[0036] Figure 1 This is a schematic diagram of the overall structure of the present invention. Detailed Implementation

[0037] The present invention will now be further described with reference to the accompanying drawings:

[0038] like Figure 1 As shown in Example 1, an in-situ sludge treatment device includes:

[0039] The cylinder is a sealed container with multiple mud and water inlets 51 on its side wall, and the cylinder can be suspended in sewage.

[0040] Mixing pipe 2, multiple pipes are provided, the upper end of which is fixed to the bottom of the cylinder and connected to the cylinder, and the lower end of mixing pipe 2 is aligned with the sediment in the sewage.

[0041] The motor 1 has its housing fixed inside the cylinder. The motor 1 has a water flow blade 11 fixed on its shaft. When the water flow blade 11 rotates, it can draw in mud and water from the mud and water inlet 51 and spray it out from the lower end of the mixing pipe 2 to impact the sediment in the sewage.

[0042] A gas pipe is fixed to the cylinder, the outlet of the gas pipe is located at the bottom of the cylinder, the gas outputted from the outlet of the gas pipe can mix with the sludge water in the cylinder, and the inlet of the gas pipe is communicated with the gas generator.

[0043] Preferably, the gas generator is a gas pump, which has large gas output and low cost.

[0044] Preferably, the gas generator is an ozone generator, which is more expensive but has good sterilization effect.

[0045] In order to improve the stirring effect, the rotating shaft of the motor 1 extends from the bottom of the cylinder, and the bottom of the rotating shaft is fixed with a stirring blade 12, which can stir the sludge deposited in the sewage. Some sludge has strong viscosity, and the stirring blade 12 can break and loosen the sludge.

[0046] In order to provide support for the treatment device, the bottom of the cylinder is fixed with a support frame 3, and the bottom of the support frame 3 is provided with a support plane, which can be placed in the sludge support cylinder.

[0047] In order to enable the sludge to fully contact with air or ozone, in embodiment 2, the cylinder is composed of an upper cylinder 6 and a lower cylinder 5, the diameter of the upper cylinder 6 is larger than that of the lower cylinder 5, a sludge water outlet hole 61 is formed in the side wall of the upper cylinder 6, and a sludge water inlet hole 51 is located in the lower cylinder 5, and the sludge water outlet hole 61 can spray mixed sludge water.

[0048] It should be noted that the volume of the upper cylinder 6 is relatively large, and the contact time of the sludge with air or ozone is relatively long, and the oxidation effect is relatively good.

[0049] It should be noted that when the sludge outlet amount of the plurality of mixing pipes 2 is small, part of the sludge water will flow from the lower cylinder 5 to the upper cylinder 6, and finally flow out from the sludge water outlet hole 61, and part of the mixing pipes 2 can be closed to increase the output of the sludge water outlet hole 61.

[0050] Preferably, the upper cylinder 6 is a conical body, the top of the conical body is provided with a cover 7, and part of the mixing pipes 2 are connected with valves, and part of the valves can be closed according to needs. It should be noted that due to the difference in density of the sludge, sometimes it is necessary to increase the impact force, but the power of the motor is constant, at this time, part of the valves can be closed to concentrate the energy and increase the impact force of the water.

[0051] Preferably, on the basis of the above embodiment, the cylinder is hung on at least one small boat 8, and two small boats are selected in this embodiment, which are symmetrically arranged, and the cylinder position detection device is also installed on the small boat 8, which comprises:

[0052] A winding drum 98 is rotatably fixed on the small boat 8;

[0053] A cable motor 99 is fixed to the small boat 8, the rotating shaft of the cable motor 99 is fixed to the rotating shaft of the reel 98, the cable motor 99 can drive the reel 98 to rotate, the cable motor 99 is electrically connected to the controller, and the controller is installed on the small boat 8;

[0054] A position detecting sleeve 92 is fixed to the top of the cylinder;

[0055] A sling 91 is wound on the reel 98 at the upper end, the sling 91 passes through the top hole of the position detecting sleeve 92, and the lower end of the sling 91 is fixed with a movable block 94 in the position detecting sleeve 92;

[0056] A compression spring 93 is sleeved on the sling 91 and located between the movable block 94 and the top surface of the position detecting sleeve 92;

[0057] A magnetic block 95 is fixed below the movable block 94;

[0058] A Hall sensor 97 is fixed to the bottom of the position detecting sleeve 92, the Hall sensor 97 can collect the position signal of the magnetic block 95, the Hall sensor 97 is electrically connected to the controller, and the Hall sensor 97 can be waterproof treated;

[0059] A limiting block 96 is fixed to the inner wall of the position detecting sleeve 92, and the limiting block 96 can control the movable block 94 to move within a certain range upward and downward;

[0060] When the cylinder is away from the bottom mud, the controller can control the cable motor 99 to rotate to move the cylinder to approach the bottom mud through the signal collected by the Hall sensor 97.

[0061] It is to be noted that one of the purposes of the present application is to turn the bottom mud up, when the cylinder is away from the bottom mud, the buoyancy generated by the discharge capacity of the motor 1 is different, generally, the buoyancy increases when the cylinder approaches the bottom mud, and the buoyancy can be reflected through the Hall sensor 97.

[0062] The cylinder position detecting device is provided with two sets, the cable motor 99 is connected to the reel 98 through a speed reducer, the two sets of cylinder position detecting devices can detect whether the cylinder position detecting device is horizontally arranged, and the controller can prompt manual processing when necessary, and the speed reducer is arranged to improve the control accuracy.

[0066] S3. The value between the upper limit output and the lower limit output is taken as the standard value;

[0067] S4. When the sludge bottom in-situ treatment device starts formal work, the cable motor 99 does not act as long as the standard value is reached, and the cable motor 99 acts if the standard value is not reached, adjusting the height position of the sludge bottom in-situ treatment device until the standard value is reached.

[0068] It should be noted that since the bottom is loose and tight, the bottom of each pond and river is different, and the best bottom treatment position is obtained through pre-calibration, which can greatly improve the treatment effect and adapt to different water bottom environment.
