Description

Technical Field

[0001] This invention relates to the field of chromium pollution treatment technology, specifically to an apparatus for preparing a network magnetic Fe3O4GOZnO catalyst and its usage method. Background Technology

[0002] With the rapid development of modern industry, environmental and energy crises have become two major challenges facing the world. Environmental issues, in particular, have gradually attracted attention because environmental pollution has already threatened human health. Among these pollutants, heavy metal chromium pollution is one of the most serious due to its widespread industrial use. In addition, pollution from organic dyes has also gradually attracted attention, and many methods have been used to address chromium pollution in wastewater.

[0003] Publication number "CN110652986A" discloses a method for preparing and applying a network magnetic Fe3O4 / GO / ZnO catalyst. The invention involves ultrasonically dispersing graphene oxide in water, adding zinc acetate, ultrasonically stirring, heating, maintaining the temperature, adding NaOH, heating again, maintaining the temperature and stirring, then cooling, adding Fe3O4 nanoparticles, ultrasonically dispersing, adding a silane coupling agent dropwise while stirring, continuously stirring, washing with water under a magnetic field, and vacuum drying to obtain the network magnetic Fe3O4 / GO / ZnO catalyst. This catalyst can produce substances with both oxidizing and reducing properties under visible light, exhibits high reducing power for heavy metal chromium, and significant degradation and removal capabilities for organic matter.

[0004] However, the above solution still has the following drawbacks:

[0005] 1. In step one, FeCl3·6H2O, sodium acetate and 1,6-hexanediamine are dissolved in ethylene glycol and stirred for 1 to 2 hours. The stirring equipment used in this process is often an ordinary stirring tank. However, the stirring method of the stirring tank is singular and can only be stirred in one direction. Therefore, the dissolution time of FeCl3·6H2O, sodium acetate and 1,6-hexanediamine is relatively long, and long-term stirring is required to completely dissolve them in ethylene glycol.

[0006] 2. When stirring FeCl3·6H2O, sodium acetate, and 1,6-hexanediamine in ethylene glycol, these powdered raw materials often enter the mixing tank through the feed inlet. This results in most of the powdered raw materials dissolving in the upper layer of ethylene glycol, making it difficult for them to reach the lower layer. Repeated stirring is required to ensure that the raw materials are evenly dissolved in the ethylene glycol, leading to uneven concentration of raw materials within the ethylene glycol. Summary of the Invention

[0007] The purpose of this invention is to provide an apparatus and a method for preparing a network magnetic Fe3O4GOZnO catalyst, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] An apparatus for preparing a mesh magnetic Fe3O4GOZnO catalyst includes a body, on which a main shaft, a stirring mechanism, a blower mechanism, and a feeding mechanism are mounted. The main shaft is rotatably mounted inside the body, and a base plate is mounted on its top. The main shaft is connected to a motor key fixed to the bottom of the body. The stirring mechanism is located in the middle of the body and is connected to the main shaft. The stirring mechanism is used to uniformly stir the raw materials in the middle of the body. The blower mechanism is located in the upper part of the body and is connected to the main shaft. The blower mechanism is used to agitate the raw materials in the upper part of the body. The bottom of the feeding mechanism is located in the lower part of the body and is connected to the stirring mechanism. The feeding mechanism is used to feed a portion of the raw materials into the bottom of the ethylene glycol section inside the body. The main shaft drives the stirring mechanism and the blower mechanism to operate simultaneously. The stirring mechanism mixes and stirs the raw materials in the middle of the body, and the blower mechanism agitates and stirs the raw materials in the upper part of the body. The stirring mechanism also drives the feeding mechanism to dissolve a portion of the raw materials directly at the bottom of the body, thereby achieving uniform mixing of the raw materials.

[0010] Preferably, the stirring mechanism includes a support, a connecting rod, a stirring blade, and a driving rod. The support is fixed to the surface of the rotating shaft, the connecting rod is movably disposed on the surface of the support, the stirring blade is fixed to the connecting rod, and the driving rod is connected to the machine body through a first driving structure. The bottom of the driving rod is threadedly connected to the connecting rod. The driving rod rotates in both directions under the drive structure. When the driving rod rotates forward, it drives the stirring blade to move downward through the connecting rod. When the driving rod rotates in reverse, it drives the stirring blade to move upward through the connecting rod. Combined with the overall revolution of the stirring blade, the raw material can be uniformly dissolved in ethylene glycol.

[0011] Preferably, the blower mechanism includes a frame, a fixed base, a drive plate, a piston cylinder, a piston rod, a vent hole, and a hose. The frame is fixed to the surface of the main shaft, the fixed base is mounted on the surface of the main shaft, the drive plate is slidably disposed inside the fixed base, and the top end of the drive plate is connected to the machine body through a second drive structure. The piston cylinder is fixed to the side of the fixed base, one end of the piston rod is movably disposed inside the piston cylinder, and the other end of the piston rod is fixed to the surface of the drive plate. The vent hole is disposed on the surface of the main shaft, and the two ends of the hose are respectively connected to the vent hole and the piston cylinder. Driven by the second drive structure, the bottom of the drive plate pulls the piston rod inside the fixed base. At this time, the internal pressure of the piston cylinder decreases, and air enters the piston cylinder through the vent hole and the hose. When the piston rod moves in the opposite direction, it injects the air inside the piston cylinder into ethylene glycol. The airflow causes the liquid inside the machine body to continuously churn.

[0012] Preferably, the feeding mechanism includes a traction frame, a material cylinder, and a material tube. The traction frame is connected to the base plate through a traction structure. The material cylinder is fixed on the traction frame. The material tube extends from the bottom of the material cylinder into the interior and extends to the lower part of the machine body. The traction mechanism drives the traction frame to move horizontally back and forth, and the traction frame drives the material tube to move horizontally back and forth synchronously through the material cylinder.

[0013] Preferably, the first drive structure includes a gear, a gear set, and a reset member. The gear is fixed to the surface of the drive rod and disposed within the base plate. The gear set is fixed to the inner wall of the machine body and engages with the gear. The reset member is disposed between the drive rod and the base plate. When the motor drives the main shaft to rotate, the main shaft drives the gear to revolve through the base plate. When the gear revolve, it engages with the gear set to rotate the drive rod and simultaneously drives the reset member. When the gear disengages from the surface of the gear set, the reset member drives the drive rod to reset.

[0014] Preferably, the second driving structure includes a protrusion, a pressing part, and an elastic element. The protrusion is disposed on the inner wall of the machine body, the pressing part is fixedly connected to one end of the driving plate, and the elastic element is disposed between the driving plate and the base plate. When the main shaft rotates, it drives the pressing part to revolve. After the pressing part is pressed by the protrusion, the elastic element drives the piston rod to move to pump air. After the pressing part of the protrusion finishes pressing the pressing part, the elastic element drives the piston rod to move in the opposite direction to release air.

[0015] Preferably, the traction mechanism includes a locking tooth, a limiting part, and a limiting groove. The locking tooth is disposed on the surface of the traction frame and is connected to the gear. The limiting part is disposed inside the base plate. The limiting groove is disposed on the surface of the traction frame and is connected to the limiting part. The traction frame moves horizontally reciprocatingly through the locking tooth and the gear. The limiting part is always inside the limiting groove during the movement of the traction frame.

[0016] Preferably, the reset component includes a baffle fixed to the top of the drive rod, and a torsion spring fixed between the base plate and the baffle, the torsion spring being sleeved on the surface of the drive rod.

[0017] Preferably, the elastic element includes a through groove on the surface of the frame and a guide rod fixed inside the through groove, one end of the drive plate slides on the surface of the guide rod, and a spring is installed between the drive plate and the through groove.

[0018] This invention also provides a method for using an apparatus for preparing a network magnetic Fe3O4GOZnO catalyst, comprising the following steps:

[0019] S1. The motor drives the main shaft to rotate, and when the main shaft rotates, it drives the base plate to rotate synchronously. At this time, the base plate drives the stirring mechanism to operate, so that the stirring mechanism can evenly stir the raw materials in the middle of the machine body.

[0020] S2. At this time, the substrate can also drive the blower mechanism to operate. The blower mechanism can introduce outside air into the machine body and make the air form an airflow to be released from the inside of the raw material, thereby turning the raw material over for uniform dissolution.

[0021] S3. When the stirring mechanism is in operation, it can drive the feeding mechanism to operate synchronously. The feeding mechanism can stir the raw materials in the lower part of the machine body and send a portion of the raw materials directly into the lower part of the machine body, thereby making the raw materials fully dissolved.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The present invention, through the setting of the stirring mechanism, can stir the raw materials inside the machine body by the stirring blades moving vertically back and forth, and the stirring blades can also revolve under the drive of the main shaft, thereby stirring the raw materials from multiple directions, which can reduce the dissolution time of FeCl3·6H2O, sodium acetate and 1,6-hexanediamine.

[0024] 2. The present invention, through the setting of the blower mechanism, can draw external air into the piston cylinder and release the air into the raw material in the form of airflow under the drive of the second drive structure. The raw material will be agitated after being impacted by the airflow, so that FeCl3·6H2O, sodium acetate and 1,6-hexanediamine can be fully dissolved in ethylene glycol.

[0025] 3. The present invention, through the setting of the feeding mechanism, allows the feed pipe to extend directly into the lower part of the machine body, so that a portion of the raw material can be stored in the feed cylinder and enter the bottom of the machine body directly through the feed pipe. This allows the raw material to be fully dissolved in all parts of the machine body, thereby making the raw material concentration uniform. Combined with the horizontally reciprocating feed pipe, it can further reduce the dissolution time of FeCl3·6H2O, sodium acetate and 1,6-hexanediamine. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please refer to Figure 1-9 The present invention provides an embodiment:

[0038] An apparatus for preparing a mesh magnetic Fe3O4GOZnO catalyst includes a body 1, on which a main shaft 2, a stirring mechanism 5, a blower mechanism 6, and a feeding mechanism 7 are mounted. The main shaft 2 is rotatably mounted inside the body 1, and a base plate 3 is mounted on the top of the main shaft 2. The main shaft 2 is keyed to a motor 4 fixed to the bottom of the body 1. The stirring mechanism 5 is located in the middle of the body 1 and is connected to the main shaft 2. The stirring mechanism 5 is used to uniformly stir the raw materials in the middle of the body 1. The blower mechanism 6 is located in the upper part of the body 1 and is connected to the main shaft 2. The blower mechanism 6 is used to agitate the raw materials in the upper part of the body 1. The bottom of the feeding mechanism 7 is located in the lower part of the body 1 and is connected to the stirring mechanism 5. The feeding mechanism 7 is used to feed part of the raw materials into the bottom of the ethylene glycol in the body 1.

[0039] Please see Figure 1 and 2 The main shaft 2 drives the stirring mechanism 5 and the blowing mechanism 6 to operate simultaneously. The stirring mechanism 5 mixes and stirs the raw materials in the middle of the machine body 1, while the blowing mechanism 6 agitates and stirs the raw materials above the machine body 1. The stirring mechanism 5 also drives the feeding mechanism 7 to operate, allowing some of the raw materials to dissolve directly at the bottom of the machine body 1, thus achieving uniform mixing of the raw materials. Through the stirring mechanism 5, the blowing mechanism 6, and the feeding mechanism 7, the middle, upper, and lower parts of the machine body 1 can be mixed and stirred respectively, so that the raw materials can be uniformly dissolved in ethylene glycol. Furthermore, the feeding mechanism 7 can also directly introduce a portion of the raw materials into the bottom of the machine body 1, which prevents the raw materials from always dissolving in the upper layer of ethylene glycol, thus making the raw material concentration more uniform.

[0040] The stirring mechanism 5 includes a support 501, a connecting rod 502, a stirring blade 503, and a drive rod 504. The support 501 is fixed to the surface of the rotating shaft, the connecting rod 502 is movably disposed on the surface of the support 501, the stirring blade 503 is fixed to the connecting rod 502, and the drive rod 504 is connected to the machine body 1 through a first drive structure 8. The bottom of the drive rod 504 is threadedly connected to the connecting rod 502. The drive rod 504 rotates forward and backward under the drive structure. When the drive rod 504 rotates forward, it drives the stirring blade 503 to move downward through the connecting rod 502. When the drive rod 504 rotates backward, it drives the stirring blade 503 to move upward through the connecting rod 502. With the overall revolution of the stirring blade 503, the raw materials can be uniformly dissolved in ethylene glycol.

[0041] The first drive structure 8 includes a gear 801, a gear set 802, and a reset member 11. The gear 801 is fixed to the surface of the drive rod 504 and disposed within the base plate 3. The gear set 802 is fixed to the inner wall of the body 1 and is connected to the gear 801. The reset member 11 is disposed between the drive rod 504 and the base plate 3. When the motor 4 drives the main shaft 2 to rotate, the main shaft 2 drives the gear 801 to revolve through the base plate 3. When the gear 801 revolves, it cooperates with the gear set 802 to rotate the drive rod 504 and simultaneously drives the reset member 11. When the gear 801 disengages from the surface of the gear set 802, the reset member 11 drives the drive rod 504 to reset. The reset member 11 includes a baffle 1101 fixed to the top of the drive rod 504 and a torsion spring 1102 fixed between the base plate 3 and the baffle 1101. The torsion spring 1102 is sleeved on the surface of the drive rod 504.

[0042] Please see Figure 6 and 7 The main shaft 2 drives the base plate 3 to rotate, and the base plate 3 can drive the drive rod 504 and the gear 801 to rotate synchronously. The gear 801 can rotate on its own axis on the surface of the gear set 802 while revolving around the central axis. The gear 801 can drive the drive rod 504 to rotate. When the drive rod 504 rotates, it can drive the connecting rod 502 to move up on its surface, so that the connecting rod 502 drives the stirring blade 503 to move up synchronously. At this time, the gear teeth can drive the torsion spring 1102 to deform and store energy through the baffle 1101 at the top of the drive rod 504. When the gear 801 disengages from the surface of the gear set 802... After separation, the torsion spring 1102 resets and releases energy to drive the drive rod 504 to rotate in the opposite direction. At this time, the drive rod 504 can drive the connecting rod 502 to move downward on its surface, thereby driving the stirring blade 503 to move downward synchronously through the connecting rod 502. During the vertical reciprocating movement, the stirring blade 503 can also revolve under the drive of the substrate 3, thereby uniformly stirring and mixing the raw materials. Through the above process, the vertical reciprocating movement of the stirring blade 503 combined with the revolution of the stirring blade 503 can stir the raw materials from multiple directions, thereby making the raw materials more uniformly mixed.

[0043] The blower mechanism 6 includes a frame 601, a fixed base 602, a drive plate 603, a piston cylinder 604, a piston rod 605, a vent 606, and a hose 607. The frame 601 is fixed to the surface of the main shaft 2, the fixed base 602 is mounted on the surface of the main shaft 2, the drive plate 603 is slidably disposed inside the fixed base 602, and the top end of the drive plate 603 is connected to the body 1 through a second drive structure 9. The piston cylinder 604 is fixed to the side of the fixed base 602, one end of the piston rod 605 is movably disposed inside the piston cylinder 604, and the other end of the piston rod 605 is fixed. On the surface of the drive plate 603, a vent 606 is provided on the surface of the main shaft 2. The two ends of the hose 607 are respectively connected to the vent 606 and the piston cylinder 604. Under the drive of the second drive structure 9, the bottom of the drive plate 603 pulls the piston rod 605 inside the fixed seat 602. At this time, the internal pressure of the piston cylinder 604 decreases, and air enters the piston cylinder 604 through the vent 606 and the hose 607. When the piston rod 605 moves in the opposite direction, it injects the air inside the piston cylinder 604 into ethylene glycol. The liquid inside the machine body 1 is continuously agitated by the power of the airflow.

[0044] The second drive structure 9 includes a protrusion 901, a pressing part 902, and an elastic element 12. The protrusion 901 is disposed on the inner wall of the machine body 1. The pressing part 902 is fixedly connected to one end of the drive plate 603. The elastic element 12 is disposed between the drive plate 603 and the base plate 3. When the main shaft 2 rotates, it drives the pressing part 902 to revolve. After the pressing part 902 is pressed by the protrusion 901, the elastic element 12 drives the piston rod 605 to move to pump air. After the pressing part 902 is finished, the elastic element 12 drives the piston rod 605 to move in the opposite direction to release air. The elastic element 12 includes a through groove 1201 opened on the surface of the frame 601 and a guide rod 1202 fixed inside the through groove 1201. One end of the drive plate 603 slides on the surface of the guide rod 1202. A spring 1203 is installed between the drive plate 603 and the through groove 1201.

[0045] Please see Figure 3 , 4When the main shaft 2 drives the frame 601 to rotate, it can drive the extrusion section 902 to rotate synchronously via the drive plate 603. Since the protrusion 901 is fixed, when the extrusion section 902 rotates, the spring 1203 will not be compressed in the gap between the two protrusions 901. However, when the extrusion section 902 continues to rotate and contacts a single protrusion 901, the spring 1203 can be compressed. Under the above conditions, the spring 1203 can complete the entire process of compression and reset. Therefore, the drive plate 603 can perform horizontal reciprocating movement under the drive of the spring 1203. During operation, the piston rod 605 can be driven to move synchronously. When the piston rod 605 is pulled inside the piston cylinder 604, the pressure inside the piston cylinder 604 decreases, and air enters the piston cylinder 604 through the through hole and the hose 607. When the piston rod 605 is pushed inside the piston cylinder 604, the air inside the piston cylinder 604 can enter the machine body 1. During this process, one-way valves need to be installed at the outlet end of the piston cylinder 604 and on the hose 607 to control the direction of airflow. Through the above process, the raw materials inside the machine body 1 can be turned over by the airflow, which can make the raw materials mix more evenly.

[0046] The feeding mechanism 7 includes a traction frame 701, a material cylinder 702, and a material tube 703. The traction frame 701 is connected to the base plate 3 through a traction structure. The material cylinder 702 is fixed on the traction frame 701. The material tube 703 extends from the bottom of the material cylinder 702 into the interior and extends to the lower part of the machine body 1. The traction mechanism 10 drives the traction frame 701 to move horizontally back and forth, and then the traction frame 701 drives the material tube 703 to move horizontally back and forth synchronously through the material cylinder 702.

[0047] The traction mechanism 10 includes a locking tooth 1001, a limiting part 1002, and a limiting groove 1003. The locking tooth 1001 is disposed on the surface of the traction frame 701 and is connected to the gear 801. The limiting part 1002 is disposed inside the base plate 3. The limiting groove 1003 is disposed on the surface of the traction frame 701 and is connected to the limiting part 1002. The traction frame 701 moves horizontally reciprocatingly through the locking tooth 1001 and the gear 801. The limiting part 1002 is always inside the limiting groove 1003 during the movement of the traction frame 701.

[0048] Please see Figure 8 and 9Since gear 801 can reciprocate during revolution, gear 801 can drive traction frame 701 to reciprocate horizontally through snap tooth 1001. Traction frame 701 can drive material cylinder 702 and material tube 703 to reciprocate horizontally synchronously. The bottom end of material tube 703 extends directly into the lower part of machine body 1. Therefore, material tube 703 can not only stir the raw material, but also move the raw material to different parts for dissolution. The limiting part 1002 and limiting groove 1003 cooperate to ensure that traction frame 701 always moves horizontally, thereby ensuring precise meshing between snap tooth 1001 and gear 801.

[0049] This invention also provides a method for using an apparatus for preparing a network magnetic Fe3O4GOZnO catalyst, comprising the following steps:

[0050] S1. Motor 4 drives main shaft 2 to rotate. When main shaft 2 rotates, it drives base plate 3 to rotate synchronously. At this time, base plate 3 drives stirring mechanism 5 to operate, so that stirring mechanism 5 can uniformly stir raw materials in the middle of machine body 1.

[0051] S2, the substrate 3 can also drive the blower mechanism 6 to operate. The blower mechanism 6 can introduce outside air into the machine body 1 and make the air form an airflow to be released from the inside of the raw material, thereby turning the raw material over for uniform dissolution.

[0052] S3. When the stirring mechanism 5 is in operation, it can drive the feeding mechanism 7 to operate synchronously. The feeding mechanism 7 can stir the raw materials in the lower part of the machine body 1 and send a portion of the raw materials directly into the lower part of the machine body 1, so that the raw materials can be fully dissolved.

[0053] It should be noted that the motor 4 is a device or equipment existing in the prior art, or a device or equipment that can be implemented by the prior art, and the principle of the motor 4 is clear to those skilled in the art, so it will not be described in detail.
