Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy equipment maintenance technology, specifically an auxiliary cleaning device for vacuum atomizing powder making furnaces. Background Technology

[0002] In the vacuum atomization powder metallurgy industry, after smelting and atomization, dust adheres to the inner walls of the straight barrel and lower conical barrel of the atomization chamber. Due to gravity, the adhesion is more severe in the lower conical barrel. To ensure the quality of each batch of atomized powder, the straight barrel and lower conical barrel need to be disassembled and cleaned regularly. The traditional method for cleaning the lower conical barrel involves workers using a hydraulic trolley to disassemble it, manually wiping it clean, and then reinstalling it. Because the lower conical barrel is heavy, manual lifting and moving is difficult and may cause it to tip over or fall off, posing a safety hazard. As for the inner wall of the straight barrel, operators usually use an extension pole with a cloth tied to it to wipe it, which is difficult to achieve the desired cleaning effect. Utility Model Content

[0003] The purpose of this invention is to provide an auxiliary cleaning device for vacuum atomizing powder making furnaces, which can solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary cleaning device for a vacuum atomizing powder maker, comprising a first auxiliary cleaning mechanism and a second auxiliary cleaning mechanism. The first auxiliary cleaning mechanism is used for auxiliary cleaning of the lower conical section atomizing chamber, including a fork-tooth plate matched to the outer wall of the lower conical section atomizing chamber and a first driving part for driving the fork-tooth plate to move. The first driving part includes a moving trolley and a combined screw lifting platform fixedly connected to the top of the moving trolley. The fork-tooth plate is connected to the output end of the combined screw lifting platform. The second auxiliary cleaning mechanism is located on the side of the moving trolley and is used for auxiliary cleaning of the straight barrel section atomizing chamber. It includes a movable mounting platform and a lift fixedly connected to the top of the mounting platform. The lift is equipped with an operating compartment for workers to stand in.

[0005] In a preferred embodiment, the mobile trolley is configured with an upper carrying space and a lower carrying space distributed vertically, the upper carrying space being constructed as a water storage tank structure with an open top. The water storage tank is used to collect the cleaning wastewater from the lower cone-shaped atomization chamber and discharge it centrally through the tank's drain outlet.

[0006] In a preferred embodiment, the outer surface of the water storage tank is provided with multiple compartments for holding storage tools.

[0007] In a preferred embodiment, the bottom of the mobile trolley is connected to a roller assembly, which includes two omnidirectional rollers and two directional rollers connected to the bottom of the mobile trolley. The directional rollers are driven by a second drive motor fixedly connected to the mobile trolley. By setting up this roller assembly, it is possible to prevent the mobile trolley from sliding sideways during the transport of the lower conical atomizing chamber and to optimize turning control.

[0008] In a preferred embodiment, each end of the mounting platform is hinged with a lever arm, and the end of the lever arm is connected to a vertically arranged adjustment seat. The lever arm configuration increases the force-bearing area, forming an anti-overturning torque and mitigating the risk of tipping over due to the upward shift of the operating compartment's center of gravity.

[0009] In a preferred embodiment, the height of the adjustment seat is adjustable to adapt to the movement and support states of the mechanism.

[0010] In a preferred embodiment, the operating compartment is connected to a fan and an oxygen content monitor. The fan increases airflow and replenishes oxygen; the oxygen content monitor alerts the user to low-oxygen environments, ensuring safe operation.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The auxiliary cleaning device for vacuum atomizing powder making furnace provided by this utility model can safely disassemble the lower cone barrel through the first auxiliary cleaning mechanism, and the constructed water storage tank and mobile vehicle body meet the needs of fixed-point cleaning. Combined with the second auxiliary cleaning mechanism, it can expand the cleaning function of the inner wall of the straight barrel, solving the problems of high risk of manual handling and sewage splashing. It is particularly suitable for the field of powder metallurgy equipment maintenance. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] like Figure 1 As shown, in the prior art, the vacuum atomizing powder maker includes a straight cylindrical atomizing chamber 1 and a lower conical atomizing chamber 2. The lower conical atomizing chamber 2 is detachably connected to the bottom end of the straight cylindrical atomizing chamber 1. During cleaning, the lower conical atomizing chamber 2 needs to be removed from the fixed straight cylindrical atomizing chamber 1. Then, the straight cylindrical atomizing chamber 1 and the lower conical atomizing chamber 2 are cleaned separately before being reassembled.

[0022] See Figure 2 The auxiliary cleaning device for a vacuum atomizing powder maker disclosed in this embodiment includes a first auxiliary cleaning mechanism 3 and a second auxiliary cleaning mechanism 4. The first auxiliary cleaning mechanism 3 is used for auxiliary cleaning of the lower cone section atomizing chamber 2, and the second auxiliary cleaning mechanism 4 is used for auxiliary cleaning of the straight barrel section atomizing chamber 1.

[0023] Specifically, in combination Figure 3 The first auxiliary cleaning mechanism 3 includes a fork plate 31 matched with the outer wall of the lower conical section atomizing chamber 2 and a first driving part for driving the movement of the fork plate 31. Correspondingly, a receiving flange 21 is fixedly provided on the outer wall of the lower conical section atomizing chamber 2 in the circumferential direction, and the fork plate 31 can abut against the receiving flange 21.

[0024] The first drive unit includes a mobile trolley 32. In this embodiment, the mobile trolley 32 has a regular rectangular structure, consisting of a support frame formed by four sets of vertical square tubes 321 and several sets of horizontal square tubes, and has an upper support space 33 and a lower support space 34 distributed vertically. The first drive unit also includes a combined screw lifting platform 35 fixedly connected to the top of the mobile trolley 32. A fork plate 31 is disposed above the combined screw lifting platform 35 and fixedly connected to its output end. The combined screw lifting platform 35 adopts existing technology, in which the first drive motor 351 drives the worm gear force steering device 352 through a coupling, thereby driving each worm screw jack 353 to rise and fall, and thus controlling the rise and fall of the fork plate 31. The first drive motor 351 is supported and fixed by a fixing plate fixedly connected to the side of the mobile trolley 32, and each set of worm screw jacks 353 is respectively connected to each vertical square tube 321.

[0025] In this embodiment, the bottom of the mobile trolley 32 is connected to a roller assembly. That is, pushing the mobile trolley 32 can move the fork plate 31 closer to or away from the lower conical section atomizing chamber 2, and the fork plate 31 is driven to rise and fall by the combined screw lifting platform 35. In actual application, the operator pushes the mobile trolley 32 to the bottom of the lower conical section atomizing chamber 2, and then drives the fork plate 31 to rise by the combined screw lifting platform 35 until it abuts against the receiving flange 21 of the lower conical section atomizing chamber 2. At this time, the robot or operator removes the lower conical section atomizing chamber 2 from the straight barrel section atomizing chamber 1, the fork plate 31 drives the lower conical section atomizing chamber 2 to fall, and the operator then pushes the mobile trolley 32 to the designated cleaning position.

[0026] Furthermore, the upper support space 33 is constructed as a top-opening water storage tank structure, which can collect the cleaning wastewater from the lower conical atomizing chamber 2 and discharge it centrally through the drain outlet of the water storage tank, which extends from the lower support space 34. Preferably, the outer side of the water storage tank is provided with multiple compartments 36 for storing and storing tools, so as to facilitate access by operators and improve work efficiency. For example, the stored tools can be water guns, air guns, dismantling tools, etc.

[0027] To prevent the mobile trolley 32 from sliding sideways during the transport of the lower conical atomizing chamber 2 and to optimize turning control, in this embodiment, the roller assembly includes two universal rollers 372 and two directional rollers 371 fixedly connected to the bottom of the mobile trolley 32 via a fixing plate. The universal rollers 372 are equipped with brake pads, and the two directional rollers 371 are connected by two couplings and a shaft. One of the directional rollers 371 is driven by a second drive motor 373 fixedly connected to the lower bearing space 34. The second drive motor 373 and the directional rollers 371 cooperate through a sprocket and chain structure 374.

[0028] In this embodiment, the mobile trolley 32 is also provided with a push handle 38, and the push handle 38 is provided with a limit switch 39 that is linked to the second drive motor 373. The movement of the mobile trolley 32 is controlled by controlling the extension and retraction of the limit switch 39. The structure and control method of the limit switch 39 in this embodiment are existing technologies and will not be described in detail here.

[0029] Combination Figure 2 and Figure 4 The second auxiliary cleaning mechanism 4 is located on the side of the mobile trolley 32, including an installation platform 41 that is roughly flat with the bottom surface of the mobile trolley 32, and a lift 42 fixedly connected to the top of the installation platform 41. The lift 42 has an operating cabin 421 for workers to stand in. The lift 42 can control the lifting and lowering of the operating cabin 421, facilitating the movement of workers to clean the straight-barrel section atomization chamber 1. The lift 42 adopts existing technology; for example, it can be an electrically or hydraulically controlled lifting platform, aerial work platform, or work vehicle.

[0030] The bottom of the mounting platform 41 is provided with two sets of rolling wheels 43, and the two sides of the mounting platform 41 are respectively hinged with adjustable seats 45 for support. Specifically, the two ends of the side of the mounting platform 41 are respectively hinged with lever arms 44 of a predetermined length through hinge shafts. The end of the lever arm 44 is provided with a threaded hole, and the vertically arranged adjustable seat 45 is threaded through the threaded hole. This threaded structure makes the height of the adjustable seat 45 adjustable. The four sets of adjustable seats 45 make the mounting platform 41 form a stable support platform, thereby providing stable support for the elevator 42.

[0031] It should be noted that as the center of gravity of the operating box 421 moves upward, the overall overturning moment of the mechanism will increase. In this embodiment, the force-bearing area can be increased by setting the lever arm 44 to form an anti-overturning couple, thereby ensuring operational safety.

[0032] like Figure 4 As shown, the control compartment 421 is also connected to a fan 46 and an oxygen content monitor 47 to ensure the safety of the operators. The fan 46 is used to increase the airflow and supplement oxygen. The oxygen content monitor 47 adopts existing technology and is used to indicate a low oxygen environment.

[0033] In practical application, the auxiliary cleaning device is moved to the bottom of the atomizing chamber, and the fork plate 31 is raised to engage with the receiving flange 21 of the lower conical section atomizing chamber 2. The mounting bolts of the lower conical section atomizing chamber 2 and the straight barrel section atomizing chamber 1 are loosened, and the fork plate 31 drives the lower conical section atomizing chamber 2 to descend. The operator operates the push handle 38 to push the moving trolley 32 to the designated cleaning position. Then, the second auxiliary cleaning mechanism 4 is pushed to the bottom of the straight barrel section atomizing chamber 1, and the elevator 42 is started to move the operating chamber 421 to the straight barrel section atomizing chamber 1. The operator then cleans the inner wall of the barrel. During the process, the fan 46 is started to increase the airflow. The oxygen content monitor 47 monitors the oxygen content of the working environment to ensure safe operation.
