Description

technical field [0001] The invention belongs to the technical field of solid-liquid separation, and relates to a vibrating centrifuge, in particular to a horizontal vibrating centrifuge. Background technique [0002] Horizontal vibrating centrifuge is the key equipment for dehydration of materials with particle size less than 50mm. Compared with vertical scraper discharge centrifuge, it has the advantages of less initial investment, small space occupation, low energy consumption, and long service life of the screen basket. Horizontal vibrating centrifuges are widely used in energy, metallurgy, ceramics, building materials, chemical and other industries. The horizontal vibrating centrifuge currently used has the following deficiencies: [0003] 1. The sealing structure of the box of the vibrating centrifuge is often sealed with seals. Due to the relatively high speed of the spindle and the large amount of axial activity, compared with other equipment, the wear of the seals i...

Problems solved by technology

For the commonly used bearing box lubricating oil circuit, please refer to image 3 , but because the oil inlet and outlet of the sleeve are arranged at the pulley end, the lubricating oil cannot circulate effectively in the sleeve, so that the bearing at the screen basket end cannot be fully lubricated and cooled. Compared with the pulley end bearing, the screen basket end bearing The load is greater, the working conditions are worse, and long-term operation will reduce the service life of the screen basket end bearing

[0006] 4. The vibrating centrifuge generally uses a fixed-speed vibrating motor to vibrate. This kind of vibrating mode can only produce a single frequency of vibration. When the external working conditions such as the processing capacity and water content of the material change, the processing effect of the centrifuge cannot reach To achieve the best effect, the potential of the centrifuge cannot be fully utilized, and when it is shut down, the fixed-frequency centrifuge will have a large lateral swing due to the long shutdown time, which seriously affects the structural strength of the centrifuge and poses a safety hazard

[0007] 5. The vibration box of the centrifuge uses a support frame to support the vibration box, see Figure 4 , and the support frame has a certain height. When the centrifuge vibration box is working, the center of gravity of the entire vibration box and even the entire vibration body is high, and the support frame is easy to deform. The support effect is not only unsatisfactory, but also increases the instability of the centrifuge during operation. At the same time, the centrifuge vibrating box support structure is complicated, and the manufacturing cost is relatively high
