Description

Technical Field

[0001] This utility model relates to the field of powder mixing technology, and in particular to a mixing tank. Background Technology

[0002] Mixed tanks are widely used industrial equipment in various fields such as coatings, pharmaceuticals, building materials, chemicals, pigments, resins, food, and scientific research. Their core function is to perform processes such as stirring, mixing, blending, and homogenizing materials. The working mechanism of a mixed tank can be summarized by three basic principles: shearing, diffusion, and convection. The rotational motion of the stirring device generates shear force, causing relative movement of substances and achieving a mixing effect. Simultaneously, the rotation of the stirring device also promotes diffusion, increases the interfacial area between different components, and accelerates the mixing process. Furthermore, the substances within the mixed tank undergo convection under the rotation of the stirring device, further driving the mixing reaction.

[0003] In practical applications, materials are typically fed into mixing tanks via pipelines. During this process, the materials often pile up directly. Due to the tight packing, the agitator needs to apply greater force and spend more time to break up the dense structure between the materials and achieve uniform mixing. This not only increases energy consumption and prolongs the mixing cycle but also negatively impacts production efficiency.

[0004] Materials with insufficient bulk density are difficult to mix evenly during stirring, easily leading to problems such as excessively high or low concentrations in certain areas. This not only adversely affects product quality but may also cause a series of problems in subsequent production processes. Utility Model Content

[0005] The main objective of this invention is to provide a mixing tank that can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A mixing tank includes a tank body, mounting bases, a sealing cover, a support frame, and a drive motor. Multiple mounting bases are installed on the lower side wall of the tank body. The sealing cover is installed on the tank body. The drive motor is installed on the sealing cover via the support frame. The output end of the drive motor is connected to a stirring rod, and the stirring rod is used to achieve the stirring operation of materials inside the tank body.

[0008] The side wall of the tank is connected to a vent pipe, and an exhaust valve is installed at the upper and lower ends of the vent pipe, and the exhaust operation of the tank is realized through the exhaust valve.

[0009] The upper edge of the sealing cover is equipped with a connecting pipe, and the upper end of the connecting pipe is equipped with a storage pipe. A manual valve is provided at the connection between the connecting pipe and the storage pipe, and a pump body is connected to the outer end of the manual valve. The upper end of the storage pipe is connected to a feed inlet through a gate valve. The material enters through the feed inlet, gate valve and connecting pipe, and the pump body introduces fresh air and additives into the connecting pipe, blowing the material to loosen it and allow it to enter the tank, thereby improving the mixing efficiency.

[0010] In a further alternative, the vent pipe is designed in a "U" shape, inserted into the tank and fixed with a nut, with a sealing ring at the connection point. The exhaust valve is installed on the vent pipe through a connecting flange, and the exhaust valve allows the exhaust of air from inside the tank. The vent pipe opening and the middle section of the pipe are equipped with a filter membrane.

[0011] In a further alternative, the sealing cap is fixed to the tank body with bolts, the support frame is located at the upper center of the sealing cap and is fixed to the sealing cap with bolts, the drive motor is a servo motor, the servo motor is fixed to the support frame with bolts, and the output end of the servo motor passes through the support frame and the sealing cap and is connected to the stirring rod.

[0012] In a further alternative, the connecting pipe and the storage pipe are designed as a single unit, and the lower end of the connecting pipe is connected to the sealing cap via a connecting flange. The storage pipe, the feed inlet, and the gate valve are connected via a connecting flange. An electric push rod is installed on the side wall of the gate valve, and the opening and closing of the storage pipe and the feed inlet are achieved through the electric push rod.

[0013] In a further alternative, the upper opening of the feed inlet is designed as a flared mouth, the manual valve and the connecting pipe are connected by threads, and a sealing ring is provided at the connection. The manual valve is a ball valve, which is used to open and close the pipeline and control the flow rate.

[0014] As a further alternative, an instrument, namely a flow meter, is installed on the pipeline between the manual valve and the pump body.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] A pump blows fresh air and added materials, causing the materials to scatter and disperse, accelerating their entry into the tank and thus improving mixing efficiency. A drive motor rotates the stirring rod, ensuring uniform mixing of the materials within the tank. Simultaneously, an exhaust system regulates the pressure inside the tank to prevent the formation of air bubbles or uneven mixing during the process. A flow meter accurately measures the material flow rate, ensuring the accuracy of the material ratio and thus guaranteeing the quality of the final product.

[0017] The vent valve can regulate the pressure inside the tank, preventing equipment damage or material leakage due to excessive pressure during the mixing process, and ensuring the safety of the mixing process.

[0018] The entire system is highly automated. It controls the opening and closing of gate valves via electric actuators and adjusts manual valves to achieve rapid material delivery and precise control, reducing manual operation and improving production efficiency. Attached Figure Description

[0029] The connecting pipe 8 and the storage pipe 9 are integrated into one unit. The lower end of the connecting pipe 8 is connected to the sealing cap 5 via a connecting flange. The storage pipe 9, the feed inlet 11, and the gate valve 10 are connected via a connecting flange. An electric actuator is installed on the side wall of the gate valve 10, which opens and closes the storage pipe 9 and the feed inlet 11 to control the inflow and outflow of materials.

[0030] The upper opening of the feed inlet 11 is designed in the shape of a flared mouth to facilitate the smooth entry of materials.
