Hoisting tool for drum and screw of horizontal spiral decanter centrifuge

Abstract

The invention relates to a hoisting tool for a rotary drum and a screw rod of a horizontal spiral settling centrifugal machine. The hoisting tool comprises a tool body and is characterized in that the tool body comprises a rotary drum hoisting tool body and a screw rod hoisting tool body; two rows of upper and lower steel wire rope hoisting holes are formed in the rotary drum hoisting tool body in parallel; the screw rod hoisting tool body is fixedly connected with one end of the rotary drum hoisting tool body to form an integrated body through bolts; the screw rod hoisting tool body is in an L shape, and the upper end of the screw rod hoisting tool body is shaped like a square connecting plate which is provided with bolt passing holes; a connecting disc is fixedly connected with the hook-shaped end surface of the lower side of the screw rod hoisting tool body, and is fixedly connected with a hoisting flange through screws. The hoisting tool for the rotary drum and the screw rod of the horizontal spiral settling centrifugal machine has the beneficial effects that scratch between the screw rod and the rotary drum is avoided during the production process and the maintaining process of the centrifugal machine, the quality of the centrifugal machine is ensured, the detaching and hoisting efficiency is improved, and a guarantee is provided for a production and maintenance cycle of the centrifugal machine.

Description

technical field [0001] The invention belongs to a hoisting tool, in particular to a hoisting tool for a drum and a screw rod of a horizontal spiral sedimentation centrifuge. Background technique [0002] Horizontal spiral decanter centrifuge is a machine that uses centrifugal force to separate liquid and solid particles. The separation work is carried out in the drum of the centrifuge, and the material particles are thrown to the inner wall of the drum by centrifugal force, and then pushed out of the drum by the screw. LW650, LW720, LW1100 horizontal screw decanter centrifuges are centrifuges used to separate PVC slurry, LW650-D centrifuge is used to separate soybean protein slurry. [0003] Horizontal spiral decanter centrifuge occupies an important position in the production of chemical products such as PVC, soybean protein and dimethyl terephthalate production. Most of the centrifuges run continuously for 24 hours, and the failure of the centrifuge will cause the entire...

Problems solved by technology

When lifting, use a wire rope to hang in the middle of the drum. Because the lifting center is difficult to control, it is very dangerous, especially when the screw is pulled out from the drum, it is time-consuming and labor-intensive. The screw often scratches the inner wall of the drum, resulting in overall maintenance time. very long
