Problems solved by technology

When using a scraper to scrape materials, for some materials with light specific gravity, when the scraper is screwed into the material rotating at a low speed, the material under the liquid blocking plate will splash when it is scraped by the blade, and when the drum rotates, it will Fly to the top of the liquid blocking plate, and discharge the drum with the liquid, causing the loss of material
When the existing centrifuge is unloading, the lifting drive mechanism is used to drive the scraper shaft up and down, and the rotary drive mechanism drives the scraper shaft to rotate, which consumes a lot of energy and costs high
In addition, when the existing centrifuge is distributing the material, the material is unevenly distributed on the drum, which increases the burden of unloading

Embodiment Construction

[0018] refer to figure 1 , figure 2 , image 3 , Figure 4 , the present invention proposes an automatic discharge vertical centrifuge, comprising a casing 1, a main shaft 2, a drum 3 sleeved on the main shaft 2, a machine cover 4 fixed on the top of the casing 1, a controller, a scraper device, the feed box 62 and the second driving device 61 arranged inside the rotating drum 3, wherein:

[0019] Such as figure 1 As shown, the bottom of the drum 3 is provided with a discharge port, and the discharge port is provided with a split-type movable door 31, and screen holes are distributed on the movable door 31, and the movable door 31 is connected with the controller. During the rotation of the centrifuge, the residual liquid is discharged out of the drum 3 through the discharge port, and the residual liquid may take away part of the solids. A movable door 31 with a sieve hole is arranged at the discharge port to remove the residual liquid. The solid mixed in the residual li...

Abstract

The invention puts forward an automatic-unloading vertical centrifuge. A scraping device comprises a scraper shaft, a scraper base, a scraper, a driving gear, a driven gear, and a first drive device, wherein a controller is connected to the first drive device, the first drive device is connected to the driving gear to drive rotation of the driving gear, the driven gear is engaged with the driving gear, one end of the scraper shaft passes through the driven gear and is connected to the driven gear by threads, the other end of the scraper shaft passes through a machine cover and is stretched into a drum and connected with the scraper base, and the scraper is installed on the scraper base; and a first air duct is disposed inside the scraper shaft, a second air duct is disposed inside the scraper base, the first air duct is communicated with the second air duct, blowing nozzles which blow wind to the inner wall of the drum are disposed on two sides of the scraper on the scraper base, and the blowing nozzles are communicated with the second air duct. The automatic-unloading vertical centrifuge provided by the invention can realize lifting, descending and rotation of the scraper shaft by the drive device, the driving gear and the driven gear.

Description

technical field [0001] The invention relates to the technical field of centrifuges, in particular to an automatic unloading vertical centrifuge. Background technique [0002] A centrifuge is a device that uses the principle of centrifugal separation to separate the suspended material into solid and liquid. A centrifuge has a cylinder, called a bowl, that rotates at high speed about its own axis, usually driven by an electric motor. After the suspension (or emulsion) is added to the drum, it is quickly driven to rotate at the same speed as the drum, and the components are separated under the action of centrifugal force and discharged separately. Generally, the higher the drum speed, the better the separation. [0003] According to different solid phase unloading methods, centrifuges can be divided into gravity unloading, manual upper unloading, manual lower unloading, centrifugal unloading, scraper unloading, vacuum suction and screw unloading. The scraper discharge centri...
