Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fluidized bed internal cleaning, in particular to a device for cleaning the interior of a high-risk space. Background Art
[0002] At present, the initial stage of cleaning the interior of the fluidized bed requires a large amount of liquid nitrogen for displacement and cooling. Then, the manhole of the fluidized bed is opened, one end of the hose is connected to the vacuum pump and the other end is connected to the manhole to perform preliminary suction of the silicon powder. The remaining areas with harder scale must be cleaned by workers wearing air respirators and protective clothing, carrying lighting tools and cleaning tools to enter the equipment to achieve thorough cleaning of the silicon powder in the fluidized bed.
[0003] The above cleaning process requires that silicon powder be cleaned in high-risk spaces while the temperature inside the equipment cannot be too high, otherwise the cleaning will be terminated. After the temperature drops, workers will enter again to clean until the cleaning is thorough and passed inspection. The above cleaning process has the following defects:
[0004] 1. Liquid nitrogen is required to maintain the temperature inside the fluidized bed to provide the cleaning personnel with a suitable temperature. If the temperature is not suitable, it needs to be cooled again.
[0005] 2. There are areas with hard scale inside the fluidized bed, and the silicon powder cannot be initially sucked out through the hose + vacuum pump cleaning mode. It must be cleaned again manually afterwards, which takes a long cleaning process and has low processing efficiency.
[0006] 3. When workers enter the fluidized bed for cleaning operations, the equipment is filled with nitrogen and chlorosilane. Cleaners must wear protective clothing and air respirators. However, even with proper protective preparations, there are still safety hazards. Utility Model Content

Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.
[0035] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0036] Example
[0037] See also Figures 1 to 3 This embodiment provides a high-risk space interior cleaning device, including a robotic arm 1, a suction pipe 2, a negative pressure mechanism 3 and a control mechanism 4.
[0038] The high-risk spaces mentioned below refer to enclosed spaces inside equipment such as fluidized beds.
[0039] The robot arm 1 includes a driving assembly 11 with multiple degrees of freedom. The end 12 of the driving assembly is detachably connected to a gripper 13. The end 12 of the driving assembly and the gripper 13 can be moved to a designated position in a high-risk space.
[0040] One end of the straw 2 is connected to the negative pressure mechanism 3, and the other end is installed at the end 12 of the driving assembly. The driving assembly 11 can drive the gripper 13 and the straw 2 to move to a designated position in the high-risk space.
[0041] The negative pressure mechanism 3 is arranged outside the high-risk space and is used to provide negative pressure for the suction tube 2. The negative pressure mechanism 3 is, for example, a vacuum pump.
[0042] The control mechanism 4 is arranged outside the high-risk space and is used to control the action of the drive assembly 11. The control mechanism 4 includes a console or a control handle associated with the drive assembly 11.
[0043] This embodiment applies a robotic arm 1 that has been used in other fields to the cleaning work inside a fluidized bed. Specifically, a manhole on the fluidized bed is first opened, and the end 12 of the driving component carries the suction pipe 2 into the fluidized bed from the manhole to preliminarily clean the silicon powder inside the fluidized bed. The end 12 of the driving component is then moved outside the fluidized bed, and a gripper 13 is connected to the end 12 of the driving component. A crushing tool such as a broom, a shovel or a hammer is installed on the gripper 13 (not shown in the figure). The driving component 11 drives the gripper 13 and the crushing tool to move to an area where scaling exists through the control mechanism 4, and the scaled silicon powder is crushed by the crushing tool. The gripper 13 and the crushing tool are then moved outside the fluidized bed, and the gripper 13 and the crushing tool are disassembled, so that the end 12 of the driving component carries the suction pipe 2 into the fluidized bed from the manhole to clean the silicon powder inside the fluidized bed.
[0044] It can be seen that in this embodiment, when cleaning the interior of the fluidized bed, since there is no need for manual entry into the fluidized bed, there is no need to repeatedly cool the interior of the fluidized bed, and there is no need to equip workers with a large amount of protective equipment, which is more efficient and safer.
[0045] The mechanical arm 1 and / or the suction pipe 2 are made of high temperature resistant and corrosion resistant materials, which can effectively prevent the influence of the internal environment of the fluidized bed to ensure the service life. The suction pipe 2 is, for example, a metal hose.
[0046] In this embodiment, the robotic arm 1 is preferably a multi-jointed robotic arm 1, with the suction pipe 2 arranged and routed along the multiple joints of the robotic arm 1. The multi-jointed robotic arm 1 has multiple rotatable joints, enabling multi-angle or even full-angle rotation. The operating radius of the robotic arm 1 is greater than or equal to the maximum linear dimensions (length, width, and height) of the high-risk space. This allows the robotic arm 1 to cover the entire high-risk space, achieving comprehensive cleaning.
[0047] Furthermore, this embodiment also includes an electrically connected camera mechanism and imaging mechanism (not shown in the figure); the camera mechanism, such as an industrial camera, is installed at the end 12 of the drive assembly to capture real-time images and transmit the real-time images to an imaging mechanism such as a display screen located outside the high-risk space, so that workers can observe and operate outside the fluidized bed.
[0048] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will appreciate that the present invention is susceptible to various modifications and variations. The embodiments and features of the embodiments of this application may be combined arbitrarily without conflict. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
