DETAILED DESCRIPTION

People familiar with the technology can easily understand other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Combined with reference Figure 1-Figure 5 The utility model provides a fluidized drying device for producing foam boxes, including a conveying device 1 for conveying foam boxes. The conveying device 1 adopts a conveyor and realizes periodic intermittent transmission movement. A drying bottom bucket 2 is fixedly mounted on the conveying surface of the conveying device 1. Openings 1 are opened at both ends of the drying bottom bucket 2. The opening 1 located at the top is narrowed in the extension direction of the opening 1 located at the bottom. The opening 1 located at the top can provide an outflow channel for the foam box drying heat source. A supporting rod 3 for supporting the foam box is fixedly connected to the inner side of the drying bottom bucket 2. The supporting rod 3 can be used to support the foam box to be dried. A supporting arm 4 is fixedly connected to the frame of the conveying device 1. A drying top cover 5 is arranged on the inner side of the supporting arm 4. An opening 2 is arranged at the bottom of the drying top cover 5. The size of the opening 2 is similar to that of the drying bottom bucket. 2 and the opening 1 at the top are of the same size. The same size setting can facilitate the docking of the drying top cover 5 and the drying bottom bucket 2 to form a drying collection chamber. With the setting of the opening 1 at the top, the circulation of the drying heat source can be more concentrated. A drying plate 6 is fixedly connected to the inner side of the drying top cover 5, and a ventilation hole is opened on the drying plate 6. The ventilation hole can be used to release the blown-in drying heat source. A telescopic device 7 for vertically lifting the drying top cover 5 is provided on the support arm 4. The telescopic device 7 can adopt a telescopic motor. A fixing seat 8 is fixedly connected to the support arm 4. A drying structure 9 connected to the drying plate 6 is provided on the fixing seat 8. A waste heat recovery component 10 is provided on the drying bottom bucket 2 and the drying top cover 5. The two ends of the waste heat recovery component 10 correspond to the drying bottom bucket 2 and the drying structure 9 respectively.

[0026] A pair of fixed struts 12 are fixedly connected to the bottom of the drying bottom hopper 2, and the fixed struts 12 are fixedly connected to the conveying surface of the conveying device 1. The fixed struts 12 can be used to set up the drying bottom hopper 2 on the conveying surface of the conveying device 1. While ensuring the stable coordinated movement of the drying bottom hopper 2 on the path of the conveying surface, a ventilation area can be reserved at the bottom of the drying bottom hopper 2. In the present application, multiple drying bottom hoppers 2 can be set on the conveying device 1 to be used in sequence to cooperate with the drying top cover 5 for docking.

[0027] A sealing strip 21 is provided on the top of the drying bottom hopper 2, and the sealing strip 21 can be fixed on the drying bottom hopper 2. A sealing groove 1 matched with the sealing strip 21 is provided at the bottom of the drying top cover 5. The drying bottom hopper 2 is movably plugged into and matched with the sealing groove 1 of the drying top cover 5 through the sealing strip 21, so that the sealing effect of the connection can be achieved after the drying top cover 5 and the drying bottom hopper 2 are docked.

[0028] A pair of support blocks 13 are fixedly connected to the sides of the drying top cover 5, and a telescopic rod 14 is fixedly connected to each support block 13, and one end of the telescopic rod 14 facing away from the support block 13 is fixedly connected to the inner top position of the support arm 4. The telescopic rod 14 can achieve a sleeve-type telescopic effect, so that the drying top cover 5 can be more balanced and stable when it is raised and lowered.

[0029] The drying structure 9 includes a blower 91 fixedly connected to the fixed seat 8, a heating component 92 fixedly connected to the air inlet end of the blower 91, and a telescopic stacked pipe 93 connected to the air outlet end of the blower 91. The end of the telescopic stacked pipe 93 facing away from the blower 91 is fixedly passed through the drying top cover 5 and is connected to the drying plate 6. In the present application, the heating component 92 can use an electric heating element for heating; the telescopic stacked pipe 93 can be adaptively telescoped and folded along with the lifting and lowering of the drying top cover 5.

[0030] Specifically, when the conveying device 1 transports one of the drying bottom hoppers 2 with the foam box to the bottom of the drying top cover 5, the telescopic device 7 can be used to drive the drying top cover 5 to move downward until the drying top cover 5 surrounds the foam box on the drying bottom hopper 2. In this way, the heating component 92 can be controlled to heat and the blower 91 can blow air. The blower 91 can send the heated air around the heating component 92 into the drying plate 6 through the telescopic stacked pipes 93. The ventilation holes of the drying plate 6 blow air downward to act on the foam box. The opening at the bottom of the drying bottom hopper 2 provides an outflow channel for the hot air source. In this way, the heat source can be concentrated around the foam box to achieve collection and uniform drying treatment. The conveying device 1 carries the drying bottom hopper 2 to move periodically and intermittently, so that the foam box can be fluidized and dried.

[0031] The waste heat recovery component 10 includes a ventilation square tube 101 fixedly connected to the side of the drying bottom hopper 2 and a ventilation square tube 102 fixedly connected to the side of the drying top cover 5. The bottom of the ventilation square tube 102 is provided with a sealing strip 11, and the top of the ventilation square tube 101 is provided with a sealing groove 2 matched with the sealing strip 11. The ventilation square tube 102 is movably plugged into the sealing groove 2 of the ventilation square tube 101 through the sealing strip 11. The sealing strip 11 can improve the sealing performance of the connection between the ventilation square tube 102 and the ventilation square tube 101. When multiple drying bottom hoppers 2 are provided, the number of ventilation square tubes 101 in this application can be the same as the number of drying bottom hoppers 2, and the number of ventilation square tubes 102 is the same as the number of drying top covers 5.

[0032] Specifically, after the drying top hood 5 and the drying bottom hopper 2 are sealed and docked, the ventilation square tube 102 can be vertically plugged into the ventilation square tube 101 through the sealing strip 11 to achieve docking and sealing. When the hot air source flows out through the opening 1 at the bottom of the drying bottom hopper 2, the air inlet end of the blower 91 is combined with the air suction. In this way, the hot air source at the bottom of the drying bottom hopper 2 can be sent to the air inlet end of the blower 91 through the pipeline formed by the ventilation square tube 102 and the ventilation square tube 101. This can facilitate the preheating of the air at the air inlet end of the blower 91. Combined with the heating of the heating component 92, the efficiency of the stable heating of the heat source used for foam box drying can be improved, and the utilization rate of the heat source can be improved.
