Description

Technical Field

[0001] This utility model belongs to the field of polyaluminum chloride production, and in particular relates to a filter residue screening device for polyaluminum chloride production. Background Technology

[0002] Polyaluminum chloride (PAC) is an important inorganic polymeric flocculant widely used in water treatment. It neutralizes the surface charge of colloidal particles in water, causing them to aggregate into larger flocs, facilitating sedimentation or filtration. Compared to traditional aluminum salts, PAC offers advantages such as superior flocculation, lower dosage, and greater adaptability. In practical applications, PAC is widely used in tap water purification, industrial wastewater treatment, paper sizing, and pharmaceutical refining. With increasing environmental protection requirements, efficient, low-consumption, and safe PAC is gradually replacing traditional coagulants, becoming one of the core materials in modern water treatment. Screening the filter residue generated during PAC production is a crucial step in ensuring product quality and resource recycling. Optimizing screening and recovery not only reduces raw material consumption but also decreases the amount of filter residue generated per ton of product, significantly improving the economic and environmental benefits of the production line.

[0003] Comparing with Chinese Patent CN219965537U, a screening device for filter residue in the production of polyaluminum chloride is disclosed. The device includes a main body with a screening chamber inside. A screening mechanism is installed within the screening chamber, and a discharge pipe penetrating the main body is fixedly installed at the bottom of the screening chamber. A gas filtration mechanism is fixedly installed on the side wall of the main body. Through the cooperation of a first screening frame and a second screening frame within the screening mechanism, the polyaluminum chloride filter residue is thoroughly screened. The first and second screening frames are connected by a connecting component, which enhances the vibration effect of the second screening frame, thereby improving the screening effect of the polyaluminum chloride filter residue. During the screening process, the gas filtration mechanism on the side wall of the main body filters out harmful gases generated during screening, reducing harmful substances in the gas and minimizing the impact on the surrounding environment after gas discharge.

[0004] However, the aforementioned patent cannot continuously screen the filter residue and raw materials, requiring periodic shutdowns to clean the filter residue, which reduces production efficiency, easily causes blockages, and increases labor intensity. Therefore, a new type of equipment needs to be designed. Utility Model Content

[0026] Please see Figures 1-6 A screening device for filter residue in the production of polyaluminum chloride includes a frame assembly for supporting the feeding, and a separation component for continuously oscillating and screening the filter residue, which is installed at an incline in the middle of the frame assembly. One end of the separation component is provided with a drive component for providing oscillation power.

[0027] In this embodiment: the frame assembly includes a base plate 101, on which four support columns 102 are evenly distributed. One end of the base plate 101 is provided with a feeding mechanism for fixing the raw materials, and the other end of the base plate 101 away from the feeding mechanism is provided with a partition plate 103. The feeding mechanism includes a fixed frame 104, and a fixed hopper 105 is fixedly provided at the top of the fixed frame 104. The fixed hopper 105 is conical and located at the center directly above the moving area of ​​the movable hopper 202. Raw materials are continuously poured from the fixed hopper 105 supported by the fixed frame 104. Gravity causes the raw materials to fall into the movable hopper 202 under the guidance of the fixed hopper 105. The support column 102 at one end of the base plate 101 supports a fixed rotary motor 305 to drive the support shaft 302 to rotate, and the support column 102 at the other end of the base plate 101 supports the movable rotating shaft 205 to rotate. The partition plate 103 on the base plate 101 separates the screened raw materials and filter residue to prevent re-mixing.

[0028] In this embodiment: the separation component includes a box mechanism for sealing and screening filter residue. A movable hopper 202, which is frustoconical in shape, is located at the top of one end of the box mechanism. A screening screen 207 is installed at an incline in the middle of the box mechanism. Two discharge pipes 206 are evenly distributed at the bottom of the end of the box mechanism away from the movable hopper 202. The box mechanism includes a screening box 201. Two movable rotating shafts 205 are symmetrically arranged on both sides of the screening box 201 near the movable hopper 202. Two fixed rotating shafts 204 are symmetrically arranged on both sides of the end of the screening box 201 away from the movable hopper 202. A partition plate 208 is provided inside the end of the screening box 201 away from the movable hopper 202. The screening screen 207 is fixedly installed at the top of the partition plate 208. The two discharge pipes 206 are respectively located on both sides of the partition plate 208. A maintenance cover 203 is installed on one end face of the movable hopper 202, and the maintenance cover 203 is snapped to the screening box 201. The raw material passes through the movable hopper 202 and falls onto the screening screen plate 207 of the screening box 201. The movable shaft 205 drives one end of the screening box 201 to move, so that the screening box 201 swings under the support of the fixed shaft 204 at the other end. The screening screen plate 207 supported by the partition plate 208 also shakes, so that the raw material passes through the screening screen plate 207 and falls into the bottom of the screening box 201, and flows along the bottom of the screening box 201 and is discharged from the discharge pipe 206 on one side of the partition plate 208. The filter residue is filtered and blocked by the screening screen plate 207 and flows along the screening screen plate 207 to the discharge pipe 206 on the other side of the partition plate 208 and is discharged. After screening is completed, the maintenance cover 203 is opened to clean and maintain the screening screen plate 207.

[0029] In this embodiment: the drive assembly includes two symmetrically arranged support shafts 302, with a rotating disk 301 at opposite ends of the support shafts 302. A rotary motor 305 is installed at the outer end of one of the support shafts 302.

The rotating disk 301 is disc-shaped with a diameter of 20 cm. The rotary motor 305 drives the support shafts 302 to rotate the rotating disk 301. The rotating disk 301 drives the movable connecting plate 303 to move through the eccentric shaft 304. The movable connecting plate 303 then drives one end of the screening box 201 to move through the movable rotating shaft 205.

[0030] Working principle: Raw materials are continuously poured into the fixed hopper 105 supported by the fixed frame 104. Gravity guides the raw materials from the fixed hopper 105 into the movable hopper 202, and then through the movable hopper 202 onto the screening screen plate 207 of the screening box 201. The bottom plate 101 supports the rotary motor 305 via the support column 102, which drives the support shaft 302 to rotate the rotating disk 301. The rotating disk 301 drives the movable connecting plate 303 to move via the eccentric shaft 304. The movable connecting plate 303 then drives one end of the screening box 201 to move via the movable rotating shaft 205, so that the screening box 201 is fixed at the other end. Supported by 04, the screen plate 207 supported by the partition plate 208 also sways, causing the raw material to pass through the screen plate 207 and fall into the bottom of the screening box 201. It then flows along the bottom of the screening box 201 and is discharged from the discharge pipe 206 on one side of the partition plate 208.
