Description

Technical Field

[0001] This utility model relates to the field of refractory brick processing technology, and in particular to a refractory brick drying rack. Background Technology

[0002] After refractory bricks are pressed, they are usually air-dried to reduce their internal moisture content and prevent deformation during sintering. Currently, the method used is to stack the pressed refractory bricks together for air drying, which has low drying efficiency. Some manufacturers use racks to separate the pressed bricks to improve drying efficiency. However, the current drying racks are fixed facilities and occupy a lot of space when not in use, thus affecting production activities. Utility Model Content

[0003] This utility model provides a refractory brick drying rack to overcome the shortcomings of the prior art, making it easy to store and thus bringing convenience to production, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A refractory brick drying rack includes a pair of parallel supports, with connecting mechanisms at the upper and lower ends of the supports. Multiple placement sections are provided between the supports, and the placement sections are stacked. This connection method facilitates the separate placement of refractory bricks to improve the drying efficiency of the refractory bricks. Furthermore, the placement sections are detachably connected to the supports, making it easy to set the number of placement sections as needed. The supports connected together by the connecting mechanisms are easy to fold and store.

[0006] Furthermore, the support includes a pair of vertical tubes, with a lower plate welded to the lower end of the vertical tubes and an upper plate welded to the upper end of the vertical tubes. The vertical tubes are provided with multiple insertion holes arranged in an equally spaced array along their axial direction. A pair of protrusions are welded to both ends of the upper plate. The insertion holes are designed to facilitate locking the height of each placement part.

[0007] Furthermore, the connecting mechanism includes a hinge shaft welded to the protrusion, with a connecting arm rotatably mounted on the hinge shaft. A pair of connecting rods are positioned between the inner ends of the connecting arms at one end, with a spring sleeved on each connecting rod. An outer pressure arm is also sleeved on the connecting rod, with a insertion rod at the other end of each outer pressure arm. The insertion rod passes through the inner ends of another pair of connecting arms, and the outer pressure arms are located at both ends of the springs. The connecting arms and outer pressure arms facilitate the connection of the upper end of the support and the locking of the distance between them. To improve stability after distance adjustment, a pair of insertion rods can be provided on each outer pressure arm to prevent rotation after the connecting arms are fixed. This design also facilitates the folding and storage of the connecting arms.

[0008] Furthermore, in order to facilitate the movement of the outer pressure arm, a gripping protrusion is provided on the outer pressure arm.

[0009] Furthermore, in order to facilitate the connection and locking of the lower end of the support and to facilitate storage, a pair of rotating bosses are welded to the lower end of the lower plate. A connecting shaft is rotatably mounted on the rotating bosses, and a rotating connecting plate is rotatably mounted on the connecting shaft. A rotating groove is opened on the inner end of one pair of rotating connecting plates. The inner end of the rotating connecting plate on the other side is rotatably mounted in the rotating groove through a central connecting shaft. A limiting connecting rod is inserted into the inner end of the rotating connecting plate on the other side. The limiting connecting rod is threadedly connected to the other pair of rotating connecting plates.

[0010] Furthermore, to facilitate the connection operation of the placement section, the placement section includes an end block sleeved on one of the pair of vertical tubes. A limiting rod is welded to the inner wall of the end block and inserted into the insertion hole. A middle horizontal plate is welded to the inner wall of the end block, and multiple outward support plates are welded to both sides of the middle horizontal plate. The outward support plates on the same side are spaced apart. The pressed blank is placed on the outward support plates. This method facilitates airflow and improves the drying efficiency of the pressed blank. A moving block is sleeved on the other end of the middle horizontal plate and sleeved on another pair of vertical tubes. A positioning rod is welded to the inner wall of the moving block and inserted into the insertion hole. A concave top piece is rotatably provided on the outer end of the middle horizontal plate via an end shaft. A holding rod is welded to the outer end of the concave top piece. The inner end of the concave top piece has an arc-shaped structure and abuts against the outer end of the moving block.

[0011] The advantages of the above technical solution are:

[0012] This invention facilitates storage and, in addition, improves the drying efficiency of the pressed blanks by using a partitioned placement method. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0017] Figure 4 A magnified view of point C is shown. Detailed Implementation

[0018] like Figures 1-4As shown, a refractory brick drying rack includes a pair of parallel supports 1, with connecting mechanisms 2 at the upper and lower ends of the supports 1, and a placement part 3 between the supports 1.

[0019] The support 1 includes a pair of vertical tubes 10, with a lower plate 12 welded to the lower end of the vertical tubes 10 and an upper plate 13 welded to the upper end of the vertical tubes 10. The vertical tubes 10 are provided with a plurality of insertion holes 11 arranged in an equally spaced array along their axial direction, and a pair of protrusions 14 are welded to both ends of the upper plate 13.

[0020] The connecting mechanism 2 includes a hinge shaft welded to the protrusion 14. A connecting arm 20 is rotatably mounted on the hinge shaft. A pair of connecting rods 21 are provided between the inner ends of the connecting arm 20 at one end. A spring 24 is sleeved on the connecting rod 21. An outer pressure arm 22 is sleeved on the connecting rod 21. A holding protrusion 25 is provided on the outer pressure arm 22. An insertion rod 23 is provided at the other end of the outer pressure arm 22. The insertion rod 23 passes through the inner end of the other pair of connecting arms 20. The outer pressure arm 22 is located at both ends of the spring 24.

[0021] A pair of rotating bosses 40 are welded to the lower end of the lower plate 12. A connecting shaft 41 is rotatably mounted on the rotating bosses 40. A rotating connecting plate 42 is rotatably mounted on the connecting shaft 41. A rotating groove 46 is opened on the inner side of one pair of rotating connecting plates 42. The inner side of the rotating connecting plate 42 on the other side is rotatably mounted in the rotating groove 46 through a central connecting shaft 44. A limiting connecting rod 47 is inserted into the inner side of the rotating connecting plate 42 on the other side. The limiting connecting rod 47 is threadedly connected to the other pair of rotating connecting plates 42.

[0022] The placement part 3 includes an end block 30 sleeved on one of the pairs of vertical tubes 10. A limiting rod is welded to the inner wall of the end block 30 and inserted into the insertion hole 11. A middle horizontal plate 31 is welded to the inner wall of the end block 30. Multiple outward support plates 32 are welded to both sides of the middle horizontal plate 31 and are spaced apart from each other on the same side. A movable block 33 is sleeved on the other end of the middle horizontal plate 31 and is sleeved on another pair of vertical tubes 10. A positioning rod is welded to the inner wall of the movable block 33 and inserted into the insertion hole 11. A concave top piece 35 is rotatably provided on the outer end of the middle horizontal plate 31 through an end shaft 34. A holding rod 36 is welded to the outer end of the concave top piece 35. The inner end of the concave top piece 35 has an arc-shaped structure and abuts against the outer end of the movable block 33.

[0023] In this embodiment, when the pressed blanks are air-dried, the operator places the pressed blanks in a single layer on the extended support plate 32 of each layer placement part 3. When placing them, there should be a certain gap between each pressed blank to facilitate air circulation and thus improve the air-drying efficiency of the pressed blanks.

[0024] In this embodiment, during the deployment and erection process, the operator spreads the two sets of vertical tubes 10, which are lying flat, to a predetermined distance. After adjustment, the rotating connecting plates 42 are parallel to each other. Then, the rotating connecting plates 42 are locked by the limiting connecting rod 47 to prevent changes in the distance between the lower ends of the two sets of vertical tubes 10. Then, the connecting arm 20 is rotated, and then the outer pressure arm 22 is pressed inward so that the outer pressure arm 22 is positioned between the other pair of connecting arms 20. Then, the outer pressure arm 22 will move outward under the action of the spring 24, and one or more insertion rods 23 on it will pass through the other pair of connecting arms 20, thus completing the erection operation.

[0025] When storing, the operator can disconnect the rotating connecting plate 42 and the connecting arm 20 in sequence to store and fold it.

[0026] When connecting and fixing the placement part 3, the operator inserts the placement part 3 through the gap between the two sets of vertical tubes 10, so that the end block 30 is located outside one set of vertical tubes 10 and the moving block 33 is located outside the other set of vertical tubes 10. Then, the concave top part 35 is rotated so that the moving block 33 moves inward and finally the positioning rod and the limiting rod are inserted into the insertion hole 11.

Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
