Abstract
Description
Technical Field
[0001] This utility model relates to the field of cement processing technology, specifically to a cement processing screening machine. Background Technology
[0002] The main raw material of cement is lime or calcium silicate. After hardening, it can resist the erosion of fresh water or salt water. As an important cementing material, it is widely used in civil engineering, water conservancy and road construction projects. However, existing cement needs to be screened during processing.
[0003] Vibrating screens are one of the most commonly used screening equipment in cement processing. They use a high-frequency vibrating motor to generate excitation force, causing the screen surface to vibrate, thereby achieving material screening. Vibrating screens have advantages such as high screening efficiency, large processing capacity, and simple structure, and are suitable for screening cement raw materials and finished products of various particle sizes. However, if the screen mesh is installed inside the screening machine, it becomes difficult to repair if the screen mesh is damaged or blocked. Therefore, a cement processing screening machine is proposed. Utility Model Content

[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] Please see Figure 1-4 A cement processing screening machine includes a frame 1, an elastic element 2 fixedly installed on the top of the frame 1, the elastic element 2 including two end plates, a spring fixedly installed between the two end plates, the lower end plate fixedly installed on the frame 1, and the top end plate fixedly installed on the support 3. The support 3 is fixedly installed on the top of the elastic element 2, and a screening shell 4 is detachably installed on the top of the support 3. By setting the height of the left end elastic element 2 higher than the height of the right end elastic element 2, the screening shell 4 can be tilted to facilitate the rapid rolling of cement raw materials.
[0014] Please see Figure 1-4 The top of the screening shell 4 is hinged to a screening top cover 5, and a screening hopper 6 is fixedly installed on the top of the screening top cover 5. At the same time, a filter screen is embedded in the screening hopper 6 to achieve preliminary treatment of cement raw materials. Hydraulic pneumatic rods 7 are movably hinged between both ends of the screening shell 4 and the screening top cover 5. After the screening top cover 5 is rotated open, the hydraulic pneumatic rods 7 can be used to support the screening top cover 5.
[0015] Please see Figure 1-4 The flange plate of the screening shell 4 and the screening top cover 5 are detachably connected by a locking component 8. The locking component 8 can be the existing product Bogong GH-431 self-locking plate buckle. The locking component 8 in the attached figure is a schematic diagram and is not the same as the Bogong plate buckle. The locking component 8 can be used to directly fix the screening shell 4 and the screening top cover 5, and can also facilitate the opening of both.
[0016] Please see Figure 5-6 Inside the screening shell 4, a first mounting frame 9, a second mounting frame 11, and a third mounting frame 13 are fixedly installed from top to bottom. The first mounting frame 9, the second mounting frame 11, and the third mounting frame 13 are L-shaped, and screen mesh pre-reserved holes are opened on their surfaces. The first layer of screen mesh 10, the second layer of screen mesh 12, and the third layer of screen mesh 14 are movably embedded inside the first mounting frame 9, the second mounting frame 11, and the third mounting frame 13, respectively. The mesh diameter of the first layer of screen mesh 10, the second layer of screen mesh 12, and the third layer of screen mesh 14 gradually decreases from top to bottom, so as to realize the step-by-step screening of cement raw materials and ensure that the particles of cement raw materials meet national standards.
[0017] Please see Figure 5-6A limiting protrusion 15 is fixedly installed on the inner wall of the first mounting frame 9, the second mounting frame 11, and the third mounting frame 13, and below the screen. A strip groove 16 is formed on the surface of the first mounting frame 9, the second mounting frame 11, and the third mounting frame 13, as well as on the surface of the first layer screen 10, the second layer screen 12, and the third layer screen 14. A limiting pressure plate 17 is detachably installed inside the strip groove 16 via bolts 18. Each screen is embedded in a pre-drilled hole in the screen, and then the limiting pressure plate is placed in the strip groove 16. Finally, the bolts 18 are threaded onto the mounting frame.
[0018] Please see Figure 1-4 The bottom of the screening shell 4 is fixedly mounted with a vibration motor 21 via a mounting base. The vibration motor 21 is controlled by a corresponding controller. Each of the four discharge ports at the bottom of the screening shell 4 is fixedly mounted with a discharge hopper 19. An extension pipe 20 is fixedly mounted at the bottom of the discharge hopper 19. The extension pipe 20 can be a semi-flexible pipe for easy bending. The four extension pipes 20 are arranged in a staggered and equally spaced manner to ensure that cement raw materials of different particles are discharged separately without interfering with each other.
[0019] Working principle: During use, the vibration motor 21 is controlled to operate, and its vibration force is transmitted to the screening shell 4. The screening shell 4 will shake the three layers of screens inside it. Then, the cement raw materials are poured into the machine through the screening hopper 6. The shaking three screens can realize the four-layer screening of cement raw materials. Finally, the cement raw materials of four different particle sizes enter the discharge hopper 19 and are discharged to different processing steps through the extension pipe 20, thereby realizing the screening of cement raw materials of different particle sizes.
[0020] If the screen is damaged or clogged, first open the locking device 8, then lift the top cover 5 upwards and use the hydraulic pneumatic rod 7 to support the top cover 5. Then the first mounting bracket 9 and the first layer of screen 10 will be exposed. Then, use tools to remove the bolts 18 to remove the limiting pressure plate 17, and then remove the first layer of screen 10. Repeat this operation to remove the second layer of screen 12 and the third layer of screen 14, thereby achieving the purpose of repairing the screen inside the installed screening machine.
[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
