[0020] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.
[0021] like Figure 1-Figure 4 The temperature-controlled sludge fermentation raw material water spraying mechanism of the utility model shown in the figure comprises a frame 13 and a conveyor belt 14 arranged on the frame 13, a hopper 5 located directly above the conveyor belt 14 is arranged on the frame 13, a feed port 4 of the hopper 5 faces the conveyor belt 14, a mixing drum is arranged on one side of the output end of the conveyor belt 14, and a temperature-controlled water spraying device is arranged above the mixing drum.
[0022] Two positioning plates 15 are provided between the hopper 5 and the conveyor belt 14. The two positioning plates 15 are respectively located on the left and right sides of the drop port 4, and the upper end faces of the positioning plates 15 are fixedly connected to the lower end faces of the hopper 5, and the lower end faces of the positioning plates 15 are fitted with the upper end faces of the conveyor belt 14. The positioning plates 15 extend laterally along the length direction of the conveyor belt 14 and are aligned with the end portions of the conveyor belt 14. The lateral distance between the two positioning plates 15 forms a dried sludge feeding space. The dried sludge feeding space formed by the lateral distance between the two positioning plates 15 can prevent the dried sludge from falling from the left and right sides of the conveyor belt 14 during the transportation process of the conveyor belt 14. By providing a connecting rod 3 fixedly connected to the left and right side walls of the hopper 5 on the frame 13, and fixing a cross bar 6 on the end of the connecting rod 3, the upper end surface of the positioning plate 15 is fitted with the lower end surface of the cross bar 6, and the hopper 5 is installed on the frame 13 through the connecting rod 3. By utilizing the connecting rod 3 and the cross bar 6, the stability of the hopper 5 and the frame 13 during use can be improved. The mixing drum includes a U-shaped groove plate 16 extending laterally in the left and right directions of the conveyor belt 14, and the opening of the U-shaped groove plate 16 faces upward, partitions 10 are fixedly connected to the left and right end surfaces of the U-shaped groove plate 16, and a rotating rod 18 rotatably connected to the two partitions 10 is arranged in the U-shaped groove plate 16, and a spiral fan blade 17 is fixedly connected to the outer wall of the rotating rod 18, and a driving device 11 for driving the rotating rod 18 to rotate is also arranged on the side of one of the partitions 10 away from the U-shaped groove plate 16. The spiral fan blade 17 fixed to the rotating rod 18 is driven by the driving device 11 to rotate, so that it can stir the dried sludge in the U-shaped groove plate 16 and fully mix it with water at a suitable temperature, fermentation bacteria and nutrients. The temperature-controlled water spraying device includes a water tank 1 and a water outlet pipe 7 connected to the inside of the water tank 1, and a connecting pipe 8 is arranged on the outer wall of the water outlet pipe 7, and a nozzle 9 is connected to the end of the connecting pipe 8 away from the water outlet pipe 7. A heating mechanism 22 and a first temperature sensor 21 are also arranged in the water tank 1, and a water pump 2 is arranged on the outer wall of the connecting pipe 8. The first temperature sensor 21 is electrically connected to the heating mechanism 22. When the first temperature sensor 21 senses that the water in the water tank 1 is lower than a predetermined temperature, it will send an electrical signal to the heating mechanism 22 to control the heating mechanism 22 to heat the water in the water tank 1. When it reaches an appropriate temperature, the first temperature sensor 21 will send an electrical signal to the heating mechanism 22 to control the heating mechanism 22 to stop heating the water in the water tank 1, so that the water in the water tank 1 always maintains an appropriate temperature, and then the water in the water tank 1 is sprayed out from the nozzle 9 through the water outlet pipe 7 and the connecting pipe 8 by turning on the water pump 2 to water the dried sludge in the mixing drum.By further arranging a plurality of rollers 20 on the frame 13, the plurality of rollers 20 are equidistantly distributed along the length extension direction of the conveyor belt 14 and supported on the lower end surface of the upper belt of the conveyor belt 14, and the length extension direction of the rollers 20 is consistent with the left and right extension direction of the conveyor belt 14, the upper belt of the conveyor belt 14 is supported by the rollers 20, so that the stability of the conveyor belt 14 during use can be improved, and it can be prevented from being greatly depressed downward due to excessive weight of the dried sludge, so that the dried sludge falls out of the outside of the conveyor belt 14. By arranging a second temperature sensor 19 in the U-shaped groove plate 16, and arranging a display 12 electrically connected to the second temperature sensor 19 on the frame 13, the temperature of the dried sludge in the mixing drum can be monitored by the display 12 and the second temperature sensor 19.
[0023] Combined with Figure 1-4 It can be seen that the method of using the utility model is as follows: first, by starting the conveyor belt 14, the conveyor belt 14 is rotated, and the dried sludge falling from the drop hole of the hopper 5 onto the conveyor belt 14 is driven to move in the dried sludge feeding space, so that a part of it falls from the output end of the conveyor belt 14 into the U-shaped groove plate 16, and then fermentation bacteria and nutrients are added therein. Because the water tank 1 is also provided with a first temperature sensor 21 and a heating mechanism 22, the water in the water tank 1 can be heated to a suitable temperature, so the staff can use the water pump 2 to pump the water in the water tank 1. Water is extracted and sprayed out from the nozzle 9 through the outlet pipe 7 and the connecting pipe 8, so as to inject a large amount of water of suitable temperature into the dried sludge in the U-shaped trough plate 16, and then the driving device 11 drives the rotating rod 18 to rotate, so that the spiral fan blades stir the dried sludge in the U-shaped trough plate 16, so that it is fully mixed with water, fermentation bacteria and nutrients, and the temperature of the mixed dried sludge in the U-shaped trough plate 16 can also reach a suitable temperature, which is convenient for fermentation, and then the mixed dried sludge is transferred to a cement pool, a plastic barrel or a special fermentation tank.
