Description

Technical Field

[0001] This utility model relates to the field of weighing and measurement technology, specifically a silo weight monitoring device. Background Technology

[0002] In a broad sense, a reactor is a container that undergoes physical or chemical reactions. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. The reactor's silo is usually rigidly connected to the feed pipe and the reactor. The conventional monitoring method is to detect and control the total amount of material being conveyed, thereby detecting the weight of the material in the silo. The data obtained by this method often has a large error due to factors such as the length of the conveying pipeline, resulting in inaccurate detection results. To solve the above problems, those skilled in the art have proposed using a flexible connection to connect the feed pipe and the reactor. This allows the use of a pressure weighing device to weigh the silo, resulting in relatively accurate detection results. However, this structural method requires the pressure weighing device to bear the weight continuously, which means it is constantly being triggered, significantly reducing its service life. In addition, if an accident occurs that causes the pressure weighing device to be damaged, the silo may tip over.

[0003] Therefore, designing a device that improves safety and extends service life is the problem the inventors are trying to solve. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a silo weight monitoring device that can improve the safety factor and extend the service life.

[0005] The technical solution adopted by this utility model device is: a silo weight monitoring device, including a reinforcing plate, the reinforcing plate is set on the outer wall of the reactor silo, the reactor silo is set inside the through hole opened on the platform, the reinforcing plate is connected to a support structure, the lower end of the support structure is provided with a pressure-bearing weighing device, the bottom of the pressure-bearing weighing device is provided with a base, the end face of the base and the side of the laminated side mounting device are provided with a limit post, the side of the base and the lower part of the support structure are provided with an electric jack, and the side of the reactor silo and the end face of the platform are provided with an arc-shaped baffle.

[0006] Furthermore, both the pressure-bearing weighing device and the electric jack are connected to a controller, and the controller is connected to a display.

[0007] Furthermore, a wire groove is connected to the side wall of the arc-shaped baffle.

[0008] Furthermore, the arc-shaped baffle is disposed between two adjacent support structures.

[0009] Furthermore, the number of reinforcing plates is four, and they are evenly distributed on the circumferential surface of the reactor hopper.

[0010] Furthermore, when the electric jack is retracted to its lowest position, its top height is lower than the top height of the limiting post.

[0011] Furthermore, the top height of the limiting column is lower than the top height of the pressure-bearing weighing device at its minimum retracted position.

[0012] The beneficial effects of this utility model device are:

[0013] 1. This utility model uses a limiting column and an electric jack as double insurance to meet the support needs of the silo in case of emergencies. At the same time, by utilizing the characteristics of the electric jack, the silo can be lifted a certain distance when real-time weight monitoring is not required, so that the pressure weighing device is freed from pressure and achieves the functions of improving the safety factor and extending the service life.

[0016] The present invention will be further described below with reference to specific embodiments. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0017] Example 1: See Figure 1This is a structural view of the present invention, a silo weight monitoring device, including four reinforcing plates 2 evenly distributed on the circumference of a reactor silo 1. The reinforcing plates 2 are located on the outer wall of the reactor silo 1, which is situated inside a through-hole on a platform 10. A reactor is positioned below the platform 10. The lower end of the reactor silo 1 is connected to the reactor inlet via a flexible connection, and the inlet end of the reactor silo 1 is connected to a material conveying pipe via a flexible connection. This connection method minimizes the impact of the input and output connection structure on the weighing process. The reinforcing plates 2 are connected to a supporting structure 3. The support structure 3 includes a support plate and two parallel reinforcing ribs. A pressure-bearing weighing device 4 is installed at the lower end of the support structure 3. The pressure-bearing weighing device 4 contacts the support structure 3 through a top block, thereby measuring the real-time weight of the reactor silo 1. A base 7 is installed at the bottom of the pressure-bearing weighing device 4. The base 7 is connected to the platform 10 by bolts. A limit post 5 is installed on the end face of the base 7 and the side of the lamination side mounting device. The top height of the limit post 5 is lower than the top height of the pressure-bearing weighing device 4 at its minimum contraction position. In case of emergencies, it can replace the pressure-bearing weighing device 4 to provide emergency support for the reactor silo 1 and avoid safety accidents.

[0018] An electric jack 6 is installed on the side of the base 7 and below the support structure 3. The pressure weighing device 4 and the electric jack 6 are both connected to a controller. The controller is connected to a display. The operator can monitor the change in weight of the reactor silo 1 in real time through the controller and the display. Then, by subtracting the weight of the device through the algorithm, the weight of the material in the reactor silo 1 can be obtained more accurately.

[0019] Because there is a gap between the edge of the through hole in the platform 10 and the reactor hopper 1, in order to prevent the connecting wires of the pressure weighing device 4 and the electric jack 6 from entering the gap and affecting the accuracy of the weighing data or causing damage, an arc-shaped baffle 8 is further provided on the side of the reactor hopper 1 and the end face of the platform 10.

[0020] To better arrange the wires and organize their paths, a wire groove 9 is connected to the side wall of the arc-shaped baffle 8, and the aforementioned wires are placed in the wire groove 9.

[0021] Four arc-shaped baffles 8 are installed between two adjacent support structures 3.

[0022] When the electric jack 6 is retracted to its lowest position, its top height is lower than the top height of the limit post 5. When the electric jack 6 is retracted to its lowest position, it will not affect the daily use of the device as a whole.

[0023] When it is necessary to monitor the weight of the reactor silo 1, the weight of the reactor silo 1 is measured by the pressure-bearing weighing device 4. When it is not necessary to monitor the weight of the reactor silo 1 in real time, such as during shutdown maintenance, the controller can control four electric jacks 6 to lift the support structure 3 synchronously, thereby making the support structure 3 detach from the contact state with the pressure-bearing weighing device 4, and the electric jacks 6 can maintain the lifting state for a long time.

[0024] This utility model uses a limiting column 5 and an electric jack 6 as double insurance to meet the support needs of the silo in case of emergencies. At the same time, by utilizing the characteristics of the electric jack 6, the silo can be lifted a certain distance when real-time weight monitoring is not required, so that the pressure weighing device 4 can be freed from pressure, thereby improving the safety factor and extending the service life.
