Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically a wastewater secondary pressurization and conveying device for water treatment. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. In wastewater treatment, wastewater needs to be discharged into a sedimentation tank to settle large particulate impurities. Small particulate impurities in the wastewater are then decomposed through biodegradation or chemical materials, thereby achieving wastewater purification.

[0003] When treating large particles of wastewater by sedimentation in a sedimentation tank, the wastewater needs to be discharged sequentially into multiple sedimentation tanks. This requires pressurizing and rapidly conveying the wastewater through a pressurized conveying device as it flows into different sedimentation tanks. This prevents the large amount of impurities in the wastewater from clogging the pipes. Furthermore, once the impurities in the wastewater settle into the sedimentation tank, they accumulate at the bottom, making it difficult to remove them. Excessive accumulation of impurities can also affect the efficiency of the sedimentation tank in filtering wastewater impurities.

[0004] Therefore, a secondary pressurized conveying device for wastewater treatment is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and address the problems of existing equipment, this utility model proposes a secondary pressurized conveying device for wastewater treatment.

[0006] The technical solution adopted by this utility model to solve its technical problem is a secondary pressurized conveying device for wastewater treatment, including a primary sedimentation tank. An inlet pipe is installed on the top left side of the primary sedimentation tank. Multiple grid filter plates are installed inside the primary sedimentation tank. An outlet pipe is installed on the right side of the primary sedimentation tank. A first pressurized water pump is installed on the right side of the outlet pipe. A sedimentation tank is installed on the back of the first pressurized water pump. A conveying assembly is installed inside the sedimentation tank.

[0007] Furthermore, multiple grid filter plates are arranged in an array from left to right, and the filter holes of the multiple grid filter plates decrease in size, which can block and settle the impurities contained in the wastewater.

[0008] The conveying assembly includes a vent hole at the top of the settling tank, a conveying cylinder fixedly installed inside the vent hole, an mounting plate fixedly installed at the top of the conveying cylinder, a discharge port at the top of the outer surface of the conveying cylinder, a drive motor mounted at the top of the mounting plate, a rotating shaft mounted through the bottom of the output shaft of the drive motor, and a spiral blade fixedly installed on the outer surface of the rotating shaft.

[0009] Preferably, the bottom of the conveying cylinder is located at the bottom of the inner wall of the settling tank, and the rotating shaft is installed inside the conveying cylinder.

[0010] Preferably, the bottom of the sedimentation tank is provided with a drain outlet, a collar is fixedly installed at the bottom of the drain outlet, and a filter plate is installed on the bottom of the inner wall of the collar.

[0011] Preferably, a rotating rod is installed on the top of the filter plate, a connecting rod is fixedly installed on the top of the rotating rod, a connecting sleeve is installed on the top of the connecting rod, and the connecting sleeve is installed at the bottom of the rotating shaft.

[0012] Preferably, a water supply pipe is installed at the bottom of the drain outlet, a second booster pump is installed at the outlet end of the water supply pipe, and a second water supply pipe is installed at the top of the second booster pump.

[0013] Furthermore, the second pressurized water pump can pressurize and quickly transport the sewage discharged from the sedimentation tank to the biodegradation tank or chemical decomposition tank, preventing the sewage from flowing slowly and clogging the pipes.

[0014] Preferably, a control box is installed on the top of the sedimentation tank, and the control box is used to control the start and stop of the drive motor, the first pressurized water pump and the second pressurized water pump.

[0015] The beneficial effects of this utility model are:

[0016] This invention uses a first pressurized water pump to rapidly transport pre-filtered wastewater into the sedimentation tank. The wastewater flows out from the collar at the bottom of the drain outlet. The filter plate inside the collar filters impurities from the wastewater, causing them to accumulate at the bottom of the sedimentation tank's inner wall. Then, the rotating spiral blades transport the impurities within the conveying cylinder, allowing them to be discharged from the outlet. This achieves the effect of further sedimentation and filtration of impurities in the wastewater and the discharge of the precipitated impurities from the sedimentation tank.

[0017] 2. In this utility model, when sewage flows out through the filter plate, impurities will accumulate on the top of the filter plate and block it. The connecting sleeve can be fitted and fixed to the bottom of the rotating shaft. The rotation of the rotating shaft will drive the connecting sleeve, connecting rod and rotating rod to rotate together. In turn, the rotating rod will push away the impurities accumulated on the top of the filter plate to prevent the impurities from blocking the filter plate. This achieves the effect of sewage being discharged from the sedimentation tank and then pressurized and transported by the second pressurizing water pump, and the impurities in the sewage being settled and filtered out.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 As shown, a secondary pressurized conveying device for wastewater treatment includes a primary sedimentation tank 1. An inlet pipe 11 is installed on the top left side of the primary sedimentation tank 1. Multiple grid filter plates 12 are installed inside the primary sedimentation tank 1. An outlet pipe 2 is installed on the right side of the primary sedimentation tank 1. A first pressurized water pump 21 is installed on the right side of the outlet pipe 2. A sedimentation tank 3 is installed on the back of the first pressurized water pump 21. A conveying assembly 31 is installed inside the sedimentation tank 3.

[0028] Furthermore, wastewater is discharged into the primary sedimentation tank 1 through the inlet pipe 11, allowing impurities in the wastewater to be filtered through a grid filter plate 12 with multiple filter plates of decreasing size. The filtered impurities settle to the bottom of the primary sedimentation tank 1, achieving preliminary filtration of large particles in the wastewater. However, the wastewater still contains a large amount of impurities after passing through the grid filter plate 12 in the primary sedimentation tank 1. When the wastewater flows out through the outlet pipe 2, the internal impurities cause the wastewater flow rate to be slow. The outlet pipe 2 is connected to the first pressurized water pump 21, which is powered on to pressurize and transport the wastewater, increasing the wastewater flow rate and preventing the wastewater from clogging the outlet pipe 2. The first pressurized water pump 21 can then be connected to a pipe at the outlet to input the wastewater into the sedimentation tank 3 for further filtration of impurities, achieving the effect of the first pressurized transport and filtration of the wastewater.

[0029] First, considering the issue of how to filter impurities from wastewater within sedimentation tank 3, the following is presented: Figure 2 and Figure 3 The specific structure of the conveying assembly 31 is disclosed. The conveying assembly 31 includes a vent hole opened on the top of the settling tank 3. A conveying cylinder 301 is fixedly installed inside the vent hole. An installation plate 302 is fixedly installed on the top of the conveying cylinder 301. A discharge port 306 is opened on the top of the outer surface of the conveying cylinder 301. A drive motor 303 is installed on the top of the installation plate 302. A rotating shaft 304 is installed through the bottom of the output shaft of the drive motor 303 and the outer surface of the rotating shaft 304 is fixedly installed with a spiral blade 305.

[0030] The bottom of the conveying cylinder 301 is located at the bottom of the inner wall of the settling tank 3, and the rotating shaft 304 is installed inside the conveying cylinder 301.

[0031] Furthermore, a vent hole is formed at the top of the conveying assembly 31, and the conveying cylinder 301 is fixedly installed inside the vent hole, so that the bottom of the conveying cylinder 301 is located at the bottom of the inner wall of the settling tank 3, and the top of the conveying cylinder 301 extends to the top of the settling tank 3, and is fixedly connected to the mounting plate 302, so that the mounting plate 302 seals the top of the conveying cylinder 301. A discharge port 306 is formed at the top of the outer surface of the conveying cylinder 301, which can discharge impurities conveyed by the spiral blades 305 inside the conveying cylinder 301. This allows the drive motor 303 to be installed on the top of the mounting plate 302. Furthermore, the output shaft of the drive motor 303 passes through the conveying cylinder 301 and is connected to the rotating shaft 304. The outer surface of the rotating shaft 304 is equipped with a spiral blade 305. A drain outlet 4 is opened at the bottom of the sedimentation tank 3, so that the sewage entering the sedimentation tank 3 will flow out from the drain outlet 4. As a result, the impurities in the sewage will accumulate at the bottom of the inner wall of the sedimentation tank 3. The drive motor 303 drives the rotating shaft 304 and the spiral blade 305 to rotate, which can spirally convey the impurities at the bottom of the sedimentation tank 3 to the discharge outlet 306 of the conveying cylinder 301 for discharge, thereby achieving the effect of sedimentation, discharge and conveying of impurities in sewage.

[0032] It should be noted that the wastewater in the sedimentation tank 3 will not be higher than the height of the conveying cylinder 301, so that the spiral blades 305 can spirally convey and discharge the impurities in the wastewater from the conveying cylinder 301.

[0033] Secondly, considering the issue of how to ensure that impurities in the wastewater accumulate to the bottom of the inner wall of sedimentation tank 3 after entering the wastewater, the following should be provided: Figure 4 and Figure 5 The bottom of the sedimentation tank 3 is provided with a drain outlet 4, and a collar 41 is fixedly installed at the bottom of the drain outlet 4. A filter plate 42 is installed on the bottom of the inner wall of the collar 41.

[0034] A rotating rod 5 is installed on the top of the filter plate 42. A connecting rod 51 is fixedly installed on the top of the rotating rod 5. A connecting sleeve 52 is installed on the top of the connecting rod 51. The connecting sleeve 52 is installed at the bottom of the rotating shaft 304.

[0035] Furthermore, a collar 41 is installed on the outside of the drain outlet 4 at the bottom of the sedimentation tank 3, so that the filter plate 42 can be fixedly installed inside the collar 41. When sewage flows out from the drain outlet 4, the impurities in the sewage will be blocked by the filter plate 42, causing the impurities in the sewage to accumulate at the bottom of the inner wall of the sedimentation tank 3. They can be stirred and transported by the spiral blades 305. After the impurities accumulate at the bottom of the inner wall of the sedimentation tank 3, they will clog the filter screen and then clog the drain outlet 4, preventing the sewage from flowing out. The rotating rod 5 is set on the top of the filter plate 42, and the rotating rod 5 is connected to the rotating shaft 304 through the connecting rod 51 and the connecting sleeve 52. The rotation of the rotating shaft 304 can drive the rotating rod 5 to rotate together, which can scrape away the impurities on the top of the filter plate 42, preventing the impurities from clogging the filter plate 42, and achieving the effect of settling the impurities inside the sewage and transporting them out of the sedimentation tank 3.

[0036] Finally, considering that the filtered wastewater still needs to be discharged into a biodegradation tank or chemical decomposition tank for further purification of minute impurities, [the following is provided] Figure 1 A water supply pipe 6 is installed at the bottom of the drain outlet 4. A second booster pump 61 is installed at the outlet end of the water supply pipe 6. A second water supply pipe 62 is installed at the top of the second booster pump 61. A control box 7 is installed on the top of the sedimentation tank 3. The control box 7 is used to control the start and stop of the drive motor 303, the first booster pump 21 and the second booster pump 61.

[0037] Furthermore, a water supply pipe 6 is installed at the bottom of the bottom collar 41 of the drain outlet 4, so that the water supply pipe 6 can be connected to the second pressurized water pump 61. The second pressurized water pump 61 is powered on and pressurizes and transports the sewage from the water supply pipe 62 to the biodegradation tank or chemical decomposition tank for filtration and purification, achieving the effect of a second pressurization and transportation of sewage. The control box 7 installed on the top of the sedimentation tank 3 can be wired to the drive motor 303, the first pressurized water pump 21 and the second pressurized water pump 61, and receive signals to control the start and stop of the drive motor 303, the first pressurized water pump 21 and the second pressurized water pump 61.

[0038] It should be noted that biodegradation tanks and chemical decomposition tanks can purify wastewater. Biodegradation tanks and chemical decomposition tanks are existing technologies, and their working principles are common knowledge to those skilled in the art, so they will not be elaborated here.

[0039] In summary, the working principle of this utility model is as follows:

[0040] When transporting and filtering sewage, the sewage is discharged into the primary sedimentation tank 1 through the inlet pipe 11. The sewage then passes through a grid filter plate 12 with multiple filter holes of different sizes, and the impurities inside the sewage are initially filtered and settled to the bottom of the primary sedimentation tank 1. The initially filtered sewage is discharged from the outlet pipe 2 and is pressurized and quickly transported into the sedimentation tank 3 by the first pressurization pump 21 to avoid the problem of slow flow due to excessive impurities in the sewage. When the sewage enters the sedimentation tank 3, the control box 7 controls the drive motor 303 to start working, driving the rotating shaft 304 and the spiral blade 305 to rotate. At the same time, the sewage flows out from the collar 41 at the bottom of the drain outlet 4. The filter plate 42 inside the collar 41 can filter the impurities inside the sewage and accumulate the impurities to the bottom of the inner wall of the sedimentation tank 3. Then, the rotation of the spiral blade 305 can transport the impurities in the conveying cylinder 301, so that the impurities are discharged from the discharge port 306, achieving the effect of further sedimentation and filtration of impurities in the sewage and transporting the settled impurities out of the sedimentation tank 3.

[0041] When wastewater flows out through filter plate 42, impurities accumulate on top of filter plate 42 and block it. Connecting sleeve 52 can be fitted and fixed to the bottom of rotating shaft 304. Rotation of rotating shaft 304 will drive connecting sleeve 52, connecting rod 51 and rotating rod 5 to rotate together. In turn, rotating rod 5 will push aside the impurities accumulated on top of filter plate 42, preventing impurities from blocking filter plate 42. This achieves the effect of accelerating the flow of wastewater discharged from sedimentation tank 3 through a second pressurization pump 61, and settling and filtering out impurities in the wastewater.
