DETAILED DESCRIPTION

[0016] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0017] The utility model provides a molecular sieve tower that is easy to maintain, including an upper tower body 1 and a lower tower body 2, the ends of the upper tower body 1 and the lower tower body 2 are connected with the same set of limiting rings 3, a diverter plate 4 is arranged inside the upper tower body 1 and the lower tower body 2, a plurality of locking balls 5 and a telescopic spring 6 are distributed circumferentially on the diverter plate 4, the locking balls 5 squeeze the upper tower body 1 and the lower tower body 2 to fit the limiting ring 3, the upper tower body 1 and the lower tower body 2 are both provided with a fitting surface corresponding to the locking balls 5, the fitting surface is composed of a group of inclined planes 101 and a circular arc surface 102, an inner fitting surface matching the fitting surface is arranged inside the limiting ring 3, the middle part of the diverter plate 4 extends downward to form an air inlet pipe 7, the air inlet pipe 7 passes through the lower tower body 2, and is rotatably connected to the lower tower body 2. The upper tower body 1 fits the end surface of the lower tower body 2 and is located in the limiting ring 3. In the initial state, the telescopic spring 6 squeezes the locking ball 5, and the locking ball 5 fits with the arc surface 102, thereby squeezing the upper tower body 1 and the lower tower body 2, so that the upper tower body 1 and the lower tower body 2 fit closely with the limit ring 3, and at the same time, the inclined plane 101 in the fitting surface is tangent to the peripheral surface of the diverter plate 4. When in use, after the intake pipe 7 rotates to a certain angle, the locking ball 5 gradually fits with the inclined plane 101 from the arc surface 102, and at the same time, the fitting surface of the upper tower body 1 and the lower tower body 2 is away from the side of the diverter plate 4, so that the upper tower body 1 and the lower tower body 2 can be easily separated.

[0018] The diverter plate 4 is provided with diverter holes 401 distributed in an array along the circumference of the diverter plate 4, and the locking ball 5 and the telescopic spring 6 are arranged in the diverter hole 401. The limiting ring 3 includes a locking opening ring 301 in contact with the upper tower body 1 and the lower tower body 2, a rubber ring 302 adhered to the inside of the locking opening ring 301, and a locking buckle 303 arranged at the opening of the locking opening ring 301. The inner wall shapes of the locking opening ring 301 and the rubber ring 302 correspond to the shape of the fitting surface. The locking buckle 303 can use a buckle or a screw to apply a certain pressure to the locking opening ring 301, and the upper tower body 1 and the lower tower body 2 are locked and connected. The rubber ring 302 fits tightly with the upper tower body 1 and the lower tower body 2 to achieve sealing.

[0019] The air intake pipe 7 passes through the bottom of the lower tower body 2, and a rotary seal is used between the air intake pipe 7 and the lower tower body 2. Multiple groups of air holes 701 are provided on the air intake pipe 7. When the gas enters from the air intake pipe 7, part of the gas is dispersed and circulated through the air holes 701 and transported through the diverter hole 401. The air intake pipe 7 is connected to the lower tower body 2 by a rotary seal, and the rotary seal can use seals of models such as MG1. The locking ball 5 is located in the diverter hole 401, and the air intake pipe 7 is integrated with the diverter plate 4. The air intake pipe 7 extends to the outside of the lower tower body 2, and then the diverter plate 4 can be driven to rotate by rotating the air intake pipe 7 to adjust the contact position of the locking ball 5 with the fitting surface, thereby changing the locking degree of the tower body and the limit ring 3, so as to facilitate the disassembly and maintenance of the upper tower body 1 and the lower tower body 2.

[0020] Orifice plates 8 are installed on the upper and lower surfaces of the diverter hole 401, and the ends of the orifice plates 8 are located inside the diverter plate 4.

After the intake pipe 7 rotates and the telescopic spring 6 is compressed, the locking ball 5 is located at the end of the limiting space. When the orifice plate 8 is flush with the inclined plane 101, the locking ball 5 forms a point contact with the inclined plane 101, and there is a certain distance between the orifice plate 8 and the inclined plane 101.

[0021] Working principle: the ends of the upper tower body 1 and the lower tower body 2 are aligned, and the fitting surfaces are aligned, the locking ball 5 fits with the arc surface 102, the limiting ring 3 is locked by the locking buckle 303, the lower tower body 2 and the inclined plane 101 at the end of the lower tower body 2 are in contact with the side of the diverter plate 4, and under the action of the telescopic spring 6, the locking ball 5 fits tightly with the arc surface 102, and the sealing ring seals the connection between the upper tower body 1 and the lower tower body 2. When the upper tower body 1 and the lower tower body 2 need to be disassembled, the locking buckle 303 is loosened, the connecting pipe between the upper tower body 1 and the lower tower body 2 is disconnected, the air intake pipe 7 is rotated, and the locking ball 5 is rotated from the arc surface 102 to the inclined plane 101. At this time, only the locking ball 5 is in point contact with the inclined plane 101, the limiting ring 3 is loosened, and the connection between the upper tower body 1 and the lower tower body 2 is loosened.
