Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1, the present invention provides an automatic liquid additive charging device, comprising: storage vat 1, the main pipe 2 of carrying that is connected with storage vat 1. The periphery of the storage vat 1 is provided with at least one heating and heat-preserving device (not shown), and the heating and heat-preserving device is preferably a hot water tank or a heat-preserving jacket additionally arranged on the outer wall of the storage vat 1, and is used for preserving heat of the liquid additive in the storage vat 1 and reducing the influence of temperature reduction on the liquidity of the liquid additive. The main conveying pipe 2 is provided with a main flow calibration device 21, a conveying pump 22 and a plurality of branch feeding mechanisms along the conveying direction. The delivery pump 22 is a metering pump that maintains a constant flow rate independent of the discharge pressure, and performs the functions of delivery, metering, and flow regulation simultaneously. Because the reciprocating motion of the metering pump plunger can cause the metering pump to generate certain pulse, the working performance efficiency of the metering pump is reduced, and therefore, the inlet end and the outlet end of the metering pump are respectively provided with the pulse damper 22, the impact of pressure fluctuation is reduced, the pipeline elbow is protected, and a good working environment is created for the metering pump. Branch's reinforced mechanism includes: the device comprises a conveying branch pipe 31, a discharge pipe 36 and a split flow calibration device 35, wherein one end of the conveying branch pipe 31 is communicated with a conveying main pipe 2, the other end of the conveying branch pipe 31 is communicated with the split flow calibration device 35, a feed valve 32 and a back pressure valve 34 are sequentially arranged on the conveying branch pipe 31 along the conveying direction, the feed valve 32 is preferably a flow control valve, the output flow can be controlled through the opening degree of the flow control valve, and then the final output quantity of each branch feeding mechanism is changed so as to meet the requirements of different proportions. The backpressure valve 34 is used for reducing the siphonage appearing at the outlet end of the delivery pump 23, reducing the fluctuation of the flow and the pressure, ensuring the normal output flow of the delivery pump 23, and simultaneously being matched with the pulse damper 22 for use, the pulse damper 22 can reduce the abrasion speed of the backpressure valve 34, and the service life of the backpressure valve is effectively prolonged. The communicating part of the conveying branch pipe 31 and the discharging pipe 36 is positioned between the back pressure valve 34 and the divided flow calibration device 35, the discharging pipe 36 is provided with a discharging valve 33, and the discharging pipe 36 is communicated with the batching tank 4.
Further, the main flow calibration device 21 and the branch flow calibration device 35 are both flow calibration columns. The main flow calibration device 21 is used for periodically performing measurement calibration on the delivery pump 22 to ensure the accuracy of the delivery amount of the delivery pump 22. The split calibration device 35 is used to periodically calibrate the flow rate of the delivery branch 31 to ensure that the amount of liquid additive entering the dosing tank 3 is accurate. The calibration process comprises the following steps: the discharge valve 33 is closed, the liquid additive will enter the divided flow calibration device 35, and the flow of the conveying branch pipe 31 can be calibrated by judging the amount of the liquid entering the divided flow calibration device 35 within a certain time.
Specifically, after the device is calibrated by the main flow calibration device 21 and the branch flow calibration device 35, the feed valve 32 and the discharge valve 33 are opened simultaneously, and the liquid additive is pumped into the proportioning tank 4 through the delivery pump 23 after the impact of pressure fluctuation is reduced by the pulse damper 22, so that the automatic adding process is completed.
