Description

Technical Field

[0001] This application relates to the field of crushing equipment technology, and in particular to a waste concrete crushing equipment. Background Technology

[0002] Concrete, as an important building material, requires a large amount of natural resources, such as sand, gravel, and cement, to be produced. By recycling waste concrete and sorting it, the sorted waste concrete is crushed into smaller pieces. These pieces are then graded according to different particle sizes using screening equipment. This process can obtain aggregates of different particle sizes to meet different reuse needs and be used to produce new concrete or other building materials. This not only saves on the extraction of natural resources but also reduces the accumulation of construction waste, thus realizing the recycling of resources.

[0003] The crushing of waste concrete generates a large amount of dust, which not only threatens the health of operators but also may pollute the environment. If the dust accumulated inside the crusher is not cleaned for a long time, it can cause the crusher to become unusable or jam. Traditional waste concrete crushing equipment either wet-crushes the concrete before crushing or adds water during the crushing process to reduce dust generation. However, both methods waste a lot of water and make the waste concrete too wet, requiring methods such as drying or baking to reduce its moisture content, wasting resources and affecting overall production efficiency. Utility Model Content

[0004] To overcome the above-mentioned technical problems, this application provides a waste concrete crushing device.

[0005] This application provides a waste concrete crushing device, which adopts the following technical solution:

[0006] A waste concrete crushing device includes a housing, within which a crushing mechanism and a dust removal mechanism are disposed. The crushing mechanism includes a crushing roller fixedly disposed inside the housing and a crushing motor connected to the crushing roller. The dust removal mechanism includes a frame with openings at both ends forming dust removal ports, each connected to a dust removal housing. The dust removal housing is a rectangular shell with an air intake and an adsorption port inside. A grid plate is fixedly disposed at the adsorption port. An installation plate is disposed inside the dust removal housing near the grid plate and fixedly disposed at the top of the dust removal housing. A groove is formed at the top of the installation plate to form a support groove, within which a water pipe is fixedly disposed. A groove is formed at the bottom of the installation plate to form a snap-fit ​​groove, within which a stainless steel coarse filter screen is fixedly disposed.

[0007] By adopting the above technical solution, the crushing mechanism, including a crushing roller and a crushing motor, can crush waste concrete. The dust removal mechanism can achieve efficient dust control in the enclosed and highly concentrated concrete crushing environment within the equipment casing. The openings at both ends of the frame form dust removal ports and are connected to the dust removal housing, ensuring the structural stability and ease of operation of the entire equipment. The dust removal housing has an air intake and an adsorption port, with a grid plate fixedly installed at the adsorption port to effectively guide airflow and initially filter larger objects, improving subsequent processing efficiency. A stainless steel coarse filter screen is fixedly installed in the recessed slot at the bottom of the mounting plate, further intercepting larger particles and preventing them from entering the core components, extending the equipment's service life. Water pipes in the support groove are connected to nozzles through multiple fixed holes. The nozzles are evenly distributed, ensuring a wide water mist coverage area, effectively cleaning the stainless steel coarse filter screen and improving dust removal efficiency. Therefore, this application has high adaptability and dust removal efficiency, and can adapt to environments with high dust concentrations.

[0008] Preferably, the top of the equipment housing is provided with a feed inlet located above the crushing roller, and the bottom of the equipment housing is also provided with a receiving frame.

[0009] By adopting the above technical solution, the feed inlet is used to add waste concrete into the equipment housing. Setting the feed inlet above the crushing roller helps the crushing roller to crush the waste concrete more evenly.

[0011] By adopting the above technical solutions, the water receiving tank effectively collects water flowing down from the stainless steel coarse filter, preventing water from dripping onto the ground and causing secondary pollution. The U-shaped cross-section design increases the water receiving area, improves water collection efficiency, and ensures the continuity and stability of the dust removal process. The water pump can promptly discharge wastewater from the receiving tank, preventing water accumulation from affecting the normal operation of the equipment. The connection design between the wastewater pipe and the receiving tank ensures that wastewater can be smoothly transferred from the receiving tank to the external discharge point, reducing the workload of manual cleaning and maintenance costs. The coordinated operation of the entire system improves dust removal efficiency and reduces dust pollution.

[0012] Preferably, multiple through holes are spaced apart on both sides of the support groove to form fixing holes, and multiple nozzles are fixedly installed in the fixing holes, and the multiple nozzles are all connected to the water pipe.

[0013] By adopting the above technical solution, the nozzle design allows water to be sprayed evenly inside the dust collector housing, effectively cleaning the stainless steel coarse filter screen and improving dust removal efficiency. The mounting holes ensure stable nozzle installation, guaranteeing the reliability and durability of the spraying process. This design not only enhances dust removal performance but also simplifies maintenance and reduces costs.

[0014] Preferably, the frame is further provided with an adsorption mechanism, which includes an exhaust fan fixedly installed in the frame.

[0015] By adopting the above technical solution, the indoor construction dust removal fan incorporates an adsorption mechanism within its frame, including an exhaust fan fixedly installed inside the frame. This design significantly improves the dust collection efficiency of the dust removal system, enabling it to quickly capture and remove large amounts of dust, effectively improving the air quality of the construction environment. Simultaneously, the use of the exhaust fan reduces the overall operating cost of the equipment, making it more economical and practical, and suitable for long-term continuous operation.

[0016] Preferably, the adsorption mechanism further includes multiple fine filter plates, and the top of the frame is provided with multiple rectangular openings to form drawer openings. A drawer box is slidably disposed in the drawer openings, and the fine filter plates are fixedly disposed in the drawer box.

[0017] By adopting the above technical solutions, this indoor construction dust collector can effectively absorb and treat dust, improving air quality. The fine filter plate further filters the intake dust-laden air, ensuring cleaner exhaust gas and reducing the risk of secondary pollution. The drawer opening design makes the fine filter plate easy to replace and clean, reducing maintenance costs and operational difficulty, and improving the equipment's practicality. The sliding drawer box allows users to quickly open and close it, simplifying daily maintenance and improving work efficiency.

[0018] Preferably, a booster water pump is also fixedly installed inside the frame, and the booster water pump is connected to a main water pipe, which is connected to the water pipe.

[0019] By adopting the above technical solution, the setting of the pressurized water pump can ensure the stable pressure of the water flow, thereby ensuring that the water mist sprayed from the nozzle is uniform and has a wide coverage, further improving the dust removal efficiency.

[0020] Preferably, it also includes a conveyor belt mechanism, the feed end of which is connected to the feed inlet.

[0021] By adopting the above technical solution, the conveyor belt mechanism can achieve the technical effect of automatic feeding.

[0033] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0034] This application discloses a waste concrete crushing device, referring to... Figure 1 , Figure 2 and Figure 3The system includes a housing 10, within which a crushing mechanism and a dust removal mechanism are installed. The crushing mechanism includes a crushing roller 4 fixedly installed inside the housing 10, and a crushing motor 41 connected to the crushing roller 4. The crushing motor 41 drives the crushing roller 4 to crush the waste concrete. A feed inlet 6 is located at the top of the housing 10, above the crushing roller 4. A conveyor belt mechanism 5 is connected to the feed inlet 6, and the conveyor belt mechanism 5 is a conventional conveying device. The conveyor belt mechanism 5 enables automated transportation, transporting the waste concrete through the feed inlet 6 into the housing 10. A receiving frame 7 is also provided at the bottom of the housing 10. The crushed concrete falls into the receiving frame 7, and the operator only needs to periodically open the housing 10 to remove the receiving frame 7 to complete the recycling of the waste concrete. This design helps ensure the airtightness of the housing 10.

[0035] Reference Figure 4 , Figure 5 and Figure 6 To improve the dust removal performance of the equipment, the dust removal mechanism includes a frame 1, which is a rectangular shell made of metal to provide high support capacity. Dust removal ports 11 are formed at both ends of the frame 1. Each dust removal port 11 is rectangular and connected to a dust removal housing 111. The dust removal housing 111 is also a rectangular shell, and contains an air intake 112 and an adsorption port 113. The air intake 112 extends along the length of the dust removal housing 111, and the adsorption port 113 is located on one surface of the dust removal housing 111. The air intake 112 is connected to the dust removal ports 11, and the connection is sealed. The adsorption ports 113 on both sides of the dust removal housing 111 are located on the same side, facing away from the frame 1. A grid plate 114 is fixedly installed at the adsorption port 113. The grid plate 114 has grid-shaped through holes on its surface, which can prevent large objects from being sucked into the dust collector housing 111, such as thin materials like paper and plastic bags. At the same time, the grid plate 114 is made of stainless steel, which has strong durability and corrosion resistance.

[0036] Reference Figure 7 and Figure 8Inside the dust collector housing 111, near the grid plate 114, is a mounting plate 115, which is fixedly mounted on the top of the dust collector housing 111. A groove is formed at the bottom of the mounting plate 115, creating a snap-fit ​​groove 116. A stainless steel coarse filter 117 is fixedly installed within the snap-fit ​​groove 116. The stainless steel coarse filter 117 effectively intercepts large dust particles, preventing clogging of subsequent filtration devices. In actual use, the length of the dust collector housing 111 can be customized according to the size of the work site. The longer the dust collector housing 111, the longer the corresponding stainless steel coarse filter 117, resulting in higher purification efficiency. A groove is formed at the top of the mounting plate 115, creating a support groove 118. A water pipe 119 is fixedly installed within the support groove 118, extending along the length of the dust collector housing 111. A pressurized water pump 12 is also fixedly installed inside the frame 1. The pressurized water pump 12 is connected to a main water pipe 121, which is connected to the water pipe 119. Multiple through holes are spaced apart on both sides of the support groove 118 to form fixing holes 22. Multiple nozzles 21 are fixedly installed in the fixing holes 22, and the nozzle heads of the nozzles 21 are all facing the stainless steel coarse filter screen 117. The multiple nozzles 21 are all connected to water pipes 119. A pressurized water pump 12 is also fixedly installed in the frame 1. The pressurized water pump 12 is connected to a water main pipe 121, which is connected to the water pipe 119. These nozzles 21 can spray water mist onto the stainless steel coarse filter screen 117 under the action of water flow in the water pipe 119. Due to the setting of the pressurized water pump 12, the water pressure in the water pipe 119 is relatively high, which makes the water mist sprayed by the nozzles 21 high-pressure water mist. This high-pressure water mist sprayed on the stainless steel coarse filter screen 117 can wash away the larger dust shells captured on the stainless steel coarse filter screen 117. This setting enables the equipment to adapt to environments with high dust concentration, remove large amounts of dust, and make the dust combine with water and settle down, thereby achieving a faster and better dust removal effect. A water receiving trough 23 is fixedly installed at the bottom of the stainless steel coarse filter screen 117. The cross-section of the water receiving trough 23 is U-shaped. The water receiving trough 23 is used to store sewage. A sewage pump 14 is also installed in the frame 1. The sewage pump 14 is connected to a sewage pipe 13. The end of the sewage pipe 13 away from the sewage pump 14 is connected to the water receiving trough 23. The sewage pump 14 is used to pump the sewage out of the water receiving trough 23 for timely cleaning to maintain the continuous operation of the equipment.

[0037] An adsorption mechanism is also provided inside the frame 1, which includes a fan 33 fixedly installed inside the frame 1. The adsorption mechanism also includes multiple fine filter plates 32. Multiple rectangular openings forming drawer openings 35 are provided at the top of the frame 1, and these drawer openings 35 are exposed outside the equipment housing 10. A drawer box 34 is slidably installed inside the drawer openings 35, and the fine filter plates 32 are fixedly installed inside the drawer box 34. The fine filter plates 32 use HEPA filters, which can effectively capture fine particulate matter and ensure air quality. The design of the drawer box 34 facilitates daily cleaning and maintenance for users, eliminating the need for frequent disassembly and reassembly of the entire equipment.

[0038] The implementation principle of this embodiment is as follows: The conveyor belt mechanism 5 transports waste concrete through the feed inlet 6 into the equipment housing. The crushing roller 4 first crushes the concrete, and the crushed concrete falls into the receiving frame 7. During this process, a large amount of dust is generated. When the dust removal mechanism is performing dust removal, the exhaust fan 33 continuously draws air from the construction site. The dust-laden air enters through the adsorption port 113 and is filtered through the stainless steel coarse filter screen 117. Larger dust particles are adhered to the stainless steel coarse filter screen 117. Since both the nozzle 21 and the stainless steel coarse filter screen 117 are located inside the dust removal housing 111, the water sprayed from the nozzle 21 will not disperse in the crushing environment as water mist, avoiding the impact of moisture on the concrete material. It also prevents the water mist from freezing inside the crushing device when the temperature is low in winter. Wastewater is stored in the water receiving tank 23 and pumped out by the wastewater pump 14.

[0039] Air passing through the stainless steel coarse filter 117 will be drawn by the exhaust fan 33 to the fine filter plate 32 for further filtration, further filtering out dust in the air and minimizing the harm to the human body from the exhaust air.

[0040] 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.
