[0002] Coke is a kind of solid fuel, obtained by dry distillation of coal under high temperature conditions. Its main components are fixed carbon, followed by ash, and it contains very little volatile matter and sulfur. It is silver-gray with a metallic luster. It is hard and porous.
[0003] During coke production, the coke is generally crushed and screened according to usage requirements, so that coke fragments of suitable size can be collected.
[0004] After the coke is crushed, a large amount of coke dust will be produced. When the coke is screened, a large amount of coke dust will float around the device, which will easily affect the health of the operators around the device. Utility Model Content
[0005] The purpose of the utility model is to provide a coke screening device in order to solve the above-mentioned problem.
[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:
[0007] A coke screening device comprises a stand, a material receiving mechanism is installed at the lower end of the stand plate surface, and a screening mechanism with a dust cleaning effect;
[0008] The screening mechanism includes four columns, which are respectively fixed at the four corners of the upper end of the frame. The upper ends of the columns are slidably connected to a sliding top plate, and a lower extension frame is fixed to the lower end in the middle of the sliding top plate. Vibration motors are installed at the front and rear ends of the lower extension frame. A fine screen frame is placed inside the lower extension frame, and a coarse screen frame is arranged above the fine screen frame. A double-rod bracket is arranged at one end of the lower extension frame corresponding to the position of the coarse screen frame and the fine screen frame, and the brackets of the double-rod bracket pass through the lower extension frame and the corresponding coarse screen frame and fine screen frame. Pull handles are fixed on the upper ends of the coarse screen frame and the fine screen frame, and convex strips are fixed on both ends of the fine screen frame. Two dust extractors are installed on both ends of the lower extension frame, and dust filter bags are fixed on the output ends of the dust extractors.
[0009] Preferably, one end of the two insertion rods of the double-rod insertion rack is threadedly connected with a nut, and the other end of the double-rod insertion rack is provided with a square groove.
[0010] Preferably, the two convex strips are in a right-angle trapezoidal shape, and the inclined surfaces of the two convex strips are arranged corresponding to the direction of the fine screen frame filter.
[0011] Preferably: the screening mechanism also includes a flap, which is rotatably connected to the upper end of the sliding top plate, and locking bolts are provided at the four corners of the flap, and the locking bolts penetrate the flap and are threadedly connected to the sliding top plate, and a sealing cover is installed at the upper end opening of the flap.
[0012] Preferably, a rubber layer is provided on the inner wall of the cover, and embedded handles are provided on both ends of the cover.
[0013] Preferably, the material receiving mechanism comprises a square hole, which is arranged in the middle of the platform plate surface, a slide plate is slidably connected inside the platform plate surface, and a material receiving frame is fixed at the lower end of the slide plate.
[0014] The beneficial effects compared with the prior art are as follows:
[0015] When the device is in operation, the sliding top plate is slidably connected to the four columns. When the vibration motor is started, the sliding top plate and the structure inside the lower extension frame can vibrate, so that the coarse screen frame and the fine screen frame can screen the coke. When the two vibration motors are started, the dust extractors at both ends of the lower extension frame are started at the same time. In this way, the dust generated during screening can be sucked, thereby reducing the dust generated by the device during operation. After the dust extractor is started, some smaller cokes will change their original falling trajectory due to the suction force generated by the dust extractor. At this time, due to the gravity of the coke itself and the setting of the convex strips, these smaller cokes will be blocked by the convex strips, and then they will slide through the inclined surface of the convex strips into the fine screen frame for screening. In this way, some smaller cokes can be prevented from being sucked into the dust filter bag along with the dust. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figure 1-Figure 5 As shown, a screening device for coke comprises a stand 1, a material receiving mechanism is installed at the lower end of the plate surface of the stand 1, and also comprises a screening mechanism with a dust cleaning effect.
[0028] Two base frames 11 are fixed at the lower end of the stand 1 , and a plurality of fixing bolts 12 are arranged in the middle of the base frames 11 ; the device can be fixed to a suitable position by the fixing bolts 12 .
[0029] The screening mechanism includes four columns 2, which are respectively fixed at the four corners of the upper end of the stand 1. The upper ends of the columns 2 are slidably connected with a sliding top plate 21, and a lower extension frame 22 is fixed at the lower end in the middle of the sliding top plate 21. A vibration motor 23 is installed at the front and rear ends of the lower extension frame 22. The upper end of the sliding top plate 21 is rotatably connected with a flap 24, and locking bolts 25 are arranged at the four corners of the flap 24, and the locking bolts 25 penetrate the flap 24 and are threadedly connected to the sliding top plate 21. A cover 26 is installed at the upper end opening of the flap 24, and the inner wall of the cover 26 is provided with a rubber layer, and the cover 26 is provided with a rubber layer. Embedded handles are provided at both ends, a fine screen frame 28 is placed inside the lower extension frame 22, a coarse screen frame 27 is provided above the fine screen frame 28, a double-rod insertion frame 29 is provided at one end of the lower extension frame 22 corresponding to the coarse screen frame 27 and the fine screen frame 28, one end of the two insertion rods of the double-rod insertion frame 29 are threadedly connected with nuts, the other end of the double-rod insertion frame 29 is provided with a square groove, and the insertion rods of the double-rod insertion frame 29 pass through the lower extension frame 22 and the corresponding coarse screen frame 27 and fine screen frame 28, the upper ends of the coarse screen frame 27 and the fine screen frame 28 are fixed with pull handles 210, and the two ends of the fine screen frame 28 are fixed with convex strips 211. The convex strips 211 are in a right-angled trapezoid, and the inclined surfaces of the two convex strips 211 are set in the direction of the filter screen of the fine screen frame 28. Two dust extractors 212 are installed at both ends of the lower extension frame 22, and dust filter bags 213 are fixed at the output ends of the dust extractors 212. When the device is in operation, the sliding top plate 21 is connected to the four columns 2 through sliding. When the vibration motor 23 is started, the sliding top plate 21 and the internal structure of the lower extension frame 22 can vibrate, so that the coarse screen frame 27 and the fine screen frame 28 can screen the coke. When the two vibration motors 23 are started, the dust extractors at both ends of the lower extension frame 22 are started. 212. In this way, the dust generated during screening can be sucked out, thereby reducing the dust generated by the device during operation. After the dust extractor 212 is started, some smaller cokes will change their original falling trajectory due to the suction force generated by the dust extractor 212. At this time, due to the gravity of the coke itself and the setting of the convex strip 211, these smaller cokes will be blocked by the convex strip 211, and then will slide through the inclined surface of the convex strip 211 to the fine screen frame 28 for screening. In this way, some smaller cokes can be prevented from being sucked into the dust filter bag 213 along with the dust.
[0030] The material receiving mechanism includes a square hole 3, which is opened in the middle of the plate surface of the stand 1. A slide plate 31 is slidably connected inside the plate surface of the stand 1, and a material receiving frame 32 is fixed at the lower end of the slide plate 31. The opening of the square hole 3 can make the screened coke fall into the material receiving frame 32. Through the sliding connection between the slide plate 31 and the stand 1, when the coke in the material receiving frame 32 is full, the slide plate 31 can be pulled out, thereby facilitating the removal of the coke in the material receiving frame 32.
[0031] Working principle: Before the device is operated, first hold the embedded handles at both ends of the cover 26 to remove the cover 26, then pour the coke to be screened into the device from the through hole in the middle of the flap 24, and then cover the cover 26. After the preparation work is completed, start the two vibration motors 23 and all the dust extractors 212. Through the sliding connection between the sliding top plate 21 and the four columns 2, when the vibration motor 23 is started, the sliding top plate 21 can vibrate, thereby causing the structure inside the lower extension frame 22 to vibrate. When the dust extractor 212 is started, suction is generated at both ends of the lower extension frame 22, so that the dust generated during screening can be sucked, thereby reducing the dust generated during the operation of the device, and when the dust extractor is started, the dust can be sucked out. After 212 is started, some smaller cokes will change their original falling trajectory due to the suction force generated by the dust extractor 212. At this time, due to the gravity of the coke itself and the setting of the convex strip 211, these smaller cokes will be blocked by the convex strip 211, and then will slide through the inclined surface of the convex strip 211 to the fine screen frame 28 for screening. This can prevent some smaller cokes from being sucked into the dust filter bag 213 along with the dust. Finally, the screened coke will fall into the receiving frame 32 through the square hole 3. After the coke in the receiving frame 32 is full, the slide plate 31 is slidably connected to the stand 1, and the slide plate 31 is pulled to pull the receiving frame 32 out to facilitate the removal of the coke in the receiving frame 32.
