Description

Technical Field

[0001] This utility model relates to the field of calcium carbonate processing, and in particular to a drying device for calcium carbonate production. Background Technology

[0002] Calcium carbonate granules are an over-the-counter medication, primarily taken by dissolving them in warm water. They supplement the body's calcium needs and can be used to prevent and treat diseases caused by calcium deficiency. In the calcium carbonate processing and production process, the raw material needs to be crushed into granules of the required size, then washed, dried, and stored.

[0003] Chinese patent publication number "CN 209877583" discloses a two-stage dryer for drying wet nano-calcium carbonate material. The dryer uses a drying box to initially heat and dry the wet nano-calcium carbonate material, and then uses a blower box to perform a second drying of the wet nano-calcium carbonate material.

[0004] Existing drying equipment for calcium carbonate production only uses heat-conducting plates connected to electric heating devices to transfer heat to the drying chamber, which suffers from low thermal conductivity. Secondly, the cold air generated by the blower box is less effective than hot air in drying the calcium carbonate material. Summary of the Invention

[0005] The main objective of this invention is to provide a drying device for calcium carbonate production, in order to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model proposes a drying device for calcium carbonate production, comprising: a support frame;

[0016] In an optional embodiment, the drying equipment for calcium carbonate production further includes a baffle plate detachably mounted on a base plate and abutting against the discharge port.

[0017] In an optional embodiment, the drying equipment for calcium carbonate production further includes a hopper connected to the feed inlet.

[0037] Reference Figures 1-3 This utility model proposes a drying device 100 for calcium carbonate production.

[0038] In this embodiment of the invention, the drying equipment 100 for calcium carbonate production includes a support 1, a drying chamber 2, a heating device 3, a blower 4, and a heat-conducting plate 5. The drying chamber 2 is mounted on the support 1 and has a drying cavity 201. The top plate 202 of the drying chamber 2 has a feed inlet 203 that communicates with the drying cavity 201. The heating device 3 is disposed inside the drying cavity 201 and has a heating cavity 301. The blower 4 communicates with the heating cavity 301. The heat-conducting plate 5 is disposed inside the drying cavity 201 and connected to the heating device 3. It has a heat-conducting groove 501 that penetrates the heat-conducting plate 5 and communicates with the heating cavity 301 and the drying cavity 201. In the direction from the top plate 202 to the heat-conducting plate 5, the heat-conducting plate 5 is inclined away from the top plate 202.

[0039] Specifically, the portion of the drying chamber 2 above the bottom plate 204 is rectangular, while the bottom plate 204 is conical, such as a cone or a square pyramid. The top plate 202 is located at the top of the drying chamber 2, and the bottom plate 204 is located at the bottom. The side wall 205 connects the top plate 202 and the bottom plate 204. Calcium carbonate particles enter the drying chamber 201 through the feed inlet 203 and fall onto the heat-conducting plate 5, where they are tumbled, baked, and subjected to airflow before finally falling onto the bottom plate 204, thus completing the drying process for the calcium carbonate particles.

[0040] The heat-conducting plate 5 is connected to the heating device 3 and transfers the heat generated by the heating device 3 to the drying chamber 201 to dry the calcium carbonate particles. A heat-conducting groove 501 is opened in the heat-conducting plate 5 to connect the heating chamber 301 and the drying chamber 201. The blower 4 blows air into the heating chamber 301 to improve the heat transfer efficiency and turn the drying air generated by the blower 4 into hot air, thereby improving the drying effect of the drying equipment 100 used for calcium carbonate production and increasing the energy utilization rate.

[0041] Refer to Figure 1 and Figure 2 In one embodiment of this utility model, a plurality of through holes 502 are provided on the side of the heat-conducting plate 5 near the top plate 202, and the plurality of through holes 502 are respectively connected to the heat-conducting groove 501. The plurality of through holes 502 are arranged opposite to the feed inlet 203. When the calcium carbonate particles tumble on the heat-conducting plate 5, the drying air blown out from the plurality of through holes 502 at the same time intensifies the tumbling of the calcium carbonate particles, further improves the drying effect, and also prevents the calcium carbonate particles from accumulating on the heat-conducting plate 5. The number of through holes 502 can be determined according to the size of the drying oven 2 and the heat-conducting plate 5.

[0042] Refer to Figure 1 In one embodiment of this utility model, the heating device 3 includes a housing 302 and a heater 303. The housing 302 has a heating chamber 301 and is mounted on the side wall 205 of the drying oven 2.

The heater 303 is arranged along the direction from the drying chamber 201 to the top plate 202. The heat-conducting plate 5 is connected to the housing 302, and the heat generated by the heater 303 is transferred to the heating chamber 301 through the housing 302 and the heat-conducting groove 501.

[0043] Refer to Figure 1 and Figure 3 In one embodiment of this utility model, the top plate 202 is provided with an air duct assembly 206, which is connected to the heating chamber 301; the blower device 4 includes a blower 401 and a blower pipe 402, the blower pipe 402 is connected to the air duct assembly 206, and the blower 401 is connected to the blower pipe 402. The blower 401 generates drying air, which enters the heating chamber 301 through the air duct assembly 206 for heating and becomes hot air, and then enters the drying chamber 201 through the heat conduction groove 501 to dry the calcium carbonate particles, thereby improving the heat transfer efficiency.

[0044] Refer to Figure 1In one embodiment of this utility model, the bottom plate 204 of the drying chamber 2 has a discharge port 207, and the bottom plate 204 is arranged opposite to the top plate 202. The dried calcium carbonate particles can be conveyed to the outside of the drying chamber 2 through the discharge port 207. To prolong the drying time of the calcium carbonate particles in the drying chamber 201 and improve the drying quality, a drying device 100 for calcium carbonate production also includes a baffle 208, which is detachably installed on the bottom plate 204 and abuts against the discharge port 207. The baffle 208 can be detachably installed on the bottom plate 204 through connections such as threads, grooves, hinges, and snap-fits.

[0045] In one embodiment of this utility model, a drying device 100 for calcium carbonate production further includes a hopper 209, which is connected to a feed inlet 203. The hopper 209 is used to receive calcium carbonate particles, making it convenient to feed them into the drying chamber 2.

[0046] In one embodiment of this utility model, a drying device 100 for calcium carbonate production further includes another heating device 3. The two heating devices 3 have the same structure and connection method, and are arranged opposite to each other. Each outer shell 302 is connected to a plurality of heat-conducting plates 5, which are arranged adjacent to each other. The number of heat-conducting plates 5 can be determined according to the size of the drying chamber 2 or the actual drying requirements.

[0047] The calcium carbonate particles tumble on several heat-conducting plates 5 arranged opposite to each other and adjacent to each other, which prolongs the tumbling time and drying time of the calcium carbonate particles in the drying chamber 201, and can further improve the drying effect.

[0048] Refer to Figure 1 and Figure 3 In one embodiment of this utility model, the air duct assembly 206 includes a first air duct 2061 and two second air ducts 2062. The first air duct 2061 extends through the top plate 202 in a direction perpendicular to the top plate 202 and the drying chamber 201, and a plug is installed at both ends of the first air duct 2061. One of the second air ducts 2062 connects the first air duct 2061 to a heating chamber 301, and the other second air duct 2062 connects the first air duct 2061 to another heating chamber 301. A blower pipe 402 is installed on the side of the top plate 202 away from the drying chamber 201 and is connected to the first air duct 2061.

[0049] Refer to Figure 1 and Figure 2In one embodiment of this utility model, in the direction from the plurality of through holes 502 to the heat-conducting groove 501, the size of the heat-conducting groove 501 is greater than the diameter of the plurality of through holes 502. The size of the heat-conducting groove 501 in the direction from the plurality of through holes 502 to the heat-conducting groove 501 is the same as the height of the heat-conducting groove 501. The height of the heat-conducting groove 501 is greater than the diameter of the through holes 502 to prevent calcium carbonate particles from entering the heat-conducting groove 501 through the through holes 502 and clogging the heat-conducting groove 501.

[0050] In the specific application of this application, the heat-conducting plate 5 is connected to the heating device 3 to transfer the heat generated by the heating device 3 to the drying chamber 201 for drying calcium carbonate particles. A heat-conducting groove 501 is opened in the heat-conducting plate 5 to connect the heating chamber 301 and the drying chamber 201. The blower 4 blows air into the heating chamber 301 to improve the heat transfer efficiency from the heating device 3 to the heat-conducting plate 5 and the drying chamber 201, and turns the drying air generated by the blower 4 into hot air, thereby improving the drying efficiency of the drying equipment 100 for calcium carbonate production and improving energy utilization.

[0051] After entering the drying chamber 201 through the feed inlet 203, the calcium carbonate particles fall onto the heat-conducting plate 5, where they are tumbled, baked, and blown by air. Finally, they fall onto the bottom plate 204 and are conveyed out of the drying box 2 through the discharge outlet 207, thus completing the drying operation of the calcium carbonate particles.
