Description

Technical Field

[0001] The utility model relates to the technical field of construction dust removal, in particular to a construction dust removal device. Background Art

[0002] During the road construction process, dust of different sizes will inevitably be generated. The dust not only affects the normal construction of the workers, but also pollutes their working environment. Therefore, dust removal equipment is needed to carry out dust removal operations.

[0003] The prior art generally uses fog cannons or dust suction devices to remove dust. For dust in a larger area, fog cannons are generally used for dust removal. The fog cannon sprays water mist to places with more dust, and the water mist mixes with the dust and settles to achieve a dust removal effect. However, the dust removal method of the fog cannon is also likely to affect the staff's line of sight, and the combined sedimentation of water mist and dust will pollute the ground; for dust in a smaller area, such as in scenes with high frequency of drilling or digging pits on the road, if a fog cannon is used for dust removal, it will affect the line of sight of drilling or digging pits, and will also waste water resources. Therefore, dust removal is generally performed through a dust suction device. The dust suction device sucks dust in the air into a dust removal box, and settles it in the dust removal box. It will not produce stains on the ground and will not affect the work of the staff, but its dust removal range is limited.

[0004] The above-mentioned fog cannon or dust suction device are independent equipment with a relatively single dust removal function. During road construction, the dust generated during the construction process varies depending on the construction work. If only one of the equipment is used, the dust removal requirements cannot be met. If two dust removal equipment are used at the same time, it not only takes up space, but also increases the dust removal cost. Utility Model Content

[0005] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a dust removal device for construction.

[0006] The technical solution of this utility model is as follows:

[0007] A construction dust removal device comprises a movable base, on which a dust suction mechanism and a spray mechanism are arranged;

[0008] The dust collection mechanism includes a dust removal head, a dust collection pipe group and a dust collection box which are connected in sequence. The angle of the dust removal head is adjustable. The dust collection box has an air inlet which is connected to one end of the dust collection pipe group for air intake. The dust collection box is provided with a plurality of first dust removal nozzles located above the air inlet. The nozzles of the first dust removal nozzles are arranged downward.

[0009] The spray mechanism includes a water tank and a plurality of second dust removal nozzles distributed along the circumferential direction outside the dust removal head. The plurality of second dust removal nozzles are connected to the water tank through pipes with valves. The second dust removal nozzles are connected to the first dust removal nozzles through copper drum water pipes with valves.

[0010] The dust suction mechanism and the spray mechanism can quickly switch to the appropriate dust removal mode according to the different ranges of dust environments generated by different construction operations. For a larger dust environment, water mist is sprayed through the second dust removal nozzle of the spray mechanism, and the water mist is blown to the designated direction through the dust removal head with a blowing function to achieve dust removal. For a small-scale dust environment, the dust suction mechanism is started, and the dust is sucked into the dust removal box through the dust removal head for sedimentation to achieve dust removal. The dust removal method is flexible and changeable, and also greatly reduces the occupied space.

[0011] Regarding the specific structure of the dust suction tube group, the dust suction tube group includes a hard tube and a soft tube that are connected to each other. The end of the hard tube away from the soft tube is connected to the dust removal head, and the end of the soft tube away from the hard tube is connected to the dust removal box. A first angle adjustment component is provided under the hard tube, and the angle of the dust removal head can be adjusted by the first angle adjustment component.

[0012] The structure of the above-mentioned first angle adjustment component is that the first angle adjustment component includes an arc-shaped slide rail and a slider. The arc-shaped slide rail is arranged on the base. The upper end of the slider is hinged to one end of the hard tube close to the dust removal head, and the lower end is slidably connected to the arc-shaped slide rail, so that the dust removal head can move along the slide direction of the arc-shaped slide rail to achieve horizontal angle adjustment and increase the range of water mist spraying.

[0013] Preferably, a lifting mechanism is connected below the end of the hard tube away from the dust removal head. The lifting mechanism is vertically arranged on the base. The upper end of its output shaft is hinged to the hard tube, and the axis of the output shaft coincides with the axis of the arc-shaped slide rail. The lifting mechanism can be used to control the up and down movement of the end of the hard tube connected to the dust removal head, thereby realizing the up and down angle adjustment of the dust removal head.

[0014] Regarding the specific structure of the dust removal head, the dust removal head is a conical structure, and a filter screen and a first forward and reverse fan are arranged on its inner conical surface from the outside to the inside. The first forward and reverse fan is a prior art, which can realize forward and reverse rotation. The forward rotation can cooperate with the second dust removal nozzle to blow air outward, and the reverse rotation can draw wind and cooperate with the dust suction mechanism to introduce dust into the dust removal box.

[0015] The dust box needs to be cleaned regularly to ensure that the air inlet is not blocked. In order to facilitate the quick cleaning of the dust box and achieve continuous dust removal, the water tank and the dust box are connected through a connecting pipe with a valve. The connecting pipe can inject clean water into the dust box when the inner wall of the dust box needs to be cleaned.

[0016] The beneficial effect of the utility model is that the dust suction mechanism and the spray mechanism can select the appropriate dust removal mode according to the size of the dust range of the construction phenomenon, and it is not necessary to equip a variety of dust removal equipment, which reduces the occupied space. For a construction environment with a large range of dust, the dust removal mode of the dust suction mechanism has limited effect, and it is necessary to start the spray mechanism for dust removal, control the second dust removal nozzle to spray water mist, and the dust removal head has a blowing function. The dust removal head blows the water mist to a designated position, and by adjusting the angle of the dust removal head, dust is further accurately removed in areas with more dust and a larger range.

[0017] For construction environments with relatively large dust, such as construction sites that generate dust such as drilling and digging, the dust can be removed by starting the dust suction mechanism. The dust removal head has a suction function to suck the dusty air into the dust removal box. The first dust removal nozzle sprays water mist. The dust in the dust removal box combines with the water mist to settle, achieving a dust removal effect, which can reduce dust pollution to the environment, reduce the situation where dust blocks the workers' working vision, and also reduce pollution to the ground; quickly switch the most suitable dust removal equipment according to different construction environments to facilitate the rapid construction of roads or construction projects;

[0018] The dust removal head can move along the slide direction of the arc-shaped slide rail to achieve horizontal angle adjustment. The lifting mechanism can control the end of the hard tube connected to the dust removal head to move up and down, thereby achieving up and down angle adjustment of the dust removal head and increasing the range of water mist spraying.

The nozzles of the first dust removal nozzles 6 are arranged toward the air inlet. A sewage pipe is provided at the bottom of the dust removal box 3 for discharging a mixture of water mist and dust.

[0032] See also Figure 1 and Figure 2 As shown, the structure of the first angle adjustment component is that the first angle adjustment component includes an arc-shaped slide rail 11 and a slider 12. The arc-shaped slide rail 11 is arranged on the base 1. The upper end surface of the arc-shaped slide rail 11 is provided with a slideway 111. The upper end of the slider 12 is hinged to the end of the hard tube 4 close to the dust removal head 2 through a hinge shaft. The axis of the hinge shaft is vertically arranged to the axis of the hard tube.
