Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment equipment for preparing water-based paint, and in particular to wastewater treatment equipment for preparing water-based paint. Background Art

[0002] Paint production wastewater refers to the water discharged during the production of resins, varnishes, and color paints. Paint wastewater mainly comes from the large number of equipment that needs to be washed during paint production, such as paint mixing tanks, filters and filter media, storage tanks, and storage tanks. Especially in the production of water-based paints, equipment cleaning is more frequent. The pollutant composition of water-based paints is complex and the pollutant content is high. Based on environmental protection requirements, the wastewater and sewage generated during the paint production process need to be treated before discharge.

[0003] There are three methods for treating water-based paint wastewater: physical treatment, chemical treatment and biological treatment. When using the chemical treatment method to treat wastewater, it is usually necessary to use mixing equipment to fully mix and stir the wastewater with chemical reagents. After long-term use of the mixing equipment, the stirring blades will inevitably be damaged by rust, wear and corrosion by sewage. This damage has a great impact on the stirring function of the stirring blades, thereby affecting the effect of sewage treatment. The stirring blades are usually welded to an annular structure or the stirring blades and the annular structure are processed as an integrated structure. Manual repair of the stirring blades requires replacement of the entire stirring blade and the annular structure, which not only causes waste of resources and increases the company's cost expenditure, but also the replacement process is difficult, time-consuming and labor-intensive.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention provides a fixing device, a limiting device, a rotating roller, a mounting shell, an extension shaft and other structures. When the stirring blade is damaged by rust, wear and sewage corrosion and needs to be repaired, the limiting of the mounting shell is first released to drive the stirring blade to move out of the processing shell, and the limiting of the stirring blade is released by the lower pressure shaft, so that it can be easily removed and replaced with a new stirring blade or some surface treatment is performed.

[0016] 3. The present invention provides structures such as positioning rods and positioning holes to extend the position where the shaft stops rotating. Three positioning rods can be inserted into the positioning holes, so that the position where the extension shaft stops rotating can be accurately ensured to be the maintenance stop position we need.

[0031] The fixing device includes two groups of fixing blocks 22, each group has two, a sliding gap 23 is set in the middle of the same group of fixing blocks 22, the fixing blocks 22 are fixedly connected to the inner wall of the mounting shell 10, the top and bottom surfaces of the stirring blade 11 are respectively in contact with the two groups of fixing blocks 22, a moving plate 24 is slidably connected to the inner wall of the sliding gap 23, four special-shaped holes penetrating the moving plate 24 are provided on the side of the moving plate 24, the special-shaped holes are composed of a first hole 25 and a second hole 26, and the two end surfaces of the moving plate 24 are respectively fixedly connected to the gas spring 2 7 and L-shaped plate 28, the gas spring 27 is fixedly connected to the inner wall of the mounting shell 10, the inner wall of the first hole 25 is slidably connected with a first cylinder 29, the first cylinder 29 is fixedly connected to the side of the stirring blade 11, the end of the first cylinder 29 is fixedly connected with a second cylinder 30, the second cylinder 30 is slightly smaller than the diameter of the second hole 26, the width of the intersection of the first hole 25 and the second hole 26 is slightly smaller than the diameter of the first cylinder 29, and the surface of the extension shaft 12 is fixedly connected with three lower pressing shafts 31, and the lower pressing shafts 31 are adapted to the L-shaped plate 28;

[0032] The limiting device includes a limiting rod 32, which penetrates the mounting shell 10 and is slidably connected to the mounting shell 10. The surface of the limiting rod 32 is slidably connected to the third plate 33, the bottom of the third plate 33 is fixedly connected to the fourth plate 34, the fourth plate 34 and the surface of the rotating roller 7 are fixedly connected, the end of the limiting rod 32 is fixedly connected to the L-shaped connecting plate 35, the surface of the limiting rod 32 is sleeved with a limiting spring 36 whose two ends are respectively fixed on the third plate 33 and the L-shaped connecting plate 35, the side of the L-shaped connecting plate 35 is fixedly connected to the pressure plate 37, the side of the pressure plate 37 is provided with an inclined surface, and the inclined surface is adapted to the touch plate 16;

[0033] During operation, when the stirring blade 11 is damaged by rust, wear, sewage corrosion, etc. and needs to be repaired, the motor is stopped, the extension shaft 12 is rotated to a suitable angle to ensure that the stirring blade 11 can be repaired smoothly, and the hand wheel 21 is manually rotated. The rotating hand wheel 21 drives the rotating wheel 18 to rotate through the first shaft 19, and the rope 17 will be wound around the rotating wheel 18. The L-shaped pulling block 14 at the end of the rope 17 will move upward along the T-shaped slide groove 13 under the pull of the rope 17. The L-shaped pulling block 14 drives the touch plate 16 to move through the first plate 15. The movement of the touch plate 16 will gradually contact and squeeze the inclined surface of the pressure plate 37. The pressed plate 37 The pressure plate 37 moves backward and drives the limiting rod 32 to move backward through the L-shaped connecting plate 35. At the same time, the limiting spring 36 is stretched, and the limiting rod 32 moving backward finally releases the limit on the mounting shell 10. When the mounting shell 10 releases the limit, the top surface of the touch plate 16 just contacts the inner wall of the mounting shell 10. As the L-shaped pulling block 14 continues to move upward, the touch plate 16 will drive the mounting shell 10 to move upward, and the device inside the mounting shell 10 is also synchronously driven to move upward. As the mounting shell 10 moves, the L-shaped plate 28 will contact the lower pressing shaft 31 and be squeezed by the lower pressing shaft 31. The squeezed L-shaped plate 28 will drive the moving plate 24 to move. The movable plate 24 moves downward and squeezes the gas spring 27. When the movable plate 24 moves, the stirring blade 11 is restricted from moving up and down by the fixed block 22. Therefore, the first cylinder 29 will enter the second hole 26 from the first hole 25. The diameter of the second hole 26 is slightly larger than that of the second cylinder 30. The second cylinder 30 can pass through the second hole 26. The width of the intersection of the first hole 25 and the second hole 26 is slightly smaller than the diameter of the first cylinder 29. Therefore, the first cylinder 29 needs to overcome a certain resistance to enter the second hole 26. When the second cylinder 30 can pass through the second hole 26, the rotation of the rotating hand wheel 21 is stopped, the rope 17 is no longer wound, and the rotating hand wheel 21 is fixed to the column There are many ways to fix it, which will not be repeated here. At this time, the stirring blade 11 has been moved out of the processing shell 1, and it can be easily removed to replace it with a new stirring blade 11 or perform some surface treatment. The whole process can be operated by one person, which is simple and quick. Since the stirring blade 11 is set as a separate structure instead of three stirring blades 11 welded together by a ring structure, the weight of a separate stirring blade 11 is small and can be replaced by one person, making it easy to replace the stirring blade 11. After the replacement is completed, the entire device can be reset. Since it is a sewage treatment, some structures in the device that come into contact with the sewage also need regular maintenance to prevent corrosion by sewage.

[0034] As a further solution of the present invention, three brackets 38 are fixedly connected to the top of the cover plate 4, and the ends of the three brackets 38 are commonly fixedly connected to a bracket ring 39. The inner wall of the bracket ring 39 is rotatably connected to a bracket shaft 40, and the bracket shaft 40 is fixedly connected to the top of the extension shaft 12; when working, by setting structures such as the bracket 38, the bracket ring 39 and the bracket shaft 40, it is ensured that the motor drives the extension shaft 12 to rotate, and since the end is not fixed, the extension shaft 12 will shake, causing damage to the equipment will not occur.

[0035] As a further solution of the present invention, a positioning block 41 is fixedly connected to the top surface of the bracket 38, and a positioning rod 42 that penetrates the positioning block 41 is slidably connected to the side of the positioning block 41. Three positioning holes 43 are opened on the side of the bracket shaft 40, and the positioning rod 42 and the positioning hole 43 are slidably connected; during operation, in order to ensure that the position where the extension shaft 12 stops rotating manually is the maintenance stop position we need, by setting structures such as the positioning rod 42 and the positioning hole 43, the position where the extension shaft 12 stops rotating, the three positioning rods 42 can be inserted into the positioning holes 43, so that it can accurately ensure that the position where the extension shaft 12 stops rotating is the maintenance stop position we need.

[0036] As a further solution of the present invention, four groups of special-shaped grooves 44 are provided on the side of the movable plate 24, each group having two special-shaped grooves, and the special-shaped grooves 44 in the same group are distributed on both sides of the intersection of the first hole 25 and the second hole 26; when working, the width of the intersection of the first hole 25 and the second hole 26 is slightly smaller than the diameter of the first cylinder 29, so the first cylinder 29 needs to overcome a certain resistance before entering the second hole 26. In order to avoid the problem of excessive resistance encountered by the first cylinder 29, special-shaped grooves 44 are provided on both sides of the intersection of the first hole 25 and the second hole 26. When the first cylinder 29 moves to the intersection of the first hole 25 and the second hole 26, it will squeeze the inner wall here. Due to the existence of the special-shaped grooves 44, the structure here will be deformed, so that the width of the first cylinder 29 passing through here is increased, thereby reducing its forward resistance.

[0037] As a further solution of the present invention, a counterweight ring 45 is slidably connected to the surface of the extension shaft 12, and the inner wall of the counterweight ring 45 is fixedly connected to the L-shaped pulling block 14; during operation, the counterweight ring 45 is provided to prevent the L-shaped pulling block 14 from shaking up and down easily, thereby ensuring its stability.
