Description

Technical Field

[0001] The utility model belongs to the technical field related to zinc roasted sand preparation, in particular to a water quenching tool for a byproduct of zinc roasted sand calcination. Background Art

[0002] Zinc roasted sand is the product obtained after the zinc concentrate is roasted. It is a brown micro-granular solid. It is an intermediate product and a raw material for the production of direct zinc oxide, electrolytic zinc, electric furnace zinc powder, etc. For the production of zinc roasted sand, many are prepared using zinc-containing waste slag (waste slag produced during zinc smelting). The production process includes the pretreatment of waste slag, the preparation of mixed materials, and the calcination of mixed materials to produce slag. For slag, it is usually cooled quickly by water quenching to form water slag or kiln slag, thereby forming building materials. It can also be further ground and used as a raw material for cement and ceramic tiles. However, there are still the following disadvantages in the actual water quenching process:

[0003] When the byproduct (slag) produced after the calcination of zinc roasted sand raw materials is water quenched, it is mostly directly put into the water quenching pool and quickly cooled by a large amount of cooling water. Because the slag is high-temperature slag when it is just produced, if it is directly slowly cooled, it will solidify into a large solid substance; after water quenching, due to the rapid cooling, the slag is rapidly cooled and broken down into small particles of slag, which can be directly used as building materials without crushing. However, if it is directly put into the water quenching pool, the slag will produce small particles of slag, which is difficult to salvage, and it is not convenient to process the next batch;

[0004] During the water quenching of slag byproducts, a large amount of heat is absorbed by the cooling water. However, if the processing frequency is too high, the temperature of the cooling water will gradually rise. Therefore, it is necessary to ensure that the heat absorbed by the cooling water is dissipated in a timely and rapid manner. The conventional method can only be cooled naturally, and there is no way to accelerate cooling.

[0005] Slag is usually put directly into the water quenching pool at high temperature. At this time, the high temperature is likely to cause splashing when feeding. The splashed water or slag may carry high temperature and cause certain cooling to the surrounding environment or workers. Therefore, certain pre-cooling treatment should be carried out before feeding. Utility Model Content

[0014] Furthermore, a symmetrically distributed lifting lug is fixed on one side of the frame close to the ramp block, a slot is provided at the bottom of the frame, and the slot passes through the front side of the frame, and a through slot is vertically provided at the center of the bottom of the frame, the through slot is connected to the slot, and a plug board is inserted in the slot.

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] See also Figure 1-9 As shown, the utility model is a water quenching tool for byproducts of zinc roasted sand calcination, comprising a water quenching pool 1, a water quenching basket 2, a slag guide slide 3, a paving box 4 and a column 5; a slope block 101 is fixed inside the water quenching pool 1, and a water quenching basket 2 is also movably arranged in the water quenching pool 1 beside the slope block 101, and a heat-conducting copper plate 103 is arranged in the water quenching pool 1 outside the water quenching basket 2, and a heat-conducting copper plate 103 is fixed on a side away from the water quenching basket 2 with a heat dissipation fin 1031 penetrating and extending out of the side of the water quenching pool 1;

[0035] A large amount of cooling water is injected into the water quenching pool 1. If the cooling water is insufficient, the slope block 101 can be changed to a frame 201 structure, and only the guide groove 1011 needs to be retained. A water quenching basket 2 is set in the water quenching pool 1, and high-temperature slag is directly put into the water quenching basket 2. Then, even if the slag after water quenching is broken, it will not be scattered in the water quenching pool 1, but will be concentrated in the water quenching basket 2, which is more convenient for material removal operation; a heat-conducting copper plate 103 is set in the water quenching pool 1 to conduct the heat of the cooling water and dissipate it to the external environment through the heat dissipation fins 1031, thereby increasing the heat dissipation effect and facilitating continuous operation;

[0036] A paving box 4 is fixed at one end of the water quenching tank 1, a material box 401 is fixed at the upper end of the paving box 4, a column 5 is fixed at the side of the paving box 4 away from the water quenching tank 1, two bearing seats 502 are fixed at the upper end of the column 5, and a rope winding roller 503 is rotatably connected between the two bearing seats 502;

[0037] The water quenching basket 2 includes a frame 201, and filter screens 205 are fixed on the four sides of the frame 201; the spreading box 4 is used to spread the slag after water quenching. The slag is temporarily stored in the water quenching basket 2 after water quenching. The rotation of the rope roller 503 drives the traction rope 504 to pull the water quenching basket 2, so that it moves along the slope block 101 until it stops at the highest point of the slope block 101. At this time, the water quenching basket 2 is inclined, and the excess cooling water is filtered out from the filter screen 205 on the side of the frame 201. Finally, the water quenching basket 2 is pulled onto the discharge box 401 to guide the slag in the water quenching basket 2 into the spreading box 4.

[0038] A water pump 102 is fixed to one end of the water quenching tank 1 away from the paving box 4, a water pumping pipe 1021 is fixed to the water pumping end of the water pump 102, and the water pumping pipe 1021 penetrates the lower part of the water quenching tank 1 and penetrates into the water quenching tank 1, a water outlet pipe 1022 is fixed to the water outlet end of the water pump 102, and the water outlet of the water outlet pipe 1022 faces above the water quenching basket 2;

[0039] The water pump 102 draws cooling water from the water quenching pool 1 through the water pumping pipe 1021, sprays it out from the water outlet pipe 1022, and guides it to the top of the water quenching basket 2 and toward the outlet of the slag guide chute 3. Firstly, it increases the fluidity of the cooling water, forms a circulation, and accelerates the heat dissipation. Secondly, it timely impacts the water cooling on the discharged high-temperature slag to increase the pre-cooling treatment function.

[0040] An inclined slag guide chute 3 is arranged above one side of the water quenching tank 1. Two clamping blocks 302 are fixed at the bottom of the slag guide chute 3. The lower clamping block 302 is clamped on the side of the water quenching tank 1. Enclosures 301 are fixed on both long sides of the inclined surface of the slag guide chute 3.

[0041] The higher end of the slag guide chute 3 is connected to the slag storage device and is protected by a surrounding plate 301 to prevent the slag from sliding during the guide process, and the slag is directly guided into the water quenching basket 2 in the water quenching tank 1.

[0042] Two groups of rollers 203 are symmetrically arranged at the bottom of the frame 201, and the inner bottom surface of the water quenching tank 1 is provided with symmetrically distributed guide grooves 104, and the rollers 203 are placed in the corresponding guide grooves 104. The upper inclined surface of the ramp block 101 is also provided with a guide groove 1011 connected to the guide groove 104, and the lower end of the ramp block 101 is closer to the water quenching basket 2, and the higher end of the ramp block 101 is flush with the upper end of the water quenching tank 1;

[0043] During the movement of the water quenching basket 2, it moves along the guide groove 2 104 and the guide groove 1 1011 to avoid deviation during the movement. The water quenching basket 2 is pulled and guided to the slope block 101, stops at the top of the slope block 101, and starts to drain water. After draining water for a period of time, it moves to the top of the discharge box 401.

[0044] A symmetrically distributed lifting lug 202 is fixed on one side of the frame 201 close to the ramp block 101. A slot 2011 is provided at the bottom of the frame 201, and the slot 2011 passes through the front side of the frame 201. A through slot 2012 is vertically provided at the center of the bottom of the frame 201. The through slot 2012 is connected to the slot 2011, and a plugboard 204 is inserted into the slot 2011.

[0045] A reduction motor 501 is also fixed to the upper end of the column 5, and the output shaft of the reduction motor 501 is fixedly connected to one end of a rope winding roller 503, and a traction rope 504 is wound around the rope winding roller 503, and one end of the traction rope 504 extends out and is connected to the lifting lug 202;

[0046] The reduction motor 501 is used to drive the rope winding roller 503 to rotate, thereby driving the traction rope 504 to be wound. Because the traction rope 504 is connected to the lifting lugs 202 (the number of lifting lugs 202 can be increased, and the traction rope 504 can be increased with branches to ensure greater stability), the water quenching basket 2 is pulled toward the column 5. After the water quenching basket 2 moves to the discharge box 401, the plug plate 204 is pulled out, and the slag in the water quenching basket 2 is discharged through the through groove 2012 and introduced into the paving box 4 through the discharge chute 402 for paving.

[0047] The bottom of the material box 401 is a through-opening arrangement, a material chute 402 is through-opened on the top of the material box 401, a U-shaped limit frame 403 is fixed on the top of the material box 401 outside the material chute 402, and the opening of the limit frame 403 faces the water quenching tank 1, and the paving box 4 and the water quenching tank 1 are vertically and horizontally distributed at right angles in a top view;

[0048] The limiting frame 403 effectively prevents the water quenching basket 2 from excessive displacement, so that it does not slide on the material box 401.

[0049] The specific working principle of the utility model is as follows: first, the water quenching basket 2 is placed in the water quenching pool 1, and the higher end of the slag guide chute 3 is connected to the slag storage device, and the enclosure 301 is used for enclosure. The high-temperature slag is introduced into the water quenching basket 2 in the water quenching pool 1 through the slag guide chute 3. At the same time, the water pump 102 draws cooling water in the water quenching pool 1 through the water pumping pipe 1021, and sprays it from the water outlet pipe 1022, guiding it to the top of the water quenching basket 2 and toward the outlet of the slag guide chute 3, so as to timely impact water cooling the high-temperature slag discharged, thereby increasing the pre-cooling processing function. The slag after water quenching is concentrated in the water quenching basket 2, and the reduction motor 501 is used to drive the rope winding roller 503 to rotate, thereby driving the traction rope 504 to wind, and because the traction rope 5 04 is connected to the lifting ear 202, thereby pulling the water quenching basket 2 toward the column 5; until it stops at the highest point of the slope block 101, at this time the water quenching basket 2 is inclined, and the excess cooling water is filtered out from the filter screen 205 on the side of the frame 201 and flows back into the water quenching pool 1. After a period of time, the traction rope 504 is pulled by the rope roller 503 again to move the water quenching basket 2 to the discharge box 401, and then the plug plate 204 is pulled out, and the slag in the water quenching basket 2 is discharged through the through groove 2012, and introduced into the paving box 4 through the discharge chute 402 for paving. Finally, a heat-conducting copper plate 103 is also arranged in the water quenching pool 1 to conduct the heat of its cooling water and dissipate it to the external environment through the heat dissipation fins 1031, thereby increasing the heat dissipation effect.
