Description

Technical Field

[0001] This utility model relates to the field of coal gangue processing technology, and in particular to a device for producing and preparing ceramsite for the comprehensive utilization of coal gangue. Background Technology

[0002] Coal gangue is a solid waste generated during coal mining and coal processing. It is characterized by its large volume and high difficulty in treatment. Therefore, developing effective utilization technologies to transform it into valuable building materials is of great economic and environmental significance. The production of expanded clay can effectively reduce the environmental impact of coal gangue and realize the recycling of resources.

[0003] The production of ceramsite for the comprehensive utilization of coal gangue typically includes steps such as raw material preparation, mixing, molding, sintering, cooling, screening, and packaging. The molding step is carried out by granulation using a screw extruder. The screw extruder consists of a screw extrusion sleeve, a drive mechanism, an extrusion module, and a cutting mechanism. The extrusion module is usually installed by a fixing cap, which is threaded onto the end of the outer wall of the extrusion sleeve to install and fix the extrusion module.

[0004] However, when the screw extruder is working, it will vibrate due to mechanical movement. Since the fixing cap is installed by thread, it may loosen due to mechanical vibration during the operation of the screw extruder. This will cause material to flow out from the gap between the extrusion sleeve, the extrusion module and the fixing cap. This not only leads to material waste, but the material entering the gap will also affect the disassembly and maintenance of the extrusion module and the fixing cap, thus creating certain defects.

[0039] 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.

[0040] This utility model provides, for example Figure 1-4 The device shown is a production and preparation device for the comprehensive utilization of coal gangue in the production of ceramsite.

[0041] Example 1

[0042] The device includes a screw extrusion sleeve 1, an extrusion module 2, a fixing cap 3, a cutting assembly 4, and a locking assembly 5. The extrusion module 2 is slidably engaged with one end of the inner cavity of the screw extrusion sleeve 1. The fixing cap 3 is threaded onto one end of the outer wall of the screw extrusion sleeve 1. The fixing cap 3 is used to fix and bind the extrusion module 2, thereby ensuring the stability of the extrusion module 2 installed at one end of the screw extrusion sleeve 1. The cutting assembly 4 is located on one side of the fixing cap 3. The cutting assembly 4 is used to cut the material discharged from the extrusion module 2. Under the action of an external drive source, the screw extrusion sleeve 1 causes the extrusion module 2 to discharge material. The cutting assembly 4 cuts the extruded material, thereby achieving granulation. The locking assembly 5 is located on the outside of the screw extrusion sleeve 1. The locking assembly 5 is used to engage and bind the fixing cap 3, thereby preventing the fixing cap 3 from loosening due to mechanical vibration.

[0043] Furthermore, the cutting assembly 4 includes a fixed bracket 41, a servo motor 42, and a cutting blade 43. The fixed bracket 41 is fixedly connected to one side of the fixed cap 3, the servo motor 42 is installed on one side of the fixed bracket 41, and the cutting blade 43 is driven and installed at the output end of the servo motor 42. The cutting blade 43 works in conjunction with the extrusion module 2, so that the servo motor 42 can drive the cutting blade 43 to rotate, thereby cutting the material.

[0044] In particular, the locking assembly 5 includes a fixing collar 51, a braking block 52, a first locking tooth 54, a second locking tooth 55, and a limiting assembly 53. The fixing collar 51 is fixedly sleeved on the outside of the screw extrusion sleeve 1. The outer wall of the braking block 52 is slidably sleeved with the fixing collar 51, and one end of the braking block 52 is slidably engaged with the fixing cap 3. The limiting assembly 53 is disposed on the side of the fixing collar 51 away from the fixing cap 3, and the limiting assembly 53 is used to limit the braking block 52. An annular groove is provided on one side of the fixing cap 3, and the first locking tooth 54 is arranged in an annular array. The first tooth 55 is fixedly connected to the inside of the annular groove and is fixedly connected to one end of the brake block 52. The second tooth 55 is slidably engaged with the first tooth 54, and the first tooth 54 and the second tooth 55 have an inclined slope on the opposite side. So when the fixing cap 3 is tightened, the first tooth 54 can squeeze the inclined surface of the second tooth 55, causing the brake block 52 to slide away from the fixing cap 3, so that the fixing cap 3 can be rotated and tightened. When the first tooth 54 and the second tooth 55 are engaged on the relatively parallel sides, the fixing cap 3 can be locked and bound.

[0045] Furthermore, the limiting component 53 includes a connecting plate 531, a connecting rod 532, a limiting block 533, and a limiting spring 534. The connecting plate 531 is fixedly connected to the other end of the brake block 52. One end of the connecting rod 532 is fixedly connected to the fixing collar 51. The outer wall of the connecting rod 532 is slidably inserted into the connecting plate 531. The limiting block 533 is fixedly connected to the end of the connecting rod 532. The limiting spring 534 is slidably sleeved on the outside of the connecting rod 532. The limiting spring 534 is located between the connecting plate 531 and the limiting block 533. Under the action of the limiting spring 534, the connecting plate 531 can give the brake block 52 an elastic force toward the fixing cap 3, thereby ensuring the stability of the engagement between the first locking tooth 54 and the second locking tooth 55.

[0046] Example 2

[0047] Based on Embodiment 1, the limiting assembly 53 further includes a limiting sleeve 535, a mounting sleeve 539, a slider 536, and an annular groove 538. The limiting sleeve 535 is rotatably mounted on one side of the connecting plate 531 via the mounting sleeve 539, that is, the mounting sleeve 539 is fixedly connected to one side of the connecting plate 531. One end of the outer wall of the limiting sleeve 535 is rotatably sleeved with the mounting sleeve 539. The slider 536 is fixedly connected to the side of the limiting block 533. The interior of the limiting sleeve 535 has a groove 537 that matches the slider 536. An annular groove 538 is formed inside the limiting sleeve 535. The inner cavity of the annular groove 538 is connected to the inner cavity of the slide groove 537. The width of the annular groove 538 is greater than the width of the slider 536. Thus, the limiting sleeve 535 drives the connecting plate 531 and the brake block 52 to move away from the fixed cap 3. By rotating the limiting sleeve 535, the slider 536 is locked inside the annular groove 538. This allows the brake block 52 to drive the second locking tooth 55 to be in a stable state and separate from the first locking tooth 54, thereby allowing the fixed cap 3 to be disassembled.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
