Description

Technical Field

[0001] The utility model relates to the technical field of sizing and drying, in particular to a sizing and drying device for mica paper. Background Art

[0002] Mica plates are made by bonding mica paper with silicone glue, heating, and pressing. Among them, the mica content is about 90%, and the silicone glue content is 10%. During the sizing process of mica paper, a drying device is required to dry the glue to a semi-dry state, thereby reducing the waiting time for the glue to solidify after the mica paper is bonded.

[0003] The patent with the application number 202320539340.6 discloses a drying device, which includes a cylinder with open ends at both ends and a cylinder cover; several air ducts are arranged inside the cylinder wall of the cylinder, and the air outlets of the air ducts lead into the cylinder cavity; the cylinder cover is provided with a hot air cavity with a built-in hot air component, several air inlet holes leading to the hot air cavity are arranged on the top surface of the cylinder cover, and air outlet holes are arranged at the bottom of the cylinder cover and are connected to the air inlets of the air ducts. The U-shaped or arc-shaped air ducts guide the direction of the hot air and enhance the drying effect; through the air net, the hot air is cut into several strands to further enhance the drying effect.

[0004] However, in this technical solution, since the outside air is connected to the inside of the drying device, the temperature inside the drying device decreases again under the influence of the outside air after it rises, resulting in the heating device needing to be in a high-load heating state all the time, with high drying energy consumption and low drying efficiency. Moreover, a sealed drying device will cause a large amount of water vapor to appear. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a sizing and drying device for mica paper in view of the deficiencies of the prior art. Through the cylindrical drying chamber structure and the cooperation of the air pump with the heating plate and the moisture-absorbing cotton structure, the function of circulating dry air in the drying chamber is realized, and the problems of high energy consumption and low drying efficiency caused by the leakage of drying heat are solved.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A sizing and drying device for mica paper, which includes a drying box and a plurality of air pumps fixed on the outer wall of the drying box. A cylindrical drying chamber is opened at the central position of the drying box, and feeding grooves connected to the drying chamber are opened at both ends of the drying box. Scraper plates are elastically inserted into the bottom walls of the two feeding grooves. An installation groove is opened on one side of the inner wall of the drying chamber, and a heating plate is fixed on the other side of the inner wall of the drying chamber. A water storage tank is opened at the bottom wall of the drying chamber, and a moisture-absorbing cotton is damped and inserted into the installation groove.

[0007] Preferably, a diversion frame is fixedly inclined at the top end of the drying box, and heat preservation conveying pipes are fixedly connected to both ends of the air pump. The two heat preservation conveying pipes are respectively connected to the bottom of the drying box and the diversion frame.

[0008] Furthermore, a mica paper body is arranged between the two feeding grooves, and telescopic grooves are formed in the bottom walls of the two feeding grooves.

[0009] Even further, springs are embedded and installed in the telescopic grooves, and the scraping plates are slidably inserted into the telescopic grooves

[0010] Even further, a storage box is fixedly connected to the side wall of the drying box, and a return flow groove in an L-shaped structure communicating with the storage box is formed in the bottom wall of one of the feeding grooves.

[0011] Even further, a sizing roller is embedded in the storage box, and a motor connected to the sizing roller is installed on the side wall of the storage box.

[0012] Even further, a drain pipe communicating with the storage tank is fixedly connected to the bottom end of the drying box, and a solenoid valve is installed on the drain pipe.

[0013] The beneficial effects of the present utility model are as follows:

[0014] (1) In the present utility model, a cylindrical drying cavity is arranged in the drying box. The air pump on the outer wall of the drying box enables air to be conveyed between the diversion frame and the drying cavity through the heat preservation conveying pipe. The diversion frame enables the air to flow along the inner wall of the drying cavity and come into contact with the heating plate during the flowing process, and the generated hot air dries the glue at the bottom of the mica paper body. The water vapor generated after drying is absorbed by the moisture-absorbing cotton and flows along the inner wall of the trapezoidal structure installation groove to the water storage tank, enabling the hot air to circulate and flow in a relatively closed environment, reducing the drying energy consumption, improving the drying efficiency, and simultaneously reducing the water vapor content in the circulating air.

[0015] (2) In the present utility model, telescopic grooves are formed in the inner walls of the feeding grooves. The springs in the telescopic grooves push the scraping plates to scrape off the excess glue at the bottom of the mica paper and enable the glue to flow into the storage box along the return flow groove. At the same time, the scraping plates reduce the space in the feeding grooves, thereby improving the sealing and heat preservation effects of the drying box. By opening the control valve on the drain pipe, it is convenient to discharge the water in the water storage tank.

[0016] In summary, the present utility model has the advantages of reducing the drying energy consumption, improving the drying efficiency, and simultaneously reducing the water vapor content in the circulating air. Description of the Drawings

A drying chamber 18 with a cylindrical structure is opened at the central position of the drying box 1, and feeding grooves 11 communicating with the drying chamber 18 are opened at both ends of the drying box 1. Scrapers 12 are elastically inserted into the bottom walls of the two feeding grooves 11. An installation groove 9 is opened on one side of the inner wall of the drying chamber 18, and a heating plate 19 is fixed on the other side of the inner wall of the drying chamber 18. A water storage tank 16 is opened at the bottom wall of the drying chamber 18, and a moisture absorbent cotton 10 is dampingly inserted into the installation groove 9. After removing the moisture absorbent cotton 10, it can be replaced and dried.

[0026] A diversion frame 2 is inclined and fixed at the top of the drying box 1. Both ends of the air pump 4 are fixed with heat preservation conveying pipes 3. The two heat preservation conveying pipes 3 are respectively connected to the bottom of the drying box 1 and the diversion frame 2. A mica paper main body 8 is arranged between the two feeding grooves 11, and telescopic grooves 13 are opened at the bottom walls of the two feeding grooves 11. The air pump 4 on the outer wall of the drying box 1 makes the air flow between the diversion frame 2 and the drying chamber 18 through the heat preservation conveying pipe 3. The diversion frame 2 makes the air flow along the inner wall of the drying chamber 18 and contact with the heating plate 19 during the flowing process. The generated hot air dries the glue at the bottom of the mica paper main body 8. The water vapor generated after drying is absorbed by the moisture absorbent cotton 10 and flows into the water storage tank 16 along the inner wall of the installation groove 9 with a trapezoidal structure, so that the hot air circulates in a relatively closed environment, reducing the drying energy consumption and improving the drying efficiency.

[0027] Embodiment Two

[0028] As Figure 3 and Figure 4 shown, the same or corresponding components as those in Embodiment One adopt the corresponding reference numerals in Embodiment One. For the sake of simplicity, only the differences from Embodiment One will be described below. The difference between this Embodiment Two and Embodiment One is that: a spring 14 is embedded in the telescopic groove 13, the scraper 12 is slidably inserted into the telescopic groove 13, a storage box 6 is fixed on the side wall of the drying box 1, a return flow groove 15 with an L-shaped structure communicating with the storage box 6 is opened at the bottom wall of one of the feeding grooves 11, a sizing roller 5 is embedded in the storage box 6, and a motor 7 connected to the sizing roller 5 is installed on the side wall of the storage box 6. The spring 14 in the telescopic groove 13 pushes the scraper 12 to scrape off the excess glue at the bottom of the mica paper and make the glue flow into the storage box 6 along the return flow groove 15. At the same time, the scraper 12 reduces the space in the feeding groove 11, thereby improving the sealing and heat preservation effects of the drying box 1. A drain pipe 17 communicating with the storage tank is fixed at the bottom end of the drying box 1, and a solenoid valve is installed on the drain pipe 17.

The spring 14 in the telescopic groove 13 pushes the scraper 12 to scrape off the excess glue at the bottom of the mica paper, and the glue flows along the return groove 15 to the storage tank 6. At the same time, the scraper 12 reduces the space in the feeding groove 11. The air pump 4 on the outer wall of the drying box 1 makes the air flow between the guide frame 2 and the drying chamber 18 through the heat preservation conveying pipe 3. The guide frame 2 makes the air flow along the inner wall of the drying chamber 18 and contacts the heating plate 19 during the flow. The generated hot air dries the glue at the bottom of the mica paper main body 8. The water vapor generated after drying is absorbed by the moisture-absorbing cotton 10 and flows along the inner wall of the trapezoidal structure mounting groove 9 to the water storage tank 16, enabling the hot air to circulate in a relatively closed environment, reducing the drying energy consumption, improving the drying efficiency, and at the same time reducing the water vapor content in the circulating air.
