Description

Technical Field

[0001] This utility model relates to the field of building material storage equipment technology, and in particular to a cement silo. Background Technology

[0002] Cement silos, as key facilities for cement storage, play a vital role in many industries, including construction. They can store large quantities of cement, providing a stable and continuous supply to construction sites and other locations, ensuring the smooth progress of projects, preventing construction interruptions or delays due to cement shortages, greatly improving construction efficiency, and reducing transportation costs.

[0003] Currently, during the use of cement silos, the temperature of cement tends to rise during storage due to its own heat of hydration and the influence of external environmental factors. High temperatures accelerate the hydration reaction process of cement, causing it to set and harden prematurely, resulting in clumping. This not only seriously affects the fluidity and uniformity of cement, making unloading difficult, but also reduces the activity and strength of cement, affecting its quality. Therefore, we have proposed a cement silo to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology and to propose a cement silo.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cement silo includes a cement silo body and a fixed opening on the cement silo body. A ventilation pipe is fixedly installed on the inner wall of the fixed opening, and a cooling mechanism is provided on the ventilation pipe.

[0007] The cooling mechanism includes multiple air outlet pipes fixedly installed on the inner side wall of the cement silo. The ventilation pipes and the air outlet pipes are connected. A motor is fixedly installed on the inner side wall of the ventilation pipe. A rotating shaft is fixedly installed on the output shaft of the motor. Multiple spiral fan blades are fixedly sleeved on the rotating shaft.

[0008] Preferably, a perforated support ring is fixedly sleeved on the inner wall of the ventilation duct, and the outer wall of the motor and the inner wall of the perforated support ring are fixedly connected.

[0009] Preferably, multiple air outlet ducts on the same floor are arranged in a ring array on the outer wall of the ventilation duct.

[0010] Preferably, dehumidifying and drying mesh plates are fixedly installed on the inner walls of both the ventilation duct and the air outlet duct.

[0011] Preferably, the top and bottom of the cement silo are respectively fixedly installed with multiple feed pipes and one discharge pipe.

[0012] Preferably, the ventilation duct is provided with a vibrating material mechanism, which includes multiple mounting holes on the outer wall of the ventilation duct, multiple vibrating metal rods fixedly mounted on the inner wall of the mounting holes, multiple extension rods fixedly mounted on the vibrating metal rods located outside the ventilation duct, multiple fixing collars fixedly mounted on the rotating shaft, and flexible rubber striking plates that can contact the vibrating metal rods fixedly mounted on the fixing collars.

[0013] Preferably, the multiple mounting holes on the same layer are arranged in a ring array on the outer wall of the ventilation duct.

[0014] Preferably, the vertical distance between the end of the vibrating metal rod located inside the ventilation duct and the rotating shaft is less than the vertical distance between the outer side of the flexible rubber impact plate and the rotating shaft.

[0015] The beneficial effects of this utility model are as follows:

[0016] Through the interaction of the cement silo body, ventilation ducts, cooling mechanism, and vibrating material mechanism, the ventilation ducts and cooling mechanism, with the help of a motor and spiral fan blades, achieve air circulation within the silo, effectively reducing cement temperature, delaying cement setting and hardening, preventing caking, and maintaining good fluidity and activity. A dehumidifying and drying mesh plate keeps the ventilation ducts dry, preventing the cement from becoming damp and deteriorating. The vibrating material mechanism uses a rotating shaft and flexible rubber impact plates to vibrate the vibrating metal rods, preventing cement compaction and caking, ensuring smooth unloading, improving the overall storage and use performance of the cement silo, and ensuring stable and reliable cement quality.

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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-3 A cement silo includes a cement silo body 1 and a fixed opening 2 on the cement silo body 1. A ventilation pipe 3 is fixedly installed on the inner wall of the fixed opening 2. Multiple feed pipes 10 and a discharge pipe 11 are fixedly installed on the top and bottom of the cement silo body 1, respectively.

[0023] To further explain, the feed pipe 10 and the discharge pipe 11 facilitate the entry and exit of cement into and out of the cement silo 1.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a cooling mechanism is provided on the ventilation pipe 3; the cooling mechanism includes multiple air outlet pipes 4 fixedly installed on the inner wall of the cement silo 1, the ventilation pipe 3 and the air outlet pipes 4 are connected, a motor 5 is fixedly installed on the inner wall of the ventilation pipe 3, a multi-hole support ring 8 is fixedly sleeved on the inner wall of the ventilation pipe 3, the outer wall of the motor 5 and the inner wall of the multi-hole support ring 8 are fixedly connected, a rotating shaft 6 is fixedly installed on the output shaft of the motor 5, and multiple spiral fan blades 7 are fixedly sleeved on the rotating shaft 6.

[0025] To further explain, the cooling mechanism uses a motor 5 to drive a rotating shaft 6 and a spiral fan blade 7 to rotate, causing air to circulate within the ventilation duct 3 and the exhaust duct 4. This accelerates air circulation within the silo, effectively removing the heat generated by the cement during storage, preventing the cement from deteriorating or clumping due to excessive temperature, and extending the cement's shelf life. On the other hand, the connection between the ventilation duct 3 and the exhaust duct 4 ensures that the cooling airflow can be evenly distributed to all areas within the silo, improving the uniformity and comprehensiveness of the cooling effect.

[0026] like Figure 2 As shown, multiple air outlet ducts 4 on the same floor are arranged in a ring array on the outer wall of the ventilation duct 3.

[0027] To further explain, this layout allows the cooling air blown out from the air outlet duct 4 to cover the interior space of the cement silo 1 at a relatively uniform angle and distance, avoiding excessive cooling in some areas while insufficient cooling in others, making the temperature field distribution inside the silo more uniform, further improving the overall cooling effect on the cement, and ensuring the consistency of cement quality throughout the silo.

[0028] like Figure 1 As shown, dehumidifying and drying mesh plates 9 are fixedly installed on the inner walls of both the ventilation duct 3 and the air outlet duct 4.

[0029] To further explain, the dehumidifying drying mesh plate 9 can absorb moisture from the air, reduce humidity inside the warehouse, maintain the dryness of the cement, and maintain the cement in a good storage condition.

[0030] like Figure 1 and Figure 2As shown, a vibrating material mechanism is provided on the ventilation pipe 3. The vibrating material mechanism includes multiple mounting holes 16 opened on the outer wall of the ventilation pipe 3. The multiple mounting holes 16 in the same layer are arranged in a ring array on the outer wall of the ventilation pipe 3. Multiple vibrating metal rods 12 are fixedly installed on the inner wall of the mounting holes 16. Multiple extension rods 13 are fixedly installed on the vibrating metal rods 12 located outside the ventilation pipe 3. Multiple fixing collars 14 are fixedly installed on the rotating shaft 6. A flexible rubber striking plate 15 that can contact the vibrating metal rods 12 is fixedly installed on the fixing collars 14.

[0031] To further explain, when the rotating shaft 6 rotates, the flexible rubber striking plate 15 on the fixed collar 14 in the vibrating material mechanism moves with the rotating shaft 6 and periodically strikes the vibrating metal rod 12, causing the vibrating metal rod 12 to vibrate and transmit the vibration to the inside of the cement silo 1. This vibration can prevent cement from accumulating and compacting in the silo for a long time, keeping the cement in a loose state, which facilitates subsequent unloading and conveying operations, improves the smoothness and efficiency of unloading from the cement silo, and reduces problems such as unloading blockage caused by caking.

[0032] like Figure 1 and Figure 2 As shown, the vertical distance between the end of the vibrating metal rod 12 located inside the ventilation duct 3 and the rotating shaft 6 is less than the vertical distance between the outer side of the flexible rubber impact plate 15 and the rotating shaft 6.

[0033] To further explain, this design ensures that the flexible rubber striking plate 15 can effectively strike the vibrating metal rod 12, so that the vibrating metal rod 12 generates sufficient vibration amplitude and energy.

[0034] The functional principle of this utility model can be explained through the following operation methods:

[0035] Cement storage: Cement is transported into cement silo 1 through the inlet on cement silo 1 for storage.

[0036] Cooling start: Start the motor 5 inside the ventilation pipe 3. The motor 5 drives the rotating shaft 6 to rotate, and the spiral fan blades 7 on the rotating shaft 6 rotate accordingly, so that outside air is drawn in from the fixed port 2 of the ventilation pipe 3.

[0037] Air circulation cooling: The intake air is propelled by the spiral fan blades 7 in the ventilation pipe 3, flows along the ventilation pipe 3 and is blown into the cement silo 1 through the connected air outlet pipe 4, so as to realize the circulation of air in the silo to remove heat and achieve the purpose of cooling.

[0038] Vibration trigger: When it is necessary to prevent cement from clumping, the fixed collar 14 on the rotating shaft 6 rotates with it, driving the flexible rubber impact plate 15 to periodically strike the vibrating metal rod 12 in the mounting hole 16 on the outer wall of the ventilation pipe 3.

[0039] Vibration transmission: When the vibrating metal rod 12 is struck, it generates vibration, which is transmitted to the cement material in the silo through the extension rod 13, keeping the cement in a loose state.

[0040] Dehumidification and moisture prevention: During the air circulation process, the dehumidifying and drying mesh plate 9 on the inner wall of the ventilation pipe 3 and the air outlet pipe 4 continuously absorbs moisture in the air, keeping the warehouse dry and preventing the cement from getting damp.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
