Abstract

The utility model provides an anti-residue feeding device, which includes a hopper, and is characterized in that the top of the hopper is provided with a blowing ring pipe with a plurality of spray holes on it, and the blowing ring pipe is connected with a gas source through a pipeline, which can be conveniently The pressure gas sprayed out through the blowing ring pipe will blow off the material attached to the hopper wall, effectively preventing the material from remaining on the hopper wall. It has good anti-residue and anti-adhesion effects, and the cleaning effect is obvious, which fundamentally solves the time-consuming and labor-intensive problems caused by manual cleaning in the prior art.

Description

An anti-residue blanking device

technical field

The utility model relates to a blanking device, in particular to an anti-residue blanking device, which belongs to the technical field of mechanical design and manufacture.

Background technique

At present, many chemical companies use large centrifuges to separate solid-liquid materials. The working principle is that the motor drives the drum to rotate at a high speed to generate centrifugal force. After the material enters the drum, it is filtered under the action of centrifugal force and filter cloth, and finally reaches solid purpose of liquid separation. The moisture content of the material separated by centrifuge dehydration is 15-18wt%, which belongs to high water content and high viscosity material, so it is easy to adhere and remain on the wall of the scraper hopper during the subsequent material transportation process, affecting the normal operation. The material cannot even be transported, so that the centrifuge needs to be stopped for manual cleaning every hour of work on average, which not only restricts the continuous production of the centrifuge, but also increases the labor intensity of the workers. Therefore it is necessary to improve the prior art.

Contents of the invention

In order to solve the problem that the scraper hopper of the existing centrifuge is very easy to adhere to the wall surface of the water-containing material, which makes feeding difficult and restricts the continuous production of the centrifuge, the utility model provides an anti-residue feeding device.

The utility model is completed through the following technical proposals: an anti-residue feeding device, including a hopper, characterized in that the top of the hopper is provided with a blowing ring pipe with a plurality of nozzle holes, and the blowing ring pipe passes through the pipeline and the air source Connected so that when the material adheres to the wall of the hopper, the pressure gas sprayed out through the blowing ring will blow off the material attached to the wall of the hopper, effectively preventing the material from remaining on the wall of the hopper.

The blowing ring pipe is set as a circular ring pipe or a rectangular ring pipe adapted to the shape of the top of the hopper, and circular nozzle holes or strip nozzle holes are arranged at intervals at the bottom of the circular ring pipe or rectangular ring pipe, so as to Spray pressure gas to the wall of the hopper in time to prevent material from adhering to the wall.

The utility model is completed through the following technical scheme: adopting the above scheme, the pressure gas ejected from the blowing ring pipe can conveniently blow off the material attached to the hopper wall, effectively preventing the material from remaining on the hopper wall, and the device does not need The internal structure of the equipment is greatly changed, and only a simple installation can play a good anti-residue and anti-adhesion effect, and the cleaning effect is obvious, which fundamentally solves the time-consuming and labor-intensive problems caused by manual cleaning in the prior art.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

The anti-residue blanking device provided by the utility model includes a hopper 1, wherein the top of the hopper 1 is provided with a blowing ring pipe 2 with a plurality of spray holes 6 on it, and the blowing ring pipe 2 is connected to the gas source through a pipeline 3 , the air source is a compressed air machine, and the outer end 5 of the pipeline 3 is connected to the compressed air machine; the injection ring pipe 2 is set as a rectangular ring pipe suitable for the shape of the top of the hopper 1, and is spaced at the bottom of the rectangular ring pipe. Four spray holes 6 are set, and these four spray holes 6 are strip spray holes, which are respectively arranged on the left side, the front side, and the rear side of the bottom of the rectangular ring pipe, so as to spray the left side wall, the front side wall, and the rear side of the hopper 1. The side wall is sprayed with pressure air, as shown in Figure 1, which can effectively prevent the material from remaining on the hopper wall.
