Description

Technical Field

[0001] This utility model relates to the field of gantry-type scraper and suction sludge cleaning technology, specifically a gantry-type scraper and suction sludge machine that is easy to clean. Background Technology

[0002] As is well known, a gantry-type sludge scraper is a specialized device used to clean sediment from the bottom of pools, sedimentation tanks, or wastewater treatment equipment. It is typically supported by a gantry (or truss) spanning the pool, on which scraping devices and a sludge suction system are mounted. The use of this device requires the equipment or system to be designed for easy cleaning and maintenance.

[0003] In real-world applications, gantry-type sludge scrapers, designed for easy cleaning, use their cleaning brushes to scrape up sludge from the bottom of a pool, creating wastewater that is then pumped away by a sludge pump. However, when the sludge layer at the bottom is thick, the brushes struggle to clean it effectively, often resulting in incomplete cleaning and limiting its practicality. Furthermore, the wastewater tends to spread upwards in large quantities, and since the sludge pump's pipe is located near the bottom, it's difficult to collect this wastewater. When the gantry-type sludge scraper is moved to another location, the sludge in the water above settles back to the bottom, requiring multiple cleaning cycles to remove it completely. Therefore, its practicality is limited and there is room for improvement. Utility Model Content

[0012] Preferably, a telescopic rod is provided at the lower part of the vehicle body, and the lower part of the telescopic rod is fixedly connected to the upper part of the fixed plate.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a gantry-type sludge scraper that is easy to clean, and has the following beneficial effects:

[0015] This easy-to-clean gantry-type sludge scraper pumps water into a connecting pipe via a water pump and sprays water onto the sludge at the bottom of the pool through nozzles. This disperses the clumps of sludge, making it easier for the cleaning brush to clean the remaining sludge, thus improving the cleaning effect of the brush. The wastewater formed by the cleaned sludge mixed with the pool water is blocked by a dust baffle and flows along the curved end face to the collection device, which allows the sludge pump to remove the wastewater. This prevents the wastewater from spreading upwards in the pool, thereby improving its practicality. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-6 This utility model discloses a gantry-type sludge scraper / vacuum cleaner for easy cleaning, comprising a vehicle body 1, a hydraulic cylinder 2 mounted on the lower part of the vehicle body 1, a fixing plate 3 located below the hydraulic cylinder 2, and several cleaning brushes 4 located below the fixing plate 3. The vehicle body 1 drives the gantry-type sludge scraper / vacuum cleaner to move, causing the cleaning brushes 4 to scrape the mud on the bottom of the pool, thus cleaning the bottom of the pool. A water pump 5 is mounted on the upper part of the fixing plate 3, and an inlet pipe 6 is located on the upper part of the water pump 5. The water pump 5 pumps water from the external pool through the inlet pipe 6. A dust baffle 7 is provided at the front to prevent sewage mixed with mud from moving upward and spreading into the pool water above. A drain pipe 8 is provided at the lower part of the water pump 5 and passes through the upper part of the dust baffle 7. A connecting pipe 9 is provided at the lower part of the drain pipe 8. The water pump 5 pumps water into the drain pipe 8 and then into the connecting pipe 9. Several nozzles 10 are provided on one side of the connecting pipe 9. The water in the connecting pipe 9 impacts the bottom of the pool through the nozzles 10, dispersing the dust that has accumulated together, reducing the difficulty for the cleaning brush 4 to clean the bottom of the pool, and making it easier to clean the bottom of the pool.

[0025] The dust baffle 7 has an arc-shaped cross-section, which makes it easier for the water jet from the nozzle 10 to impact the bottom of the pool and wash up the mud. It moves along the arc-shaped end face towards the cleaning brush 4. There is a gap between the lower part of the dust baffle 7 and the bottom of the pool to prevent the dust baffle 7 from scraping the mud on the bottom of the pool during the movement of the vehicle body 1.

[0026] The nozzle 10 is set at an angle downwards, so that the water sprayed from the nozzle 10 can be blown to the mud at the bottom of the pool along the angled direction. The blown mud will move upwards at an angle, impact the side wall of the dust baffle 7, and flow along the arc-shaped end face. There is a gap between the nozzle 10 and the bottom of the pool to prevent the nozzle 10 from rubbing against the bottom of the pool and being damaged when the vehicle body 1 moves the nozzle 10.

[0027] A sludge pump 11 is installed on the upper part of the fixed plate 3. A first extraction pipe 12 is installed on the lower part of the sludge pump 11 and passes through the fixed plate 3. A second extraction pipe 13 is installed on the lower part of the first extraction pipe 12. Several collection devices 14 are installed on the lower part of the second extraction pipe. When the sludge pump 11 is started, the sludge pump 11 generates suction on the first extraction pipe 12 and the second extraction pipe 13. Then, the sewage blown by the nozzle 10 and the sewage after the cleaning brush 4 cleans the mud at the bottom of the pool are pumped away through the collection devices 14. A telescopic sewage pipe 17 is installed on the upper part of the sludge pump 11 and passes through the middle of the vehicle body 1. The sludge pump 11 transports the pumped sewage into the telescopic sewage pipe 17 and discharges it to the outside.

[0028] A fixing frame 15 is provided on the outside of the connecting pipe 9. The upper part of the fixing frame 15 is fixedly connected to the dust baffle 7. The fixing frame 15 is used to fix the connecting pipe 9, improve stability, and prevent shaking during use.

[0029] A telescopic rod 16 is provided at the lower part of the vehicle body 1. The lower part of the telescopic rod 16 is fixedly connected to the upper part of the fixed plate 3. The telescopic rod 16 keeps the fixed plate 3 in a state of up and down movement.

[0030] In summary, this easy-to-clean gantry-type sludge scraper operates by having the operator activate hydraulic cylinder 2, which moves the fixed plate 3 and cleaning brush 4 downwards to the bottom of the pool. Then, the vehicle body 1 is activated, moving the fixed plate 3 and cleaning brush 4 along the pool bottom. Simultaneously, water pump 5 is activated, drawing water from the top of the pool through the inlet pipe and then delivering it through the drain pipe 8 to the connecting pipe 9. The water is then sprayed obliquely onto the bottom of the pool through nozzles 10, dispersing the accumulated sludge and causing it to move upwards, impacting the end face of the dust baffle 7 and spreading along the end face. The collection device 14 moves in one direction, while the cleaning brush 4 cleans the bottom of the pool after being impacted by the nozzle 10, removing the remaining mud. The resulting sewage spreads upwards and is blocked by the dust baffle 7. The moving water flow impacts the collection device 14, and then the sludge pump 11 is started. The sludge pump 11 generates suction on the first extraction pipe 12 and the second extraction pipe 13. The collected sewage is then pumped away through the collection device 14 and transported into the telescopic drain pipe 17 and discharged to the outside. This cycle continues until the bottom of the pool is completely cleaned.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
