Description

Technical Field

[0001] The invention relates to the technical field of oil collection for detection, and in particular to an oil collection device for detection in a filter. Background Art

[0002] Grinding oil is suitable for surface grinding, external cylindrical coreless grinding and shallow groove grinding. It can be used to grind surface-hardened workpieces and drill chip grooves on high-productivity machine tools. It can be used for gear grinding. The existing grinding oil will contain a large amount of processing impurities after each use, resulting in larger oil residue impurity particles. Therefore, before using it again, it is necessary to precipitate the impurities in the grinding oil and then carry out the next step of purification. At present, industrial oil filters mainly consist of dirty liquid tanks, clean liquid tanks, heaters, vacuum filters, vacuum pumps, oil drain pumps, drainage pumps and cooling devices.

[0003] The filter pump in the vacuum filter can filter metal debris of different particle sizes and different quantities in the oil at different operating frequencies, and the power consumption of the filter pump at different operating frequencies is also different. A detection instrument that can detect the particle size and quantity of metal debris in the oil is set between the dirty liquid tank and the filter pump in the vacuum filter. The oil before entering the filter pump is detected by the detection instrument. The detected data is transmitted to the filter pump with a frequency converter, so that the operating frequency of the frequency converter can be adjusted, so that the metal debris in the oil can be accurately filtered at the lowest energy consumption, without causing unnecessary consumption of the frequency converter, thereby achieving the purpose of energy saving.

[0004] When sampling the oil in the dirty oil tank, if some existing sampling devices are used, the collected oil samples are easily limited and cannot represent the oil in the entire dirty oil tank, which may eventually lead to inaccurate test results. In addition, when some existing sampling devices are sampling, the oil is easy to adhere to the sampling devices, which is not only troublesome to clean later, but also easy to cause oil leakage, thereby polluting the surrounding environment. For this reason, a collection device for oil detection in a filter is proposed. Summary of the invention

When the collection mechanism and the fixed cleaning mechanism are pulled off the collection tube, the fixed cleaning mechanism can clean the oil remaining on the surface of the collection tube to ensure that there will be no outflow of oil.

DETAILED DESCRIPTION

[0025] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Please refer to Figure 1-Figure 6 The present invention provides a technical solution: a collection device for oil detection in a filter, comprising a collection tube 1, a motor 3 is provided at the top of the collection tube 1, a connecting mechanism 2 is fixedly installed between the collection tube 1 and the motor 3, a collection mechanism 4 is provided on the collection tube 1, a fixed cleaning mechanism 5 is installed on the collection mechanism 4, the collection mechanism 4 comprises a collection bucket 41 and a cylinder 42 which are coaxially arranged and fixedly connected, when the collection tube 1 penetrates into the oil to collect it, the oil enters the collection bucket 41 through the collection tube 1 and the connecting mechanism 2, and the excess oil is discharged through the cylinder 42, when the collection is completed, the fixed cleaning mechanism 5 is pulled downward, and the oil attached to the outside of the collection tube 1 is cleaned by the fixed cleaning mechanism 5.

[0027] Furthermore, the collected oil is collected by setting up a collecting bucket 41 and a cylinder 42 . If the collected oil contains bubbles, the bubbles will float up and be discharged from the cylinder 42 along with the excess oil due to their lighter specific gravity.

[0028] An auger 11 is rotatably installed in the collection tube 1, and the connecting mechanism 2 includes a three-way pipe 21. The ends of the collection tube 1 and the motor 3 that are close to each other are respectively fixedly connected to the two ends of the coaxial three-way pipe 21, and the output shaft of the motor 3 is fixedly connected to the end of the auger 11. A soft curved pipe 22 is fixedly sleeved on the end of the three-way pipe 21 that is away from the auger 11 and the motor 3.

[0029] Furthermore, the rotating auger 11 can cause the oil to drive the metal debris to move upward synchronously, preventing the metal debris from sinking due to its heaviness when the oil rises in the collection tube 1, and ultimately ensuring that the metal content in the oil entering the collection barrel 41 is consistent with the metal content in the collected oil.

[0030] A connecting pipe 45 is fixedly installed through the collecting barrel 41 , and the connecting pipe 45 is detachably connected to the flexible curved pipe 22 . A valve 46 is provided on the connecting pipe 45 .

[0031] An annular box 43 is fixedly installed on the bottom inner wall of the collecting barrel 41, and a plurality of nozzles 44 distributed in a circular array are fixedly installed through the top of the annular box 43. The top ends of the plurality of nozzles 44 are all inclined. A connecting pipe 47 is fixedly installed through the connecting pipe 45, and a valve 2 49 is provided on the connecting pipe 47. The bottom end of the connecting pipe 47 passes through the collecting barrel 41 and the annular box 43 and is fixedly connected to the collecting barrel 41 and the annular box 43.

[0032] Furthermore, since the top ends of the multiple nozzles 44 are all inclined, the oil sprayed from the multiple nozzles 44 can drive the vortex rotation in the collecting barrel 41, and the metal debris is driven by the oil to rotate together, thereby preventing the metal debris in the oil from accumulating on the top of the annular box 43.

[0033] The fixed cleaning mechanism 5 includes an annular block 51 that passes through the top of the collecting barrel 41 and is fixedly connected to the collecting barrel 41. A plurality of arc blocks 52 distributed in a circular array are fixedly installed at the bottom of the annular block 51. Prisms 53 are fixedly installed through the plurality of arc blocks 52. An arc plate 55 is fixedly installed at one end of the plurality of prisms 53 that are close to each other. Conical arc plates 56 are fixedly installed at the bottom ends of the plurality of arc plates 55. The plurality of conical arc plates 56 are in the shape of a cone.

[0034] A rotating ring plate 58 is rotatably installed on the inner side of the annular block 51, and the top of the arc plate 55 is slidably connected to the bottom of the rotating ring plate 58. The rotating ring plate 58 is provided with a plurality of adjustment holes 581 distributed in a circular array. The top ends of the plurality of arc plates 55 are rotatably installed with circular shafts 57, and the plurality of circular shafts 57 are respectively rollingly installed in the corresponding adjustment holes 581.

[0035] A baffle 59 is fixedly mounted on one end of the plurality of prisms 53 that is away from each other. A spring 54 is slidably sleeved on the prism 53 , and both ends of the spring 54 are fixedly connected to the arc block 52 and the arc plate 55 , respectively.

[0036] A plurality of positioning bars 48 distributed in a circumferential array are fixedly mounted on the inner wall of the cylinder 42 .

[0037] Furthermore, when the collection tube 1 passes through the cylinder 42, the multiple positioning bars 48 will abut against the outer wall of the collection tube 1. Through the restriction of the multiple positioning bars 48, it is ensured that the cylinder 42 can remain coaxial with the collection tube 1. When the collection mechanism 4 is sleeved on the collection tube 1, the collection mechanism 4 can move along the axis of the collection tube 1.

[0038] A switch handle 31 is fixedly mounted on the motor 3 , and a gripping plate 32 is fixedly mounted at the connection between the motor 3 and the three-way pipe 21 .

[0039] Furthermore, the switch handle 31 and the gripping plate 32 facilitate the placement and gripping of the entire device, and the switch handle 31 also facilitates the turning on / off of the motor 3 .

[0040] In this embodiment: when collecting oil, first turn the rotating ring plate 58, and the rotating ring plate 58 drives the multiple circular shafts 57 to move away from each other, and the multiple circular shafts 57 then drive the multiple arc plates 55 and the conical arc plates 56 to move away from each other. During the process of the multiple arc plates 55 moving away from each other, the multiple springs 54 will be compressed, and then the collection tube 1 will pass through the fixed cleaning mechanism 5 and the cylinder 42, and then the fixed cleaning mechanism 5 and the collection mechanism 4 will be pushed to move toward the motor 3, and then the connecting tube 45 and the soft curved tube 22 will be clamped together, and then the rotating ring plate 58 will be released. Under the restoring elastic force of the multiple compressed springs 54, the multiple arc plates 55 will drive the multiple conical arc plates 56 to approach each other and clamp the collection tube 1. At the same time, two adjacent conical arc plates 56 will fit together. Through the clamping of the multiple conical arc plates 56 and the clamping of the connecting tube 45 and the soft curved tube 22, the collection mechanism 4 and the fixed cleaning mechanism 5 will be fixed on the collection tube 1;

[0041] Then, the bottom end of the collection tube 1 is inserted into the oil, and the auger 11 is driven to rotate by starting the motor 3. The rotating auger 11 carries the oil into the collection tube 1 and rises in the collection tube 1. After the oil rises, it will enter the soft bend pipe 22. The oil entering the soft bend pipe 22 will enter the connecting pipe 45. At this time, the valve 1 46 is in a closed state and the valve 2 49 is in an open state. The oil entering the connecting pipe 45 will enter the annular box 43 through the connecting pipe 47. The oil entering the annular box 43 is then sprayed out through multiple nozzles 44. When the oil level between the collection barrel 41 and the cylinder 42 increases, the oil sprayed from the multiple nozzles 44 will cause the oil between the collection barrel 41 and the cylinder 42 to rotate. The rotating oil can drive the metal debris to rotate synchronously, thereby preventing the metal debris in the oil from accumulating on the top of the annular box 43.

[0042] When the oil level in the collection barrel 41 continues to rise, as the oil extracted by the collection tube 1 increases, the excess oil in the collection barrel 41 will flow out of the cylinder 42 after flooding the top of the cylinder 42, thereby ensuring that the oil in the collection barrel 41 will not continue to increase;

[0043] After the oil collection is completed, the motor 3 is turned off, and the connecting pipe 45 and the soft bend pipe 22 are separated. Then, the collecting mechanism 4 is pulled downward. When the collecting mechanism 4 drives the fixed cleaning mechanism 5 to move downward, the multiple conical arc plates 56 close to the outer wall of the collecting tube 1 can scrape off the oil attached to the outer wall of the collecting tube 1 during the downward movement. When the collecting mechanism 4 and the fixed cleaning mechanism 5 are separated from the collecting tube 1, the oil on the outer surface of the collecting tube 1 is also cleaned. Then, the valve 2 49 is closed and the valve 1 46 is opened. Then, the collecting barrel 41 is tilted, and the oil in the collecting barrel 41 is poured out from the connecting pipe 45 and collected through a special detection vessel. At the same time, the closed valve 2 49 can prevent the metal debris remaining in the annular box 43 from entering the connecting pipe 45, so as to avoid affecting the subsequent oil detection.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
