[0032] 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.

[0033] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a sulfur recovery device, comprising a body 1. The top of the body 1 has a feed inlet, and the bottom has a discharge outlet, allowing sulfur raw materials to be poured into the body 1 through the feed inlet for crushing and grinding. The processed sulfur is then discharged from the discharge outlet. A motor 2 is fixedly connected to the rear end of the body 1. A support is provided on the outer wall of the motor 2 to support it. A gear a3 is fixedly connected to the output shaft of the motor 2, and a gear b4 meshes with the outer wall of gear a3. Two sets of crushing rollers 7 are rotatably connected to the top of the inner wall of the body 1. The rotating central shaft is fixedly connected to the rotating central shafts of gears a3 and b4. Through the meshing of gears a3 and b4, the two sets of crushing rollers 7 can rotate in opposite directions at the top of the machine body 1 to perform preliminary crushing of the sulfur raw material. Gear a3 is rotatably connected to the outer side wall of the machine body 1, and gear b4 is rotatably connected to the outer side wall of the machine body 1. A pulley a5 is fixedly connected to the surface of gear b4. The pulley a5 is connected to the pulley b6 through a transmission belt. When gear a3 meshes with gear b4 and rotates, it will drive the pulley a5 to rotate synchronously with it, thereby driving the pulley b6 to rotate synchronously.

[0034] Reference Figure 2 and Figure 3 The rotating shaft 10 is fixedly connected to the rotating center shaft of the pulley b6. The inner side wall of the machine body 1 is in contact with the primary filter frame 8. The primary filter frame 8 is conical in shape and has multiple sets of filter holes on its surface. After the sulfur raw material is crushed by the two sets of crushing rollers 7, the sulfur raw material that is not completely crushed will enter the interior of the secondary grinding chamber 9 through the inclined surface of the primary filter frame 8. The crushed sulfur will be discharged outward from the feed port at the bottom of the machine body 1 through the filter holes on its surface. The secondary grinding chamber 9 is fixedly connected to the inner wall of the machine body 1, and the surface of the rotating shaft 10 is provided with a grinding and unblocking mechanism.

[0035] Reference Figure 2 - Figure 4The grinding and unblocking mechanism includes a rotating wheel 11. A circular groove is provided on the side wall of the secondary grinding chamber 9. The rotating wheel 11 is rotatably connected to the inner wall of the circular groove in the secondary grinding chamber 9. By providing a circular groove on the side wall of the secondary grinding chamber 9, the rotating wheel 11 drives the grinding roller 12 to rotate around the center of the rotating shaft 10 when it rotates, so as to perform secondary grinding and crushing on the sulfur raw material entering the secondary grinding chamber 9. The rotating wheel 11 is fixedly connected to the surface of the rotating shaft 10. A protrusion is provided on the side of the rotating wheel 11 away from the center point, and the protrusion is fixed to the groove of the grinding roller 12 away from the center point, so that the rotating wheel 11 drives the grinding roller 12 to rotate around the center of the rotating wheel 11 when it rotates. The rotating shaft 10 passes through and is rotatably connected to the inner side wall of the secondary grinding chamber 9, and the rotating shaft 10 passes through and is rotatably connected to the inner wall of the grinding roller 12.

[0036] Reference Figure 3 The rotating shaft 10 is rotatably connected to the inner side wall of the machine body 1. One end of the return spring 13 is fixedly connected to the inner wall of the grinding roller 12, and the other end of the return spring 13 is fixedly connected to the outer wall of the rotating block 14. The function of the return spring 13 is that when the unclogging ball 15 disengages from the inner wall of the filter hole of the secondary grinding chamber 9, it will be pressed by the inner wall of the filter hole, and drive the rotating block 14 to move on the inner wall of the grinding roller 12. When it reaches the next set of filter holes, it will be automatically reset by the elastic action of the return spring 13. The grinding roller 12 is fixedly connected to the surface of the rotating wheel 11. The rotating block 14 is elastically connected to the inner wall of the grinding roller 12 through the return spring 13. The rotating block 14 is slidably connected to the inner wall of the grinding roller 12. The unclogging ball 15 is slidably connected to the inner wall of the grinding roller 12. The surface of the rotating block 14 rotates. A cleaning ball 15 is connected to the secondary grinding chamber 9. The rotational connection between the two prevents the cleaning ball 15 from rotating when it comes into contact with the filter holes of the secondary grinding chamber 9, thus causing the return spring 13 to twist. The inner wall of the secondary grinding chamber 9 has multiple sets of filter holes. The outer wall of the cleaning ball 15 contacts the inner wall of the filter holes. The contact between the two allows the cleaning ball 15 to clear the filter holes of the secondary grinding chamber 9, preventing the powdered sulfur from clogging the filter holes of the secondary grinding chamber 9 and reducing the feeding efficiency. At the same time, when the grinding roller 12 rotates around the center, one side always remains in a relative state with the inner wall of the secondary grinding chamber 9. The cleaning ball 15 is located on the inner wall of the grinding roller 12, away from the grinding contact surface between the grinding roller 12 and the secondary grinding chamber 9.

[0037] Reference Figure 3 - Figure 5The surface of the rotating shaft 10 is also provided with a vibration mechanism, which includes a cam 16. The outer wall of the cam 16 contacts a contact block 17. By rotating the cam 16, it contacts the contact block 17, which can push the contact block 17 to move the primary filter frame 8 upward on the surface of the secondary grinding chamber 9. After the contact is released, the primary filter frame 8 will be automatically reset by the elastic action of the connecting spring 18. This process is repeated to achieve the vibration effect of the primary filter frame 8, thereby preventing the sulfur raw material from being adsorbed on the surface of the primary filter frame 8 due to moisture. The primary filter frame 8 is elastically connected to the outer wall of the secondary grinding chamber 9 by the connecting spring 18. One end of the connecting spring 18 is fixedly connected to the outer side wall of the secondary grinding chamber 9, and the other end of the connecting spring 18 is fixedly connected to the surface of the bottom end of the primary filter frame 8. The primary filter frame 8 is slidably connected to the outer wall of the secondary grinding chamber 9, and the cam 16 is fixedly connected to the surface of the rotating shaft 10.

[0038] Working principle: When motor 2 is started, the output shaft of motor 2 drives gear a3 to rotate. Since gear a3 meshes with gear b4, gear b4 rotates accordingly. The rotation of gears a3 and b4 respectively drives the crushing rollers 7 connected to them to rotate in opposite directions at the top of the machine body 1. At this time, the sulfur raw material poured into the machine body 1 from the feed port is initially crushed under the squeezing of the two sets of crushing rollers 7 rotating in opposite directions. While gear a3 drives gear b4 to rotate, the pulley a5 on gear b4 also rotates. Through the transmission belt, it drives pulley b6 to rotate, which in turn drives the rotating shaft 10 connected to it to rotate, providing power for subsequent grinding and unblocking operations.

[0039] The sulfur raw material, initially crushed by the crushing roller 7, enters the primary filter frame 8. The sulfur raw material that is not completely crushed will enter the secondary grinding chamber 9 along the inclined surface of the primary filter frame 8. The sulfur that has been crushed to the required particle size will pass through the filter holes on the surface of the primary filter frame 8 and be discharged from the discharge port at the bottom of the machine body 1. Inside the secondary grinding chamber 9, as the rotating shaft 10 rotates, the rotating wheel 11 fixed on the rotating shaft 10 rotates synchronously. The rotating wheel 11 drives the grinding roller 12 to rotate around the center of the rotating wheel 11 through the protrusion, and performs secondary grinding and crushing on the sulfur raw material entering the secondary grinding chamber 9. At the same time, during the rotation of the grinding roller 12, the unblocking ball 15 on its inner wall will continuously contact the filter holes on the inner wall of the secondary grinding chamber 9 under the action of the return spring 13 and the rotating block 14. When the unblocking ball 15 contacts the filter hole, it will unblock the filter hole and prevent the powdered sulfur from clogging the filter hole, ensuring that the sulfur that has been ground twice can pass through the filter hole smoothly and be discharged from the discharge port.

[0040] Simultaneously, as the rotating shaft 10 rotates, the cam 16 fixed on the rotating shaft 10 rotates synchronously. When the cam 16 rotates and contacts the contact block 17, it pushes the contact block 17 to move the primary filter frame 8 upward on the surface of the secondary grinding chamber 9. When the cam 16 rotates away from the contact block 17, the primary filter frame 8 automatically resets under the elastic action of the connecting spring 18. This process repeats, causing the primary filter frame 8 to vibrate. This vibration can effectively prevent the sulfur raw material from adsorbing onto the surface of the primary filter frame 8 due to moisture or other reasons, ensuring the filtration effect of the primary filter frame 8 and guaranteeing the efficient operation of the entire sulfur recovery device.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
