Description

Technical Field

[0001] The utility model relates to the technical field of slurry stirring devices, in particular to a stirring component and a precision casting slurry stirrer. Background Art

[0002] In precision casting, the production of slurry is an important link, which is directly related to the strength of the mold shell and the quality of the casting. In actual production, there is a self-rotating "L"-shaped slurry barrel. Its principle is that the barrel containing the slurry is driven to rotate by a motor, and an "L"-shaped baffle is placed in the slurry, which plays a stirring role.

[0003] However, this stirring method often causes a large amount of particles to sink to the bottom, resulting in poor stirring effect. The particles will be discharged with the slurry, affecting the purity of the slurry, which is not conducive to the subsequent casting of precision workpieces and has certain shortcomings.

[0004] Therefore, a stirring assembly and a precision casting slurry agitator are provided to solve the above-mentioned problems. Utility Model Content

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Embodiment 1:

[0029] Reference Figure 1-5 The stirring assembly includes a rotating shaft 202, and also includes: a plurality of rod bodies 301, all of which are fixedly connected to the rotating shaft 202; a piston rod 302, which is slidably connected in the rod body 301, and one end of the piston rod 302 passes through the rod body 301; a spring member 303, which is connected in the rod body 301, and the spring member 303 is used for resetting the piston rod 302; a liquid inlet 304, which is arranged on the rod body 301, and the liquid inlet end of the liquid inlet 304 faces the bottom; a liquid outlet 305, which is communicated with the rod body 301, and the liquid outlet end of the liquid outlet 305 is located at the rotating shaft 202 At the top, a one-way valve is provided in the liquid inlet 304 and the liquid outlet 305; at the arc-shaped wall 103, the through end of the rod body 301 abuts against the arc-shaped wall 103, and also includes a drive motor 201, and the output end of the drive motor 201 is fixedly connected to the rotating shaft 202. The precision casting slurry agitator includes a stirring assembly and a tank body 1. The drive motor 201 is fixedly connected to the tank body 1, the rotating shaft 202 is located in the tank body 1, and the arc-shaped wall 103 is fixedly connected to the inner wall of the tank body 1, and the top and bottom of the tank body 1 are respectively provided with a feed port 101 and a discharge port 102.

[0030] The rod body 301 is a shell with a cavity inside, and the cavity is used for the movement of the internal piston rod 302.

[0031] In actual use, inject a proper amount of water, and finally start the drive motor 201. Under the action of the drive motor 201, the rod body 301 will rotate, thereby stirring the water in the tank body 1, and then the material to be stirred will be continuously poured into the tank body 1 through the feed port 101. At this time, the material will contact with the water, part of it will dissolve in the water, and part of it will gradually sink. However, with the rotation of the rod body 301, the piston rod 302 will continuously contact the arc wall 103, thereby causing the piston rod 302 to continuously move in the cavity, and then the external liquid and some particles will be sucked in through the liquid inlet 304, and then discharged through the liquid outlet 305. The discharged liquid is discharged from Figure 2 The liquid is discharged from the liquid outlet 305 shown, and then returns to the top of the liquid, so that the particles that are about to sink to the bottom return to the top of the liquid, reducing the situation where the particles cannot be stirred due to sinking to the bottom.

[0032] When the stirring is completed, the discharge port 102 can be opened to discharge the slurry, but part of the slurry will remain in the rod body 301 and the rotating shaft 202 and cannot be discharged. At this time, water needs to be re-injected to dilute the internal slurry until there is remaining water in the rod body 301. The one-way valve in the liquid inlet 304 can also be set to a detachable or electrically controlled mode. When the internal slurry needs to be discharged, the one-way valve can be removed, or the one-way valve can be closed to allow the slurry to be discharged naturally.

[0033] Embodiment 2:

[0034] Reference Figure 1-5 The stirring assembly and the precision casting slurry agitator are basically the same as those in Example 1, and further, a filter screen 3041 is connected to the liquid inlet 304, and a rubber head 306 is connected to the through end of the piston rod 302.

[0035] The filter screen 3041 can prevent larger particles from entering the cavity and blocking the liquid outlet 305. The large particles blocking the filter screen 3041 will gradually melt under the cooperation of rotation and water and finally enter the cavity.

[0036] The rubber head 306 can reduce the damage to the arc-shaped wall 103 during rotation, and is convenient for long-term use.

[0037] The utility model can absorb the liquid and particles near the bottom and then discharge them from the top, thereby reducing the sedimentation of the particles, promoting the dissolution of the particles, facilitating the stirring of the slurry, and improving the purity of the slurry.

[0038] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
