Description

Technical Field

[0002] The flash evaporation process is a rapid evaporation process in which raw materials are instantaneously evaporated under high temperature and high pressure to form fine particles or thin films. In this process, the color of the product is mainly determined by the nature of the raw materials themselves and the addition amount of masterbatch. By controlling parameters such as the temperature, pressure, and time of flash evaporation, physical properties such as the particle size, shape, and density of the product can be adjusted, thereby affecting the color performance of the product. However, the existing flash evaporation systems have poor control effects on the masterbatch ratio and product color. In addition, the regulation effect of the conventional screw feeding rate is not good, and it is impossible to ensure the feeding uniformity.

[0003] In order to solve the deficiencies of the existing technology, people have carried out long-term explorations and proposed various solutions. For example, a Chinese patent document discloses a feeding mechanism of a flash evaporation dryer [201320293796.5], which includes a fixed frame, a hopper fixed on the fixed frame, a screw for feeding installed at the bottom of the hopper, the screw is connected to the rotating shaft of the motor, the motor is fixed on the fixed frame, the hopper is provided with an outlet connected to the inlet of the flash evaporation dryer, and further includes a pressure rod, which is rotatably fixed on the side wall of the hopper, a passive wheel is fixed at the extending end of the pressure rod, a driving wheel is fixed on the screw, the driving wheel and the passive wheel are driven by a transmission belt, and blades are arranged on the pressure rod.

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-8 As shown, an online color-controllable flash evaporation system includes a horizontally arranged feeding mechanism 1, the feeding mechanism 1 is connected to a vertically arranged masterbatch input mechanism 2, a stirring mechanism 3 is installed between the masterbatch input mechanism 2 and the feeding mechanism 1, the masterbatch input mechanism 2 is equipped with a multi-stage feeding component 4 and a speed regulating component 5, and the feeding mechanism 1 is equipped with a hot melt component 6 and a circulating heat preservation component 7. The masterbatch input mechanism 2 mixes and hot-melts masterbatches of different colors, and the hot-melted slurry is input into the feeding mechanism 1 for further extrusion, and the masterbatch ratio is adjusted in conjunction with an external sensor element to ensure the color performance of the product. In order to ensure the uniformity of the masterbatch and slurry mixing, the stirring mechanism 3 and the multi-stage feeding component 4 are combined to ensure the uniformity of the mixing of the masterbatch at the initial input.

[0020] Specifically, similar to the structure of a conventional extruder, the feeding mechanism 1 in this embodiment includes a feeding barrel 11, a feeding screw 12 is installed in the feeding barrel 11, the feeding barrel 11 is connected to a melt input pipe 13, a feeding motor 14 is installed at the end of the feeding barrel 11 and is transmission-connected to the feeding screw 12, and the other end of the feeding barrel 11 is connected to an extrusion assembly, which adopts a spiral extrusion structure and can effectively control the extrusion rate. The extrusion assembly adjusts the extrusion amount at the outlet end according to design requirements.

[0021] The extrusion assembly controls the extrusion amount in a rotating and staggered manner, specifically including an extrusion cover 15 that closes the port of the feed cylinder 11. Inside the extrusion cover 15, several superimposed flow-limiting disks 16 are rotatably installed. The flow-limiting disks 16 are respectively provided with flow-limiting grooves 17 arranged in central symmetry. A transmission gear set is connected between adjacent flow-limiting disks 16, and the transmission gear set is in transmission connection with a flow-limiting motor 18 installed on the feed cylinder 11. With the transmission of the flow-limiting motor 18 and the transmission gear set, the flow-limiting disks 16 adjust their relative circumferential angles, and their flow-limiting grooves 17 also stagger and adjust the internal flux accordingly. Among them, the flow-limiting grooves 17 can also be replaced by hole shapes in addition to the strip structure.

[0022] Deeply, the masterbatch input mechanism 2 is vertically installed at the upper end of the feeding mechanism 1, specifically including an input pipe 21 connected to the feed cylinder 11. The input pipe 21 is vertically arranged and connected with an input funnel 22. An auxiliary feeding component 8 is installed inside the input pipe 21. The top of the input funnel 22 is closed and provided with a pipeline for the input of the main masterbatch. It is internally provided with multiple groups of sensing elements to monitor the internal temperature and the masterbatch input state in real time.

[0023] Furthermore, the existing masterbatch input mechanism usually adopts a direct injection method. Due to adhesion, the masterbatch is unevenly distributed. If directly input, it will affect the subsequent color adjustment. In order to ensure the even distribution of the masterbatch, the auxiliary feeding component 8 includes an auxiliary pipe 81 connected to the melt input pipe 13. The auxiliary pipe 81 is equipped with a one-way valve 82. The auxiliary pipe 81 is communicated with an auxiliary cavity 83 arranged inside the input pipe 21. A heating cylinder 84 is rotatably installed in the auxiliary cavity 83. Inside the heating cylinder 84, lifting pieces 85 are arranged in a spiral and symmetric manner. An electric heating element and a temperature sensor are installed inside the heating cylinder 84. On the side of the heating cylinder 84 opposite to the inside of the input pipe 21, a rotor 86 made of a permanent magnet material is arranged. The rotor 86 is arranged in central symmetry relative to the heating cylinder 84. An insulating layer 87 is arranged between the inside of the heating cylinder 84 and the rotor 86. On the input pipe 21, a stator 88 arranged in central symmetry and composed of energized coils is installed. The bottom of the auxiliary cavity 83 is communicated with the feed cylinder 11 and is installed with a filter screen 89. The filter screen 89 is in contact with the lower ends of the lifting pieces 85.

[0024] The heating cylinder 84 rotates under the drive of the rotor 86 and the stator 88. The electric heating element inside the heating cylinder 84 starts to melt the masterbatch. The inner lifting pieces 85 stir the slurry to accelerate heat transfer. After being filtered by the filter screen 89, it is directly introduced into the lower feeding mechanism 1. Among them, the auxiliary pipe 81 inputs the main slurry, and the slurry mixes with the masterbatch for heat transfer in the heating cylinder 84.

[0025] Furthermore, in order to guide the masterbatch to be uniformly discharged, the stirring mechanism 3 includes a stirring bracket 31 installed in the input funnel 22, the stirring bracket 31 includes a stirring rod 33 connected to the stirring motor 32, and the stirring rod 33 is installed with a spaced material distribution plate 34 and a material collection plate 35 in the vertical direction, the material distribution plate 34 is conical, the material collection plate 35 is funnel-shaped, and stirring blades 36 are respectively provided on the material distribution plate 34 and the material collection plate 35. The masterbatch is guided to roll down by the stirring blades 36 during the falling process, and a plurality of material distribution plates 34 and material collection plates 35 are combined to realize the intersection of different masterbatches.

[0026] In addition, the conventional multi-stage feed assembly 4 includes a feed tray 41 corresponding to the feed plate 34 and the feed collecting plate 35, the feed tray 41 is connected to a feed pipe 42, a feed channel 43 is provided between the feed tray 41 and the feed pipe 42, the feed tray 41 has a downward feed port 44, the stirring rod 33 is connected to a feed wheel 45 extending into the input hopper 22 of the feed tray 41, the feed wheel 45 has a feed plate 46 arranged in a central symmetric manner, and a relatively independent partition chamber 47 is provided between adjacent feed plates 46 and the feed channel 43. As the stirring rod 33 rotates, the feed plate 46 also rotates and transmits the masterbatch in the input partition chamber 47 in the circumferential direction, and the masterbatch falls evenly from the feed port 44 to the feed plate 34 and the feed collecting plate 35.

[0027] At the same time, the speed regulating assembly 5 controls the feeding rate of the masterbatch, which includes a speed regulating screw 51 rotatably installed in the feeding pipe 42, and the speed regulating screw 51 is connected to the servo motor 52 through a speed change gear set. The rotation of the servo motor 52 drives the speed regulating screw 51 to rotate, so that the masterbatch is transmitted along the axial direction of the feeding pipe 42.

[0028] It can be seen that the hot melt assembly 6 in this embodiment mainly maintains the flow state of the slurry, including a hot melt barrel 61 arranged outside the feeding mechanism 1, a hot melt cavity 62 connected to the feeding mechanism 1 is provided inside the hot melt barrel 61, a pair of hot melt discs 63 are rotatably installed in the hot melt cavity 62, and electric heating blocks 64 arranged in a central symmetric manner are connected between the hot melt discs 63. The electric heating blocks 64 are distributed circumferentially along the hot melt cavity 62, and a hot melt channel 65 is left between the electric heating blocks 64 and the hot melt barrel 61. The hot melt disc 63 is meshed and driven with a rotating motor 66 installed outside the hot melt barrel 61 through a gear ring group, and the electric heating block 64 is connected to an external power supply line through a brush. The hot melt disc 63 rotates relative to disturb the slurry to ensure the uniformity of heat transfer of the electric heating block 64. Since the hot melt cavity 62 flows through the hot melt channel 65 and the inside of the feeding mechanism 1, the internal residual air can be effectively removed.

[0029] Obviously, different from the existing static heat preservation structure, the circulating heat preservation component 7 in this embodiment is combined with the hot melting component 6, specifically including a circulating pipe 71 connected to the outlet of the feeding mechanism 1. The circulating pipe 71 is communicated with the hot melting cylinder 61 through a circulating pump 72. The outside of the feeding mechanism 1 is coated with a heat preservation layer 73, and it is not easy for condensation and blockage to occur inside the feeding mechanism 1 as the slurry circulates.

[0030] Preferably, an image recognition module is equipped at the output end of the feeding mechanism 1. The image recognition module is connected to the main control module to achieve negative feedback regulation, so as to maintain the input stability of the masterbatch and the color performance of the product.

[0031] In summary, the principle of this embodiment is as follows: the feeding mechanism 1 is combined with the masterbatch input mechanism 2, in which the stirring mechanism 3 fully mixes and stirs the masterbatch and the slurry. During the input process of the masterbatch, the multi-stage feeding component 4 and the speed regulating component 5 control the input amount and guide the masterbatch to fall evenly, thereby ensuring the extrusion quality of the product.
