Technical Field

[0001] This utility model relates to the technical field of special chemical storage cabinets, specifically to a liquid special chemical storage cabinet. Background Technology

[0002] A chemical conveying system is used to transport the chemicals needed for manufacturing processes to the factory area in drums or tank trucks. Under safe and quality-compliant conditions, it automatically supplies and delivers these chemicals to the various process machines on the production line according to their requirements. A chemical conveying system includes chemical conveying equipment, valve boxes, monitoring systems, and pipelines. In the event of an interruption in the transportation process, the chemicals inside the pipeline need to flow back to the internal storage bottles in the storage cabinet for temporary storage.

[0003] Currently, the storage bottles inside existing specialty chemical storage cabinets make it inconvenient to promptly remove returned liquid chemicals after storage, affecting the temporary storage of subsequent returned liquid chemicals.

[0004] In summary, there is a current need for a special liquid chemical storage cabinet. Utility Model Content

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

[0007] A liquid special chemical storage cabinet includes a cabinet body. Two liquid storage bottles are installed inside the cabinet body. A liquid level sensor is installed through the upper end of each liquid storage bottle. A vacuum pump is connected to the side of each liquid storage bottle. The output port of the vacuum pump is connected to a connecting housing via a first connecting pipe. The connecting housing is located inside the cabinet body. A first solenoid valve is installed on the first connecting pipe. The lower end of the connecting housing is connected to a first infusion pump via a second connecting pipe. A second solenoid valve is installed on the second connecting pipe. The first infusion pump is connected to the liquid storage bottles via a third connecting pipe. A controller is located on the left side of the cabinet body.

[0008] Furthermore, the upper end of the connecting housing is connected to the second infusion pump via a fourth connecting pipe, the second infusion pump is connected to a fifth connecting pipe, and the two fifth connecting pipes and the two storage bottles are respectively connected to a diverting valve body.

[0009] Furthermore, the steering valve body includes a first valve pipe, which is connected to the upper part of the steering valve body, and two second valve pipes are connected to the lower part of the steering valve body.

[0010] Furthermore, the upper second valve tube is connected to the fifth connecting tube, and the lower second valve tube is connected to the liquid storage bottle.

[0011] Furthermore, the steering valve body also includes a third solenoid valve, which is installed on the second valve pipe.

[0013] This invention provides a liquid special chemical storage cabinet. Compared with the prior art, it has the following advantages:

[0014] Beneficial effects:

[0015] First, the air pump on the left draws a suitable amount of gas from the left storage bottle into the corresponding connecting housing, creating negative pressure inside the left storage bottle to facilitate the inflow of liquid chemicals. When the returning liquid chemicals enter the left storage bottle through the first valve tube below, the diverting valve body, and the second valve tube on the lower left, the liquid level sensor on the left monitors the liquid level in the storage bottle. When it is detected that an appropriate amount of liquid chemicals is stored in the left storage bottle, the motor and shaft below drive the valve plate to rotate, allowing the subsequent liquid chemicals to flow into the right storage bottle. At the same time, the first infusion pump on the left draws the returned liquid chemicals collected in the left storage bottle into the connecting housing, and then the second infusion pump delivers them out through the diverting valve body above, facilitating the subsequent collection, storage, and use of the returned liquid chemicals.

[0024] To address the technical problems in the background section, the following liquid special chemical storage cabinet is provided:

[0025] Combination Figures 1-4 As shown, the present invention provides a liquid special chemical storage cabinet, including a cabinet body 1. Two liquid storage bottles 2 are installed inside the cabinet body 1. A liquid level sensor 3 is installed through the upper end of the liquid storage bottle 2. A vacuum pump 4 is connected to the side of the liquid storage bottle 2. The output port of the vacuum pump 4 is connected to a connecting housing 6 through a first connecting pipe 5. The connecting housing 6 is located inside the cabinet body 1. A first solenoid valve 7 is installed on the first connecting pipe 5. The lower end of the connecting housing 6 is connected to a first infusion pump 9 through a second connecting pipe 8. A second solenoid valve 11 is installed on the second connecting pipe 8. The first infusion pump 9 is connected to the liquid storage bottle 2 through a third connecting pipe 10. A controller 16 is installed on the left side of the cabinet body 1.

[0026] The gas in the corresponding liquid storage bottle 2 is drawn into the corresponding connecting housing 6 by the vacuum pump 4, so that a negative pressure is formed in the liquid storage bottle 2, which helps the liquid chemicals to flow in.

[0027] In this embodiment, the upper end of the connecting housing 6 is connected to the second infusion pump 13 via the fourth connecting pipe 12. The second infusion pump 13 is connected to the fifth connecting pipe 14. The two fifth connecting pipes 14 and the two storage bottles 2 are respectively connected to a diverting valve body 15.

[0028] Through the diversion valve body 15, when an appropriate amount of liquid chemicals is loaded into one storage bottle 2, the subsequent liquid chemicals are returned to another storage bottle 2 under the action of the diversion valve body 15.

[0029] Example 2

[0030] like Figures 1-4 As shown, based on the above embodiments, this embodiment further provides the following:

[0031] In this embodiment, the steering valve body 15 includes a first valve pipe 1501. The first valve pipe 1501 is connected to the upper part of the steering valve body 15, and two second valve pipes 1502 are connected to the lower part of the steering valve body 15. The upper second valve pipe 1502 is connected to the fifth connecting pipe 14, and the lower second valve pipe 1502 is connected to the liquid storage bottle 2. The steering valve body 15 also includes a third solenoid valve 1503, which is installed on the second valve pipes 1502. The steering valve body 15 also includes a rotating shaft 1504, which is rotatably connected to the inner wall of the steering valve body 15. The inner end of the rotating shaft 1504 is connected to the valve plate 1505, and one side of the rotating shaft 1504 passes through the steering valve body 15 and is connected to the output shaft of the motor 1506.

[0032] The valve plate 1505 is rotated by the motor 1506 and the rotating shaft 1504 to control the direction of the return of the liquid chemicals, so that the two storage bottles 2 are used alternately for the temporary storage of the return of liquid chemicals.

[0033] Working principle and usage process of this utility model:

[0034] In use:

[0035] Step 1: Open the first solenoid valve 7 on the left side, and use the air pump 4 on the left side to draw an appropriate amount of gas from the liquid storage bottle 2 on the left side into the connecting housing 6 on the left side. Close the first solenoid valve 7 to create a negative pressure in the liquid storage bottle 2, which helps the liquid chemicals to flow in. The backflowing liquid chemicals pass through the first valve pipe 1501 below, the diverting valve body 15, and the second valve pipe 1502 on the lower left side. Open the corresponding third solenoid valve 1503 to allow the liquid chemicals to enter the liquid storage bottle 2 on the left side. At the same time, the first solenoid valve 7 on the right side can be opened, and the air pump 4 on the right side draws an appropriate amount of gas from the liquid storage bottle 2 on the right side into the connecting housing 6 on the right side. Close the first solenoid valve 7.

[0036] Step 2: The liquid level in the storage bottle 2 is monitored by the liquid level sensor 3 on the left. When the liquid level is detected to be an appropriate amount of liquid chemicals in the storage bottle 2 on the left, the controller 16 controls the valve plate 1505 to rotate through the motor 1506 and the rotating shaft 1504 below, so that the subsequent liquid chemicals flow into the storage bottle 2 on the right through the diverting valve body 15 below and the second valve pipe 1502 on the lower right.

[0037] Step 3: Open the second solenoid valve 11 on the left, and use the first infusion pump 9 on the left to draw the liquid chemicals collected in the left storage bottle 2 back into the connecting housing 6. Open the third solenoid valve 1503 on the upper left, and use the second infusion pump 13, the fourth connecting pipe 12 and the fifth connecting pipe 14 to deliver the liquid chemicals through the second valve pipe 1502, the diverting valve body 15 and the first valve pipe 1501 on the upper left.
