Description

Technical Field

[0001] This utility model relates to the field of sugar powder sieving technology, and in particular to a sugar powder sieving device. Background Technology

[0002] During the sugar powder production process, the sugar powder has different particle sizes after crystallization, crushing, and drying, thus requiring screening to ensure its quality. Currently, sugar powder is usually screened using a screening device. The screening device has a filter screen inside. The sugar powder is poured into the screening device and screened through the screen. Smaller sugar powder particles pass through the screen, while larger sugar powder particles are retained on the screen, thus completing the screening process.

[0003] However, in existing technologies, the sugar powder to be sieved is usually put into the sieving device all at once. A large amount of sugar powder falls onto the screen, and the sugar powder tends to clump together and form local accumulations, resulting in slow sieving efficiency and insufficient sieving, which affects the quality of the sugar powder. Summary of the Invention

[0004] One object of this invention is to solve at least the aforementioned problems and / or defects, and to provide at least the advantages described below.

[0005] To address the shortcomings of existing technologies, this utility model provides a sugar powder sieving device, comprising:

[0006] The main body has an opening at the top and a first discharge port at the bottom;

[0007] The feed hopper is located above the main body; the feed hopper reciprocates along the length of the main body via a moving mechanism; the feed hopper includes an upper cavity and a lower cavity connected sequentially from top to bottom;

[0008] A flow regulating component is located in the lower cavity; the flow regulating component includes two symmetrically distributed inverted V-shape partitions and an adjusting member for adjusting the angle between the two partitions, and a discharge port is formed between the outer side of the partition and the side wall of the lower cavity; the upper end of the partition is hinged by a mounting shaft, and the adjusting member is located below the two partitions and can open or retract the partitions by adjusting the adjusting member;

[0009] A screen is disposed inside the main body and located below the feed hopper; a second discharge port is provided on the side wall of the main body on one side of the screen.

[0010] Preferably, the moving mechanism includes a first screw and a first guide rod. The first screw is rotatably mounted on the inner wall of the main body and extends through the main body to be connected to a forward and reverse motor. The first guide rod is fixed on the inner wall of the main body and is symmetrically distributed with the first screw relative to the feed hopper. Movable seats are provided on both sides of the outer wall of the upper cavity. One of the movable seats is spirally connected to the first screw, and the other movable seat is movably sleeved on the first guide rod.

[0011] Preferably, the bottom of the body is provided with an inclined guide plate, and the lowest inclined end of the guide plate is located at the bottom of the first discharge port.

[0012] Preferably, the adjusting component includes a support seat fixed in the lower cavity and located below the partition plate. The support seat is provided with a rotatable second screw, and a moving seat is screwed onto the second screw. The moving seat passes through a second guide rod on the support seat. The moving seat is provided with support heads on both sides in the length direction of the screen. The support heads abut against the lower surface of the partition plate to support the partition plate.

[0013] Preferably, the support base is provided with a drive shaft inside, one end of which is connected to the bottom end of the second screw through a transmission mechanism, and the other end of which passes through the lower cavity and is connected to the motor.

[0014] Preferably, an arched cover plate is provided above the mounting shaft, and the cover plate is fixed to the lower cavity sidewall on both sides in the width direction of the screen.

[0015] This utility model has at least the following beneficial effects: The main body of this utility model provides a sugar powder screening environment, and the first discharge port at the bottom of the main body is used to discharge the sugar powder that has passed through the screen; the feed hopper is used to feed the sugar powder to be screened into the screen, and the moving mechanism provides a power source to drive the feed hopper to move along the length of the main body, so that the moving feed hopper disperses the sugar powder onto the screen, effectively avoiding the accumulation of sugar powder at the drop point on the screen, which seriously affects the screening efficiency; at the same time, the flow regulating component is used to regulate the feeding flow rate of the feed hopper, and the feed hopper contains... The sugar powder falls onto the screen through the feeding port between the partition and the lower chamber side wall. By driving the adjusting component, the partition is opened to narrow the feeding port between the partition and the lower chamber side wall, or the partition is retracted to widen the feeding port between the partition and the lower chamber side wall. This allows for the regulation of the feeding flow rate of the hopper, facilitating the adjustment of the sugar powder throughput. It can also cause the partition to contact the lower chamber side wall to close the feeding port, enabling intermittent batch feeding of sugar powder. This ensures that the sugar powder falls onto the screen in batches and in a dispersed manner, guaranteeing the screen's screening efficiency.

[0016] By employing this utility model, the feeding hopper disperses the sugar powder under the action of the moving mechanism. At the same time, through the cooperation of the baffle and the adjusting component, the sugar powder is fed intermittently in batches and the feeding flow rate is adjusted. This allows the sugar powder to fall onto the screen in batches and in a dispersed manner, effectively reducing the phenomenon of sugar powder accumulating on the screen and causing slow screening efficiency, and improving the overall screening efficiency.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0025] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not imply the presence or addition of one or more other elements or combinations thereof.

[0026] See Figures 1 to 6A sugar powder sieving device includes a main body 100, a feed hopper 200, a flow regulating component 400, and a screen 500.

[0027] The main body 100 has an opening 110 at the top and a first discharge port 120 at the bottom. The first discharge port 120 is used to discharge sugar powder that has passed through the screen 500. The first discharge port 120 can be normally closed or normally open. The main body 100 provides a sugar powder screening environment. The main body 100 can be a cylindrical box, more preferably a rectangular box.

[0028] The feeding hopper 200 is located above the interior 100 of the main body; the feeding hopper 200 reciprocates along the length of the main body 100 via the moving mechanism 300; the feeding hopper 200 includes an upper cavity 210 and a lower cavity 220 connected sequentially from top to bottom, the upper cavity 210 preferably has a structure that is larger at the top and smaller at the bottom, and it forms a funnel-shaped structure with the lower cavity 220.

[0029] A flow regulating component 400 is located within the lower cavity 220. The flow regulating component 400 includes two symmetrically distributed inverted V-shape partitions 410 and an adjusting member 420 for adjusting the angle between the two partitions 410. A discharge port 230 is formed between the outer side of the partitions 410 and the side wall of the lower cavity 220. The upper ends of the partitions 410 are hinged by a mounting shaft 430, and both ends of the mounting shaft 430 are fixed to the side wall of the lower cavity 220. It can be understood that the two partitions 410 and the mounting shaft 430 are hinged. The adjusting member 420 is located below the two partitions 410 and opens or retracts the partitions 410.

[0030] A sieve 500 is disposed inside the body 100 and below the feed hopper 200. The shape of the sieve 500 is the same as that of the body 100. The sieve 500 is a prior art product. A second discharge port 130 is provided on the side wall of the body 100 on one side of the sieve 500. The second discharge port 130 is normally closed to prevent unscreened sugar powder from being discharged from the second discharge port 130.

[0031] Specifically, the feed hopper 200 is used to feed the sugar powder to be screened into the screen 500. The moving mechanism 300 provides a power source to drive the feed hopper 200 to move along the length of the body 100, thereby dispersing the sugar powder onto the screen 500, effectively preventing the sugar powder from falling onto the screen 500 in a concentrated manner and causing accumulation at the drop point, which would seriously affect the screening efficiency. At the same time, the flow regulating component 400 is used to regulate the discharge flow rate of the feed hopper 200. The sugar powder in the feed hopper 200 falls onto the screen 500 through the discharge port 230 between the partition 410 and the side wall of the lower cavity 220, and is then controlled by the drive mechanism. Adjusting component 420 expands partition 410, causing the discharge port 230 between partition 410 and the side wall of lower cavity 220 to narrow, or retracts partition 410, causing the discharge port 230 between partition 410 and the side wall of lower cavity 220 to widen. This allows for adjustment of the discharge flow rate of feed hopper 200, facilitating the regulation of the sugar powder throughput at discharge port 230. Furthermore, it allows partition 410 to contact the side wall of lower cavity 220, closing discharge port 230 and enabling intermittent, batch-wise sugar powder discharge. This ensures that the sugar powder falls onto screen 500 in batches and dispersedly, guaranteeing the efficient sieving of sugar powder by screen 500.

[0032] Based on the above, in some embodiments, the moving mechanism 300 includes a first screw 310 and a first guide rod 320. The first screw 310 is rotatably mounted on the inner wall of the body 100 and extends through the body 100 to connect with the forward and reverse motor 330. The first screw 310 extends along the length of the body 100. The forward and reverse motor 330 is a prior art product and is mounted on the outside of the body 100. The first guide rod 320 is fixed on the inner wall of the body 100 and is symmetrically distributed with the first screw 310 relative to the feed hopper 200. Movable seats 211 are respectively provided on both sides of the outer wall of the upper cavity 210. One of the movable seats 211 is spirally connected to the first screw 310, and the other movable seat 211 is movably sleeved on the first guide rod 320. In practical use, the forward and reverse motor 330 drives the first screw 310 to rotate, the rotating first screw 310 drives the movable seat 211 to move, and the movable seat 211 in turn drives the feed hopper 200 to move along the first screw 310. The other movable seat 211 cooperates with the first guide rod 320 to play a guiding role, making the movement of the feed hopper 200 more stable.

[0033] Based on the above, in some embodiments, an inclined guide plate 600 is provided at the bottom of the body 100, and the lowest inclined end of the guide plate 600 is located at the bottom of the first discharge port 120. The guide plate 600 is provided to facilitate the discharge of sugar powder that falls through the screen 500 from the body 100.

[0034] Based on the above, in some embodiments, the adjusting member 420 includes a support base 421 fixed within the lower cavity 220 and located below the partition plate 410. A rotatable second screw 422 is provided on the support base 421, and a moving seat 423 is helically connected to the second screw 422. The moving seat 423 also passes through a second guide rod 424 on the support base 421. Support heads 425 are provided on both sides of the moving seat 423 along the length of the screen 500. The support heads 425 abut against the lower surface of the partition plate 410 to support the partition plate 410. Preferably, a drive shaft 426 is provided inside the support base 421. One end of the drive shaft 426 is connected to the bottom end of the second screw 422 via a transmission mechanism, and the other end of the drive shaft 426 extends out of the lower cavity 220 and is connected to a motor. Specifically, the motor (not shown) is a prior art product. The motor is installed outside the lower cavity 220. The motor drives the transmission shaft 426 to rotate the second screw 422, which in turn causes the moving seat 423 to move up and down along the second screw 422, thereby driving the support head 425 to move up and down. As a result, when the support head 425 rises, the angle between the partitions 410 increases, and when the support head 425 falls, the angle between the partitions 410 decreases, thereby achieving the adjustment of the feed port 230.

[0035] It is understood that the transmission mechanism is existing technology, and as long as it can drive the second screw 422 to rotate by rotating the transmission shaft 426, no specific restrictions are imposed here. For ease of understanding, in this embodiment, the transmission mechanism can be a driving wheel and a driven wheel. The driving wheel is coaxially mounted on the transmission shaft 426, and the bottom end of the second screw 422 extends into the support base 421 and connects with the driven wheel. At the same time, the driving wheel and the driven wheel are meshed together. Through the cooperation of the driving wheel and the driven wheel, when the motor drives the transmission shaft 426 to rotate forward and reverse, it can drive the second screw 422 to rotate.

[0036] In practical use, to prevent powdered sugar from falling onto the connection between the mounting shaft 430 and the partition 410 and affecting the rotation of the partition 410, an arched cover plate 700 is provided above the mounting shaft 430. The cover plate 700 is fixed on the side wall of the lower cavity 220 on both sides of the screen 500 in the width direction. The cover plate 700 can effectively block the powdered sugar and prevent it from falling onto the mounting shaft 430. At the same time, the arched shape of the cover plate 700 facilitates the falling of the powdered sugar.

[0037] In practical use, the sugar powder to be sieved is poured into the feed hopper 200, and the forward and reverse motor 330 is started. The feed hopper 200 reciprocates within the body 100, and the sugar powder falls onto the screen 500 through the discharge port 230. The motor is started as needed to drive the moving seat 423 to move the support head 425, thereby adjusting the partition 410 and adjusting the diameter of the discharge port 230. The sugar powder falling evenly onto the screen 500 passes through the screen 500 and is discharged from the first discharge port 120. After sieving, the second discharge port 130 is opened to discharge the large sugar powder particles intercepted by the screen 500.

[0038] By employing this utility model, the feeding hopper 200, under the action of the moving mechanism 300, disperses the sugar powder. Simultaneously, through the cooperation of the partition 410 and the adjusting component 420, the sugar powder is fed intermittently in batches, and the feeding flow rate is adjusted. This allows the sugar powder to fall onto the screen 500 in batches and in a dispersed manner, effectively reducing the accumulation of sugar powder on the screen 500 and the resulting slow screening efficiency, thus improving the overall screening efficiency.

[0039] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and illustrations shown and described herein. Obviously, those skilled in the art can make various modifications and variations to this invention without departing from the spirit and scope of this invention.
