Embodiment 1
[0026] This embodiment further introduces the application in conjunction with the accompanying drawings:
[0027] (1) Shredding of domestic waste: Before the dewatering treatment of municipal domestic waste, it is necessary to crush the waste to fix the volume of the waste within a certain range and prevent some domestic waste from being too large to block the pressure head of the extrusion device. The crushing method is shear crushing, which cuts domestic waste into a length of about 10-20cm and pre-compresses it into a height of about 5cm.
[0028] (2) The working process of the domestic garbage dewatering device: the hydraulic control system controls the work of the transmission device, and transports the sheared and pre-compressed garbage to the bottom of the first-stage pressure head. The hydraulic system drives the rotating shaft to rotate, and at the same time moves downward to approach the required Extruded garbage. The ring-shaped slope pressure head is a pair of mal...

Abstract
The invention discloses a novel household garbage extrusion water removal method and device. The device comprises a hydraulic control system, a conveying device and an extruding device. The conveyingdevice comprises a conveying belt, a pressure tank seat and a pressure tank. The pressure tank is mounted on the pressure tank seat. The pressure tank seat is located above the conveying belt. The extruding device comprises a pressure lever, pressure heads and rotating shafts. The top of each rotating shaft is connected with the pressure lever. The pressure lever is further connected with the hydraulic control system. Each pressure head is arranged at the bottom of the corresponding rotating shaft. The pressure heads are arranged in the pressure tank. The novel household garbage extrusion water removal device has the advantages of being easy to operate, standardized and complete in production flow, low in manpower and material resource consumption, low in production cost, high in resourcerecovery efficiency, environmentally friendly and the like.
Description
technical field [0001] The invention relates to a method and a device for treating urban domestic garbage, in particular to a novel method and device for squeezing and removing water from domestic garbage. Background technique [0002] The development trend of municipal solid waste treatment technology is green environmental protection, no pollution, high efficiency, low operating cost, and high added value of products. However, the following problems exist in the current process of municipal solid waste treatment: serious environmental pollution, many safety hazards, Energy consumption is too large and product cost is too high. The existence of these problems has led to low efficiency of domestic waste treatment in my country, aggravated environmental pollution, and unsustainable industry development. Therefore, the development of new technologies with high efficiency, energy saving, environmental friendliness, and complete resource utilization has become an important direc...
