The utility model discloses an overflow groove for a dry quenching furnace, wherein the front section of a groove body is provided with water flow inlets symmetrically arranged on two sides along an axis.

The utility model discloses an overflow groove for a dry quenching furnace, wherein a filter plate is arranged into a conical structure protruding towards the front section of a groove body.

The utility model discloses an overflow groove for a dry quenching furnace, wherein a filter plate is arranged into a three-dimensional net structure, and the surface of the filter plate is attached with active carbon.

The utility model discloses an overflow groove for a dry quenching furnace, wherein a noise reduction device consists of a splitter plate arranged at the tail end of the rear section of a groove body and a pair of guide plates symmetrically arranged at two sides along the axis, the guide plates are fixedly connected with the inner walls at two sides of the groove body, the end parts of the splitter plate and the inner wall at the rear section of the groove body are fixedly arranged into a whole, and the guide plates and the splitter plate are respectively arranged at the front end and the rear end of a water flow outlet.

The utility model discloses an overflow groove for a dry quenching furnace, wherein a guide plate is arranged in the direction of a splitter plate close to the front section of a groove body.

By adopting the technical scheme, on the premise of not changing the flow of overflow water, the dry quenching furnace is sealed by gas, the coke and coke dust taken away are filtered and left in the overflow groove, so that the overflow groove is convenient to clean, the scattered coke and coke dust are convenient to collect, the noise generated by water flow can be reduced in the use process, the environment of a production site is optimized, the labor intensity of workers is reduced, the utilization efficiency of the overflow groove is improved, and the requirements of energy conservation and emission reduction are met.

The utility model will be explained in more detail below with reference to the drawings and examples.

Drawings

The contents of the description and the references in the drawings are briefly described as follows:

FIG. 1 is a schematic diagram of the structure of an isopipe of the present invention;

FIG. 2 is a top view of an isopipe of the present invention.

Labeled as: 1. a trough body; 2. a front section of the trough body; 3. a filter plate; 4. a rear section of the tank body; 5. a water flow inlet; 6. a baffle; 7. a flow distribution plate; 8. and a water outlet.

Detailed Description

The following description of the embodiments of the present invention, with reference to the accompanying drawings, will be made in further detail to explain embodiments of the present invention, such as the shapes, structures, mutual positions and connection relationships of the components, the functions and working principles of the components, the manufacturing process, and the operation and use method, so as to help those skilled in the art to more completely, accurately and deeply understand the concept and technical solutions of the present invention.

Fig. 1 is a schematic structural diagram of an overflow tank of the present invention, and the overflow tank for a dry quenching furnace shown in fig. 1 comprises a tank body 1, wherein a tank body front section 2 and a tank body rear section 4 are respectively arranged in the tank body, a filter plate 3 for filtering overflow water mixed with partial coke foam is arranged between the tank body front section and the tank body rear section, the overflow water mixed with coke and coke foam enters the overflow tank through the tank body front section to enter the tank body rear section through the filter plate, and flows out from a water flow outlet of the tank body rear section, wherein a noise reduction device for eliminating water flow sound is further arranged in the tank body rear section, and the tank body front section is provided with water flow inlets 5 symmetrically arranged on two sides along an axis.
