Description

Technical Field

[0001] The utility model belongs to the field of solid-liquid separators, and in particular relates to a spiral solid-liquid separator. Background Art

[0002] A solid-liquid separator is a device used to separate solids and liquids. In the chemical industry, the problem of solid-liquid separation is often involved. However, in the prior art, a filter screen is generally used for filtration, which may cause blockage and cannot screen materials of different particle sizes.

[0003] During the solid-liquid separation process, the problem of discontinuous solid-liquid separation in the mixed liquid may also occur. Utility Model Content

[0004] The purpose of the utility model is to overcome technical deficiencies and provide a spiral solid-liquid separator, which can realize solid-liquid separation and at the same time transport solids. Through the device, the solid-liquid separation of the mixed liquid can be carried out continuously, and the screening of materials with different particle sizes can be realized.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A spiral solid-liquid separator comprises a separator, wherein a mixed liquid feed port is arranged above one end of the separator, a clear liquid outlet is arranged below the separator corresponding to the mixed liquid feed, a solid discharge port is arranged below the other end, a spiral tube is arranged inside the separator, and one end of the spiral tube is connected to an external motor.

[0007] Furthermore, the portion above the clear liquid outlet connected to the separator is funnel-shaped, connected to a vacuum tube, and can be vacuumed. A mesh-like grid is provided at the position connected to the separator, and a filter cloth is placed on the grid for vacuum filtration of the liquid.

[0008] The motor in the utility model is variable frequency, and the screw speed can be adjusted according to the material characteristics and material working conditions.

[0009] In the utility model, the mixed liquid feed port and the solid discharge port are respectively located at two ends of the spiral tube, and the positions of the inlet and outlet can be interchanged according to the production environment space.

[0010] The mesh-like grid of the spiral tube in the utility model plays a supporting role, on which a filter cloth or filter screen that can be fixed and easily disassembled is placed, and below which a vacuum pipe is connected. The filter cloth or filter screen can be selected with different particle sizes as needed, that is, materials with different particle sizes can be screened.

[0011] Working principle:

[0012] The utility model uses vacuum filtration to separate solid and liquid, and uses spiral rotation to achieve continuous solid-liquid separation. The mixed liquid enters the spiral tube at the feed port, and when passing through the filter cloth of the spiral tube, the clear liquid passes through the filter cloth and enters the vacuum pipeline, and the solid that does not pass through the filter cloth is squeezed out by the spiral tube at the other port, thereby achieving continuous solid-liquid separation.

[0013] The beneficial effects of the utility model are:

[0014] The utility model realizes better separation of solid and liquid by arranging vacuum filtration, and realizes continuous separation of solid and liquid by arranging the spiral tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to enable those skilled in the art to better understand the present invention and to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the present invention is further described in detail below in conjunction with embodiments.

[0018] Example 1

[0019] A spiral solid-liquid separator comprises a separator 1, wherein a mixed liquid feed port 2 is arranged above one end of the separator 1, a clear liquid outlet 3 is arranged below the separator corresponding to the mixed liquid feed, a solid discharge port 4 is arranged below the other end, a spiral tube 5 is arranged inside the separator 1, and one end of the spiral tube is connected to a motor 6 arranged outside the separator; a part connected to the separator 1 above the clear liquid outlet 3 is funnel-shaped and connected to a vacuum tube, and a filter cloth mesh grille 7 is arranged at the position connected to the separator.

[0020] Working process of spiral solid-liquid separator:

[0021] The mixed liquid enters the spiral tube of the separator at the feed inlet. When passing through the filter cloth under the spiral tube, under the action of vacuum filtration, the clear liquid passes through the filter cloth and enters the vacuum pipe. The solid that does not pass through the filter cloth is squeezed out at the other end of the spiral tube, thereby realizing continuous separation of solid and liquid.

[0022] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
