Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a crusher for gypsum calcination with a screening mechanism. Background Technique

[0002] Gypsum calcination is a key link in the gypsum processing process. By controlling the temperature and time, different physical and chemical properties are imparted to the gypsum to meet the requirements in fields such as construction and chemical engineering. Before gypsum calcination, it is usually necessary to carry out crushing treatment to increase the specific surface area of gypsum particles, promote their contact with the heat source or reaction medium, thereby improving the dehydration efficiency, reaction activity and subsequent processing performance.

[0003] Traditional gypsum crushers can only achieve a single crushing operation. The crushed gypsum materials contain fragments of different sizes, and these fragments still need to be screened subsequently. The crushing and screening processes cannot be carried out synchronously, resulting in low processing efficiency. Content of the Utility Model

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-7 A gypsum calcination pulverizer with a screening mechanism includes a pulverizer body 1, a pair of pulverizing rollers 31 installed in the middle of the pulverizer body 1, and a material discharge port 8 provided below the pulverizing rollers 31, through which the pulverized material falls.

[0027] Multiple screens 5 are installed below the discharge port 8 via the mounting groove 10. A tray 6 is installed below the screens 5, and a discharge port 4 is provided on the side away from the screens 5.

[0028] Each screen 5 has a different aperture, which gradually decreases from top to bottom. The specific screening specifications are configured by those skilled in the art based on actual production conditions and will not be explained further.

[0029] A ring of insertion blocks 7 is installed on the outer side of both the screen 5 and the tray 6. The insertion blocks 7 and the mounting groove 10 opened at the bottom of the crusher body 1 are docking mechanisms. By inserting the insertion blocks 7 on the outer side of the screen 5 and the tray 6 into the mounting groove 10, the snap-fit ​​assembly operation of the screen 5 and the tray 6 is completed.

[0030] The top and bottom walls of the mounting groove 10 are both fitted with extrusion plates 12 via springs 3 15. When the screen 5 and tray 6 are installed into the mounting groove 10, the plug-in block 7 is pressed and connected to the extrusion plate 12, and the springs 3 15 deform.

[0031] The vibration effect is achieved by setting up spring 3 15 and compression plate 12.

[0032] A plug-in post 9 is installed on one side of the discharge port 4 via a spring 11. One end of the plug-in post 9 passes through the discharge port 4 and the mounting groove 10 in sequence and extends into the through groove 51 opened on one side of the screen 5. A connecting groove 13 is opened at the upper and lower parts of one end of the plug-in post 9, and a movable block 91 is installed in the groove. The movable block 91 is connected to the connecting groove 13 via a spring 2 14.

[0033] A feed inlet 2 is installed on the upper side of the crusher body 1, and the feed inlet 2 is connected to the inside of the crusher body 1.

[0034] The crusher body 1 has an “U”-shaped mounting groove 10 on the bottom side inside, which is used to connect the plug-in block 7.

[0035] The mounting slot 10 is inclined so that materials can be dropped at an angle.

[0036] One end of the plug block 7 has a horizontal through groove 51, which is used to connect to the plug post 9.

[0037] A slot is provided on one side of the discharge port 4, and a plug-in post 9 is slidably installed at the slot. The plug-in post 9 is connected to the outer wall of the discharge port 4 through a spring 11. When the plug-in post 9 moves, the spring 11 deforms.

[0038] Vibration motors 16 are installed on the middle of one side of both the screen 5 and the tray 6. The vibration motors 16 are connected to an external power source via wires to make the screen 5 and the tray 6 vibrate.

[0039] In this embodiment, gypsum material is introduced through the feed inlet 2, and the gypsum material is crushed by the pulverizing roller 31 driven by the motor 3 through the pulverizing roller. The crushed gypsum material is in the form of fragments of different sizes, which fall onto the screen 5 through the discharge port 8. At the same time, the vibration motor 16 on one side of the screen 5 runs and drives the screen 5 to vibrate irregularly in the mounting groove 10 so as to vibrate and screen the material. The material after multiple screenings falls into the bottom tray 6 for collection.

[0040] By pulling out the plug 9, the plug 9 is disengaged from the plug block 7 on one side of the screen 5 and tray 6. At this time, the screen 5 and tray 6 are in a detachable state, and can be pulled out by pulling out the screen 5 and tray 6.

[0041] During the installation of screen 5 and tray 6, the plug-in block 7 is inserted into the mounting groove 10. The pressing plate 12 in the mounting groove 10 is displaced by the insertion and pressing of the plug-in block 7, which causes the spring 3 15 to deform. The pressing plate 12 is stably pressed on the screen 5 and tray 6. In the subsequent vibration process, the pressing plate 12 works with the spring 3 15 to ensure the vibration effect.

[0042] During the installation of the screen 5 and tray 6, the plug-in post 9 and the outer wall of the plug-in block 7 are pressed together. When the plug-in block 7 is fully inserted into the installation groove 10, the position of the through groove 51 on one side of the plug-in block 7 corresponds to that of the plug-in post 9. Under the action of the spring 14, the plug-in post 9 is inserted into the through groove 51 and the snap-fit ​​is completed.

[0043] During the subsequent vibration process, a set of movable blocks 91 set on the plug post 9 ensures the vibration effect.

[0044] Because of the snap-fit ​​assembly between the plug block 7 and the mounting groove 10, the screen 5 will not come out of the mounting groove 10 no matter how irregularly it moves.

[0045] The crushing roller 31 achieves the rotary crushing function through the crushing roller motor 3 and gear transmission mechanism. The more detailed transmission structure and principle are not explained here, as they are common knowledge to those skilled in the art.

[0046] The tray 6 is located at the bottom of the crusher body 1, below the screen 5, so as to collect the material after it has been screened by the screen 5.

[0047] The installation groove enables quick assembly and disassembly of the screen 5 and tray 6 to remove materials. Both the screen 5 and tray 6 are equipped with a vibration motor 16 to achieve vibratory screening. Spring assemblies are also provided on the installation groove and the plug-in column 9 to assist vibration and effectively ensure screening effect.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
