Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of raw coal coking cooling, in particular to a special base in a coke quencher of a small coke oven. Background Art
[0002] In the chemical metallurgical process, coking in a small coke oven is one of the important indicators for judging the quality of purchased raw coal. After coking is completed, the high-temperature coke needs to be cooled. The traditional cooling method is to place the coke box on a bracket in front of the drain outlet inside the quencher, close the quencher door, and cool it by spraying water from the top. After the coke in the coke box is completely submerged in cooling water, the excess water will overflow to the outside of the coke box and enter the quencher. The bottom surface of the quencher is a slope inclined toward the drain outlet. The water flows toward the drain outlet under the action of gravity on the internal slope of the quencher, and is finally discharged through the drain outlet with a filter at the rear. However, the existing technology has the following problems:
[0003] The coke temperature is high and the water spraying rate is large. The large amount of iron oxide scale produced when the coke is cooled by water spraying can easily be washed to the drain outlet below the slope by the flowing water and block the filter, causing water to overflow from the drain outlet to the door of the quencher, and then overflow from the gap of the door of the quencher to the ground in the room, affecting the safe use of other live equipment in the room.
[0004] Existing coke box bracket in the coke quencher (such as Figure 5 The height of the forklift is relatively low, and the forklift currently used is thicker than the normal forklift. As a result, after the coking box is placed on the bracket, the forklift's fork will be stuck between the bottom plate of the coking box and the internal bracket and cannot be withdrawn normally. The coking box needs to be supported by tools before the forklift can be withdrawn, which poses a safety risk during operation. Utility Model Content
[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a special base in a small coke oven quencher, which solves the problem of cooling water overflowing the quencher and the transportation and placement of the coking box by combining a raised bracket with a water tray with a filter.
[0006] To achieve the above-mentioned purpose, the present invention provides a special base for a small coke oven quencher. The quencher has a water outlet. After the raw coal is coked, the coke box is placed in the quencher by a forklift for top water spray cooling. Iron oxide scale is generated during the process. The special base for the small coke oven quencher comprises:
[0007] A water tray is provided at the center of the coke quencher. The water tray is larger than the coking box and is used to collect cooling water and iron oxide scale.
[0008] A raised bracket is provided at the center of the water tray, wherein the size of the raised bracket is smaller than the coking box and is used to support the coking box;
[0009] The overflow port is located on the upper edge of the rear end of the water tray, with slots at both ends;
[0010] A filter screen is provided at the overflow outlet, and the filter screen is installed at the overflow outlet position through the slot;
[0011] The lower edge of the filter is not higher than the upper edge of the front end of the water tray. The inner bottom surface of the quencher is a slope inclined toward the drain outlet. After the dedicated base is tilted, the lower edge of the filter is lower than the upper edge of the front end of the water tray, so that part of the cooling water can be filtered out through the filter. Since the slope of the slope drainage is small, the movement of the dedicated base can be restricted by its own weight.
[0012] Furthermore, it also includes:
[0013] Four pulleys are arranged at the four corners of the bottom of the water tray and are used to move the base. The four pulleys are provided with anti-slip damping and need to be manually pulled and pushed to move.
[0014] Furthermore, it also includes:
[0015] The handrail is arranged at the front end of the water tray and cooperates with the pulley to lift the base and pull out the base to clean the oxidized iron scale.
[0016] Furthermore, the height of the raised bracket is higher than the water tray, so that the fork of a forklift can move in and out.
[0017] Furthermore, the height difference between the front end of the water tray and the bottom of the coking box is 120 mm, and the coking box is placed on the upper surface of the raised bracket, so the bottom of the coking box and the upper surface of the raised bracket are at the same height.
[0018] Furthermore, the size of the raised bracket is smaller than the coking box. After the coking box is placed on the upper surface of the raised bracket, a width of 70 mm is left on both sides for the fork to enter and exit and place the coking box.
[0019] Furthermore, the filter is made of 304 stainless steel.
[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] (1) The utility model provides an overflow outlet with a filter at the upper edge of one end of the water tray. Iron oxide scale is deposited at the bottom of the water tray, thus avoiding clogging of the filter above and ensuring smooth drainage. Water can be discharged from the drain outlet of the quencher without being blocked by iron oxide scale, thereby preventing cooling water from overflowing from the quencher door and affecting the safe use of other live electrical equipment in the room.
[0022] (2) The utility model uses a combination of a raised bracket and a water tray to enable the forklift's shovel to move in and out smoothly, eliminating the risk of the shovel getting stuck and improving the safety and efficiency of the operation.
[0023] (3) The base of the utility model is equipped with pulleys and handrails, which makes it easy to lift the base for drainage, and also facilitates the movement of the base and the cleaning of iron oxide, thereby improving working conditions and reducing labor intensity.
[0024] In summary, the utility model effectively solves the problems of cooling water overflow and inconvenient transportation and placement of coking boxes in the traditional coke quenching process, and improves the safety and operational convenience of the coke quenching process.

[0034] like Figure 1-Figure 4 As shown, this embodiment provides a dedicated base for a small coke oven quencher. The quencher 1 has a drain port 2. After the raw coal is coked, the coke box is placed in the quencher by a forklift for top water spray cooling. During this process, iron oxide scale is generated. The dedicated base for the small coke oven quencher includes:
[0035] The water tray 4 is located in the center of the coke quencher 1 and is used to collect iron oxide scale;
[0036] A raised bracket 5 is provided at the center of the water tray 4 and is used to support the coking box;
[0037] The overflow port 6 is provided on the upper edge of the rear end of the water receiving tray 4, and slots 8 are provided at both ends thereof;
[0038] The filter screen 7 is provided at the overflow port 6 and is installed at the overflow port 6 through the slot 8. The filter screen 7 is detachable and can be inserted into the slot to facilitate quick replacement of the filter screen after damage.
[0039] The lower edge of the filter screen 7 is not higher than the upper edge of the front end of the water tray 4. The bottom surface of the interior of the coke quencher is a slope inclined toward the drain outlet. The dedicated base is placed behind the coke quencher. The lower edge of the filter screen is lower than the upper edge of the front end of the water tray. Since the slope of the slope drainage is small, the dedicated base can limit the movement by its own weight. After the inclined placement, the lower edge of the filter screen 7 is lower than the upper edge of the front end of the water tray 4, so that part of the cooling water is filtered by the filter screen 7 to intercept the iron oxide scale and then flow out and be discharged through the drain outlet 2.
[0040] Specifically, the dedicated base of the small coke oven quencher 1 also includes four pulleys 9, which are arranged at the four corners of the bottom of the water tray 4 and are used to move the base. Each pulley is equipped with a damping brake, which can provide a stable anti-slip effect in a non-moving state. This means that only when manual push and pull are applied to the dedicated base, the pulley 9 will be unlocked and the dedicated base will be allowed to move.
[0041] Furthermore, the special base in the small coke oven quencher also includes an armrest 10, which is provided at the front end of the water tray 4 and cooperates with the pulley 9 to facilitate the placement of the base into the quencher 1. After the quenching is completed and the coking box is taken out, it is convenient to lift the base to discharge the remaining cooling water and pull out the base to clean the iron oxide scale.
[0042] Specifically, the height of the raised bracket 5 is higher than the water tray 4, and there is enough space for the fork of the forklift to enter and exit without getting stuck.
[0043] Preferably, the height difference between the front end of the water tray 4 and the bottom of the coking box is 120 mm, which is much greater than the thickness of the fork.
[0044] Furthermore, after the coking box is placed on the upper surface of the raised bracket 5, space is left on both sides for the fork to enter and exit and for the coking box to be placed.
[0045] Furthermore, the filter screen 7 is made of 304 stainless steel.
[0046] Specifically, the filter pore diameter of the filter screen 7 is 5 mm.
[0047] After deducting the volume occupied by the central raised bracket 5 from the total volume of the water pan 4, the maximum water volume that can be held in the coke quencher 1 is about 24L. The national standard for small coke oven coking stipulates that the water consumption for quenching shall not exceed 15kg, or 15L. Therefore, when water is sprayed, the volume of the water pan 4 is larger than the spraying volume, and the water will not overflow into the coke quencher 1. Only a small amount of water will splash out, which can be discharged through the drain outlet 2 on its own.
[0048] When in use, first replace the filter screen 7 through the slot 8, and put the special base in the small coke oven quencher into the center of the quencher 1 to replace the filter screen 7. Figure 5The coke box is placed on the raised bracket 5 using a forklift. Because the raised bracket 5 is higher than the water pan 4, the bottom of the coke box is 120 mm higher than the front upper edge of the water pan 4, leaving ample space for the forklift's forks to enter and exit without getting stuck. The door of the coke quencher 1 is then closed, and water is sprayed from the top to cool the coke. After the cooling water completely submerges the coke inside the coke box, excess water overflows out of the coke box and into the water pan 4. During quenching, since the overflow port 6 is at the top, the iron oxide scale produced by the water cooling of the coke box settles at the bottom of the water pan and does not block the filter screen 7 above. Since the dedicated base of the small coke oven quencher is tilted, the bottom edge of the filter screen 7 is lower than the front upper edge of the water pan 4. Therefore, some cooling water is filtered through the filter screen 7 and flows into the coke quencher 1, and finally discharged from the drain port 2 with a filter at the rear of the coke quencher 1. After the quenching is completed, the front end of the entire base is lifted by the handrail 10, and the remaining cooling water flows out through the filter screen 7, filtering out the iron oxide scale. Finally, the base is pulled out and the iron oxide scale is cleaned. In this way, the iron oxide scale is collected in a centralized manner and will not block the drain port 2 of the quencher 1, causing the cooling water to accumulate in the quencher 1 and overflow from the gap in the door of the quencher 1.
[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
