[0033] The utility model will be further described in detail in combination with the drawings.

[0034] Please refer to Figures 1-7 As shown in the figure, in the embodiment, a kind of carbon additive particle size screening device is provided, including device body 1, its upper and lower ends are equipped with feed inlet 3 and discharge outlet 4, sieve plate 7 is movably arranged in device body 1, mounting block 13 is fixedly connected in device body 1, vibration motor 14 for driving sieve plate 7 to vibrate is fixedly connected in mounting block 13, a plurality of sieve holes 8 are penetrated on sieve plate 7, a groove 17 is penetrated on sieve plate 7, access hole 6 is penetrated on device body 1 relative to groove 17, mounting plate 5 is detachably connected on access hole 6, adjusting plate 11, which is movably arranged in groove 17, is penetrated with communication groove 20 in sieve hole 8, inclined block 18 is fixedly connected on adjusting plate 11 in communication groove 20, inclined block 18 has the inclined surface inclined from top to bottom, and the inclined surface of inclined block 18 is attached to both ends of sieve hole 8.

[0035] Specifically, the recarburizer enters the device body 1 from the feed port 3 and falls on the sieve plate 7. The vibrating motor 14 starts to work to make the sieve plate 7 vibrate. During the vibration process, the recarburizer continuously jumps and rolls on the sieve plate 7 and gradually moves to the sieve hole 8. Since there are multiple sieve holes 8 on the sieve plate 7, the recarburizer with smaller particle size can fall through the sieve hole 8 and finally be discharged from the discharge port 4 of the device body 1, realizing the preliminary separation from the recarburizer with larger particle size. The groove 17 on the sieve plate 7 corresponds to the maintenance opening 6 on the device body 1. When the sieve plate 7 needs to be maintained, cleaned or replaced, the mounting plate 5 on the maintenance opening 6 can be opened. The adjusting plate 11 is pulled back and forth to make the adjusting plate 11 move inside the groove 17. When the adjusting plate 11 moves, the inclined block 18 moves inside the groove 17, thereby changing the diameter of the sieve hole 8, making the recarburizer blocked in the sieve hole 8 fall off, achieving the purpose of cleaning. Of course, the inclined block 18 is located in the sieve hole 8 in the initial state and is connected with the sieve hole 8. The arrangement of the inclined block 18 makes the recarburizer have a slanting movement track when passing through the communication groove 20 and entering the sieve hole 8, instead of directly falling vertically through the sieve hole 8. In this way, the recarburizer will be subjected to certain resistance and guiding effect when passing through the sieve hole 8, avoiding the incomplete or uneven sieving phenomenon caused by the direct and rapid passing of the recarburizer through the sieve hole 8, facilitating the subsequent cleaning of the sieve hole 8, simplifying the overall operation, facilitating the daily inspection, maintenance and cleaning work of the sieve plate 7, reducing the possibility of the recarburizer blocking the sieve hole 8, facilitating the cleaning of the recarburizer at the sieve hole 8, reducing the wear and tear, saving the cost.

[0036] In this embodiment, as shown in Figure 4 , Figure 5 and Figure 7 , the groove 17 of the sieve plate 7 movably has an extrusion assembly 9 relative to the inclined block 18. The extrusion assembly 9 includes a movable plate 93 movably arranged on the sieve plate 7. The sieve plate 7 is provided with a movable groove 94 in which the movable plate 93 moves. The movable groove 94 and the groove 17 are communicatively arranged. A connecting plate 92 is fixedly connected with one end of the movable plate 93 opposite to the inclined block 18. A rotating roller 91 is rotatably connected with one end of the connecting plate 92 away from the movable plate 93. The rotating roller 91 is arranged at the upper and lower ends of the sieve hole 8. A spring 95 is located in the movable groove 94. The two ends of the spring 95 are fixedly connected with the sieve plate 7 at the end of the movable groove 94 and the movable plate 93, respectively. Specifically, the rotating roller 91 plays a guiding role in the movement of the recarburizer in the moving degree. Meanwhile, the rotating roller 91 can also shield the connecting groove. When the inclined block 18 cleans the recarburizer at the sieve hole 8 by driving the adjusting plate 11, the inclined block 18 extrudes the recarburizer, so that the recarburizer extrudes the rotating roller 91. The rotating roller 91 drives the movable plate 93 to extrude the spring 95 through the connecting plate 92, thereby further improving the cleaning effect of the recarburizer at the sieve hole 8 and avoiding the blocking phenomenon.

[0037] In the embodiment, as shown in Figure 7 The length of the communication groove 20 is greater than the length of the sieve hole 8, and the extrusion assembly 9 is located in the communication groove 20.

[0038] In the embodiment, as shown in Figure 4 、 Figure 5 and Figure 6 A plurality of positioning holes 19 are provided through the adjusting plate 11, and the plurality of positioning holes 19 are arranged at intervals along the extension direction of the groove body 17. The sieve plate 7 is provided with a positioning bolt 16 for limiting the plurality of positioning holes 19. Specifically, by providing a plurality of positioning holes 19 on the adjusting plate 11, the relative position of the adjusting plate 11 in the groove body 17 can be changed by cooperating the positioning bolt 16 with the positioning holes 19 at different positions, so as to change the relative position relationship between the communication groove 20 and the sieve hole 8, and adjust the effective area of the screening and the screening accuracy.

[0039] In the embodiment, as shown in Figure 4 The adjusting plate 11 is embedded with a plurality of adjusting grooves 12. Specifically, the adjusting grooves 12 facilitate the operation of the adjusting plate 11.

[0040] In the embodiment, as shown in Figure 2 and Figure 3 The sieve plate 7 is fixedly connected with a plurality of sliding blocks 10, and the device body 1 is provided with a sliding groove 15 for sliding the sliding blocks 10. The sliding groove 15 extends along the direction from the feeding port 3 to the discharging port 4 of the device body 1.

[0041] In the embodiment, as shown in Figure 1 and Figure 3 The mounting block 13 is an inverted triangular structure, and the device body 1 is fixedly connected with a perspective plate 2. Specifically, the inverted triangular structure of the mounting block 13 can better fix the vibration motor 14, effectively transmit the vibration of the vibration motor 14 to the sieve plate 7, and the perspective plate 2 facilitates the operator to observe the screening situation of the material in the device body 1, such as the distribution of the material and the working state of the sieve plate 7.

[0042] Working principle:

[0043] After the recarburizer enters the feeding port 3 of the device body 1, it will fall on the sieve plate 7, and the vibration motor 14 starts to work to make the sieve plate 7 vibrate. During the vibration process, the recarburizer continuously jumps and rolls on the sieve plate 7 and gradually moves to the sieve hole 8. Since there are multiple sieve holes 8 on the sieve plate 7, the recarburizer with smaller particle size can fall through the sieve hole 8 and finally be discharged from the discharge port 4 of the device body 1, realizing the preliminary separation from the recarburizer with larger particle size. The groove 17 on the sieve plate 7 corresponds to the maintenance opening 6 on the device body 1. When the sieve plate 7 needs to be maintained, cleaned or replaced, the mounting plate 5 on the maintenance opening 6 can be opened, and the adjusting plate 11 can be moved in the groove 17 by reciprocating pulling, so that the adjusting plate 11 can move in the groove 17. When the adjusting plate 11 moves, the inclined block 18 moves in the groove 17, thereby changing the diameter of the sieve hole 8, so that the recarburizer blocked in the sieve hole 8 falls off to achieve the purpose of cleaning. Of course, the inclined block 18 is located in the sieve hole 8 in the initial state and is connected with the sieve hole 8. The arrangement of the inclined block 18 makes the recarburizer have a slanting movement track when passing through the communication groove 20 and entering the sieve hole 8, instead of directly falling vertically through the sieve hole 8. In this way, the recarburizer will be subjected to certain resistance and guiding effect when passing through the sieve hole 8, avoiding the incomplete or uneven sieving phenomenon caused by the direct and rapid passing of the recarburizer through the sieve hole 8, and facilitating the subsequent cleaning of the sieve hole 8. In addition, the moving degree of the rotating roller 91 plays a guiding role in the movement of the recarburizer, and can also shield the connecting groove. When the inclined block 18 cleans the recarburizer at the sieve hole 8 by driving the adjusting plate 11, the inclined block 18 extrudes the recarburizer, so that the recarburizer extrudes the rotating roller 91. The rotating roller 91 drives the movable plate 93 to extrude the spring 95 through the connecting plate 92, thereby further improving the cleaning effect of the recarburizer at the sieve hole 8 and avoiding the blocking phenomenon. The whole operation is simple, which facilitates the daily inspection, maintenance and cleaning work of the sieve plate 7, reduces the possibility of recarburizer blocking the sieve hole 8, facilitates the cleaning of the recarburizer at the sieve hole 8, reduces the wear and tear, and saves the cost.
