Description

Technical Field

[0001] The utility model belongs to the technical field of part replacement mechanisms, and in particular relates to a wear-resistant part replacement mechanism for a resin sand regenerator. Background Art

[0002] Resin sand regenerators are generally used in supporting resin sand production lines, and can also be used as a single machine for crushing. The first-level regeneration of resin sand generally uses a multifunctional vibration crushing regenerator, which mainly crushes large pieces of sand and rubs them to remove the film. The second-level regeneration generally uses centrifugal regeneration, which is mainly mechanical rubbing. Through strong centrifugal action, the resin film on the surface of the sand is removed. The sand blocks are rubbed and rubbed against each other in the resin sand centrifugal regenerator, and then basically form sand particles and a small number of tiny sand blocks. The small sand blocks in the old sand after crushing are removed by screening. The old sand after screening basically exists in the form of sand particles and then enters the rotor regenerator. In the rotor regenerator, the sand passes through the rapidly rotating blades, so that the sand flow that has just entered the top of the regenerator is immediately thrown to the wear-resistant cylinder wall under the action of centrifugal force, so that the old sand rubs against each other in the regenerator, and the residual adhesive film on the surface of the sand particles is removed by impact. The old sand regenerated by the regenerator contains a large amount of dust and particles. The presence of these substances will seriously affect the performance of the resin. Therefore, it must be cleaned by air selection. The regenerated sand after air separation can be transported to the sand storage for storage, cooling and standby use.

[0003] The existing regeneration mechanism has a small internal space and heavy wear parts. The replacement of wear parts basically relies on manual handling and replacement, which has high labor intensity and is extremely inconvenient to operate. As a result, many users have not replaced the wear parts of the regeneration machine for many years, and thus cannot obtain high-quality regenerated sand. In the end, they have to purchase a large amount of new sand to meet the use requirements of castings, which greatly increases production costs. In addition, all equipment manufacturers in the industry do not provide a replacement mechanism to solve the problem of difficulty in replacing wear parts. Utility Model Content

[0004] The utility model aims to provide a wear-resistant part replacement mechanism for a resin sand regenerator, which greatly reduces the labor intensity and difficulty of replacing wear-resistant parts, and the replacement process is simple to operate, thereby saving manpower and replacement time.

[0006] Preferably, the wear-resistant parts include a sand guide cone, a wear-resistant retaining ring, and a wear-resistant rotor disk; the wear-resistant rotor disk is arranged at the bottom of the wear-resistant retaining ring, and the sand guide cone is arranged inside the wear-resistant rotor disk through mounting bolts.
