Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, and in particular relates to a wastewater treatment device for vegetable oil by-product processing. Background Technology

[0002] Vegetable oil by-products are diverse, with common ones including oil cake, oil meal, oil residue, and soapberry. Taking oil cake and oil meal as examples, they are the residues left after vegetable oilseeds have been pressed or leached to extract oil. Vegetable oil processing generates a large amount of wastewater, which often contains a large amount of pollutants such as oil, organic matter, and suspended solids. Direct discharge of this wastewater would cause serious environmental pollution, so wastewater treatment equipment is needed to treat it.

[0003] In the prior art, patent CN110143732B proposes a method for treating wastewater from vegetable oil by-product processing. This method uses a combination of physical, chemical, and biological treatment methods, which are simple, easy to implement, and have good treatment effects.

[0004] Existing technologies require the addition of chemicals to wastewater, such as the microbial agents mentioned in the above scheme. The pollutants in the wastewater are removed through thorough mixing of the two. However, existing wastewater treatment equipment usually adds the chemicals directly into the wastewater treatment tank through the feed port. After leaving the feed port, the chemicals tend to scatter and adhere to the inner wall of the wastewater treatment tank, making it difficult to mix with the wastewater later, resulting in material waste and a decline in quality. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention provides a wastewater treatment device for vegetable oil by-product processing. It has the advantages of high reagent utilization, low waste, and high efficiency and quality in wastewater treatment. It solves the problem that existing wastewater treatment equipment usually adds reagents directly into the wastewater treatment tank through the feed port. After leaving the feed port, the reagents tend to scatter and adhere to the inner wall of the wastewater treatment tank, making it difficult to mix with the wastewater later, resulting in material waste and quality degradation.

[0006] This invention is implemented as follows: a wastewater treatment device for vegetable oil by-product processing includes a wastewater treatment tank. A cover plate is fixedly installed on the upper end of the wastewater treatment tank. The cover plate is provided with a microbial agent auxiliary diffusion mechanism, a liquid inlet, and a feeding port. The feeding port is connected to the wastewater treatment tank and is used to inject microbial agents into the wastewater treatment tank. A liquid outlet is provided at the bottom of the wastewater treatment tank. A flexible tube is fixedly connected to the bottom of the feeding port. A microbial agent pre-diffusion mechanism is connected to the microbial agent auxiliary diffusion mechanism. The microbial agent auxiliary diffusion mechanism is used to uniformly disperse the microbial agents in the wastewater treatment tank.

[0007] As a preferred embodiment of the present invention, the microbial agent-assisted diffusion mechanism includes a motor, the output end of which is fixedly connected to a reducer, the motor and the reducer are fixedly installed on the upper middle part of the cover plate, the output end of the reducer is fixedly connected to a rotating shaft, the rotating shaft is rotatably installed inside the wastewater treatment tank, and a plurality of stirring blades are equidistantly arranged on the rotating shaft.

[0008] As a preferred embodiment of the present invention, the microbial agent pre-diffusion mechanism includes a receiving cylinder, with a connecting rod and an installation rod fixedly connected to both sides of the receiving cylinder, and an installation ring rotatably connected to the end of the connecting rod away from the receiving cylinder, the installation ring being sleeved on the rotating shaft.

[0009] As a preferred embodiment of the present invention, a guide hopper is fixedly connected to the upper end of the receiving cylinder, and the guide hopper is covered at the lower end of the flexible tube.

[0010] As a preferred embodiment of the present invention, the lower end of the receiving cylinder is rotatably connected to a mounting frame, and a plurality of spiral plates are equidistantly arranged on the mounting frame.

[0011] As a preferred embodiment of the present invention, the dimension from the mounting rod to the bottom of the mounting bracket is greater than the dimension from the mounting rod to the bottom of the hose.

[0012] As a preferred embodiment of the present invention, a gear is fixedly installed at the end of the mounting rod away from the receiving cylinder, and a first toothed plate and a second toothed plate that mesh with the gear are fixedly installed inside the wastewater treatment tank via a fixing frame.

[0013] As a preferred embodiment of the present invention, the mounting ring is fixedly sleeved on the rotating shaft.

[0014] In a preferred embodiment of the present invention, the mounting ring is rotatably sleeved on the rotating shaft, and further includes a first stop and a second stop. When the gear rotates 450°, the gear and the second stop collide. When the receiving cylinder is located at the lower end of the hose, the gear and the first stop collide.

[0015] As a preferred embodiment of the present invention, a telescopic component is fixedly connected inside the wastewater treatment tank, and the telescopic end of the telescopic component is fixedly connected to the first stop block and the second stop block.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. This invention uses a receiving cylinder to receive the added chemicals, preventing the chemicals from spreading and adhering to the inner wall of the wastewater treatment tank after entering through the feeding port, thus avoiding waste. The receiving cylinder rotates with the shaft to a horizontal position, and the chemicals inside are evenly dispersed into the wastewater during the rotation, improving the utilization rate of the chemicals and avoiding waste.

[0018] 2. This invention features a spiral plate that is rotated at one end of the receiving cylinder. As the receiving cylinder rotates with the rotating shaft, the spiral plate rotates accordingly, stirring the surrounding wastewater and reagents, accelerating their mixing, further enhancing the mixing effect of the reagents and wastewater, and improving wastewater treatment efficiency and quality.

[0019] 3. When the shaft rotates, the receiving cylinder can also assist in stirring the wastewater. Furthermore, each time it passes the first and second toothed plates, the gears will cause the receiving cylinder to rotate. On the one hand, this prevents the agent from accumulating at the bottom, and on the other hand, the rotation of the bottom can move any microbial agents that are stuck or blocked inside the hose into the wastewater.

Detailed Implementation

[0027] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

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

[0029] Example 1

[0030] like Figures 1 to 4 As shown in the figure, an embodiment of the present invention provides a wastewater treatment device for vegetable oil by-product processing, including a wastewater treatment tank 100. A cover plate 110 is fixedly installed on the upper end of the wastewater treatment tank 100. The cover plate 110 is provided with a microbial agent auxiliary diffusion mechanism 300, a liquid inlet 400, and a feeding port 500. The feeding port 500 is connected to the wastewater treatment tank 100 and is used to inject microbial agents into the wastewater treatment tank 100. A liquid outlet 600 is provided at the bottom of the wastewater treatment tank 100. A 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 inlet 400 is used to introduce wastewater from the processing of vegetable oil by-products, the feed inlet 500 is used to add treatment agents, the 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-assisted diffusion mechanism 300 includes a motor 310, a reducer 320 fixedly connected to the output end of the motor 310, the motor 310 and the reducer 320 fixedly installed in the middle of the upper end of the cover plate 110, a rotating shaft 330 fixedly connected to the output end of the reducer 320, the rotating shaft 330 rotatably installed in the wastewater treatment tank 100, and a number of stirring blades 340 are equidistantly arranged on the rotating shaft 330.

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

[0034] The microbial agent pre-diffusion mechanism 200 includes a receiving cylinder 220. A connecting rod 221 and an installation rod 222 are fixedly connected to both sides of the receiving cylinder 220, respectively. An installation ring 210 is rotatably connected to the end of the connecting rod 221 away from the receiving cylinder 220. The installation ring 210 is sleeved on the rotating shaft 330. A guide hopper 223 is fixedly connected to the upper end of the receiving cylinder 220. The guide hopper 223 is covered outside the hose 510. An installation frame 250 is rotatably connected to the lower end of the receiving cylinder 220. Several spiral plates 251 are equidistantly arranged on the installation frame 250. A gear 240 is fixedly installed at the end of the installation rod 222 away from the receiving cylinder 220. A first toothed plate 231 and a second toothed plate 232 that mesh with the gear 240 are fixedly installed inside the wastewater treatment tank 100 through a fixing frame 230.

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

[0036] Preferably, the dimension from the bottom of the mounting rod 222 to the bottom of the mounting bracket 250 is larger than the dimension from the bottom of the mounting rod 222 to the bottom of the hose 510. With this arrangement, when rotated, the mounting bracket 250 can move the bottom of the hose 510, thereby moving any microbial agents that are stuck or blocked inside the hose 510 into the wastewater.

[0037] It should be noted that the mounting ring 210 is fixedly sleeved on the rotating shaft 330. This design is for low-speed rotation. When the rotating shaft 330 rotates, the receiving cylinder 220 can also assist in stirring the wastewater. Furthermore, each time the gear 240 passes the first toothed plate 231 and the second toothed plate 232, it will cause the receiving cylinder 220 to rotate. On the one hand, this can prevent the agent from accumulating at the bottom of 250, and on the other hand, it can cause 250 to move the bottom of 510, thereby moving the microbial agent that is stuck or blocked inside the hose 510 into the wastewater.

[0038] The microbial agent pre-diffusion mechanism 200 effectively avoids the problem of the agent being scattered and adhering to the inner wall of the wastewater treatment tank 100 during the addition process, reducing material waste and improving the utilization rate of the agent. The spiral plate 251 further enhances the mixing effect between the agent and the wastewater, making the treatment process more efficient.

[0039] In practical implementation, the wastewater treatment tank 100 is made of corrosion-resistant stainless steel, such as 316L stainless steel, which can resist the corrosion of wastewater and chemicals, ensuring the service life of the tank. Fiberglass can also be considered, as it has good corrosion resistance, high strength, and insulation, and is relatively lightweight. The cover plate 110 is made of a material that matches the wastewater treatment tank 100, and can be made of stainless steel or fiberglass. For better sealing performance and a certain degree of flexibility, rubber sealing gaskets can be added to the contact points between the cover plate and the tank body.

[0040] The motor 310 can be a YE2 series high-efficiency energy-saving motor. The appropriate power, such as 0.75kW or 1.5kW, can be selected based on the size of the wastewater treatment tank and the stirring requirements. The reducer 320 can be an RV series worm gear reducer, characterized by its compact structure, large transmission ratio, and smooth operation, converting the high-speed rotation of the motor into a low-speed rotation suitable for stirring. The shaft 330 can be made of 45# steel, heat-treated to improve its strength and toughness, and then chrome-plated to enhance corrosion resistance. The stirring blades 340 can be made of stainless steel, such as 304 stainless steel, which has good corrosion resistance and strength. The blade shape can be propeller-type, turbine-type, or anchor-type. The mounting ring 210 can be made of the same 45# steel as the shaft 330, chrome-plated to ensure its wear resistance and corrosion resistance, and its inner diameter matches that of the shaft 330. The receiving cylinder 220 can be made of stainless steel, such as 304 stainless steel. Its shape can be cylindrical, and its size is determined by the required amount of added reagent.

[0041] The connecting rod 221 and mounting rod 222 can be made of chrome-plated 45# steel to ensure strength and corrosion resistance. Their diameter is determined based on the actual stress, generally around 10-20mm. The guide hopper 223 can be made of stainless steel, such as 304 stainless steel. It is funnel-shaped, with an upper diameter larger than the outer diameter of the hose 510 and a lower diameter the same as the upper diameter of the receiving cylinder 220. The mounting frame 250 can be made of stainless steel, such as 304 stainless steel. It has a frame structure, and its dimensions are determined based on the size of the receiving cylinder 220 and its installation position. The spiral plate 251 can be made of stainless steel, such as 304 stainless steel. The spiral angle and size are determined based on the size of the mounting frame 250 and the mixing requirements, generally between 45° and 60°. The gear 240 can be made of 45# steel, hardened to improve tooth surface hardness and enhance wear resistance. The module and number of teeth are determined based on the meshing requirements with the first toothed plate 231 and the second toothed plate 232.

[0042] The hose 510 can be made of silicone rubber, which has good corrosion resistance, high temperature resistance, and flexibility. It can resist the erosion of microbial agents and wastewater and is not easily clogged. The inner diameter is determined according to the size of the feed port 500 and the agent flow rate, generally around 10-20mm. The first toothed plate 231 and the second toothed plate 232 can be made of 45# steel with surface quenching treatment. 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, the first toothed plate 231 and the second toothed plate 232 are both semi-circular toothed plates and connected as a circular toothed ring, so that the gear 240 can always drive the receiving cylinder 220 to rotate.

[0043] Example 2

[0044] Unlike Embodiment 1, the mounting ring 210 is not fixedly sleeved on the rotating shaft 330, and can be used for high-speed rotation, as detailed below:

[0045] See Figures 1-6 The mounting ring 210 is rotatably sleeved on the rotating shaft 330 (e.g., connected via a bearing), and also includes a first stop 700 and a second stop 710. When the gear 240 rotates 450°, the gear 240 and the second stop 710 abut against each other. When the receiving cylinder 220 is located at the lower end of the hose 510, the gear 240 and the first stop 700 abut against each other. With this arrangement, when the rotating shaft 330 rotates to mix the wastewater, the wastewater can be rotated, thereby pushing the receiving cylinder 220, the connecting rod 221, and the mounting rod 222 to rotate until the gear 240 rotates 450°, at which point the gear 240 and the second stop 710 abut against each other. At this time, the guide hopper 223 is in a horizontal state, and the rotating wastewater enters the receiving cylinder 220 through the guide hopper 223, and then is discharged through the spiral plate 251, while the microbial agent inside the receiving cylinder 220 is evenly diffused into the wastewater.

[0046] Furthermore, a telescopic component 730 is fixedly connected inside the wastewater treatment tank 100, and the telescopic end of the telescopic component 730 is fixedly connected to the first stop 700 and the second stop 710. With this configuration, the positions of the first stop 700 and the second stop 710 can be adjusted via the telescopic component 730, ensuring that the first stop 700 and the second stop 710 do not obstruct the gear 240. Specifically, the telescopic component 730 can be configured as a waterproof electric push rod, or as a manual push-pull rod penetrating the side wall of the wastewater treatment tank 100.

[0047] In practical implementation, the first stop 700 and the second stop 710 can be made of stainless steel or high-strength plastic, such as polyoxymethylene (POM), which has good wear resistance and rigidity. Telescopic component 730: For waterproof electric push rods, the outer shell is generally made of stainless steel or aluminum alloy, and the internal motor and transmission components are sealed to prevent water damage. For manual push-pull rods, stainless steel or carbon steel with an anti-corrosion treatment can be used. Alternatively, the same material as the first stop 700 and the second stop 710 can be used.

[0048] Working principle of the invention:

[0049] When treating wastewater from vegetable oil by-product processing, the wastewater enters the wastewater treatment tank 100 through the inlet 400. The treatment agent falls into the receiving cylinder 220 of the microbial agent pre-diffusion mechanism 200 through the feeding port 500 and 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 agent. The receiving cylinder 220 rotates with the rotating shaft 330 and rotates to a horizontal position with the cooperation of the gear 240 and the toothed plate. As the rotating shaft 330 rotates, the agent in the receiving cylinder 220 is evenly dispersed into the wastewater. The spiral plate 251 also rotates, further accelerating the mixing of the agent and the wastewater, so that the wastewater and the agent can fully react. Finally, the treated wastewater is discharged through the outlet 600, realizing the effective treatment of wastewater from vegetable oil by-product processing.

[0050] In summary, this wastewater treatment equipment for vegetable oil by-product processing utilizes a receiving cylinder 220 to collect added chemicals, preventing them from dispersing and adhering to the inner wall of the wastewater treatment tank 100 after entering through the feeding port 500, thus avoiding waste. The receiving cylinder 220 rotates horizontally with the rotating shaft 330, ensuring the chemicals are evenly dispersed into the wastewater during rotation, improving chemical utilization and preventing waste. The spiral plate 251 further enhances the mixing effect between the chemicals and wastewater, improving wastewater treatment efficiency and quality.
