Description

Technical Field

[0001] This utility model relates to the technical field of starch slurry dewatering equipment, and in particular to a rapid starch slurry dewatering machine. Background Technology

[0002] Starch slurry is a paste-like mixture formed during starch processing. Its high water content directly affects the efficiency of subsequent processing (such as drying and molding) and product quality. Therefore, dehydration is a crucial step in the starch slurry processing flow, and the starch slurry dewatering machine, as the key equipment for achieving this step, directly determines the dehydration efficiency, dehydration effect, and production energy consumption, occupying an irreplaceable position in the starch processing industry.

[0003] However, existing starch slurry dewatering machines have many shortcomings in practical applications. On the one hand, traditional dewatering machines mostly use a single dewatering method (such as relying solely on centrifugal filtration or vacuum filtration), resulting in low dewatering efficiency and insufficient dewatering, often leading to high moisture content in starch products. On the other hand, during centrifugal dewatering, solid substances in the starch slurry easily form filter cakes on the inner walls of filter components (such as filter cartridges). As the operating time increases, the continuous accumulation of filter cakes significantly reduces the filtration area, causing the dewatering rate to gradually decrease. This necessitates frequent shutdowns for cleaning, which not only affects production continuity but also increases labor costs and equipment wear and tear. Utility Model Content

[0013] 1. The starch slurry is initially and rapidly dehydrated by the centrifugal action of the filter cylinder in the dehydration mechanism. At the same time, the heating block in the conveying mechanism heats and dehumidifies in conjunction with the dehumidification component, further dehydrating the scraped starch. The dual dehydration method greatly improves the dehydration efficiency and effect. In addition, the turning plate on the outer periphery of the auger can turn the starch, making the heating and dehydration more uniform and thorough.

[0014] 2. The moving mechanism is driven by a servo motor to rotate the threaded rod, causing the conveying mechanism to move left and right as a whole. During this process, the scrapers on the left and right sides of the upper part of the receiving hopper move back and forth with the conveying mechanism, which can continuously scrape off the filter cake formed on the inner wall of the filter cylinder due to dehydration. This design can effectively avoid problems such as reduced filtration area and decreased dehydration rate caused by the accumulation of filter cake on the inner wall of the filter cylinder, ensuring that the filter cylinder always maintains a good filtration state, thereby significantly improving the efficiency of the overall dehydration operation.

A moving mechanism 4 is provided on the upper part of the fixed frame 2 3, and a conveying mechanism 5 is provided on the upper part of the moving mechanism 4.

[0024] In this embodiment, a feed pipe 6 is installed at the front of the conveying mechanism 5. A nozzle 7 is provided at one end of the feed pipe 6 near the fixed frame 1. The other end of the feed pipe 6 is connected to the starch slurry via a conveying pump. The nozzle 7 is located in the middle of the two scrapers 504 and faces the dewatering mechanism 2. The dewatering mechanism 2 includes a dewatering tank 201, rollers 202, an annular shaft 203, a filter cylinder 204, a reduction motor 205, and a drain outlet 206. The drain outlet 206 is located at the dewatering tank 201. At the lower part of the water tank 201, rollers 202 are installed on the left and right sides inside the dehydration tank 201. The rollers 202 are located on the outer periphery of the annular shaft 203, which is installed on the outer periphery of the filter cylinder 204. A geared motor 205 is installed on the right side of the dehydration tank 201. The output end of the geared motor 205 passes through the dehydration tank 201 and is fixedly connected to the middle of the filter cylinder 204. The conveying mechanism 5 includes a conveying component 501, a dehumidification component 502, a receiving hopper 503, and a scraper 504. The scraper 504 is installed in the receiving hopper.

The lower part of the left support base 401 is threadedly connected to the outer periphery of the threaded rod 405.

[0025] Specifically, the starch slurry is first pumped through the feed pipe 6 to the nozzle 7, which sprays the starch slurry onto the inner wall of the filter cylinder 204 of the dewatering mechanism 2. Then, the geared motor 205 drives the filter cylinder 204 to rotate. Under the action of centrifugal force, the water in the starch slurry passes through the filter cylinder 204 and is discharged from the drain port 206 at the bottom of the dewatering tank 201. The filter cake adheres to the inner wall of the filter cylinder 204, achieving preliminary dewatering. At the same time, the servo motor 404 of the moving mechanism 4 drives the threaded rod 405 to rotate, causing the support base 401 and the support rod 402 to move, which in turn drives the conveying mechanism 5 to move as a whole. The scraper 504 at the top of the receiving hopper 503 scrapes the starch adhering to the inner wall of the filter cylinder 204 into the receiving hopper 503.

[0026] In this embodiment, the conveying assembly 501 includes a conveying pipe 5011, a shaft 5012, an auger 5013, and a second geared motor 5014. The left end of the shaft 5012 is rotatably connected to the inner left side of the conveying pipe 5011, and the right end of the shaft 5012 penetrates the right side wall of the conveying pipe 5011 and extends into the receiving hopper 503. The middle part of the auger 5013 is located on the outer periphery of the shaft 5012. The second geared motor 5014 is installed on the outer left side of the conveying pipe 5011, and the right output end of the second geared motor 5014 penetrates the wall of the conveying pipe 5011 and is fixedly connected to the left end of the shaft 5012. The outer periphery of the auger 5013 is fixedly connected to multiple rotating parts at equal intervals. The material plate 5015 and the dehumidification assembly 502 include a dehumidification hood 5021, a dehumidification pipe 5022, a heat-conducting plate 5023, a heating block 5024, and a heat-insulating shell 5025. The lower part of the dehumidification hood 5021 is installed on the upper part of the conveying pipe 5011. One end of the dehumidification pipe 5022 is fixedly connected to the middle of the upper side of the dehumidification hood 5021. The heat-conducting plate 5023 is installed at the bottom of the conveying pipe 5011. Multiple geared motors 5014 are installed on the outer wall of the heat-conducting plate 5023. The heat-insulating shell 5025 is installed at the lower part of the conveying pipe 5011 and is located on the outer periphery of the heating block 5024. A temperature sensor is installed on the inner top wall of the dehumidification hood 5021.

[0027] Specifically, the starch in the receiving hopper 503 enters the conveying pipe 5011 of the conveying assembly 501. The geared motor 5014 drives the shaft 5012 and the auger 5013 on the outer periphery to rotate. The turning plate 5015 on the auger 5013 turns and conveys the starch. During this process, the heating block 5024 of the dehumidification assembly 502 heats the starch in the conveying pipe 5011 through the heat-conducting plate 5023, causing the moisture in the starch to evaporate. The moisture generated by evaporation is collected in the dehumidification hood 5021 and discharged through the dehumidification pipe 5022. The heat preservation shell 5025 reduces heat loss. The temperature sensor in the dehumidification hood 5021 monitors the temperature to regulate the heating state. Finally, the dehydrated starch is discharged from the end of the conveying pipe 5011 under the conveying of the auger 5013.

[0028] Working principle:

[0029] The starch slurry is first pumped through the feed pipe 6 to the nozzle 7, which sprays it onto the inner wall of the filter cylinder 204 of the dewatering mechanism 2. Then, the geared motor 205 drives the filter cylinder 204 to rotate. Under centrifugal force, the water in the starch slurry passes through the filter cylinder 204 and is discharged from the drain port 206 at the bottom of the dewatering tank 201. The filter cake adheres to the inner wall of the filter cylinder 204, achieving initial dewatering. Simultaneously, the servo motor 404 of the moving mechanism 4 drives the threaded rod 405 to rotate, causing the support base 401 and support rod 402 to move, which in turn moves the entire conveying mechanism 5. The scraper 504 at the top of the receiving hopper 503 scrapes the starch adhering to the inner wall of the filter cylinder 204 into the receiving hopper 503. Then… The starch in the receiving hopper 503 enters the conveying pipe 5011 of the conveying assembly 501. The geared motor 5014 drives the shaft 5012 and the auger 5013 on the outer periphery to rotate. The turning plate 5015 on the auger 5013 turns and conveys the starch. During this process, the heating block 5024 of the dehumidification assembly 502 heats the starch in the conveying pipe 5011 through the heat conduction plate 5023, causing the moisture in the starch to evaporate. The moisture generated by evaporation is collected in the dehumidification hood 5021 and discharged through the dehumidification pipe 5022. The heat preservation shell 5025 reduces heat loss. The temperature sensor in the dehumidification hood 5021 monitors the temperature to regulate the heating state. Finally, the dehydrated starch is discharged from the end of the conveying pipe 5011 under the conveying of the auger 5013.
