Definitions
- the invention relates to a device for conveying sludge, in particular for cleaning the swamp areas of underground mining, i.e. for picking up the sludge from the bottom and for intermediate transport underground, with a moving device with a clearing blade and a pump which is connected to a delivery line.
- the invention has for its object to provide a mobile sludge pick-up and transport device with which sludge with a high solids content can be manipulated.
- the moving device is designed as a mobile unit and has a lifting and lowering loading shovel, on the inside of the rear wall a transverse! i egende transport screw is arranged, the delivery end point of which is the opening of the suction pipe of the pump designed as a high-pressure piston pump and that above the transport screw, a ramming device acting on the sludge in the screw and having a tamper is provided.
- Such a pumping system or device can be used in a variety of ways because it represents a mobile unit, that is to say it can be used both in the proposed swamp section and in other swamp sections or in other areas.
- the lifting and lowering loading shovel enables the sludge to be picked up safely and fed via the screw conveyor on the rear wall to the high-pressure piston pump with controlled valves, via which the sludge is then fed directly into the trolley via the conveyor line.
- the ramming unit ensures that optimum mixing of residual water and solid remaining in the solid is achieved and the formation of bridges is prevented. As a result, a sludge with a high solids content reaches the high-pressure piston pump and then the trolley.
- a good Mani pul i erbarkei t of the device is ensured that the loading shovel is rotatably arranged at the free end of a support arm which in turn is pivotally mounted on the moving device. In this way, the loading shovel can be brought into a position where it can safely pick up the mud lying on the track sole, regardless of how thick the layer is. The loading shovel lies effectively on the track bottom and thus pushes safely into or under the mud layer.
- the mud is picked up particularly evenly and, on the other hand, very securely because, according to the invention, the loading shovel is held by a link mechanism formed by the support arm and supporting ropes, the supporting sheave 1 e of the loading shovel being struck by means of turnbuckles giving a variable inclination.
- the tip of the loading shovel automatically hits the track bottom, the sludge layer then being pressed into the shovel by moving the moving device forward. Since the loading shovel is suspended from the supporting cables, it can 6211
- the loading shovel is held optimally in each case via the handlebar gear so that the sludge is safely taken up and pushed through to the screw conveyor in order to be grasped by it and transported onward.
- the len gear is completed to a four-bar linkage in that the support cables run above the support arm and are articulated accordingly above its pivot points on the moving direction and on the loading shovel.
- the loading shovel thus forms, on the one hand, and, on the other hand, the spacer between the pivot points which are assigned to the moving device, the four-bar joint together with the support arm and support cable.
- Such a four-bar linkage is stable and precisely adjustable, so that overall a very advantageous device is created.
- rammers are, as already mentioned above, distributed over the length of the screw conveyor. These fulfill their function in that they are semicircularly curved and are assigned to a shaft designed as a crankshaft with a connecting rod, which runs above the rear wall and that the tamper foot is configured in the longitudinal slot to be close to the transport screw. It may be advantageous if the shaft is connected to the drive of the screw conveyor, preferably via a second outlet.
- the transport screw is assigned an additional nozzle, preferably in the form of a tube equipped with openings and nozzles, which runs above the longitudinal slot. This makes it possible to specifically dilute the sludge to such an extent that it reaches the pump with an approximately 75% concentration.
- the device according to the invention is particularly mobile when the travel device is a crawler track. It is similarly mobile and location-independent if the moving device is formed by transport trolleys which can be moved on an EMS rail, in both cases the sludge pickup and sludge transport device being attached to the actual moving device. In the case of the crawler track, the traversing device can be moved freely on the track floor and can therefore also be used at any other place of use, while the cats that can be moved on the EMS rail have to be taken into account on routes where appropriate rails are or can be laid .
- the device is therefore very versatile and, as already mentioned, advantageously not only to be used underground but also in the surface area.
- the invention is characterized in particular by the fact that a device is created with which it is possible to safely take up the sludge deposited in the bottom sections, to feed it to a pump with a high solids concentration and well mixed, and to transfer it from this pump to the trolley or to the shaft to bring from where the sludge is then transported on trolleys. It is particularly advantageous that such a device allows a swamp section to be cleared and cleaned in a very short time without further treatment.
- the Schi ammateri al has a solids content of up to 75%, so that the sludge even is ultimately transportable on conveyor belts.
- Fig. 3 shows a loading shovel in side view and enlarged view and Fig. 4 shows the arrangement of the tamper.
- a loading shovel (7) is connected to the crawler chassis (3) or the displacement device (2) via a support arm (6), the support arm (6) simultaneously carrying a pump (8), via which the in the loading shovel (7) collected goods are sucked through the suction pipe (9) and then pressed into the delivery line (4).
- This material is sludge with solid particles of different sizes.
- the suction pipe (9) ends in the area of the transport screw (lo), which is arranged lying in the loading shovel (7) in its longitudinal axis.
- the suction pipe end (12) is arranged with its opening (13), so that the material brought in by the screw conveyor (lo) in an advantageously mixed and mixed form into the pump (8) designed as a high-pressure piston pump. Due to this uniform mixture, a uniform and high Given funding.
- the screw conveyor (lo) is set in rotation by the drive (15), the screw conveyor (lo) rotating in a tube (18) formed by the rear wall (16) and the loading surface (17) of the loading shovel (7).
- This tube (18) has a longitudinal slot (19) through which the sludge enters the tube (18) in order to then be moved forward by the screw conveyor (lo) in the direction of the conveyor end point (11) and thus the suction tube (9).
- a ramming unit (20) acts in the longitudinal slots (19) and has several rammers (21) distributed over the length of the loading shovel (7). These rammers (21) are rotatably connected to a shaft (22) designed as a crankshaft (22 l ) with a connecting rod (22 11 ) and arranged above the rear wall (16).
- the shaft (22) can be connected to the drive (15) via the second output (23) in such a way that the rammers (21) are raised and lowered one after the other.
- an additional nozzle (25) can be switched on, which runs above the longitudinal slot (19) in the form of a water pipe, into which holes (not shown) are formed with nozzles.
- Fig. 3 illustrates that the tubular rear wall (16) and a wedge-shaped attachment (3o) on the loading surface (17) through its curved rear wall (31) an advantageous cladding tube (18) for the screw conveyor (lo) is created .
- the wedge-shaped attachment (3o) can optionally be moved slightly on the loading surface (17), so that the volume of the sludge to be transported by the screw conveyor (lo) can be changed slightly, depending on its solids concentration. It is easier to adjust the speed of the screw conveyor.
- the inclination of the loading shovel (7) can be changed in a simple and expedient manner via the support cables (33, 34) or turnbuckles arranged therein. These support ropes run essentially parallel to the support arm
- Fig. 1 shows the rest by the dash-dotted line, the position of the loading shovel (7) when swinging touching the track sole (5) takes egg. lo
- 2 shows the path of the sludge picked up by the loading shovel (7) by arrows (43, 44, 45). 2 shows the arrangement of the different tamper (21, 41, 42) with their tamper feet (26) each of the same design. That the Stampferf ' ⁇ ße (26, 26' 26 '') Whole can cover the longitudinal slot (19) largely or influence, so that bridge formation is reliably prevented is clear here.
- a shut-off valve (47) is provided in the suction pipe (9) in front of the pump (8) and a fresh water valve (46) is provided on the pump (8). These are indicated accordingly in FIG. 1. With the shut-off valve (47) closed, the pump (8) and the downstream delivery line can be rinsed and cleaned with fresh water before a break in operation. It is also advantageous to fill the pump (8) with fresh water before starting again in order to facilitate the starting of the pump (8).
