Description

Technical Field

[0001] This utility model belongs to the technical field of sewage treatment equipment, specifically relating to a high-efficiency and energy-saving overhead scraper and suction sludge machine. Background Technology

[0002] High-efficiency and energy-saving overhead sludge scrapers are widely used in wastewater treatment plants, sedimentation tanks, and dredging projects where continuous scraping and simultaneous suction of sludge from the bottom of the tank are required. These devices typically rely on an overhead trolley frame moving along a track, using metal scrapers at the bottom to push the sludge together, and then a suction mechanism at the front or bottom to pump and transport the sludge-water mixture, thereby improving the efficiency of tank bottom cleaning and ensuring the stability of subsequent treatment processes. With the expansion of the wastewater treatment industry and the increase in automation, higher demands are being placed on the operating efficiency, energy-saving performance, and continuous stability of sludge scraper equipment. However, in actual operation, the traditional suction mechanism of the overhead scraper sludge suction machine is prone to clogging during the suction process because the sludge at the bottom of the pool often contains larger soft debris such as plastic bags and aquatic plants. This leads to increased load on the suction pump or even shutdown, affecting the continuous operation of the equipment. Moreover, most existing scraper sludge suction machines lack a dedicated pre-filter structure to intercept impurities, making it difficult to remove accumulated debris in a timely manner. This results in frequent manual handling, long downtime, low maintenance efficiency, and ultimately reduced overall operational effectiveness. Utility Model Content

[0003] The purpose of this utility model is to provide a high-efficiency and energy-saving overhead scraper and suction machine to solve the problems mentioned in the background art, such as the sludge at the bottom of the pool often containing plastic bags, aquatic plants and other debris, which can easily clog the traditional suction mechanism, leading to increased load on the suction pump or even shutdown. In addition, the lack of a front-end interception structure makes it difficult to clean debris in a timely manner, resulting in frequent shutdowns, low maintenance efficiency and affecting the overall operation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency and energy-saving overhead scraper and suction machine, comprising an overhead main frame and a hoisting mechanism disposed inside and at its bottom.

There are two lifting connection blocks, which are symmetrically welded to the front center of the metal integrated strip on both sides. The top of each of the two lifting connection blocks is vertically welded downward. The metal rod can drive the metal integrated strip to move up and down through the lifting connection block. When the metal integrated strip is inserted between the L-shaped bracket and the metal bottom frame, the top of each of the two metal rods is located above the front end of the main frame of the crane.

[0007] Preferably, the sludge suction and anti-blockage device further includes a lifting crossbar, a screw fixing plate, and position fixing screws. The lifting crossbar is welded between the tops of two metal lifting rods. After it is connected to an external crane, the metal integrated plate and the L-shaped large impurity collection rake teeth at its bottom end can be lifted by the crane. The screw fixing plate is welded between the two metal lifting rods and is located below the lifting crossbar. When the metal integrated plate is inserted between the L-shaped bracket and the metal bottom frame, the screw fixing plate can be fixed to the front end of the main frame of the crane by multiple position fixing screws.

[0008] Preferably, the main frame of the crane is welded with U-shaped groove wheel seats at both ends. Both U-shaped groove wheel seats are arranged longitudinally, and the U-shaped openings at the front and rear ends of the two U-shaped groove wheel seats are equipped with crane wheels. The top of the rear end of the U-shaped groove wheel seat on the left and the top of the front end of the U-shaped groove wheel seat on the right are fixed with crane motors through the frame plate. Both crane motors are connected to the corresponding crane wheels through transmission chains.

[0009] Preferably, the trolley motor is electrically connected to an external power source, and it can drive the trolley wheels connected to it to rotate through a transmission chain. The trolley wheels on the two U-shaped groove wheel seats are respectively placed on two tracks, so that the trolley wheels can move back and forth on the corresponding tracks after being driven by the trolley motor.

[0010] Preferably, the top of both the front and rear ends of the main frame of the vehicle is provided with a guardrail laterally, and a platform plate is welded inside the top frame, while the hoisting mechanism is located below the platform plate.

[0011] Preferably, the hoisting mechanism includes an I-shaped hanger, reinforcing connecting rods, screw fixing plates, and a metal top frame. Multiple metal top frames are provided and are welded at equal intervals to the center of the main frame of the crane and the interior of its left and right sides. The bottom ends of the multiple metal top frames are fixed with I-shaped hangers by screw fixing plates. The I-shaped hangers are arranged in a downward vertical state, and the metal bottom frame is fixed to the bottom ends of the multiple I-shaped hangers by welding.

[0014] Compared with the prior art, this utility model provides a high-efficiency and energy-saving overhead scraper and suction machine, which has the following beneficial effects: This utility model adds a novel anti-blocking device to the front of the suction mechanism of the overhead scraper sludge suction machine. When the overhead scraper sludge suction machine runs from back to front, the anti-blocking device can collect large impurities in the sludge before the suction mechanism, such as plastic bags and aquatic plants, to avoid the suction mechanism from being blocked by plastic bags or aquatic plants in the sludge. In addition, after the suction is completed, the anti-blocking device will collect a large number of plastic bags or aquatic plants. By simply connecting the lifting bar to the lifting mechanism and lifting the device, the plastic bags or aquatic plants collected by the device can be quickly cleaned up. The device features an L-shaped large-piece impurity collection rake with its lower half extending forward longitudinally and its upper half set vertically. This allows it to actively intercept and grab large impurities such as plastic bags and aquatic plants from the sludge as the sludge scraper moves forward, preventing debris from entering the suction pipe head and collection pipe at the source, thus preventing blockage of the suction mechanism and ensuring continuous sludge suction operations. The integrated metal strip and L-shaped bracket work together to achieve quick positioning and locking of the device to the metal base frame, ensuring a stable connection and preventing displacement due to vibration during sludge scraper operation. It can also slide out from bottom to top, and with the lifting crossbar and metal rod, it is easy to disassemble and lift as a whole, quickly cleaning the collected impurities. The operation is convenient and efficient. Furthermore, the device forms a complete lifting structure through the lifting connecting block, metal rod, and lifting crossbar, eliminating the need for additional disassembly of complex parts. It can be lifted and cleaned simply by connecting to an external crane, reducing downtime for maintenance and improving the working efficiency of the sludge scraper. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-6The high-efficiency energy-saving overhead sludge scraper shown includes an overhead main frame 9 and a hoisting mechanism 3 installed inside and at its bottom. The overhead main frame 9 serves as the main load-bearing component, and multiple sets of metal top frames 20 are installed inside. The metal top frames 20 are reliably connected to the lower I-shaped hangers 17 by screw fixing plates 19. The I-shaped hangers 17 are arranged vertically and have multiple reinforcing connecting rods 18 inside. Multiple reinforcing connecting rods 18 are also installed inside the multi-metal bottom frame 1, forming a rigid integral structure between the metal bottom frame 1 and the overhead main frame 9. The platform plate 10 is fixed to the top area of ​​the overhead main frame 9, and guardrails 11 are arranged on both sides of the platform plate 10 to provide safety protection for the upper operating space. The sludge suction pumps 16 are arranged on the upper surface of the platform plate 10, and the two sludge suction pumps 16 are symmetrically positioned. The metal bottom frame 1 is located at the bottom of the entire sludge scraper mechanism 4, and metal scraper blades 2 are installed at its bottom area. Extending laterally, the metal scraper 2 is firmly connected to the metal base frame 1 via a metal plate and several fixing screws. A sludge suction mechanism 4 is set in front of the metal scraper 2. The core of the sludge suction mechanism 4 consists of a pipe fixing frame 12, a sludge collection pipe 13, a sludge conveying pipe 14, and multiple sludge suction pipe heads 15. The pipe fixing frame 12 is arranged on the left and right bottom edges of the metal base frame 1 and is fixed by screws. The pipe fixing frames 12 at both ends are used to support the sludge collection pipe 13, so that the sludge collection pipe 13 is arranged laterally along the front of the equipment. Multiple sludge suction pipe heads 15 are opened on the lower side of the sludge collection pipe 13. Each sludge suction pipe head 15 is connected to the inside of the sludge collection pipe 13. Two sludge conveying pipes 14 are arranged above the sludge collection pipe 13. The sludge conveying pipes 14 extend to the platform plate 10 and are connected to the inlet of two sludge pumps 16 respectively. The sludge pumps 16 are firmly connected to the sludge conveying pipes 14 via flanges and screws to realize the upward conveying of sludge.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, a sludge suction anti-blocking device 5 is further forward of the sludge suction mechanism 4. This device is installed in the frontmost area of ​​the metal base frame 1 in an embedded manner. The main bearing component is a metal integrated strip plate 22. Several L-shaped large impurity collection rake teeth 23 are welded to the front edge of the metal integrated strip plate 22. Each L-shaped large impurity collection rake tooth 23 is arranged sequentially from the lower side of the metal integrated strip plate 22. The upper section of the rake tooth is set in a roughly vertical direction, while the lower section extends forward, so that it can actively cut into the sludge layer to intercept large floating objects and soft impurities during the movement of the sludge suction machine.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, to achieve the stable limiting and detachable functions of the sludge suction anti-blocking device 5, two L-shaped brackets 21 are welded to the left and right front areas of the metal base frame 1. The L-shaped brackets 21 extend upward from the outer edge of the metal base frame 1, and in the clamping space formed by them and the metal base frame 1, the metal integrated strip 22 can be limited and inserted, so that it maintains a stable front position during operation. In addition, to facilitate lifting and cleaning of impurities, multiple lifting connecting blocks 24 are welded to the front surface of the metal integrated strip 22. The lower end of the lifting connecting block 24 is fixedly installed with a metal lifting rod 25. The metal lifting rod 25 passes upward through the front end space of the main frame 9 of the crane and is connected at the top by a lifting crossbar 26. The lifting crossbar 26 is located between the two metal lifting rods 25, providing a unified force point for the external crane. When it is necessary to clean the sludge suction anti-blocking device 5, When the debris trapped by the blocking device 5 is removed, the entire metal integrated strip 22 and its attached L-shaped large impurity collection rake teeth 23 can be lifted directly by the lifting crossbar 26. In order to prevent the metal integrated strip 22 from shaking during normal operation, the strip 27 is fixed by welding screws between the metal lifting rods 25. It is connected to the main frame 9 of the trolley through multiple fixing screws 28 to ensure that the anti-blocking device is in a stable working condition. When the accumulated impurities in front of the sludge suction anti-blocking device 5 reach a certain amount, the metal lifting rod 25 drives the metal integrated strip 22 to move upward out of the L-shaped bracket 21 limit area through the connection between the external crane and the lifting crossbar 26. This can quickly complete the impurity cleaning and restore the whole machine to normal operation. Through the above structural combination, the continuous synergistic effect of anti-blocking, sludge scraping, sludge suction and rapid maintenance is achieved.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, two U-shaped grooved wheel seats 7 are distributed on both sides of the bottom of the main frame 9 of the traveling crane. Each U-shaped grooved wheel seat 7 has a traveling wheel 6 installed in its longitudinal channel. The traveling wheel 6 is placed above a preset track and can move along the track. Two sets of traveling crane motors 8 are installed at different ends of the two U-shaped grooved wheel seats 7 and are connected to their corresponding traveling wheels 6 through a transmission chain. After the traveling crane motor 8 is connected to an external power source, it can drive the traveling wheels 6 to reciprocate along the track through the transmission chain, thereby driving the entire traveling sludge scraper to move on the pool. After the equipment is put into operation, the main frame 9 of the traveling crane moves along the track, driving the entire mechanism to move. The sludge suction and anti-clogging device 5 at the front end first contacts the sludge layer. The L-shaped large impurity collection rake teeth 23 effectively intercept soft or large impurities such as plastic bags and aquatic plants in the sludge, causing them to accumulate in the area in front of the metal integrated strip plate 22. Subsequently, the metal scraper plate 2 scrapes the sludge flat and pushes the sludge into the working range of the sludge suction mechanism 4, so that multiple sludge suction pipe heads 15 approach the sludge layer to complete the sludge suction action. After the sludge is collected by the sludge suction collection pipe 13, it is transported to the sludge suction pump 16 on the platform plate 10 through the sludge suction conveying pipe 14, and then further pumped by the sludge suction pump 16 to the designated sludge treatment system.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
