Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and more specifically, to a sludge treatment device for water conservancy projects. Background Technology

[0002] Silt treatment devices for water conservancy projects are key equipment used to treat the large amounts of silt generated during the dredging of rivers, lakes, reservoirs and other water bodies. With China's increasing emphasis on water environment management, flood control and drainage capacity improvement and sustainable water resource utilization, river dredging is widely used as an important measure to restore water function and ensure flood control safety. In this process, silt with complex composition, high water content and huge volume is generated. Traditional methods such as simple natural drying or direct off-site transportation and stockpiling not only occupy a lot of land and take a long time, but may also cause secondary pollution. Therefore, efficient mechanized silt treatment devices have emerged.

[0003] The cutter suction dredging device works by rotating the cutter head at the end to cut and agitate underwater silt, and using the negative pressure generated by the pump to transport the silt-water mixture to a designated location through the dredging pipe. However, fibrous debris such as aquatic plants, fishing nets, and plastics are easily entangled on the rotating parts outside the cutter head, leading to a decrease in equipment efficiency. In addition, traditional cutter heads often have difficulty effectively cutting and breaking up long-term hardened and highly viscous bottom silt, easily forming suction cavities or only being able to remove the loose surface layer, failing to thoroughly dredge the silt. Furthermore, directly suctioning such solid blocks can easily cause blockages at the inlet or inside of the dredging pipe. Therefore, we propose a silt treatment device for water conservancy projects. Summary of the Invention

[0010] Preferably, the elastic element includes a pressing seat disposed on the outside of the transmission shaft, one end of the pressing seat abutting against the outer wall of the spiral shaft, and a compression spring disposed on one end of the pressing seat, the compression spring abutting against the inner wall of the sludge removal chamber.

[0011] Preferably, the driving component includes a second motor disposed in the slot, a rotating rod disposed at the rotor shaft end of the second motor, a second gear disposed on the outer wall of the rotating rod, a circular plate disposed in the slot, a second gear ring disposed on the outer wall of the circular plate, and the second gear meshing with the second gear ring.

[0012] Preferably, the annular component includes a protrusion at the bottom end of the circular plate, the protrusion having a central hole, and the outer wall of the protrusion having multiple sets of arc-shaped grooves, the central hole being connected to the inner side of the sludge removal pipe.

[0013] Preferably, the adjusting component includes two sets of anti-blocking covers, namely, anti-blocking cover one and anti-blocking cover two, which cooperate with each other to form an anti-blocking part. The diameter of one set of anti-blocking parts is larger than that of the other set. It also includes an anti-blocking platform, in which the anti-blocking part is locked. The bottom end of the anti-blocking platform is provided with a circumferential groove. The inner side of anti-blocking cover one is provided with a locking part one, and a positioning strip one is provided on one side wall of the locking part.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, the rotating ring drives the shredding strips to rotate, thereby cleaning the debris on the outside of the suction head. Since the middle part of the multiple sets of cleaning strips forms a connecting seat, the bottom end of the connecting seat is slidably connected to the deflection groove through the limiting block on the outside of the auxiliary rod, thereby driving the cleaning strips to move in the axial direction. Since simple rotation may only make the tangled material more tightly wrapped, the combined horizontal movement can produce an axial combing or pushing effect, realizing active defense without dead angles and ensuring the continuity of operation.

[0016] 2. In this invention, the anti-winding mechanism cuts and breaks up the silt that has hardened on the riverbed and mixes it thoroughly with the surrounding water to form a homogeneous mud-water mixture with significant fluidity. In this process, the anti-blocking mechanism keeps the dredging pipe closed and pumps it in after the silt has been fully fluidized, thus avoiding overload caused by directly pumping high-viscosity solids.

[0017] 3. In this invention, the drive shaft is driven to rotate by an adaptive mechanism, and the drive shaft is connected to the squeezing seat by a compression spring. At this time, the squeezing seat and the compression spring are in a state of force balance. When the fluid density changes, the spiral shaft converts the increased torque into a strong thrust in the axial direction, forcing the compression spring to push the squeezing seat against the spiral shaft, reducing its pitch. Thus, at the same rotation speed, the spiral shaft can be driven to generate higher thrust by sacrificing the sewage flow rate, thereby discharging the high-viscosity sewage.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example 1

[0023] The present invention provides a sludge treatment device for water conservancy projects, which includes a sludge removal pipe 100. A suction head 101 is seamlessly welded to the end of the sludge removal pipe 100. A groove 102 is formed inside the suction head 101. The middle position of the groove 102 is connected to the sludge removal pipe 100. An annular ring 103 is rotatably connected to the outside of the suction head 101. A crushing strip 104 is circumferentially fixedly connected to the outer wall of the annular ring 103. A fixing seat 105 is fixedly connected to the middle area of ​​multiple sets of crushing strips 104. Depend on Figure 1 It is known that its sludge cleaning pipe 100 is connected to the inlet of the external sludge treatment device through a flange. When the suction head 101 is working, large pieces of hard mud or encased garbage, such as stones or woven bags, may directly enter the suction port and get stuck at the pipe bend or diameter change. The device has an annular ring 103 rotatably connected to the outside of the suction head 101. Multiple sets of crushing strips 104 are fixed in a circular shape on the outside of the annular ring 103. An anti-winding mechanism 200 is provided. The anti-winding mechanism 200 includes a movable part 201 set in the fixed seat 105. A support part 202 is provided on the outside of the suction head 101. A deflector 203 is provided in the support part 202. The movable part 201 and the deflector 203 cooperate to continuously clean the outer wall of the suction head 101. Furthermore, this device utilizes the combined movement of the shredder 104 and the cleaning bar 203a. The design feature is that when the shredder 104 rotates, it drives the cleaning bar 203a to move axially. Simple rotation may only make the tangled material more tightly wrapped, while the combined horizontal movement can generate an axial combing or pushing effect. Once debris begins to entangle, this horizontal movement is like a human finger, pulling it off the axis, achieving active defense without blind spots. If the sludge inside the dredging pipe 100 has a high viscosity concentration, this device can adapt by setting an adaptive mechanism 300 inside the dredging pipe 100. The adaptive mechanism 300 includes a transmission component 301 set inside the dredging pipe 100 and an elastic component 302 set outside the transmission component 301. The transmission component 301 and the elastic component 302 cooperate to adapt to the viscosity of the sludge, compressing and reducing the pitch of the spiral shaft 301d, so that the device can sacrifice the sewage flow rate to obtain higher thrust to discharge the high viscosity part. Because the density and viscosity of silt are much higher than that of water, directly sucking up the hardened silt is like sucking up a cup of very thick paste with a straw. It requires a lot of power, the flow rate is slow, and the efficiency is low. This device has an anti-clogging mechanism 400 in the dredging pipe 100. The driving component 401 of the suction head 101 is set in the drive component 401, the slot 102 is set with an annular component 402, and the annular component 402 is set with an adjusting component 403. The annular component 402 and the adjusting component 403 cooperate to block the silt on the outside of the suction head 101. It can be seen that this device cuts and breaks up the hardened silt on the riverbed by driving the crushing strip 104 on the outside of the suction head 101 to rotate. Working principle: During use, the suction head 101 on the outside of the dredging pipe 100 is placed at the work site. The shredding strips 104 on the outside of the suction head 101 are then driven to rotate, cutting and breaking up the hardened silt on the riverbed and thoroughly mixing it with the surrounding water to form a highly fluid and homogeneous mud-water mixture. During this process, the dredging pipe 100 remains closed. After the silt has been fully fluidized, the dredging pipe 100 is reopened to minimize clogging. Then, the rotation of the shredding strips 104 drives the cleaning strips 203a to move axially. Simple rotation may only... The purpose is to make the entangled material tighter, while the combined horizontal movement can generate an axial combing or pushing effect. Once debris begins to entangle, this horizontal movement is like a human finger, pulling it off the shaft, achieving active defense without dead angles, eliminating potential entanglement in its infancy, reducing unplanned downtime caused by entanglement, and ensuring the continuity of operation. At the same time, this device adapts to the viscosity of sludge through the cooperation of the transmission component 301 and the elastic component 302, compressing and reducing the pitch of the spiral shaft 301d, so that the device can sacrifice the sewage flow rate to obtain higher thrust to discharge the high viscosity part. Example 2

[0024] Based on Embodiment 1, the following technical features are added: The anti-entanglement mechanism 200 includes a movable part 201, a support part 202 is provided on the outside of the suction head 101, and a deflector 203 is provided inside the support part 202. The movable part 201 and the deflector 203 cooperate to continuously clean the outer wall of the suction head 101. The movable part 201 includes a cavity 201a provided in the fixed seat 105. The inner wall of the cavity 201a is provided with a deflection groove 201b. The deflection groove 201b is composed of a high part 201c, an inclined part 201d and a low part 201e. A gear ring 201f is fixedly connected to the inner side of the annular ring 103. A motor 201g is detachably installed on the outside of the sludge removal pipe 100. A drive rod 201h is fixedly connected to the rotor shaft end of the motor 201g. A gear 201i is fixedly connected to the outer wall of the drive rod 201h. The gear ring 201f meshes with the gear 201i. Depend on Figures 1 to 3 It is known that the motor 201g is regulated by an external controller. The motor 201g drives the drive rod 201h to rotate. The drive rod 201h rotates at the same time, driving the gear 201i to rotate. Since the gear ring 201f meshes with the gear 201i, it drives the outer ring 103 to rotate synchronously. In this way, through the rotation of the ring 103, the moving part 201 and the deflecting part 203 cooperate to continuously clean the outer wall of the suction head 101, thus removing potential entanglement in its early stage and reducing unplanned downtime caused by entanglement. The support member 202 includes a support portion 202a that is circumferentially fixedly connected to the outside of the suction head 101. Multiple sets of support portions 202a are fixedly connected to the outside of annular bars 202b. A sleeve 202c is circumferentially fixedly connected to the upper end face of the annular bars 202b. The deflection member 203 includes cleaning bars 203a that are sequentially movably connected to the sleeve 202c. A connecting seat 203b is fixedly connected to the middle position of multiple sets of cleaning bars 203a. An auxiliary rod 203c is fixedly connected to the bottom end of the connecting seat 203b. A limiting block 203d is fixedly connected to the outer wall of the auxiliary rod 203c. The limiting block 203d is slidably connected to the deflection groove 201b. Depend on Figures 2 to 7It can be seen that the outer side of the suction head 101 is fixedly connected to an annular strip 202b through six sets of support parts 202a. The outer side of the annular strip 202b is circumferentially fixed with a sleeve 202c. A cylindrical groove is formed inside the sleeve 202c. A cleaning strip 203a moves vertically inside the cylindrical groove. The cleaning strip 203a is slidably connected inside the sleeve 202c. The distance that the cleaning strip 203a slides inside the sleeve 202c is part of the vertical direction of the deflection groove 201b. The cleaning strip 203a cannot slide out of the sleeve 202c. A circular connecting seat 203b is formed in the middle of the multiple sets of cleaning strips 203a. An auxiliary rod 203c is fixed at the bottom of the connecting seat 203b. The auxiliary rod 203c is slidably connected to the deflection groove 201b through a limiting block 203d. When the fixed seat 105 rotates, it drives the cleaning strip 203a on the outer side of the connecting seat 203b to move axially. Working principle: In use, the device is driven by motor 201g to rotate drive rod 201h. Simultaneously, drive rod 201h rotates gear 201i. Since gear ring 201f meshes with gear 201i, it drives the outer annular ring 103 to rotate synchronously. The rotation of annular ring 103 drives the pulverizing strip 104 to rotate, thereby cleaning debris from the outside of the suction head 101. The pulverizing strip 104 drives the fixed base 105 to rotate. The fixed base 105 has a deflection groove 201b. 01b consists of a high section 201c, an inclined section 201d, and a low section 201e. Since a connecting seat 203b is formed in the middle of multiple sets of cleaning strips 203a, the bottom end of the connecting seat 203b is slidably connected to the deflection groove 201b through the limiting block 203d on the outside of the auxiliary rod 203c, thereby driving the cleaning strips 203a to move in the axial direction. Since simple rotation may only make the entangled material more tightly wrapped, the combined horizontal movement can generate an axial combing or pushing effect, realizing active defense without dead angles and ensuring the continuity of operation. Example 3

[0025] Based on Embodiment 2, the following technical features are added: An adaptive mechanism 300 is also included. The adaptive mechanism 300 includes a transmission component 301, and an elastic component 302 is provided on the outside of the transmission component 301. The transmission component 301 and the elastic component 302 cooperate to adapt to the viscosity of the sludge. The transmission component 301 includes a drive shaft 301a fixedly connected to the bottom end of the fixed base 105. A sludge-clearing cavity 301b is formed inside the sludge-clearing pipe 100, and a sludge outlet 301c is provided at the bottom end of the sludge-clearing cavity 301b. The outer side of the drive shaft 301a... The portion located in the dredging chamber 301b includes a spiral shaft 301d. A wear-resistant strip 301e is detachably installed inside the spiral shaft 301d. The elastic element 302 includes a compression seat 302a movably connected to the outside of the transmission shaft 301a. One end of the compression seat 302a abuts against the outer wall of the spiral shaft 301d, and a compression spring 302b is fixedly connected to one end of the compression seat 302a. The compression spring 302b is a carbon spring with high strength, which is convenient for daily use. The compression spring 302b abuts against the inner wall of the dredging chamber 301b. Depend on Figures 2 to 8 It can be seen that its spiral shaft 301d is in the shape of a spiral cylindrical spring with a circular cross-section. It is made of lightweight elastic material and is used to drive sewage when rotating. The elastic force of its elastic element 302 and the spiral shaft 301d reaches a state of balance. However, the change in fluid viscosity will break this force balance. By sacrificing the sewage discharge velocity, a higher thrust is obtained to discharge the high viscosity part. Conversely, when the fluid viscosity decreases and the fluidity is higher, the pitch of the spiral shaft 301d increases to increase the sewage discharge velocity. Working Principle: This device further refines the structure of the sludge removal pipe 100. While the anti-winding mechanism 200 is in use, it drives the transmission shaft 301a to rotate. A spiral shaft 301d is installed on the outside of the transmission shaft 301a. The spiral shaft 301d is a spiral cylindrical spring with a circular cross-section, made of lightweight elastic material. During rotation, it drives the sewage. The transmission shaft 301a is connected to a compression seat 302a via a compression spring 302b. At this time, the compression seat 302a and the compression spring 302b are in a state of force balance. When the fluid viscosity changes, the spiral shaft 301d pushes the sewage... The resistance will increase significantly, which will inhibit the rotation of the screw shaft 301d. The screw shaft 301d will rotate at a slower speed, while the output speed of the motor 201g will remain relatively unchanged. Therefore, the force between the motor 201g and the screw shaft 301d will increase. Thus, the screw shaft 301d will convert the increased torque into a strong thrust in the axial direction, forcing the compression spring 302b to push the squeezing seat 302a against the screw shaft 301d, reducing its pitch. Thus, at the same speed, the screw shaft 301d can generate higher thrust by sacrificing the sewage flow rate, thereby discharging the highly viscous sewage. Example 4

The motor 401a drives the gear 401c to rotate. Since the gear 401c meshes with the gear ring 401e, the gear ring 401e rotates while driving the circular plate 401d to rotate. The circular plate 401d rotates while driving the protrusion 402a to rotate. A cylindrical central hole 402b is formed in the protrusion 402a. Adjusting component 403 includes two sets of anti-blocking covers 403a and 403b, which cooperate to form an anti-blocking part 403c. The diameter of one set of anti-blocking parts 403c is larger than that of the other set. It also includes an anti-blocking platform 403d, in which the anti-blocking part 403c is locked. The anti-blocking platform 403d is fixed to the upper surface of the slot 102 by an L-shaped structure. The bottom end of the anti-blocking platform 403d is provided with a circumferentially shaped slot 403e. A locking part 403f is fixed inside the anti-blocking cover 403a. A positioning strip 403g is fixed to the side wall of the locking part 403f. The inside of the anti-blocking cover 403a is away from the locking part 403. One end of f is fixed with a first insertion block 403h, the inner side of the second anti-blocking cover 403b is fixed with a second locking part 403i, the side wall of the second locking part 403i is fixed with a second positioning strip 403j, the inner side of the second anti-blocking cover 403b away from the second locking part 403i is fixed with a second insertion block 403k, the first locking part 403f and the second insertion block 403k cooperate with each other, the second locking part 403i cooperates with the first insertion block 403h, the first anti-blocking cover 403a and the second anti-blocking cover 403b are provided with a second slot 403l at corresponding positions, the first insertion block 403h and the second insertion block 403k cooperate with the second slot 403l, and the first positioning strip 403g and the second positioning strip 403j are slidably connected in the arc groove 402c. Depend on Figures 4 to 8It can be seen that the anti-blocking platform 403d has a semi-circular structure. The anti-blocking platform 403d is fixed to the upper end face of the slot 102 by an L-shaped structure. Therefore, the anti-blocking platform 403d is stationary. The anti-blocking part 403c is stuck inside the anti-blocking platform 403d. The anti-blocking cover 403a and the anti-blocking cover 403b together form the anti-blocking part 403c. The bottom end of the slot 102 is detachably equipped with a motor 401a. The motor 401a drives the protrusion 402a on the inner side of the circular plate 401d to rotate through a gear structure. The circular plate 401d drives the arc groove 402 on the protrusion 402a to rotate. c rotates synchronously. Due to the deflection force of the arc groove 402c, the positioning strip 403g and positioning strip 403j deflect according to the arc of the arc groove 402c, thereby driving the two sets of anti-blocking parts 403c to rotate relative to each other. As shown in the figure, the anti-blocking cover 403a and anti-blocking cover 403b rotate relative to each other, which adjusts the opening size of the anti-blocking platform 403d. When rotating clockwise, the opening size of the anti-blocking platform 403d is the largest, and its transmission shaft 301a passes through the anti-blocking platform 403d. When rotating counterclockwise, the opening of the anti-blocking platform 403d is closed. Working principle: During use, the external controller starts motor 401a, which drives gear 401c to rotate. Since gear 401c meshes with gear ring 401e, the rotation of gear ring 401e simultaneously drives the circular plate 401d to rotate. The rotation of circular plate 401d, in turn, drives the protrusion 402a to rotate. Because the outer wall of protrusion 402a has multiple sets of arc-shaped grooves 402c, and positioning strips 403g and 403j are correspondingly slidably connected within these arc-shaped grooves, the deflection force of the arc-shaped grooves 402c causes the two sets of anti-blocking parts 403c to rotate relative to each other. The anti-blocking cover 403a and... The anti-blocking cover 403b rotates relative to each other, adjusting the opening size of the anti-blocking platform 403d. When rotating clockwise, the opening size of the anti-blocking platform 403d is at its maximum, and the drive shaft 301a passes through the anti-blocking platform 403d. When rotating counterclockwise, the opening of the anti-blocking platform 403d is closed. Therefore, before use, this device cuts and breaks up the silt that has hardened on the riverbed and mixes it thoroughly with the surrounding water to form a homogeneous mud-water mixture with significant fluidity. During this process, the sludge removal pipe 100 remains closed. After the silt has been fully fluidized, it is then pumped, avoiding the risk of start-up overload, energy waste, and pipe blockage caused by directly pumping high-viscosity solids.
