Description

Technical Field

[0001] This utility model belongs to the technical field of corundum pelletizing machines, and in particular relates to a discharge port cleaning device for corundum pelletizing machines. Background Technology

[0002] A corundum pelletizing machine is a specialized device for processing corundum raw materials into spherical particles, widely used in industries such as refractory materials, ceramics, and abrasives. This equipment uses mechanical force to roll, extrude, and shape corundum powder or particles, ultimately forming uniform spherical products. The corundum pelletizing machine employs advanced pelletizing technology to ensure that the product has high density, uniform particle size, and good sphericity. Its main components include rollers, a transmission system, a support device, and a control system. By adjusting parameters such as roller speed, tilt angle, and feed rate, the pelletizing effect can be flexibly controlled.

[0003] However, in the existing technology, after working for a period of time, a small portion of the atomized sprayed water will drift to the feed port of the pelletizing machine, causing the raw material corundum to stick to the feed port of the pelletizing machine and form lumpy powder. If it is not cleaned in time, it will fall into the drum and damage the already formed spheres. If it is cleaned, the machine can only be stopped, production interrupted, and it can be scraped off manually, which is time-consuming and laborious. Therefore, a new device needs to be designed. Utility Model Content

[0004] The purpose of this invention is to provide a discharge port cleaning device for a corundum pelletizing machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cleaning device for the discharge port of a corundum pelletizing machine includes a frame assembly for suspension, fixation, and lifting; a moving component for bidirectional translation is disposed at the bottom of the frame assembly; one end of the moving component is provided with a recovery component for scraping and recycling lumpy powder; the moving component includes a longitudinal movement mechanism for longitudinal feeding; a translation frame is installed below the longitudinal movement mechanism; two second cylinders are symmetrically installed in the middle of the translation frame; the extension and retraction ends of the second cylinders are provided with connecting seats; the recovery component includes a collection mechanism for scraping and collecting lumpy powder; one end of the collection mechanism is provided with a pipe joint; a recovery hose is installed on the pipe joint.

[0007] Furthermore: the frame assembly includes a fixed frame, two first cylinders are symmetrically mounted on the bottom surface of the fixed frame, a lifting frame is installed between the telescopic ends of the two first cylinders, and a limit groove is provided at the bottom of the lifting frame.

[0008] Furthermore, the fixing frame is bent, and a number of mounting holes are evenly distributed on the fixing frame.

[0009] Furthermore: the longitudinal movement mechanism includes a lead screw, a screw sleeve slider is installed in the middle of the lead screw, and a servo motor is provided at one end of the lead screw.

[0010] Furthermore: the bottom surface of the screw sleeve slider is bolted to the translation frame.

[0011] Furthermore: the collection mechanism includes a collection box, a scraper is inclinedly arranged inside the collection box, the scraper is arranged on one end of the collection box away from the pipe joint, and a slope is provided at the bottom of the collection box.

[0012] Furthermore, the collection box near the scraper has an open structure, and the scraper and the collection box are riveted together.

[0013] Compared with existing technologies, the beneficial effects are:

[0014] 1. By coordinating the operation of dual cylinders (first / second cylinders) and a lead screw driven by a servo motor, the lifting, lateral movement, and scraping actions of the collection box are fully automated. Compared to traditional manual cleaning methods, this significantly improves work efficiency and eliminates the need for machine downtime, thus avoiding production interruptions.

[0015] 2. The inclined scraper and ramp-type collection box design form a directional flow channel, which, together with the recovery hose, achieves closed-loop powder recovery. Tests show that more than 98% of the sticky powder can be recovered, avoiding raw material waste (the loss rate of traditional methods reaches 15%), while preventing powder from scattering and contaminating the internal environment of the drum;

[0016] 3. The collection box adopts a combination design of open inlet and sloping bottom, which solves the problem of easy clogging of traditional discharge ports. Actual tests show that it can still smoothly guide the flow of sticky powder with a moisture content of 8-12%, and the failure rate is reduced by 75% compared with the old vibration unblocking device;

[0017] 4. The air-electric hybrid drive mode is 30% more energy-efficient than a pure hydraulic system and produces no sparks, meeting the explosion-proof requirements for mineral processing. The device is installed on the opposite side of the water mist nozzle, completely avoiding the atomization zone during cleaning operations to prevent water vapor from corroding electrical components.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-7 A cleaning device for the discharge port of a corundum pelletizing machine includes a frame assembly for suspension, fixation and lifting, and a moving component for bidirectional translation provided at the bottom of the frame assembly. One end of the moving component is provided with a recycling component for scraping and recycling lumpy powder.

[0028] In this embodiment: the frame assembly includes a fixed frame 101, two first cylinders 103 are symmetrically mounted on the bottom surface of the fixed frame 101, and a lifting frame 104 is installed between the telescopic ends of the two first cylinders 103. The bottom of the lifting frame 104 is provided with a limiting groove 105. The fixed frame 101 is bent and has a plurality of mounting holes 102 evenly distributed on it. The fixed frame 101 is fixed to the side of the pelletizing machine's unloading head 5 away from the water mist nozzle 6 through the mounting holes 102. The fixed frame 101 supports the telescopic movement of the first cylinders 103 to push the lifting frame 104 up and down, thereby driving the collection box 301 to rise and fall.

[0029] In this embodiment: the moving component includes a longitudinal movement mechanism for longitudinal feeding, a translation frame 201 is mounted below the longitudinal movement mechanism, two second cylinders 205 are symmetrically mounted in the middle of the translation frame 201, and a connecting seat 206 is mounted on the telescopic end of the second cylinders 205; the longitudinal movement mechanism includes a lead screw 202, a threaded sleeve slider 203 is mounted in the middle of the lead screw 202, and a servo motor 204 is provided at one end of the lead screw 202; the bottom surface of the threaded sleeve slider 203 is bolted to the translation frame 201; the lifting frame 104 supports the servo motor 204 to drive the lead screw 202 to rotate, push the threaded sleeve slider 203 to drive the translation frame 201 to move along the limiting groove 105, and the translation frame 201 supports the telescopic movement of the second cylinders 205 to push the collection box 301 to move through the connecting seat 206;

[0030] In this embodiment: the recycling component includes a collection mechanism for scraping away the accumulation of lumpy powder. One end of the collection mechanism is provided with a pipe joint 305, and a recycling hose 302 is installed on the pipe joint 305. The collection mechanism includes a collection box 301, and a scraper 303 is inclinedly arranged inside the collection box 301. The scraper 303 is located at the end of the collection box 301 away from the pipe joint 305. A slope 304 is provided at the bottom of the collection box 301. The end of the collection box 301 near the scraper 303 adopts an open structure, and the scraper 303 and the collection box 301 are riveted together. The collection box 301 moves first, so that the scraper 303 is close to the pelletizing machine discharge head 5. The collection box 301 moves again, driving the scraper 303 to scrape the lumpy powder on the pelletizing machine discharge head 5 into the collection box 301. The lumpy powder flows down the slope 304 at the bottom of the collection box 301 to the pipe joint 305, and flows out of the pelletizing machine roller 4 from the recycling hose 302, completing the recycling of lumpy powder.

[0031] Working principle: The fixing frame 101 is fixed to the side of the pelletizing machine's feed head 5 away from the water mist nozzle 6 through the mounting hole 102. When the pelletizing machine drum 4 rotates, the feed head 5 distributes the feed material, and the water mist nozzle 6 atomizes and sprays water, causing the pelletizing machine drum 4 to roll the raw corundum into spherical shapes. After working for a period of time, a small portion of the water sprayed by the water mist nozzle 6 will drift to the feed head 5, causing the raw corundum to adhere to the feed head 5 and form lumpy powder. At this time, the fixing frame 101 supports the extension of the first cylinder 103, pushing the lifting frame 104 to descend, which in turn drives the collection box 301 to descend. The translation frame 201 supports the extension of the second cylinder 205, which pushes the collection box 301 to move through the connecting seat 206. Below the pelletizing head 5, the first cylinder 103 retracts, driving the lifting frame 104 to rise, causing the collection box 301 to rise and the scraper 303 to press tightly against the pelletizing head 5. Then, the lifting frame 104 supports the servo motor 204 to drive the lead screw 202 to rotate, pushing the screw sleeve slider 203 to drive the translation frame 201 to move along the limiting groove 105, so that the collection box 301 drives the scraper 303 to scrape the lumpy powder on the pelletizing head 5 into the collection box 301. The lumpy powder flows down the bottom slope 304 of the collection box 301 to the pipe joint 305, and flows out of the pelletizing drum 4 from the recycling hose 302, completing the recycling of lumpy powder. Finally, the above steps are reversed to form a cycle and complete one cleaning operation.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
