Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, specifically a lime powder moisture-proof storage tank. Background Technology

[0002] Lime powder is a white powdery substance with calcium carbonate as its main component. It is most commonly used in the construction industry. Lime powder storage tanks are key equipment for storing, transporting and measuring lime powder. Their design must take into account requirements such as moisture prevention, anti-caking, dust prevention and efficient unloading.

[0003] Existing lime powder moisture-proof storage tanks typically rely solely on breather valves for moisture protection. Although these valves contain desiccants, their overall flow rate is low, resulting in inefficient dehumidification. Furthermore, the desiccant within the valve cannot be easily replaced. Therefore, a new type of lime powder moisture-proof storage tank needs to be designed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a lime powder moisture-proof storage tank to solve the problems mentioned in the background art, which are that existing lime powder moisture-proof storage tanks generally only use a breather valve for moisture protection. Although the breather valve is equipped with a desiccant, the overall flow rate of the breather valve is small, the dehumidification and moisture protection efficiency is low, and the desiccant inside the breather valve cannot be easily replaced.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a moisture-proof storage tank for lime powder, comprising a tank body, a motor fixed at the center of the top of the tank body, a stirring rod installed at the output end of the motor, an auger blade at the bottom end of the stirring rod, a pneumatic feed pipe and an inert gas inlet pipe installed on one side of the top of the tank body, a top mounting hole opened on the other side of the top of the tank body, the inner wall of the top mounting hole connected to the bottom end of a sealing seat, a sponge column fixedly installed on the bottom surface of the sealing seat, a positioning groove opened at the bottom of the sponge column, the inner wall of the positioning groove fitting against the top end of an extraction pipe, the extraction pipe penetrating and fixed to the top of one side of the tank body, the other end of the extraction pipe connected to one side of a top cover, an exhaust pipe fixedly installed on the other side of the top cover, an air pump installed on the exhaust pipe, a bottom shell installed at the bottom of the top cover, a middle partition plate fixedly installed on the bottom surface of the top cover, and a desiccant placed inside the bottom shell.

[0006] Preferably, the middle part of the stirring rod is rotatably connected to the inner wall of the tank body through a sealed bearing, and the auger blades at the bottom of the stirring rod are in contact with the inner wall of the bottom pipe of the tank body.

[0007] Preferably, the sealing seat and the top mounting hole are threaded together, and the front view cross-sectional shape of the sealing seat is "T" shaped.

[0008] Preferably, the length of the portion of the suction pipe that fits into the positioning groove is greater than 1 / 3 of the length of the sponge column, and the diameter of the sponge column is not less than 1.5 times the diameter of the suction pipe.

[0009] Preferably, the portions of the extraction pipe and the exhaust pipe located inside the top cover are both configured in an "L" shape, and the extraction pipe and the exhaust pipe are symmetrically distributed about the center of the top cover.

[0010] Preferably, the center of the partition plate and the center of the bottom shell are on the same vertical plane, the side of the partition plate is in close contact with the inner wall of the bottom shell, and the distance between the lower surface of the partition plate and the upper surface of the bottom of the bottom shell is less than 1 / 8 of the overall height of the bottom shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the lime powder moisture-proof storage tank adopts a new structural design, which can not only extract the inert gas in the tank body in a high-throughput manner and dehumidify it efficiently through the desiccant, but also connect the exhaust pipe with the inert gas inlet pipe to reuse the inert gas. At the same time, the bottom shell can be easily separated from the top cover, making it convenient to replace the desiccant.

[0012] 1. The end of the suction pipe is blocked by the sponge column and positioning groove to prevent excessive suction from carrying away lime powder. The sealing seat and sponge column can also be easily disassembled and cleaned from the top mounting hole to ensure that the suction pipe is smooth and not easily blocked.

[0013] 2. The gas inside the tank is extracted sequentially through the extraction pipe, the inside of the bottom shell, and the exhaust pipe by the air pump. The gas is efficiently dehumidified by the desiccant inside the bottom shell. The bottom shell can also be easily separated from the top cover for easy replacement of the desiccant. At the same time, the dried gas can be transported back to the tank body for recycling through the inert gas inlet pipe. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a moisture-proof storage tank for lime powder, comprising a tank body 1, a motor 2, a stirring rod 3, an auger blade 4, a pneumatic feed pipe 5, an inert gas inlet pipe 6, a top mounting hole 7, a sealing seat 8, a sponge column 9, a positioning groove 10, an extraction pipe 11, a top cover 12, an exhaust pipe 13, an extraction pump 14, a bottom shell 15, a middle partition 16, a desiccant 17, and a sealed bearing 18. The motor 2 is fixed at the center of the top of the tank body 1, and the stirring rod 3 is installed at the output end of the motor 2. An auger blade 4 is provided at the bottom end of the stirring rod 3. A pneumatic feed pipe 5 and an inert gas inlet pipe are installed on one side of the top of the tank body 1. The inlet pipe 6 and the top mounting hole 7 are provided on the other side of the top of the tank body 1. The inner wall of the top mounting hole 7 is connected to the bottom of the sealing seat 8. A sponge column 9 is fixedly installed on the bottom surface of the sealing seat 8. A positioning groove 10 is provided at the bottom of the sponge column 9. The inner wall of the positioning groove 10 is attached to the top of the suction pipe 11. The suction pipe 11 is fixedly installed on the top of one side of the tank body 1. The other end of the suction pipe 11 is connected to one side of the top cover 12. An exhaust pipe 13 is fixed on the other side of the top cover 12. An air pump 14 is installed on the exhaust pipe 13. A bottom shell 15 is installed at the bottom of the top cover 12. A middle partition 16 is fixedly installed on the bottom surface of the top cover 12. A desiccant 17 is placed inside the bottom shell 15.

[0023] In this example, the middle part of the stirring rod 3 is rotatably connected to the inner wall of the tank body 1 through the sealed bearing 18, and the auger blade 4 at the bottom of the stirring rod 3 is in contact with the inner wall of the bottom pipe of the tank body 1. The above structural design ensures that the stirring rod 3 can rotate stably and the lime powder can be stably conveyed through the auger blade 4.

[0024] The sealing seat 8 and the top mounting hole 7 are connected by threads. The front view cross section of the sealing seat 8 is "T" shaped. The above structural design allows the sealing seat 8 and the top mounting hole 7 to be easily disassembled and stably installed, which facilitates the cleaning of the sponge column 9.

[0025] Specifically, the length of the part of the suction pipe 11 that fits into the positioning groove 10 is greater than 1 / 3 of the length of the sponge column 9, and the diameter of the sponge column 9 is not less than 1.5 times the diameter of the suction pipe 11. The above structural design ensures the isolation effect of the sponge column 9 and prevents lime powder from entering the suction pipe 11.

[0026] Furthermore, the portions of the extraction pipe 11 and the exhaust pipe 13 located inside the top cover 12 are both set in an "L" shape. The extraction pipe 11 and the exhaust pipe 13 are symmetrically distributed about the center of the top cover 12. The above structural design allows the gas to smoothly exit from the exhaust pipe 13 after entering the inner space of the bottom shell 15 through the extraction pipe 11.

[0027] In this embodiment, the center of the partition plate 16 and the center of the bottom shell 15 are on the same vertical plane. The side of the partition plate 16 is in close contact with the inner wall of the bottom shell 15. The distance between the lower surface of the partition plate 16 and the upper bottom surface of the bottom shell 15 is less than 1 / 8 of the overall height of the bottom shell 15. The above structural design extends the path of gas flow in the bottom shell 15, ensuring that the gas can fully contact the desiccant 17.

[0028] Working principle: During operation, inert gas enters the tank body 1 through the inert gas inlet pipe 6 to protect the lime powder. The vacuum pump 14 is periodically activated, allowing gas inside the tank body 1 to pass through the sponge column 9 and enter through the vacuum pipe 11. Figure 5 The space on the left side of the partition 16 inside the bottom shell 15 comes into contact with the desiccant 17 and flows through the space between the bottom end of the partition 16 and the bottom of the inner wall of the bottom shell 15 to the space on the right side of the partition 16, and is finally discharged through the exhaust pipe 13. The exhaust pipe 13 can be connected to the inert gas inlet pipe 6 to allow the dried inert gas to be reintroduced into the tank body 1.

[0029] The sealing seat 8 can be rotated periodically to separate from the top mounting hole 7, and the lime powder adsorbed on the sponge column 9 can be cleaned. The bolts connecting the top of the bottom shell 15 and the top cover 12 can also be removed periodically to separate the bottom shell 15 from the top cover 12, and the desiccant 17 inside the bottom shell 15 can be cleaned and replaced. This is the working principle of the lime powder moisture-proof storage tank.

[0030] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
