Description

The basket type sand mill lapping device

Technical field

The utility model relates to a kind of industries such as chemical industry, coating, printing ink, pharmacy that are used for, to the milling apparatus that liquid material grinds, and the vitals on particularly a kind of basket type sand mill-basket type sand mill lapping device.

Background technology

In the existing basket coating milling apparatus, motor, connecting rod all are to be connected on the fixed mount, the basket body is suspending in midair motionless, when pump dise pumps into material in the basket body, the abrasive body high speed rotating in the driven by motor basket body drives the abrasive granule of filling in the basket body, material is ground, add the peptizaiton of dispersion impeller, sand mill just can be to circulate refinement processing of material, until meeting the requirements of fineness.

Adopt axial seal between seal receptacle, screen tray and the main shaft of the milling bar lower end of existing basket type sand mill, the installation difficulty height, be consumable accessory also because of milling bar, can produce clearance gap because of wearing and tearing in rotation and between actionless seal receptacle, the mill ball fragment that is crashed easily enters in the seal receptacle between seam, destroys axial seal, and wear spindle, therefore need often maintenance, transposing part, increase inconvenience to the user.

Patent No. CN200420084216.2 " a kind of basket sand milling coating milling apparatus " only is modified into steel pipe with four steel connecting rods on the hanging basket, has guaranteed the sufficient intensity of hanging basket suspention, has reduced cost.Cover design fan-shaped opening is arranged last in addition, be convenient to change the operation of grinding pearl, and on fan-shaped opening, use the screw-driving capping, reach the purpose of sealing opening.But in this patent, rotor is installed on the main shaft with the trip bolt of two symmetries, and be positioned at the below of hanging basket loam cake, agitator is positioned at the below of rotor, the trip bolt that is still with two symmetries is installed on the main shaft, rotor, agitator all are the part that rotates at a high speed, and time long back screw is easily loosening, so the fixed form of this structure is unreliable.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of basket type sand mill lapping device is provided, the structure of existing lapping device is improved, reduced the maintenance and the replacing of wear-out part, and be convenient to install, both improve sealing effectiveness, prolonged service life again, reduced production cost.

The technical scheme in the invention for solving the above technical problem is: the lapping device of basket grinder, comprise the pump dise that is connected on the main shaft, last cover, milling bar, and be installed in the basket body, the loam cake of the upper surface fixed band connecting rod of basket body, the screen tray of fixed band seal receptacle on the lower surface of basket body, the dispersion impeller of the terminal fixed band cover clamp of main shaft, also be connected with spring and spring positioning ring on the described pump dise, spring, spring positioning ring are installed on the main shaft, and the lower surface of described milling bar and the upper surface of seal receptacle are sealed and matched all the time in the spring action lower surface.

Compared with prior art, advantage of the present utility model is: fixed form and seal form to existing basket type sand mill lapping device are improved, wearing and tearing between main shaft and screen tray, seal receptacle are big, difficult between centers sealing of installing, be improved to the end face seal between milling bar and seal receptacle, and increase spring to remain the end face seal of milling bar lower surface, also can constantly compensate the wearing and tearing between milling bar and seal receptacle, good sealing effect, reduced the replacing of wear-out part, prolong service life, reduced production cost.Also adopted simultaneously to change the shape that main shaft cooperates the cross section, to change over both sides from circular shaft be the plane, and both sides are the shaft section of arcwall face, and with pump dise and milling bar on the through hole tight fit that is complementary, it is not had relatively rotates, convenient fixing, reliable; Filter opening on the screen tray changes the strip through hole into, has both made things convenient for the liquid material to spill and the difficult obstruction of filter opening; Connecting rod adopts connecting screw rod, is convenient to dismounting with being threaded, regulates and repeatedly uses.

The structural representation of Fig. 2, pump dise.

The structural representation of Fig. 3, screen tray.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

With vulnerable parts such as the milling bar 4 of high speed rotating, pump dises 3, adopt high abrasion resisting material to make, to increase the service life.

Connecting rod adopts the threaded connecting screw rod 12 of an end, and loam cake 11 is by connecting screw rod 12 location.

Basket body 2 inwall top edges have four uniform flanges, screw is arranged in the middle of the flange, and four connecting screw rods 12 pass the screw on loam cake 11 and the flange, with nut loam cake 11 are fixed on the basket body 2, the connecting screw rod 12 of this kind structure is convenient to dismounting, installs, is regulated, and is repeatedly used.

Seal receptacle 8 is pegged graft and is fixed in the hole in the middle of the screen tray 5, and the filter opening 5-1 on the screen tray 5 be the strip through hole of distribution according to certain rules, is convenient to that the liquid material spills and filter opening is difficult for blocked.

Uniform prerotation vane 3-2 is arranged, neutral gear place fixing spring 10 and spring positioning ring 13 in the middle of each prerotation vane on the pump dise 3.In the middle of the bottom surface through hole 3-1, shape of through holes being arranged is that the two sides is the plane, and the two sides is an arc surface.

Main shaft 1 lower end pass successively loam cake 11, spring positioning ring 13, spring 10, pump dise 3, on overlap 9, milling bar 4, seal receptacle 8, screen tray 5, stretch out outside the screen tray.Spring positioning ring 13 is with the shaft shoulder on the main shaft 1 location, the through hole 3-1 on the pump dise 3 corresponding with the through hole on last cover 9, the milling bar 4 (figure draws), also with main shaft 1 on the two sides be the plane, the two sides is the shaft section tight fit that arc surface is complementary.

Screen tray 5 is fixed by bolts on the lower surface of basket body 2.

Square hole tight fit on the end of main shaft 1 and the dispersion impeller 6, and dispersion impeller 6 is fixed in the screw of main shaft 1 lower end with cover clamp 7, bolt, the upper end of main shaft 1 is connected motor (figure draws) through belt pulley with the V-belt.

During use, pump dise 3 pumps into liquid coating in the basket body 2, whole lapping device is immersed in the liquid material, drive pump dise 3, milling bar 4 basket body 2 at a high speed rotation through belt pulley and V-belt by main shaft 1 by motor, the abrasive granule of filling clashes into mutually, shears material is ground refinement in milling bar and the basket body, the filter opening 5-1 of material after the grinding on screen tray 5 flows out the basket body, the dispersion impeller 6 that is driven by main shaft 1 is broken up the material that flows out at last, finish the once grinding of material, material is by continuous circular grinding, until meeting the requirements of fineness.In rotating whipping process, spring 10 is pressed on the seal receptacle 8 by pump dise 3, milling bar 4 always, make seal receptacle 8 and milling bar 4 remain plane contact, form end face seal, though milling bar 4 can wear and tear through the high speed rotary end surface, but there is spring 10 to make axial clearance compensation, guaranteed sealing effectiveness.
