Description

Technical Field

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

[0002] Polyaluminum chloride (PAC) is classified into two types: one for drinking water and one for industrial water, each adhering to different relevant standards. It appears in yellow, light yellow, dark brown, or dark gray colors and exists in both liquid and solid forms. During production, it requires drying. A search revealed that patent CN222364318U discloses a special drum drying device for PAC production, including a base and a drying mechanism for the PAC production process. One side of the bottom of the drying mechanism is equipped with a support component for supporting and rotating the mechanism, while the other side is equipped with a drive component for driving the drying mechanism. This invention first feeds the polyaluminum chloride (PAC) to be dried into the drying drum through the inlet and outlet, then seals the inlet and outlet with a servo motor. The drying drum then rotates, allowing for the continuous drying of the PAC. After drying, the second connecting lug is moved upwards by an electric cylinder, lifting one side of the drying rack and allowing the PAC inside to be poured out to the inlet and outlet. This facilitates convenient and thorough discharge of the PAC, improving its practicality. However, during unloading, the center of gravity shifts, resulting in poor stability. To ensure complete unloading, the entire drum may tip over. Furthermore, raising one side of the drying drum increases energy consumption. Therefore, this invention designs a rotary drum drying device for PAC production that prevents the center of gravity from shifting during unloading, improves stability, and reduces energy consumption.

[0014] This rotary drum dryer for polyaluminum chloride production, through the cooperation of a stirring mechanism and a stirring drive mechanism, facilitates the stirring of materials entering the drum through the material inlet and outlet, accelerating the drying process within the drum.

[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. Example

[0022] Please see Figure 1-5 A drum drying device for producing polyaluminum chloride includes a support frame 1, a drum 2 with a circumferentially oriented material inlet and outlet 4 connected to the support frame 1 in a rotatable manner, a stirring mechanism inside the drum 2, a stirring drive mechanism for driving the stirring mechanism to rotate and a flipping drive mechanism for driving the drum 2 to rotate on the support frame 1, and a positioning mechanism for positioning the drum 2 in the orientation state of the material inlet and outlet 4.

[0023] Specifically, both ends of the drum 2 are fixedly installed with sleeves 3 that are rotatably connected to the support frame 1. The stirring mechanism includes a stirring shaft 10 that is sealed and rotatably passes through the two sleeves 3. Multiple stirring blades 11 are fixedly installed on the stirring shaft 10 at a position inside the drum 2. The stirring drive mechanism is used to drive the stirring shaft 10 to rotate. Activating the stirring drive mechanism facilitates the rotation of the stirring shaft 10, which in turn drives the multiple stirring blades 11 to rotate, thereby stirring the material inside the drum 2, accelerating the contact between the material and the inner wall of the drum 2, and improving its drying efficiency.

[0024] Specifically, the flipping drive mechanism includes a flipping motor 15 fixedly mounted on the support frame 1. A main gear 14 and a driven gear 13 are fixedly mounted on the output shaft of the flipping motor 15 and one of the sleeves 3, respectively. The main gear 14 and the driven gear 13 mesh with each other. When the flipping motor 15 is started, the output shaft of the flipping motor 15 rotates clockwise or counterclockwise, thereby driving the main gear 14 to rotate clockwise or counterclockwise, thereby driving the driven gear 13, the sleeve 3, and the roller 2 as a whole to rotate counterclockwise or clockwise.

[0025] Specifically, the stirring drive mechanism includes a stirring motor 12 fixedly mounted on the support frame 1. The output shaft of the stirring motor 12 is fixedly connected to one end of the stirring shaft 10. The stirring motor 12 and the tilting motor 15 are located on the same side of the support frame 1. When the stirring motor 12 is started, the output shaft of the stirring motor 12 rotates, thereby driving the stirring shaft 10 to rotate.

[0026] Specifically, the positioning mechanism includes a lifting drive cylinder 6 fixedly installed on the support frame 1. A lifting plate 7 is fixedly installed on the top output shaft of the lifting drive cylinder 6. Both sides of the top of the lifting plate 7 are fixedly installed with locking blocks 8 that engage with the sleeve 3. The lifting drive cylinder 6 facilitates the overall lifting and lowering of the lifting plate 7 and the two locking blocks 8. When the locking blocks 8 are disengaged from the sleeve 3, the lifting plate 7 can be released from its restriction on the sleeve 3. When the locking blocks 8 are engaged with the sleeve 3, the sleeve 3 can be positioned to prevent the roller 2 from rotating. Furthermore, both sides of the support frame 1 are provided with guide grooves 9 that slide vertically with the lifting plate 7, which facilitates the vertical guidance of the lifting plate 7 and the two locking blocks 8 as a whole, increasing the vertical stability of the positioning mechanism.

[0027] Specifically, a hopper 5 is fixedly installed on the top of the support frame 1, which is directly above the roller 2. The bottom opening of the hopper 5 is smaller than the specification of the material inlet / outlet 4, so that materials can be easily added to the material inlet / outlet 4 through the hopper 5.
