Problems solved by technology

The disadvantages of ceramic filter plates are: high cost of use, mainly due to high cleaning costs, complex structure of the whole machine, need to be equipped with pickling and ultrasonic systems, which pollute the environment; easy to block, short service life, low mechanical strength, backwashing and suction It is easy to break in vacuum and is not resistant to low temperature; and due to the limitation of materials, the filter area cannot be too large, so the whole machine cannot be enlarged

Embodiment 1

[0043] as attached figure 1 , 2 As shown, the present invention provides a high-pressure filter, the structure of which includes a trough 200 filled with slurry, a filter disc 300 built in the trough 200, and a power device 400 that drives the filter disc 300 to rotate around its own axis. A sealed shell 210 is arranged outside the trough 200. The inner wall of the sealed shell 210 is connected with the outer wall of the trough 200 to form a sealed cavity 220. The surface of the sealed shell 210 is provided with a liquid inlet 230 connected to the sealed cavity 220. The position of the liquid inlet 230 is installed There is an ultrasonic liquid level controller a.

[0044] as attached Figure 3-6 As shown, in order to achieve good filtration, the structure of the filter disc 300 specifically includes a screw shaft 310 and 12 filter disc bodies 320 . The two ends of the screw shaft 310 pass through the bearing seat outwards out of the sealed casing 210, the end of the screw ...

Embodiment 2

[0052] combined with Figure 1-6 , refer to attached Figure 7 , the difference from Embodiment 1 is that: the number of screw shafts 310 is at least two. Taking Embodiment 1 as a reference, the number of screw shafts 310 should be twelve. The rightmost screw shaft 310 is connected to the power unit 400, the rightmost screw shaft 310 has an axial hole 311, and the rest of the screw shafts 310 have an axial through hole 313, and the adjacent screw shafts 310 are arranged in series and threaded to form a straight filter channel ; The number of filter disc bodies 320 is the same as the number of screw shafts 310 , and the filter disc bodies 320 and screw shafts 310 are relatively fixed one by one.

[0053] The filter involved also includes a backwashing system 100, the opening and closing of the backwashing system 100 is controlled by the PLC system, the backwashing system 100 is located at the end of the axial hole 311 of the screw shaft 310, and the water outlet of the backwas...

Abstract

The invention provides a high-pressure filter and belongs to the technical field of filter devices. The filter comprises a trough, a filter disc arranged in the trough, a power device for driving thefilter disc to rotate, a spiral stirring device and a compressed air storage tank. A sealing shell is arranged on the outer side of the trough, the sealing shell and the trough are connected to definea sealing cavity, a liquid inlet communicated with the sealing cavity is formed in the surface of the sealing shell, and an ultrasonic liquid level controller is installed at the position of the liquid inlet. The filter disc further comprises a screw shaft and a filter disc body; wherein the end of the screw shaft outwards penetrates out of the sealing shell, an axial hole is formed in one end face of the screw shaft, and a radial hole communicated with the axial hole is formed in the surface of the screw shaft. The filter disc body is fixed to the screw shaft, the radial hole is formed in the fixed connection position of the filter disc body and the screw shaft, and filtrate flowing into the filter disc body enters the axial hole through the radial hole of the screw shaft and is discharged out of the sealed cavity. The spiral stirring device is arranged in the bottom of the trough; and the compressed air storage tank is arranged outside the sealed shell and is communicated with the sealed cavity. By means of the filter, filtration in a high-pressure environment can be realized.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a high-pressure filter. Background technique [0002] Ceramic filter is a new type, high-efficiency and energy-saving solid-liquid separation equipment commonly used in the world. The ceramic filter is mainly composed of a roller system, a stirring system, an ore supply and discharge system, a vacuum system, a gas distribution system, a filtrate discharge system, a scraping system, a backwash system, a combined cleaning (ultrasonic cleaning, automatic acid cleaning) system, a full It is composed of automatic control system, tank body and rack. The core part of the filter is the ceramic filter plate. The ceramic filter plate is also called ceramic filter membrane, ceramic plate, ceramic plate, filter plate, etc. It is a new type of filter medium made of corundum, silicon carbide, etc. through special processes. The disadvantages of ceramic filter plates are: high cost of use, ma...
