Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an automated wastewater treatment device. Background Technology

[0002] Wastewater treatment involves using physical, chemical, and biological methods to purify wastewater, reduce pollution, and ultimately achieve wastewater recycling and reuse, thus making full use of water resources.

[0003] For example, in the prior art, an automated wastewater treatment device, publication number CN219314680U, wastewater is introduced into the filter tank through the wastewater inlet pipe. The filtered wastewater is then sent to the sedimentation tank. Once the tank is full, the pumping stops, the fourth valve opens, and water treatment agent is added to the sedimentation tank. The first motor starts, the stirring rod rotates, and after thorough stirring, the sediment is allowed to settle. After sedimentation, the clear water from the sedimentation tank is discharged through the outlet pipe. Then, the second and third valves are opened to send the sediment into the outer shell. Finally, the second motor starts, and the conveyor belt sends the sediment out. The wastewater in the outer shell can be pumped back to the filter tank. The conveyor belt is inclined inside the outer shell, and the sediment in the filter tank and sedimentation tank falls onto the conveyor belt. The conveyor belt extends from one end of the outer shell, sending the sediment out of the outer shell. A pressure roller is rotatably connected inside the outer shell. The pressure roller is pressed onto the conveyor belt and is located on the left side below the filter tank. Before being sent out of the outer shell, the sediment needs to be rolled by the pressure roller to remove as much water as possible from the sediment.

[0004] This device uses pressure rollers pressed onto the conveyor belt to roll and remove moisture from the sediment on the conveyor belt. However, when there are large components in the sediment, because the distance between the pressure rollers and the conveyor belt is fixed, some sediment may not be able to pass through the gap between the pressure rollers and the conveyor belt smoothly. At this time, the sediment will be blocked and will be difficult to continue to move forward with the conveyor belt. As a result, it will keep sliding on the conveyor belt and cannot be effectively transported out and dehydrated, which affects the device's separation and delivery effect on the sediment. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose an automated wastewater treatment device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automated wastewater treatment device, comprising a housing, a sedimentation and conveying mechanism disposed within the housing, a dewatering mechanism disposed at the tail end of the sedimentation and conveying mechanism, the dewatering mechanism comprising two belt conveyors fixed to the housing, the two belt conveyors being respectively located on the upper and lower sides of the sedimentation and conveying mechanism, a fixed plate fixed to the housing being disposed between the two belt conveyors, a plurality of guide sleeves linearly arrayed along the conveying direction of the belt conveyors being fixedly connected through the fixed plate, a movable block being slidably connected within the guide sleeve, a through groove being opened on one side of the movable block, a guide groove communicating with the through groove being opened on the opposite side of the movable block, a U-shaped rod being fixedly connected to the bottom end of the guide sleeve and slidably connected to the guide groove, an mounting plate being fixedly connected to the side of the U-shaped rod away from its opening end, an insert rod being fixedly connected to the bottom end of the mounting plate, an insertion hole for inserting the insert rod being opened at the bottom of the through groove, a top plate being fixedly connected to the top of the movable block, a spring rod being fixedly connected between the top plate and the fixed plate, and a plurality of evenly distributed wedges being fixedly connected to the conveyor belt of the belt conveyor located above.

[0007] Preferably, the sedimentation conveying mechanism includes a chain conveyor, on which a hopper is fixedly connected, and the hopper has a plurality of evenly distributed water outlet holes.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up a dewatering mechanism consisting of two belt conveyors, a fixed plate, a guide sleeve, a moving block, a wedge, a spring rod, etc., efficient and automated dewatering of sediment is achieved.

After the wedge is disengaged, the spring rod drives the moving block to reset, and the insert rod pushes out the adhered sediment. It can effectively dewater and adapt to the larger components that may exist in the sediment, avoiding obstruction of conveying or dewatering.

[0015] 2. In this utility model, a sedimentation conveying mechanism consisting of a chain conveyor, a hopper, and a water outlet is set up. Combined with a transmission mechanism, it achieves synchronous operation with the belt conveyor. The hopper intercepts and carries the sediment and conveys it, while the water outlet performs preliminary dewatering. The transmission mechanism ensures that the sedimentation conveying and dewatering processes work together, thereby improving the overall automation level and processing efficiency of the device.

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figure 1-4 As shown, an automated wastewater treatment device includes a housing 1. A sedimentation and conveying mechanism is installed inside the housing 1. A dewatering mechanism is installed at the tail end of the sedimentation and conveying mechanism. The dewatering mechanism includes two belt conveyors 6 fixed to the housing 1, located on the upper and lower sides of the sedimentation and conveying mechanism, respectively. A fixed plate 9, fixed to the housing 1, is installed between the two belt conveyors 6. Several guide sleeves 8, linearly arrayed along the conveying direction of the belt conveyors 6, are fixedly connected through the fixed plate 9. Moving blocks 19 are slidably connected inside the guide sleeves 8. A through groove 22 is provided on one side of each moving block 19. On the opposite side of the movable block 19, a guide groove 15 communicating with the through groove 22 is provided. A U-shaped rod 20 that is slidably connected to the guide groove 15 is fixedly connected to the bottom end of the guide sleeve 8. A mounting plate 21 is fixedly connected to the side of the U-shaped rod 20 away from its opening end. A plug rod 12 is fixedly connected to the bottom end of the mounting plate 21. A plug hole 23 for plugging into the plug rod 12 is provided at the bottom of the through groove 22. A top plate 18 is fixedly connected to the top of the movable block 19. A spring rod 17 is fixedly connected between several top plates 18 and fixed plates 9. Several evenly distributed wedges 7 are fixedly connected to the conveyor belt of the belt conveyor 6 located above.

[0024] In this technical solution, when the belt conveyor 6 above is running, the wedge 7 on its conveyor belt will move with the conveyor belt. As the wedge 7 moves, when the wedge 7 contacts the top plate 18 and continues to push, the top plate 18 will drive the moving block 19 to slide downward in the guide sleeve 8. At this time, the spring rod 17 is compressed and stores elastic potential energy. During the downward sliding process of the moving block 19, since the U-shaped rod 20 is slidably connected with the guide groove 15, the moving block 19 will move downward along the U-shaped rod 20, causing the insertion hole 23 to separate from the insertion rod 12. Then the moving block 19 moves downward to press the sediment and dehydrate the sediment. When the wedge 7 is separated from the top plate 18, the spring rod 17 resets, thereby driving the moving block 19 to reset, driving the insertion rod 12 to re-insert into the insertion hole 23, and pushing out the sediment stuck to the bottom of the moving block 19.

[0025] like Figure 3 As shown, the sedimentation conveying mechanism includes a chain conveyor 11, on which a hopper 13 is fixedly connected, and the hopper 13 has several evenly distributed water outlet holes 14.

[0026] In this technical solution, when the chain conveyor 11 is working, its chain will drive the hopper 13 fixed on it to move together. The hopper 13 can intercept and carry the sediment in the wastewater flowing in from the top of the outer shell 1, and transport the sediment from the front end of the device to the dewatering mechanism at the rear end. When the hopper 13 carries the sediment and moves, the water contained in the sediment can be discharged through these water outlet holes 14 to achieve the initial dewatering of the sediment.

[0027] like Figure 2 and Figure 3 As shown, the belt conveyor 6 and the chain conveyor 11 are connected by a transmission mechanism. The transmission mechanism includes pulleys 16 that are fixed to the drive roller of the belt conveyor 6 and the sprocket of the chain conveyor 11. The two pulleys 16 are driven by belt strips. A motor 5 is fixedly connected to the outside of the housing 1. The main shaft of the motor 5 passes through the side wall of the housing 1 and is fixed to the sprocket of the chain conveyor 11.

[0028] In this technical solution, the motor 5 serves as the power source. When its main shaft rotates, it directly drives the sprocket of the chain conveyor 11 to rotate, thereby driving the entire chain conveyor 11 to operate. Since the sprocket of the chain conveyor 11 is fixed to one of the pulleys 16, the pulley 16 rotates synchronously with the sprocket; while the other pulley 16 is fixed to the drive roller of the belt conveyor 6, and the two pulleys 16 are driven by an externally fitted belt strip, when the sprocket of the chain conveyor 11 rotates, the power is transmitted to the drive roller of the belt conveyor 6 through the pulley 16 and the belt strip, driving the belt conveyor 6 to operate.

[0029] Furthermore, the pulley 16 and belt in this technical solution can be replaced by sprockets and chains, and the motor 5 in this technical solution is preferably a three-phase asynchronous motor.

[0030] like Figure 2 As shown, a sewage outlet 2 is provided on the outer casing 1, and the tail end of the belt conveyor 6 located below is set inside the sewage outlet 2.

[0031] In this technical solution, the sewage outlet 2 provides a discharge channel for the sediment after dewatering, and the tail end of the belt conveyor 6 below is set inside the sewage outlet 2, which can ensure that the sediment after being treated by the dewatering mechanism can be directly transported to the sewage outlet 2 by the conveying action of the belt conveyor 6, and finally discharged from the outside of the device from the sewage outlet 2.

[0032] like Figure 2 As shown, a guide plate 10 is fixedly connected to the inner side of the outer casing 1 and above the head end of the chain conveyor 11.

[0033] In this technical solution, when wastewater and sediment enter the outer shell 1, the guide plate 10 can guide them to fall accurately into the intercepting hopper 13, preventing wastewater and sediment from spreading or splashing into other areas inside the outer shell 1, and ensuring that the sediment can be effectively intercepted and carried by the intercepting hopper 13.

[0034] like Figure 2 As shown, it also includes a filter tank 4, and a water pump 3 is fixedly connected to the inside of the outer shell 1 and below the chain conveyor 11. The water inlet of the water pump 3 is connected to the inside of the outer shell 1, and the water outlet is connected to the inside of the filter tank 4.

[0035] In this technical solution, when the hopper 13 on the chain conveyor 11 intercepts and transports the sediment in the wastewater, the clean water in the wastewater will flow through the water outlet 14 on the hopper 13 to the bottom of the outer shell 1. At this time, the water pump 3 located below the chain conveyor 11 starts, and its inlet end sucks in the water collected at the bottom of the outer shell 1, and then transports the water to the inside of the filter tank 4 through the outlet end.

[0036] The method of using this utility model is as follows: When in use, the wastewater to be treated is guided by the guide plate 10 and falls into the hopper 13 of the chain conveyor 11. The motor 5 drives the chain conveyor 11 to operate. The hopper 13 intercepts and transports the sediment. The water flows through the outlet hole 14 to the bottom of the outer shell 1, completing the initial dewatering. The sediment is sent to the dewatering mechanism and falls between the upper and lower belt conveyors 6. The motor 5 drives the belt conveyor 6 to operate through the pulley 16 and the belt strip. The wedge block 7 of the upper belt conveyor 6 pushes the top plate 18, causing the moving block 19 to move down. The insertion rod 12 separates from the insertion hole 23, and the moving block 19 presses the sediment to dewater. After the wedge block 7 is released, the spring rod 17 returns to its original position, and the insertion rod 12 pushes out the sediment that is stuck to the bottom of the moving block 19. The dewatered sediment is discharged from the sewage outlet 2 through the lower belt conveyor 6.

[0037] The wiring diagram of motor 5 in this utility model is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of motor 5 will not be explained in detail.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
