Description

Technical Field

[0001] The utility model relates to the technical field of rolling mills, in particular to a rolling mill emulsion circulation filtering system. Background Art

[0002] Currently, the emulsion tanks used in rolling mills are divided into dirty tanks and clean tanks, which are completely sealed by thick iron plates. The emulsion filter is placed 1.8 meters above the emulsion tank, supported by iron columns on all sides, and is roughly at the same height as the rolling mill.

[0003] In the prior art, the emulsion circulation filtration method when the copper product rolling mill is started for production is as follows: the clean box supply pump and the filter pump are turned on at the same time, the emulsion supply pump draws the emulsion in the clean box to the rolling mill for use, the used emulsion relies on gravity to return to the dirty box through the rolling mill return pipe, and then the dirty box filter pump of the dirty box draws the emulsion to the filter, and the filtered emulsion flows directly to the clean box through the return pipe.

[0004] This type of emulsion circulation filtration method requires the use of two pumps simultaneously when the rolling mill is started. If the dirty box filter pump is opened accidentally, the emulsion will overflow from the top of the dirty box, resulting in high energy consumption. In addition, the emulsion filtered by the filter will also contain copper powder. This copper powder is extracted by the emulsion supply pump to the rolling mill and is easy to damage the rollers after use, requiring frequent roller replacement. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a rolling mill emulsion circulation filtration system, in which the filter is directly installed on the top of the emulsion box through a support column, the emulsion discharged from the emulsion outlet of the rolling mill is directly sent to the filter through an emulsion collection and reflux component, the filtered emulsion is sent to the dirty box through a reflux arc pipe to station copper powder, the clean emulsion on the upper layer of the dirty box enters the clean box through a reflux inclined pipe, and the clean emulsion in the clean box is sent to the rolling mill for use through an emulsion supply component, which can save the energy consumption of a pump, and the copper powder content of the emulsion in the clean box is significantly reduced, thereby avoiding damage to the rollers of the rolling mill and reducing the replacement frequency of the rollers, which can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a rolling mill emulsion circulation filtration system, comprising a rolling mill, and further comprising:

[0007] The emulsion box body is provided with a partition plate inside, the partition plate divides the emulsion box body into a clean box on the left and a dirty box on the right, and the partition plate is provided with a circular hole, the circular hole connecting the clean box and the dirty box;

[0008] The filter is installed on the top of the emulsion tank, and the horizontal position of the top of the filter is lower than the bottom of the rolling mill;

[0009] The top of the emulsion collecting and reflux component is connected to the emulsion discharge port of the rolling mill, and the bottom of the emulsion collecting and reflux component is connected to the filter;

[0010] The bottom of the emulsion supply component is installed at the bottom of the clean box, and the top of the emulsion supply component is connected to the emulsion supply port of the rolling mill.

[0011] The emulsion flowing out of the rolling mill passes through the emulsion collection and reflux component into the filter for filtration, and then enters the dirty box. The emulsion containing copper powder stands still in the dirty box, and the copper powder sinks to the bottom. The upper emulsion enters the clean box through the circular hole. The clean emulsion in the clean box is extracted to the rolling mill through the emulsion supply component for use by the rolling mill.

[0012] Furthermore, it also includes support columns, and the bottom of the filter is fixedly connected to the top of the emulsion box through a plurality of support columns. The support columns are used to support and install the filter.

[0013] Furthermore, the emulsion collection and reflux assembly includes a collection branch pipe, a collection main pipe, and a reflux vertical pipe. The emulsion discharge outlet of the rolling mill is connected to the top of the collection branch pipe, the bottom of the collection branch pipe is connected to the upper side of the collection main pipe, the middle lower side of the collection main pipe is connected to the top of the reflux vertical pipe, and the bottom end of the reflux vertical pipe is connected to the inlet at the top of the filter. Multiple collection branches can be provided as needed. The emulsion discharged from the rolling mill enters the collection main pipe through the collection branch pipe, and then enters the filter through the reflux vertical pipe due to gravity and is filtered.

[0014] Furthermore, the filter further comprises a return arc pipe, wherein the outlet on the bottom side of the filter is connected to one end of the return arc pipe, and the other end of the return arc pipe is connected to the middle side of the dirty box. The emulsion filtered in the filter enters the dirty box through the return arc pipe.

[0015] Furthermore, the circular hole is located at three-quarters of the height of the partition plate and needs to be higher than the bottom of the reflux arc tube to prevent the emulsion containing copper powder in the reflux arc tube from entering the clean box through the circular hole.

[0016] Furthermore, it also includes a reflux inclined tube, and the reflux inclined tube is inserted into the circular hole.

[0017] Furthermore, the reflux inclined pipe is tilted with the left side lower and the right side higher, and a 45-degree angle is formed between the lower side of the reflux inclined pipe and the left side of the partition. Thus, the upper layer of emulsion in the dirty box enters the clean box through the reflux inclined pipe due to gravity.

[0018] Furthermore, the emulsion supply assembly includes an emulsion supply pump, a clean emulsion supply pipe, an emulsion partial pressure main pipe, and an emulsion supply branch pipe. The emulsion supply pump is installed at the bottom of the clean box, the outlet of the emulsion supply pump is connected to the bottom end of the clean emulsion supply pipe, the top end of the clean emulsion supply pipe is connected to the emulsion partial pressure main pipe, the upper side of the emulsion partial pressure main pipe is connected to the bottom end of the emulsion supply branch pipe, and the top end of the emulsion supply branch pipe is connected to the emulsion supply port of the rolling mill. The emulsion supply pump extracts the clean emulsion in the clean box, sends it to the emulsion partial pressure main pipe through the clean emulsion supply pipe, and then supplies it to the rolling mill through the emulsion supply branch pipe. Multiple emulsion supply branches can be provided as needed.

[0019] Compared with the existing technology, the beneficial effects of this rolling mill emulsion circulation filtration system are:

[0020] 1. The filter is directly installed on the top of the emulsion box through the support column. The emulsion discharged from the emulsion outlet of the rolling mill is directly sent to the filter through the emulsion collection and reflux component. The filtered emulsion is sent to the dirty box through the reflux arc pipe to stand copper powder. The clean emulsion on the upper layer of the dirty box enters the clean box through the reflux inclined pipe. The clean emulsion in the clean box is sent to the rolling mill for use through the emulsion supply component.

[0021] 2. It can save the energy consumption of a pump, significantly reduce the copper powder content of the emulsion in the clean box, avoid damage to the rollers of the rolling mill, and reduce the frequency of roller replacement. BRIEF DESCRIPTION OF THE DRAWINGS
