[0029] See also Figures 1 to 3 The above-mentioned waste liquid mixing and proportioning collection device includes a frame 100, a waste liquid collecting tank 110, a first material pouring operation platform 120, a second material pouring operation platform 121, a first waste liquid barrel platform 130, a second waste liquid barrel platform 131 and a waste liquid collection ton barrel 140.

[0030] See also Figure 1 and Figure 3 The frame 100 serves as a supporting structure of the collection device, and is used to provide installation space and support for other components. The frame 100 includes a middle area and two side areas. The middle area is used to install the waste liquid collection tank 110, and the two side areas are used to install the material pouring operation platform and the waste liquid barrel platform. Since the waste liquid is usually highly acidic or alkaline, the frame 100 is made of a material that is resistant to acid and alkali corrosion, and must also have sufficient strength to support each component. In one embodiment, the frame 100 is made of stainless steel.

[0031] See also Figure 1 and Figure 2 , the waste liquid collection tank 110 is arranged in the middle area of ​​the frame 100, and is used to collect and filter bulk waste liquid. In one embodiment, the waste liquid collection tank 110 includes a tank body and a filter screen 111, the tank body is fixedly mounted on the top of the frame 100, the filter screen 111 is detachably arranged inside the tank body, and is used to filter larger debris in the waste liquid and large particles at the bottom of the waste liquid barrel, and the filter screen 111 is detachably arranged in the tank body, and can be flexibly replaced according to different practical conditions, and can also be removed and cleaned when the filter screen 111 is blocked. The shape and size of the filter holes of the filter screen 111 are not limited, and can be selected according to actual needs. As an example, the mesh number of the filter screen 111 is 50 to 200 meshes, such as 50 meshes, 100 meshes, 150 meshes or 200 meshes. Further, the waste liquid collection tank 110 is made of stainless steel, and further, the waste liquid collection tank 110 is a 304 stainless steel square tank, so that the waste liquid collection tank 110 is acid-resistant and alkaline-resistant, and its service life is improved. The filter screen 111 is made of acid-resistant and alkali-resistant material, such as 304 stainless steel, 316 stainless steel, 316L stainless steel or polytetrafluoroethylene, etc.

[0032] In one embodiment, a partition 112 is provided in the waste liquid collection tank 110, and the partition 112 divides the waste liquid collection tank 110 into a first collection tank 113 and a second collection tank 114. The first collection tank 113 and the second collection tank 114 can be used to collect waste liquids of different components, for example, one collects acidic waste liquid and the other collects alkaline waste liquid. By mixing the waste liquids in the first collection tank 113 and the second collection tank 114 in a reasonable ratio, a mixed waste liquid that meets the treatment requirements can be obtained. Alternatively, one collects high-viscosity waste liquid and the other is used to add water to obtain a diluted waste liquid that meets the treatment requirements, and so on.

[0033] See also Figure 1 and Figure 2The first material pouring operation platform 120 and the second material pouring operation platform 121 are respectively arranged on the frame 100 on both sides of the waste liquid collection tank 110, and the first material pouring operation platform 120 and the second material pouring operation platform 121 are manual operation platforms. The first waste liquid barrel platform 130 and the second waste liquid barrel platform 131 are used to place small-package waste liquid barrels containing waste liquid. During use, standard pallets containing multiple layers of small-package waste liquid barrels are placed on the first waste liquid barrel platform 130 and the second waste liquid barrel platform 131. The first waste liquid barrel platform 130 is arranged on one side of the first material pouring operation platform 120 and is fixedly connected to the first material pouring operation platform 120, and the second waste liquid barrel platform 131 is arranged on one side of the second material pouring operation platform 121 and is fixedly connected to the second material pouring operation platform 121. The first waste liquid barrel platform 130 and the second waste liquid barrel platform 131 are steel structure placement platforms. An operator standing on the first material pouring operation platform 120 can lift the small package waste liquid barrel on the first waste liquid barrel platform 130 and place it on the waste liquid collection tank 110. An operator standing on the second material pouring operation platform 121 can lift the small package waste liquid barrel on the second waste liquid barrel platform 131 and place it on the waste liquid collection tank 110. Further, the first material pouring operation platform 120 and the second material pouring operation platform 121 are symmetrically arranged on both sides of the waste liquid collection tank 110, and the first waste liquid barrel platform 130 and the second waste liquid barrel platform 131 are symmetrically arranged at the front ends of the first material pouring operation platform 120 and the second material pouring operation platform 121.

[0034] The height of the first pouring operation platform 120 and the height of the second pouring operation platform 121 are lower than the height of the waste liquid collection tank 110. The height of the pouring operation platform can be determined according to the height of the waste liquid collection tank and the height of the lifting required by the natural standing bucket lifting posture of the human body to save physical effort, which is ergonomic when pouring materials manually. The height of the first waste liquid barrel platform 130 and the height of the second waste liquid barrel platform 131 are lower than the height of the first pouring operation platform 120 and the height of the second pouring operation platform 121. The height difference between the waste liquid barrel platform and the pouring operation platform is determined according to the height of the waste liquid barrel placed on the waste liquid barrel platform, so that a person standing on the pouring operation platform can extract the waste liquid barrel on the waste liquid barrel platform. The height difference between the material pouring operation platform and the waste liquid collection tank 110 and the height difference between the material pouring operation platform and the waste liquid barrel platform are ergonomic. The operator standing on the material pouring operation platform can directly lift the waste liquid barrel on the waste liquid barrel platform, place it on the waste liquid collection tank 110, and pour it directly without bending over to operate, thus avoiding fatigue caused by long-term manual bending. The processing time for a single barrel is about 3 minutes, and the single-sided material pouring operation platform can pour up to 3 to 5 barrels at the same time, which greatly improves labor efficiency and shortens operation time.

[0035] Since the material pouring operation platform has a certain height, in order to facilitate the operator to go up and down the material pouring operation platform, a ladder 123 is provided on the frame 100 below the first material pouring operation platform 120 and below the second operation platform 121. The ladder 123 can be set in front of, behind or on the side of the material pouring operation platform. Further, a guardrail 122 is provided on the frame 100 above the first material pouring operation platform 120 and above the second material pouring operation platform 121. The guardrail 122 is set around the material pouring operation platform to prevent the operator from falling from the material pouring operation platform and causing accidental injury.

[0036] See also Figure 1 The waste liquid collection barrel 140 is arranged directly below the waste liquid collection tank 110 to collect the proportioned waste liquid. The waste liquid collection barrel 140 adopts a standard corrosion-resistant barrel. Furthermore, a leakproof tray 141 is provided at the bottom of the waste liquid collection barrel 140. The leakproof tray 141 can be used to receive the waste liquid overflowing from the waste liquid collection barrel 140 to prevent the waste liquid from overflowing and causing damage to the on-site environment.

[0037] See also Figure 1 and Figure 3 In one embodiment, a waste liquid collection funnel 150 is provided between the waste liquid collection ton barrel 140 and the waste liquid collection tank 110. The waste liquid collection funnel 150 is fixed below the waste liquid collection tank 110, and the discharge port of the waste liquid collection funnel 150 faces the waste liquid collection ton barrel 140. The waste liquid collected by the waste liquid collection tank 110 after filtration enters the waste liquid collection ton barrel 140 through the waste liquid collection funnel 150. Furthermore, the waste liquid collection funnel 150 adopts a 304 stainless steel four-sided cone bucket, and the taper angle (the angle between the inclined surface and the horizontal plane) θ of the waste liquid collection funnel 150 can meet the waste liquid self-flow, that is, the taper angle of the waste liquid collection funnel 150 meets the waste liquid after pouring into the waste liquid collection ton barrel 140. It should be noted that the value of θ can be set according to actual conditions. As an example, θ can be 23° to 30°, for example, θ can be 23°, 25°, 28° or 30°, etc. This taper angle can achieve the self-flow of most of the waste liquid, while not causing the height of the waste liquid collection tank 110 to be too high due to too large a taper.

[0038] In one embodiment, the waste liquid collection funnel 150 is also provided with a telescopic device, which includes a telescopic opening 151 and an adjusting device. The telescopic opening 151 is provided at the discharge port of the waste liquid collection funnel 150. The adjusting device is used to adjust the telescopic opening 151. The adjusting device can adopt any structure that can adjust the telescopic opening 151. As an example, the adjusting device in this embodiment includes a rocker arm 152 and a connecting line 153. The rocker arm 152 is provided at one side of the waste liquid collection funnel 150 and is connected to the telescopic opening 151 through the connecting line 153. Rotating the rocker arm 152 can drive the telescopic opening 151 to move up and down through the connecting line 153 to adjust the distance between the telescopic opening 151 and the waste liquid collection barrel 140. When injecting liquid, the telescopic opening 151 is extended into the waste liquid collection barrel 140 through the rocker arm 152 to prevent the waste liquid from splashing out; after the injection is completed, the telescopic opening 151 is shaken out of the waste liquid collection barrel 140 through the rocker arm 152 to transfer the waste liquid collection barrel 140 to the treatment system.

[0039] The use process of the waste liquid mixing ratio collection device of the utility model is as follows:

[0040] The operator enters the first material discharging operation platform 120 or the second material discharging operation platform 121 through the ladder 123, rotates the rocker 152 to swing down the telescopic opening 151 so that it extends into the waste liquid collection barrel 140; uses a forklift to place a standard pallet with multiple layers of small-package waste liquid barrels stacked on the first waste liquid barrel platform 130 and / or the second waste liquid barrel platform 131, and the operator lifts the small-package waste liquid barrels on the first waste liquid barrel platform 130 and / or the second waste liquid barrel platform 131 and places them on the waste liquid collection tank 110, tilts and pours out the waste liquid, and the waste liquid is filtered through the waste liquid collection tank 110 and enters the waste liquid collection barrel 140 through the waste liquid collection funnel 150. The waste liquid mixing and proportioning collection device of the utility model can be used for mixing and proportioning of acid and alkali waste liquids, diluting waste liquids with high solid content, and mixing of small-package waste liquids, etc. The first collecting tank 113 and the second collecting tank 114 of the waste liquid collecting tank 110 can collect waste liquid respectively to classify and proportion it, so as to more finely control the composition of the waste liquid.

[0041] It should be noted that before the waste liquids are mixed, the ratio of different waste liquids needs to be calculated according to the quality of the waste liquids to be treated (such as acidity, alkalinity, solid content, etc.) and the hazardous waste treatment standards, and then different waste liquids are poured into the first collection tank 113 and the second collection tank 114 on the first and second material pouring operation platforms according to the calculated ratios. In addition, since the waste liquids are usually strong acids, strong alkalis, and other waste liquids with certain hazards, when mixing the waste liquids, the operators need to be equipped with protective tools, such as protective masks, protective gloves, etc.

[0042] The utility model symmetrically arranges the pouring operation platform and the waste liquid bucket platform on both sides of the waste liquid collection tank, which can realize the separate proportioning of different types of waste liquids, realize the acid-base neutralization of the waste liquid proportioning, and the dilution treatment of high-viscosity waste liquid, improve the efficiency of waste liquid mixing proportioning collection, and save the intermediate conveying equipment, reducing the system failure rate. Therefore, the utility model effectively overcomes some practical problems in the prior art and has high utilization value and use significance.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
