Description

Technical Field

[0001] The present invention belongs to the technical field of calcium oxide granulation, and particularly relates to an intelligent granulation production device and granulation process for powdered calcium oxide. Background Art

[0002] The main functions of granulating powdered calcium oxide include enhancing its water solubility resistance, facilitating storage and manufacturing, increasing the application ambient temperature, maintaining the stability of high-temperature characteristics, and reducing the need for re-grinding. Through the granulation process, a dense shell layer is formed on the surface of calcium oxide particles during the calcination process, thus significantly enhancing its water solubility resistance.

[0003] When granulating powdered calcium oxide, the calcium oxide powder and other necessary components (such as binders or other additives) are weighed and mixed according to the formula requirements to ensure uniform mixing. The uniformly mixed material is then fed into a pair-roll extrusion granulator for extrusion molding. For example, a powder drying and granulating device disclosed in the existing Chinese utility model patent (CN221772208U) puts the powder into the granulating box through the feed port. Two granulating rolls rotate in opposite directions to extrude the powder. Since spherical grooves are provided on the surface of the granulating rolls, the powder will form particles after being extruded. The powder that forms particles then enters the trimming box through the second diversion ring.

[0004] When the two granulating rolls rotate in opposite directions, the corresponding spherical grooves on the side walls of the two granulating rolls continuously close and open. When the two corresponding spherical grooves open, the particles fall from the two spherical grooves. In the actual granulation process, the particles are likely to adhere to the spherical grooves, which will affect the next granulation of the spherical grooves, thereby affecting the granulation efficiency of powdered calcium oxide. Summary of the Invention

[0005] The purpose of the embodiments of the present invention is to provide an intelligent granulation production device and granulation process for powdered calcium oxide, aiming to solve the problem that particles are likely to adhere to the spherical grooves and affect the next granulation of the spherical grooves.

[0006] The present invention is implemented as follows. An intelligent granulation production device for powdered calcium oxide includes a workbench and a housing fixed to the upper end of the workbench. Two horizontal extrusion rollers are rotatably connected inside the housing, and the two extrusion rollers are arranged in parallel. It further includes: an opposite driving mechanism for driving the two extrusion rollers to rotate synchronously in opposite directions; and a plurality of guiding grooves evenly arranged in a ring on the side wall of the extrusion roller, and the plurality of guiding grooves are radially arranged with the axis of the extrusion roller as the center. A plurality of auxiliary forming blocks are slidably connected in the plurality of guiding grooves. The side of the auxiliary forming block away from the axis of the extrusion roller is arc-shaped, and the diameter of the arc on the auxiliary forming block is the same as the diameter of the extrusion roller. A telescopic mechanism is arranged on the housing. In the initial state, the telescopic mechanism drives the auxiliary forming block to retract into the guiding groove, and the arc of the auxiliary forming block coincides with the axis of the extrusion roller. When the auxiliary forming block moves to the lower part of the extrusion roller, under the guiding action of the guiding groove, the telescopic mechanism drives the auxiliary forming block to extend out of the guiding groove. An arc-shaped groove one is arranged on the auxiliary forming block, and an arc-shaped groove two is arranged on the side wall of the extrusion roller. The arc-shaped groove one and the arc-shaped groove two form a semi-circular sunk groove on the side wall of the extrusion roller, and the semi-circular sunk grooves on the side walls of the two extrusion rollers form a complete granulation extrusion space. Both the arc-shaped groove one and the arc-shaped groove two are provided with a plurality of them.

[0007] In a further technical solution, a hopper is fixed to the upper end of the housing, and a protective net is fixed inside the hopper.

[0008] In a further technical solution, an installation frame is fixed obliquely below the workbench, and a filter net is fixed on the installation frame.

[0009] In a further technical solution, the opposite driving mechanism includes a support frame fixed to the side wall of the housing. A motor one is fixed on the support frame, and the rotating end of the motor one is fixedly connected to one of the extrusion rollers. Gears are fixed on both of the two extrusion rollers, and the two gears are meshed.

[0010] In a further technical solution, the telescopic mechanism includes a tension spring fixed to the side of the auxiliary forming block close to the axis of the extrusion roller. The tension spring is fixed in the guiding groove. Push shafts are fixed to both ends of the auxiliary forming block. A plurality of avoidance holes are evenly arranged in a ring at both ends of the extrusion roller. The push shafts extend out from the ends of the extrusion roller through the avoidance holes. A fixed block is fixed to the side wall of the housing, and a push protrusion is fixed to one end of the fixed block close to the housing.

[0011] In a further technical solution, a plurality of push protrusions are fixed on the fixed block, and the plurality of push protrusions are evenly arranged in an arc-shaped track.

[0012] Further technical solution: A U-shaped auxiliary reset frame is fixed on the side wall of the housing. A U-shaped push groove is arranged inside the U-shaped auxiliary reset frame. The middle part of the U-shaped push groove is semi-circular. When the push shaft contacts the semi-circular part of the U-shaped push groove, the arc of the auxiliary forming block coincides with the axis of the extrusion roller.

[0013] Further technical solution: A crushing mechanism is arranged inside the housing. The crushing mechanism includes two rotating shafts rotatably connected inside the housing. The two rotating shafts are arranged in parallel. The two rotating shafts are located below the two extrusion rollers. A plurality of crushing rods are installed on each of the two rotating shafts. The crushing rods on the two rotating shafts are arranged staggeredly. A synchronous driving component is arranged on the housing. The synchronous driving component is used to drive the two rotating shafts to rotate synchronously in the same direction.

[0014] Further technical solution: The synchronous driving component includes a second motor fixed on the side wall of the housing. The rotating end of the second motor is fixedly connected to one of the rotating shafts. Synchronous belt pulleys are fixedly installed on each of the two rotating shafts. The two synchronous belt pulleys are connected by a synchronous belt.

[0015] A granulation process for powdered calcium oxide:

[0016] Step 1: Put the powdered calcium oxide between the two extrusion rollers. The powdered calcium oxide enters the semi-circular sinking grooves on the side walls of the two extrusion rollers.

[0017] Step 2: The opposite driving mechanism drives the two extrusion rollers to rotate synchronously in opposite directions. The two extrusion rollers drive the opposite semi-circular sinking grooves on them to move. The opposite semi-circular sinking grooves on the two extrusion rollers extrude the powdered calcium oxide until the opposite semi-circular sinking grooves on the two extrusion rollers coincide, and then the powdered calcium oxide is extruded into particles.

[0018] Step 3: As the two extrusion rollers continue to rotate, the two opposite semi-circular sinking grooves rotate to the lower part of the extrusion rollers and separate. The formed particles fall out of the semi-circular sinking grooves.

[0019] Step 4: When the auxiliary forming block moves to the lower part of the extrusion roller, under the guiding action of the guiding groove, the telescopic mechanism drives the auxiliary forming block to extend out of the guiding groove. The auxiliary forming block pushes out the particles stuck in the semi-circular sinking groove.

[0020] Compared with the prior art, the beneficial effects of the present invention:

[0021] 1. When the auxiliary forming block moves to the lower part of the extrusion roller, under the guiding action of the guiding groove, the telescopic mechanism drives the auxiliary forming block to extend out of the guiding groove. The auxiliary forming block pushes out the particles stuck in the semi-circular sinking groove, thereby enabling the particles in the semi-circular sinking groove to be smoothly discharged, and thus improving the granulation efficiency of the powdered calcium oxide.

[0022] 2. By setting multiple pushing protrusions, the auxiliary forming block can be pushed out of the guiding groove multiple times, and then vibration can be achieved by the way of multiple expansions and contractions of the auxiliary forming block, so as to shake off the particles, thereby avoiding the particles being stuck in the first arc groove and further promoting the discharging of the particles;

[0023] 3. When the tension spring is used for a long time and its elasticity weakens and it cannot pull the auxiliary forming block to completely retract into the guiding groove, the U-shaped pushing groove pushes the pushing shaft to move, and the pushing shaft drives the auxiliary forming block to retract into the guiding groove, so as to force the auxiliary forming block to retract into the guiding groove and avoid damage caused by continued granulation when the auxiliary forming block protrudes and presses the roller.

Specific embodiments

[0037] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0039] As Figures 1-8As shown in the figure, a kind of intelligent granulation production equipment for powdered calcium oxide provided by an embodiment of the present invention includes a workbench 101 and a housing 102 fixed to the upper end of the workbench 101. Two horizontal extrusion rollers 103 are rotatably connected in the housing 102, and the two extrusion rollers 103 are arranged in parallel. It also includes: an opposite driving mechanism 2 for driving the two extrusion rollers 103 to rotate synchronously in opposite directions; and a plurality of guiding grooves 104 uniformly arranged in a ring on the side wall of the extrusion roller 103. The plurality of guiding grooves 104 are radially arranged with the axis of the extrusion roller 103 as the center. A plurality of auxiliary forming blocks 105 are slidably connected in the plurality of guiding grooves 104. The side of the auxiliary forming block 105 away from the axis of the extrusion roller 103 is arc-shaped, and the diameter of the arc on the auxiliary forming block 105 is the same as the diameter of the extrusion roller 103. A telescopic mechanism 3 is arranged on the housing 102. In the initial state, the telescopic mechanism 3 drives the auxiliary forming block 105 to retract into the guiding groove 104, and the arc of the auxiliary forming block 105 coincides with the axis of the extrusion roller 103. When the auxiliary forming block 105 moves to the lower part of the extrusion roller 103, under the guiding action of the guiding groove 104, the telescopic mechanism 3 drives the auxiliary forming block 105 to extend out of the guiding groove 104. An arc-shaped groove 106 is arranged on the auxiliary forming block 105, and an arc-shaped groove 107 is arranged on the side wall of the extrusion roller 103. The arc-shaped groove 106 and the arc-shaped groove 107 form a semi-circular sunk groove on the side wall of the extrusion roller 103. The semi-circular sunk grooves on the side walls of the two extrusion rollers 103 form a complete granulation extrusion space. A plurality of the arc-shaped groove 106 and the arc-shaped groove 107 are arranged. A hopper 108 is fixed to the upper end of the housing 102, and a protective net 109 is fixed in the hopper 108. An installation frame 110 is obliquely fixed under the workbench 101, and a filter net 111 is fixed on the installation frame 110.

[0040] In an embodiment of the present invention, during use, powdered calcium oxide is put into the hopper 108. The protective net 109 in the hopper 108 is used to prevent impurities from entering the hopper 108. The powdered calcium oxide accumulates on the two extrusion rollers 103. The powdered calcium oxide enters the semi-circular grooves on the side walls of the two extrusion rollers 103. The opposite driving mechanism 2 drives the two extrusion rollers 103 to rotate synchronously in opposite directions. The two extrusion rollers 103 drive the opposite semi-circular grooves on their respective sides to move. The opposite semi-circular grooves on the two extrusion rollers 103 extrude the powdered calcium oxide until the opposite semi-circular grooves on the two extrusion rollers 103 coincide, and then the powdered calcium oxide is extruded into particles. As the two extrusion rollers 103 continue to rotate, the two opposite semi-circular grooves rotate to the lower part of the extrusion rollers 103 and separate. The formed particles fall out of the semi-circular grooves. When the auxiliary forming block 105 moves to the lower part of the extrusion rollers 103, under the guiding action of the guiding groove 104, the telescopic mechanism 3 drives the auxiliary forming block 105 to extend out of the guiding groove 104. The auxiliary forming block 105 pushes out the particles stuck in the semi-circular grooves, so that the particles in the semi-circular grooves are smoothly discharged, thereby improving the granulation efficiency of the powdered calcium oxide. When the auxiliary forming block 105 moves away from the lower part of the extrusion rollers 103, under the guiding action of the guiding groove 104, the telescopic mechanism 3 drives the auxiliary forming block 105 to retract into the guiding groove 104. The arc of the auxiliary forming block 105 coincides with the axis of the extrusion rollers 103, thus completing a working cycle. The formed particles fall on the inclined filter screen 111, and the filter screen 111 separates the debris in the particles.

[0041] As Figure 1 and Figure 2 shown, as a preferred embodiment of the present invention, the opposite driving mechanism 2 includes a support frame 201 fixed on the side wall of the housing 102. A first motor 202 is fixed on the support frame 201. The rotating end of the first motor 202 is fixedly connected to one of the extrusion rollers 103. Gears 203 are fixed on both of the two extrusion rollers 103, and the two gears 203 are meshed.

[0042] In an embodiment of the present invention, the first motor 202 drives one of the extrusion rollers 103. One of the extrusion rollers 103 drives one of the gears 203 to rotate. One of the gears 203 drives the other gear 203 to rotate in the reverse direction. The other gear 203 drives the other extrusion roller 103 to rotate in the reverse direction, thereby realizing the rotation of the two extrusion rollers 103 in opposite directions.

[0043] As Figures 1-11As shown, as a preferred embodiment of the present invention, the telescopic mechanism 3 includes a tension spring 301 fixed to the side of the auxiliary forming block 105 close to the axis of the extrusion roller 103. The tension spring 301 is fixed in the guiding groove 104. Both ends of the auxiliary forming block 105 are fixed with a pushing shaft 302. A plurality of avoiding holes 303 are evenly arranged in a circular shape at both ends of the extrusion roller 103. The pushing shaft 302 extends out from the end of the extrusion roller 103 through the avoiding hole 303. A fixing block 304 is fixed on the side wall of the housing 102, and a pushing protrusion 305 is fixed to the end of the fixing block 304 close to the housing 102.

[0044] In the embodiment of the present invention, in the initial state, under the guiding action of the guiding groove 104, the tension spring 301 pulls the auxiliary forming block 105, and the auxiliary forming block 105 retracts into the guiding groove 104. The first arc groove 106 and the second arc groove 107 form a semi-circular sunk groove on the side wall of the extrusion roller 103. When the auxiliary forming block 105 moves to the lower part of the extrusion roller 103 and the pushing protrusion 305 contacts the pushing shaft 302, as the extrusion roller 103 drives the auxiliary forming block 105 and the pushing shaft 302 to rotate, the pushing protrusion 305 pushes the pushing shaft 302. Under the guiding action of the guiding groove 104, the pushing shaft 302 overcomes the elastic force of the tension spring 301 and drives the auxiliary forming block 105 to extend out of the guiding groove 104. The first arc groove 106 on the auxiliary forming block 105 is misaligned with the second arc groove 107. In the way that the first arc groove 106 is misaligned with the second arc groove 107, the particles are pushed out of the semi-circular sunk groove, thereby assisting in the discharging of the particles in the semi-circular sunk groove. After the pushing shaft 302 is no longer in contact with the pushing protrusion 305, the tension spring 301 pulls the auxiliary forming block 105 to move in the reverse direction and reset.

[0045] As Figures 1-11 shown, as a preferred embodiment of the present invention, a plurality of pushing protrusions 305 are fixed on the fixing block 304, and the plurality of pushing protrusions 305 are evenly arranged in an arc track.

[0046] In the embodiment of the present invention, by arranging a plurality of pushing protrusions 305, the auxiliary forming block 105 can be pushed to extend out of the guiding groove 104 multiple times. Furthermore, vibration is realized by the multiple telescopic movements of the auxiliary forming block 105, thereby preventing the particles from getting stuck in the first arc groove 106 and further promoting the discharging of the particles.

[0047] As Figures 1-12 shown, as a preferred embodiment of the present invention, a U-shaped auxiliary reset frame 306 is fixed on the side wall of the housing 102. A U-shaped pushing groove is arranged inside the U-shaped auxiliary reset frame 306, and the middle part of the U-shaped pushing groove is semi-circular. When the pushing shaft 302 contacts the semi-circular part of the U-shaped pushing groove, the circular arc of the auxiliary forming block 105 coincides with the axis of the extrusion roller 103.

[0048] In an embodiment of the present invention, after the auxiliary forming block 105 is away from the bottom of the extrusion roller 103, the pushing shaft 302 enters the U-shaped pushing groove. When the tension spring 301 is used for a long time, its elasticity is weakened and it is unable to pull the auxiliary forming block 105 completely into the guide groove 104, the U-shaped pushing groove pushes the pushing shaft 302 to move, and the pushing shaft 302 drives the auxiliary forming block 105 to retract into the guide groove 104, thereby forcing the auxiliary forming block 105 to retract into the guide groove 104, avoiding damage caused by continued granulation when the auxiliary forming block 105 protrudes from the extrusion roller 103. A rotating sleeve or bearing can be installed on the pushing shaft 302 to reduce the friction between the pushing shaft 302 and the U-shaped pushing groove or the pushing protrusion 305.

[0049] like Figures 1-4 As shown, as a preferred embodiment of the present invention, a crushing mechanism 4 is arranged in the shell 102, and the crushing mechanism 4 includes two rotating shafts 401 rotatably connected in the shell 102, the two rotating shafts 401 are arranged in parallel, and the two rotating shafts 401 are located below the two squeezing rollers 103, and multiple crushing rods 402 are installed on the two rotating shafts 401, and the crushing rods 402 on the two rotating shafts 401 are staggered. A synchronous drive component 5 is arranged on the shell 102, and the synchronous drive component 5 is used to drive the two rotating shafts 401 to rotate synchronously in the same direction. The synchronous drive component 5 includes a second motor 501 fixed to the side wall of the shell 102, and the rotating end of the second motor 501 is fixedly connected to one of the rotating shafts 401, and a synchronous pulley 502 is fixed on the two rotating shafts 401, and the two synchronous pulleys 502 are connected through a synchronous belt 503.

[0050] In the embodiment of the present invention, generally, a gap is reserved between the two extrusion rollers 103. If there is no gap in the middle of the double-roll granulator, it may cause problems such as equipment overload and increased wear, thereby affecting the life and performance of the equipment; when there is a gap between the two extrusion rollers 103, there is a problem of adjacent particles being connected together. At this time, the motor 2 501 drives one of the rotating shafts 401 to rotate, and one of the rotating shafts 401 drives the other rotating shaft 401 to rotate through the synchronous pulley 502 and the synchronous belt 503, thereby rotating the two rotating shafts 401, and the two rotating rotating shafts 401 are broken together by the breaking rod 402.

[0051] In the above embodiment of the present invention, an intelligent granulation production device for powdered calcium oxide is provided. When in use, the powdered calcium oxide is put into the hopper 108. The protective net 109 in the hopper 108 is used to prevent impurities from entering the hopper 108. The powdered calcium oxide accumulates on the two extrusion rollers 103. The powdered calcium oxide enters the semi-circular grooves on the side walls of the two extrusion rollers 103. The first motor 202 drives one of the extrusion rollers 103. One of the extrusion rollers 103 drives one of the gears 203 to rotate. One of the gears 203 drives the other gear 203 to rotate in the reverse direction. The other gear 203 drives the other extrusion roller 103 to rotate in the reverse direction, thereby realizing the rotation of the two extrusion rollers 103 in opposite directions. The two extrusion rollers 103 drive the opposite semi-circular grooves on them to move. The opposite semi-circular grooves on the two extrusion rollers 103 extrude the powdered calcium oxide until the opposite semi-circular grooves on the two extrusion rollers 103 coincide, thereby extruding the powdered calcium oxide into particles. As the two extrusion rollers 103 continue to rotate, the two opposite semi-circular grooves rotate to the lower part of the extrusion rollers 103 and separate. The formed particles fall out of the semi-circular grooves. When the auxiliary forming block 105 moves to the lower part of the extrusion roller 103 and the pushing protrusion 305 contacts the pushing shaft 302, as the extrusion roller 103 drives the auxiliary forming block 105 and the pushing shaft 302 to rotate, the pushing protrusion 305 pushes the pushing shaft 302. Under the guiding action of the guiding groove 104, the pushing shaft 302 overcomes the elastic force of the tension spring 301 and drives the auxiliary forming block 105 to extend out of the guiding groove 104. The first arc groove 106 on the auxiliary forming block 105 is misaligned with the second arc groove 107. By the way of the misalignment between the first arc groove 106 and the second arc groove 107, the particles are pushed out of the semi-circular groove, thereby assisting the discharging of the particles in the semi-circular groove. After the pushing shaft 302 is no longer in contact with the pushing protrusion 305, the tension spring 301 pulls the auxiliary forming block 105 to move in the reverse direction and reset. By arranging a plurality of pushing protrusions 305, the auxiliary forming block 105 can be pushed to extend out of the guiding groove 104 multiple times, and then vibration is realized by the multiple telescopic movements of the auxiliary forming block 105, thereby preventing the particles from getting stuck in the first arc groove 106 and further promoting the discharging of the particles, thereby improving the granulation efficiency of the powdered calcium oxide. After the auxiliary forming block 105 moves away from the lower part of the extrusion roller 103, the pushing shaft 302 enters the U-shaped pushing groove. The U-shaped pushing groove pushes the pushing shaft 302 to move. The pushing shaft 302 drives the auxiliary forming block 105 to retract into the guiding groove 104, thereby forcibly retracting the auxiliary forming block 105 into the guiding groove 104, thus completing a working cycle. The formed particles fall on the inclined filter screen 111, and the filter screen 111 separates the debris in the particles.

[0052] A granulation process for powdered calcium oxide, based on the above intelligent granulation production device for powdered calcium oxide:

[0053] Step 1: Put powdered calcium oxide between two extrusion rollers 103, and the powdered calcium oxide enters the semi-circular grooves on the side walls of the two extrusion rollers 103.

[0054] Step 2: The opposite driving mechanism 2 drives the two extrusion rollers 103 to rotate synchronously in opposite directions. The two extrusion rollers 103 drive the opposite semi-circular grooves on them to move. The opposite semi-circular grooves on the two extrusion rollers 103 extrude the powdered calcium oxide until the opposite semi-circular grooves on the two extrusion rollers 103 coincide, and then the powdered calcium oxide is extruded into particles.

[0055] Step 3: As the two extrusion rollers 103 continue to rotate, the two opposite semi-circular grooves rotate to the lower part of the extrusion rollers 103 and separate, and the formed particles fall out of the semi-circular grooves.

[0056] Step 4: When the auxiliary forming block 105 moves to the lower part of the extrusion roller 103, under the guiding action of the guiding groove 104, the telescopic mechanism 3 drives the auxiliary forming block 105 to extend out of the guiding groove 104, and the auxiliary forming block 105 pushes out the particles stuck in the semi-circular grooves.

[0057] The above is only the preferred embodiment of the present invention, and it is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
