Description

Technical Field

[0001] This utility model belongs to the field of waste safety treatment technology, specifically relating to a neutralization reaction mechanism for the safe treatment of tribasic lead sulfate waste. Background Technology

[0002] Lead tribasic sulfate, a commonly used heat stabilizer in the polyvinyl chloride (PVC) industry, generates a large amount of lead-containing waste during its production, application, and recycling of waste plastics. Due to the high toxicity of lead in lead tribasic sulfate, improper handling can easily harm the ecological environment and human health through soil infiltration and water pollution. Currently, neutralization is a common method for treating lead tribasic sulfate waste. This method utilizes acid-base reagents to disrupt the chemical structure of lead tribasic sulfate, converting lead ions into stable, low-toxicity compounds while simultaneously neutralizing potential acidic or alkaline components.

[0003] Currently, the reaction mechanisms used in factories for the neutralization and treatment of tribasic lead sulfate waste typically employ separate longitudinal or transverse stirring methods for neutralization and mixing. However, it is difficult to achieve radial diffusion and thorough mixing solely through longitudinal or transverse stirring. Neutralization with stirring in only one direction results in insufficient reaction, thus requiring extended stirring time and leading to low efficiency in the neutralization and treatment of tribasic lead sulfate waste. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention provides a neutralization reaction mechanism for the safe treatment of tribasic lead sulfate waste, characterized in that it includes a fixed base, a driving assembly, and a stirring assembly. The fixed base has a groove inside. The driving assembly includes a first motor, a first rotating shaft, a half-bevel gear, a first bevel gear, a second bevel gear, a second rotating shaft, and a rotating block. A rotating seat is fixedly connected to the left surface of the rotating block. A reaction chamber is fixedly connected to the inner surface of the rotating seat. A third fixing plate is fixedly connected to the upper surface of the fixed base. A turntable is fixedly connected to the right surface of the third fixing plate. The right surface of the turntable is fixedly connected to the rotating seat.

[0005] Through the above technical solution, the first rotating shaft drives the half-bevel gear to rotate. Under the action of the first and second bevel gears, the second rotating shaft, rotating block, and rotating seat reciprocate, thereby causing the reaction box to reciprocate. This mechanism achieves the synergistic effect of the reciprocating oscillation of the reaction box and internal stirring through the incomplete tooth structure of the half-bevel gear, significantly improving the mixing efficiency.

[0006] The present invention is further configured such that the output end of the first motor is fixedly connected to the first rotating shaft, the side surface of the first rotating shaft is fixedly connected to the half bevel gear, the side surface of the first bevel gear is meshed with the half bevel gear, the side surface of the second bevel gear is meshed with the half bevel gear, the side surface of the second rotating shaft is fixedly connected to the first bevel gear, the side surface of the second rotating shaft is fixedly connected to the second bevel gear, and the inner surface of the groove is rotatably connected to the rotating seat.

[0007] The above technical solution clarifies and refines the connection method of each component of the drive assembly. By utilizing the periodic meshing characteristics of the semi-bevel gear, continuous rotation is transformed into intermittent reciprocating motion, providing a controllable oscillation frequency and angle for the reaction chamber. Furthermore, the slow oscillation during the neutralization of lead waste during the neutralization reaction can prevent splashing.

[0008] The present invention is further configured such that a first fixing plate is fixedly connected to the upper surface of the fixed base, a first bearing is fixedly connected to the left surface of the first fixing plate, and the inner surface of the first bearing is fixedly connected to the second rotating shaft.

[0009] The above technical solution enhances rotational stability by supporting the second rotating shaft with the first fixed plate and the first bearing.

[0010] The present invention is further configured such that a second fixing plate is fixedly connected to the upper surface of the fixed base, a second bearing is fixedly connected to the inner surface of the second fixing plate, and the inner surface of the second bearing is fixedly connected to the second rotating shaft.

[0011] The above technical solution enhances the rotational stability of the second rotating shaft by supporting it with a second fixed plate and a second bearing. At the same time, the first bearing and the second bearing are set up to form a double-support structure, making the rotation smoother.

[0012] The present invention is further configured such that the stirring assembly includes a second motor, a third rotating shaft and a mixing plate, a cover plate is fixedly connected to the side surface of the reaction chamber, the front surface of the cover plate is fixedly connected to the second motor, the output end of the second motor is fixedly connected to the third rotating shaft, the side surface of the third rotating shaft is fixedly connected to the mixing plate, and the side surface of the third rotating shaft is rotatably connected to the cover plate.

[0013] Through the above technical solution, by starting the second motor, the output end of the second motor rotates and drives the third rotating shaft and the mixing plate to stir and mix the materials in the reaction box. The reciprocating oscillation outside the reaction box and the mixing of the internal stirring components form a dual motion, breaking the laminar flow state of traditional stirring, so that the lead waste and the neutralizing agent come into more complete contact. In the process, the efficiency of internal molecular mixing is accelerated, the reaction time is shortened, and thus the reaction efficiency is improved.

[0014] The present invention is further configured such that a protective box is fixedly connected to the upper surface of the fixed base, the side surface of the second rotating shaft is rotatably connected to the first bevel gear, and the half bevel gear, the first bevel gear, and the second bevel gear are all disposed inside the protective box.

[0015] The above technical solution protects the internal components by using a protective box, thereby extending the service life of the internal components.

[0016] The present invention is further configured such that the inside of the reaction chamber is provided with a feed pipe, the inside of the reaction chamber is provided with a liquid inlet pipe, and the inside of the reaction chamber is provided with a discharge pipe.

[0017] The above technical solution involves setting up a feed pipe, a liquid inlet pipe, and a discharge pipe to form a complete feeding, reaction, and discharge process. Neutralizing agent is added into the reaction tank through the liquid inlet pipe.

[0018] The beneficial effects of this utility model are as follows: By setting up components such as a fixed base, groove, first motor, first rotating shaft, half bevel gear, first bevel gear, second bevel gear, second rotating shaft, and rotating block, the reaction chamber can be rotated back and forth during the material stirring process inside the reaction chamber. This mechanism can enhance the mixing effect of the neutralization reaction, form three-dimensional turbulence, and thus improve the uniformity of the reaction. At the same time, it can reduce the reaction dead zone caused by gravity settling. Furthermore, as the reaction chamber rotates back and forth, the internal materials continuously change their trajectory under the alternating action of centrifugal force and inertial force, accelerating the diffusion of ions in the neutralization reaction, thereby shortening the stirring and neutralization time and improving the neutralization reaction efficiency.

A protective box 16 is fixedly connected to the upper surface of the fixed base 1. The side surface of the second rotating shaft 8 is rotatably connected to the first bevel gear 6. The half-bevel gear 5, the first bevel gear 6, and the second bevel gear 7 are all disposed inside the protective box 16. The protective box 16 protects the internal components, thereby extending the internal... To extend the service life of the components, a rotating block 9 has a rotating seat 10 fixedly connected to its left surface, and a reaction chamber 11 fixedly connected to its inner surface. By starting the first motor 3, the first rotating shaft 4 and the half-bevel gear 5 are driven to rotate. Under the action of the first bevel gear 6 and the second bevel gear 7, the second rotating shaft 8, the rotating block 9, and the rotating seat 10 reciprocate, thereby causing the reaction chamber 11 to reciprocate. This mechanism achieves the reciprocating oscillation of the reaction chamber 11 through the incomplete tooth structure of the half-bevel gear 5. Combined with the stirring assembly, it can significantly improve the mixing efficiency. A third fixing plate 17 is fixedly connected to the upper surface of the fixed base 1, and a turntable 18 is fixedly connected to the right surface of the third fixing plate 17. The right surface of the turntable 18 is fixedly connected to the rotating seat 10. The turntable 18 is designed to make the rotating seat 10 and the reaction chamber 11 rotate more flexibly. The inner surface of the groove 2 is rotatably connected to the rotating seat 10. The groove 2 provides a physical support point for the rotating seat 10, ensuring that the reaction chamber 11 remains stable during reciprocating rotation and avoiding shaking and tilting of the equipment due to the shift of the center of gravity.

[0023] A first fixing plate 12 is fixedly connected to the upper surface of the fixed base 1. The first fixing plate 12 is fixedly connected to the first motor 3 and provides support and fixation for the first motor 3. A first bearing 13 is fixedly connected to the left surface of the first fixing plate 12. The inner surface of the first bearing 13 is fixedly connected to the second rotating shaft 8. A second fixing plate 14 is fixedly connected to the upper surface of the fixed base 1. A second bearing 15 is fixedly connected to the inner surface of the second fixing plate 14. The inner surface of the second bearing 15 is fixedly connected to the second rotating shaft 8. The second rotating shaft 8 is supported by the first fixing plate 12, the first bearing 13, the second fixing plate 14, and the second bearing 15, which enhances the rotational stability. At the same time, the first bearing 13 and the second bearing 15 are set to form a double-support structure, making the rotation of the second rotating shaft 8 more stable.

[0024] The stirring assembly includes a second motor 22, a third rotating shaft 23, and a mixing plate 24. A cover plate 21 is fixedly connected to the side surface of the reaction chamber 11. The front surface of the cover plate 21 is fixedly connected to the second motor 22. The output end of the second motor 22 is fixedly connected to the third rotating shaft 23. The side surface of the third rotating shaft 23 is fixedly connected to the mixing plate 24. The side surface of the third rotating shaft 23 is rotatably connected to the cover plate 21. When the second motor 22 is started, the output end of the second motor 22 rotates, driving the third rotating shaft 23 and the mixing plate 24 to rotate and stir the materials in the reaction chamber 11. The reciprocating oscillation outside the reaction chamber 11 and the mixing of the internal stirring assembly form a dual motion, breaking the laminar flow state of traditional stirring, allowing the lead waste to come into more thorough contact with the neutralizing agent, and accelerating the internal molecular mixing process. The reaction chamber 11 is equipped with a feed pipe 19, through which crushed tribasic lead sulfate waste and water are added. A liquid inlet pipe 20 is also provided inside the reaction chamber 11, through which a neutralizing agent is added. A discharge pipe 25 is also provided inside the reaction chamber 11; after the neutralization reaction is complete, the material is discharged through the discharge pipe 25. Solenoid valves are installed in the feed pipe 19, liquid inlet pipe 20, and discharge pipe 25 to facilitate the addition and discharge of materials. An exhaust pipe with a one-way exhaust valve is also provided inside the reaction chamber 11. In this application, the first motor 3, the second motor 22, and the solenoid valves are all electrically connected to the controller.

[0025] The working principle of this utility model is as follows: the crushed tribasic lead sulfate waste is mixed with water to form a slurry of a certain concentration, which is added to the reaction tank 11 through the feed pipe 19. According to the acidity or alkalinity of the waste or the lead salt content, an appropriate amount of neutralizing agent is added through the liquid inlet pipe 20. After the raw materials are added, the first motor 3 and the second motor 22 are started at the same time. The output end of the second motor 22 rotates to drive the third rotating shaft 23 and the mixing plate 24 to rotate and stir the material in the fixed base 1. The output end of the first motor 3 rotates to drive the first rotating shaft 4 and the half bevel gear 5 to rotate. Under the action of the first bevel gear 6 and the second bevel gear 7, the second rotating shaft 8, the rotating block 9, the rotating seat 10, and the reaction tank 11 reciprocate to rotate in the groove 2. The reciprocating rotation of the reaction tank 11 in the groove 2 accelerates the reaction speed of the material in the reaction tank 11 and shortens the neutralization reaction time. After the reaction is completed, the material is discharged from the discharge pipe 25 by opening the solenoid valve on the discharge pipe 25.
