Description

Technical Field

[0001] The invention relates to the technical field of collecting large-diameter floating objects, and in particular to a device for collecting large-diameter floating objects in ambient air. Background Art

[0002] Poplars grow fast, have a long lifespan, are drought and salinity resistant, and can be planted in a wide range. However, when poplar fruits mature, the poplar fluff produced after the fruits crack floats in the air. The poplar fluff in the air can cause environmental pollution and carry dust and bacteria, which can make people's respiratory tract obstructed and cause respiratory diseases. The large-diameter floating object collection device can collect large-diameter floating objects (such as poplar fluff) floating in the air, reduce environmental pollution, and ensure that people can breathe smoothly.

[0003] For example, the patent document with publication number CN111617579A discloses a device for collecting large-diameter floating objects in ambient air. After collecting large-diameter floating objects, the device not only blocks the filter screen, but also large floating objects such as catkins float in the inner cavity of the collection device. After the collection device is opened, large floating objects such as catkins float out. At the same time, in areas with flying sand and gravel, some large floating objects are mixed with sand and gravel, which is not convenient for later treatment. For this reason, we provide a device for collecting large-diameter floating objects in ambient air to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a device for collecting large-diameter floating objects in ambient air. The device has a simple structure and can not only automatically collect large-diameter floating objects in the air, but also separate and collect the large-diameter floating objects that enter, so that large-diameter floating objects that are easy to float, such as catkins, are mixed with water and collected, thereby avoiding clogging of the filter screen and preventing large-particle floating objects, such as catkins, from floating out.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts a large-diameter floating object collection device in ambient air, comprising:

[0006] A collecting device, wherein a separation chamber is provided inside the collecting device;

[0007] An air inlet is disposed on the top surface of the separation chamber and allows floating matter in the outside air to enter the separation chamber along the air inlet;

[0008] a water supply port, which is disposed on one side of the air intake port and allows water to enter the separation chamber along the air intake port;

[0009] an air supply device, the air supply device is placed at the bottom of the separation chamber and makes the water in the separation chamber present a first fluidized bed structure, after the floating objects enter the first fluidized bed structure, the floating objects with a density less than that of water rise and the floating objects with a density greater than that of water sink;

[0010] The collecting device is placed at the tail end of the flow direction of the first fluidized bed structure, and the collecting device is provided with a floating object collecting chamber and a sand and stone collecting chamber along the vertical direction.

[0011] The above structure can separate and collect large-diameter floating objects that enter the filter at the same time, and can also mix and collect large-diameter floating objects such as catkins that are easy to float with water, so as to avoid clogging the filter net and prevent large particles of floating objects such as catkins from floating out.

[0012] As a further optimization of the above scheme, an inclined orifice plate is provided inside the above separation chamber, and the inclined orifice plate is arranged toward the sand and gravel collecting chamber. The inclined orifice plate can make the water in the above separation chamber tilt from one side wall to the other side wall, thereby, the other side wall guides the sediment into the sand and gravel collecting chamber. Therefore, the first fluidized bed structure moves smoothly to avoid the accumulation of sand and gravel on the inclined orifice plate.

[0013] As a further optimization of the above solution, considering that the volume of floating objects is smaller than the volume of sand and gravel, the inlet of the floating object collecting chamber is smaller than the inlet of the sand and gravel collecting chamber.

[0014] As a further optimization of the above scheme, the above-mentioned sand and gravel collection chamber is connected to the water supply port through a water supply pipe, and the above-mentioned sand and gravel collection chamber and the water supply port are connected with a pump body to reuse the water discharged into the sand and gravel collection chamber to achieve the recycling of water resources.

[0015] As a further optimization of the above scheme, the above-mentioned floating object collection chamber is connected to the above-mentioned sand and gravel collection chamber by a connecting port, and a filter net is provided on the connecting port to facilitate the water entering the floating object collection chamber to be introduced into the sand and gravel collection chamber for use, thereby enhancing the utilization effect of water resources.

[0016] As a further optimization of the above scheme, an aeration element is provided below the above filter screen, and the aeration element is provided to aerate the filter screen regularly to reduce the clogging phenomenon of the filter screen.

[0017] As a further optimization of the above scheme, the number of the above-mentioned connecting ports is multiple, and the above-mentioned aeration member is a first fan to make the water in the above-mentioned floating object collecting chamber present a second fluidized bed structure, and the floating objects with a density less than that of water rise. Through the setting of the second fluidized bed structure, the floating objects in the above-mentioned floating object collecting chamber are all gathered at the top of the floating object collecting chamber, thereby preventing the floating objects from settling and clogging the filter screen.

[0018] As a further optimization of the above scheme, the above floating object collection chamber is connected to the water supply pipe, which is conducive to the formation of the above second fluidized bed structure while introducing water without floating objects into the water supply pipe for reuse at the water supply port.

[0019] As a further optimization of the above scheme, a second fan with a sealed end facing downward is also provided inside the above-mentioned connecting port, so that the sand and gravel collecting chamber presents a third fluidized bed structure, and floating objects with density greater than that of water descend. The above-mentioned second fan is arranged so that the sand and gravel in the above-mentioned sand and gravel collecting chamber are deposited to the bottom, and do not enter the water supply pipe along with the water in the sand and gravel collecting chamber, thereby optimizing the cleanliness of the recycled water.

[0020] As a further optimization of the above scheme, a guide block is provided between the inlet of the floating object collection chamber and the inlet of the sand and gravel collection chamber. The guide block is triangular in shape and its top surface is inclined toward the floating object collection chamber while its bottom surface is inclined toward the sand and gravel collection chamber. The setting of the guide block further optimizes the separation of floating objects and sand and gravel in the first fluidized bed structure.

[0021] The device for collecting large-diameter floating objects in ambient air of the present invention has the following beneficial effects:

[0022] 1) The present invention can effectively and stably classify and collect floating objects and sand and gravel without affecting the original collection device, so that large-diameter floating objects such as catkins that are easy to float are mixed with water and collected, so as to avoid the situation that the large-diameter floating objects flying in the inner cavity block the filter screen, and to avoid the situation that large-particle floating objects such as catkins float out. More importantly, the above separation method uses a fluidized bed structure. Specifically, gas is used to spray water to fluidize the water flow to form a fluidized bed, and the objects to be separated are introduced into the fluidized bed, wherein objects with a density lower than the apparent density of the fluidized bed are suspended, and objects with a density higher than the apparent density of the fluidized bed are settled, and the specific gravity separation method in the fluidized bed is used to separate the two objects, so as to efficiently realize the separation and collection of sand and gravel from large-diameter floating objects, and avoid the problem that sand and gravel are mixed with large-diameter floating objects and are difficult to handle later.

[0023] 2) The present invention realizes the recycling of water resources and avoids the waste of water resources by connecting the water supply port with the sand and gravel collection chamber. At the same time, by connecting the floating object collection chamber with the sand and gravel collection chamber, the recycling effect of water resources is further enhanced.

[0024] 3) Furthermore, in the present invention, the floating object collection chamber is designed as a second fluidized bed structure and the sand and gravel collection chamber is designed as a third fluidized bed structure, ensuring that the floating objects in the floating object collection chamber float on the top of the above-mentioned floating object collection chamber to prevent the floating objects from mixing into the water supply pipe, and the sand and gravel in the sand and gravel collection chamber are deposited at the bottom of the above-mentioned sand and gravel collection chamber to prevent the sand and gravel from mixing into the water supply pipe, thereby optimizing the cleanliness of the recycled water.

The terms used in the specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] In the following, reference will be made to Figure 1-Figure 3 A first embodiment of a device for collecting large-diameter floating objects in ambient air according to the present invention is described.

[0034] Here, an example of separating catkins and sand and stones according to the collecting device of the present invention will be described, but the collecting device is not limited thereto and can be applied to various separated objects.

[0035] Attached Figure 1 is a schematic diagram of a collecting device according to a first embodiment of the present invention.

[0036] The collecting device 1 of this embodiment has a box-shaped container for accommodating a first fluidized bed structure, namely, a separation chamber 11. The first fluidized bed structure is composed of a suitable liquid, preferably water in this embodiment. A water supply port 3 (water supply unit) is provided at the top of the separation chamber 11 to supply water appropriately for forming a fluidized bed in the separation chamber 11. A supply device for supplying (sucking) the separation object into the separation chamber 11 through an air inlet 2 (separation object) is provided above the separation chamber 11 and is located near the water supply port 3. Here, the separation object of this embodiment is composed of catkins and sand and gravel, the density of sand and gravel is large and the density of catkins is small, and the density of the sand and gravel is greater than that of water and the density of catkins is less than that of water.

[0037] The bottom surface of the separation chamber 11 as a box-type container is composed of an inclined orifice plate 7 having the property of allowing air to pass through but not allowing water to pass through. In particular, in this embodiment, the inclined orifice plate 7 is selected to be a breathable plate. The inclined orifice plate 7 is arranged to be inclined so as to become lower as it moves away from one end of the separation chamber 11, which is a water supply position serving as the water supply port 3, toward the other end.

[0038] Generally speaking, there is a wall effect near the boundary between the fluid and the wall, that is, the resistance of the fluid is suppressed from acting on the fluid. The wall effect affects a predetermined area from the wall, and the flow rate of the fluid in this area is significantly reduced. The same can be said for the wall effect in the above-mentioned separation chamber 11.

[0039] In this regard, in the separation chamber 11 according to the present embodiment, the moving range of the separation object is also limited by the above-mentioned inclined orifice plate 7. As a result, the separated object moves to the area where the moving speed of the fluid in the first fluid bed structure is insufficient, and the bottom and side (near) of the separation chamber 11, and therefore, the above-mentioned inclined orifice plate 7 can suppress the retention of the separation object caused by the avoidance effect, etc. In addition, these inclined orifice plates 7 have a simple structure, and therefore, have the function of suppressing the retention of the above-mentioned sediments, and can be easily added to the existing storage device 1. In addition, in the first fluidized bed structure, only the area where the moving speed of the water body is sufficient can be selected, thereby improving the separation efficiency.

[0040] Furthermore, in this embodiment, the inclined orifice plate 7 is designed as a thin plate structure to avoid obstructing the air flow from the wind box and not damaging the fluidization state of the first fluidized bed structure.

[0041] A plurality of wind boxes (air supply devices 4) separated by a plurality of partitions are provided below the inclined orifice plate 7 forming the bottom surface of the separation chamber 11, and air is supplied to the separation chamber 11. As a result, the water body is fluidized to form a first fluidized bed body. The above-mentioned apparent density is the mass per unit volume when the water body is fluidized. The supply amount of air supplied to the wind box is adjusted by an independent air supply mechanism (not shown).

[0042] In this embodiment, eight bellows are provided. Figure 1 As shown, but the number of bellows is not limited thereto. In addition, the top of the separation chamber 11 as a box-shaped container can be closed with a plate body, which can be designed to an easy-to-open hinged structure and can be appropriately selected according to the external environment.

[0043] Furthermore, suitable water is pre-stored in the separation chamber 11, and air is supplied from a bellows at a prescribed wind speed, the prescribed wind speed being, for example, about 120% of the minimum fluidization velocity, the minimum fluidization velocity being the state in which the water is, and being the lower limit of the required wind speed. As described above, a first fluidized bed structure supported by the water is formed in the separation chamber 11.

[0044] In addition, water is supplied from the water supply port 3 provided at the top of the separation chamber 11 at a constant flow rate, and on the other hand, the water is discharged from the collection device 1 provided at the other end of the separation chamber 11 .

[0045] An inlet of a sand and gravel collecting chamber 6 is provided at the bottom of the other end of the separation chamber 11 . In addition, the sand and gravel sediments and water flow settled in the first fluidized bed structure are discharged into the sand and gravel collecting chamber 6 provided below the separation chamber 11 .

[0046] As described above, water is supplied from the water supply port 3 arranged above one end of the separation chamber 11, and water and sediment are discharged from the inlet of the sand and gravel collection chamber 6 arranged at the bottom of the other end of the separation chamber 11, and the first fluid bed structure slowly moves from one end of the separation chamber 11 to the other end.

[0047] One side of the wall between the inlet of the floating object collecting chamber 5 and the inlet of the sand and gravel collecting chamber 6 is inclined toward the floating object collecting chamber 5 and the other side is inclined toward the sand and gravel collecting chamber 6 to form a triangular guide block 9. In this process, water mixed with floating objects flows into the floating object collecting chamber 5 and water mixed with sand and gravel flows into the sand and gravel collecting chamber 6, thereby optimizing the separation of floating objects and sand and gravel in the first fluidized bed structure.

[0048] In this embodiment, the inclination angle of the guide block 9 relative to the horizontal upper inclined portion is preferably about 5° to 45°, but is not limited and can be selected in an appropriate manner. The guide block 9 is discharged into the sand collection chamber 6 through an appropriate inclined surface or slope for the horizontal lower inclined portion.

[0049] In this embodiment, considering that the volume of floating objects is smaller than that of sand and gravel, the inlet of the floating object collecting chamber 5 is smaller than the inlet of the sand and gravel collecting chamber 6 .

[0050] To sum up, the present invention can effectively and stably classify and collect floating objects and sand and gravel without affecting the original collection equipment 1, so that large-diameter floating objects such as catkins that are easy to float are mixed with water and collected, so as to avoid the situation that the large-diameter floating objects flying in the inner cavity block the filter screen, and to avoid the situation that large-particle floating objects such as catkins float out. More importantly, the above-mentioned separation method uses a fluidized bed structure. Specifically, gas is used to spray water to fluidize the water flow to form a fluidized bed, and the objects to be separated are introduced into the fluidized bed, wherein objects with a density lower than the apparent density of the fluidized bed are suspended, and objects with a density higher than the apparent density of the fluidized bed are settled, and the specific gravity separation method in the fluidized bed is used to separate the two objects, so as to efficiently realize the separation and collection of sand and gravel from large-diameter floating objects, and avoid the problem that sand and gravel are mixed with large-diameter floating objects and are difficult to process later.

[0051] Figure 1 Schematic representations are for illustrative purposes only and are not limiting of the disclosed examples.

[0052] Furthermore, there are various types of collection devices, many of which may benefit from the examples disclosed herein and are not limited to the designs shown.

[0053] Next, based on Figure 2 and Figure 3 Considering the waste of water resources caused by the fluidized bed structure composed of water bodies, the present invention describes a second embodiment of a large-diameter floating object collection device in ambient air according to the present invention. In addition, the second embodiment has components with the same shape or function as the first embodiment. Here, only the differences between the second embodiment and the first embodiment will be described.

[0054] In this embodiment, the sand and gravel collection chamber 6 is connected to the water supply port 3 through a water supply pipe 61, and the sand and gravel collection chamber 6 and the water supply port 3 are connected with a pump body 62, thereby realizing the recycling of water resources and avoiding the waste of water resources. At the same time, the floating object collection chamber 5 and the sand and gravel collection chamber 6 are connected with a connecting port 8, and a filter net 81 is provided on the connecting port 8. By connecting the floating object collection chamber 5 with the sand and gravel collection chamber 6, the recycling effect of the water source is further enhanced.

[0055] Through the above structure, on the basis of the structure of the first embodiment, the present invention realizes the recycling of water resources and avoids the waste of water resources by connecting the water supply port 3 with the sand and stone collection chamber 6. At the same time, by connecting the floating object collection chamber 5 with the sand and stone collection chamber 6, the recycling effect of water resources is further enhanced.

[0056] Combination Figure 3 , an aeration member 82 is provided below the filter screen 81. There are multiple communication ports 8, and the aeration member 82 is a first fan to make the water in the floating object collection chamber 5 present a second fluidized bed structure, and floating objects with a density less than that of water rise. The floating object collection chamber 5 is connected to the water supply pipe 61, and a second fan 83 with a downward sealing is further provided inside the communication port 8 to make the sand and stone collection chamber 6 present a third fluidized bed structure, and floating objects with a density greater than that of water fall.

[0057] Therefore, the floating object collecting chamber 5 in the present invention is designed as a second fluidized bed structure and the sand and gravel collecting chamber 6 is designed as a third fluidized bed structure, ensuring that the floating objects in the floating object collecting chamber 5 float on the top of the floating object collecting chamber 5 to prevent the floating objects from being mixed into the water supply pipe 61, and the sand and gravel in the sand and gravel collecting chamber 6 are deposited at the bottom of the sand and gravel collecting chamber 6 to prevent the sand and gravel from being mixed into the water supply pipe 61, thereby optimizing the cleanliness of the recycled water.

[0058] It is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
