[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] Combine the following Figures 1 to 5 A liquid flocculant preparation device according to an embodiment of the present invention is described.

[0027] The liquid flocculant preparation device according to the embodiment of the present invention comprises a material box 100, a preparation box 200, a storage box 300 and a delivery system 400 which are connected in sequence. The material box 100 contains flocculant raw materials. A mixing drum 210 for mixing liquid flocculant and water is arranged on the upper part of the preparation box 200. The mixing drum 210 is connected to the material box 100 through a first pipe 110 and flocculant is added into the mixing drum 210 through a first pump 120. The mixing drum 210 is connected to the preparation box 200 to mix the mixed flocculant and water. The flocculant is output to the preparation box 200; the storage box 300 is connected with the preparation box 200 through the second pipe 310, and the material box 100 and the preparation box 200 are both arranged above the storage box 300; the storage box 300 is connected with the bottom of the preparation box 200 through the second pipe 310, and the material box 100 and the preparation box 200 are both arranged above the storage box 300; the delivery system 400 is connected with the storage box 300 and the flocculant in the storage box 300 is pumped out by the third pump and mixed with water before delivery.

[0028] It is understandable that the existing flocculant preparation device usually does not use a pump to transport the material because the raw material is a solid dry powder. At the same time, the first pump 120 usually uses a diaphragm pump for transportation. Compared with other types of pumps, the diaphragm pump has low shear force and little physical impact on the material, and is particularly suitable for transporting flocculants.

[0029] For example, refer to Figure 1 , the material box 100 and the preparation box 200 are both arranged on the top of the storage box 300, as shown in FIG. Figure 3As shown, the material box 100 is arranged at the lower left corner of the upper surface of the storage box 300, and the preparation box 200 is arranged at the right half of the upper surface of the storage box 300. The first pipe 110 is connected from the top of the material box 100 to the top of the preparation box 200, and the first pump 120 on the first pipe 110 is fixed at the junction of the preparation box 200 and the material box 100. Usually, the preparation box 200 is also provided with a support component for supporting the first pipe 110 to prevent the first pipe 110 from deforming due to its own gravity. The storage box 300 is connected to the preparation box 200 through the second pipe 310. In order to save space, the second pipe 310 is arranged at the upper left corner of the top of the storage box 300, one end of which is connected to the low point in the preparation box 200, and the other end is connected to the top of the storage box 300, so that the flocculant prepared in the preparation box 200 can be transferred to the storage box 300 for storage. It can be understood that a valve for controlling its on and off is provided on the second pipe 310, so as to better control the flow of liquid. The dosing system 400 is disposed on the side of the storage tank 300 , and the flocculant in the storage tank 300 is pumped out and transported through the second pump 410 .

[0030] According to some specific embodiments of the present invention, an overflow cylinder 220 is provided in the mixing cylinder 210, a first water injection port 230 is provided on the side wall of the mixing cylinder 210, and the outlet of the first pipeline 110 is provided between the overflow cylinder 220 and the mixing cylinder 210, the upper end of the overflow cylinder 220 is higher than the bottom surface of the mixing cylinder 210, and the flocculant mixed in the mixing cylinder 210 flows out from the overflow cylinder 220. For example, referring to Figure 2 The outlet of the first pipe 110 is vertically downward, so that the flocculant can flow out after being mixed between the overflow tube 220 and the mixing tube 210, preventing the flocculant from flowing out directly from the overflow tube 220. After the water and flocculant are mixed, they need to enter the overflow tube 220 from the top of the overflow tube 220 and be output. In other words, the flocculant and water mixed in the mixing tube 210 need to reach a certain amount before they can be transported to the preparation box 200. In this way, the flocculant and water can be fully mixed, the mixing accuracy can be better controlled, and concentration deviation can be avoided.

[0031] According to some specific embodiments of the present invention, the first water injection port 230 injects water into the mixing cylinder 210 along the tangent direction of the overflow cylinder 220. The first water injection port 230 injects water from the horizontal tangent direction, and the water flow injected from the tangent will form a vortex, so that the water and the flocculant are mixed more fully and the mixing effect is better.

[0032] According to some specific embodiments of the present invention, the outlet of the first pipe 110 and the first water injection port 230 are both located below the height of the overflow tube 220. Figure 3In order to prevent water and flocculant from splashing out of the overflow cylinder 220 without being mixed, the outlet of the first pipe 110 and the first water injection port 230 are both lower than the upper end of the overflow cylinder 220. When the mixing cylinder 210 is mixing, liquid will always remain between the outer wall of the overflow cylinder 220 and the mixing cylinder 210, so that the outlet of the first pipe 110 and the first water injection port 230 will directly connect the liquid, avoiding liquid splashing and ensuring the mixing accuracy.

[0033] According to some specific embodiments of the present invention, a mixing bucket 240 and a water injection cylinder 290 mounted outside the mixing bucket are connected to the overflow cylinder 220, and a closed water injection chamber 250 is formed between the mixing bucket 240 and the water injection cylinder 290. The interior of the mixing bucket 240 is connected to the overflow cylinder 220 to receive the flocculant flowing down from the overflow cylinder 220. A plurality of injection holes 260 are arranged on the inclined surface of the mixing bucket 240, and the water injection chamber 250 is provided with a second water injection port 270. For example, referring to Figure 3 A mixing bucket 240 is connected and arranged below the overflow cylinder 220. The mixing bucket 240 has a small upper opening and a large lower opening. A closed water injection chamber 250 is formed between the mixing bucket 240 and the water injection cylinder 290. A plurality of injection holes 260 are arranged on the inclined surface of the mixing bucket 240. The injection holes 260 are evenly distributed around the central axis of the mixing bucket 240. The water injection chamber 250 is provided with a second water injection port 270. The second water injection port 270 injects water into the water injection chamber 250. When the water in the water injection chamber 250 is injected into the mixing bucket 240 from the injection hole 260. The upper opening of the mixing bucket 240 is connected to the overflow cylinder 220. After the water and flocculant are mixed and diluted for the first time in the overflow cylinder 220, they flow into the mixing bucket 240, and then they are mixed and diluted for the second time with the water injected from the injection hole 260. Finally, the required flocculant is obtained and flows into the preparation box 200.

[0034] It is understandable that the overflow cylinder 220 and the mixing bucket 240 can be designed as an integral body, but a partition is required in the middle to separate the mixing cylinder 210 into two upper and lower cavities, for example Figure 3 In the upper half of the mixing cylinder 210, the flocculant and water are mixed and flow into the overflow cylinder 220 from the upper opening. In the lower half of the mixing cylinder 210, the water injection chamber 250 is filled with water, which does not directly contact the flocculant mixture in the upper half, but merges with the flocculant flowing down from the overflow cylinder 220 through the injection hole 260.

[0035] According to some specific embodiments of the present invention, one end of the first pipe 110 connected to the material box 100 extends into the lowest point in the material box 100 and is provided with a filter check valve. Figure 1One end of the first pipe 110 disposed in the material box 100 extends into the bottom of the material box 100 to ensure that the material at the lowest point of the material box 100 can be drawn out. The filter check valve can filter debris to prevent impurities in the flocculant raw material from entering the preparation process. At the same time, the filter check valve can prevent backflow, which is more convenient for high-precision control.

[0036] According to some embodiments of the present invention, the first pipe 110 is provided with an injection valve facing downward at one end in the mixing barrel 210, for example, referring to Figure 2 Since one end of the first pipe 110 in the mixing barrel 210 is immersed in the liquid for a long time, an injection valve is required to prevent the liquid from flowing back and affecting the liquid concentration in the material box 100. At the same time, the injection valve can also better perform precision control.

[0037] According to some embodiments of the present invention, a stirring device 280 is provided in the preparation box 200, for example, referring to Figure 4 The stirring device 280 is mainly a stirring rod driven by a motor, which stirs the flocculant in the preparation box 200 to prevent the flocculant from settling and causing uneven concentration, and also further promotes the mixing of the flocculant and water.

[0038] According to some embodiments of the present invention, the second pump 410 is a screw pump, for example, Figure 5 The delivery system 400 is connected to the storage box 300 through the second pump 410. The screw pump has a wider flow channel and a better transportation effect.

[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
