Description

Technical Field

[0001] This invention relates to the field of waste liquid treatment technology, and in particular to a bamboo strip steam explosion waste liquid treatment equipment and process. Background Technology

[0002] Steam explosion is a promising and innovative pretreatment method. It uses saturated steam to heat bamboo fiber raw materials to a certain pressure. The high-pressure steam penetrates into the fiber and is released from the closed pores in the form of airflow, causing the fiber to undergo mechanical breakage. Then, the pressure is suddenly reduced to atmospheric pressure to pretreat the bamboo fiber.

[0003] Chinese Patent Application No. 202011428231.4 discloses a biomass steam explosion device, comprising a steam explosion device, an internal steam main pipeline, a steam pipeline inside a tank, a pneumatic linkage device, a material turning device, and a connecting ring. The internal steam main pipeline is fixedly installed inside the steam explosion device. The steam pipelines inside the tank are uniformly fixedly installed on the outer surface of the internal steam main pipeline. All the steam pipelines inside the tank are fixedly installed inside the steam explosion device. The pneumatic linkage device is fixedly installed at the top inside the steam explosion device. The material turning device is uniformly fixedly arranged on the inner wall of the steam explosion device. The connecting ring movably passes through the pneumatic linkage device and the material turning device.

[0004] However, this technical solution has the following problems:

[0005] Bamboo fiber produces a large amount of waste liquid after steam explosion. However, the device does not treat the waste liquid. If it is discharged directly, it will cause environmental pollution. Therefore, there is a need for a device to treat the waste liquid generated by the steam explosion of bamboo.

[0006] In addition, Chinese patent application No. 202210013875.X discloses a fermentation device for enhancing electron transfer in anaerobic fermentation, including a fermenter with an insulation jacket on the inner wall of the fermenter. A drive motor is located at the top center of the fermenter, and the drive motor has a rotating shaft connected to the bottom of the fermenter. Multiple electric stirring components are equidistantly arranged on the rotating shaft along its long axis. The patent document describes that during the fermentation process, a weak current can be applied to the anaerobic fermentation system through the electric stirring components to achieve electrochemical catalysis of microorganisms, promote interspecies electron transfer between microorganisms in the fermentation system, and thus improve the biogas production rate.

[0022] Another objective of this invention is to address the shortcomings of existing technologies by providing a bamboo-strip steam explosion wastewater treatment process. This process utilizes a microbial release step combined with a weak discharge step to promote the decomposition of organic matter in the wastewater by microorganisms, thereby converting the wastewater into fertilizer.

[0023] To achieve the above objectives, the present invention provides the following technical solution: a process for treating waste liquid from bamboo chip steam explosion, comprising the following steps:

[0024] Step 1, Feeding Process: Waste liquid enters the reaction tank through the feed pipe;

[0025] Step 2, Microbial Release Process: Drive the toothed ring a to rotate, drive the gear a to rotate, drive the rotating plate to rotate, and drive the microbial enrichment mechanism to be located in the waste liquid. Drive the toothed ring b to rotate, drive the gear b to rotate, drive the rotating shaft to rotate, and then tighten the rope, open the sealing cover, so that the biocarbon ring comes into contact with the waste liquid, which facilitates the microorganisms in the biocarbon ring to seep into the waste liquid, multiply in large quantities, and decompose organic matter.

[0026] Step 3, Weak Discharge Process: By driving the gear ring a to rotate, the gear a rotates, causing the rotating plate to rotate, driving the discharge mechanism downwards. By driving the arc plate to rise, the arc buckle moves to the fixed ring b. At this time, the arc buckle is in the open state. By driving the transmission rod to rotate, the gear c rotates, driving the arc buckle to rotate and pass through the fixed ring b, thus making the arc buckle and the fixed ring b snap together. By driving the arc plate to descend, the flexible conductive sheet is unwound. The arc buckle pulls the flexible conductive sheets on both sides downwards. A weak current can be applied to the fermentation waste liquid through the flexible conductive sheet to achieve electrochemical catalysis of microorganisms, promote interspecies electron transfer between microorganisms in the fermentation system, and promote microbial decomposition.

[0027] Step 4, Microbial disinfection process: Increasing the current passing through the flexible conductive sheet can completely disinfect harmful microorganisms in the waste liquid, which is conducive to the subsequent discharge of waste liquid in compliance with standards.

[0028] The beneficial effects of this invention are as follows:

[0029] (1) After entering the reaction tank through the feed pipe, the microbial enrichment mechanism puts microorganisms into the waste liquid to reproduce and decompose organic matter in the waste liquid. The stirring mechanism stirs the waste liquid in the reaction tank, and the discharge mechanism releases a weak current to promote the decomposition of organic matter in the waste liquid by microorganisms, thus converting the waste liquid into fertilizer.

[0030] (2) In this invention, the arc plate is driven to rise until the arc buckle moves to the fixed ring b. The transmission rod is driven to rotate, which drives the arc buckle to rotate and pass through the fixed ring b, thereby making the arc buckle and the fixed ring b snap together. The arc plate is driven to fall, which realizes the unwinding of the flexible conductive sheet. The arc buckle pulls the flexible conductive sheets on both sides downward. A weak current can be applied to the fermentation waste liquid through the flexible conductive sheet to realize the electrochemical catalysis of microorganisms, promote the interspecies electron transfer between microorganisms in the fermentation system, and promote the decomposition of microorganisms.

[0031] (3) The present invention drives the moving block to move through the linear drive a, drives the two horizontal plates to move through the connecting rod a, drives the flexible conductive sheet to swing along both sides, expands the discharge area of ​​the flexible conductive sheet, and at the same time, when winding, it can also drive the flexible conductive sheet to shake, which makes it easier for the scum to detach from the flexible conductive sheet.

[0032] (4) The present invention drives the toothed ring b to rotate, which in turn drives the gear b to rotate, which in turn drives the rotating shaft to rotate, thereby loosening the rope. The elastic force of the reset spring will drive the closing cover to close and wrap the bio-carbon ring inside, preventing the current passing through the flexible conductive sheet from being conducted to the bio-carbon ring, thus protecting the microorganisms inside the bio-carbon ring and facilitating the operation of the next weak discharge process.

[0033] (5) In this invention, the drive gear f rotates, which drives the gear d to rotate, and then drives the connecting rod b to rotate, so that the two cleaning rollers clamp the flexible conductive sheet. The motor drives the gear h to rotate, which drives the gear g to rotate. The transmission part drives the two cleaning rollers to rotate. A brush is set on the cleaning roller to remove the floating scum on the flexible conductive sheet.

[0034] (6) When the present invention drives the cleaning roller to rotate and drives the threaded block to clean the floating scum on the flexible conductive sheet, the threaded block not only transmits the floating scum downward along the direction of the flexible conductive sheet (i.e., the y direction), but also transmits the floating scum along the x direction, which makes it easier for the floating scum to fall off along both ends of the flexible conductive sheet and enhances the cleaning effect.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0062] Example 1

[0063] like Figure 1 and Figure 2 As shown, this embodiment provides a bamboo chip steam explosion waste liquid treatment device, including: a reaction tank 1; the reaction tank 1 is provided with a feed pipe 11 and a discharge pipe 12; a stirring mechanism 2, which is located inside the reaction tank 1; a microbial enrichment mechanism 3; and a discharge mechanism 4; wherein, the microbial enrichment mechanism 3 is located at one end of the stirring mechanism 2, and the discharge mechanism 4 is located at the other end of the stirring mechanism 2.

[0064] In this embodiment, after the waste liquid enters the reaction tank 1 through the feed pipe 11, the microbial enrichment mechanism 3 puts microorganisms into the waste liquid to reproduce and decompose organic matter in the waste liquid. The stirring mechanism 2 stirs the waste liquid in the reaction tank 1, and the discharge mechanism 4 releases a weak current to promote the decomposition of organic matter by microorganisms.

[0065] Further, such as Figure 3 As shown, the stirring mechanism 2 includes: a lifting block 21; a rotating rod 22, with multiple sets of rotating rods 22 disposed on the lifting block 21; a rotating plate 23, which is mounted on the rotating rod 22; and a driving assembly a24, which is used to drive the rotating plate 23 to rotate. The microbial enrichment mechanism 3 is disposed at one end of the rotating plate 23, and the discharge mechanism 4 is disposed at the other end of the rotating plate 23. The lifting block 21 is preferably driven to rise or fall by a cylinder.

[0066] Further, such as Figure 4The microbial enrichment mechanism 3 includes: a biochar ring 31, with a groove a231 at one end of a rotating plate 23, the biochar ring 31 being installed in the groove a231, and multiple sets of through holes 311 being opened in the biochar ring 31; two sets of fixing rods a32, which are installed in the groove a231; and a sealing cover 33, with two sets of sealing covers 33 symmetrically arranged on the upper and lower ends and rotatably mounted on the fixing rods a32, and sector gears n331 installed on the sealing cover 33, the two sets of sector gears n331 meshing with each other, the sealing cover 33 being made of insulating material, and the biochar ring 31 being sintered under vacuum. During the anaerobic fermentation process, the rich porous structure of biochar can enrich fermenting microorganisms.

[0067] Reset component 34, located at one end of the sealing cover 33, causes the sealing cover 33 to close the biocarbon ring 31; drive component b35, drives the sealing cover 33 to open.

[0068] In this embodiment, Figure 6 This shows the unfolded state. Figure 7 The diagram shows the closed state; preferably, such as Figure 8 and Figure 9 As shown, the reset assembly 34 includes: a reset spring 341, which is sleeved on the outside of the fixed rod a32; and a fixing ring a342, which is installed at both ends of the reset spring 341, one fixing ring a342 being installed with the fixed rod a32 and the other fixing ring a342 being installed with the closing cover 33.

[0069] It should be noted that, without the action of external force, the elastic force of the return spring 341 will drive the closing cover 33 to close and wrap the bio-carbon ring 31 inside, thereby protecting the bio-carbon ring 31.

[0070] Furthermore, the drive assembly b35 includes: a connecting block a351, which is mounted on the closed cover 33; a rotating shaft 352, which is rotatably disposed within the rotating rod 22; and a rope 353, one end of which is connected to the connecting block a351 and the other end of which is connected to the rotating shaft 352. In the original state, under the elastic force of the return spring 341, the closed cover 33 is driven to wrap the bio-carbon ring 31. Rotating the rotating shaft 352 pulls the connecting block a351 through the rope 353, thereby driving the closed cover 33 to open. The closed cover 33 is made of insulating material.

[0071] In this embodiment, the motor drives the gear ring a243 to rotate, which in turn drives the gear a241 to rotate, causing the rotating plate 23 to rotate. This positions the microbial enrichment mechanism 3 within the waste liquid. The motor also drives the gear ring b244 to rotate, which in turn drives the gear b242 to rotate, causing the rotating shaft 352 to rotate. This tightens the rope 353, opening the sealing cover 33, as shown in the following description. Figure 6As shown, the bio-carbon ring 31 is brought into contact with the waste liquid, which facilitates the microorganisms in the bio-carbon ring 31 to infiltrate into the waste liquid, multiply in large quantities, and decompose organic matter.

[0072] Further, such as Figure 11 As shown, the discharge mechanism 4 includes: a protective cover 41, which is installed at the other end of the rotating plate 23, and a receiving groove 411 is provided inside the protective cover 41;

[0073] An unwinding shaft 42 is located inside a protective cover 41; a flexible conductive sheet 43 is wound up inside the unwinding shaft 42; in this embodiment, the flexible conductive sheet 43 has two layers; an auxiliary component 44 drives the unwinding shaft 42 to unwind; a connecting block b45 is installed at one end of the flexible conductive sheet 43 and is located in a receiving groove 411; a reset unit 46 provides power for the unwinding shaft 42 to rewind, preferably driven by a spring-loaded mechanism. Without external force, the reset unit 46 drives the unwinding shaft 42 to rewind the flexible conductive sheet 43, so that the connecting block b45 is located in the receiving groove 411.

[0074] Further, such as Figure 11 As shown, the auxiliary component 44 includes: an arc-shaped plate 441 with a groove b4411 inside; a sliding seat 442 slidably disposed on the arc-shaped plate 441, of which there are two sets; a sliding rod 4421 passing through the groove b4411 is installed at the bottom of the sliding seat 442, and a fixed rod b4422 is installed on the sliding rod 4421; a linear drive a443 installed at the bottom of the arc-shaped plate 441; a moving block 444 installed at the output end of the linear drive a443; a connecting rod a446 disposed between the fixed rod b4422 and the moving block 444; and a locking part 445 for locking the connecting block b45. The linear drive a443 is preferably a cylinder.

[0075] like Figures 12 to 15 As shown, the locking part 445 includes: a fixing ring b4451, multiple sets of fixing rings b4451 are installed on the connecting block b45; a horizontal plate 4453, the horizontal plate 4453 is installed on the sliding seat 442, and multiple sets of arc-shaped grooves 44531 are opened in the horizontal plate 4453; an arc-shaped buckle 4454, the arc-shaped buckle 4454 slidably disposed in the arc-shaped groove 44531 and has teeth 44541 on its outer side; a transmission rod 4455, the transmission rod 4455 is rotatably disposed in the horizontal plate 4453; and a gear c4456, the gear c4456 is installed on the transmission rod 4455 and meshes with the teeth 44541. The transmission rod 4455 is driven to rotate by a motor, which drives the gear c4456 to rotate, thereby driving the arc-shaped buckle 4454 to slide in the arc-shaped groove 44531.

[0076] The drive assembly a24 includes: a gear a241 mounted on the rotating rod 22; a gear b242 mounted on the rotating shaft 352; a gear ring a243 mounted in the lifting block 21 and meshing with the gear a241; and a gear ring b244 mounted in the lifting block 21 and meshing with the gear b242.

[0077] In this embodiment, the motor drives the gear ring a243 to rotate, which in turn drives the gear a241 to rotate, causing the rotating plate 23 to rotate. This causes the discharge mechanism 4 to face downwards, and the cylinder drives the arc plate 441 to rise until the arc-shaped buckle 4454 moves to the fixed ring b4451. At this time, the state of the arc-shaped buckle 4454 is as follows: Figure 14 The open state is shown;

[0078] The motor drives the transmission rod 4455 to rotate, which in turn drives the gear c4456 to rotate, causing the arc-shaped buckle 4454 to rotate and pass through the fixing ring b4451, thus locking the arc-shaped buckle 4454 and the fixing ring b4451 together, as shown in the figure. Figure 11 As shown, by driving the arc-shaped plate 441 to descend, the flexible conductive sheet 43 is unwound, and the arc-shaped buckle 4454 pulls the flexible conductive sheets 43 on both sides downward, as shown in the figure. Figure 17 As shown, a weak current can be applied to the fermentation waste liquid through the flexible conductive sheet 43 to achieve electrochemical catalysis of microorganisms, promote interspecies electron transfer among microorganisms in the fermentation system, and promote microbial decomposition.

[0079] It should be noted that: the linear drive component a443 drives the moving block 444 to move, and through the connecting rod a446 drives the two horizontal plates 4453 to move, which drives the flexible conductive sheet 43 to swing along both sides, thus expanding the discharge area of ​​the flexible conductive sheet 43.

[0080] By increasing the current passing through the flexible conductive sheet 43, harmful microorganisms in the waste liquid can be completely eliminated, which is conducive to the subsequent discharge of waste liquid in compliance with standards. It should be noted that: by driving the toothed ring b244 to rotate by the motor, the gear b242 is driven to rotate, which in turn drives the rotating shaft 352 to rotate, thereby loosening the rope 353. The elastic force of the return spring 341 will drive the closing cover 33 to close, wrapping the bio-carbon ring 31 inside, preventing the current passing through the flexible conductive sheet 43 from being conducted to the bio-carbon ring 31, thus protecting the microorganisms inside the bio-carbon ring 31 and facilitating the operation of the next weak discharge process.

[0081] Example 2

[0082] like Figure 16As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0083] This embodiment also includes a cleaning mechanism 5, which is used to clean the floating scum remaining on the flexible conductive sheet 43. As can be seen from Embodiment 1, when the flexible conductive sheet 43 is wound up, some floating scum from the waste liquid will remain on the flexible conductive sheet 43. The floating scum will enter the receiving groove 411 and jam the flexible conductive sheet 43, thereby affecting the winding of the flexible conductive sheet 43 by the reset unit 46. Therefore, it is necessary to clean the floating scum on the flexible conductive sheet 43.

[0084] Preferred, such as Figure 19 and Figure 21 As shown, the cleaning mechanism 5 includes: a clamping cleaning component 51, with two sets of clamping cleaning components 51 respectively disposed on one side of the connecting block b45; and a driving component c52, which drives the clamping cleaning component 51 to clean the residual scum on the flexible conductive sheet 43.

[0085] Further, such as Figure 20 As shown, the clamping and cleaning assembly 51 includes: cleaning rollers 511, with two sets of cleaning rollers 511 disposed on both sides of the receiving groove 411; connecting rod b512, which is mounted on both sides of the cleaning rollers 511; sector gear k513, which is mounted on one end of the connecting rod b512; gear d514, which is rotatably mounted on the protective cover 41 and meshes with the sector gear k513; and gear e515, which is mounted on the other end of the connecting rod b512.

[0086] The drive assembly c52 includes: a gear f521, which is rotatably mounted on the protective cover 41; a gear g522, which is mounted on one end of the connecting rod b512; a gear h523, which is rotatably mounted on the gear f521; and a transmission part 524, which connects the gear g522 and the gear e515. The transmission part 524 is preferably belt driven.

[0087] In this embodiment, the motor drives gear f521 to rotate, which in turn drives gear d514 to rotate, thereby driving connecting rod b512 to rotate. This allows the two cleaning rollers 511 to clamp the flexible conductive sheet 43, as shown in the following state. Figure 22 As shown, at this time, the two gears e515 are in a meshing state, and gear f521 is locked and stationary. The motor drives gear h523 to rotate, which in turn drives gear g522 to rotate. The transmission part 524 drives the two cleaning rollers 511 to rotate. Brushes can be set on the cleaning rollers 511. When the flexible conductive sheet 43 is wound up, the floating scum on the flexible conductive sheet 43 is removed.

[0088] To further improve the cleaning effect, the cleaning roller 511 is equipped with a threaded block 5111, the threads on both sides of the threaded block 5111 are arranged in opposite directions, and the threaded block 5111 is equipped with a brush, such as... Figure 23 As shown, when the cleaning roller 511 rotates and drives the threaded block 5111 to clean the floating scum on the flexible conductive sheet 43, the threaded block 5111 not only transports the floating scum downward along the direction of the flexible conductive sheet 43 (i.e., the y direction), but also transports the floating scum along the x direction, which makes it easier for the floating scum to fall off along the direction of the flexible conductive sheet 43 and enhances the cleaning effect.

[0089] Example 3

[0090] like Figures 1 to 23 As shown, this embodiment provides a process for treating waste liquid from bamboo chip steam explosions, including the following steps:

[0091] Step 1, Feeding process: Waste liquid enters reaction tank 1 through feed pipe 11;

[0092] Step 2, Microbial Release Process: The motor drives the gear ring a243 to rotate, which in turn drives the gear a241 to rotate, causing the rotating plate 23 to rotate. This positions the microbial enrichment mechanism 3 within the waste liquid. The motor then drives the gear ring b244 to rotate, which in turn drives the gear b242 to rotate, causing the rotating shaft 352 to rotate. This tightens the rope 353, opening the sealing cover 33, as shown in the image. Figure 6 As shown, the bio-carbon ring 31 is brought into contact with the waste liquid, which facilitates the microorganisms in the bio-carbon ring 31 to infiltrate into the waste liquid, multiply in large quantities, and decompose organic matter.

[0093] Step 3, Weak Discharge Process: The motor drives the gear ring a243 to rotate, which in turn drives the gear a241 to rotate, causing the rotating plate 23 to rotate. This causes the discharge mechanism 4 to face downwards, and the cylinder drives the arc plate 441 to rise until the arc-shaped buckle 4454 moves to the fixed ring b4451. At this time, the arc-shaped buckle 4454 is in the following state: Figure 14 In the open state shown, the motor drives the transmission rod 4455 to rotate, which in turn drives the gear c4456 to rotate, causing the arc-shaped buckle 4454 to rotate and pass through the fixing ring b4451. This causes the arc-shaped buckle 4454 and the fixing ring b4451 to engage together, as shown in the diagram. Figure 11 As shown, by driving the arc-shaped plate 441 to descend, the flexible conductive sheet 43 is unwound, and the arc-shaped buckle 4454 pulls the flexible conductive sheets 43 on both sides downward, as shown in the figure. Figure 17 As shown, a weak current can be applied to the fermentation waste liquid through the flexible conductive sheet 43 to achieve electrochemical catalysis of microorganisms, promote interspecies electron transfer among microorganisms in the fermentation system, and promote microbial decomposition.

[0094] Step 4, Microbial disinfection process: Increasing the current passing through the flexible conductive sheet 43 can completely disinfect harmful microorganisms in the waste liquid, which is conducive to the subsequent discharge of waste liquid in compliance with standards.

[0095] 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, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
