Description

Reaction kettle Technical Field The invention relates to the technical field of experimental equipment, in particular to a reaction kettle. Background The reaction kettle is widely applied to the fields of chemical engineering, biological engineering, fermentation engineering and the like. Before the reaction kettle reacts, the kettle cover of the reaction kettle needs to be opened to put in reaction materials, and after the reaction is finished, the kettle cover needs to be opened to clean the inside of the reaction kettle so as to avoid the influence of residual materials on the next use. The kettle cover is opened and closed in a lifting mode of the kettle cover or the kettle body, and a clamping piece is usually required to be arranged between the kettle cover and the kettle body to realize the sealing between the kettle cover and the kettle body and the fixation of the kettle cover. If the lifting mode of the kettle cover is adopted, the height of the kettle body is higher in the practical operation process, the existing kettle cover lifting mechanism easily solves the problem that lifting is unstable, the kettle cover is easy to be stressed unevenly and shake in the lifting process, the kettle cover is moved to the opening direction of the kettle body by shaking, in the long-term use process, the shaking can lead to the damage of the parts on the kettle cover and the kettle body or the poor tightness between the parts, and the service life of the reaction kettle is influenced. For example, china patent document CN209522497U discloses a kettle cover lifting device for a reaction kettle, which comprises a support which is vertically arranged on the ground and used for supporting the lifting device, wherein the top of the support is provided with a rocker arm which is vertical to the support through a rotating shaft, the end part of the rocker arm is provided with a lifting mechanism used for lifting the kettle cover, the rocker arm of the kettle cover lifting device is connected with the kettle cover through a hook, the rocker arm is overlong, the kettle cover is easy to bear uneven force and shake when lifted, cannot be lifted and lowered stably and can shake left and right, and the service life of the reaction kettle is influenced. And the lifting mode of the kettle body is adopted, so that the lifting of the kettle body is realized by a high-strength lifting mechanism. For example, CN214439033U discloses a pneumatically lifting quick-opening reaction kettle of a kettle body, a clamp is arranged below a kettle cover mounting plate, and a contact surface between the kettle cover and the kettle body is surrounded when the clamp is closed. The reaction kettle realizes the opening and closing of the kettle cover and the kettle body by controlling the lifting of the kettle body with larger weight and volume through the air cylinder, and the structure diagram of the reaction kettle can show that a plurality of structural components are fixed on the kettle cover, and the opening and closing of the kettle cover and the kettle body can be realized in a more laborious mode that the lifting kettle body is selected just because the structure of the kettle cover is complex. And the contact surface of the kettle cover and the kettle body is surrounded when the clamp is closed between the kettle cover and the kettle body, so that the sealing of the kettle cover and the kettle body can be realized. Based on the above-mentioned problems, there is a need to provide a simple opening and closing mechanism for a kettle cover and a kettle body, and meanwhile, the problems of shaking and poor sealing caused by uneven stress in the lifting process are reduced. Disclosure of Invention The invention aims to provide a reaction kettle, which realizes stable lifting and falling of a kettle cover in the reaction process and ensures that the kettle cover and a kettle body have better tightness. In order to solve the above technical problems, an embodiment of the present invention provides a reaction kettle, including: A kettle body; the kettle cover is used for opening or sealing the kettle body; The connecting column is connected with the kettle cover; a connecting plate connected with one end of the connecting column, which is far away from the kettle cover, and The cylinder is a shaft cylinder, the cylinder shaft of the cylinder is connected to the connecting plate, and the cylinder shaft is used for driving the connecting plate and the connecting column to drive the kettle cover to reciprocate relative to the kettle body. In an embodiment, the connecting columns are at least two, and the connecting columns are equidistantly arranged around the center of the kettle cover. In an embodiment, the cylinder shaft comprises at least one piston rod, and two guide rods are arranged on two sides of the piston rod. In one embodiment, the cylinder axis is parallel to the connecting post and on the same side of the connecting plate. In one
