Description

[0001] The invention relates to a heating chamber for heating a substance, in particular a solid, for the purpose of melting the solid, comprising a process chamber for arranging at least one container receiving the substance, wherein the heating chamber has a heating device, preferably electric, for heating the process chamber and / or the container and / or the substance.

[0002] A heating chamber of the type described above is known in practice and is regularly used to heat a solid for the purpose of melting it. Such a heating chamber typically comprises a process chamber for arranging at least one container to hold the solid and a heating device, preferably electric, for heating the process chamber. As a result of heating the process chamber by means of the heating device, the solid can then be heated at least until it reaches its melting temperature, at which point it melts. Furthermore, it is known in practice to attach an agitator to the container in order to support or accelerate the melting of the solid by the movement of the agitator during heating, in particular to save time and thus reduce the operating costs of the heating chamber.Attaching the agitator to the container before heating the solid and removing it afterward is time-consuming and involves additional operating costs for the heating chamber. Furthermore, the agitator, which is typically mounted on top of the container, is difficult to thermally insulate within the process chamber. Therefore, to prevent damage to the agitator from heat exposure, an upper temperature limit within the process chamber must not be exceeded. Consequently, the heating chamber is only suitable for melting solids with melting points below this upper limit, thus limiting its applicability. Additionally, if multiple containers holding the solid are arranged within the process chamber and the melting of the solid is supported in each container, further measures must be taken.To accelerate the heating process, each container must be equipped with its own agitator, which will further increase the operating costs of the heating chamber. Furthermore, some solids are so dense in the container when cold that the agitator cannot be forced into the solid before heating with reasonable effort, thus further limiting the usability of the heating chamber.

[0003] The present invention is therefore based on the objective of proposing a heating chamber for heating a substance, in particular a solid, for the purpose of melting the solid, which is cost-effective to operate and flexibly usable for heating a variety of substances, in particular solids, for the purpose of melting the solids.

[0004] This problem is solved by a heating chamber for heating a substance, in particular a solid, for the purpose of melting the solid, with the features of claim 1.

[0005] The heating chamber according to the invention for heating a substance, in particular a solid, for the purpose of melting the solid, has a process chamber for arranging at least one container receiving the substance, wherein the heating chamber has a heating device, preferably electric, for heating the process chamber and / or the container and / or the substance, wherein the heating chamber has at least one shaking device which is configured to shake the container, preferably during heating.

[0006] The heating chamber is used to heat a substance. The substance can be a solid, meaning a substance in a solid form. It can be a free-flowing solid, meaning a solid in a free-flowing, loose form, for example, in the form of granules, pellets, flakes, or scales. If the substance is a solid, it can be heated to melt it. The solid can be heated at least until it reaches its melting point. The substance can also be a liquid. It can be a pure substance or a mixture. The substance can also consist of both a solid and a liquid component.

[0007] The heating chamber includes a process space for accommodating at least one container holding the substance. The process space can be designed such that the container can be positioned upright within it. The container can be a drum or a pallet container, particularly an intermediate bulk container (IBC). The drum could, for example, be a 200-liter drum. The pallet container could, for example, be a 1000-liter container. The container could also be of another type. The process space can be sealed off from the surrounding environment and / or thermally insulated.

[0008] The heating chamber has a heating device, preferably electric, for heating the process chamber and / or the container and / or the substance. As a result of heating the process chamber and / or the container and / or the substance by means of the heating device, the substance can be heated. The heating device can be configured to heat air located in the process chamber and / or air that can be supplied to the process chamber. Thus, the process chamber can be heated by the fact that the air located in the process chamber and / or the air that can be supplied to the process chamber can be heated. By heating the process chamber, the container and thus the substance contained in the container can be heated. If the heating device is electric, it can comprise at least one, preferably at least two, and particularly preferably at least three, resistance heaters.It is also conceivable that the heating device is designed as a steam heater, a thermal oil heater, a gas heater, preferably equipped with a burner and / or at least one heat exchanger, and / or a tank heater, preferably equipped with a jacket heater and / or bottom heater.

[0009] The heating chamber, in particular the process chamber and / or the heating device, can be designed in such a way that a temperature of at least up to 200°C, preferably at least up to 300°C, particularly preferably at least up to 400°C, and most preferably at least up to 500°C, can be achieved in the process chamber.

[0010] The heating chamber has at least one vibrating device designed to vibrate the container, preferably during the heating process. This allows the container and its contents to be set into a vibrating motion by means of the vibrating device, thereby assisting or accelerating the heating of the substance, particularly the melting of solids, and thus saving time and consequently reducing the operating costs of the heating chamber. Furthermore, temperature-sensitive substances can be melted at comparatively lower temperatures by the vibration, thus preserving their quality. This is important, for example, for substances such as methylenediphenyl diisocyanate (MDI) or petrolatum.Since the vibrating device, unlike the previously known agitator, does not need to be attached to the container before heating the substance and removed afterward, heating the substance is comparatively less time-consuming, which in turn leads to comparatively lower operating costs for the heating chamber. Furthermore, it is generally possible to thermally shield the vibrating device by appropriately positioning it, particularly within the process chamber, so that the device is well protected from heat exposure even at relatively high temperatures in the process chamber. Therefore, with a suitable arrangement of the vibrating device, the heating chamber can also be used to heat solids with relatively high melting points for the purpose of melting them, resulting in flexible application of the heating chamber.Furthermore, the vibrating device makes it very easy to simultaneously vibrate multiple containers holding a substance, especially a solid. Moreover, unlike a known agitator, the vibrating device does not need to be inserted, or in particular pressed, into the substance, especially a solid. This makes the heating chamber suitable for heating substances, especially solids, that are solid in the container when cold, thus increasing the heating chamber's versatility. Overall, the heating chamber is therefore cost-effective to operate and can be used flexibly for heating a large number of substances, especially solids, to melt them.

[0011] The vibration device can be arranged within the process chamber. Specifically, it can be positioned in a section of the bottom wall of the heating chamber's housing. Alternatively, the vibration device can be located on the bottom wall and / or on a collection tray mounted on the bottom wall of the heating chamber to collect any material, particularly molten solids, that may escape from the container.

[0012] The heating chamber can have multiple vibration devices. This allows a larger quantity of the substance contained in several containers to be heated or vibrated simultaneously, or allows several containers holding the substance or different substances to be vibrated independently of one another, particularly with different vibration movements.

[0013] In a preferred embodiment, the vibrating device can comprise a vibrating plate that can be set into a, preferably periodic, vibrating motion, and the container can be arranged on the vibrating plate. The container can be arranged on the upper surface of the vibrating plate. The vibrating plate can be arranged on the base wall and / or the collection tray. The vibrating plate can be spring-mounted by means of at least one spring element of the vibrating device, in particular relative to the housing, especially the base wall, and / or the collection tray. The vibrating plate can be arranged at a distance from the base wall and / or the collection tray, in particular from the bottom of the collection tray. The spring element can form a spacer.

[0014] In a preferred embodiment, the vibrating device can include a drive unit, preferably electric, arranged below the vibrating plate, for setting the vibrating plate into motion. The drive unit can comprise at least one, preferably at least two, drive motors, preferably electric motors. If the drive unit is arranged below the vibrating plate, it can be easily thermally shielded from the process chamber located above the vibrating plate. The drive unit can be arranged between the vibrating plate and the bottom wall and / or between the vibrating plate and the collection tray, particularly the floor. The distance can be dimensioned such that the drive unit can be ventilated. This prevents heat build-up. Furthermore, the heat chamber can have thermal insulation for thermal shielding of the drive unit.Furthermore, the housing, in particular a first side wall of the housing and / or a second side wall of the housing, can have at least one ventilation slot. Preferably, the first side wall and the second side wall each have at least one, preferably two, ventilation slots. The drive unit can be ventilated via the ventilation slot(s).

The at least one pallet with the substance-receiving container arranged on the pallet, preferably designed as a drum, can be arranged on the vibrating plate.Preferably, the process chamber and optionally the vibrating plate can be designed to accommodate a pallet with up to four containers arranged on the pallet, preferably each designed as a barrel, each holding a substance, and / or two pallets with up to two containers arranged on the respective pallet, preferably each designed as a barrel, each holding a substance.

[0018] The heating device can be positioned above the vibrating device. This allows the vibrating device to be thermally decoupled from the heating device.

[0019] In a preferred embodiment, the heating chamber can include an air circulation device, preferably equipped with a fan, for circulating air within the process chamber. This allows the process chamber to be heated relatively quickly and evenly. The air circulation device can be designed as a recirculation unit. The air circulation device can then generate at least one recirculating airflow.

[0020] In a preferred embodiment, the air circulation device can be configured to generate an airflow such that air located in the process chamber can be discharged from the process chamber via an outlet opening of the heating chamber into an air guide area of ​​the heating chamber, subsequently guided past the heating device in the air guide area, and subsequently supplied from the air guide area into the process chamber via an inlet opening of the heating chamber. The heating device can be configured to heat the air passing past the heating device. The air guide area can comprise a horizontal air guide area and / or a vertical air guide area. The horizontal air guide area can be arranged between a ceiling wall of the housing and a first partition wall of the heating chamber spaced apart from the ceiling wall.The vertical airflow section can be arranged between the rear wall and a second partition wall of the heating chamber, spaced apart from the rear wall. The first partition wall can be separate from the second partition wall or integral with it. The housing can encompass the first and / or the second partition wall.

The door can also be a sliding door or another type of door. Furthermore, the door can have an air guide device, in particular an air baffle, on its inner side. The door can form a front wall of the housing.

[0025] In a preferred embodiment, the heating chamber can comprise a housing forming a process chamber, preferably with at least one vibration-damping mounting element for mounting the housing on a base.
