Abstract
The utility model provides a wet type middle speed grinding mill which comprises a feeding pipe, a driving unit, a grinding plate unit, a grinding roller unit and a material extract pipe. An overflow ring which has an adjustable height is held and arranged at the edge of the outside diameter of the grinding plate unit. The driving unit drives the grinding plate unit to revolve and the grinding roller unit above the grinding plate unit is driven by the frictional force of the material on the grinding plate unit, so as to grind the material on the grinding plate unit where the feeding pipe is right above from which the material and water are poured onto the center of the grinding plate unit. The adoption of the wet type middle speed grinding mill in the utility model has the advantages of that the utility model is highly efficient, energy-saving, safe, environment protective and low in production cost, and good fineness of the product.
Description
Technical field:
The utility model relates to a kind of middling speed grinding machine that is applied to mine, electric power, chemical industry, building material industry, particularly relates to a kind of wet type middling speed grinding machine that adopts wet work.
Background technology:
At present, the middling speed grinding machine that is applied to mine, electric power, chemical industry, building material industry all is a dry operation, and with the compressed air delivery material, separator sorts the product grade.This middling speed grinding machine is with its mill efficiency height, to operating environment high request and being widely used too not.But dry method middling speed grinding machine exists a lot of defectives, as: need to be equipped with huge, complicated equipments such as hot blast, explosion-protection equipment, sealing environment protecting system and blower fan, drying medium generator, separator, inert gas source or steam for fire xtinguishing, in addition, the complete machine size of dry type middling speed grinding machine and weight are all very big, and be difficult to produce the thinner product of particle, dust pollution is serious, and power consumption is high, and production cost is higher.
Summary of the invention:
The purpose of this utility model is exactly for a kind of deficiency that overcomes dry type middling speed grinding machine is provided, energy-efficient, safety and environmental protection, simple in structure, wet type middling speed grinding machine that applicability is stronger.
The purpose of this utility model is achieved in that removes the blower fan of original conventional dry type middling speed grinding machine, spout ring, separator and auxiliary equipment, grinding machine top only keeps feed pipe, the bottom keeps driving section, mill portion, grinding roller portion, drainage conduit, simultaneously, fix one and have certain altitude and adjustable for height overflow ring closing at mill external diameter edge, and make the seal form of mill portion, grinding roller portion into closed performance better hydrolock sealing.Like this, the driving section drives mill portion and rotates, the grinding roller portion of mill portion top against with mill portion on the frictional force servo-actuated of material, roll the material in the mill portion, feed pipe is directly over mill portion, material and water are added to central authorities of mill portion from feed pipe.During the wet type middling speed quick mill work that provides when the utility model, at first material and water are added according to the feed pipe of technological requirement by the loam cake center, material and water fall into mill central authorities, and formation " material awl ", under the drive of mill portion motion, enter the district that mills, form the certain thickness bed of material, the mill portion that the bed of material is moved mutually, grinding roller portion grinding become the slip of expection granularity and concentration.The overflow ring surrounds mill portion in the flow field of a solid phase, liquid phase two phase flow, in the flow field, material particles distributes by levels, form " hierarchical layer ", the thin lower coarse in upper strata, the fine fraction particle overflows grinding machine with water from overflow ring upper edge because of being suspended in the upper strata, the coarse fraction particle is because of being deposited in lower floor, falls back to again on the mill by grinding once more.The slip that overflows falls into the chamber that gathers materials, and is scraped discharge gate by the material scraping plate of servo-actuated and draws off, select qualified products after, nonconforming salvage stores is led and is got back to charging aperture and reface.
The wet type middling speed grinding machine that adopts the utility model to provide is compared with conventional dry type middling speed grinding machine, and advantage such as have energy-efficient, safety and environmental protection, production cost is low, and product granularity is thin has remedied the deficiency that present dry type middling speed grinding machine exists.
Description of drawings:
Below, in conjunction with the accompanying drawings the utility model is described further:
Fig. 1 is the structural representation of the utility model wet type middling speed grinding machine.
Fig. 2 is the mill portion schematic diagram of the utility model wet type middling speed grinding machine.
Fig. 3 is conventional dry type middling speed grinding machine structural representation.
The specific embodiment:
As seen from Figure 1, the wet type middling speed grinding machine that the utility model provides is that the blower fan of conventional middling speed grinding machine among Fig. 3, spout ring, separator and auxiliary equipment are removed, grinding machine top only keeps feed pipe 1, the bottom keeps driving section 2, mill portion 3, grinding roller portion 4, simultaneously, fix one and have certain altitude and adjustable for height overflow ring 5 closing at mill portion 3 external diameter edges, and make the seal form of mill portion 3 and grinding roller portion 4 into sealing property better hydrolock sealing.Driving section 2 drives mill portions 3 and rotates, the grinding roller portion 4 of mill portion 3 tops against with mill portion 3 on the frictional force servo-actuated of material, roll the material in the mill portion 3, feed pipe 1 is directly over mill portion 3, material and water are given to 3 central authorities of mill portion from feed pipe 1.
As seen from Figure 2, during the wet type middling speed quick mill work that provides when the utility model, material and water are added from feed pipe 1 according to technological requirement, material and water fall into the central authorities of mill portion 3, form " material awl ", under the drive that mill portion rotates, enter the district that mills, form the certain thickness bed of material, the mill portion 3 that the bed of material is moved mutually, grinding roller portion 4 grindings become the slip of expection granularity and concentration.Overflow ring 5 surrounds mill portion 3 in the flow field of the two phase flow of a solid phase, liquid phase, in the flow field, material particles is under the synergy of abrasive power, centrifugal force, suspending power, settling capacity, keep a suitable pulp density, the fine fraction particle is because of being suspended in the upper strata, overflow grinding machine with water from overflow ring 5 upper edges, a coarse fraction level is because of being deposited in lower floor, falls again in the mill portion 3 by grinding once more.The slip that overflows falls into the chamber that gathers materials, and is scraped drainage conduit by the scraper plate of servo-actuated and draws off.After selecting qualified products, nonconforming salvage stores is led and is got back to charging aperture 1 and reface.For adapting to the product of grinding different grain size grade, overflow ring 5 can be made the shape of soil along the band sieve aperture.
