Description

Technical Field

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

[0002] In the field of concrete preparation, concrete, as an engineering composite material made by mixing cement as the main binder with aggregates such as sand and stone, and adding an appropriate amount of water (admixtures or additives can be added as needed), is widely used in various civil engineering projects. Cement, with its excellent hydraulic properties, has become an indispensable component of concrete.

[0003] To meet the needs of concrete mixing plants, cement silos, as specialized bulk cement storage devices, have emerged. However, existing technologies present a problem in cement silos during cement storage: During long-term storage, cement's fluidity decreases, and changes in internal temperature and humidity cause it to solidify. This solidified cement affects its mixing uniformity with other raw materials during subsequent concrete production, leading to unstable concrete performance, insufficient strength, and abnormal setting times, directly impacting the quality of construction projects. Furthermore, the solidified cement forms hard lumps within the silo. These lumps not only occupy valuable storage space, reducing storage efficiency, but also may clog the discharge port during unloading, causing difficulties or even preventing unloading altogether. This severely impacts silo operation, increases equipment maintenance costs and downtime, and ultimately affects the production schedule of the concrete mixing plant.

[0004] Therefore, it is of great significance to provide a cement silo device that can uniformly mix and control humidity. Utility Model Content

Specific Implementation

[0034] Tank 1 has a discharge port 110 at the bottom and a radar level gauge 120, a feed channel 4, and an air outlet channel 5 fixedly connected to the top. A channel 8 is opened on one side of the tank 1. A bracket is fixedly connected to the bottom of the tank 1. The test end of the radar level gauge 120 extends into the top of the tank 1. It uses the principle of electromagnetic wave reflection to measure the cement level. It emits high-frequency electromagnetic waves into the cement silo. When the electromagnetic waves encounter the cement surface, they are reflected back. After receiving the reflected waves, the radar level gauge calculates the distance from the antenna to the cement surface based on the time difference between the emission and reception of the electromagnetic waves. Then, it calculates the capacity by combining the silo parameters, thereby obtaining the cement level.

[0035] The first stirring unit 2 includes a first stirring motor 22, a connecting rod 23 and stirring rods 24. The bottom end of the first stirring motor 22 is fixedly connected to the top end of the tank 1. The output end of the first stirring motor 22 is fixedly connected to one end of the connecting rod 23. The other end of the connecting rod 23 passes through the top end of the tank 1 and is located inside the tank 1. Multiple stirring rods 24 are fixed on the connecting rod 23.

[0036] Limiting and fixing rod 130, with both ends of the limiting and fixing rod 130 fixedly connected to the inner wall of tank 1;

[0037] The second mixing unit 6 includes a second mixing motor 61 and a rotating roller 62. The second mixing motor 61 is fixedly connected to the middle of the wall of the limiting and fixing rod 130. The output end of the second mixing motor 61 is fixedly connected to the top end of the rotating roller 62. The side wall of the rotating roller 62 is fixedly connected with a mixing plate 65 and a spiral blade 64 from the top end to the bottom end. The spiral blade 64 spirals around the side wall of the rotating roller 62. When the rotating roller 62 rotates, the mixing plate 65 and the spiral blade 64 will rotate accordingly to perform secondary mixing of the cement and ensure the uniformity of the cement.

[0038] Humidity regulating unit 7, the top of humidity regulating unit 7 passes through the channel 8 and is fixedly connected to the tank body 1.

[0039] According to the above technical solution, the present invention can achieve at least the following technical effects: By setting the feed channel 4 and the air outlet channel 5, cement is added and gas is discharged from the tank 1, respectively; Since cement is prone to sedimentation or uneven mixing at the bottom of the tank 1, a first stirring unit 2 and a second stirring unit 6 are set inside the tank 1 to perform secondary stirring of the cement. The spiral blades 64 on the outer surface of the rotating roller 62 rotate with the rotating roller 62 and can penetrate deep into the bottom of the cement. During the rotation, the cement at the bottom can be turned upwards, and at the same time, the stirring rod 24 stirs the cement in the upper part, so that the cement at the bottom and the cement in the upper part are fully mixed, preventing cement sedimentation and stratification and ensuring that the cement performance is consistent each time it is used; The humidity in the tank is monitored in real time by a capacitive humidity sensor, and the humidity regulator is activated to humidify the tank as needed, ensuring that the cement maintains appropriate humidity during storage and stirring. Appropriate humidity can effectively prevent the cement from generating dust or clumping due to excessive dryness, thereby improving the storage quality and stirring effect of the cement.

[0040] In this embodiment, the first stirring motor 22 is covered with a heat dissipation shell 21, and the outer surface of the heat dissipation shell 21 is provided with heat dissipation holes 211. The second stirring motor 61 is covered with a protective shell, and thermal grease is applied between the second stirring motor 61 and the protective shell.

[0041] According to the above technical solution, the present invention can achieve at least the following technical effects: by setting a heat dissipation shell 21, a relatively independent heat dissipation space is provided for the first stirring motor 22. The heat dissipation shell 21 has uniformly arranged heat dissipation holes 211 on its outer surface, so that the heat generated by the motor during operation can be dissipated in time, ensuring that the motor works within a suitable temperature range; the second stirring motor 61 is covered with a protective shell, which protects the motor and ensures that it can still operate stably inside the cement silo, preventing cement or dust from entering the motor and causing malfunctions or safety problems. At the same time, thermally conductive silicone grease is applied between the second stirring motor 61 and the protective shell. Since the thermally conductive silicone grease has good thermal conductivity, the heat generated by the motor can be transferred to the outside more quickly, thereby maintaining the normal and efficient operation of the motor.

[0043] According to the above technical solution, the present invention can achieve at least the following technical effects: the outer surface of the stirring rod 24 is covered with a wear-resistant rubber layer. The presence of the rubber layer can increase the friction between the stirring rod 24 and the cement. During stirring, it can better drive the cement particles to move, making the cement mixing more uniform and thorough, thereby improving the mixing effect.

[0044] In this embodiment, the stirring plate 65 has multiple through holes.

[0045] According to the above technical solution, the present invention can achieve at least the following technical effects: setting through holes is conducive to more uniform cement mixing and can reduce resistance when the mixing plate rotates at 65 degrees.

[0046] In this embodiment, the humidity control unit 7 includes a humidity regulator 71, a control pipe 72, and a capacitive humidity sensor 73. The capacitive humidity sensor 73 is fixedly connected to the top of the inner wall of the tank 1. One end of the control pipe 72 passes through the hole 8 and extends into the interior of the tank 1, and is fixedly connected to the tank 1. The other end is fixedly connected to the output port of the humidity regulator 71. A water inlet 711 is provided on the side wall of the humidity regulator 71. A control panel 74 is fixedly connected to the outer wall of the humidity regulator 71. The humidity regulator 71 and the capacitive humidity sensor 73 are electrically connected to the control panel 74, and the operation of the humidity regulator 71 and the humidity inside the tank 1 can be precisely controlled through the control panel 74.

[0047] According to the above technical solution, the present invention can achieve at least the following technical effects: both the humidity regulator 71 and the capacitive humidity sensor 73 are electrically connected to the control panel 74, allowing the operator to precisely control the operation of the humidity regulator 71 through the control panel 74 based on the data fed back by the capacitive humidity sensor 73; if the humidity inside the tank 1 is detected to be lower than the set value, the humidity regulator 71 can be turned on, and an appropriate amount of water vapor can be injected into the tank 1 through the regulating pipe 72 to achieve the required humidity standard; when the humidity inside the tank 1 is higher than the set value, the humidity regulator 71 can be turned on, and dry gas can be injected into the tank 1 through the regulating pipe 72 to achieve the required humidity standard, preventing the cement from generating dust due to excessive dryness or clumping due to excessive humidity.

[0048] In this embodiment, a feed pipe 9 is fixedly connected to the inlet of the feed channel 4, and a control valve 100 is fixedly connected to the feed pipe 9. An external feeding device is connected to the feed pipe 9. During feeding, the flow rate of cement can be controlled by the control valve 100 to ensure the accuracy and stability of feeding.

[0049] According to the above technical solution, the present invention can achieve at least the following technical effects: by setting a control valve 10 at the end of the feed pipe 9, the flow rate of cement entering the tank 1 can be precisely controlled, and the operator can adjust the flow rate of cement in a timely manner according to the actual production progress or the remaining capacity of the tank 1.

[0050] In this embodiment, a filter screen is provided in the air outlet channel 5, and the filter screen is made of glass fiber.

[0051] According to the above technical solution, the present invention can achieve at least the following technical effects: the filter screen is made of glass fiber material, which has the advantages of low resistance and high efficiency in intercepting fine particles, thus preventing dust in the cement silo from being discharged into the air and reducing air pollution.

[0052] In this embodiment, a lightning rod 3 is fixedly connected to the top of the tank 1. The lightning rod 3 is connected to a grounding electrode, which is buried underground to conduct lightning into the ground.

[0053] According to the above technical solution, the present invention can achieve at least the following technical effects: by installing a lightning rod 3 on the top of the tank 1, the safe operation of each component in the tank 1 during thunderstorms can be ensured, and the cement silo can be protected from lightning damage.

[0054] The working principle of this utility model of a cement silo device is as follows: First, cement enters the tank 1 through the feed pipe 9. The control valve 100 of the feed pipe 9 is used to regulate the flow rate of cement, ensuring that cement can enter the tank 1 stably and in appropriate amounts. After the cement enters the tank 1, the first stirring unit 2 starts to work. The first stirring motor 22 drives the connecting rod 23 and the stirring rod 24 to rotate, stirring the cement. When the first stirring unit 2 is stirring the cement or when the cement flows out from the discharge port 110, the second stirring unit 6 starts to work. The second stirring motor 61 drives the rotating roller 62 to rotate. The stirring plate 65 and the spiral blade 64 on the outer surface of the rotating roller 62 perform secondary stirring of the cement, thereby ensuring that the cement is fully stirred and uniformly mixed, avoiding cement clumping due to lack of flow. At this time, the radar level gauge 120 detects the depth of cement stored in the tank 1, allowing the user to clearly understand the amount of cement stored and avoid adding too much to the tank 1. During the process, the gas inside the tank 1 is discharged through the vent 5 to maintain stable air pressure inside the tank 1. The lightning rod 3 ensures the safe operation of the device during thunderstorms and prevents damage from lightning. In addition, the humidity control unit 7 performs humidification operation according to the humidity inside the tank 1. First, the capacitive humidity sensor 73 monitors the humidity inside the tank 1 in real time and feeds the data back to the control panel 74. When the humidity inside the tank 1 is lower than the set value, the control panel 74 will activate the humidity regulator 71 and inject an appropriate amount of water into the tank 1 through the regulating pipe 72 to increase the humidity inside the tank 1. This ensures that the cement maintains appropriate humidity during storage and mixing, and prevents the cement from becoming too dry and producing dust or clumping. When the user needs to use the cement, he / she opens the discharge port 110 at the bottom of the tank 1, and the cement can be discharged from the tank 1.
