Definitions

  • the invention relates to a device for loading a rotary tubular furnace with pneumatic vehicle tires, consisting of a lock chamber which is provided on the side of a furnace inlet at the front opposite the furnace and carries two alternately openable closures arranged on the furnace and on the task side.
  • a disadvantage of this known device is, above all, that the pneumatic vehicle tires cannot be placed in a specific furnace area, so that the desired combustion conditions cannot be guaranteed without further notice. In addition, it is difficult to ensure an even supply of fuel via the lock chamber, because pneumatic vehicle tires of different sizes must be expected.
  • the invention is therefore based on the object to improve a device for loading a rotary kiln with pneumatic vehicle tires of the type described in such a way that a certain storage area for the tires introduced can be ensured in the oven and the rotary kiln is evenly supplied with fuel.
  • the invention solves the problem that the Lock chamber, as is known per se, forms a runway inclined towards the furnace inlet for pneumatic vehicle tires with a length corresponding to at least twice the tire diameter and that the feed-side closure on its side facing the lock chamber has a tire holder which holds the pneumatic vehicle tires in a roll position aligned with the runway, which consists of a clamping device with two clamping jaws which can be actuated in opposite directions and which can be adjusted against the side walls of the pneumatic vehicle tires and are adjustably mounted parallel to the runway and transversely to the direction of travel.
  • a runway with a length corresponding to at least twice the tire diameter in connection with the special tire holder in the area of the closure on the task side, enables sufficient acceleration for the tires at the end of the runway in order to allow the tires to travel far enough after leaving the runway To roll rotary kiln. If a tire is released by the tire holder, its acceleration cannot be hindered by the lock on the oven side of the lock chamber, because this lock was opened before the tire was released and does not itself form the tire holder.
  • the length of the acceleration path as well as its inclination and orientation with respect to the rotary kiln determine the entry range, so that this entry range can also be adjusted to the desired conditions using these quantities.
  • the tire holder consists of appropriately adjustable clamping jaws, the pneumatic vehicle tire inserted into the clamping device when the closure on the task side is open is aligned between the correspondingly actuated clamping jaws in relation to the runway in a rolling position, the tire being introduced into the lock chamber when the closure is closed that the tire holder in the closure area results in a very simple tire task.
  • the uniform fuel supply can be ensured despite the use of different tires if the tire holder is controlled by a time control depending on the tire weight. This means that larger time intervals can be maintained after the introduction of larger tires and smaller time intervals after the introduction of smaller tires until the entry of the following tire in each case.
  • the introduction of pneumatic vehicle tires depending on their weight is known, but the control over the loading intervals offers considerable advantages over the known control of the number of tires, because the loading of the rotary kiln with individual tires can run undisturbed.
  • the weight of the tire will generally be unknown, it must be determined for the even loading of the rotary kiln before or during the loading.
  • closure having the tire holder can be designed very differently, particularly simple constructional conditions result if the closure having the tire holder consists of a rocker arm which is pivotably pivoted to the lock chamber. Due to the possible pivoting of the rocker-like closure, the closure side facing the lock chamber is freely accessible, which ensures that the individual pneumatic vehicle tires are easily released.
  • the oven-side lock of the lock chamber which is designed as a swivel flap with a swivel axis in the area of the runway, forms part of the runway in the folded open position, the gas-tight closure of the oven inlet with respect to the lock chamber can simultaneously be achieved with a trouble-free transfer of the goods rolling on the runway into the oven area Tires are guaranteed because the sealing surfaces for the furnace-side closure do not form any defects in the runway.
  • the charging device for a rotary kiln 1 shown has a lock chamber 3 connected to the front end of the kiln inlet 2 and carrying a heat-resistant lining 4.
  • the Passage opening between the furnace inlet 2 and the lock chamber 3 is provided with a closure 5, which consists of a swivel flap 6, which can be folded down into its open position by means of a working cylinder 7 about a lower swivel axis 8, as is indicated by dash-dotted lines.
  • the feed-side closure 9 of the lock chamber 3 is formed by a rocker arm 11 which can be pivoted about a pivot axis 10 and which can be pivoted with the aid of a cable or chain hoist 12 between the open position drawn with solid lines and the closed position indicated by dash-dotted lines.
  • the feed-side closure 9 has a tire holder 13, which consists of a clamping device with two mutually adjustable clamping jaws 14, which can be pressed from both sides against the side walls of a pneumatic vehicle tire 15 supplied to the holder 13.
  • each of the tires 15 supplied to the bracket 13 is aligned with respect to the vertical longitudinal plane of the rocker 11 and thus the lock chamber 3 and held in the aligned position, so that the pneumatic vehicle tires 15 when the task-side, closure 9 are held in the lock chamber 3 in a rolling position.
  • the result is a runway 17 leading into the oven inlet 2 for the tires 15 held by the tire holder, via which the tires after opening the oven-side shutter 5 in can roll the rotary kiln 1.
  • the runway In order to be able to bring the tires 15 into the furnace 1 up to a certain area, the runway must have a length which ensures a sufficient speed of the tires when leaving the runway 17.
  • the runway 17 In practice, the runway 17 must have a length corresponding to at least twice the tire diameter, it being assumed that the tire is passing through Knife is referred to the largest of the tires suitable for the loading device in order to ensure that these tires also have a sufficient top speed when leaving the runway 17.
  • the furnace-side closure 5 of the lock chamber 3 is designed as a pivoting flap 6, this pivoting flap 6 can also be used as part of the runway 17 if this closure 5 is pivoted into the open position shown in broken lines with the aid of the working cylinder 7.
  • the tire holder 13 can be released by a corresponding action on the cylinders 16, the tire 15 released by the clamping jaws 14 rolling over the roller track 17 into the furnace inlet 2 and further into the rotary tube furnace 1.
  • the storage area of the tires entered in the rotary kiln 1 can be determined via the length of the runway 17, its inclination and the alignment of the runway with respect to the rotary kiln 1. The rotation of the furnace must of course be taken into account.
  • the combustion times for tires of different sizes must be taken into account.
  • the cylinders 16 of the tire holder 13 can be acted upon by a time control which controls the supply of the next tire depending on the tire weight of the tire previously inserted. If the closure 9 having the tire holder 13 is connected to a weighing device, which can be carried out simply by means of the cable or chain hoist 12 ', its weight can be determined for each tire 15 and the timing can be predetermined so that the loading intervals are dependent on the respective one Tire burn time can be selected. Feeding the pneumatic vehicle tires 15 to the feed side Closure 9 is to be caused because of the described timing of the loading within the combustion time of the previously inserted tire, which does not result in any difficulties. The operation of the loading device can thus be largely automated.
