[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-3 , the embodiments of the present utility model include:

[0024] A solid-liquid separation device for kitchen waste, the structure of which includes: a crushing chamber 13, a filter press chamber 14, a mounting boss 1, a crushing cutter head 2, a separating valve 3, a water filter valve 4, a solid-liquid separation valve 5, a pressing plunger head 6, a pressing push rod 7, a filter residue valve 8, a plunger far point limiter 9, a garbage sleeve 10, a high-pressure nozzle 11, and a plunger near point limiter 12.

[0025] The mounting boss is arranged at the feed port on the top of the crushing bin so that the solid-liquid separation device can be installed under a kitchen countertop, sink or basin used in daily household. A crushing cutter head is arranged in the crushing bin, and the rotary drive device drives the crushing cutter head to rotate in the crushing bin to crush harder materials, especially kitchen residues such as bones. The diameter of the crushing cutter head is smaller than the diameter of the crushing bin so that a certain gap is retained between the outermost end of the crushing cutter head and the inner wall of the crushing bin. This not only facilitates the control of the crushing accuracy, but also prevents various blockage problems caused by the material being crushed too finely.

[0026] Further preferably, a sensor for detecting the amount of waste is provided in the crushing bin. When the waste in the crushing bin accumulates to a level that is sensed by the sensor, the crushed waste can be prepared to be sent to the filter press bin.

[0027] Further preferably, the mounting boss can be installed and fixed by bonding, screws, etc.

[0028] Further preferably, the mounting boss is disposed around the outer peripheral wall of the feed port.

[0029] More preferably, the rotation drive device may be a drive motor or the like.

[0030] Further preferably, one or more groups of crushing cutter heads are provided in the crushing chamber, and gaps are provided between adjacent crushing cutter heads.

[0031] The inclined filter press chamber is connected to the bottom of the crushing chamber. A separating valve is radially located at the connection between the crushing chamber and the filter press chamber to open or close the connection between the two chambers. The separating valve is normally closed. When the waste material to be processed enters the crushing chamber, the separating valve opens. After a certain period of crushing, the valve blades automatically rotate open to allow the waste material to fall out.

[0032] Further preferably, the crushing chamber and the filter press chamber are an integrated structure.

[0033] More preferably, the separation valve may be an existing electric valve, such as a butterfly valve, a one-way check valve, etc., in which a valve body may have eight opening and closing blades.

[0034] A solid-liquid separation valve is radially installed in the filter press chamber near the separation valve. The blades of the solid-liquid separation valve are provided with filter holes 51 to facilitate the filtration of the filtrate. The solid-liquid separation valve is normally closed and synchronizes with the opening and closing state of the separation valve. That is, when the separation valve is opened, the solid-liquid separation valve also opens synchronously. When the crushed waste enters the filter press chamber, the solid-liquid separation valve and the separation valve close synchronously.

[0035] A drain outlet 15 is provided on the side wall of the filter press chamber between the separation valve and the solid-liquid separation valve. The outer side of the drain is connected to the drainage pipe of the kitchen. The water filter valve is provided in the drain outlet. The water filter valve is in an open state under normal circumstances. When the crushing blade is started, it is immediately closed.

[0036] Further preferably, the solid-liquid separation valve and the partition valve have the same structure.

[0037] Further preferably, the water filter valve is arranged at a low position of the filter press bin close to the solid-liquid separation valve to facilitate the outflow of the filtrate.

[0038] The plunger head is movably positioned within the filter press chamber. Its outer circumference is fitted (wrapped) with a flexible silicone ring that adheres tightly to the chamber's inner wall. This ring ensures the plunger head's orderly movement while maintaining a good seal between it and the chamber. A push rod is connected to the rear end of the plunger head. Driven forward or backward by a plunger head drive device (such as an electric motor), the plunger head moves back and forth along the chamber's inner wall, moving closer to or further away from the solid-liquid separation valve, thereby physically compressing the material within the chamber.

[0039] The plunger's distal limiter is located on the rear inner wall of the filter press chamber to limit the plunger's outermost position. The plunger's proximal limiter is located on the inner wall of the filter press chamber below the solid-liquid separation valve to limit the plunger's innermost position. A high-pressure nozzle is located within the filter press chamber between the solid-liquid separation valve and the plunger's proximal limiter to deliver high-pressure water to flush components such as the filter press chamber, solid-liquid separation valve, separation valve, and plunger head.

[0040] The discharge port is located on the lowest sidewall of the filter press chamber between the plunger's near-point limiter and the plunger's far-point limiter. A filter residue valve is installed within the discharge port to discharge the filter residue. A garbage collection port is connected to the outside of the discharge port to collect solid waste. The filter residue valve is normally closed. When the filtration is complete and the plunger head is pushed to the far-point limiter, the filter residue valve automatically opens, allowing the residue to pass through the discharge port and into the garbage bag at the garbage collection port.

[0041] Further preferably, the limiting portion may be a limiting convex ring or a limiting boss.

[0042] Further preferably, one or more high-pressure nozzles are provided in the filter press bin.

[0043] Further preferably, the garbage sleeve and the filter press bin are an integrated structure.

[0044] Working steps of solid-liquid separation device:

[0045] Step 1: Start the device, the separation valve, solid-liquid separation valve, and filter residue valve are closed synchronously, and the water filter valve is in the open state;

[0046] Step 2: The material to be processed is pushed into the crushing chamber in batches from the feed port, and the crushing cutter head rotates intermittently to ensure the material crushing accuracy and prevent material splashing;

[0047] Step 3: When the material in the crushing chamber submerges the crushing cutter head, the separation valve and the solid-liquid separation valve are opened simultaneously, and the filter valve is closed, so that the crushed material enters the filter press chamber;

[0048] Step 4: When a certain amount of material is stored in the filter press bin or the separation valve and the solid-liquid separation valve are opened for a certain period of time according to the preset time, the separation valve and the solid-liquid separation valve are closed synchronously, and the water filter valve is opened;

[0049] Step 5: Control the driving device of the plunger head and the push rod to start, so as to drive the plunger head close to the solid-liquid separation valve for filter pressing. The pressure is fixed and maintained in a compacted state for 5 seconds to maximize the filter pressing effect. As the space between the plunger head and the solid-liquid separation valve is reduced, the aqueous waste filtered out by the solid-liquid separation valve and the plunger head overflows from the filter press hole on the solid-liquid separation valve and is discharged to the outside through the drain port, while the solid waste remains in the filter press chamber.

[0050] Step 6: When the plunger head retreats backward to the position of the plunger far point limiter, the filter valve is opened synchronously, so that the solid material can enter the garbage bag through the discharge port;

[0051] Step 7: After the solid waste is discharged, the plunger head moves forward again to the plunger near-point limit position, and the filter valve is closed synchronously;

[0052] Step 8: Start the high-pressure nozzle to clean the filter press chamber, especially the filter press hole on the solid-liquid separation valve, and discharge the flushing water into the municipal pipe network through the drain port;

[0053] Step 9: After cleaning, the plunger head is withdrawn to the plunger far point limit position, the separation valve, solid-liquid separation valve, and water filter valve remain open, and the filter residue valve remains closed.

[0054] The beneficial effects of the solid-liquid separation device for kitchen waste of the utility model are:

[0055] 1. It can indiscriminately collect household organic matter and a small amount of inorganic matter generated in the kitchen, and crush and filter the kitchen waste to achieve solid-liquid separation, allowing liquid substances to enter the municipal pipe network, and solid substances to be discharged and collected through the discharge port, making it easy to package and transport them, thereby improving the efficiency and quality of waste treatment and increasing the overall kitchen waste collection and storage capacity of the city;

[0056] 2. It can realize the separation of dry and wet kitchen waste, further improving the feasibility of household waste resource utilization;

[0057] 3. It has the characteristics of one-button start and full automation, which effectively improves work efficiency and convenience of use.
