Description

Technical Field

[0001] The present invention relates to the technical field of building engineering, and in particular to dust reduction equipment for building engineering construction. Background Art

[0002] A lot of dust is generated during construction projects, especially when the hammer machine breaks cement and concrete. The powder in the building materials can easily spread together with the sand and soil on the construction site.

[0003] In the prior art, a fog cannon truck is usually installed near the construction site, and the fog cannon truck is aimed at the dust-raising area for dust reduction. However, when there is wind in the construction environment, the water mist sprayed by the fog cannon truck is easily blown away by the wind, and the dust in the dust-raising area cannot be effectively reduced. At this time, the fog cannon truck needs to be moved to the upwind position of the dust-raising area. However, in this case, the water mist of the fog cannon truck is easily blown onto the glass of the construction machinery cab, affecting the field of vision of the construction machinery operator and having an adverse effect on construction safety. In addition, in strong wind weather, the water mist of the fog cannon truck diffuses very quickly and will be blown away when it cannot come into contact with the dust. At this time, the fog cannon truck cannot achieve the effect of dust reduction and cannot meet the environmental protection requirements during construction. In addition, the fog cannon truck needs to increase the water output in windy weather to increase the coverage area of ​​the water mist.

Compared with the existing dust reduction of fog cannon trucks, the dust can be accurately reduced at the construction location, and the problem that the water mist sprayed by the fog cannon truck is easily blown away by the wind in windy weather, thereby failing to achieve a good dust reduction effect; By setting the filter disc, the water with dust is pumped away by the water pump through the drain pipe and the telescopic pipe, and then the water with dust is pumped into the water tank by the water pump, so that the water with dust flows through the filter disc, so that the dust in the water is filtered out by the filter disc, and the water separated from the dust enters the water tank and continues to be used for dust reduction.

Compared with the dust reduction of the fog cannon barrel, part of the water can be recycled to achieve the effect of saving water, which is more environmentally friendly. At the same time, it can also reduce the frequency of adding water to the water tank, making it more convenient to use. Through the cooperation of the push pin and the chute, the eight nozzles surrounding the dust collection tank spray water to the position of the hammer head at the same time, so as to achieve the effect of dust reduction on the outside of the dust generation place, cooperate with the dust collection tank to suck dust, prevent dust from spreading around the construction site, and improve the dust reduction effect. At the same time, the water sprayed by the nozzle falls on the hammer head, which can dissipate the heat of the hammer head generated during construction, which helps to extend the service life of the hammer head. When the push pin rotates and enters the chute, the rotating wheel will rotate under the action of the push pin in the chute, and the gear drives the rack to slide away from the fixed disk, so that the rack pushes the nozzle away from the dust collection tank through the connecting rod. The eight nozzles are synchronously away from the dust collection tank, thereby achieving the effect of expanding the spraying range of the nozzle to cope with the environment that is more prone to dust during construction. Through the cooperation of the dial groove and the dial shaft, after the electromagnet is started, the turntable two drives the orifice plate two to rotate slightly twice, and the water pressure when the water flows through is adjusted under the action of the two sets of hole positions. When the orifice plate one and the orifice plate two are completely aligned, the water flow through the disc one and the disc two is not hindered, so there is a strong water pressure, so as to increase the intensity of the water sprayed by the nozzle, thereby avoiding the water spray being blown away by the strong wind in windy weather, and achieving the effect of coping with bad weather.

[0023] Further, such as Figure 1 , Fig.11 , Fig.12As shown, a water circulation component is arranged on the top of the hammer machine body 1, and the water circulation component includes a water tank 601 fixedly installed on the top of the hammer machine body 1, a box cover 602 is threadedly connected to the top of the water tank 601, a water pump 1 603 is fixedly installed on the top of the box cover 602, a telescopic tube 1 604 is fixedly connected to the output port of the water pump 1 603, a water pump 2 605 is fixedly installed on the top of the box cover 602, a telescopic tube 2 606 is fixedly connected to the output port of the water pump 2 605, a circular groove 607 is opened on the top of the water tank 601, a filter screen plate 608 is sleeved in the circular groove 607, a water inlet end of the water pump 2 605 passes through the filter screen plate 608, an end of the telescopic tube 1 604 away from the water pump 1 603 is fixedly connected to the drain pipe 508, and an end of the telescopic tube 2 606 away from the water pump 2 605 is fixedly connected to the water inlet pipe 507.

[0024] In combination with the above embodiments, the entire working process and working principle of the above embodiments are as follows: The initial state is: The motor 311 is not energized, the rack 309 is close to the air inlet pipe 503, the nozzle 314 is close to the surface of the dust collector 2, the electromagnet 412 is not energized, the moving iron core 410 is located on the side of the slide groove 409 close to the orifice plate 1 405, the holes of the orifice plate 1 405 and the orifice plate 2 407 are not aligned, the fan 506 is not started, the water pump 1 603 and the water pump 2 605 are not energized, the water tank 601 is full of water, the tank cover 602 is installed on the water tank 601, the output end of the water pump 2 605 is below the water surface in the water tank 601, and the filter plate 608 is located in the circular groove 607.

[0025] The working status is: Collecting dust during construction: When construction begins, start the fan 506, water pump one 603 and water pump two 605, so that the fan 506 draws out the air inside the dust collection tank 2, so that the dust generated during the construction of the hammer machine body 1 is sucked in from the bottom of the dust collection tank 2. At this time, the water pump two 605 transports the water inside the water tank 601 to the fixed plate 504 through the telescopic tube two 606 and the water inlet pipe 507, so that a circle of atomizing nozzles 505 sprays the dust entering the dust collection tank 2, and the dust absorbs the water mist, so that the dust falls into the collecting tube 502 under the action of water, and the air without dust is drawn out by the fan 506, so as to achieve the effect of circulating dust removal of the air generated during construction. Compared with the existing dust reduction of fog cannon vehicles, it can accurately reduce dust at the construction location to prevent the water mist sprayed by the fog cannon vehicle from being easily blown away by the wind in windy weather, thereby failing to achieve a better dust reduction effect.

[0026] Recycling water: When part of the water sprayed by the atomizing nozzle 505 absorbs the dust and falls into the collecting tube 502, the water sprayed by the atomizing nozzle 505 also falls into the collecting tube 502, so that the water with dust is pumped away by the water pump 603 through the drain pipe 508 and the telescopic tube 604, and then the water with dust is pumped into the water tank 601 by the water pump 603, so that the water with dust flows through the filter plate 608, so that the dust in the water is filtered out by the filter plate 608, and the water separated from the dust enters the water tank 601 and continues to be used for dust reduction. After use, the box cover 602 can be unscrewed, so that the filter plate 608 can be pulled up and taken out from the circular groove 607, and the dust collected in the filter plate 608 can be cleaned to prevent the filter plate 608 from being blocked. Compared with the dust reduction of the fog cannon barrel, part of the water can be recycled to achieve the effect of saving water, which is more environmentally friendly. At the same time, the frequency of adding water to the water tank 601 can also be reduced, making it more convenient to use.

[0027] Dust reduction at the construction site: When the fan 506 is started to make the dust collector 2 suck in the dust, the water sent into the fixed disk 504 by the water pump 2 605 enters the bellows expansion tube 404 through the water pipe buried in the dust collector 2, so that the water passes through the connecting head 403, the second disk 402 and the first disk 401 in turn and is sprayed out from the nozzle 314. At this time, the eight nozzles 314 surrounding the dust collector 2 simultaneously spray water to the position where the hammer head is located, thereby achieving the effect of dust reduction on the outside of the dust generation site, cooperating with the dust suction of the dust collector 2 to prevent the dust from spreading around the construction site, thereby improving the dust reduction effect. At the same time, the water sprinkled by the nozzle 314 falls on the hammer head, which can dissipate the heat of the hammer head during construction, which helps to extend the service life of the hammer head.

[0028] Adjust the spraying range: When there is sand and stone powder in the construction environment, dust is more likely to be raised, and thus diffused into the surrounding environment before contacting the water mist sprayed by the fog cannon vehicle. At this time, the motor 311 is started, so that the motor 311 drives the gear 2 312 to rotate, so that the gear 2 312 drives the turntable 1 302 to rotate through the dial plate 303, and the turntable 1 302 drives the pin 304 on its top to rotate, so that the pin 304 enters the inclined slot 307, and under the action of the inclined slot 307 being opened obliquely, after the pin 304 rotates and enters the inclined slot 307, the wheel 306 will The inclined groove 307 rotates under the action of the pin 304, so that the wheel 306 drives the gear 308 to rotate, and then the gear 308 drives the rack 309 to slide away from the fixed disk 504, so that the rack 309 pushes the nozzle 314 away from the dust collection tank 2 through the connecting rod 313. The rotation of the turntable 1 302 simultaneously drives the eight wheels 306 to rotate, so that the eight nozzles 314 are synchronously away from the dust collection tank 2, thereby achieving the effect of expanding the spraying range of the nozzle 314 to cope with the environment where dust is more easily generated during construction.

[0029] Adjust the spray pressure: In windy weather, the water mist sprayed by the fog cannon truck is easily blown away by the wind, and it is impossible to effectively reduce the dust raised in the construction site. In addition, the water mist and dust are easily blown onto the cab glass of the hammer machine body 1, affecting the workers' field of vision and causing adverse effects on construction safety. At this time, the electromagnet 412 is started, so that the electromagnet 412 has an adsorption effect on the moving iron core 410, so that the moving iron core 410 drives the dial shaft 411 to slide toward the side close to the electromagnet 412 while squeezing the reset spring 413. When the moving iron core 410 slides toward the side close to the electromagnet 412, the dial shaft 411 slides toward the top of the V-shape of the dial groove 408 in cooperation with the dial groove 408, thereby turning the turntable 2 406, so that the turntable 2 406 drives the orifice plate 2 407 to rotate. After the electromagnet 412 is powered off, the moving iron core 410 is reset under the action of the extension of the reset spring 413, so that the dial shaft 411 is reset and cooperates with the V-shaped groove of the dial groove 408 again, sliding to the connection between the two adjacent V-shaped grooves, so that the turntable 406 drives the orifice plate 407 to rotate slightly again. At this time, the turntable 406 drives the orifice plate 407 to rotate slightly twice, and the water pressure when the water flows through is adjusted under the action of the two groups of hole positions. When the orifice plate 1 405 and the orifice plate 2 407 are completely aligned, the water flow through the disc 1 401 and the disc 2 402 is not hindered, so as to have a strong water pressure, so as to increase the intensity of the water sprayed by the sprinkler 314, thereby preventing the water spray from being blown away by the strong wind in windy weather, and achieving the effect of coping with bad weather.

[0030] The above descriptions are merely embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
