Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] Please see Figure 1-5 This utility model provides a skid-mounted tunnel sewage treatment equipment, comprising:

[0036] Skid-mounted base 1, with casters at the four corners of the bottom wall of skid-mounted base 1;

[0037] The body 2 is fixedly mounted on the upper side wall of the skid-mounted base 1. The interior of the skid-mounted base 1 is divided into a filter chamber 22 and a purification chamber 23 by a partition 21.

[0038] Filter plate 3 is installed inside filter chamber 22;

[0039] The guide plate 4 is fixedly installed in the filter chamber 22 and located below the filter screen plate 3. The guide plate 4 is used to allow the wastewater filtered by the filter screen plate 3 to enter the purification chamber 23.

[0040] Conical base 5, the conical base 5 is fixedly installed inside the purification chamber 23;

[0041] Cleaning mechanism 6 is installed on partition 21 and is used to clean the debris on filter screen 3;

[0042] A stirring mechanism 7 is installed inside the purification chamber 23. The stirring mechanism 7 is used to stir and mix the sewage and purification agents.

[0043] Linkage mechanism 8 is installed on the machine body 2. Linkage mechanism 8 is used to drive the cleaning mechanism 6 to run at the same time as the stirring mechanism 7.

[0044] Two collection boxes 9 are respectively set on the outer walls of the two sides of the body 2. The collection boxes 9 are used to collect garbage.

[0045] The above-described structure enables the functions of sewage filtration, purification, garbage disposal, and equipment relocation, making it more practical.

[0046] The cleaning mechanism 6 includes a cavity 61 opened on the side wall of the partition 21 near the filter chamber 22. A reciprocating screw 62 is rotatably provided between the two side walls of the cavity 61. Two guide rods 63 are also fixedly connected between the two side walls of the cavity 61. A movable seat 64 adapted to the reciprocating screw 62 is slidably sleeved between the two guide rods 63. A push plate 65 is fixedly connected to the side wall of the movable seat 64 near the filter plate 3.

[0047] With the above structure, the debris on the filter plate 3 can be automatically cleaned and pushed to both sides of the filter chamber 22 to prevent the filter plate 3 from becoming clogged.

[0048] In this embodiment, a gap of 0.5-1mm is reserved between the lower edge of the push plate 65 and the upper surface of the filter plate 3. This avoids hard contact that could cause wear on the filter and ensures that the waste is pushed out. The movement range of the push plate 65 covers the entire width of the filter plate 3.

[0049] It should be noted that the reciprocating screw 62 has two threaded grooves with the same pitch and opposite directions on its surface. The moving seat 64 is provided with a slider that matches the threaded groove. By rotating the reciprocating screw 62, the side of the helical groove pushes the slider placed in the helical groove to make axial reciprocating motion.

[0050] The stirring mechanism 7 includes an L-shaped mounting plate 71 fixedly mounted on the upper outer wall of the body 2. A drive motor 72 is mounted on the upper inner wall of the L-shaped mounting plate 71. The output shaft of the drive motor 72 is fixedly connected to a transmission rod 73. The lower end of the transmission rod 73 extends into the purification chamber 23 and is fixedly connected to a stirring shaft 74. Multiple stirring blades 75 are evenly arranged on the stirring shaft 74.

[0051] The above structure allows the wastewater and chemicals in the purification chamber 23 to be mixed evenly, accelerating the degradation of pollutants.

[0052] The linkage mechanism 8 includes a worm gear 81 fixedly sleeved on one end of the reciprocating screw 62, a worm 82 rotatably meshing with the worm gear 81 on the lower side wall of the cavity 61, a rotating shaft 83 fixedly connected to the upper end of the worm 82, the upper end of the rotating shaft 83 extending to the top of the machine body 2 and fixedly connected to a driven wheel 84, a driving wheel 85 fixedly sleeved on the upper end of the transmission rod 73, and a toothed belt 86 wound between the driven wheel 84 and the driving wheel 85.

[0053] The above structure allows the mixing mechanism 7 to operate simultaneously with the cleaning mechanism 6, eliminating the need for an additional power source, saving energy and reducing costs.

[0054] The machine body 2 has an inlet 24 on its upper outer wall above the filter chamber 22 for introducing tunnel sewage into the filter chamber 22. The machine body 2 has a dosing port 25 on its upper outer wall above the purification chamber 23 for adding flocculants, disinfectants and other purification agents into the purification chamber 23.

[0055] A support plate 231 is fixedly connected to one side of the outer wall of the body 2. A water pump 232 is installed on the upper side wall of the support plate 231. The input end of the water pump 232 is connected to the purification chamber 23 through a water pumping pipe 233, and the output end is connected to a drain pipe 234.

[0056] With the above structure, the treated clean water in the purification chamber 23 can be extracted and then discharged through the drain pipe 234.

[0057] The bottom of the conical base 5 is connected to a drain pipe 51, and the other end of the drain pipe 51 extends to the outside of the body 2. A solenoid valve 52 is installed on the drain pipe 51.

[0058] With the above structure, the drain pipe 51 is used to discharge the precipitate that has accumulated after flocculation, and the solenoid valve 52 can control the opening and closing of the drain pipe 51, which facilitates timed or on-demand sewage discharge and avoids the accumulation of precipitate from affecting the purification effect.

[0059] The filter chamber 22 has openings on both sides of the filter chamber 22. The discharge plate 221 is fixedly installed on both sides of the outer wall of the machine body 2 at the position of the opening. The garbage pushed by the push plate 65 slides into the collection box 9 through the opening and the discharge plate 221 to ensure smooth garbage collection.

[0060] Two T-shaped mounting slots 26 are provided on both sides of the outer wall of the body 2, and two mounting rails 91 that are adapted to the T-shaped mounting slots 26 are fixedly connected to the outer wall of the collection box 9 on the side of the body 2.

[0061] The above structure allows the collection box 9 to be quickly disassembled and assembled, making it convenient to remove and dispose of garbage.

[0062] The machine body 2 has a controller 10 on one side of its outer wall. The drive motor 72, water pump 232 and solenoid valve 52 are all electrically connected to the controller 10. The controller 10 can control the drive motor 72, water pump 232 and solenoid valve 52.

[0063] In this embodiment, the controller 10 uses an STM32 microcontroller. The input and output pins of the microcontroller are connected to the drive motor 72, the water pump 232 and the solenoid valve 52 as described above. This can be achieved by programming the microcontroller. The circuit and program used are common technologies in the field of microcontrollers. Those skilled in the art can easily derive the specific circuit based on the above control relationship description. Therefore, the specific circuit will not be described in detail in this article.

[0064] It should be noted that this utility model is a skid-mounted tunnel sewage treatment equipment. During use, the equipment is moved to the sewage collection point inside the tunnel by the casters of the skid base 1 to ensure stable placement. Tunnel sewage enters the filter chamber 22 through the inlet 24 and is filtered by the filter screen 3. Large particles of debris, such as stones and plastic fragments, are intercepted on the filter screen 3. The filtered sewage flows into the purification chamber 23 along the guide inclined plate 4. The controller 10 starts the drive motor 72 to run, which drives the cleaning mechanism 6 through the linkage mechanism 8: the drive wheel 85 drives the driven wheel 84, the rotating shaft 83 and the worm 82 to rotate through the toothed belt 86. The worm 82 meshes with the worm wheel 81 to rotate the reciprocating screw 62. The moving seat 64 slides back and forth along the guide rod 63, and the push plate 65 moves synchronously, pushing the debris on the filter screen 3 to both sides of the filter chamber 22. The debris falls into the collection boxes 9 on both sides through the opening and the discharge plate 221. Purifying agents are added to the purification chamber 23 through the dosing port 25. The drive motor 72 of the stirring mechanism 7 drives the transmission rod 73, stirring shaft 74, and stirring blade 75 to rotate, so that the sewage and agents are fully mixed, and the pollutants form flocs and settle to the bottom of the conical base 5. After purification, the water pump 232 is started by the controller 10 to draw the upper layer of clean water in the purification chamber 23 through the water suction pipe 233 and discharge it through the drain pipe 234. After drainage, the solenoid valve 52 is opened by the controller 10, and the sediment at the bottom of the conical base 5 is discharged to the designated collection device through the sewage pipe 51. During the garbage cleaning process, when the collection box 9 is full, it is pulled out along the T-shaped mounting groove 26, the garbage is emptied, and then it can be reinstalled.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
