As more and more slag is present on the first filter plate 222, under the action of the liquid sucked into the accommodating chamber 220, the resistance of the first filter plate 222 to the slag is greater and greater, and the first filter plate 222 moves in the liquid inlet pipe 221 in the same direction as the liquid flowing direction and in the axial direction against the acting force of the first elastic member 226. Meanwhile, the restriction block 224 on the first filter plate 222 moves in synchronization with the first filter plate 222, and the restriction block 224 protrudes through the through-holes on the grating plate 223. It should be noted that, when the first filter plate 222 has more accumulated slag, it is indicated that the first filter plate 222 has serious blocking, the greater the resistance of the first filter plate 222 to the slag, the longer the first filter plate 222 moves, so that the longer the distance of the flow-limiting block 224 extending out of the through hole, the larger the gap between the flow-limiting block 224 and the through hole; when the first filter plate 222 has less accumulation of slag, it means that the first filter plate 222 is almost not blocked, the first filter plate 222 is almost not blocked by slag, the shorter the distance the first filter plate 222 moves, the shorter the distance the flow limiting block 224 extends out of the through hole, the smaller the gap between the flow limiting block 224 and the through hole, but the liquid can enter the containing cavity 220 through the liquid inlet pipeline 221.
When the piston plate 203 moves to the extreme position, i.e., when the volume of the receiving chamber 220 reaches a maximum, no more liquid enters the receiving chamber 220, and at this time, the first filter plate 222 is not moved and is limited by the limiting assembly 240, i.e., the first filter plate 222 stops moving. The first filter plate 222 stops moving, indicating that the position of the restrictor 224 extending out of the through-hole is no longer changed, that is, the gap between the restrictor 224 and the through-hole is no longer changed. The piston plate 203 moves leftward, the volume of the receiving chamber 220 is reduced, and the liquid in the receiving chamber 220 is squeezed, wherein a part of the liquid is discharged to the outside through the drain pipe 210, and the other part of the liquid flows through the first filter plate 222 through the gap between the flow restricting block 224 and the through hole and returns to the inside of the housing 100. It should be noted that, a portion of the liquid flowing through the first filter plate 222 has a certain impact force under the extrusion of the accommodating cavity 220, so that the first filter plate 222 can be backwashed, and the residue on the first filter plate 222 can be washed away. When the gap between the flow restriction block 224 and the through hole is larger, more liquid can flow through to flush the first filter plate 222; when the gap between the flow limiting block 224 and the through hole is smaller, less liquid can flow through to wash the first filter plate 222, so that the water flow is adjusted according to the blocking degree of the first filter plate 222, and the washing force for washing the first filter plate 222 is changed.
It will be appreciated that the greater the degree of clogging of the first filter plate 222, the greater the water flow required to flush it, and the lesser the degree of clogging of the first filter plate 222, the lesser the water flow required to flush it. When the liquid enters the accommodating cavity 220 to fill the accommodating cavity 220 with the liquid, the gap between the flow limiting block 224 and the through hole is adjusted according to the blocking degree of the first filter plate 222, namely, when the blocking degree of the first filter plate 222 is larger, the gap between the flow limiting block 224 and the through hole is larger; the smaller the clogging degree of the first filter plate 222, the smaller the gap between the restrictor 224 and the through hole. And so that the water flow through the gap flushes the first filter plate 222 as liquid is discharged. The first filter plate 222 is washed once every time the piston plate 203 reciprocates and stretches, so that the first filter plate 222 can keep a clean state, the filtering effect of the first filter plate 222 is improved, and the working efficiency of the traditional Chinese medicine effective component extracting device is improved.
Specifically, the limiting assembly 240 is configured to limit the position of the first filter plate 222, when the piston plate 203 moves rightward to increase the volume of the accommodating chamber 220 to absorb water, the first filter plate 222 can move to adjust the gap between the limiting block 224 and the through hole, and when the accommodating chamber 220 absorbs liquid, the first filter plate 222 can only move along the flowing direction of the liquid under the action of the limiting assembly 240 and cannot move in the direction opposite to the flowing direction of the liquid. When the piston plate 203 moves to the extreme position, i.e., the volume of the receiving chamber 220 is maximized, the first filter plate 222 stops moving when the piston plate 203 moves to the rightmost side of the receiving cylinder 201, and the limiting assembly 240 limits the movement of the first filter plate 222. The piston plate 203 starts to move to the left to squeeze the liquid in the accommodating chamber 220, the first filter plate 222 is limited by the limiting assembly 240, that is, the size of the gap between the limiting block 224 and the through hole is kept unchanged until the first filter plate 222 is not limited by the limiting assembly 240 after the liquid is discharged, and the first filter plate 222 is reset under the action of the first elastic member 226.
As shown in fig. 9 and 12, the limiting component 240 includes a limiting block 241, a rack is disposed on the limiting block 241, the rack can move up and down on the limiting block 241, a compression spring is disposed below the rack, and the compression spring is in an original length state in an initial state. The wedge block is fixedly arranged at one end, close to the limiting groove 243, of the first filter plate 222, the wedge block extends into the limiting groove 243, the inclined surface of the wedge block is in contact with the rack of the limiting block 241, a groove is formed between adjacent teeth of the rack, the wedge block is inserted into the groove, and the rack and the wedge block are matched to allow the first filter plate 222 to move in the liquid inlet pipeline 221 along the liquid inlet direction and prevent the first filter plate 222 from moving in the direction opposite to the liquid inlet direction. When the first filter plate 222 moves along the liquid inlet direction against the acting force of the first elastic member 226, the inclined surface of the wedge block contacts with the rack of the limiting block 241, and the wedge block enables the rack of the limiting block 241 to move downwards, so that the wedge block enters into the groove of the rack. The first filter plate 222 continues to move, the wedge block passes through the plurality of grooves, and when the first filter plate 222 moves to a preset position, the first filter plate 222 is positioned in the groove corresponding to the preset position on the rack, so that the first filter plate 222 is limited, and when the accommodating cavity 220 is drained, the position of the first filter plate 222 is unchanged, namely, the gap between the flow limiting block 224 and the through hole is unchanged.
Specifically, as shown in fig. 6, 9 and 12, a limiting groove 243 is formed in the inner wall of the liquid inlet pipe 221, the limiting groove 243 extends axially along the inner wall of the liquid inlet pipe 221, and the limiting block 241 is slidably disposed in the limiting groove 243, that is, the limiting block 241 can slide in the limiting groove 243 along the circumferential direction of the liquid inlet pipe 221. The sliding of the stopper 241 within the limiting groove 243 can cause the racks of the stopper 241 to contact or disengage the wedge blocks on the first filter plate 222. The limiting groove 243 is internally provided with a second elastic piece 227, one end of the second elastic piece 227 is fixedly connected in the limiting groove 243, and the other end of the second elastic piece 227 is fixedly connected on the limiting block 241. The second elastic member 227 is initially in a compressed state, and the stopper 241 is not initially in contact with the wedge block of the first filter plate 222. Specifically, the stopper 241 is provided with a push rod 242, and the push rod 242 extends into the accommodating cavity 220. In the initial state, the piston plate 203 is located at the leftmost side of the accommodating cylinder 201, i.e. when the volume of the accommodating cavity 220 is minimum, the piston plate 203 pushes the push rod 242 so that the stopper 241 compresses the second elastic member 227, the stopper 241 is separated from the wedge-shaped block of the first filter plate 222, the first filter plate 222 is not limited any more, and the first filter plate 222 is reset under the action of the first elastic member 226.
The volume of the accommodating chamber 220 increases, that is, when the piston plate 203 moves to the right, the piston plate 203 is separated from the push rod 242, the limiting block 241 moves circumferentially below the wedge of the first filter plate 222 along the liquid inlet pipe 221 in the limiting groove 243 under the action of the second elastic member 227, and the racks on the limiting block 241 are in contact with the wedge of the first filter plate 222. The limiting block 241 can slide in the limiting groove 243 through the push rod 242 and the second elastic piece 227, so that the first filter plate 222 is limited or separated from the limit.
In a further embodiment, as shown in fig. 12, the flow restricting block 224 and the first filter plate 222 are connected by a telescopic rod 225, the telescopic end of the telescopic rod 225 is fixedly connected with the flow restricting block 224, and the fixed end of the telescopic rod 225 is fixedly connected with the first filter plate 222. The telescopic rod 225 is sleeved with a third elastic piece 228, the third elastic piece 228 can be a tension spring, other elastic elements such as a spring and the like, one end of the third elastic piece 228 is fixedly connected with the current limiting block 224, and the other end of the third elastic piece 228 is fixedly connected with the fixed end of the telescopic rod 225. When the expansion rod 225 is in the shortened state in the initial state, the flow limiting block 224 is located in the through hole of the grid plate 223 in the initial state, and it is to be noted that when the volume of the accommodating cavity 220 is increased and negative pressure is formed in the accommodating cavity 220 to start absorbing water, if the accumulation of slag on the first filter plate 222 is small and almost none, the first filter plate 222 cannot overcome the acting force of the first elastic member 226, at this time, the first filter plate 222 does not move, the liquid passes through the filtering hole of the first filter plate 222 and flows through the gap between the flow limiting block 224 and the grid plate 223, and since the elastic coefficient of the third elastic member 228 is smaller than the elastic coefficient of the first elastic member 226, the acting force of the third elastic member 228 is overcome after the flow limiting block 224 is impacted by the water flow, so that the expansion rod 225 is elongated to move rightward, and the gap between the flow limiting block 224 and the through hole of the grid plate 223 is increased, so that the liquid can smoothly pass through without affecting the water absorption of the accommodating cavity 220.
In a further embodiment, as shown in fig. 6, a collecting pipe 231 is disposed at the other end of the accommodating cylinder 201, in this embodiment, the collecting pipes 231 are symmetrically disposed on the accommodating cylinder 201, the collecting pipes 231 are all located in the housing 100, one end of each collecting pipe 231 is communicated with the collecting cavity 230, the opening of the other end of each collecting pipe 231 faces the opening of the liquid inlet pipe 221, a second filter plate 232 is disposed at the opening of each collecting pipe 231, the second filter plate 232 is hinged on the opening of each collecting pipe 231, a limiting bar is disposed on each opening, the limiting bar limits the second filter plate 232 to rotate around the outside of the opening of the corresponding collecting pipe 231 in the hinge axis direction, and the second filter plate 232 can only rotate around the inside of the opening of the corresponding collecting pipe 231 in the hinge axis direction to open or close the opening of the corresponding collecting pipe 231.
In the initial state, the piston plate 203 is at the leftmost end, the volume of the accommodating chamber 220 is the smallest, and the volume of the collecting chamber 230 is the largest, and the collecting chamber 230 is filled with liquid in the initial state because the second filter plate 232 is disposed at the opening of the collecting pipe 231 and the collecting pipe 231 is communicated with the collecting chamber 230. When the piston plate 203 moves to the right, the volume of the receiving chamber 220 increases to absorb water, the volume of the collecting chamber 230 decreases to discharge the liquid in the collecting chamber 230, the liquid in the collecting chamber 230 is discharged through the opening of the collecting pipe 231, and the second filter plate 232 at the opening of the collecting pipe 231 is in a closed state under the flow of the liquid discharged in the collecting chamber 230. When the liquid inlet pipeline 221 is used for feeding liquid, the first filter plate 222 is used for blocking the material slag, the material slag is accumulated on the first filter plate 222, when the piston plate 203 moves to the rightmost side, the piston plate 203 starts to move to the left side, the volume of the accommodating cavity 220 is reduced, liquid is discharged, one part of liquid is discharged through the liquid discharge pipeline 210, and the other part of liquid washes the first filter plate 222 through a gap between the flow limiting block 224 and the through hole of the grating plate 223; the volume of the collecting chamber 230 increases, the collecting chamber 230 starts to absorb water through the collecting pipe 231, and the second filter plate 232 at the opening of the collecting pipe 231 rotates around the hinge shaft to the inside to open the opening of the collecting pipe 231 under the flow of the liquid, and the residue washed down on the first filter plate 222 is sucked into the collecting pipe 231 since the opening of the collecting pipe 231 faces the opening of the liquid inlet pipe 221.
When the piston plate 203 moves to the right and the volume of the collection chamber 230 is reduced, the second filter plate 232 at the opening of the collection pipe 231 is closed, so that liquid can only pass through, and slag can not pass through, so that the collection pipe 231 can collect slag, and the reciprocating motion of the piston plate 203 can gradually collect slag in the housing 100, so that slag in the housing 100 is gradually reduced, and the filtering pressure of the first filter plate 222 is reduced.
In a further embodiment, as more and more residues are collected in the collecting pipe 231, the working efficiency of the extracting device for the effective components of the traditional Chinese medicinal materials is affected, and the residues in the collecting pipe 231 need to be treated. A pressing assembly 300 is provided in the collecting chamber 230, and the pressing assembly 300 can discharge the slag in the collecting duct 231 to the outside of the housing 100.
Specifically, as shown in fig. 6, the extrusion assembly 300 includes a filter cartridge 301, one end of the filter cartridge 301 is connected to one end of the accommodating cylinder 201, one end of the filter cartridge 301 is communicated with the collecting chamber 230, the other end of the filter cartridge 301 is provided with a slag discharging port 302, the slag discharging port 302 is connected to the outside, a partition plate 110 is disposed in the casing 100, the partition plate 110 separates the casing 100 into a discharging chamber, the slag discharging port 302 is communicated with the discharging chamber, and the slag is discharged from the outside through the discharging chamber. The filter cylinder 301 is rotatably provided with a packing auger 303, a rotating shaft 321 of the packing auger 303 is rotatably arranged in the filter cylinder 301, and the packing auger 303 is driven by a driving assembly to only move around the axis of the packing auger 303 and cannot move along the axial direction. The blades 304 of the auger 303 are abutted against the inner wall surface of the filter cartridge 301, and a part of the filter residue collected by the collecting pipe 231 enters a position on the filter cartridge 301 connected to the inside of the collecting chamber 230, so that the residue can be conveyed to the residue discharge port 302 when the auger 303 rotates.
In a further embodiment, a plurality of sieve holes are formed on the side surface of the filter cylinder 301 at a position close to the slag discharge opening 302, wherein the sieve holes only allow liquid to pass through and slag cannot pass through. The pitch between the blades 304 of the auger 303 gradually decreases in the conveying direction.
It should be noted that, the interval between the blades 304 of the auger 303 gradually decreases to enable the conveyed slag to be extruded, and meanwhile, the filter cylinder 301 is provided with the sieve pores, so that the liquid extruded from the filter cylinder 301 can be re-introduced into the shell 100, the content of the liquid in the extruded slag is smaller, and the utilization rate of the effective components of the Chinese medicinal materials in the liquid is improved.
Specifically, as shown in fig. 6, 10, 11 and 12, the driving assembly includes a driving sleeve 320 and a stop collar 310, the stop collar 310 is slidably disposed in the collecting cavity 230 through a stop collar 311, the stop collar 311 is fixedly disposed in the collecting cavity 230, the stop collar 311 is multiple and circumferentially distributed, in this embodiment, 4 stop collars are uniformly distributed, 4 protrusions are uniformly disposed on the outer peripheral surface of the stop collar 310, through holes are formed in the protrusions, the axis of the through holes is parallel to the axis of the stop collar 310, the stop collar 311 is slidably inserted in the through holes protruding in the stop collar 310, and the stop collar 310 can slide on the stop collar 311, specifically slide along the axial direction of the stop collar 310. The driving sleeve 320 is arranged on the inner circumferential surface of the limit ring 310 in a unidirectional rotation manner, and the driving sleeve 320 can rotate in a unidirectional manner relative to the limit ring 310, namely, the driving sleeve 320 can only rotate circumferentially in one direction in the limit ring 310 and does not move relatively in the axial direction. The driving sleeve 320 is sleeved on a rotating shaft 321 of the auger 303 extending out of the filter cartridge 301, a thread groove is formed in the rotating shaft 321 of the auger 303, threads are formed in the inner circumferential surface of the driving sleeve 320, and the driving sleeve 320 is in threaded connection with the rotating shaft 321 of the auger 303. When the limit ring 310 axially slides on the limit rod 311, the drive sleeve 320 is synchronously driven to axially move, and because the drive sleeve 320 is connected with the limit ring 310 in a unidirectional rotation manner and the drive sleeve 320 is in threaded connection with the rotating shaft 321, when the limit ring 310 moves in a direction away from the auger 303, the drive sleeve 320 and the limit ring 310 relatively rotate, the drive sleeve 320 and the rotating shaft 321 relatively rotate, namely the rotating shaft 321 is stationary, and the drive sleeve 320 rotates. So that the driving sleeve 320 does not drive the rotating shaft 321 of the auger 303 to rotate; because the driving sleeve 320 is connected with the limit ring 310 in a unidirectional rotation manner, when the limit ring 310 moves towards the direction close to the auger 303, the driving sleeve 320 and the limit ring 310 are relatively static in the circumferential direction, namely, do not rotate relatively, at the moment, the driving sleeve 320 and the rotating shaft 321 rotate relatively, namely, the driving sleeve 320 only moves axially and does not rotate, so that the rotating shaft 321 of the auger 303 rotates, and the auger 303 conveys the slag in the filter cylinder 301 to the slag discharging port 302.
It should be noted that there are many ways to implement unidirectional rotation, which is not described in detail herein, and in this embodiment, unidirectional ratchet and telescopic block 313 are used to implement unidirectional rotation. Specifically, as shown in fig. 8, 11 and 13, a unidirectional ratchet is provided on the outer peripheral surface of the driving sleeve 320, a telescopic block 313 is provided on the inner peripheral surface of the stop collar 310, the telescopic block 313 can extend and retract along the radial direction of the stop collar 310, a spring is provided on one end of the telescopic block 313, the other end of the telescopic block 313 is an inclined surface, the inclined surface of the telescopic block 313 is in contact with the unidirectional ratchet, when the driving sleeve 320 rotates clockwise, as shown in fig. 13, the telescopic block 313 does not limit the driving sleeve 320 to rotate, at this time, the driving sleeve 320 and the stop collar 310 rotate relatively, namely, the stop collar 310 moves in a direction away from the auger 303 so that the driving sleeve 320 and the stop collar 310 rotate relatively; when the driving sleeve 320 wants to rotate anticlockwise, the telescopic block 313 limits the driving sleeve 320 to rotate, at this time, the driving sleeve 320 and the limit ring 310 are relatively stationary, i.e. the limit ring 310 moves towards the direction approaching the auger 303, and the driving sleeve 320 is limited by the limit ring 310 to rotate anticlockwise, so that the auger 303 rotates to convey the slag.
Specifically, the piston plate 203 pushes the stop collar 310 to move in a direction approaching the auger 303, and the stop collar 310 is moved in a direction separating from the auger 303 by the fourth elastic member 312 arranged on the stop lever 311. The fourth elastic piece 312 is sleeved on the limiting rod 311, one end of the fourth elastic piece 312 is fixedly connected with the limiting ring 310, and the other end of the fourth elastic piece 312 is fixedly arranged on the limiting rod 311. Initially, as shown in fig. 6, the fourth elastic member 312 is in an original length state, the piston plate 203 moves rightward, the piston plate 203 abuts against the stopper 310, the piston plate 203 continues to move rightward so that the stopper 310 moves in a direction approaching the auger 303, and the auger 303 rotates the conveying slag. At this time, the fourth elastic member 312 is compressed, and when the piston plate 203 moves to the rightmost side, the piston plate 203 starts to move to the left, the fourth elastic member 312 starts to reset, and the stop collar 310 resets under the action of the fourth elastic member 312, that is, the stop collar 310 moves in a direction away from the packing auger 303. Each reciprocation of the piston plate 203 drives the stop collar 310 to move in a direction approaching the auger 303, so that the auger 303 can continuously rotate to continuously convey the slag to the slag discharge port 302. Simultaneously, the auger 303 is rotated through the piston plate 203, so that an additional driving device can be avoided, and energy sources are saved.
The following describes a specific working procedure of the device for extracting the effective components of the traditional Chinese medicinal materials according to the embodiment:
feeding:
the Chinese medicinal materials are fed from the feed port 103, and the extract and other liquid are discharged into the housing 100 through the liquid feed port 104.
Extraction reaction:
after the heating pipe 112 is started, the heating pipe 112 heats the liquid in the shell 100 to a preset temperature (the preset temperature refers to the temperature required by the reaction between the Chinese medicinal materials and the extract), a stirring motor (not shown) is started to drive a stirring paddle (not shown) to rotate so as to fully mix the Chinese medicinal materials with the extract, and after the preset stirring time, the stirring motor stops working, so that the effective components of the Chinese medicinal materials are mixed with the residues of the Chinese medicinal materials.
And (3) filtering:
the cylinder 204 is activated so that the piston plate 203 in the housing cylinder 201 reciprocates in the axial direction in the housing cylinder 201. In the initial state, the volume of the accommodating chamber 220 of the accommodating tube 201 is minimum, the volume of the collecting chamber 230 is maximum, and the collecting chamber 230 is filled with liquid. The piston plate 203 moves to the right, referring specifically to fig. 6, the volume of the accommodating chamber 220 increases, and since the check valve 211 is provided in the drain pipe 210, only the liquid can be discharged, and the air cannot enter the accommodating chamber 220 from the drain pipe 210, so that the accommodating chamber 220 generates negative pressure, and the liquid enters the accommodating chamber 220 from the liquid inlet pipe 221 through the first filter plate 222 and the grating plate 223.
In the process of entering the accommodating cavity 220, if the slag on the first filter plate 222 is excessively accumulated, the acting force of the flowing liquid is increased when the first filter plate 222 filters the liquid, so that the first filter plate 222 overcomes the acting force of the first elastic piece 226 to move, the first filter plate 222 moves in the liquid inlet pipeline 221 along the flowing direction of the liquid, and when the volume of the accommodating cavity 220 reaches the maximum, the first filter plate 222 reaches the preset position, and the first filter plate 222 is limited by the limiting block 241. At this time, the flow restricting block 224 on the first filter plate 222 moves in synchronization with the first filter plate 222, and the flow restricting block 224 protrudes out of the through holes of the grating plates 223, so that the gap between the flow restricting block 224 and the through holes of the grating plates 223 increases; if less slag is accumulated on the first filter plate 222, the first filter plate 222 cannot overcome the acting force of the first elastic member 226, so that the first filter plate 222 is hardly moved, the liquid flows through the filter holes of the first filter plate 222, and the flow limiting block 224 moves against the acting force of the third elastic member 228 under the action of the liquid flow through the gaps between the flow limiting block 224 and the through holes, so that the gaps between the flow limiting block 224 and the through holes of the grating plate 223 are increased, and the liquid can enter the accommodating cavity 220.
When the piston plate 203 moves to the far right, that is, when the volume of the accommodating chamber 220 is maximum, the piston plate 203 moves to the left so that the volume of the accommodating chamber 220 is reduced, most of the liquid in the accommodating chamber 220 is discharged from the liquid discharge pipe 210 to the outside of the housing 100, and another part of the liquid passes through the gap between the flow limiting block 224 and the through hole of the grating plate 223, and the size of the gap is adjusted according to the blocking degree of the first filter plate 222 when the first filter plate 222 filters the liquid, and the part of the liquid backflushes the first filter plate 222 through the gap. The greater the blocking degree of the first filter plate 222, the greater the gap between the flow restriction block 224 and the through hole of the grating plate 223, the more liquid flows through, and the greater the impact force on the first filter plate 222; the smaller the degree of clogging of the first filter plate 222, the smaller the gap between the flow restricting block 224 and the through hole of the grating plate 223, the less liquid flows through, and the smaller the impact force to the first filter plate 222.
Collecting slag:
at the same time as the volume of the receiving chamber 220 becomes smaller, the volume of the collecting chamber 230 increases, water is absorbed in the collecting pipe 231, and since the opening of the collecting pipe 231 faces the liquid inlet pipe 221 and the second filter plate 232 on the opening of the collecting pipe 231 is opened, the slag washed down on the first filter plate 222 is collected by the collecting pipe 231, and the slag in the collecting pipe 231 is accumulated in the collecting chamber 230 at a position close to the filter cartridge 301. When the volume of the collection chamber 230 reaches the maximum, the liquid in the containing chamber 220 is completely discharged, and the piston plate 203 pushes the push rod 242 of the limiting block 241, so that the limiting block 241 slides in the limiting groove 243 against the acting force of the second elastic member 227, so that the limiting block 241 does not limit the first filter plate 222 any more, and the first filter plate 222 is reset under the action of the first elastic member 226.
Discharging slag:
when the piston plate 203 moves to the right, the volume of the collecting cavity 230 is reduced, the second filter plate 232 at the opening of the collecting pipe 231 closes the opening, a small part of the slag in the collecting pipe 231 moves to the second filter plate 232, but is blocked by the second filter plate 232 and does not enter the shell 100 again, most of the slag is at one end of the filter cylinder 301, when the piston plate 203 moves to the right to be in contact with the limit ring 310, the piston plate 203 continues to move to the right to enable the limit ring 310 to move towards the direction close to the auger 303 against the acting force of the fourth elastic piece 312, the auger 303 rotates, the slag is conveyed to the slag discharge port 302 by the auger 303, during conveying, the spacing between the blades 304 of the auger 303 is gradually reduced to enable the slag to be extruded, the extruded liquid is discharged through the sieve holes on the filter cylinder 301, and the slag falls into the discharge cavity 111 through the slag discharge port 302 and then is discharged out of the shell 100.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
