Description

Technical Field

[0001] This utility model relates to the field of concrete-related equipment technology, and in particular to a dual-channel waiting silo for concrete raw materials. Background Technology

[0002] The main structure and function of the dual-channel concrete raw material waiting silo is that it has two silos for storing aggregates and powders respectively. In use, simply open the corresponding valve to transport the corresponding aggregates or powders from the waiting silo to the concrete mixing silo. Based on the flow rate of the aggregates or powders, the amount of aggregates or powders to be output can be estimated, making the mix ratio more suitable during concrete mixing and thus improving the quality of the concrete.

[0003] However, estimating the amount of aggregate or powder solely based on the output flow rate is difficult to control and can lead to significant errors. This is due to the influence of aggregate and powder particle size, as well as environmental factors such as the flow rate of damp or lumpy powder, which differs considerably from the flow rate of powder under normal conditions. Consequently, the concrete mix proportions may deviate. If the material feed rate is estimated solely based on the flow rate, the quality of the concrete will be affected by various factors over time.

[0004] Based on the above situation, it is necessary to design a dual-channel waiting silo for concrete raw materials to solve the above problems. Utility Model Content

[0005] This utility model provides a dual-channel waiting silo for concrete raw materials to solve the problem that the material metering output from the dual-channel waiting silo for concrete raw materials is not accurate due to various factors in the prior art.

[0008] Preferably, the driving component includes a gear ring connected to the outer wall of the cylindrical tube, a gear connected to the metering chamber, and a motor mounted on the metering chamber. The output end of the motor is connected to the gear, and the gear meshes with the gear ring.

[0009] Preferably, the bottom of the weighing chamber is a bucket-shaped structure with gradually decreasing internal space.

[0010] Preferably, a rotating shaft is rotatably connected at the output end of the outlet tube, one end of the rotating shaft extends into the interior of the weighing chamber, and a spiral blade is connected to the rotating shaft. A second motor is provided on the weighing chamber, and the output end of the second motor is connected to the rotating shaft.

[0011] Preferably, the output end of the conveying pipe is provided with an opening and closing component for controlling the flow rate of material output from the conveying pipe.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0025] Reference Figures 1-7 As shown, the concrete raw material dual-channel waiting silo includes a conveying pipe 2 connected to the two output ends of the waiting silo 1, a metering silo 3 connected to the output end of the conveying pipe 2, a cylindrical cylinder 9 rotatably connected inside the metering silo 3, and a weighing silo 11 set in the channel 10. Specifically, a discharge pipe 4 is connected to the output end of the metering silo 3, and the output end of the discharge pipe 4 is connected to a mixing tank 5 for concrete mixing and molding. The cylindrical cylinder 9 has at least two through channels 10, and the cylindrical cylinder 9 is driven to rotate by a driving component set on the metering silo 3. The output end of the weighing silo 11 is connected to an outlet pipe 13, and the output end of the outlet pipe 13 and the input end of the weighing silo 11 are respectively movably connected to the input end of the discharge pipe 4 and the output end of the conveying pipe 2. The cylindrical cylinder 9 is equipped with a pressure sensor 12 for weighing the weighing silo 11.

[0026] In operation, the material in the hopper 1 is conveyed along the connected conveying pipe 2. When it reaches the weighing chamber 3, because one of the channels 10 inside the cylindrical cylinder 9 is connected to the output end of the conveying pipe 2, the material falls into the weighing chamber 11 located in that channel 10. Then, the pressure sensor 12 on the cylindrical cylinder 9 senses the weight of the material gradually increasing in the weighing chamber 11. When the required weight of material is reached, the conveying pipe 2 stops outputting material. Then, the driving component drives the cylindrical cylinder 9 to rotate, causing the weighing chamber containing the material inside to rotate. Rotate 11 to the position of the output end of the discharge pipe 4, so that the output end of the outlet pipe 13 on the weighing chamber 11 is connected to the input end of the discharge pipe 4. Then, the material in the weighing chamber 11 is introduced into the discharge pipe 4 and discharged through the discharge pipe 4. At the same time, another empty weighing chamber 11 will take over the position of the weighing chamber 11 that was previously filled with material and start to receive the material output from the conveying pipe 2. Two or more weighing chambers 11 are used in cooperation with each other to weigh the conveyed material without affecting the concrete production efficiency, which greatly increases the accuracy of concrete batching.

[0027] To ensure that the various structures in this device can be linked together and reduce the number of manual operation steps, the device structure also includes a controller 6 and a pressure sensor 12 to weigh the material received in the weighing chamber 11 and generate corresponding weight information. This weight signal is transmitted to the controller 6, which compares it with the set value. After the material in the weighing chamber 11 reaches the required weight, the controller 6 will promptly close the conveying pipe 2 and stop its continued conveying. Then, the controller 6 controls the motor 16 to drive the cylindrical cylinder 9 to rotate. Next, the outlet pipe 13 on the weighing chamber 11 is connected to the input end of the discharge pipe 4, and then the material in the weighing chamber 11 is discharged and sent into the discharge pipe 4, and finally discharged.

[0028] In this invention, the material storage silo 1 mentioned is existing technology, and the material storage silo 1 includes an aggregate storage silo 7, a powder storage silo 8, and conveying pipes 2 connected to the aggregate storage silo 7 and the powder storage silo 8 respectively. That is, the conveying pipes 2 in the device of this invention. In the prior art, the output end of the conveying pipe 2 is mainly connected to a mixing chamber for mixing the material. In this invention, it is output to the mixing chamber through the discharge pipe 4. The concrete will be mixed and produced in the mixing chamber. The above structure and technical solution are all existing technology and will not be described in detail. However, this invention innovates and improves on the existing structure to solve the problem that the material metering output from the dual-channel material storage silo of concrete raw materials is not accurate enough due to various factors in the prior art.

[0029] Furthermore, the driving components include a gear ring 14 connected to the outer wall of the cylindrical tube 9, a gear 15 connected to the metering chamber 3, and a motor 16 mounted on the metering chamber 3. The output end of the motor 16 is connected to the gear 15, and the gear 15 meshes with the gear ring 14. In use, the motor 16 is started to drive the gear 15 to rotate, which in turn drives the gear ring 14 to rotate, and the gear ring 14 drives the cylindrical tube 9 to rotate synchronously.

[0030] To facilitate the smooth flow of materials inside the weighing bin 11 through the outlet pipe 13, the bottom of the weighing bin 11 is a bucket-shaped structure with gradually decreasing internal space, which facilitates the sliding and output of materials.

[0031] Furthermore, to prevent the material from piling up inside the weighing chamber 11, which would hinder the output of the material from the outlet pipe 13, a rotating shaft 17 is rotatably connected at the output end of the outlet pipe 13. One end of the rotating shaft 17 extends into the interior of the weighing chamber 11, and a spiral blade 18 is connected to the rotating shaft 17. A second motor 19 is installed on the weighing chamber 11, and the output end of the second motor 19 is connected to the rotating shaft 17. The second motor 19 is equipped with a protective cover to prevent it from being impacted or contaminated. During use, when the weighing chamber 11 receives... After a certain weight of material is received, the drive unit will drive the cylindrical cylinder 9 to rotate, so that the outlet pipe 13 on the weighing bin 11 connects with the input end of the discharge pipe 4. Then, the second motor 19 is started, and the second motor 19 drives the rotating shaft 17 to rotate, which in turn drives the spiral blade 18 to rotate, so that the material in the weighing bin 11 will be sent out, preventing the problem of material accumulation and poor material discharge in the weighing bin 11. Secondly, when the spiral blade 18 does not rotate, its spiral structure also helps to prevent the material from being output from the outlet pipe 13.

[0032] Furthermore, in order to facilitate the opening and closing of the conveying pipe 2 by the controller 6, an opening and closing component is provided at the output end of the conveying pipe 2 to control the flow rate of the material output by the conveying pipe 2. The controller 6 will control the operation of the opening and closing component according to the weight change of the material in the weighing bin 11, thereby gradually closing the conveying pipe 2 and stopping it from conveying material.

[0033] The opening and closing assembly includes a connecting box 20 connected to the output end of the conveying pipe 2, two slide rails 21 symmetrically arranged on the connecting box 20, a gate 222 slidably connected within the slide rails 21, and a telescopic rod 23 that drives the gate 222 to slide. The two gates 222 extend into the connecting box 20 at one end, and the movable end of the telescopic rod 23 is connected to the end of the gate 222 away from the connecting box 20. In use, the controller 6 controls the telescopic rod 23 to operate, and then the movable end of the telescopic rod 23 controls the gate 222 connected to it to slide, moving away from the connecting box 20 between the two gates 222. When sliding in the internal direction, the material inside the conveying pipe 2 will slide down under the action of gravity and be output from the output end of the conveying pipe 2. When sliding between the two gates 222 in the direction of the connection box 20, the output end of the conveying pipe 2 will be closed and the material output will stop. When the output end of the conveying pipe 2 is closed, the two gates 222 gradually approach each other under the action of their respective connected telescopic rods 23, and the distance between them gradually decreases, thereby gradually reducing the flow rate of the material flowing out between them. This facilitates the pressure sensor 12 to weigh the weighing chamber 11, making the increase in the weight of the material inside the weighing chamber 11 more accurate.

[0034] To ensure that the gate 222 is less impacted by materials during use and to facilitate the sliding of materials on the gate 222, the two gates 222 are arranged in a V-shape on the connecting box 20, and the two gates 222 move linearly along the slide 21 respectively. The gates 222 are arranged in an inclined direction, so that when the material impacts the gate 222, the impact force is dispersed. Secondly, it also allows the material to be output from the output end of the conveying pipe 2 along the inclined gate 222.
