Therefore, it can be understood that, according to the technical solution of the present invention, the cleaning and drying device 100 cleans the material through the cleaning mechanism 10 along the conveying direction of the conveying track 30, and dries the material through the infrared drying chamber 21 in an infrared drying manner after the cleaning is completed, so as to avoid that the raised dust caused by air convection and the metal particles caused by equipment abrasion are attached to the surface of the product when the fan is used for drying, thereby affecting the quality of the product. That is, the technical solution of the present invention provides a novel cleaning and drying device 100, which reduces the particles in the drying environment to prevent the particles from affecting the quality of the product.
Naturally, in other embodiments of the present invention, other static drying manners may also be used to perform drying processing on the product, for example, high temperature drying, ultraviolet drying, and the like, and similarly, other static drying manners may also be used to avoid that the raised dust caused by air convection and the metal particles caused by equipment abrasion are attached to the surface of the product when the fan is used for drying, so as to affect the quality of the product.
Referring to fig. 1 and fig. 2, in an embodiment of the cleaning and drying apparatus 100 of the present invention, the conveying track 30 includes a plurality of conveying rollers 31, and the plurality of conveying rollers 31 are spaced side by side along a conveying direction of the conveying track 30 to form the conveying track 30.
In this embodiment, the two ends of the plurality of transmission rollers 31 are both connected with a connection belt in a transmission manner. The nozzles of the spray booth 11 are disposed above or below the transfer rail 30 and on the gap between each transfer roller 31 and the adjacent transfer roller 31 such that the water outlet direction of the nozzles of the spray booth 11 passes through the gap to clean the product.
It will be appreciated that in order to enhance the cleaning effect of the cleaning mechanism 10 on the products to perform overall cleaning of the products conveyed on the conveying track 30, the conveying track 30 is formed by a plurality of conveying rollers 31 spaced side by side to sufficiently clean the products while being conveyed to the gaps between the conveying rollers 31.
Referring to fig. 1, in an embodiment of the cleaning and drying device 100 of the present invention, the cleaning mechanism 10 includes a spraying chamber 11, an ultrasonic washing chamber 12, and an overflow washing chamber 13, which are disposed at intervals, the infrared drying mechanism 20 includes an infrared drying chamber 21, and the conveying track 30 sequentially penetrates through the spraying chamber 11, the ultrasonic washing chamber 12, the overflow washing chamber 13, and the infrared drying chamber 21 along a conveying direction of the conveying track 30, so that the products on the conveying track 30 sequentially flow through the spraying chamber 11, the ultrasonic washing chamber 12, the overflow washing chamber 13, and the infrared drying chamber 21.
In this embodiment, at least two spray rooms 11 may be provided, so that when the product is insufficiently cleaned when passing through the first spray room 11, the next spray room 11 may be used to perform spray cleaning again, thereby improving the cleaning effect on the product. The product enters the spray chamber 11 for cleaning, and large particles on the surface of the product are cleaned mainly in a high-pressure water cleaning mode, and the cleaned sewage is discharged from a water outlet of the spray chamber 11.
The working principle of the product entering the ultrasonic water washing chamber 12 is approximately that the sound energy of the power ultrasonic frequency source is converted into mechanical vibration through the transducer in the ultrasonic water washing chamber 12, and the ultrasonic waves are radiated to the cleaning liquid in the water washing tank 121 through the water washing tank 121. Due to the radiation of the ultrasonic wave, micro bubbles in the liquid in the washing tank 121 can keep vibrating under the action of the sound wave, the adsorption of dirt and the surface of a cleaning piece is damaged, the dirt layer is damaged by fatigue and is separated, the vibration of the gas bubbles cleans the solid surface, the welding flux on the surface of the product is cleaned, and the cleaned sewage is discharged from a water outlet of the ultrasonic washing chamber 12.
The overflow washing chamber 13 mainly immerses all the products in the washing liquid, the circulating water in the overflow tank continuously circulates to further clean the raised dust or micro particles on the surfaces of the products, and the cleaned sewage is discharged from the water outlet of the overflow washing chamber 13.
The working principle of the product entering the infrared drying chamber 21 is approximate, and the molecule of the substance can completely convert the energy of the photon into the vibration of the molecule, namely the rotation energy after absorbing the infrared energy; the rotational energy of the molecule can also be changed. Moreover, the vibration spectrum has the effect of widening vibration and rotation, and can enlarge the amplitude with the balance position as the center and intensify the vibration in the vibration spectrum. Since the movement of electrons and the vibration of molecules are at extremely high speeds, the movement constantly causes the vibration of crystal lattices and bond groups to collide with each other. The change of the motion state is as if the friction of two fast-running objects is accelerated to heat and raise the temperature, so the temperature rise speed is high. Meanwhile, when the article is heated by infrared radiation, the temperature of the article is often higher than the surface of the article according to the part through which the infrared radiation can penetrate. For example, the internal temperature of the corn kernels after infrared radiation is measured to be 5-10 ℃ higher than the surface temperature. Therefore, the products heated by infrared radiation in the dehydration drying are in the simultaneous action of high-inside and low-outside temperature gradient and humidity gradient, and the moisture in the products is continuously transferred out and diffused and evaporated, thereby achieving the purpose of rapid drying.
The spray chamber 11, the ultrasonic washing chamber 12, the overflow washing chamber 13 and the infrared drying chamber 21 can all control one or all of the mechanisms to work through control switches.
