Description

Technical Field

[0001] This utility model belongs to the field of enameled wire enamel preparation technology, specifically relating to a raw material dispersion and addition device for enameled wire enamel preparation. Background Technology

[0002] Enamelled wire varnish is a coating that creates a good insulating layer between conductors in a winding. It is mainly used on the outer layer of bare copper wire, alloy wire, and glass fiber-coated wire of various diameters to improve and stabilize the performance of enamelled wire.

[0003] The preparation process of enameled wire enamel mainly involves sequentially placing raw materials such as ultrafine zinc oxide, nano-sized silica powder, fumed silica, titanium dioxide, and molybdenum titanium powder into a stirring container and stirring to obtain a mixture. Then, bisphenol A type epoxy resin, polyamide resin, isocyanate, hydroxyl resin, and 1 / 3 of the reactive diluent are added and stirred continuously to obtain another mixture. This mixture is then added to a reaction vessel, and butyl rubber, polytetrafluoroethylene, polyacrylate, dimethyl ethanolamine, polyimide, and 2 / 3 of the reactive diluent are added sequentially. The reaction vessel is heated and stirred continuously to obtain enameled wire enamel.

[0004] Therefore, it can be seen that mixing various raw materials is the main process and an essential step in the preparation of enameled wire enamel. In addition, different raw materials need to be added continuously for mixing during the preparation process. Existing mixing devices for enameled wire enamel preparation directly add raw materials into the mixing tank, which can easily cause the raw materials to accumulate locally in the mixing tank and form lumps, which can affect the mixing efficiency and quality.

[0005] Therefore, in order to solve the above problems, it is necessary to develop a raw material dispersion and addition device for enameled wire coating preparation. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a raw material dispersion and addition device for enameled wire coating preparation, which can disperse and add raw materials, avoid raw material accumulation and agglomeration, and improve stirring efficiency and stirring quality.

[0007] The purpose of this utility model is achieved as follows: a raw material dispersion and addition device for preparing enameled wire paint, including a frame, a mixing tank is provided on the frame, a stirring device and a feeding device are respectively provided on the mixing tank, and a discharge device is also provided at the bottom of the mixing tank;

[0008] The stirring device includes a stirring motor located at the bottom of the stirring tank, a stirring shaft located inside the stirring tank, and several stirring rods located on the side wall of the stirring shaft. The stirring motor drives the stirring shaft and stirring rods to rotate inside the stirring tank for stirring.

[0009] The feeding device includes a main feeding pipe located at the top of the mixing tank. The main feeding pipe is rotatably connected to the mixing tank via a rotating bearing. A rotating motor is connected to the upper part of the main feeding pipe via a transmission device. The bottom end of the main feeding pipe extends into the mixing tank and is connected to a distribution box. At least one distribution port is provided at the bottom end of the distribution box. A distribution feeding pipe is connected to the distribution port. The bottom end of the distribution feeding pipe extends obliquely towards the inner wall of the mixing tank. The rotating motor drives the main feeding pipe to rotate. During the rotation of the main feeding pipe, the distribution box and the distribution feeding pipe rotate inside the mixing tank to add raw materials into the mixing tank.

[0010] Furthermore, the discharge device includes a discharge port located at the bottom of the mixing tank, a discharge pipe located at the discharge port, and a control valve located on the discharge pipe.

[0011] Furthermore, the output shaft of the stirring motor is connected to a rotating shaft, the top end of which passes through the stirring tank via a rotating bearing and extends into the stirring tank to connect to the stirring shaft.

[0012] Furthermore, the stirring motor and the rotating motor are both reversible motors.

[0013] Furthermore, the transmission device is implemented using a gear transmission assembly or a belt and pulley transmission assembly.

[0014] Furthermore, an arc-shaped protrusion is provided at the middle position of the bottom surface inside the material distribution box, and the material distribution port is located next to the arc-shaped protrusion.

[0015] The beneficial effects of this utility model are as follows: By setting a rotatable main feeding pipe at the top of the mixing tank and driving the main feeding pipe to rotate by a rotating motor, the main feeding pipe drives the distribution box and the distribution feeding pipe to rotate inside the mixing tank during rotation, and adds raw materials into the mixing tank. This achieves the rotary distribution of raw materials, which evenly disperses the raw materials into the mixing tank, preventing the raw materials from accumulating and clumping inside the mixing tank, and improving the mixing efficiency and mixing quality. In summary, this utility model has the advantages of evenly dispersing the addition of raw materials and improving the mixing efficiency and mixing quality. Attached Figure Description

[0022] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 , Figure 2 As shown, a raw material dispersion and addition device for preparing enameled wire paint includes a frame 1, a mixing tank 2 is provided on the frame 1, a stirring device 3 and a feeding device 4 are respectively provided on the mixing tank 2, and a discharge device 5 is also provided at the bottom of the mixing tank 2.

[0024] The stirring device 3 includes a stirring motor 3a disposed at the bottom of the stirring tank 2, a stirring shaft 3b disposed inside the stirring tank 2, and a plurality of stirring rods 3c disposed on the side wall of the stirring shaft 3b. The stirring motor 3a drives the stirring shaft 3b and the stirring rods 3c to rotate inside the stirring tank 2 for stirring. Specifically, the output shaft of the stirring motor 3a is connected to a rotating shaft, the top end of which passes through the stirring tank 2 through a rotating bearing and extends into the stirring tank 2 to connect with the stirring shaft 3b. Preferably, the stirring motor 3a can be a reversible motor.

[0025] The feeding device 4 includes a main feeding pipe 4a located at the top of the mixing tank 2. The main feeding pipe 4a is rotatably connected to the mixing tank 2 via a rotating bearing. A rotating motor 4c is connected to the upper part of the main feeding pipe 4a via a transmission device 4b. The bottom end of the main feeding pipe 4a extends into the mixing tank 2 and is connected to a distribution box 4d. At least one distribution port 4e is provided at the bottom end of the distribution box 4d. A distribution feeding pipe 4f is connected to the distribution port 4e. The bottom end of the distribution feeding pipe 4f extends inclined towards the inner wall of the mixing tank 2. The rotating motor 4c drives the main feeding pipe 4a to rotate. During the rotation, the main feeding pipe 4a drives the distribution box 4d and the distribution feeding pipe 4f to rotate inside the mixing tank 2, adding raw materials into the mixing tank 2.

[0026] Preferably, the rotating motor 4c can be a reversible motor; preferably, the transmission device 4b is implemented by a gear transmission assembly or a belt and pulley transmission assembly; an arc-shaped protrusion 4g is provided at the middle position of the bottom surface inside the material distribution box 4d, and the material distribution port 4e is located next to the arc-shaped protrusion 4g. By setting the arc-shaped protrusion 4g, the raw materials can be prevented from accumulating in the material distribution box 4d, so that the raw materials can fall quickly along the arc surface of the arc-shaped protrusion 4g to the material distribution port 4e, accelerating the discharge of the raw materials from the material distribution box 4d.

[0027] When adding raw materials, the raw materials enter the distribution box 4d from the main feeding pipe 4a, enter the distribution pipe 4f through the distribution port 4e, and are discharged into the mixing tank 2 through the distribution pipe 4f. At the same time, the rotating motor 4c is started to drive the main feeding pipe 4a to rotate, which in turn drives the distribution pipe 4f to rotate and move, so as to add raw materials at different positions inside the mixing tank 2, realize the rotational distribution of raw materials, and evenly disperse the raw materials into the mixing tank 2, so as to avoid the raw materials from accumulating and clumping inside the mixing tank 2.

[0028] The discharge device 5 includes a discharge port 5a located at the bottom of the mixing tank 2, a discharge pipe 5b located at the discharge port 5a, and a control valve 5c located on the discharge pipe 5b. The material after mixing can be discharged through the discharge port 5a and the discharge pipe 5b.

[0029] It should be noted that the technical features of the stirring motor 3a, the rotating motor 4c and their specific connection structure, as well as the control valve 5c described in this application, are all prior art and common knowledge to those skilled in the art. They can be implemented through various feasible methods, and no other special requirements are made in this application. It is sufficient that they can achieve the functions described in this application, so no specific limitations are made here.
