Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment devices, specifically to a device for oxidative coupled biochemical treatment of industrial wastewater. Background Technology

[0002] The oxidation-coupling biochemical treatment device for industrial wastewater is a device that combines chemical oxidation with biochemical treatment to efficiently degrade recalcitrant organic matter in industrial wastewater.

[0003] A search revealed Chinese patent application CN202321265623.2, which discloses an advanced oxidation-coupled biochemical treatment device for industrial wastewater. The device includes a tank with an opening on one side of the upper part, a chemical inlet at the top, a water inlet on one side of the chemical inlet, a water tank on one side of the upper part, a drain outlet at the bottom, a drain cover at one end of the drain outlet, a drain outlet at the bottom, a filter device inside the opening, two vertically arranged stirring devices inside the tank, blowers on both sides of the lower part of the tank, a sludge pushing device inside the bottom of the tank, cleaning devices on the front and rear sides of the tank, a sampling device in one corner of the tank, and legs at the four corners of the bottom of the tank. This prior art device for advanced oxidation-coupled biochemical treatment of industrial wastewater not only effectively cleans wastewater treatment equipment but also allows for sampling at the bottom of the tank and accelerates the reaction rate between the chemicals and the wastewater.

[0004] In the aforementioned prior art, when sampling wastewater after treatment in a wastewater treatment device, a water pump installed at the top connects to the bottom of the tank via a water pipe, thereby sampling the water at the bottom of the tank. While this sampling method samples water from the bottom of the tank compared to traditional sampling devices, the pipe is fixed to the bottom of the tank. Initially, the pipe opening is easily blocked by a large amount of impurities in the wastewater, making sampling inconvenient or resulting in samples with high impurity content, affecting the test results. Furthermore, since the pipe is fixed to the bottom of the tank, sampling the treated water at the bottom is inconvenient, making it difficult to sample the water in the middle of the tank, leading to inconsistent test results. The results show significant deviations. Furthermore, when scraping away residual sludge at the bottom of the wastewater treatment tank, a motor drives a threaded rod to rotate, which in turn uses the threaded engagement of the rod with the scraper to move the scraper back and forth. This scraping method has several drawbacks. First, the threaded engagement point between the rod and the scraper is prone to obstruction due to the adhesion of impurities. Second, the scraper's ends are not restricted. During scraping, the sludge has a certain weight and resistance. When the resistance at both ends of the scraper is unbalanced, the scraper is prone to tilting, preventing subsequent scrapers from properly engaging with the threaded rod and thus hindering movement, making it highly susceptible to damage.

[0008] As a preferred embodiment of the above technical solution, the control component includes a first electric telescopic rod inserted inside the lower end of the sleeve, one end of the first electric telescopic rod being fixedly connected to the sleeve, and a baffle being fixedly connected to the output shaft of the first electric telescopic rod.

[0009] The above technical solution involves sealing the stainless steel water pipe at the lower end of the sleeve using the first electric telescopic rod and baffle.

[0010] As a preferred embodiment of the above technical solution, the adjustment component includes a fixed plate fixedly connected to the outer side of the upper end of the housing, and a first motor fixedly connected to the lower side of the fixed plate. The output shaft of the first motor passes through the fixed plate and is fixedly connected to a threaded rod. Both ends of the threaded rod are rotatably connected to the fixed plate. A threaded plate is threadedly engaged on the outer side of the threaded rod, and the end of the threaded plate away from the threaded rod is fixedly connected to the water pump.

[0012] As a preferred embodiment of the above technical solution, the scraping assembly includes a second electric telescopic rod fixedly connected to the inner side of the lower end of the stirring rod, and a scraper is fixedly connected to the lower end of the second electric telescopic rod.

[0013] As a preferred embodiment of the above technical solution, the scraper is arc-shaped.

[0014] The above technical solution utilizes the arc-shaped design of the scraper to facilitate the removal of silt from the bottom of the tank.

[0025] like Figure 1 - Figure 6 As shown, this utility model provides a technical solution: a device for oxidation-coupled biochemical treatment of industrial wastewater, including a housing 1, a control box 11 fixedly connected to the outer side of the middle of the housing 1, an inlet 12 fixedly connected to one upper end of the housing 1, an outlet 13 fixedly connected to the middle of the lower side of the housing 1, a telescopic component 2 provided on one side of the upper end of the housing 1, and the telescopic component 2 includes a sleeve 21 provided on the inner side of the upper end of the housing 1, a retaining ring 22 fixedly connected to the upper end of the sleeve 21, and multiple sets of sleeves 21 and retaining rings 22 are interlocked and installed, with the upper sleeve 21 fixedly connected to... The sleeve 21 is attached to the housing 1, and the upper end of the sleeve 21 is equipped with an extraction component 3, the lower end of the sleeve 21 is equipped with a control component 4, the upper end of the extraction component 3 is equipped with an adjustment component 5, the middle end of the housing 1 is equipped with a stirring component 6, and the lower end of the stirring component 6 is equipped with a scraping component 7. By cooperating with the telescopic component 2 and the extraction component 3, when sampling inside the housing 1, sampling can be carried out flexibly according to the usage requirements, reducing the impact of impurities in the sewage accumulation on sampling. At the same time, it can also quickly clean up the residual sludge after treatment, improving the convenience of cleaning.

[0026] like Figure 2 and Figure 3 As shown, the extraction component 3 includes a water pump 31 installed on the upper side of the housing 1, and a stainless steel water pipe 32 is fixedly connected to one end of the water pump 31. A discharge pipe 33 is fixedly connected to the lower side of the water pump 31, and the lower end of the discharge pipe 33 is fixedly connected to the sleeve 21. When the water pump 31 is started, it extracts and samples the wastewater in the housing 1 through the stainless steel water pipe 32. The extracted sample is discharged through the discharge pipe 33.

[0027] like Figure 6 As shown, the control component 4 includes a first electric telescopic rod 41 inserted inside the lower end of the sleeve 21, and one end of the first electric telescopic rod 41 is fixedly connected to the sleeve 21. The output shaft of the first electric telescopic rod 41 is fixedly connected to a baffle 42. When the first electric telescopic rod 41 is activated, it drives the baffle 42 to retract, thereby opening the lower end of the stainless steel water pipe 32.

[0028] like Figure 3 and Figure 4 As shown, the adjustment assembly 5 includes a fixed plate 51 fixedly connected to the outer side of the upper end of the housing 1, and a first motor 52 fixedly connected to the lower side of the fixed plate 51. The output shaft of the first motor 52 passes through the fixed plate 51 and is fixedly connected to a threaded rod 53. The two ends of the threaded rod 53 are rotatably connected to the fixed plate 51. A threaded plate 54 is threadedly engaged on the outer side of the threaded rod 53. The end of the threaded plate 54 away from the threaded rod 53 is fixedly connected to the water pump 31. The first motor 52 is started under the support of the fixed plate 51. After the first motor 52 is started, the output shaft drives the threaded rod 53 to rotate. After the threaded rod 53 rotates, it drives the water pump 31 to move by engaging with the threaded plate 54.

[0029] like Figure 3 As shown, the stirring assembly 6 includes a second motor 61 fixedly connected to the upper side of the middle end of the housing 1, and the output shaft of the second motor 61 passes through the housing 1 and is fixedly connected to a stirring rod 62. The lower end of the stirring rod 62 is inserted into the housing 1. When the second motor 61 is started, its output shaft drives the stirring rod 62 to rotate. After the stirring rod 62 rotates, it drives the scraper 72 to rotate through the second electric telescopic rod 71.

[0030] like Figure 3 As shown, the scraping assembly 7 includes a second electric telescopic rod 71 fixedly connected to the inner side of the lower end of the stirring rod 62, and a scraper 72 fixedly connected to the lower end of the second electric telescopic rod 71. After the second electric telescopic rod 71 is activated to extend, it pushes the scraper 72 to move downward. After the scraper 72 moves downward to fit against the bottom of the box 1, the second electric telescopic rod 71 is closed. Then, the second motor 61 is activated to drive the stirring rod 62 and the scraper 72 to rotate, thereby using the scraper 72 to scrape and discharge the sludge at the bottom of the box 1.

[0031] like Figure 4 As shown, scraper 72 is arc-shaped.

[0032] Working principle: When sampling the treated wastewater inside tank 1, the first motor 52 can be started with the support of the fixed plate 51. After the first motor 52 starts, the output shaft drives the threaded rod 53 to rotate. After the threaded rod 53 rotates, it engages with the threaded plate 54, causing the threaded plate 54 to drive the water pump 31 to move. After the water pump 31 moves, it pushes the sleeve 21 through the stainless steel water pipe 32 to extend and unfold with the assistance of the retaining ring 22. When the stainless steel water pipe 32 pushes the sleeve 21 to extend to the appropriate position, the first motor 52 is turned off. Then, the first electric telescopic rod 41 is started to drive the baffle 42 to retract, thereby opening the lower end of the stainless steel water pipe 32. Subsequently, the water pump 31 is started to extract and sample the wastewater inside tank 1 through the stainless steel water pipe 32. The collected samples are discharged through the discharge pipe 33. In the early stage, when the wastewater and chemical agents in the tank 1 are mixed, the second motor 61 can be started to drive the stirring rod 62 to rotate through its output shaft. After the stirring rod 62 rotates, it drives the scraper 72 to rotate through the second electric telescopic rod 71. Thus, the wastewater and chemical agents are stirred and mixed by the rotation of the stirring rod 62 and the scraper 72. When it is necessary to clean the sludge remaining at the bottom of the tank 1, the second electric telescopic rod 71 is started to extend and push the scraper 72 down. After the scraper 72 moves down to fit against the bottom of the tank 1, the second electric telescopic rod 71 is closed. Then, the second motor 61 is started to drive the stirring rod 62 and the scraper 72 to rotate, thus scraping and discharging the sludge at the bottom of the tank 1 by the scraper 72.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
