Devices for Fluid Handling

Abstract

The invention discloses a device for fluid treatment, which comprises a central shaft body (1), and an upper valve body (2) and a lower valve body (5) stacked up and down are respectively sleeved outside the central shaft body (1), wherein the lower valve body The body (5) is fixed on a frame (16), the central shaft body (1) is fixedly connected with the lower valve body (5), the upper valve body (2) can rotate relative to the central shaft body (1), and the upper valve body (1) The body (2) and the lower valve body (5) can also rotate relatively; the upper valve body (2) and the lower valve body (5) are provided with a pipeline (11 / 14) that cooperates with each other; the device also A driving mechanism (13) is provided to drive the upper valve body, the main shaft and the upper end of the rotary distributor for indexing rotation, so as to realize the distribution of the fluid in the process inlet and outlet into different chemical containers according to requirements.

Description

technical field [0001] The invention relates to a device for chemical or physical treatment of fluids. Background technique [0002] This similar functional device is generally known in the prior art (for example, can refer to CN201080023936.6), and its public approach is to place the fluid processing column 2 (chemical reaction vessel) on a turntable that rotates around the central valve core, and drive The turntable or the spool rotates to realize the switching connection of the process pipeline. According to different application occasions, the total weight of the fluid treatment column 2 is usually in the range of more than 100 tons to more than 300 tons, which requires a set of strong enough The supporting and driving system drives these containers to run synchronously. Another technological requirement is that the driving process needs to be as fast and accurate as possible. In order to meet the support and precision requirements, the device is usually equipped with a ...

[0002] This similar functional device is generally known in the prior art (for example, can refer to CN201080023936.6), and its public approach is to place the fluid processing column 2 (chemical reaction vessel) on a turntable that rotates around the central valve core, and drive The turntable or the spool rotates to realize the switching connection of the process pipeline. According to different application occasions, the total weight of the fluid treatment column 2 is usually in the range of more than 100 tons to more than 300 tons, which requires a set of strong enough The supporting and driving system drives these containers to run synchronously. Another technological requirement is that the driving process needs to be as fast and accurate as possible. In order to meet the support and precision requirements, the device is usually equipped with a high-precision turntable, a control and detection system, and a high-strength foundation support. , the realization of these functions requires the user to pay a high cost. Due to the existence of a huge moment of inertia, it is usually very difficult to achieve fast rotation. As mentioned above, to support such a heavy load, the device needs to be equipped with a large number of supporting wheels and Bearings, these wheel sets and bearings will also bring additional costs to users in the future use and maintenance process
