Description

Technical Field

[0001] The utility model relates to the field of single-cooling machines, in particular to a hood and a single-cooling machine including the hood. Background Art

[0002] In the process of clinker production, it is necessary to cool the clinker sintered at high temperature. The single-cooling machine plays an important role in the clinker burning system, mainly responsible for cooling the high-temperature clinker through air. Specifically, air is introduced into the equipment as a cooling medium to exchange heat with the high-temperature clinker. The existing discharge port of the single-cooling machine is directly in contact with the air, and the discharged clinker is completely exposed to the external air. Under the negative pressure in the single-cooling machine, the external cold air of the single-cooling machine enters the single-cooling machine system without restraint, and the cooling speed and temperature of the clinker cannot be accurately controlled, which cannot meet the production process requirements. Summary of the Invention

[0003] In order to solve the above problems, the utility model provides a hood and a single-cooling machine including the hood, aiming to solve the problem that the cooling speed and temperature of the clinker cannot be accurately controlled, and at the same time prevent the materials and hot air flow from spraying out when the single-cooling machine is under positive pressure or the kiln system collapses.

[0004] In order to achieve the above object, the utility model adopts the following technical scheme: A hood, the hood includes a hood part and a mask part, the hood part is fixedly connected to the mask part, the hood part is an arched structure, the shape of the mask part is the same as the cross-sectional shape of the hood part, a door opening is provided at the center of the mask part, and a movable door for adjusting the air volume is installed on the door opening.

[0005] Upper and lower sliding channels are provided at the upper and lower ends of the movable door, a pulley is installed at the lower end of the movable door, and the pulley is in transmission connection with the lower sliding channel.

[0006] Electric screw rods are installed on both sides of the movable door.

[0007] A single-cooling machine including a hood, comprising a single-cooling machine main body and a discharge support, the discharge support is installed at the bottom end of the discharge port of the single-cooling machine main body, and further includes the above-mentioned hood, and the hood part of the hood is fixedly connected to the outer wall of the single-cooling machine main body.

[0008] The distance from the mask part to the discharge port of the single-cooling machine main body is X, and the width of the feed opening of the discharge support is Y, and X≥Y.

[0009] The mask part is fixedly connected to the discharge support.

[0010] Advantages of the present utility model: By installing a hood at the discharge port end of the single-cooling machine, it is possible to prevent the clinker discharged from the single-cooling machine from being completely exposed to the outside air. The air intake volume is adjusted by changing the opening degree of the movable door on the mask part, thereby controlling the cooling speed and temperature of the clinker. At the same time, since the hood covers the discharge port of the single-cooling machine, when the single-cooling machine is under positive pressure or the kiln system collapses, the material and hot air flow will not spurt out, improving safety.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0015] The technical solutions of the present utility model will be described in detail below with specific embodiments. These specific embodiments can be combined or replaced according to the actual situation. For the same or similar concepts or processes, they may not be repeated in some embodiments. Embodiment

[0016] As Figures 1 to 2 shown, a hood, the hood 1 includes a hood part 11 and a mask part 12. The hood part 11 and the mask part 12 are fixedly connected by welding. The hood part 11 is of an arch-like structure. The shape of the mask part 12 is the same as the cross-sectional shape of the hood part 11. A door opening 121 is provided in the center of the mask part 12, and a movable door 4 for adjusting the air volume is installed on the door opening 121. The single-cooling machine using the above hood further includes a single-cooling machine main body 2 and a discharge support 3. The discharge support 3 is installed at the bottom end of the discharge port of the single-cooling machine main body 2. The hood part 11 of the hood 1 is fixedly connected to the outer wall of the single-cooling machine main body 2. Specifically, a circle of steel plates is welded to the outer wall of the single-cooling machine main body 2, and then the hood part 11 is welded to the steel plates, so as to realize the fixed connection between the hood part 11 and the outer wall of the single-cooling machine main body 2.

[0017] Further, in order to better fix the hood 1 and enable the hood 1 to resist the impact of the hot air flow of the clinker when the single-cooler is under positive pressure or the kiln system collapses, the mask part 12 is fixedly connected to the discharge support 3; the air intake volume of the single-cooler main body 2 is adjusted by manually adjusting the opening degree of the movable door 4, so as to control the cooling speed and temperature of the clinker. Due to the shielding of the hood 1, the dust generated in the clinker preparation is also effectively treated; in order to enable the clinker to be smoothly transported by the discharge support 3 after cooling, the distance from the mask part 12 to the discharge port of the single-cooler main body 2 is X, and the feed opening width of the discharge support 3 is Y, where X≥Y.
