Description

Technical Field

[0001] This utility model is a feeding device, belonging to the field of chemical waste material treatment. Background Technology

[0002] Chemical waste mainly refers to the leftover scraps from the production and utilization of chemical raw materials, or waste that has been contaminated and cannot be reused during the production process. These wastes include solid waste, liquid waste, and gaseous waste. When treating liquid chemical waste, specific solutions can be added for neutralization or precipitation reactions to reduce or eliminate its harmfulness. For example, alkaline waste liquids, such as sodium hydroxide and ammonia, can be neutralized with hydrochloric acid or other acidic solutions. The hydroxide ions in the alkali combine with the hydrogen ions in the acid to form water, reducing the alkalinity of the waste liquid. Therefore, in the treatment of liquid chemical waste, feeding equipment is used to add the waste liquid into a reaction tank containing a large amount of hydrochloric acid solution. This feeding equipment is mostly composed of a support frame, pipes, branch pipes, and feeding ports. The solution enters from the pipes into multiple branch pipes, which are evenly distributed over the waste liquid tank, thus uniformly feeding the chemical waste liquid into the reaction tank.

[0003] However, most existing chemical waste liquid feeding equipment uses multiple branch pipes with discharge holes on the main pipe to distribute the chemical waste liquid. Since the chemical waste liquid enters the front branch pipe first and then the tail branch pipe during feeding, the tail branch pipe can only be fed after the front branch pipe has discharged. This results in uneven distribution of the chemical waste liquid when it is fed into the reaction tank, which may lead to local overheating or undercooling during the reaction process, affecting the reaction efficiency. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a feeding device to solve the problems mentioned in the background technology. This utility model enables the device to distribute chemical waste liquid more evenly when adding it to the reaction tank, avoiding local overheating or undercooling during the reaction process and affecting the reaction efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a feeding device, including a main pipe, a feeding pipe fixedly connected to the outer wall of the main pipe, a first branch pipe fixedly connected to the outer wall of the main pipe, a second branch pipe fixedly connected to the outer wall of the main pipe, and a front-end discharge component provided at the bottom of the first branch pipe.

[0006] The front-end discharge component includes a first discharge pipe fixedly connected to the bottom of the first branch pipe, a first discharge hole opened on the outer wall of the first discharge pipe, a sealing cover slidably connected to the outer wall of the first discharge pipe, a sealing ring fixedly connected to the inner wall of the sealing cover, a connecting rod fixedly connected to the bottom of the sealing cover, and a rear-end discharge component provided at the bottom of the second branch pipe.

[0007] Furthermore, the rear discharge component includes a second discharge pipe fixedly connected to the bottom of the second branch pipe, a second discharge hole is provided on the outer wall of the second discharge pipe, and a spring is fixedly connected to the inner bottom wall of the second discharge pipe.

[0008] Furthermore, a sealing plate is fixedly connected to the top of the spring, and the outer wall of the sealing plate is slidably connected to the inner wall of the second discharge pipe.

[0009] Furthermore, an installation channel is provided on the inner bottom wall of the second discharge pipe, and an electric push rod is fixedly sleeved on the inner wall of the installation channel. A control switch button is provided on the top of the electric push rod.

[0010] Furthermore, a lifting rod is fixedly connected to the bottom of the electric push rod, and a connecting cross plate is fixedly connected to one side of the lifting rod.

[0011] Furthermore, one end of the connecting horizontal plate is fixedly connected to one end of the connecting rod, and a connecting vertical plate is fixedly connected to one side of the connecting horizontal plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. The second discharge pipe is located at the tail end of the second branch pipe. The bottom of the other ends of the second discharge pipe is the first discharge pipe. The chemical waste liquid will first fill all the first discharge pipes and then enter the interior of the second discharge pipe. The sealing plate will move downward under the gravity of the chemical waste liquid, and its bottom will press the control switch button. The electric push rod will drive all the sealing covers downward through the lifting rod and the connecting horizontal plate, thus exposing the first discharge hole. Since the sealing plate is lower than the second discharge hole when it moves downward to press the control switch button, the liquid can be discharged through the second discharge hole. Thus, the first discharge hole and the second discharge hole are used together to add the chemical waste liquid into the interior of the reaction tank. This makes the chemical waste liquid distributed more evenly when added to the reaction tank, avoiding local overheating or overcooling during the reaction process, which would affect the reaction efficiency.

[0014] 2. After the chemical waste liquid enters the second discharge pipe, the sealing plate will move downwards due to the gravity of the chemical waste liquid. At this time, it means that all the first and second discharge pipes are filled with chemical waste liquid. After the sealing plate moves downwards due to the gravity of the chemical waste liquid, its bottom will press the control switch button, and the electric push rod will start working. When the second discharge pipe and multiple first discharge pipes are filled with chemical waste liquid, the electric push rod will automatically start, thereby further meeting the working requirements of the device and bringing great convenience to the staff.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a feeding device, including a main pipe 1, a feeding pipe 2 fixedly connected to the outer wall of the main pipe 1, the feeding pipe 2 being connected to an external water pipe for transporting chemical waste liquid via a mounting flange, a first branch pipe 3 fixedly connected to the outer wall of the main pipe 1, the number of first branch pipes 3 being several, a second branch pipe 4 fixedly connected to the outer wall of the main pipe 1, and a front-end discharge component being provided at the bottom of the first branch pipe 3.

[0023] The front-end discharge component includes a first discharge pipe 5 fixedly connected to the bottom of the first branch pipe 3. The outer wall of the first discharge pipe 5 has a first discharge hole 6. A sealing cover 7 is slidably connected to the outer wall of the first discharge pipe 5. A sealing ring 8 is fixedly connected to the inner wall of the sealing cover 7. A connecting rod 9 is fixedly connected to the bottom of the sealing cover 7. The sealing cover 7 can block the first discharge hole 6, so the first discharge pipe 5 will not discharge material under the sealing of the sealing cover 7. The sealing ring 8 can improve the sealing performance of the sealing cover 7. The bottom of the second branch pipe 4 is provided with a rear-end discharge component.

[0024] The rear discharge component includes a second discharge pipe 12 fixedly connected to the bottom of the second branch pipe 4. The outer wall of the second discharge pipe 12 is provided with a second discharge hole 13. A spring 14 is fixedly connected to the inner bottom wall of the second discharge pipe 12. The second discharge pipe 12 is located at the tail end of the second branch pipe 4. The bottom of the other tail end of the second discharge pipe 12 is provided with a first discharge pipe 5. Since the second discharge pipe 12 is located at the very end of the second branch pipe 4, the chemical waste liquid will first fill all the first discharge pipes 5, and then enter the interior of the second discharge pipe 12.

[0025] A sealing plate 15 is fixedly connected to the top of the spring 14. The outer wall of the sealing plate 15 is slidably connected to the inner wall of the second discharge pipe 12. The second discharge hole 13 is located below the sealing plate 15. When a small amount of chemical waste liquid enters the interior of the second discharge pipe 12, the sealing plate 15 will not be lower than the position of the second discharge hole 13, and thus the second discharge hole 13 cannot discharge. After a large amount of chemical waste liquid enters the interior of the second discharge pipe 12, the sealing plate 15 will move downward due to the gravity of the chemical waste liquid. At this time, it means that all the first discharge pipes 5 and the second discharge pipe 12 are filled with chemical waste liquid.

[0026] The inner bottom wall of the second discharge pipe 12 is provided with an installation channel 16. An electric push rod 17 is fixedly sleeved on the inner wall of the installation channel 16. A control switch button 18 is provided on the top of the electric push rod 17. After the sealing plate 15 is moved downward by the gravity of the chemical waste liquid, its bottom will press against the control switch button 18. The electric push rod 17 and the control switch button 18 are existing devices and will not be explained in detail here. After the control switch button 18 is pressed, the electric push rod 17 will start to work and the bottom of the electric push rod 17 will extend.

[0027] The bottom of the electric push rod 17 is fixedly connected to the lifting rod 19, and one side of the lifting rod 19 is fixedly connected to the connecting horizontal plate 10. One end of the electric push rod 17 will drive the lifting rod 19 and the connecting horizontal plate 10 to move downward.

[0028] One end of the connecting horizontal plate 10 is fixedly connected to one end of the connecting rod 9, and a connecting vertical plate 11 is fixedly connected to one side of the connecting horizontal plate 10. This allows all the sealing covers 7 to move downwards, thus exposing the first discharge hole 6. When the sealing plate 15 moves downwards and presses the control switch button 18, its position is lower than the second discharge hole 13, allowing the liquid to be discharged through the second discharge hole 13. This enables the first discharge hole 6 and the second discharge hole 13 to be used together to add the chemical waste liquid into the interior of the reaction tank.

[0029] Working principle: First, the feeding pipe 2 is connected to the water pipe for transporting chemical waste liquid through the installation flange. The chemical waste liquid will first enter the main pipe 1, and then be diverted to the second branch pipe 4 and multiple first branch pipes 3. Since the second discharge pipe 12 is located at the end of the second branch pipe 4, and the bottom of the other ends of the second discharge pipe 12 is set with the first discharge pipe 5, the chemical waste liquid will first fill all the first discharge pipes 5, and finally enter the interior of the second discharge pipe 12.

[0030] Secondly, after the chemical waste liquid enters the second discharge pipe 12, the sealing plate 15 will move downward due to the gravity of the chemical waste liquid. At this time, it means that all the first discharge pipes 5 and the second discharge pipe 12 are filled with chemical waste liquid. After the sealing plate 15 moves downward due to the gravity of the chemical waste liquid, its bottom will press the control switch button 18, and the electric push rod 17 will start working.

[0031] Finally, the bottom of the electric push rod 17 extends, causing the lifting rod 19 and the connecting horizontal plate 10 to move downwards, which in turn causes all the sealing covers 7 to move downwards, thus exposing the first discharge hole 6. Since the sealing plate 15 moves downwards and presses the control switch button 18, its position is lower than the second discharge hole 13, so the liquid can be discharged through the second discharge hole 13, thus realizing that the first discharge hole 6 and the second discharge hole 13 together add the chemical waste liquid into the interior of the reaction tank.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
