Description

Technical Field

[0001] This utility model relates to the technical field of sludge transportation equipment, and specifically to an automatic feeding device for sludge treatment. Background Technology

[0002] Sludge drying, also known as sludge dewatering, refers to the process of removing most of the water content from sludge through processes such as filtration or evaporation. It generally refers to the use of self-evaporation facilities such as sludge drying beds. After sludge concentration, physical methods are used to further reduce the water content, facilitating sludge transportation, stockpiling, utilization, or further treatment. There are two methods of dewatering (drying): natural evaporation and mechanical dewatering. Mechanical dewatering is conventionally referred to as sludge dewatering, while natural evaporation is called sludge drying; although the methods differ, both are measures to further reduce the water content of the sludge. After drying, desulfurization, and dust removal, the dried sludge needs to be incinerated in a rotary kiln. Traditionally, sludge transportation is done directly via a chain conveyor.

[0003] In the existing technical solutions, Chinese Patent No. CN 219637070 U discloses an automatic feeding device for sludge treatment. By setting up an intermittent feeding mechanism consisting of a sealing plate and a control component and a spreading mechanism consisting of a cleaning component and a drive component to cooperate with each other, the feeding speed can be precisely controlled and the sludge raw material on the surface of the conveyor belt can be spread and cleaned.

[0004] The shortcomings of the above-mentioned existing technical solutions are as follows: Although sludge can be spread by a spreading mechanism, the use of rotating brushes as spreading components makes it difficult to apply a uniform and stable force to the sludge when in contact with it due to the limitations of the brush's own structure. This can easily lead to local accumulation or uneven dispersion, resulting in uneven distribution of sludge on the conveyor belt and affecting the efficiency and effectiveness of subsequent drying, incineration and other treatment processes. Utility Model Content

[0005] This invention provides an automatic feeding device for sludge treatment, which can solve the problem that uneven spreading and poor spreading effect caused by spreading through rotating brushes in the prior art.

[0006] An automatic feeding device for sludge treatment includes a feeding platform, a conveyor belt, a discharge hopper, and a spreading mechanism. The conveyor belt, discharge hopper, and spreading mechanism are all located on top of the feeding platform. The spreading mechanism includes a support frame, a sliding bracket, a first rotating plate, and a second rotating plate. The support frame is vertically fixed on top of the feeding platform. The sliding bracket is slidably connected to the support frame. The first rotating plate and the second rotating plate are symmetrically arranged. One side of the first rotating plate is hinged to one side of the sliding bracket, and the other side of the first rotating plate is hinged to one side of the second rotating plate. The other side of the second rotating plate is hinged to the other side of the sliding bracket. The hinge joint between the first rotating plate and the second rotating plate has a triangular structure.

[0007] Specifically, the first rotating plate includes a first slot plate and a first insert plate, and the second rotating plate includes a second slot plate and a second insert plate. One side of the first slot plate and the second slot plate are respectively hinged to the two sides of the sliding bracket. The other side of the first slot plate and the second slot plate are respectively provided with a first slot and a second slot. One side of the first insert plate is slidably connected to the first slot, and one side of the second insert plate is slidably connected to the second slot. The other side of the first insert plate is hinged to the other side of the second insert plate.

[0008] According to one embodiment of the present invention, the paving mechanism further includes a vertical rotating rod, and a vertical rotating hole is provided at the hinge of the first rotating plate and the second rotating plate, with the vertical rotating rod passing through the vertical rotating hole. The paving mechanism also includes a horizontal slider, with a horizontal groove provided at the top of the sliding bracket, and the horizontal slider slidably disposed within the horizontal groove along the conveyor belt transport direction; the vertical rotating rod is fixedly disposed at the bottom of the horizontal slider. The paving mechanism also includes a horizontal lead screw, which is rotatably disposed within the horizontal groove, and the horizontal slider has a horizontal threaded hole that is threadedly connected to the horizontal lead screw.

[0009] According to one embodiment of the present invention, the paving mechanism further includes an adjusting handwheel, which is rotatably connected to the sliding bracket and coaxially fixedly connected to the horizontal lead screw.

[0010] According to one embodiment of the present invention, the paving mechanism further includes a first motor, which is fixedly connected to the sliding bracket, and the output end of the first motor is fixedly connected to the horizontal lead screw on the same axis.

[0011] According to one embodiment of the present invention, the paving mechanism further includes a vertical slider, and a vertical groove is provided on the side of the support frame for sliding engagement with the vertical slider. The vertical slider is fixedly disposed on the side of the sliding bracket. The paving mechanism further includes a vertical lead screw, which is rotatably disposed within the vertical groove. The vertical slider has a vertical threaded hole for threaded engagement with the vertical lead screw. The paving mechanism further includes a second motor, which is fixedly connected to the support frame, and the output end of the second motor is coaxially fixedly connected to the vertical lead screw.

[0012] The advantages of this utility model compared to the prior art are:

[0013] The triangular hinge structure enables the first and second rotating plates to form a stable paving plane under the drive of the sliding support. The mechanical thrust of the rigid plate is used to force the sludge to be leveled, avoiding the problem of uneven paving force caused by the flexible contact of traditional brushes. This can significantly improve the uniformity and efficiency of subsequent drying and incineration.

[0024] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0025] like Figures 1 to 6 As shown, an automatic feeding device for sludge treatment includes a feeding platform 1, a conveyor belt 2, a discharge hopper 3, and a spreading mechanism 4. The conveyor belt 2, the discharge hopper 3, and the spreading mechanism 4 are all located on the top of the feeding platform 1. The spreading mechanism 4 includes a support frame 5, a sliding bracket 6, a first rotating plate 7, and a second rotating plate 8. The support frame 5 is vertically fixed on the top of the feeding platform 1. The sliding bracket 6 is slidably connected to the support frame 5. The first rotating plate 7 and the second rotating plate 8 are symmetrically arranged. One side of the first rotating plate 7 is hinged to one side of the sliding bracket 6, and the other side of the first rotating plate 7 is hinged to one side of the second rotating plate 8. The other side of the second rotating plate 8 is hinged to the other side of the sliding bracket 6. The hinge point of the first rotating plate 7 and the second rotating plate 8 has a triangular structure.

[0026] Specifically, the first rotating plate 7 includes a first slot plate 9 and a first insert plate 10, and the second rotating plate 8 includes a second slot plate 11 and a second insert plate 12. One side of the first slot plate 9 and the second slot plate 11 are respectively hinged to both sides of the sliding bracket 6. The other side of the first slot plate 9 and the second slot plate 11 are respectively provided with a first slot 13 and a second slot 14. One side of the first insert plate 10 is slidably connected to the first slot 13, one side of the second insert plate 12 is slidably connected to the second slot 14, and the other side of the first insert plate 10 is hinged to the other side of the second insert plate 12.

[0027] It should be specifically noted that conveyor belt 2 is existing publicly available technology in the prior art documents, therefore its structure has not been fully described in this case.

[0028] When the conveyor belt 2 runs to the bottom of the discharge hopper 3, the sludge falls from the outlet of the discharge hopper 3 and accumulates on the conveyor belt 2. At this time, the sliding bracket 6 slides vertically along the support frame 5, driving the symmetrically arranged first rotating plate 7 and second rotating plate 8 to rise and fall synchronously, adjusting the distance between the bottom of the first rotating plate 7 and the second rotating plate 8 and the surface of the conveyor belt 2 to the preset paving thickness.

[0029] Since the first rotating plate 7 and the second rotating plate 8 form a stable triangular structure through the hinge point, when the accumulated sludge moves with the conveyor belt 2 to the bottom of the plate, the bottom edge of the triangular structure (i.e. the bottom edge of the first rotating plate 7 and the second rotating plate 8) exerts a lateral thrust on the sludge, spreading the sludge higher than the bottom of the plate evenly to both sides.

[0030] Meanwhile, by sliding the first insert plate 10 and the first slot 13, and the second insert plate 12 and the second slot 14, the overall length of the first rotating plate 7 and the second rotating plate 8 can be changed, thereby adapting to the sludge spreading requirements of different flow rates and ensuring that the sludge forms a flat layer of uniform thickness on the conveyor belt 2.

[0031] The triangular hinge structure enables the first rotating plate 7 and the second rotating plate 8 to form a stable paving plane under the drive of the sliding support 6. The mechanical thrust of the rigid plate is used to force the sludge to be leveled, avoiding the problem of uneven paving force caused by the flexible contact of traditional brushes. This can significantly improve the uniformity and efficiency of subsequent drying and incineration.

[0032] According to one embodiment of the present invention, both the first slot 13 and the second slot 14 are cross-shaped structures, thereby restricting the sliding of the first insert plate 10 and the second insert plate 12 in the vertical direction. Therefore, when the sliding bracket 6 slides vertically on the support frame 5, the first slot plate 9 and the second slot plate 11 achieve synchronous sliding with the sliding bracket 6 in the vertical direction through the hinge between them. The first insert plate 10 and the second insert plate 12 achieve synchronous sliding with the first slot plate 9 and the second slot plate 11 in the vertical direction through the cross-shaped first slot 13 and the second slot 14.

[0033] According to one embodiment of the present invention, the paving mechanism 4 further includes a vertical rotating rod 15, and a vertical rotating hole 16 is provided at the hinge of the first rotating plate 7 and the second rotating plate 8. The vertical rotating rod 15 passes through the vertical rotating hole 16. The paving mechanism 4 also includes a horizontal slider 17, and a horizontal groove is provided at the top of the sliding bracket 6. The horizontal slider 17 is slidably disposed in the horizontal groove along the transport direction of the conveyor belt 2, and the vertical rotating rod 15 is fixedly disposed at the bottom of the horizontal slider 17. The paving mechanism 4 also includes a horizontal lead screw 18, which is rotatably disposed in the horizontal groove. The horizontal slider 17 has a horizontal threaded hole that is threadedly connected to the horizontal lead screw 18.

[0034] When the horizontal lead screw 18 rotates, it drives the horizontal slider 17 to slide within the horizontal groove through its threaded engagement with the horizontal slider 17. This causes the hinge point of the first rotating plate 7 and the second rotating plate 8 to translate along the direction of the conveyor belt 2. At this time, due to the hinged relationship between the first rotating plate 7 and the second rotating plate 8 and the sliding bracket 6, the two plates will rotate around the hinge point, changing their angle with the transport direction of the conveyor belt 2. This adjusts the angle of sludge spreading, thereby adapting to the sludge spreading requirements of different flow rates and ensuring that the sludge forms a uniform and flat layer on the conveyor belt 2.

[0035] For high-viscosity sludge, increasing the paving angle can reduce resistance and prevent sludge accumulation; for low-viscosity sludge, decreasing the paving angle can increase the lateral spreading effect and improve paving uniformity.

[0036] According to one embodiment of this utility model, the paving mechanism 4 further includes an adjusting handwheel 19, which is rotatably connected to the sliding bracket 6 and coaxially fixedly connected to the horizontal lead screw 18. When the operator manually rotates the adjusting handwheel 19, the horizontal lead screw 18 rotates synchronously, driving the horizontal slider 17 to slide within the horizontal groove through threaded transmission with the horizontal slider 17, thereby adjusting the position of the hinge point of the first rotating plate 7 and the second rotating plate 8 and changing the paving angle.

[0037] According to one embodiment of the present invention, the paving mechanism 4 further includes a first motor 20, which is fixedly connected to the sliding bracket 6, and the output end of the first motor 20 is coaxially fixedly connected to the horizontal lead screw 18. When the first motor 20 is started, it drives the horizontal lead screw 18 to rotate, and through the threaded engagement with the horizontal slider 17, the horizontal slider 17 slides in the horizontal groove, thereby moving the hinge point of the first rotating plate 7 and the second rotating plate 8 to achieve the adjustment of the paving angle.

[0038] According to one embodiment of the present invention, the paving mechanism 4 further includes a vertical slider 21. A vertical groove is provided on the side of the support frame 5 to slidably engage with the vertical slider 21. The vertical slider 21 is fixedly mounted on the side of the sliding bracket 6. The paving mechanism 4 also includes a vertical lead screw 22, which is rotatably mounted within the vertical groove. The vertical slider 21 has a vertical threaded hole that threadedly engages with the vertical lead screw 22. The paving mechanism 4 further includes a second motor 23, which is fixedly connected to the support frame 5, and its output end is coaxially fixedly connected to the vertical lead screw 22.

[0039] When the second motor 23 drives the vertical lead screw 22 to rotate, the vertical slider 21 is driven to slide up and down in the vertical groove through the thread transmission, thereby causing the sliding bracket 6 to move vertically along the support frame 5, adjusting the distance between the bottom of the first rotating plate 7 and the second rotating plate 8 and the surface of the conveyor belt 2 to the preset paving thickness.

[0040] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
