detailed description

The following is a detailed description of the embodiments of the present utility model. This embodiment is implemented on the premise of the technical solution of the present utility model, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present utility model is not limited to the following the described embodiment.

Referring to Fig. 1, this embodiment discloses a scattered sand recovery system in investment casting production, the recovery system is used in conjunction with the sand shower device in investment casting production, wherein the sand shower device includes sequentially arranged from top to bottom Prepare the sand bucket 5, the mobile feeding car 6 and the sand shower storage bin 7.

The recovery system includes a sand receiving bucket 1, a vibrator 4, a conveyor belt 11, a vibrating screening machine 2 and a pneumatic conveying system 3. The sand receiving bucket 1 is located directly below the sand shower storage bin 7 of the sand shower device, and the sand to be showered The workpiece 8 is located between the sand shower storage bin 7 and the sand receiving hopper 1, the vibrator 4 is arranged outside the sand receiving hopper 1, the conveyor belt 11 is arranged under the sand receiving hopper 1, and one end of the conveyor belt 11 is located in the sand receiving hopper 1 Just below the outlet of the vibrating screen machine, the other end is docked with the inlet of the vibrating screen machine 2, the pneumatic conveying system 3 is set directly below the outlet of the vibrating screen machine 2, and the outlet of the pneumatic conveying system 3 passes through the conveying pipeline and multiple sand preparations of the sand shower device Bucket 5 is connected. The pneumatic conveying system 3 recovers the scattered sand to the sand preparation hopper 5 of the sand shower device through pneumatic force, and strictly distinguishes the unmixed materials.

The conveying pipeline includes a main pipeline 9 and a plurality of sub-pipes 10 . The sub-pipes 10 are located above the sand preparation hoppers 5 in one-to-one correspondence, and the sub-pipes 10 communicate with the corresponding sand preparation hoppers 5 and the main pipeline 9 .

During operation, first add sand material to multiple sand preparation hoppers 5, quantitatively feed material into the sand shower storage bin 7 by moving the feeding truck 6, and then open the sand shower storage bin 7 to perform sand shower operation on the workpiece 8 below, The scattered sand in the sand shower process is collected by the sand receiving bucket 1 arranged under the workpiece 8, and the scattered sand in the sand receiving bucket 1 automatically falls on the conveyor belt 11 below under the vibration of the vibrator 4, and It is transported to the vibrating screening machine 2 through the conveyor belt 11, and the sand cluster formed by mixing sand particles and slurry is screened and removed from the scattered sand by the vibrating screening machine 2, and transported to the designated place. The vibrating screening machine 2 conveys the screened scattered sand to the pneumatic conveying system 3, and then recycles and distributes different types of scattered sand to each corresponding sand preparation hopper 5 through the conveying pipeline for classification and recovery, and is used as a sand shower again. Spare sand. Wherein the vibrator 4 can vibrate all the sand in the sand receiving bucket 1 to avoid residual sand mixing. During the collection, transportation, and storage of the entire recycling system, all kinds of scattered sand are not mixed and are strictly separated.

The above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model should be included in the utility model. within the scope of protection.
