The reactor is an important production equipment in the chemical product production industry, so the reactor is widely used in the chemical industry. In the reactor of the prior art, the reaction kettle is mostly connected with other equipment from the top cover, in and out and feed, such as the manhole for people in and out of the reactor, the observation hole for observing the situation in the reactor, the condensing hole connected with the condenser and the feed hole for feeding the reactor, etc. Therefore, the reaction kettle cover device of the chemical industry has many holes in addition to the feed. In the prior art, only one feeding hole is generally opened on the top cover of the reactor. Because in the chemical reaction process, it is necessary to constantly add new monomer chemical substances or additives to the reactor, especially sometimes it is necessary to add simultaneous oxidants and reducing agents, for chemical reactions that need to add a variety of monomer chemical substances, the opening of the feed hole of the reactor top cover is extremely inconvenient, and sometimes it will cause problems.
In order to overcome the technical problem of too few feeding holes on the cover of the reactor in the prior art. A new design of labor-saving device for opening the lid of a reactor is provided. The reactor cover opening labor-saving device comprises a cover body connected with the reactor, and the cover body comprises a manhole for people entering and leaving the reactor, a viewing hole for observing the situation in the reactor, a condensing hole connected with the condenser and a feeding hole for feeding the reactor, and the feeding hole is at least two. By setting multiple feed holes on the reactor cover saving device, a variety of chemical reaction substances or auxiliaries can be sent into the reactor from different feed holes at the same time.
