Description

Technical Field

[0001] This utility model relates to the field of liquid polyaluminum chloride technology, and in particular to an automatic preparation device for liquid polyaluminum chloride. Background Technology

[0002] The automatic liquid polyaluminum chloride preparation device is a piece of equipment that can automatically prepare liquid polyaluminum chloride. It can accurately control parameters such as raw material dosage and reaction conditions, and realize automatic stirring, mixing, reaction and solution preparation to ensure the stable quality of the prepared liquid polyaluminum chloride and meet the needs of the water treatment field.

[0003] In existing technologies, automatic liquid polyaluminum chloride (PAC) preparation devices typically monitor parameters such as water flow rate using sensors, and precisely control the amount of PAC added using metering pumps according to a set ratio. They can also use stirring devices to ensure thorough mixing and automatically adjust the dosage based on changes in water quality to ensure the preparation effect.

[0004] However, in the existing technology, some automatic preparation devices for liquid polyaluminum chloride require the slow addition of calcium aluminate powder to hydrochloric acid of a certain concentration. Therefore, it is necessary to add calcium aluminate powder quantitatively during the production process to ensure that the calcium aluminate powder reacts fully with the hydrochloric acid. To address this issue, an automatic preparation device for liquid polyaluminum chloride is proposed. Utility Model Content

[0009] As a further description of the above technical solution: a support plate three is fixedly connected inside the support frame, a support plate four is fixedly connected inside the support frame, a mixing barrel is fixedly connected to the top of the support plate four, the bottom of the mixing barrel is fixedly connected to the top of the support plate three, and a feeding pipe is fixedly connected to the bottom of the mixing barrel.

[0010] As a further description of the above technical solution: the top of the mixing barrel is slidably connected to a barrel lid, and the top of the barrel lid is fixedly connected to a receiving pipe, and the feeding barrel and the receiving pipe are in the same vertical direction.

[0011] As a further description of the above technical solution: the inside of the bucket lid is rotatably connected to a rotating column, the top of the rotating column is fixedly connected to a disc, and the top of the disc is fixedly connected to a handle;

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the motor drives the drive column to rotate, which in turn drives the turntable to rotate.

At this time, the feeding hopper receives the material. When the feeding hopper rotates to the receiving pipe with the rotation of the turntable, the rotating block rotates with the inner groove of the rotating plate, and the feeding cover opens. At this time, the feeding hopper feeds the material to the mixing hopper through the receiving pipe, thereby achieving the effect of quantitatively adding calcium aluminate powder to ensure that the calcium aluminate powder reacts fully with hydrochloric acid.

[0016] 2. In this utility model, by rotating the handle, the disc is driven to rotate, which in turn drives the rotating column to rotate, causing the rotating rod to rotate around the rotating column, which in turn causes the rotating scraper to rotate on the inner wall of the mixing barrel, thereby effectively stirring the materials and scraping off the materials on the inner wall, improving the mixing effect.

[0030] Working principle:

[0031] The support plate 2 fixed inside the support frame 1 provides the mounting base for the motor 3. After the motor 3 starts, its drive end drives the drive column 4 to start rotating. The turntable 5, turntable 7, and feeding hopper 8 fixed outside the drive column 4 rotate synchronously. At the same time, the limiting ring 16 fixed on the top of the support plate 19 is rotatably connected to the drive column 4, providing stable support for the rotation of the drive column 4. The arc-shaped groove on one side of the limiting ring 16 plays a specific limiting role in subsequent work. Driven by the drive column 4, the feeding hopper 8 rotates to below the conveying pipe 18, and the conveyor 17 fixed on the top of the support frame 1 starts to work, conveying the liquid polyaluminum chloride raw material through the conveying pipe 18. At this time, the fixing block 9, fixing ring 10, fixing column 11, and other components fixed outside the feeding hopper 8 hold the feeding hopper 8 in place. As the feeding hopper 8 rotates to a specific position, the top of the rotating plate 14 slides at the bottom of the limiting ring 16. When the rotating plate 14 slides to the arc-shaped groove of the limiting ring 16, under the action of gravity or other mechanical structures, the rotating plate 14 drives the rotating block 13 and the rotating ring 12 to rotate around the fixed column 11, thereby opening the feeding cover 15 and allowing the material to fall smoothly into the feeding hopper 8. When the feeding hopper 8 continues to rotate away from the arc-shaped groove position, the feeding cover 15 closes again under the action of the corresponding structure, and the feeding hopper 8 continues to rotate. When it rotates to the top of the mixing hopper 22, since the feeding hopper 8 and the receiving pipe 24 are in the same vertical direction, the material in the feeding hopper 8 enters the mixing hopper 22 through the receiving pipe 24. The lid 23, which is slidably connected to the top of the mixing hopper 22, ensures that the material enters smoothly and prevents splashing.

[0032] Rotating handle 27 causes the disc 26 and rotating column 25 to rotate inside the lid 23. The clamping plate 35 fixed to the bottom of the rotating column 25 rotates accordingly, which in turn drives the rotating rod 29 to rotate. The rotating rod 29 is connected to the folding plate 31 via bolt 30, and the folding plate 31 is connected to the rotating scraper 33 via bolt 32. Therefore, the rotating scraper 33 rotates inside the mixing tank 22, thoroughly mixing the materials to achieve the mixing of liquid polyaluminum chloride. During the mixing process, the structure composed of the pressing column 36, limiting rod 37, spring 38, etc., ensures the clamping plate 35... 5. Stable connection with components such as rotating rod 29, while locking block 34 slides inside bolt 2 32 to ensure stable rotation of rotating scraper 33. After the batching is completed, liquid polyaluminum chloride has reached the required concentration and quality standard. The feed pipe 28 fixed at the bottom of batching tank 22 is in the state of waiting to be discharged. Open the valve on feed pipe 28, and liquid polyaluminum chloride is discharged from batching tank 22 through feed pipe 28 to enter subsequent packaging or other processing stages. Support plate 3 20 and support plate 4 21 provide stable support for batching tank 22 to ensure the smooth progress of the discharge process.
