Description

A self-rotating spray dust removal device and dust removal method thereof

Technical Field

The invention belongs to the field of spray dust removal, and in particular relates to a self-rotating spray dust removal device and a dust removal method thereof.

Background Art

Sprayers generally use power drive devices such as electric motors and hydraulic motors to drive blades to generate wind pressure, which is output along the wind tube. A nozzle is installed at the outlet of the wind tube. The mist particles sprayed by the nozzle are transported to a longer distance through high-speed air flow, and finally agglomerate with dust particles and settle. Because conventional sprayers need to be equipped with drive devices and wind tubes, conventional sprayers are large in size, and driving them through electric motors and hydraulic motors consumes a lot of energy. In addition, the driving equipment needs to be frequently maintained and repaired when working in a high-temperature and high-dust environment for a long time, which shortens the service life of the equipment, increases the overall cost, and also increases the maintenance cost.

For small-scale fixed-point dust reduction, a single or multiple nozzles are fixed near the dust reduction point. The mist particles rely on the kinetic energy generated by the water pressure when sprayed from the nozzle to spread by themselves, collide with the dust, agglomerate, and settle during the diffusion to achieve dust reduction. Although the dust reduction method using a fixed single or multiple nozzles has a simple structure and low cost, the dust reduction effect is limited and it is only suitable for small-scale dust reduction. The area covered by the spray is quite limited.

Therefore, there is an urgent need for a spray dust removal device with simple structure, energy saving, good dust removal effect and large dust removal range.

As shown in Figures 1 to 7, the present invention provides a self-rotating spray dust removal device, comprising a spray system, a connecting seat 1, and a plurality of blades 2 arranged in a circular array on the connecting seat 1, wherein the connecting seat 1 and the blades 2 constitute a fan structure, wherein the blades 2 are a rotatable structure, thereby driving air flow during rotation, specifically, a plurality of blades 2 can be rotatably arranged on the connecting seat 1, thereby realizing the rotation of the blades 2, and a plurality of blades 2 can also be fixedly arranged on the connecting seat 1, and the connecting seat 1 can be rotated relative to the installation position of the present self-rotating spray dust removal device, thereby realizing the rotation of the blades 2;

The spray system includes a nozzle arranged on the blade 2 and a liquid supply structure 5 for supplying liquid to the nozzle, the liquid supply structure 5 is used to provide liquid to the nozzle, thereby causing the nozzle to spray, wherein the nozzle includes a first nozzle 3 arranged on the back of the blade 2 and/or a second nozzle 4 arranged at the end of the blade 2. It should be noted that the back of the blade 2 refers to the air intake side of the blade 2, and correspondingly, the front of the blade 2 refers to the air blowing side, and the end of the blade 2 refers to the end of the blade 2 away from the connecting seat 1, and the end of the blade 2 connected to the connecting seat 1 is the root end of the blade. The present invention is arranged with a nozzle on the blade 2, and only the first nozzle 3 or only the second nozzle 4 can be arranged on the blade 2, or the first nozzle 3 and the second nozzle 4 can be arranged at the same time, wherein the first nozzle 3 arranged on the back of the blade 2 can generate a reverse thrust to drive the blade 2 to rotate, thereby causing the blade 2 to drive the air circulation to transport the spray to the dust removal space. On the basis of, on the one hand, the back of the blade 2 is used as a negative pressure surface, the sprayed mist particles can be directly guided to the front of the blade 2, and then enter the dust removal space together with the flowing air, shortening the contact distance between the mist particles and the flowing air, and the mist particles can be directly carried by the flowing air after being sprayed from the first nozzle 3, ensuring the coordination of most of the mist particles and the airflow, and on the other hand, because it is arranged on the back of the blade 2, the impact on the air flow field when the blade 2 rotates can be minimized to ensure the efficiency of the blade 2; wherein, the second nozzle 4 arranged at the end of the blade 2 can also generate a reverse thrust to drive the blade 2 to rotate, and then the blade 2 drives the air circulation to transport the spray to the dust removal space, on the one hand, it can increase the force arm length of the reverse thrust, and then improve the effect of the reverse thrust on the basis of the same liquid pressure, and increase the rotation speed of the blade 2, and on the other hand, it can make the spray coverage area larger, and then remove dust in a large area of space. Preferably, the first nozzle 3 and the second nozzle 4 are arranged at the same time, which can not only ensure sufficient rotation driving force of the blade 2, but also ensure sufficient mixing degree of mist particles and airflow, and ensure dust reduction effect.

The nozzle sprays, and the reverse thrust generated by the spray drives the blade 2 to rotate. The rotation of the blade 2 drives the air to flow, and the flowing air drives the mist particles in the spray to be transported to the dust removal space for dust reduction. With such an arrangement, the rotation of the blade 2 and the provision of mist particles can be achieved simultaneously through the single power of the high-pressure liquid, thereby simplifying the structure and reducing costs and energy consumption on the basis of ensuring the range of action of the mist particles.

The self-rotating spray dust removal device provided by the present invention utilizes the reverse thrust generated by the nozzle spray to drive the blades to rotate, so that the blades do work to drive the air flow. During spraying, the mist particles collide with the dust particles in the space, agglomerate and settle under the joint action of their own spray kinetic energy and the kinetic energy obtained by the air flow, thereby achieving dust removal. Under the joint action of multiple energies, the mist particles with greater kinetic energy can collide with the dust particles quickly and repeatedly and agglomerate. When the mist particles and dust particles are bonded to a certain volume weight, they are settled. It has the advantages of high dust reduction efficiency, good effect, long diffusion distance and wide dust reduction range. The reverse thrust generated by the nozzle spray on the conventional spray device will be converted into internal stress to overcome and offset it. The present invention makes full use of the reverse thrust to achieve self-rotating diffusion spray without the need for other additional energy sources. The structure has the advantages of being simple and reliable, maintenance-free, low cost, and more energy-saving and environmentally friendly. Moreover, the nozzle is directly arranged on the blade 2. Compared with the method of arranging the nozzle on the connecting seat 1 (the rotating seat 12 of the connecting seat 1), on the one hand, the length of the force arm of the reverse thrust can be increased, thereby improving the rotation driving effect of the blade 2. On the other hand, the mist particles can be directly in contact with the flowing air after being sprayed, thereby improving the dust reduction efficiency and effect. Compared with the method of arranging the nozzle on the connecting seat 1 (the rotating seat 12 of the connecting seat 1) by arranging a connecting rod separately, the structure can be simplified. When the blade 2 is rotatably arranged on the connecting seat 1, the nozzle and the blade 2 can also be rotated synchronously, providing a variety of dust reduction installation modes, and meeting the dust reduction needs of different working conditions on the basis of good dust removal effect.

In one embodiment, the spray port aperture of the first nozzle 3 is smaller than the spray port aperture of the second nozzle 4 .

In this embodiment, the blade 2 is provided with both the first nozzle 3 and the second nozzle 4, wherein the first nozzle 3 with a small spray port aperture produces fine mist particles, small thrust, and good fluidity after the mist particles are mixed with the air, which increases the amount of mist and provides auxiliary rotational power at the same time. Moreover, the first nozzle 3 with a small spray port aperture is arranged on the blade body of the blade 2. Since the flowing air driven by the rotation of the blade 2 is also mainly at the blade body position, the mixing effect of the fine mist particles and the air can also be ensured, thereby ensuring the amount of mist particles for long-distance dust removal and improving the dust removal effect. Among them, the mist particles produced by the second nozzle 4 with a large spray port aperture are coarse, and the water flow rate of the spray port is large, so that a large thrust can be generated, which can be used as the main power source for the rotation of the blade 2. At the same time, the second nozzle 4 is arranged at the end of the blade 2, which can increase the amount of mist particles on the outside of the blade 2 and increase the range of dust removal. The two work together to ensure the rotational power of the blade 2, and at the same time, the dust reduction effect is good and the dust reduction range is wide.

In one embodiment, a plurality of first nozzles 3 are arranged along the length direction of the blade 2 to further increase the amount of mist particles and the thrust on the blade 2 .

In one embodiment, the front side of the blade 2 is a concave arc surface, which can increase the efficiency of air flow; the spray direction of the first nozzle 3 is tangent to the arc surface, so that the spray direction of the mist particles is consistent with the flow direction of the air, reducing resistance.

In one of the embodiments, the second nozzle 4 is arranged at the end of the blade 2 through an angle adjustment mechanism, and the angle adjustment axis of the second nozzle 4 is parallel to the rotation axis of the blade 2. In this embodiment, the spray angle of the second nozzle 4 is adjustable, and then the direction of the thrust acting on the blade 2 can be adjusted by adjusting the spray angle of the second nozzle 4, thereby providing different thrusts on the basis of consistent liquid pressure, and at the same time, the range of action of the spray can also be adjusted, thereby realizing different spray modes.

In one of the embodiments, one end of the root of the blade 2 is arranged on the connecting seat 1 through an angle adjustment mechanism, and the angle adjustment axis of the blade 2 is perpendicular to the rotation axis of the blade 2, so that several blades 2 can be expanded or contracted. In this embodiment, the opening degree of multiple blades 2 can be adjusted to provide different dust removal modes. In addition, the angle of the second nozzle 4 can be adjusted to provide better dust removal effect for different dust removal modes.

Specifically, this embodiment can realize three different dust removal modes, namely, a horizontal large-scale dust removal mode, an umbrella-shaped vertical space dust removal mode, and a vertical small-scale dense fog dust removal mode.

Referring to Figures 1 to 4, the horizontal large-scale dust removal mode is mainly suitable for dust reduction in large spaces and large areas of low altitude areas. At this time, the blade 2 is opened and perpendicular to the rotation axis of the blade 2, and the spray direction of the second nozzle 4 is parallel to the length direction of the blade 2 (the second nozzle 4 does not provide a driving force for the blade 2 at this time). At this time, the maximum spray range and the slowest rotation speed can be obtained, which has the advantages of a wide dust reduction range and a low rotation wind speed, and will not cause secondary dust pollution due to its own blowing. At this time, the pressure of the liquid provided by the liquid supply structure 5 is adjustable, and the appropriate spray distance and blade 2 rotation speed can be obtained by adjusting the water supply pressure.

Refer to Figures 5 and 6, in which the umbrella-shaped vertical space dust removal mode is mainly suitable for three-dimensional dust reduction in small spaces. At this time, the blade 2 is at an acute angle or an obtuse angle to the rotation axis of the blade 2, and the spray direction of the second nozzle 4 is at an acute angle to the length direction of the blade 2. At this time, a suitable spray distance and blade 2 rotation speed can be obtained. Referring to Figure 5, when the blade 2 is tilted upward, a small-range diffused umbrella spray can be obtained, which has the characteristics of large mist volume and fast mist particle diffusion; referring to Figure 6, when the blade 2 is tilted downward, a small-range contracted concentrated spray can be obtained, which has the characteristics of concentrated mist volume and long axial distance of the spray; at the same time, the pressure of the liquid provided by the liquid supply structure 5 is adjustable, and the spray distance and the rotation speed of the blade 2 can be adjusted by adjusting the water supply pressure.

Refer to Figure 7, in which the vertical small-scale dense fog dust removal mode is mainly suitable for dust reduction in narrow and elongated spaces. At this time, the blade 2 is parallel to the rotation axis of the blade 2. This mode can obtain the minimum spray distance and the fastest rotation speed, and has the characteristics of very concentrated mist and small space occupation. In addition, the angle of the second nozzle 4 is adjustable and can provide different rotational forces. At the same time, the pressure of the liquid provided by the liquid supply structure 5 is adjustable. The spray distance and the rotation speed of the blade 2 can be adjusted by adjusting the water supply pressure.

This embodiment can form various dust reduction installation modes such as horizontal large-scale dust removal, umbrella-shaped vertical space dust removal, vertical small-scale dense fog dust removal, etc. by manually or electrically adjusting the angle of the blade 2 and the spray angle of the second nozzle 4. Combined with the adjustment of the water supply pressure, the speed of the blade 2 can be adjusted and the dust reduction space can be adjusted in real time after the equipment is installed, so as to meet the dust reduction needs of different working conditions and improve the dust reduction effect.

In one embodiment, the angle adjustment mechanism includes a hinge structure and an angle locking mechanism arranged on the hinge structure. The hinge structure is adopted, that is, the second nozzle 4 is rotatably arranged on the blade 2, and the blade 2 is rotatably arranged on the connecting seat 1, which can increase the range of angle adjustment and reduce the difficulty of adjustment. The angle locking mechanism can ensure the fixation of the two after the angle adjustment and ensure the operation stability. In other embodiments, the angle adjustment structure can also be implemented in a plug-in manner. For example, a plurality of sockets with different angles are arranged on the connecting seat 1, and the root of the blade 2 is inserted into one of the sockets to achieve angle adjustment. For another example, a plurality of sockets with different angles are arranged at the end of the blade 2, and the second nozzle 4 is inserted into one of the sockets to achieve angle adjustment.

In one embodiment, the hinge structure includes a fixed shaft 6 and a mounting block 7 rotatably arranged on the fixed shaft 6, and the hinge structure has two groups, one group connects the blade 2 and the connecting seat 1, and the other group connects the second nozzle 4 and the blade 2. The fixed shaft 6 of the hinge structure connecting the blade 2 and the connecting seat 1 is arranged on the connecting seat 1 (in the embodiment where the connecting seat 1 includes a fixed seat 11 and a rotating seat 12, the fixed shaft 6 is arranged on the rotating seat 12), and the mounting block 7 is hingedly arranged on the fixed shaft 6, at which time, the blade 2 is fixedly arranged on the mounting block 7; the fixed shaft 6 of the hinge structure connecting the second nozzle 4 and the blade 2 is arranged at the end of the blade 2, and the mounting block 7 is hingedly arranged on the fixed shaft 6, at which time, the second nozzle 4 is fixedly arranged on the mounting block 7. The hinge structure has the characteristics of simple and reliable structure, convenient and quick angle adjustment, and a large adjustable range.

In this embodiment, the angle locking mechanism includes a turbine 8 fixedly arranged on the fixed shaft 6 and a worm 9 rotatably arranged on the mounting block 7 and meshing with the turbine 8. By rotating the worm 9, the angle of the mounting block 7 on the fixed shaft 6 can be adjusted, thereby adjusting the angle of the blade 2 and the second nozzle 4. The turbine worm structure used as the angle locking mechanism has the characteristics of high reliability, self-locking function, and ability to withstand large rotational thrust; at the same time, the rotation of the worm 9 can be adjusted manually or electrically. In addition, angle marks are engraved at the positions of the blades 2 and the second nozzle 4 to ensure that the angles of each blade 2 or the second nozzle 4 are consistent during manual adjustment. When electric adjustment is adopted, a stepper or servo motor should be used to ensure angle consistency.

In one embodiment, the connecting seat 1 includes a fixed seat 11 and a rotating seat 12, the rotating seat 12 is rotatably set on the fixed seat 11, and the blade 2 is set on the rotating seat 12. In this embodiment, the rotation of the blade 2 will drive the rotating seat 12 to rotate, and the rotating seat 12 will simultaneously drive all other blades 2 to rotate, which can ensure the rotation synchronization rate of all blades 2. Compared with the method in which the blade 2 is rotatably set on the connecting seat 1, the structure is simpler and more convenient for the arrangement of the liquid supply structure 5.

In one of the embodiments, the liquid supply structure 5 includes a liquid supply cavity 51 arranged in the rotating seat 12, a liquid inlet channel 52 arranged on the fixed seat 11 and connected to the liquid supply cavity 51, and a liquid supply channel 53 arranged in the blade 2 and connected to the liquid supply cavity 51, the first nozzle 3 and/or the second nozzle 4 are connected to the liquid supply channel 53, wherein the liquid inlet channel 52 and the liquid supply cavity 51 provide liquid for the liquid supply channels 53 of multiple blades 2, preferably, and each blade 2 is correspondingly provided with a liquid supply channel 53, each liquid supply channel 53 is connected to the liquid supply cavity 51 through a connecting pipe 54, in the embodiment where the blade 2 is rotatably arranged on the connecting seat 1, the connecting pipe 54 is a hose, so that when the blade 2 rotates to any angle, the liquid supply channel 53 can be connected to the liquid supply cavity 51, when the blade 2 is provided with both the first nozzle 3 and the second nozzle 4, the liquid supply channel 53 extends from the root of the blade 2 to the end, thereby simultaneously connecting at least one first nozzle 3 and the second nozzle 4 at the end, thereby simplifying the liquid supply structure 5. Among them, the liquid inlet channel 52 and the liquid supply chamber 51 are rotationally matched, that is, the liquid inlet channel 52 is always in a stationary state, and the other end is connected to the water supply mechanism, which simplifies the connection difficulty between the water supply mechanism and the self-rotating spray dust removal device, and the liquid supply chamber 51 is in a rotating state to provide high-pressure liquid to each blade 2.

The liquid supply structure 5 in this embodiment can provide liquid of the same pressure to the first nozzle 3 and/or the second nozzle 4 of multiple blades 2, thereby ensuring that the rotational driving force of each blade 2 is consistent and improving the rotational stability. At the same time, it only needs to be connected to an external water supply pipe through the liquid inlet channel 52. The overall structure of the liquid supply structure 5 is simple and reliable to use.

With reference to Figures 5 and 6, in the umbrella-shaped vertical space dust removal mode, the blade 2 is at an acute angle or an obtuse angle with the rotation axis of the blade 2, the spray direction of the second nozzle 4 is at an acute angle with the length direction of the blade 2, and the pressure of the liquid provided by the liquid supply structure 5 is adjustable; this mode is suitable for regional dust reduction in narrow and elongated spaces. With reference to Figure 5, when the blade 2 is tilted upward, a small-range diffused umbrella-shaped spray can be obtained, which has the characteristics of large mist volume and fast mist particle diffusion; with reference to Figure 6, when the blade 2 is tilted downward, a small-range contracted concentrated spray can be obtained, which has the characteristics of concentrated mist volume and long axial distance from the spray; and the pressure of the liquid provided by the liquid supply structure 5 is adjustable, and the spray distance and the rotation speed of the blade 2 can be adjusted by adjusting the water supply pressure.

Referring to Figure 7, in the vertical small-scale dense fog dust removal mode, the blade 2 is parallel to the rotation axis of the blade 2, and the pressure of the liquid provided by the liquid supply structure 5 is adjustable; this mode is suitable for dust reduction in narrow and elongated spaces. This mode can obtain the minimum spray distance and the fastest rotation speed, and has the characteristics of very concentrated fog volume and small space occupation.

The dust removal steps of the horizontal large-scale dust removal mode, the umbrella-shaped vertical space dust removal mode and the vertical small-scale dense fog dust removal mode are as follows: the liquid supply structure 5 provides high-pressure liquid to the nozzle, the nozzle sprays, the spray generates a reverse thrust to drive the blade 2 to rotate, the rotation of the blade 2 drives the air to flow, and the flowing air drives the mist particles in the spray to be transported to the dust removal space for dust reduction.

This method can form a variety of dust reduction installation modes such as horizontal large-scale dust removal, umbrella-shaped vertical space dust removal, vertical small-scale dense fog dust removal, etc. by manually or electrically adjusting the angle of the blade 2 and the spray angle of the second nozzle 4. Combined with the adjustment of the water supply pressure, the real-time state adjustment of the adjustable speed of the blade 2 and the variable dust reduction space after the equipment is installed can be achieved to meet the dust reduction needs of different working conditions and improve the dust reduction effect.
