Description

TECHNICAL FIELD

[0001] The utility model relates to a residue water separation treatment structure technical field, specifically is a kind of biodiesel pretreatment residue water automatic discharge device. BACKGROUND

[0002] The current traditional grease tank drainage residue method mainly uses manual drainage residue, i.e. the tank bottom is equipped with a ball valve and a sight glass, the bottom ball valve is opened manually at regular intervals, the water residue condition is observed through the sight glass, when the sight glass is observed to discharge grease, the valve is closed to stop drainage residue. This manual operation method has uncertainty, as the work is busy, sometimes forget to open the valve, resulting in water residue entering the backend system, or inaccurate valve closing time resulting in waste caused by more grease being discharged with water residue.

[0003] To eliminate the uncertainty of manual operation, the present application realizes automatic drainage residue function by physical mechanical method, which can save labor and effectively eliminate the influence of water residue entering the backend system on normal production caused by forgetting to discharge, or waste caused by more grease being discharged due to inaccurate valve closing time.

[0004] Therefore, we propose a biodiesel pretreatment residue water automatic discharge device. UTILITY MODEL CONTENTS

[0007] Further, hinge shaft one and hinge shaft two are self-rotated at both ends of the fixed plate, the hinge shaft one is fixedly connected with the middle part of the main connecting plate, and the hinge shaft two is fixedly connected with the middle part of the slave connecting plate.

[0008] Further, a sliding groove is formed in the slave connecting plate, a sliding plate is slidably matched in the sliding groove, hinge shaft three is self-rotated on the sliding plate, and the hinge shaft three is fixedly connected with one end of the main connecting plate.

[0012] Compared with the prior art, the present application has the following beneficial effects:

[0013] In the present application, the oil is stored in the tank body during the pretreatment of the biodiesel, and the stored oil contains a part of water slag. The existence of the water slag affects the oil quality, and the density of the water slag is heavier than that of the oil (the same volume of water slag is heavier than that of the oil), which is deposited at the bottom of the tank body. When the water slag accumulates to a certain extent, the water slag deposited at the bottom of the tank needs to be discharged in time to avoid affecting the subsequent treatment. By utilizing the different densities of the water slag and the oil, and adopting the mechanical principle of force arm lever, when the water slag accumulates to a certain extent, the liquid level changes, the reverse mechanical force arm is utilized to open the slag discharge pipe, and the water slag is automatically discharged from the tank. When the water slag is discharged to a low liquid level, the slag discharge pipe is closed.

[0014] The key point of the present application is to utilize the different densities of different liquids, so that the generated buoyancy is also different. By utilizing the stress change and the lever structure, a mechanically stable automatic operating mechanism is provided, the separation of the foreign matters is realized, the uncertainty of manual operation is reduced, the labor cost is saved, and the water slag is automatically discharged without the need of additional driving facilities.
