Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, and more specifically to sand and stone screening equipment for building construction. Background Art
[0002] In the process of construction, sand and gravel screening equipment is usually needed to obtain materials of suitable particle size for construction. However, the existing screening equipment usually generates a lot of dust during screening, which is easily inhaled by workers, causing harm to their health and is not conducive to environmental protection requirements.
[0003] For example, the patent with publication number CN216368867U discloses an anti-dust and sand screening device for construction, which relates to the technical field of sand screening devices. The utility model includes a sand screening box, and an anti-dust component and a sand screening component are arranged inside the sand screening box. The anti-dust component includes a fixed frame, a sponge block and a water inlet pipe. The fixed frame is arranged inside the sand screening box, and the sponge block is engaged inside the fixed frame. One end of the water inlet pipe is fixedly connected to the fixed frame and communicated with the inside of the fixed frame. The top of the water inlet pipe passes through the interior of the sand screening box and extends to the outside of the sand screening box. The sand screening component includes a first screen, a second screen, a rubber pad, a vibration motor, a driving component, a spring and a support frame.
[0004] The above patent absorbs dust by setting up an anti-dust component, thereby preventing dust from floating in the air and polluting the environment. However, in actual use, the above patent absorbs dust by a wet sponge block. However, after the sponge block absorbs a certain amount of dust, the hydrophobic holes of the sponge will be blocked, so that the water in the water pipe can only continue to moisten a part of the sponge, thereby affecting the dust absorption effect.
[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a sand and gravel screening equipment for construction is provided, in order to achieve a more practical purpose. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a sand and stone screening device for construction to solve the problems existing in the above-mentioned background technology.
[0007] The utility model provides the following technical solutions: a sand and gravel screening equipment for construction, comprising a sand screening box and a control panel, the side wall of the sand screening box is provided with a through hole, a vacuum cleaner is fixedly installed on the inner wall of the through hole of the sand screening box, one side of the through hole of the sand screening box is connected with a connecting pipe by screws, the other end of the connecting pipe is connected with an ash collecting box by screws, the ash collecting box is fixedly connected to the side wall of the sand screening box, a plurality of ventilation holes are evenly provided on the upper end surface of the ash collecting box, a sewage outlet is provided at the bottom end of the ash collecting box, and a manual valve is installed at the sewage outlet.

One end of the rotating shaft is rotatably connected to the inner wall of the ash collecting box, and a number of stirring blades are evenly installed on the outside of the ash collecting box. The stirring blades are used to stir the dust on the water body inside the ash collecting box to prevent the dust from being difficult to be soaked under the tension of the water, resulting in dust accumulation and then being discharged from the vent under the action of the airflow.
[0009] Furthermore, the bottom end of the ash collecting box is set to be conical. By setting the bottom end of the ash collecting box to be non-conical, it is avoided that the dust deposited at the bottom of the device is difficult to be discharged when the ash collecting box discharges sewage externally.
[0010] Furthermore, sealing rings are provided at both ends of the connecting pipe, and the sealing rings are used to seal the two ends of the connecting pipe to prevent dust transmitted through the connecting pipe from seeping out from the connecting gap and causing pollution to the external environment.
