Abstract
Description
Technical Field
[0001] This application relates to the technical field of heat exchange racks for heat treatment furnaces, and in particular to a heat exchange rack for a heat treatment furnace. Background Technology
[0002] A heat treatment furnace is an electric or fuel-fired furnace used for heating furnace materials for heat treatment. Commonly used heat treatment furnaces include box-type resistance furnaces, pit-type resistance furnaces, gas carburizing furnaces, and salt bath furnaces. Continuous furnaces are usually used, where materials are continuously fed in through the feeding door, pass through the furnace chamber, and are continuously discharged through the discharge door.
[0003] Currently, in the pit-type heat treatment furnaces used in factories, materials are first placed into a rack, and then the rack is placed into the pit-type heat treatment furnace for heat treatment. The purpose of the rack is to avoid direct contact between the materials and the pit-type heat treatment furnace, so that the materials are heated more evenly. Existing pit-type heat treatment furnaces typically use a heat exchange rack that is a support cylinder. During heating, the heat treatment furnace directly contacts the support cylinder, thereby transferring heat to the materials inside. Those skilled in the art have provided a heat exchange rack for a heat treatment furnace to solve the problems mentioned in the background art. Utility Model Content
[0004] To address the problems mentioned in the background art, this application provides a heat exchange rack for a heat treatment furnace.
[0005] The heat exchange rack for a heat treatment furnace provided in this application adopts the following technical solution:
[0006] A heat exchange material rack for a heat treatment furnace includes a base. A fixing column is fixedly installed at the upper end of the base near the middle position. Two threaded sections are opened on the outside of the fixing column. A first placement frame and a second placement frame are sleeved on the outside of the fixing column. A lifting ring is fixedly installed at the upper end of the first placement frame and the second placement frame. Through holes are opened on the outside of the first placement frame and the second placement frame. The outer surfaces of the first placement frame and the second placement frame are coated with a high-temperature resistant material.
[0007] Preferably, the fixed column is fitted with two sets of threaded sleeves, namely threaded sleeve one and threaded sleeve two, and the two sets of threaded sleeves one and threaded sleeve two are threadedly connected to the fixed column.
[0008] Preferably, each set of threaded sleeve one and threaded sleeve two consists of two, and threaded sleeve one and threaded sleeve two are located at the upper and lower ends of placement frame one and placement frame two, respectively.
[0009] Preferably, the base has a notch or groove on its exterior, and a rotating rod is movably mounted inside the notch or groove.
[0010] Preferably, a guide plate is fixedly installed on the outside of the rotating rod, and a groove is formed at one end of the guide plate, with a roller movably installed inside the groove.
[0011] Preferably, a rotating motor is fixedly installed inside the base, and the rotating motor provides power to the rotating rod.
[0012] In summary, this application includes the following beneficial technical effects: the placement frame one and placement frame two can accommodate the exchange of two sets of materials, resulting in high efficiency. The lifting rings facilitate the lifting machine to place and retrieve placement frame one and placement frame two. Furthermore, rotating threaded sleeve one and threaded sleeve two can change the vertical spacing between placement frame one and placement frame two, making it easier to accommodate materials of different heights.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] like Figures 1-3 As shown, a heat exchange material rack for a heat treatment furnace includes a base 1. A fixing column 5 is fixedly installed at the upper end of the base 1 near the middle position. Two threaded sections 8 are opened on the outside of the fixing column 5. A first placement frame 3 and a second placement frame 6 are sleeved on the outside of the fixing column 5. A lifting ring 7 is fixedly installed at the upper end of both the first placement frame 3 and the second placement frame 6. Through holes 4 are opened on the outside of the first placement frame 3 and the second placement frame 6. The outer surfaces of the first placement frame 3 and the second placement frame 6 are coated with a high-temperature resistant material.
[0019] The placement frames 1 (3) and 2 (6) can facilitate the exchange of two sets of materials, resulting in high efficiency. The lifting ring 7 makes it easy for the hoist to place and retrieve the placement frames 1 (3) and 2 (6). The rotating threaded sleeves 1 (9) and 2 (10) can change the vertical spacing between the placement frames 1 (3) and 2 (6), making it convenient to support materials of different heights.
[0020] In this embodiment, two sets of threaded sleeves 9 and 10 are fitted on the outside of the fixed column 5, and the two sets of threaded sleeves 9 and 10 are threadedly connected to the fixed column 5.
[0021] In this embodiment, there are two threaded sleeves 1-9 and 2-10 in each group, and the threaded sleeves 1-9 and 2-10 are located at the upper and lower ends of the placement frame 1-3 and the placement frame 2-6, respectively.
[0022] In this embodiment, a notch 2 is provided on the outside of the base 1, and a rotating rod 11 is movably installed inside the notch 2.
[0023] In this embodiment, a guide plate 12 is fixedly installed on the outside of the rotating rod 11. A groove 13 is provided at one end of the guide plate 12, and a roller 14 is movably installed inside the groove 13.
