Description

Technical Field

[0001] The utility model relates to the technical field of edible oil filling, in particular to a reflux device for edible oil filling. Background Art

[0002] Edible oil is mostly vegetable oil. In order to facilitate later transportation, the edible oil will be filled into oil barrels in a fixed amount, and then the edible oil in the oil barrels will be transferred to transport bottles for transportation.

[0003] When filling edible oil, the edible oil in the oil tank is transported to the oil barrel through the oil inlet pipe. When a certain amount of edible oil is transported, the oil inlet pipe is immediately closed, and the remaining edible oil in the oil inlet pipe will still enter the oil barrel through the oil inlet pipe. This causes the liquid level of the edible oil to be higher than the warning line. The oil barrel cannot collect the overflowed edible oil, resulting in overflow of the edible oil when it is transported to the transport bottle. The overflowed edible oil will be directly discharged instead of flowing back into the oil tank, thereby causing consumption of edible oil resources and filling efficiency. Summary of the Invention

[0004] The utility model aims to solve the problem in the prior art that oil barrels cannot collect overflowed edible oil, and proposes a reflux device for edible oil filling.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-Figure 3A reflux device for filling edible oil includes a base 1 and a bracket 2 connected as one body. The base 1 is provided with an oil barrel 3. The bracket 2 is fixedly mounted with an oil tank 4. The oil tank 4 is provided with an oil inlet pipe 5 extending into the oil barrel 3. The oil inlet pipe 5 is provided with a valve body 6. The base 1 is provided with a liquid level plate 18. A ring frame 22 for guiding the oil barrel 3 is fixedly mounted on the base 1. The liquid level plate 18 can monitor the edible oil level in the oil barrel 3. The ring frame 22 can guide the oil barrel 3.

[0021] The bracket 2 is fixedly mounted with a matching receiver 7 and a controller 8, and the base 1 is mounted with a support 10 and an alarm 9 electrically connected to the controller 8. The support 10 is fixedly mounted with a pressure sensor 11 that is movable against the oil barrel 3.

[0022] Four circumferentially distributed guide rods 12 are fixedly installed in the base 1, and a slider 13 is slidably sleeved on the guide rod 12. The support 10 is vertically arranged below the oil drum 3, and the guide rod 12 is arranged horizontally. A connecting rod 15 is connected between the slider 13 and the oil drum 3. The guide rod 12 guides the slider 13 so that the slider 13 can smoothly pull the connecting rod 15 when moving.

[0023] A spring 14 is welded between the slider 13 and the base 1. The spring 14 is welded horizontally, and the two ends of the connecting rod 15 are pin-connected to the slider 13 and the oil barrel 3 respectively. When the oil barrel 3 collects the cooking oil, its own gravity increases, and the oil barrel 3 continues to move downward and exerts pressure on the pressure sensor 11 below. It should be noted that when the oil barrel 3 exerts pressure on the pressure sensor 11, it means that the cooking oil in the oil barrel 3 has reached the specified weight. After the pressure sensor 11 is pressurized, it transmits a signal to the receiver 7. The receiver 7 immediately sends an instruction to the controller 8, causing the controller 8 to immediately turn on the alarm 9. The warning sound or warning light emitted by the alarm 9 can alert the operator;

[0024] A through hole 16 is provided in the oil barrel 3. A collection frame 19 for collecting overflowed cooking oil is fixedly installed on the oil barrel 3. A collection pump 17 corresponding to the collection frame 19 is provided on the oil barrel 3. A return pipe 20 is connected between the collection frame 19 and the oil tank 4. A valve body 21 is provided on the return pipe 20. The return pipe 20 is a hose and a one-way valve for controlling the flow direction is provided in the return pipe 20. The one-way valve can control the flow direction of the cooking oil and prevent the cooking oil in the oil tank 4 from entering the oil barrel 3 through the return pipe 20.

[0025] In addition, the edible oil level in the oil barrel 3 cannot be higher than the through hole 16. If the edible oil level exceeds the height of the through hole 16, it means that the edible oil level is higher than the specified level. At this time, the excess edible oil enters the collection frame 19 through the through hole 16 and is recovered into the oil tank 4 by the collection pump 17.

[0026] It should be noted that the specific models and specifications of the valve body 6, receiver 7, controller 8, alarm 9, pressure sensor 11, collection pump 17, and one-way valve need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0027] The functional principle of this utility model can be explained through the following operation modes:

[0028] The controller 8 sends a command to the valve body 6, so that the cooking oil in the oil tank 4 enters the oil barrel 3 through the oil inlet pipe 5;

[0029] As the edible oil is continuously delivered, the weight of the oil barrel 3 increases. The pressure generated by the weight of the oil barrel 3 applies pressure to the connecting rod 15 below, causing the connecting rod 15 to pull the slider 13 when it moves downward. The slider 13 is pulled by the connecting rod 15 and slides toward the outside of the guide rod 12. The spring 14 is stressed, causing the oil barrel 3 to slowly move downward in the ring frame 22 and disconnect from the oil inlet pipe 5.

[0030] When the weight of the oil drum 3 reaches a specified value, the bottom of the oil drum 3 will apply pressure to the pressure sensor 11 below. After the pressure is applied, the pressure sensor 11 immediately sends a signal to the receiver 7, and the receiver 7 immediately sends a signal to the controller 8, so that the receiver 7 immediately turns on the alarm 9 to warn the surrounding operators.

[0031] At the same time, the controller 8 immediately sends a closing command to the valve body 6 to stop delivering the cooking oil, and the remaining cooking oil in the oil inlet pipe 5 falls into the oil barrel 3;

[0032] The controller 8 sends a command to the collection pump 17 to pump the excess cooking oil in the oil barrel 3 into the collection frame 19, so that the liquid level of the cooking oil in the oil tank 4 is lower than the height of the through hole 16;

[0033] When excess cooking oil enters the collection frame 19, the controller 8 sends a command to the second valve body 21, so that the cooking oil in the collection frame 19 flows back to the oil tank 4 through the return pipe 20;

[0034] When the cooking oil in the oil barrel 3 is completely drained, the height of the oil barrel 3 is slowly raised to a specified height, and the height change of the oil barrel 3 can be observed through the liquid level plate 18 .

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
