Description

Technical Field

[0001] The invention relates to the technical field of waste liquid recovery, in particular to a vitamin K3 waste liquid recovery device with a multi-stage filtering function. Background Art

[0002] During the production process of vitamin K3, a large amount of waste liquid is generated. The waste liquid usually contains more organic matter, derivatives and other substances. Direct discharge of untreated waste liquid not only fails to achieve effective resource recycling, but may also cause environmental pollution.

[0003] In conventional waste liquid recovery devices, only simple filter filtration is used to remove larger particles of impurities, but tiny suspended solids, colloids, and organic matter dissolved in the waste liquid cannot be effectively removed. As a result, the treated waste liquid may still contain a large amount of impurities, and it is impossible to recycle the resources in the waste liquid. At the same time, during the waste liquid treatment process, regardless of the impurity content in the waste liquid, it will be filtered through the same filtration stroke. For waste liquid with less impurities, it may cause a waste of filtration stroke and fail to increase the filtration speed. Summary of the invention

The separation mechanism is used to separate the aqueous solution containing vitamin K3 after filtration, so that vitamin K3 and water are separated, and the water can be reused in the production of vitamin K3 again.

[0007] Furthermore, the main structure includes an installation base, a waste liquid storage tank and a waste liquid output pipe. The waste liquid storage tank is placed on the installation base.

[0009] Further, the multi-stage filtering mechanism includes a primary filtering device, which is connected to the mounting base, the primary filtering device is connected to the waste liquid output pipe, the primary filtering device includes a first filter tank, a first filter screen, a second filter screen and a first liquid outlet pipe, the first filter tank is tightly connected to the mounting base, one end of the waste liquid output pipe away from the waste liquid storage tank is connected to the top of the first filter tank, a first filter cavity is provided in the first filter tank, the first filter screen is connected to the first filter tank, the first filter screen is tightly connected to the inner wall of the first filter cavity, the second filter screen is connected to the first filter tank, the second filter screen is tightly connected to the inner wall of the first filter cavity, one end of the first liquid outlet pipe is connected to the bottom of the first filter tank, the primary filtering device is connected to the path adjustment mechanism, and the first filter tank is connected to the path adjustment mechanism.

[0010] In a multi-stage filtering mechanism, the primary filtering device is used to filter larger impurities or solid particles. The waste liquid is transported from the waste liquid storage tank to the primary filtering device through the waste liquid output pipe and enters the first filter chamber. The first filter chamber is provided with two layers of filter screens. The waste liquid first passes through the first filter screen to filter out larger impurities or solid particles, and then goes down. A path adjustment mechanism is provided between the first filter screen and the second filter screen. If larger impurities or solid particles are filtered out after the waste liquid passes through the first filter screen, they are directly output to the next device through the path adjustment mechanism. If they are not completely filtered out, they continue to go down and pass through the second filter screen for secondary filtration. After completion, they flow out through the first liquid outlet pipe.

[0011] Further, the multi-stage filtering mechanism also includes a secondary filtering device, which is connected to the mounting base, the secondary filtering device is connected to the primary filtering device, the secondary filtering device is connected to the first liquid outlet pipe, the secondary filtering device includes a second filter tank, a first colloid semipermeable membrane, a second colloid semipermeable membrane and a second liquid outlet pipe, the second filter tank is tightly connected to the mounting base, one end of the first liquid outlet pipe away from the first filter tank is connected to the top of the second filter tank, a second filter cavity is provided in the second filter tank, the first colloid semipermeable membrane, the second colloid semipermeable membrane and the second filter tank are connected, the first colloid semipermeable membrane, the second colloid semipermeable membrane and the second filter cavity inner wall are tightly connected, one end of the second liquid outlet pipe is connected to the bottom of the second filter tank, the secondary filtering device is connected to the path adjustment mechanism, and the second filter tank is connected to the path adjustment mechanism.

[0012] In the secondary filtration device, the device is used to filter out small impurities such as colloids and suspended matter in the waste liquid. The waste liquid that has completed the initial filtration flows out through the first liquid outlet pipe to the second filter tank and enters the second filter chamber. The second filter chamber is provided with a first colloid semipermeable membrane and a second colloid semipermeable membrane. The waste liquid first passes through the first colloid semipermeable membrane to filter out small impurities such as colloids and suspended matter in the waste liquid. A path adjustment mechanism is provided between the first colloid semipermeable membrane and the second colloid semipermeable membrane. If the small impurities such as colloids and suspended matter in the waste liquid are filtered out, they will flow directly to the next device through the path adjustment mechanism. If they are not filtered out, they will continue to pass through the second colloid semipermeable membrane for secondary filtration and flow out through the second liquid outlet pipe after completion.

[0013] Furthermore, the multi-stage filtering mechanism also includes a three-stage filtering device, which is connected to the secondary filtering device. The three-stage filtering device includes a third filtering tank, an activated carbon layer, a first microporous filter membrane, a second microporous filter membrane and a third liquid outlet pipe.

The activated carbon layer, the first microporous filter membrane, the second microporous filter membrane and the inner wall of the third filtering cavity are tightly connected. One end of the third liquid outlet pipe is connected to the bottom of the third filtering tank. The three-stage filtering device is connected to the path adjustment mechanism, the third filtering tank is connected to the path adjustment mechanism, the third filtering cavity is connected to the path adjustment mechanism, the three-stage filtering device is connected to the separation mechanism, and the third liquid outlet pipe is connected to the separation mechanism.

[0014] In the three-stage filtration device, the device is used to adsorb small molecules such as pigments and organic matter that may be contained in the raw materials. The waste liquid that completes the secondary filtration flows into the third filter tank through the second liquid outlet pipe and flows into the third filter chamber. The third filter chamber is provided with an activated carbon layer, a first microporous filter membrane and a second microporous filter membrane. The waste liquid first passes through the activated carbon layer, and the activated carbon layer adsorbs the pigment. Then the waste liquid flows downward and passes through the first microporous filter membrane to filter out small molecules such as organic matter. A path adjustment mechanism is provided between the first microporous filter membrane and the second microporous filter membrane. If the first microporous filter membrane filters out small molecules such as organic matter in the waste liquid, it flows directly out to the next device through the path adjustment mechanism. If it is not filtered out, it continues to pass through the second microporous filter membrane for secondary filtration and flows out through the third liquid outlet pipe after completion.

[0015] Further, the path adjustment mechanism includes a detection device, which includes a fixed plate, a first movable plate, a second movable plate, a first return spring and a second return spring. The detection device is provided with three groups, and the three groups of detection devices are respectively placed in the first filter tank, the second filter tank and the third filter tank. The three groups of detection devices are respectively placed between the first filter screen and the second filter screen, the first colloid semipermeable membrane and the second colloid semipermeable membrane, and the first microporous filter membrane and the second microporous filter membrane. The three fixed plates are respectively fastened to the inner walls of the first filter chamber, the second filter chamber and the third filter chamber. A plurality of through holes are provided on the fixed plate, and the through holes of the fixed plate are divided into inner circle through holes and outer circle through holes. The first movable plate, the second movable plate and the fixed plate are slidably connected. The number of the first movable plate and the second movable plate is respectively consistent with the number of the outer circle through holes and the inner circle through holes. Adjacent first movable plates are fastened connected by a connecting rod. One end of the first return spring is connected to the fixed plate, and the other end of the first return spring is connected to the fixed plate. The end is fastened to the first movable plate, the adjacent second movable plate is fastened to the connection rod, one end of the second return spring is connected to the fixed plate, the other end of the second return spring is fastened to the second movable plate, the path adjustment mechanism also includes a conveying device, the conveying device is respectively connected to the first liquid outlet pipe, the second liquid outlet pipe, and the third liquid outlet pipe, the conveying device is connected to the detection device, the conveying device is connected to the fixed plate, the conveying device includes a first intercepting pipe, a second intercepting pipe and a third intercepting pipe, one end of the first intercepting pipe, the second intercepting pipe and the third intercepting pipe are respectively fastened to the three fixed plates, the other ends of the first intercepting pipe, the second intercepting pipe and the third intercepting pipe are respectively connected to the front half of the first liquid outlet pipe, the front half of the second liquid outlet pipe, and the third liquid outlet pipe, one end of the first intercepting pipe, the second intercepting pipe and the third intercepting pipe close to the fixed plate is connected to a pneumatic valve, the conveying device is connected to the separation mechanism, and the third intercepting pipe is connected to the separation mechanism.

[0016] In the path adjustment mechanism, the mechanism is used to adjust the filtering stroke of the waste liquid in the first filter tank, the second filter tank and the third filter tank in real time. When the waste liquid completes one filtration, if the corresponding impurities have been filtered out in the corresponding tank body, the mass of the same amount of waste liquid after filtering is less than the waste liquid that has not completed the corresponding filtration. Therefore, the impact force of the waste liquid falling on the corresponding fixed plate after one filtration is different. The fixed plate is provided with an inner circle through hole and an outer circle through hole, which are respectively covered by the second movable plate and the first movable plate. The second movable plate, the first movable plate and the fixed plate are slidably connected. One of the second movable plates and the first movable plate is provided with a protrusion, the adjacent second movable plates are tightly connected, the adjacent first movable plates are tightly connected, and a second movable plate and a first movable plate are tightly connected by the second return spring, the first return spring and the fixed plate respectively, and the tension degree of the first return spring is higher than that of the second return spring, and The first return spring is shorter than the second return spring, so the first movable plate is easier to move. After the waste liquid completes one filtration, it falls onto the fixed plate, and will impact the protrusions on the first movable plate and the second movable plate. If the waste liquid completes filtration, the filtered waste liquid has a smaller mass and a smaller impact force, so it can only impact and open the second movable plate, but cannot open the first movable plate. At this time, the waste liquid flows out through the corresponding first intercepting pipe, the second intercepting pipe, and the third intercepting pipe to the first liquid outlet pipe, the second liquid outlet pipe, and the third liquid outlet pipe respectively, and enters the next device. If the waste liquid has not completed filtration, due to the large impact, the first movable plate and the second movable plate will be flushed open. At this time, the pneumatic valve is closed, so that the waste liquid cannot flow out from the inner circle through hole, but can only flow out from the outer circle through hole. The waste liquid undergoes a secondary filtration downward, and then flows out to the next device through the corresponding first liquid outlet pipe, the second liquid outlet pipe, and the third liquid outlet pipe.

[0017] Furthermore, the separation mechanism includes a separation tank, a heating plate, an evaporation inclined plate, a water storage tank and an evaporation tank. The third intercepting pipe is connected to the separation tank, the separation tank is fastened to the mounting base, two water storage tanks are provided, the evaporation tank, the water storage tank and the inner bottom wall of the separation tank are fastened, the heating plate is placed at the bottom of the evaporation tank, two evaporation inclined plates are provided, the two evaporation inclined plates are fastened to the inner wall of the separation tank, and the ends of the two evaporation inclined plates that are close to each other are higher than the ends of the two evaporation inclined plates that are far away from each other.

[0018] In the separation mechanism, the mechanism is used to separate the waste liquid after the filtration is completed. At this time, there is only vitamin K3 in the aqueous solution in the waste liquid, which flows into the separation tank through the third liquid outlet pipe and flows into the evaporation tank. The water storage tank and the evaporation tank are both open structures. After that, the heating plate is heated to evaporate the water molecules in the solution. The evaporation rises, and the top of the separation tank is tightly connected with an evaporation inclined plate. The water vapor liquefies after contacting the evaporation inclined plate. The evaporation inclined plate is placed at an angle, and the water storage tank is below the lower end. The liquefied water flows into the water storage tank along the evaporation inclined plate. After completion, the separation of the aqueous solution and vitamin K3 is achieved, and the aqueous solution can be recycled and reused for subsequent vitamin K3 production.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: after the present invention is restarted, by setting a multi-stage filtering mechanism and three filtering devices, different impurities in the waste liquid are separated respectively, which can effectively improve the filtering effect, deeply remove specific impurities, optimize the processing flow, and by setting a path adjustment mechanism, the filtering stroke is adjusted in real time. For the waste liquid that completes the filtering of corresponding impurities in one filtration, since its mass is smaller than that of the waste liquid that fails to complete the filtering in one filtration, the impact force is smaller, and only the second movable plate can be impacted to open, and the first movable plate cannot be opened. At this time, the waste liquid flows out to the first liquid outlet pipe, the second liquid outlet pipe, and the third liquid outlet pipe respectively through the corresponding first intercepting pipe, the second intercepting pipe, and the third intercepting pipe. When entering the next device, if the waste liquid has not been filtered, due to the large impact, the first movable plate and the second movable plate will be flushed open. At this time, the pneumatic valve is closed, so that the waste liquid cannot flow out from the inner circle through holes, and can only flow out from the outer circle through holes. The waste liquid is filtered downward for the second time, and then flows out to the next device through the corresponding first liquid outlet pipe, second liquid outlet pipe, and third liquid outlet pipe. Through such a setting, the filtration efficiency can be improved, the filtration time and useless filtration stroke can be reduced, and the replacement frequency of filter screens, semipermeable membranes, etc. can be reduced. By setting up a separation mechanism, after the waste liquid is filtered, it is composed of only vitamin K3 and aqueous solution. The vitamin K3 and the aqueous solution are separated by the separation mechanism to achieve effective recovery. BRIEF DESCRIPTION OF THE DRAWINGS

The conveying device 32 is connected to the separation mechanism 4, and the third intercepting pipe 323 is connected to the separation mechanism 4.

[0034] In the path adjustment mechanism 3, the mechanism is used to adjust the filtering stroke of the waste liquid in the first filter tank 211, the second filter tank 221 and the third filter tank 231 in real time. When the waste liquid completes one filtration, if the corresponding impurities have been filtered out in the corresponding tank body, the mass of the same amount of waste liquid after filtering is less than that of the waste liquid that has not completed the corresponding filtration. Therefore, the impact force of the waste liquid falling on the corresponding fixed plate 311 after one filtration is different. The fixed plate 311 is provided with an inner circle through hole 3111 and an outer circle through hole 3112, which are respectively passed through the second movable plate 3 13. The first movable plate 312 is covered, and the second movable plate 313, the first movable plate 312 and the fixed plate 311 are slidably connected, one of the second movable plate 313 and the first movable plate 312 is provided with a protrusion, the adjacent second movable plates 313 are fastened and connected, the adjacent first movable plates 312 are fastened and connected, and one second movable plate 313 and one first movable plate 312 are fastened and connected respectively by the second return spring 315, the first return spring 314 and the fixed plate 311, and the tension degree of the first return spring 314 is higher than that of the second return spring 315. 15, and the first return spring 314 is shorter than the second return spring 315, so the first movable plate 312 is easier to move. After the waste liquid is filtered once, it falls on the fixed plate 311, which will impact the protrusions on the first movable plate 312 and the second movable plate 313. If the waste liquid is filtered, the waste liquid after filtering has a small mass and a small impact force, so it can only impact and open the second movable plate 313, and cannot open the first movable plate 312. At this time, the waste liquid passes through the corresponding first intercepting pipe 321, the second intercepting pipe 322, and the third intercepting pipe 331. 23 respectively flows out to the first liquid outlet pipe 214, the second liquid outlet pipe 224, and the third liquid outlet pipe 235, and enters the next device. If the waste liquid has not been filtered, due to the large impact, the first movable plate 312 and the second movable plate 313 will be opened. At this time, the pneumatic valve is closed, so that the waste liquid cannot flow out from the inner circle through hole 3111, and can only flow out from the outer circle through hole 3112. The waste liquid is filtered downward for the second time, and then flows out to the next device through the corresponding first liquid outlet pipe 214, the second liquid outlet pipe 224, and the third liquid outlet pipe 235.

[0035] The separation mechanism 4 includes a separation tank 41, a heating plate 42, an evaporation inclined plate 43, a water storage tank 44 and an evaporation tank 45. The third intercepting pipe 323 is connected to the separation tank 41. The separation tank 41 is fastened to the mounting base 11. Two water storage tanks 44 are provided. The evaporation tank 45, the water storage tank 44 and the inner bottom wall of the separation tank 41 are fastened. The heating plate 42 is placed at the bottom of the evaporation tank 45. Two evaporation inclined plates 43 are provided. The two evaporation inclined plates 43 are fastened to the inner wall of the separation tank 41. The ends of the two evaporation inclined plates 43 that are close to each other are higher than the ends of the two evaporation inclined plates 43 that are far away from each other.

[0036] In the separation mechanism 4, the mechanism is used to separate the waste liquid after the filtration is completed. At this time, there is only vitamin K3 in the aqueous solution in the waste liquid, which flows into the separation tank 41 through the third liquid outlet pipe 235 and flows into the evaporation tank 45. The water storage tank 44 and the evaporation tank 45 are both open structures. Then the heating plate 42 is heated to evaporate the water molecules in the solution. The evaporation rises, and the top of the separation tank 41 is fastened with an evaporation inclined plate 43. The water vapor liquefies after contacting the evaporation inclined plate 43. The evaporation inclined plate 43 is placed at an angle, and the water storage tank 44 is below the lower end. The liquefied water flows into the water storage tank 44 along the evaporation inclined plate 43. After completion, the separation of the aqueous solution and vitamin K3 is achieved, and the aqueous solution can be recycled and reused for subsequent production of vitamin K3.

[0037] Working principle of the present invention: after the present invention is restarted, by setting a multi-stage filtering mechanism 2 and three filtering devices, different impurities in the waste liquid are separated respectively, which can effectively improve the filtering effect, deeply remove specific impurities, optimize the processing flow, and by setting a path adjustment mechanism 3, the filtering stroke is adjusted in real time. For the waste liquid that completes the filtering of corresponding impurities in one filtration, since its mass is smaller than that of the waste liquid that fails to complete the filtering in one time, the impact force is smaller, and only the second movable plate 313 can be impacted to open, and the first movable plate 312 cannot be opened. At this time, the waste liquid flows out to the first liquid outlet pipe 214, the second liquid outlet pipe 224, and the third liquid outlet pipe 235 through the corresponding first intercepting pipe 321, the second intercepting pipe 322, and the third intercepting pipe 323 respectively, and enters the lower In a device, if the waste liquid has not been completely filtered, due to the large impact, the first movable plate 312 and the second movable plate 313 will be flushed open. At this time, the pneumatic valve is closed, so that the waste liquid cannot flow out from the inner circle through hole 3111, and can only flow out from the outer circle through hole 3112. The waste liquid is filtered twice downward, and then flows out to the next device through the corresponding first liquid outlet pipe 214, the second liquid outlet pipe 224, and the third liquid outlet pipe 235. Through such a setting, the filtration efficiency can be improved, the filtration time and useless filtration stroke can be reduced, and the replacement frequency of the filter screen, semipermeable membrane, etc. can be reduced. By setting the separation mechanism 4, after the waste liquid is completely filtered, its composition is only vitamin K3 and aqueous solution. Vitamin K3 and aqueous solution are separated by the separation mechanism 4 to achieve effective recovery.
