[0002] The sludge conditioner is a chemical additive used to improve the dewatering performance of sludge. In the process of sewage treatment, the dewatering treatment of sludge is an important link, because the volume of the dewatered sludge is small, which is convenient for transportation and subsequent treatment.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1 - 6The utility model provides a technical solution: a feeding device that is convenient for dissolving and dispersing sludge conditioning agents, including a pre-dissolution box 1, a feeding port 2 connected to the interior is opened on the upper surface of the pre-dissolution box 1, a feeding pipe 3 is fixedly connected to the upper surface of the pre-dissolution box 1, and the feeding pipe 3 is connected to the pre-dissolution box 1 through the feeding port 2. The upper surface of the pre-dissolution box 1 is fixedly connected to a motor 4, and the output shaft of the motor 4 rotates and penetrates into the interior of the pre-dissolution box 1. The output shaft of the motor 4 is fixedly connected to a first rotating rod 5, and the outer surface of the first rotating rod 5 is fixedly connected to a first stirring rod 6. A filter barrel 7 is provided inside the pre-dissolution box 1, and the upper end of the filter barrel 7 is fixedly connected to the top wall of the pre-dissolution box 1. The opening 2 is located on the upper side of the filter barrel 7. The first rotating rod 5 and the first stirring rod 6 are both located inside the filter barrel 7. The lower end of the first rotating rod 5 rotates to penetrate the lower surface of the filter barrel 7. The lower end of the first rotating rod 5 is fixedly connected to a horizontal plate 8. The upper surface of the horizontal plate 8 is fixedly connected to two vertical rods 9. The outer surface of the vertical rod 9 is fixedly connected to a second stirring rod 10. A first cavity 11 is provided inside the top plate of the pre-dissolution box 1. A connecting component is provided inside the first cavity 11. A crushing component is provided inside the feeding pipe 3. When the staff needs to pre-dissolve the sludge conditioner, they first start the motor 4 to drive the rotation of the first rotating rod 5 and the first stirring rod 6, and then the rotation of the first rotating rod 5 can drive the horizontal plate 8. The rotation of the horizontal plate 8 drives the movement of the vertical rod 9 and the second stirring rod 10, and then water is added to the interior of the pre-dissolution box 1. At this time, the first rotating rod 5 and the first stirring rod 6 can cooperate to stir the inside of the filter barrel 7, and the cooperation of the vertical rod 9 and the second stirring rod 10 can realize stirring of the outside of the filter barrel 7. Subsequently, the sludge conditioner is added to the inside of the feeding pipe 3. At this time, since the motor 4 is in the running state, the transmission of the connecting component will drive the crushing component to move, thereby realizing the preliminary crushing of the sludge conditioner in the agglomerated state entering the feeding pipe 3, breaking up the block raw materials, and then the sludge conditioner that has been preliminarily crushed will enter the filter barrel through the feeding port 2. 7 is mixed with water. At this time, the sludge conditioner entering the pre-dissolution box 1 can be fully dispersed through the rotation of the first rotating rod 5 and the first stirring rod 6, and the dissolution rate of the sludge conditioner in water is accelerated by stirring. When part of the conditioner is dissolved into smaller particles, it will pass through the filter barrel 7 to the outside of the filter barrel 7, and then be further dissolved and stirred by the setting of the vertical rod 9 and the second stirring rod 10. After the sludge conditioner is dissolved, it can be discharged through the lower discharge port. The above structure further ensures the dissolution rate and dispersion effect of the sludge conditioner, thereby improving the pre-dissolution effect of the sludge conditioner and ensuring the subsequent use effect of the sludge conditioner, and has high practicality.

[0026] Further, the connecting component includes a second rotating rod 12. The second rotating rod 12 is rotatably connected to the inside of the first cavity 11. The upper end of the second rotating rod 12 rotatably penetrates out of the pre-dissolving box body 1. An outer surface of one end of the second rotating rod 12 located inside the first cavity 11 is sleeved with a first pulley 13. An outer surface of one end of the output shaft of the motor 4 located inside the first cavity 11 is sleeved with a second pulley 14. A belt 15 is sleeved between the first pulley 13 and the second pulley 14 for transmission. The diameter of the second pulley 14 is twice that of the first pulley 13. By starting the motor 4, the rotation of the output shaft of the motor 4 can drive the rotation of the second pulley 14 at this time. At this time, the rotation of the first pulley 13 can be driven through the transmission of the belt 15. The rotation of the second rotating rod 12 can be driven through the rotation of the first pulley 13.

[0027] Further, the crushing component includes a fixing plate 16. The fixing plate 16 is fixedly sleeved inside the feeding pipe 3. The top of the fixing plate 16 is set as an arc surface. A second cavity 17 is formed inside the fixing plate 16. The upper end of the second rotating rod 12 rotatably penetrates into the inside of the second cavity 17 and is rotatably connected to the top wall of the second cavity 17. A third rotating rod 18 is rotatably connected to the inside of the second cavity 17. The lower end of the third rotating rod 18 rotatably penetrates into the inside of the feeding pipe 3. A belt transmission component 19 for transmission is arranged inside the second cavity 17. The belt transmission component 19 includes two transmission pulleys and a transmission belt. The two transmission pulleys are respectively sleeved on the outer surfaces of the second rotating rod 12 and the third rotating rod 18. The transmission belt is sleeved between the outer surfaces of the two transmission pulleys. A crushing rod 20 is fixedly connected to the outer surface of the third rotating rod 18. The rotation of the third rotating rod 18 can be realized through the rotation of the second rotating rod 12 and the transmission of the belt transmission component 19. At this time, the rotation of the crushing rod 20 can be realized through the rotation of the third rotating rod 18. Finally, the preliminary crushing of the raw materials located inside the feeding pipe 3 is realized. Through the cooperation of the connecting component and the crushing component, the preliminary crushing treatment of the sludge conditioner is facilitated. At the same time, no additional driving source needs to be set, reducing the production cost and procurement cost, and further improving the practicability of the device.

[0028] Furthermore, an L-shaped rod 21 is slidably connected inside the top plate of the pre-dissolution box body 1. A sealing plug 22 is fixedly connected to the upper surface of the cross bar of the L-shaped rod 21. The sealing plug 22 is conical in shape and is made of a flexible material, which can be made of rubber. Its main purpose is to seal the feeding port 2. The upper end of the L-shaped rod 21 is rotatably connected to a threaded rod 23. The threaded rod 23 threadedly penetrates out of the inside of the pre-dissolution box body 1. When the staff needs to adjust the feeding rate, by rotating the threaded rod 23, at this time, because the threaded rod 23 is threadedly connected to the pre-dissolution box body 1 and the L-shaped rod 21 is slidably connected to the pre-dissolution box body 1, when the threaded rod 23 rotates, it will drive the L-shaped rod 21 to move up and down. Thus, the movement of the sealing plug 22 is driven by the up and down movement of the L-shaped rod 21, so as to realize the adjustment of the discharging rate at the feeding port 2. Through the above structure, it is possible to avoid as much as possible the situation that it is not convenient to dissolve inside the pre-dissolution box body 1 due to excessive single feeding amount, and at the same time, it is also possible to avoid the problem of uneven distribution of raw materials inside the pre-dissolution box body 1, and improve the stirring efficiency of the first rotating rod 5 and the first stirring rod 6.

[0029] Furthermore, an installation frame 24 is fixedly sleeved outside the pre-dissolution box body 1. Through the setting of the installation frame 24, the staff can choose to hang and install the device or fix it by bolts, improving the flexibility of the device.

[0030] In the above embodiment, the maximum descending height of the L-shaped rod 21 is higher than the height of the first stirring rod 6. Therefore, the situation where the L-shaped rod 21 collides with the first stirring rod 6 will not occur. At the same time, the crushing rods 20 are arranged staggeredly, thereby improving the crushing effect on the raw materials.

[0031] Working principle:

[0032] When the feeding device for dissolving and dispersing the sludge conditioner is in use, when the staff needs to pre-dissolve the sludge conditioner, first start the motor 4 to drive the rotation of the first rotating rod 5 and the first stirring rod 6, and then the rotation of the first rotating rod 5 can drive the rotation of the horizontal plate 8, and the rotation of the horizontal plate 8 drives the movement of the vertical rod 9 and the second stirring rod 10, and then add water to the inside of the pre-dissolution box 1. At this time, the first rotating rod 5 and the first stirring rod 6 can cooperate to stir the inside of the filter barrel 7, and the cooperation of the vertical rod 9 and the second stirring rod 10 can achieve stirring of the outside of the filter barrel 7. Subsequently, the sludge conditioner is added to the inside of the feeding pipe 3. At this time, since the motor 4 is in operation, the transmission of the connecting component will drive the sludge conditioner to dissolve the sludge conditioner. The crushing component moves, thereby achieving preliminary crushing of the sludge conditioner in a lumped state entering the feeding pipe 3, breaking up the block raw materials, and then the sludge conditioner that has been preliminarily crushed will enter the interior of the filter barrel 7 through the feeding port 2 to be mixed with water. At this time, the rotation of the first rotating rod 5 and the first stirring rod 6 can make the sludge conditioner entering the pre-dissolution box 1 fully dispersed, and the dissolution rate of the sludge conditioner in water is accelerated by stirring. When part of the conditioner is dissolved into smaller particles, it will pass through the filter barrel 7 to the outside of the filter barrel 7, and then be further dissolved and stirred by the setting of the vertical rod 9 and the second stirring rod 10. After the sludge conditioner is dissolved, it can be discharged through the lower discharge port.
