The utility model content
Technical problem to be solved in the utility model is to overcome the deficiency of above-mentioned prior art, a kind of convenient disassembly is provided, improves the dynamic centrifugal discharge system of the disk sander of discharging speed.
The utility model is achieved in that and comprises that front-end and back-end are respectively equipped with discharge nozzle and feed pipe and by the sand cylinder of forward and backward end cap sealing with pass the rotating shaft that rear end cap is positioned at the sand cylinder center, the rotating shaft axially spaced-apart is provided with several abrasive disks that rotate with rotating shaft, the rotating shaft front end is provided with the separator of a separation abrasive media, and separator is connected with discharge nozzle.
The utility model also has following additional technical feature:
Described separator comprises that a rotor and an end stretch into the separator of rotor, and rotor is arranged on roller end, and the separator other end is arranged on the sand cylinder drive end bearing bracket; Described separator is connected with discharge nozzle.
Described rotor comprises two rotating disks that be arranged in parallel, connects by several blades that are disposed on its periphery between two rotating disks; Wherein a rotating disk is fixed on roller end by screw, opens the opening that stretches into for separator on another rotating disk.
Described blade tilts to be installed between two rotating disks along the rotating shaft direction of rotation.
Several through holes have been opened on the described blade.
The dynamic centrifugal discharge system of the disk sander that the utility model provides compared with prior art has following advantage: described rotating shaft front end is provided with a separator, described separator comprises that a rotor and an end stretch into the separator of rotor, rotor is arranged on roller end, the separator other end is arranged on the sand cylinder drive end bearing bracket, convenient when changing or dismantle separator like this, need not dismantle rotating shaft; Rotor is provided with along the blade of rotating shaft direction of rotation inclination, and it can rotate with rotor, can grind once more material at separated region, has further improved grinding precision; Several through holes have also been opened on the blade, abrasive media can will not separate port and stop up accumulating on the blade, make whole grinding cavity radial force, the large tracts of land abrasive disk produces high density energy, the energy balance standard material that abrasive media produces on grinding material has improved discharging speed and grinding efficiency, the resistance that can reduce to rotate simultaneously, alleviate the weight of separator, cut down the consumption of energy.And the separator of this structure can make sand mill by sand cylinder after the discharging of endfeed front end, simpler when operating machines, maintenance is more prone to.
Description of drawings
Fig. 1 is the structural representation of a kind of optimal way of the utility model.
Fig. 2 is the perspective view of the utility model rotor.
The specific embodiment
Referring to Fig. 1 to Fig. 2, a kind of optimal way of the discharge system of disk sander of the present utility model is shown, comprise that front-end and back-end are respectively equipped with discharge nozzle 1 and feed pipe 2 and by the sand cylinder 3 of forward and backward end cap 31,32 sealings with pass the rotating shaft 4 that rear end cap 32 is positioned at the sand cylinder center, described rotating shaft 4 axially spaced-aparts are provided with several abrasive disks 5, abrasive disk 5 can be circular or three eccentric forms, also can be oval-shaped or other irregular shapes.Rotating shaft 4 front ends are provided with the separator of a separation abrasive media, and described separator comprises that a rotor 62 and an end stretch into the separator 61 of rotor, keep certain radial clearance between rotor 62 and the separator 61, so that the abundant separation of abrasive media.Described rotor 62 is arranged on rotating shaft 4 ends, rotates with rotating shaft, and separator 61 other ends are arranged on sand cylinder 3 drive end bearing brackets 31, and separator 61 is connected with discharge nozzle 2.The separator of this structure can need not be dismantled rotating shaft very easily with its dismounting or installation when needs are changed or safeguarded.In implementation process, the size of separator 61 should be mated with the size of sand cylinder 3, just can reach grinding effect preferably.Its optimal way is that the diameter of separator 61 is about and grinds 1/3 of barrel dliameter, and its length is about 1/10 of sand cylinder length.
In the present embodiment, described rotor 62 comprises two rotating disks 63 that be arranged in parallel, connect by several blades 64 that are disposed on its periphery between two rotating disks, blade 64 tilts along the rotating shaft direction of rotation, is turbine type, and it rotates with rotor, blade can grind material once more at separated region, further improved the grinding precision of sand mill, and dynamically the minimum slit of whizzer can reach 0.025mm, so just can select thinner abrasive media (zirconium oxide bead).One rotating disk 63 of rotor 62 is fixed on the end of rotating shaft 4 by screw, utilizes dynamic centrifugation principle can fully separate grinding material and abrasive media; Open the opening 65 that stretches into for separator 61 on another rotating disk 63, must guarantee the center line of separator 61 and the central lines of rotating shaft 4 during installation.Also opened several through holes 66 on the blade 64, can reduce rotational resistance, alleviated the weight of separator, cut down the consumption of energy; And in the process of work, abrasive media can not accumulate on the blade 64 and stop up and separate port, makes that like this abrasive media axial circulation exchange sand cylinder 3 in is more abundant, has reduced sand cylinder 4 interior operating pressure and temperature, shorten milling time, improved discharging speed and grinding efficiency.Because the rotor 62 of separator is installed in an end of rotating shaft 4, separator 61 is installed on the sand cylinder drive end bearing bracket 31, so sand mill can change the mode of traditional preceding endfeed rear end discharging from the discharging of back endfeed front end, make that the operation of sand mill is simpler, maintenance is more prone to.Traditional discharge method causes the interior operating pressure of sand cylinder too high easily, and the mechanical seal life-span is short.Input and output material mode of the present utility model can guarantee that the sand cylinder operating pressure is stable, prolonged mechanical sealing life, and can cooling jacket be set at whole perisporium of sand cylinder and drive end bearing bracket place, and rolling bearing installs rotation cooling bearing device additional in rear end cap, by the further operating temperature that reduces in the sand cylinder of water route circulation, improve the service life and the product quality of machine.
The foregoing description is only for the usefulness that the utility model is described; and be not to be to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technical schemes that are equal to also should belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
