Description

Technical Field

[0001] This application relates to the field of sludge conditioner preparation, specifically to a stirring device for sludge conditioner preparation. Background Technology

[0002] Sludge conditioners are water treatment chemicals that improve dewatering efficiency by altering the structure and particle characteristics of sludge flocs through the addition of chemical agents. They include inorganic, organic, and compound conditioners, as well as coagulants. The mechanism of action of sludge conditioners is to disrupt the colloidal stability of sludge through charge neutralization and adsorption bridging, thereby reducing the sludge's moisture content.

[0003] Chinese patent document CN220835312U discloses a special mixing device for sludge conditioner, specifically a mixing tank. An agitator is rotatably connected inside the mixing tank, a sludge discharge pipe is located at the bottom of the tank, and a motor is located at the top of the tank. The motor shaft is connected to one end of the agitator. A cleaning assembly is installed inside the mixing tank. The cleaning assembly includes a diversion ring pipe installed on the inner wall of the mixing tank, which is slidably connected to the tank. An angled nozzle and a straight nozzle are located at the bottom of the diversion ring pipe, with the straight nozzle located inside the angled nozzle. A water supply pipe and a steam delivery pipe are connected to the top of the diversion ring pipe. A water pump is installed on the water supply pipe, located next to a valve on the water supply pipe. Valves are installed on both the steam delivery pipe and the water supply pipe, and a steam generator is connected to one end of the steam delivery pipe. This invention can clean the inside of the mixing tank in a timely manner, thereby ensuring the hygiene of the mixing tank and preventing residual sludge from adhering inside.

[0004] However, the above-mentioned patents rely solely on agitators for mixing, resulting in poor overall mixing performance. This can easily lead to material clumping, which then adheres to the inner wall of the mixing tank, increasing the difficulty of subsequent maintenance. Utility Model Content

[0005] In order to overcome the problem of material clumping and adhesion caused by poor stirring effect in the prior art, this application provides a stirring device for preparing sludge conditioner.

[0006] This application adopts the following technical solution: a stirring device for preparing sludge conditioner, including a tank and a stirring shaft passing through the tank. The top of the tank is provided with a feed pipe and a motor, and the bottom of the tank is provided with a discharge pipe and a support leg. The motor is used to drive the stirring shaft to rotate. The bottom of the stirring shaft is provided with stirring blades. The inside of the tank is provided with a mixing pipe, which is sleeved on the outside of the stirring shaft and located above the stirring blades.

[0007] The outer wall of the mixing pipe is connected to the inner wall of the tank by a connecting rod. The outer wall of the mixing pipe is provided with several perforations, through which the material in the tank can enter the inner side of the mixing pipe.

[0008] Optionally, the outer edge of the mixing pipe is located inside the mixing range formed by the stirring blades.

[0009] Optionally, the tank body is further provided with a guide pipe, the inner diameter of which is smaller than the inner diameter of the feed pipe. One end of the guide pipe is connected to the feed pipe, and the other end of the guide pipe is located above the mixing pipe and between the inner wall of the mixing pipe and the outer wall of the stirring shaft.

[0010] Optionally, a reducing pipe and a flexible joint are provided between the feed pipe and the guide pipe. One end of the flexible joint is connected to the feed pipe, and the other end of the flexible joint is connected to the reducing pipe. The flexible joint can extend and retract along its own axis and swing along its own radial direction.

[0011] Optionally, the guide tube is L-shaped, with its vertical end connected to the reducing pipe and its horizontal end inclined downwards.

[0012] Optionally, the upper part of the outer wall of the tank is provided with an oblique through hole, and a vibrating rod is inserted through the through hole. One end of the vibrating rod is located on the outside of the tank, and the other end of the vibrating rod is located on the inside of the tank. The height of one end of the vibrating rod is higher than the height of the other end of the vibrating rod. The vibrating rod can move back and forth along the axial direction of the through hole and vibrate the guide pipe.

[0013] Optionally, a limiting tube is provided on the outer wall of the tank, the limiting tube is coaxially arranged with the through hole, the vibrating rod passes through the limiting tube, and the inner wall of the limiting tube is in contact with the outer wall of the vibrating rod.

[0014] Compared with the prior art, this application has the following advantages:

[0015] 1. Installing a mixing pipe inside the tank, along with an agitator shaft and agitator blades, can improve the mixing effect of materials, prevent material from clumping, and reduce material clumping. This also prevents materials from adhering to the inner wall of the tank, reducing the difficulty of subsequent maintenance.

[0016] 2. The material is reliably moved within the feed pipe and guide pipe by the vibration action of the vibrating rod on the guide pipe. Attached Figure Description

[0021] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] like Figure 1-3 As shown, the mixing device for preparing sludge conditioner includes a tank 1 and a mixing shaft 2 inserted inside the tank 1. The top of the tank 1 is provided with a feed pipe 11 and a motor 21, and the bottom of the tank 1 is provided with a discharge pipe 12 and a support leg 13. The motor 21 is used to drive the mixing shaft 2 to rotate. The bottom of the mixing shaft 2 is provided with mixing blades 22. The inside of the tank 1 is provided with a mixing pipe 3, which is sleeved on the outside of the mixing shaft 2 and located above the mixing blades 22. The outer wall of the mixing pipe 3 is connected to the inner wall of the tank 1 by a connecting rod 31. The outer wall of the mixing pipe 3 is provided with several perforations 32, through which the material in the tank 1 can enter the inner side of the mixing pipe 3.

[0023] When the motor 21 drives the stirring shaft 2 to rotate, the stirring blades 22 will rotate synchronously. As a result, the material will tumble in the lower inner part of the tank 1. During the tumbling process, some material will pass through the perforation 32 and enter the inner side of the mixing pipe 3, and eventually fall back to the bottom of the inner side of the tank 1. The material will have a cutting effect during the process of passing through the perforation 32, thereby significantly improving the stirring effect of the material.

[0024] The outer edge of the mixing pipe 3 is located inside the mixing range formed by the stirring blade 22. In other words, the mixing range formed by the rotation of the stirring blade 22 is larger than the range of the mixing pipe 3. This ensures that the material is stirred in the tank 1 and causes the material to roll towards the outside of the mixing pipe 3, thereby increasing the probability that the material enters the mixing pipe 3 through the perforation 32.

[0025] The tank body 1 is also equipped with a guide pipe 4. The inner diameter of the guide pipe 4 is smaller than that of the feed pipe 11. One end of the guide pipe 4 is connected to the feed pipe 11, and the other end of the guide pipe 4 is located above the mixing pipe 3 and between the inner wall of the mixing pipe 3 and the outer wall of the stirring shaft 2. The larger inner diameter of the feed pipe 11 allows for easy feeding of materials into the feed pipe 11, while the smaller inner diameter of the guide pipe 4 improves the guiding effect of the guide pipe 4 on the flow direction of materials, ensuring that the materials can be fed to the center of the vortex formed by the tumbling of materials, maximizing the dispersion of materials, and thus improving the final mixing effect.

[0026] A reducing pipe 41 and a flexible joint 42 are provided between the feed pipe 11 and the guide pipe 4. One end of the flexible joint 42 is connected to the feed pipe 11, and the other end of the flexible joint 42 is connected to the reducing pipe 41. The flexible joint 42 can extend and retract along its own axis and swing along its own radial direction. The reducing pipe 41 can reliably connect the feed pipe 11 and the guide pipe 4. Under the flexible connection of the flexible joint 42, the guide pipe 4 can generate a small range of movement, thereby realizing the dynamic change of the feeding point and further improving the material dispersion effect.

[0027] The feed pipe 4 is L-shaped. The vertical end of the feed pipe 4 is connected to the reducing pipe 41, and the horizontal end of the feed pipe 4 is inclined downward. In this way, after the material enters the feed pipe 4, it can automatically slide down between the mixing pipe 3 and the stirring shaft 2 under the action of gravity.

[0028] The upper part of the outer wall of the tank body 1 is provided with an oblique through hole 14. A vibrating rod 5 is inserted through the through hole 14. One end of the vibrating rod 5 is located on the outside of the tank body 1, and the other end of the vibrating rod 5 is located on the inside of the tank body 1. The height of one end of the vibrating rod 5 is higher than the height of the other end of the vibrating rod 5. The vibrating rod 5 can move back and forth along the axial direction of the through hole 14 and vibrate the guide pipe 4. By dragging the vibrating rod 5, the vibrating rod 5 can achieve the vibrating effect on the guide pipe 4, thereby preventing the material from clogging in the guide pipe 4.

[0029] A limiting tube 15 is provided on the outer wall of the tank body 1. The limiting tube 15 is coaxially arranged with the through hole 14, and the vibrating rod 5 passes through the limiting tube 15. The inner wall of the limiting tube 15 is in contact with the outer wall of the vibrating rod 5. Under the limiting and guiding action of the limiting tube 15, the vibrating rod 5 can move more smoothly along the axial direction of the through hole 14. Furthermore, since the through hole 14 is inclined, when material adheres to the vibrating rod 5, the material will slide down into the tank body 1 along the inclined direction of the vibrating rod 5, preventing the material from being carried out to the outside of the tank body 1.

[0030] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
