Description

Technical Field

[0001] This application relates to the technical field of wastewater treatment, and in particular to a waste removal device for rural wastewater treatment. Background Technology

[0002] In my country's rural areas, residents are mostly scattered, and there are significant differences in economic conditions, lifestyles, and habits across regions, as well as varying geographical environments. Therefore, wastewater treatment methods need to be tailored to local conditions and rationally arranged according to specific circumstances.

[0003] In areas where farmers are relatively concentrated and the terrain has a certain difference, the domestic sewage generated by each household can be collected into the catchment area through the fence well. After being filtered for impurities, it is then treated by the underground anaerobic biogas digester.

[0004] In particular, rural areas have a large amount of floating impurities and sedimentary impurities such as gravel. Therefore, there is an urgent need to develop a good impurity removal device for use in conjunction with sewage treatment. Utility Model Content

[0005] The purpose of this application is to provide a waste removal device for rural sewage treatment to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides a wastewater removal device for rural sewage treatment, employing the following technical solution:

[0007] A wastewater treatment device for rural areas includes a gate trough, a bar screen, and a wastewater filtration mechanism. Both the bar screen and the wastewater filtration mechanism are located at the outlet of the gate trough. The wastewater filtration mechanism includes a tank body, a filter cylinder, a geared motor, and a discharge trough. A support is fixed to the top of the tank body, and the filter cylinder is rotatably connected to the support. The geared motor is fixed to the tank body and drives the filter cylinder to rotate. A guide trough is connected to the outlet of the gate trough, with one end extending into the filter cylinder and the other end extending into the filter cylinder. The discharge trough is located at the top of the guide trough.

[0008] The main body of the filter cylinder is made of welded round tube, and the filter cylinder has annular baffles at both ends.

[0009] Preferably, the filter cartridge has multiple baffles evenly arranged inside.

[0010] By adopting the above technical solution, the baffle can block the garbage during the upward rotation process, so that the garbage can fall onto the discharge chute more effectively.

[0011] Preferably, a high-pressure water pipe is provided at the top of the filter cylinder along the length of the circular tube, and multiple high-pressure nozzles are evenly installed at the bottom end of the high-pressure water pipe.

[0012] By adopting the above technical solution and by setting high-pressure nozzles, the pump body connected to the high-pressure water pipe can work intermittently during actual use. The jet of water sprayed from the high-pressure nozzles can wash the gaps between the round tubes on the surface of the filter cartridge, avoiding the residue of impurities and affecting the water output effect.

[0013] An external gear ring is fixed to the outer wall of the filter cylinder, and a gear that meshes with the external gear ring is fixed to the end of the output shaft of the geared motor.

[0014] Preferably, in order to facilitate the operation and installation of the bar screen cleaner, a crossbeam is provided at the top of the gate slot, the bar screen cleaner is installed on the crossbeam, and a distance is left between the bottom end of the bar screen cleaner and the bottom wall of the gate slot.

[0015] In summary, this application includes at least one of the following beneficial technical effects: the rural sewage treatment impurity removal device removes suspended garbage from the upper layer of sewage by setting up a bar screen and filters out large particulate impurities that settle to the bottom by using an impurity filtration mechanism. The whole process has a good impurity removal effect, a high degree of automation, and facilitates subsequent sewage treatment. Attached Figure Description

Detailed Implementation

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses a waste removal device for rural sewage treatment, referring to... Figure 1-3The system includes a gate trough 1, a bar screen cleaner 2, and an impurity filtration mechanism 3. Both the bar screen cleaner 2 and the impurity filtration mechanism 3 are located at the outlet of the gate trough 1. The impurity filtration mechanism 3 includes a tank body 31, a filter cylinder 32, a geared motor 33, and a discharge trough 34. A bracket 35 is fixed to the top of the tank body 31. The filter cylinder 32 is rotatably connected to the bracket 35. The geared motor 33 is fixed to the tank body 31 and is used to drive the filter cylinder 32 to rotate. Specifically, an external gear ring 5 is fixed to the outer wall of the filter cylinder 32. A gear that meshes with the external gear ring 5 is fixed to the end of the output shaft of the geared motor 33. A guide trough 11 is connected to the outlet of the gate trough 1. One end of the guide trough 11 extends into the filter cylinder 32, and one end of the discharge trough 34 also extends into the filter cylinder 32. The discharge trough 34 is located at the top of the guide trough.

[0022] Reference Figure 3 The main body of the filter cylinder 32 is welded from a round tube, and the filter cylinder 32 has annular baffles 321 at both ends. Multiple baffles 322 are evenly arranged inside the filter cylinder 32. During the upward rotation, the baffles 322 can block the garbage, so that the garbage can fall onto the discharge trough 34 more effectively.

[0023] Reference Figure 1 A high-pressure water pipe 4 is provided at the top of the filter cylinder 32 along the length of the circular tube, and multiple high-pressure nozzles 41 are evenly installed at the bottom of the high-pressure water pipe 4.

[0024] With the high-pressure nozzle 41 installed, the pump connected to the high-pressure water pipe 4 can work intermittently during actual use. The jet of water sprayed from the high-pressure nozzle 41 can flush the gaps between the round tubes on the surface of the filter cartridge 32, avoiding the residue of impurities and affecting the water output effect.

[0025] Reference Figure 1 To facilitate the operation and installation of the bar screen cleaner 2, a crossbeam 12 is provided at the top of the gate slot 1. The bar screen cleaner 2 is installed on the crossbeam 12. The garbage intercepted by the bar screen cleaner 2 can fall onto the crossbeam 12 for easy cleaning. In addition, there is a distance between the bottom of the bar screen cleaner 2 and the bottom wall of the gate slot 1.

[0026] The implementation principle of a rural sewage treatment impurity removal device according to an embodiment of this application is as follows:

[0027] Wastewater flows towards the outlet of the gate trough 1. The bar screen 2 can capture and remove the impurities suspended in the upper layer. Then, the wastewater carrying the sedimented impurities flows into the filter cylinder 32. The wastewater flows away through the gaps in the filter cylinder 32, while the impurities are blocked inside the filter cylinder 32. During the rotation of the filter cylinder 32, the impurities can be carried to a high place. The impurities fall onto the discharge trough 34 under their own gravity. The whole process has a good impurity removal effect and a high degree of automation.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
