Description

Technical Field

[0001] This invention relates to the field of coating equipment technology, and in particular to a turbulent wet coating machine. Background Technology

[0002] Coating machines are devices that coat the surface of materials with various solvents. Current coating machines are driven by motors, but the structure of the agitator is simple. When the motor drives the material to mix, the material tends to accumulate in the agitator due to the structure of the agitator, making it difficult for the additives to penetrate the coating and limiting the coating area. At the same time, mechanical wet coating has poor uniformity, long mixing time and low mixing efficiency. Therefore, it is necessary to design a turbulent wet coating machine. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] The present invention provides a turbulent wet coating machine, the advantages of which are: by using a fan to discharge the material in the Y-shaped jet pipe into the coating chamber, and at the same time the liquid pump extracts the solvent in the solvent tank, the turbulent collision coating is carried out in the coating chamber, which improves the uniformity of coating and mixing.

[0023] Please see Figure 1This invention provides an embodiment of a turbulent wet coating machine, comprising a coating component 1, an airflow feeding component 2, a solvent component 3, an additive component 4, and a classification and collection component 5. The coating component 1 consists of a spiral pipe 101 and a coating chamber 102, with the spiral pipe 101 and the coating chamber 102 interconnected. A Y-shaped jet pipe 203 from the airflow feeding component 2 is fitted into a through hole on one side of the coating chamber 102. The coating component 1 allows the solvent and additives to mix along a spiral arc to form a mixed liquid phase. Then, the atomized material and the mixed liquid collide within the coating chamber 102 to generate turbulence, achieving... The mixed liquid penetrates the material, enhancing the coating effect. The airflow feeding assembly 2 consists of a hopper 201, a blower 202, and a Y-shaped jet pipe 203. One end of the Y-shaped jet pipe 203 is connected to the output end of the blower 202, and the other end of the Y-shaped jet pipe 203 is fitted into a through hole at the bottom of the hopper 201. The airflow feeding assembly 2 can accelerate the material discharged from the hopper 201 through the blower 202 and atomize it after passing through the Y-shaped jet pipe 203. The spiral pipe 101 is equipped with the additive pipe 402 of the additive assembly 4, and the spiral pipe 101 and the additive pipe 402 are interconnected. Component 4 consists of an additive chamber 401 and an additive pipe 402. The top end of the additive pipe 402 is fitted into a through hole at the bottom of the additive chamber 401. The additive component 4 creates negative pressure when the solvent flows through the constricted opening of the additive pipe 402, causing the additive to be drawn into the encapsulating component 1 and mixed with the solvent. One end of the spiral pipe 101 is equipped with a jet throat 303 from the solvent component 3, and the spiral pipe 101 and the jet throat 303 are interconnected. The solvent component 3 consists of a solvent chamber 301, a liquid pump 302, and a jet throat 303. The bottom end of the jet throat 303 is connected to the output end of the liquid pump 302. The input end of the liquid pump 302 is connected to the solvent chamber 301. The other end of the spiral pipe 101 is provided with a U-shaped pipe 503 in the classification collection component 5, and the spiral pipe 101 and the U-shaped pipe 503 are connected to each other. The classification collection component 5 consists of a coating body collection chamber 501, a liquid collection chamber 502 and a U-shaped pipe 503. One end of the U-shaped pipe 503 is connected to the coating body collection chamber 501, and the other end of the U-shaped pipe 503 is connected to the liquid collection chamber 502. The classification collection component 5 can accelerate the ejection of the coated material and liquid phase from the coating chamber 102 for classification collection.

[0024] Specifically, in use, the material first falls from the hopper 201, and the blower 202 provides airflow to blow the material into the Y-shaped jet pipe 203. Due to the constriction characteristic of the outlet, the material is accelerated. Furthermore, because the space increases after the material enters the coating chamber 102, the material enters the coating chamber 102 in an atomized manner. Simultaneously, the liquid pump 302 draws solvent from the solvent tank 301, and the solvent is drawn into the jet throat 303 for spraying. The solvent is then sprayed into the spiral pipe 101 of the coating assembly 1. One side of the spiral pipe 101 has a certain... The bulging feature allows the solvent to better conform to the spiral pipe 101 and reduces the impact of the solvent on the pipe wall. The interface between the additive pipe 402 of the additive assembly 4 and the spiral pipe 101 is in the form of a T-junction, and the outer wall of the spiral pipe 101 first contracts and then expands along the direction of solvent flow. Therefore, the solvent will be accelerated at this point, thereby creating a negative pressure at the pipe connection. This negative pressure draws the additive from the additive chamber 401 into the additive pipe 402, and then from the additive pipe 402 into the spiral pipe 101 to mix with the solvent. The junction of chamber 102 has a tapering feature, and due to the increased area of ​​the coating chamber 102, the mixed solvent and additives enter the coating chamber 102 with certain atomization characteristics. Subsequently, the atomized material and atomized liquid, due to their perpendicular spray directions and high collision velocity, and large atomization area, can exchange momentum, resulting in a turbulent flow. This turbulent flow increases the probability of the material generating rotational motion, thereby increasing the contact time and contact area between the material and the liquid. This allows the liquid to fully coat the material surface, thus improving the coating machine's performance. The uniformity of the coating and mixing, after the interaction between the two, leaves behind the coating body and the liquid. Due to the high velocity of the liquid jet above the coating chamber 102, and under the influence of gravity, the two leave the coating chamber 102 at a certain speed. Then, they enter the U-shaped pipe 503 in the graded collection component 5 through a spiral pipe 101. Due to the difference in density between the two, the denser coating body falls at the position of the coating body collection chamber 501, while the less dense liquid is thrown into the liquid collection chamber 502, realizing the function of graded collection and improving the collection efficiency.
