  • the invention relates to a system for lubricating, cleaning and / or disinfecting conveyor belts for containers, in particular for foodstuffs such as bottles, glasses, cans, bags and the like.
  • the system has at least one central metering station, which can be connected to a water line, for diluting a lubricant, cleaner or disinfectant concentrate, and several distributor lines, which are connected to the metering stations and lead to the places of use.
  • the containers for the food e.g. B. beverage bottles
  • conveyor belts in particular slatted belts, hinge chains and the like.
  • beverage bottles have to be transported from the unpacker to the washing machine, to the filler, to the labeling machine and to the packer.
  • the cleaning of the bottles, the filling and the labeling is carried out predominantly automatically.
  • the conveyor belts running at high speeds which are made of stainless steel or plastic, must therefore be lubricated with a chain lubricant, which is also called "belt lubricant".
  • the conveyor belts must also be cleaned and / or disinfected at more or less regular intervals.
  • the required concentration of chain lubricants depends on a variety of parameters, e.g. B. from the belt speed, the surface quality and the load on the belts. Depending on the place of use of the chain lubricant, different concentrations are therefore to be used.
  • the cleaning agents, disinfectants and belt lubricants are supplied by the manufacturers as concentrates and are applied to the conveyor belt in the food processing company, diluted with water at different concentrations depending on the place of use. B. sprayed. The solution then runs from the belt through a collecting device into a sewage sewer.
  • the preparation of the working solution with the desired concentration from the concentrate supplied by the manufacturer can be carried out in different ways.

  • internal transport of the concentrates to the respective locations and separate metering systems for each location are required.
  • the concentrates are diluted to the desired application concentration in a central metering station.
  • the use solution is then routed to the places of use via distribution lines.
  • the invention relates to the further development of such a central conveyor belt lubrication system. Different concentrations of the working solutions intended for the individual locations are possible, however, require several central dosing stations which convey the use solutions to the conveyor belts via separate distribution lines. This requirement necessitates additional expenditure on metering technology and installed pipelines.
  • the object of the invention is to develop a system for lubricating, cleaning and / or disinfecting conveyor belts which, with little effort compared to the prior art, enables a different concentration of the use solution for each place of use.
  • This object is achieved according to the invention in a system of the type mentioned at the outset in that a mixing valve which can be connected to the distribution line and the water line and can be set individually for each location and a pressure reducer connected upstream of each mixing valve is provided at each location.
  • a homogeneously mixed stock and thus also use solution is obtained.
  • the stock solution is namely produced with a relatively high concentration and a relatively low throughput, so that the metering pulse interval in the pipeline is considerably shortened, the miscibility of the concentrates in the pipe is improved and an online metering is thus made possible.
  • Elaborate and cost-intensive storage tanks for the preparation and mixing of the solution or costly dosing techniques can be omitted.
  • the pressure reducer connected upstream of the mixing valve in each stock solution and water supply line equalizes any pressure fluctuations in the feed systems. A constant mixing concentration after the mixing valve is achieved via the adjustable, defined pre-pressure ratio of the components to be mixed.
  • the effort required for the piping of the mixed water system according to the invention is low compared to the laying of several lines for the ready-to-use solution, since the mixed water can be obtained from existing rinsing water systems or from the fresh water network on site. In addition, only a single line system is required to mix several concentrations.
  • the use of different concentrations of the cleaning, disinfecting and belt lubricant concentrations is thus made possible.
  • the application concentration can be adjusted and changed on site at any time in order to meet the contamination requirements, the disinfection tasks and the specific belt lubrication requirements. Since the concentration of the working solution can be set individually for each place of use, the concentrates can be used more economically without overdosing or underdosing.

  • the specific conditions of the place of use are also decisive for the choice of this additional static mixer.
  • a manually or automatically actuable actuator on the mixing valve for setting the mixing ratio is advantageous.
  • the system can thus be adapted to changing operating conditions.
  • a backflow of the partial flows is prevented in that check valves are provided in the water connection and the stock solution supply.
  • the invention also relates to a method for mixing, cleaning and / or disinfecting conveyor belts for containers, in particular for foods, such as bottles, glasses, cans, bags and the like, a lubricant, cleaner or disinfectant concentrate being diluted with water in a central metering station , this working solution is routed to several locations and is applied there to the respective conveyor belt.
  • the concentrate is prediluted in the central metering station to a stock solution which has at least the highest concentration required at the place of use and is subsequently diluted with water to the concentration desired there at the place of use to get the working solution.
  • the stock solution must have at least the highest concentration desired at the place of use. However, it is particularly advantageous if the concentration of the stock solution is set to three to six times the concentration desired at the place of use.
  • a relatively small dosing center is set up in the chemical room and the stock solution is conveyed to the lubrication circuits at the transporters.
  • a mixing valve is assigned to each lubrication circuit. Different application concentrations for the different lubrication requirements are made possible and thus the different application and hygiene requirements of the conveyor areas are taken into account.
  • the method and the system according to the invention can also in the central production of cleaning and disinfection solutions and their use in the food industry for, for. B. "lost" foam cleaning tasks can be used.
  • a constant cleaning and disinfection solution is prepared as a stock solution, conveyed to the decentralized cleaning stations via a distribution line system and diluted there with water to the required use concentration via the mixing valve.
  • the concentration of the use solution can be set individually for each area of use and thus optimally meet the different cleaning and disinfection requirements.
  • Fig. 1 shows a process diagram for a belt lubrication system
  • Fig. 2 shows a process diagram for a central cleaning system.
  • the spray system for applying the belt lubricant in FIG. 1 is divided into different lubrication circuits according to the different conveyor sections. Seven lubrication circuits are provided here, each of which is supplied with belt lubrication solution via a supply line 1 to 7. So far
  • the invention offers the possibility of producing these concentrations as follows with less technical effort than before.
  • a stock solution is created via a proportionally proportional metering (pulse water meter 12 and metering pump 11) and supplied to the various lubrication circuits via a distributor line system.
  • the stock solution has a concentration, e.g. B. 1%, which corresponds to approximately 3 to 6 times the application concentration.
  • a mixing valve 13 to 19 is installed in this new method, which dilutes the stock solution created in the chemical room to the required target concentration with fresh water from a second branch line system 20.

Abstract

Un poste de dosage central, raccordable à une conduite d'eau, sert à diluer un lubrifiant, un nettoyant ou un désinfectant concentré. Plusieurs conduites de distribution raccordées aux postes de dosage mènent aux points d'utilisation. Chaque point d'utilisation est pourvu d'une vanne mélangeuse (13 - 19) raccordable à la conduite de distribution (52) et à la conduite d'eau (23) et est ajustable individuellement pour chaque point d'utilisation. Il est également prévu un réducteur de pression (50, 51) monté en amont de chacune des vannes mélangeuses. Ce procédé permet d'obtenir une concentration différenciée pour chaque point d'utilisation (31-37), sans impliquer de complexité technique.
