Description

Technical Field

[0001] The invention relates to the field of cutting fluid treatment, in particular to a circular cutting fluid treatment machine. Background Art

[0002] The reason why the water-soluble cutting fluid used in the machining field stinks is that the slideway oil used to lubricate the hard rails overflows into the cutting fluid water tank, causing floating oil due to the different specific gravity of oil and water. The floating oil covers the cutting fluid, causing the surface of the cutting fluid to lack oxygen, resulting in the growth of anaerobic bacteria, deterioration and corruption, and producing odor. The floating oil on the surface of the water-soluble cutting fluid will also affect the heat dissipation of the cutting fluid, change the processing conditions, and thus affect the accuracy of the processed workpiece.

[0003] The invention patent with announcement number CN104436847A discloses a cutting fluid regeneration device, including an air pump, a waste liquid tank, a self-priming pump, a primary filter water tank, a float recovery device, an oil-water separator, a bag filter, a waste oil recovery barrel, a secondary filter water tank, a heater, a nozzle, a clean water tank, a detection device, a stop valve and a working box. The above devices work together to process the cutting fluid so that the cutting fluid can be recycled, but the system integration level is low, resulting in a bulky size, which hinders commercial promotion. Summary of the invention

[0004] The purpose of the present invention is to provide a circular cutting fluid treatment machine, which has the advantages of high integration and small size.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a circular cutting fluid treatment machine, comprising a machine body, an air pump, a filter tank and a filter chamber are arranged in the machine body, an oil suction pipe is connected to the filter tank, the filter tank is connected to the air pump, and the air pump is connected to the filter chamber, the machine body comprises a detachably connected upper shell and a lower shell, the air pump and the filter tank are arranged in the lower shell, and the filter chamber is arranged in the upper shell;

[0006] The filter chamber includes an overflow chamber, a slow flow chamber and a cut-off chamber. The air pump is connected to the top of the overflow chamber. A partition is vertically arranged in the upper housing. A first through hole and a second through hole are arranged on the partition. The first through hole connects the overflow chamber and the slow flow chamber, and the second through hole connects the slow flow chamber and the cut-off chamber.

[0007] The intercepting cavity includes a left cavity and a right cavity which are separated. The top of the left cavity is flush with and communicated with the top of the slow-flow cavity. The top of the right cavity is higher than the top of the left cavity. A first drainage pipe is protruding from the top of the left cavity, and a second drainage pipe is arranged in the right cavity.

[0008] By adopting the above technical scheme, the air pump providing power and the filter tank for preliminary filtering of the waste cutting fluid are placed in the lower casing of the machine body, and a filter chamber is arranged in the upper casing. The filter chamber is composed of an overflow chamber, a slow flow chamber and a cut-off chamber. The overflow chamber is used to receive and store the pumped waste cutting fluid. The waste cutting fluid is pumped into the top of the overflow chamber at a faster speed, and after passing through the overflow chamber, it flows smoothly into the slow flow chamber from the first through hole of the partition.

[0009] The waste cutting fluid uses the difference in specific gravity between oil and water to complete the stratification of waste oil and water-soluble cutting fluid in the slow flow chamber. The waste oil floating on the upper layer flows to the top of the left cavity of the intercepting cavity and is discharged from the first drain pipe. The water-soluble cutting fluid in the lower layer flows into the intercepting cavity from the second through hole of the partition and is discharged from the second drain pipe.

[0010] Preferably, the overflow chamber and the intercepting chamber are located on one side of the partition, and the slow flow chamber is located on the other side of the partition.

[0011] By adopting the above technical solution, the partition is used together with the inner wall of the upper shell to form a slow flow chamber, and the remaining part of the upper shell is divided into an overflow chamber and a cut-off chamber. The space in the upper shell can be fully utilized, thereby improving the integration level of each chamber and reducing the overall volume.

[0012] Preferably, a transverse plate is provided in the slow flow chamber, which separates the slow flow chamber into an upper chamber and a lower chamber, the bottom of the upper chamber is connected with the top of the lower chamber, and the upper chamber is connected with the intercepting chamber through a second through hole.

[0013] By adopting the above technical solution, the water-soluble cutting fluid overflows from the top of the lower cavity into the upper cavity, which can further slow down the flow and reduce the flow rate of the liquid poured into the slow flow cavity from the bottom of the overflow cavity.

[0014] Preferably, a baffle is provided in the upper cavity, which divides the upper cavity into a front cavity and a rear cavity. An opening is provided on the transverse plate, which is located at the bottom of the rear cavity. The front cavity is communicated with the intercepting cavity.

[0015] By adopting the above technical solution, the upper cavity is divided into two halves by a baffle, which prolongs the flow path of the liquid in the slow flow cavity and provides sufficient time for the complete separation of oil and water.

[0016] Preferably, sewage outlets are provided at the bottom of the lower cavity and the bottom of the intercepting cavity.

[0017] By adopting the above technical solution, the solid impurities deposited at the bottom of the lower cavity and the bottom of the intercepting cavity can be cleaned out by using the sewage outlet, thereby improving the purity of the water-soluble cutting fluid.

[0018] Preferably, a vertical plate is provided in the right cavity, which separates the right cavity into a right front cavity and a right rear cavity which are connected at the bottom, the right front cavity is located between the slow flow cavity and the right rear cavity, and the second drainage pipe is arranged in the right rear cavity.

[0019] By adopting the above technical solution, the water-soluble cutting fluid in the slow-flow chamber flows into the right front chamber from the second through hole of the partition plate, and flows into the right rear chamber after the liquid level in the right front chamber rises to the top, and then the clean water-soluble cutting fluid is discharged from the second liquid discharge pipe in the right rear chamber. In the process of the water-soluble cutting fluid overflowing from bottom to top in the right front chamber, the solid impurities therein can be further precipitated.

[0020] Preferably, a sealing plate is provided in the right rear cavity, and the second liquid discharge pipe is provided above the sealing plate.

[0021] By adopting the above technical solution, the sealing plate can isolate the water-soluble cutting fluid above the sealing plate from the water-soluble cutting fluid below the sealing plate, thereby preventing the water-soluble cutting fluid above the sealing plate from disturbing the water-soluble cutting fluid below the sealing plate when flowing down from a high place, thereby affecting the sedimentation effect.

[0022] Preferably, the top of the vertical plate is higher than the top of the first liquid discharge pipe and lower than the top of the right cavity.

[0023] By adopting the above technical solution, when the liquid level in the slow flow chamber rises to overflow the top of the first drain pipe, the waste oil is discharged from the first drain pipe. After the waste oil is drained, the first drain pipe is closed. At this time, the air pump continues to pump waste cutting fluid into the filter chamber, so the liquid level in the slow flow chamber continues to rise. Since the slow flow chamber is connected to the intercepting chamber, the liquid levels are the same. When the liquid level in the right front chamber of the intercepting chamber rises to the top, the water-soluble cutting fluid begins to overflow into the right rear chamber and is discharged from the second drain pipe.

[0024] Preferably, the body is in a cylindrical shape.

[0025] By adopting the above technical solution, under the condition of the same occupied area, the cylindrical body has a larger volume, which can improve the oil-water separation efficiency.

[0026] In summary, the present invention has the following beneficial effects:

[0027] 1. The overall structure is compact and small in size, which is convenient for transportation and installation;

[0028] 2. The top opening of the filter chamber is small, which is convenient for sealing and has good anti-odor and anti-fouling effects;

[0029] 3. Only the air pump needs to be powered to complete the recycling of waste cutting fluid, which reduces the processing cost and reduces the discharge of solid and liquid waste, which complies with the government's policy of energy conservation and emission reduction.

DETAILED DESCRIPTION

[0035] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0036] Embodiment: A cutting fluid treatment circular machine, such as Figure 1 As shown, the machine body 1 is cylindrical, and the machine body 1 is formed by detachably connecting an upper housing 1a and a lower housing 1b, and the upper housing 1a is directly sleeved on the top of the lower housing 1b. An air pump 2 and a filter tank 3 are installed in the lower housing 1b, and an oil suction pipe 7 is connected to the filter tank 3. The end of the oil suction pipe 7 has a floating oil suction nozzle 71. The filter tank 3 is connected to the air pump 2 through a pipeline, and the air pump 2 is connected to the filter chamber in the upper housing 1a through a pipeline. The floating oil suction nozzle 71 is placed in a waste cutting fluid tank, and then the waste cutting fluid can be pumped into the filter chamber by turning on the water pump.

[0037] The filter chamber in the upper housing 1a consists of an overflow chamber 4, a slow-flow chamber 5 and an intercepting chamber 6. The air pump 2 is connected to the top of the overflow chamber 4 through a pipeline, the bottom of the overflow chamber 4 is connected to the slow-flow chamber 5, and the slow-flow chamber 5 is connected to the intercepting chamber 6. A partition 8 is vertically arranged in the upper housing 1a, and the partition 8 divides the filter chamber into two semicircular cavities. The cavity on one side of the partition 8 is the slow-flow chamber 5, and the cavity on the other side of the partition 8 is divided into the overflow chamber 4 and the intercepting chamber 6.

[0038] like Figure 2 As shown, a first through hole 81 communicating with the slow flow chamber 5 is provided at the bottom of the overflow chamber 4, that is, a first through hole 81 is provided on the partition 8. When the overflow chamber 4 is filled with waste cutting fluid, the waste cutting fluid continuously pumped in from the top of the overflow chamber 4 presses the waste cutting fluid at the bottom of the overflow chamber 4 into the slow flow chamber 5 through the first through hole 81.

[0039] like Figure 2 , Figure 3As shown, a horizontal plate 12 is fixed horizontally near the bottom of the slow flow chamber 5, and the horizontal plate 12 divides the slow flow chamber 5 into an upper chamber 51 and a lower chamber 52. The upper chamber 51 is further divided into a front chamber 511 and a rear chamber 512 by a baffle 15. The front chamber 511 is connected to the intercepting chamber 6 through the second through hole 82, and the second through hole 82 is located at the bottom of the front chamber 511. An opening is provided on the horizontal plate 12 at the bottom of the rear chamber 512, and the opening makes the rear chamber 512 communicate with the lower chamber 52. A sewage outlet 11 for discharging impurities is provided at the bottom of the lower chamber 52. The waste cutting fluid pressed into the slow flow chamber 5 from the bottom of the overflow chamber 4 first enters the lower chamber 52, then enters the rear chamber 512, and gradually overflows from the rear chamber 512 to the front chamber 511, and finally enters the intercepting chamber 6 from the front chamber 511. When the liquid level in the upper cavity 51 is stable, the liquid level is higher than the height of the baffle 15, and the waste cutting fluid produces oil-water stratification, that is, it is divided into an upper waste oil layer and a lower water-soluble cutting fluid layer. The height of the upper waste oil layer is also higher than the height of the baffle 15. Therefore, when the liquid level is stable, the lower water-soluble cutting fluid overflows from the rear cavity 512 to the front cavity 511, and the waste oil layer still floats on the liquid surface of the upper cavity 51.

[0040] The intercepting chamber 6 is divided into a left chamber 61 and a right chamber 62 which are connected at the bottom by vertical plates. Since the intercepting chamber 6 is connected to the slow-flow chamber 5, according to the communicating vessel principle, the left chamber 61 and the right chamber 62 have the same liquid level as the slow-flow chamber 5. A sewage outlet 11 for discharging impurities is also provided at the bottom of the intercepting chamber 6.

[0041] like Figure 3 As shown, the top of the left cavity 61 is closed, and a first drain pipe 9 in the shape of a curved pipe is inserted, one end of the first drain pipe 9 protrudes from the top of the left cavity 61, and the other end passes from the left cavity 61 to the outside of the body 1. The top of the left cavity 61 is flush with the top of the slow flow cavity 5, and there is a notch on the partition 8, which makes the top of the left cavity 61 communicate with the top of the slow flow cavity 5. When the liquid level in the overflow cavity 4 rises to the top, it can flow into the top of the left cavity 61, and when the liquid level overflows the top of the first drain pipe 9, it is discharged.

[0042] like Figure 3 , Figure 4As shown, the top of the right cavity 62 is higher than the top of the left cavity 61, and the right cavity 62 is divided into a right front cavity 621 and a right rear cavity 622 which are connected at the bottom by a vertical plate 13, and the right front cavity 621 is located between the slow-flow cavity 5 and the right rear cavity 622. The liquid in the slow-flow cavity 5 enters the left cavity 61 and the right cavity 62 through the second through hole 82, and the top of the vertical plate 13 in the right cavity 62 is higher than the top of the first drain pipe 9, but lower than the top of the right cavity 62. When the liquid level overflows the first drain pipe 9, the first drain pipe 9 starts to discharge the waste oil, and the first drain pipe 9 is closed after the waste oil is drained. At this time, the air pump 2 is still pumping in the waste cutting fluid, so the liquid level continues to rise until the water-soluble cutting fluid in the right front cavity 621 rises to the top of the vertical plate 13 and overflows into the right rear cavity 622. A sealing plate 14 is horizontally provided in the right rear chamber 622, which divides the right rear chamber 622 into two parts, and the upper part is provided with a second drainage pipe 10 leading to the outside of the machine body 1. The water-soluble cutting fluid overflowing from the right front chamber 621 falls into the upper part of the right rear chamber 622 and is discharged from the second drainage pipe 10.

[0043] To sum up, the usage and working principle of this type of cutting fluid treatment circular machine are as follows:

[0044] Put the floating oil suction nozzle 71 of the oil suction pipe 7 into the waste cutting fluid tank, turn on the air pump 2, draw the waste cutting fluid into the filter tank 3 to filter out larger solid impurities, and then pump it into the overflow chamber 4, the slow flow chamber 5 and the intercepting chamber 6 in turn. The waste cutting fluid forms oil and water stratification in the slow flow chamber 5: the waste oil in the upper layer can be discharged when it overflows the top of the first drainage pipe 9; the water-soluble cutting fluid in the lower layer enters the intercepting chamber 6 through the second through hole 82 on the partition 8. After the waste oil in the upper layer is completely discharged from the first drainage pipe 9, the first drainage pipe 9 is closed. At this time, the air pump 2 is still pumping the waste cutting fluid continuously, so the liquid levels in the slow flow chamber 5 and the intercepting chamber 6 rise. When the liquid level rises and overflows the vertical plate 13, the cutting fluid overflows from bottom to top to the top of the right front chamber 621 and overflows into the right rear chamber 622, and then is discharged through the second drainage pipe 10. The second drainage pipe 10 is connected to the waste cutting fluid tank with a hose to realize the circulation treatment of the cutting fluid.

[0045] The above-mentioned embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
