[0002] Pneumatic conveying systems for transporting dry powdery materials offer advantages such as long conveying distances, small footprint, flexible layout, high cost-effectiveness, and continuous transport capability. They are particularly widely used in the steel and metallurgical industries for transporting powdery materials like quicklime powder, lightly calcined dolomite, and dust collector ash. The closed-loop transport of powdery materials achieves clean production requirements and ensures a stable, continuous supply of materials. However, during the production of materials like quicklime powder, it's inevitable that iron objects will be mixed in, such as worn-out equipment parts, welding rods or tools accidentally dropped during maintenance, and large debris like material packaging bags, wood blocks, and rags. These iron objects and large debris entering the conveying system can cause blockages in valves, feeders, and pipes, leading to sudden equipment shutdowns, production interruptions, and even equipment damage. If foreign object blockages occur, shutdown repairs are necessary, which are time-consuming, labor-intensive, and costly.

[0025] The vertically installed cavity structure layout allows materials to flow using gravity without requiring external power. Furthermore, once the cavity is sealed, the material flow within it prevents dust pollution. It also features low investment, simple structure, reliable operation, and cost savings.

[0026] The bottom of the shell 4 is provided with a discharge port 6; the discharge port 6 is welded to the bottom of the shell 4, and a flange is provided at the bottom of the discharge port 6, which can be connected to an external pipe by bolts.

[0027] An observation port is provided near the top of the housing 4, and an electromagnet 9 of a matching size is installed on the observation port.

The hydraulic push rod 7 is located on the same side as the electromagnet 9, and the telescopic end of the hydraulic push rod 7 is connected to the electromagnet 9 through a hinge 8.

[0028] Powdered material enters through inlet 1. When it passes through metal detector 2, iron objects in the powdered material are detected by metal detector 2, which then triggers electromagnet 9 to become energized and magnetized, attracting iron objects from the material flowing into the inner cavity of housing 4, thus achieving iron removal. Through metal detection and electromagnetic adsorption, iron objects mixed in with the material can be eliminated, solving the problems of iron objects damaging the blades of the pneumatic ash conveying disc feeder and clogging the pipes.

[0029] The inner cavity of the housing 4 is provided with a cleaning grate 3 and a dial 5 for moving the cleaning grate; a discharge port 10 for discharging debris from the cleaning grate 3 is provided on one side of the housing 4.

[0030] Non-metallic debris is blocked by the impurity removal grate 3 inside the housing 4, and then pushed from top to bottom by the impurity removal dial 5 to the impurity discharge port 10 on the side of the cavity. After the machine stops, it is cleaned through the impurity discharge port 10.

[0031] Example 2

[0032] Based on Example 1, the hydraulic push rod 7 is connected to a hinge 8 at its telescopic end.

The center of the hinge 8 is connected to the telescopic end of the hydraulic push rod 7, and the bottom of the hydraulic push rod 7 is fixed to the outer wall of the feed port 1.

[0033] The hydraulic push rod 7 extends and retracts, causing the hinge 8 to rotate around one end, which in turn causes the electromagnet 9 to rotate, opening or closing.

[0034] Example 3

[0035] The pneumatic ash conveying material iron and impurity removal device of this utility model is mainly composed of 10 components, including: feed inlet 1, metal detector 2, impurity removal grate 3, housing 4, impurity removal dial 5, discharge port 6, hydraulic push rod 7, hinge 8, electromagnet 9, and impurity discharge port 10.

[0036] Its location and connection relationship are as follows Figure 1 and Figure 2 As shown, the upper end of the metal detector 2 is connected to the feed port 1 by bolts, and the feed port 1 is connected to the flange of the powder material silo above; the lower end of the metal detector 2 is fixedly connected to the housing 4 by bolts.

[0037] The feed inlet 1 and the metal detector 2 are connected and fixed to the housing 4 by bolts, forming a whole that can be connected to other flanges of the same diameter. The internal cavity of the housing 4 becomes a channel through which the powdery material flows from top to bottom.

[0038] The bottom of the shell 4 is provided with a discharge port 6; the discharge port 6 is welded to the bottom of the shell 4, and a flange is provided at the bottom of the discharge port 6, which can be connected to an external pipe by bolts.

[0039] An observation port is provided near the top of the housing 4, and an electromagnet 9 of a matching size is installed on the observation port. A hydraulic push rod 7 is installed on the outer wall of the feed port 1. The hydraulic push rod 7 is located on the same side as the electromagnet 9, and the telescopic end of the hydraulic push rod 7 is connected to the electromagnet 9 through a hinge 8.

[0040] The inner cavity of the housing 4 is provided with a cleaning grate 3 and a dial 5 for moving the cleaning grate; a discharge port 10 for discharging debris from the cleaning grate 3 is provided on one side of the housing 4.

[0041] Furthermore, the impurity removal grate 3 is set at an angle. The dust material entering the housing 4 falls onto the impurity removal grate 3 under the action of gravity. The angled impurity removal grate 3 can screen and filter the material as it falls, avoiding accumulation in a single position and speeding up the falling speed. At the same time, the dial wheel 5 moves the impurity removal grate 3 to further accelerate the screening and falling speed of the dust material.

[0042] Furthermore, one end of the debris removal grate 3 is fixed below the top channel opening of the housing 4, and the other end is fixed at the bottom of the debris discharge port 10, serving as a debris screening and discharge channel.

[0043] The vertically installed cavity structure layout allows materials to flow using gravity without requiring external power. Furthermore, once the cavity is sealed, the material flow within it prevents dust pollution. It also features low investment, simple structure, reliable operation, and cost savings.

[0044] Example 4

[0045] Based on embodiment 3, a shaft is inserted through the center of the dial wheel 5, and both ends of the shaft are connected to the inner wall of the housing 4 via bearings. Furthermore, the radius of the dial wheel 5 is not less than the vertical distance between the center of the impurity removal grate 3 and the center of the dial wheel 5.

[0046] The motor transmits rotational torque to the shaft, causing the dial wheel 5 to rotate and push the debris on the debris removal grate 3 to the debris discharge port 10 on the side of the cavity.

[0047] Example 5

[0048] Based on Example 4, with the hydraulic push rod 7 extended, the electromagnet 9 presses against the observation port.

[0049] The electromagnet 9, which can be flipped and moved, is pressed against the observation port of the housing 4 by the pressure of the hydraulic push rod 7. The electromagnet 9 and the housing 4 form a sealed space, which prevents dust from leaking into the atmosphere during the transportation process, effectively reducing dust pollution to the environment and improving the working environment and surrounding air quality.

[0050] Example 6

[0051] Based on Example 5, the discharge port 10 is welded to the housing 4, and a sealing cap is installed on the discharge port 10.

[0052] After the sealing cover of the discharge port 10 is sealed, it forms a closed space with the housing 4, which prevents dust from leaking into the atmosphere during the transportation process, effectively reducing dust pollution to the environment and improving the working environment and surrounding air quality.

[0056] The bottom of the shell 4 is provided with a discharge port 6; the discharge port 6 is welded to the bottom of the shell 4, and a flange is provided at the bottom of the discharge port 6, which can be connected to an external pipe by bolts.

[0057] An observation port is provided near the top of the housing 4, and an electromagnet 9 of a matching size is installed on the observation port. A hydraulic push rod 7 is installed on the outer wall of the feed port 1. The hydraulic push rod 7 is located on the same side as the electromagnet 9, and the telescopic end of the hydraulic push rod 7 is connected to the electromagnet 9 through a hinge 8.

[0058] The inner cavity of the housing 4 is provided with a cleaning grate 3 and a dial 5 for moving the cleaning grate; a discharge port 10 for discharging debris from the cleaning grate 3 is provided on one side of the housing 4.

[0059] Furthermore, the impurity removal grate 3 is set at an angle. The dust material entering the housing 4 falls onto the impurity removal grate 3 under the action of gravity. The angled impurity removal grate 3 can screen and filter the material as it falls, avoiding accumulation in a single position and speeding up the falling speed. At the same time, the dial wheel 5 moves the impurity removal grate 3 to further accelerate the screening and falling speed of the dust material.

[0060] Furthermore, one end of the debris removal grate 3 is fixed below the top channel opening of the housing 4, and the other end is fixed at the bottom of the debris discharge port 10, serving as a debris screening and discharge channel.

[0061] The vertically installed cavity structure layout allows materials to flow using gravity without requiring external power. Furthermore, once the cavity is sealed, the material flow within it prevents dust pollution. It also features low investment, simple structure, reliable operation, and cost savings.

[0062] Furthermore, the extension end of the hydraulic push rod 7 is connected to a hinge 8.

The center of the hinge 8 is connected to the extension end of the hydraulic push rod 7, and the bottom of the hydraulic push rod 7 is fixed to the outer wall of the feed port 1.

[0063] The discharge port 10 is welded to the housing 4, and a sealing cover is installed on the discharge port 10.

[0064] The working process of this utility model of a pneumatic ash conveying material iron and impurity removal device is as follows: Figure 2 As shown:

[0065] Powdered material falls from the hopper and enters the metal detector 2 through the feed inlet 1. When the powdered material passes through the inside of the metal detector 2, the iron objects in the powdered material are detected by the metal detector 2, which then triggers the electromagnet 9 to become energized and magnetized. As the material flows into the inner cavity of the shell 4, the iron objects in the material are attracted out by the electromagnet 9 to achieve the iron removal function.

[0066] Non-metallic debris is blocked by the cleaning grate 3 inside the housing 4, and then pushed from top to bottom by the cleaning wheel 5 to the discharge port 10 on the side of the cavity. After the machine stops, it can be discharged through the discharge port 10. Scrap iron attracted by the electromagnet 9 can be cleaned after the machine stops by the hydraulic push rod 7 pulling the hinge 8 to open the electromagnet cover.

[0067] After the iron and impurities are removed, the powdery material continues to fall through the impurity removal grate 3 into the shell 4, and enters the pneumatic ash conveying feeding system through the discharge port 6. After iron and impurities are removed, the powdery material is smoothly sent to the receiving bin through the valves, equipment and pipelines of the pneumatic ash conveying system.

[0068] The advantages of this pneumatic ash conveying material iron and impurity removal device are as follows:

[0069] A metal detector 2 is installed below the feed inlet 1 and an electromagnet 9 is installed at the observation port of the housing 4. Through metal detection and electromagnetic adsorption, iron objects mixed in with the material can be eliminated, solving the problem of iron objects damaging the blades of the pneumatic ash conveying disc feeder and clogging the pipes.

[0070] The impurity removal grate 3 and impurity removal wheel 5 are installed inside the housing 4. The impurity removal grate 3 can block and filter large particles and non-ferrous impurities in the powdered material, and the impurity removal wheel 5 can transfer the impurities to the discharge port 10, clearing the falling channel of the powdered material and not affecting the passage of the powdered material, thus solving the problem of screening non-ferrous impurities in the material.

[0071] The vertically installed cavity structure layout allows materials to flow using gravity without requiring external power. Furthermore, once the cavity is sealed, the material flow within it prevents dust pollution. It also features low investment, simple structure, reliable operation, and cost savings.
