Description

Technical Field

[0001] The present application relates to the technical field of steel rolling equipment, and in particular to an emulsion cooling device with a magnetic attraction function. Background Art

[0002] Emulsion is a high-performance semi-synthetic metalworking fluid used primarily in industries such as machining, metal rolling, and automotive manufacturing. Emulsions improve processing efficiency and product quality through their cooling, lubrication, and rust prevention properties.

[0003] During metal rolling, emulsion needs to be sprayed to achieve various purposes such as cooling. This part of the emulsion can then be collected, cooled and recycled again. However, a large amount of iron solid particles will be generated during the metal rolling process. These iron solid particles will be mixed into the emulsion, which also leads to a certain limitation in the number of cycles of the emulsion. Although magnetic suction equipment has been used for emulsion filtration in the prior art and there is also a corresponding emulsion cooling system, the magnetic suction and filtration of the emulsion exist separately, and the two have not been integrated. Utility Model Content

[0004] In view of the above problems, an embodiment of the present application provides an emulsion cooling device with a magnetic suction function, which organically integrates the magnetic filtration process and the cooling process of the emulsion and performs them simultaneously. Compared with the independent operation of the cooling device and the magnetic suction device in the prior art, this device has the characteristics of lower energy consumption and higher efficiency.

[0005] According to one aspect of an embodiment of the present application, an emulsion cooling device with a magnetic attraction function is provided. The emulsion cooling device with a magnetic attraction function includes a cooling box, a shunt pipe, a cooling air blower, a slag removal box, and a filter bag box. The cooling box is connected to a liquid outlet pipe, which is connected to a circulation pump. The water outlet of the circulation pump is connected to the middle of the shunt pipe via a first three-way valve. The two ends of the shunt pipe are connected to a slag removal box, each of which is provided with a magnetic filter. The bottoms of the two slag removal boxes are respectively connected to secondary pipes, the other ends of the two secondary pipes are connected to a second three-way valve, and the second three-way valve is connected to an emulsion spray pipe. The cooling air blower is connected to the top of the slag removal box via a pipe. The bottom of the slag removal box is connected to an exhaust pipe via a first solenoid valve. The other end of the exhaust pipe is connected to the bottom of one side of the cooling box via a second solenoid valve. A filter bag box is provided in the middle of the exhaust pipe near the slag removal box, and an air filter bag is provided in the filter bag box.

[0006] In some embodiments, the middle portion of the exhaust pipe is bent upward to form a U-shaped tube, and the highest point of the U-shaped tube is located above the liquid level in the cooling box.

[0007] In some embodiments, the exhaust duct is made of a transparent material.

[0008] In some embodiments, the bottoms of the secondary pipes are tilted, and the bottom ends of the secondary pipes are tilted downward and connected to the second three-way valve so that the two secondary pipes and the second three-way valve are V-shaped as a whole.

[0009] In some embodiments, ear plates are provided on both sides of the slag removal box, and the ear plates are screwed to the outer wall of the cooling box through screws. The top and bottom of the slag removal box are detachably connected to the diversion pipe and the secondary pipeline through rotating heads.

[0010] In some embodiments, the inner diameter of the slag removal box gradually shrinks from top to bottom, and a plurality of annular mounting platforms are arranged on the inner wall of the slag removal box from top to bottom, and a plurality of magnetic filter screens are overlapped on the mounting platforms. Two observation windows are provided on the outer wall of the slag removal box.

[0011] The beneficial effects of the present application are as follows: in the present application, the magnetic filtration process of the emulsion and the cooling process of the emulsion are effectively integrated into one, thereby reducing redundant components and reducing the overall size of the equipment. In the present application, by providing a cold air blower, on the one hand, the solid impurities in the slag removal box can be blown into the filter bag box for storage by blowing air, thereby reducing the frequency of cleaning the slag removal box. On the other hand, the low-temperature airflow blown in by the cold air blower will eventually carry the residual emulsion in the slag removal box into the cooling box, that is, avoiding the waste of emulsion when cleaning the slag removal box. At the same time, the low-temperature airflow can further reduce the temperature of the emulsion in the cooling box by heat exchange. In the present application, by providing two slag removal boxes and equipment such as the first three-way valve and the second three-way valve, the two slag removal boxes can work independently, and then the two slag removal boxes can be cleaned alternately without affecting the other slag removal box from continuing to work during the cleaning process.

The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only used as examples and cannot be used to limit the scope of protection of the present application.

[0021] Specifically, please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the overall cross-sectional structure of the emulsion cooling device with magnetic attraction function provided in an embodiment of the present application. Figure 2 This is a schematic diagram of the front view of the cooling box provided in an embodiment of the present application. Figure 3 for Figure 2 The enlarged view at point A, Figure 4Schematic diagram of the cross-sectional structure of the cooling box provided in the embodiment of the present application. The emulsion cooling device 100 with a magnetic suction function includes a cooling box 110, a diversion pipe 120, a cold air blower 130, a slag removal box 140 and a filter bag box 150, wherein the cooling box 110 can be a prior art, and generally, heat dissipation fins or a heat exchanger can be provided in the cooling box 110 to achieve the effect of cooling the emulsion therein. Since the cooling box 110 is a prior art and has been fully disclosed, it will not be described in detail here. The cold air blower 130 is used to inflate external cold air into the slag removal box 140. The slag removal box 140 is used to remove the slag from the emulsion that has been cooled in the cooling box 110, including using the magnetic suction component to adsorb the magnetic solid shell inside it to achieve the purpose of removal. The cooling box 110 is connected to a liquid outlet pipe 111, which is connected to a circulation pump 112. The circulation pump 112 can extract the emulsion in the cooling box 110 through the liquid outlet pipe 111 and spray it onto the working end surface of the metal rolling through the spray pipe after a series of actions. The water outlet of the circulation pump 112 is connected to the middle part of the diverter pipe 120 through the first three-way valve 113. The two ends of the diverter pipe 120 are respectively connected to a slag removal box 140. By setting the opening state of the first three-way valve 113, the emulsion in the cooling box 110 can be alternately pumped to the two slag removal boxes 140 for slag removal. The two slag removal boxes 140 operate alternately. At the same time, only one slag removal box 140 is in working state, while the other slag removal box 140 will be in standby state. At this time, the slag removal box 140 in standby state can be cleaned or replaced without affecting the operation of the entire equipment. A magnetic filter 141 is installed inside the slag removal box 140. Made of materials such as neodymium iron boron and permanent magnets, the magnetic filter 141 has strong magnetism and can adsorb magnetic solid impurities mixed in the emulsion onto the filter 141. The bottoms of the two slag removal boxes 140 are connected to secondary pipes 142, respectively. The other ends of the two secondary pipes 142 are connected to a second three-way valve 143, which is connected to an emulsion spray pipe 144. By controlling the second three-way valve 143 to control the connection between the two secondary pipes 142 and the emulsion spray pipe 144, the magnetically filtered emulsion in the slag removal box 140 can be sprayed from the emulsion spray pipe 144 onto the working end face of the metal rolling mill.The cooling air blower 130 is connected to the top of the slag removal box 140 through a pipe. The bottom of the slag removal box 140 is connected to the exhaust pipe 180 through a first solenoid valve 160. The other end of the exhaust pipe 180 is connected to the bottom of one side of the cooling box 110 through a second solenoid valve 170. A filter bag box 150 is provided in the middle of the exhaust pipe 180 near the slag removal box 140. An air filter bag is provided in the filter bag box 150 (the air filter bag is not shown in the figure). When one of the slag removal boxes 140 is in standby mode, there is a lot of emulsion residue in the slag removal box 140. Directly disassembling the slag removal box 140 for cleaning will cause a waste of this part of the emulsion. At this time, The cold air blower 130 blows a low-temperature airflow into the slag removal box 140. When the low-temperature airflow enters the slag removal box 140, it will carry the emulsion into the exhaust duct 180. At the same time, a small amount of solid impurities will pass through the magnetic filter 141 and enter the exhaust duct 180 together with the emulsion. Finally, driven by the low-temperature airflow, they will enter the filter bag box 150. The magnetic solid impurities that enter the exhaust pipe will be captured and intercepted by the air filter bag. The low-temperature airflow and the emulsion remaining in the slag removal box 140 will enter the cooling box 110 together. At the same time, the low-temperature airflow and the emulsion in the cooling box 110 will exchange heat to cool the emulsion. It should be noted here that in order to avoid excessive solid impurities remaining in the exhaust duct 180, the filter bag box 150 should be located as close to the slag removal box 140 as possible.

[0022] As can be seen from the above, in the embodiment of the present application, the magnetic filtration process of the emulsion and the cooling process of the emulsion are effectively integrated into one, thereby reducing redundant components and reducing the overall size of the equipment. In the present application, by providing a cold air blower 130, on the one hand, the solid impurities in the slag removal box 140 can be blown into the filter bag box 150 for storage by blowing air, thereby reducing the frequency of cleaning the slag removal box 140. On the other hand, the low-temperature airflow blown in by the cold air blower 130 will eventually carry the residual emulsion in the slag removal box 140 into the cooling box 110, thereby avoiding the waste of emulsion when cleaning the slag removal box 140. At the same time, the low-temperature airflow can further reduce the temperature of the emulsion in the cooling box 110 by heat exchange. In the present application, by setting up two slag removal boxes 140 and equipment such as the first three-way valve 113 and the second three-way valve 143, the two slag removal boxes 140 can work independently, and then the two slag removal boxes 140 can be cleaned alternately without affecting the other slag removal box 140 to continue working during the cleaning process.

[0023] In some embodiments, the middle portion of the exhaust duct 180 bends upward to form a U-shaped tube 181, with the highest point of the U-shaped tube 181 located above the liquid level in the cooling box 110. In this embodiment of the present application, this arrangement can, to a certain extent, prevent the coolant in the cooling box 110 from flowing back along the exhaust duct 180 into the filter bag box 150 or the slag removal box 140 under the influence of atmospheric pressure. In some embodiments, the exhaust duct 180 is made of a transparent material. In this embodiment of the present application, by making the exhaust duct 180 transparent, the state of the exhaust duct 180 can be easily observed.

[0024] In some embodiments, the bottoms of the secondary pipes 142 are inclined, and the bottom ends of the secondary pipes 142 are tilted downward and connected to the second three-way valve 143, so that the two secondary pipes 142 and the second three-way valve 143 form a V-shape. In the embodiment of the present application, due to the inclined bottoms of the secondary pipes 142, the emulsion in the secondary pipes 142 can be easily and completely discharged under the action of gravity.

[0025] In some embodiments, lugs 145 are provided on both sides of the slag removal box 140. The lugs 145 are screwed to the outer wall of the cooling box 110 via screws. The top and bottom of the slag removal box 140 are detachably connected to the shunt pipe 120 and the secondary pipe 142 via rotating heads 146. In this embodiment of the present application, the screws and lugs 145 facilitate the installation of the slag removal box 140 on the outer surface of the cooling box 110, and the rotating heads 146 enable the slag removal box 140 to be detachable from the shunt pipe 120 and the secondary pipe 142, thereby facilitating the removal of the slag removal box 140 for cleaning.

[0026] In some embodiments, the inner diameter of the slag removal box 140 gradually decreases from top to bottom. A plurality of annular mounting platforms 147 are sequentially provided on the inner wall of the slag removal box 140 from top to bottom. A plurality of magnetic filter screens 141 are overlapped on the mounting platforms 147. Two observation windows 148 are provided on the outer wall of the slag removal box 140. In the embodiment of the present application, the provision of the mounting platforms 147 facilitates the installation of the magnetic filter screens 141. Furthermore, since the inner diameter of the slag removal box 140 gradually decreases from top to bottom, the size of each magnetic filter screen 141 also decreases accordingly from top to bottom. Consequently, the magnetic filter screens 141 are not obstructed by the annular mounting platforms 147 during installation.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application. In particular, as long as there is no structural conflict, the various technical features mentioned in the various embodiments can be combined in any way. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions that fall within the scope of the claims.
