Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically to an integrated dosing device for sludge dewatering. Background Technology

[0002] Sludge is formed by the long-term accumulation of mud in river channels. When processing the dredged sludge, it is dewatered to solidify it. During the dewatering process, some chemicals need to be added. To ensure the chemicals work better, they are mixed with other liquids and then introduced into the sludge dewatering system. In order to ensure the supply of chemicals, large containers are used for storage. However, conventional chemical dosing devices still use top dosing, adding the chemicals from above the liquid, which cannot allow the chemicals to be dispensed layer by layer within the liquid. This requires a long time to mix the chemicals and liquid evenly, resulting in low work efficiency.

[0003] A search revealed an integrated dosing device for a sludge dewatering system, with publication number CN223255108U. This device includes a housing and a dry powder dosing tank.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 An integrated dosing device for sludge dewatering includes a cylindrical chemical tank 1 with an open top. Two fixing plates 7 are welded to the side of the chemical tank 1. A hydraulic cylinder 8 for providing linear driving force is fixedly installed at the bottom of the fixing plates 7. The output axis of the hydraulic cylinder 8 extends upward, passes through the fixing plates 7, and is fixedly connected to a driven block 6. A disc-shaped top cover 5 connects the two driven blocks 6 and closes the top of the chemical tank 1 to seal the opening at the top of the chemical tank 1. To facilitate the discharge of liquid medicine from the medicine tank 1, a drain pipe 23 is fixedly connected to the lower side of the medicine tank 1. A valve is installed on the drain pipe 23 to open and close the drain pipe 23. An injection pipe is fixedly connected to the upper side of the medicine tank 1. The hydraulic cylinder 8 automates the up-and-down movement of the top cover 5. Every sludge dewatering system has a control box structure. The two hydraulic cylinders 8 are also electrically connected to the control box of the sludge dewatering system. The control box controls the two hydraulic cylinders 8, enabling them to work synchronously.

[0022] A bearing 25 is installed in the groove at the top of the top cover 5. A central cylinder 2 extending into the medicine tank 1 is installed on the bearing 25. The central cylinder 2 is a hollow cylindrical structure with an open bottom. The inner and outer rings of the bearing 25 can rotate relative to each other. The outer ring is fixedly connected to the top cover 5, and the inner ring is fixedly connected to the surface of the central cylinder 2. This allows the central cylinder 2 to rotate relative to the top cover 5. When the top cover 5 is driven upward by the hydraulic cylinder 8, it will drive the central cylinder 2 upward through the bearing 25. Several stirring rods 3 are fixedly welded to the side of the central cylinder 2. When the central cylinder 2 rotates, the stirring rods 3 will stir and mix the medicine liquid in the medicine tank 1. A driven wheel 9 is fixedly connected to the surface of the central cylinder 2. Above the top cover 5, and in a recessed position, a drive motor 10 is fixedly installed to provide rotational driving force. The drive motor 10 is a low-speed motor, specifically a YE series low-speed gear motor. A drive wheel 11 is connected to the drive wheel 11 with an upward extension of its output shaft. The outer center of the drive wheel 11 is also recessed. The drive wheel 11 and the driven wheel 9 are connected by a belt 12. The recesses on the sides of the drive wheel 11 and the driven wheel 9 are the same width as the belt 12. The recesses prevent the belt 12 from accidentally detaching from the surfaces of the drive wheel 11 and the driven wheel 9. When the drive motor 10 is working, it can drive the central cylinder 2 to rotate through the drive wheel 11, the belt 12, and the driven wheel 9.

[0023] The stirring rods 3 are arranged vertically in two rows on the side of the central cylinder 2. Each stirring rod 3 has a pad 13 fixedly connected to its top. A rectangular medicine box 4, open at both the front and back, is fixedly connected to the top of each pad 13. As shown in the attached diagram, the medicine boxes 4 are arranged vertically in layers. A drive shaft 17, a circular cross-section strip shaft, is connected to the central cylinder 2. The drive shaft 17 can move up and down relative to the central cylinder 2. Two electric push rods 22 providing linear driving force are fixedly installed on the top plane of the top cover 5. The output shaft of each electric push rod 22 extends upwards and is connected to a protruding plate 21. The protruding plates 21 are connected by a fixing ring 20. The fixing ring 20 is a ring-like structure sleeved on the outside of the drive shaft 7. A bearing 26 is fixedly installed on its inner wall. The surface of the outer ring of the bearing 26 is fixedly connected to the fixing ring 20, and the inner wall of the inner ring is fixedly connected to the surface of the drive shaft 17. The bearing 26 has the characteristic that the inner and outer rings can rotate relative to each other. The purpose of this arrangement is that when the electric push rod 22 is working, it can drive the fixing ring 20 to move upward through the protruding plates 21. The fixing ring 20 will drive the drive shaft 17 to move upward through the bearing 26, and the fixed installation of the electric push rod 22 will not affect the rotation of the drive shaft 17.

[0024] The bottom end of the drive shaft 17 extends into the interior of the central cylinder 2, and several laterally extending crossbars 18 are fixedly connected to its side. The end of the crossbars 18 away from the drive shaft 17 extends to the outside of the central cylinder 2. In this technical solution, the crossbars 18 also need to move up and down relative to the central cylinder 2. A movement opening 19 is provided on the side of the central cylinder 2 for the crossbars 18. Thus, when the electric push rod 22 drives the protruding plate 21 to move upward, the setting of the movement opening 19 allows the crossbars 18 to also have an upward movement range. Furthermore, the front and rear dimensions of the movement opening 19 are... The crossbar 18 is of suitable thickness, and a lifting plate 14 is fixedly connected to its lateral extension end. The lifting plate 14 is positioned directly above the independent medicine box 4. Two side blocks 15 are fixedly connected to the bottom of the lifting plate 14, and sealing plates 16 are fixedly connected to the bottom of the side blocks 15. Below each lifting plate 14 are two sealing plates 16, which precisely block the openings on the front and rear sides of the independent medicine box 4. When the crossbar 18 is driven upward by the drive shaft 17, the sealing plates 16 will disengage from blocking the independent medicine box 4, and the stirring... During the mixing process, the central cylinder 2 also rotates, causing the liquid in the medicine tank 1 to directly flush the pre-filled medicine in the individual medicine boxes 4. When the top cover 5 moves upward due to the drive of the hydraulic cylinder 8, all the stirring rods 3 move to the outside of the medicine tank 1, thus moving each individual medicine box 4 to the outside of the medicine tank 1 as well. To allow medicine to be added to the individual medicine boxes 4 while the sealing plate 16 seals them, a feeding cover 24 is threaded onto the side of each individual medicine box 4. Rotating the feeding cover 24 allows it to be removed from the individual medicine box 4. After filling the individual medicine boxes 4 with medicine, although it takes a little time to pre-fill each individual medicine box 4 with medicine, this pre-filling work can be carried out when there is still a little medicine liquid left in the medicine tank 1. In this way, when medicine needs to be added, the medicine liquid left in the medicine tank 1 can be used to add medicine to the sludge dewatering system first. After the medicine is pre-filled in the individual medicine boxes 4, the medicine liquid in the medicine tank 1 can be used up, and the next medicine and liquid mixing work can be carried out. In addition, in order to facilitate the injection of liquid into the medicine tank 1, a water pipe is fixedly connected to the upper side of the medicine tank 1.

[0025] In use, liquid is introduced into the medicine tank 1 through the water pipe, and then the drive motor 10 works. The drive motor 10 drives the central cylinder 2 to rotate through the drive wheel 11, belt 12 and driven wheel 9. At the same time, the electric push rod 22 moves the protruding plate 21 upward. The protruding plate 21 drives the shaft 17 upward through the fixed ring 20 and bearing 26. The shaft 17 drives the lifting plate 14 upward through the crossbar 18. The lifting plate 14 drives the sealing plate 16 upward through the side block 15. The rotation of the central cylinder 2 drives the stirring rod 3 to move. The liquid in the medicine tank 1 flushes out the medicine pre-filled in the independent medicine box 4. The vertical row of independent medicine boxes 4 is a multi-layered arrangement, so the medicine enters the liquid synchronously and in multiple layers. The stirring rod 3 stirs the liquid and medicine, which can quickly mix the medicine and liquid. Open the valve on the drain pipe 23 to discharge the medicine liquid through the drain pipe 23.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
