Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment equipment, and in particular to a peripheral drive scraper and suction sludge machine. Background Technology

[0002] In urban wastewater treatment plants, peripheral drive sludge scrapers are mainly used for sludge scraping processes in circular sedimentation tanks. They employ central water inlet and sludge discharge, with peripheral drainage to ensure uniform water flow. For example, a peripheral drive sludge scraper disclosed in patent number CN201420113036.6 generally includes a central seat located in the center of the sedimentation tank, a working bridge rotatably connected to the central seat, and a drive device on the working bridge that rotates it on the sedimentation tank. The working bridge is equipped with a sludge collection trough, a siphon assembly, and a sludge suction assembly. The sludge suction assembly transports the sludge from the bottom of the sedimentation tank to the sludge collection trough, and then the siphon assembly transports the sludge in the sludge collection trough to the collection well at the top of the central seat, from which the sludge is discharged.

[0003] Sludge in sedimentation tanks typically has a high water content and low fluidity. Especially when the sludge concentration is high, it tends to accumulate in the collection well, leading to poor sludge discharge. In particular, after long-term use, a layer of poorly fluid sludge tends to adhere to and accumulate on the bottom and inner walls of the collection well. This not only affects the sludge discharge efficiency but also causes the liquid level in the collection well to be too high and the liquid level to drop too slowly. Consequently, the siphon component may suffer from insufficient liquid level difference, affecting its siphon effect and impacting the overall treatment effect and efficiency of the peripheral drive scraper sludge machine.

[0004] Based on this, the applicant is considering designing a peripheral drive scraper-suction sludge machine that can improve sludge discharge efficiency. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a peripheral drive scraper and suction machine that can improve the sludge discharge efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A peripheral drive scraper and suction sludge machine includes a central base, a working bridge, a sludge suction assembly, a sludge collection trough, and a siphon assembly. The working bridge is rotatably mounted on the central base, and a collection well is provided at the top of the central base. The sludge collection trough and the siphon assembly are connected to the working bridge, the sludge suction assembly is connected to the sludge collection trough, and the siphon assembly connects the sludge collection trough and the collection well. It also includes a stirring assembly connected to the working bridge so that the stirring assembly rotates with the working bridge, and the stirring assembly extends into the collection well.

[0008] The working principle and advantages of this peripheral drive scraper / suction sludge machine are as follows:

[0009] When the peripheral drive scraper-suction sludge machine is running, the working bridge rotates on the central seat, driving the sludge suction assembly, sludge collection trough, and siphon assembly to work together. The sludge suction assembly transports the sludge from the bottom of the sedimentation tank to the sludge collection trough, and then the siphon assembly transports the sludge from the sludge collection trough to the collection well at the top of the central seat, where it is finally discharged. Because the agitator assembly is connected to the working bridge, it rotates along with the working bridge, allowing the agitator assembly, which extends into the collection well, to agitate the sludge without relying on other power equipment. When the agitator assembly agitates the sludge in the collection well, it effectively prevents sludge from accumulating and avoids obstruction of sludge discharge due to sludge adhesion. The rotation of the agitator assembly enhances the fluidity of the sludge, keeping it in a flowing state and reducing the possibility of sludge accumulation, ensuring smooth discharge and improving sludge discharge efficiency. In addition, the agitator assembly also helps to avoid problems such as excessively high or slow liquid levels in the collection well, ensuring the normal operation of the siphon assembly and further improving the overall processing effect and efficiency of the peripheral drive scraper-suction sludge machine.

[0010] Furthermore, the stirring assembly abuts against the bottom side and inner wall of the collection well.

[0011] Furthermore, the stirring assembly includes a mounting ring connected to the working bridge, and a plurality of stirring plates extending into the collection well are connected to the mounting ring.

[0012] Furthermore, the siphon assembly includes a siphon tube, and the mounting ring is fixedly connected to the siphon tube.

[0013] Furthermore, the stirring assembly also includes a connector, which is detachably connected to the mounting ring, and the stirring plate is detachably connected to the connector.

[0014] Furthermore, an annular guide rail is fixedly connected to the inner side wall of the collection well, and an annular guide groove is provided on the top side of the annular guide rail, and the stirring assembly is slidably connected in the guide groove.

[0015] Furthermore, the stirring assembly also includes a first insert rod, and the connector and the stirring plate are respectively provided with a first insert hole and a second insert hole, the first insert hole and the second insert hole are located directly above the guide groove, and the end of the first insert rod passes through the first insert hole and the second insert hole in sequence and extends into the guide groove; the stirring assembly also includes a second insert rod, and the connector and the stirring plate are respectively provided with a third insert hole and a fourth insert hole, and the end of the second insert rod passes through the third insert hole and the fourth insert hole in sequence.

[0016] Furthermore, the connector includes a slot for the mounting ring to extend into, and the stirring plate has a limiting groove for the guide rail to extend into.

[0017] Furthermore, the stirring plate abuts against the bottom side and inner wall of the collection well.

[0018] Furthermore, the central seat is provided with a sludge discharge main pipe and several sludge discharge branch pipes. The bottom end of the sludge discharge branch pipe is connected to the sludge discharge main pipe, and the top end is connected to the collection well. The top end of the sludge discharge branch pipe is located on the movement trajectory of the stirring plate. Attached Figure Description

[0030] Refer to together Figures 1 to 8 This embodiment provides a peripheral drive scraper and suction sludge machine, including a center seat 120, a working bridge 110, a sludge suction assembly 131, a sludge collection trough 130, and a siphon assembly. The working bridge 110 is rotatably mounted on the center seat 120, and a collection well 140 is provided at the top of the center seat 120. The sludge collection trough 130 and the siphon assembly are connected to the working bridge 110, and the sludge suction assembly 131 is connected to the sludge collection trough 130. The siphon assembly connects the sludge collection trough 130 and the collection well 140. It also includes a stirring assembly 200 connected to the working bridge 110 so that the stirring assembly 200 rotates with the working bridge 110 and extends into the collection well 140.

[0031] In this embodiment, when the peripheral drive sludge scraper is running, the working bridge 110 rotates on the central seat 120, driving the sludge suction assembly 131, the sludge collection trough 130, and the siphon assembly to work together. The sludge suction assembly 131 transports the sludge from the bottom of the sedimentation tank to the sludge collection trough 130, and then the siphon assembly transports the sludge in the sludge collection trough 130 to the collection well 140 at the top of the central seat 120, and finally discharges it from the collection well 140. Since the stirring assembly 200 is connected to the working bridge 110, it can drive the stirring assembly 200 to rotate together when the working bridge 110 rotates, so that the stirring assembly 200 extending into the collection well 140 can be driven without relying on other power equipment. The mixing component 200 agitates the sludge within the collection well 140. This effectively prevents sludge buildup within the collection well 140, avoiding obstructed sludge discharge due to adhesion. The rotation of the mixing component 200 enhances the fluidity of the sludge, keeping it in a flowing state and reducing the likelihood of accumulation, ensuring smooth discharge and improving sludge discharge efficiency. Furthermore, the mixing component 200 minimizes the risk of excessively high or slow liquid levels in the collection well 140, ensuring the normal operation of the siphon assembly and further enhancing the overall processing effect and efficiency of the peripheral drive scraper sludge suction machine.

[0032] Preferably, such as Figures 1-3 As shown, the stirring component 200 abuts against the bottom side and inner wall of the collection well 140. By abutting against the bottom side and inner wall of the collection well 140, the stirring component 200 can directly act on the sludge accumulation area. Driven by the working bridge 110, the stirring component 200 continuously stirs the sludge in the collection well 140 as the working bridge 110 rotates, preventing the sludge from accumulating at the bottom and side walls, and avoiding the formation of a poorly fluid sludge layer due to long-term static sludge.

[0033] Preferably, such as Figures 1-4 As shown, the mixing assembly 200 includes a mounting ring 210 connected to the working bridge 110, and a plurality of mixing plates 230 extending into the collection well 140 are connected to the mounting ring 210. The mounting ring 210 is fixed to the working bridge 110, and as the working bridge 110 rotates, the plurality of mixing plates 230 rotate together, thereby improving the mixing efficiency. All the mixing plates 230 are connected to the mounting ring 210, which can improve the integrity and stability of the mixing assembly 200.

[0034] Preferably, such as Figures 1-4 As shown, the siphon assembly includes a siphon tube 150, and a mounting ring 210 is fixedly connected to the siphon tube 150. Since the siphon tube 150 is mounted on the working bridge 110, the working bridge 110 can drive the siphon tube 150 and the mixing assembly 200 to rotate together. The mounting ring 210 connects the siphon tube 150 (generally, at least two siphon tubes 150 are included in a peripheral drive scraper sludge machine) together, improving the stability of the siphon tube 150 during operation and preventing it from shaking or shifting due to vibration or external force. Specifically, the mounting ring 210 can also be connected to the working bridge 110 to further improve the stability of the mixing assembly 200 and the siphon tube 150. Furthermore, the peripheral drive scraper sludge machine also includes a vacuum pump, sludge pump, or other vacuum system connected to the siphon tube 150 to control the siphon tube 150 to form a siphon state.

[0035] Preferably, such as Figures 1 to 7 As shown, the mixing assembly 200 also includes a connector 220, which is detachably connected to the mounting ring 210, and the mixing plate 230 is detachably connected to the connector 220. The detachable connection between the mixing plate 230 and the connector 220 facilitates quick replacement when worn or damaged, reduces equipment downtime, and allows for flexible adjustment of the number and position of the mixing plate 230 according to the size of the sedimentation tank and the characteristics of the sludge.

[0036] Preferably, such as Figures 1-3As shown, an annular guide rail 141 is fixedly connected to the inner wall of the collection well 140. An annular guide groove 142 is provided on the top side of the annular guide rail 141. The stirring assembly 200 is slidably connected in the guide groove 142. As the working bridge 110 rotates, the stirring assembly 200 slides in the annular guide groove 142 to ensure that the stirring plate 230 is always in contact or abutting against the bottom side and inner wall of the collection well 140, thereby achieving effective stirring of the sludge.

[0037] Preferably, such as Figures 1 to 8 As shown, the stirring assembly 200 also includes a first insert rod 241. The connector 220 and the stirring plate 230 are respectively provided with corresponding first insertion holes 222 and second insertion holes 232. The first insertion holes 222 and second insertion holes 232 are located directly above the guide groove 142. The end of the first insert rod 241 passes through the first insertion hole 222 and the second insertion hole 232 sequentially and extends into the guide groove 142. The stirring assembly 200 also includes a second insert rod 242. The connector 220 and the stirring plate 230 are respectively provided with corresponding third insertion holes 223 and fourth insertion holes 233. The end of the second insert rod 242 passes through the third insertion hole 223 and the fourth insertion hole 233 sequentially. When the first insert rod 241 passes through the first insertion hole 222 and the second insertion hole 232 sequentially and extends into the guide groove 142, it can connect the connector 220 and the stirring plate 230 together, and also... The connector 220 and the agitator are connected to the guide rail 141 to ensure that the agitator plate 230 and the connector 220 rotate and move according to the running trajectory of the guide groove 142. The second insert 242 passes through the third insert hole 223 and the fourth insert hole 233 in sequence to connect the agitator plate 230 and the connector 220 together. The first insert 241 and the second insert 242 simultaneously connect the agitator plate 230 and the connector 220 together, which can enhance the stability of the connection between the agitator plate 230 and the connector 220. Specifically, the first insert 241 and the second insert 242 can be set to be magnetically connected to the connector 220 for easy and quick installation and disassembly. The first insert 241 and the second insert 242 can also be set to be threaded to the first insert hole 222, the second insert hole 232, the third insert hole 223 and the fourth insert hole 233 for strong stability.

[0038] Preferably, such as Figures 1 to 7 As shown, the connector 220 includes a slot 221 into which the mounting ring 210 extends, and the stirring plate 230 has a limiting groove 231 into which the guide rail 141 extends. When the connector 220 is installed, the slot 221 on it is engaged with the mounting ring 210, so that the connector 220 can fit tightly with the mounting ring 210. The limiting groove 231 on the stirring plate 230 can ensure that the stirring plate 230 rotates along the annular guide rail 141 during operation. Specifically, the connector 220 is detachably connected to the mounting plate by fixing bolts.

[0039] Preferably, such as Figures 1-3 As shown, the stirring plate 230 abuts against the inner bottom side and inner wall of the collection well 140; as the working bridge 110 rotates, the stirring assembly 200 slides in the annular guide groove 142, and the stirring plate 230 abuts against the inner bottom side and inner wall of the collection well 140, continuously stirring the sludge, which can effectively scrape off the sludge attached to the inner wall and bottom, prevent its accumulation, and maintain the fluidity of the sludge.

[0040] Preferably, such as Figure 1 As shown, the central base 120 is equipped with a sludge discharge main pipe 160 and several sludge discharge branch pipes 170. The bottom end of the sludge discharge branch pipe 170 is connected to the sludge discharge main pipe 160, and the top end is connected to the collection well 140. The top end of the sludge discharge branch pipe 170 is located on the movement trajectory of the mixing plate 230. The sludge in the collection well 140 can be discharged through multiple sludge discharge branch pipes 170, which can improve the sludge discharge efficiency of the collection well 140. The sludge discharge branch pipes 170 are located on the movement trajectory of the mixing plate 230, which can ensure that the sludge is scraped into the branch pipe in time during the mixing process, reduce the residence time of the sludge in the collection well 140, and further improve the sludge discharge efficiency.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it.
