A dissolving tank for polyurethane resin production

Abstract

This utility model relates to the field of polyurethane resin production technology, specifically a dissolving tank for polyurethane resin production, including a base. When using this dissolving tank, the device is connected to a factory power supply. First, the polyurethane resin raw material is placed into the dissolving tank. Then, motor number two is turned on, and through the meshing transmission of gear one and gear two, the angle of the crossbar and stirring assembly is adjusted to a suitable stirring position. Next, motor number one is started, driving the rotating shaft and stirring paddle to rotate and stir the raw material. Heating is required during the dissolving process; an electric heating tube can be turned on to heat the material in the dissolving tank through the jacket, accelerating the dissolution. Once the resin is completely dissolved, an electric push rod is activated. The output end of the electric push rod pushes the rotating frame, which causes the dissolving tank to rotate around the top of the support, gradually tilting it to discharge the dissolved polyurethane resin solution from the tilting plate, completing the entire dissolution and discharge process.

Description

Technical Field

[0001] This utility model relates to the field of polyurethane resin production technology, and in particular to a dissolving tank for polyurethane resin production. Background Technology

[0002] Polyurethane resins possess excellent wear resistance, corrosion resistance, and elasticity, making them widely used in various industries such as construction, automotive, furniture, and footwear. In the production process of polyurethane resins, the dissolution of raw materials is a crucial step. Traditional dissolution equipment often suffers from problems such as uneven stirring, low dissolution efficiency, and inconvenient solution discharge, failing to meet the requirements of modern large-scale production for both the quality and efficiency of polyurethane resins. Furthermore, different types of polyurethane resins have different requirements for temperature and other conditions during dissolution, which existing dissolution equipment struggles to adjust flexibly. Therefore, there is an urgent need for a more sophisticated and higher-performance dissolution system.

[0003] To address the problems of traditional dissolving equipment, the design requirements for this dissolving tank mainly include: first, achieving efficient and uniform stirring to accelerate the dissolution rate of polyurethane resin and ensure dissolution quality; second, having a heating function to adjust the temperature according to the dissolution requirements of different resins; third, facilitating the discharge of the solution after dissolution to reduce manual labor intensity and safety risks; and fourth, ensuring a stable and reliable overall structure that is easy to install and maintain, thereby improving production efficiency, reducing production costs, and meeting the growing production needs of polyurethane resin manufacturers.

[0004] Therefore, we propose a dissolving tank for the production of polyurethane resin. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dissolving tank for polyurethane resin production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dissolving tank for polyurethane resin production includes a base, an electrically operated telescopic rod fixedly mounted on the upper surface of the base, a crossbar rotatably connected to the top of the telescopic rod, a steering assembly mounted at the bottom of the crossbar, a stirring assembly mounted at the end of the crossbar away from the steering assembly, a dissolving tank movably mounted below the stirring assembly, the dissolving tank having a dissolving trough, a tilting plate fixedly mounted at the top of the dissolving tank, a jacketed section within the dissolving tank, a plurality of electrically heated tubes fixedly mounted inside the jacketed section, and a tilting assembly mounted on the side of the dissolving tank away from the electrically operated telescopic rod.

[0008] As a further embodiment of this utility model: the tilting assembly includes a bracket, and two brackets are fixedly installed on the upper surface of the base plate. The two brackets are triangular, and two support rods are rotatably connected to the top of the two brackets. A rotating frame is fixedly installed on one side of the two support rods that are close to each other. The rotating frame is H-shaped.

[0009] As a further embodiment of this utility model: a support plate is fixedly installed on one side of the bottom of the rotating frame, the support plate is fixedly connected to the dissolving tank, and a clamp is fixedly installed on the side of the rotating frame near the electric telescopic rod, the clamp being fixedly sleeved on the outside of the dissolving tank.

[0010] As a further embodiment of this utility model: an electric push rod is rotatably connected to the upper surface of the base, and the output end of the electric push rod is rotatably connected to the rotating frame.

[0011] As a further embodiment of this utility model: the stirring assembly includes a No. 1 motor, the No. 1 motor is fixedly installed on the upper surface of the crossbar, the lower surface of the crossbar is rotatably connected to a rotating shaft, the rotating shaft is fixedly connected to the output end of the No. 1 motor, and two stirring paddles are fixedly installed on both sides of the bottom end of the rotating shaft.

[0012] As a further embodiment of this utility model: the steering assembly includes gears, a first gear is fixedly installed on the outside of the top of the electric telescopic rod, and a second gear is meshed with the first gear near the rotating shaft.

[0013] As a further embodiment of this utility model: a second motor is fixedly installed on the upper surface of the crossbar away from the first motor, and the output end of the second motor is fixedly connected to the second gear.

[0014] Compared with the prior art, this utility model provides a dissolving tank for polyurethane resin production, which has the following beneficial effects:

[0015] 1. This utility model employs a stirring assembly with a No. 1 motor driving a rotating shaft. Stirring paddles are fixedly installed on both sides of the bottom of the rotating shaft, which can thoroughly stir the polyurethane resin raw materials in the dissolving tank, accelerating the dissolution process. The steering component further optimizes the stirring effect. Gear 1 and Gear 2 mesh on the outer side of the top of the electric telescopic rod, and Gear 2 is driven to rotate by a No. 2 motor, thereby adjusting the angle of the crossbar and stirring assembly to achieve multi-angle, all-around stirring. This design effectively avoids incomplete dissolution in certain areas during the dissolution process. Compared with traditional dissolution equipment that stirs in only one direction, it significantly improves the dissolution efficiency and quality of polyurethane resin, ensures the uniformity of raw material mixing during production, and provides a better foundation for subsequent polyurethane resin processing and production.

[0016] 2. In this utility model, the electric push rod on the base cooperates with the rotating frame. The rotating frame is securely connected to the dissolving tank through a support plate and a clamp. When it is necessary to discharge the dissolved polyurethane resin solution, the electric push rod is activated, pushing the rotating frame to rotate around the top of the support, thereby tilting and pouring the dissolving tank. This design makes the solution discharge operation more convenient and efficient, reducing the safety risks and waste caused by manual handling and pouring. Several electric heating tubes installed inside the jacket of the dissolving tank can heat the material in the dissolving tank. The temperature can be adjusted according to the temperature conditions required for polyurethane resin dissolution, creating a suitable temperature environment for resin dissolution and further improving the dissolution effect. This multifunctional design that integrates heating, stirring, and convenient pouring has strong practicality and innovation in the field of polyurethane resin production.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description
