Description

Technical Field

[0001] The utility model relates to the technical field of feeding pipelines, in particular to an automatic dredging material pipe for blockage of a large tank. Background Art

[0002] In the prior art, a blower is usually used as a power source to push powder to move inside a pipeline, so that it can be transported to a designated silo.

[0003] However, in the actual application process, due to the relatively long length of the pipeline, the powder is very likely to be blocked at a certain place in the pipeline during transportation, which not only affects the normal transportation of the powder, but also may have an adverse impact on the entire production process. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an automatic dredging material pipe for blockage of a large tank, which can dredge the blocked material in the feeding pipe, thereby effectively preventing the material pipe from being blocked and improving the efficiency and reliability of material transportation.

[0005] The utility model is realized by the following technical solutions: an automatic dredging material pipe for blockage of a large tank is provided, which includes a feeding pipe and a blower installed on the feeding pipe. A plurality of pressure sensors are axially installed in the feeding pipe, and all of the plurality of pressure sensors are located between the feeding port and the discharging port of the feeding pipe. A discharging pipe fixedly connected to the bottom of the feeding pipe is arranged between two adjacent pressure sensors, and a sluice valve is installed on the discharging pipe. The sluice valve is electrically connected to two adjacent pressure sensors.

[0006] During the use of the utility model, a feeding pipe and a blower installed on the feeding pipe are provided, and a number of pressure sensors are axially installed in the feeding pipe. The pressure sensors are all located between the feeding port and the discharging port of the feeding pipe. An outlet pipe fixedly connected to the bottom of the feeding pipe is provided between two adjacent pressure sensors. A sluice valve is installed on the outlet pipe, and the sluice valve is electrically connected to two adjacent pressure sensors. When the device is in use, the feeding port and the discharging port of the feeding pipe need to be communicated with a feeding device and a silo respectively first, and then the feeding device is used to convey materials into the feeding pipe, and the materials are blown into the silo by the blower. If the feeding pipe between two adjacent pressure sensors is blocked during the use of the device, and the blower is still transporting the materials in the feeding pipe, it will cause the pressure in the feeding pipe on the side of the feeding device towards the blocked material to rise, while the pressure in the feeding pipe on the side of the silo towards the blocked material is still normal. The pressure sensor located on the side of the blocked material towards the feeding device and adjacent to the blocked material detects that the pressure has risen to a certain value, while the pressure sensor located on the side of the blocked material towards the silo and adjacent to the blocked material detects that the pressure is still normal, then an electrical signal will be sent to the sluice valve to control the sluice valve on the outlet pipe between the two pressure sensors to open, so that the blocked material or part of the blocked material can fall into the outlet pipe between the two pressure sensors and be discharged to the outside through the outlet pipe, so as to dredge the blocked material in the feeding pipe between two adjacent pressure sensors, thereby effectively preventing the material pipe from being blocked and improving the efficiency and reliability of material transportation. When the pressure sensor located on the side of the blocked material towards the feeding device and adjacent to the blocked material detects that the pressure returns to the normal value, while the pressure sensor located on the side of the blocked material towards the silo and adjacent to the blocked material detects that the pressure is still normal, an electrical signal will be sent to the sluice valve again to control the sluice valve on the outlet pipe between the two pressure sensors to close, so that the blower can continue to push the materials in the feeding pipe into the silo.

[0007] Preferably, the feeding pipe includes a horizontally arranged horizontal pipe and a vertically arranged vertical pipe installed on the top of the horizontal pipe. A connecting pipe is fixedly connected to the output end of the horizontal pipe. The first outlet pipe and the second outlet pipe are both arranged on the horizontal pipe. The blower is arranged at the input end of the horizontal pipe. The feeding pipe includes a horizontally arranged horizontal pipe and a vertically arranged vertical pipe installed on the top of the horizontal pipe. A connecting pipe is fixedly connected to the output end of the horizontal pipe. The first outlet pipe and the second outlet pipe are both arranged on the horizontal pipe. The blower is arranged at the input end of the horizontal pipe. The horizontal pipe is communicated with the feeding device and the silo respectively through the vertical pipe and the connecting pipe, which can not only optimize the material flow path, but also improve the use efficiency of the blower.

[0008] Preferably, the blower is axially aligned with the horizontal pipe. By axially aligning the blower with the horizontal pipe, the air supply efficiency of the blower can be optimized, making the movement of materials in the horizontal pipe smoother and reducing the risk of blockage caused by uneven wind force.

[0009] Preferably, the pressure sensor is installed at the top of the inner side wall of the horizontal pipe. By installing the pressure sensor at the top of the inner side wall of the horizontal pipe, it is possible to prevent the material from falling on the pressure sensor during the conveying process, thereby avoiding the material from affecting the detection of the pressure change in the horizontal pipe by the pressure sensor, and thus quickly responding when blockage occurs and promptly starting the plug valve for dredging.

[0010] Preferably, the horizontal pipe, the vertical pipe and the connecting pipe are provided as an integral structure. By setting the horizontal pipe, the vertical pipe and the connecting pipe as an integral structure, the stability between the horizontal pipe, the vertical pipe and the connecting pipe during the use of the device can be improved.

[0011] The beneficial effects of the present utility model are as follows: By providing a feeding pipe and a fan installed on the feeding pipe, and axially installing a plurality of pressure sensors in the feeding pipe, all the plurality of pressure sensors are located between the feeding port and the discharging port of the feeding pipe, and a discharging pipe fixedly connected to the bottom of the feeding pipe is provided between adjacent two pressure sensors, a plug valve is installed on the discharging pipe, and the plug valve is electrically connected to the adjacent two pressure sensors. When the device is in use, it is necessary to first conduct the feeding port and the discharging port of the feeding pipe with a feeding device and a silo respectively, and then convey the material into the feeding pipe through the feeding device, and make the material enter the silo under the blowing of the fan. If during the use of the device, the feeding pipe between adjacent two pressure sensors is blocked, and the fan is still transporting the material in the feeding pipe, it will cause the pressure in the feeding pipe on the side of the blockage towards the feeding device to rise, while the pressure in the feeding pipe on the side of the blockage towards the silo is still normal. The pressure sensor located on the side of the blockage towards the feeding device and adjacent to the blockage detects that the pressure rises to a certain value, while the pressure sensor located on the side of the blockage towards the silo and adjacent to the blockage detects that the pressure is still normal, then an electrical signal will be sent to the plug valve to control the opening of the plug valve on the discharging pipe between the two pressure sensors, so that the blocked material or part of the blocked material can fall into the discharging pipe between the two pressure sensors and be discharged to the outside through the discharging pipe, thereby dredging the blockage of the feeding pipe between adjacent two pressure sensors, and effectively preventing the material pipe from being blocked, improving the efficiency and reliability of material conveying. When the pressure sensor located on the side of the blockage towards the feeding device and adjacent to the blockage detects that the pressure returns to the normal value, while the pressure sensor located on the side of the blockage towards the silo and adjacent to the blockage detects that the pressure is still normal, an electrical signal will be sent to the plug valve again to control the closing of the plug valve on the discharging pipe between the two pressure sensors, so that the fan can continue to push the material in the feeding pipe into the silo.

[0017] To clearly illustrate the technical features of this solution, the following will elaborate on this solution through specific implementation modes.

[0018] As Figures 1-3 shown, the automatic blockage dredging material pipe of the large tank of the present utility model includes a feeding pipe and a fan 2 installed on the feeding pipe. A plurality of pressure sensors 8 are axially installed in the feeding pipe. All of the plurality of pressure sensors 8 are located between the feeding port and the discharging port of the feeding pipe. A discharge pipe 3 fixedly connected to the bottom of the feeding pipe is arranged between two adjacent pressure sensors 8. A slide valve 9 is installed on the discharge pipe 3. The slide valve 9 is electrically connected to two adjacent pressure sensors 8.

[0019] The feeding pipe includes a horizontally arranged horizontal pipe 5 and a vertically arranged vertical pipe 4 installed on the top of the horizontal pipe 5. The output end of the horizontal pipe 5 is fixedly connected with a connecting pipe 6. The first discharge pipe 3 and the second discharge pipe 3 are both arranged on the horizontal pipe 5. The fan 2 is arranged at the input end of the horizontal pipe 5. The horizontal pipe 5 is respectively communicated with the feeding device 1 and the silo 7 through the vertical pipe 4 and the connecting pipe 6. In this way, not only can the material flow path be optimized, but also the use efficiency of the fan 2 can be improved. By aligning the fan 2 and the horizontal pipe 5 axially, the air supply efficiency of the fan 2 can be optimized, making the movement of the material in the horizontal pipe 5 smoother and reducing the risk of blockage caused by uneven wind force. By installing the pressure sensor 8 on the top of the inner side wall of the horizontal pipe 5, it can be avoided that the material falls on the pressure sensor 8 during the conveying process, thereby avoiding the material from affecting the detection of the pressure change in the horizontal pipe 5 by the pressure sensor 8, so as to quickly respond when blockage occurs and timely start the slide valve 9 for dredging. By setting the horizontal pipe 5, the vertical pipe 4 and the connecting pipe 6 as an integral structure, the stability between the horizontal pipe 5, the vertical pipe 4 and the connecting pipe 6 during the use of the device can be improved.

[0020] Combined with the attached Figures 1-3It can be seen that the usage method of the present utility model is as follows: First, it is necessary to make the horizontal pipe 5 communicate with the feeding device 1 and the silo 7 respectively through the vertical pipe 4 and the connecting pipe 6. Then, the feeding device 1 is used to convey materials into the horizontal pipe 5, so that the materials enter the horizontal pipe 5 through the vertical pipe 4, and the materials in the horizontal pipe 5 enter the silo 7 through the connecting pipe 6 under the blowing of the fan 2. If the horizontal pipe 5 between two adjacent pressure sensors 8 becomes blocked during the use of the device, and the fan 2 is still transporting the materials in the feeding pipe, it will cause the pressure in the horizontal pipe 5 on the side towards the feeding device 1 of the blockage to rise, while the pressure in the horizontal pipe 5 on the side towards the silo 7 of the blockage remains normal. The pressure sensor 8 located on the side towards the feeding device 1 of the blockage and adjacent to the blockage detects that the pressure rises to a certain value, while the pressure sensor 8 located on the side towards the silo 7 of the blockage and adjacent to the blockage detects that the pressure remains normal, then an electrical signal will be sent to the plug valve 9 to control the plug valve 9 on the discharge pipe 3 between the two pressure sensors 8 to open, so that the blockage or part of the blockage can fall into the discharge pipe 3 between the two pressure sensors 8 and be discharged to the outside, thereby dredging the blockage of the horizontal pipe 5 between two adjacent pressure sensors 8, effectively preventing the material pipe from being blocked, and improving the efficiency and reliability of material transportation. When the pressure sensor 8 located on the side towards the feeding device 1 of the blockage and adjacent to the blockage detects that the pressure returns to the normal value, and the pressure sensor 8 located on the side towards the silo 7 of the blockage and adjacent to the blockage also detects that the pressure remains normal, an electrical signal will be sent to the plug valve 9 again to control the plug valve 9 in the discharge pipe 3 between the two pressure sensors 8 to close, so that the fan 2 continues to push the materials in the horizontal pipe 5 into the silo 7.
