Abstract
Description
Technical Field
[0001] This utility model belongs to the field of gas preparation technology, and specifically relates to a toxic gas mixing chamber. Background Technology
[0002] In chemical engineering, scientific research, and other fields, gas mixing chambers are often used to mix various toxic gases in specific proportions. However, existing toxic gas mixing chambers have several problems. For example, after different batches of toxic gases react, the resulting solid or liquid impurities adhere to the inner surface of the chamber. Therefore, after long-term use, impurities easily remain inside the mixing chamber, requiring timely or periodic cleaning. If not cleaned promptly, the residual toxic gases and impurities will affect the gas mixing ratio, interfering with the accuracy of experiments or production processes; even the residual toxic gases and impurities may be corrosive, eroding the internal structure of the mixing chamber and shortening its lifespan. Typically, the cleaning process involves pre-treatment such as multiple gas replacements before cleaning the impurities on the inner wall of the chamber. During cleaning, operators need to take protective measures and directly use cleaning tools to clean the inner wall of the chamber. However, frequent use of tools for deep cleaning is inconvenient. Utility Model Content
[0003] In view of this, the present invention proposes a toxic gas mixing chamber, which can solve the problem of inconvenience in cleaning when using tools for in-depth cleaning.
[0004] This utility model is implemented as follows:
[0005] This utility model provides a toxic gas mixing chamber, which includes a mixing chamber body, a detachable cleaning module, a quick-release gas inlet pipe, a quick-release gas outlet pipe, and a multi-seal structure; the detachable cleaning module is disposed inside the mixing chamber body, and the quick-release gas inlet pipe and the quick-release gas outlet pipe are respectively connected to the mixing chamber body through the multi-seal structure.
[0006] The technical advantages of this utility model for a toxic gas mixing chamber are as follows: By installing a detachable cleaning module inside the mixing chamber body, when cleaning the mixing chamber, the operator only needs to remove the modular cleaning plate from the inner wall of the mixing chamber body through the magnetic connection component for cleaning. This is convenient and quick, effectively preventing residual impurities inside from affecting the gas mixing ratio, thereby ensuring the reliability of experimental data and the stability of product quality. The quick-release gas inlet pipe and quick-release gas outlet pipe are connected to the mixing chamber body through multiple sealing structures, which can significantly improve the sealing performance and prevent toxic gas leakage.

At the same time, the two semi-circular clamps are connected by fastening bolts and clamp the connection to ensure the firmness of the connection.
[0014] Furthermore, the multi-seal structure includes a first sealing layer, a second sealing layer, and a pressure compensation sealing layer; the first sealing layer is a rubber sealing gasket, which is set on the contact surface between the quick-release connector and the main body of the mixing chamber; the second sealing layer is an O-ring, which is set at the insertion part between the pipe body and the main body of the mixing chamber; the pressure compensation sealing layer is an elastic expansion sealing ring, which is sleeved on the outside of the pipe body and tightly fitted to the inner wall of the interface of the main body of the mixing chamber.
[0015] The beneficial effects of adopting the above-mentioned improved scheme are as follows: through the cooperation of the first sealing layer, the second sealing layer and the pressure compensation sealing layer, the rubber sealing gasket of the first sealing layer plays a preliminary sealing role when the quick-release joint is connected to the main body of the mixing chamber, and the O-ring of the second sealing layer further enhances the sealing effect when the pipe is inserted; while the elastic expansion sealing ring of the pressure compensation sealing layer expands and deforms when subjected to internal gas pressure, filling the gaps and achieving dynamic sealing, effectively preventing the leakage of toxic gases.
[0016] Furthermore, the elastic expansion sealing ring is made of memory rubber material, which expands and deforms under pressure to fill the gap between the pipe body and the main interface of the mixing chamber.
[0017] Furthermore, a cover is provided on the top of the gas mixing chamber body, and the cover is connected to the gas mixing chamber body by threads, with a sealing silicone strip at the connection.

[0019] Furthermore, the hatch cover is equipped with a handle and an observation window, the observation window being made of double-layered explosion-proof glass.
[0020] The beneficial effects of adopting the above-mentioned improvement scheme are: using double-layer explosion-proof glass not only facilitates observation of the situation inside the warehouse, but also ensures safety.
