Abstract
The utility model provides a spiral shell centrifuge housing seal structure crouches, it includes big end flange (1) and housing (2), its characterized in that: an annular liquid blocking structure is vertically arranged between a liquid phase outlet (101) of the large-end flange (1) and the housing (2), and a bearing seat (4) on the outer side of the large-end flange (1) is provided with a labyrinth seal structure; the technical problem that the bearing is damaged by water inflow of the bearing seat due to a large amount of liquid impact is solved by adding the liquid blocking structure of the liquid phase end housing and the labyrinth sealing structure of the bearing seat. Simultaneously, a labyrinth sealing structure is additionally arranged on the bearing seat, so that liquid leakage is more effectively prevented compared with the original felt sealing structure, and the bearing is protected from being damaged.
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 seal structure 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. When the horizontal screw centrifuge is shut down, because the rotating speed gradually becomes small, a liquid ring layer in the rotary drum can collapse, a large amount of liquid directly impacts the housing, and a labyrinth seal structure is constructed to be overlarge pressure.
SUMMERY OF THE UTILITY MODEL
The utility model aims at that just it is relatively poor to above-mentioned current spiral shell centrifuge housing sealing performance for sleeping in, lead to bearing frame liquid seepage to take place the technical defect that the bearing damaged easily, provide a spiral shell centrifuge housing seal structure for sleeping in, block the labyrinth seal structure of liquid structure and bearing frame through increasing liquid phase end housing, improve the technical problem that liquid strikes in a large number and causes the bearing frame to intake and damage the bearing.
Technical scheme
In order to realize above-mentioned technical purpose, the utility model provides a pair of spiral shell centrifuge housing seal structure crouches, it includes main aspects flange and housing, its characterized in that: an annular liquid blocking structure is vertically arranged between a liquid phase outlet of the large-end flange and the housing, and a labyrinth seal structure is arranged on the bearing seat outside the large-end flange;
the annular liquid blocking knot comprises an L-shaped plate, the lower end of the L-shaped plate is arranged on the outer side face of the liquid phase outlet of the large-end flange, and a flow channel is formed between the L-shaped plate and the outer side face of the liquid phase outlet of the large-end flange.
Further, the labyrinth seal structure is arranged between the bottom of the bearing seat and the large-end flange.
Advantageous effects
The utility model provides a pair of spiral shell centrifuge housing seal structure crouches through the labyrinth seal structure who blocks liquid structure and bearing frame that increases the liquid phase end housing, improves a large amount of liquid and strikes the technological problem that causes the bearing frame to intake and damage the bearing. Simultaneously, a labyrinth sealing structure is additionally arranged on the bearing seat, so that liquid leakage is more effectively prevented compared with the original felt sealing structure, and the bearing is protected from being damaged.
