Power device used for garbage compression

Abstract

The invention provides a power device used for garbage compression. The power device comprises a fuel tank assembly, a hydraulic valve bank assembly and a power assembly. The fuel tank assembly comprises a fuel tank and an oil pump. The hydraulic valve bank assembly comprises a one-way valve, a first two-position four-way electromagnetic valve, a second two-position four-way electromagnetic valveand a hydraulic control one-way valve. An inlet of the one-way valve communicates with an oil outlet of the oil pump. An outlet of the one-way valve communicates with a P oil port of the first two-position four-way electromagnetic valve and a P oil port of the second two-position four-way electromagnetic valve through an oil inlet pipe. A T oil port of the first two-position four-way electromagnetic valve and a T oil port of the second two-position four-way electromagnetic valve communicate with the fuel tank through a main oil return pipe. A branch oil return pipe is arranged on the main oilreturn pipe. The main oil return pipe and the oil inlet pipe communicate with a two-position two-way electromagnetic valve. An inlet of the hydraulic control one-way valve communicates with the main oil return pipe. The power assembly comprises a push oil cylinder communicating with the first two-position four-way electromagnetic valve. By means of the power device provided by the invention, the operating noise can be lowered, the service life can be prolonged, and the continuous operating stability is guaranteed.

Description

technical field [0001] The invention relates to the field of brazing of water-cooled plates, in particular to a power device for garbage compression. Background technique [0002] At present, the working environment of the garbage compression system is harsh, and the working time is long. Generally, it takes 8-10 hours continuously, and the work intensity is high. The traditional garbage compression power unit has the following problems due to unreasonable design: (1) Start with load and do not have cooling capacity , causing the oil temperature of the equipment to be as high as 85°C, and the failure rate is high; (2) The continuous operation has poor stability and poor performance, resulting in the accumulation of garbage on site, which cannot be processed and transferred in time, affecting environmental sanitation and the normal work and life of residents; (3) The power unit The self-weight is relatively heavy, up to about 200kg. At least two people are required to coopera...

Problems solved by technology

[0002] At present, the working environment of the garbage compression system is harsh, and the working time is long. Generally, it takes 8-10 hours continuously, and the work intensity is high. The traditional garbage compression power unit has the following problems due to unreasonable design: (1) Start with load and do not have cooling capacity , causing the oil temperature of the equipment to be as high as 85°C, and the failure rate is high; (2) The continuous operation has poor stability and poor performance, resulting in the accumulation of garbage on site, which cannot be processed and transferred in time, affecting environmental sanitation and the normal work and life of residents; (3) The power unit The self-weight is relatively heavy, up to about 200kg. At least two people are required to cooperate to pull it out during maintenance and installation. The efficiency is low. At the same time, too high self-weight will directly affect the loading capacity of each garbage, increasing the fuel consumption of the car and (4) When the compression box is driven by the power device to compress the garbage, the running noise is high and the reversing impact is large, which has a very bad impact on the lives of the surrounding residents.
