Description

Technical Field

[0001] This invention relates to the field of filter cloth monitoring technology, and more specifically, to a filter cloth monitoring and intelligent control device and control method for the filter pressing process. Background Technology

[0002] Quick-opening filter presses are highly efficient intermittent solid-liquid separation devices widely used in environmental protection, chemical, pharmaceutical, food, and mining industries. Taking the mining industry as an example, filter presses are used to dewater various concentrates. For instance, after filtration by a plate and frame filter press, the moisture content of coal concentrate can be reduced to below 10%, facilitating subsequent transportation. In tailings treatment, filter presses are used to efficiently dewater tailings slurry, achieving dry tailings discharge.

[0003] The morphology and moisture content of the filter cake in the filter chamber depend on the working condition of the filter cloth. Therefore, it is necessary to monitor and maintain the performance of the filter cloth. Existing filter cake monitoring technology is based on traditional plate and frame filter presses and detects the filter cake residue on the filter cloth of a single filter chamber. Traditional plate and frame filter presses rely on a trolley to repeatedly move back and forth to unload different filter chambers sequentially. Quick-opening plate and frame filter presses use hydraulic cylinders to sequentially open all filter plates, completing the discharge of filter cake in one go. Existing technology cannot meet the working requirements of quick-opening plate and frame filter presses. Secondly, existing filter cake residue detection technology for quick-opening plate and frame filter presses only achieves monitoring of the early filtration process and does not identify or predict the state of the filter cloth after filtration, failing to achieve full-cycle monitoring of the filter cloth and affecting the reliability of the filter press operation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a filter cloth monitoring and intelligent control device and control method for the filter pressing process.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A filter cloth monitoring and intelligent control device for the filter pressing process includes a camera, a light source, a PLC control system, a computer control system, and a camera follow-up device. The camera and the light source are both mounted on the camera follow-up device. The camera follow-up device includes a support, a secondary rocker arm, and a primary rocker arm. The surface of the support is rotatably connected to the surface of the secondary rocker arm, and one side of the secondary rocker arm is rotatably connected to the surface of the primary rocker arm. A filter press body is mounted on one side of the camera follow-up device. The filter press body includes a filter plate and a filtrate collection pipe. A discharge platform is mounted on one side of the camera follow-up device, and a bottom plate opening and closing push rod is mounted on one side of the discharge platform. The side of the primary rocker arm away from the secondary rocker arm is rotatably connected to the bottom plate opening and closing push rod.

[0007] The invention is further configured such that: a groove is provided on the secondary rocker arm, and two hanging trunnions are provided inside the groove on the secondary rocker arm. One end of each of the two hanging trunnions is provided with a hanging lug, and a hanging seat is provided on the hanging lug. The camera and the light source are respectively mounted on the two hanging seats by bolts.

[0008] The present invention is further configured such that: an alarm indicator light is provided on the unloading platform, the alarm indicator light is electrically connected to the PLC control system, and the PLC control system is electrically connected to the computer control system.

[0009] A method for monitoring filter cloth and controlling the filter press process includes the following specific operating steps:

[0010] S1. Operating parameter settings: feeding time, pressure, pressing time, pressing time, etc.

[0011] S2. Before the slurry and other materials to be pressed are fed, the bottom plate of the filter press is closed. The camera follow-up device moves under the linkage of the bottom plate opening and closing cylinder, automatically adjusting the camera position and taking pictures of the filtrate collection pipe.

[0012] S3. The filter press operates automatically according to the preset operating parameters. After the feeding is completed, it starts to pressurize and filter the slurry in the filter chamber according to the set pressure value. At this time, the filtrate clarity monitoring algorithm is activated, and various parameters of the camera are automatically set to monitor the filtrate clarity in the collection pipe in real time. The filtrate turbidity is predicted according to the visual algorithm.

[0013] S4. After pressurizing for a certain period of time, take a certain moment as the initial time for monitoring the change in clarity, let's say it's t0. Then, extract the predicted turbidity (Z) of the filtrate at intervals of T to obtain Z. t0 Z t0+T Z t0+2T ...Z t0+nT There are n+1 sets of data. The turbidity of the filtrate at different times is compared. If the turbidity of the filtrate decreases, the filter cloth is working normally. Otherwise, the filter cloth is judged to be damaged and it is suggested to replace the filter cloth.

[0014] S5. The camera monitors the filtrate discharge from the manifold in real time, detecting filtrate droplets and columns. Combining target detection algorithms and time-series analysis, it monitors the filtrate discharge status from the manifold, predicts whether the filtrate has been completely discharged, and records the time t when the filtrate discharge from the manifold is complete. p ;

[0015] S6. After the filter press is finished, the filter press performs the cake unloading operation. The bottom plate opens, the camera follow-up device is linked, and the camera moves to the filter cake monitoring position. The camera detection target is changed to the filter cake. The filter cake discharge monitoring subsystem is started. The filter plate opens to unload the cake. The high-speed camera detects the filter cake falling in sequence and judges the filter cake discharge status of each filter chamber.

[0016] S7. The camera monitors the filter cakes that are discharged in sequence in real time. Combined with the target detection algorithm and time series analysis, the discharge status of filter cakes in all filter chambers is monitored. The value is calculated based on the surface area of ​​the discharged filter cakes to predict whether the filter cakes in the filter chambers are completely discharged. The filter cakes are classified into two categories: whether the filter cakes are completely discharged and the filter chamber number Li in which the filter cakes are not completely discharged is recorded.

[0017] S8, Optimization control method for operating parameters such as pressurization time, pressure, and number of whole machine cleaning cycles: The input module receives feedback signals from the computer control system, the output module controls the alarm indicator, and the human-machine interface sets the operating parameters, including but not limited to pressurization time, pressurization pressure, vibration unloading, and whole machine cleaning.

[0018] The present invention is further configured as follows: the binary classification result in S6 is that the filter cake is completely discharged and the filter cake is not completely discharged. The filter chamber number Li where the filter cake is not completely discharged is recorded. After the cake is unloaded, the number of filter chambers with incomplete filter cake discharge Lw is calculated. The computer control system transmits the number information Li to the PLC controller. The PLC controls the corresponding filter chamber alarm indicator to turn on, prompting the worker that the filter cake in that filter chamber is not completely discharged.

[0019] The present invention is further configured as follows: if Lw≤5 in S6, the worker is prompted to remove the residual filter cake in the filter chamber according to the position of the alarm indicator (4); if 5<Lw≤15, the worker is prompted to remove the residual filter cake in the filter chamber manually, perform vibration unloading and whole machine cleaning according to the position of the alarm indicator (4); if Lw>15, a fault is indicated and the machine is stopped for inspection.

[0020] The present invention is further configured such that: in S8, the pressurization time and pressure are preset; after the feeding operation is completed, the intelligent optimization control subsystem starts to work; based on the feedback signals from the filtrate clarity monitoring subsystem, the filtrate discharge monitoring subsystem and the filter cake discharge monitoring subsystem, the intelligent real-time optimization control is performed on the filter press operation parameters (pressurization time, pressure, number of machine cleaning cycles), thereby controlling the various parameters set by the human-machine interface.

[0021] The advantages of this invention are:

[0022] This invention discloses a filter cloth monitoring and intelligent control device and control method for the filter pressing process. The device has a simple structure and is easy to install. The device moves in conjunction with the opening and closing push rod of the discharge bottom plate without the need for external power. The device automatically arranges the camera shooting angle and the light source illumination position as the filter press process progresses, realizing the switching of the monitoring objects (filtrate and filter cake at the collection pipe). The device is equipped with a camera and light source connection structure, and the camera and light source can maintain their posture by their own weight.

[0044] Please see Figure 1-15 The present invention provides the following technical solution: a filter cloth monitoring and intelligent control device for the filter pressing process, including a camera 1, a light source 2, a PLC control system 6, a computer control system 7, and a camera follower device 3. The camera is an industrial camera. Both the camera and the light source 2 are mounted on the camera follower device 3. The camera follower device 3 includes a bracket 30, a secondary rocker arm 31, and a primary rocker arm 35. The surface of the bracket 30 is rotatably connected to the surface of the secondary rocker arm 31. One side of the secondary rocker arm 31 is rotatably connected to the surface of the primary rocker arm 35. A filter press body 5 is provided on one side of the camera follower device 3.

The side of the primary rocker arm 35 away from the secondary rocker arm 31 is rotatably connected to the bottom plate opening and closing push rod 53.

[0045] The secondary rocker arm 31 has a groove, and two hanging trunnions 34 are provided inside the groove. One end of each hanging trunnion 34 is provided with a hanging ear 32, and a hanging seat 33 is provided on the hanging ear 32.

[0047] Specifically, camera 1 and light source 2 are mounted on mounting base 33. Mounting base 33 has bolt holes on all four sides, allowing camera 1 to be mounted from the side or back depending on site requirements. Mounting base 33 is fixed to the keyway of mounting lug 32 with bolts, allowing adjustment of its vertical position via the keyway. Mount lug 32 is connected to the secondary rocker arm 31 via mounting lug shaft 34, a stepped shaft with threads at the end.

[0049] A method for monitoring filter cloth and controlling the filter press process includes the following specific operating steps:

[0050] S1. Operating parameter settings: feeding time, pressure, pressing time, pressing time, etc.

[0051] S2. Before the slurry and other materials to be pressed are fed, the bottom plate of the filter press is closed. The camera follow-up device moves under the linkage of the bottom plate opening and closing cylinder, automatically adjusting the camera position and taking pictures of the filtrate collection pipe.

[0052] S3. The filter press operates automatically according to the preset operating parameters. After the feeding is completed, it starts to pressurize and filter the slurry in the filter chamber according to the set pressure value. At this time, the filtrate clarity monitoring algorithm is activated, and various parameters of the camera are automatically set to monitor the filtrate clarity in the collection pipe in real time. The filtrate turbidity is predicted according to the visual algorithm.

[0053] S4. After pressurizing for a certain period of time, take a certain moment as the initial time for monitoring the change in clarity, let's say it's t0. Then, extract the predicted turbidity (Z) of the filtrate at intervals of T to obtain Z. t0 Z t0+T Z t0+2T ...Z t0+nT There are n+1 sets of data. The turbidity of the filtrate at different times is compared. If the turbidity of the filtrate decreases, the filter cloth is working normally. Otherwise, the filter cloth is judged to be damaged and it is suggested to replace the filter cloth.

[0054] S5. The camera monitors the filtrate discharge from the manifold in real time, detecting filtrate droplets and columns. Combining target detection algorithms and time-series analysis, it monitors the filtrate discharge status from the manifold, predicts whether the filtrate has been completely discharged, and records the time t when the filtrate discharge from the manifold is complete. p ;

[0055] By monitoring the clarity of the filtrate and the filtrate discharge in real time, the condition of the filter cloth and the status of filtrate discharge can be determined.

[0056] S6. After the filter press is finished, the filter press performs the cake unloading operation. The bottom plate opens, the camera follow-up device is linked, and the camera moves to the filter cake monitoring position. The camera detection target is changed to the filter cake. The filter cake discharge monitoring subsystem is started. The filter plate opens to unload the cake. The high-speed camera detects the filter cake falling in sequence and judges the filter cake discharge status of each filter chamber.

[0057] Specifically, the binary classification results are complete filter cake discharge and incomplete filter cake discharge. The filter chamber number Li where the incompletely discharged filter cake is located is recorded. After the cake is unloaded, the number Lw of filter chambers where the filter cake is incompletely discharged is calculated. The computer control system 7 transmits the number information Li to the PLC controller. The PLC controls the corresponding filter chamber alarm indicator to turn on, prompting the worker that the filter cake in that filter chamber is incompletely discharged.

[0058] Furthermore, if Lw≤5, the worker is prompted to remove the residual filter cake in the filter chamber according to the position of the alarm indicator (4); if 5<Lw≤15, the worker is prompted to remove the residual filter cake in the filter chamber manually, perform vibration unloading and whole machine cleaning according to the position of the alarm indicator (4); if Lw>15, a fault is indicated and the machine is stopped for inspection.

[0059] S7. The camera monitors the filter cakes that are discharged in sequence in real time. Combined with the target detection algorithm and time series analysis, the discharge status of filter cakes in all filter chambers is monitored. The value is calculated based on the surface area of ​​the discharged filter cakes to predict whether the filter cakes in the filter chambers are completely discharged. The classification is divided into whether the filter cakes are completely discharged and the filter chamber number Li where the filter cakes are not completely discharged is recorded.

[0060] S8, Optimization control method for operating parameters such as pressurization time, pressure, and number of whole machine cleaning cycles: The input module receives feedback signals from the computer control system, the output module controls the alarm indicator 4, and the human-machine interface sets the operating parameters, including but not limited to pressurization time, pressurization pressure, vibration unloading, and whole machine cleaning.

[0061] Furthermore, the pressurization time and pressure are preset. After the feeding operation is completed, the intelligent optimization control subsystem starts to work. Based on the feedback signals from the filtrate clarity monitoring subsystem, filtrate discharge monitoring subsystem, and filter cake discharge monitoring subsystem, the intelligent real-time optimization control of the filter press operation parameters (pressurization time, pressure, number of machine cleaning cycles) is performed, thereby controlling the various parameters set by the human-machine interface.

[0062] By detecting filter cloth damage defects, the filtrate discharge monitoring subsystem monitors the filtrate morphology in the manifold during the pressure filtration process, predicts the completion of filtrate discharge, and records the moment when filtrate discharge is complete. The filter cake discharge monitoring subsystem monitors and predicts the filter cake discharge status in different filter chambers and records the filter chamber number that has not been completely discharged. The intelligent optimization control subsystem receives data from the filtrate clarity monitoring subsystem, the filtrate discharge monitoring subsystem, and the filter cake discharge monitoring subsystem, and performs intelligent optimization control on the pressure filtration process.
