Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ferric phosphate processing technology, specifically relating to an anti-clogging cooling kiln for ferric phosphate processing. Background Technology
[0002] In the industrial production of ferric phosphate, the calcined material needs to be cooled to below 100°C before further processing. Anti-clogging cooling kilns, combining cooling and anti-clogging functions, have become the mainstream equipment in the industry. Most existing anti-clogging cooling kilns are rotary, with lifting plates fixed to the kiln wall rotating with the kiln body. These plates lift and scatter the material, forming a "material curtain" to increase the contact area with the cooling medium and enhance heat exchange. However, in actual operation, after the lifting plates carry the material to the upper part of the kiln, the falling material easily impacts the bottom lifting plates. Furthermore, the material has high hardness and is prone to agglomeration, resulting in high impact energy that may exceed the bearing capacity of the lifting plates. Long-term impact can lead to damage to the fixed structure of the lifting plates, deformation, tilting, or even detachment of the plates.
[0003] Tilting the lifting plates can trigger a chain of problems: First, it prevents the formation of an effective "material curtain," reducing the heat exchange area by 40%-60% and drastically decreasing cooling efficiency, requiring supplemental cooling. Second, uneven material distribution and accumulation lead to insufficient internal cooling, affecting product quality and exacerbating kiln wall wear. Third, disordered material conveying can easily clog the discharge outlet, interrupting production. The current solution is to shut down the machine and replace the lifting plates. However, the kiln's internal space is narrow, requiring maintenance personnel to enter the kiln to disassemble the old lifting plates and then reposition and install the new ones. To avoid burns to maintenance personnel, a significant amount of time must be spent waiting for the kiln to cool down, making the entire maintenance process time-consuming and impacting the efficiency of ferric phosphate processing.

[0007] Furthermore, the height of the left support frame is higher than the height of the right support frame.
[0008] Furthermore, the left and right sides of the cooling kiln body are slidably connected to the adjacent side of the two limiting rings inside the left and right limiting frames, the outer side of the left end of the cooling kiln body is slidably connected to the inner side of the left limiting frame, and the outer side of the right end of the cooling kiln body is slidably connected to the inner side of the right limiting frame.
[0009] Furthermore, the interior of the cooling kiln is provided with rectangular grooves at equal intervals, and a through groove is provided inside the cooling kiln near the center of the rectangular grooves.

[0013] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, through the installation and removal mechanism, allows for the removal of a damaged lifting plate from the cooling kiln body when it is damaged. By rotating the bolts in the sliding plate connected to the damaged lifting plate at the outer end of the cooling kiln body, the plate can be disassembled from its threaded hole. This removes the sliding plate from its fixed rectangular slot. Then, by moving the left or right limiting frame U away from the cooling kiln body, the sliding plate with the damaged lifting plate welded to it can be pulled out from inside the cooling kiln body. The plate can then be repaired or replaced from the outer end of the cooling kiln body, eliminating the need for maintenance personnel to enter the cooling kiln body. This reduces the time required for maintenance and improves the efficiency of ferric phosphate processing.
[0014] This invention incorporates a cooling mechanism. When cooling ferric phosphate in this kiln, the motor is started to rotate the kiln body, and ferric phosphate is poured into the kiln body through the feed pipe. At the same time, the rotating lifting plates inside the kiln body scoop up the ferric phosphate and allow it to fall from a height. Simultaneously, ambient temperature gas is introduced into the kiln body through the air inlet pipe. As the gas passes over the falling ferric phosphate, it cools the high temperature. As the ferric phosphate moves to the right along the inside of the kiln body, which slopes downwards to the right, it is continuously scooped up and cooled, ensuring that the ferric phosphate is eventually cooled to a sufficiently low temperature before falling from the hopper and being collected.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0019] This specific embodiment is an anti-clogging cooling kiln for ferric phosphate processing, and its structural schematic diagram is shown below. Figures 1 to 3 As shown, the system includes a left support frame 1, with a left limiting frame 2 welded to its upper end. A right support frame 3 is located to the right of the left support frame 1, with a right limiting frame 4 welded to its upper end. A cooling kiln body 5 for cooling ferric phosphate is positioned between the left limiting frame 2 and the right limiting frame 4. The height of the left support frame 1 is higher than the height of the right support frame 3. This ensures that the cooling kiln body 5 between the left limiting frame 2 and the right support frame 3 is supported in a left-high-right-low configuration, guaranteeing that the ferric phosphate entering the cooling kiln body 5 will slide to the right.
[0020] The cooling kiln body 5 has a cooling mechanism at its outer end. This mechanism includes an air inlet pipe 601 fixedly connected to the middle position inside the right limiting frame 4, an exhaust pipe 602 fixedly connected to the middle position inside the left limiting frame 2, a feed pipe 603 fixedly connected to the upper left end inside the left limiting frame 2, a right support seat 604 located on the lower right side of the cooling kiln body 5, and a left support seat 605 located on the lower left side of the cooling kiln body 5. A support plate 606 is welded to the upper right side of the right support seat 604 and the left support seat 605. The support plate 606 has an internal... A rotating shaft 607 is rotatably connected at the middle position. A rotating roller 608 is fixedly connected at the middle position of the outer side of the rotating shaft 607. A reducer 609 is installed at the middle position of the upper side of the right support 604. A motor 610 is installed at the upper left end of the right support 604. A drive gear 611 is fixedly connected to the outer side of the output shaft of the reducer 609. An outer fixing ring 612 is fixedly connected to the outer side of the cooling kiln body 5. The outer circumferential surface of the rotating roller 608 is in rolling contact with the outer side of the outer fixing ring 612. The outer side of the outer fixing ring 612 is provided with anti-slip texture. Thus, when the outer fixing ring 612 contacts the rotating roller 608, there is sufficient wear between the rotating roller 608 and the outer fixing ring 612, thereby ensuring smooth relative rotation between the rotating roller 608 and the outer fixing ring 612.
[0021] In addition, an external gear ring 613 is fixedly connected to the right side of the outer side of the cooling kiln body 5, and a limiting ring 614 is fixedly connected to the inner side of the left limiting frame 2 and the right limiting frame 4. The left and right sides of the cooling kiln body 5 are slidably connected to the adjacent side of the two limiting rings 614 inside the left limiting frame 2 and the right limiting frame 4. The outer side of the left end of the cooling kiln body 5 is slidably connected to the inner side of the left limiting frame 2, and the outer side of the right end of the cooling kiln body 5 is slidably connected to the inner side of the right limiting frame 4. A feeding hopper 615 is fixedly connected to the lower end of the right limiting frame 4. The input shaft end of the reducer 609 is connected to the output shaft end of the motor 610, and the drive gear 611 meshes with the external gear ring 613. Thus, when the output shaft of the starting motor 610 rotates and is driven by the reducer 609, it can drive the drive gear 611 to rotate, which in turn drives the external gear ring 613 to rotate, causing the cooling kiln body 5 to rotate inside the left limit frame 2 and the right limit frame 4. This allows the iron phosphate inside to slide to the right along its inner side. The rotating lifting plate 702 inside the cooling kiln body 5 will continuously lift and drop the cooling kiln body 5, making the iron phosphate more fully contacted with the cooling gas, while preventing the iron phosphate from clogging in the cooling kiln body 5 and preventing it from moving smoothly to the right.
[0022] Cooperate Figure 4As shown, the cooling kiln body 5 is equipped with a disassembly and assembly mechanism, which includes a sliding plate 701 installed inside the cooling kiln body 5. Rectangular slots are evenly spaced inside the cooling kiln body 5. A through slot is formed near the center of the rectangular slots inside the cooling kiln body 5. The outer side of the sliding plate 701 is slidably connected to the inner side of the rectangular slots. The outer side of the lifting plate 702 near the sliding plate 701 is slidably connected to the inner side of the through slot. Lifting plates 702 are welded at equal intervals on the side of the sliding plate 701 facing the center of the cooling kiln body 5. Bolts 703 are installed at both the front and rear ends of the cooling kiln body 5. Threaded holes are symmetrically formed on the left and right sides of the rectangular slots away from the center of the cooling kiln body 5. Insertion holes are formed on the left and right sides of the lifting plates 702 away from the lifting plate 702. The outer side of the bolt 703 is threadedly connected to the inner side of the threaded hole, and the outer side of the bolt 703 away from its thread head is slidably connected to the inner side of the insertion hole. Therefore, when the lifting plate 702 inside the cooling kiln 5 is damaged, the bolt 703 in the sliding plate 701 connected to the damaged lifting plate 702 at the outer end of the cooling kiln 5 can be rotated to remove it from the threaded hole, so that the sliding plate 701 is no longer fixed in the rectangular groove. Then, the left limit frame 2 or the right limit frame 4U can be moved away from the cooling kiln 5, and the sliding plate 701 with the damaged lifting plate 702 welded on can be pulled out from inside the cooling kiln 5. Then, the lifting plate 702 can be repaired or replaced at the outer end of the cooling kiln 5, so that maintenance personnel do not need to enter the cooling kiln 5 to repair or replace the lifting plate 702. This eliminates the need to wait for the cooling kiln 5 to cool down, reduces the time required for the maintenance of the cooling kiln 5, and improves the efficiency of ferric phosphate processing.
[0023] Working principle: When cooling ferric phosphate, the motor 610 is started first. Its output shaft rotates and is driven by the reducer 609, which drives the drive gear 611 to rotate. This drives the external gear ring 613 to rotate, causing the cooling kiln body 5 to rotate inside the left limit frame 2 and the right limit frame 4. Then, the ferric phosphate to be cooled is poured into the cooling kiln body 5 through the feed pipe 603. At the same time, room temperature gas is introduced into the cooling kiln body 5 through the air inlet pipe 601. The lifting plate 702 inside the rotating cooling kiln body 5 scoops up the ferric phosphate while rotating, and then makes it fall from a height. The air entering the cooling kiln body 5 passes over the surface of the falling ferric phosphate, absorbs the heat inside the ferric phosphate, and is then discharged from the exhaust pipe 602 at the left end. The continuously lifted ferric phosphate is continuously cooled. Finally, the cooled ferric phosphate is discharged from the discharge hopper 615 at the right end and collected.
[0024] All technical features in this embodiment can be freely combined according to actual needs.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
