Embodiment 1

[0027] in such as figure 1 In the shown embodiment 1, an inclined reversible filter device includes an inclined cylinder 1 and a filter plate 2 arranged in the cylinder, and the angle between the axial direction of the cylinder and the horizontal plane is 45 to 60 degrees (45 degrees in this embodiment), the filter plate includes a rectangular frame and a filter screen arranged in the frame, the rectangular frame is fixed on the axial center surface of the cylinder, the filter plate The outer edge is in close contact with the inner wall of the cylinder. The inner cavity of the cylinder above the filter plate forms the water inlet cavity 3, and the inner cavity of the cylinder below the filter plate forms the water outlet cavity 4. There is an inlet cavity on the side of the upper end of the cylinder. The water inlet 5 is provided with a water outlet 6 on one side of the water inlet cavity on the lower end surface of the cylinder, the water inlet is arranged on the upper edge o...

Embodiment 2

[0035] in such as image 3 In the shown embodiment 2, the filter plate includes a rectangular surrounding frame 10 and a filter screen arranged in the surrounding frame. Roller 12, grid-shaped backguy equidistantly arranges, and every grid-shaped backguy is all provided with a plurality of cylindrical rollers (see Figure 4 ), and the rest are the same as in Example 1.

[0036] The filtering method of the inclined type reversible filter device of embodiment 2, except the step of embodiment 1, also comprises the following steps:

[0037] f. When the sundries above the filter plate fall down along the slope of the filter plate, the rollers roll.

Abstract

The invention discloses an inclined turnover filter device and a filtering method. The inclined turnover filter device comprises an inclined cylinder and a rectangular filter plate arranged on an axial central surface in the cylinder, wherein the inner cavity of the cylinder above the filter plate forms a water inlet cavity; the inner cavity of the cylinder below the filter plate forms a water outlet cavity; a water inlet is formed in the water inlet cavity side of the upper end surface of the cylinder; a water outlet is formed in the water outlet cavity side of the lower end surface of the cylinder; sundry outlets are formed in the water outlet cavity side of the upper end surface of the cylinder and the water inlet cavity side of the lower end surface of the cylinder; a rotating shaft ishorizontally fixed to the centers of the two sides of the cylinder; the cylinder is rotatably arranged on a machine frame through the rotating shaft. The inclined turnover filter device effectively solves the problems that the filter device in the prior art easily causes dirt accumulation, a filter screen needs to be frequently cleaned, and thus manpower and material resources are wasted; the inclined turnover filter device is simple in structure, can automatically clean the filter screen by backflushing, and has a very high practical value.

Description

technical field [0001] The invention belongs to the technical field of aquaculture filtering devices, and in particular relates to a tilting reversible filtering device and method for filtering large particle impurities at the primary stage of a filtering system. Background technique [0002] At present, marine aquaculture often needs to build a breeding pond, and then introduce seawater, and seawater often contains debris and sediment, so it needs to be filtered before seawater enters the breeding pond, and the current seawater filtration mainly uses filter mesh and natural precipitation and other treatment methods. Because the filter screen is easy to accumulate sundries, it needs to wash the filter screen frequently, which is time-consuming and laborious; natural sedimentation requires a relatively large sedimentation tank and a long sedimentation time. The publication date is June 8, 2016, and the Chinese patent document with the publication number CN205284659U disclose...
