Description

Technical Field

[0001] This utility model relates to the field of river cleaning, and more specifically, to a river dredging and sewage suction device. Background Technology

[0002] In the field of environmental protection, river management is an important branch of environmental protection and has a crucial impact on the environment. Silt is easily deposited at the bottom of rivers. If the silt inside the river is not cleaned in time, it will emit a foul odor and seriously affect the environment. When cleaning river silt, a sewage pump is usually used to suck it up.

[0003] However, existing sewage suction pumps are generally equipped with only one filter cover on the suction head, which is used to prevent lumpy debris from entering the pipe. When the suction head is placed in sludge, it is generally relatively stationary and adsorbs, and lumpy debris tends to accumulate at its end, resulting in a decrease in adsorption efficiency. This requires frequent replacement of the adsorption point and reduces the sewage suction efficiency. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a river dredging and sewage suction device.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] The river dredging and sludge suction device includes a mobile frame, a sludge suction pump, a control box, and a sludge suction pipe. The sludge suction pump is fixedly installed on the mobile frame, and the control box is installed on the mobile frame to connect to the power supply and control the operation of the sludge suction pump. The input end of the sludge suction pump is connected to one end of the sludge suction pipe, and the output end of the sludge suction pump is connected to an external sludge storage vehicle. The other end of the sludge suction pipe is connected to an adsorption head, and the other end of the adsorption head is fixedly connected to a coarse-pore spherical cover. The adsorption head has annularly distributed blades inside.

[0007] As a further description of the above technical solution: the tip of the paddle blade extends into the channel connecting the suction head and the suction pipe.

[0008] As a further description of the above technical solution: an outer spiral plate is fixedly connected to the outside of the adsorption head, and the outer spiral plate guides the flow downward as the adsorption head rotates.

[0009] As a further description of the above technical solution: the top of the suction head is rotatably connected to a rotating joint, and the top of the rotating joint is fixedly connected to the suction pipe.

[0010] As a further description of the above technical solution: the suction pipe is a steel wire hose.

[0011] As a further description of the above technical solution: two handrails are installed on the mobile frame, and rollers with brakes are installed at the four corners of the bottom of the mobile frame.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] This design utilizes the flow of sludge to drive the paddle blades of the adsorption head, thereby increasing the adsorption duration and reducing the frequency of site replacement. Simultaneously, the adsorption head, in conjunction with the external spiral blades, pushes the wastewater floating on the surface from top to bottom, mixing it with the sludge and improving its fluidity. This achieves the advantages of dynamic adsorption, reduced interference from debris, and improved adsorption efficiency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0021] Please see Figures 1-4 In this utility model, the river dredging and sewage suction device includes a mobile frame 1, a sewage suction pump 2, a control box 4, and a sewage suction pipe 5. The sewage suction pump 2 is fixedly installed on the mobile frame 1. The control box 4 is installed on the mobile frame 1 to connect to the power supply and control the operation of the sewage suction pump 2. The input end of the sewage suction pump 2 is connected to one end of the sewage suction pipe 5. The output end of the sewage suction pump 2 is connected to an external sludge storage vehicle. The other end of the sewage suction pipe 5 is connected to an adsorption head 6. The other end of the adsorption head 6 is fixedly connected to a coarse-pore spherical cover 7. The adsorption head 6 has annularly distributed blades 8 inside.

[0022] In this invention, the movable frame 1 facilitates the movement of the suction pump 2. First, the suction pipe 5 is connected to the input end of the suction pump 2. Then, the suction head 6 at the other end of the suction pump 2 is placed into the river sludge that needs to be suctioned. The power is turned on using the control box 4, and the suction pump 2 is started to perform high-pressure suction on the sludge. As the suction pump 2 starts, the suction pipe 5 and the inside of the suction head 6 are quickly drawn into negative pressure. The suction head 6 draws the nearby sludge into the pipe. As the sludge passes through the suction head 6, it pushes the paddle blades 8 to generate thrust on the suction head 6, causing it to rotate. This drives the coarse-pore spherical cover 7 to rotate synchronously, continuously stirring the surrounding sludge and preventing blockage by lumps of debris. This achieves the advantages of dynamic suction, reducing the impact of debris and improving suction efficiency. It solves the problem in the prior art where the suction head is placed in sludge and generally adsorbs relatively statically, and lumps of debris easily accumulate at its end, leading to a decrease in suction efficiency and the need to frequently change the suction point, thus reducing suction efficiency.

[0023] Please see Figure 4 The top of the blade 8 extends into the channel connecting the suction head 6 and the suction pipe 5.

[0024] In this invention, the top of the paddle blade 8 extends into the channel connecting the adsorption head 6 and the suction pipe 5, which increases the driving force of the sludge entering the adsorption head 6 at high speed on the paddle blade 8, ensuring that the adsorption head 6 rotates continuously and ensuring the adsorption effect. At the same time, it stirs and thins the sludge, making it easier to adsorb.

[0025] Please see Figure 2 and Figure 3 The outer spiral plate 61 is fixedly connected to the outside of the adsorption head 6, and the outer spiral plate 61 guides the flow downward as the adsorption head 6 rotates.

[0026] In this invention, the outer spiral plate 61 rotates with the adsorption head 6, driving the lighter wastewater floating on the surface downwards, mixing it with the sludge, making it thinner and easier to adsorb.

[0027] Please see Figure 2 The suction head 6 is rotatably connected to a rotating joint 9, and the top of the rotating joint 9 is fixedly connected to the suction pipe 5.

[0028] In this invention, the adsorption head 6 is connected to the rotating joint 9 while simultaneously enabling it to rotate.

[0029] Please see Figure 1 Among them, the suction pipe 5 is a steel wire hose.

[0030] In this invention, the suction pipe 5 is a steel wire hose, which ensures the strength of the hose while facilitating the opening and closing of the pipe.

[0031] Please see Figure 1 Among them: two handrails 10 are installed on the mobile frame 1, and four corners at the bottom of the mobile frame 1 are equipped with braked rollers 3.

[0032] In this utility model, the handrail frame 10, together with the rollers 3, facilitates the movement of the mobile frame 1, thereby enabling the sewage pump 2 to be moved and facilitating the positioning of the mobile device.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
