Description

Technical Field

[0001] This utility model relates to the field of screening device technology, specifically an activated carbon particle screening device. Background Technology

[0002] Activated carbon particle screening is a crucial step in the activated carbon production process. Screening removes substandard particles, ensuring the product meets particle size standards. Different particle sizes of activated carbon sieves are suitable for various applications, allowing for the separation of different product requirements. Vibrating screens are typically used for screening activated carbon particles. By tilting the vibrating motor, the activated carbon particles gradually move forward on the screening plate, separating particles of different sizes. However, the screening plate angle is usually fixed. While a horizontally set screening plate offers relatively high efficiency, the screening effect is relatively poor. When there are many small-diameter activated carbon particles, making screening difficult, incomplete screening may occur, hindering successful screening of the activated carbon particles. Utility Model Content

[0003] The purpose of this invention is to provide an activated carbon particle screening device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An activated carbon granule screening device includes a screening frame with a support mechanism at its bottom. An installation frame is fixedly connected to the bottom surface of the screening frame, and two vibration motors are fixedly connected to the installation frame. The vibration motors are inclinedly mounted on the installation frame. A screening plate one and a screening plate two are disposed inside the screening frame. Two discharge frames are fixedly connected to the screening frame, corresponding to the top and bottom of the screening plate two, respectively. The screening plate one is inclined, and the inclination angle of the vibration motors is greater than the inclination angle of the screening plate one. Two connecting seats are fixedly connected to the screening plate one, and a limiting seat is fixedly connected to the screening plate two. A screw passing through the two connecting seats is disposed inside the limiting seat, and a nut is screwed onto the end of the screw.

[0006] Furthermore, the support mechanism includes a support frame, four support springs, and four fixed seats;

[0007] The support frame is located at the bottom of the screening frame;

[0008] All four support springs are fixedly connected to the top of the support frame;

[0009] Four fixed seats are fixedly connected to four support springs respectively. The screening frame is fixedly connected to the four fixed seats, and the bottom of the fixed seat is fixedly connected to the top of the adjacent support spring.

[0010] Furthermore, the first screening plate is provided with an arc-shaped groove, and the second screening plate is fixedly connected with a pad that is slidably connected to the arc-shaped groove. The pad is arc-shaped, and the axes of the arc-shaped groove and the pad are both coincident with the axis of the screw.

[0011] Furthermore, the screening plate 2 is fixedly connected to two L-shaped plates, and the top of the L-shaped plates is provided with several fixing bolts. The top of the L-shaped plates is attached to the top surface of the screening frame, and the fixing bolts pass through the top of the L-shaped plates and the top of the screening frame.

[0012] Preferably, an arc-shaped plate that is slidably connected to the screening plate is fixedly connected inside the screening frame.

[0013] Furthermore, the top of the screening frame is fixedly connected to two fixing plates, and the top of the screening plate is fixedly connected to two positioning plates. Both the fixing plates and the positioning plates are provided with several round holes, and the positioning plates are provided with several positioning bolts, which pass through the round holes on the corresponding positioning plates and fixing plates.

[0014] Furthermore, the arc-shaped plate is fixedly connected to a filling block that is slidably connected to the adjacent positioning plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The screening frame is equipped with a screening plate 1 and a screening plate 2. The screw can rotate screening plate 1 onto screening plate 2. When there are many small-diameter activated carbon particles and the screening is relatively difficult, screening plate 1 can be rotated downwards as needed to increase its tilt angle. During the vibrating screening process, the activated carbon particles move at a relatively slow speed on screening plate 1, allowing screening plate 1 to screen the activated carbon particles more thoroughly. After screening by screening plate 1, the activated carbon particles move to screening plate 2. At this time, the number of small-diameter activated carbon particles is relatively small. Screen plate 2 is horizontally set, so the remaining activated carbon particles can be screened normally through screening plate 2. This is beneficial for accommodating activated carbon particles with different screening difficulties, ensuring thorough screening of activated carbon particles, and maximizing the efficiency of activated carbon particle screening.

[0024] 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.

[0025] Please see Figure 1-6In this embodiment of the present invention, an activated carbon granule screening device includes a screening frame 10, a support mechanism 20 at the bottom of the screening frame 10, an installation frame 50 fixedly connected to the bottom surface of the screening frame 10, two vibration motors 51 fixedly connected to the installation frame 50, the vibration motors 51 being inclinedly mounted on the installation frame 50, a screening plate 30 and a screening plate 40 being provided inside the screening frame 10, and two discharge frames 11 fixedly connected to the screening frame 10, the two discharge frames 11 corresponding to the top and bottom of the screening plate 40 respectively, the screening plate 30 being inclined, the inclination angle of the vibration motors 51 being greater than the inclination angle of the screening plate 30, two connecting seats 34 fixedly connected to the screening plate 30, and a limiting seat 44 fixedly connected to the screening plate 40. Inside the seat 44, there is a screw 70 that passes through the interior of two connecting seats 34. The end of the screw 70 is screwed with a nut. The screw 70 has threads at its end. The large end of the screw 70 abuts against one connecting seat 34, and the end of the nut abuts against the other connecting seat 34. The screw 70 is thus fixed to the two connecting seats 34 by the nut. After the screw 70 passes through the interior of the limiting seat 44, the connecting seat 34 can be rotated and set on the limiting seat 44 by the screw 70. The screening plate 10 is then rotated and set on the screening plate 2 40. The length of the screw 70 is less than the width of the screening plate 1 30. Inside the screening frame 10, there is an arc-shaped plate 13 that is slidably connected to the screening plate 1 30. The arc-shaped plate 13 can block the end of the screening plate 1 30.

[0026] Specifically, when there are many small-diameter activated carbon particles and the screening is relatively difficult, the screening plate 30 can be rotated downwards as needed to increase its tilt angle. This allows the activated carbon particles to be conveyed to the side of the top surface of the screening plate 30 away from the screening plate 40. Then, the vibration motor 51 is started, causing the screening frame 10 to vibrate continuously, thus vibrating and screening the activated carbon particles. The activated carbon particles move relatively slowly on the screening plate 30, allowing for more thorough screening. After the activated carbon particles have been screened by the screening plate 30 and moved to the screening plate 40, the number of small-diameter activated carbon particles is relatively small. Since the screening plate 40 is set horizontally, the remaining activated carbon particles can be screened normally through the screening plate 40. This method is beneficial for accommodating activated carbon particles with different screening difficulties, ensuring thorough screening of activated carbon particles, and maximizing the efficiency of activated carbon particle screening.

[0027] During screening, large-diameter activated carbon particles can enter the top discharge frame 11 and then exit from the end of the top discharge frame 11. Small-diameter activated carbon particles that pass through the screening plate 30 and the screening plate 40 can fall onto the inner bottom surface of the screening frame 10 and then gradually move towards the bottom discharge frame 11. After entering the bottom discharge frame 11, they can exit from the end of the bottom discharge frame 11. Both discharge frames 11 are triangular, and the discharge ends of the two discharge frames 11 are staggered.

[0028] Example 1

[0029] like Figure 1 and Figure 2 As shown, in this embodiment, the support mechanism 20 includes a support frame 21, four support springs 22, and four fixed seats 23;

[0030] The support frame 21 is set at the bottom of the screening frame 10. Four support springs 22 are fixedly connected to the top of the support frame 21. Four fixed seats 23 are fixedly connected to the four support springs 22 respectively. The screening frame 10 is fixedly connected to the four fixed seats 23. The bottom of the fixed seat 23 is fixedly connected to the top of the adjacent support spring 22.

[0031] In practice, the support frame 21 can support the fixed seat 23 through the support spring 22, and then support the screening frame 10. When the vibration motor 51 is started, the screening frame 10 will drive the fixed seat 23 to vibrate on the support spring 22, thereby smoothly vibrating and screening the activated carbon particles.

[0032] like Figure 5 As shown, in this embodiment, the screening plate 40 is fixedly connected to two L-shaped plates 41. Several fixing bolts 42 are provided on the top of the L-shaped plates 41. The top of the L-shaped plates 41 is attached to the top surface of the screening frame 10. The fixing bolts 42 pass through the top of the L-shaped plates 41 and the top of the screening frame 10, and the L-shaped plates 41 are fixed to the screening frame 10 by the fixing bolts 42.

[0033] In practice, the L-shaped plate 41 can support the screening plate 40, and the L-shaped plate 41 can be fixed to the screening frame 10 by fixing bolts 42. In this way, when the screening frame 10 vibrates, the screening frame 10 can smoothly drive the screening plate 40 to vibrate.

[0034] like Figure 3 and Figure 5As shown, in this embodiment, two fixing plates 12 are fixedly connected to the top of the screening frame 10, and two positioning plates 31 are fixedly connected to the top of the screening plate 30. Both the fixing plate 12 and the positioning plate 31 are provided with a number of round holes 60. The positioning plate 31 is provided with a number of positioning bolts 32. The positioning bolts 32 pass through the round holes 60 on the corresponding positioning plate 31 and the fixing plate 12. The fixing plate 12 and the positioning plate 31 are fixed to each other by the positioning bolts 32. The arc plate 13 is fixedly connected with a filling block 14 that is slidably connected to the adjacent positioning plate 31. The filling block 14 can block the side of the positioning plate 31 to avoid the accumulation of activated carbon particles as much as possible.

[0035] In practice, after fixing the fixed plate 12 and the fixed plate 31 with several positioning bolts 32, the angle of the screening plate 30 can be limited. The screening plate 40 can be fixed on one side of the screening plate 30 by the screw 70. In this way, the screening plate 30 can be fixed on the screening frame 10. When the screening frame 10 vibrates, the screening plate 30 can vibrate, thereby smoothly screening the activated carbon particles. The positioning bolts 32 can be removed from the round holes 60 on the positioning plate 31 and the fixed plate 12. Then, the angle of the screening plate 30 can be adjusted as needed to align the round holes 60 on the positioning plate 31 with the other round holes 60 on the fixed plate 12. Then, the positioning bolts 32 can be reinserted into the round holes 60 on the positioning plate 31 and the fixed plate 12 to re-fix the positioning plate 31 and the fixed plate 12.

[0036] When the positioning bolt 32 is removed from the positioning plate 31 and the fixing plate 12, and the fixing bolt 42 is removed from the L-shaped plate 41 and the screening frame 10, the screening plate 30 can be moved upward through the positioning plate 31, and the screening plate 40 can be moved upward through the L-shaped plate 41. In this way, screening plates 30 and 40 with different screening hole diameters can be replaced as needed. After removing screening plates 30 and 40, the nuts can be unscrewed, and the screw 70 can be pulled out from the connecting seat 34 and the limiting seat 44. In this way, screening plates 30 and 40 can be separated, and screening plates 30 or 40 can be replaced individually.

[0037] Example 2

[0038] Based on Example 1, such as Figure 4-6 As shown, in this embodiment, the screening plate 30 is provided with an arc-shaped groove 33, and the screening plate 40 is fixedly connected with a pad 43 that is slidably connected to the arc-shaped groove 33. The pad 43 is arc-shaped, and the axes of the arc-shaped groove 33 and the pad 43 are both coincident with the axis of the screw 70.

[0039] In specific implementation, the pad 43 can block the gap between the first sieve plate 30 and the second sieve plate 40, preventing activated carbon particles from entering between the first sieve plate 30 and the second sieve plate 40. This facilitates the smooth passage of activated carbon particles between the first sieve plate 30 and the second sieve plate 40 through the pad 43. When the first sieve plate 30 rotates relative to the second sieve plate 40, the first sieve plate 30 can move relative to the pad 43, causing the arc groove 33 to move relative to the pad 43.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
