Description
Technical Field
The utility model belongs to the technical field of the spiral shell centrifuge assembly crouches, concretely relates to spiral shell centrifuge housing explosion-proof subassembly crouches.
Background
The selection of the horizontal screw centrifuge is a device for performing solid-liquid separation on suspension feed liquid by utilizing the centrifugal separation principle. The working principle is as follows: the rotary drum and the screw rotate at a high speed in the same direction at a certain differential speed, materials are continuously introduced into the conveying screw inner cylinder through the feeding pipe, enter the rotary drum after being accelerated, and heavy solid-phase substances are deposited on the wall of the rotary drum to form a slag layer under the action of a centrifugal force field. The conveying screw continuously pushes the deposited solid-phase substances to the conical end of the rotary drum and discharges the solid-phase substances out of the machine through the slag discharge port. The lighter liquid phase forms an inner layer liquid ring, continuously overflows from the rotary drum through an overflow port at the large end of the rotary drum, and is discharged out of the machine through a liquid discharge port. The horizontal screw centrifuge can continuously feed, separate, wash and discharge materials under full speed operation. The device has the characteristics of compact structure, continuous operation, stable operation, strong adaptability, high production capacity, convenient maintenance and the like. Is suitable for separating suspension containing solid phase with particle size of more than 0.003mm and concentration of 2-40%. It can be widely used in chemical industry, light industry, pharmacy, food industry, environmental protection industry, etc. During the operation of the horizontal spiral centrifuge, the housing is filled with methane, and a gap exists between the housing and the rotating spiral shaft neck, so that safety accidents can be caused once the methane leaks.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a housing inner cover shell is full of the easy defect that leads to the incident to take place of leaking of marsh gas when just to above-mentioned current spiral shell centrifuge that crouches moves, provides an explosion-proof subassembly of spiral shell centrifuge housing crouches, and housing and high-speed rotatory spiral both ends dynamic seal department adopt and fill nitrogen gas protection architecture, guarantee the security and the stability of spiral shell centrifuge that crouches when the high-speed operation.
Technical scheme
In order to realize above-mentioned technical purpose, the utility model provides a pair of spiral shell centrifuge housing explosion-proof assembly crouches, it includes rotatory spiral and housing, its characterized in that: the end covers are installed at two ends of the rotary screw and connected with the housing, the end covers are fixedly installed on the housing, a first sealing ring is arranged between the end covers and the housing, a sealing ring is arranged between the end covers and the rotary screw, a nitrogen connector is installed on the end covers, and a channel is formed in the end covers to enable the nitrogen connector to be communicated with the rotary screw so that nitrogen gas provided by the nitrogen connector can be used for nitrogen filling protection during high-speed operation of a horizontal screw centrifuge.
Advantageous effects
The utility model provides a pair of spiral shell centrifuge housing explosion-proof subassembly crouches, housing and high-speed rotatory spiral both ends movive seal department adopt and fill nitrogen gas protection architecture, guarantee the security and the stability of spiral shell centrifuge when high-speed operation crouches.
