Description

Technical Field

[0001] This utility model relates to the field of refractory material drying technology, and more specifically, to a drying equipment for rapidly and uniformly drying corrosion-resistant refractory materials. Background Technology

[0002] As key structural and functional materials in the industrial field, corrosion-resistant refractory materials must possess core properties such as high temperature resistance, corrosion resistance, and high strength. Their quality directly affects the safety, stability, and service life of industrial equipment. The drying process, as a critical step in the production process of corrosion-resistant refractory materials, plays a decisive role in the final performance of the materials. The development of rapid and uniform drying equipment is based on the industry's urgent need to improve material performance, optimize production efficiency, and upgrade processes.

[0003] In existing facilities, the drying of stacked refractory bricks is often insufficient and uneven. In addition, the moisture generated during the heating and drying process cannot be dried in time in the hot air, resulting in low overall drying efficiency of the equipment.

[0004] A search revealed that Chinese patent CN212619780U discloses a novel refractory material drying equipment. In this structure, hot air blown out from an industrial hot air blower passes through a moving flow equalization box, resulting in more uniform heating and improved drying efficiency and effectiveness of refractory bricks. Furthermore, the hot air from the insulation box circulates through a dehumidifier and the industrial hot air mechanism. Moist air blown out of the insulation box is promptly dried by the dehumidifier before re-entering the insulation box, further enhancing drying efficiency. A filter box is installed in front of the dehumidifier to filter the air from the insulation box, preventing any impact on the dehumidifier's lifespan. Additionally, the refractory bricks can be transported using a forklift via a carrying frame, saving manpower and improving work efficiency.

[0005] However, in actual use, although the structure improves heating uniformity by moving the flow equalization box, the hot air is only heated once by the industrial hot air blower. The temperature stability of the hot airflow is insufficient, and the drying efficiency is easily affected by heat loss. In addition, there are local uneven heating problems, resulting in insufficient drying or overheating. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a drying equipment for rapidly and uniformly drying corrosion-resistant refractory materials, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A drying equipment for rapidly and uniformly drying corrosion-resistant refractory materials includes a drying chamber body, a sealed chamber door connected to one side of the drying chamber body via a hinge, multiple mounting grooves opened on the inner wall of the drying chamber body, multiple first electric heating tubes fixedly installed inside the mounting grooves, and a drying mechanism provided on one side of the drying chamber body.

[0009] The drying mechanism includes a heat-insulating conveying pipe that runs through one side of the drying chamber body. An air pump is fixedly installed on one side of the heat-insulating conveying pipe. A heating box is installed through the output end of the heat-insulating conveying pipe. Multiple second electric heating tubes are fixedly installed inside the heating box.

[0010] A heat-insulating pipe is provided through the top of the heating box, and a distribution frame is fixedly provided on the inner wall of the drying box. One end of the distribution frame is connected to the heat-insulating pipe, and multiple air outlets are provided through the bottom of the distribution frame.

[0011] By adopting the above technical solutions, three-dimensional and efficient heating is achieved. Moreover, the dual heating combined with the uniform distribution of hot airflow greatly improves the drying speed and uniformity, ensuring the drying quality of corrosion-resistant refractory materials. At the same time, the heat preservation design reduces heat loss and improves energy utilization.

[0012] As a further description of the above technical solution: the inner wall of the drying oven body is provided with an installation mechanism, the installation mechanism includes a plurality of guide columns and support columns fixedly disposed on the inner wall of the drying oven body, and a storage frame is slidably disposed on the surface of the guide columns;

[0013] A positioning frame is slidably provided on the surface of the support column. One end of the positioning frame is connected to the surface of the storage frame. Multiple threaded grooves are opened on the surface of the support column. The threaded grooves and the positioning frame are locked together by bolts.

[0014] The storage frame has a storage frame mesh inserted inside, and a handle is fixedly installed on one side of the storage frame mesh. The surface of the positioning frame has a slot, and a limit block is inserted inside the slot.

[0015] By adopting the above technical solution, the height of the storage frame can be flexibly adjusted to adapt to materials of different specifications. Secondly, it is convenient to pick up and put down materials, and prevents them from shifting during drying. The overall structure can be flexibly adjusted and placed stably, improving the convenience of operation and the adaptability of the equipment.

[0016] As a further description of the above technical solution: a rotating rod is rotatably provided on one side of the sealed box door, and a retaining frame is fixedly provided on one side of the drying box body; the rotating rod and the retaining frame are locked together by bolts.

[0017] A handle is fixedly installed on one side of the sealed box door, an opening is provided on the surface of the sealed box door, an observation window is fixedly installed inside the opening, and a dehumidifier is installed through the top of the drying box body.

[0018] By adopting the above technical solutions, reliable sealing is achieved, heat loss is reduced, the handle facilitates opening and closing of the door, the observation window allows for real-time monitoring of the internal drying status, improving operational convenience, and the dehumidifier on the top of the drying chamber can promptly expel humid air, accelerate moisture evaporation, and ensure drying efficiency and material quality.

[0019] The technical effects and advantages of this utility model are as follows:

[0020] 1. By setting up a drying mechanism, compared with the existing technology, the air pump draws air into the drying chamber and sends it into the heating box through the insulated conveying pipe. The second electric heating tube then heats the air, which effectively improves the temperature stability and heat utilization efficiency of the hot airflow and avoids the heat loss of a single heating source. Moreover, the heated hot airflow is transported to the distribution frame through the insulated pipe and then blown evenly onto the material through multiple air outlets. Combined with the auxiliary heating of the first electric heating tube, multi-dimensional three-dimensional drying is achieved, which greatly improves the uniformity of material heating and solves the problem of insufficient drying or overheating in some areas. At the same time, the hot airflow circulation and the dehumidifier work together to accelerate the discharge of humid air and significantly shorten the drying cycle. This not only ensures the drying quality of the corrosion-resistant refractory materials but also improves production efficiency and reduces energy consumption costs.

[0021] 2. By setting up an installation mechanism, compared with existing technologies, operators can easily adjust the height of the storage frame by sliding the positioning frame on the support column, combined with the cooperation of the threaded groove and bolts. It can be flexibly adapted to the size and quantity of anti-corrosion and refractory materials to meet the drying needs of materials of different specifications. Secondly, the guide column provides stable support for the storage frame, ensuring the smoothness of sliding adjustment and avoiding shaking that affects the placement of materials. The storage frame mesh is conveniently connected by a pull handle and fixed with the limit block on the positioning frame, which not only facilitates the loading and unloading of materials, but also prevents the materials from shifting during the drying process, ensuring the uniformity of drying. The overall structural design simplifies the loading and unloading process, reduces operation time, and improves the equipment's adaptability to diversified production needs, indirectly improving production efficiency.

[0028] 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.

[0029] The embodiments disclosed in this application are as follows: Figure 1-5 The drying equipment shown includes a drying chamber body 1, a sealed door 2 connected to one side of the drying chamber body 1 via a hinge, multiple mounting slots are provided on the inner wall of the drying chamber body 1, multiple first electric heating tubes 3 are fixedly installed inside the mounting slots, and a drying mechanism is provided on one side of the drying chamber body 1.

[0030] The drying mechanism includes a heat-insulating conveying pipe 4 that runs through one side of the drying chamber body 1, an air pump 5 that is fixedly installed on one side of the heat-insulating conveying pipe 4, a heating box 6 that runs through the output end of the heat-insulating conveying pipe 4, and multiple second electric heating tubes 7 that are fixedly installed inside the heating box 6.

[0031] A heat insulation pipe 8 is provided through the top of the heating box 6, and a distribution frame 9 is fixedly provided on the inner wall of the drying box body 1. One end of the distribution frame 9 is connected to the heat insulation pipe 8, and multiple air outlets 10 are provided through the bottom of the distribution frame 9.

[0032] Multiple first electric heating tubes 3 in the mounting groove on the inner wall of the drying oven body 1 start working to initially heat the inside of the drying oven body 1. At the same time, the drying mechanism starts and the air pump 5 starts working to draw in the air inside the drying oven body 1 and deliver it to the heating box 6 through the heat-insulating conveying pipe 4. Multiple second electric heating tubes 7 inside the heating box 6 reheat the incoming air to form a hot airflow.

[0033] The heated airflow is delivered through the heat insulation pipe 8 that runs through the top of the heating box 6 to the distribution frame 9 that is fixed on the inner wall of the drying oven body 1. After the hot airflow is dispersed in the distribution frame 9, it is evenly blown onto the anti-corrosion and refractory material on the storage frame mesh 16 through multiple air outlets 10 that run through the bottom of the distribution frame 9, so as to heat and dry the material in a comprehensive and uniform manner.

[0034] During the drying process, the moisture in the corrosion-resistant refractory material evaporates, causing the humidity inside the drying chamber 1 to rise. At this time, the dehumidifier 23 installed through the top of the drying chamber 1 is activated to expel the humid air inside, reduce the internal humidity, and speed up the drying process.

[0035] Reference Figure 2-3 As shown, the inner wall of the drying oven body 1 is provided with an installation mechanism, which includes multiple guide columns 11 and support columns 12 fixedly installed on the inner wall of the drying oven body 1. A storage frame 13 is slidably installed on the surface of the guide columns 11.

[0036] A positioning frame 14 is slidably provided on the surface of the support column 12. One end of the positioning frame 14 is connected to the surface of the storage frame 13. Multiple threaded grooves 15 are opened on the surface of the support column 12. The threaded grooves 15 and the positioning frame 14 are locked together by bolts.

[0037] The storage frame 13 has a storage frame mesh 16 inserted inside, and a pull handle 17 is fixedly installed on one side of the storage frame mesh 16. The surface of the positioning frame 14 has a slot, and a limit block 18 is inserted inside the slot.

[0038] The operator loosens the bolt between the rotating rod 19 and the card frame 20, then rotates the rotating rod 19, and then grasps the handle 21 on one side of the sealing box door 2 to open the sealing box door 2;

[0039] Furthermore, based on the size and quantity of the anti-corrosion and refractory materials to be dried, the position of the storage frame 13 is adjusted. After adjusting the position of the sliding positioning frame 14 on the support column 12 to a suitable height, the positioning frame 14 is locked with the corresponding threaded groove 15 on the surface of the support column 12 using bolts, thereby fixing the position of the storage frame 13. Since one end of the positioning frame 14 is connected to the surface of the storage frame 13, and the storage frame 13 is slidably set on the surface of the guide column 11, this ensures that the storage frame 13 is stably installed.

[0040] Next, insert the storage frame mesh 16 into the storage frame 13 through the pull handle 17 on one side. Then, insert the limiting block 18 into the slot on the surface of the positioning frame 14 to limit and fix the storage frame mesh 16, preventing it from moving during the drying process. Then, place the anti-corrosion and refractory material to be dried evenly on the storage frame mesh 16.

[0041] Reference Figure 4-5 As shown, a rotating rod 19 is rotatably installed on one side of the sealed door 2, and a clamping frame 20 is fixedly installed on one side of the drying box body 1. The rotating rod 19 and the clamping frame 20 are locked together by bolts.

[0042] A handle 21 is fixedly installed on one side of the sealed box door 2. An opening is provided on the surface of the sealed box door 2. An observation window 22 is fixedly installed inside the opening. A dehumidifier 23 is installed through the top of the drying box body 1.

[0043] Close the sealed box door 2, rotate the rotating rod 19, and lock the rotating rod 19 with the clamp frame 20 with bolts to ensure that the sealed box door 2 is well sealed. The operator can observe the internal drying situation at any time through the observation window 22 fixed in the opening on the surface of the sealed box door 2. During the drying process, the moisture in the anti-corrosion refractory material evaporates, causing the humidity inside the drying box body 1 to rise. At this time, the dehumidifier 23 installed through the top of the drying box body 1 is activated to exhaust the humid air inside, reduce the internal humidity, and speed up the drying process.

[0044] The operator monitors the drying status of the corrosion-resistant refractory material in real time through the observation window 22. When the corrosion-resistant refractory material is observed to have reached the drying requirements, the power supply of the equipment is turned off, and the first electric heating tube 3, the second electric heating tube 7, the air pump 5 and the dehumidifier 23 stop working.

[0045] After the internal temperature of the drying oven body 1 drops to a suitable level, loosen the bolts between the rotating rod 19 and the clamping frame 20, open the sealed oven door 2, and use the pull handle 17 to take out the dried anti-corrosion and refractory material along with the storage frame mesh 16 from the storage frame 13 to complete the entire drying process.

[0046] Working principle of this utility model:

[0047] This utility model is a drying equipment for quickly and uniformly drying anti-corrosion refractory materials. When using the device, the operator loosens the bolt between the rotating rod 19 and the clamping frame 20, then rotates the rotating rod 19, and then holds the handle 21 on one side of the sealed box door 2 to open the sealed box door 2.

[0048] Furthermore, based on the size and quantity of the anti-corrosion and refractory materials to be dried, the position of the storage frame 13 is adjusted. After adjusting the position of the sliding positioning frame 14 on the support column 12 to a suitable height, the positioning frame 14 is locked with the corresponding threaded groove 15 on the surface of the support column 12 using bolts, thereby fixing the position of the storage frame 13. Since one end of the positioning frame 14 is connected to the surface of the storage frame 13, and the storage frame 13 is slidably set on the surface of the guide column 11, this ensures that the storage frame 13 is stably installed.

[0049] Next, insert the storage frame mesh 16 into the storage frame 13 through the pull handle 17 on one side. Then, insert the limiting block 18 into the slot on the surface of the positioning frame 14 to limit and fix the storage frame mesh 16, preventing it from moving during the drying process. Then, place the anti-corrosion and refractory material to be dried evenly on the storage frame mesh 16.

[0050] Then close the sealed box door 2, rotate the rotating rod 19, and lock the rotating rod 19 with the clamp frame 20 by bolts to ensure that the sealed box door 2 is well sealed. The operator can observe the internal drying situation at any time through the observation window 22 fixedly set in the opening on the surface of the sealed box door 2.

[0051] Multiple first electric heating tubes 3 in the mounting groove on the inner wall of the drying oven body 1 start working to initially heat the inside of the drying oven body 1. At the same time, the drying mechanism starts and the air pump 5 starts working to draw in the air inside the drying oven body 1 and deliver it to the heating box 6 through the heat-insulating conveying pipe 4. Multiple second electric heating tubes 7 inside the heating box 6 reheat the incoming air to form a hot airflow.

[0052] The heated airflow is delivered through the heat insulation pipe 8 that runs through the top of the heating box 6 to the distribution frame 9 that is fixed on the inner wall of the drying oven body 1. After the hot airflow is dispersed in the distribution frame 9, it is evenly blown onto the anti-corrosion and refractory material on the storage frame mesh 16 through multiple air outlets 10 that run through the bottom of the distribution frame 9, so as to heat and dry the material in a comprehensive and uniform manner.

[0053] During the drying process, the moisture in the anti-corrosion refractory material evaporates, causing the humidity inside the drying chamber 1 to rise. At this time, the dehumidifier 23 installed through the top of the drying chamber 1 is activated to exhaust the humid air inside, reduce the internal humidity, and speed up the drying process. The dehumidifier 23 is a model RY-8240GS dehumidifier, which is existing technology and will not be described in detail in this technical solution.

[0054] The operator monitors the drying status of the corrosion-resistant refractory material in real time through the observation window 22. When the corrosion-resistant refractory material is observed to have reached the drying requirements, the power supply of the equipment is turned off, and the first electric heating tube 3, the second electric heating tube 7, the air pump 5 and the dehumidifier 23 stop working.

[0055] After the internal temperature of the drying oven body 1 drops to a suitable level, loosen the bolts between the rotating rod 19 and the clamping frame 20, open the sealed oven door 2, and use the pull handle 17 to take out the dried anti-corrosion and refractory material along with the storage frame mesh 16 from the storage frame 13 to complete the entire drying process.

[0056] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
