Description

Technical Field

[0001] This utility model belongs to the field of mineral and metallurgical technology, and specifically relates to a small-angle feeding chute. Background Technology

[0002] The bulk material collection conveyor of the annular cooler and the belt transfer equipment are connected by a tubular screw conveyor, which transports finished bulk pellets. During transport, these pellets are prone to getting stuck in the gaps, causing conveyor overload and jamming. Furthermore, this equipment is located in the pit at the tail of the belt conveyor, installed 2 meters above the pit floor, with the top of the tubular screw conveyor 260mm from the top platform and the motor tail close to the pit wall. If the tubular conveyor malfunctions, repairs are difficult due to the confined space. A full hopper in the annular cooler directly affects normal production. Abnormal production can lead to the conveyor belt burning due to accumulated bulk material inside the annular cooler. Utility Model Content

[0003] To address the problems of existing technologies, the purpose of this utility model is to provide a small-angle discharge chute. By installing a vibrating motor and a level gauge on the chute, bulk material pellets can be shaken off at any time. Simultaneously, the bulk material in the chute can be monitored, preventing the conveyor belt of the annular cooler from burning out when the bulk material hopper is full. To achieve the above objectives, this utility model provides the following technical solution: A small-angle discharge chute includes a platform support beam. Two sets of suspension springs are installed below the platform support beam. A lower chute is installed at the lower end of the suspension springs. The suspension springs are respectively installed on both sides of the lower chute. A vibration motor is installed on the outer side of the lower chute. An upper chute is provided at the upper end of the lower chute. A dust cover is provided on the upper chute. A feed inlet is provided on one side of the upper chute. A frame is provided on the platform support beam. The frame is located around the upper chute. The upper chute is provided with several brackets. The brackets are matched and connected to the frame. A shock absorption device is provided between the brackets and the frame.

[0004] Preferably, the shock absorption device includes an upper limit groove and a lower limit groove. The upper limit groove is disposed on the bracket, and the lower limit groove is disposed on the frame. An upper limit pin is disposed on the upper limit groove, and a lower limit pin is disposed on the lower limit groove. A shock absorption block is disposed between the upper limit groove and the lower limit groove, and the shock absorption block is installed between the upper limit groove and the lower limit groove via the upper limit pin and the lower limit pin.

[0005] Preferably, the lower end of the lower chute has a belt dust collection hood, and a belt conveyor is provided below the belt dust collection hood.

[0006] Preferably, the upper chute and the lower chute are connected by a flange.

[0007] Preferably, a level gauge is installed on the inner side of the lower chute, and the lower chute is inclined at an angle of 25°.

[0008] The beneficial effects of this utility model are as follows: 1. The platform support beam of the small-angle discharge chute of this utility model is equipped with a suspension spring. A vibrating motor is installed on the outside of the lower chute, and a material level gauge is installed on one side of the lower chute. When the bulk material pellets enter the lower chute from the upper chute, the vibrating motor and the material level gauge are turned on. Under the action of the vibrating motor, the lower chute will vibrate up and down, and the suspension spring will also swing up and down. At the same time, the suspension spring exerts a certain force on the lower chute, so that the bulk material pellets in the lower chute are shaken onto the belt conveyor, preventing the conveyor from overloaded and jammed after the bulk material hopper of the ring cooler is full, which would cause the conveyor belt of the ring cooler to burn out.

[0012] 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.

[0013] like Figure 1 , Figure 2 , Figure 3 , Figure 4 The utility model illustrates a small-angle feeding chute. Two sets of suspension springs 12 are installed below the platform support beam 17. A lower chute 9 is installed at one end of each suspension spring 12, with the springs 12 installed on both sides of the lower chute 9. A vibration motor 11 is installed on the outer side of the lower chute 9. An upper chute 8 is located at the upper end of the lower chute 9. A feed inlet 15 is located on one side of the upper chute 8. A portion of an O-ring belt roller extends into the upper chute 8 from the feed inlet 15. Bulk pellets are fed from the feed inlet 15 by the O-ring belt roller. The roller conveyor enters the upper chute 8 and then slides down to the inclined lower chute 9. The vibrating motor 11 causes the lower chute 9 to vibrate up and down. The lifting spring 12 also swings up and down under the action of the lower chute 9. At the same time, the lifting spring 12 applies a certain force to the lower chute 9, causing the bulk material pellets in the lower chute 9 to be shaken onto the belt conveyor 14. A material level gauge 16 is installed on the inner side of the lower chute 9 to observe the shaking and discharge of bulk material so that the operator can react accordingly. A frame 10 is installed on the platform support beam 17. The frame 10 is located around the upper chute 8. The upper chute 8 is provided with several brackets 1. The upper limit slot 3 is provided on the bracket 1, and the lower limit slot 5 is provided on the frame 10. A shock-absorbing device is provided between the bracket 1 and the frame 10. The upper limit slot 3 of the shock-absorbing device is provided with an upper limit pin 2, and the lower limit slot 5 is provided with a lower limit pin 6. A shock-absorbing block 4 is provided between the upper limit slot 3 and the lower limit slot 5. The shock-absorbing block 4 is installed between the upper limit slot 3 and the lower limit slot 5 through the upper limit pin 2 and the lower limit pin 6. When the vibration motor 11 drives the lower chute 9 to vibrate, the limit pin and the limit slot can be matched and inserted. The frame 10 frames the upper chute 8 inside the frame, effectively preventing the upper chute 8 from shifting as a whole. At the same time, the shock-absorbing block 4 can reduce the noise of friction during vibration. The lower end of the lower chute 9 has a belt dust collection hood 13, and a belt conveyor 14 is provided at the lower end of the belt dust collection hood 13. The belt dust collection hood 13 causes the bulk material pellets to fall onto the belt conveyor 14, preventing the bulk material from scattering.

[0014] In use, bulk pellets are transported from the feed inlet 15 to the upper chute 8 via an O-belt roller. After passing through the upper chute 8, they slide down to the lower chute 9. The dust removal hood 7 installed on the upper chute 8 can effectively remove dust from the bulk pellets during discharge, preventing operators from inhaling dust. The vibration motor 11 installed in the lower chute 9 vibrates and shakes the bulk pellets, which then slide down onto the receiving belt conveyor 14. During the process of the bulk pellets being shaken down, the operator should constantly observe the level gauge 16 and adjust the speed of the bulk pellets transported by the O-belt roller in a timely manner to avoid the accumulation of bulk material inside the ring cooler, which would cause damage to the ring cooler and require frequent maintenance.

[0015] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
