DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0017] like Figure 1-Figure 8 As shown, a starch milk dehydration centrifuge for food processing provided by one embodiment of the present invention includes a frame 1 and further includes: The casing 2 comprises a shell 21 mounted on the frame 1, two bottom plates 25 are symmetrically arranged at the bottom of the shell 21, the two bottom plates 25 are hinged to the bottom of the shell 21, and an opening and closing unit 3 for driving the two bottom plates 25 to rotate is also arranged at the bottom of the frame 1, a top cover 22 is installed at the top of the shell 21, a feed port 23 is arranged at the upper part of the side wall of the shell 21, and a drain pipe 24 is arranged at the lower part of the side wall of the shell 21; The dehydration module 4 includes an outer cylinder 41 disposed inside the housing 21, a plurality of drainage holes 411 are provided on the side wall of the outer cylinder 41, a turntable 44 is installed on the top of the outer cylinder 41, a hollow shaft 441 is installed on the turntable 44, and a driving unit for driving the hollow shaft 441 to rotate is also provided on the top cover 22, a sealing plate 45 is provided at the bottom of the outer cylinder 41, a plurality of plug rods 46 are arranged in a circle on the sealing plate 45, and the plug rods 46 Slidingly installed in the outer cylinder 41 along the vertical direction, the inner cylinder 42 is installed inside the outer cylinder 41, the inner cylinder 42 includes a connecting cylinder 421 and a separation net cover 422, the connecting cylinder 421 is connected to the upper part of the outer cylinder 41 through a plurality of material delivery pipes 43, and each of the material delivery pipes 43 is distributed in a ring between the outer cylinder 41 and the connecting cylinder 421, the separation net cover 422 is plugged into the bottom of the connecting cylinder 421, and the bottom of the separation net cover 422 is connected to the bottom of the outer cylinder 41 through the connecting unit 7; The scraper module 6 is arranged inside the inner cylinder 42, and scrapes the starch on the inner wall of the separation mesh cover 422 onto the sealing plate 45 by reciprocating up and down motion. When the scraper module 6 moves to contact the sealing plate 45, the scraper module 6 will drive the connecting unit 7 to release the connection between the outer cylinder 41 and the separation mesh cover 422.

[0018] In the embodiment of the present invention, when in use, the two bottom plates 25 at the bottom are in a closed state, and the sealing plate 45 abuts against the bottom wall of the outer cylinder 41 and the separation mesh cover 422 to form a barrel-shaped container for holding starch milk. At this time, the connecting unit 7 connects the outer cylinder 41 with the separation mesh cover 422 so that the two keep synchronous movement. The starch milk is poured from the feed inlet 23 into the interior of the shell 21 through the feed inlet 23, and the starch milk can be transported to the barrel-shaped container through the feed pipe 43. Then the driving unit is started, and the hollow shaft 441 is driven to rotate by the driving unit. The hollow shaft 441 can drive the barrel-shaped container to rotate through the turntable 44. The centrifugal force generated by the rotation makes the starch adhere to the inner wall of the separation mesh cover 422, and the water is discharged from the drainage hole 411 opened on the outer cylinder 41, and finally discharged to the outside through the drainage pipe 24. After dehydration is completed, the scraping module 6 is controlled to scrape the starch attached to the inner wall of the separation mesh cover 422 onto the sealing plate 45. Then, the two bottom plates 25 are opened by the opening and closing unit 3, and the sealing plate 45 falls out, thereby taking out the dehydrated starch.

[0019] To clean or inspect the separation mesh cover 422, it is only necessary to control the scraper module 6 to move downward until it abuts against the sealing plate 45. At this time, the connecting unit 7 will disconnect the connection between the outer cylinder 41 and the separation mesh cover 422, and the separation mesh cover 422 will fall due to gravity, thereby conveniently removing the separation mesh cover 422.

[0020] In addition, it is necessary to additionally explain that, during the rotation of the outer cylinder 41, the feed pipe 43 will periodically align with the feed inlet 23. Therefore, intermittent feeding during the dehydration process can be automatically achieved, which can prevent the dehydration efficiency from being affected by excessive feeding at one time.

[0021] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the present invention, the opening and closing unit 3 includes two first hydraulic telescopic rods 31 symmetrically arranged on the frame 1, and the fixed ends of the two first hydraulic telescopic rods 31 are hinged to the frame 1, and the telescopic ends of the two first hydraulic telescopic rods 31 are hinged with hinge seats 32, and the two hinge seats 32 are respectively slidably installed on the bottom surfaces of the two base plates 25.

[0022] In the embodiment of the present invention, when in use, it is only necessary to control the two first hydraulic telescopic rods 31 to be extended and retracted synchronously. When the first hydraulic telescopic rod 31 is extended, the first hydraulic telescopic rod 31 can push the bottom plate 25 to rotate toward the side close to the bottom of the housing 21 through the hinge seat 32, so that the two bottom plates 25 are both attached to the bottom of the housing 21, thereby sealing the bottom of the housing 21. Conversely, when the first hydraulic telescopic rod 31 is retracted, the two bottom plates 25 can be driven to rotate toward the side away from the bottom of the housing 21 through the hinge seat 32, so that the separated starch or related components can be taken out from the bottom of the housing 21.

[0023] like Figure 2 As shown, as a preferred embodiment of the present invention, the driving unit includes a driving motor 47 installed on the top cover 22, and the output end of the driving motor 47 is connected to the hollow shaft 441 through a transmission member.

[0024] In the embodiment of the present invention, the transmission member is a pulley belt mechanism. When in use, it is only necessary to start the driving motor 47, and the driving motor 47 can drive the hollow shaft 441 to rotate through the pulley belt mechanism, thereby driving the rotating disk 44 to rotate synchronously through the hollow shaft 441.

[0025] like Figure 1 , Figure 3 and Figure 6 As shown, as a preferred embodiment of the present invention, the scraper module 6 includes an annular scraper 63 installed inside the inner cylinder 42, and a second hydraulic telescopic rod 61 installed on the top of the top cover 22, the outer diameter of the annular scraper 63 is the same as the inner diameter of the separation mesh cover 422, and a connecting column 62 is connected to the middle part of the annular scraper 63, and the connecting column 62 passes through the center of the hollow rotating shaft 441 and is connected to the telescopic end of the second hydraulic telescopic rod 61.

[0026] In the embodiment of the present invention, when in use, in the initial state, the annular scraper 63 is at the upper limit position, and the lowest end of the annular scraper 63 is located above the feed pipe 43. When the starch inside the separation mesh cover 422 is to be scraped off, it is only necessary to control the second hydraulic telescopic rod 61 to extend, and the second hydraulic telescopic rod 61 can drive the annular scraper 63 to move downward through the connecting column 62, and the starch attached to the inner wall of the separation mesh cover 422 is scraped off by the annular scraper 63, so that it falls on the sealing plate 45. When the annular scraper 63 moves to the lower edge of the separation mesh cover 422, the second hydraulic telescopic rod 61 contracts, thereby driving the annular scraper 63 to move upward, and the starch attached to the inner wall of the separation mesh cover 422 is removed by reciprocating scraping.

[0027] like Figure 6 , Figure 7 and Figure 8 As shown, as a preferred embodiment of the present invention, the connecting unit 7 is provided with multiple groups, and each group of the connecting units 7 is distributed in a ring between the outer cylinder 41 and the separation mesh cover 422, the connecting unit 7 includes a first plug-in block 71 installed at the bottom of the outer cylinder 41, and a mounting seat 73 arranged at the bottom of the separation mesh cover 422, a mounting groove 731 is opened in the mounting seat 73, a second plug-in block 74 is installed in the mounting groove 731, and a ramp 741 is arranged at one end of the second plug-in block 74 close to the center of the separation mesh cover 422, the first plug-in block 71 and the second plug-in block 74 can both slide along the radial direction of the sealing plate 45, the first plug-in block 71 is connected to the outer cylinder 41 through the first spring 72, the second plug-in block 74 is connected to the inside of the mounting groove 731 through the second spring 75, and when not subjected to external force, the first plug-in block 71 will be inserted into the mounting groove 731 and abut against the second plug-in block 74, and the ramp 741 will be ejected from the mounting groove 731.

[0028] In the embodiment of the present invention, specifically, the first spring 72 is a tension spring, and the second spring 75 is a compression spring. When in use, under normal conditions (i.e., when not subject to external force), the first plug block 71 will be inserted into the mounting groove 731 and abut against the second plug block 74, and the ramp 741 will be pushed out from the mounting groove 731. At this time, the separation mesh cover 422 is fixed on the outer cylinder 41, and the separation mesh cover 422 will not fall off even after the sealing plate 45 is removed. When the separation mesh cover 422 is to be replaced or overhauled, it is only necessary to control the annular scraper 63 to continue to move downward for a distance after reaching the lower edge of the separation mesh cover 422, so that the annular scraper 63 abuts against and squeezes the ramp 741, so that the second plug block 74 is retracted into the mounting groove 731 as a whole. At the same time, the first plug block 71 will be pushed by the second plug block 74 and withdraw from the mounting seat 73. After the sealing plate 45 is removed, the separation mesh cover 422 can be easily removed from the outer cylinder 41 under the action of gravity, so as to facilitate inspection and cleaning.

[0029] like Figure 7 and Figure 8 As shown, as a preferred embodiment of the present invention, the thickness of the mounting seat 73 is greater than the thickness of the separation mesh cover 422, and a step is formed on the side facing the inner wall of the outer cylinder 41, and the top outer side of the step is chamfered.

[0030] In the embodiment of the present invention, it is necessary to additionally explain that when the first plug block 71 is not subjected to external force, the depth of the first plug block 71 inserted into the mounting seat 73 does not exceed the outer wall of the separation net cover 422. Through such a setting, it can be ensured that the first plug block 71 will not interfere with the installation during the process of reinstalling the separation net cover 422 to the outer cylinder 41. When the top of the step contacts the first plug block 71, the first plug block 71 can be pushed outward through the inclined surface at the bevel, and finally the first plug block 71 is inserted into the mounting seat 73 again.

[0031] like Figure 5-Figure 8 As shown, as a preferred embodiment of the present invention, a plurality of groups of vibration units 5 for reciprocatingly knocking the separation net cover 422 are arranged in a circle on the inner wall of the outer cylinder 41, and the number of the vibration units 5 is the same as the number of the insertion rods 46. The vibration unit 5 includes a vibration rod 51 and a protrusion 52, and a plurality of the vibration rods 51 are evenly distributed along the length direction of the insertion rod 46, each of the vibration rods 51 is rotatably mounted on the inner wall of the outer cylinder 41, and a reset torsion spring is arranged at the connection between each of the vibration rods 51 and the outer cylinder 41, and a plurality of protrusions 52 are evenly arranged along the length direction of the insertion rod 46 on one side close to the separation net cover 422.

[0032] In the embodiment of the present invention, the two ends of the vibration rod 51 are respectively abutted against the insertion rod 46 and the separation mesh cover 422 by the reset torsion spring. When the sealing plate 45 is installed in place, one end of the vibration rod 51 abuts against the inner wall of the insertion rod 46. In the process of removing the sealing plate 45, the insertion rod 46 will move downward synchronously, so that the protrusions 52 provided thereon will contact with each vibration rod 51 correspondingly. The protrusions 52 will cause the vibration rod 51 to rotate, so that the end of the vibration rod 51 will no longer abut against the outer wall of the separation mesh cover 422. When the protrusions 52 are separated from the vibration rod 51, the vibration rod 51 will be affected by the elastic restoring force of the reset torsion spring and abut against the inner wall of the separation mesh cover 422 again, and the separation mesh cover 422 will be knocked once in the process. Through multiple knocks, the tightness of the starch attached to the separation mesh cover 422 can be reduced, and the starch that cannot be scraped off can be shaken off from the separation mesh cover 422.

[0033] Working principle: When in use, the two bottom plates 25 are in a closed state, and the sealing plate 45 abuts against the bottom wall of the outer cylinder 41 and the separation mesh cover 422 to form a barrel-shaped container for holding starch milk. At this time, the connecting unit 7 connects the outer cylinder 41 with the separation mesh cover 422 so that the two keep moving synchronously. The starch milk is poured from the feed port 23 into the interior of the outer shell 21, and the starch milk can be transported to the barrel-shaped container through the feed pipe 43. Then the driving unit is started, and the hollow shaft 441 is driven to rotate by the driving unit. The hollow shaft 441 can drive the barrel-shaped container to rotate through the turntable 44. The centrifugal force generated by the rotation makes the starch adhere to the inner wall of the separation mesh cover 422, and the water is discharged from the drainage hole 411 opened on the outer cylinder 41, and finally discharged to the outside through the drainage pipe 24. After dehydration is completed, the second hydraulic telescopic rod 61 is controlled to extend, and the second hydraulic telescopic rod 61 can drive the annular scraper 63 to move downward through the connecting column 62, and the starch attached to the inner wall of the separation net cover 422 is scraped off by the annular scraper 63, so that it falls on the sealing plate 45. When the annular scraper 63 moves to the lower edge of the separation net cover 422, the second hydraulic telescopic rod 61 contracts, thereby driving the annular scraper 63 to move upward, and through reciprocating scraping, the starch attached to the inner wall of the separation net cover 422 is scraped off onto the sealing plate 45. Then, the two bottom plates 25 at the bottom are opened by the opening and closing unit 3, and the sealing plate 45 will fall out, so that the dehydrated starch can be taken out. In the process of the sealing plate 45 falling, the insertion rod 46 will move downward synchronously, so that the protrusions 52 provided thereon will contact the corresponding vibration rods 51, and the protrusions 52 will cause the vibration rods 51 to rotate, so that the ends of the vibration rods 51 will no longer abut against the outer wall of the separation mesh cover 422. When the protrusions 52 are separated from the vibration rods 51, the vibration rods 51 will be affected by the elastic restoring force of the reset torsion spring and abut against the inner wall of the separation mesh cover 422 again, and in this process, the separation mesh cover 422 will be knocked once. Through multiple knocks, the starch that cannot be scraped off will be shaken off the separation mesh cover 422.

[0034] If the separation net cover 422 is to be cleaned or repaired, the annular scraper 63 is controlled to continue to move downward for a distance after reaching the lower edge of the separation net cover 422, so that the annular scraper 63 abuts against and squeezes the inclined platform 741, so that the second plug block 74 is completely retracted into the installation groove 731. At the same time, the first plug block 71 is pushed by the second plug block 74 and withdraws from the installation seat 73. Under the action of gravity, the separation net cover 422 can be easily taken out from the inside of the outer cylinder 41, which is convenient for inspection and cleaning.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
