Technical Field
[0001] This utility model relates to the field of chemical raw material storage technology, specifically a ventilated and moisture-proof container for storing chemical raw materials. Background Technology
[0002] A chemical storage tank is a container used to store various liquid or gaseous chemicals. It is typically made of corrosion-resistant materials to ensure the safety and stability of the chemicals during storage.
[0003] To achieve the above functions, a prior art Chinese patent (publication number: CN219173248U) discloses a chemical storage tank, relating to the field of chemical production equipment technology. Its key technical features are: a storage tank body with an opening at the top and a sealing cap on the opening; an outer protective shell fitted over the outer side of the storage tank body; and the lower end of the storage tank body fixedly mounted on the base plate of the outer protective shell via support columns. One side of the upper port of the outer protective shell is hinged to one side of a movable cover, and the movable cover is connected to the upper port of the outer protective shell via multiple connecting units. The top of the movable cover has a gas filling port, and the bottom of the outer protective shell has a leak detection assembly. The outer protective shell and the movable cover form a sealed space outside the storage tank body, isolating the storage tank body from the external environment. When chemicals leak from the storage tank body, it effectively prevents direct exposure of chemicals to the external environment, thus avoiding harm to the environment and human health.
[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation: chemical raw materials are usually stored in sealed containers, and existing chemical raw material storage tanks are generally integrated sealed structures, which makes it difficult to drain the moisture inside the tank. Furthermore, solid raw materials are prone to accumulate during storage, generating heat that can cause the chemical raw materials to denature. Utility Model Content
[0005] The purpose of this utility model is to provide a ventilated and moisture-proof tank for storing chemical raw materials, so as to solve the problems in the above-mentioned background technology that the existing chemical raw material storage layer is generally an integrated sealed structure, which is not convenient for draining the moisture inside the tank, and the solid raw materials are prone to accumulate during storage, generating heat and causing the chemical raw materials to denature.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a ventilated and moisture-proof tank for storing chemical raw materials, including an outer tank, a storage tank fixedly connected inside the outer tank, and connecting rings fixedly connected to the top and bottom outer sides of the storage tank, and the storage tank and the outer tank are connected to each other through the connecting rings;
[0007] A circulation chamber is formed between the inner side of the outer tank and the outer side of the storage tank. The top of the storage tank is provided with a feed inlet. An installation chamber is fixedly connected to the outer side of the feed inlet. The inner side of the installation chamber is provided with an opening that communicates with the inside of the feed inlet. A first interface is provided on one side of the installation chamber.

[0008] Preferably, the storage tank is fixedly connected with vertically distributed circulation pipes, which are distributed in a ring at equal intervals inside the storage tank, and the upper and lower ends of the circulation pipes are respectively connected to the top and bottom of the circulation cavity.
[0009] Preferably, the upper end of the circulation pipe is provided with a ventilation hole, a one-way valve is fixedly connected inside the circulation pipe, and the one-way valve is located above the ventilation hole. The one-way valve is also located at the connection between the upper end of the circulation pipe and the storage tank.
[0010] Preferably, a reversing valve is installed between the first interface and the second interface. The reversing valve has two output ends, wherein the first output end is fixedly connected to a first input pipe, the second output end is fixedly connected to a second input pipe, and the input end of the reversing valve is fixedly connected to an output pipe. The first input pipe and the first interface are interconnected, and the second input pipe and the second interface are interconnected.
[0011] Preferably, a third interface is fixedly connected to one side of the bottom of the outer tank, and the third interface is connected to the inside of the circulation chamber.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This type of ventilated and moisture-proof tank for storing chemical raw materials features a circular and equidistantly distributed circulation pipe, allowing gas to penetrate the raw material layer evenly. In this mode, the one-way valve remains open, allowing airflow to pass directly through the connection between the upper end of the circulation pipe and the storage tank, forming a through-flow airflow channel. This design effectively promotes temperature uniformity inside the tank and prevents localized heat accumulation in the raw materials.
[0016] The airflow creates a positive pressure environment inside the storage tank, forcing the gas to enter the pipe body through the ventilation hole at the top of the circulation pipe. During this process, the one-way valve automatically closes due to the air pressure, ensuring that all airflow must pass through the small-diameter ventilation hole, forming a low-speed and uniform airflow distribution. After the gas completes the moisture adsorption in the installation chamber, it finally flows back to the bottom of the circulation chamber to complete the circulation. Attached Figure Description

[0024] 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.
[0025] Example 1: Please refer to Figures 1-3 and Figure 5This utility model provides the following technical solution: a ventilated and moisture-proof tank for storing chemical raw materials, including an outer tank 1, a storage tank 2 fixedly connected inside the outer tank 1, and connecting rings 3 fixedly connected to the top and bottom outer sides of the storage tank 2, and the storage tank 2 and the outer tank 1 are connected to each other through the connecting rings 3; a circulation chamber 4 is formed between the inner side of the outer tank 1 and the outer side of the storage tank 2, a feed inlet 5 is provided at the top of the storage tank 2, an installation chamber 6 is fixedly connected to the outer side of the feed inlet 5, and an opening communicating with the inside of the installation chamber 6 is provided on the inner side of the installation chamber 6, a first interface 7 is provided on one side of the installation chamber 6, and a second interface 8 communicating with the inside of the circulation chamber 4 is provided at the top of the outer tank 1; vertically distributed circulation pipes 9 are fixedly connected inside the storage tank 2, and the circulation pipes 9 are distributed in a ring at equal intervals inside the storage tank 2, and the upper and lower ends of the circulation pipes 9 communicate with the top and bottom of the circulation chamber 4, respectively; circulation... A ventilation hole 10 is provided at the upper end of the pipe 9. A one-way valve 11 is fixedly connected inside the circulation pipe 9 and is located above the ventilation hole 10. The one-way valve 11 is located at the connection between the upper end of the circulation pipe 9 and the storage tank 2. A reversing valve 12 is installed between the first interface 7 and the second interface 8. The reversing valve 12 has two output ends. The first output end is fixedly connected to the first input pipe 13, and the second output end is fixedly connected to the second input pipe 14. The input end of the reversing valve 12 is fixedly connected to the output pipe 15. The first input pipe 13 and the first interface 7 are connected to each other, and the second input pipe 14 and the second interface 8 are connected to each other. A third interface 16 is fixedly connected to one side of the bottom of the outer tank 1. The third interface 16 is connected to the inside of the circulation chamber 4. The third interface 16 and the output pipe 15 are connected by a pipe, and an air pump 17 is installed in the middle of the pipe.
[0026] A three-dimensional airflow channel is formed through the circulation chamber 4 between the outer tank 1 and the storage tank 2. When the system is started, the air pump 17 delivers the gas at the bottom of the circulation chamber 4 to the reversing valve 12 through the output pipe 15 via the third interface 16. The reversing valve 12 has two working modes: circulation mode and dehumidification mode. When the material is stored inside the storage tank 2, its height does not exceed the ventilation hole 10.
[0027] In circulation mode, the reversing valve 12 switches to the second input pipe 14 passage. At this time, the air pump 17 re-injects the gas at the bottom of the circulation chamber 4 into the top of the circulation chamber 4 through the output pipe 15 and the second interface 8. The airflow forms a vertical flow from top to bottom in the circulation chamber 4, and at the same time enters the storage tank 2 through the openings at the upper end of each circulation pipe 9. Since the circulation pipes 9 are distributed in a ring at equal intervals, the gas can penetrate the raw material layer evenly. The one-way valve 11 remains open in this mode, allowing the airflow to pass directly through the connection between the upper end of the circulation pipe 9 and the storage tank 2 to form a through airflow channel. This design effectively promotes the temperature balance inside the tank and prevents local heat accumulation in the raw material.
[0028] When switching to dehumidification mode, the reversing valve 12 switches the output pipe 15 to the first input pipe 13 passage. At this time, the gas output by the air pump 17 enters the installation chamber 6 through the first interface 7 and diffuses to the feed inlet 5 area through its internal opening. The airflow forms a positive pressure environment inside the storage tank 2, forcing the gas to enter the pipe body through the ventilation hole 10 at the upper end of the circulation pipe 9. During this process, the one-way valve 11 automatically closes due to the air pressure, ensuring that all airflow must pass through the smaller diameter ventilation hole 10 to form a low-speed and uniform airflow distribution. After the gas completes the moisture adsorption in the installation chamber 6, it finally flows back to the bottom of the circulation chamber 4 to complete the circulation.
[0029] Example 2: Based on Example 1, please refer to... Figures 4-6 The following structure is also disclosed: the storage tank 2 has a discharge port 18 at the bottom, a control valve 19 is installed inside the discharge port 18, a water-absorbing block 20 is installed inside the installation chamber 6, and a sealing cover 21 is sleeved on the outside of the inlet 5; the sealing cover 21 and the top of the installation chamber 6 are connected to each other by a hand-tightening screw, and the water-absorbing block 20 is installed inside the sealed space formed by the installation chamber 6 and the sealing cover 21, and a removable sealing plug 22 is installed on the inner side of the top of the inlet 5.
[0030] The device adds a discharge port 18 and a control valve 19 to the bottom of the storage tank 2. When unloading is required, the opening can be precisely controlled by the handle transmission mechanism to achieve controllable discharge of raw materials. The water-absorbing block 20 set in the installation chamber 6 is composed of silica gel and activated carbon composite. It is installed in the sealed space formed by the sealing cover 21 and can absorb moisture in the gas and filter dust impurities.
