Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and more specifically, to a cement silo storage protection device. Background Technology

[0002] Cement storage management is crucial during tunnel construction. However, some tunnel projects are located deep in the mountains, in humid mountain environments. Existing cement silos generally employ simple sealed designs to keep the interior dry, but this structure is insufficient to completely isolate external moisture, especially in the high-humidity environment of tunnel construction sites. This causes the cement to gradually absorb moisture, leading to clumping, reduced strength, and ineffective moisture protection. This not only degrades cement quality and increases construction costs but also affects construction progress. Therefore, improving the moisture-proof performance of cement silos has become an urgent problem to be solved. Utility Model Content

[0024] Please see Figures 1-3 As shown, the main body of this embodiment is a cement silo storage protection device, including a silo body 1, which is located on top of a base 2. A monitoring module is also installed inside the silo body 1. A control unit 3 electrically connected to the monitoring module is installed outside the silo body 1. The silo body 1 includes an inner layer plate 4 and an outer layer plate 5, with an insulation layer 6 filling the space between the inner layer plate 4 and the outer layer plate 5. A feed inlet 7 is located at the top of the silo body 1, and a discharge outlet 8 is located at the bottom of the silo body 1, both of which are respectively provided with a first sealing mechanism and a second sealing mechanism. A dehumidification system electrically connected to the monitoring module is provided on the inner wall of the silo body 1.

[0025] Furthermore, the inner layer 4 is made of stainless steel, the outer layer 5 is made of galvanized steel, and the insulation layer 6 is tightly filled in the closed cavity between the two layers and adheres to the inner wall of the two layers.

[0026] Furthermore, the first sealing mechanism includes a sealing ring 9, which is embedded in an annular groove on the edge of the feed inlet 7. The feed inlet 7 is provided with a threaded locking cover 10, which presses the sealing ring 9 when it is closed on the feed inlet 7. The second sealing mechanism includes a manual butterfly valve 11 and a threaded gate valve 12 arranged from top to bottom on the discharge port 8. A water-swellable rubber strip 13 is provided between the manual butterfly valve 11 and the threaded gate valve 12.

[0027] Furthermore, the dehumidification system includes a circulating air duct 14 arranged along the outside of the chamber 1, and a rotary dehumidifier 15 fixed to the top of the chamber 1; the return air inlet of the circulating air duct 14 is opened on the side wall of the chamber 1, the air outlet of the circulating air duct 14 is connected to the rotary dehumidifier 15, and the air outlet of the rotary dehumidifier 15 faces the inside of the chamber 1; a backup power supply 16 electrically connected to the rotary dehumidifier 15 is installed on the outer side wall of the chamber 1.

[0028] Furthermore, the monitoring module includes a pressure sensor 17 installed at the sealing surface of the feed inlet 7, and a moisture meter 18 embedded in the inner wall of the silo body 1 at a corresponding position near the cement accumulation layer; a data transmission unit 19 is fixed on the top of the silo body 1, and the data transmission unit 19 is electrically connected to the pressure sensor 17 and the moisture meter 18 respectively; the data transmission unit 19 integrates a wireless communication module, and the wireless communication module communicates with a remote terminal through signals.

[0029] Furthermore, the sloping rainproof eaves 20 on the top of the silo body 1 are inclined outwards, and a water guide channel 21 arranged around the circumference of the silo body 1 is fixed below the edge of the eaves. The end of the water guide channel 21 is connected to the drainage ditch outside the silo body 1 through a pipe 22.

[0030] Furthermore, the monitoring module also includes a field audible and visual alarm 23 installed on the top of the chamber 1 and electrically connected to the data transmission unit 19.

[0031] This device employs a multi-layered chamber structure 1 to passively isolate external moisture. Chamber 1 is a composite structure consisting of an inner layer 4 (stainless steel plate), an insulation layer 6, and an outer layer 5 (galvanized steel plate). The two metal plates form a physical barrier, reducing the direct penetration of external humid air. The insulation layer 6 tightly fills the sealed cavity, not only reducing the temperature difference between the inside and outside of chamber 1 (preventing internal condensation), but also further preventing moisture from entering through the gaps in the plates. Structurally, this enhances the isolation capability against high-humidity external environments, surpassing the simple protection of a traditional single-layer chamber 1.

[0032] In addition, this device employs a multi-seal scheme for the two critical parts, the feed inlet 7 and the discharge outlet 8, which are prone to moisture leakage. The feed inlet 7 is tightly sealed by tightening the threaded locking cap 10 and pressing the sealing ring 9. The pressed sealing ring 9 can completely fill the gaps and prevent humid air from entering the feed inlet 7 in the reverse direction. The discharge outlet 8 adopts a dual valve design with a manual butterfly valve 11 and a threaded gate valve 12. A water-swellable rubber strip 13 is installed between the valves. Even if a small amount of moisture seeps in, the rubber strip expands after contact with water to further seal the gaps and prevent moisture from entering the silo 1 through the discharge outlet 8. This solves the problem of traditional cement silos having only a single valve seal and being prone to moisture leakage.

[0033] In addition, the chamber 1 is equipped with a rotary dehumidifier 15 and a circulating air duct 14 to form an active dehumidification cycle: the circulating air duct 14 draws out the air inside the chamber 1, and after being processed by the rotary dehumidifier 15, the dry air is sent back to the chamber 1, which can actively remove the small amount of moisture that may seep into the chamber and ensure that the interior maintains a low humidity environment.

[0034] It is worth mentioning that the backup power supply 16 ensures that the dehumidification system can continue to work when the power supply is unstable during tunnel construction, thus avoiding dehumidification interruption and moisture accumulation due to power outages.

[0035] In addition, the monitoring module achieves precise control of moisture-proof status through multi-dimensional perception and early warning: the pressure sensor 17 of the feed inlet 7 can monitor the pressure of the sealing surface and determine whether the seal of the feed inlet 7 has failed (such as the sealing ring 9 is loose); the moisture meter 18 on the inner wall of the silo 1 directly monitors the humidity near the cement accumulation layer and keeps track of the internal moisture level in real time; the data transmission unit 19 (including the wireless communication module) can remotely transmit data such as humidity and sealing status to the terminal, and the on-site audible and visual alarm 23 can immediately remind the staff when the humidity exceeds the standard or the seal fails, so as to achieve "early detection and early treatment" and avoid long-term accumulation of moisture that causes cement to become damp and clump.

[0036] It is worth mentioning that the sloping rainproof eaves 20 and water guide channels 21 on the top of the silo 1 can quickly drain rainwater, preventing rainwater from accumulating on the top of the silo 1 and seeping through the gaps in the silo top. At the same time, the water guide channels 21 lead rainwater to the external drainage ditch, reducing water accumulation and dampness on the ground around the silo 1, and indirectly reducing the risk of moisture intrusion at the bottom of the silo 1.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
