[0029] 3. The setting of the lifting mechanism can circulate the masterbatch and make it in a flowing state before storage, so that it can be fully exposed to the flowing air and fully cooled and dried.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0038] Example 1

[0039] like Figure 1 As shown, the masterbatch cooling and drying integrated device includes:

[0040] The tank body 10 is provided with a feed port at the upper end and a discharge port at the lower end. The interior of the tank body 10 is provided with a buffer chamber 11, a mixing chamber 12 and a storage chamber 13 from top to bottom.

[0041] A buffer mechanism 30 is provided inside the buffer chamber 11 , and the buffer mechanism 30 includes a spiral plate 31 connected to the inner wall of the tank body 10 ;

[0042] A mixing mechanism 40 is disposed inside the mixing chamber 12, and the mixing mechanism 40 includes a rotating stirring blade 43;

[0043] The ventilation mechanism includes a blowing assembly 51 provided at the bottom of the storage chamber 13 and a suction assembly 52 provided at the junction of the mixing chamber 12 and the storage chamber 13. The blowing assembly 51 blows air into the tank body 10, and the suction assembly 52 draws air out of the tank body 10, thereby driving the air flow inside the tank body 10. The direction of the gas flow is as follows: Figure 1 The arrows in the figure indicate the direction;

[0044] The material is put into the tank 10 from the open end, first rotated down by the spiral plate 31, and then broken up by the rotating stirring blades 43 and falls into the storage chamber 13. During the process of the masterbatch being put into the tank 10, the masterbatch is fully contacted with the flowing air flow to cool and dry the masterbatch.

[0045] The method for using the masterbatch cooling and drying integrated device comprises the following steps:

[0046] S1. Equipment preparation: The stirring blade 43 in the mixing mechanism 40 is adjusted to the rotating state; the blowing assembly 51 in the ventilation mechanism is adjusted to the state of blowing air into the interior of the tank 10, and the suction assembly 52 is adjusted to the state of exhausting air to the outside of the tank 10;

[0047] S2. Masterbatch input: The masterbatch to be cooled and dried is input from the feed port of the tank 10, first rotated down by the spiral plate 31, and then broken up by the rotating stirring blade 43 and dropped into the storage chamber 13. In the process of inputting the masterbatch, the masterbatch is fully exposed to the flowing air flow to cool and dry the masterbatch;

[0048] S3. Masterbatch storage: The cooled and dried masterbatch is stored inside the tank 10 .

[0049] In the technical solution of the integrated masterbatch cooling and drying device, after the masterbatch enters the tank body 10, it rotates downward through the spiral plate 31, which extends the travel path of the masterbatch when it is put in and increases the contact time with the flowing airflow; after sliding from the spiral plate 31, it is broken up by the rotating stirring blades 43, which increases the distribution range of the masterbatch inside the tank body 10 and the contact area with the flowing airflow; when the initially prepared masterbatch is put into the tank body 10, the heat of the masterbatch itself and the moisture on the surface are taken away by the flowing air, thereby achieving the effect of cooling and drying the masterbatch, solving the problems of long processing time and large floor space occupied by general cooling and drying devices. At the same time, the cooled and dried masterbatch can be directly placed in the tank body 10 for storage, saving operating procedures.

[0050] like Figure 1 As shown, it also includes a frame 20, and the external fixed sleeve of the tank body 10 is provided with a support plate 14, and the support plate 14 is connected to the vertical section of the frame 20; the setting of the frame 20 supports the tank body 10.

[0051] like Figure 2As shown, the buffer mechanism 30 also includes a cylinder 32, a spiral plate 31 connected to the side wall of the cylinder 32, and spirally extending upward with the cylinder 32 as the center, and a through hole is provided on the spiral plate 31; the setting of the through hole allows the buffer chamber 11 and the mixing chamber 12 to be connected with the outside, which is beneficial to the air flow inside the tank body 10 and improves the cooling and drying effects. At the same time, when the spiral plate 31 moves, part of the masterbatch falls from the through hole, which is beneficial to the mixing of the masterbatch.

[0052] like Figure 2 As shown, the mixing mechanism 40 also includes a motor 41 connected to the transverse section of the frame 20. The motor 41 provides power for the rotation of the stirring blade 43. The output end of the motor 41 is connected to a stirring shaft 42. The movable end of the stirring shaft 42 passes through the barrel 32 and is connected to the stirring blade 43. When the motor 41 is turned on, the stirring shaft 42 drives the stirring blade 43 to rotate, thereby breaking up the falling masterbatch. The arrangement of the stirring shaft 42 passing through the barrel 32 makes the distribution of the buffer mechanism 30 and the mixing mechanism 40 more reasonable, so that they do not affect each other during operation.

[0053] like Figure 1 、 Figure 3 As shown, the blowing assembly 51 includes a tube body 512 arranged inside the tank body 10, and an air hole is opened on the tube body 512. The two ends of the tube body 512 are respectively fixed through the side wall of the tank body 10 and extend to the outside of the tank body 10. The two ends of the tube body 512 are provided with an exhaust fan 511, and the exhaust fan 511 is installed on the support plate 14 and is connected to the air outlet of the exhaust fan 511. When the exhaust fan 511 is started, air is blown into the storage cavity 13 through the tube body 512.

[0054] The blowing assembly 51 is arranged at the bottom of the storage cavity 13. When blowing air into the tank body 10, the master particles are lifted up, the gaps between the master particles are increased, and the cooling, drying and dust removal operations on the master particles are more convenient.

[0055] The suction component 52 includes a second tube body 521 connected to the side wall of the tank body 10, and a second exhaust fan 522 is provided on the second tube body 521. When the second exhaust fan 522 is started, air is sucked out to the outside of the tank body 10 through the second tube body 521. During the air extraction process, the wind force is set so as not to suck out the masterbatch. A dust bag 523 is provided at the movable end of the second tube body 521 to filter the impurities extracted by the suction component 52. A filter net 524 is provided at the through hole of the second tube body 521 on the side wall of the tank body 10 to prevent the masterbatch from entering the interior of the second tube body 521.

[0056] The blowing assembly 51 blows air into the tank body 10, and the suction assembly 52 draws air out of the tank body 10, so that the air inside the tank body 10 is in a flowing state. The direction of gas flow is as follows: Figure 1As shown by the arrows in the figure, the air flow takes away the heat and surface moisture of the masterbatch, and also takes away the impurities in the masterbatch, thereby removing dust from the masterbatch. The impurities are masterbatch debris formed during the shearing process of the masterbatch, and dust on the surface of the masterbatch during the transportation process.

[0057] Example 2

[0058] Extended from Example 1, the difference from Example 1 is that, Figure 4 As shown, the stirring blade 43 extends downward to the interior of the storage chamber 13; the rotating stirring blade 43, the part inside the mixing chamber 12 breaks up the fallen masterbatch, thereby increasing the degree of diffusion of the masterbatch, and the part inside the storage chamber 13 stirs the masterbatch in the storage state, stirs and mixes the masterbatch of different batches, and improves the uniformity of the finished masterbatch; at the same time, it improves the fluidity of the masterbatch, which is beneficial to the cooling and drying of the masterbatch.

[0059] Example 3

[0060] Extended from Example 1, the difference from Example 1 is that, Figure 5 As shown, the masterbatch cooling and drying integrated device further includes a rapping mechanism 60 for rapping the buffer mechanism 30, and the rapping mechanism 60 includes a cylinder 2 61 connected to the inner wall of the cylinder 1 32, and the cylinder 2 61 is arranged parallel to the radial direction of the cylinder 1 32. A rod 62 is movably inserted in the cylinder 2 61, and one end of the rod 62 located outside the cylinder 2 61 is provided with a spring 64 and connected to an armature 63, and both ends of the spring 64 are respectively connected to the cylinder 2 61 and the armature 63;

[0061] The rapping mechanism 60 also includes a shielding shell 65 corresponding to the position of the armature 63. The shielding shell 65 is embedded in the recess provided on the stirring shaft 42. A magnet 66 is provided inside the shielding shell 65. The shielding shell 65 is provided to cover part of the magnet 66 so that the end of the magnet 66 at the opening position of the shielding shell 65 attracts the armature 63, so that the rod body 62 at different positions moves regularly. The magnet 66 is driven by the stirring shaft 42 to rotate to the position of the armature 63, or to rotate away from the position of the armature 63, so that the rod body 62 can reciprocate in the radial direction of the cylinder body 32, such as Figure 5 As shown by the arrow in , the cylinder 32 is vibrated.

[0062] When the stirring shaft 42 rotates, the magnet 66 is driven to rotate synchronously and rotate to the corresponding armature 63. The armature 63 is adsorbed and the rod body 62 is driven to move in the direction of the stirring shaft 42. After turning away from the armature 63, the rod body 62 is driven to move in the direction of the cylinder 32 under the action of the spring 64 until it contacts the cylinder 32. The reciprocating rod body 62 realizes the vibration of the cylinder 32. During the vibration process, the spiral plate 31 is caused to vibrate, which is beneficial to the diffusion of the masterbatch during the movement and at the same time, it is beneficial to the dredging of the through holes on the spiral plate 31.

[0063] Example 4

[0064] Derived from Example 3, the difference from Example 3 is that, Figure 6 As shown, the integrated masterbatch cooling and drying device further includes a lifting mechanism 70. When the masterbatch needs to be lifted, the control valve 2 in the lifting mechanism 70 is opened, the feed pump 73 is started, and the masterbatch located at the lower part of the storage chamber 13 is re-added from the upper part of the tank body 10.

[0065] The lifting mechanism 70 includes a discharge pipe 71 connected to the discharge port of the tank body 10 and a support plate 2 74 fixedly sleeved on the upper part of the tank body 10. A control valve 1 is provided on the discharge pipe 71. When the masterbatch needs to be taken out of the tank body 10, the control valve 1 is opened. When the masterbatch is lifted, the control valve 1 is closed. The discharge pipe 71 is connected to the pipe body 3 72. The movable end of the pipe body 3 72 is sequentially provided with a control valve 2 and a feed pump 73, and then extends into the interior of the tank body 10. The feed pump 73 is installed on the support plate 2 74.

[0066] The lifting mechanism 70 is set to lift the masterbatch located at the lower part of the storage chamber 13 to the upper part of the tank body 10, and then put it into the upper part of the tank body 10 again, mix it with the newly put masterbatch, and then fall into the storage chamber 13. The masterbatch is circulated and put into the storage chamber 13, so that it is in a flowing state before storage, fully in contact with the flowing air, and fully cooled and dried.

[0067] At the same time, the masterbatch is in a state of circulating input and mixed with masterbatches from different batches, which reduces the differentiation between masterbatches and solves the problem that when preparing materials, different batches of raw materials are put into the mixing tank for mixing, resulting in mixing differences and differentiation between the formed masterbatches.

[0068] like Figure 6 As shown, in order to increase the travel path of the masterbatch, the tube body three 72 spirally extends upward with the tank body 10 as the center. In order to facilitate the heat dissipation of the masterbatch inside the tube body three 72 and the masterbatch inside the tank body 10, a gap is set between the tube body three 72 and the tank body 10.

[0069] In the technical solution of the integrated masterbatch cooling and drying device, the buffer mechanism 30 is provided. After the masterbatch enters the tank body 10, the travel path of the masterbatch is extended, and the contact time with the airflow is increased. The mixing mechanism 40 is provided. After the masterbatch slides down the spiral plate 31, it is dispersed by the rotating stirring blades 43, thereby increasing the distribution range of the masterbatch inside the tank body 10 and the contact area with the airflow. The ventilation mechanism is provided to keep the air inside the tank body 10 in a flowing state, taking away the heat of the masterbatch itself and the moisture on the surface. The lifting mechanism 70 is provided to circulate the masterbatch, so that it is in a flowing state before storage and fully in contact with the flowing air.

[0070] By setting up the buffer mechanism 30, the mixing mechanism 40, the ventilation mechanism and the lifting mechanism 70, the masterbatch is cooled and dried during the storage process, thereby solving the problems of long processing time and large floor space occupied by general cooling and drying devices, and at the same time achieving the effect of mixing different batches of masterbatch and removing dust from the masterbatch.

[0071] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
