Description

Technical Field

[0001] This application relates to the technical field of ultrasonic vibrating screens, and in particular to a feeding device for an ultrasonic vibrating screen. Background Technology

[0002] An ultrasonic vibrating screen converts 220V, 50HZ or 110V, 60HZ electrical energy into 38KHZ high-frequency electrical energy, which is then input into an ultrasonic transducer to generate 38KHZ mechanical vibration, thereby achieving efficient screening and screen cleaning.

[0003] Currently, Chinese patent CN218475577U discloses an ultrasonic vibrating screen device including a feed pipe, an ultrasonic vibrating screen, a first powder flow meter, a feeding butterfly valve, a second powder flow meter, and an output material buffer bin. The ultrasonic vibrating screen includes a dust cover and a middle frame assembly. The middle frame assembly forms a screening chamber and a discharge port. The dust cover is located on the screening chamber and has an inlet. The screening chamber is connected to both the inlet and the discharge port. One end of the first powder flow meter is connected to the inlet, and the feeding butterfly valve is connected to both the feed pipe and the other end of the first powder flow meter. One end of the second powder flow meter is connected to the discharge port, and the output material buffer bin is connected to the other end of the second powder flow meter.

[0004] When powder enters the feed inlet of the ultrasonic vibrating screen directly through the first receiving hose, it can cause blockage at the feed inlet, preventing the ultrasonic vibrating screen from effectively screening the powder. In this case, the operator needs to stop the ultrasonic vibrating screen, then disconnect the first receiving hose from the feed inlet, clear the blockage, and finally reconnect the first receiving hose to the feed inlet of the ultrasonic vibrating screen. This operation takes time, thus increasing the overall screening time and reducing efficiency. Utility Model Content

[0005] To ensure efficiency, this application provides a feeding device for an ultrasonic vibrating screen.

Connecting pipes communicating with the transfer cavity are provided at both ends of the transfer block. The transmission pipe is disposed on the connecting pipe via the connector. One transmission pipe is connected to the powder bin, and the other transmission pipe is connected to an ultrasonic vibrating screen for screening powder.

[0008] By adopting the above technical solution, the powder in the powder bin enters the connecting pipe through a transmission pipe and then enters the transfer chamber of the transfer block. The vibration component is activated, which drives the transfer block to vibrate, causing the powder that is stuck together to separate and move within the transfer chamber. The powder in the transfer chamber enters the ultrasonic vibrating screen for sieving through another connecting pipe and a conveying pipe.

[0018] By adopting the above technical solution, when the rotating block is located in the rotating groove, the end of the connecting shaft away from the rotating block and the first positioning block will pass through the first through hole; then the sliding block is moved, and the sliding block drives the second positioning block to move towards the first positioning block, so that one side of the second positioning block abuts against the first positioning block; then the rotating block can be located in the rotating groove.

[0038] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0039] This application discloses a feeding device for an ultrasonic vibrating screen.

[0040] refer to Figure 1 A feeding device for an ultrasonic vibrating screen includes a support frame 1 bolted to one side of the ultrasonic vibrating screen, a powder bin 2 mounted on the support frame 1, and a transfer mechanism 3 mounted on the support frame 1, the transfer mechanism 3 connecting the powder bin 2 and the ultrasonic vibrating screen.

A first horizontal block 11 and a second horizontal block 12 are fixedly connected to the support rod 13 in its vertical direction. The first horizontal block 11 is located above the second horizontal block 12. The powder hopper 2 is fixed on the first horizontal block 11. The transfer mechanism 3 is disposed on the second horizontal block 12.

[0042] refer to Figure 1 and Figure 2The transfer mechanism 3 includes a vibration component 32, which includes a vibrator 321. The vibrator 321 is provided with a mounting bolt 323, which passes through the vibrator 321 and is connected to the second horizontal block 12. A vibration block 322 is provided at the end of the vibrator 321 away from the second horizontal block 12, and a transfer block 31 is provided on the vibration block 322.

The vibrator 321 abuts against the adjustment plate 42, and the mounting bolt 323 passes through the vibrator 321 and is threadedly connected to the adjustment plate 42.

[0044] refer to Figure 4 and Figure 5 A fixing component 43 is provided at the end of the rotating block 41 away from the adjusting plate 42. The fixing component 43 includes a connecting shaft 431 fixedly connected to the rotating block 41. When the rotating block 41 is located in the rotating groove, the end of the connecting shaft 431 away from the rotating block 41 passes through the first through hole on the second horizontal block 12. A slot is provided at the end of the connecting shaft 431 away from the rotating block 41, and a fixing block 432 is engaged in the slot. A first fixing bolt 433 is provided on the connecting shaft 431. The first fixing bolt 433 passes through the connecting shaft 431 and is threadedly connected to the fixing block 432 located in the slot. A second fixing bolt 434 is provided at the end of the fixing block 432 away from the connecting shaft 431. The second fixing bolt 434 passes through the fixing block 432 and is threadedly connected to the second horizontal block 12.

[0045] First, place the rotating block 41 into the rotating groove of the second horizontal block 12, and place the end of the connecting shaft 431 away from the rotating block 41 through the first through hole and below the second horizontal block 12; then, engage one end of the fixing block 432 with the slot on the connecting shaft 431, and then thread the first fixing bolt 433 through the connecting shaft 431 to the fixing block 432 located in the slot; finally, thread the second fixing bolt 434 through the fixing block 432 to the second horizontal block 12.

[0046] refer to Figure 4 and Figure 5 To reduce the likelihood of the rotating block 41 dislodging from the rotating groove and to ensure it remains within the groove, a limiting mechanism 6 is provided on the rotating block 41. An adjustment cavity is formed within the rotating block 41, and an annular placement groove 411 is formed on its side wall. Two sliding holes are formed on the rotating block 41, connecting the placement groove 411 and the adjustment cavity. An annular limiting groove 121 is formed on the second horizontal block 12, and the rotating groove is connected within the limiting groove 121.

[0047] The limiting mechanism 6 includes two limiting blocks 61, both of which can be located within the placement groove 411, and a portion of each limiting block 61 can also enter the limiting groove 121, and each limiting block 61 can rotate within the limiting groove 121. An adjusting assembly 62 is provided on the rotating block 41, including an adjusting shaft 621 rotatably connected to the rotating block 41. One end of the adjusting shaft 621 is located within the adjusting cavity, and the end face of the other end coincides with the end face of the rotating block 41 away from the connecting shaft 431. An adjusting gear 622 is keyed to the adjusting shaft 621 located within the adjusting cavity. An adjusting rack 623 is fixedly connected to each of the two limiting blocks 61, with the adjusting gear 622 located between the two adjusting racks 623, and both adjusting racks 623 meshing with the adjusting gear 622. A countersunk hole is provided at the end of the adjusting shaft 621 away from the adjusting gear 622.

[0048] Initially, both limiting blocks 61 are located in the placement groove 411 of the rotating block 41. When the rotating block 41 is located in the rotating groove, and the end face of the rotating block 41 away from the connecting shaft 431 coincides with the end face of the second horizontal block 12 near the first horizontal block 11, the Allen wrench engages with the countersunk hole on the adjusting shaft 621. Rotating the Allen wrench causes the adjusting shaft 621 to rotate, which in turn causes the adjusting gear 622 to rotate. The adjusting gear 622 causes the two adjusting racks 623 to move in opposite directions, and the two adjusting racks 623 cause the limiting block 61 to move in opposite directions, so that the end of the limiting block 61 away from the adjusting rack 623 is located in the limiting groove 121 of the second horizontal block 12, while the end near the adjusting shaft 621 remains located in the placement groove 411 of the rotating block 41. At this time, the end face of the rotating block 41 away from the connecting shaft 431 coincides with the end face of the second horizontal block 12 near the first horizontal block 11, and the adjusting plate 42 abuts against the second horizontal block 12.

[0049] refer to Figure 4 and Figure 5 In order for the timing limit block 61 to be aligned with the limiting groove 121, a positioning mechanism 5 connected to the connecting shaft 431 is provided on the second horizontal block 12. The positioning mechanism 5 includes a first positioning block 51 fixedly connected to the connecting shaft 431. The first positioning block 51 is located between the rotating block 41 and the slot. When the rotating block 41 is completely located in the rotating groove, the first positioning block 51 passes through the first through hole on the second horizontal block 12 and is a certain distance away from the side of the second horizontal block 12 away from the first horizontal block 11. A sliding groove is provided on the side of the second horizontal block 12 away from the first horizontal block 11. A sliding block 53 is slidably connected in the sliding groove. A second positioning block 52 is fixedly connected on the sliding block 53. One side of the second positioning block 52 can abut against the first positioning block 51 and the other end can abut against the second horizontal block 12.

[0050] When the connecting shaft 431 moves away from the rotating block 41 and the first positioning block 51 both pass through the first through hole on the second horizontal block 12, the sliding block 53 moves towards the connecting shaft 431. The sliding block 53 drives the second positioning block 52 to move towards the connecting shaft 431, so that one side of the second positioning block 52 abuts against the second horizontal block 12 and the other end abuts against the first positioning block 51. At this time, the rotating block 41 will be completely located in the rotating groove, that is, the end face of the rotating block 41 away from the connecting shaft 431 coincides with the end face of the second horizontal block 12 near the first horizontal block 11. Then, the fixing block 432 is connected to the fixing block 432 by the first fixing bolt 433, and the fixing block 432 is connected to the second fixing block 432 by the second bolt. Finally, the second positioning block 52 and the sliding block 53 are moved so that the second positioning block 52 no longer abuts against the first positioning block 51.

[0051] refer to Figure 1 and Figure 6 In order to ensure that the wire of the vibrator 321 is positioned on the support rod 13 in an adjustable manner, a limiting mechanism 7 is provided on the support rod 13. The limiting mechanism 7 includes a limiting block 71 that abuts against the support rod 13. A limiting groove 711 is provided on the limiting block 71, and the wire of the vibrator 321 is located in the limiting groove 711. A limiting bolt 72 is provided on the limiting block 71, and the limiting bolt 72 passes through the limiting block 71 and is threadedly connected to the support rod 13.

[0052] refer to Figure 2 To allow the vibrator 321's lead wires to be adjusted and positioned on the second horizontal block 12, a protective support assembly is provided on the second horizontal block 12. The second horizontal block 12 has two second through holes 122, and a rotating groove is located between the two second through holes 122. The protective support assembly includes a protective support sleeve 8, the portion of which, corresponding to the second through holes 122, bypasses the second through holes 122 and wraps around the second horizontal block 12. A fixing element, which in this embodiment is adhesive tape, is provided on the protective support sleeve 8, wrapping around it and fixing the protective support sleeve 8 to the second horizontal block 12. The portion of the protective support sleeve 8 corresponding to the rotating groove has a notch 81 for easy adjustment of the lead wires on the vibrator 321 by the operator.

[0053] refer to Figure 2 and Figure 7 The transfer block 31 has an inclined transfer cavity 311, and the relative height of the rotating block 41 near the ultrasonic vibrating screen is lower than the relative height of the side away from the ultrasonic vibrating screen.

[0054] Both ends of the transfer block 31 are fixedly connected to connecting pipes 33 that communicate with the transfer cavity 311. Each connecting pipe 33 is connected to a transmission pipe 34 made of soft material, which can be made of cloth. A connector 35 is provided on the transmission pipe 34 to fix the transmission pipe 34 to the connecting pipe 33. The connector 35 can be a hose clamp or a clamp. The end of the transmission pipe 34 closest to the ultrasonic vibrating screen and furthest from the transfer block 31 is connected to the inlet of the ultrasonic vibrating screen, and the end of the transmission pipe 34 furthest from the ultrasonic vibrating screen and furthest from the transfer block 31 is connected to the outlet of the powder hopper 2.

[0055] The implementation principle of the feeding device of the ultrasonic vibrating screen according to the embodiments of this application is as follows: First, the rotating block 41 is installed into the rotating groove of the second horizontal block 12, and the first positioning block 51 and the connecting shaft 431 are made to pass through the first through hole on the second horizontal block 12 at the end away from the rotating block 41; then, the sliding block 53 and the second positioning block 52 are moved so that one side of the second positioning block 52 abuts against the first positioning block 51 and the other end abuts against the second horizontal block 12. At this time, the rotating block 41 will be better positioned in the rotating groove of the second horizontal block 12, and the end face of the rotating block 41 away from the connecting shaft 431 coincides with the end face of the second horizontal block 12 near the first horizontal block 11, and the adjusting plate 42 abuts against the second horizontal block 12. Then, the adjusting shaft 621 is rotated so that a part of the limiting block 61 is located in the limiting groove 121 of the second horizontal block 12. Then, one end of the fixing block 432 is engaged with the slot on the connecting shaft 431, and the first fixing bolt 433 is threaded through the connecting shaft 431 and connected to the fixing block 432.

[0056] Then, the vibrator 321 with the intermediate block 31 is brought into contact with the adjusting plate 42. Next, the mounting bolt 323 is threaded through the vibrator 321 and connected to the adjusting plate 42 to fix the vibrator 321 on the adjusting plate 42.

[0057] Next, adjust the positions of the transfer block 31 and the vibrator 321 relative to the ultrasonic vibrating screen. After the position of the transfer block 31 is adjusted, the second fixing bolt 434 passes through the fixing block 432 and is threadedly connected to the second horizontal block 12. Then, wrap the protective support sleeve 8 around the conductor of the vibrator 321 corresponding to the position of the second through hole 122, and then fix the protective support sleeve 8 to the second horizontal block 12 with tape. Next, straighten the conductor of the vibrator 321, so that the limiting block 71 abuts against the support rod 13, and the vibrating conductor is located in the limiting groove 711 of the limiting block 71. Then, thread the limiting bolt 72 through the limiting block 71 and connect it to the support rod 13.

[0058] Finally, the transmission pipe 34 is connected to the connecting pipe 33 via the connector 35, so that one of the transmission pipes 34 is connected to the ultrasonic vibrating screen and the other transmission pipe 34 is connected to the powder hopper 2.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
