A mixing device for solidifying waste mud

Abstract

This utility model discloses a mixing device for solidifying waste mud, comprising: a mixing unit, the mixing unit including a mixing tank, a controller installed on one side of the mixing tank, a mud inlet on the other side of the mixing tank, and a discharge outlet on the lower side of the mixing tank. In this utility model, mud enters the mixing tank through the mud inlet, and then a solidifying agent is injected into the interior of a circular tube through a feed pipe. A drive motor then drives a rotating shaft to rotate inside the mixing tank, causing the circular tube, fixedly connected to the rotating shaft, to drive the solidification unit via a transmission unit. This allows the solidifying agent to be evenly distributed inside the mixing tank through the solidification unit. Simultaneously, a stirring rod fixedly connected to the rotating shaft rotates and stirs the mud and solidifying agent, effectively accelerating the mixing speed of the solidifying agent and mud and improving the solidification effect of the mud.

Description

Technical Field

[0001] This utility model relates to the technical field of mud mixing, and in particular to a mixing device for solidifying waste mud. Background Technology

[0002] The waste mud solidification and mixing device mixes waste mud with solidifying agents and other substances in a mixing tank, and then rotates the mixing blades to mix them evenly to achieve the purpose of solidification. The solidified mud can be used for road base stabilization, waste mud solidification, soil improvement and other projects.

[0003] Existing waste mud solidification and mixing devices typically have an injection port installed on the upper side of the mixing tank.

[0022] Example 1 Reference Figure 1-2 This is the first embodiment of the present invention, which provides a waste mud solidification treatment mixing device, comprising: The mixing unit 100 includes a mixing tank 101, and a controller 104 is installed on one side of the mixing tank 101. A mud inlet is provided on the other side of the mixing tank 101 for injecting mud. A discharge outlet is provided on the lower side of the mixing tank 101 for discharging the mixed mud. The curing unit 200 is disposed on the upper side of the mixing tank 101. The curing unit 200 includes a circular tube 203, and the inside of the circular tube 203 is provided with two sets of spiral blades 206 for uniformly injecting the curing agent into the mixing tank 101. The transmission unit 300 is disposed at one end of the fixed chamber 201. The transmission unit 300 includes a rotating gear 302 for driving the spiral blade 206 to rotate inside the circular tube 203.

[0023] Furthermore, a drive motor 105 is fixedly connected to the lower surface of the mixing tank 101, and a rotating shaft 102 is fixedly connected to the output shaft of the drive motor 105. The drive motor 105 is electrically connected to the controller 104. The surface of the rotating shaft 102 is rotatably connected to the mixing tank 101. Multiple sets of stirring rods 103 are fixedly connected to the surface of the rotating shaft 102 to stir the mud and solidifying agent inside the mixing tank 101.

[0024] In use, the slurry enters the mixing tank 101 through the slurry inlet, and then the curing agent is injected into the round tube 203 through the feed pipe 202. Then, the drive motor 105 drives the rotating shaft 102 to rotate inside the mixing tank 101, so that the round tube 203, which is fixedly connected to the rotating shaft 102, drives the curing unit 200 through the transmission unit 300. This allows the curing agent to be evenly distributed inside the mixing tank 101 through the curing unit 200. At the same time, the stirring rod 103, which is fixedly connected to the rotating shaft 102, rotates and stirs the slurry and curing agent, which can effectively accelerate the mixing speed of the curing agent and slurry and improve the curing effect of the slurry.

[0025] Example 2 Reference Figure 2-5 This is the second embodiment of the present invention. Unlike the previous embodiment, the curing unit 200 includes a fixed chamber 201 fixedly connected to the mixing tank 101. A feed pipe 202 is installed on the upper surface of the fixed chamber 201. A rotating pipe 204 is rotatably connected inside the feed pipe 202. A round pipe 203 is installed at the lower end of the rotating pipe 204. The lower surface of the round pipe 203 is fixedly connected to the rotating shaft 102. A rotating rod 205 is rotatably connected inside the round pipe 203. The surface of the rotating rod 205 is fixedly connected to two sets of spiral blades 206. Multiple sets of discharge pipes 207 are evenly installed on the lower surface of the round pipe 203. The rotating shaft 102 drives the round pipe 203 to rotate inside the fixed chamber 201, so that the curing agent inside the round pipe 203 is evenly sprinkled into the interior of the mixing tank 101.

[0026] Furthermore, the two sets of spiral blades 206 are arranged horizontally symmetrically with the rotation shaft 102 as the center, and both sets of spiral blades 206 are movably connected to the inner wall surface of the circular tube 203, so that the two sets of spiral blades 206 push the curing agent into the circular tube 203.

[0027] Furthermore, a guide plate 208 is fixedly connected to the inner wall surface of the circular tube 203, and both sides of the guide plate 208 are designed to be inclined. The guide plate 208 is rotatably connected to the surface of the rotating rod 205 to divert the curing agent entering through the rotating tube 204.

[0028] Furthermore, a connecting plate 210 is fixedly connected to the inner wall surface of the fixed chamber 201, and a fixing ring 209 is fixedly connected to the middle of the connecting plate 210. The fixing ring 209 is rotatably connected to the rotating shaft 102. The upper surface of the connecting plate 210 is movably connected to multiple sets of discharge pipes 207. The two sides of the connecting plate 210 are arc-shaped to support the rotating shaft 102. At the same time, the upper surface of the connecting plate 210 can scrape and clean the lower end of the discharge pipes 207.

[0029] Furthermore, the transmission unit 300 includes a rack ring 301 fixedly connected to the inner wall surface of the fixed chamber 201, and a rotating gear 302 is meshed inside the rack ring 301. A rotating shaft 303 is fixedly connected to the lower side of the rotating gear 302, and a side plate is rotatably connected to the surface of the rotating shaft 303. The side plate is fixedly connected to the circular tube 203. A bevel gear 304 is fixedly connected to the lower end of the rotating shaft 303, and a bevel gear 305 is meshed on one side of the bevel gear 304. The bevel gear 305 is fixedly connected to the rotating rod 205, and can drive the rotating rod 205 to rotate on the inner wall of the circular tube 203 when the circular tube 203 rotates.

[0030] Furthermore, a fixed brush 306 is movably connected to the inner side of the rack ring 301, and the fixed brush 306 is fixedly connected to the surface of the round tube 203. The round tube 203 drives the fixed brush 306 to rotate, cleaning the surface of the rack ring 301.

[0031] In use, the slurry enters the mixing tank 101 through the slurry inlet, and then the curing agent is injected into the rotating pipe 204 through the feed pipe 202, and then enters the round pipe 203 through the rotating pipe 204. Next, the drive motor 105 drives the rotating shaft 102 to rotate inside the mixing tank 101, causing the round pipe 203, which is fixedly connected to the rotating shaft 102, to rotate inside the fixed chamber 201. This causes the rack ring 301, which is fixedly connected to the fixed chamber 201, to rotate. The rotating shaft 303, which is fixedly connected to the rotating gear 302, rotates. The first bevel gear 304 is driven to rotate, causing the second bevel gear 305, which is meshed with the first bevel gear 304, to drive the rotating rod 205 to rotate inside the fixed chamber 201. This, in turn, causes the spiral blade 206, which is fixedly connected to the rotating rod 205, to rotate, pushing the curing agent inside the round tube 203 to move inside the round tube 203 and to be evenly spread downward through the discharge pipe 207 into the interior of the mixing tank 101, where it comes into contact with the slurry inside the mixing tank 101. At the same time, the stirring rod 103, which is fixedly connected to the rotating shaft 102, rotates and mixes the slurry and the curing agent.
