Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to an automatic feeding device for insoluble phase reactor residue. Background Technology

[0002] Insoluble phase residues refer to substances that remain insoluble in the solvent or reaction system during chemical reactions or distillations. These substances include solid particles, high-boiling-point compounds, polymers, or other difficult-to-dissolve components. The treatment of insoluble phase residues is a crucial step in industrial production, and its harmless disposal and resource utilization should be achieved.

[0003] When utilizing resources, the insoluble phase residue needs to be fed into the pyrolysis vessel through an automatic feeding device, namely a screw feeder. However, due to the high viscosity of the insoluble phase residue, it is easy to stick to the screw blades of the screw feeder, which is not easy to clean. After long-term use, the adhesive layer becomes thicker and thicker, which is not conducive to feeding. Utility Model Content

[0004] The purpose of this invention is to provide an automatic feeding device for insoluble phase residues that is reasonably structured and reliable in use, solving the problem that insoluble phase residues adhering to the spiral blades of the spiral feeder are not easy to clean, ensuring smooth feeding and production efficiency.

[0005] The technical solution of this utility model is:

[0006] An automatic feeding device for insoluble phase reactor residue includes a screw propeller body. The key technical features are: an arc-shaped positioning plate is slidably connected to the upper surface of the outer wall of the screw propeller body; multiple nozzles are spaced along the length of the screw propeller body on the arc-shaped positioning plate, with the nozzles facing the screw blades of the screw propeller; clearance openings corresponding to each nozzle are provided on the outer wall of the screw propeller body; the upper inlet of each nozzle is connected to a water supply pipe; both ends of the water supply pipe are provided with sealing plates connected to the arc-shaped positioning plate; a water inlet connector is connected to the middle of the water supply pipe; an arc-shaped gear ring structure is fixed to the axial upper surface of the arc-shaped positioning plate; a protective cover is provided on the upper part of the screw propeller body; a motor reducer is provided on the side wall of the protective cover; and a transmission gear meshing with the arc-shaped gear ring structure is provided on the output shaft of the motor reducer.

[0007] The aforementioned automatic feeding device for insoluble phase reactor residue has an arc-shaped clearance hole on the protective cover corresponding to the water inlet connector, and the outer end of the water inlet connector is connected to a retractable water supply pipeline.

[0008] The aforementioned automatic feeding device for insoluble phase reactor residue has arc-shaped tracks at both ends of the arc-shaped positioning plate, and an arc-shaped groove on the outer wall of the screw propeller body that cooperates with the arc-shaped tracks.

[0009] In the aforementioned automatic feeding device for insoluble phase residue, the centerline of the nozzle forms an acute angle greater than 45 degrees with the horizontal plane.

[0010] The aforementioned automatic feeding device for insoluble phase residue has a water outlet at the lower end of the protective cover to transfer water leaking from the nozzle out of the protective cover.

[0011] The aforementioned automatic feeding device for insoluble phase reactor residue has a cleaning water discharge branch on the side wall of the discharge port of the screw propeller body.

[0012] The beneficial effects of this utility model are:

[0013] After feeding, the motor reducer, transmission gears, and arc-shaped gear ring structure drive the arc-shaped positioning plate to rotate around the axis of the screw propeller body at a certain angle. This aligns the nozzles with the clearance openings on the outer wall of the screw propeller body. The cleaning fluid is sprayed out through each nozzle and onto the screw blades. The screw blades of the screw propeller body are cleaned by the cleaning fluid during rotation. Finally, the cleaning fluid is discharged through the cleaning water discharge branch.

[0018] The present invention will be described in detail with reference to the accompanying drawings.

[0019] like Figures 1-3 As shown, the automatic feeding device for the insoluble phase reactor residue includes a screw propeller body 13.

[0020] In this embodiment, an arc-shaped positioning plate 4 is slidably connected to the upper surface of the outer wall of the propeller body 13. At both ends of the arc-shaped positioning plate 4 are arc-shaped tracks 17, and the outer wall of the propeller body 13 is provided with arc-shaped grooves that cooperate with the arc-shaped tracks 17.

[0021] The arc-shaped positioning plate 4 is provided with a plurality of nozzles 5 at intervals along the length of the spiral propeller body 13. The nozzles 5 face the spiral blades 9 of the spiral propeller 13. The outer wall of the spiral propeller body 13 is provided with clearance openings 14 corresponding to the nozzles 5. In this embodiment, the center line of the nozzle 5 forms an acute angle greater than 45 degrees with the horizontal plane.

[0022] Each nozzle 5 has its upper inlet connected to a water supply pipe 3. Both ends of the water supply pipe 3 are equipped with sealing plates 18 that are connected to the arc-shaped positioning plates 4. A water inlet connector 7 is connected to the middle of the water supply pipe 3. A retractable water supply pipe 6 is connected to the outer end of the water inlet connector 7.

[0023] An arc-shaped gear ring structure 16 is fixed on the upper surface of the axial end of the arc-shaped positioning plate 4. A protective cover 2 is provided on the upper part of the spiral propeller body 13. A motor reducer 10 is provided on the side wall of the protective cover 2. A transmission gear 15 that meshes with the arc-shaped gear ring structure 16 is provided on the output shaft of the motor reducer 10.

[0024] In this embodiment, the protective cover 2 is provided with an arc-shaped clearance hole 8 corresponding to the water inlet connector 7, and the lower end of the protective cover 2 is provided with a water outlet hole 19 to transfer water leaking from the nozzle out of the protective cover. The unloading port 11 of the screw propeller body 13 is provided with a cleaning water discharge branch 12 on its side wall.

[0025] Working principle:

[0026] 1. During normal feeding, the insoluble phase residue enters through the feed port 1 of the screw propeller body 13, and is then propelled by the screw blades 9 to the discharge port 11 side, finally falling into the pyrolysis reactor. During this process, the arc-shaped positioning plate 4 blocks the clearance port 14 on the outer wall of the screw propeller body 13 to prevent material from moving outward.

[0027] 2. After feeding is completed, start the motor reducer 10, and use the cooperation of the transmission gear 15 and the arc-shaped gear ring structure 16 to drive the arc-shaped positioning plate 4 to rotate around the axis of the spiral propeller body 13 by a certain angle, so that each nozzle 5 corresponds to the clearance port 14 on the outer wall of the spiral propeller body 13.

[0028] 3. Cleaning fluid is injected into the water supply pipe 3 through the retractable water supply pipe 6 and the water inlet connector 7. The cleaning fluid is sprayed out through each nozzle 5 and sprayed onto the spiral blades 9. The spiral blades 9 of the spiral propeller body 13 are washed clean by the cleaning fluid during rotation. Finally, the cleaning fluid is discharged through the cleaning water discharge branch 12. It should be noted that the pressure of the liquid sprayed from the nozzles 5 can wash away any material that may be stuck at the avoidance port 14.

[0029] 4. After cleaning, the motor reducer 10 reverses, and the arc-shaped positioning plate 4 is reset by the cooperation of the transmission gear 15 and the arc-shaped gear ring structure 16, waiting for the next feeding operation.

[0030] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this utility model.
