Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0012] Such as Figure 1-2 As shown, a pouring nozzle 2 is set at the bottom of the traditional curtain film pouring tank 1, and the pouring nozzle is connected to the pouring box 4 through the pouring pipe 3, and the epoxy resin castable is poured into the pouring box quantitatively, so that the pouring material can rely on itself Gravity flows into the pouring trough from the pouring nozzle at the bottom of the pouring trough, and there is a layer of isolation plate with many round holes (the diameter of the round hole is 3mm) in the pouring trough, so that the pouring material overflows the isolation plate from the bottom of the pouring trough through the small holes until it is fu...

Abstract

The invention discloses a novel flat-plat membrane pouring process. The novel flat-plat membrane pouring process is characterized in that a pouring gate is formed at the bottom part of a traditionalflat-plat membrane pouring trough and connected with a refractory castable box through a refractory castable pipe; a certain amount of epoxy resin refractory castable is poured into the refractory castable box for enabling the refractory castable to flow into the pouring trough from the pouring gate at the bottom part of the pouring trough by relying on the self-gravity of the refractory castable;and a layer of partition board with a plurality of round holes is arranged in the pouring trough for enabling the refractory castable to overflow out of the partition board from the bottom part of the pouring trough through the small holes until the whole pouring trough is fully filled. The novel flat-plat membrane pouring process avoids the phenomenon that the epoxy resin adhered to membrane wires caused by being poured from the top cannot be removed.

Description

technical field [0001] The invention relates to the field of water treatment equipment, and more specifically relates to a novel curtain membrane casting process. Background technique [0002] The conventional curtain film casting process is to pour epoxy resin and other castables from the top of the pouring trough, so that it flows into the bottom of the pouring trough by gravity, and finally fills the pouring trough. The conventional curtain membrane casting process has problems such as uneven pouring, voids and easy adhesion of membrane filaments. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a novel curtain film casting process. [0004] A novel curtain film casting process of the present invention is realized through the following technical scheme. A pouring nozzle is arranged at the bottom of a traditional curtain film pouring tank, and the pouring nozzle is...
