Description

Technical Field

[0001] The utility model relates to the field of ball mills, in particular to a low-noise and low-vibration dry mill. Background Art

[0002] In the field of ball mills, especially in the fields of precision grinding such as ceramics, glass, building materials, pharmaceuticals, spectral analysis, as well as in the fields of geological mining and nuclear industry research, the application of ball mills is particularly important. However, most of the ball mills on the market currently have certain technical bottlenecks and problems in operation and use.

[0003] Traditional ball mills rely mainly on the operator's experience for settings during operation, which not only requires the operator to have rich practical experience, but also increases the difficulty and uncertainty of operation. More importantly, this experience-dependent operation mode often leads to the sedimentation or agglomeration of the slurry during the grinding process, resulting in unsatisfactory grinding results and even requiring secondary ball milling, which will undoubtedly seriously affect the production or experimental progress and reduce work efficiency. In addition, the existing ball mills generate large noise and vibration during operation, which not only worsens the working environment of the operators, but may also have adverse effects on the stability and service life of the equipment. Long-term operation in a harsh working environment is also a challenge to the physical and mental health of the operators.

[0004] Therefore, there is an urgent need for a new type of ball mill equipment that can solve the above problems and improve grinding efficiency and working environment. Utility Model Content

[0005] The purpose of the utility model is to provide a low-noise and low-vibration dry grinder, which can effectively reduce the noise and vibration generated by the equipment during operation, thereby improving the working environment of the operators and improving production efficiency.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is to design a low-noise and low-vibration dry grinder, including a shell 1, a grinding pot 2, a driver 3, a transmission shaft 4 and a silencer spring 5. The grinding pot 2 is arranged inside the shell 1 and is connected to the shell 1 through a sliding device. The lower part of the grinding pot 2 is connected to the transmission shaft 4, and the lower part of the transmission shaft 4 is connected to the driver 3. The driver 3 rotates through the transmission shaft 4 to drive the grinding pot 2 to rotate for grinding operations. The silencer spring 5 is arranged between the lower part of the grinding pot 2 and the shell 1. The silencer spring 5 is used to absorb and alleviate the vibration and sound generated when the grinding pot 2 is working.

[0007] Preferably, the grinding pot 2 is made of corundum, agate or zirconium oxide toughened alumina.

[0008] Preferably, the volume of the grinding pot 2 is 500 to 5000 mL.

[0009] Preferably, the rotation speed of the grinding pot 2 is 20 to 80 rpm / min.

[0010] The advantages and beneficial effects of the utility model are as follows: a low-noise and low-vibration dry grinder designed by the utility model can effectively absorb and alleviate the vibration and sound generated by the grinding pot when it is working by arranging a silencer spring between the lower part of the grinding pot and the shell, which significantly improves the working environment of the operators and reduces noise pollution; the grinding pot is made of high-quality materials such as corundum, agate or zirconium oxide toughened alumina, which not only ensures the grinding effect, but also improves the durability and service life of the equipment.

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 those skilled in the art without creative work are within the scope of protection of the utility model. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model. In the utility model, unless otherwise stated, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0015] like Figure 1 As shown, a low-noise and low-vibration dry grinder mainly includes a shell 1, a grinding pot 2, a driver 3, a transmission shaft 4 and a silencer spring 5.

[0016] The housing 1 serves as the external protective structure of the entire device, providing a closed and safe working environment for the internal components. It has a strong structural strength and can withstand the vibration and stress generated when the internal components are working.

[0017] The grinding pot 2 is placed inside the housing 1 and is the main place for grinding. The material is selected to be high-quality material, such as corundum, agate or zirconium oxide toughened alumina, etc., to ensure grinding effect and durability. The grinding pot 2 has a moderate volume capacity, usually between 500 and 5000 mL, to meet the grinding needs of different scales.

[0018] The driver 3 serves as a power source for the equipment and performs grinding operations by rotating the transmission shaft 4 and the grinding pot 2.

[0019] The transmission shaft 4 connects the grinding pot 2 and the driver 3 to transmit the driving force. The transmission shaft 4 has high strength to withstand the high-strength torque during the grinding process.

[0020] The silencer spring 5 is installed between the bottom of the grinding pot 2 and the housing 1. The main function of the silencer spring 5 is to absorb and alleviate the vibration and sound generated when the grinding pot 2 is working, so as to create a more comfortable working environment for the operator.

[0021] The specific usage is as follows:

[0022] First, make sure the dry grinder is installed on a level and solid surface, and check the safety of the power supply and cables. Then, select the appropriate grinding tool according to the grinding requirements and make sure it is installed firmly.

[0023] After the power is turned on, the speed of the equipment is set according to the material of the object and the desired grinding effect, usually between 20 and 80 rpm / min, and the dry grinder is started for grinding. During the grinding process, the grinding effect needs to be observed at all times so that timely adjustments can be made.

[0024] After grinding, disconnect the power supply first, and then thoroughly clean the work area, especially important parts such as silencer springs and sliding devices, to ensure that the equipment can operate normally the next time it is used. In addition, in order to extend the life of the equipment and improve efficiency, the worn parts should be checked and replaced regularly, and the overall cleanliness and dryness of the equipment should be kept.
