Bag turning centrifugal machine

Abstract

The invention discloses a bag turning centrifugal machine. The bag turning centrifugal machine comprises a rack, a hollow spindle, a drum assembly, a shell body assembly and a rotation power device. A push rod penetrates in the spindle. The tail end of the push rod is connected with a bag turning power device. One end of the push rod penetrates through a through hole formed in a drum bottom to enter an inner cavity of a drum, and the end of the push rod is provided with a material pushing disk. The inner side of the drum wall is provided with a filter bag. One end of the filter bag is arranged at an outer edge opening of the drum. The other end of the filter bag is arranged on the material pushing disk. At least three support rods are evenly distributed on the material pushing disk in the circumferential direction. Material blocking rings are detachably arranged at the other ends of the support rods. The spindle drives the push rod to rotate synchronously through a driving mechanism. The shell body assembly comprises a rear end plate, a cylinder-shaped shell body and a front end cover. A water-seepage-proof and airproof telescopic cover is connected between the cylinder-shaped shell body and the front end cover. The lower end of the telescopic cover is provided with a material discharging hole. The front end cover is provided with a material feeding pipe. The rack is provided with a cover pushing hydraulic cylinder which drives the front end cover to move. The bag turning centrifugal machine is simple in structure, small in covering area, long in service life, and good in sealing performance.

Description

technical field [0001] The invention relates to an inverted bag centrifuge. Background technique [0002] Inverted bag centrifuges generally include a frame, a hollow main shaft and a drum assembly that are arranged on the frame and rotate around a horizontal axis, and a shell assembly that is placed outside the drum assembly. The rotary power device for the rotation of the drum assembly. The main shaft is pierced with a push rod that can slide along the axis of the main shaft. The bag turning power device that moves in the same direction is connected. The drum assembly includes the drum bottom connected to the main shaft and the drum wall arranged on the drum bottom. One end of the push rod enters the drum through the through hole set on the drum bottom. The inner cavity and this end is provided with a push plate; the inner side of the drum wall is provided with a filter bag, one end of the filter bag is set on the outer edge of the drum, the other end of the filter bag is...

Problems solved by technology

[0003] The feeding method of the existing bag-turning centrifuge is as described in the patent 200480006484.5 bag-turning filter centrifuge. The material is fed from the rear of the centrifuge to the drum by passing the feeding pipe through the hollow push rod in the main shaft. , this feeding method not only makes the structure of the centrifuge complicated, but also the seal between the feeding tube and the push rod is easily damaged, which affects the service life of the centrifuge, and it cannot be used for materials that will deteriorate in contact with the air or poisonous materials that will pollute the environment if leaked out. material separation

In addition, since the position of the feeding tube remains unchanged when the push rod is pushed out, it is easy for the material to contaminate the inner cavity of the push rod

[0004] There are also some inverted bag centrifuges that use a feed pipe on the front cover to feed the material. In order to push the filter bag out of the inverted bag centrifuge with this structure, the front cover needs to be opened, which is also not suitable for use with air. Separation of toxic materials that will deteriorate in contact with materials or leak out that will pollute the environment
