[0023] The following detailed description of the application in conjunction with the drawings, it is necessary to point out here that the following detailed description is only used to further illustrate the application, and can not be understood as limiting the scope of the application, the skilled person in the art can make some non-essential improvements and adjustments to the application according to the above application content.

[0024] Example 1

[0025] like Figure 1 - Figure 6 As shown, a plastic film extrusion filter can includes a filter can body 1 and an end cap 2 disposed on the upper end of the filter can body 1, and further includes:

[0026] Jacket 3 is installed inside the filter tank body 1. Cooling water is poured into the gap between the jacket 3 and the filter tank body 1 to cool the filter tank body 1.

[0027] Cooling plate 4 is installed inside the filter tank body 1, dividing the filter tank body 1, and further cooling the filter tank body 1 through cooling plate 4.

[0028] The cooling plate 4 has a cavity inside, and a baffle plate 43 is installed inside the cavity. The end cap 2 is provided with a first water inlet 41 and a first water outlet 42. Both the first water outlet 42 and the first water inlet 41 are connected to the cavity in the cooling plate 4. The cooling plate 4 further cools the filter tank body 1. In conjunction with the jacket 3, it achieves double cooling and better controls the temperature inside the tank. The baffle plate 43 in the cavity and the first water inlet 41 and the first water outlet 42 on the end cap 2 are connected to the cavity in the cooling plate 4, so that the cooling water flows in the cooling plate 4 according to a specific path, which increases the residence time of the cooling water in the cooling plate and improves the cooling efficiency.

[0029] The outer surface of the jacket 3 is provided with a threaded groove 31, which contacts the inner wall of the filter tank body 1. Through holes 32 are provided on both sides of the jacket 3. Cooling water can be poured into the gap between the jacket 3 and the filter tank body 1 to cool the filter tank body 1 through heat exchange. The threaded groove 31 on the outer surface of the jacket 3, which contacts the inner wall of the filter tank body 1, increases the heat exchange area, improves the cooling efficiency, and makes the cooling effect more uniform.

[0030] The filter tank body 1 is provided with a second inlet 5 and a second outlet 6. The second inlet 5 and the second outlet 6 are both connected to the gap between the filter tank body 1 and the jacket 3. A connecting pipe (not shown in the figure) is provided between the first inlet 41 and the second outlet 6. This optimizes the cooling water circulation path, makes the cooling water form a more reasonable circulation in the entire cooling system, improves the overall efficiency of the cooling system, and reduces energy consumption.

[0031] A feed pipe 7 is provided on one side of the filter tank body 1, and a discharge pipe 8 is provided on the other side of the filter tank body 1. The feed pipe 7 and the discharge pipe 8 are located on both sides of the cooling plate 4. Since the cooling plate 4 divides the filter tank body 1 into two areas with the bottom through, when the material enters one area of ​​the filter tank body 1 through the feed pipe 7, it then enters the other area and is discharged through the discharge pipe 8, so that the material can fully contact the cooling plate 4.

[0032] The feeding pipe 7 and the discharging pipe 8 pass through the jacket 3 through the through hole 32 and are connected with the inside of the jacket 3, which ensures that the material is smoothly fed into the jacket 3 for processing.

[0033] It should be noted that when the plastic film extrusion filter tank is working, the plastic raw material enters through the feeding pipe 7 on the filter tank body 1, the feeding pipe 7 and the discharging pipe 8 are connected with the inside of the jacket 3 through the through hole 32 on the jacket 3, which ensures that the material is smoothly fed into the jacket 3. In the inside of the filter tank body 1, the jacket 3 plays an important role, the gap between the jacket 3 and the filter tank body 1 is filled with cooling water, the cooling water flows through the gap, contacts the inner wall of the filter tank body 1 through the threaded groove 31 on the outer surface of the jacket 3, increases the heat exchange area, and preliminarily cools the filter tank body 1. At the same time, the second water inlet 5 and the second water outlet 6 on the filter tank body 1 are connected with the gap of the jacket 3, forming a cooling circulation channel to maintain the cooling effect. The cooling plate 4 is arranged in the filter tank body 1 to further strengthen the cooling, the cavity in the cooling plate 4 is provided with a baffle plate 43, the first water inlet 41 and the first water outlet 42 on the end cover 2 are connected with the cavity in the cooling plate 4, so that the cooling water flows in the cooling plate 4 according to a specific path, improving the cooling efficiency. In addition, the connecting pipe between the first water inlet 41 and the second water outlet 6 optimizes the cooling water flow circulation path. After the plastic completes the filtering process in the filter tank, the filter tank body 1 is divided into two regions through the bottom by the cooling plate 4, so that the plastic can be discharged through the discharging pipe 8. During the whole process, the continuous and effective cooling makes the gas collide with the cooling plate 4 in a low-temperature state in the tank, the oligomers are condensed from gas to solid small molecules, and the oligomers in the cold are intercepted more effectively, so as to avoid the oligomers from entering the vacuum pump and causing the vacuum pump to be damaged.

[0034] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as limiting the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application.
