes an annular filter disc body, with a through hole in the center of the annular filter disc body, and an annular baffle flange fixedly connected to the edge of the through hole.

[0011] The annular filter disc has several filter media holes. The mixing device also includes a solid material stirring mechanism, which includes a material shaft rotatably connected inside the solid material mixing cylinder. Several impinging plates are fixedly connected to the upper end of the material shaft. The material enters the solid material mixing cylinder through the filter media holes and is dispersed by the impinging plates.

[0012] Preferably, the top of the annular filter disc is threadedly connected to an annular top cover, and the top of the annular top cover is connected to a pump material pipe;

[0013] The annular top cover has a central hole at its center that is adapted to an annular retaining flange, and the annular retaining flange is limited within the central hole;

[0014] The solid material mixing mechanism also includes a motor cover that is fixedly installed inside the annular retaining flange.

[0015] Preferably, a motor is mounted on the top of the motor cover, and the output end of the motor is fixedly mounted on the material shaft.

[0016] Preferably, the longitudinal cross-sectional shape of the impingement plate is a right triangle, and the inner end of the impingement plate is welded to the upper end of the side wall of the material shaft.

[0017] Preferably, a plurality of solid material stirring structures are installed on the material shaft, and the solid material stirring structures are located below the material shaft.

[0018] Preferably, the solid material mixing structure includes several inclined stirring frames that are inclined toward the material shaft, and type I mixing structure and type II mixing structure are installed on the inclined stirring frames.

[0019] Preferably, the type I mixing structure is distributed on the sidewalls of both sides of the inclined agitator;

[0020] The type II mixing structure is located on the outer side wall of the inclined stirring rack.

[0021] Preferably, the type I mixed structure includes a plurality of rods;

[0022] The type II mixing structure includes a toothed plate arranged perpendicular to the inclined stirring frame, and the toothed plate has a number of curved convex tooth structures integrally formed.

[0023] Preferably, an upper connecting rod and a lower connecting rod are respectively installed at the upper and lower ends of the inclined stirring frame, and the upper connecting rod and the lower connecting rod are fixedly installed on the material shaft.

[0024] This utility model has the following beneficial effects:

[0025] 1. During operation, the pump feed pipeline is connected to an external feed pipeline, and the emulsion enters the annular filter disc. Under gravity, it is filtered through the filter media holes, while the precipitates in the emulsion are retained. Simultaneously, the emulsion is dispersed and fed into the solids mixing cylinder while the emulsion is being filtered through the filter media holes.

[0026] 2. Several impellers (near the bottom of the filter media holes) are fixedly connected to the upper end of the feed shaft. The emulsion enters the solid mixing cylinder through the filter media holes and is dispersed by the impellers. When the emulsion is added, it enters the solid mixing cylinder. Due to the rotation and stirring of the feed shaft, the impellers rotate, and the emulsion impacts the impellers and is dispersed again by being "impacted" and added to the system, thus further improving the mixing effect.

[0027] 3. The Type I mixing structure includes several rods; the rod structure design aims to improve mixing while reducing mixing resistance. Simultaneously, to further improve the mixing effect, the aforementioned Type II mixing structure includes a toothed plate perpendicular to the inclined stirring frame, with several curved convex teeth integrally formed on the toothed plate. The toothed plate structure aims for fine mixing; specifically, the spacing between the rods determines the amount of mixing. Therefore, the rods mainly serve as coarse stirrs for the material system, used to fully disperse the materials. The fine stirring of the toothed plate improves the mixing uniformity. Furthermore, the convex teeth (semi-circular in shape) also serve to further refine and disperse the materials. Attached Figure Description

[0039] Example 1

[0040] like Figure 1-6 As shown, a rubber additive anti-ozone agent mixing device includes a solid material mixing cylinder 1, and a filter material mechanism is fixedly installed inside the cylinder opening of the solid material mixing cylinder 1. Similar to existing methods, a discharge structure (such as a material pipe with a valve to control the discharge) is installed at the bottom of the solid material mixing cylinder 1.

[0041] Specifically, the filter media mechanism includes an annular filter disc 21, which is detachably mounted on the inner wall of the solid material mixing cylinder 1 (facilitating subsequent disassembly and cleaning, as well as the addition of solid material; specifically, the solid material is added beforehand, and then the annular filter disc 21 is tightened). This is achieved by creating a threaded structure on the inner wall of the solid material mixing cylinder 1 and a threaded structure on the outer wall of the annular filter disc 21, thus facilitating subsequent assembly.

[0042] Meanwhile, a through hole is provided in the center of the annular filter disc 21, and an annular baffle flange 22 is fixedly connected to the edge of the through hole; a number of filter media holes 211 are provided on the annular filter disc 21. The filter media holes 211 are arranged in the area between the annular baffle flange 22 and the side wall of the annular filter disc 21.

[0043] The mixing device also includes a solid material stirring mechanism, which includes a material shaft rotatably connected inside the solid material mixing cylinder 1 (in conventional methods, a bearing base rotatably connected to the material shaft is installed at the bottom inside the solid material mixing cylinder 1). The solid material stirring mechanism also includes a motor cover 32 fixedly installed inside the annular retaining flange 22. A motor 31 is installed on the top of the motor cover 32, and the material shaft is fixedly installed at the output end of the motor 31. In conventional methods, the motor 31 is fixedly installed, for example, by bolting it to the motor cover 32.

[0044] Specifically, in the existing configuration, the motor 31 is fixed to the top of the motor cover 32. The output shaft of the motor 31 is connected to a central connecting shaft A via a coupling, and the connecting shaft A is fixed to the material shaft via a flange B. This configuration facilitates simultaneous disassembly of the annular filter disc 21, as the motor 31 is disassembled along with it. In other words, the motor output shaft can be directly disconnected from the central connecting shaft A.

[0045] Meanwhile, the top of the annular filter disc 21 is threadedly connected to an annular top cover 23 (specifically, the inner side wall of the annular filter disc 21 has a threaded structure, and the outer side wall of the annular top cover 23 has a matching threaded structure, which facilitates the disassembly of the annular top cover 23 and the cleaning of the blockage after filtration), and the top of the annular top cover 23 is connected to a pump material pipe.

[0046] Furthermore, the center of the annular top cover 23 has a central hole that matches the annular retaining flange 22. The annular retaining flange 22 is limited within the central hole. That is, when the annular top cover 23 is screwed in, the central hole of the annular top cover 23 gradually descends and is engaged with the outer side wall of the annular retaining flange 22 (while the motor cover 32 is fixed on the inner side wall of the annular retaining flange 22).

[0047] During operation, the pump material pipeline 231 is connected to the external supply pipeline in the existing manner, and the emulsion enters the annular filter disc 21 along with the emulsion. Under the action of gravity, the emulsion is filtered through the filter material holes 211, and the precipitates in the emulsion are retained.

[0048] Because the filter media pores 211 are involved in filtering the emulsion, the emulsion is simultaneously filtered and the emulsion is fed into the solid mixing cylinder 1 in a dispersed manner.

[0049] Example 2

[0050] like Figure 1-6As shown, in this embodiment, based on the structure of embodiment 1, in order to further facilitate the addition of emulsion dispersion to the system during operation, several impellers 5 (close to the bottom of the filter material hole 211) are fixedly connected to the upper end of the material shaft. The material is filtered from the filter material hole 211 into the solid material mixing cylinder 1 and dispersed by the impellers 5.

[0051] When the emulsion is added, it enters the solid mixing cylinder 1. Due to the rotation and stirring of the material shaft, the impeller 5 rotates, and the emulsion is "bombarded" and dispersed into the system after hitting the impeller 5, thereby further improving the mixing effect.

[0052] The longitudinal cross-sectional shape of the aforementioned impingement plate 5 is a right-angled triangle, and the inner end of the impingement plate 5 is welded to the upper end of the side wall of the material shaft.

[0053] Example 3

[0054] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 2, in order to improve the mixing effect, a number of solid material stirring structures 33 are installed on the material shaft, and the solid material stirring structures 33 are located below the material shaft.

[0055] Specifically, the solid material mixing structure 33 includes several inclined stirring frames 331 that are inclined towards the material axis (the inclined stirring frame 331 is 1.5m long, 10cm wide, and 0.8mm thick. It is formed by cutting steel frame as blank material and has great structural strength, so it can fully mix the material system composed of solid, emulsion and liquid systems).

[0056] Specifically, an upper connecting rod and a lower connecting rod 334 are respectively installed at the upper and lower ends of the inclined stirring frame 331, and the upper connecting rod and the lower connecting rod 334 are fixedly installed on the material shaft. Specifically, a lower connecting seat 335 is fixedly connected to the lower end of the material shaft, and the lower connecting rod 334 is welded to the lower connecting seat 335. Several upper protrusions are fixedly connected to the upper end of the material shaft, and the upper connecting rods are welded to the upper protrusions.

[0057] Example 4

[0058] like Figure 1-6 As shown, in order to enhance the mixing effect, this embodiment is based on the structure of embodiment 3. In addition, the inclined stirring frame 331 is equipped with a type I mixing structure and a type II mixing structure.

[0059] Specifically, type I mixing structures are distributed on the side walls of the inclined stirring frame 331 on both sides symmetrically; type II mixing structures are located on the side walls of the inclined stirring frame 331 facing outward.

[0060] The type I mixing structure includes several rods 332; the design of the rods 332 is intended to improve mixing while reducing mixing resistance.

[0061] Meanwhile, in order to further improve the mixing effect, the above-mentioned type II mixing structure includes a toothed plate 333 (the length of the toothed plate 333 is slightly shorter than that of the inclined stirring frame 331) which is perpendicular to the inclined stirring frame 331. Several curved convex tooth structures are integrally formed on the toothed plate 333.

[0062] The toothed plate 333 is designed for fine mixing. Specifically, the spacing between the rods 332 determines the mixing process. Therefore, the rods 332 primarily serve as coarse mixers for the material system, thoroughly dispersing the materials. The fine mixing of the toothed plate 333 further enhances the uniformity of the mixture. The convex tooth structure (semi-circular in shape) also contributes to the fine dispersion of the materials.

[0063] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
