[0002] In the production process of aluminum alloy casting, filter box is needed to filter the slag in aluminum water, and the filter plate has a number of use requirements. Each time the filter plate is replaced, the flow will be stored. During the process of storing the flow, it is often found that the aluminum liquid has been filled in the filter chamber, but the aluminum liquid flowing out of the static chamber is very little. The reason for this is that the gas in the cavity between the filter plate and the bottom of the filter box is not easy to discharge, and some gas is trapped in the cavity under the filter plate, which prevents the aluminum liquid from passing through the filter plate normally, resulting in a decrease in the filtering efficiency of the aluminum liquid, a high gas content in the aluminum liquid and a decrease in the quality of the aluminum liquid. SUMMARY

[0003] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide an aluminum melt plate filter box exhaust device that avoids the situation where the air at the bottom of the filter plate cannot be discharged in time during the flow storage process, thereby improving the filtering efficiency of the aluminum liquid and the quality of the aluminum liquid and ensuring the safe and stable operation of the production.

[0004] The technical solution adopted by the utility model to solve the technical problem is as follows:

[0005] An aluminum melt plate filter box exhaust device includes a filter box and a filter plate. The middle part of the filter box is provided with a filter plate. An exhaust cylinder is arranged in the filter plate. There are two exhaust cylinders, and a sleeve is arranged outside each exhaust cylinder. Adjacent sleeves are connected together by a support handle and a plug-in cylinder. A connecting rod is arranged outside the sleeve. A plug-in slot is arranged at the bottom of the outer end of the connecting rod. A plug-in rod is arranged at the upper end of the exhaust cylinder.

[0006] A one-piece base is arranged around the bottom of the exhaust cylinder. The outer parts of the exhaust cylinder and the base are respectively provided with a molten corrosion-resistant coating.

[0007] The sleeve is sleeved outside the exhaust cylinder and is fixedly connected together with the exhaust cylinder by bolts.

[0008] The support handle is fixedly connected together with one of the sleeves, and the plug-in cylinder is fixedly connected together with the other sleeve. The end of the support handle is inserted into the plug-in cylinder and is fixedly connected together by bolts outside the plug-in cylinder.

[0009] The plug-in slot is inserted into the filter box and is fixed by bolts outside the plug-in slot.

[0010] At least four through holes are evenly arranged on the base.

[0011] The positive and beneficial effects of this utility model are:

[0012] 1. This utility model improves the filtration effect and quality of molten aluminum by installing an exhaust pipe in the filter chamber, which can promptly discharge the gas in the lower cavity of the filter plate; and by installing a plug at the upper end of the exhaust pipe, it is easy to remove the exhaust pipe from the filter chamber.

[0013] 2. This utility model provides a base at the bottom of the exhaust pipe to counterweight it and increase the contact area with the filter plate, thus ensuring the stability of the exhaust pipe.

[0014] 3. This utility model, by setting a sleeve on the outside of the exhaust pipe, and using the support handle and sleeve together, allows for free adjustment of the support handle and sleeve according to the width of the filter box. This makes it easy for workers to fix the slot to the side of the filter box, thereby fixing the exhaust pipe and preventing molten aluminum from entering the exhaust pipe from the bottom of the base. It is convenient to use and simple to operate. Attached Figure Description

[0019] The present invention will be further explained and described below with reference to the accompanying drawings:

[0020] See the example. Figs. 1-3 An exhaust device for an aluminum melt plate filter box includes a filter box body 1 and a filter plate 2. The filter plate 2 is arranged in the middle of the filter box body 1, and an exhaust pipe 3 is arranged inside the filter plate 2. There are two exhaust pipes 3, and a sleeve 6 is arranged on the outside of each exhaust pipe 3. Adjacent sleeves 6 are connected together by a support handle 7 and an insert 8. A connecting rod 10 is arranged on the outside of the sleeve 8, and a slot 11 is arranged at the bottom of the outer end of the connecting rod 10. An insert 5 is arranged at the upper port of the exhaust pipe 3.

[0021] An integral base 4 is provided around the bottom of the exhaust pipe 3, and anti-melting erosion coatings are respectively provided on the exterior of the exhaust pipe 3 and the base 4.

[0022] The sleeve 6 is fitted onto the outside of the exhaust pipe 3 and is fixedly connected to the exhaust pipe 3 by bolts on the outside of the sleeve 6.
