Pressure release nozzle applied to filtering machine

Abstract

The invention discloses a pressure release nozzle applied to a filtering machine. The pressure release nozzle comprises a nozzle pipe. A water outlet is formed in the side wall of the nozzle pipe. An annular valve seat is connected into the nozzle pipe in an inserted manner. Multiple water outlet grooves different in width are formed in the valve seat. The water outlet grooves are opposite to the water outlet in the nozzle pipe. A pressure release pipe is formed at the position, between the lower side of the upper end face of the valve seat and the upper side of the water outlet, on the nozzle pipe. A vertical guide pillar is formed on the lower end face of the valve seat. The lower end of the guide pillar penetrates an inverted-T-shaped end cover to form a ring table. The ring table abuts against the lower end face of the end cover in a pressing manner. The end cover is in screw joint to the bottom end of the nozzle pipe. The guide pillar is sleeved with a compression spring in an inserted manner. The two ends of the compression spring abut against the end cover and the valve seat correspondingly in a pressing manner. The pressure release nozzle is simple in structure, the water outlet flow of the nozzle can be mechanically adjusted conveniently, meanwhile, the nozzle can be demounted, and cleaning is convenient.

Description

[0001] Technical field: [0002] The invention relates to the technical field of chemical equipment, in particular to a pressure relief nozzle applied to a filter. [0003] Background technique: [0004] At present, the horizontal vacuum filter used in solid-liquid separation in China requires a washing device to repeatedly spray and wash the material when filtering the material. Since the washing water used for washing is process water (process water), it contains more impurities. , the nozzle is easy to block, so the water output of the nozzle needs to be adjusted. At present, the water flow rate of the nozzle in the horizontal vacuum filter for solid-liquid separation can only be controlled by a regulating valve, which is cumbersome and will increase production costs. In addition, after the existing nozzles are worn out, the entire nozzles need to be removed and replaced with new ones, which will undoubtedly bring about large maintenance costs.
