Description

Technical Field

[0001] This utility model relates to an adjustable dusting direction ultrafine powder ship dusting cap, belonging to the technical field of port bulk ship loading equipment. Background Technology

[0002] When loading ultrafine powder onto bulk carriers at the port, the ultrafine powder transport tankers are first parked at the edge of the wharf. Then, the powder is loaded onto the carrier via a slurry pipe connected to a slurry cap. Each hold has two slurry caps arranged diagonally opposite each other on the hold cover. During loading, the frequency and pressure of the slurry truck operations cause uneven feed rates between the two slurry caps. Because existing slurry caps only have a downward slurry function and cannot adjust the slurry position, ship deviation frequently occurs. When ship deviation occurs, it can only be adjusted by controlling the amount of powder discharged from the trucks, severely impacting the loading rate. Therefore, developing a ship slurry cap with dynamically adjustable slurry direction is highly practical for adjusting ship deviation without affecting the loading rate. Utility Model Content

[0018] This utility model consists of a receiving tee 1, a rotating guide pipe 2, a drive handle 3, a flange plate 4, a dust cap cover 5, a limiting sleeve 6, and a limiting baffle 7.

[0019] Figure 1 , 2The receiving tee 1 consists of two receiving pipes 8 and a receiving cylinder 9, which is cylindrical. The inlet ends of the two receiving pipes 8 of the receiving tee 1 each have continuous inverted conical interface structures, which are connected to the ash-discharging pipe. The lower ends of the two receiving pipes 8 are connected to the top surface of the receiving cylinder 9. The material conveyed by the ash-discharging pipe enters the receiving cylinder 9 through the receiving pipes 8. The bottom surface of the receiving cylinder 9 has a connecting hole for connecting the rotating guide pipe 2.

[0020] Figure 1 , 3 The rotary guide tube 2 is a long tube. A ring 10 is welded to the circumference of the upper end of the rotary guide tube 2. The diameter of the rotary guide tube 2 matches the diameter of the connecting hole on the bottom surface of the receiving cylinder 9 of the receiving tee 1. The upper end of the rotary guide tube 2 is embedded in the connecting hole on the bottom surface of the receiving cylinder 9. The ring 10 at the upper end of the rotary guide tube 2 is locked above the connecting hole on the bottom surface of the receiving cylinder 9. The rotary guide tube 2 can rotate in the connecting hole of the receiving cylinder 9 to adjust the feeding point of the rotary guide tube 2.

[0021] Figure 1 , 3 The rotary guide tube 2 has a toothed ring 11 welded to its middle section. The toothed ring 11 can drive the rotary guide tube 2 to rotate, and the toothed ring 11 is rotated by the drive handle 3. The lower part of the rotary guide tube 2 has a guide elbow 12. By rotating the drive handle 3, the rotary guide tube 2 can be rotated, and the guide elbow 12 of the rotary guide tube 2 can adjust the material direction.

[0022] Figure 1 , 4 The drive handle 3 is a T-shaped long rod. A gear 13 is fixedly mounted on the lower part of the drive handle 3, and the gear 13 meshes with the gear ring 11 in the middle of the rotating guide tube 2. Rotating the drive handle 3 causes the gear 13 to drive the gear ring 11 to rotate, thereby driving the rotating guide tube 2 to rotate. The ratio of the number of circumferential teeth between the gear 13 at the lower part of the drive handle 3 and the gear ring 11 in the middle of the rotating guide tube 2 is 1:4, that is, for every 4 rotations of the gear 13 at the lower part of the drive handle 3, the gear ring 11 in the middle of the rotating guide tube 2 rotates 1. The operator can set the direction of the guide bend 12 at the lower part of the rotating guide tube 2 by calculating the number of rotations of the drive handle 3.

[0023] Figure 1The flange plate 4 is a disc, placed on the ship's hold cover. The bottom surface of the receiving cylinder 9 of the receiving tee 1 is fixedly connected to the flange plate 4. The flange plate 4 has a central hole. The rotating guide pipe 2, located below the bottom surface of the receiving cylinder 9 of the receiving tee 1, passes through the central hole of the flange plate 4 and is inserted into the ship's hold. The gear ring 11 in the middle of the rotating guide pipe 2 is located below the flange plate 4. The flange plate 4 has holes on both sides. The lower parts of the long rods of the two drive handles 3 pass through the holes in the flange plate 4, and the long rods of the drive handles 3 are in a rotating fit with the holes in the flange plate 4.

[0024] Figure 1 The flange plate 4 has a dust removal cap 5, which is a cylindrical body fitted over the receiving tee 1. The cylindrical body of the dust removal cap 5 has two round holes on its side wall, through which the two receiving pipes 8 of the receiving tee 1 connect to the dust removal pipes. The lower edge of the cylindrical body of the dust removal cap 5 is welded to the flange plate 4. The upper end of the cylindrical body of the dust removal cap 5 is sealed with a top surface, and round holes are located on both sides of the top surface. The long rods of the two drive handles 3 pass through the round holes on the top surface of the dust removal cap 5, and the long rods of the drive handles 3 are in a rotating fit with the round holes. A positioning disc 14 is fixedly connected to the long rod of the drive handle 3 above the round hole. The disc surface of the positioning disc 14 is in sliding fit with the top surface of the dusting cap protective cover 5. The function of the positioning disc 14 is to position the drive handle 3, prevent the drive handle 3 from moving downward, and keep the gear 13 of the drive handle 3 in stable mesh with the gear ring 11 of the rotating guide tube 2.

[0025] Figure 1 The display shows that a limiting sleeve 6 is located below the flange plate 4. The limiting sleeve 6 is fitted around the outer periphery of the rotating guide pipe 2 below the flange plate 4. The lower end of the limiting sleeve 6 is located above the guide elbow 12 of the rotating guide pipe 2, without affecting the rotation of the guide elbow 12. A vertical limiting baffle 7 is welded to the inner wall of the limiting sleeve 6. The limiting baffle 7 is made of angle steel, and the lower part of the limiting baffle 7 is located on one side of the guide elbow 12 of the rotating guide pipe 2, which can limit the rotation of the guide elbow 12.

[0026] The usage process of this utility model is as follows:

[0027] When in use, insert the limiting sleeve 6 into the feed hole of the ultrafine powder ship's hold cover plate, and then insert the rotating guide pipe 2 into the hold. Place the flange plate 4 on the hold cover plate, adjust the orientation of the receiving tee 1, and connect the ash-discharging pipe with the receiving pipe 8 of the receiving tee 1.

[0028] Before loading, rotate the drive handle 3 to make the rotating guide tube 2 contact the limiting baffle 7 of the limiting sleeve 6, that is, adjust to the initial position when the drive handle is rotated in one direction without moving.

[0029] After the adjustment is in place, the feeding operation begins. If the ship deviates from its course during the feeding operation, the drive handle 3 is rotated in the opposite direction to adjust the feeding point position. The lower gear 13 of the drive handle 3 drives the middle gear ring 11 of the rotating guide tube 2 to rotate, thereby driving the rotating guide tube 2 to rotate and adjust the orientation of the guide bend 12. This achieves the function of adjusting the feeding point position during the operation, and solves the problem of ship deviating from its course without affecting the loading rate.
