A ventilation system and method for a cold planer are provided. The ventilation system includes a settling box inside a water tank. The settling box includes a body. The body includes at least one sidewall defining an air inlet having a first cross-section to accept dust and fumes generated by a milling drum operation of the cold planer but to reject particles from the milling drum operation at or above a predetermined size. The settling box further includes an air outlet having a second cross-section less than the first cross-section of the air inlet. The ventilation system further includes an outlet pipe connected to the air outlet, a fan and a cleaning system. The fan is configured to pull air from below the air inlet into the settling box, through the air outlet and to the outlet pipe.

A system for automatically cleaning and washing an ice cream machines includes a liquid container for storing raw materials; a freezing cylinder connected with the liquid container through a cleaning pathway; a water tank for storing rinse water to rinse the freezing cylinder and the cleaning pathway; a detergent tank for storing detergents to clean and wash the freezing cylinder and the cleaning pathway; a pump arranged on the cleaning pathway to selectively pump the raw material, the rinse water or the detergent; and a control panel adapted to control an on/off and cleaning.

Many conveying units for media capable of flow are used for products that are harmful to the environment and at least attack the conveying units themselves over time or deposit in them and clog them. Cleaning of the conveying units is therefore recommended, but such cleaning represents an effort that is preferably not made, because of the effort involved. Against this background, an apparatus for cleaning of conveying units, which apparatus can run both in simple manner and practically without supervision, uses a cleaning circuit in which the conveying unit to be cleaned is short-circuited with a cleaning agent tank and thereby constant circulation of cleaning agent through the conveying unit to be cleaned is pumped and the unit is thereby cleaned.

A cleaning apparatus for an internal bore formed in a feeding tube has a shaft with a distal end and an opposing proximal end. The distal end terminates at a blunt tip and the proximal end terminates at a cap. The shaft has a length such that when inserted into the feeding tube, the cap aligns with a proximal end of the feeding tube and the blunt tip extends only partway out of a distal end of the feeding tube. At least one disc is mounted on the shaft adjacent the blunt tip. Each disc has a diameter equal to or greater than said first diameter of the internal bore so that tip portions of the disc deflect and travel along the internal bore of the feeding tube providing a squeegee-like cleaning action.

A flexible paint hose has a first end, a second end, and a continuous conduit wall extending from the first end to the second end. The continuous conduit wall has a cross-section absent of an edge, and a non-circular cross-sectional shape in a first state and a substantially circular cross-sectional shape in a second state.

A descaling method involves a tool for diagnosing the engine of a motor vehicle, which tool can interact with the control electronics system of the engine, not only for reading information and controlling certain members during a hydrogen injection cleaning procedure, but also for checking, in real time after cleaning, the state of the impacted members and updating the engine management parameters accordingly in the control electronics system. Thus, the electronic management of the engine may take account of the resetting (i.e. to the initial values or values close to the initial values) of the operating parameters of the engine which are sensitive to engine scaling, such as EGR valve mobility, valve lift, DPF clogging, injector needle mobility, etc.

System and method for removing scale of a sewer pipe using microbial mist type spray, the system including a microbe storage tank to store liquid microbes; a chamber connected with the microbe storage tank through an injection pipe and supplied with a determined, metered amount of liquid microbes, if needing to spray liquid microbes into the sewer pipe; a metering pump provided on one side of the injection pipe, to supply power for injecting a metered amount of liquid microbes into the chamber; an air tank to store compressed air; a supply pipe to supply compressed air into the chamber when the liquid microbes are sprayed; a supply tube to allow liquid microbes having air cavities resulting from supply of the compressed air to flow; and a spray nozzle provided at an end of the supply tube, to spray liquid microbes in a mist form into the sewer pipe.

The invention discloses a method for individually assessing the cleanness of at least one of an upper (2) and a lower (3) bed support in a process column (1). The method comprises the steps of: a) providing a process column (1) comprising an upper (2) and a lower (3) bed support, a column chamber, a movable adaptor (5), an upper outlet (6) and a lower outlet (7); b) conveying liquid through one of the lower (3) and upper (2) bed supports, e.g. by moving the adaptor (5) downwards at a predetermined rate with one of the upper and lower outlets closed and the other open to force liquid through one of the lower and upper bed supports, and; c) measuring the differential pressure over the bed support through which liquid passes.
