[0001] The utility model relates to the technical field of chemical containers, in particular to a powder material conveying device for a chemical container. Background Art

[0002] In some chemical container applications, such as desulfurization towers and desulfurization tanks, the only access to the desulfurization tower is a DN500 manhole, making it difficult for larger machinery to enter directly for operation. Furthermore, before each sulfur cleaning operation, sulfur accumulates so heavily inside the desulfurization tower that it often exceeds the top edge of the bottom manhole, making it extremely difficult to assemble the complete equipment components inside the tower after entering through the manhole. Therefore, sulfur cleaning operations within desulfurization towers are currently performed manually by gradually digging inward.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0046] In addition, in the description of the present invention, unless otherwise specified, “a plurality of” means two or more.

[0047] like Figures 1 to 5 The figure shows an embodiment of the chemical container powder conveying device of the present utility model.

[0048] See also Figure 1 and Figure 2 The chemical container powder conveying device of this embodiment includes a screw conveyor 1. The screw conveyor 1 is installed in a chemical container 2 and has a feed port 11 and a discharge port 12. The feed port 11 and the discharge port 12 are respectively located at both ends of the screw conveyor 1 and are connected through the screw conveyor 1. The feed port 11 is located inside the chemical container 2 and is used to receive powder. The powder enters the interior of the screw conveyor 1 through the feed port 11. The discharge port 12 is located outside the chemical container 2. The screw conveyor 1 is used to convey the powder received by the feed port 11 to the discharge port 12 for discharge.

[0049] Therefore, when the chemical container powder conveying device of this embodiment is used, the operator extends the end of the screw conveyor 1 provided with the feed port 11 through the manhole 2a of the chemical container 2 into the interior of the chemical container 2, and sets the discharge port 12 on the outside of the chemical container 2. The screw conveyor 1 is started, and then the powder is loaded into the interior of the screw conveyor 1 through the feed port 11 inside the chemical container 2. The screw conveyor 1 conveys the received powder from the feed port 11 to the discharge port 12, and discharges the powder from the discharge port 12, thereby achieving efficient and continuous conveyance of the powder inside the chemical container 2 to the outside of the chemical container 2, which can significantly improve the efficiency of cleaning the powder inside the chemical container 2.

[0050] See also Figure 1 and Figure 2 Preferably, the screw conveyor 1 includes a sleeve 13, a spiral blade 14 and a motor 15, and the feed port 11 and the discharge port 12 are respectively provided at the two ends of the sleeve 13. The spiral blade 14 is inserted into the sleeve 13, and the spiral blade 14 extends from the feed port 11 to the discharge port 12. The motor 15 is used to drive the spiral blade 14 to rotate. Preferably, the motor 15 is provided at the end of the screw conveyor 1 provided with the discharge port 12 and is connected to the spiral blade 14. When in use, the end of the sleeve 13 provided with the feed port 11 is passed through the manhole of the chemical container 2 and entered into the interior of the chemical container 2, and the end of the sleeve 13 provided with the discharge port 12 is provided outside the chemical container 2. When filling the powder, the powder enters the interior of the sleeve 1 from the feed port 11, and the spiral blade 14 stirs the powder and pushes the powder to move along the spiral path toward the discharge port 12, and finally discharged from the discharge port 12.

[0051] Furthermore, the chemical container powder conveying device of this embodiment can also adapt to different operating environments by extending the length of the sleeve 13 and spiral blade 14. Preferably, the spiral blade 14 is made of a metal material, and at least two sections of the spiral blade 14 are coaxially connected to ensure that the spiral path of the connected spiral blade 14 is continuous. The connection is then welded to extend the length of the spiral blade 14. The sleeve 13 is preferably a black rubber tube, and at least two sections of the sleeve 13 are coaxially connected and fixed at the connection to extend the length of the sleeve 13.

[0052] See also Figures 3 to 5Preferably, the spiral blade 14 is connected to a first rotating shaft 14a and a second rotating shaft 14b at both ends, and the axes of the first rotating shaft 14a and the second rotating shaft 14b coincide with the spiral centerline of the spiral blade 14. The first rotating shaft 14a is connected to the motor 15, and the second rotating shaft 14b is rotatably connected to the sleeve 13, so that the spiral blade 14 can rotate freely relative to the sleeve 13. When the motor drives the first rotating shaft 14a to drive the spiral blade 14 to rotate, the spiral blade 14 can rotate around the spiral centerline, thereby avoiding radial deviation of the spiral blade 14 during rotation, which may cause wear on the inner wall surface of the sleeve 13, and improving the stability of the spiral blade 14 during rotation.

[0053] See also Figure 3 Preferably, the screw conveyor 1 further comprises a transmission structure 16, and the spiral blade 14 and the motor 15 are connected via the transmission structure 16. The transmission structure 16 can be set to various forms such as gear transmission, sprocket transmission, pulley transmission, or coupling transmission.

[0054] In this embodiment, the transmission structure 16 preferably includes a first pulley 16a, a second pulley 16b, and a transmission belt 16c. The motor 15 is coaxially connected to the first pulley 16a, and the spiral blade 14 is coaxially connected to the second pulley 16b. The first pulley 16a and the second pulley 16b are connected by a transmission belt. Preferably, the transmission ratio from the motor 15 to the spiral blade 14 is a reduction transmission ratio. Therefore, the diameter of the first pulley 16a is smaller than the diameter of the second pulley 16b. The speed of the spiral blade 14 during rotation is less than the speed output by the motor 15. This allows the spiral blade 14 to rotate at a speed suitable for powder conveying, which is beneficial for smooth powder conveying and reduces wear on the conveying device.

[0055] See also Figure 3 and Figure 4 Preferably, the chemical container powder conveying device of this embodiment further includes a trolley 3. The end of the screw conveyor 1 provided with the discharge port 12 is disposed on the trolley 3. The trolley 3 is used to move and position the end of the screw conveyor 1 provided with the discharge port 12. By pushing the trolley 3, the end of the screw conveyor 1 provided with the discharge port 12 can be quickly moved to the location where the powder needs to be discharged, reducing the labor intensity and time cost of manual handling. Preferably, a motor 15 is also disposed on the trolley 3, making it easier for the operator to start the motor 15 after positioning the trolley 3.

[0056] See also Figure 5Preferably, the screw conveyor 1 further comprises a feed hopper 17. The interior of the feed hopper 17 is hollow to form a cavity 17a. The two ends of the cavity 17a are connected to form an inlet 17b and an outlet 17c respectively. The cross-sectional area of ​​the cavity 17a gradually increases from the outlet 17c to the inlet 17b. The outlet 17c is connected to the feed port 11. The inlet 17b is used to receive the powder. The inlet 17b of the feed hopper 17 is wider than the feed port 11. When filling the powder, the inlet 17b of the feed hopper 17 is facing upward. Under the action of gravity, the powder enters the cavity 17a of the feed hopper 17 from the wider inlet 17b, and then enters the interior of the sleeve 1 from the outlet 17c. The wider inlet 17b makes it easier for the operator to load the powder into the feed hopper 17, thereby improving the efficiency of powder filling.

[0057] See also Figure 3 Preferably, the machine further includes a hopper 4 for receiving the powder discharged from the discharge port 12. The hopper 4 is located below the discharge port 12, and the powder discharged from the discharge port 12 falls directly into the hopper 4 for collection. Furthermore, when collecting the powder, a bag can be placed directly on the discharge port 12 to place the discharged powder into the bag. In this case, the hopper 4 is used to receive the powder spilled from the bag to prevent the powder from spilling directly onto the ground.

[0058] The working process of the chemical container powder conveying device of this embodiment is as follows:

[0059] Preparation stage: The operator inserts the end of the sleeve 13 with the feed port 11 into the interior of the chemical container 2 through the manhole 2a of the chemical container 2. The discharge port 12 is located outside the chemical container 2 and fixed on the trolley 3. The trolley 3 is moved to drive the discharge port 12 to a position suitable for discharging powder, and then the trolley is fixed.

[0060] Start the motor 15 : Start the motor 15 and confirm that the rotation direction of the motor 15 is correct so that the spiral blade 14 rotates in the expected direction to push the powder to move from the feed port 11 of the sleeve 13 to the discharge port 12 .

[0061] Filling powder: Powder is loaded through the inlet 17 b of the feed hopper 17 , and the powder flows from the cavity 17 a of the feed hopper 17 into the feed port 11 and finally into the interior of the sleeve 13 .

[0062] Powder conveying: The powder is stirred by the spiral blades 14 inside the sleeve 13 and continuously conveyed from the feed port 11 to the discharge port 12.

[0063] Powder discharge: The powder reaches the discharge port 12 and is discharged from the sleeve 13 and falls into the hopper 4. The hopper 4 is used to receive and temporarily store the powder discharged from the discharge port 12 for the next step of processing or packaging.

[0064] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
