Description

Technical Field

[0001] This utility model belongs to the technical field of metal smelting equipment, specifically relating to a heat preservation device for crude tin smelting. Background Technology

[0002] In the tin smelting process, molten tin needs to be stored in a heat-insulating pot between the next and next processes. As the crude molten tin flows slowly and continuously into the next process, the molten tin remains in the heat-insulating pot for a long time. Exposure of the molten tin to the air will lead to serious oxidation loss and heat dissipation.

[0003] Existing technologies often use simple coverings for insulation, but they have the following drawbacks: traditional insulation covers leak air severely, resulting in an oxidation rate of 5%-8% in the molten tin inside the pot during the insulation process; in addition, manual monitoring of the liquid level requires frequent opening of the cover, resulting in large temperature fluctuations (above ±30℃); existing simple pot covers also lack safety interlocking structures, posing a high risk of hot molten molten splatter.

[0004] Therefore, how to provide a heat preservation device for crude tin smelting is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a heat preservation device for crude tin smelting, which reduces the temperature loss and oxidation loss of molten tin in the heat preservation container, while providing liquid level monitoring and safety protection.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a heat preservation device for crude tin smelting, comprising:

[0007] A cover is used to cover a container to form an insulated space with the container. The inner edge of the cover is provided with a sealing strip that closely seals the container opening, and the top side of the cover is provided with a sliding hole.

[0008] A reference ruler is vertically fixed to the top side of the cover and arranged near the sliding hole;

[0009] A float level indicator assembly is slidably connected to the sliding hole. The float level indicator assembly floats up and down based on the liquid inside the container. The float level indicator assembly, in conjunction with the reference ruler, indicates the liquid level information inside the container.

[0010] The technical advantages of this invention are: the cover and container together form an insulated space, reducing the temperature loss of the molten tin inside the container; at the same time, the cover is equipped with a sealing strip that closely seals the container opening, reducing the oxidation reaction between external gas and the molten tin inside the container; and the float level indicator and reference ruler enable workers to monitor the liquid level inside the container in real time without opening the cover, further reducing temperature loss.

[0011] Preferably, the float level indicator assembly includes a hollow float and an indicator rod. The hollow float is fixed to one end of the indicator rod, and the indicator rod slides up and down within the sliding hole. An indicator block is fixed to the other end of the indicator rod, and the indicator block cooperates with the reference ruler to indicate the liquid level inside the container.

[0012] The resulting technical effect is that by using the mechanism of a hollow float that rises and falls with the liquid level, in conjunction with an indicator rod, the liquid level inside the container can be monitored from the outside. The indicator block can help staff obtain the liquid level inside the container from a distance without the need for close observation, thus improving the convenience of use.

[0013] Preferably, the hollow float is a stainless steel hollow sphere.

[0014] The resulting technical effect is that the density of stainless steel is less than that of tin, ensuring that the float can float normally.

[0015] Preferably, a boss is fixed to the bottom outer edge of the cover, and a plurality of connecting holes are provided on the boss, with a fixing component for disassembling and connecting the container provided in the connecting holes.

[0016] The resulting technical effect is that the boss, in conjunction with the fastener, locks the cover at the container opening, the container has the necessary fastener connection conditions, ensuring safe use and preventing accidents.

[0017] Preferably, the top side of the cover is provided with a glass observation window.

[0018] The resulting technical effect is that the observation window can help staff observe the internal conditions of the container and obtain the storage status of the molten tin.

[0019] Preferably, the top edge of the cover is provided with multiple handles, and the outside of the handles is provided with a heat insulation sleeve.

[0020] The resulting technical benefits are: the handle makes it easier for staff to pick up and put down the cover, and the heat insulation sleeve prevents staff from being accidentally burned during operation.

[0021] Preferably, the sealing strip is a silicone strip.

[0022] The resulting technical effects are: the purpose of the sealing strip is to reduce the oxidation reaction between external gas and the molten tin inside the container; at the same time, the sealing strip formed by the silicone plate has high temperature resistance, ensuring its normal use.

[0028] Cover 1 is made of stainless steel to cover the container and form an insulated space. The inner edge of cover 1 is provided with a sealing strip 2 to seal the container opening, reducing the contact reaction between external gas and the molten tin inside the container. The top side of cover 1 is provided with a sliding hole.

[0029] Reference ruler 3 has a measuring range of 0-30cm and an accuracy of ±1mm. Reference ruler 3 is vertically fixed on the top side of the cover 1 and arranged close to the sliding hole.

[0030] The float level indicator component 4 is slidably connected to the sliding hole. The float level indicator component 4 floats up and down based on the liquid (molten solder) inside the container (insulated pot). The float level indicator component 4, together with the reference ruler 3, indicates the liquid level information inside the container, which makes it convenient for staff to monitor the liquid level status inside the container in real time without having to frequently open the lid.

[0031] In other embodiments, the float level indicator assembly 4 includes a hollow float 41 and an indicator rod 42. The hollow float 41 is fixed to one end of the indicator rod 42, and the indicator rod 42 slides up and down in a sliding hole. An indicator block 43 is fixed to the other end of the indicator rod 42. The indicator block 43, in conjunction with the reference ruler 3, indicates the liquid level inside the container. The indicator block allows workers to obtain liquid level information inside the container from a distance without the need for close observation, thus improving the ease of use of the device.

[0032] In practical use, the indicator rod can be selected as an adjustable telescopic rod, with an adjustable length range of 30cm to 50cm.

[0033] In some other specific embodiments, the hollow float 41 is a stainless steel hollow sphere. The density of the stainless steel sphere is less than that of the crude molten tin, which ensures that it floats normally.

[0037] In some other embodiments, the sealing strip 2 is cut from a silicone sheet and is suitable for high-temperature environments.

[0038] This device reduces oxidation loss of molten tin between processes to below 2%, and controls molten tin temperature fluctuations within ±5℃. It enables visual monitoring of the liquid level through a float-scale linkage, preventing heat loss from opening the lid. The device features a fixed fixture and a heat-insulating handle design, ensuring safe use and preventing burns.

[0039] This heat preservation device can be directly applied in tin production and has the advantages of being simple and safe.

[0040] The diameter of the cover is 10-15mm larger than the furnace opening to facilitate the formation of an airtight edge. The float diameter is 30mm, and the connecting rod length is adjustable from 30-50cm.

[0041] During the smelting process, the buoyancy ball rises and falls with the liquid level, and the height of the indicator block changes through the indicator rod. The height of the liquid level in the pot is determined by the reference rod, which reduces heat loss caused by frequent lid opening.
