Description

Technical Field

[0001] This invention relates to the field of cheese production technology, and in particular to an anti-clogging discharge mechanism and a cheese production tank containing the mechanism. Background Technology

[0002] In cheese production, processes such as fermentation, curdling, mixing, whey removal, and finished product discharge are typically completed within cheese production tanks. The smoothness of the discharge process directly impacts production efficiency, product quality, and production continuity. Cheese materials are characterized by high viscosity and high solids content, and are prone to bridging or accumulating near the discharge port, leading to blockages. Currently, existing cheese production tanks typically have a vertically rotating shaft inside the tank. Multiple sets of stirring rods are fixedly fitted around the shaft from top to bottom. The stirring rods rotate with the shaft to mix the materials inside the tank, ensuring uniform blending. During the discharge stage, the discharge port at the bottom of the tank is opened, and the shaft and stirring rods continue to rotate. The rotational force of the stirring rods propels the cheese materials towards the discharge port, accelerating their discharge.

[0003] While the aforementioned discharge methods can improve discharge efficiency to some extent and reduce some clogging issues compared to production tanks without agitation structures, they still have many shortcomings and disadvantages in practical applications. They struggle to meet the high-efficiency and stable discharge requirements of high-viscosity cheese materials. Cheese materials tend to form stable bridging structures above the discharge port due to the mutual support of solid particles. However, the agitators in these methods are mostly fixed horizontally or at an angle, and their rotation only agitates the material as a whole within the tank, failing to target the critical area above the discharge port. For the existing bridging structure, the rotational impact of the agitator is dispersed, making it difficult to effectively break up the bridging. Furthermore, a gap inevitably exists between the agitator and the inner wall of the discharge port, where material easily accumulates and stagnates. As the discharge process progresses, the accumulated material increases, eventually leading to blockage of the discharge port. This necessitates manual shutdown for cleaning, severely impacting production continuity and increasing hygiene risks and labor costs. Summary of the Invention

[0004] Therefore, it is necessary to provide an anti-blocking discharge mechanism that can prevent material blockage during discharge and a cheese production tank containing such mechanism to address the above-mentioned technical problems.

The pressure plate is fixedly installed at the bottom of the movable rod, located above the discharge port; A lifting assembly, located inside the rotating cylinder, is used to drive the movable rod to move up and down reciprocally.

[0011] In one embodiment, a rotating rod is rotatably mounted inside the pressure plate, and a cam is fixedly sleeved on the outside of the rotating rod. The protrusions on both sides of the cam movably abut against the movable plates on both sides.

[0012] In one embodiment, a vertical rod is movably installed inside the movable rod, the bottom of the vertical rod movably passes through the top of the pressure plate, and the end is located inside the slot. The end of the vertical rod is connected to the top of the rotating rod by a belt drive.

[0013] In one embodiment, the movable rod has a groove, the top of the vertical rod is located inside the groove, a horizontal rod is rotatably installed in the groove, one end of the horizontal rod movably passes through the inner wall of the groove and a transmission gear is fixedly installed at the end, the end of the horizontal rod away from the gear is connected to the vertical rod through a bevel gear transmission, and a rack is fixedly installed on the inner wall of the rotating cylinder, and the transmission gear meshes with the rack for transmission.

A movable plate is movably arranged in the movable groove, and multiple inclined grooves are axially symmetrically arranged on both sides of the movable plate.

[0026] The following is combined Figures 1-10 This invention describes an anti-clogging discharge mechanism and a cheese production tank containing the mechanism.

[0027] like Figures 1-6 As shown, in one embodiment, an anti-clogging discharge mechanism includes a tank 1 and a rotating cylinder 2 rotatably installed inside the tank 1, and further includes: The discharge port 101 is located at the bottom of the tank body 1, below the rotating cylinder 2; Multiple fixed rings 3 are linearly arranged from top to bottom and fixedly sleeved on the outside of the rotating cylinder 2. The stirring rod 4 is fixedly installed in a ring array on the outside of the fixing ring 3; The fixed rod 5 is movably installed inside the rotating cylinder 2, and its top is fixedly connected to the inner wall of the top of the tank 1. Its diameter is smaller than the inner diameter of the rotating cylinder 2. The movable rod 6 extends through the bottom of the rotating cylinder 2 and moves up and down relative to the rotating cylinder 2. The pressure plate 7 is fixedly installed at the bottom of the movable rod 6, located above the discharge port 101; The lifting assembly 8 is located inside the rotating cylinder 2 and is used to drive the movable rod 6 to move up and down reciprocally.

[0028] Specifically, the tank 1 contains cheese. When the motor of the rotating drum 2 is started, the rotating drum 2 rotates, causing the fixed ring 3 and the stirring rod 4 to rotate synchronously. At the same time, the cover plate at the discharge port 101 at the bottom of the tank 1 is opened. The rotation of the stirring rod 4 can also accelerate the movement of the cheese toward the discharge port 101, speeding up the discharge. During the rotation of the rotating drum 2, the fixed rod 5 remains stationary. The rotation of the rotating drum 2 will drive the movable rod 6 and the pressure plate 7 to rotate synchronously. During this process, the lifting component 8 drives the movable rod 6 to move up and down relative to the rotating drum 2. The movement of the movable rod 6 will drive the pressure plate 7 to move up and down. The descent of the pressure plate 7 will accelerate the movement of the cheese toward the discharge port 101, increasing the discharge speed of the cheese.

[0029] See Figures 4-6 As shown, in this embodiment, the lifting assembly 8 includes a limiting rod 81, which is fixedly installed on the end of the movable rod 6 that is close to the fixed rod 5. The fixed rod 5 has a curved groove 82, and the end of the limiting rod 81 away from the movable rod 6 slides and fits against the curved groove 82.

[0030] Specifically, during the rotation of the rotating cylinder 2, the movable rod 6, the limiting rod 81, and the pressure plate 7 rotate synchronously together. The limiting rod 81 rotates around the fixed rod 5, and the fixed rod 5 has a curved groove 82. One end of the limiting rod 81 rotates along the curved groove 82, thereby enabling the limiting rod 81, the movable rod 6, and the pressure plate 7 to reciprocate and rise during rotation. The rotation of the stirring rod 4 keeps the material in a loose state, preventing clumping. The rising and falling of the pressure plate 7 forms a periodic compression of the material, pushing the material to flow rapidly towards the discharge port 101. The superposition of rotation and rising and falling creates complex shear forces and flow paths inside the material, effectively reducing viscosity and improving overall fluidity. Secondly, during the rotation and rising and falling process, the pressure plate 7 will periodically compress and release the material. The pressure plate 7 descends → compresses the material → the material is pushed towards the discharge port 101. The pressure plate 7 rises → the space increases → the material is quickly replenished. It descends again → compresses again. This cyclical action is similar to the working principle of a "mechanical pump," which has a significant pumping effect on high-viscosity cheese materials and can significantly improve the discharge speed.

[0031] See Figures 4-6 As shown, in this embodiment, the movable rod 6 is fixedly sleeved on the outer side of the inner part of the rotating cylinder 2 with a movable frame 83, and the bottom of the movable frame 83 is fixedly connected to the inner wall of the bottom of the rotating cylinder 2 by a positioning spring 84.

[0032] Specifically, the moving rod 6 moves up and down, which drives the moving frame 83 to move synchronously. During the movement of the moving frame 83, the positioning spring 84 will deform, and the positioning spring 84 can ensure the stability of the moving frame 83 during the up and down movement.

[0033] See Figure 3As shown, in this embodiment, the pressure plate 7 has multiple through holes 71, which penetrate the upper and lower side walls of the pressure plate 7.

[0034] Specifically, during the cheese discharge process, due to the high viscosity, high solid content, and tendency to clump and bridge of the material, the traditional solid pressure plate 7 is prone to problems such as material accumulation, negative pressure, and backflow during the lifting and lowering process. However, after opening through holes 71 on the pressure plate 7, these situations can be significantly improved. When the pressure plate 7 rises, air or material can be replenished to the lower part through the through holes 71, effectively avoiding the generation of negative pressure, and the material can flow continuously and stably to the discharge port 101. Secondly, when the pressure plate 7 rises, the material above can fall quickly directly through the through holes 71, and the area above the discharge port 101 is always kept in a "full material state", which significantly improves the discharge speed.

[0035] See Figures 6-9 As shown, in this embodiment, the pressure plate 7 has a slot 72 inside, and movable plates 9 are axially symmetrically arranged on both sides of the slot 72. The movable plates 9 have round holes 91, which are movably aligned with the through holes 71.

[0036] Specifically, when the circular hole 91 on the movable plate 9 is aligned with the through hole 71, the through hole 71 is in an open state. Along the movable plates 9 at both ends of the groove 72, the part of the movable plate 9 without the circular hole 91 is aligned with the through hole 71, and the through hole 71 is in a covered state. During the up and down movement of the pressure plate 7, the through hole 71 is alternately opened and closed. When the through hole 71 is closed, the pressure plate 7 forms a squeezing surface, and the material is pressed downward. When the through hole 71 is open, the pressure is released, and the material is quickly replenished. This pulse action of "squeezing-releasing-re-squeezing" can significantly improve the material flowability.

[0037] See Figures 6-9 As shown, in this embodiment, a plurality of fixed cylinders 10 are arranged in a horizontal linear array on one side of the movable plate 9, and a plurality of insert rods 11 are fixedly installed in a horizontal linear array on the other side of the movable plate 9. The end of the insert rod 11 away from the movable plate 9 on the same side is slidably connected to the fixed cylinder 10, and the end of the insert rod 11 is fixedly connected to the inner wall of the fixed cylinder 10 by a return spring 12.

[0038] Specifically, as the movable plates 9 move closer to or further away from each other, the insert rod 11 moves relative to the fixed cylinder 10. When the insert rod 11 moves away from the fixed cylinder 10, it stretches the return spring 12. When the insert rod 11 moves inward relative to the fixed cylinder 10, the return spring 12 returns to its original state. The return spring 12 can ensure the stability of the movable plates 9 on both sides during their movement within the slot 72.

[0039] See Figures 6-9As shown, in this embodiment, a rotating rod 13 is rotatably installed inside the pressure plate 7, and a cam 14 is fixedly sleeved on the outside of the rotating rod 13. The protrusions on both sides of the cam 14 are in contact with the movable plates 9 on both sides.

[0040] Specifically, the rotation of the rotating rod 13 will drive the cam 14 to rotate. When the protrusions at both ends of the cam 14 abut against the movable plate 9, the movable plates 9 on both sides move away from each other, and the return spring 12 is in a stretched state. At this time, the round hole 91 is aligned with the through hole 71. When the rotating rod 13 rotates, the protrusions of the cam 14 will not abut against the movable plate 9. Under the action of the return spring 12, the movable plates 9 on both sides will be pulled to move towards the center, blocking the through hole 71.

[0041] See Figures 6-9 As shown, in this embodiment, a vertical rod 15 is movably installed inside the movable rod 6. The bottom of the vertical rod 15 movably passes through the top of the pressure plate 7, and the end is located inside the slot 72. The end of the vertical rod 15 is connected to the top of the rotating rod 13 by a belt 16.

[0042] Specifically, the rotation of the vertical rod 15 drives the rotating rod 13 to rotate through the transmission of the belt 16. The rotation of the rotating rod 13 drives the cam 14 to rotate, thereby making the two movable plates 9 move away from each other or closer together, so that the through hole 71 is in an alternating open or closed state, which can increase the speed of cheese discharge.

[0043] See Figure 5 , Figure 6 and Figure 9 As shown, in this embodiment, the movable rod 6 has a groove 61, the top of the vertical rod 15 is located inside the groove 61, and a horizontal rod 17 is rotatably installed in the groove 61. One end of the horizontal rod 17 movably passes through the inner wall of the groove 61 and a transmission gear 18 is fixedly installed at the end. The end of the horizontal rod 17 away from the gear is connected to the vertical rod 15 through a bevel gear 19. A rack 20 is fixedly installed on the inner wall of the rotating cylinder 2, and the transmission gear 18 meshes with the rack 20 for transmission.

[0044] Specifically, during the reciprocating movement of the movable rod 6, the transmission gear 18 meshes with the rack 20. The rotation of the transmission gear 18 drives the horizontal rod 17 to rotate within the groove 61. The horizontal rod 17 and the vertical rod 15 are driven by the meshing of the bevel gear 19, so the vertical rod 15 also rotates. The rotation of the vertical rod 15 drives the rotating rod 13 and the cam 14 to rotate through the transmission of the belt 16, causing the movable plate 9 to move, thus achieving the effect of alternating opening and closing of the through hole 71.

[0045] See Figures 3-4 , Figure 7 and Figure 10As shown, in this embodiment, the stirring rod 4 has a movable groove 41 in the center, and multiple crushing rods 21 are axially symmetrically arranged on both sides of the movable groove 41. A movable plate 22 is movably arranged in the movable groove 41, and multiple inclined grooves 221 are axially symmetrically arranged on both sides of the movable plate 22. One end of the crushing rod 21 is slidably embedded in the surface of the movable plate 22 and the inclined grooves 221.

[0046] Specifically, the rotation of the stirring rod 4 will drive the crushing rod 21 to rotate synchronously. During the rotation, the moving plate 22 moves laterally back and forth relative to the movable groove 41. During the movement of the moving plate 22, the inclined groove 221 will come into contact with the crushing rod 21. When one end of the crushing rod 21 moves from the lower part to the higher part relative to the inclined groove 221, the crushing rod 21 moves outward relative to the stirring rod 4. Similarly, when one end of the crushing rod 21 moves from the higher part to the lower part relative to the inclined groove 221, the crushing rod 21 moves inward. The rotation of the stirring rod 4 can only provide "shearing force" and "centrifugal force", but cannot penetrate into the material to "crush" and "loosen". The crushing rod 21 extends and retracts laterally while the stirring rod 4 rotates, which is equivalent to continuously "prick + stir + cut" inside the material. This can significantly improve the fluidity and looseness of the material, cut and crush large pieces of cheese curd, make the material particle size more uniform, and avoid large particles forming bridges at the discharge port 101.

[0047] See Figure 7 and Figure 10 As shown, in this embodiment, a round rod 23 is fixedly provided on one side of the moving plate 22. One end of the round rod 23 movably passes through the stirring rod 4 and the side wall of the rotating cylinder 2. Multiple rings 24 are arranged linearly from top to bottom on the outer side of the fixed rod 5. Multiple arc-shaped grooves 241 are arranged in annular array on the rings 24. The end of the round rod 23 away from the moving plate 22 is slidably embedded in the surface of the rings 24 and the arc-shaped grooves 241.

[0048] Specifically, during the rotation of the rotating drum 2, the round rod 23 also rotates around the fixed rod 5. One end of the round rod 23 rotates along the arc groove 241 opened in the ring 24. When the round rod 23 moves higher relative to the arc groove 241, the round rod 23 moves away from the fixed rod 5, driving the moving plate 22 to move in the movable groove 41, causing the inclined groove 221 to contact the crushing rod 21, so that the crushing rod 21 moves outward from the stirring rod 4. Similarly, when the round rod 23 moves lower relative to the arc groove 241, the round rod 23 drives the moving plate 22 to move in the opposite direction, and the crushing rod 21 returns to the initial position, which can realize the lateral reciprocating movement of the crushing rod 21 and reduce the probability of material bridging.

[0049] In this embodiment, a cheese production tank includes the aforementioned anti-clogging discharge mechanism.

[0050] Specifically, a cheese production tank, in addition to the aforementioned anti-clogging discharge mechanism, usually has a receiving device below the discharge port 101 to catch the discharged cheese.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
