Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a wastewater treatment device for the production of etched foils. Background Art

[0002] During industrial production processes, a large amount of wastewater is usually generated. The wastewater contains many harmful or useful substances. Direct discharge without treatment will not only cause environmental pollution but also result in waste.

[0003] A cleaning liquid extraction device for treating etched foil process wastewater, a Chinese utility model patent with the application number 202022342660.1, adds chemical agents into a wastewater treatment tank to form fixed impurities from the chemical substances in the etched foil cleaning liquid. Then the solid substances are discharged into a sedimentation tank. After sedimentation in the sedimentation tank, the liquid on the upper layer is pumped into a heating tank by a water pump for heating and evaporation. The steam formed by evaporation is condensed and recovered by a cooler, realizing the recovery of chemical agents in the wastewater.

[0004] The inventor believes that when discharging the wastewater in the treatment tank into the sedimentation tank, the heavier fixed substances in the wastewater may precipitate faster. However, due to the impact force, some of the lighter impurities in the wastewater may take a longer time to precipitate. Therefore, a long waiting time is required. Although a filter pipe is provided on the second water inlet pipe, when pumping water directly without sufficient sedimentation time, it is inevitable to pump a lot of small impurities, causing the filter pipe to become blocked quickly.

[0005] Therefore, this application proposes a wastewater treatment device for the production of etched foils, aiming to minimize the waiting time for precipitation after the etched foil cleaning liquid is treated with chemical agents and improve the treatment efficiency. Summary of the Utility Model

[0006] In view of the above situation, to overcome the defects of the prior art, the utility model provides a wastewater treatment device for the production of etched foils to solve the above problems.

A drain pipe is fixedly provided at the lower end of the wastewater treatment tank. The drain pipe extends into the lower end inside the sedimentation tank, and an isolation net is sleeved outside the drain pipe. The isolation net can move up and down in the sedimentation tank and always remains above the lower end of the drain pipe. The isolation net is specifically arranged such that when the isolation net slides to the lowest position of the drain pipe, the liquid transfer mechanism can pump the wastewater in the sedimentation tank into the heating tank above the isolation net.

[0008] Preferably, the liquid transfer mechanism includes a water pump and a water suction pipe. The water pump is fixedly arranged on the surface of the base, and the water outlet of the water pump is connected to the inside of the heating tank. The water suction pipe is fixedly connected to the water inlet of the water pump, and the lower end of the water suction pipe vertically extends into the sedimentation tank. The height of the lower end of the water suction pipe is higher than that of the lower end of the drain pipe. A through hole for inserting the water suction pipe is provided through the isolation net.

[0009] Preferably, a plugging component for blocking the through hole is provided at the lower end of the sedimentation tank. The plugging component includes a plug rod. The lower end of the plug rod is fixed to the lower end of the sedimentation tank. When the isolation net slides to the lower end of the drain pipe, the water suction pipe is separated from the through hole, and the upper end of the plug rod is inserted into the through hole.

[0010] Preferably, a vertical slide rail is fixed to the inner wall of the sedimentation tank, and the isolation net is slidably connected to the vertical slide rail.

[0011] Preferably, a driving mechanism for driving the isolation net to move up and down is installed in the sedimentation tank.

In the first embodiment, by adding elements such as an isolation net and a vertical slide rail, when the isolation net moves downward, it can quickly isolate suspended substances to the bottom of the sedimentation tank, improving the accuracy of pumping water and reducing the waiting time for sedimentation. In the second embodiment, by using a water suction pipe with a hose structure and the setting of a moving mechanism, the water suction pipe can gradually lower its height as the depth of the wastewater in the sedimentation tank decreases, keeping the distance from the suspended substances at the bottom of the sedimentation tank as much as possible during the pumping process and reducing the suction force on the suspended substances.

Specific embodiments

[0021] The following combines the attached Figures 1-4 A further detailed description will be given to the specific embodiments of the present utility model.

[0022] Embodiment 1

[0023] A corrosion foil production wastewater treatment device includes a base 10 and a wastewater treatment tank 20, a sedimentation tank 30, a liquid transfer mechanism 40, a heating tank 50, a cooler 60, and a water tank 70 that are sequentially connected and arranged on the base 10. A drain pipe 21 is fixedly provided at the lower end of the wastewater treatment tank 20, and a wastewater inlet pipe is provided on the side surface of the upper end of the wastewater treatment tank 2. When producing corrosion foil, a cleaning liquid is required for cleaning, and the wastewater after cleaning enters the wastewater treatment tank 20 through the wastewater inlet pipe. Chemical agents are added to the wastewater through the upper end of the wastewater treatment tank 20, so that the chemical substances used for corrosion foil in the wastewater become solid impurities after treatment. The sedimentation tank 30 is used to hold solid impurities and liquid substances. After sedimentation for a period of time, the liquid transfer mechanism 40 is used to extract the liquid substances in the sedimentation tank 30 into the heating tank 50 for heating, so that the water in the liquid substances evaporates, and then the water vapor is cooled by the cooler 60 for recovery. Then, by opening the discharge pipe on the heating tank 50, the cleaning liquid used during the production of corrosion foil can be extracted. The above structure is a common structure of the existing corrosion foil production wastewater treatment device, so in this embodiment, no detailed description will be given. The key improvement points in this embodiment are:

[0024] The drain pipe 21 extends into the lower end inside the sedimentation tank 30, and an isolation net 80 is sleeved outside the drain pipe 21. The isolation net 80 can move up and down in the sedimentation tank 30, and the isolation net 80 always remains above the lower end of the drain pipe 21. The isolation net 80 is specifically arranged such that when the isolation net 80 slides to the lowermost position of the drain pipe 21, the liquid transfer mechanism 40 can pump the wastewater in the sedimentation tank 30 above the isolation net 80 into the heating tank 50.

[0025] The above structure will be described in detail below:

[0026] The wastewater and solid mixture in the wastewater treatment tank 20 are discharged into the sedimentation tank 30. After a short period of static settlement, the heavier solids will quickly settle to the bottom of the sedimentation tank 30, and there may still be a small amount of suspended matter floating in the sedimentation tank 30. At this time, by moving the isolation net 80 downward, the suspended matter that has not settled to the bottom can be quickly pushed and isolated at the bottom of the sedimentation tank 30, so that the solids and suspended matter settled at the bottom of the sedimentation tank 30 are below the isolation net 80, and the wastewater without solid impurities or suspended matter is above the isolation net 80. In this way, by pumping the wastewater from above the isolation net 80 through the transfer mechanism 40, it is possible to prevent pumping of solids or suspended impurities. Moreover, the isolation net 80 can push the suspended matter to move downward faster, and also reduces the waiting time for sedimentation.

[0027] A vertical slide rail 22 is fixed to the inner wall of the sedimentation tank 30, and the isolation net 80 is slidably connected to the vertical slide rail 22.

[0028] A driving mechanism 90 for driving the isolation net 80 to move up and down is installed in the sedimentation tank 30.

[0029] In this embodiment, the liquid transfer mechanism 40 includes a water pump 41 and a water suction pipe 42. The water pump 41 is fixedly arranged on the surface of the base 10 and the water outlet of the water pump 41 is connected to the inside of the heating tank 50. The water suction pipe 42 is fixedly connected to the water inlet of the water pump 41, and the lower end of the water suction pipe 42 extends vertically into the sedimentation tank 30. It can be understood that the water suction pipe 42 is a rigid structure, and the lower end height of the water suction pipe 42 is higher than the lower end height of the drain pipe 21. A through hole 81 for inserting the water suction pipe 42 is provided through the isolation net 80. In this way, at the beginning, the isolation net 80 is at a relatively high position in the sedimentation tank 30 as Figure 2 shown. The solid-liquid mixed wastewater reaches the bottom of the sedimentation tank 30 through the drain pipe 21. After a short period of static settlement, the isolation net 80 moves downward, isolating the solids and suspended matter below the sedimentation tank 30. Moreover, the isolation net 80 will also be separated from the lower end of the water suction pipe 42 and reach Figure 1 the state shown. At this time, the lower end of the water suction pipe 42 is above the isolation net 80, and the wastewater above the isolation net 80 is pumped out.

[0030] Further, a plugging assembly for plugging the through hole 81 is provided at the lower end of the sedimentation tank 30. The plugging assembly includes a plug rod 90. The lower end of the plug rod 90 is fixed to the lower end of the sedimentation tank 30. When the isolation net 80 slides to the lower end of the drain pipe 21, the water extraction pipe 42 is separated from the through hole 81, and the upper end of the plug rod 90 is inserted into the through hole 81. Through the arrangement of the plug rod 90, when the isolation net 80 moves downward, the through hole 81 will be plugged by the plug rod 90, so that the suspended matter will not be pumped out of the through hole 81 when the water extraction pipe 42 pumps water.

[0031] Embodiment 2

[0032] The structure of Embodiment 2 is substantially the same as that of Embodiment 1. The main improvement lies in that the liquid transfer mechanism 40 includes a water pump 41 and a water extraction pipe 42. The water extraction pipe 42 is of a flexible pipe structure. The water pump 41 is fixedly arranged on the surface of the base 10 and the water outlet of the water pump 41 is connected to the inside of the heating tank 50. One end of the water extraction pipe 42 is fixedly connected to the water inlet of the water pump 41, and the other end of the water extraction pipe 42 extends into the sedimentation tank 30. The sedimentation tank 30 is provided with a moving mechanism 100 for driving the lower end of the water extraction pipe 42 to move up and down in the sedimentation tank 30. In Embodiment 2, the isolation net 80 does not need to be provided with a through hole 81, and the plug rod 90 does not need to be provided at the bottom of the sedimentation tank 30 either. When in use, first, the solid matter and the suspended matter are isolated by the isolation net 80 to the bottom of the sedimentation tank 30, and then the moving mechanism 100 works to drive the other end of the water extraction pipe 42 connected to the water pump 41 to pump water gradually from top to bottom. The advantage of this is that when starting to pump water, the water extraction position of the water extraction pipe 42 is relatively far from the lower end of the sedimentation tank 30, which reduces the suction force on the suspended matter below the isolation net 80.

[0033] The moving mechanism 100 is an electric cylinder.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
