[0003] During the conveying and cooling process of finished materials, the cooling method is singular and cannot flexibly select internal and external circulation according to temperature changes, resulting in high energy consumption for cooling.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing a chlorosulfonated film preparation system that enables automated and continuous production of chlorosulfonated films, solves the problem of frequent material feeding by personnel in the laying workshop, and also addresses the issue of high energy consumption during the conveying and cooling process of finished materials.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] A chlorosulfonated film preparation system includes a rotary mixer, a temporary storage bin, a vacuum feeding bin, a weighing bin, an internal mixer, an elevator, an extrusion granulator, a cyclone separator, a dust collector, a vertical vibrating elevator, and a finished product bin arranged sequentially along the process route. The finished product bin is connected to a fully automatic packaging machine at the end.

[0008] An air-cooled hot cutter is installed at the discharge port of the extrusion granulator. A first-stage Venturi accelerator is connected to the bottom of the air-cooled hot cutter. The inlet of the first-stage Venturi accelerator is connected to the release agent adder and the first-stage blower in sequence through pipelines. The outlet of the first-stage Venturi accelerator is connected to the inlet of the cyclone separator through pipelines.

[0009] The vacuum suction chamber is connected in sequence to a vacuum fan, a final dust collector, a plasma box, and an activated carbon adsorption box via pipelines.

[0010] Furthermore, the top air outlet of the cyclone separator is connected to the inlet of the primary fan via a pipeline, and a tee is connected to the end of the pipeline. An air path switching valve a is installed on the side of the tee, and the air path switching valve a is used to control the air input.

[0011] Furthermore, the bottom outlet of the cyclone separator is connected to a secondary venturi accelerator via a pipeline. One end of the secondary venturi accelerator is connected to the outlet of the secondary fan, and the other end of the secondary venturi accelerator is connected to a dust collector via a pipeline.

[0012] Furthermore, the top air outlet of the vertical vibrating elevator is connected to the top air outlet of the finished product warehouse via a tee. The top port of the tee is connected to the inlet of the secondary fan via a pipeline. An air path switching valve c is installed on the pipeline, and a tee is connected to the end of the pipeline.

Detailed Implementation

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] like Figure 1 and Figure 2 As shown in the figure, this utility model provides a chlorosulfonated film preparation system, including a rotary mixer 1, a temporary storage bin 2, a vacuum suction bin 3, a weighing bin 4, an internal mixer 5, an elevator 6, an extrusion granulator 7, a cyclone separator 11, a dust collector 17, a vertical vibrating elevator 18, and a finished product bin 19 arranged sequentially along the process route. The end of the finished product bin 19 is connected to a fully automatic packaging machine.

[0028] The extrusion granulator 7 is equipped with a conical double feeder 8 at its inlet and an air-cooled hot cutter 9 at its outlet. The bottom of the air-cooled hot cutter 9 is connected to a first-stage Venturi accelerator 10. The inlet of the first-stage Venturi accelerator 10 is connected to the release agent adder 12 and the first-stage blower 13 in sequence through pipelines.

[0029] The outlet of the first-stage Venturi accelerator 10 is connected to the inlet of the cyclone separator 11 via a pipeline. The cyclone separator 11 is equipped with a cooling water jacket for primary cooling of the material.

[0030] The top air outlet of the cyclone separator 11 is connected to the inlet of the primary fan 13 via a pipeline. A tee is connected to the end of the pipeline, and an air path switching valve a14 is installed on the side of the tee. The air path switching valve a14 is used to control the air input.

[0031] The bottom outlet of the cyclone separator 11 is connected to the secondary venturi accelerator 15 via a pipeline. One end of the secondary venturi accelerator 15 is connected to the outlet of the secondary fan 16, and the other end of the secondary venturi accelerator 15 is connected to the dust collector 17 via a pipeline.

[0032] The vertical vibrating elevator 18 is a water-cooled enclosed structure with cooling water inlet and outlet at the top for secondary cooling of materials.

[0033] The top air outlet of the vertical vibrating elevator 18 is connected to the top air outlet of the finished product silo 19 via a tee. The top port of the tee is connected to the inlet of the secondary fan 16 via a pipeline. An air path switching valve c25 is installed on the pipeline, and a tee is connected to the end of the pipeline. An air path switching valve b24 is installed on the side of the tee. The air path switching valve b24 is used to control the air input.

[0034] Each of the finished product warehouses 19 is equipped with a cooling water jacket.

[0035] The vacuum suction chamber 3 is connected in sequence to a vacuum fan 20, a final dust collector 21, a plasma box 22, and an activated carbon adsorption box 23 via pipelines.

[0036] The top outlet of the dust separator 17 is connected to the inlet of the final dust collector 21 via a pipeline. The top outlet of the dust separator 17 is also connected to the outlet of the vertical vibrating elevator 18 and the top tee of the finished product silo 19 via a pipeline. The pipeline is equipped with an air path switching valve d26.

[0037] The top outlet of the cyclone separator 11 is connected to the inlet of the final dust collector 21 via a pipeline. An air path switching valve e27 is installed on the pipeline. The pipeline between the cyclone separator 11 and the final dust collector 21 is connected to the pipeline between the finished product silo 19 and the secondary fan 16.

[0038] The bottom of the temporary storage bin 2, the vacuum suction bin 3, and the dust separator 17 are all equipped with rotary unloading valves, and the bottom of the weighing bin 4 is equipped with an unloading butterfly valve.

[0039] The specific working principle of this utility model is as follows:

[0040] Step 1: Use the unpacking machine to put the ton bag of material into the rotary mixer 1. After the material is fully mixed and evenly mixed, it enters the temporary storage bin 2.

[0041] Step 2: The material in the temporary storage bin 2 is automatically conveyed to the weighing bin 4 through the vacuum suction bin 3 for automatic weighing;

[0042] Step 3: Open the bottom discharge butterfly valve of weighing bin 4 to discharge the material into internal mixer 5;

[0043] Step 4: Start the mixing process in the internal mixer 5. After the mixing is completed, discharge the material to the elevator 6.

[0044] Step 5: The elevator 6 conveys the material to the cone double feeder 8, which in turn provides the material to the extrusion granulator 7.

[0045] Step 6: The extrusion granulator 7 performs extrusion granulation, and the air-cooled hot cutter 9 slices the material. The finished sheet material enters the first-stage Venturi accelerator 10. The release agent added by the release agent adder 12 is mixed with the finished sheet by the first-stage fan 13 and conveyed to the cyclone separator 11 for primary cooling. Then it enters the second-stage Venturi accelerator 15 and is conveyed to the dust collector 17. After passing through the rotary discharge valve, it enters the vertical vibrating elevator 18 for long-term secondary cooling. It then enters the finished product silo 19 for temporary storage. The finished product silo 19 is then connected to the packaging machine for packaging.

[0046] In this utility model, the cooling process during the transportation of the finished product from the primary fan 13 to the finished product warehouse 19 involves two methods: internal circulation and external circulation air intake cooling.

[0047] When the air temperature is lower than the top outlet temperature of the vertical vibrating elevator 18 and the finished product silo 19, the secondary fan 16 will circulate externally, opening the air path switching valves d26 and b24 in sequence and closing the air path switching valve c25. The secondary fan 16 will then circulate externally for cooling, which is commonly used in winter when chilled water is not used for auxiliary cooling, thus saving energy. Conversely, when the air temperature is higher, the air path switching valves d26 and b24 will be closed and the air path switching valve c25 will be opened. The secondary fan 16 will then circulate internally for cooling, which is commonly used in summer when the chiller unit is turned on for chilled water cooling mode.

[0048] The switching between internal and external circulation for the primary fan 13 is similar. When the air temperature is lower than the top outlet temperature of the cyclone separator 11, the primary fan 13 will perform external circulation, opening the air path switching valve e27 and air path switching valve a14 in sequence, and closing the air path switching valve d26. This is often used in winter when chilled water is not used for auxiliary cooling, for energy saving. Conversely, when the air temperature is higher, the air path switching valves a14 and e27 will be closed, and the air path switching valve d26 will be opened for internal circulation cooling, which is often used in summer when the chiller unit is turned on for chilled water cooling mode.
