[0026] The following describes in detail, with reference to the accompanying drawings, a low-dust sulfur vulcanizing agent oil-filled stirring device according to an embodiment of the present invention.

[0027] Example

[0028] For easier understanding, please refer to Figures 1 to 4 An embodiment of a low-dust sulfur vulcanizing agent oil-filled stirring device provided by this utility model includes a stirring tank 1, a dust filter and breathable mesh 20 disposed on the side wall of the stirring tank 1, a top cover 2, and a drive motor 3 installed on the top of the top cover 2. The inlet of the stirring tank 1 is provided with a double-layer sealing assembly.

[0029] The double-layer sealing assembly includes a first sealing layer 7, a sealing cap 8, a mounting plate 10, a flip-up arc-shaped cap 12, and a sealing strip 19. The first sealing layer 7 is disposed on the inner wall of the mixing tank 1 and located on the inner wall support ring of the mixing tank 1. The sealing cap 8 is fitted into a hole opened in the first sealing layer 7. The mounting plate 10 is fixedly connected to one side of the top cover 2. The flip-up arc-shaped cap 12 is rotatably connected to the top of the mixing tank 1 through a mounting member 11, and the flip-up arc-shaped cap 12 has an arc-shaped structure that fits against the end faces of the mounting plate 10 and the sealing strip 19. The first sealing layer 7 divides the interior of the mixing tank 1 into a feeding chamber and a mixing chamber.

[0030] The outer wall of the mixing tank 1 is provided with a negative pressure dust removal assembly, which includes a shaft seal exhaust fan 14 and a negative pressure dust removal pipe. The shaft seal exhaust fan 14 is fixedly installed on the outer wall of the mixing tank 1, and one output end of the shaft seal exhaust fan 14 is connected to the interior of the mixing tank 1. The negative pressure dust removal pipe is fixedly installed on the input end of the shaft seal exhaust fan 14, and the other end of the negative pressure dust removal pipe is installed on one end of the flip-up arc-shaped cover 12 and passes through it.

[0031] It should be noted that the mixing tank 1 has a cylindrical structure, with a removable top cover 2 fixed to the top by bolts. A drive motor 3 is installed at the center of the top of the top cover 2, and the output shaft of the drive motor 3 extends vertically into the mixing tank 1, with a stirring shaft 4 fixed to the end of the output shaft. The stirring shaft 4 is axially spaced with first mixing blades 5 and second mixing blades 6. The first mixing blades 5 are helical blades, and the second mixing blades 6 are paddle blades; their combination achieves efficient mixing of the sulfur vulcanizing agent and the oil. A discharge pipe 18 is connected to one side of the bottom of the mixing tank 1, and the discharge pipe 18 is equipped with a valve to control the discharge.

[0032] The double-layer sealing assembly consists of a first sealing layer 7, a sealing cover 8, a mounting plate 10, a flip-up arc-shaped cover 12, and a sealing strip 19. The dust filter and breathable mesh 20 is a commonly used filter mesh and can be detachably installed on the outer wall of the mixing tank 1.

[0033] The first sealing layer 7 is positioned and fixed by the inner wall support ring of the mixing tank 1, the top cover 2 can be disassembled from the mixing tank 1, and the first sealing layer 7 is movable on the outer wall of the stirring shaft 4. Therefore, the first sealing layer 7, the stirring shaft 4, the first mixing blade 5, and the second mixing blade 6 can be installed and removed from the mixing tank 1.

[0034] The sealing cap 8 is fitted into the hole of the first sealing layer 7, and the sealing ring 9 (such as silicone material) is circumferentially fixed to its side wall. The sealing cap 8 forms a first-level seal with the first sealing layer 7 by manual pressing, and the sealing ring 9 is deformed under pressure to enhance airtightness.

[0035] The flip-up arc-shaped cover 12 is hinged to the side wall of the mixing tank 1 via the mounting member 11. The mounting member 11 is a fixed seat with a rotating shaft. The flip-up arc-shaped cover 12 is semi-circular, and its curvature matches the outer contour of the mounting plate 10. When the flip-up arc-shaped cover 12 is closed, its inner arc surface fits against the outer surface of the mounting plate 10, and a second-level seal is formed by the edge-embedded sealing strip 19 (such as a polyurethane strip).

[0036] The negative pressure dust removal assembly includes a shaft seal exhaust fan 14 and a negative pressure dust removal pipe:

[0037] Shaft seal exhaust fan 14: fixed to the outer wall of the mixing tank 1 near the top, and its air outlet is connected to the inside of the mixing tank 1 through a pipe.

[0038] The sealing strip 19 of the flip-up arc-shaped cover 12 is a flexible rubber sealing strip, and the corresponding position of the mounting plate 10 is sealed with a tight seal by the flexible rubber sealing strip.

[0039] In an optional embodiment: a sealing ring 9 is fixedly connected to the side wall of the sealing cover 8, and the sealing cover 8 is sealed in the corresponding hole on the first sealing layer 7 by the sealing ring 9.

[0040] It should be noted that the sealing cap 8 is made of polytetrafluoroethylene, and its edge has an annular groove for embedding the sealing ring 9. The sealing ring 9 has a trapezoidal cross section, and when under pressure, it forms a surface contact seal with the inner wall of the hole in the first sealing layer 7.

[0041] In an optional embodiment, a handle 13 is provided on one end face of the flip-up arc-shaped cover 12.

[0042] It should be noted that the outer end of the flip-up arc-shaped cover 12 is provided with a handle 13 for easy operation of opening and closing.

[0043] In an optional embodiment: the negative pressure dust removal pipe includes a duct 15, a corrugated pipe 16 and an installation pipe 17. The duct 15 is fixedly installed on the input end face of the shaft seal exhaust fan 14. One end of the corrugated pipe 16 is fixedly connected to the other end of the duct 15. One end of the installation pipe 17 is fixedly connected to the other end of the corrugated pipe 16. The other end of the installation pipe 17 is installed on one end of the flip-up arc-shaped cover 12 and passes through it.

[0044] It should be noted that the negative pressure dust removal pipe is composed of a duct 15, a corrugated pipe 16, and an installation pipe 17 connected in sequence. One end of the duct 15 is connected to the air inlet of the shaft seal exhaust fan 14, and the other end is connected to the installation pipe 17 through the corrugated pipe 16 (which can be bent and adjusted in length). The installation pipe 17 passes through the flip-up arc-shaped cover 12 and extends to its inner side, with the pipe opening facing the feed inlet area.

[0045] In this application, the dust escape path is physically blocked by a double-layer sealing component (sealing cover 8 + flip-up arc cover 12), and the directional suction of the negative pressure dust removal component is combined with the dual effect to significantly reduce the dust in operation; the structure of the corrugated pipe 16 allows the flip-up arc cover 12 to adapt to displacement when opening and closing, ensuring the continuous operation of the dust removal pipeline.

[0046] Working principle: During feeding, the operator pulls handle 13 to open the flip-up arc-shaped cover 12, exposing the feed inlet. After adding the sulfur vulcanizing agent and oil-filled material to the mixing tank 1, the flip-up arc-shaped cover 12 is closed, ensuring the sealing strip 19 fits tightly against the mounting plate 10. Simultaneously, the sealing cover 8 presses the first sealing layer 7 under gravity, forming a double seal. The drive motor 3 is started, driving the mixing shaft 4 to rotate. The first mixing blade 5 pushes the material downwards, while the second mixing blade 6 performs transverse shearing and mixing. The shaft seal exhaust fan 14 is started simultaneously. Dust generated inside the feed chamber is drawn to the shaft seal exhaust fan 14 through the mounting pipe 17, corrugated pipe 16, and air duct 15, and finally returns to the mixing chamber through the air outlet. The airflow inside the mixing chamber flows out through the dust filter and then flows back into the feed chamber through the dust filter, thus achieving dust circulation and collection, significantly reducing dust pollution in the external environment. The dust filter installed on the outer wall of the mixing tank 1 is easy to clean or replace.
