Description

Technical Field

[0001] This utility model relates to the field of deep processing of starch products, and in particular to a waste recycling device for deep processing of starch products. Background Technology

[0002] In the field of deep processing of starch products, the waste generated contains a large amount of bound water (free water accounts for >80%). During the processing, the moisture is difficult to evaporate naturally due to starch gelatinization and protein precipitation. The presence of oil and salt in the waste will form a colloidal protective layer, which hinders the migration of moisture and has strong hygroscopicity. When the waste is piled up, the particles stick together due to capillary action. High-salt environments (such as pickling waste) accelerate the formation of ionic bonds and aggravate agglomeration and hardening.

[0003] Existing equipment has a single function during use, requires the combination of multiple devices for processing, and causes spillage during waste movement, making it difficult to recycle and resulting in low processing efficiency. Therefore, we have proposed a waste recycling device for deep processing of starch products to solve the problems mentioned above. Utility Model Content

[0004] In order to overcome the problems of low processing efficiency and waste spillage in existing waste recycling devices for deep processing of starch products.

[0005] The technical solution of this utility model is: a waste recycling device for deep processing of starch products, including a filtration and conveying component, an ultrafiltration component, a blower component, a processing module, and a control component; the filtration and conveying component is provided as the core conveying unit, and several sets of blower components are linearly integrated on the filtration and conveying component for directional airflow to quickly dry the residual liquid on the surface of the waste. The filtration and conveying component is connected to an ultrafiltration component for separating the waste liquid after primary filtration. The processing module is connected below the filtration and conveying component, away from the ultrafiltration component, and works with the blower component to complete the final dehydration and forming operation of the waste. The processing module housing is integrated with a control component for operation and adjustment, realizing real-time monitoring and automatic adjustment of equipment operating parameters.

[0006] Preferably, the filter conveying assembly includes a square hopper, with a conveying impeller for primary diversion on the lower side of the square hopper, which initially separates solid-liquid mixed waste materials, achieves dynamic sealing connection, and avoids waste leakage. A battery-driven motor is provided on the coaxial side of the conveying impeller, and the output shaft of the battery-driven motor is rigidly connected to the conveying impeller on the same coaxial side. Two sets of rollers for lateral transmission are provided below the conveying impeller.

[0007] Preferably, a transverse polymer fiber filter cloth conveyor belt is fitted on the outer side of the two sets of rotating rollers. The surface of the conveyor belt is coated with a hydrophobic coating to improve the solid-liquid separation efficiency. The two sets of rotating rollers are coaxially connected to a first drive motor. The first drive motor drives the two sets of rotating rollers to rotate the drive belt. An adjustable polyurethane scraper is provided on the rotating rollers away from the first drive motor. The cutting edge of the polyurethane scraper is parabolic to achieve efficient removal of residual solids on the surface of the filter cloth. The polyurethane scraper assembly adopts a magnetic quick-release interface for easy maintenance and cleaning.

[0008] Preferably, the blower assembly includes a support ring with several sets of threaded holes circumferentially distributed near its edge. A support column, corresponding to the threaded holes, is fixed to the outer wall of the filter conveying assembly on the lower side of the support ring. The support column and the threaded holes of the support ring are fixed together by bolts, enabling modular disassembly of the blower assembly and supporting independent maintenance and replacement of individual blower assemblies. A permanent magnet synchronous motor is fixed to the middle of the support ring, and an aluminum alloy centrifugal impeller is located below the support ring. A flange coupling for transmitting axial power is provided between the permanent magnet synchronous motor and the aluminum alloy centrifugal impeller. A MEMS micro-differential pressure sensor is embedded inside the aluminum alloy centrifugal impeller to monitor the pressure gradient changes at the inlet and outlet ends in real time.

[0009] Preferably, the upper part of the processing module housing is a collection area, which is equipped with a gear shaft assembly that rotates and meshes with each other. A second drive motor is set on the outside of the gear shaft assembly and is coaxially connected to the gear shaft through a coupling. The second drive motor drives the gear shaft assembly to achieve meshing transmission, realizing the primary crushing and pre-compression of waste materials. A horizontal grinding roller is installed at the bottom of the collection area. A variable frequency motor is fixed to the outer wall of the processing module housing on the outside of the horizontal grinding roller shaft. The output shaft of the variable frequency motor is rigidly connected to the grinding roller shaft on the same axis. The horizontal arrangement of the horizontal grinding roller can improve the material grinding efficiency, and the axial direct connection design can effectively reduce transmission loss.

[0010] Preferably, the lower part of the processing module box is a vibration zone, and an inclined microporous screen is provided inside the vibration zone. Several sets of transversely distributed vibrating rods are fixed to the lower screen surface of the inclined microporous screen. A spiral extrusion screw is provided on the lower exterior of the processing module box. Corresponding vibrating blocks are provided at the bottom of the vibrating rods and above the spiral extrusion screw. A vibration controller is provided inside the vibrating blocks. The vibration of the vibrating rods prevents the particles on the microporous screen from accumulating. A drive servo motor is provided at one end of the spiral extrusion screw. The servo motor drives the screw to reciprocate to collect waste materials.

[0011] Preferably, the ultrafiltration module has three sets of membranes stacked from bottom to top inside. The three sets of membranes include a polypropylene microporous pretreatment membrane, a main separation membrane, and a PVDF fine filtration membrane. The three sets of membranes form a hierarchical filtration system to ensure the final removal of small molecule impurities. A flow guiding cavity is provided around the three sets of membranes. The flow guiding cavity is sealed and interconnected with the membrane system at the bottom. The flow guiding cavity is connected to the flow guiding pipe in the middle of the treatment module box.

[0012] The beneficial effects of this utility model are:

[0013] The filtration and conveying assembly achieves initial solid-liquid separation of waste materials without leakage. The blower assembly rapidly dries residual liquid on the waste surface, further reducing its moisture content. The conveyor belt surface and dehydration chamber surface are coated with a composite hydrophobic coating, which, combined with the scraper self-cleaning mechanism, continuously demolds the waste material, reducing its adhesion. The subsequent processing module forms a continuous processing technology of graded crushing, precision grinding, vibrating screening, and extrusion molding, enabling the collection of solid residue from the waste material, which can be used as animal feed, reducing resource waste. The three-stage membrane stacking structure further intercepts and treats the filtrate with larger particle sizes. The integrated control system enables real-time monitoring and automated adjustment of equipment operating parameters, making it more efficient and convenient. Attached Figure Description

[0021] Please see Figure 3-4In this embodiment, the blower assembly 3 includes a support ring 305. Several sets of threaded holes are circumferentially distributed on the support ring 305 near its edge. A support column 304, corresponding to the threaded holes, is fixed to the outer wall of the filter conveying assembly 1 on the lower side of the support ring 305. The support column 304 and the threaded holes of the support ring 305 are threadedly fixed by bolts 306. A permanent magnet synchronous motor 301 is fixed to the middle of the support ring 305. An aluminum alloy centrifugal impeller 302 is located below the support ring 305. A flange coupling 303 for transmitting axial power is provided between the permanent magnet synchronous motor 301 and the aluminum alloy centrifugal impeller 302. A MEMS micro-differential pressure sensor is embedded inside the aluminum alloy centrifugal impeller 302. The upper part of the processing module 4 housing is a collection area, within which a gear shaft assembly 401 is installed, rotating and meshing with each other. A second drive motor 410, located on the outer side of the gear shaft assembly 401, is coaxially connected to the gear shafts via a coupling. The second drive motor 410 drives the gear shaft assembly 401 to achieve meshing transmission. A horizontal grinding roller 402 is horizontally installed at the bottom of the collection area. A variable frequency motor 403, rigidly connected to the outer wall of the processing module 4 housing, is located on the outer side of the horizontal grinding roller 402 shaft. The output shaft of the variable frequency motor 403 is rigidly connected to the horizontal grinding roller 402 shaft, coaxially. The lower part of the processing module 4 housing is a vibration zone, within which an inclined microporous sieve 404 is installed. The lower sieve surface of the inclined microporous sieve 404 is fixed. Several sets of transversely distributed vibrating rods 406 are connected to the processing module 4.

The filtrate after ultrafiltration is output through the flow guide pipe 205. The purified permeate water can be reused for the deep processing of starch products.

[0022] During operation, waste enters the square hopper 103 and is fed into the conveyor belt 102 by the conveyor impeller 101 for preliminary filtration and dehydration. Then, it is driven by the conveyor belt 102 into multiple sets of blower components 3 to efficiently dehydrate the surface moisture of the waste. At the end of the conveyor belt 102, the polyurethane scraper 104 peels off the waste adhering to the surface of the conveyor belt 102. The dried waste enters the collection area and is initially crushed by the gear shaft assembly 401. Then, it enters the fixed-size horizontal grinding roller 402 for extrusion and crushing. The crushed waste is sieved and extruded into shape under the action of the screw extrusion screw 407. The formed filter residue can be used as animal feed. The filtrate after preliminary filtration is further treated by the ultrafiltration component 2 to remove dissolved small molecule impurities. The treated filtrate can be reused in the deep processing of starch products. The control component 5 realizes real-time monitoring of the entire process.

[0023] The above steps improve the efficiency of waste recycling and make the integrated control system more convenient to operate.
