Description

Technical Field

[0001] The utility model relates to the technical field of roller hearth kiln construction, and more specifically to a high-strength roller rod for preparing foam glass plates. Background Art

[0002] When preparing foam glass plates, an annealing kiln or an archless kiln is required. The archless kiln is a tunnel kiln with a long and narrow cross-section. Different from the kiln car tunnel kiln, it does not use the kiln car loaded with products to run, so the kiln top structure is a flat ceiling type. A "roller path" is composed of a series of rollers arranged in parallel and crossing the cross-section of the kiln working channel. The products are placed on the roller path and are conveyed into the kiln as the rollers rotate, and the firing process is completed in the kiln. The temperature in the kiln is uniform, which is suitable for rapid firing, but the requirements for the roller material and installation technology are relatively high. Rollers are required inside both the annealing kiln and the archless kiln.

[0003] In the prior art, when preparing foam glass plates, the raw materials of the foam glass plates are conveyed by rotating roller rods. Larger and heavier materials are conveyed above the existing roller rods, and the original roller rods have problems such as insufficient strength. After long-term use, the inside of the roller rods will overheat and cracks will appear inside. Moreover, when the roller rods are working, they need to rotate for a long time, and the connecting parts of the rotating bearings on both sides will become loose, resulting in the roller rods moving left and right during rotation. Therefore, a high-strength roller rod for preparing foam glass plates is designed to solve the above problems. Summary of the Utility Model

[0004] In order to overcome the above defects of the prior art, the utility model provides a high-strength roller rod for preparing foam glass plates to solve the problems existing in the above background art.

[0005] The utility model provides the following technical solution: A high-strength roller rod for preparing foam glass plates includes an outer rod. An inner rod is arranged inside the outer rod. Connecting pieces are fixedly connected to both ends of the inner rod and the outer rod. The cross-section of the connecting piece is in a concentric circle structure. A number of ventilation holes are arranged inside the connecting piece. A number of lower connecting plates are fixedly connected to the outer side of the inner rod. Springs are fixedly connected to the upper ends of the lower connecting plates, and the upper ends of the springs are fixedly connected to the lower ends of the upper connecting plates. The other side of the upper connecting plate is fixedly connected to the inside of the outer rod. The inner rod, the outer rod and the connecting piece form a roller rod body.

[0006] Preferably, the materials of the inner rod, the outer rod and the connecting piece are all ceramic materials.

[0007] Preferably, a plug-in groove is fixedly connected to the outer side of the outer rod. The outer side of the plug-in groove is inserted into the inside of a rotating piece. Symmetrically distributed clamping grooves are arranged on both sides of the outer side of the rotating piece. A plug-in hole is arranged in the middle of the outer side of the rotating piece. The outer side of the rotating piece is rotatably connected to the rotating bearing inside the track kiln.

[0008] Preferably, the inner surface of the outer rod is a heat-resistant layer, and an anti-corrosion layer is adhered inside the heat-resistant layer, and a reinforcement layer is adhered inside the anti-corrosion layer.

[0009] Preferably, the inner coatings of the outer rod are adhered by high-temperature glue.

[0010] Preferably, the spring is made of high-temperature resistant material.

[0011] The technical effects and advantages of the present utility model:

[0012] 1. By arranging an inner rod inside the outer rod of the present utility model, and connecting the inner rod and the outer rod with connectors having ventilation holes on both sides, the hardness of the roller rod composed of the inner rod and the outer rod can be strengthened, the load-bearing strength can be improved, and the connectors on both sides can also play a role in ventilation and heat dissipation during movement, avoiding the situation that the inside of the hollow roller rod overheats and cracks, prolonging the service life, and ensuring the normal conveying of materials inside the tunnel kiln.

[0013] 2. By designing both the inner rod and the outer rod constituting the roller rod as ceramic materials, the present utility model can achieve the effect of high temperature resistance.

[0019] The technical solutions in the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the present utility model. In addition, the forms of the various structures described in the following embodiments are merely examples, and the novel structures involved in the present utility model are not limited to the various structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0020] The present utility model provides a high-strength roller rod for preparing foam glass plates, which includes an outer rod 1. An inner rod 3 is arranged inside the outer rod 1. Connecting pieces 4 are fixedly connected to both ends of the inner rod 3 and the outer rod 1. The cross-section of the connecting piece 4 is in a concentric circle structure. A plurality of ventilation holes 5 are arranged inside the connecting piece 4. A plurality of lower connecting plates 6 are fixedly connected to the outer side of the inner rod 3. Springs 7 are fixedly connected to the upper ends of the lower connecting plates 6. The upper ends of the springs 7 are fixedly connected to the lower end of the upper connecting plate 8. The other side of the upper connecting plate 8 is fixedly connected inside the outer rod 1. The inner rod 3, the outer rod 1 and the connecting piece 4 form a roller rod body.

[0021] Furthermore, the materials of the inner rod 3, the outer rod 1 and the connecting piece 4 are all ceramic materials. By utilizing the heat resistance of the ceramic materials, it is ensured that the rod body can work inside the tunnel kiln for a long time, avoiding the situation that cracks appear on the surface due to excessive heat inside and outside the rod body. The ventilation holes 5 inside the connecting piece 4 connected to both sides of the inner rod 3 are used to dissipate the heat inside the outer rod 1, avoiding the accumulation of heat inside the outer rod 1. When a heavy object moves on the rod, the pressure received by the outer rod 1 is buffered by the internal spring 7. The force received is transferred to the other side surface of the outer rod 1 and the inner rod 3 by another spring 7, playing a certain role in force buffering, avoiding the situation that the contact position of the rod itself is bent or the feeding cannot be carried out normally due to excessive pressure of the heavy object, and ensuring the normal conveying process of the materials inside the tunnel kiln.

[0022] Furthermore, a plug-in groove 2 is fixedly connected to the outer side of the outer rod 1. The outer side of the plug-in groove 2 is inserted into the inside of a rotating part 9. Symmetrically distributed clamping grooves 10 are arranged on both outer sides of the rotating part 9. A plug-in hole 11 is arranged in the middle of the outer side of the rotating part 9. The outer side of the rotating part 9 is rotatably connected to a rotating bearing inside the tunnel kiln. The two rotating parts 9 are inserted on the outer sides of the corresponding plug-in grooves 2. When the rotating bearing inside the tunnel kiln controls the rotation of the rotating part 9, the rotating part 9 can drive the internal outer rod 1 to rotate. The connection between the plug-in groove 2 and the rotating part 9 is connected by a strong adhesive.

[0023] Furthermore, the inner surface of the outer rod 1 is a heat-resistant layer 101. An anti-corrosion layer 102 is adhered inside the heat-resistant layer 101, and a reinforcement layer 103 is adhered inside the anti-corrosion layer 102. The inner coatings of the outer rod 1 are adhered by a high-temperature adhesive. The temperature resistance of the high-temperature adhesive ranges from 200 degrees to 1800 degrees, meeting the heat absorption degree during operation inside the tunnel kiln, and avoiding the situation where the adhesion effect between the inner coatings of the outer rod 1 is reduced due to high temperature. The heat-resistant layer 101 can play a certain role in temperature insulation. The anti-corrosion layer 102 is used to prevent the stick itself from being corroded during long-term operation, extending the service life of the stick body. The reinforcement layer 103 is used to reinforce the firmness of the outer rod 1, avoiding the situation where the surface of the outer rod 1 is indented due to the force during the transportation of heavy objects, resulting in the inability to carry out the delivery process normally.

[0024] Furthermore, the spring 7 is made of high-temperature resistant material to avoid the situation where the spring 7 melts due to heat, which has a certain impact on the buffering effect of the force on the outer rod 1. The spring 7 is used to buffer the pressure of the externally transported materials on the outer rod 1, effectively alleviating the impact force received when the stick body contacts the material contact surface during rotation, and extending the service life of the stick body.

[0025] The working principle of the present utility model: During use, the staff inserts the two ends of the roller stick body composed of the inner rod 3, the outer rod 1 and the connecting piece 4 into the rotating piece 9, and then inserts the outside of the rotating piece 9 into the rotating bearing inside the tunnel kiln to ensure the normal rotation of the roller stick body. When there are goods transported on the roller stick, the pressure on the contact surface of the roller stick by the material is dispersed to the other side of the outer rod 1 and the inner rod 3 through the internal spring 7, playing the role of pressure sharing and pressure buffering, and avoiding the situation where the outer rod 1 is indented at local positions due to long-term operation, which affects the subsequent transportation of goods. On the other hand, the reinforcement layer 103 inside the outer rod 1 is used to reinforce the strength of the outer rod 1 itself, the anti-corrosion layer 102 is used to isolate the corrosion degree of the transported materials on the outer rod 1, and the outermost heat-resistant layer 101 plays a role in heat insulation. The heat inside the outer rod 1 can be dissipated through the ventilation holes 5 inside the two connecting pieces 4 on both sides, avoiding the situation where excessive heat accumulates inside the outer rod 1, resulting in cracks in the stick body, extending the service life and improving the safety during operation at the same time.
