Abstract

The utility model relates to the field of chemical experimental equipment, and in particular relates to a chemical reaction kettle. The chemical reaction kettle comprises a motor, a coupler, an end cover, a gland, a kettle body, a stirring shaft, a first spiral vane belt, a second spiral vane belt, a three-vane sweepback stirring paddle and a catalytic gas distributor, wherein the three-vane sweepback stirring paddle is positioned at the bottom of the stirring shaft and above the catalytic gas distributor; the first spiral vane belt and the second spiral vane belt are arranged on the stirring shaft in a surrounding manner; a seal ring, a rotor and a radial moving body are arranged in a cavity formed between the gland and the end cover; the seal ring and the stirring shaft are in interference fit and are fixedly connected with the rotor; the rotor is connected with the radial moving body in a rotating manner; a preset moving gap is formed between the peripheral face of the radial moving body and the inner wall of the end cover; both the rotor and the radial moving body are formed by upper and lower parts which are buckled with each other. The chemical reaction kettle has high efficiency and uniform reaction, enables the seal ring to be constantly closely combined with the stirring shaft, and can be used for preventing gas in the kettle from escaping and prolonging the service life of the seal ring.

Description

A kind of chemical reaction kettle

Technical field

The utility model relates to equipment of chemical industry field, especially a kind of chemical reaction kettle.

Background technology

May there is when mounted the problem with the axiality deficiency of end cap in its shaft of traditional chemical reaction kettle, particularly when shaft rotate time because unbalance stress can be given the inhomogeneous radial load of shaft one, if now sealing ring and end cap are rigidly connected, this can cause sealing ring local deformation larger, a part of tightr another part and shaft of being combined with shaft is separated, the part separating can cause toxic gas in still to leak, traditional chemical reactor also Shortcomings aspect reaction efficiency and uniformity.

Utility model content

The utility model is intended to address the above problem, a kind of chemical reaction kettle is provided, the shaft that it has overcome traditional chemical reactor causes toxic gas in still to leak and the unequal problem of traditional chemical reactor reaction efficiency low reaction due to the axiality deficiency of alignment error and end cap or in rotation process because unbalance stress causes sealing ring local deformation greatly and shaft is separated when mounted, and its technical scheme adopting is as follows:

A kind of chemical reaction kettle, comprise motor, shaft coupling, end cap, gland, kettle, shaft, the first helical-blade band, the second helical-blade band, three leaf swept-back paddles and catalytic gas distributor, described catalytic gas distributor is set up in the bottom position place of cylindrical shell and is connected with the external world, described three leaf swept-back agitators are positioned at shaft bottom and are positioned at the top of catalytic gas distributor, described the first helical-blade band and the second helical-blade band are by being fixed in support bar on shaft around being arranged on shaft, the hand of spiral of described the first helical-blade band and the second helical-blade band is contrary, described end cap is installed on kettle top, described gland and end cap are by screw detachable connection, in the cavity forming between described gland and end cap, sealing ring is installed, rotor and radial-play body, described sealing ring and shaft interference fit and affixed with rotor, described rotor and radial-play body are rotationally connected, between the circumferential surface of described radial-play body and the inwall of end cap, there is default play gap, described rotor and radial-play body are by upper and lower two parts composition that is interlocked.

On technique scheme basis, the upper part of described radial-play body is processed with counterbore, and together with the upper part of described radial-play body is fixed in by holding screw with lower part, described holding screw is positioned at counterbore.

On technique scheme basis, described default play is provided with spring in gap.

The utlity model has following advantage: efficiency is high and reaction is even, can make sealing ring be combined closely with shaft all the time, has avoided the leakage of gas reactor, has extended the service life of sealing ring.
