Description
TECHNICAL FIELD
[0001] The utility model relates to coke storage technical field, specifically is a coke silo. BACKGROUND
[0002] Dry quenching enters the coke storage process, because the coke in the silo falls from a great height, without anti-breaking device, the coke in the silo will produce secondary crushing and produce a large amount of coke dust, resulting in the increase of coke powder in finished coke, and the economic benefit is poor. The existing dry quenching storage anti-breaking technology mainly adds a buffer device to prevent coke from falling and breaking in the silo to solve the problem of dry quenching breaking in the coke silo. The widely used buffer device is a coke chute, which can be divided into an inclined angle coke chute and a spiral coke chute. The chute can effectively reduce the impact force when the dry quenching falls, but the chute has some defects, such as reducing the space utilization rate of the coke silo, easy to block, and the coke is easy to jump out of the chute and break during falling. SUMMARY
[0003] In order to solve the problem that the coke is easy to collide and break when falling into the coke storage, the utility model provides a coke silo, which contains a buffer net in the coke silo. The coke falls on the buffer net first after entering the coke storage, and then falls through the buffer net. The buffer net reduces the impact, thereby reducing the breakage rate of the coke.

Each buffer net row contains a plurality of buffer nets arranged from left to right with intervals. The buffer nets are connected and fixed to the wall by support pipes.
[0010] In each buffer net row, the plurality of buffer nets are parallel to each other.
[0011] In the two adjacent buffer net rows, the lower end of the buffer net of the upper buffer net row is connected with the upper end of the buffer net of the lower buffer net row one by one.
[0012] The buffer net comprises warp net belts and weft net belts, the warp net belts and the weft net belts are perpendicular, the warp net belts and the weft net belts are high molecular fiber woven belts, and the inner surface of the cone section is provided with an elastic buffer lining plate.
[0013] The coke silo further comprises a discharging chute, the discharging chute is located above the wall of the silo, the discharging chute comprises a vertical pipe section and an inclined pipe section connected in sequence, the discharging chute is connected with a rotary driving mechanism, and the rotary driving mechanism can drive the discharging chute to rotate around the axis of the vertical pipe section.
[0014] The discharging chute is further connected with an angle adjusting mechanism, the vertical pipe section and the inclined pipe section are hinged, and the angle adjusting mechanism can adjust the included angle between the vertical pipe section and the inclined pipe section.
[0015] The beneficial effects of the present application are as follows:

[0035] The coke silo contains the buffer net 3, the coke falls on the buffer net 3 after entering the bunker space 2 of the coke silo, is caught by the buffer net 3, then falls through the mesh hole 33 of the buffer net 3, the impact is reduced by the buffer net 3, so that the breakage rate of the coke is reduced.
[0036] As shown in the figure, Figures 1 to 2 The wall 1 is a vertical cylindrical structure, the axis of the wall 1 is in vertical state, the wall 1 contains a straight cylinder section 11 and a conical cylinder section 12 connected in sequence, and the axes of the wall 1, the straight cylinder section 11 and the conical cylinder section 12 coincide. The outer contour of the buffer net 3 matches the cross section of the wall 1, and the outer contour of the buffer net 3 and the cross section of the wall 1 are both circular.
[0037] Each buffer net 3 is in horizontal state, and a plurality of buffer nets 3 are arranged in uniform and spaced layers in sequence from top to bottom. The buffer net 3 is connected and fixed with the wall 1 through a connecting piece, the connecting piece can adopt a hook, and a plurality of connecting pieces are arranged in uniform and spaced sequence along the circumference of the wall 1.
[0038] As shown in the figure, Figure 2 The buffer net 3 is a warp-weft woven structure, the buffer net 3 contains a warp net band 31 and a weft net band 32, the warp net band 31 and the weft net band 32 are perpendicular, the warp net band 31 and the weft net band 32 have good flexibility, the warp net band 31 and the weft net band 32 are existing high molecular fiber woven bands, for example, the warp net band 31 and the weft net band 32 can both adopt nylon bands or nylon packing bands. The width of the warp net band 31 and the weft net band 32 can be determined according to actual needs or limited experiments.
[0039] In order to ensure that the material can contact the buffer net 3, preferably, the mesh holes 33 of the two buffer nets 3 adjacent in sequence are staggered, that is, the center of the mesh hole 33 of the upper buffer net 3 is vertically opposite to the intersection point of the warp net band 31 and the weft net band 32 of the lower buffer net 3.
[0040] In order to further prevent the material (such as dry quenching coke) from breaking, the inner surface of the conical cylinder section 12 is provided with an elastic buffer lining plate 5, the elastic buffer lining plate 5 and the conical cylinder section 12 are connected in sequence, and the material of the elastic buffer lining plate 5 can adopt a material with strong toughness and wear resistance, such as a silica gel pad.
[0041] The coke silo further comprises a discharging spout 6, which is located above the wall 1 and comprises a vertical pipe section 61 and an inclined pipe section 62 connected in series, and the discharging spout 6 is connected with a rotary driving mechanism capable of driving the discharging spout 6 to rotate around the axis of the vertical pipe section 61.
[0042] The discharging spout 6 can be connected and fixed with the wall 1 through a mounting bracket, the upper end of the wall 1 is an inlet end, the lower end of the wall 1 is an outlet end, and the axis of the wall 1 coincides with the axis of the vertical pipe section 61. The material can enter the silo space 2 of the wall 1 through the discharging spout 6. The rotary driving mechanism can be a motor, which is connected with the vertical pipe section 61 of the discharging spout 6 through a transmission mechanism and is connected and fixed with the mounting bracket. The transmission mechanism can adopt an existing gear transmission mechanism, chain transmission mechanism or belt transmission mechanism.
[0043] As shown in Figure 3 The discharging spout 6 is further connected with an angle adjusting mechanism, the vertical pipe section 61 and the inclined pipe section 62 are hinged through a hinge shaft 63, and the angle adjusting mechanism can adjust the included angle between the vertical pipe section 61 and the inclined pipe section 62. For example, the angle adjusting mechanism can be a telescopic rod 64 (such as a hydraulic cylinder), the two ends of which are hinged with the vertical pipe section 61 and the inclined pipe section 62, respectively.
[0044] The rotary driving mechanism can drive the discharging spout 6 to rotate around the axis of the vertical pipe section 61, and the angle adjusting mechanism can adjust the included angle between the vertical pipe section 61 and the inclined pipe section 62. Thus, multi-point distribution can be performed in the silo space 2, and the distribution of the material is more uniform.
[0045] The working process of the coke silo (which can also be referred to as a dry quenching storage silo) will be introduced below.
[0046] When the finished dry quenched coke (material) is transported to the coke silo for storage, it first enters the silo space 2 through the discharging spout 6, and the discharging spout 6 has the function of rotary distribution. After the dry quenched coke enters the silo space 2, it first performs free fall motion. Since the silo space 2 is arranged with multiple layers of elastic buffer nets 3, the dry quenched coke successively contacts each layer of the buffer nets 3 during the falling process and passes through the mesh holes 33 of the buffer nets 3, and the impact force is absorbed by the mesh belt of the buffer nets 3, and thus the falling speed is controlled. Since the buffer nets cover the entire horizontal cross section of the silo, the material falling from any position in the silo can fall onto the buffer nets, thereby reducing the breakage rate.
[0047] In addition, an elastic buffer lining plate 5 is arranged on the inner wall of the bottom of the coke silo. The dry quenched coke still has a certain speed after passing through the buffer nets 3, and the elastic buffer lining plate 5 can serve as the last line of defense to absorb the impact force of the falling coke, so that the coke falls gently in the coke silo for storage, thereby better preventing the dry quenched coke from being broken.
