SUMMARY

[0005] The purpose of the present application is to provide a multi-shaft grinding machine anti-dead material multi-point type circulating discharge system, which has the effect of improving the material discharge rate of the sand mill barrel.

[0006] To achieve the above purpose, the present application provides the following technical scheme:

[0007] The multi-shaft grinder prevents material from being dead and a multi-point circulating discharge system comprises a base, a leakage hole is formed in the bottom surface of the base, a leakage cylinder is arranged in the leakage hole, a guide block is arranged on the bottom surface of the base, the guide block is arranged along the side wall of the base, one side of the guide block away from the bottom surface of the base is provided with a guide surface pointing to the center of the bottom surface of the base, a discharge port is formed in one end of the leakage cylinder away from the guide pipe, the discharge port is located in the coverage range of the guide surface, the height of the discharge port is the same as that of the guide surface, a cover and a filter cover on the discharge port are arranged on the leakage cylinder, a dead angle hole is formed in the side wall of the leakage cylinder, and the bottom wall of the base is located in the span range of the dead angle hole.

[0008] By adopting the above technical scheme, after the material grinding is completed, the material falls in the direction of the base, and the material falls on the guide surface and does not fall in the four corners between the side wall and the bottom wall of the base, and under the guidance of the guide surface, the material falls back into the leakage hole, and the material falling on the bottom wall of the base is all in the rotating coverage range of the rubber stick rod, as long as the stirring rod is started again, the material sinking into the base can be suspended again and falls on the guide surface, so that the material in the barrel cannot be stuck in the dead angle, thereby improving the discharge filtering effect of the sand mill barrel.

[0009] Further, one end of the leakage cylinder away from the discharge port is provided with a material collecting cover, the material collecting cover is arranged in an inverted conical shape, and the end of the material collecting cover away from the leakage cylinder is connected to the guide pipe.

[0010] By adopting the above technical scheme, the material collecting cover is arranged in an inverted conical shape, so that after the material falls into the material collecting cover, the material does not deposit at the edges and corners of the leakage cylinder, but flows into the guide pipe along the material collecting cover, thereby further improving the discharge rate of the material in the barrel.

[0011] Further, a filter cylinder is fixedly arranged in the leakage cylinder, and the filter cover covers one end of the filter cylinder away from the material collecting cover.

[0012] By adopting the above technical scheme, the filter cylinder can place the large particles of the material which is not fully ground to discharge the barrel, and the filter cylinder can provide a placement point for the filter cover, thereby improving the stability of the placement of the filter cover on the filter cylinder.

[0013] Further, the filter cover is provided with a lap edge lapping on the side wall of the leakage cylinder.

[0014] By adopting the above technical scheme, when the operator needs to cover the filter cover on the leakage cylinder, the operator only needs to place the filter cover on the end surface of the leakage cylinder, and then lap the lap edge on the end surface of the leakage cylinder, thereby preliminarily fixing the filter cover on the leakage cylinder.

[0016] By adopting the above technical scheme, the storage surface can hold a large amount of material sliding down the guide surface, and the material held in the buffer surface will not fall onto the bottom wall of the base, thereby further improving the leakage efficiency of the sand mill.

[0017] Further, the leakage holes are uniformly distributed along the periphery of the base.

[0018] By adopting the above technical scheme, the plurality of leakage holes makes the material in the barrel leak more dispersed, and on the other hand, the discharge speed of the plurality of leakage holes will also become faster.

[0022] By adopting the above technical scheme, when the operator needs to fix the guide pipe on the guide pipe, the guide pipe is only needed to be sleeved on the guide pipe, and then the throat clamp is sleeved on the outside wall of the guide pipe, and the throat clamp is arranged corresponding to the connecting groove, thereby fixing the guide pipe on the guide pipe.

[0023] Further, a connecting cylinder is arranged in the guide pipe away from the guide pipe, a connecting sleeve is rotatably arranged at one end of the connecting head away from the collection box, and the connecting sleeve and the connecting cylinder are in threaded cooperation.

[0024] By adopting the above technical scheme, when the guide pipe needs to be fixed on the collection box, the connecting cylinder is only needed to be arranged in the connecting sleeve, and then the connecting cylinder is abutted on the connecting head by rotating the connecting sleeve, thereby facilitating the sealing connection of the guide pipe on the collection box.

[0025] Furthermore, a negative pressure pipe is connected to the side of the collection box away from the connector. The end of the negative pressure pipe away from the collection box is connected to a negative pressure device. A guide surface is provided on the side of the collection box near the placement rack. The guide surface is oriented towards the negative pressure pipe, and the height of the end of the guide surface pointing towards the negative pressure pipe is lower than the height of the other end.
