Description

Technical Field

[0001] The present application relates to the technical field of slag flushing pools, and in particular to a slag flushing pool for smelting manganese silicon alloy. Background Art

[0002] A slag flushing pool is a facility used to collect and precipitate metal slag, usually connected to a metallurgical furnace or industrial boiler. For example, after the smelting of manganese silicon alloy is completed, the 1500°C molten slag is discharged from the blast furnace slag outlet and enters the granulation tower through the slag ditch. It is quenched into fine slag by high-pressure water and then falls to the bottom of the slag flushing pool after being cooled, forming a slag-water mixture. The slag flushing pool temporarily stores this slag-water mixture for subsequent processing and utilization.

[0003] Application No. 202320375293.6 discloses a slag flushing pool for smelting manganese silicon alloy, including a water pool, a filter screen, a circulating pump, an exhaust pipe and a circulating pipe, etc. The coolant is poured into the interior of the water pool through the feed port of the water pool, and then the slag is poured into the interior of the water pool through the feed port of the water pool, so that the coolant in the water pool cools the slag, and at the same time, the first motor is turned on, and the first transmission box is driven to make the first spiral conveyor shaft convey the slag from left to right, and then the second motor is turned on, and the second transmission box is driven to make the second spiral conveyor shaft convey the cooled slag to the interior of the conveying pipe, and then the slag is discharged through the discharge port of the conveying pipe, and then the filter device circulates and filters the coolant in the water pool, and at the same time, the water in the steam is recovered through the recovery device, thereby reducing the waste of water resources, reducing the slag recovery cost, and improving the practicality of the equipment.

[0004] However, in use, there are the following defects:

[0005] Although the first screw conveyor shaft and the second screw conveyor shaft are used to convey the slag, due to a certain pitch between the first screw conveyor shaft and the second screw conveyor shaft, part of the slag cannot be captured by the second screw conveyor shaft after entering the gap, resulting in accumulation and inability to be conveyed, affecting the slag recovery efficiency of the device. Utility Model Content

[0006] The purpose of the present application is to provide a slag flushing pool for smelting manganese silicon alloy, which solves the problem proposed in the background technology that although the first screw conveyor shaft and the second screw conveyor shaft are used to convey the slag, due to a certain pitch between the first screw conveyor shaft and the second screw conveyor shaft, part of the slag cannot be captured by the second screw conveyor shaft after entering the gap, resulting in accumulation and inability to be conveyed, affecting the slag recovery efficiency of the device.

[0007] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a manganese silicon alloy smelting slag flushing pool, comprising a pool body, a sliding top cover, a push plate, a drain pipe and a pull-out plate, two slide grooves are provided at the top edges of both sides of the pool body, the bottom protrusion of the sliding top cover is slidably connected on the inner side of the slide groove, a slag inlet is provided on the right side wall of the sliding top cover, and a limiting groove is fixedly installed between the inner side walls of the sliding top cover, a screw rod is movably installed at the bottom of the limiting groove, a cooling box is fixedly installed on the top of the sliding top cover, a heat-absorbing iron plate is fixedly installed on the inner side of the cooling box, and a cooling fan is fixedly installed on the outer side wall of the cooling box, a separation groove is provided on the left side of the inner bottom of the pool body, a partition is fixedly installed on the inner side wall of the pool body above the separation groove, and a plurality of water-permeable holes are evenly provided on the surface of the partition.

[0008] In this technical solution, the sliding top cover slides horizontally on the top of the pool body and is initially located at the rightmost side of the pool body, and the slag and cooling water are discharged into the pool body along the slag inlet. Under the cover of the left and right baffles at the bottom of the sliding top cover, the filter residue and cooling water are temporarily located on the right side of the pool body. In the process of the sliding top cover sliding to the left, the filter residue and cooling water are driven to move to the left together due to the baffle. The water vapor in the cooling process can be liquefied through the cooling box, the air inlet pipe and the air outlet pipe. The water vapor moves upward along the air inlet pipe into the cooling box. Under the heat absorption of the heat absorbing iron plate, the water vapor will turn back into liquid and move downward through the heat dissipating iron plate and the air outlet pipe and then return to the pool body. Because the sliding top cover is always located above the filter residue, the water vapor can be continuously liquefied, saving water resources while avoiding the problem of water vapor. Leakage can prevent scalding accidents. The slag-liquid separation can be completed through the partitions, water holes and separation grooves. When the sliding top cover slides to the top of the inner partition of the pool body, the slag and cooling water will also arrive. The cooling water will flow along the water holes on the surface of the partition to the separation groove below, separating the filtered slag and cooling water, making the subsequent discharge of the slag more convenient. At the same time, the slag can be easily discharged through the driving motor, screw rod, push plate and slag outlet. After the slag-liquid separation is completed, the pull plate is pulled out from the slag outlet, and then the driving motor drives the screw rod to rotate after power-on, so that the support block and the push plate push the filtered slag to move to the slag outlet, and finally discharged. Since the push plate can cover the slag stacking area, all the slag can be pushed to the slag outlet during the discharge process, avoiding accumulation caused by the four corners, thereby improving the slag discharge efficiency.

[0009] As an optional solution to the technical solution of the present application, the surface of the screw rod is threadedly connected to a support block, the bottom of the support block is fixedly connected to a push plate, a drive motor is fixedly installed on the outer side wall of the sliding top cover facing one end of the screw rod, and the rear end of the transmission shaft of the drive motor is fixedly connected to the screw rod.

[0010] As an optional solution of the technical solution of the present application, baffles are fixedly connected to the left and right sides of the bottom of the sliding top cover, and the baffles are located on the inner side of the pool body and fit against the inner wall of the pool body.

[0011] As an optional solution of the technical solution of the present application, the upper right side wall of the cooling box is connected to one end of the air intake pipe, the other end of the air intake pipe passes through the top of the sliding top cover and is located below the sliding top cover, and the lower left side wall of the cooling box is connected to one end of the air outlet pipe, the other end of the air outlet pipe passes through the left side wall of the sliding top cover and is located on the inner left side wall of the sliding top cover.

[0012] As an optional solution of the technical solution of the present application, the outer wall of the tank body on the left side of the separation tank is connected to a drain pipe.

[0013] As an optional solution of the technical solution of the present application, a slag discharge port is opened on the side wall of the pool body on one side of the partition, the direction of the slag discharge port is parallel to the chute, and a pull-out plate is slidably connected to the inner side of the slag discharge port.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present application can liquefy water vapor in the cooling process through a cooling box, an air inlet pipe and an air outlet pipe. The water vapor moves upward along the air inlet pipe into the cooling box. Under the heat absorption of the heat-absorbing iron plate, the water vapor will turn back into liquid and move downward through the heat-dissipating iron plate and the air outlet pipe and return to the pool body. Since the sliding top cover is always located above the filter residue, the water vapor can be continuously liquefied, saving water resources while avoiding scalding accidents caused by water vapor leakage.

[0016] 2. The present application can complete the slag-liquid separation through partitions, water-permeable holes and separation troughs. When the sliding top cover slides to the top of the inner partition of the pool body, the slag and cooling water will also follow. The cooling water will flow along the water-permeable holes on the surface of the partition to the separation trough below, separating the filtered slag and cooling water, thereby making the subsequent discharge of the slag more convenient.

[0017] 3. The present application can conveniently discharge slag through the driving motor, screw rod, push plate and slag outlet. After the slag-liquid separation is completed, a pull plate is pulled out from the slag outlet, and then the driving motor drives the screw rod to rotate after power-on, so that the support block and the push plate push the filtered slag to move toward the slag outlet and finally discharge it. Since the push plate can cover the slag stacking area, all the slag can be pushed to the slag outlet during the discharge process, avoiding accumulation caused by the four corners, thereby improving the slag discharge efficiency.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, they are further explained below in conjunction with specific implementation methods.

[0024] like Figure 1 As shown, a manganese-silicon alloy smelting slag flushing pool includes a pool body 1, a sliding top cover 3, a push plate 13, a drain pipe 17 and a pull-out plate 19, two slide grooves 2 are opened on the top edges of both sides of the pool body 1, and the bottom protrusion of the sliding top cover 3 is slidably connected on the inner side of the slide groove 2, and a cooling fan 9 is fixedly installed on the outer wall of the cooling box 6, and the cooling fan 9 can accelerate the heat dissipation of the cooling box 6.

[0025] like Figure 1 As shown, a slag outlet 18 is provided on the side wall of the pool body 1 on one side of the partition 15. The direction of the slag outlet 18 is parallel to the chute 2, and a pull-out plate 19 is slidably connected to the inner side of the slag outlet 18. The pull-out plate 19 can fit the pull-out plate 19 to prevent cooling water from leaking out.

[0026] like Figure 2 As shown, a slag inlet 4 is opened on the right side wall of the sliding top cover 3, and a limiting groove 10 is fixedly installed between the inner side walls of the sliding top cover 3, a screw rod 11 is movably installed at the bottom of the limiting groove 10, a support block 12 is threadedly connected to the surface of the screw rod 11, a push plate 13 is fixedly connected to the bottom of the support block 12, a cooling box 6 is fixedly installed on the top of the sliding top cover 3, a heat-absorbing iron plate 7 is fixedly installed on the inner side of the cooling box 6, and the push plate 13 can push the slag to move toward the slag outlet 18.

[0027] like Figure 2 As shown, a separation groove 14 is opened on the left side of the inner bottom of the pool body 1, and the outer wall of the pool body 1 on the left side of the separation groove 14 is connected to a drainage pipe 17. A partition 15 is fixedly installed on the inner wall of the pool body 1 above the separation groove 14, and a plurality of water-permeable holes 16 are evenly opened on the surface of the partition 15. The cooling water in the separation groove 14 can leave along the drainage pipe 17.

[0028] like Figure 2 As shown, baffles 301 are fixedly connected to the left and right sides of the bottom of the sliding top cover 3. The baffles 301 are located on the inner side of the pool body 1 and fit against the inner wall of the pool body 1. The baffles 301 can intercept the two sides of the bottom of the sliding top cover 3, so that the filter residue can continuously absorb water vapor and liquefy.

[0029] like Figure 2 As shown, the upper right side wall of the cooling box 6 is connected to one end of the air intake pipe 5, the other end of the air intake pipe 5 passes through the top of the sliding top cover 3 and is located below the sliding top cover 3, and the lower left side wall of the cooling box 6 is connected to one end of the air outlet pipe 8, the other end of the air outlet pipe 8 passes through the left side wall of the sliding top cover 3 and is located on the inner left side wall of the sliding top cover 3.

[0030] like Figure 2 and Figure 3 As shown, a driving motor 111 is fixedly mounted on the outer side wall of the sliding top cover 3 toward which one end of the screw rod 11 faces, and a rear end of a transmission shaft of the driving motor 111 is fixedly connected to the screw rod 11 .

[0031] In actual use, the sliding top cover 3 slides horizontally on the top of the pool body 1, and is initially located at the rightmost side of the pool body 1, and the slag and cooling water are discharged into the pool body 1 along the slag inlet 4. Under the cover of the left and right baffles 301 at the bottom of the sliding top cover 3, the filter residue and cooling water are temporarily located on the right side of the pool body 1. In the process of the sliding top cover 3 sliding to the left, the filter residue and cooling water are driven to move to the left together by the baffle 301, and the water vapor in the cooling process can be liquefied through the cooling box 6, the air inlet pipe 5, and the air outlet pipe 8. The water vapor moves upward and enters the cooling box 6 along the air inlet pipe 5. Under the heat absorption of the heat absorbing iron plate 7, the water vapor will turn back into liquid, and move downward through the heat dissipating iron plate and the air outlet pipe 8 and then return to the pool body 1. Because the sliding top cover 3 is always located above the filter residue, the water vapor can be continuously liquefied, which saves water resources while avoiding scalding accidents caused by water vapor leakage. The slag-liquid separation can be completed by the partition 15, the water-permeable holes 16 and the separation groove 14. When the sliding top cover 3 slides to the top of the inner partition 15 of the pool body 1, the slag and cooling water will also arrive there. The cooling water will flow along the water-permeable holes 16 on the surface of the partition 15 to the separation groove 14 below, so that the filtered slag and the cooling water are separated, so that it is more convenient to discharge the slag later. At the same time, the slag can be conveniently discharged by driving the motor 111, the screw rod 11, the push plate 13 and the slag outlet 18. After the slag-liquid separation is completed, the pulling plate 19 is pulled out from the slag outlet 18, and then the driving motor 111 drives the screw rod 11 to rotate after power-on, so that the support block 12 and the push plate 13 push the filtered slag to move to the slag outlet 18, and finally discharged. Since the push plate 13 can cover the slag stacking area, all the slag can be pushed to the slag outlet 18 during the discharge process, avoiding accumulation caused by the four corners, thereby improving the slag discharge efficiency.
