Description

Technical Field

[0001] This utility model belongs to the technical field of mixing equipment, specifically relating to a mixing and stirring device for recovering M in the synthesis of rubber accelerator CBS. Background Technology

[0002] In the recovery of alkali powder during the synthesis of CBS rubber accelerator, the materials and alkali powder are typically fed into a stirred tank for reaction. After the reaction, impurities are filtered out, and the filtrate is then neutralized in a neutralization tank. The neutralized product is a viscous substance, which is then centrifuged to remove excess water. However, alkali powder is prone to moisture absorption and clumping during long-term storage, affecting its reaction with the materials in the stirred tank and reducing reaction efficiency, thus hindering production. Therefore, a mixing and stirring device for alkali powder recovery in CBS rubber accelerator synthesis is needed to solve the aforementioned technical problems. Utility Model Content

[0003] To address the aforementioned deficiencies in existing technologies, this utility model provides a mixing and stirring device for M recovery in the synthesis of rubber accelerator CBS, comprising a stirring vessel with an inlet, an exhaust pipe, and an outlet pipe; a filter cylinder is installed inside the stirring vessel, with an inlet pipe at the top of the filter cylinder; a rotating rod is installed inside the filter cylinder, and a crushing blade is mounted on the rotating rod; a connecting rod is fixedly connected to the upper end of the rotating rod; the connecting rod extends into the inlet pipe and is fixedly connected to the inner wall of the inlet pipe via a fixing rod; the lower end of the connecting rod is lower than the lower end of the inlet pipe, and the diameter of the connecting rod is smaller than the diameter of the inlet pipe; the rotating rod... The upper end is tapered, narrower at the top and wider at the bottom. The upper end of the feed pipe extends from inside the mixing vessel and is rotatably connected to the mixing vessel via a bearing. A feed hopper is provided at the top of the feed pipe. A bevel gear one is fixed on the feed pipe outside the mixing vessel. The bevel gear one meshes with a bevel gear two, which is connected to a motor. A support rod is connected to the bottom of the filter cylinder. The lower end of the support rod is connected to the inner wall of the reaction vessel. The filter cylinder is rotatably connected to the feed pipe via a bearing. This design allows the alkali powder to enter the filter cylinder through the feed hopper without affecting the rotation of the rotating rod, allowing the crushing blade to disperse the alkali powder inside the filter cylinder.

[0004] A stirring rod is connected to the feed pipe inside the mixing vessel. The stirring rod includes a horizontal rod, one end of which is fixedly connected to the outer wall of the feed pipe, and the other end of which is fixedly connected to a vertical rod.

[0005] Preferably, two vertical rods are provided, and brush bristles one and two brush bristles are respectively connected to the two vertical rods. Brush bristles one contacts the inner wall of the mixing vessel, and brush bristles two contacts the outer wall of the filter cartridge. The mixing process can clean the inner wall of the mixing vessel and the outer wall of the filter cartridge, avoiding material adhesion and filter cartridge clogging.

[0006] Preferably, the upper part of the feed pipe located outside the mixing vessel is rotatably connected to a support platform via a bearing. The support platform is connected to the mixing vessel via a vertical telescopic rod. The feed hopper and the bevel gear are both located on the feed pipe above the support platform. The motor is fixed on the support platform, and the support rod is a telescopic sleeve rod. This arrangement allows for synchronous up-and-down movement of the stirring rod and filter cartridge during the stirring process, achieving diverse stirring directions, further improving the stirring range and effect, and enabling the alkali powder in the filter cartridge to react more fully and quickly with the materials.

[0007] Preferably, the vertical telescopic rod is an electric push rod or a hydraulic cylinder, the fixed end of the vertical telescopic rod is fixed to the mixing vessel by a bracket, and the telescopic end of the vertical telescopic rod is vertically downward and fixedly connected to the support platform.

[0008] Preferably, the mixing vessel is equipped with a filter screen, and the side wall of the mixing vessel corresponding to the filter screen is provided with an openable cleaning port.

[0009] Preferably, the crushing blades are spirally distributed on the rotating rod and cooperate with the filter cartridge. The motor is a forward and reverse motor, which can drive the rotating rod to rotate in both directions. The spiral crushing blades can transport the material in the filter cartridge up and down, improving the filtration effect and efficiency.

[0010] This invention also includes other components that enable the mixing and stirring device for M recovery in the synthesis of rubber accelerator CBS to function normally, such as the control components for the motor, the electric push rod, and the hydraulic cylinder, all of which are conventional technologies in the field. Furthermore, devices or components not specified in this invention, such as forward and reverse motors, electric push rods, and hydraulic cylinders, all employ conventional technologies and equipment in the field.

[0011] Working principle: The material and alkali powder enter the mixing tank. The alkali powder enters the filter cylinder directly through the feed hopper. Under the action of the fixed rod, the motor can drive the feed pipe and the rotating rod to rotate synchronously. During the rotation, the crushing blade breaks up the alkali powder in the filter cylinder. After being filtered by the filter cylinder, the broken alkali powder enters the mixing tank to mix with the material. The stirring rod stirs the material and alkali powder, which improves the mixing effect and mixing efficiency.

[0012] The beneficial effects of this utility model are: reasonable structure, simple to use, and can crush and disperse the material entering the filter cartridge while stirring the material in the mixing tank, thereby improving mixing efficiency and mixing effect. Attached Figure Description
