Definitions
- the invention relates to a device for cleaning a tank, z. B. a tank truck or a storage tank and this device procedure.
- a device for cleaning a tank, z. B. a tank truck or a storage tank and this device procedure.
- it refers to tanks in which Waste is collected, in particular it is waste, that are environmentally harmful. Examples of this are waste materials from the chemical industry, especially the petrochemical industry and the paint industry. It continues to refer to tanks in which products, for example oil.
- the tank trucks are trucks that are equipped with a tank that typically holds 8 - 20 m 3 .
- the trucks are connected directly to the tank, for example, or they are designed as semi-trailers.
- the storage tanks are tanks with a volume that can be in this area, but can be smaller or larger.
- waste disposal in the normal workflow of a waste disposal company incur different loads different waste materials have to be transported.
- the tank of the tank truck must be cleaned after each trip.
- Product tanks also have to be cleaned from time to time.
- Some tanks have a piston-shaped stamp, which can be moved axially along the entire tank and while sliding along the tank walls. In this way, the tank walls getting cleaned.
- the tank can be tilted relative to the vehicle the vehicles are then called tippers.
- the tank is on raised at its front end or in the vicinity thereof, in particular takes place this with a hydraulic cylinder / piston unit. Received when lifting the tank is tilted. After opening the back cover is again the entire internal cross-section is free, the tank can be cleaned.
- the invention has set itself the task of a device to indicate a low-emission cleaning of a tank of a Tanker truck allows. Furthermore, it has the task of the invention made to specify a method using this device low-emission cleaning of a tank truck tank permitted.
- the task is solved by a method for low emissions Cleaning a tank using the above contraption with the following steps: The valve is closed, the flange is on the The outlet nozzle of the tank is attached, the valve is opened and the cleaning lance is introduced through the outlet nozzle into the tank, cleaning liquid is under high pressure via the high pressure line of the cleaning lance supplied and targeted via the control device, the injection unit moved so that an exit jet of the cleaning liquid from the at least one nozzle of the injection unit in succession in different Direction points, gradually the entire inner surface of the tank the cleaning liquid loaded with product residues is collected through the discharge hose is preferably discharged passed into a receiving tank.
- the tank is no longer cleaned on the open tank, but instead in a closed tank and only over the outlet connection.
- the outlet port serves on the one hand as a passage of the cleaning lance and on the other hand draining off the cleaning liquid that comes with the removed product residues is loaded, and any product residues.
- the tank won't more open, it remains closed. This will find the cleaning process in a closed area, namely in the closed Tank instead.
- a hazard to people who operate the cleaning lance is no longer given. Rather, the cleaning lance is now working completely in the shielded area. She also works that one Operator is not immediately required. It is constructed in such a way that they are not accidentally pulled out of the sealed passage can.
- the cleaning liquid is under very high pressure supplied, the pressure can be over 1000 bar. At such high pressures a risk to the cleaning staff is possible. A direct one Contact with the cleaning fluid under such high pressure leads inevitably to injuries.
- the invention has the Advantage that now the cleaning liquid and product to be disposed of can be collected collectively. They will be in the drain hose derived. This can, for example, be connected to a receiving tank in which the entire cleaning liquid including the product residues into flow. The freighted liquid collected there can then be worked up later. It is now possible to to control the amount of cleaning liquid used because the entire cleaning liquid used for cleaning now in Receiving tank is accumulated and its liquid content with simple Funds can be recorded.
- the injection unit can be controlled via the control device.
- About a suitable one Control can target the entire inner surface of the tank with the cleaning liquid can be reached and processed. This process can be mechanically controlled, in particular automated.
- the branch piece is a section of the discharge hose and is the tight passage for the rigid
- the lance shaft is attached to this section of the discharge hose.
- lance and drain hose must clear the free Split the passage of the tank outlet port.
- Stub to the section of the discharge hose that forms the branch piece Stub used, which carries the passage for the lance shaft receives a simple construction that does not require the drain hose again to have to be connected separately, as is the case with a separate branch the case is.
- the tight passage for the lance is designed so that it the lance shaft sealingly encloses, but that the lance shaft can be moved back and forth is, in particular can also be rotated.
- the lance shaft be plugged into the tight passage. For this it is necessary To clear the lance at one end, in particular at the rear end the high pressure line for the cleaning liquid to decrease. But it is also possible to have the injection unit at the front end to remove. However, this must be done very rarely or only once the lance with the branch piece or even connected to the drain hose. It is therefore only for repairs necessary to separate the lance from the branch.
- the tight passage can also be designed so that not immediately the lance shaft is sealed, but an additional one Guide tube is provided by the lance shaft.
- the guide tube is sealed on the outside against the tight passage, while sealingly enclosing the lance shaft.
- the spray nozzle unit has a rotatable one trained arm, arranged at its free end at least one nozzle is. It preferably has two at an angle of 180 ° to one another Arms, each with a nozzle at its free end.
- the arm is there pivoted about an axis which is transverse to the longitudinal direction of the lance shaft runs. In this way, the injection unit can be conveniently moved through the Outlet connector of the tank are inserted into the tank.
- the injection unit has a resting position, which she either occupies independently or into it is driven by the drive, and in which it is parallel to the lance shaft runs. In this way, the cross-sectional dimensions are small Lance in the rest position can easily be released from the outlet nozzle of the tank are pulled out without the risk that the injection unit crossways.
- the outlet connection is by a separate component is formed, to which the discharge hose is to be connected individually is.
- the branch piece then forms one together with the lance unit connected in normal operation.
- the control device has a transmission means, for example as a rod, rope or pressure hose is executed. It is connected to the lance shaft and preferably in arranged the guide tube already mentioned. About the transmission medium at least one movement of the injection unit is carried out, in particular a rotary movement about an axis transverse to the longitudinal direction of the Lance shank. The second rotary movement, in addition to the first one Detection of the complete solid angle is necessary, is preferred by turning the guide tube and / or the lance shaft that freely protrudes outwards from the tight passage.
- the rotary drive of the injection unit is mechanically designed so that an operator is not necessary for this. Basically, however The injection unit can also be driven manually.
- control means is provided near the section of the discharge hose, in order to be able to record how high the dirt content of the discharged Cleaning liquid is.
- This control means is, for example, as Sight glass, sampling valve or viewing area implemented. To this The respective intermediate state of cleaning can be monitored in this way.
- a tank truck is shown, the one Has tank 20.
- This tank is for holding liquid waste intended. So it's all about the transportation of polluting Liquids from a delivery point to a collection point. So that with different freight different products are not mix and trigger uncontrolled reactions, but also around To keep the tank clean overall is to clean the tank stand of the technique.

Furthermore, there is a denser branch piece 32 Passage 36 is provided for the lance shaft. This passage 36 is essentially in the axis line of the outlet connection 34, so that a through the passage 36 reaching lance into the interior of the tank 20 protrudes, as shown in Figure 1. You still do that Take advantage of the fact that the outlet port is slightly inclined, which means also the lance obliquely upwards into the interior of the tank 20 protrudes.
- the length of the lance is suitably dimensioned, for example it is between 1 and 3 meters long.
- the length itself is arbitrary. It just has to be achieved that the lance protrudes sufficiently deep into the interior, so that overall a uniform cleaning of the tank inner walls takes place can.
- control device 38 which controls the movement of the Injection unit 30 controls the lance.
- the injection unit 30 is at the front Arranged end of the lance shaft 28 and around this end about an axis 40 pivotable, which extends transversely to the longitudinal axis of the lance shaft 28.
- the Injection unit 30 has two arms 42 pointing in opposite directions to one another, which each carry a nozzle 42 at their free ends.
- the nozzle is directed that an exiting jet of detergent towards the Arms 42 exits.
- the nozzle jet is thus oriented at right angles to axis 40.
- the lance shaft 28 is additionally rotated by outside of the tank 20 at the end of the lance shaft 28 there a rotary drive 46 the control device 38 is provided, so gradually the entire Inside wall of the tank reached by the cleaning liquid.
- the two arms 42 of the injection unit 30 can be brought into a rest position in which they lie parallel to the lance shaft 28. In this condition the lance has the smallest cross-sectional dimensions in the area of its injection unit 30. In this condition, it can also pass through the outlet port 24 are inserted into and removed from the tank 20.
- the rest position is either specified by the control device 38 or else additionally or separately preloaded elastically.
- suitable spring means are provided, the two arms of the injection unit 30 As soon as there is no actuator, pull to the rest position.
- the swivel drive of the injection unit takes place 20 via a mechanical transmission means, which is designed here as a rod 48 is.
- a pin is arranged on one of the two arms 42, which is gripped by an eye connected to the rod 48.
- the Rod 48 can be moved back and forth in the sense of the double arrow.
- the injection unit 20 with its two extended arms 42 along the dashed double arrow swiveled through 180 °. You can on this Starting from the shown transverse position to the lance shaft 28 in a Position parallel to the lance shaft 28 are moved. In this position can the injection unit 30 with the lance shaft 28 from the outlet port 24 are pulled out and brought into it.
- the rod 48 is passed through the passage 36 in a suitable form.
