Description

Technical Field

[0001] The present application relates to the technical field of silo arch breaking, and in particular to an arch breaking device for a powder batching machine. Background Art

[0002] In the preparation process of asphalt, a powder batching machine is required. Usually, the bottom of the barrel of the powder batching machine is set in an inverted cone shape. The powder is discharged from the bottom of the barrel under the action of gravity for feeding. Since the cross-sectional area of ​​the barrel discharge port is much smaller than the cross-sectional area of ​​the storage part above the barrel, when the material falls to the discharge port position with a smaller cross-sectional area, the friction between the materials increases due to mutual squeezing, and the irregularly shaped materials mesh with each other to cause force balance, which often causes arching in the silo, making it impossible to discharge the material smoothly, affecting subsequent operations and production efficiency. There are different types of arches for different material characteristics. There are four main types of silo arches: compression arches, wedge arches, bonding and adhesion arches, and air pressure balance arches.

[0003] In view of the above-mentioned related technologies, the inventors believe that in order to ensure the smooth progress of the batching process and shorten the powder batching and processing time, it is necessary to propose an arch breaking device to achieve the effect of reducing the arching of materials in the batching barrel.

The air delivery branch pipe 23 is connected to a plurality of roots on the connecting ring pipe 22, and the end of the air delivery branch pipe 23 away from the connecting ring pipe 22 passes through the batching barrel 1 and extends to the inside of the discharge chamber 102. A plurality of air outlet holes are opened along the circumferential direction at one end of the air delivery branch pipe 23 located in the discharge chamber 102, and a flow-aiding air disc 24 is connected to one end of the air delivery branch pipe 23 located in the discharge chamber 102. The air disc 24 is in a disc shape, the edge of which is close to the inclined inner wall of the batching barrel 1, and the air outlet is connected to the inner cavity of the air disc 24. A check valve (not shown in the drawings) is provided in the gas delivery branch pipe 23.

[0033] Reference Figure 2 and Figure 3, the stirring assembly 3 is arranged on the batching barrel 1, and the stirring assembly 3 includes a first motor 31, a rotating plate 32, a second motor 33, a stirring rod 34, a transmission wheel 35 and a transmission belt 36.

The output shaft of the first motor 31 passes through the batching barrel 1 and is connected to the center position of the rotating plate 32. The stirring rod 34 is vertically rotatably connected to the bottom surface of the rotating plate 32. There is one stirring rod 34 at both ends of the length direction of the rotating plate 32, and a stirring blade 37 is arranged on the stirring rod 34.

The second motor 33 is arranged on the top surface of the rotating plate 32, and the output shaft of the second motor 33 is transmission-connected to the top of one of the stirring rods 34.

[0034] Reference Figure 2 , a spoiler block 7 is provided in the dispensing barrel 1, and the spoiler block 7 is provided in the discharging chamber 102. The spoiler block 7 is conical, and a connecting bracket 5 is fixedly connected to the bottom end of the spoiler block 7, and the connecting bracket 5 is arranged in a cross shape, and the connecting bracket 5 is fixedly connected to the inner wall of the dispensing barrel 1.

A sensor 4 is connected to the discharging end of the dispensing barrel 1, and the sensor 4 is electrically connected to the stirring component 3 and the air supply pump 21 through the control system.

[0035] Reference Figure 1 and Figure 2 When the material is discharged, the material in the batching barrel 1 is discharged from the discharge end at the bottom. When the material forms an arch in the discharge chamber 102, the material stops falling. The sensor 4 at the discharge end detects that the material stops flowing and sends a signal to the control system. The setting of the sensor 4 enables timely processing of the arched material, and the blowing and arch-breaking component 2 and the stirring component 3 do not need to be in a normally open state, which plays a role in energy saving and environmental protection. After receiving the signal from the control system, the air supply pump 21 starts to operate, and the air flow enters the discharge chamber 102 through the connecting pipe 25, the connecting ring pipe 22 and the air delivery branch pipe 23, and the material blocked at the discharge end is jet-assisted to flow so that it can flow smoothly. The air disc 24 disperses the linear air flow to the surroundings, and jets the material in all directions around the open end of the air delivery branch pipe 23 to help flow, which helps to accelerate the arch-breaking effect and efficiency of the material. Since a check valve is provided on the air delivery branch pipe 23, the possibility of the material in the batching barrel 1 entering the air delivery branch pipe 23 is reduced.

[0036] Reference Figure 2 and Figure 3At the same time, the first motor 31 starts to drive the rotating plate 32 to rotate, and the stirring rod 34 rotates with the rotating plate 32 and stirs the material in the storage chamber 101. The second motor 33 starts and drives the stirring rod 34 connected to it to rotate, and the transmission wheel 35 connected to the stirring rod 34 rotates. The other transmission wheel 35 and the stirring rod 34 rotate synchronously driven by the transmission belt 36, and the stirring blade 37 set on the stirring rod 34 stirs the material in the batching barrel 1. The setting of the stirring component 3 improves the flow degree of the material in the storage chamber 101, and further improves the material feeding efficiency.

[0037] Reference Figure 2 The conical disturbing fluid is arranged in the discharge chamber 102, which changes the pressure of the material in the batching barrel 1 on the silo wall and reduces the possibility of the material forming an arch during the material discharge process. At the same time, the vibration motor 6 drives the disturbing fluid to vibrate, so that the material in the batching barrel 1 cannot be in a completely static state. By combining the vibration flow aid with the jet flow aid, the arch breaking effect of the material is improved.

[0038] The implementation principle of an arch-breaking device for a powder batching machine in the embodiment of the present application is as follows: the sensor 4 detects that the material stops flowing and sends a signal to the control system. The air supply pump 21 receives the signal and starts to operate, and the airflow enters the discharge chamber 102 through the air branch pipe 23, and jets are used to assist the flow of the material blocked at the discharge end so that it can flow smoothly. The flow-aiding air disc 24 disperses the linear airflow to the surroundings, and jets are used to assist the flow of the material in all directions around the open end of the air branch pipe 23. At the same time, the first motor 31 drives the stirring rod 34 to rotate and stir the material. The second motor 33 starts and drives the stirring blades 37 to stir the material.

[0039] The setting of the disturbing fluid changes the pressure of the material in the batching barrel 1 on the silo wall, reducing the possibility of the material forming an arch during the material feeding process. At the same time, the vibration motor 6 drives the disturbing fluid to vibrate, and by combining the vibration flow aid with the jet flow aid, the arch breaking effect of the material is improved.
