Description

Technical Field

[0001] The utility model belongs to the technical field of flame retardant processing, and specifically refers to a dryer for flame retardant processing. Background Art

[0002] A flame retardant is a functional additive that imparts flame retardancy to flammable polymers. The flame retardant exerts its flame retardant effect through several mechanisms and is mainly applied in the fields of transportation, electronic and electrical equipment, furniture, and building materials. A dryer is required for processing the flame retardant.

[0003] In the prior art, such as a dryer for flame retardant processing with the publication number of CN221122922U, the rotation of the drum driven by a motor can drive the flame retardant inside the drum to rotate synchronously. As the flame retardant rotates, the heating plate can heat the flame retardant more evenly, thereby improving the heating and drying effect. After drying, the flame retardant is discharged through the discharge port for convenient storage.

[0004] However, the above-mentioned and other typical prior arts still have certain problems when in use: it is not convenient to discharge the flame retardant after drying and the discharge efficiency is low. Summary of the Utility Model

[0005] In view of the above situation, to overcome the defects of the prior art, the utility model provides a dryer for flame retardant processing, which effectively solves the problem of inconvenient discharge of the flame retardant after drying.

[0006] To achieve the above functions, the technical solution adopted by the utility model is as follows: A dryer for flame retardant processing includes a bottom plate, a drying cylinder, a support adjustment mechanism, and a sealing cover plate.

[0007] Preferably, the pushing mechanism includes an electric push rod, a limiting groove and a roller. The movable end of the electric push rod is fixed on the limiting cross plate, and the fixed end of the electric push rod is fixed on the limiting frame. The limiting groove is arranged on the fixed side plate. Two groups of external connection blocks one and external connection blocks two are symmetrically arranged on the upper and lower outer side walls of the sealing cover plate. Two groups of top frames are symmetrically fixed on the limiting cross plate. A connecting shaft is rotatably arranged on the external connection block one. A roller is rotatably arranged at one end of the connecting shaft away from the external connection block one. The roller can move relative to the fixed side plate and the limiting chute. A connecting rod one is rotatably arranged on the connecting shaft. One end of the connecting rod one away from the external connection block one is rotatably arranged on the top frame. A connecting rod two is rotatably arranged on the external connection block two. One end of the connecting rod two away from the external connection block two is rotatably arranged on the top frame.

[0008] Preferably, the connecting rod one and the connecting rod two are of the same length.

[0009] Preferably, both the top frame and the limiting frame are arranged in a U-shaped structure.

[0010] Preferably, the support and adjustment mechanism includes a fixed block, a pushing cylinder, a bottom fixing frame, a connecting plate and a fixed support plate. The fixed support plate is fixed on the bottom plate. The top end of the connecting plate is fixed under the bottom wall of one end of the drying cylinder close to the sealing cover plate.

[0021] Such as Figures 1-4As shown in the figure, a dryer for flame retardant processing proposed by the present utility model includes a bottom plate 1, a drying cylinder 2, a support adjustment mechanism 6 and a sealing cover plate 5. The support adjustment mechanism 6 is arranged on the bottom plate 1, the drying cylinder 2 is arranged on the support adjustment mechanism 6, a heating plate 3 is embedded on the inner side wall of the drying cylinder 2, and a stirring assembly 4 is also arranged in the drying cylinder 2 to evenly distribute the flame retardant and heat it evenly. The sealing cover plate 5 is hermetically covered at one end inside the drying cylinder 2. Two groups of fixed side plates 7 arranged symmetrically are fixed on the outer side wall of the drying cylinder 2 near the sealing cover plate 5. Two groups of L-shaped connecting frames 11 arranged in parallel are fixed on the outer side wall of the fixed side plates 7. A limiting frame 12 is fixed on the connecting frame 11. A limiting chute 8 is arranged on the side wall of the limiting frame 12. A limiting cross plate 9 is slidably arranged on the limiting chute 8. A pushing mechanism 10 connected to the sealing cover plate 5 is arranged on the limiting frame 12 and the limiting cross plate 9 to facilitate the sealing and opening of the sealing cover plate 5. A pressure valve 29 is arranged on the sealing cover plate 5 to automatically relieve pressure inside the drying cylinder 2.

[0022] As Figure 1 、 2 shown, the pushing mechanism 10 includes an electric push rod 15, a limiting groove 13 and a roller 14. The movable end of the electric push rod 15 is fixed on the limiting cross plate 9, and the fixed end of the electric push rod 15 is fixed on the limiting frame 12. The limiting groove 13 is arranged on the fixed side plate 7. Two groups of external connection blocks one 17 and external connection blocks two 18 are symmetrically arranged up and down on the outer side wall of the sealing cover plate 5. Two groups of top frames 30 are symmetrically fixed on the limiting cross plate 9. A connecting shaft 16 is rotatably arranged on the external connection block one 17. A roller 14 is rotatably arranged at one end of the connecting shaft 16 away from the external connection block one 17. The roller 14 can move relative to the fixed side plate 7 and the limiting chute 8. A connecting rod one 19 is rotatably arranged on the connecting shaft 16. One end of the connecting rod one 19 away from the external connection block one 17 is rotatably arranged on the top frame 30. A connecting rod two 20 is rotatably arranged on the external connection block two 18. One end of the connecting rod two 20 away from the external connection block two 18 is rotatably arranged on the top frame 30. When the electric push rod 15 retracts, it drives the limiting cross plate 9 to slide on the limiting chute 8. The movement of the limiting cross plate 9 drives the top frame 30 to move. Since the position heights of the limiting cross plate 9 and the top frame 30 are fixed, according to the parallelogram principle, the movement of the top frame 30 drives the connecting rod one 19 and the connecting rod two 20 to rotate. The rotation of the connecting rod one 19 and the connecting rod two 20 causes the external connection block one 17, the external connection block two 18 and the connecting shaft 16 to move outwards, thereby driving the sealing cover plate 5 to move out of the drying cylinder 2. After the connecting shaft 16 drives the roller 14 to move out of the limiting groove 13, it moves upwards along the fixed side plate 7. After moving the sealing cover plate 5 out, it moves upwards to open one end of the drying cylinder 2, facilitating the discharge of the flame retardant after drying. The lengths of the connecting rod one 19 and the connecting rod two 20 are the same, and both the top frame 30 and the limiting frame 12 are arranged in a U-shaped structure.

[0023] As Figure 2 、 3, as shown in FIG. 4, the support adjustment mechanism 6 includes a fixed block 21, a pushing cylinder 22, a bottom fixing frame 23, a connecting plate 25 and a fixed support plate 24. The fixed support plate 24 is fixed on the bottom plate 1. The top end of the connecting plate 25 is fixed under the bottom wall of one end of the drying cylinder 2 close to the sealing cover plate 5. The bottom end of the connecting plate 25 is rotatably arranged on the fixed support plate 24. The bottom fixing frame 23 is fixed under the bottom wall of the other end of the drying cylinder 2 away from the connecting plate 25. The fixed block 21 is fixed on the bottom plate 1. One end of the pushing cylinder 22 is rotatably arranged on the fixed block 21, and the other end of the pushing cylinder 22 is rotatably arranged on the bottom fixing frame 23. The telescopic movement of the pushing cylinder 22 drives the drying cylinder 2 to rotate, and the drying cylinder 2 is rotated to an inclined position, so that one end of the sealing cover plate 5 is placed at the inclined bottom, facilitating the discharge of the flame retardant.

[0024] As Figure 3 shown, the stirring assembly 4 includes a driving motor 26, a stirring rod 28 and a stirring shaft 27. The driving motor 26 is fixed on the outer side wall of one end of the drying cylinder 2 away from the sealing cover plate 5. The stirring shaft 27 is horizontally fixed on one end of the driving motor 26. The stirring rods 28 are evenly arranged on the outer side wall of the stirring shaft 27. The driving motor 26 drives the stirring shaft 27 and the stirring rods 28 to rotate, uniformly heating the flame retardant.

[0025] During specific use, the telescopic movement of the pushing cylinder 22 drives the drying cylinder 2 to rotate, and the drying cylinder 2 is rotated to an inclined position, so that one end of the sealing cover plate 5 is placed above and one end of the driving motor 26 is placed below. The flame retardant is added into the drying cylinder 2. The electric push rod 15 extends, driving the limiting cross plate 9 to slide on the limiting sliding groove 8. The movement of the limiting cross plate 9 drives the top frame 30 to move. The movement of the top frame 30 drives the first connecting rod 19, the second connecting rod 20, the first external block 17, the second external block 18 and the connecting shaft 16 to move downward together. The connecting shaft 16 drives the roller 14 to move. When the roller 14 moves into the limiting sliding groove 8, the first connecting rod 19 and the second connecting rod 20 rotate, thereby driving the sealing cover plate 5 to move towards the drying cylinder 2, sealing the sealing cover plate 5 at one end of the drying cylinder 2. The telescopic movement of the pushing cylinder 22 drives the drying cylinder 2 to rotate, and the drying cylinder 2 is rotated to a horizontal position. The heating plate 3 is pre-started to heat the inside of the drying cylinder 2 to dry the flame retardant. The driving motor 26 drives the stirring shaft 27 and the stirring rods 28 to rotate, mixing the flame retardant evenly, so that the flame retardant is evenly heated;

[0026] After the drying is completed, the telescopic movement of the push cylinder 22 drives the drying cylinder 2 to rotate, and the drying cylinder 2 is rotated to an inclined position, so that one end of the sealing cover plate 5 is placed at the inclined bottom. The electric push rod 15 retracts, driving the limit cross plate 9 to slide on the limit chute 8. The movement of the limit cross plate 9 drives the top frame 30 to move. Since the position heights of the limit cross plate 9 and the top frame 30 are fixed, according to the parallelogram principle, the movement of the top frame 30 drives the first connecting rod 19 and the second connecting rod 20 to rotate. The rotation of the first connecting rod 19 and the second connecting rod 20 causes the first external connection block 17, the second external connection block 18, and the connecting shaft 16 to move outwards, thereby driving the sealing cover plate 5 out of the drying cylinder 2. After the connecting shaft 16 drives the roller 14 out of the limit groove 13, it moves upwards along the fixed side plate 7, moves upwards after the sealing cover plate 5 is moved out, opens one end of the drying cylinder 2, and discharges the dried flame retardant.

[0027] The above describes the present utility model and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
