Description

Technical Field

[0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to a conveyor circulation purification dust collector. Background Art

[0002] As a transportation method with strong climbing ability, continuous transportation, high productivity, short transportation distance and low cost, belt conveyor is a continuous action material transportation equipment widely used in various factories and mines. Especially for the situation of large height difference between different production workshops, the superiority of belt conveyor is more significant, but it also constitutes the main dust-producing link in such production workshops. In order to eliminate the positive pressure and dust generated by the impact of falling materials, negative pressure dust collection devices are generally installed at the falling point of belt conveyor.

[0003] The pulse dust collector is a new type of high-efficiency pulse dust collector improved on the basis of the bag dust collector. It combines the advantages of various pulse jet dust collectors with chamber backblowing, overcomes the shortcomings of insufficient chamber cleaning intensity and uneven distribution of inlet and outlet air, and expands the scope of application. The pulse dust collector filters through a filter cartridge with a metal skeleton inside, so that the dust is captured on the outer surface of the filter cartridge. The purified gas enters the cleaning chamber above the filter cartridge chamber and is collected at the air outlet for discharge.

[0004] When the filter cartridge is back-blown and cleaned by pulse jet, the dust on the outer surface of the filter cartridge will generate secondary dust, which will directly lead to secondary pollution and cause material waste. If the dust collector is started or other measures are taken to deal with the secondary dust, the cleaning frequency and operating cost of the dust collector will be greatly increased, and the working efficiency of the dust collector will be reduced.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a conveyor circulation purification dust collector.

DETAILED DESCRIPTION

[0055] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0056] like Figure 1-Figure 14 As shown, a conveyor circulation purification dust collector in one embodiment of the present invention includes a dust collector chassis, an air compression mechanism 30, an induced draft fan 50, two groups of filter components 60 and a pulse spray component 70.

[0057] like Figure 1 As shown, a dust removal and purification chamber and a clean air flow chamber are arranged inside the dust collector chassis, and a dust suction port is opened below the dust removal and purification chamber. The diameter of the dust suction port is larger than the outer diameter of the two groups of filter components 60, ensuring a sufficiently large dust suction area to avoid dust overflow.

[0058] An air outlet 40 is provided on one side of the clean air flow chamber, and an induced draft fan 50 is fixedly installed inside the clean air flow chamber. The induced draft fan 50 is connected to a frequency conversion controller through electric wires, so as to conveniently control the operating power of the induced draft fan 50. The input end of the induced draft fan 50 is connected to the inside of the clean air flow chamber, and the output end of the induced draft fan 50 is connected to the inside of the air outlet 40. The induced draft fan 50 can extract clean air from the inside of the clean air flow chamber after being filtered by the filter assembly 60, and discharge it through the air outlet 40.

[0059] The induced draft fan 50 adopts the above-mentioned layout method and does not need to be used with pipelines, which effectively reduces energy loss, ensures the working efficiency of the induced draft fan 50, and saves energy.

[0060] Among them, a muffler is fixedly installed inside the air outlet 40, and the muffler effectively reduces the noise of the air outlet 40, and effectively reduces the noise pollution during the operation of the dust collector.

[0061] An outlet dust concentration detection device 41 is fixedly installed inside the air outlet 40. The outlet dust concentration detection device 41 can detect dust residue in the exhaust air in real time. When the dust residue in the exhaust air is abnormal, it can be discovered in time, thereby improving the reliability of the dust collector.

[0062] A control module is fixedly installed on one side of the clean airflow chamber. The control module includes a PLC frequency conversion control cabinet 10 and an intelligent control cabinet 20. The operation of the dust collector can be controlled by the PLC frequency conversion control cabinet 10 and the intelligent control cabinet 20. A heat sink 11 is installed on the back of the PLC frequency conversion control cabinet 10. The heat sink 11 is used for auxiliary heat dissipation during the operation of the PLC frequency conversion control cabinet 10. Among them, the heat sink 11 is located inside the clean airflow chamber. By using the air flow inside the clean airflow chamber, the heat dissipation efficiency of the heat sink 11 can be significantly improved, thereby improving the heat dissipation during the operation of the PLC frequency conversion control cabinet 10 and ensuring safe operation.

[0063] like Figure 1 and Figure 2 As shown, an air compression mechanism 30 is installed inside the clean air flow chamber, and the air compression mechanism 30 includes an oil-free air compressor 31, an air storage tank 33, a compressed air dryer 34 and a water storage tank 35 which are sequentially fixed inside the clean air flow chamber.

[0064] The input end of the oil-free air compressor 31 is connected to the interior of the clean air flow chamber. By utilizing the positive pressure state inside the clean air flow chamber, the pressure burden on the air inlet end of the oil-free air compressor 31 can be effectively reduced, which is conducive to the oil-free air compressor 31 to produce compressed air more easily and extend the service life of the oil-free air compressor 31.

[0065] The output end of the oil-free air compressor 31 is connected to the inside of the air tank 33, and the compressed air produced by the oil-free air compressor 31 can be stored in the air tank 33. A Q-level filter 32 is fixedly installed at the output end of the oil-free air compressor 31, which can perform preliminary filtering on the compressed air.

[0066] The input end of the compressed air dryer 34 is connected to the inside of the air storage tank 33, and the compressed air dryer 34 is used to dry the compressed air and remove moisture from the compressed air.

[0067] The end of the compressed air dryer 34 is also sequentially installed with a P-level filter 37, an S-level filter 38 and a pressure reducing valve 39. Among them, the P-level filter 37 and the S-level filter 38 are used to perform secondary filtration on the dried compressed air, so as to obtain sufficiently clean compressed air, and finally the compressed air is reduced in pressure by the pressure reducing valve 39 and used for pulse spraying.

[0068] The water generated by the compressed air inside the air storage tank 33, the water generated by the compressed air dryer 34 drying the compressed air, and the water generated by the compressed air filtered by the Q-level filter 32, the P-level filter 37, and the S-level filter 38 can all flow into the water storage tank 35, thereby collecting and storing the by-product of air compression - water.

[0069] The dust collector has an integrated design, a compact structure, an ingenious layout, saves energy, and has broad prospects for promotion and use.

[0070] Two sets of filter assemblies 60 are fixedly installed inside the dust removal purification chamber to filter dust particles. The two sets of filter assemblies 60 can be operated simultaneously to perform efficient dust removal operations. They can also be operated alternately in a cycle to facilitate non-stop cleaning, ensuring that the dust collector can operate continuously to adapt to the continuously operating conveyor.

[0071] like Figure 3 and Figure 4 As shown, the filter assembly 60 includes a fixed plate 61, which is fixedly mounted on the top of the dust removal and purification chamber. A plurality of rows of filter cartridges 62 and a plurality of rows of transverse brackets 64 are fixedly mounted on the bottom end of the fixed plate 61.

[0072] Preferably, the filter cartridge 62 may be made of a nanofiltration membrane, polyester fiber, etc., which has a good waterproof effect, is not damaged by water, and does not cause bag sticking.

[0073] Among them, multiple exhaust holes 611 corresponding to the multiple rows of filter cartridges 62 are opened on the fixed plate 61. The interiors of the multiple rows of filter cartridges 62 are connected to the interior of the clean airflow chamber through the multiple exhaust holes 611. The air filtered by the filter cartridges 62 can enter the interior of the clean airflow chamber through the air holes 611.

[0074] like Figure 6 and Figure 7 As shown, the multiple rows of transverse brackets 64 include multiple rows of external attachment rings 641. The specific number of each row of external attachment rings 641 is the same as the specific number of each row of filter cartridges 62. That is, a group of external attachment rings 641 is sleeved outside each group of filter cartridges 62. A connecting block 642 is welded and fixed between two adjacent groups of external attachment rings 641 in each row, and each row of external attachment rings 641 is connected in series into a whole through the connecting block 642.

[0075] Among them, Figure 8As shown, the outer ring 641 and the connection block 642 are both hollow structures, and a passage is formed inside the outer ring 641 and the connection block 642 as a whole, which can allow water to flow.

[0076] like Figure 6 As shown, the upper end surface of the outer ring 641 is provided with a first groove 643, and a plurality of groups of atomizing nozzles 644 distributed in a circumference are fixedly mounted on the inner wall of the first groove 643, and the plurality of groups of atomizing nozzles 644 are all connected to the above-mentioned passage, and the water inside the passage can be atomized and sprayed out through the atomizing nozzles 644. The plurality of groups of atomizing nozzles 644 spray water mist to the outer surface of the filter cartridge 62 at the same time, and the dust particles on the outer surface of the filter cartridge 62 can be combined with each other to form a cake material through the water mist before the filter cartridge 62 is pulse-sprayed and cleaned.

[0077] In addition, the particle size of the water mist sprayed from the atomizing nozzle 644 can be accurately controlled by adjusting the pressure, so as to accurately control the humidity of the dust particles on the surface of the filter cartridge 62, better humidify the dust particles, and better combine the dust particles.

[0078] Preferably, the size of the water mist particles can be controlled at 0-20 μm.

[0079] like Figure 3 and Figure 5 As shown, a lifting mechanism is installed on multiple rows of transverse brackets 64, and the lifting mechanism includes a pair of upright frames 63, which are welded and fixed on both sides of the bottom end of the fixing plate 61, and a plurality of groups of track grooves 631 corresponding to the number of rows of transverse brackets 64 are opened on the opposite sides of the pair of upright frames 63. Support seats 66 are welded and fixed on both sides of each row of transverse brackets 64, and two groups of motor running wheels 661 are installed on the support seats 66, and one side of the two groups of motor running wheels 661 is rollingly connected to the inside of the track groove 631.

[0080] Specifically, by the movement of the motor walking wheel 661 inside the track groove 631, the transverse bracket 64 can be driven to rise and fall along the axial direction of the filter cartridge 62. Before pulse blowing, the transverse bracket 64 first descends from the top to the bottom, and then rises and resets from the bottom, spraying the dust particles on the outer surface of the filter cartridge 62 with water mist twice, so that the atomizing nozzle 644 can spray water mist on the surface of the filter cartridge 62 comprehensively and multiple times, ensuring that the dust particles can effectively form cakes.

[0081] In this way, when the filter cartridge 62 is pulse-backblown, the dust particles attached to the outer surface of the filter cartridge 62 can be blown off as block materials without secondary dust generation, thereby effectively avoiding secondary pollution, eliminating the need for secondary dust treatment, greatly improving the working efficiency of the dust collector, and reducing operating costs.

[0082] It is worth noting that, since the generation of secondary dust is avoided, dust particles are no longer accumulated inside the dust collector, reducing the workload of the dust collector. At the same time, the dust particles can be transformed into block materials during the cleaning process and fall on the second belt 90, mixed with the material being transported and continue to be transported, eliminating the step of processing the collected dust particles, which greatly facilitates the use of the dust collector.

[0083] like Figure 8 As shown, a second groove 647 is formed on the lower end surface of the outer ring 641. The second groove 647 enables the outer ring 641 to serve as a blocking cover to prevent bulk materials from splashing outward during pulse blowing.

[0084] Specifically, when performing pulse jet cleaning, the travel speed of the motor travel wheel 661 can be controlled to control the lifting speed of the transverse bracket 64, so that the transverse bracket 64 can move downward synchronously with the ejected airflow. When the airflow passes through, the cake-like material will be broken into blocks and splash outward. At this time, the block material will splash into the interior of the second groove 647, and will be blocked and intercepted, falling vertically along the inner wall of the second groove 647.

[0085] In this way, the bulk materials can be prevented from splashing onto the adjacent filter cartridge 62, thereby avoiding contamination of the adjacent filter cartridge 62, improving the cleaning effect of the filter cartridge 62, and ensuring that the bulk materials can fall smoothly onto the second belt 90, thereby facilitating the recovery of the bulk materials.

[0086] It is worth noting that the wet block material falls onto the material covering the second belt 90, which can also avoid the generation of floating dust during the material transportation process, and is more environmentally friendly.

[0087] like Figure 8 and Fig. 9 As shown, a deep cleaning assembly is installed on the outer ring 641, and the deep cleaning assembly includes a rotating ring 645. A boss 646 is provided inside the outer ring 641. The rotating ring 645 is rotatably connected to the boss 646 through a ball bearing and can rotate flexibly on the boss 646.

[0088] like Fig.10 and Fig.11 As shown, multiple sets of blades 6451 are fixedly installed on the outer wall of the rotating ring 645. When the transverse bracket 64 is rising, the multiple sets of blades 6451 can drive the rotating ring 645 to rotate as a whole with the help of wind force; and when the transverse bracket 64 is descending, the blades 6451 are blocked by the boss 646 and cannot be driven by wind force, and thus will not drive the rotating ring 645 to rotate.

[0089] Four sets of soft plates 6452 are fixedly mounted on the inner wall of the rotating ring 645, and the four sets of soft plates 6452 are all inclined toward the rotation direction of the rotating ring 645. When the rotating ring 645 rotates, the four sets of soft plates 6452 are subjected to reverse resistance and centrifugal force, forcing the four sets of soft plates 6452 to rotate and deform, so that one end thereof gradually approaches the filter cartridge 62.

[0090] Brushes 6453 are fixedly installed on the four groups of soft plates 6452. When the rotating ring 645 is stationary, the brushes 6453 do not contact the outer surface of the filter cartridge 62. When the rotating ring 645 rotates to force the soft plates 6452 to produce rotational deformation, the brushes 6453 will gradually approach the filter cartridge 62 and finally contact its outer surface, thereby cleaning the outer surface of the filter cartridge 62.

[0091] like Figure 8 and Fig.12 As shown, the boss 646 has multiple groups of through holes on one side facing the axis of the rotating ring 645, and soft capsules 6461 are fixedly installed inside the multiple groups of through holes. The soft capsules 6461 can expand to contact with the rotating ring 645 as the water pressure increases. In the process of the atomizing nozzle 644 spraying water mist on the surface of the filter cartridge 62, due to the existence of water pressure, the multiple groups of soft capsules 6461 will expand to contact with the rotating ring 645, and the rotating ring 645 will be locked and fixed by friction. At this time, even if the horizontal bracket 64 rises, the rotating ring 645 cannot rotate. In other words, in the process of spraying water mist, whether the horizontal bracket 64 rises or falls, the brush 6453 on the rotating ring 645 will not clean the surface of the filter cartridge 62.

[0092] When the transverse bracket 64 descends following the pulse-blown gas, that is, after the pulse-blown cleaning, during the upward reset process of the transverse bracket 64, since water mist is no longer sprayed, the water pressure disappears, the soft bag 6461 automatically shrinks and no longer contacts the rotating ring 645. At this time, the rotating ring 645 can rotate under the action of wind force, thereby deforming the soft plate 6452. At this time, the brush 6453 can contact the surface of the filter cartridge 62 to clean the surface of the filter cartridge 62.

[0093] By cleaning the surface of the filter cartridge 62 after pulse spraying, the filter cartridge 62 can be deeply cleaned, thereby avoiding affecting the working efficiency of the filter cartridge 62 due to inadequate cleaning and ensuring efficient operation of the dust collector.

[0094] like Figure 7 As shown, a spray nozzle 6421 is fixedly installed below the connecting block 642 . The spray nozzle 6421 is inclined toward the adjacent filter cartridge 62 , and a solenoid valve is installed on the spray nozzle 6421 for controlling the operation of the spray nozzle 6421 .

[0095] When the dust collector is not working, the surface of the filter cartridge 62 can be rinsed with water by the spray nozzle 6421. The external water spraying has a better cleaning effect and can remove stubborn stains on the surface of the filter cartridge 62 that cannot be cleaned by pulse blowing. After each operation of the dust collector, the cleanliness of the outer surface of the filter cartridge 62 can be ensured by spraying water, and the filter cartridge 62 can be simply maintained, which is conducive to ensuring the working efficiency of the filter cartridge 62 and extending the service life of the filter cartridge 62.

[0096] like Figure 1 and Figure 2 Combination Figure 3 and Figure 4 As shown, the water storage tank 35 is connected to a water supply system, which includes a water distribution pipe 65, on which a booster pump 36 is fixedly installed, and one end of the water distribution pipe 65 is connected to the inside of the water storage tank 35. Multiple groups of water supply pipes 651 are fixedly installed on the water distribution pipe 65, and the water distribution pipe 65 can inject water into the passages inside the multiple rows of horizontal brackets 64 through the multiple groups of water supply pipes 651.

[0097] Specifically, the booster pump 36 can extract the condensed water generated by the air compression collected inside the water storage tank 35, and inject the condensed water into the passage through the water supply pipe 651 to supply water to the atomizing nozzle 644 and the spray nozzle 6421. In this way, the condensed water generated by the air compression can be used as the water source of the atomizing nozzle 644 and the spray nozzle 6421, so that the water mist spraying before the pulse spraying and the flushing of the filter cartridge 62 after the dust collector is working can be realized without external water supply, so as to make full use of energy and save water resources.

[0098] like Figure 1 and Figure 2 As shown, the pulse jet assembly 70 includes an air supply pipe 71, multiple rows of pulse jet pipes 72 and an air distribution box 73. One end of the air supply pipe 71 is connected to the interior of the air distribution box 73, and the other end of the air supply pipe 71 is connected to the interior of the air storage tank 33. That is, the compressed air in the air storage tank 33 is dried by the compressed air dryer 34, filtered by the P-level filter 37 and the S-level filter 38, and reduced in pressure by the pressure reducing valve 39, and finally enters the interior of the air distribution box 73 through the air supply pipe 71.

[0099] A group of pulse blowing tubes 72 is installed above each row of filter cartridges 62 . The interiors of the multiple groups of pulse blowing tubes 72 are connected to the interior of the air distribution box 73 . The compressed air entering the air distribution box 73 can be distributed to the multiple groups of pulse blowing tubes 72 .

[0100] Pulse valves 721 are fixedly installed on multiple groups of pulse blowing tubes 72, and each group of pulse blowing tubes 72 is installed with a jet port corresponding to the air hole 611. Under the control of the pulse valve 721, the jet port on the pulse blowing tube 72 can spray compressed air into the inside of the filter cartridge 62 through the air hole 611, thereby realizing pulse back-blowing cleaning of the filter cartridge 62.

[0101] During use, when the material on the first belt 80 falls onto the second belt 90 , the generated dust will be adsorbed on the outer surface of the filter cartridge 62 , thereby achieving dust removal.

[0102] Before pulse-jetting the filter cartridge 62, start the booster pump 36, extract the condensed water in the water storage tank 35 through the booster pump 36, and then inject it into the passage inside each row of the horizontal bracket 64 through the water supply pipe 651, and finally spray water mist through the atomizing nozzle 644; at this time, the motor running wheel 661 moves inside the track groove 631, so that the horizontal bracket 64 first descends and then rises to reset. In this process, the dust particles on the outer surface of the filter cartridge 62 are combined into a cake shape by continuously spraying water mist; then, the filter cartridge 62 is cleaned by the pulse-jetting pipe 72. During pulse blowing, the transverse support 64 is caused to descend synchronously with the compressed gas, and the block materials formed by the cake-shaped rupture are blocked and limited, so that the block materials fall smoothly onto the second belt 90 and are transmitted backward with the materials; then, the transverse support 64 rises and resets. During this process, the blades 6451 can drive the rotating ring 645 to rotate with the help of wind force, so that the soft plate 6452 is deformed. At this time, the brush 6453 contacts the outer surface of the filter cartridge 62, so that during the rising process of the transverse support 64, the outer surface of the filter cartridge 62 is rotated and cleaned again to achieve further cleaning.

[0103] The conveyor circulation purification dust collector of the present invention adopts a highly integrated structure, and can achieve large-flow heat dissipation through the clean airflow chamber, ensuring stable and efficient operation of the whole machine, and can match the pressure for the oil-free air compressor 31, reducing the operating burden, which is conducive to extending its service life and reducing energy loss. At the same time, the filter component 60 can achieve full-automatic cleaning and achieve maintenance-free effect;

[0104] By spraying water mist onto the dust particles on the surface of the filter cartridge 62 before pulse spraying, and controlling the size of the water mist particles to accurately control the humidity of the material on the surface of the filter cartridge, the water mist is used to combine the dust particles with each other to form a cake, thereby avoiding dust generation again when back-blowing the filter cartridge 62, improving the environmental protection of the dust collector, and no longer needing to deal with secondary dust, greatly improving the working efficiency of the dust collector and saving costs;

[0105] By moving the horizontal bracket 64 synchronously with the pulse gas, the blown-off cake material can be blocked and collected, so that the cake material can fall smoothly onto the conveyor below, completing the conversion and recycling of the dust material and avoiding material waste;

[0106] Through the deep cleaning component, the filter cartridge 62 can be automatically rotated and cleaned after backwash cleaning during the resetting process of the transverse bracket 64, thereby effectively improving the cleaning effect of the filter cartridge 62 and improving the dust removal efficiency.
