Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to a chemical reaction vessel that facilitates bottom stirring. Background Technology

[0002] A chemical reaction vessel consists of a vessel body, a stirring device, a transmission device, a shaft sealing device, a heating / cooling device, and auxiliary components. The vessel body provides the reaction space, and the stirring device mixes materials with the impeller through a stirring shaft. Traditional top-stirring designs suffer from insufficient bottom stirring. Due to the gap between the impeller and the bottom of the vessel, high-viscosity, easily sedimenting, or particulate materials tend to accumulate at the bottom, forming dead zones that affect mixing uniformity and consequently reduce reaction efficiency, product quality, and yield. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the existing reaction vessels have insufficient bottom stirring. Because there is a gap between the impeller and the bottom of the vessel, high viscosity, easy-to-settle or particulate materials tend to accumulate at the bottom, forming a flow dead zone, which affects the uniformity of mixing, and thus reduces the reaction efficiency, product quality and yield.

[0004] To solve the above problems, the technical solution adopted by this utility model is a chemical reaction vessel that facilitates bottom stirring, including a tank body. A tank cover is fixed to the top of the tank body by several bolts and nuts. A stirring shaft is rotatably provided in the middle of the tank cover. Several stirring blades are fixed to the bottom of the stirring shaft. A gear one is fixed to the side of the stirring shaft near the top. A gear two that meshes with gear one is rotatably provided on the lower side of the tank cover. A limiting ring groove is opened on the inner side of the tank cover. An internal meshing toothed ring that meshes with gear two is rotatably provided in the limiting ring groove. A pair of curved rods are symmetrically fixed to the lower side of the internal meshing toothed ring. An arc-shaped stirring rod is fixed to the bottom of the curved rod.

[0005] As a further embodiment of this utility model: a support frame is fixed to the top of the can lid, and a motor electrically connected to an external power source is fixed to the top of the support frame. The output end of the motor is fixed to the stirring shaft and is used to drive the stirring shaft to rotate.

[0006] As a further embodiment of this utility model: the upper side of the tank lid is provided with a feed inlet, a temperature control hole, and a sampling hole for feeding, temperature control, and sampling, respectively, and the bottom of the tank is provided with a discharge outlet for discharging materials.

[0007] As a further embodiment of this invention: several support legs are fixed at the bottom of the tank to support the reaction vessel.

[0008] As a further embodiment of this invention: the lower side of the arc-shaped stirring rod is in contact with the bottom surface of the tank to facilitate uniform stirring of the material at the bottom.

[0009] Compared with the prior art, the advantages of this utility model are as follows: This application adds a gear transmission structure and an arc-shaped stirring rod. The gear transmission structure drives the arc-shaped stirring rod to rotate, which facilitates the stirring of the raw materials at the bottom of the tank, making the raw materials mix evenly and improving work efficiency.
