Description

Technical Field

[0001] This utility model belongs to the technical field of open-type rubber mixing mills, specifically an open-type rubber mixing mill for fluororubber processing. Background Technology

[0002] Rubber is divided into natural rubber and synthetic rubber. Fluororubber is a type of synthetic rubber, which refers to synthetic polymer elastomers containing fluorine atoms on the carbon atoms of the main chain or side chains. The introduction of fluorine atoms endows rubber with excellent heat resistance, oxidation resistance, oil resistance, corrosion resistance, and atmospheric aging resistance.

[0003] In the production of fluororubber, an open-face mixing mill is required. This mill consists of two rollers rotating in opposite directions. Due to friction between the roller surfaces and the rubber compound, when the compound comes into contact with the rotating rollers, it is drawn into the gap between the rollers. Steam or cooling water is introduced into the rollers to control their temperature. When steam is introduced, heat is transferred to the rubber compound through the roller walls, raising its temperature, reducing its viscosity, and further improving its plasticity and flowability. This facilitates the dispersion and mixing of compounding agents. After entering the roller gap, the rubber compound is subjected to intense shearing and compression from the two rollers. Under this force, the macromolecular chains in the rubber compound are stretched and broken, and the intermolecular interactions are disrupted, thereby increasing the plasticity and flowability of the rubber compound.

[0004] Generally, rubber mixing mills are open-type designs. When the rubber compound is heated, especially when modified materials are added, it will produce pungent and harmful fumes, which will affect the air quality of the working environment and may also affect the health of the workers. Therefore, in order to address the above problems, an open-type rubber mixing mill for fluororubber processing is proposed. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Specific implementation examples are given below.

[0027] Please see Figure 1 - Figure 5This utility model provides an open-type rubber mixing mill for fluororubber processing, including a main body 1. The main body 1 is equipped with a control panel, which is electrically connected to the electrical components in the device for easy operation. A set of roller side frames 2, made of high-quality steel, are mounted on the main body 1 to support rollers 3. A set of rollers 3 are arranged parallel to each other between two roller side frames 2. A support frame 4 is mounted above the two roller side frames 2, and a [missing information - likely a device or structure] is mounted above the support frame 4. The dual-axis cylinder 5 has a fixed fume treatment mechanism at its output end. The fume treatment mechanism treats the pungent and harmful fumes generated after the rubber compound is heated, so as to avoid affecting the working environment. The fume treatment mechanism includes a treatment housing, which includes an upper housing 6 and a lower housing 7. The upper housing 6 is equipped with an upper fume treatment component, which treats the introduced fumes. The lower housing 7 is equipped with a lower smoke-inducing component, which introduces the pungent and harmful fumes generated after the rubber compound is heated into the treatment housing.

[0028] Furthermore, such as Figure 1 and Figure 4 As shown, the upper shell 6 and the lower shell 7 are integrally formed and connected. The surfaces of the upper shell 6 and the lower shell 7 are provided with anti-corrosion coatings to improve their service life.

[0029] Furthermore, such as Figure 1 and Figure 2 As shown, the lower smoke extraction assembly includes a detachable air duct 8 installed inside the lower housing 7. The air duct 8 has three fan blades. Air ducts 9 are respectively installed on the front and rear sides of the lower housing 7. The arc of the air ducts 9 is directed toward the roller 3 on the same side. When the dual-shaft cylinder 5 is running and the output end of the dual-shaft cylinder 5 is extended to its maximum position, the lower part of the air duct 9 can be placed on the lower part of the corresponding roller 3. When fluororubber is being mixed, the air duct 9 can block the smoke generated during the mixing process. In addition, in conjunction with the use of the air duct 8, it can quickly divert the smoke near the roller 3 to prevent the smoke from spreading to the surroundings.

[0030] Furthermore, such as Figure 1 and Figure 5 As shown, an electrostatic adsorption layer 10 is detachably provided on the inner side of the diversion arc plate 9, which can electrostatically adsorb some larger dust particles onto the electrostatic adsorption layer 10.

[0031] Furthermore, such as Figure 4As shown, the upper flue gas treatment component includes an activated carbon block 11 detachably disposed in the upper housing 6. The activated carbon block 11 has multiple through slots 12 evenly distributed on it. A negative pump 13 is disposed above the support frame 4. The upper housing 6 is connected to the inlet of the negative pump 13 via a connecting pipe 14. A treatment box 15 is disposed on the side of the support frame 4. A conduit 16 is disposed at the outlet of the negative pump 13. The lower end of the conduit 16 extends into the lower inner part of the treatment box 15. The activated carbon block 11 can perform preliminary adsorption treatment on impurities and harmful gases in the drawn flue gas. A specific treatment liquid is added to the treatment box 15. Through the operation of the negative pump 13, the flue gas is drawn from the upper housing 6 to the treatment box 15. The specific treatment liquid in the treatment box 15 treats the harmful substances in the flue gas.

[0032] Furthermore, such as Figure 2 and Figure 3 As shown, a nozzle 17 is provided at the lower end of the conduit 16. Multiple nozzle holes 18 are evenly arranged on the nozzle 17, which forms dense bubbles in the treatment box 15, allowing it to fully contact the treatment liquid and treat the harmful substances in the flue gas.

[0033] Working principle: The pungent and harmful fumes generated after the rubber compound is heated are treated by the fume treatment unit to avoid affecting the working environment;

[0034] Through the structural design of the lower smoke extraction component, the pungent and harmful fumes generated after the rubber compound is heated are introduced into the processing housing. When the dual-shaft cylinder 5 is running and the output end of the dual-shaft cylinder 5 is extended to its maximum position, the lower part of the guide arc plate 9 can be placed under the corresponding roller 3. When fluororubber is being mixed, the guide arc plate 9 can block the fumes generated during the mixing process. On the other hand, in conjunction with the use of the guide air exhaust 8, the fumes near the roller 3 are quickly drawn away to prevent them from drifting to the surroundings. Furthermore, the inner side of the guide arc plate 9 is detachably provided with an electrostatic adsorption layer 10, which can electrostatically adsorb some larger dust particles onto the electrostatic adsorption layer 10.

[0035] The upper flue gas treatment component is designed to treat the introduced flue gas. The flue gas is introduced into the upper housing 6 through the lower smoke inlet component, and the negative pump 13 accelerates the upward extraction of the flue gas. The activated carbon block 11 can perform preliminary adsorption treatment on the impurities and harmful gases in the extracted smoke. A specific treatment liquid is added to the treatment box 15. The negative pump 13 extracts the flue gas from the upper housing 6 into the treatment box 15. The specific treatment liquid in the treatment box 15 treats the harmful substances in the flue gas. A nozzle 17 is set at the lower end of the duct 16. Multiple nozzle holes 18 are evenly arranged on the nozzle 17. The extracted gas forms dense bubbles in the treatment box 15, which can fully contact the treatment liquid and treat the harmful substances in the flue gas.
