Description

Technical Field

[0001] The present application relates to the technical field of construction waste, and in particular to a device for treating construction waste in civil engineering. Background Art

[0002] Construction waste refers to the general term for slag, waste concrete, waste bricks and stones and other wastes generated during people's production activities in the construction industry such as demolition, construction, decoration, and repair. Construction waste can be divided into engineering slag, decoration waste, demolition waste and engineering mud, etc. Construction waste is generally processed in the form of crushing.

[0003] The existing Chinese patent with announcement number CN216224608U discloses a civil engineering construction waste treatment device, including a treatment box, a support frame is fixedly installed at the lower part of the treatment box, a feed trough is arranged at the upper end of the treatment box, a discharge trough is arranged at the lower end of the treatment box, a driving crushing mechanism is inserted and connected to the left side of the rear end of the treatment box, and two transmission crushing mechanisms are inserted and connected to the right side of the rear end of the treatment box, and the two transmission crushing mechanisms are distributed up and down, and the two transmission crushing mechanisms are both connected to the driving crushing mechanism in a transmission manner, and the upper and lower parts of the left and right inner walls of the treatment box are fixedly installed with extrusion arc cylinders, and the middle and lower parts of the left and right inner walls of the treatment box are opened with movable grooves, and a filtering mechanism is slidably installed between the two movable grooves located on the same horizontal plane. The civil engineering construction waste treatment device described in the utility model can achieve two crushings through one motor, has stable transmission, compact structure, low energy consumption, sufficient and efficient crushing, good filtering effect, and the filter screen is not easy to be blocked, and the processing efficiency is high.

[0004] However, the above-mentioned waste processing device has the following disadvantages: the device vibrates the filter plate by setting a retractable rod and a spring to shake off the blocked waste. However, after the crushing mechanism of the device crushes the waste, some waste that is larger than the filter holes of the filter will remain on the filter, and the waste remaining on the filter cannot be further crushed. Too much waste accumulation will affect the filtering effect of the filter and reduce the filtering efficiency. Although the vibration can shake off some residual waste, it cannot completely solve the problem of blocked waste. These wastes are stuck in the filter holes of the filter, which greatly reduces the service life of the filter.

[0005] Therefore, we propose a civil engineering construction waste treatment device to solve this problem.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0027] The implementation principle of a civil engineering construction waste treatment device in the embodiment of the present application is as follows: when in use, the collecting device is placed at the outlet of the treatment box 1, and then the second motor 3 is started, the second motor 3 drives the second rotating shaft 17 to rotate, and the second rotating shaft 17 drives the baffle 4 to rotate up, blocking the collecting device on the base, and then the construction waste is input into the treatment box 1, and the waste is crushed by the crushing mechanism above. The crushed waste falls onto the first sieve plate 6 for screening, and then falls into the crushing mechanism below for further crushing. After crushing, it is screened by the second sieve plate 9, and the screened waste is output to the treatment box 1. At this time, waste larger than the sieve holes of the sieve plates will remain on the first sieve plate 6 and the second sieve plate 9, and the waste remaining on the filter screen cannot be crushed by the crushing mechanism.

During the crushing process, waste may be blocked in the sieve holes of the first screen plate 6 and the second screen plate 9. The hydraulic cylinder 19 can be started. While the first slider 11 drives the pressure roller 14 to move, the hydraulic cylinder 19 drives the second slider 20 to move upward, and the second slider 20 drives the mounting plate 12 and the conical needle 13 to move upward to clear the waste blocked in the sieve holes, so that the first screen plate 6 and the second screen plate 9 can work normally, thereby extending the service life of the first screen plate 6 and the second screen plate 9.
