Description

Technical Field

[0001] The invention relates to the technical field of automatic material taking, and in particular to an upper cover material taking mechanism. Background Art

[0002] Solid-liquid separation of silver nitrate is an important step in the preparation or purification of silver nitrate, which aims to effectively separate the silver nitrate dissolved in the solution from the undissolved solid impurities or reaction by-products. According to the type, particle size and density of solid impurities in the silver nitrate solution, a suitable solid-liquid separation method is selected, such as filtration, centrifugation or sedimentation. The separation device is also an indispensable part of the process. The existing solid-liquid separators basically meet the needs, but there are still certain shortcomings; the existing solid-liquid separators mainly rely on manual shoveling when discharging, which has high labor intensity for employees, low discharging efficiency and high labor costs, and is prone to material spillage. Manual shoveling is prone to direct contact with the material and may be corroded by silver nitrate. Therefore, it is necessary to design an upper cover material taking mechanism. Summary of the invention

[0006] As a preferred technical solution, the driven wheel is sleeved on one end of the lifting tube, and a threaded fixing piece is connected to the threaded groove on the inner wall of one end of the lifting tube. A stopper is fixedly connected to the bottom of the threaded fixing piece. Both the threaded fixing piece and the stopper are rotatably connected to the suction tube. A locking piece is sleeved on the suction tube, and the locking piece is fixedly connected to the support plate.

[0011] Compared with the prior art, the beneficial effects of this solution are:

[0012] The servo motor is started to drive the output end of the reducer to rotate, and the reducer drives the transmission rod to rotate, and then drives the first transmission gear and the second transmission gear on the transmission rod to rotate. The rotation of the first transmission gear drives the lifting tube to move up and down, and then the material-retrieving motor is started to drive the transmission wheel to rotate. The transmission wheel drives the driven wheel to rotate through the transmission belt. The rotation of the driven wheel drives the lifting tube to rotate, and then drives the material-retrieving device at the bottom to rotate. The lifting height is adjusted by the servo motor and the reducer, and then the material-retrieving device is driven by the material-retrieving motor to rotate the solid-liquid separator. After material is retrieved, the suction pipe is used to suck the material into the vacuum suction machine silo to complete the discharging. No manual shoveling is required, which reduces the working intensity of workers, avoids corrosion damage caused by direct contact with materials, and avoids material spillage. At the same time, it effectively improves the discharging efficiency and reduces labor costs. BRIEF DESCRIPTION OF THE DRAWINGS
