Fluid handling device

Abstract

The invention discloses a fluid treatment device which comprises a rack (16) and a lower valve body (5) fixed to the rack. A hollow main shaft (1) is arranged in the center of the device and provided with rotary distributors (7 and 8). An upper valve body (2) is arranged at the upper end of the main shaft. A pair of annular sealing plates (3 and 4) is arranged between the upper valve body and the lower valve body. Through holes are evenly distributed in the annular positions of the annular sealing plates with the center axis as a center in an inner ring and an outer ring. The through holes correspond to the upper valve body and the lower valve body respectively. Chemical reaction containers (17) are arranged around the rack of the device. The chemical reaction containers, the valve body sealing plates and the rotary distributors are connected through pipes (12, 11, 15, 10 and 9). The device is further provided with drive mechanisms (13) used for driving the upper valve body, the main shaft and the upper ends of the rotary distributors to do indexing rotation, and therefore fluid in a process feeding opening and discharging opening is distributed into the different chemical containers respectively according to needs.

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
