specific Embodiment approach 1

[0025] Combine below figure 1 , 2 , 3, 4, 5, 6, and 7 illustrate this embodiment, a sewage treatment device with multi-stage filtration, including an outer pipe 1, a primary filter 2, an impeller 3, an axle 4, a taper sleeve 5, and a suction closure 6 , semicircular filter screen I7 and semicircular filter screen II8, the primary filter screen 2 is fixedly connected to the left end inside the outer tube 1, the tapered sleeve 5 is fixedly connected to the inside of the outer tube 1, the semicircular filter screen I7 and semicircular filter screen II8 Both are fixedly connected to the right end of the outer tube 1, the semicircular filter I7 and the semicircular filter II8 form a circular filter, the suction-back closure 6 is rotatably connected to the left end of the taper sleeve 5, the impeller 3 and the suction-back closure Parts 6 are respectively fixedly connected to the left and right ends of the wheel shaft 4; when in use, the sewage flows from left to right through the ...

specific Embodiment approach 2

[0027] Combine below figure 1 , 2 , 3, 4, 5, 6, and 7 illustrate this embodiment, and this embodiment will further describe Embodiment 1. The inside of the taper sleeve 5 is fixedly connected with a motor 9, and the axle 4 is connected to the motor 9 through a coupling. on the transmission shaft; when the sewage discharge flow rate is small, the motor 9 can be used to drive the wheel shaft 4 to rotate, thereby realizing the rotation of the impeller 3 and the suction closure 6, and the motor 9 drives the impeller 3 to actively rotate, and then the impeller 3 accelerates the sewage The flow flowing from left to right makes it easier for the sewage to impact on the semicircular filter Ⅰ7 and semicircular filter Ⅱ8, which not only improves the filtration efficiency, but also reduces debris blocking the filter holes on the semicircular filter Ⅰ7 and semicircular filter Ⅱ8; at the same time The motor 9 drives the suction-back sealing member 6 to rotate, which solves the problem tha...

specific Embodiment approach 3

[0029] Combine below figure 1 , 2 , 3, 4, 5, 6, and 7 illustrate this embodiment, and this embodiment will further illustrate Embodiment 1. The outer pipe 1 includes a water inlet pipe 1-1, a variable diameter conduit 1-2 and an outlet pipe 1-3, The diameter-reducing conduit 1-2 is fixedly connected to the right end of the water inlet pipe 1-1, and the water outlet pipe 1-3 is fixedly connected to the right end of the diameter-reducing conduit 1-2; the diameter of the water inlet pipe 1-1 is larger than that of the water outlet pipe 1 -3 caliber, so that larger debris can be accommodated in the water inlet pipe 1-1, which is convenient for sewage to enter. The filter holes on the filter screen I7 and the semicircle filter screen II8.

Abstract

The invention relates to a sewage treatment device, more specifically a multi-stage filtration sewage treatment device, which includes an outer pipe, a primary filter, an impeller, a wheel shaft, a cone sleeve, a suction closure, a semicircular filter I and a semicircular Filter screen II, the primary filter screen is fixedly connected to the left end of the outer tube, the taper sleeve is fixedly connected to the inside of the outer tube, the semicircular filter screen I and semicircular filter screen II are fixedly connected to the right end of the outer tube, and the semicircular filter screen II is fixedly connected to the right end of the outer tube. The filter screen I and the semicircular filter screen II form a circular filter screen, the suction-back sealing part is rotatably connected to the left end of the taper sleeve, and the impeller and the suction-back sealing part are respectively fixedly connected to the left and right ends of the axle. The invention can realize two-stage filtration of sewage; when the sewage flow is small, the impeller can be actively rotated to increase the sewage flow; it can realize intermittent reverse suction on the semicircle filter net I or semicircle filter net II to avoid impurities Block the filter holes on half-round filter I and half-round filter II.

Description

technical field [0001] The invention relates to a sewage treatment device, more specifically a sewage treatment device with multi-stage filtration. Background technique [0002] For example, a multi-channel sewage filtering device whose patent application number is CN201010139334.9 is mainly composed of a housing and a cylindrical filter screen. The multi-channel sewage filtering device is provided with at least one double-screen filter unit. The double-screen filter unit includes: the housing is a sealed housing, the middle part of the housing is a filter chamber, the upper side of the filter chamber is a filter front chamber, and the lower side of the filter chamber is separated by a top cover to form a self-cleaning chamber. In the dirty room, the cylindrical filter is a cylindrical filter with openings at both ends. The cylindrical filter runs through the upper and lower ends of the rear chamber, and the secondary filter is a cylindrical filter with openings at both ends...
