Abstract
Description
Technical Field
[0001] This utility model relates to the field of micro masterbatch processing technology, specifically to a drying device for micro masterbatch processing. Background Technology
[0002] Color masterbatch is a mixture of resin and a large amount of pigment (up to 50%) or dye to form a high-concentration color. Also known as color seed, it is an aggregate made by uniformly loading an excessive amount of pigment or dye into resin. During processing, a small amount of color masterbatch is mixed with uncolored resin to achieve the designed pigment concentration in the resin or product. However, processing color masterbatch into other products requires it to reach a certain degree of dryness; therefore, drying treatment is necessary during its processing.
[0003] In the prior art, a Chinese patent document with publication number CN219359958U and publication date of July 18, 2023, was proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: A drying device for color masterbatch processing includes a body, a feeding port is provided on the top of the body, and a first feeding plate, a second feeding plate and a stirring feeding device are arranged sequentially from top to bottom inside the body; the first feeding plate and the second feeding plate have the same structure, the first feeding plate is evenly provided with feeding holes, a heating device is provided inside the first feeding plate, and a vibration motor is provided at the bottom of both the first feeding plate and the second feeding plate.
[0004] To address the drying issue in masterbatch processing, existing technology employs a first and second air inlet to introduce hot air for drying. The first air inlet is positioned between the first and second discharge trays to heat the masterbatch on the first discharge tray. This, combined with the heating device on the first discharge tray, enables a dual drying process. However, the introduced hot air lacks filtration capabilities, allowing impurities from the outside air to be drawn into the heating tube by the fan, causing blockages. Furthermore, these impurities can integrate with the masterbatch itself, negatively impacting its production quality. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-5As shown, this utility model provides a drying device for micro color masterbatch processing, including a drying box 1. A feed inlet 2 is fixedly connected to the upper right side of the top of the drying box 1, and a discharge outlet 3 is opened on the upper right side of the bottom of the drying box 1. Support legs 4 are fixedly installed on all four sides of the bottom of the drying box 1. A screening unit is set inside the drying box 1, and a heating unit is set on the upper right side of the drying box 1. The screening unit includes a screening screen plate 11 fixedly installed on the inner wall of the right side of the drying box 1. A guide plate 12 is fixedly connected to the bottom of the screening screen plate 11. A discharge pipe 13 is fixedly installed on the other end of the guide plate 12 on the upper right side of the drying box 1. A screening screen plate 14 is fixedly installed on the inner wall of the left side of the drying box 1 below the guide plate 12. A guide cavity 15 is opened at the bottom of the interior of the drying box 1. A guide port 16 is opened on the left side shell of the drying box 1 at the output end of the guide cavity 15.
[0027] Furthermore, the masterbatch is screened by setting a screening screen plate 11. The inclined angle of the screening screen plate 11 causes the masterbatch to roll continuously. During the rolling process, the masterbatch is screened by the screen plate, so that the broken particles are separated. The masterbatch rolls from the top of the screening screen plate 11 to the top of the screening screen plate 14 for secondary screening. The broken particles fall through the mesh into the guide plate 12 and the guide cavity 15, and roll along their inclined angle. The broken particles are discharged to the outside by the discharge pipe 13 and the guide port 16. The screened masterbatch is discharged to the outside by the discharge port 3. Example
[0028] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the heating unit includes a heating cylinder 18 fixedly installed on the right side of the drying oven 1. A partition plate 111 is fixedly installed on the inner wall of the heating cylinder 18. A support bracket 17 is fixedly connected to the bottom end of the heating cylinder 18. Exhaust holes 117 are provided at both ends of the right side of the partition plate 111. A support frame 112 is fixedly installed inside the heating cylinder 18 on the right side of the partition plate 111. A servo motor 113 is fixedly installed at the rear end of the support frame 112. The output end of the servo motor 113 extends to the front end of the support frame 112 and is fixedly sleeved with an exhaust fan 1. 14. The right end of the heating cylinder 18 is provided with mounting slots 115 at both the front and rear of the exhaust fan 114. A filter screen plate 116 is movably inserted into the mounting slot 115. An electric heating tube 118 is fixedly installed in the middle of the left side of the partition plate 111. An exhaust pipe 119 is fixedly installed on the output end of the exhaust port 117 of the partition plate 111. The other end of the exhaust pipe 119 extends to the upper and lower ends of the left side of the heating cylinder 18. A conveying pipe 19 is fixedly connected to the other end of the exhaust pipe 119. A heat exhaust cover 110 is fixedly installed on the other end of the conveying pipe 19. The heat exhaust cover 110 is fixedly installed at the upper and lower openings on the right side of the drying oven 1.
[0029] Furthermore, the output of the servo motor 113 drives the exhaust fan 114 to rotate at a constant speed, drawing outside air into the heating cylinder 18. The filter screen 116 filters impurities in the gas. The gas continuously flows into the exhaust pipe 119 through the exhaust port 117. The exhaust pipe 119 is coiled in a ring around the outer surface of the electric heating tube 118. The heat source of the electric heating tube 118 heats the gas inside the exhaust pipe 119. The ring coiling arrangement can increase the heating time and promote the heating effect. The hot gas flows into the conveying pipe 19 and the heat exhaust cover 110. The heat exhaust cover 110 discharges the gas into the drying chamber 1. As the masterbatch continuously rolls, the hot gas dries the moisture inside the masterbatch, promoting the drying of the masterbatch.
[0030] The working principle of this micro-drying device for color masterbatch processing will be explained in detail below.
[0031] like Figure 1-5 As shown, during use, the masterbatch is fed into the drying chamber 1 through the feed inlet 2. The masterbatch enters the drying chamber 1 and falls onto the top of the screening screen 11. Due to its inclined angle, the masterbatch continuously rolls, and during this rolling process, it is screened by the screen, separating the broken particles. The masterbatch rolls from the top of the screening screen 11 to the top of the screening screen 14 for secondary screening. The broken particles fall through the mesh into the guide plate 12 and the guide cavity 15, again rolling along their inclined angle. The broken particles are discharged to the outside through the discharge pipe 13 and the guide port 16. The screened masterbatch is discharged out through the discharge port 3. During the screening process, the servo motor 1... The output end of 13 drives the exhaust fan 114 to rotate at a constant speed, drawing outside air into the heating cylinder 18. The filter screen 116 filters impurities in the gas. The gas continuously flows into the exhaust pipe 119 through the exhaust port 117. The exhaust pipe 119 is coiled in a ring around the outer surface of the electric heating tube 118. The heat source of the electric heating tube 118 is used to heat the gas inside the exhaust pipe 119. The ring coiling arrangement can increase the heating time and promote the heating effect. The hot gas flows into the conveying pipe 19 and the heat exhaust cover 110. The heat exhaust cover 110 discharges it into the drying chamber 1. As the masterbatch continuously rolls, the hot gas dries the moisture inside the masterbatch, promoting the drying of the masterbatch.
[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
