Description

Technical Field

[0001] This utility model relates to the field of solid-liquid separation technology, and in particular to a solid-liquid separation device for the production of polyaluminum chloride. Background Technology

[0002] Polyaluminum chloride is an inorganic substance, a new type of water purification material, and an inorganic polymer coagulant, abbreviated as polyaluminum. During the production process of polyaluminum chloride, a certain amount of solid impurities are generated, which need to be separated into solid and liquid by centrifugal force.

[0003] By comparing a solid-liquid separation device for polyaluminum chloride production with patent publication number CN216726100U, in this scheme, the driving device drives the support cover and the filter screen fixed on the support cover to rotate. The centrifugal force generated by the driving device separates the solid and liquid. The separated liquid flows out from the drain pipe. However, the separated impurities will continue to exist inside the filter screen of the support cover. As more and more impurities are filtered out by the filter screen, although the spiral plate can scrape the impurities on the filter screen downwards, when the filter screen continues to rotate, these impurities will be continuously stuck to the side wall of the filter screen by the centrifugal force, which will continuously block the filter holes, thus affecting the solid-liquid separation efficiency of the mixture.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-6 As shown, a solid-liquid separation device for the production of polyaluminum chloride includes a separation tank 100 and a separation mechanism for separating the solution into solid and liquid components, which is located inside the separation tank 100.

[0028] In this embodiment: the separation mechanism includes a bottom filter plate 205 fixedly installed inside the separation tank 100. A liquid holding chamber 211 is provided between the bottom end of the bottom filter plate 205 and the separation tank 100. An inner cylinder 202 is provided at the upper end of the bottom filter plate 205. Multiple upper filter holes are provided around the outer wall of the inner cylinder 202. Multiple lower filter holes are provided around the surface of the bottom filter plate 205. A stirring structure for stirring the internal solution is provided on the inner wall of the separation tank 100. An anti-clogging structure for unblocking the blocked upper filter holes is provided on the side wall of the inner cylinder 202.

[0029] The anti-clogging structure includes multiple grooves 203 surrounding the outer wall of the inner cylinder 202. An inner push plate 204 is slidably installed in the grooves 203. The inner push plate 204 is made of rubber. The end of the inner push plate 204 away from the inner cylinder 202 is inclined in the counterclockwise direction of rotation. A compression spring is connected between the inner push plate 204 and the groove 203. Multiple upper filter holes on the outer wall of the inner cylinder 202 are distributed between two adjacent inner push plates 204. A rotary motor 201 is installed at the rotating end of the inner cylinder 202. The output end of the rotary motor 201 is fixed to the rotating end of the inner cylinder 202 through a coupling. The bottom end of the inner cylinder 202 is rotatably connected to the bottom filter plate 205. An adjustment structure is provided at the bottom end of the inner cylinder 202 for adjusting the extension length of the inner push plate 204.

[0030] The adjustment structure includes a fixed frame 206 fixedly installed at the bottom of the inner cylinder 202, a funnel 207 that slides up and down inside the fixed frame 206, a return spring connected between the funnel 207 and the fixed frame 206, a slider 208 fixed at the upper end of the funnel 207, the slider 208 being slidably connected to the inner cylinder 202, a guide roller 210 being rotatably installed at the center of the slide groove 203, and a pull rope 209 connected between the inner push plate 204 and the slider 208, the pull rope 209 being wound around the surface of the guide roller 210.

[0031] The stirring structure includes an outer cylinder 212 mounted on the inner wall of the separation tank 100. The bottom end of the outer cylinder 212 is rotatably connected to the bottom filter plate 205. Multiple push plates 213, made of rubber, are fixedly arranged around the inner wall of the outer cylinder 212. The push plates 213 are inclined in a clockwise or counterclockwise direction at the end near the inner cylinder 202. A large gear 214 is fixed at the top of the outer cylinder 212. A fixing plate is fixed on the outer wall of the separation tank 100 near the large gear 214. A small gear 215 is rotatably mounted on the upper end of the fixing plate. The small gear 215 meshes with the large gear 214. A drive motor 216 is mounted on the rotating end of the small gear 215. The output end of the drive motor 216 is connected via a coupling. The device is fixed to the rotating end of the pinion 215. The upper end of the separation tank 100 is provided with two feed pipes, and the rear end of the liquid holding tank 211 is fixed with a liquid outlet pipe. The mixture is separated into solid and liquid by the separation mechanism. Then, the anti-clogging structure drives the inner cylinder 202 to rotate. The centrifugal force generated when the inner cylinder 202 rotates throws the impurities attached to the side wall outward onto the bottom filter plate 205. At the same time, the more serious the blockage of the inner cylinder 202 by the impurities, the greater the centrifugal force generated by the inner cylinder 202, making it easier for the mixture to pass through the inner cylinder 202 to achieve solid-liquid separation. This improves the anti-clogging effect of the inner cylinder 202, improves the quality of solid-liquid separation of the mixture, and increases the efficiency of solid-liquid separation.

[0032] Working principle: First, a large amount of mixed liquid is poured into the separation tank 100. The impurities in the mixed liquid are separated by the inner cylinder 202 and the bottom filter plate 205. At the same time, the drive motor 216 drives the pinion 215 to rotate. The pinion 215 meshes with the large gear 214, which drives the large gear 214 to drive the outer cylinder 212 to rotate. This drives multiple outer push plates 213 to rotate. The rotation of the multiple outer push plates 213 stirs the mixed liquid, forming a downward vortex inside the mixed liquid. This further promotes the rapid downward flow of the mixed liquid through the inner cylinder 202. The liquid after solid-liquid separation flows through the funnel 207 at the bottom of the inner cylinder 202 and is collected in the liquid collection tank 211 below.

[0033] When multiple upper filter holes on the side wall of the inner cylinder 202 become clogged, the water flow rate through the funnel 207 will decrease, thus weakening the downward impact force on the funnel 207. As a result, the funnel 207 will move upward under the potential energy of the return spring. At this time, the drive motor 216 stops rotating the outer cylinder 212, and the rotary motor 201 starts rotating the inner cylinder 202. The rotation of the inner cylinder 202 generates centrifugal force, which throws the impurities adhering to the side wall of the inner cylinder 202 outward onto the bottom filter plate 205 below, reducing the amount of impurities adhering to the side wall of the inner cylinder 202 and reducing the clogging of the upper filter holes.

[0034] When the upward movement of funnel 207 increases, it indicates that the downward flow of water through funnel 207 is smaller, meaning less water flows into the inner cylinder 202. This leads to more severe blockage of the upper filter holes on the side wall of the inner cylinder 202. Furthermore, the greater the upward movement of funnel 207, the further the inner push plate 204 extends away from the center of the inner cylinder 202 under the influence of the compression spring's potential energy. This increases the distance between the end of the inner push plate 204 and the center of the inner cylinder 202, thereby increasing the centrifugal force generated when the inner cylinder 202 rotates. This increases the force that flings the impurities blocking the upper filter holes outwards, causing the blockage to detach from the side wall of the inner cylinder 202 more quickly. This ensures normal solid-liquid separation of the mixture by the inner cylinder 202 and reduces the likelihood of blockage in the upper filter holes of the inner cylinder 202.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
