Technical Field

[0001] This utility model relates to the field of centrifugal mother liquor technology, and in particular to a centrifugal mother liquor material recovery device. Background Technology

[0002] Centrifugal mother liquor is the liquid portion produced after centrifugation during chemical production, especially in the production of polyvinyl chloride (PVC). It contains unreacted monomers, dispersants, initiators, and other organic substances, as well as some inorganic salts and heavy metals, making it difficult to process.

[0003] In the existing technology, a centrifugal mother liquor material recovery device with application number CN202220947520.3 is proposed. In this application, the mother liquor settling and dissolving tank is also connected to the condenser through corresponding pipelines, which solves the environmental pollution problem of traditional filters in the recovery process, reduces and eliminates the strong odor and poor environment during on-site operation, and reduces labor costs. It eliminates the need for daily or 13 batches of mother liquor to be cleaned, thus saving labor costs. However, when heating the mother liquor, some materials are prone to remain, which affects the recovery of materials. At the same time, the recovery device needs to recover materials in batches by heating, which is not convenient for continuous and uninterrupted material recovery, resulting in low work efficiency.

[0040] Reference Figure 1-5 A centrifugal mother liquor recovery device includes a recovery tank 1, a recovery component 2, a storage component 3, a locking component 4, and a filtering component 5. The recovery component 2 is installed inside the rear end of the recovery tank 1 for recovering the centrifugal mother liquor. The storage component 3 is installed inside the front end of the recovery tank 1 for collecting materials in the mother liquor. The locking component 4 is installed at the front end of the recovery tank 1 for locking the components inside the storage component 3. The filtering component 5 is installed at the lower end of the recovery tank 1 for filtering the mother liquor.

[0041] Reference Figure 1-3 The recycling component 2 includes: a partition 201 fixedly installed at the top of the inside of the recycling bin 1; a lead screw 202 rotatably connected to the left and right sides of the inside of the recycling bin 1; a movable plate 203 rotatably connected to the outside of the lead screw 202; a hydraulic rod 204 fixedly installed inside the movable plate 203; a scraper 205 fixedly installed at the lower end of the hydraulic rod 204; and a filter plate 206 fixedly installed inside the recycling bin 1 at the lower end of the scraper 205. The storage component 3 includes: a storage box 301 slidably connected to the front end of the inside of the recycling bin 1; a support plate 302 fixedly installed at the lower end of the filter plate 206; a through groove 303 in the middle of the support plate 302; a guide platform 304 fixedly installed inside the recycling bin 1 at the lower end of the storage box 301; and a filter screen 305 provided at the lower end of the storage box 301.

[0042] In this invention, the recovery device is installed between the mother liquor feeding pump and the mother liquor treatment device. The centrifuged mother liquor is fed into the recovery tank 1. The partition 201 prevents the mother liquor from falling into the front end of the recovery tank 1, ensuring that most of the mother liquor is in contact with the filter plate 206. The filter plate 206 intercepts the solid materials in the mother liquor. Then, the motor is started to drive the lead screw 202 to rotate, thereby driving the movable plate 203 to slide. At the same time, the hydraulic rod 204 inside the movable plate 203 is activated. The hydraulic rod 204 drives the scraper 205 to press down and press against the filter plate 206. As the movable plate 203 slides to the front end, the scraper 205 scrapes the material intercepted on the filter plate 206, causing the material to fall into the collection component 3. The filter plate 206 is designed to facilitate preliminary filtration of the mother liquor, reducing the content of subsequent filtration materials. It also facilitates cleaning of the filter plate 206, preventing material accumulation on the filter plate 206 from affecting filtration efficiency. Solid materials scraped by the scraper 205 fall into the collection box 301 and onto the filter screen 305. Mother liquor adhering to the solid materials drips from the filter screen 305 onto the guide platform 304. The inclined design of the guide platform 304 allows the mother liquor to slide and contact the support plate 302, and enter the lower end of the filter plate 206 through the through groove 303 on the support plate 302. This facilitates the collection of materials in the mother liquor and reduces the amount of mother liquor adhering to the materials, thus reducing resource waste.

[0043] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The locking assembly 4 includes: a chute 401 at the front end of the recycling bin 1, a locking block 402 slidably connected inside the chute 401, a locking nut 403 threadedly connected to the front end of the locking block 402, and a pressure plate 404 rotatably connected to the rear end of the locking nut 403. The filter assembly 5 includes: a connecting pipe 501 fixedly installed at the lower end of the recycling bin 1, a filter tube 502 slidably connected to the lower end of the connecting pipe 501, a locking block 503 fixedly installed on the outside of the connecting pipe 501, a slot 504 opened at the upper end of the filter tube 502, a locking ring 505 rotatably connected to the outside of the connecting pipe 501 at the upper end of the locking block 503, and a bag filter 506 fixedly installed inside the filter tube 502.

[0044] In this invention, when the storage box 301 is removed, the locking nut 403 is loosened, thereby causing the pressure plate 404 to slide, disengaging the pressure plate 404 from its contact lock with the storage box 301. Then, the locking block 402 slides within the groove 401, disengaging the locking block 402 from the front end of the storage box 301, thus releasing the lock on the storage box 301. This facilitates the removal of the storage box 301 and the locking and unlocking of the storage box 301, ensuring the stability of the storage box 301 during use. When the mother liquor passes through the filter plate 2... After filtration, the mother liquor falls into the connecting pipe 501 and then into the filter tube 502, where it comes into contact with the bag filter 506, achieving secondary filtration of the mother liquor and further reducing the material content in the mother liquor, facilitating its subsequent utilization. At the same time, the locking block 503 on the connecting pipe 501 engages with the locking groove 504 on the filter tube 502, and the locking ring 505 is threadedly connected to the filter tube 502, facilitating the locking of the filter tube 502 and ensuring the tightness of the connection between the filter tube 502 and the connecting pipe 501.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
