Description

Technical Field

[0001] This utility model belongs to the field of color masterbatch production technology, and more specifically, it relates to a vacuum drying device for color masterbatch. Background Technology

[0002] In the production of color masterbatch, in order to remove moisture, solvents or other volatile substances from the color masterbatch and ensure product quality and stability, a double cone rotary vacuum dryer is often used for low-temperature drying. The double cone rotary vacuum dryer heats evenly and is suitable for granular and powdered color masterbatch, especially for easily oxidized and heat-sensitive materials. Existing double cone rotary vacuum dryers generally consist of a base support, a double cone rotary container, a vacuum system, a heating system and a transmission system.

[0003] Existing application number: CN201720965394.3, this utility model discloses a rotary vacuum dryer, including a frame, a rotary tank, a far-infrared electric heater, a rotating mechanism, a supply pipeline, a return pipeline, a vacuuming mechanism, and a drive motor. The rotary tank is mounted on the frame via the rotating mechanism. A jacket through which a heat-retaining medium passes is located within the cylinder wall of the rotary tank. The far-infrared electric heater is mounted on the outer wall of the rotary tank. The supply pipeline and the return pipeline are both connected to the jacket. The vacuuming mechanism is located on one side of the rotary tank and extends into the tank. The drive motor is connected to the rotating mechanism. Through this method, the rotary vacuum dryer of this utility model, by employing a far-infrared electric heater for heating and drying, improves the heat transfer system of the material, accelerates the drying rate, effectively reduces energy consumption, saves production costs, and allows for temperature adjustment, featuring precise temperature control and a long service life.

[0004] Based on the above, the double cone rotary vacuum dryer cannot observe the rolling uniformity, wall adhesion, color change and drying degree of the masterbatch in real time during the drying process. It can only rely on preset time or experience to judge, lacking intuitive monitoring of the material state and timely handling of abnormal situations, which may lead to insufficient drying or over-drying. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a vacuum drying device for color masterbatch. This device solves the problem that existing double-cone rotary vacuum dryers cannot monitor the uniformity of color masterbatch tumbling, wall adhesion, color changes, and degree of drying in real time during the drying process. Instead, they rely on preset times or experience to make judgments, lacking intuitive monitoring of the material's state and the ability to handle abnormal situations in a timely manner, which may lead to insufficient or excessive drying.

[0006] The purpose and effect of this utility model's vacuum drying equipment for masterbatch are achieved through the following specific technical means:

[0007] A vacuum drying device for color masterbatch includes a support frame, a rotating container, an observation window, a transmission box, a through-hole, a sealed door, a real-time observation component, and a convenient sampling component. The rotating container is rotatably connected inside two support frames. The observation window is located inside the front of the rotating container. The transmission box is fixedly connected inside the rotating container. The through-hole is fixedly connected to the bottom of the rotating container. The sealed door is hinged to the front of the through-hole. The real-time observation component is located behind the observation window. The convenient sampling component is located inside the through-hole.

[0008] Furthermore, the real-time observation component includes: an operating handwheel and a drive bevel gear; the operating handwheel is rotatably connected to the bottom of the rotating container; the drive bevel gear is disposed inside the transmission box and is coaxially and fixedly connected to the rear of the operating handwheel.

[0009] Furthermore, the real-time observation component also includes: a driven bevel gear and a transmission screw; the driven bevel gear is rotatably connected inside the transmission box, and the driven bevel gear meshes with the driving bevel gear; the transmission screw is rotatably connected inside the rotating container, and the transmission screw is coaxially fixedly connected above the driven bevel gear.

[0010] Furthermore, the real-time observation component also includes: a guide rod, a first connector, and a second connector; the guide rod is fixedly connected inside the rotating container; the first connector is slidably connected to the outside of the guide rod; and the second connector is threadedly connected to the outside of the transmission screw.

[0011] Furthermore, the real-time observation component also includes a scraper and a light; the scraper is fixedly connected to the front end of the first connector and the second connector; the light is fixedly connected to the rear of the scraper.

[0012] Furthermore, the convenient sampling component includes: a first sampling tube, a second sampling tube, and an operating crossbar; the first sampling tube is inserted into the through-hole; the second sampling tube is rotatably connected inside the first sampling tube; and the operating crossbar is fixedly connected inside the front end of the second sampling tube.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, an observation window is set in front of the rotating container to promptly detect any abnormalities that occur during the drying of the masterbatch inside the rotating container. A real-time observation component is also provided. When masterbatch debris adheres to the inner surface of the observation window, the operating handwheel is turned to move the scraper up and down along the guide rod to scrape off the debris. The lighting behind the scraper moves synchronously to provide auxiliary lighting, ensuring a clear field of vision.

[0015] Secondly, sampling does not require stopping the machine. After opening the sealed door, rotate the operating lever to make the slots of the first sampling cylinder and the second sampling cylinder overlap, and the material can enter the second sampling cylinder. After stopping the machine, the first sampling cylinder can be pulled out and the sample can be poured out. This completely changes the traditional method of stopping the machine to break the vacuum for sampling. During the sampling process, the sealed door is only opened briefly and there is no need to destroy the vacuum environment inside the rotating container. The operation time is greatly shortened, and the impact of frequent start and stop of the vacuum environment on the stability of the material is avoided.

[0016] This invention features an observation window and real-time observation components in front of the rotating container, enabling clear real-time monitoring of the drying state. Through the convenient sampling components inside the nozzle, samples can be quickly taken in a vacuum environment without stopping the machine. This not only significantly improves the visualization and controllability of the production process and reduces material quality fluctuations and production capacity waste caused by observation delays or sampling shutdowns, but also provides data support for process parameter optimization through real-time monitoring and efficient sampling.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example 1:

[0027] As attached Figure 1 To be continued Figure 6 As shown:

[0028] This utility model provides a vacuum drying device for color masterbatch, including a support 1, a rotating container 2, an observation window 3, a transmission box 4, a through port 11, a sealing door 1101, and a real-time observation component; the rotating container 2 is rotatably connected inside the two supports 1; the observation window 3 is located inside the front of the rotating container 2; the transmission box 4 is fixedly connected inside the rotating container 2; the through port 11 is fixedly connected to the bottom of the rotating container 2; the sealing door 1101 is hinged to the front of the through port 11; and the real-time observation component is located behind the observation window 3.

[0029] The real-time observation component includes: an operating handwheel 5 and a drive bevel gear 501; the operating handwheel 5 is rotatably connected to the bottom of the rotary container 2; the drive bevel gear 501 is located inside the transmission box 4 and is coaxially fixedly connected to the rear of the operating handwheel 5.

[0030] The real-time observation component also includes: a driven bevel gear 6 and a transmission screw 601; the driven bevel gear 6 is rotatably connected inside the transmission box 4 and meshes with the driving bevel gear 501; the transmission screw 601 is rotatably connected inside the rotary container 2 and is coaxially fixedly connected above the driven bevel gear 6.

[0031] The real-time observation component also includes: a guide rod 7, a first connector 8, and a second connector 9; the guide rod 7 is fixedly connected inside the rotary container 2; the first connector 8 is slidably connected to the outside of the guide rod 7; and the second connector 9 is threadedly connected to the outside of the transmission screw 601.

[0032] The real-time observation component also includes a scraper 10 and a lighting lamp 1001; the scraper 10 is fixedly connected to the front end of the first connector 8 and the second connector 9; the lighting lamp 1001 is fixedly connected to the rear of the scraper 10.

[0033] The specific usage and function of this embodiment: When using this device, if it is necessary to observe the drying state of the masterbatch inside the rotary container 2, first rotate the rotary container 2 ninety degrees so that the observation window 3 faces upwards. The drying state of the masterbatch inside the rotary container 2 can then be observed through the observation window 3. If masterbatch particles or debris adhere to the inner surface of the observation window 3, making the observation unclear, the operating handwheel 5 can be rotated. This will drive the transmission screw 601 through the bevel gear transmission mechanism formed by the meshing of the driven bevel gear 6 and the driving bevel gear 501, in the guide rod 7 and... Guided by the first connecting member 8, the transmission screw 601, together with the second connecting member 9, drives the scraper 10 to move up and down through a threaded transmission mechanism. This effectively scrapes away the colored masterbatch particles or debris adhering to the inner surface of the observation window 3, ensuring a clear field of vision. The scraper 10 is made of high-temperature resistant, high-strength silicone material, ensuring its service life within the rotating container 2 and preventing damage to the inner surface of the observation window 3. As the scraper 10 moves, the lighting lamp 1001 moves along with it, serving as auxiliary lighting to ensure that the situation inside the observation window 3 is clearly visible.

[0034] Example 2:

[0035] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 6 It also includes a convenient sampling component, which is located inside the through-port 11.

[0036] The convenient sampling component includes: a first sampling cylinder 12, a second sampling cylinder 13, and an operating crossbar 1301; the first sampling cylinder 12 is inserted into the inside of the through-hole 11; the second sampling cylinder 13 is rotatably connected inside the first sampling cylinder 12; and the operating crossbar 1301 is fixedly connected inside the front end of the second sampling cylinder 13.

[0037] The specific usage and function of this embodiment are as follows: When it is necessary to sample the masterbatch material in the rotary container 2, there is no need to wait for the entire equipment to stop. Simply open the sealing door 1101, and then rotate the operating lever 1301 to drive the second sampling cylinder 13 to rotate. Both the second sampling cylinder 13 and the first sampling cylinder 12 have a corresponding slot. When the two slots are rotated to overlap, the masterbatch material enters the second sampling cylinder 13 through this slot. Then, rotate the operating lever 1301 again to misalign the two slots, so that the currently sampled masterbatch material can be temporarily stored in the second sampling cylinder 13. After that, close the sealing door 1101. Compared with the traditional sampling with the machine stopped, this method causes less damage to the vacuum environment in the rotary container 2 and is quick and easy. After the equipment stops, open the sealing door 1101 again, pull the first sampling cylinder 12 forward, and then rotate the operating lever 1301 to overlap the two slots to pour out the sampled masterbatch material.
