Description

Technical Field

[0001] The utility model belongs to the technical field of dredging devices, and particularly relates to a dredging device for high-salt sewage treatment. Background Art

[0002] With the continuous development of industrial production, the water treatment process for sewage treatment is also constantly improving. In the process of treating high-salt wastewater, generally, multiple pools with different functions are used to hold the wastewater during the treatment process. In the biological treatment process of wastewater containing calcium chloride, the water flow stays in the pool for a long time, and long-aged sludge will form at the bottom of the pool. This sludge precipitated after biological treatment contains a lot of calcium salts, and it is not easy to dehydrate even if not used. Therefore, the separation of this kind of sludge deposited at the bottom of the pool from the liquid in the pool is relatively good. When cleaning only the sludge deposited at the bottom of the pool without affecting the normal use of the pool, the traditional manual dredging efficiency is low.

[0003] A dredging device for high-salt sewage treatment is disclosed in the prior art, with the publication number: CN217811281U. When cleaning the sludge at the bottom of the pool, it is necessary to pump out all the water in the pool, and then use a stirrer to break up the exposed sludge into slurry and pump it out by a sludge pump. This traditional way of cleaning the sludge at the bottom of the pool makes the pool unable to be used, which not only affects the normal production and use of the pool, but also has low dredging efficiency, easy splashing of the sludge, and large energy consumption for the dredging work. Content of the Utility Model

[0029] Combined with the attached Figures 1 to 6 As shown, a dredging device for treating high-salt sewage includes: a gantry hanger 1, a driving beam 3, a rotary driving frame 4, a multi-axis hinge 5, a conical piercing head 6, and a draining basket 7. In the following, the partial structures and principles of the above components of the present dredging device will be specifically described.

[0030] As an example, such as Figure 1 、 Figure 2As shown in the figure, a gantry crane 1 can be arranged above the pool 2. The gantry crane 1 can be a small gantry crane with a rail-mounted mobile type. Inside the gantry crane 1, retaining plate grooves 11 are symmetrically arranged. The retaining plate grooves 11 are in the shape of U-shaped sliding grooves. A driving beam 3 that is slidably engaged with the retaining plate grooves 11 is arranged inside the retaining plate grooves 11. The driving beam 3 is connected to the hook 12 inside the gantry crane 1 in a hooked manner. The crane of the small gantry crane can pull the driving beam 3 to move in the up and down directions along the retaining plate grooves 11 through the hook 12. Lower guard beams 31 are arranged on both sides of the driving beam 3. The lower guard beams 31 are welded to the driving beam 3. The lower guard beams 31 are arranged inside the retaining plate grooves 11 for sliding engagement, ensuring that the driving beam 3 can slide smoothly inside the retaining plate grooves 11 and preventing the phenomenon of derailing. A central shaft 32 is arranged at the center of the driving beam 3. The root of the central shaft 32 has a thicker diameter in a transition shape for facilitating the bolted fixed connection with the driving beam 3. Drivers 33 are arranged on the driving beam 3 on both sides of the central shaft 32. The drivers 33 can adopt stepping motors or servo motors. The number of rotary drive frames 4 is two. The two rotary drive frames 4 are rotatably connected in a hinged manner through a multi-axis hinge 5. The multi-axis hinge 5 includes a left rotary page 51, a right rotary page 52, and a rotating shaft 53. The left rotary page 51 is rotatably connected to one side of the rotary drive frame 4, and the right rotary page 52 is rotatably connected to the other side of the rotary drive frame 4. Moreover, the left rotary page 51 and the right rotary page 52 can also be rotatably connected through the rotating shaft 53. A plurality of the multi-axis hinges 5 can be distributed between the two rotary drive frames 4. The rotating shafts 53 of the plurality of multi-axis hinges 5 can be distributed in a coaxial manner with the same axis. The rotating shaft 53 can also be coaxial with the axis of the central shaft 32. The rotating shaft 53 of the uppermost multi-axis hinge 5 between the two rotary drive frames 4 can be fixedly connected or integrally formed with the central shaft 32, ensuring that both of the two rotary drive frames 4 can rotate around the central shaft 32. Conical piercing heads 6 can be respectively arranged at the lower ends of the two rotary drive frames 4. The conical piercing heads 6 can be in the shape of a square opening. The conical piercing heads 6 are fixedly connected to the lower ends of the rotary drive frames 4 by welding. The conical piercing heads 6 can be used in a stabbing manner. Mesh bags 61 are arranged at the rear parts of the conical piercing heads 6. The mesh bags 61 can be in the shape of bottomless cylinders. The rear parts of the two conical piercing heads 6 can be tied tightly to both ends of the mesh bags 61 to form a connected state.

[0031] Refer to Figure 1As shown, the two conical piercing heads 6 are placed back to back and closely together in a V shape. The mesh bag 61 between the two conical piercing heads 6 can be folded and retracted. The lifting hook 12 drives the driving beam 3, the rotary driving frame 4, and the conical piercing heads 6 to be lowered, so that the two back-to-back conical piercing heads 6 can pass through the liquid surface 21 of the pool 2 and smoothly insert into the bottom sludge 22 of the pool; the driving beam 3 and the lower protection beam 31 are slidably matched in the baffle slot 11 to ensure that the two conical piercing heads 6 can smoothly insert into the bottom sludge 22 of the pool.

[0032] Refer to Figure 1 and Figure 2 As shown, the rotary driving frame 4 can rotate around the central axis 32. The rotary driving frame 4 can also be provided with a driving lever 41 and an annular pulley 42. The driving lever 41 can be a square rod and is welded to the upper end of the rotary driving frame 4. The annular pulley 42 can be in the shape of an annular belt pulley. The driving lever 41 can be welded to the end face of the annular pulley 42. The axis line of the annular pulley 42 and the central axis 32 are coaxially distributed. The driver 33 can drive the annular pulley 42 to rotate through belt drive. The rotation of the annular pulley 42 can synchronously drive the rotary driving frame 4 to rotate around the central axis 32 through the driving lever 41. The belt between the driver 33 and the annular pulley 42 can be tensioned by a belt tensioning pulley 43 to prevent the belt from slipping and ensure the smooth progress of the belt drive to drive the rotation of the rotary driving frame 4; when the rotary driving frame 4 rotates, it synchronously drives the conical piercing heads 6 below to move, and pierces the bottom sludge 22 into the mesh bag 61. The driving methods of the two rotary driving frames 4 are the same. When the two rotary driving frames 4 drive the conical piercing heads 6 below them to shovel into the sludge, a protective wheel 62 can be provided at the lower end of the conical piercing head 6. The protective wheel 62 can be a roller made of polytetrafluoroethylene material with good wear resistance, ensuring that the conical piercing head 6 will not produce harsh noises during the shoveling and piercing operation at the bottom of the pool, and the conical piercing head 6 will not scratch the bottom ground through the roller-shaped protective wheel 62, and at the same time effectively ensuring that the conical piercing head 6 can shovel the mud more smoothly.

[0033] Embodiment 1

[0034] As an example, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, Figure 3 is Figure 1The posture of mud stabbing when the rotary drive frame 4 and the cone stabbing head 6 rotate 90 degrees around the central axis 32. The two rotary drive frames 4 drive the cone stabbing heads 6 below them to rotate 90 degrees respectively, that is, the two rotary drive frames 4 rotate a total of 180 degrees. During the rotation of the two rotary drive frames 4, the sludge or sludge at the bottom of the pool is stabbed into the mesh bag 61 through the cone stabbing head 6. The rotary drive frame 4 can be in a C shape, which can not only increase the overall structural strength, but also can be manually or with the help of tools such as levers to be turned without belt drive through the C-shaped rotary drive frame 4, so as to realize the mud shoveling operation of the cone stabbing head 6 below at the bottom of the pool.

[0035] Refer to Figure 4 As shown, when the two side drivers 33 drive the two rotary drive frames 4 to rotate respectively, the annular pulleys 42 connected to the respective driving rods 41 on the two rotary drive frames 4 are distributed coaxially, and the inner holes of the two annular pulleys 42 are both larger than the outer diameter of the root of the central axis 32. And, for the two annular pulleys 42 distributed vertically, the outer diameters of the two annular pulleys 42 are different, and the inner hole diameter of the upper annular pulley 42 is larger than the maximum outer circle diameter of the lower annular pulley 42; that is, the outer diameter of the lower annular pulley 42 is smaller than the minimum inner hole diameter of the upper annular pulley 42. Ensure that the two annular pulleys 42 can drive their respective rotary drive frames 4 to rotate around the central axis 32 respectively.

[0037] Refer to the attached Figure 5 As shown, Figure 5 For Figure 1 the state when the two cone stabbing heads 6 of

[0038] Embodiment 3

[0039] Refer to the attached Figure 1 and Figure 6As shown in the figure, a draining basket 7 is hung at the upper end of one side wall of the pool 2. The draining basket 7 is in the shape of a basket welded by steel bars. After the net woven bag 61 filled with sludge is placed in the draining basket 7, the ropes tied at both ends of the net woven bag 61 are untied and separated from the two cone poking heads 6 respectively, and then the two ends of the net woven bag 61 are tied tightly with thin ropes to prevent the sludge from flowing out of the bag mouth of the net woven bag 61. A liquid pressing block 71 can also be arranged in the draining basket 7. The liquid pressing block 71 is a cement block or a metal block. The liquid pressing block 71 can be placed on the upper top end of the net woven bag 61 tied by all the thin ropes in the draining basket 7 through the hook 12 of the crane of the gantry hanger 1, so as to squeeze the water contained in the sludge in the net woven bag 61 by gravity, and ensure that the sludge after draining can be retained in the net woven bag 61. The structure of this device is simple. The sludge deposited at the bottom of the pool can be directly taken out without removing the water liquid in the pool. The cleaning efficiency of the sludge is high. During the process of taking out the sludge, the sludge splashes less. The cleanliness around the pool 2 is better when cleaning the sludge. Moreover, the water content in the sludge taken out through the net woven bag 61 is less, which is easy to handle or transport.

[0040] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present utility model should be based on the protection scope of the claims.
