Description

Technical Field

[0001] This utility model relates to the technical field of metal recycling equipment, and in particular to a metallurgical solid waste recycling device. Background Technology

[0002] Scrap metal refers to metal fragments and scraps discarded by the metallurgical and metal processing industries, as well as metal objects scrapped from equipment upgrades. Solid waste refers to solid and semi-solid items generated during production, daily life, and other activities that have lost their original utilization value or have been discarded or abandoned even if they have not lost their utilization value. To avoid solid waste from polluting the environment, it is necessary to carry out unified treatment on a regular basis.

[0003] When treating solid waste, larger metallurgical solid waste usually needs to be crushed and screened to obtain usable particles. Screening is usually done using sieves to classify the crushed solid waste and recycle the recyclable solid waste. However, because the sieves are installed in a fixed manner, the screening process can be clogged due to the presence of large solid waste, resulting in low screening and recycling efficiency. Utility Model Content

[0004] In view of the problems that existing waste metal powder classification and recycling processes are prone to clogging of mesh holes and powder blockage of discharge ports during powder screening, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a metallurgical solid waste recycling device, the purpose of which is: the waste metal recycling powder screening equipment can clean up blocked holes, and the metal powder is easy to accumulate at the bottom of the screening equipment and cannot be discharged.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a metallurgical solid waste recycling device, including a waste metal powder classifier, wherein a screening mechanism is fixedly installed in the inner cavity of the waste metal powder classifier, and a storage and discharge mechanism is fixedly installed at the bottom of the inner cavity of the waste metal powder classifier.

[0007] The screening mechanism includes a fixed frame, the outer surface of which is fixedly connected to the inner surface of the waste metal powder classifier, and a screening pipe network is fixedly installed on the inner surface of the fixed frame.

[0008] In a preferred embodiment of the metallurgical solid waste recycling device of this utility model, the screening mechanism further includes a motor, the outer surface of which is fixedly connected to the outer surface of the waste metal powder classifier via a connecting frame, a rotating shaft is fixedly installed at the output end of the motor via a reducer, a rotating frame is fixedly installed on the outer surface of the rotating shaft, an inclined rod is fixedly installed on the outer surface of the rotating frame, and a cleaning brush is fixedly installed on the outer surface of the inclined rod.

[0009] As a preferred embodiment of the metallurgical solid waste recycling device of this utility model, the screening mechanism further includes a feed pipe and a discharge port. The left end of the feed pipe passes through the waste metal powder classifier and extends into the interior of the waste metal powder classifier. The discharge port is opened through the outer surface of the screening pipe network.

[0010] In a preferred embodiment of the metallurgical solid waste recycling device of this utility model, the storage and discharge mechanism includes a guide frame, the outer surface of which is fixedly connected to the inner surface of the waste metal powder classifier.

[0011] As a preferred embodiment of the metallurgical solid waste recycling device of this utility model, the storage and discharge mechanism further includes a first connecting rotating frame, the bottom of which is fixedly connected to the bottom of the inner cavity of the waste metal powder classifier, a cylinder is fixedly installed on the outer surface of the first connecting rotating frame, a piston rod is fixedly installed on the output end of the cylinder, and a second connecting rotating frame is fixedly installed on the top end of the piston rod.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] 1. This utility model improves upon the design of preventing clogging of the holes in the waste metal powder screening equipment by adding a design to prevent clogging. Through the combined use of the motor and rotating shaft with the rotating frame and inclined rod, and the combined use of the inclined rod and cleaning brush with the screening pipe network, the metal powder can be screened in multiple stages, and the blocked holes in the screening pipe network can be cleaned. This avoids the problem of low screening and recycling efficiency caused by clogging due to the presence of large amounts of fixed waste during the screening process.

[0016] 2. This utility model improves the design by adding a feature to facilitate the smooth discharge of powder accumulated during screening. This is achieved through the coordinated use of the waste metal powder sorter and guide frame with the first connecting rotating frame and cylinder, the coordinated use of the cylinder and air rod with the second connecting rotating frame and feeding plate, and the coordinated use of the feeding plate and waste metal powder sorter with the discharge rack and baffle plate. This ensures that the metal powder is kept in a sealed state during screening, while simultaneously moving the powder accumulated on the feeding plate forward and discharging it from the discharge rack, thus avoiding the problem of metal powder accumulation and obstruction.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0024] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a metallurgical solid waste recycling device. The metallurgical solid waste recycling device includes a waste metal powder classifier 1, a screening mechanism 2 is fixedly installed in the inner cavity of the waste metal powder classifier 1, and a storage and discharge mechanism 3 is fixedly installed at the bottom of the inner cavity of the waste metal powder classifier 1.

[0025] The screening mechanism 2 includes a fixed frame 21, the outer surface of which is fixedly connected to the inner surface of the waste metal powder classifier 1, and a screening pipe network 22 is fixedly installed on the inner surface of the fixed frame 21.

[0026] The screening mechanism 2 also includes a motor 23. The outer surface of the motor 23 is fixedly connected to the outer surface of the waste metal powder classifier 1 through a connecting frame. The output end of the motor 23 is fixedly mounted with a rotating shaft 24 through a reducer. A rotating frame 25 is fixedly mounted on the outer surface of the rotating shaft 24. An inclined rod 26 is fixedly mounted on the outer surface of the rotating frame 25. A cleaning brush 27 is fixedly mounted on the outer surface of the inclined rod 26.

[0027] The screening mechanism 2 also includes a feed pipe 28 and a discharge port 29. The left end of the feed pipe 28 passes through the waste metal powder classifier 1 and extends into the interior of the waste metal powder classifier 1. The discharge port 29 passes through the outer surface of the screening pipe network 22.

[0028] During use, the motor 23 drives the rotating shaft 24 to rotate, and the rotating shaft 24 drives the inclined rod 26 to rotate through the rotating frame 25. The inclined rod 26 drives the metal powder to rotate and move within the screening tube network 22. At the same time, the cleaning brush 27 on the inclined rod 26 cleans out the metal powder stuck on the screening tube network 22. After being screened by different sized holes on the screening tube network 22, the metal powder falls below and is guided inward by the guide frame 31 to the feeding plate 37. Example 2

[0029] Reference Figure 1 and Figure 4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the storage and discharge mechanism 3 includes a guide frame 31, and the outer surface of the guide frame 31 is fixedly connected to the inner surface of the waste metal powder classifier 1.

[0030] The storage and discharge mechanism 3 also includes a first connecting rotating frame 32. The bottom of the first connecting rotating frame 32 is fixedly connected to the bottom of the inner cavity of the waste metal powder classifier 1. A cylinder 33 is fixedly installed on the outer surface of the first connecting rotating frame 32. A piston rod 34 is fixedly installed at the output end of the cylinder 33. A second connecting rotating frame 35 is fixedly installed at the top of the piston rod 34.

[0031] The storage and discharge mechanism 3 also includes a rotating rod 36, both ends of which are rotatably connected to the inner surface of the waste metal powder classifier 1. A feeding plate 37 is fixedly installed on the outer surface of the rotating rod 36, and the bottom of the feeding plate 37 is fixedly connected to the top of the second connecting rotating frame 35.

[0032] The storage and discharge mechanism 3 also includes a discharge rack 38, the back of which is connected to the front of the waste metal powder classifier 1, and a baffle plate 39 is slidably installed on the inner surface of the discharge rack 38.

[0033] During use, the metal powder is screened by different apertures on the screening pipe network 22 and falls below. It is then guided inward by the guide frame 31 to the feeding plate 37. After the powder has been screened for a period of time, the user first puts the storage bag on the discharge rack 38, then opens the baffle 39. Then, the cylinder 33 drives the second connecting rotating frame 35 to move upward through the air rod 34. The second connecting rotating frame 35 drives the feeding plate 37 to rotate around the rotating rod 36, moving the metal powder accumulated on the feeding plate 37 from the discharge rack 38, so that the metal powder can be discharged from the discharge rack 38.

[0034] The remaining structure is the same as that in Example 1.

[0035] Based on embodiments 1-2, the working principle of this utility model is as follows: The pulverized non-metallic powder is fed into the screening network 22 within the waste metal powder classifier 1 through the feed pipe 28. Then, the rotating shaft 24 is driven to rotate by the motor 23. The rotating shaft 24 drives the inclined rod 26 to rotate via the rotating frame 25. The inclined rod 26 causes the metal powder to rotate and move within the screening network 22. Simultaneously, the cleaning brush 27 on the inclined rod 26 cleans out any metal powder stuck on the screening network 22. The metal powder passes through the screening network 22... After being screened by different sized apertures, the powder falls to the bottom and is guided inward by the guide frame 31 to the feeding plate 37. After the powder has been screened for a period of time, the user first puts the storage bag on the discharge rack 38, then opens the baffle 39, and then the cylinder 33 drives the second connecting rotating frame 35 to move upward through the air rod 34. The second connecting rotating frame 35 drives the feeding plate 37 to rotate around the rotating rod 36, moving the metal powder accumulated on the feeding plate 37 from the discharge rack 38, so that the metal powder can be discharged from the discharge rack 38.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
