[0028] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0030] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the utility model described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0031] In the existing technology, in order to avoid dust from escaping during concrete crushing, dust suppression is currently carried out by dust collection or wet crushing. Although wet crushing by adding water can reduce dust generation better, it wastes water resources seriously. Dust collection by fans usually involves the installation of a filtration mechanism. The sieve plate or bag filter of the filtration mechanism has poor dust removal effect, the filtration mechanism is prone to clogging and needs to be cleaned frequently, and it is easy to suck in gravel, which will affect the fan.

[0032] This utility model provides a concrete crushing device with a dust removal mechanism 7, such as... Figure 1 and Figure 2 As shown, in this embodiment, the concrete crushing equipment includes a crusher body and a feed box 2 connected to the upper end of the crusher body. The feed box 2 serves as the concrete feeding part of the crusher body. A feed inlet is provided on the feed box 2 to allow concrete to enter the feed box 2. The crusher body includes a support platform 1, a crushing box 3, a crushing roller 4, a drive motor 5, and a reduction gearbox 6. The crushing box 3, the drive motor 5, and the reduction gearbox 6 are installed on the support platform 1. The feed box 2 is fixed on the crushing box 3 and communicates with the crushing box 3. The crushing roller 4 is installed inside the crushing box 3. The drive motor 5 is connected to the reduction gearbox 6 to drive the crushing roller 4 to rotate for crushing. A discharge port is provided at the bottom of the crushing box 3. An opening is provided on the support at the discharge port to allow the crushed material to be discharged. A screw conveyor can be connected to the discharge port to discharge the material and prevent dust from escaping during discharge. During crushing, concrete is fed from the feed inlet. After entering the feed box 2, the concrete flows downward into the crushing box 3 for crushing. The crushed concrete material is discharged from the discharge port.

[0033] In order to achieve stable dust suppression and avoid damage to the fan during dust collection or from gravel; such as Figure 3 As shown, a dust removal mechanism 7 is provided on one side of the feed inlet at the top of the feed box 2. The top of the feed box 2 has a connection port that communicates with the dust removal mechanism 7 and can be connected to an external fan. The dust removal mechanism 7 has a dust removal channel 73 and an atomizer 72 that sprays water mist into the dust removal channel 73. The atomizer 72 is connected to an external water tank and sprays water mist into the dust removal channel 73 for dust suppression.

[0034] This invention features a dust removal mechanism 7 installed at the top of the feed box 2. By placing the dust removal mechanism 7 before the input end of the blower, dust or gravel is prevented from affecting the operation of the blower, thus extending its service life. The dust is atomized and then deposited into the dust collection box 71. The combination of dust collection and atomization achieves a good dust removal effect, ensuring a good working environment. Compared with existing atomized dust suppression methods, the atomized water is less likely to enter the crushed concrete, thus preventing the concrete material from becoming wet and improving the quality of concrete crushing.

[0035] To improve the dust removal efficiency of the dust removal mechanism 7 and prevent dust from entering the fan; such as Figure 4 and Figure 5 As shown, the dust removal mechanism 7 is configured as a dust removal box 71 and multiple dust removal plates 74 disposed within the dust removal box 71. In this embodiment, four dust removal plates 74 are provided. The dust removal box 71 is detachably installed on the inner top wall of the feed box 2 by screws, facilitating the overall installation and disassembly of the dust removal box 71. The four dust removal plates 74 are staggered and spaced apart within the dust removal box 71, and are arranged parallel to each other. The dust removal plates 74 are also detachably installed within the dust removal box 71 for easy installation and disassembly. Due to the staggered arrangement of the dust removal plates 74, a bent dust removal channel 73 is formed between the four dust removal plates 74. The atomizer 72 is installed on one side inside the dust removal box 71 and sprays water mist into the dust removal channel 73 to reduce dust. The water mist combines with the dust in the gas and is adsorbed onto the dust removal plates 74. The atomizer 72 is designed to be detachable for easy maintenance. To ensure a stable water supply, a water pump can be installed between the atomizer 72 and the water tank for stable delivery.

[0036] To facilitate the cleaning of dust and atomized water accumulated on the dust collector plate 74, a maintenance opening is provided on the side of the dust collector box 71. A closable maintenance door 75 is connected to the dust collector box 71. The maintenance door 75 is located on the side of the dust collector box 71 away from the atomizer 72. The maintenance door 75 can close the maintenance opening. The maintenance door 75 is hinged to the dust collector box 71. A sealing gasket is provided between the maintenance door 75 and the dust collector box 71 to ensure airtightness. At the same time, an opening and closing door is provided on the outside of the feed box 2, so that the maintenance door 75 can be opened directly from the outside for cleaning without removing the dust collector box 71. During cleaning, the dust collector plate 74 can be removed for cleaning.

[0037] To ensure the stability of the dust collector 71 installation and the ease of connection with the fan, an air inlet and an air outlet are respectively provided at the top and bottom of the dust collector 71. A plug pipe 76 is fixedly connected to the air outlet. One end of the plug pipe 76 is inserted into the connection port, and the outer wall of the plug pipe 76 fits against the inner wall of the connection port. The inner wall of the plug pipe 76 is provided with internal threads. A threaded connector is provided on the fan's connection pipe and is inserted into the plug pipe 76 in the connection port for threaded connection. The plug pipe 76 is provided to provide positioning during the installation of the dust collector 71, improving the convenience and accuracy of the installation. The threaded connector facilitates a stable connection with the fan and is easy to disassemble, allowing for quick switching to a backup fan in case of fan failure.

[0038] To improve the comprehensiveness of dust collection, an air inlet hood 77 is connected to the air inlet. The opening of the air inlet hood 77 is set to face the feed inlet to ensure that dust can enter the dust collection box 71 during feeding. The air inlet hood 77 has a windward surface, and an annular groove is provided on the inner side of the windward surface. During dust collection, the dust comes into contact with the windward surface of the air inlet hood 77, which can leave large dust particles on the air inlet hood 77.

[0039] In another embodiment, a protective net is provided on the air inlet shroud 77 to prevent gravel from entering and to prevent gravel from damaging the air inlet shroud 77.

[0040] In another embodiment, a scraping mechanism is provided inside the air inlet hood 77, which can periodically scrape the inner wall of the air inlet hood 77 to remove dust adsorbed on the inner wall of the air inlet hood 77.

[0041] To improve dust suppression, two atomizers 72 are set up. The atomizer 72 closer to the air inlet has a higher output power than the atomizer 72 farther away from the air inlet. When dust first enters, the atomizer 72 with higher power sprays out a large amount of water mist to suppress the dust. When the remaining dust flows with the gas to the upper end of the dust removal channel 73, the atomizer 72 with lower power sprays out a small amount of water mist to suppress the dust, thus avoiding waste of water resources.

[0042] To prevent dust from overflowing during crushing, a cover plate 21 that can open and close the feed inlet is hinged to the feed box 2. When crushing concrete, the feed inlet of the feed box 2 is closed by the cover plate 21, which can prevent dust from overflowing during crushing.

[0043] To improve the dust removal effect, the surface of the dust removal plate 74 is made into a wave shape, and a layer of the surface of the dust removal plate 74 is made into a honeycomb shape, which increases the contact area between the dust removal plate 74 and the surface and the gas, and improves the blocking and adsorption of dust in the passing gas while atomizing and reducing dust.

[0044] To prevent water from accumulating in the feed box 2 during water mist dust suppression, a water storage chamber is provided inside the dust removal plate 74. A filter section connected to the water storage chamber is provided at the upper end of the dust removal plate 74. The filter section is made of a porous material on the upper surface of the dust removal plate 74, allowing water to permeate into the water storage chamber.

[0045] The working principle of this utility model is as follows: Since a large amount of dust is generated during the feeding and crushing of concrete, the blower is connected to the dust collection box 71 before crushing and is opened before the concrete is fed. After the blower is connected and started, the atomizer 72 is turned on, and then the cover plate 21 is opened to feed the concrete from the feed port. The fed concrete enters the crushing box 3 for crushing. After crushing, the concrete is discharged from the discharge port. During the feeding and crushing process, the start of the blower creates a negative pressure at the air inlet hood. The dust generated during the feeding and crushing process enters the air inlet hood 77 and then enters the dust collection channel 73. In the dust collection channel 73, the two atomizers 72 spray water mist into the dust collection channel 73. Through the coverage of the water mist, the dust in the gas combines with the water mist and falls onto the dust collection plate 74. The dust-collected gas is then transported to the blower for discharge.
