Background
In the food production process, a centrifugal pump is commonly used for conveying liquid raw materials, the centrifugal pump works by utilizing the rotation of an impeller to enable water to generate centrifugal motion, the rotating impeller drives the water in a pump shell to generate high-speed rotation motion, the water generates centrifugal motion and is thrown to the outer edge of the impeller, and the water flows into a water pressing pipeline of the water pump through a flow channel of a volute pump shell. In the centrifugal pump transportation, because the blade stirs in liquid to and the friction between each spare part of centrifugal pump often can produce certain heat, but to some needs keep low temperature and volatile raw and other materials, it often can influence raw and other materials quality to be heated when the centrifugal pump, and liquid such as alcohol in the time of specially absorbs the heat after advancing the centrifugal pump, not only influences alcohol concentration, still very easily is heated and is sour, influences the finished product quality.
Disclosure of Invention
The purpose of the invention is as follows: the invention aims to provide an impeller for an alcohol process pump with a cooling function, aiming at overcoming the defects in the prior art, wherein the impeller has the function of cooling liquid in a pump body, and the pump body is prevented from generating heat during operation to influence the alcohol quality.
The technical scheme is as follows: in order to achieve the purpose, the invention provides an impeller for an alcohol process pump with a cooling function, which comprises a heat exchange cavity and blades, wherein the heat exchange cavity is hollow and cylindrical, the blades are uniformly distributed around the side surface of the heat exchange cavity, the interior of each blade is hollow, the blades are communicated with the hollow part of the heat exchange cavity, an impeller shaft is connected to the center of the heat exchange cavity, the impeller shaft is hollow, the hollow part of the impeller shaft is communicated with the hollow part of the heat exchange cavity, a closable opening is arranged on the heat exchange cavity, and liquid can be injected into the heat exchange cavity through the opening; the hollow part of the impeller shaft is movably connected with a heat exchange shaft, the end part of the heat exchange shaft extends into the heat exchange cavity all the time, the hollow part of the heat exchange shaft is provided with a liquid inlet channel and a liquid outlet channel, the liquid inlet channel and the liquid outlet channel are communicated at the end part of the heat exchange shaft, which is positioned in the heat exchange cavity, the other end of the heat exchange shaft is separated, and a sealing ring is arranged between the heat exchange shaft and the impeller shaft.
As an improvement of the scheme, a bearing is further arranged between the heat exchange cavity and the impeller shaft.
As an improvement of the scheme, heat exchange liquid is injected into the heat exchange cavity and the hollow part in the blade.
As an improvement of the scheme, the heat exchange cavity, the blades and the heat exchange shaft are all made of metal.
As an improvement of the scheme, the heat exchange cavity, the blades and the heat exchange shaft are all made of copper.
Has the advantages that: according to the impeller for the alcohol process pump with the cooling function, disclosed by the invention, the blades and the heat exchange cavity are hollow, the heat exchange liquid can be injected into the heat exchange cavity through the liquid inlet on the heat exchange cavity, the flowing cold liquid is injected into the heat exchange tube, and the liquid inlet channel and the liquid outlet channel in the heat exchange tube are communicated at the end part of the heat exchange shaft, which is positioned in the heat exchange cavity, so that the end part of the heat exchange tube in the heat exchange cavity can be regarded as a stable cold source. In the rotatory in-process of blade, the heat transfer liquid in heat transfer chamber and the blade is heated, because blade outer end linear velocity is the biggest, outer end blade and the interior liquid relative velocity of pump are big, consequently the blade outside is higher relatively in the heat that the impeller rotation in-process produced, the heat transfer liquid temperature rise that is close to the blade outer fringe in the blade is faster, and the heat transfer liquid of heat transfer chamber department is owing to be close to the cold source, the temperature is lower, to the heat transfer liquid, the temperature is lower, density is more little relatively, when the impeller is rotatory, because the effect of centrifugal force, the heat transfer liquid that is in lower heat transfer chamber department temperature can outwards move, the heat transfer liquid that is in the temperature is higher in the blade can move to the heat transfer intracavity, hotter heat transfer liquid carries out the heat transfer with the cold source in the.
The heat exchange cavity, the blades and the heat exchange shaft are all made of metal with good heat conducting performance, and the heat exchange speed can be guaranteed.
