Description

Technical Field

[0001] This utility model relates to the field of stirred tank bodies, specifically to a stirred tank for easy feeding of epoxy resin. Background Technology

[0002] In chemical material production operations, it is often necessary to stir and mix chemical raw materials. The stirred tank body is the most common stirring and mixing device. The twin-shaft dispersion tank is widely used in the production of chemical products such as inks, pigments, pesticides, and adhesives. It is mainly used for mixing liquid and colloidal fluid materials, breaking down, dispersing, mixing, and stirring some materials that are originally immiscible. Currently, the existing stirred tank body structure has poor stirring and dispersion effect on liquid materials, resulting in poor thermal conductivity, easy precipitation, and high viscosity of the chemical raw materials after stirring, which greatly affects work efficiency. In addition, the existing tank body has poor external sealing performance and cannot guarantee stirring and sealing.

[0003] Chinese Patent No. CN201921260358.2 discloses a lubricating oil mixing device that facilitates material feeding. When using the mixing device, the rotating ring is first rotated to drive the protrusion to rotate, causing the protrusion to move downward. After the protrusion moves downward, the block on it is disengaged from the port of the connecting pipe. Then, the material pipe is connected above the connecting pipe, allowing the raw material to flow into the interior of the mixing vessel body through the opening in the connecting pipe and the cavity. Then, the rotating ring is rotated in the opposite direction to make the protrusion fit tightly against the material pipe.

[0004] The applicant discovered the following technical problems when implementing the above-mentioned technical solution: However, the above-mentioned mixing equipment is only suitable for mixing fluids with low viscosity. When mixing epoxy resin with high viscosity, it is often necessary to open the mixing tank body and then pour the epoxy resin with high viscosity into the mixing tank body for mixing. Otherwise, the epoxy resin with high viscosity will become viscous in the pipeline and it will be difficult to enter the mixing tank body, which increases the workload and reduces the work efficiency.

[0005] Therefore, the problem that this invention urgently needs to solve is to provide an epoxy resin mixing vessel that can overcome the viscosity of high-viscosity epoxy resin in the pipeline and improve its rate of entry into the mixing vessel body. Utility Model Content

[0006] To address the aforementioned technical problems, the purpose of this invention is to overcome the limitations of existing mixing equipment, which is only suitable for mixing fluids with low viscosity. When mixing epoxy resins with higher viscosity, it is often necessary to open the mixing vessel body before pouring the resin into it. Otherwise, the high-viscosity epoxy resin will become viscous in the pipes, making it difficult to enter the mixing vessel body, increasing workload and reducing efficiency. Therefore, this invention provides a mixing vessel for epoxy resin that overcomes the viscous nature of high-viscosity epoxy resin in the pipes, thereby increasing its rate of entry into the mixing vessel body and facilitating feeding.

[0007] To achieve the above objectives, this utility model provides a mixing tank for easy feeding of epoxy resin. The mixing tank for easy feeding of epoxy resin includes: a mixing tank body; a feed pipe, which is connected to the upper part of the mixing tank body and its interior; a drive mechanism; an extrusion feeding mechanism, which is provided on one side of the feed pipe and on the other side of the extrusion feeding mechanism; and a rotating inner tube, which is used to connect the feed pipe and the discharge pipe, and is rotatably fitted inside the feed pipe and the discharge pipe by means of the drive mechanism. The inner wall of the rotating inner tube is also provided with an internally threaded block with the conveying direction facing the interior of the mixing tank body.

[0008] Preferably, a mounting frame is provided above the mixing vessel body, the first drive motor is mounted on the mounting frame, and its output end extends into the mixing vessel body and is provided with a stirring rod.

[0009] Preferably, a sealing structure is provided at the connection between the stirring rod and the stirring vessel body.

[0010] Preferably, the extrusion feeding mechanism includes: a housing, which is inclinedly disposed on one side of the feed pipe, and has a discharge pipe at one end near the rotating inner tube and a feed inlet at the other end; a second drive motor; and a feeding screw, which is inclinedly and rotatably disposed inside the housing via the second drive motor.

[0011] Preferably, the driving mechanism includes: a first transmission gear, wherein the stirring rod is coaxially arranged with the first transmission gear on the portion of the rod body above the stirring vessel body; and a second transmission gear, wherein the rotating inner tube body is coaxially arranged with a second transmission gear that meshes with the first transmission gear.

[0012] Preferably, the second transmission gear is provided with locking ring blocks on opposite sides, and the feed pipe opening and the discharge pipe opening are respectively provided with locking ring grooves adapted to the locking ring blocks.

[0013] Preferably, the first transmission gear can be a bevel gear, helical gear, or spur gear, and the second transmission gear can be a bevel gear, helical gear, or spur gear that meshes with the first transmission gear.

[0014] According to the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: This application adds a highly viscous epoxy resin composite material into the feed inlet, and then starts the second drive motor to drive the conveying screw to rotate, so as to transport the highly viscous epoxy resin composite material to the discharge pipe. Since the conveying screw cannot enter the discharge pipe to stir and transport the highly viscous epoxy resin composite material, blockage and sticking may occur; at the same time, by starting the first drive motor to drive the stirring rod to stir the highly viscous epoxy resin composite material inside the stirring vessel body, the stirring will drive the second drive gear to rotate synchronously through the first transmission gear, thereby driving the rotating inner tube to rotate synchronously, and then through the internal thread block to stir the highly viscous epoxy resin composite material inside the discharge pipe and the feed pipe. The highly viscous epoxy resin composite material is agitated and conveyed to prevent it from sticking in the pipeline and blocking the entry of subsequent epoxy resin composite material into the mixing vessel. A level sensor is also installed inside the mixing vessel. When the level sensor detects that the mixing vessel is filled with sufficient epoxy resin composite material, it controls the second drive motor via the PLC controller to stop conveying epoxy resin composite material. After the epoxy resin composite material in the mixing vessel is fully agitated, it is discharged through the discharge port of the mixing vessel. Then, the level sensor, via the PLC controller, controls the second drive motor to continue conveying epoxy resin composite material. This overcomes the stickiness of highly viscous epoxy resin in the pipeline, thereby increasing its entry rate into the mixing vessel and improving the working efficiency of the mixing vessel.

[0022] Reference Figure 1 , Figure 3 A mixing vessel for easy feeding of epoxy resin, comprising: a mixing vessel body 1; a feed pipe 2, wherein the feed pipe 2 is provided above the mixing vessel body 1 and communicates with its interior; a drive mechanism 3; an extrusion feeding mechanism, wherein the extrusion feeding mechanism is provided on one side of the feed pipe 2 and the extrusion feeding mechanism is provided on one side of the extrusion feeding mechanism; and a rotating inner tube 4, wherein the rotating inner tube 4 is used to connect the feed pipe 2 and the discharge pipe 502, and is rotatably fitted inside the feed pipe 2 and the discharge pipe 502 by means of the drive mechanism 3, and the inner wall of the rotating inner tube 4 is also provided with an internally threaded block 401 with the conveying direction facing the interior of the mixing vessel body 1.

[0023] Reference Figure 2 An mounting frame 101 is suspended above the mixing vessel body 1. The first drive motor 102 is mounted on the mounting frame 101, and its output end extends into the mixing vessel body 1 and is equipped with a stirring rod 103.

[0024] A sealing structure is provided at the connection between the stirring rod 103 and the stirring vessel body 1.

[0025] The sealing structure of the stirred tank body 1 in this application uses mechanical seals, rotary shaft seals, and other means, which are existing technologies and will not be described in detail here.

[0026] Reference Figure 1 The extrusion feeding mechanism includes: a housing 501, which is inclinedly disposed on one side of the feed pipe 2, and has a discharge pipe 502 at one end near the rotating inner tube 4 and a feed inlet 503 at the other end; a second drive motor 504; and a feeding screw, which is inclinedly and rotatably disposed inside the housing 501 via the second drive motor 504.

[0027] Reference Figure 4 The driving mechanism 3 includes: a first transmission gear 301, wherein the stirring rod 103 is coaxially mounted on the upper part of the stirring vessel body 1; and a second transmission gear 302, wherein the rotating inner tube 4 is coaxially mounted on the tube body and meshes with the first transmission gear 301.

[0028] Reference Figure 3The second transmission gear 302 is coaxially provided with snap-fit ​​ring blocks 402 on both sides. The opening of the feed pipe 2 and the opening of the discharge pipe 502 are coaxially provided with snap-fit ​​ring grooves 201 that are adapted to the snap-fit ​​ring blocks 402.

[0029] In this application, the rotating inner tube 4 connects the feed pipe 2 and the discharge pipe 502 through the snap-fit ​​rings 402 on both sides of the second transmission gear 302, while ensuring its own rotation.

[0030] The first transmission gear 301 can be a bevel gear, helical gear, or spur gear, and the second transmission gear 302 can be a bevel gear, helical gear, or spur gear that meshes with the first transmission gear 301.

[0031] The first transmission gear 301 and the second transmission gear 302 of this application can be meshing bevel gears, helical gears, spur gears, etc., depending on the actual situation.

[0032] In use, the device provided by this utility model adds a highly viscous epoxy resin composite material into the inlet 503, and then starts the second drive motor 504 to drive the conveying screw to rotate, so as to transport the highly viscous epoxy resin composite material to the outlet pipe 502. Since the conveying screw cannot enter the outlet pipe 502 to agitate and transport the highly viscous epoxy resin composite material, blockage or sticking may occur. At the same time, the first drive motor 102 is started to drive the stirring rod 103 to stir the highly viscous epoxy resin composite material inside the stirring vessel body 1. During stirring, the first transmission gear 301 drives the second transmission gear 302 to rotate synchronously, thereby driving the rotating inner tube 4 to rotate synchronously, and then through the internal thread block 401 to stir the highly viscous epoxy resin composite material inside the outlet pipe 502 and the inlet pipe 2. The highly viscous epoxy resin composite material is stirred and conveyed to prevent it from sticking in the pipeline and blocking the subsequent epoxy resin composite material from entering the mixing tank body 1. The mixing tank body 1 is also equipped with a liquid level sensor. When the liquid level sensor detects that the mixing tank body 1 is full of sufficient epoxy resin composite material, it will control the second drive motor 504 to stop the continued conveying of epoxy resin composite material through the PLC controller. After the epoxy resin composite material in the mixing tank body 1 has been stirred, it is discharged through the discharge port of the mixing tank body 1. Then, the liquid level sensor will control the second drive motor 504 to continue conveying epoxy resin composite material through the PLC controller. This overcomes the stickiness of the highly viscous epoxy resin in the pipeline, thereby improving its entry rate into the mixing tank body 1 and the working efficiency of the mixing tank body 1.
