Description

Technical Field

[0001] This utility model relates to the field of water-guided laser machine tool technology, specifically a water-guided laser processing machine tool for wastewater recycling. Background Technology

[0002] A water-guided laser cutting machine is an advanced cutting device that integrates laser technology and high-pressure water jet technology. It achieves precise cutting and engraving of various materials by coordinating high-pressure water jets with a laser beam. Laser cutting technology offers advantages such as high precision, high efficiency, and non-contact operation, while water jet cutting technology provides greater cutting force and better cooling.

[0003] When a water-guided laser cutting machine cuts a workpiece, the laser beam is guided by a high-pressure water jet and acts on the material surface, generating a large amount of fine metal debris and splashed water. During operation, an air gun or pneumatic equipment is typically used to quickly blow the debris and water away from the cutting point using directional airflow, deflecting them to one side and keeping the processing area clean. However, the wastewater generated during processing, mixed with the debris, is discharged directly without filtration, resulting in a significant waste of water resources and potential environmental pollution due to impurities such as metal particles in the wastewater. Furthermore, traditional wastewater treatment methods often involve a single filtration stage, which is insufficient to efficiently separate debris and impurities of different particle sizes, leading to insufficient purity of the recycled water and failing to meet the requirements for recycling. Therefore, a water-guided laser processing machine tool for wastewater recovery is proposed. Utility Model Content

[0004] Based on this, the present invention aims to at least solve one of the technical problems existing in the prior art. To this end, a water-guided laser processing machine tool for wastewater recycling is proposed.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water-guided laser processing machine tool for wastewater recycling, comprising a housing, a processing table fixed in the center of the housing, a water-guided laser cutting head capable of processing a workpiece fixed on the top of the processing table, a touch screen for controlling the start and stop of the water-guided laser cutting head mounted on the outer wall of the housing, and a wastewater frame mounted below the processing table at the bottom of the housing.

[0006] The surface of the processing table is provided with drainage grooves that slope to both sides. Both ends of the processing table are provided with drain outlets that are connected to the drainage grooves. Below each set of drain outlets, inside the outer shell, a filter assembly is installed. The filter assembly includes three sets of guide plates that are equidistantly distributed along the height direction of the outer shell. The end of each set of guide plates is provided with an upwardly bent upper edge. The side walls of the three sets of guide plates are provided with positioning frames that are fixedly connected to the outer shell. An inner liner frame for collecting debris is fitted inside the positioning frame.

[0007] As a preferred technical solution, the bottom of the positioning frame is provided with multiple sets of drainage holes, and the guide plate and the three sets of guide plates are all connected to the inner wall of the outer shell by bolts.

[0008] As a preferred technical solution, each set of the guide plate and the upper folded edge constitutes a folded edge groove for temporarily storing debris. A scraper capable of cleaning debris in the folded edge groove is slidably provided in the guide plate, and the three sets of scrapers are integrally cast.

[0009] As a preferred technical solution, a keyboard board is rotatably provided on the front surface of the housing, and a keyboard that is wirelessly connected to the touch screen can be mounted on the top of the keyboard board.

[0010] As a preferred technical solution, the front surface of the outer shell is rotatably provided with a door in an inclined position, and the door is provided with glass that allows observation of the workpiece processing status.

[0011] As a preferred technical solution, the outer casing is provided with a detachable access door on one side and the rear surface, and the access door is connected to the outer casing with screws.

[0012] As a preferred technical solution, the wastewater frame is provided with multiple sets of support rods on both sides, and filter cloth is threaded through the multiple sets of support rods. The filter cloth is distributed in a wave shape at the top of the wastewater frame.

[0013] In summary, the present invention has the following main advantages:

[0014] This invention guides wastewater and debris generated during processing to the drain outlets at both ends via a sloping drainage groove on the surface of the processing table. The wastewater then falls into the filter assembly. The filter assembly contains a three-layer guide plate and an upper folded edge forming a folded groove to reduce the impact of the water flow, allowing larger debris to settle and be temporarily stored. An integrally formed scraper can easily clean the debris in the folded groove. The inner lining frame further intercepts suspended debris, and the drainage hole at the bottom of the positioning frame allows the pre-filtered wastewater to flow into the wavy filter cloth at the top of the wastewater frame. The filter cloth adsorbs fine impurities by increasing the contact area, and the finally purified wastewater is collected in the wastewater frame. This achieves graded filtration and recycling of processing wastewater and efficient separation and cleaning of debris, improving water resource utilization and machine tool maintenance convenience.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] A water-guided laser processing machine tool for wastewater recycling, such as Figures 1 to 5 As shown, the device includes a housing 100, a processing table 150 fixed in the center of the housing 100, a water-guided laser cutting head that can process workpieces fixed on the top of the processing table 150, a touch screen 130 for controlling the start and stop of the water-guided laser cutting head mounted on the outer wall of the housing 100, and a wastewater frame 160 mounted at the bottom of the processing table 150 inside the housing 100.

[0024] The surface of the processing table 150 is provided with drainage grooves 151 that are inclined to both sides. Both ends of the processing table 150 are provided with drain outlets 152 that are connected to the drainage grooves 151. Below each set of drain outlets 152, inside the outer shell 100, a filter assembly 180 is installed. The filter assembly 180 includes three sets of guide plates 181 that are equidistantly distributed along the height direction of the outer shell 100. The end of each set of guide plates 181 is provided with an upwardly bent upper edge 182. The side walls of the three sets of guide plates 181 are provided with positioning frames 184 that are fixedly connected to the outer shell 100. An inner liner frame 185 for collecting debris is fitted inside the positioning frame 184.

[0025] The bottom of the positioning frame 184 has multiple sets of drainage holes, and the guide plate 181 and the three sets of guide plates 181 are all connected to the inner wall of the outer shell 100 by bolts.

[0026] Each set of guide plates 181 and upper folded edge 182 forms a folded edge groove for temporarily storing debris. A scraper 183 that can clean the debris in the folded edge groove is slidably provided in the guide plate 181. The three sets of scrapers 183 are integrally cast.

[0027] It is worth noting that the upper folded edge 182 is in a state of low center and high edge, which forms a temporary storage groove with the guide plate 181;

[0028] The front surface of the outer casing 100 is tilted and has a door 110. The door 110 has a glass door inside that allows observation of the workpiece processing status. The door 110 can be rotated upward around the connection point with the outer casing 100 to open, so as to facilitate the loading and unloading of the workpiece.

[0029] Multiple sets of support rods 163 are provided on the inner sides of the wastewater frame 160. Filter cloth 170 is threaded through the multiple sets of support rods 163. The filter cloth 170 is distributed in a wavy shape on the top of the wastewater frame 160.

[0030] Support bars 161 are fixed to the front and rear inner walls of the wastewater frame 160. The top of the support bars 161 is bolted with positioning bars 162 for pressing the front and rear edges of the filter cloth 170, so that the filter cloth 170 is stably wavy, so as to filter smaller particles in the water and complete solid-liquid separation.

[0031] The outer wall of the wastewater frame 160 is connected to a drain pipe extending to the outside of the outer casing 100, and the inside of the wastewater frame 160 is connected to a right-angle elbow in the direction of a flange, so as to facilitate the subsequent disassembly of the drain pipe and removal of the wastewater frame 160 for cleaning of the internal sediment.

[0032] As per the instruction manual Figure 2 and Figure 4 As shown, a plate for connecting the fixture is provided at the center of the top of the processing table 150, so that the workpiece to be processed can be positioned to facilitate the processing operation.

[0033] When the workpiece is cut, the debris generated is carried by the water flow and flows evenly to both sides in the drainage tank 151. Then, the water source mixed with the debris flows smoothly into the filter assembly 180 below through the drain outlet 152. After entering the filter assembly 180, the water and debris flow down along the inclined surface of the guide plate 181 and are naturally guided to the temporary storage tank by gravity.

[0034] In the temporary storage tank, water and debris temporarily accumulate. As water continues to flow in from above, the water level in the temporary storage tank gradually rises. When the water level exceeds the height of the upper fold 182, the debris is effectively blocked and retained in the temporary storage tank, while the clarified water overflows from above and flows to the lower guide plate 181. This process is repeated. Through the multi-stage guide and temporary storage mechanism, most of the debris in the water is gradually removed, improving the filtration efficiency. Finally, the water that has been filtered multiple times carries a small amount of residual debris to the bottom wastewater frame 160 for collection and treatment.

[0035] It is worth mentioning that the angle formed by each set of upper folded edges 182 and guide plates 181 is different. This design, by adjusting the airflow path and particle trajectory, allows particles of different sizes to be effectively separated according to their size during passage, thereby achieving efficient filtration of particles of various sizes and improving overall adaptability and filtration accuracy, as shown in the instruction manual. Figure 5 As shown.

[0036] Water entering the wastewater frame 160 is first filtered through the filter cloth 170, which effectively removes tiny debris and impurities from the water. The filter cloth 170 has a wavy structure, which allows debris particles to gather at the lowest point of the waves, while the water flow can smoothly pass through the wavy, inclined surface of the filter cloth 170. Since the water flow mainly passes through the inclined area of ​​the wavy structure, debris is less likely to completely block the entire filter surface of the filter cloth, thus reducing the risk of clogging. At the same time, the filtered water droplets gradually flow into the wastewater frame 160, achieving efficient collection of wastewater.

[0037] Subsequently, the scraper 183 can be manually pushed to slide along the length of the guide plate 181. The scraper 183 can effectively push and guide the accumulated debris and some water in the temporary storage tank into the positioning frame 184. During the pushing process, the debris and water will smoothly enter the positioning frame 184 as the scraper 183 moves, and further collect in the inner liner frame 185. Finally, the operator only needs to remove the inner liner frame 185 from the positioning frame 184 to quickly and conveniently complete the debris cleaning work.

[0038] Please refer to this carefully. Figure 1 The front surface of the housing 100 is rotatably provided with a keyboard 120, and the top of the keyboard 120 can be fitted with a keyboard that is wirelessly connected to the touch screen 130.

[0039] By inputting processing parameters and setting data into the touch screen 130 via the keyboard 120, precise control of the machine tool can be achieved, ensuring the efficiency and accuracy of the workpiece processing.

[0040] The outer casing 100 is provided with a removable access door 140 on one side and the rear surface. The access door 140 is connected to the outer casing 100 with screws.

[0041] This allows for the removal of the internal wastewater frame 160 and the cleaning of debris from the baffle plate 181.

[0042] The parts of the device not covered herein are the same as or can be implemented using existing technologies.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
