Description

Technical Field

[0001] This utility model belongs to the field of polyurethane resin coating preparation technology, and particularly relates to a heating device for preparing polyurethane resin coatings. Background Technology

[0002] In the preparation of polyurethane resin coatings, heating and stirring are carried out in a reaction vessel. In a broad sense, a reaction vessel is a container in which physical or chemical reactions occur. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-to-high-speed mixing functions required by the process can be achieved.

[0003] Because conventional reactors are heated externally and from the outside in, with only one side heating inwards, they suffer from significant heat loss.

[0004] To address this issue, we propose a heating device for preparing polyurethane resin coatings. Utility Model Content

[0005] The purpose of this invention is to solve the problem of severe heat loss in conventional reaction vessels, and to propose a heating device for the preparation of polyurethane resin coatings.

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

[0007] A heating device for preparing polyurethane resin coatings includes a motor, a vessel lid fixedly connected to the motor housing, a support rotatably mounted on the lower part of the vessel lid, a mating fastener fixedly connected to the motor rotor, and a reaction vessel body fixedly connected to the lower part of the support. A stirring claw is rotatably mounted inside the reaction vessel body, and a heating rod is provided in the gap of the stirring claw. The heating rod is threaded onto the reaction vessel body and penetrates through it. A knob is fixedly connected to the outside of the heating rod, sealing between the heating rod and the reaction vessel body. The mating fastener engages with the stirring claw. The motor and heating rod are electrically connected to an external power source. Material is poured into the reaction vessel body, and the vessel lid is closed, aligning the mating fastener with the stirring claw. The motor drives the mating fastener to rotate, which in turn drives the stirring claw to rotate, causing it to stir the internal material. Simultaneously, the heating rod heats the internal material. By placing the heating rod inside the material, the heat conduction ratio is increased, thereby reducing heat loss and improving energy utilization.

[0008] Preferably, the lid is externally fixed with a handle. The handle allows for convenient manual operation to open or close the lid.

[0009] Preferably, the reactor body includes an outer shell and a threaded ring, the threaded ring being uniformly and fixedly connected to the outside of the outer shell; the lower part of the support is fixedly connected to the outer shell, the heating rod is threadedly installed inside the threaded ring, the heating rod movably passes through the outer shell, and the knob is sealed on the threaded ring. Using the threaded ring to thread the heating rod allows it to be disassembled or reinstalled, facilitating maintenance or replacement.

[0010] Preferably, the stirring claw includes a rotating column and stirring blades, with the stirring blades evenly and fixedly connected to the outside of the rotating column; the lower end of the rotating column is rotatably connected to the bottom of the outer shell, and the upper end of the rotating column is fastened to a mating buckle; the heating rod is located within the gap between the stirring blades. When the mating buckle drives the rotating column to rotate, the rotating column drives the stirring blades to revolve, using the stirring blades to agitate the material inside the outer shell, and using the heating rod to impede the vortex flow, thus facilitating the stirring of the material.

[0011] Preferably, the heating rod includes a heating rod body and an annular threaded seat, the annular threaded seat being fixedly connected to the tail of the heating rod body; the heating rod body movably penetrates the outer shell, the annular threaded seat is threaded into a threaded ring, the heating rod body is located in the gap between the stirring blades, and the end of the annular threaded seat facing away from the heating rod body is fixedly connected to a knob. The annular threaded seat can be unscrewed from the threaded ring, and the heating rod body can be pulled out; conversely, the heating rod body can be reinstalled into the outer shell, facilitating the assembly or disassembly of the heating rod.

[0012] Preferably, the knob includes a sealing ring and a rotating ring, with one end of the sealing ring fixedly connected to the rotating ring; the annular threaded seat passes through the sealing ring and is fixedly connected to the rotating ring, with the sealing ring sealing between the rotating ring and the threaded ring. Operating the rotating ring causes the annular threaded seat to rotate, tightening it onto the threaded ring, thus pressing the sealing ring tightly against the threaded ring, facilitating the sealing of the gap between the threaded ring and the annular threaded seat.

[0013] Preferably, the knob further includes a hexagonal ring, which is fixedly connected to the outside of the rotating ring. By operating the hexagonal ring with a wrench, the hexagonal ring acts on the rotating ring, facilitating further tightening of the heating rod via the knob using the wrench.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] 1. Pour the material into the reactor body, then close the reactor lid, so that the coupling buckle and the stirring claw are connected. Use the motor to drive the coupling buckle to rotate, which in turn drives the stirring claw to rotate, so that the stirring claw stirs the material inside. At the same time, use the heating rod to heat the material inside. By placing the heating rod inside the material, the heat conduction ratio of the material is increased, thereby reducing the heat loss rate and improving the energy utilization rate.

[0016] 2. The heating rod is installed using a threaded ring, which allows the heating rod to be disassembled or reinstalled, facilitating maintenance or replacement of the heating rod.

[0017] 3. When the connecting buckle drives the rotating column to rotate, the rotating column drives the stirring blade to revolve. The stirring blade stirs the material inside the outer shell, and the heating rod hinders the vortex, making it convenient to stir the material.

[0018] 4. Unscrew the annular threaded seat from the threaded ring, then pull out the heating rod body. Conversely, reinstall the heating rod body into the outer shell for easy assembly or disassembly of the heating rod.

[0019] 5. Operate the rotating ring to drive the annular threaded seat to rotate, tighten the annular threaded seat onto the threaded ring, so that the rotating ring presses the sealing ring onto the threaded ring, which facilitates sealing the gap between the threaded ring and the annular threaded seat.

[0020] 6. Use a wrench to rotate the hexagonal ring. The hexagonal ring acts on the rotating ring, making it easy to tighten the heating rod further by using the wrench and the knob. Attached Figure Description
