Description

Technical fields:

[0001] This utility model relates to the technical field of storage tanks, and more specifically to high-strength pressure-bearing vertical fixed storage tanks for chemical applications. Background technology:

[0002] Chemical storage tanks are key equipment in chemical industrial production, used to store various chemicals and raw materials. They can be classified by structure as follows: vertical tanks (larger capacity, suitable for large-scale storage); horizontal tanks (smaller capacity, suitable for small-scale storage or specific purposes); and spherical tanks (high strength and good pressure resistance, suitable for high-pressure storage). Currently, vertical tanks are the most common. These tanks consist of a cylindrical body with a base support at the bottom. An output pipe is installed in the middle of the base support, and vertical steel supports are installed on the tank body. These supports allow the tank to detach and facilitate the arrangement of the output pipeline. However, existing vertical tanks lack other supporting components besides the supports contacting the ground. When the tank is full of chemical raw materials, the weight of the materials mainly acts on the base support, which, apart from being supported by the supports on its outer ring, has no internal support. As the capacity of the vertical tank increases, a new support structure is needed to improve its pressure resistance. Utility model content:

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a high-strength, pressure-bearing, vertical, fixed storage tank for chemical applications. In addition to the load-bearing structure with added legs, the tank also has an internal support structure that works in conjunction with the legs. The overall support structure is easy to install and can effectively improve the pressure-bearing performance of the storage tank.

[0004] A high-strength, pressure-bearing, vertical, fixed storage tank for chemical applications includes a tank body. A conical base support is inserted and fixed to the bottom of the tank body. An interface is formed in the middle of the base support. The outer ring of the base support is bent into a cylindrical annular connecting edge, which is fixed to the inner wall of the tank body. The outer ring of the bottom of the tank body is provided with several channel steel-shaped support legs. The upper part of the support legs is formed with stepped grooves. The lower end face of the tank body and the connecting edge abut against the stepped surface of the grooves. The support legs are welded and fixed to the base support and the tank body respectively.

[0005] The middle of the support leg has a vertical slot that penetrates the upper surface of the support leg. An "I"-shaped connecting bracket is inserted into the slot. The connecting bracket has an upper and a lower inclined support rod that are staggered. The lower inclined support rod has a vertical positioning sleeve at its end, and the upper inclined support rod has a vertical internal threaded sleeve at its end. The internal threaded sleeve on the connecting bracket is located directly above the positioning sleeve of the adjacent connecting bracket and is screwed with a stud. The upper end of the stud abuts against the support ring, and the upper part of the support ring abuts against the support ring. The lower end of the stud passes through the positioning sleeve and is screwed with a pad. The lower end face of the pad is flush with the lower end face of the support leg.

[0006] Preferably, the upper surface of the support ring is conical and fits against the lower surface of the support ring;

[0007] The central axis of the tank body, the central axis of the base, and the central axis of the support ring are on the same straight line.

[0008] Preferably, the support legs are provided in at least four sets, the number of support legs is equal to the number of studs, and the support legs and studs are evenly distributed in a ring around the central axis of the tank.

[0009] Preferably, the diameter of the stud is equal to the inner diameter of the positioning sleeve;

[0010] The lower part of the positioning sleeve has cylindrical ring-shaped pads, and the lower end of the pads is formed with a disc-shaped base plate.

[0011] Preferably, the connecting bracket includes a middle plate inserted into the support leg, with an inner baffle and an outer baffle perpendicular to the middle plate formed at both ends, an upper inclined support rod and a lower inclined support rod formed on the outer baffle of the connecting bracket, and the outer baffle abutting against the side wall of the support leg; the inner baffle of the connecting bracket is located on the outside of the tank body and has several vertical rollers inserted therein, with the rollers abutting against the outer wall of the tank body.

[0012] Preferably, the legs of the connecting bracket are clamped between the legs and the tank body.

[0013] Preferably, the openings of the support legs at the bottom of the tank face outwards from the tank.

[0014] The beneficial effects of this utility model are as follows:

[0015] In addition to the load-bearing structure with added legs, this storage tank also has an internal support structure that works in conjunction with the legs. The overall support structure is easy to install and can effectively improve the pressure-bearing performance of the storage tank. Attached image description:

[0020] Example: See Figures 1 to 3 As shown, a high-strength pressure-bearing vertical fixed storage tank for chemical use includes a tank body 1. A conical base support 2 is inserted and fixed to the bottom of the tank body 1. An interface is formed in the middle of the base support 2. The outer ring of the base support 2 is bent into a cylindrical ring-shaped connecting edge 21, which is fixed to the inner wall of the tank body 1. The outer ring of the bottom of the tank body 1 is provided with several channel steel-shaped support legs 3. The upper part of the support legs 3 is formed with a stepped groove 31. The lower end face of the tank body 1 and the connecting edge 21 respectively abut against the stepped surface of the groove 31. The support legs 3 are welded and fixed together with the base support 2 and the tank body 1 respectively.

[0021] The middle of the support leg 3 has a slot 32 that runs vertically through the upper end face of the support leg 3. An "I"-shaped connecting bracket 4 is inserted into the slot 32. The connecting bracket 4 has an upper inclined support rod 43 and a lower inclined support rod 41 that are staggered upwards and downwards. The end of the lower inclined support rod 41 has a vertical positioning sleeve 42, and the end of the upper inclined support rod 43 has a vertical internal threaded sleeve 44. The internal threaded sleeve 44 on the connecting bracket 4 is located directly above the positioning sleeve 42 of the adjacent connecting bracket 4 and is screwed with a stud 5. The upper end of the stud 5 abuts against the support ring 6, and the upper part of the support ring 6 abuts against the support ring 6. The lower end of the stud 5 passes through the positioning sleeve 42 and is screwed with a pad 7. The lower end face of the pad 7 is flush with the lower end face of the support leg 3.

[0022] The upper surface of the support ring 6 is conical and fits into the lower surface of the support ring 6. The fit between the two can increase the support area and make the support more stable.

[0023] The central axis of the tank body 1, the central axis of the base 2, and the central axis of the support ring 6 are on the same straight line.

[0024] The support legs 3 are provided in at least four sets, and the number of support legs 3 is equal to the number of studs 5. The support legs 3 and studs 5 are evenly distributed in a ring around the central axis of the tank body 1.

[0025] The diameter of the stud 5 is equal to the inner diameter of the positioning sleeve 42; the stud 5 makes the positioning sleeve 42 and the internal threaded sleeve 44 concentric, and thus it can be known that the upper inclined support rod 43 and the lower inclined support rod 41 are symmetrical about the center line of the connecting bracket 4, and the connecting bracket 4 is also evenly distributed in a ring around the central axis of the tank body 1; in order to prevent the support ring 6 from moving, the lower part of the support ring 6 is formed with several positioning recesses 61, and the upper end of the stud 5 is inserted into the positioning recesses 61.

[0026] The lower part of the positioning sleeve 42 has a cylindrical ring-shaped pad 7, and the lower end of the pad has a disc-shaped base plate 71, so that the height of the pad 7 can be adjusted to make the base plate 71 and the support 3 flush.

[0027] The connecting bracket 4 includes a middle plate inserted into the support leg 3. The two ends of the middle plate are respectively formed with an inner baffle and an outer baffle perpendicular to the middle plate. The upper inclined support rod 43 and the lower inclined support rod 41 are formed on the outer baffle of the connecting bracket 4. The outer baffle abuts against the side wall of the support leg 3. The inner baffle of the connecting bracket 4 is located on the outside of the tank body 1 and has several vertical rollers 8 inserted therein. The rollers 8 abut against the outer wall of the tank body 1. When the support leg 3 is not welded to the tank body 1 and the base support 2, it can move on the tank body 1 based on the rollers 8. At the same time, the studs 5 are used to facilitate the uniform distribution of the support leg 3 in a ring on the tank body 1.

[0028] The support leg 3 of the connecting bracket 4 is clamped between the support leg 3 and the tank body 1, and the support leg 3 and the tank body 1 can limit the position of the connecting bracket 4.

[0029] The openings of the support legs 3 at the bottom of the tank 1 face outwards from the tank 1.

[0030] Working principle: This structure is a high-strength pressure-bearing vertical fixed storage tank for chemical use. The bottom of the tank is equipped with support legs 3 on the outer ring and studs 5 and support rings 6 on the inner side for support, so as to improve the support strength.

[0031] Meanwhile, the positioning of the support leg 3 and the stud 5 can be quickly positioned based on the connecting bracket 4, the internal threaded sleeve 44 and the positioning sleeve 42, and the installation and connection of its bottom support structure are convenient.

[0032] The embodiments described above are illustrative of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be as set forth in the claims.
