Description

Technical Field

[0001] The utility model belongs to the technical field of water pollution prevention and control, and particularly relates to a new separation device for treating water pollution. Background Art

[0002] The essence of sewage treatment is to separate and transform pollutants in water. Most of the final products obtained by transformation need to be separated and removed, so separation is a very important part of the sewage treatment process, which will directly affect the effect and cost of sewage treatment. Strengthening the separation process is of great significance to the improvement of the level of sewage treatment technology.

[0003] The sewage separation process often uses external magnetic powder to enhance the flocculation effect, improve the sedimentation efficiency, and thus improve the sewage treatment effect; in addition, high shear machines must be used in the sewage separation process. Almost all domestic manufacturers' high shear machines use metal blades to separate magnetic powder and sewage. The main component of magnetic powder is ferroferric oxide, which has a relatively high hardness.

[0004] In an environment where mud and magnetic powder are mixed, there are many agglomerates and large particles. If a traditional high-speed shearing machine is used, the blade edge of the high-speed shearing machine will be worn by the agglomerates and large particles during the high-speed operation of the metal blade. The metal blade is very damaged and the machine must be stopped frequently to replace the blade. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a new separation device for treating water pollution.

[0006] The non-metallic dispersion disk for treating water pollution has a certain thickness, so that the non-metallic dispersion disk is not easily damaged when hit; an axis-penetrating hole is provided in the center of the non-metallic dispersion disk, and a clamping groove is formed on the inner wall of the axis-penetrating hole, the axis-penetrating hole is used to pass the dispersion disk on the axis, and the clamping groove is used to clamp the non-metallic dispersion disk at a set position on the axis; a plurality of channels are evenly formed in the solid part between the axis-penetrating hole and the outer edge of the non-metallic dispersion disk, and the opened channels mainly play the role of accelerating the impact of materials, which is conducive to breaking up mud and dirt lumps and large particles; the outer edge wall of the non-metallic dispersion disk is a combination of a cylindrical side wall and a plane side wall, and a plane side wall is between each two adjacent cylindrical side walls, and the plane side wall forms a section.

[0007] Preferably, the non-metallic dispersion disk is made of tetrafluoroethylene.

[0008] Preferably, a blade is fixedly provided at the bottom of the non-metallic dispersion disk, the fixed end of the blade is in conformity with the shape of the non-metallic dispersion disk, and a circular hole is also provided at the fixed end of the blade for passing through the shaft; the circumference of the fixed end of the blade is smaller than the circumference of the non-metallic dispersion disk; and a plurality of cutting edges pointing downward at 90 degrees are provided at intervals on the outer edge of the blade.

[0009] As a preference, the cutting edge is triangular or trapezoidal as a whole; when the cutting edge is trapezoidal, the side with a longer waist is arranged downward, and the side with a shorter waist is arranged toward the non-metallic dispersion disk.

[0011] Preferably, a corresponding blade is provided on the bottom of each non-metallic dispersion disk, and the blade is fixedly connected to the bottom of the non-metallic dispersion disk.

[0012] The beneficial effects of the utility model are as follows: the utility model designs a non-metallic dispersion disk with a certain thickness, which is mainly used for stirring and mixing a mixture of mud and dirt agglomerates, large particles and magnetic powder. The plane of the non-metallic dispersion disk can collide with the mixed mud and dirt agglomerates and large particles during stirring, so that the large particles inside the mixture collide with each other, thereby achieving the effect of refining the mud and dirt mixture; the non-metallic dispersion disk is provided with a cutting surface and a channel, and the opened channel mainly plays the role of accelerating the impact of materials, which is conducive to breaking up the mud and dirt agglomerates and large particles; a blade can be further provided under the non-metallic dispersion disk, and the edge of the blade has a 90-degree cutting edge (not very sharp). At a certain rotation speed, the blade is wear-resistant and can also play a certain shearing effect. In addition, the large-angle blade also increases the blade strength, improves the blade durability, and makes the blade unnecessary to be replaced frequently. BRIEF DESCRIPTION OF THE DRAWINGS
