Description

Technical Field

[0001] This utility model relates to the field of drying oven technology, specifically to a vapor phase rust inhibitor masterbatch drying oven. Background Technology

[0002] Vapor phase corrosion inhibitor masterbatch is a functional resin masterbatch made from polyethylene or LLDPE as a carrier, composite VCI vapor phase corrosion inhibitor, and auxiliary additives through a special process. It is mainly used in the production of vapor phase corrosion inhibitor plastic films, and can be used to create packaging materials with metal rust-proofing capabilities through blown film processing. Its rust-proofing mechanism involves releasing corrosion-inhibiting components to form a protective film on the metal surface, preventing current flow and limiting the activity of cations / water ions, thereby achieving a rust-proof period of 2-5 years. It is suitable for the protection of multiple metals such as steel, copper, and aluminum alloys.

[0003] During the production and processing of vapor phase corrosion inhibitor masterbatch, a drying oven is used to remove residual moisture from its surface. Traditional drying ovens do not have an automatic shut-off function and the hot air blower is usually turned off by timer or manual means. If the drying effect of vapor phase corrosion inhibitor masterbatch is achieved, but the hot air blower is not turned off in time, it will lead to the problem of wasted electricity.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a vapor phase rust inhibitor masterbatch drying oven, comprising:

[0024] The drying oven body 1 has a door panel 11 rotatably connected to the front of the drying oven body 1, an observation window 12 is fixedly installed on the inner wall of the door panel 11, and a support leg 13 is fixedly installed at the bottom of the drying oven body 1.

[0025] Monitoring-type drying mechanism 2 is installed on the main body 1 of the drying chamber and is used to dry the material.

[0026] Heat recovery mechanism 3 is located on the right side of the drying chamber body 1. Heat recovery mechanism 3 is used to recover heat from the inside of the hot exhaust gas.

[0027] The monitoring-type drying mechanism 2 includes a controller 21, a hot air blower 23, and an exhaust pipe 28. The controller 21 is fixedly installed on the left side of the drying chamber body 1, and an indicator light 22 is fixedly installed on the top of the controller 21. The hot air blower 23 is fixedly connected to the top of the drying chamber body 1, and the exhaust pipe 28 is fixedly connected to the bottom of the drying chamber body 1. A through hole 281 is opened on the right side of the exhaust pipe 28, and a cover plate 282 is threadedly connected to the inner wall of the through hole 281. A cover plate 282 is fixedly installed on the left side of the cover plate 282, located inside the cavity of the exhaust pipe 28. The humidity sensor 283 controls the operation of the hot air blower 23, which delivers hot air into the inner cavity of the drying chamber 1 for drying the vapor phase rust inhibitor masterbatch. The hot exhaust gas is discharged through the inner cavity of the exhaust pipe 28. The humidity sensor 283 monitors the humidity of the discharged hot exhaust gas and feeds the humidity data back to the controller 21. When the humidity is lower than a preset value, it indicates that the vapor phase rust inhibitor masterbatch has been effectively dried. The controller 21 then shuts off the hot air blower 23 and turns on the indicator light 22. The user is prompted that the controller 21, indicator light 22, hot air blower 23, and humidity sensor 283 in this solution are devices that can be purchased commercially by those skilled in the art. No structural modifications have been made to these devices in this paper. Therefore, those skilled in the art are familiar with their working principles based on their professional knowledge and can apply them proficiently. Thus, this paper will not elaborate further on this aspect. Furthermore, this solution aims to protect the physical structure, not the circuitry or software control. The mention of the processing circuit in this paper is merely a supplementary explanation of the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuitry technology. It is worth emphasizing that although this solution does not elaborate on the electronic control program, those skilled in the art can be familiar with and apply it based on their professional knowledge. By rotating the device, the cover plate 282 and humidity sensor 283 can be disassembled and reassembled at the through hole 281, facilitating cleaning of the humidity sensor 283 or replacement if it is damaged.

[0028] As one implementation method in this embodiment, such as Figure 2 As shown, the monitoring drying mechanism 2 also includes an annular component 24 and a support block 27. The annular component 24 is fixedly installed on the top of the drying chamber body 1. A plug ring 25 is movably inserted into the top of the annular component 24. A stainless steel filter cover 26 is fixedly connected to the top of the plug ring 25. Through the design of the stainless steel filter cover 26, the hot air blower 23 can be wrapped and protected, and the air absorbed by the hot air blower 23 can be filtered to ensure the safe operation of the hot air blower 23. Pulling the plug ring 25 out from the top of the annular component 24 completes the disassembly of the stainless steel filter cover 26, and the stainless steel filter cover 26 can then be cleaned.

[0029] As one implementation method in this embodiment, such as Figure 2As shown, the support block 27 is fixedly installed on the inner wall of the drying chamber body 1. A material frame 271 is movably inserted into the top of the support block 27. A mesh plate 272 is fixedly installed on the inner wall of the material frame 271 near the bottom. In use, vapor phase rust inhibitor masterbatch can be added into the inner cavity of the material frame 271, and then the material frame 271 is inserted into the support block 27. Hot air can pass through the mesh plate 272 for circulation, resulting in good drying efficiency.

[0030] As one implementation method in this embodiment, such as Figure 4 As shown, the heat recovery mechanism 3 includes a water tank 31, which is fixedly installed on the right side of the drying chamber body 1. A water inlet valve 32 is fixedly connected to the right side of the water tank 31 near the top, and a drain valve 33 is fixedly connected to the right side of the water tank 31 near the bottom. A digital display water temperature gauge 34 is fixedly installed on the right side of the water tank 31. A copper pipe 35 is fixedly connected between the top and bottom of the inner wall of the water tank 31. The water inlet valve 32 is connected to an external cold water source, and the drain valve 33 is connected to an external hot water recovery pipe. By controlling the opening of the water inlet valve 32, cold water can be added to the inner cavity of the water tank 31. Hot exhaust gas will flow through the inner cavity of the copper pipe 35 and heat the cold water, thus realizing the heat recovery function. The digital display water temperature gauge 34 is an existing device used to measure and display the water temperature inside the water tank 31. When the user observes that the water temperature has risen to a usable level, the water can be changed. By controlling the opening of the drain valve 33, hot water can be released, and then the water inlet valve 32 can be opened to replenish cold water.

[0031] As one implementation method in this embodiment, such as Figure 4 As shown, connection boxes 36 are fixedly installed on the top and bottom of the water tank 31. A first connection cover 37 is movably inserted into the inner cavity of the lower connection box 36. A first hose 38 is fixedly connected to the bottom of the first connection cover 37. The first hose 38 is fixedly connected to the top of the exhaust pipe 28. Holes corresponding to copper pipes 35 are opened on the top and bottom of the water tank 31. If it is necessary to clean the inner cavity of the copper pipe 35, first loosen the bolts on the connection box 36, and then pull out the second connection cover 39 and the first connection cover 37 from the inner cavity of the connection box 36. Then, an external cylindrical brush can be inserted into the inside of the copper pipe 35 for cleaning. After cleaning, the first connection cover 37 and the second connection cover 39 can be reset.

[0032] As one implementation method in this embodiment, such as Figure 4 As shown, a second connecting cover 39 is movably inserted into the inner cavity of the upper connecting box 36. A second flexible hose 391 is fixedly connected to the top of the second connecting cover 39. The actual length of the second flexible hose 391 is designed according to the usage environment, so that the exhaust gas can be discharged in the specified direction.

[0033] Working principle: During use, vapor phase rust inhibitor masterbatch is added to the inner cavity of the material frame 271, and then the material frame 271 is inserted into the support block 27. The hot air blower 23 is controlled to operate, which can deliver hot air into the inner cavity of the drying chamber 1 for drying the vapor phase rust inhibitor masterbatch. The hot air can pass through the mesh plate 272 for circulation, resulting in good drying efficiency. The hot exhaust gas will be discharged through the inner cavity of the exhaust pipe 28. Through the design of the humidity sensor 283, the humidity of the discharged hot exhaust gas can be monitored, and the humidity data can be fed back to the controller 21. When the humidity is lower than the preset value, it indicates that the vapor phase rust inhibitor masterbatch has been effectively dried. The controller 21 will control the hot air blower 23 to turn off and control the indicator light 22 to turn on to remind the user. The water valve 32 is pre-controlled to open, which can add cold water into the inner cavity of the water tank 31. The hot exhaust gas will pass through the inner cavity of the copper pipe 35 for circulation, and the hot exhaust gas will be discharged through the inner cavity of the copper pipe 35 for drying.

[0034] The exhaust gas will heat the cold water, thus achieving the function of heat recovery.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
