Description

Technical Field

[0001] This utility model relates to the technical field of cleaning equipment for metal powder processing, and in particular to a self-cleaning metal powder preparation device. Background Technology

[0002] During the production and processing of metal powder, impurity ions, organic pollutants, or other soluble components will be adsorbed. Therefore, it is necessary to clean it by using deionized water. The high purity of deionized water can effectively dissolve and remove these pollutants, ensuring the cleanliness of the powder surface.

[0003] Chinese utility model patent CN203209686U discloses a metal powder cleaning and dehydration device. Cleaning liquid is supplied to a filter bag inside the metal powder chamber to clean the metal powder. The cleaning liquid filtered out by the filter bag enters a water storage chamber below for dehydration, removing impurities mixed in with the metal powder. However, in this prior art, the cleaning liquid enters the filter bag for immersion cleaning of the metal powder, and the cleaning liquid is also filtered out from the filter bag. During immersion cleaning, it is difficult to remove contaminants adhering to the surface of the metal powder, and the cleaning liquid is slowly filtered out into the water storage chamber below, resulting in poor cleaning effect. Furthermore, in existing cleaning equipment, the placement tank for the metal powder is fixed inside the cleaning tank, making the removal of the metal powder inconvenient.

[0004] In view of the above problems, a self-cleaning metal powder preparation device with good cleaning effect and convenient use is designed. Utility Model Content

[0005] In view of the above-mentioned technical problems, this utility model provides a self-cleaning metal powder preparation device, which uses ultrasonic cleaning to clean metal powder. It uses microbubbles to impact the surface of metal powder to remove contaminants, thereby enhancing the cleaning effect. The component for placing metal powder is inserted into the cleaning tank, making it easy to remove the whole device after cleaning. The lid is set to an automatic lifting mode for convenient operation.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A self-cleaning metal powder preparation device is characterized by comprising an ultrasonic cleaning chamber, a chamber lid, a lifting assembly, and a metal powder placement frame assembly. The ultrasonic cleaning chamber has a lid at its top opening, and a positioning groove adapted to a positioning block on the top of the ultrasonic cleaning chamber is located below the lid. The lid is connected to the lifting assembly, which is mounted on the outside of the ultrasonic cleaning chamber. The metal powder placement frame assembly is located inside the cleaning tank of the ultrasonic cleaning chamber.

[0008] The metal powder placement frame assembly consists of a fixed frame, a handle, and a filter frame. The fixed frame has T-shaped strips on both sides, which are inserted into T-shaped grooves on the wall of the cleaning tank. The fixed frame has a handle at its top and a filter frame at its bottom, with the fixed frame and filter frame communicating with each other.

[0009] The lifting assembly consists of a mounting frame, a motor, a lead screw, and a lifting rod. The mounting frame is fixedly installed on the rear side of the ultrasonic cleaning chamber. The lead screw is mounted on the mounting frame via bearings. One end of the lead screw is connected to the output end of the motor. One end of the lifting rod is threaded onto the lead screw, and the other end of the lifting rod is connected to the chamber cover.

[0010] The guide hole on the lifting rod is connected by a guide post, and the two ends of the guide post are respectively fixed to the mounting bracket.

[0011] The ultrasonic cleaning box is equipped with a liquid inlet and a liquid outlet, and both the liquid inlet and the liquid outlet are equipped with control valves.

[0012] Furthermore, a certain gap is provided between the side wall of the filter frame and the inner wall of the cleaning tank, so that the cleaning liquid can easily enter and exit the filter frame.

[0013] Furthermore, the filter frame is provided with filter holes, and the diameter of the filter holes is smaller than the diameter of the metal powder, so that the metal powder cannot pass through the filter frame.

[0014] Furthermore, an ultrasonic generator is installed in the bottom cavity of the ultrasonic cleaning tank. The ultrasonic generator is electrically connected to multiple transducers, which are installed below the cleaning tank.

[0015] Furthermore, the lid of the box is equipped with an observation window to facilitate viewing the internal cleaning process.

[0016] Furthermore, a control panel is installed on the outer wall of the ultrasonic cleaning box. The controller in the control panel is electrically connected to the motor, control valve and ultrasonic generator respectively to control the operation of the equipment.

[0017] The beneficial effects of this utility model are:

[0018] The cleaning equipment designed in this utility model allows for the opening and closing of the lid when it is necessary to open the lid to clean metal powder or remove the cleaned metal powder. The lifting component is activated by the buttons on the control panel, and the motor drives the lead screw to rotate, thereby raising and lowering the lid to complete the opening and closing operation. No manual opening and closing is required from the operator, making it convenient to use.

[0019] The metal placement frame assembly designed in this utility model is inserted into the cleaning tank of an ultrasonic cleaning box. The metal powder is located in the filter screen frame. The diameter of the filter screen frame is set to be smaller than the diameter of the metal powder, so that the metal powder cannot pass through while the cleaning liquid can enter or be filtered out. When cleaning is completed and needs to be removed, the metal placement frame assembly can be taken out of the cleaning tank by opening the box cover and using the handle.

[0020] The cleaning equipment designed in this utility model delivers a cleaning solution containing deionized water into the cleaning tank through the inlet when cleaning metal powder. Then, it starts the ultrasonic cleaning mode, using microbubbles generated by high-frequency vibration to impact and peel off the surface of the metal powder, which can effectively remove the contaminants attached to the surface and enhance the cleaning effect.

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0029] Example 1

[0030] As shown in the figure, the ultrasonic cleaning chamber 1 is equipped with a cleaning tank 11 inside, and an ultrasonic generator 71 is installed in the bottom cavity of the ultrasonic cleaning chamber 1. The ultrasonic generator 71 is electrically connected to multiple transducers 72, which are installed below the cleaning tank 11.

[0031] like Figure 2 The ultrasonic cleaning chamber 1 has a cover 2 at its top opening. Below the cover 2 is a positioning groove that matches the positioning block 112 on the top of the ultrasonic cleaning chamber 1. The cover 2 is connected to a lifting assembly, which is mounted on the outside of the ultrasonic cleaning chamber. A mounting bracket 52 within the lifting assembly is fixedly mounted on the rear side of the ultrasonic cleaning chamber 1. A lead screw 53 is mounted on the mounting bracket 52 via bearings. One end of the lead screw 53 is connected to the output end of a motor 51. One end of a lifting rod 54, which is connected to the cover 2, is threaded onto the lead screw 53. Furthermore, a guide post 55 penetrates a guide hole in the lifting rod 54, and both ends of the guide post 55 are fixed to the mounting bracket 52.

[0032] like Figure 3 and 4The ultrasonic cleaning chamber 1 has a metal powder placement frame assembly in its cleaning tank 11. The metal powder placement frame assembly consists of a fixed frame 61, a handle 63, and a filter screen frame 62. The fixed frame 61 has T-shaped strips on both sides, which are inserted into T-shaped grooves 111 on the wall of the cleaning tank 11. The fixed frame 61 has a handle 63 on its top and a filter screen frame 62 at its bottom. The fixed frame 61 is connected to the filter screen frame 62. A certain distance is provided between the side wall of the filter screen frame 62 and the inner wall of the cleaning tank 11, so that the cleaning liquid can easily enter and exit the filter screen frame 62. The filter screen frame 62 has filter holes with a diameter smaller than that of the metal powder, so that the metal powder cannot pass through the filter screen frame 62.

[0033] Furthermore, an observation window 21 is provided on the lid 2 for easy viewing of the internal cleaning process. The ultrasonic cleaning chamber 1 has an inlet 12 and an outlet 13, both equipped with control valves 3. A control panel 4 is also installed on the outer wall of the ultrasonic cleaning chamber 1. The controllers within the control panel 4 are electrically connected to the motor 51, the control valves 3, and the ultrasonic generator 71, thereby enabling control of the equipment's operation via the control panel. Since the control circuit for operating electronic components is a well-known technique in the existing field, its details will not be elaborated upon in this application.

[0034] Example 2

[0035] In use, the operator controls the lifting assembly via buttons on the control panel. Motor 51 drives screw 53 to rotate, which in turn raises and lowers lifting rod 54, thus lifting and lowering the lid 2, completing the opening and closing operation. No manual opening and closing is required, making it convenient to use.

[0036] After opening the lid 2, pour the metal powder to be cleaned into the filter frame 62 in the metal powder placement frame assembly, close the lid 2, and deliver the cleaning solution containing deionized water into the cleaning tank 11 through the liquid inlet 12. Then, start the ultrasonic cleaning mode, using the micro bubbles generated by high-frequency vibration to impact and peel off the surface of the metal powder, which can effectively remove the contaminants attached to its surface and enhance the cleaning effect.

[0037] After cleaning, activate the control valve 3 at the drain port 13 to open it, and the cleaning liquid will slowly drain out. Since the metal powder is placed in the filter screen frame 62, the pore size of the filter screen frame 62 is set to be smaller than the diameter of the metal powder, so that the metal powder cannot pass through while the cleaning liquid can be filtered out. After dehydration, after opening the box cover, the entire metal placement frame assembly can be taken out from the cleaning tank 11 by using the handle 63.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
