[0032] The following describes preferred embodiments of the present invention in greater detail. Although preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0033] like Figure 1 As shown, the utility model provides a crystallizer discharging device, comprising:

[0034] The shell 1 has a material inlet at the upper side of one end and a material outlet 27 at the lower side of the other end. At least one pair of stirring and conveying shafts are provided inside the shell 1.

[0035] A driving component is arranged outside one end of the housing 1 and is connected to a stirring and conveying shaft through a torque clutch mechanism. The torque clutch mechanism can slip when the transmitted torque is greater than the set torque;

[0036] The transmission component is arranged on the outside of the other end of the shell 1. The transmission component can make a pair of stirring and conveying shafts rotate synchronously towards each other.

[0037] Specifically, in order to solve the problem in the prior art that the motor may be damaged as the torque of the spiral blade increases during the discharging process of the crystallizer discharging device, the crystallizer discharging device provided by the utility model is provided with stirring and conveying shafts in pairs in the shell 1. Under the action of the driving component and the transmission component, the pair of stirring and conveying shafts can rotate synchronously in opposite directions, thereby stirring and conveying the material, and conveying the material from the material inlet to the material outlet 27. The torque clutch mechanism between the driving component and the stirring and conveying shaft can slip when the transmitted torque is greater than the set torque, thereby avoiding the increase in the transmitted torque caused by material jamming, and thereby avoiding damage to the drive motor 22 of the driving component.

[0038] In this embodiment, the transmission component includes a pair of mutually meshing gears, and the two gears are respectively connected to a stirring and conveying shaft.

[0039] Optionally, the stirring and conveying shaft includes a shaft body 2 and stirring and conveying blades 26 provided on the outer periphery of the shaft body 2 .

[0040] Specifically, the stirring and conveying shaft has a shaft body 2 rotatably connected to the shell 1 , and a spiral stirring and conveying blade 26 is provided on the periphery of the shaft body 2 , which can convey the material from the material inlet to the material outlet 27 while stirring the material.

[0041] Optionally, the driving component includes:

[0042] The driving motor 22 is connected to the housing 1 , and the output shaft of the driving motor 22 is connected to the driving belt 25 pulley 23 ;

[0043] The driven belt 25 wheel 24 has a rotating shaft at its center. The driven belt 25 wheel 24 is connected to the driving belt 25 wheel 23 through a belt 25. The rotating shaft is connected to the input end of the torque clutch mechanism, and the output end of the torque clutch mechanism is connected to the shaft body 2.

[0044] Specifically, the driving motor 22 drives the rotating shaft to rotate through the belt 25, and the rotating shaft transmits torque to the stirring and conveying shaft through the torque clutch mechanism.

[0045] Optionally, the torque clutch mechanism includes:

[0046] The fixing sleeve 3 has a plurality of guide grooves 9 evenly distributed along the circumference;

[0047] Two transmission shafts 4 are disposed in the fixed sleeve 3. The ends of the two transmission shafts 4 that are close to each other are rotatably connected by an intermediate rod 17. The ends of the two transmission shafts 4 that are far away from each other respectively form the input end and output end of the torque clutch mechanism. The outer periphery of the transmission shaft 4 is provided with a transmission plane.

[0048] Multiple sliders 12, two sliders 12 are slidably arranged in each guide groove 9, and the two sliders 12 in each guide groove 9 are respectively matched with a transmission shaft 4. The end of the slider 12 close to the transmission shaft 4 is connected to the top plate 14 through the first elastic component 13. When the top plate 14 supports the transmission plane under the action of the first elastic component 13, torque transmission can be achieved.

[0049] Specifically, such as Figure 2 and Figure 3As shown, a rotating hole 16 is provided at the ends of the two transmission shafts 4 close to each other, and an intermediate rod 17 is rotatably inserted in the rotating hole 16. The setting of the intermediate rod 17 ensures that the two rotating shafts are in a coaxial state. The two sliders 12 in each guide groove 9 are respectively connected to a transmission shaft 4, and the end of the slider 12 close to the transmission shaft 4 is elastically connected to a top plate 14. The top plate 14 is pressed against the transmission plane of the transmission shaft 4 under the action of the first elastic component 13, so that when one transmission shaft 4 rotates, the other transmission shaft 4 can follow its rotation and transmit torque. However, when the torque is too large, the top plate 14 overcomes the elastic force of the first elastic component 13 during the rotation of the transmission shaft 4, and the top plate 14 jumps up, and the torque clutch mechanism slips.

[0050] In this embodiment, a plurality of transmission planes are evenly distributed on the outer circumference of the transmission shaft 4 , and each transmission plane corresponds to a slider 12 .

[0051] In this embodiment, chamfers 15 are provided around the contact surface between the top plate 14 and the transmission plane.

[0052] Optionally, a raised portion 11 is provided on the inner periphery of the fixed sleeve 3, and a guide slope is formed on both sides of the raised portion 11. A guide protrusion that cooperates with the guide slope is provided on the outer side of the slider 12, so that when the slider 12 slides along the guide groove 9, it can move toward or away from the transmission shaft 4 under the action of the guide slope.

[0053] Specifically, due to the arrangement of the raised portion 11, the inner circumference of the fixed sleeve 3 forms a structure that gradually contracts and then expands from one end to the other end. The guide slopes formed on both sides of the raised portion 11 cooperate with the guide protrusions on the outer side of the slider 12. As the slider 12 slides along the guide groove 9, the slider 12 also moves toward or away from the transmission shaft 4, which can change the compression amount of the first elastic component 13, change the pressure of the top plate 14 on the transmission plane, and thus change the magnitude of the torque that can be transmitted by the torque clutch mechanism.

[0054] In this embodiment, if Figure 4 As shown, the guide protrusions on both sides of the slider 12 are in the shape of inclined strips, and both sides of the end of the slider 12 close to the transmission shaft 4 are also connected to the top plate 14 through elastic connecting components.

[0055] Optionally, both ends of the fixing sleeve 3 are respectively threadedly connected with threaded sleeves 5 , and one end of the slider 12 away from the transmission shaft 4 is exposed from the outside of the fixing sleeve 3 , and the threaded sleeve 5 is used to push the slider 12 to move.

[0056] Specifically, by twisting the threaded sleeve 5 , the slider 12 can be pushed, the position of the slider 12 can be changed, and the magnitude of the torque that can be transmitted by the torque clutch mechanism can be adjusted.

[0057] Optionally, the outer sliding sleeve of the fixed sleeve 3 is provided with two push sleeves 7, and the two push sleeves 7 are respectively provided with multiple receiving grooves 10 at the ends close to each other. The end of the slider 12 away from the transmission shaft 4 is embedded in the receiving groove 10, and a second elastic component 6 is provided between the push sleeve 7 and the threaded sleeve 5.

[0058] Specifically, such as Figure 5 As shown, the end of the slider 12 away from the transmission shaft 4 forms a push block 8, the threaded sleeve 5 transmits the thrust to the push sleeve 7 through the second elastic component 6, and the push sleeve 7 is connected to the push blocks 8 of multiple sliders 12 through multiple receiving grooves 10.

[0059] Optionally, a clamping component 21 is integrally formed in the middle of the fixing sleeve 3 , and the clamping component 21 is used for being clamped by a wrench.

[0060] Specifically, in order to facilitate the twisting of the threaded sleeve 5 and adjust the torque that can be transmitted by the torque clutch mechanism, a clamping component 21 is integrally formed in the middle of the fixed sleeve 3. The clamping component 21 has clamping surfaces arranged in pairs, which are convenient for clamping with a wrench, so that the threaded sleeve 5 can be twisted while clamping the clamping component 21.

[0061] Optionally, a bearing 19 is provided between the transmission shaft 4 and the fixed sleeve 3 , and the inner ring of the bearing 19 is matched with the outer periphery of the transmission shaft 4 through the receiving sleeve 18 .

[0062] Specifically, when the torque clutch mechanism slips, the transmission shaft 4 rotates relative to the fixed sleeve 3 through the bearing 19, reducing the friction between the transmission shaft 4 and the fixed sleeve 3. Since the outer peripheral shape of the transmission shaft 4 is not circular, the inner circle of the receiving sleeve 18 cooperates with the inner ring of the bearing 19, and the inner periphery of the receiving sleeve 18 cooperates with the outer periphery of the transmission shaft 4.

[0063] Optionally, a limiting portion is provided on the inner periphery of the ends of the two threaded sleeves 5 that are away from each other, and a third elastic component 20 is provided between the limiting portion and the receiving sleeve 18 .

[0064] Specifically, the limiting portion presses the receiving sleeve 18 through the third elastic component 20 to prevent the receiving sleeve 18 from moving. The two receiving sleeves 18 are close to each other, and a limiting protrusion can be set on the transmission shaft 4 to facilitate the limiting and removal of the receiving sleeve 18.

[0065] In this embodiment, the first elastic component 13 , the second elastic component 6 and the third elastic component 20 are all springs.

[0066] In summary, when the crystallizer discharging device provided by the present invention is used, the material inlet is connected to the discharging port of the crystallizer. First, the rotation of the threaded sleeve 5 can push the second elastic component 6 and the push sleeve 7, and the push sleeve 7 is used to drive the slider 12 to slide along the guide groove 9. At the same time, due to the cooperation between the guide protrusion and the guide inclined surface, the slider 12 moves in the direction close to the transmission shaft 4, pressing the first elastic component 13, so that the top plate 14 presses the transmission plane of the transmission shaft 4, so that the torque clutch mechanism can transmit the set torque; then the crystallizer discharging device drives the paired stirring and conveying shafts to rotate synchronously in opposite directions through the driving component and the transmission component, thereby realizing the stirring and transmission of the material and discharging the material from the material outlet 27; in this process, if the material is stuck, the torque transmitted by the transmission shaft 4 becomes larger. When the torque is greater than the set torque, the transmission shaft 4 can overcome the elastic force of the first elastic component 13, so that the top plate 14 cannot support the transmission plane. At this time, the two transmission shafts 4 rotate relative to each other and no longer transmit torque, that is, the torque clutch mechanism slips, thereby avoiding damage to the drive motor 22.

[0067] While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
