Description

Technical Field

[0001] This utility model belongs to the field of polyaluminum chloride flocculant dispensing technology, and in particular relates to a polyaluminum chloride flocculant dispensing machine. Background Technology

[0002] Polyaluminum chloride (PAC), as a highly efficient inorganic polymeric flocculant, is widely used in drinking water purification, industrial wastewater treatment, and municipal sewage treatment. Its core advantage lies in its ability to rapidly remove colloids, heavy metal ions, and organic pollutants from water through charge neutralization and bridging, significantly improving water clarity.

[0003] Comparing with Chinese Patent CN223187715U, which discloses an automatic dispenser for polyaluminum chloride flocculant, the device includes a storage tank. A second cover is fixed to the upper end of the storage tank, and uniformly distributed second support columns are fixed to the upper end of the second cover. A stirring assembly, including a stirring tank, is located at the upper end of each of the uniformly distributed second support columns. A frustum block is fixed to the lower end of the inner wall of the storage tank, and a uniformly distributed first trough is formed through the lower end of the inner wall of the storage tank. A dispensing assembly is located on the inner wall of the first trough. When storing polyaluminum chloride flocculant through a U-shaped tube, its structure keeps the liquid at both ends of the tube parallel. When the polyaluminum chloride flocculant in the U-shaped tube reaches the float position of the water level control valve, the valve is closed to discharge the flocculant, thus achieving quantitative dispensing.

[0004] However, the aforementioned patent requires pauses during dispensing and handling, which increases auxiliary idle time and significantly reduces the dispensing speed of polyaluminum chloride flocculant. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a polyaluminum chloride flocculant dispensing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A polyaluminum chloride flocculant dispensing machine includes a workbench with conveyor belts symmetrically arranged on both sides for conveying dispensing tanks in and out. It also includes an inner support device in the center of the workbench for central support and fixation. An outer support device is arranged around the inner support device to hold the dispensing tanks in place for rotation. Several injection pipes are evenly distributed around the circumference of the outer support device, with electrically controlled flow valves installed at the top of each injection pipe. A drive device providing rotational power is located at the top of the outer support device. The inner support device includes an inner cylinder fixedly installed in the center of the workbench, with guide grooves on its outer circumference that rise and fall in a ring along the outer circumference of the inner cylinder. The outer support device includes a rotating disk rotatably mounted in the center of the workbench, with several limiting slots evenly distributed around its circumference. An outer cylinder is mounted on the rotating disk, covering the outer circumference of the inner cylinder. Several limiting grooves are evenly distributed vertically around the circumference of the outer cylinder, with lifting components slidably arranged within these grooves to hold the injection pipes in place for vertical movement.

[0008] Furthermore: The top of the outer casing is equipped with a liquid equalization assembly for dispersing and conveying polyaluminum chloride flocculant. The liquid equalization assembly includes a liquid equalization pan fixedly installed on the top of the outer casing. Several distributing pipes are evenly distributed around the circumference of the liquid equalization pan. Infusion hoses are installed on the distributing pipes, and the infusion hoses are connected to the injection pipes by clamps.

[0009] Furthermore: a support shaft is provided at the top of the inner cylinder, an infusion channel is provided in the middle of the support shaft, an inlet connector is installed at the bottom of the inner cylinder, and the liquid distribution plate is connected to the support shaft by a sealed bearing.

[0010] Furthermore, the outer support device is symmetrically equipped with guide baffles at the front and rear to guide the rotation of the dispensing tank. The guide baffles consist of two parts: a straight section distributed along the conveyor belt and an arc section distributed along the circumference of the rotating disk.

[0011] Furthermore, the lifting assembly includes a lifting carriage that slides along a limiting slide groove and a limiting slide post that slides along a guide groove, with the limiting slide post fixedly disposed behind the lifting carriage.

[0012] Furthermore, the drive unit includes a cantilever fixed on the workbench and a driven gear fixed on the top surface of the liquid equalization plate. A servo motor is mounted on the cantilever, and a drive gear is mounted on the output end of the servo motor. The drive gear and the driven gear mesh and transmit power.

[0013] Compared with existing technologies, the beneficial effects are:

[0014] Through unique mechanical structural innovation, rotary motion and lifting motion are organically integrated, enabling continuous operation of multi-station synchronous, precise insertion filling. This achieves automatic loading, station switching, and unloading of filling tanks. The entire filling process requires no manual intervention in tank handling and positioning, forming a highly efficient continuous production line that significantly improves filling efficiency and reduces labor intensity and production costs. Multiple filling tanks can be filled simultaneously on the rotary table; this "one-turn-multiple-fills" design concept transforms intermittent operation into continuous batch operation, increasing the number of filling tanks per unit time (production capacity). The efficiency is significantly improved, making it particularly suitable for large-scale industrial production. Utilizing a special annular guide groove on the fixed inner cylinder in conjunction with a limiting slide column, the rotational motion of the outer support is precisely converted into the periodic lifting motion of the filling pipe. This mechanical linkage mechanism eliminates the need for an additional independent lifting power source, simplifying the control system and improving the reliability and coordination of equipment operation. The filling pipe is inserted into the tank during dispensing via the lifting assembly and then pulled out after filling. This process effectively prevents highly corrosive flocculants from splashing during filling, ensuring a clean and safe working environment and reducing material waste. Attached Figure Description

[0026] Please see Figures 1-6 A polyaluminum chloride flocculant dispensing machine includes a workbench 1, with conveyor belts 2 symmetrically arranged on both sides of the workbench 1 for conveying dispensing tanks in and out, and an inner support device 4 for central support and fixation in the middle of the workbench 1. An outer support device 5 for holding the dispensing tanks to rotate is arranged around the outer periphery of the inner support device 4. Several injection pipes 7 are evenly distributed around the circumference of the outer support device 5. An electrically controlled flow valve 8 is installed at the top of the injection pipe 7. A drive device 6 for providing rotational power is arranged at the top of the outer support device 5.

[0027] In this embodiment: the inner support device 4 includes an inner box cylinder 41 fixedly installed in the middle of the workbench 1. A guide groove 43 is provided on the outer periphery of the inner box cylinder 41. The guide groove 43 is arranged in a ring along the outer periphery of the inner box cylinder 41 from low to high and then from high to low. A support shaft 44 is provided at the top of the inner box cylinder 41. A liquid delivery channel 45 is provided in the middle of the support shaft 44. A liquid inlet connector 42 is installed at the bottom of the inner box cylinder 41. The liquid distribution plate 55 and the support shaft 44 are connected by a sealed bearing. When the guide groove 43 of the inner box cylinder 41 moves in the circumferential direction of the limiting slide column 59, it limits the limiting slide column 59 to move up and down. The polyaluminum chloride flocculant flows into the liquid delivery channel 45 between the inner box cylinder 41 and the support shaft 44 through the liquid inlet connector 42, and flows into the liquid distribution plate 55 from the liquid delivery channel 45.

[0028] In this embodiment: the outer support device 5 includes a rotating disk 52 rotatably mounted in the middle of the workbench 1. Several limiting slots 53 are evenly distributed around the circumference of the rotating disk 52. An outer casing 51 is mounted on the rotating disk 52, covering the outer circumference of the inner casing 41. Several limiting grooves 54 are evenly and vertically distributed around the circumference of the outer casing 51. A lifting assembly for clamping and moving the infusion tube 7 up and down is slidably mounted within the limiting grooves 54. A liquid equalization assembly for dispersing and conveying polyaluminum chloride flocculant is mounted on the top of the outer casing 51. The liquid equalization assembly includes a liquid equalization plate 55 fixedly mounted on the top of the outer casing 51. Several distributing pipes 56 are evenly distributed around the circumference of the liquid equalization plate 55. Infusion hoses 57 are installed on the distributing pipes 56, and the infusion hoses 57 and the infusion tube 7 are connected by clamps. The lifting assembly includes a lifting slide 58 that slides along the limiting grooves 54 and a lifting slide 58 that slides along the limiting grooves 54. The guide groove 43 slides with a limiting slide post 59, which is fixedly set behind the lifting slide 58. The equalization plate 55 and the outer box cylinder 51 rotate under the support of the workbench 1, while the rotating disk 52 at the bottom of the outer box cylinder 51 drives the dispensing tank to rotate under the limitation of the guide baffle 3. At the same time, the outer box cylinder 51 pushes the lifting slide 58 and the limiting slide post 59 to move circumferentially. Since the limiting slide post 59 slides along the guide groove 43, under the action of oblique separation, the limiting slide post 59 pushes the lifting slide 58 to move up and down along the limiting slide groove 54, driving the filling pipe 7 to circumferentially circulate, inserting and pulling out the dispensing tank. When the filling pipe 7 is inserted into the dispensing tank, the corresponding electric flow valve 8 opens to dispense. At this time, the polyaluminum chloride flocculant flows into the equalization plate 55 and finally enters the filling pipe 7 through the dispensing pipe 56 and the infusion hose 57 and is poured into the dispensing tank.

[0029] In this embodiment: the driving device 6 includes a cantilever frame 61 fixed on the workbench 1 and a passive gear 64 fixed on the top surface of the liquid equalization plate 55. A servo motor 62 is mounted on the cantilever frame 61, and an active gear 63 is mounted on the output end of the servo motor 62. The active gear 63 and the passive gear 64 mesh and transmit power. The cantilever frame 61 supports the servo motor 62 to drive the active gear 63 to mesh with the passive gear 64, thereby driving the liquid equalization plate 55 and the outer casing 51 to rotate under the support of the workbench 1.

[0030] In this embodiment: the outer support device 5 is symmetrically provided with guide baffles 3 for guiding the rotation of the dispensing tank. The guide baffles 3 are composed of two parts: a straight section distributed along the conveyor belt 2 and an arc section distributed along the circumference of the rotating disk 52. Before dispensing, the conveyor belt 2 at one end of the workbench 1 supports the dispensing tank and sends it into the limiting slot 53 of the rotating disk 52 along the guide baffles 3. During dispensing, the rotating disk 52 drives the dispensing tank to rotate under the limitation of the guide baffles 3. After dispensing, the rotating disk 52 pushes the dispensing tank into the conveyor belt 2 at the other end of the workbench 1 and moves away from the workbench 1 under the support of the conveyor belt 2.

[0031] Working principle: The conveyor belt 2 at one end of the workbench 1 carries the dispensing tank and feeds it into the limiting slot 53 of the rotating disk 52 along the guide baffle 3. The cantilever frame 61 supports the servo motor 62, which drives the active gear 63 to mesh with the passive gear 64, causing the equalization plate 55 and the outer box cylinder 51 to rotate under the support of the workbench 1. The rotating disk 52 at the bottom of the outer box cylinder 51 drives the dispensing tank to rotate under the limitation of the guide baffle 3. At the same time, the outer box cylinder 51 pushes the lifting slide 58 and the limiting slide column 59 to move circumferentially. Since the limiting slide column 59 slides along the guide groove 43, under the action of oblique separation, the limiting slide column 59 pushes the lifting slide 58. The filling tube 7 moves up and down along the limiting slide 54, driving the filling tube 7 to circulate in a circumferential manner, inserting and pulling out of the dispensing tank. When the filling tube 7 is inserted into the dispensing tank, the corresponding electrically controlled flow valve 8 opens, and the polyaluminum chloride flocculant flows into the delivery channel 45 between the inner tank cylinder 41 and the support shaft 44 through the liquid inlet connector 42, and flows into the equalization plate 55 from the delivery channel 45. Finally, it enters the filling tube 7 through the distribution pipe 56 and the delivery hose 57 and is poured into the dispensing tank. After the dispensing is completed, the filling tube 7 is pulled out of the dispensing tank. At the same time, the rotating disk 52 pushes the dispensing tank into the conveyor belt 2 at the other end of the workbench 1, and it moves away from the workbench 1 under the support of the conveyor belt 2.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
