Description

A carbon source preparation device with concentration detection function Technical Field

[0001] The present invention relates to the technical field of carbon source preparation, in particular to a carbon source preparation device with a concentration detection function. Background Art

[0002] With the improvement of people's living standards, the output of food waste is also increasing day by day. Food waste is often treated by sanitary landfill. However, food waste has a high water content and a large amount of organic matter, and is very easy to rot. Landfill-treated food waste will produce a large amount of leachate, which will further pollute the environment and is not conducive to environmental protection. Therefore, food waste needs to be harmlessly treated.

[0003] On the other hand, the denitrification and phosphorus removal processes in the sewage treatment process require the consumption of a large amount of organic carbon sources. The carbon sources are generally organic substances such as methanol, sodium acetate, and glucose. These organic substances have been widely used in the field of sewage treatment, but the cost is too high. Therefore, more effective and low-cost organic carbon sources are needed to meet the needs. The organic matter content in food waste is high. By treating food waste through degradation and chain breaking processes, the particulate organic matter can be converted into dissolved organic matter, and the large molecular substances can be converted into small molecular substances, and high-quality carbon sources can be produced at a lower cost. In this way, high-quality carbon sources can be obtained while treating food waste, and the harmless and resource-based treatment of food waste can be achieved.

[0004] However, the existing reaction equipment for preparing carbon sources from food waste mainly uses uniform and simple hydrolysis and acidification or filtration, without a complete degradation and chain breaking system. It is also impossible to detect the carbon source concentration (expressed as chemical oxygen demand COD) in real time during the reaction process, and the production quality cannot be guaranteed.

[0005] Summary of the Invention

[0006] The object of the present invention is to provide a carbon source preparation device with a concentration detection function to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: the carbon source preparation equipment includes a frame, a tank body, a stirring system, and a detection system. The tank body is tightly connected to the frame, the tank body is used to hydrolyze and acidify the kitchen waste slurry, the stirring system is tightly connected to the tank body, the detection system is tightly connected to the stirring system, the detection system has a built-in sensor for detecting the concentration of the carbon source, a heating pipe is provided on the outside of the tank body, and the heating pipe is connected to an external heat source.

[0008] The frame provides stable support for the tank body, and the tank body is used to provide a stable environment for the hydrolysis and acidification of kitchen waste slurry. The stirring system works to stir the kitchen waste slurry in the tank body to accelerate the hydrolysis and acidification reaction process and improve the production efficiency of the carbon source. The carbon source concentration in the reaction process is monitored in real time by an external detection system on the tank body. After the COD concentration of the carbon source reaches a certain value, the reaction is terminated in time to prevent overreaction. A heating pipe is set on the outside of the tank body to keep the temperature in the tank body in a suitable range to ensure the smooth progress of the reaction process. The heating pipe can evaporate and concentrate the liquid after the reaction is completed. The detection system can monitor the concentration of the carbon source online in real time, so that when the carbon source is concentrated, it can be judged that the concentrated evaporation time reaches the required concentration and stops in time to reduce energy consumption.

[0009] Furthermore, the stirring system includes a driving motor, a support frame, and a transmission shaft. The support frame is tightly connected to the tank body, the driving motor is tightly connected to the support frame, the output shaft of the driving motor is transmission-connected to the transmission shaft, and a plurality of stirring blades are provided on the transmission shaft.

[0010] The drive motor is the main power source of the stirring system. The support frame is fixed on the tank body to provide an installation base for the drive motor. When the drive motor starts, it transmits the torque to the drive shaft, thereby driving several stirring blades fixed on the drive shaft to rotate, thereby stirring the kitchen waste slurry in the tank body and promoting the hydrolysis and acidification reaction.

[0011] Furthermore, a circulation mechanism is provided in the tank body, which is connected to the detection system and is used to transport the liquid in the tank body to the detection system.

[0012] A large amount of sludge will be produced during the hydrolysis and acidification process of kitchen waste slurry. The sludge has a high density and will gradually settle to the bottom of the tank. It is difficult to mix the slurry evenly by relying solely on the stirring system, resulting in uneven distribution of the slurry in the tank, affecting the production efficiency of the carbon source. The slurry at the bottom of the tank is continuously transported to the detection system for detection through the circulation mechanism. After the detection is completed, it is re-transported to the tank to continue the reaction, forming an external circulation of the slurry, which not only improves the uniformity of the slurry in the tank, but also improves the accuracy of carbon source concentration detection.

[0013] Furthermore, the circulation mechanism includes a connecting seat, a rotor, and blades. The connecting seat is tightly connected to the tank body, the rotor is rotatably connected to the connecting seat, the transmission shaft is rotatably connected to the connecting seat, the transmission shaft is transmission-connected to the rotor, the blades are slidingly connected to the rotor, and a transmission chamber is provided on the connecting seat. The transmission chamber is a cylindrical chamber, the rotor is eccentrically arranged in the transmission chamber, a movable groove is provided on the rotor, the blades are slidingly connected to the movable groove, and water inlet pipes and water outlet pipes are symmetrically provided at both ends of the connecting seat. The water inlet pipe and the water outlet pipe are connected to the transmission chamber, and the water outlet pipe is connected to the detection system.

[0014] The connecting seat is fixed at the bottom of the tank to provide stable support for the rotor. There is eccentricity between the rotor and the transmission chamber. The blades can slide flexibly in the movable groove of the rotor. The transmission shaft is inserted into the transmission chamber to transmit the torque to the rotor. A sealing ring is provided at the connection between the transmission shaft and the connecting seat to ensure the airtightness of the transmission chamber. When the rotor rotates driven by the transmission shaft, the top of the blade is pressed against the inner wall of the transmission chamber under the action of centrifugal force, so that a sealed working chamber is formed between the two adjacent blades, the rotor and the transmission chamber. Because the rotor is eccentric, when the rotor rotates, the blades on the water inlet pipe side extend outward, and the volume of the sealed working chamber gradually increases, generating a vacuum, sucking the slurry from the water inlet pipe, and the blades on the outlet pipe side retract inward, and the volume of the sealed working chamber gradually decreases, thereby discharging the slurry from the outlet pipe into the detection system, realizing the external circulation of the kitchen waste slurry, avoiding the deposition of sludge, and promoting the reaction.

[0015] Furthermore, a grinding mechanism is provided on the inner wall of the tank body, the grinding mechanism is connected to the water outlet of the detection system, and the grinding mechanism is transmission-connected to the stirring system. The grinding mechanism is used to grind large particles in the kitchen waste slurry.

[0016] Kitchen waste slurry is a slurry formed by crushing and squeezing kitchen waste. Incomplete crushing may occur, resulting in some large particles mixed in the slurry, and large particles will precipitate during hydrolysis and acidification. Large particles are difficult to hydrolyze and have low utilization rates. Therefore, during hydrolysis and acidification, large particles are crushed by a grinding mechanism to improve the conversion efficiency of the carbon source. The slurry that has passed the inspection of the detection system is transported to the grinding mechanism through a pipeline for crushing, and the stirring system provides power for the grinding mechanism.

[0017] Furthermore, the grinding mechanism includes a reflux ring and a movable component. The reflux ring is firmly connected to the tank body, the movable component is slidingly connected to the reflux ring, and the movable component is firmly connected to the stirring blade. The movable component is used to grind large particles in the kitchen waste slurry. An annular flow channel is provided in the reflux ring, and the annular flow channel is connected to the water outlet end of the detection system through a pipe. The water outlet of the annular flow channel faces into the tank body.

[0018] The reflux ring is fixed in the tank body to provide support for the movable component. The slurry detected by the detection system is transported to the annular flow channel through the pipeline, and then returns to the tank body through the water outlet for reaction, realizing the external circulation of the slurry. It works together with the stirring blade to promote the flow of slurry in the tank body and improve the reaction efficiency. The reflux ring and the stirring blade are set at the same height, and the movable component is connected to the stirring blade by bolts. In this way, the rotation of the stirring blade can drive the movable component to slide along the circumference of the reflux ring, thereby breaking up large particles in the slurry flowing out of the water outlet.

[0019] Furthermore, there are several water outlets arranged obliquely along the circumference of the annular flow channel, and the inclination direction of several water outlets is opposite to the rotation direction of the stirring blade. The movable component includes a fixed frame, a movable block, a clamping spring, and a grinding roller. The fixed frame is slidably connected to the reflux ring, and the end of the fixed frame away from the reflux ring is tightly connected to the stirring blade. A sliding groove is provided on the fixed frame, and the movable block is slidably connected to the sliding groove. One end of the clamping spring is tightly connected to the inner wall of the sliding groove, and the other end of the clamping spring is tightly connected to the movable block. The rotating shaft of the grinding roller is rotatably connected to the movable block, and a protrusion is provided on the surface of the grinding roller.

[0020] By arranging the water outlet in an inclined direction opposite to the rotation direction of the stirring blade, the flow direction of the slurry guided through the water outlet will be opposite to the flow direction of the slurry affected by the stirring blade in the tank body. The collision between the two can promote the mixing of the slurry, improve uniformity, and improve the reaction efficiency. Driven by the stirring blade, the fixed frame can move along the circumference of the reflux ring, and a sliding groove is provided on the fixed frame to provide installation space for the movable block and the clamping spring. The clamping spring provides elastic force to push the movable block to slide on the sliding groove, thereby pressing the grinding roller to the surface of the annular flow channel. Driven by the stirring blade, the grinding roller will rotate along the movable block under the action of friction, thereby rolling on the surface of the annular flow channel, and under the action of the protrusion, gradually grind and crush large particles in the slurry flowing out of the water outlet, thereby promoting the reaction.

[0021] Furthermore, the side of the reflux ring close to the stirring blade is arc-shaped.

[0022] By setting the surface of the reflow ring to a wavy arc, the grinding roller makes a continuous undulating motion on the surface of the reflow ring, thereby compressing the compression spring, which can increase the pressing force of the grinding roller on the reflow ring surface and improve the grinding effect.

[0023] Furthermore, the tank body is provided with a feeding port and a discharging port.

[0024] The kitchen waste slurry is added into the tank from the feeding port for reaction, and is discharged through the discharging port after the reaction is completed.

[0025] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: by arranging a heating pipe on the outside of the tank body, the temperature inside the tank body is kept in a suitable range, thereby ensuring that the reaction process proceeds smoothly, and the heating pipe can evaporate and concentrate the liquid after the reaction is completed, and the detection system can monitor the concentration of the carbon source online in real time, so that when the carbon source is concentrated, it can be judged that the concentration evaporation time reaches the required concentration and stops in time, thereby reducing energy consumption; the slurry at the bottom of the tank body is continuously transported to the detection system for detection through the circulation mechanism, and after the detection is completed, it is re-transported into the tank body to continue the reaction, forming an external circulation of the slurry The ring not only improves the uniformity of the slurry in the tank body, but also improves the accuracy of carbon source concentration detection; by arranging the water outlet in an inclined direction opposite to the rotation direction of the stirring blade, the flow direction of the slurry guided through the water outlet will be opposite to the flow direction of the slurry affected by the stirring blade in the tank body, and the collision between the two can promote the mixing of the slurry, improve the uniformity, and improve the reaction efficiency; by setting the surface of the reflux ring to a wavy arc, the grinding roller makes a continuous undulating movement on the surface of the reflux ring, thereby compressing the clamping spring, which can increase the pressing force of the grinding roller on the surface of the reflux ring and improve the grinding effect.

DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] The present invention provides a technical solution:

[0038] As shown in Figure 1, the carbon source preparation equipment includes a frame 1, a tank body 2, a stirring system 3, and a detection system 4. The tank body 2 is tightly connected to the frame 1. The tank body 2 is used to hydrolyze and acidify the kitchen waste slurry. The stirring system 3 is tightly connected to the tank body 2. The detection system 4 is tightly connected to the stirring system 3. The detection system 4 has a built-in sensor for detecting the concentration of the carbon source. A heating pipe 5 is provided on the outside of the tank body 2, and the heating pipe 5 is connected to an external heat source.

[0039] The frame 1 provides stable support for the tank body 2, and the tank body 2 is used to provide a stable environment for the hydrolysis and acidification of the kitchen waste slurry. The stirring system 3 works to stir the kitchen waste slurry in the tank body 2 to accelerate the hydrolysis and acidification reaction process and improve the production efficiency of the carbon source. The carbon source concentration in the reaction process is monitored in real time by an external detection system 4 on the tank body 2. After the COD concentration of the carbon source reaches a certain value, the reaction is terminated in time to prevent excessive reaction. By arranging a heating pipe 5 on the outside of the tank body 2, the temperature in the tank body 2 is maintained in a suitable range to ensure that the reaction process proceeds smoothly. The heating pipe 5 can evaporate and concentrate the liquid after the reaction is completed. The detection system 4 can monitor the concentration of the carbon source online in real time, so that when the carbon source is concentrated, it can be judged that the concentrated evaporation time reaches the required concentration and stops in time to reduce energy consumption.

[0040] As shown in Figures 1 and 5, the stirring system 3 includes a driving motor 31, a support frame 32, and a transmission shaft 33. The support frame 32 is tightly connected to the tank body 2, the driving motor 31 is tightly connected to the support frame 32, the output shaft of the driving motor 31 is transmission-connected to the transmission shaft 33, and a number of stirring blades 34 are provided on the transmission shaft 33.

[0041] The drive motor 31 is the main power source of the stirring system 3. The support frame 32 is fixed on the tank body 2 to provide an installation base for the drive motor 31. When the drive motor 31 is started, the torque is transmitted to the transmission shaft 33, thereby driving the several stirring blades 34 fixed on the transmission shaft 33 to rotate, thereby stirring the kitchen waste slurry in the tank body 2 and promoting the hydrolysis and acidification reaction.

[0042] As shown in FIG1 , FIG2 , FIG3 and FIG4 , a circulation mechanism 6 is provided in the tank body 2 , and the circulation mechanism 6 is connected to the detection system 4 . The circulation mechanism 6 is used to transport the liquid in the tank body 2 to the detection system 4 .

[0043] During the hydrolysis and acidification process of the kitchen waste slurry, a large amount of sludge will be produced. The sludge has a high density and will gradually settle to the bottom of the tank body 2. It is difficult to mix the slurry evenly by relying solely on the stirring system 3, resulting in uneven distribution of the slurry in the tank body 2, affecting the production efficiency of the carbon source. The slurry at the bottom of the tank body 2 is continuously transported to the detection system 4 for detection through the circulation mechanism 6. After the detection is completed, it is re-transported to the tank body 2 to continue the reaction, forming an external circulation of the slurry, which not only improves the uniformity of the slurry in the tank body 2, but also improves the accuracy of the carbon source concentration detection.

[0044] As shown in Figures 3 and 4, the circulation mechanism 6 includes a connecting seat 61, a rotor 62, and blades 63. The connecting seat 61 is tightly connected to the tank body 2, the rotor 62 is rotatably connected to the connecting seat 61, the transmission shaft 33 is rotatably connected to the connecting seat 61, the transmission shaft 33 is transmission-connected to the rotor 62, the blades 63 are slidingly connected to the rotor 62, and a transmission chamber 611 is provided on the connecting seat 61. The transmission chamber 611 is a cylindrical chamber. The rotor 62 is eccentrically arranged in the transmission chamber 611. A movable groove 621 is provided on the rotor 62. The blades 63 are slidingly connected to the movable groove 621. An inlet pipe 64 and an outlet pipe 65 are symmetrically provided at both ends of the connecting seat 61. The inlet pipe 64 and the outlet pipe 65 are connected to the transmission chamber 611, and the outlet pipe 65 is connected to the detection system 4.

[0045] The connecting seat 61 is fixed to the bottom of the tank body 2 to provide stable support for the rotor 62. There is an eccentricity between the rotor 62 and the transmission chamber 611. The blades 63 can slide flexibly in the movable groove 621 of the rotor 62. The transmission shaft 33 is inserted into the transmission chamber 611 to transmit the torque to the rotor 62. A sealing ring is provided at the connection between the transmission shaft 33 and the connecting seat 61 to ensure the airtightness of the transmission chamber 611. When the rotor 62 rotates driven by the transmission shaft 33, the top of the blade 63 is pressed against the inner wall of the transmission chamber 611 under the action of the centrifugal force. Thus, the two adjacent blades 63. A sealed working chamber is formed between the rotor 62 and the transmission chamber 611. Because the rotor 62 is eccentrically arranged, when the rotor 62 rotates, the blades 63 on the side of the water inlet pipe 64 extend outward, and the volume of the sealed working chamber gradually increases, generating a vacuum, sucking the slurry from the water inlet pipe 64, while the blades 63 on the side of the water outlet pipe 65 retract inward, and the volume of the sealed working chamber gradually decreases, thereby discharging the slurry from the water outlet pipe 65 into the detection system 4, realizing the external circulation of the kitchen waste slurry, avoiding the deposition of sludge, and promoting the reaction.

[0046] As shown in FIG5 , a grinding mechanism 7 is provided on the inner wall of the tank body 2 , the grinding mechanism 7 is connected to the water outlet of the detection system 4 , and the grinding mechanism 7 is transmission-connected to the stirring system 3 , and the grinding mechanism 7 is used to grind large particles in the kitchen waste slurry.

[0047] The kitchen waste slurry is a slurry formed by crushing and squeezing the kitchen waste. Incomplete crushing may occur, resulting in some large particles mixed in the slurry, and large particles will be precipitated during hydrolysis and acidification. Large particles are difficult to hydrolyze and have low utilization rates. Therefore, the large particles are crushed by the grinding mechanism 7 during hydrolysis and acidification, which can improve the conversion efficiency of the carbon source. The slurry after inspection by the detection system 4 is transported to the grinding mechanism 7 through a pipeline for crushing, and the stirring system 3 provides power for the grinding mechanism 7.

[0048] As shown in Figures 5 and 6, the grinding mechanism 7 includes a reflux ring 71 and a movable component 72. The reflux ring 71 is firmly connected to the tank body 2, the movable component 72 is slidingly connected to the reflux ring 71, and the movable component 72 is firmly connected to the stirring blade 34. The movable component 72 is used to grind large particles in the kitchen waste slurry. An annular flow channel 711 is provided in the reflux ring 71. The annular flow channel 711 is connected to the water outlet end of the detection system 4 through a pipe, and the water outlet 7111 of the annular flow channel 711 faces into the tank body 2.

[0049] The reflux ring 71 is fixed in the tank body 2 to provide support for the movable component 72. The slurry detected by the detection system 4 is transported to the annular flow channel 711 through the pipeline, and then returns to the tank body 2 through the water outlet 7111 for reaction, realizing the external circulation of the slurry. It works together with the stirring blade 34 to promote the flow of slurry in the tank body 2 and improve the reaction efficiency. The reflux ring 71 and the stirring blade 34 are set at the same height, and the movable component 72 and the stirring blade 34 are connected together by bolts. In this way, the rotation of the stirring blade 34 can drive the movable component 72 to slide along the circumference of the reflux ring 71, thereby breaking large particles in the slurry flowing out of the water outlet 7111.

[0050] As shown in Figures 7 and 8, there are several water outlets 7111 arranged obliquely along the circumference of the annular flow channel 711. The inclination direction of the water outlets 7111 is opposite to the rotation direction of the stirring blade 34. The movable component 72 includes a fixed frame 721, a movable block 722, a compression spring 723, and a grinding roller 724. The fixed frame 721 is slidably connected to the reflux ring 71, and the end of the fixed frame 721 away from the reflux ring 71 is fastened to the stirring blade 34. A sliding groove 7211 is provided on the fixed frame 721, and the movable block 722 is slidably connected to the sliding groove 7211. One end 723 of the compression spring is fastened to the inner wall of the sliding groove 7211, and the other end of the compression spring 723 is fastened to the movable block 722. The rotating shaft of the grinding roller 724 is rotatably connected to the movable block 722, and the surface of the grinding roller 724 is provided with a protrusion 7241.

[0051] By arranging the water outlet 7111 in an oblique direction opposite to the rotation direction of the stirring blade 34, the flow direction of the slurry guided through the water outlet 7111 will be opposite to the flow direction of the slurry in the tank body 2 under the action of the stirring blade 34. The collision between the two can promote the mixing of the slurry, improve the uniformity, and improve the reaction efficiency. The fixed frame 721 can move along the circumference of the reflux ring 71 under the drive of the stirring blade 34, and a sliding groove 7211 is provided on the fixed frame 721 to provide a space for the movable block 722 and The compression spring 723 provides installation space, and the compression spring 723 provides elastic force to push the movable block 722 to slide on the sliding groove 7211, thereby pressing the grinding roller 724 to the surface of the annular flow channel 711. Driven by the stirring blade 34, the grinding roller 724 will rotate along the movable block 722 under the action of friction, thereby rolling on the surface of the annular flow channel 711, and under the action of the protrusion 7241, gradually grind and crush large particles in the slurry flowing out of the water outlet 7111, thereby promoting the reaction.

[0052] As shown in FIG7 and FIG8 , the side of the reflux ring 71 close to the stirring blade 34 is arc-shaped.

[0053] By setting the surface of the reflow ring 71 to a wavy arc, the grinding roller 724 makes a continuous undulating motion on the surface of the reflow ring 71, thereby compressing the clamping spring 723, which can increase the pressing force of the grinding roller 724 on the surface of the reflow ring 71 and improve the grinding effect.

[0054] As shown in FIG1 , the tank body 2 is provided with a feeding port 21 and a discharging port 22 .

[0055] The kitchen waste slurry is added into the tank body 2 from the feeding port 21 for reaction, and is discharged through the discharging port 22 after the reaction is completed.

[0056] The working principle of the present invention is as follows: first, the kitchen waste slurry raw material is added into the tank body 2 from the feeding port 21, and then the driving motor 31 is started to transmit the torque to the transmission shaft 33, thereby driving the several stirring blades 34 fixed on the transmission shaft 33 to rotate, thereby stirring the kitchen waste slurry in the tank body 2, and the slurry at the bottom of the tank body 2 is continuously transported to the detection system 4 for detection through the circulation mechanism 6. The slurry detected by the detection system 4 is transported to the annular flow channel 711 through the pipeline, and then returns to the tank body 2 through the water outlet 7111 for reaction, realizing the external circulation of the slurry, and working together with the stirring blades 34 to promote the flow of the slurry in the tank body 2 and improve the reaction efficiency. The movable component 72 is connected to the stirring blade 34 by bolts, so that the rotation of the stirring blade 34 can drive the movable component 72 to slide along the circumference of the reflux ring 71, thereby breaking the large particles in the slurry flowing out of the water outlet 7111, and by aligning the direction of the inclined arrangement of the water outlet 7111 with the rotation of the stirring blade 34 The direction is opposite, so that the flow direction of the slurry guided by the water outlet 7111 will be opposite to the flow direction of the slurry in the tank body 2 under the action of the stirring blade 34. The collision between the two can promote the mixing of the slurry, improve the uniformity, and improve the reaction efficiency. The fixed frame 721 can move along the circumference of the reflux ring 71 under the drive of the stirring blade 34, and a sliding groove 7211 is provided on the fixed frame 721 to provide an installation space for the movable block 722 and the compression spring 723. The compression spring 723 provides elastic force to push the movable block 722 and the compression spring 723 to provide an installation space for the movable block 722 and the compression spring 723 to provide elastic force to push the movable block 722 and the compression spring 723 to provide an installation space for the movable block 722 and the compression spring 723 to provide elastic force to push the movable block 722 and the compression spring 723 to provide an installation space for the movable block 722 and the compression spring 723 to provide an installation space for the movable block 722 and the compression spring 723 to provide an elastic force to push ... The movable block 722 slides on the sliding groove 7211, thereby pressing the grinding roller 724 against the surface of the annular flow channel 711. Driven by the stirring blade 34, the grinding roller 724 rotates along the movable block 722 under the action of friction, thereby rolling on the surface of the annular flow channel 711, and under the action of the protrusion 7241, gradually grinding and crushing large particles in the slurry flowing out of the water outlet 7111 to promote the reaction.
