Description

Technical Field

[0001] This invention belongs to the field of fecal sewage treatment technology, specifically a fecal sewage treatment device. Background Technology

[0002] With the acceleration of urbanization and the increase in population density, the problem of sewage treatment has become increasingly prominent. Traditional sewage treatment methods mostly use simple sedimentation tanks or septic tanks for natural sedimentation and separation. These methods have low solid-liquid separation efficiency, long treatment cycles, and are prone to clogging of filter screens or pores, leading to poor equipment operation and high maintenance costs. In addition, the separated solid feces have a high water content, which is not conducive to subsequent resource utilization (such as composting, incineration, etc.) and may cause secondary pollution.

[0003] In recent years, although some sewage treatment equipment with mechanical extrusion or vibration filtration devices has emerged, it generally suffers from the following shortcomings: First, there is a lack of effective anti-clogging mechanisms during the solid-liquid separation process, and fibers and particles in the sewage easily clog the filter pores, affecting the liquid permeation rate; second, the transportation of the separated solid materials is inconvenient, relying mostly on manual cleaning, resulting in low automation; third, there is a lack of drying treatment for solid sewage, leading to its large volume, easy perishability, and unfavorable storage and transportation; fourth, dehydration is incomplete, and relying solely on gravity filtration is insufficient to further reduce the moisture content of the sewage, limiting resource recovery efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a fecal sewage treatment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fecal sewage treatment device, comprising a separation box and a squeezing box, wherein a support plate is fixedly connected to the separation box, and a vibration mechanism for improving the efficiency of fecal solid-liquid separation is installed on the support plate;

[0006] The vibration mechanism includes a motor, which is fixedly connected to a support plate. The output end of the motor is fixedly connected to a drive shaft, which is rotatably connected to the separation box. A cam is fixedly connected to the end of the drive shaft away from the motor. Slide grooves are provided on both sides inside the separation box, and telescopic rods are fixedly connected in the slide grooves. A slider is fixedly connected to the end of the telescopic rod away from the slide groove, and a return spring is fixedly connected to the slider. The end of the return spring away from the slider is fixedly connected to the slide groove, and the return spring is sleeved on the telescopic rod. A filter plate for solid-liquid separation of feces is fixedly connected to the slider.

[0007] As a further preferred embodiment of this technical solution: the drive shaft is equipped with a transport and drying mechanism for transporting and drying feces, and the transport and drying mechanism includes a first pulley, which is rotatably connected to the drive shaft, and a transmission belt is meshed on the first pulley. At the same time, a second pulley is meshed on the end of the transmission belt away from the first pulley. A drive shaft is fixedly connected to the second pulley, and the drive shaft is rotatably connected to the separation box. At the same time, an auger for lateral transport of feces is fixedly connected to the drive shaft. A square shell is fixedly connected to the separation box, and the end of the drive shaft away from the separation box is rotatably connected to the square shell. A drying heating lamp for drying feces is installed on the top of the square shell.

[0008] As a further preferred embodiment of this technical solution: a manure discharge pipe for discharging material is fixedly connected to the bottom of the square shell at the end away from the separation box, and the end of the manure discharge pipe away from the square shell is fixedly connected to the extrusion box.

[0009] As a further preferred embodiment of this technical solution: the bottom of the separation box is fixedly connected to a support leg, and a hydraulic rod is fixedly connected to the support leg. At the same time, the hydraulic rod is fixedly connected to the squeezing box through the support leg. The telescopic end of the hydraulic rod is fixedly connected to a push plate for squeezing the feces, and the push plate is slidably connected to the squeezing box.

[0010] As a further preferred embodiment of this technical solution: a connecting pipe is fixedly connected through the top of the separation box, and the connecting pipe is fixedly connected to the drain pipe of the house by a clamp;

[0011] As a further preferred embodiment of this technical solution: both ends of the filter plate are fixedly connected to telescopic guide plates for collecting feces, and the telescopic guide plates are slidably connected to the separation box;

[0012] As a further preferred embodiment of this technical solution: a water outlet pipe for discharging liquid is fixedly connected through the separation box, and a solenoid valve for controlling the discharge of liquid is installed on the water outlet pipe.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In this invention, a vibration mechanism is set on the separation box, and the cam is driven by a motor to rotate the shaft, causing the filter plate to vibrate periodically. At the same time, the telescopic rod, the return spring and the slider reciprocate in the slide groove, which further assists the filter plate to stabilize the vibration, effectively prevents feces from clogging the filter holes, accelerates the liquid permeation speed, and significantly improves the efficiency and thoroughness of solid-liquid separation.

[0015] 2. In this invention, the design of the transport and drying mechanism utilizes a belt drive system to transmit the power of the vibration mechanism to the active rotating shaft, driving the auger to rotate within the square shell. This achieves automatic lateral transport of the separated solid feces. Simultaneously, a drying heating lamp is installed on the top of the square shell to heat and dry the feces during transport, reducing its moisture content and facilitating subsequent storage or resource utilization, while reducing the risk of secondary pollution. Furthermore, a push plate driven by a hydraulic rod is installed inside the compression box to perform secondary mechanical compression on the initially separated feces, further removing residual moisture, improving the dry matter recovery rate, reducing waste volume, and facilitating subsequent composting or incineration.

A drive shaft 54 ​​is fixedly connected to the second pulley 53, and the drive shaft 54 ​​is rotatably connected to the separation box 1. At the same time, an auger 55 for lateral transport of feces is fixedly connected to the drive shaft 54, and a square shell 56 is fixedly connected to the separation box 1. The end of the drive shaft 54 ​​away from the separation box 1 is rotatably connected to the square shell 56, and a drying heating lamp 57 for drying feces is installed on the top of the square shell 56.

[0028] Further: There are four sets of drying heating lamps 57, which are horizontally distributed on the square shell 56. At the same time, the tail end of the square shell 56 is provided with a discharge port, which is located directly above the manure discharge pipe 6.

[0029] In this embodiment, specifically: a manure discharge pipe 6 for discharging material is fixedly connected to the bottom of the square shell 56 away from the separation box 1, and the end of the manure discharge pipe 6 away from the square shell 56 is fixedly connected to the extrusion box 2.

[0030] In this embodiment, specifically: a support leg 7 is fixedly connected to the bottom of the separation box 1, and a hydraulic rod 8 is fixedly connected to the support leg 7.

[0031] Further: There are two sets of hydraulic rods 8, and the two sets of hydraulic rods 8 are respectively installed on the support legs 7 at both ends of the bottom left side of the separation box 1;

[0032] In this embodiment, specifically: a connecting pipe 10 is fixedly connected through the top of the separation box 1, and the connecting pipe 10 is fixedly connected to the drain pipe of the house by a clamp 11.

[0033] Furthermore: The clamp 11 is equipped with a sealing strip inside to prevent sewage leakage at the interface between the connecting pipe 10 and the drain pipe;

[0037] Working principle or structural principle: First, the connecting pipe 10 is connected to the drain pipe of the house through the clamp 11.

The output end of the motor 41 drives the drive shaft 42 to rotate. The rotation of the drive shaft 42 drives the cam 43 to rotate and continuously lift the filter plate 48. With the reset action of the telescopic rod 45 and the return spring 47, the filter plate 48 vibrates, thereby effectively preventing sewage from clogging the filter holes, accelerating the liquid permeation speed, and significantly improving the efficiency and thoroughness of solid-liquid separation. Subsequently, the rotation of the drive shaft 42 drives the first pulley 51 to rotate. The rotation of the first pulley 51 drives the transmission belt 52 to rotate. The rotation of belt 52 drives the rotation of the second pulley 53, which in turn drives the rotation of the drive shaft 54, which in turn drives the auger 55. This transports the filtered feces from the separation box 1 into the square shell 56, where it is dried by the heating of the drying lamp 57. When the feces reach the end of the square shell 56, they fall into the discharge pipe 6 and eventually enter the compression box 2. Then, the hydraulic rod 8 is activated, and its extension end drives the push plate 9 to compress the dried feces, thereby improving the dry matter recovery rate and reducing the waste volume, which is beneficial for subsequent composting or incineration. The filtered urine is discharged from the outlet pipe 13 for the next sterilization operation.
