Description
본 발명은 표면에 수용성 접착제가 묻어 응고되어 있는 폐주물사에서 수용성 접착제를 제거하고 주물사를 다시 사용할 수 있게 세척하는 주물사의 재생방법 및 그 장치에 관한 것으로 보다 구체적인 것은 폐주물사를 분쇄하여 수세통내에 넣고 물과 같이 교반하여 주물사에 묻어 있는 수용성 접착제인 규산나트륨접착제를 제거하고 응고된 주물사를 분쇄하여 다시 사용할 수 있게 씻어 깨끗한 상태의 주물사를 얻을 수 있게 하는 것이다.The present invention relates to a method for regenerating foundry sand and a device for removing the water-soluble adhesive from the solidified waste foundry sand with the water-soluble adhesive solidified on the surface thereof, and washing the foundry sand for reuse. By stirring together, the sodium silicate adhesive, which is a water-soluble adhesive on the foundry sand, is removed, and the solidified foundry sand is pulverized and washed again to obtain a clean foundry sand.
종래에는 폐주물사를 회전통 속에 넣고 회전통을 고속회전시켜서 폐주물사가 회전통내에서 원심력을 받아 회전통내에서 서로 부딪치게 하여 폐주물사를 분쇄하고 그 표면에 묻은 규산나트륨이 분리되게 한 다음 바람을 공급하여 주물사와 접착제를 분리시키는 방법으로 주물사를 재생하여 사용하고 있다.Conventionally, the waste casting sand is placed in a rotating cylinder and the rotating cylinder is rotated at a high speed so that the waste casting yarns are subjected to centrifugal force in the rotating cylinder and collide with each other in the rotating cylinder to crush the waste casting sand, so that the sodium silicate on the surface is separated, and then supply the casting sand The foundry sand is recycled and used as a method of separating the adhesive from the adhesive.
그러나 이러한 방법은 폐주물사들이 회전통내에서 마찰될때 충돌에 의거 먼지가 많이 발생할 뿐 아니라 선별과정에서도 먼지가 많이 나서 작업이 난이하고 주물사와 접착제가 깨끗이 분리되지 않아서 품질이 떨어지는 등의 불편이 있었다.However, in this method, when the waste foundry sands are rubbed in the rotating barrel, not only dust is generated by the collision but also there is a lot of dust during the sorting process, which makes the operation difficult and the quality of the casting sand and the adhesive is not separated cleanly.
본 발명은 위와 같은 종래의 불편을 해결하기 위해 발명된 것으로 수세통을 이용하여 재생하는 방법에 있으며 또한 본 발명의 목적은 수세방법을 보다 능률적으로 달성하는 것에 있고 아울러 작업환경을 좋게 하고 폐주물사의 회수능률을 높이는 것에 있으며 품질이 좋은 주물사를 얻는 것에 있다.The present invention has been invented to solve the conventional inconveniences as described above in the method of regenerating using a water bottle, and the object of the present invention is to more efficiently achieve the water washing method and to improve the working environment and recovery of waste foundry sand. It's about increasing efficiency and getting quality casting sand.

이를 보다 상세히 설명하면 다음과 같다.This will be described in more detail as follows.
본 발명은 쉘모울드를 분쇄하여 얻어지는 폐주물사를 모아 처리통(3) 속에 투입하고 물을 공급하면서 물과 폐주물사를 일정시간 동안 서서히 교반시키므로서 폐주물사의 표면에 붙어 있는 수용성 접착제를 용해시켜 제거하면서 주물사를 해체시킨 다음 알갱이 상태의 폐주물사를 미세배출구(3a)로 배출시켜 샤워장치와 이송스크류가 장치된 이송홈에 낙하시키고 이송홈통에서 일정의 거리를 이송시키면서 마찰과 샤워를 실시하여 주물사의 표면에 붙어 있는 접착성분을 완전히 제거하고 깨끗한 주물사를 얻어 건조시키므로서 다시 사용할 수 있는 주물사가 되게 한 것이며 이를 위해 본 발명의 처리통(3)에는 급수관(8)이 상부에 장치되어 있고 중심부에 전동 회전축(4)이 설치되어 그 양측으로 지지아암(5)이 돌출되고 교반날개(6)(6a)가 부착되며 일측으로 또 하나의 지지아암(5a)을 장치하여 분쇄로울러(7)를 설치하였으며 바닥일측으로 미세배출구(3a)가 형성되어 그 밑에 개폐판(3b)이 장치는 구성으로 되어 있다.The present invention collects the waste molding sand obtained by pulverizing the shell mold and put it into the processing tank (3) and while stirring the water and the waste casting sand for a predetermined time while supplying water while dissolving and removing the water-soluble adhesive adhered to the surface of the waste casting sand After dismantling, the granulated waste casting sand is discharged to the fine discharge port 3a, and dropped into the transfer groove equipped with the shower device and the transfer screw, and friction and showering are carried out while transferring a predetermined distance from the transfer groove. Completely remove the adhesive component and obtain a clean foundry sand to dry it to be used again to be a sand casting sand for this purpose, the water treatment pipe (3) of the present invention is equipped with a water supply pipe (8) at the top and the electric rotary shaft (4) in the center Is installed so that the supporting arm 5 protrudes on both sides thereof, and the stirring blades 6 and 6a are attached to one side thereof. Also installed was a grinding roller (7) to the device a support arm (5a) is formed with a fine discharge port (3a) to one side of the bottom plate below the opening (3b) This device has a structure.
그리고 이송홈통(9)는 투입부(9a)가 낮고 배출구(9b)가 높은 경사홈으로 형성하여 내부에 이송스크류(10)가 내장되며 이송스크류는 전동장치(M)에 의하여 구동되게 설계되고 이송홈의 상단에서 하측으로 분사되게 샤워기(11)가 장치되는 구성이며 이러한 이송홈통은 1 단계 내지 2 단계로 설치하여 사용되는 것이 바람직하다.In addition, the feed trough 9 is formed with an inclined groove having a low input part 9a and a high discharge port 9b, so that the feed screw 10 is embedded therein, and the feed screw is designed to be driven by the transmission device M. The shower 11 is configured to be sprayed downward from the upper end of the groove is such a transfer gutter is preferably used to install in one to two stages.
한편 처리된 주물사는 건조실(12)에 투입되어 열풍과 같은 강제 건조 장치를 통해 재생품으로 완성이 되는 것이다.Meanwhile, the treated casting sand is put into the drying chamber 12 to be completed as a regenerated product through a forced drying device such as hot air.
이와 같이 제조되는 본 발명의 폐주물사는 주물사로 쉘모울드를 만들때 사용된 수용성 접착제(예 : 규산 소-다 접착제)를 물로 용해하여 제거하는 것이므로 재생과정에서 분진이 발생하지 않는 특징이 있고 처리된 물은 폐수정화장치에서 정화시키면 되므로 환경오염이 없는 간편한 작업이 능률적으로 되는 장점이 있고 폐주물사의 회수율이 높은 이점이 있으며 청결한 주물사를 얻을 수 있는 장점이 있다.The waste foundry sand of the present invention prepared as described above dissolves and removes the water-soluble adhesive (for example, sodium silicate-adhesive adhesive) used when making the shell mold with water, so that no dust is generated during the regeneration process. Since there is an advantage that the simple operation without the environmental pollution can be efficiently streamlined by the waste water purification device, the recovery rate of the waste foundry sand is high, and there is an advantage that a clean foundry sand can be obtained.
한편 본 발명의 처리장치는 폐주물사를 저장통(1)에 모아서 컨베이어장치(2) 등을 통해 처리통(3)으로 투입하고 물을 주입하여 처리통(3)내에서 물과 같이 교반하면 모래가 흡수하면서 그 표면에 묻어 있는 수용성 접착제가 녹아 분리되게 되고 지지아암의 측방으로 장치된 또 하나의 지지아암(5a)에 분쇄로울러(7)가 장치되어 따라 회전하면서 그 진행로 상에 있는 폐주물사의 뭉치를 분쇄하는 작용도 하므로 폐주물사의 분쇄와 동시에 접착제의 용해처리가 이루어지게 되는 이점이 있고 처리통(3)의 바닥에 뚫어진 미세배출구(3a)는 미세하여 덩어리진 폐주물사는 낙하되지 못하고 미세한 처리물과 낙하되도록 되어 있고 저부에 개폐판(3b)이 있으므로 처리통내의 처리시간을 관리하여 개폐판(3b)을 개폐하면서 적절하게 분리가 가능케되며 처리물의 낙하와 처리할 폐주물사의 투입을 연속적으로 실시할 수 있고 개폐판(3b)을 항상 열어 높아도 미세한 배출구(9b)로 인해 처리통내에서 미분되어 접착제가 일부 용해 된 처리물이 처리통 외부로 흘러내려 이송홈통(9)으로 낙하될 수 있고 이송홈통에 낙하된 처리물은 이송스크류(10)에 의하여 경사진 홈통을 거슬러 이동하는 과정을 거치게 되는데 이 과정에서는 경사각도로 인해 폐주물사의 이송과 반송이 거듭되면서 샤워장치(11)에서 분사되는 물에 의하여 완전한 세척이 이루어지므로 1 단계 2 단계 이송을 통해 폐주물사의 표면에 묻은 접착제와 이물질은 완전히 제거되고 폐수는 일정한 곳으로 모이게 되며 완벽하게 세척된 주물사가 상부로 이송되어 건조실(12)에 들어가서 인공적인 건조장치에 따라 뽀송뽀송한 모래로 만들어 지기 때문에 폐주물사를 최대로 회수하여 재활용 할 수 있는 이점을 얻는 것이다.On the other hand, the treatment apparatus of the present invention collects the waste casting sand in the storage container (1), puts it into the processing container (3) through the conveyor device (2), injects water, and stirs with water in the processing container (3) to absorb sand. While the water-soluble adhesive on the surface is melted and separated, another support arm (5a) installed to the side of the support arm is equipped with a grinding roller (7) is rotated along the bundle of waste molding sand on the process It also has the effect of pulverizing, so that there is an advantage that the dissolving treatment of the adhesive is made at the same time as the pulverization of the waste molding sand, and the fine discharge hole 3a drilled at the bottom of the processing container 3 is fine so that the agglomerated waste molding sand cannot be dropped, but the fine processed material and the falling. Since the bottom has an opening / closing plate 3b, it manages the processing time in the processing container so that the opening and closing plate 3b can be opened and closed properly. Even though the opening and closing plate 3b is always open and high, the fine discharge port 9b is finely divided in the processing tank so that some of the adhesive dissolved therein flows to the outside of the processing tank. 9) can be dropped and the processing material dropped in the transfer gutter is subjected to the process of moving back to the inclined gutter by the transfer screw (10) in this process, due to the inclination angle the transfer and conveyance of the waste casting sand repeated shower device ( 11) Complete cleaning is performed by the water sprayed in 11), so that adhesive and foreign substances on the surface of the waste foundry sand are completely removed through the 1st stage and 2nd stage transfer, the waste water is collected at a certain place, and the perfectly cleaned foundry sand is transferred to the upper part of the drying room. In (12), it is made of soft sand by artificial drying equipment, so the maximum amount of waste foundry sand is maximized. The advantage is that it can be recovered and recycled.
