Description

Technical Field

[0001] This utility model relates to the field of vegetable processing technology, specifically to a bubble cleaning device. Background Technology

[0002] In the field of natural pigment extraction, tuber crops such as potatoes and sweet potatoes are the core raw materials for preparing high-quality natural pigments such as carotenoids and anthocyanins. The content of natural pigment components in the epidermis and internal tissues of these raw materials is stable and easy to extract through physical or chemical methods, making them a key source in the natural pigment supply chain for the food, pharmaceutical, and cosmetic industries.

[0003] In the pretreatment process of tuber raw materials, surface cleanliness control is the core link that determines the efficiency of subsequent processes and product quality: after the raw materials are harvested, a large amount of mud and sand are easily attached to the surface. If the cleaning is not thorough, these mud and sand impurities will not only contaminate the pigment extract in the subsequent crushing and extraction process, but may also clog the extraction equipment.

[0004] Currently, bubble cleaning devices are commonly used for surface cleaning of potatoes, sweet potatoes, etc. However, traditional tuber cleaning machines mostly adopt a one-way water rinsing mode, that is, the cleaning water is continuously injected into the cleaning tank from an external water source, and after one bubble disturbance or spray, it is discharged into the wastewater system with impurities. There is no water purification and recycling structure, which leads to waste of water resources.

[0005] Therefore, solving the above-mentioned technical problems has become a key issue that urgently needs to be addressed in the current field of vegetable processing technology.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0025] See Figures 1-4 To address the problems mentioned in the background section, this utility model provides a bubble cleaning device to solve the aforementioned technical problems. The technical solution is as follows:

[0026] A bubble cleaning device includes: a support 110, a cleaning tank 120, a bubble generating unit, an orifice plate 140, a spray washing unit, a filter box 171, and a water pump 181.

[0029] The bubble generating unit includes a vortex blower 130 fixed on a bracket 110, multiple air supply pipes 132 spaced apart on the wall of the cleaning tank 120, and a main air pipe 131 connected to the multiple air supply pipes 132. The other side of the main air pipe 131 is connected to the air outlet of the vortex blower 130. The air outlets of the multiple air supply pipes 132 are located below the orifice plate 140.

[0030] The filter box 171 is fixed on one side wall of the cleaning tank 120, and a number of filter holes 123 are provided on the wall of the cleaning tank 120 that is in contact with the filter box 171.

[0031] The spray washing unit includes multiple spray heads 151 spaced apart on the wall of the washing tank 120, and a first water supply pipe 152 connected to the tail of the multiple spray heads 151. The first water supply pipe 152 is connected to the outlet of a water pump 181 fixed on a bracket 110. The inlet of the water pump 181 is connected to a filter box 171 through a pipe 182.

[0032] In this embodiment, multiple filter plates 172 are vertically spaced in the filter box 171; the number of filter plates 172 and the size of their filter holes are set according to the actual situation.

[0033] In this embodiment, a conveyor belt 160 is provided on the tank wall opposite to the spray head 151 of the cleaning tank 120; a secondary cleaning unit is provided on the fixed frame of the conveyor belt 160.

[0034] The secondary cleaning unit includes a side plate 162 fixed on the conveyor belt 160 frame, a plurality of cleaning pipes 161 fixed at intervals on the side plate 162, and a second water supply pipe 163 connected to the plurality of cleaning pipes 161.

[0035] The bottom surface of the cleaning pipe 161 is provided with several spray holes; the other end of the second water supply pipe 163 is connected to the outlet of the water pump 181.

[0036] It should be noted that the first water supply pipe 152 and the second water supply pipe 163 are connected to the outlet of the water pump 181 through a tee connector; and each of the first water supply pipe 152 and the second water supply pipe 163 is equipped with an independent control valve.

[0037] In this embodiment, a number of spray holes at the bottom of the cleaning pipe 161 are arranged at equal intervals along the length of the cleaning pipe 161, and the diameter of the spray holes is 1-3mm.

[0038] It should be noted that after the tuber raw materials are cleaned in the cleaning tank 120, the conveyor belt 160 can be controlled to transfer the tuber raw materials in the cleaning tank 120 to the outside; at the same time, the water pump 181 supplies water to multiple cleaning pipes 161 of the secondary cleaning unit through the second water supply pipe 163 (sharing the same water source with the spray washing unit to achieve water recycling and reuse), and the spray holes at the bottom of the cleaning pipe 161 spray clean water flow onto the raw materials on the conveyor belt 160 to rinse the trace impurities that may remain on the surface of the raw materials again, thereby improving product quality.

[0039] In this embodiment, a return water collection cover is provided at the bottom of the conveyor belt 160. The lower end of the return water collection cover is connected to the wall of the cleaning tank 120 through a pipe or directly, so that the collected return water can flow back into the cleaning tank 120, further realizing the recycling of cleaning water and reducing water overflow and waste.

[0040] The method of using the bubble cleaning device provided in this embodiment of the utility model is as follows:

[0041] Step 1, device pretreatment and initial water supply: Inject clean water into the washing tank 120 until the water level overflows the perforated plate 140 (the water level should be sufficient to completely submerge the tuber raw material to be washed); close the control valve 122 on the drain pipe 121 to ensure that the water in the washing tank 120 is sealed; at the same time, check whether the multiple vertically spaced filter plates 172 in the filter box 171 are installed in place to ensure that the filter channel is unobstructed.

[0042] Step 2, Raw material loading and bubble cleaning start-up: The tuber raw materials such as potatoes and sweet potatoes to be cleaned are laid flat on the perforated plate 140 in the cleaning tank 120; the vortex fan 130 of the bubble generating unit is started. The airflow generated by the vortex fan 130 is split into multiple air supply pipes 132 arranged at intervals through the main air pipe 131, and finally released from the air outlet of the air supply pipe 132 located below the perforated plate 140; after the airflow passes through the perforated plate 140, it forms dense microbubbles in the water in the cleaning tank 120. As the microbubbles rise, they disturb the water and impact the surface of the tuber raw materials on the perforated plate 140, peeling off the attached mud and other impurities.

[0043] Step 3, Spray washing unit linkage and water circulation filtration: Start water pump 181, water pump 181 draws water from filter box 171 through pipe 182 connected to the water inlet; at this time, water in washing tank 120 flows into filter box 171 through several filter holes 123 on the tank wall, and forms clean circulating water through multiple filter plates 172 in the tank; water pump 181 pressurizes the filtered clean water and delivers it to the first water supply pipe 152, and then sprays it out through multiple spray heads 151 set at intervals on the tank wall of washing tank 120; the sprayed water acts on the surface of tuber raw material in the form of high pressure spray, and performs secondary stripping of the fine impurities remaining after bubble washing, realizing the dual cleaning of "bubble disturbance + high pressure spray", and the water in washing tank 120 is reused throughout the process, without the need to introduce external new water.

[0044] It should be noted that when the amount of impurities deposited at the bottom of the cleaning tank 120 reaches a certain level, the orifice plate 140 can be removed, the cleaning tank 120 can be flushed with high-pressure water, and the control valve 122 on the drain pipe 121 can be opened, so that the deposited mud and other impurities are discharged from the drain pipe 121 along with a small amount of water.
