Embodiment 1

[0009] Embodiment 1: with reference to attached figure 1 . A special nano-filter plate forming mold for filter presses, which includes an upper mold 3 and a lower mold 1. There are multiple heating channels around the lower mold 1 and heating elements 4 are built in the heating channels. The molding surface of the upper mold 3 A plurality of nozzles 8 are provided and the nozzles 8 communicate with the nano pressurizer 6 through the fluid channel 5 in the upper mold 3 body. The manufacture of the upper mold 3 and the lower mold 1 is a prior art, and will not be described here. Nano pressurization (jet) device 6 is prior art, does not describe at this.

[0010] The heating element 4 is an electric heating tube or an electric heating wire, and the installation of the electric heating tube or the electric heating wire and the heating channel in the lower mold 1 and the design of the electric heating tube or the electric heating wire terminal connected to the power control end of...

Embodiment 2

[0013] Embodiment 2: On the basis of embodiment 1, the molding method of the special nano-filter plate molding die for filter press, first the filter plate plate material after forming is placed in the lower membrane 1 after heating, when the filter plate in the lower mold cavity When the plate material has just passed the critical point of melting, start the nano pressurizer 6, and the multiple nozzles 8 on the forming die surface of the upper mold 3 above the lower mold 1 spray the nano material onto the surface of the filter plate material, and then pressurize Close the upper mold 3, force the nano-layer sprayed on the filter plate to merge into the surface of the filter plate to form a nano-layer 7, and obtain the nano-filter plate after cooling. The pressure ejected from the nozzle 8 is greater than or equal to the pressure exerted by the upper die on the filter plate. The nano material is nano ceramic powder, nano metal material. The nanolayer is larger than 0.1 microns...

Abstract

The invention relates to a nanometer filter plate forming mould special for a filter press, capable of combining nanometer materials on the extrusion face of a filter plate, and a forming method of the mould. The nanometer filter plate forming mould comprises an upper mould and a lower mould, wherein the periphery of the lower mould is provided with a plurality of heating channels, and the heating channels are internally provided with heating elements; the forming mould surface of the upper mould is provided with a plurality of nozzles, and the nozzles are communicated with a nanometer pressurizer through fluid channels inside an upper mould body. The invention has the advantages that: not only the manufacture of a nanometer filter plate is realized, but also the nanometer materials can be effectively fused into the filter plate; the manufactured nanometer filter plate has the advantages of ultrahigh stain resistance, smooth and delicate surface, difficult dust and greasy dirt adsorption and easiness in cleaning, can not only enable squeezed filter cakes to automatically drop from the nanometer filter plate, but also enable the nanometer surface to have good stain-resistant characteristic; the manufactured nanometer filter plate has ultrahigh abrasion resistance, thereby obviously enhancing the rigidity of the filter plate; in addition, the manufactured nanometer filter plate has ultrahigh electrostatic resistance, thereby effectively eliminating the electrostatic phenomenon without adsorbing dust particles.

Description

technical field [0001] The invention relates to a special nanometer filter plate molding die for a filter press capable of combining nanometer materials on the extrusion surface of a filter plate and a molding method, belonging to the field of filter plate molding mold manufacturing for a filter press. Background technique [0002] At present, the special filter plate molding mold for filter press adopts hot runner mold injection molding. During the hot runner mold molding process, the temperature of the plastic melt is accurately controlled in the runner system. The plastic can flow into each cavity in a more uniform state, resulting in parts with consistent quality, and the parts formed by the hot runner have good gate quality, low residual stress after demolding, and small deformation of the parts. However, it cannot be used for forming nano-filter sheets. Contents of the invention [0003] Design purpose: To avoid the deficiencies in the background technology, to desi...
