Description

Technical Field

[0001] This utility model relates to the field of emulsion reflux treatment technology, specifically an emulsion reflux treatment device for a pickling and rolling combined unit. Background Technology

[0002] Emulsions are high-performance semi-synthetic metalworking fluids that combine the lubricity and rust prevention of oil with the superior cooling properties of water, making them suitable for lubrication and cooling of the rolling mill in pickling and rolling combined processes.

[0003] During the operation of the emulsion, each application may cause dirty water to flow back into the emulsion, contaminating it and wasting it. Additionally, the temperature of the emulsion during operation also affects its effectiveness. Utility Model Content

[0004] The purpose of this invention is to provide a recirculation treatment device for emulsion in a pickling and rolling mill unit to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pickling and rolling mill emulsion reflux treatment device includes an emulsion tank, a demineralized water pipe, a cooling device, an air inlet pipe, a condenser pipe, and a vacuum filter. The emulsion tank and the cooling device are connected by pipes, the emulsion tank and the air inlet pipe are securely connected, the emulsion tank and the condenser pipe are securely connected, the air inlet pipe and the condenser pipe are connected by pipes, and the vacuum filter and the emulsion tank are connected by pipes.

[0007] Demineralized water, as one of the raw materials for the emulsion, is transported into the emulsion tank through a demineralized water pipe. When the temperature of the emulsion tank rises, the emulsion in the tank is cooled by a cooling device. When the temperature of the emulsion is too low, steam is transported through an air inlet pipe to heat the emulsion in the tank. The emulsion temperature rises due to heat exchange with the air inlet pipe. The steam in the air inlet pipe passes through a condenser pipe and is condensed into water under the action of the condenser pipe. Then, it flows out through the condenser pipe and passes through a vacuum filter to filter impurities in the returned emulsion. Finally, the filtered emulsion is sent back into the emulsion tank.

[0008] Furthermore, the emulsion tank and the demineralized water pipe are connected, and the demineralized water pipe is equipped with a demineralized water valve, which is an electronic valve. The demineralized water pipe is used to connect to the demineralized water produced in the workshop.

[0009] The demineralized water produced in the workshop is transported to the demineralized water pipe, and the demineralized water valve controls the time and rate at which the demineralized water is transported to the emulsion tank, thereby controlling the quality of the emulsion.

[0010] Furthermore, the cooling device is equipped with cooling water pipes, which are connected to the emulsion tank pipes.

[0011] When the emulsion temperature is too high, cooling water is supplied to the cooling water pipe through the cooling device. The cooling water flows through the cooling water pipe in the cooling device, carrying away the heat of the emulsion, thereby cooling the emulsion.

[0012] Furthermore, a steam input pipe is provided on one side of the air intake pipe, and the steam input pipe is connected to the air intake pipe. An air intake valve is provided on the air intake pipe, and the air intake valve is located near the middle of the emulsion tank.

[0013] The steam input pipeline is used to transport steam generated by the steam tank. When it is necessary to heat the emulsion, the steam in the steam input pipeline is opened so that the steam in the steam input pipeline can heat the emulsion in the emulsion tank through the air inlet pipe, preventing the emulsion temperature from being too low and reducing the emulsion's effectiveness.

[0014] Furthermore, a drain valve is installed on the condensate pipe. The drain valve is located near the bottom of the emulsion tank and is a steam trap.

[0015] When steam enters the condenser pipe from the intake pipe, it is condensed into water by the condenser pipe, and then the drain valve automatically opens to discharge the condensate.

[0016] Furthermore, a vacuum filter is installed above the emulsion tank, and an electrical control cabinet is mounted on the vacuum filter.

[0017] The electrical control cabinet, as the main power control device, is used to control the power distribution of the vacuum filter, enabling the vacuum filter to work efficiently.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. Equipped with a vacuum filter, when the emulsion is returned, the vacuum filter can filter the returned emulsion to prevent the returned emulsion from directly entering the emulsion tank. After filtration is completed, the filtered emulsion is sent back to the emulsion tank through the vacuum filter, effectively preventing the emulsion in the emulsion tank from being contaminated by the returned emulsion.

[0020] 2. By installing a cooling device, air intake pipe, and condensate pipe, the temperature of the emulsion is controlled, allowing the emulsion to operate within a suitable temperature range and improving its utilization efficiency. Attached Figure Description

[0024] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example: Figure 1 - Figure 2 As shown, this utility model provides a technical solution for an emulsion reflux treatment device for a pickling and rolling mill unit, including an emulsion tank 1, a demineralized water pipe 2, a cooling device 3, an air inlet pipe 4, a condensation pipe 5, and a vacuum filter 6. The emulsion tank 1 and the cooling device 3 are connected by pipes, the emulsion tank 1 and the air inlet pipe 4 are tightly connected, the emulsion tank 1 and the condensation pipe 5 are tightly connected, the air inlet pipe 4 and the condensation pipe 5 are connected by pipes, and the vacuum filter 6 is connected by pipes to the emulsion tank 1.

[0026] Demineralized water, as one of the raw materials for the emulsion, is transported into the emulsion tank 1 through the demineralized water pipe 2. When the temperature of the emulsion tank 1 rises, the emulsion in the emulsion tank 1 is cooled by the cooling device 3. When the temperature of the emulsion is too low, steam is transported through the air inlet pipe 4 to heat the emulsion in the emulsion tank 1. The emulsion temperature rises due to heat exchange with the air inlet pipe 4. The steam in the air inlet pipe 4 passes through the condenser pipe 5 and is condensed into water under the action of the condenser pipe 5. Then, it flows out through the condenser pipe 5 and passes through the vacuum filter 6 to filter impurities in the returned emulsion. Then, the filtered emulsion is sent back into the emulsion tank 1.

[0027] like Figure 1 As shown, the emulsion tank 1 and the demineralized water pipe 2 are connected. The demineralized water pipe 2 is equipped with a demineralized water valve 7, which is an electronic valve. The demineralized water pipe 2 is used to connect to the demineralized water produced in the workshop.

[0028] The demineralized water produced in the workshop is transported to the demineralized water pipe 2, and the demineralized water valve 7 controls the time and rate at which the demineralized water is transported to the emulsion tank 1, thereby controlling the quality of the emulsion.

[0029] like Figure 1 As shown, the cooling device 3 is equipped with a cooling water pipe 8, which is connected to the emulsion tank 1.

[0030] When the emulsion temperature is too high, cooling water is supplied to the cooling water pipe 8 through the cooling device 3. The cooling water flows through the cooling water pipe 8 in the cooling device 3, carrying away the heat of the emulsion, thereby cooling the emulsion.

[0031] like Figure 1 and Figure 2 As shown, a steam input pipe is provided on one side of the air intake pipe 4. The steam input pipe is connected to the air intake pipe 4. An air intake valve 9 is provided on the air intake pipe 4. The air intake valve 9 is located near the middle of the emulsion tank 1.

[0032] The steam input pipeline is used to transport steam generated by the steam tank. When it is necessary to heat the emulsion, the steam in the steam input pipeline is opened so that the steam in the steam input pipeline can be used to heat the emulsion in the emulsion tank 1 through the air inlet pipe 4, so as to prevent the emulsion temperature from being too low and reducing the effect of the emulsion.

[0033] like Figure 2 As shown, a drain valve 10 is provided on the condensate pipe 5. The drain valve 10 is located near the bottom of the emulsion tank 1 and is a steam trap.

[0034] When steam from the intake pipe 4 enters the condenser pipe 5, it is condensed into water by the condenser pipe 5, and then the drain valve 10 automatically opens to discharge the condensate.

[0035] like Figure 2 As shown, the vacuum filter 6 is installed above the emulsion tank 1, and the vacuum filter 6 is equipped with an electrical control cabinet 11.

[0036] The electrical control cabinet 11, as the main power control device, is used to control the power distribution of the vacuum filter 6, so that the vacuum filter 6 can work efficiently.

[0037] The working principle of this utility model is as follows: The demineralized water produced in the workshop is transported into the emulsion tank 1 through the demineralized water pipe 2. When the temperature of the emulsion tank 1 rises, cooling water is transported into the cooling water pipe 8 through the cooling device 3. The cooling water flows through the cooling water pipe 8 in the cooling device 3, carrying away the heat of the emulsion and lowering the temperature of the emulsion. When the temperature of the emulsion is too low, the air inlet valve 9 is opened, allowing the steam generated by the steam input pipe to heat the emulsion in the emulsion tank 1 through the air inlet pipe 4. After heating, the steam in the air inlet pipe 4 enters the condenser pipe 5 and condenses into water under the action of the condenser pipe 5. Then, the drain valve 10 automatically opens to discharge the condensate. When the emulsion flows back, the impurities in the returned emulsion are filtered through the vacuum filter 6. Then, the filtered emulsion is sent back into the emulsion tank 1.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
