Description
Technical Field
The invention belongs to the technical field of horizontal screw centrifuge assembly, and particularly relates to an explosion-proof component of a housing of a horizontal screw centrifuge.
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.
Disclosure of Invention
The invention aims to overcome the defect that the inner cover shell of the encloser is filled with methane and is easy to leak out to cause safety accidents when the existing horizontal screw centrifuge operates, and provides an explosion-proof assembly for the encloser of the horizontal screw centrifuge.
Technical scheme
In order to achieve the technical purpose, the invention provides an explosion-proof component of a housing of a horizontal screw centrifuge, which comprises a rotary screw and a housing, and is 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
According to the explosion-proof assembly for the housing of the horizontal screw centrifuge, the housing and the movable sealing parts at two ends of the high-speed rotating screw are in a nitrogen-filled protection structure, so that the safety and the stability of the horizontal screw centrifuge during high-speed operation are ensured.
