Description

Wind is swept annular grinder

Technical field

The present invention relates to a kind of grinding device, be meant that further a kind of wind sweeps annular grinder.

Background technology

In the prior art, selecting powder equipment all is by wind-force selected thickness mixed material to be carried to reach from bottom to top to select the powder purpose.Annular grinder be by wind-force radially repeatedly selection by winnowing reach it and select the powder purpose.Because material is bigger to the main abrasive media loss of grinder, as grinding ring wearing and tearing easily, and installs and change the operating efficiency that inconvenience etc. has directly influenced grinder during the annular grinder grinding material, have drawbacks such as difficult in maintenance.

Summary of the invention

The technical problem to be solved in the present invention is, at the deficiencies in the prior art, propose a kind of wind and sweep annular grinder, it is a multilayer grinding multilayer selection by winnowing, and powder is even, thickness is adjustable, and the rotation of stone roller ring is flexible, automatic compensate for wear, increase the service life, the installation and maintenance of open-type structure are more convenient simple, make the complete machine operational efficiency higher, more reliable.

Technical solution of the present invention is, it is feed hopper and the vertical chassis of coarse fodder discharge bucket is arranged at the bottom that described wind is swept the annular grinder top, be contained at least two rotating disks are housed on the main shaft in the cabinet vertically successively, described rotating disk periphery be equipped with a plurality of can be around the stone roller ring of its vertical pivot rotation and every grind the corresponding cabinet inwall position of ring be equipped with corresponding in lining ring, described main shaft bottom is installed on the base and belt pulley and flying wheel are equipped with in the main shaft bottom, its design feature is, the cabinet sidewall periphery is provided with outer case and constitutes the bottom thus is the fines collecting chamber of fines discharge bucket, the air-supply joint is housed at the main shaft top and its air channel is communicated with the tracheae that the main shaft side also distributes vertically, described tracheae has wind pushing hole and has through hole on the cabinet sidewall of correspondence therewith at the position between adjacent two rotating disks, and described through hole is positioned at fines collecting chamber one side and is provided with the bias plate.

Below make and further specifying.

Referring to Fig. 1, the present invention includes the top and be feed hopper 1 and the vertical chassis 10 of coarse fodder discharge bucket 20 is arranged at the bottom, be contained at least two rotating disks 3 are housed on the main shaft 2 in the cabinet 10 vertically successively, described rotating disk 3 peripheries be equipped with a plurality of can be around the stone roller ring 7 of its vertical pivot rotation and every cabinet 10 inwall position of grinding ring 7 correspondences be equipped with corresponding in lining ring 4, described main shaft 2 bottoms are installed on the base 12 and belt pulley 23 and flying wheel 24 are equipped with in main shaft 2 bottoms, its design feature is, cabinet 10 sidewall periphery are provided with outer case 22 and constitute the bottom thus is the fines collecting chamber 9 of fines discharge bucket 13, air-supply joint 5 is housed at main shaft 2 tops and its air channel is communicated with the tracheae 6 that main shaft 2 sides also distribute vertically, described tracheae 6 has wind pushing hole 21 and has through hole 8 on cabinet 10 sidewalls of correspondence therewith at the position between adjacent two rotating disks 3, and described through hole 8 is positioned at fines collecting chamber 9 one sides and is provided with bias plate 11.Described cabinet 10 can be made as the interlayer casing of piecemeal, and this cabinet 10 can pass through pull bar 19 switch casing easily, during unlatching, just moves on base plate 20 by pull bar 19 cabinets 10, thereby rotor portion 18 is exposed, and is convenient for changing stone roller ring 7 and safeguards annular grinder.And the interior lining ring 4 that is contained on the cabinet 10 is also taked and 10 corresponding numbers of cabinet, the replacing (referring to Fig. 3) of convenient interior lining ring 4.

As shown in Figure 2, a kind of example structure of described stone roller ring 7 is, it comprises two slide blocks 14 up and down, and slide block 14 is tightly connected with interior ring 16, has rolling bearing 17 to link to each other between slide block 14 and the interior ring 16, and there is outer shroud 15 closely connection with it the outside of interior ring 16.Outer shroud 15 adopts anti-friction materials to make, and outer shroud 15 is heat expansion assemblings with interior ring 16, and therefore as long as outer shroud 15 does not rupture and just can fully use, automatic compensate for wear and can be vented to slide block 14 inside increases the service life.

Referring to Fig. 1, interior lining ring 4 and rotating disk 3 adopt pagoda type multilayer crushed work cavity configuration, and promptly the internal diameter of the diameter of a rotating disk 3 of lower floor and corresponding interior lining ring 4 wants big than disk diameter above it and corresponding interior lining ring internal diameter, that is adopts up-small and down-big structure.When material was fallen certain one deck from top to bottom through grinding ring, rotating disk 3 can spread the material branch on the inwall of next interior lining ring 4 once more, reduces the decrease speed of material, increases the probability that material is pulverized simultaneously.

Referring to Fig. 3, casing 10 can be designed to be formed by the part box body combinations more than two or two.

Structural principle of the present invention is (as shown in Figure 1), drive every layer of rotating disk 3 and grind ring 7 rotation simultaneously by main shaft 2, the grinding charge material that entered by feed hopper 1 this moment is evenly divided to spread between interior lining ring 4 and the rotating disk 3, grinding ring 7 is subjected to the frictional resistance of grinding charge material and liner to begin rotation, be subjected to the impact of ring 7 grinding by abrasive material, roll and shear and pulverize, compress wind radial spray by air-supply joint 5 and tracheae 6 is to cabinet 10, when pulverized successively thickness mixture falls, be rotated selection by winnowing and go out qualified fine powder, the fine powder of selecting is through through hole 8 and enter fines collecting chamber 9, for preventing in fines collecting chamber 9, to produce whirlwind with the compress wind of fine powder, in through hole 8 outsides bias plate 11 is arranged, block whirlwind and enter fines collecting chamber 9, thereby fine powder is moved downward again discharges through fines discharge bucket 13, all the other thicker materials are then fallen into down one deck and are ground ring 7 grindings, so grinding of circulation, selection by winnowing, the meal after basecoat stone roller ring comminuting matter is by selection by winnowing is discharged through coarse fodder discharge bucket 20.

As known from the above, the present invention sweeps annular grinder for a kind of wind, and it is a multilayer grinding multilayer selection by winnowing, and powder is even, thickness is adjustable, and the rotation of stone roller ring is flexible, automatically compensate for wear, increase the service life, the installation and maintenance of open-type structure are more convenient simple, make the complete machine operational efficiency higher, more reliable.
