Description

Technical Field

[0001] This utility model relates to the field of PAC mixing technology, specifically to a mixing device for PAC solutions. Background Technology

[0002] Polyaluminum chloride (PAC) is also commonly known as a water purifier or coagulant. It is a water-soluble inorganic polymer between AlCl3 and Al(OH)3, with the general chemical formula [Al2(OH)NCl6-NLm], where m represents the degree of polymerization and n represents the neutrality of the PAC product.

[0003] Chinese patent document CN217492101U discloses a high-efficiency PAC reaction tank. This device uses a crushing mechanism to crush vegetables in segments, allowing the vegetables to react more quickly with the PAC solution and rapidly extract harmful substances from them, thus improving the low efficiency of traditional PAC reaction tanks.

[0004] While the aforementioned patent can improve the efficiency of the PAC reaction tank, the original equipment cannot simultaneously output PAC solution while outputting the drug solution. This results in a waiting process when multiple devices need to extract PAC solution. To overcome the above shortcomings, a more convenient mixing device for PAC solution is proposed in this utility model. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 and Figure 2 A mixing device for PAC solution includes a tank 1, a mounting cover 2, a drive motor 3, a sensor 4, a test crystal 5, a stirring shaft 6, a dispensing device 7, and a discharge pipe 8. The mounting cover 2 is mounted on the top of the tank 1. The drive motor 3 is fixed to the top of the mounting cover 2 and is connected to the top of the stirring shaft 6 via a coupling. The sensor 4 is fixed to the left end of the tank 1 and is electrically connected to the left end of the test crystal 5, which is installed inside the left end of the tank 1. The stirring shaft 6 is rotatably connected to the bottom of the mounting cover 2. The dispensing device 7 is fixed to the right end of the tank 1. The discharge pipe 8 is located on the top of the mounting cover 2.

[0027] In this implementation case: the connection between tank 1 and mounting cover 2 is fixed by threaded bolts, which makes it detachable.

[0028] Please see Figure 3 and Figure 4 A mixing and dispensing device 7 for PAC solution includes a fixing block 71, a housing 72, a dispensing box 73, an outlet pipe 74, a drive motor 75, a power transmission shaft 76, a telescopic plug 77, and a transmission connecting rod 78. The fixing block 71 is fixed to the right end of the tank 1, and the housing 72 is fixed to the right end of the fixing block 71. The top of the housing 72 is connected to the right end of the tank 1. The dispensing box 73 is located at the bottom of the housing 72. The outlet pipe 74 is welded and fixed to the right end of the dispensing box 73. The drive motor 75 is connected to the front end of the housing 72. The drive motor 75 is connected to the front end of the power transmission shaft 76 via a coupling. The power transmission shaft 76 is nested with the top of the transmission connecting rod 78 for transmission. The transmission connecting rod 78 is connected to the top of the telescopic plug 77 for transmission. The telescopic plug 77 is in sliding fit with the inside of the dispensing box 73.

[0029] In this embodiment: the left end of the fixed block 71 is arc-shaped, and the left end of the fixed block 71 is fitted into the tank 1. The cross-section of the telescopic plug 77 is larger than the cross-section of the outlet pipe 74, so that the telescopic plug 77 can block the outlet pipe 74 and thus limit the output flow of the outlet pipe 74. There are three sets of transmission connecting rods 78, and the three sets of transmission connecting rods 78 are equidistantly mounted on the power transmission shaft 76.

[0030] Please see Figure 5A mixing device for PAC solution, the transmission linkage 78 includes a transmission sleeve 781, a swing arm 782, an output shaft 783, a transmission arm 784, and a connecting shaft 785. The transmission sleeve 781 is nested with the outer side of the power transmission shaft 76. The transmission sleeve 781 is located at the left end of the swing arm 782. The swing arm 782 is connected to the top of the transmission arm 784 via the output shaft 783. The transmission arm 784 is connected to the top of the telescopic plug 77 via the connecting shaft 785.

[0031] In this implementation case: the output shaft 783 and the connecting shaft 785 are the same size and are common shaft accessories. During the assembly process, their function is to prevent interference when the swing arm 782 drives the transmission arm 784.

[0032] In summary, during use, the raw materials and water are placed into the tank 1 through the discharge pipe 8. The drive motor 3 is started to drive the stirring shaft 6 to rotate, causing the stirring shaft 6 to stir and mix the raw materials and water inside the tank 1. PAC solution is then produced inside the tank 1. During this process, the quality of the PAC solution can be detected by the sensor 4 and the test crystal 5, which makes it convenient for the staff to record the solution status.

[0033] Subsequently, when PAC flows in from the top of the housing 72, the power transmission shaft 76 is driven to rotate by the drive motor 75. This causes the power transmission shaft 76 to rotate the transmission sleeve 781 through a nested arrangement. The swing arm 782 on the outer side of the transmission sleeve 781 rotates accordingly, and the transmission arm 784 pulls the telescopic plug 77 to extend and retract. This allows the telescopic plug 77 to work with the outlet pipe 74 to control the flow rate of the output PAC solution, ensuring that each set of outlet pipes 74 can output PAC solution evenly and quickly. This achieves the goal of dispensing PAC solution through the dispensing device 7 while maintaining the efficiency of PAC solution dispensing. This allows each batch of dispensing work to be completed at the same time, thus solving the problem of waiting when multiple devices need to extract PAC solution in the original equipment.
