Description

A fast filter separation device

technical field

The invention relates to a fast filtering and separating device.

Background technique

At present, filter devices are widely used in the process of solid-liquid separation. Although a certain separation effect has been achieved, there are still many disadvantages. For example, when the suspension is subjected to solid-liquid separation, due to the high viscosity and small fineness of the solid in the suspension system, it is easy to accumulate on the filter cloth, forming a thicker filter cake and reducing the filtration speed, especially in the case of pressurization When filtering under the filter cloth, the solids are compressed on the filter cloth to form a dense filter cake layer, which seriously restricts the filtration speed and eventually leads to difficulty in filtration.

Contents of the invention

In view of the above problems, the present invention proposes a rapid filtration and separation device, which can greatly increase the filtration speed, improve the production efficiency and prolong the service life of the filter cloth.

The present invention mainly adopts the following technical solutions: a rapid filtration and separation device, including a cylinder body, a filter cloth is provided at the lower end of the cylinder body, and a material return port is provided on the upper part of the filter cloth; the cylinder body communicates with the upper part of the hydrocyclone through a liquid lifting pipe , the bottom of the hydrocyclone is connected to the material return port through a return pipe; the top of the hydrocyclone is provided with a liquid outlet I.

During operation, the solid-liquid mixed suspension enters the cylinder from the feed inlet, and compressed air enters the cylinder from the gas inlet. Under the action of compressed air, a part of the mixed suspension is filtered through the filter cloth inside the cylinder to achieve solid-liquid separation. Settling on the filter cloth, the liquid is discharged from the liquid outlet II at the lower part of the cylinder through the filter cloth; at the same time, another part of the mixed suspension enters the hydrocyclone through the liquid riser, and the clear liquid with a lower density is discharged from the The liquid outlet I at the top of the hydrocyclone is discharged, and the suspension that has not been fully separated is returned to the cylinder through the return pipe through the return port for the next filtration and separation process. After multiple filtration and separation processes, all the solids settle on the filter cloth, and the liquid is discharged from the cylinder, realizing efficient and thorough separation of solids and liquids.

In addition, the solid-liquid mixed suspension described in the above process can also be the suspension obtained directly after the reaction in the barrel.

Further, a jacket is provided on the outside of the cylinder body, through which hot fluid or hot air can be introduced to heat the cylinder body to realize the drying of the solid.

In summary, the present invention adopts the combination of filter cloth filtration and hydrocyclone, which has the following beneficial effects:

1. Greatly improved the filtering speed and shortened the filtering time;

2. Reduce the filter load of the filter cloth and prolong the service life of the filter cloth;

3. Reduce the amount of compressed air, reduce the energy consumption and cost of filtration and separation;

4. It can integrate reaction, filtration separation and drying into one, which is more convenient to use.

detailed description

A rapid filtration and separation device, comprising a cylinder body 1, a filter cloth 2 is provided at the inner lower end of the cylinder body 1, and a material return port 3 is provided at the upper part of the filter cloth 2; , the bottom of the hydrocyclone 4 is connected to the return port 3 through the return pipe 6; the top of the hydrocyclone 4 is provided with a liquid outlet I8.

During operation, the solid-liquid mixed suspension enters the cylinder 1 from the feed port 9, and the compressed air enters the cylinder 1 from the gas inlet 10. Under the action of the compressed air, a part of the mixed suspension is filtered through the filter cloth 2 inside the cylinder 1 Realize solid-liquid separation, the solid settles on the filter cloth 2, and the liquid is discharged from the liquid outlet II11 at the bottom of the cylinder 1 through the filter cloth 2; at the same time, another part of the mixed suspension enters the hydrocyclone through the liquid riser 5 In 4, the clear liquid with a lower density is discharged from the liquid outlet I8 at the top of the hydrocyclone 4, and the suspension that has not been fully separated is returned to the cylinder 1 through the return pipe 6 through the return port 3 for the next step. Filtration separation process. After multiple filtration and separation processes, all the solids settle on the filter cloth, and the liquid is discharged from the cylinder 1, realizing efficient and thorough separation of solids and liquids.

A jacket 7 is provided on the outside of the cylinder body 1, through which hot fluid or hot air can be introduced to heat the cylinder body 1 to realize the drying of the solid.
