[0001] The invention belongs to the field of water treatment equipment, and in particular relates to a floating island type water sampling head. Background Art

[0002] In the process of water treatment, the sedimentation tank is the most cost-effective and effective treatment process. In the sedimentation tank, the water flows and settles during the movement, and the clean water is extracted and discharged for subsequent treatment. However, the water intake method of the sedimentation tank is relatively simple. Most of them are to set up water intake holes at the end to directly take water. This water intake method causes the water flow to obviously converge at the water intake when it flows to the water intake, and the water flow will also rebound after contacting the wall. Both phenomena lead to turbulence in the process of water intake in the sedimentation tank, causing impurities to float.

[0003] The present application aims to propose a floating island water collection head to solve the above problems. Summary of the invention

[0030] Embodiment 1:

[0031] As Figure 1-8 shown, a floating island type water intake head includes an outer shell 401, a floating block 410 is fixedly arranged inside the outer shell 401, a water intake member is arranged on the floating block 410, the water intake member is connected with a pull rope 406, the pull rope 406 is connected with a counterweight member, and pulling the water intake member by the pull rope 406 can change the water intake area of the water intake member.

[0032] Furthermore, two adjacent plug-ins 403 are provided on the shell 401 , and two adjacent slots 402 are opened on the shell 401 , and the shells 401 of two floating island water collection heads can be connected through the plug-ins 403 and the slots 402 .

[0033] Furthermore, the counterweight comprises a base cover 407 , which is provided with a plurality of openings, a counterweight block 409 is slidably arranged inside the base cover 407 , and a pull rope 406 slides through the base cover 407 and is fixedly connected to the counterweight block 409 .

[0034] Furthermore, the water intake member includes a first sliding seat 404, the first sliding seat 404 is fixedly connected to the floating block 410, a first water intake housing 405 is slidably arranged in the first sliding seat 404, the lower end of the first water intake housing 405 is fixedly connected to the pull rope 406, a plurality of water intake holes are evenly arranged on the side of the first water intake housing 405, and a first water outlet 408 is arranged on the upper side of the first sliding seat 404. The density of the first water intake housing 405 is less than the density of water.

[0035] The floating island water collecting head in the present application is mainly used in the process of taking water from the sedimentation tank 1. A water supply inlet 2 is provided on one side of the sedimentation tank 1, and a water supply outlet 3 is provided on the other side. A floating island water collecting head group 4 is provided in the sedimentation tank 1. The floating island water collecting head group 4 is formed by splicing a plurality of floating island water collecting heads. A plurality of mud discharge ports 5 may also be provided at the bottom of the sedimentation tank 1. During specific installation, the base cover 407 is covered on the upper end of the mud discharge port 5 so that the counterweight 409 blocks the mud discharge port 5. A mud discharge channel 6 is provided at the outer end of the mud discharge port 5 in the same row at the bottom of the sedimentation tank 1. A mud outlet 7 connected to a pump is provided at the bottom of the mud discharge channel 6. The mud discharge port 5 at the bottom of the sedimentation tank 1 is more than the number of floating island water collecting heads that need to be provided to ensure mud discharge during active cleaning.

[0036] Specifically, the water supply outlet 3 can be connected to the first water outlet 408 of each floating island water sampling head through a hose with multiple connection ports.

[0037] During specific operation, water flows from the water supply inlet 2 into the sedimentation tank 1. In the process of flowing from the water supply inlet 2 to the water supply outlet 3, impurities in the water gradually settle. When taking water, water flows from the water intake hole on the first water intake shell 405 into the first sliding seat 404 and the first water intake shell 405, and then enters the hose from the first water outlet 408 to the water supply outlet 3 before entering the next stage of processing. In this process, the water intake position is located above the rear side of the sedimentation, while the water intake position of the non-traditional water intake equipment is set at the end, so that water can be taken through a larger water intake area, thereby reducing the phenomenon of turbulence caused by backwash after the water flows to the end, and preventing the impurities settled at the bottom from being re-stirred up under turbulence, causing the water to become turbid.

[0038] When the water level rises, the corresponding shell 401 is driven to slide upward by the float 410, thereby increasing the water outflow rate. The number of water intake holes corresponding to the first water intake shell 405 exposed from the first sliding seat 404 increases, thereby increasing the water intake area, thereby maintaining the water flow at each water intake hole and avoiding the problem of turbulence caused by accelerated water flow when the water level rises and the water intake amount increases.

[0039] When the water level rises at a relatively fast rate, the sludge at the bottom of the sedimentation tank 1 may be too thick. In this case, when the first water intake housing 405 slides out to the maximum extent in the first sliding seat 404, the water level continues to rise, and the draft of the floating block 410 increases, the buoyancy increases, and the counterweight block 409 is pulled up by the pull rope 406 to open the mud outlet 5. At this time, the pump connected to the mud outlet 7 works to pump out the sludge. In this process, a detector can also be set at the mud outlet to detect the passing components to determine when the sludge is completely discharged and the pumping work is stopped.

[0040] When actively discharging mud, the pump is turned on to extract mud through the unblocked mud outlet 5. When the mud outlet 5 is arranged less, the bottom can be scraped by a scraper to assist in discharging mud.

[0041] Embodiment 2:

[0042] Combined with Figure 9-13 On the basis of the first embodiment, the specific configuration of the water intake member is changed: the water intake member includes a second sliding seat 412, a plurality of water intake holes are evenly arranged on the bottom surface of the second sliding seat 412, the second sliding seat 412 is symmetrically provided with sliding holes 421 on two side surfaces along the length direction of the shell 401, a second water intake shell 411 is slidably arranged in each sliding hole 421, a plurality of water intake holes are evenly arranged on the bottom surface of the second water intake shell 411, a second water outlet 414 is arranged on the side wall of the second sliding seat 412, and two sliding holes are arranged on the inner wall of the second sliding seat 412 Groove 415, a slider 419 is slidably set in the two slide grooves 415, a plurality of springs 420 are connected between the slider 419 and the top of the second sliding seat 412, two first connecting ears 418 are symmetrically set on the side of the slider 419 facing each second water intake shell 411, and two second connecting ears 416 are set at the opening of each second water intake shell 411. The first connecting ears 418 and the second connecting ears 416 at the corresponding positions are rotatably connected by a connecting rod 417, and the pull rope 406 slides through the second water intake shell 411 and is fixedly connected to the slider 419.

[0043] Furthermore, the second sliding seat 412 is rotatably connected to the floating block 410 via a hinge seat 413 .

[0044] In order to further improve the water intake and avoid the disturbance of the water flow along the water flow direction in the sedimentation tank, in this embodiment, the increase of water intake holes is achieved by horizontally sliding two second water intake shells 411 on the second sliding seat 412.

[0045] During specific operation, when the water level rises, the float block 410 drives the shell 401 to float up, thereby pulling the slider 419 downward, so that the two second water intake shells 411 are pushed out respectively through the connecting rods 417 on both sides, thereby increasing the water intake area of ​​the second water intake shell 411 and the second sliding seat 412 to cope with the increase in water intake.

[0046] When the water flow rate is too fast and the shell 401 is impacted by the water flow and deviates from the vertical position, the slider 419 can also be pulled down to push out the two second water intake shells 411. At the same time, due to the hinged arrangement of the second sliding seat 412 and the floating block 410, the water intake holes at the bottom of the second water intake shells 411 and the second sliding seat 412 can be tilted toward the direction of the water flow, which not only caters to the direction of the water flow but also conforms to the parabolic sedimentation curve of impurities in the water. In this way, water intake can avoid impurities in the water flow from being sucked into the water intake holes to the greatest extent without excessively disturbing the water flow.

[0047] The sludge discharge process is the same as that in the first embodiment, and this embodiment will not describe this part of the work in detail.

[0048] The above is only a preferred implementation of the present application. Although the present application has been disclosed as a preferred embodiment, it is not intended to limit the present application. Any technician familiar with the art can use the above disclosed methods and technical contents to make many possible changes and modifications to the technical solution of the present application without departing from the scope of the technical solution of the present application, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application still falls within the scope of protection of the technical solution of the present application.
