DETAILED DESCRIPTION

[0025] The technical solutions in the utility model will be further described below in combination with the drawings and examples.

[0026] Example 1

[0027] Please refer to Figs. 1-3 A multi-stage melon seed cleaning device is shown, which includes a feed tank 1, a soaking tank 2, an ultrasonic cleaning tank 3, a drum screen 4 and a first mesh belt conveyor 5. The specific implementation is as follows:

[0028] Feed tank 1: The top is provided with a feed hopper 11 for receiving melon seed raw materials to be cleaned. An inclined downward second mesh belt conveyor 6 is installed inside, and a high-pressure spray device 7 is provided above, for preliminary removal of larger impurities and soil. When the melon seeds enter the feed tank 1, they are sent to the soaking tank 2 via the second mesh belt conveyor 6.

[0029] Soaking tank 2: It is in communication with the feed tank 1 and is used to soak the melon seed raw materials coming out of the feed tank 1 to soften the surface attachments. A first overflow port 21 is provided downstream of the soaking tank 2 for guiding the soaked melon seeds to the ultrasonic cleaning tank 3.

[0030] Ultrasonic cleaning tank 3: An ultrasonic generator 31 is installed at the bottom to generate high-frequency vibrations, causing countless micro-bubbles to form in the water. The impact force generated when these bubbles burst can effectively remove residues on the surface of the melon seeds. A second overflow port 32 is provided downstream of the ultrasonic cleaning tank 3 for guiding the cleaned melon seeds to the drum screen 4.

[0031] Drum screen 4: It is installed downstream of the ultrasonic cleaning tank 3 and is used to separate the cleaned melon seeds and waste water. The design of the drum screen 4 allows the melon seeds to pass through while the waste water is blocked, thereby achieving solid-liquid separation.

[0032] First mesh belt conveyor 5: It is located below the drum screen 4 and is used to receive the melon seeds falling from the drum screen 4 and convey them to the next process, such as drying or packaging.

[0033] Example 2

[0034] On the basis of example 1, the structure and function of the cleaning device are further optimized:

[0035] The bubble generator 8 is installed on the side wall of the cleaning tank 3, and the generated bubbles move towards the downstream of the cleaning tank 3. The impact force generated by the breaking of the bubbles helps to remove the residues on the surface of the melon seeds, and the cleaning effect is enhanced.

[0036] The rotator 9 is arranged in parallel in the cleaning tank 3, and the push plate is fixedly connected to the rotating shaft of each rotator 9. The push plate is driven to rotate by the motor, and the melon seeds are pushed to move towards the downstream of the cleaning tank 3, so as to ensure the residence time of the melon seeds in the cleaning tank 3 and the cleaning effect.

[0037] The guide plate 33 is arranged at the downstream of the cleaning tank 3, and is used to guide the water in the cleaning tank 3 to the second overflow port 32, so as to guide the melon seeds cleaned in the cleaning tank 3 to the second overflow port 32 along with the water flow.

[0038] The guide plate 22 is fixedly connected to the first overflow port 21 of the soaking tank 2 and is inclined downward, and is used to smoothly guide the melon seeds under water to the cleaning tank 3, so as to avoid the accumulation or blockage of the melon seeds.

[0039] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
