Description

Technical Field

[0001] The present invention relates to the technical field of pipeline dust removal, and more specifically, the present invention relates to an automatic dust cleaning valve at the end of a horizontal pipeline. Background Art

[0002] In production workshops for dust such as wood chips and flour, a dust removal system generally needs to be installed. Such systems usually suck various dusts in the workshop to the outside of the workshop through pipelines for dust removal. During the installation of the pipelines, it is necessary to turn or change the pipeline diameter to meet the needs of pipeline layout inside and outside the workshop. In view of this, when dust passes through the pipeline, a lot of dust is likely to accumulate in large quantities at the bends or the positions where the pipeline diameter changes. This requires regular dust removal inside the pipeline, otherwise it is easy to cause accumulation inside the pipeline, affecting the dust removal effect inside the workshop. In the prior art, for dust removal of pipelines, a three-way valve is generally installed at the end of the pipeline, and a dust cleaning valve is provided on the three-way valve to regularly clean the dust inside the pipeline. However, during the cleaning process, due to a large amount of dust often accumulating inside the pipeline, a large amount of dust will also accumulate inside the dust cleaning valve, affecting the dust removal efficiency of the dust cleaning valve for the inside of the pipeline. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides an automatic dust cleaning valve at the end of a horizontal pipeline.

[0004] To achieve the above object, the innovation points of the present invention are as follows: Its structure includes a rectangular frame and a valve plate. The inside of the rectangular frame is a hollow cavity. Symmetric ash inlet pipes and ash suction pipes are respectively provided at both ends of the rectangular frame. The ash inlet pipes and the ash suction pipes are both connected to the cavity and are arranged opposite to each other. The valve plate is movably arranged up and down inside the cavity, and a driving member for driving the valve plate to move up and down is provided inside the ash inlet pipe; A circular transition area is formed between the ash inlet pipe and the ash suction pipe. The valve plate is used to close or open the transition area. When the valve plate closes the transition area, there is a blowing area between the bottom of the valve plate and the bottom of the cavity. When the valve plate opens the transition area, the valve plate is tangent to the top of the transition area; A plurality of blowing nozzles are provided at the bottom of the blowing area, and the blowing direction of the blowing nozzles faces the transition area.

[0005] Further, a diversion area is provided at the bottom of the valve plate. The two sides of the diversion area are inclined inner inclined surfaces, and the width of the diversion area increases sequentially from bottom to top. An inclined outer inclined surface is provided between the blowing area and the transition area. When the valve plate closes the transition area, a dust guiding area is formed between the inner inclined surface and the outer inclined surface, and the blowing direction of the blowing nozzles blows along the guiding area towards the transition area.

[0006] Further, the inner inclined surface is parallel to the outer inclined surface.

[0007] Further, the bottom of the above diversion area is an arc surface.

[0008] Further, one side of the above rectangular frame is provided with a connecting plate perpendicular to the movement direction of the valve plate. The top of the valve plate is provided with a driving plate parallel to the connecting plate. The driving member acts on the driving plate to make the valve plate move inside the cavity.

[0009] Further, the above driving member includes a micro cylinder and a solenoid valve. The micro cylinder is fixed inside the ash inlet pipe. The output end of the micro cylinder sequentially penetrates through the ash inlet pipe, the connecting plate and is connected to the driving plate. The solenoid valve is connected to the air inlet of the micro cylinder and is located between the ash inlet pipe and the connecting plate.

[0010] Further, both sides inside the above cavity are provided with chutes, and both ends of the valve plate are provided with symmetrical sliding plates that are slidably arranged inside the chutes.

[0011] Technical effects and advantages of the present invention: By arranging a blowing nozzle at the bottom of the blowing area, keeping the blowing nozzle always open, and cooperating with the position where the valve plate moves up and down and stays, it ensures that the inside of the rectangular frame is always unobstructed, thereby ensuring the ash cleaning efficiency of the ash cleaning valve at the end of the horizontal pipe.

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0015] As From Figure 1 to Figure 2 A specific embodiment of the present invention, its structure includes a rectangular frame 1 and a valve plate 11. The inside of the rectangular frame 1 is a hollow cavity 12. Symmetrical ash inlet pipes 13 and ash suction pipes 14 are respectively provided at both ends of the rectangular frame 1. The ash inlet pipes 13 and the ash suction pipes 14 are both connected to the cavity 12 and are arranged opposite to each other. The valve plate 11 is movably arranged up and down inside the cavity 12. A driving member 2 for driving the valve plate 11 to move up and down is provided inside the ash inlet pipe 13; A circular transition area 15 is formed between the ash inlet pipe 13 and the ash suction pipe 14. The valve plate 11 is used to close or open the transition area 15. When the valve plate 11 closes the transition area 15, there is a blowing area 16 between the bottom of the valve plate 11 and the bottom of the cavity 12. When the valve plate 11 opens the transition area 15, the valve plate 11 is tangent to the top of the transition area 15. A number of blowing nozzles 17 are provided at the bottom of the blowing area 16, and the blowing direction of the blowing nozzles 17 faces the transition area 15.

[0016] In the present invention, the process of automatic ash cleaning at the end of the horizontal pipe is as follows: The driving member 2 drives the valve plate 11 to move, so that the valve plate 11 opens the transition area 15. At this time, the valve plate 11 is tangent to the top of the transition area 15. This tangency of the valve plate 11 can block the space at the top of the transition area 15. Subsequently, an external air extraction pump acts on the ash suction pipe 14, so that the dust inside the horizontal pipe is sucked into the ash suction pipe 14 through the ash inlet pipe 13 and the transition area 15. During this process, the blowing nozzles are always in the open state, so as to avoid dust falling below the transition area 15, and further avoid dust accumulation inside the rectangular frame 1. When the dust inside the horizontal pipe is cleaned up, the external air extraction pump is turned off, and the driving member 2 drives the valve plate 11 to move, so that the valve plate 11 closes the transition area 15. At this time, the blowing nozzles are still kept open, so as to avoid the dust flowing through the horizontal pipe from standing still inside the rectangular frame 1, keep the inside of the rectangular frame 1 unobstructed, and avoid dust accumulation inside the rectangular frame 1, which affects the opening or closing of the subsequent valve plate 11.

[0017] In the present invention, by providing the blowing nozzles 17 at the bottom of the blowing area 16 and keeping the blowing nozzles 17 always in the open state, and at the same time cooperating with the position where the valve plate 11 moves up and down and stays, it is ensured that the inside of the rectangular frame 1 is always unobstructed, and thus the ash cleaning efficiency of the ash cleaning valve at the end of the horizontal pipe is ensured.

[0018] In the present invention, as a preferred solution, a diversion area 3 is provided at the bottom of the valve plate 11. The two sides of the diversion area 3 are inclined inner inclined surfaces 31, and the width of the diversion area 3 increases sequentially from bottom to top. An inclined outer inclined surface 32 is provided between the blowing area 16 and the transition area 15. When the valve plate 11 closes the transition area 15, a dust guiding area 33 is formed between the inner inclined surface 31 and the outer inclined surface 32, and the blowing direction of the blowing nozzles 17 blows air along the guiding area 33 towards the transition area 15.

[0019] In the present invention, during the blowing process of the blowing nozzles 17, the blowing blows air towards the transition area 15 through the guiding area 33, so that the dust flows along the guiding area 33 towards the transition area 15. The setting of the inner inclined surface 31 and the outer inclined surface 32 can avoid dust residue, so that the dust inside the rectangular frame 1 can be removed maximally.

[0020] In the present invention, as a preferred solution, the inner inclined surface 31 is parallel to the outer inclined surface 32.

[0021] In the present invention, the inner inclined surface 31 and the outer inclined surface 32 are parallel to each other, so that the shape of the diversion area 3 is a parallelogram, and thus the air blown by the air blowing nozzle 17 flows smoothly in the diversion area 3.

[0022] In the present invention, as a preferred solution, the bottom of the diversion area 3 is an arc surface 4.

[0023] In the present invention, the setting of the arc surface 4 can prevent dust from being adsorbed on the bottom of the valve plate 11.

[0024] In the present invention, as a preferred solution, a connecting plate 5 is provided on one side of the rectangular frame 1. The connecting plate 5 is perpendicular to the moving direction of the valve plate 11. A driving plate 51 is provided on the top of the valve plate 11. The driving plate 51 is parallel to the connecting plate 5. The driving member 2 acts on the driving plate 51 to make the valve plate 11 move inside the cavity 12.

[0025] In the present invention, the driving member 2 drives the driving plate 51 to move, thereby realizing the movement of the valve plate 11 inside the cavity 12.

[0026] In the present invention, as a preferred solution, the driving member 2 includes a micro cylinder 21 and a solenoid valve 22. The micro cylinder 21 is fixed inside the ash inlet pipe 13. The output end of the micro cylinder 21 sequentially penetrates through the ash inlet pipe 13, the connecting plate 5 and is connected to the driving plate 51. The solenoid valve 22 is connected to the air inlet of the micro cylinder 21 and is located between the ash inlet pipe 13 and the connecting plate 5.

[0027] In the present invention, the working principle of the driving member 2 is as follows: when it is necessary to open the valve plate 11, the solenoid valve 22 is opened, so that the micro cylinder 21 is opened, and then the driving plate 51 is pushed to move.

[0028] In the present invention, as a preferred solution, sliding grooves 6 are provided on both sides inside the cavity 12. Symmetrical sliding plates 61 are provided at both ends of the valve plate 11. The sliding plates 61 are slidably arranged inside the sliding grooves 6.

[0029] In the present invention, the arrangement of the sliding plates 61 sliding inside the sliding grooves 6 ensures the stability of the movement of the valve plate 11 inside the cavity 12.
