Description

Technical Field

[0001] This invention relates to the field of carbon source production technology, specifically to a composite carbon source production device. Background Technology

[0002] As a key nutrient in the denitrification process of wastewater treatment, composite carbon sources play an irreplaceable role in improving the nitrogen removal efficiency of wastewater. They are carefully composed of a variety of carbon source substances, which can provide sufficient energy and material basis for the growth and metabolism of microorganisms, thereby effectively promoting the removal of nitrogen-containing pollutants in wastewater. This is of great significance for maintaining the ecological balance of water bodies and ensuring the sustainable use of water resources. In order to reduce costs or improve performance, composite carbon sources are often produced by mixing solid (inexpensive) and liquid (efficient) raw materials, such as molasses (solid waste) and sodium acetate (liquid).

[0003] In the production of composite carbon sources, solid raw materials are prone to caking during storage and transportation when added to carbon source production equipment. Caking hinders the smooth flow of raw materials into the reaction unit, reducing production efficiency. Current production equipment often uses feed pipes directly connected to the feeding equipment, lacking an effective pre-treatment mechanism for caking raw materials. This typically requires manual pre-crushing of the caking materials, which is labor-intensive, inefficient, and detrimental to the equipment's practicality. Therefore, a composite carbon source production device needs to be designed to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a composite carbon source production device to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this application to solve its technical problem is: a composite carbon source production device, including a tank, an end cover and a feed hopper, wherein the end cover is fixed to the tank by bolts, the feed hopper is fixed to one side of the end cover, and the device also includes a mounting frame, wherein the mounting frame is fixed to the upper end of the end cover by bolts, a servo motor is fixed to the upper end of the mounting frame, and a worm gear is fixed to the output end of the servo motor through a coupling; The crushing assembly includes a crushing box bolted to the upper end of the feed hopper. Two crushing rollers are rotatably mounted inside the crushing box. One end of each crushing roller passes through the crushing box and is fixed with a gear, which is suitable for crushing agglomerated solid raw materials.

[0006] Furthermore, positioning plates are fixed on both sides of the upper end of the end cap, and an installation shaft is rotatably mounted on the upper end of the positioning plate. The installation shaft is fixed to one of the crushing rollers through a coupling. A worm gear is fixed in the middle of the installation shaft. The worm gear is meshed with the worm. The servo motor drives the worm to rotate, thereby driving the worm gear to rotate, which in turn drives one of the crushing rollers to rotate. The two gears are meshed with each other, so that the two crushing rollers rotate relative to each other and squeeze the agglomerated raw materials.

[0007] Furthermore, the upper end of the crushing box is fixed with a connecting cover by bolts, which is suitable for connecting an external feeding assembly, and the front end of the crushing box is provided with a first protective cover, which is suitable for protecting the two gears.

[0008] Furthermore, a second protective cover is provided at the upper end of the end cap, which is suitable for protecting the worm gear.

[0009] Furthermore, the lower end of the worm gear is fixed to a stirring shaft via a coupling. The stirring shaft is located inside the tank and has stirring blades fixed on it, which is suitable for mixing and stirring the raw materials.

[0010] Furthermore, a sealing ring is provided at the connection between the tank body and the end cap.

[0011] Furthermore, a plurality of feed pipes are provided on one side of the upper end of the end cap, which is suitable for adding liquid raw materials, and a discharge control valve is provided at the discharge port at the lower end of the tank.

[0012] Furthermore, the outer wall of the tank is fixed with multiple support legs by bolts.

[0013] By adopting the above technical solution, the problem of some production devices having their feed pipes directly connected to the feeding equipment, lacking an effective pre-treatment mechanism for agglomerated raw materials, and usually requiring manual pre-crushing of agglomerated raw materials has been solved.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the carbon source production device, The crushing assembly features two relatively rotating crushing rollers that automatically crush agglomerated solid raw materials without the need for manual pre-crushing, significantly reducing labor intensity and improving production efficiency. Simultaneously, a servo motor drives a worm gear, which in turn drives the crushing rollers and the stirring shaft to rotate at the same time. The stirring shaft is equipped with stirring blades, which can mix and stir the raw materials in the tank while crushing them, ensuring that the solid and liquid raw materials are fully contacted and blended, thereby improving reaction efficiency and product quality.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-8This invention provides a technical solution: a composite carbon source production device, comprising a tank 1, an end cap 2, and a feed hopper 8. The tank 1 is cylindrical in shape, which facilitates thorough mixing and reaction of raw materials internally, ensures structural strength, and is easy to manufacture and install. The end cap 2 has a diameter that matches the opening diameter of the tank 1 and is tightly fixed to the top opening of the tank 1 with bolts. A sealing ring 18 is provided at the connection between the tank 1 and the end cap 2. The sealing ring 18 is typically made of annular rubber, and its inner diameter fits tightly with the outer diameter of the opening edge of the tank 1. The outer diameter is slightly larger than the inner diameter of the connection part of the end cap 2, ensuring effective sealing after tightening the bolts, preventing raw material leakage during production, and ensuring a clean production environment and production safety.

[0019] The feed hopper 8 is a funnel-shaped structure, wider at the top and narrower at the bottom, fixed to one side of the end cap 2. Its larger upper opening facilitates the receipt of various raw materials, while the lower opening is aligned with the inside of the tank 1, allowing the raw materials to fall smoothly in. Multiple feed pipes 19 are provided on one side of the upper end of the end cap 2. These feed pipes 19 are evenly spaced and are typically vertical tubular structures. Their lower ends penetrate the end cap 2 and extend to a certain depth inside the tank 1 for adding liquid raw materials. In actual production, operators can precisely add various liquid raw materials through different feed pipes 19 according to the production formula, ensuring that the composition of the composite carbon source meets the requirements. A discharge control valve 20 is provided at the discharge port at the lower end of the tank 1. The discharge port is located at the center of the bottom of the tank 1, and the discharge control valve 20 is installed at the discharge port to control the discharge of the finished composite carbon source.

[0020] Mounting bracket 3 is bolted to the upper end of end cap 2. Mounting bracket 3 has a frame-like structure, and its shape and size are designed according to the installation requirements of servo motor 4 and other related components, serving to stably support and fix servo motor 4. Servo motor 4 is fixed to the upper end of mounting bracket 3. The output shaft of servo motor 4 is vertically downward and tightly connected to the upper end of worm gear 5 via a coupling. Worm gear 5 is a slender rod-like structure, and its lower end is fixed to stirring shaft 6 via a coupling. Stirring shaft 6 is cylindrical, located at the internal central axis of tank 1, and coincides with the axis of tank 1. Stirring blades 7 are fixed on stirring shaft 6. Stirring blades 7 are paddle-shaped and evenly distributed along the length of stirring shaft 6. When servo motor 4 is started, it drives worm gear 5 to rotate, which in turn drives stirring shaft 6 to rotate. Stirring blades 7 rotate accordingly, mixing and stirring the raw materials in tank 1, ensuring full contact and fusion of solid and liquid raw materials, promoting the reaction, and ensuring the uniformity of the composite carbon source.

[0021] The crushing assembly includes a crushing box 9 bolted to the upper part of the feed hopper 8. The crushing box 9 is a rectangular box structure, its length and width designed according to the size of the crushing rollers 10 and the installation space, with a moderate height to facilitate the entry and exit of raw materials. A connecting cover 15 is bolted to the upper end of the crushing box 9. The connecting cover 15 is flared, wider at the bottom and narrower at the top. The smaller end is used to connect to an external feeding assembly, and the larger end is tightly connected to the feed inlet of the crushing box 9, allowing solid raw materials conveyed by the external feeding equipment to smoothly enter the crushing box 9. Two crushing rollers 10 are rotatably mounted inside the crushing box 9. The two crushing rollers 10 are cylindrical, placed parallel to each other, and their axes are at the same horizontal level. Their length is slightly less than the internal width of the crushing box 9 to ensure that the raw materials are fully crushed during rotation. One end of each crushing roller 10 penetrates the side wall of the crushing box 9 and is fixed with a gear 11. The gears 11 are standard cylindrical gears, and the two gears 11 mesh with each other to ensure that the two crushing rollers 10 can rotate relative to each other.

[0022] Positioning plates 12 are fixed on both sides of the upper end of the end cover 2. The positioning plates 12 are rectangular plate structures and are vertically fixed on the end cover 2. An installation shaft 13 is rotatably mounted on the upper end of the positioning plate 12. The installation shaft 13 is cylindrical and its axis is parallel to the axis of the crushing roller 10. One end of the installation shaft 13 is fixed to a crushing roller 10 through a coupling. A worm gear 14 is fixed in the middle of the installation shaft 13. The worm gear 14 is disc-shaped and its gear ring is meshed with the worm 5. When the servo motor 4 drives the worm 5 to rotate, the worm 5 rotates, which in turn drives the meshing worm gear 14 to rotate. The worm gear 14 drives a crushing roller 10 to rotate through the installation shaft 13. Since the two gears 11 are meshed, the other crushing roller 10 will rotate relative to it, thereby realizing the function of crushing agglomerated raw materials.

[0023] Working Principle: Before producing the composite carbon source, the external feeding equipment is connected to the connecting cover 15, and solid and liquid raw materials are prepared. The servo motor 4 is started, driving the worm gear 5 to rotate. As the worm gear 5 rotates, it drives the meshing worm wheel 14 to rotate. The worm wheel 14 drives a crushing roller 10 to rotate via the mounting shaft 13. Because the two gears 11 are meshed, the other crushing roller 10 will rotate relative to it. At this time, the potentially agglomerated solid raw material is conveyed to the crushing box 9 through the connecting cover 15 via the external feeding equipment. Under the squeezing action of the two relatively rotating crushing rollers 10, the agglomerated solid raw material is crushed, and the crushed material falls into the tank 1 through the feed hopper 8.

[0024] Meanwhile, according to the production formula, the corresponding liquid raw materials are added to the tank 1 through the feed pipe 19. As the worm gear 5 continues to rotate, the stirring shaft 6 and stirring blades 7 mix and stir the solid and liquid raw materials falling into the tank 1, so that the raw materials react fully to generate a composite carbon source. When production is completed, the servo motor 4 is turned off and the discharge control valve 20 is opened, and the composite carbon source is discharged from the discharge port at the lower end of the tank 1.

[0025] Throughout the production process, a first protective cover 16 installed at the front end of the crushing chamber 9 protects the two gears 11. The first protective cover 16 is installed at the front end of the crushing chamber 9, covering the two gears 11 to prevent operators from accidentally touching the gears 11 and avoiding safety accidents. A second protective cover 17 installed on the upper end of the end cover 2 protects the worm gear 14. The second protective cover 17 is installed on the end cover 2, covering the worm gear 14, ensuring the safety of operators, and also reducing the entry of dust and other impurities into the transmission components, extending the service life of the equipment. Multiple support legs 21 are bolted to the outer wall of the tank body 1. The support legs 21 are square columnar structures, evenly distributed around the tank body 1, used to support the entire device, ensuring stable placement and smooth operation of the production process.

[0026] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
