Description

Technical Field

[0001] This utility model relates to the field of epoxy resin insulation technology, specifically to an insulation device used in the production of modified epoxy resin. Background Technology

[0002] Epoxy resin is a high molecular weight polymer, referring to a class of polymers containing two or more epoxy groups in their molecules. It is a condensation product of epichlorohydrin and bisphenol A or polyols. Due to the chemical reactivity of epoxy groups, it can be ring-opened by various compounds containing active hydrogen, and then cured and cross-linked to form a network structure. If epoxy resin is not properly insulated before processing and use, it may cure prematurely due to temperature changes, making it unusable. It is necessary to use an insulation device to control the temperature and keep the epoxy resin within a suitable temperature range to effectively prevent premature curing.

[0003] Existing technologies use direct heating to maintain the temperature of epoxy resin raw materials during insulation. However, due to the poor fluidity and slow heat conduction of epoxy resin, uneven heat distribution occurs, which can affect subsequent processing. Therefore, we propose an insulation device for the production of modified epoxy resin. Utility Model Content

A main heat-conducting cylinder is fixed in the middle of the bottom surface of the lifting plate, and multiple auxiliary heat-conducting cylinders connected to it are fixed in the outer ring. The cylinders are filled with heat-conducting oil and can be heated and inserted into different positions inside the epoxy resin, thereby uniformly heating and preserving the epoxy resin and avoiding the problem of uneven temperature affecting subsequent processing. This solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat preservation device for the production of modified epoxy resin, comprising a heat preservation tank and a lifting plate, wherein the lifting plate is located inside the heat preservation tank and the upper surface of the lifting plate is flush with the upper surface of the heat preservation tank; a main heat-conducting cylinder is vertically fixed at the bottom center of the lifting plate, and multiple secondary heat-conducting cylinders are vertically fixed at the bottom of the lifting plate outside the main heat-conducting cylinder, the main heat-conducting cylinder and the secondary heat-conducting cylinders are connected by a guide tube, and an electric heater is vertically installed inside the main heat-conducting cylinder, and the interiors of the main heat-conducting cylinder, the secondary heat-conducting cylinders and the guide tubes are filled with heat-conducting oil.

[0006] By adopting the above technical solution, after the epoxy resin is placed inside the heat preservation tank, the electric heater is started to heat the heat transfer oil inside the main heat transfer cylinder and the auxiliary heat transfer cylinder. Since the main heat transfer cylinder and the auxiliary heat transfer cylinder are directly inserted into various parts inside the epoxy resin, the epoxy resin can be heated and kept warm evenly, so that the heat distribution is as uniform as possible.

[0010] By adopting the above technical solution, both the lifting plate and its bottom structure can be raised and lowered. After use, the lifting plate and its bottom structure can be raised to a higher height for easy cleaning.

[0011] Optionally, the bottom two sides of the horizontal plate are vertically fixed with support rods, and the horizontal plate is supported and fixed above the heat preservation tank by the support rods.

[0012] Optionally, a discharge pipe is provided at the bottom center of the heat preservation tank, and the discharge pipe is connected to the interior of the heat preservation tank.

[0014] Optionally, the bottom outer side of the insulated tank is vertically supported by a support leg, and multiple support legs are provided.

[0015] By adopting the above technical solution, the insulated tank is stably supported on the ground by its feet.

[0016] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows: 1. The technical solution of this application has a main heat-conducting cylinder fixed in the middle of the bottom surface of the lifting plate, and multiple auxiliary heat-conducting cylinders connected to it are fixed on the outer ring. The cylinders are filled with heat-conducting oil and can be heated and inserted into different positions inside the epoxy resin, thereby uniformly heating and keeping the epoxy resin warm, avoiding the problem of uneven temperature affecting subsequent processing.

[0017] 2.

[0020] Please see Figure 1-2 This utility model provides a technical solution: a heat preservation device for the production of modified epoxy resin, including a heat preservation tank 1 and a lifting plate 3. The bottom outer side of the heat preservation tank 1 is vertically supported by a support leg 11. Multiple support legs 11 are provided, and the support legs 11 are of the same height, which can achieve stable support for the heat preservation tank 1. A discharge pipe 12 is provided at the middle position of the bottom of the heat preservation tank 1. The discharge pipe 12 is connected to the inside of the heat preservation tank 1. In use, the discharge pipe 12 is connected to a discharge pipe containing a valve. When the epoxy resin is stored in heat preservation mode, the valve is kept closed. When the epoxy resin needs to be discharged for subsequent processing, the valve is opened to discharge the epoxy resin from the discharge pipe.

[0021] The lifting plate 3 is located inside the upper part of the heat preservation tank 1, and the upper surface of the lifting plate 3 is flush with the upper surface of the heat preservation tank 1. A main heat-conducting cylinder 31 is vertically fixed at the middle of the bottom of the lifting plate 3. Multiple auxiliary heat-conducting cylinders 32 are vertically fixed at the bottom of the lifting plate 3 outside the main heat-conducting cylinder 31. The main heat-conducting cylinder 31 and the auxiliary heat-conducting cylinders 32 are connected by a guide cylinder 33. An electric heater 311 is vertically installed inside the main heat-conducting cylinder 31. The main heat-conducting cylinder 31, the auxiliary heat-conducting cylinders 32 and the guide cylinder 33 are filled with heat-conducting oil. The bottom of the main heat-conducting cylinder 31 and the auxiliary heat-conducting cylinders 32 are placed inside the heat preservation tank 1.

[0022] When in use, epoxy resin is directly added to the interior of the insulation tank 1. At this time, the main heat-conducting cylinder 31 and the auxiliary heat-conducting cylinder 32 are inserted into various parts of the epoxy resin. When the electric heater 311 heats the heat-conducting oil inside the main heat-conducting cylinder 31, the heat is transferred to the auxiliary heat-conducting cylinder 32 through the heat-conducting oil inside the heat-conducting cylinder 33 under the action of heat conduction. Thus, the main heat-conducting cylinder 31 and the auxiliary heat-conducting cylinder 32, which are inserted at different positions inside the epoxy resin, heat and insulate the epoxy resin more evenly. The heater also includes a temperature sensor, which can monitor the temperature of the heat-conducting oil. A probe-type temperature sensor can also be inserted inside the epoxy resin to monitor the real-time temperature of the epoxy resin during insulation.

[0023] A heat-conducting plate 321 is vertically fixed on the outer surface of the auxiliary heat-conducting cylinder 32. Each auxiliary heat-conducting cylinder 32 is provided with at least two heat-conducting plates 321. This arrangement allows for a larger contact area between the auxiliary heat-conducting cylinder 32 and the epoxy resin, which is beneficial for better heat conduction to the epoxy resin and for heat preservation.

[0024] During use, epoxy resin will adhere to the surfaces of the main heat-conducting cylinder 31, the secondary heat-conducting cylinder 32, and the inner wall of the insulation tank 1. To facilitate cleaning, the lifting plate 3 is positioned above the interior of the insulation tank 1 and can be raised and lowered. A horizontal plate 2 supports the top of the insulation tank 1, and support rods 21 are vertically fixed on both sides of the bottom of the horizontal plate 2. The horizontal plate 2 is supported and fixed above the insulation tank 1 by the support rods 21. An electric push rod 22 is installed in the middle of the surface of the horizontal plate 2, and the bottom end of the electric push rod 22 is fixed to the upper surface of the lifting plate 3. After each storage of epoxy resin, the electric push rod 22 can be used to raise the lifting plate 3, thereby raising the main heat-conducting cylinder 31 and the secondary heat-conducting cylinder 32, so that the main heat-conducting cylinder 31, the secondary heat-conducting cylinder 32, and the inner wall of the insulation tank 1 can be easily rinsed.

[0025] In use, a discharge pipe with a valve is installed on the discharge pipe 12. The electric actuator 22 and the electric heater 311 are both connected to the industrial control equipment and powered on. The epoxy resin to be processed is put into the heat preservation tank 1. The electric heater 311 is started to heat the heat transfer oil inside the main heat-conducting cylinder 31. Under the action of heat conduction, the heat is transferred through the heat transfer oil inside the guide cylinder 33 to the auxiliary heat-conducting cylinder 32. Thus, the main heat-conducting cylinder 31 and the auxiliary heat-conducting cylinder 32, which are inserted at different positions inside the epoxy resin, provide more uniform heating and heat preservation for the epoxy resin. When further processing of the epoxy resin is required, the discharge pipe 12 with a valve can be opened. The valve on the discharge pipe allows epoxy resin to be discharged from the discharge pipe 12. When there is no epoxy resin inside the insulation tank 1, the electric heater 311 needs to be stopped. Each time epoxy resin is stored, the electric push rod 22 can be used to raise the lifting plate 3, which in turn raises the main heat-conducting cylinder 31 and the auxiliary heat-conducting cylinder 32. This allows for easy rinsing of the main heat-conducting cylinder 31, the auxiliary heat-conducting cylinder 32, and the inner wall of the insulation tank 1. The wastewater after rinsing is discharged from the discharge pipe 12. After rinsing, the electric push rod 22 is used to lower the lifting plate 3, placing the main heat-conducting cylinder 31 and the auxiliary heat-conducting cylinder 32 inside the insulation tank 1.
