Description

Technical Field

[0001] The invention relates to the technical field of water pollution control and treatment, in particular to a methyl lactate production wastewater treatment device. Background Art

[0002] Methyl lactate is an important green solvent and chemical intermediate, widely used in pesticide, pharmaceutical, coating and plastic industries. However, during its production process, a large amount of high-concentration organic wastewater is generated. This type of wastewater usually contains high chemical oxygen demand (COD), biodegradable substances and fine suspended particles, which is difficult and costly to treat. If not properly treated, it is very easy to cause serious pollution to the water environment.

[0003] Traditional wastewater treatment methods require coagulation and sedimentation to remove a large amount of suspended solids and some organic matter in the primary treatment stage. In order to improve the flocculation efficiency, chemical flocculants are often added to the wastewater.

[0004] However, most existing wastewater treatment devices adopt a single stirring and dosing mode. This method has some problems. For example, the flocculant is added at one time, which can easily lead to premature formation of flocs or "destabilization". In the absence of dynamic disturbance, it is difficult for tiny particles to fully collide and aggregate, resulting in slow floc formation and poor density, and the subsequent sedimentation efficiency will also be affected. Summary of the invention

[0025] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the following will provide a detailed description of the specific embodiments of the present invention in conjunction with the drawings in the specification.

[0026] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures, or characteristics that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments. Embodiment

[0028] Referring to Figures 1 to 5 , which is the first embodiment of the present invention. This embodiment provides a device for treating wastewater from methyl lactate production. First, the wastewater component 1 allows the wastewater to stand and settle to separate larger particulate impurities. Then, the flocculant is added in batches through the feeding component 2, and the vibration of the flocculation component 3 is enhanced to quickly aggregate fine suspended solids into flocs, so as to achieve efficient sedimentation and interception.

[0029] Specifically, the wastewater component 1 includes a wastewater tank 11 and a stirring shaft 12 disposed inside the wastewater tank 11. The wastewater from methyl lactate production is sent to the wastewater tank 11 through a grid filter. The wastewater stands and precipitates in the wastewater tank 11, and the stirring shaft 12 mixes the wastewater and the flocculant to accelerate the precipitation of impurities.

[0030] Furthermore, the feeding component 2 includes a ratchet disk 21 rotatably disposed inside the wastewater tank 11 and a storage cylinder 22 disposed at the bottom of the ratchet disk 21. The storage cylinder 22 contains a chemical agent for flocculating and precipitating impurities in the wastewater. The ratchet disk 21 drives the storage cylinder 22 to rotate, thereby sprinkling the flocculant.

[0031] The flocculation component 3 includes vibration rods 31 arranged in a circular array outside the stirring shaft 12. The lower ends of the vibration rods 31 extend into the upper layer of the wastewater, and the vibration rods 31 vibrate to accelerate the flocculation rate of the upper-layer wastewater.

[0032] The transmission component 4 includes a ratchet member 41 disposed on the outer wall of the stirring shaft 12. The ratchet member 41 meshes with the ratchet disk 21. During the working rotation of the stirring shaft 12, the ratchet member 41 is driven to move synchronously. The ratchet member 41 meshes and drives the ratchet disk 21 to rotate, thereby sprinkling the flocculant in the storage cylinder 22.

[0033] It should be noted that when the pawl member 41 rotates with the stirring shaft 12, it strikes the vibrating rod 31. When the pawl member 41 contacts the vibrating rod 31, it disengages from the ratchet disc 21. The tail end of the pawl member 41 strikes the vibrating rod 31 during movement. The vibrating rod 31 vibrates upon being struck and transmits the vibration force to the upper-layer wastewater. The vibration accelerates the diffusion of the flocculant in the wastewater, enabling it to contact the suspended particles more evenly, reducing the problem of excessive or too low local concentration of the chemical agent, shortening the mixing time of the flocculant and the particles, improving the reaction efficiency, reducing the dosage of the chemical agent, saving costs, increasing the probability of collision between suspended particles due to the kinetic energy generated by the vibration, promoting the aggregation of fine particles into larger flocs through electro-neutralization or adsorption bridging, accelerating the floc formation speed, shortening the flocculation stage time, generating denser flocs with better sedimentation performance, and the vibration can break the double electric layer or oil film on the particle surface, enhancing the effect of the flocculant and significantly improving the deflocculation effect of colloidal particles.

[0034] Preferably, the wastewater assembly 1 further includes a motor 13 installed at the top of the wastewater tank 11. There is a transmission connection between the output shaft of the motor 13 and the stirring shaft 12. The outer wall of the stirring shaft 12 is provided with stirring blades 14. When the motor 13 is started, it drives the stirring shaft 12 to rotate, thereby driving the stirring blades 14 to rotate and accelerating the flocculation of the wastewater.

[0035] During use, when the pawl member 41 strikes the vibrating rod 31, it rotates itself, causing the tail end of the pawl member 41 to pass through the vibrating rod 31 without affecting the normal rotation of the stirring shaft 12. At this time, the pawl member 41 disengages from the ratchet disc 21, and the ratchet disc 21 loses the external driving force and stops rotating. The chemical agent inside the storage cylinder 22 no longer spills out due to the loss of centrifugal force. After passing through the vibrating rod 31, the pawl member 41 automatically resets and engages with the ratchet disc 21 again, spilling the chemical agent in the storage cylinder 22, thereby realizing the batch addition of the flocculant, avoiding excessive local concentration caused by one-time addition, reducing the residue of the flocculant that is not effectively utilized, and the batch addition can maintain the effective concentration gradient of the flocculant in the reaction system, continuously driving particle collision and aggregation, and avoiding the attenuation of the reaction driving force after one-time addition.

[0036] In summary, in this embodiment, through the static precipitation and mechanical stirring of the wastewater component 1, the intermittent batch feeding of the feeding component 2, the vibration assistance of the flocculation component 3, and the coordinated cooperation of the transmission component 4, an efficient and energy-saving treatment process for methyl lactate production wastewater is achieved. The wastewater component 1 combines static precipitation and stirring, combines the sedimentation of large particles with the mixing reaction of fine suspended particles, and improves the precipitation efficiency of methyl lactate production wastewater; the batch feeding of the feeding component 2 ensures that the concentration of the flocculant can be maintained within the optimal range throughout the reaction process, avoiding the waste of chemicals and low efficiency caused by traditional single-time feeding. The vibration assistance of the flocculation component 3 further accelerates the flocculation reaction rate and improves the floc structure, enhancing the sedimentation performance. The transmission component 4 realizes the coordinated operation of the feeding component 2 and the flocculation component 3, improving the precipitation efficiency of the wastewater. Embodiment

[0037] Referring to Figure 4 , which is the second embodiment of the present invention. Different from the previous embodiment, the structure of the flocculation component 3 is further optimized in this embodiment, solving the problems of the arrangement of the vibration rod 31 and the difficult adjustment of the vibration efficiency, thereby further improving the flocculation efficiency.

[0038] Specifically, the flocculation component 3 further includes a mounting plate 32 arranged at the inner top of the wastewater tank 11. The outer shape of the mounting plate 32 is a ring. The vibration rod 31 is vertical and its end is connected to the mounting plate 32. The mounting plate 32 enhances the mounting strength between the vibration rod 31 and the wastewater tank 11, and the vertical vibration rod 31 is beneficial for extending into the upper-layer wastewater.

[0039] Furthermore, a fixed sleeve 33 is embedded on the outer wall of the mounting plate 32. There are multiple groups of fixed sleeves 33 and they are equidistantly distributed around the stirring shaft 12. The upper end of the vibration rod 31 is detachably connected to the fixed sleeve 33. The fixed sleeve 33 enhances the connection strength between the vibration rod 31 and the mounting plate 32. The vibration rod 31 is disassembled and assembled with the mounting plate 32 through the fixed sleeve 33. The vibration rod 31 can be replaced with different sizes or different materials, so as to apply different frequencies of vibration to the wastewater.

[0040] Among them, frequency modulation bumps 34 are arranged on the outer surface of the vibration rod 31. There are multiple groups of frequency modulation bumps 34 and they are arranged in an array. The frequency modulation bumps 34 adjust their frequencies by locally changing the mass distribution of the vibration rod 31 to enhance the resonance response. The periodic arrangement of the frequency modulation bumps 34 can guide the vibration wave to propagate along a specific path, reduce energy dissipation, and concentrate energy on the target.

[0041] The remaining structures are the same as those in Embodiment 1.

[0042] During use, first determine the number of vibrating rods 31 required and the bump configuration according to parameters such as the turbidity, organic matter concentration, and oil content of the wastewater, and detachably insert the vibrating rods 31 through the fixed sleeves 33; then start the motor 13 to drive the stirring shaft 12 to strike the vibrating rods 31 of the flocculation assembly 3 through the transmission assembly 4.

[0043] In summary, on the basis of Embodiment 1, Embodiment 2 improves the efficiency of vibration-assisted flocculation through structural innovation of the flocculation assembly 3; firstly, the mounting plate 32 reasonably distributes the forces on each vibrating rod 31, enhancing the mechanical strength and service life of the assembly, enabling the flocculation assembly 3 to remain stable and reliable during long-term operation; secondly, the fixed sleeve 33 enables flexible configuration of the positions and numbers of the vibrating rods 31, allowing the device to quickly adapt to different wastewater characteristics, greatly improving the on-site maintenance and operation efficiency; thirdly, the multi-group array design of the frequency modulation bumps 34 further enhances the microscopic effect of the vibration force, accelerating the contact and aggregation of the flocculant and pollutants, and significantly shortening the reaction time in the flocculation stage. Embodiment

[0044] Refer to Figures 4 to 5 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment further optimizes the structure of the feeding assembly 2. By adding a rotating ring 23 on the top surface of the ratchet disk 21 and cooperating with the mounting plate 32, and opening a material-sprinkling port 24 on the outer wall of the storage barrel 22, batch feeding of the flocculant is achieved, further improving the utilization efficiency of the flocculant in wastewater treatment.

[0045] Specifically, a rotating ring 23 is connected and arranged on the top surface of the ratchet disk 21. The rotating ring 23 is rotatably arranged on the bottom surface of the mounting plate 32. A material-sprinkling port 24 is penetrated and opened on the outer wall of the storage barrel 22. The ratchet disk 21 is supported by the rotating ring 23 and can rotate through the rotating ring 23. The flocculant inside the storage barrel 22 is sprinkled out through the material-sprinkling port 24. The storage barrel 22 drives the internal flocculant to be sprinkled out through the centrifugal force from the material-sprinkling port 24 under the rotation of the ratchet disk 21. Preferably, the material-sprinkling port 24 can be covered with a flexible thin sheet to prevent accidental leakage of the flocculant.

[0046] Furthermore, the top views of the ratchet disk 21 and the storage barrel 22 are both in a circular contour, with a central hole for the stirring shaft 12 to penetrate. The ratchet disk 21 and the stirring shaft 12 are on the same axis. The ratchet disk 21 and the storage barrel 22 do not affect the installation and use of the stirring shaft 12, and at the same time ensure the rotational drive of the ratchet disk 21.

[0047] All other structures are the same as those in Embodiment 2.

[0048] In use, the pawl member 41 drives the ratchet disc 21 to rotate synchronously through the rotating ring 23. The rotating ring 23 rotates smoothly on the bottom surface of the mounting disc 32. The ratchet disc 21 drives the material storage cylinder 22 to rotate. At the same time, the material storage cylinder 22 continuously and evenly sprinkles the flocculant into the tank through the material sprinkling port 24, and further disperses the agent by means of the guiding action of the centrifugal force. This process does not require manual intervention and can achieve full automation of the dosing process.

[0049] In summary, through the further optimization of the feeding assembly 2, precise control and uniform distribution of the flocculant dosing process are achieved. Batch dosing ensures that the concentration of the flocculant can be maintained within the optimal range throughout the reaction process, avoiding the waste of chemicals and low efficiency caused by traditional one-time dosing. Embodiment

[0050] Refer to Figures 3 to 5 , which is the fourth embodiment of the present invention. Different from the previous embodiment, the structure of the transmission assembly 4 is further optimized in this embodiment. Through the innovative design of the pawl member 41, more stable and durable power transmission is achieved, and the vibrating rod 31 obtains more uniform vibration energy.

[0051] Specifically, the transmission assembly 4 further includes a connecting disc 42 connected to the outer wall of the stirring shaft 12. A support seat 43 is provided at the top of the outer end of the connecting disc 42. The pawl member 41 is rotatably arranged at the end of the support seat 43 through a torsion spring. The pawl member 41 is reset and maintained in engagement with the ratchet disc 21 through the torsion spring.

[0052] Furthermore, the connecting disc 42 is located below the bottom surface of the material storage cylinder 22. The outer circumferential surface of the material storage cylinder 22 protrudes from the outer wall of the connecting disc 42. The outer end of the connecting disc 42 for installing the support seat 43 protrudes from the outer circumferential surface of the ratchet disc 21, avoiding interference of the connecting disc 42 with the material sprinkling process of the material storage cylinder 22.

[0053] Preferably, the pawl member 41 includes a pawl head 411 engaged with the ratchet disc 21. The pawl head 411 is rotatably arranged at the end of the support seat 43 through a torsion spring. A tail hammer 412 is provided at the tail end of the pawl head 411. A waveguide pattern 413 is provided on the surface of the tail hammer 412 facing the vibrating rod 31. The innovative design of the tail hammer 412 and the waveguide pattern 413 transforms the traditional "hard impact" into the synergistic effect of "composite vibration - diversion", enabling the vibrating rod 31 to obtain a more uniform vibration energy distribution and effectively avoiding local excessive wear and energy waste.

[0054] All other structures are the same as those in Embodiment 3.

[0055] When in use, the starting motor 13 drives the stirring shaft 12 and the connecting disk 42 to rotate synchronously. The tip of the pawl head 411 presses against the tooth surface of the ratchet disk 21 under the action of the torsion spring preload, and engages to drive the storage barrel 22 to rotate and sprinkle the flocculant; then the tail hammer 412 contacts the vibration rod 31 and guides the vibration rod 31 to vibrate in a directional manner with the waveguide pattern 413, so as to organically combine the vibration energy with the batch addition of flocculant. When the pawl member 41 passes through the vibration rod 31, the pawl head 411 disengages from the ratchet tooth surface, and the storage barrel 22 stops rotating and waits for the next cycle to start again. The whole process does not require manual adjustment, and only regular inspection of the torsion spring preload and the wear of the pawl head 411 is required, thereby ensuring high automation and low maintenance cost of the device.

[0056] In summary, by optimizing the structure of the transmission component 4 and adopting the innovative design of the pawl member 41 supported by a torsion spring, the tail hammer 412 and the waveguide pattern 413, the traditional "hard impact" is transformed into a "compound vibration-flow diversion" synergistic effect, so that the vibration rod 31 obtains a more uniform vibration energy distribution, effectively avoiding local excessive wear and energy waste, and extending the service life of the pawl member 41.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
