Description

Technical Field

[0001] This utility model relates to the technical field of sludge silo opening and closing control devices, specifically to a sludge silo gate mechanism. Background Technology

[0002] In the field of wastewater treatment, a gate mechanism is a device used to control the opening and closing of the discharge port of a sludge silo. During wastewater treatment, solid suspended matter is generated, which is collectively referred to as sludge. After thickening and digestion, the sludge must be dewatered. The dewatered sludge becomes sludge blocks, which have solid properties and are easy to load and transport to designated locations for disposal.

[0003] In the prior art, gate mechanisms typically include a gate frame, a gate plate, and a drive mechanism that drives the gate plate to reciprocate. The gate frame is installed at the discharge port of the sludge silo. The drive mechanism includes a lead screw and a motor assembly. The motor drives the lead screw to rotate, thereby moving the gate plate. When the gate plate moves to the discharge port, it can close the discharge port, preventing the sludge in the silo from being discharged downwards. When loading is required, the drive mechanism drives the gate plate away from the discharge port, opening the discharge port. At this time, the sludge stored in the silo will be discharged from the discharge port onto the sludge loading truck located below the silo.

[0004] In practical applications, the gate may carry some sludge onto the gate frame during the opening or closing of the discharge port, which can easily cause the gate to jam during movement. This can lead to motor burnout during operation, affecting the normal movement of the lead screw and preventing the gate from opening and closing properly. In particular, when the gate is in the open position, motor damage can prevent the gate from closing. At this time, the sludge-loading truck has reached its maximum loading limit. After the truck leaves, the sludge in the hopper continues to fall to the ground because the gate cannot close properly, causing ground pollution and making it inconvenient to clean. Utility Model Content

[0005] This utility model provides a sludge silo gate mechanism, the purpose of which is to activate emergency measures when the drive mechanism fails to drive the screw to close the gate, causing sludge to fall continuously, so as to avoid a large amount of sludge falling into the silo and causing pollution, and to prevent the sludge from being difficult to clean.

[0006] This utility model is achieved through the following technical solution: a sludge silo gate mechanism, including a gate frame, a gate plate, and a drive mechanism. The gate frame is installed at the discharge port of the silo, and the gate plate is located inside the gate frame. An opening is provided on one side of the discharge port of the silo, and the gate plate can be inserted laterally through the opening to cut off the discharge port. The drive mechanism includes a lead screw and a motor assembly. The motor assembly drives the lead screw to rotate. The gate plate is threadedly engaged with the lead screw, and the two sides of the gate plate are slidably engaged with the two sides of the gate frame. The mechanism also includes a sub-plate and a push rod. The sub-plate is located at the bottom of the discharge port and can cut off the discharge port. The two sides of the sub-plate are respectively horizontally slidably engaged with the two sides of the gate frame. The push rod is detachably engaged with the sub-plate.

[0007] Compared with existing technologies, this solution has the following advantages and beneficial effects:

[0008] In this solution, when the drive mechanism fails to drive the lead screw to open or close the gate, an emergency measure can be activated. That is, the push rod drives the auxiliary plate to slide towards the discharge port, thereby closing and cutting off the discharge port. This effectively avoids the situation where a large amount of sludge falls into the silo, causing pollution and making it difficult to clean.

[0009] In this design, a secondary plate capable of cutting off the discharge outlet is installed at the bottom of the outlet. The two sides of the secondary plate slide horizontally with the two sides of the gate frame. By applying force to the push rod, the push rod drives the secondary plate to slide. Under normal circumstances, the push rod drives the secondary plate to slide away from the discharge outlet, so that the cutting off and opening of the discharge outlet is controlled by the movement of the gate plate along the screw axis. However, when the motor assembly is damaged and the screw cannot rotate normally, in order to prevent the gate plate from failing to cut off the discharge outlet and causing sludge to continuously fall to the ground and cause pollution, force can be applied to the push rod to drive the secondary plate to slide towards the discharge outlet, and the secondary plate is located at the bottom of the discharge outlet to cut off the sludge and prevent the sludge from continuously falling.

[0010] The method of closing the discharge port by sliding the auxiliary plate in this solution is more efficient and can quickly close the discharge port in case of emergency.

[0011] Furthermore, a movable component is connected to one end of the gate, the movable component is located outside the discharge port, and the movable component is threadedly connected to the lead screw.

[0012] In this design, the movable part at one end of the gate is located outside the discharge port and is threadedly connected to the lead screw, thereby driving the gate to move along the axial direction of the lead screw. The movable part makes it easier to connect and cooperate with the lead screw, thus indirectly driving the gate to close or open the discharge port.

[0013] Furthermore, the moving component includes a moving block and a connecting seat. The moving block is located on top of the gate and is fixedly connected to the gate. The connecting seat is fixedly connected to the moving block. The lead screw is threadedly connected to the connecting seat. The moving block has a through hole coaxial with the lead screw. The two ends of the moving block are horizontally slidingly engaged with the two sides of the gate frame. When the moving block abuts against the outer side of the discharge port, the gate completely cuts off the discharge port.

[0014] The movable component in this solution includes a movable block and a connecting component. The movable component is used to achieve a horizontal sliding fit with the gate frame, ensuring that the gate and the movable component move smoothly along the axial direction of the lead screw. The connecting seat makes it easier to connect and fit with the lead screw. The through hole opened on the movable block can ensure the axial displacement of the movable block on the lead screw, and avoid interference with the lead screw during the movement. The lead screw can pass through the through hole.

[0015] In addition, in this solution, the moving block can abut against the outside of the discharge port, and when the two abut against each other, the gate is in a state of completely closing the discharge port. This can serve as a prompt for the gate to be closed in place, making the movement position of the gate more precise.

[0016] Furthermore, the end of the lead screw away from the gate plate extends through one end of the gate frame, and the motor assembly is fixedly installed on the gate frame. The motor assembly includes a motor, a worm gear, and a worm. The output shaft of the motor is coaxially and fixedly connected to the worm. The worm gear is coaxially and fixedly connected to the lead screw, and the worm gear meshes with the worm.

[0017] In this design, the motor assembly transmits motor power through a worm gear, and can also transmit motion and power between two intersecting shafts. This allows the motor to be installed vertically, saving installation space and making it easy to vertically fix the motor assembly to the gate frame to transmit rotational torque to the lead screw.

[0018] Furthermore, a rocker assembly is coaxially fixedly connected to the worm gear, and rotating the rocker assembly can drive the worm gear to rotate.

[0019] In this solution, the rocker assembly can rotate the worm gear when the motor assembly burns out, thereby rotating the lead screw. This allows the rocker assembly to activate an emergency plan when the gate is not closed and the motor assembly cannot rotate the lead screw smoothly. The rocker assembly will then rotate the lead screw, thereby closing the gate and preventing sludge from continuously falling and causing large-scale pollution.

[0020] This solution provides another way to close the discharge port in an emergency. This makes it easier to choose the method of closing the gate in an emergency according to the actual situation on site. You can choose to close the discharge port by sliding the auxiliary plate, or you can choose to rotate the rocker assembly to drive the screw to reverse so that the gate closes the discharge port.

[0021] Furthermore, the rocker assembly includes a sleeve and a rocker arm, the sleeve being coaxially and fixedly connected to the worm gear, and the rocker arm being detachably connected to the sleeve.

[0022] In this design, the sleeve in the rocker assembly is fixedly connected to the worm gear, while the rocker and the sleeve are detachably connected. This allows the rocker and sleeve to be connected and engaged to shut off the discharge port when emergency measures are needed. When the equipment is running normally and emergency measures are not required, the rocker and sleeve can be separated to reduce space occupation.

[0023] Furthermore, the bottom of the sleeve is provided with a groove, the top of the rocker arm is connected with a protrusion, the protrusion can be inserted into the groove, the groove is provided with insertion holes on both sides, the protrusion is provided with mounting grooves on both sides, and insertion blocks are horizontally slidably fitted in the mounting grooves, and springs are connected between the insertion blocks and the mounting grooves, and the two insertion blocks can be inserted into the two insertion holes respectively.

[0024] In this design, the protrusion at the top of the rocker arm engages with the groove, and the protrusion and groove are connected by a plug and a socket. When the plug is inserted into the socket, the rocker arm is connected to the sleeve. Rotating the rocker arm at this time will drive the sleeve and worm gear to rotate. When it is necessary to separate the rocker arm and the sleeve, pull the rocker arm down. At this time, the plug will be squeezed by the inner wall of the sleeve groove, which will compress the spring. The plug will gradually disengage from the socket. Continuing to pull the rocker arm down will separate the protrusion at the top of the rocker arm from the groove of the sleeve, thereby achieving the disassembly of the rocker arm and the sleeve.

[0025] Furthermore, a cross groove is provided at the bottom of the sleeve, and a cross block that cooperates with the cross groove is connected to the top of the rocker arm. The cross block can be inserted into the cross groove.

[0026] In this design, when the cross block at the top of the rocker arm is inserted into the cross groove at the bottom of the sleeve, the sleeve can be rotated by turning the rocker arm. The matching structure of the cross block and the cross groove in this design is simpler, the manufacturing cost is lower, and it is more convenient to use.

[0027] Furthermore, a connecting cylinder is fixedly connected to the top end of the push rod, and a push block is fixedly connected to the bottom end of the sub-plate. The top end of the connecting cylinder is an open end, and the connecting cylinder can be fitted over the outside of the push block.

[0028] In this design, the connecting cylinder at the top of the push rod and the push block at the bottom of the sub-plate are detachably connected. This means that when in use, the push rod only needs to be connected with the connecting cylinder to facilitate pushing the sub-plate, and when not in use, the push rod can be removed and stored, avoiding the problem of the push rod hanging and occupying space, thus preventing obstruction and interference.

[0029] Furthermore, scrapers are vertically connected to both sides of the sub-plate, and one side of the scraper can abut against the inner sidewall of the gate frame.

[0030] In this design, scrapers are connected to both sides of the auxiliary plate. By periodically sliding the auxiliary plate, the scrapers can remove the sludge remaining on both sides of the gate frame, reducing the sludge accumulation on the gate frame. This facilitates the smooth movement of the gate and improves the service life of the entire mechanism. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0044] Example 1

[0045] like Figures 1-2 As shown, this embodiment 1 provides a sludge silo gate mechanism, including a gate frame 4, a gate plate 6 and a drive mechanism 5. The gate frame 4 is installed at the discharge port 3 of the silo 1. The discharge port 3 is located inside the gate frame 4 and is welded or bolted to the gate frame 4. The bottom of the silo 1 is connected to a discharge hopper 2. The discharge port 3 is located at the bottom of the discharge hopper 2. The discharge hopper 2 facilitates the guidance of the sludge in the silo 1 so that the sludge falls from the discharge port 3. The discharge port 3 is a rectangular discharge port.

[0046] The gate 6 is located inside the gate frame 4, which is a rectangular frame structure. An opening is provided on one side of the discharge port 3 of the hopper 1, such as... Figure 1 In this embodiment, the opening is made on the right side of the discharge port 3. The shape of the opening matches the shape of the gate 6. The gate 6 can be inserted laterally through the opening to cut off the discharge port 3.

[0047] The drive mechanism 5 includes a lead screw 7 and a motor assembly. The motor assembly drives the lead screw 7 to rotate. The gate 6 is threadedly engaged with the lead screw 7, and the two sides of the gate 6 are slidably engaged with the two sides of the gate frame 4. Specifically, a moving part is connected to one end of the gate 6. The moving part is located outside the discharge port 3 and is threadedly connected to the lead screw 7. Figure 1 and Figure 2 As shown, in this embodiment, the movable component includes a movable block 601 and a connecting seat 9. The movable block 601 is located on the top of the gate plate 6 and is fixedly connected to the gate plate 6. In this embodiment, the movable block 601 is vertically welded or fixed to the top of the gate plate 6 by screws, and no specific limitation is made here.

[0048] Combination Figure 2As shown, the connecting seat 9 is welded and fixedly connected to the moving block 601. The connecting seat 9 is hollow. The lead screw 7 is threadedly connected to the connecting seat 9. The moving block 601 has a through hole coaxial with the lead screw 7. In this way, when the moving part moves along the lead screw 7, the lead screw 7 can pass through the through hole, thereby ensuring the smooth movement of the moving part and driving the gate 6 to move.

[0049] In this embodiment, the two ends of the movable block 601 are horizontally slidingly engaged with the two sides of the gate frame 4, specifically: as follows: Figure 2 As shown, two sliding grooves 602 are horizontally opened on the two inner side walls of the gate frame 4. Sliding blocks 603 are fixedly connected to both ends of the moving block 601. The two sliding blocks 603 are respectively inserted into the two sliding grooves 602 and can slide horizontally along the sliding grooves 602, thereby realizing the horizontal sliding cooperation between the moving block 601 and the gate frame 4. Since the moving block 601 is fixedly connected to the gate plate 6, the horizontal sliding cooperation between the moving block 601 and the gate frame 4 indirectly realizes the horizontal sliding cooperation between the gate plate 6 and the gate frame 4.

[0050] like Figure 1 As shown, when the moving block 601 abuts against the outer side of the discharge port 3, the gate 6 completely cuts off the discharge port 3. In this way, the moving block 601 plays a positioning role for the gate 6. When the moving block 601 abuts against the outer side of the discharge port 3, the gate 6 is in the closed position, which is convenient for staff to observe.

[0051] Combination Figure 1 and 2 As shown, the end of the lead screw 7 away from the gate plate 6 passes through one end of the gate frame 4. In this embodiment, an mounting block 8 is welded and fixed on the right side wall of the gate frame 4. The lead screw 7 passes through the mounting block 8 and the gate frame 4 in sequence. The mounting block 8 can support and guide the lead screw 7.

[0052] Combination Figure 1 and Figure 3 As shown, in this embodiment, the motor assembly is fixedly mounted on the gate frame 4. The motor assembly includes a motor 501, a worm gear, and a worm 505. The output shaft of the motor 501 and the worm 505 are coaxially and fixedly connected via a coupling. The worm gear and the lead screw 7 are coaxially and fixedly connected via a key and keyway. The worm gear meshes with the worm 505, as shown in the figure. Figure 1 As shown, in this embodiment, a fixing plate 10 is fixedly connected to the right end of the gate frame 4 by bolts, combined with... Figure 3As shown, a flange 502 is fixed to the housing of motor 501. Motor 501 is vertically fixed to the top of gate frame 4 via flange 502 and bolts. A first housing 503 is integrally fixed to the end of flange 502. A second housing 504 is integrally connected to one side of the first housing 503. The first housing 503 and the second housing 504 are arranged perpendicular to each other and are integrally formed. Worm 505 is located inside the first housing 503 and rotates with the first housing 503 through a bearing. Worm wheel is located inside the second housing 504. Lead screw 7 passes through the second housing 504 and is fixedly connected to the worm wheel located inside the second housing 504. The first housing 503 and the second housing 504 are interconnected, which facilitates the interaction between worm 505 and worm wheel.

[0053] like Figure 1 As shown, the sludge silo gate mechanism in this embodiment also includes a secondary plate 17 and a push rod 18. The secondary plate 17 is located at the bottom of the discharge port 3 and can cut off the discharge port 3. The two sides of the secondary plate 17 are respectively horizontally slidingly engaged with the two sides of the gate frame 4. Specifically, in this embodiment, guide grooves 19 are horizontally formed along the length of the two inner sidewalls of the gate frame 4, combined with... Figure 4 As shown, guide blocks 172 are fixedly connected to both sides of the sub-plate 17. The guide blocks 172 on both sides of the sub-plate 17 are respectively inserted into the two guide grooves 19 of the gate frame 4 and can slide along the two guide grooves 19.

[0054] In this embodiment, the push rod 18 and the sub-plate 17 are detachably connected. Specifically, a connecting cylinder 181 is fixedly connected to the top of the push rod 18. In this embodiment, the connecting cylinder 181 is integrally formed with the push rod 18, welded, or fixed in other ways. A push block 171 is fixedly connected to the bottom of the sub-plate 17. The push block 171 is welded, screwed, or fixed in other ways to the sub-plate 17. The top of the connecting cylinder 181 is an open end, and the connecting cylinder 181 can be fitted over the outside of the push block 171. This facilitates the sliding of the sub-plate 17 by the push rod 18. When the sub-plate 17 does not need to be pushed normally, it is slid to the discharge port 3. On the other hand, the discharge port 3 can be cut off or opened by controlling the movement of the gate 6. If the motor assembly fails and the screw 7 cannot rotate normally, and the discharge port 3 is in the open state, the emergency measures are activated. The push rod 18 moves towards the push block 171 at the bottom of the auxiliary plate 17, so that the connecting cylinder 181 at the top of the push rod 18 is inserted into the push block 171. Then the push rod 18 moves towards the discharge port 3, thereby pushing the auxiliary plate 17 towards the discharge port 3 until the auxiliary plate 17 cuts off and closes the discharge port 3. This can prevent sludge from continuously falling from the discharge port to the ground and causing large-scale pollution.

[0055] Example 2

[0056] like Figure 5As shown, the difference between this embodiment and embodiment 1 is that a rocker assembly is coaxially fixedly connected to the worm 505, and rotating the rocker assembly can drive the worm 505 to rotate.

[0057] The rocker assembly in this embodiment includes a sleeve 11 and a rocker arm 12. The sleeve 11 is coaxially and fixedly connected to the worm gear 505. In this embodiment, the sleeve 11 and the worm gear 505 are fixedly connected by threads, screws, or other means. In this embodiment, the rocker arm 12 and the sleeve 11 are detachably connected. Specifically: combined with... Figure 5 and Figure 6 As shown, in this embodiment, the bottom of the sleeve 11 is provided with a groove, and the top of the rocker arm 12 is connected with a protrusion 121. The protrusion 121 can be inserted into the groove. Insertion holes 13 are provided on both sides of the groove, and mounting grooves 14 are provided on both sides of the protrusion 121. Insertion blocks 15 are horizontally slidably fitted in the mounting grooves 14. A spring 16 is connected between the insertion blocks 15 and the mounting grooves 14. The two insertion blocks 15 can be inserted into the two insertion holes 13 respectively. In this embodiment, the upper and lower parts of the insertion blocks 15 are chamfered to form mutually symmetrical inclined surfaces. In this way, when the insertion blocks 15 are inserted into the insertion holes 13 and when the insertion blocks 15 are removed from the insertion holes 13, the insertion blocks 15 can compress the spring 16 and achieve horizontal displacement in the mounting grooves 14 by abutting against the side wall of the sleeve 11 through the inclined surfaces of their upper and lower parts. This facilitates the insertion blocks 15 to be smoothly inserted into or removed from the insertion holes 13, realizing the connection and disassembly between the rocker arm 12 and the sleeve 11.

[0058] In this embodiment, by setting up a rocker assembly, in the event that the motor assembly fails and cannot drive the lead screw 7 to rotate, the rocker 12 is inserted into the sleeve 11, and then the rocker 12 is rotated to drive the worm gear 505 to rotate, thereby driving the lead screw 7 to rotate. This facilitates the movement of the gate 6 to the discharge port to cut off the discharge and prevent the sludge from continuously falling. Based on Embodiment 1, this embodiment also provides an emergency method for closing the discharge port. The gate 6 is moved by manually driving the lead screw 7 to rotate. This provides multiple methods for emergency closing of the discharge port in practice, facilitating flexible use.

[0059] Example 3

[0060] The difference between this embodiment and Embodiment 2 is that: Figure 7 As shown, in this embodiment, the bottom of the sleeve 11 is provided with a cross groove, and the top of the rocker arm 12 is connected to a cross block that cooperates with the cross groove. The cross block can be inserted into the cross groove. Of course, the cross groove structure can also be set as a straight groove structure, and the corresponding cross block is set as a straight block that cooperates with the straight groove.

[0061] In this design, the rocker arm 12 engages with the cross groove at the bottom of the sleeve 11 via a cross block, enabling quick connection between the rocker arm 12 and the sleeve 11. This also simplifies the connection structure and manufacturing process.

[0062] Example 4

[0063] The difference between this embodiment and Embodiment 1 is that: Figure 8 and Figure 9 As shown, scrapers 20 are vertically connected to both sides of the sub-plate 17. The scrapers 20 are welded to the sub-plate 17, screwed to it, or connected in other ways. In this embodiment, three scrapers 20 are provided on each side of the sub-plate 17. The three scrapers 20 are distributed at intervals along the length of the sub-plate 17. One side of the scraper 20 can abut against the inner wall of the gate frame 4.

[0064] In this embodiment, the scraper 20 is moved by periodically sliding the auxiliary plate 17, thereby scraping off the sludge remaining on both sides of the gate frame 4, reducing the sludge accumulated on the gate frame 4. This facilitates the smooth movement of the gate plate 6, increases the service life of the entire mechanism, and reduces the probability of motor component failure.

[0065] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
