Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to an integrated device for treating rosin wastewater. Background Technique

[0002] Rosin wastewater refers to the wastewater generated during the production and use of rosin. Rosin is a resin extracted from pine trees and is widely used in the manufacture of adhesives, coatings, printing inks, and other chemicals. During the production of rosin and its related products, wastewater containing various organic substances and pollutants will be generated.

[0003] Among them, the pretreatment filtration of wastewater is usually the primary step in the treatment of rosin wastewater. In this process, the common operation method is mesh plate filtration, which can separate most solid wastes from the wastewater. In this case, if the mesh holes are too small, it is easy to cause excessive accumulation of solid wastes, resulting in blockage. If the mesh holes are too large, the wastes cannot be filtered efficiently. And using an inclined filter screen for filtration, although it can ensure that the wastes fall from the filter screen under the action of gravity, the inclined filter screen may also cause the wastewater to overflow along the flow. Therefore, it is necessary to design a pretreatment filtration device that can filter rosin wastewater efficiently and will not be blocked. Content of the Utility Model

[0004] The purpose of the utility model is to provide an integrated device for treating rosin wastewater to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: It includes a filtration tank. An upper diversion hopper is fixed inside the upper opening of the filtration tank. A pair of inner support plates are fixed inside the filtration tank. A mesh plate is installed between the inner support plates. A base is fixed at the middle position of the bottom of the filtration tank. A centrifugal sieve cylinder is rotatably connected to the upper end of the base. Drainage ports are opened at both bottom sides of the filtration tank. A drainage port is opened at the bottom rear side of the filtration tank. The mesh plate is composed of symmetric combined mesh frames. The ends of the combined mesh frames close to each other are rotatably connected through a connecting rotating shaft. The bottom sides of the combined mesh frames far from each other are in contact with the upper ends of the inner support plates.

[0006] Preferably, a rotating sleeve is rotatably connected to the connecting rotating shaft. An installation plate is fixed at the middle position of the upper end of the filtration tank. A driving box is fixed on the installation plate. A winch is fixed on the driving box. A lifting rope is fixed on the rotating sleeve. The upper end of the lifting rope is wound around the winch.

[0007] Preferably, a limiting plate is fixed on the lifting rope. A limiting pulling rope is fixed between the ends of the combined mesh frames far from each other and the inner support plates.

[0008] Preferably, the lifting rope extends downward and a counterweight block is fixed at the bottom.

[0009] Preferably, a lower diversion hopper is fixed between the inner support plates and above the centrifugal sieve cylinder.

[0010] Preferably, a drive motor is fixed inside the base, and the output end of the drive motor is fixed to the bottom of the centrifugal sieve cylinder.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The primary filtration of the mesh plate and the secondary filtration of the centrifugal sieve cylinder are utilized to achieve a multiple filtration effect for wastewater foreign matters, reducing the risk of blockage of the filtration structure.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4, the present utility model provides a technical solution: including a filter box 1, an upper diversion hopper 11 is fixed inside the upper opening of the filter box 1, a pair of inner support plates 12 are fixed inside the filter box 1, a mesh plate 2 is installed between the inner support plates 12, a base 4 is fixed at the middle position of the bottom of the filter box 1, a centrifugal sieve cylinder 5 is rotatably connected to the upper end of the base 4, sewage discharge ports 14 are opened at the bottom of both sides of the filter box 1, a drainage port 15 is opened at the bottom of the rear side of the filter box 1, the mesh plate 2 is composed of symmetric combined mesh frames 21, one end of the combined mesh frames 21 close to each other is rotatably connected through a connecting rotating shaft 22, and the bottom of the side of the combined mesh frames 21 away from each other contacts the upper end of the inner support plate 12.

[0019] A rotating sleeve 23 is rotatably connected to the connecting rotating shaft 22, an installation plate 3 is fixed at the middle position of the upper end of the filter box 1, a driving box 31 is fixed on the installation plate 3, a winch is fixed on the driving box 31, a lifting rope 32 is fixed on the rotating sleeve 23, the upper end of the lifting rope 32 is wound around the winch, a limiting plate 34 is fixed on the lifting rope 32, a limiting pull rope 6 is fixed between the end of the combined mesh frame 21 away from each other and the inner support plate 12, the lifting rope 32 extends downward, and a counterweight 33 is fixed at the bottom.

[0020] A lower diversion hopper 13 is fixed between the inner support plates 12 and above the centrifugal sieve cylinder 5, the bottom of the lower diversion hopper 13 is rotatably connected to the upper end of the centrifugal sieve cylinder 5, inner partition plates 51 are equidistantly fixed inside the centrifugal sieve cylinder 5, a driving motor 41 is fixed inside the base 4, and the output end of the driving motor 41 is fixed to the bottom of the centrifugal sieve cylinder 5.

[0021] Working principle: First, connect the whole device to an external power supply. Under the gravity pull of the counterweight 33 at the bottom, the connecting rotating shaft 22 will move downward, causing the connection part of the combined mesh frames 21 to move downward, and then making the mesh plate 2 form a V-shaped structure with the opening upward. At this time, waste enters the filter box 1 and, through the diversion of the upper diversion hopper 11, enters the mesh plate 2, where some large solid waste can be filtered. And due to the V-shaped mesh plate 2 with the opening upward, it can prevent sewage from overflowing to both sides, causing the waste to accumulate in the middle of the mesh plate 2. When the waste needs to be processed, the winch in the driving box 31 can be used to pull the lifting rope 32 to wind it up, so that the connecting rotating shaft 22 moves upward, making the mesh plate 2 form a V-shaped structure with the opening downward, and the waste will be discharged along the inclined combined mesh frames 21 on both sides and finally discharged from the sewage discharge port 14, achieving the purpose of automatic waste cleaning without waste being mixed with wastewater and discharged. After the sewage enters the centrifugal sieve cylinder 5 through the lower diversion hopper 13, the driving motor 41 can be used to drive the centrifugal sieve cylinder 5 to rotate. Under the action of centrifugal force, the sewage is quickly thrown out, and the smaller solid waste is retained in the centrifugal sieve cylinder 5, while the sewage is discharged from the drainage port 15, achieving the purpose of multiple filtration and reducing the risk of blockage of the filtration structure during the integrated pretreatment of rosin wastewater.
