Description

Technical Field

[0001] The invention relates to the technical field of metal powder production, and in particular to a dust detection and sampling device for chemical metal powder production. Background Art

[0002] Metal powder / dust refers to tiny solid particles of metals and their compounds that are suspended in the air for a long time. There are many types of metal dust, including but not limited to aluminum, beryllium, tin, iron, antimony, barium, copper, cobalt, nickel, titanium, etc. Metal dust not only pollutes the environment, but also poses a serious threat to workers' health. For example, long-term inhalation may cause damage to workers' respiratory system, skin, etc., and even cause occupational diseases such as pneumoconiosis; aluminum-magnesium alloy and other dusts are flammable and explosive dusts. When the dust cloud reaches a certain concentration, it may cause a dust explosion when encountering an ignition source, causing casualties, which is very dangerous.

[0003] Therefore, as a metal powder production factory, the measurement of metal dust concentration in the production plant must be carried out regularly or monitored online, and the accuracy of metal dust concentration measurement is also particularly important. If the measured concentration is inaccurate, a series of problems will arise. First, it will lead to insufficient safety protection, because the harm of dust to the human body has a lag, so only when the body has problems can the problem be reflected through body monitoring. Secondly, it is easy to misjudge the risk of explosion. For example, in an aluminum powder processing workshop, when the concentration of aluminum powder reaches 35-40g / m 3 When the concentration is too low, the risk of explosion will increase significantly. And the wrong concentration measurement will directly lead to inaccurate risk judgment.

[0004] However, we consider that in the prior art, when measuring dust concentration, the detector is often used to detect the factory environment. However, in the actual measurement process, when the dust concentration inside the factory is locally dispersed, it is difficult for the existing detector to accurately measure the dust concentration. After groping in the actual use process, it is still necessary to detect by total suspended particle sampling. However, there is a step of replacing filter paper in the total suspended particle sampling process. In the process of replacing filter paper, the operator needs to frequently enter the chemical plant. At the same time, because in the prior art, the installation and disassembly of the filter paper are mostly fixed by means of snap-on fixing structure, threaded connection fixing structure or hinge fixing structure. The disassembly and installation steps of these connection methods are relatively cumbersome and require a long time to operate. Due to the particularity of chemical dust, that is, chemical dust is more harmful to the lungs and skin, a longer operation will cause greater harm to the operator. Therefore, in the prior art, the less the operation time of replacing filter paper, the faster the replacement, and the less harm to the operator. Therefore, we designed this device in terms of how to improve replacement efficiency, how to reduce harm to operators, and improve the safety of the sampling process, a sampling device that can quickly and efficiently replace the filter paper of the dust detector. Summary of the invention

[0005] The purpose of the present invention is to provide a dust detection sampling device for chemical metal powder production, which solves the problem of using a detector to directly detect factory buildings in the prior art. This detection instrument is not suitable for factory dust detection with high concentration. There is also a total suspended matter particle sampling method for detection. At the same time, the traditional sampling instrument requires manual replacement of filter paper. Frequent entry of staff into the factory for replacement will affect the health of users, and the replacement rate and stability of the filter paper are insufficient, resulting in low safety.

[0016] Preferably, sliders are fixedly connected to both sides of the two bearing frames, and the sliders are slidably connected to the top of the support plate through sliding grooves.

[0017] The present invention has at least the following beneficial effects:

[0018] When a dust detection sampling device for chemical metal powder production in the present invention is used, the frame and its components are first placed in a factory building to be detected. According to the requirements of the detection sampling, the filter paper sampling of the two groups of bearing frames is one stage, so one of the bearing frames is placed between the top cover and the air pipe, and the other bearing frame is placed on the top of the support plate and on one side of the push plate. The sampler is started to perform constant air absorption sampling. The sampler is started through constant suction and air pipe to suck the dust scattered in the factory building into the bearing frame through the top cover, and the filter paper in the bearing frame is used to carry the dust. The sealing groove and the sealing ring are used to ensure the sealing of the connection between the top cover and the bearing frame, and the sealing gasket is used to ensure the sealing of the bottom of the bearing frame and the top of the air pipe, so as to avoid the entry of additional dust, affect the service life of the sampler, and affect the detection results;

[0019] When it is necessary to replace the filter paper connected to the bearing frame, the hydraulic cylinder can be started to pull the plate to push, so that the first piston can be pulled by the second piston rod, and the second piston can be pushed at the same time. At this time, the hydraulic oil in the second hydraulic pipe can be pulled by the first piston, so that the hydraulic oil in the second hydraulic pipe can move toward the third hydraulic pipe, and then the third piston in the first piston pipe can be pulled, and the top cover can be lifted up by the third piston rod, so that the top cover is separated from the bearing frame, and at the same time, the second piston is pushed by the second piston rod to push the fourth hydraulic pipe and the hydraulic oil in the first hydraulic pipe, so that the two fourth pistons can be pushed, and then the clamping plate can be pushed by the first piston rod. At this time, the bearing frame at the bottom of the top cover can be clamped by the clamping plate, so that when the top cover is separated from the bearing frame, the bearing frame will not be continuously lifted up by the top cover, and then the hydraulic cylinder is started again to pull the pull plate, so that the first piston can be pushed by the second piston rod, and the second piston can be pulled at the same time. At this time, the hydraulic oil in the second hydraulic pipe can be squeezed, so that the fourth piston and The fifth piston pushes, and then the push plate can be pushed. At the same time, the hydraulic oil in the first hydraulic pipe will move together with the fourth piston when the second piston is pulled, so as to move the clamping plate away from the bearing frame. The bearing frame on the top of the support plate is moved by the push plate, and the bearing frame at the bottom of the top cover can be squeezed out. At this time, the extruded bearing frame will be pushed into the collecting frame through the bearing groove and the elastic sleeve. At the same time, when the fifth piston in the second piston tube continues to push the push plate, as one bearing frame is pushed into the collecting frame, the other bearing frame will be pushed to the top of the top cover. At this time, the top cover is also connected with the bearing frame under the drive of the first piston rod, thereby realizing the replacement of the bearing frame. It should be noted that the movement stroke of the top cover is consistent with the movement stroke of the push plate. When the bearing frame on the support plate is pushed to the bottom of the top cover, the top cover just moves down to the top of the bearing frame and connects with the bearing frame. The present invention greatly improves the replacement rate of the filter paper together with the bearing frame, avoids the time-consuming, labor-intensive and unsafe problem that the staff needs to frequently enter the factory to replace the filter paper, thereby improving the safety of dust sampling and detection in the factory.

[0020] The present invention also has the following beneficial effects:

[0021] 1. By using the flexible nano material film set on the top of the bearing frame, the bearing frame can be used to drive the ventilation pipe to move down when the top cover moves down, and the flexible nano material film can be punctured, so that the air holes on the ventilation pipe can collect dust, and then the dust required for sampling in the factory can be smoothly entered into the bearing frame. The most critical role of the setting of the flexible nano material film is that after the sampling of the bearing frame is completed, the top of the bearing frame can be sealed with the flexible nano material film to prevent dust other than that required for sampling from entering the bearing frame, thereby improving the accuracy of the sampling of the bearing frame. Among them, after the ventilation pipe is separated from the flexible nano material film, the flexible nano material film will use its own characteristics to make the punctured part automatically retract.

[0022] 2. The top of the top cover is elastically connected to the bottom of the first connecting plate through several first tension springs, one side of the two clamping plates are elastically connected to the two second connecting plates respectively through the second tension springs, and both sides of the third connecting plate are elastically connected to one side of the push plate through the third tension spring. This allows the top cover, the clamping plate and the push plate to retract smoothly, thereby avoiding the phenomenon that the top cover, the clamping plate and the push plate cannot be pulled smoothly due to insufficient retraction force of the hydraulic oil in the first hydraulic pipe and the second hydraulic pipe, thereby improving the flexibility of equipment use.

[0023] 3. The fixing ring is connected to the top cover through the protrusion, so that the dust in the factory can enter the bearing frame smoothly without delaying the connection between the top cover and the bearing frame. At the same time, the sliders on both sides of the bearing frame are used to slide on the top of the support plate, so as to ensure the stability of the bearing frame during the process of being pushed by the push plate, prevent the bearing frame from deviating, and improve the stability of the bearing frame movement.

[0045] First, place the frame 1 and its components in the factory building to be tested. According to the requirements of the test sampling, the sampling of the filter paper 44 of the two groups of supporting frames 3 is one stage, and two samples are divided into one group, which is convenient for the subsequent laboratory weighing and comparison of the filter paper 44 samples. Therefore, one of the supporting frames 3 is placed between the top cover 4 and the air pipe 38, and the other supporting frame 3 is placed on the top of the support plate 30 and on one side of the push plate 35. The sampler 2 is started to perform constant air absorption sampling. The sampler 2 is started through constant suction and the air pipe 38 to suck the dust scattered in the factory building into the supporting frame 3 through the top cover 4, and the filter paper 44 in the supporting frame 3 is used to carry the dust. The sealing groove 37 and the sealing ring 47 are used to ensure the sealing of the connection between the top cover 4 and the supporting frame 3, and the sealing gasket 43 is used to ensure the sealing of the bottom of the supporting frame 3 and the top of the air pipe 38, so as to avoid the entry of additional dust, which will affect the service life of the sampler 2 and the test results.

[0046] When it is necessary to replace the filter paper 44 connected to the carrier frame 3, the hydraulic cylinder 17 is started to push the push plate 35, so that the first piston 27 can be pulled by the second piston rod 16, and the second piston 28 can be pushed at the same time. At this time, the hydraulic oil in the second hydraulic pipe 14 can be pulled by the first piston 27, so that the hydraulic oil in the second hydraulic pipe 14 can move toward the third hydraulic pipe 15, and then the third piston 31 in the first piston pipe 5 can be pulled, and the top cover 4 can be lifted up by the third piston rod 32, so that the top cover 4 is separated from the carrier frame 3, and the second piston 28 can be pushed by the second piston rod 16 to separate the top cover 4 from the carrier frame 3. The hydraulic oil in the fourth hydraulic pipe 19 and the first hydraulic pipe 10 is pushed, so that the two fourth pistons 33 can be pushed, and then the clamping plate 22 can be pushed by the first piston rod 34. At this time, the bearing frame 3 at the bottom of the top cover 4 can be clamped by the clamping plate 22, so that when the top cover 4 is separated from the bearing frame 3, the bearing frame 3 will not be continuously lifted by the top cover 4. Then, the hydraulic cylinder 17 is started again to pull the pull plate 18, so that the first piston 27 can be pushed by the second piston rod 16, and the second piston 28 can be pulled at the same time. At this time, the hydraulic oil in the second hydraulic pipe 14 can be squeezed, so that the fourth piston 3 3 and the fifth piston 45 push, and then the push plate 35 can be pushed. At the same time, when the second piston 28 is pulled, the hydraulic oil in the first hydraulic pipe 10 will move together with the fourth piston 33 to move the clamping plate 22 away from the bearing frame 3. The bearing frame 3 on the top of the support plate 30 is moved by the push plate 35, and the bearing frame 3 at the bottom of the top cover 4 can be squeezed out. At this time, the extruded bearing frame 3 will be pushed into the collection frame 24 through the bearing groove 29 and the elastic sleeve 9. At the same time, when the fifth piston 45 in the second piston tube 13 continues to push the push plate 35, as one bearing frame 3 is pushed into the collection frame 24, the other bearing frame 3 will be pushed out. When the support frame 3 is lifted up, the top cover 4 is moved to the top of the top cover 4. At this time, the top cover 4 is also connected with the supporting frame 3 driven by the first piston rod 34, thereby realizing the replacement of the supporting frame 3. It should be noted that the movement stroke of the top cover 4 is consistent with the movement stroke of the push plate 35. When the supporting frame 3 on the support plate 30 is pushed to the bottom of the top cover 4, the top cover 4 just moves down to the top of the supporting frame 3 and connects with the supporting frame 3. The present invention greatly improves the replacement rate of the filter paper 44 together with the supporting frame 3, avoids the time-consuming, labor-intensive and unsafe problem that the staff need to frequently enter the factory to replace the filter paper 44, and improves the safety of dust sampling and detection in the factory.

[0049] By utilizing the flexible nano material film 36 provided at the top of the supporting frame 3, the supporting frame 3 can drive the ventilation pipe 40 to move downward when the top cover 4 moves downward during use, and the flexible nano material film 36 can be punctured, so that the air holes 41 on the ventilation pipe 40 can collect dust and enter, thereby allowing the dust required for sampling in the factory to smoothly enter the supporting frame 3. The most critical role of the setting of the flexible nano material film 36 is that after the sampling of the supporting frame 3 is completed, the flexible nano material film 36 can be used to seal the top of the supporting frame 3 to prevent dust other than that required for sampling from entering the supporting frame 3, thereby improving the sampling accuracy of the supporting frame 3. After the ventilation pipe 40 is separated from the flexible nano material film 36, the flexible nano material film 36 will utilize the characteristics of the flexible nano material film 36 itself to automatically retract the punctured part.

This allows the top cover 4, the clamping plates 22, and the push plate 35 to retract smoothly, thereby avoiding the phenomenon that the top cover 4, the clamping plates 22, and the push plate 35 cannot be pulled smoothly due to insufficient retraction force of the hydraulic oil in the first hydraulic pipe 10 and the second hydraulic pipe 14, thereby improving the flexibility of use of the equipment.
