Description

Technical Field

[0001] This utility model relates to the field of sludge scraper technology, and in particular to a high-efficiency cleaning full-bridge vertical frame peripheral drive sludge scraper. Background Technology

[0002] During the wastewater treatment process, a large amount of sludge accumulates in the sludge tank. This sludge needs to be cleaned up in a timely manner to ensure the normal operation of the wastewater treatment system.

[0003] Traditional sludge scrapers have problems such as low cleaning efficiency and incomplete cleaning when cleaning sludge. For example, traditional sludge scrapers are difficult to effectively scrape off sludge from the side walls of sludge tanks, causing sludge to accumulate on the side walls and affecting the effective volume and treatment effect of the sludge tank. At the same time, during the cleaning process, sludge easily adheres to the scraping equipment, increasing the difficulty of equipment maintenance and operating costs.

[0004] Therefore, a high-efficiency cleaning full-bridge vertical frame peripheral drive sludge scraper is proposed here to solve the above-mentioned problems. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figures 1 to 4 As shown, a high-efficiency cleaning full-bridge vertical frame peripheral drive sludge scraper includes a bridge frame 1 and a sludge scraper. The bridge frame 1 supports the sludge scraper, which is fixed on the bridge frame 1. The sludge scraper includes a motor 2, and a reducer 3 is provided at the output end of the motor 2. The reducer 3 is fixed on the bridge frame 1. The function of the reducer 3 is to reduce the speed of the motor 2 and increase the torque to meet the working requirements of the sludge scraper. A rotating shaft 21 is provided at the output end of the reducer 3, and a main shaft 22 is provided at the lower end of the rotating shaft 21. The rotating shaft 21 and the main shaft 22 are fixedly connected by bolts. This bolt-fixed connection method facilitates installation and disassembly, and makes the maintenance and repair of the equipment convenient.

[0025] The bottom of the rotating shaft 21 is provided with a bearing seat 6, which supports the rotating shaft 21 and ensures the stable rotation of the rotating shaft 21. The bottom of the bearing seat 6 is provided with a scraper seat 5, and the side wall of the rotating shaft 21 is provided with a sludge scraping device, which is used to scrape sludge from the side wall of the sludge tank.

[0026] The sludge scraping device includes a connecting rod 221, which is fixed to the side wall of the main shaft 22. A scraper frame 8 is provided on the side of the connecting rod 221. The scraper frame 8 is fixedly connected to the connecting rod 221 by bolts. The scraper frame 8 is provided with multiple scraper mounting seats 9. Two fixing rods 93 are symmetrically provided on the upper surface of the scraper mounting seat 9. A side wall scraper 92 is provided on the scraper mounting seat 9. The side wall scraper 92 can closely fit the side wall of the sludge tank and scrape off the sludge on the side wall during rotation, thereby improving the cleaning effect. The side wall scraper 92 is fixedly connected to the scraper mounting seat 9 by bolts, which facilitates the adjustment of the position and angle of the scraper frame 8 according to the actual situation.

[0027] The main shaft 22 is provided with a water pipe connector 222 on its side, and a water outlet pipe 82 is provided on the side of the water pipe connector 222. The scraper mounting seat 9 is fixed on the water outlet pipe 82. The lower end of the water outlet pipe 82 is provided with a water outlet 821. The upper end of the scraper mounting seat 9 is provided with a connecting pipe 94, which is connected to the water outlet 821. The surface of the scraper mounting seat 9 is provided with multiple nozzles 91. During the sludge scraping process, water enters the water outlet pipe 82 from the water pipe connector 222, then enters the scraper mounting seat 9 through the connecting pipe 94, and finally sprays out from the nozzles 91 to rinse the side wall scraper 92 and the side wall of the sludge tank, reducing sludge adhesion and achieving a self-cleaning function.

[0028] The main shaft 22 is equipped with a support 41 at its upper end, and a slurry pump 4 is mounted on the support 41. The output end of the slurry pump 4 is equipped with a sludge discharge pipe 42, and the input end is equipped with a sludge suction pipe 43. The sludge suction pipe 43 is fixed to the side wall of the main shaft 22 and extends to the scraper seat 5. The sludge discharge pipe 42 is fixed to the cable tray 1. After the scraper seat 5 initially scrapes the sludge at the bottom, the slurry pump 4 sucks in the sludge through the sludge suction pipe 43 and then discharges it through the sludge discharge pipe 42, achieving rapid sludge cleaning.

[0029] The main shaft 22 is provided with a mounting block 71 on the side of its lower end. The mounting block 71 is provided with bottom scrapers 7 on both sides. The bottom scrapers 7 can further scrape the sludge at the bottom of the sludge tank during the rotation of the main shaft 22 to ensure that the bottom sludge is thoroughly cleaned.

[0030] Multiple reinforcing rods 81 are provided between the water outlet pipe 82 and the scraper frame 8. The reinforcing rods 81 can enhance the connection strength between the water outlet pipe 82 and the scraper frame 8, and ensure the stability of the equipment during operation.

[0031] The working principle of this utility model is as follows: When in use, the motor 2 drives the rotating shaft 21 and the main shaft 22 to rotate through the reducer 3. The rotation of the main shaft 22 drives the side wall scraper 92 and the bottom scraper 7 to rotate. The side wall scraper 92 scrapes the sludge on the side wall of the sludge tank, and the bottom scraper 7 scrapes the sludge at the bottom of the sludge tank.

[0032] At the same time, the water source is turned on, and water enters the outlet pipe 82 from the water pipe connector 222, enters the scraper mounting seat 9 through the connector 94, and finally sprays out from the nozzle 91 to flush the side wall scraper 92 and the side wall of the sludge tank.

[0033] The sludge pump 4 starts and sucks in the sludge from the scraper seat 5 through the sludge suction pipe 43, and then discharges it through the sludge discharge pipe 42, thus cleaning the sludge.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
