Description

[Detailed Description of the Invention] Industrial field of application The present invention relates to a sorting device for sorting dried foods such as dried sardines, dried sardines, dried vegetables, and kelp by specific gravity.

Conventional technology Conventionally, the work of sorting dry foods by weight and size is
Besides manual work, a sorting machine that vibrates a flat net to drop it from the mesh of the net, or a specific gravity type sorting machine that blows dry food with a forced fan and sorts from the distance of the drop point (here, specific gravity is the unit It is not the weight per volume, but the comparison of the weight against the wind pressure.

Problems to be Solved by the Invention However, the above-mentioned sorter using the net and the sorter using the forced fan have the following problems.

1) Due to forced vibration and large wind pressure from forced fans, dried foods are damaged and their commercial value is impaired.

2) The accuracy of foreign matter extraction is poor.

3) A large net and a space to blow it off are required, and the floor area is occupied widely.

4) The vibration of the net and noise from the blower make the work environment worse.

An object of the present invention is to solve the above problems and to provide a dry food specific gravity type sorting apparatus which improves sorting efficiency and accuracy, generates less noise, and does not damage products.

Means for Solving the Problems In order to solve the above-mentioned problems, the dry food specific gravity type sorting apparatus of the present invention has an outlet for air for sorting and a heavy foreign matter sorting port in an inclined plate with combing on both sides. And a baffle plate is provided at the lower end of the gap, and the suction hood is attached to the upper position of the inclined plate at an angle of 75 ° with respect to the inclined plate.The suction hood consists of the front plate, side plates, and rear plate. It is a box shape and has a baffle plate inside the suction hood and an intermediate damper between the baffle plate and the rear plate.The intermediate damper rotates around the horizontal pin and the lower end of the intermediate damper is rotated. The structure is such that the heavy product selection port between the and the jammer plate and the light product selection port between the upper end of the intermediate damper and the rear plate can be adjusted. Blowing noz It is provided with a supply fan blowing sorting air gap of the inclined plate through the.

In addition to the above configuration, on the lower outside of the intermediate damper,
A sliding plate for light specific gravity products is provided in parallel with the inclined plate, and it has a function of size classification.

Action In the above configuration, the products to be processed sent along the inclined plate are blown up by the sorting air blown out from the gap. At this time, the heavy foreign matter contained in the product to be processed cannot jump over the jammer plate and falls from the gap against the sorting air and is discharged. In addition, the product to be treated blown up by the sorting air and the air flow sucked up by the suction hood floats above the gap, and the product to be treated having a relatively large specific gravity cannot float above the intermediate damper, so It descends along and is discharged from the heavy product selection port between the jammer plate and the intermediate damper. Further, the product to be processed having a small specific gravity floats above the intermediate damper, descends along the rear plate of the suction hood, and is discharged from the light product selection port between the suction hood and the intermediate damper. Further, the light foreign matter having a small specific gravity is entrained by the air flow in the suction hood and is sucked toward the exhaust fan side to be separated.

Therefore, the product to be processed is sent by the inclined plate, and the product to be processed is floated and selected by using both the sorting air blown upward from the gap and the suction air sucked up from the suction hood, so that vibration and large amount of The product to be processed can be prevented from being damaged and the vibration and noise can be reduced without giving a shock to the product to be processed by a high-speed air flow. Moreover, by rotating the intermediate damper, the opening areas of the heavy product sorting port and the light product sorting port can be changed to arbitrarily separate and sort the products to be treated. Moreover, by blowing up the product to be processed in one gap formed on the inclined plate, heavy foreign substances are separated in the gap, products with a relatively large specific gravity are selected in the heavy product selection port, and light products with a relatively small specific gravity are selected in the light product selection. With the mouth, light foreign substances can be sucked by an exhaust fan to perform four types of sorting at a time, and the tilting plate and suction hood can also be small, making the whole compact.
