Description

[0002] Water conservancy project construction shares many similarities with general civil engineering projects, such as roads, railways, bridges, and housing. For example, the primary construction tasks often involve earthwork, stonework, concrete, metal structures, and mechanical and electrical equipment installation. Some construction methods are common, some construction machinery can be used interchangeably, and some aspects of construction organization and management can be mutually beneficial.

[0003] During the construction of water conservancy projects, a large amount of construction waste is often generated. The weight and volume of this type of construction waste are irregular, some are large and some are heavy. Therefore, it needs to be crushed for transportation and processing, and finely screened to separate the recycled materials into different grades according to particle size, so that they can be reused for paving new roads or other construction projects.

[0004] The traditional method is to use high-speed rotating blades to crush construction waste into fine particles of a certain size, which consumes a lot of electricity resources, and the blades are easily damaged, resulting in a substantial increase in processing costs. In addition, screening devices such as vibrating screens are required to finely screen the crushed particles to meet the requirements of different particle sizes. Therefore, the structure is complex and the recycling cost is high, which cannot meet the requirements of modern environmental protection.

The upper and lower parts of the crushing cylinder 1 are connected, that is, material can be added from any port of the crushing cylinder 1, which improves the scope of use and flexibility. When the rotating mechanism 3 rotates the crushing cylinder 1, the construction waste is crushed by the crushing teeth 101 inside the crushing cylinder 1. A rotating mechanism 3 is connected to one side of the crushing cylinder 1. The rotating mechanism 3 is used to rotate the crushing cylinder 1. The crushing cylinder 1 is rotated by the rotating mechanism 3, so that the construction waste circulates and shakes inside the crushing cylinder 1 and is crushed by the crushing teeth 101.

A crushing mechanism 5 is rotatably provided inside the screening mechanism 4. A crushing hammer 505 is provided on the crushing mechanism 5. The crushing hammer 505 is rotatably provided inside the crushing cylinder 1 and is used to crush the construction waste. While the crushing cylinder 1 rotates, the crushing hammer 505 on the crushing mechanism 5 strikes the construction waste, and accelerates the crushing of the construction waste, thereby improving the crushing efficiency. The crushing cylinder 1 is rotated and crushed by the rotating mechanism 3, and small particles of construction waste are screened through the sieve holes 405 on the sieve plate 404. The construction waste is cyclically crushed and screened until it is completely crushed, thereby improving the convenience of use and the efficiency of crushing, and having low energy consumption, which helps to save new resource consumption and reduce carbon emissions.

When the sealed electric telescopic rod 302 is braked downward, the sealing plate 304 is pressed against the end of the crushing cylinder 1, and the construction waste is put into the crushing cylinder 1. After the inside of the pulverizing cylinder 1 is filled, the sealing plate 304 is used to seal the pulverizing cylinder 1. One side of the pulverizing cylinder 1 is fixedly connected by a rotating support column 301. The rotating support column 301 is connected to the sealing plate 304 by a rotating positioning block 306. When adding materials, the sealing rotating motor 303 at the bottom is first started to make the sealing rotating motor 303 correspond to the bottom of the pulverizing cylinder 1. Then, the sealing plate 304 at the bottom is pulled upwards by the sealing electric telescopic rod 302, and the bottom of the pulverizing cylinder 1 is sealed by the sealing ring 305 at the bottom. Then, the construction waste is put into the interior of the pulverizing cylinder 1 through the upper end of the pulverizing cylinder 1 to complete the feeding process.

[0043] Sealed crushing, after adding the construction waste into the crushing cylinder 1, start the upper sealed rotating motor 303 to rotate the sealing plate 304 to the top of the crushing cylinder 1, and then start the upper sealed electric telescopic rod 302 to push the sealing plate 304 to the upper end of the crushing cylinder 1, and seal the upper port of the crushing cylinder 1 through the upper sealing ring 305, and then rotate the crushing cylinder 1 through the rotating mechanism 3 to crush the construction waste, the end of the rotating support column 301 away from the crushing cylinder 1 is connected to the driven gear 307, and a rotating motor 6 is provided on one side of the driven gear 307, and a driving gear 601 is provided on the output end of the rotating motor 6, and the driving gear 601 is meshed with the driven gear 307.

The interior of the crushing support block 503 is provided with symmetrically distributed crushing hammer support shafts 504. The crushing hammer 505 is rotatably arranged on the crushing hammer support. On the support shaft 504, when the crushing motor 501 rotates, it drives the crushing shaft 502 to rotate, and the crushing hammer 505 on the crushing hammer support shaft 504 beats and crushes the construction waste. One end of the crushing shaft 502 extends to the interior of the crushing cylinder 1 and is connected to the crushing support block 503. Two crushing hammer support shafts 504 are provided inside the crushing support block 503. A crushing hammer 505 is rotatably provided on each crushing hammer support shaft 504. Therefore, when the crushing support block 503 rotates, the crushing hammer 505 can be driven to rotate inside the crushing cylinder 1, thereby achieving the purpose of crushing the construction waste inside the crushing cylinder 1. The crushing teeth 101 and the crushing hammer 505 crush the construction waste at the same time, greatly improving the crushing efficiency.

[0046] After the above operations are completed, the pulverizing drum 1 is rotated by the rotating mechanism 3 to pulverize the construction waste, and the small particles of construction waste are screened through the sieve holes 405 on the sieve plate 404. Of course, the construction waste can be pulverized and screened cyclically until it is completely pulverized, which improves the convenience of use and the efficiency of pulverization, has low energy consumption, helps to save new resource consumption, and reduces carbon emissions.

[0047] Further, such as Figure 1 and Figure 2 As shown, a support plate 703 is provided at the bottom of the crushing cylinder 1, and a support frame 7 is fixedly provided on one side of the support plate 703.

[0050] The interior of the dust collector 2 is fixedly provided with cathode wires 209 and anode modules 210 that overlap with each other, and a spray device 206 is fixedly provided above the cathode wires 209. A cathode beam 207 and a cathode beam 208 are provided between the spray device 206 and the cathode wires 209. The cathode wires 209 and the anode modules 210 can efficiently absorb dust and remove particulate matter in the air.

[0052] like Figures 1-9 As shown, the working principle of the construction waste recycling and crushing equipment provided in this embodiment is as follows:

[0053] For feeding, one side of the crushing cylinder 1 is fixedly connected via a rotating support column 301, and the rotating support column 301 is connected to a sealing plate 304 via a rotating positioning block 306. When feeding, first start the sealing rotating motor 303 at the bottom so that the sealing rotating motor 303 corresponds to the bottom of the crushing cylinder 1, then pull up the sealing plate 304 at the bottom via the sealing electric telescopic rod 302, and seal the bottom of the crushing cylinder 1 via the sealing ring 305 at the bottom, then put the construction waste into the crushing cylinder 1 through the upper end of the crushing cylinder 1, completing the feeding process;

[0054] After the construction waste is added into the crushing barrel 1, the upper sealing rotary motor 303 is started to rotate the sealing plate 304 to the top of the crushing barrel 1, and then the upper sealing electric telescopic rod 302 is started to push the sealing plate 304 to the upper end of the crushing barrel 1, and the upper port of the crushing barrel 1 is sealed by the upper sealing ring 305.

After the crushing rod through-hole 407 rotates, the crushing barrel 1 is driven to rotate as a whole, and the construction waste inside the crushing barrel 1 is crushed by the crushing teeth 101. When the crushing support block 503 rotates, the crushing hammer 505 can be driven to rotate inside the crushing barrel 1, thereby achieving the purpose of crushing the construction waste inside the crushing barrel 1. The construction waste is crushed by the crushing teeth 101 and the crushing hammer 505 at the same time, which greatly improves the crushing efficiency.

[0055] For screening, first, the upper sealing ring 305 is moved away from the port of the crushing cylinder 1 by the sealing electric telescopic rod 302, and then the sealing plate 304 is rotated to one side by the sealing rotary motor 303, and the screening rotary motor 403 on the screening mechanism 4 is started to rotate the sieve plate 404 to the upper port of the crushing cylinder 1, and then the screening electric telescopic rod 402 is started to make the sieve plate 404 seal the port of the crushing cylinder 1;

[0056] After the above operations are completed, the pulverizing drum 1 is rotated by the rotating mechanism 3 to pulverize the construction waste, and the small particles of the construction waste are sieved through the sieve holes 405 on the sieve plate 404 .
