Description

Technical Field

[0001] The utility model relates to the technical field of silicon wafer cutting machines, in particular to a filter press. Background Art

[0002] In the prior art, the cutting liquid is recovered and recycled when the silicon wafer is cut. Specifically, the cutting liquid after wire cutting contains a large amount of silicon powder. After being filtered by a filter press, the cutting liquid can be divided into clear liquid and turbid liquid. Among them, the clear liquid enters the recycling water tank and is used as recycling water. Since the turbid liquid will cause the recycling water to be polluted after entering the recycling water tank, it is necessary to distinguish the turbid liquid from the clear liquid to prevent the turbid liquid from entering the recycling water tank.

[0003] At present, the distinction between clear liquid and turbid liquid is done manually. When clear liquid flows out of the outlet pipe, the worker puts the outlet pipe into the clear liquid tank; when turbid liquid flows out of the outlet pipe, the worker puts it into the turbid liquid tank. However, since the outlet pipe flows out turbid liquid or clear liquid randomly, the worker cannot switch in time, and each worker has different standards for distinguishing turbid liquid, which makes it easy for turbid liquid to enter the reuse water tank, causing adverse effects on production, increasing the workload of personnel, and reducing production efficiency.

[0021] Reference below Figure 1 A filter press 100 according to an embodiment of the present invention is described.

[0022] like Figure 1 As shown, the filter press 100 according to the embodiment of the utility model includes a compression device 1, a clear liquid tank 2, a turbid liquid tank 3 and a diversion device 4.

[0023] Specifically, the compression device 1 is used to compress waste liquid, and at least one liquid outlet pipe 11 is provided on the compression device 1. The clear liquid tank 2 and the turbid liquid tank 3 are both located below the liquid outlet pipe 11. The diversion device 4 includes a turbidity sensor 41 and a motion mechanism 42. The turbidity sensor 41 is provided on the liquid outlet pipe 11, and is used to detect the turbidity of the liquid flowing out of the liquid outlet pipe 11. The motion mechanism 42 is connected to the liquid outlet pipe 11, and the motion mechanism 42 can be switched between a push-out state and a retracted state. When the liquid flowing out of the liquid outlet pipe 11 is turbid liquid, the motion mechanism 42 switches to the push-out state, and drives the liquid outlet pipe 11 to be opposite to the turbid liquid tank 3; when the liquid flowing out of the liquid outlet pipe 11 is clear liquid, the motion mechanism 42 switches to the retracted state, and drives the liquid outlet pipe 11 to be opposite to the clear liquid tank 2.

[0024] For example, in Figure 1In the example, the liquid outlet pipe 11 is arranged on one side of the compression device 1 in the width direction, and the liquid outlet pipe 11 is led out from the lower side of the compression device 1. The liquid outlet pipe 11 extends to the top of the clear liquid tank 2 and the turbid liquid tank 3, so as to facilitate the liquid flowing out of the liquid outlet pipe 11 to flow into the clear liquid tank 2 or the turbid liquid tank 3. The turbidity sensor 41 is arranged on the side of the liquid outlet pipe 11 away from the compression device 1, so that when the liquid flows out of the liquid outlet pipe 11, the turbidity sensor 41 can detect the turbidity of the liquid in time. The motion mechanism 42 is connected to the liquid outlet pipe 11 and is located between the turbidity sensor 41 and the compression device 1. The motion mechanism 42 can drive the liquid outlet pipe 11 to move above the clear liquid tank 2 and above the turbid liquid tank 3, so that the liquid outlet pipe 11 can switch between being opposite to the clear liquid tank 2 and being opposite to the turbid liquid tank 3, so as to facilitate the clear liquid and the turbid liquid to flow into the corresponding tanks respectively.

[0025] Specifically, when the turbidity sensor 41 detects that the liquid flowing out of the liquid outlet pipe 11 is turbid liquid, the motion mechanism 42 switches to the push-out state, so that the liquid outlet pipe 11 is opposite to the turbid liquid tank 3, and the turbid liquid can flow into the turbid liquid tank 3. When the turbidity sensor 41 detects that the liquid flowing out of the liquid outlet pipe 11 is clear liquid, the motion mechanism 42 switches to the retracted state, so that the liquid outlet pipe 11 is opposite to the clear liquid tank 2, and the clear liquid can flow into the clear liquid tank 2. In this way, the automatic diversion of clear liquid and turbid liquid is realized, and manual operation is no longer required, and a unified standard is provided for distinguishing clear liquid from turbid liquid.

[0026] When the turbidity is greater than 100 NTU, the liquid flowing out of the liquid outlet pipe 11 is considered to be turbid liquid; when the turbidity is less than 100 NTU, the liquid flowing out of the liquid outlet pipe 11 is considered to be clear liquid. In addition, the liquid outlet pipe 11 is usually opposite to the turbid liquid tank 3 to prevent the turbidity sensor 41 from malfunctioning and failing to detect the turbidity of the liquid, thereby preventing the turbid liquid from flowing into the clear liquid tank 2 and causing the clear liquid tank 2 to be contaminated.

[0027] Thus, the diverter device 4 can separate the liquid compressed by the compression device 1 and recover the turbid liquid and the clear liquid respectively, thus realizing the diverter automation, saving labor costs, improving work efficiency, and being conducive to a virtuous cycle of production.

[0028] According to the filter press 100 of the embodiment of the utility model, by providing the diverting device 4, the liquid compressed by the compression device 1 can be detected and distinguished into clear liquid and turbid liquid, and the clear liquid and turbid liquid can be automatically diverted and recovered separately. Therefore, compared with the traditional filter press, the automatic diversion and recovery of the clear liquid and turbid liquid is realized, the labor cost is saved, the work efficiency is improved, and it is conducive to the virtuous cycle of production.

[0029] According to some embodiments of the present invention, a connecting member 5 is provided between the motion mechanism 42 and the liquid outlet pipe 11, one end of the connecting member 5 is connected to the liquid outlet pipe 11, and the other end of the connecting member 5 is rotatably connected to the motion mechanism 42. Figure 1, the motion mechanism 42 is connected to the liquid outlet pipe 11 through the connector 5. When the motion mechanism 42 switches between the push-out state and the retracted state, the connector 5 can rotate around the connection point between the connector 5 and the motion mechanism 42, so that the end of the connector 5 connected to the liquid outlet pipe 11 can pull the liquid outlet pipe 11 to move above the clear liquid tank 2 and above the turbid liquid tank 3, so that the liquid outlet pipe 11 can be opposite to the clear liquid tank 2 and the turbid liquid tank 3 respectively, so as to facilitate the liquid to flow into the corresponding tank. In this way, the liquid outlet pipe 11 can be flexibly adjusted, so that after the turbidity sensor 41 detects the turbidity of the liquid, the liquid can flow into the corresponding tank, saving labor costs and improving work efficiency.

[0030] According to some embodiments of the utility model, the motion mechanism 42 includes an air pump 421 and a cylinder 422. The air pump 421 is arranged below the compression device 1. One end of the cylinder 422 is connected to the liquid outlet pipe 11, and the other end of the cylinder 422 is connected to the air pump 421. When the motion mechanism 42 is switched to the push state, the cylinder 422 drives the liquid outlet pipe 11 to face the turbid liquid tank 3. When the motion mechanism 42 is switched to the retract state, the cylinder 422 drives the liquid outlet pipe 11 to face the clear liquid tank 2. Figure 1 As shown, the cylinder 422 is located between the air pump 421 and the liquid outlet pipe 11. The air pump 421 provides power to the cylinder 422 through compressed air, so that the cylinder 422 switches between the push-out state and the retracted state, thereby controlling the movement of the liquid outlet pipe 11. This arrangement enables the motion mechanism 42 to switch between the push-out state and the retracted state, thereby facilitating the control of the movement of the liquid outlet pipe 11, improving work efficiency, and enabling the liquid diversion to be completed automatically, saving labor costs.

[0031] Furthermore, the motion mechanism 42 further includes a controller 423 and a solenoid valve 424. The controller 423 is electrically connected to the turbidity sensor 41. The solenoid valve 424 is disposed between the air pump 421 and the cylinder 422, and the solenoid valve 424 is electrically connected to the controller 423. Figure 1 In the example, the controller 423 is located at one end of the liquid outlet pipe 11 adjacent to the compression device 1, and the controller 423 can receive an electrical signal from the turbidity sensor 41, that is, after the turbidity sensor 41 detects the turbidity of the liquid, it transmits the detection result to the controller 423. The controller 423 can control the opening and closing of the electromagnetic valve 424, and the electromagnetic valve 424 controls the connection between the air pump 421 and the cylinder 422.

[0032] When the solenoid valve 424 is open, the air pump 421 can provide power to the cylinder 422, and when the solenoid valve 424 is closed, the air pump 421 cannot transmit power to the cylinder 422. When the turbidity sensor 41 detects that the liquid flowing out of the liquid outlet pipe 11 is clear liquid, the detection result signal can be transmitted to the controller 423, and the controller 423 controls the solenoid valve 424 to open, so that the motion mechanism 42 can be switched to the retracted state, so that the liquid outlet pipe 11 is opposite to the clear liquid tank 2, so that the clear liquid flows into the clear liquid tank 2. When the turbidity sensor 41 detects that the liquid flowing out of the liquid outlet pipe 11 is turbid liquid, the detection structure signal can be transmitted to the controller 423, and the controller 423 controls the solenoid valve 424 to open, so that the motion mechanism 42 can be switched to the push-out state, so that the liquid outlet pipe 11 is opposite to the turbid liquid tank 3, so that the turbid liquid flows into the turbid liquid tank 3.

[0033] Such an arrangement realizes automatic diversion of the liquid flowing out of the liquid outlet pipe 11, saves labor costs, improves work efficiency, and can prevent the clear liquid from being contaminated by the turbid liquid, thereby improving the safety of the production process.

[0034] According to some embodiments of the present invention, referring to Figure 1 The turbidity sensor 41 is arranged at the free end of the liquid outlet pipe 11. Such arrangement improves the detection accuracy of the turbidity sensor 41, is conducive to the turbidity sensor 41 to detect the liquid flowing out of the liquid outlet pipe 11 in time, and improves the working efficiency of the diversion device 4.

[0035] According to some embodiments of the present invention, the filter press 100 further includes a fixing member 6, which is connected to the liquid outlet pipe 11, and is located on a side of the liquid outlet pipe 11 away from the motion mechanism 42, and a turbidity sensor 41 is provided on the fixing member 6. Figure 1 In the example, the fixing member 6 is located at the free end of the liquid outlet pipe 11, one end of the fixing member 6 is connected to the liquid outlet pipe 11, and the other end of the fixing member 6 is connected to the turbidity sensor 41. By providing the fixing member 6, the distance between the turbidity sensor 41 and the liquid outlet pipe 11 can be fixed to prevent the turbidity sensor 41 from being displaced at will, and ensure that the turbidity sensor 41 can detect the liquid flowing out of the liquid outlet pipe 11 in time, so as to ensure the normal operation of the diversion device 4.

[0036] Furthermore, the fixing member 6 includes a first fixing section 61 and a second fixing section 62 connected to each other, the first fixing section 61 extends in a direction away from the liquid outlet pipe 11, the first fixing section 61 is connected to the liquid outlet pipe 11, and the second fixing section 62 extends in a direction away from the compression device 1, and the second fixing section 62 is provided with a turbidity sensor 41. Figure 1As shown, the first fixing section 61 and the second fixing section 62 are perpendicular to each other, and the shape formed by the first fixing section 61 and the second fixing section 62 is L-shaped. One end of the first fixing section 61 is connected to the liquid outlet pipe 11, the other end of the first fixing section 61 is connected to the second fixing section 62, and the free end of the second fixing section 62 is connected to the turbidity sensor 41.

[0037] Such an arrangement fixes the turbidity sensor 41 and the liquid outlet pipe 11, prevents the liquid outlet pipe 11 and the turbidity sensor 41 from displacement, avoids contamination of the clear liquid in the clear liquid tank 2, and ensures that the turbidity sensor 41 can normally detect the turbidity of the liquid flowing out of the liquid outlet pipe 11.

[0038] According to some embodiments of the present invention, the liquid outlet pipe 11 includes a first pipe section 111 and a second pipe section 112 connected to each other, the first pipe section 111 is connected to the compression device 1, the controller 423 is arranged in the first pipe section 111, the cylinder 422 is connected to the second pipe section 112, and the second pipe section 112 is a hose. Figure 1 The first pipe section 111 is in a Z-shape, and the second pipe section 112 is connected to the end of the first pipe section 111 away from the compression device 1. The controller 423 is arranged on the side of the first pipe section 111 adjacent to the compression device 1, and the cylinder 422 is connected to the middle of the second pipe section 112. The motion mechanism 42 controls the second pipe section 112 by switching between the push state and the switch state, so that the second pipe section 112 can switch between the clear liquid tank 2 and the turbid liquid tank 3, so that the liquid flows into the corresponding tank. The second pipe section 112 is a hose, which facilitates the movement of the second pipe section 112 by the motion mechanism 42, thereby improving the working efficiency.

[0039] According to some embodiments of the present invention, there are multiple cylinders 422 and multiple liquid outlet pipes 11. In the description of the present invention, "multiple" means two or more. Multiple liquid outlet pipes 11 are spaced apart along the circumference of the compression device 1, and multiple cylinders 422 are connected to the same air pump 421. Figure 1 As shown, the number of cylinders 422 and liquid outlet pipes 11 can be two, and the two liquid outlet pipes 11 are respectively located on both sides of the width direction of the compression device 1, and the two cylinders 422 are respectively located on both sides of the air pump 421, and the cylinders 422 and the liquid outlet pipes 11 are connected one by one. Such an arrangement improves the liquid outlet efficiency of the compression device 1, and the liquid outlet pipes 11 on both sides and the diverting device 4 can divert at the same time, thereby improving work efficiency and reducing production costs.
