Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1

[0027] like Figure 1 As shown, this embodiment provides a hydraulic device for solid-liquid separation of municipal solid waste, including a hydraulic mechanism 1, a compression cylinder (not shown), and a control system (not shown).

[0028] like Figure 1 As shown, the hydraulic mechanism 1 is equipped with a compression cylinder (not shown in the figure), and the control system (not shown in the figure) can control the hydraulic mechanism 1 to perform solid-liquid separation on the domestic waste in the compression cylinder.

[0029] like Figure 1As shown, the hydraulic mechanism 1 comprises an oil tank 11, a motor 12, a pressure sensor 13, a pressure gauge 14, a temperature sensor 15, a finned radiator 16, a cooling fan 17, and an electromagnetic valve 18. The oil tank 11 is made of castings, with a thickness of 3 mm, good structural strength, and baked paint treatment on the inner and outer surfaces. A fixing seat 111 is fixed to the bottom of the oil tank 11, allowing the mechanism to be fixed on the compression cylinder body through bolt connection. A liquid level gauge 112 is fixed to one side wall of the oil tank 11, allowing real-time observation of the oil quantity. A blowdown port is provided at the bottom of one side wall of the oil tank 11, and a blowdown valve 113 is fixed to the blowdown port, allowing periodic emptying of waste oil in the oil tank 11. In the example, the liquid level gauge 112 and the blowdown valve 113 are arranged on the same side wall. An oil filling port 114 is provided on the top wall of the oil tank 11, and an oil outlet 115 is also provided on the top wall of the oil tank 11. The motor 12 is fixed to the top wall of the oil tank 11, capable of converting electrical energy into liquid pressure. The pressure sensor 13 and the temperature sensor 15 are fixed to the top wall of the oil tank 11 beside the motor 12. The pressure gauge 14 is fixed to the top wall of the oil tank 11 beside the pressure sensor 13, electrically connected with the pressure sensor 13, and capable of observing the oil pressure in real time. The temperature sensor 15 is electrically connected with the cooling fan 17. The finned radiator 16 is fixed to one side wall of the oil tank 11, and the cooling fan 17 is fixed to the side wall of the finned radiator 16. The cooling fan 17 controls the on-off state according to the feedback information of the temperature sensor 15, ensuring that the oil temperature is maintained within a normal range during operation of the mechanism.

[0030] As shown in Figure 1 The top wall of the finned radiator 16 is connected with the electromagnetic valve 18 through the first pipeline 161. The electromagnetic valve 18 is provided with multiple electromagnetic valves 18, each of which is electrically connected with the control system. The multiple electromagnetic valves 18 are combined to form an action control execution unit. Each electromagnetic valve 18 is connected with different oil paths, and the on-off state of the electromagnetic valve 18 is controlled according to the instruction of the control system, so as to realize the action of the compression cylinder body for solid-liquid separation of household garbage, complete the compression and separation of garbage, and the like. The top wall of the finned radiator 16 is connected with the oil outlet 115 through the second pipeline 162.

[0031] In use, the motor 12 pumps the oil along the oil outlet 115 and the second pipeline 162 into the finned radiator 16. The cooled oil enters the oil tank 11 and other terminals along the first pipeline 161 and the electromagnetic valve 18. The hydraulic principle is adopted to convert the pressure of the liquid into mechanical energy to separate the solid and liquid of the household garbage. The hydraulic mechanism 1 is provided with temperature, pressure, and other sensors, capable of monitoring and feeding back the operation data in real time to ensure the operation of the device and solve the risk of jamming of the conventional screw type treatment device on the market, which may cause the motor in the transmission module to burn out, the gear to be damaged, and the belt to be broken.

[0032] The hydraulic mechanism 1 is used in combination with the compression cylinder body for solid-liquid separation of household garbage, and the control system is automatically and accurately controlled to realize the compression ratio and dehydration rate of garbage, specifically as follows.

[0033] High pressure extrusion dewatering, extrusion pressure is provided by hydraulic mechanism, the whole process is carried out in the cylinder; extrusion is through the action of high pressure on the living and residual garbage, using the characteristics of low compression strength and good fluidity of residual components, so that it is crushed, and the leachate in the mixed garbage is slurried together, and the wet components are separated and flow out of the screen hole in the extrusion process; and the high calorific value components such as plastic, bamboo and wood, and fabric which are not slurried are retained in the reduced extrusion cavity, and are further dewatered by high pressure to form dry components, which are discharged when the extrusion pressure is released, so that dry and wet separation of household garbage is realized; at the same time, the hard materials such as metal and bone mixed in the garbage are reduced in volume by high pressure extrusion;

[0034] This separation process can be divided into three stages according to the state of the easily degradable components: tissue destruction, extrusion separation and high pressure extrusion; in the first stage, the pressure starts from 0 and increases, the voids between the components of the garbage gradually decrease to compaction, the physical structure of each component begins to deform, and the kitchen waste components are destroyed; in the second stage, when each component is destroyed and compacted, the material close to the screen hole and having good ductility begins to flow out, and the volume of the garbage continues to decrease, but the plastic bags with strong toughness will wrap the broken components and hinder their flow, until the pressure reaches a certain degree, the plastic bags are broken, and the easily degradable components can flow out, therefore, in order to improve the ductility of the garbage, the living garbage needs to be pretreated by bag breaking and coarse crushing before high pressure extrusion separation; in the third stage, the broken material is extruded by high pressure, and the extrusion degree is determined by the extrusion pressure, and is also related to the volume of the screen cylinder, the shape of the screen hole and the components of the garbage; generally speaking, the easily biodegradable organic components such as potatoes, apples and carrots can be completely extruded under a certain pressure, and the water content of the waste with more fiber such as fruit peels, vegetable stems and fallen leaves will also be significantly reduced, such as the water content of the residual material after pretreatment of vegetable stems is only 40% to 45%.

[0035] The above examples are only used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
