Abstract
Description
Technical Field
[0001] This utility model relates to the field of pneumatic ash conveying technology, and in particular to a pneumatic ash conveying debris cleaning device. Background Technology
[0002] As an important dry ash conveying equipment in industries such as power, metallurgy, and chemical industry, pneumatic ash conveying systems in metallurgical production dust collectors suck in some debris, such as plastic sheeting and cotton yarn, from various dust collection points into the ash hopper. This debris then enters the silo pump below the ash hopper and from there enters the ash conveying pipeline, causing blockage. Therefore, a dust collection structure needs to be installed below the silo pump.
[0003] Currently, existing pneumatic ash conveying systems lack dedicated, high-efficiency debris cleaning devices. Commonly, a single filter screen is installed inside the pipeline to block impurities. However, over time, manual cleaning of the filter screen requires opening a sealed cover on one side of the pipeline, which is time-consuming and labor-intensive. Therefore, to better facilitate the cleaning of impurities from the filter screen inside pneumatic ash conveying pipelines, promote technological progress in the industry, and enhance core technological competitiveness, this application proposes a new implementation scheme for debris cleaning devices in pneumatic ash conveying systems, which differs from existing technologies. Utility Model Content
[0004] The purpose of this invention is to solve the problem of the lack of dedicated and efficient debris cleaning devices, and to propose a pneumatic conveying debris cleaning device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A pneumatic ash and debris cleaning device includes a first conveying pipe and a second conveying pipe. The bottom end of the first conveying pipe is fixedly connected to a first connecting pipe, and the top end of the second conveying pipe is fixedly connected to a second connecting pipe. A rotating pipe is rotatably connected between the second connecting pipe and the first connecting pipe. A filter screen is clamped inside the rotating pipe. A through hole is provided on one side of the rotating pipe, and a dust collection box is slidably connected inside the through hole. The dust collection box is located above the filter screen. A dust collection port is provided at the bottom of the dust collection box, and a dust collection pipe is sealed and inserted into one end of the dust collection box.
[0007] Furthermore, a silo pump is connected to the top of the first conveying pipe via a flange.
[0008] Furthermore, an observation window is embedded on one side of the first connecting tube.
[0009] Furthermore, a handle is fixedly connected to the outer circumference of the rotating tube, and an anti-slip sleeve is fitted onto the outer wall of the handle.
[0010] Furthermore, a sealing rubber ring is snapped into the through hole, and the sealing rubber ring is in contact with the dust collection box.
[0011] Furthermore, an inner stop plate is fixedly connected to one end of the top outer wall of the dust collection box, and an outer stop plate is fixedly connected to the other end of the top outer wall of the dust collection box.
[0012] Furthermore, the inner stop plate is located inside the first connecting pipe, and the outer stop plate is located outside the first connecting pipe.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. By connecting an external vacuum cleaner to the suction pipe, debris is sucked into the dust collection box from the suction port and then discharged through the suction pipe. At the same time, turning the handle rotates the rotating tube, which in turn rotates the filter screen to clean all the debris off the filter screen, improving the cleaning effect.
[0015] 2. The sealing rubber ring inside the through hole can seal the dust collection box and the through hole, thus preventing dust leakage. Attached Figure Description

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figures 1-5A pneumatic conveying and cleaning device for ash and debris includes a first conveying pipe 2 and a second conveying pipe 3. A first connecting pipe 4 is welded to the bottom end of the first conveying pipe 2, and a second connecting pipe 5 is welded to the top end of the second conveying pipe 3. A rotating pipe 6 is rotatably connected between the second connecting pipe 5 and the first connecting pipe 4. The rotating pipe 6 has slots at both ends, and a sealing ring is provided in the slot. One end of the second connecting pipe 5 and the first connecting pipe 4 rotates in the slot of the rotating pipe 6.
[0024] A filter screen 9 is inserted inside the rotating tube 6. The filter screen 9 has a pore size of 4-5mm. A handle 8 is welded to the outer circumference of the rotating tube 6. Turning the handle 8 will cause the rotating tube 6 to rotate, thereby causing the filter screen 9 to rotate.
[0025] A through hole 10 is provided on one side of the rotating tube 6. A dust collection box 12 is slidably connected inside the through hole 10. The dust collection box 12 is located above the filter screen 9. A dust collection port 16 is provided at the bottom of the dust collection box 12. A dust collection tube 15 is sealed and inserted into one end of the dust collection box 12. The dust collection tube 15 can be connected to an external dust collection device.
[0026] The dust collection box 12 is pushed into the first connecting pipe 4, and then the debris is sucked into the dust collection box 12 from the dust collection port 16 under the action of the external vacuuming equipment. Then, it is discharged through the vacuum pipe 15 to clean up the debris.
[0027] The top end of the first conveying pipe 2 is connected to the silo pump 1 via a flange.
[0028] An observation window 7 is embedded on one side of the first connecting pipe 4 to observe the usage of the filter screen 9.
[0029] The outer wall of the handle 8 is fitted with an anti-slip sleeve, which facilitates the operation of the handle 8.
[0030] A sealing rubber ring 11 is fitted inside the through hole 10. The sealing rubber ring 11 contacts the dust collection box 12, thereby sealing the dust collection box 12 and the through hole 10 to prevent dust leakage.
[0031] One end of the top outer wall of the dust collection box 12 is fixed with an inner stop plate 13 by bolts, and the other end of the top outer wall of the dust collection box 12 is fixed with an outer stop plate 14 by bolts, thereby preventing the dust collection box 12 from falling off the through hole 10. The maximum extension distance of the dust collection box 12 inside the first connecting pipe 4 is greater than the radius of the first connecting pipe 4.
[0032] The inner stop plate 13 is located inside the first connecting pipe 4, and the outer stop plate 14 is located outside the first connecting pipe 4.
[0033] The working principle of this embodiment is as follows: When in use, dust falls into the silo pump 1, then enters the first conveying pipe 2, and then is transported away through the first connecting pipe 4, rotating pipe 6, second connecting pipe 5, and second conveying pipe 3. During this process, the impurities carried in the dust are filtered and trapped on the filter screen 9.
[0034] During cleaning, the suction pipe 15 is connected to the external high-pressure vacuum cleaner. Then, the dust collection box 12 is pushed into the first connecting pipe 4 until the outer stop plate 14 contacts the outer wall of the first connecting pipe 4. Under the action of the vacuum cleaner, the debris is sucked into the dust collection box 12 from the suction port 16 and then discharged through the suction pipe 15. At the same time, the handle 8 is turned to drive the rotating pipe 6 to rotate, thereby driving the filter screen 9 to rotate so as to clean all the debris on the filter screen 9.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
