A conveyor belt cleaner system comprising a platen subassembly positioned transversely of the return path of the conveyor belt; a steam chamber disposed adjacent a first portion of the conveyor belt, the steam chamber including a steam header; a vacuum chamber adjacent the steam chamber and disposed adjacent a second portion of the conveyor belt, the vacuum chamber having an outlet connectable to a source of vacuum; a first belt wiper in wiping defining an entrance to the steam chamber; a second belt wiper having a discontinuous wiping surface defining a septum between the vacuum and steam chambers; a third belt wiper defining an exit from the vacuum chamber; and apparatus including a rotatable bolt cooperative with the steam header to vary the width of steam application from the steam header onto the conveyor belt in accordance with a width of conveyor belt presented to the conveyor belt cleaner system.

A LiDAR sensor may include: a housing; a window cover installed on the housing; a motor mounted in the housing; a rotating shaft rotated by the motor; a guide connected to the rotating shaft and rotated along the surface of the window cover; and a brush mounted on the guide so as to face the window cover, contacted with the window cover, and washing the surface of the window cover with rotation of the guide. The guide may include: a first guide part connected to the rotating shaft; a second guide part rotatably connected to the housing; and a third guide part connected to the first and second guide parts, formed in a U-shape so as to face the window cover, and having the brush mounted thereon.

A cleaning device 2 is for performing a preliminary cleaning step 110 to a cleaning step 120 of a cleaning method 100, and includes a preliminary cleaning tank 11 containing a preliminary cleaning agent LQ1, a cleaning tank 12 containing a cleaning agent LQ2, an outer container 21 containing the preliminary cleaning tank 11 and the cleaning tank 12, a temperature adjustment unit 30 for adjusting the temperature of water WT contained in the outer container 21, an ultrasonic unit 40 for applying an ultrasonic wave to the water WT, or to the preliminary cleaning agent LQ1 or the cleaning agent LQ2 through the preliminary cleaning tank 11 or the cleaning tank 12, and a controller 80 controlling each of the units.

An insert assembly for a foam generating device includes a first insert and a second insert with a channel defined therethrough. Inserts may be formed by two shell halves that are coupleable to one another to define the channel. A plurality of ribs extends along an interior surface of the channel. Pad structures defined by porous media are provided in the channel and gripped by the plurality of ribs. The pads receive cleaning solution passing through the channel and cause foam to be generated by breaking-up the cleaning solution and agitating. The ribs may be arranged horizontally relative to a longitudinal axis of the insert assembly and retain the pads within the device. Inserts may be arranged in series along a longitudinal axis of the foam generating device with the pad structures arranged within the channel.

A device for cleaning an end face of an optical fiber may apply a vacuum to a solvent tank, where the device includes a vacuum generator to apply the vacuum and the solvent tank. The device may receive, from a solvent reservoir and in response to applying the vacuum, solvent with the solvent tank. Additionally, or alternatively, a device for cleaning an end face of an optical fiber may apply a pressure to a solvent reservoir, where the device includes a pressure port to apply the pressure and a solvent tank. The device may receive, from the solvent reservoir and in response to applying the pressure, solvent with the solvent tank.

A method of cleaning for a chemical mechanical polishing system includes directing a gas that includes steam from an orifice onto a component in the polishing system while the component is spaced away from a polishing pad of the polishing system to clean the component, and moving the component into contact with the polishing pad.

A method for inhibiting a flash point of trans-1,2-dichloroethylene (T-1,2-DCE) and a use of T-1,2-DCE are provided. The T-1,2-DCE has an excellent cleaning effect and is environmental friendly but cannot be used alone because of huge safety hazard caused by its low flash point. 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd) is used to inhibit the flash point of T-1,2-DCE. However, because the actual boiling points of these two substances are quite different, the two substances are easily separated at a slightly-high ambient temperature. Because a boiling point of HCFO-1233zd is extremely low, HCFO-1233zd will escape rapidly, resulting in the loss of inhibition on the flash point. In the present disclosure, T-1,2-DCE and 1-chloro-2,3,3-trifluoropropene are mixed to prepare a mixed solution, and the mixed solution can effectively maintain the inhibition on the flash point of T-1,2-DCE in various ambient temperatures, such that the T-1,2-DCE can be heated to generate a steam for cleaning.
