[0002] N,N-Diethylaniline is a colorless to yellow oily liquid, mainly used as a curing and accelerator for unsaturated polyester adhesives. It can also be used as an accelerator for ethylene-based polymerized rubber and anaerobic adhesives, as well as a plastic curing agent, chemical reaction deacidifying agent, metal corrosion inhibitor, etc. It is also used as a raw material for manufacturing triphenylmethane dyes, azo dyes, basic dyes, tetraethyl ketone, pharmaceuticals, and color developers.
[0003] N,N-Diethylaniline is mostly in liquid form, so it needs to be stored in tanks. When the tank contains the raw material, pressure will be exerted from the inside of the tank to the outside. Excessive pressure can easily cause the tank to rupture. Since N,N-Diethylaniline is water-soluble and has a certain degree of toxicity, damage to the tank can cause significant harm.
[0004] Therefore, this application proposes an N,N-diethylaniline storage tank that reduces the pressure on the tank and extends its service life. Utility Model Content
[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an N,N-diethylaniline storage tank to solve the problem that the storage tank is easily damaged in the prior art.
[0006] To achieve the above and other related objectives, this utility model provides an N,N-diethylaniline storage tank, comprising: a storage section and an isolation section, wherein the isolation section is disposed inside the storage section and divides the interior of the storage section into two spaces, and a sealing section is provided on the top of the isolation section to seal the isolation section;
[0007] The storage unit includes a storage tank body, with a feed pipe arranged at the bottom axis of the storage tank body and a discharge pipe arranged at the bottom edge of the storage tank body;
[0008] The isolation section includes an isolation tube, the bottom of which extends to the bottom of the storage tank body to divide the internal space of the storage tank body. The inlet of the feed pipe is located at the center of the isolation tube. A connecting flange is provided on the outer surface of the isolation tube. The bottom of the connecting flange overlaps with the top of the storage tank body and is fixed by a connector.
[0009] The sealing part covers the upper end of the isolation tube to seal the interior of the storage tank and the isolation tube.
[0010] Preferably, a backflow preventer is provided at the connection between the feed pipe and the storage tank body, and the backflow preventer is higher than the inner bottom of the storage tank body.
[0011] Preferably, the outer surface of the isolation tube is provided with side filter holes, and the bottom of the isolation tube is provided with bottom filter holes.
[0012] Preferably, a connecting sealing tube is provided at the axial center of the inner bottom of the isolation tube, and the inner wall of the connecting sealing tube is in contact with the outer surface of the check device.
[0013] Preferably, the bottom filter hole is located between the inner wall of the isolation tube and the connecting sealing tube.
[0014] Preferably, the side filter holes and the bottom filter holes are divided into multiple filter areas at equal intervals, with gaps between each filter area, and the positions of the side filter holes and the bottom filter holes are matched.
[0015] The width of each filter zone is equal to the width of the gap between adjacent filter zones.
[0016] Preferably, the sealing part includes a sealing cap, and the outer surface of the upper end of the isolation tube is provided with a threaded head, and the sealing cap is threadedly connected to the threaded head.

[0020] As described above, the N,N-diethylaniline storage tank of this utility model has the following beneficial effects:
[0021] 1. This utility model divides the internal space of the storage tank into two independent spaces by setting an isolation tube inside the storage tank body. When storing N,N-diethylaniline, the pressure is shared by the storage tank body and the isolation tube respectively. With a slight reduction in volume, the pressure on the storage tank body is greatly reduced, thereby improving the service life and safety of the storage tank body.
[0022] 2. This utility model provides side filter holes on the outer surface and bottom of the isolation tube. When N,N-diethylaniline is injected, the side filter holes filter the N,N-diethylaniline, improving the purity of the N,N-diethylaniline discharged from the outlet pipe. During storage, the side filter holes are sealed with filter hole sealing plates, which isolates the internal space of the storage tank and distributes the pressure, thus achieving the effect of filtering N,N-diethylaniline.
[0023] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0037] like Figures 1-3 As shown, this utility model provides an N,N-diethylaniline storage tank, including a storage section 1 and an isolation section 2. The isolation section 2 is disposed inside the storage section 1, dividing the interior of the storage section 1 into two spaces, allowing N,N-diethylaniline to be stored separately in the storage section 1 and the isolation section 2, thereby reducing the pressure of N,N-diethylaniline on the storage section 1. This improves the safety and service life of the storage section 1. A sealing section 3 is provided at the top of the isolation section 2 to seal the isolation section 2, further enhancing the safety of storing N,N-diethylaniline.
[0038] Specifically, the storage unit 1 includes a storage tank body 101, which is an open-top tank. A feed pipe 102 is axially located at the bottom of the storage tank body 101 for injecting N,N-diethylaniline into the tank body 101. A discharge pipe 103 is located at the bottom edge of the storage tank body 101 for discharging the N,N-diethylaniline stored inside the tank body 101.
[0039] The isolation section 2 includes an isolation tube 201, which is inserted into the interior of the storage tank 101 from its upper opening. The bottom of the isolation tube 201 extends to the bottom of the storage tank 101, dividing the internal space of the storage tank 101 and thus forming two independent storage spaces within the tank, reducing the pressure of N,N-diethylaniline on the inner wall of the storage tank 101. The opening of the feed pipe 102 is located at the center of the isolation tube 201. When N,N-diethylaniline is injected through the feed pipe 102, it enters the space inside the isolation tube 201. Alternatively, the storage tank 101 can be filled with N,N-diethylaniline first, and then the isolation tube 201 can be installed to separate the N,N-diethylaniline within the storage tank 101. A connecting flange 202 is provided on the outer surface of the isolation tube 201. The bottom of the connecting flange 202 overlaps with the top of the storage tank body 101, thereby limiting the depth to which the isolation tube 201 can be inserted into the storage tank body 101. It is then secured with connectors to ensure stability after installation. A sealing part 3 covers the upper end of the isolation tube 201 to seal the interior of both the storage tank body 101 and the isolation tube 201, preventing the risk of N,N-diethylaniline volatilization and leakage.
[0040] like Figure 3 As shown, in some embodiments, a check valve 1021 is provided at the connection between the feed pipe 102 and the storage tank body 101. After the injection of N,N-diethylaniline into the storage tank body 101 stops, the pressure of the N,N-diethylaniline will cause the check valve 1021 to close, preventing backflow of N,N-diethylaniline. The check valve 1021 is higher than the inner bottom of the storage tank body 101.
[0041] like Figures 2-3 and Figures 5-6 As shown, in some embodiments, the outer surface of the isolation tube 201 of this invention is provided with a side filter hole 203. When N,N-diethylaniline is injected into the storage tank body 101 through the feed pipe 102, the N,N-diethylaniline will enter the interior of the storage tank body 101 through the side filter hole 203, and the N,N-diethylaniline can be filtered through the side filter hole 203. When the N,N-diethylaniline is discharged through the discharge pipe 103, impurities in the N,N-diethylaniline can be reduced. During the storage process, the side filter hole 203 can be sealed to form two storage spaces inside the storage tank body 101. The bottom of the isolation tube 201 is provided with a bottom filter hole 205. After long-term use, a large amount of impurities will accumulate inside the isolation tube 201. During the removal of the isolation tube 201, the residual N,N-diethylaniline will enter the interior of the storage tank body 101 through the bottom filter hole 205.
[0042] like Figure 3 As shown, in some embodiments, a connecting sealing tube 204 is provided at the axial center of the inner bottom of the isolation tube 201 of this utility model, and the inner wall of the connecting sealing tube 204 is in contact with the outer surface of the check valve 1021. During normal storage, the side filter hole 203 and the bottom filter hole 205 are sealed. The connecting sealing tube 204 and the check valve 1021 cooperate to seal the connecting sealing tube 204, preventing N,N-diethylaniline from leaking into the interior of the storage tank 101. Sediment will fall into the gap between the outer surface of the connecting sealing tube 204 and the inner wall of the isolation tube 201. When the isolation tube 201 is removed for cleaning, this reduces the amount of impurities entering the storage tank 101 through the connecting sealing tube 204.
[0043] like Figure 3 and Figure 4 As shown, in some embodiments, the bottom filter hole 205 of this invention is located between the inner wall of the isolation tube 201 and the connecting sealing tube 204. When the isolation tube 201 is lifted, the residual N,N-diethylaniline will be discharged into the interior of the storage tank 101 through the bottom filter hole 205 located between the inner wall of the isolation tube 201 and the outer surface of the connecting sealing tube 204. The precipitate will remain between the inner wall of the isolation tube 201 and the outer surface of the connecting sealing tube 204.
[0044] like Figure 2 and Figure 3 As shown, in some embodiments, the side filter holes 203 and bottom filter holes 205 of this invention are equally spaced into multiple filter areas, with gaps between each filter area, and the positions of the side filter holes 203 and bottom filter holes 205 are matched. The width of each filter area is equal to the width of the gap between adjacent filter areas. Therefore, during use, the side filter holes 203 and bottom filter holes 205 can be easily covered or uncovered.
[0045] like Figures 1-4 As shown, in some embodiments, the sealing part 3 of this utility model includes a sealing cap 301, and a threaded head 206 is provided on the outer surface of the upper end of the isolation tube 201. The sealing cap 301 is threadedly connected to the threaded head 206. This facilitates sealing the opening of the isolation tube 201 through the sealing cap 301. Furthermore, after the sealing cap 301 seals the opening of the isolation tube 201, the sealing cap 301 is not prone to falling off or rotating.
[0046] like Figure 4In some embodiments, a filter hole sealing plate 302 is provided at the bottom of the sealing cap 301 of this invention, and the outer surface of the filter hole sealing plate 302 is in contact with the inner wall of the isolation tube 201. When N,N-diethylaniline is injected into the storage tank 101 through the feed pipe 102, the filter hole sealing plate 302 is misaligned with the side filter hole 203 by rotating the sealing cap 301. After the N,N-diethylaniline injection is completed, the filter hole sealing plate 302 is aligned with the side filter hole 203 by rotating the sealing cap 301 to seal the side filter hole 203. At this time, two independent storage spaces are formed inside and outside the isolation tube 201 to share the pressure of N,N-diethylaniline and improve the service life of the tank.
[0047] like Figure 4 As shown, in some embodiments, the number of filter hole sealing pieces 302 is the same as the number of filter areas, and the gap between each filter hole sealing piece 302 is the same as the distance between two adjacent filter areas. When the sealing cover 301 is rotated, all filter hole sealing pieces 302 are displaced, thereby achieving the effect of sealing and connecting all filter areas.
[0048] like Figure 7 As shown, in some embodiments, the cross-section of the filter hole sealing sheet 302 of this invention is L-shaped to cover the side filter hole 203 and the bottom filter hole 205, and the width of the filter hole sealing sheet 302 is the same as the width of a single filter area. To prevent leakage at the bottom filter hole 205, the filter hole sealing sheet 302 simultaneously seals both the side filter hole 203 and the bottom filter hole 205.
[0049] The specific usage process of this utility model is as follows:
[0050] Rotate the sealing cap 301 to misalign the filter hole sealing plate 302 with the side filter hole 203. Then, N,N-diethylaniline is injected into the isolation tube 201 through the feed pipe 102. As the N,N-diethylaniline enters the storage tank 101 through the side filter hole 203, impurities are blocked and filtered by the side filter hole 203. After the N,N-diethylaniline injection is completed, rotate the sealing cap 301 again to seal the filter hole sealing plate 302 against the side filter hole 203 and the bottom filter hole 205, creating two independent spaces inside and outside the isolation tube 201 to reduce the pressure of N,N-diethylaniline on the inner wall of the storage tank 101. When discharging N,N-diethylaniline, the N,N-diethylaniline stored inside the storage tank 101 is discharged first, and then the N,N-diethylaniline stored in the isolation tube 201 is discharged after misaligning the side filter hole 203 and the filter hole sealing plate 302. After prolonged use, the storage tank 101 and the isolation tube 201 can be separated by unscrewing the bolts, and then the isolation tube 201 can be cleaned. During the cleaning of the isolation tube 201, it is not necessary to drain the N,N-diethylaniline from the storage tank 101, thus improving convenience.
[0051] In summary, the N,N-diethylaniline storage tank of this invention divides the internal space of the storage tank 101 into two independent spaces by setting an isolation tube 201 inside the storage tank body 101. When storing N,N-diethylaniline, the pressure is shared by the storage tank body 101 and the isolation tube 201 respectively. With a slight reduction in volume, the pressure on the storage tank body 101 is significantly reduced, thereby improving the service life and safety of the storage tank body 101.
[0052] This invention provides side filter holes 203 on the outer surface and bottom of the isolation tube 201. When N,N-diethylaniline is injected, the side filter holes 203 filter the N,N-diethylaniline, improving the purity of the N,N-diethylaniline discharged from the discharge pipe 103. During storage, the filter hole sealing plate 302 is used to seal the side filter holes 203, isolating and sharing the pressure inside the storage tank 101, thus achieving the effect of filtering N,N-diethylaniline.
[0053] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.
[0054] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
