Embodiment 1

[0029] Such as Figures 1 to 3 As shown, a casting and pouring filter device includes: a pouring bucket 1 , a filter mechanism, and a first filter net 3 .

[0030] Wherein, the pouring barrel 1 is a cuboid box with upper and lower ends open; the filter mechanism is arranged on a filter chamber 2 comprising an upside-down quadrangular platform, and four inclined side plates of the filter chamber 2 are installed with The second filter screen 10; wherein, the length and width of the interface on the filter cavity 2 are greater than the length and width of the pouring barrel 1, and are connected with the pouring barrel 1 by installing a transition plate 8, and the first filter screen 3 is installed Between the pouring barrel 1 and the filtering mechanism, it fits with the installation transition plate 8 and is fixed by a detachable connection.

[0031] As a preferred solution, the first filter 3 uses a high-silica glass fiber filter, and the second filter 10 uses a foam ceramic f...

Embodiment 2

[0045] On the basis of Example 1, a heating jacket 12 made of lightweight refractory brick material is installed in the middle and lower part of the filter chamber 2 (that is, below the second detection port 11), and the heating jacket 12 is wound with electromagnetic heating. The coil, the electromagnetic heating coil is connected with other control mechanisms and power supply, and the high-frequency current passes through the electromagnetic heating coil to heat the filter cavity 2 . Ensure that the temperature on the filter cavity 2 and the pouring barrel 1 is kept relatively constant, so as to avoid the appearance of solidified particles of the molten metal.

Abstract

The invention discloses a casting pouring filtering device and method, and belongs to the field of casting pouring. A pouring barrel, a filtering mechanism, a first filter net and a second filter net are included. The pouring barrel is a cuboid box with the upper end and the lower end opened. The filtering mechanism comprises a filter cavity which is an inverted quadruple prism frustum. The second filter net is arranged on four inclined side plates of the filter cavity. The first filter net is arranged between the pouring barrel and the filtering mechanism, and fixing is conducted through a detachable connection manner. The novel large-volume pouring barrel is provided, and the filtering volume is increased; through the arrangement of the multi-level filter nets, the filtering effect is improved; and a heating sleeve is arranged on the periphery of the filter cavity, and the filtering device can be preheated and subjected to heat preservation. Accordingly, the problems that existing filtering equipment is small in filtering flow, poor in filtering effect, poor in heat preservation effect and the like are solved.

Description

technical field [0001] The invention belongs to the field of casting and pouring, in particular to a casting and pouring filtering device and a filtering method. Background technique [0002] During the casting process, there are many factors that will affect the final quality of the casting. The casting will have impurities, bubbles, etc. In the prior art, the molten metal can be filtered to filter out the bubbles and air bubbles in the molten metal. Impurities, reduce impurities in molten metal, improve the quality of castings, so it is necessary to design a filter device for casting. [0003] After careful study of the existing equipment, the applicant found that the existing disclosed filtering equipment still has the following defects: 1. The filtering flow rate is small, which cannot meet the requirements of large-scale industrial production; 2. The filtering device has a single structure and poor filtering effect, reducing the The yield rate of the finished product a...
