Description

Technical Field

[0001] This invention relates to the field of dust removal technology in construction, specifically a dust removal device for construction. Background Technology

[0002] Construction site dust particles are small in size, highly dispersed, have a large relative surface area, are easily breathable, and have a wide diffusion range. Moreover, gas adsorption reduces the dust's wetting and coagulation properties. In addition, due to the influence of airflow and various agitations in the work environment, the dust will remain suspended in the air for a long time and spread everywhere, covering the construction site with a thick layer of dust, which will affect the health of the workers.

[0003] A typical dust removal device consists of components such as a spray chamber, a water pump, a water tank, and a fan. The water pump draws water from the water tank and pumps it into the spray chamber, where the water is atomized into a mist. The fan then blows the mist out of the spray chamber, causing dust in the surrounding environment to settle and thus achieving the dust removal effect.

[0004] Currently, most construction sites primarily use spraying to reduce airborne dust. This method involves the dust combining with the sprayed water mist and settling down. However, when the water evaporates, the dust floats back up, causing secondary pollution in the morning. This dust removal method is not ideal. Furthermore, existing sprayers have a limited spray range and cannot spray over large areas. They can only spray in a fixed direction, and adjusting the direction requires manual intervention. Because dust removal is limited to a fixed direction, the dust removal effect is poor. Moreover, multiple dust removal devices need to be used in conjunction on construction sites, significantly increasing dust removal costs. Therefore, this paper proposes a dust removal device for construction sites to address the above problems. Summary of the Invention

[0016] 1. This invention employs a dust extraction method to draw dust and impurities from the gas into a dust collector, allowing them to adhere and be filtered within the dust collector, thus preventing secondary pollution of the environment. Through the arrangement of a first bevel gear, a second bevel gear, a rotating shaft, and an air inlet pipe, the rotating shaft drives the first bevel gear, which in turn drives the meshing second bevel gear, which in turn drives the air inlet pipe.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-4 As shown, a dust removal device for construction includes a dust collection box 1; the dust collection box 1 is a hollow structure; a sealing cover 2 is provided at the upper end of the dust collection box 1; a motor 3 is fixedly connected to the upper end of the sealing cover 2; a rotating shaft 5 is fixedly connected to the output shaft of the motor 3; a transmission assembly 6 is fixedly connected to the rotating shaft 5; air inlet pipes 4 are symmetrically rotatably connected to both sides of the upper end of the dust collection box 1; a first mounting base 71 is fixedly connected to the lower outer wall of the dust collection box 1; an air pump 7 is fixedly connected to the first mounting base 71; the air inlet of the air pump 7 is connected to the dust collection box 1 through an air pipe.

[0027] During operation, motor 3 and vacuum pump 7 start. Vacuum pump 7 draws away the gas in dust collection box 1 to create negative pressure. External gas containing dust and impurities enters dust collection box 1 through air inlet pipe 4. Motor 3 rotates, driving shaft 5 to rotate. Shaft 5 drives transmission component 6 to rotate. Transmission component 6 drives air inlet pipe 4 to rotate, enabling air inlet pipe 4 to draw in gas containing dust and impurities from a wider range, thus improving the dust removal effect.

[0028] In one embodiment of the present invention, the transmission assembly 6 includes a first bevel gear 61 and a second bevel gear 62; the first bevel gear 61 is fixed to the upper end of the rotating shaft 5; two second bevel gears 62 are provided; another second bevel gear 62 is fixedly connected to the air intake pipe 4; the first bevel gear 61 meshes with the two second bevel gears 62.

[0029] When working, motor 3 starts, and the output shaft of motor 3 drives the rotating shaft 5 to rotate. The rotating shaft 5 drives the first bevel gear 61 to rotate. Since the second bevel gear 62 meshes with the first bevel gear 61, when the first bevel gear 61 rotates, the two second bevel gears 62 rotate in opposite directions. The rotation of the second bevel gear 62 causes the air intake pipe 4 to rotate, so that the air intake pipe 4 can draw in air from a larger range and improve the dust removal efficiency.

[0030] The air inlet of the air inlet pipe 4 is flared; a number of air holes 41 are equally spaced at one end of the air inlet pipe 4 located inside the dust collector 1; a bearing 8 is fixedly connected at the connection between the air inlet pipe 4 and the dust collector 1.

[0031] During operation, the horn-shaped air inlet can draw in more air. The gas containing dust and impurities is drawn into the air inlet pipe 4 through the air inlet and enters the dust collection box 1 through the air hole 41. The air entering the dust collection box 1 will be adsorbed on the inner wall of the dust collection box 1 after contacting it, achieving a preliminary dust removal effect. The bearing 8 makes the air inlet pipe 4 rotate more smoothly and reduces the resistance when the air inlet pipe 4 rotates.

[0032] A partition 9 is fixedly connected to the lower end of the interior of the dust collector 1; the partition 9 divides the dust collector 1 into upper and lower parts, and the dust collector 1 below the partition 9 is a water tank, the water level in the water tank being lower than the height of the air pipe connecting the air pump 7 and the dust collector 1; the partition 9 is cone-shaped; a connecting hole 91 is provided at the bottom of the partition 9.

[0033] During operation, water is injected into the water tank through the water inlet pipe (not shown). The water level should be lower than the height of the air pipe connecting the air pump 7 and the dust collector 1 to prevent the air pump 7 from drawing away the water. When the air pump 7 is pumping air, the air inlet pipe 4, the air hole 41, and the connecting hole 91 form a passage, allowing the gas with dust and impurities from the outside to enter the dust collector 1 smoothly. The clean gas after being cleaned by the dust collector 1 is then extracted from the dust collector 1, allowing the gas with dust and impurities to circulate smoothly and be cleaned in the dust collector 1. When the air with dust passes through the partition 9 and flows through the connecting hole 91, the flow space becomes smaller, causing the gas to come into contact with the upper surface of the partition 9. A large amount of dust is adsorbed and remains on the upper surface of the partition 9, further cleaning the gas with dust and impurities. When the water in the water tank needs to be replaced, the drain valve (not shown) can be opened to drain the water.

[0034] A first filter screen 11 is provided inside the connecting hole 91; the first filter screen 11 is detachably snapped onto the partition 9 and passes through the connecting hole 91;

[0035] During operation, gas containing dust and impurities enters through the inlet pipe 4 and comes into contact with the interior of the dust collector 1 and the partition 9, achieving a certain dust removal effect. When the gas passes through the connecting hole 91, some large particles or plastic sheets are intercepted by the first filter screen 11 and remain in the first filter screen 11. After the dust removal device has been working for a period of time, the sealing cover 2 is opened, the first filter screen 11 is taken out, the impurities in the first filter screen 11 are poured out, and then the first filter screen 11 is put back into the partition 9 and locked in place, so that the dust removal work can continue.

[0036] The dust collector 1 has several water outlet holes 10 at equal intervals at its upper end; an annular groove 101 is fixedly connected to the outside of the water outlet hole 10; the annular groove 101 communicates with the water outlet hole 10.

[0037] During operation, when gas containing dust and impurities enters the dust collector 1, a large amount of dust comes into contact with the inner wall of the dust collector 1 and the partition 9, and remains on the partition 9 and the inside of the dust collector 1. At this time, water is injected into the annular groove 101, and the water in the annular groove 101 is sprayed into the dust collector 1 through the water outlet 10. The sprayed water washes away the dust on the inner wall of the dust collector 1 and the partition 9, and flows along the inner wall of the dust collector 1 and the partition 9 through the first filter screen 11. The first filter screen 11 filters out the large particles in the impurities again, cleaning the dust on the inner wall of the dust collector 1 and the upper surface of the partition 9. At the same time, spraying water into the dust collector 1 also has the effect of dust removal and dust reduction, further removing and reducing dust from the gas containing dust and impurities.

[0038] The lower end of the dust collection box 1 is fixedly connected to a water pump 12 via a second mounting base 121; the outlet of the water pump 12 is fixedly connected to and communicates with the annular groove 101 via a connecting pipe 122, and the inlet of the water pump 12 is always kept below the horizontal plane of the water tank; a second filter screen 123 is fixedly connected to the inlet of the water pump 12.

[0039] During operation, the water pump 12 and motor 3 start simultaneously, or they can be started after dust removal begins. After the water pump 12 starts, the water in the water tank is drawn away by the water pump 12 through the second filter screen 123 and pumped into the annular groove 101 through the connecting pipe 122. It is then sprayed into the dust removal box 1 through the water outlet 10. After the water in the water tank is flushed and circulated through the inner wall and partition 9 of the dust removal box 1, some dust and impurities will remain. The second filter screen 123 filters the impurities in the water tank to obtain cleaner water, which makes it more effective when rinsing the inner wall and partition 9 of the dust removal box 1. After the water pump 12 has been working for a period of time, the second filter screen 123 is replaced, and the water pump 12 can continue to pump water for dust removal spraying.

[0040] A first scraper 13 and a second scraper 14 are fixedly connected to the rotating shaft 5; both the first scraper 13 and the second scraper 14 are provided with bristles; the first scraper 13 is in contact with the inner wall of the dust collection box 1; the second scraper 14 is in contact with the upper surface of the partition 9.

[0041] During operation, gas containing dust and impurities enters the dust collector 1 and flows through the partition 9 into the water tank via the connecting hole 91. The water in the tank then removes and reduces dust. This results in a large amount of dust adhering to the inner wall of the dust collector 1 and the upper surface of the partition 9. If not cleaned promptly, the connecting hole 91 will become clogged, hindering gas circulation. Therefore, during dust removal, the motor 3 rotates, driving the rotating shaft 5 to rotate. The rotating shaft 5 drives the first scraper 13 and the second scraper 14 to rotate. The bristles on the first scraper 13 brush against the dust collector... The inner wall of the dust collector 1 is rotated and cleaned, and the bristles on the second scraper 14 clean the upper surface of the partition 9. At the same time, the water pump 12 continuously pumps water out of the water tank and sprays it into the dust collector 1. The sprayed water can not only soften the dust on the inner wall of the dust collector 1 and the upper surface of the partition 9, making it easier for the first scraper 13 and the second scraper 14 to clean, but also wash away the dust cleaned by the first scraper 13 and the second scraper 14, and flush the dust into the first filter screen 11 for thorough filtration and cleaning.

[0042] The air inlet pipe 4 is fixedly connected to a cleaning assembly 15 at one end inside the dust collector 1; two cleaning assemblies 15 are provided; the two cleaning assemblies 15 are arranged symmetrically; each cleaning assembly 15 includes a fixing frame 151; the fixing frame 151 consists of a horizontal plate and two columns; a guide tube 152 is fixedly connected to the horizontal plate; two guide tubes 152 are provided; the guide tubes 152 are used to position the brush rod 153; the brush rod 153 is slidably connected inside the guide tube 152; a spring 154 is fixedly connected to one end of the brush rod 153; the other end of the spring 154 is fixedly connected to the horizontal plate, and the moving direction of the brush rod 153 points towards the air hole 41; the diameter of the brush rod 153 is smaller than the diameter of the air hole 41; a triangular baffle 155 is fixedly connected to the dust collector 1; the triangular baffle 155 is located on one side of the cleaning assembly 15 and is at the same height as the horizontal direction of the fixing frame 151.

[0043] During operation, initially, the brush rod 153 separates from the air hole 41 under the action of the spring, allowing the air hole 41 to draw in air normally. During the dust removal process, because the air inlet pipe 4 is constantly rotating, it draws in dusty gas from the outside into the dust collection box 1. As this gas flows through the air hole 41, dust adheres to the inner wall of the air hole 41. If it is not cleaned in time, the air hole 41 will be blocked by this dust, resulting in a decrease in the air intake efficiency of the air inlet pipe 4. Therefore, a cleaning component 15 is set up to clean the dust from the air hole 41. The triangular baffle 155 is fixed to one side of the brush rod 153. When the air pipe 4 rotates, it will drive the cleaning component 15 to clean the dust from the air hole 41. When the components 15 rotate together, when the brush rod 153 rotates to the triangular baffle 155, the brush rod 153 will move on the inclined surface of the triangular baffle 155, so that the brush rod 153 is squeezed by the triangular baffle 153, causing the brush rod 153 to move towards the air hole 41 to clean the inner wall of the air hole 41. At the same time, the movement of the brush rod 153 will squeeze the spring 154, and the air tube 4 will continue to rotate, causing the brush rod 153 to disengage from the triangular baffle 155. The spring 154 will return and push the brush rod 153 to reset. When the cleaning component 15 on the other side rotates to the triangular baffle 155, the same thing happens, thereby achieving the cleaning of the air hole 41.

[0044] Working principle: Start motor 3, air pump 7, and water pump 12; after air pump 7 starts working, it draws away the gas inside dust collector 1 to create negative pressure. The air inlet pipe 4, air hole 41, and connecting hole 91 form a passage, allowing gas containing dust and impurities to enter through air inlet pipe 4. The gas containing dust and impurities passes through the inner wall of dust collector 1, partition 9, first filter screen 11, and water in the water tank, and is then discharged through air pump 7. At the same time, the gas passing through water becomes more humid. After being discharged, it can remove dust from the outside air. Motor 3 works, causing shaft 5 to rotate. The first bevel gear 61 and the second bevel gear 62 are driven to rotate, causing the air intake pipe 4 to rotate. The air intake pipe 4 can draw in gas from a wider range. A large amount of gas containing dust and impurities adheres to the inner wall of the dust collector 1 and the partition 9. The water pump 12 draws water from the water tank and sprays the water into the dust collector 1 through the annular groove 101 and the water outlet 10. At the same time, the rotating shaft 5 rotates to make the first scraper 13 and the second scraper 14 rotate, cleaning the inner wall of the dust collector 1 and the upper surface of the partition 9, thereby achieving the cleaning and rinsing of the inner wall of the dust collector 1 and the partition 9.
