Abstract

The silo (1) has a container (2) supported on a supporting structure, where an upper part of the container has a circular cross section. Filling aids are provided for filling the container with bulk goods to be stored. Delivery aids (4) e.g. linear actuator, deliver the bulk goods from the container to a transport vehicle (100). An outlet device (5) is in form of a connecting element (6) and has a cross section between a lower part of an unloading body and an outlet unit (7), where the cross section increases towards a base. The delivery aids open and close the outlet unit. An independent claim is also included for a system for controlling the delivery of bulk goods from a silo.

Description

  • The present invention relates to a silo for storage and metered unloading with different throughputs and exclusively by gravity of bulk material, in particular salt to prevent ice formation on roads, without forced movement of the bulk material.
  • Today silos with a circular container cross section (ie cylindrical silos) are often used, the container being stored on a frame so that it is so far above the ground that the transport vehicles (trucks with a corresponding structure) can enter under the container and the Bulk material in the container can be filled via a special outlet unit in the structure of the truck.
  • Typically, between the upper part of these silos (which, as mentioned above, have a basically cylindrical cross-section) and the outlet unit is a lower connecting element with a basically frusto-conical course
  • One of the biggest drawbacks of this type of silo is that the unloading of the bulk material, as already mentioned, takes place through a circular (usually small) outlet unit, which leads to the concentration of the discharged bulk material at a single point of the truck. In order to distribute the bulk material over the entire length of the truck body, the truck must therefore be moved under the silo during the loading process
  • Another disadvantage of the silos described above is that not infrequently bridges of compacted bulk material arise during the unloading process, in particular at high discharge speeds, which lead to the formation of cavities. Falling bulk material may then generate in such cases inside the container such negative pressures that the tightness of the structure is endangered as such.
  • Increasingly, the storage areas on which such silos are placed, also from various transport vehicles, the different, with to the use of bodies or administrations in case of need, are approached (removal of the bulk material in the self-service procedure). In particular, in self-service systems, it proves to be particularly important that the removal processes run quickly and flexibly, ie. that they can be adapted to different transport vehicles approaching the silo.
  • From the Scriptures EP 950 622 B1 a silo according to the preamble of claim 1 is known.
  • From the German utility model DE 83 26 788 U1 is a silo known for granules or similar media The silo consists of a vertically oriented cylindrical container, which merges on the bottom side in a downwardly frusto-conical muzzle end The muzzle end continues into a discharge nozzle, which has several outlet openings with pipe sockets for dispensing the medium Wedge-like tapering of the basically cylindrical outlet nozzle results from side walls so that a bottom remains as a narrow rectangular surface.
  • The problem with this spout is that it is continuously tapered and thus increasingly exerts restraining forces on the granules. In order to maintain the flow of granules nevertheless, complicated installations such as traffic cones and channels are required. A sub-task of the invention is to avoid such internals and still allow an undisturbed run of the granules
  • From a further prior art according to the German patent DE 1116 157 C is a conically extended barrel space known to join the chutes down. The outlets of the chutes each have a rectangular cross-section, whereby the four corners of the spout are not covered by the drip space. The cross-section of the chutes clearly decreases in comparison to the lower cross-section of the drip space
  • The main object of the present invention is to provide a silo for storage and unloading of bulk material, which overcomes the disadvantages described above or as far as possible reduced Within the scope of this task, an object of the present invention is in particular a silo for storage and unloading of bulk material to be able to discharge the bulk material quickly, so as to enable an immediate distribution of the salt on the road
  • Another object of this invention is to provide a silo which allows for efficient and even unloading of the bulk material onto the means of transport, whereby the bulk material is distributed over the entire surface of the means of transport without having to move the truck during the loading process. Not least object of this invention is to present a silo for storage and unloading of bulk material, which is able to optimize the unloading of bulk material on vehicles of different sizes and dimensions and in particular to prevent compression of the bulk material in the region of the outlet unit
  • This object and these and other advantages, which are discussed in more detail below, are achieved by a silo for storage and metered unloading by gravity of bulk material, in particular salt to prevent the formation of ice on roads, on a means of transport, consisting of one on one Supporting structure mounted container whose upper part has a basically circular cross-section, while the underlying Entladekorpus has the shape of a truncated cone with downwardly decreasing cross-section, and consisting of filling for filling the container with the bulk material to be stored and discharge aids for discharging the on the vehicles to be filled bulk material. The silo is characterized by an outlet device in the form of a connecting element with increasing cross-section towards the bottom between the lower part of the discharge body and an elongate outlet unit, the opening and closing of the outlet unit being effected by the discharge aids.
  • Further characteristics and advantages of the invention will become apparent from the description of some preferred but not exclusive embodiments of a silo for storage and metered discharge by means of gravity of bulk material according to the invention, illustrated by way of example and not limitation in the accompanying drawings, in which:

  • In the embodiments presented below, individual properties associated with particular examples in the actual embodiment may be replaced by other properties contained in other embodiments. The above-mentioned figures show a preferred embodiment of the silo designated in its entirety as number 1 for the storage and metered discharge by means of gravity of bulk material, in particular of salt to avoid ice formation on roads, on a transport vehicle 100.
  • With particular reference to the illustrated embodiments, the silo 1 consists of a container 2, which typically supports on a frame 3
  • The container 2 consists of an upper container part 2a with a basically circular cross-section (so that practically a cylindrical body is formed) as well as a fundamentally frusto-conical take-off body 2b arranged therebelow with a downwardly decreasing cross-section. The silo also has filling aids of known type for filling the container According to the invention, the silo 1 includes an outlet device 5, consisting of a connecting element 6, which is located between the lower part 2c of the bottom arranged removal body 2b and the elongated outlet unit. 7 Seen in detail, the elongated outlet unit 7 may have in its longitudinal course 101 a plurality of outlet openings 8, which may change between a closing and at least one opening state: As will be explained in more detail below, is t the state of the individual outlet openings 8 independently of the state of the remaining outlet openings 8 variable according to a preferred embodiment, which inter alia from the overview drawing in Figure 4 is apparent, the connecting element 6 is designed so that the outlet unit 7 is longer than the diameter of the lower part 2c, while their cross section should preferably be smaller than this diameter
  • The change between the closed state and the various opening states is first effected by operating the discharge aids 4. More specifically, and with reference to FIG Figure 4 , The discharge aids 4 may consist of perforated plates 31 and 32, whose movement is controlled so that at least a first and a second opening state of the outlet unit 7 can be generated. The two plates 31 and 32 are connected to an actuating element 33 and together with this form a discharge unit
  • Conveniently, the perforated plates 31 and 32 are provided with holes 34 and arranged one above the other. One of the two plates (designated as number 31) is fixed while the other plate 32 of the discharge unit is movable and moved by means of the actuating element 33
  • The fixed plate 31 is fixedly mounted in and closes the outlet unit 7, while the movable plate 32 is supported so as to be slidable in parallel with the fixed plate.
  • In this way, the movable plate 32, by the actuation of the actuator 33, assume a starting position in which the holes 34 of the two plates 31 and 32 are not superimposed and a plurality of intermediate positions in which the holes 34 of the two plates 31 and 32 are partially superimposed and an end position in which the holes 34 of the two plates 31 and 32 completely overlie each other, so that the removal rate of the bulk material can be varied depending on the amount of bulk material to be unloaded and optionally on the properties of the means of transport
  • When the plates 31 and 32 are in the intermediate positions and in the end position, respectively, they practically form the passage openings 8 which allow the bulk material to be concentrated not concentrated at one point but along the whole (or, as will be explained below). partial) length of the outlet unit 7.
  • In the starting position, the holes 34 of the two plates 31 and 32 form no passage for the bulk material and the outlet unit 7 is sealed. In the end position, the holes 34 of the two plates 31 and 32 lie on each other and form the largest possible passage opening for the bulk material, the outlet device 7 has the largest removal capacity in this position
  • In the intermediate positions passage openings are formed with intermediate diameters, by means of which the removal of the bulk material can be metered through the outlet unit 7 and in particular through the outlet openings 8
  • The choice of the respective position depends on the amount of bulk material to be unloaded, on the grain size of the bulk material to be unloaded and on the time available for filling and can be varied as a function of the desired discharge speed
  • Conveniently, the actuator 33 is equipped with a linear actuator, which may advantageously consist of a hydraulically driven piston on the Container 2 is attached The free end of the piston is connected to the movable plate 32 to move this movable plate 32, by extension and retraction in the starting position, the intermediate positions and the end position
  • In Figure 4 is schematically (number 21) a safety device, preferably a pressure accumulator, shown such safety devices are known and their purpose is, in case of power failure or emergency, release the pressure stored in them and deliver to the piston 33 to the movable plate 32 immediately in to bring the starting position.
  • Another, particularly important aspect of the present invention is that each outlet opening 8 is associated with a striking plate 10, which can be moved between a closed position of the respective outlet opening 8 and at least one opening position in which it does not close the passage opening of the outlet opening 8. The function of the strike plates 10 is - even if the overlapping of the holes 34, the different passage openings are formed, i. in the case of escaping or ready-to-take bulk material - act locally on the outlet openings 8 and adapt the passage cross-section of the outlet unit 7 to the size of the transport vehicles 100. The striker plates 10 may be actuated automatically by the discharge aids (eg, by the linear actuators 33a), but may also be moved by hand
  • In this connection, the option of automatically actuating the striking plates 10 proves to be particularly advantageous in the case of self-service silos 1 and, in general, when the withdrawals are frequently made with means of transport of different sizes and different capacities. In this case, after the type of transport vehicle 100 which requested the removal of the bulk material has been recognized and identified by means of basically known technologies, the discharge aids (in particular the linear actuators 33a) bring the strike plates 10 into the closed or open position to the Extraction cross-section automatically adapted to the dimensions of the transport vehicles As shown schematically in the overview drawing 4, the strike plates 10 can be connected to the linear actuators 33a, which are able to allow the movement of the strike plates
  • The operation of the silo according to the invention for storage and metered unloading by gravity of bulk material, especially salt to prevent ice formation on roads, on a transport vehicle, is clear from the foregoing, it has been shown that the use of an elongated outlet unit in addition to an increase the discharge speed (and thus faster distribution of salt on the roads) also enables a better distribution of the bulk material in the structure of the transport vehicle
  • Furthermore, it was shown that the silo described above allows a discharge of the bulk material only by gravity, d h. without the use of mechanical aids in the form of carriages, racks or the like, whereby a significant cost savings both in terms of construction costs and in terms of the cost of the completion of the removal operations is achieved and the leakage of the bulk material is guaranteed even under the most difficult conditions
  • The invention thus conceived may be subject to numerous changes or variations, all of which are within the scope of the inventive concept. For example, the silo 1 can be equipped with devices for detecting the correct position of the means of transport 100, which check whether the vehicle body is positioned so that the bulk material flowing out of the elongated outlet unit 7 passes completely into the vehicle body, whereby the risk of overflowing and of material loss is excluded
  • In the actual design, the dimensions can be adapted to any requirements. In addition, all details can be exchanged with other, technically equivalent elements
  • The present invention also relates to a system for controlling the discharge of bulk material from the silo. The known system for controlling the delivery of bulk material from a silo provides that the user drives his truck to the silo place and turns off his vehicle there so that the Truck body is below the bulk material outlet. The user then exits the cab and moves to a pillar where the interface to transfer the data to the control system is located; this column is usually provided with an operator keyboard and a screen, so that the user can enter his identification code and, after being recognized by the system, can request the delivery of the desired bulk quantity. After loading the truck with the bulk material, the user climbs back into the driver's cab and leaves the silo place. In other control systems, the recognition of the user is not done by entering a code number on a keyboard attached to the column, but by means of a non-contact recognition device (eg chip card), which is also mounted on a column.
  • It is obvious that the main disadvantage of the systems briefly described above is that the user (truck driver) has to get out of the cab and go to the pillar to connect to the control system's control instruments. This is especially true problematic because these silos usually contain salt to prevent the formation of ice on the roads and the delivery therefore takes place under relatively unfavorable weather conditions Another disadvantage is the long duration of these operations, which has a negative impact on the speed of use on the roads In the trial To overcome the disadvantages described above, columns have been proposed in which the input keyboard is connected via a connecting cable to the column so that the user sit in the truck and by bending out of the window, the keyboard, which usually with connected to a display device , to get into the driver's cab.
  • After the recognition process and the choice of the amount of charge, the driver, by bending out of the window again, put the keyboard with the display device back to the column Although this solution solves some of the disadvantages complained of in conventional control devices, it is still not free of disadvantages
  • On the one hand, this device also requires an inconvenient method of recognizing the user. On the other hand, access to the keyboard is not always convenient due to the different dimensions of the trucks that can approach the silo terminal. The additional object of the present invention is a system to provide for the control of the delivery of bulk material from the silo, which is able to remedy these drawbacks or reduce as much as possible
  • In the context of this task, a purpose of this invention is, in particular, to provide a system for controlling the discharge of bulk material from the silo, which makes it possible to simplify and, above all, to speed up the recognition of the user (especially in systems with possible self-service) and the Selecting the amount of bulk material to be delivered to the user more pleasant
  • These objectives are achieved by a system for controlling the discharge of bulk material from a silo, with controls to control the discharge of bulk material from the silo. The aforesaid system is characterized by the fact that it includes wireless remote data transmission devices owned by the user and able to remotely connect with the above mentioned control instruments to these control instruments To provide information about the user's identification code and the bulk quantities requested by the user.
  • Advantageously, the system according to the invention provides that the devices for remote data transmission include a recording body with keyboard, which is in the possession of the user and is able to send data wirelessly to the control instruments, which in turn with at least one visible to the user display device for information about the operations in progress. Further characteristics and advantages will become apparent from the description of some preferred but not exclusive embodiments of the system for controlling the discharge of bulk material from the silo, which are given by way of example and not limitation in FIG Figure 5 In the embodiments presented below, individual properties associated with particular examples in the actual embodiment may be replaced by other properties contained in other embodiments
  • With reference to the Figure 5 For example, a system for controlling the discharge of bulk material from a silo 102, collectively referred to as number 101, comprises control instruments 103, typically located in a control panel 104 located in the vicinity of the silo 102 and thus the discharge area, and to control the discharge of bulk material from the silo 102 into the superstructure 105a of the truck 105
  • According to the invention, the control system 101 includes wireless remote data transmission devices 6 owned by a user 107 and capable of establishing a remote connection with the control instruments 103 for providing to these control instruments 103 information regarding the identification code of the user 107 and the user 107 requested quantity of bulk material.
  • The remote data transmission devices 106 first include a receiving body 106a having a keyboard 106b in the user's possession and being capable of data wirelessly when the user 107 operates the keys, and typically with the aid of a radio wave transmitting / receiving system to send the control instruments 103. In the case described above, the control instruments 103 are connected to at least one, for the user 107 visible display device 108 for information on the operations in progress This display device can be arranged so that it is visible from the cab of the truck 105, if this with his Structure is positioned correctly below the bulk material outlet openings of the silo 102.
  • The control system 101 should desirably be equipped with trucks 105 correct position detection devices which check that the truck 105 is positioned so that the body 105a is below the outlet 102a of the silo 102
  • According to an embodiment not shown in the figure, the remote data transmission devices 106 can of course also be in a data input device with display, which is in the possession of the user 107 and capable of wireless data (eg via radio) to the control instruments 103 In accordance with a particularly important aspect of this invention, the control instruments 103 are capable of generating a pseudorandom test routine that can be displayed on the display device 108 and includes numerous feedback responses that are queried at the user 107 to enable the unloading process; these control instruments are also typically equipped with a receiver capable of verifying the feedback provided by the user 107 via the keyboard 106. The pseudorandom routine generated by the control instruments 103 advantageously provides that the user 107 all for the execution of the A further aspect provides that the remote data transmission devices are able, simultaneously with the transmission of the individual data to the processes being executed, data for the identification code of the User 107 to the control instruments 103 to send. This allows the control instruments to exclusively release the receipt of data from the user who initiated the control system 101
  • In this context, it has proved to be extremely advantageous to design the aforementioned control instruments 103 so that they are able to change from an inoperative to an operational state as soon as they - at the moment in which the user 107 his vehicle positioned in the vicinity of the silo 102 and has pressed any key on the keyboard 106 - which has received recognition data from the remote data transmission instruments 106. The control system immediately checks, based on an analysis of the data stored in the control instruments 103, whether the obtained recognition code for discharging bulk material entitled to the silo 102 If authorized, the control instruments, as already mentioned, change to the ready state and establish a connection with the remote data transmission instruments 106 to generate / verify the pseudorandom routine and thus data regarding the amount of S to be delivered schüttguts to send. In order to further ensure that the pseudo-random routine checks as well as the transmission of data concerning the bulk material to be dispensed are concerned, it is contemplated that the control instruments 103 will be able to perform on all to check whether the data associated with the aforementioned pending command matches the detection data which caused the last change of the control instruments 103 from the non-operational to the operative state.
  • Conveniently, the control instruments 103 are capable of switching from the operative to the inoperative state if they do not receive data from the remote data transmission devices 106 within a preset period of time
  • In the actual design, the dimensions can be adapted to any requirements. In addition, all details can be replaced by other, technically equivalent elements
