[0002] In the specialty oils and fats industry of the food industry, solid fat content (SFC) is one of the most important control indicators. Testing this indicator requires nuclear magnetic resonance (NMR) tubes, and these tubes are used in large quantities. Normally, after testing the solid fat content of specialty oils and fats using NMR tubes, the tubes need to be thoroughly cleaned to ensure reuse.

[0003] Existing methods for cleaning NMR tubes mainly fall into two categories: brushing and boiling.

[0004] The brushing method usually involves manually inserting a special fine-bristled brush into the cavity of the NMR tube to clean it. However, this method can only clean one NMR tube at a time, which is labor-intensive and inefficient for workers.

[0005] The boiling and washing method typically involves placing multiple NMR tubes into a washing tank, adding an appropriate amount of water, and then heating the water in the washing tank to melt the grease inside the NMR tubes. Finally, the boiled and washed NMR tubes are removed, achieving batch cleaning of multiple NMR tubes. However, this boiling and washing method can easily leave grease residue on the inner and outer walls of the NMR tubes, affecting the accuracy of subsequent tests. Utility Model Content

[0033] Reference Figure 1 An example of this utility model provides a nuclear magnetic resonance tube cleaning device, which includes a boiling and washing mechanism 100, a waste oil collection mechanism 200, a brushing mechanism 300, and a rinsing mechanism 400.

[0034] Functionally, the boiling and washing mechanism 100 is used to boil and wash the NMR tube, the waste oil collection mechanism 200 is used to collect the waste oil after boiling and washing, the brushing mechanism 300 is used to brush and wash the inner cavity of the NMR tube, and the rinsing mechanism 400 is used to rinse the inner cavity of the NMR tube.

[0035] Structurally, the washing mechanism 100 includes a washing tub 110 and a fixing frame 120 disposed inside the washing tub 110. The fixing frame 120 has multiple clamping parts for clamping vertically placed nuclear magnetic resonance tubes. A water discharge switch 115 is disposed on the lower side of the washing tub 110.

[0036] Furthermore, the waste oil collection mechanism 200 includes a waste oil collection tank 210 and an opening and closing component 220 connected to the waste oil collection tank 210. The bottom of the waste oil collection tank 210 is provided with a plurality of first through holes 211. The opening and closing component 220 is used to open or close the plurality of first through holes 211. The waste oil collection tank 210 is detachably connected to the washing tank 110.

[0037] Furthermore, the washing mechanism 300 includes an auxiliary positioning frame 310 and a scrubbing device 320 detachably connected to the auxiliary positioning frame 310. The scrubbing device 320 includes a support plate 321, a plurality of brushes 322 rotatably connected to the support plate 321, and a drive assembly 323 for driving the plurality of brushes 322 to rotate. The auxiliary positioning frame 310 is detachably connected to the top of the washing tub 110. The axes of the brushes 322 are arranged in a vertical direction, and the plurality of brushes 322 correspond one-to-one with the plurality of nuclear magnetic resonance tubes.

[0038] Furthermore, the rinsing mechanism 400 includes a rinsing device 410, an injection pipe 420 disposed on the top of the rinsing device 410, and a plurality of rinsing pipes 430 disposed on the bottom of the rinsing device 410. The rinsing device 410 is provided with an inner cavity, and the injection pipe 420 and the plurality of rinsing pipes 430 are all in communication with the inner cavity. The rinsing device 410 is detachably connected to the auxiliary positioning frame 310.

[0039] The cleaning process is divided into three stages: boiling to remove oil, brushing, and rinsing.

[0040] Boiling and degreasing stage: Multiple NMR tubes are vertically placed on multiple clamping parts of the fixing frame 120, with the openings of the NMR tubes facing upwards for easy clamping and fixing. Next, the fixing frame 120 is placed into the boiling and washing tank 110, and water is injected into the tank to immerse the NMR tubes. Then, the waste oil collection tank 210 is connected to the boiling and washing tank 110. At this time, the opening and closing component 220 opens several first through holes 211 on the waste oil collection tank 210. Water is continuously injected into the washing tank 110 until it covers the bottom wall of the waste oil collection tank 210. By heating the water in the washing tank 110, the grease in the multiple NMR tubes is melted. The melted grease floats to the surface of the water through the first through hole 211 and enters the waste oil collection tank 210. Then, the opening and closing component 220 closes several of the first through holes 211 to ensure that the liquid in the waste oil collection tank 210 cannot flow into the washing tank 110. Finally, the waste oil collection tank 210 is removed, thereby realizing the collection of waste oil.

[0041] Washing stage: Add an appropriate amount of detergent to the washing tub 110 to mix the detergent with the water in the washing tub 110, and continue to heat the liquid in the washing tub 110. Under heating, the viscosity of residual grease decreases, and the surfactant molecules in the detergent have a solubilizing and emulsifying effect, causing the residual grease to disperse in the water and mix with the liquid in the washing tub 110 to form an emulsion. Then, install the auxiliary positioning frame 310 and the scrubbing device 320 in sequence, so that multiple brushes 322 in the scrubbing device 320 extend into the inner cavity of multiple NMR tubes. Then, the drive assembly 323 drives multiple brushes 322 to rotate simultaneously, and the multiple brushes 322 clean the inner cavity of multiple NMR tubes respectively. Finally, remove the scrubbing device 320 and open the drain valve 115 to drain the liquid in the washing tub 110.

[0042] Rinsing stage: The rinsing device 410 is installed on the auxiliary positioning frame 310, so that the multiple rinsing tubes 430 on the rinsing device 410 are inserted into the multiple NMR tubes respectively. Then, clean high-pressure water is connected to the injection tube 420. The high-pressure water is sprayed out from the multiple rinsing tubes 430 and rinses the inner cavity of the NMR tubes. Then, the high-pressure water is removed, and a high-pressure gas source is connected to the injection tube 420. The high-pressure gas is sprayed out from the multiple rinsing tubes 430 and blows dry or blows out the water in the inner cavity of the NMR tubes. Finally, the rinsing device 410 is removed and the multiple NMR tubes are taken out.

[0043] Therefore, this invention can simultaneously perform batch cleaning of multiple NMR tubes, reducing the labor intensity of workers, improving work efficiency, and also reducing the amount of grease remaining on the inner wall of the NMR tubes, thus improving the cleanliness of the NMR tubes.

[0044] In some preferred embodiments, the opening and closing assembly 220 includes a rotating plate 221 and a rotating rod 222 disposed on the rotating plate 221. The rotating plate 221 has a plurality of second through holes 223. When the rotating rod 222 is rotated, the rotating rod 222 drives the rotating plate 221 to rotate. The plurality of second through holes 223 on the rotating plate 221 correspond one-to-one with or are misaligned with a plurality of first through holes 211, so as to realize the opening or closing of the first through holes 211. Thus, it is convenient for a plurality of first through holes 211 to be opened or closed at the same time, thereby improving working efficiency.

[0045] In some preferred embodiments, the inner wall of the washing tank 110 is provided with an inner boss 111, and the bottom of the waste oil collection tank 210 is provided with an outer boss 212. The inner boss 111 is used to support the outer boss 212, thereby facilitating the placement and removal of the waste oil collection tank 210 and improving assembly efficiency.

[0046] Furthermore, the outer periphery of the washing tank 110 is provided with two clips 112, which are used to press the outer boss 212 onto the inner boss 111, thereby preventing the waste oil collection tank 210 from shifting or detaching during the washing process and ensuring the stability of the equipment.

[0047] In some preferred embodiments, the mounting bracket 120 has an upper plate 121, a middle plate 122 and a lower plate 123 arranged in parallel. The upper plate 121 and the middle plate 122 are each provided with a plurality of corresponding third through holes 124. The third through holes 124 are provided with elastic washers. The elastic washers are used to fit around the outer periphery of the NMR tube. The lower plate 123 is used to support the bottom of the NMR tube.

[0048] It is understandable that by passing the NMR tubes sequentially through the third through-hole 124 of the upper plate 121 and the middle plate 122 until the bottom of the NMR tube abuts against the lower plate 123, the height of the multiple NMR tubes can be kept consistent, while keeping the NMR tubes vertically positioned.

[0049] By setting an elastic washer in the third through hole 124, the NMR tube can be clamped and fixed, thereby ensuring that the NMR tube will not rotate during the brushing process and ensuring effective brushing.

[0050] Furthermore, the outer side of the fixing frame 120 is provided with a movable handle, thereby facilitating the removal or placement of the fixing frame 120 into the washing tub 110.

[0051] In some preferred embodiments, the drive assembly 323 includes a rocker arm 3231, a drive gear 3232, a plurality of inter-row gears 3233, and a plurality of driven gears 3234. The rocker arm 3231 is rotatably connected to the middle of the support plate 321. The drive gear 3232 is mounted on the bottom of the rocker arm 3231. The inter-row gears 3233 are rotatably connected to the bottom of the support plate 321 via a rotating shaft. The driven gears 3234 are mounted on the brush 322. The inter-row gears 3233 are located between the drive gear 3232 and the driven gears 3234. The drive gear 3232 meshes with the inter-row gears 3233, and the inter-row gears 3233 mesh with the driven gears 3234.

[0052] Understandably, by shaking the rocker arm 3231, the rocker arm 3231 drives the drive gear 3232 to rotate, the drive gear 3232 simultaneously drives several inter-row gears 3233 to rotate, the several inter-row gears 3233 drive several driven gears 3234 to rotate, and in turn drive several brushes 322 to rotate. Thus, multiple brushes 322 can simultaneously brush the inner cavity of multiple NMR tubes, improving work efficiency.

[0053] In some preferred embodiments, the bottom wall of the washing tub 110 is provided with a first positioning protrusion 113, the bottom of the fixing frame 120 is provided with a first notch 125, the first positioning protrusion 113 and the first notch 125 cooperate, the top of the washing tub 110 is provided with a second positioning protrusion 114, the bottom of the auxiliary positioning frame 310 is provided with a second notch 311, the second positioning protrusion 114 and the second notch 311 cooperate.

[0054] Furthermore, the top of the auxiliary positioning frame 310 is provided with a positioning groove 312, and the outer periphery of the support plate 321 is provided with a first positioning handle 324, which cooperates with the positioning groove 312.

[0055] Understandably, when the fixing frame 120 is placed inside the washing tub 110, the first notch 125 on the fixing frame 120 is engaged with the first positioning protrusion 113, which can achieve the positioning of the fixing frame 120 and make the multiple NMR tubes on the fixing frame 120 located in a fixed position. When the auxiliary positioning frame 310 is installed on the top of the washing tub 110, the second notch 311 on the auxiliary positioning frame 310 is engaged with the second positioning protrusion 114, which can achieve the positioning of the auxiliary positioning frame 310. By placing the first positioning handle 324 on the positioning groove 312, it is convenient to install and remove the scrubber 320. At the same time, the support plate 321 can be positioned to ensure that the multiple brushes 322 on the support plate 321 correspond one-to-one with the multiple NMR tubes on the fixing frame 120, thereby ensuring the precise matching of the brushes 322 and the NMR tubes.

[0056] Furthermore, the rinsing device 410 is provided with a second positioning handle 411 on its exterior. The second positioning handle 411 cooperates with the positioning groove 312, thereby facilitating the installation and removal of the rinsing device 410. At the same time, it can achieve precise positioning of the rinsing device 410, ensuring that the multiple rinsing tubes 430 in the rinsing device 410 correspond one-to-one with the multiple NMR tubes on the fixing frame 120, and ensuring precise cooperation between the rinsing tubes 430 and the NMR tubes.

[0057] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments.
