Definitions
- the invention relates to a device for heat treatment, in particular for drying leather and the like, with a treatment chamber and a heating device which has a plurality of magnetrons (MG) provided with at least one circulating liquid cooling device (KV).
- MG magnetrons
- KV circulating liquid cooling device
- a device of this type is known from FR-A-2 076 405.
- the main object of the invention relates to this, namely the design of such a device in such a way that high availability and easy maintenance or repair of the heating device is ensured.
- the heating device has at least one magnetron fastened in a recess in the container wall with a cooling device that is connected to the container wall, and that at least one structural unit comprising the components of the magnetron that have a limited lifespan is separate from the cooling device is designed to be interchangeable.
- the object of the invention also extends to designing a device of the present type with liquid circulation cooling in such a way that the overall energy efficiency is improved.
- the solution to this problem is characterized in that the heating device has at least one magnetron with a cooling device which is connected to a Coolant circulation system is connected, which has heat exchange means for the transfer of the waste heat of the magnetron to a heating device.
- the task of the invention extends to designing a treatment device of the present type in such a way that a high degree of utilization can be achieved with short downtimes for loading and unloading the treatment chamber.
- the solution to this problem is based on a device for heat treatment, in particular for drying leather and the like, with a treatment chamber and at least one loading carriage that can be moved into and out of the treatment chamber, each carrying a load of the material to be treated.
- the solution is characterized in that the treatment chamber has two doors arranged in diametrical walls and a movement path for pushing the loading trolley through. This means that extending a treated batch and entering a new batch can be carried out practically simultaneously.
- FIG. 1 and 2 show a device for drying leather and the like.
- a treatment chamber TR in the wall W of which a heating device is provided with a plurality of magnetrons MG fastened in recesses in the container wall W, each with a cooling device KV.
- the latter is connected to the container wall W.
- the component WEB comprising components of the magnetron that have a limited lifespan is designed to be exchangeable separately from the cooling device KV.
- the exchangeable structural unit WEB comprises the vibration-active part SMG and the radiation part AS of the magnetron.
- the cooling device comprises an annular cooling space KL, to which a cooling water inlet KZ and a cooling water outlet KA are connected.
- Circulating agents which are customary per se, not shown, ensure the coolant exchange.
- this circulation system contains at least one heat exchanger, which is also conventional per se, for transferring the waste heat of the magnetron to a heating device.
- a loading trolley BW is provided which can be moved into and out of the treatment chamber and carries a load of the material to be treated.
- the treatment chamber has two doors STE, STA arranged in diametric walls and a movement path BB for pushing through the loading trolley BW.
- One of the doors, namely STE, is provided for retracting and the other door STA for extending the loading trolley.
- This is equipped with a multi-axle RS double wheel set for the constant passage of the door sill areas with their practically unavoidable joints F. In this way, the loading trolley can be moved quickly and without interference between the outer roller tracks RB and the movement path BB arranged in the treatment chamber TR.
- the loading trolley BW is designed as a flat frame FR and is inserted on rails SCH into the upper part of the treatment chamber TR.
- a movable frame FG is arranged in front of the treatment chamber TR for this flat frame FR.
- the flat frame FR can also be received in front of the treatment chamber TR by means of a fixed rail system FSCH.
- Fig. 5 - on the flat frame FR rods made of microwave-permeable plastic STM and clips for leather made of microwave-permeable plastic KLM are arranged.
- the parts made of steel, which could cause a disturbance of the electromagnetic field in the treatment chamber TR, are thus reduced to a minimum.
