Description

Technical Field

[0001] The invention relates to the field of air purification, and in particular to an air purification device for building construction. Background Art

[0002] Construction refers to the process of turning various lines on the design drawings into physical objects at designated locations. Construction involves the processing and combination of various materials, including the construction of slate materials, wall coatings and other materials.

[0003] At present, a large amount of dust is generated during construction, which pollutes the air and easily causes harm to on-site construction workers. It is also troublesome to clean. Therefore, air purifiers are used at construction sites to clean dust, thereby purifying the air and reducing harm to the human body.

[0004] The existing equipment for protecting air in construction has the following disadvantages during its use: since a lot of dust is generated during construction and flies everywhere, when water mist is used to purify the dust, if the nozzle is installed upward, since the water droplets have a certain weight, not only the spraying height is not enough, but also the spraying area is narrow; if the nozzle is installed horizontally, the air at a high place cannot be dust-removed and purified, which has limitations during use and is inconvenient to use. Summary of the invention

[0005] The main purpose of the present invention is to provide an air purification device for building construction with a larger spraying area.

[0006] In order to achieve the above-mentioned main purpose, the air purification device for construction provided by the present invention includes a water tank, a spray assembly and a dust collection assembly; the spray assembly includes a water pump, a first water pipe and a second water pipe, the water pump is connected to the second water pipe and the water tank respectively through the first water pipe, the water pump and the second water pipe are respectively arranged on the top of the water tank, the second water pipe is arranged around the circumference of the water tank, and a plurality of spray heads are arranged at one end of the second water pipe away from the water tank; the dust collection assembly includes an air inlet wide-mouth frame, a fan, a first air duct and a second air duct, the fan is connected to the air inlet wide-mouth frame and the second air duct respectively through the first air duct, the air inlet wide-mouth frame is located at the top of the water tank, the second air duct is arranged around the circumference of the water tank, a plurality of air nozzles are arranged at one end of the second air duct away from the water tank, the second air duct is located on the lower side of the second water pipe, and the spray head is arranged toward the air nozzle or installed horizontally.

[0007] It can be seen from the above scheme that the water pump draws out the water in the water tank and sprays it out from the spray head through the second water pipe. Since the second water pipe is arranged along the circumference of the water tank, the air around the water tank can be purified; the dust-containing air on the top of the water tank is sucked into the wide-mouth air inlet frame through the fan, and then sprayed out through the second air duct and the air nozzle. Since the air nozzle is arranged at the lower side of the spray head, the dust-containing air blown out by the air nozzle can be purified by spraying water mist through the spray head. The dust particles in the air become heavier and fall after meeting water, thereby purifying the air, and the water mist sprayed from the spray head can be blown farther through the air nozzle, and the purification range is larger and wider; by setting up the fan, the fan draws the dust-containing air on the top of the water tank to the bottom of the spray head for purification, and there is no need to spray the water mist high up. By utilizing the fluidity of the air, when the air around the wide-mouth air inlet frame is drawn away, the surrounding air will flow to the surrounding of the wide-mouth air inlet frame, thereby purifying the air around the water tank. This arrangement greatly increases the purification area of ​​the air purification device.

[0008] A further solution is that the radial width of the wide-mouth air inlet frame along the first air duct is greater than the radial width of the first air duct, the air inlet end face of the wide-mouth air inlet frame faces away from the water tank, and the air inlet end face of the wide-mouth air inlet frame is inclined.

[0009] It can be seen that the air inlet end face of the wide-mouth air inlet frame located on the top of the water tank is away from the water tank, so that the wide-mouth air inlet frame can extract dust-containing air in a larger range on the top of the water tank. The wide-mouth air inlet frame is tilted to facilitate the wide-mouth air inlet frame to face the wind, which is beneficial to the fan to exhaust air, and the tilted setting of the wide-mouth air inlet frame reduces the overall height of the device, which is beneficial to the movement of the device.

[0010] A further solution is that the angle between the air inlet end surface of the air inlet wide-mouth frame and the horizontal plane is 60 degrees.

[0011] A further solution is that an isolation net is arranged between the air inlet end surface of the wide-mouth air inlet frame and the first air duct, the isolation net is arranged inside the wide-mouth air inlet frame, and the isolation net is covered with through holes.

[0012] It can be seen that the isolation net is used to filter large pieces of garbage floating in the air to avoid blockage of the fan and the first air duct.

[0013] A further solution is that the spray head and the air nozzle are arranged in a one-to-one correspondence along the vertical direction and in a collinear manner.

[0014] It can be seen that a spray head and an air nozzle are arranged in a corresponding collinear manner in the vertical direction, so that one spray water purifies the dust-containing air blown out of one air nozzle, and the dust-containing air blown out of the air nozzle is purified more concentratedly.

[0015] A further solution is that the second water pipe and the second air duct are connected via a plurality of first connecting rods, and the first connecting rods extend in a vertical direction.

[0016] It can be seen that the first connecting rod connects and fixes the second water pipe and the second air duct, while ensuring that the second air duct is located at the lower side of the second water pipe.

[0017] A further solution is that a second connecting rod is connected between every two oppositely arranged first connecting rods, the second connecting rods extend in a horizontal direction, the second connecting rods are installed on the top surface of the water tank, and a plurality of second connecting rods are arranged in parallel.

[0018] It can be seen that the second connecting rod connects the water pipe and the air duct on the water tank to each other, and the air duct and the water pipe are arranged on the water tank.

[0019] A further solution is that a plurality of spray heads are arranged at equal distances along the axial direction of the second water pipe, and a plurality of air nozzles are arranged at equal distances along the axial direction of the second air pipe.

[0020] It can be seen that the evenly distributed spray heads make the water mist spray more evenly, and the air purification everywhere is even and thorough.

[0021] A further solution is that a water inlet is provided at the top of the water tank, and a water outlet is provided at the bottom of the water tank.

[0022] It can be seen that the setting of the water inlet and outlet on the water tank meets the needs of water storage and drainage in the water tank.

[0023] A further solution is that the air purification device includes a carrier body, and a water tank, a spray assembly and a dust collection assembly are arranged on the carrier body.

[0024] It can be seen that the carrier body enables the purification device to be movable, thereby further expanding the purification range of the air purification device. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention is further described below in conjunction with the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0029] The air purification device for construction of the present invention is applied to air purification at construction sites. The dust-containing air around the water tank is blown out below the spray head through the dust suction component through the wide-mouth air inlet frame and the fan. The dust particles in the air become heavier and fall down after meeting water, thereby purifying the air. After the air around the air purifier is extracted by using the wide-mouth air inlet frame, the surrounding air will flow to the surrounding of the wide-mouth air inlet frame, thereby purifying the air around the water tank. This arrangement greatly increases the purification area of ​​the air purification device.

[0030] See also Figure 1 and Figure 2 The air purification device for construction includes a carrier body 1, a water tank 2, a spray assembly 3 and a dust collection assembly 4. The spray assembly 3 and the dust collection assembly 4 are arranged on the top of the water tank 2. The water tank 2 is arranged on the carrier body 1. The carrier body 1 realizes the mobility of the air purification device, which greatly expands the scope and convenience of air purification. As another embodiment, the air purification device can be fixed, that is, the air purification device does not include a movable carrier body, and the water tank is placed in a fixed position where pollution occurs more seriously to purify the air around the fixed position.

[0031] In this embodiment, the water tank 2 is in a rectangular shape, a water inlet is provided at the top of the water tank 2 , and a water outlet is provided at the bottom of the water tank 2 to meet the needs of water storage and drainage of the water tank 2 .

[0032] The spray assembly 3 includes a water pump 31, two first water pipes 32 and a second water pipe 5. The water pump 31 and the second water pipe 5 are respectively arranged on the top of the water tank 2. The water pump 31 is respectively connected to the second water pipe 5 and the water tank 2 through the first water pipe 32. One of the first water pipes 32 is connected to the water pump 31 and then extends into the bottom of the water tank 2. In this embodiment, the second water pipe 5 is arranged horizontally, and the second water pipe 5 is arranged around the circumference of the water tank 2. The second water pipe 5 is divided into three sections, namely the first section 51, the second section 52 and the third section 53. The three sections of the second water pipe 5 correspond to the three sides of the water tank 2 respectively. The first section 51 and the third section 53 are parallel in the horizontal direction. The second section 52 is located between the first section 51 and the third section 53. The second section 52 is located at the tail of the carrier body 1. Another first water pipe 32 is connected to the second section 52 of the second water pipe 5.

[0033] A plurality of spray heads 54 are disposed at one end of the second water pipe 5 away from the water tank 2. In this embodiment, the plurality of spray heads 54 are arranged equidistantly along the axial direction of the second water pipe 5.

[0034] The dust collecting assembly 4 includes an air inlet wide-mouth frame 6, a fan 41, two first air ducts 42 and a second air duct 7, and the dust collecting assembly 4 is located at the top of the water tank 2. The fan 41 is connected to the air inlet wide-mouth frame 6 and the second air duct 7 through the first air duct 42, respectively, and the second air duct 7 is arranged around the circumference of the water tank 2. In this embodiment, the second air duct 7 is divided into three sections, namely, a first section 71, a second section 72 and a third section, wherein the first section 51 of the second water pipe 5 is parallel to the first section 71 of the second air duct 7, the second section 52 of the second water pipe 5 is parallel to the second section 72 of the second air duct 7, and the third section 53 of the second water pipe 5 is parallel to the third section of the second air duct 7.

[0035] A plurality of air nozzles 73 are provided at one end of the second air duct 7 away from the water tank 2. Figure 3 , the second air duct 7 is located at the lower side of the second water pipe 5, the spray head 54 is arranged toward the wind nozzle 73 or installed horizontally, and the wind nozzle 73 can be arranged toward the spray head 54 or installed horizontally. In this embodiment, a plurality of wind nozzles 73 are arranged equidistantly along the axial direction of the second water pipe 5, and the spray head 54 and the wind nozzle 73 are installed horizontally, and the spray head 54 and the wind nozzle 73 are arranged in a one-to-one correspondence in the vertical direction. A spray head 54 and a wind nozzle 73 are arranged in a corresponding collinear manner in the vertical direction, so that one spray water purifies the dusty air blown out of one wind nozzle, and the dusty air blown out of the wind nozzle is purified more concentratedly. As another embodiment, in the vertical direction, a wind nozzle can be located between two adjacent spray heads 54, and the two spray heads 54 purify the dusty air blown out of one wind nozzle, and the purification degree is more thorough.

[0036] In this embodiment, the width of the wide-mouth air inlet frame 6 along the radial direction of the first air duct 42 is greater than the radial width of the first air duct, the air inlet end face of the wide-mouth air inlet frame 6 faces away from the water tank 2, and the air inlet end face of the wide-mouth air inlet frame 6 is tilted. The angle between the air inlet end face of the wide-mouth air inlet frame 6 and the horizontal plane is 60 degrees. The air inlet end face of the wide-mouth air inlet frame 6 located at the top of the water tank 2 faces away from the water tank 2, so that the wide-mouth air inlet frame 6 extracts dusty air in a larger range of the top of the water tank 2. The wide-mouth air inlet frame 6 is tilted, which is convenient for the wide-mouth air inlet frame 6 to face the wind, which is beneficial for the fan 41 to extract air, and the tilted setting of the wide-mouth air inlet frame 6 reduces the overall height of the device, which is beneficial for the movement of the device.

[0037] An isolation net 61 is provided between the air inlet end face of the air inlet wide-mouth frame 6 and the first air duct 42. The isolation net 61 is provided inside the air inlet wide-mouth frame 6 and is covered with through holes 611. The isolation net 61 is used to filter large pieces of garbage floating in the air to avoid blockage of the fan 41 and the first air duct 42.

[0038] The second water pipe 5 and the second air pipe 7 are connected by a plurality of first connecting rods 8, which extend in the vertical direction; the first connecting rods 8 connect and fix the second water pipe 5 and the second air pipe 7, and ensure that the second air pipe 7 is located at the lower side of the second water pipe 5. A second connecting rod 9 is connected between every two first connecting rods 8 which are arranged opposite to each other, and the second connecting rod 9 extends in the horizontal direction. The second connecting rod 9 is installed on the top surface of the water tank 2, and a plurality of second connecting rods 9 are arranged in parallel; the second connecting rod 9 connects the sections arranged in the water pipe and the air pipe along the circumference of the water tank 2, ensures that the water pipe and the air pipe are arranged firmly on the water tank 2, and the air pipe and the water pipe are arranged on the water tank 2 by the second connecting rod 9.

[0039] The water pump 31 pumps the water out of the water tank 2 and sprays it out from the spray head 54 through the second water pipe 5. Since the second water pipe 5 is arranged along the circumference of the water tank 2, the air around the water tank 2 can be purified; the dust-containing air at the top of the water tank 2 is sucked into the wide-mouth air inlet frame 6 through the fan 41, and then sprayed out through the second air duct 7 and the air nozzle. Since the air nozzle is arranged on the lower side of the spray head 54, the dust-containing air blown out by the air nozzle can be purified by spraying water mist through the spray head 54. The dust particles in the air become heavier and fall down after meeting water, thereby purifying the air, and the water mist sprayed from the spray head 54 can be blown farther through the air nozzle, and the purification range is larger and wider. By setting up the fan 41, the dust-containing air on the top of the water tank 2 is drawn to the bottom of the spray head 54 for purification. There is no need to spray the water mist upward. By utilizing the fluidity of the air, when the air around the wide-mouth air inlet frame 6 is drawn away, the surrounding air will flow to the surrounding of the wide-mouth air inlet frame 6, thereby purifying the air around the water tank 2. This setting method greatly increases the purification area of ​​the air purification device.

For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
