Problems solved by technology

Negative pressure filtration is the most commonly used operation in separation work, but the general suction filtration device can only filter one sample at a time, and the efficiency is relatively low
For seawater analysis that needs to process a large number of samples, it is time-consuming and laborious
For this problem, there is no good solution at home and abroad.

Embodiment Construction

[0007] like figure 1 As shown, the present invention includes a main pipe 2, a support 1 for fixing and supporting the main pipe. One end of the main pipe 2 is closed, and the other end is opened and an on-off valve 7 is installed. On the main pipe 2, four groups of suction and filtration branch pipes 5 are connected. One end of the main pipe 2 is provided with an on-off valve 4, and an air release valve 3 is provided near the open end. For the convenience of observing the degree of vacuum, a vacuum gauge 6 is also installed on the main pipe 2.

[0008] During use, the opening end of the suction and filtration branch pipe 5 is connected to the filter, and the main pipe is connected to the suction filtration bottle and the vacuum pump. Close the purge valve 3, open the on-off valves 4 and 7 on the branch pipe and the main pipe at the same time, and close the on-off valve 7 on the main pipe when the system reaches a predetermined vacuum degree. According to the reading of vacu...

Abstract

The invention unfurls a kind of filter of many heads. It include main tube, trestle for fixing main tube, the main tube has an open side a close side fixed switch. On the main tube, there are many other tubes, the side close to the main tube fixed switch. The invention's advantages are many operations at one time, separated switch, no effect to others, owning high effect, fast speed features. In the tube there is vacuum watch; tubes and trestle are made of plastic, so it also has the advantages of light and cheap.

Description

technical field [0001] The invention relates to a filtering device, more specifically a device capable of performing multiple sets of filtering operations simultaneously. Background technique [0002] Filtration refers to the operation of using a certain porous substance as a medium, and under the action of an external force, the liquid in the suspension passes through the pores of the medium, and the solid particles are trapped on the medium, thereby achieving solid / liquid separation. Negative pressure filtration is the most commonly used operation in separation work, but the general suction filtration device can only filter one sample at a time, and the efficiency is relatively low. For seawater analysis that needs to process a large number of samples, it is time-consuming and laborious. For this problem, there is no good solution both at home and abroad. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide...
