Description

Technical Field

[0001] This utility model relates to the technical field of refractory material calcination equipment, and in particular to a high-temperature refractory material calcination device. Background Technology

[0002] In the field of refractory material production, efficient and high-quality calcination processes are crucial. With the development of the industry, various types of refractory material calcination equipment are constantly emerging.

[0003] In the prior art, Chinese utility model patent application number CN201921351187.4 discloses a refractory brick firing device. This device includes a main body base with two support pads fixedly installed on the left and right sides of the bottom of the base. A firing box is fixedly installed on the top. A transmission groove is set inside the main body base, and meshing transmission gears and receiving gears within the groove drive the transmission gears to rotate when the power motor is running. This, in turn, drives the transmission shaft and rotating mounting plate to rotate at a uniform speed, ensuring uniform heating of the bricks to be processed during firing. The bottom wall of the mounting chute is provided with ball bearing mounting grooves corresponding to stainless steel moving ball bearings, making the firing mounting plate easy to store and place, significantly reducing the difficulty of installation and disassembly. However, this technology has the following drawbacks: Firstly, refractory bricks are usually stacked in the placement groove for firing, and the inner surface of the stacked refractory bricks cannot be fully heated, making it difficult to achieve the ideal effect of uniform heating. Secondly, the firing mounting plate lacks effective measures to fix the refractory bricks, making them prone to falling during material handling.

[0004] In summary, how to avoid uneven heating of refractory bricks during the refractory brick firing process and prevent refractory bricks from falling off during material handling is a key concern. Therefore, we propose a high-temperature refractory material firing device to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature refractory material calcination device. By using this device, the problems in the background art mentioned above can be solved.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: a high-temperature refractory material calcination device, comprising a calcination box, a rotating seat rotatably connected to the bottom wall of the calcination box, a heating component provided on the inner side wall of the calcination box, a top cover hinged to the top of the calcination box, a placement cylinder detachably connected to the top of the rotating seat, a first traction hook installed at the top of the placement cylinder, and multiple layers of placement structures arranged in a circumferential array fixedly installed on the side wall of the placement cylinder, the placement structure comprising three placement plates arranged side by side, each placement plate having multiple evenly distributed blocks, a bearing plate fixedly connected to the bottom of the placement cylinder, and a unloading mechanism sleeved on the outside of the placement cylinder, the unloading mechanism contacting the bearing plate.

[0007] Preferably, the outer sides of the placement plates on both sides of the placement structure are provided with L-shaped blocks that are the same number as the number of blocks and are evenly distributed.

[0008] Preferably, each side wall of the placement cylinder is provided with two rows of placement structures.

[0009] Preferably, the first traction hook is installed at the center of the top of the placement cylinder.

[0010] Preferably, each of the two corresponding sidewalls of the placement cylinder is provided with a guide groove, and the guide groove is located between the two rows of placement structures.

[0011] Preferably, the unloading mechanism includes an unloading frame, inside which are arranged multiple unloading plates and a first support plate. The unloading plates are located between adjacent placement plates within the placement structure, and the first support plate is located between placement structures on the same side wall of the placement cylinder. An L-shaped connecting rod is slidably connected in the guide groove. The bottom end of the connecting rod is fixedly connected to the top end of the first support plate away from the unloading frame. A second traction hook is arranged between the connecting rods and above the first traction hook. An anti-detachment component is provided inside the unloading frame.

[0012] Preferably, the anti-detachment component includes a first stop bar, a second stop bar, a third stop bar, and a baffle plate. The first stop bar is fixedly connected to the top of the unloading frame and corresponds to the position of the placement plate. The second stop bar is fixedly connected to the top of the unloading plate at the end away from the unloading frame. Inside the unloading frame, a right-angled second support plate is provided between the placement structures of adjacent side walls of the placement cylinder. The top of the second support plate has a threaded hole corresponding to the position of the stop bar. The surface of the third stop bar is threadedly connected to the threaded hole. The baffle plate is fixedly connected to the top of the unloading frame.

[0013] Preferably, a reinforcing rib is fixedly connected between the bottom end of the placement plate and the side wall of the placement cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. Effectively solves the problem of uneven heating of refractory materials. The placement cylinder has a multi-layered, circumferentially arrayed placement structure on its side wall. Each placement structure includes three side-by-side placement plates, and each placement plate has multiple evenly distributed baffles, dividing the placement area into multiple independent small spaces for placing refractory materials. During the firing process, the rotating seat drives the placement cylinder to rotate, allowing each piece of refractory material to receive heat radiation from the heating components on the inner side wall of the firing chamber from all directions. Compared with the existing technology of stacking refractory bricks in the placement trough, this method ensures that each piece of refractory material is fully heated, achieving the ideal effect of uniform heating and greatly improving the firing quality of refractory materials.

[0016] 2. To prevent refractory materials from falling during the material handling process, letter-shaped limit rods, the same number as the number of stop blocks, are evenly distributed on the outer side of the placement plates on both sides of the placement structure. These effectively prevent the refractory materials from shifting or even falling off during placement and firing. Simultaneously, the unloading mechanism is equipped with anti-detachment components, including a first stop rod, a second stop rod, a third stop rod, and a baffle plate. During unloading, these anti-detachment components work together to surround the refractory materials placed on the placement structure, preventing them from falling during lifting. This ensures the safety and reliability of the material handling process, effectively solving the problems existing in the prior art and improving the convenience and safety of operation.

Detailed Implementation

[0024] 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.

[0025] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0026] Combination Figures 1-6 A high-temperature refractory material calcination apparatus includes a calcination chamber 1. A rotating seat 2 is rotatably connected to the bottom wall of the calcination chamber 1 to provide rotational support for a placement cylinder 5. A heating component 3 is installed on the inner side wall of the calcination chamber 1 to create a high-temperature calcination environment. A top cover 4 is hinged to the top of the calcination chamber 1 for easy opening and closing, facilitating material loading and unloading and maintaining the temperature inside the chamber. A placement cylinder 5 with an isometric rectangular parallelepiped structure is inserted into the top of the rotating seat 2. A first traction hook 6 is installed at the top of the placement cylinder 5 for easy lifting and placement by the operator. Multiple layers of placement cylinders arranged in a circular array are fixedly installed on the side wall of the placement cylinder 5. The placement structure 7 is used to support refractory materials. The placement structure 7 includes three side-by-side placement plates 8. Each placement plate 8 is provided with multiple evenly distributed baffles 9, which divide the placement plate 8 into multiple independent small areas. This can effectively prevent the refractory materials from being squeezed and collided with each other during placement and firing, and ensure that each piece of material can be heated evenly. The bottom end of the placement cylinder 5 is fixedly connected to the support plate 11. The placement cylinder 5 is sleeved with a discharge mechanism 10, which is used to smoothly discharge the refractory materials after firing, and ensure that the refractory materials will not fall off due to various reasons during the discharge process. The discharge mechanism 10 is in contact with the support plate 11.

[0027] The outer sides of the placement plates 8 on both sides of the placement structure 7 are provided with L-shaped limiting rods 12, which are the same number as the baffles 9 and are evenly distributed. The limiting rods 12 work together with the baffles 9. The limiting rods 12 further restrict the displacement of the refractory material from both sides, preventing it from sliding off the sides of the placement structure 7 when the placement cylinder 5 rotates, thus ensuring the stability of the refractory material during the placement and firing process in all aspects.

[0028] A reinforcing rib 13 is fixedly connected between the bottom end of the placement plate 8 and the side wall of the placement cylinder 5, which enhances the overall strength and stability of the placement structure 7.

[0029] Each side wall of the placement cylinder 5 is provided with two rows of placement structures 7.

[0030] The first traction hook 6 is installed at the center of the top of the placement cylinder 5, which allows for better balance when lifting or lowering the placement cylinder 5.

[0031] The placement cylinder 5 has guide grooves 14 on two corresponding side walls. The guide grooves 14 are located between the two rows of placement structures 7. The guide grooves 14 cooperate with the letter connecting rods 104 in the unloading mechanism 10 and play a precise guiding role in the installation and unloading operation of the unloading mechanism 10.

[0032] The unloading mechanism 10 includes an unloading frame 101, inside which are arranged multiple unloading plates 102 and a first support plate 103. The unloading plates 102 are located between adjacent placement plates 8 within the placement structure 7, and the first support plate 103 is located between placement structures 7 on the same side wall of the placement cylinder 5. An L-shaped connecting rod 104 is slidably connected in the guide groove 14. The bottom end of the connecting rod 104 is fixedly connected to the top end of the first support plate 103 away from the unloading frame 101. A second traction hook 105 is arranged between the connecting rods 104 and above the first traction hook 6. An anti-detachment component 106 is arranged inside the unloading frame 101. By pulling the second traction hook 105, the connecting rod 104 drives the unloading plate 102 to push out the calcined refractory material on the placement plate 8 during the movement, thereby realizing the unloading operation. The anti-detachment component 106 prevents the refractory material from falling accidentally during the unloading process.

[0033] The anti-detachment component 106 includes a first stop 1061, a second stop 1062, a third stop 1063, and a baffle 1064. The first stop 1061 is fixedly connected to the top of the unloading frame 101 and corresponds to the position of the placement plate 8. The second stop 1062 is fixedly connected to the top of the unloading plate 102 at the end away from the unloading frame 101. Inside the unloading frame 101, between the placement structures 7 on the adjacent side walls of the placement cylinder 5, a right-angled second support plate 1065 is provided. The top of the second support plate 1065 has a threaded hole corresponding to the position of the stop block 9. The surface of the third stop 1063 is threadedly connected to the threaded hole. The baffle 1064 is fixedly connected to the top of the first support plate 103. When unloading, the first stop 1061, the second stop 1062, the third stop 1063, and the baffle 1064 work together to surround the refractory material placed on the placement structure 7, preventing it from falling during the lifting process and ensuring the safety and reliability of the material handling process.

[0034] Working principle:

[0035] Select the unloading mechanism 10 without the third stop 1063 installed and place it on the support plate 11 at the bottom of the placement cylinder 5. During placement, the connecting rod 104 slides along the guide groove 14 on the side wall of the placement cylinder 5. The guide groove 14 is between the two rows of placement structures 7 to ensure that the unloading mechanism 10 is accurately positioned. Then, after the refractory material is placed into the placement structure 7 on the side of the placement structure 8, the third stop 1063 is threaded into the threaded hole at the top of the second support plate 1065. Each side wall of the placement cylinder 5 has two rows of placement structures 7 arranged in a circumferential array. Each placement structure 7 consists of three side-by-side placement plates 8. The plates are evenly distributed with baffles 9 to separate independent areas for placing materials, ensuring uniform heating. The limiting rods 12 outside the placement plates 8 on both sides prevent the materials from shifting and falling off. The first traction hook 6 at the center of the top of the placement cylinder 5 is hooked by a crane, and the placement cylinder 5, the unloading mechanism 10 and the refractory material are hoisted to the roasting box 1, so that the placement cylinder 5 and the rotating seat 2 are connected by insertion, ensuring the transmission connection between the placement cylinder 5 and the rotating seat 2.

[0036] After the placement cylinder 5 is installed, the top cover 4 of the roasting box 1 is closed to form a closed space, which is conducive to temperature control and heat concentration. The heating component 3 is turned on to quickly raise the temperature for roasting. At the same time, the motor drives the synchronous wheel and the synchronous belt transmission mechanism to drive the rotating seat 2 to rotate smoothly, and the placement cylinder 5 rotates accordingly. Because the placement structure 7 is circumferentially distributed, the refractory material is heated in all directions, avoiding the uneven heating of traditional stacking. The reinforcing ribs 13 between the placement plate 8 and the side wall 9 of the placement cylinder enhance the structural stability and ensure roasting safety.

[0037] After the roasting is completed, the top cover 4 is opened, the crane hooks the second traction hook 105 to lift it, the connecting rod 104 slides in the guide groove 14, driving the unloading mechanism 10 to detach from the placement cylinder 5 and be lifted out. The anti-detachment component 106 in the unloading mechanism 10 covers the refractory material to prevent the refractory material from falling off.

[0038] The unloading mechanism 10 and the refractory material are moved to the cooling zone. Since the refractory material is prone to cracking when cooled suddenly, natural cooling or heat insulation cover is used to allow the heat to dissipate slowly and ensure the material performance. The crane is used to hook the first traction hook 6 and take out the placement cylinder 5. Since the material of the placement cylinder 5 has good thermal stability, it can be cooled quickly by air cooling or water cooling and put into the next round of loading as soon as possible. After one round of operation, the rapidly cooled placement cylinder 5 is placed and a new unloading mechanism 10 is installed. The loading, firing, unloading and cooling process is repeated. By using two unloading mechanisms alternately, the production efficiency is improved.
