Description

Technical Field

[0001] This utility model relates to the field of color masterbatch production and processing technology, specifically a dehumidification device for color masterbatch modification. Background Technology

[0002] Color masterbatch is a plastic colorant made by dispersing a high proportion of pigments or additives with thermoplastic resins. It offers advantages such as superior coloring effects, ease of automatic metering and transportation, energy savings, and zero dust and pollution, making it widely used in the plastics processing industry. Dehumidification is a crucial step in the production of color masterbatch, as the presence of moisture affects its quality and performance, potentially causing clumping and deterioration during storage and use.

[0003] Existing dehumidification equipment for color masterbatches typically involves directly feeding the masterbatches into a drying unit for drying. However, because the masterbatches themselves may contain some moisture, or absorb moisture from the air during storage and transportation, some masterbatches may clump together due to the presence of moisture, forming larger particles or clumps. During the drying process, the internal moisture in these clumps is difficult to evaporate quickly, thus affecting drying efficiency and increasing production time and costs. Therefore, there is an urgent need for a dehumidification device that can effectively solve the problem of drying efficiency being affected by moisture adhesion in color masterbatches. Utility Model Content

[0004] The purpose of this invention is to provide a dehumidification device for color masterbatch modification, so as to solve the problem of low drying efficiency of existing color masterbatch dehumidification devices in the background art when processing sticky color masterbatches.

[0005] A dehumidification device for color masterbatch modification includes a support frame, on which a dehumidification tank and a drying mechanism are mounted. The dehumidification tank is equipped with a spiral feeding mechanism, and the spiral feeding mechanism is equipped with a pushing component.

[0006] The spiral feeding mechanism includes a feed hopper at the bottom of the dehumidification tank, a conveying cylinder inside the dehumidification tank, and a geared motor and driven gear at the top of the dehumidification tank. The bottom of the conveying cylinder is connected to the feed hopper, and discharge ports are opened on both sides of the top of the conveying cylinder. A spiral shaft extending into the conveying cylinder is fixed to the bottom of the driven gear, and spiral blades are provided on the spiral shaft. The bottom of the spiral shaft extends into the feed hopper. The geared motor drives the driven gear to rotate, thereby driving the spiral shaft and spiral blades to rotate, conveying the masterbatch in the feed hopper upward along the conveying cylinder, and finally discharging it from the discharge port.

[0007] The pushing assembly includes a pair of power mechanisms fixed to the two side walls of the conveying cylinder, and a push plate slidably connected around the outside of the conveying cylinder. Each power mechanism includes a support fixed to the conveying cylinder, a geared motor fixed to the support, and a slide cylinder mounted on the support via a support rod. A push rod is slidably connected inside the slide cylinder, and the pair of push rods are respectively fixedly connected to the bottom ends of the push plate. A rotating shaft is provided on the support, with a cam at one end and a driven wheel fixed to the other end. The cam and the push rod are connected via a connecting rod. A driving wheel is fixed to the output shaft of the geared motor. The geared motor drives the driving wheel to rotate, which in turn drives the driven wheel and the rotating shaft to rotate via a belt drive, thereby rotating the cam. The cam, through the connecting rod, pushes the push rod to slide back and forth inside the slide cylinder, thus causing the push plate to reciprocate around the outside of the conveying cylinder, pushing and impacting the masterbatch falling from the outlet.

[0008] The drying mechanism includes a drying chamber mounted on a support frame. Heating tubes and a fan are evenly distributed inside the drying chamber. The heating tubes are made of stainless steel finned heating tubes, and the fan outlet faces inwards towards the dehumidification tank. The heating tubes generate heat, which is then blown into the dehumidification tank by the fan to dehumidify the masterbatch.

[0009] Furthermore, the axis of the discharge port forms an angle of 30°-60° with the axis of the conveying cylinder, and the inner wall of the discharge port is provided with a guide slope, which is adapted to the spiral direction of the spiral blades. This design facilitates the smooth discharge of the masterbatch from the discharge port and allows the masterbatch to fall at a certain angle and speed, making it easier for the pusher plate to impact it.

[0010] Furthermore, the driving wheel and the driven wheel are connected by a belt drive to ensure stable power transmission.

[0011] Furthermore, the outer wall of the dehumidification tank is provided with an insulation layer, which is made of polyurethane foam material and has a thickness of 20-30mm, to reduce heat loss and improve drying efficiency.

[0012] Furthermore, both the geared motor and the geared motor are electrically connected to a control module. The control module is located on the side of the bracket and integrates a frequency converter and a time relay, which facilitates the control and adjustment of the equipment operation.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention uses a spiral feeding mechanism to transport color masterbatch from the feed hopper to the discharge port at the top of the conveying cylinder for unloading. During the unloading process, the pusher plate of the pushing component reciprocates and impacts the falling color masterbatch, breaking apart the color masterbatch that is stuck together due to moisture, thus increasing the contact area between the color masterbatch and the hot air generated by the drying mechanism, thereby improving drying efficiency, shortening drying time, and reducing production costs.

[0025] Example 1

[0026] like Figure 1-6 As shown;

[0027] A dehumidification device for color masterbatch modification.

[0028] This implementation plan addresses the technical problems existing in the prior art, such as those disclosed in the background section above: "Existing masterbatch dehumidification equipment typically sends the masterbatch directly into a drying unit for drying. However, since the masterbatch itself may contain a certain amount of moisture, or absorbs moisture from the air during storage and transportation, some masterbatch may stick together due to the presence of moisture, forming larger particles or clumps. During the drying process, the internal moisture of these sticky masterbatches is difficult to evaporate quickly, thus affecting drying efficiency and increasing production time and costs." In practical terms, this problem is clearly real and difficult to solve. Therefore, to solve this technical problem, a dehumidification device for masterbatch modification is provided.

[0029] like Figure 1-6 As shown in the figure;

[0030] This utility model provides a technical solution: a dehumidification device for color masterbatch modification, including a support frame 1, which supports the entire device. A dehumidification tank 2 and a drying mechanism 3 are mounted on the support frame 1. The dehumidification tank 2 is used to dehumidify the color masterbatch, and the drying mechanism 3 provides hot air to the dehumidification tank 2. A spiral feeding mechanism 4 is installed inside the dehumidification tank 2, which transports the color masterbatch from the bottom to the top of the dehumidification tank 2. A pushing component 5 is installed on the spiral feeding mechanism 4, which pushes and impacts the falling color masterbatch.

[0031] The spiral feeding mechanism 4 includes a feed hopper 41 located at the bottom of the dehumidification tank 2, which receives the masterbatch to be dehumidified. It also includes a conveying cylinder 42 located inside the dehumidification tank 2 and a reduction motor 43 and a driven gear 44 located at the top of the dehumidification tank 2. The bottom of the conveying cylinder 42 is in communication with the feed hopper 41, allowing the masterbatch to enter the conveying cylinder 42 from the feed hopper 41. Discharge ports 45 are located on both sides of the top of the conveying cylinder 42, from which the masterbatch is discharged. A spiral shaft 441 extending into the conveying cylinder 42 is fixed to the bottom of the driven gear 44. Spiral blades 442 are mounted on the spiral shaft 441, and the bottom of the spiral shaft 441 extends into the feed hopper 41. The geared motor 43 drives the driven gear 44 to rotate, thereby driving the spiral shaft 441 and the spiral blade 442 to rotate. The spiral blade 442 conveys the masterbatch in the feed hopper 41 upward along the conveying cylinder 42. Since there are discharge ports 45 on both sides of the top of the conveying cylinder 42, and the axis of the discharge port 45 forms an angle of 30°-60° with the axis of the conveying cylinder 42, and the inner wall is provided with a guide slope that matches the spiral direction of the spiral blade 442, the masterbatch is pushed by the spiral blade 442 and discharged from the discharge port 45 along the guide slope at a certain angle and speed.

[0032] The pushing assembly 5 includes a pair of power mechanisms 51 fixed to the two side walls of the conveying cylinder 42, and a push plate 52 slidably connected to the outer periphery of the conveying cylinder 42. Each power mechanism 51 includes a support 511 fixed to the conveying cylinder 42, a geared motor 512 fixed to the support 511, and a slide cylinder 513 mounted on the support 511 via a support rod. A push rod 514 is slidably connected inside the slide cylinder 513, and the pair of push rods 514 are respectively fixedly connected to the bottom ends of the push plate 52. A rotating shaft 515 is provided on the support 511. A cam 516 is provided at one end of the rotating shaft 515, and a driven wheel 517 is fixed at the other end. The cam 516 and the push rod 514 are connected via a connecting rod 518. A driving wheel 519 is fixed to the output shaft of the geared motor 512, and the driving wheel 519 and the driven wheel 517 are connected via a belt drive. When the geared motor 512 starts, it drives the drive wheel 519 to rotate, which in turn drives the driven wheel 517 and the rotating shaft 515 to rotate via a belt. The rotating shaft 515 drives the cam 516 to rotate. During the rotation, the cam 516 pushes the push rod 514 to slide back and forth inside the slide cylinder 513 via the connecting rod 518, thereby driving the push plate 52 to reciprocate around the outside of the conveying cylinder 42. When the masterbatch falls from the discharge port 45, the reciprocating motion of the push plate 52 pushes and impacts the falling masterbatch, breaking apart any masterbatch that is stuck together.

[0033] The drying mechanism 3 includes a drying chamber mounted on the support 1. Heating tubes and a fan are evenly distributed inside the drying chamber. The heating tubes are made of stainless steel finned heating tubes, and the fan outlet faces inwards towards the dehumidification tank 2. When the heating tubes are energized, they generate heat, which is then blown into the dehumidification tank 2 by the fan to dry and dehumidify the masterbatch. The outer wall of the dehumidification tank 2 is equipped with an insulation layer made of polyurethane foam material, 20-30mm thick, to reduce heat loss and maintain a higher temperature inside the dehumidification tank 2, thereby improving drying efficiency.

[0034] Both geared motor 43 and geared motor 512 are electrically connected to a control module, which is located on the side of the bracket 1. The control module integrates a frequency converter and a time relay. The frequency converter can adjust the speed of geared motor 43 and geared motor 512, thereby controlling the feeding speed of the screw feeding mechanism 4 and the pushing frequency of the pushing component 5; the time relay can set the running time of the equipment to achieve automated control.

[0035] Working Principle: During operation, the color masterbatch to be dehumidified enters through the feed hopper 41. The reduction motor 43 starts, driving the driven gear 44, the spiral shaft 441, and the spiral blades 442 to rotate, conveying the color masterbatch from the feed hopper 41 into the conveying cylinder 42. The masterbatch moves upward along the spiral blades 442 and is finally discharged from the discharge ports 45 on both sides of the top of the conveying cylinder 42. As the color masterbatch falls from the discharge port 45, the reduction motor 512 starts, driving the rotating shaft 515 and cam 516 to rotate through the drive wheel 519, belt, and driven wheel 517. The cam 516 pushes the push rod 514 to slide back and forth in the slide cylinder 513 through the connecting rod 518, causing the push plate 52 to move back and forth around the outside of the conveying cylinder 42, pushing and impacting the falling color masterbatch to break up any sticky masterbatch. At the same time, the heating tube of the drying mechanism 3 is energized and heated, and the fan blows hot air into the dehumidification tank 2 to dry and dehumidify the dispersed color masterbatch. Because the dehumidifier tank 2 has an insulation layer on its outside, heat loss is reduced, and drying efficiency is improved. The control module can control and regulate the operation of the equipment through a frequency converter and a time relay to achieve automated operation.

[0036] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
