Description

Technical Field

[0001] The invention relates to the technical field of concrete processing, in particular to a dispersed dust removal device for concrete processing. Background Art

[0002] The main raw materials of concrete include cement, sand, aggregates (such as crushed stone, pebbles, etc.) and water. Cement, as a cementing material, can bond other materials together. Sand and aggregates are used as filling materials to increase the strength and stability of concrete. Cement, sand, aggregates and water are mixed together manually or mechanically. In order to avoid environmental pollution caused by floating dust during the concrete processing, the dust needs to be treated through a dust removal device.

[0003] For example, the patent number published on the China Patent Network is: 202220319406.6, and the patent name is: A dust removal device for concrete processing, including a horizontal slide, a vertical slide, a dust removal mechanism and a lifting mechanism, wherein the two ends of the horizontal slide are fixedly connected to the ground through a stand, and the vertical slide is slidably mounted on the horizontal slide and can slide along the horizontal slide, the dust removal mechanism is slidably mounted on the vertical slide, and the lifting mechanism is used to drive the dust removal mechanism to slide along the vertical slide. The dust removal device for concrete processing is convenient for adjusting the dust removal coverage area according to the dust position and dust range, so as to effectively remove dust from the processing area during the concrete processing process.

[0004] However, the existing dust removal device mainly adjusts the dust removal position by expanding the horizontal guide rail, and the concrete dust diffuses around the processing point as the axis during the diffusion process. The dust collection method of a single unit will cause some dust to not be effectively sucked away, affecting the cleanliness of the working environment.

[0005] Secondly, a single fan is installed on the surface of the dust removal device to guide the airflow. An electric drive structure needs to be set up during the operation of the fan. The drive structure will generate a lot of heat after continuous operation and consume a lot of energy, which greatly increases the use cost of the dust removal device.

[0006] In addition, the dust removal device can only filter and collect dust. The dust accumulated inside the equipment will float again during the cleaning process due to the structural characteristics of the powder, which greatly increases the cleaning difficulty for users and causes secondary pollution to the working environment.

[0007] Therefore, it is necessary to design and transform the decentralized dust removal device for concrete processing. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention collects external dust through the dust collecting structure and injects it into the filter component for filtration, which can greatly reduce the dust diffusion and improve the cleanliness of the working environment. At the same time, the dust collecting structure driven by the transmission structure can greatly expand the collection range, so that it can guide the airflow during the rotation process, so that the surrounding airflow forms a vortex to avoid airflow diffusion. At the same time, the linkage structure can drive the dust collecting structure to operate during the rotation process, saving the user the operating steps of additionally setting up the driving device.

[0020] 2. The present invention provides a rotatable drum connected to the top of the collecting drum, which can transmit power during the rotation process. At the same time, the vibration force generated during the rotation process can vibrate and clean the filter plate, reduce the amount of dust sticking to the surface of the filter plate, and avoid clogging of the filter plate.

[0021] 3. The present invention uses a support on the surface of the rotating drum to drive the impeller and the fan casing to rotate synchronously. The impeller pressurizes the airflow inside the fan casing, so that the fan casing collects concrete dust floating in the external environment through the opening on the surface and pressurizes it to the inside of the rotating drum through a conveying pipe. It can effectively absorb the external airflow and avoid airflow diffusion, while achieving the effect of circling the surrounding of the collecting cylinder.

[0022] 4. In the present invention, during the rotation of the drum, the gear at the bottom of the bracket contacts the gear ring and uses the meshing force to push the driven wheel to rotate.

[0023] 5. The present invention can simultaneously drive the rotating drum and the conveying rod to rotate by providing a dual-axis motor, so that the number of rotations of the two remains consistent, thus saving the operation steps of additionally providing a driving device.

[0024] 6. The present invention can use the limit plate to drive the screw sleeve to rotate synchronously through the sleeve on the top of the filter plate. During the rotation process, the screw sleeve uses the surface thread to reciprocate on the surface of the reciprocating screw. During the movement, the screw sleeve drives the linkage plate to slide on the inner side of the sleeve plate. At the same time, the sliding rod on the surface of the linkage plate can squeeze the sleeve plate, so that the fan casing connected to the sleeve plate rotates and swings around the impeller on the inner side of the bracket, thereby changing the collection angle of the fan casing, increasing the collection range, and meeting the use requirements of different environments.

[0025] 7. The present invention accumulates dust on the surface of the inner carrier plate at the contraction position and expands the accumulation area during the continuous conveying process of the conveying rod. The dust can squeeze the carrier plate during the continuous conveying process, causing the carrier plate to move downward and squeeze the compression spring to contract. When the contact time between the bottom of the carrier plate and the top of the push switch exceeds a preset value, a prompt message can be provided to the user, so that the user can respond to maintenance in a timely manner.

[0026] 8. The present invention provides a sealing door, which makes it easier for users to clean the inside of the collection tube and reduces the difficulty of operating the collection tube. BRIEF DESCRIPTION OF THE DRAWINGS

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 are within the scope of protection of the present invention.

[0037] like Figures 1 to 8 As shown, the present invention provides a dispersed dust removal device for concrete processing, comprising a filter assembly 1;

[0038] A dust collecting structure 2 is provided on the outside of the filter component 1. The dust collecting structure 2 can collect the airflow on the outside of the filter component 1 and transport it to the inside of the filter component 1 for filtration. A transmission structure 3 is provided inside the filter component 1. The transmission structure 3 can drive the dust collecting structure 2 to rotate and increase the collection range.

An adjustment structure 5 is provided on the top of the filter component 1. The adjustment structure 5 can adjust the dust collection angle during the rotation of the dust collecting structure 2.

When working, the rotating cylinder 7 and the collecting cylinder 6 are connected by a bearing, and an additional movable oil seal is arranged at the connection between the rotating cylinder 7 and the collecting cylinder 6 to reduce the gap between the rotating cylinder 7 and the collecting cylinder 6 to avoid dust leakage. At the same time, the pore size of the filter plate 8 is 3-5 microns, and the filter plate 8 is composed of multiple layers of filter screens stacked on each other.

[0040] As a technical optimization solution of the present invention, by setting a rotatable drum 7 connected to the top of the collecting drum 6, power can be transmitted during the rotation process. At the same time, the vibration force generated during the rotation process can vibrate and clean the filter plate 8, thereby reducing the amount of dust sticking to the surface of the filter plate 8 and avoiding clogging of the filter plate 8.

[0041] refer to Figure 4 The dust collecting structure 2 includes a bracket 9 fixedly connected to the surface of the drum 7, the inner side of the bracket 9 is movably connected to the impeller 10 through a bearing, and a fan casing 11 is provided on the inner side of the bracket 9 and is sleeved on the surface of the impeller 10. The fan casing 11 can rotate and swing on the surface of the impeller 10. The surface of the fan casing 11 is connected with a conveying pipe 12, and the side of the conveying pipe 12 away from the fan casing 11 is connected to the surface of the drum 7. The drum 7 can drive the fan casing 11 to rotate through the bracket 9, and the linkage structure 4 can drive the impeller 10 during the rotation of the drum 7. During operation, the fan casing 11 and the impeller 10 are movably connected through the bearing. During the rotation of the impeller 10, the fan casing 11 is limited by the adjustment structure 5 to remain stationary or swing.

[0042] As a technical optimization scheme of the present invention, the impeller 10 and the fan casing 11 are driven to rotate synchronously by the bracket 9 on the surface of the rotating drum 7. The impeller 10 pressurizes the airflow inside the fan casing 11, so that the fan casing 11 collects the concrete dust floating in the external environment through the opening on the surface and pressurizes it to the inside of the rotating drum 7 by the conveying pipe 12. It can effectively absorb the external airflow and avoid airflow diffusion, while achieving the effect of circling around the collecting cylinder 6.

[0043] refer to Figure 3The linkage structure 4 includes a gear ring 13 fixedly connected to the surface of the collecting cylinder 6, a connecting plate 14 is fixedly connected to the bottom of the bracket 9, and a transmission rod 15 is movably connected to the inside of the connecting plate 14 through a bearing. The end of the impeller 10 located on the outer side of the bracket 9 and the surface of the transmission rod 15 are fixedly connected with a pulley 16, and a belt 17 is sleeved on the surface of the pulley 16. The end of the transmission rod 15 away from the pulley 16 is fixedly connected with a driven wheel 18, and the surface of the connecting plate 14 is movably connected with a gear 19 located on one side of the driven wheel 18 through a bearing. The gear 19 is meshed with the driven wheel 18 and the gear ring 13 respectively. The transmission ratio of the impeller 10 located at one end of the outer side of the bracket 9 and the pulley 16 on the surface of the transmission rod 15 is two to one. When the pulley 16 on the surface of the transmission rod 15 rotates one circle, the pulley 16 on the surface of the impeller 10 rotates two circles. The transmission ratio between the gear 19 and the driven wheel 18 is one to three. When the gear 19 rotates one circle, the driven wheel 18 rotates three circles.

[0044] As a technical optimization solution of the present invention, during the rotation of the drum 7, the gear 19 at the bottom of the bracket 9 contacts the gear ring 13 and uses the meshing force to push the driven wheel 18 to rotate. The driven wheel 18 drives the pulley 16 on the surface of the bracket 9 to rotate. The pulley 16 drives the impeller 10 to rotate using the belt 17. It can automatically drive multiple impellers 10 to rotate, thereby greatly improving the energy-saving effect of the structure.

[0045] refer to Figure 6 The transmission structure 3 includes a frame 20 fixedly connected to the inside of the collecting cylinder 6, and a dual-axis motor 21 is fixedly connected to the inside of the frame 20. The output end of the top of the dual-axis motor 21 is fixedly connected to the surface of the filter plate 8. The dual-axis motor 21 can use the filter plate 8 to drive the rotating cylinder 7 to rotate.

[0046] As a technical optimization solution of the present invention, by setting up a dual-axis motor 21, it is possible to drive the rotating drum 7 and the conveying rod 31 to rotate at the same time, so that the number of rotations of the two remains consistent, saving the operating steps of setting up additional driving equipment.

[0047] refer to Figure 8The adjusting structure 5 includes a sleeve plate 22 fixedly connected to the surface of the fan housing 11, a column 23 fixedly connected to the surface of the collecting cylinder 6, the column 23 extends to the top of the rotating cylinder 7 away from the side of the collecting cylinder 6, a reciprocating screw 24 fixedly connected to the bottom of the column 23, a sleeve 25 sleeved on the surface of the reciprocating screw 24 fixedly connected to the top of the filter plate 8, the sleeve 25 and the reciprocating screw 24 are movably connected through a bearing, a screw sleeve 26 is threadedly connected to the surface of the reciprocating screw 24, and a screw sleeve 26 is fixedly connected to the surface of the screw sleeve The linkage plate 27 is located on the inner side of the sleeve plate 22. The surface of the linkage plate 27 is fixedly connected with a slide bar 28 located inside the sleeve plate 22. The slide bar 28 is slidably connected to the sleeve plate 22. The surface of the sleeve 25 is fixedly connected with a limit plate 29. The outer surface of the screw sleeve 26 is fixedly connected with a limit rod 30 located inside the limit plate 29. The limit rod 30 is slidably connected to the limit plate 29. When working, the movement distance of the screw sleeve 26 on the surface of the reciprocating screw 24 is controlled according to the swing angle requirement of the fan casing 11.

[0048] As a technical optimization scheme of the present invention, the sleeve 25 on the top of the filter plate 8 can use the limit plate 29 to drive the screw sleeve 26 to rotate synchronously. During the rotation process, the screw sleeve 26 uses the surface thread to reciprocate on the surface of the reciprocating screw 24. During the movement, the screw sleeve 26 drives the linkage plate 27 to slide on the inner side of the sleeve plate 22. At the same time, the sliding rod 28 on the surface of the linkage plate 27 can squeeze the sleeve plate 22, so that the fan casing 11 connected to the sleeve plate 22 rotates and swings around the impeller 10 on the inner side of the bracket 9, thereby changing the collection angle of the fan casing 11, improving the collection range, and meeting the use requirements of different environments.

[0049] refer to Figure 6The output end at the bottom of the dual-axis motor 21 is fixedly connected to a conveying rod 31. The bottom of the collecting barrel 6 reduces the bottom diameter through a conical transition. The end of the conveying rod 31 away from the dual-axis motor 21 extends to the inside of the contraction of the bottom of the collecting barrel 6 and contacts the inner surface of the collecting barrel 6. The bottom of the inner wall of the collecting barrel 6 is fixedly connected to a pressing switch 32. The bottom of the inner wall of the collecting barrel 6 is fixedly connected to a compression spring 33 sleeved on the surface of the pressing switch 32. The top of the compression spring 33 is fixedly connected to a bearing plate 34 slidably connected to the inside of the collecting barrel 6. When working, the dust filtered and retained in the rotating drum 7 falls into the inside of the collecting barrel 6 and slides on the inclined surface of the inner wall of the collecting barrel 6 under the influence of the rotation and vibration of the rotating drum 7. When the dust and the conveying rod 31 are in contact with each other, the dust will be discharged to the collecting barrel 6. When the rod 31 contacts, the conveying rod 31 spirally conveys the dust, so that the dust enters the contraction part at the bottom of the collecting tube 6 for storage. The dust cannot exert pressure on the supporting plate 34 before it is stored to a certain thickness. When the dust accumulates to a certain amount and the top contacts the lowest end of the conveying rod 31, the continuously conveyed dust can squeeze the dust on the surface of the supporting plate 34, so that the dust is compressed on the surface of the supporting plate 34 and squeezes the supporting plate 34 to move downward. When the bottom of the supporting plate 34 contacts the surface of the press switch 32, it means that the amount of dust between the supporting plate 34 and the conveying rod 31 is close to the maximum value, and the rotating conveying rod 31 will continue to convey the dust to compress the dust between the supporting plate 34 and the conveying rod 31.

[0050] As a technical optimization scheme of the present invention, dust is accumulated on the surface of the internal supporting plate 34 at the contraction position and the accumulation area is expanded during the continuous conveying process of the conveying rod 31. The dust can squeeze the supporting plate 34 during the continuous conveying process, so that the supporting plate 34 moves downward and squeezes the compression spring 33 to contract. When the contact time between the bottom of the supporting plate 34 and the top of the push switch 32 exceeds the preset value, a prompt message can be provided to the user, so that the user can respond to maintenance in time.

[0051] refer to Figure 6 The surface of the collecting cylinder 6 is connected to a sealing door 35, which is located on the front of the supporting plate 34. The inner wall of the sealing door 35 fits the inner wall of the collecting cylinder 6 to prevent dust from flowing through the gap between the sealing door 35 and the supporting plate 34 to the vicinity of the push switch 32.

[0052] As a technical optimization solution of the present invention, by providing a sealing door 35 , it is convenient for the user to clean the inside of the collection tube 6 , thereby reducing the difficulty of operating the collection tube 6 .

[0053] The working principle and use process of the present invention are as follows: when in use, the filter assembly 1 is set at the concrete processing place and the dual-axis motor 21 is started during the concrete processing process. The output end at the top of the dual-axis motor 21 drives the drum 7 to rotate by using the filter plate 8. The drum 7 drives the impeller 10 and the fan housing 11 to rotate synchronously by using the bracket 9 on the surface. During the rotation of the drum 7, the gear 19 at the bottom of the bracket 9 contacts the gear ring 13 and uses the meshing force to drive the driven wheel 18 to rotate. The driven wheel 18 drives the pulley 16 on the surface of the bracket 9 to rotate. The pulley 16 drives the impeller 10 to rotate by using the belt 17. The impeller 10 rotates the inside of the fan housing 11. The airflow is pressurized, so that the fan housing 11 collects the concrete dust floating in the external environment through the opening on the surface and conveys it to the inside of the drum 7 under pressure through the conveying pipe 12. After the airflow containing concrete dust enters the drum 7, the air pressure inside the drum 7 is increased. The air pressure inside the drum 7 is expanded to discharge the airflow through the top filter plate 8 to the external environment. The filter plate 8 can filter the passing airflow, so that the concrete dust is retained in the drum 7 or precipitated in the collecting drum 6. During the rotation of the drum 7, the sleeve 25 on the top of the filter plate 8 can use the limit plate 29 to drive the screw sleeve 26 to rotate synchronously, and the screw sleeve 26 is rotated synchronously. The sleeve 26 reciprocates on the surface of the reciprocating screw 24 using the threads on its surface during the rotation process. The screw sleeve 26 drives the linkage plate 27 to slide on the inner side of the sleeve plate 22 during the movement. At the same time, the sliding rod 28 on the surface of the linkage plate 27 can squeeze the sleeve plate 22, so that the fan housing 11 connected to the sleeve plate 22 rotates and swings around the impeller 10 on the inner side of the bracket 9, changing the collection angle of the fan housing 11. During the rotation of the dual-axis motor 21, the output end at the bottom of the dual-axis motor 21 can drive the conveying rod 31 to rotate. The conveying rod 31 spirally rotates and conveys the dust deposited inside the collecting barrel 6 to enter the collecting barrel. At the contraction point at the bottom of the cylinder 6, the dust accumulates on the surface of the inner supporting plate 34 at the contraction point and the accumulation area is expanded during the continuous conveying process of the conveying rod 31. The dust can squeeze the supporting plate 34 during the continuous conveying process, so that the supporting plate 34 moves downward and squeezes the compression spring 33. The compression spring 33 stores the deformation force and uses the elastic conveying rod 31 to squeeze the dust, so that the dust increases the connection tightness between the supporting plate 34 and the conveying rod 31. When the contact time between the bottom of the supporting plate 34 and the top of the push switch 32 exceeds the preset value, the user opens the sealing door 35 to take out the extruded concrete dust block for continuous processing.

[0054] To sum up: the decentralized dust removal device for concrete processing collects external dust through the dust collecting structure 2 and injects it into the filter component 1 for filtration, which can greatly reduce the dust diffusion and improve the cleanliness of the working environment. At the same time, the dust collecting structure 2 driven by the transmission structure 3 can greatly expand the collection range, so that it can guide the airflow during the rotation process, so that the surrounding airflow forms a vortex to avoid airflow diffusion. At the same time, the linkage structure 4 can drive the dust collecting structure 2 to operate during the rotation process, saving the user the operating steps of setting up additional driving equipment.
