Abstract
The utility model provides a water-cooled riding wheel mechanism for a rotary kiln. The water-cooled riding wheel mechanism for the rotary kiln comprises riding wheels, a riding wheel shaft, bearings, bearing covers, bearing seats, bearing end covers, water intake pipes, water outlet pipes and a temperature measuring instrument. The water-cooled riding wheel mechanism for the rotary kiln is characterized in that the riding wheels are sleeved on the riding wheel shaft; two sides of the riding wheel shaft are provided with the bearings installed between the bearing seats and the bearing covers; small holes are formed in the bearing end covers; the temperature measuring instrument extends from the small holes so as to measure the temperature of the bearings in the bearing seats; the bearing seats are internally provided with water channel loops; inlets and outers of water channels are positioned in the circular arc back surfaces of the bearing seats, and are connected with the water intake pipes and the water outlet pipes through threads; cooling water flows into the water channels and the bearing seats through the water intake pipes for full heat exchange, and then flows out of the water outlet pipes. According to the utility model, the cooling water takes away the heat of the bearing seats, and takes away the high-temperature heat in the riding wheel mechanism continuously, so that the bearings are always at the low-temperature state and an effect of lowering the riding wheel bearing temperature is achieved. Therefore, the service lives of the riding wheel bearings are prolonged greatly, and the reliability of the riding wheel bearings is improved greatly.
Description
Technical field
The utility model relates to a kind of rotary furnace equipment, relates in particular to the water-cooled wheel holding mechanism of rotary furnace.
Background technique
In the industries such as chemical industry, metallurgy, building materials, rotary furnace is a kind of equipment that is widely used in dry materials and reaction.Carry out in rotary furnace when material generally needing heat-loading body to provide a large amount of heats to material in stove in the process of drying or reaction, therefore, usually be in the higher temperature state during rotary furnace work, sometimes the interior temperature of stove is even up to more than 600 degrees centigrade.
The rotary furnace support unit is generally wheel holding mechanism, and wheel holding mechanism is supporting the weight of whole rotary furnace and material, and makes cylindrical shell and rolling ring smooth rotation on support roller.Wheel holding mechanism mainly is comprised of support roller, supporting-roller shaft, bearing, bearing support etc.Due to support roller and cylindrical shell rolling ring close contact, thus stove in high temperature certainly will be delivered on the bearing of support roller and support roller, make bearing of conveyor idler be in for a long time under high temperature and work, had a strong impact on the working life of bearing of conveyor idler.
Summary of the invention
The purpose of this utility model is to provide a kind of water-cooled wheel holding mechanism for rotary furnace for the defective of existing rotary furnace wheel holding mechanism, and is with low cost, and bearing of conveyor idler remained under the low-heat temperature state move.
The technical solution of the utility model is: a kind of water-cooled wheel holding mechanism for rotary furnace, comprise support roller, supporting-roller shaft, bearing, bearing cap, bearing support, bearing (ball) cover, intake pipe, outlet pipe, thermometric instrument, it is characterized in that support roller is enclosed within on supporting-roller shaft, bearing is equipped with in the supporting-roller shaft both sides, and bearing is arranged between bearing support and bearing cap; Bearing (ball) cover has aperture, and thermometric instrument aperture thus stretches into the temperature of measuring bearing in bearing block; Described bearing support inside is with the water channel loop, and the import and export of water channel are positioned at the bearing support circular back, is threaded connection with intake pipe and outlet pipe, and cooling water carries out sufficient heat exchange through intake pipe inflow water channel and bearing support, and then flows out through outlet pipe.
Effect of the present utility model is that thermometric instrument is transferred to temperature controller with the temperature that measures, flow regulator is regulated the cooling water flow of inlet water at any time according to bearing temperature, utilize cooling water to take away the heat of bearing support, constantly the high temperature torrid zone in wheel holding mechanism is walked, make bearing be in all the time low-temperature condition, thereby play the effect that reduces the bearing of conveyor idler temperature, greatly improved the life and reliability of bearing of conveyor idler.

Fig. 3 is the plan view of Fig. 2.
Embodiment
As shown in Figure 1, a kind of water-cooled wheel holding mechanism for rotary furnace described in the utility model mainly is made of support roller 6, supporting-roller shaft 7, bearing 8, bearing support 9, bearing cap 5, intake pipe 4, outlet pipe 3, thermometric instrument 1, bearing (ball) cover 2 etc.Support roller 6 is enclosed within on supporting-roller shaft 7, and two bearings 8 are equipped with in supporting-roller shaft 7 both sides, and bearing 8 is arranged between bearing support 9 and bearing cap 5.Bearing (ball) cover 2 has aperture, and thermometric instrument 1 aperture thus stretches into the temperature of measuring bearing support 9 inner bearings 8.
As shown in Figure 2 and Figure 3, bearing support 9 adopts the thickening design, in casting forward position outer arc shape embedding water pipe circuit, then global formation, thus at the inner water channel that forms of bearing support 9, the import and export of water channel are positioned at bearing support 7 circular backs, and the import and export car of water channel has screw thread, are connected with outlet pipe with intake pipe 4 through screw thread to be connected.Cooling water carries out sufficient heat exchange through intake pipe 4 inflow water channels and bearing support 9, and then flows out through outlet pipe 3.
