[0056] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0057] like Figure 1 and Figure 2 As shown, the first embodiment of the present invention provides a coolant filtering device, which includes a concentration pool 10, a filtering structure 20, a connecting pipe and a support member 30. The concentration pool 10 has a collecting chamber for storing coolant, a liquid inlet and a liquid outlet, and the liquid inlet and the liquid outlet are both connected to the collecting chamber; the liquid inlet is connected to the coolant outlet of the device to be cooled. The filtering structure 20 includes a first filtering component 21 and a second filtering component 22, the second filtering component 22 is sleeved on at least part of the first filtering component 21, the filtering part of the first filtering component 21 is covered on the liquid outlet, and the filtering part of the second filtering component 22 is located on the side of the filtering part of the first filtering component 21 away from the liquid outlet. One end of the connecting pipe is connected to the liquid outlet, and the other end is used to connect to the coolant inlet of the device to be cooled, and the filtering structure 20 is located in the connecting pipe; the support member 30 is fixedly arranged on the inner wall of the connecting pipe and is used to connect or clamp with at least part of the filtering structure 20.

[0058] According to the coolant filter device provided by the first embodiment of the present invention, first, the support member 30 is fixedly arranged at the inner wall of the connecting pipe, and is connected or clamped with at least part of the filter structure 20, thereby ensuring the stability of the filter structure 20 under the condition of high-speed flow of the coolant. This design effectively prevents the filter structure 20 from being displaced or washed away due to the impact of the coolant, thereby ensuring the continuity and reliability of the filtering effect. In addition, through the fixation and support of the support member 30, the filter structure 20 is also less likely to deform under high flow conditions, which helps to maintain its original filtering performance. This not only improves the filtering efficiency, but also extends the service life of the filter structure 20. Secondly, the filter structure 20 includes a first filter component 21 and a second filter component 22, and the second filter component 22 is sleeved on at least part of the first filter component 21. This graded filtering design can not only efficiently remove large particle impurities in the coolant, but also further capture small particle impurities to ensure the cleanliness of the coolant. Therefore, the coolant filter device provided by this embodiment can solve the technical problem that the coolant filter device in the prior art is easily washed away.

[0059] Specifically, the equipment to be cooled includes a machine tool 40 and a chip conveyor 50 .

[0060] Specifically, the support member 30 is an annular structure. In this way, the support member 30 adopts an annular structure and can be evenly distributed on the inner wall of the connecting pipe, providing all-round support for the filter structure 20. This design enables the filter structure 20 to maintain the stability of its shape and position when subjected to the impact of the coolant flow, avoiding deformation or displacement caused by uneven local force. In addition, the use of the annular support member 30 also simplifies the connection between the filter structure 20 and the connecting pipe, improving the assembly efficiency of the device and the overall structural compactness.

[0061] Specifically, the support member 30 is provided with an internal thread structure 31, and the first filter assembly 21 is provided with an external thread structure 24 extending along the length direction of the connecting pipe, the external thread structure 24 is arranged around the periphery of the first filter assembly 21, and the internal thread structure 31 is used for threaded connection with the external thread structure 24. With such an arrangement, the internal thread structure 31 on the support member 30 cooperates with the external thread structure 24 on the first filter assembly 21, thereby achieving a stable connection between the first filter assembly 21 and the support member 30. The threaded connection not only provides mechanical stability, but also allows for convenient disassembly and assembly when necessary without the need for complex tools or additional fixings. This design ensures the stability of the first filter assembly 21 under high-speed flow of coolant, while also facilitating daily maintenance and cleaning, thereby reducing maintenance costs and downtime.

[0062] Specifically, the support member 30 is movably arranged on the connecting pipe. With such a structural arrangement, the movable support member 30 can be flexibly adjusted to adapt to different positions on the filter structure 20 that need to be clamped or connected by the support member 30, effectively improving the use flexibility and installation convenience of the device.

[0063] Specifically, the second filter assembly 22 is provided with an external thread extending along the length direction of the connecting pipe, the external thread is arranged around the periphery of the second filter assembly 22, and the internal thread structure 31 is used for threaded connection with the external thread. With such a structural arrangement, the threaded connection provides a reliable mechanical fixation, ensuring that the second filter assembly 22 can remain stable when the coolant flows at a high speed, preventing displacement or washing away due to fluid impact, thereby ensuring the consistency and reliability of the filtering effect.

[0064] Specifically, the first filter assembly 21 includes a first filter screen 211 and a support member 212. The first filter screen 211 includes an end screen surface 2111 and a side screen surface 2112 that are connected to each other. The side screen surface 2112 is arranged around the periphery of the liquid outlet, and the end screen surface 2111 is located on the side of the side screen surface 2112 away from the liquid outlet. The support member 212 forms a support cavity, and the first filter screen 211 is located in the support cavity and is spaced apart from the support member 212; a flow opening 2121 is arranged on the support member 212, and at least part of the filter portion of the second filter assembly 22 is arranged opposite to the flow opening 2121. With such an arrangement, the first filter screen 211 is composed of the end screen surface 2111 and the side screen surface 2112. This structural design can effectively intercept and filter large particle impurities in the coolant, ensuring the preliminary purification of the coolant before entering the subsequent components. The connection between the end mesh surface 2111 and the side mesh surface 2112 not only increases the filtering area, but also improves the filtering efficiency. In particular, the side mesh surface 2112 is arranged around the liquid outlet to directly protect the coolant outlet and prevent impurities from directly entering the subsequent circulation system. The support cavity surrounded by the bracket 212 provides a stable installation environment for the first filter screen 211, reduces the possibility of the first filter screen 211 being compressed and deformed, and enhances the overall stability of the filter structure 20. The design of the flow opening 2121 ensures that the coolant can flow smoothly to the second filter assembly 22 after preliminary filtration, while reducing the resistance during the flow of the coolant and improving the circulation efficiency.

[0065] Specifically, the bracket member 212 includes a plurality of support links 2122 arranged at intervals along the periphery of the first filter screen 211, and the intervals between two adjacent support links 2122 form a circulation opening 2121. The bracket member 212 also includes an upper support portion 2123 and a lower support portion 2124, and one end of each support link 2122 is connected to the upper support portion 2123, and the other end is connected to the lower support portion 2124. The external thread structure 24 is arranged on the upper support portion 2123. In this way, the plurality of support links 2122 are arranged at intervals along the periphery of the first filter screen 211, which not only provides certain support and protection for the first filter screen 211, and reduces the possibility of its deformation or displacement, but also the circulation openings 2121 between adjacent support links 2122 ensure that the coolant can be evenly distributed, avoid the impact of local high flow rate on the filter screen, and improve the filtering efficiency and stability.

[0066] In this embodiment, the second filter assembly 22 includes a second filter screen 221, which is arranged around the periphery of the bracket 212, and the second filter screen 221 forms the filter part of the second filter assembly 22; the second filter screen 221 is arranged at intervals from the inner wall of the connecting pipe. The flow cross section of the mesh of the second filter screen 221 is smaller than the flow cross section of the mesh of the first filter screen 211. With such a structural arrangement, the second filter screen 221 is arranged around the periphery of the bracket 212, and the flow cross section of its mesh is smaller than that of the first filter screen 211. This design realizes the graded filtration of the coolant. The first filter screen 211 preliminarily removes large particles of impurities, while the second filter screen 221 further captures small particles of impurities, thereby improving the cleanliness of the coolant and the stability of the circulation system. The appropriate spacing between the second filter screen 221 and the inner wall of the connecting pipe prevents the coolant from directly impacting the inner wall of the connecting pipe, reduces the risk of wear and mechanical damage, and at the same time maintains sufficient filtering space to ensure the smooth flow and high-efficiency filtration of the coolant.

[0067] Specifically, at least part of the lower support portion 2124 and the support connecting rod 2122 are used to contact the second filter screen 221 to support the second filter screen 221. In this way, at least part of the lower support portion 2124 and the support connecting rod 2122 are in contact with the second filter screen 221, providing solid support for it, reducing the possibility of displacement or deformation of the second filter screen 221, and ensuring the structural stability and continuity of the filtering effect during the filtering process. In addition, through the contact with the lower support portion 2124 and the support connecting rod 2122, the second filter screen 221 can be accurately positioned, and even under the dynamic changes of the coolant circulation system, its filtering accuracy and structural integrity can be maintained, reducing the decrease in filtering efficiency and coolant pollution caused by the displacement of the filter screen.

[0068] Specifically, the second filter assembly 22 further includes a mounting ring 222. The mounting ring 222 is sleeved on the bracket member 212; the mounting ring 222 is provided with an insertion groove 2221, the insertion groove 2221 extends around the periphery of the bracket member 212, the notch of the insertion groove 2221 is arranged in the direction of the mounting ring 222 away from the first filter screen 211, and the insertion groove 2221 is used to insert the end of the second filter screen 221. With such a structural arrangement, the arrangement of the mounting ring 222 not only provides a stable installation position for the second filter screen 221, but also realizes the rapid installation and replacement of the second filter screen 221 through the insertion groove 2221, thereby improving the maintenance efficiency. The insertion groove 2221 is arranged around the periphery of the bracket member 212, and its notch is arranged in the direction of the mounting ring 222 away from the first filter screen 211. This design ensures that the second filter screen 221 is installed in the correct position, avoids installation errors or unstable connections, and thus improves the overall stability and filtering effect of the filter assembly.

[0069] Specifically, the insertion groove 2221 is configured to match the end of the second filter 221. A first clip is provided in the insertion groove 2221, and a second clip is provided at the end of the second filter 221 to engage with the first clip. In this way, by providing the first clip in the insertion groove 2221 and engaging with the second clip at the end of the second filter 221, this design achieves a firm fixation of the second filter 221, prevents displacement of the filter caused by the flow of coolant, and ensures the continuity and reliability of the filtering process. The snap-fit ​​design makes the installation and disassembly of the second filter 221 very simple, and the operator can replace the filter without using tools during maintenance, which greatly saves maintenance time and cost and improves production efficiency.

[0070] Specifically, the mounting ring 222 is sleeved on a plurality of supporting links 2122 .

[0071] Specifically, the first filter screen 211 and the second filter screen 221 are arranged in a staggered manner. In this way, a more comprehensive filtering effect can be achieved. This staggered arrangement ensures that the coolant can contact more filtering area during the filtering process, improves the filtering efficiency, and reduces the ineffective waste of the filter screen area.

[0072] Specifically, the second filter assembly 22 further includes a fixing plate 223, which is arranged on a side of the second filter screen 221 away from the first filter screen 211 and connected to the second filter screen 221. With such a structural arrangement, the structural stability of the second filter screen 221 is enhanced, deformation or displacement of the second filter screen 221 under high-speed flow of the coolant is avoided, and its long-term reliable operation is ensured. The fixing plate 223 also serves to provide an easy-to-operate plane for operators, facilitate the installation and removal of the second filter screen 221, and simplify the maintenance process.

[0073] Specifically, the second filter screen 221 is an annular structure.

[0074] In this embodiment, the filter structure 20 also includes a seal 23, which is located in the connecting pipe. One side of the seal 23 is arranged in contact with the portion of the concentrated pool 10 used to enclose the liquid outlet, and the other side is arranged in contact with the first filter component 21; a through port 231 is arranged on the seal 23, the liquid outlet and the through port 231 are arranged relative to each other, and the filter part of the first filter component 21 is covered on the through port 231. With such a structural arrangement, the coolant can be prevented from leaking during the filtering process, and the closedness and high efficiency of the system are maintained. The relative arrangement of the through port 231 and the liquid outlet ensures the smooth flow of the coolant. At the same time, the filter part of the first filter component 21 is covered on the through port 231, which further improves the filtering efficiency and filtering accuracy. This design optimizes the flow path of the coolant and also provides a stable working environment for subsequent filter components.

[0075] In this embodiment, the filter structure 20 also includes a pressure difference detection member, the first pressure detection end of the pressure difference detection member is located on the side of the filter structure 20 close to the liquid outlet, and the second pressure detection end of the pressure difference detection member is located on the side of the filter structure 20 away from the liquid outlet; the coolant filter device also includes a first control member and an alarm, the pressure difference detection member and the alarm are both connected to the first control member, and the first control member is used to control the alarm to sound an alarm according to the detection result of the pressure difference detection member. With such a structural setting, the pressure difference detection member can monitor the pressure difference on both sides of the filter structure 20 in real time. This monitoring is very important for judging the cleanliness and filtering efficiency of the filter screen. When the pressure difference exceeds the preset value, it indicates that the filter screen may be blocked and needs to be cleaned or replaced. The first control member and the alarm are used in combination, so that the device can automatically trigger an alarm when the pressure difference is detected to remind the operator to perform maintenance in time, avoid the coolant circulation failure caused by the filter screen blockage, and ensure the continuity and safety of the production process. This automatic control system reduces the need for manual monitoring, improves the intelligence level of the equipment, and enhances its applicability and reliability in industrial environments.

[0076] like Figure 3 As shown, the second embodiment of the present invention provides a production line, and the production line includes the coolant filtering device provided in the first embodiment.

[0077] According to the production line provided by the second embodiment of the present invention, first, the support member 30 is fixedly arranged at the inner wall of the connecting pipe, and is connected or clamped with at least part of the filter structure 20, thereby ensuring the stability of the filter structure 20 under the condition of high-speed flow of the coolant. This design effectively prevents the filter structure 20 from being displaced or washed away due to the impact of the coolant, thereby ensuring the continuity and reliability of the filtering effect. Moreover, through the fixation and support of the support member 30, the filter structure 20 is also less likely to deform under high flow conditions, which helps to maintain its original filtering performance. This not only improves the filtering efficiency, but also extends the service life of the filter structure 20. Secondly, the filter structure 20 includes a first filter component 21 and a second filter component 22, and the second filter component 22 is sleeved on at least part of the first filter component 21. This graded filtering design can not only efficiently remove large particle impurities in the coolant, but also further capture small particle impurities to ensure the cleanliness of the coolant. Therefore, the production line provided by this embodiment can solve the technical problem that the coolant filter device in the prior art is easily washed away.

[0078] Specifically, the production line also includes a machine tool 40 and a chip conveyor 50. The machine tool 40 includes a machine tool body and a first liquid collecting tank for storing the coolant discharged from the machine tool body; the first liquid collecting tank is connected to the liquid inlet of the coolant filter device; the other end of the connecting pipe of the coolant filter device is connected to the coolant inlet of the machine tool body. The chip conveyor 50 includes a chip conveyor body and a second liquid collecting tank for storing the coolant discharged from the chip conveyor body; the second liquid collecting tank is connected to the liquid inlet; the other end of the connecting pipe is connected to the coolant inlet of the chip conveyor body. The adoption of such a structural setting ensures that the coolant discharged from the machine tool 40 and the chip conveyor 50 can smoothly enter the filter device for purification. This integrated design improves the efficiency of resource utilization and reduces the waste of coolant. The closed-loop circulation of the coolant is effectively realized. The purified coolant can enter the machine tool 40 and the chip conveyor 50 again, reducing the addition of new coolant, reducing production costs, and also reducing the impact on the environment.

[0079] Specifically, there are plural machine tools 40 and plural chip conveyors 50 .

[0080] Specifically, in order to achieve efficient distribution and circulation of the coolant, the production line also includes a circulation pump 60, which has a first inlet 61, a second inlet 62, a first outlet 63 and a second outlet 64. The first liquid collecting tank and the second liquid collecting tank are both connected to the first inlet 61; the first outlet 63 is connected to the liquid inlet; the second inlet 62 is connected to the connecting pipe, and the coolant inlet of the machine tool body and the coolant inlet of the chip conveyor body are both connected to the second outlet 64.

[0081] Specifically, the production line also includes a second control component, and the production line also includes a pressure detection component, which is arranged at the second outlet 64 and is used to detect the pressure of the coolant flowing out of the second outlet 64. The circulation pump 60 and the pressure detection component are both connected to the second control component to control the rotation speed of the circulation pump 60 according to the detection result of the pressure detection component. With such a structural arrangement, the pressure detection component can monitor the pressure of the coolant flowing out of the second outlet 64 in real time. This real-time monitoring is essential to ensure the stable supply of coolant in the machine tool 40 and the chip conveyor 50. When abnormal pressure is detected, the second control component can respond quickly and adjust the rotation speed of the circulation pump 60, avoiding insufficient or excessive supply of coolant due to pressure fluctuations, and ensuring the continuity of the production process and the normal operation of the equipment.

[0082] Specifically, the production line also includes at least two flow detection parts, one of the at least two flow detection parts is arranged on the machine tool body and used to detect the coolant flow in the machine tool body, and the other of the at least two flow detection parts is arranged on the chip conveyor body and used to detect the coolant flow in the chip conveyor body; at least two flow detection parts and the circulating pump 60 are connected to the second control part to control the rotation speed of the circulating pump 60 according to the detection results of the at least two flow detection parts. With such a structural setting, more comprehensive coolant usage information can be provided, helping operators understand the consumption of coolant and adjust the production plan in time. The connection with the second control part allows the rotation speed of the circulating pump 60 to be automatically adjusted according to the change of the coolant flow, ensuring the uniform distribution of the coolant among the various devices, avoiding the reduction of cooling effect or equipment damage caused by uneven flow, and improving production efficiency and equipment stability.

[0083] Specifically, when the coolant filtering device is working, the coolant filtered by the filter structure 20 is sequentially fed from the liquid delivery pipe and the liquid spray pipe into the multiple machine tools 40 and the multiple chip conveyors 50 for use through the circulating pump 60; the coolant mixture discharged from the machine tools 40 and the chip conveyors 50 is sequentially returned to the centralized pool 10 through the liquid discharge pipe and the liquid inlet pipe through the circulating pump 60. In this way, the multiple machine tools 40 and the multiple chip conveyors 50 share the coolant in the centralized pool 10, and each time, only a certain amount of water and reagents need to be added to the centralized pool 10 to uniformly adjust the coolant composition and viscosity, and there is no need to separately adjust the coolant for each machine tool 40 and the chip conveyor 50, so that the multiple machine tools 40 and the multiple chip conveyors 50 can be provided with coolant at the same time, saving time and improving the efficiency of adding coolant. The refluxed coolant can be precipitated through the concentration pool 10 to precipitate the debris in the refluxed coolant, and at the same time facilitate the cleaning of the debris. The precipitated coolant enters the filter structure 20 for filtration, and the large particles of impurities are captured and filtered through the fixed coarse filter bucket (equivalent to the first filter component 21), and then the small particles of impurities enter the replaceable cylindrical filter (equivalent to the second filter component 22) downward, and are captured by the replaceable cylindrical filter. The filtered coolant passes through the replaceable cylindrical filter and is then discharged outward through the return pipe. After use, the impurities inside the fixed coarse filter bucket are dumped, and then the replaceable cylindrical filter is pulled down from the outer surface of the filter bracket (equivalent to the bracket 212) to replace the replaceable cylindrical filter, thereby reducing the filtration cost. At the same time, the replaceable cylindrical filter is very convenient to replace, and a good graded filtration effect can also be guaranteed.

[0084] Specifically, the coolant generated by the machine tool 40 during the processing will flow into the sump at the bottom of the machine tool. After the chip conveyor 50 separates the waste chips from the coolant, it will send the coolant into the sump. The coolant in the sump is transported to the central pool 10 through the infusion pipe. In the central pool 10, the coolant passes through a filtering device (such as a magnetic filter, a paper filter, a centrifugal filter, etc.) to remove impurities to ensure the cleanliness of the coolant. The filtered coolant is pressurized by a circulation pump 60 and redistributed to each machine tool 40 and the chip conveyor 50 through the infusion pipe and the spray pipe.

[0085] Specifically, the production line is equipped with a temperature sensor, which is used to monitor the temperature of the coolant to prevent overheating from affecting the processing effect. According to the monitoring data, the system can automatically adjust the speed of the circulation pump 60 and the opening of the valve to ensure the normal circulation of the coolant. When the system detects an abnormal situation (such as insufficient flow, excessive pressure, excessive temperature, etc.), it will issue an alarm signal to remind the operator to deal with it in time.

[0086] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: centralized management and recycling of coolant are realized; continuous and stable coolant supply is provided to multiple machine tools, while reducing coolant consumption and waste generation.
