[0002] In industrial production, cooling cylinders are commonly used for material cooling. These cylinders have multiple water channels, effectively reducing the temperature inside or on the surface of the cylinder and providing a more uniform cooling effect. Material is typically conveyed within the cooling cylinder using spiral blades, gradually moving towards the discharge end and cooling during this process.
[0003] Existing multi-channel cooling cylinders typically have a discharge hood at the discharge end for guiding the discharge process. However, the material flow can cause splashing in all directions, resulting in material leakage. If the material gets stuck in the sealing structure, it will affect the rotational stability of the multi-channel cooling cylinder. Utility Model Content

[0016] 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.
[0017] Please see Figure 1-3This utility model provides a technical solution: a multi-groove labyrinth sealed discharge device for a multi-water-channel cooling cylinder, comprising a discharge device body 1 and a multi-water-channel cooling cylinder 5. The discharge device body 1 is located at the discharge end of the multi-water-channel cooling cylinder 5. A discharge cover 2 is provided on the discharge device body 1, covering the outside of the discharge end of the multi-water-channel cooling cylinder 5. An outer sealing element 6 is fixed to the inner ring of the engagement portion between the discharge cover 2 and the multi-water-channel cooling cylinder 5. The outer sealing element 6 has a multi-groove labyrinth structure, and a sealing ring 9 and a sealing filler 8 are respectively engaged in the inner and outer grooves of the outer sealing element 6. The cross-sectional structure of the sealing ring 9 is convex, and the other side of the sealing ring 9 is in close contact with the material collection groove 701. This structure allows the sealing ring 9 to be fastened through the sealing filler 8 and the material collection groove 701, thereby ensuring... To ensure the sealing performance of the multi-channel cooling cylinder 5 and the main body 1 of the discharge device, a discharge end plate 4 is fixed to the inner side of the discharge end of the multi-channel cooling cylinder 5, and discharge holes 401 are evenly spaced on the side of the discharge end plate 4. An inner sealing element 7 is fixedly fitted around the outer ring of the multi-channel cooling cylinder 5. Inner and outer cylinder annular sealing plates 501 are fixed to the outer side of the discharge end of the multi-channel cooling cylinder 5 by welding, and the inner and outer cylinder annular sealing plates 501 are bolted to the side of the inner sealing element 7. The sealing filler 8 is attached to the outer side of the inner and outer cylinder annular sealing plates 501. This structure, through the setting of the inner and outer cylinder annular sealing plates 501, can make the inner and outer cylinder annular sealing plates 501 and the end of the multi-channel cooling cylinder 5 form a stepped structure, so as to ensure the reliable positioning of the sealing filler 8. The sealing filler 8 can prevent external dust from entering. The inner seal 7 is sealed within a sealed structure, and a material catcher 701 is fixed to the outside of the inner seal 7. The cross-sectional structure of the inner seal 7 is L-shaped, and the outer seal 6 and the sealing packing 8 are also engaged. In this structure, the inner seal 7 is fixed to the outside of the multi-channel cooling cylinder 5 by bolts, allowing the inner seal 7 to rotate relative to the outer seal 6. Furthermore, a spiral blade 702 is fixed to the inner side of the material catcher 701. The groove of the material catcher 701 has a sloping structure, and the material catcher 701 and the outer seal 6 are engaged by a ball bearing structure. The material catcher 701 is also sealed to the discharge hood 2. This structure allows the material catcher 701 to quickly discharge material caught by the sloping surface. When the material leaks into the gap between the discharge hood 2 and the multi-channel cooling cylinder 5, it allows… The material trough 701 holds the material, and as it rotates with the multi-channel cooling cylinder 5, the material, when it reaches the upper part, falls onto the inner seal 7 under gravity. The inner seal 7, through rotation, allows the material to be discharged into the discharge hood 2 via the spiral blades 702. The spiral direction of the spiral blades 702 is designed to facilitate material discharge. As the material trough 701 rotates with the multi-channel cooling cylinder 5, the ball bearing structure embedded in the outer seal 6 reduces drag and ensures the reliability of the material trough 701 structure. The inner seal 7 rotates synchronously with the multi-channel cooling cylinder 5, causing the material trough 701 and the spiral blades 702 to rotate synchronously. A discharge hopper 202 is welded and fixed to the bottom of the discharge hood 2, and a cooling water pipe 3 runs through the side of the discharge hood 2.Furthermore, the discharge hood 2 and the cooling water pipe 3 are tightly fitted with a built-in shock-absorbing sealing ring 201. Material entering the discharge hood 2 can be discharged through the bottom discharge hopper 202. The shock-absorbing sealing ring 201 provides a shock-absorbing and protective structure between the discharge hood 2 and the cooling water pipe 3. Simultaneously, the discharge hood 2 and the cooling water pipe 3 are detachable, facilitating pipe maintenance. Since material will not leak out, damage to the sealing structure is avoided, preventing exchange between the internal and external environments, and ensuring stable operation of the multi-water cooling cylinder 5.
[0018] Working principle: When using the multi-channel cooling cylinder multi-groove labyrinth sealed discharge device, the material inside the multi-channel cooling cylinder 5 is gradually pushed forward and cooled before moving to one end of the discharge device body 1. The multi-channel cooling cylinder 5 rotates, causing the material to be discharged from the discharge hole 401 on the discharge end plate 4 into the discharge hood 2, and then discharged from the discharge hopper 202. The discharge device body 1 and the multi-channel cooling cylinder 5 are sealed by a sealing packing 8 to prevent external dust from entering the sealing structure. The inner and outer cylinder annular sealing plates 501 fix the sealing packing 8. During the discharge process, any leakage of material... The material is caught in the material trough 701. As the inner seal 7 rotates synchronously with the multi-channel cooling cylinder 5, the material moves in a circular motion with the material trough 701 until it falls out of the trough 701. At this time, the spiral blade 702 pushes the material that has been caught after leakage into the discharge hood 2. The discharge hood 2 and the cooling water pipe 3 are sealed and protected by the shock-absorbing sealing ring 201, which also has a shock-absorbing function. The multi-groove structure of the outer seal 6 ensures that the sealing ring 9 and the sealing filler 8 are stably positioned, while ensuring the sealing effect, thus completing a series of tasks.
[0019] Although the present invention 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 invention should be included within the protection scope of the present invention.
