Description

Technical Field

[0001] This application belongs to the field of sand mill technology, and particularly relates to a grader structure with adjustable blade angle for a sand mill. Background Technology

[0002] Sand mills, as important grinding equipment, are widely used in the crushing and grading of various materials. The classifying wheel, as one of the core components of a sand mill, directly affects the overall efficiency and effectiveness of the equipment. Traditional classifying wheel blades are typically made of square tubes lined with polyurethane. While this design meets basic grading requirements to some extent, it has revealed many shortcomings in practical applications.

[0003] The existing blade design of classifiers involves lining a square tube with polyurethane material and then fitting it onto the square fingers of the classifier. While this installation method is simple, the adjustment angle of the blades is very limited, typically only 90 degrees. This limitation restricts the range of adjustment for the back thrust of the classifier in actual production, making it unsuitable for complex and varied operating environments.

[0004] Therefore, it is particularly important to develop a classifier structure with adjustable blade angle to address the problems existing in the design of existing classifier blades. Utility Model Content

[0005] The purpose of this application is to provide a classifier wheel structure with adjustable blade angle for a sand mill, which can solve the above-mentioned problems.

[0006] The purpose of this application is to provide a classifier structure with adjustable blade angle for a sand mill, comprising:

[0007] Tiered roulette;

[0008] Grader blades;

[0009] Graded wheel rims;

[0010] The positioning plate is set on the grading wheel, and has a square hole inside and multiple protrusions on the outside that cooperate with the blades of the grading wheel.

[0011] The blade direction can be adjusted at multiple angles by adjusting the positioning plate.

[0012] The aforementioned adjustable-blade classifier structure for a sand mill allows for precise control of the material classification process within the mill by adjusting the blade angle. Different blade angles alter the force exerted on the material on the classifier, thus affecting the classification effect. Adjusting the blade angle according to actual needs enables precise control of material particle size, improving classification accuracy and efficiency. Each angle adjustment alters the counter-propulsion force of the classifier, and combined with different blade shapes, allows for multi-gradient adjustment of the counter-propulsion force. Furthermore, the square inner hole of the positioning plate prevents rotation, and multiple protrusions on the outer surface of the positioning plate engage with the classifier blades.

[0013] Furthermore, the design of the grading wheel structure in this application simplifies and facilitates blade replacement and adjustment. The number of protrusions can be increased as needed. Therefore, in actual operation, the blade angle can be quickly changed with simple adjustments, reducing not only operational difficulty but also maintenance costs and time. In summary, the positioning plate significantly improves the grading accuracy, efficiency, adaptability, and service life of the sand mill, while simplifying maintenance and operation.

[0014] Furthermore, the protrusion and the positioning plate are an integral structure, and the protrusion is arc-shaped and has twelve protrusions.

[0015] Because the protrusions and positioning plates are integrated into one structure, the structural strength can be improved. By setting twelve protrusions, each adjustment corresponds to a 30-degree rotation, allowing for adjustments of 0, 30, 60, and 90 degrees. Furthermore, the number of protrusions can be increased as needed, providing more adjustable angles for the grading wheel blades.

[0016] Furthermore: the grading wheel is provided with a connecting rod that connects to the grading wheel ring. The connecting rod includes a rod body and connectors at both ends of the rod body. The cross-section of the rod body is square and mates with the square holes of the positioning plate.

[0017] The connecting rod, serving as the structural link between the grading disc and the grading rim, enhances the stability and robustness of the entire grading wheel structure. The rod's cross-section is designed to be square, fitting perfectly with the inner hole of the positioning plate to prevent rotation. Furthermore, connectors at both ends of the connecting rod simplify and expedite the connection between the grading disc and the grading rim. In actual installation, simply insert the connector into the corresponding connecting hole and secure it with fasteners. This not only reduces installation difficulty but also facilitates subsequent maintenance and replacement.

[0018] Furthermore, the grading wheel blades include:

[0019] The blade itself;

[0020] The connecting parts are located at both ends of the blade body;

[0021] The connecting part is provided with an inwardly recessed groove that matches the protrusion.

[0022] The inwardly recessed groove on the connecting part fits tightly with the protrusion on the positioning plate of the grading wheel, enhancing the stability of the grading wheel blades after mating. This prevents the grading wheel blades from rotating and allows for multi-angle adjustments based on the fit between the protrusion and the groove. Simultaneously, the fit between the groove and the protrusion simplifies and speeds up the installation and adjustment of the grading wheel blades. In practice, simply aligning the connecting part of the blade with the protrusion on the positioning plate secures the blade, reducing installation difficulty and facilitating subsequent blade angle adjustments and maintenance.

[0023] Furthermore, the blade body has a convex octagonal cross-section, and a positioning groove for installing the connecting part is provided on the blade body.

[0024] The convex octagonal cross-sectional shape allows the blade body to better resist centrifugal force during rotation, reducing vibration and deformation, thereby improving the overall stability of the grading wheel and providing better structural strength. The positioning groove allows for more accurate installation of the connecting part onto the blade body, reducing installation difficulty and errors. Simultaneously, the tight fit between the positioning groove and the connecting part increases the connection strength between the blade body and the connecting part, ensuring that the blade will not detach or loosen during rotation.

[0025] The beneficial effects of this application are:

[0026] 1. In this application, the classification process of materials in a sand mill can be precisely controlled by adjusting the angle of the classifying wheel blades. Different blade angles will cause changes in the force on the material on the classifying wheel, thus affecting the classification effect. Therefore, adjusting the blade angle according to actual needs can achieve precise control of material particle size and improve classification accuracy and efficiency.

[0027] 2. Each time the angle is adjusted, the reverse thrust of the classifier wheel will change to a certain extent. With different blade shapes, the reverse thrust of the classifier wheel can be adjusted in multiple gradients. The design of the classifier wheel structure in this application makes the replacement and adjustment of the blades simpler and more convenient. The number of protrusions can be increased according to the needs. The blade angle can be quickly changed with simple adjustments, which not only reduces the difficulty of operation, but also reduces maintenance costs and time.

[0028] 3. The inwardly recessed groove on the connecting part fits tightly with the protrusion on the positioning plate of the grading wheel, which enhances the stability of the grading wheel blades after fitting. This not only prevents the grading wheel blades from rotating, but also allows for multi-angle adjustment based on the fit between the protrusion and the groove. Attached Figure Description

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0036] The adjustable blade angle classifier structure for mills provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0037] Example 1:

[0038] like Figures 1 to 4 As shown in the figure, this application provides a classifier wheel structure with adjustable blade angle for a sand mill, comprising:

[0039] 100 tiered roulette wheels;

[0040] Grader blades 200;

[0041] Graded wheel rim 300;

[0042] The positioning plate 400 is set on the grading wheel 100. It has a square hole 410 inside and multiple protrusions 420 that cooperate with the grading wheel blades 200 on the outside.

[0043] The blade direction can be adjusted at multiple angles by adjusting the positioning plate 400.

[0044] In some embodiments of this application, such as Figure 1 As shown, the above-mentioned adjustable blade angle classifying wheel structure for a sand mill allows for precise control of the material classification process within the sand mill by adjusting the angle of the classifying wheel blades 200. Different blade angles cause changes in the force exerted on the material on the classifying wheel, thus affecting the classification effect. Adjusting the blade angle according to actual needs enables precise control of material particle size, improving classification accuracy and efficiency. Each angle adjustment alters the counter-propulsion force of the classifying wheel, and combined with different blade shapes, allows for multi-gradient adjustment of the counter-propulsion force. Simultaneously, the square inner hole of the positioning plate 400 prevents rotation, and multiple protrusions 420 on the exterior of the positioning plate 400 engage with the classifying wheel blades 200.

[0045] Furthermore, the design of the grading wheel structure in this application simplifies and facilitates blade replacement and adjustment. The number of protrusions 420 can be increased as needed. Therefore, in actual operation, the blade angle can be quickly changed with simple adjustments, reducing not only operational difficulty but also maintenance costs and time. In summary, the positioning plate 400 significantly improves the grading accuracy, efficiency, adaptability, and service life of the sand mill, while simplifying maintenance and operation.

[0046] In addition, the protrusion 420 and the positioning plate are integrated into one structure. The protrusion 420 is arc-shaped and has twelve protrusions.

[0047] Since the protrusion 420 and the positioning plate 400 are integrated, the structural strength can be improved. By setting twelve protrusions 420, each adjustment is a 30-degree rotation, which can achieve angle adjustments of 0 degrees, 30 degrees, 60 degrees, and 90 degrees. At the same time, the number of protrusions 420 can be increased as needed, so that the grader blade 200 has more adjustable angles.

[0048] Example 2:

[0049] This application provides a classifier wheel structure with adjustable blade angle for mills. In addition to the above-mentioned technical features, the classifier wheel structure with adjustable blade angle for mills in this application also includes the following technical features.

[0050] like Figure 1 As shown, the grading wheel 100 is provided with a connecting rod 110 that is connected to the grading wheel rim 300. The connecting rod 110 includes a rod body 111 and connectors 112 provided at both ends of the rod body 111. The cross-section of the rod body 111 is square and it mates with the square hole 410 of the positioning plate 400.

[0051] In this embodiment, the connecting rod 110 serves as the structure between the grading disc 100 and the grading rim 300, enhancing the stability and robustness of the entire grading wheel structure. The rod body 111 has a square cross-section, which mates with the inner hole of the positioning plate 400, preventing the positioning plate 400 from rotating. Simultaneously, connectors 112 are provided at both ends of the connecting rod 110, making the connection between the grading disc 100 and the grading rim 300 simpler and faster. In actual installation, simply insert the connector 112 into the corresponding connecting hole and secure it with fasteners, reducing installation difficulty and facilitating subsequent maintenance and replacement.

[0052] Example 3:

[0053] This application provides a classifier wheel structure with adjustable blade angle for mills. In addition to the above-mentioned technical features, the classifier wheel structure with adjustable blade angle for mills in this application also includes the following technical features.

[0054] like Figures 1 to 4 As shown, the stager blade 200 includes:

[0055] Blade body 210;

[0056] Connecting parts 220 are provided at both ends of the blade body 210;

[0057] The connecting part 220 is provided with an inwardly recessed groove 230 that engages with the protrusion 420.

[0058] In this embodiment, the inwardly recessed groove 230 on the connecting portion 220 closely engages with the protrusion 420 on the positioning plate 400 of the grading wheel 100, enhancing the stability of the grading wheel blades 200 after engagement. This prevents the grading wheel blades 200 from rotating and allows for multi-angle adjustments based on the engagement of the protrusion 420 and the groove 230. Simultaneously, the engagement of the groove 230 and the protrusion 420 simplifies and speeds up the installation and adjustment of the grading wheel blades 200. In practice, simply aligning the connecting portion 220 of the blade with the protrusion 420 on the positioning plate 400 is sufficient to fix the blade, reducing installation difficulty and facilitating subsequent blade angle adjustments and maintenance.

[0059] Furthermore, the blade body 210 has a convex octagonal cross section, and a positioning groove 211 for mounting the connecting part 220 is provided on the blade body 210.

[0060] In some embodiments of this application, the convex octagonal cross-sectional shape allows the blade body 210 to better resist centrifugal force during rotation, reducing vibration and deformation, thereby improving the overall stability of the grading wheel and providing better structural strength. The positioning groove 211 allows the connecting part 220 to be more accurately installed on the blade body 210, reducing installation difficulty and errors. Simultaneously, the tight fit between the positioning groove 211 and the connecting part 220 increases the connection strength between the blade body 210 and the connecting part 220, ensuring that the blade will not detach or loosen during rotation.
