An integrated wastewater treatment equipment

Abstract

This utility model relates to the field of wastewater treatment technology, and discloses an integrated wastewater treatment device, including a treatment tank. An inlet pipe is located on the right side of the treatment tank, and a discharge pipe is located on the left side. The treatment tank contains a stirring chamber and a sedimentation chamber. A metal filter screen is fixedly connected inside the treatment tank to filter larger particles. A scraping mechanism is also installed inside the treatment tank. The lateral movement of a collecting plate efficiently scrapes away floating scum and guides it to a feeding mechanism. Slight shaking of the collecting plate breaks the surface tension of the liquid, making it easier for the scum to separate from the water surface, thus improving the scraping effect. This process not only effectively removes scum from the water surface but also breaks down the water surface barrier, promoting normal oxygen exchange with the water and preventing the formation of an anaerobic environment at the bottom of the sedimentation chamber. This significantly improves the sedimentation effect and stabilizes the operating efficiency of the sedimentation tank.

Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an integrated wastewater treatment device. Background Technology

[0002] Wastewater generated in the laboratory cannot be discharged directly and needs to be treated. This treatment equipment is called wastewater treatment equipment. Laboratory wastewater treatment equipment is a device that cleans the wastewater generated in the laboratory so that the wastewater can meet the discharge standards and is less likely to cause environmental pollution.

[0003] According to Chinese Patent Publication No. CN215667544U, an integrated laboratory wastewater treatment device is disclosed, including a treatment device body. The treatment device body has an internal stirring chamber and a sedimentation chamber. Two baffles are fixedly connected inside the treatment device body. A protective cover is fixedly connected to the top left side of the inner wall of the treatment device body, and a motor is fixedly connected to the bottom of the inner wall of the protective cover. This invention uses a motor to start operation. The motor, through a rotating rod and stirring blades, mixes the wastewater and flocculant evenly. The sedimentation chamber settles the wastewater, and a metal filter screen, quartz sand filter plate, and activated carbon adsorption plate filter the wastewater. This solves the problem that existing wastewater treatment devices typically neutralize and discharge wastewater before treatment, failing to treat solid sediments inside the wastewater and easily causing sewer blockages.

[0004] The aforementioned patent uses a sedimentation chamber to settle impurities in wastewater. However, some fine scum floats on the surface of the water due to buoyancy, which hinders oxygen exchange, creating an anaerobic environment at the bottom of the sedimentation chamber. This causes sludge to float to the surface, reducing the efficiency of the sedimentation tank and consequently affecting the sedimentation effect. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an integrated wastewater treatment device that addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an integrated wastewater treatment device, including a treatment tank, an inlet pipe on the right side of the treatment tank, a discharge pipe on the left side of the treatment tank, a stirring chamber and a sedimentation chamber inside the treatment tank, a metal filter screen fixedly connected inside the treatment tank for filtering larger particles, a scraping mechanism inside the treatment tank, the scraping mechanism including a folding plate fixedly connected to the right side of the metal filter screen, an electric push rod fixedly connected to the left side of the folding plate, the electric push rod movably passing through the metal filter screen and extending to its left side, a vertical plate fixedly connected to the left end of the electric push rod, a sliding groove opened inside the vertical plate, a slider slidably connected inside the sliding groove, a limit spring fixedly connected between the slider and the inner wall of the sliding groove, a collecting plate hinged to the left side of the slider, the collecting plate being obliquely arranged, and a plurality of holes opened inside the collecting plate.

[0008] As a further technical solution of this utility model, the processing box is provided with a feeding mechanism, which includes an inclined trough. The inclined trough is connected to a corrugated trough. The inclined trough is higher on the left and lower on the right.

[0010] As a further technical solution of this utility model, a collection box is fixedly connected to the left side of the processing box. The collection box is set at the bottom of the abutment rod and is used to collect impurities.

[0011] As a further technical solution of this utility model, a fixing plate is fixedly connected to the inner wall of the treatment box, a motor is fixedly connected to the top of the fixing plate, and a stirring rod is fixedly connected to the output end of the motor through a coupling.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. This integrated wastewater treatment equipment can efficiently scrape off floating scum by moving the collection plate laterally and guide the scum to the feeding mechanism. The slight shaking of the collection plate can break the surface tension of the liquid, making it easier for the scum to separate from the water surface and improving the scraping effect. This process not only effectively removes the scum on the water surface, but also breaks the isolation layer on the water surface, promotes the normal exchange of oxygen with the water, and prevents the formation of an anaerobic environment at the bottom of the sedimentation chamber, thereby significantly improving the sedimentation effect and stabilizing the operating efficiency of the sedimentation tank.

[0014] 2. This integrated wastewater treatment equipment, through the combined design of the inclined chute and collection box in the feeding mechanism, achieves effective collection and centralized treatment of impurities. It can promptly transfer scraped impurities from inside the equipment, preventing their accumulation and maintaining the cleanliness and stable operation of the equipment. Simultaneously, the centralized storage of collected impurities prevents them from entering the subsequent drainage system, reducing the risk of secondary pollution and ensuring the overall operational safety and stability of the wastewater treatment equipment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 One embodiment of this utility model is as follows: An integrated wastewater treatment device includes a treatment tank 1, an inlet pipe 2 on the right side of the treatment tank 1, a discharge pipe 3 on the left side of the treatment tank 1, a stirring chamber 4 and a sedimentation chamber 5 inside the treatment tank 1, a metal filter screen 6 fixedly connected inside the treatment tank 1 for filtering larger particles, and a scraping mechanism 7 inside the treatment tank 1. The scraping mechanism 7 includes a folding plate 711, which is fixedly connected to the right side of the metal filter screen 6, and an electric push rod 712 fixedly connected to the left side of the folding plate 711. 12 The movement passes through the metal filter screen 6 and extends to its left side. The left end of the electric push rod 712 is fixedly connected to a vertical plate 713. The vertical plate 713 has a groove inside. A slider 714 is slidably connected inside the groove. A limit spring is fixedly connected between the slider 714 and the inner wall of the groove. A collection plate 715 is hinged to the left side of the slider 714. The collection plate 715 is set at an angle. Several holes are opened inside the collection plate 715. A wave groove 716 is opened on the inner wall of the treatment box 1. A connecting rod 717 is fixedly connected to the back of the collection plate 715. The connecting rod 717 is slidably connected inside the wave groove 716.

[0022] In the above application, laboratory wastewater flows into treatment tank 1 through inlet pipe 2. After entering, the wastewater reaches mixing chamber 4. Motor 10 on fixed plate 9 operates, driving stirring rod 11 via coupling to agitate the wastewater and disinfectant, making them evenly mixed. The mixed wastewater flows into sedimentation chamber 5 and passes through metal filter screen 6 to filter out larger particles. After entering sedimentation chamber 5, sedimentation occurs. Some scum floats on the water surface, which can hinder oxygen exchange and affect the sedimentation effect. At this time, scraping mechanism 7 is activated. Electric push rod 712 on folding plate 711 pushes vertical plate 713 to the left. Sliding groove on vertical plate 713 guides slider 714 to slide. Sliding slider 714 drives connecting rod 717 on the side of collection plate 715 to slide along wave groove 716 via limit spring and hinge structure, which makes collection plate 715 vibrate slightly, which can break the surface tension of the liquid, making it easier for scum to separate from the water surface and improving the scraping effect. Under the action of wave groove 716, collection plate 715 guides scum to feeding mechanism 8.

[0023] Please see Figure 1-4Based on the above embodiments, in another embodiment of this utility model, the processing box 1 is provided with a feeding mechanism 8. The feeding mechanism 8 includes an inclined groove 811, which is connected to a corrugated groove 716. The inclined groove 811 is higher on the left and lower on the right. The inclined groove 811 is provided so that the collecting plate 715 can be lifted. A first spring 812 is fixedly connected to the left side of the vertical plate 713 and is fixedly connected to the collecting plate 715. A connecting plate 813 is fixedly connected to the left side of the processing box 1, and the top of the connecting plate 813 is fixed. A contact rod 814 is connected to the treatment box 1. A collection box 815 is fixedly connected to the left side of the treatment box 1. The collection box 815 is located at the bottom of the contact rod 814 and is used to collect impurities. A fixing plate 9 is fixedly connected to the inner wall of the treatment box 1. A motor 10 is fixedly connected to the top of the fixing plate 9. A stirring rod 11 is fixedly connected to the output end of the motor 10 through a coupling. The stirring rod 11 passes through the fixing plate 9 and is rotatably connected to the bottom inner wall of the treatment box 1. The stirring rod 11 is used to fully stir and mix the wastewater and disinfectant.

[0024] The working principle of this utility model is as follows: the scum is scraped into the inclined groove 811 of the feeding mechanism 8. The inclined groove 811 is higher on the left and lower on the right, which can lift the collecting plate 715. When it is lifted to a certain height, the collecting plate 715 tilts under the action of the abutment rod 814. The scum slides down under the action of gravity and falls into the collecting box 815, realizing the collection of impurities and avoiding secondary pollution. After sedimentation and scum treatment, the wastewater is finally discharged from the treatment tank 1 through the valve by opening the valve of the discharge pipe 3, thus completing the wastewater treatment.

[0025] This utility model provides an integrated wastewater treatment device. There are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
