As a further scheme of the invention, the stirring frames 16 are symmetrically arranged in a rectangular shape, and the double stirring frames 16 can not only increase the stirring and cleaning efficiency, but also improve the stability of the equipment during rotation.
As a further aspect of the present invention, the feed inlet 4 is provided with a one-way flap, which is provided to prevent the raw material from flying out of the feed inlet 4 during stirring.
The invention adjusts the relative position of the through hole on the sphere center and the open hole on the sphere shell through the matching of the first bevel gear, the second bevel gear provided with incomplete teeth and the torsion spring, and further controls high-pressure water flow and high-pressure air flow to respectively enter the driving shaft, so as to achieve the purpose of stirring or cleaning.
The working principle is as follows: when the reversing valve is used, high-pressure water flow needs to be connected to the left side of the reversing valve, and high-pressure air flow needs to be connected to the right side of the reversing valve
When the ball center 18 is in a vertical state at the initial position, raw materials to be processed are put into the stirring box through the feeding hole 4, then the motor 1 is started, the motor 1 rotates to drive the driving shaft 2 to rotate, the driving rotation drives the second bevel gear 10 to rotate through the first bevel gear 9 fixedly connected with the driving shaft, the second bevel gear 10 rotates to drive the ball center 18 to rotate through the rotating shaft 11 fixedly connected with the second bevel gear 10, and because the second bevel gear 10 is an incomplete gear, when the first bevel gear 9 drives the second bevel gear 10 to rotate for 45 degrees, the second bevel gear 10 cannot be continuously driven to rotate continuously after the gear teeth of the second bevel gear are completely meshed, and because a torsion spring is arranged between the second bevel gear 10 and the valve body 12, the second bevel gear 10 can keep a state after rotating for 45 degrees under the action of the torsion spring and the first bevel gear 9;
at this time, the high-pressure air flow enters the second cavity 20 through the through hole on the left side of the splitter plate 12-1 arranged on the upper part of the partition plate 13, but the driving shaft 2 continues to rotate, and when the second cavity 20 rotates to the right side, the high-pressure air flow is communicated with the third semicircular groove 12-2 arranged on the right side of the splitter plate 12-1, and the air flow continues to enter the second cavity 20 along the third semicircular groove 12-2 communicated with the through hole on the left side of the splitter plate 12-1, and the process is repeated, so that sufficient air flow is ensured in the driving shaft 2 (because the distance between the second cavity 20 and the first cavity 19 is farther from the axis of the driving shaft 2, and the through holes on the splitter plate 12-1 are respectively corresponding to the two cavities, when the two cavities rotate relative to the spherical shell 17, the first cavity 19 can only be communicated with the through hole on the right side of the splitter plate 12-1 all the time, and the second cavity 20 can only be communicated with the through hole on the left side of the splitter plate 12-1 all the time);
the high-pressure air will flow to the left-side stirring frame 16 through the first cavity 19 and to the right-side stirring frame 16 through the second semicircular groove 26, and then the air will flow out into the stirring box through the air holes on the stirring frame 16, so as to assist the stirring frame 16 to further homogenize the raw materials;
after the raw materials are uniformly stirred, opening a bottom discharge port 7, discharging the raw materials out of a stirring box under the drive of airflow, then closing the discharge port 7, and opening a water discharge port 8 to enable a motor 1 to rotate;
the motor 1 rotates to drive the driving shaft 2 to rotate, similarly, the driving shaft 2 drives the second bevel gear 10 to rotate through the first bevel gear 9 fixedly connected with the driving shaft, then the second bevel gear 10 drives the sphere center 18 to rotate through the rotating shaft 11, and because the second bevel gear 10 is an incomplete gear, the second bevel gear 10 can only rotate 90 degrees under the drive of the first bevel gear 9, and similarly, under the action of the torsion spring, the second bevel gear 10 can keep a state after rotating 90 degrees;
at this time, the ball center 18 is rotated 90 degrees under the driving of the second bevel gear 10, so that the through hole in the ball center 18 is matched with the through hole on the right side of the ball shell 17, so that the left side high pressure water flow is communicated with the right chamber of the valve body 12, furthermore, when the first cavity 19 rotates relative to the valve body 12, when the first cavity 19 rotates to the left side, the first cavity 19 is communicated with the diversion hole 13-1 formed on the partition plate 13, so that the water flow continues to enter the first cavity 19 along the diversion hole 13-1 communicated with the right chamber of the valve body 12, because the first cavity 19 is closer to the axis of the driving shaft 2 than the second cavity 20, when the first cavity 19 rotates relative to the valve body 12, the first cavity 19 is communicated with the folding hose 24 because of being dislocated with the through hole of the diversion plate 12-1 on the left side in the valve body 12, because the first cavity 19 is communicated with the diversion hole 13-1 on the partition plate 13, so as to ensure that the first cavity 19 can always be communicated with the water inlet, further high pressure water flow is communicated with the folding hose 24 through the first cavity 19 and the first cavity 16 communicated with the stirring tank 16 through the second cavity 16, because the second cavity 16 is provided with the second cavity 16, the second cavity 16 is communicated with the stirring tank 16, and the stirring tank 16, when the stirring tank 16 moves downwards, so that the water flow cannot enter the second cavity;
when the washing is finished, the motor 1 is turned off, due to the action of the torsion spring, when the torsion spring recovers to the initial state, the torsion spring can drive the second bevel gear 10 to rotate for 45 degrees, at the moment, the sphere center 18 can be vertical again, no high-pressure water flow enters the driving shaft 2, the piston 23 can be pulled back to the initial position under the action of the spring 25, redundant water in the stirring frames 16 on the two sides can also flow onto the bottom plate 6 through the through groove 21 communicated with the auxiliary cavity 20-1 and then flows out through the water outlet 8, and then the water outlet 8 is closed.
