Description

Technical Field

[0001] This invention relates to the field of spiral feeding technology, specifically to a spiral feeding device for rice processing. Background Technology

[0002] A screw feeder is a mechanical device that uses rotating helical blades to push and convey materials within a closed cylinder. Due to its advantages such as simple structure, small cross-sectional area, good sealing, convenient operation, and multiple loading and unloading points, it is widely used in various stages of rice processing, including cleaning, hulling, milling, polishing, grading, and packaging. A motor drives the screw shaft to rotate, causing the material added to the trough to move forward along the bottom of the trough under the push of the helical blades. The movement of the material is similar to the translational motion of a non-rotating nut along a rotating screw. Finally, the material is lifted or horizontally conveyed to the discharge port during the conveying process. It connects to different equipment in the production line, such as conveying cleaned paddy to the huller, or lifting material from a low position to a high position, such as lifting brown rice to the inlet of the rice milling machine. By controlling the speed of the screw shaft, precise and continuous quantitative feeding of the material can be achieved, and it is often used in rice blending or packaging processes.

[0003] Current rice conveying equipment is prone to clogging due to friction between rice grains, and broken rice is usually not screened during the screening process. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a spiral feeding device for rice processing, comprising a device support, a feeding device fixedly connected to the top of the device support, a dispersing device connected to the top of the feeding device, a dust removal device connected to the side of the feeding device, and the side of the dust removal device being fixedly connected to the side of the device support through the support.

[0005] The feeding device includes a feeding base, a first motor fixedly connected to the side of the feeding base, a feeding pipe fixedly connected to the side of the feeding base away from the first motor, a spiral blade fixedly connected to the drive shaft of the first motor, a screening pipe fixedly connected to the side of the feeding pipe, and the bottom of the feeding base fixedly connected to the top of the equipment support. When the first motor is started, the first motor rotates, causing the rice falling inside the feeding pipe to move, thereby driving the rice into the interior and completing the rice conveying. The variable cross-section design of the feeding pipe reduces the pressure during the spiral conveying of the rice, thus reducing the possibility of blockage.

[0006] Preferably, the helical blade includes a rotating base, a narrow blade is fixedly connected to the side of the rotating base, a variable cross-section blade is fixedly connected to the side of the narrow blade, and the side of the rotating base is fixedly connected to the drive shaft of the first motor.

[0007] Preferably, the screening tube includes a screen tube with a broken rice sieve hole at the bottom and a dust sieve hole at the top. A discharge hole is provided on the side of the screen tube, and a conical tube is connected to the side of the screen tube away from the discharge hole. The end of the conical tube away from the screen tube is connected to the side of the feeding tube. The variable cross-section blade extends into the interior of the screen tube and is slidably connected to it. The drive shaft of the first motor rotates, causing the rotating base to rotate. The rotating base rotates, causing the narrow blade to rotate. The narrow blade rotates, causing the variable cross-section blade to rotate. The narrow blade propels the rice in a spiral motion, and the variable cross-section blade also propels the rice in a spiral motion, thereby reducing the pressure during rice transport and facilitating rice transport. Furthermore, the rice is screened inside the screen tube through the broken rice sieve hole and the dust sieve hole. As the variable cross-section blade moves the rice, it moves along the side of the broken rice sieve hole, thus screening out broken rice from the whole rice and removing impurities during rice transport, facilitating high-quality rice processing.

[0008] Preferably, the dispersing device includes a feed pipe, the bottom of which is connected to a dispersing component. A dust collection component is fitted and fixedly connected to the side of the dispersing component. A ventilation pipe is connected to the side of the dust collection component, and the air inlet of a first fan is connected to the side of the ventilation pipe. A connecting pipe is connected to the bottom of the dust collection component, and the bottom of the connecting pipe is connected to the top of the feed pipe. Preferably, the dispersing device includes a feed pipe, which is typically made of wear-resistant and corrosion-resistant stainless steel, used to convey the material to be processed from top to bottom to the dispersing area. The bottom of the feed pipe is connected to the dispersing component, which typically includes a high-speed rotating dispersing disc or dispersing teeth, driven by a motor, capable of strongly shearing and impacting the falling material, achieving uniform dispersion and preliminary crushing of the material. A dust collection component is fitted and fixedly connected to the side of the dispersing component. The dust collection component is typically designed as a ring-shaped cover structure, surrounding the dispersing area, effectively covering the area where dust is generated. A guide plate or filter structure may be provided on its inner side to enhance the capture ability of fine particles. The main function of the dust collection assembly is to collect the dust generated during material dispersion in a timely manner, preventing dust spillage, ensuring a clean working environment, and reducing material loss. A ventilation duct is connected to the side of the dust collection assembly, with the other end connected to the air inlet of the primary fan. After the primary fan starts, a negative pressure environment is created inside the dust collection assembly, causing the dust raised during dispersion to be drawn into the dust collection hood with the airflow and discharged through the ventilation duct. The ventilation duct can be designed as a fixed elbow or a flexible pipe according to system layout requirements, with sealed connections to ensure the airtightness of the entire ventilation system. A connecting pipe, typically vertical or inclined, is connected to the bottom of the dust collection assembly, its bottom connecting to the top of the feeding pipe. The dispersed material, along with the collected coarser particles, falls into the connecting pipe under the combined action of gravity and negative pressure airflow, ultimately entering the feeding pipe and being transported to the next process or collection device. This design achieves integrated operation of dispersion, dust removal, and conveying, significantly improving production efficiency and is suitable for the powder material processing needs of various industries such as chemical, food, and pharmaceutical industries.

[0009] Preferably, the dispersing component includes a feeding pipe, a conical screen is fixedly connected to the bottom of the feeding pipe, an arc-shaped fan blade is fixedly connected to the top of the conical screen, a dispersing tip is connected to the bottom of the arc-shaped fan blade, the bottom of the feeding pipe is fixedly connected to the top of the ventilation pipe, and the side of the feeding pipe is fixedly connected to the inner wall of the feed pipe.

[0010] Preferably, the dust collection assembly includes a collection pipe with filter holes on its side. A support plate is fixedly connected to the top of the inner wall of the collection pipe, and an arc-shaped filter plate is fixedly connected to the bottom of the support plate. The side of the collection pipe is fixedly connected to the side of the ventilation pipe, and the top of the support plate contacts the bottom of the conical screen. When the first fan is started, the first fan drives air through the feed pipe into the interior of the conical screen, through the arc-shaped filter plate, and into the interior of the collection pipe. Under the action of the first fan, the air is also driven through the filter holes into the interior of the ventilation pipe. Rice is then poured in from the top of the feeding pipe and... Under the action of force, the dust is first separated at the top of the conical screen, and the rice is dispersed by the arc-shaped fan blades, which facilitates the separation of the rice and prevents problems such as clumping caused by moisture in the rice. The rice is also guided by the arc-shaped fan blades and spirally guided, which facilitates the conveying of the rice. The support plate supports the conical screen, the arc-shaped filter plate collects the dust, and the filter holes separate the air and dust, so that the dust in the rice is separated from the air and keeps the dust inside the collection tube, which facilitates the centralized treatment of the dust.

[0011] Preferably, the dust removal device includes an upper dust removal shell, a lower guide shell fixedly connected to the bottom of the upper dust removal shell, a partition plate fixedly connected to the inner wall side of the upper dust removal shell, a guide cylinder connected to the bottom of the lower guide shell, a second fan connected to the side of the upper dust removal shell, a screen tube extending into the interior of the upper dust removal shell and fixedly connected to the inner wall of the upper dust removal shell through the partition plate, and the side of the upper dust removal shell fixedly connected to the side of the equipment support through a bracket. When the second fan is started, the second fan rotates and drives air from the bottom of the guide cylinder through the screen tube to the top of the upper dust removal shell and is discharged along the side of the second fan, thereby separating the dust generated during the conveying in the screen tube. Furthermore, the broken rice is screened through the broken rice sieve holes and falls naturally along the inner wall of the guide cylinder under the action of gravity. The partition plate prevents the dust from falling and re-merging with the rice.

[0012] This invention provides a screw feeding device for rice processing. It has the following beneficial effects:

[0013] 1. This screw conveyor for rice processing is equipped with a first motor. The rotation of the first motor drives the screw conveyor to move the rice falling inside the feeding pipe, thereby driving the rice into the interior and completing the conveying of the rice. The variable cross-section design of the feeding pipe reduces the pressure during the screw conveying of rice, thereby reducing the possibility of blockage.

[0014] 2. This spiral feeding device for rice processing is equipped with a first motor whose drive shaft rotates to drive a rotating base, which in turn drives a narrow blade to rotate. The narrow blade then drives a variable cross-section blade to rotate, which in turn propels the rice spirally. This spiral propels the rice, thereby reducing the pressure during rice transport and facilitating its conveying. Furthermore, the rice passes through broken rice and dust sieves inside the screen tube. As the variable cross-section blades move the rice, they also move it along the sides of the broken rice sieves, further filtering out broken rice from the whole grains. This process removes impurities during rice transport, ensuring high-quality rice processing.

[0015] 3. This spiral feeding device for rice processing is equipped with a first fan. The first fan drives air through the feed pipe into the conical screen, through the arc-shaped filter plate, and into the collection pipe. Under the action of the first fan, the air also passes through the filter holes into the ventilation pipe. Rice is poured in from the top of the feed pipe and, under the action of gravity, passes through the top of the conical screen where dust is initially separated. The arc-shaped fan blades further disperse the rice, facilitating separation and preventing clumping caused by moisture in the rice. The arc-shaped fan blades also guide the rice in a spiral motion, facilitating its transport. A support plate supports the conical screen, the arc-shaped filter plate collects dust, and the filter holes separate air and dust, thus separating dust from the air and concentrating it inside the collection pipe for centralized dust processing.

[0016] 4. This screw conveyor for rice processing is equipped with a second fan. The rotation of the second fan drives air from the bottom of the guide cylinder through the screen tube to the top of the upper dust collector and is discharged along the side of the second fan, thereby separating the dust generated during conveying in the screen tube. Broken rice is screened through the broken rice screen holes and falls naturally along the inner wall of the guide cylinder under the action of gravity. The partition plate prevents dust from falling and re-merging with the rice. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-2 The present invention provides a technical solution: a spiral feeding device for rice processing, including a device support 1, a feeding device 2 fixedly connected to the top of the device support 1, a dispersing device 3 connected to the top of the feeding device 2, a dust removal device 4 connected to the side of the feeding device 2, and the side of the dust removal device 4 fixedly connected to the side of the device support 1 through the support.

[0028] Equipment support frame 1 provides overall support for the equipment, feeding device 2 propels the rice in a spiral motion, dispersing device 3 removes dust and disperses the rice, and dust removal device 4 screens and removes broken rice while absorbing dust generated during rice collisions, thereby further improving rice quality. The variable cross-section design of feeding device 2 avoids rice compression during transportation, facilitating rice transport. After transportation, the rice undergoes two processes: dust removal and screening, thus improving rice quality and facilitating subsequent high-quality processing.

[0029] The feeding device 2 includes a feeding base 201, a first motor 202 is fixedly connected to the side of the feeding base 201, a feeding pipe 203 is fixedly connected to the side of the feeding base 201 away from the first motor 202, a spiral blade 204 is fixedly connected to the drive shaft of the first motor 202, a screening pipe 206 is fixedly connected to the side of the feeding pipe 203, and the bottom of the feeding base 201 is fixedly connected to the top of the equipment support 1.

[0030] The first motor 202 is started, and the rotation of the first motor 202 drives the spiral blade 204 to rotate. The rotation of the spiral blade 204 moves the rice that falls inside the feeding pipe 203, thereby driving the rice into the screening pipe 206, thus completing the conveying of the rice. The variable cross-section design of the feeding pipe 203 and the screening pipe 206 reduces the pressure during the spiral conveying of the rice, thereby reducing the possibility of blockage.

[0031] Please see Figures 1-4 The present invention provides a technical solution: the spiral blade 204 includes a rotating base 2041, a narrow blade 2042 is fixedly connected to the side of the rotating base 2041, a variable cross-section blade 2043 is fixedly connected to the side of the narrow blade 2042, and the side of the rotating base 2041 is fixedly connected to the drive shaft of the first motor 202.

[0032] The screening tube 206 includes a screen tube 2061, with a broken rice screening hole 2062 at the bottom and a dust screening hole 2063 at the top. A discharge hole 2064 is provided on the side of the screen tube 2061. A tapered tube 2065 is connected to the side of the screen tube 2061 away from the discharge hole 2064. The end of the tapered tube 2065 away from the screen tube 2061 is connected to the side of the feeding tube 203. A variable cross-section blade 2043 extends into the interior of the screen tube 2061 and is slidably connected to the screen tube 2061.

[0033] The drive shaft of the first motor 202 rotates, causing the rotating base 2041 to rotate. The rotation of the rotating base 2041 causes the narrow blade 2042 to rotate, which in turn causes the variable cross-section blade 2043 to rotate. The narrow blade 2042 propels the rice in a spiral motion, and the variable cross-section blade 2043 also propels the rice in a spiral motion, thereby reducing the pressure during rice transport and facilitating the transport of the rice. Inside the screen tube 2061, the rice is screened through the broken rice screen hole 2062 and the dust screen hole 2063. As the variable cross-section blade 2043 moves the rice, it moves along the side of the broken rice screen hole 2062, thereby screening out broken rice from the whole rice and removing impurities during the rice transport process, thus facilitating high-quality rice processing.

[0034] Please see Figures 1-7 The present invention provides a technical solution: the dispersing device 3 includes a feed pipe 301, the bottom of the feed pipe 301 is connected to a dispersing component 302, a dust collection component 303 is sleeved and fixedly connected to the side of the dispersing component 302, a ventilation pipe 304 is connected to the side of the dust collection component 303, the air inlet of a first fan 305 is connected to the side of the ventilation pipe 304, and a connecting pipe 306 is connected to the bottom of the dust collection component 303, the bottom of the connecting pipe 306 is connected to the top of the feeding pipe 203.

[0037] The first fan 305 is started, and it draws air through the feed pipe 301 into the conical screen 3022. The air then passes through the arc-shaped filter plate 3034 and reaches the collection pipe 3031. Under the action of the first fan 305, the air passes through the filter holes 3032 and enters the ventilation pipe 304. Rice is then poured in from the top of the feed pipe 3021 and, under gravity, passes through the top of the conical screen 3022, where dust is initially separated. The rice is then dispersed by the arc-shaped fan blades 3023, making it easier for the rice to be processed. Separation is performed to prevent clumping caused by moisture in the rice. The rice is guided by the arc-shaped fan blades 3023 and spirally guided, facilitating rice transport. The support plate 3033 supports the conical screen 3022. The arc-shaped filter plate 3034 collects dust, and the filter holes 3032 separate air and dust, thus separating dust from the air in the rice and keeping the dust inside the collection pipe 3031 for centralized dust treatment.

[0038] Please see Figures 1-8 The present invention provides a technical solution: the dust removal device 4 includes an upper dust removal shell 401, a lower guide shell 402 is fixedly connected to the bottom of the upper dust removal shell 401, a partition plate 403 is fixedly connected to the inner wall side of the upper dust removal shell 401, a guide cylinder 404 is connected to the bottom of the lower guide shell 402, a second fan 405 is connected to the side of the upper dust removal shell 401, a screen tube 2061 extends into the interior of the upper dust removal shell 401 and is fixedly connected to the inner wall of the upper dust removal shell 401 through the partition plate 403, and the side of the upper dust removal shell 401 is fixedly connected to the side of the equipment support 1 through a bracket.

[0039] The second fan 405 is started. The rotation of the second fan 405 drives the air from the bottom of the guide cylinder 404 through the screen pipe 2061 to the top of the upper dust collector 401 and is discharged along the side of the second fan 405, thereby separating the dust generated during the conveying in the screen pipe 2061. The broken rice is screened through the broken rice screen hole 2062 and falls naturally along the inner wall of the guide cylinder 404 under the action of gravity. The partition plate 403 is set to prevent the dust from falling and re-merging with the rice.
