Detailed Description

Example 1

Referring to fig. 1 to 5, a concrete wastewater treatment device comprises a fourth water tank 14, a first cover plate 31 is fixedly arranged on the front side of the fourth water tank 14, a second cover plate 32 is movably arranged on the rear side of the fourth water tank 14, a notch is arranged on the second cover plate 32, the notch is matched with the first cover plate 31, and the first cover plate 31 and the second cover plate 32 are spliced into a covering part. The first cover plate is in a fixed state, the second cover plate is in a movable state, for example, as shown in fig. 2 and 3, when the first cover plate is placed, the notched end of the second cover plate is lapped at the rear part of the fourth water tank, and then the second cover plate is integrally moved forwards, so that the notch of the second cover plate is jointed with the first cover plate. The first cover plate and the second cover plate are combined into an integral covering part, so that foreign matters can be prevented from entering the pool.

The first cover plate 31 is provided with a through hole, the upper side of the through hole is provided with a cylinder 41, the drain pipe 5 (which can be made of stainless steel and other materials) penetrates through the cylinder 41 and the through hole and extends into the fourth water tank 14, and the side surface of the cylinder 41 is provided with a bolt 42 for fixing the drain pipe. The side of the barrel is provided with a threaded hole, a bolt is arranged in the threaded hole, and the end part of the bolt is used for fixing the drain pipe in the barrel.

Wherein, a water tank 14a is arranged at the bottom of the fourth water tank 14 and below the drain pipe 5, the inner diameter of the water tank 14a is larger than the outer diameter of the drain pipe 5, and a filter screen 6 (made of stainless steel and other materials) is arranged at the bottom of the drain pipe 5.

The top of the drain pipe can be provided with a connecting piece such as a flange, is connected with the flexible connecting pipe and then is connected with the water pump. When the water at the bottom of the pool needs to be discharged in the process of cleaning the fourth pool, the bolts are loosened, the drain pipe is pressed downwards, so that the bottom of the drain pipe is pressed into the water tank, and the drain pipe is fixed through the bolts after the water tank is adjusted in place. By the method, the water at the bottom of the pool can be discharged, and the cleaning effect is improved. It should be noted that, in the downward adjustment process, the bottom of the drain pipe should have a certain distance from the bottom of the sink to prevent blockage. After completion, the drain pipe is adjusted upward to a normal state, and the height of the bottom of the drain pipe (normal use height) in fig. 4 is taken as an example and can be adjusted as required.

Example 2

The basic structure is the same as that of embodiment 1, except that a plurality of convex rods are arranged on the filter screen 6 (see fig. 5, the bottom view of the convex rods is schematically shown at the black round points in the figure). The length of the convex rod is less than the depth of the water tank. The convex rod can improve the convenience of use, and the convex rod supports the bottom of the water tank in the downward adjustment process, so that the blockage at the bottom of the drain pipe caused by the over-limit adjustment can be avoided, and the drainage is facilitated.

Preferably the length of the protruding rod is half the depth of the water channel. Is beneficial to use.

Particularly, when the bottom of the water tank is provided with the fragile block-shaped bodies and other impurities, the impurities and the like can be punctured to a certain extent through the convex rods, and the water tank is beneficial to discharging.

Example 3

The basic structure is the same as that of embodiment 1 or embodiment 2, the difference is that the through hole in the first cover plate and the central hole in the barrel jointly form a via hole, and after the drain pipe is fixed, an air passage is arranged between the via hole and the drain pipe (the inner diameter of the via hole is larger than the outer diameter of the drain pipe, for example, the inner diameter of the via hole is 0.3-0.5cm larger than the outer diameter of the drain pipe), so that the inside of the fourth water pool is communicated with the external environment, and the use of the device.

Above only do the preferred embodiment of the present invention, the protection scope of the present invention is not limited to the above embodiment, all belong to the technical scheme of the present invention all belong to the protection scope of the present invention. For those skilled in the art, several modifications can be made without departing from the principle of the present invention, and such modifications should also be considered as the protection scope of the present invention.
