The grinding device 2 is disposed on the downstream side of the beating and dispersing device 1, and the drying device 3 is disposed on the downstream side of the grinding device 2. The dye post-treatment equipment is particularly suitable for post-treating disperse dyes.

The pulping dispersing device in the prior art adopts a traditional pulping mode, and the dispersing disc is arranged at the top of the pulping pot. Although the stirring shaft of the dispersion disc of the beating dispersion device with the structure is very long, the length of the dispersion disc is not enough to enable the dispersion disc to be close to the bottom of the beating pot, a gap exists between the dispersion disc and the bottom of the beating pot, materials between the dispersion disc and the bottom of the beating pot are difficult to be uniformly stirred, the beating is enabled to have dead angles, and the materials are easily and unevenly stirred. And longer (mixing) shaft leads to dispersion impeller unstable in the making beating process, and the dispersion impeller is easily along with the (mixing) shaft swing, makes energy conversion efficiency lower.

As shown in fig. 1, the beating dispersion device 1 includes a beating pot 11 and a dispersion disc 12, the dispersion disc 12 is rotatably connected to the bottom of the beating pot 11, and the dispersion disc 12 can be rotated by being driven by a motor, so as to stir the material in the beating pot 11. The dispersion disc 12 is close to the bottom surface of the pulping pot 11, so that the materials in the pulping pot 11 can be fully stirred without dead angles.

Further, a flow baffle plate 13 is arranged in the pulping pot 11, and the flow baffle plate 13 can be arranged on the inner wall of the pulping pot 11 along the vertical direction. The flow baffle 13 helps to increase the beating force of the dispersion disc 12, and the materials are rolled downwards when beating, so that the materials in the beating pot 11 can be prevented from splashing, the materials are uniformly dispersed, and the beating efficiency is improved.

The beater 11 is provided with a discharge opening, which may be located, for example, at the bottom of the beater 11. A transfer grooved drum 4 is arranged between the pulping dispersing device 1 and the grinding device 2, a discharge port of the pulping pot 11 is connected with the transfer grooved drum 4 through a pipeline, and materials discharged from the pulping pot 11 can enter the transfer grooved drum 4. The relay chute 4 is provided with a first stirring portion 41, and the material in the relay chute 4 can be prevented from being deposited by the rotation of the first stirring portion 41.

The material is discharged from the discharge gate of making beating pot 11 and gets into buffer slot 14 after the stirring is even in making beating pot 11, and first pump 15 can set up between buffer slot 14 and transit grooved drum 4, can carry the material in the buffer slot 14 to transit grooved drum 4 through first pump 15.

The transfer tank 4 is provided with a discharge port, for example, the discharge port is located at the bottom of the transfer tank 4. The discharge port of the transfer groove drum 4 is connected with the grinding device 2 through a pipeline. A second pump 22 and a flow meter 23 are arranged between the transfer grooved drum 4 and the grinding device 2, the second pump 22 is used for conveying the materials in the transfer grooved drum 4 to the grinding device 2, and the flow meter 23 is used for measuring the total amount of the materials entering the grinding device 2 from the transfer grooved drum 4. When the material is transferred from the transfer chute 4 to the grinding device 2, the flow rate of the material can be measured by the flow meter 23, and the transfer rate of the material can be controlled by controlling the rotation speed of the second pump 22. This allows the total amount of material entering the mill 2 to be adjusted in accordance with the feedback from the flow meter 23. The second pump 22 may be a screw pump and the flow meter 23 may be an electromagnetic flow meter.

In the prior art, materials are pumped into the grinding device and are discharged after being ground, but part of the materials are discharged under the action of a pump without being completely and uniformly ground, so that the grinding efficiency is low and the quality of the prepared dye is uneven. The grinding process is not carried out in a closed environment, so that the material is easy to discharge in an unorganized mode.

As shown in fig. 1, the grinding apparatus 2 of the present invention includes a plurality of grinders 21, for example, 2 to 5 grinders, and 4 grinders 21 are provided in the present embodiment. The specific number of sand mills 21 may be adjusted according to different production requirements, however, an excessive number of sand mills 21 may result in a reduction in grinding efficiency and easily cause clogging of the filter 52. The downstream side of each sander 21 is provided with a third pump 26 for conveying material, and the third pump 26 may be a screw pump.

The sander 21 is closed by means of a mechanical seal, for example the top of the sander 21 is closed by means of a mechanical seal, so that an inorganized discharge of material is prevented.

When the sand mill 21 is grinding, the pressure at the outlet of the sand mill 21 is set to be between 0.02 and 0.1MPa, and the outlet pressure of the sand mill 21 is controlled to achieve sufficient grinding of the material, thereby preventing the material from being discharged out of the sand mill 21 prematurely without being ground.

The sand mill 21 is provided with an inlet and an outlet, a first pressure transmitter 24 is arranged at the inlet of each sand mill 21, a second pressure transmitter 25 is arranged at the outlet of each sand mill 21, and the first pressure transmitter 24 and the second pressure transmitter 25 can be flange type pressure transmitters.

For example, when the entering amount of the material in a certain sand mill 21 exceeds a certain value, the pressure value of the corresponding first pressure transmitter 24 and second pressure transmitter 25 is increased, and then the system can automatically increase the rotation speed of the third pump 26 at the downstream side of the sand mill 21, so that the coarsely ground material is pumped into the next-stage sand mill 21. By analogy, until the pressure at the inlet and at the outlet of each sander 21 stabilizes, the pressure at the outlet reaches the desired set point, for example 0.02 to 0.1 MPa. In addition, when the material is blocked in the sand mill 21, the pressure value of the first pressure transmitter 24 at the inlet of the sand mill 21 is always increased, and the sand mill 21 can automatically stop running when the set safety value is reached, so that accidents are prevented.

It can be understood that the utility model provides a grinder 2 not only can avoid the material unorganized to discharge, and grinder 2 can pass through pressure system automatic control moreover, and the artificial work that has significantly reduced makes sanding efficiency improve, the material homodisperse more after the sanding.

The sander 21 is provided with an abrasive material, such as glass sanding beads, which may be 0.4 mm to 0.6 mm in diameter.

At least one filter 52 is arranged between the milling device 2 and the finished tank 5, for example two filters 52 can be arranged. The upstream side of filter 52 passes through pipe connection transfer grooved drum 4, but the material that does not reach standard through grinding can't pass through filter 52, and the great material of particle size who is sieved by filter 52 returns transfer grooved drum 4 through the pipeline, then grinds through sand mill 21 once more to guarantee the dyestuff quality.

A fourth pump 55, a filter 52 and a material transfer tank 53 are arranged between the finished product tank 5 and the drying device 3, the fourth pump 55 is used for conveying the materials discharged from the finished product tank 5 to the filter 52, and the materials are filtered by the filter 52 and then enter the material transfer tank 53. It will be appreciated that since the material is filtered as it exits the grinding apparatus, only a few impurities of this filtration cannot pass through the filtration, and impurities that do not pass through the filtration can be manually disposed of. The material transfer tank 53 is provided with a liquid level transmitter 53, and a liquid level lower limit and a liquid level upper limit of the material transfer tank 53 are set by a liquid level transmitter 54. When the material reaches the lower level limit of the material transfer tank 53, the fourth pump 55 is turned on to allow the material in the finished product tank 5 to enter the material transfer tank 53, and when the material reaches the upper level limit of the tank, the fourth pump 55 is turned off to stop the material from entering. A fifth pump 56 is arranged between the material transfer tank 53 and the drying device 3, and the fifth pump 56 can convey the material in the material transfer tank 53 to the drying device 3.
