Description

Technical Field

[0001] This utility model relates to the field of calcining furnace technology, and in particular to a modular assembly calcining furnace rapid inspection and maintenance structure. Background Technology

[0002] A calcining furnace is an industrial device that uses high-temperature heating to cause physical or chemical changes in materials. Essentially, it is a key piece of equipment that utilizes thermal energy to improve the properties of materials. It typically consists of components such as a furnace body, heating system, transmission device, and temperature control system, and can be designed as a fixed type (such as a box furnace) or a rotating type (such as a rotary kiln) according to process requirements.

[0003] In traditional calcining furnaces, ore is usually added directly to the furnace tubes for calcination. Due to the different particle sizes of the ore, large pieces of ore have a small heating area and slow heat conduction, resulting in a large difference in the calcination progress between the inner and outer layers. It often takes a longer time to complete the reaction. In order to ensure the calcination effect, the overall calcination time can only be passively extended, which affects production efficiency and increases energy consumption costs.

[0004] In response to the technical problem that direct calcination of uncrushed ore affects production efficiency and increases energy costs, this application proposes a modular assembly calcining furnace rapid inspection and maintenance structure. Utility Model Content

[0005] The purpose of this invention is to address the drawbacks of directly calcining uncrushed ore, which affects production efficiency and increases energy costs. The proposed invention is a modular, assembled calcining furnace rapid inspection and maintenance structure. By moving a plate, the clamping block disengages from the slot inside the fixed block, thus eliminating the need to fix the crushing box. This allows the crushing box to be removed for easy maintenance, improving repair efficiency. Furthermore, the crushing teeth pulverize the calcined ore, enhancing the efficiency of subsequent calcination.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular assembly-type calcining furnace rapid inspection and maintenance structure, including a calcining furnace body, a furnace tube rotatably connected to the inner wall of the calcining furnace body, a support plate fixedly connected to the right end of the calcining furnace body, a crushing box provided at the top of the support plate, a bidirectional screw rotatably connected to the inner wall of the support plate, the bidirectional screw being connected to the crushing box through a fixing assembly, a drive shaft rotatably connected to the inner wall of the crushing box, the drive shaft being connected to a driven shaft through a gear assembly, and multiple crushing teeth fixedly connected to the outer walls of both the drive shaft and the driven shaft.

[0007] Furthermore, the fixing component includes movable blocks threadedly connected to both sides of the outer wall of the bidirectional screw, the outer walls of the movable blocks being fixedly connected to the inner wall of the support plate, and a locking block being fixedly connected to one opposite end of each movable block.

[0008] Furthermore, fixing blocks are fixedly connected to both the front and rear sides of the bottom of the crushing box, and the inner wall of each fixing block is provided with a slot, the shape of which matches the slot.

[0009] Furthermore, a crank handle is fixedly connected to the front end of the bidirectional screw to drive the bidirectional screw to rotate.

[0010] Furthermore, the gear assembly includes a master gear fixedly connected to the outer wall of the drive shaft, a driven gear meshing with the outer wall of the master gear, and the outer wall of the driven shaft fixedly connected to the inner wall of the driven gear.

[0011] Furthermore, a first motor is fixedly connected to the right end of the crushing box, and the right end of the drive shaft is fixedly connected to the drive end of the first motor.

[0012] Furthermore, a second motor is fixedly connected to the top of the support plate, and a first sprocket is fixedly connected to the drive end of the second motor. The first sprocket is connected to the second sprocket via a chain, and the inner wall of the second sprocket is fixedly connected to the outer wall of the furnace tube.

[0013] Furthermore, the left end of the crushing box is fixedly connected to the discharge pipe, and the discharge pipe is located on the inner wall of the furnace tube.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by rotating the bidirectional screw, the moving plates on both sides are moved, and the moving plates cause the locking block to disengage from the locking groove inside the fixing block, thereby removing the fixing of the crushing box. The crushing box can be removed for easy maintenance and to improve maintenance efficiency.

[0016] 2. In this utility model, the motor drives the drive shaft to rotate, and the drive shaft drives the driven shaft to rotate through the main gear and the driven gear, so that the crushing teeth on both sides crush the ore, making the crushed ore easier to calcine in the furnace tube and improving the calcination efficiency of the furnace tube.

Detailed Implementation

[0023] 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.

[0024] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a modular assembly-type calcining furnace rapid inspection and maintenance structure, including a calcining furnace body 1, a furnace tube 17 rotatably connected to the inner wall of the calcining furnace body 1, a support plate 2 fixedly connected to the right end of the calcining furnace body 1, a crushing box 7 set at the top of the support plate 2, a bidirectional screw 4 rotatably connected to the inner wall of the support plate 2, moving blocks 5 threadedly connected to both sides of the outer wall of the bidirectional screw 4, the outer walls of the moving blocks 5 fixedly connected to the inner wall of the support plate 2, a locking block 6 fixedly connected to the opposite end of the moving blocks 5, fixing blocks 8 fixedly connected to both the front and rear sides of the bottom end of the crushing box 7, a locking groove 9 opened on the inner wall of the fixing block 8, the locking block 6 and the locking groove 9 are fitted in shape, and a crank 3 fixedly connected to the front end of the bidirectional screw 4 for driving the bidirectional screw 4 to rotate.

[0025] Specifically, a control console is installed at the front end of the calcining furnace body 1. The control console controls the calcining furnace body 1, the first motor 10, and the second motor 18 via electrical connection. The calcining furnace body 1 is equipped with an iron-chromium-aluminum heating wire. When the iron-chromium-aluminum heating wire is energized, it generates a large amount of heat, thereby heating the furnace tube 17. When installing the crushing box 7, first, the inclined discharge pipe 16 of the crushing box 7 is inserted into the furnace tube 17. Then, the fixing block 8 at the bottom of the crushing box 7 is inserted into the support plate 2. Then, the crank handle 3 is turned to drive the bidirectional screw 4 to rotate, thereby moving the moving blocks 5 on both sides to the sides. The moving blocks 5 drive the locking block 6 into the locking slot 9 to fix the crushing box 7.

[0026] Reference Figure 3 and Figure 4 The inner wall of the crushing box 7 is rotatably connected to the drive shaft 11. The outer wall of the drive shaft 11 is fixedly connected to the main gear 12. The outer wall of the main gear 12 is meshed with the driven gear 13. The outer wall of the driven shaft 14 is fixedly connected to the inner wall of the driven gear 13. The right end of the crushing box 7 is fixedly connected to the first motor 10. The right end of the drive shaft 11 is fixedly connected to the drive end of the first motor 10. Multiple crushing teeth 15 are fixedly connected to the outer walls of both the drive shaft 11 and the driven shaft 14. The top of the support plate 2 is fixedly connected to the second motor 18. The drive end of the second motor 18 is fixedly connected to the first sprocket 19. The first sprocket 19 is connected to the second sprocket 20 through a chain. The inner wall of the second sprocket 20 is fixedly connected to the outer wall of the furnace tube 17. The left end of the crushing box 7 is fixedly connected to the discharge pipe 16, which is located on the inner wall of the furnace tube 17.

[0027] Specifically, the furnace tube 17 is tilted to the left as a whole, with the left side being lower and the right side being higher. The tilt is lower and smaller. The discharge pipe 16 is located on the inner wall of the right side of the furnace tube 17. When the furnace tube 17 rotates, it will not contact the outer wall of the discharge pipe 16. The top of the calcining furnace body 1 is installed with bolts. The furnace tube 17 inside can be maintained by removing the bolts.

[0028] Working principle: During use, the calcined ore is added into the crushing box 7 from the top. Simultaneously, the first motor 10 is started, driving the drive shaft 11 to rotate. The drive shaft 11 then drives the main gear 12, which in turn drives the driven gear 13, causing the driven shaft 14 to rotate. This causes multiple crushing teeth 15 on the outer walls of the drive shaft 11 and driven shaft 14 to rotate, crushing the ore. The crushed ore enters the furnace tube 17 through the discharge pipe 16 on the left. The calcining furnace body 1 is then started to heat the furnace tube 17. Simultaneously, the second motor 18 is started. Motor 18 drives the first sprocket 19 to rotate, and the first sprocket 19 drives the second sprocket 20 to rotate via a chain. The second sprocket 20 then drives the furnace tube 17 to rotate, causing the ore inside the furnace tube 17 to slowly move to the left until it exits from the left end of the furnace tube 17. When maintaining the crushing box 7 later, the crank handle 3 can be turned, which drives the double-sided screw 4 to rotate. The double-sided screw 4 then drives the moving blocks 5 on both sides to move towards the middle, thereby causing the locking block 6 to disengage from the locking groove 9 inside the fixing block 8, thus removing the restriction on the crushing box 7 and allowing the crushing box 7 to be removed for easy maintenance.

[0029] 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.
