[0028] Specifically, the utility model sets an auxiliary push component, uses the electric slide rail slide 16 to provide a reciprocating drive source, and with the assistance of the reinforced side frame 19 and the reinforced frame 20, the placement box 4 can swing itself during the up and down reciprocating movement, so that the fire-resistant PVC particles in the placement box 4 can be continuously turned over, so that the fire-resistant PVC particles can fully contact the hot air in the placement box 4, and thus effectively avoid the fire-resistant PVC particles from being unable to uniformly contact the heat due to accumulation, thereby improving the drying effect of the fire-resistant PVC particles and avoiding uneven drying.
[0029] A discharge frame 9 is embedded at the bottom of the left side of the placement box 4, one end of which is connected to the left side partition net 6. A sealing seat 10 is inserted in the discharge frame 9. The sealing seat 10 is symmetrically slidable front and back with an L-shaped locking plate 11. One end of the L-shaped locking plate 11 passes through the sealing seat 10 and the discharge frame 9 in sequence and extends outward. A horizontal plate is symmetrically fixed to the left side of the sealing seat 10, and a spring 15 is fixed on the side where the horizontal plate and the L-shaped locking plate 11 are close to each other.
[0030] Specifically, the spring 15 and the L-shaped locking plate 11 can quickly form a locking structure for the sealing seat 10, so as to freely control the opening and closing state of the discharge frame 9, facilitate the rapid discharge of the dried refractory PVC particles, and effectively avoid the easy residue of refractory PVC particles.
[0031] A fixing belt 12 is fixed to the left side of the L-shaped locking plates 11 that are close to each other.
[0032] Specifically, the design of the fixing belt 12 facilitates the synchronous pulling of the two sets of L-shaped locking plates 11, thereby improving the efficiency of disassembling the sealing seat 10 and facilitating the rapid discharge of the fire-resistant PVC particles.

[0035] There is a distance between the end of the reinforcement side frame 19 away from the bottom frame 1 and the placement box 4 .
[0036] Specifically, the spacing design can effectively prevent the reinforced side frame 19 from contacting the placement box 4, affecting the normal use of the reinforced side frame 19, and avoid excessive wear on the reinforced side frame 19, making it easy to be damaged.
[0037] A plurality of fixed pipes 7 communicating with the upper partition net 6 are sequentially embedded on the right side of the top of the placement box 4 along the front-to-back direction, and each group of fixed pipes 7 is provided with an auxiliary electromagnetic valve 8.
[0038] Specifically, the design of the fixed pipe 7 and the auxiliary electromagnetic valve 8 can facilitate the addition of materials into the storage box 4 on the one hand, and can regularly relieve the pressure of the storage box 4 on the other hand to ensure that the storage box 4 can operate stably.
[0039] The specific usage process is as follows: the user pours the fire-resistant PVC particles that need to be dried into the placement box 4 through the fixed pipe 7. After the pouring is completed, the fire-resistant PVC particles will not be filled, and a surplus will be left to reserve space for the turning of the fire-resistant PVC particles. At this time, the user closes the auxiliary solenoid valve 8, and turns on the heater 21 and the air pump 22. At this time, the air pump 22 transmits the heat generated by the heater 21 to the first connecting rack 24 and the second connecting rack 25 through the telescopic tube 23, and then transmits it to the multiple groups of placement slots 5, and sprays it in multiple directions in the placement box 4, so that the heat inside the placement box 4 can be quickly and evenly diffused, so as to further improve the drying uniformity. At the same time, the user turns on the electric slide rail slide 16 through the controller, and presets the motor on it. The number of reciprocating revolutions can drive the positioning slider 18 to move up and down through its upper slide, and then, with the assistance of the support frame 3, drive the placement box 4 to move up and down, and under the restriction of the reinforced side frame 19, drive the reinforcement frame 20 and the placement box 4 to swing synchronously when moving up and down, so that the fire-resistant PVC particles in the placement box 4 can be continuously turned over, so that the fire-resistant PVC particles can fully contact with the hot air in the placement box 4, thereby accelerating the drying efficiency. After the drying is completed, the user only needs to pull the fixing belt 12 to drive the L-shaped locking plate 11 to move inward and disengage from the discharge frame 9, thereby releasing the locking state of the sealing seat 10. At this time, the user can pull the sealing seat 10 outward to remove it from the discharge frame 9 and release the lock of the discharge frame 9. The utility model provides an auxiliary pushing component, utilizes the electric slide rail slide 16 to provide a reciprocating driving source, and with the assistance of the reinforced side frame 19 and the reinforced frame 20, the placement box 4 can swing itself during the up and down reciprocating movement, thereby continuously turning the refractory PVC particles in the placement box 4, so that the refractory PVC particles can fully contact with the hot air in the placement box 4, thereby effectively avoiding the refractory PVC particles from being easily unable to contact the heat evenly due to accumulation, improving the drying effect of the refractory PVC particles, and avoiding the occurrence of uneven drying; the spring 15 and the L-shaped locking plate 11 can quickly form a locking structure for the sealing seat 10, so as to close the discharge frame 9 The opening and closing states can be freely controlled, which is convenient for quickly discharging the dried fire-resistant PVC particles and can effectively prevent the fire-resistant PVC particles from being easily left behind; the design of the fixing belt 12 facilitates the synchronous pulling of the two sets of L-shaped locking plates 11, thereby improving the disassembly efficiency of the sealing seat 10 and facilitating the rapid discharge of the fire-resistant PVC particles; the design of the anti-shift rod 13, in conjunction with the limiting position of the blocking ring 14, can limit the moving distance of the L-shaped locking plate 11, preventing the L-shaped locking plate 11 from easily separating from the sealing seat 10, thereby improving the moving stability of the L-shaped locking plate 11; the design of the spacing can effectively prevent the reinforced side frame 19 from contacting the placement box 4, affecting the normal use of the reinforced side frame 19, and avoiding excessive wear on the reinforced side frame 19, making it easy to damage;The design of the fixed pipe 7 and the auxiliary solenoid valve 8 can facilitate the addition of materials into the storage box 4 on the one hand, and can also regularly relieve the pressure of the storage box 4 to ensure the stable operation of the storage box 4 on the other hand.
