DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The purification device for tail gas recovery in drug analysis experiments provides two technical solutions:

[0024] like Figure 1 The first embodiment is shown: comprising a suction fan 1 and a purification box 2, a connection mechanism is provided on the right side of the purification box 2, and the connection mechanism comprises:

[0025] The sorting and retrieving component 3 includes two front and rear baffles 31, both of which are fixedly connected to the right side of the purification box 2, a winding drum 32 is rotatably connected between the opposite sides of the two baffles 31, and a hose 33 is wrapped around the surface of the winding drum 32, a handle 34 is rotatably connected to the front of the front baffle 31, and the handle 34 passes through one end of the baffle 31 and is fixedly connected to the winding drum 32, a connecting pipe 5 is connected to the right side of the purification box 2, and a swivel joint is provided on the back side of the rear baffle 31, the other end of the connecting pipe 5 is connected to the swivel joint, and the swivel joint is connected to the hose 33.

[0026] A sorting and recycling component 3 is provided on the device to control the length of the hose 33. When in use, the hose 33 of a suitable length can be pulled out, thereby avoiding the hose 33 being scattered in the laboratory. When not in use, the hose 33 can be separated from the vacuum blower 1 and then recovered separately, thereby solving the problem of having nowhere to put the hose 33 and improving the practicability of the device when in use.

[0027] like Figure 1-3 A second embodiment is shown, and its main difference from the first embodiment is that a connector assembly 4 is arranged at the end of the hose 33, and is used for quick connection between the hose 33 and the connector assembly 4. The connector assembly 4 includes a first T-connector 41 and a second T-connector 42. The first T-connector 41 is rotatably connected to the end of the hose 33, and the second T-connector 42 is fixedly connected to the air outlet of the suction fan 1. A sealing assembly 47 is arranged on the second T-connector 42. Four C-shaped buckle plates 43 are fixedly connected to the annular surface of the first T-connector 41 at equal distances, and four blocks 44 are fixedly connected to the annular surface of the second T-connector 42 at equal distances. A plug 45 is fixedly connected to the right end of the first T-connector 41 for insertion into the interior of the second T-connector 42, and a circular ring platform 46 is fixedly connected to the surface of the first T-connector 41.

[0028] The sealing assembly 47 includes a circular groove 471 opened at the left end of the first T-joint 41, the inner surface of the circular groove 471 is slidably connected with a circular ring 472 through a sliding groove and a slider, a limit spring 473 is fixedly connected between the right side of the inner wall of the circular groove 471 and the side opposite to the circular ring 472, a circular groove 474 is opened on the left side of the circular ring 472, a sealing strip 475 is clamped inside the circular groove 474, the outer diameter of the insert 45 is clearance-matched with the inner diameter of the circular ring 472, and the diameter of the circular ring platform 46 is the same as the diameter of the circular ring 472.

[0029] The hose 33 is connected to the suction fan 1 through the joint assembly 4. When the joint assembly 4 is in use, it only needs to screw on the two T-joints to facilitate the connection between the hose 33 and the suction fan 1. The joint assembly 4 is also provided with a sealing assembly 47 to ensure that no leakage occurs during the experimental exhaust gas transportation. In addition, it also avoids the problem that the connection between the hose 33 and the suction fan 1 is in a bent state for a long time and may break.

[0030] When in use, place the suction fan 1 directly on the experimental table, and toward the experimental operation position, pull the end of the hose 33 equipped with the first T-joint 41, and after the hose is close to the suction fan 1, align the first T-joint 41 with the second T-joint 42, and misalign the C-shaped buckle plate 43 and the stopper 44 during alignment, and insert the insert tube 45 into the second T-joint 42, and insert it into the position where the first T-joint 41 and the second T-joint 42 fit together. After fitting, rotate the first T-joint 41 so that the C-shaped buckle plate 43 is buckled onto the stopper 44. In addition, when the insert tube 45 is inserted into the second T-joint 42, the annular platform 46 contacts the annular ring 472, and pushes the annular ring 472 to move so that the limit spring 473 is compressed, so that the sealing strip 475 is in close contact with the annular platform 46, thereby providing a sealing effect.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
