Description

Technical Field

[0001] This application relates to the field of sludge co-firing technology, and more specifically, to a vibrating sludge cutter and a sludge co-firing and conveying system. Background Technology

[0002] In a direct sludge blending system, the sludge conveying equipment can stably transport semi-dry sludge (moisture content 20%–60%). The blending effect of peat is affected by the viscosity of the semi-dry sludge. For example, as the moisture content increases or the sludge ferments, the viscosity of the semi-dry sludge will increase abnormally, causing it to be stirred into large lumps. These lumps fall onto the coal conveyor belt, affecting conveying and screening. After being transported into the coal crusher, they easily clog the crusher's screen plate, causing an abnormal increase in operating load until overload shutdown, seriously threatening the stable operation of peat blending.

[0003] To alleviate the high load on the coal crusher, the sludge conveying equipment can be stopped or the conveying rate reduced. Once the coal crusher load returns to normal, the sludge conveying equipment can be restarted or the conveying rate increased. However, this method not only reduces the quantity and efficiency of sludge co-firing, but also requires constant monitoring of the semi-dry sludge's condition and the coal crusher's operating load, as well as continuous adjustments to the semi-dry sludge conveying rate. This increases the workload of operators and negatively impacts the stable operation of the sludge co-firing system, thus posing a potential safety hazard.

[0004] Therefore, a vibratory slurry cutter and a peat blending and conveying system are needed to solve the above problems. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0034] Figure 1 This is a schematic diagram of the vibratory mud cutter used in a specific embodiment of this application. Figure 2 for Figure 1 A schematic diagram of the main body of the sludge cutter is shown. Figures 1 to 2 As shown, the vibratory mud cutter includes a connecting spring 2, a mud cutter body 3, and a support frame 1.

[0035] The vibratory sludge cutter includes: multiple connecting springs 2, a sludge cutter body 3, and a support frame 1; the sludge cutter body 3 is used to cut sludge as it passes through; the multiple connecting springs 2 are evenly distributed along the circumferential direction on the support frame 1, and the sludge cutter body 3 is suspended in the support frame 1 by the connecting springs 2 and can support reciprocating movement within the frame 1.

[0036] The support frame 1 is typically fixed in a designated position. The support frame 1 has a cavity for the installation and movement of the sludge cutter body 3. Multiple connecting springs 2 are evenly distributed circumferentially around the sludge cutter body 3 and the support frame 1. Each connecting spring 2 is inclined under the weight of the discharge cylinder 31 and the sludge. The sludge cutter body 3 is suspended within the cavity by the connecting springs 2, located at the center of the support frame 1 and relatively above it. The connecting springs 2 allow the sludge cutter body 3 to have freedom of movement, enabling it to vibrate vertically and sway horizontally. When sludge passes through the sludge cutter body 3, it contacts the cutter body as it falls and is cut by it. Simultaneously, the sludge exerts an additional force on the connecting springs 2 as it passes through the sludge cutter body 3. During the extension and contraction of the springs, the sludge cutter body 3 vibrates and moves, thereby accelerating the cutting of the sludge.

[0037] The aforementioned vibratory sludge cutter, by changing the size of the sludge in the cutter body 3, and the connecting spring 2 intensifies the vibration and movement of the cutter body 3, effectively cutting large sludge pieces into smaller ones. This solves the problem of abnormally increased viscosity of semi-dry sludge caused by fermentation or increased moisture content, leading to the mixing of semi-dry sludge into large lumps, clogging the screen plate of the coal crusher, and causing a shutdown. It reduces the operating load of the coal crusher, ensuring stable operation during sludge co-firing and maximizing the amount of sludge co-firing. Simultaneously, it reduces the labor intensity of operators monitoring the process and the workload of maintenance personnel cleaning the sludge. Furthermore, the equipment is simple to operate and maintain, has a low failure rate, and is highly reliable.

[0038] In one embodiment of this application, the support frame 1 includes support columns 11, support beams 12, and support plates 13. Multiple support columns 11 are evenly distributed in the circumferential direction, such as four columns forming a square, or eight columns forming a circle or approximately a circle. Adjacent support columns 11 are connected by at least one support beam 12. The bottom end of the support column 11 is provided with a support plate 13, which can increase the contact area of ​​the support column 11. The support column 11 can be fixed to the ground or a designated position by the support plate 13, for example, by fixing it to the ground with expansion bolts, or by welding it to the support leg of the coal conveyor.

[0039] Optionally, the sludge cutter body 3 includes a discharge cylinder 31, at least one cutting unit, and a drive mechanism. The discharge cylinder 31 is connected to the support frame 1 via connecting springs 2. The cutting unit is connected to the discharge cylinder 31 and is positioned on the discharge path of the discharge cylinder 31. The drive mechanism is connected to the discharge cylinder 31 and can drive the discharge cylinder 31 to reciprocate. Multiple connecting springs 2 are evenly distributed in the circumferential direction of the discharge cylinder 31. One end of the connecting spring 2 is connected to the top or near the top of the support column, and the other end of the connecting spring 2 is connected to the top or near the top of the discharge cylinder 31. The discharge cylinder 31 has a hollow structure, and the cutting unit is located inside the hollow structure. Depending on the cutting size requirements, one or multiple cutting units can be arranged at intervals along the height direction of the discharge cylinder 31. Large pieces of sludge enter from the top of the discharge cylinder 31 and exit from the bottom. When passing through the cutting unit, the large pieces of sludge are cut into smaller pieces of sludge. The drive mechanism drives the discharge cylinder 31 to vibrate, accelerating the speed at which the sludge passes through the cutting unit, thus helping to achieve accelerated cutting. The cutter body described above has a sophisticated structure and produces excellent cutting results.

[0040] In one embodiment of this application, the driving mechanism includes, but is not limited to, a vibration motor 33. The vibration motors 33 are typically arranged in pairs and opposite each other. One vibration motor 33 is arranged on each of the left and right sides of the feeding cylinder 31, and they are symmetrically arranged. The two vibration motors 33 start and stop synchronously. When the vibration motors 33 are running, they generate vibration in the vertical direction, and the vibration in the horizontal direction is mutually canceled out.

[0041] Figure 3 for Figure 2 A schematic diagram of the upper cutting unit of the main body of the mud cutter. Figure 4 for Figure 2 A schematic diagram of the lower cutting unit of the main body of the sludge cutter is shown. Figure 3 and Figure 4 As shown, the material discharge cylinder 31 is equipped with cutting units at both ends, and the cutting wire mesh of the cutting units extends in different directions.

[0042] Optionally, the cutting unit includes at least one layer of cutting wire mesh passing through the discharge cylinder 31, with each layer of cutting wire mesh evenly distributed in the radial direction of the discharge cylinder 31. When the sludge passes through the cutting unit, the taut cutting wire mesh effectively segments the sludge. The cutting wire mesh provides an effective cutting plane, cutting the passage space of the discharge cylinder 31 into strips or a mesh shape, thereby cutting the sludge into strips or blocks. The cutting wire mesh provides a high cutting speed and ensures smooth operation. Moreover, the cutting wire mesh only changes the shape of the sludge, without altering its properties.

[0043] To prevent the cutting wire 35 from damaging the through holes and the feed cylinder 31 during vibration, thus further affecting the normal operation of the cutting wire 35, the feed cylinder 31 may optionally be provided with multiple through holes evenly distributed along the circumferential direction. A wire guard ring 36 is installed inside each through hole, and the cutting wire 35 of the cutting wire mesh passes through the wire guard ring 36. The wire guard ring 36 can protect the integrity of the feed cylinder 31 while ensuring the tension of the cutting wire mesh.

[0044] In one embodiment of this application, to ensure the structural strength of the material discharge cylinder 31, a reinforcing frame 32 can be added. Cutting wires 35 are installed inside the reinforcing frame 32. The material discharge cylinder 31 has few or no through holes, while symmetrical through holes are made on the reinforcing frame 32. The cutting wires 35 pass through these through holes one by one to form a cutting wire mesh. Then, the reinforcing frame 32 is installed on the material discharge cylinder 31. By setting the reinforcing frame 32, damage to the material discharge cylinder 31 by the cutting wires 35 can be avoided, ensuring the integrity of the material discharge cylinder 31, while also preventing any impact on structural strength.

[0045] To facilitate installation and disassembly and reduce the difficulty of assembly and replacement, in one embodiment of this application, the wire guard ring 36 is nested in the through hole through its outer surface, the central hole of the wire guard ring 36 has a smooth surface, and the cutting line 35 passes through the central hole of the wire guard ring 36.

[0046] In order to extend service life, reduce damage and reduce maintenance rate, the wire guard ring 36 has sufficient strength and wear resistance to avoid being cut by the cutting wire 35; in one embodiment of this application, the wire guard ring 36 is made of at least one of rubber, metal, plastic or ceramic materials.

[0047] The cutting wire 35 should have sufficiently high strength and can be made of metal or non-metal materials. In one embodiment of this application, the metal cutting wire 35 includes, but is not limited to, copper wire, steel wire, iron wire, etc., and the non-metal cutting wire 35 includes, but is not limited to, nylon wire, ultra-high molecular weight polyethylene wire, polyaryletherketone wire, polyester fiber wire, etc.

[0048] Typically, the cutting lines 35 of each layer of the cutting unit extend in the same direction. Depending on the cutting requirements, the size of the sludge can be controlled by adjusting the extension direction of the cutting lines 35 of different layers. Optionally, there are multiple cutting units, which are distributed relative to each other and spaced apart along the axial direction of the discharge cylinder 31; the extension directions of the cutting lines 35 of adjacent cutting units are intersecting.

[0049] According to on-site requirements, the spacing between the cutting lines 35 and the height difference between the upper and lower layers of the cutting mesh are adjusted. In one embodiment of this application, there are two cutting units. The cutting lines 35 of the upper layer of the cutting mesh extend inward and outward, while the cutting lines 35 of the lower layer extend inward and outward. Large pieces of sludge are cut into long strips by the upper layer of the cutting mesh, and the long strips of sludge are cut into small squares by the lower layer of the cutting mesh.

[0050] In one embodiment of this application, the cutting lines 35 in the cutting wire mesh are arranged in parallel. The distance between the cutting lines 35 can be equal or unequal. Typically, the distance between the cutting lines 35 is the same and relatively large, for example, 100mm. The distance between the reinforcing frame 32 and the cutting lines 35 is reduced, for example, 50mm.

[0051] Furthermore, when there are multiple cutting units, the size of the sludge can be further controlled by adjusting the spacing of the cutting lines 35 in different layers, either simultaneously or individually. For example, the spacing of the cutting lines 35 is larger for cutting units closer to the feed and smaller for cutting units farther from the feed, so that the size of the sludge gradually decreases as it passes through the cutting units one by one. Large pieces of sludge are cut into long strips by the cutting wire mesh of the previous layer, and the long strips of sludge are cut into thin strips by the cutting wire mesh of the next layer.

[0052] To ensure the sharpness of the cutting wire 35, it can be replaced manually or automatically periodically. Optionally, the main body 3 of the cutter also includes a wire release wheel 341 and a wire take-up wheel 342. The wire release wheel 341 and the wire take-up wheel 342 are respectively arranged on opposite sides of the cutting unit and are used to release and collect the cutting wire. The cutting wire 35 includes a head end and a tail end arranged opposite each other. The tail end is fixed on the wire release wheel 341, and the head end passes through the feed cylinder 31 to form a cutting wire net and is then fixed to the wire take-up wheel 342. The wire release wheel 341 and the wire take-up wheel 342 can adopt the same or similar structure. Unused cutting wire 35 is wound on the wire release wheel 341, and the cutting wire 35 after the cutting operation is collected by the wire take-up wheel 342.

[0053] The lead-out reel 341 and take-up reel 342 can be manually or mechanically driven. In one embodiment of this application, a rotating handle is installed on the lead-out reel 341 and take-up reel 342. By driving the rotating handle, the lead-out reel 341 can release the cut wire 35, and the take-up reel 342 can collect the cut wire 35. At the same time, a locking unit is installed on the lead-out reel 341 and take-up reel 342. When the locking unit is unlocked, the lead-out reel 341 and take-up reel 342 can rotate. When the locking unit is locked, the lead-out reel 341 and take-up reel 342 remain relatively stationary.

[0054] In one embodiment of this application, a drive motor is installed on the outgoing wire holding wheel 341 and the taking-up wire holding wheel 342. The drive motor drives the outgoing wire holding wheel 341 and the taking-up wire holding wheel 342 to rotate. The holding wheel releases the cutting wire 35, and the taking-up wire holding wheel 342 collects the cutting wire 35.

[0055] The cutting wire mesh composed of cutting wires 35 is usually in a relatively taut state. After a period of vibration, the area where the cutting wires 35 are in frequent contact with the sludge may become relatively weak or loose. To ensure that the cutting wires 35 are in a relatively taut state and provide better cutting results, the sludge cutter body 3 may optionally include: pulleys 39; at least one pulley 39 is provided between the wire outlet fixing wheel 341 and the cutting wire mesh; and / or at least one pulley 39 is provided between the wire take-up fixing wheel 342 and the cutting wire mesh. The pulleys 39 are fixed on the discharge cylinder 31. The pulleys can change the direction of the cutting wires 35 and keep the cutting wires 35 relatively taut. Moreover, in order to improve the cleanliness of the cutting wires 35, the sludge-adhered cutting wires 35 can be effectively peeled off and removed when passing through multiple pulleys 39 and bending in different directions, ensuring that the cutting wires 35 are effectively collected into the wire take-up fixing wheel 342.

[0056] In one embodiment of this application, four pulleys 39 are provided between the take-up and holding reel 342 and the cutting wire mesh, wherein the two pulleys 39 at both ends are positioned to the right, and the two middle pulleys 39 are positioned to the left. The cutting wire 35 passes around the right side of the lower pulley 39, the left side of the two middle pulleys 39, and the right side of the upper pulley 39. Four pulleys 39 are also provided between the take-up and holding reel 342 and the cutting wire mesh, arranged in a mirror-symmetric manner as described above.

[0057] At least one pulley 39 is provided between the upper and lower cutting wire meshes. In one embodiment of this application, a pulley 39 is provided between the upper and lower cutting wire meshes, and the outgoing wire of the upper cutting wire mesh passes around the right side of the pulley 39 as the incoming wire and enters the lower cutting wire mesh.

[0058] Cutting wire meshes of the same or different layers are usually made using the same cutting wire 35. When cutting wires 35 are laid in adjacent layers, the direction of the cutting wires 35 may need to be changed, such as from horizontal extension to vertical extension, or from one side to an adjacent side. In order to guide the change of the cutting wires 35 and avoid damage to the discharge cylinder 31 during the movement of the cutting wires 35, the main body 3 of the cutter optionally includes a guide tube 37. The guide tube 37 is sleeved outside the cutting wires 35, connected to the discharge cylinder 31, and used to guide the change of direction of the cutting wires 35 between adjacent cutting wire meshes. The guide tube 37 is usually a bent tube. The bent tube is installed at the position where the direction of the cutting wires 35 needs to be changed. The bent tube can be installed on the discharge cylinder 31 or on the reinforcing frame 32, such as by welding or screw fixing. The cutting wires 35 are laid through the bent tube, and the space provided by the bent tube allows the cutting wires 35 to adjust their extension direction. The guide tube 37 is used to guide the assembly of the cutting line 35 and protect the material drop cylinder 31, preventing the material drop cylinder 31 from being damaged when the cutting line 35 moves or cuts.

[0059] Optionally, the sludge cutter body 3 further includes: a cleaning cone 38, which is sleeved around the cutting wire 35, and at least one cleaning cone 38 is disposed between the take-up reel 342 and the cutting wire mesh; and / or at least one cleaning cone 38 is disposed between the take-out reel 341 and the cutting wire mesh. The smaller diameter end of the cleaning cone 38 faces the cutting wire mesh, and the larger diameter end faces the take-up reel 342. When sludge accumulated on the cutting wire 35 needs to be collected, the cutting wire 35 first passes through the cleaning cone 38. Because the diameter of the cleaning cone 38 is small, the sludge on the cutting wire 35 is scraped off by the cleaning cone 38 when it passes through, thereby ensuring that the cutting wire 35 collected by the take-up reel 342 is relatively clean. The smaller diameter end of the cleaning cone 38 faces the cutting wire mesh, and the larger diameter end faces the wire release wheel 341. There may be clumps or sludge on the cutting wire 35. The cutting wire 35 passes through the cleaning cone 38. Because the diameter of the cleaning cone 38 is small, the clumps or sludge cannot pass through, thus ensuring that the cutting wire 35 released by the wire release wheel 341 is relatively clean.

[0060] To ensure effective cable delivery and take-up, and to guarantee cutting results, the cable guard rings 36 within the same cutting unit have the same height, and the cable guard rings 36 on opposite sides of the cutting unit are symmetrically arranged. The cable routing directions on both sides of the same pulley 39 are perpendicular to each other. The cable routing on the pulleys 39 at both ends, as well as the cable routing on the cable delivery wheel 341 / cable take-up wheel 342, should be kept as vertical as possible.

[0061] The following section further describes the usage process of the vibratory mud cutter.

[0062] The support frame 1 is fixed in a designated position, and the discharge cylinder 31 is installed into the cavity of the support frame 1 via a connecting spring 2. The discharge cylinder 31 can sway and vibrate within this cavity. When sludge passes through the discharge cylinder 31, the vibration motor 33 drives the discharge cylinder 31 to vibrate. When the sludge falls, it contacts the cutting line 35 and is cut by the cutting line 35. At the same time, during the movement and cutting of the sludge, an additional force is generated on the connecting spring 2. During the extension and contraction of the spring, the discharge cylinder 31 is pulled to vibrate and move, thereby accelerating the cutting of the sludge. When the cutting speed of the cutting line 35 decreases due to sludge retention, the output wire fixing wheel 341 and the take-up wire fixing wheel 342 are driven to operate. While collecting the old cutting line 35, new cutting lines 35 are released, replacing the cutting lines 35 in the discharge cylinder 31. When the old cutting line 35 passes through the cleaning cone 38 and the pulley 39, the sludge is effectively peeled off, so that the cutting line 35 collected by the take-up wire fixing wheel 342 is effectively cleaned for subsequent use.

[0063] This application also provides a peat blending and conveying system, including: a vibrating sludge cutter, a sludge conveyor, a scraper conveyor, a coal conveyor, a screening machine, and a coal crusher.

[0064] The peat co-firing and conveying system includes the vibratory sludge cutter described above; the vibratory sludge cutter is capable of cutting the passing sludge. Any of the vibratory sludge cutters described above can be used, and will not be elaborated further here.

[0065] The sludge conveyor is positioned above the sludge cutter body 3 of the vibrating sludge cutter. The sludge conveyor is used to supply sludge to the sludge cutter body 3; typically, the moisture content of the sludge is maintained between 20% and 60%. The sludge conveyor supplies sludge to the sludge cutter body 3. The size of the sludge conveyor's discharge pipe is no larger than the size of the material discharge cylinder 31 of the sludge cutter body 3, and the outlet of the sludge conveyor's discharge pipe is located directly above the inlet of the material discharge cylinder 31, allowing the sludge supplied by the sludge conveyor to enter the material discharge cylinder 31. The sludge conveyor includes, but is not limited to, a single-spiral bidirectional shaftless conveyor.

[0066] The scraper conveyor is used to scrape off the sludge from the sludge conveyor. The sludge with high viscosity is stuck on the sludge conveyor, which affects the normal operation of the sludge conveyor. After being rolled and stirred by the scraper conveyor, the sludge is removed from the stuck position and can be transported into the discharge cylinder 31 by the sludge conveyor.

[0067] The coal conveyor is positioned below the main body 3 of the vibrating sludge cutter and is used to transport coal blocks and receive sludge cut by the main body 3 of the sludge cutter. The conveyor belt of the coal conveyor can cover the outlet of the discharge cylinder 31 of the main body 3 of the sludge cutter, and the conveyor belt of the coal conveyor is located directly below the outlet of the discharge cylinder 31. Small pieces of sludge cut by the discharge cylinder 31 fall onto the conveyor belt of the coal conveyor, and coal blocks are also transported on the conveyor belt, so that the coal blocks and small pieces of sludge are initially mixed.

[0068] The screening machine is used to separate coal lumps and sludge output from the coal conveyor. When the coal lumps and sludge provided by the coal conveyor pass through the screening machine, the coal lumps and sludge of suitable size can pass through the screening machine and enter the subsequent equipment. Coal lumps and sludge that are too large are screened out, crushed again manually or mechanically, and then fed back onto the coal conveyor for transportation. They then pass through the screening machine again until they are of suitable size before entering the subsequent equipment.

[0069] The coal crusher is used to receive and crush coal lumps and sludge output from the screening machine. Appropriately sized coal lumps and sludge should be fed into the crusher to prevent clogging of the screen plates, which could lead to abnormally high operating loads and even overload shutdown.

[0070] During assembly, the components arranged vertically from top to bottom are: a sludge conveyor, a vibrating sludge cutter, and a coal conveyor. Large sludge pieces fall from the sludge conveyor into the vibrating sludge cutter, where they are cut into smaller pieces that fall onto the coal conveyor. The sludge and coal are then transported by the coal conveyor to a screening machine. Suitable-sized coal and sludge pieces pass through the screening machine and enter the coal crusher. Oversized coal and sludge are screened out, then manually or mechanically crushed again before being fed back onto the coal conveyor for further transport, passing through the screening machine once more before entering the coal crusher.

[0071] As can be seen from the above description and practice, the vibratory sludge cutter and peat blending and conveying system provided in this application have the following advantages compared with the prior art: Using the aforementioned vibratory sludge cutter, the size of the sludge in the cutter body changes, and the connecting spring can intensify the vibration and movement of the cutter body, effectively cutting large pieces of sludge into smaller pieces. This solves the problem of abnormally increased viscosity of semi-dry sludge caused by fermentation or increased moisture content, leading to the semi-dry sludge being stirred into large pieces, causing blockage of the coal crusher screen and resulting in a shutdown. It reduces the operating load of the coal crusher, ensuring stable operation during sludge blending and maximizing the amount of sludge blended. It also reduces the labor intensity of operators monitoring the process and the workload of maintenance personnel cleaning the sludge. Furthermore, the equipment is simple to operate and maintain, has a low failure rate, and is highly reliable.

[0072] Those skilled in the art should understand that the above description is merely a specific embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the scope of this application should be included within the protection scope of this application.
