Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial automation control technology, and in particular to an ash unloading control device for preventing material blockage. Background Technology
[0002] In the industrial production process, the ash discharge control system undertakes the key task of handling various dust and particulate matter emissions. Its stable operation is crucial to ensuring production continuity and environmental compliance. As the core component of the industrial dust removal system, the ash discharge control system realizes the timed collection, compression, transfer and centralized treatment of dust, effectively preventing dust accumulation and secondary dust generation inside the equipment.
[0003] Current ash unloading control devices generally adopt a relatively simple and direct control logic, that is, after the upstream equipment starts, the downstream equipment responds and starts operating instantly. However, at this time, the upstream equipment may not have entered a stable material conveying state, causing a large amount of material to rush into the downstream equipment in a short period of time, which can easily lead to material accumulation. At the same time, the unstable airflow in the initial stage of startup will also have a negative impact on material conveying, further increasing the possibility of blockage in the downstream equipment. Once the downstream equipment is blocked, it will not only interrupt the normal ash unloading process, but may also cause irreversible damage to the equipment itself, such as motor overload and burnout, pipe wear and rupture, etc., which will seriously affect production efficiency and significantly increase maintenance costs.
[0004] Therefore, in response to the problem that ash blockage is prone to occur when the upstream and downstream equipment of the existing ash unloading control device operates synchronously, an anti-blockage ash unloading control device can be designed. By staggered and delayed operation, the material enters the downstream equipment in a smoother manner, allowing the motor, transmission device, etc. to gradually reach a stable operating state, avoiding blockage caused by uneven instantaneous load, poor material connection, or mechanical conflict, thereby effectively extending the service life of the device. Utility Model Content
[0005] In order to overcome the problem that most ash unloading control devices may not have entered a stable material conveying state upstream, resulting in a large amount of material rushing into the downstream equipment in a short period of time, and the downstream equipment may be blocked due to improper start-up timing, this utility model is proposed.
[0006] The technical solution of this utility model is as follows: an anti-blocking ash discharge control device, comprising an upstream equipment body, a fixed frame, a main control board, a discharge hopper, a time relay, a first discharge pipe, a first ash discharge valve, a first conveying auger, a buffer bin, a third discharge pipe, a second ash discharge valve, a second conveying auger, and an ultrasonic sensor. A fixed frame is provided on the outside of the upstream equipment body, a main control board is provided on the outside of the fixed frame, and a time relay is provided on the outside of the fixed frame. A first discharge pipe is provided at the bottom of the upstream equipment body, a first ash discharge valve is provided on the outside of the first discharge pipe, a first conveying auger is connected through to the bottom of the first discharge pipe, a buffer bin is connected through to the bottom of the first conveying auger, a third discharge pipe is provided at the bottom of the buffer bin, a second ash discharge valve is provided on the outside of the third discharge pipe, a second conveying auger is connected through to the bottom of the third discharge pipe, a discharge hopper is provided at the bottom of the second conveying auger, and an ultrasonic sensor is provided at the bottom of the discharge hopper.
[0007] Preferably, the upstream equipment body is fixedly supported by a fixed frame, and the operation of the upstream equipment body is controlled by the main control board. After the upstream equipment body starts running, the first ash discharge valve is delayed to start via a time relay. The delayed start of the first ash discharge valve opens the first discharge pipe, and the ash material in the upstream equipment body is transported to the first conveying auger through the first discharge pipe. The first conveying auger transports the ash material in an orderly manner to the buffer bin. The opening and closing of the third discharge pipe is flexibly controlled by the second ash discharge valve, and the ash material in the buffer bin is transported to the second conveying auger through the third discharge pipe. The ash material is transported to the discharge hopper through the second conveying auger, and discharged through the discharge hopper. The equipment below the discharge hopper is sensed by an ultrasonic sensor, thereby enabling the material to enter the downstream equipment in a smoother manner, allowing the motor, transmission device, etc. to gradually reach a stable operating state. This avoids blockage caused by uneven instantaneous load, poor material connection, or mechanical conflict, and extends the service life of the device.
[0008] Preferably, the main control board is electrically connected to the upstream equipment body and the time relay, the time relay is electrically connected to the first ash discharge valve, and the ultrasonic sensor is electrically connected to the second ash discharge valve.
[0009] Preferably, a first motor is installed at the top of the first conveying auger, and the first motor is electrically connected to a time relay.
[0010] Preferably, the output end of the first motor is connected to the drive shaft of the first conveying auger, and a second discharge pipe is provided through the bottom end of the first conveying auger, with the bottom end of the second discharge pipe being connected through the buffer chamber.
[0011] Preferably, a pressure sensor is installed at the bottom inner side of the buffer chamber, and the pressure sensor is electrically connected to the first ash discharge valve and the first motor.
[0012] Preferably, a second motor is provided at the top of the second conveying auger, the second motor is electrically connected to the second ash discharge valve, and the output end of the second motor is connected to the drive shaft of the second conveying auger.
[0013] Preferably, multiple sets of support rods are provided at the four corners of the bottom of the fixed frame, and reinforcing ribs are symmetrically arranged between the two sets of support rods. The reinforcing ribs are arranged in an X shape. Two sets of support rods are symmetrically arranged at the bottom of the buffer chamber and the second conveying auger.
[0014] The beneficial effects of this utility model are:
[0015] During ash discharge, the main control board on the fixed frame controls the operation of the upstream equipment. After the upstream equipment starts operating, a time relay controls the first ash discharge valve to start with a delay. This delay controls the opening of the first discharge pipe, which then transports the ash material from the upstream equipment to the first conveying auger. The first conveying auger then transports the ash material orderly to the buffer hopper. The second ash discharge valve flexibly controls the opening and closing of the third discharge pipe, which then transports the ash material from the buffer hopper to the second conveying auger. The second conveying auger then transports the ash material to the discharge hopper, where it is discharged. An ultrasonic sensor senses the equipment below the discharge hopper and flexibly controls the discharge status of the buffer hopper. This addresses the problem that most upstream equipment may not yet be in a stable material conveying state, causing a large amount of material to rush into the downstream equipment in a short period of time, which can easily lead to material accumulation. This extends the service life of the equipment. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Please see Figure 1 and Figure 4 This utility model provides an embodiment: an anti-clogging ash discharge control device, including an upstream equipment body 1, a fixing frame 2, a main control board 3, a discharge hopper 12, a time relay 4, a first discharge pipe 5, a first ash discharge valve 6, a first conveying auger 7, a buffer bin 8, a third discharge pipe 9, a second ash discharge valve 10, a second conveying auger 11, and an ultrasonic sensor 13. The fixing frame 2 is located on the outer side of the upstream equipment body 1, the main control board 3 is located on the outer side of the fixing frame 2, and the time relay 4 is located on the outer side of the fixing frame 2. The main control board 3 is electrically connected to the upstream equipment body 1 and the time relay 4. The bottom end of the upstream equipment body 1 is provided with... There is a first discharge pipe 5, and a first ash discharge valve 6 is installed on the outside of the first discharge pipe 5. A time relay 4 is electrically connected to the first ash discharge valve 6. A first conveying auger 7 is connected through the bottom end of the first discharge pipe 5. A buffer chamber 8 is connected through the bottom end of the first conveying auger 7. A third discharge pipe 9 is installed at the bottom end of the buffer chamber 8. A second ash discharge valve 10 is installed on the outside of the third discharge pipe 9. A second conveying auger 11 is connected through the bottom end of the third discharge pipe 9. A discharge hopper 12 is installed at the bottom end of the second conveying auger 11. An ultrasonic sensor 13 is installed at the bottom end of the discharge hopper 12. The ultrasonic sensor 13 is electrically connected to the second ash discharge valve 10.
[0023] Please see Figure 2 and Figure 3 In this embodiment, a first motor 701 is provided at the top of the first conveying auger 7. The first motor 701 is electrically connected to the time relay 4. The output end of the first motor 701 is connected to the drive shaft of the first conveying auger 7. A second discharge pipe 702 is provided through the bottom end of the first conveying auger 7. The bottom end of the second discharge pipe 702 is connected through the buffer bin 8. The first ash discharge valve 6 is controlled to start after a delay by the time relay 4. At this time, the first motor 701 runs synchronously. The first motor 701 drives the first conveying auger 7 to run. The ash material is conveyed to the second discharge pipe 702 through the first conveying auger 7. The ash material is then conveyed to the buffer bin 8 for buffer storage through the second discharge pipe 702.
[0024] A pressure sensor 801 is installed at the bottom inner side of the buffer chamber 8. The pressure sensor 801 is electrically connected to the first ash discharge valve 6 and the first motor 701. The pressure sensor 801 senses the amount of ash in the buffer chamber 8. When the amount of ash exceeds the set value, the first ash discharge valve 6 and the first motor 701 are controlled to stop running to avoid ash accumulation and blockage.
[0025] Please see Figure 1 and Figure 2 In this embodiment, a second motor 1101 is provided at the top of the second conveying auger 11. The second motor 1101 is electrically connected to the second ash discharge valve 10. The output end of the second motor 1101 is connected to the drive shaft of the second conveying auger 11. When the second ash discharge valve 10 is opened, the second motor 1101 runs synchronously. The second motor 1101 controls the operation of the second conveying auger 11, and the ash material in the buffer bin 8 is discharged by the second conveying auger 11. Multiple sets of support rods 201 are provided at the four corners of the bottom end of the fixing frame 2. Reinforcing ribs 202 are symmetrically arranged between two sets of support rods 201. The reinforcing ribs 202 are arranged in an X shape. Two sets of support rods 201 are symmetrically arranged at the bottom end of the buffer bin 8 and the second conveying auger 11. The support rods 201 support the entire fixing device, and the reinforcing ribs 202 enhance the overall stability of the device and ensure that the device is placed stably.
[0026] During ash discharge, the support device is stabilized by the support rod 201 and the reinforcing rib 202. The main control board 3 on the fixed frame 2 controls the operation of the upstream equipment body 1. After the upstream equipment body 1 is running, the first ash discharge valve 6 is delayed to start by the time relay 4. The delay controls the first ash discharge valve 6 to open the first discharge pipe 5.
[0027] At the same time, the first motor 701 controls the first conveying auger 7 to operate synchronously, and the ash material in the upstream equipment body 1 is conveyed to the first conveying auger 7 through the first discharge pipe 5. The ash material is then conveyed to the buffer bin 8 in an orderly manner through the second discharge pipe 702 using the first conveying auger 7.
[0028] Subsequently, the waste ash recycling equipment is placed under the discharge hopper 12. The ultrasonic sensor 13 senses that the equipment is in place under the discharge hopper 12, thereby controlling the second ash discharge valve 10 to open the third discharge pipe 9. At the same time, the second motor 1101 controls the second conveying auger 11 to run synchronously. The ash material in the buffer bin 8 is transported to the second conveying auger 11 through the third discharge pipe 9. The second conveying auger 11 is operated to discharge the ash material through the discharge hopper 12.
[0029] Furthermore, when the equipment is moved away, the ultrasonic sensor 13 can no longer detect the equipment under the discharge hopper 12, and controls the second ash discharge valve 10 and the second motor 1101 to stop running, so that the ash material is temporarily stored in the buffer bin 8. The ash material quality in the buffer bin 8 is monitored in real time by the pressure sensor 801. When the ash material stored in the buffer bin 8 exceeds the set value, the pressure sensor 801 sends a stop operation command to the first motor 701 and the first ash discharge valve 6, so that the ash material temporarily accumulates in the upstream equipment body 1.
[0030] Through the above steps, the upstream equipment body 1 is fixedly supported by the fixed frame 2. The operation of the upstream equipment body 1 is controlled by the main control board 3. After the upstream equipment body 1 starts, the first ash discharge valve 6 is delayed to start by the time relay 4. The delayed control of the first ash discharge valve 6 to open the first discharge pipe 5, and the ash material in the upstream equipment body 1 is transported to the first conveying auger 7 through the first discharge pipe 5. The ash material is transported to the buffer bin 8 in an orderly manner by the first conveying auger 7. The opening and closing of the third discharge pipe 9 is flexibly controlled by the second ash discharge valve 10. The ash material in the buffer bin 8 is transported to the second conveying auger 11 through the third discharge pipe 9. The ash material is transported to the discharge hopper 12 through the second conveying auger 11. The ash material is discharged through the discharge hopper 12. The ultrasonic sensor 13 senses the equipment below the discharge hopper 12, so that the material enters the downstream equipment in a smoother manner, allowing the motor, transmission device, etc. to gradually reach a stable operating state, avoiding blockage caused by uneven instantaneous load, poor material connection or mechanical conflict.
[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
