Description

TECHNICAL FIELD

[0002] In the industrial application of the X-ray sorting machine, a large amount of hydrophilic dust is generated at the sorting station. If the dust spreads to the workshop environment or the interior of the equipment, it will not only affect the sorting accuracy, but also endanger the health of the operators, so a high-efficiency dust removal system is needed. The spray tower becomes the mainstream dust removal equipment of the X-ray sorting machine because it can capture dust through atomized droplets. The key component of the spray tower is the atomizing nozzle, and the spray range and flow distribution of the nozzle directly determine the dust removal effect.

[0003] In order to expand the coverage area of a single spray, the existing spray tower is designed with a deflectable atomizing nozzle. A large range is covered by rotating or adjusting the angle of the nozzle. However, during the deflection of the nozzle, the distance between the nozzle and the side wall of the spray tower changes periodically, and the flow rate of the nozzle remains uniform. For nozzles close to the side wall, excessive spraying will cause water to directly impact the side wall, forming a liquid accumulation, and also washing away the dust attached to the side wall, causing secondary accumulation. For nozzles far from the side wall, it is difficult to form sufficient atomization coverage with a fixed small flow rate, resulting in incomplete capture of suspended dust in the far zone and forming a dust removal blind area.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments of the present application, and the following embodiments are used to illustrate the present application.

[0021] Embodiment 1: As shown in FIG. 1, a dust removal system of an X-ray sorting machine includes a spray tower 1 connected to the X-ray sorting machine. Figures 1 to 8

[0022] The spray tower 1 is provided with an outer cover 15 at the top, and an input pipe 151 is mounted on the outer cover 15, with the end of the input pipe 151 connected to a water supply unit; ​A disc 2 is rotatably mounted on the outer cover 15. A reversing plate 23 is rotatably mounted at the center of the disc 2. Several pairs of passage cavities 24 with different bending angles are opened on the reversing plate 23. An atomizing nozzle 241 is installed at the outlet of the passage cavities 24. An adjusting column 242 adapted to it is inserted into the passage cavities 24. Both the adjusting column 242 and the passage cavities 24 are in the shape of a boss, and a gap is left between the adjusting column 242 and the passage cavities 24. The commutator plate 23 is provided with a guide groove 261, which is inclined. A synchronizing rod 25 is slidably provided on the guide groove 261, and the synchronizing rod 25 is horizontally slidably connected to the disc 2. The top of the synchronizing rod 25 is slidably connected to the vortex guide rail 252 which is in a fixed state. The rotation of the disc 2 causes the reversing plate 23 to rotate, which in turn changes the position of the atomizing nozzle 241. The synchronizing rod 25 on the reversing plate 23 slides along the vortex guide rail 252, and under the action of the guide groove 261, the reversing angle of the reversing plate 23 changes. After the angle of the reversing plate 23 changes, the gap between the adjusting column 242 and the through cavity 24 changes, increasing the flow rate of the atomizing nozzle 241 that is far from the side wall of the spray tower 1 and decreasing the flow rate of the atomizing nozzle 241 that is close to the spray tower 1.

[0023] like Figures 1 to 8 As shown in the specific embodiment, the spray tower 1 has an inlet pipe 11 and an outlet pipe 111 installed on its side wall. The outlet pipe 111 is positioned above the inlet pipe 11. Connecting flanges 12 are installed at the ends of both the inlet and outlet pipes 111, facilitating equipment connection. The end of the inlet pipe 11 is connected to the sorting station of the X-ray separator, and the end of the outlet pipe 111 is connected to the extraction unit. The inlet pipe 11 connects to the sorting station of the X-ray separator, allowing for precise introduction of dust-laden gas. The outlet pipe 111, positioned above and connected to the extraction unit, facilitates the formation of a gas flow path. The connecting flanges 12 simplify the connection process between the inlet and outlet pipes 111 and external equipment, improving installation convenience.

[0024] like Figures 1 to 8 As shown, furthermore, a guide surface 131 is provided at the bottom of the spray tower 1. The guide surface 131 is an inclined surface. A collection hood 132 is installed at the bottom of the spray tower 1, and the collection hood 132 is interconnected with the spray tower 1. A connecting pipe 133 is installed on the side wall of the collection hood 132. The connecting pipe 133 is used to discharge the water after dust settling. An mounting plate 134 is installed on the collection hood 132, and the mounting plate 134 is bolted to the bottom of the spray tower 1. The inclined guide surface 131 can guide the dust-laden wastewater to collect in the collection hood 132, which realizes the centralized collection of wastewater.

[0025] The end of the spray tower 1 is provided with an observation window 13, and the observation window 13 is provided with a tempered glass. The observation window 13 is convenient for observing the dust removal effect inside. The tempered glass in the observation window 13 can ensure the structural strength and is convenient for the operator to observe the atomization state and dust capture inside the spray tower 1 in real time, so as to adjust the equipment parameters in time according to the actual working condition.

[0026] The bottom of the spray tower 1 is provided with a boss 14, and the bottom of the boss 14 is provided with a support plate 141. The support plate 141 and the boss 14 are screwed and connected by locking bolts. The bottom of the support plate 141 is provided with four supporting legs 142. The bottom of the four supporting legs 142 is provided with a non-slip pad. The adjacent supporting legs 142 are provided with a reinforcing rib 143. The boss 14 and the support plate 141 are stably connected by the locking bolts. The four supporting legs 142 provide stable support for the spray tower 1. The non-slip pad enhances the friction between the supporting legs 142 and the ground. The reinforcing rib 143 enhances the structural strength between the supporting legs 142. The stability of the spray tower 1 during operation is ensured, and the vibration influence on the dust removal efficiency is avoided.

[0027] Example 2: The difference between the above examples and the present example is that, as shown in Figures 1 to 8 The disc 2 is provided with a sliding groove 21. The side wall of the outer cover 15 is provided with a sliding rail 211. The sliding rail 211 and the sliding groove 21 are in sliding connection. The inner side wall of the outer cover 15 is further provided with a partition plate 222. The partition plate 222 and the upper surface of the disc 2 are provided with a shunt cavity 223. The end of the input pipe 151 is arranged in the inner side wall of the shunt cavity 223. The partition plate 222 is rotatably connected with a transmission shaft 221. One end of the transmission shaft 221 is connected with the disc 2. The other end of the transmission shaft 221 is connected with the output end of a driving motor 22. The outer shell of the driving motor 22 is arranged on the outer cover 15. The sliding groove 21 and the sliding rail 211 are in sliding connection, which improves the stability of the disc 2 during rotation. The shunt cavity 223 formed by the partition plate 222 and the disc 2 can uniformly distribute the water flow from the input pipe 151 to each through cavity 24, so as to avoid the influence of uneven water flow on the atomization effect. The driving motor 22 provides power for the rotation of the disc 2 through the transmission shaft 221, so as to ensure the automatic operation of the adjusting structure.

[0028] As shown in Figures 1 to 8As shown in the specific embodiment, the inner recess 231 is provided inside the disc 2, the disc 2 is placed on the inner recess 231, the guide block 232 is installed on the side wall of the inner recess 231, the side wall of the guide block 232 is slidably connected with the side wall of the disc 2, the connecting rod 243 is installed on the top of the adjusting column 242, and the end of the connecting rod 243 is connected with the end of the disc 2. The inner recess 231 provides installation space for the reversing plate 23, the guide block 232 is slidably connected with the side wall of the disc 2, and the reversing plate 23 is assisted to stably overturn; the connecting rod 243 fixedly connects the adjusting column 242 and the disc 2, so that the position of the adjusting column 242 is stable, and the adjusting column 242 is prevented from deviating to affect the gap adjustment accuracy when the reversing plate 23 overturns.

[0029] As shown in the specific embodiment, Figures 1 to 8 Further, the notch 26 is provided on the reversing plate 23, the synchronous rod 25 is placed on the notch 26, the guide groove 261 is slidably arranged on the side wall of the notch 26, the end of the guide groove 261 near the center of the reversing plate 23 is higher than the other end, the slide rod 262 is slidably arranged in the guide groove 261, and the synchronous rod 25 is connected with the slide rod 262. The notch 26 provides installation space for the synchronous rod 25, the slide rod 262 connects the synchronous rod 25 and the guide groove 261, the sliding smoothness of the synchronous rod 25 in the guide groove 261 is optimized, and the height difference design of the guide groove 261 ensures that the synchronous rod 25 can stably drive the reversing plate 23 to overturn when sliding.

[0030] As shown in the specific embodiment, Figures 1 to 8 Further, the partition plate 222 is connected with the vortex line guide rail 252, the slide block 251 is slidably arranged on the vortex line guide rail 252, the synchronous rod 25 is connected with the top of the slide block 251, the limiting block 27 is installed on the synchronous rod 25, a plurality of pairs of through grooves 271 are provided on the disc 2, and the limiting block 27 is slidably arranged in the through groove 271. The partition plate 222 fixes the position of the vortex line guide rail 252, the slide block 251 improves the sliding fit precision of the synchronous rod 25 and the vortex line guide rail 252; the limiting block 27 and the through groove 271 are slidably connected, the horizontal sliding of the synchronous rod 25 is limited, and the deviation of the synchronous rod 25 from affecting the overturning angle of the reversing plate 23 is avoided.

[0031] As shown in the specific embodiment, Figures 1 to 8As shown, further, the limiting block 27 is provided with a limiting plate 272, the limiting plate 272 is internally provided with a limiting rod 273, the limiting rod 273 is provided with a limiting seat 274 at both ends, the limiting seat 274 is installed on the reversing plate 23, the limiting rod 273 is provided with a limiting spring 275, one end of the limiting spring 275 is clamped on the limiting plate 272, and the other end of the limiting spring 275 is clamped on the side wall of the limiting seat 274. The limiting plate 272, the limiting rod 273 and the limiting seat 274 cooperate to limit the turning range of the reversing plate 23; the elastic force of the limiting spring 275 can buffer the turning action of the reversing plate 23, so that the sudden change of the gap between the adjusting column 242 and the through cavity 24 caused by the rapid turning of the reversing plate 23 is avoided, and the stable flow regulation is ensured.

[0032] The implementation principle of the dust removal system of the X-ray sorting machine is as follows: Firstly, the air extraction unit and the water supply unit are started, the air extraction unit forms a negative pressure in the spraying tower 1 through the air outlet pipe 111, and the dust-containing gas generated in the sorting station of the X-ray sorting machine is sucked into the spraying tower 1 along the air inlet pipe 11; at the same time, the water supply unit sends the dust removal water to the shunt cavity 223 between the outer cover 15 and the partition plate 222 through the input pipe 151, the shunt cavity 223 can uniformly distribute the water flow to the through cavities 24 opened on the reversing plate 23 below the disc 2, at this time, the gap between the adjusting column 242 in the through cavity 24 and the through cavity 24 will preliminarily limit the water flow, and finally the water flow is atomized into fine droplets by the atomizing nozzle 241 at the outlet of the through cavity 24, the atomized droplets are fully contacted with the dust-containing gas in the spraying tower 1, and the preliminary capture of dust is realized.

[0033] Subsequently, the driving motor 22 is started, the output end of the driving motor 22 drives the transmission shaft 221 to rotate, the transmission shaft 221 further drives the disc 2 connected thereto to rotate synchronously, the disc 2 slides along the slide rail 211 of the outer cover 15 through the sliding groove 21 at the edge of the disc 2, to ensure the stability of the disc 2 during rotation; while the disc 2 rotates, the reversing plate 23 below the disc 2 rotates with the disc 2, the top of the synchronous rod 25 on the reversing plate 23 is slidably connected with the vortex line guide rail 252 fixed on the bottom of the partition plate 222 through the sliding block 251, with the rotation of the disc 2, the sliding block 251 moves along the track of the vortex line guide rail 252, and then drives the synchronous rod 25 to slide in the guide groove 261 of the reversing plate 23, since the guide groove 261 is in an inclined state and the end close to the center of the reversing plate 23 is higher than the other end, the sliding of the synchronous rod 25 generates a turning force on the reversing plate 23, so that the reversing plate 23 is angularly turned around the rotation connection point with the disc 2.

[0034] During the flipping process of the reversing plate 23, the adjusting column 242 (fixed to the end of the disc 2 by the connecting rod 243) in the through cavity 24 changes its relative position with the through cavity 24, thereby changing the gap size between them: for the atomizing nozzle 241 far from the side wall of the spray tower 1, the gap between the corresponding through cavity 24 and the adjusting column 242 increases, the water flow rate increases, the atomizing flow rate increases, a wider atomizing coverage area can be formed, and suspended dust in the area far from the side wall of the spray tower 1 can be effectively captured; while for the atomizing nozzle 241 close to the side wall of the spray tower 1, the gap between the corresponding through cavity 24 and the adjusting column 242 decreases, the water flow rate decreases, which avoids liquid accumulation or sewage splashing in the area close to the side wall due to excessive water flow, and reduces unnecessary waste of water resources. In this process, the limiting block 27 on the synchronous rod 25 slides along the through slot 271 of the disc 2, and the limiting plate 272 slides on the limiting rod 273 and compresses or stretches the limiting spring 275. The elastic force of the limiting spring 275 can buffer the flipping action of the reversing plate 23, ensure the smooth change of the gap between the through cavity 24 and the adjusting column 242, and avoid the influence of sudden change of flow rate on the dust removal effect.

[0035] After the dust-containing gas contacts with the atomized droplets, the dust particles are wrapped by the droplets to form dust-containing sewage. The dust-containing sewage flows along the inclined guide surface 131 at the bottom of the spray tower 1 under the action of gravity, is finally collected in the collecting cover 132, and is then discharged to the subsequent sewage treatment system through the connecting pipe 133 on the side wall of the collecting cover 132, so that the centralized treatment and recycling of the sewage are realized. The operator can observe the atomizing state and dust capture condition in the tower through the tempered glass embedded in the observation window 13 at the end of the spray tower 1, so as to adjust the equipment parameters according to the actual working condition. In addition, the spray tower 1 is lapped on the support plate 141 through the boss 14, the locking bolt ensures the stable connection of the two, and the anti-skid pad at the bottom of the support leg 142 and the reinforcing rib 143 between the adjacent support legs 142 together ensure the structural stability of the spray tower 1 during operation, so as to avoid the influence of equipment vibration on the dust removal efficiency.

[0036] Finally, the clean gas after atomizing and dust removal is discharged along the gas outlet pipe 111 under the negative pressure of the air extraction unit, and the entire purification process of the dust-containing gas is completed. The flow directional distribution of the atomizing nozzle 241 is realized by the flipping adjustment of the reversing plate 23, which not only improves the uniformity and effectiveness of dust capture in the spray tower 1, but also reduces the consumption of water resources and the cost of subsequent sewage treatment, and adapts to the efficient purification demand of the dust-containing gas of the X-ray sorting machine.
