Description

Technical Field

[0001] The utility model relates to the technical field of pine nut processing equipment, in particular to a novel impurity removal and screening device for pine nut processing. Background Art

[0002] Pine nuts, also known as pine nuts, fruit pine nuts, and maritime pine nuts, are the seeds of Pinus koraiensis and other plants of the Pinaceae family. They are one of the common nuts and are rich in fat, protein, carbohydrates, etc. They are an important Chinese medicine. Long-term consumption can strengthen the body and mind, moisturize the skin, and prolong life. They also have high therapeutic value. Screening is an important process in the production of pine nuts.

[0003] The publication number in the existing public technology is: CN219880599U. A finished pine nut wind screening machine includes a screen box, the interior of the screen box is hinged with a first screen and a second screen through a pin shaft, and a driving mechanism for the first screen and the second screen to swing back and forth is provided directly below the first screen. The first screen is used for the first screening to screen out large particles of impurities, and the screened pine nuts fall on the second screen for re-screening. During the falling process of the pine nuts, the fan blades are driven to rotate to blow the falling pine nuts, and the lighter impurities in the pine nuts are blown out of the interior of the screen box through the blocking net, and fall into the interior of the lower box for collection, and then screened again through the second screen, which greatly improves the screening effect, and drives the first screen and the second screen to swing back and forth during the screening process through the driving mechanism, which accelerates the screening efficiency of the first screen and the second screen, and prevents impurity particles from blocking the first screen and the second screen.

[0004] The existing technology has the following problems:

[0005] Although the pine nuts can be screened through multiple groups of screens, the flat screening process is inefficient and it is easy for substandard pine nuts to remain on the surface of the other pine nuts and slide into the collection box together with the other pine nuts, affecting the overall screening quality. In addition, when removing impurities on the surface of the pine nuts, the effect of simple wind blowing is very limited. The pine nuts in the center cannot be fully and effectively blown, which in turn affects the overall impurity removal effect, resulting in a significant reduction in the overall quality of the device.

[0006] To this end, we proposed a new type of impurity removal and screening device for pine nut processing to solve the above-mentioned drawbacks. Utility Model Content

[0007] The utility model aims to solve the shortcomings in the prior art and proposes a novel impurity removal and screening device for pine nut processing.

[0009] Preferably, a feed pipe is installed through the interior of the screening cylinder, and a sealing door is installed at a side position of the surface of the screening cylinder.

[0010] Preferably, a filter element and a dust collector are provided inside the impurity box.

[0011] Preferably, a blower is fixedly installed at one side of the top of the processing box, and one end of the blower is connected to the air injection pipe.

[0012] Preferably, a plurality of groups of supporting legs are symmetrically installed on both sides of the bottom of the processing box.

[0013] Preferably, a dust collecting cover is installed around the outer periphery of the exhaust hood located at the bottom end of the processing box.

[0014] Preferably, a plurality of groups of screens are installed around the surface of the screening cylinder, and the aperture sizes of the screens gradually decrease.

[0015] Preferably, the cleaning plate is an L-shaped structure.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) The utility model adopts a brush, an exhaust hood and an air outlet. During operation, the reverse operation of the first brake motor and the second brake motor can drive the screen drum and the blowing tube to rotate in opposite directions. In this way, when the screen drum rotates, the pine nuts moving inside can have a larger contact with the cleaning plate on the surface of the blowing tube, so that the brush on the surface can wipe the surface of the pine nuts, thereby removing impurities on the surface. The air outlet on the surface of the blowing tube can guide the gas ejected from the air jet hole. The impurities on the surface of the pine nuts can be further removed by the impact of the air flow. When the air outlet is ejected, the exhaust hood below can simultaneously suck the inside. In this way, the impurities blown and scraped off can be promptly guided out by the exhaust hood, avoiding the secondary attachment of impurities and improving the impurity removal effect on the pine nuts. The utility model has the advantages of multiple impurity removal and screening and good impurity removal effect.

[0018] (2) The utility model adopts a screening cylinder. When working, personnel can add the pine nuts to be processed into the inner part of the screening cylinder up to the center through the feed pipe. The pine nuts can be continuously rotated inside the screening cylinder and screened by the different sieve apertures on the surface. Compared with the traditional flat-plate screening structure, the screening efficiency can be significantly improved, and it can be ensured that the pine nuts can be fully screened, avoiding that some pine nuts are directly discharged without being screened, thereby improving the classification quality of the pine nuts after screening and facilitating better subsequent processing.
