Description
本發明係有關於一種回收結構,尤指一種用以將鑄造後之鑄造廢砂粉碎細粒化的鑄造廢砂回收結構。 The present invention relates to a recycling structure, in particular to a recycling structure for waste foundry sand used for pulverizing and finely granulating waste foundry sand after casting.
按,鑄造是指將金屬加熱後變成熔融的金屬液體,在熔融狀態時將其倒入預先做好的鑄模內,待其冷卻凝固後取出,除去澆冒口等,即得所需之鑄件,而鑄模的材料大多是鑄砂,故亦稱為砂模,該砂模在一次性的使用完畢後,因為經過鑄造後其狀態會有所改變,鑄砂會因高溫燒結成塊狀,因而回收鑄砂時通常會將砂模打碎形成碎塊狀,去除充當粘結劑使用之樹脂或皂土等雜質,再使用一粉碎機利用高速旋轉之離心力將碎塊狀鑄砂粉碎成顆粒狀。 Press, casting refers to heating the metal into a molten metal liquid, pour it into a pre-made mold when it is in a molten state, and take it out after cooling and solidification, remove the pouring riser, etc., to obtain the desired casting. Most of the material of the casting mold is sand casting, so it is also called sand mold. After the one-time use, the state of the sand mold will change after casting. The casting sand will be sintered into lumps due to high temperature, so it is recycled. When casting sand, the sand mold is usually broken into pieces to remove impurities such as resin or bentonite used as a binder, and then a pulverizer is used to pulverize the broken pieces of casting sand into granules using the centrifugal force of high-speed rotation.
然而,該粉碎機係利用高速旋轉之離心力,帶動碎塊狀鑄砂反覆撞擊粉碎機內壁達到逐漸粉碎的效果,故易造成粉碎機內壁磨耗,以致粉碎機容易損壞,而需時常維修或更換零組件,另外,該種方式撞擊的機率低,使得粉碎效率差,粉碎的效果有限,無法達到確實的細化效果。 However, the crusher uses the centrifugal force of high-speed rotation to drive the fragmented cast sand to repeatedly hit the inner wall of the crusher to achieve a gradual crushing effect. Therefore, the inner wall of the crusher is easily worn, and the crusher is easily damaged and requires frequent maintenance or repair. Replacement of components, in addition, the probability of impact in this way is low, resulting in poor crushing efficiency, limited crushing effect, and no real refinement effect.
本發明人有鑑於習知鑄砂粉碎機具有上述缺點,是以乃思及創作的意念,經多方探討與試作樣品試驗,及多次修正改良後,終推出本發明。 In view of the above-mentioned shortcomings of the conventional sand pulverizer, the inventor finally came up with the present invention after many discussions, trial sample tests, and many modifications and improvements based on the idea of thinking and creation.
本發明提供一種鑄造廢砂回收結構,包含:一送風單元,該送風單元包括有一氣壓裝置及複數送風管,該複數送風管與該氣壓裝置連通,由該氣壓裝置產生高壓空氣輸出至該複數送風管;一粉碎單元,該粉碎單元具有一進砂端及一出砂端,該進砂端與出砂端間設有以複數分隔部分隔形成之複數粉碎區,該分隔部設有連通相鄰粉碎區之至少一流通孔,各粉碎區分別設有一粉碎進風孔與該複數送風管組接,再者,至少最靠近該進砂端的粉碎區設有一進砂孔,該出砂端設有至少一出砂孔與最靠近該出砂端的粉碎區連通;及一回收單元,該回收單元與該粉碎單元之出砂端連接,該回收單元包括有一回收空間、一出風口及一排砂口,該回收空間與該粉碎單元之出砂孔連通,該出風口及該排砂口分別與該回收空間連通。 The present invention provides a foundry waste sand recovery structure, comprising: an air supply unit, the air supply unit includes an air pressure device and a plurality of air supply pipes, the plurality of air supply pipes are connected with the air pressure device, the air pressure device generates high-pressure air output to the plurality of air supply Tube; a crushing unit, the crushing unit has a sand inlet and a sand outlet, the sand inlet and the sand outlet is provided with a plurality of divided parts separated by a plurality of pulverization zone, the partition is provided with adjacent adjacent At least one flow hole in the crushing zone, each crushing zone is provided with a crushing air inlet hole to connect with the plural air supply pipes, and at least the crushing zone closest to the sand inlet is provided with a sand inlet, and the sand outlet is provided with At least one sand outlet is connected to the crushing zone closest to the sand outlet; and a recovery unit connected to the sand outlet of the crushing unit.

本發明鑄造廢砂回收結構之主要目的,在於其係將鑄造廢砂持續送入粉碎單元靠近進砂端的粉碎區內,及由送風單元產生高壓空氣經過複數送風管輸送至粉碎單元之各粉碎區內,於各粉碎區內產生漩渦氣流,利用該漩渦氣流帶動鑄造廢砂在各粉碎區內翻滾,令鑄造廢砂撞擊粉碎區內壁及於粉碎區內相互撞擊,並且同時令鑄造廢砂由粉碎單元靠近進砂端的粉碎區通過分隔部的流通孔逐一往靠近出砂端的粉碎區移動,使得鑄造廢砂逐漸粉碎,藉以達到粉碎過程機械磨損大幅降低,粉碎效率及粉碎效果提升。 The main purpose of the foundry waste sand recovery structure of the present invention is to continuously send the foundry waste sand into the crushing area near the sand inlet end of the crushing unit, and the high-pressure air generated by the air supply unit is transported to the crushing areas of the crushing unit through multiple air supply pipes. Inside, a vortex air current is generated in each crushing zone, and the vortex air current is used to drive the waste foundry sand to roll in each crushing zone, so that the waste foundry sand hits the wall of the crushing zone and collides with each other in the crushing zone, and at the same time, the waste foundry sand is removed The crushing area of the crushing unit near the sand inlet end moves one by one to the crushing area near the sand outlet through the circulation hole of the partition, so that the waste foundry sand is gradually crushed, so that the mechanical wear of the crushing process is greatly reduced, and the crushing efficiency and crushing effect are improved.
