DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] In order to further understand the content, features and effects of the present invention, the following embodiments are cited and described in detail in conjunction with the accompanying drawings.

[0028] The structure of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Embodiment 1

[0030] As Figures 1 to 4 shown, a wastewater treatment device for vegetable oil by - product processing provided by an embodiment of the present invention includes a wastewater treatment tank 100. A cover plate 110 is fixedly installed at the upper end of the wastewater treatment tank 100. A microbial agent auxiliary diffusion mechanism 300, a liquid inlet 400, and a feeding port 500 are arranged on the cover plate 110. The feeding port 500 is communicated with the wastewater treatment tank 100 and is used to inject microbial agents into the wastewater treatment tank 100. A liquid outlet 600 is arranged at the bottom of the wastewater treatment tank 100. A flexible hose 510 is fixedly connected to the bottom of the feeding port 500. A microbial agent pre - diffusion mechanism 200 is connected to the microbial agent auxiliary diffusion mechanism 300. The microbial agent auxiliary diffusion mechanism 300 is used to uniformly disperse the microbial agents in the wastewater treatment tank 100.

[0031] In this application, the liquid inlet 400 is used to introduce the wastewater from vegetable oil by - product processing, the feeding port 500 is used to add treatment agents, the liquid outlet 600 is used to discharge the treated wastewater, and the microbial agent auxiliary diffusion mechanism 300 is used to fully stir the agents and wastewater to accelerate the reaction rate.

[0032] The microbial agent auxiliary diffusion mechanism 300 includes a motor 310. The output end of the motor 310 is fixedly connected to a speed reducer 320. The motor 310 and the speed reducer 320 are fixedly installed in the middle of the upper end of the cover plate 110. The output end of the speed reducer 320 is fixedly connected to a rotating shaft 330. The rotating shaft 330 is rotatably installed in the wastewater treatment tank 100. A number of stirring blades 340 are equidistantly arranged on the rotating shaft 330.

[0033] Specifically, after the motor 310 is started, its output end drives the speed reducer 320. The speed reducer 320 adjusts the speed of the motor 310 and outputs an appropriate speed. The power is transmitted to the inside of the wastewater treatment tank 100 through the rotating shaft 330 connected to the output end. The stirring blades 340 on the rotating shaft 330 rotate with the rotating shaft 330, stirring and mixing the wastewater and agents in the wastewater treatment tank 100, accelerating the progress of the chemical reaction, and improving the wastewater treatment efficiency and treatment quality.

[0034] The microbial inoculant pre-diffusion mechanism 200 includes a material receiving cylinder 220. On both sides of the material receiving cylinder 220, a connecting rod 221 and a mounting rod 222 are respectively and fixedly connected. One end of the connecting rod 221 away from the material receiving cylinder 220 is rotatably connected to a mounting ring 210. The mounting ring 210 is sleeved on a rotating shaft 330. The upper end of the material receiving cylinder 220 is fixedly connected to a material guiding hopper 223. The material guiding hopper 223 covers the outside of a hose 510. The lower end of the material receiving cylinder 220 is rotatably connected to a mounting frame 250. A number of spiral plates 251 are equidistantly arranged on the mounting frame 250. One end of the mounting rod 222 away from the material receiving cylinder 220 is fixedly installed with a gear 240. Inside the wastewater treatment tank 100, a first toothed plate 231 and a second toothed plate 232 which are meshed with the gear 240 are fixedly installed through a fixing frame 230.

[0035] In this application, the material receiving cylinder 220 is connected to the mounting ring 210 through the connecting rod 221. The mounting ring 210 is fixedly installed on the rotating shaft 330 and can rotate with the rotating shaft 330. When it is necessary to add the medicament, the material receiving cylinder 220 rotates with the rotating shaft 330 to the position of the hose 510. The material guiding hopper 223 covers the hose 510, so that the added medicament can smoothly fall into the material receiving cylinder 220. After the feeding is completed, the material receiving cylinder 220 rotates with the rotating shaft 330. According to the rotating direction of the rotating shaft 330, the gear 240 is correspondingly meshed with the first toothed plate 231 or the second toothed plate 232, so that the material receiving cylinder 220 rotates to a horizontal state (such as 90° or 450°). The material receiving cylinder 220 is immersed in the wastewater. As the material receiving cylinder 220 rotates, the medicament accumulated inside it is evenly dispersed into the wastewater. During this process, the spiral plates 251 rotate, stirring the surrounding wastewater and medicament and accelerating the mixing of the two.

[0036] Preferably, the dimension from the mounting rod 222 to the bottom of the mounting frame 250 is greater than the dimension from the mounting rod 222 to the bottom of the hose 510. Through this setting, when rotating, the mounting frame 250 can stir the bottom of the hose 510, so that the microbial inoculant adhered or blocked inside the hose 510 can be stirred into the wastewater.

[0037] It should be noted that the mounting ring 210 is fixedly sleeved on the rotating shaft 330. This solution is used for the case of low-speed rotation. When the rotating shaft 330 rotates, the material receiving cylinder 220 can also assist in stirring the wastewater. And every time it passes through the first toothed plate 231 and the second toothed plate 232, the gear 240 will stir the material receiving cylinder 220 to rotate. On the one hand, it can prevent the medicament from accumulating at the bottom of 250. On the other hand, it can make 250 stir the bottom of 510, so that the microbial inoculant adhered or blocked inside the hose 510 can be stirred into the wastewater.

[0038] The setting of the microbial inoculant pre-diffusion mechanism 200 effectively avoids the problem of the medicament dispersing everywhere and sticking to the inner wall of the wastewater treatment tank 100 during the medicament addition process, reduces the waste of materials, improves the utilization rate of the medicament, and the setting of the spiral plate 251 further enhances the mixing effect of the medicament and the wastewater, making the treatment process more efficient.

[0039] During specific implementation, the wastewater treatment tank 100 is made of corrosion-resistant stainless steel material, such as 316L stainless steel, which can resist the corrosion of wastewater and medicament and ensure the service life of the tank body. It is also possible to consider using fiberglass material, which has good corrosion resistance, high strength and insulation, and is relatively light in weight. The cover plate 110 is made of the same material as the wastewater treatment tank 100, and stainless steel or fiberglass can be selected. If better sealing performance and a certain degree of flexibility are considered, a rubber sealing gasket can be added at the contact part between the cover plate and the tank body.

[0040] The motor 310 can be selected from the YE2 series of high-efficiency energy-saving motors, and an appropriate power is selected according to the size of the wastewater treatment tank and the stirring requirements, such as 0.75kW, 1.5kW, etc. The reducer 320 can adopt the RV series of worm and worm gear reducers, which have the characteristics of compact structure, large transmission ratio, stable operation, etc., and can convert the high-speed rotation of the motor into a low-speed rotation suitable for stirring. The material of the rotating shaft 330 can be selected as 45# steel, and its strength and toughness are improved through quenching and tempering treatment, and then chrome plating treatment is carried out on the surface to enhance corrosion resistance. The stirring blade 340 can be selected as stainless steel, such as 304 stainless steel, which has good corrosion resistance and strength. The shape of the blade can be a propeller type, a turbine type or an anchor type, etc. The material of the mounting ring 210 can be selected as 45# steel chrome plated, which ensures its wear resistance and corrosion resistance, and the inner diameter matches the rotating shaft 330. The receiving cylinder 220 can be selected as stainless steel, such as 304 stainless steel. Its shape can be cylindrical, and the size is determined according to the capacity of the medicament to be added.

[0041] The materials of the connecting rod 221 and the mounting rod 222 can be selected as 45# steel chrome plated to ensure strength and corrosion resistance. The diameter is determined according to the actual force condition, generally about 10 - 20mm. The material of the guiding hopper 223 can be selected as stainless steel, such as 304 stainless steel. The shape is a funnel shape, the upper mouth diameter is larger than the outer diameter of the hose 510, and the lower mouth diameter is the same as the upper mouth diameter of the receiving cylinder 220. The material of the mounting frame 250 can be selected as stainless steel, such as 304 stainless steel. The shape is a frame structure, and the size is determined according to the size of the receiving cylinder 220 and the installation position. The material of the spiral plate 251 can be selected as stainless steel, such as 304 stainless steel. The spiral angle and size are determined according to the size of the mounting frame 250 and the stirring requirements, generally the spiral angle is between 45° - 60°. The material of the gear 240 can be selected as 45# steel, and the tooth surface hardness is increased through quenching treatment to enhance wear resistance. The module and the number of teeth are determined according to the meshing requirements with the first tooth plate 231 and the second tooth plate 232.

[0042] The hose 510 can be a silicone rubber hose, which has good corrosion resistance, high temperature resistance and flexibility, can resist the erosion of microbial agents and wastewater, and is not easily blocked. The inner diameter is determined according to the size of the feeding port 500 and the chemical agent flow rate, generally about 10-20 mm. The first tooth plate 231 and the second tooth plate 232: The material can be selected as 45# steel and surface hardened. The tooth shape and size match the gear 240, and the length is determined according to the installation space inside the wastewater treatment tank 100. Preferably, both the first tooth plate 231 and the second tooth plate 232 are semi-circular tooth plates and are connected into a circular tooth ring, which can make the gear 240 always drive the material receiving cylinder 220 to rotate.

[0043] Embodiment 2

[0044] Different from Embodiment 1, the mounting ring 210 is not fixedly sleeved on the rotating shaft 330 and can be used in the case of high-speed rotation, as follows:

[0045] Refer to Figures 1 - 6 , the mounting ring 210 is rotatably sleeved on the rotating shaft 330 (for example, connected by a bearing), and further includes a first stop block 700 and a second stop block 710. When the gear 240 rotates 450°, the gear 240 abuts against the second stop block 710. When the material receiving cylinder 220 is located at the lower end of the hose 510, the gear 240 abuts against the first stop block 700. Through this setting, when the rotating shaft 330 rotates the mixed wastewater, the wastewater can be rotated, thereby driving the material receiving cylinder 220, the connecting rod 221 and the mounting rod 222 to rotate until the gear 240 rotates 450° and the gear 240 abuts against the second stop block 710. At this time, the material guiding hopper 223 is in a horizontal state, and the rotating wastewater enters the material receiving cylinder 220 through the material guiding hopper 223 and then is discharged through the spiral plate 251, while evenly diffusing the microbial agent inside the material receiving cylinder 220 into the wastewater.

[0046] Furthermore, a telescopic member 730 is fixedly connected inside the wastewater treatment tank 100, and the telescopic end of the telescopic member 730 is fixedly connected to the first stop block 700 and the second stop block 710. Through this setting, the positions of the first stop block 700 and the second stop block 710 can be adjusted by the telescopic member 730 so that the first stop block 700 and the second stop block 710 do not block the gear 240. Specifically, the telescopic member 730 can be set as a waterproof electric push rod or a manual push-pull rod penetrating the side wall of the wastewater treatment tank 100.

[0047] In specific implementation, the first stop block 700 and the second stop block 710 can be made of stainless steel or high-strength plastic materials, such as polyoxymethylene (POM), which have good wear resistance and rigidity. Telescopic member 730: For a waterproof electric push rod, the outer shell is generally made of stainless steel or aluminum alloy, and the internal motor and transmission components are designed to be sealed to prevent water ingress. For a manual push-pull rod, stainless steel or carbon steel with an anti-corrosion treatment on the surface can be used. It can also be made of the same material as the first stop block 700 and the second stop block 710.

[0048] Working principle of the present invention:

[0049] When treating the wastewater from vegetable oil by-product processing, the wastewater enters the wastewater treatment tank 100 through the liquid inlet 400, and the treatment agent falls into the receiving cylinder 220 of the microbial inoculant pre-diffusion mechanism 200 through the feeding port 500 via the hose 510. The motor 310 drives the reducer 320, the rotating shaft 330 and the stirring blades 340 to stir the wastewater and the treatment agent. The receiving cylinder 220 rotates with the rotating shaft 330 and rotates to the horizontal position under the cooperation of the gear 240 and the toothed plate. As the rotating shaft 330 rotates, the treatment agent in the receiving cylinder 220 is evenly dispersed into the wastewater, and the spiral plate 251 also rotates, further accelerating the mixing of the treatment agent and the wastewater, enabling the wastewater and the treatment agent to fully react. Finally, the treated wastewater is discharged through the liquid outlet 600, realizing the effective treatment of the wastewater from vegetable oil by-product processing.

[0050] In summary: For this wastewater treatment equipment for vegetable oil by-products, by setting the receiving cylinder 220 to receive the added treatment agent, it is avoided that the treatment agent is scattered everywhere after entering the wastewater treatment tank 100 from the feeding port 500 and adheres to the inner wall of the wastewater treatment tank 100, resulting in waste. The receiving cylinder 220 rotates to the horizontal position with the rotating shaft 330, and the treatment agent inside it is evenly dispersed into the wastewater during the rotation, improving the utilization rate of the treatment agent and avoiding waste. The spiral plate 251 further enhances the mixing effect of the treatment agent and the wastewater, improving the wastewater treatment efficiency and treatment quality.
