Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment support structure technology, and in particular to an intermediate support structure for a magnetic concrete and sand loading mixer. Background Technology

[0002] In wastewater treatment and related fields, magnetic coagulation and sand loading processes have been widely used due to their high treatment efficiency. With the continuous development of this process, the requirements for the performance and stability of treatment equipment are also increasing. As a crucial treatment stage, the operation of the internal mixer in the magnetic coagulation and sand loading mixing tank directly affects the overall treatment effect. Proper mixer operation ensures thorough mixing of wastewater with magnetic materials and sand powder, improving treatment efficiency, reducing pollutant emissions, and is of great significance for environmental protection and the rational utilization of water resources.

[0003] In traditional magnetic coagulation and sand loading processes, when the mixing tank is deep, the mixer spindle is typically supported by an intermediate support to ensure its stability. To address potential wear, the traditional approach is to replace the wear-resistant sleeve after the support component wears down. If the wear is severe, it may even be necessary to replace the spindle steel sleeve. These two methods are common in practice and have long been the main means of addressing the wear problem of support components in the industry.

[0004] However, existing methods for combating wear have significant shortcomings. Under the influence of magnetic materials or sand, the intermediate support wears relatively quickly. Frequent replacement of wear-resistant sleeves or spindle steel sleeves not only increases maintenance costs but also makes on-site operation extremely inconvenient, requiring a significant amount of manpower and time, thus affecting the normal operation of the equipment and production efficiency. Utility Model Content

[0005] This application provides an intermediate support structure for a magnetic concrete and sand loading mixer. By quickly adjusting the wear position of the wear-resistant sleeve, the utilization rate and life of the wear-resistant sleeve are improved, thereby ensuring a more stable support effect.

[0006] This application provides a middle support structure for a magnetic concrete and sand loading mixer, which adopts the following technical solution:

[0007] A central support structure for a magnetic concrete and sand loading mixer includes a mixer main shaft. A coaxial wear-resistant metal bushing is provided on the outer side of the mixer main shaft. Multiple wear-resistant blocks are provided on the outer side of the coaxial wear-resistant metal bushing. The wear-resistant blocks are circumferentially distributed and their positions can be adjusted radially. A fixing structure and an assembly base are respectively provided on both sides of the wear-resistant blocks. An axial adjustment structure is provided on the assembly base. The axial adjustment structure is used to adjust the wear position of the wear steel bushing. The axial adjustment structure is fixed on the central support rigid beam.

[0008] By adopting the above technical solution, the present invention designs an intermediate support structure for a magnetic concrete and sand loading mixer. In use, a coaxial wear-resistant metal bushing is set on the outside of the mixer's main shaft, and wear-resistant blocks with radially adjustable positions are distributed around its outer circumference. Fixed structures and assembly bases are respectively set on both sides of the wear-resistant blocks. An axial adjustment structure is set on the assembly base and fixed on the intermediate support rigid beam, which can achieve rapid adjustment and improve service life.

[0009] Preferably, the coaxial wear-resistant metal bushing and the mixer spindle are interference-fitted.

[0010] By adopting the above technical solution, the coaxial wear-resistant metal bushing and the mixer main shaft are interference-fitted during use, making the connection between the two tighter and more stable, and improving the overall structure.

[0011] Preferably, the fixing structure includes a wear-resistant block support provided on one side of the wear-resistant block, and the wear-resistant block support is provided with a clamping bolt, which fixes the wear-resistant block support and the wear-resistant block to each other.

[0012] By adopting the above technical solution, the wear-resistant block support and the wear-resistant block can be fixed together by tightening bolts during use, which helps to maintain the stability of the entire intermediate support structure, facilitates wear compensation and adjustment, and thus achieves rapid adjustment and improves the service life of the intermediate support structure of the mixer.

[0013] Preferably, a wear-resistant block metal pressure plate is also provided between the wear-resistant block support and the wear-resistant block.

[0014] By adopting the above technical solution, a metal pressure plate for the wear-resistant block can be set between the wear-resistant block support and the wear-resistant block during use, which can further optimize the installation and fixing structure of the wear-resistant block and improve the overall stability.

[0015] Preferably, the wear-resistant blocks are circumferentially distributed and use a four-point centering support method. The wear-resistant blocks are used at four points, allowing for radial adjustment.

[0016] By adopting the above technical solution, the four-point centering support with wear-resistant blocks distributed circumferentially and capable of radial adjustment can solve the compensation requirement for wear of the intermediate support, achieve rapid adjustment, and improve the service life of the intermediate support structure of the magnetic concrete and sand loading mixer.

[0017] Preferably, the axial adjustment structure includes multiple adjusting bolts and an axial position adjusting screw, wherein the axial position adjusting screw passes through the assembly base and is threadedly connected to the intermediate support rigid beam.

[0018] By adopting the above technical solution, the wear position of the worn steel sleeve can be precisely adjusted by using the adjusting bolts and axial position adjusting screws in the axial adjustment structure during use, thereby achieving rapid adjustment and improving the maintainability of the equipment.

[0019] In summary, this application has the following beneficial effects:

[0020] 1. The present invention relates to a magnetic concrete and sand loading mixer intermediate support structure, wherein the wear-resistant blocks are circumferentially distributed and their positions can be adjusted radially to meet wear compensation requirements and achieve rapid adjustment;

[0021] 2.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0026] This utility model discloses an intermediate support structure for a magnetic concrete and sand loading mixer, such as... Figure 1 and Figure 2 As shown, the assembly includes a mixer main shaft 1, a coaxial wear-resistant metal bushing 2, multiple wear-resistant blocks 3, a fixing structure 4, an assembly base 5, an axial adjustment structure 6, and an intermediate support rigid beam 7. The coaxial wear-resistant metal bushing 2 is installed on the outer side of the mixer main shaft 1, and multiple wear-resistant blocks 3 are installed on the outer side of the coaxial wear-resistant metal bushing 2. The fixing structure 4 and the assembly base 5 are respectively installed on both sides of the wear-resistant blocks 3. The axial adjustment structure 6 is installed on the assembly base 5 and fixed to the intermediate support rigid beam 7. This structure solves the problem of rapid wear and inconvenient replacement of existing intermediate supports. The wear position of the wear-resistant steel bushing is adjusted by the axial adjustment structure 6, and the setting and adjustability of the wear-resistant blocks 3 allow for rapid adjustment during wear, greatly improving service life.

[0027] Specifically, the mixer spindle 1 is the core rotating component of the entire structure. It is usually made of high-strength alloy steel, which has good strength and toughness to withstand the torque and impact force during the mixing process.

[0028] A coaxial wear-resistant metal bushing 2 is installed on the outside of the mixer main shaft 1, and is interference-fitted with the mixer main shaft 1. This interference fit ensures that the bushing fits tightly against the main shaft, preventing relative sliding between the two and ensuring transmission stability. This bushing is generally made of bronze, a material with good wear resistance. Bronze has excellent self-lubricating properties and wear resistance, effectively reducing wear on the main shaft.

[0029] Multiple wear-resistant blocks 3 are arranged circumferentially on the outer side of the coaxial wear-resistant metal bushing 2, using a four-point centering support method. The wear-resistant blocks 3 are used at all four points, allowing for radial adjustment. The wear-resistant blocks 3 provide support and reduce wear. The fixing structure 4 includes a wear-resistant block 3 support on one side of each wear-resistant block 3, with clamping bolts 42 securing the support and the wear-resistant blocks 3 together. The wear-resistant block 3 support is generally made of cast iron, providing sufficient strength to secure the wear-resistant blocks 3. The clamping bolts 42 are high-strength carbon steel bolts to ensure a firm connection. A wear-resistant block 3 metal pressure plate, typically made of stainless steel, is also provided between the support and the wear-resistant blocks 3, further increasing the contact area between the wear-resistant blocks 3 and the support, thus improving the stability of the fixation.

[0030] The assembly base 5 is the foundational component of the entire support structure, providing a platform for the installation and support of other components.

[0031] The axial adjustment structure 6 includes multiple adjusting bolts 61 and an axial position adjusting screw 62. The axial position adjusting screw 62 passes through the assembly base 5 and is threadedly connected to the intermediate support rigid beam 7. The adjusting bolts 61 can be used to fine-tune the position of the assembly base 5, while the axial position adjusting screw 62 enables axial movement of the assembly base 5, thereby adjusting the wear position of the wear sleeve. Both the adjusting bolts 61 and the axial position adjusting screw 62 are made of high-strength alloy steel to ensure their reliability during the adjustment process.

[0032] Working Principle: The intermediate support structure of the magnetic concrete and sand loading mixer in this embodiment adopts a four-point centering support method, using wear-resistant blocks 3 to support the main shaft. The wear-resistant blocks 3 are radially adjustable to adapt to different wear conditions. At the same time, the axial adjustment structure 6 can easily adjust the wear position of the wear-resistant steel sleeve, avoiding the trouble of frequently replacing the wear-resistant sleeve and the main shaft steel sleeve, reducing the difficulty and time of on-site operation, improving the efficiency and stability of the equipment, and extending the service life of the equipment.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
