Description

[0002] Sludge treatment is a process of reducing, stabilizing and harmless treatment of sludge. Dewatering is the core link of sludge treatment. The moisture content of sludge is usually as high as 95%-99%, and the volume of sludge will be greatly reduced after dewatering, which can significantly reduce the transportation and disposal cost.

[0003] The Chinese invention patent with publication number CN113716830B discloses a single filter cloth deep sludge dewatering equipment and its working method. The patent increases an ultrasonic vibration mechanism on the tank body of the sludge conditioning tank, uses the action of ultrasonic waves to destroy part of the sludge flocculation, accelerates the dissolution of soluble pollutants, and the coagulation of flocculants, thereby improving the dewatering rate of the filter press.

[0004] The Chinese invention patent with publication number CN118005251B discloses a belt type sludge filter press device and filter pressing method. The patent can complete the synchronous adjustment work of multiple tensioning assemblies at the same time through the operation of the synchronous driving mechanism, without the need for multiple operations of the tensioning assembly.

[0005] The belt filter press is widely used in sludge deep dewatering due to its high continuous operation efficiency. It clamps sludge through two tensioned filter cloths, and realizes solid-liquid separation under the action of roller extrusion and shearing. If the sludge contains hard particles such as sand, metal scraps and glass slag, these hard particles will repeatedly rub the surface of the filter cloth when the filter cloth moves with the roller. The edges and corners of the particles may directly scratch the filter cloth fibers. Especially in the high pressure area (such as the pressing roller), the scratches will quickly expand into cracks. As a key component of the belt filter press, once the filter cloth has cracks, it will cause solid leakage, dewatering efficiency reduction and other adverse consequences. In the existing technology, the filter cloth state monitoring mainly relies on manual inspection, which has serious lag and cannot timely discover the damage of the filter cloth. Therefore, we propose a sludge deep dewatering device and system. SUMMARY

[0038] The three embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0039] First embodiment:

[0040] Figures 1-4 A sludge deep dewatering device is shown, which comprises a belt filter press provided with two circulating and rolling filter cloths 001, and each filter cloth 001 is provided with a cleaning mechanism, and further comprises two filter cloth monitoring mechanisms respectively arranged on the two filter cloths 001, the filter cloth monitoring mechanism comprises an upper monitoring box 201 and a lower monitoring box 202 matched with the filter cloth 001, the upper monitoring box 201 and the lower monitoring box 202 are symmetrically arranged above and below the filter cloth 001, and the upper monitoring box 201 and the lower monitoring box 202 are slidably attached to the filter cloth 001, the bottom end of the upper monitoring box 201 and the top end of the lower monitoring box 202 are both arranged in an open shape, the upper monitoring box 201 is fixedly installed with a monitoring light 204, the lower monitoring box 202 is provided with a plurality of brightness sensors 205 distributed in a rectangular array, the top end of the upper monitoring box 201 is communicated with an air charging pipe 206, one end of the air charging pipe 206 away from the upper monitoring box 201 is connected with an air pump 207, and the outer wall of the lower monitoring box 202 is communicated with an air exhaust pipe 208.

[0041] As a further improvement of the present application, the filter cloth monitoring mechanism further comprises two connecting frames 203 for connecting the upper monitoring box 201 and the lower monitoring box 202, the connecting frame 203 is arranged in a C shape, the two ends of the connecting frame 203 are fixedly connected with the upper monitoring box 201 and the lower monitoring box 202 respectively, and the two connecting frames 203 are respectively located on the left and right sides of the upper monitoring box 201, and the connecting frame 203 is fixedly connected with the body of the belt filter press.

[0042] The filter cloth monitoring mechanism further comprises a filter cloth monitoring and warning system, which comprises a monitoring control module, a crack judgment module and an abnormality warning module, the monitoring control module is signal connected with the monitoring light 204, the brightness sensor 205 and the air pump 207, the brightness sensor 205 is signal connected with the crack judgment module, the crack judgment module is signal connected with the abnormality warning module, and the crack judgment module is pre-set with a brightness threshold value.

[0043] When the belt filter is started to dewater the sludge, the monitoring control module starts the monitoring light 204, the brightness sensor 205 and the air pump 207, the brightness sensor 205 is used to monitor the brightness data in real time, and the brightness data monitored by the brightness sensor 205 is transmitted to the crack judgment module in real time, the crack judgment module is used to judge whether there is a crack on the filter cloth 001 by analyzing the brightness data, when the belt filter is running, the filter cloth 001 will slide through the upper monitoring box 201 and the lower monitoring box 202 in a cycle, under normal circumstances, that is, when there is no crack on the filter cloth 001, the light emitted by the monitoring light 204 can only enter the lower monitoring box 202 in a small amount (even difficult), and the brightness data monitored by each brightness sensor 205 is at a low level, but if there is a crack on the filter cloth 001, when the crack passes through the upper monitoring box 201 and the lower monitoring box 202, the light emitted by the monitoring light 204 will enter the lower monitoring box 202 in a large amount through the crack, causing the brightness data monitored by the brightness sensor 205 to increase significantly (the brightness data exceeds the brightness threshold), therefore, the brightness sensor 205 can judge whether there is a crack on the filter cloth 001 by analyzing the brightness data, when the brightness sensor 205 determines that there is a crack on the filter cloth 001, the brightness sensor 205 will control the abnormal alarm module to alarm;

[0044] After the air pump 207 is started, it will continuously fill air into the upper monitoring box 201 through the air pipe 206 at a constant volume flow, so that there is a pressure difference between the upper monitoring box 201 and the lower monitoring box 202, when the crack passes between the upper monitoring box 201 and the lower monitoring box 202, under the action of the pressure difference, the crack will be opened, so that more light can enter the lower monitoring box 202, avoiding the misjudgment caused by the closure of the crack, and greatly improving the accuracy and reliability of the filter cloth 001 state monitoring;

[0045] Therefore, by arranging the filter cloth monitoring mechanism, the filter cloth state is monitored in real time, and when the filter cloth 001 is found to have a crack, an alarm is given, so that the relevant technical personnel can find and timely maintain and process the filter cloth 001, thereby the adverse effects caused by the crack in the filter cloth 001 can be significantly reduced, and during the monitoring, the crack is actively opened by the pressure difference, which greatly improves the accuracy of the monitoring.

[0046] In the forward direction of the filter cloth 001, the filter cloth monitoring mechanism is located downstream of the cleaning mechanism, so that the filter cloth monitoring mechanism monitors the cleaned filter cloth 001, which can improve the accuracy of monitoring and judgment.

[0047] Second embodiment:

[0048] Figures 5-7A sludge deep dewatering device is shown. Unlike the first embodiment, the upper monitoring box 201 is also equipped with an upper air pressure sensor 209, and the lower monitoring box 202 is also equipped with a lower air pressure sensor 210. Both the upper air pressure sensor 209 and the lower air pressure sensor 210 are connected to the crack judgment module. The crack judgment module is also preset with a pressure difference reduction threshold. The crack judgment module is configured to calculate the real-time air pressure difference based on the air pressure data monitored by the upper air pressure sensor 209 and the lower air pressure sensor 210, and to determine whether there are cracks on the filter cloth 001 by analyzing the brightness data monitored by the brightness sensor 205 and the real-time air pressure difference.

[0049] The upper air pressure sensor 209 and the lower air pressure sensor 210 are used to monitor the air pressure in the upper monitoring box 201 and the lower monitoring box 202 in real time, respectively. The air pressure data monitored by the upper air pressure sensor 209 and the lower air pressure sensor 210 are transmitted to the crack judgment module in real time. The crack judgment module calculates the real-time air pressure difference between the upper monitoring box 201 and the lower monitoring box 202 based on the air pressure data. In this embodiment, when the crack judgment module judges whether there is a crack on the filter cloth 001, it also makes a comprehensive judgment based on the real-time air pressure difference. Since when the crack passes between the upper monitoring box 201 and the lower monitoring box 202, the air in the upper monitoring box 201 can flow quickly into the lower monitoring box 202 through the crack, which will also cause the real-time air pressure difference to drop significantly (the real-time air pressure difference is lower than the air pressure difference drop threshold). Therefore, when the brightness data increases significantly and the air pressure difference also drops significantly, the crack judgment module will determine that there is a crack on the filter cloth 001, which can effectively prevent false judgment.

[0050] Therefore, by combining the upper air pressure sensor 209 and the lower air pressure sensor 210, the crack detection module can make a comprehensive judgment based on both brightness and air pressure difference when determining whether there is a crack on the filter cloth 001. This can effectively avoid misjudgment and further improve the accuracy of monitoring.

[0051] The intelligent alarm monitoring system also includes a blockage judgment module. The upper air pressure sensor 209 and the lower air pressure sensor 210 are both connected to the blockage judgment module. The blockage judgment module is also connected to the abnormal alarm module. The blockage judgment module has a preset air pressure difference rise threshold, which is greater than the air pressure difference fall threshold.

[0052] The air pressure data monitored by the upper air pressure sensor 209 and the lower air pressure sensor 210 are also transmitted to the blockage judgment module in real time. The blockage judgment module also calculates the real-time air pressure difference between the upper monitoring box 201 and the lower monitoring box 202 based on the air pressure data, and judges whether there is a blockage in the filter cloth 001 by analyzing the real-time air pressure difference. When the filter cloth 001 is blocked, the airflow will be affected when the blockage passes through the upper monitoring box 201 and the lower monitoring box 202, causing the real-time air pressure difference to increase significantly (the real-time air pressure difference exceeds the air pressure difference rise threshold). Therefore, the blockage judgment module can judge whether there is a blockage in the filter cloth 001 by analyzing the real-time air pressure difference. When the blockage judgment module determines that the filter cloth 001 is blocked, the blockage judgment module will control the abnormal alarm module to issue an alarm.

[0053] Therefore, by combining the blockage detection module and other components, the filter cloth monitoring mechanism can also monitor whether there is a blockage in the filter cloth 001, and will also issue an alarm when a blockage is detected in the filter cloth 001, prompting relevant technicians to take timely action. This not only improves the intelligence and functionality of the filter cloth monitoring mechanism, but also further improves the effect and efficiency of sludge dewatering.

[0054] The third implementation method:

[0055] Figure 8 A sludge deep dewatering system is shown, comprising:

[0056] Sludge deep dewatering device;

[0057] Sludge conditioning equipment is used to add chemical conditioning agents to sludge;

[0058] The feed pump is used to feed the sludge, after it has been conditioned by the sludge conditioning device, into the belt filter press.

[0059] A sludge cake conveyor is installed at the discharge end of a belt filter press and is used to transport sludge cakes.

[0060] The central control unit is connected to the sludge conditioning unit, belt filter press, feed pump, and sludge cake conveyor via signal connections.

[0061] The management and control unit has a preset delay duration;

[0062] The crack detection module is connected to the management control unit. When the crack detection module determines that there is a crack on the filter cloth 001, the management control unit controls the sludge conditioning device, feed pump and belt filter press to stop immediately. It also controls the cake conveyor to stop after a delay. Immediately stopping the belt filter press can avoid the risks of continuous sludge leakage and aggravated filter cloth tearing. Immediately stopping the feed pump can prevent the belt filter press inlet from being blocked. Immediately stopping the sludge conditioning device can prevent the ineffective consumption of chemicals. The delayed stopping of the cake conveyor is to empty the formed cake.

[0063] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
