Problems solved by technology

[0002] Waste liquid treatment in nuclear power plants needs to be loaded with a large number of concrete containers, otherwise it will lead to nuclear leakage, resulting in immeasurable losses and pollution. The existing cement transportation is carried out by screw conveyors, which may easily lead to blockage during the transportation process. And dry, and can only be transported in one direction, the degree of automation is low, the feed metering cannot be automatically controlled, and it needs to be improved

Embodiment 1

[0009] Embodiment 1: A nuclear power plant cement delivery system, including a cement silo 1, a bag filter 2 arranged on the top of the cement silo 1 and connected to it, and the discharge port at the bottom of the cement silo 1 is connected through a discharge pipe 3 The feeding port of the screw conveyor 4, the screw conveyor 4 is provided with two discharge ports 4.2 respectively located on both sides of the feeding port of the screw conveyor 4, and the side wall near the bottom of the cement silo 1 is provided with a bin wall vibrator 5. A level meter 6 is arranged in the cement silo 1, and a No. 1 solenoid valve 7 is arranged at the feed inlet 1.1 at the top of the cement silo 1 . The discharge pipeline 3 is provided with a No. 2 solenoid valve 8, and the No. 2 solenoid valve 8 is provided with a pressure gauge 9. The cement silo 1 is provided with a PLC controller 10, and the PLC controller 10 is signal-connected to the level meter 6, the pressure meter 9, and No. 1 and...

Embodiment 2

[0010] Embodiment 2: Referring to Embodiment 1, the cement silo 1 is provided with a stirring shaft 11 , the top end of the stirring shaft 11 is connected to a motor 12 , and the bottom end of the stirring shaft 11 is provided with a helical elastic coil 13 .

[0011] Workflow: The cement conveying system conveys dry cement to the grouting receiving silo or the curing receiving silo. When the level meter reaches a high setting value, close the inlet valve, and when it reaches a low setting value, close the outlet valve; when the pressure meter reaches high pressure, close the inlet valve, and when the pressure is low, close the outlet valve. When the conveying pipe is blocked, the bin wall vibrator is turned on to loosen the densely packed cement and prevent the cement from agglomerating. The screw conveyor can rotate forward and reverse to transport cement to the two silos respectively.

Abstract

The invention provides a cement conveying system for a nuclear power plant. The cement conveying system comprises a cement stock bin and a bag-type dust collector arranged at the top end of the cementstock bin and communicating with the cement stock bin. A discharging opening in the bottom end of the cement stock bin is connected with a feeding opening of a spiral conveyer through a discharging pipe, the spiral conveyer is provided with two discharging openings which are formed in the two sides of the feeding opening of the spiral conveyer correspondingly. The side wall, close to the bottom end, of the cement stock bin is provided with a bin wall vibrator. A plurality of detection devices are arranged, switch-on and switch-off of a valve are controlled automatically through a controller,and the automated degree is greatly increased; and the bin wall vibrator is arranged, drying and hardening and blocking are effectively prevented, and conveying efficiency is improved.

Description

technical field [0001] The invention relates to a conveying device for pouring cement in a nuclear power plant. Background technique [0002] Waste liquid treatment in nuclear power plants needs to be loaded with a large number of concrete containers, otherwise it will lead to nuclear leakage, resulting in immeasurable losses and pollution. The existing cement transportation is carried out by screw conveyors, which may easily lead to blockage during the transportation process. And dry, and can only be transported in one direction, the degree of automation is low, and the feed metering cannot be automatically controlled, so it needs to be improved. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a nuclear power plant cement conveying system with a high degree of automation, which can effectively prevent dry cement from clogging and greatly improve conveying efficiency. [0004] In order to achieve the purpose of the pr...
