Description

Technical Field

[0001] This application relates to the field of calcium carbonate drying technology, specifically a calcium carbonate material drying device. Background Art

[0002] Calcium carbonate is a common inorganic compound, mainly existing in mineral form such as limestone, marble, and chalk. It is an important building material and industrial raw material, widely used in construction, papermaking, pharmaceuticals, food additives, and other fields.

[0003] To extend the storage time of calcium carbonate and improve its performance, drying equipment is usually used to dry the calcium carbonate material, thereby removing moisture from the calcium carbonate powder to achieve the required humidity and physical properties.

[0004] A search revealed, for example, a patent with publication number CN218565944U, which specifically discloses a uniform drying device for calcium carbonate production. This patent uses a back-and-forth moving fan to uniformly dry the calcium carbonate inside the chamber.

[0005] However, the above drying methods can cause calcium carbonate to accumulate, and the residual moisture at the bottom can lead to the formation of hydrogen bonds between calcium carbonate particles, resulting in agglomeration. This hinders the flow of heat energy, leads to uneven drying, reduces drying efficiency and effectiveness, and affects subsequent processing and use. Therefore, it is necessary to provide a calcium carbonate material drying device to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a calcium carbonate material drying device that prevents calcium carbonate from agglomerating and accumulating during the drying process, ensures the flow of heat energy, and makes the drying more uniform.

[0008] The technical solution adopted by this application to solve its technical problem is: a calcium carbonate material drying device, comprising:

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0035] like Figures 1-2As shown, this application provides a calcium carbonate material drying device, including a shell 1, in which a drying chamber 2 is fixedly installed. The shell 1 is used to keep the drying chamber 2 warm. The upper end of the drying chamber 2 is provided with a feed inlet 21, through which material is added into the drying chamber 2. At the same time, two sets of discharge plates 23 are fixedly installed at the lower end of the drying chamber 2. The two sets of discharge plates 23 are arranged at an angle to each other to form a discharge port, so that the dried material is discharged outward through the discharge plates 23.

[0036] In order to provide hot air into the drying chamber 2, a duct 4 is fixedly installed on the outer side of the middle end of the drying chamber 2. The duct 4 passes through the shell 1, and the other end of the duct 4 is connected to a hot air blower 41. The hot air blower 41 provides hot air into the duct 4. The surface of the drying chamber 2 inside the duct 4 has multiple sets of air holes 24. Therefore, the hot air enters the drying chamber 2 through the air holes 24 after it comes out of the duct 4.

[0037] like Figure 2 and Figure 4 As shown, a filter screen 22 is fixedly installed at the upper part of the interior of the drying oven 2. The filter screen 22 filters the lumpy calcium carbonate entering the drying oven 2 to prevent uneven drying of the lumpy calcium carbonate. Multiple sets of baffles 25 are provided below the filter screen 22. In this application, the air hole 24 is triangular, and the baffle 25 is also triangular and fixed on the air hole 24. Therefore, the baffle 25 guides the hot air coming out of the air hole 24, making the hot air blow downwards to prevent calcium carbonate from staying in the drying oven 2 for a long time.

[0038] It should be noted that the multiple sets of baffles 25 are arranged in a cross pattern. The baffles 25 slow down the falling speed of calcium carbonate, thus extending the drying speed of calcium carbonate and ensuring the drying effect.

[0039] like Figures 2-3 As shown, in order to prevent lumpy calcium carbonate from accumulating on the filter screen 22 and causing blockage, a pushing mechanism 3 is provided on one side of the filter screen 22. The pushing mechanism 3 has a mounting platform 31 fixedly installed on one side of the housing 1. A support frame 32 is fixedly installed at the lower end of the mounting platform 31 to support the mounting platform 31. At the same time, a turntable 33 is rotatably connected to the upper end of the mounting platform 31, and a drive motor 34 is fixedly installed at the lower end of the mounting platform 31. The output shaft of the drive motor 34 passes through the mounting platform 31 and is fixedly installed at the axis of the turntable 33. Therefore, the drive motor 34 can drive the turntable 33 to rotate.

[0040] Meanwhile, a drive rod 331 is fixedly installed at the axis of the turntable 33. The outer end of the drive rod 331 is rotatably connected to a drive rod 35. A slide rail 36 is also fixedly installed on the mounting platform 31. The slide rail 36 is located between the turntable 33 and the drying chamber 2 and passes through the housing 1. A slider 37 is slidably connected inside the slide rail 36. The end of the drive rod 35 away from the drive rod 331 is rotatably connected to the upper end of the slider 37. Therefore, when the turntable 33 rotates, it will drive the drive rod 331 to perform circular motion. The drive rod 35 will rotate accordingly and drive the slider 37 to slide horizontally inside the push rod 38.

[0041] Furthermore, a push rod 38 is fixedly installed on the side end of the slider 37. The other end of the push rod 38 is slidably connected to the drying chamber 2 and protrudes into the interior of the drying chamber 2. A push plate 39 is fixedly installed on the protruding end of the push rod 38. The push plate 39 is attached to the surface of the filter screen 22. Therefore, when the slider 37 slides inside the push rod 38, it will drive the push rod 38 and the push plate 39 to slide on the surface of the filter screen 22.

[0042] In this application, the lower end of the feeding plate 23 is also provided with a conveyor belt 5, which is used to transfer the dried material to subsequent processes.

[0043] In summary: When drying calcium carbonate, the hot air blower 41 is started first to supply hot air into the drying chamber 2. Then, the calcium carbonate to be dried is added through the feed inlet 21 until it reaches the filter screen 22. At this time, the pushing mechanism 3 is started to drive the push rod 38 and the push plate 39 to slide on the filter screen 22. During this process, the push plate 39 pushes the calcium carbonate left and right and squeezes the blocky calcium carbonate to disperse it through the filter screen 22 for drying. The push plate 39 also scrapes off the calcium carbonate adhering to the filter screen 22, thereby preventing the calcium carbonate from accumulating on the filter screen 22 and speeding up the feeding speed.

[0044] Subsequently, the calcium carbonate slowly falls through the baffle plate 25 and is finally discharged through the discharge plate 23, and falls onto the conveyor belt 5 for rotation. This prevents the calcium carbonate from clumping and accumulating during the drying process, ensures the flow of heat energy, and makes the drying more uniform, thereby improving the drying efficiency and effect and ensuring subsequent processing and use.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
