[0029] It should be noted that this daily chemical preparation storage tank is preferably applicable to storing detergents whose main components include one or more of surfactants, alkaline auxiliaries, sodium carbonate, sodium sulfate, or fatty acid alkanolamide.

[0030] As Figure 1 , Figure 2 and Figure 3 shown, a daily chemical preparation storage tank includes: a tank body 1, a fixed cylinder 2 arranged inside the tank body 1, and a sampling assembly arranged inside the fixed cylinder 2; the fixed cylinder 2 is a hollow structure, with the top penetrating to the top of the tank body 1, and several sampling holes 21 are opened on the side of the fixed cylinder 2; the sampling assembly includes: a sampling cylinder 3 arranged inside the fixed cylinder 2, several storage cavities 31 opened inside the sampling cylinder 3, and several sampling holes 32 opened on the side of the sampling cylinder 3; several sampling heads 33 are fixed on the side of the sampling cylinder 3, the sampling holes 32 penetrate to the inside of the storage cavity 31 near the top, and the sampling heads 33 penetrate to the inside of the storage cavity 31 near the bottom; several connecting columns 4 are arranged between several sampling holes 21 and several sampling holes 32, one end of the connecting column 4 is fixed to the inside of the fixed cylinder 2, and an opening and closing assembly for connecting or closing the sampling holes 21 and the sampling holes 32 is arranged inside the connecting column 4.

[0031] It should be noted that the numbers of the sampling holes 21, the storage cavities 31, the sample injection holes 32, the sample outlet heads 33 and the connecting columns 4 are the same; the inner diameters of the sampling holes 21, the sample injection holes 32 and the connecting columns 4 are the same and they are coaxially arranged; when sampling the daily chemical preparation stored inside the tank body 1, since the fixed cylinder 2 is a hollow structure and its top end penetrates through to the top of the tank body 1, after placing the sampling cylinder 3 inside the fixed cylinder 2, a plurality of sample injection holes 32 on the side of the sampling cylinder 3 are butted with one end of a plurality of connecting columns 4, so that the sample injection holes 32 are communicated with the inside of the tank body 1 through the connecting columns 4 and the sampling holes 21. With the cooperation of the opening and closing assembly, the sampling holes 21 and the sample injection holes 32 can be communicated, and the daily chemical preparations at different depths outside the fixed cylinder 2 can be correspondingly sampled through a plurality of sampling holes 21 into a plurality of storage cavities 31 at different positions inside the sampling cylinder 3. After taking out the sampling cylinder 3 from the inside of the fixed cylinder 2, the daily chemical preparations in a plurality of storage cavities 31 can be taken out through a plurality of sample outlet heads 33 on the side of the sampling cylinder 3, and the daily chemical preparations in a plurality of storage cavities 31 can be subjected to quality inspection, so that the daily chemical preparations at different depths can be obtained, ensuring the accuracy during sampling inspection.

[0032] In some embodiments, a feed pipe 9 is fixed to the top of the tank body 1, and a discharge pipe 91 is fixed to the bottom; electromagnetic valves are arranged on the sides of both the feed pipe 9 and the discharge pipe 91; by opening the electromagnetic valve on the side of the feed pipe 9, the daily chemical preparation can be conveyed into the tank body 1 through the feed pipe 9 for storage, and by opening the electromagnetic valve on the side of the discharge pipe 91, the daily chemical preparation can be discharged from the inside of the tank body 1 through the discharge pipe 91.

[0033] In some embodiments, a support base 10 is fixed to the bottom of the tank body 1, and the support base 10 can support the tank body 1; the tank body 1 is threadedly connected with a top cover 11 at the top of the fixed cylinder 2, and a sealing ring is arranged at the connection between the top cover 11 and the top of the tank body 1. With the arrangement of the top cover 11, after unscrewing the top cover 11 from the top of the tank body 1, the sampling cylinder 3 can be placed inside the fixed cylinder 2. After taking out the sampling cylinder 3 from the inside of the fixed cylinder 2, the top cover 11 can be threadedly connected to the top of the tank body 1, and the sealing ring ensures the sealing performance of the connection; an observation window 12 is arranged on the side of the tank body 1, and with the arrangement of the observation window 12, it is convenient for the staff to observe the condition inside the tank body 1 from the outside through the observation window 12.

[0034] As Figure 4As shown, in some embodiments, the opening and closing assembly includes: a connection groove 41 formed inside the connection column 4, a circular ring 42 disposed inside the connection groove 41, and a plurality of hinges 43 surrounding the middle of the circular ring 42; a plurality of fixing blocks 44 are fixed inside the circular ring 42, one side of the plurality of fixing blocks 44 is hinged with a plurality of connecting rods 45, one side of the plurality of hinges 43 is hinged with the inner side of the connection groove 41, and the other side is hinged with one end of the connecting rod 45; a limiting member for limiting the rotation of the circular ring 42 when the circular ring 42 rotates and a power source for providing a rotational force for the circular ring 42 are provided on the side surface of the circular ring 42.

[0035] It should be noted that when the sampling hole 32 on the side surface of the sampling cylinder 3 is docked with one end of the connection column 4 for sampling, a rotational force is provided for the circular ring 42 by the power source. When the circular ring 42 rotates, the limiting member can limit the rotation of the circular ring 42 during rotation. When the circular ring 42 rotates, a plurality of fixing blocks 44 inside it will rotate synchronously. Since one end of the connecting rod 45 is hinged with one side of the fixing block 44 and the other end is hinged with one side of the hinge 43, a plurality of hinges 43 can be driven by the plurality of connecting rods 45. With the hinge point on the inner side of the connection groove 41 as the center, the plurality of hinges 43 are synchronously flipped and unfolded in the middle of the circular ring 42, so that the sampling hole 21 and the sampling hole 32 can be communicated. The daily chemical preparation stored inside the tank body 1 can enter the storage cavity 31 through the sampling hole 21, the connection column 4 and the sampling hole 21. After sampling, the plurality of hinges 43 are closed, and then the sampling is completed. The sampling process is sealed, thus avoiding impurities or pollutants from entering the inside of the tank body 1 due to sampling inspection.

[0036] In some embodiments, the limiting member includes: a plurality of arc-shaped grooves 5 formed on the surface of the circular ring 42, and a plurality of convex blocks 51 clamped inside the plurality of arc-shaped grooves 5; the smaller-diameter end of the convex block 51 is fixed to the inner side of the connection groove 41.

[0037] It should be noted that the circular ring 42 and the arc-shaped grooves 5 are both coaxially arranged with the connection column 4, and the number of the hinges 43, the fixing blocks 44, the connecting rods 45, the arc-shaped grooves 5 and the convex blocks 51 are the same; when the circular ring 42 rotates, the plurality of arc-shaped grooves 5 on the surface of the circular ring 42 will slide along the side surfaces of the plurality of convex blocks 51 for limiting, so as to play a role in limiting the rotation of the circular ring 42 during the rotation process.

[0038] In some embodiments, the power source includes: a plurality of hinge blocks 6 fixed on one side of the circular ring 42 and the inner side of the connection groove 41, and an electric telescopic rod 61 disposed between the plurality of hinge blocks 6; one end of the electric telescopic rod 61 is internally hinged with the hinge block 6 on one side of the circular ring 42, and the other end is internally hinged with the hinge block 6 on the inner side of the connection groove 41.

[0039] It should be noted that starting the extension or contraction of the electric telescopic rod 61 can drive the ring 42 to rotate through the hinge block 6, thereby providing a rotational force for the ring 42.

[0040] As Figure 3 shown, in some embodiments, tapered tubes 7 are provided on both sides of the hinge 43. The larger-diameter end of the tapered tube 7 is fixed to the inner side of the connection groove 41, and the smaller-diameter end is lapped with one side of the hinge 43.

[0041] It should be noted that through the setting of the tapered tube 7, since the larger-diameter end of the tapered tube 7 is fixed to the inner side of the connection groove 41 and the smaller-diameter end is lapped with one side of the hinge 43, it can provide a path guidance for the daily chemical preparation entering the connection column 4, ensuring that the daily chemical preparation smoothly enters the sampling cylinder 3 during sampling.

[0042] As Figure 5 shown, in some embodiments, a handle 8 is fixed to the top of the sampling cylinder 3, and a plurality of sliders 81 are fixed to the side of the sampling cylinder 3. A plurality of concave slide rails 82 are fixed to the inner side of the fixed cylinder 2. One side of the plurality of sliders 81 is slidably connected to the inner side of the plurality of concave slide rails 82.

[0043] It should be noted that through the setting of the handle 8, the user holds the handle 8, which is convenient for driving the sampling cylinder 3 to be taken out of or put into the fixed cylinder 2. When the sampling cylinder 3 is put into the fixed cylinder 2, by aligning the sampling hole 32 on the side of the sampling cylinder 3 with the sampling hole 21 and sliding one side of the plurality of sliders 81 on the side of the sampling cylinder 3 into the inner side of the plurality of concave slide rails 82, it can play a limiting role when the sampling cylinder 3 is put into the fixed cylinder 2, ensuring the accuracy of the alignment position of the sampling hole 32.

[0044] When the utility model is in use, the top cover 11 is unscrewed from the top of the tank body 1. The sampling hole 32 on the side of the sampling cylinder 3 is aligned with the sampling hole 21, and one side of several sliding blocks 81 on the side of the sampling cylinder 3 is slid into the inner side of several concave slide rails 82, which can play a role in limiting the position when the sampling cylinder 3 is placed in the fixed cylinder 2, ensuring the accuracy of the alignment position of the sampling hole 32, so that several sampling holes 32 on the side of the sampling cylinder 3 are butted against one end of several connecting columns 4. When sampling, the electric telescopic rod 61 is started to contract, and the hinge block 6 can drive the ring 42 to rotate. Several arc-shaped grooves 5 on the surface of the ring 42 will slide along the side surfaces of several convex blocks 51, so as to play a role in limiting the rotation during the rotation of the ring 42. At the same time, several fixing blocks 44 inside will be driven to rotate synchronously. Since one end of the connecting rod 45 is hinged to one side of the fixing block 44 and the other end is hinged to one side of the hinge 43, several connecting rods 45 can drive several hinges 43. Taking the hinge point inside the connecting groove 41 as the center of the circle, several hinges 43 are synchronously flipped and unfolded in the middle of the ring 42, so as to connect the sampling hole 21 and the sampling hole 32. The daily chemical preparations at different depths outside the fixed cylinder 2 can correspondingly enter the connecting column 4 through several sampling holes 21. The conical tube 7 can provide a path guide for the daily chemical preparations entering the connecting column 4, ensuring that the daily chemical preparations pass through the sampling hole 32 smoothly during sampling and are sampled into several storage cavities 31 at different positions inside the sampling cylinder 3. After sampling, several hinges 43 are closed, and the sampling cylinder 3 is taken out of the fixed cylinder 2 by holding the handle 8. The daily chemical preparations in several storage cavities 31 can be taken out through several sampling heads 33 on the side of the sampling cylinder 3, and the daily chemical preparations in several storage cavities 31 can be subjected to quality inspection, so as to obtain the daily chemical preparations at different depths, ensuring the accuracy of sampling and detection.
