[0031] The present application will be described in detail below with reference to the drawings and in combination with the embodiments. Embodiment 1

[0032] Referring to Figures 1-9 In the embodiment of the present application, a furfuryl alcohol production waste residue drying device comprises a drying seat 1, a drying box 5 is installed on the drying seat 1, an upper disturbance plate 17 is hingedly installed on the upper end of the side wall of the drying box 5, a lower disturbance plate 18 is hingedly installed on the lower end of the side wall of the drying box 5, a cavity tube 15 is in through communication between the region between the upper disturbance plate 17 and the lower disturbance plate 18 corresponding to the position of the side wall of the drying box 5, so that the waste residue dried by the upper disturbance plate 17 can be introduced onto the lower disturbance plate 18 through the cavity tube 15, an extension mechanism for changing the relative position between the upper disturbance plate 17 and the lower disturbance plate 18 is arranged on the drying box 5, and a gas injection mechanism for injecting hot gas onto the upper disturbance plate 17 and the lower disturbance plate 18 is further arranged in the drying box 5, and a driving mechanism for driving the extension mechanism and the gas injection mechanism to operate is further installed on the outer wall of the drying box 5.

[0033] First, the driving motor 3 is started to make the extension mechanism and the gas injection mechanism work, the extension mechanism makes the waste residue on the upper disturbance plate 17 and the lower disturbance plate 18 form effective movement, and in this process, the waste residue in the above movement state is completely dried in all directions by the gas injection mechanism, finally ensuring the effective recovery of the entire waste residue.

[0034] In one case of the embodiment, the extension mechanism comprises an extension shaft 22 slidingly arranged on the side wall of the drying box 5, an extension block 23 is fixedly installed on the extension shaft 22, a push-pull rod 25 is hingedly arranged at both ends of the extension block 23, an abutting column 26 is fixedly installed at the end of the push-pull rod 25 away from the extension block 23, the extension mechanism further comprises a lower abutting block 27 fixed on the lower disturbance plate 18 and an upper abutting block 29 fixed on the upper disturbance plate 17, an abutting groove 28 is arranged on the upper abutting block 29 and the lower abutting block 27 respectively, and the abutting column 26 is slidingly arranged in the abutting groove 28.

[0035] During the reciprocating movement of the extension shaft 22, on the one hand, the hinged action of the extension block 23 makes the two push-pull rods 25 drive the corresponding abutting columns 26 to slide along the inside of the abutting groove 28, and finally under the action of the upper abutting block 29 and the lower abutting block 27, the upper disturbance plate 17 and the lower disturbance plate 18 move in opposite directions, finally making the waste residue move in a shaking manner to increase its drying effect.

[0036] In addition, in the embodiment, the upper abutting blocks 29 are symmetrically arranged on the upper side of the bottom of the upper disturbance plate 17, the lower abutting blocks 27 are symmetrically arranged on the lower side of the top of the lower disturbance plate 18, and a plurality of drying holes are arranged on the upper disturbance plate 17 and the lower disturbance plate 18, respectively. By further limiting the positions of the upper abutting blocks 29 and the lower abutting blocks 27, the upper disturbance plate 17 and the lower disturbance plate 18 can be more stable during the up-down swinging, and the hot air flow can effectively pass through the upper disturbance plate 17 and the lower disturbance plate 18 to contact the furfuryl alcohol waste residue, thereby further improving the reliability of the device.

[0037] In the preferred embodiment of the present application, the air injection mechanism includes an air inlet cylinder 30 fixed on the inner wall of the drying box 5, a rotating cylinder 19 rotatably arranged in the air inlet cylinder 30, a gas guide cavity 34 arranged in the rotating cylinder 19, and a plurality of rotating leaves 20 arranged on the outer wall of the rotating cylinder 19 and in communication with the gas guide cavity 34. The rotating leaves 20 increase in diameter along the axis of the rotating cylinder 19 from the air inlet end, but the maximum diameter cannot interfere with the normal movement area of the upper disturbance plate 17 and the lower disturbance plate 18. A plurality of air injection holes 21 are arranged on the rotating leaves 20. An internal thread hole 35 is arranged in the rotating cylinder 19 in the axial direction and outside the gas guide cavity 34. The internal thread hole 35 cooperates with an external thread area 24 arranged on the end of the telescopic shaft 22, so that the linear motion of the telescopic shaft 22 can be converted into the rotation motion of the rotating cylinder 19. The air injection mechanism further includes a gas guide assembly for guiding hot gas into the gas guide cavity 34.

[0038] The gas guide assembly includes a gas guide pump 11 arranged on the upper wall of the drying box 5.

The other end of the gas guide pump 11 is communicated with an air outlet pipe 12, and the air outlet pipe 12 is communicated with the air inlet cylinder 30. A gas guide hole 33 in communication with the gas guide cavity 34 is arranged on the side wall of the rotating cylinder 19 arranged on the air inlet cylinder 30, so that the hot gas flow introduced into the air inlet cylinder 30 can be introduced into the gas guide cavity 34.

[0039] During the reciprocating motion of the telescopic shaft 22, the rotating cylinder 19 rotates clockwise and counterclockwise along its own direction through the cooperation of the external thread area 24 and the internal thread hole 35, so that the rotating leaves 20 move correspondingly. In this process, the hot gas flow is introduced into the air inlet cylinder 30 by the gas guide pump 11, and then introduced into the rotating leaves 20 through the gas guide hole 33 and the gas guide cavity 34, so that the rotating leaves 20 can spray hot gas flow through the air injection holes 21 while rotating reciprocally, thereby achieving the effective drying of the furfuryl alcohol waste residue.

[0041] The limiting assembly comprises a limiting strip 39 fixed on the side wall of the driving cylinder 2 and a limiting groove 40 arranged on the side wall of the telescopic inclined block 36, and the limiting strip 39 is slidingly arranged in the limiting groove 40.

[0042] The driving motor 3 is started, the driving inclined block 37 is driven to move synchronously under the action of the driving shaft 38, then the telescopic inclined block 36 drives the telescopic shaft 22 to move linearly along the axial direction under the cooperation of the wedge surface 41 and the limiting assembly, and the telescopic shaft 22 moves reciprocatingly linearly under the action of the telescopic spring 42, so that the normal operation of the air injection mechanism and the telescopic mechanism is ensured.

[0043] Meanwhile, the feeding port 14 is arranged on the upper end of the drying box 5, so as to ensure that the workers can introduce the waste residues into the drying box 5, and the discharge pipe 4 is arranged on the side wall of the drying box 5 corresponding to the position of the lower disturbing plate 18, so as to ensure that the dried furfuryl alcohol of large particles can be effectively discharged.

[0044] In addition, the supporting legs 6 are arranged at the four corners of the bottom of the drying seat 1, so as to effectively support the entire drying device, and the discharge hopper 16 is arranged at the center of the bottom of the drying seat 1, the discharge hopper 16 is in communication with the bottom of the drying box 5, so as to ensure that the dried furfuryl alcohol of small particles can be effectively discharged.

[0045] By arranging the discharge pipe 4 and the discharge hopper 16, the entire waste residues of furfuryl alcohol after drying can be recycled, and the waste residues after drying can be classified, so that the working application range of the drying device is further widened. Embodiment 2

[0046] In order to further facilitate the workers to introduce the waste residues in the furfuryl alcohol production into the drying box 5 and ensure the automatic introduction of the waste residues, the application further provides another embodiment, which is different from the above-mentioned embodiment in that the drying seat 1 is provided with a lifting mechanism for introducing the waste residues of furfuryl alcohol into the drying box 5.
