Description

Technical Field

[0001] This utility model relates to the technical field of gravity removal reactor equipment, specifically a gravity removal primary reactor device. Background Technology

[0002] With the acceleration of industrialization and urbanization, the demand for wastewater treatment is becoming increasingly urgent, and traditional methods face challenges such as low efficiency and high energy consumption. The development of new materials, automated control, and membrane separation technology has provided new opportunities for wastewater treatment technology. Grain removal primary reactors have emerged as a result, becoming important equipment in the wastewater treatment field due to their high efficiency in gravity removal, energy saving, environmental protection, and strong adaptability. Through specific reaction conditions and process design, this reactor can efficiently remove pollutants such as heavy metal ions, suspended solids, and organic matter from wastewater, improving the wastewater treatment effect and meeting increasingly stringent environmental standards and market demands. The design of a gravity removal primary reactor is relatively complex, containing multiple reaction units and a control system, requiring specialized technicians to enter from the reactor top inlet for operation and maintenance. This increases the difficulty and cost of equipment management, and also places higher demands on the professional skills of operators, increasing the maintenance cost of the device. Therefore, we propose a gravity removal primary reactor device. Utility Model Content

[0005] In the above scheme, the cover is installed on top of the reactor body by screws.

[0006] In the above scheme, the diameter of the manhole is 600mm.

[0007] In the above scheme, the motor is mounted on the bracket, and the output end of the motor is connected to the rotating shaft via a coupling.

[0008] In the above scheme, the connecting assembly includes a connector sleeved on the rotating shaft, the connector being fixed to the side of the rotating shaft by a second bolt, and the stirring paddle being fixed to the end of the connector by a first bolt.

[0009] In the above scheme, the side pipe and the top pipe are both seamless steel pipes of different diameters.

[0010] In the above scheme, a filter screen is installed inside the reactor body.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This degravimetric primary reactor device has a simple and reasonable structural design and strong practicality. The manhole at the bottom side of the reactor body allows for convenient inspection of the internal equipment status, enabling timely detection and handling of potential problems. Simultaneously, maintenance work can be carried out through the manhole when necessary, reducing downtime and improving production efficiency. The manhole design at the bottom side helps reduce the difficulty of cleaning the reactor interior. After the reaction, the reactor interior can be thoroughly cleaned through the manhole, preventing residues from affecting subsequent reactions. The bottom side manhole significantly reduces the risk of professional operators working at heights, ensuring safety. Furthermore, the stirring mechanism installed inside the reactor body accelerates the decomposition process of materials within the liquid, improving the degravimetric effect.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides a technical solution: a primary reactor device for degravity removal, comprising a reactor body 1, a cover 11 on the top of the reactor body 1, the reactor body 1 being mounted on a base 12, a slag outlet 13 on the side of the reactor body 1 near the bottom, a manhole 14 on the side of the slag outlet 13, multiple side pipes 15 on the side of the reactor body 1, multiple top pipes 16 above the cover 11, a motor 17 in the middle of the cover 11, a rotating shaft 19 connected to the bottom end of the motor 17, and a stirring paddle 2 mounted on the rotating shaft 19 via a connecting assembly.

[0019] Specifically, the motor 17 is a reversible motor, and it is connected to the power supply and switch through wires. When working, the motor 17 drives the rotating shaft 19 to rotate, thereby stirring the inside of the reactor body 1 through the stirring paddle 2, so that the material can be effectively separated, which is convenient for subsequent degravity treatment.

[0020] In the above scheme, the cover 11 is installed on top of the reactor body 1 by screws. The cover 11 is separate from the reactor body 1, thereby facilitating the maintenance of the above mechanism.

[0021] In the above scheme, the diameter of the manhole 14 is 600mm.

[0022] In the above scheme, the motor 17 is mounted on the bracket 18, and the output end of the motor 17 is connected to the rotating shaft 19 through a coupling.

[0023] In the above scheme, the connecting assembly includes a connector 22 sleeved on the rotating shaft 19. The connector 22 is fixed to the side of the rotating shaft 19 by a second bolt 23, and the stirring paddle 2 is fixed to the end of the connector 22 by a first bolt 21. The use of this detachable connecting mechanism facilitates disassembly, thereby enabling convenient replacement and cleaning of the equipment and reducing operating costs.

[0024] In the above scheme, the side pipe 15 and the top pipe 16 are both seamless steel pipes of different diameters.

[0025] In the above scheme, a filter screen 24 is provided inside the reactor body 1. The filter screen 24 can filter impurities inside the liquid.

[0026] Working principle:

[0027] This type of gravity removal primary reactor device uses Q235-B material, has a diameter of 2800mm, and a height of 5700mm. It has a flush-type sludge outlet (762mm long, 496mm high) at the bottom side, two seamless pipes (one 89mm diameter, the other 219mm diameter) made of No. 20 steel, and a manhole 14 (600mm diameter) located on the side near the ground (next to the sludge outlet 13). Wastewater first passes through a physical device such as a screen or grate to remove larger suspended solids and particulate matter, serving as preliminary purification before entering the reactor. Inside the reactor, gravity causes suspended solids in the wastewater to settle naturally to the bottom, forming sludge. This process is the core of gravity removal, removing heavy pollutants from the wastewater through physical separation. After settling, the relatively clear wastewater flows out from the top of the reactor body 1 and enters the subsequent wastewater treatment unit or is directly discharged. The sludge accumulated at the bottom needs to be cleaned regularly. The manhole 14 at the bottom facilitates equipment maintenance, reduces the risk of professional operators working at heights, and facilitates cleaning when there is a lot of sludge. It can also ensure the normal operation of production, which is very conducive to its promotion and implementation.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
