Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterjet cutting, and in particular to a waterjet cutting circulating water treatment device. Background Technology
[0002] Waterjet cutting, also known as water jet cutting, is a technology that uses high-pressure water jets for cutting. The water jet starts from a pressurized pump, passes through a high-pressure pipe, and mixes abrasives such as garnet and corundum into the high-pressure water to assist in cutting. It is then ejected from the cutting nozzle. This force and motion are mainly generated by water. Under computer control, it can carve workpieces at will and is less affected by the material texture. Because of its low cost, ease of operation, and high yield, waterjet cutting is gradually becoming the mainstream cutting method in industrial cutting technology.
[0003] Since waterjet cutting uses water as the primary material, the water jets sprayed from the cutting nozzle will mix with abrasive materials such as garnet and diamond after the cutting process is completed. At the same time, they will also mix with cutting chips to form wastewater. Direct discharge of this cutting wastewater has a significant impact on the environment, and it usually needs to be treated before being discharged to minimize the impact on the environment.
[0004] Currently, the common practice in the market for treating wastewater from waterjet cutting is to use sedimentation tanks. The wastewater generated from waterjet cutting is collected in a sedimentation tank, where heavier waste chips and abrasive materials are allowed to settle before being discharged. However, this method is not ideal for treating wastewater. Some lighter waste chips float on the surface of the wastewater, and oil seeping from the cutting machine can also easily mix into the wastewater and float on the surface. Sedimentation cannot treat these floating objects, and direct discharge will also harm the environment.
[0005] In addition, since waterjet cutting requires a large amount of water, if the wastewater from the cutting process cannot be reused, the processing cost will increase significantly. Summary of the Invention

[0029] Example
[0030] Please refer to the instruction manual attached. Figure 1 As shown, the instruction manual is attached. Figure 1The diagram shown is a schematic representation of the system structure of a water-cutting circulating water treatment device according to this utility model. This device is mainly used for filtering and purifying the wastewater generated during water-cutting processes, facilitating reuse, saving water costs, and thus reducing production costs. It also does not harm the natural environment. The device includes a source water tank 1 for storing source water and a purified water tank 7 for storing purified water. The source water is the wastewater generated during water-cutting. The source water tank 1 has a connection point near the top on its outer side that communicates with its interior and exterior. A raw water inlet 11 is connected to the raw water requiring filtration and purification via a pipeline. A submersible sewage pump (not shown) is installed at the end of the pipeline connecting to the raw water inlet 11. This submersible sewage pump is placed in the wastewater pool for chip wastewater and is used to pump raw water into the raw water tank 1. To facilitate control of the water inlet into the raw water tank 1, an electric ball valve 100, electrically connected to the electrical control cabinet, is installed on the raw water inlet 11. The electric ball valve 100 controls the opening and closing of the pipeline connecting to the raw water inlet 11 and the flow rate. Near the bottom of the raw water tank 1, a connection to the inner... The externally connected source water outlet 13 is used to output source water from the source water tank 1. To prevent insufficient pressure from affecting water delivery, a source water booster pump 2 is connected to the source water outlet 13. The source water outlet 13 and the inlet of the source water booster pump 2 are connected by a pipeline. The source water booster pump 2 is electrically connected to an external electrical control cabinet for easy start and stop control. A second manual ball valve 131 is installed on the pipeline connecting the source water outlet 13 and the inlet of the source water booster pump 2. The second manual ball valve 131 facilitates the control of the opening and closing of the pipeline and the flow of water inside. To prevent the amount of source water in the source water tank 1 from exceeding the set target, a source water drain port 12 with internal and external communication is provided on the outside of the source water tank 1 near the bottom. It should be noted that the height of the source water drain port 12 is lower than the height of the source water outlet 13. A first manual ball valve 121 is provided on the source water drain port 12. The opening and closing of the source water drain port 12 is controlled by the first manual ball valve 121. When the amount of source water input into the source water tank 1 exceeds the target, the first manual ball valve 121 can be opened to discharge the source water in the source water tank 1 so that the water level reaches the predetermined position.The top of the water purification tank 7 is equipped with a purified water inlet 71 that communicates with both the inside and outside of the tank. Filtered purified water can be input into the tank through the inlet 71 and stored therein. Near the bottom of the water purification tank 7, a purified water outlet 72 that also communicates with both the inside and outside of the tank is located on the outside. A water supply booster pump 8 is connected to the water outlet 72 to supply purified water to the water jet nozzle. The water supply booster pump 8 is electrically connected to an external electrical control cabinet, which allows for convenient start-up and shutdown control of the pump. The water supply booster pump 8 can increase the output of purified water. Pressure ensures a smoother flow of purified water from the purified water tank 7. The purified water outlet 72 is connected to the inlet of the water booster pump 8 via a pipeline. A fourth manual ball valve 72 is installed on this pipeline, allowing for easy control of the flow rate and connection between the purified water outlet 72 and the water booster pump 8. A second check valve 81 and a sixth manual ball valve 82 are installed at the outlet of the water booster pump 8. The second check valve 81, adjacent to the outlet of the water booster pump 8, prevents backflow of purified water in the pipeline. The flow rate and opening / closing of the water in the outlet pipeline connected to the water booster pump 8 are easily controlled by the sixth manual ball valve 82. To prevent the purified water in the water tank 7 from exceeding the set target, a purified water drain port 73 with internal and external communication is provided on the outside of the water tank 7 near the bottom. It should be noted that the height of the purified water drain port 73 is lower than the height of the purified water outlet 72. A fifth manual ball valve 731 is provided on the purified water drain port 73, and the opening and closing of the purified water drain port 73 is controlled by the fifth manual ball valve 731. If the amount of purified water input into the water tank 7 exceeds the set target, the drain port 73 will be closed. When the target is reached, opening the fifth manual ball valve 731 can discharge the purified water in the purified water tank 7, bringing its water level to the predetermined position. To filter the source water output from the source water tank 1, a filter assembly is installed between the source water booster pump 2 and the purified water tank 7. To ensure filtration effectiveness, the filter assembly consists of a multi-media filter 4 and an activated carbon filter 5 connected in series. The multi-media filter 4 is connected to the source water booster pump 2 and the activated carbon filter 5, and the activated carbon filter 5 is connected to the purified water inlet 71 on the purified water tank 7. For details, please refer to the attached instruction manual. Figure 2As shown, the multi-media filter 4 includes a first tank 41 with a diameter of 350mm. The first tank 41 is made of FRP material lined with a PE anti-corrosion inner liner. An interface connecting the inside and outside is located at the center of its top, and a first backwash control valve 42 is fixedly connected to this interface. This first backwash control valve 42 is a manual backwash control valve, which can be periodically started for backwashing and sewage discharge. It is threadedly connected to the top interface of the first tank 41. The first backwash control valve 42 has a first inlet 421, a first outlet 422, and a first drain outlet 423, all located within the first tank. On the top outer side of body 41, the first inlet 421 is connected to the outlet of the source water booster pump 2 via a pipeline. To improve the filtration effect and allow the source water to filter out the chips, waste materials, and abrasive additives mixed in the water before entering the multi-media filter 4, a bag filter 3 is installed on the pipeline between the outlet of the source water booster pump 2 and the first inlet 421. The inlet of the bag filter 3 is connected to the outlet pipeline of the source water booster pump 2, and the outlet of the bag filter 3 is connected to the first inlet 421 via a pipeline. Through the bag filter 3, the source water entering it can permeate through the filter bag of the required fineness grade to obtain qualified filtrate, while impurity particles are blocked by the filter bag. To control the water flow and opening / closing of the pipeline between the source water booster pump 2 and the bag filter 3, and to prevent backflow of source water output from the outlet of the source water booster pump 2, a first check valve 21 and a third manual ball valve 22 are installed on the pipeline connecting the outlet of the source water booster pump 2 and the inlet of the bag filter 3. The first check valve 21 is adjacent to the outlet of the source water booster pump 2, and the third manual ball valve 22 is adjacent to the inlet of the bag filter 3. A first filter element 43 is installed at the bottom of the first backwash control valve 42. The first filter element 43 is vertically arranged and threadedly connected to the first backwash control valve 42 for easy disassembly and assembly. The first filter element 43 is located in the first tank. Inside tank 41, to further filter the source water entering the first tank 41, a multi-media filter layer 44 composed of anthracite and quartz sand is filled outside the first filter element 43. Specifically, the multi-media filter layer 44 is filled with three sizes of fine filter media: 2-4mm quartz sand, 1-2mm anthracite, and 0.8-1.2mm anthracite. The multi-media filter media can remove tiny impurities, colloids, and organic matter from the water, reducing the turbidity and pollution index of the effluent, so that the effluent water quality meets the requirements of secondary filtration. The first outlet 422 of the first backwash control valve 42 is connected to the activated carbon filter 5 through a pipeline. See the attached instruction manual. Figure 3As shown, the activated carbon filter 5 includes a second tank 51. The second tank 51 has a diameter of 350mm and is made of FRP material lined with a PE anti-corrosion inner liner. An interface connecting the inside and outside is located at the center of its top. A second backwash control valve 52 is fixedly connected to this interface. This second backwash control valve 52 is a manual backwash control valve, which is threadedly connected to the interface at the top of the second tank 51 for easy assembly and disassembly. This manual backwash control valve can be periodically started for backwashing and sewage discharge. The second backwash control valve 52 is threaded and has a second inlet 521, a second outlet 522, and a second drain 523. The second inlet 521, second outlet 522, and second drain 523 are all located on the top outer side of the second tank 51. The second inlet 521 is connected to the first outlet 422 of the first backwash control valve 42 via a pipe, and the second outlet 422 is connected to the purified water inlet 71 of the purified water tank 7 via a pipe. This is for the purpose of filtering water from activated carbon. The liquid filtered by device 5 is further purified by a water purifier 6, which is installed on the pipeline connecting the second outlet 522 and the purified water inlet 71. A second filter element 53 is installed at the bottom of the second backwash control valve 52. The second filter element 53 is vertically arranged and threadedly connected to the second backwash control valve 52 for easy assembly and disassembly. The second filter element 53 is located inside the second tank 51, and an activated carbon layer 54 composed of activated carbon is filled inside the second tank 51 outside the second filter element 53. The activated carbon is 10-24 mesh coconut shell activated carbon. The part of the second tank 51 below the activated carbon layer 54 is filled with a quartz sand layer 55 composed of quartz sand. The activated carbon layer 54 and the quartz sand layer 55 can remove residual chlorine in the water, reduce the oxidation degree of the water, meet the requirements of three-stage filtration water intake, filter out some organic matter, avoid contamination of subsequent filter media, and remove heavy metals and harmful substances in the water, such as trihalides, reduce the total organic carbon in the water, and significantly improve the odor and color of the produced water.
[0031] To monitor the water levels in source water tank 1 and purified water tank 7, please refer to the instruction manual appendix. Figure 1 As shown, both the source water tank 1 and the purified water tank 7 are equipped with level gauges 9 that are electrically connected to the electrical control cabinet. The level gauges 9 are electronic level gauges. The lowest water level mark of the level gauge 9 on the source water tank 1 is at the same height as the source water outlet 12, and the lowest water level mark of the level gauge 9 on the purified water tank 7 is at the same height as the purified water outlet 73, so as to ensure the lowest discharge position of the source water tank 1 and the purified water tank 7 respectively.
[0032] Its specific working principle is as follows: The submersible sewage pump draws the wastewater from the chip wastewater tank to the source water inlet 11 of the source water tank 1, and the source water enters the source water tank 1. The source water in the source water tank 1 is transported to the bag filter 3 by the source water booster pump 2 for preliminary filtration, removing the chip waste and abrasive materials from the source water to obtain qualified filtrate. The filtrate after filtration by the bag filter 3 enters the first filter element 43 through the first inlet 421, and then enters the first tank 41 through the first filter element 43. The liquid entering the first tank 41 is filtered by the multi-media filter layer 44, which removes small impurities, colloids and organic matter in the water and reduces the turbidity and pollution index of the effluent before entering the second inlet 521 through the first outlet 422. The water flows through the second inlet 521, passes through the second filter element 53, and enters the second tank 51. The water entering the second tank 51 is filtered by the activated carbon layer 54 and the quartz sand layer 55, which can remove residual chlorine and reduce the oxidation degree of the water, meeting the requirements of three-stage filtration. It can filter out some organic matter, as well as heavy metals and harmful substances in the water, and reduce the total organic carbon in the water. The water filtered by the activated carbon filter 5 flows through the second outlet 522 to the water purifier 6 for water purification and filtration, achieving the required clean water. The clean water enters the clean water tank 7 through the clean water inlet 71 for storage. The clean water stored in the clean water tank 7 can be pressurized and delivered to the water cutting nozzle by the water supply booster pump 8, realizing the reuse of cutting wastewater.
[0033] This water cutting circulating water treatment device has a simple structure. It filters and purifies the cutting wastewater generated during water cutting by connecting bag filter 3, multi-media filter 4, activated carbon filter 5 and water purifier 6 in series. After purification, the wastewater becomes clean water that can be used for water cutting again, saving water consumption, reducing production costs, and effectively protecting the environment by reusing wastewater, making production and processing more environmentally friendly.
