Description

Technical Field

[0001] This utility model relates to the field of aluminum ferric chloride processing technology, specifically to a mixing device for polyaluminum ferric chloride. Background Technology

[0002] In the production and application of polyaluminum ferric chloride (PAFC), the mixing equipment is a key link, and its performance directly affects the product quality and treatment effect. As a new type of inorganic polymer coagulant, polyaluminum ferric chloride is produced by the hydrolysis and polymerization reaction of aluminum salt and iron salt. It combines the advantages of aluminum salt and iron salt, and has the characteristics of fast hydrolysis speed, dense flocs, fast settling speed, and wide applicability. It shows significant advantages in the field of wastewater treatment. However, traditional mixing equipment often faces problems such as low heating efficiency, uneven stirring, easy powder adhesion, and inaccurate temperature control when treating polyaluminum ferric chloride. These problems not only affect production efficiency, but may also lead to unstable product quality.

[0003] In existing polyaluminum ferric chloride production processes, uneven mixing can lead to reduced production efficiency. During the feeding process, large quantities of raw materials are directly added into the reactor. After the large amount of material enters the reactor and is stirred again to homogenize it, some materials will clump when they come into contact with the liquid raw materials inside the reactor, especially when large quantities of material are directly added, which will cause a large amount of clumping. To address this, a mixing device for polyaluminum ferric chloride is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a mixing device for polyaluminum ferric chloride to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for polyaluminum ferric chloride, comprising: a reaction vessel, a positioning structure fixedly connected to the outside of the reaction vessel, a material cylinder installed on one side of the positioning structure, a feeder connected to the material cylinder, a telescopic structure installed below the positioning structure, an elastic dispersion column fixedly connected to the telescopic end of the telescopic structure, the elastic dispersion column being located at the outlet end of the material cylinder, and a gas supply structure installed on the positioning structure;

[0006] The air supply structure includes a bidirectional air pump installed on the positioning structure. The air outlet of the bidirectional air pump is connected to a flow divider box. A flow divider structure is installed on the outside of the flow divider box. The flow divider structure is connected to the elastic dispersion column and is used to continuously fill the interior of the elastic dispersion column with gas, causing the elastic dispersion column to expand. The expanded elastic dispersion column blocks the outlet of the material cylinder. The expanded elastic dispersion column is conical.

[0007] As a further preferred embodiment of this technical solution: the positioning structure includes a fixing plate, which is fixedly connected to the outer wall of the reactor. A hydraulic cylinder is fixedly connected to the fixing plate, and the end of the telescopic rod of the hydraulic cylinder is rotatably connected to the positioning plate. The bidirectional air pump is located on the positioning plate, and the material cylinder is fixedly connected to the end of the positioning plate away from the hydraulic cylinder.

[0008] As a further preferred embodiment of this technical solution: the telescopic structure includes a lower connecting rod, which is fixedly connected to the bottom of the positioning plate. A sliding sleeve is fixedly connected to the outside of the lower connecting rod, and a sliding sleeve rod is slidably connected inside the sliding sleeve. The elastic dispersion column is fixedly connected to the sliding sleeve rod.

[0009] As a further preferred embodiment of this technical solution: the gas supply structure includes a plurality of first electrically controlled valves connected to the outside of the diversion box, one of which is connected to a delivery pipe. The end of the delivery pipe away from the first electrically controlled valve passes through the interior of the lower connecting rod and is connected to a push bladder. The push bladder is located inside the sliding sleeve. One side of the sliding sleeve is fixedly connected to the outside of the push bladder. The outside of the push bladder is connected to a second electrically controlled valve. The end of the second electrically controlled valve away from the push bladder is connected to a diversion pipe. One end of the diversion pipe passes through the outer wall of the sliding sleeve and is connected to the elastic dispersion column.

[0010] As a further preferred embodiment of this technical solution: the end of the diverter pipe away from the second solenoid valve is connected to a three-way valve, one of the air outlets of the three-way valve is connected to the elastic dispersion column, and the other air outlet is connected to an external expansion airbag.

[0011] As a further preferred embodiment of this technical solution, the external expansion airbag has multiple flow channels on its exterior.

[0012] As a further preferred embodiment of this technical solution, the elastic dispersion column is internally fixedly connected with an elastic support.

[0013] As a further preferred embodiment of this technical solution: a steering motor is fixedly connected inside the hydraulic cylinder, and the output shaft end of the steering motor is fixedly connected to the bottom of the positioning plate.

[0014] As a further preferred embodiment of this technical solution: the outlet of another of the first electrically controlled valves is connected to the material cylinder via a one-way pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, an elastic dispersion column is set below the opening of the barrel. The elastic dispersion column is expanded into a cone shape by the gas supply structure and the diversion structure. After the raw material comes into contact with the cone surface of the elastic dispersion column, it is dispersed and falls into the reactor. The cone angle can be changed by supplying different amounts of gas into the elastic dispersion column, thereby controlling the position of the raw material falling into the reactor. This can effectively improve the uniformity of the raw material falling, reduce the occurrence of a large amount of agglomeration, ensure the quality stability of polyaluminum ferric chloride products, and improve production efficiency.

[0017] 2. In this utility model, gas can be delivered to the outer expansion airbag through the three-way valve to further expand the dispersion range of the material. The elastic support set inside the elastic dispersion column can form a better sealing effect on the discharge port of the material cylinder when a large amount of gas is continuously introduced. At the same time, it plays the role of pressing the material and clearing the material cylinder. Gas can also be injected into the material cylinder through another first electric control valve to pressurize the gas and push the material to be sprayed out quickly through the material cylinder, reducing the blockage of the material cylinder discharge port and achieving the effect of quickly dispersing the material.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example 1

[0027] Please see Figures 1-6 This utility model provides a technical solution: a mixing device for polyaluminum ferric chloride, comprising: a reaction vessel 1, a positioning structure fixedly connected to the outside of the reaction vessel 1, a material cylinder 5 installed on one side of the positioning structure, a feeder connected to the material cylinder 5, a telescopic structure installed below the positioning structure, an elastic dispersion column 9 fixedly connected to the telescopic end of the telescopic structure, the elastic dispersion column 9 being located at the outlet end of the material cylinder 5, and a gas supply structure installed on the positioning structure.

[0028] The air supply structure includes a bidirectional air pump 10 installed on the positioning structure. The air outlet of the bidirectional air pump 10 is connected to a diversion box 11. A diversion structure is installed on the outside of the diversion box 11. The diversion structure is connected to the elastic dispersion column 9 and is used to continuously fill the interior of the elastic dispersion column 9 with gas, causing the elastic dispersion column 9 to expand. The expanded elastic dispersion column 9 blocks the outlet of the material cylinder 5. The expanded state of the elastic dispersion column 9 is conical.

[0029] In this embodiment, specifically: during use, the operator injects aluminum ferric chloride raw material into the cylinder 5. As material is continuously injected into the cylinder 5, it continuously transports the aluminum ferric chloride raw material to the reactor 1 located below. During material transport, the elastic dispersion column 9, located below the opening of the cylinder 5, is adjusted to the lower opening of the cylinder 5 via a telescopic structure. Gas is then transported into the elastic dispersion column 9 through a gas supply and diversion structure, causing the elastic dispersion column 9 to expand. This conical expansion allows the raw material transported through the cylinder 5 to contact the conical surface of the elastic dispersion column 9, thus dispersing it into the reactor 1. Furthermore, different amounts of gas can be supplied to the elastic dispersion column 9 during continuous transport, causing varying degrees of taper in the elastic dispersion column 9. By controlling the taper, the position of the raw material falling into the reactor 1 is adjusted, further controlling the uniformity of the raw material falling into the reactor 1 and reducing the phenomenon of excessive agglomeration.

[0030] like Figures 1-3 As shown, the positioning structure includes a fixing plate 2, which is fixedly connected to the outer wall of the reactor 1. A hydraulic cylinder 3 is fixedly connected to the fixing plate 2. The end of the telescopic rod of the hydraulic cylinder 3 is rotatably connected to a positioning plate 4. A bidirectional air pump 10 is located on the positioning plate 4. A material cylinder 5 is fixedly connected to the end of the positioning plate 4 away from the hydraulic cylinder 3. A steering motor 21 is fixedly connected inside the hydraulic cylinder 3. The end of the output shaft of the steering motor 21 is fixedly connected to the bottom of the positioning plate 4.

[0031] In this embodiment, specifically: during use, the operator can activate the hydraulic cylinder 3 to adjust the vertical position of the material cylinder 5, thereby preventing the water flow from being guided to the outside by the elastic dispersion column 9 when the fluid raw material enters. In addition, the operator can activate the steering motor 21 to rotate the positioning plate 4 as a whole, thereby rotating and adjusting the material cylinder 5 and the elastic dispersion column 9 to the external position of the reaction vessel 1.

[0032] like Figures 1-5 As shown, the telescopic structure includes a lower connecting rod 6, which is fixedly connected to the bottom of the positioning plate 4. A sliding sleeve 7 is fixedly connected to the outside of the lower connecting rod 6, and a sliding sleeve rod 8 is slidably connected inside the sliding sleeve 7. An elastic dispersion column 9 is fixedly connected to the sliding sleeve rod 8.

[0033] In this embodiment, specifically: during use, the bidirectional air pump 10 diverts gas through the diversion box 11 and the first solenoid valve 12 to the inside of the delivery pipe 13, and the delivery pipe 13 delivers the gas to the inside of the push bladder 14. When gas accumulates inside the push bladder 14, the second solenoid valve 15 is closed, allowing gas to accumulate inside the push bladder 14. When gas accumulates inside the push bladder 14, it can push the sliding sleeve 8 to move inside the sliding sleeve 7, forming a pneumatic telescopic effect.

[0034] like Figures 1-3 As shown, the gas supply structure includes multiple first electrically controlled valves 12 connected to the outside of the diversion box 11. One of the first electrically controlled valves 12 is connected to a delivery pipe 13. The end of the delivery pipe 13 away from the first electrically controlled valve 12 passes through the interior of the lower connecting rod 6 and is connected to a push bladder 14. The push bladder 14 is located inside the sliding sleeve 7. One side of the sliding sleeve 8 is fixedly connected to the outside of the push bladder 14. The outside of the push bladder 14 is connected to a second electrically controlled valve 15. The end of the second electrically controlled valve 15 away from the push bladder 14 is connected to a diversion pipe 16. One end of the diversion pipe 16 passes through the outer wall of the sliding sleeve 8 and is connected to the elastic dispersion column 9.

[0035] In this embodiment, specifically: in the gas supply structure, the gas is transported to the inside of the diversion box 11 by the bidirectional air pump 10. The multiple first solenoid valves 12 outside the diversion box 11 can respectively transport the gas to the inside of the delivery pipe 13 or the one-way pipe. When the gas enters the inside of the delivery pipe 13, the gas can be diverted to the push bladder 14, the second solenoid valve 15 and the elastic dispersion column 9 to complete the gas delivery and supply.

[0036] Example 2

[0037] Considering that during use, when the material falls naturally onto the conical surface of the elastic dispersion column 9, the resulting dispersion force is weak, and the dispersion range can only be adjusted according to the volume of the elastic dispersion column 9, and that excessive gas entering the elastic dispersion column 9 may block the outlet of the material cylinder 5, thus failing to achieve a good dispersion effect, the following technical solution is proposed to solve the above technical problems:

[0038] like Figures 1-4 As shown, the end of the diversion pipe 16 away from the second solenoid valve 15 is connected to a three-way valve 17. One of the air outlets of the three-way valve 17 is connected to the elastic dispersion column 9, and the other air outlet is connected to the external expansion airbag 18.

[0039] In this embodiment, specifically: by setting the three-way valve 17, gas can be delivered to the interior of the outer expansion airbag 18. After the gas is delivered to the interior of the outer expansion airbag 18, the outer expansion airbag 18 can expand. The expansion mode of the outer expansion airbag 18 is flat expansion, which can further extend the conical surface of the elastic dispersion column 9 and expand the dispersion range of the material.

[0040] In this embodiment, specifically: the external expansion airbag 18 has multiple flow channels 20. When the external expansion airbag 18 expands, if the gas wants to enter the interior of the elastic dispersion column 9, the gas output from another outlet of the three-way valve 17 can be transported to the interior of the elastic dispersion column 9 through the flow channels 20.

[0041] In this embodiment, specifically: an elastic support 19 is fixedly connected inside the elastic dispersion column 9. The elastic support 19 can support the elastic dispersion column 9. When it is necessary to use the elastic dispersion column 9 to block the outlet of the material cylinder 5, gas can be continuously supplied into the elastic dispersion column 9. When a large amount of gas continuously enters the elastic dispersion column 9, it will also expand upward, thereby forming a better blocking effect on the outlet of the material cylinder 5 in conjunction with the elastic support 19. At the same time, when the elastic dispersion column 9 enters the outlet of the material cylinder 5, it can also form a pressing effect on the material, forming a through effect on the outlet of the material cylinder 5, thereby clearing the material cylinder 5.

[0042] like Figure 1 As shown, the outlet of another first electrically controlled valve 12 is connected to the material cylinder 5 through a one-way pipe.

[0043] In this embodiment, specifically: when the material cylinder 5 is discharging material, another first solenoid valve 12 can be used to continuously inject gas into the interior of the material cylinder 5 through a one-way pipe to pressurize the gas, thereby further pushing the material to be quickly ejected out of the material cylinder 5, reducing the phenomenon of blockage at the outlet of the material cylinder 5.

[0044] Working Principle: Operators inject aluminum ferric chloride raw material into the feed cylinder 5, which continuously transports the material to the reactor 1 located below. During material transport, the elastic cylindrical dispersion column 9, located below the opening of the feed cylinder 5, is adjusted to the lower opening of the feed cylinder 5 via a telescopic structure. The gas supply and distribution structures deliver gas into the elastic cylindrical dispersion column 9, causing it to expand into a cone shape. The raw material, upon contacting the conical surface of the elastic cylindrical dispersion column 9, is dispersed and falls into the reactor 1. By supplying different amounts of gas into the elastic cylindrical dispersion column 9, its cone angle can be changed, thereby controlling the position of the raw material falling into the reactor 1, improving the uniformity of the material's fall, and reducing agglomeration.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
