Description

Technical Field

[0001] The utility model relates to the technical field of sand mill bases, in particular to a sand mill frame and sand mill equipment thereof. Background Art

[0002] In the prior art, sand mills or ball mills are assembled as a whole, and grinding media such as ball media and rod media are generally arranged inside. In some cases, irregular shapes such as frustum, cylindrical balls, and short round rods are used, which are called special-shaped media.

[0003] Sand mill, also known as bead mill, is mainly used for wet grinding of chemical liquid products. According to its performance, it can be roughly divided into horizontal sand mill, basket sand mill, vertical sand mill, etc.

[0004] It mainly consists of a machine body, a grinding drum, a sanding disc (paddle), grinding media, a motor, and a feed pump. The feed speed is controlled by the feed pump. The grinding media of this equipment are generally divided into zirconia beads, glass beads, zirconium silicate beads, etc.

[0005] Existing sand mills generally rely on a drive motor to drive the rotating shaft and grinding parts to rotate, and cooperate with the grinding medium to grind the material. During the grinding process, when feeding, due to the high grinding precision and the particle size of the material itself, the top may burst, and then blockage may occur.

[0006] At the same time, when grinding, if the size of the material itself is too large, it will also increase the heat generated by the grinding device, increase losses, and shorten the service life of the device.

[0007] The above processes may lead to reduced grinding efficiency and reduced fineness of material grinding, which will affect the service life of the machine and bring economic losses. Utility Model Content

[0010] The beneficial effects of the present invention are as follows: when grinding materials, the weight of the frame itself is changed by adjusting the components, and then the output power of the material grinding is matched, the natural frequency is changed, and resonance is achieved, so that the device vibrates continuously during the feeding process to break up the agglomerated materials and avoid the occurrence of top bulging. At the same time, during the grinding process, the internal materials are ground more evenly through vibration.

[0016] Furthermore, the limiting member includes a limiting plate and a rubber plate, the rubber plate is fixedly assembled on the inner wall of the lower end of the rectangular groove, and the limiting plate is assembled on the rubber plate.

[0017] The above technical solution sets a limit plate and a rubber plate. When the counterweight column needs to be screwed onto the frame, the rubber plate is compressed so that the connecting column equipped with the counterweight column can enter the rectangular groove of the frame and be fixedly assembled inside the frame.

[0018] Furthermore, the limiting plate is provided with a plurality of first threaded holes spaced apart along its length direction, and the upper inner wall of the rectangular groove is provided with a plurality of second threaded holes corresponding one-to-one to the first threaded holes, and the upper and lower ends of the connecting column are screwed into the first threaded hole and the second threaded hole through two threaded columns.

[0019] The above technical solution provides a first threaded hole on the rectangular groove and provides a second threaded hole on the limiting plate corresponding to the lower end of the first threaded hole, thereby enabling the counterweight to be conveniently assembled in the rectangular groove.

[0020] Furthermore, the elastic member includes a base with a cavity inside, a moving block, a spring bar and a support block. The moving block slides up and down in the cavity.

An adjustment component is provided inside the frame 1 for adjusting the weight of the frame 1, thereby changing the natural frequency of the frame 1.

[0037] The working principle is: when grinding materials, the adjustment component is changed according to the power of grinding the materials, thereby changing the weight of the frame 1 itself and the natural frequency of the frame 1, so that the device can vibrate according to the power of material grinding, which is convenient for the subsequent material feeding process.

[0038] The above technical solution can change the weight of the frame 1 itself by adjusting the components when grinding the material, and then change its natural frequency to achieve resonance in accordance with the output power of the material grinding, so that the device can vibrate continuously during the feeding process to break up the agglomerated materials and avoid the occurrence of roof bursting. At the same time, during the grinding process, the internal materials can be ground more evenly through vibration.

[0041] The above technical solution changes the weight of the frame 1 itself by selecting the number of counterweights 3 according to the output power of the device and installing them on the frame 1, so as to change its natural frequency so that it can resonate with the vibration frequency of the device motor when it is operating, thereby facilitating feeding.

When the thread is screwed in, as the threaded column 33 continues to be screwed into the inner wall of the upper end of the rectangular groove 2 and the limit plate 4, the limit plate 4 rebounds, which improves the convenience of assembling the counterweight 3.

[0047] The above technical solution sets a limit plate 4 and a rubber plate 8. When the counterweight column 32 needs to be screwed onto the frame 1, the rubber plate 8 is compressed so that the connecting column 31 equipped with the counterweight column 32 can enter the rectangular groove 2 of the frame 1 and be fixedly assembled inside the frame 1.
