DETAILED DESCRIPTION

[0025] To describe the technical content, structural features, achieved purpose and effect of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0026] An embodiment of the present application provides an exhaust device for a barrel, which is installed at the exhaust port of the barrel of an extruder and is used to uniformly discharge the gas exhausted in the barrel into a gas collection system.

[0027] like Figure 1-3 As shown, the exhaust device 100 includes an exhaust chamber 1 connected to the exhaust port, an exhaust cover 2 hinged on the exhaust chamber 1 , an exhaust flange 3 detachably mounted on the exhaust chamber 1 , and an exhaust pipe 4 connected to the exhaust flange 3 .

[0028] like Figure 4-6 As shown, the exhaust chamber 1 includes a first end surface 11 , a second end surface 12 opposite to the first end surface 11 , an exhaust passage 13 penetrating the first end surface 11 and the second end surface 12 , and a side exhaust hole 14 opened on the side wall of the exhaust chamber 1 .

[0029] The exhaust channel 13 forms a first through hole 131 on the first end surface 11 and a second through hole 132 on the second end surface 12. The area of ​​the first through hole 131 is smaller than that of the second through hole 132, which effectively reduces the probability of material overflowing from the exhaust port of the barrel.

[0030] The first end surface 11 is connected to the exhaust port of the barrel, so that the first through hole 131 of the exhaust channel 13 is in fluid communication with the exhaust port, and the side exhaust hole 14 is in fluid communication with the exhaust channel 13 from the side of the exhaust channel 13 .

[0031] like Figure 3 As shown, the exhaust cover 2 is hinged on the second end surface 12 to open and close the second through hole 132 of the exhaust channel 13. When the extruder is working, the exhaust cover 2 covers the second end surface 12 to close the second through hole 132 to prevent the gas discharged from the extruder from leaking into the surrounding environment; the exhaust cover 2 can be opened after the extruder is stopped to clean the exhaust channel 13. Figure 3 , 6As shown, there is an included angle α between the second end face 12 and the first end face 11, and the included angle α is 10°-30°. The inclined second end face 12 facilitates operators to open the exhaust cover 2, thereby increasing the convenience of maintenance.

[0032] like Figure 2 As shown, the exhaust cover 2 is also provided with a visual window 21, through which the operator can directly observe the situation in the exhaust chamber 1 from the outside, and can timely discover the material leakage from the exhaust port and control it.

[0033] like Figure 3-6 As shown, the exhaust flange 3 is detachably mounted at the side exhaust hole 14, and the exhaust flange 3 includes a transition hole, which is opposite to and fluidically connected to the side exhaust hole 14. The exhaust flange 3 is connected to the exhaust chamber 1 through a plurality of bolts 5, and the plurality of bolts 5 are sequentially arranged along the circumference of the transition hole to fix the exhaust flange 3 to the outside of the exhaust chamber 1.

[0034] The exhaust pipe 4 is welded to the exhaust flange 3, and the exhaust pipe 4 is fluidically connected to the side exhaust hole 14 through the transition hole of the exhaust flange 3. The gas discharged from the exhaust port enters the exhaust channel 13 of the exhaust chamber 1 through the first through hole 131, and is then transported to the gas collection system through the exhaust pipe 4 connected to the side exhaust hole 14. The exhaust flange 3 is detachably connected to the exhaust chamber 1. When the exhaust pipe 4 is blocked, it only needs to remove the bolts 5 and remove the exhaust flange 3 and the exhaust pipe 4 welded together for cleaning.

[0035] like Figure 4 , 5 As shown, a baffle plate 6 is also provided in the exhaust chamber 1, and the baffle plate 6 extends from the first end face 11 to the second end face 12 in the exhaust channel 13, and there is a spacing between the baffle plate 6 and the second end face 12 for fluid communication between the first through hole 131 and the side exhaust hole 14; the baffle plate 6 blocks between the first through hole 131 and the side exhaust hole 14, preventing the material emerging from the first through hole 131 from directly clogging the side exhaust hole 14, thereby effectively preventing the side exhaust hole 14 from being clogged.

[0036] like Figure 1 , 2 As shown, a barometer 7 for detecting the air pressure in the exhaust pipe 4 is also installed on the exhaust pipe 4. The operator can determine whether the side exhaust hole 14 is blocked based on the detection result displayed by the barometer 7, and can clean the exhaust pipe 4 in time.

[0037] The present application fixes an exhaust flange on the exhaust pipe that can be detachably connected to the exhaust chamber, thereby reducing the difficulty of disassembly and facilitating cleaning and maintenance of the exhaust device.

[0038] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, and the scope of protection required by the present application is defined by the attached claims, description and their equivalents.
