CS201570B1 - Dosing device for automatic cleaning and desinfection of milking machines notably in utilization of the acidic means - Google Patents

Description

The subject of the invention is a dosing device for the automatic cleaning and disinfection of milking machines, especially when using acidic compositions.

Various dosing devices are used for cleaning and disinfecting milking machines to determine the concentration of detergent and disinfectant in the concentrated state to the required amount of water. The most sophisticated method of dispensing disinfectant so far utilizes manual dispensing, for example, from a container fitted with a cap and connected to a disinfection device, the appropriate amount of disinfectant solution being conveyed by gravity to the tank. The main disadvantage of these embodiments is the need for manual control, the dosing accuracy being dependent on the care of the operator. Other known embodiments serve to overcome these disadvantages, wherein the metering device is provided with an inlet and an outlet valve and connected to a vacuum line. When the inlet valve is opened, a corresponding amount of disinfectant is sucked into the dosing device from the reservoir, the inlet valve is closed and the outlet valve is emptied by opening the outlet valve. A disadvantage of these embodiments is the considerable complexity and cost, in particular the control of the valves and their failure rate, the impossibility to change the dose size. They cannot be used for acidic disinfectants, especially nitric acid, as the vacuum will suck the acid vapors into the pump, causing corrosion and damage to the pump. For this reason, alkaline disinfectants are used more often for cleaning and disinfection of milking machines.

201,570 aminoeulfonic acid, which is supplied in powder form.

It is an object of the present invention to provide such dosing devices for the automatic reading and disinfection of milking machines, particularly when using acidic compositions, which largely eliminate the above-mentioned drawbacks and allow for varying the dose size of the disinfectant.

SUMMARY OF THE INVENTION In the wolf dispenser body, an adjustable pipe with a flexible member is placed by means of a seal and a nut, over which the adjustable control electrodes are provided, the dispenser body or lid being provided with a nozzle and a venting hole.

1 is a cross-sectional view of the dispensing device at the maximum dose set, and FIG. 2 shows a dispensing device at the minimum dose set.

The dosing device for automatic cleaning and disinfection of milking machines consists of a dosing body 1 provided with a neck 2 through which a tube 5 passes, which is sealed in the neck 2 by a seal 7 and secured with a nut 8. hose. The dispenser body 1 is closed by a lid 3, in which a nozzle 4 is provided for supplying disinfectant from a container (not shown) and a breather hole 9. The dispenser body 1 is provided with adjustable control electrodes 10, preferably passes through the lid 3 and locked in position A screw 12 may be provided on the body of the dispenser 1 to facilitate orientation of the determination of the dose size.

The dosing device according to the invention operates as follows: from a disinfectant reservoir (not shown), the disinfectant flows through the nozzle 4 into the body of the dispenser 1 under pressure or even by gravity until its level reaches the adjustable control electrodes 10 which give impulse to stop the inflow. Since the adjustable control electrodes 10 are positioned just above the adjustable tube 5 in the dispenser body 2, the flexible member 6 and part of the adjustable tube 5 in the dispenser body 2 are filled with disinfectant and subsequently disinfectant discharges through the flexible member 8 and adjustable tube 5 into a disinfectant (not shown). When filling and emptying the dispenser body 2, air escapes or enters through the vent hole 4. The entire cycle of filling and emptying the dispenser body 2 with the disinfectant is repeated according to the required number of doses.

If the dose is to be changed, for example by changing the disinfectant used, the nut 8 securing the adjustable pipe 5 in the neck 2 of the dispenser body 2 through the gasket 7 is moved to the new position and locked by tightening the nut 8. After loosening the screws 21 securing the adjustable control electrodes 10 from the lid 3, the control electrodes 22 are adjusted to the desired dose size and the screws 11 are locked in position. Filling and emptying of the dispenser body 1 with the disinfectant then proceeds as described above. It is obvious that for the proper functioning of the dosing device, the inflow of disinfectant must be greater than the outlet of the adjustable pipe 5, so that after filling of the pipe 5 the level can rise to the control electrodes 10 and thus give a signal to stop the inflow. For accuracy, it is preferable that the lower edge of the control electrodes 10 be provided just above the highest point of the tube 5 in the dispenser body 2.
