Description

Technical Field

[0001] The invention relates to the technical field of homogenizing emulsification devices, in particular to a gapless shearing ceramic pulverizing, dispersing and homogenizing emulsification device. Background Art

[0002] At present, ordinary stainless steel gap homogenizers mainly use the narrow gap between the stator and rotor (the gap between the stator and rotor is between 0.2-1mm) to form a comprehensive effect of strong, reciprocating hydraulic shear, friction, centrifugal extrusion, and liquid collision in the wet material, and circulate the above working process in the container to finally obtain the product. The dispersed particle size produced by this homogenizer can only significantly improve the particle size of the medium within the obtainable particle size range (the diameter of the dispersed particles produced by this homogenizer is currently only between 2-5μm). In addition, too long a dispersion time can only increase the temperature of the medium and has no significant effect on the refinement of the particle size.

[0003] The Chinese patented ceramic ultrafine homogenizer, with authorization announcement number CN204194055U, utilizes multiple ceramic stator rings and centrifugal rotors to shear the material multiple times, improving shear fineness. The staggered placement of the conveying slots between each pair of ceramic stator rings and each pair of centrifugal rotors prevents the material from being sheared and refined through the narrow gap between the centrifugal rotor's ceramic blades and the ceramic stator rings, instead allowing it to be conveyed directly through the conveying slots of the ceramic stator rings. This ensures that the material remains finely conveyed within the narrow gap. However, as the material passes through the conveying slots of each centrifugal rotor and ceramic stator ring, most of the material passes directly through the conveying slots without being sheared and refined, directly affecting work efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a gapless shearing ceramic pulverizing, dispersing, homogenizing and emulsifying device to solve the problem of low working efficiency when conventional ceramic pulverizing, dispersing, homogenizing and emulsifying devices are used.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0029] like Figure 1 As shown, this embodiment discloses a gapless shearing ceramic pulverizing, dispersing, homogenizing and emulsifying device, which includes a homogenizing shaft, a stator housing 5 sleeved on one end of the homogenizing shaft, a stator ring 4 installed in the stator housing 5, and a rotor cutter head installed at one end of the homogenizing shaft and located in the stator ring 4;

[0030] The homogenizing shaft includes a forward rotor shaft 1 and a counter-rotating rotor shaft 2 sleeved on the outside of the forward rotor shaft 1 via a bearing spacer 3. In this embodiment, the forward rotor shaft 1 is longer than the counter-rotating rotor shaft 2. A suction and stirring disc 1d is installed at the lower end of the forward rotor shaft 1 and extends out of the stator housing 5.

[0031] A forward cutter disc 1b is mounted on the forward rotor shaft 1 and located inside the stator ring 4, and a forward cutter disc upper cover plate 1a and a forward cutter disc lower cover plate 1c are mounted on the forward rotor shaft 1 and located axially above and below the forward cutter disc 1b; the suction and slurry stirring disc 1d is located below the forward cutter disc lower cover plate 1c; an inverse cutter disc 2b is mounted on the reverse rotor shaft 1 and located inside the stator ring 4, and an inverse cutter disc upper cover plate 2a and a inverse cutter disc lower cover plate 2c are mounted on the forward rotor shaft 1 and located axially above and below the inverse cutter disc 2b; the forward cutter disc 1b mounted on the forward rotor shaft 1 and the inverse cutter disc 2b mounted on the reverse rotor shaft 2 rotate clockwise and counterclockwise at high speed, respectively, and the centrifugal rotor blades 6 mounted on the forward cutter disc 1b and the inverse cutter disc 2b are thrown out and fit tightly against the inner surface of the stator;

[0032] In this embodiment, the stator ring 4 is made of a special carbon-gold-silicon composite ceramic material. Compared with ordinary metal materials, this material has high hardness, good wear resistance, and is non-toxic and pollution-free.

[0033] In this embodiment, the stator housing 5 is a hollow cylindrical structure with a feed port and a discharge port provided on the top and bottom thereof. The stator ring 4 is fixed in the stator housing 5 , and the stator upper cover plate 4a and the stator lower cover plate 4b on the stator ring 4 are fixed on the feed port and the discharge port of the stator housing 5 .

[0034] like Figure 2 As shown, the outer peripheral sides of the forward cutter disc 1b and the reverse cutter disc 2b are provided with reserved card slots and cutter disc feed troughs 7 for installing centrifugal rotor blades 6, and a stator shearing hole 4b is provided on the outer peripheral wall of the stator ring 4; the outer peripheral wall of the stator housing 5 is provided with a stator housing discharge hole 5a connected to the stator shearing hole 4b; in this embodiment, the centrifugal rotor blades 6 are also made of a carbon-gold-silicon special composite ceramic material. Since the centrifugal rotor blades 6 and the inner wall of the stator ring 4 are in high-speed rotation friction, if ordinary metal materials are used, wear will be generated due to the high-speed friction, resulting in heavy metal pollution to the material. At the same time, the use of the carbon-gold-silicon special composite ceramic reduces the temperature rise rate during high-speed rotation friction;

[0035] In this embodiment, the centrifugal rotor blades 6 are installed in the slots of the forward cutter disc 1b and the reverse cutter disc 2b, and the centrifugal rotor blades 6 are positioned in the slots of the forward cutter disc 1b and the reverse cutter disc 2b by their respective upper and lower cover plates. When the forward cutter disc 1b and the reverse cutter disc 2b rotate at high speed, the centrifugal rotor blades 6 are thrown out under the action of centrifugal force and fit tightly with the inner surface of the stator ring 4. The centrifugal rotor blades 6 and the stator shear holes 4b on the stator ring 4 form a "scissor mouth", thereby shearing and crushing the material.

[0036] like Figure 2 As shown, in this embodiment, the reserved card slots for installing the centrifugal rotor blades 6 and the cutter disc feed trough 7 on the forward rotor cutter disc 1b are distributed one after another, and at the same time, the forward rotor cutter disc upper cover plate 1a and the forward rotor cutter disc lower cover plate 1c are also provided with material conveying troughs that pass through the cutter disc feed trough 7. The material conveying troughs of the forward rotor cutter disc upper cover plate 1a and the forward rotor cutter disc lower cover plate 1c correspond to the cutter disc feed trough 7 on the forward rotor cutter disc 1b, forming a material flow channel to facilitate the passage of material, wherein the forward rotor cutter disc upper cover plate 1a and the forward rotor cutter disc lower cover plate 1c only serve as a limit for the centrifugal rotor blades 6; wherein the forward rotor cutter disc 1b has the same structure as the forward rotor cutter disc 1b.

[0037] like Figure 3 As shown, a reverse upper cover plate feeding trough 2aa is provided on the reverse cutter disc upper cover plate 2a.

[0038] like Figure 4 As shown, a stator discharge trough 4aa is provided on the stator upper cover plate 4a, and a feed trough is provided on the stator lower cover plate 4b. The positions of the discharge trough 4aa and the feed trough correspond to the cutter disc feed trough 7 on the forward cutter disc 1b and the reverse cutter disc 2b, so as to form a material flow channel.

[0039] In this embodiment, the suction paddle disc 1d is mounted on the forward rotor shaft 1. During high-speed rotation, it draws in material and delivers it through the feed trough on the stator lower cover plate 4c into the cutter disc feed troughs 7 of the forward and reverse cutter discs 1b and 2b. As the material passes through the stator lower cover plate 4c and the forward cutter disc lower cover plate 1c, it is sheared and crushed at the material delivery notch. As the material passes through the forward cutter disc upper cover plate 1a and the reverse cutter disc lower cover plate 2c, it is sheared and crushed at the material delivery notch. As the material passes through the reverse cutter disc lower cover plate 2c and the stator upper cover plate 4a, it is sheared and crushed at the material delivery notch.

[0040] In this embodiment, the clockwise rotation of the clockwise cutter disc 1b and the counterclockwise rotation of the counterclockwise cutter disc 2b create a comprehensive effect of intense, reciprocating hydraulic shear, friction, centrifugal extrusion, and fluid collision. This device increases material processing capacity within the same operating time, significantly improving product quality and work efficiency.
