Description

A kind of wheat washing machine washing tank

technical field

The utility model relates to a wheat washing trough for a wheat washing machine, in particular to a wheat washing machine washing trough for cleaning wheat before processing to remove dust, microorganisms, sandstones, pesticide residues, etc. attached to the wheat surface.

Background technique

During the process of wheat growth, harvesting, drying, transportation and storage, some dust, sand and some drug residues will adhere to the surface of the wheat and in the ventral groove, and at the same time, a certain amount of moldy grains, insect-eaten grains, germinated grains, and burnt grains will be produced. Grains, etc., seriously affect the quality of wheat. Therefore, in the milling process, the cleaning of raw grain wheat before milling has a significant impact on important indicators such as whiteness, purity, and ash content of processed flour. The water consumption of dry cleaning of wheat is small, but the cleaning effect of dust, microorganisms, insect eggs on the surface of wheat, sediment embedded in the ventral groove, side-by-side mud, cinder, and insect-infested wheat grains is not good, and it is difficult to produce High quality flour. Wet "washing wheat" can wash off the dust on the surface of wheat, wipe off part of the outer skin during the drying process, and float out shriveled wheat with no edible value and diseased wheat. Re-adopted by milling companies.

In the current wet cleaning, the wheat washing machine is widely used as the wheat wet cleaning equipment. After the wheat enters the wheat washing machine, it is only washed once in the wheat washing tank and then discharged. The cleaning distance is short. In order to improve the cleaning effect, we can only increase the injection of washing Therefore, the wheat washing trough used in the current wheat washing machine consumes a lot of water and causes serious pollution. Therefore, based on the existing wet cleaning technology, develop a wheat washing machine washing tank that saves water, can improve the cleaning effect of wheat at the same time, and has low energy consumption, which can reduce the pollution to the environment from the source, and also significantly reduce The production cost of the enterprise.

Contents of the invention

The utility model aims at the problems of short cleaning time, large water consumption and serious pollution in the current wet cleaning, adopts the three-time water washing and wheat washing technology of the combination of secondary elutriation and water spray fine washing, and separates coarse and fine washing. The technology of water recovery and recycling proposes a wheat washing machine washing tank with simple realization, high washing rate and effective utilization of water resources.

The technical solution to achieve the above object is: a wheat washing machine washing tank, which includes: a feeder, a rough elutriation tank connected with the feeder, a secondary washing elutriation tank connected with the coarse elutriation tank, a spray The tank is connected with the second washing elutriation tank;

The rough elutriation tank is placed horizontally, the rough washing auger runs through the secondary wash elutriation tank and the rough elutriation tank and is installed parallel to the bottom of the rough elutriation tank, and the bottom of the rough elutriation tank is installed with a gravel auger for cleaning The gravel that sinks to the bottom of the rough elutriation tank;

The section of the coarse washing auger located in the second washing elutriation tank has only a part of the auger blade, and one end of the bottom of the second washing elutriation tank is equipped with a sewage pipe for discharging the sewage produced by elutriation;

The spray tank is relatively long, and the inclined installation angle of the tank body is 30±2°. A spray pipe is installed in the middle and upper section for spray cleaning. The bottom of the tank is used for stirring and conveying the wheat in parallel, the lower section is located in the second wash elutriation tank to complete the second elutriation of wheat, the middle section and the upper section are located in the spray tank;

The middle section and the upper section of the bottom of the spray tank are multi-layer structures, the upper layer is equipped with a screen for draining water, and the bottom of the screen is a reclaimed water collection box for collecting the water drained by the screen and flowing back through the return pipe for rough elutriation. The trough is used for rough washing of wheat.

The utility model adopts the three-time water washing and wheat washing technology of separation of rough and fine washing, and adopts the mixed mode of rough elutriation, secondary elutriation and water spray fine washing instead of the primary elutriation of the transmission, so that the wheat enters the wheat washing machine and then successively washes the wheat trough. After rough elutriation, secondary elutriation and water spray fine washing, the cleaning rate is high and the impurity removal is more thorough.

The utility model implements the three-time water washing and wheat washing technology of the separation of coarse and fine washing in the same wheat washing machine washing tank, adopts an extended spraying tank, and the lower part of the spraying tank is connected with the secondary washing and elutriating tank for the secondary washing of wheat. For secondary elutriation, the middle and upper sections are used for water spray fine cleaning, and the upper section is used for draining. This scheme has a simple structure and realizes rough elutriation, secondary elutriation and water spray fine cleaning at the same time.

When the wheat washing tank of this wheat washing machine is working, after the wheat enters the rough washing tank through the feeder, during the soaking process, the rough washing auger stirs the wheat at the same time, and the silt mixed in the wheat sinks into the rough washing tank. At the bottom of the tank, under the low-speed push of the sand and gravel auger, it enters the sand collection box and is discharged regularly. At the same time, the wheat entering the rough elutriation tank is driven by the rotation of the coarse washing auger and then enters the secondary washing elutriation tank. During this process, the wheat Scrubbing in water in the coarse elutriation tank can initially wipe off the impurities on the surface of the wheat. After the wheat enters the secondary washing elutriation tank, the surface of the wheat is scrubbed twice under the agitation of the spray auger. The rotation of the dragon advances downward and moves forward. In the middle and upper section of the spray tank (4), the clear water sprayed by the spray pipe completes the further washing of the wheat. Draining is realized, and the drained reclaimed water is collected by the reclaimed water collection tank and then flows back to the rough elutriation tank through the return pipe to realize the reuse of reclaimed water.

When the wheat washing machine is working, the clean water is injected directly from the spray pipe, the spray flow is large, and the cleaning is more thorough. The reclaimed water generated by the spray cleaning enters the reclaimed water collection tank through the screen under the action of its own weight, without external power Compared with the water cycle device, and the existing water cycle recycling technology and device, the equipment structure of this scheme is simple, energy-saving and easy to realize.

When the wheat washing machine is working in the wheat washing tank, the reclaimed water produced by spraying and fine washing is collected by the reclaimed water collection box and then flows into the rough elutriation tank for rough elutriation of wheat, realizing the recycling of reclaimed water, which is different from traditional methods. In comparison, a ton of wheat only consumes 0.2-0.3 tons of water, which reduces environmental pollution from the source.
