A flap is symmetrically rotated below the two crushing rollers within the crushing box. The flap has a linear array of material leakage channels on its side, with an intercepting rod between each pair of material leakage channels. The intercepting rods on the two flaps are respectively inserted into the material leakage channels on each other. The material leakage channels are open when the two flaps are tilted down, and closed when the two flaps are at the same horizontal level.

[0007] Preferably, the outer wall of one side of the crushing box has a discharge port that communicates with the inside of the crushing box, and a sealing plate is slidably arranged inside the crushing box on the side of the discharge port.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1-7 This utility model provides a technical solution, including the following embodiments: Example 1 Combination Figure 2 and Figure 3 This embodiment is designed to address the problem that traditional pulverizers cannot effectively separate the catalyst from pulverized three-way catalytic converters, thus affecting subsequent recycling and other processes.

[0022] Specifically, two main motors 27 are fixedly installed on the crushing box 1, and the output ends of the main motors 27 are respectively fixedly installed on one end of the shaft of the crushing roller 2. The three-way catalytic converter is crushed by the two crushing rollers 2, and the crushed three-way catalytic converter fragments fall onto two flaps 41. By tilting the two flaps 41 into a downward state, the material leakage trough 42 is opened. At this time, the iron pieces in the three-way catalytic converter fragments are filtered through the material leakage trough 42 and the intercepting rod 43, and the catalyst falls and separates from the material leakage trough 42. This sorting reduces the need for subsequent sorting processes.

[0023] Example 2 Combination Figure 4 As shown, this embodiment is designed to address the problem of how to quickly feed pulverized three-way catalytic converter fragments.

[0024] Specifically, by flipping the two flaps 41 upwards from their downward position, the filtered three-way catalytic converter fragments are supported by the two flaps 41 at the same level, facilitating their discharge from the outlet 12. To accelerate the detachment of the three-way catalytic converter fragments, when the two flaps 41 are flipped downwards, the sealing plate 5 sliding on the crushing chamber 1 slides down under gravity to block the outlet 12, thus preventing the three-way catalytic converter fragments supported on the flaps 41 from detaching from the outlet 12. When the flaps 41 are flipped upwards, the flaps 41 push the push rod 51, causing the sealing plate 5 to slide upwards and open the outlet 12, allowing the three-way catalytic converter fragments on the flaps 41 to be discharged along the outlet 12. Furthermore, the flipping of the flaps 41 controls the sliding opening and closing of the sealing plate 5 at the outlet 12. Moreover, the flaps 41 are fixedly welded to the mounting rod 4. Two mounting rods 4 are rotatably mounted on the crushing chamber 1, while the side of the flap 41 maintains a predetermined angle with the mounting rods 4, that is, the side of the flap 41 is inclined downward relative to the mounting rods 4, and maintains an angle of 2 to 4 degrees with the mounting rods 4. Thus, when the two flaps 41 are flipped with the mounting rods 4 to be on the same horizontal plane, the three-way catalytic converter fragments slide off the flaps 41 through the downwardly inclined flaps 41.

[0025] Example 3 Combination Figure 2 As shown, in order to control the flipping of the two flaps 41 without using more drive sources.

[0026] Specifically, such as Figure 6 As shown, a main gear 21 is fixedly mounted on the shaft of the crushing roller 2. The main gear teeth 23 on the drive disc 22 partially mesh with the main gear 21. Figure 6 As can be seen, the main gear 23 is one-seventh the size of a normal gear. An eccentric rod 24 is fixedly mounted on the drive disc 22. A second pulley 44 is fixedly mounted on one end of the shaft of the mounting rod 4, and a first pulley 25 is fixedly mounted on one end of the shaft of the drive disc 22. The second pulley 44 and the first pulley 25 are driven by a belt. When the crushing roller 2 rotates forward to crush the three-way catalytic converter, the main gear 21 meshes with the main gear 23 until the last tooth, at which point the flap 41 tilts down to its maximum angle. When the crushing roller 2 rotates in the reverse direction, the main gear 21 meshes with the main gear 23 again until the last tooth on the other end. At this time, the two flaps 41 are on the same horizontal plane to facilitate material removal. The catalyst is recovered by screening the crushed three-way catalytic converter fragments through the collection box 3.

[0027] Example 4 Combination Figure 2 As shown, this is done in order to improve the feeding rate and achieve better screening.

[0028] Specifically, a mounting block 11 is fixedly welded onto the crushing box 1, and the two ends of the main spring 26 are respectively fixedly mounted on the mounting block 11 and the eccentric rod 24, as shown below. Figure 6 As shown, when the main gear 21 and the main tooth 23 are engaged at the middle position, the main spring 26 has its minimum stored force. When the main gear 21 and the main tooth 23 are engaged to the last tooth, the main spring 26 remains in a stored state, causing the last tooth of the main tooth 23 to remain close to the tooth of the main gear 21. Thus, when the main gear 21 rotates, it continuously impacts the last tooth of the main tooth 23, causing the drive disc 22 to reciprocate slightly. This rotation causes the flap 41, which is connected to it, to reciprocate and rotate. When the flap 41 is tilted to its maximum angle or when both flaps 41 are on the same horizontal plane, the vibration of the flap 41 accelerates the unloading or vibration screening process, facilitating the removal of catalyst from the three-way catalytic converter fragments.

[0029] Working principle: Two main motors 27 drive two crushing rollers 2 to rotate synchronously in opposite directions. The main gear 21 and the main tooth 23 mesh with the last tooth, at which point the flap 41 tilts down to its maximum angle. The two crushing rollers 2 then crush the three-way catalytic converter, and the crushed three-way catalytic converter falls onto the flap 41. At the same time, as the main gear 21 rotates, it continuously impacts the last tooth of the main tooth 23. When the main gear 21 and the main tooth 23 mesh with the last tooth, the main spring 26 remains in a charged state, which keeps the last tooth of the main tooth 23 close to the tooth of the main gear 21. As the main gear 21 rotates, it continuously impacts the last tooth of the main tooth 23, causing the drive disc 22 to reciprocate slightly. This rotation causes the flap 41, which is connected to it, to vibrate and rotate repeatedly, accelerating the screening process. Then, by causing the two crushing rollers 2 to rotate in opposite directions, the main gear 21 meshes again with the main tooth 23 to the last tooth at the other end. At this time, the two flaps 41 are on the same horizontal plane, and the main spring 26 remains in a charged state, thereby driving the other last tooth of the main tooth 23 to always be close to the tooth of the main gear 21, so that the flaps 41 continue to vibrate and discharge material. Furthermore, in order to further prevent dust during the crushing of the three-way catalytic converter, a mounting frame 6 with an internal cavity is included, and a tempered glass cover 62 is hinged to the cavity opening. The top of the mounting frame 6 is fixedly connected to the feed pipe 61. The crushing box 1 is fixedly installed in the mounting frame 6 with bolts, and the tempered glass cover 62 covers the cavity on the mounting frame 6. When the three-way catalytic converter is put into the crushing box 1 along the feed pipe 61, the mounting frame 6 provides a certain degree of shielding, thereby reducing the dust generated during crushing.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
