Description

A leak-proof device for the discharge gate of a mixer Technical Field

[0001] This invention relates to the field of mixing device technology, and in particular to a leak-proof device for the discharge gate of a mixer. Background Technology

[0002] The main function of the mixer is to promote uniform mixing of materials. It mixes and stirs the materials in the tank by rotating blades to ensure that the materials in the tank reach the optimal mixing state, thereby improving the efficiency and quality of fermentation. In addition, the mixer can also make substances with different specific gravities and viscosities than water evenly mixed in water. Because a large amount of dust and particulate matter are generated during the mixing process, a discharge gate is needed to discharge the mixed materials to achieve the fluidity of the materials during the mixing process and to control the discharge speed and flow rate of concrete.

[0003] Chinese patent CN112265148A discloses an industrial IoT cement slurry mixing device, including a load-bearing platform. A pivot hole is formed on the front of the load-bearing platform, and a pivot is rotatably connected to the inner wall of the pivot hole. A connecting support is rotatably connected to the surface of the pivot. Hydraulic cylinders are rotatably connected to both the front and back of the load-bearing platform. A discharge plate is provided on the upper surface of the load-bearing platform, and a first support plate and a second support plate are fixedly connected to the upper surface of the discharge plate. A placement hole is formed on the side of the first support plate, and the inner wall of the placement hole is fixedly connected to... The device includes a support sleeve, and a mounting hole is provided on the side of the second support plate. A mixing drum is rotatably connected to the inner wall of the mounting hole. An inlet and outlet pipe is provided at the end of the mixing drum away from the first support plate. This industrial IoT cement slurry mixing device uses a rotating shaft, hydraulic cylinder, unloading plate, mixing drum, and scraper to extend the hydraulic cylinder and lift the unloading plate, causing the mixing drum to tilt to the right to pour cement slurry. At the same time, the mixing drum rotates while the scraper remains stationary, scraping off the cement slurry adhering to the inner wall of the mixing drum. This solves the problem of cement slurry being difficult to pour out, thereby achieving a clean unloading effect.

[0004] The above-mentioned scraper can effectively prevent cement slurry from sticking to the inner wall of the mixing drum, thereby achieving a uniform mixing effect. However, the above-mentioned solution cannot seal the connection of the anti-leakage device, which will also lead to material leakage at the connection. It cannot better prevent material leakage at the connection and reduces the sealing performance of the anti-leakage device of the mixer discharge gate. Summary of the Invention
