TECHNICAL FIELD
[0001] The utility model belongs to the field of slurry mixing of investment casting, and particularly relates to a slurry barrel mixing structure with lifting adjustment and cooling function. BACKGROUND
[0002] In the field of investment casting, a slurry barrel is usually used to dip slurry on the surface of a wax mold to form a refractory coating. In order to ensure uniformity of the slurry and avoid sedimentation or stratification, the slurry usually needs to be continuously stirred. In order to facilitate the wax mold being put into the slurry barrel (not affected by the stirring structure), the slurry barrel and its stirring structure are usually different from the form of the traditional container being fixed and the paddle being continuously rotated for stirring, but the slurry barrel is arranged to be rotated by a motor driving mechanism and the paddle is arranged at the edge of the slurry barrel and in an L shape. The paddle currently equipped in the slurry barrel is generally arranged on one side and the upper part of the paddle is fixed to the top of the outer barrel of the slurry barrel (the outer barrel does not rotate and the inner barrel is driven by the motor), and the lower part of the paddle extends into the inner barrel. The defects of this kind of way are as follows: the paddle has insufficient strength and is easily deformed and damaged when impacted by the slurry; the paddle is designed in a simple rectangular plate shape, has large resistance and poor stirring effect; the height of the paddle in the inner barrel cannot be adjusted, and the stirring effect cannot be adjusted according to the amount of the slurry; a slurry temperature control mechanism is lacking, and the slurry temperature is too high, which easily causes the wax mold to be damaged and the slurry to fail to be hung. SUMMARY

[0004] The technical scheme for solving the above technical problems of the utility model is as follows: a slurry barrel stirring structure with lifting adjustment and cooling function, which comprises an L-shaped stirring paddle composed of a vertical section and a horizontal section located at the lower end of the vertical section, and an outer support frame for fixing and adjusting the lifting of the stirring paddle, the slurry-facing surfaces of the vertical section and the horizontal section are provided with inclined surfaces for dispersing slurry by cutting water with the tip of the inclined surface, the vertical section and the horizontal section are both provided with hollow cavities and are in communication with each other, the upper end of the vertical section is provided with a mounting plate for fixed connection with the top end connecting plate of the outer support frame, the outer support frame is provided with a cooling liquid inlet pipe and a cooling liquid outlet pipe, the cooling liquid inlet pipe and the cooling liquid outlet pipe both extend into the hollow cavity through the through hole opened in the mounting plate, and the outer support frame is provided with a lifting adjustment mechanism for adjusting the height of the connecting plate from the ground.
[0005] On the basis of the above technical scheme, the utility model can also be improved as follows.
[0006] Further, the lifting adjusting mechanism is a ball screw lifter, comprising a screw rod, a gear box and a worm, the worm is located in the middle of the gear box and is in transmission connection with the screw rod through gears, two ends of the worm extend out of the gear box, one end is connected with a hand wheel, and the other end is adaptively connected with an output end of a motor or a hand drill, and the upper end of the screw rod is fixedly connected with the connecting plate.
[0007] Further, the cooling liquid inlet pipe and the cooling liquid outlet pipe are fixed on the outer support frame through a clamp.
[0008] Further, the cooling liquid inlet pipe extends to one end of the horizontal section close to the center of the pulp barrel after extending into the hollow cavity, and the cooling liquid outlet pipe is located at the upper part of the vertical section after extending into the hollow cavity.
[0009] Further, the included angle between the pulp-approaching surface of the vertical section and the corresponding back pulp surface is 45 degrees.
[0010] Further, the stirring paddle has two and is distributed in the pulp barrel in a central symmetry with each other, the horizontal section of the two stirring paddles is fixed with a horizontally extending paddle baffle, the two paddle baffles are fixedly connected through a connecting piece, and the included angle between the paddle baffle and the pulp-approaching side of the corresponding horizontal section is obtuse.
[0011] Further, the two paddle baffles are in the same vertical plane, and the connecting piece is provided with a waist-shaped connecting hole for connecting the paddle baffles.
[0012] Further, the outer support frame comprises a base plate and a vertical support plate, the vertical support plate is fixed on the base plate, and the lifting adjusting mechanism is arranged on the vertical support plate.

[0014] Further, the back pulp surface of the vertical section is provided with a plurality of vertical reinforcing ribs, and the stirring paddle is made of stainless steel.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] The mixing blades of the slurry tank mixing structure provided by this utility model have inclined surfaces on the slurry-facing side of both the vertical and horizontal sections. During mixing and water cutting, this reduces resistance and more effectively disperses the fluid, significantly improving mixing efficiency. The vertical and horizontal sections have interconnected hollow cavities, allowing coolant to fill both sections and enhancing the cooling effect on the slurry. The height of the mixing blades can be adjusted via the lifting and adjusting structure of the external support frame, allowing for adjustments based on the slurry height in the tank and ensuring good mixing performance. A blade baffle extending towards the center of the tank is also provided at the end of the horizontal section away from the vertical section, effectively preventing slurry accumulation at the mixing center. When the two mixing blades are centrally symmetrically distributed on both radial sides of the tank, the blade baffle connects the two blades, not only enhancing the mixing effect but also effectively increasing the blades' resistance to deformation and preventing scraping against the tank wall.

[0030] It should be noted that, as shown in Figure 1 and 2 The slope surface is part of the pulp facing, and the pulp facing is not entirely inclined, the slope bottom corner cuts water, and the slope top corner has an extension part perpendicular to the vertical part, so as to increase the area of the pulp facing and enhance the stirring effect.

[0032] Need to explain, can manually rotate hand wheel or through electric drill to connect worm one end to adjust when lifting adjustment.
[0033] In an embodiment of the utility model, cooling liquid inlet pipe 8 and cooling liquid outlet pipe 9 are fixed on outer support frame 3 by clamp 14.
[0034] Need to explain, cooling liquid inlet pipe and cooling tank outlet pipe are communicated with cooling liquid storage equipment through pumping mechanism.
[0035] In an embodiment of the utility model, cooling liquid inlet pipe 8 extends to the end of horizontal section 2 close to the center of pulp barrel after extending into hollow cavity, and cooling liquid outlet pipe 9 is located at the upper part of vertical section 1 after extending into hollow cavity.
[0036] It can be understood that the cooling liquid inlet pipe extends into the deep part of the horizontal section, which can ensure that the cooling liquid can smoothly enter the hollow cavity of the horizontal section first, and then flow into the hollow cavity of the vertical section from bottom to top, to ensure better cooling effect.
[0037] In an embodiment of the utility model, the included angle between the pulp-facing surface 4 of the vertical section 1 and the corresponding back pulp surface 5 is 45 degrees.

[0044] In an embodiment of the present application, the back pulp surface 5 of the vertical section 1 is provided with a plurality of vertical reinforcing ribs, and the stirring paddle is made of stainless steel.
[0045] It should be noted that the reinforcing rib can effectively enhance the rigidity of the vertical section of the stirring paddle (because the vertical section is longer than the horizontal section, it is easy to deform under the blocking action of the pulp liquid), and after the reinforcing rib is arranged, the resistance of the vertical section to deformation is significantly increased.
