[0003] After searching, the invention patent with Chinese patent number CN108167206B discloses a centrifugal fire smoke exhaust fan, including a base, a shell penetrated through the top of the base, and a buffer device is fixedly connected between the two sides of the bottom of the shell and the two sides of the bottom of the inner wall of the base, and a dust cover is fixedly connected to the right side of the top of the shell, and the inside of the dust cover is fixedly connected to a first motor, and the output shaft of the first motor is fixedly connected to a first pulley. The present invention relates to the technical field of fire fighting equipment. The centrifugal fire smoke exhaust fan improves the heat dissipation effect of the motor by placing the motor externally, and prevents dust in the air from entering the motor through the use of a dust cover, thereby improving the service life of the motor, and can provide buffer protection for the device to prevent large vibrations and reduce noise. When the device is working, the first filter plate and the second filter plate can be shaken to prevent the filter plates from being blocked during operation and affecting the normal use of the device.

[0021] The beneficial effects of the present invention are:

[0022] 1. The present invention uses a filtering mechanism and a spraying mechanism in coordination. When the centrifugal fire-fighting fan is working, the smoke entering the air inlet pipe is filtered by the filtering mechanism, so that the dust particles in the smoke are blocked. At the same time, the spraying mechanism works synchronously. When the spraying mechanism is working, clean water will flow in the heat exchange tube in the filtering mechanism, so that the clean water absorbs the temperature of the smoke and reduces the temperature of the smoke, thereby reducing the probability of the wind wheel being corroded. The clean water after absorbing the smoke temperature will be sprayed into the smoke through the spraying mechanism. At this time, since the clean water has a temperature, the atomization efficiency of the clean water can be higher, so that the atomized clean water can more comprehensively absorb the pollutant gases in the smoke, further reducing the probability of the wind wheel being corroded, while providing good protection for the environment.

[0023] 2.

[0024] 3. The present invention can filter and block water-insoluble substances in flue gas through the operation of the dehydration mechanism, and at the same time enable the first sponge and the second sponge in the dehydration mechanism to absorb the moisture contained in the flue gas after water mist treatment, thereby preventing the water mist containing pollutant gases and fine dust dissolved therein from directly acting on the wind wheel, causing the wind wheel to be corroded, thereby providing good protection for the wind wheel and extending the service life of the wind wheel.

[0025] 4. The present invention enables the dewatering mechanism to drive the spiral plate to slide back and forth through the magnetic ring, thereby expanding the mixing range of the spiral plate for water mist and flue gas, and further improving the mixing efficiency of fine dust in the flue gas and pollutant gases dissolved in water. When the spiral plate slides back and forth, it will synchronously drive the filter to move back and forth under the action of the shaking spring, thereby causing the filter and the spiral plate to shake at the same time, so that the particles and droplets adhered to the outer surfaces of the filter and the spiral plate can be detached due to their own shaking, so that the filter and the spiral plate can absorb more particles and droplets, further improving the efficiency of flue gas treatment.

DETAILED DESCRIPTION

[0040] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0041] Example: Figure 1 , Figure 2 , Figure 4 , Figure 5 and Fig. 9 As shown, a centrifugal fire smoke exhaust fan comprises a base 1, an air inlet pipe 9 fixedly connected to the top of the base 1 and fixedly connected to the air suction pipe 3, the top of the base 1 is fixedly connected to the fan, the fan comprises a casing 2 fixedly connected to the top of the base 1, one side of the casing 2 is fixedly connected to the air suction pipe 3, the air suction pipe 3 is fixedly connected to the air inlet pipe 9, one side of the air inlet pipe 9 is sealed and hinged with a cover plate, the arrangement of the cover plate facilitates cleaning of pollutants in the air inlet pipe 9, the top of the casing 2 is fixedly connected to the exhaust pipe 4, the other side of the casing 2 is fixedly connected to the mounting base 5, the top of the mounting base 5 is installed with a motor 6, the output end of the motor 6 is fixedly connected to a rotating shaft 7, the rotating shaft 7 passes through the casing 2 and is rotatably connected to the casing 2, and the rotating shaft 7 extends to the interior of the casing 2, and one end of the rotating shaft 7 located in the casing 2 is fixedly connected to a wind wheel 8.

[0042] The air inlet pipe 9 of the fan is installed in the fire smoke exhaust channel. When in use, the motor 6 is started to make the rotating shaft 7 drive the wind wheel 8 to rotate, so that the wind wheel 8 draws smoke through the suction pipe 3 and the air inlet pipe 9, and makes the smoke enter the casing 2, and finally discharged to the external environment through the exhaust pipe 4.

[0043] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig.11 , Fig.12 and Fig.13 As shown, the centrifugal fire smoke exhaust fan also includes: a filter mechanism 11 installed in the air inlet pipe 9, the filter mechanism 11 is used to filter dust in the smoke, the filter mechanism 11 includes a fixed plate 1105 fixedly connected in the air inlet pipe 9, a shaking spring 1104 is fixedly connected to one side of the fixed plate 1105, the end of the shaking spring 1104 is fixedly connected to a fixed frame 1101, the fixed frame 1101 is attached to the inner surface of the air inlet pipe 9, a filter screen 1102 is fixedly connected in the fixed frame 1101, the filter screen 1102 is fixedly connected to the heat exchange tube 1103, and the heat exchange tube 1103 is used to absorb the heat of the smoke.

[0044] When the wind wheel 8 rotates, the flue gas to be discharged will enter the air inlet pipe 9. The flue gas entering the air inlet pipe 9 first passes through the filter 1102, where the dust in the flue gas is filtered by the filter 1102, and the heat exchange tube 1103 absorbs the temperature of the flue gas, thereby reducing the temperature of the flue gas and preventing the hot flue gas from directly acting on the wind wheel 8, which would accelerate the corrosion of the wind wheel 8. The wind wheel 8 is well protected and the service life of the wind wheel 8 is extended.

[0045] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig. 9 , Fig.10 , Fig.11 and Fig.12As shown, the centrifugal fire smoke exhaust fan also includes: a mixing mechanism 10 arranged in the air inlet pipe 9, the mixing mechanism 10 is used to mix the smoke and clean water (not limited to clean water, and the corresponding liquid can be selected according to the actual situation to absorb the substances in the smoke), the mixing mechanism 10 is located between the filtering mechanism 11 and the water removal mechanism 12, the mixing mechanism 10 includes a connecting shaft 1001 fixedly connected to the middle of the wind wheel 8 at one end, the other end of the connecting shaft 1001 is fixedly connected to a hexagonal prism 1002, the outer surface of the hexagonal prism 1002 is slidably connected to a sleeve pipe 1003, the outer surface of the hexagonal prism 1002 and the sleeve pipe 1003 are The inner surface is adapted, the outer surface of the sleeve tube 1003 is fixedly connected with a spiral plate 1004, the spiral plate 1004 is arranged in a mesh form, one end of the sleeve tube 1003 is fixedly connected with a magnetic ring 1005, the other end of the sleeve tube 1003 is fixedly connected with a cleaning rod 1006, the cleaning rod 1006 is arranged in a "T" shape, the cleaning end of the cleaning rod 1006 is provided with bristles, the cleaning rod 1006 penetrates the filter screen 1102 and is rotatably connected to the filter screen 1102, the cleaning end of the cleaning rod 1006 is in contact with the air inlet side of the filter screen 1102, and the filter screen 1102 and the heat exchange tube 1103 are cleaned by the bristles.

[0046] When the wind wheel 8 rotates, the connecting shaft 1001 will rotate, thereby driving the hexagonal prism 1002 to rotate. Since the outer surface of the hexagonal prism 1002 is slidably connected to the sleeve 1003, the spiral plate 1004 will be driven to rotate through the sleeve 1003, so that the spiral plate 1004 can capture fine dust in the flue gas during the rotation, thereby achieving further purification of the flue gas. In this process, the cleaning rod 1006 will also clean the filter 1102 and the heat exchange tube 1103, ensuring the filtering efficiency of the filter 1102 on the flue gas and the efficiency of the heat exchange tube 1103 in reducing the flue gas temperature. At the same time, it prevents the dust in the flue gas from adhering to the outer surface of the filter 1102 and the heat exchange tube 1103 for a long time, causing the filter 1102 and the heat exchange tube 1103 to be corroded, thereby well protecting the filter 1102 and the heat exchange tube 1103.

[0047] like Figure 2 , Figure 4 , Figure 6 , Figure 7 , Fig. 9 , Fig.10 , Fig.11 and Fig.12As shown, the dewatering mechanism 12 is fixedly connected in the air inlet pipe 9, and the dewatering mechanism 12 is used to remove moisture from the smoke, and drives the spraying mechanism 13 to work through the driving mechanism 14. The dewatering mechanism 12 includes a reciprocating plate 1202 threadedly connected to the connecting shaft 1001 through a reciprocating wire 1201, and the connecting shaft 1001 penetrates the reciprocating plate 1202. The reciprocating plate 1202 fits the inner surface of the air inlet pipe 9, and one end of the reciprocating plate 1202 is fixedly connected to a first extrusion net 1203, and one side of the reciprocating plate 1202 is fixedly connected to a connecting rod 1204, and the end of the connecting rod 1204 is fixedly connected to a magnetic ring 1205, and the magnetic properties of the magnetic ring 1205 and the magnetic ring 1005 are opposite, and a first fixed net 1206 is fixedly connected in the air inlet pipe 9, and a first sponge 1207 is fixedly connected between the first fixed net 1206 and the first extrusion net 1203, and the other end of the reciprocating plate 1202 is fixedly connected There is a second extrusion net 1208, the first extrusion net 1203 and the second extrusion net 1208 are both in contact with the inner surface of the air inlet pipe 9, a second fixed net 1209 is fixedly connected in the air inlet pipe 9, a second sponge 1210 is fixedly connected between the second fixed net 1209 and the second extrusion net 1208, a plurality of through holes are provided in the first sponge 1207 and the second sponge 1210 to facilitate the passage of airflow, the first sponge 1207 and the second sponge 1210 are spaced from the bottom of the air inlet pipe 9, the driving mechanism 14 includes a piston rod 1401, a return spring 1402 is sleeved on the outer surface of the piston rod 1401, one end of the piston rod 1401 is fixedly connected to a connecting rope 1403, the end of the connecting rope 1403 away from the piston rod 1401 is fixedly connected to the reciprocating plate 1202, a guide pipe 1404 is fixedly connected to the air inlet pipe 9, and the connecting rope 1403 slides through the guide pipe 1404.

[0048] The smoke after the fine dust is captured by the spiral plate 1004 will pass through the first sponge 1207 and the second sponge 1210, and the first sponge 1207 and the second sponge 1210 will purify the smoke again, and when the connecting shaft 1001 rotates, it will drive the reciprocating wire 1201 to rotate, so that the reciprocating plate 1202 slides back and forth. When the reciprocating plate 1202 slides back and forth, the first extrusion net 1203 and the second extrusion net 1208 will reciprocate and squeeze the first sponge 1207 and the second sponge 1210, and When the first squeezing net 1203 squeezes the first sponge 1207, the second squeezing net 1208 changes the squeezing state of the second sponge 1210 into a releasing state. In addition, during the back-and-forth sliding of the reciprocating plate 1202, the connecting rope 1403 reciprocates the spray mechanism 13 through the piston rod 1401, so that the spray mechanism 13 works under the reciprocating pull of the piston rod 1401 and the action of the return spring 1402, thereby causing the spray mechanism 13 to inject clean water at room temperature into the heat exchange tube 1103, and causing the spray mechanism 13 to 13 intermittently sprays water mist into the flue gas. During this process, since the clean water absorbs the temperature of the flue gas, the water mist sprayed into the flue gas by the spray mechanism 13 has a larger atomization area, so that the atomized clean water can more comprehensively absorb the pollutant gases in the flue gas (the pollutant gases include acidic gases, alkaline gases, polar or water-soluble organic compound gases, and some heavy metal vapors (such as mercury vapor), etc., and in addition, dust, carbon black and other particulate matter in the flue gas can also be captured by water), further reducing the probability of the wind wheel 8 being corroded, and at the same time providing good protection for the environment. Moreover, since the spiral plate 1004 is configured in a mesh form, the spiral plate 1004 can better capture the water mist mixed with the gas and dust to achieve the purpose of purifying the flue gas. Moreover, the first sponge 1207 and the second sponge 1210 can also absorb the moisture contained in the flue gas after the water mist treatment, preventing the water mist containing the pollutant gases and fine dust from directly acting on the wind wheel 8, causing the wind wheel 8 to be corroded, providing good protection for the wind wheel 8, and extending the service life of the wind wheel 8.

[0049] In addition, when the reciprocating plate 1202 slides back and forth, when the reciprocating plate 1202 moves toward the direction of the sleeve tube 1003, the magnetic circle 1205 will be close to the magnetic ring 1005, so that the magnetic circle 1205 and the magnetic ring 1005 are attracted to each other. When the reciprocating plate 1202 moves away from the sleeve tube 1003, the magnetic circle 1205 and the magnetic ring 1005 are attracted to each other, which will pull the outer surface of the sleeve tube 1003 to move in the direction of the reciprocating plate 1202 during the rotation process, thereby driving the spiral plate 1004 to move in the direction of the reciprocating plate 1202, thereby expanding the mixing range of the spiral plate 1004 for water mist and smoke, and further improving the mixing efficiency of fine dust in the smoke and pollutant gases dissolved in water;

[0050] At the same time, due to the movement of the sleeve 1003, the filter 1102 and the fixed frame 1101 are pulled to move through the cleaning rod 1006, so that the shaking spring 1104 is stretched. When the rebound force of the stretched shaking spring 1104 is greater than the magnetic attraction between the magnetic circle 1205 and the magnetic ring 1005, the fixed frame 1101 and the filter 1102 will rebound under the action of the shaking spring 1104, and then the sleeve 1003 drives the spiral plate 1004 to move in the direction of the filter 1102 through the cleaning rod 1006, so that the filter 1102 and the spiral plate 1004 are shaken at the same time, so that the particles and droplets adhered to the outer surfaces of the filter 1102 and the spiral plate 1004 can be detached due to their own shaking, so that the filter 1102 and the spiral plate 1004 can absorb more particles and droplets, thereby further improving the efficiency of flue gas treatment.

A one-way valve is installed in the water suction pipe 1309, so that the piston cylinder 1301 can only absorb water in the air inlet pipe 9 through the water suction pipe 1309. The piston cylinder 1301 is fixedly connected to a drain pipe 1310, and the drainage end of the drain pipe 1310 is fixedly connected to a waste collection box (the waste collection box is a prior art, not shown in the figure, and will not be described in detail). A one-way valve is installed in the drain pipe 1310, so that the water in the air inlet pipe 9 absorbed by the piston cylinder 1301 can only be discharged through the drain pipe 1310. The water suction pipe 1309 passes through the top of the air inlet pipe 9 and extends to the inside of the air inlet pipe 9. The water suction pipe 1309 is located on the exhaust side of the second fixed net 1209.

[0052] In the process of the reciprocating plate 1202 sliding back and forth, the connecting rope 1403 will reciprocate the piston plate 1303 through the piston rod 1401, so that the piston plate 1303 slides back and forth along the inner surface of the piston cylinder 1301 under the reciprocating pulling of the piston rod 1401 and the action of the return spring 1402, so that the piston cylinder 1301 draws clean water from the external water source through the water inlet pipe 1302. In the process of the piston cylinder 1301 drawing water from the external water source, the piston cylinder 1301 will discharge the absorbed water in the air inlet pipe 9 into the waste collection box through the drain pipe 1310. When the piston cylinder 1301 discharges the clean water into the heat exchange tube 1103 through the water injection pipe 1304 and the connecting hose 1305, the clean water entering the heat exchange tube 1103 will absorb the temperature of the flue gas and will pass through The clean water is discharged into the spray box 1307 through the water hose 1306, and is sprayed into the flue gas after being filtered by the filter 1102 through the atomizing nozzle installed in the spray hole 1308. At this time, since the clean water has temperature, the atomization efficiency of the clean water can be higher, so that the atomized clean water can absorb the pollutant gases in the flue gas more comprehensively, further reducing the probability of corrosion of the wind wheel 8, and at the same time providing good protection for the environment. When the piston cylinder 1301 discharges the clean water, the piston cylinder 1301 will extract the water discharged by squeezing the first sponge 1207 and the second sponge 1210 by the first squeezing net 1203 and the second squeezing net 1208 through the water suction pipe 1309, thereby realizing the reuse of the water absorbed by the first sponge 1207 and the second sponge 1210, and improving the utilization rate of resources.

[0053] The specific working principle of the present invention is as follows:

[0054] When in use, the motor 6 is started so that the rotating shaft 7 drives the wind wheel 8 to rotate, and then the wind wheel 8 extracts smoke through the air suction pipe 3 and the air inlet pipe 9. The smoke entering the air inlet pipe 9 first passes through the filter 1102, where the filter 1102 filters the dust in the smoke, and the heat exchange pipe 1103 absorbs the temperature of the smoke, so that the temperature of the smoke is reduced, preventing the hot smoke from directly acting on the wind wheel 8, which causes the corrosion speed of the wind wheel 8 to be accelerated, and the wind wheel 8 is well protected, thereby extending the service life of the wind wheel 8;

[0055] When the wind wheel 8 rotates, the connecting shaft 1001 will rotate, thereby driving the hexagonal prism 1002 to rotate. Since the outer surface of the hexagonal prism 1002 is slidably connected with the sleeve pipe 1003, the spiral plate 1004 will be driven to rotate through the sleeve pipe 1003, so that the spiral plate 1004 can capture fine dust in the flue gas during the rotation process, thereby further purifying the flue gas. In addition, during this process, the cleaning rod 1006 will also clean the filter screen 1102 and the heat exchange tube 1103, thereby ensuring the filtering efficiency of the filter screen 1102 on the flue gas and the efficiency of the heat exchange tube 1103 in reducing the flue gas temperature. At the same time, it prevents the dust in the flue gas from being attached to the outer surface of the filter screen 1102 and the heat exchange tube 1103 for a long time, causing the filter screen 1102 and the heat exchange tube 1103 to be corroded, thereby well protecting the filter screen 1102 and the heat exchange tube 1103.

[0056] The smoke after the fine dust is captured by the spiral plate 1004 will pass through the first sponge 1207 and the second sponge 1210, and the first sponge 1207 and the second sponge 1210 will purify the smoke again, and when the connecting shaft 1001 rotates, it will drive the reciprocating wire 1201 to rotate, so that the reciprocating plate 1202 slides back and forth. When the reciprocating plate 1202 slides back and forth, the first squeezing net 1203 and the second squeezing net 1208 will reciprocate and squeeze the first sponge 1207 and the second sponge 1210, and when the first squeezing net 1203 squeezes the first sponge 1207, the second squeezing net 1208 changes the squeezing state of the second sponge 1210 to the releasing state. In addition, during the back and forth sliding of the reciprocating plate 1202, the connecting rope 1403 will reciprocate the piston plate 1303 through the piston rod 1401, so that the piston plate 1303 slides back and forth along the inner surface of the piston cylinder 1301 under the reciprocating pulling of the piston rod 1401 and the action of the return spring 1402, so that the piston cylinder 1301 draws clean water from the external water source through the water inlet pipe 1302. During the process of the piston cylinder 1301 drawing water from the external water source, the piston cylinder 1301 will discharge the water absorbed from the air inlet pipe 9 into the waste collection box through the drain pipe 1310. In addition, since the spiral plate 1004 is configured in a mesh form, the spiral plate 1004 can better The first sponge 1207 and the second sponge 1210 can also absorb the water contained in the smoke after the water mist treatment, so as to prevent the water mist containing polluting gas and fine dust from directly acting on the wind wheel 8, thereby preventing the wind wheel 8 from being corroded, and thus well protecting the wind wheel 8 and extending the service life of the wind wheel 8. When the piston cylinder 1301 discharges the clean water into the heat exchange tube 1103 through the water injection pipe 1304 and the connecting hose 1305, the clean water entering the heat exchange tube 1103 absorbs the temperature of the smoke and will be discharged into the spray box 1307 through the water delivery hose 1306, and then the spray hole 1306 is used to spray the clean water. 308 is sprayed in the flue gas after being filtered by the filter 1102. At this time, the clean water has a higher atomization efficiency because of its temperature, so that the atomized clean water can absorb the pollutant gas in the flue gas more comprehensively, further reducing the probability of the wind wheel 8 being corroded, and at the same time, the environment is well protected. When the piston cylinder 1301 discharges the clean water, the piston cylinder 1301 will extract the water discharged by squeezing the first sponge 1207 and the second sponge 1210 by the first squeezing net 1203 and the second squeezing net 1208 through the water suction pipe 1309, thereby realizing the reuse of the water absorbed by the first sponge 1207 and the second sponge 1210 and improving the utilization rate of resources;

[0057] In addition, when the reciprocating plate 1202 slides back and forth, when the reciprocating plate 1202 moves toward the direction of the sleeve tube 1003, the magnetic circle 1205 will be close to the magnetic ring 1005, so that the magnetic circle 1205 and the magnetic ring 1005 are attracted to each other. When the reciprocating plate 1202 moves away from the sleeve tube 1003, the magnetic circle 1205 and the magnetic ring 1005 are attracted to each other, which will pull the outer surface of the sleeve tube 1003 to move in the direction of the reciprocating plate 1202 during the rotation process, thereby driving the spiral plate 1004 to move in the direction of the reciprocating plate 1202, thereby expanding the mixing range of the spiral plate 1004 for water mist and smoke, and further improving the mixing efficiency of fine dust in the smoke and pollutant gases dissolved in water;

[0058] At the same time, due to the movement of the sleeve 1003, the filter 1102 and the fixed frame 1101 are pulled to move through the cleaning rod 1006, so that the shaking spring 1104 is stretched, and when the rebound force of the stretched shaking spring 1104 is greater than the magnetic attraction between the magnetic ring 1205 and the magnetic ring 1005, the fixed frame 1101 and the filter 1102 will rebound under the action of the shaking spring 1104, and then the sleeve 1003 drives the spiral plate 1004 to move in the direction of the filter 1102 through the cleaning rod 1006, so that the filter 1102 and the spiral plate 1004 are shaken at the same time, so that the particles and droplets adhered to the outer surfaces of the filter 1102 and the spiral plate 1004 can be separated under the action of their own shaking, so that the filter 1102 and the spiral plate 1004 can absorb more particles and droplets, and the efficiency of smoke treatment is further improved;

[0059] The treated flue gas will enter the casing 2 and finally be discharged into the external environment through the exhaust pipe 4.

[0060] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
