Embodiment 1

[0042] like Figure 1-Figure 3 A pre-filter shown is composed of housing 1 , brush 3 , filter element 2 and other components. The housing 1 is cylindrical and has oppositely arranged water inlet and water outlets on its upper outer peripheral surface. The top of the inner cavity of the housing 1 is fixedly connected with a mounting seat 5, and the lower end of the housing 1 is also provided with a housing 1 The sewage discharge end 12 that the inner chamber communicates with the outside. The side of the mounting base 5 has a connection port docked with the water outlet, the lower end of the mounting base 5 is open, and the filter element 2 is connected to the opening, so that when the water inlet end enters the water, the water flow can fill the entire inner cavity of the housing 1 and flow into it. In the inner cavity of the filter element 2, when water flows through the filter element 2, the impurities in the water flow are isolated by the filter element 2 and left on the o...

Embodiment 2

[0049] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that the valve stem 4 in this embodiment is directly fixedly connected with the connector 21 on the filter element 2, and the valve stem 4 is slidably arranged in the mounting seat 5 , realize the rotation by connecting with an external controller, and achieve the same technical effect as that of Embodiment 1.

Abstract

The invention provides a pre-filter, belonging to the technical field of filters. The pre-filter solves the problem that cleaning and pollution discharge in an existing pre-filter are inconvenient. The pre-filter comprises a shell with a blow-off end; a cylindrical filter element is arranged in the shell; a brush piece wraps the peripheral surface of the filter element; a valve rod capable of driving the filter element to rotate is arranged in the shell in a penetrating mode; a threaded section is arranged on the upper portion of the filter element; a threaded part matched with the threaded section is arranged in the shell; the lower end of the filter element abuts against a blow-off end to realize sealing; and the filter element can rotate to enable the threaded section and the threaded part to be disengaged and matched. According to the pre-filter, the filter element is scraped and washed in a rotating mode through threaded connection of the filter element and the shell, and meanwhile, the pollution discharge end is opened for pollution discharge,so through the design, the internal cleaning convenience degree of the pre-filter is greatly improved; and the controller can be connected to the exterior of the shell to control the valve rod to rotate forwards and backwards at a fixed time and a fixed speed, so full-automatic internal cleaning and pollution discharge of the pre-filter are realized.

Description

technical field [0001] The invention belongs to the technical field of filters, and relates to a filter, in particular to a pre-filter. Background technique [0002] Existing pre-filters generally include a housing with a water inlet and an outlet and a sewage discharge end. The housing is generally provided with a fixed filter core. It consists of a filter screen on the surface, and the outside of the filter element is equipped with brushes that can scrape and wash impurities on the filter screen by rotating. The existing pre-filter is generally equipped with a hand wheel outside the sewage end, the hand wheel is connected to the brush through a connecting piece that is circumferentially sealed with the sewage end, and the brush is manually rotated by turning the hand wheel to adjust the filter element. The filter is scraped and cleaned. There is often a ball valve core on the connecting piece, which can open the sewage end by twisting the ball valve core, and then enter ...
