In order to ensure the stability of the installation of the first sealing ring 21, in this embodiment, please refer to Figure 2 The first sealing ring 21 is sleeved on the second surface 24 and is located at the connection between the second surface 24 and the third surface 25; when installing the gland 2, as the gland 2 is screwed in, the gland 2 moves into the window 11, and the corners of the window 11 can be used to tighten the first sealing ring 21 to achieve a sealed connection between the gland 2 and the window 11.

[0031] In order to facilitate the connection of the gland 2 to the drying cylinder 1, in this embodiment, please refer to Figure 5The end of the gland 2 facing away from the drying cylinder 1 is provided with a first groove 29. There are four first grooves 29, which are evenly distributed along the circumference of the gland 2. During operation, the gland 2 can be rotated by placing a hand or a tool in the first groove 29, making it more convenient to operate the gland 2.

[0032] In other embodiments, the specific form of the pressure cap 2 is not limited to this. For example, the outside of one end of the pressure cap 2 connected to the window 11 is set to a circular structure, and the outside of the other end is set to a square structure, and the width of the square structure is greater than the diameter of the circular structure. During implementation, the circular end of the pressure cap 2 can be used to set a threaded connection to the drying cylinder 1, and the square end can be used to rotate the pressure cap 2, so that the pressure cap 2 can be conveniently screwed to connect the pressure cap 2 to the window 11 of the drying cylinder 1.

[0033] In order to realize the installation of the window glass 3, in this embodiment, please refer to Figure 1 、 Figure 2 and Figure 4 The mounting hole 22 is a stepped hole having a first inner groove surface 26, a second inner groove surface 27 and a third inner groove surface 28. The first inner groove surface 26 and the second inner groove surface 27 are concentrically arranged, and the diameter of the first inner groove surface 26 is smaller than the diameter of the second inner groove surface 27. The third inner groove surface 28 connects the first inner groove surface 26 and the second inner groove surface 27 and is arranged perpendicular to the first inner groove surface 26 and the second inner groove surface 27. A second thread groove threadedly connected to the locking nut 4 is opened on the second inner groove surface 27, so that the pressure cover 2 is threadedly connected to the locking nut 4 through the second inner groove surface 27.

[0040] Working principle: When installing the window glass 3, first place the second sealing ring 31 in the receiving groove of the third inner groove surface 28, then place the window glass 3 in the mounting hole 22, and thread the locking nut 4 into the second threaded groove set on the second inner groove surface 27 until the window glass 3 is pressed tightly, and then thread the pressure cover 2 into the window 11 until the first sealing ring 21 is pressed tightly between the pressure cover 2 and the drying cylinder 1; when removing the window glass 3, first rotate the pressure cover 2 to separate the pressure cover 2 from the window 11 of the drying cylinder 1, and then rotate the locking nut 4 on the other side of the pressure cover 2. After removing the locking nut 4, the window glass 3 can be taken out, which is convenient for replacing and installing the window glass 3.

[0041] The utility model is provided with a drying cylinder 1, a pressure cover 2, a window glass 3 and a locking nut 4. The window glass 3 can be pressed and sealed on the pressure cover 2 by the locking nut 4, and then the pressure cover 2 and the window 11 are connected by a thread to achieve the installation of the window glass 3. The solution adopts a spiral structure to compress the sealing ring, so that the sealing ring is evenly stressed, effectively solving the problem of air leakage of the sealing ring. The spiral structure also realizes the sealed installation of the window glass 3, effectively solving the problem of air leakage and falling off of the window 11 glass. The utility model has the advantages of simple structure, stable installation and easy disassembly.
