Embodiment 1

[0013] Embodiment 1. In the present invention, a valve seat sealing end cover 3, a rotating shaft 2, a bearing seat bracket and a bearing seat are respectively arranged at one or both ends of the rotary valve base 5, and the bearing seat bracket 4 is fixedly connected with the valve seat sealing end cover 3. The rotating shaft 2 is connected with the rotating valve shaft in the rotary valve base 5, and the rotating shaft 2 is set in the bearing 16 of the bearing seat 1. It maintains a certain distance between the bearing and the rotary valve base 5 by setting the bearing seat bracket 4, thereby effectively protecting Good bearings improve the service life of the bearings; and set the valve seat sealing end cover 3 at the end of the rotary valve base 5 to facilitate installation and maintenance; Plate 6, motor 7 and reducer 8 are installed on the outside of isolation plate 6, so that motor 7, reducer 8 and rotary valve base 5 also keep a certain distance, which reduces heat cond...

Embodiment 2

[0014] Embodiment 2, the present invention also can be equipped with chain shield 11 outside speed reducer sprocket 10, transmission sprocket 14 and chain 12, mainly plays a protective role. refer to Figure 1 to Figure 3 , all the other are with embodiment 1.

Embodiment 3

[0015] Embodiment 3, the present invention can also provide a mounting support 13 between the outer side of the isolation plate 6 and the motor 7 or the reducer 8, which is not only convenient for installation, but also increases the isolation distance, thereby improving the high temperature resistance. refer to Figures 1 to 3 , and the rest are the same as the above-mentioned embodiment.

Abstract

The invention relates to a high-temperature rotary valve which mainly solves the technical problem that the traditional rotary valve can not be used for conveying high-temperature powders and the like. The technical scheme of the invention has the main points that one end or both ends of a rotary valve base is / are respectively provided with a valve seat seal end cover, a rotary shaft, a bearing seat support and a bearing seat; the seal end cover is matched with the end of the rotary valve base; the rotary shaft and a rotary valve shaft in the rotary valve base are matched and connected; the rotary shaft is sleeved in the bearing of the bearing seat; the bearing seat support and the seal end cover are fixedly connected; isolating boards are matched and fixedly arranged at one side of the rotary valve base at intervals; the rotary shaft of one end of the rotary valve base passes through the bearing seat and is sleeved with a driving chain wheel at the outer end; the outer sides of the isolating boards are provided with motors and reduction gears; the rotary shafts of the reduction gears pass through reduction gear end covers, and the outer ends of the reduction gear end covers are provided with reduction gear chain wheels; and chains are matched and arranged between the reduction gear chain wheels and the driving chain wheel. In the invention, the bearing and the rotary valve base keep a certain distance through installing the bearing seat support, and thereby, the bearing is effectively protected, and the service life of the bearing is prolonged; the motor and the reduction gears keep a certain distance with the rotary valve base through installing the isolating boards, and the heat conduction is reduced. The invention is mainly used for occasions of conveying the high-temperature powders and the like.

Description

technical field [0001] The invention relates to a rotary valve for conveying powder, in particular to a rotary valve for conveying high-temperature powder. Background technique [0002] At present, rotary valves are mostly used in the process of loading and unloading or conveying powder, while the rotating shaft of ordinary rotary valves directly passes through the bearing and connects with the motor or through a reducer. Because the temperature in the rotary valve is easily transmitted to the bearing, motor or reducer through the rotating shaft of the rotary valve, it will cause serious damage to the bearing, motor or reducer. Therefore, ordinary rotary valves cannot be used to transport high-temperature powder. Contents of the invention [0003] The object of the present invention is to provide a high-temperature rotary valve that can be used for conveying high-temperature powder. [0004] The technical solution adopted by the present invention to solve its technical pr...
