Submersible self-priming filter head and working method of micro desalination machine

Abstract

The invention relates to the field of seawater desalination, in particular to a submersible self-priming filter head of a miniature desalination machine and a working method. The interior of the filter head shell includes the swirl shell, check valve A, downward sloping baffle, bracket, upward sloping baffle and check valve B from bottom to top; three-stage filtration is performed through 3 cavities from bottom to top, respectively relying on The cyclone separation in the first chamber and the inclined plate settlement principle in the second and third chambers improve the filtering capacity of the filter head and the dirt holding effect of multiple chambers; the support frame can move according to the negative pressure in the filter head It drives the sealing gasket to move up and down, which reduces the chance of clogging the filter head, increases the flow channel area, increases the gravity separation time, avoids the appearance of complex flow field and water flow "dead zone" in the tank, and effectively improves the separation of water and sewage efficiency. The main components in the filter head adopt a detachable structure. Even if there is a blockage, the filter head can be disassembled to quickly clean the internal parts to achieve the effect of quick maintenance.

Description

technical field [0001] The invention relates to the field of seawater desalination, in particular to a submersible self-priming filter head of a miniature desalination machine and a working method. Background technique [0002] The self-priming filter head is a primary filter device connected to the micro-seawater desalination device through a pipeline; during the use of the micro-seawater desalination device, the self-priming filter head needs to be immersed in seawater, and the micro-seawater desalination device passes through the internal plunger pump The expansion and contraction of the seawater pumps the seawater into the seawater desalination device through the filter head and the connecting pipe. During this process, the self-priming filter head plays a role in filtering animals, algae plants and solid particles in seawater. [0003] The existing self-priming filter head adopts a structure in which a filter screen or a ceramic filter core wraps a support frame, and t...

Problems solved by technology

[0004] First of all, the self-priming filter head mainly uses the pores in the filter to realize the separation of water and substances, but the device only filters through the filter, and its treatment effect on small-volume solid particles and suspended matter is not ideal.

[0005] Furthermore, during the filtering process, the dense filter net is likely to cause sediment accumulation in the sea and entanglement of algae plants, resulting in clogging of the filter net surface and affecting the service life of the self-priming filter head

[0006] Secondly, the filter screen or ceramic filter element of the self-priming filter head is usually connected with the structural parts by bonding. Once the blockage caused by sediment accumulation occurs, especially the blockage inside the filter screen, it cannot be repaired by disassembling the self-priming head.
