Description

Technical Field

[0001] This utility model relates to the field of metal material processing technology, and in particular to a device for filtering and unblocking emulsion in cold rolling mills. Background Technology

[0002] A rolling mill is a new type of cold-rolling equipment for steel. It can process hot-rolled discs and steel coils into finished products for subsequent manufacturing. In some cold-rolling processes, steel plates need to be cold-rolled to create special structures. The emulsion system continuously supplies emulsion to the cold-rolling production process. The emulsion carries away the heat generated during rolling, reduces friction between the strip and the rolling mill, and cleans the strip and the rolling surface.

[0003] However, during the processing of metal sheets in a cold rolling mill, as the emulsion is recycled, a large amount of metal powder and other solid impurities accumulate in the emulsion. These impurities may clog the system and reduce the effectiveness of the emulsion. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a cold rolling mill emulsion filtration and unblocking device, which solves the problem that a large amount of metal powder and other solid impurities accumulate in the emulsion during the processing of metal sheets in existing cold rolling mills, and these impurities may clog the system and reduce the effectiveness of the emulsion.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0006] A cold rolling mill emulsion filtration and unblocking device includes a separation cylinder and a filter box. The top of the separation cylinder is equipped with an inlet pipe, and an electromagnet rod is vertically installed inside the separation cylinder. The electromagnet rod is electrically connected to a power supply installed at the bottom of the separation cylinder. A slag discharge pipe is provided on one side of the bottom of the separation cylinder, and the other side is connected to the filter box through a guide pipe. A liquid discharge pipe is provided on the filter box.

[0007] The inner wall of the filter box is provided with a metal screen, a microporous filter membrane and an activated carbon plate from front to back.

[0008] The metal screen, microporous filter membrane, and activated carbon plate are all fixedly installed inside the filter box by limiting plates set on both sides of the inner wall of the filter box.

[0009] Guide rails are installed on both sides of the top of the filter box.

[0010] A support frame is provided above the guide rail, and rollers are provided at the bottom of the support frame. The rollers are installed in conjunction with the guide rail. The main shaft of the rollers is fixedly connected to the output shaft of the fixed motor. Two electric push rods are vertically provided at the top of the support frame. A fixed plate is fixedly connected to the telescopic end of the electric push rods. A pressurized water pump is provided on the fixed plate. The water inlet of the pressurized water pump is connected to a water delivery pipe, and the water outlet of the pressurized water pump is connected to a pipe. Multiple evenly distributed nozzles are fixedly connected to the outer wall of the connecting pipe. The connecting pipe is connected to the bottom of the fixed plate through a fixed rod.

[0011] A control valve is fixedly connected to the middle of the guide pipe.

[0012] A valve is fixedly connected to the middle of the slag discharge pipe.

[0013] The beneficial effects of this utility model are:

[0014] (1) This utility model installs an electromagnet rod inside the separation cylinder and a power supply is installed at the bottom of the separation cylinder. When the emulsion carrying metal powder flows through the separation cylinder, the electromagnet rod will adsorb and separate the metal powder carried in the emulsion after being energized. Then the emulsion will flow into the filter box through the guide pipe for filtration so that the emulsion can be reused after filtration.

[0015] (2) This utility model can effectively remove tiny particles in the emulsion by installing a metal screen and microporous filter membrane inside the filter box. At the same time, the activated carbon plate can adsorb organic matter, pigments and odors in the emulsion, so that the emulsion can be reused after filtration.

[0016] (3) This utility model sets a support frame at the top of the filter box and installs an electric push rod. At the same time, a pressure water pump is installed in the middle of the fixed plate fixed at the output end of the electric push rod, and multiple nozzles are installed on the connecting pipe connected to the pressure water pump. Thus, high-speed water flow can be sprayed out through the nozzles to wash away the impurities accumulated on the filter medium and restore its filtration efficiency.

[0017] (4) The middle part of the guide tube of this utility model is fixedly connected with a control valve to adjust the emulsion flow rate, so that the electromagnet rod will fully adsorb and separate the metal powder carried in the emulsion after being energized.

[0018] (5) After the emulsion filtration is completed, the control valve on the guide pipe can be closed, and then the valve installed on the slag discharge pipe can be opened. Then the current of the electromagnet rod is cut off, so that the metal fragments adsorbed on the electromagnet rod fall to the bottom of the separation cylinder. Then water is injected into the separation cylinder, and the metal fragments can be flushed out of the separation cylinder through the slag discharge pipe. Attached Figure Description
