[0038] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0039] Reference Figure 1 to Figure 6 , is an embodiment of the present invention, a grille dirt remover, used for cleaning debris in wastewater, comprising: a frame 1, the bottom of the frame 1 having an arc-shaped guide groove 5; a filter plate 2, having a filter groove 201, the filter plate 2 is arranged on the frame 1; a driving sprocket 11, rotatably and slidably arranged on the frame 1, the driving sprocket 11 located at the bottom of the frame 1 rotates and slides in the arc-shaped guide groove 5; a driving chain 4, the driving chain 4 is wound around the driving sprocket 11; a scraper 3, having a plurality of scrapers 3, a plurality of scrapers 3 are arranged on the driving chain 4 at intervals, and are located on one side of the filter groove 201, the scraper 3 has a rake tooth portion, after the driving sprocket 11 slides along the arc-shaped guide groove 5, the driving sprocket 11 drives the driving chain 4 and the scraper 3 away from or close to the filter plate 2, after the scraper 3 captures the debris, the scraper 3 is slidably arranged in the filter groove 201, or the scraper presses the debris onto the filter plate 2.

[0040] In the above scheme, the frame 1 plays a key role in supporting and fixing other components in the grille dirt remover. Specifically, the frame 1 and the filter plate 2 form a U-shaped groove, and the drive chain 4 and the scraper 3 are located in the U-shaped groove. The frame 1 provides a stable frame structure for the operation of the entire dirt remover. The filter plate 2 is arranged on the frame 1 so that the filter plate 2 can be stably located at a specific position in the wastewater circulation process. Specifically, when in use, the frame 1 and the filter plate 2 are both arranged at an angle, and the angle between the wastewater surface and the filter plate 2 is an obtuse angle to achieve effective interception of debris. The frame 1 provides a mounting plane for the filter plate 2 to ensure that the position and direction of the filter tank 201 are correct, thereby ensuring that the wastewater can flow smoothly through the filter plate 2 and the debris can be intercepted on one side of the filter tank 201.

[0041] The filter plate 2 is an important component of the grille dirt remover, and a filter tank 201 is arranged on it. The filter tank 201 allows wastewater to pass smoothly while intercepting various debris. In practical applications, the filter plate 2 can be made of a sturdy and corrosion-resistant metal material, such as stainless steel. The stainless steel material can ensure that the filter plate 2 can work stably for a long time in a humid and corrosive wastewater environment. The shape of the filter tank 201 is a long rectangular tank, and its width and depth are designed according to the wastewater debris that needs to be processed and the processing flow rate. For example, when processing wastewater containing a large amount of medium-sized debris, the width of the filter tank 201 can be designed to be 3-7 cm, and the depth can be designed to be 15-20 cm.

[0042] The grid dirt remover is provided with a plurality of scrapers 3, which are circularly slidably arranged on one side of the filter tank 201. Each scraper 3 has a rake tooth portion 301, which is used to capture debris. The rake tooth portion 301 can be composed of a plurality of metal teeth arranged at a certain angle, and the distance between the teeth is designed according to the size of common debris. For example, when treating wastewater containing more small branches, plastic bags and other debris, the distance between the teeth can be set to 2-5 cm. The main part of the scraper 3 can be made of the same stainless steel material as the filter plate 2 to ensure the overall strength and corrosion resistance.

[0043] In the actual sewage treatment environment, the frame 1 needs to bear the weight of various components and the forces generated during operation, such as the pulling force of the scraper 3 when cleaning debris, the pressure of the filter plate 2 under the impact of wastewater, etc. The drive chain 4 is arranged on the inner wall of the frame 1 and is located on one side of the filter plate 2. The drive chain 4 is to effectively drive the scraper 3 to move. As a power transmission component for the circular movement of the scraper 3, the drive chain 4 transmits power to the scraper 3 so that the scraper 3 can move in a circular manner. It should be noted that when large debris such as oil drums, plastic barrels or tires enter the scraper 3, the chain moves counterclockwise, that is, the scraper 3 moves up along the filter plate 2, and the large volume of debris will lift the bottom of the drive chain 4. At the same time, due to the large weight of the scraper 3, the scraper 3 can squeeze the oil drum on the surface of the filter plate 2 and drive the oil drum to move up, thereby cleaning the large volume of debris.

[0044] The bottom of the frame 1 is provided with an arc guide groove 5, which provides a preset motion track for the drive sprocket 11. When the length of each chain section is small, in order to prevent the drive chain 4 from being loosened or kinked after deflection, arc guide grooves 5 are set on both sides of the bottom of the frame 1 to limit the motion track of the drive sprocket 11 to an arc, so that the movement of the drive sprocket 11 is more precise and controllable. In the structural system of the entire grille dirt remover, the arc guide groove 5 serves as a guide component to ensure that the drive sprocket 11 slides on a predetermined path. The overall structure of the arc guide groove 5 and the frame 1 is an integrated structure. The arc guide groove 5 is closely matched with the drive sprocket 11, and indirectly affects the movement of the drive chain 4 and the scraper 3 by providing space for the drive sprocket 11 to slide and rotate. Because the movement of the drive sprocket 11 is directly related to the tensioning of the drive chain 4 and the position adjustment of the scraper 3, the arc guide groove 5 plays a role in regulating and guiding the operation mechanism of the entire equipment. For example, without the precise guidance of the arc guide groove 5, the drive sprocket 11 may move irregularly, which will cause unstable tension of the drive chain 4, thereby affecting the normal operation of the scraper 3, and the scraper 3 may not be able to accurately approach or move away from the filter plate 2 to clean up debris.

[0045] Working process: First of all, it should be noted that half of the grille dirt remover of the present invention is located below the water surface. When the grille dirt remover starts working, the wastewater flows through the filter plate 2, and the debris in the water is intercepted by the filter plate 2 on one side of the filter tank 201. At this time, the scraper 3 starts to circulate under the drive of the drive chain 4 and the drive sprocket system. Since the grille dirt remover of the present invention can not only filter smaller debris, but also filter larger debris, and debris of different volumes will appear in the wastewater. Layered, smaller debris will float in the middle and upper layers of the wastewater, while larger and heavier debris will remain at the bottom of the wastewater. When the scraper 3 moves to a position close to the filter tank 201, the rake tooth portion 301 will intercept and capture the debris. For smaller debris, such as leaves, plastic bags, etc., the scraper 3 will directly carry them, and as the scraper 3 moves, these debris will move up along the filter plate 2 with the scraper 3. For larger debris, such as larger plastic bottles, cans, old tires or waste barrels, after the scraper 3 captures these debris, these debris will lift up the scraper 3 and the chain, and the scraper 3 will press these debris onto the filter plate 2. When the scraper 3 continues to move, the scraper 3 will drive these large debris to move up along the filter plate 2 until they are moved out of the frame 1 from the discharge side 14. The grid dirt remover of the present invention can effectively solve the problem that the existing grid dirt remover is difficult to clean large debris, and realizes the rapid and thorough cleaning of debris of different volumes in wastewater.

[0046] In the above working process, the continuous operation of the drive chain 4 is the driving force for the scraper 3 to continuously clean up the debris. The drive chain 4 is like a conveyor belt, moving the scraper 3 from one position to another, so that the scraper 3 can clean up the debris at different positions on the filter plate 2. Several scrapers 3 are arranged at intervals on the drive chain 4. This interval arrangement is to ensure that the scraper 3 can evenly cover one side of the filter tank 201 of the filter plate 2 during the circulation process to avoid the occurrence of cleaning dead corners. Driven by the drive chain 4, each scraper 3 passes through the outside of the filter tank 201 in turn to capture and clean up the debris.

[0047] Furthermore, if the chain links use a longer rod body, then the arc guide groove 5 is not required, and the sprocket at the bottom of the frame 1 is also not required, so that there is no sprocket and bearing in the water, thereby improving the dredging ability and the overall service life of the device.

[0048] It is understandable that during the operation of the equipment, the rotation of the drive sprocket 11 is continuous to ensure the stable operation of the drive chain 4. Sliding is an adjustment action that needs to be performed according to the size of the debris volume, such as during the equipment installation and commissioning stage or during the operation of the equipment according to the actual situation of debris cleaning. When the drive sprocket 11 slides along the arc guide groove 5, it will drive the drive chain 4 and the scraper 3 away from or close to the filter plate 2. This motion adjustment capability makes the grille dirt remover flexible. When dealing with debris of different types and accumulation levels, the distance between the scraper 3 and the filter plate 2 can be adjusted according to the actual situation.

[0049] For example, when a large amount of large debris is accumulated on the filter plate 2, the debris will lift up the scraper 3, and the scraper 3 is moved away from the filter plate 2 by driving the sliding of the sprocket 11, so as to better accommodate and compact the large debris or more effectively bring the debris to the surface of the filter plate 2. On the contrary, when the volume of the debris is small, the scraper 3 can always be kept close to the filter plate 2. This adjustable mechanism improves the adaptability of the grille dirt remover to different working conditions and enhances the practicality of the equipment.

[0050] Furthermore, a material opening 13 is provided between two adjacent scrapers 3, and the material opening 13 is used for the passage of debris.

[0051] In the above scheme, the debris located in different layers of the wastewater, except for the heavier or larger debris in the bottom layer, the debris in the remaining layers will enter the filter plate 2 through the material port 13, and then be scraped out of the frame 1 by the scraper 3. Only the larger and heavier debris will lift the bottom of the drive chain 4.

[0052] Furthermore, it also includes: a mounting plate 6, a driving sprocket 11 located above the frame 1 is rotatably set on the mounting plate 6; a connecting rod 8, one end of which is hinged on the frame 1, and the other end is hinged on the mounting plate 6. After the driving chain 4 moves away from the filter plate 2, the connecting rod 8 drives the mounting plate 6 to swing to the side away from the frame 1; a motor 7 is set on the mounting plate 6, and the driving sprocket 11 located above the frame 1 is set on the output end of the motor 7.

[0053] In the above scheme, the mounting plate 6 is located above the frame 1, providing an installation position for the drive sprocket 11 located above the frame 1. It is a supporting structure for the drive sprocket 11. When the drive chain 4 is lifted up, the mounting plate 6 can also swing under the drive of the connecting rod 8 to meet the needs of the chain. One end of the connecting rod 8 is hinged to the frame 1, and the other end is hinged to the mounting plate 6. This hinged connection method allows the connecting rod 8 to rotate flexibly within a certain range to achieve the swing of the mounting plate 6. It should be noted that due to the large deadweight of the scraper 3 of the present invention, in the absence of large volume debris to lift the drive chain 4, the scraper 3 is always in sliding contact with the filter plate 2. In the entire equipment structure, the connecting rod 8 plays a role as a bridge for connection and transmission. The hinged design can adapt to different motion states to ensure that the connecting rod 8 will not generate excessive stress due to the rigid connection during the operation of the equipment.

[0054] When the drive chain moves away from the filter plate 2, the connecting rod 8 drives the mounting plate 6 to swing away from the frame 1. The connecting rod 8, as a transmission component, converts the motion state of the drive chain into the swinging motion of the mounting plate 6. For example, when the scraper 3 and the filter plate 2 need to be adjusted, the mounting plate 6 can be moved away from the frame 1 by moving the drive chain 4 and the connecting rod 8, thereby providing a larger accommodating space for large-volume debris between the scraper 3 and the filter plate 2.

[0055] By installing the motor 7 on the mounting plate 6, the motor 7 can be directly connected to the driving sprocket 11 located above the frame 1, reducing energy loss and component complexity during power transmission. The installation position of the motor 7 is close to the driving sprocket 11, which is convenient for efficiently transmitting the output power of the motor 7 to the driving sprocket 11 through a coupling or other transmission device. At the same time, when the driving chain 4 is away from the filter plate 2, the mounting plate 6 will be driven by the connecting rod 8 to move away from one side of the filter plate 2. Installing the motor 7 on the mounting plate 6 can ensure that the motor 7 swings together, and ensure that the motor 7 is always connected to the driving sprocket 11 to achieve uninterrupted power output.

[0056] Furthermore, it also includes: a swing rod 9, which is rotatably set on the frame 1; a push plate, which is set on the swing rod 9, and the push plate 10 is located above the drive chain 4. After the scraper 3 moves to above the filter plate 2, the push plate is used to push the debris on the scraper 3 out of the frame 1.

[0057] In the above scheme, the swing rod 9 is rotatably arranged on the frame 1. This rotational arrangement enables the swing rod 9 to swing around the connection point on the frame 1. The swing rod 9 plays a role of connection and transmission in the entire grille decontamination machine. As an intermediate component, it transmits its own rotational motion to the push plate, thereby realizing the push plate's pushing action on the debris on the scraper 3. The push plate is arranged on the swing rod 9 and is located above the drive chain 4. When the scraper 3 moves above the filter plate 2, due to the inclined arrangement of the scraper 3, the scraper 3 will apply an oblique outward force to the scraper 3 during the upward movement, and the push plate can effectively interact with the scraper 3. Until the debris on the scraper 3 is pushed out of the frame 1, this is the last key step in the entire grille decontamination machine debris processing process. For example, in the sewage treatment process, the scraper 3 collects the intercepted debris and moves it above the filter plate 2. At this time, the scraper 3 guides the outward movement and pushes the debris on the scraper 3 to the outside of the equipment, thereby completing the debris removal work and preventing the debris from accumulating inside the equipment and affecting the normal operation of the equipment. A torsion spring or a tension spring is also provided on the swing rod 9. When the push plate 10 and the scraper 3 slip off, the swing rod 9 will drive the push plate to reset and prepare for the next push.

[0058] Furthermore, the scraper 3 is L-shaped and has a bending surface. The bending angle of the bending surface is 120°-150°. After the scraper 3 abuts against the push plate, the bending surface guides the scraper 3 to move toward the outside of the frame 1.

[0059] In the above scheme, the L-shaped structure enables the scraper 3 to effectively capture debris on one side of the filter plate 2, and one side of the scraper 3 can penetrate into the debris accumulation area, using a larger surface area to intercept and gather debris. When dealing with floating objects and suspended matter in sewage, the L-shaped scraper 3 can gather debris together like a small shovel, thereby improving the efficiency of debris cleaning. This shape can also adapt to debris of different shapes and sizes to a certain extent. Compared with the scraper 3 of a simple shape, the L-shaped scraper 3 can contact and handle debris more comprehensively. The scraper 3 has a bending surface, and the bending angle is 120°-150°. This bending surface and the specific bending angle are carefully designed. Within the bending range of 120°-150°, on the one hand, the bending surface can effectively guide the scraper 3 to move to the outside of the frame 1 when the scraper 3 abuts against the push plate. When the push plate pushes the scraper 3, this bending surface is like a guiding slope, allowing the scraper 3 to move smoothly in a predetermined direction. A suitable bending angle can make the scraper 3 have better structural strength and stability when it is subjected to the pressure and friction of debris. If the bending angle is too small, the scraper 3 may be fragile and easily damaged; if the bending angle is too large, it may affect the contact and guiding effect between the scraper 3 and the push plate. The inclined structure of the bending surface decomposes the thrust applied by the push plate into a horizontal component toward the outside of the frame 1 and a vertical component. The horizontal component enables the scraper 3 to move smoothly toward the outside of the frame 1, thereby removing the debris on the scraper 3 from the frame 1.

[0060] Furthermore, a discharge side 14 is located between the top of the filter plate 2 and the frame 1 , and further includes: a discharge plate 12 slantingly disposed on the discharge side 14 , and the discharge plate 12 is used to guide debris to be discharged from the frame 1 .

[0061] In the above solution, after the pushing plate pushes out the debris, the debris falls to the outside of the frame 1 under the guidance of the discharging plate 12 .

[0062] Furthermore, the bottom of the frame 1 has an arc-shaped bottom groove 101 , and the scraper 3 is slidably abutted against the arc-shaped bottom groove 101 .

[0063] In the above scheme, the scraper 3 is kept in contact with the arc bottom groove 101 at different working stages, such as capturing debris, transporting debris, etc., and the abutting state ensures that the scraper 3 has stable support during the movement. Since the scraper 3 may be subjected to pressure from debris, its own gravity, and the force generated by the interaction with other components during operation, the abutment with the arc bottom groove 101 can disperse these forces, prevent the scraper 3 from shaking or deflecting, and ensure that the scraper 3 can stably perform its function of cleaning debris.

[0064] Furthermore, the filter groove 201 is a through groove opened along the length direction of the filter plate 2 .

[0065] In the above scheme, it is not only convenient to filter the debris, but also convenient for the rake teeth 301 to be slidably connected with the through groove.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
