DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described below in conjunction with the accompanying drawings. Example

[0023] A sewage treatment device for rapid disinfection, such as Figure 1-Figure 2As shown, it includes a tank body 1, a feed pipe is embedded in the eccentric position of the top of the tank body 1, a discharge pipe is embedded in the lower side of the tank body 1, solenoid valves are arranged in the feed pipe and the discharge pipe, a leg 2 is arranged on the lower side of the tank body 1, a hollow shaft 3 is rotatably connected to the center of the top of the tank body 1, a rotating rod 4 is rotatably connected in the hollow shaft 3, a driving member 6 (the driving member 6 adopts a servo motor) is installed at the eccentric position of the top of the tank body 1 through a fixing frame 5, the driving member 6 and the hollow shaft 3 and the rotating rod 4 are driven by a bevel gear set, the hollow shaft 3 and the rotating rod 4 rotate in opposite directions, and the lower end of the hollow shaft 3 is fixedly connected with a first gear for stirring sewage in the tank body 1. A fan blade 7, the lower end of the rotating rod 4 is fixedly connected with a second fan blade 8 for stirring the sewage in the tank body 1, the first fan blade 7 and the second fan blade 8 have opposite inclination directions, and the first fan blade 7 and the second fan blade 8 rotate in opposite directions, so that the sewage flow directions on the upper and lower sides of the tank body 1 are divided into clockwise flow and counterclockwise flow, so that the sewage on the upper and lower sides of the tank body 1 are mixed, and the hollow shaft 3 is fixedly connected with a scraper 9 through a connecting rod. The scraper 9 is made of a smooth material. The scraper 9 is mainly used to scrape impurities adhered to the inner wall of the tank body 1 to prevent adhesion. The bottom end of the tank body 1 is connected with a gas storage tank 10, and a one-way valve is embedded in the bottom of the gas storage tank 10 The top of the gas storage tank 10 is connected with an injection pipe 11, and the injection pipe 11 is connected with nozzles 12 distributed at equal intervals. The injection ports of the nozzles 12 distributed at equal intervals are set to be one-way, which is used for one-way outflow of air to prevent backflow. A piston 13 is connected to the gas storage tank 10 in a limited sliding manner. The piston 13 is provided with three one-way valves distributed at equal intervals in the circumferential direction. The piston 13 moves downward to transfer the gas on the lower side to the upper side. The piston 13 moves upward to discharge the gas on the upper side through the injection pipe 11 and the nozzle 12. The discharged gas cooperates with the sewage to form bubbles. Because the bubbles have buoyancy, they will float upward. During the upward floating process, the bubbles carry the chemical on the lower side. The chemical drugs are flipped upward, so as to achieve the purpose of fully mixing the chemical drugs with the sewage and accelerate the effect of sewage disinfection. The piston 13 is connected to the reciprocating screw 14 when it is rotated. The lower end of the rotating rod 4 is fixedly connected to the reciprocating threaded tube 15. The upper end of the reciprocating screw 14 passes through the jet pipe 11 and is located in the reciprocating threaded tube 15. The reciprocating screw 14 is threadedly matched with the reciprocating threaded tube 15. The driving member 6 drives the rotating rod 4 through the bevel gear set to drive the reciprocating threaded tube 15 to rotate. The rotation of the reciprocating threaded tube 15 cooperates with the reciprocating screw 14 to make it move up and down, and drive the piston 13 to move up and down to inject gas mixed materials into the tank body 1.

[0024] When quickly disinfecting sewage, the operator opens the solenoid valve of the feed pipe, and adds sewage into the tank body 1 through the feed pipe, and starts the driving member 6. The driving member 6 rotates the hollow shaft 3 clockwise and the rotating rod 4 counterclockwise through the bevel gear set. The clockwise rotation of the hollow shaft 3 causes the first blade 7 to rotate clockwise, and the counterclockwise rotation of the rotating rod 4 drives the second blade 8 to rotate counterclockwise. The clockwise rotation of the first blade 7 and the counterclockwise rotation of the second blade 8 cooperate to make the sewage on the upper and lower sides of the tank body 1 flush and mix, so as to avoid the sewage rotating in only a single direction, resulting in some chemicals being unable to fully merge with the sewage. The rotation of the hollow shaft 3 causes the scraper 9 to move circumferentially through the connecting rod, and the scraper The plate 9 moves circumferentially to scrape impurities adhered to the inner wall of the tank body 1, and the rotation of the rotating rod 4 drives the reciprocating threaded tube 15 to rotate. The rotation of the reciprocating threaded tube 15 cooperates with the thread of the reciprocating screw rod 14 to move the piston 13 downward and upward. The piston 13 moves downward to move the gas in the gas storage tank 10 on the lower side into the upper side of the piston 13. The piston 13 moves upward to discharge the gas on the upper side through the nozzle 12 on the jet pipe 11. The gas discharged from the nozzle 12 cooperates with the sewage in the tank body 1 to form bubbles of the discharged gas. Because the bubbles have a certain buoyancy, the bubbles will float upward, thereby achieving the purpose of flipping the chemicals upward, avoiding the accumulation of chemicals on the lower side and affecting the mixing with the sewage, thereby accelerating the sewage disinfection efficiency. Example

[0025] On the basis of Example 1, Figure 2-Figure 5 As shown, it also includes a feeding tank 16, which is embedded in the upper side of the side wall of the tank body 1, and the feeding tank 16 is located on the upper side of the scraper 9. The upper right side of the feeding tank 16 is connected to a discharge frame 17, and a push plate 18 is slidably connected inside the feeding tank 16. The discharge frame 17 is fixedly connected to an electric push rod 19 through a connecting piece. The telescopic end of the electric push rod 19 passes through the feeding tank 16 and is fixedly connected to the push plate 18. The feeding tank 16 is provided with a discharge trough located on the inner side of the tank body 1, and an electric swing frame 20 that cooperates with the discharge trough is installed on the left wall inside the feeding tank 16. The swing rod of the electric swing frame 20 is arranged in an arc structure for swinging chemicals out through the discharge trough.

[0026] The quantitative frame 21 is also included, and the quantitative frame 21 is rotatably connected to the unloading frame 17 through the shaft rod. The lower part of the quantitative frame 21 is provided with a quantitative groove. The left end of the shaft rod is fixedly connected with a spur gear 22 (the spur gear 22 is set as a one-way gear). The right diameter of the feeding tank 16 is smaller than the left diameter thereof. The cross section of the inner wall of the feeding tank 16 is arranged in a stepped manner. The left side of the feeding tank 16 is rotatably connected with an annular shield plate 23. The inner diameter of the annular shield plate 23 is equal to the right diameter of the feeding tank 16, and the inner annular surface of the annular shield plate 23 is smoothly connected with the right side of the feeding tank 16. The annular shield plate 23 is provided with a discharge groove. The outer ring surface of the annular baffle 23 is fixedly connected with an arcuate rack 24 which is slidably connected to the feeding tank 16. The number of teeth of the spur gear 22 is a multiple of the number of teeth of the arcuate rack 24 (the ratio is 1:0.5). The arcuate rack 24 is meshed with the spur gear 22. The outer ring surface of the annular baffle 23 is provided with a track groove 25. The track groove 25 surrounds the annular baffle 23 by 180° and is located at the rear of the annular baffle 23. The lower side of the right side surface of the push plate 18 is fixedly connected with a movable frame 26 which is limitedly slidably connected to the feeding tank 16. The movable frame 26 is fixedly connected with a guide block 27 which is slidably matched with the track groove 25.

[0027] The chemicals to be added are poured into the unloading frame 17, and then the operator starts the electric swing frame 20 and the electric push rod 19 to work. The electric push rod 19 works to push the push plate 18 to move left. The push plate 18 moves left and drives the guide block 27 to move left through the moving frame 26. The guide block 27 moves left and cooperates with the track groove 25 to make the annular shield plate 23 rotate 180° forward in the circumferential direction, so that the discharge port on the annular shield plate 23 coincides with the discharge slot on the feeding tank 16. The push plate 18 Move leftward to push the chemicals to the left, and cooperate with the electric swing frame 20 to swing the chemicals into the tank body 1 through the discharge port and the discharge chute, and the annular shield 23 rotates forward 180° to make the arc rack 24 move 180° circumferentially (in this process, the arc rack 24 rotates circumferentially to mesh with the spur gear 22, and the arc rack 24 continues to move circumferentially to mesh with the spur gear 22 to rotate. The rotation of the spur gear 22 can rotate the quantitative frame 21 through the shaft. When the arc rack 24 rotates 180° circumferentially , at this time, the quantitative frame 21 rotates 180°, so that the quantitative slot on the quantitative frame 21 rotates to the upper side, and the chemicals in the unloading frame 17 fall downward into the quantitative slot of the quantitative frame 21). When the electric push rod 19 moves the push plate 18 to the right, the annular shield 23 rotates backward 180° to drive the arc-shaped rack 24 thereon to move circumferentially. The annular shield 23 rotates backward to misalign the discharge port thereon with the discharge slot to avoid that when no chemicals are thrown out, the discharge slot is in an open state, and part of the sewage enters the feeding tank 16 when the sewage is mixed, thereby causing the powdered chemicals in the feeding tank 16 to agglomerate, affecting the effect of sewage disinfection. At this time, the arc-shaped rack 24 moves circumferentially to drive the spur gear 22 to rotate, and the spur gear 22 rotates to drive the quantitative frame 21 to make the chemicals in the quantitative slot on it move circumferentially 180° and enter the feeding tank 16. At this time, the push plate 18 is located on the right side of the quantitative frame 21, and the push plate 18 moves to the left again to achieve the addition of chemicals into the tank body 1.

[0028] On the basis of the above, the electric swing frame 20 works to swing the swing frame on it toward the chemicals. During the process of swinging the chemicals outward, the first fan blade 7 rotates to make the sewage on the upper side of the tank body 1 flow. The chemicals thrown outward encounter the flowing sewage, which can promote the rapid mixing of the chemicals and the sewage, avoiding the powdered chemicals from being directly sprinkled into the sewage, causing some powdered chemicals to agglomerate, and the chemicals being thrown out will scatter everywhere, preventing the chemicals from piling up.
