Description

Technical Field

[0001] This utility model relates to the field of sampling technology for melting furnaces, specifically a sampling device for metal melting furnaces. Background Technology

[0002] In the non-ferrous metal manufacturing industry, it is often necessary to use a melting furnace to heat solid metal raw materials to a molten state. During the heating process, it is necessary to take samples of the liquid metal in the melting furnace multiple times and analyze the composition of the samples using instruments to determine the quality of the metal in the melting furnace.

[0003] Current metal melting furnace sampling devices are too simple in structure. During sampling, personnel are easily exposed to the high temperatures overflowing from the furnace. After sampling, the sampling dish has poor sealing, and the sample does not cool down quickly enough, causing the hot molten metal inside the dish to spill out, resulting in low safety. Therefore, we propose a metal melting furnace sampling device. Utility Model Content

[0026] 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.

[0027] Please see Figures 1-6 The present invention provides a technical solution as follows:

[0028] A sampling device for a metal melting furnace includes a housing 1, which is cylindrical and has one end inserted into the sampling port of the metal melting furnace. The housing 1 has a cylindrical chamber inside with an opening at the bottom, allowing one end of the chamber to communicate with the outside. A pull rope 2, made of high-temperature resistant steel wire rope, is installed inside the housing 1. One end of the pull rope 2 is fixedly connected to a sampling dish 3, and the other end is connected to a winding assembly 4. The winding assembly 4 winds up the pull rope 2, thereby drawing the sampling dish 3 from the opening into the chamber. The sampling dish 3 has a cavity inside to hold the sample, and a feed inlet at its top, allowing the sample to enter the cavity. The housing 1 includes a cooling assembly 5 for cooling the sampling dish 3 and a sealing assembly 6 for sealing the feed inlet of the sampling dish 3 to prevent leakage of the high-temperature sample.

[0029] Specifically, the winding assembly 4 in this embodiment includes a motor 401 mounted on the housing 1. The output end of the motor 401 is fixedly connected to a winding roller 402. One end of the pull rope 2 is fixed and wound around the winding roller 402. The motor 401 is a stepper motor with a certain degree of self-locking. In use, the winding roller 402 is driven to rotate in a specified direction by the shaft of the motor 401 to wind up the pull rope 2.

[0030] To prevent leakage of the high-temperature molten sample inside the sampling dish 3, the sealing assembly 6 includes a fixed plate 601 fixedly connected to the inner wall of the housing 1. A limiting slide rod 602 is slidably connected to the inner wall of the fixed plate 601. A sealing plate 603 is fixedly connected to one end of the limiting slide rod 602. The sealing plate 603 is used to seal the inlet on the sampling dish 3. There are at least two limiting slide rods 602 to improve the stability of the movement of the sealing plate 603, thereby enabling the sealing plate 603 to be better aligned with the sampling dish 3. One end of the pull rope 2 passes through the sealing plate 603 and is connected to the sampling dish 3. The surface of the pull rope 2 is slidably connected to the inner wall of the sealing plate 603. The pull rope 2 can slide inside the sealing plate 603 when wound up, pulling the sampling dish 3 upward. When the sampling dish 3 is aligned with the sealing plate 603, it can drive the sealing plate 603 to move, so that the sealing plate 603 and the sampling dish 3 enter the cavity inside the housing 1 together. An elastic plate 604 is fixedly connected to the end of the limiting slide bar 602 away from the sealing plate 603. The end of the elastic plate 604 away from the limiting slide bar 602 is connected to the inner wall of the housing 1 through a spring 605. By setting the spring 605 and the elastic plate 604, the limiting slide bar 602 and the sealing plate 603 can automatically reset during the unwinding process.

[0031] In this embodiment, the cooling component 5 includes a baffle 501 fixedly connected to the inner wall of the housing 1. The baffle 501 is located between the fixed plate 601 and the sealing plate 603. A cooling fan 502 is installed on the inner wall of the baffle 501, which can cool the sampling dish 3 and the high-temperature sample inside through air cooling. The cooling fan 502 is located in the middle of the baffle 501, making the contact between the cold air and the sampling dish 3 more uniform. Please refer to [link / reference]. Figure 4 A guide wheel 7 is rotatably installed inside the housing 1 to guide the pull rope 2, thereby keeping the pull rope 2 away from the area where the cooling fan 502 is located.

[0032] Further, please refer to Figure 5 The outer diameter of the sampling dish 3 is smaller than the inner diameter of the shell 1. When the sampling dish 3 enters the shell 1, there is a gap between it and the inner wall of the shell 1, so that the hot air inside the shell 1 can be discharged, thereby improving the heat dissipation effect.

[0033] A cooling cavity 101 is provided on the inner wall of the shell 1. The cooling cavity 101 contains a cooling medium to improve the cooling efficiency of the internal materials of the shell 1.

[0034] In addition, the cooling component 5 also includes a protrusion 503 formed on the housing 1. The protrusion 503 is located on the side of the baffle 501 away from the sampling dish 3, that is, the air inlet end of the cooling fan 502. Multiple air inlet pipes 504 are distributed in a circular array on the inner wall of the protrusion 503. One end of the air inlet pipe 504 is connected to the outside of the housing 1, and the other end is connected to the inside of the housing 1. When the cooling fan 502 is running, outside air enters the inside of the housing 1 through the air inlet pipe 504. During the entry process, the protrusion 503 can extend the air inlet channel and insulate the heat around the housing 1. In addition, the protrusion 503 can also act as a limiter, allowing the sampling device to be placed on the sampling port of the metal melting furnace.

[0035] In use, the metal melting furnace sampling device of this utility model is first inserted into the metal melting furnace through the sampling port at one end. Then, the motor 401 is started to unwind the winding roller 402. During the unwinding process, the elastic plate 604 moves under the elastic force of the spring 605, which in turn pushes the sealing plate 603 away from the spring 605 through the limiting slide rod 602. The sealing plate 603 simultaneously drives the sampling dish 3 to move until the sampling dish 3 is completely pushed out of the housing 1. At this time, the sampling dish 3 falls automatically under its own gravity and detaches from the sealing plate 603. The elastic plate 604 is restricted by the fixing plate 601 and cannot move further, so that the sealing plate 603 remains in the designated position and does not fall with the sampling dish 3.

[0036] The sampling dish 3 falls into the material to take a sample. After obtaining the sample, the cooling fan 502 is started, and the motor 401 drives the winding roller 402 to wind up the pull rope 2, pulling the sampling dish 3 upward. When the sampling dish 3 moves to the designated position, it will dock with the sealing plate 603, so that the sealing plate 603 seals the feed port on the sampling dish 3. Then the sampling dish 3 and the sealing plate 603 enter the housing 1 together.

[0037] After the cooling fan 502 is started, external air enters the housing 1 through the air intake pipe 504, comes into contact with the sampling dish 3 and is blown out, carrying away the heat in the sampling dish 3 and increasing the cooling rate of the sampling dish 3 and the sample inside.
