Description

Technical Field

[0001] The invention relates to the technical field of dustproof cleaning, and in particular to a dustproof cleaning device at an engineering project site. Background Art

[0002] Since construction projects are generally developed on wasteland, and since a large amount of sand and stone is needed in the project, at the construction project site, when workers and vehicles pass by, large amounts of dust are often raised. The dust fills the air, which not only obstructs the line of sight and makes it impossible for workers to observe the situation in time, but also affects the workers' bodies when the raised dust is inhaled into their bodies. Excessive inhalation of dust can cause pharyngitis, emphysema, asthma, rhinitis, bronchitis and other inflammations. Long-term inhalation of dust may also cause some irreversible damage to the body and cause permanent physical losses to the construction workers. Therefore, dust control at the project site is an important safety measure during construction. At the project site, a dust-proof cleaning device is usually set up at a certain distance to ensure a good environment on site.

[0003] In the prior art, dust-proof cleaning devices generally use atomized water spraying to reduce dust. This method not only causes a large amount of water to accumulate on the road surface, which mixes with the soil on the road surface to form mud, making the on-site environment worse, but also consumes a large amount of water resources, resulting in a waste of water resources. Summary of the invention

[0008] Furthermore, the control component also includes an electromagnet, which is fixedly connected to the inner wall of one of the side cavities, a light strip is fixedly embedded in the inner top wall of the airway, and a plurality of photoresistors are fixedly embedded in the inner bottom wall of the airway. The photoresistors are electrically connected to the electromagnets through wires, one end of the sliding rod extends through one of the side cavities, and the other end extends through the outside of the shell, and both ends of the sliding rod are fixedly connected to a fixed disk, a spring is fixedly connected between the fixed disk outside the shell and the shell, and the first pulley is rotatably connected to the side wall of the fixed disk inside the shell through a bearing.

[0009] Furthermore, the dust reduction component also includes an insertion hole, which is opened on the side wall of the shell. The insertion hole connects the water cavity with the outside world. The shell is slidably connected to a mesh frame through the insertion hole, and the inner wall of the mesh frame is fixedly connected to a filter.

[0010] Furthermore, the cleaning mechanism also includes a plurality of third pulleys, the third pulleys correspond to the rotating rods one by one, the third pulleys are fixedly connected with the corresponding rotating rods, the third pulleys are jointly cooperated with a second synchronous belt, the rotating rods are fixedly connected with a cleaning roller, one of the rotating rods extends into one of the side cavities and is fixedly connected with the second pulley, and the second pulley and the first pulley are jointly cooperated with a first synchronous belt.

[0014] Furthermore, a plurality of guide rods are fixedly connected between the inner top wall and the inner bottom wall of the side cavity, and the guide rods are slidably connected with the corresponding tooth frames.

[0015] The present invention has the following advantages: 1. The external air is sucked into the shell, and the dust is sprayed in the dust reduction chamber inside the shell, instead of spraying water directly to the outside as in the prior art, so as to avoid the accumulation of spray water on the ground, which will lead to the deterioration of the on-site environment; 2. The inside of the shell is sprayed to reduce dust. The sprayed water is accumulated on the filter and filtered through the filter. The filtered water is sucked in and then pumped out for dust reduction. Thus, while reducing dust, the recycling of water resources is achieved, avoiding the waste of water resources caused by direct spraying as in the prior art. 3. After the air is sucked into the airway, the light strip emits light and shines on the photoresistor. If there is a lot of dust in the air, most of the light will be blocked, which will reduce the light on the photoresistor and increase the resistance. Otherwise, the resistance will decrease. The change in the resistance of the photoresistor will change the resistance of the shaft rotation, thereby controlling the air intake speed, so that the device can automatically adjust the processing efficiency according to the size of the dust, greatly improving the degree of automation of the device; 4. The rotation of the gear drives the first pulley to rotate through friction, and the first pulley drives the second pulley through the transmission of the first synchronous belt, and then the third pulley and the second synchronous belt drive all the cleaning rollers to rotate synchronously, sweeping the blocked materials on the filter into the storage tank. While dust is falling, the filter is automatically cleaned without frequent manual cleaning, which greatly reduces labor intensity and improves dust reduction efficiency; 5. When the dust is heavy, the filter cleaning efficiency is reduced and the dust reduction efficiency is improved. When the dust is light, the dust reduction efficiency is reduced and the filter cleaning efficiency is improved. While ensuring the cleaning ability, the energy of the air pump is reasonably utilized, avoiding the energy waste caused by controlling the shaft speed, making the device more energy-efficient. 6. The slider is driven by air to reciprocate up and down to spray water, that is, the water spraying speed is related to the air speed. While controlling the air intake speed by sensing the amount of dust, the water pumping speed can also be notified synchronously, further improving the degree of automation of the device.

DETAILED DESCRIPTION

[0018] Reference Figure 1-9 , a dust-proof cleaning device for a construction project site, comprising a shell 1, a side wall of the shell 1 is fixedly connected to an air pump 2 through a bracket, an input pipe of the air pump 2 is fixedly connected to the shell 1, and a filter component is arranged in the air pump 2 to prevent dust from entering the air pump 2 and affecting the normal operation of the air pump 2; A cleaning mechanism is arranged in the shell 1, and the cleaning mechanism is composed of an airflow component, a dust reduction component and a control component. The airflow component includes an airway 4 and a dust reduction chamber 3. The dust reduction chamber 3 is arranged in the shell 1, and the airway 4 connects the dust reduction chamber 3 with the outside. The input pipe of the air pump 2 extends through and into the dust reduction chamber 3. The shell 1 is rotatably connected with a rotating shaft 6 through a bearing. The dust reduction component includes two side chambers 8 and a water chamber 25. The side chamber 8 and the water chamber 25 are both arranged in the shell 1, and the side chamber 8 is symmetrically arranged about the water chamber 25. Both ends of the rotating shaft 6 extend through and into the corresponding side chambers 8 and are fixedly connected with gears 9. The control component includes a plurality of sliding rods 10, and the sliding rods 10 are slidably connected with the shell 1. A first pulley 12 is slidably connected to the side wall of one of the gears 9, and a rubber pad is glued to the side wall on the side where the gear 9 contacts the first pulley 12 to increase the friction between the two, so that the rotation resistance of the rotating shaft 6 can be better controlled by friction. A cleaning mechanism is disposed in the housing 1 , and the cleaning mechanism includes a plurality of rotating rods 31 . The rotating rods 31 are rotatably connected to the housing 1 via bearings.

[0019] The airflow component also includes a groove 5, which is opened on the top wall of the airway 4. The shaft 6 passes through the groove 5. The side wall of the shaft 6 located in the groove 5 is fixedly connected with a plurality of blades 7 (such as Figure 2 As shown in the figure, when the air in the air duct 4 passes through, it will impact the blades 7, so that the blades 7 drive the shaft 6 to rotate. The magnitude of the resistance to the rotation of the shaft 6 determines the resistance to the passage of the air, thereby determining the air flow speed.

[0020] The dust suppression assembly also includes two sliding sleeves 19, which are fixedly connected to the inner bottom wall of the corresponding side cavity 8, and a slider 20 is sealed and slidably connected in the sliding sleeve 19. A plurality of connecting rods 21 are fixedly connected to the upper surface of the slider 20, and a tooth frame 17 is fixedly connected to the upper surface of the connecting rod 21. The tooth frame 17 is meshed with the corresponding gear 9, and the two opposite inner side walls of the tooth frame 17 are provided with teeth (such as Figure 7 and Figure 8 As shown), the gear 9 is an incomplete gear. During the rotation process, the gear 9 will alternately mesh with the two sets of teeth of the gear frame 17, so that the gear frame 17 reciprocates up and down. The housing 1 and the sleeve 19 are jointly penetrated and fixedly connected with a plurality of pump outlet pipes 22 and a suction pipe 29. One end of the pump outlet pipe 22 extends through the corresponding sleeve 19, and the other end extends through the dust reduction chamber 3. One end of the pump outlet pipe 22 located in the dust reduction chamber 3 is jointly penetrated and fixedly connected with a top block 23. The top block 23 is a hollow structure. The bottom wall of the top block 23 is penetrated and fixedly connected with a plurality of atomizing nozzles 24. One end of the suction pipe 29 extends through the corresponding sleeve 19, and the other end extends through the water cavity 25. The suction pipe 29 extends to the bottom of the water cavity 25 (as shown in FIG. Figure 5As shown), water is absorbed from the bottom of the water chamber 25 to avoid absorbing dust floating on the water surface of the water chamber 25, which affects the dust reduction effect. When air is sucked in through the air duct 4, the air impacts the blade 7, so that the blade 7 drives the shaft 6 to rotate, and the rotation of the shaft 6 drives the gear 9 to rotate. The rotation of the gear 9 will alternately mesh with the teeth on both sides of the gear frame 17, so that the gear 9 drives the gear frame 17 to reciprocate up and down during the rotation process, and the gear frame 17 drives the slider 20 to reciprocate up and down through the connecting rod 21. When the slider 20 moves upward, The suction pipe 29 sucks the water in the water chamber 25 into the sliding sleeve 19, and then the slider 20 moves downward to pump the sucked water into the top block 23 through the pump outlet pipe 22, and then spray it out through the atomizing nozzle 24 to spray and reduce dust on the air containing dust entering the dust reduction chamber 3. After the dust-reduced air enters the air pump 2, it is discharged through the discharge pipe of the air pump 2. The internal spray dust reduction method avoids the adverse on-site environment caused by direct spraying of water. At the same time, the internal spray dust reduction method can also circulate water to avoid the waste of water resources caused by direct spraying.

[0021] Reference Figure 7-9 It is worth mentioning that the positions of the two gears 9 are symmetrical, so that the two gears 9 are respectively meshed with the teeth on different sides of the corresponding tooth frame 17, so that the two tooth frames 17 always keep reciprocating in different directions, so that there is always a slider 20 pumping water into the top block 23, ensuring that during the dust reduction period, the atomizing nozzle 24 always keeps spraying water mist, avoiding sewage pumping out when the two sliders 20 are in the water absorption stage at the same time, affecting the dust reduction effect.

[0022] The control component also includes an electromagnet 14, which is fixedly connected to the inner wall of one of the side cavities 8. A light strip 15 is fixedly embedded in the top wall of the airway 4, and a plurality of photoresistors 16 are fixedly embedded in the bottom wall of the airway 4. The photoresistor 16 is a semiconductor element based on the internal photoelectric effect. Its resistance value depends on the change of the incident light intensity. When the incident light intensity increases, the resistance value of the photoresistor 16 decreases. When the incident light weakens, the resistance value of the photoresistor 16 increases. This is a prior art and will not be described in detail here. The photoresistor 16 is electrically connected to the electromagnet 14 through a wire. One end of the slide bar 10 extends through one of the side cavities 8, and the other end extends through the slide bar 10. The slide rod 10 extends to the outside of the shell 1, and a fixed plate 11 is fixedly connected to both ends of the slide rod 10. It should be noted that the fixed plate 11 located inside the shell 1 is made of ferromagnetic material, which can be affected by the magnetic repulsion of the electromagnet 14, and the fixed plate 11 located outside the shell 1 is made of aluminum alloy, which is not affected by the magnetic force of the electromagnet 14. A spring 13 is fixedly connected between the fixed plate 11 located outside the shell 1 and the shell 1. The spring 13 is also made of aluminum alloy and is not affected by the magnetic force of the electromagnet 14. The first pulley 12 is rotatably connected to the side wall of the fixed plate 11 located inside the shell 1 through a bearing. After the air enters the airway 4, the light The light strip 15 emits light and passes through the inhaled air. When there is a lot of dust in the air, the light emitted by the light strip 15 is mostly blocked due to the obstruction of the dust and cannot be irradiated on the photoresistor 16, thereby reducing the intensity of the incident light on the photoresistor 16 and increasing the resistance of the photoresistor 16. The increase in the resistance of the photoresistor 16 will reduce the voltage across the electromagnet 14, thereby reducing the magnetic repulsion of the electromagnet 14 on the fixed disk 11. Under the elastic force of the spring 13, the pressure of the first pulley 12 on the gear 9 is reduced, thereby reducing the friction resistance between the two. The reduced friction resistance makes the shaft 6 rotate faster. The resistance is reduced, and the resistance of the air to push the blade 7 to move is also reduced accordingly, so that the kinetic energy lost by the air through the blade 7 is less, thereby increasing the suction and exhaust speed. On the contrary, when there is less dust in the air, the incident light intensity of the photoresistor 16 increases, the resistance value decreases, and the magnetic repulsion of the electromagnet 14 on the fixed disk 11 increases, thereby increasing the friction resistance between the first pulley 12 and the gear 9, and the resistance to the rotation of the shaft 6 increases, reducing the suction and exhaust speed, so that the device can automatically adjust the dust reduction speed according to the amount of dust in the air, thereby greatly improving the degree of automation of the device.

[0023] The dust suppression assembly also includes an insertion hole 26, which is opened on the side wall of the shell 1. The insertion hole 26 connects the water cavity 25 with the outside. The shell 1 is slidably connected with a mesh frame 27 through the insertion hole 26. The inner wall of the water cavity 25 is also provided with a protrusion (such as Figure 2As shown), it is used to carry the mesh frame 27, and the inner wall of the mesh frame 27 is fixedly connected with a filter 28. The water after spraying and dust reduction falls from the dust reduction chamber 3 into the water chamber 25 and falls on the filter 28. The filter 28 filters the water after spraying and dust reduction. The dust is blocked on the filter 28, and the water falls below and waits to be sucked in and pumped out again. The water after spraying and dust reduction is filtered to ensure that it can be recycled.

[0024] The cleaning mechanism also includes a plurality of third pulleys 34, which correspond to the rotating rods 31 one by one. The third pulleys 34 are fixedly connected to the corresponding rotating rods 31 through penetration, and the third pulleys 34 are jointly matched with a second synchronous belt 35. A cleaning roller 36 is fixedly connected to the rotating rod 31 through penetration, and a brush (not shown in the figure) is arranged on the side wall of the cleaning roller 36, which can sweep the material blocked on the surface of the filter screen 28 in one direction. One of the rotating rods 31 penetrates and extends into one of the side cavities 8 and is fixedly connected to the second pulley 32 through penetration, and the second pulley 32 and the first pulley 12 are jointly matched with a first synchronous belt 33. The outer walls of the first pulley 12, the second pulley 32, and the third pulley 34 are all provided with teeth (not shown in the figure), and the inner walls of the first synchronous belt 33 and the second synchronous belt 35 are both provided with teeth (not shown in the figure), so that the first pulley 12, the second pulley 32 and the first synchronous belt 33 and the third belt The wheels 34 and the second synchronous belt 35 are all meshingly driven to ensure smooth transmission. At the same time, it ensures that multiple horizontally arranged third pulleys 34 can be driven by the second synchronous belt 35 to rotate synchronously. During the rotation of the gear 9, the first pulley 12 is also driven to rotate by friction. The first pulley 12 drives the second pulley 32 to rotate through the first synchronous belt 33. The second pulley 32 drives one of the rotating rods 31 to rotate. The rotating rod 31 is driven by the third pulley 34 and the second synchronous belt 35, so that all the rotating rods 31 rotate synchronously, thereby making all the cleaning rollers 36 rotate synchronously. Through the rotation of the cleaning rollers 36, the dust on the surface of the filter 28 is swept toward the storage tank 30 until it is swept into the storage tank 30 for storage. While reducing dust, the filter 28 is self-cleaned to increase its service life. At the same time, frequent manual cleaning is avoided, greatly reducing labor intensity.

[0025] The screen frame 27 is provided with a storage groove 30, and the depth of the storage groove 30 gradually increases from the direction close to the rotating rod 31 to the direction away from the rotating rod 31 (e.g. Figure 2 As shown), by setting the storage groove 30, the dust cleaned by the cleaning roller 36 can slide into the storage groove 30 for storage, so as to facilitate subsequent unified processing.

[0026] Both the pump outlet pipe 22 and the suction pipe 29 are provided with a one-way valve. The one-way valve in the pump outlet pipe 22 only allows water to be pumped from the sliding sleeve 19 into the top block 23 , and the one-way valve in the suction pipe 29 only allows water to enter the sliding sleeve 19 from the water cavity 25 .

[0027] A dust hood 37 is fixedly connected to the side wall of the shell 1 , and the dust hood 37 is communicated with the air duct 4 . Through the arrangement of the dust hood 37 , the device can better suck air into the shell 1 .

[0028] A plurality of guide rods 18 are fixedly connected between the inner top wall and the inner bottom wall of the side cavity 8. The guide rods 18 are slidably connected to the corresponding tooth frames 17. Through the arrangement of the guide rods 18, the tooth frames 17 can reciprocate up and down more stably, thereby ensuring the smooth operation of the device.

[0029] In the present invention, when the device is used, a certain amount of water is injected into the water cavity 25 through the water pipe so that the water surface is located a certain distance below the filter 28, and then the air pump 2 is turned on to inhale air, so that the external air is sucked into the air duct 4 through the dust collecting hood 37.

[0030] When air is inhaled through the air passage 4, the air impacts the blades 7, causing the blades 7 to drive the rotating shaft 6 to rotate. The rotation of the rotating shaft 6 will drive the gear 9 to rotate. The rotation of the gear 9 will alternately mesh with the teeth on both sides of the gear frame 17, so that the gear 9 drives the gear frame 17 to reciprocate up and down during the rotation process. The gear frame 17 drives the slider 20 to reciprocate up and down through the connecting rod 21. When the slider 20 moves upward, the water in the water cavity 25 is sucked into the sliding sleeve 19 through the suction pipe 29, and then the slider 20 moves downward, and the inhaled water is pumped into the top block 23 through the pump outlet pipe 22, and then atomized and sprayed out through the atomizing nozzle 24, so as to spray and reduce dust on the air containing dust entering the dust reduction chamber 3. After the dust-reduced air enters the air pump 2, it is discharged through the discharge pipe of the air pump 2.

[0031] After the air enters the airway 4, the light strip 15 emits light and passes through the inhaled air. When there is a lot of dust in the air, the light emitted by the light strip 15 is mostly blocked due to the obstruction of the dust and cannot be irradiated on the photoresistor 16, thereby reducing the incident light intensity of the photoresistor 16 and increasing the resistance of the photoresistor 16. The increase in the resistance of the photoresistor 16 will reduce the voltage across the electromagnet 14, thereby reducing the magnetic repulsion of the electromagnet 14 on the fixed disk 11. Under the elastic force of the spring 13, the pressure of the first pulley 12 on the gear 9 is reduced, thereby causing The frictional resistance between the two is reduced, and the reduced frictional resistance reduces the resistance to the rotation of the shaft 6. At this time, the resistance of the air pushing the blade 7 to move is also reduced accordingly, so that the kinetic energy lost by the air through the blade 7 is less, thereby increasing the intake and exhaust speeds. Conversely, when there is less dust in the air, the incident light intensity of the photoresistor 16 increases, the resistance value decreases, and the magnetic repulsion of the electromagnet 14 on the fixed disk 11 increases, thereby increasing the frictional resistance between the first pulley 12 and the gear 9, and the resistance to the rotation of the shaft 6 increases, thereby reducing the intake and exhaust speeds.

[0032] The water after the spraying dust reduction falls from the dust reduction chamber 3 into the water chamber 25 and falls on the filter 28. The filter 28 filters the water after the spraying dust reduction. The dust is blocked on the filter 28, and the water falls below, waiting to be sucked in and pumped out again.

[0033] During the rotation of the gear 9, the friction force will also drive the first pulley 12 to rotate, and the first pulley 12 will drive the second pulley 32 to rotate through the first synchronous belt 33, and the second pulley 32 will drive one of the rotating rods 31 to rotate. The rotating rod 31 is driven by the third pulley 34 and the second synchronous belt 35, so that all the rotating rods 31 rotate synchronously, thereby making all the cleaning rollers 36 rotate synchronously, and through the rotation of the cleaning rollers 36, the dust on the surface of the filter 28 is swept toward the storage tank 30 until it is swept into the storage tank 30 for storage.

[0034] After using for a certain period of time, pull out the screen frame 27, clean the dust accumulated in the storage tank 30, clean the surface of the filter screen 28, pump out the water in the water cavity 25 through the water pipe, inject new water, and insert the screen frame 27 before using it again.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
