[0027] The preferred embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0028] In order to facilitate the operation personnel to observe the relevant conditions of the roller, diaphragm and extractant inside the extraction tank 100 during daily inspection, maintenance, operation and accident handling, an observation window is generally installed at the top of the extraction tank 100. However, in actual application, it is easy to close automatically when it is not fully opened, and the observation window may pinch the person during observation, and the safety needs to be improved.

[0029] In view of the above problems, an embodiment of the present application provides a damping observation window for an extraction tank, which can fix the window 1 at various angles through the damping gasket 32 ​​in the damping assembly 3, thereby improving the safety of the extraction tank observation window.

[0030] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0031] See also Figures 1 to 5 , the embodiment of the present application provides a damping observation window for an extraction tank, comprising a window body 1, a connecting seat 2 and a damping component 3;

[0032] The window 11 is disposed on the top cover 200 of the extraction tank 100 and corresponds to the opening of the top cover 200 .

[0033] The first side wall of the window is rotatably connected to the top cover 200 via the connecting seat 2. A plurality of damping components 3 are sleeved on the connecting seat 2. The damping components 3 include stacked gaskets 31 and damping washers 32. The second side wall of the window 1 is detachably connected to the extraction tank 100.

[0034] Specifically, a plurality of damping components 3 are sleeved on the connection seat 2, and are connected to adjacent damping washers 32 through gaskets 31 in the damping components 3. When a group of damping components 3 rotates under force, a plurality of damping components 3 rotate synchronously, and the damping washers 32 in each damping component 3 move relative to the gaskets 31 to generate friction, thereby ensuring that the window 1 can maintain a fixed function at various angles during the opening and closing process. The damping observation window 300 is easy to open and close, greatly facilitating the operator to observe the internal conditions of the extraction tank 100 through the window 1, and effectively improving work efficiency.

[0035] In another embodiment of a damping observation window for an extraction tank provided in an embodiment of the present application, the connecting seat 2 includes a connecting block 21, a fixed shaft 22 and a fixed portion 23, the connecting block 21 is connected and fixed to the extraction tank 100, the fixed shaft 22 is passed through the through hole of the connecting block 21, and a plurality of the damping assemblies 3 are stacked and sleeved on the fixed shaft 22, and the fixed shaft 22 and the fixed portion 23 can rotate relative to each other to squeeze the damping gasket 32.

[0036] Specifically, see Figure 4 and Figure 5 The connection seat 2 can be fixed on the top cover 200 of the extraction tank 100 by welding. During installation, the gasket 31 and the damping gasket 32 ​​are alternately inserted on the fixed shaft 22 in sequence, and then the fixed shaft 22 is locked on the connection block 21 through the fixing portion 23. The end of the fixed shaft 22 facing the fixing portion 23 is provided with a threaded hole corresponding to the fixing portion 23, and the outer periphery of the fixing portion 23 is provided with an external thread. When the damping gasket 32 ​​and the gasket 31 are sleeved on the fixed shaft 22, one end of the fixing portion 23 passes through the through hole on the connection block 21 and aligns with the threaded hole of the fixed shaft 22, thereby locking the fixed shaft 22. When the damping observation window 300 is opened and closed, the gasket 31 and the damping gasket 32 ​​rotate synchronously under the rotation of the window 1, and a corresponding friction force is generated between the gasket 31 and the damping gasket 32, providing a higher friction force to support the window 1 and prevent the window 1 from closing, thereby ensuring the opening and closing fixation at all angles. Several groups of damping components 3 are provided to increase the friction between the connection seat 2 and the window 1, and use the friction to overcome the gravity of the window 1 itself to support the window 1. Exemplarily, the damping washer 32 can be made of nylon material, and the gasket is made of stainless steel plate. Preferably, the thickness of the gasket is 1 to 3 mm, and the thickness of the gasket is 1 to 2 mm.

[0037] In another feasible manner, the two connecting blocks 21 connected to the extraction tank 100 can realize the damping design to be realized in this embodiment by only one rotating shaft. Specifically, threaded holes are opened at both ends of the rotating shaft, through holes of the connecting blocks are passed through both ends of the rotating shaft, and a plurality of damping components 3 are respectively mounted on both ends of the rotating shaft, and the total thickness of the damping components 3 mounted on both ends of the rotating shaft is greater than the length exposed from the end face of the connecting block 21. When the fixing part 23 is screwed into the threaded holes at both ends of the rotating shaft, the gasket and the damping gasket can be pressed by the fixing part 23, thereby realizing the damping design.

[0038] In another embodiment of a damping observation window for an extraction tank provided in an embodiment of the present application, a sealing strip 4 cooperating with the extraction tank 100 is provided on a side of the window body 1 facing the extraction tank 100 .

[0039] In this embodiment, the sealing strip 4 is made of fluororubber with good elasticity, resistance to compression deformation, aging resistance, resistance to dichloromethane corrosion, and a wide operating temperature range (-20°C to 160°C), and is strong and durable. The setting of the sealing strip 4 can effectively close the gap between the extraction tank 100 and the window 1, preventing external dust from entering the extraction tank 100 or dichloromethane in the extraction tank 100 from escaping into the workshop. The setting of the sealing strip 4 can play a good sealing role.

[0040] In another embodiment of a damping observation window for an extraction tank provided in an embodiment of the present application, the window 1 can also be made of plastic material. The window 1 made of plastic material is used, and a dichloromethane-resistant coating is sprayed on the surface of the window 1 to reduce the weight of the overall damping observation window 300. Under this design, 1 or 2 groups of damping components 3 can be used to achieve the damping design of the damping observation window 300, and because the contact between the window 1 and the top cover 200 of the extraction tank 100 is achieved through the sealing strip 4, the plastic window 1 does not produce a direct hard collision with the top cover 200, and the long-term effectiveness of the dichloromethane-resistant coating can be maintained.

[0041] In another embodiment of a damping observation window for an extraction tank provided in an embodiment of the present application, an observation glass window 5 is provided on the window body 1. During the extraction process of the diaphragm, some observation items can be performed through the observation glass window 5, thereby reducing the number of times the damping observation window 300 is opened, avoiding excessive opening and closing, and preventing excessive dichloromethane from escaping from the observation port into the workshop.

[0042] In another embodiment of a damping observation window for an extraction tank provided in an embodiment of the present application, the second side wall of the window body 1 is snap-connected to the extraction tank 100.

[0043] In another embodiment of a damping observation window for an extraction tank provided in an embodiment of the present application, a locking tongue 6 is provided on one side of the second side wall of the window body 1 , and a locking buckle 7 is correspondingly provided on the extraction tank.

[0044] In another embodiment of a damping observation window for an extraction tank provided in an embodiment of the present application, the number of locking tongues 6 is at least two, and the number of the locking buckles 7 is the same as the number of the locking tongues 6 .

[0045] In another embodiment of a damping observation window for an extraction tank provided in an embodiment of the present application, a protective cover 8 is further provided on the second side wall of the window 1, and the protective cover 8 covers the connecting seat 2, and a handle 9 is provided on the first side wall of the window 1.

[0046] In another embodiment of the damping observation window for an extraction tank provided in the embodiment of the present application, the window 1 is made of a stainless steel plate material. Dichloromethane is corrosive to a certain extent, and the window 1 made of a stainless steel plate material can avoid being corroded by dichloromethane, thereby ensuring the long-term applicability of the window 1.

Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
