Description

Technical Field

[0001] This invention relates to the field of activated carbon adsorption technology for exhaust gas, specifically to a drug detection and treatment device. Background Technology

[0002] In actual drug testing work, it is usually necessary to operate in a laboratory fume hood. The fume hood can ventilate and exhaust drugs in a timely manner after heating and other operations. The exhaust gas from the fume hood usually needs to be heated and carbonized, and then further purified by activated carbon adsorption. Because it is directly related to the exhaust gas emission of drug testing, the quality of activated carbon adsorption is particularly important. Current activated carbon treatment devices for drug testing mainly use fixed activated carbon filter cartridges. With prolonged use, the air inlet of the activated carbon is prone to blockage, increasing air intake resistance and easily causing positive or negative pressure imbalances within the fume hood. This makes it difficult to automatically adjust and compensate for the increased blockage of the activated carbon, affecting the consistency of exhaust gas pressure and making it impossible to pre-determine the activated carbon adsorption compensation area. At the same time, traditional activated carbon treatment devices are prone to leakage of internal exhaust gas and impurities when disassembling and replacing, increasing safety hazards. It is also difficult to seal and protect the activated carbon treatment device during disassembly, increasing safety risks during subsequent transportation. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides a technical solution: such as Figures 1 to 9 The illustrated drug detection and processing device includes an adsorption mounting component 1, with sealing control components 2 installed on both sides of the adsorption mounting component 1 to seal it; an activated carbon adsorption component 3 is installed inside the adsorption mounting component 1; the activated carbon adsorption component 3 is used to adsorb toxic substances in the exhaust gas; a graded isolation component 4 is fixedly installed on the activated carbon adsorption component 3; the graded isolation component 4 is located inside the adsorption mounting component 1; a pressure compensation component 5 is installed on the adsorption mounting component 1, and a one-way limiting component 6 is installed on the pressure compensation component 5; the adsorption mounting component 1 includes: a mounting shell 101 and connecting threads 1011, the mounting shell 101 having a hollow cavity inside; connecting threads 1011 are provided on both sides of the mounting shell 101; flanges are provided at both ends of the mounting shell 101.

[0020] The adsorption mounting component 1 includes: a stop ring 102 and connecting bolts 103. Two stop rings 102 are fixedly sleeved inside the mounting shell 101, and the two stop rings 102 are both annular structures. The inner side of the stop rings 102 is a beveled structure. A ring of connecting bolts 103 is inserted into the flanges at both ends of the mounting shell 101. The mounting shell 101 is used for detecting the exhaust gas of circulating drugs. The sealing control component 2 includes: a sliding shaft 201, a connecting ring 2011, a stop plate 202, and a cover 203. It is slidably mounted on the mounting shell 101. There are four sliding shafts 201, and a connecting ring 2011 is fixedly installed at one end of each of the four sliding shafts 201; a stop plate 202 is fixedly installed at the other end of each of the four sliding shafts 201, and the outer side of the stop plate 202 has a beveled structure, with the stop plate 202 and the stop ring 102 aligned; the stop plate 202 is located inside the mounting housing 101; a cover 203 is rotatably installed on the connecting ring 2011, and the inner side of the cover 203 is threaded into the connecting thread 1011; the cover 203 is fitted onto the flange at the end of the mounting housing 101; the cover...

It can be more suitable for the adsorption of drug detection exhaust gas. The drug residues adsorbed by activated carbon particles 304 are highly toxic and difficult to degrade, and usually need to be transferred and destroyed in a unified manner.

[0021] The activated carbon adsorption component 3 includes: an exhaust plate 301, a front end plate 302, a mesh cylinder 303, and activated carbon particles 304. The exhaust plate 301 is fixedly installed inside the mounting shell 101; the outer ring of the exhaust plate 301 has mesh holes; the front end plate 302 is fixedly installed inside the mounting shell 101, and the front end plate 302 has a through hole in the middle; the mesh cylinder 303 is fixedly installed on the front end plate 302, and the mesh cylinder 303 is fixedly installed on the exhaust plate 301; the mesh cylinder 303 has mesh holes; the mounting shell 101 is filled with activated carbon particles 304, and the activated carbon particles 304 are located between the exhaust plate 301 and the front end plate 302; the activated carbon particles 304 are used to adsorb exhaust gases. Toxic substance; Classified isolation component 4 includes: isolation mounting cylinder 401, separator rings 402, and one-way valves 403. One end of the isolation mounting cylinder 401 is fixedly mounted on the exhaust plate 301, and the other end of the isolation mounting cylinder 401 is fixedly mounted on the front end plate 302. The isolation mounting cylinder 401 is located inside the mesh of the outer ring of the exhaust plate 301. A row of separator rings 402 is fixedly sleeved on the inner side of the isolation mounting cylinder 401, and the row of separator rings 402 is fixedly sleeved on the outer side of the mesh cylinder 303. A one-way valve 403 is fixedly sleeved on each of the row of separator rings 402. The isolation mounting cylinder 401 is filled with activated carbon particles 304. The one-way valve 403 is used for one-way ventilation. Pressure compensation component 5 The system includes: a compensating mounting shaft 501, a spring sleeve 502, a stop sleeve 503, and a compensating spring 504. The compensating mounting shaft 501 is fixedly mounted on the side of the exhaust plate 301; the compensating mounting shaft 501 is located inside the mesh cylinder 303; the spring sleeve 502 is slidably sleeved on the compensating mounting shaft 501, and the stop sleeve 503 is fixedly mounted on the spring sleeve 502, and the stop sleeve 503 is slidably sleeved inside the mesh cylinder 303; the end of the spring sleeve 502 has a beveled structure; one end of the compensating spring 504 is fixedly connected to the exhaust plate 301, and the other end of the compensating spring 504 is fixedly connected to the inside of the spring sleeve 502; the compensating spring 504 is used to elastically support the spring sleeve 502. By employing pressure compensation component 5, as activated carbon particles 304 become saturated and blockage intensifies, this structure can automatically increase the effective air intake area, thereby increasing the effective air intake zone and maintaining stable airflow and ventilation resistance within a reasonable range. This prevents excessively high duct pressure and poor exhaust gas discharge caused by blockage, which could lead to positive or negative pressure imbalances within the fume hood. This structure utilizes a retractable stop cylinder 503 to achieve automatic compensation. Simultaneously, in conjunction with a row of one-way valves 403 on the partition rings 402, it ensures that the activated carbon particles 304 in the compensation area behind the stop cylinder 503 are not used, reserving activated carbon particles 304 to further ensure smooth ventilation, extend service life, and achieve a simple structure.Once the activated carbon granules 304 become highly clogged, the air pressure on the left side of the stop cylinder 503 will increase. This increased air pressure will push the stop cylinder 503 to the right, compressing the compensating spring 504. This compensates for the effective ventilation area of ​​the activated carbon granules 304 on the left side of the stop cylinder 503, maintaining normal ventilation. The structure is simple and reasonable, utilizing the compensating spring 504 to elastically support the spring sleeve 502 for flexible adaptation.

[0022] The pressure compensation component 5 further includes: a ratchet groove 5011, with a row of ratchet grooves 5011 formed on the compensation mounting shaft 501; the one-way limiting component 6 includes: a plug 601, which is slidably inserted into the inner side of the spring sleeve 502, and the inner side of the plug 601 is provided with a ratchet protrusion; the plug 601 is inserted into the ratchet groove 5011; the one-way limiting component 6 further includes: a limiting spring 602, which is provided inside the spring sleeve 502; one end of the limiting spring 602 is fixedly connected to the inner side of the spring sleeve 502, and the other end of the limiting spring 602 is fixedly connected to the plug 601; by using the one-way limiting component 6, one-way limiting of the stop cylinder 50 can be achieved. 3. When the stop cylinder 503 is blocked by activated carbon particles 304, the air pressure increases. After the stop cylinder 503 moves to the right to compensate, it can perform one-way limiting to avoid the stop cylinder 503 resetting distance being too large. This can improve the stability of the stop cylinder 503 and ensure that the range of rightward movement of the stop cylinder 503 is limited when the exhaust gas is introduced. This avoids the range being too large, which would further affect the stability of the exhaust gas emission pressure and also increase the wear of the stop cylinder 503. When the stop cylinder 503 moves to the right due to air pressure, it drives the insert block 601 on the spring sleeve 502 to move together. At this time, the insert block 601 can perform one-way limiting under the elastic push of the limiting spring 602.

[0023] Working principle: Connect the connecting bolt 103 at the left end of the mounting shell 101 to the exhaust pipe of the front-end exhaust gas treatment equipment, and connect the connecting bolt 103 at the right end of the mounting shell 101 to the air inlet pipe of subsequent dust removal equipment. As air enters from the left end of the mounting shell 101, the exhaust gas passes through the mesh cylinder 303, is adsorbed by the activated carbon particles 304, and then, after being adsorbed by the activated carbon particles 304 on the outside of the isolation mounting cylinder 401, is discharged through the mesh holes on the outer ring of the exhaust plate 301, and then exits from the right end of the mounting shell 101 for further treatment. The activated carbon particles 304 near the outer side of the mesh cylinder 303 are more likely to adhere to the exhaust gas. Impurities increase ventilation resistance. When exhaust gas enters the mesh cylinder 303, the activated carbon particles 304 between the partition rings 402 on the left side of the stop cylinder 503 can participate normally in the exhaust gas adsorption. At the same time, the one-way valve 403 can be opened normally without affecting the passage of exhaust gas. However, the one-way valve 403 located on the right side of the stop cylinder 503 will be closed due to the pressure exerted on the left port of the one-way valve 403 by the stop cylinder 503, preventing air from passing through. The activated carbon particles 304 between the partition rings 402 on the right side of the stop cylinder 503 are then sealed and reserved, not participating in adsorption, which facilitates the subsequent operation of the stop cylinder. When 503 moves backward to compensate, the activated carbon particles 304 in the compensated area are not contaminated, ensuring smooth ventilation. If the activated carbon particles 304 become heavily clogged, the air pressure on the left side of the stop cylinder 503 increases. This pressure pushes the stop cylinder 503 to the right, compressing the compensation spring 504 and compensating for the effective ventilation area of ​​the activated carbon particles 304 on the left side of the stop cylinder 503, maintaining normal ventilation. The compensation spring 504 elastically supports the spring sleeve 502, achieving elastic adaptive adjustment of the ventilation area. When the stop cylinder 503 moves to the right due to air pressure, it drives the spring... The insert 601 on the spring sleeve 502 moves together. At this time, the insert 601 can slide normally through the ratchet groove 5011 without getting stuck. However, when the exhaust gas is stopped, the insert 601 is pushed against the compensation mounting shaft 501 by the elastic push of the limit spring 602. The stop cylinder 503 is pushed back to the ratchet groove 5011 adjacent to the insert 601 by the elastic push of the compensation spring 504. The insert 601 will then be inserted into the ratchet groove 5011 for one-way limiting. In this way, when the exhaust gas is introduced again for treatment, the compensation displacement of the elastic retraction of the stop cylinder 503 under the action of the air pressure at the moment of air introduction will not be too large.

[0024] When it is necessary to disassemble the mounting housing 101, because the cover 203 will obstruct the connecting bolt 103, it is impossible to directly insert a wrench. Therefore, it is necessary to first rotate the cover 203 and move it back on the mounting housing 101 until it separates from the connecting thread 1011. At this time, under the elastic push of the closing spring 204, the connecting ring 2011 can be pushed to drive the stop plate 202 to adhere to the stop ring 102, providing sealing protection and preventing leakage. Then, after the operating port 2031 retracts with the cover 203, it connects with the connecting bolt 1011. With the wrench ends aligned, workers can insert the wrench into the operating port 2031 and connect the bolts 103 to complete the disassembly of the mounting shell 101. This prevents workers from missing any sealing steps during operation and ensures the safety of the disassembly and maintenance process. Similarly, when installing a new mounting shell 101, the cover 203 must be manually threaded onto the connecting thread 1011 after the connecting bolts 103 are installed. Only then can the stop plate 202 and the stop ring 102 be separated to allow normal ventilation.
