Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment devices, specifically an integrated sewage treatment equipment. Background Technology

[0002] Wastewater refers to water discharged from domestic and industrial processes that has been polluted to some extent. Water that has lost its original function is simply called wastewater. It mainly consists of water used for domestic purposes, which contains a relatively high amount of organic matter and is relatively easy to treat.

[0003] Currently, the impurities in wastewater are complex, and some impurities are relatively light and easily float during the filtration process, resulting in incomplete removal during scraping. Furthermore, direct discharge can easily cause blockages at the filtration port, thus limiting the effectiveness of this method.

[0004] For example, the integrated sewage treatment equipment disclosed in Chinese Patent Publication No. CN221107219U, through the rotation of a drive motor, can drive the rotation of a rotating rod and an extension shaft. The extension shaft is located directly below the sewage inlet. When sewage enters the sewage treatment tank, larger pieces of waste are suspended on the extension shaft, thus collecting them. Furthermore, the first and second filter screens work together to achieve double filtration, improving the filtration effect. By driving a hydraulic cylinder, the first and second filter screens can be moved out of the sewage treatment tank, making it easy to clean the impurities filtered from the extension shaft, the first filter screen, and the second filter screen, thus improving the convenience of the device.

[0005] Firstly, wastewater contains impurities that emit heat and foul odors, making it easy for these odors to escape during wastewater treatment. If the wastewater is industrial wastewater, the escaping odors can easily threaten the lives of treatment personnel. Furthermore, both industrial and domestic wastewater require the selective introduction of flocculants, demulsifiers, scale inhibitors, or corrosion inhibitors to complete operations such as flocculation, demulsification, and pH adjustment. In this process, the aforementioned devices cannot guarantee that the wastewater can fully react and mix with the added treatment agents. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an integrated wastewater treatment device that solves the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an integrated sewage treatment equipment, including a mixing tank, a treatment agent mixing module is provided inside the mixing tank, and a receiving hopper is inserted into the bottom limit of the mixing tank. The mixing tank is connected to a centrifugal module through the receiving hopper and a solenoid valve installed thereon. The centrifugal module is connected to a treatment module that includes gas washing and drainage operations.

[0008] The treatment agent stirring module includes a drive motor located above the mixing tank. The drive motor is connected to a stirring shaft via a coupling. An array of stirring rods for stirring are welded onto the stirring shaft. Each stirring rod has a mounting groove, and a connecting rod passes through each groove. The other end of each connecting rod is connected via a spring to a slider on which a scraper rod is mounted. In addition to directly filtering wastewater, the addition of the treatment agent stirring module ensures thorough mixing of the added treatment agent and wastewater. Specifically, the drive motor drives the stirring shaft to rotate, and the stirring rods welded to the shaft follow the stirring shaft to mix the pollutants and treatment agent.

[0009] A further improvement of this utility model is that: the connecting rod is limited and installed in the mounting groove and one end is connected to the spring sleeve; the other end of the spring is fixedly connected to the slider; and the other end of the scraper rod is fixedly connected to a scraper with a rubber layer attached. The rubber layer is provided to increase friction and prevent the scraper from being too hard and damaging the inner wall of the mixing tank.

[0010] A further improvement of this utility model's technical solution lies in the following: the centrifuge module includes a horizontally placed centrifuge tank. Inside the centrifuge tank, arranged according to their distance from the inner wall of the tank, there are a first interception layer, a second interception layer, and a centrifuge layer. The inner walls of the first and second interception layers are each provided with interception meshes of different apertures. A centrifuge shaft, with its other end connected to a servo motor via a coupling, is inserted into the centrifuge layer. The aperture of the first interception layer is larger than that of the second interception layer. The first interception layer intercepts larger impurities, and the second interception layer further filters impurities in the wastewater. When the centrifuge shaft is driven by the servo motor, the wastewater inside the centrifuge tank vibrates violently, causing impurities to adhere to the interception mesh to a greater extent, ensuring high filtration efficiency.

[0011] A further improvement of this utility model is that: the outer wall of the mixing tank is limited by a retaining ring, the two ends of the retaining ring are symmetrically welded with suspension arms, and the bottom of the retaining ring is symmetrically provided with a lifting arm for connecting the centrifuge tank, and the two sets of lifting arms are connected by a stabilizing plate.

[0012] A further improvement of this utility model is that the processing module includes a gas washing component for gas washing and a drainage component for drainage. The gas washing component includes a gas extraction pipe that is limited and connected to one end of the centrifuge tank away from the centrifuge shaft. The other end of the gas extraction pipe is connected to a gas pump, and several gas washing bottles are selectively connected to the gas extraction pipe. After the sewage is discharged, the gas extraction pipe extracts the gas inside and connects to the gas washing bottles to wash the gas, so as to avoid the escape of toxic gases during the extraction process and prevent safety accidents.

[0013] A further improvement of the present invention is that the drainage assembly includes a water pumping pipe located at the bottom of the centrifuge tank, the water pumping pipe passes through the centrifuge tank to the middle of the first interception layer and the second interception layer, and the bottom of the water pumping pipe is connected to a water storage tank.

[0014] Beneficial effects

[0015] This utility model provides an integrated wastewater treatment device. Compared with the prior art, it has the following advantages:

[0016] Beneficial effects:

[0017] 1. This integrated sewage treatment equipment, in addition to directly filtering sewage, adds a stirring module to ensure that the added treatment agent is fully mixed with the sewage. In addition, the centrifugal force generated by the torque of the stirring shaft and stirring rod during rotation throws the spring in the installation groove. The spring causes the slider to slide in the installation groove, thus completing the scraping of the inner wall of the mixing tank.

[0018] 2. This integrated sewage treatment equipment uses a first interception layer with a larger pore size than the second interception layer. The first interception layer intercepts larger impurities, and the second interception layer further filters impurities in the sewage. After the centrifugal shaft is driven by a servo motor, the sewage inside the centrifugal tank vibrates violently, causing impurities to adhere to the interception screen to a greater extent, thus ensuring high filtration efficiency.

[0033] 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.

[0034] Reference Figures 1-4 This utility model provides four technical solutions:

[0035] Example 1:

[0036] An integrated wastewater treatment device includes a mixing tank 101a, which is equipped with a treatment agent mixing module. A receiving hopper 101b is inserted into the bottom of the mixing tank 101a. The mixing tank 101a is connected to a centrifugal module through the receiving hopper 101b and a solenoid valve 101c installed thereon. The centrifugal module is connected to a treatment module that includes air washing and drainage operations.

[0037] The agent mixing module includes a drive motor 201a located above the mixing tank 101a. The drive motor 201a is connected to the mixing shaft 201b via a coupling. An array of mixing rods 201c for mixing is welded onto the mixing shaft 201b. The mixing rods 201c are provided with mounting grooves 202a. Each mounting groove 202a has a connecting rod 202b inserted into it. The other end of the connecting rod 202b is connected to a slider 202d on which a scraper rod 202e is mounted via a spring 202c.

[0038] In this embodiment, compared with the prior art, in addition to directly filtering the sewage, a stirring module is added to ensure that the added treatment agent and sewage are fully mixed. The specific solution is as follows: the drive motor 201a drives the stirring shaft 201b to rotate, and the stirring rod 201c welded to the axis follows the stirring shaft 201b to stir and mix the dirt and treatment agent.

[0039] In addition to the above-mentioned technology, this embodiment also provides a solution to prevent impurities from adhering to the inner wall of the mixing tank 101a. Specifically, during the rotation of the stirring shaft 201b and the stirring rod 201c, the centrifugal force generated by their torque throws the spring 202c in the mounting groove 202a. The spring 202c causes the slider 202d to slide in the mounting groove 202a, and the scraper rod 202e installed on it expands to scrape the inner wall of the mixing tank 101a. It should be noted that, under the extreme value of the expansion caused by the spring throwing, the scraper rod 202e also includes one of the following two settings: one is that, under the extreme value, the scraper rod 202e just fits against the inner wall of the mixing tank 101a or the scraper rod 202e collides with the mixing tank 101a.

[0040] Example 2:

[0041] Based on Embodiment 1: the connecting rod 202b is limited and installed at the mounting groove 202a, and one end is sleeved and connected to the spring 202c. The other end of the spring 202c is fixedly connected to the slider 202d. The other end of the scraper rod 202e is fixedly connected to the scraper component 203 with a rubber layer attached.

[0042] The rubber layer is designed to increase friction and prevent the scraper 203 from being too hard and damaging the inner wall of the mixing tank 101a.

[0043] The outer wall of the mixing tank 101a is fitted with a retaining ring 401a. The retaining ring 401a has symmetrically welded hanging arms 401b at both ends. The bottom of the retaining ring 401a is symmetrically provided with a lifting arm 401c for connecting the centrifuge tank 301. The two sets of lifting arms 401c are connected by a stabilizing plate 401d.

[0044] Example 3:

[0045] Based on Embodiment 1 and Embodiment 2: The centrifuge module includes a horizontally placed centrifuge tank 301. The interior of the centrifuge tank 301 is arranged in order of distance from the inner wall of the tank as a first interception layer 301a, a second interception layer 301b, and a centrifuge layer 301c. The inner walls of the first interception layer 301a and the second interception layer 301b are provided with interception meshes 302a of different apertures, and a centrifuge shaft 302b with its other end connected to a servo motor 302c via a coupling is inserted into the centrifuge layer 301c.

[0046] In this embodiment, the pore size of the first interception layer 301a is larger than that of the second interception layer 301b. The first interception layer 301a intercepts larger impurities, and the second interception layer 301b further filters impurities in the wastewater. After the centrifugal shaft 302b is driven by the servo motor 302c, the wastewater inside the centrifugal tank 301 vibrates violently, causing impurities to adhere to the interception net to a greater extent, thus ensuring high filtration efficiency.

[0047] The outer wall of the mixing tank 101a is fitted with a retaining ring 401a. The retaining ring 401a has symmetrically welded hanging arms 401b at both ends. The bottom of the retaining ring 401a is symmetrically provided with a lifting arm 401c for connecting the centrifuge tank 301. The two sets of lifting arms 401c are connected by a stabilizing plate 401d.

[0048] Example 4:

[0049] Based on Embodiment 1 and Embodiment 3: The processing module includes a gas washing assembly for gas washing and a drainage assembly for drainage. The gas washing assembly includes a gas extraction pipe 501a that is limited and connected to one end of the centrifuge tank 301 away from the centrifuge shaft. The other end of the gas extraction pipe 501a is connected to a gas pump 501b, and a number of gas washing bottles 501c are selectively connected to the gas extraction pipe 501a.

[0050] In this embodiment, after the sewage is discharged, the gas inside the extraction pipe 501a is extracted and connected to the gas washing bottle 501c to wash the gas, so as to avoid the escape of toxic gas during the extraction process and the occurrence of safety accidents.

[0051] The drainage assembly includes a water pumping pipe 502a located at the bottom of the centrifuge tank 301. The water pumping pipe 502a passes through the centrifuge tank 301 to the middle of the first intercepting layer 301a and the second intercepting layer 301b. The bottom of the water pumping pipe 502a is connected to the water storage tank 502b.

[0052] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0053] During use, wastewater and treatment agent are added to the mixing tank 101a. The drive motor 201a is started, driving the mixing shaft 201b to rotate. The mixing rod 201c, welded to the shaft, follows the mixing shaft 201b to mix the wastewater and treatment agent. Simultaneously, the centrifugal force generated by the torque of the mixing shaft 201b and the mixing rod 201c during rotation throws the spring 202c in the mounting groove 202a. The spring 202c causes the slider 202d to guide within the mounting groove 202a. During the sliding process, the scraper rod 202e installed on it expands to scrape the inner wall of the mixing tank 101a. Finally, the solenoid valve 101c is activated, and the sewage enters the centrifuge tank 301 and gradually passes through the first interception layer 301a, the second interception layer 301b, and the centrifuge layer 301c. At this time, the centrifuge shaft 302b is driven by the servo motor 302c, which causes the sewage inside the centrifuge tank 301 to vibrate violently, causing impurities to adhere to the interception net to a large extent. Finally, the sewage is extracted from the pumping pipe 502a.
