Technical Field

[0001] This utility model relates to the field of corn fiber production technology, specifically to a corn fiber moisture squeezing control system. Background Technology

[0002] Corn starch factories employ a corn soaking and wet milling process. The main product is starch, with byproducts including corn gluten meal, corn germ, corn fiber, and corn steep liquor. Corn fiber is obtained through washing, dehydration, drying, pulverizing, and packaging to obtain commercial fiber, which is used as a feed ingredient. Currently, fiber extruders are commonly used to dehydrate and squeeze the fiber. However, the moisture content after squeezing is unstable, fluctuating between 53% and 58%, resulting in poor product quality and high energy consumption. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a corn fiber desqueezing control system that addresses the shortcomings of existing technologies, resulting in high-quality products with low energy consumption.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A corn fiber moisture squeezing control system includes a fiber extruder, the inlet of which is connected to a material cylinder, a large shaft passing through the lower part of the material cylinder, one end of which is connected to a motor shaft, and the other end of which is provided with a small shaft, and one outer end of which is connected to a bearing seat disposed on the inner wall of the fiber extruder.

[0006] A resistance cone is fitted on the outer side of the main shaft at the outlet of the fiber extruder. A discharge gap is formed between the outer wall of the resistance cone and the outlet of the fiber extruder. A hydraulic cylinder is connected to one end of the outer side of the resistance cone on the inner wall of the fiber extruder.

[0007] As an improved technical solution, two hydraulic cylinders are provided, symmetrically arranged along the axis of the resistance cone.

[0008] As an improved technical solution, the main shaft is provided with an auger on the outer side of a section inside the barrel.

[0009] As an improved technical solution, the auger is a conical auger, the auger blade height at the feed end of the barrel is 10cm, the auger blade height at the discharge end of the barrel is 2cm, and the barrel is provided with a conical screen on the outside of the auger, the screen being adapted to the shape of the auger.

[0010] As an improved technical solution, a material level sensor is installed inside the material cylinder, and a switching valve is installed on the material cylinder's feed pipe. The material level sensor and the switching valve are interlocked to the control system.

[0011] As an improved technical solution, the discharge end of the fiber extruder is equipped with an online moisture detection sensor, and the online moisture detection sensor is interlocked with the hydraulic cylinder to the control system.

[0012] As a preferred technical solution, the discharge end of the fiber extruder is equipped with an online moisture detection sensor, and the online moisture detection sensor is interlocked with the motor to the control system.

[0013] As a preferred technical solution, the discharge end of the fiber extruder is equipped with an online moisture detection sensor, and the online moisture detection sensor, the motor and the hydraulic cylinder are interlocked to the control system.

[0014] As a preferred technical solution, the discharge end of the fiber extruder is provided with a guide trough, and the angle between the guide trough and the horizontal is 70-80°.

[0015] Due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] This utility model discloses a corn fiber moisture-removing control system, comprising a fiber extruder. The inlet of the fiber extruder is connected to a material cylinder, and a large shaft runs through the lower part of the material cylinder. One end of the large shaft is connected to a motor shaft, and the other end of the large shaft has a small shaft. A bearing seat mounted on the inner wall of the fiber extruder is connected to the outer end of the small shaft. A resistance cone is fitted onto the outer side of the large shaft at the outlet of the fiber extruder, forming a discharge gap between the outer wall of the resistance cone and the outlet of the fiber extruder. A hydraulic cylinder mounted on the inner wall of the fiber extruder is connected to the outer end of the resistance cone. The large shaft is driven by the motor to rotate, which in turn drives the material to be conveyed within the fiber extruder. The discharge gap formed between the resistance cone and the fiber extruder outlet controls the extrusion speed and pressure. The resistance cone can slide along the axial direction of the large shaft, and its position can be adjusted using the hydraulic cylinder, thereby adjusting the size of the discharge gap. This effectively controls the moisture-removing process of the corn fiber, ensuring the desired drying effect.

[0017] The present invention comprises two hydraulic cylinders, symmetrically arranged along the axis of the resistance cone. The two hydraulic cylinders symmetrically arranged along the axis of the resistance cone ensure uniform force distribution on the resistance cone, making the adjustment of the resistance cone position more stable and reliable, preventing tilting or displacement of the resistance cone, thereby ensuring the consistency of the discharge gap in the circumferential direction and improving the quality and stability of moisture removal from corn fibers.

[0018] The main shaft is located on the outer side of a section inside the barrel, where an auger is installed. The auger propels the corn fiber material inside the barrel forward as the main shaft rotates, achieving continuous material conveying and ensuring that the material can smoothly enter the fiber extruder for moisture removal, thereby improving the overall system efficiency.

[0019] The auger is a conical auger. The auger blade height at the feed end of the barrel is 10cm, and the auger blade height at the discharge end of the barrel is 2cm. A conical screen is provided on the outside of the auger, and the screen is adapted to the shape of the auger. The blade height of the conical auger gradually decreases from the feed end to the discharge end, which can generate gradually increasing extrusion pressure on the corn fiber material. In conjunction with the conical screen, some moisture can be initially squeezed out during the material conveying process, improving the subsequent desqueezing efficiency of the fiber extruder. At the same time, the screen can filter out some impurities and moisture.

[0020] The material cylinder is equipped with a level sensor inside, and a switching valve is installed on the feed pipe of the material cylinder. The level sensor and the switching valve are interlocked to the control system. The level sensor can monitor the material level in the material cylinder in real time. When the material level reaches the set value, the switching valve is closed through the control system to stop feeding; when the material level is lower than the set value, the switching valve is opened to feed, realizing automatic control of the material level in the material cylinder and avoiding excessive or insufficient material in the material cylinder from affecting the normal operation of the system.

[0021] The fiber extruder is equipped with an online moisture detection sensor at the discharge end, which is interlocked with the hydraulic cylinder to the control system. The online moisture detection sensor can detect the moisture content of the extruded material in real time. When the moisture content does not meet the requirements, the control system can interlock the hydraulic cylinder to adjust the position of the resistance cone and the size of the discharge gap based on the detection result, thereby changing the extrusion pressure to bring the moisture content of the extruded material to the expected target, achieving real-time adjustment of the moisture-removing effect.

[0022] The fiber extruder is equipped with an online moisture detection sensor at the discharge end, which is interlocked with the motor to the control system. The online moisture detection sensor monitors the moisture content of the extruded material. When the moisture content is abnormal, the control system can interlock and adjust the motor speed, changing the rotation speed of the main shaft. This adjusts the material conveying speed and squeezing time within the fiber extruder, thereby controlling the moisture content of the extruded material and improving the system's intelligent control level.

[0023] The fiber extruder is equipped with an online moisture detection sensor at the discharge end. This sensor, along with the motor and hydraulic cylinder, is interlocked with the control system. This multi-component interlocking control method comprehensively utilizes the detection results from the online moisture sensor, simultaneously adjusting the motor speed and hydraulic cylinder movement to achieve precise control of the corn fiber drying process. Based on real-time changes in material moisture content, parameters such as material conveying speed and extrusion pressure can be flexibly adjusted to ensure the moisture content of the extruded material remains stable within a set range, thereby improving product quality and production efficiency.

[0024] The fiber extruder is equipped with a guide chute at the discharge end, with the guide chute forming an angle of 70-80° with the horizontal. This specific angle allows the extruded corn fiber material to slide smoothly down under gravity, preventing material accumulation at the discharge end and ensuring smooth discharge. Simultaneously, the appropriate tilt angle helps reduce friction between the material and the guide chute, improving material conveying efficiency. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] like Figure 1-2 As shown, a corn fiber moisture-removing control system includes a fiber extruder 1. The inlet of the fiber extruder 1 is connected to a material cylinder 2. A large shaft 3 is installed through the lower part of the material cylinder 2. One end of the large shaft 3 is connected to the rotating shaft of a motor 4. The other end of the large shaft 3 is provided with a small shaft 5. One outer end of the small shaft 5 is connected to a bearing seat 6 provided on the inner wall of the fiber extruder 1. A resistance cone 7 is sleeved on the outer side of the large shaft 3 at the outlet of the fiber extruder 1. A discharge gap 8 is formed between the outer wall of the resistance cone 7 and the outlet of the fiber extruder 1. One outer end of the resistance cone 7 is connected to a hydraulic cylinder 9 provided on the inner wall of the fiber extruder 1. The main shaft 3 is driven to rotate by the motor 4, which can drive the material to be conveyed in the fiber extruder 1. The discharge gap 8 formed by the resistance cone 7 and the outlet of the fiber extruder 1 can control the speed and pressure of the material extrusion. The resistance cone 7 can slide along the axial direction of the main shaft 3. The position of the resistance cone 7 can be adjusted in conjunction with the hydraulic cylinder 9, thereby adjusting the size of the discharge gap 8, so as to effectively control the process of squeezing out the moisture of corn fiber and ensure the squeezing effect.

[0031] Two hydraulic cylinders 9 are provided, symmetrically arranged along the axis of the resistance cone 7. The two hydraulic cylinders 9 symmetrically arranged along the axis of the resistance cone 7 can make the resistance cone 7 bear force evenly, making the adjustment of the position of the resistance cone 7 more stable and reliable, avoiding tilting or displacement of the resistance cone 7, thereby ensuring the consistency of the discharge gap 8 in the circumferential direction and improving the quality and stability of squeezing moisture from corn fiber.

[0032] The main shaft 3 is located on the outer side of a section inside the material cylinder 2, where an auger 10 is installed. The auger 10 can propel the corn fiber material in the material cylinder 2 forward when the main shaft 3 rotates, realizing continuous material conveying, ensuring that the material can smoothly enter the fiber extruder 1 for dewatering, and improving the working efficiency of the entire system.

[0033] The auger 10 is a conical auger 10. The blade height of the auger 10 at the feed end of the barrel 2 is 10cm, and the blade height at the discharge end of the barrel 2 is 2cm. A conical screen 11 is provided on the outside of the auger 10, and the screen 11 is adapted to the shape of the auger 10. The blade height of the conical auger 10 gradually decreases from the feed end to the discharge end, which can generate gradually increasing extrusion pressure on the corn fiber material. In conjunction with the conical screen 11, some moisture can be initially squeezed out during the material conveying process, improving the squeezing efficiency of the subsequent fiber extruder 1. At the same time, the screen 11 can filter out some impurities and moisture.

[0034] The material cylinder 2 is equipped with a material level sensor 12 inside, and a switching valve 13 is installed on the feed pipe of the material cylinder 2. The material level sensor 12 and the switching valve 13 are interlocked to the control system. The material level sensor 12 can monitor the material level in the material cylinder 2 in real time. When the material level reaches the set value, the switching valve 13 is closed through the control system to stop feeding; when the material level is lower than the set value, the switching valve 13 is opened to feed, realizing automatic control of the material level in the material cylinder 2 and avoiding excessive or insufficient material in the material cylinder 2 from affecting the normal operation of the system.

[0035] The fiber extruder 1 is equipped with an online moisture detection sensor 14 at its discharge end. The online moisture detection sensor 14 is interlocked with the hydraulic cylinder 9 to the control system. The online moisture detection sensor 14 can detect the moisture content of the extruded material in real time. When the moisture content does not meet the requirements, the control system can interlock the hydraulic cylinder 9 to adjust the position of the resistance cone 7 and the size of the discharge gap 8 based on the detection result, thereby changing the extrusion pressure to make the moisture content of the extruded material reach the expected target, thus achieving real-time adjustment of the moisture-removing effect.

[0036] The fiber extruder 1 is equipped with an online moisture detection sensor 14 at its discharge end. The online moisture detection sensor 14 is interlocked with the motor 4 to the control system. By detecting the moisture content of the extruded material through the online moisture detection sensor 14, when the moisture content is abnormal, the control system can interlock and adjust the rotation speed of the motor 4, thereby changing the rotation speed of the main shaft 3. This adjusts the conveying speed and squeezing time of the material in the fiber extruder 1, achieving the purpose of controlling the moisture content of the extruded material and improving the intelligent control level of the system.

[0037] More preferably, the fiber extruder 1 is equipped with an online moisture detection sensor 14 at its discharge end. The online moisture detection sensor 14, the motor 4, and the hydraulic cylinder 9 are interlocked with the control system. This multi-component interlocking control method comprehensively utilizes the detection results of the online moisture detection sensor 14, simultaneously adjusting the speed of the motor 4 and the action of the hydraulic cylinder 9 to achieve precise control of the moisture-removing process of the corn fiber. Based on real-time changes in material moisture content, parameters such as material conveying speed and extrusion pressure can be flexibly adjusted to ensure that the moisture content of the extruded material remains stable within the set range, thereby improving product quality and production efficiency.

[0038] The fiber extruder 1 has a guide chute 15 at its discharge end, with the guide chute 15 forming an angle of 70-80° with the horizontal. This specific angle of the guide chute 15 allows the extruded corn fiber material to slide smoothly down under gravity, preventing material accumulation at the discharge end and ensuring smooth discharge. Simultaneously, the appropriate tilt angle helps reduce friction between the material and the guide chute 15, improving material conveying efficiency.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
