Dezavantajul acestei soluţii constă în dificultatea lucrărilor de deservire la exploatarea dispozitivului. De asemenea, dispozitivul este complicat în construcţie, are o înălţime mare şi este costisitor. The disadvantage of this solution is the difficulty of maintenance work when operating the device. Also, the device is complicated in construction, has a large height and is expensive.

Problema pe care o rezolvă invenţia constă în simplificarea deservirii tehnice a ciuruitorului şi micşorarea preţului acestuia. The problem that the invention solves consists in simplifying the technical maintenance of the sieve and reducing its price.

Ciuruitorul pentru separarea peletelor, conform invenţiei, înlătură dezavantajele menţionate mai sus prin aceea că conţine un cadru, pe partea de jos a căruia este montat un buncăr cu o gură de evacuare a prafului şi rămăşiţelor de pelete. În interiorul cadrului este amplasată o sită înclinată, formată dintr-o cutie şi o plasă, care este fixată de cadru, din părţile de sus şi de jos ale ei, prin intermediul unor benzi elastice, unite cu suspensii elastice, de care este suspendată. Capetele de sus ale suspensiilor elastice sunt fixate de cadru prin intermediul unor nituri, iar cele de jos sunt fixate de pereţii sitei înclinate prin intermediul unor suporturi, montate mai jos de fundul sitei înclinate. Suspensiile elastice din partea de sus a sitei înclinate sunt executate mai lungi decât suspensiile din partea de jos a acesteia. Pe cadru, în partea de sus a sitei înclinate este fixat un motor-vibrator, care este unit cu peretele sitei înclinate, iar în partea de jos a ei este montat un buncăr pentru captarea peletelor ciuruite. Orificiile plasei sunt executate dreptunghiulare, latura mai mare a lor fiind amplasată perpendicular planului de înclinare a sitei. The pellet separator according to the invention eliminates the above-mentioned disadvantages by containing a frame, on the lower part of which a hopper with a discharge opening for dust and pellet residues is mounted. Inside the frame is placed an inclined screen, consisting of a box and a mesh, which is fixed to the frame, from its upper and lower parts, by means of elastic bands, joined with elastic suspensions, from which it is suspended. The upper ends of the elastic suspensions are fixed to the frame by means of rivets, and the lower ones are fixed to the walls of the inclined screen by means of supports, mounted below the bottom of the inclined screen. The elastic suspensions at the top of the inclined screen are made longer than the suspensions at the bottom of it. On the frame, at the top of the inclined screen, a vibrator motor is fixed, which is connected to the wall of the inclined screen, and at the bottom of it, a hopper is mounted to capture the sifted pellets. The mesh openings are made rectangular, their larger side being located perpendicular to the screen's inclination plane.

O particularitate a invenţiei este acţionarea ciuruitorului, efectuată de motorul-vibrator, care simplifică dispozitivul şi reduce preţul acestuia. A particularity of the invention is the operation of the sieve, performed by the vibrator motor, which simplifies the device and reduces its price.

Rezultatul invenţiei constă în simplificarea deservirii tehnice a ciuruitorului, sporirea calităţii de separare a peletelor de praf şi rămăşiţele de pelete. The result of the invention consists in simplifying the technical maintenance of the screener, increasing the quality of separation of pellets from dust and pellet remains.

Invenţia se explică prin desenul din figură, în care este reprezentată schema ciuruitorului pentru separarea peletelor. The invention is explained by the drawing in the figure, which represents the scheme of the screener for separating pellets.

Ciuruitorul pentru separarea peletelor conţine un cadru 1, pe partea de jos a căruia este montat un buncăr 2 cu o gură 3 de evacuare a prafului şi rămăşiţelor de pelete. În interiorul cadrului 1 este amplasată o sită înclinată 4, formată dintr-o cutie 8 şi o plasă 5. Orificiile plasei 5 sunt executate dreptunghiulare, latura mai mare a lor fiind amplasată perpendicular planului de înclinare a sitei 4. Sita înclinată 4 este fixată de cadrul 1 din părţile de sus şi de jos ale ei, prin intermediul unor benzi elastice 11, 12, unite cu suspensiile elastice 6, 7, de care este suspendată. Capetele de sus ale suspensiilor elastice 6, 7 sunt fixate de cadrul 1 prin intermediul unor nituri 13, 14, iar cele de jos sunt fixate de pereţii sitei înclinate 4 prin intermediul unor suporturi 15, 16, montate mai jos de fundul sitei înclinate 4. Suspensiile elastice 6 din partea de sus a sitei înclinate 4 sunt executate mai lungi decât suspensiile 7 din partea de jos a acesteia. Pe cadrul 1, în partea de sus a sitei înclinate 4 este fixat un motor-vibrator 9, care este unit cu peretele sitei înclinate 4. În partea de jos a sitei înclinate 4 este montat un buncăr 10 pentru captarea peletelor ciuruite. Buncărul 2 este unit printr-o conductă 17 cu un ventilator 18 pentru aspiraţia prafului. The pellet separator comprises a frame 1, on the lower part of which is mounted a hopper 2 with a mouth 3 for discharging dust and pellet remains. Inside the frame 1 is placed an inclined sieve 4, consisting of a box 8 and a mesh 5. The holes of the mesh 5 are rectangular, their larger side being located perpendicular to the plane of inclination of the sieve 4. The inclined sieve 4 is fixed to the frame 1 from its upper and lower parts, by means of elastic bands 11, 12, joined to the elastic suspensions 6, 7, from which it is suspended. The upper ends of the elastic suspensions 6, 7 are fixed to the frame 1 by means of rivets 13, 14, and the lower ones are fixed to the walls of the inclined screen 4 by means of supports 15, 16, mounted below the bottom of the inclined screen 4. The elastic suspensions 6 at the top of the inclined screen 4 are made longer than the suspensions 7 at the bottom. On the frame 1, at the top of the inclined screen 4, a vibrator motor 9 is fixed, which is connected to the wall of the inclined screen 4. At the bottom of the inclined screen 4, a hopper 10 is mounted for capturing the sifted pellets. The hopper 2 is connected via a pipe 17 to a fan 18 for dust suction.

Ciuruitorul pentru separarea peletelor funcţionează în felul următor. The pellet separator works as follows.

Peletele deja răcite se introduc în partea de sus a sitei înclinate 4, pentru aceasta ciuruitorul se amplasează în modul cuvenit faţă de gura de evacuare a peletelor din răcitor (în figură nu este arătat). Peletele trebuie să fie amplasate uniform pe toată lăţimea sitei înclinate. Se porneşte motorul-vibrator 9 şi, datorită faptului că lungimea suspensiilor elastice 6, 7 este diferită şi linia de acţionare a motorului-vibrator 9 nu coincide cu centrul de greutate al ciuruitorului, oscilaţiile create nasc forţe, care saltă peletele de pe sita înclinată 4 şi le mişcă în jos spre buncărul 10 pentru captarea peletelor ciuruite. O astfel de mişcare asigură separarea calitativă a peletelor ciuruite. Viteza de mişcare şi gradul de săltare a peletelor depind şi de rotaţiile motorului-vibrator 9, care se reglează utilizând un schimbător de frecvenţă. The already cooled pellets are introduced into the upper part of the inclined screen 4, for this the screen is placed in the appropriate way with respect to the outlet of the pellets from the cooler (not shown in the figure). The pellets must be placed evenly over the entire width of the inclined screen. The vibrating motor 9 is turned on and, due to the fact that the length of the elastic suspensions 6, 7 is different and the line of action of the vibrating motor 9 does not coincide with the center of gravity of the screen, the created oscillations give rise to forces that jump the pellets off the inclined screen 4 and move them down towards the hopper 10 for capturing the screened pellets. Such a movement ensures the qualitative separation of the screened pellets. The speed of movement and the degree of jumping of the pellets also depend on the rotations of the vibrating motor 9, which is adjusted using a frequency converter.

Datorită faptului că suspensiile elastice 6, 7 sunt destul de lungi, oscilaţiile provocate de motorul-vibrator 9 practic nu se transmit cadrului 1, ceea ce se reflectă pozitiv asupra fiabilităţii ciuruitorului. Due to the fact that the elastic suspensions 6, 7 are quite long, the oscillations caused by the vibrating motor 9 are practically not transmitted to the frame 1, which has a positive effect on the reliability of the screener.

Testările au demonstrat că un astfel de ciuruitor, acţionat de un motor-vibrator, separă mai eficient peletele de praf şi rămăşiţe comparativ cu un ciuruitor acţionat de un mecanism cu excentric. Tests have shown that such a screener, driven by a vibratory motor, separates pellets from dust and debris more efficiently compared to a screener driven by an eccentric mechanism.

Avantajele ciuruitorului constau în aceea că s-a simplificat construcţia ciuruitorului şi deservirea tehnică a acestuia, s-a redus preţul şi s-a majorat calitatea de separare. The advantages of the screener are that the screener's construction and technical maintenance have been simplified, the price has been reduced, and the separation quality has been increased.
