Description

Technical Field

[0001] The utility model relates to the technical field of metal smelting reverberatory furnaces, in particular to a reverberatory furnace for metal smelting. Background Art

[0002] The reverberatory furnace, also known as the flame reverberatory furnace, is a metallurgical furnace that directly heats materials through flames to melt metals. It consists of three main parts: a combustion chamber, a smelting chamber, and an exhaust flue. The reverberatory furnace has a simple structure, small investment, and uses a wide variety of fuels. It is an important smelting equipment for non-ferrous metals such as copper, nickel, and tin.

[0003] The existing technology has the following problems:

[0004] 1. When the existing reverberatory furnace is in use, since its feed port is generally vertical or inclined, it is easy to cause a large amount of raw materials to accumulate at the bottom of the reverberatory furnace cavity, which leads to uneven heating of the raw materials during the smelting process, greatly reducing the smelting efficiency of the reverberatory furnace;

[0005] 2. When smelting metal, the existing reverberatory furnace will produce a large amount of toxic waste gas containing small particles. If these waste gases are directly discharged into the outside, they will pollute the surrounding air and fail to meet the requirements of environmentally friendly production. Utility Model Content

[0006] The utility model provides a reverberatory furnace for metal smelting to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] A reverberatory furnace for metal smelting, comprising a base, a furnace body is fixedly mounted on the upper surface of the base, a charging funnel is fixedly mounted on the top of the furnace body, a first material distribution block is fixedly mounted on the inner top of the furnace body, a second material distribution block is fixedly mounted on the inner top of the furnace body, and a material spreading mechanism is fixedly mounted on the inner wall of the charging funnel;

[0009] The material spreading mechanism includes a first rotating blade and a second rotating blade, one end of the first rotating blade is transmission-connected with a first belt, one end of the second rotating blade is fixedly mounted with a rotating gear, the teeth of the rotating gear are meshed with a transmission gear, the rotating shaft of the transmission gear is transmission-connected with a second belt, and one end of the first belt and the second belt is transmission-connected with a driving motor.

[0010] A further improvement of the technical solution of the utility model is that a molten metal outlet is fixedly installed on one side of the furnace body, and a smoke exhaust pipe is fixedly installed on the other side of the furnace body.

[0011] The above technical solution is adopted, in which a molten metal outlet and a smoke exhaust pipe are respectively installed on both sides of the furnace body, so that the molten metal after smelting can be discharged for processing. The exhaust gas is discharged through the smoke exhaust pipe, which is conducive to maintaining a stable pressure in the furnace and preventing the furnace from exploding.

[0012] A further improvement of the technical solution of the utility model is that a filter barrel is fixedly installed at the bottom of the smoke exhaust pipe, a filter net is inserted into the inner wall of the filter barrel, an activated carbon adsorption net is inserted into the inner wall of the filter barrel, and a smoke outlet pipe is fixedly installed on the top of the filter barrel.

[0013] By adopting the above technical solution, a filter barrel is installed at the end of the smoke exhaust pipe, which can filter out harmful particulate matter and adsorb toxic substances from the exhaust smoke, thereby greatly reducing the pollution of the exhaust gas and reducing the harm to the environment.

[0014] A further improvement of the technical solution of the utility model is that a rotating hinge is installed on one side of the filter barrel, a barrel door is fixedly installed on one side of the rotating hinge, and the barrel door is tightly closed with the filter barrel.

[0015] By adopting the above technical solution, since the effect of the filter net and the activated carbon adsorption net will be greatly reduced after working for a long time, the interior can be cleaned and replaced through the openable barrel door to ensure the normal filtering effect of the filter barrel, and at the same time, it is tightly connected to the filter barrel to avoid the problem of pollution caused by exhaust gas leakage from the gap.

[0016] A further improvement of the technical solution of the utility model is that the tops of the first dividing block and the second dividing block are of beveled edge structure on both sides, and a fireproof partition is installed at the bottom.

[0017] By adopting the above technical solution, the first material distribution block and the second material distribution block in the solution have inclined plates on both sides, so that the entry channel is divided into three channels. When the raw materials enter, they will be evenly scattered to the bottom from three places, so that they cannot accumulate at one point. The combustion and smelting speed will be faster and the heat utilization rate will be higher.

[0018] A further improvement of the technical solution of the utility model is that the first rotating blade and the second rotating blade are not close to each other, and the distance between the first rotating blade and the second rotating blade is the same as the distance between the inner sides of the first dividing block and the second dividing block.

[0019] By adopting the above technical solution, when the raw materials are poured into the feeding funnel, part of the raw materials are brought to both sides by the first rotating blade and the second rotating blade, and part of the raw materials enter the furnace from the channel reserved in the middle, so that the raw materials can evenly enter the three channels for smelting, thereby improving the smelting efficiency.

[0020] A further improvement of the technical solution of the utility model is that the spreading mechanism is integrated into a structure by a first rotating blade, a second rotating blade, a first belt, a rotating gear, a transmission gear, a second belt, and a driving motor, and the second rotating blade rotates in an opposite direction to the first rotating blade under the action of the rotating gear, the transmission gear, and the second belt.

[0021] By adopting the above technical solution, the raw materials can be evenly discharged into the interior of the furnace body through three channels through the spreading mechanism, so that they cannot accumulate at one point, which greatly improves the smelting efficiency. At the same time, the first rotating blade and the second rotating blade rotating in opposite directions can discharge the raw materials from the channels on both sides.

[0022] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0023] 1. The utility model provides a reverberatory furnace for metal smelting. A driving motor drives a first belt, a rotating gear, a transmission gear and a second belt to operate, so that the first rotating blade and the second rotating blade rotate in opposite directions, and raw materials can be evenly discharged from three channels at the bottom into the furnace body for smelting, so that the raw materials cannot be accumulated at one point in the furnace, thereby making the original heating more uniform, greatly improving the efficiency during smelting.

[0024] 2. The utility model provides a reverberatory furnace for metal smelting. The exhaust gas can be discharged into a filter barrel for filtration through a smoke exhaust pipe. Under the action of the filter net and the activated carbon adsorption net, smaller particles can be filtered and toxic gases can be adsorbed, thereby reducing the harm of the exhaust gas to the environment and improving the environmental protection of the smelting.

[0033] The spreading mechanism 6 includes a first rotating blade 601 and a second rotating blade 602, one end of the first rotating blade 601 is transmission-connected to a first belt 603, one end of the second rotating blade 602 is fixedly mounted with a rotating gear 604, the teeth of the rotating gear 604 are meshed with a transmission gear 605, the rotating shaft of the transmission gear 605 is transmission-connected to a second belt 606, and one end of the first belt 603 and the second belt 606 is transmission-connected to a driving motor 607.

[0034] In this embodiment, the driving motor 607 drives the first belt 603, the rotating gear 604, the transmission gear 605, and the second belt 606 to operate, so that the first rotating blade 601 and the second rotating blade 602 rotate in opposite directions, and the raw materials can be evenly discharged into the furnace body 2 from the three channels at the bottom for smelting, so that the raw materials cannot be accumulated at one point in the furnace, thereby making the original heating more uniform, greatly improving the efficiency during smelting.
