Description

Technical Field

[0001] The utility model relates to the field of refractory material drying equipment, and more specifically, to a refractory material drying device. Background Art

[0002] At present, all materials whose physical and chemical properties allow them to be used in high temperature environments are called refractory materials. Acidic refractory materials have silicon oxide as the main component, and commonly used ones are silica bricks and clay bricks. Neutral refractory materials have aluminum oxide, chromium oxide or carbon as the main components. Alkaline refractory materials have magnesium oxide and calcium oxide as the main components, and commonly used ones are magnesium bricks. After the refractory materials are produced and formed, they need to be fully dried to ensure their use strength and avoid performance damage or reduction caused by water or moisture in the refractory materials.

[0003] Although the closed box-type refractory material drying equipment has many advantages during use, the hot air inside it usually enters from one end of the bottom through a pipe and is discharged from the other end of the top. When multiple layers of refractory materials are stacked and dried through brackets, it is difficult for the hot air to contact each layer of refractory materials, which is not conducive to the uniformity of drying the refractory materials. Moreover, when it is necessary to inspect or take out a certain layer of refractory materials placed therein, the closed box-type refractory material drying equipment needs to be shut down and the box door needs to be opened to inspect or take out a certain layer of refractory materials, which is not conducive to the continuity of the drying process. Therefore, we propose a refractory material drying device to solve the above-mentioned problems. Utility Model Content

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention specification; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0028] Embodiment 1:

[0029] See also Figure 1-Figure 6 A refractory material drying device includes a plurality of circular drying baskets 1 with the same structure. The circular drying basket 1 includes a frame 15. A square air inlet pipe 16 is fixedly installed on one side of the frame 15. One end of the square air inlet pipe 16 penetrates into the frame 15. A plurality of arc-shaped air guide plates 17 are fixedly welded to one end of the square air inlet pipe 16 located inside the frame 15. A sinking opening 1501 is opened at the bottom of the frame 15 where one end of the square air inlet pipe 16 is connected. The bottom of the sinking opening 1501 is A square air outlet duct 18 is fixedly installed on the bottom of the inner wall of the frame 15, and a plurality of support columns 19 are fixedly welded on the bottom of the inner wall of the frame 15. A material loading plate 20 is fixedly installed inside the frame 15 through the plurality of support columns 19. A plurality of installation cavities 2001 are staggeredly opened inside the material loading plate 20, and a plurality of refractory material clamping mesh plates 21 of the same structure are arranged inside the plurality of installation cavities 2001. An observation window 1502 is also opened on one side of the outer wall of the frame 15, and a high temperature resistant glass panel is fixedly installed inside the observation window 1502;

[0030] The refractory material clamping mesh plate 21 includes an upper mesh plate 22 and a lower mesh plate 23. One side of the upper mesh plate 22 and the lower mesh plate 23 are rotatably connected by a combination page, and the other side of the upper mesh plate 22 and the lower mesh plate 23 are connected by a quick-release fastener 24. A rotating rod 25 is fixedly installed at the bottom of the lower mesh plate 23. A group of clamps 26 are sleeved on both ends of the outer wall of the rotating rod 25, and the clamps 26 are fixedly installed at the bottom of the loading plate 20. The other end of the rotating rod 25 passes through the outside of the frame 15.

[0031] The hot air flow principle inside the circular drying basket of this refractory drying device is:

[0032] First, place the refractory material (mainly the refractory material with sheet structure) on the lower mesh plate 23 of the refractory material clamping mesh plate 21, then cover the mesh plate 22 and clamp it with the quick-release fastener 24. At this time, the refractory material placement process is completed, and then the hot air enters the frame 15 through one end of the square air inlet pipe 16, and flows in a circular shape along the inner wall of the frame 15. Since a plurality of arc-shaped air guide plates 17 are fixedly welded at the end of one end of the square air inlet pipe 16, the hot air can also be guided by the arc-shaped air guide plates 17 and blown out in different arc-shaped surfaces, so as to evenly flow to the loading plate 20, so that the hot air contacts the placed refractory material more evenly, and then the hot air is discharged through the sinking opening 1501 and the square air outlet pipe 18 and flows to the connecting pipe 2;

[0033] During the drying process, the internal drying conditions can be observed through the observation window 1502. At this time, since a rotating rod 25 is fixedly installed at the bottom of the lower mesh plate 23, and one end of the rotating rod 25 passes through the outside of the frame 15, each rotating rod 25 can be rotated during the drying process to change the angle between the upper mesh plate 22 and the lower mesh plate 23 on the loading plate 20, thereby increasing the windward area of ​​the refractory material and the hot air, which is beneficial to the rapid drying of the refractory material.

[0034] Embodiment 2:

[0035] In view of the above embodiment 1, for further description, refer to Figure 1 and Figure 2 , the other end of the square air outlet pipe 18 is fixedly installed with a connecting pipe 2, the other end of the connecting pipe 2 and the other end of the square air inlet pipe 16 are fixedly installed with a corrugated hose 3, the end of the corrugated hose 3 located at the other end of the square air inlet pipe 16 is fixedly installed with a control air valve 4, the control air valves 4 on several circular drying baskets 1 are connected through an air inlet pipe 5, a heating box 6 is fixedly installed at the end of the bottom of the air inlet pipe 5, a fan 7 is fixedly installed on one side of the heating box 6, several electric heating rods with the same structure are fixedly installed inside the heating box 6, and a temperature sensor is fixedly installed at the air outlet inside the heating box 6 located at the connection between the air inlet pipe 5 and the heating box 6;

[0036] The ends of several corrugated hoses 3 located on one side of several connecting pipes 2 are connected by a countercurrent return air duct 8, and a drying box 9 is fixedly installed at one end of the bottom of the countercurrent return air duct 8. The other side of the drying box 9 is connected to the air inlet of the fan 7 through a curved pipe 10, and the interior of the drying box 9 is filled with drying cotton boards.

[0037] The principle of hot air flow and removal into the circular drying basket of this refractory drying device is as follows:

[0038] First, the fan 7 is started to blow air into the heating box 6, and the electric heating rod is heated inside the heating box 6 to form hot air with a certain amount of heat. At this time, the hot air passes through the air inlet pipe 5 and the corresponding control air valve 4 into the corresponding corrugated hose 3, and then passes through the corrugated hose 3 into the corresponding square air inlet pipe 16, so that it can smoothly enter the circular drying basket 1;

[0039] The hot air flowing into the connecting pipe 2 enters the countercurrent return air duct 8 through the connection of the corresponding corrugated hose 3, and then enters the drying box 9, and is dried by the refractory grade drying bag and refractory grade drying cotton board filled inside to remove the moisture generated in the drying process. Then the hot air can enter the air inlet of the fan 7 through the curved pipe 10 to complete the flow of airflow in the drying process. The return air has a certain amount of heat, which can reduce the heating time inside the heating box 6, which is beneficial to improving the energy saving of the equipment.

[0040] An ear seat 11 is fixedly welded on one side of the outer wall of the frame 15 of several circular drying baskets 1, and the ear seats 11 are rotatably connected through the column 12. A base bracket 13 is fixedly installed on the bottom of one of the circular drying baskets 1 at the bottom, and the bottom of the column 12 is fixedly welded to one side of the base bracket 13. An upper sealing plate 14 is fixedly installed on the top of one of the circular drying baskets 1 at the top, and a sealing ring is fixedly installed on the outer edge of the frame 15 between two adjacent circular drying baskets 1.

[0041] Since the frames 15 of several circular drying baskets 1 are rotatably connected through the ears 11 and the columns 12, when it is necessary to take out or place the refractory material inside a circular drying basket 1, it is only necessary to deflect the corresponding circular drying basket 1 as a whole, thereby reducing the impact on the other refractory materials being dried and improving the continuity of the refractory material drying process.

[0042] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
