Definitions
- the invention relates to a material feed container for two-cylinder Dic material pumps of the type specified in the preamble of claim 1.
- Material feed containers of this type which have an upward-pointing material feed opening, for example for the connection of a material feed line, two conveyor cylinder openings arranged on an end wall and surrounded by wear glasses, and a pressure connection through the container wall for connection to a feed line.
- Such containers are usually cleaned and serviced from above through the material feed opening. Apart from the fact that the removal and installation of the pipe switch via the material feed opening is difficult, the material feed opening in those cases in which a feed line is directly connected is only accessible after this line has been disconnected.
- the invention is based on the object of developing a material feed container which is easily accessible for cleaning, maintenance and repair purposes even in the case of stationary installation in confined spaces, without the lines for the material feed and for the material removal having to be removed .
- the invention is based on the idea that at least one of the side walls of the material feed container, optionally equipped with the agitator, is relatively freely accessible on the outside even in the case of a stationary installation in narrow spaces, especially since the agitator motor provided there is serviced from time to time requirement.
- at least one side wall part equipped with an agitator is designed as a closure flap, and that the agitator is opened when the closure flap is opened the cleaning and maintenance opening in question can be pivoted out of the interior of the container. This will completely expose the agitator for maintenance purposes.
- the pipe switch is easily accessible through the maintenance opening without obstruction, and without having to dismantle other container parts or the conveyor lines connected to the container.
- the closure flap can be pivoted about an essentially vertical axis on the material feed container.
- the side wall containing the maintenance opening is expediently oriented substantially vertically.
- closure flap is pivotally connected to the material feed container via an additional pivoting mechanism.
- a hydraulic motor is flanged onto the outside of the closure flap, the drive shaft of which extends through the flap and is preferably double-mounted in the flap and carries the agitator on the side opposite the hydraulic motor.
- the agitator can be designed as a screw conveyor that constantly transports the material to be conveyed inside the container towards the feed cylinder openings. In principle, however, it is also possible to use pure paddle agitators which, without the aid of a conveyor, only serve to loosen or mix the material in the container. The invention is explained in more detail below with reference to the exemplary embodiment shown schematically in the drawing. Show it
- FIG. 1 shows an end view of a material feed container
- FIG. 2 shows a rear view of the material feed container according to FIG. 1;
- FIG. 3 shows a plan view of the material feed container with the closure flap open
- FIG. 4 is a view in the direction of arrow A of FIG. 3rd
- the material feed container 10 mounted on a pedestal 12 is part of a two-cylinder thick matter pump, the feed cylinder 14 of which is connected to the material feed container via feed cylinder openings 16 in the end wall 18.
- a pressure connection 22 On the rear wall 20 of the material feed container opposite the end wall 18 there is a pressure connection 22 to which the delivery line 24 of the thick matter pump is connected.
- a pipe diverter 26 designed here as an S-tube, which is connected at one end to the pressure connection 22 and the other end of which can be pivoted alternately about the axis of the pivot shaft 28 with the aid of a hydraulic cylinder in front of the two delivery cylinder openings 16.
- the pipe switch 26 has a wear ring 28 at its cylinder end, which can be displaced on a wear glasses 30 arranged in the area of the feed cylinder openings 16.
- the side walls 32 of the material feed container 10 contain a maintenance opening 33, which is opened by a Container 10 hinged flap 34 can be closed.
- the closure flaps 34 are connected to the container 10 via a swivel mechanism 36.
- Agitators 36 driven by a hydraulic motor 40 are also rotatably mounted on the closure flaps 34 about a horizontal axis 38.
- the agitators are designed as screw conveyors which mix the viscous material arranged in the container 10 and at the same time convey them to the feed cylinder openings 16.
- the material feed container is charged via the material feed opening 42, possibly via a filling funnel 46 which can be placed on the flange 44 or via a material feed line (not shown).
- the agitator 36 is also folded out through the opening 33 and can be serviced there without difficulty.
- the pipe switch 26 and the wearing parts 28 and 30 are also freely accessible through the maintenance opening 33.
- the S-tube 26 can be removed from the container rear wall 20 and removed through the maintenance opening 33 or exchanged for a new S-tube.
- the pressure port bearing is designed as a flange bearing that can be dismantled inwards and a separable pivot shaft 28 is provided.
