Embodiment 1

[0018] Such as figure 1 As shown, the present invention provides a fully automatic external scraper filter, including a motor 11 and a cylinder 14. The interior of the cylinder 14 is equipped with a main shaft 1, a fixed sleeve 2 and a rotating sleeve 5, and the top of the cylinder 14 is decelerated The machine support 13 is equipped with a reducer 12, the upper end of the cylinder 14 is provided with a feed port 16, the bottom of the cylinder 14 is provided with a discharge port 17, and one side of the lower end of the cylinder 14 is equipped with a blowdown valve 15, and the motor 11 passes through the deceleration. The machine 12 is in transmission connection with the main shaft 1, and the main shaft 1 is equipped with a plurality of evenly distributed scrapers 7 through the first scraper clamping plate 6 and the second scraper clamping plate 8.

[0019] There are 3 groups of scrapers 7 and they are evenly distributed at 120 degrees, and each group is equipped with 6 scrape...

Abstract

The invention discloses a fully automatic external scraper filter. The filter comprises a cylinder, a main shaft, a fixed sleeve and a rotating sleeve are installed in the cylinder, the top of the cylinder is provided with a gear reducer through a gear reducer support, the upper end of the cylinder is provided with a feeding inlet, the bottom of the cylinder is provided with a discharge outlet, a pollution discharge valve is installed on one side of the lower end of the cylinder, a motor is in transmission connection to the main shaft through the gear reducer, and the main shaft is provided with evenly distributed scrapers through a first scraper clamping plate and a second scraper clamping plate. The filter removes impurities from the surface of a filter screen by an efficient mechanical scraping method so that the filter screen has a good filtering function. A spring compensator is arranged between the scrapers and the main shaft so that the scraper cannot tightly or loosely fit to the filter screen. When the scraper too tightly fits to the filter screen, a service life of the filter screen is influenced and when the scraper too loosely fits to the filter screen, screen surface impurities cannot be fully removed. Through the spring compensator, the screen surface impurities can be effectively scraped and removed and the filter screen and scrapers can be protected.

Description

technical field [0001] The invention relates to a scraper filter, in particular to a fully automatic external scraper filter, which belongs to the technical field of mechanical equipment. Background technique [0002] The existing scraper filter structure is composed of a motor, a reducer, a reducer motor bracket, a housing, a filter screen, a sewage valve, a main shaft, a scraper and a control cabinet. The principle is to scrape the surface of the filter screen The impurities are removed, and the filter screen is automatically cleaned through intelligent control (time and pressure difference) and the impurities are discharged from the sewage outlet. The scraper of the cleaning device is installed in the tank. When the impurities on the filter screen accumulate to a certain extent, the pressure difference starts, and the geared motor drives the internal scraper device to rotate to remove the impurities on the surface of the filter screen. However, the problem with the curren...
