Description

Technical Field

[0001] This utility model relates to the field of engineering and experimental equipment technology, specifically to a batching device for calcium carbonate production. Background Technology

[0002] In the calcium carbonate production process, the batching process is one of the key links affecting product quality. Traditional calcium carbonate batching equipment usually adopts a simple stirring and conveying structure, such as a single-shaft agitator combined with a screw conveyor, but some problems still exist.

[0003] Conventional stirring shafts are prone to material accumulation or dead zones in the feed tank, resulting in uneven mixing of calcium carbonate with other raw materials, such as additives and fillers, which affects subsequent reactions or product quality. Furthermore, the connection between the stirring shaft and the conveying shaft is usually made of rigid couplings or keyways, which are prone to loosening, slippage, or wear after long-term operation, leading to a decrease in power transmission efficiency and even affecting continuous production. Therefore, a batching device for calcium carbonate production is proposed to address the above issues. Utility Model Content

[0004] The purpose of this invention is to provide a batching device for calcium carbonate production.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a batching device for calcium carbonate production, comprising a feeder and a discharger. The feeder includes a feeding hopper, the top of which is rotatably connected to a stirring shaft. The discharger includes a stirring hopper, the bottom of which is rotatably connected to a double spiral shaft. The top of the double spiral shaft is connected to a feed inlet via a fixing assembly. The feeder and discharger are connected by a flange. The fixing assembly includes a conical column and a conical sleeve. A ring of wedge-shaped protrusions is provided on the outer surface of the conical column. A wedge-shaped hole is opened on the inner side of the conical sleeve, and the wedge-shaped protrusions cooperate with the wedge-shaped hole. A cylindrical sleeve is provided at the bottom of the conical sleeve, and the cylindrical sleeve is located at the upper end of the double spiral shaft.

[0007] Furthermore, a sealing cover is provided on the top of the feeding hopper, and a hole is opened on the sealing cover, through which a stirring shaft is installed.

[0008] Furthermore, the sealing cap is also provided with a feed inlet, which is connected to a feed pipe.

[0009] Furthermore, the discharge device also includes a support, on which a mixing tank is fixedly installed. The bottom of the mixing tank is also provided with a hole, and a discharge pipe is installed in the hole.

[0010] Furthermore, two fixing plates are fixedly installed at the bottom of the tapered column, and each fixing plate has a bolt at its outer end. The bottom end of the tapered sleeve has a screw hole, and the bolt and screw hole are matched.

[0011] Furthermore, the wedge-shaped bumps are distributed in a stepped pattern.

[0012] This utility model has the following beneficial effects:

[0013] This utility model improves the connection stability of the drive shaft through the structural design of the fixed component, the precise engagement of the stepped wedge-shaped protrusions and wedge-shaped holes, and the quick disassembly and assembly function is realized through the bolt fixing structure at the bottom. When maintenance or replacement of parts is required, the tapered sleeve can be separated simply by loosening the bolts, without disassembling the entire transmission system, thus reducing maintenance difficulty and time cost.

[0014] This utility model, through the structural design of the feeder and discharger, combines the feeder's stirring shaft with the discharger's double spiral shaft to form a dual stirring system. The upper stirring shaft prevents raw materials from accumulating at the feed inlet, ensuring uniform initial mixing; the lower double spiral shaft performs secondary mixing during the conveying process, completely eliminating mixing dead zones and improving the quality stability of the final product. The flange connection allows the two stirring systems to work together or be maintained independently, balancing production efficiency and equipment maintainability.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] Please see Figure 1-4 This utility model provides a technical solution: a batching device for calcium carbonate production, including a feeder 1 and a discharger 2, which are connected by a flange. The feeder 1 includes a feeding bucket 101, and a stirring shaft 103 is rotatably connected to the top of the feeding bucket 101. A sealing cover 102 is also provided on the top of the feeding bucket 101. A hole is opened on the sealing cover 102, and the stirring shaft 103 is arranged in the hole. A feed inlet 104 is also opened on the sealing cover 102, and the feed inlet 104 is connected to a feed pipe.

[0023] In this embodiment, the feeder 1 achieves preliminary mixing and conveying of raw materials through the feeding hopper 101 and the stirring shaft 103. The sealing cover 102 ensures sealing, and the feed inlet 104 is connected to the feed pipe to achieve continuous feeding. The discharger 2 is connected to the feeder 1 through a flange to form an integral part. The stirring hopper 201 and the double spiral shaft 202 inside it perform secondary mixing and conveying of materials. The calcium carbonate raw material powder enters the feeding hopper 101 from the feed inlet 104. After being initially mixed by the stirring shaft 103 connected to the motor shaft, it enters the stirring hopper 201. The double spiral shaft 202 further mixes and conveys it to the next process to complete the batching process.

[0024] The discharge device 2 includes a mixing tank 201, a double spiral shaft 202 is rotatably connected to the bottom of the mixing tank 201, and the top of the double spiral shaft 202 is connected to the feed inlet 104 through a fixing component 3. The discharge device 2 also includes a support 203, on which the mixing tank 201 is fixedly installed. The bottom of the mixing tank 201 is also provided with a hole, and a discharge pipe 204 is installed in the hole.

[0025] In this embodiment, the discharge device 2 realizes secondary mixing and conveying of materials through the mixing tank 201 and the double helical shaft 202. The double helical shaft 202 is connected to the feed inlet 104 through the fixing component 3 to ensure stable power transmission. The support 203 provides stable support for the mixing tank 201 to ensure smooth operation of the equipment. The discharge pipe 204 at the bottom of the mixing tank 201 is used to discharge the mixed materials. After the materials enter from the feed inlet 104, they are fully mixed in the mixing tank 201 by the rotation, stirring and propulsion of the double helical shaft 202, and finally discharged through the discharge pipe 204 to realize the discharge process.

[0026] The fixing component 3 includes a conical column 301 and a conical sleeve 302. A ring of wedge-shaped protrusions 303 is provided on the outer surface of the conical column 301. The wedge-shaped protrusions 303 are distributed in a stepped manner. A wedge-shaped hole 304 is opened on the inner side of the conical sleeve 302. The wedge-shaped protrusions 303 cooperate with the wedge-shaped hole 304. A cylindrical sleeve 305 is provided at the bottom of the conical sleeve 302. The cylindrical sleeve 305 is located at the upper end of the double helical shaft 202. Two fixing plates 306 are fixedly installed at the bottom of the conical column 301. A bolt 307 is provided at the outer end of each fixing plate 306. A screw hole 308 is opened at the bottom end of the conical sleeve 302. The bolt 307 cooperates with the screw hole 308.

[0027] In this embodiment, the fixing component 3 achieves stable transmission through the wedge-shaped engagement of the tapered column 301 and the tapered sleeve 302. The stepped wedge-shaped protrusions 303 on the surface of the tapered column 301 precisely engage with the wedge-shaped holes 304 on the inner side of the tapered sleeve 302, effectively preventing transmission slippage. The cylindrical sleeve 305 connects the tapered sleeve 302 to the upper end of the double helical shaft 202. The fixing plate 306 is fastened to the screw hole 308 at the bottom end of the tapered sleeve 302 by bolts 307, ensuring reliable connection. Power is transmitted to the tapered sleeve 302 through the tapered column 301, and the transmission is achieved by utilizing the self-locking characteristics of the wedge structure. The engagement of the bolts 307 and the screw hole 308 facilitates disassembly and maintenance, ensuring transmission stability.
