Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and in particular to an environmental protection device and method for construction engineering. Background Art

[0002] Construction project construction refers to the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment, including the entire process from project preparation, construction to project completion acceptance. At the construction site, the ground is usually exposed without effective coverage. When construction machinery and personnel are working on the ground, a lot of dust is easily raised, causing dust pollution. Various types of construction machinery are often required during the construction process, and these machines will generate a lot of dust during operation.

[0003] The large amount of dust generated during construction projects not only affects the air quality of the surrounding environment, but also harms the health of surrounding residents. Therefore, it is necessary to deal with the dust in the air and reduce the dust concentration in the air through dust reduction devices to achieve environmental protection. Reducing the dust concentration in the air can improve the air quality of the construction site and its surrounding environment, thereby protecting the health of construction workers and surrounding residents, and reducing the spread of dust, which helps protect soil resources in the ecological environment.

[0004] During use, existing dust reduction devices often achieve dust reduction through water spray or dust suction. Although they can handle dust and play an environmental role, the use effect is not good enough. The dust reduction method through water spray wastes water resources too much. The dust reduction method through dust suction makes the interior of the dust reduction device full of dust, which is cumbersome to clean. The work efficiency is not good enough, and the sewage from flushing the dust suction net cannot be used for dust reduction treatment. Summary of the invention

[0049] Specifically, the internal shape of the water flow block 102e is a cavity, and the water flow block 102e wraps multiple water outlets 102c, so that the sewage flowing out of the water outlets 102c enters the interior of the water flow block 102e, and the interior of the water flow block 102e fits tightly with the surface of the separation barrel 102b, preventing sewage from flowing from the connection between the water flow block 102e and the separation barrel 102b.

[0053] When the water level on the right side of the water tank 201a reaches the level sensor 201p, the second electrically controlled valve 201e is automatically stopped, and the first electrically controlled valve 201d is started, so that the water pump 201g pumps out the sewage on the left side of the water tank 201a through the water inlet pipe 201f, the first electrically controlled valve 201d and the pumping pipe 201c, thereby reusing the sewage. When it is necessary to discharge the sewage to reduce dust in the air, the first electrically controlled valve 201d is stopped, and the second electrically controlled valve 201e is started to pump out the remaining clean water on the right side of the water tank 201a, thereby cleaning the tank body. The inside of box 101b is flushed to keep the inside of box body 101b clean, saving the cleaning time of the staff.

The water pumped by water pump 201g enters the inside of L tube 202a through diverter valve 201j, and then is sprayed out from multiple dust reduction nozzles 202c through long tube 202b to achieve air dust reduction treatment.

[0054] When it is necessary to clean multiple material receiving blocks 104b, first remove the bolts fixing the two mounting blocks 104c to the separation barrel 102b, then move the two bending blocks 104a downward to disengage the multiple material receiving blocks 104b from the separation barrel 102b, and then move the two bending blocks 104a in opposite directions to disengage the two plug-in blocks 104d from the left bending block 104a, so that the multiple material receiving blocks 104b can be cleaned.

[0055] The movement of the movable plate 203a will cause the return spring 203c to deform. When the exhaust fan 101d stops running, the deformation of the return spring 203c causes the movable plate 203a to drive the protection block 203f, the movable plate 203g, the elastic spring 203h and the rotating plate 203j to automatically rebound to their original positions.

[0056] Reference Figures 1 to 11 , which is the third embodiment of the present invention, provides an air outlet component 103 and a flow control component 203.

[0059] The guide member 103c includes an air duct 103c1 and an air diffuser 103c2. The right side of the air duct 103c1 is fixedly connected to the top of the air collecting block 103a. The left side of the air duct 103c1 passes through the box body 101b and extends to the top inside the box body 101b. The left side of the surface of the air duct 103c1 is fixedly connected to the inside of the partition 101k, and the bottom of the air duct 103c1 is fixedly connected to the top of the air diffuser 103c2.

[0060] The guide member 103g includes a plurality of nozzles 103g1, a cavity tube 103g2 and a second air outlet pipe 103g3. The left sides of the plurality of nozzles 103g1 are fixedly connected to the right side of the cavity tube 103g2 and are evenly distributed. The bottom of the cavity tube 103g2 is fixedly connected to the left side of the second air outlet pipe 103g3. The cavity tube 103g2 is located on the left side of the dust suction port 101c. The right side of the second air outlet pipe 103g3 passes through the box body 101b and is fixedly connected to the left side of the annular tube 103e.

[0061] Specifically, the multiple air holes 103f all blow air in one direction and are inclined downward, so that the sewage inside the separation barrel 102b can be easily discharged through the multiple water outlet holes 102c under the action of the air flow. The top inside the movable plate 203a is slidingly connected to the surface of the air duct 103c1, and the multiple nozzles 103g1 are all inclined in shape. The wind direction blows to the surface of the dust suction port 101c, and the interior of the protective block 203f is in close contact with the surface of the flow control tube 201k to prevent water from flowing downward inside the flow control tube 201k.

[0062] Furthermore, during the operation of the exhaust fan 101d, the generated wind force will blow toward the movable plate 203a, causing the movable plate 203a to move to the right. The movement of the movable plate 203a will cause the protective block 203f and the movable plate 203g to move to the right. The movable plate 203g will drive the rotating plate 203j and the elastic spring 203h to move to the right. As the rotating plate 203j moves to the right, it will be squeezed by the two squeezing blocks 203k, causing the rotating plate 203j to rotate downward. As the angle of the rotating plate 203j rotates downward increases and the shape of the control block 203m increases, the water flow to the left inside the flow control tube 201k will increase, thereby achieving the water flow rate speed sprayed from the cleaning nozzle 201n controlled by the wind force.

[0063] When the exhaust fan 101d exhausts air to the right, the wind will continue to spray to the right, and then enter the interior of the air collecting block 103a through the movable plate 203a and the support plate 203d. The airflow inside the air collecting block 103a will form two airflows through the inclined plate 103b. The upward airflow will be discharged from the diffuser head 103c2 through the air duct 103c1, so as to facilitate the sewage after the dust is adsorbed to be blown downward and enter the interior of the separation barrel 102b through the discharge port 101h. The downward airflow will enter through the first air outlet pipe 103d. The sewage flows into the annular tube 103e and then enters the annular block 102d through the multiple air holes 103f. The shape and jetting of the multiple air holes 103f can speed up the discharge of sewage from the separation barrel 102b. Part of the airflow inside the annular tube 103e enters the interior of the cavity tube 103g2 through the second air outlet pipe 103g3 and then is ejected through the multiple nozzles 103g1. The gas ejected from the multiple nozzles 103g1 can guide the air, thereby facilitating dust suction at the suction port 101c.

[0064] It should be noted that the material of the first air outlet pipe 103d is a hard tube material, the material of the second air outlet pipe 103g3 is a hard tube material, and the material of the air duct 103c1 is a hard tube material.

[0065] The remaining structure is the same as that of Example 2.

[0066] Reference Figures 1 to 11, which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides an environmental protection device for construction engineering.

[0067] When dust reduction is required, the dust concentration in the air is first monitored by the dust sensor 101f, and the exhaust fan 101d is made to generate corresponding wind strength according to the dust concentration in the air, so as to suck the dust into the top of the box body 101b through the dust suction port 101c.

[0068] Before vacuuming, run the water pump 201g and the motor 102a, turn the diverter valve 201j, close the flow of the L tube 202a, and allow the internal flow control tube 201k to circulate. The water pump 201g first pumps out the water on the right side of the water tank 201a through the water inlet pipe 201f and the second electric control valve 201e, and allows the water to enter the diverter valve 201j through the first water outlet pipe 201h, and then enter the second water outlet pipe 201m through the flow control tube 201k, and finally spray out through the cleaning nozzle 201n. With the influence of wind, the dust is sprayed.

[0069] The sewage will enter the separation barrel 102b through the discharge port 101h. As the motor 102a runs, the separation barrel 102b will rotate, and the sewage entering the separation barrel 102b will be separated into solid and liquid under the continuous rotation of the separation barrel 102b. The sewage will flow upward and enter the water flow block 102e through multiple water outlet holes 102c. The sewage inside the water flow block 102e will enter the left side of the water tank 201a through the connecting pipe 102f, and the dust particles will enter the multiple receiving blocks 104b at the bottom of the separation barrel 102b, thereby collecting the dust particles.

[0070] When the exhaust fan 101d is in operation, the generated wind force will blow toward the movable plate 203a, causing the movable plate 203a to move to the right. The movement of the movable plate 203a will cause the protective block 203f and the movable plate 203g to move to the right. The movable plate 203g will drive the rotating plate 203j and the elastic spring 203h to move to the right. As the rotating plate 203j moves to the right, it will be squeezed by the two squeezing blocks 203k, causing the rotating plate 203j to rotate downward. As the angle of the rotating plate 203j rotating downward increases and the shape of the control block 203m increases, the water flow to the left inside the flow control tube 201k will increase, thereby achieving the control of the water flow rate sprayed from the cleaning nozzle 201n according to the wind force.

[0071] When the exhaust fan 101d exhausts air to the right, the wind will continue to spray to the right, and then enter the interior of the air collecting block 103a through the movable plate 203a and the support plate 203d. The airflow inside the air collecting block 103a will form two airflows through the inclined plate 103b. The upward airflow will be discharged from the diffuser head 103c2 through the air duct 103c1, so as to facilitate the sewage after the dust is adsorbed to be blown downward and enter the interior of the separation barrel 102b through the discharge port 101h. The downward airflow will enter through the first air outlet pipe 103d. The sewage flows into the annular tube 103e and then enters the annular block 102d through the multiple air holes 103f. The shape and jetting of the multiple air holes 103f can speed up the discharge of sewage from the separation barrel 102b. Part of the airflow inside the annular tube 103e enters the interior of the cavity tube 103g2 through the second air outlet pipe 103g3 and then is ejected through the multiple nozzles 103g1. The gas ejected from the multiple nozzles 103g1 can guide the air, thereby facilitating dust suction at the suction port 101c.

[0072] When the water level on the right side of the water tank 201a reaches the level sensor 201p, the second electrically controlled valve 201e is automatically stopped, and the first electrically controlled valve 201d is started, so that the water pump 201g pumps out the sewage on the left side of the water tank 201a through the water inlet pipe 201f, the first electrically controlled valve 201d and the pumping pipe 201c, thereby reusing the sewage. When it is necessary to discharge the sewage to reduce dust in the air, the first electrically controlled valve 201d is stopped, and the second electrically controlled valve 201e is started to pump out the remaining clean water on the right side of the water tank 201a, thereby cleaning the tank body. The inside of box 101b is flushed to keep the inside of box body 101b clean, saving the cleaning time of the staff. After the sewage enters the left side of the inside of water tank 201a, the first electrically-controlled valve 201d is started, the second electrically-controlled valve 201e is stopped, the diverter valve 201j is rotated, and the circulation of flow control tube 201k is closed to allow L tube 202a to circulate. The water pumped by water pump 201g enters the inside of L tube 202a through diverter valve 201j, and then is sprayed out from multiple dust reduction nozzles 202c through long tube 202b to achieve air dust reduction treatment.

[0073] When it is necessary to clean multiple material receiving blocks 104b, first remove the bolts fixing the two mounting blocks 104c to the separation barrel 102b, then move the two bending blocks 104a downward to disengage the multiple material receiving blocks 104b from the separation barrel 102b, and then move the two bending blocks 104a in opposite directions to disengage the two plug-in blocks 104d from the left bending block 104a, so that the multiple material receiving blocks 104b can be cleaned.

[0074] The movement of the movable plate 203a will cause the return spring 203c to deform. When the exhaust fan 101d stops running, the deformation of the return spring 203c causes the movable plate 203a to drive the protection block 203f, the movable plate 203g, the elastic spring 203h and the rotating plate 203j to automatically rebound to their original positions.

[0075] In summary, the mobile dust suction component 101 absorbs dust in the air, and the inhaled dust is sprayed through the cleaning component 201. The solid-liquid separation component 102 can reuse the sewage for many times to increase the duration of dust reduction. The used sewage can be sprayed on the air through the dust reduction component 202 to save water resources. The separated dust particles can be collected through the impurity collection component 104, and the flow of sewage can be accelerated through the air outlet component 103, and the dust suction effect of the dust suction port 101c can be improved. The flow control component 203 can control the flow rate of water sprayed from the cleaning nozzle 201n according to the wind strength of the exhaust fan 101d.
