[0036] Figure 1 It is a schematic diagram of the overall structure of the utility model. DETAILED DESCRIPTION

[0037] The utility model is now further described in conjunction with the accompanying drawings:

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

[0039] The cylinder is a sealed container with a plurality of mud and water inlet holes 51 opened around the side wall, and the cylinder can be suspended in the sewage;

[0040] There are multiple mixing tubes 2, the upper ends of which are fixed to the bottom of the cylinder and connected to the cylinder, and the lower ends of the mixing tubes 2 are aimed at the sediment precipitated in the sewage;

[0041] The motor 1, whose housing is fixed in the cylinder, has a water flow blade 11 fixed to the rotating shaft of the motor 1. When the water flow blade 11 rotates, muddy water can be sucked in from the muddy water inlet hole 51 and sprayed out from the lower end of the mixing pipe 2 to impact the bottom mud precipitated in the sewage;

[0042] The air pipe is fixed to the cylinder, and the outlet end of the air pipe is located at the bottom of the center of the cylinder. The gas output from the outlet end of the air pipe can be mixed with mud and water in the cylinder, and the inlet end of the air pipe is connected to the gas generator.

[0043] Preferably, the gas generator is an air pump, which has a large gas production capacity and low cost.

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

[0045] In order to improve the stirring effect, the shaft of the motor 1 extends from the bottom of the cylinder, and a stirring blade 12 is fixed to the bottom of the shaft. The stirring blade 12 can stir the sludge precipitated in the sewage. Some sludge is very sticky, and the stirring blade 12 can break and loosen the sludge.

[0046] In order to provide support for the processing device, a support frame 3 is fixed to the bottom of the cylinder, and a support plane is provided at the bottom of the support frame 3, and the support plane can be placed on the bottom mud support cylinder.

[0047] In order to allow the bottom mud to fully contact with air or ozone, in Example 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. Mud and water outlet holes 61 are opened around the side wall of the upper cylinder 6. The mud and water inlet hole 51 is located in the lower cylinder 5. The mud and water outlet holes 61 can spray out mixed mud and water.

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

[0049] It should also be noted that when the mud and water outlet volume of multiple mixing tubes 2 is relatively small, some of the mud and water will flow from the lower cylinder 5 to the upper cylinder 6 and finally flow out from the mud and water outlet hole 61. Some mixing tubes 2 can also be closed to increase the output volume of the mud and water outlet hole 61.

[0050] Preferably, the upper cylinder 6 is a cone, and a cover 7 is provided on the top of the cone. Some mixing tubes 2 are connected in series with valves, and some valves can be closed as needed. It should be noted that due to the difference in density of the bottom mud, sometimes it is necessary to increase the impact force, but because the power of the motor is constant, at this time, some valves can be closed to concentrate energy and increase the impact force of water.

[0051] As a preference, on the basis of the above embodiment, the cylinder is hoisted on at least one boat 8. In this embodiment, two boats are selected and symmetrically arranged. The boat 8 is also equipped with a cylinder position detection device, which includes:

[0052] a reel 98 rotatably fixed to the boat 8;

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

[0054] A positioning sleeve 92, which is fixed to the top of the cylinder;

[0055] A sling 91, the upper end of which is wound on a reel 98, the sling 91 passes through the top hole of a positioning sleeve 92, and a movable block 94 is fixed to the lower end of the sling 91, and the movable block 94 is located in the positioning sleeve 92;

[0056] A compression spring 93, which is mounted outside the sling 91 and is located between the movable block 94 and the top surface of the positioning sleeve 92;

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

[0058] A Hall sensor 97 is fixed at the bottom of the positioning 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. The Hall sensor 97 can be waterproof.

[0059] The limit block 96 is fixed to the inner wall of the positioning sleeve 92, and the limit block 96 can control the movable block 94 to move within a certain range up and down;

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

[0061] It should be noted that one of the purposes of the present invention is to turn up the bottom mud. When the cylinder is away from the bottom mud, the buoyancy generated by the discharge of its motor 1 is different. Usually, when it is close to the bottom mud, the buoyancy increases and can be reflected by the Hall sensor 97.

[0062] There are two sets of cylinder position detection devices. The cable motor 99 is connected to the reel 98 through a reducer. The two sets of cylinder position detection devices can detect whether the cylinder position detection devices are set horizontally. If necessary, the controller can prompt and manually handle it. The reducer is set to improve the control accuracy.

[0063] A method for treating sludge in-situ by a sludge treatment device comprises the following steps:

[0064] S1. When the sludge in-situ treatment device is at the upper limit of the predetermined position of the sludge, the motor 1 starts to work normally, and the upper limit output of the Hall sensor 97 is detected by the position of the magnetic block 95;

[0065] S2. When the sludge in-situ treatment device is at the lower limit of the predetermined position of the sludge, the motor 1 starts to work normally, and the lower limit output of the Hall sensor 97 is detected by the position of the magnetic block 95;

[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 sludge in-situ treatment device starts to work, as long as the standard value is reached, the cable motor 99 will not work. If the standard value cannot be adjusted, the cable motor 99 will work to adjust the height of the sludge bottom sludge in-situ treatment device until the standard value is reached.

[0068] It should be noted that since the bottom mud is loose or tight, the bottom mud conditions of each pond and river are different. By pre-calibrating, the best bottom mud treatment position can be obtained, which can greatly improve the treatment effect and adapt to different underwater environments.
