Description

A sludge biomass energy fuel briquetting machine Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and in particular to a sludge biomass energy fuel briquetting machine. Background Technology

[0002] Sludge from domestic sewage is relatively rich in organic matter and tends to be plastic under suitable moisture conditions. Due to the special colloidal properties, fibrous structure, and stickiness of organic matter, it intertwines and entangles with each other, giving the sludge good plasticity. When making biomass fuel from plastic sludge, biomass additives need to be added during the pretreatment process to improve its performance. Common additives include sawdust, straw, and rice husks, which can increase the calorific value of the fuel. Afterward, a briquetting machine can be used to briquette the treated sludge to make biomass energy fuel.

[0003] Patent CN222407343U discloses a sludge recycling and briquetting device. This device uses a screw to rotate, causing a U-shaped support to move upwards, which in turn moves a briquetting limiting frame upwards. The sludge blocks inside the limiting frame are discharged under gravity, automatically completing the discharge process with high efficiency. However, this device requires manual placement of the sludge into the molding die. During manual placement, the sludge collides with the die under gravity, easily splashing out and contaminating the briquetting machine's table, surrounding floor, and other equipment components, making subsequent cleaning difficult. Furthermore, manual placement makes it difficult to control the amount of sludge added each time, resulting in inconsistent size and quality of the sludge biomass fuel produced by the briquetting machine.

[0004] In view of this, the present invention proposes a sludge biomass energy fuel briquetting machine. Summary of the Invention

[0005] The technical implementation scheme of this utility model is as follows: a sludge biomass energy fuel briquetting machine includes a workbench, a support plate fixedly connected to the upper surface of the workbench, a cylinder fixedly connected to the support plate, a pressure plate fixedly connected to the telescopic end of the cylinder, a storage box provided on the lower surface of the workbench, a conveying pipe rotatably connected to the workbench, a mold frame fixedly connected to the upper surface of the workbench, a cover plate fixedly connected to the end of the conveying pipe near the mold frame, a collar sleeved on the outer surface of the conveying pipe, a spiral conveying rod rotatably connected to the inner cavity of the conveying pipe, the upper end of the spiral conveying rod passing through the conveying pipe and fixedly connected to the output end of a motor, the motor being fixedly mounted on the conveying pipe, a diagonal rod fixedly connected to the telescopic end of the cylinder, a sliding rod fixedly connected to the end of the diagonal rod near the conveying pipe, a guide groove opened on the outer surface of the conveying pipe, the sliding rod passing through the inner side of the collar and slidingly connected to the guide groove, the bottom ends of the conveying pipe and the spiral conveying rod both passing through the storage box, and a feeding assembly for removing sludge briquettes is also provided on the workbench.

[0006] Preferably, the unloading assembly includes an L-shaped plate fixedly connected to the bottom of the workbench, a threaded rod rotatably connected to the L-shaped plate, a second motor fixedly installed at the bottom of the L-shaped plate, the output end of the second motor fixedly connected to the threaded rod, the end of the threaded rod away from the L-shaped plate rotatably connected to the workbench, a threaded sleeve plate threadedly connected to the outer surface of the threaded rod, a base plate fixedly connected to the threaded sleeve plate, a through hole adapted to the base plate being opened on the workbench, a cylindrical rod fixedly connected to the bottom of the workbench, and the threaded sleeve plate slidingly connected to the cylindrical rod.

[0007] Preferably, filter holes are symmetrically opened on the bottom plate, and filter gauze is fixedly connected to the upper surface of the bottom plate.

[0008] Preferably, the end of the threaded rod away from the L-shaped plate extends out of the upper surface of the worktable and is fixedly connected to a disc. A movable shaft is fixedly connected to the disc, and a sliding frame is slidably connected to the outer surface of the movable shaft. A rectangular frame is fixedly connected to the side of the sliding frame near the mold frame, and the rectangular frame is slidably connected to the worktable.

[0009] Preferably, a rectangular frame is fitted onto the outer wall of the mold frame, and multiple rubber impact balls are symmetrically fixedly connected to the inner side wall of the rectangular frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] By using the cover plate to shield the workpiece and forming a seal with the mold frame and the base plate, it is possible to effectively prevent the sludge from colliding with the mold frame and splashing onto the outside and the workbench when sludge is poured in, thus avoiding sludge contamination of the workbench surface and reducing the need for manual cleaning.

[0012] By rotating the screw conveyor to transport sludge, the consistency of sludge briquetting can be improved. By transporting a fixed amount of sludge each time, and in conjunction with the specifications of the mold, the size and shape of the briquetting blocks can be effectively guaranteed to be basically consistent. Sludge blocks with uniform shape and specifications are easy to store, transport, and subsequently put into combustion equipment.

[0013] Because the cover plate is attached to the upper surface of the mold frame, the mold frame will scrape off the mud adhering to the cover plate, preventing the mud from splashing and adhering to the cover plate when it is conveyed into the mold frame. In addition, before the cylinder drives the pressure plate to perform the briquetting operation, the feed pipe and the cover plate can be automatically moved away, so as not to block the pressure plate, thus improving the efficiency of the briquetting machine.

[0014] When the cylinder drives the pressure plate to descend and squeeze the sludge, the water mixed in the sludge will be filtered through the filter cloth and flow out through the filter holes on the bottom plate. This prevents the residual water in the sludge from being unable to drain and prolonging the heating and drying time, thereby speeding up the drying and shaping of the sludge. In addition, the staff can place an external container on the ground below the filter holes, and the water flowing out of the filter holes can be collected by the external container for easy cleaning.

[0015] The two rows of rubber impact balls inside the rectangular frame contact and adhere to the outer surface of the mold frame in turn. When the mold frame is impacted, it will vibrate, which is more conducive to the sludge block detaching from the inner wall of the mold frame, thus achieving smooth demolding and avoiding the situation where the sludge block after pressing sticks to the inner wall of the mold frame and cannot be demolded smoothly.

A feeding assembly for removing sludge blocks is also provided on the workbench 1.

[0026] As shown in Figures 3 to 5, the feeding assembly includes an L-shaped plate 13 fixedly connected to the bottom of the workbench 1. A threaded rod 14 is rotatably connected to the L-shaped plate 13. A second motor is fixedly installed at the bottom of the L-shaped plate 13. The output end of the second motor is fixedly connected to the threaded rod 14. The end of the threaded rod 14 away from the L-shaped plate 13 is rotatably connected to the workbench 1. A threaded sleeve 15 is threadedly connected to the outer surface of the threaded rod 14. A cylindrical rod is fixedly connected to the bottom of the workbench 1. The end of the threaded sleeve 15 away from the threaded rod 14 is vertically slidably connected to the cylindrical rod to limit the threaded sleeve 15 to move only vertically. A base plate 16 is fixedly connected to the threaded sleeve 15. A through hole adapted to the base plate 16 is opened on the workbench 1. The base plate 16 can be embedded into the through hole of the workbench 1. A filter hole is opened on the base plate 16. A filter gauze is fixedly connected to the upper surface of the base plate 16.

[0027] As shown in Figures 4 and 5, the end of the threaded rod 14 away from the L-shaped plate 13 extends out of the upper surface of the workbench 1 and is fixedly connected to a disc 17. A movable shaft 18 is fixedly connected to the disc 17. The axis of the movable shaft 18 is not collinear with the axis of the threaded rod 14. A sliding frame 19 is slidably connected to the outer surface of the movable shaft 18. A rectangular frame 20 is fixedly connected to the side of the sliding frame 19 near the mold frame 7. The rectangular frame 20 is fitted onto the outer wall of the mold frame 7 and is slidably connected to the upper surface of the workbench 1. Multiple rubber impact balls 21 are symmetrically fixedly connected to the inner side wall of the rectangular frame 20.

[0028] The working process of the above embodiments:

[0029] Initial state: The cover plate 6 is in contact with the upper surface of the mold frame 7, the bottom plate 16 is in the highest state and fits with the through hole in the workbench 1, and multiple rubber impact balls 21 on one side of the inner wall of the rectangular frame 20 are in contact with the outer surface of the mold frame 7.

[0030] In use, the pre-treated sludge is first poured into the storage bin 4. Then, the motor is started to make the screw conveyor 9 rotate. The screw blades work together to transport the sludge inside the storage bin 4 to the upper part of the conveying pipe 5 and gradually to the end near the cover plate 6. The sludge then falls into the mold frame 7 through the holes in the cover plate 6. At this time, the sludge is located above the bottom plate 16. The cover plate 6 blocks the sludge, and the mold frame 7 and the bottom plate 16 form a seal. This effectively prevents the sludge from colliding with the mold frame 7 and splashing onto the outside and the workbench 1 when it is poured in, thus avoiding sludge contamination of the workbench 1 and reducing the need for manual cleaning.

[0031] It should be noted that the start time of the motor can be controlled by the controller to effectively control the time of sludge conveying by the screw conveyor 9 each time, so that the amount of sludge conveyed into the mold frame 7 is consistent each time. This avoids the situation where the amount of sludge is not consistent each time when it is manually put into the mold frame 7. The sludge conveying by the screw conveyor 9 can improve the consistency of sludge briquette forming. The fixed amount of sludge conveyed each time, combined with the specifications of the mold, can effectively ensure that the size and shape of the briquette are basically consistent. Sludge briquettes with uniform shape and specifications are easy to store, transport and put into combustion equipment.

[0032] After the sludge conveying is completed, cylinder 3 starts, causing the pressure plate at its telescopic end to move downwards. Simultaneously, it also causes the inclined rod 10 and sliding rod 11 to move downwards. As sliding rod 11 moves downwards, it moves within the guide groove 12, causing the collar 8 to slide downwards on the outer wall of the conveying pipe 5. Sliding rod 11 then presses against the inclined groove of the guide groove 12, causing the conveying pipe 5 to rotate. The conveying pipe 5 also causes the cover plate 6 to rotate synchronously and gradually stop obstructing the upper surface of the mold frame 7. At this point, sliding rod 11 moves into the vertical groove of the guide groove 12 and no longer causes the conveying pipe 5 to rotate. The conveying pipe 5 remains stationary. At this time, cylinder 3... The cylinder 3 continuously lowers the pressure plate and contacts the sludge inside the mold frame 7, squeezing and pressing the sludge into blocks. At the same time, the heating wire inside the mold frame 7 can be activated to heat and dry the sludge, accelerating the sludge block forming. When the cover plate 6 rotates with the conveying pipe 5, the mold frame 7 will scrape off the sludge adhering to the cover plate 6 because the cover plate 6 is in contact with the upper surface of the mold frame 7, preventing the sludge from splashing and adhering to the cover plate 6 when it is conveyed into the mold frame 7. Before the cylinder 3 drives the pressure plate to perform the block forming operation, the conveying pipe 5 and the cover plate 6 can be automatically moved away, so as not to block the pressure plate, thus improving the efficiency of the block forming operation of the block forming machine.

[0033] Furthermore, when the cylinder 3 drives the pressure plate to descend and squeeze the sludge, the water mixed in the sludge will be filtered through the filter gauze and flow out through the filter holes on the bottom plate 16, which will speed up the drying and shaping of the sludge. Moreover, the staff can place an external container on the ground below the filter holes, and the water flowing out of the filter holes can be collected by the external container for easy cleaning.

[0034] Furthermore, after the sludge briquette is formed, the second motor is started, and the threaded rod 14 rotates, causing the threaded sleeve 15 connected to it to descend. The threaded sleeve 15 causes the base plate 16 to move downward, thereby causing the sludge briquette formed on the base plate 16 to move downward. When the threaded rod 14 rotates, it also causes the disk 17 fixed on it to rotate. The disk 17 causes the movable shaft 18 to rotate. During the rotation of the movable shaft 18, it also slides in the sliding frame 19 and pushes the sliding frame 19 and the rectangular frame 20 to move horizontally on the upper surface of the worktable 1. As the threaded rod 14 continues to rotate, it can drive the rectangular frame 20 to move back and forth, so that the two rows of rubber impact balls 21 on the inner side of the rectangular frame 20 successively come into contact with and adhere to the outer surface of the mold frame 7. When the mold frame 7 is impacted, it will vibrate, which is more conducive to the sludge briquette detaching from the inner wall of the mold frame 7, thereby achieving smooth demolding and avoiding the situation where the sludge briquette after briquetting adheres to the inner wall of the mold frame 7 and cannot be demolded smoothly.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
