Embodiment Construction

[0021] Such as figure 1 As shown, a novel stainless steel filter includes a cylinder body 1, an upper cover arranged on the upper part of the cylinder body 1, and the upper cover is connected to the cylinder body 1 through a flange. The lower part of the cylinder body 1 is provided with a mounting plate 6, which divides the cylinder body 1 into a filter chamber 2 and a buffer chamber 3, the buffer chamber 3 is located at the lower part of the filter chamber 2, and inside the filter chamber 2, two filter mesh cylinders are arranged side by side 8. The filter screen cylinder 8 is installed on the installation plate 6, and the installation plate 6 is provided with a water inlet hole 7. The water inlet hole 7 communicates with the filter screen cylinder 8, and the filter screen cylinder 8 and the installation plate 6 are detachable. connect. One end of the filter screen cylinder 8 installed on the mounting plate 6 is in the shape of an inverted cone, and the tip of the inverted c...

Abstract

The invention discloses a novel stainless steel filter. The filter comprises a cylinder body, an upper cover arranged on the upper part of the cylinder body, and an installation plate arranged on thelower part of the cylinder body, wherein the cylinder body is divided into a filtration cavity and a buffer cavity by the installation plate, the interior of the filtration cavity is provided with a filtration net cylinder, the filtration net cylinder is installed on the installation plate, a water inlet is arranged on the buffer cavity, a water outlet is arranged on the filtration cavity, a liquid level switch is arranged inside the filtration cavity, the height of the liquid level switch is lower than the height of the water outlet, a gas discharge valve is arranged on the upper cover, and the gas discharge valve communicates with the interior of the cylinder body. The filter has the following beneficial effects: (1) the gas discharge valve is arranged, and the gas discharge valve can beautomatically opened to protect the water inlet system when the internal pressure of the filter is too high; (2) the liquid level switch is additionally arranged, when the filter is blocked, the water level is lower than a designated liquid level, and the running of a water inlet pump group is stopped; and (3) when the filtration net cylinder needs to be replaced, the gas discharge valve is opened to balance the air pressure inside and outside the filter, and thus the replacement is convenient.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a novel stainless steel filter. Background technique [0002] The filter is an indispensable device on the conveying medium pipeline. It is usually installed at the inlet end of the pressure reducing valve, pressure relief valve, and positioning water valve. The existing filter consists of a cylinder, a filter screen, a water inlet, and a drain. Composition, water enters the cylinder through the water inlet, and enters the filter element through the fixed interface. After the water to be treated passes through the filter screen of the filter cartridge, its impurities are blocked, and the filtered water is discharged from the drain. The above-mentioned structure has the following defects during use: [0003] (1) When the filter screen in the cylinder is blocked or there is exhaust gas in the cylinder, the pressure inside the cylinder is too high, causing the fi...
