Embodiment Construction
[0034] Specific embodiments of the present invention will be described below.
[0035] A bionic spiral high-pressure nozzle for cleaning the filter cloth of a plate and frame machine and a design method thereof according to the present invention comprise the following steps:
[0036] Step 1: Calculate the two-dimensional helix and the three-dimensional helix of the bionic helical high-pressure nozzle, obtain the plane outer contour of the bionic helical high-pressure nozzle from the two-dimensional helix, and obtain the three-dimensional inner contour of the bionic helical high-pressure nozzle from the three-dimensional helix. The formula for calculating the dimensional spiral is:
[0037]
[0038] In formula (1), k is the spiral proportional coefficient, and its value determines the size of the spiral profile; e is a constant; t is the angle of rotation of the spiral, and its value determines the rotation of the spiral in the three-dimensional Cartesian coordinate system ...

The invention relates to a bionic spiral high-pressure nozzle for cleaning filter cloth of a plate-and-frame filter and a design method of the bionic spiral high-pressure nozzle. The bionic spiral high-pressure nozzle is obtained by calculating a two-dimensional spiral line and a bionic three-dimensional spiral line, and a field snail shell structure with good biological characteristics is used, so that an internal flow channel structure is of an excellent spiral structure; when high-pressure water is injected into a cylinder flow channel through a flow inlet, water of the cylinder flow channel is buffered and gathered and then enters a bionic spiral body flow channel again so that the direct-current water in the cylinder flow channel can rapidly become rotating water of the bionic spiralbody internal flow channel, the effect of the direct-current water is continuously increased due to continuous rear surge water of the flow inlet, and then the rotating effect of the rotating water iscontinuously enhanced; especially the design of the shape of the inverted trapezoidal cross section of a jet orifice further improves the jetting capability, and a good jetting effect is achieved.
Description
technical field [0001] The invention relates to the field of high-pressure nozzles, in particular to a bionic spiral high-pressure nozzle used for cleaning filter cloth of a plate and frame machine and a design method thereof. Background technique [0002] In the cleaning and environmental protection industry, high-pressure cleaners are widely used in various fields as an indispensable equipment. It is a machine that uses a power device to drive an internal high-pressure pump to generate high-pressure water to quickly wash away impurities and dirt on the surface of objects. , This cleaning method is also recognized as one of the most convenient, economical, environmentally friendly and scientific cleaning methods in the world. The high-pressure nozzle, as the most important part of the high-pressure cleaner, plays a vital role in the cleaning effect. It is generally installed at the outlet end of the pipeline connected to the high-pressure cleaner, and is changed by adjustin...
