Description

Technical Field

[0001] This utility model relates to the field of feeding mechanism technology, specifically a feeding mechanism for a Raymond mill. Background Technology

[0002] Raymond mill, also known as a suspended roller disc mill or pendulum mill, is a crushing equipment widely used in mineral processing, building materials, chemical and other industries. Corrosion-resistant carbon bricks, due to their special corrosion resistance and high temperature resistance, have strict requirements on the fineness and uniformity of raw materials. Raymond mill and its feeding mechanism play a crucial role in the production of corrosion-resistant carbon bricks, ensuring that the processing accuracy of raw materials meets production requirements.

[0003] Although Raymond mills offer many benefits, they still have the following problems: relying on manual adjustment or simple mechanical gates makes it difficult to respond to changes in mill load in real time, leading to inaccurate adjustment of feed and fluctuations in ink flow efficiency. Secondly, the hygroscopic and pressure-sensitive nature of petroleum calcined coke powder causes bridging and slab formation in the silo, as well as interruptions in feeding or sudden changes in flow rate.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a feeding mechanism for a Raymond mill, including:

[0035] Please see Figures 1-5The feeding mechanism of a Raymond mill according to this embodiment includes an arch-breaking component 2. The inner side wall of the arch-breaking component 2 is provided with a drive shaft 230. The outer circumferential wall of the drive shaft 230 is provided with a guide groove 240. Multiple arch-breaking frames 250 are fixedly connected to the outer circumferential wall of the drive shaft 230 by bolts. An arch-breaking rack 270 is integrally formed and connected to the side wall of the arch-breaking frame 250. A scraper 260 is integrally formed and connected to the side wall of the arch-breaking frame 250. A bracket 280 is rotatably connected to the bottom of the drive shaft 230. A second chamber 220 is fixedly connected to the bottom of the bracket 280. A discharge component 3 is provided at the bottom of the second chamber 220.

[0036] The discharge assembly 3 includes a float 330, a connecting rod 340 fixedly connected to the side wall of the float 330, a hopper 310 hinged to the side wall of the connecting rod 340, a connecting rod 350 hinged to the other end of the connecting rod 340, a connecting rod 360 hinged to the other end of the connecting rod 350, a gate 320 hinged to the other end of the connecting rod 360, and an adjusting member 370 slidably connected to the outer side wall of the connecting rod 360.

[0037] It is worth noting that, in order to provide active driving force, specifically, the top of the second chamber 220 is fixedly connected to the first chamber 210, the top of the first chamber 210 is fixedly connected to the top cover 1 via a flange, the top of the top cover 1 is integrally connected to the feed pipe 110, the top of the top cover 1 is fixedly connected to the motor 130, the top of the top cover 1 is provided with a button 120, the button 120 is electrically connected to the motor 130, and the output end of the motor 130 is connected to the drive shaft 230 via a transmission shaft.

[0038] Next, in order to improve the discharge efficiency, specifically, the second compartment 220 is a conical structure with an inclination angle of 60 degrees to increase the material flow rate. The support 280 is located at one-third of the inner side wall of the second compartment 220, so that the arch-breaking frame 250 is located in the easy-to-clog bridge area at the connection between the first compartment 210 and the second compartment 220, thereby improving the arch-breaking efficiency.

[0039] Meanwhile, in order to improve the arch breaking efficiency, specifically, the guide channel 240 has a spiral structure to drive the material to flow downwards, the scraper 260 has a square structure to scrape off the adhering layer on the inner wall of the chamber 210, the arch breaking frame 250 has an arc-shaped structure to improve its own structural strength, and the arch breaking rack 270 has a serrated structure to improve the arch breaking efficiency.

[0040] Furthermore, in order to improve the sealing performance of the hopper 310, specifically, the side wall of the hopper 310 is provided with a connecting groove, and multiple sealing gaskets 311 are bonded to the inner side wall of the connecting groove for sealing and protection to prevent material leakage. The sealing gaskets 311 have a hemispherical structure to reduce the contact area and facilitate the movement of the connecting rod 340. The side wall of the sealing gasket 311 is in contact with the connecting rod 340.

[0041] It is worth noting that, in order to facilitate material discharge, the hopper 310 has a square structure. The outer wall of the hopper 310 is integrally formed and connected with multiple rotating shafts. The circumferential outer wall of the rotating shaft is fitted with the gate 320 to facilitate the rotation and opening of the gate 320. The gate 320 has a fan-shaped structure.

[0042] Finally, to facilitate the opening and adjustment of the gate 320, the adjusting component 370 includes a sleeve 371. A friction pad 372 is bonded to the inner wall of the sleeve 371 to increase the friction of the contact surface. A connecting rod 360 is slidably connected to the inner wall of the friction pad 372. A counterweight 373 is fixedly connected to the bottom of the sleeve 371. By adjusting the center of gravity of the connecting rod 360 through the sliding adjusting component 370, the weight requirement of the material on the top of the float 310 for the opening of the gate 320 is changed.

[0043] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0044] Combination Figures 1-5 The feeding mechanism of a Raymond mill according to this embodiment is used in the following specific process:

[0045] 1: Material is fed into the feed pipe 110, and then the motor 130 is started by controlling the button 120. The motor 130 drives the drive shaft 230 to rotate and start the arch breaking operation of the material.

[0046] 2: When the material is inside the first compartment 210, it flows downward through the guide channel 240. When the material flows to the connection between the first compartment 210 and the second compartment 220, it is easy for bridging to occur, which leads to material accumulation and blockage. At this time, the material is broken by the anti-bridging frame 250 and the anti-bridging rack 270, while the scraper 260 scrapes off the attached layer on the inner circumference of the first compartment 210. Then the material is discharged into the silo 310 through the second compartment 220.

[0047] 3: When the material moves to the hopper 310, the material presses down on the float plate 330. The float plate 330 is rotated through the first connecting rod 330, which, in conjunction with the second connecting rod 340 and the third connecting rod 360, pulls the gate 320 to open. The center of gravity of the third connecting rod 360 can also be changed through the sliding adjustment component 370, thereby changing the weight requirement of the material piled on top of the float plate 330 for the gate 320 to open.

[0048] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
