A furnace for hot-dip galvanizing

Abstract

This utility model relates to the technical field of hot-dip galvanizing heating furnaces, and discloses a furnace for hot-dip galvanizing processing, including a furnace body, with a guide hopper fixedly connected inside the furnace body. This utility model's technical solution uses the guide hopper to collect impurities that fall off the workpiece, preventing impurities from directly accumulating at the bottom of the furnace body. Impurities entering the guide hopper continue into the discharge pipe. Simply pulling up a baffle opens the discharge pipe, allowing impurities to be discharged without opening the furnace body. After discharge, the baffle returns to its original position, and then the locking screws on the fixing plate are rotated to abut against both sides of the baffle, thus fixing the baffle. Simultaneously, the baffle also prevents heat loss from the furnace body through the discharge pipe, making it convenient and practical. It also avoids the corrosive components in the residue accumulated at the bottom of the furnace body, which can easily accelerate the oxidation and loss of the metal material at the bottom of the furnace, thus preventing a shortened service life of the furnace body.

Description

Technical Field

[0001] This utility model relates to the technical field of hot-dip galvanizing furnaces, specifically a furnace for hot-dip galvanizing. Background Technology

[0002] Hot-dip galvanizing furnaces are key equipment used to heat workpieces during the hot-dip galvanizing production process. Their core function is to heat the workpieces to be galvanized to a specific temperature to meet the requirements of the galvanizing process (such as removing the oxide layer on the workpiece surface and achieving a good bond between the zinc liquid and the workpiece).

[0003] When workpieces are heated in the furnace, the surface oxide layer, residual zinc liquid volatiles, and impurities not completely removed during the pretreatment stage will gradually fall off and be deposited at the bottom of the furnace under gravity. The corrosive components in the residue can easily accelerate the oxidation and loss of the metal material at the bottom of the furnace and shorten the service life of the furnace. Therefore, a furnace for hot-dip galvanizing is needed. Utility Model Content

[0004] The purpose of this invention is to provide a furnace for hot-dip galvanizing, which solves the problems mentioned in the background art.

[0005] This application provides a hot-dip galvanizing furnace, including a furnace body. A guide hopper is fixedly connected inside the furnace body. A discharge pipe is fixedly connected to the bottom end of the guide hopper. The discharge pipe is connected to the guide hopper. The end of the discharge pipe away from the guide hopper extends to the outside of the furnace body. A partition is slidably provided at the top end of the discharge pipe. Fixing plates are fixedly connected to both outer walls of the discharge pipe. Locking screws are threaded through the fixing plates and abut against the outer wall of the partition.

[0006] In use, first open the sealed door, place the small workpiece to be heated on the support frame, then close the sealed door and start the heater. The heater heats the inside of the furnace, thus heating the workpiece. While the workpiece is being heated in the furnace, the surface oxide layer, residual zinc liquid volatiles, and impurities not completely removed during the pretreatment stage will gradually fall off and into the guide hopper. The impurities in the guide hopper continue into the discharge pipe. When impurities need to be discharged, the operator only needs to pull the baffle upward to open the discharge pipe opening, allowing the impurities to be discharged without opening the furnace. After discharge, the baffle is reset downward, and then the locking screw on the fixing plate is rotated to abut against both sides of the baffle, thus fixing the baffle. At the same time, the baffle also prevents heat loss from the furnace through the discharge pipe, which is convenient and practical. It avoids the corrosive components in the residue accumulated at the bottom of the furnace, which can easily accelerate the oxidation and loss of the metal materials at the bottom of the furnace, thus preventing a shortening of the furnace's service life.

[0007] Optionally, heaters and support plates are fixedly connected to the inner walls of both sides of the furnace body. The support plates are located below the heaters, and a support frame is fixedly connected to the top of the support plates by bolts. The support frame is located above the guide hopper.

[0008] By adopting the above technical solution, the heater can heat the inside of the furnace body, thereby achieving heat treatment of the workpiece, and the support frame can place the workpiece flat and play the role of supporting the workpiece.

[0009] Optionally, a sealing door is rotatably connected to the front wall of the furnace body.

[0010] By adopting the above technical solution, the furnace body can be opened or closed through the sealed door, which is beneficial for the loading and unloading of workpieces.

[0011] Optionally, a handle is fixedly connected to the top of the partition.

[0012] By adopting the above technical solution, the handle allows workers to pull the partition upwards more flexibly.

[0013] Optionally, the discharge pipe is a square bend.

[0014] By adopting the above technical solution, the residue passing through the curved channel inside the discharge pipe can be directly discharged by the downward impact force, avoiding blockage inside the discharge pipe.

[0015] Optionally, the guide hopper and discharge pipe are both made of 310S high-temperature resistant stainless steel.

[0016] By adopting the above technical solutions, it is beneficial to improve the high temperature resistance of the guide hopper and discharge pipe, and extend their service life.

[0017] Optionally, the top end of the discharge pipe is provided with a slot that is compatible with the partition plate.

[0018] By adopting the above technical solution, it is beneficial for the partition to slide up and down, thereby opening or closing the outlet of the discharge pipe.

[0019] Optionally, the partition and the fixing plate are on the same horizontal straight line.

[0020] By adopting the above technical solution, the locking screw on the fixing plate can accurately abut against the partition, thereby improving the fixing effect of the partition.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] This technical solution uses a guide hopper to collect impurities that fall off the workpiece, preventing them from accumulating directly at the bottom of the furnace. Impurities entering the guide hopper continue into the discharge pipe. Simply pulling the baffle upwards opens the discharge pipe, allowing impurities to be discharged without opening the furnace. After discharge, the baffle returns to its original position, and the locking screws on the fixing plate are rotated to abut against both sides of the baffle, thus securing it. The baffle also prevents heat loss from the furnace through the discharge pipe, making it convenient and practical. It avoids the corrosive components in the residue accumulating at the bottom of the furnace, which can accelerate the oxidation and loss of the furnace bottom metal, thus shortening the furnace's service life.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a hot-dip galvanizing furnace, including a furnace body 2, a guide hopper 5 fixedly connected inside the furnace body 2, a discharge pipe 6 fixedly connected to the bottom end of the guide hopper 5, the discharge pipe 6 communicating with the guide hopper 5, the end of the discharge pipe 6 away from the guide hopper 5 extending to the outside of the furnace body 2, a partition 9 slidably provided at the top end of the discharge pipe 6, and fixing plates 10 fixedly connected to both outer walls of the discharge pipe 6, with locking screws 11 threaded through the fixing plates 10, the locking screws 11 abutting against the outer wall of the partition 9.

[0030] In the technical solution of this utility model, heaters 1 and support plates 4 are fixedly connected to the inner walls of both sides of the furnace body 2. The support plate 4 is located below the heater 1, and a support frame 3 is fixedly connected to the top of the support plate 4 by bolts. The support frame 3 is located above the guide hopper 5. The heater 1 can realize the internal heating of the furnace body 2, thereby realizing the heat treatment of the workpiece. The support frame 3 can place the workpiece flat and play the role of supporting the workpiece.

[0031] In the technical solution of this utility model, a sealing door 7 is rotatably connected to the front wall of the furnace body 2; the sealing door 7 enables the furnace body 2 to be opened or closed, which is beneficial for the loading and unloading of workpieces.

[0032] In the technical solution of this utility model, a handle 8 is fixedly connected to the top of the partition 9; the handle 8 enables the staff to pull the partition 9 upward more flexibly.

[0033] In the technical solution of this utility model, the discharge pipe 6 is a square bend pipe; it enables the residue passing through the internal bend channel of the discharge pipe 6 to be discharged directly by means of the downward impact force, thus avoiding blockage inside the discharge pipe 6.

[0034] In the technical solution of this utility model, both the guide hopper 5 and the discharge pipe 6 are made of 310S high temperature resistant stainless steel; this is beneficial to improving the high temperature resistance of the guide hopper 5 and the discharge pipe 6 and extending their service life.

[0035] In the technical solution of this utility model, the top end of the discharge pipe 6 is provided with a slot that matches the partition 9; this facilitates the up-and-down sliding of the partition 9, thereby opening or closing the pipe opening of the discharge pipe 6 through the up-and-down sliding.

[0036] In the technical solution of this utility model, the partition 9 and the fixing plate 10 are on the same horizontal straight line; this enables the locking screw 11 on the fixing plate 10 to accurately abut against the partition 9, thereby improving the fixing effect of the partition 9.

[0037] In use, first open the sealing door 7, place the small workpiece to be heated on the support frame 3, then close the sealing door 7 and start the heater 1. The heater 1 can heat the inside of the furnace body 2, thereby achieving the heat treatment of the workpiece. When the workpiece is heated in the furnace body 2, the surface oxide layer, residual zinc liquid volatiles, and impurities not completely removed in the pretreatment stage will gradually fall off and fall into the guide hopper 5. The impurities entering the guide hopper 5 continue to enter the discharge pipe 6. When it is necessary to discharge impurities, the operator only needs to pull the partition 9 upward to open the pipe opening of the discharge pipe 6. The impurities can be discharged outward without opening the furnace body 2. After the discharge is completed, the partition 9 is reset downward. Then, the locking screw 11 on the fixing plate 10 is rotated to abut against both sides of the partition 9 to complete the fixation of the partition 9. At the same time, the partition 9 can also prevent the heat in the furnace body 2 from being lost through the discharge pipe 6. It is convenient and practical, and avoids the corrosive components in the residue accumulated at the bottom of the furnace body 2 from easily accelerating the oxidation and loss of the metal material at the bottom of the furnace, so as not to shorten the service life of the furnace body 2.
