TECHNICAL FIELD
[0001] The utility model relates to the field of metal powder metallurgy technology, more specifically, it relates to an automatic cleaning device for a powder metallurgy atomization tower. BACKGROUND
[0002] In 2002, a research and development team led by Professor Chen Zhenhua of Hunan University invented a new three-phase flow atomization method, namely solid-gas atomization, by drawing on the principles of water-gas combined atomization technology. Solid-gas atomization involves adding NaCl powder to the atomization gas stream to increase the impact momentum of the gas stream. High-speed solid-gas mixed two-phase flow is ejected from the atomization nozzle, directly breaking up the liquid metal to produce powder. The solid salt and powder are separated through washing, filtering, and drying. This method improves the yield of fine powder while not significantly affecting the purity of the powder.
[0003] This method has a phenomenon where a portion of the mixed NaCl powder enters the washing, filtering, and drying processes along with the atomized metal powder, and a portion is adsorbed and accumulated on the inner walls and corners of the atomization tower. If not cleaned in a timely manner, this not only affects the purity of the product but also increases the production burden. Therefore, a device is needed to clean the NaCl powder agglomerates and other pollution sources, taking into account the characteristics of the powder metallurgy atomization tower. SUMMARY

[0017] Example:
[0018] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.
[0019] Automatic cleaning devices for powder metallurgy atomization towers, such as... Figure 1 As shown, the basic component is the main upright 1. The top of the main upright 1 is equipped with a drive assembly—a rotary motor 2 with a fixed bracket and a telescopic cylinder 3 with a central through-hole. The bracket on the rotary motor 2 is the point of force providing rotational drive to the rotary motor 2 after the entire device enters the cleaning station of the atomizing tower. The output end of the rotary motor 2 connects to the top of the main upright 1. The through-hole design of the telescopic cylinder 3 facilitates the passage and fixation of the main upright 1. All components except the rotary motor 2 rotate together with the main upright 1. From top to bottom, the main upright 1 has an extension seat 5 and a fulcrum seat 4. The fulcrum seat 4 is fixed to the lower end of the main upright 1, and the extension seat 5 slides on the upper end of the main upright 1. The telescopic cylinder 3 and the extension seat 5 are connected. The fulcrum seat 4 has a synchronous transmission module, and the extension seat 5 has an extension module. A horizontally retractable chassis module is fixed to the bottom of the main upright 1. The extension module and the chassis module are connected via the synchronous transmission module. Both the end of the extension module and the bottom of the chassis module are equipped with corresponding scraping parts 6. The rotary motor 2 drives the main upright 1, extension seat 5, fulcrum seat 4, extension module, chassis module, synchronous transmission module, and telescopic cylinder 3 to rotate together. Starting with the extension and retraction of the telescopic cylinder 3, the extension seat 5 is first moved up and down along the main upright 1. The movement of the extension seat 5 causes the extension or retraction of the extension module. This extension or retraction action of the extension module, through the synchronous transmission module, causes the chassis module to extend and retract laterally. The extension and retraction range of the chassis module must ensure that the total width of the chassis module is consistent with the total width of the extension module; that is, the lateral range of the extension module is the same as the lateral range of the chassis module.
[0020] Specifically, such as Figure 1 As shown, the stretching module includes two stretching rods 7 and two stretching bases 8. The stretching rods 7 are symmetrically hinged to both ends of the stretching base 5, and the ends of the stretching rods 7 are individually hinged to their corresponding stretching bases 8. The outer contact surface of the stretching base 8 is provided with a scraping element 6. The chassis module includes a chassis shell 11 and two sliding discs 12, which are slidably connected to the chassis shell 11. Figure 3As shown, the two ends of the chassis shell 11 are provided with continuous and through sliding grooves 13, the sliding grooves 13 pass through the top surface of the chassis shell 11 upward, leaving a sliding space for the hinge joint 14 on the sliding disc 12, and the hinge joint 14 is used for connecting the synchronous transmission module. The sliding disc 12 is arranged in the sliding groove 13, and the sliding disc 12 and the chassis shell 11 are both provided with the wiper 6. The wiper 6 is made of soft and elastic material, and the end is spherical. The sliding disc 12 is provided with an array of sliding grooves at the bottom, which pass through the two ends and are used for the wiper 6 on the sliding disc 12 to pass through and slide freely. As shown Figure 2 As shown, the wiper 6 at the bottom of the sliding disc 12 and the wiper 6 at the bottom of the chassis shell 11 are arranged in staggered positions, and the extension or retraction of the sliding disc 12 will not affect the cleaning action of the wiper 6 at the bottom. The end of the sliding disc 12 is provided with symmetrical clamping blocks, and the sliding groove 13 is provided with corresponding recessed grooves, and the clamping blocks are embedded in the recessed grooves, which play a guiding and limiting role. The synchronous transmission module includes two hinge rods 9 and two transmission rods 10, the hinge rods 9 are symmetrically hinged at the two ends of the fulcrum seat 4, and the other end of the hinge rod 9 is sleeved on the corresponding stretching rod 7. The two transmission rods 10 are symmetrically hinged on the hinge joint 14 of the sliding disc 12, and the other end of the transmission rod 10 is hinged on the corresponding hinge rod 9.
[0021] The extension cylinder 3 drives the stretching seat 5 to descend, the stretching rod 7 is passively stretched and opened, the sliding end of the hinge rod 9 slides to the outside, the bottom end of the transmission rod 10 moves outward with a tendency to fall, drives the sliding disc 12 to extend from the sliding groove 13, and the hinge joint 14 slides in the through groove on the top surface of the chassis shell 11. The sliding disc 12 extends outward and is consistent with the opening pace of the stretching rod 7, which ensures that the wiper 6 on the stretching base 8 contacts the side wall of the atomizing tower, and the wipers 6 at the bottom of the chassis shell 11 and the sliding disc 12 also contact the bottom of the atomizing tower, and then driven by the rotating motor 2, the inside of the atomizing tower is cleaned at high speed.
[0022] It should be noted that the specific embodiments are only an explanation of the present application, and are not a limitation of the present application. Those skilled in the art can make non-creative modifications to the embodiments according to the needs after reading the specification, but as long as the modifications are within the scope of the claims of the present application, they are protected by the patent law.
