Description

Technical Field

[0001] This invention relates to the field of alumina drying and cleaning technology, specifically to a dual ultrasonic vacuum drying and cleaning device. Background Technology

[0002] Alumina powder is used in the manufacture of dental cement, porcelain, paint fillers, mordants, and metallic aluminum. It can be added to various water-based resins, plastics, and rubbers to significantly improve the hardness of the materials. It can also be used for heat conduction, polishing, electroplating, and as a catalyst.

[0003] The preparation of alumina powder usually involves crushing the raw materials, separating the alumina using chemical reagents, washing and drying the obtained alumina to remove impurities using drying and cleaning equipment, and finally obtaining the desired alumina powder.

[0004] However, because alumina is hygroscopic, drying it under normal atmospheric pressure is often incomplete. The usual approach is to separate washing and drying using different equipment. First, the chemical reagents on the alumina powder are cleaned off using ultrasonic waves. Then, the cleaned alumina powder is transferred to a drying device in a vacuum environment for drying. This drying and cleaning method not only leads to low work efficiency, but also easily causes leakage of washing water containing detergents and some chemicals during the process of transferring the cleaned alumina powder to the drying equipment.

[0034] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] like Figure 1 and Figure 2 As shown, a dual ultrasonic vacuum drying and cleaning device includes a fixed frame 1, and a fixed cylinder 2 is fixedly connected to the inner side of the fixed frame 1.

[0036] The loading mechanism 5 is used to load alumina powder, and the fixed frame 1 is equipped with a loading mechanism 5 that moves up and down.

[0037] The lifting mechanism 3 is used to drive the loading mechanism 5 to move up and down. The lifting mechanism 3 is mounted on the fixed frame 1.

[0038] A drying and cleaning mechanism 4 is used to dry and clean the alumina powder inside the loading mechanism 5. The drying and cleaning mechanism 4 is installed on the fixed cylinder 2.

[0039] like Figure 1 and Figure 3 As shown, the lifting mechanism 3 includes two front-to-back symmetrical first electric telescopic rods 31 fixedly connected to the fixed frame 1. The top ends of the two first electric telescopic rods 31 are fixedly connected to a connecting horizontal plate 32. A connecting bracket 33 is fixedly connected at the middle position of the lower surface of the connecting horizontal plate 32. The connecting bracket 33 is coaxial with the fixed cylinder 2.

[0040] like Figure 3 As shown, the drying and cleaning mechanism 4 includes a heating unit 41 disposed on the outer circumferential surface of the fixed cylinder 2, an ultrasonic sound generating unit 42 disposed on the outer circumferential surface of the fixed cylinder 2 and below the heating unit 41, and an auxiliary component 43 disposed on the fixed cylinder 2 for auxiliary sealing during the drying and cleaning process of alumina powder. The interior of the fixed cylinder 2 is divided into upper and lower processing chambers corresponding to the heating unit 41 and the ultrasonic sound generating unit 42, which are the drying chamber and the cleaning chamber, respectively. The lower processing chamber on the outer circumferential surface of the fixed cylinder 2 is fixedly positioned and connected to a water inlet pipe.

[0041] like Figure 3 and Figure 4 As shown, the auxiliary component 43 includes a first upper sealing ring 431 fixedly connected to the top of the inner circumferential surface of the fixed cylinder 2, a second upper sealing ring 434 fixedly connected to the middle position of the inner circumferential surface of the fixed cylinder 2, an electromagnet connecting ring 432 fixedly connected to the bottom of the outer circumferential surface of the fixed cylinder 2, a baffle 433 snapped onto the lower surface of the electromagnet connecting ring 432, and a sealed arrangement between the electromagnet connecting ring 432 and the baffle 433. The baffle 433 itself is magnetic and attracts the electromagnet connecting ring 432.

[0042] like Figure 3 and Figure 4 As shown, the lower inner rings of the first upper sealing ring 431 and the second upper sealing ring 434 are both chamfered, and the upper circumferences of the first lower sealing plate 51 and the second lower sealing plate 53 are both chamfered. The chamfer positions of the first upper sealing ring 431 and the first lower sealing plate 51, and the second upper sealing ring 434 and the second lower sealing plate 53 are all matched and sealed.

[0043] In practical use, the first electric telescopic rod 31 is first retracted, and the first lower sealing plate 51 is moved downward through the connecting bracket 33 until the first lower sealing plate 51 is attached to the upper surface of the second upper sealing ring 434. Then the retraction of the first electric telescopic rod 31 is stopped. At this time, the electromagnet connecting ring 432 is de-energized, the electromagnet connecting ring 432 loses its magnetic force and no longer generates an attraction force on the baffle 433. The baffle 433 is then removed, and the loading of alumina powder begins.

[0044] like Figure 5 As shown, the loading mechanism 5 includes a first lower sealing plate 51 fixedly connected to the bottom end of the connecting bracket 33. A connector 52 is provided on the lower surface of the first lower sealing plate 51. A loading component 54 is provided on the connector 52. A second lower sealing plate 53 is fixedly connected to the bottom end of the loading component 54. Two left-right symmetrical pushing components 55 are provided on the loading component 54. A cleaning component 56 is provided on the loading component 54.

[0045] like Figure 6 As shown, the loading component 54 includes a connecting shaft 541 fixedly connected to the second lower sealing plate 53. A loading barrel 542 is rotatably connected to the circumferential surface of the connecting shaft 541. Multiple filter screens 544 arranged in a circumferential array are embedded and connected to the outer circumferential surface of the loading barrel 542. A sealing plate 543 can be detachably installed on the outer circumferential surface of the loading barrel 542 and between two filter screens 544. A second pulley 545 is fixedly connected to both outer end faces of the loading barrel 542.

[0046] In practical use, the second electric telescopic rod 523 is first extended to push the gantry connecting frame 521 to move the loading barrel 542 downward to below the bottom of the fixed cylinder 2. Then, the sealing plate 543 located on the top of the loading barrel 542 is removed from the loading barrel 542, and the alumina powder to be treated is put into the interior of the loading barrel 542. Then, the sealing plate 543 is reinstalled on the loading barrel 542. At this time, the second electric telescopic rod 523 is retracted to restore the loading barrel 542 to its original position. At the same time, the baffle 433 is snapped onto the electromagnet connecting ring 432, and the electromagnet connecting ring 432 is energized so that the electromagnet connecting ring 432 and the baffle 433 are attracted together. Then, the washing water is transported to the cleaning chamber through the water inlet pipe on the fixed cylinder 2, and then the cleaning of alumina powder begins.

[0047] When the cleaning of alumina powder begins, ultrasonic waves are first generated by the ultrasonic sound-generating unit 42, which, together with the washing water, clean the alumina powder. Then, the drive motor inside the portal frame 521 drives the first pulley 522 to rotate on the portal frame 521. The connecting shaft 541 rotates synchronously with the first pulley 522, causing the alumina powder inside the loading tank 542 to start rolling synchronously with the loading tank 542. This ensures that the alumina powder inside the loading tank 542 can fully contact the washing water, thus ensuring a better cleaning effect for the alumina powder.

[0048] like Figure 6 As shown, the connector 52 includes a portal frame 521 fixedly connected to the lower surface of the first lower sealing plate 51. The two vertical sections of the portal frame 521 are rotatably connected to the opposite surfaces of the two vertical sections. The lower surface of the first lower sealing plate 51 is fixedly connected to two symmetrical second electric telescopic rods 523. The telescopic ends of the second electric telescopic rods 523 are fixedly connected to the vertical sections of the portal frame 521. The upper surface of the first lower sealing plate 51 is provided with an air extraction connection pipe.

[0049] like Figure 6As shown, a bidirectional drive motor (not shown in the figure) is installed inside the horizontal section of the portal frame 521. The bidirectional drive motor is connected to the first pulley 522 via belt drive (not shown in the figure). The first pulley 522 is connected to the second pulley 545 via belt drive. The second pulley 545 is coaxial with the connecting shaft 541 and the loading bucket 542.

[0050] like Figure 7 and Figure 8 As shown, taking the pusher 55 on the left as an example, the pusher 55 includes an adjusting ring 551 fixedly connected to the inner end face of the loading barrel 542 and a limiting groove 555 opened on the circumferential surface of the connecting shaft 541. An mounting ring 554 is slidably connected to the circumferential surface of the connecting shaft 541. The mounting ring 554 is elastically slidably connected to the limiting groove 555. An mounting seat 553 is fixedly connected to the circumferential surface of the mounting ring 554. A push rod 552 is fixedly connected to the left side of the mounting seat 553. The side of the adjusting ring 551 near the push rod 552 is set with a wavy curved surface. The left end of the push rod 552 is slidably engaged with the adjusting ring 551 on the left side. The adjusting ring 551 is coaxial with the loading barrel 542.

[0051] In practical use, after the alumina powder cleaning is completed, the electromagnet connecting ring 432 is de-energized, releasing the attraction force on the baffle 433. The baffle 433 is then removed from the electromagnet connecting ring 432, draining the washing water from the cleaning chamber. Simultaneously, the first electric telescopic rod 31 extends, causing the first lower sealing plate 51 to move upward. When the first lower sealing plate 51 comes into contact with the first upper sealing ring 431, the first electric telescopic rod 31 stops retracting, maintaining the tension on the first lower sealing plate 51, thus ensuring the first lower sealing... Plate 51 is tightly attached to the first upper sealing ring 431, and at the same time, the second lower sealing plate 53 is also tightly attached to the second upper sealing ring 434. At this time, the drying chamber forms a sealed space. Then, the drying chamber is evacuated by connecting the external vacuum equipment to the vacuum connection pipe on the first lower sealing plate 51. When the drying chamber is in a vacuum state, the heating unit 41 starts to work and heats up the inside of the drying chamber to start drying the alumina powder. Similarly, the loading bucket 542 rotates so that the alumina powder can be fully dried.

[0052] During the drying process, the adjusting ring 551 rotates synchronously with the loading drum 542. At this time, the adjusting ring 551 is in contact with the push rod 552. When the crest of the adjusting ring 551 contacts the push rod 552, the adjusting ring 551 generates a thrust on the push rod 552, pushing the mounting ring 554 to move away from the adjusting ring 551 on the connecting shaft 541. When the contact position between the adjusting ring 551 and the push rod 552 moves from the crest to the trough, the adjusting ring 551 no longer generates a thrust on the push rod 552. Since the mounting ring 554 and the limiting slide groove 555 are elastically slidably connected, under the action of the elastic force, the mounting ring 554 is driven to return to its original position on the loading drum 542. As the adjusting ring 551 continues to rotate, the crest and trough positions of the adjusting ring 551 alternately contact the push rod 552, thereby realizing the reciprocating sliding of the mounting ring 554 on the connecting shaft 541.

[0053] like Figure 7 and Figure 8 As shown, the cleaning component 56 includes two left-right symmetrical second connecting rods 563 fixedly connected to the circumferential surface of the connecting shaft 541. The bottom ends of the two second connecting rods 563 are fixedly connected to a fixed cleaning brush plate 564. The lower surface of the mounting ring 554 is fixedly connected to a first connecting rod 562. The bottom end of the first connecting rod 562 is fixedly connected to a sliding cleaning brush plate 565. The upper surface of the sliding cleaning brush plate 565 is fixedly connected to an elastic telescopic connecting rod 561. One end of the elastic telescopic connecting rod 561 away from the center of the sliding cleaning brush plate 565 is fixedly connected to the second connecting rod 563. The sliding cleaning brush plate 565 is slidably connected to the fixed cleaning brush plate 564.

[0054] In practical use, during the drying process, when the mounting ring 554 slides back and forth on the connecting shaft 541, the mounting ring 554 drives the sliding cleaning brush 565 to slide synchronously through the first connecting rod 562. During the sliding process, the elastic force of the elastic telescopic connecting rod 561 allows the sliding cleaning brush 565 to return to its original position smoothly. At the same time, during the rotation of the loading tank 542, the fixed cleaning brush 564 and the sliding cleaning brush 565 can clean the alumina powder attached to the filter screen 544 to ensure that the filter screen 544 has sufficient water flow. In addition, the setting of the sliding cleaning brush 565 and the fixed cleaning brush 564 can generate a turbulence effect on the alumina powder as the loading tank 542 rolls, so that the alumina powder can be more dispersed inside the loading tank 542. Combined with the ultrasonic waves generated by the ultrasonic sound generating unit 42, the alumina powder can be dried more thoroughly, improving the drying efficiency of the alumina powder.

[0055] After drying is complete, the loading barrel 542 is returned to its original position. The second electric telescopic rod 523 is then extended to push the loading barrel 542 downwards until it is below the bottom of the fixed cylinder 2. The bottom sealing plate 543 is then opened to release the alumina powder. The sealing plate 543 is then reinstalled on the loading barrel 542. The second electric telescopic rod 523 is then retracted to return the loading barrel 542 to its original position. At the same time, the baffle 433 is re-clamped onto the electromagnet connecting ring 432, and the electromagnet connecting ring 432 is energized to generate an adsorption force on the baffle 433. The above steps are then repeated for the next drying and cleaning of the alumina powder.

[0056] Working principle: In actual use, firstly, open the sealing plate 543 located at the top, and put the alumina powder into the loading tank 542. Then, fix the sealing plate 543 back onto the loading tank 542. Then, wash water is introduced into the cleaning chamber through the water inlet pipe on the fixed cylinder 2. Then, the ultrasonic sound generating unit 42 starts working, and the ultrasonic waves begin to clean the alumina powder inside the loading tank 542. At the same time, the connecting piece 52 drives the loading tank 542 to rotate, so that the alumina powder inside the loading tank 542 is washed away. As the loading tank 542 rotates, it can make more thorough contact with the washing water. At the same time, during the rotation of the loading tank 542, the sliding cleaning brush 565 is pushed by the pusher 55 to slide, cleaning the alumina powder attached to the filter screen 544, so as to ensure that the washing water can pass through the interior of the loading tank 542 more smoothly. After the cleaning work is completed and the drying is finished, the electromagnet connecting ring 432 is de-energized. At this time, the electromagnet connecting ring 432 is no longer magnetic, the baffle 433 separates from the electromagnet connecting ring 432, and the detergent inside the cleaning chamber is released.

[0057] At this time, the lifting mechanism 3 drives the loading bucket 542 to move upward to the position of the drying chamber. The first lower sealing plate 51 and the second lower sealing plate 53 cooperate with the first upper sealing ring 431 and the second upper sealing ring 434 to form a sealed space in the drying chamber. At this time, the external vacuum equipment is connected to the vacuum connection pipe on the first lower sealing plate 51 to evacuate the drying chamber. When the inside of the drying chamber is in a vacuum state, the heating unit 41 starts to work to heat up the inside of the drying chamber and begin to dry the alumina powder. Similarly, the loading bucket 542 rotates so that the alumina powder can be fully dried.

[0058] After drying is complete, the loading barrel 542 is returned to its original position. At the same time, the second electric telescopic rod 523 extends and pushes the loading barrel 542 to continue moving downwards, so that the loading barrel 542 moves to below the bottom of the fixed cylinder 2. Then, the bottom sealing plate 543 is opened to release the alumina powder. After that, the sealing plate 543 is reinstalled on the loading barrel 542. Then, the second electric telescopic rod 523 retracts to return the loading barrel 542 to its original position. At the same time, the baffle 433 is re-clamped onto the electromagnet connecting ring 432, and the electromagnet connecting ring 432 is energized to generate an adsorption force on the baffle 433. Then, the above steps are repeated to carry out the next drying and cleaning of alumina powder.
