Dust falling device for atmospheric environment treatment

Abstract

This utility model relates to the field of atmospheric environmental governance technology and discloses a dust suppression device for atmospheric environmental governance. The device includes a base, with a liquid storage tank fixedly installed on the top of the base. A mist cannon and an air inlet pipe are respectively installed on the top of the liquid storage tank. The air outlet of the air inlet pipe is connected to the air inlet of the mist cannon. A high-pressure pump is embedded in the lower side of the liquid storage tank, and the liquid inlet of the high-pressure pump is connected to the inner cavity of the liquid storage tank. This dust suppression device for atmospheric environmental governance, through the inclusion of a cleaning component, utilizes the wind power generated by a fan to drive the wind-receiving blades to rotate, which in turn drives the shaft to rotate. The abutment on the shaft slides on the corrugated surface of the cylinder, pushing the dust filter screen to reciprocate along the guide slide rod, generating a vibration effect.

Description

Technical Field

[0001] This utility model relates to the field of atmospheric environmental governance technology, and more specifically to a dust suppression device used for atmospheric environmental governance. Background Technology

[0002] Atmospheric pollution control is a crucial issue in the field of environmental protection. With rapid industrialization and urbanization, dust pollution in the atmosphere has become increasingly serious, significantly impacting people's health and living environment. Therefore, in densely populated areas such as towns and cities, vehicle-mounted fog cannons are often used to suppress dust in the atmosphere.

[0003] A search revealed an existing patent (publication number: CN220176438U) that discloses a dust suppression device for atmospheric environmental governance. During use, the device utilizes a treatment box and filter design. A fan assists in the airflow within the treatment box, which is then filtered by two filter frames. This allows for reprocessing of the environment after treatment by a fog cannon, improving the overall atmospheric environmental governance effect and achieving finer processing. A water pump draws liquid and assists in atomizing nozzles to spray, further processing the flowing air and enhancing the atmospheric governance effect. Thanks to the design of the cleaning assembly, a servo motor drives a cleaning brush to rotate, cleaning the filter and preventing clogging, thus ensuring effective filtration. However, the inventors discovered the following problem with the existing technology during the development of this invention: The aforementioned dust suppression device uses a servo motor to drive a rotating cleaning brush for cleaning the filter. This method leads to wear and tear between the cleaning brush and the filter during continuous use. If the filter is damaged, the dust filtration effect will be compromised. If the cleaning brush wears down, it will reduce the cleaning effect on the dust filter, which will affect the normal operation of the entire dust suppression device and reduce the dust suppression efficiency. In addition, the servo motor, as a power source, consumes a certain amount of electricity during operation, which increases the operating cost of the device.

[0004] In view of this, this utility model proposes a dust suppression device for atmospheric environmental management to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dust suppression device for atmospheric environmental governance, so as to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a dust suppression device for atmospheric environmental governance, including a base, a liquid storage tank fixedly installed on the top of the base, a fog cannon and an air inlet pipe respectively installed on the top of the liquid storage tank, the air outlet of the air inlet pipe being connected to the air inlet of the fog cannon, a high-pressure pump embedded in the lower side of the liquid storage tank, the liquid inlet of the high-pressure pump being connected to the inner cavity of the liquid storage tank, the liquid outlet of the high-pressure pump extending through a pipe to the inner cavity of the fog cannon and being connected to the built-in atomizing nozzle arranged in a ring, a fan installed on the inner wall of the air inlet pipe, the air outlet of the fan facing the fog cannon, a dust filter screen installed on the inner wall of the air inlet pipe on the air inlet side of the fan, and a cleaning component installed between the air inlet pipe and the dust filter screen.

[0007] The cleaning assembly includes a shaft rotatably mounted on the inner wall of the air inlet duct. The shaft is located on the side of the dust filter screen near the fan, and the central axes of the shaft and the air inlet duct are parallel. Several wind-receiving blades are fixedly installed in a circumferential array at the end of the shaft near the fan, and a stop rod is fixedly installed at the end of the shaft near the dust filter screen. Two guide slide rods are symmetrically fixedly installed on the inner wall of the air inlet duct. The dust filter screen is slidably mounted on the surface of the guide slide rods. A cylinder is fixedly installed on the surface of the dust filter screen. The central axis of the cylinder coincides with that of the shaft. A corrugated groove is opened at the end of the cylinder near the shaft, and the stop rod is positioned corresponding to the corrugated groove. The surfaces of the stop rod and the cylinder are both treated with wear-resistant materials. The rotation of the shaft causes the stop rod to slide on the surface of the corrugated groove.

[0008] Furthermore, the upper end of the dust filter is inclined toward the air inlet of the air inlet pipe, and a dust discharge port is opened on the bottom side of the air inlet pipe corresponding to the dust filter. A dust collection box is fixedly installed on the bottom side of the air inlet pipe corresponding to the dust discharge port.

[0009] As a further description of the above technical solution: by setting the dust filter screen at an angle on the inner wall of the air inlet pipe, and setting the dust discharge port and dust collection box at the bottom of the air inlet pipe, the dust can be collected during the vibration of the dust filter screen.

[0010] Furthermore, a cleaning port is provided at the bottom of the dust collection box, and a cleaning plate is detachably installed on the surface of the dust collection box corresponding to the cleaning port by bolts.

[0011] As a further description of the above technical solution: After the device is used, the dust inside the dust collection box can be easily cleaned by opening the cleaning plate.

[0012] Furthermore, a return spring is sleeved on the surface of the guide slide rod. The left and right ends of the return spring abut against the inner wall of the air inlet pipe and the surface of the dust filter, respectively. The return spring drives the dust filter to move to the right, so that the abutment rod quickly returns to its original position and abuts against the wave groove at the end of the cylinder.

[0013] As a further description of the above technical solution: by setting the reset spring, it is possible to ensure that the dust filter screen is quickly reset, so that the push rod and the wave groove are kept in a tight abutment state, ensuring the continuous and effective operation of the cleaning component.

[0014] Furthermore, mounting feet are fixedly installed on the surface of the base, and mounting holes are reserved on the surface of the mounting feet. The mounting holes are used to insert bolts for installation and fixation with the external vehicle body. A control panel is fixedly installed on the outer wall of the liquid storage tank, and the control panel is electrically connected to the cab of the external vehicle through wires.

[0015] As a further description of the above technical solution: by setting up mounting feet and mounting holes, the dust suppression device can be easily installed and fixed on the external vehicle compartment, facilitating vehicle-mounted mobile operation and flexibly responding to the dust suppression needs of different areas, greatly improving the ease of use and applicability of the device; at the same time, the control panel is electrically connected to the external vehicle cab, allowing operators to control the device from inside the cab, such as controlling the start and stop of the fog cannon and adjusting the working pressure of the high-pressure pump, further improving the ease of operation and intelligence of the device.

[0016] Furthermore, a liquid level sensor is fixedly installed on the inner wall of the liquid storage tank. The liquid level sensor is connected to the driver's cab of an external vehicle via a control panel. A replenishment valve and a drain valve are respectively embedded on the top and bottom sides of the liquid storage tank.

[0017] As a further description of the above technical solution: by setting up a liquid level sensor, the liquid level in the storage tank can be monitored in real time, and the liquid level information can be transmitted to the driver's cab of the external vehicle through the control panel, so that the operator can know the amount of water in the storage tank in time and avoid affecting the dust suppression effect due to insufficient water. At the same time, the setting of liquid replenishment valve and drain valve facilitates the replenishment and draining of the storage tank, ensuring the continuous and stable operation of the device.

[0018] Furthermore, a metal protective mesh is provided at the air inlet end of the air inlet pipe.

[0019] As a further description of the above technical solution: by installing a metal protective mesh at the air inlet end of the air inlet duct, large particles of debris can be effectively prevented from entering the air inlet duct and causing damage to the fan and dust filter.

[0020] The technical effects and advantages of this utility model are as follows: 1. The dust suppression device used in this atmospheric environmental control utilizes a high-pressure pump to deliver water from a storage tank to an atomizing nozzle, forming a water mist that is then sprayed out. A fan drives the airflow to propel the water mist to the outside, achieving dust suppression through the water mist. During this process, a dust filter screen filters the air entering the air inlet duct. By incorporating a cleaning component, the fan-generated airflow drives the blades to rotate, which in turn rotates the shaft. The abutment on the shaft slides on the corrugated surface of the cylinder, pushing the dust filter screen to reciprocate along the guide rail, generating a vibration effect. This causes the dust adhering to the surface of the dust filter screen to fall off during the vibration, thus maintaining the permeability of the dust filter screen. This design eliminates the need for additional power sources such as servo motors, utilizing only the airflow generated by the device itself to achieve automatic cleaning of the dust filter screen. This effectively avoids the wear problem between the cleaning brush and the dust filter screen in traditional cleaning methods, extending the service life of the dust filter screen, ensuring the dust filtration effect, and reducing the operating cost of the device.

[0021] 2. The dust suppression device used in this atmospheric environmental control system has a dust filter screen installed at an angle on the inner wall of the air inlet duct, and a dust discharge port and a dust collection box are set at the bottom of the air inlet duct. During the vibration of the dust filter screen, dust can be collected. After the device is used, the dust collection box can be cleaned by opening the cleaning plate. The reset spring ensures that the dust filter screen can be quickly reset, keeping the push rod and the wave groove tightly pressed together, ensuring the continuous and effective operation of the cleaning components.

[0022] 3. The dust suppression device used in this atmospheric environmental control system is easily installed and fixed on an external vehicle compartment by means of mounting feet and mounting holes, facilitating mobile operation and flexibly responding to dust suppression needs in different areas, greatly improving the ease of use and applicability of the device. Simultaneously, the control panel is electrically connected to the driver's cab of the external vehicle, allowing operators to control the device from inside the cab, such as controlling the start and stop of the fog cannon and adjusting the working pressure of the high-pressure pump, further improving the device's operational convenience and intelligence. A liquid level sensor monitors the liquid level in the storage tank in real time and transmits the information to the driver's cab via the control panel, enabling operators to promptly understand the water level in the storage tank and avoid affecting the dust suppression effect due to insufficient water. The addition of a replenishment valve and a drain valve facilitates replenishment and draining of the storage tank, ensuring the continuous and stable operation of the device. A metal protective mesh at the air inlet end of the air inlet pipe effectively prevents large particles of debris from entering the air inlet pipe and damaging the fan and dust filter, further extending the device's service life and improving its reliability and stability.

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The dust suppression device for atmospheric environmental governance involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Reference Figures 1 to 5 This utility model provides a dust suppression device for atmospheric environmental management, including a base 1, and a liquid storage tank 2 is fixedly installed on the top of the base 1.

[0027] The surface of the base 1 is fixedly equipped with mounting feet 18, and the surface of the mounting feet 18 is provided with mounting holes 19. The mounting holes 19 are used to insert bolts for installation and fixation with the external vehicle body. The outer wall of the liquid storage tank 2 is fixedly equipped with a control panel 20, which is electrically connected to the cab of the external vehicle through wires.

[0028] By setting up mounting feet 18 and mounting holes 19, the dust suppression device can be easily installed and fixed on the external vehicle body, facilitating vehicle-mounted mobile operations. This allows for flexible responses to dust suppression needs in different areas, greatly improving the ease of use and applicability of the device. At the same time, the control panel 20 is electrically connected to the external vehicle cab, allowing operators to control the device from inside the cab, further enhancing the device's operational convenience and intelligence.

[0029] The top of the liquid storage tank 2 is equipped with a fog cannon gun 3 and an air inlet pipe 4. The air outlet of the air inlet pipe 4 is connected to the air inlet of the fog cannon gun 3. A high-pressure pump 5 is embedded in the lower side of the liquid storage tank 2. The liquid inlet of the high-pressure pump 5 is connected to the inner cavity of the liquid storage tank 2. The liquid outlet of the high-pressure pump 5 extends through a pipe to the inner cavity of the fog cannon gun 3 and is connected to the built-in atomizing nozzle 6 arranged in a ring. A fan 7 is installed on the inner wall of the air inlet pipe 4. The air outlet of the fan 7 faces the fog cannon gun 3. A dust filter 8 is installed on the inner wall of the air inlet pipe 4 on the air inlet side of the fan 7.

[0030] When the dust suppression device used for atmospheric environmental management is in use, the high-pressure pump 5 transports the water inside the storage tank 2 to the atomizing nozzle 6 to form water mist. Then, the fan 7 drives the airflow to spray the water mist to the outside, and the water mist achieves the effect of dust suppression. During this process, the dust filter 8 is used to filter the air entering the air inlet duct 4.

[0031] A liquid level sensor 21 is fixedly installed on the inner wall of the liquid storage tank 2. The liquid level sensor 21 is an ultrasonic liquid level meter. The liquid level sensor 21 is connected to the cab of the external vehicle through the control panel 20. A replenishing valve 22 and a drain valve 23 are respectively embedded on the top and bottom sides of the liquid storage tank 2.

[0032] By setting up a liquid level sensor 21, the liquid level in the storage tank 2 can be monitored in real time, and the liquid level information can be transmitted to the driver's cab of the external vehicle through the control panel 20, so that the operator can know the amount of water in the storage tank 2 in a timely manner and avoid the dust suppression effect being affected due to insufficient water. At the same time, the setting of the replenishment valve 22 and the drain valve 23 facilitates the replenishment and draining of the storage tank 2, ensuring the continuous and stable operation of the device.

[0033] The air inlet end of the air inlet pipe 4 is equipped with a metal protective mesh 24.

[0034] By installing a metal protective mesh 24 at the air inlet end of the air inlet pipe 4, large particles of debris can be effectively prevented from entering the air inlet pipe 4 and damaging the fan 7 and dust filter 8, thereby extending the service life of the device and improving its reliability and stability.

[0035] A cleaning component is installed between the air inlet duct 4 and the dust filter 8.

[0036] The cleaning assembly includes a shaft 9 rotatably mounted on the inner wall of the air inlet duct 4. The shaft 9 is located on the side of the dust filter 8 near the fan 7. The central axes of the shaft 9 and the air inlet duct 4 are parallel. Several air-receiving blades 10 are fixedly mounted in a circular array at the end of the shaft 9 near the fan 7. A stop rod 11 is fixedly mounted at the end of the shaft 9 near the dust filter 8. Two guide slide rods 12 are symmetrically fixedly mounted on the inner wall of the air inlet duct 4. The dust filter 8 is slidably mounted on the surface of the guide slide rods 12. A cylinder 13 is fixedly mounted on the surface of the dust filter 8. The central axis of the cylinder 13 coincides with that of the shaft 9. A wave groove 14 is opened at the end of the cylinder 13 near the shaft 9. The position of the stop rod 11 corresponds to that of the wave groove 14. The surfaces of the stop rod 11 and the cylinder 13 are both treated with wear-resistant materials. The rotation of the shaft 9 causes the stop rod 11 to slide on the surface of the wave groove 14.

[0037] The upper end of the dust filter 8 is inclined towards the air inlet of the air inlet pipe 4. A dust discharge port is opened on the bottom side of the air inlet pipe 4 corresponding to the dust filter 8. A dust collection box 15 is fixedly installed on the bottom side of the air inlet pipe 4 corresponding to the dust discharge port. It is worth noting that by setting up a cleaning component, the wind force generated by the fan 7 drives the wind-receiving blades 10 to rotate, which in turn drives the shaft 9 to rotate. The abutment 11 on the shaft 9 slides on the surface of the corrugated groove 14 of the cylinder 13, pushing the dust filter 8 to move back and forth along the guide slide 12 to generate a vibration effect. This causes the dust attached to the surface of the dust filter 8 to fall downwards and enter the dust collection box 15 during the vibration process, thereby maintaining the permeability of the dust filter 8. This design does not require an additional power source such as a servo motor. It can achieve automatic cleaning of the dust filter 8 by using the wind force of the device itself during operation. This effectively avoids the wear problem between the cleaning brush and the dust filter 8 in the traditional cleaning method, extends the service life of the dust filter 8, ensures the dust filtration effect, and reduces the operating cost of the device.

[0038] A return spring 17 is fitted on the surface of the guide slide rod 12. The left and right ends of the return spring 17 are pressed against the inner wall of the air inlet pipe 4 and the surface of the dust filter 8, respectively. The return spring 17 drives the dust filter 8 to move to the right, so that the abutment rod 11 quickly returns to its original position and presses against the wave groove 14 at the end of the cylinder 13.

[0039] Furthermore, the reset spring 17 ensures that the dust filter 8 can be quickly reset, keeping the push rod 11 and the wave groove 14 in a tight abutment state, thus ensuring the continuous and effective operation of the cleaning component.

[0040] The bottom of the dust collection box 15 is provided with a cleaning port, and a cleaning plate 16 is detachably installed on the surface of the dust collection box 15 corresponding to the cleaning port by bolts.

[0041] It is worth noting that after the device is used, the dust inside the dust collection box 15 can be easily cleaned by opening the cleaning plate 16.

[0042] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
