Description

Technical Field

[0001] The utility model relates to the field of garbage compression, in particular to an intelligent automatic hydraulic control system for a multifunctional garbage compressor. Background Art

[0002] The hydraulic system of the multifunctional garbage compressor is an auxiliary equipment of the multifunctional garbage compressor, including a hydraulic power station, a hydraulic control valve group, an actuator (hydraulic cylinder), etc., which provides hydraulic power and hydraulic control for the multifunctional garbage compressor, and realizes the multifunctional garbage compressor's pre-compression, pressing, water filtration and anti-inclusion and other garbage processing functions. In the past, the hydraulic system of the compressor with pre-compression and pressing mode adopted a primary pressure circuit and no fast retreat circuit and fast forward regeneration circuit to control the operation of the compression cylinder. The main technical solution of the hydraulic control system is: the pusher feeds the material into the compressor to the set value, the compressor push head (compression cylinder) starts to push the material into the garbage bin, and retreats after pushing the material, and so on. When the garbage bin is loaded to the set value and the push head pressure rises to the set value, the compressor push head (compression cylinder) starts to retreat and stop pushing the material into the garbage bin, and then closes the box door to complete the packing process.

[0003] The above problems exist. Since the compression cylinder of the compressor push head only uses a primary pressure circuit and does not have a fast reverse circuit and a fast forward regeneration circuit, the hydraulic control system generates a lot of heat, resulting in high energy consumption of the system, and also reduces working efficiency; the high heat generated by the hydraulic control system also makes the equipment prone to failure, the maintenance workload is large, and the maintenance cost is also increased; since the hydraulic control system has only a primary pressure circuit, the impact of the cylinder when starting to retreat is very large, which will cause vibration of the equipment and the hydraulic system; since the hydraulic control system has only a primary pressure circuit, there is no way to control the synchronous retreat and descent of the compressor push head and the garbage bin gate, which will cause garbage to be mixed after the garbage bin gate is closed. Utility Model Content

[0004] (1) Technical problems solved

[0005] The purpose of the present invention is to provide a multifunctional garbage compactor intelligent automatic hydraulic control system to solve the problem in the above background technology that it is inconvenient to adjust the safety protection range according to different usage scenarios and usage requirements.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a multifunctional garbage compactor intelligent automatic hydraulic control system, comprising a power element part, a control element part, an executive element part and an auxiliary element part, wherein the power element part comprises a motor, a double vane pump group, etc., the control element part comprises a directional valve, a pressure valve, a throttle valve, a one-way valve, an electromagnetic ball valve, a pressure relay, etc., the executive element part comprises a compression cylinder, etc., and the auxiliary element part comprises an oil tank, an oil filter, a liquid level gauge, an air filter, etc.

[0008] Preferably, a secondary pressure control loop is used to achieve synchronous retreat and descent of the compressor push head and the garbage bin gate, thereby avoiding garbage inclusion after the garbage bin gate is closed.

[0009] Preferably, the addition of the fast retreat circuit enables the compression cylinder to retreat quickly and smoothly, thereby avoiding large impact and abnormal noise and vibration of the hydraulic system when the compression cylinder retreats.

[0010] Preferably, the hydraulic system's dual-pump synchronous control principle can use low-pressure, high-flow dual pumps to work during the compressor's pushing process, and use high-pressure, low-flow single pumps to work during the compressor's pressing process, thereby reducing energy consumption and reducing system heat.

[0011] Preferably, when the compressor push head retreats, dual pumps with large flow are used to improve work efficiency, and a fast retreat circuit is added to the system.

[0012] Preferably, the hydraulic control system uses an electromagnetic overflow valve to control the pressure of the system. When the system is working, the electromagnetic overflow valve is energized to provide system pressure, thereby driving the oil cylinder to operate.

[0013] Preferably, when the system is in standby mode, the electromagnetic overflow valve is not energized and is in an unloading state, and the hydraulic oil of the duplex pump returns directly to the oil tank at a very low pressure.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This utility model adopts a two-level pressure control circuit, which reduces the heat generation of the entire hydraulic control system, thereby reducing the energy consumption of the system. It can also realize the synchronous retreat and descent of the compressor push head and the garbage bin gate, avoiding garbage inclusion after the garbage bin gate is closed. The addition of a fast retreat circuit allows the compression cylinder to retreat quickly and smoothly when retreating, avoiding large impact, abnormal noise and vibration of the hydraulic system when the compression cylinder retreats, and also improves work efficiency. The addition of a fast forward regeneration circuit allows the compression cylinder to advance quickly and smoothly when forward, thereby improving work efficiency.

[0016] 2. This utility model utilizes a rational and scientific configuration of all components throughout the hydraulic control system, fully utilizing the functionality of each component to provide safe and reliable power for the multi-functional garbage compactor. By adding a rapid reverse circuit and a rapid forward regeneration circuit, vibrations in the equipment and hydraulic system caused by the impact of the cylinder during reverse startup are effectively eliminated. This effectively improves the efficiency of the multi-functional garbage compactor, reduces energy consumption, minimizes equipment failures, reduces maintenance workload, and reduces manufacturing costs.

[0017] 3. The dual-pump synchronous control principle of the hydraulic system of this utility model can use low-pressure, high-flow dual pumps to work during the compressor pushing process, thereby improving work efficiency; use high-pressure, low-flow single pumps to work during the compressor pressing process, thereby reducing energy consumption and reducing system heat; when the compressor push head retreats, dual pumps with high flow are used to improve work efficiency, and a fast retreat circuit is added to the system, which greatly reduces the pressure loss of the system, thereby reducing the system's heat generation and energy consumption, achieving the purpose of energy saving.

[0018] 4. The hydraulic control system of this utility model adopts electromagnetic overflow valve to control the pressure of the system. When the system is working, the electromagnetic overflow valve is energized to give the system pressure, thereby driving the oil cylinder to move; when the system is in standby state, the electromagnetic overflow valve is not energized and is in unloading state, and the hydraulic oil of the double pump returns directly to the oil tank at a very low pressure, thereby reducing the heat generation, pressure loss and energy consumption of the system, thereby achieving the purpose of energy saving.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe 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 the embodiments. 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.

[0021] See also Figure 1This utility model provides a technical solution for an intelligent automated hydraulic control system for a multifunctional garbage compactor. The intelligent automated hydraulic control system comprises a power element, a control element, an actuator element, and an auxiliary element element. The power element includes a motor, a double vane pump assembly, etc. The control element includes a directional valve, a pressure valve, a throttle valve, a check valve, a solenoid ball valve, a pressure relay, etc. The actuator element includes a compression cylinder, etc. The auxiliary elements include an oil tank, an oil filter, a liquid level gauge, an air filter, etc. It should be noted that this system utilizes double pump control technology, synchronous control technology, a unique oil circuit design, and unique electro-hydraulic integration and intelligent energy-saving control technology. The system's design principle is to automatically adjust the system's operating pressure and flow rate based on the size of the pressing force, minimizing energy consumption and improving system efficiency. During operation, the equipment can automatically achieve low speed under heavy loads and high speed under light loads, effectively solving the problem of temperature rise in the hydraulic system and ensuring continuous operation in high-temperature environments, making the hydraulic control system more energy-efficient and more efficient.

[0022] Furthermore, a secondary pressure control loop is adopted to achieve the synchronous retreat and descent of the compressor push head and the garbage bin gate, avoiding garbage being mixed in after the garbage bin gate is closed.

[0023] Furthermore, the addition of a fast retreat circuit allows the compression cylinder to retreat quickly and smoothly, avoiding large impact and abnormal noise when the compression cylinder retreats and vibration of the hydraulic system.

[0024] Furthermore, the hydraulic system's dual-pump synchronous control principle allows the use of low-pressure, high-flow dual pumps during the compressor's pushing process, and the use of high-pressure, low-flow single pumps during the compressor's pressing process, thereby reducing energy consumption and system heat generation.

[0025] Furthermore, when the compressor push head retreats, dual pumps are used to operate at a high flow rate to improve work efficiency, and a fast retreat circuit is added to the system.

[0026] Furthermore, the hydraulic control system uses an electromagnetic overflow valve to control the pressure of the system. When the system is working, the electromagnetic overflow valve is energized to provide system pressure, thereby driving the oil cylinder to operate.

[0027] Furthermore, when the system is in standby mode, the electromagnetic relief valve is not energized and is in an unloading state, and the hydraulic oil of the duplex pump returns directly to the oil tank at a very low pressure.

[0028] Working principle: By adding a fast reverse circuit and a fast forward regeneration circuit, the vibration of the equipment and hydraulic system caused by the impact of the cylinder when starting to retreat is effectively eliminated. During the compressor pressing process, a high-pressure, small-flow single pump is used to reduce energy consumption. When the compressor pushes the head backward, a double pump with a large flow is used to improve work efficiency. A fast reverse circuit is added to the system, which greatly reduces the pressure loss of the system, thereby reducing the heat generation of the system. When the system is working, the electromagnetic overflow valve is energized to the system pressure, thereby driving the cylinder to move; when the system is in standby state, the electromagnetic overflow valve is not energized and is in an unloading state, and the hydraulic oil of the double pump returns directly to the oil tank at a very low pressure, thereby reducing the heat generation, pressure loss and energy consumption of the system.

[0029] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Simple modifications or equivalent replacements of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
