Abstract
A vertical grinding device with a damping buffer comprises a main drive system. A grinding disc is arranged on the main drive system; a grinding roller matched with the grinding disc is arranged on the surface of the grinding disc; the grinding roller and a hydraulic loading device are mutually connected; and a damping buffer is arranged between the hydraulic loading device 4 and a fixed base. The main drive system drives the grinding disc to rotate, the material is extruded, sheared and shattered under centrifugal force when subject to the pressure of the hydraulic loading device, and when the non-uniformity of the material increases or the property of the material changes, owe to the advantages per se, the damping buffer absorbs vibration energy to reduce vibration of the grinding machine. The utility model has the advantages of good stability of the vibration reduction equipment, large energy-absorbing ratio and strong adaptation to different materials.
Description
Technical field
The utility model relates to the grinding machine field, particularly a kind of vertical milling equipment with damping buffer.
Background technology
Domestic existing Vertical Mill milling equipment core component is made up of grinding roller, mill, main transmission, hydraulic loading system and high-efficient powder concentrator.Operation principle is as follows: after material is fallen mill central authorities, under action of centrifugal force, get rid of to the mill edge and be subjected to the extruding, shearing, percussion of grinding roller and grinding, material after the pulverizing overflows from the edge of mill, the hot blast that part is made progress at a high speed from air guide ring takes up oven dry, through the powder concentrator effect, qualified fine powder goes out mill with air-flow from grinding machine top, be product.Because existing grinding machine does not design buffer unit, what have just reduces vibration by the dish spring, and it is little that it absorbs vibrational energy, poor to the adaptive capacity of material, often causes unnecessary shutdown because of vibration.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of vertical milling equipment with damping buffer, adopt the damping buffer vibration damping, have the advantage that the vibration damping stabilization of equipment performance is good, the energy-absorbing ratio is big, efficient is high, strong to the different material adaptive capacity.
In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of vertical milling equipment with damping buffer, comprise main transmission 1, main transmission 1 is provided with mill 2, the surface of mill 2 is suitable with it grinding rollers 3, grinding roller 3 is connected with hydraulic loading device 4, disposes damping buffer 5 between hydraulic loading device 4 and the immobilizing foundation.
Described damping buffer 5 is a kind of semifluid macromolecular compounds.
Described damping buffer 5 materials are polyethylene.
Because the utility model has increased damping buffer 5, damping buffer 5 is a kind of semifluid macromolecular compounds, has high viscosity, viscosity reaches 20000000cSt, excellent heat endurance is arranged, it possesses the double effects of spring and hydraulic damper, so energy-absorbing can reduce the vibration of whole milling equipment than big.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model technology is described in detail.
With reference to accompanying drawing, a kind of vertical milling equipment with damping buffer, comprise main transmission 1, main transmission 1 is provided with mill 2, the surface of mill 2 is suitable with it grinding rollers 3, and grinding roller 3 is connected with hydraulic loading device 4, disposes damping buffer 5 between hydraulic loading device 4 and the immobilizing foundation, damping buffer 5 is a kind of semifluid macromolecular compounds, as polyethylene.Have high viscosity, viscosity reaches 20000000cSt, and excellent heat endurance is arranged, and possesses the double effects of spring and hydraulic damper.
Operation principle of the present utility model is: main transmission 1 drives mill 2 and rotates, material is subjected to the pressure of hydraulic loading device 4, extruding under centrifugal action, shearing, pulverizing, brought into the powder concentrator separation and be collected as finished product by thermal current at last, when the inhomogeneities of material increases or character when changing, damping buffer 5 reduces the grinding machine vibration because itself advantage can absorb vibrational energy.
