Abstract
The utility model provides a prevent spiral cavity structure of decanter centrifuge inlet pipe fracture, it includes spiral (1), its characterized in that: the feeding cavity (3) is arranged on one side, located at the spiral big end (101), of the cavity of the spiral (1), the feeding cavity (3) is arranged on one side, far away from the spiral big end (101), of the cavity of the spiral (1) and the feeding cavity (2) in an interval mode, and the feeding cavity (3) is communicated with the feeding cavity (2) through a gap (4) between the spiral (1) and the feeding pipe (3). This spiral cavity structural change helical structure moves the returning charge chamber to the main aspects, and the clearance of inlet pipe and spiral enlarges for the material is remaining unlikely to pile up, can follow the returning charge chamber and flow out, and shuts down the collapse on back liquid ring layer, also can play certain washing effect to the returning charge chamber.
Description
Technical Field
The utility model belongs to the technical field of the assembly of spiral shell centrifuge crouches, concretely relates to prevent to crouch cracked spiral cavity structure of spiral shell centrifuge inlet pipe, avoid the remaining material of refluence to block up the inlet pipe and lead to the inlet pipe fracture.
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 that 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 0.005mm and concentration of 2-40%. It can be widely used in chemical industry, light industry, pharmacy, food industry, environmental protection industry, etc.
The feed tube of a horizontal decanter centrifuge is typically mounted on a feed tube support that is mounted on a base frame. As shown in fig. 1, in the existing spiral structure, the material returning cavity is close to the material feeding cavity, and part of the material which does not flow out from the material returning cavity flows to the large end through the gap between the material feeding pipe and the spiral, and long-term deposition causes blockage, so that the material feeding pipe is seriously abraded and even broken.
SUMMERY OF THE UTILITY MODEL
The utility model aims at exactly being to the remaining easy cracked technical defect of inlet pipe that blocks up of above-mentioned material that current return material chamber flows, providing one kind and preventing to crouch the cracked spiral cavity structure of spiral centrifuge inlet pipe, change helical structure, move the return material chamber to the main aspects, the inlet pipe enlarges with the clearance of spiral for the remaining unlikely heap of material, can follow the return material chamber and flow out, and shut down collapsing of back liquid ring layer, also can play certain washing effect to the return material chamber.
Technical scheme
In order to realize above-mentioned technical purpose, the utility model provides a pair of prevent spiral cavity structure of decanter centrifuge inlet pipe fracture, it includes the spiral, its characterized in that: the feeding cavity is arranged on one side, located at the large end of the spiral, of the cavity of the spiral, the feeding cavity is arranged on one side, far away from the large end of the spiral, of the cavity of the spiral and is arranged at intervals with the feeding cavity, and the feeding cavity is communicated with the feeding cavity through a gap between the spiral cavity and the feeding pipe.
Further, the material returning cavity is isolated from the outside by labyrinth sealing.
Further, the material returning cavity is communicated with the spiral liquid phase isolation chamber.
Advantageous effects
The utility model provides a pair of prevent to crouch cracked spiral cavity structure of spiral centrifuge inlet pipe, change helical structure, move the returning charge chamber to the main aspects, the clearance of inlet pipe and spiral enlarges for the remaining unlikely heap of material can flow out from the returning charge chamber, and shuts down collapsing of back liquid ring layer, also can play certain washing effect to the returning charge chamber.

Examples
As shown in the attached figure 2, the spiral cavity structure for preventing the feed pipe of the horizontal decanter centrifuge from being broken comprises a spiral 1 and is characterized in that: the feeding cavity 2 is arranged on one side, located at the spiral big end 101, of the cavity of the spiral 1, the feeding cavity 3 is arranged on one side, far away from the spiral big end 101, of the cavity of the spiral 1 and is arranged at intervals with the feeding cavity 2, and the feeding cavity 3 is communicated with the feeding cavity 2 through a gap 41 between the cavity of the spiral 1 and the feeding pipe 4.
The return chamber 2 is closed off from the outside by means of a labyrinth seal 5.
The return cavity 2 is communicated with the liquid phase isolation chamber 102 of the spiral 1.
The utility model provides a pair of prevent to crouch cracked spiral cavity structure of spiral centrifuge inlet pipe, change helical structure, move the returning charge chamber to the main aspects, the clearance of inlet pipe and spiral enlarges for the remaining unlikely heap of material can flow out from the returning charge chamber, and shuts down collapsing of back liquid ring layer, also can play certain washing effect to the returning charge chamber.
The structure, ratio, size and the like shown in the drawings attached to the present embodiment are only used for matching with the disclosure of the specification, so as to be known and read by those skilled in the art, and are not used to limit the practical limit condition of the present invention, so that the present invention does not have the essential meaning in the technology, and any structure modification, ratio relationship change or size adjustment should still fall within the scope of the present invention without affecting the function and the achievable purpose of the present invention. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle", "clockwise", "counterclockwise", etc. used in the present specification are for the sake of clarity only, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are considered to be the scope of the present invention without substantial changes in the technical content.
