Description

Technical Field

[0001] The utility model belongs to the technical field of protective slag preparation, and particularly relates to an automatic feeding device for protective slag preparation. Background Art

[0002] During the preparation process of protective slag, a batching device needs to add a variety of raw materials to a conveyor belt, and the conveyor belt transports the raw materials to a mixing device for mixing. The raw materials for preparing protective slag are mostly powdered raw materials. When the conveyor belt transports the powder to the silo of the mixing device, the powder will generate a large amount of flying dust. Currently, dust reduction equipment or negative pressure dust collection equipment is used in conjunction with a filter to deal with the dust. However, the dust reduction equipment or the negative pressure dust collection equipment requires additional energy to drive, which will increase energy loss and increase the production cost when preparing protective slag.

[0015] Please refer to Figures 1 - 3 , the present utility model provides the following technical solutions: An automatic feeding device for preparing protective slag, including a protective slag raw material conveyor belt 1, a support frame 2 fixedly connected to the side wall of the protective slag raw material conveyor belt 1, a top dense dust-proof wool 21 fixedly connected to the bottom end of the support frame 2, a support frame plate 3 fixedly connected to the bottom end of the support frame 2, an elastic interception cloth 31 fixedly connected to the bottom end of the support frame plate 3, a relief groove 32 opened on the side wall of the support frame plate 3, an elastic connecting rope sleeve 4 fixedly connected to the bottom end of the elastic interception cloth 31, two connecting cloths 41 fixedly connected to the bottom end of the elastic connecting rope sleeve 4, and creases 5 are provided on both the elastic interception cloth 31 and the connecting cloth 41.

[0016] In this implementation: When preparing the mold powder, the raw material ratio of the mold powder is fed onto the top of the mold powder raw material conveyor belt 1 through the batching mechanism. The mold powder raw material conveyor belt 1 conveys the raw materials to the mixing device. After the raw materials are conveyed to the tail end, they are fed into the bin of the mixing device under the action of gravity and inertia. During the conveyance of the raw materials, with the help of the support frame 2, a semi-closed space is formed in cooperation with the support frame plate 3 and the elastic interception cloth 31. The top dense dust-proof hairs 21 and the bottom dense dust-proof hairs 33 cooperate to block the gaps between the support frame 2 and the support frame plate 3 and the mold powder raw material conveyor belt 1, which can intercept and protect the space between the mold powder raw material conveyor belt 1 and the stirring device, preventing the scattered powder from escaping outward to protect the environment of the production workshop. The elastic interception cloth 31 and the connecting cloth 41 are both in a relaxed state with a margin. Both the elastic interception cloth 31 and the connecting cloth 41 have creases 5, and both the elastic connection rope sleeve 4 and the elastic limit rope sleeve 42 have elasticity, so that the bottom opening of the elastic interception cloth 31 and the elastic connection rope sleeve 4, the connecting cloth 41 and the elastic limit rope sleeve 42 can be adjusted to different diameters, enabling the device to be quickly installed on the top of the stirring bin with different opening areas, making it more convenient to use. During specific installation, the staff adjusts the tail end of the mold powder raw material conveyor belt 1 to the top of the bin of the mixing device. Then, the staff expands the elastic connection rope sleeve 4 and the elastic limit rope sleeve 42, and slews the two connecting cloths 41 and the elastic limit rope sleeves 42 on both sides of the top of the bin of the mixing device. Subsequently, the elastic connection rope sleeve 4 and the elastic limit rope sleeve 42 contract under their own elastic force, contracting the connecting cloth 41 on both sides of the bin of the mixing device.

[0017] The bottom dense dust-proof hairs 33 are fixedly connected to the top wall of the elastic interception cloth 31, and a conveyor belt cleaning brush 34 is fixedly connected to one side of the bottom dense dust-proof hairs 33; by setting the bottom dense dust-proof hairs 33, the gap between the conveyor belt of the mold powder raw material conveyor belt 1 and the support frame plate 3 can be blocked, preventing the scattered dust from overflowing through the gap between the conveyor belt of the mold powder raw material conveyor belt 1 and the support frame plate 3. By setting the conveyor belt cleaning brush 34, the conveyor belt of the mold powder raw material conveyor belt 1 can be cleaned, enabling the dust attached to the conveyor belt of the mold powder raw material conveyor belt 1 to fall into the bin of the mixing device. There is a gap between the conveyor belt cleaning brush 34 and the bottom dense dust-proof hairs 33, which is convenient for the dust to fall.

[0018] The elastic traction net 35 is fixedly connected to the inner wall of the elastic interception cloth 31, and the elastic traction net 35 is located at the top opening position of the elastic interception cloth 31; when the raw materials fall downward, they will hit the elastic traction net 35, driving the elastic traction net 35 to bend downward. Through the elastic traction net 35, the support frame plate 3 and the elastic interception cloth 31 are driven to vibrate, and the dust attached to the elastic interception cloth 31 can fall downward. The support frame plate 3 is a rigid plate. When the elastic interception cloth 31 drives the support frame plate 3 to vibrate, the vibration amplitude of the support frame plate 3 is significantly smaller than that of the elastic interception cloth 31.

[0019] Elastic limit rope sleeves 42 are fixedly connected to the bottom ends of both connecting cloths 41. A number of evenly distributed connecting pieces 43 are fixedly connected to the bottom ends of the elastic limit rope sleeves 42. By providing the connecting cloth 41 and the elastic limit rope sleeve 42, it is convenient to connect the elastic intercepting cloth 31 to the silo of the mixing device, so that the powder can fall downward along the elastic intercepting cloth 31 and the connecting cloth 41. Moreover, the elastic limit rope sleeve 42 can contract under its own elastic force to fix the connecting cloth 41 on the side wall of the silo of the mixing device. By providing the connecting pieces 43, it is convenient to connect the elastic limit rope sleeve 42 to the connecting plate 44.

[0020] A connecting plate 44 is fixedly connected to the bottom end of the connecting piece 43. A magnetic adsorption fixing plate 45 is fixedly connected to the inner wall of the connecting plate 44. By providing the connecting plate 44 and the magnetic adsorption fixing plate 45, the connecting cloth 41 and the elastic limit rope sleeve 42 can be limited to prevent the connecting cloth 41 and the elastic limit rope sleeve 42 from detaching from the silo of the mixing device. During installation, the staff magnetically adsorbs and fixedly connects the magnetic adsorption fixing plate 45 to the side wall of the silo of the mixing device. The connecting plate 44 plays an isolating role to prevent the raw materials from being magnetically adsorbed on the magnetic adsorption fixing plate 45.

[0021] The working principle and usage process of the present utility model: The staff adjusts the tail end of the protective slag raw material conveyor belt 1 to the top of the silo of the mixing device. Subsequently, the staff expands the elastic connecting rope sleeve 4 and the elastic limit rope sleeve 42, and slews the two connecting cloths 41 and the elastic limit rope sleeve 42 on both sides of the top of the silo of the mixing device. Then, the elastic connecting rope sleeve 4 and the elastic limit rope sleeve 42 contract under their own elastic forces to contract the connecting cloth 41 on both sides of the silo of the mixing device. Subsequently, the staff magnetically adsorbs and fixedly connects the magnetic adsorption fixing plate 45 to the side wall of the silo of the mixing device. During use, the raw materials are fed into the mixing device by the protective slag raw material conveyor belt 1. After the raw materials are conveyed to the tail end, they are added into the silo of the mixing device under the action of gravity and inertia. During the feeding process of the raw materials, with the help of the support frame 2, the support frame plate 3 and the elastic intercepting cloth 31 cooperate to form a semi-closed space, and the top dense dust-proof hairs 21 and the bottom dense dust-proof hairs 33 cooperate to block the gaps between the support frame 2, the support frame plate 3 and the protective slag raw material conveyor belt 1, which can intercept and protect the space between the protective slag raw material conveyor belt 1 and the stirring device, and prevent the scattered powder from escaping outward to protect the environment of the production workshop.
