Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology and discloses a large-scale construction waste crushing device. Background Technology

[0002] Construction waste refers to the excavated soil, materials, and other waste generated during the construction, renovation, expansion, and demolition of various buildings, structures, and pipelines. To better manage and dispose of construction waste, many cities and regions have formulated relevant laws, regulations, and technical standards to guide this process.

[0003] Patent CN216324142U discloses a shredder compressor specifically for construction waste, including a housing vertically fixed to the top of the ground, with a fixed rod vertically rotatably connected inside the housing. This patent utilizes an electromagnet to automatically pick out metal fragments from the construction waste after shredding, thus eliminating the need for manual sorting. However, in actual use, because construction waste is relatively dry, a large amount of dust is easily generated during shredding. If this dust is released into the air without treatment, it will pollute the environment.

[0004] Therefore, a large-scale construction waste shredding device with dust reduction function is needed. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents in actual use, which are prone to generating a large amount of dust during the crushing process due to the dryness of construction waste, and which will cause environmental pollution if the dust is released into the air without treatment, this utility model provides a large-scale construction waste crushing device.

[0006] The technical solution of this utility model is as follows: a large-scale construction waste crushing device, comprising a base plate, a feeding shell, a crushing shell, a drive motor, a rotating shaft I, a crushing roller, a conveying assembly, a support frame, a rotating shaft II, and a conveyor belt. The feeding shell is fixedly connected to the base plate, and the crushing shell is fixedly connected to the lower end of the feeding shell. The drive motor is installed on the front side of the base plate. The rotating shaft I is rotatably arranged inside the crushing shell, and the crushing roller is fixedly connected to the outer side of the rotating shaft I. The output shaft of the drive motor and the rotating shaft I are jointly provided with a conveying assembly. Two support frames are fixedly connected to the base plate, and the two support frames are rotatably arranged with the rotating shaft II. The rotating shaft II and the output shaft of the drive motor are jointly provided with a conveyor belt. It also includes a water tank, a water pump, and an atomizing nozzle. The water tank is installed on the base plate, and the water pump is installed on the front side of the water tank. The atomizing nozzle is connected and communicated with the water pump, and the atomizing nozzle extends into the interior of the feeding shell.

[0007] In one embodiment, the device further includes a flap, a rotating shaft III, and a torsion spring. Two rotating shafts III are fixedly connected to the top of the feed housing. Both rotating shafts III are rotatably equipped with flaps. Torsion springs are sleeved at both ends of the rotating shafts III. The two ends of the torsion springs are respectively connected to the feed housing and the rotating shaft III.

[0008] In one embodiment, the system further includes a connecting plate, a servo motor, a transmission roller, a conveyor belt, a de-energized electromagnet, and a scraper. Two connecting plates are fixedly connected to two support frames. A servo motor is mounted on the front support frame. Two transmission rollers are rotatably mounted on the two connecting plates. The two transmission rollers are fitted with the conveyor belt. The output shaft of the servo motor is connected to the front transmission roller. Multiple de-energized electromagnets are embedded in the conveyor belt. A scraper is fixedly connected to the rear side of the two support frames.

[0009] In one embodiment, a power generation block is also included, with the power generation block being fixedly connected to two support frames.

[0010] In one embodiment, a limiting shell is also included, which is fixedly connected inside the crushing shell.

[0011] In one embodiment, an observation panel is also included, which is embedded in the left side of the water tank.

[0012] The beneficial effects are: 1. The water pump draws water from the water tank into the atomizing nozzle, which then sprays the water evenly onto the large construction waste, keeping it moist and thus reducing dust and preventing the generation of a large amount of dust during the crushing process from polluting the environment.

[0013] 2. The flap is no longer squeezed, and the torsion spring returns to its original shape, causing the flap to rotate upward and close the feed shell, thereby preventing construction waste from splashing out during the crushing process.

[0014] 3. The output shaft of the servo motor rotates, which drives the transmission roller to rotate, and then the conveyor belt to rotate. At this time, the de-energized electromagnet adsorbs the metal substances in the crushed construction waste, thereby achieving effective screening and improving resource utilization.

Detailed Implementation

[0021] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: A large-scale construction waste shredding device, please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 5 The system includes a base plate 1, a feed shell 2, a crushing shell 3, a drive motor 7, a rotating shaft I 8, a crushing roller 9, a conveying assembly 10, support frames 11, a rotating shaft II 12, and a conveyor belt 13. The feed shell 2 is fixedly connected to the base plate 1, and the crushing shell 3 is fixedly connected to the lower end of the feed shell 2. The drive motor 7 is bolted to the front of the base plate 1. The rotating shaft I 8 is rotatably mounted inside the crushing shell 3, and the crushing roller 9 is fixedly connected to the outer side of the rotating shaft I 8. The output shaft of the drive motor 7 and the rotating shaft I 8 together form the conveying assembly 10. Two support frames 11 are fixedly connected to the base plate 1. The rotating shaft II 12 is provided, and the output shaft of the rotating shaft II 12 and the drive motor 7 are connected together to the conveyor belt 13. The water tank 4 is provided on the base plate 1 by bolt connection. The top of the water tank 4 is provided with a screw cap. Rotating the screw cap opens the water tank 4, and water can be added into the water tank 4. The chemical spray pipe 6 extends into the inside of the feed shell 2. The crushing shell 3 is fixedly connected to the limiting shell 24, which limits the crushed construction waste to prevent the crushed construction waste from accumulating too high. An observation plate 25 is embedded on the left side of the water tank 4, which makes it easy to directly check the water level inside the water tank 4.

[0023] When large construction waste needs to be processed, it is poured into the feed hopper 2, and the water pump 5 is turned on at the same time. The water pump 5 draws water from the water tank 4 into the atomizing nozzle 6. The atomizing nozzle 6 sprays water evenly onto the large construction waste to keep it moist, thereby reducing dust and preventing the generation of a large amount of dust during the crushing process from polluting the environment. While ensuring that the construction waste is moist, the drive motor 7 is turned on. The output shaft of the drive motor 7 rotates, driving the conveyor assembly 10 and a rotating shaft II 12 to rotate. The rotation of the conveyor assembly 10 drives the rotating shaft I 8 to rotate, thereby starting the crushing roller 9 to crush the large construction waste. The crushed construction waste will fall onto the conveyor belt 13 below. The rotation of the rotating shaft II 12 drives the conveyor belt 13 to rotate, and the conveyor belt 13 transports the crushed construction waste to the right for subsequent processing or collection.

[0024] Example 2: Based on the example, please refer to... Figure 3 Two rotating shafts Ⅲ15 are fixedly connected to the top of the feed shell 2. Both rotating shafts Ⅲ15 are rotatably equipped with flaps 14. Torque springs 16 are sleeved at both ends of the rotating shafts Ⅲ15. The two ends of the torsion springs 16 are connected to the feed shell 2 and the rotating shafts Ⅲ15 respectively.

[0025] When construction waste is poured into the feed hopper 2, the construction waste squeezing flap 14 rotates downward to open the feed hopper 2. At the same time, the torsion spring 16 deforms accordingly. After all the construction waste has entered the feed hopper 2, the flap 14 is no longer squeezed. At this time, the torsion spring 16 returns to its original shape, causing the flap 14 to rotate upward to close the feed hopper 2, thereby preventing construction waste from splashing out during the crushing process.

[0026] Please see Figure 4 and Figure 5 Two support frames 11 are fixedly connected to two connecting plates 17. A servo motor 18 is bolted to the front support frame 11. Two transmission rollers 19 are rotatably mounted on the two connecting plates 17. The two transmission rollers 19 are fitted with a conveyor belt 20. The output shaft of the servo motor 18 is connected to the front transmission roller 19. Several de-energized electromagnets 21 are embedded in the conveyor belt 20. A scraper 22 is fixedly connected to the rear of the two support frames 11. A generator block 23 is fixedly connected to the two support frames 11. When the generator block 23 is turned on, the de-energized electromagnets 21 lose their magnetism when they approach the generator block 23, thus facilitating the scraper 22 to scrape off the metal material on the conveyor belt 20.

[0027] After the construction waste is crushed, the servo motor 18 is turned on. The output shaft of the servo motor 18 rotates, which drives the transmission roller 19 to rotate, and then the conveyor belt 20 rotates. At this time, the de-energized electromagnet 21 adsorbs the metal material in the crushed construction waste, thereby achieving effective screening and improving resource utilization. The conveyor belt 20 continues to run, conveying the metal material backward, so that the scraper 22 comes into contact with the metal material, scraping the metal material off the conveyor belt 20 and collecting it.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
