Description

Technical Field

[0001] The present invention relates to the technical field of metal powder production, 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 remain suspended in the air for extended periods of time. Metal dust comes in many different types, including but not limited to aluminum, beryllium, tin, iron, antimony, barium, copper, cobalt, nickel, and titanium.

[0003] Therefore, for metal powder production plants, 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 particularly important. If the measured concentration is inaccurate, a series of problems will arise.

[0004] However, we take into account that in the existing technology, when measuring dust concentration, detectors are 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 detectors to accurately measure the dust concentration. After exploration during actual use, it is still necessary to use the total suspended particle sampling method for detection. However, there is a step of replacing the filter paper in the total suspended particle sampling process. In the process of replacing the filter paper, the operator needs to frequently enter the chemical plant. At the same time, because in the existing technology, the installation and disassembly of the filter paper are mostly fixed by means of a snap-on fixing structure, a threaded connection fixing structure or a hinged fixing structure. The disassembly and installation steps of these connection methods are relatively cumbersome and require a long time to operate. Therefore, we designed this device in terms of how to improve the replacement efficiency, how to reduce the harm to the operator, and improve the safety of the sampling process. It is 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 that the existing technology uses a detector to directly detect the factory building.

At the same time, the traditional sampling instrument requires manual replacement of filter paper. The staff frequently enters the factory to replace it, which will affect the health of the user.

[0016] Preferably, sliders are fixedly connected to both sides of the two supporting 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 the dust detection sampling device for chemical metal powder production of the present invention is used, the frame and its components are first placed in a plant to be detected. According to the requirements of the detection sampling, the filter paper sampling of the two groups of carrier frames is one stage, so one of the carrier frames is placed between the top cover and the air pipe, and the other carrier 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. When the sampler is started, the dust scattered in the plant is sucked into the carrier frame through the top cover through constant suction and the air pipe, and the filter paper in the carrier 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 carrier frame, and the sealing gasket is used to ensure the sealing of the bottom of the carrier frame and the top of the air pipe, so as to avoid the entry of extra dust, which will affect the service life of the sampler and the detection results.

[0019] When it is necessary to replace the filter paper connected to the carrying frame, the hydraulic cylinder is started to pull the plate, 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 carrying frame. 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 splint can be pushed by the first piston rod. At this time, the carrying frame at the bottom of the top cover can be clamped by the splint, so that when the top cover is separated from the carrying frame, the carrying 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 splint away from the load-bearing frame. The load-bearing frame on the top of the support plate is moved by the push plate, and the load-bearing frame at the bottom of the top cover can be squeezed out. At this time, the extruded load-bearing frame will be pushed into the collection frame through the load-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 load-bearing frame is pushed into the collection frame, the other load-bearing frame will be pushed to the top of the top cover. At this time, the top cover is also driven by the first piston rod to dock with the load-bearing frame, thereby realizing the replacement of the load-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 load-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 load-bearing frame and docks with the load-bearing frame. The present invention greatly improves the replacement rate of the filter paper together with the load-bearing frame, avoids the time-consuming, labor-intensive and unsafe problem that the staff need 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] The flexible nanomaterial membrane installed on the top of the carrier frame can be used to drive the ventilation pipe downward when the top cover moves down. The flexible nanomaterial membrane can be punctured, allowing the air holes on the ventilation pipe to collect dust and allow the air sampled in the factory to enter the carrier frame smoothly. The most critical function of the flexible nanomaterial membrane is that after the carrier frame completes sampling, the flexible nanomaterial membrane can be used to seal the top of the carrier frame to prevent dust other than that required for sampling from entering the carrier frame, thereby improving the accuracy of the carrier frame sampling. After the ventilation pipe is separated from the flexible nanomaterial membrane, the punctured part will automatically retract due to its own characteristics.

[0022] 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 is 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, clamping plate and push plate to retract smoothly, thereby avoiding insufficient retraction force of the hydraulic oil in the first hydraulic pipe and the second hydraulic pipe, which will cause the top cover, clamping plate and push plate to be unable to be pulled smoothly, thereby improving the flexibility of equipment use.

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

[0043] Both sides of the supporting frame 3 at the bottom of the top cover 4 are provided with plywood 22, and the opposite sides of the two plywood 22 are rotatably connected to a number of wheel bodies 20, and a first hydraulic pipe 10 is provided on one side of the frame body 1, and the inner sides of both ends of the first hydraulic pipe 10 are provided with fourth pistons 33, wherein one side of the two fourth pistons 33 are fixedly connected to the first piston rod 34, and one end of the two first piston rods 34 is fixedly connected to one side of the two plywood 22 respectively, the middle part of the first hydraulic pipe 10 is connected to the fourth hydraulic pipe 19, and the middle part of the second hydraulic pipe 14 is connected to the third hydraulic pipe 15, the inner side of the third hydraulic pipe 15 is provided with a first piston 27, and the inner side of the fourth hydraulic pipe 19 is provided with a second piston 28, and the second piston rod 16 is fixedly connected between the first piston 27 and the second piston 28, and the middle part of the second piston rod 16 is fixedly connected to Pull plate 18, and one side of the outer wall of the frame 1 is fixedly connected to the hydraulic cylinder 17 by bolts, and the output shaft of the hydraulic cylinder 17 passes through the side wall of the frame 1 and is fixedly connected to one side of the pull plate 18, the inner sides of the first hydraulic pipe 10, the second hydraulic pipe 14, the third hydraulic pipe 15 and the fourth hydraulic pipe 19 are all filled with hydraulic oil, the inner side of the frame 1 is fixedly connected to the collection frame 24, and the top of the collection frame 24 is connected to the cover plate 25 by a hinge, the collection frame 24 is provided with a bearing groove 29 on the side close to the bearing frame 3, and the inner side of the bearing groove 29 is fixedly connected to the elastic sleeve 9, the extended part of the elastic sleeve 9 is located on the inner side of the collection frame 24, the bearing groove 29 is located on the side of the bearing frame 3 at the bottom of the top cover 4, the bottom of the top cover 4 is fixedly connected to the sealing ring, and the top of the bearing frame 3 is provided with a sealing groove 37 for matching with the sealing ring.

[0044] 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 carrier frames 3 is one stage, and two samples are divided into one group to facilitate the subsequent laboratory weighing and comparison of the filter paper 44 samples. Therefore, one of the carrier frames 3 is placed between the top cover 4 and the air pipe 38, and the other carrier frame 3 is placed on the top of the support plate 30 and on the side of the push plate 35. Start the sampler 2 for constant air absorption sampling. The sampler 2 starts by constantly sucking in the dust in the factory building through the top cover 4 and the air pipe 38, and uses the filter paper 44 in the carrier frame 3 to carry the dust. The sealing groove 37 and the sealing ring are used to ensure the sealing of the connection between the top cover 4 and the carrier frame 3, and the sealing gasket 43 is used to ensure the sealing of the bottom of the carrier frame 3 and the top of the air pipe 38, so as to avoid additional dust from entering and affecting the service life of the sampler 2 and the test results.

[0045] 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 pulling 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, thereby pushing the push plate 35. At the same time, the hydraulic oil in the first hydraulic pipe 10 will move together with the fourth piston 33 when the second piston 28 is pulled, so as 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 lifted up and the support frame 3 is lifted up, and the top cover 4 is lifted up and the support frame 3 is lifted up. When the support frame 3 is lifted up, the top cover 4 is lifted up and the support frame 3 is lifted up. When the support frame 3 is lifted up, the top cover 4 is lifted up and the support frame 3 is lifted up. The present invention greatly improves the replacement rate of the filter paper 44 together with the support frame 3, avoids the time-consuming and 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. Example

[0046] Reference Figure 8-12 The inner sides of the two carrying frames 3 are connected with a flexible nano material film 36 by glue, and the inner top of the top cover 4 is fixedly connected with a plurality of ventilation pipes 40, and all the ventilation pipes 40 are provided with a plurality of air holes 41.

[0047] By utilizing the flexible nanomaterial membrane 36 set 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 nanomaterial membrane 36 can be punctured, so that the air holes 41 on the ventilation pipe 40 can collect dust and enter, thereby allowing the wind required for sampling in the factory to smoothly enter the supporting frame 3. The most critical role of the setting of the flexible nanomaterial membrane 36 is that after the sampling of the supporting frame 3 is completed, the flexible nanomaterial membrane 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 accuracy of the sampling of the supporting frame 3. After the ventilation pipe 40 is separated from the flexible nanomaterial membrane 36, the flexible nanomaterial membrane 36 will utilize the characteristics of the flexible nanomaterial membrane 36 itself to make the punctured part automatically retract. Example

[0049] The carrying frame 3 can be replaced smoothly, so that the carrying frame 3 always remains horizontal when moving. Example

[0050] Reference Figure 12 The bottom of the carrying frame 3 and the top of the air pipe 38 are both fixedly connected with a sealing gasket 43.

[0051] The sealing gasket 43 can ensure a certain degree of sealing between the bottom of the supporting frame 3 and the top of the air pipe 38, preventing external dust from directly entering the air pipe 38, thereby improving the service life of the sampler 2. Example

[0052] Reference Figure 1-3 The bottom of the first piston tube 5 is fixedly connected to the first connecting plate 6, and the top of the top cover 4 is elastically connected to the bottom of the first connecting plate 6 through several first tension springs 7. Both ends of the first hydraulic tube 10 are fixedly connected to the second connecting plate 21, and one side of the two clamping plates 22 is elastically connected to the two second connecting plates 21 respectively through the second tension springs 23. One side of the second piston tube 13 is fixedly connected to the third connecting plate 8, and both sides of the third connecting plate 8 are elastically connected to one side of the push plate 35 through the third tension spring 26. The first connecting plate 6, the second connecting plate 21 and the third connecting plate 8 are all distributed in a ring shape.

This allows the top cover 4, the clamping plates 22, and the push plate 35 to retract smoothly, thereby avoiding insufficient retraction force of the hydraulic oil in the first hydraulic pipe 10 and the second hydraulic pipe 14, which will cause the top cover 4, the clamping plates 22, and the push plate 35 to be unable to be pulled smoothly, thereby improving the flexibility of use of the equipment.

[0055] The fixing ring 39 is connected to the top cover 4 through the protrusion 42, so that the dust in the factory can smoothly enter the supporting frame 3 without delaying the connection between the top cover 4 and the supporting frame 3. At the same time, the sliders 11 on both sides of the supporting frame 3 are used to slide on the top of the support plate 30, so as to ensure the stability of the supporting frame 3 during the process of being pushed by the push plate 35, prevent the supporting frame 3 from deviating, and improve the stability of the movement of the supporting frame 3.
