Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the present invention and the present invention is not limited to the following examples.

[0025] see Figure 1-Figure 6 , a water treatment membrane element protective liquid replacement device, including feeding and discharging trolley 1, material frame 2, front lifting trolley 4, rear lifting trolley 5, liquid storage tank 6, circulation system 7, replacement chamber 8 and fan 9.

[0026] The replacement chamber 8 is used for isolation to prevent the protection liquid from spreading into the workshop.

[0027] The feeding and discharging trolley 1 is mobile installed on the ground, and is used for feeding the material frame 2 and the water treatment membrane element 3 into and out of the replacement chamber 8 .

[0028] The material frame 2 is used to load water treatment membrane elements 3, and can ...

Abstract

The invention provides a replacement device of protective liquid of a water-treating membrane element and a replacement method thereof. The replacement device is reasonable in structural design, low in labor intensity, full in filling and thorough in drainage. The replacement device is characterized in that a material frame is installed on a feeding and discharging cart, the feeding and discharging cart is flatly moved into a replacement room from the outer side of the replacement room, and a front lifting mechanism and a rear lifting mechanism lift the material frame to a certain height aftergrabbing the material frame; the material frame is flatly moved to above a liquid storage groove by a front moving mechanism and a rear moving mechanism; the material frame is sunk into the liquid storage groove by the front lifting mechanism and the rear lifting mechanism to fill the protective liquid into the water-treating membrane element; the material frame is separated from the liquid storage groove and forms a certain angle with the ground by the front lifting mechanism and the rear lifting mechanism; the material frame is lifted to above the liquid storage groove by the front liftingmechanism and the rear lifting mechanism; the material frame is flatly moved to above the feeding and discharging cart by the front moving mechanism and the rear moving mechanism; the material frame is placed on the feeding and discharging cart by the front lifting mechanism and the rear lifting mechanism; after the material frame is loosened by the front lifting mechanism and the rear lifting mechanism, and the feeding and discharging cart conveys the material frame out of the replacement room so as to finish a protective-liquid filling process.

Description

technical field [0001] The invention relates to a water treatment membrane element protective liquid replacement device and a replacement method thereof. Background technique [0002] Water treatment membrane elements such as ultrafiltration membrane elements, nanofiltration membrane elements, and reverse osmosis membrane elements need to be filled with protection liquid into the inside of the membrane elements before they are rolled in the factory and finally shipped. The surface of the membrane is dry and cracked, and the accumulation of test water will cause the growth of microorganisms and bacteria inside the membrane element. At present, manual operation is generally used to pour protective solutions such as glycerin or sodium bisulfite into the membrane elements, which has the disadvantages of high labor intensity, insufficient filling, and incomplete draining. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned...
