Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to sludge treatment equipment with strong environmental protection. Background Art

[0002] With the continuous development and progress of today's society and the increasing number of human factories, it is often easy to see the generation of a large amount of sludge, which contains a large amount of water, soil and other impurities. Sludge is the inevitable product of sewage treatment plants and submersible treatment. If untreated sludge is discharged into the environment, it will cause serious damage, bring secondary pollution to water bodies and the atmosphere, and have serious consequences for the ecological environment and human activities.

[0003] As disclosed in Chinese patent announcement number CN219384982U, an energy-saving and environmentally friendly sludge treatment equipment is used. When in use, the sludge enters the box from the feed port, and the sludge is screened through three filter layers, so that sludge of different volumes is located above different filter layers, and the water in the sludge is discharged through the water outlet after passing through the filter layer, and then the electric telescopic rod is started, driving the baffle plate to pass through the horizontal hole into the box to block the bottom of the two filter layers above and the inner surface of the box. Then when the two-way cylinder starts to shrink to the middle, it drives the three-section turning rod to move to the middle, thereby driving the plane plate to move closer to the box, and the plane plate drives the push rod and the pressure plate to move to the opposite side, and the triangular bar better shovels the sludge on the surface of the filter layer, so that the sludge on the surface of the filter layer is gradually moved closer and compressed into blocks under the relative movement of the pressure plates on both sides. Finally, the output end of the two-way cylinder moves to both sides, so that the pressure plates are away from each other, and then the flip door is opened to take out the sludge blocks on the filter layer to complete the operation.

[0004] However, the energy-saving and environmentally friendly sludge treatment equipment in the above application relies on the natural sedimentation of sludge to separate the sewage inside it, which is relatively inefficient. In addition, when the sludge contains water, it is viscous and may clog the filter holes on the filter layer, thereby affecting the seepage of sewage. Therefore, it has certain limitations.

[0005] For this reason, we urgently need to provide a sludge treatment equipment with strong environmental protection. Utility Model Content

[0006] The purpose of the utility model is to provide an environmentally friendly sludge treatment equipment to solve the problem that the energy-saving and environmentally friendly sludge treatment equipment proposed in the above-mentioned background technology relies on the natural sedimentation of the sludge to separate the sewage inside it, which is relatively inefficient, and the sludge is viscous when containing water, which may clog the filter holes on the filter layer, thereby affecting the problem of sewage seepage.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an environmentally friendly sludge treatment equipment, including a treatment box and supporting legs, wherein the four supporting legs are respectively fixedly connected to the four corners of the bottom of the treatment box, and a filter press device and a treatment device are arranged inside the treatment box.

[0008] The filter press device comprises an extrusion unit, a discharge unit and a blockage clearing unit.

[0011] A further improvement is that slide grooves are respectively provided on the front and rear side surfaces of the processing box, and the electric slide is slidably connected to the inside of the slide groove. When the moisture in the sludge is squeezed out, the electric slide is driven to slide to the right along the electric guide rail and the inner wall of the slide groove, thereby driving the discharge scraper to slide to the right. At the same time, the electric sealing valve is opened to discharge the sludge through the discharge pipe for recycling.

When the electromagnet is energized, suction is generated between the electromagnet and the magnetic slide bar, thereby pulling the magnetic slide bar to slide upward along the sleeve and driving the clearing plate to move upward, so that the sludge inside the filter hole on the filter plate is lifted and discharged through the clearing plate to avoid clogging of the filter plate and affecting the solid-liquid separation of the sludge.

[0014] A further improvement is that the treatment device includes a stirring motor, a sealed bearing, a stirring shaft, and a stirring rod. The stirring motor is installed at the bottom center of the treatment box, the sealed bearing is installed inside the bottom center of the treatment box, the stirring shaft is connected to the output end of the stirring motor, and is rotatably connected to the inside of the sealed bearing, and its top extends into the inside of the treatment box.
