Abstract
The utility model provides an internal cooling device for a sand mill. The internal cooling device for the sand mill comprises a bearing pedestal, a main shaft and a grinding rotary drum arranged at the end of the main shaft. Water conveying pipes communicated are arranged in cavities of the main shaft and the grinding rotary drum. A water conveying cover is formed between the outer wall of the water conveying pipes and the inner walls of the main shaft and the grinding rotary drum. A water inlet and a water outlet are arranged on the bearing pedestal. Materials outside of the main shaft, the grinding rotary drum and the grinding rotary drum are sequentially cooled by cooling water so that the cooling effect is enhanced, and the service life of devices is prolonged. The water conveying cover is internally provided with a spiral water channel so that the water flow rate is reduced, cooling on the material is enhanced, and the characteristics of the material are maintained so that the quality is uniform and reliable.
Description
Technical field
The utility model relates to milling apparatus, is specifically related to a kind of interior cooling device of sand mill.
Background technology
Sand mill is that a kind of high efficiency wet method superfine grinding that is widely used in nonmetallic ore industries such as coating, dyestuff, paint, printing ink, medicine, magnetic, ferrite, photographic film, agricultural chemicals, papermaking and cosmetics disperses machinery; Be in the solid-liquid phase mixture material input cylindrical shell that will utilize after the material pump will pass through the pre-dispersed wettability treatment of mixer; Abrasive media in material and the cylindrical shell is stirred by the disperser of rotation at a high speed together; Thereby make solia particle and abrasive media in the material produce stronger collision, friction, shear action each other, reach the purpose of accelerating levigate particulate and scatter-gather body.
Sand mill mainly is made up of frame, motor, grinding cylinder body, main shaft, bearing block etc., and main shaft places on the bearing block by its rotation of driven by motor, and the front end of main shaft is connected with abrasive roller and places to grind in the cylinder body material is ground and working in dispersion.In order to prolong the useful life of sand mill, prevent that main shaft from damaging, generally main shaft is carried out cooling processing, mainly be that its outside is cooled off with cold oil, use cost height and cooling effect are not ideal.And material and abrasive media are stirred by the abrasive roller of rotation at a high speed together in the grinding cylinder body, its abrasive roller Yin Wendu rising and yielding; In addition, the material of grinding is in the hot environment for a long time, and some labile materials will at high temperature decompose like medicine, agricultural chemicals, and the effective ingredient of grinding finished product reduces, and causes product defective.
The utility model content
The utility model will solve above-mentioned deficiency exactly, the sand mill that provides a kind of inside to cool off, the cooling that has solved abrasive roller and grinding material, the life-span and the grinding material quality of raising equipment.
In order to reach above-mentioned effect; The utility model provides a kind of interior cooling device of sand mill; Comprise bearing block, main shaft and install abrasive roller in spindle nose; Said main shaft is provided with the fortune water pipe that is communicated with the inner chamber of abrasive roller, forms the fortune water jacket between said fortune pipe outer wall and main shaft and the abrasive roller inwall; Said bearing block is provided with water inlet and delivery port.
Said water inlet and fortune cross current, delivery port is communicated with cooling water circulation canal in the formation with the fortune water jacket.
Said abrasive roller inwall is provided with spiral tank.
Water inlet and fortune cross current in the utility model device, delivery port is communicated with the fortune water jacket, and promptly at the inner intake tunnel that forms of fortune water pipe, the fortune pipe outer wall forms exhalant canal with fortune water jacket inwall; Cooling water gets into the fortune water pipe from water inlet, and recirculation gets in the fortune water jacket, flows along exhalant canal then, discharges from delivery port again, has formed a cooling water circulation.Cooling water has passed through the inside of main shaft and the inside of abrasive roller successively, reaches the effect that the outside material of main shaft, abrasive roller and abrasive roller is cooled off.The cooling effect of main shaft is strengthened, prolonged its useful life; Prevent the high temperature deformation of abrasive roller, improved the product quality of material.
So, the utlity model has following beneficial effect:
1, cooling water gets into the inside fortune water pipe of main shaft from water inlet, discharges from the fortune water jacket exhalant canal of the outer wall of main shaft again at last, and main shaft has been carried out sufficient dual-cooled, has strengthened cooling effect, prolongs its useful life;
2, cooling water has carried out the circulation cooling to it after getting into abrasive roller from the center to the inwall, has prevented the high temperature deformation of abrasive roller, improves its grinding effect;
3, the abrasive roller inwall is provided with spiral tank, has slowed down the flowing velocity of water, strengthens its cooling effect to abrasive roller, and then reaches the cooling to material, has kept the characteristic of material, makes its quality unified reliable.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the utility model cross-sectional view;
The 1-bearing block, 2-grinds cylinder body, the 3-water inlet, the 4-delivery port, the 5-main shaft, 6-transports water pipe, and 7-transports water jacket, 8-abrasive roller.
The specific embodiment
The interior cooling device of sand mill as shown in Figure 1 comprises bearing block 1, main shaft 5 and installs in the abrasive roller 8 of main shaft 5 ends, and abrasive roller 8 is positioned at and grinds cylinder body 2 inner chambers.Said main shaft 5 is provided with the fortune water pipe 6 that is communicated with the inner chamber of abrasive roller 8, and said fortune water pipe 6 outer walls and main shaft 5, abrasive roller 8 inwalls form fortune water jacket 7.Said bearing block 1 is provided with water inlet 3 and delivery port 4, and said water inlet 3 is communicated with fortune water pipe 6, and delivery port 4 is communicated with cooling water circulation canal in the formation with fortune water jacket 7, and abrasive roller 8 inwalls are provided with spiral tank.
Water inlet and fortune cross current in the utility model, delivery port is communicated with the fortune water jacket, and promptly at the inner intake tunnel that forms of fortune water pipe, the fortune pipe outer wall forms exhalant canal with fortune water jacket inwall, forms the circulation canal of a cooling water.During work, cooling water gets into the fortune water pipe from water inlet, and recirculation gets in the fortune water jacket, flows along exhalant canal then, discharges from delivery port again, has formed a cooling water circulation.Cooling water has passed through the inside of main shaft and the inside of abrasive roller successively, reaches the effect that the outside material of main shaft, abrasive roller and abrasive roller is cooled off.Cooling water gets into the fortune water pipe from water inlet, discharge from the outer fortune water jacket exhalant canal of main shaft again at last, to the carrying out of main shaft sufficient cooling, strengthened cooling effect, prolong its useful life; Cooling water has carried out the circulation cooling to it after getting into abrasive roller from the center to the inwall, prevented the high temperature deformation of abrasive roller, improves its grinding effect; Be provided with spiral tank in the fortune water jacket, slowed down the flowing velocity of water, strengthen its cooling effect, and then reach cooling, kept the characteristic of material, make its quality unified reliable material to the abrasive roller outer wall.
Above embodiment is not limited only to the protection domain of the utility model, and all are based on the basic thought of the utility model and the protection domain that all belongs to the utility model of making amendment or changing.
