[0034] Implementation Method 1

[0035] Reference Figures 1 to 6 This embodiment is an optional embodiment of this application, which discloses a Glauber's salt quantitative addition device, including a frame 1 and a controller 9. A temporary storage box 2 is provided on the top of the frame 1, and a feeding device is also provided on the frame 1.

[0036] Along the height direction of the temporary storage box 2, a feed pipe 3 is provided at the top of the temporary storage box 2, and a discharge pipe 4 is provided at the bottom. A regulating valve 5 for adjusting its on / off state is provided on the discharge pipe 4. The feeding device includes a conveyor belt 10 and a feeding pipe 11, wherein the conveyor belt 10 is used to transport sodium sulfate, the feeding pipe 11 is inclined, its outlet end is connected to the feed pipe 3, and a buffer box 13 is provided at its inlet end. The buffer box 13 is connected to the conveyor belt 10, and a feeding auger is also provided inside the feeding pipe 11.

[0037] The feeding auger can continuously supply sodium sulfate to the temporary storage box 2, which not only has a large supply capacity but also high supply efficiency.

[0038] Furthermore, a first detection hole 14 and a second detection hole 15 are provided on the outer peripheral surface of the temporary storage box 2. The first detection hole 14 is coaxially arranged with the second detection cylinder, and an infrared transmitter 16 is provided in the first detection hole 14, and a receiver 17 is provided in the second detection hole 15. The infrared transmitter 16 and the receiver 17 are respectively electrically connected to the controller 9.

[0039] When there is an excess of sodium sulfate in the temporary storage tank, the excess sodium sulfate will block the infrared transmitter 16 and receiver 17, causing the receiver 17 to be unable to receive the signal. This allows for a quick determination of whether the material in the temporary storage tank 2 exceeds the limit, preventing the temporary storage tank 2 from being overloaded and ensuring the safe operation of the equipment.

[0040] Furthermore, a quantitative dispensing tank 6 is also provided on the frame 1. The quantitative dispensing tank 6 is located directly below the temporary storage box 2. A feed inlet 7 is provided on the top of the quantitative dispensing tank 6. The discharge pipe 4 passes through the feed inlet 7 and is inserted into the quantitative dispensing tank 6. It should be noted that although the discharge pipe 4 is inserted into the quantitative dispensing tank 6, the discharge pipe 4 must not have any contact with the quantitative dispensing tank 6 to avoid affecting the measurement accuracy.

[0041] A weighing module is also provided between the quantitative dispensing tank 6 and the frame 1. The weighing module includes a plurality of weighing sensors 18, each weighing sensor 18 is disposed on the frame 1 and electrically connected to the controller 9. The weighing sensors 18 are evenly arranged around the axis of the quantitative dispensing tank 6. A support column 19 is also provided on the outer surface of the quantitative dispensing tank 6, and each support column 19 is connected to each of the weighing sensors 18.

[0042] The weighing module can quickly and accurately measure the weight of the quantitative dispensing tank 6 along with the material inside, improving detection accuracy. At the same time, during the dispensing process, the weighing module can also quickly sense the trend of weight change, thereby controlling the discharge volume and further improving dispensing accuracy.

[0043] The technical solution described in this application includes a temporary storage box 2 and a quantitative dispensing tank 6. Since the feeding auger is a continuous feeding process, while the quantitative dispensing is an intermittent dispensing process, the two processes have different working rhythms. At the same time, if quantitative dispensing is carried out continuously while feeding, the two processes will interfere with each other and seriously affect the dispensing accuracy. Therefore, the temporary storage box 2 can separate the quantitative dispensing tank 6 to avoid interference between feeding and quantitative dispensing.

[0044] When the amount of material in the quantitative dispensing tank 6 is insufficient, the material can be fed in by controlling the regulating valve 5. At the same time, the feeding amount in the quantitative dispensing tank 6 is monitored by the weighing module. The device is easy to operate.

[0045] Furthermore, a discharge port 8 is provided at the bottom of the quantitative dispensing tank 6, and a discharge control device is provided on the discharge port 8; the discharge control device includes an adjusting plate 20 and a linear motor 21, one end of the adjusting plate 20 is slidably inserted into the discharge port 8 along the length direction of the adjusting plate 20, and the other end is connected to the linear motor 21; a support frame 22 adapted to the linear motor 21 is also provided on the quantitative dispensing tank 6, and the linear motor 21 is mounted on the support frame 22;

[0046] Meanwhile, a support ring 23 is also provided inside the discharge port 8, and the top surface of the support ring 23 is in contact with the bottom surface of the adjustment plate 20;

[0047] The opening size of the discharge port 8 can be controlled by controlling the position of the adjusting plate 20 by the linear motor 21. Since the weighing module can monitor the weight of the quantitative dispensing tank 6 and the material inside it in real time, it can monitor the dispensing amount at any time and control the position of the adjusting plate 20 in real time according to the change of the dispensing amount, thereby gradually reducing the opening of the discharge port 8 and gradually closing the discharge port 8, which is conducive to further improving the dispensing accuracy.

[0048] Secondly, the aforementioned device enables fully automated quantitative dispensing, which helps improve dispensing efficiency.

[0049] Furthermore, a safety tube 24 is provided at the bottom of the quantitative dispensing tank 6, and a discharge port 25 is provided at the free end of the safety tube 24. The safety tube 24 is also provided with a pressure regulating module for controlling the opening and closing state of the discharge port 25.

[0050] The pressure regulating module includes a baffle 26 and a return spring 27. The baffle 26 is slidably disposed in the safety tube 24 along the flow direction of the material. The baffle 26 is located at the rear end of the discharge port 25. An adjusting rod 28 is also provided on the baffle 26.

[0051] A plurality of discharge ports 25 are provided on the outer circumference of the safety tube 24 around its axis. A sealing plate 30 is also provided at the free end of the safety tube 24 along its axis. A return spring 27 is sleeved on the adjusting rod 28. A pressing plate 29 is also provided on the adjusting rod 28. The adjusting rod 28 is slidably connected to the sealing plate 30. The return spring 27 abuts against the sealing plate 30 and the pressing plate 29 respectively.

[0052] When the material in the quantitative dispensing tank 6 is overloaded due to a malfunction, the excess material will squeeze the baffle 26, push one side of its discharge port 25, and eventually open the discharge port 25. At this time, the material is discharged from the discharge port 25 to reduce the weight of the quantitative dispensing tank 6 and effectively ensure the safe operation of the equipment.

[0053] The controller 9 includes an industrial control computer and a PLC, with the industrial control computer electrically connected to the PLC; each of the weighing sensors 18, the linear motor 21, and the regulating valve 5 is electrically connected to the PLC.

[0054] In use, Glauber's salt is fed into the temporary storage box through the feeding device, and then the Glauber's salt to be packaged is further fed into the quantitative dispensing tank through the temporary storage box. Since the temporary storage box and the quantitative dispensing tank are connected but separated from each other, the weight change of the quantitative dispensing tank can be accurately monitored through the weighing module, and the dispensing amount can be judged by the weight change. At the same time, the separation of the temporary storage box and the quantitative dispensing tank can also avoid interference caused by the weighing module, which is conducive to ensuring the dispensing accuracy.

[0055] Secondly, by opening the discharge port through the discharge control device, the sodium sulfate can fall quickly under its own gravity, thereby improving the dispensing efficiency of sodium sulfate.

[0056] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
