Embodiment Construction
[0035] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0036] see figure 1 , preferred embodiment 1 of the present invention provides a mixed valve-controlled pressure air fetching and unloading system, comprising an air pressure output device 1, a two-position three-way valve 6, a shut-off valve 5, a first pipeline tee 4, a second Two pipes and tees 11, carrying tank 12 and connecting pipes 7, 8, 13, 15, 18, 19, air intake pipe 3, air supply pipe 16, and input pipe 9 and outlet 10 for defecation.
[0037] The first end and the second end of the two-position three-way valve 6, the third end and the second end of the first pipeline three-way valve 4 and the connecting pipeline form the gas input with the pressure air output device 1 inside the carrying tank 12. The connecting channel at the end 2, where...

The invention provides a mixing valve control pressure air feces picking and discharging system. A traditional vacuum feces picking and discharging system device represented by a vacuum fecal suction truck is replaced by a pressure air feces picking and discharging system device. The system comprises a carrying tank, an air pressure output device, a two-position three-way valve, a cut-off valve, pipeline tee joints and connecting pipelines. The system has the advantages that compared with the vacuum feces picking and discharging system, composition of the feces picking and discharging system is remarkably simplified, a sealed feces storage device is supported to implement pressure air feces picking and forced feces discharging, odor leakage in the feces picking process is avoided, environments are protected, the system is simpler and more convenient to maintain and operate, the feces picking depth can be greatly increased, requirements for materials and machining of the carrying tank are lowered, reduction of the manufacturing cost of a tank wagon is promoted, and the existing pressure air feces picking and discharging technology is enriched.
Description
technical field [0001] The invention relates to the field of excrement fetching and transporting devices, in particular to a mixing valve-controlled pressure air feces fetching and unloading system used on the feces fetching and transporting device. Background technique [0002] For the fetching and transporting of stored feces, the currently widely used device for fetching and transporting feces is a vacuum suction truck. The specific application of vacuum fecal suction truck has the following shortcomings: [0003] 1. The core equipment of the feces collection system is a vacuum pump. The system generally includes: oil-gas separator, water-gas separator, coarse filter, anti-overflow valve, vacuum pressure gauge, etc. The system structure is complex; [0004] 2. It is difficult to take a depth of more than seven meters for the storage of feces, which is not conducive to the implementation of the closed feces storage model and the storage body restricted by the topography, ...
