Description

Technical Field

[0001] This utility model relates to the field of mixer technology, specifically to a continuous masterbatch mixing device. Background Technology

[0002] During the granulation process of masterbatch production, many factors can negatively impact the uniformity of the masterbatch. For example, unstable extruder temperature can lead to inconsistent melting states of raw materials during processing; fluctuating voltage may affect the operating parameters of the equipment, thereby altering processing conditions; insufficient or excessive preheating time can cause differences in the initial processing state of the raw materials; and poor batch uniformity of raw materials can also directly result in low uniformity of the produced masterbatch.

[0003] Traditional masterbatch mixing involves mixing different batches of masterbatch products together. However, this method has significant drawbacks. Traditional horizontal or vertical mixers are prone to jamming at the shaft connection, causing the material to rub against each other and become contaminated with lubricating oil and other impurities. The loading and unloading processes consume a lot of manual time; mixing almost two tons at a time reaches the motor's limit. The equipment is expensive, and continuous mixing is impossible, severely impacting masterbatch mixing efficiency and consequently hindering the overall progress and quality of masterbatch production.

[0004] Therefore, it is of great significance to provide a continuous masterbatch mixing device to solve the problems existing in the prior art. Utility Model Content

[0005] In view of this, the purpose of this application is to provide an uninterrupted masterbatch mixing device to solve the problem.

[0006] A continuous masterbatch mixing device, characterized in that it comprises: A frame, on the top of which are respectively installed mixing tank one, mixing tank two, mixing tank three and mixing tank four; Material three-way valve one is installed between the top of the first mixing tank and the second mixing tank; Material three-way valve two is installed between the top of mixing tank three and mixing tank four; Material three-way valve three is installed between the top ends of material three-way valve one and material three-way valve two, and material three-way valve one, material three-way valve two and material three-way valve three have the same specifications; The bottom end of the material three-way valve is provided with two discharge ports, and a valve stem is rotatably connected inside. The valve stem is fixedly connected to a valve plate. A fixing frame is installed on one side of the material three-way valve and is hinged to a cylinder; A rotating rod is fixedly connected to the end of the valve stem and protrudes from the surface of the material three-way valve. The end of the rotating rod is hinged to the telescopic end of the cylinder. Pneumatic valves are respectively installed at the bottom of the first, second, third and fourth mixing tanks, and the bottom of the pneumatic valves are connected to connecting pipes. The feed pipe has its inlet end connected to the outlet end of the two connected pipes in pairs; Static mixing blades are installed inside the two feed pipes respectively.

[0007] Preferably, a motor is installed at the top of each of the three mixing tanks: mixing tank one, mixing tank two, mixing tank three, and mixing tank four. The output end of the motor is connected to a drive shaft, and stirring blades are installed on the side of the drive shaft.

[0008] Preferably, the material three-way valve has two valve ports inside, and the valve plate is adapted to the two valve ports.

[0009] Preferably, the outer walls of the first, second, third and fourth mixing tanks are all equipped with vibrators.

[0010] Preferably, both the feed pipe and the static mixing blades are arranged vertically.

[0011] Both the feed pipe and the static mixing blades are vertically arranged.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. Achieve uninterrupted mixing: By alternating the use of multiple mixing tanks and flexibly switching the three-way valve, other mixing tanks can continue to feed and mix while one or a group of mixing tanks are unloading and undergoing subsequent processing, thereby achieving uninterrupted mixing of masterbatch and greatly improving production efficiency. 2. Improve mixing quality: The material is first initially stirred by the stirring blades in the mixing tank, and then further mixed when passing through the static mixing blades. The two mixing processes make the masterbatch more uniformly mixed and improve product quality.

[0013] 3. Easy to operate: The valve plate of the three-way valve is controlled by a cylinder, and the material is unloaded by a pneumatic valve. The degree of automation is high, the operation is simple and convenient, and the intensity of manual operation is reduced.

[0014] 4. Stable and reliable structure: The connections between all components are firm, and the valve plate and valve port of the material three-way valve are compatible, ensuring the stability and sealing of material conveying and reducing the risk of material leakage. At the same time, the vibrator installed on the outer wall of the mixing tank can prevent material from accumulating on the tank wall, ensuring smooth material conveying and mixing.

[0024] Please see Figure 1-4 This utility model provides a technical solution for an uninterrupted masterbatch mixing device: An uninterrupted masterbatch mixing device includes a frame 1. A mixing tank 6, a mixing tank 7, a mixing tank 19, and a mixing tank 20 are respectively installed at the top of the frame 1 for mixing masterbatch. A material three-way valve 11 is installed between the tops of mixing tank 6 and mixing tank 7. A material three-way valve 21 is installed at the top of mixing tank 19 and mixing tank 20. A material three-way valve 22 is installed at the top of material three-way valve 21 and material three-way valve 11. Material three-way valves 11, 21, and 22 are of the same specification, facilitating unified control and maintenance.

[0025] The material three-way valve 11 has two discharge ports 13 at its bottom end, and a valve stem 14 is rotatably connected inside. The valve stem 14 is fixedly connected to a valve plate 12. The material three-way valve 11 has two valve ports inside, and the valve plate 12 is adapted to the two valve ports. The rotation of the valve plate 12 can control the material to enter different mixing tanks. A fixing frame 15 is installed on one side of the material three-way valve 11. A cylinder 16 is hinged to the fixing frame 15. The end of the valve stem 14 protrudes from the surface of the material three-way valve 11 and is fixedly connected to a rotating rod 17. The telescopic end of the cylinder 16 is hinged to the end of the rotating rod 17. The telescopic movement of the cylinder 16 drives the rotating rod 17 and the valve stem 14 to rotate, thereby realizing the rotation control of the valve plate 12.

[0026] Motors 10 are installed at the top of mixing tanks 6, 7, 19, and 20. A drive shaft 9 is connected to the output of each motor 10, and stirring blades 8 are installed on the side of the drive shaft 9. Motors 10 drive the drive shaft 9 and stirring blades 8 to rotate, mixing the materials inside the mixing tanks. Vibrators are installed on the outer walls of mixing tanks 6, 7, 19, and 20 to prevent material accumulation on the tank walls. The four tanks can be arranged in a rectangular pattern, with each tank paired up.

[0027] Pneumatic valves 18 are installed at the bottom of mixing tanks 1-6, 2-7, 3-19, and 4-20. A connecting pipe 3 is connected to the bottom of each pneumatic valve 18. Each pair of connecting pipes 3 has a discharge pipe 4 at its outlet. Static mixing blades 5 are installed inside each discharge pipe 4. Both the discharge pipes 4 and the static mixing blades 5 are vertically arranged to facilitate the smooth passage and mixing of materials under gravity. The static mixing blades 5 are multi-layered, with each layer consisting of cross-shaped blades. The upper and lower layers are deflected at a 45-degree angle to achieve mixing as the materials fall. The number of static mixing blades 5 can be adjusted according to actual usage.

[0028] The working process of this device is as follows: First, the material is fed into the mixing tank 6 through the material three-way valve 22 and the material three-way valve 11. At this time, the cylinder 16 controlling the material three-way valve 11 extends and retracts, driving the rotating rod 17 and the valve stem 14 to rotate, causing the valve plate 12 to open the corresponding valve port of the mixing tank 6, and the material enters the mixing tank 6 through the discharge port 13. The motor 10 is started, driving the transmission shaft 9 and the stirring blades 8 to rotate, stirring the material in the mixing tank 6. At the same time, the vibrator on the outer wall of the mixing tank 6 operates to prevent material accumulation.

[0029] Once mixing tank 6 is full, adjust valve plate 12 of material three-way valve 11 to close the valve port leading to mixing tank 6 and open the valve port leading to mixing tank 7. Material enters mixing tank 7, and motor 10 is started for mixing. When both mixing tank 6 and mixing tank 7 are full, switch the material conveying direction using material three-way valve 22, allowing material to be sequentially fed to mixing tank 19 and mixing tank 20 via material three-way valve 22 and material three-way valve 21. The feeding and mixing process is similar to that for feeding mixing tank 6 and mixing tank 7.

[0030] While feeding materials into mixing tank 3 19 and mixing tank 4 20, the pneumatic valves 18 at the bottom of mixing tank 1 6 and mixing tank 2 7 are opened. The materials that have been initially mixed in mixing tank 1 6 and mixing tank 2 7 enter the discharge pipe 4 through the connecting pipe 3. They are further mixed when flowing through the static mixing blades 5. The mixed materials are discharged from the discharge pipe 4.

[0031] When mixing tanks 19 and 20 are fully loaded, the pneumatic valves 18 at their bottom are opened, allowing the material to be discharged and mixed through the corresponding connecting pipes 3, discharge pipes 4, and static mixing blades 5. At this time, the material conveying direction is switched again through the material three-way valve to feed material to mixing tanks 6 and 7, and so on, to achieve uninterrupted mixing of the masterbatch.

[0032] The above description is merely a preferred embodiment of this utility model and does not limit the scope of protection of this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any changes, modifications, substitutions, integrations, and parameter alterations made to these embodiments within the spirit and principles of this utility model, through conventional substitutions or methods that achieve the same function without departing from the principles and spirit of this utility model, fall within the scope of protection of this utility model.
