Description

Technical Field

[0001] This invention belongs to the technical field of red lead preparation equipment, specifically relating to an integrated energy-saving preparation device for red lead semi-finished products. Background Technology

[0002] The first step in the production of red lead is "lead melting," which involves placing lead ingots into a lead melting furnace to melt them into molten lead. This molten lead then proceeds to the next powdering stage. Typically, a red lead production line is equipped with three lead melting furnaces to ensure optimal production efficiency and output-capacity ratio. As is well known, traditional lead melting furnaces mostly use electric heating, and because lead ingots have a high melting point, the temperature inside the furnace generally reaches around 450℃ to achieve rapid melting, making it a highly energy-intensive piece of equipment. The second process is "lead powdering," which involves pulverizing the lead after it has been melted. This process involves transporting the molten lead to a lead powdering furnace for primary oxidation. Currently, the more advanced method involves the molten lead flowing into the lead powdering furnace, which is equipped with a stirring device. The molten lead rotates continuously under the stirring of the device, and the surface of the lead (the residual heat after melting) and oxygen in the air continuously undergo oxidation reactions to produce lead powder (lead monoxide). The molten lead loses heat during the flow process and in the powdering furnace. However, to ensure product quality, the temperature needs to be maintained. But heating in the powdering furnace would increase costs. The lead powder is then transported to the next production process through pipes using a cyclone centrifuge. Some of the oxidized lead powder in this type of pulverizing furnace adheres to the furnace wall, requiring periodic forceful tapping and vibration to dislodge it and return it to the molten lead. This type of Pakistani pulverizing furnace relies solely on the oxidation reaction between the molten lead surface and oxygen in the air, resulting in low production efficiency, energy waste, and excessively high production costs. Furthermore, the constant tapping and vibration increases the probability of furnace damage, raising maintenance costs and shortening its lifespan. Lead ingots can only be melted into molten lead for red lead production at high temperatures, a process that consumes significant energy and increases production costs. With intensifying market competition, especially given energy shortages and crises, achieving energy conservation and consumption reduction in red lead production equipment is a pressing issue for the red lead production sector. Summary of the Invention

[0003] This invention provides an integrated energy-saving preparation device for red lead semi-finished products to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an integrated energy-saving preparation device for red lead semi-finished products, comprising a chamber, wherein a horizontally arranged partition is provided inside the chamber, the partition dividing the interior of the chamber into an oxidation chamber and a lead melting chamber, the oxidation chamber being located above the lead melting chamber, a powder outlet pipe being provided at the top of the oxidation chamber, a blower being provided on the outer wall of the oxidation chamber, the outlet of the blower being connected to the oxidation chamber, a liquid outlet being provided on the partition, connecting the oxidation chamber and the lead melting chamber, a feed pipe being provided on the side wall of the chamber, the feed pipe being connected to the lead melting chamber, an electric heating wire being provided inside the lead melting chamber, a temperature sensor being provided on the inner wall of the lead melting chamber, and a controller being provided on the outer wall of the chamber, the signal input terminal of the controller being connected to the temperature sensor, and the signal output terminal being connected to the electric heating wire.

[0007] Furthermore, the driving mechanism includes a limiting strip connected to the lower end of the turntable.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] 1. This invention integrates the two processes of red lead production into one, reducing the number of red lead production steps and labor, which can not only greatly improve the production efficiency of the product, but also reduce the occurrence of occupational hazards by adopting automatic conveying.

[0011] 2. The structure of this invention is simpler, more reasonable, and more scientific than the traditional red lead production device structure, thereby reducing the investment cost of equipment in the field of red lead production.

[0012] 3. This invention uses an electric furnace wire, a controller, and a temperature sensor to jointly control the temperature, keeping it within a certain range. This achieves both melting and energy saving. Furthermore, the oxidation of the lead liquid in the oxidation chamber fully utilizes the residual heat after melting.

[0013] 4. This invention uses a drive mechanism to drive the chamber to reciprocate left and right in an arc-shaped manner. When the chamber moves back and forth, it drives the lead melting chamber inside the device to move, causing the molten lead to move as well, thereby accelerating the melting speed of lead ingots, achieving the purpose of energy saving and consumption reduction, and thus saving the production cost of red lead. At the same time, when the chamber moves back and forth, it drives the oxidation chamber inside the device to move, causing the molten lead inside the chamber to rotate along the chamber wall in a "U" shape, thereby increasing the surface area of ​​the molten lead and the contact area with air, accelerating the reaction efficiency, increasing production capacity, and further achieving the purpose of energy saving, consumption reduction, and improved production efficiency.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-4 The present invention provides the following technical solutions:

[0021] Example 1

[0022] An integrated energy-saving preparation device for red lead semi-finished products includes a chamber 9. A horizontally arranged partition 10 is installed inside the chamber 9, dividing the interior of the chamber 9 into an oxidation chamber 8 and a lead melting chamber 16. The oxidation chamber 8 is located above the lead melting chamber 16. A powder outlet pipe 7 is installed at the top of the oxidation chamber 8. A blower 17 is installed on the outer wall of the oxidation chamber 8, and the outlet of the blower 17 is connected to the oxidation chamber 8. A liquid outlet 6 is provided on the partition 10, connected to the oxygen... The melting chamber 8 and the lead melting chamber 16 are connected by a feed pipe 3 on the side wall of the chamber 9. The feed pipe 3 is connected to the lead melting chamber 16. The lead melting chamber 16 is equipped with an electric heating wire 13. The inner wall of the lead melting chamber 16 is equipped with a temperature sensor 11 to detect the temperature inside the lead melting chamber 16 so as to raise or stop the heating. The outer wall of the chamber 9 is equipped with a controller 12. The signal input terminal of the controller 12 is connected to the temperature sensor 11, and the signal output terminal is connected to the electric heating wire 13.

[0023] Specifically, lead ingots are added into the melting chamber 16 of the silo 9 through the feed pipe 3. Heating is achieved by the heating element 13, raising the temperature of the melting chamber 16 to 380℃-450℃, melting the lead ingots into molten lead. The heating element 13, controller 12, and temperature sensor 11 jointly control the temperature. When the temperature inside the melting chamber 16 exceeds 450℃, the temperature sensor 11 transmits a signal to the controller 12, which automatically shuts off the heating element 13. When the temperature falls below 380℃, an automatic alarm is triggered, and the temperature sensor 11 transmits a signal to the controller 12, which then controls the flow. The lead melt is heated by an electric heating wire 13 and enters the oxidation chamber 8 through the outlet 6. Air is introduced by the blower 17. The lead melt surface reacts continuously with oxygen in the air at high temperature to produce lead oxide powder. The powder is then discharged from the powder outlet pipe 7 by an exhaust fan. The oxidation of the lead melt in the oxidation chamber 8 is achieved by making full use of the residual heat after the lead melt is melted. The oxidation chamber 8 is connected to the lead melting chamber 16, which ensures the constant temperature of the lead melt in the oxidation chamber 8, thereby achieving the purpose of energy saving and consumption reduction and ensuring product quality.

[0024] Example 2

[0025] As an optional case, please refer to Figure 2-3An integrated energy-saving preparation device for lead ingot semi-finished products is disclosed. A valve 5, which is a butterfly valve, is provided at the upper end of the feed pipe 3 to facilitate the entry of lead ingots into the feed pipe 3. A turntable 2 is fixedly installed at the lower end of the chamber 9. A rotating shaft 15 is fixedly connected to the lower end of the turntable 2. A base 1 is rotatably connected to the lower end of the rotating shaft 15. A drive mechanism 14 is provided at the lower end of the turntable 2. The drive mechanism 14 includes a limiting bar 142 connected to the lower end of the turntable 2. Two sets of limiting bars 142 are provided. A groove is provided between the two sets of limiting bars 142. A rotating wheel 146 is rolled in the groove. A support rod 143 is rotatably connected to the lower end of the rotating wheel 146. A rotating plate 141 is provided at the lower end of the support rod 143. A rotating rod 144 is provided at the lower end of the rotating plate 141. The rotating rod 144 is connected to the output end of a motor 145 through a coupling. The motor 145 is fixed to the upper end of the base 1.

[0026] Specifically, the rotation of the motor 145 drives the rotating rod 144 to rotate, which in turn drives the rotating plate 141 and the support rod 143 to rotate. This causes the rotating wheel 146 on the support rod 143 to drive the limiting strip 142 to move, thereby causing the turntable 2 connected to the upper end of the limiting strip 142 and the bin 9 to reciprocate left and right in an arc-shaped manner. When the bin 9 moves back and forth, it drives the lead melting chamber 16 in the device to move, causing the molten lead to move as well, thereby accelerating the melting speed of the lead ingots, achieving the purpose of energy saving and consumption reduction, and thus saving the production cost of red lead. At the same time, when the bin 9 moves back and forth, it drives the oxidation chamber 8 in the device to move, causing the molten lead in the bin to rotate along the bin wall in a "U" shape, thereby increasing the surface area of ​​the molten lead and the contact area with air, accelerating the reaction efficiency, increasing production capacity, and further achieving the purpose of energy saving, consumption reduction and production efficiency improvement.

[0029] As an optional case, please refer to Figure 4 An integrated energy-saving preparation device for red lead semi-finished products is provided. A conveying mechanism 4 is provided above the valve 5. The conveying mechanism 4 includes a limiting shell 43. The upper end of the limiting shell 43 is the inlet, and the lower end is provided with a discharge hopper 44 near the valve 5. The discharge hopper 44 is located above the valve 5. The two sides of the limiting shell 43 serve to limit the lead ingots and prevent them from falling. A conveyor belt 41 is provided inside the limiting shell 43. The conveyor belt 41 is driven by a drive motor. A limiting plate 42 is provided on the conveyor belt 41.

[0030] Specifically, lead ingots are automatically conveyed by the conveying mechanism 4, reducing manual labor and occupational hazards. The lead ingots are placed between the limiting plates 42. When the limiting housing 43 rotates above the discharge hopper 44, they fall from the discharge hopper 44 into the valve 5.
