Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, specifically to a precision grinding machine filter water tank. Background Technology

[0002] A grinding machine is a machine tool that uses grinding wheels to grind the surface of a workpiece. When the grinding wheel grinds the workpiece, it generates heat, which raises the temperature of the grinding wheel and the workpiece. If the heat cannot dissipate quickly, the temperature of the grinding wheel and the workpiece will become too high, which will affect the machining quality of the workpiece. Therefore, cutting fluid is required during the cutting process of a grinding machine. Cutting fluid can quickly remove heat, reduce the temperature of the workpiece, grinding wheel and cutting tool, prevent the workpiece from deforming or burning due to overheating, and also extend the service life of the grinding wheel and cutting tool.

[0003] A search revealed that patent application number CN202421143050.0 discloses a grinding machine filter water tank, which achieves filtration by setting up a buffer chamber and a filter chamber, and fixing a filter plate in the filter chamber. Although the device can intercept impurities in the grinding fluid to a certain extent by setting up the filter plate, the filter plate can only filter larger particles of impurities. It is not effective in filtering fine impurities and non-magnetic particles, and cannot meet the strict requirements of high-precision grinding machines for the cleanliness of grinding fluid. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a precision grinding machine filter water tank, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A precision grinding machine filter water tank includes a water receiving tank, and a primary water tank is installed below one end of the water receiving tank.

[0007] The water receiving trough has an outlet at one end and is inclined toward the outlet. A collection trough is located in front of the outlet. A magnetic separator is installed on the primary water tank. A secondary water tank is placed on one side of the primary water tank. A booster pump is installed on the primary water tank. The primary water tank is connected to the paper bag roller filter through the booster pump. A water tank thermostat is installed on the secondary water tank. A paper bag roller filter is installed at one end of the secondary water tank. An electrical control box is installed on the secondary water tank at the end opposite to the paper bag roller filter from the water tank thermostat.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, a first level gauge is installed on the primary water tank, and a second level gauge is installed on the secondary water tank.

[0010] The beneficial effects of adopting the above-mentioned further solutions are:

[0011] The first level gauge monitors the water level in the primary water tank in real time. When the water level approaches or reaches the warning value, it can promptly send a signal to remind the operator to prevent the grinding fluid in the primary water tank from overflowing, thus avoiding a dirty working environment and potential safety hazards caused by liquid spillage. The second level gauge accurately monitors the water level in the secondary water tank to ensure a continuous and stable supply of cooling water to the equipment. In the event of a water shortage, it can quickly issue an early warning, allowing the operator to handle the situation promptly and prevent the equipment from being damaged by high temperature due to water shortage, thus ensuring the normal and stable operation of the grinding machine.

[0012] Furthermore, the magnetic separator is located between the water outlet and the primary water tank.

[0013] The beneficial effects of adopting the above-mentioned further solutions are:

[0014] This design ensures that the grinding fluid flowing from the water tank passes through a magnetic separator immediately before entering the primary water tank. This promptly adsorbs and separates residual ferromagnetic metal impurities from the grinding fluid, preventing these impurities from settling or adhering to the inner wall of the primary water tank, thus reducing the frequency of tank cleaning. Simultaneously, pre-filtering impurities reduces the load on subsequent processing stages, improves the overall efficiency and stability of the filtration system, and ensures that the grinding fluid in the primary water tank remains in a relatively clean state.

[0015] Furthermore, a first waste hopper is placed on one side of the magnetic separator.

[0016] The beneficial effects of adopting the above-mentioned further solutions are:

[0017] The ferromagnetic metal impurities separated by the magnetic separator can fall directly into the first waste slag hopper, achieving centralized collection of waste slag. This design facilitates regular cleaning of waste slag by operators, eliminating the need for frequent disassembly of the magnetic separator for cleaning, simplifying the maintenance process, and saving maintenance time and labor costs. At the same time, centralized collection of waste slag keeps the work area clean, preventing waste sludge from being scattered and causing environmental pollution or safety hazards, thus improving the safety and standardization of the working environment.

[0018] Furthermore, a second waste hopper is placed on one side of the paper bag roller filter.

[0019] The beneficial effects of adopting the above-mentioned further solutions are:

[0020] When the paper bag roller filter performs deep filtration of grinding fluid, the fine impurities and non-magnetic particles intercepted can fall directly into the second waste hopper. This makes the waste collection process more convenient and efficient, allowing operators to clean the waste in a timely manner and ensuring that the filtration effect of the paper bag roller filter does not decrease due to waste accumulation. At the same time, the independent waste hopper helps to keep the surrounding environment of the equipment clean, facilitates the observation of the filter's operating status, and allows for timely processing when the waste hopper is close to full, ensuring the continuous and stable operation of the filtration system.

[0021] Furthermore, the water receiving trough is Z-shaped, and the collection trough is located at the end of the water receiving trough near the water outlet.

[0022] The beneficial effects of adopting the above-mentioned further solutions are:

[0023] The Z-shaped water receiving tank increases the flow path and residence time of the grinding fluid within the tank, allowing metal foreign objects more time to settle into the collection tank due to gravity, thus improving collection efficiency. Simultaneously, the Z-shaped structure acts as a buffer, slowing the flow rate of the grinding fluid and preventing metal foreign objects from directly bypassing the collection tank due to excessive flow. The collection tank is located near the outlet, maximizing the interception of foreign objects about to flow into the primary water tank, ensuring a significant reduction in the foreign object content of the grinding fluid entering the primary tank. This effectively protects the subsequent magnetic separator and other filtration equipment, extending their service life.

[0024] This utility model provides a precision grinding machine filter water tank. It has the following beneficial effects:

[0025] The primary water tank is lower than the machine tool's return water inlet, and the water inlet is tilted towards the outlet, which facilitates the natural return of the grinding fluid to the primary water tank by gravity, ensuring the smooth recovery of the grinding fluid.

[0026] A collection tank is installed on the water receiving tank. Utilizing the principle of mass density, it can collect metal foreign objects such as bolts and nuts that may be mixed into the grinding fluid during grinding machine debugging or maintenance, preventing them from entering the magnetic separator, avoiding damage to the magnetic separator, and extending its service life.

[0027] The first level gauge is installed in the primary water tank to prevent water level from overflowing; the second level gauge is installed in the secondary water tank to ensure the supply of cooling water to the equipment and to provide timely warnings in case of water shortage, which helps to ensure the normal operation of the grinding machine and avoid equipment failure due to abnormal water level.

[0028] The primary water tank is connected to the paper bag roller filter via a booster pump, and the secondary water tank is also equipped with a paper bag roller filter, which can further filter the grinding fluid, improve the cleanliness of the grinding fluid, and help ensure the machining accuracy of the grinding machine.

[0029] The magnetic separator has a first waste hopper on one side and the paper bag roller filter has a second waste hopper on the other side, which facilitates the collection of separated waste, makes cleaning easier, and keeps the working environment clean.

[0030] A water tank thermostat is installed on the secondary water tank to control the liquid temperature inside the tank, ensuring that the equipment operates under suitable temperature conditions, which helps to improve the stability and processing quality of the grinding machine.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please see Figures 1 to 3 As shown, the embodiments provided by this utility model are as follows: Example 1

[0040] A precision grinding machine filter water tank includes a water receiving tank 4, with a primary water tank 5 installed below one end of the water receiving tank 4. The primary water tank 5 is lower than the machine tool's return water inlet to facilitate the return of the grinding fluid. An outlet 402 is provided at one end of the water receiving tank 4, and the water receiving tank 4 is inclined towards the outlet 402. A collection tank 401 is located in front of the outlet 402 in the water receiving tank 4. During the debugging or maintenance of the grinding machine, foreign objects such as bolts and nuts may fall into the machine tool and potentially be carried to the primary water tank 5 along with the grinding fluid. In this case, the grinding fluid will pass through a magnetic separator 7, potentially damaging the magnetic separator 7. The collecting trough 401 utilizes the principle of mass density. Metal parts such as bolts and nuts that fall into the collecting trough 401 will not continue to flow along the water tank to the magnetic separator 7. The receiving trough 4 is Z-shaped, and the collecting trough 401 is located at the end of the receiving trough 4 close to the outlet 402. The Z-shaped design of the receiving trough 4 can increase the flow path and residence time of the grinding fluid in the tank, allowing metal foreign objects more time to settle into the collecting trough 401 due to gravity, thus improving the collection efficiency of foreign objects. At the same time, the Z-shaped structure plays a buffering role to a certain extent, slowing down the flow rate of the grinding fluid and preventing metal foreign objects from directly crossing the collecting trough 401 due to excessive flow rate. The collection tank 401 is located near the outlet 402, which can intercept foreign objects that are about to flow into the primary water tank 5 to the maximum extent, ensuring that the foreign object content in the grinding fluid entering the primary water tank 5 is greatly reduced, effectively protecting the subsequent magnetic separator 7 and other filtration equipment, and extending their service life. The primary water tank 5 is equipped with a magnetic separator 7, which is located between the outlet 402 and the primary water tank 5, so that the grinding fluid flowing out of the water tank 4 can be processed by the magnetic separator 7 as soon as possible before entering the primary water tank 5. In this way, residual ferromagnetic metal impurities in the grinding fluid can be adsorbed and separated in a timely manner, preventing these impurities from settling or adhering to the inner wall of the primary water tank 5, thus reducing the frequency of water tank cleaning. Simultaneously, pre-filtering impurities reduces the load on subsequent processing stages, improves the overall efficiency and stability of the filtration system, and ensures that the grinding fluid in the primary water tank 5 remains relatively clean. A first waste hopper 8 is placed on one side of the magnetic separator 7, allowing the ferromagnetic metal impurities separated by the magnetic separator 7 to fall directly into the first waste hopper 8, achieving centralized collection of waste. This design facilitates regular waste cleaning by operators, eliminating the need for frequent disassembly of the magnetic separator 7 for cleaning, simplifying the maintenance process, and saving maintenance time and labor costs. Furthermore, centralized waste collection maintains the cleanliness of the work area, preventing waste from being scattered and causing environmental pollution or safety hazards, thus improving the safety and standardization of the working environment. Example 2

[0041] To achieve efficient filtration and recycling of grinding fluid, ensure stable operation of the grinding machine, and improve system maintenance convenience, for example, such as Figures 1 to 3As shown, this utility model also includes: a secondary water tank 10 placed on one side of the primary water tank 5; a first level gauge 6 installed on the primary water tank 5; the function of the first level gauge 6 is to ensure that the water level in the primary water tank 5 does not overflow, and to supply water to the secondary water tank 10 according to the water level; a second level gauge 11 installed on the secondary water tank 10; the function of the second level gauge 11 is to ensure the water level in the secondary water tank 10, ensuring a continuous supply of cooling water for the equipment, and to issue an early warning in case of water shortage; the first level gauge 6 can monitor the water level in the primary water tank 5 in real time, and when the water level approaches or reaches the warning value, it can promptly send a signal to remind the operator to prevent the grinding fluid in the primary water tank 5 from overflowing, avoiding a dirty working environment and potential safety hazards caused by liquid overflow; the second level gauge 6 can monitor the water level in the primary water tank 5 in real time, and when the water level approaches or reaches the warning value, it can promptly send a signal to remind the operator to prevent the grinding fluid in the primary water tank 5 from overflowing, avoiding a dirty working environment and potential safety hazards caused by liquid overflow; the second level gauge 10 can also be used to monitor the water level in the primary water tank 5. The second level gauge 11 accurately monitors the liquid level in the secondary water tank 10, ensuring a continuous and stable supply of cooling water to the equipment. In case of water shortage, it can quickly issue an early warning, facilitating timely handling by operators and preventing damage to the equipment due to high temperature caused by water shortage, thus ensuring the normal and stable operation of the grinding machine. The primary water tank 5 is equipped with a booster pump 12, which is connected to the paper bag roller filter 3 through the booster pump 12. The secondary water tank 10 is equipped with a water tank thermostat 2, and a paper bag roller filter 3 is installed at one end of the secondary water tank 10. A second waste hopper 9 is placed on one side of the paper bag roller filter 3. When the paper bag roller filter 3 performs deep filtration of the grinding fluid, the fine impurities and non-magnetic particles intercepted by the paper bag roller filter 3 can fall directly into the second waste hopper 9. This makes the waste collection process more convenient and efficient, allowing operators to clean up the waste in a timely manner and ensuring that the filtration effect of the paper bag roller filter 3 does not decrease due to the accumulation of waste. At the same time, the independent waste hopper helps to keep the surrounding environment of the equipment clean and facilitates the observation of the filter's operating status. When the waste hopper is close to full, it can be dealt with in a timely manner, ensuring the continuous and stable operation of the filtration system. The electrical control box 1 is installed on the secondary water tank 10 at the end of the water tank thermostat 2 away from the paper bag roller filter 3.

[0042] Working principle:

[0043] Grinding fluid flows into the receiving tank from the machine tool's return inlet, which is located above the primary water tank, under gravity. The receiving tank is inclined, allowing the grinding fluid to flow smoothly towards the outlet. During this process, if bolts, nuts, or other metal foreign objects fall into the grinding fluid during machine setup or maintenance, they will, due to their greater weight and density, fall into the collection tank in front of the outlet, preventing them from entering subsequent processing stages.

[0044] After initial separation of foreign matter, the grinding fluid flows from the outlet of the water inlet into the primary water tank. A magnetic separator installed on the primary water tank processes the incoming grinding fluid, using magnetic principles to adsorb and separate residual ferromagnetic metal impurities. The separated waste falls into the first waste hopper, thus achieving initial purification of the grinding fluid.

[0045] The first level gauge on the primary water tank monitors the water level in real time to ensure it does not overflow. When the set level is reached, the grinding fluid in the primary water tank is pumped to the paper bag roller filter for further filtration via a booster pump. The booster pump provides power for the transmission of the grinding fluid, ensuring fluid flow.

[0046] After entering the paper bag roller filter, the grinding fluid undergoes deep purification by the filter media, which intercepts and filters out fine impurities and non-magnetic particles. Waste generated during the filtration process falls into a second waste hopper on one side of the paper bag roller filter. The cleanliness of the grinding fluid is significantly improved after treatment by the paper bag roller filter.

[0047] The grinding fluid, after deep filtration, flows into the secondary water tank for storage. A second level gauge on the secondary water tank monitors the water level to ensure a continuous supply of cooling water to the equipment and issues an early warning in case of water shortage. Simultaneously, a water tank thermostat adjusts and controls the liquid temperature in the secondary water tank according to set requirements, maintaining the liquid temperature within a suitable range to provide stable operating conditions for the grinding machine.

[0048] As the core of the entire water filtration system, the electrical control box monitors and controls the operation of each component, including starting and stopping the booster pump, receiving and processing the level gauge signal, and setting and adjusting the parameters of the water tank thermostat, ensuring that the entire system operates stably and efficiently according to the predetermined program.
