Detailed Implementation

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0044] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified.

[0045] Filter presses, as a traditional solid-liquid separation device, have relatively mature technology and are widely used in industries such as chemical, metallurgy, environmental protection, and food. Basic structure and working principle: A filter press consists of alternating filter plates and frames, with filter cloth covering the surface of the filter plates as the filter medium. A sealed filter chamber is formed between the filter plates and frames. Pressure is provided by a hydraulic system to press the filter plates together, ensuring the airtightness of the filter chamber. The suspension is forced into the filter chamber by a feed pump; the liquid (filtrate) passes through the filter cloth and is discharged, while solid particles are trapped on the surface of the filter cloth to form a filter cake. After filtration, the hydraulic system releases the filter plates, the filter cake falls off, and the filter cloth can be cleaned or replaced.

[0046] During operation, the wire cutting machine generates a significant amount of waste liquid. This waste liquid is pumped into a filter press for filtration, producing filtered clear liquid, silica sludge, and waste liquid. However, after the filter press has been running for a certain period, the filtration effect diminishes with the increasing number of filtration cycles, the filter cloth lifespan shortens linearly, the liquid output is unsatisfactory, and the waste liquid recycling rate is low.

[0047] In view of the above, embodiments of this application provide a waste liquid treatment device to overcome at least one of the above-mentioned technical problems.

[0048] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment of the application, the waste liquid treatment device includes a filter element 10, a filter press element 20, and a first storage element 30.

[0049] The filter element 10 has a first inlet 11, a first outlet 12, and a second outlet 13. The first inlet 11 is used to introduce waste liquid. The filter press 20 has a second inlet 23 and a third outlet 24, with the second inlet 23 connected to the first outlet 12. The first storage element 30 has a third inlet 36 and a fourth inlet 37, with the third inlet 36 connected to the second outlet 13 and the fourth inlet 37 connected to the third outlet 24.

[0050] Understandably, the waste liquid generated during the operation of the wire cutter can be directly transported to the filter element 10 for treatment through the first inlet 11. The filter element 10 can be a tubular membrane filter, which is typically composed of multiple hollow fiber membrane elements connected in parallel or series. These membrane elements have semi-permeable membrane characteristics. During operation, the waste liquid enters the tubular membrane filter. Under a certain pressure, the waste liquid flows in from one end of the membrane tube. Small molecules permeate through the membrane wall to form clear liquid and are discharged, while large molecules or particles are trapped in the inner cavity of the membrane tube to form turbid liquid. Finally, the clear liquid and turbid liquid are collected and treated separately. This structural design improves filtration efficiency and allows for flexible adjustment of the processing capacity and separation performance according to needs. The clear liquid produced after treatment by the filter element 10 can be discharged through the second outlet 13 and then enters the first storage unit 30 for storage through the third inlet 36 (the second outlet 13 and the third inlet 36 are connected by a pipeline). The turbid liquid produced after processing by the filter element 10 can be discharged through the first outlet 12, and then enters the filter press 20 for further processing through the second inlet 23 (the first outlet 12 and the second inlet 23 can be connected by a pipe). The filter press 20 can filter the turbid liquid entering it. Part of the liquid in the turbid liquid passes through the filter medium inside the filter press 20 to form a recyclable clear liquid. This clear liquid is discharged through the third outlet 24 on the filter press 20, and then enters the interior of the first storage unit 30 through the fourth inlet 37 (the third outlet 24 and the fourth inlet 37 are connected by a pipe). Solid particles in the turbid liquid remain on the surface of the filter medium to form filter residue.

[0051] This structure uses filter element 10 to perform preliminary filtration of the waste liquid generated by the wire cutting machine. Due to the small separation pore size of the fiber membrane element within filter element 10, it can almost trap all bacteria, viruses, colloidal particles, proteins, and large organic molecules in the waste liquid. Therefore, filter element 10 has a high filtration efficiency, and the resulting clear liquid can be directly recycled, thereby improving the waste liquid recycling efficiency. Simultaneously, the filtration process of filter element 10 is carried out dynamically; only a portion of the waste liquid is separated, with some of the liquid in the fiber membrane element becoming clear liquid, while the remainder becomes concentrate flowing out of filter element 10. The filtration rate of filter element 10 can reach an equilibrium value under stable conditions without continuous decay, and the entire process can be sustained for a long time. To further improve the waste liquid recycling efficiency, the concentrate discharged from filter element 10 can be transported to filter press element 20 for further treatment. Through filter press element 20, a portion of the clear liquid can also be obtained. Therefore, by using filter element 10 and filter press element 20, the efficiency of waste liquid recycling can be greatly improved, resource waste can be reduced, and costs can be lowered.

[0052] Please see Figure 2In conjunction with the above embodiments, in some embodiments, the filter press 20 includes a pre-coating part 21 and a filter press 22.

[0053] The pre-coating section 21 has a second inlet 23 and a first interface 25. The filter press section 22 has a second interface 26 and a third outlet 24, with the second interface 26 connected to the first interface 25.

[0054] It is understood that the filter press 20 consists of a pre-coating section 21 and a filter press 22. The second inlet 23 is located on the pre-coating section 21, and the concentrated liquid discharged from the filter 10 enters the pre-coating section 21 through the second inlet 23. The pre-coating section 21 can be a pre-coating tank, which can improve the filtration effect of the coolant. Special pre-coating materials, such as diatomaceous earth and perlite, are usually added to the pre-coating tank. These materials can form a uniform pre-coating layer on the surface of the filter medium (such as filter element, filter screen, etc.). Before entering the formal filtration equipment, the concentrated liquid passes through the pre-coating tank. The pre-coating material adheres to the filter medium in the pre-coating tank, which can improve the filtration accuracy and efficiency of the filter medium, help intercept finer impurity particles, prevent impurities from clogging the filter medium, extend the service life of the filter medium, and facilitate subsequent filtration by the filter press 22. This improves the working efficiency of the filter press 22, increases the service life of the filter cloth inside the filter press 22, ensures the filtration effect of the filter press 22, and thus improves the service life of the filter press 22.

[0055] Alternatively, the pre-coating section 21 can be positioned before the filter element 10. The generated waste liquid is first transported to the pre-coating section 21 for pretreatment, and then the pretreated waste liquid is transported to the filter element 10 for filtration. This improves the filtration effect of the filter element 10 and extends its filtration cycle and service life. Alternatively, the pre-coating section 21 can be positioned both before the filter element 10 and before the pressure filter section 22. This allows the waste liquid to be pretreated by the pre-coating section 21 before entering the corresponding filtration structure. This enables the filtration structure to better filter the waste liquid, improving the filtration effect and reducing the probability of damage to the filtration structure, thus extending its service life.

[0056] The concentrated liquid processed by the pre-coating section 21 is discharged through the first port 25, and then enters the filter press section 22 through the second port 26 (the second port 26 and the first port 25 are connected by a pipe). The filter press section 22 can be a filter press, which can further filter the concentrated liquid to filter out a recyclable clear liquid, thereby increasing the amount of recovered clear liquid. The third outlet 24 is provided on the filter press section 22, and the clear liquid obtained by the filter press section 22 can be discharged through the third outlet 24 into the first storage container 30.

[0057] Please see Figure 2In conjunction with the above embodiments, in some embodiments, the first storage unit 30 includes a transfer unit 31 and a collection unit 32.

[0058] The transfer unit 31 has a third liquid inlet 36, a fourth liquid inlet 37, and a first transfer port 311. The collection unit 32 has a third interface 321, which is connected to the first transfer port 311.

[0059] Understandably, both the third inlet 36 and the fourth inlet 37 are located on the transfer section 31. The clarified liquid produced by the filter element 10 enters the transfer section 31 through the third inlet 36, and the clarified liquid produced by the pressure filter 22 enters the transfer section 31 through the fourth inlet 37. The transfer section 31 can be a transfer tank, which is a container used for the temporary storage and transfer of liquids, playing an important role in the waste liquid treatment process. It is usually made of durable and corrosion-resistant materials, such as stainless steel or plastic, and the appropriate material is selected according to the specific properties of the waste liquid to ensure safety and durability. In the waste liquid treatment process, the transfer tank is mainly used to collect, store, and transport waste liquid, playing a buffering and transfer role, and is one of the key pieces of equipment in the entire treatment system. By using a transfer tank, the flow and storage of waste liquid can be effectively managed. The collected liquid can undergo catalytic reactions within the tank to purify it. Liquid meeting the requirements can be discharged through the first transfer port 311 and then enter the collection unit 32 for storage through the third port 321. Liquid that does not meet the requirements can be transported to other equipment for processing. The collection unit 32 can be a finished product tank and also a storage structure, capable of sealing and preserving the qualified liquid to prevent the entry of external substances and protect it from contamination or loss.

[0060] Please see Figure 3 In conjunction with the above embodiments, in some embodiments, the transfer unit 31 has a second transfer port 312, and the collection unit 32 has a fourth interface 322. The first storage unit 30 also includes an ion exchange unit 33, which has a first exchange port 331 and a second exchange port 332. The first exchange port 331 is connected to the second transfer port 312, and the second exchange port 332 is connected to the fourth interface 322.

[0061] Understandably, a second transfer port 312 is also provided on the transfer section 31. Liquid that does not meet the requirements in the transfer section 31 is discharged through the second transfer port 312 and then enters the ion exchange section 33 through the first exchange port 331 (the first exchange port 331 is connected to the second transfer port 312 via a pipe). The ion exchange section 33 is usually equipped with cation or anion exchange resin to remove metal ions or other target ions from the clarified liquid, so that the clarified liquid in this part meets the requirements. The clarified liquid that meets the requirements after treatment in the ion exchange section 33 is discharged through the second exchange port 332 and then enters the interior of the collection section 32 for storage through the fourth interface 322 (the second exchange port 332 and the fourth interface 322 are connected via a pipe).

[0062] Please see Figure 4 In conjunction with the above embodiments, in some embodiments, the transfer unit 31 has a third transfer port 313, and the first storage unit 30 further includes a sewage discharge unit 34, which has a sewage inlet 341 and is connected to the third transfer port 313.

[0063] Understandably, the transfer section 31 is also equipped with a third transfer port 313. After processing in the transfer section 31, some liquid cannot be purified. This portion of liquid cannot be recycled and needs to be discharged through the third transfer port 313, and then enters the sewage discharge section 34 through the sewage inlet 341 (the sewage inlet 341 and the third transfer port 313 are connected by a pipe). The sewage discharge section 34 can collect this non-recyclable liquid for unified treatment. The sewage discharge section 34 can detect, classify, store, and treat this portion of liquid to ensure it meets environmental protection requirements, reduce the spread of pollution, and ensure the environmental friendliness of industrial production.

[0064] Please see Figure 5 In conjunction with the above embodiments, in some embodiments, the collecting part 32 has a first connection port 323. The first storage unit 30 also includes a dispensing part 35, which has a dispensing port 351 that is connected to the first connection port 323.

[0065] Understandably, a mixing unit 35 is also provided on the first storage unit 30. The mixing unit 35 is provided with a mixing port 351. The liquid that meets the requirements in the collection unit 32 can be discharged through the first connection port 323 and then enter the mixing unit 35 through the mixing port 351 (the mixing port 351 and the first connection port 323 can be connected by a pipe). The mixing unit 35 can mix this portion of liquid to form a finished liquid (that is, a coolant that can be used directly). The mixing unit 35 can be a mixing tank. The mixing tank plays an important role in mixing, diluting, and neutralizing in the liquid treatment process. It is used to uniformly mix liquids of different types or concentrations in proportion and add necessary chemical reagents (such as neutralizing agents, coagulants, etc.) to promote the effect of subsequent treatment.

[0066] Please see Figure 6 In conjunction with the above embodiments, in some embodiments, the waste liquid treatment device further includes a second storage unit 40, which is used to provide waste liquid to the filter unit 10.

[0067] The second storage unit 40 includes a waste liquid lifting section 41, a centralized liquid supply section 42, and a first receiving section 43. The waste liquid lifting section 41 has a waste liquid outlet 411. The centralized liquid supply section 42 has a liquid supply inlet 421 and a liquid supply outlet 422, with the liquid supply inlet 421 communicating with the waste liquid outlet 411. The first receiving section 43 has a first receiving port 431 and a second receiving port 432, with the first receiving port 431 communicating with the liquid supply outlet 422 and the second receiving port 432 communicating with the first liquid inlet 11.

[0068] Understandably, to ensure the continuity of wastewater treatment and avoid intermittent entry of wastewater into the filter element 10, the wastewater generated by the wire cutter can first enter the second storage unit 40, and then enter the filter element 10 for treatment through the second storage unit 40. The second storage unit 40 includes three parts: a wastewater lifting section 41, a centralized liquid supply section 42, and a first receiving section 43. The wastewater generated by the wire cutter can first enter the wastewater lifting section 41, which can be a wastewater lifting tank used to collect and store the wastewater. It performs preliminary adjustment of parameters such as pH and temperature of the collected wastewater to be treated, making it more suitable for the requirements of subsequent treatment processes. Its main function is to use equipment such as a lift pump to lift the wastewater to be treated to a certain height, overcome pipeline resistance and gravity, and transport the wastewater to be treated to the subsequent treatment unit. Waste liquid in the waste liquid lifting section 41 is discharged through waste liquid outlet 411 and then enters the centralized liquid supply section 42 through liquid supply inlet 421 (liquid supply inlet 421 and waste liquid outlet 411 are connected by a pipeline). The centralized liquid supply section 42 can be a centralized liquid supply tank, which, in addition to storing, settling impurities, and regulating temperature, can also provide unified supply to multiple equipment or process points, facilitating the management and control of waste liquid to be treated and reducing the complexity and uncertainty that may be caused by decentralized supply. Waste liquid in the centralized liquid supply section 42 is discharged through liquid supply outlet 422 and then enters the first receiving section 43 through the first receiving port 431 (the first receiving port 431 and liquid supply outlet 422 are connected by a pipeline). The first receiving section 43 can be a waste liquid tank, which has the function of collecting and temporarily storing waste liquid to be treated. It can store the waste liquid discharged from the centralized liquid supply section 42 so that the waste liquid to be treated can be transported to the subsequent treatment structure for treatment. Waste liquid in the first container 43 can be discharged through the second container port 432, and then enter the filter element 10 through the first liquid inlet 11 for filtration (the first liquid inlet 11 and the second container port 432 are connected by a pipe).

[0069] Please see Figure 7 This application also provides a circulation system, including a circulation component 60 and the waste liquid treatment device described above.

[0070] The circulation assembly 60 includes a second receiving section 61, a filtering section 62, and a cutting chamber 63 connected in sequence. The cutting chamber 63 has a waste liquid outlet 631. The second receiving section 61 has a first inlet 611, a second inlet 612, and a second outlet 613. The first inlet 611 is connected to the waste liquid outlet 631. The first inlet 11 of the waste liquid treatment device is connected to the second outlet 613. The first storage component 30 of the waste liquid treatment device has a first outlet 38, which is connected to the second inlet 612.

[0071] Understandably, a circulation component 60 can be installed on the wire cutting machine. During operation, the wire cutting machine needs to deliver usable coolant to the second containment 61. The second containment 61 can be a storage structure on the wire cutting machine. The coolant enters the filter section 62 through the second containment 61. The filter section 62 can be a fine filter tank. If impurities are present in the coolant, the fine filter tank can remove them before the coolant enters the cutting chamber 63 of the wire cutting machine for use. Waste liquid generated after use in the cutting chamber 63 can be discharged through the waste liquid port 631 and then enters the interior of the second containment 61 through the first inlet port 611 (the first inlet port 611 and the waste liquid port 631 are connected by a pipe).

[0072] The waste liquid entering the second containment section 61 can enter the filter section 62 for filtration. The liquid after being processed by the filter section 62 can re-enter the cutting chamber 63 for use, thus forming a cycle, which facilitates the collection and reuse of waste liquid.

[0073] The waste liquid entering the second containment 61 can also enter a waste liquid treatment device for processing, such as entering the filter element 10 of the waste liquid treatment device. The waste liquid is discharged through the second outlet 613 and then enters the filter element 10 for processing through the first inlet 11. If a second storage element 40 is provided between the circulation assembly 60 and the filter element 10 (e.g., Figure 8 As shown, the waste liquid in the second receiving section 61 can be discharged through the second outlet 613 and enter the second storage unit 40 through the waste liquid inlet 412. Specifically, the waste liquid enters the waste liquid lifting section 41 through the waste liquid inlet 412. After being processed in the second storage unit 40, it then enters the filter element 10. A first outlet 38 is provided on the waste liquid treatment device. The first outlet 38 can be provided on the mixing section 35 of the first storage unit 30. The liquid treated by the waste liquid treatment device can be discharged through the first outlet 38, then enter the second receiving section 61 through the second inlet 612, and then enter the cutting chamber 63 for use through the filter element 62.

[0074] When the online cutting machine is in use, the waste liquid can be treated by the circulation component 60, allowing it to be recycled and reducing the amount of coolant that needs to be added to the second container 61 (otherwise, new coolant would need to be continuously added to the second container 61 to supply the cutting chamber 63, consuming a large amount of coolant). When the online cutting machine stops working, the generated waste liquid can be treated by the waste liquid treatment device, and the treated liquid can be transported to the second container 61 for standby, which can also reduce the amount of coolant used and lower costs.

[0075] Please see Figure 7In conjunction with the above embodiments, in some embodiments, the circulation component 60 includes a first valve 64, a second valve 65 and a third valve 66, the second receiving part 61 has a third outlet 614, the filtering part 62 has a third inlet 621, the third outlet 614 and the third inlet 621 are connected by the first valve 64, the first liquid inlet 11 and the second outlet 613 are connected by the second valve 65, and the first outlet 38 and the second inlet 612 are connected by the third valve 66.

[0076] Understandably, a first valve 64, a second valve 65, and a third valve 66 can be installed on the circulation assembly 60 to control the flow direction of the liquid. A first valve 64 can be installed between the second receiving section 61 and the filtering section 62, specifically between the third outlet 614 and the third inlet 621, to control the flow of liquid between them. A second valve 65 can be installed between the second receiving section 61 and the filter element 10, specifically between the first inlet 11 and the second outlet 613, to control the flow of liquid between them. (If a second storage element 40 is installed between the circulation assembly 60 and the filter element 10, the second valve 65 can be installed between the second receiving section 61 and the waste liquid lifting section 41, specifically between the second outlet 613 and the waste liquid inlet 412, as shown below.) Figure 8 (As shown).
