Description

Spiral conveying device capable of separating solid from liquid and production line

Technical Field

The utility model relates to a conveying equipment technical field, concretely relates to spiral delivery mechanism and production line that can solid-liquid separation.

Background

The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

The solid-liquid separation mode mainly comprises the following steps:

1. solid-liquid separation is processed by a physical filtration interception mode, the physical filtration mode is divided into a pressure reduction filtration mode and a pressure filtration mode, and a pressure filter and a filter sieve are common in industrial application.

2. Separating by the specific gravity difference of solid and liquid phases;

(1) and centrifugal separation: a method for separating substances having different specific gravities by centrifugal force. Because the centrifugal machine and other processing equipment can generate quite high angular velocity, the centrifugal force is far greater than the gravity, suspended matters in the solution are easy to precipitate and separate out, and because the centrifugal forces applied to the substances with different specific gravities are different, the settling velocity is different, and the substances with different specific gravities can be separated.

(2) Gravity settling: the solid-liquid separation equipment utilizes the density difference between particles and fluid to make them produce relative movement and settle, i.e. gravity settling, under the action of gravitational field. Gravity settling is the simplest method of separating dust particles from a fluid. Only when the particles are large and the flow velocity is small, the gravity settling effect is obvious;

3. the separation is carried out by utilizing the chemical properties of certain substances, such as solid at low temperature and liquid at high temperature.

The screw conveyer is a machine which utilizes a motor to drive a screw to rotate and push materials to realize the conveying purpose. The liquid conveying device can convey liquid horizontally, obliquely or vertically, and has the advantages of simple structure, small cross section area, good sealing property, convenience in operation, easiness in maintenance, convenience in closed transportation and the like. The spiral conveying device is divided into a shaft spiral conveying device and a shaftless spiral conveying device in the conveying form, and is divided into a U-shaped spiral conveying device and a tubular spiral conveyor in the appearance. The shaftless screw conveyor is suitable for dry powder materials and small particle materials without viscosity (such as liquid mud, fly ash, lime, grains and the like), and the shaftless screw conveyor is suitable for materials with viscosity and easy winding of a conveyor. The working principle of the spiral conveying device (such as sludge, biomass, garbage and the like) is that a rotating spiral blade pushes and conveys materials, and the force which prevents the materials from rotating together with the spiral conveying device blade is the self weight of the materials and the frictional resistance of a shell of the spiral conveying device to the materials. The spiral conveying device conveys spiral blades welded on a shaft in a rotating mode, and the surface types of the blades are solid surface types, belt surface types, blade surface types and the like according to different conveyed materials. The screw shaft of the screw conveying device is provided with a thrust bearing at the terminal of the material moving direction so as to provide axial counterforce to the screw along with the material, and when the screw shaft is longer, a middle hanging bearing is added.

The inventors have found that the solid-liquid separation device and the screw conveyor are two separate operating units. If the solid-liquid separation is realized and the separated solid is conveyed away, a set of separate solid-liquid separation device and a conveying device are respectively added. Thus, the occupied area is increased, the investment is increased, and the operation units are increased.
