Description

Technical Field

[0001] The utility model relates to the technical field of TiCN powder, in particular to a TiCN powder manufacturing device. Background Art

[0002] TiCN is a chemical substance also known as titanium carbide nitrogen or titanium carbonitride, and is a dark gray powder. TiCN coatings have demonstrated excellent performance in industrial applications, particularly in improving productivity and surface quality. Wet ball mills, used for powder production, are also frequently used in the manufacture of TiCN powders. These new ball mills utilize specialized rolling bearings as the support structure for the cylinder. Designed according to a novel concept, these mills feature several protective liners fixed to the inner wall of the cylinder. These liners are frequently impacted by the grinding balls, making them susceptible to damage and requiring regular inspection and replacement.

[0003] However, the cylinder of the current wet ball mill is generally an integrated design. Therefore, each time the internal lining of the cylinder is inspected and replaced, it is necessary to remove all the bolts on the flanges at both ends of the entire cylinder and completely expose the openings at both ends of the cylinder before the lining inside the cylinder can be replaced, which makes the replacement of the lining inside the wet ball mill cylinder more complicated. Utility Model Content

[0004] The purpose of the utility model is to solve the problem of relatively complicated replacement of the inner lining plate of the wet ball mill barrel in the prior art, and to propose a TiCN powder manufacturing device.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0006] The TiCN powder manufacturing device includes a wet ball mill cylinder, wherein the wet ball mill cylinder includes two coaxially symmetrical flanges, two or more arc-shaped assembled cylinder plates, and a plurality of combined liner plates;

[0007] Several arc-shaped assembled cylinder plates are evenly arranged in a cylindrical shape with the central axis of the two flanges as the center of the circle. The two ends of the arc-shaped assembled cylinder plates are detachably mounted on the two flanges respectively, and several combined lining plates are respectively mounted on the inner walls of several arc-shaped assembled cylinder plates.

[0008] Preferably, the combined lining plate comprises a hard sealing gasket and an arc-shaped plate body that fit together, and the hard sealing gasket is fit-fitted on the inner wall of the arc-shaped assembled cylinder plate.

[0009] Preferably, the hard sealing gasket includes a plurality of alloy steel ring pieces and a plurality of rubber ring pieces, and the plurality of alloy steel ring pieces and the plurality of rubber ring pieces are alternately overlapped and connected.

[0010] Preferably, a positioning cylinder is coaxially mounted on opposite ends of the two flanges, and both ends of the arc-shaped assembled cylinder plate are provided with a positioning sealing groove that is engaged with the outer wall of the positioning cylinder.

[0011] Preferably, the periphery of the two positioning cylinders is provided with several groups of positioning screws, and the positioning screws are composed of three mutually parallel threaded rods. The two ends of the arc-shaped assembled cylinder plate are respectively provided with two mounting holes corresponding to the three threaded rods in each group of positioning screws.

[0012] Preferably, bolts are coaxially installed in the second circular hole in the combined liner plate and the first mounting hole in the arc-shaped assembled cylinder plate.

[0013] Compared with the prior art, the present invention provides a TiCN powder manufacturing device with the following beneficial effects:

[0014] 1. The TiCN powder manufacturing device adopts a modular and detachable design for the wet ball mill cylinder. Compared with the modular liner in the traditional integrated ball mill cylinder, it is easier to disassemble and install. One arc-shaped assembled cylinder plate can be disassembled separately, and the modular liner on the arc-shaped assembled cylinder plate or the adjacent arc-shaped assembled cylinder plate can be replaced.

[0015] 2. The TiCN powder manufacturing device can absorb the impact force of weakened grinding balls on the combined liner through the high damping elasticity of several rubber rings of the hard sealing gasket in the combined liner, thereby reducing the damage to the arc plate body in the combined liner caused by vibration and increasing the service life of the arc plate body. In addition, the arc-shaped assembled cylinder plate is isolated by the high damping of multiple rubber rings to reduce the impact of the arc plate body on the arc-shaped assembled cylinder plate, which also increases the service life of the arc-shaped assembled cylinder plate.

Therefore, they cannot be understood as limitations on the present invention.

[0023] Refer to the attached Figure 1-4 The TiCN powder manufacturing device includes a wet ball mill cylinder 1, which is mainly composed of two symmetrically coaxial flanges 11, six arc-shaped assembled cylinder plates 14 and a plurality of combined liners 16. The six arc-shaped assembled cylinder plates 14 are evenly arranged in a cylindrical shape with the central axes of the two flanges 11 as the center of the circle. The two ends of the arc-shaped assembled cylinder plates 14 are detachably installed between the two flanges 11. After the six arc-shaped assembled cylinder plates 14 are completely assembled into a cylindrical shape, every two adjacent arc-shaped assembled cylinder plates 14 are seamlessly contacted and connected.

[0024] In this embodiment, the opposite ends of the two flanges 11 are coaxially fixedly installed with a positioning tube 12, and the inner sides of both ends of the arc-shaped assembled cylinder plate 14 are provided with two positioning sealing grooves 19 that are engaged with the outer wall of the positioning tube 12 on one side of the flange 11. Six groups of positioning screws are evenly arranged on the periphery of the positioning cylinder 12, and each group of positioning screws is composed of three mutually parallel threaded rods 13 arranged in a herringbone shape. The head end of the threaded rod 13 is fixedly installed on the periphery of the positioning cylinder 12, and the positioning sealing grooves 19 at both ends of each arc-shaped assembled cylinder plate 14 are provided with three mounting holes 2 18 corresponding to one group of positioning screws, that is, the six mounting holes 2 18 at both ends of the arc-shaped assembled cylinder plate 14 can be positioned through the three threaded rods 13 on the two positioning cylinders 12 respectively, and engaged and installed on the outer walls of the two positioning cylinders 12. At the same time, the end of the threaded rod 13 is threadedly installed with a nut 17, that is, the two ends of the arc-shaped assembled cylinder plate 14 are fixedly installed on the two positioning cylinders 12 by three threaded rods 13 and three nuts 17 respectively.

[0025] In this embodiment, a number of combined liners 16 are arranged and installed on the inner walls of six arc-shaped assembled cylindrical plates 14 by means of two bolts 10 and two nuts 20 respectively. Each arc-shaped assembled cylindrical plate 14 is provided with a mounting hole 15 corresponding to the number of combined liners 16. A number of bolts 10 are sealed and passed through the number of mounting holes 15 respectively. The two nuts 20 are threadedly installed on the end of the bolts 10. When the arc-shaped assembled cylindrical plates 14 are disassembled and installed, the arc-shaped assembled cylindrical plates 14 can be clamped by a vacuum suction cup, or a handle can be fixed on the outer wall of the arc-shaped assembled cylindrical plates 14.

[0026] In this embodiment, the combined liner 16 includes an arc-shaped plate body 162 and a hard sealing gasket 161. The hard sealing gasket 161 is sealingly fitted and fixedly installed on the inner wall of the arc-shaped plate body 162. The hard sealing gasket 161 is mainly used to increase the sealing between the combined liner 16 and the inner wall of the arc-shaped assembled cylinder plate 14. The arc-shaped plate body 162 and the rubber gasket 1611 in the hard sealing gasket 161 are respectively provided with two circular holes 164 and two circular holes 1612. The ends of the two circular holes 164 on the arc-shaped plate body 162 are both provided with circular grooves 163 with an inner diameter expanding outward. The end of the bolt 10 passes through the circular groove 163, the circular hole 1612 and the mounting hole 15 in sequence. The nut 20 is tightened along the bolt 10 on the outer wall of the arc-shaped assembled cylinder plate 14. The bolt 10 is coaxially arranged with the circular hole 1612, the mounting hole 15 and the mounting hole 2 18 respectively.

[0027] In this embodiment, the hard sealing gasket 161 also includes several alloy steel ring pieces 1613 and several rubber ring pieces 1614, and the several alloy steel ring pieces 1613 and the several rubber ring pieces 1614 are alternately overlapped and connected by glue. The outer sides of the two ends of the hard sealing gasket 161 are respectively the alloy steel ring piece 1613 and the rubber ring piece 1614, and the rubber ring piece 1614 is arranged at one end away from the arc-shaped plate body 162, that is, after the combined lining plate 16 is installed on the inner wall of the arc-shaped assembled cylinder plate 14, the outermost rubber ring piece 1614 in the combined lining plate 16 is fitted with the inner wall of the arc-shaped plate body 162, and the two ends of the rubber gasket 1611 are glued and The inner walls of an alloy steel ring piece 1613 and several rubber ring pieces 1614 are connected, and multiple layers of rubber ring pieces 1614 are provided in the hard sealing gasket 161 to ensure that the hard sealing gasket 161 has a sufficient compression range. The combined liner 16 utilizes the high damping elasticity of the rubber ring piece 1614 to absorb the impact force of the weakened grinding ball on the combined liner 16. Firstly, it can increase the service life of the combined liner 16, and secondly, it can increase the service life of the arc-shaped assembled cylinder plate 14. The alloy steel ring piece 1613 is mainly used to increase the mechanical strength of several rubber ring pieces 1614, which can effectively prevent the rubber ring piece 1614 from being damaged by the impact of the grinding ball.

[0028] The present invention has the advantages that the wet ball mill cylinder 1 adopts a modular detachable design, which is easier to disassemble and install than the liner in the traditional one-piece ball mill cylinder. Because the liner in the general one-piece ball mill cylinder requires the entire cylinder to be disassembled before the modular liner 16 inside the cylinder can be replaced, the present application only needs to disassemble 2 to 3 adjacent arc-shaped assembled cylinder plates 14, and there is enough space to replace all the modular liner plates 16. At the same time, a single arc-shaped assembled cylinder plate 14 can also be disassembled in a targeted manner to replace the modular liner 16 on the arc-shaped assembled cylinder plate 14 or on the adjacent arc-shaped assembled cylinder plates 14.

[0029] The second is to replace the traditional integrated liner with a combined liner 16 consisting of a hard sealing gasket 161 and an arc-shaped plate body 162. The combined liner 16 is used to absorb the impact force of the weakened grinding ball on the combined liner 16 through the high damping elasticity of several rubber ring pieces 1614 in the hard sealing gasket 161, thereby reducing the damage to the arc-shaped plate body 162 in the combined liner 16 caused by vibration force and increasing the service life of the arc-shaped plate body 162. In addition, the arc-shaped assembled cylinder plate 14 is isolated by the high damping of multiple rubber ring pieces 1614 to reduce the impact of the arc-shaped plate body 162 on the arc-shaped assembled cylinder plate 14, which also increases the service life of the arc-shaped assembled cylinder plate 14. In addition, the several alloy steel ring pieces 1613 alternately overlapping on both sides of the above-mentioned several rubber ring pieces 1614 increase the mechanical strength of the several rubber ring pieces 1614, which can effectively prevent the rubber ring pieces 1614 from being damaged by the impact of the grinding balls.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
