Description

Technical Field

[0001] The present invention relates to the technical field of water channel garbage treatment, and specifically to an assembled stirring device and its application in sludge drying of water channels. Background Technique

[0002] Drainage channels are important facilities for collecting sewage, plant area drainage, and storing and draining rainwater. Builders will plant trees on the slopes on both sides of the drainage channels for protection to prevent heavy rain from scouring the channel slopes, thereby protecting the drainage channels. However, when heavy rain falls, a small amount of soil will still be washed into the drainage channels. In addition, in autumn and winter, the leaves of the trees on the channel slopes begin to fall and fall into the drainage channels. After a long time, the fallen leaves rot, and the soil washed into the drainage channels and the fallen leaves form sludge, which will block the drainage channels. At this time, the staff will use existing equipment to pump the sludge out of the drainage channels and dry it. After drying, the dried sludge can be reused through different treatments. For example: 1. Through a series of procedures such as pre-screening, washing drums, and grading screens, the dredging sludge can be turned into building materials or construction sand, etc.; 2. Compost the sludge and organic waste together. After fermentation, the organic matter in the sludge is decomposed by microorganisms into fertilizers and made into nutrient soil.

[0003] Chinese Patent Application No. CN2019224972.X discloses a sludge drying device, including a cylindrical dryer body. The left end of the dryer body is higher than the right end, and the dryer body rotates along the axis of the dryer body. A material lifting device for driving the sludge is provided inside the dryer body. It includes a crushing device for crushing the sludge. The crushing device and the material lifting device are respectively arranged inside the left and right ends of the dryer body. The sludge moves from the left end of the dryer body to the right end of the dryer body. The present invention provides a sludge drying device with good sludge dewatering effect.

[0004] Chinese Patent Application No. CN201820295536.4 discloses a sludge drying chamber, belonging to the technical field of sludge treatment. The purpose of the present invention is to propose a sludge drying chamber. By setting a heat preservation layer, a heat reflection layer, and an electric heat conduction layer inside the drying chamber, heat loss is reduced, heat utilization rate is improved, and drying efficiency is increased. The present invention includes a drying chamber, a heat preservation layer, a heat reflection layer, and an electric heat conduction layer. A sludge feed port is provided on one side of the drying chamber, and a sludge discharge port is provided at the bottom of the drying chamber. Electric heat conduction layers are provided on the inner wall top plate and bottom plate of the drying chamber. A heat reflection layer is arranged outside the electric heat conduction layer, and a heat preservation layer is arranged outside the heat reflection layer.

[0005] The following problems will still occur when the above solutions are used: 1. The volume of the agitator is fixed, making it inconvenient to cooperate with drying equipment to build a drying system. Most of the structures of the agitator are pre-welded into shape, which is inconvenient for transportation and erection, and has poor mobility. Secondly, the material-lifting structure of the agitator is usually directly welded to the cylinder wall and cannot be removed. Once it is worn, the whole needs to be replaced, increasing the maintenance cost.

[0006] 2. When drying sludge through a heat source, too much sludge accumulation in the drying channel affects the drying efficiency. The sludge on the outside is more dry than that on the inside, and the drying is insufficient.

[0007] 3. The sludge in a semi-dry state will also form lumps, which will also affect the drying effect and the feeding of sludge. Summary of the Invention

Detailed implementation manners

[0024] The following further describes in detail the implementation manners of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0025] The feeding end of the barrel body 1 described in this application is to be connected to an external drying device and a feeding device. The drying device provides a hot air source for drying the sludge. The drying device and the feeding device are existing devices and will not be emphasized further.

[0026] Please refer to Figure 1 、 Figure 2 and Figure 3 , an assembled stirring device, including a barrel body 1. Two symmetrically arranged brackets 17 are fixed at the lower end of the barrel body 1. The right end of the barrel body 1 is provided with a feeding end. The drying device provides a dry hot air source, and the hot air is conveyed into the barrel body 1 to dry the sludge. An inspection door and an observation window are provided on the feeding end. When the internal components of the barrel body 1 are damaged, it can enter through the inspection door for maintenance. At the same time, when it is drying, the drying effect of the sludge can be directly observed through the observation window. The left end of the barrel body 1 is provided with a discharging end.

[0027] A base 14 and a bracket 17 are provided at the lower end of the cylinder 1. The feed end of the cylinder 1 is higher than the discharge end. Two sets of supporting wheels 15 are symmetrically provided at the upper end of the base 14. The supporting wheels 15 are rollingly connected to the cylinder 1. At the same time, the supporting wheels 15 support the cylinder 1. A motor 16 is installed at the upper end of the base 14. The output end of the motor 16 is transmission-connected to the cylinder 1 via a reducer, providing power for the rotation of the cylinder 1 and driving the cylinder 1 to rotate.

[0028] See also Figure 3 The cylinder body 1 has multiple cylinder cores that are coaxially disassembled and connected inside. The cylinder body 1 and the cylinder cores rotate synchronously, allowing the multiple cylinder cores to be freely assembled and installed in the cylinder body 1. This makes it more convenient to process each individual cylinder core, facilitate welding and production, and also facilitate flexible assembly and use.

[0029] See also Figure 4 , Figure 5 , Figure 6 The cylinder core includes two clamping rings 2 and a receiving ring 5. The clamping rings 2 and the receiving ring 5 are coaxially arranged. A plurality of detachable stirring baskets 7 and a plurality of stirring plates 4 are arranged between the two clamping rings 2. The stirring plates 4 and the stirring baskets 7 are staggered around the circumference of the clamping ring 2. By arranging the stirring plates 4 and the stirring baskets 7 at intervals, the stirring baskets 7 can hold more sludge than the stirring plates 4. When the cylinder body 1 rotates, the sludge inside the cylinder body 1 is lifted and falls in a regular pattern of more, less, more, less, so that the sludge rolls more evenly and the drying effect can be improved. At the same time, the detachable stirring baskets 7 and the plurality of stirring plates 4 are also arranged to facilitate the replacement of worn accessories and reduce maintenance costs.

[0030] Specifically, one side of the stirring plate 4 is folded, and the folding angle of the stirring plate 4 can be 90 degrees, 100 degrees, or 120 degrees. The folding edges of the multiple stirring plates 4 installed on the core are arranged in the same direction in a ring shape; By bending the stirring plate 4 at different bending angles, when the cylinder 1 rotates, the stirring plate 4 scoops up the sludge inside the cylinder 1 and brings the sludge to the top of the cylinder 1. Since the bending angles of the stirring plate 4 are different, the bending angle of the stirring plate 4 can be adjusted according to specific circumstances, and the timing of dumping the sludge is also different, so that the dumped sludge falls on the entire cross-section of the cylinder 1, so that the heat provided by the external dryer is maximized, heat waste is reduced, and the drying efficiency of the sludge is improved.

[0031] A plurality of fixing blocks 3 are fixedly connected to the outer side of the clamping ring 2 and are arranged at equal intervals along the circumferential direction thereof. A plurality of clamping grooves 21 are respectively formed at one end of the clamping ring 2 and are arranged at equal intervals along the circumferential direction thereof. Two clamping grooves 21 are arranged between every two adjacent fixing blocks 3. A plurality of U-shaped clamping blocks 51 are fixedly connected to the inner wall of the receiving ring 5 and are arranged at equal intervals along the circumferential direction thereof. These structures are various fittings on the clamping ring 2 or the receiving ring 5 and are mainly used for the assembly of the stirring plate 4 and the stirring basket 7; Specifically, both ends of each stirring plate 4 are respectively inserted into the clamping grooves 21 on the two clamping rings 2. Notches are respectively formed at the front and rear ends of the stirring plate 4. The stirring plate 4 is clamped with the clamping grooves 21 of the clamping ring 2 through the notches. With such a design, the stirring plate 4 can be easily disassembled, and when the stirring plate 4 is worn, it is convenient to replace the stirring plate 4; Please refer to Figure 5 , two double-headed screws 31 are installed on the stirring basket 7. Mounting holes are respectively formed on the fixing blocks 3 and the receiving ring 5 for inserting the double-headed screws 31; specifically, nuts are connected to the threaded portions of the double-headed screws 31 exposed outside the fixing blocks 3, and then the stirring basket 7 can be fixedly connected to the clamping ring 2 and the receiving ring 5. The two clamping rings 2 and one receiving ring 5 are fixedly combined into an independent core by the stirring basket 7 and the stirring plate 4. The receiving ring 5 is sleeved outside the stirring plate 4 and the stirring basket 7. The stirring plate 4 is clamped in the U-shaped clamping blocks 51, and the stirring basket 7 is clamped between two adjacent U-shaped clamping blocks 51. The receiving ring 5 is used to support and fix the stirring basket 7 and the stirring plate 4, ensuring that the stirring plate 4 has sufficient supporting force when stirring sludge and preventing the stirring plate 4 from deforming and being damaged.

[0032] Please refer to Figure 4 、 Figure 5 , bolts are respectively installed on the outer walls of the clamping rings 2. The bolts are threadedly connected to the clamping rings 2. By rotating the bolts, the bolts are pressed against the inner wall of the cylinder body 1, and the core is fixedly connected inside the cylinder body 1, so that the core rotates stably and synchronously with the cylinder body 1.

[0033] Further, please refer to Figure 3 、 Figure 5 and Figure 9, on the outer side of the clamping ring 2, inclined air guiding plates 8 are arranged between adjacent fixing blocks 3. The turning angles of the air guiding plates 8 on the two clamping rings 2 on the same core are the same, which is used to introduce hot air between the cylinder body 1 and the core. The hot air is introduced into the gap between the cylinder body 1 and the core through the air guiding plates 8, acting on the sludge from multiple surfaces, and can also quickly discharge the moisture generated inside the cylinder body 1, improving the drying efficiency. Specifically, the hot air source generated by the external drying equipment will directly enter the center of the core first through the feeding end of the cylinder body 1, similar to a through wind, passing through the entire cylinder body 1. At this time, due to the addition of the air guiding plates 8, a part of the hot air source will be guided into the space between the cylinder body 1 and the core. The heat acts on both sides of the sludge, increasing the heat exchange area of the sludge, thereby improving the drying efficiency of the sludge.

[0034] Further, please refer to Figure 8 , considering that the sludge may become caked, a plurality of blade plates 111 and a plurality of connecting rods 113 are equidistantly arranged along the circumferential direction on the inner wall of the feeding end of the cylinder body 1. The blade plates 111 are spiral. One end of the connecting rod 113 is hinged on the inner wall of the cylinder body 1, and the other end of the connecting rod 113 is fixedly connected with a knocking block 112. The plane where the swinging direction of the connecting rod 113 is located is parallel to the end face of the cylinder body 1. Designed in this way, when the cylinder body 1 rotates, the blade plates 111 will push the sludge, conveying the sludge into the cylinder body 1. At the same time, due to the change of gravity and center of gravity, the connecting rod 113 will swing with the rotation of the cylinder body 1, and the knocking block 112 on the connecting rod 113 will continuously knock the caked sludge block, increasing the heat receiving area of the sludge and improving the drying effect. At the same time, when the knocking block 112 falls and knocks, vibration will also be generated, which can shake off the sludge adhered to the cylinder body 1, facilitating material transmission, avoiding sludge accumulation and blockage at the feeding port, and also improving the drying effect of the sludge inside the cylinder body 1.

[0035] Example 1: Please refer to Figure 4 , only one end of the above clamping ring 2 is provided with a plurality of clamping grooves 21, which means that each assembled core is independent, and multiple independent cores cannot be spliced. Each core is separately fixed inside the cylinder body 1, with strong flexibility.

[0036] Example 2: Please refer to Figure 9 , compared with Example 1, both ends of the clamping ring 2 in Example 2 are provided with a plurality of clamping grooves 21 arranged equidistantly along the circumferential direction. The clamping grooves 21 at the left and right ends are staggered. Designed in this way, two independent cores can be combined together, and one clamping ring 2 can be saved, reducing the production cost. Moreover, multiple cores can be more firmly placed inside the cylinder body 1 by using this connection method.

[0037] Example 3: Please refer to Figure 5 , both ends of each stirring basket 7 are fixedly connected to the fixing blocks 3 on two clamping rings 2 respectively. The stirring basket 7 is fixedly connected between the fixing blocks 3 on two clamping rings 2 through a double-headed screw 31. The receiving ring 5 is sleeved at the waist line outside the stirring basket 7. Such a design makes the stirring basket 7 an integral long strip-shaped square box. Both ends of each stirring basket 7 are respectively butted against two clamping rings 2, which facilitates the installation operation. However, the length of the stirring basket 7 is relatively long, which is slightly inconvenient in production and transportation.

[0038] Embodiment 4: The stirring basket 7 is installed between the clamping ring 2 and the receiving ring 5. The stirring basket 7 is fixedly connected between the fixing block 3 and the receiving ring 5 through a double-headed screw 31. One end of the stirring basket 7 is provided with a stepped lap. The receiving ring 5 presses on the lap of the stirring basket 7, so that the double-headed screw 31 can still pass through the connection holes on the fixing block 3 and the receiving ring 5 to connect two stirring baskets 7 in series. Such a design divides the stirring basket 7 into two parts, shortens the length of the stirring basket 7, and is convenient for manufacturing.

[0039] The split design concept endows the stirring device with excellent scene adaptability and production efficiency. The innovation in the production and manufacturing link is particularly remarkable. The split structure enables each component to be processed and produced in parallel, improving the efficiency compared with the traditional integral welding manufacturing. The split design makes the overall size of the core barrel smaller and more convenient for production and transportation.

[0040] According to the above embodiments, different forms of core barrels can be spliced in this application; The first one; please refer to Figure 5 、 Figure 10 , and use the clamping ring 2 in Embodiment 1 and the stirring basket 7 in Embodiment 3.

[0041] The second one, please refer to Figure 7 , and use the clamping ring 2 in Embodiment 1 and the stirring basket 7 in Embodiment 4.

[0042] The third one, please refer to Figure 9 、 Figure 11 , and use the clamping ring 2 in Embodiment 2 and the stirring basket 7 in Embodiment 3.

[0043] The fourth one, not shown in the figure, uses the clamping ring 2 in Embodiment 2 and the stirring basket 7 in Embodiment 4.

[0044] For the above four methods, attention should be paid to the direction of the air guiding plate 8 during assembly. It is necessary to ensure that the air guiding plates 8 on multiple core barrels are consistent to ensure the air guiding effect. The core barrels of the first and second methods are independent. Each core barrel is individually fixed and installed in the cylinder body 1, and the installation spacing of each core barrel in the cylinder body 1 can be adjusted individually, which is more flexible. For the third and fourth methods, different core barrels need to be connected to each other to be used, and they are more firm after assembly.

[0045] In this application, the core barrel is combined with the cylinder body 1 and used with an external dryer. The hot air of the external dryer enters the inside of the cylinder body 1. The feeding machine puts the sludge into the inside of the cylinder body 1. The blade 111 and the connecting rod 113 convey and pound the sludge, and convey the sludge into the cylinder body 1. The supporting wheel 15 drives the cylinder body 1 to rotate. The stirring plate 4 and the stirring basket 7 inside the cylinder body 1 drive the sludge to turn over by grasping the sludge. When the cylinder body 1 rotates, it drives the air guiding plate 8 to rotate, and quickly introduces the hot air generated by the external dryer into the inside of the cylinder body 1. The hot air enters the core barrel and between the cylinder body 1 and the core barrel to bake the sludge. The dried sludge is discharged from the discharge end. It should be emphasized that some other materials can also be synchronously input during the sludge drying process. By using the function of the stirring device, the materials are mixed into the sludge. In this way, the dried sludge mixture can be reused as nutrient soil, and the formed nutrient soil has multiple utilization values: (1) as a special soil for indoor and outdoor potted plants; (2) as a fertilizer for greenhouse vegetable cultivation; (3) for soil improvement of greening projects such as parks and streets; (4) as a germination substrate for breeding seeds, etc. It has a wide range of uses, is suitable for various plant growth scenarios, realizes the transformation of sludge from waste to treasure during the water channel treatment process, and has high economic value.
