Description

Technical Field

[0001] This utility model relates to the field of solid waste treatment equipment technology, and in particular to a solid waste pressing device for a front-mounted bar screen. Background Technology

[0002] With the acceleration of urbanization and increasingly stringent environmental protection requirements, the treatment of solid waste generated by sewage treatment plants and garbage transfer stations has become a critical link. Traditional solid waste treatment methods, such as manual cleaning and simple stacking, suffer from low efficiency, high risk of secondary pollution, and high transportation costs. Therefore, there is a need to design a solid waste pressing device for pre-screening.

[0003] To address this, patent CN213644394U discloses a pressing device for solid waste, comprising a support frame and a pressing box. A motor is fixedly connected to the lower end of the support frame, and a geared motor is fixedly connected to the upper surface of the support frame above the motor. A protective cover is fixedly connected to one side of the geared motor. The pressing box is fixedly connected to the upper surface of the support frame, located to the side of the geared motor. A scraper is slidably connected to the upper surface of the pressing box, and a water tank is fixedly connected to the upper surface of the pressing box. A water pump is fixedly connected to one end of the upper surface of the water tank, and a tailstock is fixedly connected to the upper surface of the support frame away from the geared motor. This pressing device for solid waste allows for easier cleaning of the pressing box. When discharging the pressed material, residual waste at the bottom of the pressing box can be scraped clean, facilitating effective and rapid cleaning and saving cleaning time.

[0004] Although the aforementioned pressing device for solid waste can facilitate quick cleaning of residual waste residue after use, the crushed solid waste is prone to remain inside the box during feeding, making it inconvenient to send it into the pressing box. Therefore, it is necessary to design a solid waste pressing device for the front grid. Utility Model Content

[0005] The purpose of this invention is to provide a solid waste pressing device for a front-mounted grid, which solves the problem that in existing solid waste pressing devices, the crushed solid waste is easily left inside the box during feeding, making it inconvenient to send it into the pressing box.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a solid waste pressing device for a front-mounted grid, comprising a pressing assembly;

[0007] A feeding assembly is fixed on one side of the pressing assembly;

[0008] The feeding assembly is fixed with a pushing structure on the side away from the pressing assembly. The pushing structure includes a mounting plate fixed to the outer wall of one side of the feeding assembly. A threaded sleeve is slidably connected to one side of the top of the mounting plate. One end of the threaded sleeve extends into the interior of the feeding assembly and is fixedly connected to a push plate.

[0009] The threaded sleeve is internally threaded with a lead screw. A servo motor is fixedly installed on the bottom of the mounting plate away from the feeding assembly. The output end of the servo motor extends to the top of the mounting plate and is fixedly connected to a first bevel gear. A second bevel gear is fixed to the end of the lead screw near the first bevel gear.

[0010] Furthermore, the pressing assembly includes an outer casing, a pressing chamber, a discharge door, and a drain hole. The pressing chamber is provided inside the outer casing, and the discharge door is hinged to the side of the outer casing away from the feeding assembly. Drain holes are evenly provided at the bottom of the outer casing. A pressing structure is provided at the top of the pressing chamber, and a waste liquid collection structure is provided at the bottom of the outer casing.

[0011] Furthermore, the waste liquid collection structure includes a first collection box, a discharge pipe, a connecting pipe, and a second collection box. The first collection box is located below the outer box, and a discharge pipe is fixed to one side of the bottom of the first collection box. The second collection box is located below the feeding assembly, and a connecting pipe is fixed to one end of the second collection box near the first collection box.

[0012] Furthermore, one end of the connecting pipe extends into the interior of the first collection box.

[0013] Furthermore, the feeding assembly includes a feeding box, a feeding pipe, and separation holes. The feeding box is fixed to one side of the bottom of the outer box, the feeding pipe is fixed to the top of the feeding box, and separation holes are evenly distributed at the bottom of the feeding box.

[0014] Furthermore, the first bevel gear and the second bevel gear are meshed together, and the threaded sleeve and the feed box are slidably connected.

[0015] Furthermore, the pressing structure includes a mounting frame, a hydraulic rod, a connecting rod, and a pressure plate. The mounting frame is fixed to the top of the outer casing. A hydraulic rod is fixed to the inner wall of the top of the mounting frame. A connecting rod is fixed to the bottom end of the hydraulic rod. The bottom end of the connecting rod extends to the top of the pressing chamber and is fixed to the pressure plate.

[0016] Furthermore, the bottom of the hydraulic rod and the top of the outer casing are slidably connected.

[0017] The solid waste pressing device for a front-mounted grid provided by this utility model has the following advantages:

[0018] By setting up a pushing structure and connecting to an external power supply, the screw is driven to rotate by a servo motor, pushing the push plate to evenly feed the solid waste intercepted by the grid into the pressing chamber, avoiding manual intervention. The push plate fits tightly against the inner wall of the feed box to prevent fibrous solid waste from sticking and remaining. The threaded engagement between the screw and the threaded sleeve can adjust the pushing speed to adapt to solid waste with different moisture contents. This device has the function of easy pushing and improves the working efficiency of the solid waste pressing device with front grid during use.

[0019] By setting up a pressing structure, the hydraulic rod drives the pressing plate to apply vertical pressure to the solid waste, which significantly reduces the moisture content. The pressing plate can adjust the pressing height through the hydraulic rod to adapt to the compression characteristics of various solid waste materials. This realizes that the device has the function of easily pressing solid waste and improves the working efficiency of the solid waste pressing device of the front grid during use.

[0020] By incorporating a waste liquid collection structure, a small amount of liquid from the solid waste can be discharged into the second collection box during feeding via a separation hole. During pressing, the liquid can be discharged into the first collection box through a drain hole. With the connection of the connecting pipe, the liquid inside the second collection box can be discharged into the first collection box for collection and then discharged outward through the discharge pipe. This device achieves the function of convenient waste liquid collection and improves the ease of use of the front-grate solid waste pressing device. Attached Figure Description
