Abstract
Description
Technical Field
[0001] This utility model relates to the field of anode carbon block roasting equipment, specifically an auxiliary air intake device for a cold air blower. Background Technology
[0002] Because the temperature inside the roasting furnace is high during the roasting process of the anode carbon blocks, it is necessary to meet the roasting requirements. After the anode carbon blocks are roasted, the furnace needs to be opened to remove them, thus completing the roasting process. However, the residual temperature in the roasting furnace is very high after roasting. If the temperature is allowed to drop naturally, it would take a long time, which is insufficient for subsequent roasting of other anode carbon blocks. Therefore, the roasting furnace needs to be cooled. Current methods use cold air blowers to circulate air and lower the temperature within the furnace, allowing it to be opened. However, the anode carbon block roasting furnace is large, and even if air is circulated from a single location, it still takes a long time to achieve the desired cooling effect. This is mainly because the anode carbon blocks are relatively stacked within the furnace, resulting in uneven cooling across different locations and a prolonged cooling time.
[0003] Based on the above problems, there is a need for an auxiliary air intake device for the air cooler, which can be set up to allow the low-temperature gas delivered by the air cooler to the roasting furnace to diffuse better in the roasting furnace, thereby effectively reducing the temperature of the air in the roasting furnace and the temperature of the anode carbon blocks, shortening the cooling time of the roasting furnace and accelerating the roasting production efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide an auxiliary air intake device for a cold air blower. It can be configured on the basis of the cold air blower so that the low-temperature gas delivered by the cold air blower to the roasting furnace can better diffuse in the roasting furnace, thereby effectively reducing the temperature of the air in the roasting furnace and the temperature of the anode carbon block, so as to shorten the cooling time of the roasting furnace and accelerate the roasting production efficiency.
[0005] To achieve the above objectives, this utility model employs the following technical solution:
[0006] An auxiliary air intake device for a blast cooler includes an air intake pipe, which is vertically installed on one side of a roasting furnace. A spiral guide pipe is installed inside the air intake pipe, with its two ends rotatably positioned at the upper and lower ends of the air intake pipe. A blade assembly is installed at the upper end of the spiral guide pipe. An air outlet is provided on the side of the air intake pipe, and multiple air outlets are equally spaced in the vertical direction of the air intake pipe.
[0007] The spiral guide pipe is disposed in a non-contact manner with the inner wall of the air inlet pipe, and a spiral guide groove is provided on the spiral guide pipe, with multiple spiral guide grooves arranged in a circumferential array.
[0008] The apertures of the multiple air outlets increase vertically from top to bottom.
[0009] A limiting frame is provided at the upper end of the air inlet pipe. The limiting frame is erected at the upper end of the air inlet pipe, and the upper end of the spiral guide pipe is rotatably connected to the limiting frame.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] When this device is installed, the cold air delivered by the air cooler is transported into the roasting furnace through the air inlet duct. A spiral guide tube is installed inside the air inlet duct, along with a counter-rotating blade assembly. When the cold air enters the air inlet duct through the delivery pipe, it drives the blade assembly to rotate, causing the spiral guide tube to rotate synchronously. The high-velocity cold air is buffered by the spiral guide tube, allowing it to spiral within the air inlet duct. When the cold air passes the air outlet located on the side of the air inlet duct, the rapidly rotating cold air is thrown out from the outlet, thus buffering the vertical cold air flow and directing it towards the air outlet on the side of the air inlet duct. This effectively delivers cold air to different depths within the roasting furnace, achieving rapid cooling of the furnace. Attached Figure Description

[0018] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.
[0019] Because the temperature of the anode carbon blocks is high during the roasting process, it is necessary to cool them down rapidly after roasting to provide space for subsequent roasting and maximize the roasting efficiency. However, the traditional method of directly inputting cold air is difficult to effectively reduce the temperature in the roasting furnace, and it still takes a long time to reach the required temperature for furnace opening. Therefore, the following settings are required for this device:
[0020] An auxiliary air intake device for a evaporative air cooler includes an air intake pipe 1, which is vertically positioned on one side of a roasting furnace. A spiral guide pipe 2 is installed inside the air intake pipe 1, with its two ends rotatably positioned at the upper and lower ends of the air intake pipe 1. A blade assembly 3 is installed at the upper end of the spiral guide pipe 2. An air outlet 4 is provided on the side of the air intake pipe 1, and multiple air outlets 4 are evenly spaced along the vertical direction of the air intake pipe 1. In operation, the evaporative air cooler first delivers cold air into the air intake pipe 1 through a delivery pipe. When the cold air passes the end of the air intake pipe 1, the entry of the cold air drives the blade assembly 3 to rotate, thereby causing the blade assembly 3 to synchronously rotate the spiral guide pipe 2 inside the air intake pipe 1. At this time, the cold air entering the air intake pipe 1 is buffered by the direct force of the blade assembly 3 and the spiral guide pipe 2, and then rotates spirally within the air intake pipe 1 along with the spiral guide pipe 2. When the cold air following the rotation of the spiral guide pipe 2 passes through the air outlet 4 on the air inlet pipe 1, the rotating cold air is thrown out from the air outlet 4 and enters the roasting furnace to cool its temperature. For the purpose of this arrangement, because the air inlet pipe 1 is vertically oriented and has multiple air outlets 4, the cold air can flow out simultaneously from multiple air outlets 4, thus affecting a larger area of the roasting furnace space. Simultaneously, the spiral guide pipe 2 and blade assembly 3 within the air inlet pipe 1 buffer the direct force of the cold air, preventing it from rushing out directly from the unobstructed port of the air inlet pipe 1, thus avoiding the problem of some areas cooling faster than others.
[0021] The above structure will be further designed and optimized:
[0022] The spiral guide pipe 2 is disposed in a non-contact manner with the inner wall of the air inlet pipe 1, and a spiral guide groove 5 is provided on the spiral guide pipe 2. Multiple spiral guide grooves 5 are arranged in a circumferential array. The spiral guide pipe 2 can better buffer the direct flow of cold air, so that the cold air can effectively flow outward from the air outlet 4 instead of exerting force on the end of the air inlet pipe 1.
[0023] The apertures of the multiple air outlets 4 are vertically enlarged from top to bottom. Because hot air in the roasting furnace rises and diffuses, the gas exhaust system uses a hot air exhaust pipe located at the top of the furnace. This requires the cold air, when exhausted from the furnace, to cover more of the furnace space for cooling. The vertically enlarging apertures of the multiple air outlets 4 allow more cold air to enter the furnace from the bottom, ensuring that the cold air, when exhausted with the exhaust system, covers more of the furnace's interior space, resulting in better cooling within the furnace.
[0024] A limiting frame is provided at the upper end of the air inlet pipe 1. The limiting frame is erected at the upper end of the air inlet pipe 1, and the upper end of the spiral guide pipe 2 is rotatably connected to the limiting frame to meet the rotational stability of the spiral guide pipe 2.
[0025] Therefore, an auxiliary air intake device for a cold air blower can be configured to allow the low-temperature gas delivered by the cold air blower to the roasting furnace to diffuse better in the roasting furnace, thereby effectively reducing the temperature of the air in the roasting furnace and the temperature of the anode carbon blocks, thus shortening the cooling time of the roasting furnace and accelerating the roasting production efficiency.
