Description

Technical Field

[0001] The utility model relates to the technical field of cement storage, in particular to a cement silo which can prevent cement from getting damp. Background Art

[0002] Cement silos are facilities for storing cement, usually with reinforced concrete or metal structures. Cement is a water-hardening material, and its hardening process is achieved through chemical reactions between water and minerals in cement to form hydration products. If cement is damp, it may hydrate prematurely, thus losing its use value. Therefore, in order to ensure the quality and use of cement, cement silos need to prevent cement from getting damp, and take corresponding moisture-proof measures, such as ventilation, waterproof coatings, etc.

[0003] Traditional cement silos that prevent cement from getting damp usually have lids or covers to prevent rainwater from directly contacting the cement surface, reducing the possibility of cement getting damp. At the same time, ventilation holes or ventilation windows are opened in the cement silo to maintain air circulation in the silo and reduce moisture accumulation, thereby reducing the risk of cement getting damp.

[0004] The traditional cement silo that prevents cement from getting damp has the following problems: although the ventilation holes can help air circulation, the traditional ventilation hole design is usually kept in a normally open state, which may fail to prevent moisture from entering the cement silo under severe weather conditions. In addition, the ventilation windows need to be opened and closed manually on a regular basis, and cannot be adjusted in real time according to the humidity conditions inside the cement silo. Therefore, we propose a cement silo that prevents cement from getting damp. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a cement silo that prevents cement from getting damp. The ventilation can be adjusted according to the real-time humidity conditions, and protective measures can be automatically taken according to weather conditions to ensure that the internal environment of the cement silo is always in the best state, which can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cement silo for preventing cement from getting damp, comprising legs and a humidity sensor;

A single-chip microcomputer is arranged on the front side of the fixed block. The single-chip microcomputer is bidirectionally electrically connected with the humidity sensor. The ventilation can be adjusted according to the real-time humidity conditions, and protective measures can be automatically taken according to the weather conditions to ensure that the internal environment of the cement silo is always in the best condition.

[0010] Furthermore, it also includes four mounting columns, which are respectively fixedly connected to the top of the storage bin, and the tops of the four mounting columns are fixedly connected to the lower surface of a rainproof cover, which can effectively prevent rainwater from entering the interior of the storage bin.

[0012] Furthermore, it also includes fixing rods, which are fixedly connected to the top of the storage bin, and a fixed shell is fixedly connected to the middle part between the fixing rods to effectively protect the driving components of the ventilation mechanism.

[0013] Furthermore, the ventilation mechanism includes support rods and umbrella leaves. There are four support rods, which are rotatably connected to the upper end of the inner wall of the storage bin respectively. The inner ends of the four support rods extend to the interior of the fixed outer shell. The outer surfaces of the four support rods are fixedly connected with umbrella leaves. When in the vertical position, ventilation of the storage bin is achieved, and when in the horizontal position, rainwater can be prevented from entering.

[0014] Furthermore, the ventilation mechanism also includes an avoidance opening, a connecting plate, a turntable, a rotating shaft and a rotating shaft. The connecting plates are respectively fixedly connected to the inner ends of the four support rods, and the interior of the connecting plates is provided with avoidance openings. The rotating shaft is rotatably connected to the bottom wall of the fixed shell, and a turntable is fixedly provided on the upper end of the rotating shaft. The outer surface of the turntable is rotatably connected to four rotating shafts, and the outer ends of the four rotating shafts are all located inside the avoidance openings at adjacent ends. Multi-stage transmission realizes the coordinated rotation of the umbrella leaves.

[0015] Furthermore, the ventilation mechanism also includes gear 1, a motor and gear 2. The motor is installed on the lower surface of the fixed shell by bolts. The output shaft of the motor extends to the interior of the fixed shell. The top end of the output shaft of the motor is fixedly sleeved with gear 2.

When encountering bad weather, the rain cover 1 plays a good protective role, which can effectively prevent rainwater from entering the interior of the storage bin 3 and avoid the problem of cement getting damp and agglomerating. At the same time, the operator controls the motor 208 to reverse through the single-chip microcomputer 7, so that the four umbrella leaves 202 rotate to a horizontal state.
