Description

Technical Field

[0001] This utility model relates to the field of veterinary drug production technology, and in particular to a purification and dust removal device for veterinary drug production. Background Technology

[0002] Veterinary drugs refer to substances (including medicated feed additives) used to prevent, treat, or diagnose animal diseases or to purposefully regulate animal physiological functions. Veterinary drugs mainly include: serum products, vaccines, diagnostic products, microecological products, Chinese medicinal materials, prepared Chinese medicines, chemical drugs, antibiotics, biochemical drugs, radioactive drugs, and external insecticides and disinfectants.

[0003] In the production of veterinary drugs, some ingredients are derived from traditional Chinese medicine. These herbs are often pulverized using a pulverizer. Since traditional Chinese medicine often has strong medicinal properties, the pulverization process generates a large amount of dust and harmful gases. To avoid the dust and harmful gases from harming the working environment and the health of workers, and also to meet environmental protection requirements, it is necessary to collect and treat the dust in the veterinary drug pulverizing room.

[0004] However, existing dust removal devices typically install exhaust fans at the feed hopper and discharge port of the crusher to suck up floating dust, but some dust still diffuses into the production workshop, affecting the working environment. Utility Model Content

[0005] This application discloses a purification and dust removal device for veterinary drug production, which solves the problem that some dust in the prior art diffuses into the production workshop and affects the working environment.

[0006] To solve the above problems, the present invention adopts the following technical solution: A purification and dust removal device for veterinary drug production includes: The grinding chamber is located outside the grinder; Positive pressure fan, located at the top of the crushing chamber; The collection mechanism, located at the bottom of the crushing chamber, is used to collect dust and harmful gases generated during the crushing process. The dust removal and purification unit is located outside the crushing room and is connected to the collection unit through a pipeline. The dust removal and purification unit is used to filter dust and purify harmful gases. The negative pressure fan is connected to the dust removal and purification mechanism through a pipeline. The negative pressure fan is used to maintain negative pressure in the crushing room.

[0007] The technical solution adopted in this utility model can achieve the following beneficial effects: This invention places the pulverizer in a pulverizing chamber, enclosing it to prevent dust from spreading to other areas of the workshop. A negative pressure fan maintains negative pressure inside the pulverizing chamber, while a positive pressure fan, along with a collection mechanism, gathers the dust and harmful gases generated during the pulverizing process and transports them to a dust removal and purification unit. The dust is filtered, and the harmful gases are purified. Finally, the negative pressure fan discharges the purified gas, providing a good working environment for the workers and preventing dust from drifting to the outside. Attached Figure Description

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0012] The terms "first," "second," "third," "fourth," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," "third," "fourth," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0013] The inventive concept of this application is described here: Existing dust removal devices typically install exhaust fans at the feed hopper and discharge port of the crusher to suck up floating dust. However, because the feed hopper is open, a large amount of dust is discharged from the discharge port, inevitably causing some dust to enter the air and affecting the working environment. Moreover, the filter screen is prone to clogging and needs to be removed and cleaned frequently, which reduces production efficiency and is not conducive to practical use.

[0014] Based on this, the inventor provides a purification and dust removal device for veterinary drug production, which isolates the pulverizer to prevent dust from spreading to other areas of the workshop, reducing the impact of dust on the working environment. It can filter dust and purify harmful gases. Furthermore, by vibrating the filter screen, it reduces dust clogging and can better collect dust. It eliminates the need to frequently remove the filter screen for cleaning, thereby improving production efficiency and practicality.

[0015] The following is in conjunction with the appendix Figures 1 to 9 This application provides a detailed description of a purification and dust removal device for veterinary drug production through specific embodiments and application scenarios.

[0016] Reference Figure 1 A purification and dust removal device for veterinary drug production includes: a crushing chamber 100, a positive pressure fan 200, a collection mechanism 300, a dust removal and purification mechanism 400, and a negative pressure fan 500. The grinding chamber 100 is located outside the grinder; Specifically, the crushing chamber 100 is a closed space with an opening on one side. A rubber curtain (not shown in the figure) can be installed at the opening of the crushing chamber 100 to close the crusher and prevent dust from spreading to other areas of the workshop.

[0017] Positive pressure fan 200 is located at the top inside the crushing chamber 100; Specifically, refer to Figure 1 and Figure 2 Multiple positive pressure fans 200 are provided, and their number can be set according to the actual situation. The positive pressure fans 200 are installed on the top of the crushing chamber 100. A dustproof net 210 is provided at the air outlet of the positive pressure fan 200 to prevent dust from affecting the positive pressure fan 200. A through groove 220 is opened in the crushing chamber 100 corresponding to the location of the positive pressure fan 200 to facilitate the air intake of the positive pressure fan 200. The specific structure and working principle of the positive pressure fan 200 are common knowledge, so they will not be described in detail here. The positive pressure fan 200 delivers filtered clean air into the crushing chamber 100. The positive pressure airflow flows from top to bottom, suppressing dust from flying upwards, and forms a directional airflow in conjunction with the negative pressure fan 500.

[0018] The collection mechanism 300 is located at the bottom of the crushing chamber 100 and is used to collect dust and harmful gases generated during the crushing process. Specifically, the collection mechanism 300 utilizes airflow organization and gravity to allow dust to naturally settle into the bottom concentration area, collecting the volatile harmful gases generated during the crushing process and preventing their spread.

[0019] The dust removal and purification mechanism 400 is located outside the crushing chamber 100, and the dust removal and purification mechanism 400 is connected to the collection mechanism 300 through a pipe. The dust removal and purification mechanism 400 is used to filter dust and purify harmful gases. Specifically, the dust is filtered by the dust removal and purification unit 400, and the separated dust (which may contain medicinal powder) can be partially recycled and reused, improving the utilization rate of raw materials, reducing production costs, and purifying harmful gases to ensure that the final emission gas meets environmental protection standards and avoids environmental pollution.

[0020] The negative pressure fan 500 is connected to the dust removal and purification mechanism 400 through a pipe. The negative pressure fan 500 is used to maintain negative pressure inside the crushing room 100.

[0021] Specifically, the negative pressure fan 500 and the dust removal and purification mechanism 400 are connected by a third connecting pipe 800; the specific structure and working principle of the negative pressure fan 500 are common knowledge, so they will not be described in detail here; the negative pressure fan 500 maintains negative pressure inside the crushing chamber 100, and works in conjunction with the positive pressure fan 200 to direct airflow from top to bottom, precisely regulating the pressure inside the crushing chamber 100, ensuring that dust does not escape, and providing a good working environment for the staff.

[0022] Reference Figure 1 In this embodiment, the dust removal and purification mechanism 400 includes a dust removal component 410 and a purification component 420; The dust removal component 410 is connected to the collection mechanism 300 through a pipe, the dust removal component 410 is connected to the purification component 420 through a pipe, and the purification component 420 is connected to the negative pressure fan 500 through a pipe. Specifically, refer to Figure 1 The dust removal component 410 is connected to the collection mechanism 300 through the first connecting pipe 600, the dust removal component 410 is connected to the purification component 420 through the second connecting pipe 700, and the purification component 420 is connected to the negative pressure fan 500 through the third connecting pipe 800.

[0023] The dust removal component 410 is used to filter and collect dust. The separated dust can be partially recycled and reused, thereby improving the utilization rate of raw materials and reducing production costs. Specifically, dust is removed before gas is treated to prevent the adsorbent material in the purification component 420 from being clogged by dust and to extend its service life.

[0024] The purification component 420 is used to adsorb and purify harmful gases, effectively eliminating the irritating odors generated during veterinary drug production, improving the working environment, and ensuring that the emitted gases meet environmental protection standards.

[0025] Reference Figure 1 and Figure 4 In this embodiment, the dust removal assembly 410 includes a dust removal box 411, a filter section 412, a cam section 413, and a reset section 414; The upper part of the dust collection box 411 is connected to the collection mechanism 300 through a pipe, and the lower part of the dust collection box 411 is connected to the purification component 420 through a pipe. Multiple filter sections 412 are provided inside the dust collection box 411. A cam section 413 is provided below the filter section 412 to abut against it, and a reset section 414 is provided above the filter section 412. Specifically, the upper part of the dust collection box 411 is connected to the collection mechanism 300 through a first connecting pipe 600, and the lower part of the dust collection box 411 is connected to the purification component 420 through a second connecting pipe 700. In this embodiment, there are two sets of filter parts 412. Similarly, there are also two sets of cam parts 413 and reset parts 414.

[0026] Reference Figure 6 The dust collector 411 has a rotating dust collector door 4111 on its surface. Every once in a while, the dust collector door 4111 can be opened to remove the filter 412 for cleaning or replacement. The dust collector 411 provides an integrated mounting base for the filter 412, the cam 413 and the reset 414, while forming a sealed space to prevent the leakage of dust-laden gas, ensuring that all dust passes through the filter and improving the overall filtration efficiency.

[0027] The filter section 412 is used to filter dust; Specifically, multiple filter sections 412 intercept dust particles of different sizes, thereby improving the filtration effect.

[0028] The cam portion 413 is used to vibrate the filter portion 412 to prevent the filter portion 412 from becoming clogged; Specifically, the cam 413 vibrates the filter 412, forcing the dust adhering to the pores of the filter 412 to fall off, preventing the dust from spreading everywhere due to the decrease in filtration efficiency. The vibration of the cam 413 also enables automatic dust removal, reducing downtime for workshop maintenance and improving production continuity.

[0029] The reset part 414 is used to reset the filter part 412 so that the filter part 412 is always in contact with the cam part 413.

[0030] Specifically, the filter part 412 is reset by the reset part 414 to avoid dust removal failure caused by the filter part 412 disengaging from the cam part 413, and to prevent structural damage to the filter part 412 due to impact or displacement during vibration, thereby extending the service life of the filter part 412 and ensuring that the filter part 412 is always in contact with the cam part 413.

[0031] Reference Figure 4 In this embodiment, the filter section 412 includes a filter screen 4121, a first connecting plate 4122, and a second connecting plate 4123. The filter screen 4121 is inclined. The higher end of the filter screen 4121 is slidably connected to the first connecting plate 4122, and the lower end of the filter screen 4121 is slidably connected to the second connecting plate 4123. The bottom of the first connecting plate 4122 abuts against the cam part 413. The first connecting plate 4122 is slidably connected to the dust collector 411 through the reset part 414. The second connecting plate 4123 is rotatably connected to the dust collector 411. Specifically, refer to Figure 4 and Figure 5 The higher end of the filter screen 4121 is connected to the first horizontal plate 4124, and the lower end of the filter screen 4121 is connected to the second horizontal plate 4125. The filter screen 4121 is tilted to avoid dust accumulation on its surface, reduce the risk of clogging, and improve filtration efficiency. One end of the first connecting plate 4122 is slidably connected to the dust collection box 411, and the other end of the first connecting plate 4122 has a first slot. The first horizontal plate 4124 can be inserted into the first slot, and the first horizontal plate 4124 and the first slot are slidably engaged. One end of the second connecting plate 4123 is rotatably connected to the dust collection box 411, and the other end of the second connecting plate 4123 has a second slot. The second horizontal plate 4125 can be inserted into the second slot, and the second horizontal plate 4125 and the second slot are slidably engaged.

[0032] Reference Figure 4 The dust collector 411 has a dust outlet 417 at the lower end of the filter screen 4121. One end of the second connecting plate 4123 is located at the bottom of the dust outlet 417, and the second connecting plate 4123 is rotatably connected to both sides of the dust outlet 417. An inclined dust outlet pipe 418 is installed on the dust collector 411 at the dust outlet 417. The end of the dust outlet pipe 418 away from the dust collector 411 is set downward and connected to the dust collection box 419. A second drawer 4191 for collecting dust is installed at the lower part of the dust collection box 419. The dust on the filter screen 4121 can enter the dust collection box 419 for collection under the vibration of the cam part 413. The collected dust is centrally processed by taking out the second drawer 4191. The second drawer 4191 and the dust collection box 419 are sealed together (an elastic sealing strip can be used).

[0033] Filter 4121 is used to filter dust.

[0034] Specifically, the filter screen 4121 swings around the second connecting plate 4123 at a certain angle, making the airflow distribution on the surface of the filter screen 4121 more uniform, eliminating fixed filtration dead angles, reducing the adhesion of dust to the surface of the filter screen 4121, and further improving the dust removal efficiency.

[0035] Reference Figure 4 and Figure 5 In this embodiment, the cam portion 413 includes a second rotating shaft 4131 and a cam 4132; The second rotating shaft 4131 is located below the first connecting plate 4122. A cam 4132 is connected to the second rotating shaft 4131, and the cam 4132 abuts against the bottom of the first connecting plate 4122. Specifically, the second rotating shaft 4131 is horizontally arranged, and both ends of the second rotating shaft 4131 are rotatably connected to the dust collection box 411. Vertically arranged cams 4132 are installed on both ends of the second rotating shaft 4131, that is, two cams 4132 can be set on one second rotating shaft 4131. Reference Figure 4 and Figure 5 In this embodiment, the second rotating shaft 4131 is located at the bottom of the first connecting plate 4122 of the upper filter screen 4121, and the bottom of the first connecting plate 4122 of the lower filter screen 4121 is provided with a third rotating shaft 4133 that is parallel to the second rotating shaft 4131. The two ends of the third rotating shaft 4133 are rotatably connected to the dust collection box 411, and vertically arranged cams 4132 are installed on the two ends of the third rotating shaft 4133.

[0036] The cam 4132 rotates to vibrate the first connecting plate 4122 to prevent the filter screen 4121 from becoming clogged.

[0037] Specifically, by rotating the cam 4132, the first connecting plate 4122 is vibrated, which avoids local blockage caused by the delayed dust removal of the filter screen 4121, improves the filtration efficiency of the filter screen 4121, and achieves automatic dust removal through vibration, reducing downtime for workshop maintenance and improving production continuity.

[0038] Reference Figure 4 and Figure 5 In this embodiment, the reset part 414 includes a slide groove 4141, a guide rod 4142, and an elastic member 4143; A sliding groove 4141 is provided inside the dust collection box 411 corresponding to the first connecting plate 4122. One end of the first connecting plate 4122 is located in the sliding groove 4141, and the first connecting plate 4122 is slidably connected to the sliding groove 4141. Multiple guide rods 4142 that penetrate the first connecting plate 4122 are installed in the sliding groove 4141. The first connecting plate 4122 and the guide rods 4142 are slidably connected. An elastic element 4143 sleeved on the outer surface of the guide rods 4142 is connected between the inner wall of the sliding groove 4141 and the first connecting plate 4122. Specifically, the guide rod 4142 is vertically arranged, and a through hole is provided on the first connecting plate 4122. The guide rod 4142 is located in the through hole. The first connecting plate 4122 is slidably connected to the guide rod 4142 through the through hole, and the diameter of the through hole is larger than the diameter of the guide rod 4142. During the swinging process of the first connecting plate 4122 with the filter screen 4121, the through hole of the first connecting plate 4122 will not interfere with the guide rod 4142, avoiding the problem that the first connecting plate 4122 cannot swing. In addition, the setting of the guide rod 4142 prevents the first connecting plate 4122 from laterally tilting under the vibration impact of the cam 4132, ensuring that the bottom of the first connecting plate 4122 always abuts against the cam 4132. An elastic element 4143 sleeved on the outer surface of the guide rod 4142 is connected between the inner wall of the slide groove 4141 and the top of the first connecting plate 4122. The elastic element 4143 is preferably a spring.

[0039] The first connecting plate 4122 is reset by the elastic element 4143 so that the bottom of the first connecting plate 4122 is always in contact with the cam 4132.

[0040] Specifically, when the cam 4132 rises, it pushes the first connecting plate 4122 upward, and the elastic element 4143 is compressed simultaneously to absorb the impact kinetic energy of the cam 4132, avoiding surface wear caused by hard contact between the first connecting plate 4122 and the cam 4132. When the cam 4132 falls, the elastic potential energy of the elastic element 4143 is released, which drives the first connecting plate 4122 to fall back quickly, ensuring the reset speed and buffering the impact of the fall through the elastic force, thus reducing mechanical noise.

[0041] Reference Figure 4 and Figure 7 In this embodiment, the dust removal assembly 410 further includes a fan blade 415 and a linkage part 416; The fan blade 415 is located at the connection between the collecting mechanism 300 and the dust collection box 411. One end of the linkage part 416 is connected to the fan blade 415, and the other end of the linkage part 416 is connected to the cam part 413. Specifically, the fan blade 415 is rotatably mounted at the connection between the first connecting pipe 600 and the upper part of the dust collection box 411. The fan blade 415 is mounted on the first rotating shaft 4151, which is horizontally set. Both ends of the first rotating shaft 4151 are rotatably connected to the first connecting pipe 600, and one end of the first rotating shaft 4151 extends out of the first connecting pipe 600 and connects to one end of the linkage part 416. The other end of the linkage part 416 is connected to the second rotating shaft 4131 and the third rotating shaft 4133.

[0042] The linkage 416 is used to transmit the power generated by the fan blade 415 to the cam 413.

[0043] Specifically, by the airflow impacting the fan blade 415, the fan blade 415 rotates automatically, providing continuous power to the cam 4132. There is no need to configure an additional drive motor, which simplifies the overall structure of the device, significantly reduces manufacturing costs and energy consumption, and improves the overall reliability and stability of the device operation.

[0044] Reference Figure 4 and Figure 7 In this embodiment, the linkage 416 includes a first synchronous pulley 4161, a second synchronous pulley 4162, and a first synchronous belt 4163; The first synchronous pulley 4161 is connected to the fan blade 415, the second synchronous pulley 4162 is connected to the second rotating shaft 4131, and the first synchronous belt 4163 is wound between the first synchronous pulley 4161 and the second synchronous pulley 4162.

[0045] Specifically, the first synchronous pulley 4161 is connected to the first rotating shaft 4151. The first synchronous pulley 4161 and the second synchronous pulley 4162 are vertically arranged. The first synchronous pulley 4161 and the second synchronous pulley 4162 can be toothed pulleys. The first synchronous belt 4163 can be a toothed belt. The specific structure and working principle of the toothed pulleys and toothed belts are common knowledge, so they will not be described in detail here.

[0046] Reference Figure 7 The linkage unit 416 also includes a third synchronous pulley 4164 connected to the second rotating shaft 4131. One end of the third rotating shaft 4133 extends into a dust collection box 411 and connects to a fourth synchronous pulley 4165. A second synchronous belt 4166 is wound between the third synchronous pulley 4164 and the fourth synchronous pulley 4165. The third synchronous pulley 4164 and the fourth synchronous pulley 4165 are vertically arranged. The third synchronous pulley 4164 and the fourth synchronous pulley 4165 can be toothed pulleys, and the second synchronous belt 4166 can be a toothed belt. The specific structure and working principle of the toothed pulleys and toothed belts are common knowledge, so they will not be described in detail here.

[0047] The rotation of the fan blade 415 drives the first rotating shaft 4151 to rotate, which in turn drives the first synchronous pulley 4161 to rotate. The first synchronous pulley 4161 drives the second synchronous pulley 4162 to rotate via the first synchronous belt 4163, which in turn drives the second rotating shaft 4131 to rotate, which in turn drives the third synchronous pulley 4164 to rotate. The third synchronous pulley 4164 drives the fourth synchronous pulley 4165 to rotate via the second synchronous belt 4166, which in turn drives the third rotating shaft 4133 to rotate, which in turn drives the cam 4132 to rotate. This ensures the synchronicity of the second rotating shaft 4131 and the third rotating shaft 4133, reduces power transmission loss, maintains effective dust removal, and improves dust removal efficiency.

[0048] Reference Figure 8 and Figure 9 In this embodiment, the purification component 420 includes a purification box 421, a first drawer 422, and an activated carbon plate 423; The purification box 421 and the dust removal box 411 are connected by a pipe at the bottom. The purification box 421 is provided with multiple first drawers 422, and the first drawers 422 are provided with activated carbon plates 423. Specifically, refer to Figure 8 The purification box 421 can adopt a fully enclosed structure design. The upper part of the purification box 421 and the lower part of the dust removal box 411 are connected by a second connecting pipe 700. In this embodiment, three first drawers 422 are provided. The first drawers 422 and the purification box 421 are sealed together (elastic sealing strips can be used). The activated carbon plate 423 can be replaced by removing the first drawer 422, making maintenance convenient and quick. The lower part of the purification box 421 is connected to the negative pressure fan 500 through a third connecting pipe 800.

[0049] The bottom of the first drawer 422 has a through hole 424 to facilitate the passage of gas; inside the purification box 421, support blocks 425 are installed on both sides of the bottom of the first drawer 422 to support the first drawer 422.

[0050] Activated carbon plate 423 is used to adsorb and purify harmful gases, and the adsorption efficiency is improved by setting multiple layers.

[0051] Reference Figure 1 , Figure 3 and Figure 4 In this embodiment, the collection mechanism 300 includes a grid 310, a primary filter layer 320, and a sunken collection channel 330; The grid 310 is located at the bottom of the crushing chamber 100. A primary filter layer 320 is located below the grid 310. A sunken collection channel 330 is located below the primary filter layer 320. The sunken collection channel 330 is connected to the upper part of the dust collection box 411 through a pipe. Specifically, the pulverizer can be placed on the grille 310, which is detachable for easy cleaning of impurities and to prevent impurities from accumulating and affecting airflow or causing secondary pollution. The primary filter layer 320 is preferably a V-shaped filter to perform primary filtration of large particles, significantly reducing the processing pressure on the fan blades 415 and the filter screen 4121. The primary filter layer 320 can be installed with a snap-on design, so there is no need to disassemble the sunken collection channel 330 when replacing or cleaning; only the primary filter layer 320 needs to be pulled out. The sunken collection channel 330 is connected to the upper part of the dust collection box 411 through the first connecting pipe 600. The sunken collection channel 330 has a funnel-shaped structure design, which allows dust and harmful gases to settle naturally and converge to the bottom of the channel under the combined action of gravity and airflow, preventing them from spreading or suspending in the pulverizing chamber 100 and improving the aggregation efficiency. The aggregated dust-laden gas flows directionally into the dust collection box 411 along the first connecting pipe 600 without airflow backflow or eddies, reducing secondary dust re-entrainment.

[0052] The primary filter layer 320 is used for primary filtration of large particulate impurities; The sunken collection channel 330 is used to collect dust and harmful gases generated during the crushing process.

[0053] In this embodiment, an electrical control cabinet (not shown) is provided on the outside of the crushing chamber 100; the electrical control cabinet (not shown) contains various electrical components, system programs, operation panels, etc., which control the entire device to perform actions according to the predetermined program, process various sensors and signal sources, output corresponding program instructions, and at the same time, external indicator lights and alarm lights display the device's operating status, and external buttons can pause or stop the device's operation.

[0054] Working Principle: During operation, the positive pressure fan 200 and negative pressure fan 500 are activated to direct airflow from top to bottom, maintaining negative pressure within the crushing chamber 100. Dust particles pass through the grille 310 and primary filter layer 320 into the sinking collection channel 330, where large particles are filtered. The dust-laden gas collected in the sinking collection channel 330 flows directionally into the dust collector 411 along the first connecting pipe 600, where it is filtered through the filter screen 4121. Simultaneously, the airflow impacts the fan blades 415, causing them to rotate automatically. This rotates the first shaft 4151, which in turn rotates the first synchronous pulley 4161. The first synchronous pulley 4161, via the first synchronous belt 4163, drives... The rotation of the second synchronous pulley 4162 drives the rotation of the second rotating shaft 4131, which in turn drives the rotation of the third synchronous pulley 4164. The third synchronous pulley 4164 drives the rotation of the fourth synchronous pulley 4165 via the second synchronous belt 4166, which in turn drives the rotation of the third rotating shaft 4133, which in turn drives the rotation of the cam 4132, causing the first connecting plate 4122 to vibrate, thereby vibrating the filter screen 4121 to prevent the filter screen 4121 from clogging. The gas after dust removal enters the purification box 421 through the second connecting pipe 700, where the activated carbon plate 423 adsorbs and purifies the harmful gases, and the negative pressure fan 500 discharges the qualified gas, providing a good working environment for the staff and preventing the problem of dust drifting to the outside.
