Description

Technical Field

[0001] The present invention relates to the technical field of dust control, and more specifically, to a device and method for controlling dust during construction. Background Art

[0002] During construction, earthwork, demolition, concrete pumping and other construction activities disturb the ground and generate a large amount of dust. The fine particles in the dust have a serious impact on air quality and may cause respiratory diseases, especially among residents and workers around the construction site. In addition, many local laws and regulations require construction units to take measures to control dust to avoid environmental pollution and legal liability.

[0003] In the prior art, most of the dust is treated by using fog cannons. The principle is that the fog cannon guides the water mist through the airflow, so that the water mist is sprayed to the dust area, and the water mist absorbs the dust. However, in this process, the effective spray range of a single fog cannon is limited, and it is difficult to effectively control the dust. Although multiple fog cannons can ensure uniform spraying of water mist in a larger area, thereby effectively controlling the dust, the simultaneous operation of multiple fog cannons not only increases energy consumption and the cost of dust control, but also increases the difficulty of deployment and the labor intensity of the staff. In view of this, we propose a construction dust control device and method. Summary of the invention

[0013] A construction dust control method, the control method adopts the construction dust control device mentioned above to control, the method comprises the following steps:

[0014] S1: Determine the construction area: According to the conditions of the construction site, determine the area that needs to be dust-removed and divide the area reasonably;

[0015] S2: Device deployment: Deploy the equipment according to the results of the construction area division, and move the barrel into the construction area through the base according to the specific conditions of the construction area;

[0016] S3: Configure water supply system: Configure water supply pipelines and water source storage equipment in the construction area to continuously and stably provide high-pressure water source for water collection rings and atomizing nozzles to meet the water demand during dust control;

[0017] S4: Dust control: The atomizing nozzle sprays water mist in real time through the water supply system, and controls the operation of the first motor so that the fan blades guide the external airflow into the barrel and then discharge it from the airflow channel. By controlling the operation of the second motor, the state of the airflow being discharged from the airflow channel formed by the outer guide ring and the inner guide ring can be controlled, so that the trumpet shape formed when the airflow is discharged can be controlled, so that the airflow discharged from the airflow channel will wrap the construction area in a trumpet shape, and the momentum and pressure difference of the discharged airflow can suck in the surrounding water mist and keep it in the airflow, so that the airflow drives the water mist to wrap the dust, thereby increasing the dust control effect.

[0018] S5: Monitor construction results: During the construction process, monitor the air quality in the construction area and the feedback from construction workers to monitor the dust removal effect in real time. If the dust removal effect is not good or there are problems, adjust the spray angle, spray range and spray intensity in time to achieve the best dust removal effect to ensure the maximum dust removal effect.

[0019] S6: Maintenance and care: After the construction is completed, clean and maintain the inside of the barrel and its internal components to ensure the normal operation of the whole in the later stage and extend the service life, and clean the atomizing nozzle regularly to prevent blockage and wear.

[0020] Preferably, in the above step S4, before dust treatment, the state of the airflow and water mist being discharged is contracted into a columnar shape, and then gradually expanded until the dust area is wrapped therein, so as to achieve infiltration of the surface of the dust area and reduce dust.

[0021] Preferably, in the above-mentioned step S4, after the dust is treated, the trumpet shape formed by the airflow and water mist is gradually reduced, so that the water mist gradually wraps and shrinks the dust in the dust area until the water mist forms a column, thereby gradually and comprehensively suppressing the dust in the construction area, and preventing the dust in the middle of the trumpet shape formed by the airflow and water mist from being unable to be treated and escaping.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention continuously sprays water mist through the atomizing nozzle, guides the external airflow to the inside of the barrel through the fan blades, and then discharges it through the airflow channel formed by the outer guide ring and the inner guide ring, and the inside of the airflow channel gradually expands from the inlet to the outlet to form a trumpet shape, so that when the airflow is discharged from the airflow channel to the construction area, the airflow as a whole will be in a trumpet shape to wrap the construction area, and the momentum and pressure difference of the discharged airflow can inhale the surrounding water mist and keep it in the airflow, so that the airflow drives the water mist to wrap the dust, so that when the dust escapes, the water mist can block the dust, thereby preventing the dust from being raised.

[0024] The water mist will not pollute the environment, and because it forms a trumpet shape, it can greatly increase the area for dust treatment, thereby increasing the treatment effect.

[0025] 2. The present invention sets a second motor so that the operation of the second motor can control the state of the airflow discharged from the airflow channel formed by the outer guide ring and the inner guide ring, so as to control the trumpet shape formed when the airflow is discharged, and realize the gradual contraction and expansion of the airflow from the trumpet shape. In this way, in the early stage of dust treatment, the state of the airflow and water mist when discharged can be first shrunk into a columnar shape, and then gradually expanded until the dust area is wrapped therein, thereby realizing the infiltration of the surface of the dust area and reducing dust. After construction, the trumpet shape formed by the airflow and water mist is gradually reduced, so that the water mist gradually wraps and contracts the dust in the dust area until the water mist forms a columnar shape, thereby gradually and comprehensively suppressing the dust in the construction area, preventing the dust in the middle of the trumpet shape formed by the airflow and water mist from being unable to be treated and escaping, thereby completing the comprehensive control of the dust.

[0026] 3. The guide plates in the present invention are all spiral structures, so that the guide plates can not only connect the inner frame and the outer frame through the outer guide rails and the inner guide rails, but also when the airflow flows in the airflow channel, the spiral guide plates will guide the airflow, so that the airflow will spiral, so that when the airflow drives the water mist to wrap the dust area, the water mist can spirally wrap the dust area, thereby increasing the effect of dust control.

[0027] 4. In the present invention, since the guide plate is respectively connected to the outer guide rail and the inner guide rail in a sliding manner, when the airflow is guided by the guide plate, the guide plate will start to rotate on the outer guide rail and the inner guide rail due to the force generated by the push of the airflow, thereby causing the guide plate to rotate in a circular manner, thereby increasing the guiding effect of the guide plate on the airflow, thereby increasing the spiral effect of the airflow when it is discharged from the airflow channel, thereby further increasing the effect of controlling dust.

[0042] The adjustment assembly includes an adjustment cover 15, which is fixedly connected to one end of the bearing plate 7 away from the second motor 14, and the inner wall of the adjustment cover 15 is slidably connected to an adjustment plate 16, and a screw 17 is fixedly connected to the main shaft end of the second motor 14, and the other end of the screw 17 passes through the adjustment plate 16 and is threadedly connected thereto, and the outer wall of the adjustment cover 15 is provided with a plurality of adjustment grooves 18 corresponding to the inner skeleton 11, and the inner wall of the adjustment groove 18 is slidably connected to a slider 19, and the outer wall of the slider 19 is fixedly connected to the outer wall of the adjustment plate 16, and the other end of the slider 19 is hinged to a connecting rod 20, and the other end of the connecting rod 20 is hinged to the outer wall of the inner skeleton 11.

[0043] Specifically, by controlling the operation of the second motor 14, the second motor 14 drives the screw 17 to rotate, so that the rotation of the screw 17 drives the adjustment plate 16 to move in the adjustment cover 15, and the adjustment plate 16 will drive the slider 19 to move together when moving, and the slider 19 will push the inner skeleton 11 through the connecting rod 20 during the movement, and the inner skeleton 11 is connected to the outer skeleton 10 through the guide plate 12, and the outer skeleton 10 is hinged to the inner wall of the barrel 2, so that when the inner skeleton 11 is pushed and twisted, it will drive the outer skeleton 10 to twist together, so that the outer skeleton 10 and the inner skeleton 11 push and guide the outer guide ring 9 and the inner guide ring 8 made of rubber material during the twisting process, thereby controlling the airflow channel formed by the outer guide ring 9 and the inner guide ring 8. state, thereby controlling the state of the airflow discharged from the airflow channel, so as to control the trumpet shape formed when the airflow is discharged, and gradually shrink and expand the airflow from the trumpet shape, so that in the early stage of dust treatment, the state of the airflow and water mist when discharged can be shrunk into a columnar shape, and then gradually expanded until the dust area is wrapped inside, thereby realizing the infiltration of the surface of the dust area and reducing dust, and after construction, the trumpet shape formed by the airflow and water mist is gradually reduced, so that the water mist gradually wraps and shrinks the dust in the dust area until the water mist forms a columnar shape, thereby gradually and comprehensively suppressing the dust in the construction area, preventing the dust in the middle of the trumpet shape formed by the airflow and water mist from being unable to be treated and escaping, thereby completing the comprehensive control of dust.

[0044] Furthermore, the guide plates 12 are all spiral structures, and the spiral directions of the guide plates 12 are the same.

[0045] Specifically, the guide plates 12 are all spiral structures, so that the guide plates 12 can not only connect the inner frame 11 and the outer frame 10 through the outer guide rails 21 and the inner guide rails 22, but also when the airflow flows in the airflow channel, the spiral guide plates 12 will guide the airflow, causing the airflow to spiral, so that when the airflow drives the water mist to wrap the dust area, the water mist can spirally wrap the dust area, thereby increasing the effect of dust control.

[0050] like Figure 6 As shown, a construction dust control method is provided, wherein the construction dust control device described above is used for control, and the method comprises the following steps:

[0053] S3: Configure water supply system: Configure water supply pipelines and water source storage equipment in the construction area to continuously and stably provide high-pressure water source for the water collection ring 5 and the atomizing nozzle 6 to meet the water demand during dust control;

[0054] S4: Dust control: The atomizing nozzle 6 sprays water mist in real time through the water supply system, and controls the operation of the first motor 3 so that the fan blades 4 guide the external airflow to the inside of the barrel 2 and then discharge it from the airflow channel. By controlling the operation of the second motor 14, the state of the airflow being discharged from the airflow channel formed by the outer guide ring 9 and the inner guide ring 8 can be controlled, so that the trumpet shape formed when the airflow is discharged can be controlled, so that the airflow discharged from the airflow channel will wrap the construction area in a trumpet shape, and the momentum and pressure difference of the discharged airflow can suck in the surrounding water mist and keep it in the airflow, so that the airflow drives the water mist to wrap the dust, thereby increasing the dust control effect.

[0055] S5: Monitor construction results: During the construction process, monitor the air quality in the construction area and the feedback from construction workers to monitor the dust removal effect in real time. If the dust removal effect is not good or there are problems, adjust the spray angle, spray range and spray intensity in time to achieve the best dust removal effect to ensure the maximum dust removal effect.

[0057] In the above step S4, before the dust treatment, the state of the airflow and water mist being discharged is contracted into a columnar shape, and then gradually expanded until the dust area is wrapped therein, so as to achieve the infiltration of the surface of the dust area and reduce the dust.

[0058] In the above step S4, after the dust is treated, the trumpet shape formed by the airflow and the water mist is gradually reduced, so that the water mist gradually wraps and shrinks the dust in the dust area until the water mist forms a column, thereby gradually and comprehensively suppressing the dust in the construction area, and preventing the dust in the middle of the trumpet shape formed by the airflow and the water mist from being unable to be treated and escaping.

[0059] Working principle: This embodiment provides a construction dust control device, in which a water supply pipeline and a water source storage device are arranged in the construction area to continuously and stably provide a high-pressure water source for the water collecting ring 5 and the atomizing nozzle 6 (the water supply pipeline and the water source storage device are existing well-known technical solutions, which are irrelevant to the innovative technical points of the present invention, and therefore are not marked in the accompanying drawings), and the water collecting ring 5 continuously sprays water mist through the atomizing nozzle 6, and the operation of the first motor 3 drives the fan blades 4 to rotate, so that the fan blades 4 guide the external airflow to the inside of the barrel 2, and then the airflow formed by the outer guide ring 9 and the inner guide ring 8 The air is discharged from the air channel, and the interior of the air channel gradually expands from the inlet to the outlet to form a trumpet shape. This makes the air flow, when discharged from the air channel to the construction area, wrap the construction area in a trumpet shape as a whole, and the momentum and pressure difference of the exhaust air flow can suck in the surrounding water mist and keep it in the air flow, so that the air flow drives the water mist to wrap the dust inside, so that the water mist can block the dust when the dust escapes, thereby preventing the dust from escaping and polluting the environment. In addition, since the water mist forms a trumpet shape, the area for dust treatment can be greatly increased, thereby increasing the treatment effect.
