Description

Technical Field

[0001] This application belongs to the field of sludge treatment technology, specifically relating to an anti-clogging automatic sludge extraction device. Background Technology

[0002] In water conveyance lines of water conservancy projects, culverts are often used to pass under obstacles such as buildings or roads. Because the longitudinal slope of culverts is usually gentle, silt is easily deposited inside, leading to blockages and affecting water conveyance efficiency. Therefore, regular dredging is necessary.

[0003] Currently, culvert dredging mainly employs a combination of a traveling trolley and a material extraction assembly. Specifically, the material extraction assembly is connected to the internal space of the traveling trolley. As the traveling trolley moves, the silt is pushed forward and accumulates. Part of the material extraction assembly extends into the silt accumulated in front to achieve continuous extraction of the silt.

[0004] The inventors discovered that during the aforementioned operation, sludge is prone to clumping and blockage, leading to blockages at the material extraction component. This blockage occurs more frequently, especially when the trolley travels at a high speed. Therefore, the speed of the trolley is set relatively slow, and the material extraction component needs to be processed periodically, making continuous operation impossible. This ultimately results in a technical defect that reduces the efficiency of sludge treatment. Utility Model Content

[0005] This application provides an anti-clogging automatic sludge extraction device, which aims to complete the extraction of sludge during the sludge pushing process and prevent sludge from clogging at the extraction point.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: A clog-resistant automatic sludge extraction device is provided, comprising: The traveling trolley is used to move within the culvert and has a storage chamber for holding silt. The collection box is located in front of the traveling trolley. It has a hollow interior and an open front, and its bottom is designed to contact the bottom surface of the culvert. The rear end of the collection box is connected to the storage chamber through a material extraction component, which is used to discharge the sludge in the collection box into the storage chamber. A feeding assembly, disposed at the opening of the collection box, is used to provide a backward force to the sludge passing through the opening of the collection box; and The crushing assembly is located inside the collection box and behind the feeding assembly. It is used to crush clumps of sludge so that the sludge can enter the storage chamber through the pumping assembly.

[0007] In one possible implementation, the feeding assembly includes: The first rotating roller is rotatably mounted at the opening of the collection box, with its axial direction and rotational direction both parallel to the horizontal plane and perpendicular to the opening direction of the collection box; and Multiple feeding plates are spaced apart along the circumference of the first rotating roller, and all are connected to the outer wall of the first rotating roller; The first roller is connected to a rotation drive component for driving its rotation; when the first roller rotates, the feeding plate can push the sludge passing through the opening of the collection box inward to enter the working range of the crushing assembly.

[0008] In one possible implementation, the shredding assembly includes: Two second rollers are spaced apart vertically within the collection box, both located behind the first roller. Each second roller is rotatably connected to the collection box, and its axial and rotational axes are parallel to the first roller. One second roller is connected to the first roller via a first synchronous transmission structure, and the two second rollers are connected via a second synchronous transmission structure, so that when the first roller rotates, the two second rollers rotate synchronously in the same direction. Two sets of crushing teeth are respectively disposed on the outer walls of the two second rotating rollers; each set of crushing teeth includes multiple crushing teeth disposed along the axial direction of the second rotating roller. A material passage gap is formed between the two second rollers to allow sludge to pass through; when the two second rollers rotate synchronously in the same direction, the two sets of crushing teeth can pass through the material passage gap in opposite directions to break up the sludge.

[0009] In one possible implementation, the first synchronous transmission structure includes: The drive wheel is coaxially connected to the first rotating roller; Driven wheel, coaxially connected to one of the second rollers; and A first synchronous belt is wrapped around the outer periphery of the drive wheel and the driven wheel to make the drive wheel and the driven wheel rotate synchronously.

[0010] In one possible implementation, the second synchronous transmission structure includes: The follower wheel is coaxially connected to another second roller; and A second synchronous belt is wrapped around the outer periphery of the driven wheel and the follower wheel so that the driven wheel and the follower wheel rotate synchronously in the same direction.

[0011] In one possible implementation, the rotation drive component includes: A rotating motor is fixedly mounted on the outside of the collection box, with its power output axis perpendicular to the axis of the first rotating roller, and a driving helical gear coaxially connected to the power output end of the rotating motor; and The driven helical gear is coaxially connected to the first rotating roller and meshes with the driving helical gear; When the rotating motor starts, the driven helical gear rotates synchronously with the driving helical gear, and drives the first rotating roller to rotate synchronously.

[0012] In one possible implementation, the material extraction component includes: A mud pump is fixedly mounted on the top of the traveling trolley, and its discharge end is connected to the storage chamber; and The feed pipe has one end connected to the feed end of the mud pump and the other end fixed to the rear end face of the collection box and connected to the inside of the collection box. The feed pipe is made of rigid material to fix the position of the collection box relative to the traveling trolley.

[0013] In one possible implementation, a baffle plate is hinged to the opening of the collection box; The hinge axis of the baffle plate is parallel to the horizontal plane and perpendicular to the opening direction of the collection box, so that it can swing to the front of the collection box and close the opening of the collection box, and can also swing to the top of the collection box and avoid the opening of the collection box. The baffle plate and the collection box have a locking structure to fix the baffle plate in a position that avoids the opening of the collection box; and when the baffle plate closes the opening of the collection box, the downward side of the baffle plate is flush with the lower side of the collection box to jointly support it on the horizontal plane.

[0014] In one possible implementation, the locking structure includes: A swing arm, hinged to the outer side of the baffle plate, with its hinge axis perpendicular to the hinge axis of the baffle plate; and A limiting shell is fixedly installed on the upper side of the collection box; When the baffle plate is in a position to avoid the opening of the collection box, the limiting shell is used for the swing arm to be embedded, and its inner top surface and the upper side surface of the collection box respectively abut against the upper and lower sides of the swing arm to limit the swing of the baffle plate.

[0015] In one possible implementation, the bottom of the traveling trolley has a discharge port communicating with the storage chamber, and a baffle plate for closing the discharge port is detachably connected to it.

[0016] In this embodiment, the traveling trolley is capable of moving along the bottom surface of the culvert. As the trolley moves forward, it pushes sludge forward through the collection bin on its front side, causing it to accumulate. During this process, because the collection bin has a forward-facing opening, the accumulated sludge continuously enters the bin and, under the action of the feeding assembly, continues to penetrate into the working range of the crushing assembly. Subsequently, the crushing assembly can break up the sludge, preventing clumps of sludge from forming in the collection bin and thus preventing sludge blockage. This allows the sludge to be discharged into the storage chamber via the extraction assembly.

[0017] In the above process, because the sludge is first pushed into the collection box by the external sludge, and then given the backward momentum by the feeding assembly, the sludge will not move backward into the open of the collection box when the crushing assembly acts on it, thus keeping the sludge content within a safe range. Furthermore, since the sludge inside the collection box does not flow out in any direction, the speed of the traveling trolley can be set relatively high, increasing the initial velocity of the sludge entering the collection box. This, in turn, increases the working efficiency of the feeding and crushing assemblies, effectively improving the sludge treatment efficiency.

[0018] The anti-clogging automatic sludge extraction device provided in this embodiment, compared with the prior art, can continuously extract sludge pushed by the traveling trolley. During the extraction process, the sludge can be pushed and broken up, avoiding blockage of the sludge from the opening of the collection box, the inside of the collection box, and the channel of the extraction component. This allows the device to operate continuously and improves the efficiency of sludge treatment. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0025] Please refer to the following: Figures 1 to 11 The anti-clogging automatic sludge extraction device provided in this application will now be described. The anti-clogging automatic sludge extraction device proposed in this application includes a traveling trolley 1, a collection box 2, a feeding assembly 3, and a crushing assembly 4.

[0026] The traveling trolley 1 is used to move within the culvert. Its movement is automatically driven, specifically by a drive unit connected to the front or rear axle of the traveling trolley 1 to rotate it, allowing the traveling trolley 1 to move in a straight line. In this embodiment, the direction of movement of the traveling trolley 1 within the culvert is defined as from back to front. Furthermore, this traveling trolley 1 has a storage chamber 11 for containing sludge. This storage chamber 11 can be an internal structure of the traveling trolley 1 or an external, detachable component.

[0027] The collection box 2 is located in front of the traveling trolley 1, that is, on the side that the traveling trolley 1 faces when it is working, and it has priority in contacting the silt before the traveling trolley 1. The collection box 2 has a hollow interior and an open front, and its bottom is designed to contact the bottom surface of the culvert so that when the traveling trolley 1 moves forward, the silt can enter the interior of the collection box 2 from the open opening; in addition, the width of the collection box 2 in the left-right direction is greater than the width of the traveling trolley 1.

[0028] The rear end of the collection box 2 is connected to the storage chamber 11 via the material extraction component 5, which is used to discharge the sludge in the collection box 2 into the storage chamber 11.

[0029] The feeding assembly 3 is located at the opening of the collection box 2 and is used to provide a backward force to the sludge passing through the opening of the collection box 2.

[0030] The crushing component 4 is located inside the collection box 2 and behind the feeding component 3. It is used to crush the clumps of sludge so that the sludge can enter the storage chamber 11 through the pumping component 5.

[0031] In this embodiment, the traveling trolley 1 has the ability to move on the bottom surface of the culvert. As the traveling trolley 1 moves forward, the sludge in front of it is pushed forward by the collection box 2, causing it to accumulate. During this process, because the collection box 2 has a forward-facing opening, the accumulated sludge continuously enters the collection box 2 and, under the action of the feeding component 3, continues to penetrate into the working range of the crushing component 4. Subsequently, the crushing component 4 can crush the sludge, preventing the presence of clumps of sludge in the collection box 2, thereby preventing sludge blockage in the collection box 2, so that the sludge can be discharged into the storage chamber 11 by the extraction component 5.

[0032] In the above process, since the sludge is first pushed into the collection box 2 by the external sludge, and then given the backward momentum by the feeding component 3, the sludge will not move backward into the opening of the collection box 2 when the crushing component 4 acts on it, thus preventing the sludge from accidentally moving back into the opening of the collection box 2. This keeps the sludge content within a safe range during the pushing process. Furthermore, since the sludge in the collection box 2 does not flow out in any direction, the speed of the traveling trolley 1 can be set relatively high, increasing the initial speed of the sludge entering the collection box 2. This, in turn, increases the working efficiency of the feeding component 3 and the crushing component 4, effectively improving the sludge treatment efficiency.

[0033] The anti-clogging automatic sludge extraction device provided in this embodiment, compared with the prior art, can continuously extract the sludge pushed by the traveling trolley 1, and can push and break the sludge during the extraction process, avoiding blockage of the sludge from the opening of the collection box 2, the inside of the collection box 2, and the channel of the extraction component 5, thereby enabling the device to operate continuously and improving the sludge treatment efficiency.

[0034] In some embodiments, such as Figure 6 , Figure 7 and Figure 10 As shown, the feeding assembly 3 includes a first rotating roller 31 and multiple feeding plates 32.

[0035] The first rotating roller 31 is rotatably positioned at the opening of the collection box 2. Its axial direction and rotational direction are both parallel to the horizontal plane and perpendicular to the opening direction of the collection box 2, i.e., the left-right direction.

[0036] Multiple feeding plates 32 are spaced apart around the first rotating roller 31; each feeding plate 32 is connected to the outer wall of the first rotating roller 31 and extends outward along the radial direction of the first rotating roller 31.

[0037] The first roller 31 is connected to a rotation drive component 6 for driving its rotation.

[0038] By adopting the above technical solution, when the first roller 31 rotates, the feeding plate 32 can push the sludge passing through the opening of the collection box 2 inward to enter the working range of the crushing assembly 4.

[0039] In some embodiments, such as Figure 7 and Figure 11 As shown, the crushing assembly 4 includes two second rotating rollers 41 and two sets of crushing teeth 42.

[0040] Two second rollers 41 are spaced apart in the collection box 2 in the vertical direction, and are both located behind the first roller 31; each second roller 41 is rotatably connected to the collection box 2, and its axial direction and rotational direction are parallel to the first roller 31, that is, in the left and right direction.

[0041] One of the second rollers 41 is connected to the first roller 31 through a first synchronous transmission structure 7, and the two second rollers 41 are connected through a second synchronous transmission structure 8. This is so that when the first roller 31 rotates, the second roller 41 connected to the first synchronous transmission structure 7 rotates synchronously under the action of the first synchronous transmission structure 7. At the same time, the second synchronous transmission structure 8 drives the other second roller 41 to rotate, thus achieving the technical purpose of synchronous rotation of the two second rollers 41. The two second rollers 41 rotate in the same direction (i.e., both rotate clockwise or both rotate counterclockwise).

[0042] Two sets of crushing teeth 42 are respectively disposed on the outer walls of the two second rotating rollers 41. Each set of crushing teeth 42 includes a plurality of crushing teeth 42 disposed along the axial direction of the second rotating roller 41. In this embodiment, each crushing tooth 42 includes a plurality of protruding teeth disposed at intervals along the circumference of the second rotating roller 41.

[0043] In this embodiment, a material passage gap is formed between the two second rollers 41, allowing sludge to pass through.

[0044] By adopting the above technical solution, when the two second rollers 41 rotate synchronously in the same direction (i.e., both rotate clockwise or both rotate counterclockwise), the two sets of crushing teeth 42 can pass through the material gap in opposite directions to crush the sludge.

[0045] In some embodiments, such as Figure 4 and Figure 6 As shown, the first synchronous transmission structure 7 includes a drive wheel 71, a driven wheel 72, and a first synchronous belt 73.

[0046] The drive wheel 71 is coaxially connected to the first roller 31.

[0047] Driven wheel 72 is coaxially connected to one of the second rollers 41.

[0048] The first synchronous belt 73 is wrapped around the outer periphery of the drive wheel 71 and the driven wheel 72 so that the drive wheel 71 and the driven wheel 72 rotate synchronously.

[0049] In some embodiments, such as Figure 4 , Figure 6 and Figure 11 As shown, the second synchronous transmission structure 8 includes a follower wheel 81 and a second synchronous belt 82.

[0050] The follower wheel 81 is coaxially connected to another second roller 41.

[0051] The second synchronous belt 82 wraps around the outer periphery of the driven wheel 72 and the follower wheel 81 so that the driven wheel 72 and the follower wheel 81 rotate synchronously in the same direction (i.e., both rotate clockwise or both rotate counterclockwise).

[0052] In some embodiments, such as Figure 2 and Figure 7 As shown, the rotation drive component 6 includes a rotation motor 61 and a driven helical gear 62.

[0053] The rotating motor 61 is fixedly installed on the outside of the collection box 2. Its power output axis is perpendicular to the axis of the first rotating roller 31, and the power output end of the rotating motor 61 is coaxially connected to the active helical gear 611.

[0054] Driven helical gear 62 is coaxially connected to the first roller 31 and meshes with driving helical gear 611.

[0055] By adopting the above technical solution, when the rotating motor 61 starts, the driven helical gear 62 rotates synchronously with the driving helical gear 611, and drives the first rotating roller 31 to rotate synchronously.

[0056] In some embodiments, such as Figure 1 and Figure 3 As shown, the material extraction assembly 5 includes a mud pump 51 and a material passage pipe 52.

[0057] The mud pump 51 is fixedly installed on the top of the traveling trolley 1, and its discharge end is connected to the storage chamber 11.

[0058] One end of the feed pipe 52 is connected to the feed end of the mud pump 51, and the other end is fixed to the rear end face of the collection box 2 and connected to the inside of the collection box 2.

[0059] The feed pipe 52 is made of rigid material to fix the position of the collection box 2 relative to the traveling trolley 1, thus simultaneously completing the conveying of sludge and fixing of the collection box 2.

[0060] In some embodiments, such as Figure 1 , Figure 6 and Figure 7 As shown, a baffle plate 21 is hinged to the opening of the collection box 2.

[0061] The hinge axis of the baffle plate 21 is parallel to the horizontal plane and perpendicular to the opening direction of the collection box 2, so that it can swing to the front of the collection box 2 and close the opening of the collection box 2, and can also swing to the top of the collection box 2 and avoid the opening of the collection box 2.

[0062] The baffle plate 21 and the collection box 2 are equipped with a locking structure 9 to fix the baffle plate 21 in a position that avoids the opening of the collection box 2. Furthermore, when the baffle plate 21 closes the opening of the collection box 2, the downward-facing side of the baffle plate 21 is flush with the lower side of the collection box 2 to jointly support it on the horizontal plane, ensuring the stability of the baffle plate 21. Simultaneously, an upward-facing opening can be formed between the collection box 2 and the baffle plate 21 to facilitate cleaning of the interior of the collection box 2 by operators.

[0063] In some embodiments, such as Figure 2 , Figure 8 and Figure 9 As shown, the locking structure 9 includes a swing arm 91 and a limiting shell 92.

[0064] The swing arm 91 is hinged to the outer side of the baffle plate 21, and its hinge axis is perpendicular to the hinge axis of the baffle plate 21.

[0065] The limiting shell 92 is fixedly installed on the upper side of the collection box 2.

[0066] When the baffle plate 21 is in the position to avoid the open of the collection box 2, the swing axis of the swing arm 91 is parallel to the up and down direction; at this time, the swing arm 91 can swing to be embedded in the limiting shell 92, and its inner top surface and the upper side surface of the collection box 2 respectively abut against the upper and lower sides of the swing arm 91 to limit the swing of the baffle plate 21.

[0067] In some embodiments, such as Figure 5 As shown, the bottom of the traveling trolley 1 is provided with a discharge port 12 that communicates with the storage chamber 11, and a baffle plate 13 for sealing the discharge port 12 is detachably connected.

[0068] By adopting the above technical solution, after the material blocking plate 13 is removed, the sludge can fall out of the discharge port 12 under its own gravity to realize the recycling of sludge. Under normal circumstances, the traveling trolley 1 needs to be moved to the sludge recycling unit (usually a pit opened on the ground) so that the recycled sludge can be effectively stored.

[0069] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
