[0020] Embodiment 1

[0021] AsFigures 1 to 4 As shown in the figure, a special cylinder for a hydrogen chloride compressor in the first aspect embodiment of the present utility model includes a cylinder body 1. An air hole 2 is provided on the side of the cylinder body 1. A piston rod 5 is movably sleeved inside the cylinder body 1. An installation plate 4 is fixedly installed at the outer end of the piston rod 5. A protection component 3 is fixedly installed on the inner wall of the installation plate 4. A water absorption hole 101 is provided on the front of the cylinder body 1. A ring groove 102 is provided at the end of the water absorption hole 101. A transmission hole 103 is provided in the middle of the ring groove 102. A water absorption component 6 is fixedly installed above the transmission hole 103 at the top of the cylinder body 1. The protection component 3 includes a sleeve one 301. A sleeve two 302 is movably sleeved inside the sleeve one 301. A sealing gasket 303 is fixedly installed at the end of the sleeve two 302. A connecting block 304 is fixedly installed on the outer wall at the end of the sleeve two 302. The end of the sleeve one 301 is fixedly connected to the outer end of the cylinder body 1. A bolt is threadedly installed inside the connecting block 304. The connecting block 304 fixes the sleeve two 302 and the installation plate 4 through the bolt.

[0022] In the above embodiment, it should be noted that there is a spacer ring between the wall of the ring groove 102 and the piston rod 5, so as to prevent gas from entering from the sliding part of the piston rod 5, and also stabilize the sliding connection of the piston rod 5.

[0023] The technical effect achieved by the above embodiment is that the sealing gasket 303 can effectively seal the connection between the sleeve two 302 and the installation plate 4, prevent hydrogen chloride gas from entering the inside of the protection component 3 and directly contacting the piston rod 5, and achieve the first layer of protection effect.

[0024] Embodiment 2

[0025] As Figure 4 shown, a special cylinder for a hydrogen chloride compressor includes all the contents of Embodiment 1. In addition, the water absorption component 6 includes an installation seat 601. An air pump 602 is fixedly installed inside the installation seat 601. One end of the air pump 602 is fixedly communicated with a one-way pipe 603. A connecting pipe 604 is provided at the bottom end of the one-way pipe 603. A clamping strip 607 is detachably installed inside the installation seat 601. A placing ring 605 is fixedly installed inside the clamping strip 607. Filter plates 606 are provided at both the upper and lower ends of the placing ring 605. The bottom end of the connecting pipe 604 is fixedly communicated above the transmission hole 103. The bottom end of the installation seat 601 is fixedly installed on the top surface of the cylinder body 1. A water absorbent is placed inside the placing ring 605.

[0026] The technical effects achieved by the above embodiments are as follows: The filter plate 606 can effectively store the water absorbent inside the placement ring 605, and then prevent the mounting base 601 from sucking the water absorbent into the one-way tube 603 during operation, ensuring the normal water removal function of the whole. In addition, the clamping strip 607 can effectively clamp the placement ring 605 inside the mounting base 601 to prevent it from shaking due to the vibration of the cylinder body 1 during operation. Finally, the water absorbent is used to remove water in the area formed by the protective component 3 and the piston rod 5, achieving the effect of secondary protection.

[0027] Working principle: The sleeve two 302 is fixedly connected to the mounting plate 4 by bolts through the connecting block 304, and then the sealing gasket 303 is attached to the inner wall of the mounting plate 4 to complete the sealing and fixing. As the piston rod 5 expands and contracts, the sleeve one 301 and the sleeve two 302 are automatically adapted and adjusted. Then, the air pump 602 is started regularly to suck the gas in the space between the sleeve one 301, the sleeve two 302 and the piston rod 5. Then the gas enters the inner part of the annular groove 102 from the water absorption hole 101, passes through the transmission hole 103, passes through the connecting pipe 604 inside the placement ring 605, is absorbed by the water absorbent, and finally is discharged from the one-way tube 603 by the air pump 602 to realize water discharge and prevent the formation of an aqueous solution with hydrogen chloride, achieving the purpose of secondary protection.
