[0026] The following describes embodiments of the present invention with reference to the accompanying drawings. Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the screen machine 100 is used to intercept and salvage debris from the water to clean sewage. The screen machine 100 includes: a frame 1, a screen assembly 3, a rotary drive device 4, an inner slag trough 5, a brush device 6, a photoelectric detection device and a control module. The screen assembly 3 is installed in the frame 1, and the screen assembly 3 includes: a plurality of screen plates 31, and the screen plates 31 have a plurality of screen holes 32. The plurality of screen plates 31 are arranged in sequence and are adjacent to each other end to end to form a rotation space 20. The rotary drive device 4 is arranged on the frame 1, and the rotary drive device 4 drives the screen assembly 3 to transmit in the direction of the bottom of the frame 1 and the top of the frame 1. The inner slag trough 5 is connected to the frame 1 and is arranged in the rotation space 20 to receive the debris dropped from the screen assembly 3. The brush device 6 includes: a brush 61 arranged in the rotation space 20, and a brush drive member 62 that drives the brush 61 to rotate. The brush 61 is used to clean the side of the screen plate 31 facing the rotation space 20. As shown Figure 2 and Figure 3 As shown, Figure 2The figure shows a part of the grid plate to reflect the position of the light source. The photoelectric detection device includes: a detection member 71 arranged on the frame 1 and a light source arranged on the inner slag tank 5. The detection member 71 can be a photoelectric sensor. The grid plate 31 is located between the detection member 71 and the light source 72. The photoelectric sensor is used to detect the light from the light source passing through the grid hole 32. The control module is electrically connected to the rotary drive device 4, the brush drive member 62, the light source 72, and the detection member 71 and the light source 72 of the photoelectric detection device. The control module is used to control the start and stop of the photoelectric detection device, and obtain the light transmission signal detected by the photoelectric sensor and the current hole value of the grid hole 32 that can transmit light in each grid plate 31. When the current hole value is less than the preset hole value, and the current plate value of the grid plate 31 with less than the preset hole number is less than the preset plate value, the control module controls the brush drive member 62 to drive the brush 61 to rotate and clean the grid plate 31. Since a photoelectric detection device is provided, the structural features of the grid assembly 3 are utilized to detect light passing through the grid holes 32 of the grid plate 31, so that the residual debris on the grid plate 31 can be known, and the brush 61 is driven to clean the debris on the grid plate 31, so that the grid plate 31 will not be left with too much debris, causing excessive load and affecting the service life. Cleaning the debris on the grid plate 31 also allows the system to maintain more effective sewage treatment for a long time when treating sewage.

[0027] In this embodiment, if Figure 1 and Figure 2 As shown, at least part of the plurality of grid holes 32 is arranged along the extension direction of the brush 61 to form a grid hole group. Each grid plate 31 has a plurality of grid hole groups, that is, as shown in FIG. Figure 1 The light source 72 extends along the extension direction of the brush 61. When the grid plate 31 rotates to a certain position, the light emitted by the light source is aligned with at least one row of grid holes 32 arranged in the horizontal direction, and the photoelectric sensor is also aligned with the row of grid holes 32 for detection. The light source 72 can be a laser or an LED with multiple emission points. In this embodiment, the grid holes 32 are arranged horizontally, but in other embodiments, they may not be arranged horizontally. In other embodiments, the photoelectric detection device can also be the transmitting end and the receiving end of the grating sensor. No matter which is the receiving end and which is the transmitting end, they are arranged along the arrangement direction of the grid holes 32 in the grid hole 32 group. The matching form of the photoelectric detection device shall be based on the actual use requirements and will not be described here one by one.

[0028] Furthermore, if Figure 1 and Figure 4As shown, the rack 1 includes: a frame 11 with an installation space, and a pair of fixed plates 12 arranged on the two side end surfaces of the frame 11, and a pair of guide rails 9 spaced relatively along a first direction are arranged at the bottom of the frame 11. The rotary drive device 4 includes: a pair of rotary chains 44 and a rotary power member 43. Each rotary chain 44 is arranged in the installation space and extends along the height direction of the rack 1, and each rotary chain 44 rotates along its corresponding guide rail 9. The pair of rotary chains 44 are spaced along the first direction, and the two ends of each grid plate 31 are respectively connected to the pair of rotary chains 44. The rotary power member 43 penetrates the fixed plate 12 to drive the rotary chain 44, and is electrically connected to the control module.

[0029] like Figure 4 As shown, the grille machine 100 further includes: a nozzle device 8 arranged on the top of the frame 1 , and the nozzle device 8 is used to flush the grille plate 31 .

[0030] Specifically, Figure 1 , Figure 2 As shown, the notch of the inner slag trough 5 faces the top of the frame 1, and the two end surfaces of the inner slag trough 5 respectively have a sewage channel 51 and a water flow channel 52. The rotary drive device 4 also includes: a pair of adjustment plates 42 respectively connected to a pair of fixed plates 12 and a rotary sprocket 41 driven by a rotary power member 43, the rotary power member 43 is fixed to the adjustment plate 42, and the rotary sprocket 41 is meshed with a rotary chain 44. Figure 4 As shown, the rotary power member 43 includes a motor 431 and a connecting shaft 432. The motor 431 is connected to the connecting shaft 432. The connecting shaft 432 passes through the rotary sprocket 41. The rotary chain 44 is sleeved on the rotary sprocket 41. The motor 431 drives the connecting shaft 432 to rotate. The connecting shaft 432 rotates to drive the rotary sprocket 41. The rotary sprocket 41 drives the rotary chain 44 to rotate in a circle. Figure 1 The arrow A in the middle is the direction. When the grating plate 31 is driven by the rotating chain 44 to rotate, the sewage intercepts the debris through the grating plate 31, and the grating plate 31 brings the debris to the top during rotation. The debris falls from the top into the inner slag tank 5, and the water in the inner slag tank 5 is flushed through the water flow channel 52 to be discharged through the sewage discharge channel 51. In addition, the nozzle device 8 has multiple nozzles, which can flush the debris on the grating plate 31 into the inner slag tank 5.

[0031] In addition, the control module controls the brush drive 62 to adjust the speed of the brush 61, and the speed of the brush 61 is negatively correlated with the current hole value. Specifically, in this embodiment, the brush drive 62 can be a motor, and the speed can be set to three gears, that is, the brush 61 can have three speeds, from low to high, respectively, the first gear, the second gear and the third gear, wherein the current hole value corresponding to the first gear is the highest, and the current hole value corresponding to the third gear is the lowest. That is, when the number of grid holes 32 blocked by debris on the grid plate 31 is the least, and the degree of debris adhesion on the grid plate 31 is low, the speed of the brush 61 can be lower to clean the grid plate 31; when the number of grid holes 32 blocked by debris on the grid plate 31 is the largest, and the degree of debris adhesion on the grid plate 31 is high, the speed of the brush 61 needs to be faster and have a stronger cleaning force to clean the grid plate 31, so that the standard for cleaning the grid plate 31 matches the degree of debris adhesion, and reasonable cleaning is achieved. In addition, in order to match the speed gear of the brush 61, different levels of preset level hole value ranges are set. For example, three speed gears are equipped with three preset level hole value ranges, and one speed gear is matched with one preset level hole value range. When the current hole value is within one of the preset level hole value ranges, the brush 61 is adjusted to the speed of the brush 61 matched with the preset level hole value range. It can be understood that in other embodiments, the speed of the brush 61 can have more gears, and the preset level hole value range can also have more levels, which is not limited to the settings in this application. In addition, according to needs, the brush 61 can also work at the same speed, which does not match the degree of debris adhesion of the grille plate 31.

[0032] Furthermore, when cleaning the grille plate 31 , the control module can control the rotary drive device 4 to start the grille assembly 3 and open the cleaning water valve, and the nozzle of the nozzle device 8 simultaneously flushes the grille plate 31 to cooperate with the brush 61 .

[0033] Furthermore, if Figure 5 As shown, the grill machine 100 also includes: a torque sensor (not shown in the figure) electrically connected to the control module, and the torque sensor is used to detect the torque of the rotary drive device 4. The control module is used to obtain the current torque value measured by the torque sensor. When the brush 61 works for a preset time, the current hole value or the current plate value remains unchanged, the control module determines whether the current torque value obtained is outside the preset torque value range, and if so, sends an alarm message.

[0034] Furthermore, the alarm information includes: information on replacing the brush 61 and information on cleaning the brush 61. When the current torque value obtained by the control module is less than the minimum value of the preset torque value range, the information on replacing the brush 61 is sent. When the current torque value obtained by the control module is greater than the maximum value of the preset torque value range, the information on cleaning the brush 61 is sent. In other words, when the grille plate 31 is cleaned for a long time but is ineffective, it is necessary to start the torque sensor to determine whether there is a problem with the brush 61. If the current torque value detected is greater than the maximum value of the preset torque value range, that is, the brush 61 has become heavier, at this time, too much debris may be attached to the brush 61, affecting the cleaning effect, and the brush 61 needs to be processed; but when the current torque value is less than the minimum value of the preset torque value range, the brush 61 has become lighter, and the brush 61 may be depilated, which affects the cleaning effect. At this time, the staff is notified that a new brush 61 may need to be prepared for replacement.

[0035] In addition, if Figure 1 and Figure 3 As shown, each grid plate 31, the inner slag trough 5 and the brush 61 extend along the first direction, and the first direction is perpendicular to the height direction of the frame 1. The inner slag trough 5 has a connecting portion 53 fixedly connected to the frame 1 and a receiving portion 54 connected to the connecting portion 53 from top to bottom. The groove width of the connecting portion 53 is greater than the groove width of the receiving portion 54, and the sewage discharge channel 51 and the water flow channel 52 are both connected to the end surface of the receiving portion 54; the brush 61 is located below the inner slag trough 5 and is separated from the groove wall of the receiving portion 54. In this way, the inner slag trough 5 can receive more debris, and it is convenient to install the brush 61, and it is easy to operate when replacing and maintaining the brush 61. At the same time, the light source 72 is attached to the side wall of the inner slag trough 5, and the light will not be blocked by the brush 61.

[0036] The screen machine 100 in this embodiment is a screen sewage treatment system.

[0037] Another embodiment of the present invention relates to a method for cleaning a grid machine 100, such as Figure 1 and Figure 6 As shown, it is used in the above-mentioned grill machine 100, including: Step 100, obtaining a light transmission signal of a photoelectric detection device and a current hole value of the light-transmitting grid hole 32 in each grid plate 31; Step 200, determining whether the current hole value is less than the preset hole value, and whether the current plate value of the grid plate 31 with less than the preset hole number is less than the preset plate value; If yes, in step 300, the brush driving member 62 is controlled to drive the brush 61 to rotate and clean the grid plate 31; If not, the brush drive 62 is not activated.

[0038] Furthermore, step 300 controls the brush drive 62 to drive the brush 61 to rotate and clean the grille plate 31, specifically including: controlling the brush drive 62 to adjust the rotation speed of the brush 61 according to the current hole value, and the rotation speed of the brush 61 is negatively correlated with the current hole value. When the current hole value is within the range of different preset level hole values, the brush 61 is adjusted to different rotation speeds; when the current hole value is within the range of the first preset level hole value, the rotation speed of the brush 61 is increased; when the current hole value is within the range of the second preset level hole value, the rotation speed of the brush 61 is reduced; the second preset level hole value range is greater than the first preset level hole value range. In other words, when the number of grille holes 32 blocked by debris is large, the rotation speed of the brush 61 increases, but when the number of grille holes 32 blocked by debris decreases, the rotation speed of the brush 61 decreases. The rotation speed of the brush 61 is related to the degree of attachment of debris to the grille plate 31.

[0039] Specifically, in this embodiment, the brush drive member 62 can be a motor, and the speed can be set to three gears, that is, the brush 61 can have three speeds, from low to high, namely the first gear, the second gear and the third gear, wherein the current hole value corresponding to the first gear is the highest, and the current hole value corresponding to the third gear is the lowest. That is, when the number of grid holes 32 blocked by debris on the grid plate 31 is the least, and the degree of debris adhesion on the grid plate 31 is low, the speed of the brush 61 can be lower to clean the grid plate 31; when the number of grid holes 32 blocked by debris on the grid plate 31 is the largest, and the degree of debris adhesion on the grid plate 31 is high, the speed of the brush 61 needs to be faster and have a stronger cleaning force to clean the grid plate 31, so that the standard for cleaning the grid plate 31 matches the degree of debris adhesion, and reasonable cleaning is achieved. In addition, in order to match the speed gear of the brush 61, different levels of preset level hole value ranges are set. For example, three speed gears are equipped with three preset level hole value ranges, and one speed gear is matched with one preset level hole value range. When the current hole value is within one of the preset level hole value ranges, the brush 61 is adjusted to the speed of the brush 61 matched with the preset level hole value range. It can be understood that in other embodiments, the speed of the brush 61 can have more gears, and the preset level hole value range can also have more levels, which is not limited to the settings in this application. In addition, according to needs, the brush 61 can also work at the same speed, which does not match the degree of debris adhesion of the grille plate 31.

[0040] In addition, the grille machine 100 further includes: a torque sensor electrically connected to the control module, the torque sensor is used to detect the torque of the rotary drive device 4. Step 300 controls the brush drive member to drive the brush to rotate and clean the grille plate, specifically including: Step 310, when the brush 61 works for a preset time, the current hole value or the current plate value remains unchanged, and the current torque value of the torque sensor is obtained; Step 320, determine the relationship between the current torque value and the preset torque value range, If it is greater than the torque value range, in step 330, an alarm message for cleaning the brush 61 is sent; If it is less than the torque value range, in step 340 , an alarm message for replacing the brush 61 is sent.

[0041] That is to say, when the grille plate 31 has been cleaned for a long time but to no avail, it is necessary to start the torque sensor to determine whether there is any problem with the brush 61. If the current torque value detected is greater than the maximum value of the preset torque value range, that is, the brush 61 has become heavier, there may be too much debris attached to the brush 61, affecting the cleaning effect, and the brush 61 needs to be processed; but when the current torque value is less than the minimum value of the preset torque value range, the brush 61 has become lighter, and the brush 61 may have shed hair, which affects the cleaning effect. At this time, the staff is notified that they may need to prepare a new brush 61 for replacement.

[0042] The step division of the above methods is only for the purpose of clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps.
