[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figures 1 to 5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0015] like Figures 1 to 5 As shown: Example

[0016] A foam recycling sealing mechanism for a refrigerator dismantling line includes a crusher 3 mounted on a support, with an inlet 1 at the upper end and an outlet at the lower end; a conveyor belt 4 positioned below the crusher 3 to receive the crushed material, a suction hood 5 above the conveyor belt 4 connected to a conveying pipe 6 connected to a centrifugal fan 7; and a sealing mechanism including a discharge cylinder 13 connected to the crusher 3 at the upper end and the conveyor belt 4 at the lower end, with a sealing plate 12 positioned between the crusher 3 and the suction hood 5.

[0017] In this embodiment, the recycling of waste refrigerators mainly involves the recovery of foam, iron materials, and non-ferrous metals containing copper and aluminum. Because foam is lightweight, it is prone to dissipation during recycling; therefore, a sealing mechanism for the foam is crucial. In this design, considering the large amount of foam in the mixture after crushing in the crusher 3, sealing is required after the foam leaves the crusher 3. Based on the principle of foam's light weight, a suction method is used to remove the foam. Specifically, a suction hood 5 is installed on the conveyor belt 4, connected to a conveying pipe 6, which in turn is connected to a centrifugal fan 7. The output of the centrifugal fan 7 can be connected via a pipe to a foam separation chamber, such as a diaphragm chamber.

[0018] To achieve a seal, a feed cylinder 13 is connected to the lower end of the crusher 3, and a conveyor belt 4 is connected to the lower end of the feed cylinder 13. A sealing plate 12 is then installed between the crusher 3 and the suction hood 5 to prevent foam from escaping from the position between the suction hood 5 and the crusher 3. Example

[0019] The lower end of the inhalation hood 5 has a flared structure and is fixed to the outer shell of the conveyor belt 4 by bolts. The lower end of the inhalation hood 5 is provided with a support frame 8, the support frame 8 is connected to a roller shaft 9, and a baffle 10 is provided on the roller shaft 9.

[0020] Unlike the above embodiments, in this embodiment, the suction hood 5 adopts a flared structure, and its lower end is fixed to the outer shell of the conveyor belt 4 by bolts. Since there is a gap between the suction hood 5 and the conveyor belt 4, it is necessary to consider that no foam can escape at this gap. Therefore, a support frame 8 is provided on the lower end surface at this gap. The support frame 8 is connected to a roller 9, which can rotate. A baffle 10 is provided on the roller 9. After being driven by the wind on the outside of the baffle 10, it can effectively prevent foam from escaping outward. Example

[0021] There are four baffles 10. The baffles 10 are parallel to the axis of the roller shaft 9 and are fixedly connected to the outer side of the roller shaft 9. The baffles 10 evenly divide the outer side of the roller shaft 9. The roller shaft 9 is connected to the support frame 8 through bearings.

[0022] Unlike the above embodiments, in this embodiment, the baffle 10 is a plate-shaped structure, and the number is preferably four, which are evenly arranged on the outer side of the roller 9. Example

[0023] The sealing plate 12 is connected to a sliding groove 11, which is provided on the outer side of the crusher 3 and the outer side of the suction hood 5. The lower end face of the sealing plate 12 contacts the upper end face of the outer shell of the conveyor belt 4, and the sealing plate 12 is controlled by pulling.

[0024] Unlike the above embodiments, in this embodiment, the sealing plate 12 is detachable. Slide grooves 11 are provided on the outer side of the crusher 3 and the outer side of the suction hood 5. The sealing plate 12 can be locked in the slot. The advantage of designing the sealing plate 12 as detachable is that it is convenient to repair internal blockages. Example

[0025] The feeding cylinder 13 is a flexible cloth cylinder structure used to seal the area between the feeding port at the lower end of the crusher 3 and the head of the lower end of the conveyor belt 4.

[0026] Unlike the above embodiments, in this embodiment, the feeding cylinder 13 is made of a soft material, which facilitates the connection between the crusher 3 and the conveyor belt 4, and also prevents the foam from escaping during the falling process, effectively sealing the foam.

[0027] The working method (or working principle) of this utility model: In operation, this technology features an inlet 1 at the top of the crusher 3 for feeding shredded waste refrigerator materials. The shredded materials, being large pieces, are fed into the crusher 3 for further crushing. The bottom of the crusher 3 is the outlet, connected to a feed cylinder 13. After crushing, the material passes through the feed cylinder 13 to the bottom of the conveyor belt 4, where it is gradually transported upwards. The material contains foam; to prevent it from scattering, a sealing process is required after the conveyor belt carries the material away from the feed cylinder 13. A chute 11 is installed between the crusher 3 and the suction hood 5, connecting to a sealing plate 12 for sealing. The suction hood 5 is then connected to a centrifugal fan 7 via a conveying pipe 6, which helps to recover the foam through air extraction. Then there is also a gap between the lower outer end of the suction hood 5 and the conveyor belt 4. A baffle 10 is installed in this gap. When the baffle 10 rotates, the upper end contacts the lower end of the suction hood 5. Since the space below the baffle 10 is large, the centrifugal fan 7 blows the baffle 10 to rotate, which can effectively prevent the foam from escaping outward.

[0028] In this utility model, unless otherwise explicitly specified and limited, for example, it can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components or an interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
