The utility model discloses in adopt the plunger pump to carry mud, the plunger pump is an important device of hydraulic system. The plunger reciprocates in the cylinder body to change the volume of the sealed working cavity so as to realize the suction and pressure actions. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency, convenient flow regulation and the like, and is widely applied to occasions with high pressure, large flow and flow needing regulation, such as hydraulic machines, engineering machinery and ships. However, the plunger pump has the following disadvantages when applied to an industrial process for sludge transportation: firstly, the plunger pump is high in cost, the overall cost of a sludge conveying channel using the plunger pump is too high, secondly, a plunger structure in the plunger pump is easily polluted by sludge and easily damaged, secondly, the plunger structure of the plunger pump is easily abraded in the process of bearing high pressure for a long time, and the damage rate of equipment is high, so that the plunger pump is simply applied to the sludge conveying process, and the plunger pump is in a high-pressure sludge conveying state for a long time, the service life of the plunger pump is shortened, and the reliability of the whole device is reduced.
In addition to plunger pumps, diaphragm pumps are also commonly used in industrial processes for sludge transport, and the operating principle of diaphragm pumps is similar to that of plunger pumps, and the liquid to be infused is separated from the plunger and the pump cylinder by means of a thin film, so that the plunger and the pump cylinder are protected. The left side of the diaphragm, which is in contact with the liquid, is made of corrosion-resistant materials or coated with a layer of corrosion-resistant substances; the right side of the diaphragm is filled with water or oil. For example, patent application No. 201220085255.9 discloses a sludge treatment apparatus including a reaction tank, a pneumatic diaphragm filter press, an air compressor unit, a water storage tank, a pneumatic diaphragm pump, a high pressure water pump; the bottom of the reaction tank is communicated with the inlet of the pneumatic diaphragm pump, and the outlet of the pneumatic diaphragm pump is communicated with the sludge inlet of the pneumatic diaphragm filter press and the sludge inlet of the reaction tank; the sludge source pipeline is communicated with the inlet of the pneumatic diaphragm pump through a fifth valve; the air compressor unit is communicated with an air inlet of the movable diaphragm pump through a sixth valve by using a first compressed air pipe, and the first compressed air pipe is communicated with a power gas inlet of the pneumatic diaphragm filter press through a seventh valve; the water outlet of the water storage tank is communicated with the inlet of a high-pressure water pump, and the outlet of the high-pressure water pump is communicated with the cleaning water inlet of the pneumatic diaphragm filter press through a high-pressure water pipe for the eighth valve. The utility model discloses area is little, and is lower to the treatment cost of mud. The utility model discloses a well simple power device who uses the diaphragm pump as mud transport, in the practical application process, the diaphragm pump exports high pressure for a long time, easily leads to the diaphragm elasticity to become invalid, shortens the life-span of diaphragm pump.
From the above two patent application documents, it is clear that in practical application, in order to smoothly convey sludge from a sludge pool to a filter press for filter pressing, a large pressure needs to be applied to the sludge, however, no matter a plunger pump or a diaphragm pump, a pressure pump is simply applied to pressurize the sludge, and in a long-term high-pressure working state, the pressure pump works slowly, which inevitably results in serious loss of the pressure pump, shortens the service life of the whole device, and further fails to achieve a good sludge conveying effect.
