Description

Inner Case and Rotary Blade Replacement Rotary Valve {INSIDE CASE AND REVOLVING BLADE CHANGABLE ROTARY VALVE}

The present invention relates to an improvement of a rotary valve which is widely used as a means for continuously discharging and supplying various kinds of powders. In particular, a space caused by wear or corrosion occurs between a rotary blade and a case inner surface during use of a rotary valve. When the adhesion of the powder occurs due to moisture, and the operation of the rotary valve is not smooth, it is possible to quickly replace and repair the rotary valve, which is heavy, without being separated from the facility.

In general, rotary valves are widely used for discharging, quantitatively supplying, and transporting various kinds of powders.At the same time, airtightness must be maintained between the rotary blades fitted in the rotary valves and the inner wall of the case. It becomes possible.

However, due to the long-term use of the rotary valve, wear between the rotating blades and the inner case of the body occurs due to friction, which causes a problem that the discharge and supply of powder cannot be made smoothly.

In addition, when the field in which the rotary valve is installed and used is applied to the incineration ash discharge generated at the bottom of the incinerator, or when moisture is applied to the discharge or supply of slaked lime or cement, the rotary blade and the main body fitted in the rotary valve are inserted. Corrosion occurs between the inner surface of the case or the powder is adhered by moisture, as well as noise and vibration is generated, and in severe cases, the drive motor is damaged by the stop of the rotating blade.

In this case, the rotary valve should be repaired immediately to prevent any disruption in production.

In other words, the conventional method of repairing a rotary valve requires a complete separation of the rotary valve from the facility and then disassembles it to process the inner surface of the main body case into a lathe, and the rotating braid must be remanufactured as the inner diameter increases due to lathe machining. In this case, if there is no rotary valve in the process that does not work, a spare spare rotary valve is prepared and replaced immediately so that production does not occur.

Even if a spare rotary valve is prepared and replaced immediately in case of failure, as described above, if the storage state of the rotary valve that has been left unused for a long time is not intact, there is a problem such as premature failure. Rather, it was a waste of unnecessary expense in purchasing expensive rotary valves.

In addition to these problems, it is not only difficult to separate heavy rotary valves from the facility after repair or replacement, but also to reassemble heavy rotary valves. There was a problem such as unavoidable production disruption.

In order to correct these problems, the present invention provides a space between the rotating blade and the case during use of the rotary valve due to abrasion, or does not operate smoothly due to corrosion and adhesion of the powder. In case of replacement, the heavy chain rotary valve can be quickly and easily replaced and repaired without being separated from the facility.

As a means for solving the above problems, the present invention is to disassemble and assemble the inner case coupled to the rotating braid on the inner surface of the outer case constituting the rotary valve, and assembled by the outer cover on both sides of the outer case in the above state. If the rotating blade or inner case needs to be repaired or replaced during use, only the outer cover should be removed while the rotary valve is connected to the facility, and then the inner case inserted in the outer case is pulled out to separate it. The new inner case was assembled and used.

The present invention is to disassemble and assemble the inner case of the rotary braid inserted into the inner case of the outer case constituting the rotary valve, the space is generated between the rotating broth and the inner case during use, or smooth operation is made by the adhesion of corrosion and powder If it is not possible to replace the heavy chain rotary valve from the facility, remove the outer cover from the outer case in the combined installation state, separate the inner case with the rotating braid, and assemble a new inner case. It can be effected such that they can be made quickly and easily repair replacements.
