Further, as a filter device including a device for removing dust adhering to the filter, for example, the one described in Patent Document 1 is known. This filter device removes dust adhering to the rotating disk-shaped filter with a rotating brush.

Japanese Unexamined Patent Publication No. 2011-50962

By the way, the conventional filter device has a problem that dust adheres to the filter, which clogs the filter and weakens the ability to collect the dust.

Further, the method of removing the dust adhering to the filter with a brush as described in Patent Document 1 has a problem that only the dust on the surface of the filter can be removed and the dust stuck in the eyes of the filter cannot be removed well. There is a problem that dust is pushed out from the back side of the filter by the brush and diffused. Further, since the brush comes into contact with the filter, there is a problem that the filter is easily damaged.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a filter device capable of maintaining filter performance for a long period of time.

In order to achieve the above object, the filter device of the present invention is a filter device including a filter, a turbine rotated by a fluid flow, and a power transmission unit.
The filter is characterized in that it is provided in a state in which it can be circulated by the power generated by the rotation of the turbine transmitted through the power transmission unit.

In the present invention, the filter is provided in a state in which it can orbit. In addition, the turbine rotates due to the flow of fluid. Further, the power generated by the rotation of the turbine is transmitted to the filter via the power transmission unit.
Therefore, the turbine rotates due to wind, water flow, etc., and the power generated by this rotation is transmitted to the filter, and the filter goes around.

The surface that mainly functions as a filter is the surface that faces the side where the fluid flows, but by orbiting the filter, the surface that functions as the filter can be orbited and directed toward the side where the fluid flows. it can. Therefore, the effective area of the filter can be widened, and the filter device can be used for a long period of time without causing clogging of the filter without replacing the filter. Therefore, the filter performance can be maintained for a long period of time.
Further, since the filter can be rotated by a natural force such as wind or water flow, it is not necessary to provide a motor or the like for rotating the filter.

Further, in the configuration of the present invention, it is preferable to provide an ejection device for ejecting air toward the filter.

According to such a configuration, air is ejected from the ejection device toward the filter. Therefore, the dust adhering to the filter can be removed by the ejected air. Further, since the filter orbits due to the rotation of the turbine, dust of the entire filter can be removed even if the ejection device is provided so that the air ejected from the ejection device hits a part of the filter.

Further, since the dust is removed by the ejected air, the dust can be pushed out in a predetermined direction by the air, and the dust can be collected in one place. Moreover, since the brush or the like does not come into contact with the filter, the filter is not easily damaged.

According to the filter device of the present invention, the filter performance can be maintained for a long period of time.

Further, the rotation of the impeller 317 of the rotating device 310 causes air to flow from the air intake section 21 toward the air discharge section 25. Then, air is taken into the air intake unit 21 from the outside of the dust collector 3.
Further, the dust collector 3 is provided with an introduction portion 30 so as to surround the front side wall member 20 of the structure 10 in which the air intake portion 21 is provided. Since the portion of the introduction portion 30 opposite to the air intake portion 21 is widely opened, the air coming toward the introduction portion 30 is guided to the air intake portion 21. Therefore, a wider range of air can be taken into the dust collector 3 as compared with the case where the introduction unit 30 is not provided.
In particular, when dust is collected by the dust collecting vehicle 1 while the dust collecting vehicle 1 is running, the effect of the introduction unit 30 is great. That is, while the dust collecting vehicle 1 is traveling, the air flow from the air intake unit 21 to the air discharging unit 25 is also generated by the traveling of the dust collecting vehicle 1, but the introduction unit 30 causes a wider range of air. Can be guided to the air intake unit 21, so that more air and dust can be taken into the dust collector 3.

The air taken into the dust collector 3 from the air intake unit 21 first passes through the first filter main body 51 of the first filter device 50, and a part of the dust contained in the air is captured by the first filter main body 51. Be gathered.
The air that has passed through the first filter body 51 then passes through the tubular member 102 of the second filter device 100. Since the coil 101 is wound around the tubular member 102 and a current is passed through the coil 101, the air that has passed through the tubular member 102 is ionized and purified.
The air that has passed through the tubular member 102 is then applied to the laser beam L of the third filter device 150. Since the laser light L has a bactericidal power, bacteria contained in the air passing through the laser light L are killed. Further, by using the laser light L, higher sterilizing power can be obtained as compared with the case of using the ultraviolet light, so that the air passing through the laser light L can also be sterilized.
The air applied to the laser beam L then passes through the activated carbon filter 201 of the fourth filter device 200. Then, carbon monoxide, carbon dioxide, exhaust gas and the like contained in the air are adsorbed on the activated carbon filter 201. In addition, the activated carbon filter 201 also deodorizes, for example, the odor of ammonia.
The air that has passed through the activated carbon filter 201 then passes through the HEPA filter 251 of the fifth filter device 250. Then, the bacteria killed by the laser beam L and other dust remaining in the air are collected by the HEPA filter 251.
The air that has passed through the HEPA filter 251 then passes through the cooling bed 301. Since the cooling bed 301 is moistened with water, the air passing through the cooling bed 301 is cooled.
As described above, the cleaned and cooled air is discharged from the air discharge unit 25.

The arrangement of each filter device and the rotating device 310 is not limited to the order of the present embodiment. It suffices that the rotating device 310 causes air to flow from the air intake section 21 toward the air discharge section 25, and this air passes through each filter device.
Further, each filter device and the cooling bed 301 may be provided with only necessary ones according to the dust to be collected and the necessity of cooling the air. At this time, since the structure 10 in which each filter device or the like is provided has a frame assembled by the structural material joint 11 and the structural material 17, it is easy depending on the number and size of the devices or the like to be provided inside. In addition, the structure 10 can be enlarged or reduced.
Further, the first filter main body 51 and the HEPA filter 251 may use different types of air filters or the like depending on the type of dust to be collected.

Such a dust collecting vehicle 1 is, for example, a place where an event such as a festival is held, a place where people such as a school gather, a place where the traffic of cars is heavy, or a place where the air is easily polluted or dirty. It is used by stopping at. The dust collecting vehicle 1 is provided with a vehicle body 2 which is a truck capable of loading a 20-foot container and can run by the power of a prime mover. Therefore, the dust collecting vehicle is located in such a place only when people gather. It is possible to move 1 to remove dust in the air and cool the air.
Since the dust collector 3 can be handled in the same manner as a normal container and can be easily removed, the dust collector 3 can be removed and installed to purify the air.

Further, the dust collecting vehicle 1 can also be used while traveling. For example, it is possible to purify the air in such an area by traveling in an area where air pollution is severe.
Further, since the blower device 4 is provided in the lower part of the driver's seat 2a of the vehicle body 2 in a state where the blower port 4a is directed downward and rearward, the blower device 4 is operated. The wind is blown from the blower 4 toward the ground, and the dust on the ground is blown toward the plate-shaped portion 31d and the air intake portion 21. Therefore, by running the dust collecting vehicle 1 while moving the blower 4, the blown (flyed up) dust can be sucked into the dust collecting device 3 and collected. Therefore, it is possible to collect dust that has fallen on the ground like a road cleaning vehicle. In a conventional road surface cleaning vehicle that directly sucks dust on the ground like a vacuum cleaner, the suction force is narrow and the suction force is weak, so the road surface cleaning vehicle must run slowly and it takes time to clean. .. In addition, in the case of a road cleaning vehicle that uses a brush to collect dust on the ground, it is necessary to replace the brush regularly, which increases running costs. On the other hand, in the dust collecting vehicle 1 according to the present embodiment, the blower 4 can blow dust and the like on the ground toward the plate-shaped portion 31d and the air intake portion 21 and collect the dust and the like. Even if the dust collecting vehicle 1 is run at high speed, dust and the like can be collected, and there is no cost of replacing the brush.
Further, by increasing the strength of the wind sent from the blower device 4, relatively large dust and the like can be collected. Therefore, for example, the dust collecting vehicle 1 can be used to collect fragments and pebbles of airplane tires that have fallen on the runway of an airplane, and to maintain an athletic field. Further, the first filter main body 51 or the like of the first filter device 50 may be changed so as to be a filter suitable for collecting the dust or the like according to the size of the dust or the like to be collected.

In the first filter device 50 according to the present embodiment, the turbine 52 is rotated by the air flowing from the front to the rear of the first filter device 50. Further, the rotation of the turbine 52 is transmitted to the roller 53c via the belt (power transmission unit) 54, and the roller 53c rotates. Then, as the roller 53c rotates, the first filter main body 51 stretched between the three rollers 53 goes around.

Therefore, the surface of the first filter main body 51 facing the air flow side (air intake portion 21 side) is sequentially changed. That is, in the first filter main body 51, the surface that mainly functions as a filter is the surface facing the side through which the fluid flows. The surface that functions as a filter can be moved around and turned. Therefore, the effective area of the filter can be widened, and the filter is less likely to be clogged without replacing the filter. Therefore, the filter performance of the first filter main body 51 can be maintained for a long period of time. In addition, since the force for collecting dust of the filter does not easily decrease, the air can be efficiently purified.

Further, since the first filter main body 51 can be rotated by a natural force such as wind or water flow, it is not necessary to provide a motor or the like for rotating the first filter main body 51.
Further, by using the rotating device 310 of the dust collecting vehicle 1 according to the present embodiment in combination with a device for flowing air, the flowed air can circulate the first filter main body 51. Then, for example, the circumferential speed of the first filter main body 51 can be adjusted by adjusting the rotation speed of the rotation shaft 312 of the rotation device 310.

Further, the ejection device 80 is arranged inside the first filter main body 51, and the ejection ports 82a of the plurality of ejection portions 82 are directed downward, that is, toward the first filter main body 51 side. Then, the air compressed by the rotating device 310 is ejected from the ejection port 82a. Further, a dust collecting unit 58 and a dust storage unit are provided on the lower side of the first filter device 50.
Therefore, the air ejected from the ejection port 82a pushes out the dust adhering to the first filter main body 51, and the dust is collected in the dust storage unit through the dust collecting unit 58. Further, a plurality of ejection portions 82 are provided in the axial direction of the pipe 81 extending in the left-right direction, and the first filter main body 51 orbits around the pipe 81 due to the rotation of the turbine 52.
Dust from the entire filter can be removed and stored in the dust storage section.
Therefore, the first filter main body 51 is not clogged, and the filter performance can be maintained for a long period of time. Further, since the dust is pushed out by the air, the filter is less likely to be damaged and the filter performance can be maintained for a long period of time as compared with the method of removing the dust by rubbing the filter with a brush or the like.

Further, in the second filter device 100 according to the present embodiment, the rear surface plate 104 is provided with a plurality of holes 105 aligned in the vertical direction and the horizontal direction, and the front plate 103 is also provided with the holes 105 of the rear surface plate 104. A hole is provided at a position facing the above. Further, one end of the tubular member 102 is fitted into the hole 105 of the rear surface plate 104, and the other end is fitted into the hole of the front plate 103 at a position facing the hole 105. .. Therefore, the tubular members 102 are arranged so as to be aligned in the vertical direction and the horizontal direction with the axis oriented in the front-rear direction.
A coil 101 is wound around the outer peripheral portion of each tubular member 102 between the front plate 103 and the rear plate 104, and a current is passed through the coil 101 from the rotating device 310. Then, the air that has passed through the first filter device 50 passes through the inside of the tubular member 102 of the second filter device 100.
A magnetic field is generated inside the tubular member 102 by passing an electric current through the coil 101, and each molecule or the like in the air passing through the inside of the tubular member 102 is affected by this magnetic field. Then, the molecules exposed to the magnetic field are easily ionized. In addition, charged particles in the air receive a force from a magnetic field and an electric field, become active in motion, and collide with molecules in the air or the inner wall of a tubular member to generate negative ions. Therefore, negative ions increase and the air is purified.
In addition, harmful substances are decomposed and the air is purified by the collision of charged particles with active movement.
Further, since the tubular member 102 is made of copper and is heated by the current flowing through the coil 101, bacteria in contact with the tubular member 102 can be killed. Therefore, the air passing through the inside of the tubular member 102 is purified. The tubular member 102 is not limited to copper, but can be heated and kill bacteria even if it is made of other metal or the like.

Further, the coil 101 includes a counterclockwise portion 101a in which the coil 101 is wound counterclockwise when viewed from the front side in the axial direction, and a clockwise portion 101b in which the coil 101 is wound clockwise. Further, the counterclockwise portion 101a and the clockwise portion 101b are alternately and repeatedly arranged along the axial direction of the tubular member 102. Therefore, the charged particles and the like passing through the inside of the tubular member 102 receive a force from a magnetic field whose direction changes alternately. Therefore, as compared with the case where the coil 101 is simply wound in one direction, the movement of the charged particles and the like becomes more random and active, the molecules are more likely to react, and negative ions are also more likely to be generated. Therefore, the air passing through the inside of the tubular member 102 is more purified.

Further, in the third filter device 150 according to the present embodiment, the laser device 151 is fitted into the holes 154 and 156 arranged in the left-right direction so that the laser beam L is radiated in the downward direction. It is provided in a state of being. Further, the plurality of holes 154 and holes 156 arranged on the front side are arranged at the same pitch P in the left-right direction, and the plurality of holes 154 and holes 156 arranged on the rear side are arranged at the same pitch P in the left-right direction. Although arranged, the holes 154 or 156 arranged on the rear side are located at the center position between the holes 154, 154 or 156, 156 which are arranged on the front side and are adjacent to each other on the left and right sides. That is, the holes 154 and 156 are provided side by side in the left-right direction, and the adjacent holes 154 and the adjacent holes 156 are arranged at positions shifted in the front-rear direction.
Therefore, it is possible to prevent the adjacent laser devices 151 from colliding with each other in the left-right direction, and to arrange the laser devices 151 with a close interval in the left-right direction. In particular, when the laser device 151 has a portion protruding in the left-right direction, the effect is great because the adjacent holes 154 and the adjacent holes 156 are displaced in the front-rear direction. Further, the hole 154 (hole 156) arranged on the front side and the hole 154 (hole 156) arranged on the rear side adjacent to the hole 154 (hole 156) are partially overlapped in the left-right direction. It can also be placed in.

Further, the air passing through the second filter device 100 will pass through the tubular member 102. Therefore, when the air that has passed through the second filter device 100 is sterilized by the third filter device, the laser device 151 can be arranged so that the laser light L passes on the rear extension line of each tubular member 102. desirable.
In the third filter device 150 according to the present embodiment, the laser devices 151 are arranged so as to be closely spaced in the left-right direction so that the tubular members 102 arranged at predetermined intervals in the left-right direction are extended on the rear side. The laser device 151 is arranged so that the laser beam L passes through. Further, the laser light L emitted from one of the laser devices 151 passes on the rear extension line of the tubular members 102 arranged at predetermined intervals in the vertical direction.
Further, one laser device 151 is provided for each vertical row of the arranged tubular members 102, and the laser light L emitted from one laser device 151 is a single row aligned in the vertical direction. Tubular member 102 passes on all axial rear extension lines. Therefore, the air flowing out of the tubular member 102 is exposed to the bactericidal laser light emitted from the laser device 151.
Therefore, the bacteria contained in the air that has passed through the second filter device 100 can be exposed to a laser beam having a large amount of heat and high bactericidal power to kill the bacteria, and the air can be purified.
Further, the number of laser devices 151 required is such that the laser light L emitted from one laser device 151 passes on the axial rear extension lines of all the tubular members 102 in a row aligned in the vertical direction. Has been reduced.

Further, in the rotating device 310 according to the present embodiment, the rotating shaft 312 is rotated by the rotation of the prime mover 313. Then, by rotating the rotating shaft 312, power generation is performed by the cooperation of the permanent magnet 315 and the coil 318, ventilation is performed by the rotation of the impeller 317, and air is compressed by the rotation of the impeller 316.
Therefore, one power source can be used for ventilation, power generation and gas compression.
Further, the permanent magnet 315, the impeller 316 and the impeller 317 are provided on one rotating shaft 312. That is, the permanent magnet 315, the impeller 316, and the impeller 317 are arranged coaxially.
Therefore, the size of the rotating device 310 in the radial direction of the rotating shaft 312 can be reduced, and the rotating device 310 can be miniaturized, so that the rotating device 310 can be installed in a space-saving manner.

Further, when the adjustment knob 331 is turned in the direction in which the wire 329 is loosened, the connecting member 328 moves via the adjustment mechanism inside the second support member 327, and the blade 325 moves in a direction parallel to the rotation direction of the impeller 317 (in the direction parallel to the rotation direction of the impeller 317. It is designed to rotate so as to face (the direction perpendicular to the rotation axis 312). Further, when the adjustment knob 331 is turned in the direction in which the wire 329 is pulled, the connecting member 328 moves via the adjustment mechanism inside the second support member 327, and the blade 325 is in the direction perpendicular to the rotation direction of the impeller 317 (the direction perpendicular to the rotation direction of the impeller 317. It is designed to rotate so as to face (direction parallel to the rotation axis 312).
Therefore, the angle of the blades of the impeller can be changed, and the pressure applied to the air by the impeller and the air volume sent by the rotation of the impeller can be adjusted as necessary.

Further, in the dust collecting vehicle 1 according to the present embodiment, when the introduction portion 30 is in the most closed state, the area of the opening on the opposite side of the structure 10 is set before the air intake portion 21 is provided. The area is widened by the amount that the plate-shaped portion 31d below the area of the side wall member 20 is open. In the open state, the area is opposite to that of the structure 10 from this most closed state. The opening is designed to open. Therefore, in the open state, the introduction portion 30 has a larger area of the opening on the opposite side than the area of the opening on the air intake portion 21 side, so that the wind coming toward the introduction portion 30 is collected and the air intake portion 30 is collected. Can lead to 21. Therefore, since the introduction unit 30 can guide a wide range of air to the inside of the dust collector 3 and purify it, the air can be efficiently purified.
Further, the plate-shaped portion 31 which is a part of the introduction portion 30 is connected to the structure 10 via a telescopic cylinder 36, and the plate-shaped portion 31 is moved up and down or left and right by the expansion and contraction of the cylinder 36. Swing. Then, the introduction portion 30 opens and closes as the plate-shaped portion 31 swings. Therefore, the introduction unit 30 is in a state where it can be opened and closed, and by closing the introduction unit 30, it is possible to easily travel even in a narrow place.

Further, the introduction portion 30 is provided on the front surface side of the structure 10 in which the air intake portion 21 is provided, and in the closed state, the upper plate-shaped portion 31a protrudes forward from the structure 10. , It is substantially parallel to the upper surface of the structure 10, and the left and right plate-shaped portions 31b and 31c are substantially parallel to the left and right surfaces of the structure 10 in a state of protruding forward from the structure 10. Then, from this state, the front of the upper plate-shaped portion 31a opens upward, and the left and right plate-shaped portions 31b and 31c open in the left-right direction, respectively, so that the introduction portion 30 is opened. That is, in the introduction portion 30, the opening on the opposite side of the air intake portion 21 is directed forward in the traveling direction of the dust collecting vehicle 1 in the open state. Therefore, when the dust collecting vehicle 1 travels, air flows from the introduction unit 30 to the air intake unit 21 and the air discharging unit 25. Therefore, by running the dust collecting vehicle 1, dust in the air can be generated. Can be collected, and the air in a wide range in which the dust collecting vehicle 1 is driven can be purified.
Therefore, the air can be purified efficiently.

Further, in the dust collecting vehicle 1 according to the present embodiment, the blower device 4 is provided below the driver's seat 2a with the blower port 4a facing downward and rearward. Dust contained in the air includes dust that repeatedly falls on the ground and scatters again, but it is efficient because the dust that has fallen on the ground can be lifted up and collected by the blower 4. Can collect dust and purify the air.

Further, among the plate-shaped portions 31 located on the top, bottom, left, and right of the dust collector 3, the plate-shaped portions 31 (31a, 31b, 31c) located on the upper, left, and right sides are provided with the sensor 33. Then, the information on the obstacle detected by the sensor 33 is sent to the control circuit provided in the dust collector 3, and this control circuit gives a command to expand and contract the cylinder 36 according to the information on the obstacle detected by the sensor 33. Is issued, and the cylinder 36 expands and contracts based on this command. Therefore, when there is an obstacle while the dust collecting vehicle 1 is traveling, the introduction unit 30 automatically opens and closes, so that the vehicle can travel smoothly and can travel a longer distance in a short time. , It is possible to purify a wide range of air, and it is possible to purify the air efficiently. Further, as the traveling speed increases, more air flows from the introduction unit 30 toward the air discharging unit 25, but since the sensor 33 detects an obstacle, the traveling speed can be increased even in a narrow place or the like. It can clean the air efficiently.
The sensor 33 may be provided in the driver's seat 2a or the structure 10, but since the sensor 33 is mainly for detecting an obstacle so that the introduction portion 30 does not hit the obstacle, the sensor 33 is introduced. It is preferable that the introduction portion 30 is provided so that the distance between the portion 30 and the obstacle can be accurately measured.
