Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically to a drying and solidification device for oily sludge. Background Technology

[0002] Oily sludge refers to solid waste generated during oil extraction, transportation, and oily wastewater treatment. Pit storage or stockpiling can cause great harm to the surrounding soil, water bodies, and air environment. Existing oily sludge drying and solidification treatment devices do not mix sludge and solidifying agents sufficiently, resulting in the sludge solidification effect of existing oily sludge drying and solidification treatment devices needing improvement.

[0003] In response, Chinese patent application number CN202321814364.4 discloses an oily sludge drying and solidification treatment device, including a mixing tank. A feed valve is fixedly connected to the top of the mixing tank, and a solidifying agent spraying assembly is installed on the top of the mixing tank. A mixing and stirring assembly is installed inside the mixing tank, and a plate filter press is installed on the left side of the mixing and stirring assembly. The solidifying agent spraying assembly includes a storage tank fixedly installed on the top of the mixing tank. A U-shaped pipe is fixedly connected to the top of the storage tank, and a water pump is fixedly connected to the left end of the U-shaped pipe. An L-shaped outlet pipe is fixedly connected to the left side of the water pump, and a connecting pipe is fixedly connected to the bottom end of the L-shaped outlet pipe. This oily sludge drying and solidification treatment device provides a function for fully mixing sludge and solidifying agent, and also provides a conveying function, thereby effectively improving the sludge solidification effect of existing oily sludge drying and solidification treatment devices.

[0004] This device uses a mixing tank to mix sludge and solidifying agent to ensure the solidification effect of the sludge. However, the sludge is quite viscous, and after entering the mixing tank, it can only move by the guide platform, resulting in a slow flow speed, which seriously affects the efficiency of the device. In addition, the mixing blades only stir in one direction, resulting in poor mixing effect between the sludge and solidifying agent.

[0005] Therefore, in order to solve the above problems, a drying and solidification treatment device for oily sludge is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide an oily sludge drying and solidification treatment device to solve the problem mentioned in the background art that the prior art device can mix sludge and solidifying agent by setting a mixing tank to ensure the solidification effect of sludge. However, the sludge is relatively viscous, and after entering the mixing tank, the sludge can only move by the guide platform, and the flow speed is slow, which seriously affects the efficiency of the device. In addition, the mixing blades stir in one direction, resulting in poor mixing effect between sludge and solidifying agent.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an oily sludge drying and solidification treatment device, comprising: a mixing tank, wherein a feed inlet is installed on the left end of the top surface of the mixing tank, a discharge outlet is installed on the right end of the bottom surface of the mixing tank, and a mixing rod is movably installed on the inner side of the mixing tank via a bearing, and a pulley is fixedly connected to the right end of the mixing rod;

[0008] A pushing structure is installed inside the mixing tank. The pushing structure includes a rotating shaft, which is movably mounted inside the mixing tank via bearings. A pusher arc frame is welded to the middle of the rotating shaft. A spray nozzle is provided on the left side wall of the rotating shaft and the pusher arc frame. A pusher plate is welded to the outer wall of the pusher arc frame. A motor is fixedly installed on the front of the mixing tank. A mounting frame is fixedly installed on the rear wall of the mixing tank. A rotary sealing joint is fixedly installed in the middle of the mounting frame. One end of the rotary sealing joint is fixedly connected to a liquid inlet pipe. A fan blade is fixedly connected to the left end of the stirring rod.

[0009] Preferably, the inner bottom surface of the mixing tank is an inclined surface that is higher on the left and lower on the right, and the pulley is located on the right side of the mixing tank.

[0010] Preferably, the rotating shaft and the stirring rod are arranged perpendicularly to each other, with the rotating shaft located on the upper side of the stirring rod.

[0011] Preferably, the pusher arc frame is arc-shaped and is sleeved on the outside of the stirring rod, and the shape of the pusher arc frame is adapted to the shape of the stirring rod.

[0012] Preferably, the output end of the motor is fixedly connected to the front end of the rotating shaft, and the rear end of the rotating shaft is fixedly connected to the other end of the mounting bracket.

[0013] Preferably, the rotating shaft and the pusher arc frame rotate counterclockwise.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a fan blade on the lower side of the feed inlet, the sludge can be pushed to the right when rotating, which facilitates its rapid discharge through the discharge port. Furthermore, a circumferentially oscillating pusher arc frame is set on the outside of the stirring rod, which can be immersed in the sludge when rotating and stir and push the sludge in a position perpendicular to the rotation direction of the stirring rod, ensuring the stirring effect of the sludge and improving the auxiliary pushing effect of the sludge.

[0015] This invention features a pushing structure that adds sludge to the inside of the mixing tank through the feed inlet. The sludge falls from the feed inlet onto the surface of the fan blades. The rotation of the stirring rod drives the fan blades to rotate, agitating the sludge and pushing it to the right. The stirring rod also agitates the sludge, allowing the solidifying agent to be introduced into the rotating shaft through the inlet pipe. The solidifying agent fills the pusher frame and is sprayed out through the spray nozzle. Starting the motor drives the rotating shaft, which in turn rotates the pusher frame and pusher plate. The pusher frame and pusher plate can swing counterclockwise above the stirring rod, and are immersed in... When not in the sludge, the sludge can be pushed to the right to accelerate its discharge through the outlet, shorten its residence time inside the mixing tank, and improve the efficiency of the device. The solidifying agent can be sprayed directly onto the inside of the sludge through the spray nozzle. When the pusher frame and pusher plate rotate above the mixing rod, they separate from the sludge. At this time, the solidifying agent can be sprayed onto the top surface of the sludge through the spray nozzle, which can improve the mixing effect between the solidifying agent and the sludge. The rotation direction of the pusher frame and pusher plate is perpendicular to the rotation direction of the mixing rod, ensuring the stirring effect on the sludge and improving the auxiliary pushing effect on the sludge.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 An embodiment of an oily sludge drying and solidification treatment device provided by this utility model:

[0023] The mixing tank 1, mixing rod 13 and motor 26 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0024] An oily sludge drying and solidification treatment device includes: a mixing tank 1, an inlet 11 installed on the left end of the top surface of the mixing tank 1, an outlet 12 installed on the right end of the bottom surface of the mixing tank 1, and a mixing rod 13 movably installed on the inner side of the mixing tank 1 via a bearing, with a pulley 14 fixedly connected to the right end of the mixing rod 13.

[0025] A pushing structure 2 is installed inside the mixing tank 1. The pushing structure 2 includes a rotating shaft 21, which is movably mounted inside the mixing tank 1 via bearings. A pusher arc frame 22 is welded to the middle of the rotating shaft 21. A spray nozzle 23 is provided on the left side wall of the rotating shaft 21 and the pusher arc frame 22. A pusher plate 24 is welded to the outer wall of the pusher arc frame 22. A motor 26 is fixedly installed on the front of the mixing tank 1. A mounting frame 27 is fixedly installed on the rear wall of the mixing tank 1. A rotary sealing joint 28 is fixedly installed in the middle of the mounting frame 27. One end of the rotary sealing joint 28 is fixedly connected to the liquid inlet pipe 29, and the left end of the stirring rod 13 is fixedly connected to the fan blade 210. By setting the fan blade 210 on the lower side of the feed inlet 11, the sludge can be pushed to the right when rotating, so as to be quickly discharged through the discharge port 12. A circular oscillating pusher arc frame 22 is set on the outside of the stirring rod 13, which can be immersed in the sludge when rotating, and stir and push the sludge in a position perpendicular to the rotation direction of the stirring rod 13, so as to ensure the stirring effect of the sludge and improve the auxiliary pushing effect of the sludge.

[0026] Furthermore, the inner bottom surface of the mixing tank 1 is a slope that is higher on the left and lower on the right, and the pulley 14 is located on the right side of the mixing tank 1, so that the sludge can flow along the slope.

[0027] Furthermore, the rotating shaft 21 and the stirring rod 13 are arranged perpendicularly to each other, with the rotating shaft 21 located on the upper side of the stirring rod 13. The rotating shaft 21 and the stirring rod 13 do not interfere with each other when rotating.

[0028] Furthermore, the pusher arc frame 22 is arc-shaped and is sleeved on the outside of the stirring rod 13. The shape of the pusher arc frame 22 is adapted to the shape of the stirring rod 13, and the pusher arc frame 22 will not come into contact with the stirring rod 13 when it swings.

[0029] Furthermore, the output end of the motor 26 is fixedly connected to the front end of the rotating shaft 21, and the rear end of the rotating shaft 21 is fixedly connected to the other end of the mounting bracket 27. The motor 26 provides power for the rotation of the rotating shaft 21. When the rotating shaft 21 rotates, the curing agent can be delivered to the inside of the rotating shaft 21 through the liquid inlet pipe 29 and the rotary sealing joint 28.

[0030] Furthermore, the rotating shaft 21 and the pushing arc frame 22 rotate counterclockwise. When the rotating shaft 21 and the pushing arc frame 22 are immersed in the sludge, they can be sleeved on the outside of the stirring rod 13. The right side wall of the rotating shaft 21 and the pushing arc frame 22 will push the sludge, while the spray nozzle 23 located on the left side wall of the rotating shaft 21 and the pushing arc frame 22 can spray the curing agent into the sludge.

[0031] Working principle: Before use, connect the pulley 14 to an external power source, which will make the pulley 14 and the stirring rod 13 rotate.

[0032] In use, sludge is added to the inside of the mixing tank 1 through the feed inlet 11. The sludge falls from the feed inlet 11 onto the surface of the fan blades 210. The rotation of the stirring rod 13 drives the fan blades 210 to rotate. When the fan blades 210 rotate, they agitate the sludge and push it to the right. The stirring rod 13 agitates the sludge, and the curing agent is introduced into the rotating shaft 21 through the liquid inlet pipe 29. The curing agent fills the pusher arc frame 22 and is sprayed out through the spray nozzle 23. Starting the motor 26 drives the rotating shaft 21 to rotate. When the rotating shaft 21 rotates, it drives the pusher arc frame 22 and the pusher plate 24 to rotate. The pusher arc frame 22 and the pusher plate 24 can swing counterclockwise on the upper side of the stirring rod 13. When the pusher plate 24 is submerged in the sludge, it can push the sludge to the right to accelerate the discharge speed of the sludge through the outlet 12, shorten the residence time of the sludge inside the mixing tank 1, and improve the efficiency of the device. The curing agent can be directly sprayed onto the inside of the sludge through the spray nozzle 23. When the pusher arc frame 22 and the pusher plate 24 are rotated to the upper side of the stirring rod 13, the pusher arc frame 22 and the pusher plate 24 are separated from the sludge. At this time, the curing agent can be sprayed onto the top surface of the sludge through the spray nozzle 23, which can improve the mixing effect between the curing agent and the sludge. The rotation direction of the pusher arc frame 22 and the pusher plate 24 is perpendicular to the rotation direction of the stirring rod 13, which ensures the stirring effect of the sludge and improves the auxiliary pushing effect of the sludge.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
