Description

Technical Field

[0001] The invention relates to the technical field of filtration and recovery of mold release agents, in particular to automatic filtration and recovery equipment for die-casting mold release agents. Background Art

[0002] In the die-casting process, mold release agents play a key role in ensuring mold release efficiency, improving casting surface quality, and extending mold life. There is a significant problem in the current high-pressure and high-flow mold release agent spraying process: since the actual utilization rate of the mold release agent is only 30%-65%, the remaining part is discharged into the sewage pool in the form of wastewater. These wastewaters contain chemical raw materials and organic emulsifiers, which not only lead to high cost losses, but also mix with impurities such as solutions, aluminum chips and engine oil, making subsequent filtration and recycling treatment particularly critical.

[0003] Among them, oil-water separation is a particularly important step in the filtration and recovery of release agents. In the current traditional recovery equipment, the iron belt separation method is usually used. The running iron belt is immersed in the oil-water mixture, and then the attached oil is taken out by the moving iron belt to achieve the effect of oil-water separation. However, during the operation, it is usually necessary to wait for the oil phase to slowly gather and float to a specific adsorption area, which makes the whole process rely on the passive adsorption of natural floating oil. Especially when the oil phase is dispersed, the separation efficiency will be further reduced. At the same time, there are defects such as long separation cycle, low oil phase recovery rate, and large equipment footprint, which makes it difficult to meet the needs of industrial continuous production. Therefore, it is necessary to develop an automatic filtration and recovery equipment for die-casting release agents that can gather oil-water mixtures, enhance separation efficiency, and optimize space utilization, so as to solve the bottleneck of existing technologies and achieve efficient filtration and recovery of release agents.

The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Embodiment 1: A die casting release agent automatic filtering and recycling device, such as Figure 1-Figure 7 As shown, including: Base 1, on which is arranged an oil storage frame 12, and a processing frame 11 located on the right side of the oil storage frame 12, in which an oil-water separation tank 111, a static tank 112 and two ozone tanks 113 are arranged in the processing frame 11 in a clockwise direction, the oil-water separation tank 111 is used as an oil-water separation processing area in wastewater recovery, the static tank 112 is used as a temporary storage area for wastewater after preliminary separation, and can also be used as a processing place for secondary oil-water separation, and the ozone tank 113 is used as an ozone sterilization processing area for wastewater, so as to form a complete In the filtering and recycling process, the oil-water separation tank 111 is close to the oil storage frame 12. An extraction pump 2 is installed between the oil-water separation tank 111 and the static tank 112, between the static tank 112 and the adjacent ozone tank 113, and between the two ozone tanks 113, for extracting and treating wastewater from each treatment tank. It can be seen that the internal structure of the above-mentioned treatment frame 11 is compact, and the integrated layout has a complete process of filtering and recycling treatment. Each link is connected step by step and operates in an orderly manner, which effectively optimizes the use of space and makes the process operation more coherent and efficient. The partition plate 3 is arranged in the oil-water separation tank 111. The highest point of the partition plate 3 is lower than the top surface of the oil-water separation tank 111. The partition plate 3 can separate the oil-water separation tank 111 into two spaces, front and back, so as to achieve the subsequent partitioning and storage of oil and water. The partition plate 3 is a plate-like structure with an open front end and a closed rear end. The left and right sides of the front end are provided with plate surfaces inclined backwards, so as to form a closed flow channel that gradually narrows from front to back. This flow channel can guide the oil-water mixture to initially enter the oil-water separation tank 111, and use the advantages of the structure to gather the floating oil backwards, so that the distribution of the oil is more concentrated, so as to facilitate the subsequent oil-water separation treatment; The oil-water separation mechanism 4 includes a group of mounting frames 41 spaced apart from each other at the top of the processing frame 11, a group of mounting frames 41 having two in number, an oil drain hopper 42 being arranged between the two mounting frames 41, the oil drain hopper 42 being inclined toward the oil storage frame 12, and being able to facilitate the flow and discharge of the oil on the oil drain hopper 42, a group of scraping blocks 48 being arranged on the oil drain hopper 42, and a limit frame 49 being arranged at the front side, a group of scraping blocks 48 having two in number, an assembly frame 43 being fixedly arranged on the right side of the top of the oil drain hopper 42, a separation component for oil-water separation treatment being arranged between the assembly frame 43 and the partition plate 3, the separation component including an oil belt 47, the oil belt 47 being in a conveying state from front to back, so that it is aligned with the flow direction of the wastewater The lower belt body of the oil-attached belt 47 is placed in the oil-water separation tank 111 and extends into the interior of the partition plate 3, and the side of the oil-attached belt 47 fits with the inner wall of the partition plate 3, which can block the flow of the upper oil, so that the lower wastewater can pass normally and be transferred to the rear side of the oil-attached belt 47; the upper belt body of the oil-attached belt 47 passes through the limit frame 49 and the scraper block 48 from front to back in sequence. When the oil adheres to the oil-attached belt 47, the oil-attached belt 47 will first pass through the limit frame 49 and then enter the scraper block 48 as it runs. The two scraper blocks 48 are tightly attached to the oil-attached belt 47, which can effectively scrape off the attached oil. The scraped oil then flows into the oil drain hopper 42 and is drained into the oil storage frame 12, thereby achieving oil-water separation; Two guide rods 51 are fixedly arranged between the left and right sides of the front part of the partition plate 3 and the inner wall of the oil-water separation tank 111. A toggle plate 52 is slidably arranged between the two guide rods 51. The toggle plate 52 slides in the front-to-back direction. A pushing component is arranged between the toggle plate 52 and the separation component to enable the toggle plate 52 to move back and forth. Through the movement of the toggle plate 52, the oil-water mixture can be pushed to gather, and the oil is guided to approach the oil-attached belt 47, so that the oil actively adheres to the oil-attached belt 47, thereby effectively improving the processing efficiency of oil-water separation.

[0030] like Figure 4 and Figure 5 As shown, the separation component also includes a motor 44 installed on an assembly frame 43, a main roller 45 whose end is connected to the output end of the motor 44 is rotatably arranged in the assembly frame 43, a group of slave rollers 46 spaced apart from each other are rotatably arranged between the left and right inner walls of the partition plate 3, and an oil belt 47 is wound between the two slave rollers 46 and the main roller 45.

[0031] like Figure 6 and Figure 7As shown, the pushing assembly includes a coupling plate 5 fixedly arranged at the left and right ends of the slave roller 46 in the front position, a connecting frame 53 sliding through the left and right sides of the partition plate 3 is arranged on the rear side of the toggle plate 52, and a hollow plate 54 is arranged on the left and right ends of the connecting frame 53. The shaft body of the coupling plate 5 slides and rotates and is embedded in the middle groove of the hollow plate 54 on the same side. The crank-connecting rod principle is adopted to coordinate the operation of the slave roller 46, and the toggle plate 52 is driven to move through the cooperation between the coupling plate 5 and the hollow plate 54.

[0032] Specifically, to ensure the concentration of floating oil, the partition plate 3 is first used to limit the space of the oil-water mixture to guide the oil to gather in the direction of the oil-attached belt 47, and at the same time, the tight fit between the oil-attached belt 47 and the partition plate 3 is used to divide the internal space of the partition plate 3 into two layers, further realizing the separation of oil and water. On this basis, the driving effect of the toggle plate 52 is used to make the oil-water mixture continue to move backward, pushing the floating oil gradually close to the oil-attached belt 47, thereby transforming the traditional passive adsorption mode into an efficient active treatment mode. The coordinated cooperation of various parts and regions makes the entire process more coherent and smooth, significantly improving the treatment efficiency, and at the same time ensuring the thoroughness of oil recovery and filtration in wastewater, and ensuring the quality of the recovered release agent.

[0033] like Fig.10 and Fig.11 As shown, a bubbler 8 is provided inside the oil-water separation tank 111. The bubbler 8 generates bubbles, and the bubbles collide and adhere to the oil droplets during the rising process to form a complex of bubbles and oil droplets. With the help of the buoyancy of the bubbles, the complex quickly floats to the liquid surface, promoting the aggregation of the oil phase. In addition, the disturbance caused by the bubbles makes the oil droplets easier to collide and combine, forming larger oil droplets, thereby improving the separation efficiency.

[0034] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 8 and Fig. 9 As shown, it also includes a contact frame 6 arranged on the top of the toggle plate 52, and a mounting frame 61 is arranged on the front side of the top of the processing frame 11, and the mounting frame 61 is located directly above the contact frame 6, and a group of front-to-back spaced limiting grooves 611 are arranged on the left and right sides of the mounting frame 61, and a filter plate 63 located in the mounting frame 61 is slidably embedded between the limiting grooves 611 on both sides, and the filter plate 63 is an angular plate body with a raised middle part, and its rear side part is inclined backward and has a plate body with arranged filter holes, which can be used to filter the oil residue in the wastewater, and the front side part of the filter plate 63 is an inclined and complete plate body, which is used to guide the discharge of the oil residue after filtering and screening, and a toothed plate 62 is fixedly arranged on the left and right sides of the filter plate 63, respectively, and the bottom of the toothed plate 62 has a concave and convex serrated structure, and the toothed plate 62 is contact-pushed with the contact frame 6, and the serrated structure of the toothed plate 62 is utilized to drive the filter plate 63 to move up and down along the limiting groove 611, thereby achieving the effect of shaking the screen.

[0035] like Figure 8 and Fig. 9 As shown, it also includes electric slide rails 64 arranged on the left and right sides of the top of the installation frame 61, a moving frame 65 is arranged between the sliders of the two electric slide rails 64, a scraper 66 is slidably arranged in the moving frame 65, the scraper 66 slides up and down, and an elastic member 67 is arranged between the scraper 66 and the inner wall of the moving frame 65. In this embodiment, the elastic member 67 is a spring. Under the elastic force of the elastic member 67, the bottom of the scraper 66 always keeps in contact with the filter plate 63, so as to scrape off the oil residue retained on the filter plate 63.

[0036] like Figure 1 and Fig.10 As shown, an ozone section 7 is provided on the right side of the base 1. The ozone section 7 includes an ozone machine 71 provided in the middle position of the right side of the base 1, and ozone boxes 72 located on the front and rear sides of the ozone machine 71, which are used to further ozone sterilize the treated wastewater in the ozone tank 113. The treated wastewater is finally transported to the molding proportioning machine for recovery and circulation treatment, and is used to prepare the required release agent.

[0037] When using the device, firstly, discharge the industrial wastewater containing the release agent into the device, and the wastewater flows into the oil-water separation tank 111 in the processing frame 11 through the filter plate 63. At the same time, start the motor 44 to drive the main roller 45 to rotate, thereby driving the oil belt 47 to operate. The rotation of the oil belt 47 will synchronously drive the rotation of the slave roller 46, and drive the hollow plate 54 to move through the connected coupling plate 5. Under the action of the rotation of the coupling plate 5, its shaft slides along the middle groove of the hollow plate 54, and pulls the hollow plate 54 to translate within the rotation range, so as to continue to operate, thereby further driving the connecting frame 53 and the toggle plate 52 to reciprocate back and forth; As the toggle plate 52 moves, the contact frame 6 connected thereto comes into contact with the toothed plate 62, and the concave-convex serrated structure at the bottom of the toothed plate 62 is used to push the top filter plate 63 to shake up and down in the mounting frame 61, thereby separating the oil residue in the wastewater by shaking and screening, and achieving preliminary filtration of the wastewater. When the oil residue accumulates to a certain extent, the electric slide rail 64 is started to drive the moving frame 65 and the scraper 66 to move along the surface of the filter plate 63. Under the action of the elastic member 67, the scraper 66 always keeps in contact with the filter plate 63, thereby scraping out the screened oil residue and ensuring that the filter plate 63 is unobstructed; Next, the wastewater after the filter screen flows into the front space of the oil-water separation tank 111. During this process, the floating oil in the oil-water mixture floats up due to its low density, while the water sinks. The wastewater is continuously pushed to flow by the toggle plate 52, so that the floating oil scattered on the upper layer gradually gathers to the rear area of ​​the partition plate 3 along the channel formed by the partition plate 3. At the same time, the oil belt 47 is in operation, and then the floating oil is adsorbed by the running oil belt 47 and transported upward. When the oil belt 47 with attached oil passes through the limit frame 49, it enters between the scraping blocks 48. The oil falls off under the friction of the scraping blocks 48 and flows into the oil storage frame 12 through the oil drain hopper 42 to complete the oil-water separation. In addition, the bubbler 8 is started synchronously, and the bubbles generated by the bubbler 8 will rise and collide with the oil droplets and adhere to them. With the help of the buoyancy of the bubbles, the oil is accelerated to gather in the oil belt 47 area, which promotes the further gathering of the oil.

[0038] Afterwards, the treated wastewater will overflow over the partition plate 3 under the push of the toggle plate 52, flow into the separation space on the rear side of the oil-water separation tank 111, and be pumped into the static tank 112 by the extraction pump 2. According to the needs of use, if further separation treatment is required, the same separation components as the oil-water separation tank 111 can be assembled on the static tank 112 for secondary separation. Subsequently, the treated wastewater will flow into the two ozone tanks 113 in turn under the pumping of each extraction pump 2, and then flow into the ozone box 72 through the circulation pipe 73, and be sterilized by ozone by the ozone machine 71. Finally, the treated wastewater is sent to the proportioning molding machine to complete the proportioning treatment of the release agent, thereby realizing the entire automated release agent filtration and recovery process.

[0039] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
