Description

Technical Field

[0001] This utility model relates to the field of methylbenzoic acid production technology, specifically to a storage tank for the production of p-methylbenzoic acid with a protective structure. Background Technology

[0002] p-Toluenebenzoic acid is a white or light yellow crystalline powder with a melting point of 179-182℃ and a boiling point of 274-275℃. It is readily soluble in methanol and ether, sparingly soluble in hot water, and volatilizes with steam. Oxidation yields phthalic acid, which can be used as an intermediate in pharmaceuticals, photosensitive materials, pesticides, and organic pigments. It is mainly used in the manufacture of hemostatic aromatic acids, p-formonitrile, p-toluenechlorohydrin, and photosensitive materials. During production, raw materials need to be stored. Existing storage tanks typically have external protective structures to prevent collisions and impacts during transport. These structures are mostly designed with elastically retractable protective rods. However, exceeding these limits during actual protection can easily lead to deformation and further damage to the tank. Therefore, a p-toluenebenzoic acid production storage tank with a double protective layer and a protective structure is designed to further improve storage sealing safety. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figure 1-5 A storage tank for the production of p-methylbenzoic acid with a protective structure includes a storage tank 1 with arc-shaped openings 2 at both the top and bottom. A support frame 3 is fixedly installed at the bottom of the storage tank 1. The storage tank 1 is equipped with a storage sealing mechanism that can be raised and lowered. The storage tank 1 is equipped with a protective structure on the outside. The protective structure includes multiple protective rods 11 arranged circumferentially on the outside of the storage tank 1. Each protective rod 11 is connected to the storage tank 1 by an elastic mechanism.

[0023] Specifically, the elastic mechanism is set in two sets and is located at both ends of the protective rod 11. The elastic mechanism includes a U-shaped slide rod 12 fixedly installed at the end of the protective rod 11. A limit plate 14 and a fixing ring plate 13 are fixedly installed on the U-shaped slide rod 12. A positioning block 15 that slides horizontally with the U-shaped slide rod 12 is fixedly installed on the storage tank 1. A spring 16 is sleeved on the U-shaped slide rod 12. The two ends of the spring 16 are fixedly connected to the fixing ring plate 13 and the positioning block 15, respectively. When the protective rod 11 is pressed inward, the spring 16 is compressed, so that the U-shaped slide rod 12 moves horizontally to the side of the storage tank 1, which can buffer the impact on the protective rod 11. After the impact, under the action of the spring 16, the U-shaped slide rod 12 and the protective rod 11 slowly return to their original positions.

[0024] Specifically, the storage sealing mechanism includes two sealing blocks 4 fixedly connected by a fixed connecting rod 5. The two sealing blocks 4 can slide in the middle of the storage tank 1 through a seal to form a storage space with the storage tank 1. The fixed connecting rod 5 and the two sealing blocks 4 can be raised and lowered to form a gap between the upper sealing block 4 and the inner wall of the storage tank 1, so that materials can be put into the storage space through the gap. When the lower sealing block 4 is lowered to form a gap with the inner wall of the storage tank 1, materials can be discharged downward through the gap.

[0025] Specifically, it also includes a lifting adjustment mechanism for adjusting the lifting of the fixed connecting rod 5 and the sealing block 4. The lifting adjustment mechanism includes a fixed plate 7 fixedly installed on the top of the arc-shaped opening 2 located on the upper side. An adjusting screw 8 is rotatably connected to the fixed plate 7. The fixed connecting rod 5 and the sealing block 4 located on the upper side have an internal thread groove 9 that is threadedly connected to the adjusting screw 8. An adjusting knob 10 is fixedly installed on the top of the adjusting screw 8. By rotating the adjusting knob 10 and pressing the sealing block 4, the sealing block 4 can be raised or lowered through the threaded connection between the adjusting screw 8 and the internal thread groove 9.

[0026] Specifically, an arc-shaped cover 6 is fixedly installed on the top of each of the two sealing blocks 4, which facilitates the guidance of materials.
