Description

Technical Field

[0001] The present utility model relates to the field of machinery, in particular to a cleaning waste grinding barrel for the fastener industry in laboratory scenarios, and more particularly to a simulation device for a laboratory waste cleaning grinding barrel. Background Art

[0002] In the production process of fasteners, the waste cleaning grinding barrel is one of the key equipment, and the working conditions such as the tumbling state and rotation speed of the internal materials directly affect the cleaning quality and subsequent machining accuracy of the fasteners. At present, most of the waste cleaning grinding barrels used in industrial sites are large drum structures, which realize the tumbling and cleaning of materials by the rotation of the drum.

[0003] However, when carrying out process optimization, parameter debugging or fault analysis in the laboratory, there is a technical problem that the on-site working conditions cannot be accurately simulated. Among the existing laboratory equipment, there is a lack of a simulation device matching the structure and operating parameters of the on-site grinding barrel. Ordinary stirring equipment cannot achieve the drum-type tumbling effect, small cylindrical drum devices are difficult to simulate the tumbling state of the on-site grinding barrel, and key parameters such as capacity, rotation speed and load cannot be matched 1:1 with the site. For example, the capacity of the on-site grinding barrel is usually hundreds of liters to several cubic meters, loading hundreds of kilograms of parts, while the laboratory uses a small-capacity simulation device of about 500ml, loading fewer parts. This difference in working conditions makes it difficult for the laboratory grinding barrel to simulate the tumbling state of the on-site grinding barrel, resulting in a large deviation between the process parameters obtained in the laboratory and the actual on-site application, making it difficult to test the cleaning ability of the chemical agent, which seriously affects the R&D efficiency and the accuracy of achievement transformation. Contents of the Utility Model

[0004] The purpose of the present utility model is to provide a simulation device for a laboratory waste cleaning grinding barrel, which is used to solve the technical problem in the prior art that the laboratory grinding barrel is difficult to simulate the tumbling state of the on-site grinding barrel.

[0005] This utility model provides a laboratory waste cleaning and grinding barrel simulation device, including a base frame. The left front end of the base frame is fixedly connected to the lower end of a first inclined rod, and the left rear end of the base frame is fixedly connected to the lower end of a second inclined rod. The upper ends of the first and second inclined rods are fixedly connected, and a first bearing seat is fixedly installed at the connection between the upper ends of the first and second inclined rods. The right front end of the base frame is fixedly connected to the lower end of a third inclined rod, and the right rear end of the base frame is fixedly connected to the lower end of a fourth inclined rod. The upper ends of the third and fourth inclined rods are fixedly connected, and a second bearing seat is fixedly installed at the connection between the upper ends of the third and fourth inclined rods. A first bearing is installed in a bearing housing, a second bearing is installed in a second bearing housing, a first rotating shaft is installed in the first bearing, a second rotating shaft is installed in the second bearing, and a roller is arranged between the first and second rotating shafts. The first and second rotating shafts are fixedly connected to the two end faces of the roller, respectively. A fixed seat is provided on the right side of the base frame, and a motor is installed on the fixed seat. The output shaft of the motor is connected to the second rotating shaft through a coupling. The radial cross-section of the roller is a regular polygon with at least five sides. At least three ribs are evenly spaced along the circumference on the inner wall of the roller, and the length direction of the ribs is parallel to the axial direction of the roller. A feed inlet is provided on the side of the roller, and a sealing cover is provided at the feed inlet.

[0006] Preferably, the output shaft of the motor is connected to a coupling via a speed reducer.

[0007] Preferably, the regular polygon has six sides.

[0008] Preferably, the rib is located in the middle of the edge of the regular polygon or at the intersection of the edges.

[0009] Preferably, the sealing cover has a sealing strip around its outer periphery. One end of the sealing cover is hinged to the roller, and the other end is connected to the roller via a rotary switch. When the rotary switch is open, the sealing cover can be opened from the outside; when the rotary switch is closed, the sealing cover is locked to the roller and cannot be opened.

[0010] Compared with existing technologies, this invention offers positive and significant advantages. As rotation proceeds, the parts tumble violently at the polygonal edges under the influence of gravity. Multiple raised ribs on the inner wall of the drum enhance the material lifting effect; as the drum rotates, these ribs carry more material upwards, preventing relative sliding between the material and the drum wall. When the material is lifted to a high point, it is thrown or slid off the ribs under gravity. This discontinuous, periodic lifting and falling process greatly enhances the stirring, mixing, and collision effects on the material, effectively simulating the tumbling state of materials in a large industrial grinding drum.

A first bearing is installed in a second bearing housing 7, a first rotating shaft 8 is installed in the first bearing, and a second rotating shaft 9 is installed in the second bearing. A roller 10 is arranged between the first rotating shaft 8 and the second rotating shaft 9. The first rotating shaft 8 and the second rotating shaft 9 are fixedly connected to the end faces of the roller 10 respectively. A fixed seat (not shown in the figure) is arranged on the right side of the base frame 5. A motor (not shown in the figure) is arranged on the fixed seat. The output shaft of the motor is connected to the second rotating shaft 9 through a coupling. The radial cross section of the roller 10 is a regular polygon with at least five sides. At least three ribs 11 are evenly spaced along the circumference on the inner wall of the roller 10. The length direction of the ribs 11 is parallel to the axial direction of the roller 10.

[0020] Specifically, all parts of this utility model that are not described in detail adopt well-known solutions in the prior art, which are understood and implemented by those skilled in the art, and will not be described in detail here.

[0021] The working principle of this utility model:

[0022] Open the sealing cover 12, add parts, chemical reagents, etc. to the drum 10, close the sealing cover 12, and start the motor. The motor's output shaft drives the drum 10 to rotate via the second rotating shaft 9.

The base frame 5, the first diagonal rod 1, the second diagonal rod 2, the third diagonal rod 3, and the fourth diagonal rod 4 constitute a stable support. The radial cross-section of the drum 10 adopts a regular polygonal design, replacing the cylindrical shape of traditional small laboratory devices. When the drum 10 rotates, the polygonal structure on its inner wall periodically lifts the material to a certain height. As the rotation continues, the parts tumble violently at the edges of the polygon under the action of gravity. Multiple ribs 11 on the inner wall of the drum 10 enhance the lifting effect of the material. When the drum 10 rotates, the ribs 11 can carry more material upwards, preventing relative sliding between the material and the drum wall. When the material is lifted to a high point, it is thrown or slid off the ribs 11 under the action of gravity. The discontinuous, periodic lifting and falling process described above greatly enhances the stirring, mixing and collision of materials, effectively simulating the tumbling state of materials in a large grinding barrel in an industrial setting.
