Description

A grain washing machine

technical field

The utility model relates to a grain elutriation equipment, in particular to a grain elutriation machine which cleans the grain before processing, and cleans away the dust, microorganisms, sandstone, pesticide residues and the like attached to the surface of the grain.

Background technique

During the process of growing, harvesting, drying, transportation and storage of grains, some dust, sand and some drug residues will adhere to the surface. Therefore, the grain must be cleaned before grain processing in order to ensure the quality of the finished product. At present, "wheat washing machine" is commonly used at home and abroad to complete grain washing. The existing wheat washing machine has a simple structure, which can wash away some impurities and dirt attached to the surface of the grain, and also has the function of removing stones. However, after the grain enters the wheat washing machine, it is discharged after only one elutriation, and the cleaning time of the material in the equipment is short. . In order to maintain the cleaning quality, the water supply can only be increased. Therefore, the current grain washing consumes a lot of water and causes serious pollution.

Therefore, based on the existing elutriation technology, it is necessary to develop a grain elutriation equipment that saves water, improves the grain cleaning effect, and has low cleaning costs, which can reduce environmental pollution from the source and significantly reduce The production cost of the enterprise.

Contents of the invention

The utility model aims at the problems of large water consumption and serious pollution in grain processing and elutriation, and proposes a grain elutriation equipment with simple realization, high cleaning rate and effective use of water resources by means of water recovery and recycling technology.

The technical solution to achieve the above purpose is: a grain elutriation machine, including a frame, an elutriation tank installed on the frame, an auger tank, a flow monitoring controller, a feeder installed on the elutriation tank, sand Stone auger, sand collection box, sewage pipe, washing auger installed on the auger tank, screen, return tank, spray pipe and grain discharger;

The inclination angle of the auger tank body is 25±2°. The washing auger is installed in the auger tank and parallel to the bottom of the auger tank. The bottom of the auger tank is a double-layer structure, and the upper layer is equipped with a screen for For draining, below the screen is a return tank to collect the water drained by the screen and flow back to the elutriation tank;

The elutriation tank is located at the lower end of the grain elutriation machine and communicates with the lower end of the auger tank. The sand and gravel auger is installed at the bottom of the tank and is driven by the elutriation auger through a pair of meshing gears. One end of the bottom of the tank is used to regularly discharge sand and gravel, and the sewage pipe is installed at the other end of the bottom of the tank to discharge sewage, and a screen is installed at the entrance of the sewage pipe;

The spray pipe is installed in the upper part of the auger tank, and the spray flow is controlled by a flow monitoring controller installed on the water inlet pipe.

After the grain enters the elutriation tank through the feeder, during the short soaking process, the lower end of the elutriation auger stirs the grain at the same time. Pushed at low speed, it enters the sand collection box and is discharged regularly. At the same time, the grains entering the auger tank are pushed forward by the rotation of the washing auger. The grains are scrubbed in water in the front tank to wipe off the impurities on the surface. In the trough, the clear water sprayed by the spray pipe completes the further washing of the grain, with a high washing rate and more thorough discharge of impurities; at the same time, the grain is further drained through the screen at the bottom of the trough while the grain is rotated and propelled in the back section of the trough. The reclaimed water is collected by the return tank and then flows back into the elutriation tank to realize the reuse of reclaimed water.

When the grain elutriation machine is working, clean water is injected directly from the spray pipe, and the reclaimed water produced by the spray cleaning is collected by the return water tank and flows into the elutriation tank for elutriation of the grain, realizing the recycling of reclaimed water, which is different from the traditional Compared with the method, the water saving is about 50%, and the pollution to the environment is reduced from the source.
