Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a device for treating organic matter in folic acid production wastewater. Background Art

[0002] Folic acid is known as vitamin B9, anti-anemia factor, etc. Pure folic acid is a dark yellow or orange crystal, odorless and tasteless. Folic acid is one of the indispensable nutrients for the human body. Pregnant women, nursing mothers, infants and young children have a stronger need for folic acid supplementation. Folic acid is found in some green leafy vegetables, fresh fruits and beans. At present, folic acid is produced industrially by synthetic methods.

[0003] Wastewater is produced during the folic acid production process. The composition of the wastewater is complex. It is chemical wastewater with high organic concentration, high salinity and many difficult-to-degrade substances. If it is discharged directly without treatment, it will have a huge impact on the environment. Summary of the invention

[0004] The object of the present invention is to provide a device for treating organic matter in folic acid production wastewater to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: a folic acid production wastewater organic matter treatment device, including a tank body, a liquid inlet pipe and a pressure relief pipe are arranged above the tank body, a liquid outlet pipe is arranged directly below the tank body, a valve is arranged at the output end of the liquid outlet pipe, a pressure relief valve is installed on the pressure relief pipe, a gear box is installed above the tank body, a driving motor is arranged at the input end of the gear box, a rotating shaft is rotatably installed inside the tank body, the rotating shaft is connected to the gear box, a spiral plate is installed on the rotating shaft, and the strain is placed on the spiral plate. The strain is placed on the spiral plate, and the wastewater is infused into the tank body through the liquid inlet pipe. The strain treats the organic matter in the wastewater so that the wastewater meets the discharge requirements. During the decomposition of the organic matter by the strain, the gear box drives the spiral plate to rotate slowly through the rotating shaft, so that the strain is transferred on the same plane, which is convenient for the strain to treat wastewater in different areas, and further improves the treatment efficiency of organic matter in the wastewater.

[0006] The rotating shaft includes a hollow main shaft and an inner shaft installed inside the main shaft. The main shaft and the inner shaft are both connected to a gear box. The upper and lower ends of the main shaft are provided with circulation ports, and the circulation ports are immersed in wastewater. The inner shaft is provided with a plurality of circulation fans, and the main shaft is connected to a spiral plate. The gear box drives the main shaft and the inner shaft to rotate respectively. When the inner shaft is driven to rotate, the inner shaft drives the circulation fan to rotate, and the circulation fan drives the wastewater to flow in the main shaft. Under the action of thrust, the wastewater flows out of and into the main shaft through the circulation port, and then the wastewater circulates in the tank body. The wastewater flows in the tank body by rotating the circulation fan, and the wastewater at different positions can flow through the spiral plate, thereby improving the treatment efficiency of the strain on the wastewater in the tank body.

[0007] The inner shaft is a hollow tube structure with one end closed, a plurality of air holes are arranged on the inner shaft, a rotating joint is connected to the unclosed end of the inner shaft, and the rotating joint is connected to the air supply system. When air needs to be injected into the wastewater, the air supply system injects air into the inner shaft through the rotating joint, so that the air enters the wastewater through the inner shaft.

[0008] The spiral plate is composed of two types of spiral plates with I-shaped and C-shaped cross-sections. The I-shaped spiral plate and the C-shaped spiral plate are detachably connected. Both the I-shaped spiral plate and the C-shaped spiral plate are provided with a number of through holes and through grooves, and the bacterial species are placed on the inner side of the C-shaped spiral plate; the C-shaped spiral plate is connected to the main shaft.

[0009] A heating wire is embedded inside the "C"-shaped spiral plate. Both ends of the heating wire pass through the main shaft and are connected to the power supply board inside the gear box. A temperature sensor is installed inside the tank. The positive and negative electrodes on the power supply board are connected to both ends of the heating wire. The temperature sensor detects the temperature of the wastewater and transmits the temperature data to the control system. According to the temperature requirements of the strain to treat organic matter in the wastewater, the control system connects the power supply board to the circuit or disconnects it from the circuit. The heating wire obtains electrical energy from the power supply board and generates heat. With the rotation of the spiral plate or the circulation of the wastewater, the wastewater is heated.

[0010] The lower end of the liquid inlet pipe is square, and a slot is provided on the side of the lower end of the liquid inlet pipe close to the main shaft, a support plate is installed in the middle of the slot, and a sealing plate is rotatably installed on one side of the support plate inside the slot. A bottom plate is rotatably installed on the lower end of the liquid inlet pipe, and a limit plate and a counterweight block are provided on the side of the bottom plate close to the main shaft. The limit plate is located above the bottom plate, and a "C"-shaped diversion net is installed above the other side of the bottom plate. The connection point between the bottom plate and the liquid inlet pipe is close to the main shaft. Under the counterweight of the counterweight block, the bottom plate is in a horizontal state below the liquid inlet pipe. When wastewater flows in from the liquid inlet pipe, the wastewater impacts the bottom plate, causing the bottom plate to deflect at the lower end of the liquid inlet pipe, directing the wastewater to the diversion net. The bottom plate drives the sealing plate to rotate during the rotation process. After the bottom plate rotates a certain angle, the limit plate rests on the support plate. Through the cooperation of the limit plate and the support plate, the rotation angle of the bottom plate is fixed. The wastewater flows to the diversion net under the guidance of the bottom plate. The wastewater is diverted by the mesh on the diversion net, and the diverted wastewater impacts the inner wall of the tank body. The impact force of the wastewater on the inside of the tank body is reduced by diversion, and the wastewater is directed to the inner wall of the tank body through the bottom plate to prevent the wastewater from impacting the spiral plate.

[0011] The gearbox is installed above the tank body through a support, and one end of the main shaft and the inner shaft are both extended into the gearbox. The main shaft is installed with a main bevel gear, and the inner shaft is installed with a secondary bevel gear. A bracket is installed inside the gearbox, and a slider is installed inside the bracket through a flat key and a keyway. A switching cylinder for driving the slider to move is installed above the bracket. The slider is installed with a transmission shaft through a bearing, and the two ends of the transmission shaft are respectively installed with an output bevel gear and a driven wheel. The output bevel gear drives the main bevel gear or the secondary bevel gear to rotate. Two carrier plates are symmetrically installed inside the gearbox, and each of the carrier plates is installed with a tension cylinder. The output end of the tension cylinder is installed with a shaft seat, and the two shaft seats are mutually matched with the tension shaft. Two supporting plates are slidably installed on the tension shaft, and the supporting plate is installed on the inner wall of the gearbox. A tension wheel is installed on the tension shaft, and a driving wheel is installed on the output end of the drive motor. The driving wheel, the driven wheel and the tension wheel are meshed and connected by a toothed chain. A sliding groove for the sliding of the tension shaft is opened on the supporting plate, and the supporting plate supports the tension shaft. When the switching cylinder lifts or pushes the slider up or down, the tension cylinder pushes the tension shaft toward the inner wall of the gear box or pulls it away from the inner wall of the gear box. The tension shaft adjusts the position of the tension wheel to adjust the tension of the toothed chain. When the output bevel gear meshes with the main bevel gear, the main shaft rotates under the drive of the main bevel gear and drives the spiral plate to move the position of the bacteria in the wastewater; when the output bevel gear rises under the drive of the slider and the transmission shaft, the output bevel gear meshes with the secondary bevel gear, and the inner shaft rotates under the drive of the secondary bevel gear and drives multiple circulation fans to rotate, so that the wastewater circulates inside the tank and the main shaft.

[0012] The main shaft is supported by insulating material, and two concentric electrode grooves with different radii are arranged on the upper end of the main shaft. The two ends of the heating wire are electrically connected to the two electrode grooves respectively. Two electrode rings matching the electrode grooves are arranged under the power supply board, and the electrode rings are rotatably installed in the electrode grooves.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Place the bacteria on the spiral plate and inject the wastewater into the tank through the liquid inlet pipe. The bacteria will treat the organic matter in the wastewater to meet the discharge requirements. During the decomposition of organic matter by the bacteria, the gear box drives the spiral plate to rotate slowly through the shaft, so that the bacteria can be transferred on the same plane, which is convenient for the bacteria to treat wastewater in different areas and further improve the treatment efficiency of organic matter in wastewater.

[0014] 2. The inner shaft drives the circulation fan to rotate, and the circulation fan drives the wastewater to flow in the main shaft. Under the action of thrust, the wastewater flows out through the circulation port and flows into the main shaft, and then the wastewater circulates in the tank. The circulation fan rotates to make the wastewater flow in the tank, so that wastewater at different positions can flow through the spiral plate, improving the treatment efficiency of the bacteria on the wastewater in the tank.

[0022] The spiral plate 5 is composed of two types of spiral plates with I-shaped and C-shaped cross-sections. The I-shaped spiral plate and the C-shaped spiral plate are detachably connected. Both the I-shaped spiral plate and the C-shaped spiral plate are provided with a number of through holes and through grooves 15, and the bacterial species are placed on the inner side of the C-shaped spiral plate; the C-shaped spiral plate is connected to the main shaft 4.

[0023] The gear box 3 drives the main shaft 4 and the inner shaft 6 to rotate respectively. When the inner shaft 6 is driven to rotate, the inner shaft 6 drives the circulation fan 7 to rotate. The circulation fan 7 drives the wastewater to flow in the main shaft 4. Under the action of thrust, the wastewater flows out and flows into the main shaft 4 through the circulation port 16, and then the wastewater circulates in the tank body 1. The wastewater flows in the tank body 1 through the rotation of the circulation fan 7, so that the wastewater at different positions can flow through the spiral plate 5, thereby improving the treatment efficiency of the bacteria on the wastewater in the tank body 1.

[0024] The main shaft 4 is supported by an insulating material. Two concentric electrode grooves 29 with different radii are arranged on the upper end of the main shaft 4. A heating wire is embedded inside the "C"-shaped spiral plate. Both ends of the heating wire pass through the main shaft 4. Both ends of the heating wire are electrically connected to the two electrode grooves 29 respectively. Two electrode rings matching the electrode grooves 29 are arranged under the power supply board 30. The electrode rings are rotatably installed in the electrode grooves 29. A temperature sensor (not shown in the figure) is arranged inside the tank body 1.

[0025] The gear box 3 is installed above the tank body 1 through a support, and one end of the main shaft 4 and the inner shaft 6 are both extended into the gear box 3. The main shaft 4 is installed with a main bevel gear 17, and the inner shaft 6 is installed with a secondary bevel gear 18.

A switching cylinder 20 for driving the slider 26 to move is installed above the bracket 19; The slider 26 is installed with a transmission shaft through a bearing, and an output bevel gear 27 and a driven wheel 23 are installed at both ends of the transmission shaft respectively.

[0027] The working principle of the present invention is as follows: when wastewater flows into the liquid inlet pipe 2, the wastewater impacts the bottom plate 12, causing the bottom plate 12 to deflect at the lower end of the liquid inlet pipe 2, directing the wastewater to the diversion net 14. The bottom plate 12 drives the sealing plate 10 to rotate during the rotation process. After the bottom plate 12 rotates a certain angle, the limit plate 11 abuts against the support plate 9. Through the mutual cooperation of the limit plate 11 and the support plate 9, the rotation angle of the bottom plate 12 is fixed. The wastewater flows to the diversion net 14 under the guidance of the bottom plate 12. The wastewater is diverted by the mesh on the diversion net 14, and the diverted wastewater impacts the inner wall of the tank body 1. When the wastewater stops entering, under the counterweight of the counterweight block 13, the bottom plate 12 is in a horizontal state below the liquid inlet pipe 2, and the sealing plate 10 and the limit plate 11 are reset. The bottom plate 12 blocks the bottom opening of the liquid inlet pipe 2.

[0028] When air needs to be injected into the wastewater, the air supply system injects air into the inner shaft 6 through the rotating joint, so that the air enters the wastewater through the inner shaft 6.

[0029] The positive and negative electrodes on the power supply board 30 are connected to the two ends of the heating wire. The temperature sensor detects the temperature of the wastewater and transmits the temperature data to the control system. According to the temperature requirements of the bacterial strain to treat organic matter in the wastewater, the control system connects the power supply board 30 to the circuit or disconnects it from the circuit. The heating wire obtains electrical energy from the power supply board 30 and generates heat. With the rotation of the spiral plate 5 or the circulation of the wastewater, the wastewater is heated.

[0030] The bacteria in the spiral plate 5 process the organic matter in the wastewater. When the output bevel gear 27 is meshed with the main bevel gear 17, the main shaft 4 rotates under the drive of the main bevel gear 17, and drives the spiral plate 5 to rotate, so as to move the position of the bacteria in the wastewater. When it is necessary to circulate the wastewater in the tank body 1, the slider 26 of the switching cylinder 20 is lifted up, and the output bevel gear 27 rises driven by the slider 26 and the transmission shaft. The output bevel gear 27 meshes with the secondary bevel gear 18 for transmission, and the inner shaft 6 rotates driven by the secondary bevel gear 18, and drives multiple circulation fans 7 to rotate, so that the wastewater circulates inside the tank body 1 and the main shaft 4.

[0031] After the wastewater in the tank body 1 is treated, the valve below the liquid outlet pipe is opened to discharge the treated wastewater out of the tank body 1 .
