Description

Technical Field

[0001] The utility model relates to the technical field of waste gas absorption devices, in particular to a waste gas absorption device for pharmaceutical intermediates. Background Art

[0002] The patent document with application number 202220924932.5 discloses a pharmaceutical intermediate waste gas absorption device, whose working principle is as follows: the waste gas is sucked into the interior of the waste gas treatment box through an air suction pump and the waste gas is guided to the waste gas treatment bracket through the power of the air suction pump, and the servo motor output power is controlled to drive the rotating shaft to rotate, so that the rotating shaft drives the waste gas treatment bracket to rotate, and the waste gas treatment bracket drives the activated carbon adsorption plate and the acid-base neutralization plate inside it to rotate, so that the activated carbon adsorption plate and the acid-base neutralization plate adsorb and neutralize the waste gas entering the waste gas treatment box, and the waste gas is stirred by the rotating waste gas treatment bracket to increase the contact area between the waste gas and the activated carbon adsorption plate and the acid-base neutralization plate.

[0003] According to the attached drawings, the waste gas treatment bracket is a cross structure and can rotate. The rotating waste gas treatment bracket stirs the waste gas to increase the contact area between the waste gas and the activated carbon adsorption plate and the acid-base neutralization plate, thereby effectively improving the efficiency of waste gas absorption treatment and improving the convenience of using the waste gas absorption device.

[0004] However, in actual use, there will inevitably be some exhaust gas between the two brackets that moves with the brackets. These exhaust gases move relative to the brackets, and it takes a long time to come into contact with the filter structure. Moreover, this method is also inconvenient when replacing the filter structure in the bracket, and the bracket needs to be removed, which is not fast enough.

[0005] In response to the above problems, we have launched a pharmaceutical intermediate waste gas absorption device. Utility Model Content

[0012] In a preferred solution, the bottom of the pump is fixedly connected to a bottom plate, the top of the bottom plate and one side of the pump is fixedly connected to a sleeve, and the interior of the sleeve is movably connected to a screw rod.

[0013] By setting up the screw rod, the sleeve can move up and down, and the bottom plate can make the device have a certain degree of expansibility. For example, installing rollers can make the device have a moving effect, etc., which does not belong to the protection scope of this application and is not shown and described.

[0014] In a preferred solution, a keyway is provided on the screw rod, and a flat key for use with the keyway is provided inside the sleeve.

[0015] Through such an arrangement, the screw rod can be limited so that it can only move up and down but cannot rotate.
