Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0021] See Figures 1-3 This utility model provides a biomass boiler wastewater treatment device, comprising:

[0022] Wastewater collection mechanism 1 is used to collect and store wastewater. Wastewater collection mechanism 1 is connected to spray gun 4 through conveying pipe 2. Liquid pump is connected to conveying pipe 2. Liquid pump can pressurize the wastewater in conveying pipe 2, so that the wastewater flows from wastewater collection mechanism 1 through conveying pipe 2 and is sprayed out at spray gun 4. Spray gun 4 is connected to incinerator 6. Incinerator can incinerate wastewater.

[0023] The wastewater collection mechanism 1 includes a collection tank 11 and fixed shafts 111. The collection tank 11 is hollow inside and has an opening on its top surface. The collection tank 11 is equipped with a heating component for heating the wastewater. The heating component can prevent the high concentration of organic matter and oily substances contained in the wastewater from condensing. Two fixed shafts 111 are fixedly connected to the top surface of the collection tank 11.

[0024] The movable seat 12 is slidably disposed on the top of the collection pool 11. A threaded shaft 13 is rotatably connected to the top surface of the movable seat 12. The top end of the threaded shaft 13 is rotatably connected to the fixed bracket 121. The fixed bracket 121 is fixedly connected to the movable seat 12. The bottom end of the threaded shaft 13 passes through the movable seat 12 and is connected to the output shaft of the drive component (not shown in the figure). The drive component is fixedly disposed on the bottom surface of the movable seat 12. The drive component can drive the threaded shaft 13 to reciprocate.

[0025] The lifting seat 14 is located above the movable seat 12. The lifting seat 14 is threadedly connected to the threaded shaft 13. When the threaded shaft 13 reciprocates, it can drive the lifting seat 14 to reciprocate up and down relative to the movable seat 12. A plurality of rotating bushings 141 are rotatably mounted on the lifting seat 14. The bottom ends of the rotating bushings 141 all pass through the movable seat 12. A plurality of stirring elements 142 are fixedly connected to the rotating bushings 141 located below the movable seat 12. A plurality of support shafts 122 are fixedly connected to the fixed bracket 121. The support shafts 122 and the rotating bushings 141 are correspondingly matched. The rotating bushings 141 are all sleeved on the outside of the support shafts 122, and the surface of the support shafts 122 is provided with spiral grooves. The rotating bushings 141 are all fixedly provided with guide posts that cooperate with the spiral grooves. When there is relative movement between the lifting seat 14 and the movable seat 12, the plurality of rotating bushings 141 can be raised and lowered while rotating, thereby stirring the wastewater. During the raising and lowering of the lifting seat 14, the rotation direction of the stirring elements 142 is opposite, which can create turbulence in the collection tank 11, further improving its stirring effect.

[0026] Two mating bushings 15 are rotatably connected to the movable seat 12. The mating bushings 15 and the fixed shaft 111 are mated in a one-to-one correspondence. The mating bushings 15 are sleeved on the outside of the fixed shaft 111, and the fixed shaft 111 is provided with a reciprocating helical groove. The mating bushings 15 are provided with protrusions that mate with the reciprocating helical groove. The mating method between the fixed shaft 111 and the mating bushings 15 can be referred to as that of a reciprocating lead screw. That is, under the premise that the rotation direction of the mating bushings 15 remains unchanged, the horizontal reciprocating motion of the movable seat 12 can be realized. Gears 151 are fixedly connected to the bushings 15. A sliding magnet 16 is slidably connected to the side wall of the lifting seat 14 near the gear 151. A double-sided rack 161 is fixedly connected to the sliding magnet 16. Fixed magnets 17 are fixedly connected to the lifting seats 14 on both sides of the sliding magnet 16. The fixed magnets 17 can exert an attractive force on the sliding magnet 16. By adjusting the gap between the two fixed magnets 17 and the magnitude of the magnetic force that can be generated between the fixed magnets 17 and the sliding magnet 16, the sliding magnet 16 can be engaged with only one fixed magnet 17 at any given time. At this time, the other fixed magnet 17 cannot interfere with the sliding magnet 16. When the sliding magnet 16 is engaged with one of the fixed magnets 17, the double-sided rack 161 only meshes with the gear 151 near that fixed magnet 17. Under the magnetic force between the fixed magnets 17 and the sliding magnet 16, the double-sided rack 161 can stably mesh with the gear 151. A toggle element 18 is fixedly connected to the fixed brackets 121 on both sides of the sliding magnet 16. The two toggle elements 18 are respectively set at the top and bottom of the fixed brackets 121. A guide rod that can cooperate with the toggle element 18 is fixedly connected to the sliding magnet 16. Both the guide rod and the toggle element 18 are provided with chamfers that cooperate with each other.

[0027] See Figures 1-3 Preferably, the driving component is a rotary motor, which can provide sufficient power.

[0028] See Figures 1-3 Preferably, a cleaning mechanism 3 is connected to the conveying pipe 2. The cleaning mechanism 3 uses hot water or steam to flush the inner wall of the conveying pipe 2 to prevent scale buildup inside the conveying pipe 2. Flushing the inner wall of the pipe with hot water or steam is a common existing technology, so it will not be described in detail here.

[0029] See Figures 1-3 Preferably, the spray gun 4 is connected to an atomizing mechanism 5, which uses steam as a carrier to atomize the wastewater. Steam helps the wastewater to be atomized better, while preventing the evaporation of grease and oil from the wastewater on the hot and cold contact surfaces and the clogging of the nozzle by suspended matter in the wastewater.

[0030] See Figures 1-3 Preferably, both the fixed magnet 17 and the sliding magnet 16 are permanent magnets.

[0031] See Figures 1-3Preferably, the side wall of the collection pool 11 is provided with a through hole for connection to the conveying pipe 2.

[0032] See Figures 1-3 Preferably, the movable seat 12, fixed shaft 111 and drive components are all located above the wastewater level in the collection tank 11 to prevent organic matter and oil in the wastewater from adhering to the surface of the components and affecting their use. Users can achieve the above functions by installing a liquid level sensor switch inside the collection tank 111. When the liquid level reaches the liquid level sensor switch, the injection of wastewater into the collection tank 11 will stop.

[0033] In the implementation of this utility model: The drive unit is activated, causing the threaded shaft 13 to rotate clockwise. The lifting seat 14 descends relative to the moving seat 12. At this time, the sliding magnet 16 engages with one of the fixed magnets 17. During the descent of the lifting seat 14, several rotating bushings 141 descend synchronously. Under the action of the spiral groove, the rotating bushings 141 drive the stirring element 142 to rotate and descend simultaneously. At the same time, one side of the double-sided rack 161 meshes with the gear 151 near the fixed magnet 17, causing the gear 151 to rotate. Under the action of the reciprocating spiral groove, the moving seat 12... The lifting seat 14 moves horizontally along the fixed shaft 111 for a certain distance. When the lifting seat 14 reaches the bottom of its movement range, the actuating member 18 cooperates with the guide rod to make the sliding magnet 16 move horizontally for a certain distance and cooperate with another fixed magnet 17. At this time, the other side of the double-sided rack 161 meshes with another gear 151. Then the driving member reverses, the lifting seat 14 rises, and drives the mating bushing 15 to rotate. The moving seat 12 continues to move in the original direction. When the moving seat 12 moves to one end of the fixed shaft 111, it can automatically change the movement direction of the moving seat 12 under the action of the reciprocating spiral groove.

[0034] Wastewater in collection tank 11 enters spray gun 4 through conveying pipe 2. After atomization mechanism 5 atomizes the wastewater, incinerator 6 incinerates the wastewater.

[0035] This utility model provides a biomass boiler wastewater treatment device, which has the following beneficial effects:

[0036] 1. It can pressurize and atomize wastewater containing high concentrations of organic matter and oil, and then send it directly to the incinerator for combustion. The incinerated material enters the boiler ash, with no excess waste generated. There is no need to set up a complete wastewater treatment system, which reduces the land area and lowers investment and operating costs.

[0037] 2. By setting up a moving seat, a lifting seat, and a fixed shaft, the agitator can rotate, move horizontally, and move vertically, expanding the range of action of the agitator and enabling it to fully agitate the wastewater in the collection tank, preventing sedimentation and condensation, and further improving the wastewater treatment effect.

[0038] In summary, the beneficial effects of this utility model are: it can achieve zero-discharge treatment of wastewater, reduce investment and operating costs, and fully stir the wastewater in the collection tank to prevent sedimentation and coagulation, thus ensuring good wastewater treatment results.

[0039] Of course, there may be many other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
