Problems solved by technology

The filtered residue needs to be slag discharged. The existing slag discharge method is generally to directly open the slag discharge port for slag discharge. However, since the slag discharge valves at the slag discharge port are conventional butterfly valve structures, it is easy to cause slag discharge. The phenomenon of scraping slag, the filter press process before slag discharge is not thorough enough, it is easy to cause waste of materials

Embodiment Construction

[0021] The invention discloses a slag discharge valve combined Figure 1-Figure 2 As shown, it is the same as the prior art, including a valve body 1 and a valve plate 3 placed in the valve body 1 through a valve stem 3 . One end of the valve stem 3 is connected to a driving mechanism 6 arranged outside the valve body 1 , and in this embodiment, the driving mechanism 6 is an air cylinder. The valve plate 3 is driven to rotate by the cylinder to open or close the slag discharge valve.

[0022] Different from the prior art, the back of the valve plate 2 is arranged in an arc shape, and is eccentrically arranged with the valve stem 1, and the eccentric distance is 1-2mm. A groove 11 is provided around the upper surface of the valve plate 2 , and the groove 11 communicates with a counterbore 12 provided on the valve plate 2 . The counterbore 12 and the groove 11 are arranged on the same surface of the valve plate 2 . In this embodiment, the centerline of the groove 11 passes th...

Abstract

The invention provides a deslagging valve and a filter with the same. The deslagging valve comprises a valve body and a valve plate arranged in the valve body through a valve rod, the periphery of the upper surface of the valve plate is provided with a groove, and the groove communicates with a counter bore formed in the valve plate. The deslagging valve has the beneficial effects that when the deslagging valve is used for deslagging of the filter, deslagging can be well carried out, slag scraping is avoided, the thoroughness of filter pressing can be guaranteed, and the filter pressing efficiency is improved.

Description

technical field [0001] The invention relates to a slag discharge valve and a filter with the slag discharge valve. Background technique [0002] The filter is a device that uses a porous filter to achieve solid-liquid separation. At present, the filter has been widely used in chemical industry, petroleum, pharmaceutical, light industry, food, mineral processing, coal and water treatment and other departments. The working principle of the filter is to pump the filtrate into the tank through the liquid inlet pipe through the filter pump and fill it up. Under the action of pressure, the solid impurities in the filtrate are intercepted by the filter screen on the filtrate and form a filter cake on the filter screen. , The filtrate goes through the filter screen and then enters the liquid outlet pipe and flows out of the tank, so as to obtain a clear filtrate. The filtered residue needs to be slag discharged. The existing slag discharge method is generally to directly open the s...
