Description
Technical Field
[0001] This invention belongs to the field of waste gas treatment technology, specifically relating to a waste gas treatment device for pharmaceutical production. Background Technology
[0002] Chemical production typically relies on compounds produced by the reaction of various chemicals. These compounds are commonly found in the production of medical drugs and medical experiments. The resulting chemical waste gases also need to be treated using specialized waste gas treatment equipment.
[0003] In the prior art, patent publication number CN220360877U describes a waste gas treatment device for pharmaceutical production. Users of this patent can turn on the blower, heating grid, and intake fan via a switch panel. The intake fan quickly blows the waste gas into the treatment chamber. The blower and heating grid generate high temperatures inside the treatment chamber, killing bacteria in the waste gas. The bacteria-free waste gas then enters the filter chamber, passes through a filter screen and activated carbon adsorber, and is discharged through a connecting ring. After prolonged use, the activated carbon adsorber and filter screen can be pulled out. However, in practical use, the following shortcomings remain: From a practical standpoint, the treatment of waste gas from pharmaceutical production is relatively simple, but replacing the filter is troublesome and requires maintenance shutdowns.
[0004] Therefore, there is a need for a waste gas treatment device for pharmaceutical production to solve the problems existing in the current technology. Utility Model Content
[0005] The purpose of this invention is to provide a waste gas treatment device for pharmaceutical production, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a waste gas treatment device for pharmaceutical production, comprising a primary filter chamber and a secondary filter. The primary filter chamber has a connecting groove on one side, a sliding frame slidably connected to the connecting groove, and several slots on the upper end of the sliding frame, each slot slidably connected to a filter plate. The primary filter chamber has an air inlet on one side and a waste outlet on the lower side. A collection assembly is located below the waste outlet in the primary filter chamber. A communicating vessel is fixedly connected to the middle of one side of the primary filter chamber. The other end of the communicating vessel is installed to the input end of a first air pump via a first connecting pipe. The output end of the first air pump is fixedly connected to a first classifying pipe via a second connecting pipe. Several first connecting pipes are fixedly connected to the other side of the first classifying pipe. Each of the several first connecting pipes is fixedly connected to a secondary filter via a first flange. The other end of each secondary filter is fixedly connected to one end of a second connecting pipe fixedly connected to one side of the second classifying pipe via a second flange. The middle of the other end of the second classifying pipe is installed to the input end of a second air pump via a third connecting pipe. The output end of the second air pump is provided with an air outlet pipe.
[0007] It should be noted in the solution that the collection component includes symmetrical fixing plates, and each of the opposite upper sides of the symmetrical fixing plates is provided with a sliding groove. The sliding grooves are all fitted and slidably connected to the protruding guides fixedly connected to the upper sides of the collection plate.
[0008] It is worth noting that the lower center of the collecting plate is semi-circular.
[0009] Furthermore, it should be noted that a sealing plate is fixedly connected to one side of the sliding frame, and the area of the sealing plate is larger than the cross-sectional area of the connecting groove.
[0010] In a preferred embodiment, each of the filter plates is provided with a plurality of filter holes, and the radius of the filter holes on the filter plates gradually decreases from front to back.
[0011] In a preferred embodiment, each of the secondary filters includes a straight pipe, both ends of which are fixedly connected to connecting flanges, and a filter device is provided in the middle of the straight pipe.
[0012] In a preferred embodiment, the communicating vessel is conical in shape.
[0013] Compared with the prior art, the waste gas treatment device for pharmaceutical production provided by this invention has at least the following beneficial effects:
[0014] (1) Through the primary filtration chamber, the exhaust gas enters the primary filtration chamber through the air inlet and passes through several filter plates, which can filter the impurities in the exhaust gas. At this time, the radius of the filter holes on the filter plates gradually decreases from front to back, which can efficiently filter the impurities in the exhaust gas. At the same time, the filter plates can be loaded, unloaded and cleaned by pulling the sliding frame, thereby increasing the practicality of the exhaust gas treatment device for pharmaceutical production.
[0015] (2) After the exhaust gas is filtered through the primary filter chamber, it enters the first stage pipe, the first connecting pipe and the secondary filter through the second connecting pipe. Then it is filtered by the secondary filter device, which can effectively purify the harmful gases in the exhaust gas to a certain extent, thereby increasing the practicality of the exhaust gas treatment device for pharmaceutical production. Moreover, through multiple secondary filters, it is convenient to disassemble and repair a certain secondary filter. Attached Figure Description

[0021] The present invention will be further described below with reference to embodiments.
[0022] Please see Figure 1-4 This invention provides a waste gas treatment device for pharmaceutical production, comprising: a primary filter chamber 1 and a secondary filter 10. The primary filter chamber 1 has a connecting groove 101 on one side, and a sliding frame 2 is slidably connected to the connecting groove 101. The upper end of the sliding frame 2 has several slots 202, each of which is slidably connected to a filter plate 3. The primary filter chamber 1 has an air inlet 102 on one side, and a waste outlet 103 on one side of the lower end of the primary filter chamber 1. A collection assembly 16 is located below the waste outlet 103 in the primary filter chamber 1. A communicating vessel 4 is fixedly connected to the middle of one side of the primary filter chamber 1, and the other end of the communicating vessel 4 is connected to... The first connecting pipe 5 is installed at the input end of the first air pump 6. The output end of the first air pump 6 is fixedly connected to the first classifying pipe 8 through the second connecting pipe 7. Several first connecting pipes 9 are fixedly connected to the other side of the first classifying pipe 8. Several first connecting pipes 9 are fixedly connected to the secondary filter 10 through the first flange 901. The other end of the secondary filter 10 is fixedly connected to one end of the second connecting pipe 12 fixedly connected to one side of the second classifying pipe 11 through the second flange 13. The middle part of the other end of the second classifying pipe 11 is installed at the input end of the second air pump 15 through the third connecting pipe 14. The output end of the second air pump 15 is provided with an air outlet pipe 17.
[0023] Further as Figure 2As shown, it is worth noting that the collection component 16 includes symmetrical fixing plates 1601. Each of the opposite upper sides of the symmetrical fixing plates 1601 is provided with a sliding groove 1602. The sliding groove 1602 is slidably connected to the protruding guides 1604 fixedly connected to both sides of the upper end of the collection plate 1603. Through the collection component 16, the filtered impurities can be easily removed.
[0024] Further as Figure 2 As shown, it is worth noting that the lower center of the collecting plate 1603 is semi-circular, which facilitates the collection of filtered impurities.
[0025] Further as Figure 2 As shown, it is worth noting that a sealing plate 201 is fixedly connected to one side of the sliding frame 2. The area of the sealing plate 201 is larger than the cross-sectional area of the connecting groove 101. The sealing plate 201 increases the airtightness of the primary filter chamber 1.
[0026] This solution has the following working process: Exhaust gas enters the primary filter chamber 1 through the air inlet 102 and passes through several filter plates 3 to filter impurities in the exhaust gas. At this time, the radius of the filter holes 301 on the filter plates 3 gradually decreases from front to back, which can efficiently filter impurities in the exhaust gas. At the same time, the filter plates 3 can be loaded, unloaded and cleaned by pulling the sliding frame 2. After the exhaust gas passes through the primary filter chamber 1, it enters the communicating vessel 4, the first communicating pipe 5, the first air pump 6, the second communicating pipe 7, the first grading pipe 8, the first connecting pipe 9 and the secondary filter 10. Then it passes through the filtration device 1002 of the secondary filter 10, which can effectively purify the harmful gases in the exhaust gas to a certain extent. After that, it is output through the second connecting pipe 12, the third communicating pipe 14, the second air pump 15 and the exhaust pipe 17. At the same time, it passes through multiple secondary filters 10, which can facilitate the disassembly and maintenance of a certain secondary filter 10.
[0027] As can be seen from the above working process: the collection component 16 can easily remove the filtered impurities; the semi-circular shape at the lower center of the collection plate 1603 can easily collect the filtered impurities; and the sealing plate 201 increases the airtightness of the primary filter chamber 1.
[0028] Further as Figure 2 and Figure 3 As shown, it is worth noting that each of the filter plates 3 is provided with a number of filter holes 301, and the radius of the filter holes 301 on the filter plates 3 gradually decreases from front to back. By the gradual decrease in radius of the filter holes 301 on the filter plates 3 from front to back, impurities in the exhaust gas can be filtered efficiently, thereby increasing the practicality of the exhaust gas treatment device for pharmaceutical production.
[0029] Further as Figure 4 As shown, it is worth noting that each of the secondary filters 10 includes a straight pipe 1001, with connecting flanges 1003 fixedly connected to both ends of the straight pipe 1001, and a filter device 1002 is provided in the middle of the straight pipe 1001. Through multiple secondary filters 10, it is convenient to disassemble and maintain a particular secondary filter 10.
[0030] Further as Figure 1 As shown, it is worth noting that the communicating vessel 4 is conical in shape, which facilitates the connection of exhaust gases.
[0031] In summary: Exhaust gas enters the primary filter chamber 1 through the air inlet 102 and is filtered by several filter plates 3, which remove impurities from the exhaust gas. The filter holes 301 on the filter plates 3 gradually decrease in radius from front to back, efficiently filtering impurities. Simultaneously, the filter plates 3 can be loaded, unloaded, and cleaned by pulling the sliding frame 2. After filtration in the primary filter chamber 1, the exhaust gas then enters the communicating vessel 4, the first communicating pipe 5, the first air pump 6, the second communicating pipe 7, the first grading pipe 8, the first connecting pipe 9, and the secondary filter 10. It is then filtered by the secondary filter 10's filtration device 1002, thus... The system effectively purifies harmful gases in the exhaust gas to a certain extent, and then outputs the gas through the second connecting pipe 12, the third connecting pipe 14, the second air pump 15, and the outlet pipe 17. At the same time, the exhaust gas passes through multiple secondary filters 10, which allows for easy disassembly and maintenance of any one of the secondary filters 10. The filter holes 301 on several filter plates 3 gradually decrease in radius from front to back, which can efficiently filter impurities in the exhaust gas, thereby increasing the practicality of the exhaust gas treatment device for pharmaceutical production. The multiple secondary filters 10 allow for easy disassembly and maintenance of any one of the secondary filters 10. The conical shape of the connecting device 4 facilitates the connection of the exhaust gas.
