Description

Technical Field

[0001] This utility model relates to the field of construction waste treatment and processing, and in particular to a sand-making device for construction solid waste. Background Technology

[0002] Construction waste refers to the general term for slag, waste concrete, waste bricks and stones, and other waste generated during the production activities of the construction industry, such as demolition, construction, decoration, and repair. Construction waste does not contribute to the construction itself, but it is a material generated during the construction process and needs to be screened to collect construction waste of different sizes for reuse. Existing construction waste often contains a variety of mixed materials; for example, discarded concrete waste may contain a lot of plastic packaging or curtain wall fabric. This type of waste interferes with the screening of concrete, preventing effective screening.

[0003] In the prior art, Chinese patent publication number CN218574301U discloses a construction waste screening device, which uses a hook structure to separate lightweight materials from construction waste. Common lightweight materials include plastic bags, canvas and wallpaper. During the operation of the above-mentioned lightweight materials, effective mineral sand components are easily left behind, resulting in poor separation effect and causing material throwing and dust or mineral sand particles to remain during separation. Utility Model Content

[0004] The purpose of this invention is to address the problem of incomplete separation of lightweight materials in construction waste in existing technologies, and to propose a waste removal device for sand making from construction solid waste.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sand-making and impurity removal device for construction solid waste includes a frame, a feeding device on the frame, a plurality of blocking blocks on the feeding device with gaps between the blocking blocks, a discharging device on one side of the feeding device, a hooking device between the discharging device and the feeding device, a collection trough below the feeding device located on the frame, a vibrating motor on the frame, the output end of the vibrating motor being connected to the feeding device, the vibrating motor being electrically connected to an external power source, the hooking device including a rotating shaft connected to the frame, a plurality of scraping components on the rotating shaft passing through the gaps during rotation, a rotating motor on the frame, the output end of the rotating motor being connected to the rotating shaft, the rotating motor being electrically connected to an external power source.

[0007] Preferably, the feeding device includes a first hopper connected to the frame, a plurality of first scrapers at the discharge end of the first hopper, a blocking block connected to the first scrapers, and a filter screen at the bottom of the first hopper for preliminary screening of the raw materials.

[0008] Preferably, the feeding device includes a second hopper, which is connected to the frame. The feeding end of the second hopper is provided with a plurality of second scrapers, which are spaced apart to form the gap. A scraper strip is provided in the gap and is connected to the second hopper.

[0009] Preferably, the blocking block is a trapezoidal block, and the blocking block is provided with a plurality of first protrusions.

[0010] Preferably, the scraper includes hooks, which are arranged in pairs to form the scraper. Each hook has several second protrusions and a blocking hook at one end.

[0011] Preferably, a baffle is provided above the rotating shaft. The baffle is used to block the lightweight material and dust thrown by the scraper during the screening process. The baffle is connected to the frame.

[0012] The beneficial effects proposed by this utility model are as follows:

[0013] Construction waste is dumped into the feeding device, and the vibrating motor starts, causing the feeding device to vibrate. During this process, the construction waste gradually moves forward under the influence of vibration. To ensure that the construction waste only moves towards the discharge end of the feeding device, it needs to be continuously fed. Once a certain amount of material is supplied, the feed end of the feeding device becomes an obstacle to the construction waste, preventing it from moving towards the feed end due to vibration. Meanwhile, the discharge end of the feeding device is unobstructed, allowing the construction waste to move only towards the discharge end. During vibration, the aggregate portion of the construction waste is output from the feeding device and collected in the collection trough, while lightweight materials are blocked by the blocking block at the discharge end of the feeding device, preventing them from falling into the collection trough. Simultaneously, some aggregate falls into the collection trough through the gaps. During the continuous vibrating feeding process of the feeding device, the rotating motor starts and drives the rotating shaft to rotate. At this time, the scraper continuously passes through the gap by rotating. When the lightweight material is blocked by the blocking block, the collection area is located at the gap. Therefore, when the scraper passes through the gap, it scrapes up the lightweight material and then carries it into the discharging device, from which it is discharged. This achieves the separation of lightweight material, which is useless for sand making, from construction solid waste. The blocking block is used to block the lightweight material, allowing it to hang on the blocking block. This prevents the lightweight material from being discharged into the collection trough with the aggregate. It also facilitates the separation of aggregate wrapped in lightweight material from the lightweight material, allowing the scraper to scrape it off, thus improving the separation effect between the lightweight material and the aggregate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1 to 7A sand-making and impurity removal device for construction solid waste includes a frame 1, a feeding device on the frame 1, a plurality of blocking blocks 6 on the feeding device, gaps between the blocking blocks 6, a discharging device on one side of the feeding device, a hooking device between the discharging device and the feeding device, a collecting trough 10 below the feeding device, the collecting trough 10 being located on the frame 1, a vibrating motor 2 on the frame 1, the output end of the vibrating motor 2 being connected to the feeding device, the vibrating motor 2 being electrically connected to an external power source, the hooking device including a rotating shaft 7 connected to the frame 1, a plurality of scraping parts 8 on the rotating shaft 7, the scraping parts 8 passing through the gaps during rotation, a rotating motor 3 on the frame 1, the output end of the rotating motor 3 being connected to the rotating shaft 7, the rotating motor 3 being electrically connected to an external power source. Specifically, construction solid waste is dumped into the feeding device, and the vibration motor 2 is started, driving the feeding device to vibrate. During this process, the construction solid waste gradually moves forward under the influence of vibration. To ensure that the construction solid waste only moves towards the discharge end of the feeding device, continuous feeding is required. After a certain amount of material is supplied, the inlet end of the feeding device forms an obstruction to the construction solid waste, preventing it from moving towards the inlet end due to vibration. Meanwhile, the outlet end of the feeding device is unobstructed, allowing the construction solid waste to move only towards the outlet end. During vibration, the aggregate portion of the construction solid waste is output from the feeding device and collected in the collection trough 10, while lightweight materials are blocked by the blocking block 6 at the outlet end of the feeding device, preventing them from falling into the collection trough 10. Simultaneously, some aggregate falls into the collection trough 10 through the gaps. During the continuous vibratory feeding process of the feeding device, the rotary motor 3 starts and drives the rotary shaft 7 to rotate. At this time, the scraper 8 continuously passes through the gap by rotating. When the lightweight material is blocked by the blocking block 6, the collection area is located at the gap. Therefore, when the scraper 8 passes through the gap, it will scrape up the lightweight material and then carry it into the discharge device, from which it will be discharged. This achieves the separation of lightweight material that is useless for sand making from construction solid waste. The blocking block 6 is used to block the lightweight material, allowing it to hang on the blocking block 6. This prevents the lightweight material from being discharged into the collection trough 10 along with the aggregate. It also facilitates the separation of aggregate wrapped in lightweight material from the lightweight material, allowing the scraper 8 to scrape it off, thus improving the separation effect between the lightweight material and the aggregate. It should be noted that the discharge device is a vibratory discharge device, therefore, the discharge device is connected to the feeding device, and the vibration source is provided by the vibratory motor 2.

[0024] Specifically, the feeding device includes a first hopper 5, which is connected to the frame 1. The discharge end of the first hopper 5 is equipped with several first scrapers 12, and the blocking block 6 is connected to the first scrapers 12. A filter screen 11 is provided at the bottom of the first hopper 5, which is used for preliminary screening of the raw materials. The first hopper 5 is used for conveying construction solid waste. When the vibrating motor 2 outputs a vibration source, the first hopper 5 uses vibration to output the construction solid waste. During the vibration process of the first hopper 5, some aggregate is filtered out through the filter screen 11, achieving preliminary screening of the incoming material and preventing the accumulation of aggregate caused by most of it being discharged from the discharge end of the first hopper 5, which would prevent lightweight materials from separating from the aggregate. When the lightweight material is blocked and separated by the blocking block 6, it will be stuck on the first scraper 12 during the material accumulation process. The first scraper 12 is located on both sides of the gap. When the scraper 8 passes through the gap, the scraper 8 will scrape off the lightweight material on the first scraper 12, thereby achieving the separation of aggregate and lightweight material.

[0025] Specifically, the feeding device includes a second hopper 9, which is connected to the frame 1. The feeding end of the second hopper 9 is provided with several second scrapers 14, spaced apart to form gaps. Scraper strips 15 are provided within these gaps and connected to the second hopper 9. When the scraper 8 rotates to the feeding end of the second hopper 9, the lightweight material hanging on it is scraped off by the second scrapers 14. After being scraped off, the lightweight material enters the second hopper 9, which discharges it under the vibration of the vibrating motor 2. Discharging the lightweight material through the second hopper 9, compared to the prior art method of using centrifugal force to throw out the lightweight material, facilitates the collection of the lightweight material and prevents it from being thrown out due to the rotation of the rotating shaft 7. In the above process, in order to accommodate the separation of lightweight materials of different sizes, the scraper 15 is set in the gap to increase the contact surface of the second scraper 14 with the lightweight material, thus avoiding the problem that the second scraper 14 fails to scrape the lightweight material during operation.

[0026] Specifically, the blocking block 6 is a trapezoidal block with several first protrusions 13. The trapezoidal slope of the blocking block 6 faces the feeding end of the first hopper 5. When the first hopper 5 continuously feeds, the blocking block 6 will initially screen the construction solid waste. When the incoming material arrives at the blocking block 6, the lightweight material will be stuck on the blocking block 6, while the aggregate will be discharged from the gap. Under the continuous feeding of the first hopper 5, the trapezoidal slope of the blocking block 6 serves as a feeding guide. When the material accumulates to a certain extent, the lightweight material will advance along the trapezoidal slope of the blocking block 6, and then enter the area of ​​the first scraper 12, where it will be stuck on the first scraper 12 for accumulation. During this process, the first protrusions 13 are evenly distributed on the surface of the blocking block 6. The function of the first protrusions 13 is to increase the surface roughness of the blocking block 6, and to use frictional resistance to firmly hang the lightweight material on the blocking block 6, thus preventing the lightweight material from falling off during the feeding process. The first protrusions 13 are preferably made of rubber, which can further increase the frictional resistance. Utilizing the aforementioned functions of the blocking block 6 and the first protrusions 13, it is also possible to prevent the lightweight material from falling off at the first scraper 12 due to vibration.

[0027] Specifically, the scraper 8 includes hooks 16, which are arranged in pairs to form the scraper 8. Each hook 16 has several second protrusions 17, and one end of each hook 16 has a blocking hook 18. The hooks 16 scrape lightweight material from the first scraper 12. Because of the gaps between the hooks 16, they can accommodate lightweight materials of different sizes. When the lightweight material is large, two hooks 16 scrape the same material; conversely, when the lightweight material is small, a single hook 16 can scrape it. When the rotating shaft 7 rotates, the gaps between the hooks 16 are filled by the scraper strip 15. When a single hook 16 scrapes lightweight material across the scraper strip 15, the scraper strip 15 can scrape the lightweight material off the hook 16. The second protrusions 17 are evenly distributed on the surface of the hook 16. The second protrusions 17 function the same as the first protrusions 13, increasing the surface friction of the components and allowing lightweight materials to adhere to the hook 16 without falling off. During the rotation of the hook 16, the blocking hook 18 prevents lightweight materials from slipping off the hook 16 due to centrifugal force generated by the rotation. Based on the function of the blocking hook 18, the same blocking device can be provided on both the second scraper 14 and the scraper strip 15 to prevent lightweight materials from being unable to discharge in the downward direction due to vibration.

[0028] Specifically, a baffle 4 is provided above the rotating shaft 7. The baffle 4 is used to block the lightweight material and dust thrown by the scraper 8 during the screening process. The baffle 4 is connected to the frame 1. During the rotation of the rotating shaft 7, the scraper 8 is driven to rotate. The scraper 8 scrapes the lightweight material by rotating. During this process, sand and gravel particles will be thrown away due to centrifugal force, causing dust. Small lightweight materials will also be thrown up. Therefore, the baffle 4 is set above the working area of ​​the rotating shaft 7 to prevent dust and thrown materials from falling outside the equipment.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
