Description
Technical Field
[0001] The utility model relates to the technical field of polypropylene diaphragms, in particular to a filtering container with a polypropylene diaphragm. Background Art
[0002] Polypropylene Membrane is a film made of polypropylene material, which is usually used in various filtration and separation processes. Polypropylene is a thermoplastic polymer with good chemical stability and corrosion resistance. Therefore, it is widely used in various industrial and laboratory environments after being made into a diaphragm. The main characteristics of polypropylene diaphragms include: good chemical stability, able to withstand corrosion from a variety of acids, alkalis and organic solvents, high mechanical strength: good tensile and tear resistance, excellent heat resistance: polypropylene material can remain stable at higher temperatures, usually operating temperature range between -40°C and +100°C, due to the excellent performance of polypropylene diaphragms, they are often used as filter media in various filter containers.
[0003] Existing filtering containers with polypropylene diaphragms are usually placed on the top of the container to filter impurities when used for impurity filtering in chemical solutions, pharmaceutical and food industries. However, when this method is used, the liquid will flow along the diaphragm to the outside of the container, resulting in solution waste, and some solutions will volatilize toxic gases. When filtering, the toxic gases will float in the air, causing harm to the workers. Therefore, in order to solve the above problems, a filtering container with a polypropylene diaphragm is proposed.

[0010] Preferably, the inner side of the rubber ring fits tightly with the outer side of the collecting balloon, and the inner side of the collecting balloon fits tightly with the outer side of the second joint.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. In the utility model, the fixed ring, the engaging groove, the sealing ring, the fixed plate, the reset spring, the hook, the container and the hanging ring are arranged, so that when the liquid is added into the container, the liquid can be prevented from flowing to the outside of the container along the diaphragm, causing the waste of solution. Before the liquid is added, the diaphragm body is placed inside the container, so that the container is engaged with the engaging groove at the bottom end of the fixed ring, and then the hook is pulled. At this time, the reset spring at the bottom end of the fixed plate is stretched, and then the hook is hung on the inside of the hanging ring. Due to the continuous force of the hook, the bottom end of the sealing ring inside the engaging groove can be tightly fitted with the top of the container. When the liquid is added, the liquid directly passes through the diaphragm body and enters the inside of the container. This design can prevent the liquid from flowing out of the gap between the diaphragm body and the container;
[0013] 2. In the utility model, by providing a fixing ring, a threaded ring, a rubber ring, a threaded cover, a first joint, a bottom-probing tube, a second joint, a collecting balloon and a rubber ring, when filtering a toxic solution, the toxic gas volatilized from the liquid can be mixed into the air. When the toxic solution needs to be filtered, the threaded cover is screwed onto the outside of the threaded ring until the top of the rubber ring fits tightly with the top of the inner side of the threaded cover, and the first joint is connected to the toxic solution. The toxic solution enters the inner side of the diaphragm body through the first joint and the bottom-probing tube and passes through the diaphragm body and flows into the inner side of the container. At this time, the toxic gas volatilized from the toxic solution enters the inner side of the collecting balloon through the second joint, and the collecting balloon expands. When the filtration of the liquid is completed, the rubber ring is removed from the outside of the collecting balloon, and the collecting balloon is removed and connected to the exhaust gas treatment device, and the filtration of the toxic solution can be completed.
