The following detailed description of implementations of the invention refers to specific embodiments.
Referring to FIG. 1, a preferred embodiment of the present invention is provided.
The piston extrusion type solid-liquid filtering mechanism is used for filtering out water in kitchen residue smashed with water, and comprises a piston cylinder body 100, and a driving piston mechanism and a driven piston mechanism which are positioned in the piston cylinder body 100 and are used for extruding and dehydrating the kitchen residue; the cylinder 100 has a feed opening formed at an upper end thereof for feeding the kitchen waste, a water filter 140 for filtering water and a discharge opening 130 for discharging the solid waste having the water filtered therein.
In the present embodiment, the piston cylinder 100 is a cylindrical tubular cylinder with two penetrating ends, wherein one end of the piston cylinder 100 is provided with a driving piston mechanism, while the middle of the piston cylinder 100 is provided with a driven piston mechanism, and for tightness, a baffle is provided at the other end of the piston cylinder 100 opposite to the driving piston mechanism, but the baffle may not exist.
The driving piston mechanism comprises a driving piston plate 230 for pressing kitchen residues and a driving device for driving the driving piston plate 230 to move in the piston cylinder 100; the slave piston mechanism is located inside the piston cylinder 100, and includes a slave piston plate 300 for pressing kitchen waste and a pressure-receiving mechanism for receiving pressure transmitted from the master piston plate 230.
The pressure-bearing mechanism has two functions; one is to impart a reaction force to the master piston plate 230 to produce the squeezing action; but rather serves to reset the slave piston plate 300 pushed away from the initial position.
It should be noted that the reference to the master piston plate 230 and the slave piston plate 300 is not meant to be plate members, and the description of the plate is merely for the purpose of distinguishing from the piston mechanism, and may actually be other shapes. Any structure that can perform the squeezing and dewatering of the kitchen waste in the piston cylinder 100 by the movement thereof is within the expression range of the driving piston plate 230 and the driven piston plate 300. The surfaces of the driving piston plate 230 and the driven piston plate 300 for compressing kitchen waste are not limited, and the description of the plate-like shape does not suggest that they are flat surfaces, and they may be curved surfaces or other structures that are fitted to each other.
The piston-pressing solid-liquid filtering mechanism provided by this embodiment utilizes a piston-type structure, kitchen waste is fed into the space between the driving piston plate 230 and the driven piston plate 300 through the feeding hole, then the driving piston plate 230 is pushed to move by the lever 210 type transmission mechanism after receiving driving force, then the kitchen waste is pushed to and pressed and filtered by the driving piston plate 230 and the driven piston plate 300, the filtered water is discharged by the water filtering portion 140, and the solid waste is discharged by the discharging hole 130. The piston type water filtering mechanism enables the kitchen residue to obtain positive extrusion force in water filtering action of the kitchen residue, and extrusion degree of the kitchen residue can be accurately controlled by the motion stroke of the driven piston plate 300, so that water filtering accuracy is improved.
The driving mechanism includes a lever 210 mechanism, and the lever 210 mechanism includes a lever 210 rotatable around a fulcrum and a connecting member 220 having both ends respectively hinged to the end of the lever 210 and a driving piston plate 230. The lever 210 type transmission mechanism has good rigidity and the characteristic of enlarging and reducing the driving force, and is very suitable for the water filtering mechanism.
Since the cross section of the piston cylinder 100 in this embodiment is circular, the driving piston plate 230 and the driven piston plate 300 are both circular plates, so that the driving piston plate 230 and the driven piston plate 300 may rotate when moving in the piston cylinder 100. In order to avoid this, when the master piston plate 230 and the slave piston plate 300 move in the piston cylinder 100, only the axial movement in the piston cylinder 100 is generated, in this embodiment, a guide rod 110 for guiding the master piston plate 230 and the slave piston plate 300 is further transversely provided in the piston cylinder 100, and guide holes 310 for engaging with the guide rod 110 are respectively provided in the master piston plate 230 and the slave piston plate 300.
Thus, the engagement of guide rods 110 with guide holes 310 limits the freedom of rotation of master piston plate 230 and slave piston plate 300. So that the motion of the master piston plate 230 and slave piston plate 300 within the piston cylinder 100 is only an axial translational motion.
In order to enhance the stability of the arrangement of the guide bar 110, in the present embodiment, the guide bar 110 is located on the inner wall of the piston cylinder 100.
In this embodiment, the driven piston plate 300 is formed with a pressing surface for pressing kitchen waste and a pressure receiving surface opposite to the pressing surface, and the pressure receiving mechanism is provided at one side of the pressure receiving surface and includes a pressure receiving spring abutting against the pressure receiving surface.
The bearing surface locations are also provided with positioning rods 320 for positioning the slave piston plate 300, the positioning rods 320 being transversely connected to the bearing surfaces of the slave piston plate 300. The positioning rod 320 is mainly used to fix the position of the driven piston plate 300.
The motion process of the driving piston plate 230 and the driven piston plate 300 is that when the driving piston plate 230 is forced to move, the kitchen waste is driven to move, when the kitchen waste is pushed to contact with the driven piston plate 300, the driven piston plate 300 is forced to be pushed, at this time, the pressing spring is compressed to generate elastic force, the elastic force is compressive force, the kitchen waste is forced by the compressive force to filter out water, and the water is discharged by the water filtering part 140 below. After the moisture filtering is completed, the driven piston plate 300 is pushed above the discharge opening 130, the positioning rod 320 positions the position of the driven piston plate 300, the position of the driven piston plate 300 is limited, and the driven piston plate 300 cannot move, when the driving piston plate 230 returns to the initial position, the pressure of the driving piston plate 230 on the driven piston plate 300 is eliminated, and the solid residue with moisture filtered out slides on the pressing surface of the driven piston plate 300 and falls out of the discharge opening 130. After the solid residue is separated, the positioning rod 320 is not positioned, and the pressure-bearing spring pushes the driven piston plate 300 to return to the initial position.
Two support plates 120 for supporting the piston cylinder 100 are oppositely disposed on the outer wall of the piston cylinder 100; the piston cylinder 100 comprises two guide rods 110 inside, and the two guide rods 110 are respectively and oppositely positioned on the inner walls of two sides of the cylinder 100; the support plates 120 are provided with guide rods 110 on the inner walls opposite to the connection positions on the outer wall of the piston cylinder 100 in a one-to-one correspondence, and the guide rods 110 and the support plates 120 penetrate through the piston cylinder 100 in a one-to-one correspondence, respectively, for connection.
The support plates 120 are used to position the piston cylinders 100, and the guide rods 110 and the support plates 120 are connected through the piston cylinders 100 in a one-to-one correspondence, respectively, in the sense that the connection rigidity of the support plates 120 can be enhanced.
The piston cylinder 100 is obliquely connected to two support plates 120 arranged alternately, so that one end of the piston cylinder 100, in which the active piston mechanism is disposed, faces downward.
The downward arrangement is meant to make the solid residue more likely to fall off the surface of the slave piston plate 300.
In order to enhance the water filtering effect, the lower end edge of the driving piston plate 230 is provided with a tooth-shaped structure for water filtering, and the tooth-shaped structure is further used for cleaning the residue and debris stuck on the water filtering portion 140.
Since solid residue may appear to adhere to the pressing surface of the driven piston plate 300 during actual operation, in order to solve this problem, the surfaces of the driving piston plate 230 and the driven piston plate 300 for pressing are provided with the anti-sticking layer 232 in the present embodiment. The anti-sticking layer 232 may be a simple anti-sticking coating or an anti-sticking material with a certain thickness attached on the surface thereof.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
