Description

Technical Field

[0001] This utility model relates to the field of purification equipment technology, and in particular to a purification equipment for preparing platinum complex catalysts. Background Technology

[0002] In the preparation process of platinum complex catalysts, chloroplatinic acid is stirred with divinyltetramethyldisiloxane, then filtered to remove platinum black precipitate. Divinyltetramethyldisiloxane is then added and stirred until homogeneous, neutralized with sodium bicarbonate, and dried with anhydrous calcium chloride to obtain the platinum divinyltetramethyldisiloxane complex catalyst. Purification is a crucial step in this process, especially the removal of unreacted raw materials and byproducts (such as platinum black). Traditionally, filtration purification primarily uses a sand core funnel combined with vacuum filtration to remove platinum black. After filtration, platinum black recovery is required by collecting the platinum black on the filter membrane, dissolving it in aqua regia, and then recovering the platinum. However, the filter membrane in the existing sand core funnel is difficult to remove, requiring tools. This can easily cause the membrane to tip over, resulting in platinum black adhering to the container wall or tools, making complete recovery impossible. Utility Model Content

[0003] To address the aforementioned problems, this invention discloses a purification device for preparing platinum complex catalysts, which solves the problem that the filter membrane in the purification device cannot be quickly and completely removed.

[0004] The specific technical solution is as follows:

[0005] A purification apparatus for preparing a platinum complex catalyst includes a vacuum filtration flask, a vacuum filtration funnel, and a connector. A vacuum tube is connected to the side wall of the vacuum filtration flask via a vacuum nozzle. The connector includes a sleeve seat and a conduit. A sealing sleeve is fitted onto the outer side of the sleeve seat and is used to insert into the mouth of the vacuum filtration flask. A ring seat is provided in the middle of the inner wall of the sleeve seat, and a sealing gasket is placed on the top of the ring seat. The inner side wall of the ring seat is a conical surface, wider at the top and narrower at the bottom. The conduit passes through the sleeve seat, and the upper end of the conduit has a flared section in the shape of a conical funnel. The outer wall of the flared section and the inner wall of the ring seat are connected. The wall is matched, and a ring of support plates extends horizontally outward from the top of the flared part. The filter membrane is placed horizontally on the support plate, and the bottom of the support plate presses against the sealing gasket. A spring is sleeved on the lower end of the guide tube, and a support ring is provided on the side wall of the guide tube to support the bottom end of the spring. The top end of the spring presses against the bottom of the ring seat. The spring presses the guide tube downward and makes the support plate and the sealing gasket press against each other to achieve a seal. The bottom end of the suction funnel is provided with a tubular connecting part. The lower end of the connecting part is embedded into the upper end of the inner wall of the sleeve seat and is threaded and fixed thereto. The bottom end of the connecting part further presses the filter membrane and the guide tube downward to ensure a seal.

[0006] Furthermore, the outer wall of the sleeve seat is provided with a raised ring at both the upper and lower ends. The raised ring cooperates with the groove on the inner wall of the sealing sleeve, and the bottom end of the sealing sleeve is fitted onto the bottom end of the sleeve seat to achieve positioning between the sealing sleeve and the sleeve seat.

[0007] Furthermore, the outer wall of the sealing sleeve has a conical structure that is wider at the top and narrower at the bottom.

[0008] Furthermore, the bottom end of the sleeve seat corresponds to the position of the support ring, and the spring is located inside the sleeve seat.

[0009] Furthermore, a groove is provided on the outer wall of the conical surface of the flared portion, and a first sealing ring is fitted in the groove. The first sealing ring abuts against the inner wall of the conical surface of the ring seat to achieve a seal.

[0010] Furthermore, the outer wall of the top of the sleeve seat is provided with a baffle for supporting the mouth of the filtration bottle, and the outer wall of the connecting part is provided with a retaining ring for supporting the baffle.

[0011] Furthermore, a second sealing ring is fitted on the outer wall of the connecting part at the bottom of the retaining ring. The lower end of the connecting part is threadedly connected to the upper end of the sleeve seat, so that the retaining ring and the baffle cooperate to squeeze the second sealing ring to achieve sealing.

[0012] The beneficial effects of this utility model are reflected in:

[0013] In this connector, the conduit and the sleeve seat are elastically connected by a spring. By pushing the conduit upward, the filter membrane placed at the top of the conduit can protrude from the top of the sleeve seat, making it easy to remove the entire filter membrane. The operation is simple and convenient. Attached Figure Description
