Description

Technical Field

[0001] The utility model belongs to the technical field of coal washing, and particularly relates to a fast adjustable chemical feeder. Background Art

[0002] The chemical feeder in a coal washing plant is one of the important devices in the coal washing process. Its main function is to accurately and evenly add various chemicals such as flocculants and coagulants to treatment links such as coal slime water. Through a fast adjustable chemical feeder, the addition amount and addition speed of the chemicals can be precisely controlled, thereby optimizing the coal washing process and improving the coal washing effect and efficiency. However, when the flow rate of the chemicals is too fast during the chemical feeding process, there may be a problem that different chemicals do not have enough time to mix in the conveying pipe, and after entering the coal washing tank, there may be uneven distribution of the chemicals in the coal washing tank due to uneven mixing. Summary of the Utility Model

[0003] The utility model provides a fast adjustable chemical feeder, which can, on the one hand, improve the mixing effect of the liquid medicine for mixing, and on the other hand, avoid the influence of the chemical flow rate on the chemical mixing effect.

[0004] The utility model provides the following technical solution: a fast adjustable chemical feeder, including a fast adjustable chemical feeder body. A first conveying pipe and a second conveying pipe are installed on the fast adjustable chemical feeder body, and a mixing pipe is installed at the bottom of the first conveying pipe and the second conveying pipe. The bottoms of the first conveying pipe and the second conveying pipe penetrate into the interior of the mixing pipe. The lower end of the first conveying pipe is fixedly communicated with a first inclined guiding pipe, and the lower end of the second conveying pipe is fixedly communicated with a second inclined guiding pipe. The bottom of the second inclined guiding pipe penetrates to one side of the first inclined guiding pipe. The first inclined guiding pipe is communicated with the second inclined guiding pipe. A plurality of connecting inclined plates are fixedly connected inside the mixing pipe, and a plurality of rotating shafts are rotatably connected to the connecting inclined plates. A plurality of stirring blades are fixedly connected to the outside of the rotating shafts.

[0005] Wherein, a sealing ring is fixedly connected at the connection part of the second inclined guiding pipe and the first inclined guiding pipe.

[0006] Wherein, a plurality of inclined plates are rotatably connected to the inner side of the first inclined guiding pipe through torsion spring rotating shafts, and the positions of the inclined plates correspond to the positions of the lower ends of the second inclined guiding pipes.

[0007] Wherein, an elastic connection wall is fixedly connected between the end of the inclined plate and one side of the first inclined guiding pipe.

[0008] Wherein, a guiding inclined plate is arranged below the connecting inclined plate, and one end of the guiding inclined plate is fixedly connected to the inner side of the mixing pipe.

[0009] Among them, a threaded connection pipe is fixedly connected to the bottom of the mixing pipe.

[0010] The beneficial effects of the present utility model are as follows: With the mutual cooperation of the first inclined guide pipe, the second inclined guide pipe, the inclined plate, the rotating shaft, and the stirring blades, a primary mixing can be completed in the first inclined guide pipe before the medicament enters the mixing pipe. Moreover, the faster the liquid flows in the first inclined guide pipe and the mixing pipe, the higher the mixing efficiency. This can effectively avoid the problem that the flow rate affects the mixing efficiency due to insufficient mixing time caused by too fast a flow rate during the mixing of the medicament. And by means of the impact of the medicament in the first inclined guide pipe and the medicament in the second inclined guide pipe, as well as with the assistance of the inclined plate for the mixing of the medicament, it can help improve the mixing effect of the medicament. At the same time, the scouring force generated when the medicament flows downward in the mixing pipe can help assist the mixing effect of the medicament in the mixing pipe.

[0017] Please refer to Figures 1 - 4, the present utility model provides the following technical solutions: A quick-adjustable chemical dosing machine, comprising a quick-adjustable chemical dosing machine body 1, a first delivery pipe 11 and a second delivery pipe 12 are installed on the quick-adjustable chemical dosing machine body 1, and a mixing pipe 2 is installed at the bottom of the first delivery pipe 11 and the second delivery pipe 12. The bottoms of the first delivery pipe 11 and the second delivery pipe 12 penetrate into the interior of the mixing pipe 2. The lower end of the first delivery pipe 11 is fixedly communicated with a first inclined guiding pipe 111, and the lower end of the second delivery pipe 12 is fixedly communicated with a second inclined guiding pipe 121. The bottom of the second inclined guiding pipe 121 penetrates to one side of the first inclined guiding pipe 111, and the first inclined guiding pipe 111 is communicated with the second inclined guiding pipe 121. A plurality of connecting inclined plates 21 are fixedly connected inside the mixing pipe 2, and a plurality of rotating shafts 22 are rotatably connected to the connecting inclined plates 21. A plurality of stirring blades 221 are fixedly connected to the outer side of the rotating shaft 22.

[0018] In this implementation scheme: The main body of the quick-adjustable chemical feeder 1 is the main body of the entire chemical feeder. The first delivery pipe 11 and the second delivery pipe 12 installed on the main body of the quick-adjustable chemical feeder 1 are both used to deliver the liquid medicine in the medicine tank of the main body of the quick-adjustable chemical feeder 1. The mixing pipe 2 installed at the bottom of the first delivery pipe 11 and the second delivery pipe 12 is used to provide a channel for mixing and delivering the liquid medicine. The first inclined guide pipe 111 installed at the bottom of the first delivery pipe 11 is used to guide the liquid medicine in the first delivery pipe 11. The second inclined guide pipe 121 installed at the bottom of the second delivery pipe 12 is used to guide the liquid medicine in the second delivery pipe 12 when it enters the mixing pipe 2. And the medicine in the first delivery pipe 11 and the medicine in the second delivery pipe 12 can be conveyed into the interior of the mixing pipe 2 along an inclined flow path during the process of entering the mixing pipe 2 under the guidance of the first inclined guide pipe 111 and the second inclined guide pipe 121 respectively. And during the process that the liquid medicine in the first delivery pipe 11 enters the mixing pipe 2 through the first inclined guide pipe 111, it can be premixed with the liquid medicine in the second delivery pipe 12 that enters the mixing pipe 2 through the second inclined guide pipe 121. And when the medicine in the second inclined guide pipe 121 rushes into the first inclined guide pipe 111, the downward impact force of the liquid medicine in the second inclined guide pipe 121 can be used to assist the good mixing of the liquid medicine in the first inclined guide pipe 111 and the medicine in the second inclined guide pipe 121, which helps to improve the mixing uniformity of the medicine in the first delivery pipe 11 and the medicine in the second delivery pipe 12. The connecting inclined plate 21 located in the mixing pipe 2 is used to provide a connecting carrier for a plurality of rotating shafts 22. The rotating shafts 22, in cooperation with the stirring blades 221, form a component for stirring the liquid medicine in the mixing pipe 2 during the downward flow. When the liquid medicine in the first inclined guide pipe 111 and the second inclined guide pipe 121 enters the mixing pipe 2, during the process that the medicine flows downward in the mixing pipe 2, the downward scouring force of the liquid can be used to drive the rotating shafts 22 and the stirring blades 221 to rotate. And during the rotation of the stirring blades 221, the liquid medicine in the mixing pipe 2 can be stirred, further assisting the mixing effect of the medicines during the delivery of the liquid medicine. And the faster the flow rate of the liquid medicine in the mixing pipe 2, the greater the scouring force on the stirring blades 221, and at this time the stirring blades 221 rotate faster.

[0019] A sealing ring 122 is fixedly connected to the connection part between the second inclined guide pipe 121 and the first inclined guide pipe 111; the sealing ring 122 is used to improve the sealing effect at the connection part between the second inclined guide pipe 121 and the first inclined guide pipe 111.

[0020] The inner side of the first inclined guide tube 111 is rotatably connected to a plurality of inclined plates 112 through a torsion spring shaft, and the position of the inclined plate 112 corresponds to the position of the lower end portion of the second inclined guide tube 121; when the medicine in the second inclined guide tube 121 flushes and flows into the first inclined guide tube 111, it can provide a downward pressure force on the inclined plate 112. At this time, the inclined plate 112 flips downward, and at the same time, it can drive the liquid in the first inclined guide tube 111 to shake during the downward flipping process, which helps to further enhance the mixing effect of the liquid in the first inclined guide tube 111.

[0021] An elastic connecting wall 113 is fixedly connected between the end of the inclined plate 112 and one side of the first inclined guide tube 111 ; the elastic connecting wall 113 is used to provide a carrier for connecting the end of the inclined plate 112 and the first inclined guide tube 111 .

[0022] A guide inclined plate 23 is provided below the connecting inclined plate 21, and one end of the guide inclined plate 23 is fixedly connected to the inner side of the mixing tube 2; wherein the guide inclined plate 23 plays a guiding role.

[0023] A threaded connection pipe 24 is fixedly connected to the bottom of the mixing pipe 2; wherein the threaded connection pipe 24 is used to connect with an external pipe body.

[0024] Working principle and usage process of the present utility model: When it is necessary to add chemicals to the coal washing tank during the coal washing process, the chemicals can be added to the coal washing tank by starting the operation of the quick-adjustable chemical dosing machine body 1. At this time, the chemicals in the two chemical tanks in the quick-adjustable chemical dosing machine body 1 enter the mixing pipe 2 through the first delivery pipe 11 and the second delivery pipe 12. And before the chemicals in the first delivery pipe 11 and the chemicals in the second delivery pipe 12 enter the mixing pipe 2, they are pre-mixed in the first inclined guide pipe 111. At this time, when the chemicals in the second inclined guide pipe 121 rush into the first inclined guide pipe 111, on the one hand, the downward impact force of the liquid medicine in the second inclined guide pipe 121 can be used to assist the liquid medicine in the first inclined guide pipe 111 to mix well with the chemicals in the second inclined guide pipe 121, which helps to improve the mixing uniformity of the chemicals in the first delivery pipe 11 and the chemicals in the second delivery pipe 12. On the other hand, when the chemicals in the second inclined guide pipe 121 wash and flow into the first inclined guide pipe 111, a downward pressing force can be provided to the inclined plate 112. At this time, the inclined plate 112 turns downward, and at the same time, it can drive the liquid in the first inclined guide pipe 111 to shake during the downward turning process, which helps to further improve the mixing effect of the liquid in the first inclined guide pipe 111. When the liquid medicine in the first inclined guide pipe 111 enters the mixing pipe 2, during the downward flow of the chemicals in the mixing pipe 2, the downward scouring force of the liquid can be used to drive the rotating shaft 22 and the stirring blades 221 to rotate. And during the rotation of the stirring blades 221, the liquid medicine in the mixing pipe 2 can be stirred, further assisting the mixing effect of the chemicals during the transportation of the liquid medicine. Finally, the chemicals enter the external pipeline through the threaded connection pipe 24 and enter the coal washing tank through the external pipeline.
