Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal and environmental protection equipment, and particularly relates to a pipeline dust cleaning device. Background Art

[0002] At present, in the design and maintenance of existing dust suction pipeline systems, the sedimentation problem is a challenge that cannot be ignored. The dust sedimentation in the pipeline not only reduces the dust suction efficiency, but may also accumulate into flammable substances, increasing the fire risk. In addition, the accumulation of sediment will increase the weight of the pipeline. Once it exceeds the bearing limit, it may cause the pipeline to fall, causing harm to the personnel and equipment below, resulting in serious economic losses and safety accidents. To address this problem, it is common practice to set observation windows and dust cleaning ports on the pipeline. According to the standard, there should be such a setting every 6 meters. However, the traditional dust cleaning port design has certain limitations. They usually just open a hole in the pipeline and install a door that can be opened. When cleaning, it is necessary to manually open the door and use long tools for cleaning. This method is not only cumbersome to operate, but also has certain safety risks. The prior art also conducts pipeline dust cleaning by means of regular cleaning, but this method cannot detect the cleaning effect and cannot reasonably plan the cleaning time. A short cleaning time may lead to incomplete cleaning, and a long cleaning time may lead to waste of resources.

[0003] The utility model designs a pipeline dust cleaning device to solve the above technical problems. Content of the Utility Model

[0015] Compared with the related art, the beneficial effects of the present utility model are as follows:

[0016] The utility model hoists a pipeline through a hoisting assembly, and uses a tensile force detector to detect the magnitude of the hoisting tensile force.

[0025] Combined with Figure 1 As shown, the present disclosure embodiment provides a pipeline dust cleaning device, including a hoisting assembly 1, a dust cleaning valve 2, a pressure sensor, and a central dust collector 3. The hoisting assembly 1 includes a hoisting member 11 and a tension detector 12. The number of the hoisting members 11 is multiple, and the multiple hoisting members 11 are arranged at intervals on the pipeline, with one end lifting the pipeline and the other end fixedly connected to the workshop ceiling. The tension detector 12 is arranged on the hoisting member 11 for detecting the tension of the hoisted pipeline. The number of the dust cleaning valves 2 is multiple, and the multiple dust cleaning valves 2 are arranged on the pipeline and are arranged opposite to the hoisting member 11. The central dust collector 3 is connected to the end of the pipeline. The pressure sensor is arranged inside one end of the pipeline close to the central dust collector 3 for detecting the pressure inside the pipeline.

[0026] By using the pipeline dust cleaning device provided by the present disclosure embodiment, the pipeline is hoisted by setting the hoisting assembly 1, and the tension detector 12 is used to detect the magnitude of the hoisting tension. When the tension detection value is greater than the preset tension value, it indicates that excessive dust has accumulated at this part of the pipeline and needs to be cleaned. Open the corresponding dust cleaning valve 2 at this place. The pressure sensor detects that the pressure inside the pipeline decreases, increases the working power of the central dust collector 3, increases the working air volume, increases the wind speed inside the pipeline, and sucks the excessive dust inside the pipeline into the central dust collector 3 for filtering and collection to realize pipeline dust cleaning. When the tension detector 12 detects that the tension value is less than or equal to the preset value, close the dust cleaning valve 2 to complete the entire pipeline dust cleaning process.

[0027] Compared with the prior art, the dust cleaning process provided by the present disclosure embodiment is simpler, can avoid potential safety hazards, and can detect the cleaning effect and reasonably plan the cleaning time through the detection data of the tension detector 12, avoiding incomplete cleaning and unnecessary energy waste, and achieving a better dust cleaning effect.

[0028] Based on the above technical solution, the multiple hoisting members 11 are evenly spaced on the pipeline.

[0029] Based on the above technical solution, the pipeline dust cleaning device further includes an alarm 4. The number of the alarms 4 is multiple, and the multiple alarms 4 are respectively connected to the multiple tension detectors 12, and are used to alarm and remind that the tension value detected by the tension detector 12 is greater than a preset tension value.

[0030] Based on the above technical solution, the pipeline dust cleaning device further includes a first controller 5. The first controller 5 is connected to the alarm 4 and the dust cleaning valve 2, and is used to control the opening and closing of the dust cleaning valve 2 according to the alarm reminder of the alarm 4.

[0031] Based on the above technical solution, the pipeline dust cleaning device further includes a display device 6. The display device 6 is connected to the alarm 4 and is used to display the alarm reminder of the alarm 4.

[0032] Based on the above technical solution, the pipeline dust cleaning device further includes a second controller. The second controller is connected to the pressure sensor and the central dust collector 3, and is used to control the opening and closing of the central dust collector 3 according to the signal of the pressure sensor.

[0033] Working principle of the pipeline dust cleaning device: Multiple tension detectors 12 detect the tension of pipeline hoisting. When the tension detection value is greater than the preset tension value, the alarm 4 corresponding to the tension detector 12 will send an alarm reminder. This alarm reminder signal will be transmitted to the first controller 5, and the first controller 5 will control the dust cleaning valve 2 corresponding to this alarm 4 to open. When the dust cleaning valve 2 is opened, the pressure in the pipeline will decrease. When the pressure sensor detects that the pressure value in the pipeline decreases, it will transmit the signal to the second controller, and the second controller will control the central dust collector 3 to increase the working power to increase the wind speed in the pipeline. The high wind speed can suck the dust in the pipeline into the central dust collector 3. At this time, the tension detection value of the tension detector 12 gradually decreases until it is detected to be less than or equal to the preset tension value, and the first controller 5 closes the corresponding dust cleaning valve 2. When the pressure sensor detects that the pressure in the pipeline returns to the normal range, the second controller restores the working power of the central dust collector 3 to the normal working state, and completes the pipeline dust cleaning process.

[0034] The pipeline dust cleaning device provided by the embodiment of the present disclosure realizes the automatic monitoring and feedback of pipeline settlement, forms a closed loop with the cleaning system, and can more intelligently achieve the pipeline dust cleaning effect.

The fan system 31 is connected to the second controller. The filtration system 33 is connected to a pipeline. The pulse system 32 is arranged on the top of the filtration system 33, and the ash collection system 34 is arranged at the bottom of the filtration system 33.

[0036] Specifically, the setting of the fan system 31 can ensure the air volume and air speed in the pipeline. The filtration system 33 includes a filtration device. The fan system 31 conveys the dust in the pipeline to the filtration device for filtration. The filtered dust and waste residues are collected in the ash collection system 34 for unified treatment. The setting of the pulse system 32 can clean the filtration device that has been working for a long time, and use the pulse of the gas to impact and vibrate the waste residues and dust in the filtration device into the ash collection system 34.

[0037] Based on the above technical solution, the pipeline dust cleaning device further includes an observation window 7. The number of observation windows 7 is multiple, and the multiple observation windows 7 are arranged at intervals at the bottom of the pipeline.
