Description

Technical Field

[0001] The invention relates to the technical field of dust suppression devices, in particular to an air quality feedback dust suppression device used in building safety engineering. Background Art

[0002] A large amount of dust and exhaust gas will be generated during the construction process. If these pollutants are directly discharged into the air, they will cause serious pollution to the surrounding environment and affect the air quality and ecological environment. The use of dust removal or dust reduction equipment can effectively collect and treat these dust and exhaust gases and reduce pollution to the environment.

[0003] In existing construction sites, atomization cannons are often used to achieve dust reduction effects. This treatment method will make local areas wet and muddy, and the open dust reduction method will have an adverse effect on the normal work on site. The closed dust removal method mainly attracts dust through dust collecting plates. The dust removal method is single, and dust can easily clog the filter screen, which cannot meet the needs of construction sites with larger dust. Summary of the invention

[0006] The fixing plate is mounted on the shell, the fixing plate is provided with a plurality of air inlets, a plurality of the air inlets are close to the outer side of the vortex sheet, the vortex sheet and the cleaning plate are fitted with each other, a sponge is provided on the cleaning plate in contact with the vortex sheet, the cleaning plate is made of magnetic shielding material, a plurality of air outlets are provided on the cleaning plate, a plurality of the air outlets are close to the middle of the vortex sheet, a dust removal chamber is formed between the vortex sheet and the cleaning plate, and the air inlet and the air outlet are both connected to the dust removal chamber; A negative electrode plate and a positive electrode plate are arranged on the inner wall of the vortex sheet, and the negative electrode plate and the positive electrode plate are respectively close to the air inlet and the air outlet, and the negative electrode plate and the positive electrode plate are respectively connected to the negative electrode and the positive electrode of the power supply through wires, and the vortex sheet, the negative electrode plate, the positive electrode plate and the cleaning plate are all distributed in a vortex line.

[0007] A cylinder is arranged in the middle of the lower side of the fixed plate, the cylinder is made of insulating material, an inner ring electrode is arranged on the outer side of the cylinder, a cylinder is arranged on the fixed plate outside the vortex sheet, an outer ring electrode and a coil are arranged on the inner and outer sides of the cylinder respectively, the inner ring electrode and the outer ring electrode are arranged oppositely and are located within the magnetic field range of the coil, and a plurality of spoilers are arranged at the bottom of the cylinder; The inner circle electrode and the outer circle electrode are respectively connected to the positive electrode and the negative electrode of the power supply through wires, the coil is electrically connected to the control system, and the two ends of the cylinder are respectively connected to the filling system through pipes passing through the shell. The filling system is installed on the shell and is used to transport cleaning fluid and air into the cylinder. The cleaning fluid is a conductive liquid.

[0008] When the vortex blade needs to be cleaned, the control system continuously energizes and deenergizes the first spring. After the first spring is energized, each turn generates a mutually attractive magnetic field, which shortens the first spring as a whole. The first spring pulls the cleaning plate to move upward, and the sponge on the cleaning plate moves upward to scrub the inner wall of the vortex blade, and the lower side of the vortex blade can be in contact with the cleaning liquid. After that, the staff transports the cleaning liquid into the cylinder through the filling system and the pipeline, and connects the coil to the circuit and the inner and outer electrodes to the positive and negative electrodes of the power supply respectively. The cleaning liquid contacts the inner and outer electrodes, and current flows through the cleaning liquid. The current in the cleaning liquid is affected by the magnetic field of the coil. Under the action of the Lorentz force, the cleaning liquid flows along the guide groove of the spoiler after flowing in a circle in the cylinder. The cleaning liquid moves toward the sponge along the guide groove (upward), and the cleaning liquid soaks the sponge while impacting the lower side of the vortex blade. The lower side of the vortex blade is rinsed by the liquid impact of the cleaning liquid, thereby improving the cleaning effect. The coil, the inner ring electrode and the outer ring electrode work for a set time and then are powered off. The filling system and the pipeline cooperate to transport air into the cylinder. The air drives the used cleaning fluid to be discharged from the pipeline on the other side to the filling system. The filling system processes the cleaning fluid and reuses it. When the filling system detects that the cleaning fluid is completely discharged, the control system controls the filling system to stop working and powers off the first spring. After the first spring is powered off, it gradually becomes longer under the action of its own elastic force. The first spring pushes the cleaning plate to move downward. The first spring is continuously powered on and off, so that the cleaning plate is continuously scrubbed up and down to clean the inner wall of the vortex blade.

A plurality of ash discharge outlets are provided on the circular plate near the filter screen, and a discharge plate is provided on the shell near the ash discharge outlet. The discharge plate and the shell are connected by a snap-on connection.

[0011] When the pressure cylinder moves upward with the follower plate, the chamber between the pressure cylinder and the fixed column becomes larger, and the external air pushes the one-way valve open and enters the chamber. After that, the pressure cylinder moves downward with the follower plate, and the chamber between the pressure cylinder and the fixed column becomes smaller. The air in the chamber is compressed and then ejected from the air jet port onto the filter screen. The pressurized air pushes the dust on the filter screen toward the dust discharge port. When the filter needs to be cleaned, the staff removes the discharge plate and opens the solenoid valve in the ash discharge port through the control system, so that the pressurized air pushes the dust out of the ash discharge port to the outside of the device, thereby cleaning the filter.

[0012] The two groups of baffles are installed on the shell, and a telescopic cylinder is connected between the follower plate and the upper baffle. The telescopic cylinder is located outside the active plate and is a telescopic structure. The telescopic cylinder is telescopic as the follower plate moves. A filter chamber is formed between the outside of the telescopic cylinder, the lower side of the filter screen and the annular plate, and the air inlet is connected to the filter chamber through a delivery pipe.

The rotating plate is located in the pressure hood and installed on the transmission shaft. A plurality of sliding grooves are provided in the rotating plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The positive plate and the negative plate cooperate to improve the dust removal effect of the vortex sheet. The negative plate discharges to the dust and air in the dust removal chamber and forms a corona, which ionizes the air into equal amounts of positive and negative ions. The positive ions are absorbed by the negative plate, and the negative ions are retained in the air. The dust is negatively charged after contacting the negative ions. The negatively charged dust continues to flow toward the air outlet and contact the positive plate. The positive plate attracts the negatively charged dust, causing the dust to deposit on the positive plate, thereby separating the dust and the air. Since the vortex sheet is distributed in a spiral line, the flow direction of the dust and air constantly changes when they flow in the dust removal chamber. The dust and air have different inertial forces. The dust hits the inner wall of the vortex sheet and loses kinetic energy. The air continues to flow toward the air outlet, further helping to separate the dust and the air, thereby improving the dust removal effect of the vortex sheet.

[0018] 2. Spray water outward through the spray pipe to quickly achieve large-area dust reduction. The control system closes the solenoid valves in the connecting pipe and the exhaust pipe and opens the solenoid valves in the liquid inlet pipe and the liquid outlet pipe, and drives the push plate to rotate through the drive motor. The push plate and the pressure cover cooperate to suck water through the liquid inlet pipe. After being pressurized, the water is sprayed outward through the liquid outlet pipe and the spray pipe to achieve large-area dust reduction treatment. No external equipment is required, and the structure is more compact.

[0019] 3. The filter screen is subjected to jet dust removal and vibration dust removal treatment to prevent dust from clogging the filter screen. The protrusions on the active plate first contact the protrusions on the follower plate, and the follower plate pulls the inner side of the filter screen upwards, making the filter screen as a whole conical. After that, the protrusions on the active plate and the protrusions on the follower plate are no longer in contact, and the follower plate drives the filter screen to gradually return to a horizontal state; through the continuous rotation of the active plate, the follower plate drives the filter screen to continuously vibrate, preventing dust from clogging the filter screen and ensuring the normal filtering effect of the filter screen; the pressurized air pushes the dust on the filter screen to move toward the dust discharge port to prevent dust from accumulating on the filter screen and ensure the filtering effect of the filter screen.

[0030] Working principle: Press the start button on the control panel 1, the dust suppression device starts, the control system opens the solenoid valves in the conveying pipe 305, the connecting pipe 303, and the exhaust pipe 304, and closes the solenoid valves in the liquid inlet pipe 301 and the liquid outlet pipe 302, and drives the transmission shaft 21 to rotate through the driving motor 2, and the transmission shaft 21 drives the active plate 24 and the rotating plate 31 to rotate, and the encoder in the driving motor 2 feeds back the rotation data of the active plate 24 and the rotating plate 31 to the control system; When the transmission shaft 21 drives the rotating plate 31 to rotate, the rotating plate 31 drives the pushing plates 32 on both sides to rotate, and the outermost ends of the pushing plates 32 are abutted against the pressure cover 3 by the reset tension spring, and the pushing plates 32 on both sides and the rotating plate 31 divide the pressure cover 3 into two independent chambers (the two independent chambers are the air inlet chamber and the air outlet chamber, respectively), and the air inlet chamber near the air inlet 291 gradually becomes larger, and the external air enters the air inlet chamber through the air intake port 111, the filter chamber, the delivery pipe 305, the air inlet 291, the dust removal chamber, the air outlet 292 and the connecting pipe 303 in turn, and the air outlet chamber near the air outlet 292 gradually becomes smaller, and the air in the air outlet chamber is discharged out of the device through the exhaust pipe 304, the exhaust hood and the exhaust port 112. Through the continuous rotation of the pushing plate 32, the dust-containing air is continuously sucked into the device and discharged after dust removal.

[0031] When the external dust-containing air enters the filter screen 23 through the air inlet 111, the transmission shaft 21 drives the active plate 24 to rotate, and the protrusion on the active plate 24 first contacts the protrusion on the follower plate 28, and the protrusion on the active plate 24 pushes the follower plate 28 to move upward, and the follower plate 28 drives the lifting plate 22 to move upward and compress the second spring, and the follower plate 28 pulls the inner side of the filter screen 23 upward, so that the filter screen 23 is conical as a whole, and then the protrusion on the active plate 24 and the protrusion on the follower plate 28 are not in contact, and the second spring is released and pushes the lifting plate 22 to The lifting plate 22 drives the following plate 28 to move downward, and the following plate 28 drives the filter 23 to gradually restore the horizontal state; the following plate 28 drives the filter 23 to vibrate continuously through the continuous rotation of the active plate 24, so as to prevent the dust from blocking the filter 23 and ensure the normal filtering effect of the filter 23; the larger particles of dust are deposited on the filter 23, and the smaller particles of dust and air pass through the filter 23 and enter the filter chamber, and the smaller particles of dust and air enter the dust removal chamber of the vortex sheet 252 through the conveying pipe 305 and the air inlet 291; When the flow meter in the conveying pipe 305 detects the flow of dust and air, the control system connects the negative plate 253 and the positive plate 254 to the negative and positive poles of the power supply respectively. The negative plate 253 discharges to the dust and air in the dust removal chamber and forms a corona, which ionizes the air into equal amounts of positive and negative ions. The positive ions are absorbed by the negative plate 253, and the negative ions are retained in the air. The dust is negatively charged after contacting the negative ions. After that, the negatively charged dust continues to flow toward the air outlet 292 and contacts the positive plate 254. The positive plate 254 attracts the negatively charged dust, causing the dust to settle. It accumulates on the positive plate 254 to separate the dust and air. Since the vortex sheet 252 is distributed in a spiral line, the flow direction of dust and air keeps changing when they flow in the dust removal chamber. However, the dust and air have different inertia forces. The dust hits the inner wall of the vortex sheet 252 and loses kinetic energy.
