Technical Field

[0001] The utility model relates to the technical field of silos, in particular to a powder silo used for calcium powder. Background Art

[0002] Calcium powder is an important inorganic chemical raw material, widely used in construction, chemical industry, metallurgy and environmental protection. Calcium powder is a weakly alkaline powder, which is difficult to dissolve in water but soluble in acid. On Earth, calcium powder is a very common substance, mainly found in minerals such as aragonite, calcite, chalk, and limestone.

[0003] The storage device for calcium powder is a powder silo, which is common in factories. Powder silos have important applications in industry, especially in factories for powder processing and handling. The powder silos used for calcium powder storage in the prior art have good waterproof performance, but they do not have the corresponding dehumidification function. When the front end of the calcium powder is not completely dried and placed in the powder silo for storage, it is easy to cause the calcium powder to agglomerate, which seriously affects the subsequent use of the calcium powder. Therefore, it is necessary to propose a powder silo for calcium powder with a dehumidification function. Utility Model Content

In addition, the design of the exhaust component allows the powder bin to be vented to the outside Exhaust is carried out. When there is a lot of moisture stored in the moisture-absorbing cotton, in order to avoid re-moisture, the calcium powder in the powder bin can be emptied regularly, and the heating resistor wire is started to heat, so that the moisture in the moisture-absorbing cotton is transformed into water vapor and then discharged to the outside through the exhaust pipe on the top, so that the moisture-absorbing cotton is restored to a dry state, thereby making the moisture-absorbing cotton have good moisture absorption performance, thereby providing a guarantee for the dehumidification function of the powder bin when storing calcium powder later. Through the coordinated action of the above-mentioned moisture-absorbing cotton, heating resistor wire and exhaust assembly, the dehumidification effect of the powder bin is guaranteed, the storage quality of the powder is guaranteed, and the practicality of the utility model is improved.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] Through the above structure, the first control valve 4 is arranged on the discharge pipe 3, and the second control valve 6 is arranged on the delivery pipe 5. When the calcium powder is stored, by closing the first control valve 4 and the second control valve 6, a relatively stable storage environment is maintained inside the powder silo 1 to prevent the calcium powder stored inside the powder silo 1 from getting damp.

[0032] In this embodiment, the foot pad assembly 12 includes a column leg 121, a mounting hole 122 is opened at the top of the column leg 121, the internal size of the mounting hole 122 is adapted to the size of the plug-in column seat 10, a stabilizing disc seat 124 is fixedly installed at the bottom of the column leg 121, a reinforcing arc rod 125 is fixedly connected between the column legs 121, and a mounting screw rod 123 is screwed on the side wall of the column leg 121, and the inner end of the mounting screw rod 123 coincides with the position of the limiting hole 11.

[0033] Through the above structure, by rotating the installation screw rod 123 to make the inner end of the installation screw rod 123 move inwardly of the installation hole 122, the inner end of the installation screw rod 123 can be inserted into the limiting hole 11 opened on the side of the plug-in column seat 10, so that the plug-in column seat 10 can complete the plug-in and fixing function in the installation hole 122.

[0034] In this embodiment, an inner lining plate 13 is installed inside the powder silo 1, and the inner side of the inner lining plate 13 is filled with moisture-absorbing cotton 15. Through holes 14 are evenly distributed on the inner lining plate 13, and heating resistor wires 16 are evenly distributed inside the moisture-absorbing cotton 15. An exhaust component 7 is evenly installed on the top of the powder silo 1. The exhaust component 7 includes an exhaust pipe 71. An inclined rod 72 is fixedly installed on the outer side of the exhaust pipe 71, and a cone cap 73 is fixedly installed on the upper end of the inclined rod 72.

[0035] Through the above structure, when calcium powder is stored in the powder bin 1, under the action of the moisture-absorbing cotton 15, the moisture in the calcium powder enters the moisture-absorbing cotton 15 through the through hole 14 and is stored in the moisture-absorbing cotton 15, so that the calcium powder remains dry and prevents the calcium powder from being affected by moisture and causing agglomeration.

[0036] In this embodiment, the powder bin 1 is made of low-carbon stainless steel, and the plug-in column seat 10 is a hexagonal support column.

[0037] Through the above structure, the powder silo 1 is made of low-carbon stainless steel, so that the powder silo 1 has sufficient strength and durability, and the service life of the powder silo 1 can be increased.

[0038] In this embodiment, a reinforcing rod 9 is fixedly welded between the legs 8, and the reinforcing rod 9 is a circular steel pipe.

[0039] Through the above structure, the provision of the reinforcing rod 9 increases the overall bearing strength of the supporting leg 8 .

[0040] In this embodiment, the exhaust pipe 71 is connected to the inside of the powder silo 1 and a one-way air valve is installed inside the exhaust pipe 71 .

[0041] Through the above structure, the exhaust direction of the one-way air valve is from inside to outside, so the powder silo 1 can exhaust to the outside through the exhaust pipe 71, while the outside air cannot flow into the inside of the powder silo 1 through the exhaust pipe 71, thereby preventing the outside humid air from entering the powder silo 1, thereby causing the calcium powder in the powder silo 1 to agglomerate.

[0042] In this embodiment, the inner lining plate 13 is arranged along the inner side wall of the powder silo 1, the through hole 14 is arranged obliquely downward and is a gradually decreasing diameter hole, and the outer side of the heating resistance wire 16 is wrapped with high-strength polyester enameled nickel-chromium wire.

At the same time, the temperature transmitted by the heating resistance wire 16 to the moisture-absorbing cotton 15 is mild and stable, which will not cause spontaneous combustion of the moisture-absorbing cotton 15, thereby fully improving the safety of use.

[0044] In the utility model, when in use, calcium powder is added to the powder bin 1 through the feeding pipe 5. When the calcium powder is added, the second control valve 6 on the feeding pipe 5 is closed. When it is necessary to discharge the material, the first control valve 4 on the discharge pipe 3 is opened to start discharging the material. When the calcium powder is stored in the powder bin 1, under the action of the moisture-absorbing cotton 15, the moisture in the calcium powder enters the moisture-absorbing cotton 15 through the through hole 14 and is stored in the moisture-absorbing cotton 15. The through hole 14 in the lining plate 13 is arranged obliquely downward and the through hole 14 is a diameter shrinkage hole, so the moisture stored in the moisture-absorbing cotton 15 is difficult to be discharged through the through hole 14. Flow to the outside of the inner lining plate 13 to avoid the re-moisture phenomenon of the calcium powder. When there is a lot of water vapor stored in the moisture-absorbing cotton 15, in order to avoid the re-moisture phenomenon, the calcium powder in the powder silo 1 can be regularly emptied, and the heating resistor 16 is started to heat, so that the water vapor in the moisture-absorbing cotton 15 is transformed into water vapor and then discharged to the outside through the exhaust pipe 71 on the top, so that the moisture-absorbing cotton 15 is restored to a dry state, thereby making the moisture-absorbing cotton 15 have good moisture absorption performance, providing a guarantee for the dehumidification function of the powder silo 1 when storing calcium powder later, so that the calcium powder can be kept in a dry state during storage, and the calcium powder is prevented from agglomerating.
