In this embodiment, the size of the opening of the solid phase outlet 1402 for the solid phase to pass through is positively correlated to the amount of the pressing force of the solid phase against the barrier member 14. Since the solid phase moves upward into the solid phase containing space continuously, the speed of the solid phase passing through the solid phase outlet 1402 is slower than the speed of the solid phase moving upward along the rotary drum 13, and the solid phase is easily blocked when being accumulated in the solid phase containing space continuously. Therefore, the size of the opening of the solid phase outlet 1402 for the solid phase to pass through is positively correlated with the size of the pressing force of the solid phase on the blocking member 14, so that the size of the opening of the solid phase outlet 1402 for the solid phase to pass through can be changed according to the difference of the pressing force of the solid phase on the blocking member 14, and when the solid phase is continuously accumulated in the accommodating space, the pressing force of the solid phase on the blocking member 14 can be gradually enhanced, so that the opening of the solid phase outlet 1402 for the solid phase to pass through is increased, the solid phase passes through the solid phase outlet 1402, and the blocking situation can be prevented.

Because the feed hopper 12 is located at the center of the upper shell 5 and the conical cap 15 is located at the center of the bottom of the rotary drum 13, the axial line of the feed hopper 12 can be coincided with the axial line of the conical cap 15 only by coinciding the axial line of the upper shell 5 with the axial line of the lower shell 2, and in this state, the material poured from the feed hopper 12 falls into the top of the conical cap 15 and is uniformly dispersed around the bottom of the rotary drum 13, and the situation that the material directly falls onto the inner wall of the rotary drum 13 cannot occur. Because the upper shell 5 is movably covered outside the lower shell 2, the upper shell 5 can move in the horizontal direction under the action of the elastic extrusion mechanisms 7, so that the vertical distances from the inner wall of the upper shell 5 to the inner wall of the lower shell 2 are the same, and the purpose of overlapping the axial lead of the upper shell 5 and the axial lead of the lower shell 2 is realized.

In a preferred embodiment, the elastic pressing mechanism 7 includes a base 701 fixedly connected to an inner wall of the upper housing 5, a cavity 702 is disposed inside the base 701, a push rod 704 is slidably inserted into the cavity 702, a spring 703 is connected between one end of the push rod 704 and the cavity 702, a groove 705 is disposed at the other end of the push rod 704, a pressing bead 706 is disposed in the groove 705, the pressing bead 706 partially protrudes outside the groove 705 and presses against an outer wall of the lower housing 2, the pressing bead 706 is in rolling connection with an outer wall of the lower housing 2, and the pressing mechanism 7 does not hinder the rotation of the upper housing 5 due to the rolling connection between the pressing bead 706 and the outer wall of the lower housing 2. When the pressing balls 706 are pressed against the outer wall of the lower shell 2, the springs 703 are in a compressed state, because the friction force between the balls 603 and the annular plate 3 is small, the springs 703 can push the upper shell 5 to move in the horizontal direction, and when the stress of each spring 703 is balanced, the length of each spring is the same, and at the moment, the upper shell 5 is in a stable state, so that the axial lead of the upper shell 5 can be coincided with the axial lead of the lower shell 2;

meanwhile, under the action of each elastic extrusion mechanism 7, the upper shell 5 can be limited, so that the upper shell 5 is prevented from moving in the horizontal direction when the material is poured, once the upper shell 5 moves, the axial line of the feeding hopper 12 is staggered with the axial line of the conical cap 15, and the poured material falls onto the inner wall of the rotary drum 13, so that the technical problems are caused; and the inner wall of the upper case 5 can be prevented from colliding with the outer wall of the lower case 2.

Wherein, when spring 703 was compressed to the limit state, press the pearl 706 still to be located the outside of pedestal 701, guarantee that pedestal 701 can not contact with the outer wall of lower casing 2 all the time, prevent to appear scraping.

In order to ensure that the pressing bead 706 cannot be separated from the groove 705 by itself, a rubber ring 707 is fixedly bonded in the groove 705, the inner diameter of the rubber ring 707 is smaller than the diameter of the pressing bead 706, so that the pressing bead 706 is not easy to separate from the groove 705, and meanwhile, the pressing bead 706 can penetrate through the rubber ring 707 by utilizing the elastic force of the rubber ring 707 when acting force is applied to the pressing bead 706.

In this embodiment, when the upper housing 5 is disassembled, the spring 703 is in a natural state, at this time, the diameter of an inscribed circle formed by the plurality of elastic pressing mechanisms 7 is smaller than the outer diameter of the lower housing 2, and is larger than the outer diameter of the top of the inclined portion 201, because the outer diameter of the inclined portion 201 is gradually decreased from bottom to top, when reaching the top, the outer diameter of the inclined portion 201 is the smallest, and by utilizing the inclined design of the inclined portion 201, when the upper housing 5 is covered on the lower housing 2, each elastic pressing mechanism 7 can smoothly pass through the top of the lower housing 2, and is not easily blocked by the top of the lower housing 2, thereby more conveniently completing the installation of the upper housing 5.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
