Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a cooling and filtering device for machine tools. Background Technology

[0002] With the continuous upgrading of modern enterprises and the vigorous development of industrial technology, the machining field has placed higher demands on the precision of parts. In machining processes such as turning, milling, and drilling, cutting tools are used to cut the outer surface of the workpiece to obtain the required shape and size. During this process, the outer surface of the workpiece is cut, and the temperature of both the workpiece and the cutting tool surfaces continuously rises. This higher temperature directly affects the machining accuracy.

[0003] Therefore, during the aforementioned turning, shaving, and drilling processes, it is often necessary to spray coolant onto the machining area to lower the machining temperature and ensure machining accuracy. The coolant needs to be recycled to reduce production costs.

[0004] However, the recycled coolant often contains a large amount of iron filings. If it is directly recycled, it will not only affect the service life of equipment such as circulating water pumps, but the coolant containing iron filings will also directly affect the machining accuracy when used in conjunction with machining. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a cooling and filtering device for machine tools, which solves the problem of iron filings in the existing recycled coolant.

[0006] The objective of this utility model can be achieved through the following technical solutions: A cooling and filtration device for machine tools includes a water tank. The device further comprises a vortex separator, a top-open sedimentation tank, a clean water tank, and a cooling machine fixed to the water tank for cooling the medium within the tank. The vortex separator has a water inlet, an impurity outlet, and a clean liquid outlet. The clean liquid outlet is connected to the inner cavity of the water tank via a clean liquid pipe. The impurity outlet is located at the bottom of the vortex separator. The sedimentation tank is fixed to the upper inner side of the clean water tank, and a gap exists between the outer wall of one side of the sedimentation tank and the inner wall of the clean water tank. The sedimentation tank is located below the impurity outlet. A return water inlet is provided through one side of the upper part of the clean water tank, and the return water inlet is connected to the inner cavity of the water tank via a return water pipe. A water pump capable of extracting the medium from the inner cavity of the water tank is also fixed to the water tank.

[0007] The machine tool's cooling filtration device is used to cool and filter the cooling water recycled after machining. In practice, it needs to be used in conjunction with a recovery tank and a lift pump. The recovery tank is placed directly below the cooling water usage area to receive the cooling water that falls naturally under its own gravity after use. The lift pump sends the cooling water from the recovery tank to the inlet of the vortex separator. After entering the vortex separator, the cooling water containing impurities such as iron filings is separated and discharged downwards from the impurity outlet. The separated clean water is sent from the clean liquid outlet through the clean liquid pipe to the inner cavity of the water tank for storage. The cooling water containing impurities flows downwards into the sedimentation tank, where it settles and the impurities settle. When the sedimentation tank is full, the cooling water overflows from the open top of the sedimentation tank and flows downwards into the clean water tank through the gap between the sedimentation tank and the clean water tank. The cooling water is also allowed to settle in the purification tank for secondary sedimentation of impurities. As the water level gradually rises to the top of the purification tank, the upper layer of cooling water flows into the inner cavity of the water tank through the return inlet and return pipe for storage. The cooling water stored in the water tank is cooled by a cooling machine to lower its temperature and ensure better cooling effect. When needed, the cooling water in the inner cavity of the water tank is directly drawn out by a water pump. Here, the vortex separator and the cooling machine are existing technologies, and their specific structures and working principles will not be described in detail.

[0008] In the cooling and filtration device for this machine tool, the recycled cooling water is first separated by a vortex separator, and then sent to a water tank for storage after passing through a sedimentation tank and a clean water tank for double sedimentation. The water tank can also be used for further sedimentation of impurities, which can maximize the filtration and recycling of impurities in the cooling water and ensure the low temperature of the cooling water. This allows the recycled cooling water to effectively meet the needs of machining and ensure the machining accuracy of the workpiece.

[0009] In the aforementioned cooling and filtration device for machine tools, the clean water tank is a square tank with one side wall inclined relative to the vertical direction. The width of the clean water tank gradually increases from bottom to top. A horizontally arranged plate-shaped support plate is fixed to the outer side of this side wall, and a slag collection box with an open top is provided on the support plate. The inclined side wall of the clean water tank, making it smaller at the bottom and larger at the top, facilitates the user's ability to easily inspect impurities within the tank from top to bottom. The slag collection box also facilitates the user's cleaning of impurities from the clean water tank.

[0010] In the aforementioned cooling and filtration device for machine tools, a vertically arranged plate-shaped partition is fixed inside the water tank. The partition divides the inner cavity of the water tank into a sedimentation zone and a clean water zone. A water outlet connecting the sedimentation zone and the clean water zone is provided through the upper part of the partition. The clean water pipe is connected to the sedimentation zone, and the return water pipe and the inlet of the water pump are both connected to the clean water zone. The sedimentation zone in the water tank is used to further settle the cooling water, improving the filtration effect. The upper layer of clean cooling water flows to the clean water zone through the water outlet, and the water pump draws water from the clean water zone for use.

[0011] In the aforementioned cooling and filtration device for machine tools, the cooler is fixed to the top of the water tank above the sedimentation zone, and the heat exchange pipes of the cooler extend into the sedimentation zone. The vortex separator is positioned above the clean water zone. The top of the partition, located on one side of the clean water zone, has a liquid guide hopper that is open at the top and closed at the bottom. The clean liquid pipe connects to the liquid guide hopper. The partition has a notch connecting the liquid guide hopper and the sedimentation zone. By installing the cooler and the vortex separator at different positions in the water tank, and correspondingly providing liquid guide hoppers in the clean water zone to direct the cooling water to the sedimentation zone, the distribution of pipes is facilitated, and interference is avoided.

[0012] In the aforementioned cooling and filtration device for machine tools, a sedimentation hopper with an open top and closed bottom is fixed to the inner wall of the water tank at the upper part of the clean water zone. A water inlet is provided through the upper side wall of the sedimentation hopper, and the return water pipe is connected to the sedimentation hopper. Another sedimentation hopper is installed within the clean water zone to collect the cooling water from the return water pipe and to subject the cooling water to further sedimentation and filtration, thereby improving the filtration effect.

[0013] In the aforementioned cooling and filtration device for machine tools, a diversion block is fixed to the upper side of the water tank. The diversion block has an inlet connected to the outlet of the water pump and several outlets. The diversion block can divide the cooling water pumped by the water pump into several branches and send them out separately for use by multiple devices. When not in use, the excess outlets can be sealed with plugs or other structures.

[0014] In the aforementioned cooling and filtration device for machine tools, the water tank includes an independent tank body and a base. The base has a water receiving tray on top, and the bottom surface of the water receiving tray is flat. The bottom surface of the tank body is also flat, and the tank body is placed on top of the water receiving tray. The water receiving tray can collect cooling water that leaks from the water tank, preventing environmental pollution and facilitating the recycling of cooling water.

[0015] Compared with existing technologies, the cooling filtration device for this machine tool first separates the recycled cooling water through a vortex separator, then passes it through a sedimentation tank and a clean water tank for double sedimentation before sending it to a water tank for storage. The water tank can also be used for further sedimentation of impurities, which can maximize the filtration and recycling of impurities in the cooling water and ensure the low temperature of the cooling water. This allows the recycled cooling water to effectively meet the needs of machining and ensure the machining accuracy of the workpiece. Attached Figure Description

[0022] like Figure 2As shown, the filtration structure includes a clean water tank 4 with an open top, fixed to the upper side of the housing 1e; a sedimentation tank 3 with an open top, fixed to the inner side of the upper part of the clean water tank 4; and a vortex separator 2 fixed to the top of the clean water tank 4. The vortex separator 2 has an inlet 2a, an impurity outlet 2b, and a clean liquid outlet 2c. The inlet 2a of the vortex separator 2 is located on the side and is connected to a recovery tank containing recycled cooling water via an inlet pipe. A pressure gauge is connected to the inlet pipe. The clean liquid outlet 2c is located at the top of the vortex separator 2 and is connected to the inner cavity of the water tank 1 via a clean liquid pipe 6. The impurity outlet 2b is located at the bottom of the vortex separator 2. There is a gap between the outer wall of the sedimentation tank 3 and the inner wall of the clean water tank 4. The sedimentation tank 3 is located directly below the impurity outlet 2b. A return water outlet 4a is provided through the upper side of the clean water tank 4, and the return water outlet 4a is connected to the inner cavity of the water tank 1 via a return water pipe 7. In this embodiment, the water purification tank 4 is a square tank. The side wall of the tank with the gap between it and the sedimentation tank 3 is inclined relative to the vertical direction, and the width of the water purification tank 4 gradually increases from bottom to top. A horizontally arranged plate-shaped support plate 9 is fixed to the outer side of this side wall of the water purification tank 4, and a slag receiving box 10 with an open top is provided on the support plate 9. If necessary, a scooping rod for removing impurities can be placed at the top opening of the water purification tank 4 to remove the impurities and pour them into the slag receiving box 10.

[0023] like Figure 3 As shown, a vertically arranged plate-shaped partition 11 is fixed inside the water tank 1. The inner cavity of the water tank 1 is divided into a sedimentation zone 1a and a purified water zone 1b by the partition 11. A water outlet connecting the sedimentation zone 1a and the purified water zone 1b is opened through the upper part of the partition 11. The purified liquid pipe 6 is connected to the sedimentation zone 1a, and the return water pipe 7 and the inlet of the water pump 8 are both connected to the purified water zone 1b. The cooler 5 is fixed on the top of the water tank 1 above the sedimentation zone 1a, and the heat exchange pipe of the cooler 5 extends into the sedimentation zone 1a. The vortex separator 2 is set above the purified water zone 1b. The top of the partition 11, located on one side of the purified water zone 1b, has a liquid guide hopper 1c that is open at the top and closed at the bottom. The purified liquid pipe 6 is connected to the liquid guide hopper 1c. A notch 11a is opened on the partition 11 to connect the liquid guide hopper 1c and the sedimentation zone 1a. The bottom surface of the liquid guide hopper 1c is flat and inclined towards the sedimentation zone 1a.

[0024] The machine tool cooling filter device is used to cool and filter the cooling water recycled after machining. In specific use, it needs to be used in conjunction with a recycling tank and a lift pump. The recycling tank is placed directly below the location where the cooling water is used to receive the cooling water that falls naturally under its own gravity after use. The lift pump is used to send the cooling water in the recycling tank to the inlet 2a of the vortex separator 2.

[0025] After cooling water enters the vortex separator 2 through the inlet 2a, the vortex separator 2 separates the portion of cooling water containing impurities such as iron filings, and discharges it downwards from the impurity outlet 2b. The cooling water containing impurities flows downwards into the sedimentation tank 3, where it settles and the impurities settle. When the sedimentation tank 3 is full, the cooling water overflows from the open top of the sedimentation tank 3 and flows downwards into the clean water tank 4 through the gap between the sedimentation tank 3 and the clean water tank 4. The cooling water also settles in the clean water tank 4 for secondary sedimentation of impurities. When the water level of the cooling water gradually rises to the upper part of the clean water tank 4, the upper layer of cooling water can flow to the sedimentation hopper 1d through the return water inlet 4a and the return water pipe 7. After settling again in the sedimentation hopper 1d, it can overflow from the water outlet into the clean water zone 1b. Meanwhile, the purified water separated by the vortex separator 2 is sent from the purified liquid outlet 2c through the purified liquid pipe 6 to the guide hopper 1c located below the purified water tank 4. After being guided by the guide hopper 1c, it flows into the sedimentation zone 1a, where it settles. When the water level in the sedimentation zone 1a is higher than the inlet, the upper layer of coolant can enter the purified water zone 1b.

[0026] When needed, the water pump 8 directly extracts the cooling water from the inner cavity of the water tank 1 and sends it to the equipment that needs to use cooling water through the diverter block 12.
