Description

Technical Field

[0001] The present invention relates to the technical field of adhesive wastewater treatment, and in particular to a wastewater treatment device for environmentally friendly adhesive production. Background Art

[0002] With increasingly stringent environmental regulations and growing demand for green industrial production, wastewater treatment technology generated during the production of environmentally friendly adhesives has become a key constraint to the industry's sustainable development. This wastewater typically contains complex components such as high molecular weight polymers, organic solvents, and chemical additives. It has high chemical oxygen demand (COD), is difficult to degrade, and has potential biotoxicity. Improper treatment can cause serious harm to the ecological environment.

[0003] Existing wastewater treatment devices have the following technical bottlenecks in the reagent mixing and solid-liquid separation stages:

[0004] 1. Low mixing efficiency: Traditional mixing devices mostly use a unidirectional rotating structure. The mixing of reagents and wastewater relies on shear force in a single direction, resulting in uneven dispersion of the reagents and prolonged reaction time, making it difficult to meet the requirements of efficient treatment. Especially when treating high-viscosity adhesive wastewater, unidirectional stirring easily forms laminar flow areas, further reducing mixing efficiency.

[0005] 2. The filtration system is prone to clogging: Conventional filtration devices mostly use a flat filter screen structure. The filter residue is easy to accumulate on the filter screen surface to form a filter cake, causing the filtration resistance to rise sharply, requiring frequent shutdowns for cleaning, and affecting the continuity of treatment.

[0006] In view of the above technical difficulties, it is necessary to design an environmentally friendly wastewater treatment device for adhesive production. Summary of the Invention

[0010] As a further improvement of the present invention, the mixing mechanism includes a first rotating drum vertically penetrating the upper end of the first cover plate, and the first rotating drum is rotatably connected to the first cover plate, a rotating tube is inserted into the interior of the first rotating drum, and the rotating tube is rotatably connected to the first rotating drum, the first rotating drum is located on the side wall of the mixing box and has two L-shaped rods fixed thereon, a stirring rod is fixed on the side wall of the L-shaped rod, and the rotating tube is located on the side wall of the mixing box and is connected to a discharge inclined tube.

[0011] As a further improvement of the present invention, the first driving mechanism includes a mounting bracket fixedly connected to the upper end of the first cover plate, the upper end of the rotating tube passes through the mounting bracket, and the rotating tube is rotatably connected to the mounting bracket, a first motor is installed on the side wall of the mounting bracket, the output shaft of the first motor is fixedly connected to the second gear, a first gear is fixedly sleeved on the side wall of the first rotating drum, and a third gear is fixedly sleeved on the side wall of the rotating tube, and the third gear and the first gear are respectively engaged with the upper and lower sides of the second gear.

[0012] As a further improvement of the present invention, the feeding mechanism includes a dosing hopper, the lower end of which is connected to the upper end of the rotating tube through a first rotary joint, and a support ring is mounted on the outer wall of the dosing hopper. The lower end of the support ring is fixedly connected to two fixing rods, and the lower end of the fixing rod is fixedly connected to the upper end of the mounting frame.

[0013] As a further improvement of the present invention, the filtering mechanism includes a second rotating drum vertically penetrating the upper end of the second cover plate, the second rotating drum is rotatably connected to the second cover plate, the lower end of the second rotating drum is fixedly connected to a connecting sleeve, the lower end of the connecting sleeve is threadedly sleeved with a filter screen frame, and the filter screen frame is a conical structure.

[0014] As a further improvement of the present invention, the second driving mechanism includes a second motor installed on the upper end of the second cover plate, the output shaft of the second motor is fixedly connected to the fifth gear, and a fourth gear is fixedly sleeved on the side wall of the second rotating drum, and the fourth gear is engaged with the fifth gear.

[0015] As a further improvement of the present invention, the conveying mechanism includes a pump installed on the upper end of the second cover plate, the input end of the pump is connected to a first connecting pipe, the end of the first connecting pipe away from the pump is connected to the side wall of the mixing box, the output end of the pump is connected to a second connecting pipe, and the end of the second connecting pipe away from the pump is connected to the upper end of the second rotating drum through a second rotary joint.

[0018] Beneficial effects of the present invention:

[0019] The first motor drives the second gear, which in turn drives the first and third gears to rotate in the opposite direction. This causes the stirring rod of the first rotating drum and the discharging inclined tube of the rotating tube to move in the opposite direction. The dual-axis counter-rotating structure generates a strong shear force, which can quickly disperse the reagents added from the dosing hopper, greatly improving the reaction efficiency between wastewater and reagents in the mixing box.

[0020] The filter frame adopts a conical structure and uses the second motor to drive the fourth gear to drive the second drum to rotate at high speed, so that the mixed liquid entering the connecting sleeve generates radial pressure under the action of centrifugal force, which significantly enhances the ability of the filtrate to pass through the filter frame. At the same time, the conical structure causes the filter residue to gather towards the center to avoid clogging, thereby improving the separation effect of the filter box.

[0021] The threaded filter frame can be easily disassembled and replaced to meet the needs of filtration with different precisions. Combined with the second rotary joint, it allows the second connecting pipe to remain fixed when the second drum rotates, effectively preventing the pipeline from being entangled during transportation.
