Description

Technical Field

[0001] The utility model relates to a grain processing machine, in particular to a continuous unpowered rice cooler. Background Art

[0002] There are currently two ways to cool rice, one is the static method and the other is the dynamic method. The static method occupies a large area, has high cost, slow cooling speed, long cooling time, and uneven cooling; while the dynamic method mainly relies on the weight of the rice to achieve material discharge, with a fast material discharge speed, short cooling time, and poor cooling effect. Whether it is a static method rice cooling equipment or a dynamic method rice cooling equipment, there is usually only one set of feeding and discharging mechanisms, or the discharging mostly uses mechanical power to ensure the overall flow, but the use of a mechanical power structure increases energy consumption and damage to rice. At the same time, there is also a phenomenon of rice arching in large rice cooling warehouses, that is, a large amount of rice is piled up or bridged, thereby blocking the material discharge channel.

[0040] A plurality of cleaning platforms 7 are arranged in the warehouse body, and the cleaning platforms 7 are arranged in sequence from top to bottom, and a cleaning door 14 is arranged on the side wall of the warehouse body facing the cleaning platform 7. The cleaning platform 7 is fixed inside the warehouse body 6 and used in conjunction with the cleaning door 14 for manual cleaning inside the warehouse. The steel grid structure is adopted and rice is not accumulated; when it is inconvenient to open the door outside, a ladder will be installed inside the warehouse body to connect the cleaning platforms 7 on each floor.

[0041] The collecting hopper 11 is provided with a hopper body, a cover plate is provided on the top of the hopper body, an inspection port 24 is provided in the center of the cover plate, a plurality of feed holes 23 are provided on the cover plate around the inspection port 24, the feed holes 23 are evenly arranged along the circumference of the inspection port 24, and a discharge port is provided at the bottom of the hopper body. The collecting hopper is evenly connected to the discharge chute on a concentric circle, and the rice is used to form an overall flow in the discharge chute 10.

[0042] A high level sensor 16, a middle level sensor 15 and a low level sensor 13 are installed in the silo body to feedback the rice level. The high level sensor 16, the middle level sensor 15 and the low level sensor 13 are arranged in sequence from top to bottom. The high level sensor 16, the middle level sensor 15 and the low level sensor 13 are connected to the flow regulating gate 12 through the controller. The flow regulating gate 12 can use a manual gate to control the discharge flow rate, or it can cooperate with a pneumatic gate to realize the remote switch function. The high level sensor is installed on the upper part of the silo body 6 to feedback the rice level. When the reaction level reaches the maximum limit, it is necessary to reduce the feed flow or shut down the feed; the middle level sensor is installed in the middle part of the silo body 6 to feedback the rice level and reflect that the level reaches a certain height; the low level sensor is installed at the bottom of the silo body 6 to feedback the rice level and reflect that the level is low.

[0043] The working principle of the continuous unpowered rice cooler of the utility model is:

[0044] Before the rice with a higher temperature enters the equipment, the adjustable flow gate 12 for discharging is in a closed state; it is evenly distributed to the feed box 3 through the feed chute 2 after passing through the uniform distributor 1; it enters the silo 6 after the gravity door inside the feed box 3 is closed, and is connected to the buffer 5 for feeding; it flows through the buffer 5 to the silo bottom receiving hopper 9, the discharging chute 10, and the collecting hopper 11 to reach the adjustable flow gate 12 for discharging. Since the adjustable flow gate 12 for discharging is in a closed state, the rice begins to accumulate in the reverse direction upward; when the rice accumulates to the middle material level sensor 16, the damper (or fan) connected to the air suction port is opened, and the adjustable flow gate 12 for discharging is opened at this time, and the flow is manually adjusted so that the rice is processed between the middle material level sensor 16 and the high material level sensor 18; the room temperature air enters the silo 6 from the air inlet and anti-arching component 8, passes through the rice layer from bottom to top, and is finally sucked into the external air network system from the air suction port 4. The external air network system needs to provide sufficient air pressure and air volume; after the rice is processed between the middle material level sensor 15 and the high material level sensor 16, the rice enters and exits at the same time.

[0045] The automatic control process of the continuous unpowered rice cooler of the utility model is as follows:

[0046] When the discharge adjustable flow gate 12 is opened properly, the inlet and outlet amounts are the same, the material level is balanced, and rice is discharged while entering.

[0047] When the adjustable flow gate 12 of the material discharge is opened too much, the material discharge is greater than the material feed, and the material level is lower than the middle material level sensor 15, the adjustable flow gate 12 of the material discharge and the air suction can be controlled to be closed to prevent the rice from bursting due to too little rice, thin material layer, insufficient cooling time, and too fast cooling.

[0048] When the adjustable discharge flow gate 12 is opened too small, the discharge amount is less than the feed amount, and the material level finally reaches the high material level sensor 16. At this time, it is necessary to adjust the feed or discharge flow to ensure the balance of material flow. If the high material level sensor 16 lasts for a period of time, it is necessary to close the front material to prevent upward blockage.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
