Description

Technical Field

[0001] The utility model relates to the field of pulse dust collectors, in particular to an air guide frame buffer structure of a pulse dust collector. Background Art

[0002] Sandblasting machine is a common surface treatment machine. It uses high-speed spraying of various specifications of sand to polish the workpiece, remove impurities and other surface treatments. Therefore, the existing sandblasting machine will generate a lot of sand and dust. In order to remove the dust from the sandblasting machine, a dust removal device is usually set on one side of the sandblasting machine. The dust removal device consists of a dust removal pipeline, a dust collection hopper, a dust removal box, a pulse dust collector, an air guide frame, an exhaust pipe and a filter element. After the dust removal device removes the sand and dust, the dust is discharged into the dust removal box through the dust removal pipeline. After the dust in the gas is filtered by the filter element, the sand and dust will adhere to the outer edge of the filter element. Finally, the filtered gas is discharged from the exhaust pipe. The filter element and the pulse dust collector are arranged in the dust removal box, and the air guide frame is arranged in the air blowing pipe of the pulse dust collector. When the outer edge of the filter element is attached with a lot of sand and dust, the air blowing pipe of the pulse dust collector blows air to the inside of the filter element, and the air guide frame guides the wind to the inside of the filter element, so that the gas blows in the opposite direction to the outer edge of the filter element, so that the dust on the outer edge of the filter element is blown into the ash collecting hopper for collection. However, when the gas ejected from the pulse dust collector is discharged by the air guide frame, the gas will also generate an impact force on the air guide frame. However, the current air guide frames are fixed under the air blowing pipe of the pulse dust collector by supporting columns, which makes the supporting columns of the air guide frame easily broken under the action of the impact force, causing the air guide frame to fall. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the utility model provides a buffer structure of an air guide frame of a pulse dust collector, aiming to solve the technical problem that the current air guide frames are fixed under the air blowing pipe of the pulse dust collector through support columns, which causes the support columns of the air guide frames to be easily broken under the action of impact force, causing the air guide frame to fall.

[0004] The technical solution of the utility model to solve the above technical problems is:

[0005] A pulse dust collector air guide frame buffer structure comprises a dust collection box body, a pulse dust collector and a filter element are arranged inside the dust collection box body, an air outlet end of the pulse dust collector is provided with an air blowing pipe, an outer edge of the air blowing pipe is provided with a mounting seat, a guide frame is provided at the bottom of the mounting seat, the air blowing pipe and the guide frame are located inside the filter element, and also comprises a buffer spring, one end of the buffer spring is provided with a first fixed end, the first fixed end is connected to the top of the guide frame, the other end of the buffer spring is provided with a second fixed end, the second fixed end is connected to the bottom of the mounting seat, a guide support rod is provided at the top of the guide frame, a guide groove is opened inside the mounting seat, the guide groove runs through both sides of the mounting seat, one end of the guide support rod is provided with a sliding end, the sliding end passes through the interior of the buffer spring so that the sliding end slides with the guide groove.

[0006] When the air pipe of the pulse dust collector sprays air to the guide frame, the guide frame drives the sliding end of the guide support rod to slide along the guide groove of the mounting seat, thereby guiding the sliding position of the guide frame so that the guide frame can only move up and down. When the guide frame drives the sliding end of the guide support rod to slide, the guide frame also drives the buffer spring to deform at the same time, thereby buffering the impact force of the gas and protecting the guide support rod to prevent the guide support rod from breaking under the impact force of the gas.

[0007] Further, in the present application, a shock-absorbing sleeve is provided inside the guide groove, the shock-absorbing sleeve is elastic, and the sliding end is slidably matched with the inside of the shock-absorbing sleeve.

[0008] When the sliding end of the guide support rod moves, the sliding end of the guide support rod slides along the shock-absorbing sleeve of the guide groove. The elasticity of the shock-absorbing sleeve avoids the sliding end of the guide support rod from colliding with the guide groove, thereby reducing the noise caused by the collision between the sliding end of the guide support rod and the guide groove.

[0009] Further, in the present application, a limit block is provided at one end of the sliding end, the size of the limit block is larger than the guide groove, and the limit block is located on one side of the guide groove.

[0010] When the sliding end of the guide rod slides to one side of the guide groove, the limit block will interfere with the mounting seat because the size of the limit block is larger than the guide groove, thereby facilitating the position of the guide rod to be limited and preventing the sliding end of the guide rod from leaving the guide groove.

[0011] Furthermore, in the present application, a first fixing seat is provided on the top of the guide frame, a first fixing cavity is opened inside the first fixing seat, the first fixing cavity matches the shape of the first fixing end, and the first fixing end is installed inside the first fixing cavity.

[0012] Further, in the present application, first fixing protrusions are provided on both sides of the first fixing cavity, and the first fixing protrusions on both sides of the first fixing cavity are clamped with both sides of the first fixing end.

[0013] Further, in the present application, a guide block is provided on one side of the first fixing seat, guide slopes are provided on both sides of the guide block, and the guide block is located below the blowing pipe.

[0014] Furthermore, in the present application, a second fixing seat is provided at the bottom of the mounting seat, a second fixing cavity is opened inside the second fixing seat, the second fixing cavity matches the shape of the second fixing end, and the second fixing end is installed inside the second fixing cavity.

[0015] Further, in the present application, second fixing protrusions are provided on both sides of the second fixing cavity, and the second fixing protrusions on both sides of the second fixing cavity are clamped with both sides of the second fixing end.

[0016] Furthermore, in the present application, the guide frame is in the shape of a cone, and the pointed surface of the guide frame faces downward of the air blowing tube.

[0017] Furthermore, in the present application, a dust collecting funnel is provided at the bottom of the dust removal box, and the dust collecting funnel is connected to the interior of the dust removal box.

[0018] The utility model has the following beneficial effects:

[0019] When the air pipe of the pulse dust collector sprays air to the guide frame, the guide frame drives the sliding end of the guide support rod to slide along the guide groove of the mounting seat, thereby guiding the sliding position of the guide frame so that the guide frame can only move up and down. When the guide frame drives the sliding end of the guide support rod to slide, the guide frame also drives the buffer spring to deform at the same time, thereby buffering the impact force of the gas and protecting the guide support rod to prevent the guide support rod from breaking under the impact force of the gas.

[0032] Reference Figure 1-Figure 5 In some specific embodiments, a pulse dust collector air guide frame buffer structure includes a dust removal box 1, a pulse dust collector 3 and a filter element 2 are arranged inside the dust removal box 1, an air outlet end of the pulse dust collector 3 is provided with an air blowing pipe 4, an outer edge of the air blowing pipe 4 is provided with a mounting seat 21, a guide frame 5 is provided at the bottom of the mounting seat 21, the air blowing pipe 4 and the guide frame 5 are located inside the filter element 2, and also includes a buffer spring 6, one end of the buffer spring 6 is provided with a first fixed end 10, the first fixed end 10 is connected to the top of the guide frame 5, the other end of the buffer spring 6 is provided with a second fixed end 11, the second fixed end 11 is connected to the bottom of the mounting seat 21, a guide support rod 8 is provided at the top of the guide frame 5, a guide groove 7 is opened inside the mounting seat 21, the guide groove 7 runs through both sides of the mounting seat 21, and one end of the guide support rod 8 is provided with a sliding end 9, the sliding end 9 passes through the interior of the buffer spring 6, so that the sliding end 9 and the guide groove 7 are slidably matched.

[0033] Through the above technical solution, when the air blowing pipe 4 of the pulse dust collector 3 sprays air to the guide frame 5, the guide frame 5 drives the sliding end 9 of the guide support rod 8 to slide along the guide groove 7 of the mounting seat 21, thereby guiding the sliding position of the guide frame 5, so that the guide frame 5 can only move up and down. When the guide frame 5 drives the sliding end 9 of the guide support rod 8 to slide, the guide frame 5 also drives the buffer spring 6 to deform at the same time, thereby buffering the impact force of the gas and protecting the guide support rod 8 to prevent the guide support rod 8 from breaking under the impact force of the gas.

[0034] It should be noted that the guide frame 5 will move without direction after being impacted by the gas. If the guide frame 5 moves left or right, it will cause the guide frame 5 to be too inclined to one side of the filter element 2, resulting in more gas being ejected from one side of the filter element 2 and incomplete gas coverage. In this regard, a guide support rod 8 is provided on the top of the guide frame 5, so that when the guide frame 5 is subjected to the impact force of the gas, the sliding end 9 of the guide frame 5 can only slide up and down, thereby preventing the guide frame 5 from being too inclined to one side of the filter element 2, and the up and down sliding can effectively spray the middle and lower layers of the filter element 2, thereby increasing the gas coverage area.
