Description

Technical Field

[0001] This utility model relates to the technical field of corn crushing in the corn deep processing production process, and directly relates to an automatic feeding device for a corn degerming mill. Background Technology

[0002] Currently, in the corn deep processing production process, when wet corn enters the corn degerminator, the traditional process relies on valves or baffles to adjust the feeding amount. Manual adjustment is labor-intensive, and the adjustment is not timely enough and the accuracy is difficult to control. This can easily cause the corn degerminator to not operate at full capacity or to shut down due to overload, thus damaging the equipment. Therefore, it is essential to study an automatic feeding device for the corn degerminator. Summary of the Invention

[0003] The purpose of this invention is to address the problems of relying on gate valves or manual baffles to adjust the feeding amount of corn degerming mills, which leads to delayed adjustments, insufficient or excessive load on the mill, and equipment failure. The invention aims to develop an automatic feeding device for corn degerming mills, the technical solution of which is as follows:

[0004] This utility model discloses an automatic feeding device for a corn degerming mill, comprising a corn inlet pipe 1, a radar level gauge 2, a corn hopper 3, a corn outlet pipe 4, a maintenance gate valve 5, a frequency conversion rotary valve 6, a gluten water pipe 7, a corn degerming mill 8, a corn slurry tank 9, a corn slurry pump 10, and a control module 11. The corn inlet pipe 1 is connected to the top inlet of the corn hopper 3. The radar level gauge 2 is installed on the top of the corn hopper 3. The bottom outlet of the corn hopper 3 is connected to the corn outlet pipe 4. The corn outlet pipe 4 is connected to the maintenance gate valve 5 and the frequency conversion rotary valve 6 via flanges, and then to the feeding port of the corn degerming mill 8. The gluten water pipe 7 is connected to the corn outlet pipe 4 at the feeding port of the corn degerming mill 8. The outlet of the corn degerming mill 8 is connected to the corn slurry tank 9 via a pipe. The outlet of the corn slurry tank 9 is connected to the corn slurry pump 10 via a pipe and a valve. The control module 11, the radar level gauge 2, the frequency conversion rotary valve 6, and the corn degerming mill 8 are electrically connected.

[0005] Furthermore, the maintenance gate valve 5 is normally in the open state. When the equipment is shut down for maintenance, the maintenance gate valve 5 is closed to ensure maintenance safety. The maintenance gate valve 5 is the backup valve for the frequency converter rotary valve 6.

[0006] Furthermore, the full-load feeding capacity of the variable frequency rotary valve 6 is 1.2 times the rated crushing capacity of the corn degerming mill 8, ensuring adjustment space during the feeding process.

[0007] The purpose of this invention is achieved as follows: Qualified corn enters the corn silo through the corn feed pipe. After the radar level gauge senses the rise in the silo level, it transmits the signal to the control module. The control module, according to the set program, sends a signal to start the frequency converter rotary valve and operate at the set frequency. At the same time, the corn degerming mill current is continuously fed back to the control module. When the corn degerming mill current is lower than 70% of the rated current of the motor, the control module sends an increase signal to the frequency converter rotary valve according to the set program. When the corn degerming mill current is higher than 100% of the rated current of the motor, the control module sends a decrease signal to the frequency converter rotary valve according to the set program. When the corn degerming mill current is between 80% and 90% of the rated current, the control module maintains the rotation speed of the frequency converter rotary valve unchanged according to the set program, ensuring that the corn degerming mill operates at a load between 80% and 90%, thus ensuring the optimal output rate of the corn degerming mill.

[0008] Furthermore, the corn slurry crushed by the corn degerming mill enters the corn slurry tank, and is then pressurized by the corn slurry pump and sent to the next process. The entire crushing process of the corn degerming mill is controlled by the control module according to the set program, which adjusts the feeding speed of the variable frequency rotary valve to ensure the optimal operating load of the corn degerming mill (between 80% and 90%).

[0009] The beneficial effects of this utility model are: by adding an automatic feeding device with a variable frequency rotary valve to the corn degerming mill, the rotation speed (feeding amount) of the variable frequency rotary valve can be adjusted in a timely manner according to the current of the corn degerming mill through the program set in the control module, thereby adjusting the current of the corn degerming mill and ensuring that the current of the corn degerming mill is within the optimal operating range (between 80% and 90%), thus achieving the best operating efficiency of the corn degerming mill.

[0013] Now combined with the appendix Figure 1 The present invention provides a further description of an automatic feeding device for a corn degerming mill.

[0014] This utility model discloses an automatic feeding device for a corn degerming mill, comprising a corn inlet pipe 1, a radar level gauge 2, a corn hopper 3, a corn outlet pipe 4, a maintenance gate valve 5, a frequency conversion rotary valve 6, a gluten water pipe 7, a corn degerming mill 8, a corn slurry tank 9, a corn slurry pump 10, and a control module 11. The corn inlet pipe 1 is connected to the top inlet of the corn hopper 3. The radar level gauge 2 is installed on the top of the corn hopper 3. The bottom outlet of the corn hopper 3 is connected to the corn outlet pipe 4. The corn outlet pipe 4 is connected to the maintenance gate valve 5 and the frequency conversion rotary valve 6 via flanges, and then to the feeding port of the corn degerming mill 8. The gluten water pipe 7 is connected to the corn outlet pipe 4 at the feeding port of the corn degerming mill 8. The outlet of the corn degerming mill 8 is connected to the corn slurry tank 9 via a pipe. The outlet of the corn slurry tank 9 is connected to the corn slurry pump 10 via a pipe and a valve. The control module 11, the radar level gauge 2, the frequency conversion rotary valve 6, and the corn degerming mill 8 are electrically connected.

[0015] The working principle of this utility model is as follows: Qualified corn enters the corn silo. After the radar level gauge senses the rise in the silo level, the signal is transmitted to the control module. The control module, according to the set program, sends a signal to start the frequency converter rotary valve and operate at the set frequency. At the same time, the corn degerming mill current is continuously fed back to the control module. When the corn degerming mill current is lower than 70% of the rated current of the motor, the control module sends an increase signal to the frequency converter rotary valve according to the set program. When the corn degerming mill current is higher than 100% of the rated current of the motor, the control module sends a decrease signal to the frequency converter rotary valve according to the set program. When the corn degerming mill current is between 80% and 90% of the rated current, the control module maintains the rotation speed of the frequency converter rotary valve unchanged according to the set program, ensuring that the corn degerming mill operates at a load between 80% and 90%, thus ensuring the optimal output rate of the corn degerming mill.

[0016] This invention adds an automatic feeding device with a variable frequency rotary valve to the corn degerming mill. Based on the current of the corn degerming mill, the speed (feeding amount) of the variable frequency rotary valve can be adjusted in a timely manner through a program set in the control module, thereby adjusting the current of the corn degerming mill and ensuring that the current of the corn degerming mill is within the optimal operating range (between 80% and 90%), thus achieving the best operating efficiency of the corn degerming mill.
