Description

Technical Field

[0001] This utility model belongs to the technical field of discharge devices, specifically relating to an anti-clogging discharge device for slag crushers. Background Technology

[0002] A slag crusher is a specialized piece of equipment used to process solid waste such as slag. It effectively processes slag by crushing it into smaller volumes. Slag crushers are widely used in industries such as metallurgy, chemicals, and building materials, and are one of the important pieces of equipment for solid waste treatment.

[0003] The slag crusher mainly consists of a feed inlet, a crushing chamber, and a discharge outlet. The feed inlet is used to feed the slag into the crushing chamber, which is equipped with crushing blades made of high-strength wear-resistant material. These blades can crush the slag into smaller volumes. The anti-clogging discharge device is an important component of the slag crusher. It can effectively prevent slag from clogging during the discharge process, thus improving the operating efficiency and safety of the equipment.

[0004] Currently, most slag crushers discharge the slag directly after crushing. The crushed slag is broken into small volumes and falls directly to the ground from the bottom of the crusher. During continuous processing, the slag falling from a height to the ground can easily cause dust. At the same time, most slag crushers have a narrow discharge port to prevent the slag from falling too scattering. Although this method can collect the crushed slag and make it easier for workers to collect, the uneven falling speed of the slag can easily cause blockage of the discharge port when falling in batches, thus affecting the normal feeding operation.

[0005] The purpose of this invention is to provide an anti-clogging discharge device for slag crushers, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: The slag crusher anti-clogging discharge device includes, The material discharge mechanism includes a housing, a discharge port, a bearing, a shaft, a spiral blade, and a motor.

The sleeve is symmetrically fixed through both sides of the frame. The movable rod is slidably sleeved inside the two sleeves. The movable rod has several anti-blocking tips distributed and fixed on the inner surface of the frame, and the anti-blocking tips are conical in shape.

[0007] As a preferred embodiment of this utility model, bearings are fixed through both sides of the frame, and shafts are inserted through and interference-fitted into the inner ring walls of two bearings distributed in the same row, and the shafts are symmetrically distributed along both ends of the frame.

[0008] As a preferred embodiment of this utility model, a crushing roller for crushing slag is fixedly sleeved on the surface of the second shaft. The surface of the crushing roller has a number of teeth, and the teeth on the crushing roller distributed along both sides are arranged in an alternating manner.

[0009] As a preferred embodiment of this utility model, the upper end of the frame is fixedly covered with a cover plate, the middle of the cover plate is provided with a feed inlet, and a funnel is fixedly installed on the upper end of the cover plate, with the lower end of the funnel fitting into the position of the feed inlet.

[0010] As a preferred embodiment of this utility model, guide blocks are symmetrically distributed and fixed on both sides of the upper end of the inner wall of the frame, and the gap between the two guide blocks corresponds to the position of the feed inlet.

[0011] As a preferred embodiment of this utility model, guide blocks two are symmetrically distributed and fixed on both sides at the middle position of the inner wall of the frame, and the gap between the two guide blocks two corresponds to the position of the U-shaped channel of the outer shell.

The motor-driven shaft rotates the spiral blades, achieving a continuous and stable spiral discharge method. 2. This solution effectively prevents material blockage by using a reciprocating anti-blocking tip. The motor drives the eccentric wheel to rotate, which in turn drives the moving rod to reciprocate, causing the conical anti-blocking tip to continuously disturb the accumulated slag. The spring ensures the stable reset of the anti-blocking tip during reciprocating motion. Attached Figure Description

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Example 1 Reference Figures 1-5 This is the first embodiment of the present invention, which provides an anti-clogging discharge device for a slag crusher, including: The discharge mechanism 1 includes a housing 10, a discharge port 11, a bearing 12, a shaft 13, a spiral blade 14, and a motor 15. A U-shaped channel for transitional discharge is provided in the middle of the housing 10. The bearing 12 is fixedly installed through the housing 10 on the side away from the discharge port 11. The shaft 13 is inserted through and interference-fitted into the inner wall of the bearing 12. The spiral blade 14 is wound and fixedly fixed to the surface of the shaft 13. The motor 15 is fixedly mounted on the outer end of the housing 10 via a bracket. A drive shaft is provided inside the motor 15, and the end of the drive shaft is engaged with the shaft 13. The connection is fixed by a coupling. When the small volume of pulverized slag needs to be discharged, the slag will fall into the U-shaped channel of the outer shell 10 and be discharged only through the discharge port 11. Compared with a large-scale outlet, this can reduce dust. When continuous discharge is required, the power supply of motor 15 is turned on, so that motor 15 rotates the shaft, which can realize the linkage of shaft 13. Shaft 13 rotates stably based on bearing 12. Shaft 13 can drive the spiral blade 14 to realize spiral discharge. The outer spiral surface of the spiral blade 14 is slidably attached to the inner wall of the U-shaped channel. The crushing mechanism 2 includes a frame 20. The bottom of the frame 20 is fixed to the upper end of the outer shell 10. The frame 20 can form a crushing chamber, and the crushing components can be placed inside the frame 20. The anti-blocking mechanism 3 includes a sleeve 30, a movable rod 31, and anti-blocking tips 32. The sleeves 30 are symmetrically fixed through both sides of the frame 20. The movable rods 31 are slidably connected inside the two sleeves 30. Several anti-blocking tips 32 are distributed and fixed on the inner surface of the movable rods 31, and the anti-blocking tips 32 are conical structures. The movable rods 31 can slide based on the sleeves 30 and drive the anti-blocking tips 32 to move. Thus, when the slag is collected during feeding, the accumulated slag can be moved, thereby avoiding blockage.

[0021] Among them, bearings 21 are fixed through both sides of the frame 20. Shafts 22 are inserted through and interference-fitted on the inner ring walls of the two bearings 21 distributed in the same row. Shafts 22 are symmetrically distributed along both ends of the frame 20. Shafts 22 can rotate stably based on bearings 21 and drive the crushing roller 23 to rotate.

[0022] Among them, the surface of the shaft 22 is fixedly sleeved with a crushing roller 23 for crushing slag. The surface of the crushing roller 23 has a number of teeth. The teeth on the crushing roller 23 distributed along both sides are staggered. Both crushing rollers 23 rotate inward. The staggered teeth can be used to crush large slag when it enters.

[0023] The upper end of the frame 20 is fixedly covered by a cover plate 201. A feed inlet 205 is provided in the middle of the cover plate 201. A funnel 202 is also fixedly installed on the upper end of the cover plate 201. The lower end of the funnel 202 is fitted with the position of the feed inlet 205. The cover plate 201 can close the upper end of the frame 20. Material can be fed through the feed inlet 205. With the help of the funnel 202, the slag material to be crushed can be prevented from spilling out during feeding.

[0024] Among them, guide blocks 203 are symmetrically distributed and fixed on the upper end of the inner wall of the frame 20. The gap between the two guide blocks 203 corresponds to the position of the feed inlet 205. The two guide blocks 203 enable the material to be crushed to gather between the two crushing rollers 23 when it enters the feed inlet 205, thus ensuring the stability of the crushing process.

[0025] Among them, guide blocks 204 are symmetrically distributed and fixed on both sides of the inner wall of the frame 20. The gap between the two guide blocks 204 corresponds to the position of the U-shaped channel of the outer shell 10. The two guide blocks 204 can appropriately gather the material after crushing, so that it can fall stably into the U-shaped channel of the outer shell 10.

[0026] Among them, a second motor 24 is fixedly installed on the outer end of the frame 20. The second motor 24 has a rotating shaft 2 inside for driving. The end of the rotating shaft 2 is fixedly connected to the shaft 22 through a coupling. The two second motors 24 have the same model and speed. The rotating shafts of the two second motors 24 rotate in opposite directions, so that the two crushing rollers 23 can be linked synchronously to achieve accurate rotational coordination for crushing materials.

[0027] Among them, the outer end of the frame 20 is also fixed with a motor 301 via a bracket. The motor 301 has a rotating shaft 3 for driving inside, and an eccentric wheel 302 is fixedly installed at the end of the rotating shaft 3. Both ends of the moving rod 31 are fixedly installed with extrusion plates 33. The proximal and distal ends of the eccentric wheel 302 are always in close contact with the surface of the extrusion plate 33. The surface of the moving rod 31 is wrapped with a spring 34. The two ends of the spring 34 are fixedly installed with the surface of the extrusion plate 33 and the outer wall of the frame 20, respectively. When it is necessary for the anti-blocking tip 32 to reciprocate and converge at both ends... When the material between the guide blocks 204 is being cleared, the power supply to the motor 301 is turned on, enabling the rotating shaft 3 to drive and the eccentric wheel 302 to rotate. The eccentric wheel 302 can continuously contact the extrusion plate 33 on one side through its near and far ends, achieving the operation of extrusion and release. At this time, the moving rod 31 can slide inside the rod sleeve 30 and drive the anti-blocking tip 32 to move back and forth. The springs 34 on both sides have compression, stretching and reset changes respectively, which can ensure the stability of the anti-blocking tip 32 during the reciprocating movement.

[0028] In practice The discharge mechanism 1 of this scheme achieves dust suppression and discharge by cooperating with the screw conveyor and the U-shaped channel. The motor 15 drives the rotating shaft 1 to rotate the shaft 13. The shaft 13 is supported on the side wall of the outer shell 10 by the bearing 12. The spiral blades 14 on its surface are tightly attached to the inner wall of the U-shaped channel to form a sealed spiral propulsion space. When the crushed slag falls into the U-shaped channel, the rotation of the spiral blades 14 pushes the material along the channel to the discharge port 11. The narrow discharge port 11 restricts the spread of dust. The structural design of the U-shaped channel extends the material residence time and ensures the uniformity of conveying. Shaft 22 is supported on both sides of frame 20 by bearing 21. Motor 24 drives shaft 2 to rotate shaft 22, causing the two crushing rollers 23 to rotate synchronously in opposite directions. The teeth on the surface of crushing rollers 23 are staggered and generate shear force when they rotate inward. When large pieces of slag fall from hopper 202 through feed port 205 into guide block 203, the material is forced to be guided into the meshing gap of the two crushing rollers 23. The material is crushed by the interlocking and tearing of the teeth. Guide block 204 further gathers the crushed material into the U-shaped channel of outer shell 10 to ensure the concentration of material feeding. Motor 301 drives eccentric wheel 302 to rotate, and its near and far ends periodically squeeze the two squeeze plates 33, pushing the moving rod 31 to slide back and forth in the rod sleeve 30. This causes the anti-blocking tip 32 to penetrate the material gathered in guide block 204. The conical anti-blocking tip 32 breaks up the material agglomerates through reciprocating motion and destroys the slag that is blocking the accumulation. Spring 34 connects the squeeze plate 33 to the outer wall of frame 20 and provides a restoring force when the eccentric wheel 302 disengages from the squeeze, ensuring that the moving rod 31 returns to its initial position.
