Description

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

[0002] Devices for conveying viscous materials, especially drum pumps, are used in numerous industrial applications, such as the industrial storage of viscous materials. These devices serve, for example, to convey or transfer viscous materials from a storage location to an application or processing location. They are often used where the viscous material is used or further processed. It is not uncommon for other processing equipment to be fully or at least partially powered by compressed air. In current processing facilities, compressed air is supplied separately from the processing equipment, leading to increased costs for its provision. Summary of the invention

[0003] It is an object of the present invention to provide devices for conveying a viscous material from a container which are capable of providing compressed air in addition to the pumping power.

[0004] 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.

[0005] According to one aspect of the invention, a device for conveying a viscous material from a container with a compressed air generation system is described. The device comprises a pump suitable for conveying the viscous material from the container, wherein the pump has an electromechanical spindle drive with a spindle configured to perform a translational movement, and a compressed air generation device for generating compressed air, wherein the compressed air generation device comprises an air supply line, a piston, a cylinder, a compressed air outlet, and a compressed air tank, wherein the compressed air generation device is arranged on or at the pump such that the spindle and the piston are directly coupled to each other, wherein the piston is movably arranged within the cylinder, and wherein the air supply line is coupled to the cylinder and configured to introduce air into the cylinder.wherein the compressed air outlet couples the cylinder to the compressed air tank and is configured to direct compressed air from the cylinder to the compressed air tank, and wherein the air supply line has a check valve.

[0006] The term "viscous material" here refers to any fluid in a liquid or gaseous state. Viscous materials, such as adhesives, have a very high viscosity, requiring the subsequent plate to exert considerable force to be pressed downwards into the container.

[0007] The term "container" represents any device in which the viscous material can be arranged. For example, the container is a bucket, a barrel, a tub, or a tank, but is not limited to these. The container can 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, can 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 can be made of the same or a different material as the conveying tube.

[0008] The term "pump device" represents any device suitable for pumping or conveying a viscous material from a container. For example, the pump device can be a drum pump, but is not limited to this. The pump device may have an electromechanical spindle drive. The electromechanical spindle drive has a spindle that performs, or is configured to perform, a translational movement, i.e., raising and lowering the spindle. A compressed air generating device may be arranged on the pump device, particularly on a side opposite the drum pump tube, but is not limited to this. The spindle drive may include, but is not limited to, a motor and a gearbox.

[0009] The term "compressed air generating device" represents any device suitable or configured for generating compressed air. The compressed air generating device may include, but is not limited to, an air supply line, a piston, a cylinder, a compressed air outlet, and a compressed air tank. The compressed air generating device is arranged on or attached to the pumping device in such a way that the spindle and the piston are directly or indirectly coupled to each other. Through the coupling or connection of the spindle to the piston, the translational movement of the spindle is transmitted to the piston. The piston may be movably arranged within the cylinder, so that when the spindle moves, the piston moves within the cylinder or the interior of the cylinder. In other words, the piston and the cylinder form a chamber within the cylinder.The air supply line is connected to the cylinder, specifically to the chamber inside the cylinder. The air supply line can be configured to introduce air into the cylinder or the chamber. The compressed air outlet can be configured to connect the cylinder to the compressed air tank, or it can be configured to direct the compressed air from the cylinder to the compressed air tank. The compressed air tank is any device configured and suitable for storing compressed air at a pressure of 20 to 30 bar.

[0010] According to one embodiment of the invention, the compressed air discharge has a check valve.

[0011] By providing a check valve in the compressed air line, a loss of air pressure can be reliably prevented.

[0012] According to another embodiment, an air filter is arranged within the air supply line, or the air supply line is coupled to an air filter with the cylinder.

[0013] By providing an air filter, the air can be filtered before it enters the cylinder via the air supply line. This reliably prevents contamination of the air supply line and the cylinder, as well as the cylinder's interior, the compressed air outlet, and / or the compressed air tank. This ensures long-lasting functionality and low maintenance requirements for the device.

[0014] According to another embodiment, the compressed air tank has a compressed air outlet.

[0015] By providing a pressure outlet or connection, the compressed air contained in the compressed air tank can be supplied to at least one compressed air consumer (e.g., valves). Thus, compressed air can be used to power at least one other device. Brief description of the characters

[0016] Embodiments of the present disclosure are described in detail below with reference to a figure. Fig. Figure 1 shows a device for conveying a viscous material from a container using compressed air generation. Detailed description

[0017] Fig.Figure 1 shows a device for conveying a viscous material from a container using compressed air generation. The device 100 includes a pump 10. The pump 10 has an electromechanical spindle drive 11 with a spindle 12, the spindle drive 11 driving the spindle 12 such that it performs a translational movement, i.e., a lifting and lowering motion. The device 100 further includes a compressed air generation device 20. The compressed air generation device 20 is arranged on the pump 10. The compressed air generation device 20 has an air supply line 21, a piston 22, a cylinder 23, a compressed air outlet 24, and a compressed air tank 25. The spindle 12 of the pump 10 and the piston 22 of the compressed air generation device 20 are directly coupled to each other, so that a translational movement of the spindle 12 causes the piston 22 to perform a translational movement.The piston 22 is movably mounted within the cylinder 23. The air supply line 21 is connected to the cylinder 23 and supplies air to the cylinder 23. The compressed air outlet 24 connects the cylinder 23 to the compressed air tank 25. The air supply line 21 includes a check valve 27. In other words, when the piston 22 moves downwards within the cylinder 23, air is drawn into the cylinder 23 through the air supply line 21. When the spindle 11 moves upwards, the piston 22 also moves upwards, so that the air drawn in through the air supply line 21 is forced out of the cylinder 23 through the compressed air outlet 24 into the compressed air tank 25. The check valve 27 prevents air from escaping through the air supply line.

[0018] Optionally, the compressed air line 24 includes a check valve 26. The check valve 26 is located between the cylinder 23 and the compressed air tank 25. The check valve 26 prevents compressed air from flowing back from the compressed air tank into the cylinder 23.

[0019] Optionally, the check valve 27 is arranged between the cylinder 23 and the air filter 28. The check valve 27 prevents compressed air from escaping from the cylinder through the air filter.

[0020] Optionally, the air supply line 21 has an air filter 28, wherein the air filter 28 is arranged inside the air supply line 21 or the air supply line 21 couples the air filter 28 with the cylinder 23.

[0021] Optionally, the compressed air tank 25 has a compressed air outlet 29.
