Abstract
The utility model relates to an IPA feeding pipeline with a bypass, comprising a feeding cabin (1) and a slurry preparing pot (2), wherein the feeding cabin (1) and the slurry preparing pot (2) are connected through a main pipeline (3); the main pipeline (3) is provided with a screw measuring feeding machine (4) and a rotary valve (5), wherein the screw measuring feeding machine (4) is connected with a bypass (6) in parallel; and the bypass (6) is provided with a control valve (7). The screw measuring feeding machine of the IPA feeding pipeline with the bypass is connected with the bypass in parallel, and the main pipeline is provided with the rotary valve so as to precisely control the baiting speed when the screw measuring feeding machine breaks down and maintain the screw measuring feeding machine conveniently.
Description
Technical field
The utility model relates to a kind of feed lines, relates in particular to a kind of IPA feed lines that has bypass, belongs to the chemical industry equipment field.
Background technology
In traditional polyester production process; The feeding required precision of dimethylcarbinol (IPA) is higher; The feed lines of IPA is provided with the blanking velocity that a screw rod metering feeding machine is used for controlling the IPA feeding bin, when screw rod metering feeding machine breaks down, owing to have only a trunk line; The operation that need stop complete equipment just being keeped in repair, very inconvenience.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of IPA feed lines that has bypass that can accurately control blanking velocity and convenient for maintaining is provided.
The purpose of the utility model is achieved in that a kind of IPA feed lines that has bypass; Comprise feeding bin and slurry preparing tank; Connect through trunk line between said feeding bin and the slurry preparing tank; Said trunk line is provided with screw rod metering feeding machine and rotary valve, and said screw rod metering feeding machine is parallel with a bypass, and said bypass is provided with control valve.
Compared with prior art, the beneficial effect of the utility model is:
The utility model screw rod metering feeding machine is parallel with a bypass, and trunk line is provided with rotary valve, accurately controls blanking velocity and convenient for maintaining in the time of can making screw rod metering feeding machine fault.
