Description

Technical Field

[0001] The invention relates to the technical field of drum type vacuum plasma cleaning equipment, and in particular to drum type vacuum plasma cleaning equipment. Background Art

[0002] Plasma cleaning is the process of removing material from the surface of an object by using an ionized gas called plasma. The process is usually carried out in a vacuum chamber using a mixture of gases such as argon, oxygen, air and hydrogen / nitrogen. The low-pressure gas (usually about 1 / 1000 atmospheric pressure) is ionized by using a high-frequency voltage (usually kHz to MHz) to be broken down and ionized and generate plasma through glow power generation. The plasma generated in the vacuum chamber is allowed to completely cover the treated material and start cleaning; after cleaning, the high-frequency voltage is cut off and the gas and vaporized dirt are discharged, and air is blown into the vacuum chamber to raise the gas pressure to atmospheric pressure.

[0003] Existing vacuum plasma cleaning machines for cleaning powder or granular materials usually adopt a drum form. The powder or granular material is loaded into the drum of the cleaning machine, the cleaning machine is exhausted and vacuumed, the process gas is input, the high-frequency voltage is turned on to ionize the process gas, and the drum is driven to rotate at the same time. The powder or granular material rolls in the drum, and the powder or granular material exposed on the surface is bombarded by plasma and processed. After the cleaning is completed, the drum rotation is stopped, the interior of the cleaning machine is connected to the atmosphere, and the processed powder or granular material is taken out.

[0004] However, the powder material entering the drum, such as polyethylene, is an inert material with a certain degree of lipophilicity. Therefore, it will absorb moisture and other impurities in the air during storage and use. These impurities will form a layer of water and chemical mixture on the surface of polyethylene, thereby causing attraction between polyethylene particles, resulting in agglomeration. At the same time, polyethylene has a low density and is prone to static electricity during storage, which further promotes attraction and agglomeration between polyethylene. The plasma cleaning equipment in the prior art can only clean the surface of the powder, and cannot crush the agglomerated large particles. Therefore, a vacuum plasma cleaning machine is designed to crush the powder material entering the drum. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the present invention proposes a drum-type vacuum plasma cleaning equipment, including an outer sleeve and an inner drum arranged in the outer sleeve and rotatably connected to the outer sleeve, the outer sleeve is provided with an exhaust pipe connected to a vacuum pumping device and an electrode rod, the electrode rod passes through the outer sleeve and enters the inner drum, the electrode rod is provided with a gas flow groove for allowing process gas to enter the inner drum, the outer sleeve is provided with a driving component for driving the inner drum to rotate, and the inner cavity of the inner drum is provided with a breaking up component for breaking up compacted materials.

[0006] To achieve the above-mentioned purpose, when cleaning powdered or granular materials, the vacuum equipment provides power to evacuate the cleaning machine to the required vacuum degree, and the process gas is injected into the gas flow groove of the electrode rod. The process gas enters the inner drum through the gas flow groove, and the electrode rod is energized to generate plasma to clean the material to be cleaned. At the same time, the driving component provides power to drive the inner drum to rotate, thereby improving the cleaning efficiency of the powdered or granular materials. However, if the material is compacted during the cleaning process, the compacted material is broken up by the breaking up component to reduce the possibility of poor cleaning effect of the compacted material.

[0007] Furthermore, the breaking up assembly includes a plurality of inner stirring bars and outer stirring bars which are arranged at the bottom end of the inner cavity groove wall of the inner drum and are integrally formed with the inner drum, and the plurality of inner stirring bars and outer stirring bars are arranged in an array along the center line of the inner drum, and the circumferential outer wall of the electrode rod is also fixed with an extrusion bar which is located between the plurality of inner stirring bars and outer stirring bars and is close to the inner stirring bars and the outer stirring bars.

[0008] Through the above technical scheme, the compacted material falls between a number of inner stirring bars and outer stirring bars, and the inner roller moves to drive the compacted material to move into contact with the extrusion bars. When the extrusion bars pass through the inner stirring bars and the outer stirring bars, they will break up the compacted powdered material between the inner stirring bars and the outer stirring bars, thereby reducing the possibility of poor cleaning effect after the powdered material is compacted.

[0009] Furthermore, a control component is disposed outside the outer sleeve for controlling the outer sleeve to rotate so that powdered materials and compacted materials fall between the outer stirring bars and the inner stirring bars for easy dispersion.

[0013] Furthermore, the power assembly includes a power casing fixed on the frame, one end of the support bar passing through the frame passes through the power casing and is rotatably connected to the power casing, the part of the support bar passing through the power casing is coaxially nested with an A bevel gear fixedly connected to the support bar, a short shaft is rotatably connected to the inner groove wall of the power casing, a B bevel gear fixed to the short shaft is coaxially nested on the short shaft, the A bevel gear and the B bevel gear are meshed with each other, the end of the short shaft away from the B bevel gear passes through the power casing, and a handwheel is coaxially fixed to the part of the short shaft passing through the power casing.

[0014] Through the above technical solution, power is provided by manually rotating the handwheel to drive the short shaft to rotate, and power is transmitted through the short shaft, A bevel gear, and B bevel gear to drive the support bar to rotate, and then drive the outer sleeve to rotate.

[0015] Furthermore, a plurality of evenly arranged push bars are fixed to the inner cavity groove wall of the inner drum, and the push bars are arranged in an array with the center line of the inner drum as the center and correspond one-to-one to the outer extrusion bars. The push bars are located on the side of the stirring bars away from the extrusion bars, and the push bars are arranged obliquely, and each of the push bars is provided with a plurality of connecting holes for the passage of materials.

[0016] Through the above technical solution, by setting up a plurality of push bars, the material in the inner drum is driven to turn over, which improves the cleaning efficiency and plays a diversion role. When the inner drum rotates until the sealing cover is located at the upper part, the material falls evenly between the plurality of inner extrusion bars, thereby improving the efficiency of breaking up the compacted material.

[0017] Furthermore, a circular groove is opened at the center position of the bottom end of the inner drum, and a mounting box with a closed circular groove is rotatably connected to the inner drum, and the mounting box extends between the outer sleeve and the inner drum. The driving assembly includes an annular driven gear arranged between the outer sleeve and the inner drum and coaxially fixed with the inner drum, and the annular driven gear is arranged outside the mounting box. The outer sleeve is rotatably connected to a connecting shaft, and a driving gear located between the outer sleeve and the inner drum and meshing with the annular driven gear is coaxially nested on the connecting shaft.

The support bar 802 rotates, thereby driving the outer sleeve 1 fixed to the support bar 802 to rotate until the compacted material falls between the inner stirring bar 601 and the outer stirring bar 602. The inner roller 2 continues to rotate, driving the compacted material to move to contact the extrusion bar 603. When the extrusion bar 603 passes through the inner stirring bar 601 and the outer stirring bar 602, it will break up the compacted powdered material between the inner stirring bar 601 and the outer stirring bar 602, thereby reducing the possibility of poor cleaning effect after the powdered material is compacted.
