Description

[0001] The present invention relates to a device for conveying a viscous material from a container. Technical background

[0002] Devices for conveying viscous materials, in particular devices for conveying viscous materials from a container, are used in numerous industrial applications, for example in the industrial storage of viscous materials. Devices for conveying viscous materials serve, for example, to convey or transfer viscous materials from a storage location to an application or processing location.

[0003] A typical device for conveying a viscous material typically includes a high-pressure pump, in particular a scoop pump, which has a high pneumatic drive power.

[0004] Known devices for conveying a viscous material are very maintenance-intensive and prone to malfunctions due to the use of high-pressure pumps and complicated and multi-part pump designs, so that the service life of this known device is quite short and the maintenance intervals are short. Summary of the invention

[0005] It is an object of the present invention to provide devices for conveying a viscous material from a container, which have a simplified design and thus reduced maintenance requirements and susceptibility to malfunctions. This allows the service life of the devices for conveying a viscous material to be significantly increased and the maintenance intervals to be significantly reduced.

[0006] At least one of the problems, or further problems, that arise for a person skilled in the art from the present disclosure are solved by the subject matter of the independent claim. Advantageous embodiments are the subject matter of the dependent claims and the description.

[0007] According to one aspect of the invention, a device for conveying a viscous material from a container is described. The device comprises a container in which the viscous material is arranged; a conveying device for conveying the viscous material out of the container, which extends into the container, in particular into the viscous material in the container, and which is axially rotatable; and a low-pressure pump, wherein the low-pressure pump is coupled to the conveying device, wherein the conveying device comprises: a conveying tube; and at least one scraper for moving the viscous material, wherein the at least one scraper is attached to the conveying tube.

[0008] The term "viscous material" here represents any fluids in a liquid or gaseous state.

[0009] The term "container" represents any device in which the viscous material can be arranged, stored, or contained. For example, the container could be a bucket, a barrel, a tub, or a tank, but this is not limited to these. The container may have at least one side wall, a bottom plate, and an opening opposite the bottom plate, with the at least one side wall extending perpendicularly from the bottom plate. The container, and in particular the at least one side wall of the container, may have an outer diameter and an inner diameter, such that the container has a "hollow" internal volume in which the viscous material can be arranged. The container may be made of the same or a different material as the conveying device.

[0010] The term "conveyor" refers to any device configured to convey viscous material from the container, i.e., from within the container's internal volume. The conveying device extends into, or is inserted into, the container, specifically into the viscous material within the container. The conveying device is axially rotatable. It may be coupled to a rotary motor. The conveying device comprises a conveying tube and at least one scraper.

[0011] The term "conveyor tube" refers to any device that has a hollow cylindrical shape and is designed and configured to convey a viscous material from a container. The conveying tube may be made of metal or plastic, but is not limited to this material. The conveying tube has an outer diameter and an inner diameter, the inner diameter being smaller than the outer diameter. The conveying tube may be inserted into the container through the container's opening. Alternatively, the conveying tube may extend through at least one side wall or bottom plate of the container. The conveying tube may have an inlet opening and an outlet opening. The outlet opening may be connected to, and in particular directly connected to, the low-pressure pump. The inlet opening of the conveying tube may be connected exclusively to, and in particular directly connected to, the outlet opening of the at least one scraper.The conveying tube can extend vertically into the container. The conveying tube can extend perpendicularly to at least one scraper, but is not limited to this.

[0012] The term "scraper" represents any element or device configured to move the viscous material within the container. The scraper may be located directly at an inlet opening, in which case the scraper is a solid body. Alternatively, the scraper may, but is not limited to, a hollow cylinder. If the scraper is a hollow cylinder, it may have an inlet opening and an outlet opening, the outlet opening being coupled exclusively to, and in particular directly to, the inlet opening of the conveying tube. The scraper may, but is not limited to, be made of the same material as the conveying tube. The scraper may extend perpendicular to the conveying tube. The scraper may, but is not limited to, have the shape of a propeller blade. The scraper may have a plurality, i.e.,at least two inlet openings, wherein the inlet opening is arranged on the side of the scraper in the direction of rotation.

[0013] According to one embodiment of the invention, the at least one scraper is hollow, wherein the at least one scraper has an inlet opening and an outlet opening, wherein only the outlet opening of the at least one scraper is arranged at an inlet opening of the conveying tube.

[0014] The term "hollow" here represents the fact that the scraper can have the shape of a hollow cylinder, but is not limited to this.

[0015] According to another embodiment, the container is arranged on a lifting device.

[0016] The term "lifting device" represents any device configured to lift or raise a container and hold it in the raised position. For example, a lifting device could be a crane or a scissor lift, but this is not the only option.

[0017] By using a lifting device, the depth of extension or penetration depth of the conveying device into the container can be easily adjusted.

[0018] According to a further embodiment of the invention, the at least one scraper has at least two inlet openings.

[0019] By providing multiple inlet openings in at least one scraper, the number of conveying positions—that is, the positions at which the viscous material can enter the conveying device—can be increased. This ensures a uniform conveying of the viscous material.

[0020] According to another embodiment of the invention, the low-pressure pump is directly coupled to the conveying tube.

[0021] According to a further embodiment of the invention, the conveying device is coupled to a rotary motor.

[0022] The term "rotary motor" refers to any motor configured to rotate the conveying device. The rotary motor can be directly coupled to the conveying device, particularly to the conveying pipe, via a gearbox, chain, or belt.

[0023] According to a further embodiment of the invention, the at least one scraper extends perpendicular to the conveying tube.

[0024] According to a further embodiment of the invention, the horizontal extent of the at least one scraper is smaller than the radius of the container.

[0025] By specifying that the horizontal extent of at least one scraper is smaller than the radius of the container, it can be ensured that the conveying device and thus also the at least one scraper can be placed in the container and rotate there.

[0026] According to another embodiment of the invention, the container is a barrel.

[0027] The term "barrel" here represents a container that has a cylindrical shape with a single side wall and a bottom plate. Brief description of the characters
