Description

Technical Field

[0001] The utility model relates to the technical field of iron powder collection, and more specifically, to an iron powder collecting device for steel shot blasting equipment. Background Art

[0002] Shot blasting involves projecting steel grit and shot at high speed onto the surface of a material. Compared to other surface treatment technologies, it is faster and more efficient, and can also be used for partially retained or post-press casting processes. Therefore, it is widely used in steel production and processing. The shot blasting process generates a large amount of iron powder. To prevent waste and environmental pollution, shot blasting machines are typically equipped with an iron powder collection device to recover the powder for reuse.

[0003] Traditional iron powder collection devices for steel shot blasting equipment generally use a collection bag suspended on the dust exhaust pipe of the shot blasting machine dust removal system to collect iron powder. For example, Publication No.: CN206677798U discloses a dust collection device suitable for the shot blasting machine dust removal system. This device is used to collect dust discharged from the shot blasting machine dust removal system by providing a collection bag, and a corresponding hanging device for hanging the collection bag. After the collection bag is full, it can be directly bundled and placed in a designated storage area, thereby reducing dust flying and improving dust collection efficiency. In the above-mentioned traditional iron powder collection device, due to the gap between the collection bag and the dust exhaust pipe, dust flying still occurs. Therefore, Publication No.: CN216030236U discloses a shot blasting machine dust collection device. This shot blasting machine dust collection device introduces dust into an adsorption treatment box, promptly mixes the dust with water to form dust-containing sewage, and finally discharges it into a collection container through a sewage discharge pipe, thereby avoiding environmental pollution.

[0004] In the above-mentioned iron powder collection device, the former uses a collection bag collection method, which still has the problem of dust flying, while the latter adopts a water spraying method and finally discharges it through sewage discharge. Although it can solve the problem of secondary dust, the iron powder is mixed with water, which is not convenient to discharge from the adsorption treatment box, resulting in difficulties in subsequent recycling.

[0005] Therefore, it is urgent to develop and design a new type of iron powder collecting device for steel shot blasting equipment. Utility Model Content

[0006] The technical problem to be solved by the present invention is to address the above-mentioned deficiencies in the prior art. The purpose of the present invention is to provide an iron powder collecting device for steel shot blasting equipment, which can prevent iron powder from flying and polluting the environment while enabling convenient and rapid recovery of iron powder.

[0007] In order to achieve the above object, the utility model provides a iron powder collection device for a steel shot blasting equipment, which includes a collection bag and a connecting pipe. The connecting pipe is fixedly sleeved on the lower part of a dust exhaust pipe. The diameter of the connecting pipe is larger than that of the dust exhaust pipe. The collection bag is suspended below the connecting pipe through a suspension device. At least one spray gun is arranged on the suspension device, and the spray opening of each spray gun is arranged directly below the connecting pipe. A solenoid valve is arranged on the pipeline corresponding to each spray gun. An articulated seat is arranged on the inner wall of the connecting pipe. A baffle is hinged and installed on the articulated seat through a hinge shaft. The outer wall of the baffle fits the inner wall of the connecting pipe. One end of the hinge shaft penetrates through the connecting pipe and is connected with a trigger component. A proximity switch is arranged on one side of the trigger component. The proximity switch is electrically connected with the solenoid valve corresponding to the spray gun through a controller.

[0008] As a further improvement, the trigger component includes a trigger rod and a counterweight. One end of the trigger rod is fixedly connected with the hinge shaft, and the other end is connected with the counterweight. The proximity switch is located above the trigger rod.

[0009] Further, the counterweight and the trigger rod are detachably connected.

[0010] Further, a limiting block is arranged at one end of the inner wall of the connecting pipe far away from the articulated seat. The limiting block is a conical block with a gradually increasing cross-sectional width from the top of the connecting pipe downwards. One end of the baffle far away from the articulated seat fits the bottom surface of the limiting block.

[0011] Further, the suspension device includes several support rods. One end of each support rod is fixedly connected with the connecting pipe, and a hook is arranged at the other end of each support rod. The collection bag is suspended on the hook, and the spray gun is installed on the support rod.

[0012] Further, the spray gun and the support rod are detachably connected.

[0013] Further, the number of the support rods is consistent with the number of the spray guns, and several support rods are evenly distributed around the central line of the connecting pipe.

[0014] Further, a support platform is arranged below the connecting pipe, and the collection bag is placed on the support platform.

[0015] Further, the support platform includes a support groove with an inner groove opened at the top and multiple support legs. The collection bag is placed in the support groove, and multiple support legs are evenly fixed at the bottom of the support groove.

[0016] Beneficial effects

[0017] Compared with the prior art, the utility model has the following advantages:

[0018] 1. The iron powder collection device of the present invention arranges a collection bag under the dust exhaust pipe and a spray gun at the same time. The iron powder comes out of the dust exhaust pipe and falls into the collection bag, which makes it convenient for a subsequent forklift to directly remove the collection bag. When the iron powder falls, the spray gun sprays the iron powder to prevent the iron powder from flying and polluting the environment. At the same time, it will not cause the loss of iron powder, and can quickly and conveniently recover the iron powder. In addition, it uses water to contact with the iron powder to form agglomerates, so there is no need to add water to form agglomerates in the subsequent steelmaking, which saves processes and improves efficiency.

[0019] 2. The iron powder collection device of the present invention is provided with a baffle in the connecting pipe, and the baffle cooperates with the trigger assembly and the proximity switch. In actual use, the iron powder falls on the baffle. When the amount of iron powder accumulated on the baffle is greater than the weight of the trigger assembly, the baffle flips downward to achieve intermittent falling of the iron powder; when the baffle flips, the hinged shaft drives the trigger assembly to flip and approach the proximity switch. When the proximity switch senses the trigger assembly, it feeds back the signal to the controller, and the controller controls the solenoid valve corresponding to the spray gun to open, and the spray gun starts to spray liquid, so that the liquid is sprayed while the iron powder falls, avoiding dust, effectively saving water, reducing costs, and preventing the iron powder from being mixed in the water.

The collection bag 1 is suspended below the connecting pipe 2 through a suspension device 4. At least one spray gun 5 is provided on the suspension device 4. The spray gun 5 can be an atomization chamber with an atomizing nozzle. The atomized spraying method has a better dust suppression effect. The spray ports of each spray gun 5 are all arranged directly below the connecting pipe 2, so that the spraying liquid can face the iron powder, further improving the dust suppression effect. Solenoid valves 6 are provided on the pipelines corresponding to each spray gun 5 to control the opening or closing of the spray gun 5; A hinge seat 7 is provided on the inner wall of the connecting pipe 2. A baffle 9 is hingedly installed on the hinge seat 7 through a hinge shaft 8. Specifically, the baffle 9 is fixed on the hinge shaft 8, and the hinge shaft 8 is hingedly installed on the hinge seat 7. Both the baffle 9 and the hinge shaft 8 can rotate relative to the hinge seat 7. The outer wall of the baffle 9 fits with the inner wall of the connecting pipe 2 to close the connecting pipe 2 and form a valve. One end of the hinge shaft 8 penetrates through the connecting pipe 2 and is connected to a trigger component. Specifically, the hinge shaft 8 and the connecting pipe 2 can be connected through a sealing bearing. A proximity switch 10 is provided on one side of the trigger component. The proximity switch 10 is electrically connected to the solenoid valve 6 corresponding to the spray gun 5 through a controller, facilitating the control of the opening or closing of the spray gun 5.

[0027] For the iron powder collection device of the present utility model, by setting the collection bag 1 below the dust exhaust pipe 3 and simultaneously setting the spray gun 5, the iron powder comes out from the dust exhaust pipe 3 and falls into the collection bag 1, which is convenient for the subsequent forklift to directly remove the collection bag 1. And when the iron powder is falling, the iron powder is sprayed by the spray gun 5. While avoiding the pollution of the environment caused by the floating of the iron powder, it will not cause the loss of the iron powder, can conveniently and quickly recover the iron powder, and it uses water to contact with the iron powder to form lumps, so there is no need to add water to form lumps during subsequent steelmaking, saving the process and improving the efficiency.

[0029] The iron powder collecting device of the present invention is provided with a baffle 9 in the connecting pipe 2. The baffle 9 cooperates with the trigger assembly and the proximity switch 10. In actual use, the iron powder falls on the baffle 9. When the amount of iron powder accumulated on the baffle 9 is greater than the weight of the trigger assembly, the baffle 9 flips downward to achieve intermittent falling of the iron powder; when the baffle 9 flips, the hinge shaft 8 drives the trigger assembly to flip and approach the proximity switch 10. When the proximity switch 10 senses the trigger assembly, it feeds back a signal to the controller, and the controller controls the solenoid valve 6 corresponding to the spray gun 5 to open, and the spray gun 5 starts to spray liquid, so as to achieve spraying of liquid while the iron powder falls, avoid dust, effectively save water, reduce costs, and prevent the iron powder from being mixed in the water.
