Description

Technical Field

[0001] This invention relates to the field of fly ash collection, and more specifically to an automatic sampling and storage device for airborne fly ash. Background Technology

[0002] Fly ash is one of the common substances in waste disposal. The purpose of collecting samples is to understand whether fly ash is emitted from the area, the direction of the emission, and the particle size at the time of emission. The existing collection equipment has the following problems. First, the equipment is bulky and difficult to carry. To achieve better collection results, dust collection or extraction is often used to collect fly ash from the air, which requires carrying equipment such as pumps, power supplies, and batteries, making the collection process quite complicated. Second, it is impossible to determine the direction. Although the collection personnel need to collect from various directions, even after carrying the collection equipment to the laboratory, it is still impossible to determine which direction is polluted. It can only determine whether the pollution in the area is severe. In areas with many buildings, the inability to determine the direction of pollution means that it is impossible to find out the source of pollution.

[0003] To address these issues, those skilled in the art have designed an automatic air fly ash sampling and storage device. Summary of the Invention

[0004] To address the aforementioned technical shortcomings, the purpose of this invention is to provide an automatic air fly ash sampling and storage device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a collection tube and a storage chamber. The outer side of the collection tube is wrapped with an outer shell, and a pollution location monitoring component is provided inside the outer shell. A storage chamber located below the pollution location monitoring component is installed on the outer wall of the collection tube. A breathable compression chamber is connected to the bottom of the collection tube. A rotating and lifting component is provided on the outer wall of the collection tube. The bottom of the compression chamber can slide up and down and is connected to casters.

[0006] Preferably, the pollution location monitoring component includes a dyed fabric and a screening tube. The dyed fabric is located inside the outer casing, and the screening tube is connected to the middle of the collection tube and divides the collection tube into upper and lower sections. A filter screen is provided at the connection between the lower section of the collection tube and the bottom of the screening tube.

[0007] Preferably, the rotating lifting assembly includes a rotating assembly and a threaded connecting pipe. The threaded connecting pipe includes an inner pipe and an outer pipe, with the inner pipe connected to the top of the extrusion chamber and the outer pipe connected to the bottom of the collection pipe.

[0008] Preferably, the rotating assembly includes a first gear and a second gear. The center of the first gear is slidably connected to the collection tube, the outer side of the first gear is meshed with the second gear, and a drive motor is connected to the shaft end of the second gear.

[0009] Preferably, the compression chamber includes an elastic cavity and a spring. The top of the elastic cavity is fixedly connected to the outer shell, the spring is located inside the elastic cavity, and the bottom of the elastic cavity is fixedly connected to the caster wheel.

[0010] Preferably, the bottom of the outer casing is slidably connected to the caster wheel, and the outer wall of the outer casing corresponding to the dyed fabric can be made of transparent material.

[0011] Preferably, the storage chamber includes at least three sets of screens, which are equidistantly distributed from top to bottom along the outer wall of the collection tube, and the mesh size of the three sets of screens increases sequentially from top to bottom.

[0012] Preferably, each screen group contains at least two screens, which can be spliced ​​together to form a frustum structure that wraps around the outside of the collection tube. One side of each screen is connected to a tube into which the collection tube can be inserted, and the outer wall of the collection tube has a one-way opening. Preferably, the top of the collecting tube is provided with a flared mouth, and a discharge notch is opened on one side of the outer wall of the screening tube, and the discharge notch faces the same direction as the flared mouth.

[0013] Preferably, the dyed fabric is wrapped around the inside of the outer shell, the first end can be pulled out from the outer shell, and the tail end is provided with a winding mechanism. Multiple strips of dyed fabric are wound in the winding mechanism, and an easy-tear notch is provided between two adjacent strips of dyed fabric.

[0014] The beneficial effects of this invention are as follows: It takes advantage of the unevenness of the surrounding ground, allowing personnel to walk around the equipment in a small area near the contaminated area. The casters continuously push the squeezing chamber up and down repeatedly during the up-and-down motion, forming a piston-type adsorption structure. When the air is sucked in, all the fly ash from the outside can be sucked into the screen tube. Under the action of rotation, the fly ash is thrown out of the screen tube and quickly dyed onto the surface of the fabric. Excess fly ash will fall into the storage chamber to be screened and collected. When blowing air, most of the fly ash in the storage chamber can be blown up. By blowing upwards at an angle, the fly ash is lifted up a short distance and then falls down, causing the fly ash to pass through the screen and be screened. In addition to rotation, the entire process only uses the up and down movement of the casters to complete the collection and screening. At the same time, this device is lightweight, convenient and easy to collect. Attached Figure Description

For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] Example 1: This invention provides an automatic air ash sampling and storage device, such as... Figure 1-8 As shown, the system includes a collection tube 2 and a storage chamber 4. The collection tube 2 is wrapped with an outer shell 1, and a pollution location monitoring component is installed inside the outer shell 1. The storage chamber 4, located below the pollution location monitoring component, is installed on the outer wall of the collection tube 2. A breathable compression chamber 3 is connected to the bottom of the collection tube 2. A rotating lifting component is installed on the outer wall of the collection tube 2. The bottom of the compression chamber 3 can slide up and down and is connected to casters 6. The pollution location monitoring component includes a dyed cloth 5 and a sieve tube 201. The dyed cloth 5 is located inside the outer shell 1. The sieve tube 201 is connected to the middle of the collection tube 2 and divides the collection tube 2 into upper and lower sections. A filter screen is installed at the connection between the lower section of the collection tube 2 and the bottom of the sieve tube 201. The filter screen at the bottom of the sieve tube 201 can filter fly ash, allowing only gas to pass through completely. The filtered fly ash is synchronously thrown outward under the action of centrifugal force when the collection tube 2 rotates. A small amount of fly ash is smeared on the dyed cloth 5, forming black areas. The vast majority of fly ash falls into the storage chamber 4.

[0030] The rotating lifting assembly includes a rotating assembly and a threaded connecting pipe 202. The threaded connecting pipe 202 includes an inner pipe and an outer pipe. The inner pipe is connected to the top of the extrusion chamber 3, and the outer pipe is connected to the bottom of the collection pipe 2. The inner pipe and the outer pipe are connected by threads. When the collection pipe 2 is rotated by the rotating assembly, the outer pipe will rotate upward along the thread direction due to the threaded connection between the inner pipe and the outer pipe.

[0031] The rotating assembly includes gear 7 and gear 8. Gear 7 is slidably connected to the collection tube 2 at its center, and gear 8 is meshed with the outer side of gear 7. A drive motor is connected to the shaft end of gear 8. The main purpose of the rotating assembly to rotate the collection tube 2 is to receive fly ash from all directions, thereby determining the source of the fly ash. At the same time, it continuously drives the collection tube 2 to climb upwards, which is also to receive fly ash at different heights. It should be noted that the entire rotation process is very slow, giving the fly ash time to be smeared and flow out on the dyed fabric 5.

[0032] The compression chamber 3 includes an elastic cavity 301 and a spring 302. The top of the elastic cavity 301 is fixedly connected to the outer shell 1. The spring 302 is located inside the elastic cavity 301. The bottom of the elastic cavity 301 is fixedly connected to the universal wheel 6. The bottom of the compression chamber 3 can move up and down together with the universal wheel 6. The compression chamber 3 forms a piston structure, while the top of the compression chamber 3 remains fixed and cannot rotate or move up and down.

[0033] The bottom of the outer shell 1 is slidably connected to the caster 6. The outer wall of the outer shell 1 and the corresponding part of the dyed fabric 5 can be made of transparent material. The caster 6 allows the device to slide. This device is used to collect samples in the vicinity when held or hugged by a person. Since it is far from the city, the road surface is not as smooth as in the city. When the caster 6 assists the device to move on the road, it will inevitably cause the device to sway slightly up and down, which can drive the bottom of the extrusion chamber 3 to perform a piston-like reciprocating motion.

[0034] The storage chamber 4 includes at least three sets of screens, which are equidistantly distributed from top to bottom along the outer wall of the collection tube 2. The mesh size of the three sets of screens increases sequentially from top to bottom. The screens can filter different particles of fly ash. After multiple filtrations, the particle size of the fly ash can be classified. The bottom layer should be impenetrable to any fly ash particles, or it can directly reach the support plate. By classifying the fly ash, it is possible to specifically understand which particle size category the fly ash in the pollution emission belongs to, and to carry out more targeted treatment.

[0035] Each screen assembly contains at least two screens 401. The two screens 401 can be spliced ​​together to form a frustum structure that wraps around the outside of the collection tube 2. One side of the screen 401 is connected to a tube 402 that can be inserted into the collection tube 2, and the outer wall of the collection tube 2 has a one-way opening 403. The two screens 401 can be spliced ​​together to form a structure that is easy to disassemble. Fly ash generally adheres to the screen, and the collected fly ash can be quickly obtained after disassembly. The surface of the outer shell 1 is provided with an openable door to facilitate the disassembly of the internal screens 401.

[0036] The top of the collection tube 2 is provided with a funnel 203. The structure of the funnel 203 facilitates the intake of more fly ash. The outer wall of the screening tube 201 has a discharge notch on one side, and the discharge notch faces the same direction as the funnel 203. The main purpose of facing the same direction is to record the content of fly ash in that direction. Due to the slow rotation speed, the sucked fly ash will first enter the surface of the dyed cloth 5 and dye the white dyed cloth 5 black. If the black depth is different in different areas on the same dyed cloth 5, the dark area is the focus of pollution. At the same time, the transparent outer shell 1 makes it easier to see the pollution depth of the dyed cloth 5 inside.

[0037] The dyeing cloth 5 is wrapped around the inside of the outer shell 1. The first end can be pulled out from the outer shell 1, and the tail end is provided with a winding mechanism. Multiple dyeing cloths 5 are wound in the winding mechanism. There is an easy-tear notch between two adjacent dyeing cloths 5. The end of the dyeing cloth 5 is provided with a roll-up structure to hold more dyeing cloths 5. When it is necessary to replace the dyeing cloth 5, you only need to pull the old dyeing cloth 5 out of the equipment and tear it off. When working, the personnel walk on the nearby road surface while holding this device. When walking back and forth, due to the low flatness of the road surface, the caster 6 will also move up and down while rolling, which will trigger the bottom of the squeezing chamber 3 to move up and down. At the same time, the drive motor will start to drive the collection tube 2 to rotate, forming a piston reciprocating motion, which will give rise to the following two situations. When the squeezing chamber is drawing in air, a negative pressure is generated in the collection tube 2, which causes the horn 101 to absorb fly ash from the environment. The fly ash passes through the screening tube 201 but cannot pass through the filter screen at the bottom of the screening tube 201. It will remain in the screening tube 201 for a short time and fly out of the screening tube 201 due to the high speed. The fly ash will first remain on the dyed fabric 5, causing the dyed fabric 5 to turn black. The excess fly ash will fall into the storage chamber 4. At the same time as the air is drawn in, the one-way port 403 is in a closed state.

[0038] When air is blown into the compression chamber, a positive pressure is generated in the collection pipe 2, which tends to blow air outward. Since a one-way valve is installed in the collection pipe 2, the air blowing process will cause the channel to the screen pipe 201 to be closed, while the channel at the one-way port 403 will be opened, blowing air into the fly ash in the screen 401. When blowing air, the fly ash can be lifted up and fall onto the filter screen surface for repeated screening, filtering out fly ash of various particle sizes.

[0039] After the screen 401 is disassembled, the stored fly ash and dyed cloth 5 can be collected. After disassembly, a new dyed cloth 5 can be replaced for testing in new environments. The outer shell 1 can also be made into a transparent structure, so that after the fly ash dyes the dyed cloth 5, the user can directly see the specific dyeing situation of the dyed cloth 5 through the outer shell 1, determine from which position the fly ash is blown, and thus determine the direction of pollution. It should be stated that the above-described specific embodiments are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to the present invention. However, such variations, as long as they do not depart from the spirit of the present invention, should be within the scope of protection of the present invention. Furthermore, some terminology used in this specification and claims is not limiting, but merely for ease of description.
