Description

Technical Field

[0001] The utility model belongs to the technical field of antibacterial agent doping, and particularly relates to an antibacterial agent doping device for producing polyurethane elastomer. Background Art

[0002] At present, with the increasing emphasis on health and environmental protection, polyurethane elastomer, as a core material in multiple industries, the improvement of its performance and functionality is crucial. To cope with the complexity of the environment, various antibacterial agents, such as silver ions, zinc oxide, etc., are doped in polyurethane to inhibit the growth of microorganisms, comprehensively cover all microorganisms, and by adding multiple antibacterial agents and utilizing their synergistic effects, the antibacterial performance of polyurethane elastomer is improved while maintaining its original performance advantages.

[0003] In the current production process of polyurethane elastomer, various antibacterial agents are often directly injected into the production equipment through pipelines for mixing treatment. However, this production method has significant defects: the antibacterial agents can only be mixed inside the production equipment, which not only limits the full fusion of the antibacterial agents and polyurethane raw materials, but also affects the doping and mixing effect in the subsequent production process, resulting in an unsatisfactory doping effect of the antibacterial agents, thereby affecting the overall antibacterial performance and production efficiency of the polyurethane elastomer.

[0004] Therefore, it is very necessary to invent an antibacterial agent doping device for producing polyurethane elastomer. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides an antibacterial agent doping device for producing polyurethane elastomer, which includes a pretreatment doping outer shell, pipe seats, an air pump, an upper spiral blade, a lower spiral blade, a feed pipe, a pipe orifice, and a discharge pipe orifice. Two of the pipe seats are fixedly installed on the pretreatment doping outer shell, the air pump is fixedly installed on the pipe seats, the upper spiral blade and the lower spiral blade are fixedly installed inside the pretreatment doping outer shell, and the pretreatment doping outer shell is communicated with the feed pipe through the pipe orifice; the discharge pipe orifice is fixedly installed below the pretreatment doping outer shell;

[0006] The discharge pipe orifice is communicated with the polyurethane elastomer production equipment through a pipeline; the feed pipe is communicated with the antibacterial agent storage tank through a pipeline.

[0007] Preferably, the pretreatment doping outer shell is distributed with a cylindrical part and a conical part, and the pipe seats are respectively fixedly installed tangentially on the cylindrical part and the conical part, and the output end of the air pump is tangentially communicated with the pretreatment doping outer shell through the pipe seats.

[0008] Preferably, the upper spiral blade is fixedly installed on the inner wall of the cylindrical part of the pretreatment doping outer shell, and the lower spiral blade is fixedly installed on the conical part of the pretreatment doping outer shell, and the lower spiral blade is a conical spiral blade.

[0009] Preferably, the connection between the pre-treatment doping housing and the socket and the nozzle is arranged between the pitches of the upper helical blade or the lower helical blade, and the upper helical blade and the lower helical blade do not affect the medium transported inside the socket and the nozzle from entering.

[0010] Preferably, there is an included angle between the nozzle and the pre-treatment doping housing, the nozzle is inclined, and the injection pipe is a multi-way branch pipe structure.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model abandons the traditional way of directly injecting antibacterial agents for doping, and instead adopts an innovative up-and-down pneumatic spiral treatment mode. This design cleverly realizes the triple mixing treatment of pre-mixing, preliminary mixing and overall mixing of various different antibacterial agents (solids), greatly improving the high-efficiency mixing effect of antibacterial agents inside the subsequent production equipment. Through this treatment method, the utility model effectively avoids the problem of unsatisfactory doping effect, thereby ensuring that the polyurethane elastomer has excellent antibacterial properties.

[0019] As shown in the attached Figure 1 to the attached Figure 2 figures:

[0020] An antibacterial agent doping device for the production of polyurethane elastomers provided by the present invention includes a pretreatment doping outer shell 1, a pipe seat 2, an air pump 3, an upper spiral blade 4, a lower spiral blade 5, a feeding pipe 6, a pipe orifice 7, and a discharge pipe orifice 8. Two pipe seats 2 are fixedly installed on the pretreatment doping outer shell 1, and the air pump 3 is fixedly installed on the pipe seat 2. The upper spiral blade 4 and the lower spiral blade 5 are fixedly installed inside the pretreatment doping outer shell 1. The pretreatment doping outer shell 1 is communicated with the feeding pipe 6 through the pipe orifice 7; the discharge pipe orifice 8 is fixedly installed below the pretreatment doping outer shell 1.

[0021] The discharge pipe orifice 8 is communicated with the polyurethane elastomer production equipment through a pipeline; the feeding pipe 6 is communicated with the antibacterial agent storage tank through a pipeline.

[0022] Embodiment 1:

[0023] Specifically, the pretreatment doping outer shell 1 is distributed with a cylindrical part and a conical part. The pipe seats 2 are fixedly installed tangentially on these two parts respectively, ensuring that the output end of the air pump 3 can be tangentially communicated with the pretreatment doping outer shell 1 through the pipe seat 2. Such a design enables the air pump 3 to provide a stable air flow into the pretreatment doping outer shell 1, thereby providing effective power support for the subsequent antibacterial agent mixing process. Through this structural configuration, the present invention can achieve the pre-mixing, preliminary mixing, and overall mixing of various antibacterial agents, laying a good foundation for the subsequent production process.

[0024] Specifically, on the inner wall of the cylindrical part of the pre-treatment doping housing 1, upper helical blades 4 are fixedly installed. These helical blades can rotate along with the movement of the air flow, thereby pre-mixing the antibacterial agent entering the cylindrical part. At the same time, lower helical blades 5 are fixedly installed on the conical part of the pre-treatment doping housing 1. These helical blades are conical and fit the shape of the conical part, which can further perform primary mixing and overall mixing on the pre-mixed antibacterial agent. This design enables the antibacterial agent to be fully mixed and dispersed before entering the production equipment, thus ensuring a more ideal doping effect in the subsequent production process.

[0025] Specifically, the connection between the pre-treatment doping housing 1 and the pipe seat 2 and the pipe orifice 7 is cleverly set between the pitches of the upper helical blades 4 or the lower helical blades 5. Such a design ensures that the upper helical blades 4 and the lower helical blades 5 do not obstruct the flow of the medium (such as the antibacterial agent) entering through the pipe seat 2 and the pipe orifice 7 when rotating. Therefore, the antibacterial agent can smoothly enter the pre-treatment doping housing 1 and be pre-mixed, primarily mixed, and overall mixed under the action of the helical blades, thereby improving the doping effect and mixing efficiency in the subsequent production process.

[0026] Specifically, there is an included angle between the pipe orifice 7 and the pre-treatment doping housing 1. The pipe orifice 7 is inclined, which helps to optimize the injection angle and flow direction of the antibacterial agent, enabling the antibacterial agent to be more evenly distributed when entering the pre-treatment doping housing 1. The injection pipe 6 has a multi-pass branch pipe structure, allowing different types of antibacterial agents or other additives to be injected simultaneously from multiple branch pipes, greatly improving the operation flexibility and efficiency. The multi-pass branch pipe structure also ensures that various antibacterial agents can maintain a certain ratio and speed during injection, further promoting the uniform mixing of the antibacterial agent within the pre-treatment doping housing 1.

[0027] Example Two:

[0028] First, when the antibacterial agent enters the cylindrical part of the pretreatment doping housing 1 through the injection pipe 6, due to the inclined setting of the pipe orifice 7 and the multi-pass branch pipe structure, the antibacterial agent can be evenly distributed. At the same time, the upper spiral blade 4 on the inner wall of the cylindrical part further guides the antibacterial agent and the air flow generated by the upper air pump 3 to preliminarily stir and mix the antibacterial agent, realizing the pre-mixing treatment. The pre-mixed antibacterial agent continues to move towards the conical part of the pretreatment doping housing 1. The lower spiral blade 5 of the conical part is conical and fits the shape of the conical part, which can further stir and mix the antibacterial agent to achieve the preliminary mixing treatment. During this process, as the range of movement of the antibacterial agent in the conical part becomes smaller and smaller, the antibacterial agents will be further mixed. Subsequently, the lower air pump 3 starts to work for the full mixing treatment. This two-way air flow can more effectively promote the mixing of the antibacterial agent in the pretreatment doping housing 1. The upper air pump 3 pushes the antibacterial agent downward, while the lower air pump 3 lifts the antibacterial agent upward, forming a circulating flow, thereby enhancing the mixing effect. The lower air pump 3 can prevent the antibacterial agent from depositing at the bottom of the pretreatment doping housing 1, while the upper air pump 3 helps to remix the antibacterial agent at the top of the pretreatment doping housing 1. This design helps to maintain the uniform distribution of the antibacterial agent in the pretreatment doping housing 1 and prevent the antibacterial agent from depositing and caking. After the full mixing treatment is completed, the antibacterial agent enters the polyurethane elastomer production equipment through the discharge pipe orifice 8 and is mixed with the polyurethane raw material to finally produce a polyurethane elastomer with antibacterial function.

[0029] Using the technical solution of the present invention, or those skilled in the art being inspired by the technical solution of the present invention to design a similar technical solution and achieving the above technical effects shall fall within the protection scope of the present invention.
