Technical Field

[0002] Rubber dispersants, as additives to improve the processing performance of rubber, are usually composed of a variety of chemical components, including surfactants, fillers, polymer modifiers (white flat round particles), etc. In the rubber industry, these dispersants are usually used with other chemicals to achieve the best mixing effect and final product performance. However, the rubber dispersants used may not be completely purified during the preparation process and may contain non-target components and other impurities. In order to improve the quality of rubber products, it is necessary to perform component analysis on the rubber dispersants used.

[0003] In existing technologies, rubber dispersants are usually tested using analytical instruments. This requires taking a sample of the rubber dispersant, placing it in a sampling tube, and then placing the sampling tube into the analytical instrument for testing and analysis. After production, rubber dispersants are usually stored in a ventilated warehouse. However, the open environment can easily allow dust and other contaminants to enter the dispersant, which can affect the analysis results during sampling. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where dust and other contaminants enter the dispersant and affect the analysis results, and to propose a component analysis instrument for rubber dispersants.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An instrument for analyzing the composition of a rubber dispersant includes a working box with analytical components, and further includes: a working cylinder rotatably connected inside the working box, with an opening at the top of the working cylinder, wherein a guide plate is fixedly connected to the inner wall of the working cylinder and the guide plate is spiral-shaped, and an agitation mechanism is provided inside the working cylinder, the agitation end of the agitation mechanism cooperating with the guide plate; and a drive unit provided inside the working box for driving the working cylinder to rotate, wherein when the working cylinder rotates, the agitation end of the agitation mechanism is in the opposite direction to the rotation of the working cylinder.

[0007] To facilitate the agitation of the rubber dispersant, preferably, the agitation mechanism includes a hollow tube rotatably connected to the working box, the hollow tube extending into the working cylinder and provided with a limiting plate, the limiting plate having an air jet hole connected to the hollow tube.

[0008] To make the hollow tube and the rotating shaft rotate in opposite directions, the drive unit further includes a rotating shaft rotatably connected to the working box, the working cylinder being fixedly connected to the rotating shaft, a connecting shaft being rotatably connected inside the working box, the connecting shaft being driven by the rotating shaft through gears, and the hollow tube being driven by the connecting shaft through a pulley.

[0009] To facilitate the rotation of the shaft, a transmission disc is fixedly connected inside the working box. A turbine blade is installed inside the cavity of the transmission disc, which is extended by the connecting shaft. The transmission disc is connected to the hollow tube through a pipe. A negative pressure pump is installed inside the working box, and the output end of the negative pressure pump is fixedly connected to the transmission disc through a pipe.

[0010] To facilitate the delivery of gas into the hollow tube, preferably, a sleeve is fixedly connected inside the working box, the bottom of the hollow tube extends into the sleeve, and the transmission disc is connected to the sleeve through a pipe.

[0011] To facilitate the filtration of the transported gas, preferably, a filter box is fixedly connected inside the working chamber.

[0013] Compared with the prior art, this utility model provides a component analysis instrument for rubber dispersants, which has the following beneficial effects:

[0014] 1. This rubber dispersant is used in a component analysis instrument. Through the combination of a guide plate and a limiting plate, the rubber dispersant can be continuously collided inside the working cylinder, and impurities or dust on the rubber dispersant can be collided. Then, the dust or impurities are blown away in a spiral pattern through the air jet. On the one hand, this can effectively increase the dispersion effect of the rubber dispersant. On the other hand, the air jet also helps to remove foreign matter and impurities adhering to the surface of the particles. Therefore, the analysis results will not be affected during sampling, and the purity of the raw materials is optimized.

[0015] 2. This rubber dispersant can be used with component analysis instruments. Through the filter screen, impurities in the air entering or leaving the filter box can be intercepted and filtered, and dust can be collected.

[0016] The parts of this device not covered are the same as or can be implemented using existing technology. On the one hand, this utility model can effectively increase the dispersion effect of rubber dispersant. On the other hand, air jetting also helps to remove foreign matter and dust adhering to the surface of particles, so that the analysis results will not be affected during sampling, thus optimizing the purity of raw materials.

[0027] In addition, a working cylinder 3 is rotatably connected inside the working box 1, and an opening is formed at the top of the working cylinder 3 so that the rubber dispersant can be put into the working cylinder 3.

[0028] Furthermore, the aforementioned stirring mechanism includes a hollow tube 7 rotatably connected to the working box 1, the hollow tube 7 extending into the working cylinder 3 and provided with a limiting plate 8, the limiting plate 8 having an air jet hole 9, the air jet hole 9 being connected to the hollow tube 7.

[0029] Gas can be transported into the limiting plate 8 through the hollow tube 7. The limiting plate 8 is provided with a flow cavity, which is connected to the hollow tube 7 and the jet hole 9.

[0030] Furthermore, a drive unit is provided inside the working box 1 to drive the working cylinder 3 to rotate. When the working cylinder 3 rotates, the hollow tube 7 rotates in the opposite direction to the working cylinder 3.

[0032] Reference Figure 2 When the connecting shaft 12 rotates, the connecting shaft 12 will drive the rotating shaft 11 to rotate through the gear. During this process, the connecting shaft 12 will also drive the hollow tube 7 to rotate through the pulley, so that the rotation direction of the connecting shaft 12 and the hollow tube 7 is opposite.

Then, the dust or impurities are blown away in a spiral pattern through the jet hole 9. On the one hand, this can effectively increase the dispersion effect of the rubber dispersant.
