Abstract

The utility model relates to a water-cooling roller device for flour mills. The utility model is formed by that the pig iron part of the existing solid core roll can be removed, and both ends of an alloy roller are respectively and additionally provided with an end cover, a hollow roll shaft and a shaft end water and gas sealing device. The outer ends of two end covers and the alloy roller present sealing state, a mechanism roll drum is provided with water outlet holes, an annular water chamber and semicircular guiding hole. The hollow roll shaft is provided with radial perforations. Cooling water flows into the inner chamber of a roll drum by the shaft end water and gas sealing device, the hollow roll shaft, the radial perforations on the hollow roll shaft, the water outlet holes, the annular water chamber and the semicircular guiding hole, and then, the cooling water exhausts out form the other end. The utility model has the advantages of good cooling effect, light weight, high flour quality, low temperature rise of a bearing shell, etc.

Description

Flour mill water cooling Burnisher apparatus

The utility model belongs to the water cooling Burnisher apparatus of using on the flour mill.

In the prior art, the grinding roller of using on the flour mill is solid grinding roller.The most outstanding shortcoming of this grinding roller is: (1) heat radiation is slow, and the roll temperature height influences the quality of flour, and promptly the lighter's poor toughness, fragrance are light; Weight person causes flour rotten, can not eat; (2) heaviness; (3) bearing shell temperature rise, easy to wear.To the problems referred to above, many manufacturers and expert, scholar competitively study, inquire into, but do not obtain breakthrough solution.

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of flour mill water cooling Burnisher apparatus is provided.It can not only reduce the temperature of grinding roller and bearing shell, improves flour quality, and weight only be the 50-60% of solid grinding roller, and the while has also prolonged the life-span of bearing shell significantly.

The utility model has been taked following several measures:

The first, remove the pig iron part that has solid grinding roller now, keep its alloy-layer---alloy roller, its wall thickness are 20-30mm.Two ends at the alloy roller have an end cap respectively.Alloy roller and two end cap are to adopt centrifugally cast method to fasten as one, and constitute the roller drum.The roller drum is hollow.

The second, two roll shaft has a centre bore respectively.Two roll shafts are in the center port of an end in the roller drum with silently blocking.Middle part in two roll shafts and two end cap junction has 4 perforation respectively along its radial direction.

Three, two end cap is an iron casting, it with two roll shafts between become the tight fit state.Its radial direction of end cap upper edge has 4 apopores, and outside herein and inwall have each one of large and small annular water chamber respectively.These apopores and annular water chamber all communicate with 4 perforation of two roll shafts.Two end cap is in the periphery of roller drum inner chamber one end, has half garden shape pod apertures, and the periphery of its outer end has the sealing seam, in case leak.The periphery of two end cap is all imbedded alloy roller inwall 4-6 millimeter.

The 4th, have an axle head water, gas sealing mechanism respectively in two roll shaft outer ends and inlet pipe, drain pipe junction.The horizontal plane of circulating water pool is a little more than the axial location of water cooling grinding roller.Simultaneously, water circulating pump is placed the water side of flour mill water cooling grinding roller.Cooling water from circulating water pool enters roller drum inner chamber through axle head water, gas sealing mechanism and hollow roll shaft, enter the water inlet of water circulating pump then from the other end, by water circulating pump it is squeezed into circulating water pool at last, thereby reach the purpose that reduces grinding roller and bearing bush temperature.

Owing to take above-mentioned measure, so, to compare with existing solid grinding roller, this device has advantages such as grinding roller and bearing shell rapid heat dissipation, temperature are low, in light weight.Promptly fundamentally solved because of high this hard nut to crack that influences flour quality of roll temperature.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the vertical section structure schematic diagram of flour mill water cooling Burnisher apparatus first embodiment.

Fig. 2 is the front view that the end cap of Fig. 1 is positioned at roller drum inner chamber one end.

Fig. 3 is the vertical section structure schematic diagram of water cooling Burnisher apparatus second embodiment.

Hollow roll shaft 3. roll shaft centre bores 4. end caps of 1. axle head water among the figure, gas sealing mechanism 2. 5. 6. end cap apopores, 7. little annular water chamber 8. of big annular water chamber are 9. rollers drum inner chamber, 10. alloy rollers, 11. pod apertures, 12. end cap seal seams, 13. roll shaft radial perforations, 14. bearing shells silently.

In the embodiment shown in fig. 1, end cap (4) is an iron casting, and it and alloy roller (10) are to adopt centrifugally cast method to fasten as one, and constitute the roller drum.The roller drum is hollow.The periphery of end cap (4) outer end has sealing seam (12), and the periphery of inner end has half garden shape pod apertures (11), shows as Fig. 2, and its periphery is a zigzag.Have big annular water chamber (5) between end cap (4) and the alloy roller (10), and have little annular water chamber (7) between the roll shaft (2).Between big annular water chamber (5) and little annular water chamber (7), have 4 end cap apopores (6).The periphery at end cap (4) two ends is all imbedded alloy roller (10) inwall 4-6 millimeter.The aperture that roll shaft centre bore (3) is positioned at roller drum inner chamber (10) blocks with silently (8).Junction at roll shaft (2) and end cap (4) has 4 perforation (13), and this hole communicates with roll shaft centre bore (3), little annular water chamber (7), end cap apopore (6), big annular water chamber (5), pod apertures (11), roller drum inner chamber (9).(14) be bearing shell.

The structure at these device two ends is identical.

Cooling water enters roller drum inner chamber (9) through axle head water, gas sealing mechanism (1), roll shaft centre bore (3), the radial perforation (13) of hollow roll shaft (2), little annular water chamber (7), end cap apopore (6), big annular water chamber (5), half garden shape pod apertures (11).Discharge from the grinding roller other end then, and it is squeezed into circulating water pool by water circulating pump.

In another embodiment shown in Figure 3, the two ends of alloy roller (10) have an end cap (4) respectively.Hollow roll shaft (2) is an axis, and two ends have a roll shaft centre bore (3) respectively, and this two hole is not connected along axis direction.End cap (4) is an iron casting, and periphery has sealing seam (12), and end cap (4) and alloy roller (10) are to adopt centrifugally cast method to fasten as one, and constitute the roller drum.The periphery of end cap (4) is imbedded alloy roller (10) inwall 4-6 millimeter.Hollow roll shaft (2) belongs to tight fit with end cap (4).Cooling water flows into roller drum inner chamber (9) through the radial perforation (13) of axle head water, gas sealing mechanism (1), roll shaft centre bore (3), hollow roll shaft (2), discharges from the other end then, and through water circulating pump it is squeezed into circulating water pool.

The structure at these device two ends is identical.

Can see that from above-mentioned two embodiment cooling water has also cooled off bearing shell (14) in cooling roller (10), roll shaft (2).
