Description

Technical Field

[0001] The present disclosure relates to the technical field of silo cleaning, and in particular to a mobile silo cleaning device. Background Art

[0002] During production, the furnace gas discharged from the calcium carbide furnace will first enter the water-cooled flue, which will cool it down for the first time; the furnace gas flowing out of the water-cooled flue will further enter the first-stage cyclone dust collector and the third-stage air cooler for further cooling. At the same time, the cyclone dust collector and the air cooler can also filter out large particles of dust; then the furnace gas is pressurized by the rough air fan and enters the three filters. The filters filter the remaining dust in the furnace gas to remove all the dust in the furnace gas.

[0003] The dust filtered out from the air cooler and filter will gather in the conical silo below the air cooler and filter. The dust is very easy to accumulate in the conical silo and cause blockage. If it is not cleaned in time, it is likely to cause blockage of the furnace body.

[0004] To prevent blockage, an electric vibrator is usually welded on the conical silo, and the vibration of the electric vibrator allows the dust to be discharged smoothly, thereby improving the dust cleaning effect. However, the electric vibrator is welded and fixed to a fixed position in the conical silo, and can only vibrate locally, but cannot knock the conical silo completely, resulting in poor cleaning effect; and it also needs to be assisted by manual knocking, resulting in a waste of manpower.

[0032] This solution provides a mobile warehouse cleaning device, which includes a mobile mechanism 2, a slewing mechanism 5, a pitching drive mechanism 4 and a telescopic arm 6. The mobile mechanism 2 is configured to be able to move along a track or directly; the slewing mechanism 5 is installed on the mobile mechanism 2 to drive the pitching drive mechanism 4 and the telescopic arm 6 to rotate; the pitching drive mechanism 4 is arranged between the telescopic arm 6 and the slewing mechanism 5 to drive the telescopic arm 6 to perform a pitching action, and one end of the telescopic arm 6 is provided with a striking hammer 7 that can clean the silo by fitting to the silo and generating vibration.

[0033] The mobile mechanism 2 can move on the ground or other supporting base to move around the silo to be cleaned, wherein the mobile mechanism 2 can be driven by electricity, fuel, etc. The mobile mechanism 2 can move over a large range to adjust the position of the overall structure to facilitate the cleaning operation of the silo.

[0034] The slewing mechanism 5 is arranged on the moving mechanism 2 , and can drive the telescopic arm 6 thereon to slew. The pitch driving mechanism 4 can drive the telescopic arm 6 to pitch relative to the slewing mechanism 5 . The striking hammer 7 is arranged at one end of the telescopic arm 6 .

[0035] It can be seen that the telescopic arm 6 can perform rotational and pitching movements through the slewing mechanism 5 and the pitching drive mechanism 4, so as to adjust the angle and position of the percussion hammer 7 so as to fit with the silo and clean the silo through the vibration of the percussion hammer 7.

[0039] In some embodiments, the telescopic drive mechanism 63 may include a motor, a chain and a sprocket. When the motor is running, the sprocket can be driven to rotate by the chain. The movable arm 61 is provided with a rack that meshes with the sprocket and extends in the same direction as the movable arm 61.

Of course, in other embodiments, the telescopic drive mechanism 63 may also include an oil cylinder, an air cylinder, etc., whose two ends are respectively connected to the movable arm 61 and the support member 62. Among them, the support member 62 can be roughly formed into a sleeve shape, and the movable arm 61 is arranged through the support member 62.

The slewing mechanism 5 may include a slewing base 53 and a slewing support 52 rotatably arranged on the slewing base 53, the slewing base 53 is arranged on the moving mechanism 2, and the slewing support 52 is provided with a telescopic arm 6, for example, the support member 62 is rotatably hinged to the slewing support 52. A rotary drive member 51 (such as a rotary motor or other similar drive member) is arranged on the rotary base 53 or the rotary support 52 to drive the rotary support 52 to rotate relative to the rotary base 53. The rotation axis of the rotary support 52 can be roughly perpendicular to the support bottom surface of the mobile mechanism 2 (the support bottom surface refers to a plane jointly defined by multiple support points at the bottom of the mobile mechanism 2 (such as the support points of the walking wheels). When the mobile mechanism 2 is set on the ground or other support surfaces, the plane is coplanar with the ground or other support surfaces).

The pitch drive mechanism 4 can be an oil cylinder, an air cylinder, an electric cylinder, etc., one end of which is hinged to the telescopic arm 6 (for example, the support member 62), and the other end is hinged to the slewing support 52. The pitch drive mechanism 4 and the percussion hammer 7 are respectively located on both sides of the slewing mechanism 5, so that the pitch drive mechanism 4 is away from the side of the telescopic arm 6 where the percussion hammer 7 is provided, refer to Figure 1 and Figure 2 As shown, the pitch drive mechanism 4 is located at the top of the mobile mechanism 2 instead of extending from the top of the mobile mechanism 2. Therefore, when the silo is knocking, the pitch drive mechanism 4 is farther away from the silo. On the one hand, it can prevent the pitch drive mechanism 4 from affecting the knocking operation. On the other hand, it can also prevent the pitch drive mechanism 4 from colliding with other structures, thereby extending its service life.

[0042] In other embodiments, the pitch drive mechanism 4 may also be a motor, an engine or a hydraulic motor.

[0043] Among them, in some embodiments, the mobile warehouse cleaning device also includes a knocking drive mechanism 8, and the knocking drive mechanism 8 further includes a fixed seat 81, an extension arm 85 and a hammer driving device 83; the fixed seat 81 is fixedly installed at the end of the telescopic arm 6, the head end of the extension arm 85 is hinged to the fixed seat 81, the end of the extension arm 85 is equipped with a knocking hammer 7, and the hammer driving device 83 is connected to the extension arm 85 and can drive the extension arm 85 to swing relative to the fixed seat 81. The fixed seat 81 can be set at the end of the telescopic arm 6, and the hammer driving device 83 can drive the extension arm 85 to swing relative to the fixed seat 81, that is, the telescopic arm 6, thereby driving the knocking hammer 7 to swing within a certain range, so as to adjust the position of the knocking hammer 7 relative to the telescopic arm 6, so that the knocking hammer 7 can fit the silo for knocking.

[0044] In addition, in some embodiments, there are two extension arms 85, the head ends of the two extension arms 85 are respectively hinged to the two sides of the fixing base 81, and the hammer driving device 83 is connected to the two extension arms 85 and can drive the ends of the two extension arms 85 to move closer to or away from each other.
