Description

Technical Field

[0001] The present invention relates to the technical field of dust removal devices, and more specifically, it relates to a dust removal device for mining engineering. Background Art

[0002] Mining engineering is a systematic project. Its core lies in obtaining various mineral resources from underground or on the surface, and through further processing, transportation, and efficient utilization of these resources, realizing the transformation of resource value. In mining operations, dust removal devices, as key environmental protection equipment, mainly address the dust pollution problems generated in production links such as mining, crushing, and screening. These devices use technical means such as physical interception and electrostatic adsorption to control the diffusion of dust, not only reducing the pollution load on the atmospheric environment but also significantly improving the underground working environment, providing labor conditions that meet occupational health standards for miners, and thus achieving the dual goals of safe production and environmental protection while ensuring the efficiency of resource development.

[0003] Currently, the dust removal equipment applied to mining engineering generally adopts negative pressure suction technology. Through extracting the dust-containing gas at the operation site and passing it through a filtration system to achieve the technological process of dust interception and clean air discharge. However, during continuous operation, the continuous deposition of dust particles on the surface of the filter medium will gradually form a clogging layer, resulting in the blockage of the filtration channels, a significant increase in air flow resistance, and further leading to the technical bottleneck of the attenuation of dust removal efficiency. Traditional solutions rely on manual shutdown for disassembly and maintenance. This passive maintenance mode not only interrupts continuous production operations but also reduces the overall availability of the dust removal system due to long maintenance cycles and high labor intensity, forming a dual constraint on production efficiency and environmental protection benefits.

[0012] As a further optimization solution of the present invention, a receiving groove is provided on the shovel plate, and the receiving groove forms a right-angled trapezoidal opening on the extended side of the shovel plate.

[0013] As a further optimization scheme of the present invention, the driving member includes a driving motor, a driving gear and an inner gear ring. The driving motor is arranged on the connecting member, the inner gear ring is fixedly sleeved on the inner periphery of the annular filter screen, and the driving gear is fixedly sleeved on the driving shaft of the driving motor and cooperates with the inner gear ring for transmission.

[0014] As a further optimization scheme of the present invention, the connecting part includes a connecting pipe, a side arc plate and a bottom arc plate. The connecting pipe and the side arc plate are respectively fixedly mounted on the ends of the connecting pipe and are slidably connected to the inner circumference of the annular filter net. The connecting pipe is connected to the water treatment mechanism through a mounting frame. The connecting pipe is respectively connected to the side filter area and the bottom filter area, and the bottom arc plate is fixedly connected to the drive motor.

[0015] As a further optimization scheme of the present invention, the knocking mechanism includes a block, an elastic rope and a magnetic ball. The block is installed on the bottom arc plate and has a guide groove inside.

[0017] As a further optimized solution of the present invention, a net plate is fixedly installed inside the treatment tank, and the discharge pipe passes through the net plate.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. For the dust removal device for mining engineering described in the present invention, the filtering mechanism adopts the setting of alternating filtration and self-cleaning of multiple filtering areas, avoiding the problem of reduced dust removal efficiency caused by the blockage of a single filtering area. At the same time, the cooperation of the knocking mechanism and the scraping member can timely clean the dust on the filtering mechanism, ensuring the filtering effect and thus significantly improving the overall dust removal efficiency.

[0020] 2. For the dust removal device for mining engineering described in the present invention, through the automatic cleaning mechanism, including the reverse cleaning of the filtering area, the knocking and vibrating cleaning, and the cleaning of the air inlet and the exhaust end by the scraping member, the frequency of manual shutdown and disassembly for maintenance due to dust accumulation is reduced. This not only saves maintenance time and labor costs but also avoids the impact of shutdown on production operations, improving the overall usability of the equipment.

[0021] 3. For the dust removal device for mining engineering described in the present invention, the filtered air is subjected to secondary scrubbing treatment by the water treatment mechanism to further remove residual impurities. The setting of the net plate increases the contact effect between air and water, making the discharged air cleaner. When the air in contact with water is discharged, it has a certain humidity, so the humidity of the air in the area where the device is located can be increased at this time, thereby reducing the dryness of the air. On the one hand, it reduces the possibility of dust explosion, and on the other hand, it plays an auxiliary role in dust reduction. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Reference will now be made to example embodiments to discuss the subject matter described herein. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein, and changes can be made to the functions and arrangements of the elements discussed without departing from the scope of protection of the content of this specification. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described in some examples can be combined in other examples.

[0041] As Figure 1 and Figure 3 shown, a dust removal device for mining engineering according to an embodiment of the present invention is characterized by comprising: a dust suction mechanism 1, an annular shell 2, a filtering mechanism 3, a connecting member 4, a knocking mechanism 5, a water treatment mechanism 6, and a collection box 7;

[0042] The annular shell 2 is communicated with the dust suction mechanism 1. The filtering mechanism 3 has a plurality of filtering areas, and the filtering mechanism 3 is rotatably arranged in the annular shell 2 to filter the sucked gas.

[0043] The water treatment mechanism 6 is communicated with the annular shell 2.

[0044] The filtering mechanism 3 is in driving cooperation with a driving member. When the driving member drives the filtering mechanism 3 to rotate, the filtering mechanism 3 rotates and filters the air sucked by the dust suction mechanism 1. The connecting member 4 receives the filtered air, reversely cleans other filtering areas of the filtering mechanism 3, and then passes the air into the water treatment mechanism 6 for gas washing. At the same time, the filtering mechanism 3 intermittently attracts the knocking mechanism 5, and is cleaned by being impacted and vibrated by it, so that the dust particles are discharged into the collection box 7.

[0045] The collection box 7 is communicated with the annular shell 2 through a through port.

[0046] It should be noted that the dust suction mechanism 1 sucks the dust-containing air. The filtering mechanism 3 is rotatably arranged in the annular shell 2, and its multiple filtering areas can filter the air in sequence during the rotation process, avoiding affecting the dust removal efficiency due to the blockage of a single filtering area. The driving member drives the filtering mechanism 3 to rotate. While the filtering mechanism 3 rotates and filters, the connecting member 4 receives the filtered air and uses this part of the air to reversely clean other filtering areas, realizing the self-cleaning of the filtering areas. The knocking mechanism 5 cooperates with the filtering mechanism 3. The filtering mechanism 3 intermittently attracts the knocking mechanism 5, and the knocking mechanism 5 impacts the filtering mechanism 3 to make it vibrate, shaking off the attached dust particles. The water treatment mechanism 6 further performs gas washing treatment on the filtered air to remove residual impurities. The collection box 7 is used to collect the dust particles scattered from the filtering mechanism 3, so as to realize the continuous filtering and automatic cleaning of the dust-containing air, without frequent shutdown for maintenance, improving the dust removal efficiency and reducing the environmental pollution caused by dust.

[0047] As Figure 2 and Figure 3As shown in the figure, the dust suction mechanism 1 includes a suction hopper 101 and a suction fan 102. An air inlet 201 is provided on the annular shell 2. The exhaust end of the suction hopper 101 is communicated with the air inlet 201, and the suction fan 102 is arranged inside the suction hopper 101.

[0048] As the starting link, the dust suction mechanism 1, with its suction hopper 101 and suction fan 102 cooperating with each other, provides power for the dusty air to enter the subsequent filtration and treatment links.

[0049] As Figures 2 to 4 shown in the figure, the filtration mechanism 3 includes an annular filter screen 31, a partition block 32 and a magnetic block 33. The annular filter screen 31 is divided into multiple filtration areas by the partition block 32. The magnetic block 33 is embedded in the partition block 32, and a scraping member for cleaning the exhaust end of the suction hopper 101 and the air inlet 201 is arranged inside the partition block 32.

[0050] It should be noted that the annular filter screen 31 is used to intercept dust particles in the dusty air. The partition block 32 divides the annular filter screen 31 into multiple filtration areas, enabling the filtration process to proceed alternately. When some areas are in the filtration state, the remaining areas can carry out the cleaning work in sequence, improving the filtration efficiency and ensuring the continuity and stability of filtration. The magnetic block 33 embedded in the partition block 32 cooperates with the knocking mechanism 5. Using the principle of magnetic attraction, it prompts the knocking mechanism 5 to impact and vibrate the filtration area, further enhancing the cleaning effect. In addition, the scraping member inside the partition block 32 plays a role during the rotation of the filtration mechanism 3 to clean the dust accumulated at the exhaust end of the suction hopper 101 and the air inlet 201, effectively preventing dust accumulation from hindering the air flow and ensuring the unobstructed intake passage.

[0051] As Figure 5 shown in the figure, the scraping member includes a return spring 34 and a scraping plate 35. A chute 321 is provided inside the partition block 32. The scraping plate 35 is slidably sleeved inside the chute 321 and is connected to the inner wall of the chute 321 through the return spring 34.

[0052] It should be noted that one end of the return spring 34 is connected to the inner wall of the chute 321, and the other end is connected to the shovel plate 35, providing elastic force for the shovel plate 35. When the filtering mechanism 3 rotates, the shovel plate 35 slides in the chute 321 under the combined action of centrifugal force and the return spring 34. During this process, when the shovel plate 35 extends, it can remove and clean the dust accumulated at the exhaust end of the suction hopper 101 and the air inlet 201. As the annular filter net 31 rotates, the shovel plate 35 is squeezed back into the chute 321 by the ring shell 2, compressing the return spring 34 to store energy, waiting for the next cleaning operation. During the working process of the entire device, the return spring 34 and the shovel plate 35 regularly clean the dust at the exhaust end of the suction hopper 101 and the air inlet 201 when the filtering mechanism 3 rotates, ensuring the smooth entry of dusty air into the filtering area, which plays an important role in maintaining the normal operation of the device.

[0053] Further, a receiving groove 351 is formed on the shovel plate 35, and the receiving groove 351 forms a right trapezoidal opening 3511 on the extending side of the shovel plate 35.

[0054] It should be noted that when the filtering mechanism 3 rotates to drive the shovel plate 35 to clean the dust at the exhaust end of the suction hopper 101 and the air inlet 201, the right trapezoidal opening 3511 can better accommodate and collect dust due to its shape, guiding the dust to smoothly enter the receiving groove 351, thereby improving the dust cleaning efficiency.

[0055] As Figures 2 to 3 shown, the driving member includes a driving motor 8, a driving gear 9 and an internal gear ring 10. The driving motor 8 is arranged on the connecting member 4, the internal gear ring 10 is fixedly sleeved on the inner circumference of the annular filter net 31, and the driving gear 9 is fixedly sleeved on the driving shaft of the driving motor 8 and is in transmission cooperation with the internal gear ring 10.

[0056] It should be noted that the driving motor 8 drives the driving gear 9 to rotate. The driving gear 9 meshes with the internal gear ring 10 fixedly sleeved on the inner circumference of the annular filter net 31, thereby transmitting the rotational power of the driving motor 8 to the annular filter net 31, causing the annular filter net 31 to rotate, and further realizing the rotation of the filtering mechanism 3, driving multiple filtering areas to perform filtering and cleaning operations in sequence.

[0057] As Figures 1 to 4 shown, the connecting member 4 includes a connecting pipe 41, a side arc plate 42 and a bottom arc plate 43. The connecting pipe 41 and the side arc plate 42 are respectively fixedly sleeved at the end of the connecting pipe 41 and are slidably connected to the inner circumference of the annular filter net 31. The connecting pipe 41 is connected to the water treatment mechanism 6 through a mounting frame. The connecting pipe 41 communicates with the side filtering area and the bottom filtering area respectively, and the bottom arc plate 43 is fixedly connected to the driving motor 8.

[0058] It should be noted that the connecting pipe 41 of the connecting member 4 plays a role in reversely cleaning the filtering area by using the filtered air, ensuring that the filtered air can smoothly enter the water treatment mechanism 6 for subsequent treatment. The connecting pipe 41 is respectively connected to the filtering areas on the side and the bottom, responsible for collecting the filtered air, tightly connecting the filtering mechanism 3 and the water treatment mechanism 6, and transporting the filtered air to the water treatment mechanism 6. At the same time, in cooperation with the rotation of the filtering mechanism 3, each link of filtering, cleaning, and gas transportation can be carried out in coordination, jointly ensuring the efficient development of the dust removal work.

[0059] As Figures 2 to 4 and Figure 7 shown, the knocking mechanism 5 includes a block 51, an elastic rope 52, and a magnetic ball 53. The block 51 is installed on the bottom arc plate 43, and a guide groove 511 is opened inside. The magnetic ball 53 is connected to the inside of the guide groove 511 through the elastic rope 52. The magnetism of the magnetic ball 53 is opposite to that of the magnetic block 33. The outer periphery of the magnetic ball 53 is wrapped with an elastic layer, and the elastic layer is a rubber elastic layer or a silica gel elastic layer.

[0060] It should be noted that the magnetic ball 53 is connected in the guide groove 511 inside the block 51 by means of the elastic rope 52. When the filtering mechanism 3 rotates and the magnetic block 33 on it approaches the magnetic ball 53, due to the opposite magnetism of the two, the magnetic ball 53 is attracted and stretches the elastic rope 52 to move towards the magnetic block 33. When the magnetic block 33 rotates away, the magnetic ball 53 impacts the block 51 and rebounds under the elastic force of the elastic rope 52, thereby generating an impact vibration on the filtering mechanism 3, prompting the dust particles attached to the filtering area at the annular filter net 31 to fall off. The elastic layer wrapped around the outer periphery of the magnetic ball 53 can not only reduce the wear between itself and the filtering mechanism 3 during impact but also avoid damaging the filtering mechanism 3. Through the coordinated cooperation of magnetic attraction and the elastic rope 52, automatic cleaning of the filtering mechanism 3 is achieved, effectively improving the filtering effect. When the filtering mechanism 3 rotates, the knocking mechanism 5 interacts with the magnetic block 33, and the dust particles fall off into the collection box 7 through impact vibration, assisting the filtering mechanism 3 to clean itself, strongly ensuring the filtering performance of the filtering mechanism 3, and ensuring the efficient operation of the entire dust removal device.

[0061] As Figures 2 to 4 and Figure 6As shown in the figure, the water treatment mechanism 6 includes a treatment tank 61, a rotating rod 62, a stirring blade 63, a guide rod 64, a rack 65, a reciprocating spring 66, a transmission gear 67, a magnet 68 and a discharge pipe 69. The treatment tank 61 is installed at the bottom of the collection box 7 and is fixedly connected to the connecting pipe 41 through a mounting bracket. The rotating rod 62 is rotatably arranged inside the treatment tank 61. The stirring blade 63 is installed on the outer periphery of the rotating rod 62. One end of the guide rod 64 slides out of the treatment tank 61 and is fixedly sleeved with the magnet 68. The magnet 68 has the opposite magnetism to the magnetic block 33. The other end of the guide rod 64 is connected to the inner bottom wall of the treatment tank 61 through the reciprocating spring 66. The rack 65 is fixedly installed on the guide rod 64. The transmission gear 67 is fixedly sleeved on the rotating rod 62 and is in transmission cooperation with the rack 65. One end of the discharge pipe 69 is communicated with the bottom of the annular shell 2, and the other end extends into the interior of the treatment tank 61. The interior of the treatment tank 61 is filled with liquid water, and the liquid water level submerges the exhaust end of the discharge pipe 69. A discharge hole is formed on one side of the treatment tank 61 to discharge the air after suction.

[0062] The treatment tank 61 contains water for gas washing. The rotating rod 62 rotates inside the treatment tank 61, driving the stirring blade 63 on the outer periphery to rotate. One end of the guide rod 64 is connected to the inner bottom wall of the treatment tank 61 through the reciprocating spring 66, and the other end slides out of the treatment tank 61 and is fixedly sleeved with the magnet 68. When the magnetic block 33 on the filtering mechanism 3 rotates close to the magnet 68, the magnet 68 is attracted to drive the guide rod 64 to move upward and stretch the reciprocating spring 66. After the magnetic block 33 leaves, the guide rod 64 moves downward under the action of the spring force. The rack 65 fixed on the guide rod 64 meshes with the transmission gear 67 on the rotating rod 62. The up and down movement of the guide rod 64 drives the rack 65, and then the transmission gear 67 drives the rotating rod 62 and the stirring blade 63 to rotate reciprocally. The rotation of the stirring blade 63 makes the water in the treatment tank 61 flow, performs gas washing treatment on the filtered air entering through the discharge pipe 69, removes residual impurities, and the air after gas washing is discharged through the discharge hole, further purifying the air and reducing environmental pollution.

[0063] Further, a mesh plate 610 is fixedly installed inside the treatment tank 61, and the discharge pipe 69 passes through the mesh plate 610.

[0064] Under the action of the mesh plate 610, the air discharged from the discharge pipe 69 is evenly dispersed and blocked, increasing the contact effect between the air and the liquid water.

[0065] Working principle:

[0066] Dust collection stage: The dust collection mechanism 1 is the starting link. The exhaust fan 102 inside it is powered on and operates to generate suction. Under the action of the exhaust fan 102, the suction hopper 101 collects the dust-containing air at the mining operation site and conveys it to the air inlet 201 of the annular shell 2 through the exhaust end, so that the dust-containing air enters the annular shell 2.

[0067] Filtering and self-cleaning stage: After the dusty air enters the annular housing 2, the drive motor 8 starts, driving the drive gear 9 to rotate. The drive gear 9 meshes with the internal gear ring 10 fixedly sleeved on the inner circumference of the annular filter net 31, transmitting power to the annular filter net 31 and causing it to rotate around its own central axis. The annular filter net 31 is divided into multiple filter areas by the partition blocks 32. During rotation, these filter areas sequentially filter the dusty air.

[0068] During the filtering process, the connecting member 4 plays a role. The connecting pipe 41 is connected to the side and bottom filter areas of the annular filter net 31, receiving the filtered air. The filtered air acts on the bottom filter area for cleaning. At the same time, the magnetic blocks 33 embedded in the partition blocks 32 on the filter mechanism 3 rotate with the filter mechanism 3. When the magnetic block 33 approaches the magnetic ball 53 of the knocking mechanism 5, due to the opposite magnetism of the two, the magnetic ball 53 is attracted to stretch the elastic rope 52 and move towards the magnetic block 33. After the magnetic block 33 leaves, the magnetic ball 53 impacts the block 51 and rebounds under the elastic force of the elastic rope 52, generating an impact vibration on the filter mechanism 3, causing the dust particles attached to the annular filter net 31 to fall off and into the collection box 7, realizing the automatic cleaning of the filter mechanism 3.

[0069] In addition, the scraping member inside the partition block 32 also plays a role when the filter mechanism 3 rotates. The scraping plate 35 slides in the chute 321 under the combined action of centrifugal force and the return spring 34. When the scraping plate 35 extends, it can scrape and clean the dust accumulated at the exhaust end of the air suction hopper 101 and the air inlet 201. The right-angled trapezoidal opening 3511 provided on the scraping plate 35 can better accommodate and collect dust, improving the cleaning efficiency. After the cleaning is completed, the scraping plate 35 retracts under the action of the return spring 34, waiting for the next cleaning. When the scraping plate 35 rotates to the collection box 7, it is affected by vibration and inclination to discharge the dust.

[0070] Water treatment stage: The filtered air acts on the annular filter screen 31 in the reverse direction through the connecting pipe 41, and back blows the annular filter screen 31. At this time, the air enters the inside of the ring shell 2 and enters the treatment tank 61 through the discharge pipe 69. There is water in the treatment tank 61. The rotating rod 62 rotates in the treatment tank 61, driving the stirring blades 63 installed on its outer circumference to rotate. When the magnet 33 on the filtering mechanism 3 rotates close to the magnet 68, the magnet 68 is attracted and drives the guide rod 64 to move upward, stretching the reciprocating spring 66. After the magnet 33 leaves, the guide rod 64 moves downward under the elastic force of the reciprocating spring 66. The rack 65 fixed on the guide rod 64 meshes with the transmission gear 67 fixedly sleeved on the rotating rod 62. The up and down movement of the guide rod 64 drives the rack 65 to move, and then the transmission gear 67 drives the rotating rod 62 and the stirring blades 63 to rotate reciprocally. The rotation of the stirring blades 63 makes the water in the treatment tank 61 flow, performs air washing treatment on the filtered air entering the treatment tank 61, removes residual impurities, and increases the air washing effect. The net plate 610 fixedly installed inside the treatment tank 61 plays a role in evenly dispersing and blocking the air discharged from the discharge pipe 69, increases the contact effect between the air and the water, further purifies the air, and the purified air is discharged through the discharge hole on one side of the treatment tank 61.

[0071] The embodiments of the present invention have been described above, but the present embodiment is not limited to the above specific implementation manners. The above specific implementation manners are only illustrative and not restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
