Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a wastewater recycling system for sesame oil production. Background Technology

[0002] Water plays a crucial role in many processes of sesame oil production, such as cleaning raw materials, using water flow to wash away dust, dirt, microorganisms and some impurities from the surface of sesame seeds, and adding boiling water to the ground sesame paste, taking advantage of the fact that sesame protein is more hydrophilic than lipophilic, causing the protein to absorb water and swell, displacing the oil from the protein membrane. Water flow is an indispensable substance in the sesame oil production process.

[0003] Different sesame oil production processes have different requirements for water quality. Therefore, after each process, the water used is either discharged or treated directly. For example, when washing sesame seeds, the raw material for sesame oil, the water becomes turbid and turns black or dark brown due to the dissolution of natural pigments from the sesame seed skin and the suspension of dirt and dust. It also contains a large amount of organic matter, suspended solids, and oil. Therefore, the wastewater is usually treated in multiple stages, including physical, chemical, and biological treatment. Physical treatment involves using filtration units to filter out large particulate impurities in the wastewater, then adding chemical agents to treat the wastewater, and finally removing organic matter through biological processes, thus allowing the treated wastewater to be recycled.

[0004] In chemical treatment, pumps are usually manually controlled or chemicals are directly poured in, relying on the experience of the staff or pre-weighing and mixing the chemicals. However, during wastewater treatment and transportation, there is often a certain quantity difference, which can lead to excessive chemical dosage, resulting in increased treatment costs, or insufficient dosage, resulting in incomplete chemical treatment. It is impossible to dynamically adjust the amount of chemicals added based on the real-time flow of wastewater. Furthermore, the chemicals and wastewater are mostly statically mixed through pipelines, which can easily lead to localized excessively high or low chemical concentrations, reducing the efficiency of chemical treatment and increasing the load on subsequent biochemical treatment. Therefore, a wastewater recycling system for sesame oil production is designed to solve or alleviate the above problems. Summary of the Invention

[0037] A drive shaft is vertically and rotatably mounted inside the mounting cylinder via a first shaft seat and a second shaft seat. A drive source for driving the drive shaft to rotate is installed at the bottom of the inner cavity of the base housing.

[0038] A drive swashplate is fixedly installed on the outside of the drive shaft. The drive swashplate has two sides, one high and one low. Each point on the side of the drive swashplate is equidistant from the center line of the drive shaft.

[0039] The guide post is slidably connected to the outside of the first shaft seat. The plunger is fixedly installed on the top of the guide post. A connector is fixedly connected to the bottom of the guide post. The connector is slidably engaged with the side of the drive swashplate.

[0040] An electromagnetic sensor is fixedly installed at the bottom of the first bearing seat. When the high end of the drive swashplate presses against the electromagnetic sensor, the electromagnetic sensor generates an electrical signal to provide feedback on the rotation frequency signal of the drive swashplate.

[0041] Preferably, the mounting component includes:

[0042] A supporting ring is fixedly installed on the top of the support base;

[0043] The first flange plate and the first bolt are fixedly sleeved on the bottom of the mounting cylinder. The first bolt passes through the top of the first flange plate and is threaded to the support ring via the second bearing.

[0046] Preferably, the control unit performs the full-stroke status determination by including the following steps:

[0047] The flow rate of the liquid medicine discharged from the delivery pipe is collected by a flow meter, and the electrical signal transmitted by the electromagnetic sensor is processed to obtain the frequency of the drive plate to rotate at its highest point.

[0048] Based on the standard mixing ratio of the drug solution and wastewater, compare the discharge flow rate of the delivery pipe with the wastewater transport flow rate inside the flow channel. If the ratio of the discharge flow rate of the delivery pipe to the wastewater transport flow rate inside the flow channel is less than the standard mixing ratio of the drug solution and wastewater, increase the frequency of the drive source driving the high point of the drive swashplate through the drive shaft until the ratio of the discharge flow rate of the delivery pipe to the wastewater transport flow rate inside the flow channel equals the standard mixing ratio of the drug solution and wastewater. If the ratio of the discharge flow rate of the delivery pipe to the wastewater transport flow rate inside the flow channel is greater than the standard mixing ratio of the drug solution and wastewater, decrease the frequency of the drive source driving the high point of the drive swashplate through the drive shaft until the ratio of the discharge flow rate of the delivery pipe to the wastewater transport flow rate inside the flow channel equals the standard mixing ratio of the drug solution and wastewater.

[0049] Based on one rotation cycle of the drive swashplate, the pistons inside the cylinder discharge the rated flow rate. Combined with the liquid flow rate inside the delivery pipe, the operating conditions of the components on the cylinder are assessed. It is determined whether the rotation frequency of the drive swashplate at its highest point is proportional to the rated flow rate of the liquid inside the delivery pipe. When it is proportional, the components on the cylinder operate normally. When it is lower than the rated ratio, and the rated flow rate of the liquid inside the delivery pipe decreases proportionally within a fixed time period within one rotation cycle of the drive swashplate, the pistons performing work during that time period and the flow restrictors on their corresponding inlets discharge... If a fault is detected, mark the fault information and increase the frequency of the drive swashplate rotation at its highest point so that the ratio of the liquid discharge flow rate in the delivery pipe to the wastewater transport flow rate in the flow channel within one cycle equals the standard mixing ratio of the liquid medicine and wastewater. If the drive swashplate is running normally but there is no liquid flow inside the delivery pipe, check if there is still liquid medicine inside the plastic tank. If there is still liquid medicine inside the plastic tank, it is determined that the flow-gathering chamber and its internal flow-limiting components are faulty, and the machine is stopped for repair. If there is no liquid medicine inside the plastic tank, stop the mixing and transport of liquid medicine and wastewater, and add liquid medicine to the plastic tank.

[0050] The technical effects and advantages of this invention are as follows:

[0051] (1) The present invention utilizes the combined use of container components, discharging components, channel components and driving components. Under the action of the driving component, the discharging component can transport the liquid medicine inside the container component to the inside of the flow channel through the channel component, so that the wastewater and liquid medicine are mixed in proportion and discharged in the flow channel. Furthermore, based on the information fed back by the channel component and the driving component, the equipment can be judged for the entire process operation in order to accurately control the proportional mixing of liquid medicine and wastewater.

[0052] (2) The present invention utilizes the setting method of the drive swashplate, where the vertical distance between each edge of the drive swashplate and the center line of the transmission shaft is the same. When the mounting shaft drives the drive swashplate to rotate, the drive swashplate can drive multiple plungers to reciprocate inside the cylinder through multiple connectors and guide pillars, thereby continuously pulsatingly discharging the liquid medicine from the channel component. Furthermore, by using the feedback of the drive swashplate rotation frequency and the liquid medicine delivery rate, the liquid medicine discharge flow rate can be adjusted in real time. In addition, the working status of the entire process of the discharging component can be judged in real time, which can help identify the fault of the discharging component and improve the convenience of its maintenance.

[0053] (3) The present invention utilizes the combination of a liquid distribution plate, a liquid delivery pipe, a flow meter, a threaded ring, a sealing cap, and a flow limiting device. The flow limiting device can make the liquid inlet hole on the liquid distribution plate only allow liquid to enter but not exit, and the liquid outlet hole only allow liquid to exit but not enter. Furthermore, the threaded ring and the sealing cap can form a flow-gathering chamber on the top of the liquid distribution plate. When the liquid medicine inside the cylinder enters the flow-gathering chamber through the liquid outlet hole, it can flow through the liquid outlet hole into the liquid delivery pipe, thereby being transported to the inside of the flow channel to achieve the mixing of the liquid medicine and the wastewater.

[0065] 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.

[0066] This invention provides, for example Figures 1-9 The wastewater recycling system for sesame oil production shown includes a treatment tank 1, a base shell 2, a container component 3, a channel component 45, and a drive component 46. The treatment tank 1 is used for multi-stage treatment and recycling of wastewater. The treatment tank 1 is internally divided into multiple chambers corresponding to different wastewater treatment processes, which is existing technology and will not be described in detail here. A transfer pump is installed on the treatment tank 1 to treat the wastewater inside, thus treating and recycling the wastewater generated during sesame oil production. The container component 3 is installed on the treatment tank 1 via the base shell 2. The container component 3 is used to store chemicals for the chemical treatment of the wastewater. The base shell 2 contains... There is a discharge assembly 4 for discharging the liquid medicine and wastewater from the container component 3 in a proportional manner. A channel component 45 is installed on the discharge assembly 4. The channel component 45 is used to transport and mix the liquid medicine discharged from the discharge assembly 4 with the wastewater. This not only ensures that the wastewater and medicine are mixed and transported in proportion, but also improves the uniformity of the mixing of wastewater and medicine and reduces the time of subsequent stirring treatment. A drive component 46 is installed on the base housing 2. The drive component 46 drives the discharge assembly 4 to move periodically. The drive component 46 is connected to a control unit. The control unit judges the status of the discharge assembly 4 throughout its entire stroke by using the frequency signal fed back by the drive component 46 and the flow rate signal fed back by the channel component 45.

[0067] Specifically, container component 3 includes a plastic box 31, a restraining frame 32, an end cap 33, a support base 34, and a flow channel 35. The plastic box 31 is fixedly installed on the top of the base housing 2 via the restraining frame 32. Figure 2 As shown, the restraint frame 32 is wrapped around the outside of the plastic box 31. The bottom of the restraint frame 32 is fixedly connected to the base housing 2 by bolts. Therefore, the restraint frame 32 ensures the stability of the plastic box 31 mounted on the base housing 2. A liquid level sensor can also be installed inside the plastic box 31 to monitor the amount of liquid medicine inside in real time. The end cap 33 is threaded onto the top of the plastic box 31. The bottom of the plastic box 31 has an opening corresponding to the medicine discharge assembly 4, and the diameter of the opening is smaller than the diameter of the end cap 33. Therefore, when the end cap is opened... When the cover 33 is in place, the discharge assembly 4 connected to the bottom can be disassembled and maintained through the feed port at the top of the plastic box 31. The flow channel 35 is fixedly installed inside the base housing 2 through the support 34. The flow channel 35 is used to provide a channel for mixing wastewater and medicine. When the wastewater inside the treatment tank 1 is chemically treated, the pump on the treatment tank 1 outputs the wastewater from the flow channel 35. A stirring rod can also be installed inside the flow channel 35 to run synchronously with the drive component 46, stirring and mixing the medicine and wastewater entering the flow channel 35 before discharge.

[0068] Furthermore, the discharging assembly 4 includes a mounting cylinder 41, a mounting component 42, a cylinder 43, and a plunger 44. The mounting cylinder 41 is vertically mounted on the top of the support base 34 via the mounting component 42. The channel component 45 is mounted between the mounting cylinder 41 and the plastic housing 31 via the mounting component 42. The cylinder 43 is fixedly mounted on the top of the inner cavity of the mounting cylinder 41. The plunger 44 is slidably sleeved inside the cylinder 43. Figure 4 and Figure 8 As shown, there can be four plungers 44 installed inside the cylinder 43. When the drive component 46 runs one revolution, the four plungers 44 on the cylinder 43 perform one up-and-down liquid suction and discharge operation in sequence. The total discharge volume in a single cycle is four times the discharge volume of a single plunger 44. The drive component 46 is used to drive the plungers 44 to move up and down inside the cylinder 43, so that the plungers 44 cooperate with the channel component 45 to periodically discharge the drug.

[0069] Furthermore, the channel component 45 includes a liquid distribution plate 451, a liquid inlet 452, a liquid outlet 453, a flow restrictor, a flow convergence chamber, a liquid drain 454, and a liquid delivery pipe 456. The liquid distribution plate 451 is fixedly installed between the cylinder body 43 and the plastic housing 31 via the mounting component 42. Figure 4As shown, both the inlet port 452 and the outlet port 453 are located on the distribution plate 451. The distance from the inlet port 452 to the center of the distribution plate 451 is greater than the distance from the outlet port 453 to the center of the distribution plate 451. The number of inlet ports 452 and outlet ports 453 on the distribution plate 451 is the same as the number of plungers 44 on the cylinder block 43, and one plunger 44 corresponds to one inlet port 452 and one outlet port 453. Flow limiting components are installed on the top of the distribution plate 451. The flow limiting components are used for... The inlet port 452 allows liquid to flow in but not out, while the flow restrictor prevents liquid from flowing out of the outlet port 453. Specifically, when the plunger 44 descends inside the cylinder 43, the flow restrictor seals the outlet port 453. As the plunger 44 descends, the corresponding chamber inside the cylinder 43 is under negative pressure, allowing liquid to be drawn from the plastic casing 31 through the inlet port 452. When the plunger 44 rises inside the cylinder 43, the flow restrictor seals the inlet port 452, and the rising plunger 44 draws liquid from the corresponding chamber inside the cylinder 43. The liquid medicine in the chamber is discharged into the converging chamber through the outlet hole 453. The converging chamber is located at the top of the distribution plate 451 and is used to collect and discharge the liquid medicine discharged from the outlet hole 453 on the distribution plate 451. The drain hole 454 is vertically located in the middle of the distribution plate 451 and the cylinder body 43, and the inner cavity of the drain hole 454 is connected to the converging chamber. One end of the delivery pipe 456 is fixedly installed at the bottom of the cylinder body 43, and the inner cavity of the delivery pipe 456 is connected to the drain hole 454. The inner cavity is connected, and the other end of the liquid delivery pipe 456 is installed at the liquid inlet of the flow channel 35. A flow meter 457 for flow detection is installed on the liquid delivery pipe 456. When the liquid in the inner cavity of the cylinder 43 is injected into the flow-gathering chamber in sequence, it can then flow into the flow channel 35 through the drain hole 454 and the liquid delivery pipe 456. The flow meter 457 can detect the liquid flow rate inside the liquid delivery pipe 456 in real time, and the flow rate of wastewater inside the flow channel 35 is determined by the power of the wastewater transfer pump.

[0070] Furthermore, the flow-gathering chamber includes a threaded ring 458 and a sealing cap 459. The threaded ring 458 is fixedly connected to the top of the liquid distribution plate 451. The flow-limiting element at the top of the liquid distribution plate 451 is located inside the threaded ring 458. The sealing cap 459 is threaded onto the outside of the threaded ring 458. The chamber between the sealing cap 459 and the threaded ring 458 is used for the convergence and discharge of the liquid discharged from the outlet hole 453. That is, the threaded ring 458 and the sealing cap 459 enclose multiple outlet holes 453 at the top of the liquid distribution plate 451, so that the liquid discharged from multiple chambers inside the cylinder 43 flows back to the inside of the sealing cap 459 and is then discharged through the outlet hole 453.

[0071] Furthermore, the flow-limiting component includes a connecting sleeve 4510, a flow-limiting valve disc 4511, an elastic element 4512, and a limiting block 4513. The end of the connecting sleeve 4510 is fixedly connected to the liquid distribution tray 451. The flow-limiting valve disc 4511 is sleeved inside the connecting sleeve 4510, with one side of the flow-limiting valve disc 4511 in contact with the liquid distribution tray 451. The elastic element 4512 is fixedly installed on the side of the flow-limiting valve disc 4511 facing away from the liquid distribution tray 451, and one end of the elastic element 4512 is fixedly installed inside the connecting sleeve 4510. Figure 6 As shown, when the plunger 44 moves downward inside the cylinder 43, and the chamber inside the cylinder 43 is under negative pressure, the elastic element 4512 and the flow-limiting valve 4511 corresponding to the top of the outlet hole 453 can block and seal the outlet hole 453. Meanwhile, under negative pressure, the flow-limiting valve 4511 at the bottom of the inlet hole 452 can squeeze the elastic element 4512 to bend, thus opening the inlet hole 452. This allows the cylinder 43 to extract the liquid from the plastic box 31 under the action of the plunger 44. When the plunger 44 rises inside the cylinder 43, putting the chamber inside the cylinder 43 under positive pressure, the inlet hole 452... The flow-limiting valve disc 4511 at the bottom of 52 is squeezed and sealed against the liquid inlet 452, and the liquid inside the cylinder 43 can be discharged through the flow-limiting valve disc 4511 on the liquid outlet 453. The limiting block 4513 is fixedly connected to the inner wall of the connecting sleeve 4510. The limiting block 4513 is used to limit the angle at which the flow-limiting valve disc 4511 tilts and opens. The limiting block 4513 can limit the bending angle of the elastic element 4512, so as to avoid the flow-limiting valve disc 4511 from rotating and opening too much, which would cause the elastic element 4512 to bend too much and thus prevent the elastic element 4512 from being able to drive the flow-limiting valve disc 4511 to reset.

[0072] Specifically, the drive component 46 includes a first bearing 461, a second bearing 462, a drive shaft 463, a drive swashplate 464, a guide post 465, and an electromagnetic sensor 467. The first bearing 461 is fixedly installed inside the mounting cylinder 41. The second bearing 462 is installed between the mounting cylinder 41 and the support base 34 via the mounting component 42. The drive shaft 463 is vertically rotatably installed inside the mounting cylinder 41 via the first bearing 461 and the second bearing 462. A drive source for driving the drive shaft 463 is installed at the bottom of the inner cavity of the base housing 2. The drive source consists of a servo motor, a gearbox, and a shaft. The shaft is vertically installed in the flow channel 35. The servo motor is connected to the drive shaft 463 via the gearbox and the shaft to control the speed of the servo motor. This allows control of the rotational speeds of the drive shaft 463 and the drive swashplate 464. The drive swashplate 464 is fixedly mounted on the outside of the drive shaft 463. The drive swashplate 464 has high and low ends on both sides. The vertical distance between each point on the side of the drive swashplate 464 and the axis of the drive shaft 463 is the same, meaning the projection of the drive swashplate 464 onto the axis of the drive shaft 463 is circular. The guide post 465 is slidably connected to the first bearing 461. The plunger 44 is fixedly mounted on the top of the guide post 465, and the side of the guide post 465 has protrusions to ensure the stability of the guide post 465 as it slides vertically up and down on the first bearing 461. A connector 466 is fixedly connected to the bottom of the guide post 465, and the connector 466 is slidably engaged with the side of the drive swashplate 464. The drive swashplate 464 is divided into high and low ends on both sides. Each point on the side of the drive swashplate 464 is perpendicular to the axis of the drive shaft 463. When the drive shaft 463 drives the drive swashplate 464 to rotate, the side with the height difference of the drive swashplate 464 can drive the guide pins 465 to move up and down through the connector 466, thereby causing the plunger 44 to move up and down inside the cylinder block 43. This ensures that the points on the side of the drive swashplate 464 and the connection point of the connector 466 are always aligned vertically, thus guaranteeing the stability of the drive swashplate 464 driving the multiple guide pins 465 to move up and down. An electromagnetic sensor 467 is fixedly installed at the bottom of the first bearing 461. When the high end of the drive swashplate 464 presses against the electromagnetic sensor 467, the electromagnetic sensor 467 generates an electrical signal. The electromagnetic sensor 467, used to provide feedback on the rotation frequency signal of the drive swashplate 464, consists of an electromagnetic rod, a coil, and a return spring. The electromagnetic rod is sleeved inside the coil. When the high side of the drive swashplate 464 moves to the bottom of the electromagnetic sensor 467, the drive swashplate 464 can squeeze the electromagnetic rod to move inside the coil, thereby generating an electrical signal inside the coil. The high side of the drive swashplate 464 then separates from the electromagnetic sensor 467, and the return spring can squeeze the electromagnetic rod to descend and reset. By processing the electrical signal, the frequency of the high point movement of the drive swashplate 464 can be obtained. The time difference between two signal transmissions from the electromagnetic sensor 467 represents one rotation cycle of the drive swashplate 464, during which the piston 44 inside the cylinder 43 performs one work operation.The higher the frequency of the high-point movement of the drive swashplate 464, the higher the rotation speed of the drive swashplate 464, and the shorter the cycle time of the drive swashplate 464. Furthermore, based on the number of plungers 44 inside the cylinder block 43, a cycle of the drive swashplate 464 can be equally divided. Each time segment within a cycle corresponds to a plunger 44 inside the cylinder block 43, and a marking signal is assigned to the corresponding plunger 44 to facilitate subsequent fault repair based on the corresponding marking.

[0073] Specifically, the mounting component 42 includes a supporting ring 421, a first flange plate 422, a first bolt, a second flange plate 423, a third flange plate 424, and a second bolt. The supporting ring 421 is fixedly mounted on the top of the support base 34. The first flange plate 422 is fixedly sleeved on the bottom of the outside of the mounting cylinder 41. The first bolt passes through the top of the first flange plate 422 and is threadedly connected to the supporting ring 421 via the second shaft seat 462. By removing the first bolt, the mounting cylinder 41 and the second shaft seat 462 can be disassembled and maintained. The second flange plate 423 is fixedly sleeved on the top of the outer wall of the mounting cylinder 41. The third flange plate 424 is pressed against the plastic... At the bottom of the inner wall of the housing 31, the second bolt passes through the top of the third flange plate 424, through the plastic housing 31 and the liquid distribution tray 451, and is threaded to the second flange plate 423. A sealing gasket is installed between the liquid distribution tray 451 and the cylinder 43 to ensure the seal between the liquid distribution tray 451 and the cylinder 43. Gaskets are also installed on the side of the liquid distribution tray 451 and the third flange plate 424 facing the plastic housing 31 to ensure the seal between them and the plastic housing 31. The second bolt is treated with anti-rust spraying. The diameter of the third flange plate 424 is smaller than the diameter of the feed inlet at the top of the plastic housing 31, so that the third flange plate 424 can be installed or removed.

[0074] In particular, the control unit performs the following steps to determine the status throughout the entire stroke:

[0075] The flow rate information of the liquid medicine discharged from the liquid delivery pipe 456 is collected by the flow meter 457, and the electrical signal transmitted by the electromagnetic sensor 467 is processed to obtain the frequency of the drive plate 464 to rotate at its highest point.

[0076] Based on the standard mixing ratio of liquid medicine and wastewater, compare the discharge flow rate of liquid delivery pipe 456 with the wastewater transport flow rate inside flow channel 35. If the ratio of the discharge flow rate of liquid delivery pipe 456 to the wastewater transport flow rate inside flow channel 35 is less than the standard mixing ratio of liquid medicine and wastewater, increase the frequency at which the drive source drives the high point of drive swashplate 464 through drive shaft 463 until the ratio of the discharge flow rate of liquid delivery pipe 456 to the wastewater transport flow rate inside flow channel 35 equals the standard mixing ratio of liquid medicine and wastewater. If the ratio of the discharge flow rate of liquid delivery pipe 456 to the wastewater transport flow rate inside flow channel 35 is greater than the standard mixing ratio of liquid medicine and wastewater, decrease the frequency at which the drive source drives the high point of drive swashplate 464 through drive shaft 463 until the ratio of the discharge flow rate of liquid delivery pipe 456 to the wastewater transport flow rate inside flow channel 35 equals the standard mixing ratio of liquid medicine and wastewater.

[0077] According to the rotation cycle of the drive swashplate 464, the plunger 44 inside the cylinder 43 operates and discharges the rated flow. Combined with the liquid flow rate inside the liquid delivery pipe 456, the operating conditions of the components on the cylinder 43 are judged. It is determined whether the rotation frequency of the drive swashplate 464 at its highest point is proportional to the rated flow rate of the liquid inside the liquid delivery pipe 456. When it is proportional, the components on the cylinder 43 operate normally. When it is lower than the rated ratio, and when the rated flow rate of the liquid inside the liquid delivery pipe 456 decreases proportionally, and this occurs within a fixed time period within one rotation cycle of the drive swashplate 464, then the plunger 44 performing work during that time period and the flow-limiting device on its corresponding inlet port 452 malfunction, and fault information is marked. Record the marked signal on the corresponding plunger 44 within the corresponding time period, and then handle the fault by increasing the frequency of the high point rotation of the drive swash plate 464 so that the ratio of the liquid discharge flow rate of the liquid delivery pipe 456 to the wastewater delivery flow rate inside the flow channel 35 within one cycle is equal to the standard mixing ratio of the medicine and wastewater. When the drive swash plate 464 is running normally, but there is no liquid flow inside the liquid delivery pipe 456, check whether there is still medicine inside the plastic box 31. If there is still medicine inside the plastic box 31, it is determined that the flow-gathering chamber and its internal flow-limiting device are faulty, and the machine is stopped for repair. When there is no medicine inside the plastic box 31, stop the mixing and delivery of medicine and wastewater, and add medicine to the plastic box 31.
