Description
Technical Field
The utility model discloses an adopt city reclaimed water as the thermal power factory at water main source, city reclaimed water adopts lime softening treatment system as the supplementary pretreatment of water technology of power plant, belongs to city reclaimed water lime softening treatment field, especially relates to a modified power plant lime silo unloading system.
Background
In the existing urban recycled water lime softening treatment system of a power plant, for the cone hopper part of a lime silo, due to the extrusion of the whole silo material and the fact that the section of a discharging opening is smaller and smaller, after the lime material in the lime silo is affected with damp, the agglomeration of lime powder is very strong, although the size of a single particle is not large, the particles are bonded with each other under the condition that moisture exists, and the formed physical size is very large. In addition, near the discharge port, the lime material flows in a confluence state, all the lime material moves towards the center in a staggered manner, particles are close to each other and extruded to form a cluster, and the physical size of the particles is also large. When the ratio of the particle size at this location to the size of the discharge orifice reaches a plugging threshold, a plug will form.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the above-mentioned prior art, the utility model aims at providing a modified power plant lime silo unloading system.
The purpose of the utility model is realized with the following mode:
the improved blanking system of the lime silo of the power plant comprises the silo, a cone hopper, a vibrator and a mechanical stirring device, wherein the silo is connected with the cone hopper through a first flexible part, the vibrator is arranged on the outer wall of one side of the cone hopper, the mechanical stirring device is arranged on the other side of the cone hopper, and a stirring paddle of the mechanical stirring device extends into the cone hopper.
The awl is fought the outside and is set up the female pipe of annular compressed air, and the female pipe air inlet of compressed air sets up the butterfly valve, sets up two at least compressed air branch pipes on the female pipe of compression, and in the compressed air branch pipe evenly distributed just stretched into the awl and fight, the export is fought towards the awl to the gas outlet.
Still include the host computer, the butterfly valve is pneumatic butterfly valve, the host computer is connected with vibrator, mechanical agitating unit, start-up butterfly valve.
The cone hopper feed opening is connected with a feed pipe through a second flexible piece, and the feed pipe is provided with a gate valve.
The first flexible member and the second flexible member are rubber joints.
Compared with the prior art, the utility model discloses can sweep the device through at lime silo awl fill lower part installation vibrator, mechanical stirring device and strength, solve the problem that lime silo lower part material easily blockked up, make the fail safe nature and the material conveying efficiency of system obviously improve to operation, maintenance volume and operation, maintenance cost have been reduced.

Detailed Description
As shown in fig. 1, an improved discharging system for a lime silo in a power plant comprises a silo 1, a cone hopper 2, a vibrator 4 and a mechanical stirring device 5, wherein the silo 1 and the cone hopper 2 are connected through a first flexible part 3, the vibrator 4 is arranged on the outer wall of one side of the cone hopper 2, the mechanical stirring device 5 is arranged on the other side of the cone hopper, and a stirring paddle of the mechanical stirring device 5 extends into the cone hopper.
The awl is fought 2 outsides and is set up female pipe 7 of annular compressed air, and the female 7 air inlets of pipe of compressed air set up butterfly valve 6, and 7 sets up two at least compressed air branch pipes 8 on the female pipe of compressed air, and 8 evenly distributed of compressed air branch pipe just stretch into the awl and fight 2 in, the export is fought towards the awl to the gas outlet.
Still include the host computer, butterfly valve 6 is pneumatic butterfly valve, the host computer is connected with vibrator 4, mechanical agitating unit 5, pneumatic butterfly valve.
The discharge opening of the cone hopper 2 is connected with a discharge pipe 10 through a second flexible piece 9, and a gate valve 11 is arranged on the discharge pipe 10.
The first flexure 3 and the second flexure 9 are rubber joints.
The silo 1 and the cone hopper 2 are connected through the first flexible part 3, the flexible connection belongs to flexible connection and can play a role in buffering, and when the vibrator 4 and the mechanical stirring device 5 work, the flexible connection can reduce the influence of vibration on the upper part of the silo; similarly, a second flexible part 9 is arranged between the feed opening of the conical hopper 2 and the feed pipe 10, so that the influence on the connection part between the feed pipe 10 and the lower part of the feed pipe 10 is reduced when the vibrator 4 and the mechanical stirring device 5 work. The blanking pipe 10 is provided with a gate valve 11 to prevent lime in the silo 1 from falling down during maintenance.
In the specific working process: the system runs for 3-5 periods, each period is 6-8 hours, the upper computer sends an instruction to start the vibrator 4, the cone hopper 2 is vibrated left and right for 30 seconds to 1 minute, then the mechanical stirring device 5 is started to drive the stirring paddle in the silo to rotate for 1 minute, finally, the pneumatic butterfly valve is opened, and compressed air is introduced into the cone hopper 2 to perform pneumatic purging for 30 seconds. The time can be adjusted according to specific conditions. Each process can also be operated in a point mode, and when the lime system is blocked, vibration, stirring or pneumatic purging can be realized in the control room through a single point operation program.
Others refer to the prior art.
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
