Description
Technical Field
The utility model belongs to the technical field of belted steel cold rolling emulsion filters, concretely relates to belted steel rolling emulsion filters and mud conveying system.
Background
The emulsion system is an important auxiliary system of the rolling mill and plays a role in cooling and lubricating. The cleanness of the emulsion and the content of iron powder are important guarantees for ensuring the surface quality of the strip steel. The emulsion of the rolling mill can be polluted to a certain degree in the circulating and using processes, and the emulsion can cause adverse effects on downstream processes and the quality of strip steel. Therefore, it is necessary to remove impurities such as iron powder in the emulsion by a magnetic filter and to minimize contamination of the emulsion.
At present, the proportion of high-strength steel and an automobile outer plate is further improved, and the product quality is seriously influenced by an emulsion filtering system under the condition that the product quality requirement is stricter. At present, the magnetic filter applied to a strip steel cold rolling emulsion system mainly comprises: vertical magnetic rod filters, magnetic plate filters, horizontal magnetic rod filters, and the like. Due to the structural characteristics of the vertical magnetic rod filter, the magnetic rods are sparse, the effective filtering area is small, and the requirements of high-quality strip steel on the cleanliness of emulsion in the prior art are difficult to adapt; the magnetic sheet filter is installed in the emulsion main tank body, and is immersed in the emulsion through permanent magnetism iron plate and adsorbs the iron powder, but its effective filtration area is little, and the performance is relatively poor, can't effectively get rid of the iron powder in the emulsion, and this system is unstable moreover, often has the magnetic sheet card to hinder the condition, leads to the unable operation of system. At present, the vertical magnetic rod filter is most widely applied to an emulsion system and mainly comprises dozens to hundreds of permanent magnetic iron rods according to the treatment capacity requirement, the magnetic rods are connected in series side by side through chains, the chains rotate to drive the magnetic rods to rotate circularly, when emulsion flows through gaps of the magnetic rods, iron powder particles are adsorbed on the magnetic rods, and the filtered emulsion flows back through overflow, so that the aim of filtering is fulfilled; but the arrangement form of the magnetic rod chain needs to be adaptively arranged according to actual working conditions, spatial positions, processing capacity requirements and the like.
However, in order to meet the requirement of large-flow filtration, the conventional vertical magnetic rod filter designs a magnetic rod chain into an L-shaped ring arrangement, as shown in fig. 2, the highest processing capacity of a single magnetic rod can reach 1000 m/h, the number of the single magnetic rods can reach about 300, and due to the reasons of magnetic rod weight, mechanical structure, equipment stability and the like, the capacity of the single magnetic filter cannot be continuously increased, so that when the flow is below 1000 m/h, the actual production requirement can be met by one magnetic filtration, and the economic efficiency is better; however, the actual flow rate of the emulsion box can reach 1500-.
In addition, the sludge filtered out by magnetic filtration contains iron powder and high grease, belongs to hazardous waste liquid, and is also an important part for conveying and treating the sludge filtered out by magnetic filtration in actual production. The current common treatment method is as shown in fig. 1, a set of sludge intermediate storage tank 3 is separately configured outside each emulsion tank 1, and comprises a stirrer, a heater, a humidifying device, a pipeline valve and the like, and finally the sludge intermediate storage tank is conveyed into a waste hopper by respective pumps. However, the sludge intermediate storage tank 3 and the pumping system have the problems of complex pipelines, high energy consumption, easy hardening and blockage of the pipelines, large occupied space and the like.
