Description

Technical Field

[0001] This utility model relates to the field of transportation device technology, and in particular to a microwave drying and transportation device for producing pellets using phosphate rock powder. Background Technology

[0002] Existing drying equipment has high heat consumption during the sintering process, requiring a certain amount of coke powder; the amount of returned material is as high as 30%; and the wear and tear on the equipment during sintering, storage and transportation is significant, resulting in a large amount of waste. Therefore, we propose a microwave drying device for producing pellets using phosphate rock powder to solve the above-mentioned problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as high heat consumption during the sintering process, the need to consume a certain amount of coke powder, a return material rate as high as 30%, and significant wear and tear on the equipment during sintering, storage, and transportation, resulting in substantial waste. This invention proposes a microwave drying device for producing pellets using phosphate rock powder.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A microwave drying and conveying device for producing pellets using phosphate rock powder includes two symmetrically arranged fixed plates, with the same strip grid fixedly connected between the two fixed plates, and the same set of conveying components for conveying materials arranged between the two fixed plates.

[0006] The bottom of the fixed plate has two symmetrically arranged rectangular holes, and the same rectangular box is slidably connected between the two rectangular holes. A sliding plate is slidably connected to the inner wall of the rectangular box. Two symmetrically arranged springs are fixedly connected between the bottom of the sliding plate and the bottom inner wall of the rectangular box. A second collection box is placed on the top of the sliding plate. An outlet is opened at one end of the rectangular box, and the outlet is used in conjunction with the second collection box. A blocking block is fixedly connected to one side inner wall of the rectangular box, and the blocking block abuts against one side of the second collection box. A pushing component for pushing the second collection box is provided inside the rectangular box.

[0007] In one possible design, the conveying assembly includes two rotating rollers rotatably connected between two fixed plates, the outer walls of the two rotating rollers being fitted with the same conveyor belt, and a servo motor being fixedly connected to one side of one of the fixed plates, the output shaft of the servo motor rotatably passing through the fixed plate and being fixedly connected to one end of one of the rotating rollers.

[0008] In one possible design, both the conveyor belt and the bar grid are inclined, with the inclination directions of the conveyor belt and the bar grid being opposite, and the conveyor belt being located directly below the bar grid.

[0009] In one possible design, the pushing assembly includes a pad fixedly connected to the inner wall of the bottom of a rectangular box, a first collection box slidably connected to the top of the pad, and two symmetrically arranged compression springs fixedly connected between one side of the first collection box and one side of the inner wall of the rectangular box.

[0010] In one possible design, a fixing block is fixedly connected to one side of the rectangular box, and the same baffle is slidably connected between the two fixing plates. A notch is provided at one bottom corner of the baffle, and the notch is used in conjunction with the baffle.

[0011] In one possible design, a support plate is fixedly connected to one side of the rectangular box, a resilient switch is provided on the top of the support plate, and a buzzer alarm is provided on one side of the fixed plate, with the buzzer alarm electrically connected to the resilient switch.

[0012] In this application, during use, 60% of the sieved sample, 32% of the dust sample, and 8% of the binder are added to a mixer, along with 15% water for mixing. Pelletizing and drying: The material from the mixer is conveyed by belt to a pelletizing machine. After passing through this device, it is transported to a dryer equipped with microwave technology for drying at 150℃. The undersized material is returned to the pelletizing machine for pelletizing. Sieving and filtering: After drying, the crushed material is screened off by a straight bar screen and conveyed by belt to the mixer for repeated pelletizing and drying operations. Product entering the electric furnace: The pellets that meet the requirements after pelletizing and drying are added to the electric furnace for the production process.

[0013] The material falls onto the bar grid and slides down the inclined surface of the bar grid. At this time, the formed material continues to slide into the drying box, while the unformed material falls through the bar grid to the top of the conveyor belt. The servo motor is started, and the output shaft of the servo motor drives the rotating roller to rotate. The rotating roller drives the conveyor belt to move forward. At this time, the material slides down the inclined surface of the conveyor belt into the interior of the second collection box for collection. At the same time, the baffle can prevent the material from being discharged.

[0014] As the material gradually falls, the second collection box moves vertically downwards along with the sliding plate under gravity. The sliding plate compresses the spring. When the sliding plate no longer touches one side of the first collection box, and the second collection box no longer touches the block, the first collection box moves vertically downwards under the elastic force of the compression spring. The first collection box pushes the second collection box to move laterally, and the second collection box is discharged from the inside of the outlet, landing on the support plate and pressing the elastic switch, which can trigger the buzzer alarm to remind the staff. The first collection box is now receiving material to prevent it from falling to the ground. The staff can then remove the second collection box. To put it back, the baffle can be moved vertically upwards. At this point, the notch no longer blocks the fixing block, allowing the rectangular box to be moved, thus resetting the first and second collection boxes. It is convenient to use.

[0015] In this utility model, the microwave drying and conveying device for producing pellets using phosphate rock powder can achieve the effect of conveying materials through the conveying components.

[0016] In this utility model, the microwave drying and conveying device for producing pellets using phosphate rock powder can achieve the effect of pushing the second collection box through the pushing component;

[0017] In this invention, the material slides down the inclined surface of the strip grid. Unformed material falls through the strip grid to the top of the conveyor belt. The baffle prevents material from being discharged. As the material gradually falls, the second collection box moves vertically downward under the action of gravity, and the first collection box moves vertically downward under the action of the spring. The second collection box is discharged from the inside of the outlet, falls onto the support plate, and squeezes the elastic switch, which can trigger the buzzer alarm to remind the staff.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Reference Figure 1-5 A drying and conveying device includes: two symmetrically arranged fixed plates 1, with a single strip grid 8 fixedly connected between the two fixed plates 1; 60% of a sieve sample, 32% of a dust sample, and 8% of an adhesive are added to a mixer with 15% water for mixing; pelletizing and drying: the material from the mixer is conveyed by belt to a pelletizing machine; after passing through this device, it is transported to a dryer equipped with microwave technology for drying at 150°C; undersized material is returned to the pelletizing machine for pelletizing; screening and filtration: after drying, the crushed material is screened off by a straight bar screen and conveyed by belt to the mixer for repeated pelletizing and drying operations; product entering the electric furnace: the qualified pellets after pelletizing and drying enter the electric furnace for the production process; a set of conveying components for conveying materials is provided between the two fixed plates 1, the conveying components including two rotating rollers 11 rotatably connected between the two fixed plates 1; the two rotating rollers 11... The outer wall of roller 11 is fitted with the same conveyor belt 9. A servo motor 10 is fixedly connected to one side of a fixed plate 1. The output shaft of the servo motor 10 rotates through the fixed plate 1 and is fixedly connected to one end of one of the rotating rollers 11. The conveyor belt 9 and the strip grid 8 are both inclined. The inclination directions of the conveyor belt 9 and the strip grid 8 are opposite. The conveyor belt 9 is located directly below the strip grid 8. The material falls onto the strip grid 8 and slides down along the inclined surface of the strip grid 8. At this time, the formed material continues to slide into the drying box, and the unformed material falls through the strip grid 8 to the top of the conveyor belt 9. The servo motor 10 is started. The output shaft of the servo motor 10 drives the rotating roller 11 to rotate. The rotating roller 11 drives the conveyor belt 9 to move forward. At this time, the material slides down along the inclined surface of the conveyor belt 9 into the interior of the second collection box 15 for collection. At the same time, the baffle 5 can prevent the material from being discharged.

[0027] Two rectangular holes 12 are symmetrically arranged at the bottom of the fixed plate 1. A rectangular box 7 is slidably connected between the two rectangular holes 12. A sliding plate 21 is slidably connected to the inner wall of the rectangular box 7. Two springs 20 are symmetrically arranged and fixedly connected between the bottom of the sliding plate 21 and the bottom inner wall of the rectangular box 7. A second collection box 15 is placed on the top of the sliding plate 21. An outlet 17 is opened at one end of the rectangular box 7 and is used in conjunction with the second collection box 15. A blocking block 16 is fixedly connected to the inner wall of one side of the rectangular box 7 and abuts against one side of the second collection box 15. A pushing assembly for pushing the second collection box 15 is provided inside the rectangular box 7. The pushing assembly includes a pad 18 fixedly connected to the bottom inner wall of the rectangular box 7. A first collection box 14 is slidably connected to the top of the pad 18. Two compression springs 19 are symmetrically arranged and fixedly connected between one side of the first collection box 14 and one side inner wall of the rectangular box 7. A fixing block 6 is fixedly connected to one side of the rectangular box 7. A sliding connection is made between the two fixed plates 1. The same baffle 5 has a notch 13 at one corner of its bottom. The notch 13 works in conjunction with the baffle 5 to allow the material to fall gradually. Under the action of gravity, the second collection box 15 drives the sliding plate 21 to move vertically downward. The sliding plate 21 compresses the spring 20. When the sliding plate 21 no longer touches one side of the first collection box 14, and the second collection box 15 no longer touches the block 16, the first collection box 14 moves vertically downward under the elastic force of the compression spring 19. The first collection box 14 pushes the second collection box 15 to move horizontally. The second collection box 15 is discharged from the inside of the outlet 17, falls onto the support plate 4, and compresses the elastic switch 3, which can trigger the buzzer alarm 2 to remind the staff that the first collection box 14 is receiving material to prevent the material from falling to the ground. The staff can remove the second collection box 15. When putting it back, the baffle 5 can be moved vertically upward. At this time, the notch 13 no longer jams the fixing block 6, and the rectangular box 7 can be moved, thereby resetting the first collection box 14 and the second collection box 15. It is convenient to use.
