Description

Technical Field

[0001] This utility model belongs to the field of calcium carbonate production technology, and specifically relates to a raw material processing device for calcium carbonate production. Background Technology

[0002] Calcium carbonate is a common inorganic compound with the chemical formula CaCO3, composed of calcium, carbon, and oxygen. It is widely found in nature, being a major component of minerals such as limestone, marble, and calcite, and also an important part of seashells and eggshells. Industrially, calcium carbonate has a wide range of uses, serving as a filler in building materials (such as cement production), plastics, and rubber to enhance hardness, and is also used in papermaking, coatings, toothpaste, and other products. In the food industry, it is often used as a calcium supplement or food additive. Furthermore, calcium carbonate is insoluble in water but reacts with acids to produce carbon dioxide, a property that gives it special value in both laboratory and practical applications. In the calcium carbonate production process, screening devices are used to classify the crushed ore raw materials to facilitate subsequent processing. In the existing screening devices, the screen is fixed to the screening machine body with multiple sets of bolts. However, when screening ore, the sharp edges of the surface will cause wear to the screen, requiring frequent disassembly and replacement of the worn screen. Moreover, the screen fixed with multiple sets of bolts needs to be disassembled one by one when disassembling, resulting in low maintenance efficiency. Utility Model Content

[0013] 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.

[0014] Please see Figures 1-6This utility model provides the following technical solution: A raw material processing device for calcium carbonate production, comprising a screening machine body 1, a slot 2 formed on the top surface of the screening machine body 1, a plug 3 inserted into the surface of the slot 2, a locking block 4 adhered to the surface of the plug 3, the surface of the locking block 4 engaging with the surface of the slot 2, the top surface of the plug 3 connected to the bottom of the horizontal end of a side plate 5, a screen 6 connected to the bottom surface of the horizontal end of the side plate 5, the screen 6 fitting snugly against the inner wall of the screening machine body 1, a fixing block 7 connected to one side surface of the screening machine body 1, the surface of the fixing block 7 being rotatably connected to a connecting ear 9 via a rotating shaft 8, the top surface of the connecting ear 9 being connected to the bottom of a baffle 10. The top surface of the baffle 10 is connected to the feed hopper 11, and the bottom surface of the baffle 10 abuts against the top opening of the screen 6. The side surface of the baffle 10 away from the fixed block 7 is connected to the limiting rod 12. The inner wall surface of the limiting rod 12 is sleeved with the first insert rod 13. The surface of the first insert rod 13 is inserted into the surface of the side block 14. The surface of the side block 14 is connected to the surface of the screening machine body 1. In this design, the screening machine body 1 forms the main body of the linear vibrating screen, and a large number of related components are set in the main body of the linear vibrating screen. Since they are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution. The main model of the linear vibrating screen in this solution is: Zhongzhi 520.

[0015] In operation: The linear vibrating screen is driven by two vibrating motors. When the two motors rotate synchronously in opposite directions, the excitation forces generated by the eccentric blocks cancel each other out in the direction parallel to the motor axis, and are superimposed into a resultant force in the direction perpendicular to the motor axis, causing the screen to move in a linear trajectory. The two motor shafts are at an angle relative to the screen surface. Under the combined action of the excitation force and the gravity of the calcium carbonate raw material ore, the ore is thrown up on the screen surface of screen 6 and moves forward in a straight line in a jumping manner. During this process, ores of different particle sizes are screened through screen 6 and discharged from their respective outlets, achieving screening and grading.

[0016] Preferably, two sets of slots 2 are symmetrically opened on the top of the screening machine body 1. The slots 2 are trapezoidal grooves, and their shape and size are adapted to the insert block 3.

[0017] In practical use, the insert 3 connected to the bottom of the side plate 5 is inserted into the slot 2 until the card block 4 attached to the surface of the insert 3 engages and is fixed in the circular groove on the surface of the slot 2, thereby fixing the screen 6 at the top of the screening machine body 1.

[0018] Preferably, a set of clips 4 are symmetrically bonded to the surface of the insert 3. The clips 4 are made of spherical rubber material and their shape and size are adapted to the circular groove at the upper end of the slot 2.

[0019] In actual use, the clip 4, which is attached to the surface of the insert 3, is engaged and fixed in the slot 2, thereby fixing the screen 6 at the top of the screening machine body 1.

[0020] Preferably, the side plate 5 is an L-shaped integrated structure, with a set of insert blocks 3 and locking blocks 4 symmetrically distributed on its transverse end surface.

[0021] In actual use, the insert block 3 and the locking block 4 at the bottom of the side plate 5 are respectively inserted into the slots 2 symmetrically opened at the top of the screening machine body 1, thereby fixing the screen 6 at the top of the screening machine body 1.

[0022] Preferably, the surface of the first insert rod 13 is connected to the threaded head 15, the surface of the threaded head 15 is threadedly connected to the second insert rod 16, the surface of the side block 14 is inserted into the second insert rod 16, and the surface of the second insert rod 16 is sleeved on the inner wall of the limiting rod 12.

[0023] In practical use, the side blocks 14 symmetrically distributed on both sides of the screening machine body 1 allow the first insertion rod 13 and the second insertion rod 16 to be inserted into the side blocks 14 from both sides respectively, and finally threaded into the limiting rod 12, thereby facilitating the connection of the first insertion rod 13 and the second insertion rod 16 to stably fix the baffle 10 at the top of the screening machine body 1.

[0024] Preferably, the first insert rod 13, the threaded head 15, and the second insert rod 16 form a threaded connection structure, and a set of side blocks 14 are symmetrically distributed on the surface of the screening machine body 1, and the surface of the side blocks 14 is provided with circular through grooves, the shape and size of which are adapted to the first insert rod 13 and the second insert rod 16.

[0025] In practical use, the circular through grooves opened on the surface of the side blocks 14 are inserted into the circular through grooves opened on the surface of the limiting rod 12 until the threaded head 15 on the surface of the first insert rod 13 abuts against the threaded groove opened on the surface of the second insert rod 16, thereby connecting the two and rotating the first insert rod 13 so that the threaded head 15 at its front end is threadedly connected to the second insert rod 16, thereby fixing the baffle 10 at the top of the screening machine body 1.

[0026] Working principle: In the calcium carbonate production process, the crushed ore raw material is screened and graded using the screening machine body 1 for subsequent use and processing. A screen 6 with a suitable mesh size is selected according to production needs. Then, the side plates 5 connected to the top two sides of the screen 6 are held, and the screen 6 is pressed against the top of the screening machine body 1. The insert block 3 connected to the bottom of the side plate 5 is then inserted into the slot 2 until the locking block 4 adhered to the surface of the insert block 3 engages and is fixed in the circular groove on the surface of the slot 2, thus fixing the screen 6 in the position at the top of the screening machine body 1. At this point, the handle at the front end of the baffle 10 can be held, and the rotating shaft 8 connected to its other side can be rotated to... The baffle 10 can be rotated and raised until the bottom of the baffle 10 abuts against the top of the screen 6. At this time, the limiting rod 12 connected to the other side of the baffle 10 can abut against the front surface of the screening machine body 1, thereby holding the first insert rod 13 and the second insert rod 16 respectively. The circular through grooves opened on the surface of the side blocks 14 are inserted into the circular through grooves opened on the surface of the limiting rod 12 until the threaded head 15 on the surface of the first insert rod 13 abuts against the threaded groove on the surface of the second insert rod 16, thereby connecting the two and rotating the first insert rod 13 so that the threaded head 15 at its front end is threadedly connected to the second insert rod 16, thereby fixing the baffle 10 at the top of the screening machine body 1. At this time, the baffle 10 abuts against the top of the screen 6, restricting its position. The feed hopper 11 connected to the top of the baffle 10 facilitates the feeding of the ore raw materials to be screened. While the feed hopper 11 is feeding, the motor installed on the surface of the screening machine body 1 is started to run, thereby driving the screen 6 to vibrate and screen the ore raw materials on it. When the ore raw materials on the screen 6 are vibrating and screening, the baffle 10 at the top of it blocks the splashed ore to prevent it from splashing out and causing injury to the workers. After long-term use, the side block 14 and the second insert rod 16, which are threaded together, can be unscrewed periodically to pull out the first insert rod 13 and the second insert rod 16 inserted into the limiting rod 12. The above operation can then be repeated to rotate and flip the baffle 10 to expose the bottom screen 6, which can then be disassembled and replaced.

[0027] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
