Description

Technical Field

[0001] The utility model relates to the field of sludge drying equipment, in particular to a sludge drying device. Background Art

[0002] Sludge is a solid waste generated during sewage treatment, mainly composed of organic matter, inorganic matter and water. Sludge contains rich nutrients, such as nitrogen, phosphorus, potassium, etc. After proper treatment, the dried sludge can be used as fertilizer to promote plant growth. In addition, the dried sludge can also be used as fuel for power generation or heating to achieve resource recycling. Therefore, the drying of sludge not only helps to reduce environmental pollution, but also realizes the recycling of resources, which has important economic and environmental benefits.

[0003] At present, sludge drying mainly uses heat exchange technology to reduce the moisture content of sludge. Existing medium and large sludge drying devices usually adopt a drum structure. The drum is placed at an angle, and the sludge enters the drum from the top feed port. During the rotation of the drum, the hot air at the bottom evaporates the water in the sludge through heat exchange, thereby achieving drying. This equipment can meet the needs of sludge drying to a certain extent, but there are some problems in actual use.

[0004] The main disadvantage of the existing sludge drying device is that it is easy to generate dust during its operation. Since the drum is tilted and rotates continuously, the dried sludge at the bottom will be broken up during the rolling process of the drum. The hot air input at the bottom will blow up the broken sludge particles, forming a large amount of dust. As the drum rotates, the dust is easy to escape from the feed port, causing environmental pollution and reducing the working efficiency of the equipment. In addition, the dust may also cause harm to the health of the operator. Utility Model Content

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Embodiment: A sludge drying device, such as Figure 1-Figure 5 As shown, it includes a support base 1, a mounting base 2, a conveyor belt 3, a first motor 31, a baffle 4, a support plate 5, a heating plate 6, a feed hopper 8, a heat preservation cover 9, a controller 10, an adjustment component, a base 16 and a storage box 17. The support base 1 is connected to the heat preservation cover 9, and the heat preservation cover 9 is connected to the mounting base 2. Rollers are arranged at both ends of the mounting base 2, and the conveyor belt 3 is wound on the rollers. A first motor 31 is installed on the side of the mounting base 2, and the first motor 31 passes through the heat preservation cover 9. The output shaft of the first motor 31 is connected to a roller for driving the conveyor belt 3. A support plate 5 is arranged in the middle of the mounting base 2, and the support plate 5 can support the conveyor belt 3, and a heating Plate 6, the heating plate 6 is used to heat the conveyor belt 3 and the sludge, the top of the front and rear sides of the mounting seat 2 are connected with baffles 4, the baffles 4 are used to prevent the sludge from overflowing from the two sides of the conveyor belt 3, and also to ensure that the flowing sludge covers the conveyor belt 3, a controller 10 is installed on the right side of the insulation cover 9, the controller 10 is wired to the heating plate 6 and the first motor 31, and the power of the heating plate 6 and the speed of the first motor 31 are controlled, a discharge port 7 is opened at the bottom left side of the insulation cover 9, and a feed hopper 8 is connected to the right end of the top of the insulation cover 9, a base 16 is arranged on the left side of the support seat 1, a storage box 17 is slidably connected to the base 16, and an adjustment component for adjusting the feed rate is arranged at the feed hopper 8.

[0025] like Figure 1 and Figure 4 As shown, the adjustment component includes an adjustment plate 11, a connecting shaft 12, a sleeve 13, an operating rod 14 and a fastening screw 15. The sleeve 13 is fixedly connected to the front side of the heat preservation cover 9, and the connecting shaft 12 is rotatably connected in the sleeve 13. The rear end of the connecting shaft 12 passes through the heat preservation cover 9 and is fixedly connected to the adjustment plate 11. The adjustment plate 11 is located at the bottom of the feed hopper 8. By rotating the adjustment plate 11, the angle between the adjustment plate 11 and the feed hopper 8 is changed, thereby changing the size of the opening at the bottom of the feed hopper 8 to control the flow rate of the sludge. The front end of the connecting shaft 12 is connected to the operating rod 14, and the sleeve 13 is threadedly connected to the fastening screw 15. The end of the fastening screw 15 is extruded and fitted with the connecting shaft 12 to limit the rotation of the connecting shaft 12.

[0026] The staff pours the collected sludge from the feed hopper 8 into the heat preservation cover 9, observes the flow rate of the sludge, and if the water content of the sludge is high, reduces the amount of sludge entering through the adjustment component, and controls the speed of the first motor 31 and the working power of the heating plate 6 through the controller 10;

[0027] After the sludge enters the feed hopper 8, the staff rotates the operating lever 14 according to the water content of the sludge. The operating lever 14 drives the adjusting plate 11 to rotate through the connecting shaft 12, thereby changing the size of the bottom opening of the feed hopper 8, and then changing the amount of sludge flowing into the heat preservation cover 9 per unit time. After the flow rate is appropriate, the fastening screw 15 is rotated, and the fastening screw 15 squeezes the connecting shaft 12 to limit its rotation, thereby fixing the angle of the adjusting plate 11. The sludge falls onto the conveyor belt 3 through the adjusting plate 11. While the first motor 31 drives the conveyor belt 3, it drives the sludge above to move to the left. The baffles 4 on both sides of the mounting seat 2 can limit the outflow of the sludge. When the sludge falls, part of the accumulated sludge is scraped flat by the adjusting plate 11, thereby effectively controlling the thickness of the sludge and making the conveyor belt 3 covered with sludge to ensure the drying efficiency.

[0028] As the sludge moves slowly, the heating plate 6 on the support plate 5 continuously dissipates heat, heats the conveyor belt 3 and the sludge thereon, and dries the moisture of the sludge. The dried sludge blocks fall into the storage box 17 from the discharge port 7. When the storage box 17 is full, it is pulled out to the left and replaced with an empty box to achieve continuous operation.

[0029] like Figure 1 and Figure 5 As shown, it also includes a fixed frame 18, a telescopic sleeve 19, a rotating shaft 20, a connecting rod 21, a pull rope 22 and a second motor 23. The fixed frame 18 is connected to the discharge port 7 of the heat preservation cover 9, and the telescopic sleeve 19 is connected to the bottom of the fixed frame 18. A lifting component for controlling the up and down movement of the telescopic sleeve 19 is arranged on the fixed frame 18. The fixed frame 18 is rotatably connected to the rotating shaft 20. A second motor 23 is installed on the front side of the fixed frame 18. The output shaft of the second motor 23 is connected to the rotating shaft 20. The connecting rod 21 is connected to the bottom of the telescopic sleeve 19. One end of the pull rope 22 is connected to the middle of the rotating shaft 20, and the other end is connected to the middle of the connecting rod 21. The rotating shaft 20 and the connecting rod 21 are both facing forward and backward, and the second motor 23 is connected to the controller 10 by wire.

[0030] When the silt blocks fall into the storage box 17, some debris flies out and hits the telescopic sleeve 19, so that the debris cannot leave the storage box 17. The staff adjusts the rotation rate of the second motor 23 according to the rotation rate of the first motor 31 through the controller 10. After the silt blocks fall into the storage box 17, they continue to accumulate. The second motor 23 drives the rotating shaft 20 to rotate, and the rotating shaft 20 is wound with the pull rope 22. The pull rope 22 pulls the bottom of the telescopic sleeve 19 through the connecting rod 21 to shrink it as a whole to avoid being buried by the silt blocks. At the same time, the blocking effect on the debris is guaranteed. After replacing the storage box 17, the second motor 23 is controlled to lower the pull rope 22 to reset the telescopic sleeve 19.

[0031] like Figure 1 As shown, an observation window 24 is also included. The front side of the heat preservation cover 9 is provided with an observation window 24.

[0032] like Figure 1 and Figure 5 As shown, a limit plate 25 is also included. The outer side of the base 16 is connected to the limit plate 25, and the limit plate 25 is located at the front, rear, and right side of the base 16.

[0033] like Figure 2 As shown, a scraper 26 is also included. The left end of the mounting seat 2 is connected to the scraper 26, and the scraper 26 is in contact with the surface of the conveyor belt 3.

[0034] like Figure 1 As shown, a cover plate 27 is also included, and a detachable cover plate 27 is arranged on the top of the feed hopper 8.

[0035] The staff monitors the sludge drying situation in real time through the observation window 24, and adjusts the rotation speed of the first motor 31 and the sludge feeding rate in time to ensure the drying effect. The limit plate 25 can limit the pushing position of the storage box 17 when the staff replaces it, so that the storage box 17 is aligned with the discharge port 7. The scraper 26 can remove the sludge blocks sticking on the conveyor belt 3 to ensure the surface quality of the conveyor belt 3. When the equipment is idle, the cover plate 27 covers the feed hopper 8 to reduce the entry of impurities or organisms and damage to the equipment.
