Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment, in particular to a slag discharging baffle of a rotary mechanical grille sewage cleaner. Background Art
[0002] A rotary mechanical grille sewage cleaner is a device that can continuously and automatically remove relatively large floating and suspended substances in a fluid for the purpose of solid-liquid separation. It is widely used in the front-end pretreatment system of sewage treatment. It is used to remove relatively large floating and suspended substances that may block pump units and pipeline valves, and ensure the normal operation of subsequent treatment facilities. When water flows through the grille sewage cleaner, floating substances, suspended substances and sediment (such as plastic bags, branches, grass-like substances and fibrous garbage) mixed in the water body are effectively intercepted, and only water and garbage smaller than the gap between the grille bars can pass through, thereby reducing the load of subsequent treatment processes and improving the working environment of subsequent equipment.
[0003] In actual use, the rotary mechanical grille sewage cleaner operates from bottom to top on the water-facing side through a tooth rake, bringing the intercepted slag to the water surface. Then, during the process of the tooth rake rotating from top to bottom, these slag freely fall into the slag collection hopper of the slag conveyor. During the process of the tooth rake turning from top to bottom, some solid pollutants will fall on the ground due to reasons such as wind blowing and adhesion during the gravity fall, and part of the pollutants cannot fall into the slag collection tank, resulting in incomplete collection of slag materials and affecting the environmental hygiene of the grille room. The slag that fails to fall immediately will fall into the water body behind the grille sewage cleaner along with the movement of the tooth rake. At the same time, some sundries wrapped around the tooth rake cannot fall off in time and are brought back into the water body behind the grille sewage cleaner by the tooth rake. Even some sundries will continuously wrap around the tooth rake and affect the normal operation of the tooth rake as the tooth rake keeps rotating.
[0004] Therefore, there is an urgent need for a technical solution that can improve the existing equipment, increase the slag collection rate, and ensure the efficient operation of the sewage treatment system. Summary of the Utility Model
[0005] The purpose of the utility model is to solve the deficiencies of the existing technology and provide a slag discharging baffle of a rotary mechanical grille sewage cleaner to increase the slag collection rate and ensure the efficient operation of the sewage treatment system.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0025] A slag discharging baffle of a rotary mechanical grille sewage cleaner disclosed by the utility model is used in the scenario of intercepting and guiding the dirt between the rake teeth to improve the collection efficiency of the slag collection tank 7.
[0026] Refer to Figure 1 , a slag discharging baffle of a rotary mechanical grille sewage cleaner, including a fixed seat 1 welded to the slag outlet frame 6 of the rotary mechanical grille sewage cleaner, a leveling seat 2 bolted to the fixed seat 1, a connecting rod 3 sleeved with the leveling seat 2, a plurality of guide teeth 4 welded above the connecting rod 3, and a guide plate 5 welded below the connecting rod 3. The fixed seats 1 are in two groups, respectively welded at both ends of the slag outlet of the rotary mechanical grille sewage cleaner. The number of leveling seats 2 is the same as that of the fixed seats 1. A plurality of leveling gaskets 81 are padded between the leveling seat 2 and the fixed seat 1. Both ends of the connecting rod 3 are connected to the two groups of leveling seats 2 respectively. In order to prevent the guide teeth 4 from interfering with the rake teeth, as Figure 5 shown, the guide teeth 4 are parallel to the rake teeth of the rotary mechanical grille sewage cleaner, and the guide teeth 4 are evenly arranged between the rake teeth. As Figure 6 shown, the bottom end of the guide plate 5 is located above the slag collection tank 7. The fixed seat 1 is made of steel plate. The guide plate 5 and the slag collection tank 7 have a lap width of not less than 1 cm. The spatial position of the connecting rod 3 can be adjusted through the leveling gasket 81, the leveling seat 2 and the fixed seat 1, thereby reducing the installation requirements for the fixed seat 1 and enabling the guide teeth 4 to be placed between the rake teeth even when the angle between the fixed seat 1 and the rake teeth is too large, preventing the rake teeth from colliding with the guide teeth 4.
[0027] Specifically, as Figure 3 shown, the fixed seat 1 is provided with a retaining groove 11. The retaining groove 11 is a cylindrical hole. The connecting rod 3 passes through the retaining groove 11 and is sleeved with the fixed seat 1. The aperture of the retaining groove 11 is larger than the outer diameter of the connecting rod 3. At least four leveling holes 12 are arranged in an equidistant annular array along the center of the retaining groove 11 outside the retaining groove 11.
[0028] As Figure 2 and Figure 4 shown, in order to facilitate installation and prevent the leveling seat 2 from interfering with the rake teeth, the leveling seat 2 is fixed to the outside of the fixed seat 1 through a leveling bolt 8. As Figure 3As shown in the figure, a boss 21 is integrally provided on the side of the leveling base 2 away from the fixed base 1. A limiting groove 22 penetrating through the leveling base 2 is provided on the side of the leveling base 2 close to the fixed base 1. The limiting groove 22 is a cylindrical hole. The limiting groove 22 is coaxial with the retaining groove 11. The limiting groove 22 is in interference fit with the connecting rod 3. At least four leveling fitting holes 23 are provided around the limiting groove 22 in an equally spaced annular array along the center of the limiting groove 22. The leveling fitting holes 23 correspond to the leveling holes 12, and specifically, the quantity, aperture, and orientation all correspond. Both ends of the connecting rod 3 pass through the retaining groove 11 and are inserted into the limiting groove 22. In order to prevent the connecting rod 3 from displacing or rotating relative to the leveling base 2, a through first limiting hole 24 is provided on the outer side of the boss 21. Second limiting holes 31 are provided at both ends of the connecting rod 3. The aperture of the first limiting hole 24 corresponds to that of the second limiting hole 31. A limiting bolt 9 passes through the first limiting hole 24 and the second limiting hole 31, and the first limiting hole 24 and the second limiting hole 31 are kept concentric by the limiting bolt 9.
[0029] Specifically, as Figure 4 shown in the figure, the fixed base 1 and the leveling base 2 are connected by a plurality of leveling bolts 8. The leveling bolts 8 pass through the leveling fitting holes 23 and the leveling holes 12. A leveling gasket 81 is provided between each leveling fitting hole 23 and the leveling hole 12. The leveling gasket 81 is sleeved on the leveling bolt 8. By setting leveling gaskets 81 with different thicknesses, the parallelism between the leveling base 2 and the rake teeth is controlled. The leveling base 2 is sleeved with the connecting rod 3 through the limiting groove 22, so as to control the angle between the connecting rod 3 and the rake teeth, and thus control the parallelism between the guide teeth 4 and the rake teeth as Figure 5 shown in the figure, preventing the guide teeth 4 from colliding with the rake teeth and affecting the working efficiency of the rotary grille cleaner.
[0030] In order to better intercept the solid dirt between the rake teeth, the guide teeth 4 are bent, specifically as Figure 1 shown, the top of the guide teeth 4 is bent in the reverse direction of the movement direction of the rake teeth.
[0031] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. The substitution can be the substitution of part of the structure, device, and method steps, or the substitution of the complete technical solution. Any equivalent substitution or change made according to the technical solution of the present invention and its inventive concept should be covered within the protection scope of the present invention.
