Description

Technical Field

[0001] The utility model belongs to the technical field of machining waste liquid treatment, and particularly relates to a waste liquid separation device for machine tool machining. Background Art

[0002] When a machine tool processes a metal blank, it is necessary to spray cutting fluid on the part where the cutter head and the blank contact (i.e., the processing part). After passing through the processing part, the cutting fluid will drip onto the machine tool and eventually flow into the water storage tank to form waste liquid. Since a lot of fine chips will be generated during the processing, the waste liquid flowing into the water storage tank is bound to be mixed with a lot of fine chips.

[0024] Compared with the prior art, the utility model has the following beneficial effects:

[0025] The utility model provides a waste liquid separation device for machine tool processing, which comprises a water storage tank, a square tube, a slag blocking plate and a slag lifting plate. The square tube has a first end that penetrates through and a second end that is closed. The first end is overlapped with the box opening of the water storage tank so that the square tube is connected with the water storage tank. The outer bottom wall of the square tube is provided with a supporting leg, so that the square tube is supported by the supporting leg and the water storage tank.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0041] Embodiment 1:

[0042] like Figure 1-Figure 9 As shown, the waste liquid separation device for machine tool processing provided in this embodiment includes a water storage tank 1, a square tube 2, a slag blocking plate 4 and a slag lifting plate 9, wherein:

[0043] The square tube 2 is a straight tube with a square longitudinal section. The square tube 2 has a first end that penetrates through and a second end that is closed. The first end is overlapped with the box opening of the water storage tank 1 so that the square tube 2 is connected to the water storage tank 1. The outer bottom wall of the square tube 2 is provided with a support leg 3, so that the support leg 3 and the water storage tank 1 are used to support the square tube 2. The top wall of the square tube 2 is provided with a slag removal port and a water inlet. The waste liquid (i.e., cutting fluid) used for machine tool processing enters the square tube 2 from the water inlet. The water inlet is located near the second end, and the slag removal port is located between the water inlet and the first end. It should be noted that the slag removal port extends from the front side wall of the square tube 2 to the rear side wall thereof.

[0044] The slag blocking plate 4 is a stainless steel plate, which is adapted to the above-mentioned slag removal port, and is inserted into the above-mentioned slag removal port by sliding up and down, and the slag blocking plate 4 is vertically arranged, and an upper horizontal plate 5 is integrally formed on the top of the slag blocking plate 4, and a locking assembly is provided between the upper horizontal plate 5 and the outer wall of the square tube 2. With the help of the locking assembly, the upper horizontal plate 5 and the slag blocking plate 4 can be locked on the outer wall of the square tube 2.

[0045] The slag lifting plate 9 is integrally formed at the bottom of the slag blocking plate 4, and is located on the side close to the second end, and both the slag lifting plate 9 and the slag blocking plate 4 are provided with a plurality of fine holes for waste liquid to pass through. The slag lifting plate 9 is also adapted to the slag removal port, that is, the slag lifting plate 9 can also enter and exit the slag removal port.

[0046] Through the above structure, the cutting fluid (that is, waste liquid) used for machine tool processing enters the above square tube 2 from the water inlet, and then flows from the second end of the square tube 2 to the first end and finally flows into the above water storage tank 1 from the first end for standing. When the waste liquid flows in the square tube 2, it will pass through the slag blocking plate 4, and the slag blocking plate 4 will block the fine chips in the waste liquid. The waste liquid passes through the fine holes on the slag blocking plate 4, and some of the blocked fine chips fall on the slag lifting plate 9 and accumulate, and the other part hangs on the slag blocking plate 4. When the fine chips need to be removed, the above locking assembly is unlocked, and then the upper cross plate 5 is pulled up, so that the slag blocking plate 4 and the slag lifting plate 9 are moved up to the slag removal port, and then the worker removes the fine chips accumulated on the slag lifting plate 9 and the fine chips hanging on the slag blocking plate 4, and finally lowers the slag blocking plate 4 and the slag lifting plate 9 into the square tube 2 and locks the above locking assembly. The operation is simple and convenient, and the filtered fine chips can be easily removed. Optionally, a handle 13 is provided on the top surface of the upper horizontal board 5 to facilitate workers to lift the upper horizontal board 5 .

[0047] The device uses the slag retaining plate 4 to filter out fine chips in the waste liquid, and uses the slag lifting plate 9 and the slag retaining plate 4 to lift the filtered fine chips away from the square tube 2, thereby separating most of the fine chips in the waste liquid. The waste liquid flowing into the water storage tank 1 is allowed to stand in the water storage tank 1, and a small amount of fine chips that are not filtered by the slag retaining plate 4 are deposited at the bottom of the water storage tank 1. In this way, the device can better separate the fine chips in the waste liquid. It is a purely mechanical structure, and does not use electrical equipment such as motors. It has a simple structure and low cost, and is more suitable for removing fine chips from waste liquid used for machine tool processing.

[0048] It is worth noting that when the slag baffle plate 4 is placed in the square tube 2 to block the fine debris in the waste liquid, the locking assembly locks the slag baffle plate 4 and the horizontal plate on the square tube 2, and the slag lifting plate 9 is now in close contact with the inner bottom wall of the square tube 2; when it is necessary to lift the slag baffle plate 4 out of the square tube 2, the locking assembly is unlocked. It is easy to understand that since the water flow in the square tube 2 has a driving effect on the slag baffle plate 4, when the slag baffle plate 4 is placed inside the square tube 2, it is necessary to use the locking assembly to lock it on the square tube 2 so that the slag baffle plate 4 can be stably placed in the flowing water. In addition, the slag lifting plate 9, the slag baffle plate 4 and the upper horizontal plate 5 form a Z-shaped slag removal assembly.

[0049] Optionally, a ring 10 surrounding the slag removal port is integrally formed on the top surface of the square tube 2. When the slag lifting plate 9 is in close contact with the inner bottom wall of the square tube 2, the upper horizontal plate 5 is overlapped on the ring 10. The provision of the ring 10 makes it more difficult for the waste liquid in the square tube 2 to splash out of the square tube 2. Moreover, when the slag lifting plate 9 is lifted from the square tube 2, the slag lifting plate 9 will directly enter the square tube 2. At this time, if the slag lifting plate 9 is kept stationary, that is, the slag lifting plate 9 is placed in the square tube 2, the fine debris on the slag lifting plate 9 can also be drained. After the drainage is completed, the upper horizontal plate 5, the slag blocking plate 4 and the slag lifting plate 9 can be further lifted. More preferably, a cover plate can be overlapped on the top of the ring 10 to cover the top of the ring 10.

[0050] Optionally, the locking assembly includes a first stud 6 and a locking nut 7, the first stud 6 is vertically welded and fixed on the top surface of the square tube 2, the upper horizontal plate 5 is provided with a through hole corresponding to the first stud 6, and when the locking assembly is locked, the first stud 6 passes through the through hole and is screwed with the locking nut 7. When the locking assembly is unlocked, it is only necessary to unscrew the locking nut 7 from the first stud 6, which is simple and convenient to operate, simple in structure, and low in cost.

[0051] In order to make the slag blocking plate 4 and the slag lifting plate 9 rise and fall smoothly, in this embodiment, a guide assembly is provided between the upper horizontal plate 5 and the square tube 2, and the upper horizontal plate 5 is guided to move up and down relative to the square tube 2 by means of the guide assembly, thereby guiding the slag blocking plate 4 and the slag lifting plate 9 to move up and down. Specifically, the guide assembly includes two guide rods 8, which are vertically welded to the top surface of the square tube 2, and two guide holes are provided on the upper horizontal plate 5, which are adapted to the guide rods 8, and the two guide rods 8 are respectively inserted into the two guide holes to slide up and down.

[0052] More preferably, a connecting rod 11 is bolted between the top ends of the two guide rods 8. Specifically, a screw hole is provided at the top end of each guide rod 8, and the connecting rod 11 is provided with two blind holes. The bolts pass through the blind holes and are screwed to the screw holes, so that the connecting rod 11 is detachably connected between the two guide rods 8. This not only increases the structural strength, but also allows the connecting rod 11 to limit the upward movement height of the upper cross plate 5. Optionally, when the upper cross plate 5 moves up to abut against the connecting rod 11, the top surface of the slag lifting plate 9 moves up to be flush with the top end of the ring 10.

[0053] A second stud 12 corresponding to the through hole on the upper horizontal plate 5 is welded and fixed on the bottom surface of the connecting rod 11. Specifically, the second stud 12 is coaxial with the first stud 6, and the second stud 12 is located directly above the first stud 6. In this way, when the upper horizontal plate 5, the slag baffle plate 4 and the slag lifting plate 9 are lifted, the first stud 6 comes out of the through hole, and then after being lifted to a certain height, the second stud 12 is inserted into the through hole from above. When the slag lifting plate 9 is lifted into the ring 10, the bottom end of the second stud 12 extends out of the through hole. At this time, the locking nut 7 is screwed onto the second stud 12, and the upper horizontal plate 5 is supported from below by the locking nut 7, so that the slag lifting plate 9 is firmly placed in the ring 10, so as to drain the fine debris on the slag lifting plate 9 and the slag baffle plate 4, which is in a draining state at this time. When the upper horizontal plate 5 moves up to abut against the connecting rod 11, the top surface of the slag lifting plate 9 is flush with the top of the ring 10, and the locking nut 7 screwed on the second stud 12 can be screwed to make the locking nut 7 bear under the upper horizontal rod. This is the slag removal state. When the slag blocking plate 4 and the slag lifting plate 9 are both located in the square tube 2 and the slag lifting plate 9 is in contact with the inner bottom wall of the square tube 2, it is the slag filtering state.

[0054] Optionally, a water inlet hopper 14 corresponding to the water inlet is also installed on the top surface of the square tube 2 to collect waste liquid (i.e., cutting fluid) used for machine tool processing, so that more waste liquid can enter the water inlet. More preferably, a guide ramp is installed in the square tube 2, and the guide ramp is directly below the water inlet. The guide ramp is inclined toward the first end of the square tube 2. After the waste liquid enters the water inlet from the water inlet hopper 14, it falls on the guide ramp. The guide ramp guides the waste liquid so that the waste liquid can flow more smoothly to the slag baffle 4 and the first end of the square tube 2. A reinforcing column 16 is provided between the guide ramp and the inner bottom wall of the square tube 2 to enhance the load-bearing capacity of the guide ramp.

[0055] Optionally, a guide slope 17 is provided on one side of the slag stripping plate 9 close to the second end of the square tube 2. Since fine chips flow from the second end of the square tube 2 to the slag blocking plate 4 and the slag stripping plate 9, the setting of the guide slope 17 is more conducive to the waste liquid flushing the fine chips to the slag stripping plate 9.

[0056] Optionally, in the present embodiment, the number of the above-mentioned slag removal ports opened on the top surface of the above-mentioned square tube 2 is two, and the two slag removal ports are sequentially distributed between the first end and the second end of the square tube 2, and one of the above-mentioned slag removal components is installed in each slag removal port. In this way, when one of the slag removal components is lifted up to remove fine debris filtered thereon, the other slag removal component needs to be placed in the square tube 2. In this way, the fine debris on the two slag removal components can be switched back and forth to be removed. Based on this, it can be ensured that at least one of the above-mentioned slag removal components is installed in the square tube 2 at any time, so the device can remove part of the fine debris separated from the waste liquid when there is waste liquid flowing in the square tube 2. Moreover, the provision of the two slag removal components can also more effectively filter out the fine debris in the waste liquid for removal.

[0057] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
