Description

Technical Field

[0001] This utility model belongs to the field of solid-liquid batching, and more specifically, this utility model relates to a batching device. Background Technology

[0002] In solid-liquid batching processes, solid materials need to be dissolved in a liquid. Currently used batching equipment mainly consists of open-top mixing tanks with stirring blades that have a scraping function. When the solid materials used are hygroscopic and the liquid is a highly acidic solution, large lumps are easily formed, resulting in very slow dissolution or even no dissolution. This leads to particle residue in the resulting mother liquor, preventing the achievement of the predetermined mother liquor concentration and affecting production stability. To ensure the uniformity of materials in the liquid and avoid residue, the stirring blades easily generate significant noise pollution when scraping, while also increasing the volatilization of acidic gases in the solution, polluting the surrounding air, harming production personnel, and resulting in poor production conditions. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a dispensing device that offers a fast and effective dispensing method while also preventing odor volatilization.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a batching device, including a batching box, the bottom of which is provided with an inclined smooth bottom plate, the top of which is provided with a feed inlet and an exhaust outlet at both ends, the side of the batching box near the feed inlet is provided with a liquid inlet pipe and a circulating liquid inlet pipe from high to low, the side of the batching box near the exhaust outlet is provided with a circulating liquid outlet and a discharge outlet from high to low, and an air inlet pipe is also provided inside the batching box. The air inlet pipe is L-shaped and consists of two sides, one side of which is attached to the smooth bottom plate and has multiple air outlets.

[0005] This utility model discloses a batching device, wherein the inclination angle of the smooth bottom plate is 30-60°.

[0006] This utility model discloses a dispensing device, in which a baffle is provided inside the dispensing box. The baffle is a louvered fan structure, and the main shaft can be rotated to open or close the baffle. The fan surface of the louvered fan has multiple small holes, and the height of the small holes is higher than the circulating liquid inlet pipe.

[0007] This utility model discloses a batching device, wherein multiple air inlet pipes can be provided.

[0008] This utility model discloses a batching device, wherein the air pressure at the air outlet is 0.4-0.5MPa.

[0009] This utility model discloses a batching device, wherein the circulating liquid inlet pipe is a multi-pipe liquid inlet.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] 1. Because the bottom of the tank of this batching device is a smooth, sloping bottom plate, the material is discharged under liquid impact, and there is basically no liquid remaining in the tank.

[0012] 2. The entire process of this batching device is carried out inside a sealed box. After the material is unloaded, most of the gas is discharged from the exhaust port and treated by an external exhaust gas treatment device, thus preventing the odor from evaporating.

[0013] 3. This batching device uses liquid and gas as power sources for batching, eliminating the need for a mixer, making the batching process more environmentally friendly and quieter.

[0014] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0021] The following description, with reference to the accompanying drawings, further details the specific implementation methods of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the function and working principle of each part, the manufacturing process, and the operation and use methods, so as to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the utility model concept and technical solution.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4The batching device shown includes a batching box with an inclined smooth bottom plate at the bottom. The top of the batching box has an inlet 2 and an outlet 7 at each end. A liquid inlet pipe 3 and a circulating liquid inlet pipe 4 are arranged from high to low on the side of the batching box near the inlet 2. A circulating liquid outlet 9 and a discharge outlet 8 are arranged from high to low on the side of the batching box near the outlet 7. An air inlet pipe 5 is also provided inside the batching box. The air inlet pipe 5 is L-shaped and consists of two sides, one of which is in contact with the smooth bottom plate and has multiple air outlets 1. The inclination angle of the smooth bottom plate is 30-60°. A baffle 6 is also provided inside the batching box. The baffle 6 has a louvered structure and can be opened and closed by rotating the main shaft. The louvered surface has multiple small holes, and the height of the small holes is higher than that of the circulating liquid inlet pipe 4. Multiple air inlet pipes 5 can be provided. The air pressure of the outlet 1 is 0.4-0.5 MPa. The circulating liquid inlet pipe 4 is a multi-pipe liquid inlet.

[0023] Working principle and method

[0024] 1. First, use a hydraulic lift truck to lift the material stored in the ton bag and place it at the inlet 2. Open the bottom discharge port of the ton bag and put the material into the batching box.

[0025] 2. Adjust the baffle 6 to the closed position, open the liquid inlet pipe 3 to start liquid inlet, and at the same time open the air inlet pipe 5 to start air inlet. Air will be released from the air outlet 1 at the bottom of the air inlet pipe to float the material at the bottom. When the solution entering the mixing tank reaches the predetermined value, close the valve of the liquid inlet pipe 3.

[0026] 3. When the liquid level in the mixing tank reaches the height of the small hole on the louver of the baffle 6, the liquid enters the other side of the baffle through the small hole. The pump then pumps the liquid from the circulation outlet 9 to the circulation inlet pipe 4, starting the circulation and impacting the material pile, causing it to spread to the bottom plate and surrounding areas. The liquid and gas impact forces accelerate the dissolution rate of the material.

[0027] 4. After the material is completely dissolved, close the air inlet pipe 5, open the outlet 8, and adjust the baffle 6 to the open position. The dissolved liquid will be discharged from the outlet 8.

[0028] 5. After all the liquid has been discharged, open the exhaust port 7 to send the gas generated during the mixing process to the waste gas treatment device.

[0029] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
