The flow detection mechanism 600, the circulating pump 700 and the second control valve 920 on the second slurry pipe 400 are sequentially distributed, and the flow detection mechanism 600 and the circulating pump 700 are close to the second slurry tank 200, and the second control valve 920 is close to the filtering mechanism 800. It is understood that the positions of the flow rate detection mechanism 600 and the circulation pump 700 may be changed.
Preferably, the flow sensing mechanism 600 is a flow meter.
Further, the first vat 100 is disposed at a lower height than the second vat 200.
Preferably, as shown in fig. 1, the first vat 100 is integrally connected with the second vat 200. The second slurry tank 200 is arranged above the first slurry tank 100 to form a height difference, and slurry in the second slurry tank 200 can overflow into the first slurry tank 100 under the action of the height difference. The slurry containing impurities flows from the first slurry tank 100 into the filtering mechanism 800, is purified, and then flows into the second slurry tank 200, thus completing the circulation purification of the slurry. It is understood that in other embodiments, the second vat 200, the filtering mechanism 800 and the first vat 100 may be separately arranged from top to bottom, the slurry containing impurities in the first vat 100 flows into the filtering mechanism 800 under the gravity, and flows into the first vat 100 after being purified, and the slurry used in the first vat 100 may be pumped back to the second vat 200, which is not limited herein.
Further, referring to fig. 1, the filter mechanism 800 includes a filter vat 810 and a filter screen 820. The filter screen 820 is arranged in the filter vat 810 along the axial direction and separates the inner cavity of the filter vat 810 to form a first filter cavity and a second filter cavity, the first pulp pipe 300 is communicated with the first filter cavity, and the second pulp pipe 400 is communicated with the second filter cavity. The aperture of the filter screen 820 is 100-200 meshes.
It will be understood that the filter screen 820 can be rolled to form a first filter cavity, and the filter screen 820 and the inner wall of the filter vat 810 surround to form a second filter cavity, specifically, the filter screen 820 is a cylindrical filter screen 820 and is axially disposed in the filter vat 810. It is understood that in other embodiments, the shape of the filter vat 810 may also be other shapes such as a rectangular parallelepiped, and the filter screen 820 may also be a circular filter screen 820, a square filter screen 820, or a rectangular filter screen 820 disposed in the filter vat 810, which is not limited herein.
Further, the filter screen 820 is detachably connected to the filter barrel 810, and when the filter mechanism 800 is cleaned, only the filter screen 820 needs to be lifted out to clean the impurities remained in the filter mechanism.
Further, the filtering barrel 810 is provided with a liquid inlet communicated with the filtering cavity and a liquid outlet communicated with the second filtering cavity. The first slurry pipe 300 is communicated with the liquid inlet, and the second slurry pipe 400 is communicated with the liquid outlet.
Further, the control mechanism further comprises a controller (not shown). The controller is electrically connected to the flow rate detection mechanism 600, the first control valve 910, the second control valve 920, and the third control valve 930. The controller is configured to open the filtering mechanism 800 when the flow rate detecting mechanism 600 monitors that the actual flow rate of the slurry in the second slurry pipe 400 is within the preset flow rate range, and close the filtering mechanism 800 when the flow rate detecting mechanism 600 monitors that the actual flow rate of the slurry in the second slurry pipe 400 is lower than the lower limit value of the preset flow rate range.
If the filtering mechanism 800 is in an abnormal condition, for example, the filtering mechanism is blocked by impurities in the slurry after a period of operation, the circulation of the slurry is blocked, so that the purified slurry cannot be recirculated to the second slurry tank 200, and the actual flow rate of the slurry in the second slurry pipe 400 is lower than the preset range during normal operation because the slurry cannot flow out. When the flow rate detection mechanism 600 detects that the liquid level in the second slurry pipe 400 is within the preset range, which indicates that the filtering mechanism 800 is working normally, the controller keeps the first control valve 910, the second control valve 920, the circulating pump 700 and the flow rate detection mechanism 600 open, and the second control valve 920 is closed at the same time; when the actual flow of the slurry in the second slurry pipe 400 is lower than the lower limit value of the preset flow range, the first control valve 910 and the second control valve 920 are closed, and the second control valve 920 is opened at the same time, so that accidents are prevented.
Further, the slurry filtering device 10 also includes an alarm mechanism. The alarm mechanism is electrically connected with the flow detection mechanism 600, and works when the actual flow detected by the flow detection mechanism 600 is smaller than the minimum value of the preset flow range. When the filtering mechanism 800 is blocked and the flow rate of the slurry in the second slurry pipe 400 is lower than the lower limit value of the preset range, the alarm mechanism is turned on to prompt an operator that the filtering mechanism 800 is abnormal and needs to be cleaned. In this embodiment, the alarm mechanism is an alarm lamp, and it should be understood that in other embodiments, the alarm mechanism may be an audible alarm or the like, which is not limited herein.
Further, the slurry filtering device 10 further comprises a cleaning protection switch, the cleaning protection switch comprises a cleaning protection mode and a filtering mode, when the actual flow rate of the slurry in the second slurry pipe 400 is lower than the lower limit value of the preset flow rate range, the filtering mechanism 800 is blocked and needs to be cleaned, and before cleaning, the cleaning protection switch is switched to the cleaning protection mode to ensure that the filtering mechanism 800 is closed, so that the slurry is prevented from being sprayed out to damage cleaning personnel; after the filtering mechanism 800 is cleaned, the cleaning protection switch is switched to the filtering mode, and the filtering mechanism 800 can normally purify the slurry.
In this embodiment, the cleaning protection mode and the filtering mode of the cleaning protection switch are manually switched by an operator according to the state of the alarm mechanism, when the alarm mechanism is not turned on, the cleaning protection switch is in the filtering mode, and the slurry filtering device 10 normally works; after the alarm mechanism is turned on, an operator finds that the alarm mechanism is turned on, switches the cleaning protection switch to the cleaning protection mode, ensures that the filter mechanism 800 is turned off, takes out the filter screen 820 and starts to clean the filter vat 810 of the residual impurities therein, after the cleaning is finished, puts back the filter screen 820, turns off the filter vat 810, and switches the cleaning protection switch to the filter mode.
The embodiment also provides a slurry filtering method, which comprises the following steps:
referring to fig. 1 and 2, the controller opens the first control valve 910, the second control valve 920, the circulation pump 700 and the flow rate detection mechanism 600, closes the third control valve 930, the first vat 100 and the second vat 200 perform circular filtration of the slurry through the filtration mechanism 800, the controller controls the flow rate detection mechanism 600 to detect the actual flow rate of the slurry in the second slurry pipe 400, when the actual flow rate is within a preset flow rate range, the slurry filtration is normal, and when the actual flow rate is smaller than the minimum value of the preset flow rate range, the filtration mechanism 800 is blocked, at this time, the controller controls the first control valve 910 and the second control valve 920 to be closed, and the controller controls the circulation pump 700, the flow rate detection mechanism 600 and the third control valve 930 to be opened. After the controller closes the filtering mechanism 800, an operator opens the filtering mechanism 800 to clean the residual impurities therein according to the reminding of the alarm mechanism, and the slurry can be continuously purified after the filtering net 820 returns to the original position after the cleaning is finished.
