Embodiment 1

[0022] Example 1 Grain Sand Removal System

[0023] This desanding system consists of a buffer bin 1, a distributing machine 16, a desandering machine 13, a dewatering bucket elevator 18 and a product pool. 9 and so on. See the specific structure figure 1 , the buffer bin 1 is located above the distributing machine 16, and the distributing machine 16 is located above the desander 13. Consists of the desander tank body, bellows 4, sieve plate 15 and air bag 14 Composition, the tank body of the desander is a conical structure. The upper part of the desander tank body is rectangular, and the lower part is a conical structure with a large upper part and a smaller lower part. A discharge chute 8 is arranged above the desander tank body, and the discharge chute 8 communicates with the product pool 9. ， The bottom of the desanding machine body communicates with the soaking liquid supply pipe 20 . The bellows 4 is located above the sieve plate 15 and communicates with the bottom...

Embodiment 2

[0024] Example 2 Sand removal method

[0025] See figure 1 , the top of the sieve plate 15 is the material bed to be sorted, and the water level flowing in from the soaking liquid supply pipe 20 sees the water line 7 and does not pass through the bed. Close the exhaust valve 2 of the desanding machine, and open the air intake valve 3, when the air from the bellows 4 enters the air bag 14, the state after inflation is shown in image 3 , the air bag 14 expands in water and forces the surrounding water level to rise, and the rising water passes through the sieve holes of the sieve plate 15 to hold up the grain on the sieve, making the bed on the sieve plate 14 loose.

[0026] When the intake valve 3 is closed and the exhaust valve 2 is opened, the air in the air bag 14 is discharged from the exhaust valve 2 under the pressure of the surrounding water, and the water level falls back to see Figure 4 In the state after exhaust, a cycle is completed at this time. By controlling t...

Abstract

Disclosed are a grain degritting system and a degritting method thereof. A distributor is arranged above a degritting machine. The degritting machine comprises a machine trough, an air box and an air bag. A discharge chute is arranged above the machine trough and communicated with a product tank. The bottom of the machine trough is communicated with a soak solution delivery pipe. The air box is arranged above a screen and communicated with the bottom air bag of the machine trough. The air bag is fixed below the screen inside the machine trough and soaked in soak solution. The air bag is connected with one end of a tee, and other two ends of the tee are connected with an air source and the atmosphere through an intake valve and an exhaust valve in the air box, respectively. The lower portion of the screen is communicated with a screened content passage which is communicated with a grit chute. The grit chute is communicated with a bucket dewatering lift. A skimmer hopper is arranged in the bucket dewatering lift. The air bag is blown by air to form pulsating rising water flow to remove grit, the degritting method is simple, and energy conservation effect is significant.

Description

technical field [0001] The invention relates to a grain wet deep processing desanding equipment and a desanding process thereof, in particular to a grain desanding system for corn, soybeans, cassava and the like and a desanding method using the same. Background technique [0002] The raw materials purchased by corn, soybean, and cassava deep-processing enterprises all contain a small amount of sand and gravel, which must be removed before processing, otherwise it will affect product quality and cause wear and damage to subsequent equipment. At present, domestic grain deep processing enterprises mostly use water flushing chutes, hydrocyclones or wind desanding equipment to remove sand. , The second is that the gravel is not removed cleanly, causing a lot of waste and equipment wear and tear. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies in the prior art. One is to provide a method of using air to agitate the air bag ...
