Description

Technical Field

[0001] The utility model belongs to the field of top-loading coke ovens in coal chemical industry, and specifically relates to a coal distributor for supporting coal in a coal hopper of a coal charging vehicle, a coal hopper of a coal charging vehicle comprising the coal distributor, and a top-loading coke oven coal charging vehicle comprising the coal hopper. Background Art

[0002] Top-loading coke oven equipment is a coke oven equipment in which the coking coal is loaded from the top of the furnace into the carbonization chamber. Its supporting devices usually include coal loading cars and coal towers. Among them, the coal loading car works on the top of the coke oven and is a special movable vehicle for loading coal into the coke oven carbonization chamber; and the coal tower is used to store the coking coal so that coal can be added to the coal loading car. It is usually also arranged on the top of the coke oven, and the coal loading car can pass through the bottom of the coal tower. The coke oven carbonization chamber is a closed chamber structure composed of the machine side furnace door, the coke side furnace door, the furnace cover of the coal loading hole on the furnace top and the raw coal gas extraction system. The combustion chambers arranged on both sides thereof are used to strengthen the heating for high-temperature carbonization of the coking coal, and the high-temperature flue gas generated is extracted by the raw coal gas extraction system. The coke oven carbonization chamber is a closed structure composed of steel columns, protective plates, furnace door frames, furnace doors and coal loading port cover, so that the mixed coal loaded by the coal loading car will not overflow, to ensure that the mixed coal in the carbonization chamber is full, level and not blocked, and leave a furnace top space that is conducive to the rapid discharge of high-temperature flue gas, to ensure that there is no smoke around the furnace door, furnace door frame and coal loading port cover after coal loading, to prevent environmental pollution, thereby preventing fire due to poor sealing from burning the furnace protection equipment, causing the coke oven to lose protective pressure and shortening the service life of the coke oven.

[0003] The coking process of coke oven is a continuous and repeated cyclic production process. Since the coal loading car is in the high temperature area of ​​the coke oven top and the coal hopper is the main equipment of the coal loading car, the four coal hoppers of the coal loading car take coal from the coal tower leak in a continuous cycle, and then continuously cycle the coal loading operation into the coke oven carbonization chamber. This operation mode leads to the long-term cycle operation of the coal hopper of the coal loading car, and the coal loading car has to operate according to the coal loading plan every 12 minutes, that is, the coal hopper of the coal loading car has to run twice every 12 minutes, and the coal loading time for each furnace is about 4 minutes. As a result, when the coal loading car takes coal from the coal tower leak into the coal hopper, the impact force on the coal material at the bottom is different due to gravity. The coal material at the bottom of the coal hopper will be compacted, causing the load of the coal loading screw to increase, stop running or reduce the speed, affecting the automatic operation and operation of the equipment. At the same time, in order to respond to production emergencies, the coal loader driver will manually knock on the coal hopper to vibrate the coal down when taking special operations, or the operator will climb to the top of the coal hopper and poke the coal with a long pick. This not only increases unnecessary labor costs, labor intensity and safety risks, but also causes production operations to stop, affecting the smooth production of the coking process.

[0036] The first aspect of the utility model provides a coal distributor for supporting coal in a coal hopper of a coal loading vehicle, such as Figure 1 As shown, the coal distributor is cross-shaped, including a transverse member 10 and a longitudinal member 20. The longitudinal member 20 is arranged perpendicular to the transverse member 10, and the two are combined to form a cross-shaped configuration. The transverse member 10 includes a first plate 11 and a second plate 12, both of which are longitudinal plates, and the two are connected at a certain angle so that the transverse member 10 has a ∧-shaped cross section. The first plate 11 and the second plate 12 respectively form the two sides of the ∧-shaped structure of the transverse member 10. The longitudinal member 20 includes a third plate 21 and a fourth plate 22, both of which are longitudinal plates, and the two are connected at a certain angle so that the longitudinal member 20 has a ∧-shaped cross section. The third plate 21 and the fourth plate 22 respectively form the two sides of the ∧-shaped structure of the longitudinal member 20. The two sides of the transverse member 10 formed by the first plate 11 and the second plate 12 and the two sides of the longitudinal member formed by the third plate 21 and the fourth plate 22 can receive and guide the coal to slide down, disperse the impact force of the coal falling, and prevent the falling coal from being over-compressed. The cross-shaped configuration formed by the transverse member 10 and the longitudinal member 20 is conducive to reducing the impact force when taking coal, and will not bring too much resistance to coal taking and thus affect the coal taking efficiency.

[0037] In some embodiments, in the installed state, at least one of the first plate 11 and the second plate 12 is inclined relative to the vertical direction. Preferably, both the first plate 11 and the second plate 12 are inclined relative to the vertical direction, so that both sides of the cross member 10 can be used to receive and guide the coal to slide down, disperse the impact force of the falling coal, and maximize the effect of dispersing the impact force.

[0038] Similarly, in some embodiments, in the installed state, at least one of the third plate 21 and the fourth plate 22 is inclined relative to the vertical direction. Preferably, the third plate 21 and the fourth plate 12 are both inclined relative to the vertical direction, so that both sides of the longitudinal member 20 can be used to receive and guide the coal to slide down, disperse the impact force of the falling coal, and maximize the effect of dispersing the impact force.

[0039] In some embodiments, in the installed state, the first plate 11 and the second plate 12 are symmetrically arranged, that is, the first plate 11 and the second plate 12 are axially symmetrically distributed with respect to a vertical plane therebetween.

[0040] Similarly, in some embodiments, in the installed state, the third plate 21 and the fourth plate 22 are symmetrically arranged, that is, the third plate 21 and the fourth plate 22 are axially symmetrically distributed relative to the vertical plane therebetween. Such an arrangement is conducive to balanced force, preventing one side from being subjected to large force and the other side from being subjected to small force, thereby shortening the life of the coal distributor.

[0041] In some embodiments, preferably, the angle between the first plate 11 and the second plate 12 is 30 to 120 degrees, so as to achieve a better coal separation effect. A too large angle will affect the coal loading efficiency, and a too small angle will have a limited effect on dispersing the impact force. More preferably, the angle between the first plate 11 and the second plate 12 is 60 degrees.

[0042] Similarly, in some embodiments, preferably, the angle between the third plate 21 and the fourth plate 22 is 30 to 120 degrees to achieve a better coal separation effect. Too large an angle will affect the coal loading efficiency, and too small an angle will have limited effect in dispersing the impact force.

[0043] In some embodiments, one or more reinforcing ribs are connected between the first plate 11 and the second plate 12 so that the cross member 10 has an A-shaped cross section. Providing the reinforcing ribs helps to increase the strength and rigidity of the coal distributor, thereby enhancing its bearing capacity and anti-deformation ability. For example, a plurality of reinforcing ribs can be spaced apart from each other along the longitudinal length of the first plate 11 and the second plate 12, or a plurality of reinforcing ribs can be spaced apart from each other along the height direction of the first plate 11 and the second plate 12.

[0044] Similarly, in some embodiments, one or more reinforcing ribs are connected between the third plate 21 and the fourth plate 22 so that the longitudinal member 20 has an A-shaped cross section. Providing reinforcing ribs helps to increase the strength and rigidity of the coal distributor, thereby enhancing its bearing capacity and anti-deformation ability.

[0045] In some embodiments, Figure 2 As shown, the longitudinal member 20 includes a first longitudinal member 23 and a second longitudinal member 24, the first longitudinal member 23 and the second longitudinal member 24 are respectively connected to both sides of the transverse member 10, the end of the first longitudinal member 23 is connected to the first plate 11, and the end of the second longitudinal member 24 is connected to the second plate 12. Providing the longitudinal member 20 as a two-piece structure is conducive to simplifying the structure of the coal distributor and facilitating its assembly.

[0046] In some embodiments, the first longitudinal member 23 and the second longitudinal member 24 are connected to the middle of the transverse member 10, which is conducive to better coal distribution.

[0047] The second aspect of the utility model provides a coal hopper for a coal loading vehicle, such as Figure 3 As shown, the coal hopper includes a coal hopper body 1 and a coal distributor 2 as described in the first aspect of the utility model arranged inside the coal hopper body 1. Due to the coal distributor 2 as described in the first aspect of the utility model, the coal hopper has all the advantages corresponding to those described in the first aspect of the utility model, which will not be repeated here.

[0048] In some embodiments, the ends of the coal separator 2 (i.e., the two ends of the transverse member 10 and the two ends of the longitudinal member 20) are connected to the inner wall of the coal hopper body 1, and additionally, the upper side of the coal separator 2 is fixed to the crossbeam of the coal hopper body 1 through a hanger so as to enhance the ability of the coal hopper to withstand impact force.

[0049] In some embodiments, the coal hopper further includes a screw feeder (not shown in the figure) disposed below the coal hopper body 1. The coal distributor 2 is disposed at a certain distance above the screw feeder to reduce the impact force of the coal before it falls into the screw feeder, to prevent the coal from falling directly onto the screw feeder, and to reduce the friction and accumulated pressure between the coal and the rotary vane and the inner wall of the coal hopper.

[0050] The third aspect of the utility model provides a top-loading coke oven coal-charging car, which includes the coal hopper described in the second aspect of the utility model. Due to the coal hopper described in the second aspect of the utility model, the coal-charging car has all the advantages described in the second aspect of the utility model, which will not be repeated here.

[0051] Due to the above-mentioned cross-shaped coal divider, the coal hopper provided in the second aspect of the utility model and the coal loading car provided in the third aspect of the utility model can achieve the purpose of quickly loading coal after the coal loading car takes coal, and can solve the problems of the coal loading screw being overloaded and unable to operate automatically after the coal loading car takes coal, and the inability to achieve fast coal loading operation and stop coke oven production operation. It can improve production efficiency, ensure the continuity and stability of production operations, and avoid production failures that cannot quickly carry out coal loading operations and process accidents that stop coke oven production operations during the production process.

[0052] Example

[0053] Take JNX3-70-1 coke oven as an example:

[0054] The utility model provides a coal distributor for supporting coal in the coal hopper of a coal loading car, which has a better effect when installed and used in a JNX3-70-1 type coke oven coal loading car. The +-shaped coal distributor installed in the coal hopper disperses the impact force of coal when the coal hopper takes coal.

[0055] The +-shaped coal distributor is made of steel plates, steel bars and other components. The specific dimensions are as follows:

[0056] (1) Prepare steel plate: the total length of the steel plate is 34000 mm, the width is 220 mm, and the thickness is 16 mm.

[0057] (2) The steel plates are made into plates of specific sizes: plates with a length of 2200 mm (4 pieces) and plates with a length of 1000 mm (8 pieces).

[0058] (3) Prepare steel bars: length 5000 mm, diameter 16 mm.

[0059] (4) Grind the upper surface (thickness) of the plate into a 45-degree slope, then weld the grinded surfaces of two plates of the same length together to form a ∧ shape. At the same time, weld steel bars in the ∧-shaped groove (3 steel bars are welded in each section, and welding is performed intermittently) to play the role of reinforcing rib support to form an А shape with an opening diameter of 200 mm below the А shape.

[0060] The installation method of the +-shaped coal distributor is as follows:

[0061] (1) Empty the coal in the coal hopper of the coal loading truck.

[0062] (2) Open the side baffle of the coal hopper of the coal loading car.

[0063] (3) First install and weld an A-shaped bar with a diameter of 2200 mm as a transverse member.

[0064] (4) Weld an A-shaped bar with a diameter of 1000 mm to the left side of the middle of the previously installed and welded A-shaped bar as the first longitudinal member.

[0065] (5) Weld another A-shaped bar with a diameter of 1000 mm to the right side of the middle of the A-shaped bar as the second longitudinal member, so that the A-shaped bars on the left and right sides are in a straight line. In this way, the +-shaped coal divider is completed.

[0066] During the application process, the +-shaped coal divider can be welded in the four coal hoppers of the coal loading car according to the above method. This is conducive to reducing the impact force of the natural falling of coal materials during the coal loading process of the coal loading car, so as to achieve the effect of rapid coal loading and loading. Specifically, the +-shaped coal divider disperses the impact force of the coal tower leaking mouth during the coal loading process of the coal loading car, solves the problem of the spiral stopping or not being able to rotate quickly after the coal loading car takes coal and the continuous production operation of the coke oven, and can directly realize the rapid coal loading after the coal loading car takes coal, avoiding production failures that cannot be quickly loaded during the production process and process accidents that stop the coke oven production operation. Normal coal loading can improve production efficiency and ensure the continuity and stability of production operations. Moreover, the +-shaped coal divider is easy to operate, the operation implementation process is simple, the investment cost is very low, and the implementation effect is good, which is conducive to rapid coal loading and improving the production efficiency of the coke oven.

[0067] Finally, it should be noted that the embodiments described above are only some embodiments of the utility model, not all embodiments. The detailed description of the embodiments of the utility model is not intended to limit the scope of the utility model claimed for protection, but only represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
