Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail.

See Figure 1. A metering and conveying device for yellow palm esterification liquid, comprising a yellow palm esterification liquid storage tank 1, a feeding pump 4, a high-level metering tank 5, a weighing module 6, a PLC programmable controller 10, a first discharge pipeline 3, The second discharge pipeline 7 , the signal line 9 , the check valve 2 and the solenoid valve 8 . The yellow-palm esterified liquid storage tank 1 is a columnar structure with a first feed port 1.1 on the top and a first discharge port 1.2 on the bottom. The top metering tank 5 is provided with a second feed port 5.1, and the bottom is provided with a second discharge port 5.2. In order to ensure the service life of the high-level metering tank 5, its manufacturing material is preferably stainless steel. One end of the first discharge pipeline 3 is connected to the first discharge port 1.2, the other end is connected to the second feed port 5.1, and a check valve 2 and a feeding pump 4 are sequentially installed on the pipeline. One end of the second discharge pipeline 7 is connected to the second discharge port 5.2, and a solenoid valve 8 is installed on the pipeline. The weighing module 6 is installed at the bottom of the high metering tank 5 . Considering that the high-level metering tank 5 is mainly subjected to vertical force, the weighing module 6 adopts a static load weighing module. The static load weighing module mainly includes sensors, top plates, bottom plates and connectors. The PLC programmable controller 10 is respectively connected with the weighing module 6 and the solenoid valve 8 through the signal line 9 .

The basic working principle of the utility model is as follows:

The yellow palm esterification liquid enters the yellow palm esterification liquid storage tank 1 from the first feed port 1.1 for temporary storage. When starting to operate, open the check valve 2, the yellow palm esterification liquid enters the first discharge pipeline 3 from the first discharge port 1.2, and is sent into the high-level metering tank 5 through the feeding pump 4; it is accurately weighed by the weighing module 6 After the amount is measured, the weight information is transmitted to the PLC programmable controller 10 by the signal line 9; the amount added per minute is calculated according to the process, and the feeding speed is set by the PLC programmable controller 10, and the instruction is transmitted to the solenoid valve 8 by the signal line 9 ; The solenoid valve 8 adjusts the flow rate according to the instruction.
