Description

Technical Field

[0001] This utility model relates to the field of polyaluminum chloride production technology, specifically to a storage device for polyaluminum chloride production. Background Technology

[0002] Polyaluminum chloride (PAC) exhibits high charge neutralization and bridging effects on colloids and particulate matter in water, and can powerfully remove toxic substances and heavy metal ions. It is stable and is widely used as an emerging water purification material and coagulant in the treatment of drinking water, industrial wastewater, and municipal sewage. PAC exists in both liquid and solid forms. Storage of liquid PAC is particularly important. A patent with publication number CN220032901U discloses a storage device for PAC production. During storage, an electric pusher drives a rotating ring. The rotating ring is connected to a lifting plate, allowing the lifting plate to rise and fall with the ring. As the lifting plate descends to the liquid surface, it compresses the air in its bottom space, increasing the air pressure. This pressure difference forces the air in the space to open the rubber cover, allowing the liquid to escape. The air enters the space at the top of the lifting plate, thereby moving the gas inside the tank to prevent contact between the gas and the polyaluminum chloride inside the tank. After entering the space at the top of the lifting plate, the air enters the exhaust ring, passes through the gas supply pipe, and finally enters the filter for filtration, reducing the accumulation of gas inside the tank. When the lifting plate is raised and lowered, it drives the scraper to move, scraping off the polyaluminum chloride on the inner wall of the storage tank, reducing the amount of polyaluminum chloride adhering to the storage tank and facilitating the discharge of polyaluminum chloride. However, although the discharge is convenient, the gas storage tank is not easy to rotate, making the loading inconvenient and the loading position relatively high. Therefore, a storage device for polyaluminum chloride production is designed to facilitate loading and unloading from a single inlet and outlet at the bottom, improving the convenience of loading and unloading, and also facilitating rotation to further increase the convenience of loading and unloading.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a storage device for the production of polyaluminum chloride, which has the following beneficial effects:

[0014] This storage equipment for polyaluminum chloride (PAC) production utilizes a combination of a sealing plug, a storage tank, and an elastic pressing mechanism. This allows for easy overcoming of the elastic pressing mechanism's downward pressure, enabling the pressurized inlet and outlet at the bottom to feed liquid PAC into the U-shaped frame. Simultaneously, the elastic pressing mechanism pushes the sealed plug towards the bottom of the storage tank, discharging the liquid PAC. The storage tank rotates on the U-shaped frame, facilitating easy loading and unloading, reducing the need to overcome the weight of the PAC during loading and improving ease of operation. Furthermore, the unloading angle can be easily adjusted during unloading, enhancing convenience. The equipment also allows for easy loading and unloading from a single bottom inlet and outlet, further facilitating the rotation process. Attached Figure Description

[0021] 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.

[0022] Example:

[0023] Please see Figure 1-5A storage device for the production of polyaluminum chloride includes a U-shaped frame 1 and a storage tank 2. The top of the storage tank 2 is rotatably connected to the U-shaped frame 1. The bottom of the storage tank 2 is provided with an inlet and an outlet. A valve 4 is installed at the bottom of the inlet and outlet. A sealing plug 3 is slidably fitted inside the storage tank 2. An elastic pressing mechanism is provided between the top of the storage tank 2 and the top of the sealing plug 3.

[0024] Specifically, the bottom of the storage tank 2 and the bottom of the sealing slide 3 are both set with an arc-shaped mechanism that seals and slides together. Setting the bottom of the storage tank 2 and the bottom of the sealing slide 3 with an arc-shaped mechanism makes it easy to lift the sealing slide 3 from the bottom, and at the same time makes it easy to discharge the liquid polyaluminum chloride downwards, further improving the convenience of loading and unloading.

[0025] Specifically, the elastic pressing mechanism includes a compression spring 13. A limiting plate 12 is fixedly installed on the top of the storage tank 2. The compression spring 13 is disposed between the limiting plate 12 and the sealing slide 3, and both ends of the compression spring 13 are fixedly connected to the limiting plate 12 and the compression spring 13 respectively. By setting the compression spring 13 and the limiting plate 12, it is convenient to maintain an up-down pressure on the sealing slide 3 at all times, and to make the compression spring 13 further compressed as the storage volume increases.

[0026] Specifically, the compression spring 13 has a built-in telescopic rod 14. The two ends of the telescopic rod 14 are fixedly connected to the limiting plate 12 and the sealing slide 3, respectively. The setting of the telescopic rod 14 increases the stability of the guide and limits the compression spring 13 to prevent the compression spring 13 from undergoing lateral deformation, thereby further ensuring the elastic pressing strength of the elastic pressing mechanism.

[0027] Specifically, it also includes a rotation adjustment mechanism for driving the storage tank 2 to rotate. The rotation adjustment mechanism includes a drive cylinder 8. A rotating plate 7 is rotatably connected to the U-shaped frame 1 on the side below the storage tank 2 via a rotating shaft 11. The drive cylinder 8 is fixedly installed on the rotating plate 7. The output shaft of the drive cylinder 8 is fixedly installed with a hinge seat 10. An L-shaped plate 9 is fixedly installed at the bottom of the storage tank 2 and rotatably connected to the hinge seat 10. Through the rotation adjustment mechanism, the tilt angle of the storage tank 2 can be easily rotated, thereby facilitating the adjustment of the inlet and outlet during loading and unloading. By extending or shortening the drive cylinder 8, the storage tank 2 can be easily driven to rotate through the cooperation of the hinge seat 10 and the L-shaped plate 9.

[0028] Specifically, the bottom of valve 4 is provided with a connecting pipe mechanism, which includes an external threaded pipe 5 that is fixedly connected to valve 4. An internal threaded movable sleeve 6 is threadedly connected to the external threaded pipe 5. Through the cooperation of the external threaded pipe 5 and the internal threaded movable sleeve 6, it is convenient to connect the external pipe to valve 4, thereby facilitating the pressurization and injection of liquid polyaluminum chloride into the inlet and outlet.
