Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a thermal circulation drying equipment for refractory brick production. Background Technology

[0002] In the production of refractory bricks, thermal circulation drying equipment plays a crucial role. Refractory bricks need to undergo a drying process to remove moisture in order to ensure their physical properties and quality. Thermal circulation drying equipment can utilize hot air circulation to dry refractory bricks efficiently and evenly, significantly improving drying efficiency and reducing drying time. This is of irreplaceable significance for improving production efficiency and ensuring product quality.

[0003] Currently, most common refractory brick production thermal circulation drying equipment uses a relatively traditional design for its racking system. The entire rack is constructed from a sturdy frame, and the spacing of the placement plates installed on the frame is fixed from the moment the equipment is manufactured, making subsequent adjustments impossible. During drying, hot air, driven by a fan, is forced from one side of the equipment to the other. Within this relatively fixed space, the hot air follows a simple principle of thermal convection, carrying away moisture from the refractory bricks placed on the fixed-spacing plates.

[0004] Fixed-size shelving structures cannot accommodate the placement requirements of various brick types, resulting in significant space waste and extremely low space utilization during the drying process. Furthermore, the inability to adjust the spacing between placement plates according to brick type hinders the even circulation of hot air among different brick types, impacting drying efficiency and effectiveness. Therefore, a thermal circulation drying device for refractory brick production is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a refractory brick production thermal circulation drying equipment, which aims to improve the existing technology where the traditional shelf size is fixed, making it difficult to meet the placement requirements of various brick types, resulting in low space utilization and unfavorable hot air circulation during the drying process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A refractory brick production thermal circulation drying equipment includes a drying chamber, a heat pump dryer fixedly connected to the side wall of the drying chamber, a dehumidification fan fixedly connected to the upper surface of the drying chamber, an air wall fixedly connected inside the drying chamber, a fixing component provided on the side wall of the air wall, and a placement component provided inside the drying chamber.

[0008] The placement assembly includes a placement plate, a support frame is provided inside the drying chamber, the placement plate is slidably connected between the support frames, a fixing rod is fixedly connected inside the support frame, a fixing block is fixedly connected to the side wall of the placement plate, a rotating plate is rotatably connected to the bottom of the placement plate, a connecting block is fixedly connected to the bottom of the placement plate, a handle is provided on the side wall of the connecting block, a locking post is fixedly connected to the side wall of the handle, the locking post is slidably connected inside the connecting block, a first spring is sleeved on the side wall of the locking post, and a recessed hole is provided inside the support frame;

[0009] As a further description of the above technical solution:

[0010] The fixing component includes a fixing column, and a dustproof frame is provided on the side wall of the wind wall. A locking block is fixedly connected to the side wall of the dustproof frame.

[0011] As a further description of the above technical solution:

[0012] A fixed frame is fixedly connected inside the wind wall, and a connecting rod is fixedly connected inside the fixed frame;

[0013] As a further description of the above technical solution:

[0014] The fixing post is slidably connected to the side wall of the connecting rod, and the fixing post is slidably connected inside the locking block;

[0015] As a further description of the above technical solution:

[0016] A second spring is sleeved on the side wall of the connecting rod. One end of the second spring is fixedly connected to the side wall of the fixed column, and the other end of the second spring is fixedly connected to the inside of the fixed frame.

[0017] As a further description of the above technical solution:

[0018] A connecting column is slidably connected inside the fixed frame, and a rotating rod is rotatably connected to the side wall of the connecting column;

[0019] As a further description of the above technical solution:

[0020] The rotating rod is rotatably connected to the side wall of the fixed column, and a pressing block is rotatably connected to the side wall of the connecting column.

[0021] As a further description of the above technical solution:

[0022] The fixing block is slidably connected to the side wall of the fixing rod, one end of the first spring is fixedly connected to the side wall of the handle, the other end of the first spring is fixedly connected to the side wall of the connecting block, and the locking pin is slidably connected inside the recess.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, pulling the handle causes the locking post to disengage from the recessed hole, thus removing the fixing of the placement plate. At the same time, the first spring is stretched, and rotating the rotating plate locks the handle, preventing the first spring from rebounding. At this time, the placement plate can be pulled to allow the fixing block to slide along the fixing rod to adjust the position. After adjustment, rotating the rotating plate to fit against the bottom of the placement plate, the handle is no longer obstructed, the first spring rebounds, and the locking post engages in the recessed hole, completing the fixing of the placement plate. This solves the problem that traditional fixed shelf dimensions are difficult to meet the placement needs of various brick types, resulting in low space utilization and unfavorable hot air circulation during the drying process. The above technical solution improves the drying effect and efficiency.

[0025] 2. In this utility model, pressing the pressing block moves the connecting column, causing the rotating rod to rotate and push the fixed column, making it slide along the side wall of the connecting rod, squeezing the second spring, causing the fixed column to disengage from the locking block, and releasing the fixation of the dustproof frame. Then, rotating the pressing block makes its side wall connecting block lock the fixed frame, preventing the second spring from rebounding, so the dustproof frame can be removed for cleaning. This solves the problem that the dustproof frame is fixed by bolts, and the installation and disassembly require tools, which is quite troublesome. The above technical solution improves the convenience of cleaning the dustproof frame. Attached Figure Description

[0034] 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.

[0035] Reference Figure 1 - Figure 4 This utility model provides an embodiment of a refractory brick production thermal circulation drying equipment, including a drying chamber 1, a heat pump dryer 2 fixedly connected to the side wall of the drying chamber 1, a dehumidifying fan 3 fixedly connected to the upper surface of the drying chamber 1, an air wall 4 fixedly connected inside the drying chamber 1, a fixing component provided on the side wall of the air wall 4, and a placement component provided inside the drying chamber 1; the placement component includes a placement plate 7, a support frame 5 provided inside the drying chamber 1, the placement plate 7 slidably connected between the support frames 5, a fixing rod 6 fixedly connected inside the support frame 5, a fixing block 8 fixedly connected to the side wall of the placement plate 7, and a bottom of the placement plate 7... A rotating plate 9 is rotatably connected to the part, and a connecting block 10 is fixedly connected to the bottom of the placement plate 7. A handle 11 is provided on the side wall of the connecting block 10, and a locking post 12 is fixedly connected to the side wall of the handle 11. The locking post 12 is slidably connected inside the connecting block 10. A first spring 13 is sleeved on the side wall of the locking post 12. The first spring 13 is used for rebound and reset. A recessed hole 14 is opened inside the support frame 5. A fixing block 8 is slidably connected to the side wall of the fixing rod 6. One end of the first spring 13 is fixedly connected to the side wall of the handle 11, and the other end of the first spring 13 is fixedly connected to the side wall of the connecting block 10. The locking post 12 is slidably connected inside the recessed hole 14.

[0036] When the distance between the placement plates 7 needs to be adjusted, the handle 11 facilitates the operator's pulling action. Pulling the handle 11 moves the locking pin 12 out of the recess 14. The locking pin 12, which originally engaged with the recess 14 to fix the position of the placement plate 7, is now released from its fixed state. The movement of the locking pin 12 stretches and deforms the first spring 13, which has an elastic restoring force and stores energy during its stretching deformation. At this time, rotating the rotating plate 9 locks the handle 11 in place, preventing the first spring 13 from rebounding and ensuring that the locking pin 12 remains disengaged from the recess 14. The position of the placement plate 7 can then be adjusted. Pulling the placement plate 7 causes the fixing block 8 to slide against the side wall of the fixing rod 6. The fixing block 8, in conjunction with the fixing rod 6, guides the placement plate 7 to move smoothly, ensuring the stability of the adjustment process. After adjustment, rotate the rotating plate 9 to fit the bottom of the placement plate 7. When the handle 11 is no longer blocked by the rotating plate 9, the first spring 13 rebounds and locks the locking post 12 into the recessed hole 14 for fixation. This stabilizes the placement plate 7 in the adjusted position, meets the requirements of different specifications of refractory bricks for the layer spacing, improves space utilization, facilitates the uniform circulation of hot air between the placement plates 7 with different spacing, and improves the drying effect and efficiency.

[0037] Reference Figure 5 and Figure 6 The fixing components include a fixing column 19, a dustproof frame 15 on the side wall of the air wall 4, the dustproof frame 15 is used to prevent dust from entering the equipment and affecting the operation of the equipment and the drying quality of the refractory bricks, a locking block 16 is fixedly connected to the side wall of the dustproof frame 15, a fixing frame 17 is fixedly connected inside the air wall 4, a connecting rod 18 is fixedly connected inside the fixing frame 17, the fixing column 19 is slidably connected to the side wall of the connecting rod 18, the fixing column 19 is slidably connected inside the locking block 16, a second spring 20 is sleeved on the side wall of the connecting rod 18, one end of the second spring 20 is fixedly connected to the side wall of the fixing column 19, the other end of the second spring 20 is fixedly connected inside the fixing frame 17, a connecting column 21 is slidably connected inside the fixing frame 17, a rotating rod 22 is rotatably connected to the side wall of the connecting column 21, the rotating rod 22 is rotatably connected to the side wall of the fixing column 19, and a pressing block 23 is rotatably connected to the side wall of the connecting column 21.

[0038] The dustproof frame 15 is designed to prevent dust from entering the equipment and affecting its operation and the drying quality of the refractory bricks. However, it accumulates dust over time. The pressing block 23 allows the operator to apply pressure. Pressing the pressing block 23 moves the connecting column 21, which transmits the force applied by the pressing block 23. The movement of the connecting column 21 causes the rotating rod 22 to rotate and push the fixed column 19, thus changing the direction of force transmission. This causes the fixed column 19 to slide against the side wall of the connecting rod 18, compressing the second spring 20. The second spring 20 is elastic and stores energy when compressed. This disengages the fixed column 19 from the locking block 16. The fixed column 19, which originally engaged with the locking block 16 to secure the dustproof frame 15, is now free from this constraint. Rotating the pressing block 23 then causes the side wall's locking plate to engage inside the fixed frame 17, preventing the second spring 20 from rebounding. This maintains the fixed column 19 disengaged from the locking block 16. The dust cover 15 was then removed and cleaned to ensure that it could continue to effectively prevent dust.

[0039] Working principle: When it is necessary to adjust the distance between the placement plates 7, pull the handle 11 to move the locking post 12 away from the recess 14, thus releasing the fixation of the placement plate 7. The movement of the locking post 12 causes the first spring 13 to stretch and deform. At this time, rotate the rotating plate 9 to lock the handle 11 and prevent the first spring 13 from rebounding. At this time, the position of the placement plate 7 can be adjusted. Pull the placement plate 7 to make the fixing block 8 slide on the side wall of the fixing rod 6. After adjustment, rotate the rotating plate 9 to fit against the bottom of the placement plate 7. The handle 11 loses the resistance of the rotating plate 9, and the first spring 13 rebounds to lock the locking post 12 into the recess 14 for fixation.

[0040] Dustproof frame 15 accumulates dust during prolonged use. Pressing the pressing block 23 moves the connecting post 21, causing the rotating rod 22 to rotate and push the fixing post 19. This causes the fixing post 19 to slide against the side wall of the connecting rod 18, squeezing the second spring 20 and disengaging the fixing post 19 from the locking block 16, thus releasing the fixation of the dustproof frame 15. Then, rotating the pressing block 23 causes the side wall locking plate to engage inside the fixing frame 17, preventing the second spring 20 from rebounding. Finally, the dustproof frame 15 can be removed for cleaning.

[0041] 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.
