Problems solved by technology

[0005]1. The above-mentioned waste gas collection and purification unit is still not comprehensive enough to collect pharmaceutical waste gas, and the wind force generated during the swing process is also limited, so it is difficult to effectively increase the air flow speed ;
[0006]2. The waste gas collection and purification unit mentioned above cannot use the purification particles to adsorb and purify pharmaceutical waste gas. Even if the waste gas collection and purification unit is filled with purification particles, the filled purification particles will The contact effect between exhaust gases is also limited, and it will also increase the wind resistance of the fan, which requires higher wind pressure of the fan and consumes more power;
[0007]3. Although the dust filter suction rack in the above-mentioned exhaust gas collection and purification unit can filter the dust and other particles in the pharmaceutical exhaust gas, it is not convenient to clean the dust adhered to the filter net. Particles are easy to clog the filter screen after a long time of use, and to obtain a better filtering effect, you must use a filter screen with a smaller pore size, but the filter screen with a smaller pore size is more likely to be clogged. The practicability of the suction bracket is poor;

Embodiment 1

[0056] see figure 1 , a pharmaceutical waste gas collection device, comprising a mounting plate 1, one end of the mounting plate 1 is fixedly installed with a side plate 2, and the outer wall of the side plate 2 facing the side of the mounting plate 1 is connected with an air duct 4 through a supporting bearing 3, and the side plate 2. A motor 5 is fixedly installed on the outer wall of the side facing away from the installation plate 1, and the driving device connected between the top of the output shaft of the motor 5 and the air cylinder 4 drives the air cylinder 4 to rotate;

[0057] Several air inlet pipes 8 are fixedly installed on the outer wall on the left side of the air cylinder 4, a negative pressure fan 9 is fixedly installed on the inner wall of the air cylinder 4, an air outlet pipe 10 is fixedly installed on the right end of the air cylinder 4, and the end of the air outlet pipe 10 Extend through the supporting bearing 3 and the side plate 2 to the right side of...

Embodiment 2

[0061] see figure 2 and image 3 , on the basis of Embodiment 1, the inner wall of the air duct 4 is also fixedly installed with a first barrier net 11 and a second barrier net 12, and the first barrier net 11 and the second barrier net 12 are arranged on the left side of the negative pressure fan 9 , the gap between the first barrier net 11 and the second barrier net 12 is filled with purification particles 13;

[0062] When the blower 4 rotates, the purification particles 13 filled between the first barrier net 11 and the second barrier net 12 roll back and forth between the first barrier net 11 and the second barrier net 12, thereby increasing the concentration of the purification particles 13 and the waste gas. The contact area between them has a better adsorption and purification effect on exhaust gas. In this embodiment, the purification particles 13 can be selected as adsorbents with adsorption functions such as activated carbon;

[0063] An elastic sleeve 14 is also...

Embodiment 3

[0067] see Figure 4-Figure 11 , on the basis of Embodiment 1 and Embodiment 2, the air inlet pipe 8 includes an inner cylinder 15, an outer cylinder 16 and a wind deflector 17, the inner cylinder 15 is fixedly installed on the outer wall of the air cylinder 4, and the outer cylinder 16 is sleeved on the On the top of the inner cylinder 15, the wind deflector 17 is fixedly installed on both sides of the top of the outer cylinder 16.

[0068] The top of the inner cylinder 15 is fixed with an inner box 19, the inner box 19 is slidably arranged on the inner wall of the limiting groove 20, the limiting groove 20 is opened on the inner wall of the outer cylinder 16, and the top of the inner box 19 is provided with a ventilation groove 21. A filter screen 22 is arranged inside the box 19, and the filter screen 22 can filter particulate matter in the exhaust gas;

[0069] Both sides of filter screen 22 tops are fixedly equipped with pillars 24, and the top of pillars 24 passes throu...

Abstract

The invention relates to the technical field of pharmaceutical equipment, and discloses a pharmaceutical waste gas collecting device which comprises a mounting plate, a side plate is fixedly mounted at one end of the mounting plate, an air duct is connected to the outer wall of the side, facing the mounting plate, of the side plate through a supporting bearing, and a motor is fixedly mounted on the outer wall of the side, back to the mounting plate, of the side plate. a driving device is connected between the top of the output shaft of the motor and the air duct and drives the air duct to rotate. The motor runs to drive the gear at the top of the output shaft to rotate, the gear rotates to drive the air duct to rotate through the gear ring meshed with the outer wall of the gear, and when the air duct rotates, air can be generated through the air inlet pipe (equivalent to fan blades) fixedly installed on the outer wall of the air duct, so that the air flowing speed in the pharmaceutical workshop can be remarkably increased; when the air duct rotates, the negative pressure fan also operates, air enters the negative pressure fan through the air inlet pipe, and the air inlet pipe rotates and enters the air at the same time, so that the waste gas is collected more comprehensively.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical equipment, in particular to a pharmaceutical waste gas collection device. Background technique [0002] With the improvement of medical level, there are corresponding treatment methods for various diseases, and more and more pharmaceutical workshops are set up. During the normal production and processing of drugs in pharmaceutical workshops, a large amount of chemical waste gas will be generated. These chemical waste gases will not only affect people's health, but also cause serious pollution to the environment. Therefore, how to effectively collect and treat pharmaceutical waste gas is our responsibility. A problem that had to be solved. [0003] The Chinese patent announcement number is: CN108355409B invention patent, which discloses a waste gas collection and purification unit for a pharmaceutical workshop, including a suction swing plate, a sealed air chamber, a burning plate, an exhau...
