Description

Technical Field

[0001] This utility model relates to the field of carbon brick cooling technology, and in particular to a carbon brick cooling air duct structure. Background Technology

[0002] Charcoal bricks require cooling during production to ensure stable performance. Existing cooling ducts for charcoal bricks are mostly single-channel structures, resulting in uneven airflow and poor cooling efficiency. Furthermore, dust and other impurities carried by the cooling air easily accumulate in the ducts, causing blockages, further affecting cooling performance, and increasing maintenance costs. In addition, existing ducts cannot adjust the direction and flow rate of the cooling air according to the cooling needs of the charcoal bricks, lacking flexibility. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a carbon brick cooling duct structure that effectively solves the problems of poor carbon brick cooling effect and poor flexibility in existing technologies.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: A carbon brick cooling duct structure includes a duct body with at least two layers of transverse partitions inside, dividing the interior of the duct body into three independent cooling channels: upper, middle, and lower. Each cooling channel is equipped with an adjustable-angle guide plate, which is connected to the side wall of the duct body via a rotating shaft. One end of the rotating shaft extends to the outside of the duct body and is connected to an adjustment knob. A self-cleaning device is provided at the air inlet of the duct body. The self-cleaning device includes an annular nozzle and multiple high-pressure nozzles located inside the annular nozzle. The annular nozzle is connected to an external high-pressure air source via a connecting pipe.

[0005] Preferably, the transverse partition has a hollow structure with a hollow ratio of 30%-50%, and the hollow holes are distributed in a honeycomb pattern.

[0006] Preferably, the surface of the guide plate is provided with a nano-coating, which is a polytetrafluoroethylene coating with a thickness of 5-10 μm.

[0007] Preferably, the high-pressure nozzles are evenly distributed along the circumference of the annular nozzle, with a quantity of 4-8, and the spray direction of the nozzles forms an angle of 30°-45° with the axis of the air duct body.

[0008] Preferably, the main body of the air duct is made of high-temperature resistant stainless steel with a thickness of 3-5mm.

[0009] Preferably, the adjustment knob component includes a worm gear rotatably mounted on the air duct body, the worm gear meshing with a worm wheel, and the worm wheel being fixedly connected to a rotating shaft.

[0010] Compared with the prior art, this utility model has the following advantages: 1.

Detailed Implementation

[0014] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figures 1-4 As shown, a carbon brick cooling duct structure includes a duct body 1. The duct body 1 has at least two layers of transverse partitions 5 inside, dividing the interior of the duct body 1 into three independent cooling channels: upper, middle, and lower. Each cooling channel is equipped with an adjustable-angle guide plate 6. The guide plate 6 is connected to the side wall of the duct body 1 via a rotating shaft 10. One end of the rotating shaft 10 extends to the outside of the duct body 1 and is connected to an adjustment knob component. A self-cleaning device is provided at the air inlet 11 of the duct body 1. The self-cleaning device includes an annular nozzle 2 and multiple high-pressure nozzles 4 located inside the annular nozzle 2. The annular nozzle 2 is connected to an external high-pressure air source via a connecting pipe 3.

[0016] When this utility model is in use, the cooling air enters from the air inlet 11 of the air duct body 1. During the entry process, if the air duct body 1 has just been started or does not require cleaning, the self-cleaning device is in the closed state, and the cooling air smoothly enters the interior of the air duct body 1. After entering the main body of the air duct 1, the cooling air encounters the three independent cooling channels (upper, middle, and lower) formed by the horizontal baffle 5 and flows into each channel respectively. In each cooling channel, the adjustable-angle guide plate 6 plays a role. According to the specific situation of the carbon brick to be cooled, the operator can rotate the rotating shaft 10 by rotating the adjustment knob on the outside of the air duct body 1, thereby changing the angle of the guide plate 6. The change of the angle of the guide plate 6 will adjust the flow direction and flow rate of the cooling air in the channel, ensuring that the cooling air can be accurately blown to the part of the carbon brick that needs to be cooled, thus improving the cooling efficiency. Cooling air flows through each channel, exchanges heat with the charcoal bricks, and is then discharged from the air outlet of the main air duct 1. A temperature sensor is installed at the air outlet of the main air duct 1. The temperature sensor at the air outlet monitors the temperature of the discharged gas in real time and transmits the temperature signal to the external control system. The staff obtains the temperature data through the external control system to understand the cooling status of the charcoal bricks. If the temperature does not reach the expected cooling effect, the cooling parameters can be adjusted again by adjusting the angle of the guide plate 6 until the cooling of the charcoal bricks meets the requirements.

[0017] After the main body of the air duct 1 has been used for a period of time, dust and other impurities may accumulate inside. At this time, the self-cleaning device is turned on, and the external high-pressure air source delivers high-pressure gas to the annular nozzle 2 through the connecting pipe 3. The high-pressure gas is then ejected through multiple high-pressure nozzles 4 inside the annular nozzle 2.

[0018] The transverse partition 5 has a hollow structure with a hollow rate of 30%-50%, and the hollow holes 12 are distributed in a honeycomb pattern.

[0019] like Figure 2 As shown, since the transverse partition 5 has a hollow structure with a hollow rate of 30%-50%, the honeycomb-shaped hollow holes 12 allow some cooling air to circulate appropriately between the channels, thereby supplementing and regulating the airflow, while avoiding excessive interference between the airflows of each channel.

[0020] The surface of the guide plate 6 is provided with a nano-coating, which is a polytetrafluoroethylene coating with a thickness of 5-10 μm.

[0021] like Figure 2 and 4 As shown, the non-stick properties of the coating reduce the adhesion of dust in the cooling air, while the wear resistance extends the service life of the deflector plate 6 and reduces the difficulty of cleaning and maintenance.

[0022] The high-pressure nozzles 4 are evenly distributed around the circumference of the annular nozzle 2, with a quantity of 4-8, and the spray direction of the nozzles forms an angle of 30°-45° with the axis of the air duct body 1.

[0023] like Figure 1 and 4 As shown, since the number of high-pressure nozzles 4 evenly distributed around the annular nozzle 2 is preferably 6, and the spray direction is preferably at a 45° angle with the axis of the air duct body 1, the sprayed high-pressure gas can thoroughly blow the inside of the air duct body 1, clean up the accumulated dust and other impurities from the air outlet, complete the self-cleaning of the air duct body 1, and ensure the normal operation of subsequent cooling work.

[0024] The main body of the air duct 1 is made of high-temperature resistant stainless steel with a thickness of 3-5mm.

[0025] like Figure 1 As shown, the main body of the air duct 1 is made of 3-5mm thick high-temperature resistant stainless steel. It can withstand the high-temperature environment when the carbon brick is cooled due to its high-temperature resistance, and its good corrosion resistance extends the service life of the air duct. At the same time, the appropriate thickness ensures the structural strength and ensures the stable operation of the air duct.

[0026] The adjustment knob component includes a worm gear 8 rotatably mounted on the air duct body 1, the worm gear 8 meshing with a worm wheel 9, and the worm wheel 9 being fixedly connected to a rotating shaft 10.

[0027] like Figure 2 and 4 As shown, a handle 7 is provided at one end of the worm 8. The handle 7 drives the worm 8 to rotate, which in turn drives the worm wheel 9 to rotate. The worm wheel 9 drives the guide plate 6 to rotate through the rotating shaft 10, thereby adjusting the angle of the guide plate 6.

[0028] The working process of this utility model is as follows: Cooling air enters from the air inlet 11 of the air duct body 1. During the entry process, if the air duct body 1 has just been started or does not require cleaning, the self-cleaning device is in the closed state, and the cooling air smoothly enters the interior of the air duct body 1.

[0029] After entering the main body of the air duct 1, the cooling air encounters the upper, middle and lower independent cooling channels formed by the horizontal partition 5 and flows into each channel respectively. Since the horizontal partition 5 has a hollow structure with a hollow rate of 30%-50%, the honeycomb-shaped hollow holes 12 allow some of the cooling air to circulate appropriately between the channels, so as to achieve airflow supplementation and regulation, while avoiding excessive mutual interference between the airflow of each channel. Within each cooling channel, an adjustable baffle plate 6 plays a crucial role. Depending on the specific condition of the carbon bricks to be cooled, the operator can rotate the adjustment knob on the outside of the air duct body 1 to drive the rotating shaft 10 to rotate, thereby changing the angle of the baffle plate 6. The change in the angle of the baffle plate 6 will adjust the flow direction and flow rate of the cooling air in the channel, ensuring that the cooling air can be accurately blown to the parts of the carbon bricks that need to be cooled, thus improving cooling efficiency. In addition, the polytetrafluoroethylene nano-coating on the surface of the baffle plate 6 can reduce the adhesion of dust in the cooling air to its surface.

[0030] Cooling air flows through each channel, exchanges heat with the carbon bricks, and is then discharged from the air outlet of the main air duct 1. At this time, the temperature sensor at the air outlet will monitor the temperature of the discharged gas in real time and transmit the temperature signal to the external control system. The staff can obtain temperature data through the external control system to understand the cooling status of the carbon bricks. If the temperature does not reach the expected cooling effect, the cooling parameters can be adjusted again by adjusting the angle of the guide plate 6, etc., until the cooling of the carbon bricks meets the requirements. After the main body of the air duct 1 has been used for a period of time, dust and other impurities may accumulate inside. At this time, the self-cleaning device is turned on, and the external high-pressure air source delivers high-pressure gas to the annular nozzle 2 through the connecting pipe 3. The high-pressure gas is sprayed out through multiple high-pressure nozzles 4 on the inner side of the annular nozzle 2. Since the high-pressure nozzles 4 are evenly distributed around the annular nozzle 2 and the spray direction is at an angle of 30°-45° with the axis of the main body of the air duct 1, the sprayed high-pressure gas can thoroughly blow the inside of the main body of the air duct 1, cleaning out the accumulated dust and other impurities from the air outlet, completing the self-cleaning of the main body of the air duct 1, and ensuring the normal operation of subsequent cooling work.
