Anti-blocking type slag discharging system for slag scraper

Abstract

The invention discloses an anti-blocking type slag discharging system for a slag scraper. The anti-blocking type slag discharging system comprises a slag collecting box; the inner wall of the slag collecting box is fixedly connected with a first circular ring; the inner wall of the first circular ring is fixedly connected with a second circular ring through a fixing rod; a filter screen is fixedlyconnected between the first circular ring and the second circular ring, the inner wall of the second circular ring is slidably connected with a slag discharging cylinder, the lower end of the slag discharging cylinder penetrates through the lower end of the slag collecting box and is slidably connected with the side wall of the slag collecting box, the slag discharging cylinder and the inner wallof the slag collecting box form a drainage chamber, and a driving mechanism for driving the slag discharging cylinder to rotate is mounted in the drainage chamber. When the gravity of sewage in a V-shaped plate reaches the critical value of a pressure release valve, sewage in the V-shaped plate is rapidly sprayed out from the pressure release valve, a water wheel is driven to rapidly rotate, andthen the slag discharging cylinder is driven to rapidly rotate, so that a permanent magnet column periodically skims over the lower end of an ejector pin, the ejector pin continuously ejects upwards to dredge waste slag, the blockage phenomenon is effectively prevented, and sewage treatment is accelerated.

Description

technical field [0001] The invention relates to the technical field of slag scrapers, in particular to an anti-blocking slag discharge system for slag scrapers. Background technique [0002] In the sewage treatment process, the slag scraper is mostly used to scrape the waste slag at the upper end of the air flotation tank to achieve the purpose of sewage purification. [0003] When the slag scraper is running, the slag scraper installed on the slag scraper will reciprocate to scrape off the slag on the water surface of the air flotation pool, and when the slag scraper moves to separate from the upper end of the air flotation pool, the slag on the slag scraper will be It flows into the slag discharge chamber fixedly connected to the slag scraper, and is discharged through the slag discharge pipe. Since there are many types and large amounts of impurities in the waste slag, when the waste slag is discharged through the slag discharge pipe, it is easy to cause blockage in the s...

Problems solved by technology

[0003] When the slag scraper is running, the slag scraper installed on the slag scraper will reciprocate to scrape off the slag on the water surface of the air flotation pool, and when the slag scraper moves to separate from the upper end of the air flotation pool, the slag on the slag scraper will be It flows into the slag discharge chamber fixedly connected to the slag scraper, and is discharged through the slag discharge pipe. Since there are many types and large amounts of impurities in the waste slag, when the waste slag is discharged through the slag discharge pipe, it is easy to cause blockage in the slag discharge pipe. As a result, the waste slag cannot be discharged, which is not conducive to sewage treatment. At present, most of the dredging of the slag discharge pipeline is manual dredging, the dredging intensity is relatively high, and the peculiar smell in the waste residue is relatively large, which will easily cause discomfort to the dredging personnel.
