Description

Technical Field

[0001] The utility model relates to the field of gutter oil detection, and particularly relates to a gutter oil detection device based on nanomaterials. Background Art

[0002] Gutter oil is generally oil processed from leftovers through a certain process (usually repeated use). At present, there is no unified national standard for its detection. However, compared with normal edible oil commonly used by people, gutter oil has a higher acidity, and acid value is the most basic parameter for measuring the quality of oil; acid value refers to the amount of KOH that can be neutralized by the acidic substances produced by the corruption of 1g of oil. If the acid value exceeds 4.0, it is gutter oil or recycled oil. Therefore, an edible oil acid value detection card is often used for detection.

[0003] However, currently people often use a straw to suck the oil to be detected, and then drop the oil onto the oleic acid value detection card (i.e., reagent). In this process: (1) Most of the sucked oil is an oil-water mixture, and its concentration will affect the detection accuracy of the acidity of the oleic acid value; (2) During the transfer process, since the force of the human hand holding the straw will change, the oil often accidentally drips, affecting the hygiene of the experimental platform; (3) Most straws are disposable straws, or the materials used are adhered to the oil and are not easy to clean; (4) High-end detection devices have a high cost and are inconvenient to carry, and cannot be applied to the working scenarios of market supervision and management staff.

[0004] Therefore, there is an urgent need for a gutter oil detection device with low cost, simple detection process, easy to clean and thus reusable. Content of the Utility Model

[0005] In order to make up for the deficiencies in the prior art and achieve the above functions, the utility model provides a gutter oil detection device based on nanomaterials.

[0006] The utility model is realized by the following technical solutions:

[0007] A gutter oil detection device based on nanomaterials includes a suction tube barrel and a suction tube plug. The suction tube barrel includes a conical barrel head at the front end of the barrel body, and a suction port is arranged in front of the barrel head. The suction tube plug is installed in the barrel body of the suction tube barrel. A set of symmetric detection mechanisms are arranged on both sides of the barrel body. The main body of the detection mechanism is an "L"-shaped oil suction channel, and an "L"-shaped hydrophobic sponge is installed in the oil suction channel. The hydrophobic sponge is soaked with a nano-coating and can only absorb oil and is difficult to absorb water.

[0008] The oil suction channel is made of a transparent material, and its side is rotatably connected to a sealing cover through a micro hinge, and a button is arranged on the sealing cover.

[0009] Furthermore, the hydrophobic sponge is located outside the inner wall of the cylinder and fits against the inner wall of the oil suction channel. A filter and a detection card are also installed in the oil suction channel. The filter is abutted against the rear end face of the hydrophobic sponge, and the detection card is engaged in the gap between the filter and the rear end face of the oil suction channel.

[0010] Furthermore, a portion of the sealing cover in contact with the oil suction channel is provided with an annular recessed groove, a rubber ring is installed in the recessed groove, and the sealing cover and the oil suction channel are locked by a buckle.

[0011] Furthermore, the button is in the shape of an "I" character, including an arc-shaped top cover located outside the sealing cover, a support column and an extrusion cover located inside; the support column is installed in the circular groove through hole of the sealing cover and the two ends are respectively connected to the top cover and the extrusion cover, and a spring is sleeved on the support column and the spring is located outside the sealing cover.

[0012] Furthermore, a leak-proof ring is provided between the circular groove of the extrusion cover and the sealing cover, and the inner side of the leak-proof ring abuts against the support column.

[0013] Furthermore, the extrusion cover is directly opposite to the side of the "L"-shaped hydrophobic sponge.

[0014] Furthermore, the pipe withdrawal plug includes a conical plug head that cooperates with the inner wall of the barrel and can completely enter the barrel head. A plug column is arranged behind the conical plug head. A plurality of supporting ribs in contact with the conical plug head are arranged around the plug column. A push support is installed at the rear end of the plug column. The rear end of the plug column 201 and the rear end of the barrel 103 are both provided with knurling 6.

[0015] The beneficial effects of the utility model are as follows: (1) The device is small in size, exquisite in design, and has extremely low detection cost. (2) The detection process of the device is simple to operate, and no oil dripping will occur during the whole process, which is clean and hygienic. (3) Since the device adopts a hydrophobic sponge material soaked with a nano solution (also known as a nano coating) and a unique L-shaped shape, the concentration of the oil in contact with the detection card is pure and will not be affected by moisture, which greatly reduces the detection error. (4) The internal channel of the device is extremely convenient to clean, and it can be reused by simply replacing the hydrophobic sponge and the detection card. (5) When not in use, the device is sealed inside, and the hydrophobic sponge and the detection card can be stored for a long time without worrying about quality problems.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but only represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0030] Such as Figures 1 to 7As shown in the figure, the utility model includes a tube drawing cylinder 1 and a tube drawing plug 2. The tube drawing cylinder 1 includes a conical cylinder head 102 at the front end of the cylinder body 103. An oil suction port 101 capable of sucking oil is arranged in front of the cylinder head 102. The tube drawing plug 2 is installed in the cylinder body 103 of the tube drawing cylinder 1 to provide a suction force and a pushing force.

[0031] As Figures 1 to 5 shown in the figure, a set of symmetric detection mechanisms 3 are arranged on both sides of the cylinder body 103. The main body of the detection mechanism 3 is an "L"-shaped oil suction channel 301. The "L"-shaped design increases the oil transportation stroke, thereby improving the degree of oil suction and water drainage, and fully separating water. A hydrophobic sponge 4 in the shape of an "L" is installed in the oil suction channel 301. The hydrophobic sponge 4 is soaked in a nano-coating and can only absorb oil and is difficult to absorb water.

[0032] As Figure 3 and Figure 4 shown in the figure, the oil suction channel 301 is made of a transparent material for convenient observation. The side of the oil suction channel 301 is rotatably connected to a sealing cover 302 through a micro hinge 303. A button 305 capable of squeezing the hydrophobic sponge 4 is arranged on the sealing cover 302. The hydrophobic sponge 4 is located outside the inner wall of the cylinder body 103 to avoid interference with the tube drawing plug 2 and is in contact with the inner wall of the oil suction channel 301. A filter screen 307 and a detection card 5 are also installed in the oil suction channel 301. The filter screen 307 abuts against the rear end face of the hydrophobic sponge 4 to provide a channel for its extrusion deformation. The detection card 5 is clamped in the gap between the filter screen 307 and the rear end face of the oil suction channel 301.

[0033] As Figure 2 、 5 、6 shown in the figure, an annular sink is arranged at the part where the sealing cover 302 contacts the oil suction channel 301. A rubber ring 304 is installed in the sink to ensure sealing. The sealing cover 302 and the oil suction channel 301 are conveniently locked through a buckle 306. The button 305 is integrally in the shape of a "worker" character when viewed from the side, including an arc-shaped top cover 3051, a support column 3052 located outside the sealing cover 302, and an extrusion cover 3054 located inside. The support column 3052 is installed in the circular groove through hole of the sealing cover 302 and is respectively connected to the top cover 3051 and the extrusion cover 3054 at both ends. A spring 3053 is sleeved on the support column 3052 and the spring 3053 is located outside the sealing cover 302 to ensure complete reset. A leak-proof ring 3055 is arranged between the extrusion cover 3054 and the circular groove of the sealing cover 302. The inner side of the leak-proof ring 3055 abuts against the support column 3052 to prevent the internal oil from leaking from the gap when the spring 3053 resets and expands and contracts. The extrusion cover 3054 is directly opposite to the side of the "L"-shaped hydrophobic sponge 4 to prevent squeezing other components and ensure that only the hydrophobic sponge 4 is squeezed.

[0034] As Figure 7As shown in the figure, the tube extraction plug 2 includes a conical plug head 202 that fits with the inner wall of the cylinder body 103, and the conical plug head 202 can completely enter the cylinder head 102 so that the oil can be completely pushed out. A push-pull plug column 201 is arranged behind the conical plug head 202. A number of support ribs 203 that contact the conical plug head 202 are arranged around the plug column 201. A push support 204 that is easy to fix in the palm of the hand is installed at the tail end of the plug column 201. Knurling 6 for increasing friction is arranged at the tail end of the plug column 201 and the tail end of the cylinder body 103.

[0035] The working principle and operation process of the present utility model are as follows: (1) Place the index finger and middle finger on the front end of the detection mechanism 3 of the device, and fix the palm and thumb; draw the oil to be tested (i.e., the oil-water mixture) with one hand. (2) The oil is drawn into the cylinder body 103 and enters the oil absorption channels 301 on both sides along with the pressure. Since the L-shaped hydrophobic sponge 4 blocks the oil absorption channels 301, and the hydrophobic sponge 4 was soaked in a nano-solution before installation and belongs to a kind of nano material, a large number of water molecules cannot enter, and only grease is adsorbed. Finally, the hydrophobic sponge 4 is completely filled with grease. (3) The thumb and middle finger of one hand can be used to press the buttons 305 on both sides. The pressing cover 3054 on the button 305 will squeeze the internal hydrophobic sponge 4 to deform, and the grease in the hydrophobic sponge 4 is squeezed out and contacts the test card 5 through the filter screen 307. (4) The test card 5 will change color, and the tester observes and compares through the transparent oil absorption channel 301. (5) After the test is completed, the oil inside is squeezed out by pushing the tube extraction plug 2, then the sealing cover 302 is opened to take out the nano material hydrophobic sponge 4 and the test card 5, and the inside of the whole device is cleaned by drawing hot water, and then a new nano material hydrophobic sponge 4 and test card 5 are replaced for the next use. (6) When the device is not in use, the hydrophobic sponge 4 and the test card 5 can be placed in the oil absorption channel 301 for a long time. Since the internal environment is sealed, there is no need to worry about quality problems.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present utility model shall be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solutions of the present utility model.
