DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] As Figure 1 , Figure 2 and Figure 3 shown, a mobile sewage treatment device includes a mobile base 1. In the middle of the upper end of the mobile base 1, a treatment tank 4 penetrating the top of the mobile base 1 is fixedly installed. In the middle of the inner wall of the treatment tank 4, a filtering and cleaning assembly 2 is fixedly installed. At the bottom of the filtering and cleaning assembly 2, a drug mixing and treatment assembly 3 is movably connected.

[0026] When sewage enters the treatment tank 4, the filtering and cleaning assembly 2 can intercept and filter impurities in the sewage. Subsequently, when the sewage is stirred and mixed with the medicine at the bottom of the treatment tank 4, the scraper 25 rotates synchronously to scrape the dirt on the surface of the conical filter screen 22 and push it into the discharge cylinder 26. The screw conveyor mechanism 27 can quickly discharge the impurities. Due to the shape characteristics of the conical filter screen 22, the scraper 25 can better push the impurities when rotating, accelerating the slag discharge rate of the device. After the sewage is filtered, the drug mixing and treatment assembly 3 can fully mix the sewage with chemical agents to remove the dissolved pollutants in the sewage. It can achieve different rotation speeds of the scraper 25 and the two rotating shafts 35 through a single power source of the motor 23, enabling the device to stir the mixture evenly at a certain rate while quickly discharging the slag, with high applicability and energy saving and consumption reduction.

[0027] As Figure 3 shown, the filtering and cleaning assembly 2 includes a feed pipe 21. The top of the outer wall of the feed pipe 21 is fixedly connected to the inner wall of the left part of the upper end of the treatment tank 4. In the middle of the inner wall of the treatment tank 4, a conical filter screen 22 is fixedly installed. The bottom of the feed pipe 21 is located above the conical filter screen 22.

[0028] The sewage is introduced into the treatment tank 4 through the feed pipe 21. The feed pipe 21 is located on the right side of the discharge cylinder 26, which can prevent the sewage from flowing into the discharge cylinder 26. The conical filter screen 22 filters the insoluble impurities inside when the sewage falls under the action of gravity.

[0029] As Figure 3 shown, mounting frames are fixedly installed at the front and rear positions in the middle of the upper end of the treatment tank 4. At the upper end of the mounting frames, a motor 23 is fixedly installed. In the middle of the upper end of the treatment tank 4, a driving shaft 24 penetrating the top of the treatment tank 4 is rotatably connected. The output end of the motor 23 penetrates the top of the mounting frames and is fixedly connected to the upper end of the driving shaft 24. In the middle of the outer wall of the driving shaft 24, a scraper 25 is fixedly installed. The lower end of the scraper 25 is lapped with the outer surface of the conical filter screen 22.

[0030] The output end of the motor 23 can drive the drive shaft 24 to rotate. The drive shaft 24 can drive the scraper 25 to rotate on the surface of the conical filter screen 22. Since the surface of the conical filter screen 22 is inclined, the scraper 25 can better drive impurities and dirt into the discharge cylinder 26 when rotating.

[0031] As Figure 3 and Figure 4 As shown, a discharge cylinder 26 is fixedly installed at the middle position of the left part of the outer wall of the treatment tank 4. The discharge cylinder 26 is communicated with the treatment tank 4. A screw conveyor mechanism 27 is movably connected to the inner cavity of the discharge cylinder 26. A discharge frame 28 is communicated and arranged at the left part of the bottom of the outer wall of the discharge cylinder 26.

[0032] The screw conveyor mechanism 27 is an existing mechanism, which includes a motor, a connecting shaft and a plurality of spiral auger blades. When the motor drives the connecting shaft to rotate, the plurality of screw auger blades can convey the impurities to the left and then discharge them through the discharge frame 28.

[0033] As Figure 4 and Figure 5 As shown, the drug mixing and treatment assembly 3 includes a protective cover 31. A top plate 32 is fixedly installed at the top of the inner wall of the protective cover 31. Fixing frames 33 are fixedly installed at the left and right parts of the lower end of the top plate 32. One ends of the two fixing frames 33 away from each other are fixedly installed with the left and right parts of the inner wall of the treatment tank 4. The bottom of the outer wall of the drive shaft 24 penetrates through the top of the top plate 32 and is fixedly sleeved with a driving gear 34. The front and rear parts of the lower end of the top plate 32 are rotatably connected with rotating shafts 35. Driving gears 36 are fixedly sleeved on the tops of the outer walls of the two rotating shafts 35. The outer surfaces of the two driving gears 36 are meshed with the outer surface of the driving gear 34.

[0034] The protective cover 31 is of a conical structure to avoid liquid accumulation. When the drive shaft 24 rotates, the driving gear 34 rotates accordingly. The two driving gears 36 rotate synchronously by meshing with the driving gear 34. Among them, the number of teeth of the driving gear 34 is less than the number of teeth of the two driving gears 36, so that when the driving gear 34 rotates, the rotation speeds of the two rotating shafts 35 are lower than the rotation speed of the drive shaft 24.

[0035] As Figure 3 and Figure 5 As shown, a plurality of stirring rods 37 arranged linearly are fixedly installed at the bottoms of the outer walls of the two rotating shafts 35. A medicine inlet pipe 38 is fixedly installed at the bottom position of the right part of the outer wall of the treatment tank 4.

[0036] Through the rotation of two rotating shafts 35, a number of stirring rods 37 mix the sewage and chemical agents evenly. Among them, the rotational speeds of the drive shaft 24 and the two rotating shafts 35 are different, so that when the scraper 25 cleans the conical filter screen 22, a number of stirring rods 37 can stir the mixture at an appropriate rate, with strong applicability. Among them, the chemical agent inlet pipe 38 is a pipe that can be freely opened and closed, which communicates with the treatment tank 4 and is used to transport chemical agents.

[0037] As Figure 2 and Figure 6 shown, a drain pipe 39 is fixedly installed at the lower end of the treatment tank 4. An electromagnetic valve is fixedly installed at the bottom of the inner cavity of the drain pipe 39. A filter cylinder 310 is threadedly connected to the bottom inner wall of the drain pipe 39. The outer wall of the filter cylinder 310 is a filter screen structure all around.

[0038] The bottom of the treatment tank 4 is conical to prevent liquid accumulation. After sewage treatment, it is discharged through the drain pipe 39, and the sediment generated after the reaction of sewage and chemical agents is intercepted by the filter cylinder 310. Among them, the electromagnetic valve can realize the free opening and closing of the drain pipe 39.

[0039] The working principle of the present utility model: Sewage is introduced into the treatment tank 4 through the feed pipe 21, and the conical filter screen 22 filters the insoluble impurities inside when the sewage falls under the action of gravity.

[0040] An appropriate amount of chemical agent is added through the chemical agent inlet pipe 38. The motor 23 is started, and its output end drives the drive shaft 24 to rotate. The drive shaft 24 can drive the scraper 25 to rotate on the surface of the conical filter screen 22. When the scraper 25 rotates, it can drive impurities and dirt into the discharge cylinder 26, and the screw conveyor mechanism in the discharge cylinder 26 conveys and discharges the residue. At the same time, the drive shaft 24 drives the driving gear 34 to rotate, and two reduction gears 36 drive the two rotating shafts 35 to rotate synchronously by meshing with the driving gear 34. The rotational speeds of the drive shaft 24 and the two rotating shafts 35 are different, so that when the scraper 25 cleans the conical filter screen 22, a number of stirring rods 37 can stir the mixture at an appropriate rate, with strong applicability.

[0041] The treated sewage can be discharged through the drain pipe 39 by opening the electromagnetic valve. The filter cylinder 310 intercepts the sediment generated after the reaction of sewage and chemical agents. Subsequently, when cleaning the filter cylinder 310, it only needs to be unscrewed.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model.
