Description

Technical Field

[0001] This utility model relates to the field of vertical water tank technology, specifically a vertical water tank with cutting fluid filtration and purification function. Background Technology

[0002] In the domestic machine tool processing industry, the water tanks generally used are relatively flat in shape and have a low water level. When encountering complex working conditions, they often cannot effectively filter fine metal chips. The typical working process of the water tanks used in machine tools is as follows: the cutting fluid discharged from the machine tool is filtered through a roller filter and then enters the primary water tank. Then, a booster pump is used to draw cutting fluid from the primary water tank, which is filtered through a vortex separator before entering the secondary water tank.

[0003] In existing technologies, under certain special working conditions, such as machining cast iron parts, a large amount of fine chips are generated. The filtration effect of this filtration system is not ideal for this working condition. Fine chips easily accumulate in the primary water tank, which over time will cause blockage of the submersible pump and pipeline, affecting the performance of the water pump. It requires regular manual cleaning, increasing the cost of manual maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a vertical water tank with cutting fluid filtration and purification function to solve the technical problems mentioned above, such as the easy accumulation of fine cutting chips in the water tank, leading to pipe blockage and the need for regular manual cleaning, resulting in high maintenance costs.

[0005] The present invention achieves the above objectives through the following technical solution: a vertical water tank with cutting fluid filtration and purification function, comprising: a vertical water tank, wherein a filter assembly is installed inside the vertical water tank, and a chip collection trolley is provided at the slag discharge end of the filter assembly, and a high-pressure water pump is connected to the side of the vertical water tank.

[0006] The vertical water tank includes a tank body, inside which a clean water chamber is provided, and on the side of the clean water chamber is a filter chamber. The filter chamber and the clean water chamber are separated by a partition, and a pyramidal chamber is provided at the bottom of the filter chamber.

[0007] The filtration assembly includes a central pump installed at the bottom of the pyramidal chamber, and the output of the central pump is connected to a vortex separator.

[0008] As a further embodiment of this utility model: the output end of the centralized pump is also connected to a drain spray pipe, the end of the drain spray pipe is fixed with a drain nozzle, and a bottom discharge pipe is provided between the centralized pump and the pyramidal chamber.

[0009] As a further embodiment of this utility model: the drain nozzle faces the side wall of the pyramidal chamber, and a separator connecting pipe connects the centralized pump and the vortex separator.

[0010] As a further improvement of this utility model: the liquid outlet end of the vortex separator is connected to a clean water discharge pipe, and the end of the clean water discharge pipe is connected to the clean water tank.

[0011] As a further improvement of this utility model: the slag discharge end at the bottom of the vortex separator faces the chip collection trolley, and an electrical control box is provided on the side of the vortex separator, and the electrical control box is located below the clean water tank.

[0012] As a further improvement of this utility model, multiple heat dissipation holes are provided on the front and rear sides of the box body, and the heat dissipation holes are used for air to enter and exit to achieve heat dissipation.

[0013] As a further improvement of this utility model: a drain pipe is provided between the high-pressure water pump and the filter chamber, and the output end of the high-pressure water pump is connected to the machine bed connecting pipe.

[0024] 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.

[0025] Example 1:

[0026] Example 1

[0027] like Figures 1 to 5 As shown, a vertical water tank with cutting fluid filtration and purification function includes a vertical water tank 1, a filter assembly 3 installed inside the vertical water tank 1, and a chip collection trolley 2 is provided at the slag discharge end of the filter assembly 3, and a high-pressure water pump 4 is connected to the side of the vertical water tank 1.

[0028] The vertical water tank 1 includes a tank body 101, a clean water chamber 103 is provided inside the tank body 101, and a filter chamber 104 is provided on the side of the clean water chamber 103. The filter chamber 104 and the clean water chamber 103 are separated by a partition, and a pyramidal chamber 105 is provided at the bottom of the filter chamber 104.

[0029] The filter assembly 3 includes a central pump 301 installed at the bottom of the pyramidal chamber 105, and the output end of the central pump 301 is connected to a vortex separator 305.

[0030] Specifically, the output end of the centralized pump 301 is also connected to a drain nozzle 304, and a drain nozzle 307 is fixed at the end of the drain nozzle 304. A bottom discharge pipe 303 is provided between the centralized pump 301 and the pyramidal chamber 105.

[0031] Furthermore, the centralized pump 301 is a horizontal pump, which is placed at the bottom of the pyramidal chamber 105. The centralized pump 301 is a high-flow-rate booster pump.

[0032] Specifically, the drain nozzle 307 faces the side wall of the pyramidal chamber 105, and a separator connecting pipe 302 connects the central pump 301 and the vortex separator 305.

[0033] Furthermore, the centralized pump 301 sprays a portion of the pumped liquid through the discharge nozzle 304 and the discharge spray nozzle 307 onto the side wall of the pyramidal chamber 105, and the vortex separator 305 has a conical structure.

[0034] Specifically, the liquid outlet end of the vortex separator 305 is connected to a clean water discharge pipe 306, and the end of the clean water discharge pipe 306 is connected to the clean water tank 103.

[0035] Furthermore, the centralized pump 301 powerfully extracts the cutting fluid collected at the bottom of the cone and pumps it into the vortex separator 305 for fine filtration through the separator connecting pipe 302. The cutting fluid rotates at high speed in the vortex separator 305, and under the action of centrifugal force, the clean cutting fluid is discharged from the clean water discharge pipe 306 at the top and enters the clean water tank 103.

[0036] Specifically, the bottom of the vortex separator 305 has its slag discharge end facing the chip collection trolley 2, and an electrical control box 10 is provided on the side of the vortex separator 305, which is located below the clean water tank 103.

[0037] Furthermore, the cutting fluid rotates at high speed in the vortex separator 305. Under the action of centrifugal force, the clean cutting fluid is discharged from the clean water discharge pipe 306 at the top and enters the clean water tank 103, while the separated metal chips and other residues are directly discharged from the bottom into the chip collection cart 2, realizing automatic slag discharge without manual intervention.

[0038] During use, after the cutting fluid returns from the machine tool, it first enters the filter chamber 104 of the vertical water tank 1. Due to the vertical layout of the water tank, the filter chamber 104 has a large liquid level, providing sufficient depth and time for the natural settling of the chips. The centralized pump 301 located at the bottom of the pyramidal chamber 105 not only powerfully draws the cutting fluid collected at the bottom of the cone through the bottom discharge pipe 303, but also pumps it into the vortex separator 305 for fine filtration through the separator connecting pipe 302. At the same time, a portion of the pumped liquid is sprayed onto the side wall of the pyramidal chamber 105 through the discharge spray pipe 304 and the discharge nozzle 307. The cutting fluid rotates at high speed in the vortex separator 305. Under the action of centrifugal force, the clean cutting fluid is discharged from the clean water discharge pipe 306 at the top and enters the clean water chamber 103. The separated metal chips and other residues are directly discharged from the bottom into the chip collection cart 2. The chip collection cart 2 is installed above the chip conveyor, realizing automatic chip removal without manual intervention.

[0039] In summary, through the filter assembly 3, the centralized pump 301 flushes the tank wall through the drain nozzle 307 to prevent chips from adhering. It can also form a vortex in the tank to strongly agitate the fluid at the bottom, causing fine chips to suspend and be pumped away by the centralized pump 301 along with the main flow, effectively preventing the deposition of cutting chips.

[0040] Example 2

[0041] In addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0042] Specifically, multiple heat dissipation holes 102 are provided on the front and rear sides of the housing 101. The heat dissipation holes 102 are used for air to enter and exit to achieve heat dissipation.

[0043] Furthermore, the location of the heat dissipation hole 102 is adapted to the location of the electrical control box 10, the centralized pump 301, and the vortex separator 305.

[0044] Specifically, a drain pipe 5 is installed between the high-pressure water pump 4 and the filter chamber 104, and the output end of the high-pressure water pump 4 is connected to the machine tool connecting pipe 6.

[0045] Furthermore, the high-pressure water pump 4 is used to extract cutting fluid with a very low impurity concentration from the upper layer of the filter chamber 104.

[0046] Specifically, a float-type oil skimmer 7 is placed inside the filter chamber 104, and a water inlet pipe 9 is connected to the inner wall of the filter chamber 104, with two water outlets 8 at the end of the water inlet pipe 9.

[0047] Furthermore, the floating oil on the surface of the filter chamber 104 is removed by the float-type oil skimmer 7. After the machine tool cutting fluid flows out, it enters the interior of the filter chamber 104 through the water inlet pipe 9. The filter chamber 104 has a large liquid level, which provides sufficient depth and time for the natural settling of the chips. The two water outlets 8 extend deep into the interior of the filter chamber 104.

[0048] During use, the clean water tank 103 is usually full. When clean cutting fluid continuously flows in from the clean water discharge pipe 306, the liquid on the upper layer of the clean water tank 103 will overflow back into the filter tank 104, thus forming a continuous circulating filtration system inside the housing 101, which continuously reduces the concentration of impurities in the filter tank 104. The high-pressure water pump 4, which supplies fluid to the machine tool spindle, draws cutting fluid from the clean water tank 103 with the highest cleanliness and delivers it to the machine tool through the machine tool connecting pipe 6. At the same time, the floating oil on the surface of the liquid in the filter tank 104 is automatically removed by the float-type oil skimmer 7.

[0049] In summary, the vertical water tank 1 has a large liquid level, providing sufficient depth and time for the natural settling of chips. The bottom pyramidal compartment 105 works in conjunction with the centralized pump 301 to make full use of vertical space and reduce the floor area. The centralized pump 301, vortex separator 305 and electrical control box 10 are integrated into the bottom of the water tank, making the overall structure compact and space utilization efficient.

[0050] Working principle: After the cutting fluid returns from the machine tool, it first enters the filter chamber 104 of the vertical water tank 1. Due to the vertical layout of the water tank, the filter chamber 104 has a large liquid level, providing sufficient depth and time for the natural settling of the chips. The centralized pump 301 located at the bottom of the pyramidal chamber 105 not only powerfully draws the cutting fluid collected at the bottom of the cone through the bottom discharge pipe 303, but also pumps it into the vortex separator 305 for fine filtration through the separator connection pipe 302; at the same time, a portion of the pumped fluid is sprayed onto the side wall of the pyramidal chamber 105 through the discharge nozzle 304 and discharge spray pipe 307. The cutting fluid rotates at high speed in the vortex separator 305, and then... Under the action of centrifugal force, clean cutting fluid is discharged from the clean water discharge pipe 306 at the top and enters the clean water tank 103; while the separated metal chips and other residues are directly discharged from the bottom into the chip collection cart 2, realizing automatic slag removal without manual intervention. When clean cutting fluid continuously flows in from the clean water discharge pipe 306, the liquid in the upper layer of the clean water tank 103 will overflow back to the filter tank 104, thus forming a continuous circulating filtration system inside the housing 101, continuously reducing the impurity concentration in the filter tank 104. The high-pressure water pump 4, which supplies fluid to the machine tool spindle, draws cutting fluid from the clean water tank 103 with the highest cleanliness and delivers it to the machine tool through the machine tool connecting pipe 6.
