Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to an energy-saving drying equipment for producing color masterbatch. Background Technology

[0002] Color masterbatch is an additive used for coloring plastic products, and its application in injection molding has significant advantages. Color masterbatch, after being heated and melted, can be used as injection molding material to create injection molded parts. The production process of color masterbatch requires multiple processing steps, one of which is drying. This drying process is to absorb a certain amount of moisture or volatile substances, preventing the resin or pigments in the color masterbatch from undergoing hydrolysis during high-temperature processing, which would affect the quality of the finished injection molded parts. Currently, the drying process for color masterbatch typically involves placing it in a drying device and blowing hot air to dry it.

[0003] However, common masterbatch drying devices tend to cause adhesion if the masterbatch is not cooled in time after drying, which affects subsequent processing. At the same time, the accumulation of a large amount of masterbatch during the drying process makes it difficult for the masterbatch at the bottom to be heated and dried, reducing the drying effect. In view of this, we propose an energy-saving drying device for masterbatch production. Utility Model Content

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example

[0020] like Figures 1 to 3 As shown, this utility model proposes an energy-saving drying device for color masterbatch production, including an electric drying tank body 1 and a controller 9. Two support plates 2 are sleeved on the outer surface wall of the electric drying tank body 1, providing support for the electric drying tank body 1. A second feed port and a second discharge port are symmetrically opened on the top and bottom walls of the electric drying tank body 1, facilitating the introduction or discharge of color masterbatch into or from the electric drying tank body 1. The electric drying tank body 1 uses electric heating, which is beneficial for drying the color masterbatch entering the electric drying tank body 1. An air inlet and an exhaust port are opened on the other side wall of the electric drying tank body 1, with an exhaust valve 10 inserted into the exhaust port, facilitating the decompression of exhaust gas inside the electric drying tank body 1 and improving the safety of color masterbatch drying operations. A heat preservation cylinder with four positions... The insulation cylinder 4 is positioned between the two electric drying tank bodies 1 and is fitted onto the outer wall of the electric drying tank body 1 for easy rotation. The dimensions of the first feed port and the first discharge port on the insulation cylinder 4 are adapted to the dimensions of the second feed port and the second discharge port. The guide pipe 6 is inserted into the first feed port to facilitate the discharge and feeding of the electric drying tank body 1 through the insulation cylinder 4. Due to the rotational setting of the insulation cylinder 4, the first feed port and the first discharge port can be staggered with the second feed port and the second discharge port during operation, thereby achieving a seal on the electric drying tank body 1. The insulation material of the insulation cylinder 4 is used to achieve a seal and heat preservation of the electric drying tank body 1. The two toothed rings 5 ​​are both set in an incomplete state and are symmetrically fitted onto the outer surface wall of the insulation cylinder 4 to facilitate the rotation and adjustment of the insulation cylinder 4.

[0021] Furthermore, the stirring assembly 3 is installed on the electric drying tank body 1. The stirring assembly 3 includes a motor base 31, a servo motor 32, a first rotating shaft 33, and stirring blades 34. The motor base 31 is fixedly installed on the outer wall of the electric drying tank body 1, and the servo motor 32 is installed on the top of the motor base 31, which supports the servo motor 32. The first rotating shaft 33 is located inside the electric drying tank body 1. Multiple stirring blades 34 are welded to the outer wall of the first rotating shaft 33 in a ring array and are distributed in multiple sets of transverse arrays. The multiple sets of stirring blades 34 are staggered to facilitate subsequent stirring of the electric drying tank body. The color masterbatch in 1 is stirred and dried to improve the uniformity of the color masterbatch during drying and improve the drying effect; one end of the first rotating shaft 33 passes through the side wall of the electric drying tank body 1 and is provided with a first rotating hole, and is connected to the output end of the servo motor 32, which is conducive to rotation under the drive of the servo motor 32; the other end of the first rotating shaft 33 is inserted into the rotating groove opened on the inner side wall of the electric drying tank body 1, and the first sealing bearing and the second sealing bearing arranged in the rotating groove and the first rotating hole are sleeved on the outer surface wall of the first rotating shaft 33, which limits the first rotating shaft 33 and assists the first rotating shaft 33 to rotate in the electric drying tank body 1.

[0022] Furthermore, the drive assembly 7 is installed on the top wall of the two support plates 2. The drive assembly 7 includes a support plate 71, a forward and reverse motor 72, a second rotating shaft 73, and gears 74. The two support plates 71 are fixedly installed on the top wall of the electric drying tank body 1. The two support plates 71 are symmetrically provided with second rotating holes. Bearings are arranged in the two second rotating holes. The two bearings are sleeved on the outer surface wall of the second rotating shaft 73 to assist the second rotating shaft 73 in rotating on the support plate 71. The forward and reverse motor 72 is fixedly installed on the outer wall of one of the support plates 71. The output end of the forward and reverse motor 72 is connected to one end of the second rotating shaft 73 to facilitate driving the second rotating shaft 73 to rotate. The two gears 74 are symmetrically sleeved on the outer surface wall of the second rotating shaft 73 and mesh with the two gear rings 5 ​​to facilitate the rotation of the heat preservation cylinder 4 under the meshing transmission of the gears 74 and gear rings 5, which is beneficial for switching the feeding and working states of the electric drying tank body 1.

[0023] Furthermore, the material collection and cooling assembly 8 is located below the electric drying tank body 1. The material collection and cooling assembly 8 includes a material collection box 81, a breathable filter 82, a door panel 83, a suction fan 84, a central cover 85, a duct 86, a sealing cover 87, and casters 88. The top opening of the material collection box 81 is arc-shaped, and a sliding opening is provided on the side wall of a support plate 2. Multiple casters 88 are installed on the bottom wall of the material collection box 81, which not only supports the material collection box 81 but also facilitates its movement. When in motion, the material collection box 81 can be sent to the bottom of the electric drying tank body 1 through the sliding opening to facilitate the collection of the masterbatch after heating and drying inside the electric drying tank body 1. Ventilation openings are symmetrically provided on the front and back walls of the material collection box 81. Two breathable filters 82 are symmetrically embedded in the corresponding ventilation openings to facilitate dust prevention during ventilation and reduce contamination of the masterbatch inside the material collection box 81 during ventilation and heat dissipation.

[0024] A sealing cover 87 is disposed between two support plates 2. The two side walls of the sealing cover 87 are fixedly connected to the opposite side walls of the two support plates 2. The opening of the sealing cover 87 corresponds to the ventilation port on the back wall of the collection box 81 and is tightly attached to it, which is conducive to subsequent ventilation. The suction fan 84 is fixedly installed at the opening on the back wall of the sealing cover 87, and the collection cover 85 is fixedly installed at the air outlet of the suction fan 84. The air inlet of the air guide pipe 86 is fixedly connected to the air outlet of the collection cover 85, and the air outlet of the air guide pipe 86 is inserted into the air inlet on the side wall of the electric drying tank body 1. This is conducive to cooling the masterbatch in the collection box 81 under the suction of the suction fan 84, reducing the risk of adhesion. At the same time, under the guidance of the air guide pipe 86, it is easy to recover and reuse the waste heat on the dried masterbatch, thereby improving the resource utilization rate.

[0025] In this embodiment, when the masterbatch needs to be dried, the forward and reverse motor 72 is started to drive the second rotating shaft 73 to rotate clockwise, so that the gear 74, in conjunction with the gear ring 5, drives the heat preservation cylinder 4 to rotate. The controller 9 adjusts the guide pipe 6 to correspond to the position of the second inlet, facilitating the introduction of the masterbatch into the electric drying tank body 1. After the material is introduced, the forward and reverse motor 72 is started to rotate in the opposite direction, offsetting the position of the guide pipe 6 from the position of the second inlet, allowing the electric drying tank body 1 to dry the masterbatch. Simultaneously, the servo motor 32 is started to drive the first rotating shaft 33 to rotate the stirring plate 34, which helps to stir the masterbatch, reducing the accumulation of masterbatch and minimizing the heat-receiving area, thus improving the drying effect. When discharge is required after drying, the forward and reverse motor 72 can be started to drive... The second rotating shaft 73 rotates counterclockwise to adjust the positions of the first and second discharge ports to align, allowing the masterbatch to be discharged. The alignment of the first and second discharge ports can be adjusted according to the material discharge requirements to avoid direct full discharge. During the discharge process, the suction fan 84 is activated to draw air, allowing the masterbatch to be rapidly cooled as it falls through the collection box 81. Guided by the collection hood 85, the sealing hood 87, and the air guide pipe 86, the waste heat on the masterbatch is collected and redirected back into the electric drying tank body 1 for reuse, improving energy efficiency. The alignment of the first and second discharge ports can be adjusted during the discharge process. Simultaneously, the rotation of the stirring plate 34 assists in the discharge of the masterbatch, reducing the risk of blockage.
