Description
Technical Field
[0001] This utility model relates to the field of vertical mill technology, and in particular to a water supply device for a vertical mill. Background Technology
[0002] Vertical mills, as a high-efficiency fine grinding equipment and technology introduced in recent years, have been widely used in metallurgy, mineral processing, chemical industry, cement, ceramics, construction, power and defense industries. In particular, vertical mills play a very important role in the mineral processing of the metallurgical industry. The processing capacity and particle size of the vertical mill have a significant impact on the efficiency of subsequent operations and the technical and economic indicators of the overall production process.
[0003] A search revealed a publication (announcement) number: CN206560910U, which discloses a stable water supply device for a vertical mill of mineral powder. The water nozzle is installed at the mill's feed inlet and has a ring-shaped structure with multiple spray holes evenly distributed around its circumference. The outer diameter of the ring matches the diameter of the inner wall of the mill's feed inlet. The ring is fixed to the inner wall of the feed inlet, and the water spray direction is obliquely downwards. This invention changes the water nozzle from a traditional sprinkler to a ring-shaped structure, reducing clogging and ensuring more even mixing of water and slag, resulting in a more stable material layer inside the mill and more stable mill operation. This invention also changes the water supply location by installing the nozzle at the mill's feed inlet, changing the water supply from inside to outside the mill. The nozzle can be easily disassembled, avoiding downtime for repairs, simplifying maintenance, and reducing production costs.
[0004] Although the above solution changes the water spraying position of the water adding device by installing the water spray nozzle at the feed inlet of the vertical mill, changing the original in-mill water adding to external water adding, and the water spray nozzle can be disassembled at any time to avoid downtime for repairs and make maintenance convenient, the water is added from top to bottom, and cannot be evenly added according to the amount of powder in the vertical mill. Therefore, we propose a water adding device for vertical mills. Utility Model Content
[0005] The main purpose of this utility model is to provide a water supply device for a vertical mill, which solves the problem of uniformly injecting water according to the amount of powder in the vertical mill by setting up a lifting unit and a water supply unit.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A water supply device for a vertical mill includes a lifting unit, a water supply unit disposed on the side of the lifting unit, and a water storage unit disposed above the lifting unit.
[0008] The lifting unit includes a C-shaped base, a threaded shaft movably disposed inside the C-shaped base, a movable component disposed on the threaded shaft, and a drive motor installed at the input end of the threaded shaft.
[0009] The water supply unit includes a water distribution tank installed on the side wall of the moving part, a water distribution pipe installed at the bottom of the water distribution tank, and a water supply nozzle installed on the side wall of the water distribution pipe.
[0010] Preferably, the movable component includes a movable seat mounted on the circumferential side of the threaded shaft, and a connecting rod mounted between the movable seat and the water distribution tank.
[0011] Preferably, the lifting unit further includes a limiting washer installed on the inner side wall of the U-shaped seat, and the limiting washer is sleeved on the circumferential side of the threaded shaft.
[0012] Preferably, there are several groups of water-filling nozzles, and the several groups of water-filling nozzles are arranged at equal intervals.
[0013] Preferably, the water storage unit includes a fixed base installed on the side wall of the U-shaped base, a water storage component disposed above the fixed base, an output component disposed on the side of the water storage component, and a delivery pipe disposed between the output component and the water distribution tank.
[0014] Preferably, the water storage component includes a water tank installed on top of the fixed base, a water inlet opened on top of the water tank, and a sealing plug installed inside the water inlet.
[0015] Preferably, the output component includes an output pipe installed on the side wall of the water tank, and a regulating valve movably installed inside the output pipe.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] In this invention, through the lifting unit and water supply unit, when water needs to be added according to the amount of powder in the vertical mill, the drive motor drives the threaded shaft. At this time, the moving part drives the water distribution tank to move up and down along the threaded shaft until the water distribution pipe is inserted into the powder in the vertical mill and then stops. This achieves the adjustment of the insertion depth of the water supply rod inside the vertical mill according to the amount of powder in the vertical mill. After the water supply rod is deeply inserted into the powder in the vertical mill, the regulating valve is opened. At this time, the water in the water storage tank is transported to the water distribution tank through the conveying pipe, and the water is evenly sprayed onto the powder in the vertical mill through the water supply nozzle on the side of the water distribution pipe, thus achieving uniform water injection according to the amount of powder in the vertical mill.

The setting of the limiting washer 105 avoids the moving seat 1031 from contacting and colliding with the inner side wall of the C-shaped seat 101 during the up and down movement along the threaded shaft 102.
[0033] like Figure 3 As shown, there are several groups of water injection nozzles 203, and these groups of water injection nozzles 203 are arranged at equal intervals, thereby enabling uniform water injection into the powder.

[0036] When water needs to be added according to the amount of powder in the vertical mill, the drive motor 104 drives the threaded shaft 102. At this time, the moving part 103 drives the water distribution tank 201 to move up and down along the threaded shaft 102 until the water distribution pipe 202 is inserted into the powder in the vertical mill and then stops. This realizes the adjustment of the insertion depth of the water supply rod inside the vertical mill according to the amount of powder in the vertical mill. Example 2
