The number of the sealingmembers 2 is equal to that of the connectingopenings 12 formed in the upper end and the lower end of thecircumferential wall 11 of themain body 1. Each of the sealingmembers 2 is provided with acircumferential wall 21, said circumferential wall has a thickness between 10˜45 mm, and a connectingopening 22 formed in one end of thecircumferential wall 21 for matching with one of the connectingopenings 12 of themain body 1 by electric high frequency welding or heater welding. And, as shown inFIGS. 2 and 3 , the welding portions between themain body 1 and the sealingmembers 2 are all located around the circumferential wall of the storage tank, ensuring the whole storage tank to possess sufficient strength against pressure of a chemical stored in it, keeping the storage tank secure in use. - In addition, as shown in
FIGS. 1 and 2 again, each of the sealingmembers 2 is provided with a linkingportion 24 formed with an arc for jointing thecircumferential wall 21 and atop portion 23. In stead of a sharp corner designed in the conventional one, the linkingportion 24 is strong enough to withstand the pressure of a storing chemical. - Moreover, as shown in
FIGS. 2 and 3 , each of the sealingmembers 2 is also provided with a plurality of reinforcingribs 25 positioned among thetop portion 23 for strengthening the structure of the sealingmembers 2, so as to enable the storage tank to withstand more pressure, advancing security in service. - A second preferred embodiment of a chemical storage tank in the present invention, as shown in
FIGS. 4 and 5 , includes amain body 1 and sealingmembers 2, which are derived from those described in the first preferred embodiment. Thejointing portion 24 of thetop portion 23 and thecircumferential wall 21 of the sealingmember 2 is formed with an arc for preventing pressure in the chemical storage tank from directly attacking thejointing portion 24 to enhance safety of the chemical storage tank. Unlike the first preferred embodiment, thetop portion 23 of the sealingmember 2 of the second preferred embodiment is provided with no reinforcingribs 25. For facilitating combination with themain body 1, thetop portion 23 of the sealingmember 2 is formed with a downward-extendingcircumferential wall 26 that is covered around a partial circumferential wall of themain body 1, and then the main body and the sealingmembers 2 are combined together by high frequency welding or heat welding. - A third preferred embodiment of a chemical storage tank in the present invention, as shown in
FIG. 6 , includes amain body 1 and a sealingmember 2. Themain body 1 is the same as that described in the first preferred embodiment, but the sealingmember 2 is composed of a plurality ofunits 2A respectively shaped in advance and then welded together to form the sealingmember 2. As shown inFIG. 5 , thejointing portion 24 of both thetop portion 23 and thecircumferential wall 21 of the sealingmember 2 are arc-shaped for preventing thejointing portion 24 from being attacked directly by the pressure inside the chemical storage tank, thus able to elevate safety of the chemical storage tank. However, unlike the top portion in the first preferred embodiment, thetop portion 23 of the sealingmember 2 in the third preferred embodiment is provided with no reinforcingribs 25. Being closely combined with themain body 1, thetop portion 23 of the sealingmember 2 is formed with acircumferential wall 26 extending downward and covering a partial circumferential wall of themain body 1, and then themain body 1 and the sealingmember 2 are firmly combined together by high frequency welding or heat welding. - While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
