Description

A reaction device for a wastewater treatment apparatus Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically a reaction device for wastewater treatment equipment. Background Technology

[0002] Water treatment can also be called wastewater treatment. However, the latter is a broad term and can also refer to industrial wastewater. For most cities, the sewer system also discharges a portion of sewage to wastewater treatment plants, which typically pre-treat the wastewater at the plant itself to reduce pollutant load. If the sewer system is a combined system, it will also carry urban runoff (rainwater) to the wastewater treatment plant. Sewage can flow to the wastewater treatment plant through pipes and with the assistance of gravity and pumps. The wastewater is then treated and purified at the treatment plant. Currently, the commonly used wastewater treatment method is a combination of physical and chemical methods. This often involves feeding wastewater into reaction tanks, adding chemicals for chemical reactions, or electrolysis and other processes, followed by filtration of impurities.

[0003] In reaction tanks, filtration is often achieved by installing drain caps on filter plates. However, filter plates are usually installed inside the reaction tank using brackets. This method results in gaps between the filter plates and the reaction tank, leading to poor sealing and insufficient filtration, which affects the wastewater treatment effect. Furthermore, this method is complicated to install and inconvenient to use. Summary of the Invention

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0029] Example:

[0030] A reaction device for wastewater treatment, as shown in Figures 1-3, includes a reaction tank 1. The reaction tank 1 has a structure in which the inner diameter gradually decreases from top to bottom. Several layers of filter plates 2 are provided inside the reaction tank 1. The connection between the filter plates 2 and the reaction tank 1 is sealed by a sealing ring 13.

[0031] In one possible implementation, a sealing groove is provided on the inner side of the reaction vessel 1, and a sealing ring 13 is fitted into the sealing groove.

[0032] In one possible implementation, the diameter of several filter plates 2 decreases sequentially from top to bottom, and the diameter of the filter plate 2 is adapted to the inner diameter of the reaction vessel 1 at the corresponding position.

[0033] In one possible implementation, the filter plate 2 includes a filter plate body 21, on which a plurality of drainage caps 22 are provided. A counterweight support 23 is provided at the bottom of the filter plate body 21. The counterweight support 23 includes two vertical support rods. The filter plate body 21 is divided into nine regions by the counterweight support 23. A plurality of drainage caps 22 are provided in the nine regions. The drainage caps 22 in the central region are arranged in a rectangular array, and the drainage caps 22 in the eight outer regions are arranged in a ring array.

[0034] In one possible implementation, since the overall mass of the filter plate body 21 is relatively light, if it is placed in the reaction vessel 1 by its own mass, the filter plate body 21 is easily inflated during the impact of the liquid below, resulting in poor sealing. Based on this, the counterweight bracket 23 can provide counterweight for the filter plate 2 to avoid the problem of poor sealing effect due to insufficient mass of the filter plate body 21.

[0035] In one possible implementation, the bottom of the reaction vessel 1 is provided with an electrolysis reaction zone 11, the outer side of the top of the reaction vessel 1 is provided with a drainage weir 12, and the top of the reaction vessel 1 is provided with a cover plate 15.

[0036] In one possible implementation, the reaction vessel 1 is divided into several filter layers in the vertical direction by several layers of filter plates 2, and each filter layer has an inspection port 14 on its outer wall.

[0037] Working principle: Referring to Figures 1-3, during use, several filter plates 2 are placed into the reaction vessel 1 in sequence. When they reach the appropriate position, the filter plates 2 contact the sealing ring 13. Press the filter plates 2 down, at which time the filter plates 2 squeeze the sealing ring 13 and deform the sealing ring 13 until the counterweight support 23 below contacts the side wall of the reaction vessel 1. At this time, the sealing ring 13 and the filter plates 2 are sealed. At the same time, the inspection port 14 on the outside of the reaction vessel 1 can be opened to clean and maintain the inside of the reaction vessel 1.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
