Description

Technical Field

[0001] This utility model relates to the field of lead melting furnace technology, specifically a square lead melting furnace body. Background Technology

[0002] A lead melting furnace is an industrial device used to melt lead blocks. It is commonly used in lead-acid battery recycling, lead alloy preparation, and radiation shielding material production.

[0003] Lead smelting furnaces generate a large amount of lead vapor during operation. Lead vapor is one of the most dangerous pollutants in lead smelting operations, and its harm far exceeds that of solid lead dust. It poses a significant threat to the health of workers. Existing integrated fume hoods require a crane to move the entire hood when hoisting materials and equipment. Due to the large weight of the hood, there are significant safety hazards during the movement process. Furthermore, it is difficult to seal the hood to the furnace body, resulting in the leakage of flue gas. In addition, the fume hood is difficult to move when adding materials or stirring in the lead smelting furnace, thus occupying working space.

[0004] Therefore, this utility model provides a square lead melting furnace body to solve the above problems. 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] This utility model provides a square lead melting furnace body, including an outer shell 1, a heating component 2, a heat preservation component 5, a smoke collection hood moving component 3, and a smoke collection component 6, as shown below. Figure 1-6 As shown, the bottom of the outer shell 1 is rotatably connected with a locking universal wheel 4. The lead melting furnace can be moved or fixed by the locking universal wheel 4. The interior of the outer shell 1 is provided with a lead melting furnace body 7, and the entire lead melting process is carried out in the provided lead melting furnace body 7.

[0028] An insulation component 5 is installed on the outside of the lead melting furnace body 7. The insulation board 501 is fixedly connected to the insulation cotton 503 by bolts 504. The insulation cotton 503 is divided into four independent modules according to the shape of the outside of the lead melting furnace body. This design allows the insulation cotton 503 in a single module to be damaged without replacing all the insulation cotton 503, saving costs and facilitating disassembly by operators. The bolts 504 used for fixing are installed with a torque wrench to ensure that the tightening torque of the bolts 504 is kept uniform, which can avoid local overtightening and damage to the insulation cotton 503. A lifting block 502 is fixedly connected to the outside of the insulation board 501. The operator can fix the lifting block 502 by lifting equipment and then pull out the insulation component 5 directly, which can be replaced at any time without having to specially disassemble the equipment to replace the insulation cotton 503.

[0029] A heating component 2 is installed on the outside of the insulation component 5. The electric heating coil 201 is evenly distributed on the outside of the insulation component 5. The fixing block 202 is fixedly connected to the outer shell 1. The fixing block 202 can fix and limit the electric heating coil 201. After the electric heating coil 201 is energized, it can heat the furnace body 7 of the lead melting furnace. Heating the lead melting furnace by electric heating can accurately control the heating temperature.

[0030] The outer side of the outer casing 1 is provided with a fume hood moving assembly 3. The top of the electric push rod 301 is equipped with a lead screw frame 302. The electric push rod 301 can drive the lead screw frame 302 to move up and down and can be adjusted according to the size of the lead melting furnace. The lead screw 303 is installed inside the lead screw frame 302. One end of the lead screw 303 is fixedly connected to a micro motor 305. The micro motor 305 can drive the lead screw 303 to move. A moving block 304 is slidably connected to the surface of the lead screw 303. When the micro motor 305 is started, it drives the lead screw 303 to move and drives the moving block 304 to move left and right. Through the combined action of the lead screw 303 and the electric push rod 301, the entire lead melting process of the lead melting furnace can be tracked in real time.

[0031] A smoke collection assembly 6 is installed on the top of the moving assembly 3 of the smoke collection hood, and a flange 602 is installed on the top of the smoke collection hood 601. The smoke collection hood 601 is connected to the high-temperature resistant hose 603 through the flange 602. The use of the flange 602 allows for quick replacement of the high-temperature resistant hose 603, which is convenient for operators. A filter 604 is fixedly installed at one end of the high-temperature resistant hose 603, and an induced draft fan 605 is provided on one side of the filter 604. Through the combined action of these components, the lead vapor generated during the lead melting process in the lead melting furnace can be filtered and removed, ensuring the health of the operators.

[0032] When preparing for the lead melting process, move the outer casing 1 to a suitable position and feed the square lead melting furnace with an external conveyor belt or feeder. After feeding, start the electric heating coil 201 to heat the lead melting furnace. At the same time as starting the electric heating coil 201, start the fume hood moving component 3 and the micro motor 305. Through the combined action of the electric push rod 301 and the lead screw 303, the fume hood 601 can be moved to the top of the lead melting furnace body 7 to collect and filter the lead vapor generated during the lead melting process. During the heating of the lead melting furnace body 7, the heat preservation component 5 can keep the lead melting furnace body 7 warm. After the lead melting process is completed, move the fume hood moving component 3 to an open space, and then use a special tool to recover the lead liquid generated after lead melting.

[0033] Working principle: The electric actuator 301 enables the vertical movement of the fume hood moving component 3, and the micro motor 305 drives the lead screw 303 to move left and right. The fume hood 601 is fixedly connected to the bottom of the moving block 304. Through the movement of the electric actuator 301 and the lead screw 303, it can be moved in time when the square lead melting furnace needs to be lifted on the upper part of the furnace body during processes such as feeding, stirring, slag removal and lead pump operation, without occupying the space above.

[0034] Meanwhile, multiple sets of insulation cotton 503 are installed on the surface of the insulation board 501 by bolts 504. When a single set of insulation cotton 503 is damaged, the insulation component 5 can be lifted by lifting block 502, and the damaged insulation cotton 503 can be replaced individually.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
