Description

Technical Field

[0001] This application relates to the field of concrete dust removal technology, and more particularly to a dust removal device for a concrete production line. Background Technology

[0002] Concrete is an essential material in modern construction, and therefore has a huge market demand. However, during its production process, the conveying and mixing of various materials inevitably generates a large amount of dust, especially in dry environments where dust dispersion is particularly noticeable. Therefore, in order to ensure the health of on-site production personnel and prevent them from contracting occupational diseases such as respiratory infections and pneumoconiosis, multiple dust removal devices are usually installed on the production line to minimize dust dispersion.

[0003] Currently, concrete production lines generally use water atomization to combine with dust and cause it to settle. However, this method is not very effective for small dust particles. While cyclone dust collectors use centrifugal force generated by rotating airflow to separate dust from the airflow, their dust removal efficiency is still insufficient to meet current environmental protection requirements for dust particles smaller than 5 micrometers. In addition, existing dust removal devices are generally bulky, inevitably occupying a lot of production space. Their large size also makes installation and maintenance complex, requiring professional technicians to operate, which increases production costs. Utility Model Content

[0004] To overcome the above deficiencies, this application provides a dust removal device for a concrete production line, which aims to improve the problem that the existing technology is unable to meet the standard requirements for cleaning small particulate dust.

[0005] To achieve the above objectives, this application adopts the following technical solution: a dust removal device for a concrete production line, including a shell, a dust removal mechanism in the middle of the shell, a dust discharge mechanism in the lower part of the shell, and a fan in the top of the shell;

[0006] The dust removal mechanism includes a rotating shaft, a mounting frame fixedly connected to the outside of the rotating shaft, multiple filter plates fixedly connected inside the mounting frame, an L-shaped plate below the mounting frame, an ultrasonic generator fixedly connected to the rear end of the L-shaped plate, a baffle plate slidably connected to the top of the mounting frame, one end of the rotating shaft passing through the outer shell and fixedly connected to a fan blade, a hollow disc slidably connected to the outside of the fan blade, the upper rear side of the hollow disc communicating with the outer shell through a pipe, and the bottom of the hollow disc communicating with the outer shell through a pipe.

[0007] As a further description of the above technical solution:

[0008] The ash removal mechanism includes a hydraulic rod, the top end of which is fixedly connected to the bottom end of an L-shaped plate, and a pressure block is fixedly connected to the output end of the hydraulic rod. A funnel is fixedly connected to the bottom of the outer shell, and a base plate is slidably connected to the bottom of the funnel.

[0009] As a further description of the above technical solution:

[0010] The two ends of the L-shaped plate are fixedly connected to the two sides inside the outer shell, and the front end of the L-shaped plate is fixedly connected to the front end inside the outer shell.

[0011] As a further description of the above technical solution:

[0012] One end of the baffle is fixedly connected to both sides inside the outer shell, and the rear end of the baffle is fixedly connected to the rear end inside the outer shell.

[0013] As a further description of the above technical solution:

[0014] The hollow disc is fixedly connected to the middle of one side of the outer shell near the mounting bracket. A bracket is provided on one outer side of the pipe. The bracket is fixedly connected to the rear of one side of the outer shell near the mounting bracket. A front cover is hinged to the front of the outer shell.

[0015] As a further description of the above technical solution:

[0016] Both ends of the rotating shaft are rotatably connected to the inside of the housing. Multiple scrapers are slidably connected to the outside of the mounting bracket. Both ends of the mounting bracket are rotatably connected to the inside of the housing.

[0017] As a further description of the above technical solution:

[0018] A frustum is fixedly connected to the outer side of the output end of the hydraulic rod, and the bottom end of the frustum is fixedly connected to the outer side of the top of the pressure block.

[0019] As a further description of the above technical solution:

[0020] A second baffle is provided above the funnel, and the outer side of the second baffle is fixedly connected to the lower part of the inner side of the outer shell.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. In this application, the dust removal mechanism allows the filter plates to be immersed in water one by one, so that the filter plates are actively cleaned under the action of the ultrasonic generator. This prevents a large amount of dust from adhering to the surface of the filter plates after long-term use, which would affect air circulation and filtration effect. At the same time, as air passes through the filter plates, the water remaining on the surface of the filter plates can increase their water molecule content, thereby further improving their dust settling effect. In addition, using water flow to drive the rotating shaft and mounting bracket to move the filter plates into the water one by one can avoid the damage to the structure caused by the ultrasonic generator when driven by the motor, so as to ensure the stability of the dust removal effect and prevent excessive dust accumulation due to component damage, thereby avoiding affecting the normal production line.

[0023] 2. In this application, the dust discharge mechanism allows dust with high moisture content to settle and accumulate along the funnel. When it accumulates to a certain amount, it can be compressed to facilitate subsequent transfer and recycling, preventing the dust from being too loose and scattering during the transfer process. At the same time, it can make full use of the current storage space and avoid the need to increase the size of the equipment or frequently transfer it. Attached Figure Description

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Example 1:

[0035] Reference Figures 1-6 One embodiment provided in this application is a dust removal device for a concrete production line, comprising an outer shell 1, a dust removal mechanism 2 disposed in the middle of the outer shell 1, a dust discharge mechanism 3 disposed in the lower part of the outer shell 1, and a fan 4 disposed in the top of the outer shell 1.

[0036] The dust removal mechanism 2 includes a rotating shaft 201, a mounting frame 202 fixedly connected to the outside of the rotating shaft 201, multiple filter plates 203 fixedly connected inside the mounting frame 202, an L-shaped plate 204 arranged below the mounting frame 202, an ultrasonic generator 205 fixedly connected to the rear end of the L-shaped plate 204, a baffle 206 slidably connected to the top of the mounting frame 202, one end of the rotating shaft 201 passing through the outer shell 1 and fixedly connected to a fan blade 207, a hollow disc 208 slidably connected to the outside of the fan blade 207, the upper rear side of the hollow disc 208 communicating with the outer shell 1 through a pipe 209, the bottom of the hollow disc 208 communicating with the outer shell 1 through a pipe 210, and the two ends of the L-shaped plate 204 being fixedly connected. The L-shaped plate 204 is fixedly connected to the front end of the inner side of the outer shell 1. The two ends of the baffle 206 are fixedly connected to the two sides of the inner side of the outer shell 1, and the rear end of the baffle 206 is fixedly connected to the rear end of the inner side of the outer shell 1. The hollow plate 208 is fixedly connected to the middle of one side of the outer shell 1 on the side near the mounting bracket 202. The pipe 209 is provided with a bracket 5 on the outside. The bracket 5 is fixedly connected to the rear of one side of the outer shell 1 on the side near the mounting bracket 202. The front cover 6 is hinged to the front side of the outer shell 1. The two ends of the rotating shaft 201 are rotatably connected to the inside of the outer shell 1. Multiple scrapers 211 are slidably connected to the outside of the mounting bracket 202. The two ends of the mounting bracket 202 are rotatably connected to the two sides of the inner side of the outer shell 1.

[0037] Specifically, with the start of the high-power fan 4, outside air and dust can enter the housing 1 through the reserved air inlets in the lower part of the housing 1 surface. Some of the dust particles with small volume and low moisture content can move upward with the air and move from the space between the housing 1 and the L-shaped plate 204 to the area where the mounting bracket 202 and filter plate 203 are located. Then, the nano-level filter plate 203 can be used to effectively separate the air and small particulate dust.

[0038] Simultaneously, the L-shaped plate 204 and the outer casing 1 cooperate to form a space for accommodating water. Therefore, by using an additional water pump, water pre-injected into this space can enter the hollow disc 208 through pipe 209. As water accumulates on the surface of the fan blade 207, it causes the fan blade 207 to rotate continuously under force. The water entering the hollow disc 208 can return to the space formed by the L-shaped plate 204 and the outer casing 1 through pipe 210 at the bottom of the hollow disc 208. At the same time, as the fan blade 207 rotates, the rotating shaft 201, which is limited by the outer casing 1, can drive the mounting frame 202 and the evenly distributed filter plates 203 to rotate forward synchronously along the baffle 206. This allows the filter plates 203, which are evenly distributed in a circle around the axis of the rotating shaft 201, and the dust filtered by them to be immersed in the water one by one. Furthermore, the ultrasonic generator 205 is activated to generate microbubbles and impact force through water wave conduction. This allows for the efficient and simple removal of a large amount of small dust particles adhering to the surface of other filter plates 203 while ensuring the filtration effect using some filter plates 203. This improves the stability and dust reduction effect of the equipment during continuous operation, reduces the difficulty of daily maintenance, and when the filter plates 203 leave the water and re-contact with the baffle 206, the water remaining on their surface can increase the water content in the air after the air passes through. This can enhance the subsequent dust settling effect after the air is discharged from the top of the outer casing 1. At the same time, during the rotation of the mounting frame 202 around the rotating shaft 201, gravity can be used to move each scraper 211 along the surface of the mounting frame 202, thereby further scraping off the adhering dust.

[0039] Furthermore, the connections between the baffle 206 and the mounting bracket 202 and the outer casing 1 prevent air from carrying dust directly to the baffle 206 without contacting the filter plate 203. Simultaneously, the outer casing 1 limits the movement of the rotating shaft 201, ensuring it doesn't shift during rotation. The connection between the hollow disc 208 and the outer casing 1 prevents water leakage after entering the hollow disc 208. The bracket 5 supports the pipe 209 and provides a mounting position for the water pump. Depending on the amount of dust at different points on the production line, for applications requiring continuous operation of the ultrasonic generator 205, the flexible pipe 209 can be extended to mount the water pump on an additional support frame. For applications with lower dust levels requiring only intermittent pump operation, the flexible pipe 209 can be extended. The water pump is installed inside the bracket 5 with rubber pads to prevent damage to the water pump caused by the use of the ultrasonic generator 205, thus improving the stability and reliability of the equipment during use. The water pump power needs to be controlled to prevent the water entering the hollow plate 208 from having a large impact force, which would cause the fan blade 207 to drive the rotating shaft 201, mounting bracket 202, etc. to rotate backward. At the same time, a hollow filter cartridge needs to be installed at the connection between the pipe 209 and the outer casing 1 to prevent large-volume debris from entering the pipe 209. After the equipment is used up and the water is drained, the front cover 6 can be opened to rinse the mounting bracket 202, filter plate 203, L-shaped plate 204, etc., to prevent residual debris. At the same time, the slope of the inner surface of the L-shaped plate 204 also helps the water to carry the debris to the front cover 6 for easy cleaning of the device and to extend the service life of the device.

[0040] Example 2:

[0041] Reference Figure 3 and Figure 7 The ash discharge mechanism 3 includes a hydraulic rod 301, the top end of which is fixedly connected to the bottom end of the L-shaped plate 204, and a pressure block 302 is fixedly connected to the output end of the hydraulic rod 301. A funnel 303 is fixedly connected to the bottom of the outer shell 1, and a bottom plate 304 is slidably connected to the bottom of the funnel 303. A frustum 305 is fixedly connected to the outer side of the output end of the hydraulic rod 301, and the bottom end of the frustum 305 is fixedly connected to the outer side of the top end of the pressure block 302. A second baffle 306 is provided above the funnel 303, and the outer side of the second baffle 306 is fixedly connected to the lower part of the inner side of the outer shell 1.

[0042] Specifically, when dust with a high moisture content enters the outer casing 1 with the air, it can settle and fall onto the surface of the funnel 303. Since the surface slope of the funnel 303 is greater than 60 degrees, the dust can slide along the surface of the funnel 303 to the square recessed area in its center. When a certain amount of dust is present in the central recessed area, the hydraulic rod 301 can be activated, so that the pressure block 302, which matches the square recessed area in the center of the funnel 303, can move downward under the action of the hydraulic rod 301. This achieves the purpose of compressing the collected dust, preventing the loose dust from being significantly scattered when the bottom plate 304 is pulled to transfer the dust for recycling. At the same time, the compression can significantly reduce the amount of dust. By reducing the space occupied by dust, more dust can be stored in a limited space, avoiding the need to increase the footprint of the device. This allows the device to be placed closer to the production line, reducing the possibility of large-scale dust diffusion during the production process. In addition, the frustum 305 increases the contact area between the hydraulic rod 301 and the pressure block 302, allowing the pressure block 302 to apply sufficient pressure. The baffle 306 can block airflow to a certain extent, preventing some settleable dust from moving upward with the air under inertia to the area where the filter plate 203 is located, thus avoiding the accelerated turbidity of the water due to the additional filtration capacity of the filter plate 203.

[0043] Working Principle: In actual use, a high-power fan 4 continuously carries dust particles into the outer casing 1. Large dust particles and dust with high moisture content settle onto the surface of the funnel 303 and then collect along the funnel 303 to the area directly below the pressure block 302. When the accumulated dust reaches a certain level, the hydraulic rod 301 is activated to compress the dust in the pressure block 302, allowing more dust to be contained within a limited space, avoiding frequent cleaning. Furthermore, the compressed dust is less likely to scatter, making subsequent transfer for recycling easier. In addition, small dust particles or dust with low moisture content in the air can come into contact with the filter plate 203 with the airflow, where they are effectively separated by the nano-scale filter plate 203. Under the action of the pump, the fan blade 207 can rotate, which in turn causes the shaft 201, the mounting bracket 202 and each filter plate 203 to rotate synchronously. At this time, the dust blocked on the surface of a certain filter plate 203 can move with the filter plate 203. Meanwhile, since the liquid level of the water stored in the space formed by the L-shaped plate 204 and the outer shell 1 is close to the height of the shaft 201, the filter plate 203 can be completely immersed in the water as it moves. At this time, the ultrasonic generator 205 can clean the filter plate 203 with the water, preventing the filter plate 203 from being affected by too much dust on its surface, thus avoiding affecting the dust reduction effect. At the same time, since there are always multiple filter plates 203 on the surface of the mounting bracket 202 in working condition, the dust reduction purpose can be continuously and effectively achieved.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
