Description
Technical Field
The utility model relates to a raw materials supply part in the feed processing equipment especially involves fodder and adds molasses equipment.
Background
Molasses is a byproduct of sugar manufacturing industries such as sugarcane, beet and the like, and is used as a feed raw material with high quality and low price in countries such as Europe and America and countries and regions of Asia, so that the molasses is very popular. Molasses is used as a feed raw material with high quality and low price, is gradually popularized and used in the feed processing industry of China at present, and is more and more valued by people. The molasses is not only an energy raw material, but also has the advantages of fast digestion and absorption, palatability improvement, dust reduction, granule quality improvement and the like.
However, molasses is characterized by high viscosity, and in the feed production process of general enterprises, a molasses mixer is used for adding molasses to feed, the molasses mixer is a special molasses adding device and is a continuous mixer, the working principle is similar to that of a modulator, high rotating speed is selected, the increase and mixing of molasses are satisfied, and the residual quantity is reduced together. In the production process, the molasses mixer is used after the conventional ingredient mixer, the independent molasses is added to mixing, the defect that the conventional mixer is added to the molasses is eliminated, and the percentage of the molasses can be increased. On one hand, the molasses is easy to stay in the molasses conveying pipeline due to the high viscosity of the molasses, and once the molasses is pumped into the weighing barrel by the pump at an excessively high speed, the pressure in the pipeline is easy to be overlarge; on the other hand, when the upper valve of the weighing barrel reaches the weighing weight, the upper valve is automatically closed, but at the moment, the pump cannot be stopped in time due to inertia, and the pipeline pressure is too high due to the retention of molasses; for the two reasons, once the pressure of the pipeline is too high, molasses can be sprayed out from the gap of the pipeline, on one hand, the molasses raw material is wasted, and on the other hand, the molasses outflow is difficult to clean.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems that in the prior art, molasses is easy to stay in a molasses conveying pipeline due to high viscosity, and once a pump pumps molasses into a weighing barrel at an excessively high speed, the pressure in the pipeline is easy to be excessively high; on the other hand, when the upper valve of the weighing barrel reaches the weighing weight, the upper valve is automatically closed, but at the moment, the pump cannot be stopped in time due to inertia, and the pipeline pressure is too high due to the retention of molasses; reason based on above two aspects is in case pipeline pressure is too big, can make molasses follow pipeline gap blowout, extravagant molasses raw materials on the one hand, and on the other hand molasses outflow is difficult to the technical problem of clearance, the utility model provides a fodder adds molasses system can realize slowly getting into the bucket of weighing with molasses, avoids pipeline pressure to make raw materials blowout too big, has practiced thrift production and human cost. In order to realize the technical effect, the utility model discloses following technical scheme has been taken.
A feed molasses adding system, which comprises a molasses raw material barrel, a pump machine, a variable frequency motor, a weighing barrel, a feed mixer and a control unit, wherein,
