The closing unit is operated by a pneumatic drive.

Description

The invention relates to a discharge device according to the preamble of claim 1.

Such discharge devices are used for emptying silo containers in a vehicle for the transport of bulk material.

Such a vehicle is in the EP 1 065 100 B1 or the DE 600 27 643 T2 shown and described. To quickly discharge the material, a dispensing tube is connected to a compressed air device. Dispensing funnels are arranged on the dispensing tube and are connected to the dispensing tube via closable openings. To close a valve-like closure member is used, which sits in the dispensing funnel. By varying a setting height of the closure part a throttling of the material flow rate is adjustable. The closure part has a valve bottom with an outer edge.

From the EP 0 586 752 B1 is a vehicle and a method for bulk transport with multiple containers known complete their emptying hopper with closure parts. Below the closure members, transducers are arranged in the form of a rotary flap valve. These are installed in a drain pipe.

The EP 0 292 031 B1 teaches to use a vehicle for the transport of bulk goods, the vehicle being designed as a semitrailer with semi-trailer. The vehicle can also be designed as a rail vehicle. The vehicle has several discharge hoppers with hermetically sealed discharge openings and shut-off devices, which are connected to a common discharge pipe. The obturator has a cutting edge for crushing chunks or lumps of bulk material.

The EP 0 043 386 A1 relates to a vehicle for the transport of powdered, granulated or fragmented material with multiple containers and their discharge openings with shut-off devices. The obturator consists of a conical cap, which is followed by a cylindrical ring, in which a circumferential groove for receiving a sealing ring according to the invention is formed. This rubber sealing ring is intended to ensure a hermetic closing of the discharge openings.

In the DE 10 2007 036 942 A1 an outlet device of a container for dusty or granular bulk material is presented. The container goes over at the bottom in a funnel-shaped outlet body. The outlet body opens into a shut-off device, in the form of a butterfly valve. At this a lever is attached.

Another from the EP 1 362 802 B1 known device is provided for a silo container with an attached silo tank bottom. This has an entry opening and arranged at the bottom of the container discharge. The discharge opening can be closed by a flap, which can be pivoted via a drive.

Also for a silo container, the closure device according to the DE 296 21 926 U1 , In this closure device is an outlet pot for a silo vehicle with a sliding sliding lid, which is moved by a pivotable hinged toggle.

A truck with pneumatic unloading and loading device is already out of the DE 11 48 187 B known. The truck serves to transport flowable goods. To control the discharged flow rate serves a slide. A pawl lock holds the slider in any position.

The DE 20 2009 007 067 U1 also handles a remote indicator for a dump valve position on trucks. The outlet flap can be brought into different positions from open to closed, by means of a discharge flap drive. The remote display eliminates a linkage with lever, which is necessary for manual operation.

In addition, in the EP 1 544 137 B1 discloses a system for blowing out tank cars and silo vehicles and conveying the blown-up good over long distances. It is envisaged that the compressed air coming from a compressor will be split. One part is diverted to blow out the tank wagon or silo vehicle, the other part is used to convey the goods through the delivery line. For this purpose, it is necessary to arrange a controllable outlet flap in the outlet, which is adjustable differently.

Furthermore, the treated DE 20 2006 004 208 U1 a system for controlling an outlet flap of a loading silo. An outlet flap is pivotable between a closed and an open position, wherein a Sicherheitsabsperrvorrichtung certain positions of the outlet flap ensures.

The invention has for its object to provide a device of the generic type, with the one hand, a rapid, pressureless emptying of a bulk container is possible and on the other hand further emptying z. B. a compressed air discharge allowed.

This object is achieved by a device having the features of claim 1.

By the invention, not only an emptying of the bulk material along the discharge pipe or the horizontal central line is possible, as in the EP 1 065 100 B1 is described, but it is a direct drain possible without the compressed air or auxiliary power must be used. The bulk material can simply fall through both openings, ie through the opening at the discharge hopper and the bottom-near opening on the pipe, quasi vertically through the pipe, and be collected in a collecting device below the vehicle. The invention thus allows an optional emptying. An essential advantage of direct emptying is that at the same time several dispensing funnels deliver a material flow simultaneously or in parallel, whereas in the dispensing tube a single material flow is present.

It is not excluded that compressed air is blown into the silo containers in order to accelerate the direct emptying.

In principle, any closure element close to the floor can also be designed as a valve element or as a sliding element.

Further advantageous embodiments of the invention are characterized in the subclaims.

Thus, it is provided in an advantageous development of the device according to the invention that each closing element is designed as a pivotable lid and / or a bottom flap. This pivotal solution can be done by hinged movement of the flap and / or by other combined movements. Thus, in principle, a combined rotary and sliding movement in question. A flap solution has the advantage that blockage of the flap or impairment of the flap function by bulk material can be avoided. In addition, a flap movement by an actuator using leverages in a simple manner possible.

Therefore, each closure element or each closure flap for the outlet opening is preferably designed to be actuatable by an actuator. Conceivable are all types of drives, such as electric motor drives. Conveniently, however, pneumatic actuators are used, since the pipe can be connected to a compressed air device, since appropriate pressure is anyway available from the compressed air generating device for emptying or in towing vehicle available.

A further preferred embodiment of the invention is characterized in that the actuator comprises an adjusting means, which is hingedly connected to at least one lever element, wherein the lever element is fixed to a shaft which is mounted on the lid or the flap such that the Adjusting means in a first position by means of the lid or the flap closes the outlet opening, while in a second position, the outlet opening is released. By this lever element, a linear movement of a pneumatic piston can be converted into a rotational movement of the flap, with large forces can be used to stop material flow even in, for example, almost full silo container.

It is particularly advantageous if a locking function is present, which holds the flap in the closed position, even if the pneumatic drive is switched off. This function can be realized with little effort by each lever element is designed as a locking claw or a pawl, which has a lid or Klappenverriegelungsfunktion, in particular an incision of the lever member engages in a locking pin to the lid or the flap under lock hold, wherein the lid or Klappenverriegelungsfunktion is preferably carried out by an eccentric element. When closing the flap automatically locks the locking claw on the fixed pin.

In a further advantageous embodiment of the invention are two, d. H. at least two, lever elements are present, each lever element are preferably each attached to one end of the shaft connecting the two lever elements. This can be done with an actuator or pneumatic cylinder through the shaft, a uniform force transmission. It is conceivable that a pneumatic cylinder controls several flaps simultaneously via the same shaft.

It is advantageous if the shaft is fixed or rotatably mounted on two spaced mounting flanges, each mounting flange attached to the lid or the flap, in particular welded or integrally connected, such that the shaft is spaced from the lid or the flap is. As a result, on the one hand a stable connection of the parts possible and on the other hand, a suitable power transmission of the actuator and a closing and opening movement of the flap possible.

In order to be able to fix the flap, ie a lid, to the dispensing tube with "flap", it is favorable that one or more preferably two supporting elements are attached, in particular welded, wherein preferably at least one of the support elements, an eccentric z. B. carries with a coronal and / or tooth-like edge on which a locking pin is arranged, and / or supports a support means for an actuator. A support element can thus have different functions. One function is to provide a latching approach so that the latching function can be implemented. Another function is the fixation of a pneumatic cylinder indirectly to the pipe.

To achieve material flow through the central delivery tube by means of compressed air without interference from the valve, d. H. To provide a substantially circular or oval tube cross-section in the flap area, the flap has a substantially conformed to the outer surface of the discharge tube, curved shape.

According to a preferred embodiment, provision is made for the flap to have on its surface facing the outer surface of the tube a closure piece which can be pivoted into the opening of the tube for closing the opening in the closed state of the flap. wherein in the closed state of the flap, the surface of the flap rests against the outer surface of the tube.

So that no pressure loss occurs in the discharge pipe when the flap is closed, the flap and / or the closure piece is provided with at least one seal, so that the flap also hermetically seals the ground-level outlet opening under pressure.

It is also very advantageous that an inner surface of the tube in the region of the lid or the flap in the closed state has substantially no depressions. As a result, there is no air turbulence or material obstruction in the flap area, so that no energy losses occur in compressed air operation.

A preferred embodiment of a pneumatic drive is achieved in that the actuator comprises a pneumatic cylinder which is connected to the discharge pipe via a support means, preferably two retaining flanges, wherein the cylinder is provided with an adjusting rod for opening and closing the outlet opening. The arrangement is particularly robust.

An important measure is that the dispensing tube is connected or connectable to a compressed air device such that compressed air flows along the dispensing tube and in this case the closing element is held in the closed position, so that an emptying of the bulk material takes place exclusively through the dispensing tube. The closing element and the flap are designed so that they remain closed after pressure drop. As a result, either a horizontal emptying and vertical emptying of the bulk material is possible. During horizontal emptying, the bulk material flows through the discharge hopper into the central pipe or the delivery pipe and initially stays there. Then the bulk material is conveyed horizontally through the line by compressed air and the silo container emptied. During vertical emptying, the bulk material falls vertically downwards directly from the discharge hoppers.

An embodiment will be explained in more detail with reference to the drawings, wherein further advantageous developments of the invention and advantages thereof are described. In purely schematic views:

The device according to the invention 100 , in the 1 is shown for use in a vehicle for bulk transport. The vehicle is preferably a semitrailer with semi-trailer. This has a silo container, which includes one or more containers or container parts. Each container or container part has a funnel-shaped outlet part on the bottom side 10 , which is also known inter alia as a delivery funnel. The walls of the containers are bevelled to allow for better material flow. On the top of the container filling openings are present. In 1 is the outlet part 10 only partially shown, with a fixing ring 10a with screw mounting holes 10b can be seen.

Below the container is a common discharge pipe 11 , This can be connected to a compressed air device to effect a discharge by means of compressed air, wherein the bulk material along the tube 11 flows. Each funnel-shaped outlet part is via a discharge opening on the discharge pipe 11 connected. A front end of the pipe 11 has a connector for compressed air and its rear end has a discharge opening for the material. The discharge at the rear end of the pipe is connected via a shut-off valve to a coupling for a hose. A discharge hopper opening can be closed by means of a closure part. At the front end of the pipe there may be a connection part which is connected to a compressor via a hose, one or more valves and / or further elements. The delivery tube 11 has an inner diameter of z. B. 75 mm to 125 mm.

Such an embodiment can be modeled on the EP 1 065 100 B1 and therefore will not be shown in detail here. The principle is in 5 shown.

2 illustrates the outlet device according to the invention 100 for dust, grain or pellet-shaped bulk material for use in the transport vehicle, with at least one funnel-shaped outlet part 10 that with the delivery tube 11 connected is. The outlet part 10 has a conical downwardly tapering body to a narrower cross section.

The delivery tube 11 has at a the outlet part opposite lateral surface of the discharge pipe 11 at least one outlet opening 12 on that in 3 can be seen. According to 3 you can practically from above through the discharge opening and the example oval-shaped outlet opening 12 look directly from the top to the ground. The outlet opening 12 may be rectangular or circular or have a different shape. The outlet opening 12 gets in the bottom area of the delivery pipe 11 For example, cut out, punched or otherwise formed.

The outlet opening 12 is opened and reclosed by a closing element such that the bulk material in an open position of the closing element 13 from the outlet part directly through the outlet opening 12 may leak, wherein in a closed position of the closing element 13 leakage of the bulk material is prevented. The closing element 13 is outside the delivery pipe 10 arranged and covers the outlet opening in the closed position 12 completely, in particular airtight.

The outlet opening 12 may have an area of 50-200 cm ² and is z. B. elongated in the pipe direction or arranged.

The closing element is as a pivotable lid and / or a rotatable bottom flap 14 executed. In 2 Arrow A indicates the opening direction of the flap 14 , The opening movement of the flap 14 takes place in a hinge around the pivot point P1. As in 4 illustrated includes the elongated flap 14 several parts and / or sections 15 . 16 . 17 , These may be partially frame-like parts, with a seal, for. B. rubber seal, can be integrated. One of the sections is at most as large as the outlet opening 12 so that it almost fills the opening. Another, larger section overlaps the outlet opening 12 , as more clearly in 6c can be seen. The seal 58 ( 6c ) is a circumferential rubber seal.

The flap 14 is moved by a pneumatic actuator. This includes an actuating means 20 that with a lever element 21 or two lever elements 21a . 21b articulated is connected. Each lever element 21a . 21b is on a wave 22 attached, and firmly connected to this, for example, welded. This is in turn at the door 14 so stored, that is rotatably mounted, that the actuating means 20 in a first position with the help of the flap 14 the outlet opening 12 closes while in a second position the outlet opening 12 is released.

2 shows the outlines of a lever element 21 , This is designed as a locking claw. As a result, a lock or a Klappenverriegelungsfunktion is possible. As can be seen, the lever element 21 with a cut 24 provided so that a locking finger 25 arises. The incision 24 of the lever element 21 Automatically engages in a closed flap position locking pin 26 , in a position where the flap 14 closed or almost closed. In total there are two cones 26 available. In the 1 . 3 and 4 is the locking pin 26 to recognize on one or both sides.

The lever element 21 grab the pin 26 , shut the door 14 is kept under lock and key. This flap lock function is provided by an eccentric element 27 executed or improved, which carries the pin.

The two lever elements 21a . 21b each sit at one end of the shaft 22 , This connects the two lever elements 21a . 21b ,

To recognize are in 1 also two mounting flanges 28a . 28b , The wave 22 is namely at these spaced apart mounting flanges 28a . 28b rotatably mounted. Each mounting flange 28a . 28b is on the outside of the flap 14 attached, z. B. welded or integrally connected, so that the shaft 22 from the door 14 is spaced. The clear distance between the two mounting flanges to the flap 28a . 28b is z. B. ¼ to ½ of the pipe outside diameter. The distance between the mounting flanges 28a . 28b with each other is z. B. ½ to about twice as large as the pipe outer diameter of the tube 11 ,

The length of the flap in the pipe direction can be 1.5 to three times as large as the pipe outer diameter of the pipe 11 be. Their width can be ½ to 1¼ three times as large as the pipe outer diameter of the pipe 11 be.

Near a mounting flange 28a . 28b is in 1 each a support element 30a . 30b to see. At the delivery tube 11 , and on its outer surface are the supporting elements 30a . 30b attached, both each having an eccentric element 27 with coronal rim. On the eccentric element 27 is the locking pin 26 arranged. The locking pin 26 is with the eccentric element 27 firmly connected and protrudes through the corresponding support element 30a . 30b through an opening. Also illustrated 1 in that the support element 30a by means of support means or two retaining flanges 31 . 32 a pneumatic cylinder 31 fixed.

So that the central tube 11 along its length has a uniform as possible inside diameter, has the flap 14 a substantially the outer surface 11a of the delivery tube 11 adapted, curved shape, as in 2 is shown.

Important is also at the flap 14 and / or on the pipe 11 attached seal 58 , so that an airtight flap closure with the flap closed 14 is available. This is particularly relevant to a function of horizontal evacuation by means of compressed air.

2 also shows a retention approach and / or bearing approach 35 for the flap. There can be two storage approaches 35 to be available. Every stock approach 35 is with the pipe 11 firmly connected. P1 denotes this fulcrum, while P2 designates another fulcrum which represents the fulcrum 20 and the lever element 21a combines. With P3 is the pivot point for the lever elements 21a . 21b referred to with the shaft 22 matches.

The actuator includes the pneumatic cylinder 33 , This is with an adjustment rod 37 for opening and closing the outlet opening 12 provided and pivotally mounted about the pivot point P4. The adjusting rod 37 is part. of the actuating agent 20 ,

5 shows in principle the vehicle 40 that a cab 41 and a silo container 42 Has. Below the silo container 42 are several outlet parts 10 or devices 100 arranged, with the central tube 11 in the longitudinal direction of the vehicle 40 extends. Above the silo container 42 are several inlet openings 43 arranged for bulk material. Each outlet part 10 and each inlet opening 43 is assigned to a container, not shown.

The delivery tube 11 is with the compressed air device 44 connected. This sits between silo containers 42 and cab 41 , The compressed air flows in compressed air operation along the delivery pipe 11 , In this case, every flap 14 held in the closed position, so that an emptying of the bulk material exclusively through the discharge pipe 11 takes place, as arrow B shows. The bulk material but can pass through the invention also, as the arrows C, directly down without auxiliary power. A grid 45 can be an underground container 46 cover. The grid 45 can serve for personal protection, ie it prevents persons from entering the container 46 can fall. It also protects against the vehicle 40 can drive into the container. The bulk material is marked S. Other container solutions are also conceivable.

The 6a - 6g show the operation and other details of the preferred embodiment.

The 6a - 6c show an opening operation of the flap 14 , First, the opening 12 through the fold 14 closed, like 6a shows. The flap 14 is through the lever elements 21a . 21b , which can also be seen as locking pawls or claws locked. The at the pin 26 stuck latch prevents accidental opening of the opening 12 , The adjusting rod 37 is retracted.

The 6b shows how the adjusting rod 37 is extended and the latch releases, but the flap 14 not wide open. It can be seen that the lever element 21a turns around its axis of rotation (compare P3 in 2 ). 6c shows the fully extended adjustment rod 37 and the wide-open flap 14 ,

The 6c also illustrates a preferred embodiment of the flap 14 , The inner surface of the pipe 11 should as possible have no depression through the flap assembly when the flap 14 closed is. Therefore, the flap 14 in the opening 12 fitted, leaving a first inner surface 18 the flap 14 runs flush with the pipe inner surface. The inner surface of the pipe 11 is essentially smooth, which is advantageous for compressed air operation. A second, on the flap edge arranged (the pipe facing) inner surface 19 is in surface contact with the outer surface of the tube 11 with the flap closed 14 , To save material, a centerpiece 34 the flap 14 that the first inner surface 18 has, one out of the pipe 11 be separated piece so that it is reused. The middle piece 34 can z. B. welded out, sawn, milled or cut. The middle piece 34 can also with an outer, larger flap part 53 which is the pipe 11 overlapped, be connected so that both parts ( 34 . 53 ) the flap 14 form.

To the middle piece 34 around can be a circumferential seal 29 at the flap 14 and / or on the pipe 11 be arranged. The seal 29 also has the task of quasi replacing the missing by the separation process of the middle piece material at least partially and / or to close the tube airtight. The seal 29 may be made of rubber and / or with other seals z. B. the seal 58 can be combined, with sealing lips, a labyrinth seal and / or an O-ring seal can be used.

The wave 22 is under spring action, like 6d shows. Alternatively, a lever element 21 or another part under spring action. The feather 50 is a tension spring that is at one end with the shaft 22 , in particular a arranged on the shaft circumference, the first attachment approach, z. Evil 51 , is fixed and at the other end with the flap 14 near its fulcrum (see P1 in 2 ) via a second attachment lug 52 is attached. By the spring 50 acts a force that serves the locking claws 21a . 21b to keep in the open state. Dis is necessary to enable locking.

In 6e and 6f the eccentric function becomes clear, which serves to compensate for manufacturing tolerances and wear during operation. The pin 26 lies in the pin opening 54 , but a larger diameter than the pin 26 has, like 6e shows. This in 6f shown end of the pin carries the eccentric element 27 , which is a disc with a variety of marginal recesses 55 is. At a recess sits a fastener, z. B. a screw 56 , so that the disc is slightly pivotable about the screw and so the pin 26 can easily move what the locking function and the gripping of the lever element, such as 6g shows improved.

In addition, the outlet part has 10 a compressed air connection 57 , as in 6c can be seen, so that in the funnel area a so-called bridge formation is avoidable. The compressed air connection 57 is with the compressed air device 44 connectable.

The invention is not limited to this example, so instead of that welded joints are used, parts may also be made in one piece, for example, as castings or otherwise connected to each other, for. B. screwed, glued, riveted, etc. Other locking solutions or valve designs are possible. The device can also be used in other vehicles or silos. The outlet part is described here as funnel-shaped. Under "funnel-shaped" are other equivalent forms to understand, such. B. a hemisphere shape. Described and / or shown features can be combined with each other.
