Description

Technical Field

[0001] The utility model relates to the field of concrete processing and mixing equipment, in particular to a dust reduction device for commercial concrete crushed powder. Background Art

[0002] The commercial concrete crushing powder dust reduction device is mainly designed to reduce dust pollution during the mixing process of commercial concrete. It can effectively collect and filter out dust particles in the air, reduce the emission concentration of dust, and thus protect the environment and human health.

[0003] Traditional commercial concrete crushed powder dust reduction devices mostly use wet dust collectors. In order to improve the dust removal effect of the wet dust collector and avoid dead corners, the dust collector is generally rotated. In order to ensure that the dust collector can rotate, additional power parts are required, which may increase the complexity of the equipment and the difficulty of maintenance. Any failure of the electric parts may cause the entire mixing device to shut down, and the maintenance time and cost will increase accordingly. In addition, adding additional power parts means more capital investment, including purchase cost, installation cost and commissioning cost, which may increase the economic burden of the enterprise. Therefore, when designing the commercial concrete crushed powder dust reduction device, it can be rotated without affecting the rotation of the wet dust collector. It only needs to use the basic power source of the commercial concrete crushed powder mixing equipment to reduce maintenance costs and purchase costs, and improve overall practicality. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a commercial concrete crushed material dust reduction device to solve the technical problems of high maintenance cost and purchase cost of traditional commercial concrete crushed material dust reduction devices.

[0006] An installation pipeline is provided inside the installation rod, a liquid pipeline is provided inside the installation pipeline, a spray plate is provided at the bottom of the installation rod, and a plurality of spray ports are provided at the outer side of the bottom of the spray plate.

[0007] By adopting the above technical solution, since a motor is arranged on one side of the top of the base, and a first rotating rod is arranged at the output end of the motor, the motor can effectively drive the first rotating rod to rotate.

[0008] Furthermore, a second rotating rod is arranged at the bottom axis of the spray plate, and a stirring blade is arranged at the bottom of the second rotating rod.

[0009] By adopting the above technical solution, since the second rotating rod is arranged at the bottom axis of the spray plate, the second rotating rod can be effectively driven to rotate after the spray plate rotates.

[0010] Furthermore, the number of stirring blades is four, and the four stirring blades are equidistantly arranged in a circular array.

[0011] By adopting the above technical solution, the four stirring blades can ensure that the crushed powder is subjected to the same stirring force in all directions, thereby achieving a more uniform stirring effect, which helps to improve the quality and consistency of concrete.

[0012] Furthermore, a first gear is disposed on the outer surface of the first rotating rod, and a mixing drum is disposed on one side of the motor.

[0013] By adopting the above technical solution, since the first gear is disposed on the outer surface of the first rotating rod, the first gear can be driven to rotate after the first rotating rod rotates.

[0014] Furthermore, a second gear is disposed on the outer surface of the mixing drum, and the first gear is meshed with the second gear.

[0015] By adopting the above technical solution, since the outer surface of the mixing drum is provided with a second gear, the mixing drum can be driven by the second gear.

[0017] By adopting the above technical solution, the extension rod can be limited by the mounting frame.

[0018] Furthermore, a plurality of the spray ports are provided, and the plurality of the spray ports are arranged equidistantly in a linear array.

[0019] By adopting the above technical solution, a wider mixing area can be covered through multiple spray ports, ensuring that the dust generated during the mixing process is moistened and settled in a timely and effective manner. This design can greatly reduce the diffusion of dust during mixing, thereby improving the working environment and reducing health hazards to operators.

[0020] Furthermore, a mixing drum is connected to the top of the base via a rotating seat, and the mixing drum is arranged in a barrel-shaped structure.

[0021] By adopting the above technical solution, since the top of the base is connected to the mixing drum via the rotating seat, the mixing drum itself can be ensured to rotate via the rotating seat.

[0022] Furthermore, the base, the mounting frame and the fixing column are made of aluminum alloy, and the mixing drum is made of stainless steel.

[0023] By adopting the above technical solution, aluminum alloy is a lightweight metal with lower density and lighter weight than traditional steel materials.

[0024] Furthermore, the motor is electrically connected to an external controller.

[0025] By adopting the above technical solution, the motor can be accurately controlled by an external controller, including starting, stopping, speed adjustment, etc.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] 1. The utility model sets a transmission mechanism. When the motor drives the first rotating rod to rotate, it drives the extension rod to rotate, and then the extension rod drives the first sprocket to rotate. Then the first sprocket can effectively drive the second sprocket to rotate. At this time, the second sprocket can effectively drive the installation rod to rotate. During the rotation of the installation rod, the spray plate will be driven to rotate. Then, when the external liquid pump is started, the spray port can be driven to spray water. Through the above-mentioned setting, there is no need to configure electric parts for the spray plate separately, thereby simplifying the power wiring and equipment configuration, reducing the installation and maintenance costs. By using a common power source, the operation of the spray plate will not increase additional energy consumption, which is helpful to achieve the goal of energy saving and environmental protection. In addition, during the rotation of the spray plate, the dust generated during the stirring process can be effectively suppressed, the working environment can be improved, and the health hazards of dust to operators can be reduced.

[0028] 2. The utility model sets a first gear, a second gear and a second rotating rod. In the first rotating rod, after the motor is started, the first rotating rod will first drive the first gear to rotate, and the first gear can drive the second gear to rotate, and then the second gear will drive the mixing drum to rotate, so as to better mix the concrete. After the spray plate rotates, it can drive the second rotating rod to rotate, and then the second rotating rod can drive the stirring blade to stir. Through the above-mentioned arrangement, only one motor can be used to effectively drive the mixing drum, stirring blade and spray plate to rotate, thereby improving the overall practicality.

[0038] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A second rotating rod 10 is provided at the bottom axis of the spray plate 904, and a stirring blade 11 is provided at the bottom of the second rotating rod 10. Therefore, after the spray plate 904 rotates, the second rotating rod 10 can be effectively driven to rotate, and the stirring blade 11 can effectively drive the commercial concrete crushed powder to be stirred.

[0039] Embodiment 2:

[0040] See also Figure 1 , Figure 2 , Figure 3 There are four stirring blades 11, which are arranged equidistantly in a circular array. The four stirring blades 11 can ensure that the crushed powder is subjected to the same stirring force in all directions, thereby achieving a more uniform stirring effect, which helps to improve the quality and consistency of concrete. Moreover, the stirring blades 11 arranged in a circular array can cover the entire cross-section of the mixing drum, reducing or eliminating dead corners in stirring.

[0041] See also Figure 1 , Figure 2 , Figure 3 A first gear 6 is disposed on the outer surface of the first rotating rod 4, and a mixing drum 7 is disposed on one side of the motor 3. Therefore, after the first rotating rod 4 rotates, the first gear 6 can be driven to rotate, and the mixing drum 7 can effectively process commercial concrete.

[0042] See also Figure 1 , Figure 2 , Figure 3 A second gear 8 is provided on the outer surface of the mixing drum 7, and the first gear 6 and the second gear 8 are meshed with each other, so the mixing drum 7 can be driven by the second gear 8, and the first gear 6 can effectively drive the second gear 8 to rotate after rotating.

[0043] See also Figure 1 , Figure 2 , Figure 3 The top of the mounting frame 2 is rotatably connected to the top of the extension rod 5 through an extension bracket. The extension rod 5 can be limited by the mounting frame 2 and can ensure that the extension rod 5 can rotate normally.

[0044] See also Figure 1 , Figure 2 , Figure 3 , Figure 4There are multiple spray ports 906, which are equidistantly arranged in a linear array. A wider mixing area can be covered by multiple spray ports 906, ensuring that the dust generated during the mixing process is moistened and settled in a timely and effective manner. This design can greatly reduce the diffusion of dust during mixing, thereby improving the working environment and reducing health hazards to operators. Moreover, the spray ports 906 are equidistantly arranged in a linear array, ensuring uniform spraying of water mist or liquid, which can not only improve the dust reduction effect, but also avoid quality problems of materials due to local over-wetting or over-drying.

Therefore, the rotating seat can ensure that the mixing drum 7 itself can rotate, and the barrel-shaped structure can maximize the use of space and provide a larger effective volume, so as to accommodate more crushed powder for mixing, which helps to improve the mixing efficiency and reduce the mixing time.

[0046] See also Figure 1 , Figure 2 , Figure 3 The base 1, the mounting frame 2, and the fixing column 12 are made of aluminum alloy, and stainless steel is an alloy steel containing chromium, which can form a dense oxide film on its surface, effectively resisting corrosion from the atmosphere, water, and various chemical substances. During the mixing process of commercial concrete, the mixing drum is often in contact with water, cement, aggregates, and other additives. The stainless steel material can ensure that it is not easily damaged during long-term use. Aluminum alloy is a lightweight metal with a lower density and lighter weight than traditional steel materials. Therefore, the base 1, the mounting frame 2, and the fixing column 12 are easy to install.

[0047] See also Figure 1 , Figure 2 , Figure 3 The motor 3 is electrically connected to the external controller, and the motor 3 can be precisely controlled by the external controller, including starting, stopping, speed adjustment, etc., and the external controller usually has functions such as overload protection and short circuit protection. When a fault occurs in the motor 3 or the equipment, the power supply can be cut off in time to avoid the expansion of the fault, thereby protecting the safety of the motor and the equipment.

[0048] The implementation principle of the utility model is as follows: first, the mixing equipment of commercial concrete crushed powder needs to be installed on the bottom surface through the base 1, and it is ensured that the motor 3 can be connected to the power supply, and then the motor 3 can be started, and then the first rotating rod 4 of the motor 3 will drive the first gear 6 to rotate, and the first gear 6 can drive the second gear 8 to rotate, and then the second gear 8 will drive the mixing drum 7 to rotate, so as to better mix the concrete;

[0049] Afterwards, the first rotating rod 4 can effectively drive the extension rod 5 to rotate during its rotation, and then the extension rod 5 will drive the first sprocket 901 to rotate, and then the first sprocket 901 can effectively drive the second sprocket 902 to rotate, and then the second sprocket 902 can effectively drive the installation rod 903 to rotate, and the installation rod 903 will drive the spray plate 904 to rotate during its rotation, and then when the external liquid pump is started, the spray port 906 can spray water;

[0050] After the spray plate 904 rotates, it can drive the second rotating rod 10 to rotate, and then the second rotating rod 10 can drive the stirring blade 11 to stir. Through the above arrangement, only one motor 3 can effectively drive the stirring drum 7, the stirring blade 11 and the spray plate 904 to rotate, thereby improving the overall practicality.
