Description

Technical Field

[0001] This utility model relates to the field of dry coal preparation machine technology, specifically to an energy-saving sorting bed surface for a dry coal preparation machine. Background Technology

[0002] Coal preparation machines are mainly used to separate useful minerals (such as clean coal and middlings) from useless minerals (such as gangue) in raw coal to improve the quality and utilization efficiency of coal. The working principle of coal preparation machines is based on the difference in density between coal and gangue, and separation is achieved through various technologies such as flotation, gravity separation, and magnetic separation. Dry coal preparation machines are a type of coal preparation machine with a series of advantages such as not requiring water, simple process, low investment, low production cost, high recovery rate, low energy consumption, and low environmental pollution.

[0003] Chinese Utility Model Patent Publication No. CN215197534U discloses an airflow separator. In this airflow separator, the vibration direction of the separation bed in the multi-product material separator is biased towards the feed inlet. This not only allows for the rapid separation of clean coal and gangue in raw coal materials with low gangue content, but also allows the gangue to accumulate on the separation bed before being discharged, significantly increasing the gangue content in the material discharged from the gangue outlet. However, although this airflow separator can separate clean coal from gangue, the airflow can still act on the gangue layer at the front end of the separation plate, resulting in high energy consumption. Furthermore, the lack of a separation plate installation structure makes it inconvenient to replace the separation plate with corresponding ventilation holes when dealing with different working conditions, resulting in low adaptability, poor practicality, and difficulty in widespread use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an energy-saving sorting bed for a dry coal preparation machine. It can effectively solve the problems in the prior art that although it can separate clean coal from gangue, the wind force can still act on the gangue layer at the front end of the sorting plate, resulting in high energy consumption. In addition, the prior art does not have an installation structure for the sorting plate, and it is not convenient to replace the sorting plate with ventilation holes of corresponding size when dealing with different working conditions. It has low adaptability, poor practicality, and is not convenient for widespread use.

[0005] The technical solution adopted by this utility model is: an energy-saving sorting bed surface for a dry coal preparation machine, including a box, a sorting box, a top cover and a mounting frame. The mounting frame has a mounting groove and a threaded hole at one end near the top cover. A sorting plate is provided at one end of the mounting frame near the top cover. A ventilation hole and a threaded hole are provided on the side of the sorting plate near the top cover. A bolt for fixing the sorting plate is threadedly connected to the side of the sorting plate near the top cover. A guide sleeve is fixedly installed on the side of the mounting frame away from the sorting plate. A wind box and a gangue discharge hopper are fixedly installed inside the box. A fan is fixedly installed inside the wind box. A connecting component is provided between the wind box and the connecting component. A gangue discharge pipe is provided at the bottom of the gangue discharge hopper.

[0006] The connecting assembly includes a fixing block, a second mounting groove, a sealing ring, a positioning groove, a sliding groove, a limiting block, a buckle, a positioning sleeve, a limiting groove, and a slot. The fixing block has a second mounting groove on its outer side, and a sealing ring is provided inside the second mounting groove. The side of the air box near the guide sleeve has a positioning groove and a sliding groove. The sliding groove is slidably connected to the limiting block. A buckle is fixedly installed on the outer side of the limiting block. The end of the guide sleeve near the air box is fixedly installed with a positioning sleeve. The outer side of the positioning sleeve has a limiting groove and a slot.

[0007] Preferably, the sorting plate and the mounting groove are connected by an insertion, and the bolt extends through the threaded hole to the interior of the threaded hole.

[0008] Using the above technical solution, the workers insert the sorting plate into the interior of the first mounting slot, and then extend the bolt through the second threaded hole into the interior of the first threaded hole, which can realize the quick installation of the sorting plate. The sorting plate with different ventilation holes can be replaced according to different working conditions, and the adaptability is high.

[0009] Preferably, a mounting frame is fixedly installed at the end of the top cover away from the sorting box, a vibration motor is fixedly installed on the outside of the mounting frame, a clean coal hopper is fixedly installed on the outside of the sorting box, a feed inlet is opened on the side of the top cover away from the sorting box, and three identical sorting plates, blowers, gangue hoppers and gangue discharge pipes are provided, with the three sorting plates, blowers, gangue hoppers and gangue discharge pipes distributed at equal intervals.

[0010] With the above technical solution, when raw coal enters the sorting box through the feed inlet and falls onto the sorting plate, the staff then starts the blower and vibrating motor. Under the combined action of the blower and vibrating motor, the raw coal causes the gangue to move towards the gangue discharge hopper. The gangue then falls into the gangue discharge hopper and is finally discharged through it. At the same time, the clean coal is discharged through the clean coal discharge hopper. Through the design of three sorting plates, blowers, gangue discharge hoppers, and gangue discharge pipes, the gangue sorting efficiency is improved, allowing more raw coal to be sorted and more gangue to be discharged simultaneously, resulting in high work efficiency.

[0011] Preferably, the front end of the sorting plate is a layer of gangue, and no ventilation holes are provided at the front end of the sorting plate.

[0012] By employing the above technical solution, the design of not opening ventilation holes in the gangue layer at the front end of the sorting plate can reduce the energy consumption of the blower. At the same time, since the gangue layer at the front end of the sorting plate is not affected by wind, it can quickly remove gangue and improve work efficiency.

[0013] Preferably, the fixing block and the positioning sleeve are installed by insertion, and the positioning sleeve and the positioning groove are installed by insertion.

[0014] Using the above technical solution, the staff inserts the fixing block into the inside of the positioning sleeve, and at the same time inserts the positioning sleeve into the inside of the positioning groove, which can realize the rapid positioning of the guide sleeve and the air box.

[0015] Preferably, the sliding groove, the limiting groove, and the slot are connected, the limiting block is adapted to the limiting groove, the buckle is adapted to the slot, and the guide sleeve is a rubber sleeve.

[0016] With the above technical solution, after the guide sleeve and the air box are quickly positioned, the operator slides the limiting block into the limiting groove. When the buckle contacts the positioning sleeve, the buckle deforms. When the limiting block is completely submerged in the limiting groove, the buckle returns to its original shape, allowing the buckle to engage with the groove. This enables the guide sleeve and the air box to be quickly connected. The design of the guide sleeve allows the airflow generated by the fan to pass through the ventilation hole, preventing the airflow from flowing elsewhere, reducing energy waste, and achieving energy saving.

[0017] Preferably, the sealing ring is a rubber ring, and three identical sealing rings are provided, with the three sealing rings distributed at equal intervals.

[0018] The above technical solution, due to the good sealing performance of the rubber ring, prevents the airflow generated by the fan from leaking through the connection between the guide sleeve and the air box, thus avoiding energy waste and further improving the energy-saving effect. It is highly practical.

[0019] Compared with the prior art, this utility model provides an energy-saving sorting bed surface for a dry coal preparation machine, which has the following beneficial effects:

[0020] 1. The energy-saving sorting bed of this dry coal preparation machine can be quickly installed by matching the sorting plate with the mounting slot one and bolts, and threaded hole two with threaded hole one. It can replace the sorting plate with different ventilation holes according to different working conditions, and has high adaptability. Through the design of the connecting components, the guide sleeve and the air box can be quickly connected. Through the design of the guide sleeve, the airflow generated by the fan can pass through the ventilation holes fully, avoiding the airflow flowing to other places, reducing energy waste, and achieving the effect of energy saving.

[0021] 2. The energy-saving sorting bed of this dry coal preparation machine reduces the energy consumption of the fan by designing that the gangue layer at the front end of the sorting plate does not have ventilation holes. At the same time, since the gangue layer at the front end of the sorting plate is not affected by wind, it can quickly remove gangue, improving work efficiency. Because the rubber ring has good sealing performance, the design of the sealing ring prevents the airflow generated by the fan from leaking through the connection between the guide sleeve and the air box, thus avoiding energy waste and further improving the energy-saving effect. It is highly practical. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1: As Figure 1-7As shown, the present invention provides an energy-saving sorting bed for a dry coal preparation machine, comprising a housing 1, a sorting box 2, a top cover 3, and a mounting frame 6. The mounting frame 6 has a mounting groove 7 and a threaded hole 8 at one end near the top cover 3. A sorting plate 9 is provided at one end of the mounting frame 6 near the top cover 3. A ventilation hole 10 and a threaded hole 11 are provided on the side of the sorting plate 9 near the top cover 3. A bolt 12 for fixing the sorting plate 9 is threadedly connected to the side of the sorting plate 9 near the top cover 3. A guide sleeve 13 is fixedly installed on the side of the mounting frame 6 away from the sorting plate 9. A wind box 14 and a gangue discharge hopper 17 are fixedly installed inside the housing 1. A fan 15 is fixedly installed inside the wind box 14. A connecting component 16 is provided between the wind box 14 and the connecting component 16. A gangue discharge pipe 18 is provided at the bottom end of the gangue discharge hopper 17.

[0032] The connecting component 16 includes a fixing block 1601, a second mounting groove 1602, a sealing ring 1603, a positioning groove 1604, a sliding groove 1605, a limiting block 1606, a buckle 1607, a positioning sleeve 1608, a limiting groove 1609, and a slot 1610. The fixing block 1601 has a second mounting groove 1602 on its outer side, and the sealing ring 1603 is provided inside the second mounting groove 1602. The air box 14 has a positioning groove 1604 and a sliding groove 1605 on its side near the guide sleeve 13. The limiting block 1606 is slidably connected inside the sliding groove 1605. The buckle 1607 is fixedly installed on the outer side of the limiting block 1606. The positioning sleeve 1608 is fixedly installed on the end of the guide sleeve 13 near the air box 14. The positioning sleeve 1608 has a limiting groove 1609 and a slot 1610 on its outer side.

[0033] Specifically, the sorting plate 9 and the mounting slot 7 are connected by an insertion joint, with bolt 12 extending through threaded hole 11 into threaded hole 8. The advantage is that workers can quickly install the sorting plate 9 by inserting it into the mounting slot 7 and then extending bolt 12 through threaded hole 11 into threaded hole 8. Furthermore, the sorting plate 9 with different ventilation holes 10 can be replaced according to different working conditions, demonstrating high adaptability.

[0034] Specifically, a mounting frame 4 is fixedly installed at the end of the top cover 3 away from the sorting box 2, a vibration motor 5 is fixedly installed on the outside of the mounting frame 4, a clean coal feeding hopper 19 is fixedly installed on the outside of the sorting box 2, and a feed inlet 20 is opened on the side of the top cover 3 away from the sorting box 2. There are three identical sorting plates 9, blowers 15, gangue feeding hoppers 17 and gangue feeding pipes 18, and the three sorting plates 9, blowers 15, gangue feeding hoppers 17 and gangue feeding pipes 18 are distributed at equal intervals. The advantage is that when raw coal enters the sorting box 2 through the feed inlet 20 and falls onto the sorting plate 9, the staff then starts the blower 15 and the vibrating motor 5. Under the combined action of the blower 15 and the vibrating motor 5, the raw coal causes the gangue to move towards the gangue discharge hopper 17. The gangue then falls into the gangue discharge hopper 17 and is finally discharged through the gangue discharge hopper 17. At the same time, the clean coal is discharged through the clean coal discharge hopper 19. Through the design of the three sorting plates 9, the blower 15, the gangue discharge hopper 17 and the gangue discharge pipe 18, the gangue sorting efficiency is improved. More raw coal can be sorted and more gangue can be discharged at the same time, resulting in high work efficiency.

[0035] Specifically, the front end of the sorting plate 9 is a layer of gangue, and no ventilation holes 10 are opened at the front end of the sorting plate 9. The advantage is that by not opening ventilation holes 10 in the gangue layer at the front end of the sorting plate 9, the energy consumption of the blower 15 can be reduced. At the same time, since the gangue layer at the front end of the sorting plate 9 is not affected by wind, gangue can be quickly discharged, improving work efficiency.

[0036] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0037] Specifically, the fixing block 1601 and the positioning sleeve 1608 are installed by insertion, and the positioning sleeve 1608 and the positioning groove 1604 are installed by insertion. The advantage is that when the operator inserts the fixing block 1601 into the interior of the positioning sleeve 1608 and simultaneously inserts the positioning sleeve 1608 into the interior of the positioning groove 1604, the flow guide sleeve 13 and the air box 14 can be quickly positioned.

[0038] Specifically, the slide 1605, the limiting groove 1609, and the locking groove 1610 are interconnected. The limiting block 1606 is adapted to the limiting groove 1609, and the buckle 1607 is adapted to the locking groove 1610. The guide sleeve 13 is a rubber sleeve. The advantage is that after quickly positioning the guide sleeve 13 and the air box 14, the operator slides the limiting block 1606 into the limiting groove 1609. When the buckle 1607 contacts the positioning sleeve 1608, the buckle 1607 deforms. When the limiting block 1606 is completely submerged in the limiting groove 1609, the buckle 1607 returns to its original shape, allowing it to engage with the locking groove 1610. This enables a quick connection between the guide sleeve 13 and the air box 14. The design of the guide sleeve 13 ensures that the airflow generated by the fan 15 passes fully through the ventilation hole 10, preventing airflow from flowing elsewhere, reducing energy waste, and achieving energy-saving effects.

[0039] Specifically, the sealing ring 1603 is a rubber ring, and three identical sealing rings 1603 are provided, distributed at equal intervals. The advantage is that, due to the good sealing performance of the rubber ring, the design of the sealing ring 1603 prevents airflow generated by the fan 15 from leaking through the connection between the guide sleeve 13 and the air box 14, thus avoiding energy waste and further improving energy-saving performance. It is highly practical.

[0040] Working principle: During installation, the operator inserts the sorting plate 9 into the mounting slot 7, and then inserts the bolt 12 through the threaded hole 11 to the threaded hole 8, enabling rapid installation of the sorting plate 9. The sorting plate 9 with different ventilation holes 10 can be replaced according to different working conditions, exhibiting high adaptability. Subsequently, the operator inserts the fixing block 1601 into the positioning sleeve 1608, and simultaneously inserts the positioning sleeve 1608 into the positioning slot 1604, enabling rapid positioning of the guide sleeve 13 and the air box 14. The guide sleeve 13 and the air box 14 are then quickly... After quick positioning, the operator slides the limiting block 1606 into the limiting groove 1609. When the buckle 1607 contacts the positioning sleeve 1608, the buckle 1607 deforms. When the limiting block 1606 is completely submerged in the limiting groove 1609, the buckle 1607 returns to its original shape, allowing the buckle 1607 to engage with the slot 1610, thus enabling quick connection between the guide sleeve 13 and the air box 14. In use, the operator first connects the external power supply. Then, when the raw coal enters the sorting box 2 through the feed inlet 20 and falls onto the sorting plate 9, the operator starts the process. The blower 15 and vibrating motor 5 work together to move the raw coal and gangue towards the gangue discharge hopper 17. The gangue then falls into the hopper and is discharged through it. Simultaneously, clean coal is discharged through the clean coal discharge hopper 19. The design of the three sorting plates 9, blower 15, gangue discharge hopper 17, and gangue discharge pipe 18 improves the gangue sorting efficiency, allowing for the simultaneous sorting and discharge of more raw coal and gangue, resulting in high working efficiency. The design also avoids opening ventilation holes 10 in the gangue layer at the front end of the sorting plates 9. This design reduces the energy consumption of the blower 15. Simultaneously, since the gangue layer at the front end of the sorting plate 9 is unaffected by wind, it allows for rapid gangue removal, improving work efficiency. The design of the guide sleeve 13 ensures that the airflow generated by the blower 15 passes fully through the ventilation holes 10, preventing airflow from flowing elsewhere, reducing energy waste, and achieving energy-saving effects. Because the rubber ring has good sealing properties, the design of the sealing ring 1603 prevents the airflow generated by the blower 15 from leaking through the connection between the guide sleeve 13 and the air box 14, thus avoiding energy waste and further improving the energy-saving effect. It is highly practical.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
