Description

Technical Field

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

[0002] Calcium carbonate has two main sources in production and daily life: one is from natural sources such as limestone and calcite in the form of lumpy calcium carbonate; the other is from calcium hydroxide solution through the generation of precipitated calcium carbonate by carbon dioxide gas. However, precipitated calcium carbonate is easily affected by external moisture during the formation process, causing it to solidify and clump together, affecting the particle distribution of calcium carbonate powder. Therefore, it needs to be de-clumped to ensure the effect of use. Most existing calcium carbonate de-clumping machines are used in conjunction with a dryer to evaporate the moisture inside the clumps, and then the clumps are cut and conveyed by a spiral cutter to achieve the de-clumping effect. However, this method only relies on the cutter to cut the clumps. Since the size of the clumps inside the calcium carbonate varies, the time required for de-clumping is not uniform. As a result, some calcium carbonate that is not completely de-clumped and becomes powder will also be discharged, resulting in poor de-clumping effect. Utility Model Content

[0003] In view of this, the present invention provides a de-agglomeration device for calcium carbonate processing, which can initially cut and crush the agglomerates through a cutting component, and after screening, the agglomerates are further crushed by a grinding component, so that the agglomerates can be completely de-agglomerated into powder before being discharged, thereby improving the de-agglomeration effect.

[0004] To solve the above-mentioned technical problems, this utility model provides a de-agglomeration device for calcium carbonate processing, including a box body, a feed pipe at the top of the box body, a discharge pipe at the bottom of the box body, and a crushing mechanism inside the box body. The crushing mechanism includes a cutting component and a grinding component. A sieve cylinder is installed inside the box body, and the cutting component is located inside the sieve cylinder. The cutting component is used to cut and crush the agglomerates, the sieve cylinder is used to screen the cut agglomerates, and the grinding component is used to further crush the screened agglomerates. The operator pours calcium carbonate agglomerates into the sieve cylinder, and the cutting component cuts the agglomerates to initially crush them. The agglomerates are crushed and passed through the sieve cylinder while being screened, and then fall into the grinding component. Finally, the grinding component grinds the agglomerates to further crush them, so that the agglomerates can be completely de-agglomerated into powder before being discharged through the discharge pipe, thereby improving the de-agglomeration effect.

[0005] The grinding assembly includes two grinding rollers that are rotatably disposed inside the lower part of the housing. The grinding assembly also includes a driving component that drives the two grinding rollers to rotate. The operator drives the two grinding rollers to rotate through the driving component, so that the two grinding rollers grind and crush the clumps, thereby achieving secondary crushing and improving the de-clumping effect.

[0006] The cutting assembly includes a support shaft rotatably mounted above the inner wall of the chamber, and the support shaft is located inside the sieve cylinder. The surface of the support shaft is provided with a spiral cutting edge. The cutting assembly also includes a rotating component, which is used to drive the support shaft to rotate. The operator drives the support shaft to rotate through the rotating component. When the support shaft rotates, the spiral cutting edge on the surface rotates to cut the lumps. After the spiral cutting edge cuts the lumps to a suitable size, the lumps will be sieved through the sieve cylinder and finally fall between two grinding rollers for secondary crushing.

[0007] The driving component includes a driving frame located below one side wall of the housing. A motor is mounted on one side of the outer wall of the driving frame, with the fixed end of the motor fixed to the side wall of the driving frame. The output end of the motor passes through the side wall of the driving frame and is equipped with a driving gear. A driven gear is rotatably mounted on one side inside the driving frame, and the driving gear and the driven gear are meshed together. The ends of the two grinding rollers pass through the inner side wall of the housing and are respectively connected to the center of the ends of the driving gear and the driven gear. When the agglomerate falls between the two grinding rollers, the motor drives the driving gear to rotate, which in turn drives the meshed driven gear to rotate. This causes the driving gear and the driven gear to drive the two grinding rollers to rotate, thereby causing the grinding rollers to perform secondary crushing of the agglomerate, grinding it into powder, and finally discharging it from the discharge pipe.

[0008] The rotating component includes a driven sprocket sleeved on the end of the support shaft. One end of the driven gear passes through the inner wall of the drive frame, and the other end of the driven gear is connected to a driving sprocket. A chain is driven between the surfaces of the driving sprocket and the driven sprocket. When calcium carbonate enters the sieve cylinder, the operator starts the motor, which drives the driving gear and the meshing driven gear to rotate. The driven gear drives the driving sprocket to rotate, and the driving sprocket drives the driven sprocket to rotate through the chain. This causes the driven sprocket to drive the support shaft to rotate, which in turn drives the spiral cutting blade to perform preliminary cutting and crushing of the agglomerates.

[0009] A drying mechanism is installed on the outer wall of the chamber. The drying mechanism includes a heating pipe sleeved on the upper side of the outer wall of the chamber, and a hot air fan installed on one side of the heating pipe. The air outlet of the hot air fan is located inside the heating pipe. The drying mechanism also includes a heating component, and the support shaft has a hollow structure. The heating component is used to transport the hot air in the heating pipe to the support shaft. Since the agglomerates contain a certain amount of moisture, before pouring calcium carbonate into the chamber, the operator can use the hot air fan to supply high-temperature air into the heating pipe. The heating pipe transfers its internal heat to the interior of the chamber to heat the interior. The heating component then transports the hot air in the heating pipe to the support shaft to heat the support shaft and the spiral cutting blade. The heat inside the chamber and the heat from the spiral cutting blade work together to make the moisture in the agglomerates evaporate faster, heating the agglomerates to a dry state. When the agglomerates are ground by the grinding roller, the dry agglomerates can be directly ground into powder, thereby improving the agglomeration effect.

[0010] The heating assembly includes an air supply pipe installed on the other side wall of the heating tube. One end of the air supply pipe penetrates the outer side wall of the housing. One end of the support shaft has a through hole. The air supply pipe extends into the cavity of the support shaft. The other end of the support shaft has an exhaust hole. After the hot air blower heats the air and delivers it into the heating tube, the hot air is delivered to the cavity of the support shaft through the air supply pipe on the other side of the heating tube, thereby heating the support shaft. The exhaust hole can discharge the hot air from the support shaft.

[0011] A sealed bearing is fitted at the end of the gas transmission pipe. The outer wall of the gas transmission pipe is fixed to the inner ring of the sealed bearing, and the outer ring of the sealed bearing is fixed to the inner wall of the through hole of the support shaft. The sealed bearing can seal the hot air in the cavity of the support shaft when the support shaft rotates, preventing heat loss.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. When using this utility model, the worker pours calcium carbonate lumps into the sieve cylinder, and the cutting component cuts the lumps to initially break them down. The lumps pass through the sieve cylinder while being broken down, and then fall into the grinding component. Finally, the grinding component grinds the lumps to further break them down, so that the lumps can be completely broken down into powder before being discharged through the discharge pipe, thus improving the breaking down effect.

[0014] 2. When this utility model is used, after the agglomerates fall between the two grinding rollers, the motor drives the drive gear to rotate, and the drive gear drives the driven gear connected to it to rotate, thereby causing the drive gear and the driven gear to drive the two grinding rollers to rotate, so that the grinding rollers can perform secondary crushing of the agglomerates, and grind the agglomerates into powder, which is finally discharged from the discharge pipe.

[0015] 3. When using this utility model, after calcium carbonate enters the sieve cylinder, the operator starts the motor, which drives the drive gear and the meshing driven gear to rotate. The driven gear drives the drive sprocket to rotate, and the drive sprocket drives the driven sprocket to rotate through the chain. This causes the driven sprocket to drive the support shaft to rotate, and the support shaft drives the spiral cutting blade to perform preliminary cutting and crushing of the agglomerates.

[0016] 4. When using this utility model, before pouring calcium carbonate into the box, the operator can use a hot air blower to supply high-temperature air into the heating pipe. The heating pipe transfers its internal heat to the inside of the box to heat the interior. The heating component then delivers the hot air from the heating pipe to the support shaft to heat the support shaft and the spiral cutting blade. The combined heat from the box and the spiral cutting blade accelerates the evaporation of moisture from the agglomerates, heating them to a dry state. When the agglomerates are ground by the grinding roller, the dry agglomerates can be directly ground into powder, thus improving the agglomeration disintegration effect. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0025] According to one embodiment of the present invention, such as Figure 1-4 As shown: This embodiment provides a de-agglomeration device for calcium carbonate processing, including a housing 100. A feed pipe 101 is provided at the upper part of the housing 100, and a discharge pipe 102 is provided at the lower part of the housing 100. A crushing mechanism is provided inside the housing 100, including a cutting component and a grinding component. A sieve cylinder 103 is provided inside the housing 100. The cutting component is located inside the sieve cylinder 103 and is used to cut and crush the agglomerates. The sieve cylinder 103 is used to screen the cut agglomerates. The grinding component is used to further crush the screened agglomerates. The operator pours calcium carbonate agglomerates into the feed pipe 101, causing the calcium carbonate to fall into the sieve cylinder 102. Inside 03, the calcium carbonate lumps inside the sieve cylinder 103 are then cut by the cutting component to initially cut and crush the lumps. During the cutting process, some lumps crushed to a suitable size can be sieved through the sieve cylinder 103 and fall into the grinding component. Other lumps inside the sieve cylinder 103 are continuously cut by the cutting component until they can be sieved through the sieve cylinder 103. Finally, they pass through the sieve holes on the surface of the sieve cylinder 103 and fall into the grinding component. The grinding component then grinds the lumps to further crush the initially crushed lumps, so that the lumps can be completely broken up into powder before being discharged through the discharge pipe 102, thus improving the de-agglomeration effect.

[0026] The grinding assembly includes two grinding rollers 300 rotatably disposed inside the lower part of the housing 100. The grinding assembly also includes a driving component, which drives the two grinding rollers 300 to rotate. The operator drives the two grinding rollers 300 to rotate through the driving component, so that the two grinding rollers 300 grind and crush the agglomerates, thereby achieving secondary crushing and improving the de-agglomeration effect.

[0027] The cutting assembly includes a support shaft 400 rotatably mounted above the inner wall of the housing 100, and the support shaft 400 is located inside the sieve cylinder 103. The surface of the support shaft 400 is provided with a spiral cutting blade 401. The cutting assembly also includes a rotating component, which is used to drive the support shaft 400 to rotate. The operator drives the support shaft 400 to rotate through the rotating component. When the support shaft 400 rotates, the spiral cutting blade 401 on its surface rotates to cut the lumps. Since the spiral cutting blade 401 is a bidirectional cutting blade, when the spiral cutting blade 401 cuts and crushes the lumps, it can transport the lumps toward the center of the spiral support shaft 400, so that the lumps on both sides are squeezed against each other, so that the spiral cutting blade 401 can cut the internal lumps more thoroughly. After the spiral cutting blade 401 cuts the lumps to a suitable size, the lumps will be screened by the sieve cylinder 103 and finally fall between the two grinding rollers 300 for secondary crushing.

[0028] The driving component includes a drive frame 301 located below one side wall of the housing 100. A motor 302 is mounted on one side of the outer wall of the drive frame 301. The fixed end of the motor 302 is fixed to the side wall of the drive frame 301. The output end of the motor 302 passes through the side wall of the drive frame 301, and a drive gear 303 is mounted on the output end of the motor 302. A driven gear 304 is rotatably mounted on one side inside the drive frame 301, and the drive gear 303 and the driven gear 304 are meshed together. The ends of both grinding rollers 300 pass through the housing 100. The inner sidewalls are respectively connected to the center of the end of the drive gear 303 and the driven gear 304. When the agglomerate falls between the two grinding rollers 300, the drive gear 303 is driven to rotate by the motor 302. The drive gear 303 drives the driven gear 304 that it meshes with to rotate, thereby causing the drive gear 303 and the driven gear 304 to drive the two grinding rollers 300 to rotate. This causes the grinding rollers 300 to perform secondary crushing on the agglomerate, so that the grinding rollers 300 grind the agglomerate into powder, which is finally discharged from the discharge pipe 102.

[0029] The rotating component includes a driven sprocket 500 sleeved on the end of the support shaft 400. One end of the driven gear 304 penetrates the inner wall of the drive frame 301, and one end of the driven gear 304 is connected to the drive sprocket 502. The drive sprocket 502 and the driven sprocket 500 are connected by a chain 501. When calcium carbonate enters the sieve cylinder 103, the operator starts the motor 302, which drives the drive gear 303 and the meshing driven gear 304 to rotate. The driven gear 304 drives the drive sprocket 502 to rotate, and the drive sprocket 502 drives the driven sprocket 500 to rotate through the chain 501. This causes the driven sprocket 500 to drive the support shaft 400 to rotate, which in turn drives the spiral cutting blade 401 to perform preliminary cutting and crushing of the agglomerates.

[0030] According to another embodiment of the present invention, such as Figure 4-6 As shown, a drying mechanism is installed on the outer wall of the box 100. The drying mechanism includes a heating tube 200 sleeved on the upper side of the outer wall of the box 100. A hot air blower 201 is installed on one side of the heating tube 200, and the air outlet of the hot air blower 201 is located inside the heating tube 200. The drying mechanism also includes a heating component, and the support shaft 400 has a hollow structure. The heating component is used to transport hot air from the heating tube 200 to the support shaft 400. Since the agglomerate contains a certain amount of moisture, before pouring calcium carbonate into the box 100, the operator can use the hot air blower 201 to supply high-temperature air into the heating tube 200. A heat-conducting pad is installed on the outer wall of the box 100 that is in contact with the heating tube 200. The heat-conducting pad can transfer the heat from the heating tube 200 to the interior of the box 100. The interior of the chamber 100 is heated, and the hot air in the heating tube 200 is delivered to the support shaft 400 through the heating component. Since the support shaft 400 and the spiral cutting blade 401 are both made of metal, the heat of the hot air can be quickly distributed to the surface of the support shaft 400 to heat the spiral cutting blade 401. After the interior of the chamber 100 and the spiral cutting blade 401 are heated to the specified temperature, calcium carbonate is poured into the chamber 100. The heat inside the chamber 100 and the heat of the spiral cutting blade 401 work together to make the moisture in the agglomerate evaporate faster and heat the agglomerate to a dry state. When the agglomerate is ground by the grinding roller 300, the dry agglomerate can be directly ground into powder to improve the agglomeration effect.

[0031] The heating assembly includes an air supply pipe 202 installed on the other side wall of the heating tube 200. One end of the air supply pipe 202 penetrates the outer side wall of the housing 100. One end of the support shaft 400 has a through hole. One end of the air supply pipe 202 penetrates the through hole at the end of the support shaft 400 and extends into the cavity of the support shaft 400. The other end of the support shaft 400 has an exhaust port 402. After the hot air blower 201 heats the air and delivers it into the heating tube 200, when the hot air passes through the air supply pipe 202 on the other side of the heating tube 200, the hot air in the heating tube 200 is delivered to the cavity of the support shaft 400 through the air supply pipe 202, thereby heating the support shaft 400. The exhaust port 402 can discharge the hot air in the support shaft 400.

[0032] A sealing bearing 203 is fitted at the end of the gas pipe 202. The outer wall of the gas pipe 202 is fixed to the inner ring of the sealing bearing 203. The outer ring of the sealing bearing 203 is fixed to the inner wall of the through hole of the support shaft 400. The sealing bearing 203 can seal the hot air in the cavity of the support shaft 400 when the support shaft 400 rotates, so as to prevent heat loss.

[0033] How to use this utility model:

[0034] When it is necessary to crush and break up calcium carbonate lumps, first start the hot air blower 201 to supply high-temperature air into the heating tube 200 to heat the inside of the heating tube 200, thereby transferring the heat from the heating tube 200 to the inside of the housing 100. At the same time, the hot air in the heating tube 200 is delivered to the support shaft 400 through the air supply pipe 202 to heat the support shaft 400 and the spiral cutting blade 401. After the spiral cutting blade 401 and the inside of the housing 100 are heated to a certain temperature, the calcium carbonate lumps are poured into the feed pipe 101, causing the lumps to fall into the screen cylinder 103. Then, start the motor 302, which drives the drive gear 303 to rotate. The drive gear 303 drives the driven gear 304, which is meshed with it, to rotate. At this time, the drive gear 303 and the driven gear 304 drive the grinding roller 300 to rotate, while the driven gear 304 drives the drive sprocket 502 to rotate. The drive sprocket 502 is connected to the chain 50 1. The driven sprocket 500 rotates, which in turn drives the support shaft 400 to rotate. During this rotation, the support shaft 400 drives the surface-heated spiral cutting blade 401 to initially cut and crush the agglomerates. The heated spiral cutting blade 401 and the heat inside the housing 100 heat the agglomerates, evaporating the moisture inside. After the spiral cutting blade 401 cuts and crushes the agglomerates to a suitable size, they pass through the sieve cylinder 103. The sieved agglomerates fall between two grinding rollers 300, where they undergo secondary crushing. This process further grinds the completely dried agglomerates into powder, which is then discharged through the discharge pipe 102. This device allows for the initial cutting and crushing of agglomerates using the cutting component, followed by secondary crushing using the grinding component after sieve cylinder 103. This ensures that the agglomerates are completely disintegrated into powder before discharge, improving the disintegration effect.

[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
