Description

Technical Field

[0001] This application belongs to the field of grinding machine technology, and particularly relates to a mixing disc structure for a grinding machine. Background Technology

[0002] The grinding mill consists of a frame, cylinder, grinding discs, stirring shaft, and variable frequency motor. The grinding media consists of fine grinding beads, which make up approximately 70% of the grinding chamber. The grinding discs are mounted at fixed intervals on a vertical stirring shaft, which is installed inside the cylinder. The rotation of the stirring shaft and grinding discs causes the grinding beads and material to be intensely stirred and tumbled within the cylinder, increasing the contact area between them. The high-speed circling, friction, and impact of the grinding beads result in strong shearing, friction, and grinding effects on the material.

[0003] A Chinese patent with publication number CN208161727U discloses a vertical sand mill impeller, including a dispersing shaft. One end of the dispersing shaft is provided with a coupling, and a dispersing disc is sleeved on the dispersing shaft. The dispersing discs are evenly and equidistantly arranged, and circular holes are evenly arranged around the dispersing discs. The dispersing discs are also provided with a raised edge, which extends radially from the center of the dispersing disc to the edge of the dispersing disc. A balance wheel is fixed at the other end of the dispersing shaft.

[0004] Although the impeller of the aforementioned sand mill improves the mixing effect, the mixing disc will wear and break after long-term use, affecting the mixing effect. However, the mixing disc is installed in the base cylinder and is not easy to inspect. Therefore, this issue needs to be addressed. Utility Model Content

[0005] The purpose of this application is to address the aforementioned technical problems by providing a mixing disc structure for a grinding machine that can detect the wear of the mixing disc and ensure continuous mixing effect.

[0006] This application provides a mixing disc structure for a grinding mill, including:

[0007] Stirring shaft;

[0008] The mixing tray has several parts distributed on the mixing shaft;

[0009] The protruding pillars are distributed on both sides of the mixing plate and near the periphery;

[0010] The first sensor is installed in the protrusion;

[0011] The second sensor is installed on the mixing plate;

[0012] A sleeve is placed between adjacent mixing discs;

[0013] A retaining sleeve is installed at the end of the stirring shaft;

[0014] The stirring shaft and the stirring plate are connected by a key.

[0015] The mixing discs and sleeves are alternately installed on the mixing shaft. A fixing sleeve is installed at the end of the mixing shaft to fix both the mixing discs and sleeves to the mixing shaft. Different numbers of mixing discs can be set on the mixing shaft by using sleeves of different sizes, which can be used for grinding machines with different requirements. The fixing sleeve is connected to the mixing shaft by bolts and other fasteners, and the mixing shaft and the mixing discs are connected by keys to further improve the connection and tightness between the mixing discs and the mixing shaft. The protrusions are installed on the mixing discs to improve the mixing effect of the mixing discs. During the mixing process, the mixing discs will rub and collide with the grinding beads. Over time, the mixing discs will wear down. The protrusions are close to the periphery of the mixing discs and wear down faster. A first sensor is set to detect the wear of the protrusions, and a second sensor is set to detect the wear of the edge of the mixing discs. The first and second sensors are pressure sensors. When the mixing discs wear down, the first and second sensors will detect abnormal signals, ensuring the stability of the mixing disc structure of the grinding machine during use.

[0016] Furthermore, the protruding post includes:

[0017] The first mounting hole is provided with a first mounting part;

[0018] The mounting flange is placed on the protrusion and close to the opening of the first mounting hole;

[0019] The mixing plate is provided with an installation groove, which corresponds to and engages with the installation flange.

[0020] The first sensor is installed in the first mounting hole. The first sensor and the first mounting part are connected and sealed by fasteners. The mounting flange cooperates with the mounting groove. The protrusion is installed on the stirring plate by fasteners. The first mounting hole is filled with buffer solution to reduce the impact of vibration on the first sensor and improve the detection accuracy of the first sensor.

[0021] Furthermore, the stirring pan includes:

[0022] The first sealing gasket is placed between the protrusion and the mixing plate;

[0023] The second mounting hole is connected to the mounting groove, and the axis of the second mounting hole is perpendicular to the axis of the first mounting hole;

[0024] The mounting groove is provided with a second mounting part that connects to the second mounting hole.

[0025] The first sealing gasket improves the sealing between the protrusion and the stirring plate. The second sensor is installed in the second mounting hole. The second sensor and the second mounting part are connected and sealed by fasteners. The second mounting hole is filled with buffer solution to reduce the impact of vibration on the second sensor and improve the detection accuracy of the second sensor.

[0026] Furthermore, the mixing plate also includes:

[0027] The second sealing gasket is placed on the mixing plate and abuts against the corresponding sleeve and fixing sleeve.

[0028] The second sealing gasket improves the sealing between the mixing disc and the sleeve and fixed sleeve, further ensuring the connection stability between the mixing shaft, mixing disc, sleeve and fixed seat.

[0029] Furthermore, the mixing plate also includes:

[0030] First end face teeth;

[0031] The sleeve is provided with a second end face tooth corresponding to the corresponding first end face tooth, and the fixing sleeve is provided with a third end face tooth corresponding to the corresponding first end face tooth.

[0032] The first end face teeth and the second end face teeth cooperate with each other to improve the structural stability between the sleeve and the mixing plate and prevent relative movement between the sleeve and the mixing plate. The first end face teeth and the third end face teeth cooperate with each other to improve the structural stability between the fixed sleeve and the mixing plate.

[0033] Furthermore, the mixing plate is provided with arc-shaped holes.

[0034] The mixing effect of the mixing plate is improved by setting arc-shaped holes. Several arc-shaped holes are set and evenly distributed around the axis of the mixing plate.

[0035] The beneficial effects of this application are:

[0036] 1. The first sensor is used to detect the wear condition of the protrusion.

[0037] 2. A second sensor is used to detect wear on the edge of the mixing plate.

[0038] 3. Fix both the mixing disc and the sleeve onto the mixing shaft. Different sizes of sleeves can be used to set different numbers of mixing discs on the mixing shaft, which can be used for grinding machines with different requirements. Attached Figure Description

[0045] The embodiments of this application are described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.

[0046] Example 1:

[0047] like Figure 1 , Figure 2 , Figure 3 As shown in the figure, this application provides a mixing disc structure for a grinding machine, including:
