Description

Technical Field

[0001] This utility model relates to the technical field of sludge treatment equipment, and in particular to an aging device for solid waste sludge and slag before granulation. Background Technology

[0002] The aging process is the process by which sludge undergoes physical, chemical, and biological changes over time under specific conditions. Aging is a secondary fermentation stage, in which microorganisms slowly decompose recalcitrant organic matter, increase the degree of humification, and allow the raw materials to stand still to improve the uniformity of mixing and release internal stress, thereby enabling the sludge to be used in agricultural fertilizers or brick making and other fields.

[0003] When sludge is piled up and aged, it is necessary to prevent the pile from turning into an anaerobic state due to lack of oxygen, which could cause the sludge to smell bad and produce toxins. Therefore, the piled sludge needs to be turned over regularly. However, in aerobic aging scenarios, when turning over the piled sludge, continuous turning can easily lead to large temperature fluctuations in the pile, which may affect the inactivation efficiency of microorganisms against pathogens during the high-temperature period. Frequent turning may also damage the pore structure that has been formed inside the sludge, resulting in uneven oxygen supply in the short term. In addition, large-scale pile turning requires area-by-area operation, which is time-consuming. Utility Model Content

[0004] The purpose of this invention is to provide an aging device for solid waste sludge and residue before granulation, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An aging device for solid waste sludge and residue before granulation includes an aging tank. A hydraulic station is fixedly installed on one side of the aging tank. Tilting mechanisms are provided on both sides of the top of the aging tank, and a pipe beam is provided between two tilting mechanisms on the same side. Multiple air pipes are fixedly installed at the bottom of the pipe beam, and a connecting tee pipe is fixedly installed between two air pipes. A static ventilation frame is provided at one end of the connecting tee pipe. The static ventilation frame includes a connecting pipe fixedly installed at one end of the connecting tee pipe, and multiple longitudinal air conveying plates and transverse air conveying plates. The multiple longitudinal air conveying plates and transverse air conveying plates are fixedly connected to each other, and one of the transverse air conveying plates is also fixedly installed at one end of the connecting pipe.

[0007] As a further preferred embodiment of this utility model, the aging tank is a three-sided cavity enclosure structure, with one side of the aging tank set as an open structure, which facilitates external mechanical equipment to pile sludge into the aging tank or to remove the aged sludge from the aging tank.

[0008] As a further preferred embodiment of this utility model, the flipping mechanism further includes a base, which is fixedly installed on the aging tank. Two bearings are fixedly installed on the base, and a flipping frame is rotatably connected between the two bearings. Two cylinders are also movably connected between the flipping frame and the base. The cylinders are connected to a hydraulic station through hydraulic pipes. Two mounting seats are also fixedly installed on the side of the flipping frame away from the bearings. The pipe beam is fixedly connected to one side of the multiple mounting seats. After the flipping frame is rotatably installed on the two bearings, it can be flipped in conjunction with the cylinders to achieve the flipping of the flipping frame. Thus, when sludge is piled into the aging tank, the static ventilation frame is flipped out of the aging tank through the flipping frame, pipe beam, and air pipe, which facilitates the mechanical handling of sludge.

[0009] As a further preferred embodiment of this utility model, one of the longitudinal air conveying plates has connecting grooves on both sides, and a connecting air conveying plate is interlaced between two connecting grooves at the same horizontal position.

[0010] As a further preferred embodiment of this utility model, the longitudinal sections of the longitudinal air conveying plate, the transverse air conveying plate and the connecting air conveying plate are all prismatic. The longitudinal air conveying plate, the transverse air conveying plate and the connecting air conveying plate are set as prismatic hollow structures, which are easy to insert into the sludge, thereby realizing the function of supplying air to the sludge.

[0011] As a further preferred embodiment of this utility model, air outlet grooves are respectively provided on both sides of the longitudinal air conveying plate, the transverse air conveying plate, and the connecting air conveying plate. Two expansion plates are fixedly installed in the air outlet grooves, and the longitudinal cross-section of the two expansion plates is triangular. One side of the two expansion plates is attached to each other. The multiple air outlet grooves on both sides of the longitudinal air conveying plate, the transverse air conveying plate, and the connecting air conveying plate facilitate the supply of air to the sludge with the help of an external air pump. At the same time, the two expansion plates are provided in the air outlet grooves. When air is supplied, the side of the two expansion plates that are attached can separate to release air. When air supply stops, one side of the two expansion plates will automatically attach, reducing the probability of sludge entering the inner cavity of the longitudinal air conveying plate, the transverse air conveying plate, and the connecting air conveying plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, multiple turning mechanisms are installed at the top of the aging tank, and a pipe beam is installed between two turning mechanisms on the same side. Multiple sets of air pipes, connecting tee pipes, and a static ventilation frame structure are installed at the bottom of the pipe beam. These structures can be inserted into the sludge in conjunction with the turning mechanisms to supply air to the sludge on demand. This eliminates the need for turning the sludge, thus creating an aerobic aging environment in the sludge and avoiding the risk of localized anaerobic conditions caused by interrupted turning. Furthermore, the static ventilation frame can be turned over when the sludge is being removed or placed, without affecting the operation of the mechanical equipment in the aging tank.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-6 As shown, the present invention provides an aging device for solid waste sludge and slag before granulation, including an aging tank 1, a hydraulic station 2 fixedly installed on one side of the aging tank 1, a tilting mechanism 3 on both sides of the top of the aging tank 1, and a pipe beam 4 between two tilting mechanisms 3 on the same side, a plurality of air pipes 5 fixedly installed at the bottom of the pipe beam 4, a connecting tee pipe 6 fixedly installed between two air pipes 5, a static ventilation frame 7 provided at one end of the connecting tee pipe 6, the static ventilation frame 7 including a connecting pipe 8 fixedly installed at one end of the connecting tee pipe 6, a plurality of longitudinal air conveying plates 9 and transverse air conveying plates 10, and the plurality of longitudinal air conveying plates 9 and transverse air conveying plates 10 fixedly connected to each other, and one of the transverse air conveying plates 10 is also fixedly installed at one end of the connecting pipe 8.

[0023] like Figures 1-4As shown, the aging tank 1 has a three-sided enclosed structure, with one side of the aging tank 1 being open to facilitate the placement of sludge into the aging tank 1 by external mechanical equipment or the removal of aged sludge from the aging tank 1. The tilting mechanism 3 also includes a base 11, which is fixedly installed on the aging tank 1. Two bearing seats 12 are fixedly installed on the base 11, and a tilting frame 13 is rotatably connected between the two bearing seats 12. Two cylinders 1 are also movably connected between the tilting frame 13 and the base 11. 4. The cylinder 14 is connected to the hydraulic station 2 through a hydraulic pipe. Two mounting seats 15 are also fixedly installed on the side of the tilting frame 13 away from the bearing seat 12. The pipe beam 4 is fixedly connected to one side of multiple mounting seats 15. After the tilting frame 13 is rotated and installed on the two bearing seats 12, it can be rotated in conjunction with the cylinder 14 to achieve the tilting of the tilting frame 13. Then, when sludge is piled into the aging tank 1, the static ventilation frame 7 is tilted out of the aging tank 1 through the tilting frame 13, the pipe beam 4, and the air pipe 5, which facilitates the mechanical handling of sludge.

[0024] like Figures 1-6 As shown, a connecting groove 16 is provided on both sides of one of the longitudinal air conveying plates 9. A connecting air conveying plate 17 is interlaced between two connecting grooves 16 at the same horizontal position. The longitudinal cross-sections of the longitudinal air conveying plate 9, the transverse air conveying plate 10, and the connecting air conveying plate 17 are all prismatic. The longitudinal air conveying plate 9, the transverse air conveying plate 10, and the connecting air conveying plate 17 are set as prismatic hollow structures, which facilitates insertion into the sludge and flexibly expands the ventilation structure, thereby realizing the function of supplying air to the sludge. An air outlet groove 18 is provided on both sides of the longitudinal air conveying plate 9, the transverse air conveying plate 10, and the connecting air conveying plate 17. The air outlet groove 18 is solid. Two expansion plates 19 are fixedly installed, and the longitudinal cross-section of the two expansion plates 19 is triangular. One side of the two expansion plates 19 is attached to each other. Multiple air outlet slots 18 are opened on both sides of the longitudinal air conveying plate 9, the transverse air conveying plate 10, and the connecting air conveying plate 17 to facilitate the supply of air to the sludge with the help of an external air pump. At the same time, two expansion plates 19 are installed in the air outlet slots 18. When air is supplied, the side of the two expansion plates 19 that is attached can separate to release air. When air supply stops, one side of the two expansion plates 19 will automatically attach, reducing the probability of sludge entering the inner cavity of the longitudinal air conveying plate 9, the transverse air conveying plate 10, and the connecting air conveying plate 17.

[0025] It should be noted that this utility model is an aging device for solid waste sludge and slag before granulation. After the sludge and slag are piled into the aging tank 1 by external unloading equipment, the hydraulic station 2 is started by an external controller. The hydraulic station 2 then provides power to the cylinder 14, driving the tilting frame 13 to rotate around the shaft seat 12. This causes the pipe beam 4, the air pipe 5 fixed at its bottom, the connecting tee pipe 6, and the static ventilation frame 7 to tilt. Thus, the static ventilation frame 7 is inserted into the sludge pile in the aging tank 1. At this time, the external... The air pump supplies air to multiple static ventilation frames 7 simultaneously through connecting pipes, air pipes 5, and connecting tee pipes 6. The air enters the longitudinal air conveying plate 9, the transverse air conveying plate 10, and the connecting air conveying plate 17 through the connecting pipe 8, and then is discharged through the gaps of the expansion plates 19 in the air outlet slots 18 on both sides, providing an aerobic environment for the sludge. The prismatic cross-section of the longitudinal air conveying plate 9, the transverse air conveying plate 10, and the connecting air conveying plate 17 facilitates the insertion of sludge. When air is supplied, the expansion plates 19 open to release air, and when air is stopped, they close to prevent sludge from entering the internal cavity.
