Detailed Implementation
[0022] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0023] Please see Figures 1 to 3 This embodiment provides a slurry mixing and venting device, which is a sealed cylinder 1. The top of the cylinder 1 is equipped with a mixing motor 2, a vacuum pump 3, and a feed pipe 4, while the bottom of the cylinder 1 is equipped with a discharge pipe 9. An observation window 5 is provided at the top of the cylinder 1, and a camera device 51 is installed outside the observation window 5. An illumination device 52 is also provided, which illuminates the observation window 5 to illuminate the object being filmed by the camera device 51. The top part of the cylinder 1 is a round cover tightly installed on the upper part of the cylinder 1, which can be disassembled and reassembled as needed, facilitating the inspection and maintenance of the internal structure of the cylinder 1.
[0024] A clean water pipe 6 is installed at the top of the cylinder 1, and the clean water pipe 6 is connected to a liquid meter (not shown in the figure) for measuring the liquid flowing through the clean water pipe 6. A sewage pipe 8 is installed at the bottom of the cylinder 1. The cleaning water for the slurry mixing and exhaust device is introduced into the cavity of the cylinder 1 through the clean water pipe 6. After being stirred and cleaned by the agitator 7, the sewage is discharged from the sewage pipe 8. The sewage pipe 8 and the discharge pipe 9 are respectively connected to hydraulic pump station 10 and hydraulic pump station 21, which control the liquid flow out of the sewage pipe 8 and the discharge pipe 9. In addition, valves are installed on the feed pipe 4, clean water pipe 6, sewage pipe 8 and discharge pipe 9 for closing or opening each pipe.
[0025] The slurry mixing and venting device provided in this embodiment is connected to a remote client. The camera device 51 transmits the captured images to the client. The user can observe the mixing status of the slurry in the cylinder 1 through the client. The user can also remotely control the working status of components such as the mixing motor 2, vacuum pump 3, hydraulic pump station 10 and hydraulic pump station 2 11, and liquid meter through the client.
[0026] Please combine Figure 4 A stirring motor 2 is connected to a stirrer 7 inside the cylinder 1. The stirrer 7 has a rotating base 71, which is driven to rotate by the stirring motor 2. The rotating shaft of the rotating base 71 coincides with the rotating shaft of the cylindrical cylinder 1. Multiple stirring arms 72 of varying lengths are arranged on the rotating base 7 along the radius of the circular cross-section of the cylinder 1. A side wall scraper 74 is provided at the end of each stirring arm 72. In this embodiment, the length of the longest stirring arm 72 is approximately equal to the radius of the circular cross-section of the cylinder 1. A side wall scraper 74 is fixed at the end of the longest stirring arm 72. The side wall scraper 74 is elongated and its length is approximately equal to the height of the side wall of the cylinder 1. One side of the elongated side wall scraper 74 is close to the inner side wall of the cylinder 1. In other embodiments, two or more stirring arms with a length approximately equal to the radius of the cross-section of the cylinder 1 may be provided, and a side wall scraper may be fixed at the end of each stirring arm. This invention does not limit the scope of the invention.
[0027] A stirring rod 73 is also provided at the end of the stirring arm 72. The stirring rod 73 is arranged along the height direction of the cylinder 1, that is, the length of the stirring rod 73 extends from the top to the bottom of the cylinder 1. Multiple stirring blades 75 are provided on the stirring rod 73, and a bottom wall scraper 76 is installed at the end of the stirring rod 73. The bottom wall scraper 76 is elongated, with one side of its length close to the inner wall of the bottom surface of the cylinder 1. Unlike the design of the side wall scraper 74, a bottom wall scraper 76 is installed at the end of each stirring rod 73. Multiple stirring arms 72 of different lengths correspond to the bottom wall scrapers 76 of the stirring rods 73. The scraping area when they rotate can completely cover the bottom surface of the cylinder 1 to achieve a uniform mixing effect of the slurry.
[0028] In this embodiment, the connections between the rotating base 71 and the stirring arm 72, between the stirring arm 72 and the stirring rod 73 and the side wall scraper 74, and between the stirring rod 73 and the bottom wall scraper 76 are fixed by screws. In other embodiments, an integral casting or other fixing connection method may be used, which is not limited by this utility model.
[0029] The working process of the slurry mixing and venting device provided by this utility model is as follows.
[0030] The coarsely mixed slurry is fed into the cylinder 1 through the feed pipe 4. After reaching the designated input volume, the feed pipe 4 is closed. The mixing motor 2 starts mixing, and the vacuum pump 3 continuously or intermittently evacuates the cylinder 1. The user observes the state of the slurry inside the cylinder 1 through the client. When mixing is complete, the discharge pipe 9 is opened to discharge the slurry. When it is necessary to clean the slurry mixing and exhaust device, clean water is introduced into the cylinder 1 through the clean water pipe 6. The mixing motor 2 mixes and cleans at a specified time, and the wastewater after cleaning is discharged through the drain pipe 8.
[0031] When it is found through the observation window 5 that the stirring arm 72, stirring rod 73, side wall scraper 74 or bottom wall scraper 76 is damaged and needs to be replaced, remove the top round cover of the cylinder 1, enter the cylinder 1, and replace the individual parts by disassembling them with screws.
[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
