[0016] The beneficial effects of the novel zinc oxide waste residue treatment equipment of the present invention:

[0018] 2. By providing a guiding mechanism, the arc-shaped block quickly rebounds to push the support block, increasing the reciprocating speed of the support block. Through transmission, the 40-mesh sieve reciprocates relatively fast, so that the zinc oxide after grinding is dispersed on the 40-mesh sieve to avoid accumulation. Moreover, when the sliding plate moves, it can also impact the impact block to generate vibration, reducing the probability of sieve holes being blocked and making the screening effect better.

[0019] 3. By providing a return material mechanism, when the electric telescopic rod expands and contracts, the sliding plate can be driven to flip through the meshing of the gear and the toothed plate, so that the 40-mesh sieve faces downward to pour out unqualified zinc oxide particles, avoiding the accumulation of particles on the 40-mesh sieve and affecting the screening.

Specific Embodiments

[0029] To make the above objects, features, and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0030] Example 1, referring to Figures 1 to 7, which is the first embodiment of the present invention. This embodiment provides a new type of zinc oxide waste residue treatment device, which can automatically grind zinc oxide and automatically screen the ground zinc oxide. It includes a rotary kiln 1, on which a mixer 2 is provided. The mixer 2 is provided with a first feed pipe and a second feed pipe 3 for supplying raw materials. The upper end of the second feed pipe 3 is fixedly connected to a hopper 4 with a closed upper end. A feed pipe extending into the hopper 4 is provided at the outer end of the hopper 4; a grinding mechanism, which is arranged on the hopper 4 and grinds the raw materials; a screening mechanism, which is arranged between the hopper 4 and the second feed pipe 3 and screens the ground raw materials; a swinging mechanism, which is arranged on the side wall of the hopper 4 and provides power for the shaking of the screening mechanism; a guiding mechanism, which is arranged at the top of the hopper 4 and guides the swinging mechanism to increase the swing; a return material mechanism, which is arranged on the right side of the hopper 4 and collects the raw materials that do not meet the requirements on the screening mechanism.

[0031] Specifically, when the rotary kiln 1 processes zinc oxide waste residue, it is generally in the form of co-incineration. The ratio of its raw materials to zinc oxide waste residue is 1:0.35. The setting of the mixer 2 can mix the raw materials and zinc oxide waste residue to ensure the mixing effect. This is the prior art and will not be elaborated here.

[0032] Furthermore, the grinding mechanism includes a motor 51 fixed to the hopper 4 through a connecting plate. An installation opening is provided at the top of the hopper 4. The output shaft of the motor 51 penetrates the installation opening and is fixedly connected to a grinding disc 52; the diameters of the upper and lower ends of the grinding disc 52 are both smaller than the middle diameter, and the upper and lower ends of the grinding disc 52 are conical; the screening mechanism includes an installation box 61 arranged on the hopper 4 and communicating with the hopper 4. The right end of the installation box 61 is open. A sliding plate 62 is slidably connected inside the installation box 61. An impact block 63 cooperating with the sliding plate 62 is fixedly connected to the inner wall of the installation box 61. A first spring 64 is fixedly connected to the inner side wall of the installation box 61. The right end of the first spring 64 abuts against the sliding plate 62. A round opening cooperating with the bottom of the hopper 4 is provided on the sliding plate 62, and a 40-mesh sieve 65 is fixedly connected inside the round opening; the diameters of the lower end of the second feed pipe 3 and the hopper 4 are equal. A guiding ring 66 is fixedly connected to the inner side wall of the hopper 4. The cross-section of the guiding ring 66 is arc-shaped, and the bottom of the guiding ring 66 is close to the upper end surface of the sliding plate 62.

[0033] Among them, during the incineration process of zinc oxide waste residue, it is required that the particles of zinc oxide waste residue are not larger than 0.5 mm. Therefore, a 40-mesh sieve 65 (with a sieve hole diameter of 0.425 mm) is selected here. The upper and lower ends of the grinding disc 52 are both conical, so as to facilitate the upper material to enter the grinding disc 52 for grinding, and the lower end is conical for convenient feeding. The setting of the guiding ring 66 can prevent the ground zinc oxide waste residue from falling onto the sliding plate 62 when the sliding plate 62 moves. Here, a bracket for supporting the motor 51 is fixed on the side wall of the hopper 4 (blocked in the figure).

[0034] Preferably, the swing mechanism includes an electric telescopic rod 71 fixed to the side wall of the hopper 4 by a clamp, a T-shaped plate 72 is fixedly connected to the electric telescopic rod 71, a support opening is provided on the T-shaped plate 72, a rotating shaft is rotatably connected in the support opening, an L-shaped rotating plate 73 is fixedly connected to the rotating shaft, a torsion spring 74 is provided on the rotating shaft, a transmission shaft 75 is rotatably connected to the rotating plate 73, a T-shaped block 76 is fixedly connected to the transmission shaft 75, and a sliding plate 62 is provided with a The T-slot 77 is elastically connected to the inner wall of the T-slot 77 through a second spring 78; a power member 79 for toggling the rotating plate 73 is provided on the output shaft of the motor 51; the power member 79 includes a disk 791 fixedly connected to the output shaft of the motor 51, and a plurality of arc blocks 792 are provided on the disk 791. A supporting block 793 cooperating with the arc blocks 792 is fixedly connected to the rotating plate 73, and the distance between two adjacent arc blocks 792 is greater than the width of the supporting block 793.

[0035] It should be noted that the arrangement of the T-shaped block 76 and the T-shaped slot 77 prevents the T-shaped block 76 from getting stuck during the rotation of the rotating plate 73. The torsion spring 74 is elastic enough to ensure that the rotating plate 73 can be reset. The side walls of the arc block 792 and the support block 793 are both provided with arc edges to prevent the arc block 792 and the support block 793 from getting stuck.

[0036] During use, first, the feeding pipe feeds materials into the hopper 4. Here, the feeding pipe penetrates through the upper end of the feeding hopper 4. Then, the motor 51 is started. The output shaft of the motor 51 rotates to drive the grinding disc 52 to rotate for grinding the zinc oxide waste residue. The ground zinc oxide directly falls onto the 40-mesh sieve 65. There is a gap between the upper end surface of the 40-mesh sieve 65 and the upper end surface of the slide plate 62, so as to accommodate a certain amount of zinc oxide. When the output shaft of the motor 51 rotates, the disc 791 is driven to rotate. When there is a clearance fit between the support block 793 and two adjacent arc-shaped blocks 792, the torsion spring 74 does not obtain elasticity. As the output shaft of the motor 51 rotates, the disc 791 rotates, driving the arc-shaped plate to abut against the support block 793. At this time, the arc edges provided on the arc-shaped plate and the support block 793 prevent the arc-shaped plate and the support block 793 from getting stuck. Since the disc 791 is fixed on the output shaft of the motor 51 and cannot be pushed, under the extrusion force, the support block 793 moves away from the output shaft of the motor 51, the rotating plate 73 deflects, the torsion spring 74 obtains elasticity, and the T-shaped block 76 moves towards the first spring 64, causing the slide plate 62 to move towards the first spring 64, driving the first spring 64 to compress. Then, as the disc 791 continues to rotate, the support block 793 is again in clearance fit with the two arc-shaped blocks 792. At this time, under the action of the torsion spring 74, the rotating plate 73 resets, and the first spring 64 causes the slide plate 62 to reset and move away from the first spring 64. As the output shaft of the motor 51 rotates continuously, through transmission, the slide plate 62 reciprocates left and right, and the 40-mesh sieve 65 reciprocates left and right to screen the ground zinc oxide, ensuring the particle size of the fed zinc oxide.

[0037] In summary, by setting the grinding mechanism and the screening mechanism, during the grinding process, the 40-mesh sieve 65 can be driven to reciprocate left and right through transmission to screen the ground zinc oxide, ensuring that the particles of the fed zinc oxide meet the requirements. Moreover, the grinding and the 40-mesh sieve 65 share the power of the same motor 51, without the need for external power, making it more convenient to use.

[0038] Example 2, refer to Figures 1 to 7, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a guiding mechanism for the new zinc oxide waste residue treatment equipment, solving the problem of how to achieve better screening effect. It includes a plurality of receiving grooves 81 provided on the disc 791. The arc-shaped block 792 is elastically connected to the inner wall of the receiving groove 81 through the third spring 82. A strip-shaped opening 83 is provided on the inner wall of the receiving groove 81. A guiding rod 84 fixed to the arc-shaped block 792 is slidably connected in the strip-shaped opening 83. A first arc-shaped groove 85 is provided at the top of the hopper 4. One end of the first arc-shaped groove 85 is communicated with a transverse groove 88. A second arc-shaped groove 86 is provided inside the first arc-shaped groove 85. One end of the second arc-shaped groove 86 is communicated with the front end of the first arc-shaped groove 85 through a third arc-shaped groove 87. The other end of the second arc-shaped groove 86 is communicated with the rear end of the first arc-shaped groove 85 through the transverse groove 88. The guiding rod 84 cooperates with the first arc-shaped groove 85, the second arc-shaped groove 86, the third arc-shaped groove 87, and the transverse groove 88.

[0039] It should be noted that in Embodiment 1, the arc-shaped block 792 is fixedly connected to the side wall of the disc 791. In this embodiment, the arc-shaped block 792 is not fixed to the disc 791 but slides in the receiving groove 81. Here, the first arc-shaped groove 85 is provided outside the second arc-shaped groove 86, so that the diameter of the circle corresponding to the first arc-shaped groove 85 is larger than the diameter of the circle corresponding to the second arc-shaped groove 86.

[0040] During use, during the rotation of the disc 791, the guiding rod 84 first slides in the first arc-shaped groove 85. When the arc-shaped block 792 is about to approach the support block 793, the guiding rod 84 moves into the third arc-shaped groove 87. Continuing to move, the guiding rod 84 will move along the third arc-shaped groove 87 into the second arc-shaped groove 86. At this time, the arc-shaped block 792 moves towards the inside of the receiving groove 81, and the third spring 82 is compressed. Before the arc-shaped block 792 contacts the support block 793, the arc-shaped block 792 completely moves to the left of the support block 793. At this time, the guiding rod 84 is in the second arc-shaped groove 86 and cannot move outwards. When the middle position of the arc of the arc-shaped block 792 is directly opposite to the support block 793, the guiding rod 84 moves to the connection between the transverse groove 88 and the second arc-shaped groove 86. At this time, the guiding rod 84 can move outwards along the transverse groove 88. Under the action of the third spring 82, the arc-shaped block 792 quickly resets and quickly pushes the support block 793 to reset. Through transmission, the slide plate 62 quickly moves towards the first spring 64. And when the support block 793 resets, the first spring 64 also quickly rebounds. Thus, when the slide plate 62 reciprocates, there is a certain speed, making the screening effect better (mainly because when the reciprocating speed is relatively fast, the inertia of the zinc oxide particles is relatively large, so that the ground zinc oxide is dispersed on the 40-mesh sieve 65 and is not easy to accumulate). And because the speed is relatively fast, the instantaneous impact is relatively large, making the first spring 64 compressed greatly, causing the slide plate 62 to hit the impact block 63 to generate vibration, reducing the probability of the sieve holes being blocked, and making the screening effect better.

[0041] In summary, by setting the guiding mechanism, the support block 793 is reset by the rebound of the quick arc block 792, so that the reciprocating speed of the support block 793 is increased. Through transmission, the reciprocation of the slide plate 62 is relatively fast, so that the ground zinc oxide is dispersed on the 40-mesh sieve 65 to avoid accumulation. When the slide plate 62 moves, it can also impact the impact block 63 to generate vibration, reducing the probability of blockage of the sieve holes and making the screening effect better.

[0042] Example 3. Refer to Figures 1 to 7 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a return material mechanism for the new zinc oxide waste residue treatment equipment, which solves the problem of how to collect the unqualified zinc oxide particles on the 40-mesh sieve 65. It includes a receiving port 91 provided on the mounting box 61. The transmission shaft 75 extends into the receiving port 91. The front and rear ends of the transmission shaft 75 penetrate through the mounting box 61. A gear 92 is fixedly connected to the transmission shaft 75. A bearing plate 93 is fixedly connected to the mounting box 61. A toothed plate 94 that cooperates with the gear 92 is fixedly connected to the bearing plate 93. An inclined surface 95 is provided on the slide plate 62; a recovery member 96 for collecting and screening unqualified raw materials is provided at the upper end of the mixer 2; the recovery member 96 includes a bottom plate 961 fixedly connected to the mixer, a recovery box 962 is fixedly connected to the bottom plate 961, and a slideway that cooperates with the slide plate 62 is provided on the recovery box 962.

[0043] Specifically, when the slide plate 62 moves to the right, it is always between the two bearing plates 93 and will not collide with the two bearing plates 93. The toothed plate 94 causes the gear 92 to rotate more than 90°, at this time the 40-mesh sieve 65 will tilt downward to pour out the unqualified materials in the 40-mesh sieve 65.

[0044] During use, when there is a large amount of unqualified zinc oxide in the 40-mesh sieve 65, it is necessary to pour out the zinc oxide. At this time, the motor 51 stops rotating, the electric telescopic rod 71 extends, pushing the T-shaped plate 72 to move to the right. Through transmission, the slide plate 62 is driven to move to the right. When the slide plate 62 moves, the gear 92 abuts against the bearing plate 93 to support the slide plate 62. When the left end of the slide plate 62 leaves the installation box 61, the toothed plate 94 meshes with the gear 92, and the T-shaped plate 72 is continuously pushed, so that the slide plate 62 continues to move. The gear 92 meshes with the toothed plate 94, causing the transmission shaft 75 to rotate counterclockwise (observed from the front view direction of the transmission shaft 75). Thus, the T-shaped block 76 rotates, driving the slide plate 62 to rotate counterclockwise around the transmission shaft 75, making the 40-mesh sieve 65 tilt downward, pouring out the zinc oxide that does not meet the diameter on the 40-mesh sieve 65, and then falling into the recycling box 962 through the slideway, avoiding accumulation and affecting the screening of the 40-mesh sieve 65. Then, the reverse operation is performed to reset the slide plate 62. When the slide plate 62 is reset, even if the T-shaped plate 72 automatically drops a little under the gravity of the slide plate 62, since the left end of the slide plate 62 is provided with an inclined surface 95, the phenomenon of jamming between the slide plate 62 and the installation box 61 can be avoided. It should be noted that the sliding distance of the T-shaped block 76 in the T-shaped groove 77 needs to be set to be less than the projection height from the upper end of the inclined surface 95 to the bottom of the T-shaped block 76, so as to ensure that the slide plate 62 smoothly enters the installation box 61.

[0045] In summary, by setting the return material mechanism, when there are a large number of unqualified zinc oxide particles on the 40-mesh sieve 65, only the electric telescopic rod 71 needs to be started, and the unqualified zinc oxide particles on the 40-mesh sieve 65 can be automatically poured out, avoiding the blockage of the sieve by unqualified zinc oxide and ensuring the screening effect of the 40-mesh sieve 65.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
