DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] See also Figure 1-3 The utility model provides a concentrated sulfuric acid storage tank with high safety, including support legs 8 fixedly connected to both sides of the lower end of the concentrated sulfuric acid storage tank 1, an anti-dumping sleeve 2 is placed at the lower end of the support legs 8, the anti-dumping sleeve 2 is sleeved on the outer wall of the concentrated sulfuric acid storage tank 1, and a plurality of fixing structures 3 are symmetrically arranged on the inner wall of the anti-dumping sleeve 2. The fixing structure 3 is in contact with the side wall of the concentrated sulfuric acid storage tank 1, and the side wall of the concentrated sulfuric acid storage tank 1 is connected to the temporary storage tube 5 through the pressure relief structure 4. The lower end of the temporary storage tube 5 is fixedly connected with an air relief valve 6.

[0015] Concentrated sulfuric acid is stored in the concentrated sulfuric acid storage tank 1, and the support legs 8 protect the concentrated sulfuric acid storage tank 1. The anti-dumping sleeve 2 can ensure the stability of the concentrated sulfuric acid storage tank 1, and prevent the tank from tipping over and being damaged, thereby preventing sulfuric acid from leaking. The fixing structure 3 can better ensure the stability of the concentrated sulfuric acid storage tank 1. Through the cooperation of the pressure relief structure 4 and the temporary storage cylinder 5, when the pressure in the tank is large, the pressure relief will be automatically graded according to the pressure situation to ensure the use effect and the safety of the equipment. The material after pressure relief will remain in the temporary storage cylinder 5 and will be safely discharged through the air relief valve 6 to avoid direct discharge affecting the safety of the surrounding environment. The utility model has strong practicality.

[0016] The fixing structure 3 includes a screw 31 , which is screwed to the inner wall of the anti-dumping sleeve 3 . The inner end of the screw 31 is fixedly equipped with a top block 32 , which fits tightly against the side wall of the concentrated sulfuric acid storage tank 1 .

[0017] When it is necessary to adjust the fixed structure 3 to clamp the concentrated sulfuric acid storage tank 1, first rotate the screw 31 to adjust it to move in the fixed anti-dumping sleeve 2, drive the top block 32 to move, and clamp the concentrated sulfuric acid storage tank in the anti-dumping sleeve 2 to better ensure the stability of the placement of the concentrated sulfuric acid storage tank 1.

[0018] The pressure relief structure 4 includes a connecting pipe 48, which is connected to the side wall of the concentrated sulfuric acid storage tank 1, and the connecting pipe 48 is fixed to the inner wall of the temporary storage tube 5. The inner wall of the connecting pipe 48 is fixedly equipped with a sleeve 41, and one side of the inner wall of the connecting pipe 48 is fixedly equipped with a support plate 45. The inner wall of the support plate 45 is penetrated by a sliding rod 44, and the end of the sliding rod 44 is connected to a blocking block 43, which fits the inner wall of the sleeve 41. The inner wall of the sleeve 41 is embedded with multi-end through-tubes 42 at the upper and lower sides. The multi-end through-tube 42 at one end is connected to the inner wall of the sleeve 41, and the multi-end through-tube 42 at the other end extends to the outside of the sleeve 41. The outer wall of the sliding rod 44 is sleeved with a spring 46, one end of the spring 46 is connected to the blocking block 43, and the other end of the spring 46 is connected to the support plate 45. The upper and lower ends of the side wall of the blocking block 43 are fixedly equipped with limit rods 47, and the two limit rods 47 both penetrate the support plate 45.

[0019] When the pressure in the concentrated sulfuric acid storage tank 1 is too high, the pressure will enter the connecting pipe 48, and at the same time, it will push the block 43 to displace on the inner wall of the sleeve 41, and drive the slide bar 44 to displace against the inner wall of the support plate 45, while squeezing the spring 46 to deform it. When the block 43 gradually exposes the port of the multi-end through pipe 42, the pressure can be relieved through the multi-end through pipe 42. When the pressure is too high, the block 43 will be completely pushed out of the inner wall of the sleeve 41 for rapid pressure relief. The elastic force of the spring 46 needs to be less than the maximum pressure that the concentrated sulfuric acid storage tank 1 can withstand. The limit rod 47 can ensure the stability of the block 43 during displacement.

[0020] The inner wall of the anti-dumping sleeve 2 is fixedly equipped with a fixing seat 7 , and the fixing seat 7 is sleeved on the outer wall of the supporting leg 8 .

[0021] The fixing seat 7 can limit the supporting leg 8 so that it can be placed stably.

[0022] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
