Abstract
The utility model relates to an electric scrapper assembly for a self-cleaning filter sieve. The electric scrapper assembly comprises a scraper assembly with a scraper, a driving mechanism of the scraper assembly and a drive control device, wherein the scraper assembly comprises a scraper frame with a frame structure, and the scraper frame is arranged rotatably; and the scraper frame is provided with a scraper fixing rod parallel to the axis of a filter screen barrel of a filter sieve, and the scraper is fixed on the scraper fixing rod; and the driving mechanism comprises a motor and a main transmission shaft, wherein the motor is driven by one end of the main transmission shaft and connected with one end of the main transmission shaft, and the other end of the main transmission shaft is connected with the scraper frame. The scraper is fixed on the scraper fixing rod which is arranged on the scraper frame and parallel to the axis of the filter screen barrel of the filter sieve, and the scraper frame is arranged rotatably, so that the drive control device can be used for controlling the scraper assembly to slide along the surface of the filter screen barrel according to a fixed-time or differential pressure condition to remove impurities on the surface of the filter screen barrel, and then, the long-term filtering function of a filter screen is kept.
Description
Technical field
The utility model relates to a kind of doctor assemblies of the filter for separating of fluid impurity, is specially self-cleaning sieves electric scraper assembly.
Background technology
Sieves is a kind of equipment of removing small amount of solid impurity in the liquid; can protect the operate as normal of equipment such as sprinkling equipment, nozzle, compressor; be provided with filter cylinder in the sieves; after entering the filter cylinder that has only the certain specification screen cloth when liquid; impurity wherein is blocked, and the filtrate of cleaning is then flowed out by the sieves outlet and reached the filtration purpose.Sieves all is widely used in fields such as industrial circulating water, raw water filtration, petroleum industry, chemical filtration and environment-friendly engineerings.But the filter of Shi Yonging is not owing to there is the automatically clearing impurity function in the market, after use after a while, impurity can be blocked the filter opening of filter cylinder, causes filter efficiency to reduce, can not keep the strainer filtering function for a long time, when serious even can't operate as normal.
Summary of the invention
The purpose of this utility model is to provide a kind of and can remove screen surface impurity automatically for overcoming the deficiencies in the prior art, keeps the self-cleaning sieves electric scraper assembly of strainer filtering function for a long time.
For achieving the above object, the technical solution that the utility model adopts is as follows: a kind of self-cleaning sieves electric scraper assembly, comprise the doctor assemblies and driving mechanism and the driving control device that have scraper, it is characterized in that: described doctor assemblies comprises the doctor blade holder of a frame structure, the rotatable setting of described doctor blade holder; Described doctor blade holder is provided with the scraper fixed bar that parallels with the screen tube axis of sieves, described scraper is fixed on the scraper fixed bar, described driving mechanism comprises motor and transmission main shaft, and described motor and transmission main shaft one end are in transmission connection, and the transmission main shaft other end is connected with described doctor blade holder.
Beneficial effect compared with prior art is: because the described scraper of utility model is fixed on the scraper fixed bar that parallels with the screen tube axis of sieves on the doctor blade holder, the rotatable setting of described doctor blade holder, therefore, driving control device can slide the lip-deep Impurity removal of screen tube along the screen tube surface by timing differential pressure condition control doctor assemblies, to keep the long filtering function of filter screen.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
