Description

Unpowered windproof and antifreeze device for coal bunker

technical field

The utility model relates to the field of energy transportation, in particular to a non-powered windproof and antifreeze device for coal bunkers, in particular to a non-powered windproof and antifreeze device for coal bunkers capable of preventing wind and keeping warm.

Background technique

In the cold northern regions, antifreeze measures for coal bunkers have always been a headache. Because the product coal has been selected and washed, its water content is relatively high. In winter, the entry of cold wind will make the raw coal easy to freeze into blocks, and the coal blocks will gradually freeze the wet raw coal particles around them to form larger frozen blocks. When the flow moves downward, the larger frozen coal blocks are easy to get stuck in the raw coal bunker and cause blockage; when the blockage time is longer, the frozen coal blocks will continue to freeze the surrounding moist raw coal particles, and finally form a frozen whole at the exit, making the product Coal cannot be loaded smoothly. At present, when frozen coal is blocked at the outlet of the raw coal bunker, holes are generally opened on the outer wall of the raw coal bunker, and the block is broken manually with a steel drill to eliminate the blockage. This method is not only inefficient, but also labor-intensive and takes a long time. Some will place a movable cover plate with wheels on the operation floor, remove the cover plate when loading is required, and place the cover plate on the loading port after loading, so as to isolate the external cold air. This method has a better antifreeze effect, but it needs manual operation. The one is to increase the workload of the workers, and the other is to cause serious consequences if it is forgotten. Chinese utility model patent CN 204210960 discloses an anti-freezing coal device at the outlet of a raw coal bunker, including a raw coal bunker, a hot air injection pipe, a hot air conduit, an air source distributor and a hot air source. The utility model uses the existing hot air source of the coal-fired power plant to inject hot air into the area from the gate door of the raw coal bunker outlet to the inlet pipe section of the coal feeder, which is prone to frozen coal blockage, so that the frozen coal blocks can be thawed quickly and the flow of raw coal particles can be restored. sex. However, special measures are generally not taken at the loading port, which makes the external cold wind enter the operating layer of the warehouse through the loading port, and the problem of antifreeze and heat preservation has not yet been solved.

The unpowered windproof and antifreeze device of the coal bunker is composed of a material chute 1, an antifreeze plate 2, a counterweight 3, a suspension 4, a heat preservation plate 5 and a curved steel plate 6. The material chute 1 is connected with the antifreeze plate 2 rotating shafts, wherein the material chute 1 is made of the first steel plate 11, the second steel plate (not shown in the figure), the third steel plate (not shown in the figure), the fourth steel plate (not shown in the figure) not shown in), the antifreeze plate 2 is composed of two mirror-symmetrical fifth steel plates 21 and sixth steel plates (not shown in the figure), and the two steel plates of the antifreeze plate 2 (i.e. the fifth steel plate 21 and the sixth steel plate, The same below) are respectively connected with the lower edge shafts of a pair of parallel steel plates on the chute 1; such as: the fifth steel plate 21 and the sixth steel plate are connected with the first steel plate 11 and the third steel plate shaft respectively or are respectively connected with the second steel plate and the second steel plate. The fourth steel plate shaft is connected. Specifically, taking the shaft connection between the first steel plate 11 and the fifth steel plate 21 as an example, the two ends of the lower edge of the first steel plate 11 are respectively welded with round steel 15, the weld seam is relatively short, and only the range of 100 mm at both ends is welded, and there is no welding operation in the middle ; The width of the fifth steel plate 21 is consistent with the length of the first steel plate 11, the length of the fifth steel plate 21 is consistent with the length of the second steel plate, the fifth steel plate 21 is welded with a steel pipe 23 parallel to its edge in its center, and the steel pipe 23 is sleeved on the round steel 15 On, the rotation of steel pipe 23 can drive the activity of antifreeze plate 2, for guaranteeing that steel pipe 23 rotates around round steel 15 flexibly, steel pipe 23 internal diameters are bigger than round steel 15 diameters. The steel pipe 23 is connected with an arc-shaped steel plate 6 made by bending. Its main function is to protect the cleanliness of the round steel 15 and the steel pipe 23, and prevent materials from entering the gap between the round steel 15 and the steel pipe 23 to cause blockage, so that the steel pipe 23 cannot function normally. Rotate, and at the same time make the bending part into an arc shape, slow down the force of the steel plate, and prolong the service life of the steel plate; similarly, the connecting structure of the third steel plate and the sixth steel plate is the same as above. In addition, there is a groove in the middle range of the lower edge of the first steel plate 11 welded with the round steel 15, so as to avoid the contact between the first steel plate 11 and the steel pipe 23 and affect its rotation, thereby affecting the rotation of the antifreeze plate 2; the two steel plates of the antifreeze plate 2 rotate When reaching the horizontal direction, the edges are flush with each other and seamlessly fitted, thereby preventing cold wind from entering. Preferably, an angle steel 24 is also provided at the joint of the fifth steel plate 21 and the sixth steel plate edge, which is used as a reinforcing rib to increase the strength of the antifreeze plate 2. strength, so that it is not easily deformed; antifreeze plate 2 and two steel plates are respectively welded with a counterweight 3 at the outer end of the slide channel 1, and the counterweight 3 is a cube welded by six steel plates, filled with concrete or scrap steel, etc., each counterweight 3 is also connected with a suspension 4, the length of suspension 4 is just in time to ensure that the antifreeze plate 2 is in a horizontal state for making the counterweight 3 position, specifically can be decided according to the actual situation on the spot. The lower surface of the antifreeze plate 2 is also provided with a thermal insulation plate 5, thereby protecting the warehouse mouth from freezing and ensuring the smooth loading of materials.

The working principle of the coal bunker antifreeze device provided in this embodiment is that when there is no material in the chute 1, the hanging 4 restrains the counterweight 3 to keep the antifreeze plate 2 level, which can block the cold wind from pouring into the hopper and then into the coal bunker operation room , at this time, the warehouse mouth is not discharging, if there is no restraint by the suspension 4, the antifreeze plate 2 will be tilted towards the inside of the slide channel 1 due to the gravity of the counterweight 3, so that the material cannot be discharged; when the slide channel 1 After accumulating a certain thickness of raw coal discharged from the warehouse, the weight of the raw coal breaks the balance of the counterweight 3, and the antifreeze plate 2 relies on the gravity of the coal to drive the steel pipe 3 to rotate around the round steel 2, thereby automatically opening the closed material sliding channel, and the material loading. It should be noted that the weight of the counterweight 3 should not be too large, otherwise a large amount of coal needs to be accumulated and the antifreeze plate 2 can be washed away, which is also not conducive to the loading of coal.

Example 2

The difference between this embodiment and embodiment 1 is that the size of the fifth steel plate 21 and the sixth steel plate are larger than those in embodiment 1, so the welding places between them and the steel pipe 23 can be determined according to the needs, specifically the fifth steel plate 21 and the sixth steel plate. The antifreeze plate 2 that steel plate is formed can be as the criterion for fully sealing the material chute 1.
