Description

Technical Field

[0001] This utility model relates to the field of atomizing spray guns, and in particular to a sludge atomizing spray gun for waste incineration. Background Technology

[0002] Sludge, as a byproduct of wastewater treatment, has a significant impact on the environment. Therefore, the harmless, reduced-volume, and resource-based treatment of sludge is urgently needed. Co-firing sludge from waste-to-energy plants is one method to achieve maximum sludge volume reduction.

[0003] Chinese patent CN217221972U discloses a sludge spray gun, which is easy to use by setting a sludge nozzle and an inner tube. The sludge nozzle, together with the atomizing nozzle on the inner tube, atomizes the sludge and sprays it out. The atomizing nozzles are arranged in a ring array to make the sludge more fully atomized when sprayed out, thereby increasing the spray area and improving the atomization effect, effectively realizing the atomization and spraying of sludge.

[0004] Traditional sludge atomizing spray guns cannot fully refine sludge particles during use, resulting in low combustion efficiency. At the same time, sludge and other impurities are easily left inside the equipment, making cleaning and maintenance difficult, affecting the service life of the equipment, resulting in low sludge treatment efficiency and inconvenient equipment maintenance. Utility Model Content

[0005] The core of this invention lies in solving the problems of low sludge treatment efficiency and inconvenient maintenance in the existing technology by optimizing the structural design of the sludge atomizing spray gun.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A sludge atomizing spray gun for waste incineration includes an inner cylinder, an outer cylinder fixedly connected to the front end of the inner cylinder, a sludge input pipe fixedly connected to the lower end of the tail of the inner cylinder, a pair of auxiliary liquid pipes fixedly connected to the middle of the outer cylinder, and an air duct connected to the middle of the tail of the inner cylinder.

[0008] The outer cylinder includes an outer sleeve, inside which an inner sleeve is connected and communicates with the outer sleeve. Two auxiliary liquid pipes are connected to the outer sleeve and the inner sleeve, respectively. A nozzle is connected to the top of the inner cylinder, and a sealing cap matching the air duct is connected to the tail end of the inner cylinder. An auxiliary liquid spray hole communicating with the inner sleeve is provided on the nozzle.

[0009] The air duct includes an air guide tube inserted into the inner cylinder and rotatably connected to the sealing cap. The top end of the air guide tube is connected to a nozzle located inside the nozzle. The end of the air guide tube near the outer side of the inner cylinder is rotatably connected to an air delivery tube. A fixed plate is connected to the air delivery tube, and multiple fixed rods are connected between the fixed plate and the sealing cap.

[0010] Furthermore, the sealing cap has a locking hole that matches the nozzle, and the opening end of the locking hole is rotatably connected to a rotating cap, which is fixedly connected to the air guide pipe; the outer wall of one end of the air guide pipe has an external thread, and a piston disc that matches the air guide pipe is slidably connected inside the inner cylinder, and the piston disc is sleeved on the air guide pipe and threadedly connected to the air guide pipe; the inner wall of the inner cylinder is provided with a limiting slide bar that slides relative to the piston disc.

[0011] Optionally, the sealing cap has a locking hole that matches the nozzle, and the opening end of the locking hole is rotatably connected to a rotating cap, which is fixedly connected to the air guide tube; the air guide tube has an external thread on the outer wall of one end of the inner cylinder, and a piston disc that matches the air guide tube is slidably connected inside the inner cylinder, and the piston disc is sleeved on the air guide tube and threadedly connected to the air guide tube; the inner wall of the inner cylinder is provided with a limiting slide bar that slides relative to the piston disc.

[0012] Furthermore, an airflow input pipe is connected to the gas supply pipe, and the airflow input pipe is detachably connected to the side of the fixed plate away from the inner cylinder.

[0013] Furthermore, a sealing ring is connected between the top ends of the outer sleeve and the inner sleeve, and the top end of the inner sleeve is sealed to the top end of the nozzle.

[0014] Furthermore, a fixed flange is fixedly connected to the outer wall of the inner cylinder, and the fixed flange is fixedly connected to both the outer sleeve and the inner sleeve.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) This solution optimizes the structural design of the sludge atomizing spray gun, uses high-pressure airflow to disperse the industrial sludge sprayed from the nozzle, making its particles finer and more evenly dispersed. Furthermore, leachate is precisely sprayed into the sealing cover and nozzle through the auxiliary liquid pipe, effectively removing residual sludge or other impurities. This not only protects the spray gun head but also extends the service life of the equipment.

[0017] (2) Through the linkage design of the rotating cover and the air guide pipe, the piston disc slides along the limiting slide bar, which can easily push the sludge remaining in the inner cylinder to the nozzle. This structure simplifies cleaning and maintenance work and improves maintenance efficiency. Attached Figure Description

[0025] The technical solution will now be clearly and completely described with reference to the accompanying drawings of the embodiments of this utility model.

[0026] First implementation method:

[0027] Please see Figures 1-3 A sludge atomizing spray gun for waste incineration includes an inner cylinder 1, an outer cylinder 2 fixedly connected to the front end of the inner cylinder 1, a sludge input pipe 3 fixedly connected to the lower end of the tail of the inner cylinder 1, a pair of auxiliary liquid pipes 4 fixedly connected to the middle of the outer cylinder 2, and an air duct 5 connected to the middle of the tail of the inner cylinder 1.

[0028] The outer cylinder 2 includes an outer sleeve 21, and an inner sleeve 22 connected to and communicating with the outer sleeve 21. The inner sleeve 22 has a guide hole that communicates with the outer sleeve 21. Two auxiliary liquid pipes 4 are respectively connected to the outer sleeve 21 and the inner sleeve 22. The top end of the inner cylinder 1 is connected to a nozzle 11, and the tail end of the inner cylinder 1 is connected to a sealing cap 12 that matches the air duct 5. The nozzle 11 has an auxiliary liquid spray hole that communicates with the inner sleeve 22. After the auxiliary liquid pipe 4 enters the outer cylinder 2, it is guided by the outer sleeve 21 and the inner sleeve 22 and finally flows to the area at the top of the inner sleeve 22 corresponding to the outside of the nozzle 11. Finally, the auxiliary liquid is sprayed into the nozzle 11 through the auxiliary liquid spray hole. The auxiliary liquid used is selected by those skilled in the art from suitable liquids in the prior art, including but not limited to: cleaning liquid, penetrating liquid, and diluent.

[0029] A fixed flange 13 is fixedly connected to the outer wall of the inner cylinder 1. The fixed flange 13 is fixedly connected to both the outer sleeve 21 and the inner sleeve 22. A sealing ring is connected between the top ends of the outer sleeve 21 and the inner sleeve 22. The top end of the inner sleeve 22 is sealed to the top end of the nozzle 11.

[0030] The air duct 5 includes an air duct 51 inserted into the inner cylinder 1 and rotatably connected to the sealing cover 12. The top end of the air duct 51 is connected to a nozzle 52 located inside the nozzle 11. An air supply pipe 53 is rotatably connected to one end of the air duct 51 near the outer side of the inner cylinder 1. A fixing plate 531 is connected to the air supply pipe 53, and multiple fixing rods 54 are connected between the fixing plate 531 and the sealing cover 12.

[0031] An air inlet pipe is connected to the gas supply pipe 53, and the air inlet pipe is detachably connected to the side of the fixed plate 531 away from the inner cylinder 1.

[0032] In the specific operation of this embodiment, the sludge to be treated is first smoothly introduced into the internal space of the inner cylinder 1 through the sludge input pipe 3, and then sprayed out from the nozzle 11 port; at the same time, high-pressure air is sprayed out at high speed through the nozzle 52, forming a strong airflow; this airflow effectively disperses the industrial sludge sprayed from the nozzle 11, making its particles finer and more evenly dispersed; after being dispersed in this way, the industrial sludge is then directly sent into the combustion chamber for efficient combustion treatment. Because the sludge particles are fully refined, they exhibit good atomization effect during combustion, significantly improving combustion efficiency and effect.

[0033] During periods when the system is not spraying sludge, a cleaning process is specifically designed to precisely spray leachate into the sealing cap 12 via auxiliary liquid pipes to maintain the equipment's optimal condition. This process effectively cleans the sealing cap 12 and the nozzles 52 inside, promptly removing any residual sludge or other impurities, thus playing a crucial role in protecting the spray gun nozzles and extending the equipment's service life. This approach ensures both high efficiency in sludge treatment and adequate equipment maintenance, demonstrating the comprehensiveness and practicality of the system design.

[0034] Second implementation method:

[0035] Please see Figures 4-5 Compared with the first embodiment, this embodiment differs in that it can optionally include: a locking hole matching the nozzle 52 is provided on the sealing cover 12, and a rotating cover 121 is rotatably connected to the opening end of the locking hole, and the rotating cover 121 is fixedly connected to the air guide pipe 51; an external thread is provided on the outer wall of one end of the air guide pipe 51 located inside the inner cylinder 1, and a piston disc 6 matching the air guide pipe 51 is slidably connected inside the inner cylinder 1, and the piston disc 6 is sleeved on the air guide pipe 51 and threadedly connected to the air guide pipe 51; a limiting slide bar that slides relative to the piston disc 6 is provided on the inner wall of the inner cylinder 1.

[0036] When the rotating cover 121 rotates, the air guide pipe 51 rotates synchronously, causing the piston disc 6 to slide along the limiting slide bar, thereby moving the sludge inside the inner cylinder 1. This facilitates pushing the residual sludge inside the inner cylinder 1 towards the nozzle 11, reducing the amount of sludge remaining in the inner cylinder 1 and facilitating subsequent cleaning, inspection, and maintenance of the inner cylinder 1. This embodiment is suitable for the maintenance of the inner cylinder 1, and this structure is simple to operate; simply rotating the rotating cover 121 is enough to push the sludge, improving the efficiency and convenience of maintenance.

[0037] The above description is merely a preferred embodiment of this utility model; it encompasses all the protection scope of this utility model. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be covered within the protection scope of this utility model.
