Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater treatment device for sediment separation. 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. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.

[0003] A filtration and separation treatment device for sludge wastewater, disclosed in publication number CN222266233U, includes: a sludge removal box with a baffle installed at an incline inside; a water pump installed on one side of the sludge removal box and connected to it by a pipeline; a sedimentation tank installed on one side of the water pump; and a drain outlet installed at the bottom of the sedimentation tank. This invention uses a motor to drive multiple sets of screens to rotate within the wastewater, separating sludge and other debris. Furthermore, the use of a coiled pipe ensures that the wastewater flows slowly into the sedimentation tank, preventing splashing of bottom sediment and ensuring the normal operation of the sedimentation tank. Adjusting the position of the screen frames allows for the rapid discharge of some sediment from the sedimentation tank, preventing excessive accumulation and reducing its usability. This structure significantly improves wastewater treatment efficiency.

[0004] A common problem in current wastewater treatment processes is the presence of numerous substances in the wastewater. After settling, these substances form sediments that accumulate on the filter screens during filtration. If left untreated for an extended period, these sediments can clog the filter, severely impacting subsequent filtration operations. To address this, the filter's access door is typically opened for internal cleaning. However, this process is time-consuming and inconvenient. To improve filtration efficiency, multiple filtration cycles are often performed before cleaning the internal components. This inconsistency in timeliness of cleaning can easily lead to severe clogging of the filter pores, further affecting filtration performance.

[0005] Therefore, those skilled in the art have provided a wastewater treatment apparatus for sediment separation to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a wastewater treatment device for sediment separation, so as to solve the problem mentioned in the background art that the existing wastewater treatment devices are not timely enough in treating the filtered sediments.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A wastewater treatment device for sediment separation includes: a filter box with an inlet at the top; a baffle plate fixedly installed inside the filter box, with a filter plate integrally connected inside the baffle plate; a connecting frame rotatably connected to the front wall of the filter box, with a reversing box installed at one end of the connecting frame; a drive motor installed on one side of the reversing box; a comb plate connected to the surface of the connecting frame; a cleaning box fixedly installed on the left side of the filter box; a water tank integrally connected to the bottom of the filter box, with an inclined flow channel fixedly connected to the bottom of the water tank; and a drain pipe inclinedly connected to the front end of the inclined flow channel.

[0009] As a further improvement of this utility model: the drive motor is connected to the connecting frame through the commutator box, and the comb plate and the connecting frame are fixedly connected.

[0010] As a further improvement of this utility model, half of the overall length of the comb plate and the connecting frame is the same as the radius of the pocket plate.

[0011] As a further improvement of this utility model: a rotating shaft is rotatably installed inside the upper part of the cleaning box, and a push plate is fixedly connected to the surface of the rotating shaft.

[0012] As a further embodiment of this utility model: the pusher plate is distributed in a ring about the center line of symmetry about the rotation axis, and the outer edge of the pusher plate is set as a comb tooth structure.

[0013] As a further improvement of this utility model: a filter screen is provided below the pocket plate, and screw connectors are fixedly connected to both ends of the filter screen, and the filter screen is connected to the pocket plate through the screw connectors.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Inside the filter box, several sets of pocket plates are fixedly installed, evenly distributed along the inner wall of the filter box. Filter plates are placed between adjacent pocket plates, and a connecting frame is installed on the side wall of the filter box. The connecting frame is connected to the reversing box. The drive motor reverses the mechanical transmission power through the reversing box, transmitting the mechanical transmission to the connecting frame. A comb plate is connected to the connecting frame via a connecting rod. When the connecting frame rotates, the comb plate pushes and scrapes the filter plates between the pocket plates to clean them. The rotation of the comb plate pushes the sediment to one side of the pocket plate. A rotating shaft is installed on one side of the pocket plate, and a push plate is fixedly connected to the surface of the rotating shaft. The outer edge of the push plate is set with a comb structure, and the gap between the comb teeth of the push plate and the pocket plate is consistent. The rotation of the rotating shaft drives the comb plate to push the sediment pushed from the pocket plate back into the cleaning box, thereby completing the treatment of the sediment inside the filter box in a timely manner and reducing the need to repeatedly open the inside of the filter box, thus improving the cleaning efficiency of sewage sediment.

[0021] 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.

[0022] Please see Figures 1-4This utility model provides a wastewater treatment device for sediment separation, including: a filter box 1, an inlet 2 at the top of the filter box 1, a baffle 11 fixedly installed inside the filter box 1, and a filter plate 14 integrally connected inside the baffle 11, a filter screen 15 below the baffle 11, and screw connectors 16 fixedly connected to both ends of the filter screen 15, and the filter screen 15 is connected to the baffle 11 through the screw connectors 16.

[0023] Specifically, by using screw connector 16, the filter screen 15 is installed below the filter plate 14, ensuring that the filter screen 15 and the filter plate 14 can fit tightly together to form an effective filtration structure. The filter screen 15 can intercept and remove suspended particles and sediments in the sewage. Through the cooperation between the filter plate 14 and the filter screen 15, the filtration efficiency is significantly improved, ensuring that the water quality is better separated and filtered.

[0024] A connecting frame 9 is rotatably connected to the front wall of the filter box 1, and a reversing box 7 is installed at one end of the connecting frame 9. A drive motor 8 is installed on one side of the reversing box 7. A comb plate 10 is connected to the surface of the connecting frame 9. A cleaning box 6 is fixedly installed on the left side of the filter box 1. The drive motor 8 is connected to the connecting frame 9 through the reversing box 7. The comb plate 10 and the connecting frame 9 are fixedly connected. Half of the overall length of the comb plate 10 and the connecting frame 9 is the same as the radius of the pocket plate 11.

[0025] Specifically, filter plates 14 are arranged between the pocket plates 11. When sewage enters the filter box 1, the filter plates 14 filter the sewage and trap sediment. The drive motor 8 transmits the mechanical power to the connecting frame 9 through the reversing box 7, thereby driving the connecting frame 9 to rotate. Since the overall length and diameter of the connecting frame 9 and the comb plate 10 are the same as the radius of the pocket plates 11, when the connecting frame 9 drives the comb plate 10 to rotate, the comb teeth on the comb plate 10 will engage between the pocket plates 11 when rotating clockwise. The width of the comb teeth is the same as the width of the filter plates 14 between the pocket plates 11, and they will be embedded between the pocket plates 11. As the connecting frame 9 rotates, the trapped sediment is pushed to the left side of the filter box 1 until it is pushed to the left end of the pocket plate 11.

[0026] A water tank 3 is integrally connected to the bottom of the filter box 1, and a flow channel 4 is fixedly connected to the bottom of the water tank 3. A drain pipe 5 is inclinedly connected to the front end of the flow channel 4. A rotating shaft 12 is rotatably installed inside the cleaning box 6, and a push plate 13 is fixedly connected to the surface of the rotating shaft 12. The push plate 13 is distributed in a ring about the symmetrical center line of the rotating shaft 12, and the outer edge of the push plate 13 is set as a comb tooth structure.

[0027] Specifically, the upper interior of the cleaning box 6 is connected to the interior of the filter box. A rotating shaft 12 is installed at the position where the cleaning box 6 and the filter box are connected. A push plate 13 is provided on the surface of the rotating shaft 12. The outer edge of the push plate 13 is set as a comb tooth structure. This comb tooth structure is consistent with the comb tooth structure on the comb tooth plate 10 and matches the spacing size between it and the pocket plate 11, so that the pushed sediment is pushed clockwise into the cleaning box 6 and then discharged through the cleaning box 6.

[0028] The working principle of this utility model is as follows:

[0029] When using this invention, wastewater first enters the filter box 1 and undergoes preliminary filtration through the filter plate 14, where sediment is trapped. Then, the drive motor 8 starts, transmitting mechanical power to the connecting frame 9 via the reversing box 7, causing the connecting frame 9 to rotate. The comb plate 10 on the connecting frame 9 rotates accordingly, its comb structure engaging with the filter plates 14 between the pocket plates 11, effectively pushing the trapped sediment towards the left side of the filter box 1. When the sediment is pushed to the left end of the pocket plate 11, the drive device drives the rotation... The rotating shaft 12 rotates, and the push plate 13 on the rotating shaft 12 pushes the sediment clockwise out of the filter box 1 and into the cleaning box 6 for discharge. At the same time, the filter screen 15 below the baffle plate 11 further intercepts suspended particles and sediments in the sewage, forming an effective filtration structure with the filter plate 14. The filtered water falls into the water tank 3, and the water is introduced into the drain pipe 5 through the inclined flow channel 4 at the bottom of the water tank 3 and discharged through the drain pipe 5, which improves the overall filtration efficiency. The whole device has a compact structure, is easy to operate, and can effectively achieve sediment separation and sewage purification.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
