[0019] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0020] like Figure 1 , Figure 2 and Figure 3As shown, a waste treatment device for civil engineering construction provided by an embodiment includes a hollow base 1, the front end of the base 1 is open, a connected crushing box 2 is arranged above the base 1, two crushing rollers 21 are arranged in the crushing box 2, a lower hopper 3 is arranged on the top of the crushing box 2, and a door is arranged in the front opening of the base 1. The door consists of an upper door plate 11 and a lower door plate 12 arranged vertically, and the bottom end of the upper door plate 11 and the top end of the lower door plate 12 are hinged to close the opening;

[0021] An opening 22 is provided on the top wall of the base 1 to communicate with the crushing box 2, and the opening 22 is located directly below the gap between the two crushing rollers 21;

[0022] Two inclined plates 23 are arranged on the top of the base 1. The two inclined plates 23 are located at the front and rear ends of the opening 22 and are used to guide the crushed garbage into the opening 22. The top ends of the two inclined plates 23 are far away from each other and the bottom ends are close to each other.

[0023] A horizontal sealing plate 14 is provided below the top wall of the base 1 and can move in the horizontal direction. The sealing plate 14 is located on the side of the opening 22 close to the open opening. A connecting rod 111 is rotatably provided at the front end of the sealing plate 14. The end of the connecting rod 111 away from the sealing plate 14 is rotatably connected to the lower inner part of the upper door panel 11.

[0024] The base 1 is provided with an air duct 4 communicating with the outside, and a fan 5 is provided on the air duct 4 to provide negative pressure inside the base 1 .

[0025] A horizontal support rod 141 is fixedly set below the top wall of the base 1. There are preferably two support rods 141, which are respectively located on the left and right sides below the top wall of the base 1. The support rod 141 extends along the front-to-back direction of the base 1. The sealing plate 14 is located between the support rod 141 and the top wall of the base 1. The support rod 141 is used to support the weight of the sealing plate 14.

[0026] A horizontal hanging rod 13 is arranged at the front end of the top wall of the base 1 , and a hanging ring 121 is arranged at the bottom of the outer side of the lower door panel 12 .

[0027] A water pool 6 is arranged at the rear end of the base 1 , and the air outlet of the air duct 4 is located below the liquid level inside the water pool 6 .

[0028] The air duct 4 has a vertical section 41 . The air duct 4 is connected to the inside of the base 1 through the vertical section 41 . A filter is disposed on the upper inner side of the vertical section 41 .

[0029] like Figure 4 As shown, two vertical slide rails 7 are arranged on the inner side wall of the base 1 at both sides of the opening, and convex rods are arranged at the bottom of the left and right side walls of the lower door panel 12, and the two convex rods are located in the two slide rails 7.

[0030] When the present application is in use, the fan 5 is first started to provide negative pressure inside the base 1, the open door is closed, and garbage is fed into the lower hopper 3. At this time, the lower hopper 3 is connected with the base 1, so the lower hopper 3 has negative pressure. After the garbage is crushed, it enters the base 1 through the opening 22. The dust generated by the crushing is sucked into the vertical section 41 by the air duct 4. The large pieces of debris entering therein are intercepted by the filter screen, and the dust continues to be sent along the air duct 4 into the water pool 6 to mix with water, and the dust therein is adsorbed by water. Specifically, a sand head can be set at the air outlet of the air duct 4.

[0031] When it is necessary to clean the garbage inside the base 1, the lower hopper 3 stops feeding the garbage, lifts the upper door panel 11 and the lower door panel 12, and moves the top end of the lower door panel 12 and the bottom end of the upper door panel 11 toward the inside of the base 1, so that the door bends inward from the middle, and then further lifts the bottom end of the lower door panel 12, so that the upper door panel 11 and the lower door panel 12 are both rotated to a horizontal state, and the hanging ring 121 is hung on the L-shaped hanging rod 13. During this process, the sealing plate 14 moves toward the opening 22 and closes the opening 22, and the garbage in the base 1 is taken out from the front opening. At this time, the front opening is in a negative pressure state, so dust will not overflow from the opening, and then the door is moved in the opposite direction to close the opening, the sealing plate 14 is removed from the opening 22, and the lower hopper 3 returns to a negative pressure state.

[0032] It should be noted that the water pool 6 is only a method for treating the dust in the air outlet, and can also be replaced by dust removal devices such as dust removal bags in the prior art.

[0033] When the filter is clogged, the water in the pool 6 is cleared, and the fan 5 is started for back-blowing, so that the clogged material on the filter can be discharged vertically downward, and then new water is filled into the pool 6.

[0034] In the present application, the hanging ring 121 can also be replaced by a rope, and the rope can be tied to the hanging rod 13 after the door is opened.

[0035] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
