The utility model relates to a dispersing and grinding cylinder device for a sand mill, which is mainly composed of a cylinder body component 1, a main shaft 2, a monolayer enclosed centrifugal turbine 3, a charge pipe 4, a cylinder body end cover 5, a discharge seat 6, duplex enclosed centrifugal turbines 8 and a cylindrical pin 9. One end of the main shaft 2 passes through the discharge seat 6 and extends into the cylinder body component 1, and the cylinder body end cover 5 and the discharge seat 6 are respectively installed on both ends of the cylinder body component 1. One end of the charge pipe 4 passes through the cylinder body end cover 5 and is communicated with the inner chamber of the cylinder body component 1, the monolayer enclosed centrifugal turbine 3 and the two duplex enclosed centrifugal turbines 8 are installed on the main shaft 2. Sand return directed oblique holes 7 which are symmetrical by taking the shaft center as a reference are respectively arranged on the monolayer enclosed centrifugal turbine 3 and the duplex enclosed centrifugal turbines 8. With the same requirement for the fineness of products, the utility model greatly decreases the grinding frequency, improves the production efficiency, saves the energy consumption, effectively avoids the block of grinding media near the discharge end at the inner chamber of the cylinder body component, and reduces the operating pressure and the operating temperature of the entire device.

Description

Sand mill dispersion grinding cartridge is described

Technical field

The utility model relates to a kind of parts of sand mill, in particular for the solid, liquid mixture being carried out the sand mill dispersion grinding cartridge of efficient solid, liquid phase dispersion grinding.

Background technology

Sand mill is a kind of a kind of equipment that is widely used in wet method hyperfine abrasive processing in the industries such as paint, printing ink, dyestuff, cosmetics, agricultural chemicals, medicine, papermaking, magnetic, ferrite.Its operation principle is to pump in the dispersion grinding cylindrical shell with the slip that pump will dilute after the stirring in advance, the dispersion stirring parts that main shaft drives in the dispersion grinding cylindrical shell is done rotation at a high speed, mechanical energy is passed to wherein abrasive media, it is moved in the dispersion grinding cylindrical shell, the product slip is done mandatory shearing grind, make product reach the fineness or the color saturation of regulation.Sand mill adopts disc type or two kinds of structures of excellent pin formula usually with the dispersion stirring parts in the dispersion grinding cartridge both at home and abroad at present, disperse stirring parts in the subrange of its rotation, to stir to product slip and abrasive media, the axial circulation exchange of abrasive media in the dispersion grinding cylindrical shell is insufficient, cause discharging to separate the obstruction of port easily, operating pressure and operating temperature are higher, for making product reach the fineness requirement of regulation, needed milling time is longer, production efficiency is low, the energy consumption height.

The utility model content

The purpose of this utility model provides a kind of sand mill dispersion grinding cartridge, and is low with the grinding efficiency that solves traditional sand mill, the problem that energy consumption is high.

For this reason, sand mill described in the utility model dispersion grinding cartridge, comprise cylinder assembly, main shaft, feed pipe, cylindrical shell end cap and discharging seat, one end of main shaft stretches in the cylinder assembly after passing the discharging seat, cylindrical shell end cap and discharging seat are installed in the two ends of cylinder assembly respectively, one end of feed pipe communicates with the cylinder assembly inner chamber after passing the cylindrical shell end cap, the dispersion stirring parts is housed on the main shaft, this dispersion stirring parts is the closed centrifugal turbine, and is provided with the sand return directed inclined hole about the axle center symmetry on this closed centrifugal turbine.

Above-mentioned closed centrifugal turbine is made up of an individual layer closed centrifugal turbine and two duplex closed centrifugal turbines, individual layer closed centrifugal turbine is positioned at the feed end near cylinder assembly, and individual layer closed centrifugal turbine and duplex closed centrifugal turbine all are installed on the main shaft by straight pin.

Replace traditional disc type or excellent pin formula to disperse stirring parts with the closed centrifugal turbine in the utility model, because the closed centrifugal turbine is distributed with a lot of blades on circumference, when rotating at a high speed, mechanical energy can be passed to abrasive media to greatest extent, make the product slip in the unit interval, obtain maximum shearing and disperse.In addition, owing to also be provided with the sand return directed inclined hole on the closed centrifugal turbine, make it have from suction and axially promote function abrasive media, product slip and abrasive media in the cylinder assembly inner chamber, carry out complicated radially, the circumferential and axial circulation, make the product slip obtain optimized dispersion and shear.

The beneficial effects of the utility model are: under the equal fineness requirement condition of product, can significantly reduce the grinding number of times, improve production efficiency, save energy consumption, and can effectively avoid near the obstruction of abrasive media cylinder assembly inner chamber discharge end, reduce the operating pressure and the operating temperature of whole device.
