Definitions

  • the invention relates to a method for, in particular automatically, controlling liquid in a building material processing system, in particular for cleaning the building material processing system and/or for processing building materials using the building material processing system.
  • the invention also relates to a liquid system for controlling liquid in a building material processing system.
  • the invention also relates to a system with such a liquid system and with such a building material processing system.
  • Building material processing systems typically have several components that come into contact with building material one after the other during building material processing.
  • a flow of building material is usually passed through the building material processing system, with the components that come into contact with the building material one after the other being arranged in the flow of building material in the manner of a series connection. If such a building material processing system is to be cleaned, said components are usually exposed to cleaning fluid in the same order in which they come into contact with building material during building material processing.
  • the components of such a building material processing system are typically exposed to fluid for cleaning in the order that corresponds to a natural, gravity-driven flow of the fluid.
  • a method according to the invention is used for, in particular, automatic, control of liquid in a building material processing system, in particular for cleaning the building material processing system and/or for building material processing using the building material processing system.
  • the building material processing system has at least two components. Each of the components has a contact surface, wherein the contact surfaces come into contact with building material, in particular in the form of thick material, one after the other during building material processing.
  • a flow of building material can be guided through the building material processing system in which the components are arranged one after the other in the manner of a series connection.
  • "One after the other" in this context can mean that a portion of the flow of building material moving in the flow comes into contact with the components one after the other.
  • a first of the components has a building material pump for conveying building material.
  • a second of the components has a conveyor line for transporting building material out of the building material processing system. By means of the conveyor line, building material can be transported out of the building material processing system into a, in particular formwork, casting mold.
  • the method comprises applying a first liquid to the first component in such a way that the contact surface of the first component comes into contact with the first liquid.
  • the method also comprises applying a second liquid to the second component in such a way that the contact surface of the second component comes into contact with the second liquid.
  • the application of the first component overlaps in time, in particular in parallel, with the application of the second component.
  • the components can be applied with liquid in a different order than they come into contact with building material during building material processing.
  • the sequence in which the components are exposed to liquid may deviate from a natural, gravity-driven flow of the building material or liquid.
  • control can mean “steer” and/or “regulate”.
  • the building material is preferably a thick material.
  • the thick material can be a paste-like mixture of different materials.
  • the thick material can be mortar, cement, screed or concrete, each in a mixable and/or conveyable state. In the mixable and/or conveyable state, the thick material has not yet hardened or set.
  • the loading of the components is monitored, in particular controlled, by means of a common electrical control device, in particular a control device.
  • the common electrical control device can be a central control device. Error-prone communication between several control devices can thus advantageously be avoided.
  • a fresh liquid in particular fresh water
  • a fresh liquid is used at least partially as the first liquid and as the second liquid.
  • a fresh liquid in particular fresh water
  • a service liquid in particular service water
  • the use of fresh liquid allows for particularly effective cleaning.
  • the use of service liquid proves to be advantageous from an ecological point of view. In particular, the use of service liquid results in particularly low liquid consumption when carrying out the process.
  • the second component when the second component is exposed to the second liquid, the second component is additionally exposed to the first liquid in such a way that the contact surface of the second component also comes into contact with the first liquid or a mixture of the first liquid and the second liquid.
  • the supply of fresh liquid is carried out by means of a nozzle device.
  • the nozzle device is assigned to one of the components and arranged at a free distance from the contact surface of this component such that this component is supplied with the fresh liquid across the free distance.
  • the fresh liquid can be accelerated by means of the nozzle devices, which enables particularly thorough cleaning.
  • Such a nozzle device can have one or more nozzle openings.
  • Such a nozzle opening preferably has a cross section of 0.5 mm 2 to 500 mm 2 , in particular 1.5 mm 2 to 50 mm 2 .
  • a pressure of the fresh liquid of 0.3 MPa to 25 MPa, in particular 1.5 MPa to 2.5 MPa, can drop across the nozzle device.
  • the first liquid and/or the second liquid are at least partially collected as used liquid after the first component and/or second component have been acted upon.
  • very little or even no liquid is lost.
  • the second liquid is prepared, in particular filtered, before the second component is applied.
  • the second liquid is temporarily stored in a liquid tank before the second component is applied.
  • the second liquid can be calmed in the liquid tank in order to separate particles and/or foreign substances carried by the second liquid, in particular due to gravity. In particular, such particles and/or foreign substances can float in the liquid tank or settle on the bottom of the liquid tank. The more thoroughly the second liquid is prepared, the better its cleaning effect when the second component is applied.
  • the second liquid is at least partially circulated in the building material processing system.
  • the second component is preferably placed in a service liquid circuit for the purpose of being supplied with the second liquid. By circulating the second fluid, fluid consumption during the procedure can be reduced.
  • the building material processing system has at least one further component, the contact surface of which comes into contact with the building material before or after the contact surface of the first and/or second component during the building material processing.
  • the contact surface of this further component is exposed to the first liquid before, after or at the same time as the first component.
  • the contact surface of this further component is exposed to the second liquid before, after or at the same time as the second component. If the further component is exposed to liquid in parallel to the first two components, premature hardening of the building material on the further component can advantageously be avoided.
  • a prioritization can also be carried out that determines whether the further component should be exposed to liquid before or after the first and/or second component. The latter case proves to be advantageous if the further component, in contrast to the first and/or second component, can be replaced more cost-effectively or can be freed of hardened building material more cost-effectively.
