Description

Technical Field

[0001] This utility model relates to the field of pesticide ingredient preparation technology, and in particular to a liquid high-level feeding device. Background Technology

[0002] The pesticide preparation workshop delivers liquid materials to the production equipment in the workshop. The existing method is to set up material barrels on the upper floor of the workshop and connect them to the material boxes in the lower floor workshop through a supply pipe. The material is then supplied to the lower floor material boxes intermittently through a manual valve.

[0003] Based on this, a float switch is installed inside the material box to control the opening and closing of the valve on the feed pipe.

[0004] The valves used above are generally ball valves, and there is a gap between the ball and the valve body. Therefore, regardless of the method used, the height difference between the material bucket and the material box can easily cause liquid to flow by gravity or siphon.

[0005] In the pesticide industry, liquid materials are generally organic solvents, which have certain toxicity and hazards. In the absence of safety measures, the free flow and siphoning phenomena can easily lead to material spillage, which has an impact on safety and the environment. Utility Model Content

[0006] The purpose of this invention is to solve the above problems by providing a liquid high-level feeding device that closes the pipeline through an angle seat valve and a diaphragm pump, blocking gravity flow and siphon channels to ensure the safety of feeding.

[0007] The technical solution adopted by this utility model is:

[0008] A liquid high-level feeding device includes a material tank, a feeding pipe, and a material box. The material tank is located at a high position, and the material box is located at a low position. The feeding pipe transports liquid material from the material tank to the material box. The device is characterized by having an angle seat valve and a diaphragm pump installed on the feeding pipe at the low position, and a float switch installed in the material box. The feeding device also includes a power source, an air source, and a solenoid valve. The air source is connected to the angle seat valve and the diaphragm pump via the solenoid valve, and the power source is connected to the solenoid valve via the float switch. When the material box is at a low liquid level, the float switch opens the solenoid valve, the air source opens the angle seat valve and the diaphragm pump, and the material tank feeds the material box. When the material box is at a high liquid level, the float switch closes the solenoid valve, the angle seat valve and the diaphragm pump close, and the feeding stops.

[0009] Furthermore, in the feeding direction, the angle seat valve is located in front of the diaphragm pump.

[0010] Furthermore, the feed pipe between the angle seat valve and the material tank is a rigid pipe, while the feed pipes between the angle seat valve and the diaphragm pump, and between the diaphragm pump and the material box, are flexible pipes.

[0011] Furthermore, the material bin is located in the factory's ground floor workshop, the material barrel is located upstairs, and the material supply pipe passes through the floors.

[0012] Furthermore, the liquid material is an inorganic solvent or an organic solvent.

[0013] The beneficial effects of this utility model are:

[0014] (1) The pipeline is safely shut off by using the angle seat valve and diaphragm pump to block the gravity flow and siphon channels;

[0015] (2) The diaphragm pump has a stable input material flow rate;

[0016] (3) The electromagnetic valve has a fast response. Attached Figure Description

[0025] The specific implementation of the liquid high-level feeding device of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] See appendix Figure 1 , attached Figure 1 This is a schematic diagram of the patent and does not represent an actual piping diagram. Those skilled in the art can implement this patent based on the schematic diagram.

[0027] The feeding device includes a material bucket 1, a feeding pipe, and a material box 2. The material bucket 1 is located at a higher position, and the material box 2 is located at a lower position. The feeding pipe transports liquid materials from the material bucket 1 to the material box 2. In the pesticide processing workshop, the material bucket 1 is located on the second-floor material layer, and the material box 2 is located on the first-floor workshop. The height difference makes it easier to supply materials between the three floors.

[0028] An angle seat valve 4 and a diaphragm pump 5 are installed on the feed pipe at the material box 2 on the first floor. The angle seat valve 4 is located above the diaphragm pump 5. A float switch 6 is installed in the material box 2.

[0029] Additionally, a power supply 7, an air source 8, and a solenoid valve 9 are provided. The air source 8 is connected to the angle seat valve 4 and the diaphragm pump 5 via the air pipe 12 and the solenoid valve 9. The power supply 7 is connected to the solenoid valve 9 via a float switch 6. When the material tank 2 is at a low liquid level, the float switch 6 opens the solenoid valve 9, and the air source 8 opens the angle seat valve 4 and the diaphragm pump 5, allowing the material bucket 1 to supply material to the material tank 2. When the material tank 2 is at a high liquid level, the float switch 6 closes the solenoid valve 9, and the angle seat valve 4 and the diaphragm pump 5 close, stopping the material supply.

[0030] The solenoid valve 9 is an on / off type solenoid valve 9, and the air outlet is divided into two paths that are simultaneously connected to the angle seat valve 4 and the diaphragm pump 5, so that the angle seat valve 4 and the diaphragm pump 5 open or close at the same time.

[0031] The feed pipe between the angle seat valve 4 and the material tank 1 is a rigid pipe 10, such as a stainless steel pipe. The feed pipes between the angle seat valve 4 and the diaphragm pump 5, and between the diaphragm pump 5 and the material tank 2, are flexible pipes 11, such as steel wire hoses. Due to the vibration of the diaphragm pump 5 during operation, the flexible pipe 11 can absorb the vibration and reduce the impact on the pipeline.

[0032] In addition to supplying organic solvents for pesticide production, this patent is applicable to other similar applications, including the supply of inorganic solvents and oils.

[0033] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
