Example 1:
as shown in fig. 1 to 6, the sewage treatment sampling assembly provided in this embodiment includes a water pump 1, a sewage collection container 2, and a filter head 5, wherein:
the water pump 1 and the sewage collection container 2 are both installed on the sewage sampling device, and the water pump 1 is electrically connected to a power supply, thereby supplying water with power by the power supply. In this embodiment, since the sewage sampling device is the prior art, detailed description thereof is not provided here.
The sewage collecting container 2 is a bottle-shaped structure, and is connected with the water outlet of the water pump 1 through the first water pipe 3, so that when the water pump 1 operates, sewage can be pumped into the sewage collecting container 2. The sewage collecting container 2 is detachably mounted on the sewage sampling device, so as to facilitate the taking.
The filter head 5 is connected with the water inlet of the water pump 1 through the second water pipe 4 so as to filter the sewage entering the second water pipe 4, and particularly prevent most of solid floaters in the sewage from entering the second water pipe 4. Wherein, filter head 5 includes seal shell, first netted filtration and second netted filtration 53, seal shell has seted up inlet 5111, first netted filtration installs in inlet 5111, in order to filter the sewage that gets into inlet 5111, seal shell has still seted up outlet 5151, second water pipe 4 is connected in outlet 5151, second netted filtration 53 is installed in seal shell, and second netted filtration 53 is located between inlet 5111 and outlet 5151, in order to filter the sewage that gets into outlet 5151, first netted filtration and second netted filtration are provided with a plurality of first filtration and a plurality of second filtration respectively, the aperture of first filtration is greater than the second filtration.
Through the above structure, when sewage needs to be collected, the filter head 5 is put into the sewage, the water pump 1 is started, the sewage enters the water inlet 5111 through the first net-shaped filter structure, the first net-shaped filter structure filters the sewage entering the water inlet 5111, the filtered water enters the inside of the closed shell, and then is filtered again through the second net-shaped filter structure 53, the filtered water enters the water outlet 5151 again, and then enters the second water pipe 4 again, and finally is injected into the sewage collecting container 2. The first mesh filter structure has a first pore size larger than the second mesh filter structure 53, so that the first mesh filter structure filters out large-sized floats and most of large-sized long-sized floats in the sewage at the water inlet 5111, the sewage entering the closed shell contains small-sized floats and small-sized long-sized floats, the second mesh filter structure 53 with smaller pores can filter out small-sized floats and small-sized long-sized floats, and thus the sewage finally entering the sewage collecting container 2 is purer (i.e. the content of solid-state floats is lower), and the sampling assembly filters out large-sized floats and small-sized floats by means of the first mesh filter structure and the second mesh filter structure 53 respectively, so that the probability that the first mesh filter structure and the second mesh filter structure 53 are blocked is lower.
Optionally, the enclosure in this embodiment includes a stepped tube, a first sealing plate 514, and a second sealing plate 515, where:
the stepped pipe is composed of a first pipe 511, a conical pipe 512 and a second pipe 513 which are coaxially arranged and integrally formed, and the pipe diameter of the first pipe 511 is larger than that of the second pipe 513. A first sealing plate 514 is bonded to the free end of the first tube 511 (i.e., the end of the first tube 511 facing away from the second tube 513) to seal the free end of the first tube 511. A second sealing plate 515 is welded or glued or hot-melt-bonded to the free ends of the second tubes 513 (i.e. the ends of the second tubes 513 facing away from the first tubes 511) to close the free ends of the second tubes 513.
The water inlet 5111 is formed on the wall of the first pipe 511, the second mesh filter 53 is installed in the second pipe 513, and the water outlet 5151 is formed on the second sealing plate 515. Thus, the sewage passes through the first pipe 511 of the water inlet 5111 and then passes through the tapered pipe 512, and then enters the second pipe 513, and the tapered pipe 512 is arranged to enable the sewage to flow more smoothly in the closed shell.
Preferably, the outer wall of the free end of the first pipe 511 may be further provided with a weight, so that the filter head 5 can be smoothly submerged in the sewage after the filter head 5 provided in the present embodiment is put into the water, and the free end of the first pipe 511 is maintained to face downward.
An alternative implementation of this embodiment is as follows: the second mesh-shaped filter structure 53 includes a conical screen 531, a mounting ring 532, and a third seal plate 533, wherein:
the conical screen 531 has a conical top end and a conical bottom end, and the mesh of the conical screen 531 forms the second filter holes. The mounting ring 532 is integrally formed at the tapered bottom end of the tapered mesh plate 531, the mounting ring 532 is coaxial with the tapered mesh plate 531, and the third sealing plate 533 is integrally formed at the tapered bottom end of the tapered mesh plate 531. When installed, the installation ring 532 is screwed to the second pipe 513, and the tapered bottom end of the tapered mesh plate 531 faces the second sealing plate 515.
Thus, the sewage entering the second pipe 513 passes through the mounting ring 532 and then enters the inner area of the conical screen 531, the sewage passes through the meshes of the conical screen 531 and then enters the water outlet 5151, and the small-sized floats in the sewage are collected in the inner area of the conical screen 531 and blocked by the third sealing plate 533 under the impact of the sewage, and the small-sized floats in the conical screen 531 are jumped under the impact of the sewage, so that the probability that the small-sized floats block the meshes of the conical screen 531 is further reduced.
More preferably, a reinforcing rib plate 534 is further connected to the inner circumferential wall of the mounting ring 532, and the reinforcing rib plate 534 is given a cross shape in outline. By means of the reinforcing rib plate 534, the structural strength of the entire mounting ring 532 and thus the structural strength of the entire second mesh filter structure 53 can be further enhanced.
Preferably, a rotating shaft 535 is rotatably installed between the reinforcing rib 534 and the third sealing plate 533, specifically, the reinforcing rib 534 and the third sealing plate 533 are provided with coaxial round holes, and two ends of the rotating shaft 535 are respectively rotatably inserted into the round holes on the reinforcing rib 534 and the round holes on the third sealing plate 533. A plurality of blades 536 are uniformly distributed on the rotating shaft 535, and the blades 536 are rotatably disposed between the reinforcing rib plate 534 and the third sealing plate 533, that is, the blades 536 are rotatably disposed inside the conical screen 531.
When sewage is pumped by the water pump 1 and flows towards the water outlet 5151, the sewage will apply a force to the blades 536, and the blades 536 have an included angle of 15-30 ° relative to the sewage flowing direction, so that the flowing sewage will rotate the blades 536, and the rotating blades 536 can cut or crash part of the small-particle-size floaters inside the conical screen 531, so that the particle size of the small-particle-size floaters is further reduced or dissolved, further avoiding the blockage of the meshes of the conical screen 531, and in addition, the rotating blades 536 can wind the long-shaped floaters, further avoiding the blockage of the meshes of the conical screen 531.
When the second mesh filter structure 53 is to be replaced or cleaned, it is only necessary to screw it out of the second tube 513, and of course, the first sealing plate 514 is to be removed when the second mesh filter structure 53 is to be removed.
An alternative implementation of this embodiment is as follows: the first mesh filter structure is a mesh tube 52, the mesh holes of the mesh tube 52 form the first filter holes, the mesh tube 52 is screwed to the water inlet 5111, and one end of the mesh tube 52 facing away from the first tube 511 is plugged by a fourth sealing plate 521. Moreover, the number of the water inlets 5111 on the first pipe 511 is plural, and the water inlets 5111 are uniformly distributed along the circumference of the first pipe 511, and each water inlet 5111 is provided with one of the net pipes 52. Thus, the sewage can pass through the mesh openings of the mesh tube 52 to enter the interior of the mesh tube 52 and then enter the water inlet 5111. The plurality of net pipes 52 are distributed on the pipe wall of the first pipe 511 in a divergent manner along the circumferential direction of the first pipe 511, so that the probability of blocking all the net pipes 52 is lower.
The above description is merely an embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art can easily think about changes or substitutions within the technical scope of the present utility model, and it is intended to cover the scope of the present utility model.
