DETAILED DESCRIPTION

[0025] The technical solution of the present utility model will be further described below in conjunction with the embodiments and drawings.

[0026] Example 1

[0027] like Figure 1-4 As shown, a pre-filter device for a water tank of a wire cutting machine includes a box body 1 and a filter unit 2. The filter unit 2 is arranged inside the box body 1 and is used to filter the machining fluid in the machine tool water tank (not shown).

[0028] Specifically, the upper end of the box body 1 is open, and a baffle 11 is provided inside it. A connecting pipe 12 is provided on the baffle, thereby dividing the box body 1 into a first pool body and a second pool body that are interconnected; a water outlet pipe 13 is also provided on the box body, and the water outlet pipe 13 is connected to the machine tool water tank; the filter unit is arranged in the first pool body and connected to the machine tool water tank.

[0029] In this embodiment, buckles 14 are further provided at both ends of the box body 1, and the buckles 14 can be used to conveniently and quickly install or move the entire device.

[0030] like Figure 2-3 As shown, the filter unit 2 includes a rectangular bottom plate 21, a pair of side edges of the rectangular bottom plate 21 are vertically provided with filter plates 22, and the other pair of side edges are vertically provided with a left plate 23 and a right plate 24 of the same structure. The sides of the filter plate 22, the left plate 23, and the right plate 24 are connected to each other and together with the rectangular bottom plate 21 form a filter area; filter holes are provided on the rectangular bottom plate 21 and the filter plate 22; the height of the left plate 23 and the right plate 24 is greater than the height of the filter plate 22.

[0031] The filter unit 2 also includes a paper roll core shaft 25, a motor core shaft 26 and several support shafts 27. The paper roll core shaft 25 and the support shaft 27 are vertically arranged between the left side plate 23 and the right side plate 24. The motor core shaft 26 is rotatably arranged between the left side plate 23 and the right side plate 24, and the motor core shaft 26 is parallel to the paper roll core shaft 25 and the support shaft 27.

[0032] A motor bracket 28 is provided on the right side plate 24, and a motor 29 is provided on the motor bracket 28. The motor 29 is connected to the motor core shaft 26 and is used to drive the motor core shaft 26 to rotate; a filter paper 30 is provided on the paper roll core shaft 25, and one end of the filter paper 30 is connected to the motor core shaft 26 by passing through several support rods 27, and the width of the filter paper 30 is the same as the distance between the left side plate 23 and the right side plate 24.

[0033] In this embodiment, the filter paper 30 is sleeved on the paper roll core shaft 25, and one end of the filter paper 30 is passed around several support rods 27 in sequence and connected to the motor core shaft 26. Under the action of the several support rods 27, the filter paper 30 and the left side plate 23 and the right side plate 24 form a stable area.

[0034] A waist-shaped hole 31 is formed on the right side plate 24 , and the length direction of the waist-shaped hole 31 is consistent with the height direction of the right side plate 24 ; a water inlet pipe 32 is provided at the upper end of the waist-shaped hole 31 .

[0035] In this embodiment, the water outlet of the water inlet pipe is set in the machine tool water tank. After passing through the water inlet pipe, the machining fluid all flows into the area surrounded by the filter paper 30 and the left side plate 23 and the right side plate 24.

[0036] The right side plate 24 is also provided with a movable baffle 33, which has a U-shaped groove. The shape of the U-shaped groove is the same as the bottom end shape of the waist-shaped hole 31. Therefore, the movable baffle 33 can adjust the size of the waist-shaped hole 31 when moving upward, and can adjust the liquid level in the filter unit.

[0037] The filter unit 2 also includes a water level gauge 34 for monitoring the water level in the filter area. Preferably, the water level gauge is a float gauge. The right side panel is also provided with a strip-shaped hole 35. The float gauge is disposed in the strip-shaped hole 35 to monitor the water level in the filter unit 2. When the water level changes, the motor can be manually controlled to replace the filter paper.

[0038] As another embodiment of the present invention, the wire cutting machine water tank pre-filter device may further include a control unit, and the water level meter and the motor are both connected to the control unit. When the water level meter detects that the water level of the filter unit changes, it sends a signal to the control unit, and the control unit controls the drive motor according to the received signal.

[0039] On the other hand, the filtering device of the present invention can also be used to filter sewage in other devices, such as a perforator or a fish tank.

[0040] When the wire cutting machine water tank pre-filter device of the present invention is in use, the processing fluid in the machine tool water tank enters the filter unit through the water inlet pipe, is filtered by the filter paper, enters the first tank body from the sieve holes on the rectangular bottom plate and the filter plate, and then flows into the second tank body through the connecting pipe. The filtered processing fluid undergoes secondary precipitation in the second tank body, and is discharged through the water outlet pipe of the water tank after precipitation is completed.

[0041] When the filter paper absorbs a large amount of impurities, water blockage will occur. At this time, when the water level gauge detects that the water level in the filter unit exceeds the set value, the drive motor starts and drives the motor core shaft to rotate to reel in the clogged filter paper; after normal filtration, when the water level drops, the drive motor stops rotating.

[0042] Therefore, the wire cutting machine water tank pre-filter device of the present invention can filter the processing fluid through relatively low-priced filter paper, and its maintenance cost is low. Moreover, the filter paper can be replaced manually or automatically through the setting of the water level meter and the drive motor. It is simple to operate and has high processing efficiency. In addition, the mesh size of the filter paper can be selected according to needs, so that the filtering effect is more excellent.

[0043] Example 2

[0044] Different from Example 1, this embodiment can perform secondary filtration on the processing fluid.

[0045] like Figure 4 As shown, the wire cutting machine water tank pre-filter device further includes a second filter unit 3 , which is arranged in the second tank body and has the same structure as the filter unit 2 .

[0046] Specifically, the second filter unit 3 is arranged in the second pool body, and the water outlet end of the connecting pipe 12 extends into the interior of the second filter unit 2 from the waist-shaped hole 31 on the side plate of the second filter unit 2, thereby introducing the processing fluid filtered by the filter unit 2 into the second filter unit 3 for secondary filtration.

[0047] The order of the above embodiments is only for the convenience of description and does not represent the superiority or inferiority of the embodiments.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
