Example Embodiment

[0037] Example 1

[0038] This embodiment provides a device for fully automatic filtering sodium vanadate crystals. The device includes a kettle body and a housing 7. The kettle body is provided with a filter plate 5, and a filter cloth is distributed between the filter plates 5. The kettle body is respectively provided with a feed port 1, a liquid outlet 9, and a discharge port 12 at the bottom of the kettle body and a steam blowback port 3 at the top of the kettle body.

[0039] Further, the device also includes an air-dried gas inlet 4 at the top of the kettle body and a sewage outlet 13 at the bottom of the kettle body, as well as an observation port 6, a pressure sensing device 8 and a plate repair flange 10 located on the kettle body.

[0040] Further, a liquid outlet pipe 2 connected to a liquid outlet is provided in the kettle body, and the liquid outlet pipe 2 is connected with a steam blowback port 3. A feed pipe is provided in the kettle body, and a filtrate cloth inlet 11 i

Example Embodiment

[0041] Example 2

[0042] This embodiment provides a method for fully automatic filtering sodium vanadate crystals, using the device provided in Example 1. The method is: introducing the mixed slurry obtained after sodium vanadate crystallization from the feed port 1. The filtrate is evenly distributed through the cloth inlet 11 on the feed pipe and then enters the filter plate 5 for filtration. At this time, except for the inlet 1 and the liquid outlet 9, all other inlets and outlets communicating with the outside are closed. After the filtration is completed, the sodium vanadate crystals remain on the filter cloth of the filter plate 5, and the liquid is discharged from the liquid outlet 9 through the liquid outlet pipe 2. In the process of filtering, the content of crystals in the device is determined through the observation port 6 and the pressure sensing device 8. When the crystal content is constant, close the feed inlet 1 and the liquid outlet 9, and open the sewage 13 and th

Abstract

The invention relates to a device and method for fully automatically filtering sodium vanadate crystals. The device comprises a kettle body and a shell, wherein a filter plate is arranged in the kettle body; a feeding hole and a liquid outlet as well as a discharging hole and a steam blowback port are respectively formed in the kettle body; the discharging hole is formed in the bottom of the kettle body; and the steam blowback port is formed in the top of the kettle body. According to the device and method disclosed by the invention, discharging is performed by utilizing a steam blowback method, the whole discharging process is fully automatically performed, a plate frame does not need to be opened to perform manual or mechanical discharging or clean the filter surface, and the problems ofdifficulty in discharging the sodium vanadate crystals and carrying out the continuous filtration because filter cloth gaps are blocked by the crystals are solved. The whole discharging process can be automatically performed, so that the filtering efficiency is greatly improved, and the manual cost is reduced, and the device and the method have excellent economic benefits and application prospects.
