Description

Technical Field

[0001] This utility model belongs to the technical field of water treatment equipment, specifically relating to a cooling water supply system for an electric resistance furnace. Background Technology

[0002] As a core thermal equipment in the field of metal processing, the stable operation of resistance furnaces directly affects product quality, energy efficiency, and equipment lifespan. High-temperature heating elements, furnace doors, furnace linings, furnace necks, and key sealing components all rely on a circulating cooling water system for forced heat dissipation to prevent heat-induced failure. Therefore, the cooling water system of the resistance furnace is crucial for ensuring stable operation and directly determines whether the furnace can operate continuously, safely, and efficiently under harsh process conditions. Currently, most resistance furnaces use tap water for cooling, with some equipped with traditional sediment filters. This method has the following drawbacks: it only filters out some sediment from the tap water, resulting in poor filtration. With long-term use, impurities, including pipe corrosion products, can cause blockages in the cooling water pipes, requiring furnace shutdown for cooling and maintenance, thus affecting production. Utility Model Content

[0003] In view of the defects and deficiencies in the existing technology, this utility model provides a cooling water supply system for electric resistance furnaces to solve the technical problem of poor filtration effect in the existing cooling water supply system for electric resistance furnaces.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A cooling water supply system for an electric resistance furnace includes a first filter box and a second filter box arranged from bottom to top. The bottom plate of the first filter box is connected to an inlet pipe, and the top plate is connected to an outlet pipe. Both the inlet pipe and the outlet pipe are connected to the main water inlet pipe of the electric resistance furnace. The first filter box is equipped with a first backwater bay mechanism, and the second filter box is equipped with a second backwater bay mechanism.

[0006] This utility model also has the following technical features: Specifically, the first filter box and the second filter box have the same structure; the first filter box includes a box body that is open on one side, and a sealing cover that can seal with the box body.

[0007] Furthermore, the first filter box and the second filter box are connected by a connecting channel.

[0008] Furthermore, the first backwater mechanism includes a first base plate, on which a plurality of first upright plates are vertically spaced, and a first water outlet is provided on the first base plate at a position corresponding to the water inlet pipe.

[0009] Furthermore, the second backwater mechanism includes a second base plate, on which several second upright plates are vertically spaced, and a second water outlet is provided at the position corresponding to the connecting channel on the second base plate.

[0010] Furthermore, a first valve is installed on the water inlet pipe; a second valve is installed on the water outlet pipe; and a third valve is also installed on the main water inlet pipe of the electric resistance furnace.

[0011] Furthermore, the first filter box is equipped with a first pressure gauge; the second filter box is equipped with a second pressure gauge.

[0012] Furthermore, an observation window is provided on the side wall of the first filter box.

[0013] Furthermore, the main water inlet pipe of the resistance furnace is connected to multiple branch water inlet pipes of the resistance furnace.

[0014] Compared with the prior art, this utility model has the following technical effects: This utility model achieves the following effects through the deflection and sedimentation of the first and second filter boxes connected in series, and the first and second return water bay mechanisms set therein: (1) The multiple sets of vertical plates in the return water bay force the water flow to deflect and slow down, and large particles of mud and sand and rust products settle naturally in the first-stage box by gravity, without relying on the mesh for interception, which can effectively block mud and sand; (2) The first-stage coarse sedimentation + the second-stage fine sedimentation can effectively intercept impurities for the second time, and the impurity removal capacity is much higher than that of a single-layer filter screen; (3) Impurities settle at the bottom of the box, and there is no problem of filter screen blockage. The system operates with stable pressure difference and can be equipped with bypass valves to achieve cleaning without stopping the machine. In summary, this utility model can effectively filter the cooling circulating water, ensure the stable operation of the cooling circulating water of the resistance furnace, reduce the downtime caused by cooling water blockage, and improve production efficiency; this utility model has a simple structure, is easy to operate, and is easy to promote.

[0021] Example Following the above technical solution, such as Figures 1 to 3 As shown, this embodiment provides a cooling water supply system for a resistance furnace, including a first filter box 1 and a second filter box 2 connected from bottom to top. The bottom plate of the first filter box 1 is connected to an inlet pipe 3, and the top plate is connected to an outlet pipe 4. Both the inlet pipe 3 and the outlet pipe 4 are connected to the main water inlet pipe 5 of the resistance furnace. Preferably, both the inlet pipe 3 and the outlet pipe 4 are connected to the main inlet pipe 5 of the electric resistance furnace via a tee pipe, and the inlet end of the main inlet pipe 5 of the electric resistance furnace is connected to a water pump.

[0022] The first filter box 1 is equipped with a first backwater bay mechanism 6, and the second filter box 2 is equipped with a second backwater bay mechanism 7.

[0023] As a preferred embodiment, the first filter box 1 and the second filter box 2 have the same structure; like Figure 1As shown, the first filter box 1 includes a box body 101 open on the right side and a sealing cover 102 that can seal with the box body 101. The second filter box 2 also includes a box body open on the right side and a sealing cover that can seal with the box body 101.

[0024] As a preferred embodiment, the first filter box 1 and the second filter box 2 are connected by a connecting channel 8. In this embodiment, there are two connecting channels 8, which are spaced apart on the left and right sides of the top of the first filter box 1.

[0025] In a preferred embodiment, the first backwater mechanism 6 includes a first base plate 601, on which first upright plates 602 are vertically spaced. A first water outlet 603 is provided on the first base plate 601 at a position corresponding to the water inlet pipe 3. The multiple first upright plates 602 can block and buffer the water flow, reducing the water flow speed.

[0026] As a preferred embodiment, the second backwater mechanism 7 includes a second base plate 701, a plurality of second upright plates 702 are vertically spaced on the second base plate 701, and a second water outlet 703 is opened on the second base plate 701 at a position corresponding to the connecting channel 8.

[0027] As a preferred embodiment, a first valve 9 is provided on the water inlet pipe 3; a second valve 10 is provided on the water outlet pipe 4; and a third valve 11 is also provided on the main water inlet pipe 5 of the electric resistance furnace.

[0028] When filtration is required using the first filter box 1 and the second filter box 2, close the third valve 11 and open the first valve 9 and the second valve 10; when cooling water needs to be supplied directly through the electric resistance furnace water inlet pipe 5, close the first valve 9 and the second valve 10 and open the third valve 11.

[0029] As a preferred embodiment, a first pressure gauge 12 is provided on the first filter box 1; a second pressure gauge 13 is provided on the second filter box 2, and both the first pressure gauge 12 and the second pressure gauge 13 are used to measure pressure.

[0030] As a preferred embodiment, an observation window 14 is provided on the side wall of the first filter box 1. The observation window 14 is made of transparent material and is used to observe the filtration of mud and impurities in the first filter box 1.

[0031] As a preferred embodiment, the main water inlet pipe 5 of the electric resistance furnace is connected to a plurality of branch water inlet pipes 15 of the electric resistance furnace.

[0032] When using this utility model: Cooling water enters the first filter box 1 through the inlet pipe 3. The multiple first vertical plates 602 of the first return water mechanism 6 in the first filter box 1 buffer the high-speed flowing cooling water, reducing the water flow velocity and allowing solid impurities such as silt and pipe corrosion products in the water to settle naturally under gravity. After the initial filtration, the cooling water enters the second filter box 2 through the connecting channel 8. The second return water mechanism 7 performs secondary sedimentation filtration on the cooling water, further removing residual fine impurities in the water. This achieves secondary filtration of the cooling water, preventing the accumulation of silt and microorganisms directly entering the inlet water pipe of the electric resistance furnace, and ensuring stable cooling effect.

[0033] During the filtration process, the filtration status of sediment and impurities in the first filter box 1 can be observed through the transparent observation window 14. When it is found that the first return water trap mechanism 6 in the first filter box 1 needs to be cleaned, the first valve 9 and the second valve 10 can be closed, and the third valve 11 can be opened to allow cooling water to directly enter the resistance furnace inlet branch pipe 15 from the resistance furnace inlet main pipe 5. Then, the sealing cover of the first filter box 1 can be removed, the first return water trap mechanism 6 can be taken out, and the sediment can be manually cleaned. At the same time, the sealing cover of the second filter box 2 can also be opened, the second return water trap mechanism 7 can be taken out, and the sediment can be manually cleaned. Then, the cleaned first return water trap mechanism 6 and second return water trap mechanism 7 can be put back into the filter box.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
