[0002] Polyferric sulfate is a high-performance inorganic polymeric coagulant. It is a pale yellow, amorphous powder that is highly soluble in water, producing a reddish-brown transparent aqueous solution. Polyferric sulfate is widely used in the purification of drinking water, industrial water, various industrial wastewaters, municipal sewage, and sludge dewatering.

[0003] Polyferric sulfate can be sold both as a solid powder and as a finished product in solution form. Typically, the solid powder is stored in the storage facility, and customers can choose to sell the solid powder directly or dilute it in water to form a finished solution, depending on their needs.

[0004] Because polyferric sulfate powder is hygroscopic, frequent opening and closing of the container storing polyferric sulfate can easily affect its performance. In addition, directly diluting and stirring polyferric sulfate into a solution in the factory can easily contaminate the solution during the dilution process, and the accuracy of the dilution ratio cannot be guaranteed. Utility Model Content

[0008] Furthermore, the central mixing cylinder includes a top area, a middle area, and a base area arranged sequentially. The outer diameter of the top area gradually increases towards the middle of the central mixing cylinder. The middle area has a square cross-section. The base area is located below the solid storage bin.

[0009] Further, the top surface of the top area is semispherical, the solid storage bin comprises a feeding section and a storage section, the feeding section is arranged around the top area, and the inner diameter of the feeding section is gradually reduced towards the top area.

[0010] Further, the bottom of each storage area is funnel-shaped, and a bottom plate capable of rotating towards the connecting pipeline is arranged at the connection between the storage area and the connecting pipeline.

[0011] Further, a slide rail is vertically arranged on the sidewall of each storage area, and the compression plate is slidably arranged on the slide rail.

[0012] Further, a dissolving cavity is arranged in the base area, the connecting pipeline is communicated with the dissolving cavity, a liquid outlet is arranged at the bottom of the base area, and the liquid outlet is communicated with the dissolving cavity.

[0013] Further, a stirring shaft is rotatably arranged at the top of the dissolving cavity.

[0014] Further, a screening device is arranged between the middle area and the base area, and the screening device can drive the top area and the middle area to shake.

The embodiments of the present application are shown in the drawings. However, the present application can be realized in many different forms, and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0027] As Figures 1 to 4As shown, a solid storage and solution generating device of polymeric ferric sulfate comprises a central mixing cylinder 1, the central mixing cylinder 1 comprises a top portion 11, a middle portion 12 and a base portion 13 from top to bottom, and the middle portion 12 is provided with a solid storage bin 2 for storing polymeric ferric sulfate powder. Specifically, the top surface of the top portion 11 is hemispherical, and the outer diameter of the top portion 11 gradually increases towards the middle portion 12, thereby forming an inclined side wall from the top to the bottom; the cross section of the middle portion 12 is square-shaped, so as to facilitate the compaction of the polymeric ferric sulfate powder in the subsequent step; the base portion 13 is located below the solid storage bin 2. The base portion 13 forms a dissolution cavity 131 inside, the polymeric ferric sulfate powder in the solid storage bin 2 is transported into the dissolution cavity 131, and water solution is introduced into the dissolution cavity 131, so as to form a polymeric ferric sulfate solution in the dissolution cavity 131. Further, the base portion 13 is provided with a liquid outlet 132 near the bottom region, the liquid outlet 132 is communicated with the dissolution cavity 131, and the polymeric ferric sulfate solution is discharged through the liquid outlet 132 after being prepared; a valve is arranged at the liquid outlet 132, which is not shown in the figure.

[0028] The solid storage bin 2 comprises a feeding section 24 and a storage section 25 from top to bottom, the feeding section 24 is surrounded by the top portion 11, and the inner diameter of the feeding section 24 gradually tightens towards the top of the top portion 11, and the port of the feeding section 24 is provided with a sealing cover, which is not shown in the figure, and the polymeric ferric sulfate powder is loaded into the solid storage bin 2 through the port of the feeding section 24.

[0029] The storage section 25 is surrounded by the middle portion 12, and a plurality of partitions 21 are fixedly arranged in the storage section 25, so as to divide the solid storage bin 2 into a plurality of storage areas 22; the bottom of each storage area 22 is funnel-shaped, and each storage area 22 is provided with a connecting pipeline 3, one end of the connecting pipeline 3 away from the storage area 22 is communicated with the dissolution cavity 131, so that the polymeric ferric sulfate powder stored in the storage area 22 can be transported into the dissolution cavity 131 through the connecting pipeline 3, and the funnel-shaped bottom of the storage area 22 enables the polymeric ferric sulfate powder in the storage area 22 to be discharged.

[0030] The side wall of each storage area 22 is vertically fixed with a slide rail 27, and a pressing plate 23 is slidably arranged on the slide rail 27, and the pressing plate 23 can also rotate relative to the side wall of the storage area 22. The device is provided with a control center and a driving device, which are prior art and will not be described in detail in this application. When the polymeric ferric sulfate powder is added into the solid storage bin 2, the pressing plate 23 can be driven to rotate to be attached to the side wall of the storage area 22; when the loading of the polymeric ferric sulfate powder is completed, the pressing plate 23 can be driven to rotate to a horizontal state, and then the pressing plate 23 is driven to move along the slide rail 27 until the polymeric ferric sulfate powder is compacted.

[0031] It should be noted that the storage area 22 is connected with the connecting pipe 3, and a bottom plate 26 capable of rotating towards the connecting pipe 3 is arranged at the connecting position of the storage area 22 and the connecting pipe 3. The storage or passage of the polymeric ferrous sulfate powder into the dissolving cavity 131 is realized by controlling the position of the bottom plate 26. The top of the dissolving cavity 131 is rotatably fixed with the stirring shaft 4. After the polymeric ferrous sulfate powder is passed into the dissolving cavity 131, an aqueous solution is added into the dissolving cavity 131, and the stirring shaft 4 is driven to rotate, so as to realize the sufficient dissolution of the polymeric ferrous sulfate and form the polymeric ferrous sulfate solution.

[0032] The design principle of the polymeric ferrous sulfate solid storage and solution generation device is as follows: the solid storage bin 2 is divided into a plurality of storage areas 22 by the partition plate 21, and the volume of each storage area 22 is fixed. Firstly, the polymeric ferrous sulfate powder is poured into the solid storage bin 2 through the port of the feeding section 24, and the top area 11 is arranged in a dome-shaped slope structure, so that the polymeric ferrous sulfate powder can be as evenly distributed as possible into each storage area 22. When the polymeric ferrous sulfate powder is dispersed and stored in each storage area 22, the control center is used to drive the pressing plate 23 to rotate to the horizontal state, and the pressing plate 23 is moved along the slide rail 27 until the polymeric ferrous sulfate in the storage area 22 is pressed tightly. The pressing force of the pressing plate 23 can be set, so that the compaction density of each storage area 22 is the same. Since the volume of each storage area 22 is the same and the compaction density is the same, the volume of the polymeric ferrous sulfate powder in the corresponding storage area 22 can be calculated according to the height of the pressing plate 23. The sieve device is arranged between the middle area 12 and the base area 13, and the sieve device can shake the top area 11 and the middle area 12. When the polymeric ferrous sulfate powder is loaded, the sieve device can make the polymeric ferrous sulfate powder better laid in the storage area 22, and also can reduce the polymeric ferrous sulfate powder adhered to the side wall of the central distribution cylinder 1. The sieve device is not shown in the figure.

[0033] When the polymeric ferrous sulfate solution needs to be prepared, the preparation concentration of the polymeric ferrous sulfate solution is set first, and the required amount of aqueous solution is calculated according to the volume of the polymeric ferrous sulfate powder in each storage area 22 and the preparation concentration. The bottom plate 26 of one storage area 22 is driven to rotate towards the connecting pipe 3 by the control center, the polymeric ferrous sulfate powder is passed into the dissolving cavity 131 through the connecting pipe 3, and the corresponding amount of aqueous solution is simultaneously passed into the dissolving cavity 131, and the stirring shaft 4 is started to realize sufficient stirring, so as to realize the polymeric ferrous sulfate solution with relatively accurate concentration. In the process of passing the polymeric ferrous sulfate powder into the dissolving cavity 131 through the connecting pipe 3, the sieve device can also be started to facilitate the polymeric ferrous sulfate powder to be exhausted.

[0034] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
