Description

Technical Field

[0001] The invention relates to the technical field of fans, and in particular to a high-efficiency energy-saving fan capable of preventing static electricity. Background Art

[0002] With the development of production technology, it is urgent to develop medium flow, medium and high pressure material conveying fans. Conventional national standards are used for material conveying and polishing machine fan selection (parameters are flow rate 6500 ~ 7800m3 / h, full pressure 8000pa, t = 20 ℃, atmospheric pressure Pa = 101325Pa). The speed is changed by selecting national standard fans. For example, 9-19-7.1C has a power distribution of 30Kw and a speed of 2500rpm. Not only is the motor power distribution relatively large, but it is also a C-type belt drive. Or the selection of 9-19-7.1D uses variable frequency speed regulation. Compared with the A-type fan drive, it adds components such as bearing boxes, which brings about the disadvantages of large space occupation. The C-type belt drive is not suitable for use in some occasions with anti-static requirements, and the maintenance is relatively complicated.

[0003] Among them, the PGJ22-2A (power 22Kw speed 2940rpm) fan can meet the flow rate of 6500~7800m3 / h, full pressure 8000pa, t=20℃, atmospheric pressure Pa=101325Pa, and the full pressure efficiency is more than 82%. However, this type of fan adopts the connection between the output shafts, which greatly reduces the generation of external static electricity compared to the C-type belt drive. However, its fan blades are generally coated with more anti-rust paint, which causes the iron or aluminum fan blades to become insulators, causing the fan blades to continuously rub against the air when rotating at high speed and generate a certain charge, thereby increasing the probability of subsequent static electricity generation. The charged fan blades are more likely to absorb dust, resulting in changes in the weight and exhaust volume of the fan blades themselves, increasing the burden on the output shaft, and the dust removal environment is generally dry. The generation of static electricity is easy to cause dust explosions in locations with high dust content. Therefore, it is necessary to design an anti-static and energy-saving fan. Summary of the invention

[0004] The object of the present invention is to provide an anti-static and energy-saving fan to solve the problem that the A-type fan proposed in the above background technology adopts the connection method between the output shafts, which greatly reduces the generation of external static electricity compared with the C-type belt drive, but its blades are generally coated with more anti-rust paint, which causes the iron or aluminum blades to become insulators, so that the blades constantly rub against the air when rotating at high speed and generate a certain charge, thereby increasing the probability of subsequent static electricity generation.

Then, through the water flow effect of the water distribution trough and the dispersion effect of the water distribution hole, the water can be distributed more evenly. At the same time, the area of ​​the water curtain is increased, so that the adsorption effect and wetting effect of the water curtain are better, which further improves the use effect of the device.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-9 , an embodiment provided by the present invention:

[0029] A high-efficiency and energy-saving fan capable of preventing static electricity comprises a device body 1, the device body 1 comprises a support frame 110, an exhaust bin 111 is fixedly mounted on one side of the support frame 110, a motor 112 is fixedly mounted on one end of the support frame 110 on one side of the exhaust bin 111, and the output end of the motor 112 extends to the inside of the exhaust bin 111, an inlet fan 113 is sleeved on the output end of the motor 112, a wetting cylinder 114 is fixedly mounted on one end of the motor 112, a water storage annular sleeve 115 is embedded and sleeved on the wetting cylinder 114, and the inner surface of the wetting cylinder 114 on one side of the water storage annular sleeve 115 is A support rod 116 is fixedly installed, and a rotating shaft 117 is sleeved on the support rod 116 through a bearing. A mounting sleeve 118 is sleeved on the outer side of the rotating shaft 117. A kinetic fan 119 is sleeved on the rotating shaft 117 on one side of the mounting sleeve 118. A stabilizing frame 120 is sleeved on the rotating shaft 117 at one end of the kinetic fan 119 through a rotating shaft, and both sides of the stabilizing frame 120 are connected to the inner wall of the wetting cylinder 114. A water distribution mechanism 2 is provided on the outer surface of the mounting sleeve 118, and the number of the water distribution mechanisms 2 is five. The water distribution mechanism 2 includes a fixed seat 210, and the fixed seat 210 is connected to the mounting sleeve 118. On the sleeve 118, a water dividing rod 211 is fixedly installed at one end of the fixing seat 210, and a water retaining mechanism 3 is provided inside the wetting cylinder 114 on one side of the support rod 116. In this way, the wind pressure formed after the inlet fan 113 is started drives the kinetic fan 119 to rotate, thereby driving multiple water dividing rods 211 to rotate, so that the water dividing rods 211 drive the water in the water storage annular sleeve 115 to form a certain amount of water curtain, so that the water curtain can adsorb dust in the air to a certain extent, reduce the dust density in the air entering the inlet fan 113, and then reduce the dust adsorbed on the fan blades. density, thereby reducing the impact of dust adhesion on the inlet fan 113, and at the same time using the water curtain to moisten the airflow to enhance the conductivity of the air, so that the charge on the surface of the inlet fan 113 is taken away when the air and the fan blades come into contact, avoiding the accumulation of charges on the surface of the inlet fan 113 to form electrostatic discharge. Combined with the wetting and dust reduction characteristics of the water curtain, the device can avoid dust explosions when used in dusty places. At the same time, the relatively humid airflow can take away more heat from the inlet fan 113, which helps to cool the output shaft of the motor 112.

[0030] Furthermore, the bending direction of the blades of the inlet fan 113 is opposite to the rotation direction of the impeller, and the outlet installation angle is less than ninety degrees. This makes the fan operating current curve smooth and changes slowly, and is more energy-saving and reduces operating costs. It has a wide performance range, stable efficiency, and reliable operation, which can meet the needs of small and medium-distance material transportation, polishing machines, forced cooling, and ventilation and dust removal system groups with parallel complex pipe networks. At the same time, the rear bending direction can reduce the noise when the inlet fan 113 rotates.

[0031] Furthermore, the motor 112 can be replaced with a belt drive, a coupling drive, a chain drive or other transmission modes according to humidity, temperature and other conditions. This can increase the applicability and variability of the device, allowing the device to be used in more occasions, thereby making the device more user-friendly.

[0032] Furthermore, a water intake block 212 is fixedly installed at one end of the water dividing rod 211, a water dividing groove 213 is opened inside the water dividing rod 211, a water intake groove 214 is opened inside the water intake block 212, and the water dividing groove 213 and the water intake groove 214 are communicated, and water dividing holes 215 are evenly opened on the inner wall of the water dividing groove 213. In this way, the water storage effect of the water dividing groove 213 is utilized to allow the water intake block 212 to store more water, and then the water flow effect of the water dividing groove 213 and the dispersion effect of the water dividing holes 215 are used to make the water more evenly distributed, and at the same time, the area of ​​the water curtain is increased, so that the adsorption effect and wetting effect of the water curtain are better, which further improves the use effect of the device. At the same time, the structure of the mechanism is simple, which is convenient for the staff to promote production, and also makes the device more stable.

[0033] Furthermore, one side of the water intake trough 214 is in an arc shape, and one end of the water diversion trough 213 is in a slope shape. In this way, the arc shape of the water intake trough 214 allows water to flow into the water diversion trough 213 more quickly. Subsequently, the inclined surface of the water diversion trough 213 and the rotation of the water diversion rod 211 are utilized to allow the water to flow toward the multiple water diversion holes 215 more quickly, thereby preventing the water from flowing out of a few water diversion holes 215, thereby further ensuring the effective generation area of ​​the water curtain.

[0034] Furthermore, the water retaining mechanism 3 includes a top filter half ring 310, which is connected to the inner surface of the wetting cylinder 114, a top sponge half ring 311 is fixedly installed on the side of the top filter half ring 310 close to the support rod 116, and the outer surface of the top sponge half ring 311 is connected to the inner surface of the wetting cylinder 114, a bottom filter half ring 312 is fixedly installed on the inner surface of the wetting cylinder 114 on the side of the top filter half ring 310 away from the support rod 116, a bottom sponge half ring 313 is fixedly installed on the side of the bottom filter half ring 312 close to the top filter half ring 310, and the bottom sponge The outer surface of the semi-ring 313 is connected to the inner surface of the wetting cylinder 114, and a return water mechanism 4 is provided on the inner wall of the wetting cylinder 114 inside the top filter semi-ring 310 and the bottom sponge semi-ring 313. In this way, the porous characteristics of the top filter semi-ring 310 and the top sponge semi-ring 311 are utilized to block the water curtain to prevent excessive water curtain from entering the exhaust bin 111 with the air flow. At the same time, the top filter semi-ring 310 and the bottom filter semi-ring 312 are installed in an offset manner, so that the water curtain condenses downward at the bottom end of the inner wall of the wetting cylinder 114 after being blocked and will not continue to move into the exhaust bin 111.

[0035] Furthermore, the return water mechanism 4 includes a return water box 410, which is embedded and installed on the wetting cylinder 114, a return water cylinder 411 is embedded and installed on one side of the return water box 410, and the other side of the return water cylinder 411 is embedded and installed on the water storage annular sleeve 115, a drainage hole 412 is opened at one end of the water storage annular sleeve 115, a drainage plug 413 is inserted into the drainage hole 412, and the outer side of the wetting cylinder 114 is sleeved with an auxiliary support mechanism 5, so that the collection effect of the return water box 410 and the connection effect of the return water cylinder 411 on the return water box 410 and the water storage annular sleeve 115 can be used to keep the liquid level in the water storage annular sleeve 115 and the liquid level in the return water box 410 can be kept parallel, that is, the water can better flow back to the water storage annular sleeve 115, and at the same time, the waste liquid can be quickly discharged by cooperating with the drainage hole 412 and the drainage plug 413.

[0036] Furthermore, the auxiliary support mechanism 5 includes a rubber ring 513, the rubber ring 513 is sleeved on the outer surface of the wetting cylinder 114, the auxiliary support ring 512 is sleeved on the outer surface of the rubber ring 513, and auxiliary support rods 511 are fixedly installed on both sides of one end of the auxiliary support ring 512, and auxiliary support plates 510 are fixedly installed on one end of the two auxiliary support rods 511. In this way, the cushioning effect of the rubber ring 513 and the supporting effect of the auxiliary support ring 512 and the auxiliary support rod 511 can be used to make the wetting cylinder 114 more firmly fixed, reduce the vibration of the wetting cylinder 114 when air flows through, reduce the vibration of each connecting part in the wetting cylinder 114, and avoid premature loosening.

[0037] Working principle: When using this device, first add a certain amount of water into the water storage annular sleeve 115. The water will flow into the return water box 410 due to the existence of the return water cylinder 411. When the water is added, the motor 112 can be started by connecting the external power supply.

[0038] When the motor 112 is started, it will drive the air intake fan 113 to rotate, so that its airflow carries the dust into the wetting cylinder 114. At the same time, when the airflow enters the wetting cylinder 114, it will drive the kinetic fan 119 to rotate. When the kinetic fan 119 rotates, it will drive the rotating shaft 117 to rotate, thereby driving the installation sleeve 118 and the water dividing rod 211 to rotate, so that the water intake block 212 fills the water into the water intake trough 214. Subsequently, because the position of the water intake trough 214 is raised as the installation sleeve 118 rotates, the water enters the water dividing trough 213 under the influence of gravity, and the water flows along the inclined surface of the water dividing trough 213 and is discharged from multiple water dividing holes 215. Combined with the rotation of the installation sleeve 118, a certain water curtain is formed.

[0039] The water curtain will moisten the airflow and simply remove dust. At the same time, the water curtain will be driven by the airflow so that the falling position is not above the water storage ring sleeve 115. When the water curtain hits the top filter half ring 310 or the bottom filter half ring 312, the airflow will pass through the top filter half ring 310 and the bottom filter half ring 312, and the water will be absorbed by the top sponge half ring 311 and the bottom sponge half ring 313 and continue to move downward due to the gravity of the water. Finally, the water will gather into the return water box 410.

[0040] The dust content of the airflow after the water curtain treatment will be reduced and the airflow will be moistened. When the airflow enters the exhaust bin 111 and contacts the inlet fan 113, the water will act as a charge carrier to transfer the charge on the inlet fan 113 and finally be discharged with the airflow.

[0041] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
