[0032] In actual use, the movement of the piston rod 3.2 towards the shaft rotating pipe 2.1 is the extension movement, and the movement of the piston rod 3.2 away from the shaft rotating pipe 2.1 is the extension movement;

[0035] In still another embodiment of the present application, the kettle body 1 is provided with a slide rail structure 4 on the inner bottom wall of the kettle body 1, the slide rail structure 4 is slidably fitted with a sliding block 5 fixed with the piston rod 3.2, and the sliding block 5 drives the piston rod 3.2 to reciprocate in the cross pipe 3.1 during the movement along the slide rail structure 4, further, the slide rail structure 4 is a ring rail structure connected at the head and tail, or the slide rail structure 4 is a ring groove structure connected at the head and tail, and the entire slide rail structure 4 is approximately in the shape of a peach heart, preferably, the sliding block 5 is rotatably provided with a slide fork 17 matched with the slide rail structure 4 at the bottom end, and a plurality of pulleys reducing the sliding resistance are movably arranged on the slide fork 17, and the sliding block 5 drives the piston rod 3.2 to reciprocate along the axis direction of the cross pipe 3.1 during the movement on the slide rail structure 4, thereby continuously providing driving force for the linear reciprocating piston movement of the piston rod 3.2.

[0038] In another embodiment provided by the application, the one-way discharge unit 3.4 includes a discharge port 9 opened in the side wall of the horizontal pipe 3.1 insertion end and a liquid drain pipe 10 communicated in the side wall of the horizontal pipe 3.1, the horizontal pipe 3.1 is communicated with the shaft rotating pipe 2.1 through the discharge port 9, the discharge port 9 is located at the lower position of the horizontal pipe 3.1, the discharge port 9 and the liquid drain pipe 10 communication position are installed with the blocking block 11 matched with the inner wall of the horizontal pipe 3.1, the liquid drain pipe 10 communication position is the position of the liquid drain pipe 10 communicated and docked on the horizontal pipe 3.1, the end of the liquid drain pipe 10 is flush with the pipe wall of the horizontal pipe 3.1, the liquid drain pipe 10 is fixed with a filter layer 12 at the communication end, the surface of the filter layer 12 is flush with the inner wall of the horizontal pipe 3.1, and a one-way check valve is also installed in the liquid drain pipe 10 to prevent external air from entering the horizontal pipe 3.1 through the liquid drain pipe 10;

[0039] In actual use, when the piston rod 3.2 occurs the extension movement, the contents in the horizontal pipe 3.1 are filtered through the filter layer 12 under pressure, the filter layer 12 can filter and intercept the sediment in the kettle body 1, and when the piston rod 3.2 occurs the extension movement, the liquid in the horizontal pipe 3.1 is filtered through the filter layer 12 and discharged out of the kettle body 1 through the liquid drain pipe 10, and the filtered sediment is located in the horizontal pipe 3.1.

[0040] In another embodiment provided by the application, the horizontal pipe 3.1 and the blocking block 11 are provided with a locking unit 13, which can lock the position of the blocking block 11 in the horizontal pipe 3.1 in the locked state, and the blocking block 11 can slide in the horizontal pipe 3.1 under the action of the piston rod 3.2 in the unlocked state;

[0041] The locking unit 13 includes a locking tongue unit 14 movably installed on the blocking block 11, and a locking groove structure 15 opened in the inner wall of the horizontal pipe 3.1, and the end of the piston rod 3.2 is provided with a trigger unit 16 capable of switching the locking tongue unit 14;

[0042] The lock tongue unit 14 comprises a cavity opening 14.1 formed on the side surface of the blocking block 11, a rotating shaft 14.2 is rotatably arranged in the cavity opening 14.1, the axis of the rotating shaft 14.2 is parallel to the axis of the horizontal pipe 3.1, one end of the rotating shaft 14.2 extends out of the cavity opening 14.1, the extending end of the rotating shaft 14.2 is located between the piston rod 3.2 and the blocking block 11, a branch rod 14.4 is vertically fixed on the rod body side of the extending end of the rotating shaft 14.2, the lock tongue rod 14.3 is arranged in the cavity opening 14.1, one end of the lock tongue rod 14.3 is vertically fixed on the rotating shaft 14.2, and the other end of the lock tongue rod 14.3 is adapted to be locked on the lock slot structure 15;

[0043] The lock slot structure 15 comprises a long rail slot 15.1, the length direction of the long rail slot 15.1 is parallel to the axis of the horizontal pipe 3.1, a branch card slot 15.2 is formed on the side surface of the long rail slot 15.1, the length direction of the branch card slot 15.2 is perpendicular to the length direction of the long rail slot 15.1, when the end of the lock tongue rod 14.3 is located in the branch card slot 15.2, the lock unit 13 is in the locked state, and when the end of the lock tongue rod 14.3 is located in the long rail slot 15.1, the lock unit 13 is in the unlocked state;

[0044] The trigger unit 16 comprises a protruding block 16.1 fixed on the end of the piston rod 3.2, and an inclined slot opening 16.2 is formed in the protruding block 16.1, and the slot end of the inclined slot opening 16.2 is in an open state;

[0045] Further, the trigger unit 16 can switch the lock unit 13 to the unlocked state in the stroke of the piston rod 3.2 in the extension movement, and the trigger unit 16 can switch the lock unit 13 to the locked state in the stroke of the piston rod 3.2 in the extension movement;

[0046] In actual use, when the content in the horizontal pipe 3.1 is filtered by the filter layer 12 under pressure, the protruding block 16.1 also moves towards the blocking block 11 synchronously with the piston rod 3.2, so that the branch rod 14.4 and the inclined slot opening 16.2 are slidably connected, the branch rod 14.4 relatively slides on the inclined slot opening 16.2, and in the relative sliding process, the branch rod 14.4 is subjected to a component force generated by the side slot wall of the inclined slot opening 16.2, so that the branch rod 14.4 drives the rotating shaft 14.2 to positively deflect, and then the lock tongue rod 14.3 is deviated from the branch card slot 15.2 to the long rail slot 15.1, at this time, the lock unit 13 is switched from the locked state to the unlocked state;

[0047] Thus, as the piston rod 3.2 continues to move in, since the lock unit 13 has been in the unlocked state, and at this time the sediment is also filtered, so the blocking block 11 is moved by the pushing force of the piston rod 3.2 in the direction of the insertion end of the horizontal pipe 3.1, and at the same time the end of the lock tongue rod 14.3 slides along the long rail slot 15.1 away from the split card slot 15.2, and the piston rod 3.2 also passes through the filter layer 12 in the process, thereby removing the sediment on the surface of the filter layer 12, until the blocking block 11 passes through the discharge port 9 and contacts the inner wall of the shaft rotating pipe 2.1, at which time the filtered sediment enters the shaft rotating pipe 2.1 through the discharge port 9, and then is discharged through the bottom end of the shaft rotating pipe 2.1;

[0048] When the piston rod 3.2 moves out, for the same reason, the other side of the inclined slot 16.2 at this time generates a component force on the branch rod 14.4, so that the branch rod 14.4 drives the rotating shaft 14.2 to deflect in the opposite direction. Since the position of the blocking block 11 changes after being pushed, the lock tongue rod 14.3 installed on the blocking block 11 also moves, so that the split card slot 15.2 is out of the deflection track of the lock tongue rod 14.3. Therefore, the deflection of the lock tongue rod 14.3 on the long rail slot 15.1 is limited, which further causes the rotating shaft 14.2 to also be unable to rotate, and the branch rod 14.4 is stuck in the inclined slot 16.2 and cannot be separated from the inclined slot 16.2;

[0049] Therefore, during the extension movement of the piston rod 3.2, the piston rod 3.2 drives the blocking block 11 to move away from the insertion end of the horizontal pipe 3.1 under the connection of the trigger unit 16 and the lock tongue unit 14. At the same time, the lock tongue rod 14.3 also linearly slides on the slot wall of the long rail slot 15.1. When the lock tongue rod 14.3 reaches the position of the split card slot 15.2, the lock tongue rod 14.3 can slide from the long rail slot 15.1 into the split card slot 15.2 at this time, so that the lock unit 13 switches to the locked state, and the branch rod 14.4 is separated from the inclined slot 16.2. When the piston rod 3.2 continues to move out, the blocking block 11 no longer moves, and the blocking block 11 is in the locked state of the lock unit 13, so that the blocking block 11 remains stationary during the pressure filtration of the contents;

[0050] In short, the blocking block 11 has two positions in the horizontal pipe 3.1, the first position when the contents are being filtered, and the second position when the filtered contents form sediment, which is discharged through the discharge port 9. When the blocking block 11 is in the first position, the lock unit 13 is in the locked state, and the lock unit 13 can lock and position the blocking block 11, thereby preventing the blocking block 11 from moving;

[0051] In the course of the piston rod 3.2 performing the extension movement, the content in the cross tube 3.1 is actually subjected to pressure filtration, when the piston rod 3.2 is deep into the end close to the blocking block 11, at this time, the pressure filtration process is close to the end, so that the piston rod 3.2 triggers the unlocking of the lock split unit 13 through the triggering unit 16, so that the blocking block 11 can be pushed by the extension movement of the piston rod 3.2, so that the blocking block 11 is from the first position to the second position, and the precipitate after pressure filtration is discharged through the discharge port 9 and the bottom end of the shaft rotating tube 2.1;

[0052] In the course of the piston rod 3.2 performing the extension movement, the content in the cross tube 3.1 is actually subjected to pressure filtration, when the piston rod 3.2 is deep into the end close to the blocking block 11, at this time, the pressure filtration process is close to the end, so that the piston rod 3.2 triggers the unlocking of the lock split unit 13 through the triggering unit 16, so that the blocking block 11 can be pushed by the extension movement of the piston rod 3.2, so that the blocking block 11 is from the first position to the second position, and the precipitate after pressure filtration is discharged through the discharge port 9 and the bottom end of the shaft rotating tube 2.1;

[0053] The whole process is simple to operate, and the product in the kettle body 1 can be discharged from the kettle body 1 in time and continuously, and the discharged product also realizes solid-liquid separation, reduces the water content of the precipitate, and facilitates the subsequent process.

[0054] The above only describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of the claims of the present application.
