[0027] Please refer to the attached Figure 1In one embodiment of the present invention, a water circulation system of a roller bottom quenching machine 110 is provided, which includes a quenching mechanism 10, a water storage mechanism 20, a filtering mechanism 30 and a cooling mechanism 40. First of all, it should be noted that the water circulation system of the quenching machine 110 in the prior art sometimes requires the cooperation of technicians during operation, has a low degree of automation, and has sewage discharge problems after water treatment. The present application solves the above-mentioned defects in the prior art by setting up a water circulation system of a roller bottom quenching machine 110. The details are as follows:

[0028] The quenching mechanism 10 has a water inlet and a water outlet. The water inlet of the quenching mechanism 10 is connected to the cooling mechanism 40, the water outlet of the quenching mechanism 10 is connected to the water inlet of the water storage mechanism 20, the water outlet of the water storage mechanism 20 is connected to one end of the filtering mechanism 30, and the other end of the filtering mechanism 30 is connected to the cooling mechanism 40.

[0029] Specifically, the water circulation system of the roller bottom quenching machine 110 in the present application includes a quenching mechanism 10, a water storage mechanism 20, a filtering mechanism 30 and a cooling mechanism 40. The quenching mechanism 10 is a steel plate heat treatment line equipment with the roller bottom quenching machine 110 as the main body; the water storage mechanism 20 is used to store hot waste water generated after the quenching mechanism 10 is working; the filtering mechanism 30 is used to treat the hot waste water in the water storage mechanism 20 to filter and purify the hot waste water, which does not need to be discharged and can be further utilized, thereby improving the utilization rate of water; and the cooling mechanism 40 is used to cool the hot water after the filtration and purification, so that the cooled water can continue to be used for the quenching mechanism 10.

[0030] The quenching mechanism 10 has a water inlet and a water outlet. The water inlet of the quenching mechanism 10 is used to receive cold water from the cooling mechanism 40 after cooling. After receiving the cold water, it is used to supply the roller bottom quenching machine 110. Therefore, the water inlet of the quenching mechanism 10 is connected with the cooling mechanism 40, and the water outlet of the quenching mechanism 10 is used to discharge the hot waste water generated after high-temperature operation. By connecting the water outlet of the quenching mechanism 10 with the water inlet of the water storage mechanism 20, the hot waste water generated after high-temperature operation is discharged to the water storage mechanism 20. 0, the water storage mechanism 20 collects and stores hot waste water while inputting the stored hot waste water into the filtering mechanism 30, which performs purification treatments such as advection and filtration, and then outputs the hot waste water to the cooling mechanism 40 for cooling after treatment, so that the cooled water is supplied to the quenching mechanism 10 for use, thus forming a closed-loop water circulation system, ensuring the recycling effect of water, improving production efficiency, and eliminating sewage discharge problems; it is worth mentioning that each mechanism can be connected by a water pipe, which is convenient for installation and connection, and has low cost.

[0031] As a preferred embodiment of the utility model, the filtering mechanism 30 includes a horizontal flow pool 310, a horizontal flow pool lifting pump 320 and a high-speed filter 330. The water outlet end of the water storage mechanism 20 is connected to the horizontal flow pool 310, the horizontal flow pool lifting pump 320 is connected between the horizontal flow pool 310 and the high-speed filter 330, and the other end of the high-speed filter 330 is connected to the cooling mechanism 40.

[0032] It should be noted that the filtering mechanism 30 includes a horizontal flow tank 310, a horizontal flow tank lifting pump 320 and a high-speed filter 330. The horizontal flow tank 310 is used to remove suspended particles in sewage and purify water quality, while reducing the burden on subsequent water treatment equipment and improving treatment efficiency; and the high-speed filter 330 is used to further filter turbid matter in the water and improve water quality. It is one of the more commonly used water treatment equipment in the steel production industry. The horizontal flow tank lifting pump 320 absorbs the water that has been preliminarily treated in the horizontal flow tank 310 and discharges it into the high-speed filter 330 for further treatment; after such comprehensive treatment, the sewage discharge problem is solved, the working environment is purified, and the green manufacturing development of the steel industry is effectively guaranteed.

[0033] As a preferred embodiment of the utility model, the cooling mechanism 40 includes a cooling tower 410 and a cold water pool 420, the other end of the high-speed filter 330 is connected to the cooling tower 410, the cooling tower 410 is connected to the cold water pool 420, and the water outlet end of the cold water pool 420 is connected to the quenching mechanism 10.

[0034] It should be noted that the cooling mechanism 40 includes a cooling tower 410 and a cold water pool 420. The cooling tower 410 is a device that utilizes the principle of heat exchange for cooling, absorbs heat from a system and discharges it into the atmosphere to reduce the water temperature. Since the clean water treated by the high-speed filter 330 is in a high-temperature state before treatment, in order to ensure that it can continue to circulate and supply later, the other end of the high-speed filter 330 is connected to the cooling tower 410 so that the filtered high-temperature water can be directly passed into the cooling tower 410 for cooling, and the cooled water is discharged into the cold water pool 420 for collection and storage for absorption and use by the quenching mechanism 10.

[0035] It is worth mentioning that the agent can be added to the cold water pool 420 at regular intervals according to the flow rate of the water pool for sterilization. The agent can be polyaluminum chloride, polyferric sulfate, polyacrylamide, etc. The equipment for adding the agent can be composed of metering pumps, solenoid valves and other equipment. It is a technology well known to those skilled in the art and can be selected according to actual needs. It will not be described in detail here.

[0036] As a preferred embodiment of the utility model, the quenching mechanism 10 includes a quenching machine 110 and a quenching water supply pump 120, one end of the quenching water supply pump 120 is connected to the water outlet end of the cold water pool 420, the other end of the quenching water supply pump 120 is connected to the first end of the quenching machine 110, and the second end of the quenching machine 110 is connected to the water storage mechanism 20.

[0037] It is worth noting that the quenching mechanism 10 includes a quenching machine 110 and a quenching water supply pump 120. The quenching water supply pump 120 is used to absorb the filtered and cooled water stored in the cold water tank 420, and then input the absorbed water into the quenching machine 110 for use.

[0038] As a preferred embodiment of the present invention, the advection pool 310 is arranged higher than the water storage mechanism 20 .

[0039] It is worth noting that, since the advection pool 310 can settle particles by gravity, in order to further ensure the sewage treatment effect of the advection pool 310, the advection pool 310 is set higher than the water storage mechanism 20 to form a height difference to enhance the gravity effect.

[0040] Furthermore, the water storage mechanism 20 includes a hot water pool 210 and a hot water pool lifting pump 220, the second end of the quenching machine 110 is connected to the hot water pool 210, the hot water pool lifting pump 220 includes a high end and a low end, the water outlet end of the hot water pool 210 is connected to the low end of the hot water pool lifting pump 220, and the high end of the hot water pool lifting pump 220 is connected to the advection pool 310.

[0041] It should be noted that the water storage mechanism 20 includes a hot water tank 210 and a hot water tank lifting pump 220. The hot water tank 210 is used to collect and store the hot waste water discharged from the quenching machine 110. Since the advection tank 310 is arranged higher than the water storage mechanism 20, the hot water tank lifting pump 220 is required to pump the hot waste water from a low place to a high place to transfer it to the advection tank 310.

[0042] Furthermore, the cooling mechanism 40 further includes a cooling fan 430 , and the cooling fan 430 is disposed in the cold water pool 420 and is disposed toward the cold water pool 420 .

[0043] It should be understood that the cooling fan 430 can further help cool the water in the cold water pool 420 .

[0044] Furthermore, the cooling mechanism 40 further includes a temperature detector 440 , and the temperature detector 440 is disposed on the cold water pool 420 .

[0045] It should be noted that the temperature detector 440 is used to detect the water temperature in the cold water pool 420 in real time to ensure normal use of subsequent supply. If the temperature is too high (for example, in a preferred embodiment, the water temperature is greater than 35°C), the operating frequency of the cooling fan 430 can be increased to speed up the cooling efficiency.

[0046] Furthermore, the filtering mechanism 30 also includes a pressure detector 340 , and the pressure detector 340 is disposed at the water outlet end of the advection pool lifting pump 320 .

[0047] It should be noted that the pressure detector 340 is used to ensure the same frequency operation of the lifting pump. When the required pressure cannot be reached (for example, in a preferred embodiment, it cannot be higher than 50Hz and not lower than 35Hz), the pressure control can be achieved by adding or subtracting the number of pumps; it is worth mentioning that, in addition to the advection tank lifting pump 320, the quenching water supply pump 120 and the hot water tank lifting pump 220 can also be arranged in this way.

[0048] Furthermore, the number of the hot water pool booster pumps 220 is three, and the three hot water pool booster pumps 220 are arranged side by side.

[0049] It can be understood that, as a preferred embodiment of the present application, the number of the hot water pool booster pumps 220 is three, and the required pressure value can be achieved by multiple pumps working together.

[0050] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
