The sleeve is provided with an injection hole communicating with the input end of the injection nozzle, and the other end of the inlet channel is correspondingly arranged with the injection hole. The opening / closing actuator is used to drive the slide rod to slide up and down along the inside of the sleeve. Furthermore, when the injection hole coincides with the outlet end of the inlet channel, the inside of the standard measuring cylinder is connected to the inside of the injection nozzle through the inlet channel; the sleeve is slidably and sealingly connected to the outer wall of the slide rod, and more specifically, a sealing ring is fitted on the slide rod, and the slide rod and the sleeve are slidably and sealingly connected through the sealing ring.

[0006] The opening and closing actuator can be a telescopic cylinder or other equivalent component that can drive the slide bar to move up and down; the top of the liquid storage tank is equipped with multiple vent pipes that communicate with the outside atmosphere.

[0007] Preferably, the opening and closing actuator includes a turntable rotatably mounted on a frame and a rotary drive component that provides power for the rotation of the turntable.

A cross brace is fixedly mounted at the bottom of the slide rod, and a drive rod is fixedly mounted at the bottom of the cross brace. A ball bearing is rotatably mounted at the bottom of the drive rod. Multiple conical protrusions corresponding to the U-shaped opening slots are mounted on the turntable, and the drive rod is located above one of the corresponding conical protrusions.

[0008] Furthermore, the rotary drive component is preferably a braked stepper motor, but other equivalent components such as a pneumatic rotary cylinder that can drive the turntable to rotate at a fixed angle can also be used; the U-shaped opening placement slot is used to place the packaging container containing the polyaluminum chloride flocculant.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] Example 1 Please refer to Figure 1-4 An automatic dispenser for polyaluminum chloride flocculant includes a frame 1, a mounting bracket 2 fixedly mounted on the frame 1, a storage tank 3 fixedly mounted on the mounting bracket 2, a quantitative dispensing mechanism, and an opening / closing actuator for opening and closing the quantitative dispensing mechanism. The quantitative dispensing mechanism includes a sleeve 4 fixedly mounted on the bottom of the storage tank 3 and communicating with the inside of the storage tank 3, a slide rod 5 slidably mounted inside the sleeve 4, a standard measuring cylinder 6 mounted on the top of the slide rod 5, and an injection nozzle 7 mounted on the outer wall of the sleeve 4. The slide rod 5 is provided with an inlet channel 8, one end of which communicates with the inside of the standard measuring cylinder 6. The sleeve 4 is provided with an injection hole 9 communicating with the input end of the injection nozzle 7, and the other end of the inlet channel 8 is correspondingly provided with the injection hole 9. The opening / closing actuator is used to drive the slide rod 5 to slide up and down along the inside of the sleeve 4. Furthermore, when the injection hole 9 coincides with the outlet end of the inlet channel 8, the inside of the standard measuring cylinder 6 is connected to the inside of the injection nozzle 7 through the inlet channel 8; a switch valve 24 is installed on the injection nozzle 7; furthermore, the switch valve 24 is used to control the opening and closing of the outlet end of the injection nozzle 7.

[0027] The sleeve 4 and the outer wall of the slide rod 5 are slidably sealed. More specifically, a sealing ring is fitted on the slide rod 5, and the slide rod 5 and the sleeve 4 are slidably sealed through the sealing ring. The opening and closing actuator can be a telescopic cylinder or other equivalent component that can drive the slide rod 5 to move up and down. The top of the liquid storage tank 3 is provided with multiple vent pipes that communicate with the outside atmosphere. The liquid storage tank 3 is preferably a transparent cylinder so that the operator can observe the liquid level in the liquid storage tank 3 in real time. When the liquid level in the liquid storage tank 3 is low, it can be detected and replenished in time. It can also be detected in time whether the standard measuring cylinder 6 is full of polyaluminum chloride flocculant.

[0028] The standard measuring cylinder 6 and the slide bar 5 are detachably connected; furthermore, the bottom of the standard measuring cylinder 6 is provided with an internal threaded sleeve, and the top of the slide bar 5 is provided with a threaded part, which is screwed into the threaded sleeve; the total capacity of the polyaluminum chloride flocculant in the standard measuring cylinder 6 and the liquid inlet channel 8 is the standard dispensing amount of the dispensing polyaluminum chloride flocculant.

[0029] A pressure sensor 23 is installed on the mounting bracket 2, and the liquid storage tank 3 is connected to the mounting bracket 2 through the pressure sensor 23; furthermore, the pressure sensor 23 can transmit the weight change value in the liquid storage tank 3 to an external processor and display the value on a display device such as a monitor.

[0030] The applicability of the device can be improved by replacing the standard measuring cylinder 6 with one of different volumes to meet the dispensing requirements of polyaluminum chloride flocculants in containers of different volumes. Before dispensing the polyaluminum chloride flocculants, the pressure value M1 at the liquid storage tank 3 is measured by the pressure sensor 23. After the polyaluminum chloride flocculants are dispensed, the pressure value M2 at the liquid storage tank 3 is measured by the pressure sensor 23. The difference M between M1 and M2 is the dispensing amount of polyaluminum chloride flocculants. The value is converted by an external processor and compared with the total weight M' of polyaluminum chloride flocculants in the standard measuring cylinder 6 and the liquid inlet channel 8. If the two values ​​M and M' are the same or within the allowable error range, it means that the dispensing amount of polyaluminum chloride flocculants is accurate. If the two values ​​are different, there is a dispensing error, which prompts the operator to deal with it in time. This secondary verification of the dispensing amount of polyaluminum chloride flocculants further improves the dispensing accuracy of polyaluminum chloride flocculants. When the container is below the injection nozzle 7, the switch valve 24 is opened, and the polyaluminum chloride flocculant is injected into the container from the injection nozzle 7. This is to prevent the polyaluminum chloride flocculant from flowing out of the injection nozzle 7 when the inlet channel 8 is connected to the injection hole 9, thereby reducing the waste of polyaluminum chloride flocculant.

[0031] The opening and closing actuator includes a turntable 10 rotatably mounted on a frame 1 and a rotary drive component 11 that provides power for the rotation of the turntable 10. The edge of the turntable 10 has multiple circumferentially distributed U-shaped opening slots 12, with the injection nozzle 7 located directly above one of the U-shaped opening slots 12. A cross brace 13 is fixedly mounted on the bottom of the slide rod 5, and a drive rod 14 is fixedly mounted on the bottom of the cross brace 13. A ball bearing 15 is rotatably mounted on the bottom of the drive rod 14. Multiple conical protrusions 16, corresponding to the U-shaped opening slots 12, are mounted on the turntable 10, with the drive rod 14 located above one of the corresponding conical protrusions 16. Furthermore, the rotary drive component 11 is preferably a braked stepper motor, but other equivalent components capable of driving the turntable 10 to rotate at a fixed angle, such as a pneumatic rotary cylinder, can also be used. The U-shaped opening slots 12 are used to hold packaging containers containing polyaluminum chloride flocculant.

[0032] Please refer to Figure 1 and Figure 3A guide rod 17 is fixedly installed on the cross brace 13, and a guide plate 18 is fixedly installed on the outer wall of the sleeve 4. The guide plate 18 is provided with a sliding hole that fits with the outer wall of the guide rod 17, and the guide rod 17 is installed in the sliding hole in a sliding manner.

[0033] A spring 19 is fitted on the guide rod 17. One end of the spring 19 abuts against the guide plate 18, and the other end of the spring 19 abuts against the cross brace 13.

[0034] For details, please refer to Figures 3-5 A counterweight plate 20, which fits into the inner wall of the storage tank 3, is fixedly installed on the slide rod 5. The counterweight plate 20 has multiple through holes 21 that allow polyaluminum chloride flocculant to pass through. Furthermore, the counterweight plate 20 can slide up and down inside the storage tank 3 along with the slide rod 5. A guide impeller 22 is fixedly installed inside the through holes 21.

[0035] The container can be placed in the U-shaped opening slot 12 on the turntable 10. The rotating drive 11 drives the turntable 10 to rotate at a certain angle, and the container is just below the injection nozzle 7. In the initial state, the drive rod 14 is located in the recess between two adjacent conical protrusions 16, and the bottom outlet of the liquid inlet channel 8 is located below the injection hole 9. As the turntable 10 rotates, the top of the corresponding set of conical protrusions 16 contacts the ball bearing 15. After being driven by the drive rod 14 and the cross brace 13, the slide rod 5 moves upward along the sleeve 4. At this time, the liquid inlet channel 8 coincides with the injection hole 9, thus realizing the upward drive of the slide rod 5 and the automatic feeding of the container to the injection nozzle 7, improving the automation level of the equipment.

[0036] Guide rod 17 and guide plate 18 limit the vertical sliding of cross brace 13 to prevent slide rod 5 from rotating, thus ensuring smooth alignment of liquid inlet channel 8 and injection hole 9. When drive rod 14 is above conical protrusion 16, spring 19 is compressed. When drive rod 14 is in the recess between two adjacent conical protrusions 16, spring 19 extends and pushes cross brace 13 downward, causing standard measuring cylinder 6 to move down and reset, immersing it in polyaluminum chloride flocculant in storage tank 3. Counterweight plate 20 increases the reset gravity of standard measuring cylinder 6, further ensuring smooth downward movement of standard measuring cylinder 6 until the top of standard measuring cylinder 6 is below the surface of polyaluminum chloride flocculant in storage tank 3. During the vertical movement of counterweight plate 20, polyaluminum chloride flocculant passes through through hole 21, and guide impeller 22 agitates the passing polyaluminum chloride flocculant, improving the uniformity of component distribution within the polyaluminum chloride flocculant.

[0037] The automatic dispensing device for polyaluminum chloride flocculant provided by this utility model is used as follows: The external container is placed in the U-shaped opening placement groove 12. At this time, the drive rod 14 is located in the recess between two adjacent conical protrusions 16. The standard measuring cylinder 6 is completely immersed below the liquid surface in the storage tank 3. The standard measuring cylinder 6 and the liquid inlet channel 8 are filled with polyaluminum chloride flocculant. The bottom outlet end of the liquid inlet channel 8 is located below the injection hole 9 and is blocked by the inner wall of the sleeve 4. The rotating drive component 11 drives the turntable 10 to move. The container moves to below the injection nozzle 7. At this time, the drive rod 14 is located at the top of the corresponding conical protrusion 16. The drive rod 14, the cross brace 13 and the slide rod 5 are connected to the container. After transmission, the standard measuring cylinder 6 moves upward until the top of the standard measuring cylinder 6 is higher than the liquid level in the storage tank 3. Excess polyaluminum chloride flocculant in the standard measuring cylinder 6 overflows into the storage tank 3. At this time, the outlet end of the liquid inlet channel 8 is aligned and connected with the injection hole 9. The switch valve 24 is opened, and the polyaluminum chloride flocculant is injected into the corresponding container through the liquid inlet channel 8, the injection hole 9 and the injection nozzle 7. The total weight of the liquid in the standard measuring cylinder 6 and the liquid inlet channel 8 is compared with the weight reduction value measured by the pressure sensor 23. If the two values ​​are within the allowable error range, the amount of polyaluminum chloride flocculant dispensed meets the requirements. The polyaluminum chloride flocculant can be dispensed in this way repeatedly.
