[0002] As one of the most widely used copper smelting furnaces, the main area of reaction of the flash furnace is the reaction tower, and the reaction occurs in a very short time after the dry material and oxygen-rich air are mixed inside the reaction tower.

DETAILED DESCRIPTION

[0027] With reference to the drawings and embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. In the case of no conflict, the embodiments and features in the embodiments can be combined with each other. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present application.

[0028] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture, and if the certain posture changes, the directional indications will also change accordingly.

[0029] Referring to Figures 1-5 As shown in the figure, a new high-strength flash smelting furnace reaction tower structure includes a reaction tower body composed of a plurality of cylinder bodies 1 and a copper water jacket layer 2, and a concentrate nozzle 3 is arranged at the top of the reaction tower body. The copper water jacket layer 2 includes a plurality of copper water jacket bodies 21, which are arranged in a circumferential array, and a first water inlet pipe 22 and a first water outlet pipe 23 are arranged on the copper water jacket body 21. A thermometer for detecting temperature is arranged on the copper water jacket body 21, and the structure further includes:

[0030] A plurality of adjusting water grooves 4, which can be the same in number as the cylinder bodies 1, are arranged in a coverless manner and can be supplemented by rainwater in normal times. The adjusting water grooves 4 are connected to the cylinder bodies 1 through support columns 40 and are connected to the first water inlet pipe 22 for adjusting the water speed of the copper water jacket body 21.

[0031] When the temperature of the reaction tower is high, the heat exchange efficiency needs to be improved. At this time, the water flow in the copper water jacket body 21 can be increased by adjusting the water grooves 4, so as to increase the overall water flow speed in the copper water jacket body 21 and improve the heat exchange efficiency. Similarly, if it is necessary to reduce the heat exchange efficiency, the copper water jacket body 21 can be connected to the adjusting water grooves 4. When the cooling water flows in from the first water inlet pipe 22, part of it will flow into the adjusting water grooves 4, thereby reducing the water flow speed and achieving the purpose of reducing the heat exchange efficiency.

[0032] The impurity cleaning assembly is arranged in the adjusting water groove 4 and is used for cleaning the solid waste in the adjusting water groove 4. Since the adjusting water groove 4 is open, it can be supplemented by rainwater in normal times, but other impurities often enter the inside. In order to avoid the impurities flowing into the copper water jacket body 21, the impurities need to be cleaned.

[0033] The clamping piece is arranged on one side of the copper water jacket body 21 and is used for clamping the adjacent copper water jacket body 21.

[0034] The bottom of the reaction tower body is a reaction zone with the highest temperature, and then gradually moves away from the reaction zone upwards, and the temperature also gradually decreases layer by layer. The copper water jacket layer 2 at a high position is often connected in series, and the copper water jacket body 21 is connected in series in a certain number, for example, the first layer at the bottom is connected in series with two in and one out, the second layer is connected in series with four in and one out, the third to twentieth layers are connected in series with four in and one out, and so on. In this way, the flow rate of the cooling water can be changed according to the different temperatures at different heights to meet the corresponding heat exchange efficiency.

[0035] However, in actual process, the temperature in the reaction tower body changes, so that the actual temperature of each layer of copper water jacket body 21 also changes. At this time, using the same water flow rate may cause the local temperature of the furnace body to change suddenly, forming a significant temperature gradient, and then causing serious thermal stress problems. At this time, the water flow rate in the adjusting water tank 4 connected with the copper water jacket body 21 can be controlled.

[0036] In an embodiment, the reaction tower body is arranged axially apart by 21 layers of copper water jacket layers 2 and 20 layers of cylinder bodies 1. The copper water jacket layer 2 is composed of a plurality of copper water jacket bodies 21. The first layer of copper water jacket body 21 at the bottom includes 52 sawtooth-shaped copper-steel composite copper water jackets, the second layer of copper water jacket body 21 includes 52 buried pipe type copper water jackets, each of the third to twentieth layers includes 24 buried pipe type copper water jackets, and the twenty-first layer at the top includes 108 BIC water jackets.

[0037] In an embodiment, the center axial spacing between the first layer of copper water jacket body 21 and the second layer is 28mm, the center axial spacing between the second to fifteenth layers of copper water jacket body 21 is 290mm, the center axial spacing between the fifteenth to twentieth layers of copper water jacket body 21 is 390mm, and the center axial spacing between the twenty-first layer of copper water jacket body 21 and the twentieth layer is 318mm.

[0038] In an embodiment, the adjusting water tank 4 is provided with a second water inlet pipe 5 on one side, and a water pump connected with the second water inlet pipe 5 is arranged in the adjusting water tank 4. The water in the adjusting water tank 4 can be pumped into the copper water jacket body 21. The second water inlet pipe 5 is connected with the first water inlet pipe 22 at the end away from the adjusting water tank 4, and a first control valve 51 is further arranged on the second water inlet pipe 5 for controlling the opening and closing of the second water inlet pipe 5. The adjusting water tank 4 is provided with a second water outlet pipe 6 on the other side, and the second water outlet pipe 6 is connected with the first water inlet pipe 22 at the end away from the adjusting water tank 4. A second control valve 61 is further arranged on the second water outlet pipe 6 for controlling the opening and closing of the second water outlet pipe 6.

[0039] Since the copper jacket body 21 itself adopts a series connection, when adjusting the water flow, if the flow rate needs to be increased, the first copper jacket body 21 in series can be pumped first, and if it still does not meet the requirements, the second copper jacket body 21 in series can also be pumped in until the requirements are met; similarly, when the flow rate needs to be reduced, the first second control valve 61 in series is opened first to make the first water inlet pipe 22 and the second water outlet pipe 6 conductive to achieve water flow splitting and thus reduce the flow rate, and if the requirements are not met, the second second control valve 61 is also opened to increase the flow splitting.

[0040] In an embodiment, a filter screen 41 is arranged in the adjusting water tank 4, which can filter out some solid waste to avoid the solid waste flowing into the copper jacket body 21, and the filter screen 41 is located between the second water inlet pipe 5 and the second water outlet pipe 6, wherein the second water inlet pipe 5 is located at the bottom of the filter screen 41, and the second water outlet pipe 6 is located at the top of the filter screen 41. The side wall of the adjusting water tank 4 is also provided with an overflow channel 8, and the excess water can be discharged from the overflow channel 8. The opening of the overflow channel 8 is provided with a baffle 42 located on the filter screen 41. The baffle 42 is rotatably provided with guide rollers 421 on both sides. The middle part of the guide roller 421 is provided with a rotating shaft, and one end of the rotating shaft is also provided with a driving member for driving. The filter screen 41 is also provided with a push plate 43, and the adjusting water tank 4 is provided with a sliding groove 44. The two sides of the push plate 43 are provided with driving blocks 431 located in the sliding groove 44 and sliding in the sliding groove 44. The driving blocks 431 are provided with driving members, which can make the driving blocks 431 slide back and forth along the sliding groove 44. When a large amount of solid waste accumulates on the filter screen 41, the push plate 43 can be started to scrape and brush the filter screen 41, and the solid waste on the filter screen 41 can be pushed to the baffle 42. The baffle 42 can push the solid waste into the overflow channel 8 for discharge through the rotation of the guide roller 421;

[0041] The outer side of the adjusting water tank 4 is also provided with a connecting water pipe 7, and the connecting water pipe 7 is connected with the adjusting water tank 4 through a conductive pipe 71. The adjusting water tanks 4 are connected with each other through the connecting water pipes 7, so that when one of the adjusting water tanks 4 lacks water, the water can flow between them.

[0042] In an embodiment, the clamping member includes a plug plate 24 located on one side of the copper jacket body 21, and the other side of the copper jacket body 21 is provided with a plug slot 25 matched with the plug plate 24. The outer side of the plug slot 25 is also provided with a grouting hole 28, and the grouting material is high-temperature-resistant grouting material.

[0043] During initial installation, the plug plate 24 on one side is inserted into the plug slot 25 on the other side, and then the grouting material is poured into the grouting hole 28. Compared with the traditional bolt fixing, the steps can be reduced, and the installation is more convenient through the positioning of the plug plate 24.

[0044] In an embodiment, a movable slot is formed in the slot 25, a positioning rod 26 is slidably arranged in the movable slot, an inclined surface is formed on the upward side of the positioning rod 26, a reset spring 27 is arranged at one end of the positioning rod 26, and a positioning hole 241 is formed in the plug-in board 24 and cooperates with the positioning rod 26;

[0045] When the plug-in board 24 is inserted, the plug-in board 24 will push the positioning rod 26 inward along the inclined surface of the positioning rod 26, and then the positioning rod 26 will be inserted into the positioning hole 241 under the elastic force of the reset spring 27 after the plug-in board 24 is completely inserted, thereby completing the preliminary locking and finally being fixed by grouting.

[0046] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application.
