Description

Technical Field

[0001] This application relates to the field of concrete mixing equipment cleaning technology, and in particular to a rapid cleaning device for concrete mixing tanks. Background Technology

[0002] In fields such as building construction, road construction, and precast component production, concrete mixing tanks serve as core equipment, undertaking the task of mixing and preparing concrete raw materials.

[0003] Concrete has high viscosity and easy curing properties. After the mixing operation is completed, a large amount of concrete slurry is often left on the inner wall of the tank, the mixing blades and the bottom. Traditional cleaning methods usually involve high-pressure water gun washing and manual removal, but these are inefficient and the concrete residue on the inner wall of the mixing tank is difficult to clean thoroughly.

[0004] Therefore, this application provides a rapid cleaning device for concrete mixing tanks. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a rapid cleaning device for concrete mixing tanks, which overcomes the deficiencies of existing technologies. It aims to solve the problem that concrete has high viscosity and easy curing characteristics, and after the mixing operation is completed, a large amount of concrete slurry often remains on the inner wall of the tank, the mixing blades and the bottom. Traditional cleaning methods usually involve high-pressure water gun washing and manual removal, but these are inefficient and the concrete residue on the inner wall of the mixing tank is difficult to clean thoroughly.

[0006] To achieve the above objectives, this application provides the following technical solution: It includes a mixing tank body, an internal mixing mechanism, a ring-shaped spraying mechanism on one side of the mixing tank body, an angle adjustment mechanism on the top side of the ring-shaped spraying mechanism, and a ring-shaped main pipe fixedly installed on one side of the mixing tank body. Several sets of vertical plates are fixedly installed on one side of the ring-shaped main pipe, and nozzles are hinged to one side of each vertical plate. Flexible hoses are installed between each set of nozzles and the ring-shaped main pipe. A scraping mechanism is internally installed in the mixing tank body. The scraping mechanism includes a motor bracket fixedly installed at the bottom of the mixing tank body. A motor is fixedly installed in the middle of the motor bracket. A scraper blade (first scraper) is fixedly installed through the output end of the motor on one side of the mixing tank body, and scraper blades (second scraper) are fixedly installed at both ends of the first scraper.

[0007] By adopting the above technical solution, when cleaning the interior of the mixing tank after the operation is completed, several sets of nozzles are activated. The nozzles spray high-pressure water at a certain angle to impact the residual concrete on the inner wall of the mixing tank. At the same time, the motor drives scraper one and scraper two to rotate, and scraper one and scraper two scrape away the stubborn residue on the inner wall of the mixing tank. The angle of the annular spray mechanism can be adjusted by the angle adjustment mechanism, which is conducive to the all-round cleaning of the interior of the mixing tank, resulting in a more thorough cleaning effect and extending the service life of the mixing tank. At the same time, the scraping mechanism and the annular spray mechanism work synchronously, and the combination of physical scraping and high-pressure washing helps to shorten the cleaning time and improve the cleaning efficiency.

[0008] As a preferred technical solution of this application, the angle adjustment mechanism includes a disc, which is fixedly installed on the inner ring of the annular main pipe. Several sets of internal threaded sleeves are fixedly installed inside the disc. Each set of internal threaded sleeves is threadedly connected to a screw. Each set of screws corresponds to a nozzle. One end of each screw is rotatably connected to a fixed shaft. One end of each nozzle is fixedly installed with two sets of connecting brackets. The fixed shaft is rotatably connected between the corresponding two sets of connecting brackets.

[0009] By adopting the above technical solution, the vertical displacement of the screw is adjusted by rotating the screw. Since the screw is hinged between the two sets of connecting frames through a fixed shaft, the screw drives the nozzle to adjust the angle around the bottom of the vertical plate, thereby changing the pitch angle of the nozzle and improving the flexibility of the nozzle when impacting the inner wall of the mixing tank.

[0010] As a preferred technical solution of this application, an inlet pipe is fixedly installed on one side of the annular main pipeline.

[0011] By adopting the above technical solution, the water inlet pipe facilitates the connection between the ring main pipe and the water outlet mechanism, thus improving its practicality during use.

[0012] As a preferred technical solution of this application, a support frame is fixedly installed at the bottom of the mixing tank body, a sedimentation tank is fixedly installed at the bottom of the support frame, and a discharge pump is fixedly installed at the top of the sedimentation tank on one side of the support frame. The discharge pump is connected to both the mixing tank body and the sedimentation tank by a connecting pipe.

[0013] By adopting the above technical solution, the cleaning wastewater in the mixing tank is transported to the sedimentation tank through the connecting pipe by starting the discharge pump, thereby achieving the purpose of automatic discharge and unified collection of the cleaning wastewater in the mixing tank.

[0014] As a preferred technical solution of this application, a filter plate is fixedly installed inside the sedimentation tank, a circulating water pump is placed on one side of the sedimentation tank, the extraction end of the circulating water pump is connected to the bottom of the sedimentation tank, and a water pipe is connected between the circulating water pump and the water inlet pipe.

[0015] By adopting the above technical solution, the cleaning wastewater entering the sedimentation tank is filtered through the filter plate, and the circulating water pump draws the clear water from the bottom of the sedimentation tank and transports it to the ring main pipeline through the water pipe and the inlet pipe, thereby improving the water resource utilization rate and reducing water waste.

[0016] As a preferred technical solution of this application, a second discharge pump is placed on the side of the sedimentation tank away from the circulating water pump. A discharge pipe is connected between the extraction end of the second discharge pump and the sedimentation tank, and the extraction end of the discharge pipe is located above the filter plate.

[0017] By adopting the above technical solution, by starting the second discharge pump, the impurities above the filter plate in the sedimentation tank are discharged through the discharge pipe, which helps to maintain the filtration effect of the filter plate.

[0018] As a preferred technical solution of this application, a filter is installed at the connection between the water inlet pipe and the water pipe.

[0019] By adopting the above technical solution, impurities in the water entering the annular main pipe are further purified by the filter, which effectively reduces the possibility of nozzle clogging and reduces the number of maintenance operations.

[0020] As a preferred technical solution of this application, the filter plate is inclined, and the lower inclined end of the filter plate is close to the discharge pipe.

[0021] By adopting the above technical solution, and by setting the filter plate at an angle, it is beneficial for impurities above the filter plate to slide down to the extraction end of the discharge pipe under the action of gravity, thereby improving the discharge effect of impurities above the filter plate.

[0022] The beneficial effects of this application are: 1. When cleaning the interior of the mixing tank after the main body operation is completed, several sets of spray nozzles are activated. The nozzles spray high-pressure water at a certain angle to impact the residual concrete on the inner wall of the mixing tank. At the same time, the motor drives scraper one and scraper two to rotate, scraping away stubborn residues on the inner wall of the mixing tank. The angle of the annular spray mechanism can be adjusted by the angle adjustment mechanism, which is conducive to comprehensive cleaning of the interior of the mixing tank, resulting in a more thorough cleaning effect and extending the service life of the mixing tank. In addition, the scraping mechanism and the annular spray mechanism work in sync, combining physical scraping with high-pressure washing, which helps to shorten the cleaning time and improve the cleaning efficiency.

[0023] 2. The vertical displacement of the screw is adjusted by rotating the screw. Since the screw is hinged between the two sets of connecting frames through a fixed shaft, the screw drives the nozzle to adjust the angle around the bottom of the vertical plate, thereby changing the pitch angle of the nozzle and improving the flexibility of the nozzle when impacting the inner wall of the mixing tank.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Reference Figure 1-4A rapid cleaning device for concrete mixing tanks includes a mixing tank body 1, an internal mixing mechanism 101, and a ring-shaped spraying mechanism 2 on one side of the mixing tank body 1. The top of the ring-shaped spraying mechanism 2 has an angle adjustment mechanism 5. The ring-shaped spraying mechanism 2 includes a ring-shaped main pipe 201, which is fixedly installed on one side of the mixing tank body 1. Several sets of vertical plates 202 are fixedly installed on one side of the ring-shaped main pipe 201, and spray nozzles 203 are hinged to one side of each vertical plate 202. 03 is connected to the annular main pipe 201 by a flexible hose 204. The inside of the mixing tank body 1 is equipped with a scraping mechanism 4. The scraping mechanism 4 includes a motor bracket 401, which is fixedly installed at the bottom of the mixing tank body 1. A motor 402 is fixedly installed in the middle of the motor bracket 401. A scraper 403 is fixedly installed on one side of the output end of the motor 402 through the mixing tank body 1. A scraper 404 is fixedly installed at both ends of the scraper 403. A water inlet pipe 12 is fixedly installed on one side of the annular main pipe 201.

[0028] When cleaning the interior of the mixing tank 1 after the operation is completed, several sets of spray nozzles 203 are activated. The nozzles spray high-pressure water at a certain angle to impact the residual concrete on the inner wall of the mixing tank 1. At the same time, the motor 402 drives the scraper 1 403 and scraper 2 404 to rotate. The scraper 1 403 and scraper 2 404 scrape away the stubborn residue on the inner wall of the mixing tank 1. The angle adjustment mechanism 5 adjusts the angle of the annular spray mechanism 2, which is conducive to the all-round cleaning of the interior of the mixing tank 1, the cleaning effect is more thorough, and the service life of the mixing tank 1 is extended. At the same time, the scraping mechanism 4 and the annular spray mechanism 2 work synchronously, and the combination of physical scraping and high-pressure flushing helps to shorten the cleaning time and improve the cleaning efficiency. The water inlet pipe 12 facilitates the connection between the annular main pipe 201 and the water outlet mechanism, which improves the practicality during use.

[0029] Reference Figure 2-4 The angle adjustment mechanism 5 includes a disc 501, which is fixedly installed on the inner ring of the annular main pipe 201. Several sets of internal threaded sleeves 502 are fixedly installed inside the disc 501. Each set of internal threaded sleeves 502 is threadedly connected to a screw 503. Each set of screws 503 corresponds to a nozzle 203. One end of the screw 503 is rotatably connected to a fixed shaft 504. One end of the nozzle 203 is fixedly installed with two sets of connecting frames 505. The fixed shaft 504 is rotatably connected between the two sets of connecting frames 505. A support frame 3 is fixedly installed at the bottom of the mixing tank body 1. A sedimentation tank 6 is fixedly installed at the bottom of the support frame 3. A discharge pump 7 is fixedly installed at the top of the sedimentation tank 6 on one side of the support frame 3. A connecting pipe 8 connects the discharge pump 7 to both the mixing tank body 1 and the sedimentation tank 6. The vertical displacement of the screw 503 is adjusted by rotating the screw 503. Since the screw 503 is hinged between the two sets of connecting frames 505 through the fixed shaft 504, the screw 503 drives the nozzle 203 to adjust its angle around the bottom of the vertical plate 202, thereby changing the pitch angle of the nozzle 203 and improving the flexibility of the nozzle 203 when impacting the inner wall of the mixing tank body 1. By starting the discharge pump 7, the cleaning wastewater in the mixing tank body 1 is transported to the sedimentation tank 6 through the connecting pipe 8, so as to achieve the purpose of automatic discharge and unified collection of the cleaning wastewater in the mixing tank body 1.

[0030] Reference Figure 1-3 A filter plate 9 is fixedly installed inside the sedimentation tank 6. A circulating water pump 10 is placed on one side of the sedimentation tank 6. The extraction end of the circulating water pump 10 is connected to the bottom of the sedimentation tank 6. A water pipe 11 connects the circulating water pump 10 and the inlet pipe 12. A filter 15 is installed at the connection between the inlet pipe 12 and the water pipe 11. The cleaning wastewater entering the sedimentation tank 6 is filtered by the filter plate 9. The circulating water pump 10 draws the clear water from the lower layer of the sedimentation tank 6 and transports it to the annular main pipe 201 through the water pipe 11 and the inlet pipe 12, thereby improving the water resource utilization rate and reducing water waste. The filter 15 further purifies the impurities in the water entering the annular main pipe 201, effectively reducing the possibility of the nozzle 203 being blocked and reducing the number of maintenance times.

[0031] Reference Figure 1-3 A discharge pump 2 13 is placed on the side of the sedimentation tank 6 away from the circulating water pump 10. The extraction end of the discharge pump 2 13 is connected to the sedimentation tank 6 by a discharge pipe 14. The extraction end of the discharge pipe 14 is located above the filter plate 9. The filter plate 9 is inclined, and the lower inclined end of the filter plate 9 is close to the discharge pipe 14. By starting the discharge pump 2 13, the discharge pump 2 13 discharges the impurities above the filter plate 9 in the sedimentation tank 6 through the discharge pipe 14, which helps to maintain the filtration effect of the filter plate 9. Because the filter plate 9 is inclined, the impurities above the filter plate 9 can slide down to the extraction end of the discharge pipe 14 under the action of gravity, which improves the discharge effect of the impurities above the filter plate 9.

[0032] Working principle: After the mixing tank body 1 is completed, when cleaning its interior, several sets of nozzles 203 are activated. The nozzles spray high-pressure water at a certain angle to impact the residual concrete on the inner wall of the mixing tank body 1. At the same time, the motor 402 drives the scraper 1 403 and scraper 2 404 to rotate. The scraper 1 403 and scraper 2 404 scrape away the stubborn residue on the inner wall of the mixing tank body 1. The angle of the annular spraying mechanism 2 is adjusted by the angle adjustment mechanism 5. The vertical displacement of the screw 503 is adjusted by rotating the screw 503. Since the screw 503 is hinged between the two sets of connecting frames 505 through the fixed shaft 504, the screw 503 drives the nozzle 203 to adjust the angle around the bottom of the vertical plate 202, thereby changing the pitch angle of the nozzle 203.
