Technical Field

[0001] This utility model relates to a vertical abrasive device, belonging to the technical field of grinding equipment. Background Technology

[0002] When reusing waste materials from demolished old buildings, grinding equipment is needed to grind and crush the waste materials. This crushed waste is then combined with the proportions of raw and auxiliary materials to prepare mortar, thus enabling the reuse of the waste. The traditional method of grinding waste materials is to use a double-roll crusher. However, double-roll crushers produce waste materials with large particle sizes. While some horizontal grinding mills are now available, their worm gear transmission and adjustment are relatively complex, making adjustment inconvenient, and resulting in poor material flow and uneven material distribution.

[0020] Example 1, such as Figures 1 to 2 As shown, this utility model is a vertical abrasive device, including a stationary disc base 14, an abrasive chamber inside the stationary disc base 14, an abrasive shaft 2 inside the abrasive chamber, a drive mechanism connected to the upper part of the abrasive shaft 2, a feed pipe 15 connected to one side of the abrasive chamber, a discharge port at the bottom of the abrasive chamber, a detachable conical abrasive moving disc 8 fixed to the abrasive shaft 2 at the discharge port, an abrasive stationary disc 9 mounted on the stationary disc base 14 on the outer side of the abrasive moving disc 8, an abrasive gap between the abrasive stationary disc 9 and the abrasive moving disc 8, and a detachable cover plate 13 for pressing the abrasive stationary disc 9 at the bottom of the stationary disc base 14, with a discharge pipe 11 connected to the bottom of the cover plate 13.

[0021] In use, the drive mechanism drives the abrasive shaft 2 to rotate, which in turn drives the abrasive moving disk 8 to rotate. The material enters from the feed pipe 15 and then enters the abrasive chamber. Under the action of gravity, it falls into the abrasive gap. In the abrasive gap, the abrasive stationary disk 9 and the abrasive moving disk 8 cooperate to perform abrasion. After the abrasion is completed, the material falls into the discharge pipe 11 and is discharged. The whole abrasive process is smoother, and the particle size of the abrasive can be adjusted by removing the cover plate 13 and replacing the abrasive stationary disk 9 and the abrasive moving disk 8.

When the abrasive stationary disk 9 is installed, the top of the abrasive stationary disk 9 is inserted into the embedding recess, and then the limiting flange is embedded into the limiting recess for support installation.

[0024] The discharge pipe 11 is a bent pipe, and the lower end of the bent pipe is connected to an outlet short-connecting hose 12. The feed pipe 15 is connected to an inlet short-connecting hose 16. The outlet short-connecting hose 12 and the inlet short-connecting hose 16 are made of rubber, so that the discharge pipe 11 can be removed without removing the cover plate 13, which is more convenient and faster.

[0025] The top of the feed sleeve 7 is provided with a bushing 6 that fits onto the abrasive shaft 2. The top of the abrasive chamber is provided with a sealing port, and a packing box 5 that fits onto the bushing 6 is fixed inside the sealing port. The packing box 5 is provided with sealing packing 26, and the bottom of the sealing packing 26 is provided with a PTFE sleeve 25. The top of the sealing packing 26 is provided with a packing gland 23 that is fixed onto the packing box 5. The PTFE sleeve 25 is made of polytetrafluoroethylene material.

The packing box 5 has a water injection hole that connects to the sealing water ring 24. Before use, water at a certain pressure can be injected into the sealing water ring 24 through the water injection hole for better sealing.

[0027] The top of the stationary disc 14 is bolted to a bearing housing 4, which has a bearing cavity. A bearing supporting the abrasive shaft 2 is installed inside the bearing cavity. A bearing cover 21 is provided at the bottom of the bearing. The drive mechanism includes a drive motor 1 fixed to the top of the bearing housing 4. The output shaft of the drive motor 1 is connected to the top of the abrasive shaft 2 through a coupling sleeve 3. The drive motor 1 can be easily disassembled for maintenance.

[0028] A bearing sleeve 20 is provided below the inner ring of the bearing and fits onto the abrasive shaft 2. A limiting nut 22 is provided at the bottom of the bearing sleeve 20. Oil seals 19 are provided between the bearing cover 21 and the bearing sleeve 20, and between the upper part of the bearing cavity and the abrasive shaft 2. After the bearing is installed, the bearing sleeve 20 can be used to press the inner ring of the bearing, and then the limiting nut 22 can be used to press the bearing sleeve 20.

[0029] The bearing cavity above the bearing is connected to an oil nozzle, and the top of the feed pipe 15 is provided with a flushing port 27. During flushing, high-pressure water can be introduced into the flushing port 27 for flushing.

[0030] A fixing plate 18 is fixed to the top outer side of the bearing housing 4, and a support frame 17 is fixed to the bottom outer side of the fixing plate 18. The support frame 17 can be used for the concrete pouring and installation of the box structure.
