Description

TECHNICAL FIELD

[0001] The present application relates to the field of building material processing equipment, and in particular to a building surplus material recycling method, system, storage medium and intelligent terminal. BACKGROUND

[0002] Materials used in buildings are collectively referred to as building materials, which can be divided into structural materials, decorative materials and some special materials. Structural materials include wood, bamboo, stone, cement, concrete, metal, bricks, ceramics, glass, engineering plastics and composite materials, etc. Decorative materials include various paints, varnishes, plating, veneer, various ceramic tiles and glass with special effects, etc. Special materials refer to materials used for waterproofing, moisture-proofing, corrosion-proofing, fire-proofing, flame-retardant, sound-proofing, heat-proofing, heat-insulating and sealing. The leftover materials in construction engineering are called building surplus materials.

[0003] In related technologies, a building surplus material classification and recycling device is disclosed in Chinese Patent No. CN206654418U, which includes a mounting foot, a mounting base fixedly installed on the top of the mounting foot, a small particle filter screen fixedly installed on the top of the inner cavity of the mounting base, an activated carbon filter layer fixedly installed on the bottom of the small particle filter screen and located in the inner cavity of the mounting base, a water storage tank fixedly installed on the bottom of the activated carbon filter layer and located in the inner cavity of the mounting base, a water outlet pipe communicated with the bottom of the water storage tank and penetrating through the bottom of the mounting base, a box body fixedly installed on the top of the mounting base, a water receiving tray fixedly installed on the bottom of the inner cavity of the box body, and a sliding rail fixedly installed on the inner cavity of the box body above the water receiving tray. The building surplus material classification and recycling device can effectively ensure that the waste materials are classified into three different sizes, facilitate the separation and recycling of building surplus materials of different sizes, and effectively increase the recycling efficiency.

[0004] In the prior art, although three filter slides are provided for classification, when large particles or even plate materials close the mesh holes above the remaining small particle materials, the separation is still incomplete, and small particles are taken out together with plate materials, resulting in low classification efficiency, which still has room for improvement. SUMMARY

[0005] In order to improve the problem that when large particles or even plate materials close the mesh holes above the remaining small particle materials, the separation is still incomplete, and small particles are taken out together with plate materials, resulting in low classification efficiency, the present application provides a building surplus material recycling method, system, storage medium and intelligent terminal.

[0006] In a first aspect, the present application provides a building surplus material recycling method, which adopts the following technical solution:

[0007] A building surplus material recycling method, comprising:

[0008] When the excess material enters the recycling device for shaking, the filter screen number and the preliminary filter screen weight are obtained;

[0009] When the preliminary filter screen weight no longer changes, the cover plate of the filter screen corresponding to the filter screen number is closed, the filter screen is arranged in a box shape, an opening for feeding is arranged above the filter screen, a cover plate controlled by a gas cylinder and covering the opening of the filter screen is arranged on the side wall of the filter screen close to the opening, a filter screen hole of the same grade as the filter screen is arranged on the cover plate, and rotating shafts driven by motors and arranged horizontally are arranged on both sides of the filter screen;

[0010] After the filter screen corresponding to the filter screen number and the cover plate are rotated around the rotating shafts, the preliminary filter screen weight is obtained again by shaking, and the preliminary filter screen weight is defined as the rotating filter screen weight;

[0011] When the rotating filter screen weight and the preliminary filter screen weight are different, the rotating filter screen weight before being rotated again is updated as the preliminary filter screen weight, and the original preliminary filter screen weight is removed;

[0012] When the rotating filter screen weight and the preliminary filter screen weight are the same, the rotating number of turns is started to be accumulated;

[0013] When the rotating filter screen weight and the preliminary filter screen weight are different again, the rotating number of turns is reset to zero and is not accumulated again until the rotating filter screen weight and the preliminary filter screen weight are the same again;

[0014] When the rotating number of turns is greater than a preset critical number of times, the filter screen corresponding to the filter screen number is pulled out of the material outlet through a pulling device.

[0015] By adopting the above technical scheme, the filter screen is rotated, so that small particle impurities originally above can fall under the action of gravity and will not be blocked by large particle or plate-shaped materials, and the efficiency of the excess material layering recovery is improved.

[0016] Optionally, the method further includes filter screen cleaning before the excess material enters the recycling device, and the method includes:

[0017] The corresponding filter screen number is defined as a rotating filter screen number;

[0018] According to the rotating filter screen number, a corresponding rotating dredging device number is found from a preset device database, the box body is provided with a dredging device, the dredging device is slidably connected to the box body and is provided with a dredging moving needle below, so as to dredge the filter screen;

[0019] Before the excess material enters the recycling device, the preliminary filter screen weight corresponding to the rotating filter screen number is obtained, and the preliminary filter screen weight is defined as a preliminary pure screen weight.

[0020] moving the corresponding dredging device into the box body and dredging the filter screen corresponding to the corresponding rotating filter screen number to obtain the dredging moving distance and re-obtain the preliminary pure screen weight, and defining the preliminary pure screen weight as the dredging pure screen weight;

[0021] outputting a filter screen blockage information when the dredging moving distance is less than the preset dredging critical distance;

[0022] continuing to dredge the filter screen corresponding to the corresponding rotating filter screen number when the dredging moving distance is equal to the dredging critical distance and the dredging pure screen weight is different from the preliminary pure screen weight until the dredging pure screen weight is the same as the preliminary pure screen weight.

[0023] By using the above technical solution, the filter screen is dredged by using the corresponding dredging moving needle, so that the mesh of the filter screen is always kept unobstructed before use, and the small particle excess material will not fall into the lower layer, thereby improving the service life of the filter screen.

[0024] Optionally, the method for rotating the filter screen corresponding to the filter screen number and the cover plate around the rotating shaft comprises:

[0025] finding the corresponding camera number from the equipment database according to the rotating filter screen number;

[0026] photographing the filter screen corresponding to the rotating filter screen number by the camera corresponding to the camera number to obtain a blocked area;

[0027] analyzing the blocked mesh number based on the blocked area, the rotating filter screen number and the preset mesh number;

[0028] finding the corresponding test dredging device number and test dredging moving needle number from the preset association database according to the blocked mesh number and the rotating filter screen number;

[0029] moving the corresponding dredging device into the box body and moving the dredging moving needle corresponding to the test dredging moving needle number to the position corresponding to the blocked mesh number in the filter screen corresponding to the corresponding rotating filter screen number in turn and obtaining the feedback force and the dredging distance;

[0030] continuing to move downward when the feedback force is less than the preset breaking critical force and the dredging distance is less than the dredging critical distance;

[0031] replacing the dredging moving needle corresponding to the new test dredging moving needle number to move to the position corresponding to the blocked mesh number in the filter screen corresponding to the corresponding rotating filter screen number when the feedback force is less than the breaking critical force and the dredging distance is equal to the dredging critical distance;

[0032] When the feedback force at any one of the blocking mesh hole numbers is less than the breaking critical force and the unblocking distance is equal to the unblocking critical distance, no rotation is performed;

[0033] When the feedback force at any one of the blocking mesh hole numbers is less than the breaking critical force and the unblocking distance is equal to the unblocking critical distance, no rotation is performed;

[0034] By using the above technical solution, the area blocked by the large particles is analyzed, and then the corresponding area is unblocked to break some of the residual materials that are originally small particles, so as to prevent the residual materials from falling although they are small particles, and ensure the stability of the residual materials on the corresponding filter screen.

[0035] Optionally, the method of not performing rotation when the feedback force at any one of the blocking mesh hole numbers is less than the breaking critical force and the unblocking distance is equal to the unblocking critical distance includes:

[0036] Based on the blocking area and the blocking mesh hole number, the peripheral blocking mesh hole number is determined, and the test unblocking moving needle number corresponding to the peripheral blocking mesh hole number is defined as the peripheral test unblocking moving needle number;

[0037] Based on the blocking area and the peripheral blocking mesh hole number, the dialing direction is determined;

[0038] When the unblocking moving needle corresponding to the peripheral test unblocking moving needle number is inserted to the preset dialing distance at any one of the peripheral blocking mesh hole numbers, dialing is performed in the dialing direction;

[0039] After all the peripheral test unblocking moving needle numbers are dialed, the blocking area is reacquired based on the peripheral test unblocking moving needle number, and the peripheral test unblocking moving needle number is updated until there is no blocking area or dialing cannot be performed.

[0040] By using the above technical solution, when the unblocking moving needle can be inserted, it means that the two can be separated at this time, and then the entire blocking area is completely separated by dialing, and the residual materials that are originally small particles are displayed in the original state, thereby improving the efficiency of dialing and separating the dialing rod from the blocking area.

[0041] Optionally, the method of performing dialing in the dialing direction when the unblocking moving needle corresponding to the peripheral test unblocking moving needle number is inserted to the preset dialing distance at any one of the peripheral blocking mesh hole numbers includes:

[0042] Any two adjacent peripheral test unblocking moving needle numbers are selected, and the dialing angle difference is calculated according to the respective dialing directions, and the selected adjacent peripheral test unblocking moving needle numbers are defined as selected unblocking moving needle numbers;

[0043] Form a plurality of peripheral test dredging mobile needle number groups based on the dialing angle difference, the peripheral test dredging mobile needle number groups include peripheral test dredging mobile needle numbers adjacent in turn at the head and tail, and the dialing angle difference formed by any two corresponding dialing directions of the peripheral test dredging mobile needle numbers in the same peripheral test dredging mobile needle number group is less than the preset influence critical angle;

[0044] Determine the moderate dialing direction according to the dialing direction corresponding to the peripheral test dredging mobile needle numbers in the same peripheral test dredging mobile needle number group, and the sum of the angle difference values between the moderate dialing direction and any one dialing direction is the minimum;

[0045] When the peripheral test dredging mobile needle numbers in the same peripheral test dredging mobile needle number group are inserted into the dredging critical distance, the moderate dialing direction is dialed.

[0046] By adopting the above technical scheme, by moving a plurality of dredging mobile needles in the same direction, the dredging device only needs to move in several directions, without the need to move in each dialing direction, thereby reducing the moving track of the dredging device and improving the dredging efficiency.

[0047] Optionally, the further method of rotating the filter screen corresponding to the filter screen number and the cover plate around the rotation axis comprises:

[0048] Determine the closest filter screen edge line based on the plugging area, the preset horizontal filter screen area and the rotation axis of the rotation axis, and define the filter screen edge line as the impact filter screen edge line;

[0049] Determine the rotation direction based on the impact filter screen edge line;

[0050] Rotate the filter screen corresponding to the filter screen number and the cover plate around the rotation axis according to the rotation direction and the preset initial rotation speed, and obtain the rotation angle and the self-shaking information;

[0051] When the amplitude and frequency corresponding to the self-shaking information are less than the amplitude and frequency corresponding to the preset critical impact information, continue to rotate and continuously obtain the rotation angle and the self-shaking information;

[0052] When the amplitude and frequency corresponding to the self-shaking information are greater than the amplitude and frequency corresponding to the critical impact information, obtain the reduced rotation speed based on the preset reduced speed span and the initial rotation speed;

[0053] After adjusting the initial rotation speed to the reduced rotation speed, continue to rotate and continuously obtain the rotation angle and the self-shaking information;

[0054] continues to rotate and continuously acquires the rotation angle and the self-shaking information after the rotation speed is adjusted to the gentle transition speed when the rotation angle falls within the vertical angle range;

[0055] continues to rotate and continuously acquires the rotation angle and the self-shaking information after the gentle transition speed is adjusted to the reduced rotation speed before falling within the vertical angle range when the rotation angle deviates from the vertical angle range.

[0056] By adopting the above technical solution, when rotating, in order to reduce the impact caused by the turnover of the excess material during the rotation, the shaking information and the rotation angle caused by the turnover are monitored at all times, and when the shaking information is too large or almost vertical, the turnover speed is reduced, which greatly ensures that the turnover process will not cause a large impact on the filter screen, thereby improving the service life of the filter screen.

[0057] Optionally, the method of continuing to rotate after the initial rotation speed is adjusted to the reduced rotation speed comprises:

[0058] When the reduced rotation speed is less than the preset minimum critical speed, the corresponding hold-up cylinder number is found from the equipment database based on the rotating filter screen number;

[0059] The cylinder corresponding to the hold-up cylinder number is driven to move the filter screen corresponding to the rotating filter screen number to close to the cover plate of the corresponding filter screen, and the moving distance and the clamping force are acquired;

[0060] When the clamping force is equal to the preset clamping force, the movement of the filter screen is stopped, and the filter screen corresponding to the filter screen number and the cover plate are rotated around the rotation shaft at the minimum critical speed, and the rotation angle and the self-shaking information are re-acquired;

[0061] When the amplitude and frequency corresponding to the self-shaking information are less than the amplitude and frequency corresponding to the critical impact information, the increased rotation speed is obtained based on the reduced speed span and the minimum critical speed;

[0062] When the amplitude and frequency corresponding to the self-shaking information are equal to the amplitude and frequency corresponding to the critical impact information, the filter screen and the cover plate are rotated at the increased rotation speed until the amplitude and frequency corresponding to the self-shaking information and the amplitude and frequency corresponding to the critical impact information are different.

[0063] By adopting the above technical solution, although the shaking is large and the rotation speed is reduced, when the rotation speed is too small and almost cannot rotate, the amplitude of the shaking is reduced by moving the filter screen and the cover plate close to each other, thereby indirectly increasing the rotation speed.

[0064] In a second aspect, the application provides a construction excess material recycling system, which adopts the following technical solution:

[0065] A construction waste recycling system comprises:

[0066] An acquisition module is configured to acquire the filter screen number, the preliminary filter screen weight, the rotating filter screen weight, the number of rotating circles, the preliminary pure screen weight, the dredged pure screen weight, the rotating angle, the self-shaking information, the moving distance, and the clamping force;

[0067] A memory is configured to store a program of the control method of any of the construction waste recycling methods.

[0068] A processor, and the program in the memory can be loaded and executed by the processor to implement the control method of any of the construction waste recycling methods.

[0069] By rotating the filter screen, the small-particle impurities originally above can fall under the action of gravity without being blocked by large-particle or plate-shaped materials, thereby improving the efficiency of waste layering recycling.

[0070] In a third aspect, the application provides an intelligent terminal, which adopts the following technical solution:

[0071] The intelligent terminal comprises a memory and a processor, and the memory stores a computer program capable of being loaded and executed by the processor to implement any of the construction waste recycling methods.

[0072] By rotating the filter screen, the small-particle impurities originally above can fall under the action of gravity without being blocked by large-particle or plate-shaped materials, thereby improving the efficiency of waste layering recycling.

[0073] In a fourth aspect, the application provides a computer storage medium capable of storing a corresponding program and having a fast processing speed.

[0074] The computer readable storage medium adopts the following technical solution:

[0075] The computer readable storage medium stores a computer program capable of being loaded and executed by the processor to implement any of the construction waste recycling methods.

[0076] By rotating the filter screen, the small-particle impurities originally above can fall under the action of gravity without being blocked by large-particle or plate-shaped materials, thereby improving the efficiency of waste layering recycling.

[0077] In summary, the application has at least the following beneficial technical effects:

[0078] 1. By rotating the filter screen, the small-particle impurities originally above can fall under the action of gravity, thereby improving the efficiency of waste layering recycling.

[0079] 2. The corresponding dredging mobile needle is used to dredge the filter screen, so that the mesh of the filter screen is always kept unobstructed before use, and the excess of small particles does not fall into the lower layer, thereby prolonging the service life of the filter screen.

[0080] 3. The shaking information and the angle of rotation caused by the turning are monitored at all times, and the turning speed is reduced when the shaking information is too large or almost vertical, thereby greatly ensuring that the turning process does not cause a large impact on the filter screen, thereby prolonging the service life of the filter screen.

[0090] In order to make the purpose, technical solutions and advantages of the present application more clear and understandable, the following will be combined with the drawingsFigures 1-9 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0091] This application discloses a method for recycling construction waste. (Refer to...) Figure 1 A method for recycling construction waste includes:

[0092] Step 100: Obtain the filter screen number and preliminary filter screen weight when the remaining material enters the recycling device and is shaken.

[0093] like Figure 2 As shown, the waste material recovery device is equipped with filters of different mesh sizes to separate waste materials of different particle sizes for stratified recovery. The filters are numbered to identify which filter it is, and this number also reveals information such as the selected filter's location, mesh size, and even the mesh sizes of adjacent filters. When waste material enters the recovery device, the waste material on each filter layer is shaken according to standard operation to ensure that as much waste material as possible that can pass through the mesh of that layer flows to the next layer, thus achieving stratified recovery.

[0094] The initial filter weight is the weight of the filter when it is weighed for the first time. Since a rotating shaft is involved in the next step, a weighing sensor can be set on the underside of the rotating shaft so that the rotating shaft rotates on the weighing sensor, and the initial filter weight can be obtained by the weighing sensor.

[0095] Step 101: When the weight of the initial filter screen no longer changes, close the cover plate of the filter screen corresponding to the filter screen number. The filter screen is box-shaped, with a feed opening at the top. The side wall of the filter screen near the opening is equipped with a cover plate controlled by a cylinder to close the opening of the filter screen. The cover plate is equipped with filter screen holes of the same grade as the filter screen. The two sides of the filter screen are equipped with horizontally arranged rotating shafts driven by a motor.

[0096] like Figure 2 As shown, the filter screen is box-shaped to prevent excess material that cannot pass through the mesh from falling from its edges. An opening at the top allows excess material to fall into the filter. To prevent excess material from falling through the opening during the filter's rotation, a closable cover is provided at the opening. However, to allow excess material to fall through the cover after rotation, the cover also has mesh openings of the same size and grade as the filter screen. A motor-driven rotating shaft is used to enable the entire filter screen to rotate.

[0097] Step 102: Continue to shake the filter screen and the cover plate after rotating the filter screen corresponding to the filter screen number around the rotation axis to obtain the preliminary filter screen weight again, and define the preliminary filter screen weight as the rotating filter screen weight.

[0098] The angle of rotation here is 360°, but it will stop for a period of time when it is turned to 180°, and then it is shaken. In addition, if necessary, the shaking process can also be added in the middle process, for example, at 90°, so that the small particles of the remaining material that exist above the large particles or even large pieces of the remaining material but cannot be dropped in the previous shaking process are no longer limited by the large particle remaining material and fall off. Then continue to obtain the purpose of determining whether it has been dropped completely.

[0099] Step 103: When the rotating filter screen weight and the preliminary filter screen weight are different, re-rotate and update the rotating filter screen weight before re-rotation as the preliminary filter screen weight, and remove the original preliminary filter screen weight.

[0100] When the rotating filter screen weight and the preliminary filter screen weight are different, it means that small particles of the remaining material have passed through the filter screen holes and fallen off. At this time, it cannot be determined whether it has been dropped completely, so it is necessary to continue to compare, and the object of comparison is the weight output last time and the weight output this time. Therefore, the rotating filter screen weight before re-rotation is updated as the preliminary filter screen weight, and the original preliminary filter screen weight is removed to update the weight output last time, and the weight output this time can be obtained by measuring after rotation.

[0101] Step 104: When the rotating filter screen weight and the preliminary filter screen weight are the same, start accumulating the number of rotation turns.

[0102] The number of rotation turns is the number of turns of the filter screen. The accumulation can be counted by a counter, that is, the counter automatically increases by one after 360°. When the rotating filter screen weight and the preliminary filter screen weight are the same, it means that the small particle remaining material that can be shaken by turning has been shaken off, but in order to prevent the accidental situation that a part of it is still stuck on the top due to adhesion, the number of rotation turns is accumulated to ensure that it will not continue to be shaken off in the future

[0103] Step 105: When the rotating filter screen weight and the preliminary filter screen weight are different again, reset the number of rotation turns and do not re-accumulate the number of rotation turns until the rotating filter screen weight and the preliminary filter screen weight are the same again.

[0104] When it is different again, it means that it may not have fallen off due to some reason before, so when it is the same again later, the number of rotation turns needs to be re-accumulated.

[0105] Step 106: When the number of rotations exceeds the preset critical number, pull out the filter screen corresponding to the filter screen number through the pulling device.

[0106] The critical number of rotations is a manually set number determined by professionals in the field based on extensive measurement experience and their own common sense. When the number of rotations exceeds the critical number, it is assumed that no small particles remain on the filter screen corresponding to the large particles, and the filter screen can be removed to separate the remaining material into layers.

[0107] Reference Figure 3 It also includes a method for cleaning the filter screen before the residual material enters the recycling device, the method comprising:

[0108] Step 200: Define the corresponding filter screen number as the rotating filter screen number.

[0109] The purpose of this definition is to facilitate filtering.

[0110] Step 201: Find the corresponding rotating cleaning device number from the preset equipment database according to the rotating filter screen number. The box is equipped with a cleaning device, which is slidably connected to the box and has a cleaning moving needle at the bottom to clean the filter screen.

[0111] The rotating unblocking device is numbered according to the unblocking device's number, such as... Figure 2 As shown, a slide rail is provided on one side of the housing, and a cleaning device is mounted on the slide rail. This device consists of multiple telescopic rods that can extend and retract vertically. Here, these telescopic rods are defined as cleaning needles. The size of the cleaning needles is the same as the mesh size of the corresponding filter screen below, and they are aligned with the mesh of the filter screen. When the cleaning needles move downwards, they can enter the mesh to clear any blockages. A database stores a mapping relationship between the rotating filter screen numbers and the rotating cleaning device numbers. These numbers are assigned by those skilled in the art during the installation of the cleaning device and filter screen, and then matched and recorded. When the system receives the corresponding rotating filter screen number, it automatically retrieves the corresponding rotating cleaning device number from the database and outputs it.

[0112] Step 202: Before the residual material enters the recycling device, obtain the weight of the preliminary filter screen corresponding to the rotating filter screen number, and define the weight of the preliminary filter screen as the weight of the preliminary pure screen.

[0113] The initial pure screen weight is the weight of the filter screen in the device before recycling. This weight is obtained in step 100 and will not be described further here.

[0114] Step 203: move the corresponding dredging device into the box body according to the rotation dredging device number, and dredge the corresponding filter screen according to the rotation filter screen number to obtain the dredging moving distance and re-obtain the preliminary pure screen weight, and define the preliminary pure screen weight as the dredging pure screen weight.

[0115] The dredging moving distance is the distance moved by the dredging moving needle. The dredging method is to move the dredging moving needle to the mesh direction of the corresponding filter screen to penetrate the mesh. The dredging pure screen weight is the weight of the filter screen after the impurities in part of the mesh fall to the next layer or directly fall to the bottom.

[0116] Step 204: output the filter screen blockage information when the dredging moving distance is less than the preset dredging critical distance.

[0117] The dredging critical distance is the distance that the dredging moving needle can move downward. Since the length of the dredging moving needle is limited, the distance moved by the dredging moving needle is also limited, so there is a set distance value, but the distance value must ensure that the dredging moving needle can penetrate the mesh of the corresponding filter screen.

[0118] The filter screen blockage information is the information of the filter screen blockage, and the output method can be a more obvious method such as a red light. When it cannot be moved downward, it means that there are impurities on the filter screen to block it, so it cannot be ruled out that the mesh is blocked or there is excess material blocking the movement on the filter screen, but the last time it was pulled out, it will also be cleaned, so it is generally more difficult to handle the excess material, so the possibility of mesh blockage is very large, so the filter screen blockage information is uniformly output.

[0119] Step 205: continue to dredge the corresponding filter screen according to the rotation filter screen number when the dredging moving distance is equal to the dredging critical distance and the dredging pure screen weight and the preliminary pure screen weight are different until the dredging pure screen weight and the preliminary pure screen weight are the same.

[0120] Reference Figure 4 The method for rotating the filter screen corresponding to the filter screen number and the cover plate around the rotation shaft comprises:

[0121] Step 300: find the corresponding camera number from the device database according to the rotation filter screen number.

[0122] The camera number is the number of the camera that can shoot the surface of the filter screen corresponding to the rotation filter screen number. The database stores the mapping relationship between the rotation filter screen number and the camera number, and the database is established in a similar manner to step 201, which will not be repeated here. When the system receives the corresponding rotation filter screen number, it automatically finds the corresponding camera number from the database and outputs it.

[0123] Step 301: The camera corresponding to the camera number is used to take pictures of the filter screen corresponding to the filter screen number to obtain the blocked area.

[0124] The blocked area is an area in the image after shooting that cannot be identified by analyzing the mesh, i.e., the area occupied by the excess material. The blocked area is a different color from the filter screen, i.e., the filter screen is painted a color different from all the excess material, such as purple. The inside of the box can also be painted purple, so only the area that is not purple needs to be analyzed to obtain the blocked area. Here, the blocked area does not need to be very accurate and only needs to be free of falling material. Once the mesh is covered, it will certainly not be captured, so the camera can be moved to the center of the filter screen above, or two symmetrical cameras can be used to capture all areas, or a camera can be used without moving. Once the purple area is not visible, it is the blocked area.

[0125] Step 302: Based on the blocked area, the rotating filter screen number, and the preset mesh number, the blocked mesh number is analyzed and obtained.

[0126] The mesh number is the number of the mesh, which is obtained by manually installing the filter screen and numbering the mesh of the filter screen. The blocked mesh number is the number of the blocked mesh, which is used to determine the corresponding unclogging mobile needle for unclogging. By analyzing the rotating filter screen number, the corresponding filter screen can be obtained, and by analyzing the blocked area and the mesh number, the number of the corresponding blocked mesh can be obtained.

[0127] Step 303: According to the blocked mesh number and the rotating filter screen number, the corresponding test unclogging device number and test unclogging mobile needle number are found in the preset association database.

[0128] The test unclogging device number is the device that can unclog the filter screen corresponding to the rotating filter screen number. The test unclogging mobile needle number is the number of the unclogging mobile needle that can unclog the blocked mesh. The database stores the mapping relationship between the blocked mesh number, the rotating filter screen number, the test unclogging device number, and the test unclogging mobile needle number. The mapping relationship is obtained by personnel in the field after numbering and according to actual conditions. When the system receives the corresponding blocked mesh number and rotating filter screen number, it automatically finds the corresponding test unclogging device number and test unclogging mobile needle number from the database and outputs them.

[0129] Step 304: The unclogging device corresponding to the test unclogging device number is moved into the box, and the unclogging mobile needle corresponding to the test unclogging mobile needle number is moved to the position corresponding to the blocked mesh number in the filter screen corresponding to the rotating filter screen number, and the feedback force and unclogging distance are obtained.

[0130] The feedback force is the resistance on the unclogging mobile needle when it moves towards the mesh. It can be obtained by the pressure sensor. The unclogging distance is the distance that the unclogging mobile needle moves downwards. It can be obtained by the distance sensor.

[0131] Step 305: continue to move downwards when the feedback force is less than the breaking critical force and the unclogging distance is less than the unclogging critical distance.

[0132] The breaking critical force is the critical force at which the needle is about to break. When the feedback force is less than the breaking critical force, it means that the needle will not break even if it continues to move downwards. When the unclogging distance is less than the unclogging critical distance, it means that there is still a physical limit and the needle can continue to move downwards.

[0133] Step 306: replace the unclogging mobile needle corresponding to the new test unclogging mobile needle number to move the position corresponding to the blocked mesh number in the filter mesh corresponding to the rotating filter mesh number when the feedback force is less than the breaking critical force and the unclogging distance is equal to the unclogging critical distance.

[0134] When the unclogging critical distance is reached, it means that the mesh has been penetrated. The blocked area corresponding to the mesh has either been unclogged or was not blocked in the first place. Therefore, another unclogging mobile needle can be used to unclog.

[0135] Step 307: do not rotate when the feedback force is less than the breaking critical force and the unclogging distance is equal to the unclogging critical distance at any blocked mesh number.

[0136] When any position can be unclogged, it means that all large particle residues at all positions have been converted into small particle residues. Therefore, the filter can be directly shaken to separate the residues, and the filter does not need to be flipped to prevent damage.

[0137] Step 308: rotate the filter mesh corresponding to the filter mesh number and the cover plate around the rotation axis when the feedback force is equal to the breaking critical force and the unclogging distance is less than the unclogging critical distance at a blocked mesh number.

[0138] When one position cannot be unclogged, it means that there are still large particle residues. Therefore, the filter still needs to be flipped to reduce the amount of small particle residues that cannot fall off the large particle residues.

[0139] Reference Figure 5 The method of not rotating when the feedback force is less than the breaking critical force and the unclogging distance is equal to the unclogging critical distance at any blocked mesh number includes:

[0140] Step 400: determine the peripheral blocked mesh number based on the blocked area and the blocked mesh number. Define the test unclogging mobile needle number corresponding to the peripheral blocked mesh number as the peripheral test unclogging mobile needle number.

[0141] The outermost plugging mesh number is the number of the outermost plugging mesh in the plugging area. When there is no other mesh between the mesh and the boundary line, the outermost plugging mesh is defined as the default outermost plugging mesh, and the corresponding plugging mesh number is defined as the outermost plugging mesh number.

[0142] Step 401: determining the poking direction based on the plugging area and the outermost plugging mesh number.

[0143] The poking direction is the vertical direction from the outermost plugging mesh number to the edge of the plugging area. The determination method is to first find the corresponding coordinates of the outermost plugging mesh number from the database, and then determine the nearest distance between the boundary line of the plugging area and the coordinates corresponding to the outermost plugging mesh number. The nearest distance can also be the vertical distance from the coordinates corresponding to the outermost plugging mesh number to the boundary line.

[0144] Step 402: poking in the poking direction when the corresponding dredging moving needle of the outermost test dredging moving needle number is inserted to a preset poking distance at any outermost plugging mesh number.

[0145] The poking distance is the distance that has not been inserted into the mesh but just contacts the mesh. The purpose is to poke all the particles located at this position. The purpose of poking is to scatter the outermost excess material without sticking together.

[0146] Step 403: reacquiring the plugging area based on the outermost test dredging moving needle number after all outermost test dredging moving needle numbers are poked, and updating the outermost test dredging moving needle number until there is no plugging area or the poking cannot be performed.

[0147] The purpose of re-determination is that only the outermost part is poked, so the inside is still a plugging area, and it still needs to be poked and scattered.

[0148] Reference Figure 6 The method of poking in the poking direction when the corresponding dredging moving needle of the outermost test dredging moving needle number is inserted to a preset poking distance at any outermost plugging mesh number comprises the following steps:

[0149] Step 500: arbitrarily selecting two adjacent outermost test dredging moving needle numbers and calculating the poking angle difference according to the respective poking directions, and defining the selected adjacent outermost test dredging moving needle numbers as selected dredging moving needle numbers.

[0150] The poking angle difference is the difference between the angles of the two poking directions, which is the absolute value obtained by subtracting the two poking directions.

[0151] Step 501: form a plurality of peripheral test unblocking moving needle number groups based on the dialing angle difference, the peripheral test unblocking moving needle number groups comprising peripheral test unblocking moving needle numbers sequentially adjacent at the beginning and end, and the dialing angle difference formed by any two corresponding dialing directions of the peripheral test unblocking moving needle numbers in the same peripheral test unblocking moving needle number group being less than the preset influence critical angle.

[0152] The peripheral test unblocking moving needle number group is a combination of the unblocking moving needles corresponding to the peripheral test unblocking moving needle numbers dialing at the same time, and the purpose of forming is to facilitate classification. The forming method is to compare the dialing angle difference corresponding to the dialing directions of any two adjacent peripheral test unblocking moving needle numbers with the preset influence critical angle. If it is less than, it is classified into a group, and then the adjacent peripheral test unblocking moving needle numbers in the group are found, and the dialing angle difference is compared. If it is less than, it is classified into the same group. If it is greater than, a new group is established. Here, each peripheral test unblocking moving needle number newly entering must have a dialing angle difference corresponding to each peripheral test unblocking moving needle number in the same group, which is less than the influence critical angle, so that all dialing directions are almost similar.

[0153] Step 502: determine the moderate dialing direction according to the dialing directions of the peripheral test unblocking moving needle numbers in the same peripheral test unblocking moving needle number group, and the sum of the angle difference values between the moderate dialing direction and any dialing direction is the smallest.

[0154] The moderate dialing direction is the direction with the smallest sum of angle difference values between any dialing direction. The calculation method is to take the middle value in the dialing directions corresponding to the middle two peripheral test unblocking moving needle numbers.

[0155] Step 503: dial the moderate dialing direction when the unblocking moving needles corresponding to the peripheral test unblocking moving needle numbers in the same peripheral test unblocking moving needle number group are inserted to the unblocking critical distance.

[0156] Here, the unblocking moving needles corresponding to the peripheral test unblocking moving needle numbers in the same peripheral test unblocking moving needle number group are moved in the same direction, which directly helps each other on the one hand, and reduces the moving distance of the unblocking device on the other hand.

[0157] Reference Figure 7 The further method of rotating the filter screen corresponding to the filter screen number and the cover plate around the rotation shaft comprises:

[0158] Step 600: determining the closest filter screen edge line based on the blocked area, the preset horizontal filter screen area and the rotation axis of the rotating shaft, and defining the filter screen edge line as the impact filter screen edge line.

[0159] The impact filter screen edge line is the edge line closest to the blocked area among two edge lines parallel to the rotating shaft. The determination method is to first determine the two parallel edge lines according to the rotating shaft, then calculate the vertical distances from the center point of the blocked area to the two edge lines, and then select the smaller value among the two vertical distances as the impact filter screen edge line.

[0160] Step 601: determining the rotating direction based on the impact filter screen edge line.

[0161] The rotating direction is the direction of the rotation of the filter screen. Here, the rotating direction is the direction in which the impact filter screen edge line is located at the lowermost position when the filter screen is vertical. The purpose of how to rotate here is to make the large particle residues corresponding to the blocked area not move too far when the filter screen is rotated to vertical, so as to cause greater impact on the filter screen.

[0162] Step 602: rotating the filter screen and the cover plate corresponding to the filter screen number around the rotating shaft according to the rotating direction and the preset initial rotating speed, and obtaining the rotating angle and the self-shaking information.

[0163] The rotating angle is the angle experienced by the filter screen corresponding to the filter screen number since the horizontal direction. Here, it can be obtained by an angle sensor. The self-shaking information is the information of the vibration amplitude of the filter screen. Here, it can be received by a vibration sensor. The purpose of obtaining is to reduce the impact of the large particle residues on the filter screen during the turning process.

[0164] Step 603: continuing to rotate and continuously obtaining the rotating angle and the self-shaking information when the amplitude and the frequency corresponding to the self-shaking information are less than the amplitude and the frequency corresponding to the preset critical impact information.

[0165] The critical impact information is the amplitude and the frequency corresponding to the impact force set by human beings. Here, the value is obtained by human beings through long-term experiments, that is, the impact force when the service life of the filter screen is greatly reduced after observing the filter screen after different sizes and frequencies of impact is recorded. When it is less than the critical impact information, it means that the damage to the filter screen is smaller, and the rotation can be continued,

[0166] Step 604: obtaining the reduced rotating speed based on the preset reducing speed span and the initial rotating speed when the amplitude and the frequency corresponding to the self-shaking information are greater than the amplitude and the frequency corresponding to the critical impact information.

[0167] The reduced speed span is the span of the single reduced speed value. The reduced rotation speed is the speed reduced from the original initial rotation speed. The calculation method is the initial rotation speed minus the reduced speed span. The reduced speed span can also be set in the form of a proportion, for example: 0.8, and the calculation method is the initial rotation speed multiplied by the reduced speed span.

[0168] Step 605: Adjust the initial rotation speed to the reduced rotation speed, continue to rotate, and continuously acquire the rotation angle and self-shaking information.

[0169] Step 606: When the rotation angle falls within the vertical angle range, adjust the reduced rotation speed to the gentle transition speed, continue to rotate, and continuously acquire the rotation angle and self-shaking information.

[0170] The gentle transition speed is a relatively slow speed, at which the large-particle residual material in the blocking area will slowly fall without vertically falling off due to the loss of support. The vertical angle range is a range around the angle at which the filter screen is kept in the vertical direction, for example: 85°-95°. When falling into it, the friction of the blocking area is the smallest at this time. In order to make the blocking area not easy to lose support due to the sudden falling into the angle corresponding to the area, thereby rapidly falling, it is necessary to adjust the rotation speed to the gentle transition speed, so that the blocking area has been supported by the edge line of the impact filter screen, and will not cause a larger impact.

[0171] Step 607: When the rotation angle is away from the vertical angle range, adjust the gentle transition speed to the reduced rotation speed before falling into the vertical angle range, continue to rotate, and continuously acquire the rotation angle and self-shaking information.

[0172] When rotated, in order to ensure the same as before falling in, the speed is adjusted to the reduced rotation speed, and then the observation is continued.

[0173] Reference Figure 8 The method of adjusting the initial rotation speed to the reduced rotation speed and continuing to rotate includes:

[0174] Step 700: When the reduced rotation speed is less than the preset minimum critical speed, find the corresponding hold cylinder number from the equipment database based on the rotation filter screen number.

[0175] The top cylinder number is the number of the cylinder that holds the filter screen, and drives the filter screen to move towards the side of the cover plate. The filter screen is surrounded by a plate with a sliding rail that allows the filter screen to slide towards or away from the cover plate. The bottom of the plate is fixed with a cylinder, and the piston rod of the cylinder is located on the filter screen to drive the filter screen to move. The database also stores the mapping relationship between the rotating filter screen number and the top cylinder number. The database is established in the same way as step 201, and will not be repeated here. When the system receives the corresponding rotating filter screen number, it automatically finds the corresponding top cylinder number from the database and outputs it.

[0176] The minimum critical speed is a critical speed set by humans, i.e. at this speed, although it is rotating, the rotation is not obvious, and the time for one rotation is too long. When it is less than the minimum critical speed, it means that the shaking of the large particle residue is too large, so the speed has to be reduced, and the large particle residue needs to be clamped.

[0177] Step 701: Drive the cylinder corresponding to the top cylinder number to move the filter screen corresponding to the rotating filter screen number to approach the cover plate of the corresponding filter screen, and obtain the moving distance and clamping force.

[0178] The moving distance is the distance that the filter screen moves, which can also be obtained by a displacement sensor. The clamping force is the force feedback from the filter screen, and the way of obtaining the feedback force is the same as before, and will not be repeated here.

[0179] Step 702: Stop the filter screen from moving when the clamping force is equal to the preset clamping force, and rotate the filter screen corresponding to the filter screen number and the cover plate around the rotation axis at the minimum critical speed, and reacquire the rotation angle and the shaking information.

[0180] The clamping force is the force at which the residue is clamped and does not need to be moved further. The setting of this force is essentially to prevent the filter screen from being crushed due to excessive force. When the moving distance reaches the clamping force, it means that it cannot be moved further, so the restraining force of the filter screen and the cover plate on the residue increases, and the shaking is relatively less, so the theoretical rotation speed can be higher, and thus exceed the minimum critical speed.

[0181] Step 703: When the amplitude and frequency corresponding to the shaking information are less than the amplitude and frequency corresponding to the critical impact information, increase the rotation speed based on the reduced speed span and the minimum critical speed.

[0182] The increased rotation speed is the speed increased on the basis of the minimum critical speed. The calculation method is to add the reduced speed span and the minimum critical speed. If the reduced speed span is a proportion, then the minimum critical speed is divided by the reduced speed span. When clamping, the speed can be increased to ensure that the rotation time is not too long.

[0183] Step 704: rotating according to increasing rotating speed when the amplitude and frequency corresponding to the self-shaking information are equal to the amplitude and frequency corresponding to the critical impact information until the amplitude and frequency corresponding to the self-shaking information and the amplitude and frequency corresponding to the critical impact information are different.
