Problems solved by technology
This device effectively improves the quantitative accuracy, but the device has a complicated structure and high cost, and at the same time, it fails to solve the problem of air being sucked into the vacuum system when the clay stock is insufficient.
[0005] The common feature of the closed screw feeding device and the small scale feeding device is that the material is used as the sealing medium between the atmosphere and the vacuum equipment, and the sealing problem of the equipment cannot be solved from the root cause

Embodiment Construction
[0023] Such as figure 1 As shown, the vegetable oil refining white clay quantitative addition device of the present invention includes a normal pressure storage hopper 1, a feed valve YV1 is installed at the bottom of the normal pressure storage hopper, a quantitative cylinder 2 is installed below the feed valve, and a quantitative cylinder 2 is installed below the quantitative cylinder. Discharge valve YV2, the outlet of discharge valve YV2 is connected with vegetable grease vacuum container 3.
[0024] In the vegetable oil vacuum container 3 every fixed cycle, a certain amount of clay needs to be added, and the clay is stored in the normal pressure storage hopper 1. Under normal conditions, both the feed valve YV1 and the discharge valve YV2 are closed, and the vegetable oil The airtightness of the vacuum container 3 is very reliable. When clay needs to be added, firstly open the feed valve YV1 to let the clay enter the quantitative cylinder 2, then close the feed valve YV1...

The invention relates to a quantitative addition device and method for vegetable oil refining white clay. A feed valve is installed at the bottom of an atmospheric storage hopper, a quantitative cylinder is installed below the feed valve, and a discharge valve is installed below the quantitative cylinder. The outlet of the valve is connected with the vegetable oil vacuum container. Both the feed valve and the discharge valve are electrically controlled airtight valves and are controlled by the control circuit, and a material level sensor is installed on the side wall of the atmospheric storage hopper. When there is enough material in the atmospheric storage hopper and it needs to be added, the feed valve will be opened automatically to store the material in the quantitative cylinder and realize accurate metering, then the feed valve will be closed, and the discharge valve will be opened to feed the vegetable oil into the vacuum container. Feeding, the feeding time is automatically controlled and very short, the discharge valve is automatically closed after the feeding is completed, and the above process is automatically started in the next cycle to realize fully automatic operation, and each feeding is very accurate and can ensure sealing.
Description
technical field [0001] The invention relates to a device for quantitatively adding white clay for vegetable oil refining, and also relates to a method for quantitatively adding white clay for vegetable oil refining, which belongs to the technical field of vegetable oil refining process control. Background technique [0002] During the refining process of vegetable oil, it is necessary to add white clay from the atmospheric pressure storage equipment to the vegetable oil in the vacuum environment according to a certain proportion. In the process of adding, it is easy to add inaccurately and easily destroy the vacuum environment in the equipment. [0003] The existing adding technology mainly adopts closed screw feeding device and small scale quantitative feeding device. The closed screw feed is added through the frequency converter to control the screw rotation speed. The added amount is theoretical data, and the quantitative accuracy is unstable and uncontrollable. Entering...
