Description

Technical Field

[0001] This invention relates to the field of composite carbon source manufacturing technology, and more specifically to a composite carbon source manufacturing apparatus and method. Background Technology

[0002] Composite carbon sources are efficient and low-cost external carbon sources for wastewater treatment, widely used in the biochemical treatment processes of municipal sewage and industrial wastewater. They can effectively improve the efficiency of microbial nitrogen and phosphorus removal, and enhance wastewater purification. The industrial production of composite carbon sources requires multiple processes, including crushing, mixing, and fusing, to ensure thorough reaction of various raw materials and form a composite carbon source product with uniform composition and high stability.

[0003] For example, the prior art disclosure number CN121343754A discloses a composite carbon source and its preparation method and special device. This prior art uses starch-metabolizing microorganisms and related enzymes to perform solid-liquid separation by adding them, employing a sequential batch process and a filtration device, and using differentiated ultrasound to enhance the production and solid-liquid separation. This achieves a dual improvement in the production efficiency and solid-liquid separation effect of the composite carbon source, reduces material and energy consumption, is simple to operate, has low cost, and is less corrosive.

[0004] However, traditional composite carbon source manufacturing equipment has a limited structure and function, mostly only possessing simple stirring and mixing capabilities. This results in poor raw material grinding and fineness, uneven particle size, and insufficient mixing of various raw materials. Consequently, significant differences in local component concentrations are easily observed, severely impacting the quality and performance of the finished composite carbon source. Furthermore, the grinding and stirring structures of existing equipment often operate independently, leading to low equipment integration, large footprint, cumbersome operation procedures, and low production efficiency. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, the present invention provides a composite carbon source manufacturing apparatus and method. By integrating crushing and stirring functions into one unit, the equipment structure is simplified, production efficiency is improved, the uniformity of raw material mixing is enhanced, and the quality of the finished composite carbon source is optimized. Equipped with a hydraulic cylinder, it can drive the overall lifting and lowering of the crushing and stirring components. After crushing, the upper and lower grinding discs can be completely immersed in the liquid, allowing the residual material in the gap between the grinding discs to fully dissolve, preventing material agglomeration, and ensuring the quality of subsequent production, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a composite carbon source manufacturing device, comprising a frame, a mixing tank installed inside the frame, a sealing cover detachably installed on the top of the mixing tank, a circular hole at the center of the top of the sealing cover, a rotating rod passing through the circular hole, a crushing component and a stirring component sleeved on the outer wall of the rotating rod, the crushing component including a connecting frame movably sleeved on the outer wall of the rotating rod, an upper grinding disc fixedly installed at the bottom of the connecting frame, an upper grinding groove opened at the bottom of the upper grinding disc, a lower grinding disc installed inside the upper grinding groove, the lower grinding disc fixedly sleeved on the outer wall of the rotating rod, the rotating rod rotating to drive the lower grinding disc to rotate, the stirring component including two stirring blades, the two stirring blades respectively fixed on both sides of the rotating rod below the lower grinding disc, and a branch plate fixedly installed inside each of the two stirring blades.

[0007] In a preferred embodiment, the top of the connecting frame is fixedly provided with a plurality of limiting rods arranged in a circular array, and the top of the sealing cover is provided with limiting holes of the same number as the limiting rods. The top of the limiting rods passes through the limiting holes and extends to the outside of the sealing cover. By cooperating with the limiting holes, the limiting rods arranged in a circular array can accurately limit the connecting frame and the upper grinding disc, preventing the upper grinding disc from shifting during operation and ensuring the grinding accuracy of the upper and lower grinding discs.

[0008] In a preferred embodiment, a hydraulic cylinder is fixedly inserted through the top center of the frame, and a lifting plate is fixedly provided at the bottom end of the piston rod of the hydraulic cylinder. The side wall of the lifting plate contacts the inner wall of the frame, and a drive mechanism is fixedly provided at the bottom of the lifting plate. The hydraulic cylinder can drive the lifting plate, the bottom drive mechanism, and the rotating rod to lift as a whole, which facilitates equipment maintenance, material feeding, and tank cleaning.

[0009] In a preferred embodiment, the drive mechanism includes a drive frame fixed to the bottom of the lifting plate. A geared motor is fixedly installed inside the drive frame. The bottom end of the output shaft of the geared motor is connected to the top end of the rotating rod to drive the rotating rod to rotate. The geared motor can provide a stable and controllable speed, adapting to different speed requirements of the crushing and mixing processes, and ensuring the smooth operation of the equipment.

[0010] In a preferred embodiment, a feeding pipe is fixedly provided on both the connecting frame and one side of the mixing tank. The top end of the feeding pipe on the connecting frame passes through the sealing cover and extends out of the outer side of the sealing cover. Solid raw materials can be directly fed into the crushing component through the feeding pipe on the connecting frame, so that the raw materials can directly enter between the upper and lower grinding discs for fine grinding, avoiding the problem of incomplete crushing caused by the raw materials falling directly into the mixing tank. Liquid raw materials are then fed into the mixing tank through the feeding pipe on the mixing tank.

[0011] In a preferred embodiment, a control valve is fixedly installed at the bottom center of the mixing tank. The control valve is connected to the inside of the mixing tank. A rubber sealing ring is provided between the control valve and the mixing tank to fill the gap between them. The control valve can accurately control the discharge speed and discharge volume of the finished material, and the rubber sealing ring can effectively seal the connection gap, prevent material leakage, and improve the sealing performance of the equipment.

[0012] In a preferred embodiment, two vertically distributed mounting blocks are fixedly fitted on the outer wall of the mixing tank. Each mounting block has a limiting groove at its bottom. Two vertically distributed limiting blocks are fixedly fitted on the inner walls of both sides of the frame. The limiting blocks are located in the limiting grooves and connected to the mounting blocks. Through the engagement of the mounting blocks and the limiting blocks, the mixing tank can be quickly positioned and installed, limiting the shaking and displacement of the mixing tank during operation and improving the overall stability of the equipment.

[0013] In a preferred embodiment, side supports are fixedly provided on both sides of the frame, and stairs are fixedly provided inside the two side supports. Multiple evenly distributed fixing holes are provided at the bottom of the frame and the side supports. The side supports and stairs work together to facilitate staff to climb up to perform equipment maintenance, material feeding, and observation of equipment operation status, thereby improving the ease of equipment operation. The design of multiple fixing holes can also improve the stability of the entire device.

[0014] The present invention also includes a method for manufacturing the composite carbon source manufacturing apparatus, comprising the following steps: Step 1: The solid and liquid raw materials required for preparing the composite carbon source are fed into the feed pipe on the sealed cover and the feed pipe on the side of the mixing tank, respectively, so that the solid raw materials directly enter the upper grinding groove between the upper and lower grinding discs. Step 2: Start the geared motor to drive the rotating rod to rotate. The rotating rod drives the lower grinding disc to rotate inside the upper grinding groove. The upper grinding groove and the rotating lower grinding disc form a relative grinding structure, which squeezes, shears and grinds the solid raw material in the groove, crushing the raw material into uniform fine particles. The crushed material falls naturally into the mixing tank cavity under the action of gravity. Step 3: When the rotating rod rotates, it drives the stirring blades on both sides of the bottom to rotate synchronously. The stirring blades stir the falling crushed material in all directions. The branch plates inside the stirring blades further disperse the material, breaking up the material layering and clumping, so that raw materials of different types and particle sizes can be fully mixed and achieve the initial homogeneous fusion of raw materials. Step 4: Adjust the speed of the reduction motor according to the raw material ratio to ensure that all raw materials are in full contact, dissolved and reacted in the mixing tank, eliminating the concentration difference of material components and forming a composite carbon source mixture with stable performance and uniform composition. Step 5: After the reaction is complete, open the control valve at the bottom of the mixing tank, adjust the valve opening according to the collection requirements, control the discharge speed of the finished product, and collect the discharged finished product through external collection equipment.

[0015] The technical effects and advantages of this invention are as follows: 1. This invention uses a rotating rod to simultaneously drive the lower grinding disc for grinding and pulverizing and the stirring blades for mixing and stirring, thereby achieving integrated grinding and stirring operations, simplifying the equipment structure, improving production efficiency, and enhancing the uniformity of raw materials. At the same time, the stirring blades and branch plates work together to further improve the uniformity of raw material mixing, allowing various raw materials to be fully integrated and effectively improving the quality of the composite carbon source product. 2. By setting up a hydraulic cylinder lifting structure, the crushing and mixing components can be lifted as a whole. After crushing, the upper and lower grinding discs can be completely submerged in the liquid, so that the residual crushed material between the lower grinding disc and the upper grinding tank can be fully dissolved, avoiding the crushed material from clumping and affecting the subsequent manufacturing quality. The crushing and mixing components can also be lifted out of the mixing tank for easy cleaning and replacement. 3. The mixing tank is positioned and connected to the limit block on the frame through the mounting block and the limit groove, which makes the installation stable and easy to disassemble; the side supports and stairs are set on both sides of the frame, which makes it convenient for operators to feed materials and perform equipment maintenance at high positions, thus improving operational safety.

Detailed Implementation

[0018] 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.

[0019] Refer to the instruction manual appendix Figures 1-8 The present invention provides a composite carbon source manufacturing device, including a frame 1, a mixing tank 2 installed inside the frame 1, a sealing cover 3 detachably installed on the top of the mixing tank 2, a circular hole 4 opened at the center of the top of the sealing cover 3, and a rotating rod 5 passing through the circular hole 4.

[0020] The outer wall of the rotating rod 5 is fitted with a crushing component 6 and a stirring component 7. The crushing component 6 includes a connecting frame 601 that is movably fitted on the outer wall of the rotating rod 5. An upper grinding disc 602 is fixedly provided at the bottom of the connecting frame 601. An upper grinding groove 603 is provided at the bottom of the upper grinding disc 602. A lower grinding disc 604 is provided inside the upper grinding groove 603. The lower grinding disc 604 is fixedly fitted on the outer wall of the rotating rod 5. When the rotating rod 5 rotates, it drives the lower grinding disc 604 to rotate. The lower grinding disc 604 cooperates with the inner wall of the upper grinding groove 603 to squeeze and grind the input raw materials, thereby achieving fine crushing of the raw materials.

[0021] like Figure 3 As shown, the stirring assembly 7 includes two stirring blades 701, which are respectively fixed on both sides of the rotating rod 5 below the lower grinding disc 604. Each of the two stirring blades 701 has a branch plate 702 fixed inside. The branch plate 702 can break up the material vortex, expand the stirring coverage, prevent the material from clumping and separating, and improve the mixing uniformity.

[0022] The top of the connecting frame 601 is fixedly provided with a plurality of limiting rods 8 arranged in a circular array. The top of the sealing cover 3 is provided with the same number of limiting holes 9 as the limiting rods 8. The top of the limiting rods 8 passes through the limiting holes 9 and extends to the outside of the sealing cover 3. Through the sliding cooperation between the limiting rods 8 and the limiting holes 9, the connecting frame 601 and the upper grinding disc 602 are circumferentially limited, ensuring that the upper grinding disc 602 is fixed and only the lower grinding disc 604 rotates to grind, thus ensuring the crushing effect.

[0023] like Figure 1 , Figures 6-8As shown, a hydraulic cylinder 10 is fixedly inserted through the top center of the frame 1. A lifting plate 11 is fixedly provided at the bottom end of the piston rod of the hydraulic cylinder 10. The side wall of the lifting plate 11 is in contact with the inner wall of the frame 1. A drive mechanism 12 is fixedly provided at the bottom of the lifting plate 11. The drive mechanism 12 includes a drive frame 1201 fixed at the bottom of the lifting plate 11. A reduction motor 1202 is fixedly provided inside the drive frame 1201. The bottom end of the output shaft of the reduction motor 1202 is connected to the top end of the rotating rod 5 to drive the rotating rod 5 to rotate. At the same time, the speed can be adjusted according to production needs to adapt to the crushing and mixing needs of different raw materials.

[0024] like Figures 1-5 As shown, a feeding pipe 13 is fixedly provided on both the connecting frame 601 and one side of the mixing tank 2. The top end of the feeding pipe 13 on the connecting frame 601 passes through the sealing cover 3 and extends out of the outer side of the sealing cover 3. Solid raw materials can be directly fed into the grinding area through the feeding pipe 13 to avoid the raw materials falling directly into the mixing tank 2 without being crushed, thus ensuring that the raw materials are thoroughly crushed from the source. Liquid raw materials can enter the mixing tank 2 from the feeding pipe 13 on one side of the mixing tank 2 to achieve solid-liquid separation.

[0025] A control valve 14 is fixedly installed at the bottom center of the mixing tank 2. The control valve 14 is connected to the inside of the mixing tank 2 and is used to control the discharge of finished materials. A rubber sealing ring 15 is provided between the control valve 14 and the mixing tank 2 to fill the gap between them, effectively filling the gap, preventing material leakage, and improving the sealing performance of the equipment.

[0026] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the outer wall of the mixing tank 2 is fixedly fitted with two vertically distributed mounting blocks 16. The bottom of each mounting block 16 is provided with a limiting groove 17. The inner walls on both sides of the frame 1 are fixedly fitted with two vertically distributed limiting blocks 18. The limiting blocks 18 are located in the limiting grooves 17 and connected to the mounting blocks 16, so as to realize the precise positioning and assembly of the mixing tank 2 and the frame 1, limit the shaking and displacement of the mixing tank 2 during operation, and greatly improve the stability of equipment operation.

[0027] like Figure 1 , Figures 6-8 As shown, side supports 19 are fixed on both sides of the frame 1, and stairs 20 are fixed inside the two side supports 19. Multiple evenly distributed fixing holes 21 are opened at the bottom of the frame 1 and the side supports 19, which facilitates the staff to climb up to complete operations such as feeding, equipment inspection, and component debugging, thereby improving the ease of use of the equipment. At the same time, the design of multiple fixing holes 21 can effectively improve the stability of the entire device.

[0028] The present invention also includes a method for manufacturing the composite carbon source manufacturing apparatus, comprising the following steps: Step 1, Raw material feeding: The staff climbs up the stairs 20 of the side support 19 and feeds the solid raw materials required for the preparation of composite carbon source into the upper grinding groove 603 between the upper grinding disc 602 and the lower grinding disc 604 through the feeding pipe 13 on the sealing cover 3. The raw materials are fed directly into the upper grinding groove 603 between the upper grinding disc 602 and the lower grinding disc 604 to complete the fixed-point feeding. The liquid raw materials are fed into the mixing tank 2 from the feeding pipe 13 on one side.

[0029] Step 2, fine grinding of raw materials: Start the geared motor 1202 to drive the rotating rod 5 to rotate. The rotating rod 5 drives the lower grinding disc 604 to rotate inside the upper grinding groove 603. The upper grinding groove 603 and the rotating lower grinding disc 604 form a relative grinding structure, which squeezes, shears and grinds the solid raw materials in the groove, crushing the raw materials into uniform fine particles. The crushed material falls naturally into the cavity of the mixing tank 2 under the action of gravity.

[0030] Step 3: Multi-stage uniform mixing: When the rotating rod 5 rotates, it drives the stirring blades 701 on both sides of the bottom to rotate synchronously. The stirring blades 701 stir the falling crushed material in all directions. The branch plates 702 inside the stirring blades 701 further disperse the material, break the material layering and clumping phenomenon, and make the raw materials of different types and particle sizes fully mixed to achieve the initial homogeneous fusion of the raw materials.

[0031] Step 4: Constant temperature and pressure reaction and fusion: Adjust the speed of the reduction motor 1202 according to the raw material ratio to ensure that all kinds of raw materials are fully contacted, dissolved and reacted in the mixing tank 2, eliminating the concentration difference of material components and forming a composite carbon source mixture with stable performance and uniform composition.

[0032] Step 5: Controllable discharge of finished product: After the reaction is completed, open the control valve 14 at the bottom of the mixing tank 2, adjust the valve opening according to the collection requirements, control the discharge speed of the finished product, and collect the discharged finished product through external collection equipment.

[0033] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
