Micro-positive pressure air-tight seal type bag turning type automatic centrifugal machine capable of achieving uniform feeding

Abstract

The invention relates to a micro-positive pressure air-tight seal type bag turning type automatic centrifugal machine capable of achieving uniform feeding. The centrifugal machine comprises a feeding pipe, a fixed guiding mechanism used for bearing the feeding pipe and guiding the feeding pipe, a driving mechanism used for driving the feeding pipe to move back and forth in the limiting direction of the fixed guiding mechanism, and a hose connected with a feeding inlet of the feeding pipe. The fixed guiding mechanism is fixed to the centrifugal machine. The feeding pipe penetrates through the fixed guiding mechanism to enter the centrifugal machine, and a discharging outlet of the feeding pipe is inserted into a centrifugal cavity of the centrifugal machine. According to the centrifugal machine, uniform material distribution can be achieved in the length direction of a rotor, a uniform filter cake layer can be better formed, and the uniform washing effect can also be achieved. The centrifugal machine further pressurizes the interior of the centrifugal machine and the gap between the contact surfaces of the driving shaft part and the centrifugal machine shell through a first pressurizing part and a second pressurizing part so that the oxygen content in the centrifugal machine can be reduced, the sealing performance of the centrifugal machine is enhanced, and the running safety of the centrifugal machine is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of centrifuge feeding, and in particular relates to a slightly positive pressure air-tight bag-turning automatic centrifuge for uniform feeding. Background technique [0002] Separation machinery is mainly composed of centrifuges, filters, etc. With the development of economy and technology, separation machinery has become more and more widely used, and its automation requirements have become higher and higher, and the centrifuge feeding device has also been greatly developed. [0003] The feeding device of the traditional centrifuge mainly consists of the following methods: 1. fixed feeding tube type; 2. conical distributor driven by a motor. The former has a single feeding point, which is easy to form an uneven filter cake layer, the centrifugal motor balance is damaged, and the equipment vibrates greatly, which is unfavorable to the use, maintenance, and safety of the equipment; the conical distributor so...

AI Technical Summary

Problems solved by technology

The increase of the length L of the rotor further increases the difficulty of evenly distributing the material, so there is an urgent need for a feeding device that can evenly distribute the material or wash in the direction of the entire length of the rotor.
