Description

Technical Field

[0001] The utility model relates to the technical field of vertical mills, and specifically discloses an energy-saving and environment-friendly vertical mill feeding mechanism. Background Art

[0002] The vertical mill is a grinding equipment that integrates fine crushing, drying, grinding, powder selection and conveying. During the use of the existing vertical mill, once the feed amount in the feed pipe is small, the crushed fine powder will easily flow into the feed pipe with the hot air flow and be discharged to the outside of the vertical mill, resulting in the loss of fine powder and heat. Utility Model Content

[0003] In view of the above-mentioned defects or shortcomings in the prior art, the present application aims to provide an energy-saving and environmentally friendly vertical mill feeding mechanism, comprising a vertical mill body, a discharge pipe arranged at the bottom of the vertical mill body and a feed pipe arranged on one side of the discharge pipe, the interior of the feed pipe is fixedly sleeved with a delivery barrel located on the inner side of the feed pipe by bolts, the interior of the delivery barrel is rotatably connected to a spiral conveying rod, the outer side of one end of the spiral conveying rod extending out of the outside of the delivery barrel is fixedly sleeved with a motor fixedly mounted on the delivery barrel through a shaft sleeve, the outer side of the delivery barrel is connected to the feed barrel, and a limiting mechanism is arranged on the outer side of one end of the delivery barrel extending to the inner side of the feed pipe, and a blocking mechanism is sleeved inside the limiting mechanism.

[0004] Preferably, the limiting mechanism comprises an annular boss arranged on the outside of the conveying cylinder and movably sleeved inside the feeding pipe, the interior of the annular boss is fixedly sleeved with a first limiting rod and a second limiting rod, and a limiting plate is jointly provided on one side of the first limiting rod and the second limiting rod.

[0005] Preferably, a limiting boss is arranged on the outer side of one end of the spiral conveying rod away from the motor, and the limiting rod is fixedly sleeved inside the spiral conveying rod.

[0006] Preferably, the blocking mechanism includes a first guide rod and a second guide rod movably sleeved inside a limit plate, a fixed plate located outside the spiral conveying rod is commonly provided on one side of the first guide rod and the second guide rod, a spring located between the limit plate and the fixed plate is sleeved on the outside of the first guide rod and the second guide rod, a fixed sleeve is rotatably connected inside the fixed disk, and a material blocking plate located outside the feed barrel is provided on one side of the fixed sleeve.

[0007] Beneficial effects:

[0008] 1. The energy-saving and environment-friendly vertical mill feeding mechanism can drive the spiral conveying rod to rotate and convey the raw materials inside the feed barrel at the same time through the drive of the motor. At this time, the raw materials can compress the spring through the baffle plate to open the discharge port of the feed barrel, and when the amount of raw materials inside the feed barrel is reduced, the elastic force of the spring can press the baffle plate to block and seal the discharge port of the feed barrel, so that the crushed fine powder is not easy to be discharged to the outside of the vertical mill through the feed barrel during the flow of hot air, thereby reducing the loss of fine powder and heat.

[0009] 2. The energy-saving and environment-friendly vertical mill feeding mechanism can limit the baffle plate by the limiting boss and make the baffle plate rotate synchronously with the spiral conveying rod. Therefore, in the process of the baffle plate blocking and sealing the discharge port of the feed cylinder, the raw material will not be clamped between the feed cylinder and the baffle plate, ensuring that the feed cylinder and the baffle plate can fit together. The baffle plate can be limited by the limiting rod, so that after the end face of the baffle plate is worn, it will not continue to move under the elastic force of the spring, thereby reducing the wear between the baffle plate and the spiral conveying rod.

[0020] Among them, the limiting mechanism 9 includes an annular boss 91 arranged on the outside of the conveying barrel 5 and movably sleeved inside the feeding pipe 3. The annular boss 91 can block the gap between the feeding pipe 3 and the conveying barrel 5 to prevent fine powder from entering the gap between the two. The internal fixed sleeve of the annular boss 91 is equipped with a first limiting rod 92 and a second limiting rod 93. A limiting plate 94 is jointly arranged on one side of the first limiting rod 92 and the second limiting rod 93. Through the coordinated use of the annular boss 91, the first limiting rod 92, the second limiting rod 93 and the limiting plate 94, the material blocking plate 106 can be stably moved along the axial direction of the first guide rod 101 and the second guide rod 102.

[0021] Among them, a limiting boss 11 is provided on the outer side of the end of the spiral conveying rod 6 away from the motor 7, and the limiting boss 11 can be used to limit and guide the material blocking plate 106, so that the material blocking plate 106 can rotate synchronously with the feeding barrel 5, and the internal fixed sleeve of the spiral conveying rod 6 is provided with a limiting rod 12, and the spiral conveying rod 6 can be limited by the limiting rod 12 to avoid excessive wear of the material blocking plate 106 between the feeding barrel 5 under the elastic force of the spring 104.

[0022] Among them, the blocking mechanism 10 includes a first guide rod 101 and a second guide rod 102 movably sleeved inside the limit plate 94, and a fixed plate 103 located outside the spiral conveying rod 6 is commonly provided on one side of the first guide rod 101 and the second guide rod 102, and a spring 104 located between the limit plate 94 and the fixed plate 103 is mounted on the outer side of the first guide rod 101 and the second guide rod 102, and a fixed sleeve 105 is rotatably connected inside the fixed plate 103, and a blocking plate 106 located outside the feed barrel 5 is provided on one side of the fixed sleeve 105, and the blocking plate 106 can be driven by the elastic force of the spring 104 to block the discharge port of the feed barrel 5, and when the raw material inside the feed barrel 5 is conveyed under the rotation of the spiral conveying rod 6, the raw material can push the blocking plate 106, thereby opening the discharge port of the feed barrel 5, so that the raw material can be conveyed to the inside of the vertical mill body 1.

[0023] When the vertical mill is working, the raw material is transported to the inside of the feed barrel 5 through the feed barrel 8, and the screw conveying rod 6 is driven by the motor 7 to rotate while the raw material inside the feed barrel 5 is gradually transported to the discharge port. As the screw conveying rod 6 continues to rotate, the material pushes the baffle plate 106 and compresses the spring 104 at the same time, and the material is discharged from the discharge port. When the amount of raw material inside the feed barrel 5 is small, the elastic force of the spring 104 can drive the baffle plate 106 to reset. In this process, the rotation of the baffle plate 106 can rotate and crush the raw material sandwiched between the feed barrel 5 and the baffle plate 106 to discharge it, so as to avoid the raw material being sandwiched between the two. At this time, the baffle plate 106 can block the discharge port of the feed barrel 5.
