Description

Technical Field

[0001] The utility model relates to the technical field of molybdenum oxide roasting, in particular to a block material screening and returning device for molybdenum oxide roasting. Background Art

[0002] In the modern preparation process of molybdenum oxide, due to the irregular original size of the molybdenum oxide raw materials and the unstable local internal humidity, some molybdenum oxide cannot be completely turned into powder after roasting and still has agglomeration. Therefore, the agglomerated molybdenum oxide needs to be re-calcined in the furnace.

[0003] At present, after the molybdenum oxide is roasted, it needs to be cooled before screening and retorting. At present, the screening and retorting of molybdenum oxide agglomerates mainly uses a screen bucket to screen the material according to the mesh size. This method is prone to incomplete screening and agglomerates are easy to get stuck in the screen. Furthermore, since the roasting process is mostly a continuous operation, the amount that needs to be screened on one side of the screen plate is also large, and the blocked gap cannot be cleaned in time, which easily causes incomplete screening. In view of this, in-depth research was conducted on the above-mentioned problems, and this case came into being. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides an implementation scheme: in the modern molybdenum oxide roasting process, the product produced by roasting is mostly in powder form. The powder produced by roasting and the agglomerated material are sieved after cooling. However, the current separation device mostly uses a screen separation. Since the continuous roasting produces a lot of materials, it is easy to get blocked during the production process, resulting in incomplete separation.

[0022] In view of the above problems, the present application discloses a device for screening and returning block materials for roasting molybdenum oxide, comprising a material cooling belt 1, which conveys and discharges materials. The material cooling belt 1 conveys and cools the material, and the material is fed to one side of a material discharge trough 2. Under the guidance of the material discharge trough 2, the material enters a separation roller 3. The separation roller 3 is a tubular structure and a plurality of separation holes 4 are provided in an annular array on the separation roller 3. The diameter of the separation holes 4 on the separation roller 3 matches the diameter of the practical material. The separation roller 3 is used to separate and discharge materials. A return-to-furnace reflux structure is installed on the separation roller 3, and the diverted material can be guided and returned to the furnace through the return-to-furnace reflux structure.

[0023] Specifically, the above-mentioned return furnace reflux structure includes a conveyor belt 5, which is arranged at the end of the separation roller 3, and the separation roller 3 has a certain inclination angle with the horizontal. A guide shell 6 is coaxially arranged outside the separation roller 3, and the upper end of the guide shell 6 is connected to the discharge chute 2, and the lower end of the guide shell 6 extends to the conveyor belt 5; the return furnace reflux structure also includes a rolling drive 7, which is arranged on the guide shell 6 and connected to the separation roller 3, and a power component is connected to one side of the rolling drive 7;

[0024] In the specific implementation process, the guide shell 6 is set on the outside of the separation roller 3, and the guide shell 6 and the separation roller 3 are coaxially arranged. On the one hand, the guide shell 6 supports the separation roller 3, and on the other hand, the guide shell 6 wraps the separation roller 3, so that the fine particle powder material separated by the separation roller 3 is discharged from the bottom of the guide shell 6, and a rolling driver 7 is arranged on the separation roller 3. The rolling driver 7 is driven by a power component, and the rolling driver 7 can drive the separation roller 3 to rotate, so that the material can be continuously turned over during the downward process, so as to avoid incomplete separation caused by material accumulation, and small particles After passing through the separation roller 3, the material falls into the guide shell 6, and is then discharged through the discharge port at the bottom of the guide shell 6. The remaining block materials continue to move forward along the separation roller 3 and fall into the conveyor belt 5. The conveyor belt 5 adopts a circulating structure, and the end of the conveyor belt 5 extends to the return port of the rotary kiln and enters the feeder for re-roasting. In order to prevent small-size materials from clogging the separation hole 4 of the separation roller 3, a cleaning sweeper 8 is provided on one side of the rolling drive 7. The cleaning sweeper 8 is in contact with the separation roller 3. The separation hole 4 can be cleaned by the cleaning sweeper 8, thereby pushing the clogged material out of the separation hole 4, thereby achieving the purpose of complete separation.

[0025] As a preferred solution, further, the feed chute 2 is a bucket-shaped structure, and the feed port of the feed chute 2 extends into the separation roller 3. The material transported from the cooling conveyor belt 5 passes through the guidance and collection of the feed chute 2 and enters one side of the separation roller 3.

[0026] As a preferred solution, further, a pair of support seats are provided on the guide shell 6 to support it on the ground, and a fine material discharge port 9 is opened on the bottom surface of the guide shell 6. The guide shell 6 is supported by the pair of support seats, and the fine material discharge port 9 at the bottom of the guide shell 6 can discharge the material.

[0027] As a preferred solution, further, the main body of the rolling driver 7 is an annular plate, and a bearing is provided at one end of the guide shell 6 to contact the rolling driver 7. A driven gear 10 is provided on the rolling driver 7 to connect with the power component. On the one hand, the rolling driver 7 plays a role of limiting installation through the contact with the bearing, and on the other hand, the purpose of power transmission is achieved through the driven gear 10 and the power gear, thereby achieving the purpose of driving the separation roller 3 to rotate.

[0028] As a preferred solution, further, the cleaning sweeper 8 is a rectangular plate with a dense hard bristle structure and is arranged parallel to the separation roller 3 and the bristles are in contact with the separation roller 3, which can effectively clean the separation holes 4 on the separation roller 3.

[0029] As a preferred solution, further, the power assembly includes a power motor 11, a driving rod 12 is connected to the driving end of the power motor 11, and the end of the driving rod 12 is connected to a driving gear 13 that meshes with the driven gear 10. Specifically, a reducer 14 is also arranged between the power motor 11 and the driving rod 12. The power motor 11 drives the reducer 14 to rotate, so that the reducer 14 drives the driving rod 12 to rotate, and the driving gear 13 arranged on the driving rod 12 can mesh with the driven gear 10, so that the driven gear 10 can drive the rolling driver 7 to rotate, so that the rolling driver 7 drives the separation roller 3 to rotate.
