Description

Technical Field

[0001] The invention relates to the technical field of coke pushing detection, in particular to a liquid-air comprehensive coke pushing detection cooling tower. Background Art

[0002] In order to perform linear sampling of the furnace wall, a cooling tower is installed on the coke pushing rod to effectively protect the sampling probe and prevent the high temperature from affecting the probe itself.

[0003] A Chinese patent discloses a coke oven status collection system during the coke pushing process, and its publication number is (CN118109213B). The patent uses air cooling technology to form a protective atmosphere around the collection mechanism to protect the collection probe and drive the probe to rotate perpendicular to the side wall for linear collection, which can well solve the rotation problem and the problem of the influence of external temperature on the probe. However, when the self-heating problem of the equipment used is large, the elastic ball sleeve causes the temperature of the equipment to be unable to dissipate, so that the disclosed patent can be applied to the collection probe with low heat generation. However, for the collection equipment with high heat generation, since the temperature of the collection equipment itself is difficult to reduce, it cannot be applied to the collection equipment with high heat generation, resulting in a reduction in the scope of application and expansibility. Summary of the invention

[0004] The object of the present invention is to provide a liquid-air comprehensive coke pushing detection cooling tower to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A liquid-air comprehensive coke pushing detection cooling tower comprises a coke pushing rod, wherein an air inlet path, a return air path, a liquid inlet path, and a liquid return path are arranged in the coke pushing rod, a sandwich tower connected to the air inlet path is arranged on the top of the coke pushing rod, the sandwich tower is connected to the return air path through an exhaust pipe, one end of the exhaust pipe is eccentrically fixedly connected to the top surface of the sandwich tower, four turning grooves are opened on the sandwich tower, the four turning grooves are divided into two groups, the two groups of turning grooves are in opposite directions, and the turning grooves in opposite directions are staggered along the axial direction of the sandwich tower, an observation cabin is rotatably connected in the turning groove, and the two turning grooves in the same direction are fixedly connected by a connecting rod;

[0007] A cold liquid pipe is arranged at the center of the sandwich tower, and four covering connecting shells are rotatably connected to the cold liquid pipe. A collecting lens is fixedly connected inside the covering connecting shell. The lens cover of the collecting lens is fixedly connected to the observation chamber. The top end of the cold liquid pipe is connected to the sandwich tower, and the bottom end of the sandwich tower is connected to the return liquid path.

[0008] As a further solution of the present invention: there is a gap between the observation chamber and the covering connecting shell, and a fan blade is fixedly connected to the bottom of the inner wall of the observation chamber located at the bottom.

[0009] As a further solution of the present invention: the cold liquid pipe and the sandwich tower are fixedly connected via a fixing rod.

[0010] As a further solution of the present invention: a plurality of arcuate gear rods A are fixedly connected to one of the connecting rods, and a plurality of arcuate gear rods B are fixedly connected to the other connecting rod, and a reversing gear is arranged between the arcuate gear rods A and the arcuate gear rods B, and the reversing gear is respectively engaged with the arcuate gear rods A and the arcuate gear rods B.

[0011] As a further solution of the present invention: the sandwich tower comprises an outer tube component and an inner tube component, the top of the inner tube component is closed by an inner top head, the top of the outer tube component is closed by an outer top head, the groove body between the outer tube component and the inner tube component is closed by a groove closing component, the top of the inner top head is provided with a liquid inlet body connected to the cold liquid pipe, the top of the inner top head is provided with an inner closed hole body fixedly connected to the exhaust pipe, and the top of the outer top head is provided with an outer closed hole body fixedly connected to the exhaust pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The cold liquid pipe is located at the center of the sandwich tower. The cold liquid pipe is least affected by the temperature in the furnace. At this time, the temperature of the cold liquid pipe is at the lowest state, and the temperature difference between the cold liquid pipe and the collection lens is the largest, so the heat exchange efficiency is the highest. At the same time, the wind channel forms a second temperature protection layer on the outside of the cold liquid pipe, which further reduces the temperature impact of the outside temperature on the cold liquid pipe, ensuring that the warehouse of the collection lens is always in the most efficient state of heat exchange. Since the sandwich tower also has a sandwich cavity, the liquid in the cold liquid pipe begins to increase its own temperature as the height increases. When it reaches the top, the temperature has risen. The increased coolant flows naturally through the inner wall of the sandwich tower, thereby forming an outer barrier at the sandwich tower. The cooling barrier layers from outside to inside are respectively the heating coolant protection layer, the air cooling layer and the low-temperature coolant heat exchange layer, thereby effectively protecting the collection lens to complete the operation at high temperature, and can also solve the self-heating problem of the collection lens. The system adopts dual cooling media to ensure that the high-temperature protection effect is improved while solving the self-heating heat exchange problem of the equipment under the premise of the structure of the observation warehouse and the collection lens rotating. The acquisition lens can be replaced with a device with a high self-heating temperature, thus increasing the scope of application and scalability of the system. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] See also Figure 1-Figure 9In the present embodiment, a coke pushing rod 3 is included, in which an air inlet path, an air return path, a liquid inlet path, and a liquid return path are arranged. A sandwich tower 1 connected to the air inlet path is arranged on the top of the coke pushing rod 3. The sandwich tower 1 is connected to the return air path through an exhaust pipe 2. One end of the exhaust pipe 2 is eccentrically fixedly connected to the top surface of the sandwich tower 1. Four turning grooves 11 are provided on the sandwich tower 1. The four turning grooves 11 are divided into two groups. The two groups of turning grooves 11 are in opposite directions, and the turning grooves 11 in opposite directions are staggered along the axial direction of the sandwich tower 1. An observation cabin 5 is rotatably connected in the turning groove 11, and the two turning grooves 11 in the same direction are fixedly connected by a connecting rod 4.

[0026] In this embodiment: the sandwich tower 1 and the exhaust pipe 2 are connected, the wind enters from the bottom of the sandwich tower 1 and flows upward, flows back through the exhaust pipe 2, and is discharged through the return air path in the coke pushing rod 3, thereby forming an air cooling surrounding layer. The purpose of the observation chamber 5 is to cooperate with the collection lens 7 to rotate, so that the collection lens 7 can realize the collection in the front and side directions, and is applied to the dual collection mode of vertical collection in the early stage of coke pushing and collection of the furnace wall during movement in the furnace.

[0027] In this embodiment: a cold liquid pipe 6 is arranged at the center of the sandwich tower 1, and four covering connecting shells 62 are rotatably connected to the cold liquid pipe 6, and a collecting lens 7 is fixedly connected inside the covering connecting shell 62. The lens cover of the collecting lens 7 is fixedly connected to the observation chamber 5, the top end of the cold liquid pipe 6 is connected to the sandwich tower 1, and the bottom end of the sandwich tower 1 is connected to the return liquid path.

[0028] In this embodiment: in order to form a liquid cooling passage in the middle of the cold liquid pipe 6, the cold liquid pipe 6 is divided into a multi-section structure, and a covering connecting shell 62 is rotated between the two sections. The upper and lower ends of the covering connecting shell 62 are both pipe structures, and the middle part of the covering connecting shell 62 has a sandwich cavity, and the liquid can enter the covering connecting shell 62 through the cold liquid pipe 6 and enter the inside of another section of the cold liquid pipe 6. The covering connecting shell 62 is provided with a cavity for accommodating the installation of the collection lens 7. The liquid is divided after passing through the covering connecting shell 62, and the covering connecting shell 62 contacts the outer shell of the collection lens 7, thereby taking away a large amount of heat. At this time, the cold liquid pipe 6 is located at the center of the sandwich tower 1, and the cold liquid pipe 6 is least affected by the temperature in the furnace. At this time, the temperature of the cold liquid pipe 6 is at the lowest state, and the temperature difference between the cold liquid pipe 6 and the collection lens 7 is the largest, so that the heat exchange efficiency is the highest. At the same time, the wind passage forms a second temperature protection layer on the outside of the cold liquid pipe 6, so that the influence of the external temperature on the temperature of the cold liquid pipe 6 is further reduced, ensuring that the warehouse of the collection lens 7 is always in the most efficient state of heat exchange. Since the sandwich tower 1 also has a sandwich cavity, the temperature of the liquid in the cold liquid pipe 6 begins to rise as the height increases. When it reaches the top, the temperature has risen. The raised cooling liquid naturally flows down through the inner wall of the sandwich tower 1, thereby forming an outer barrier at the sandwich tower 1. The cooling barrier layers from the outside to the inside are respectively a warming cooling liquid protection layer, an air cooling layer, and a low-temperature cooling liquid heat exchange layer, thereby effectively protecting the collection lens 7 from completing the operation at high temperatures, and can also solve the self-heating problem of the collection lens 7. The system uses dual cooling media to ensure that the high-temperature protection effect is improved while solving the self-heating heat exchange problem of the equipment under the premise of ensuring the self-rotation of the observation chamber 5 and the collection lens 7. The collection lens 7 can be replaced with equipment with high self-heating temperature, and the scope of application and expansibility of the system are increased.

[0029] In the present embodiment: there is a gap between the observation bin 5 and the covering connecting shell 62, and a fan blade 8 is fixedly connected to the bottom of the inner wall of the observation bin 5 located at the bottom, a plurality of arcuate gear rods A41 are fixedly connected to one of the connecting rods 4, and a plurality of arcuate gear rods B42 are fixedly connected to the other connecting rod 4, and a reversing gear 43 is arranged between the arcuate gear rods A41 and B42, and the reversing gear 43 is respectively meshed with the arcuate gear rods A41 and B42.

[0030] In this embodiment: a fan blade 8 is set at the bottom of the lowest observation bin 5. When high-speed wind blows out from the coke pushing rod 3, the wind will drive the fan blade 8 to rotate, thereby rotating the lowest observation bin 5. Since the observation bins 5 are grouped in pairs, after the two observation bins 5 in the same direction rotate, the arc-shaped gear rod A41 is driven to rotate through the connecting rod 4, and the reversing gear 43 rotates on its own, so that the arc-shaped gear rod B42 drives another connecting rod 4 to rotate, and the other connecting rod 4 drives the two observation bins 5 in opposite directions to rotate, thereby realizing collection on both sides of the wall.

[0031] In this embodiment: the cold liquid pipe 6 and the sandwich tower 1 are fixedly connected by a fixing rod 61; the cold liquid pipe 6 is divided into multiple sections under the influence of the covering connecting shell 62, so the cold liquid pipe 6 and the sandwich tower 1 are fixed by the fixing rod 61 to ensure the stability of the cold liquid pipe 6.

[0032] In this embodiment: the sandwich tower 1 includes an outer tube component 101 and an inner tube component 102, the top of the inner tube component 102 is closed by an inner top head 104, the top of the outer tube component 101 is closed by an outer top head 105, the groove body between the outer tube component 101 and the inner tube component 102 is closed by a groove closing component 103, the top of the inner top head 104 is provided with a liquid inlet hole body connected to the cold liquid pipe 6, the top of the inner top head 104 is provided with an inner closed hole body fixedly connected to the exhaust pipe 2, and the top of the outer top head 105 is provided with an outer closed hole body fixedly connected to the exhaust pipe 2.

[0033] In this embodiment: the outer tube component 101 and the inner tube component 102 are two pipes with different inner diameters and outer diameters. Turning grooves 11 are cut on the outer tube component 101 and the inner tube component 102 respectively. The top of the inner tube component 102 can be welded with an inner top cap 104 and two holes are opened. First, weld the groove closing component 103 to the outside of the inner tube component 102, then sleeve the inner tube component 102 on the outside of the cold liquid pipe 6, and weld the top of the cold liquid pipe 6 to the inner top head 104. First, weld the inner tube component 102 and the inner top head 104, then sleeve the outer tube component 101 on the outside of the inner tube component 102, and pass the outer top head 105 through the exhaust pipe 2, weld the exhaust pipe 2 to the side hole of the inner top head 104 first, then weld the groove closing component 103 to the outer tube component 101, and finally weld the outer top head 105 to the outer tube component 101 and the outer top head 105 to the exhaust pipe 2. Similarly, welding can also be replaced with a detachable connection form, which can further increase the expandability.

[0034] In this embodiment: Please refer to Figure 4 , Figure 5 The air inlet of the coke pushing rod 3 is large, and the liquid delivery pipeline of the coke pushing rod 3 is located in the air inlet channel. The air inlet of the coke pushing rod 3 is provided with an annular groove, which is connected to the interlayer cavity of the interlayer tower 1. The outer layer of cooling liquid flowing out of the interlayer cavity enters the annular groove, and only a liquid return pipeline needs to be set on the side of the annular groove. The position of the return air pipe connected to the exhaust pipe 2 can be set according to the needs.
