Description

Technical Field

[0001] The invention relates to the technical field of solid pollution monitoring, and in particular to a monitoring device and a monitoring method for a solid pollution source area. Background Art

[0002] Solid waste can be roughly divided into three types according to its source: domestic waste, general industrial solid waste and hazardous waste. In addition, there are agricultural solid waste, construction waste and abandoned soil. If solid waste is not properly collected, utilized and treated, it will pollute the atmosphere, water bodies and soil, and endanger human health. Industrial solid waste refers to solid waste generated in production activities such as industrial transportation, such as steel slag, boiler slag, fly ash, coal gangue, industrial dust, etc. In some specific work places, such as textile workshops, static electricity and dust generated during the textile process can easily cause fires in the workshop, and even explosions in serious cases. At the same time, certain processes in cotton spinning, wool spinning, linen spinning and silk spinning factories, such as cotton blending, wool selection, soft linen, opening and combing, will discharge a lot of dust. Some spinning equipment, such as opening and cleaning machinery, uses airflow to transport and agglomerate fibers or remove waste during the processing process, and will also discharge a lot of dusty air. In a cotton spinning mill with 50,000 spindles, the exhaust volume of the opening and cleaning machine alone is more than 120,000 m3 / h. If textile factories do not take air purification measures, a large amount of dusty air will inevitably spread widely, seriously polluting the workshop and the surrounding environment, directly endangering the health of employees and affecting product quality. The dust formed in the spinning production is a mixture of particles of various substances, and the substances are mainly divided into two categories: organic and inorganic. Organic matter includes fragments, debris, short lint, seed crumbs, leaf crumbs, etc. of cotton, flax, jute, wool, silk and chemical fibers; inorganic matter includes soil, sand, asbestos and glass dust. Some dusts (such as cotton dust and hemp dust) also contain a certain proportion of silica dust. Most of these dusts are mixed with fibers during the raw material harvesting process (such as picking cotton, shearing wool or retting), or during processing, transportation and storage.

[0003] In the current existing technology, in order to monitor the dust concentration in a textile workshop, the light scattering method is generally used to detect the dust concentration in the workshop. However, the dust concentration detection of the entire workshop can only obtain the dust concentration of the entire workshop, and the dust source cannot be accurately and effectively detected. If the dust concentration is high in a certain place in the workshop, while the dust concentration in other areas is low, the dust concentration in the workshop as a whole will not reach the alarm warning line, which will easily cause a fire and affect the daily production and life of the factory. In view of this, we propose a monitoring device and a monitoring method for the solid pollution source area. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a monitoring device and a monitoring method for a solid pollution source area, which can effectively solve the existing problem of being unable to accurately detect the dust concentration in the pollution source area.

The multiple sliding columns are connected by a blackout cloth and the other end of the blackout cloth is connected to the inner wall of the arc hole; the blackout cloth in the arc hole is opened with corresponding apertures passing through the top plate limiter and the bottom plate limiter.

[0009] Furthermore, the starting point of the hole opening of the closing plate associated with the arc-shaped top plate is located at the top, and the hole is opened in the opposite direction of the rotation of the rotating rod; the starting point of the hole opening of the closing plate associated with the arc-shaped bottom plate is located at the bottom, and the hole is opened in the opposite direction of the rotation of the rotating rod; the arc range of the two closing plates is 110-120°; the rotation range of the rotating rod is 0-90°.

[0010] Furthermore, the arcs of the arc-shaped top plate and the arc-shaped bottom plate coincide with a circle with the central axis of the support rod as the center.

[0011] Furthermore, a cavity is provided inside the arc-shaped top plate, and evenly distributed dust suction holes are provided at the bottom end of the arc-shaped top plate. The cavity inside the arc-shaped top plate is connected to the dust collector and the dust suction holes respectively.

[0012] Furthermore, a sliding rail is provided on the inner wall of the cavity of the arc-shaped top plate, and a cleaning arc-shaped rod is slidably connected inside the arc-shaped top plate; a cylindrical groove is provided at the bottom end of the cleaning arc-shaped rod, and a spring is provided on the inner wall of the cylindrical groove on the cleaning arc-shaped rod, one end of the spring is fixedly connected to a telescopic column, and one end of the telescopic column is processed into an arc shape; the diameter of the telescopic column is slightly smaller than the diameter of the dust suction hole.

[0020] The present invention will be further described below in conjunction with the embodiments.

[0021] Example: A monitoring device for solid pollution source areas, such as Figure 1-9 As shown, it includes a moving seat 100, which is slidably connected to a track. The track is not shown in the figure. It should be noted that, taking a textile workshop as an example, the track is installed under a winding device or a spinning device, and the moving seat 100 carries a monitoring device on the track to monitor each station on the device; one end of the moving seat 100 is fixedly connected to a support rod 200; Two closed plates 300, the inner walls of the opposite sides of the two closed plates 300 are respectively provided with a receiving plate 301 and a laser emitter 302, the receiving plate 301 and the laser emitter 302 are located on the same central axis, and the area between the two closed plates 300 is the monitoring space. It should be noted that the receiving plate 301 acts like a light trap, and the laser emitted by the laser emitter 302 is absorbed or scattered by dust in the monitoring space, and then sensed by the receiving plate 301, and the data is uploaded to the terminal. After the terminal analyzes the data and the reverse, the dust concentration in the monitoring space can be measured. If the dust concentration in the monitoring space is greater than the warning line, the monitoring space is The measuring space is marked; the lower ends of the two closing plates 300 are fixedly connected with a rotating rod 310, and the lower ends of the two rotating rods 310 are rotatably connected to the support rod 200 through a collar. Specifically, the collar on one rotating rod 310 is connected to the driving device on the support rod 200 at the same time, and a connecting rod 311 is fixedly connected between the two rotating rods 310. It should be noted that the two rotating rods 310 and the closing plates 300 thereon are connected into a whole by the connecting rod 311, which, on the one hand, reduces the number of driving devices, and on the other hand, ensures that the volume of the monitoring space between the two closing plates 300 remains unchanged, thereby improving the accuracy of monitoring; The arc-shaped top plate 400 is located between the two closed plates 300 and is always above the monitoring space, and is used to block the interference of light in the workshop on the dust concentration detection behavior; rotating shafts 410 are provided on both sides of the top of the arc-shaped top plate 400 through connecting plates, and a blackout cloth is wound on the rotating shaft 410. Specifically, the rotating shaft 410 is driven to rotate by an external driving device so that the blackout cloth falls to perform a blackout operation on both sides of the detection space; the arc-shaped bottom plate 500 is located between the two closed plates 300 and is always below the monitoring space, and is used to block the reflection of the bottom plate in the workshop from interfering with the dust concentration detection behavior; it should be noted that the two closed plates 300, the arc-shaped top plate 400, the arc-shaped bottom plate 500 and the fallen blackout cloth together surround and form a monitoring space, and the receiving plate 301 and the laser transmitter 302 monitor the dust concentration inside the light-tight monitoring space to improve the accuracy of monitoring; Specifically, arc-shaped holes 303 are provided on the two closing plates 300, and sliding grooves are provided inside the arc-shaped holes 303. A plurality of sliding posts 320 are provided inside the arc-shaped holes 303. Ball bearings are provided at both ends of the plurality of sliding posts 320 to roll on the sliding grooves inside the arc-shaped holes 303. The plurality of sliding posts 320 are connected by a blackout cloth, and the other end of the blackout cloth is connected to the inner wall of the arc-shaped holes 303. In this solution, the blackout cloth in the arc-shaped holes 303 is provided with corresponding apertures that pass through the top plate limiter 430 and the bottom plate limiter 510, so as to avoid light leakage caused by the change of position of the top plate limiter 430 and the bottom plate limiter 510 when the arc-shaped top plate 400 and the arc-shaped bottom plate 500 are moved, thereby ensuring the opacity between the two closing plates 300. Furthermore, one end of the arc-shaped top plate 400 is fixedly connected to a top plate stopper 430, and the bottom end of the top plate stopper 430 is fixedly connected to a rotating disk 431. One side of the rotating disk 431 is rotatably connected to the outside of a closed plate 300 through a rotating shaft, and the bottom end of the rotating disk 431 is fixedly connected to a top plate bearing block 432. In this solution, in order to keep the arc-shaped top plate 400 always located above the monitoring space to block the light from above, the gravity of the top plate bearing block 432 is used to keep it covering the monitoring space. The linkage between the rotating disk 431 and the closing plate 300 ensures that the position of the arc-shaped top plate 400 will not be affected during the rotation of the closing plate 300; the top plate limiter 430 is slidably connected to an arc-shaped hole 303 of the closing plate 300; a cavity is provided inside the arc-shaped top plate 400, a dust collector 420 is provided at the top of the arc-shaped top plate 400, and the dust collector 420 is used to clean the dust in the monitoring space; the bottom of the arc-shaped top plate 400 is provided with evenly distributed dust suction holes 421, and the air inside the arc-shaped top plate 400 is The cavity is connected to the dust collector 420 and the dust collection hole 421 respectively. It should be noted that the dust collector 420 can recycle the dust in the monitoring space, and recycle the dust after the detection is completed to avoid subsequent accumulation of dust; the inner wall of the cavity of the arc-shaped top plate 400 is provided with a slide rail, and a cleaning arc rod 440 is slidably connected inside the arc-shaped top plate 400. A cylindrical groove is provided at the bottom end of the cleaning arc rod 440, and a spring 441 is provided on the inner wall of the cylindrical groove on the cleaning arc rod 440. One end of the spring 441 is fixedly connected to a telescopic Column 442, one end of telescopic column 442 is processed into an arc shape, and the diameter of telescopic column 442 is slightly smaller than the diameter of dust suction hole 421. It is worth noting that balls are arranged on both sides of cleaning arc rod 440 and slide on the slide rail in the cavity of arc top plate 400. The telescopic column 442 thereon impacts the inside of dust suction hole 421 at the bottom of arc top plate 400 under the action of spring 441, so that the dust in the monitoring space of vacuum cleaner 420 is covered on the dust suction hole 421. Larger particles, such as clumped textile cotton wool; Furthermore, one end of the arc bottom plate 500 is fixedly connected to a bottom plate stopper 510, and the bottom plate stopper 510 is slidably connected to the arc hole 303 of another closing plate 300. A bottom plate bearing block 520 is fixedly connected below the arc bottom plate 500. In this solution, the bottom plate bearing block 520 provides gravity so that the arc bottom plate 500 is always located directly below the monitoring space. Under the action of the top plate bearing block 432 and the bottom plate bearing block 520, the arc top plate 400 and the arc bottom plate 500 are always in a parallel state. And it is worth pointing out that Fig.10As shown, the arc hole 303 on the closing plate 300 associated with the arc top plate 400 has an opening starting point located at the top, and is opened in the opposite direction of the rotation of the rotating rod 310. The arc hole 303 on the closing plate 300 associated with the arc bottom plate 500 has an opening starting point located at the bottom, and is opened in the opposite direction of the rotation of the rotating rod 310. The arc range of the arc holes 303 on the two closing plates 300 is 110-120°, and the rotation range of the rotating rod 310 is 0-90°. In this solution, the actual monitoring space is not on the moving path of the monitoring device. When it moves to the vicinity of the monitoring space, the rotating rod 310 is rotated so that the arc top plate 40 0. The arc bottom plate 500, the shading cloth and the two closing plates 300 surround the monitoring space, thereby preventing the monitoring device from causing a significant impact on the air in the monitoring space during its movement, thereby affecting the monitoring data; the arcs of the arc top plate 400 and the arc bottom plate 500 coincide with a circle with the central axis of the support rod 200 as the center. In this solution, if the arcs of the arc top plate 400 and the arc bottom plate 500 coincide with a circle with the central axis of the receiving plate 301 as the center, then the arc top plate 400 and the arc bottom plate 500 will overlap with the monitored space in the process of moving with the closing plate 300, making the monitoring data inaccurate; Furthermore, a magnet sheet is pasted on the bottom of the shading cloth wrapped around the rotating shaft 410, and magnetic attraction areas are provided at the top ends of both sides of the curved bottom plate 500. The magnet sheet on the shading cloth and the magnetic attraction areas on the curved bottom plate 500 attract each other. It is worth noting that the attraction between the magnet sheet and the magnetic attraction area is not strong, which makes it convenient for the rotating shaft 410 to rotate in the opposite direction to continue to wrap the shading cloth around the rotating shaft 410. At the same time, the attraction between the two ensures that the two sides of the monitoring space will not shake easily, thereby ensuring the stability of the monitoring space.

[0022] In this plan, taking the textile workshop as an example, Fig.11 As shown, the staff installs the track under the production equipment in the textile workshop, and then installs the mobile seat 100 on the track to slide. According to the distance between each station on the production equipment, the distance of each movement of the mobile seat 100 is set to ensure that the mobile seat 100 can reach the next station each time it moves. At the same time, the angle of rotation of the rotating rod 310 driven by the external driving device is set so that the monitoring space can be set in the working area of ​​the station each time it rotates. Finally, the dust concentration warning line and the dust concentration acceleration line are set. If the value exceeds this value, the place is marked, otherwise it is recorded as normal. Initially, the closing plate 300 and the support 200 are on the same vertical plane; Work preparation, the moving seat 100 moves to the bottom of the workstation on the production equipment, and the external driving device drives the rotating rod 310 to rotate. The rotating rod 310 makes a circular motion around the supporting rod 200 and rotates with the closing plate 300 and the laser emitter 302 and the receiving plate 301 thereon. At this time, the arc bottom plate 500 always keeps the convex surface facing up under the gravity of the bottom plate bearing block 520, that is, the arc bottom plate 500 and the bottom plate weighing block 520 are in a stationary state when the moving seat 100 is used as a reference system, and in a rotating state when the closing plate 300 is used as a reference system. At this time, the bottom plate limiter 510 slides in the corresponding arc hole 303, and the sliding column 320 in the arc hole 303 moves in the slide groove under the squeezing of the bottom plate limiter 510. At the same time, the shading cloth inside the arc hole 303 continues to keep the arc hole 303 opaque, and the arc top plate 400 is under the gravity of the top plate bearing block 432. The top plate 400, the rotating disc 431 and the top plate weighing block 432 are in a stationary state when the moving seat 100 is used as a reference system, and are in a rotating state when the closing plate 300 is used as a reference system. At this time, the top plate limiter 430 slides in the corresponding arc hole 303 with the assistance of the rotating disc 431, and the sliding column 320 in the arc hole 303 moves in the slide groove under the squeezing of the top plate limiter 430. At the same time, the shading cloth inside the arc hole 303 continues to maintain the opacity of the arc hole 303. When the closing plate 300 rotates to the designated monitoring space, the rotating shaft 410 rotates to put down the shading cloth so that the magnet sheet thereon and the magnetic suction area on the arc bottom plate 500 attract each other, so that the monitoring space forms a light-tight environment in six directions, thereby avoiding the influence of the external environment on the dust concentration measured by the light absorption method, and improving the accuracy of monitoring; During operation, the laser transmitter 302 emits a laser which passes through the monitoring space to reach the receiving plate 301. The light received by 301 is converted into data and uploaded to the system terminal. The dust concentration in the current monitoring space is calculated and analyzed based on the scattering and absorption of light passing through the dust. If the dust concentration exceeds the dust concentration warning line, the dust concentration is marked as exceeding the standard, otherwise it is marked as normal. Then the vacuum cleaner 420 is operated to recycle the dust inside the monitoring space and clear the dust concentration inside the current monitoring space. During the operation of 420, the cleaning arc rod 440 moves inside the arc top plate 400. With the help of the spring 441, the telescopic column 442 on the cleaning arc rod 440 extends out of the dust suction hole 421 when passing through the dust suction hole 421 below 400, thereby dispersing larger balls of thread and cotton balls, thereby facilitating their passage through the dust suction hole 421 and avoiding the dust in the monitoring space. If the dust is not cleaned thoroughly, it will affect the subsequent dust concentration growth rate detection. After cleaning, the rotating shaft 410 drives the blackout cloth to roll up. At this time, the two directions of the detection space are exposed in the work station of the equipment. At this time, the dust generated by the production of the work station can easily enter the area. After waiting for 10 minutes, the rotating shaft 410 drives the blackout cloth to fall so that the magnet sheet on it and the magnetic attraction area on the arc bottom plate 500 attract each other, and the dust concentration in the monitoring space is detected again. If the dust concentration exceeds the dust concentration growth rate line, it is marked as an abnormal operation, otherwise it is marked as normal. Then the vacuum cleaner 420 repeats the above work to clean the dust. Then the instantaneous dust concentration and growth rate of the work station have been detected. The external drive device drives the rotating rod 310 to rotate, so that the device is restored, and reaches the next work station under the movement of the movable seat 100. Repeat the above operation until all the work stations on the production equipment are detected.

[0023] A monitoring method for a monitoring device for a solid pollution source area, comprising: S1: Build a track under the production line to be tested, and install the monitoring equipment on the track, and set the single moving distance of the moving seat 100, the rotation angle of the rotating rod 310 and the monitoring time accordingly; S2: The moving seat 100 moves to the vicinity of the next work station, and the external driving device drives the rotating rod 310 to rotate so that the closing plate 300 moves to the monitoring space, and then the rotating shaft 410 is rotated to lower the blackout cloth wrapped thereon. At this time, the arc-shaped top plate 400, the arc-shaped bottom plate 500, the two closing plates 300 and the blackout cloth surround the monitoring space; S3: The laser transmitter 302 emits laser, and the receiving board 301 absorbs and uploads the data to the terminal for analysis. If the dust concentration exceeds the warning line, the workstation is marked as having excessive dust concentration; S4: The vacuum cleaner 420 starts to clean the dust in the monitoring space, then the rotating shaft 410 recycles the shading cloth. After waiting for 10 minutes, the rotating shaft 410 puts down the shading cloth again, and the laser transmitter 302 continues to emit laser light. The receiving plate 301 absorbs and uploads the data to the terminal for analysis. If the dust concentration exceeds the warning line, the workstation is marked as having an excessive dust concentration growth rate, and the vacuum cleaner 420 starts again to clean the dust in the monitoring space. S5: Repeat the above steps S2-S4 until all workstations of the production line under test are monitored and then stop working.

[0024] Specifically, in step S3, the instantaneous dust concentration of the equipment is detected. Then in step S4, after the dust concentration in the detection space is cleaned, the monitoring space is reopened. Within 10 minutes, the workstation continues to generate dust. At this time, the blackout cloth is lowered again to monitor it. This is an interval detection of dust concentration, which allows the staff to know the working conditions of each workstation and make detailed analysis.
