Description

Technical Field

[0001] This utility model belongs to the field of phosmet additive dosing technology, specifically referring to a phosmet additive dosing device. Background Technology

[0002] Phosphine is an organophosphorus insecticide with low toxicity to humans and livestock, and it is effective against a variety of pests. In the production process of phosphine, adjuvants need to be added in order to adjust the properties and characteristics of the product, so an adjuvant addition device is required.

[0003] Existing phosmet additive dosing devices use direct dosing, which relies entirely on instantaneous flow meters for control. The dosage is directly affected by fluctuations in the upstream feed pump and changes in pipeline pressure. This point-to-point mode lacks a buffer unit; any minute fluctuations are transmitted to the main reaction without attenuation, leading to instability in the dosing process, deviations between the actual dosage and the set value, and severely impacting process consistency. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide an additive dosing device for phosmet, so as to at least partially solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model is as follows: A device for adding phosmet additive is proposed, comprising: a buffer weir mechanism, including at least two stacked addition pools, each with a temporary storage area at the bottom; after the temporary storage area of ​​any addition pool is filled, the additive flows to the next addition pool at a lower position; an immersion addition component, including an injection pipe disposed below the addition pool, the bottom end of the injection pipe being below the liquid surface, and a diversion pipe being disposed at the bottom end of the injection pipe; wherein, the outer sidewalls of the addition pools are fixedly connected to delivery pipes, and the bottom end of the delivery pipes extends into the interior of the temporary storage area, and the axial direction of the diversion pipe opening is perpendicular to the tangential direction of the stirring direction.

[0006] Furthermore, the additive dosing device for fenthion also includes a tank, with the dosing pool located on the upper side inside the tank. A feed pipe is provided at the top of the outside of the tank, and the tops of the delivery pipe and injection pipe outside the bottom dosing pool are detachably connected.

[0007] Furthermore, a stirring area is provided on the lower side of the inside of the tank, and a drive box is provided at the top of the inside of the stirring area. A stirring rod is rotatably connected to the lower outside of the drive box, and the diversion pipe is located at the edge of the stirring blade of the stirring rod.

[0008] Furthermore, the diverter tube is T-shaped, and the opening of the diverter tube faces the axis of rotation of the stirring rod.

[0009] Furthermore, the tail end of the feed pipe extends into the temporary storage area in the uppermost feeding pool. Beneficial effects

[0010] By using multiple stacked dosing tanks, the temporary storage area of ​​the dosing tanks can act as a barrier before the liquid additive is added, forming a weir structure. This transforms the direct, intermittent, and instantaneous dosing process into a continuous, buffered, and stable additive addition method. Furthermore, the bottom end of the delivery pipe is submerged below the liquid surface in the temporary storage area, preventing splashing during additive addition and delivery. The distributor pipe is positioned within the mixing zone at the position of the stirring blade, accelerating the rapid and uniform diffusion of the added additive after it enters the mixing zone.

[0013] The accompanying drawings are provided to further understand the embodiments and form part of the specification. They are used together with the embodiments for explanation and do not constitute a limitation on the embodiments. Detailed Implementation

[0014] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0015] As mentioned earlier, the existing technology uses direct injection, which relies entirely on instantaneous flow meters for control. The injection rate is directly affected by factors such as fluctuations in the upstream feed pump and changes in pipeline pressure. This point-to-point mode lacks a buffer unit, and any minute fluctuations are transmitted to the reaction body without attenuation, leading to instability in the injection process, deviations between the actual dosage and the set value, and seriously affecting the consistency of the process.

[0016] To address this issue, this invention provides a device for adding phosmet, an additive. This device uses multiple stacked addition pools 101, where the liquid additive is blocked by a temporary storage area 102 before being added, forming a weir structure. This transforms the direct, intermittent, and instantaneous addition process into a continuous, buffered, and stable addition method. Furthermore, the bottom end of the delivery pipe 3 is submerged below the liquid surface in the temporary storage area 102, preventing splashing during additive addition and delivery. The diversion pipe 202 is positioned within the stirring zone 6 at the position of the stirring blade of the stirring rod 8, accelerating the rapid and uniform diffusion of the added additive after it enters the stirring zone 6.

[0017] like Figures 1-5 As shown in the present invention, an embodiment of the present invention provides a dosing device, particularly a dosing device for phosmet, comprising a buffer weir mechanism 1, an immersion dosing component 2, and a tank 4. The tank 4 is divided into upper and lower layers. The upper tank 4 contains a dosing pool 101. The buffer weir mechanism 1 includes multiple stacked dosing pools 101 disposed on the upper side inside the tank 4. Liquid additives such as xylene, alkylphenol polyoxyethylene ether, and castor oil polyoxyethylene ether are added through the uppermost dosing pool 101. Each dosing pool 101 has a temporary storage area 102 at its bottom, with a depth of approximately one-sixth of the pool depth. The temporary storage area 102 is used to temporarily store the additives added into the dosing pool 101 and forms a weir structure, transforming instantaneous, discontinuous dosing into buffered, indirect, and continuous dosing.

[0018] A delivery pipe 3 is fixedly connected to the outer side wall of each delivery pool 101. The connection position of the delivery pipe 3 is the depth of the temporary storage area 102. The bottom end of each delivery pipe 3 extends into the temporary storage area 102 inside the next lower delivery pool 101. The extension of the delivery pipe 3 into the temporary storage area 102 can prevent splashing during the addition of the additive.

[0019] The lower half of the tank 4 forms a stirring zone 6 for the processing of phosmet. An immersion dosing device 2 is installed inside the stirring zone 6. The immersion dosing device 2 includes a dosing pipe 3 connected to the lowest dosing tank 101, with a detachable injection pipe 201 connected below it. The bottom end of the injection pipe 201 extends below the surface of the phosmet mixture in the stirring zone 6, and a diversion pipe 202 is connected to the bottom end of the injection pipe 201. The diversion pipe 202... Figures 3-5 As shown, there are two pipe openings. The overall shape of the split pipe 202 is T-shaped. The axial direction of the pipe opening of the split pipe 202 is perpendicular to the direction of the tangent of the turbulent rotation generated by the stirring in the stirring zone 6. This can prevent the turbulence generated by the stirring from affecting the additive flowing out of the split pipe 202.

[0020] A drive box 7 is installed at the top of the mixing zone 6. Inside the drive box 7 are two meshing gears. One gear is driven by a motor inside the tank 4 where the dispensing pool 101 is installed. The other gear is fixedly connected to the top of the shaft of the stirring rod 8 inside the mixing zone 6. The diversion pipe 202 is located at the edge of the stirring blade of the stirring rod 8 inside the mixing zone 6, which facilitates the turbulence generated by the stirring rod 8 and allows the additive flowing out from the diversion pipe 202 to diffuse rapidly within the mixing zone 6. A feed pipe 5 is fixedly connected to the top of the tank 4. The feed pipe 5 is connected to a water pump installed on the tank 4 and pumps liquid additives into the dispensing pool 101 inside the tank 4. The feed pipe 5 extends into the temporary storage area 102 inside the uppermost dispensing pool 101.

[0021] In summary, this invention, through multiple stacked dosing pools 101, forms a weir structure by blocking the liquid additive in the temporary storage area 102 before it is added. This transforms the direct, intermittent, and instantaneous addition process into a continuous, buffered, and stable additive addition method. Furthermore, the bottom end of the delivery pipe 3 is submerged below the liquid surface in the temporary storage area 102, preventing splashing during additive addition and delivery. The diversion pipe 202 is positioned within the stirring zone 6 at the position of the stirring blade of the stirring rod 8, accelerating the rapid and uniform diffusion of the added additive after it enters the stirring zone 6.

In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit, such design should fall within the scope of protection.
