Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust prevention in building construction, and more specifically, to a dust prevention device in building construction. Background Art
[0002] In the process of construction, sand screening is an indispensable operation, but traditional sand screening equipment usually generates a lot of dust during the sand screening process. The dust will not only pollute the air at the construction site and affect the health of the construction workers, but also have adverse effects on the surrounding environment. In the prior art, although some sand screening equipment on the market has reduced dust by adding sealing structures and filtering devices, the effect is often unsatisfactory and cannot completely solve the dust problem. Especially in large-scale construction sites, the dust problem is particularly serious, which not only affects the working environment, but also may cause troubles to the lives of surrounding residents. In addition, traditional sand screening equipment also has many deficiencies in design and manufacturing, and it is difficult to meet the requirements of modern construction for environmental protection and high efficiency;
[0003] Due to design defects, traditional sand screening equipment often has dust overflow problems during use. Specifically, when these devices are screening sand, the connection between the screen and the seal is not tight enough, which makes it easy for dust to escape from the gap. In addition, during the operation of the equipment, vibration and mechanical movement will also make the dust more easily spread, making it difficult to achieve effective dust prevention. These defects not only reduce the working efficiency of the sand screening equipment, but also increase the maintenance cost and difficulty of use of the equipment. More importantly, the existence of dust problems seriously affects the health of construction workers. Long-term exposure to dust environments can easily cause respiratory diseases and other health problems. In addition, dust also causes serious wear on the equipment, shortening the service life of the equipment and increasing the cost of replacement and maintenance. When traditional equipment handles fluids containing solid particles or mixed fluids, it is prone to scaling and wear problems, further reducing the operating efficiency of the equipment.

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Refer to the instruction manual Figure 1-7 , a construction dust prevention device according to an embodiment of the utility model comprises a conical positioning socket 1, a semicircular positioning seat 3 is fixedly installed on the top of the conical positioning socket 1, a positioning frame plate 8 is installed on the top of the semicircular positioning seat 3, the number of the conical positioning socket 1 and the positioning frame plate 8 is set to be consistent, the surface of the positioning frame plate 8 is through-shaped and has a plurality of fan-shaped notches, fan-shaped inlet and outlet blades 10 are installed at the fan-shaped notches on the surface of the positioning frame plate 8, a spring hinge 9 is installed on the top of the fan-shaped inlet and outlet blades 10, the fan-shaped inlet and outlet blades 10 are hinged at the fan-shaped notches on the surface of the positioning frame plate 8 through the spring hinge 9, and a dust-proof screen 7 for screening sand is installed at the bottom of the positioning frame plate 8; an elastic connecting portion 11 is installed between the fan-shaped inlet and outlet blades 10 and the positioning frame plate 8, wherein the elastic connecting portion 11 is used to pull the fan-shaped inlet and outlet blades 10 to move. The discharge blades 10 are kept balanced so that the positioning frame plate 8 and the fan-shaped inlet and outlet blades 10 are kept in the same plane. In actual use, the sand is poured on the surface of the positioning frame plate 8 and the fan-shaped inlet and outlet blades 10 to simulate the process of traditional sand screening. The traditional sand screening is prone to stratification and diffusion problems. In this solution, the sand is pressed on the surface of the fan-shaped inlet and outlet blades 10 by gravity, so that the fan-shaped inlet and outlet blades 10 rotate downward through the spring hinges 9, and the sand passes through the positioning frame plate 8 and enters the interior of the dustproof screen 7, thereby achieving the effect of dust reduction and sand screening. In addition, the purpose of setting the scheme in a circular shape is that since the screened sand needs to be mixed with cement of different viscosities, the conical positioning socket 1 and the positioning frame plate 8 are inserted according to the feed port of the mixer, which can also achieve dust reduction and allow the screened sand to be directly mixed;
[0026] During use, first pour the sand to be screened onto the surface of the positioning frame plate 8 and the fan-shaped inlet and outlet blades 10. Due to the effect of gravity, the sand is gradually pressed downward onto the fan-shaped inlet and outlet blades 10. At this time, the fan-shaped inlet and outlet blades 10 are pushed by gravity and rotate downward through the hinge point of the spring hinge 9. The design of the fan-shaped inlet and outlet blades 10 enables the sand to smoothly pass through the fan-shaped notch into the interior of the positioning frame plate 8 and further slide into the dust-proof screen 7. Inside the dust-proof screen 7, after the sand is screened, larger particles of sand are retained on the screen, while finer sand falls into the collection area below through the screen aperture. In this process, the diffusion of dust is effectively reduced by designing a sophisticated dust-proof structure, ensuring that the sand screening process is more environmentally friendly.
[0027] In order to adapt to different construction needs, the device is designed to be circular, which not only improves the stability of the structure, but also makes it easier to insert the conical positioning socket 1 and the positioning frame plate 8 into the feed port of the mixer. Through this design, the screened sand can be directly fed into the mixer for mixing cement of different viscosities, reducing the intermediate links and improving work efficiency. In addition, the elastic connecting portion 11 in the device can maintain balance when pulling the fan-shaped inlet and outlet blades 10, so that the positioning frame plate 8 and the fan-shaped inlet and outlet blades 10 always remain on the same plane, thereby ensuring the stability and continuity of the sand screening process. Through this design, the stratification and dust diffusion problems that are prone to occur in the traditional sand screening process have been effectively solved. In general, the device of the utility model not only improves the sand screening efficiency, but also greatly improves the air quality at the construction site, providing a more environmentally friendly and efficient solution.
[0028] The outer track contour shapes of the conical positioning socket 1 and the positioning frame plate 8 include circle and square. Because traditional sand screening structures are square, in order to adapt to different usage environments, different shapes can be used for actual use. The style shown in the drawings in the specification is circular.
[0029] Among them, the top of the conical positioning socket 1 is provided with an annular prefabricated groove 2 for support, the semicircular positioning seat 3 is fixedly installed on the top of the inner wall of the conical positioning socket 1, the top of the semicircular positioning seat 3 is clamped with a double U-shaped folding ring 5, the double U-shaped folding ring 5 is installed at the bottom of the positioning frame plate 8, and the two ends of the double U-shaped folding ring 5 are respectively installed with an extension part 1 4 and an extension part 2 6, the number of each group of extension parts 1 4 is set to two, the number of each group of extension parts 2 6 is set to two, and the top and bottom of the extension part 1 4 and the extension part 2 6 are covered with rubber anti-slip rings 16. A semicircular guide cover 12 for guiding the sand body to move toward the position of the fan-shaped inlet and outlet blades 10 is installed on the top of the positioning frame plate 8 by bolts. The outer trajectory contour shape of the semicircular guide cover 12 is consistent with the conical positioning socket 1. A transverse semicircular clamping ring 13 is fixedly installed on the outer periphery of the positioning frame plate 8. A hollow support ring 14 is fixedly installed on the top and bottom of the extension part 2 6 and the extension part 1 4. Annular positioning parts 15 are fixedly installed on both sides of the hollow support ring 14. The annular positioning part 15 is clamped in the inner cavity of the transverse semicircular clamping ring 13.
[0030] Among them, an annular seal 17 and an annular seal 2 18 for anti-buffering are installed in the middle of each group of extension parts 1 4 and each group of extension parts 2 6. The annular seal 17 and the annular seal 2 18 connect the two sections of extension parts 1 4 or extension parts 2 6. The annular seal 17 and the annular seal 2 18 are supported by rubber. The outer wall edge of the annular seal 2 18 is fixedly installed with an anti-collision extension ring 19. Figure 7 As shown, the annular seal 17 and the annular seal 2 18 and the rubber structure in the middle allow each group of extension parts 1 4 and each group of extension parts 2 6 to form a structure that can shake, so that an anti-buffering effect can be formed. In actual use, the double U-shaped folding ring 5 can allow the extension parts 1 4 and the extension parts 2 6 to form a folded shape. At the same time, according to the installation size, the conical positioning socket 1 is inserted into the conical positioning socket 1, so that the conical conical positioning socket 1 is deformed, thereby clamping the extension part 1 4 to achieve a fixing effect.
[0031] Working principle: The construction dust prevention device of the utility model realizes efficient dust prevention and sand screening effects. Specifically, the device includes multiple key components, among which the conical positioning socket 1 serves as the basic structure for supporting and fixing the entire device, and a semicircular positioning seat 3 is installed on the top. The top of the semicircular positioning seat 3 is connected to the positioning frame plate 8, and the number of the conical positioning socket 1 and the positioning frame plate 8 is consistent, ensuring the stability of the structure; in actual use, the sand is poured on the surface of the positioning frame plate 8, and the sand is allowed to enter the dust-proof screen 7 through the fan-shaped inlet and outlet blades 10 for screening by gravity. The fan-shaped inlet and outlet blades 10 are hinged to the surface of the positioning frame plate 8 by spring hinges 9, so that they can rotate flexibly, so that the sand can smoothly pass through the screen dust-proof screen 7. This process not only simulates the traditional sand screening method, but also effectively reduces the diffusion of dust. In order to further reduce dust, the utility model is provided with an elastic connection part 11 to ensure the balance between the fan-shaped inlet and outlet blades 10 and the positioning frame plate 8, so that the sand screening process is smoother;
[0032] In order to improve the dustproof effect, the device also adopts an annular seal 17 and an annular seal 2 18, which can effectively prevent dust from escaping from the device. In addition, rubber anti-slip rings 16 are installed on the bottom and sides of the device. These rings can increase the stability of the device during use, absorb part of the vibration, and reduce equipment wear. The design of the anti-collision extension ring 19 also further protects the device from damage due to impact during operation.
[0033] Compared with traditional sand screening equipment, the utility model has significant advantages. When traditional equipment processes fluids containing solid particles or mixed fluids, scaling and wear problems are prone to occur. However, the utility model greatly reduces the occurrence of these problems through optimized design and the use of wear-resistant materials. The annular seal and anti-slip ring in the device ensure the sealing and anti-slip performance, and improve the reliability and durability of the device in use.
[0034] The device of the utility model also has a wide range of application potentials. It is not only suitable for the sand screening process in construction, but also can be used in mining, metallurgy, chemical industry and other fields. By improving the material and structure of the dust-proof screen 7, it can adapt to the screening and dust-proof requirements of different materials. In addition, by adjusting the size and shape of the device, it can adapt to different use environments and improve the versatility and practicality of the equipment. For example, in mining, the device can effectively screen ore while reducing dust pollution; in the metallurgical industry, the device can screen metal particles and improve production efficiency;
[0035] In general, the utility model solves the dust problem existing in traditional sand screening equipment through innovative structural design and function optimization, significantly improves the sand screening efficiency and dust prevention effect, and ensures the sealing and stability of the device during use by adopting components such as annular seals and rubber anti-slip rings, reduces maintenance costs, and extends the service life of the equipment. The versatility and wide applicability of the device enable it to play an important role in different fields and scenarios. Compared with the existing technology, the utility model has significant advantages in dust prevention effect, sand screening efficiency, equipment reliability and service life, and has good application prospects and market value.
