Description

Technical Field

[0001] The utility model relates to the technical field of chemical raw materials, in particular to a storage tank for chemical raw materials. Background Art

[0002] When carrying out sewage treatment work, raw materials such as sulfuric acid, hydrochloric acid, nitric acid, sodium hydroxide, and bleaching water, hydrogen peroxide, ammonia water, PAC, and PMC are required. Some of the above raw materials need to be stored using a storage device before use.

[0003] For example, a storage device for chemical raw material reagents with the publication number CN219791149U drives the air flow inside and outside the storage box through a structure such as a suction fan and a suction duct, avoiding the occurrence of moisture in the storage tank. Through the cooperation of the filter cloth on the suction duct, the loss of raw materials during the dehumidification of powdered chemical raw materials is avoided. However, a large amount of raw materials are directly stacked in the storage tank. Even if the air flow in the storage tank is smooth, the air flow passes through the inside of the stacked raw materials, resulting in limited dehumidification effect. Therefore, a storage tank for chemical raw materials is proposed for improvement. Summary of the Utility Model

[0004] The purpose of the present utility model aims to solve at least one of the technical defects.

[0028] Air inlet holes 8 are provided on both the side and the bottom of the tank body 1. An exhaust fan 9 is arranged at the top of the tank body 1. A feed pipe 10 is fixedly connected to the bottom of the feed hopper 3. A distributing pipe 11 is fixedly connected to the side of the feed pipe 10. A storage pipe 12 is fixedly connected to the bottom end of the distributing pipe 11. Vent holes 13 are provided on the side of the storage pipe 12. A breathable cloth 14 is arranged inside the storage pipe 12. A material collecting pipe 15 is fixedly connected to the bottom end of the storage pipe 12.

[0029] Embodiment 1: A support plate is arranged on one side of the feed hopper 3. The sealing plate 4 is rotatably connected to the support plate through a rotating shaft. A dial block is arranged at one end of the sealing plate 4 away from its rotating shaft. Both the feed hopper 3 and the discharge pipe 5 are arranged in the middle of the tank body 1. The tank body 1 provides an installation space for the storage structure and separates the storage structure from the outside world, avoiding damage to the storage structure caused by accidental contact with external structures. The legs 2 support the tank body 1, ensuring the stability of the tank body 1 and providing a certain height for the tank body 1 to provide an installation space for structures such as the discharge pipe 5. The feed hopper 3 is used to add raw materials to be stored to the storage structure. By arranging a support plate on its side and a sealing plate 4, the top surface of the feed hopper 3 can be blocked by the sealing plate 4 when not in use, preventing external objects from falling into the feed hopper 3.

[0030] Embodiment 2: A baffle is provided at the rear end of the slot 6, and a dial block is fixedly connected to the bottom surface of the opening and closing plate 7. The air inlet hole 8 on the side surface of the tank body 1 is arranged below the tank body 1, and a filter screen is arranged in the air inlet hole 8. The discharge pipe 5 is used to discharge the raw materials in the storage structure for use when needed. The opening and closing plate 7 controls the opening and closing of the discharge pipe 5, and the slot 6 provides restraint for the opening and closing plate 7 to prevent the opening and closing plate 7 from displacing in other directions. The dial block provided on the bottom surface of the opening and closing plate 7 facilitates the staff to dial the opening and closing plate 7. The air inlet hole 8 allows external gas to enter the tank body 1, providing conditions for the air flow inside and outside the tank body 1. The exhaust fan 9 can drive the gas flow to form a circulating air flow inside and outside the tank body 1.

[0031] Embodiment 3: There are several distribution pipes 11 which are evenly arranged around the feeding pipe 10. Both the distribution pipes 11 and the aggregating pipe 15 are obliquely arranged, and air permeable holes 13 are also provided on the aggregating pipe 15. A corrosion-resistant layer is coated on the air permeable cloth 14, and the air permeable cloth 14 is also arranged inside the aggregating pipe 15. The bottom end of the aggregating pipe 15 is fixedly connected to the discharge pipe 5 from the side. The raw materials in the feeding hopper 3 will enter the feeding pipe 10 under the action of gravity, and enter each distribution pipe 11 from the feeding pipe 10, and then fall into each storage pipe 12. By providing air permeable holes 13 on each storage pipe 12, distribution pipe 11 and aggregating pipe 15, when gas flow occurs inside the tank body 1, it will affect the raw materials in the storage pipe 12, distribution pipe 11 and aggregating pipe 15 through the air permeable holes 13, preventing the raw materials from getting damp.

[0032] The working principle of the present utility model is as follows:

[0033] S1. Import the raw materials into the feeding hopper 3. The raw materials in the feeding hopper 3 will enter the feeding pipe 10 under the action of gravity, and enter each distribution pipe 11 from the feeding pipe 10, and then fall into each storage pipe 12.

[0034] S2. Start the exhaust fan 9. The exhaust fan 9 drives the gas flow, allowing external gas to enter the tank body from the air inlet hole 8 and discharging the gas inside the tank body 1 from the exhaust fan 9. The air flow acts on the raw materials through the air permeable holes 13 to dehumidify the raw materials.

[0035] S3. When the raw materials are needed, dial the opening and closing plate 7 to open the discharge pipe 5, and the raw materials are discharged from the discharge pipe 5.

[0036] Compared with the prior art, the present utility model has the following beneficial effects over the prior art:

[0037] 1. For this chemical raw material storage tank, by setting up structures such as the feed hopper 3, air inlet hole 8, exhaust fan 9, blanking pipe 10, distribution pipe 11, storage pipe 12, ventilation hole 13, ventilation cloth 14, and material collecting pipe 15, when storing chemical raw materials, the raw materials are introduced into the feed hopper 3. The raw materials in the feed hopper 3 will enter the blanking pipe 10 under the action of gravity and then enter each distribution pipe 11 from the blanking pipe 10, and then fall into each storage pipe 12. The raw materials stored in the storage pipe 12 have sufficient contact surface with the external space through the ventilation holes 13. When gas flow is generated in the tank body 1, it will affect the raw materials in the storage pipe 12, distribution pipe 11, and material collecting pipe 15 through the ventilation holes 13, avoiding the raw materials from getting damp. It effectively avoids the problem that the raw materials are piled up in the storage tank, resulting in the inability of the air flow to dehumidify the raw materials, and the storage effect is better.

[0038] 2. For this chemical raw material storage tank, by setting up structures such as the blanking pipe 10, distribution pipe 11, and material collecting pipe 15, it enables the staff to add raw materials into the storage tank without individually pouring the raw materials into each storage pipe 12 one by one. At the same time, when using the raw materials, there is no need to take materials from each storage pipe 12, making it more convenient to use.
