Specific implementation

[0032] In order to make the person in the art better understand the technical scheme in the utility model, the technical scheme in the embodiment of the utility model will be described clearly and completely below in combination with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the utility model.

[0033] As Figures 1 to 5 shown, a press filter filtrate timing sampling assembly in an embodiment of the utility model, including press filter main body 1, sampling mechanism 2.

[0034] Among them, the press filter main body 1 is connected with liquid inlet pipe 101 and several liquid outlet branch pipes 102, and several liquid outlet branch pipes 102 are connected with liquid outlet main pipe 103 through pipeline, slurry enters into press filter main body 1 from liquid inlet pipe 101, after being filtered in press filter main body 1, is discharged through several liquid outlet branch pipes 102, and is finally discharged to next process in liquid outlet main pipe 103.

[0035] In addition, a cross-section pipe 104 is connected to the main liquid outlet pipe 103, which is connected to a sampling pipe 105. A solenoid timing valve 106 is installed on the sampling pipe 105. When the solenoid timing valve 106 opens, the filtrate flowing in the main liquid outlet pipe 103 is discharged through the sampling pipe 105, thereby completing filtrate sampling to determine changes in the filtrate water quality.

[0036] Preferably, the electromagnetic timing valve 106 is a commercially available product that can be purchased and used directly. By setting the electromagnetic timing valve 106, the sampling amount of the filtrate in each sampling cup 203 can be ensured to be the same, and the probability of the filtrate overflowing the sampling cup 203 can also be reduced, thereby ensuring the sampling quality.

[0037] Specifically, a first solenoid valve 107 is installed on the liquid outlet manifold 103. The first solenoid valve 107 is located on the side of the cross-section pipe 104 away from the filter press body 1. The first solenoid valve 107 is used to control the on / off state of the liquid outlet manifold 103. When the turbidity value of the filtrate in the liquid outlet manifold 103 is lower than the monitoring value set by the turbidity meter 3, the first solenoid valve 107 opens, and the filtrate can continue to be transported through the liquid outlet manifold 103 to the next process. At the same time, the filtrate sampling work can also be completed.

[0038] When the turbidity value of the filtrate in the liquid outlet main pipe 103 is higher than the monitoring value set by the turbidity meter 3, the first solenoid valve 107 is closed and the second solenoid valve 210 is opened. The filtrate in the liquid outlet main pipe 103 can enter the temporary storage chamber 208 through the connecting pipe 209, and no sampling work will be performed.

[0039] In addition, a control box is installed on the side wall of the filter press body 1, and the electromagnetic timing valve 106 is electrically connected to the control box. The control box can control the operation of the electromagnetic timing valve 106, the first electromagnetic valve 107, the motor 206, and the submersible pump 211, and can also receive the monitoring signal sent by the turbidity meter 3.

[0040] In actual use, the staff can program corresponding logic language into the control box, such as the opening time of the electromagnetic timing valve 106 each time, the rotation frequency and rotation angle of the motor 206, the turbidity value monitored by the turbidity meter 3, etc., and use the logic language to control the operation of the entire equipment.

[0041] like Figures 1 to 5 As shown, the sampling mechanism 2 is provided on one side of the filter press body 1. If the turbidity value of the filtrate in the liquid outlet main pipe 103 is continuously lower than the monitoring value set by the turbidity meter 3, the sampling mechanism 2 can be used to regularly sample the filtrate in the liquid outlet main pipe 103 to determine the changes in the water quality of the filtrate.

[0042] The sampling mechanism 2 comprises a sampling table 201, and the sampling table 201 is rotationally connected with a rotating disc 202. The rotating disc 202 is provided with a plurality of storage grooves and a plurality of label grooves 204, and the plurality of storage grooves correspond to the plurality of label grooves 204 one by one. The staff can place a sampling cup 203 in the storage groove, and at the same time, a label is pasted in the corresponding label groove 204, so as to indicate the sampling cup 203. The label content can be a label number.

[0043] In addition, the sampling cup 203 is arranged in the storage groove, and the sampling cup 203 corresponds to the sampling pipe 105. The sampling cup 203 can be used for sampling, so as to analyze the change of the filtrate water quality.

[0044] Specifically, the sampling table 201 is provided with a mounting cavity 205 for accommodating a motor 206 and a control unit 207. The sampling table 201 is provided with a driving mechanism connected with the rotating disc 202. The driving mechanism is used for controlling the rotation of the rotating disc 202, so that the sampling cup 203 can be sequentially conveyed to the lower side of the sampling pipe 105 according to the set frequency, so as to sample the filtrate.

[0045] As shown in Figures 1 to 5 The driving mechanism comprises the motor 206, and the output end of the motor 206 is connected with the rotating disc 202. When the motor 206 operates, the motor 206 can drive the rotating disc 202 to rotate, so that the sampling cup 203 in the storage groove can be sequentially conveyed to the lower side of the sampling pipe 105, so as to perform the timed sampling.

[0046] The mounting cavity 205 is provided with the control unit 207, and the control unit 207 is electrically connected with the motor 206 and a control box. The control box can control the operation state of the motor 206 through the control unit 207, including the operation frequency of the motor 206 and the rotation angle of each time.

[0047] For example, if the number of sampling cups 203 is 12, and the change of the filtrate water quality in 1 hour needs to be analyzed, the motor 206 needs to be controlled to rotate every 5 minutes, and the rotation angle of the motor 206 is 30° each time.

[0048] For another example, if the number of sampling cups 203 is 10, and the change of the filtrate water quality in 2 hours needs to be analyzed, the motor 206 needs to be controlled to rotate every 12 minutes, and the rotation angle of the motor 206 is 36° each time. Specifically, the sampling interval can be determined according to the experimental or production needs.

[0049] In addition, a temporary storage chamber 208 is provided within the sampling station 201 for temporarily storing filtrate. A connecting tube 209 is connected to the cross-section pipe 104, one end of which is located within the temporary storage chamber 208. If the turbidity value of the filtrate in the main outlet pipe 103 exceeds the monitoring value set by the turbidity meter 3, the filtrate in the main outlet pipe 103 can enter the temporary storage chamber 208 through the connecting tube 209 for temporary storage, thereby preventing excessive liquid pressure within the filter press body 1.

[0050] Specifically, a second solenoid valve 210 is installed on the connecting pipe 209, and the second solenoid valve 210 is used to control the opening and closing of the connecting pipe 209. The second solenoid valve 210 and the first solenoid valve 107 are both electrically connected to the control box, and the control of the second solenoid valve 210 and the first solenoid valve 107 can be achieved through the control box.

[0051] like Figures 1 to 5 As shown, a submersible pump 211 is installed in the temporary storage chamber 208. A liquid extraction pipe and a return pipe 212 are connected to the submersible pump 211. One end of the return pipe 212 is connected to the liquid inlet pipe 101. When the submersible pump 211 is running, the submersible pump 211 can extract the filtrate in the temporary storage chamber 208 through the liquid extraction pipe and then transfer the filtrate to the liquid inlet pipe 101 through the return pipe 212, thereby circulating the filtrate with a higher turbidity value.

[0052] A one-way valve 213 is installed on the reflux pipe 212 , so that the liquid in the liquid inlet pipe 101 is not likely to flow back through the reflux pipe 212 .

[0053] In addition, an alarm is installed on the side wall of the sampling station 201 and is electrically connected to the control box. When the sampling cups 203 have all completed sampling, the alarm can sound an alarm to remind the staff. Before that, the staff can carry out other tasks, so that the staff does not need to constantly pay attention to the sampling time, which can reduce the burden on the staff to a certain extent.

[0054] Of course, when the turbidity meter 3 detects that the turbidity value of the filtrate in the liquid outlet main pipe 103 is higher than the monitoring value, the alarm can also be controlled to sound an alarm to remind the staff to check in time to eliminate the fault.

[0055] like Figures 1 to 5 As shown, a turbidity meter 3 is installed on the liquid outlet manifold 103 and is electrically connected to the control box. The turbidity meter 3 is used to monitor the turbidity of the filtrate in the liquid outlet manifold 103. If the turbidity value of the filtrate is lower than the set monitoring value, the filtrate can continue to be transported through the liquid outlet manifold 103 and enter the next process. If the turbidity value of the filtrate is higher than the set monitoring value, the filtrate can be temporarily transported to the temporary storage chamber 208.

[0056] In use, the slurry enters the filter press body 1 from the inlet pipe 101, and is discharged through the outlet branch pipes 102 under the filtering action of the filter press body 1, and is then gathered in the outlet main pipe 103 and discharged to the next process. The turbidity of the filtrate flowing in the outlet main pipe 103 can be monitored by the turbidity meter 3 on the outlet main pipe 103.

[0057] If the turbidity value of the filtrate is lower than the monitoring value, the filtrate will continue to be conveyed through the outlet main pipe 103 and enter the next process. At the same time, the sampling mechanism 2 can be used to take samples of the filtrate at regular intervals to determine the changes in the water quality of the filtrate.

[0058] Specifically, before sampling, a plurality of sampling cups 203 are placed in the plurality of holding grooves, and corresponding labels are pasted in the label grooves 204. When sampling, the electromagnetic timing valve 106 on the sampling pipe 105 is opened under the control of the control box, and part of the filtrate in the outlet main pipe 103 enters the sampling cup 203 through the sampling pipe 105. The control box controls the electromagnetic timing valve 106 to close, and then controls the motor 206 to operate, so that the rotating disc 202 is driven to rotate, so that the sampling cup 203 that has completed sampling rotates, and another empty sampling cup 203 rotates to be directly below the sampling pipe 105. When the electromagnetic timing valve 106 is opened again, the sampling cup 203 can continue to sample. In this way, the plurality of sampling cups 203 can be sampled in turn. When all the sampling cups 203 have completed sampling, the alarm gives an alarm to remind the staff. Before this, the staff can carry out other work, so that the staff do not need to pay attention to the sampling time all the time, and the staff burden can be reduced to a certain extent.

[0059] If the turbidity value of the filtrate is higher than the monitoring value, the control box controls the first electromagnetic valve 107 to close and the second electromagnetic valve 210 to open, so that the filtrate in the outlet main pipe 103 enters the temporary storage cavity 208 through the connecting pipe 209. At the same time, the submersible pump 211 is controlled to operate, and the submersible pump 211 draws the filtrate in the temporary storage cavity 208 through the liquid suction pipe and then conveys the filtrate to the inlet pipe 101 through the return pipe 212, so as to re-filter the filtrate with a higher turbidity. At this stage, the sampling mechanism 2 does not perform sampling work.
