Description

Device for preventing blanking blockage of centrifugal machine

Technical Field

The utility model belongs to the technical field of the sugar alcohol preparation equipment, in particular to device that prevention centrifuge unloading was blockked up.

Background

At present, the centrifugal machine is widely applied to the industries of chemical industry, food, pharmacy and the like, and the working principle of the centrifugal machine is to accelerate the separation of different materials to be separated through centrifugal force. Centrifuges are generally classified as either filter centrifuges or decanter centrifuges, depending on their application in different industries. The filtering centrifuge is mainly characterized in that liquid phase in solid-liquid mixed liquid is thrown out of the rotary drum in an accelerating way through centrifugal force generated by a centrifugal rotary drum running at a high speed and the interception effect of a screen, and solid phase is remained in the rotary drum to achieve the effect of solid-liquid separation; the main principle of the decanter centrifuge is to accelerate the sedimentation velocity of components (solid phase or liquid phase) with different specific gravities in the mixed liquid by the strong centrifugal force generated by the high-speed rotation of the rotor, and separate the substances with different sedimentation coefficients and buoyancy densities in the sample. In the crystallization process in sugar mills, the crystallized massecuite is often subjected to rapid separation using a filter centrifuge. The crystals and the mother liquor in the massecuite are diffused to the rotary drum wall by the centrifugal force of high-speed operation, the solid crystals can be intercepted by the screen at the rotary drum wall, and the liquid mother liquor can permeate the screen, so that the aim of solid-liquid separation is fulfilled. After separation, the crystals intercepted on the screen wall need to be scraped into a material receiving bin at the bottom of the centrifuge through a scraper, and usually, the bottom of the material receiving bin is connected with a conveying auger so as to convey the separated solids to the next process. However, in the actual operation of the sugar refinery, the scraping is finished at one time, and the centrifuged material is still in a wet state, so that the material is very easy to block the wall of the discharging bin or the joint of the conveying auger, the conveying auger transmission resistance is increased, certain damage to the equipment is caused, the bin at the bottom of the centrifuge needs to be knocked manually after the material is blocked, the workload of workers is increased, the service efficiency of the equipment is low, the continuity of the production of the equipment is influenced, and the service life of the equipment is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a device that prevention centrifuge unloading was blockked up is provided, avoids the material to pile up at the adhesion of centrifuge's silo wall, prevents that the material from blockking up centrifuge unloading passageway.

The utility model discloses a realize like this, provide a device that prevention centrifuge unloading blockked up, including installing pivot and a plurality of blade in feed bin under the bottom, a plurality of blade settings are in the pivot, and the pivot is transversely erect on the inner wall of the left and right sides of feed bin under the bottom, and the pivot is by setting up the motor drive outside feed bin under the bottom, and feed bin sets up in centrifuge's lower part under the bottom, and the lower part in feed bin sets up the screw conveyer of transported substance material under the bottom.

Further, still include the air hammer, the air hammer sets up on the outer wall of feed bin under the bottom.

Furthermore, the rotating shaft and the blades are made of stainless steel materials.

Further, a scraper is provided within the centrifuge.

Compared with the prior art, the utility model discloses a device of prevention centrifuge unloading jam installs the pivot in the middle of the feed bin under the centrifuge bottom, installs the blade in the pivot, and the material after the centrifugation is when getting into feed bin under the bottom, breaks up the effect through the blade of pivot, makes the material get into the screw conveyer who sets up in its bottom smoothly, can not pile up in centrifuge bottom feed bin. In addition still install the air hammer outside the feed bin, through the air hammer vibration, make the material that adheres at the feed bin inner wall can all retrieve to screw conveyer in, avoid the material to pile up at the adhesion of feed bin wall, prevent that the material from blockking up centrifuge unloading passageway, greatly improve centrifuge's availability factor.

Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, the preferred embodiment of the device for preventing blanking clogging of a centrifuge of the present invention comprises a shaft 5 and a blade 6 installed in the bottom lower bin 2 of the centrifuge 1, and an air hammer 7 installed on the outer wall of the bottom lower bin 2. A scraper 3 is provided in the centrifuge 1. The scraper 3 scrapes off the material adhering to the inner wall of the centrifuge 1. And a screw conveyor 4 for conveying materials is arranged at the lower part of the bottom blanking bin 2.

The rotating shaft 5 is transversely erected on the inner walls of the left side and the right side of the bottom blanking bin 2. The rotating shaft 5 is driven by a motor (not shown in the figure) arranged outside the bottom blanking bin 2. The rotating shaft 5 rotates to drive the blades 6 to rotate, materials stacked at the bottom of the blanking bin 2 are separated, stacking of the materials at the position is avoided, the materials smoothly enter the spiral conveyor 4 at the bottom of the blanking bin, and production continuity is guaranteed.

The outer wall of the bottom discharging bin 2 is impacted and knocked by the air hammer 7, so that the wall of the bottom discharging bin 2 vibrates, and materials adhered to the inner wall of the bottom discharging bin 2 fall off to enter the spiral conveyor 4.

The material of pivot 5 and blade 6 is stainless steel material, prevents to be corroded the rusty contaminated material.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
