Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of color masterbatch production equipment, specifically relating to a colored material production device. Background Technology
[0002] At the Hostalen ACP production unit, polyethylene wax is a polyethylene byproduct with a relatively lower molecular weight than polyethylene products. In the hexane refining system, the polyethylene wax is separated from hexane and then enters the wax tank in a molten state. For easy collection, a large amount of industrial water is usually added to the wax tank for cooling, causing the molten wax to solidify. After the wax tank reaches a certain temperature, the solidified wax, along with the industrial water, is discharged from the bottom of the wax tank to a wax bag under gravity. The polyethylene wax is collected in pre-prepared wax bags, while the production water is discharged through a drain into a wastewater treatment pond for further processing. The unit has two... The wax tanks are used in two separate ways: one for cooling and solidifying the received molten wax, and the other for receiving melted wax in real time. In the above operations, wax discharge results in a large amount of production water consumption. The production water flows into the ditch and wastewater pond and is collected as production wastewater, further increasing wastewater treatment costs and harming environmental protection. The wax discharge operation also wastes a lot of manpower and resources, increases the workload of operators, and increases the number of wax bags consumed. The polyethylene wax collected in the wax bags needs to be transported downstream for color masterbatch production, which also incurs transportation costs, and there is a possibility that the polyethylene wax will be contaminated during transportation.

[0014] Example 1:
[0015] In one technical solution of this utility model, such as Figure 1As shown, this utility model provides a color masterbatch production device, characterized by including a first pipeline 1 connected to an alkyl refining system for conveying molten polyethylene wax. A flow meter 2 is arranged on the first pipeline 1. One end of the first pipeline 1 branches into a first branch pipeline 3 and a second branch pipeline 4. The first branch pipeline 3 is connected to a first wax tank 6, and the second branch pipeline 4 is connected to a second wax tank 7. Each of the first wax tank 6 and the second wax tank 7 is equipped with a storage tank 24. The first wax tank 6 and the second wax tank 7 are heat-tracing tanks and are stirring tanks. The storage tank 24 is connected to the corresponding first wax tank 6 and the second wax tank 7 via a second pipeline 25. A third ball valve 26 is arranged on the second pipeline 25. A first ball valve 5 is installed on the first branch pipeline 3 and the second branch pipeline 4. The lower part of the first wax tank 6 and the second wax tank 7 is connected to... The first discharge pipeline 8 and the second discharge pipeline 9 are connected to the three-way valve 10. The first wax tank 6 and the second wax tank 7 are equipped with thermometers 11. The three-way valve 10 is connected to the manifold 12. The manifold 12 splits into the third branch pipeline 13 and the fourth branch pipeline 14. The third branch pipeline 13 and the fourth branch pipeline 14 are equipped with second ball valves 19. The third branch pipeline 13 is connected to the first mill 15, and the fourth branch pipeline 14 is connected to the second mill 16. The lower part of the first mill 15 and the second mill 16 is connected to the discharge pipe 17 and the scraper conveyor 20. The first mill 15 and the second mill 16 are equipped with cooling equipment. The discharge pipe 17 is equipped with a rotary discharge valve 27. The scraper conveyor 20 sends the material to the extruder 21. The material extruded by the extruder 21 is weighed by the weighing scale 22 and then sent to the granule silo 23 for storage.
[0016] By adopting the above technical solution, the specific implementation of this solution is as follows: molten polyethylene wax from the alkyl refining system is transported through the first pipeline 1. The branch point of the first pipeline 1 is divided into the first branch pipeline 3 and the second branch pipeline 4 by a multi-port valve. The first ball valve 5 installed on the first branch pipeline 3 and the second branch pipeline 4 keeps the first branch pipeline 3 connected to the first pipeline 1 or the second branch pipeline 4 connected to the first pipeline 1. The first branch pipeline 3 and the second branch pipeline 4 do not flow at the same time. The flow meter 2 installed on the first pipeline 1 measures the flow rate of the molten polyethylene wax. In the following example, this implementation uses the first branch pipeline 3 to be connected and the second branch pipeline 4 to be closed for analysis and explanation. When the second branch pipeline is closed and ready for use, the second wax tank 7 and the storage tank used in conjunction with the second wax tank 7 are both ready for use. At the same time, the second ball valve 19 on the third branch pipeline 13 is opened and connected to the manifold 12. At the same time, the second ball valve 19 on the fourth branch pipeline 14 is not opened, so that the loop between the fourth branch pipeline 14 and the manifold 12 is closed.
[0017] According to the flow rate of flow meter 2, the third ball valve 26 on the second pipeline 25 is opened. The pigment, carrier and additive in storage tank 24 are sent to the first wax tank 6 from the second pipeline 25 according to the set ratio. The set ratio standard is selected and set according to the existing standard and the production batch. Molten polyethylene wax is sent to the first wax tank 6 through the first pipeline 1 and the first branch pipeline 3. The pigment, carrier, additive and polyethylene wax entering the first wax tank 6 are uniformly mixed under the action of the stirrer. During the mixing process, the first wax tank can be heated by steam, electric, hot water or hot air.
[0018] After being mixed evenly, the molten material enters the first mill 15 through the first discharge pipeline 8, three-way valve 10, manifold 12 and third branch pipeline 13 under the action of gravity. The first mill 15 is cooled by a fan during operation to control the solidification rate of the molten material.
[0019] The powder processed by the first mill 15 is conveyed to the extruder 21 by the scraper conveyor 20. The extruder 21 granulates the powder, and the extruded masterbatch granules are weighed and sent to the granule silo 23 for storage.
[0020] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
