[0003] When powdered calcium oxide is granulated, calcium oxide powder and other necessary ingredients (such as binders or other additives) are weighed and mixed according to the formula requirements to ensure uniform mixing, and the uniformly mixed materials are sent to the roller extrusion granulator for extrusion molding. For example, a powder drying granulation device disclosed in the existing Chinese utility model patent (CN221772208U) puts the powder into the granulation box through the feed port, and the two granulation rollers rotate in opposite directions to extrude the powder. Since the surface of the granulation roller is provided with spherical grooves, the powder will form particles after being extruded, and the powder formed into particles enters the trimming box through the guide ring 2.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

When the auxiliary forming block 105 moves to the bottom of the squeezing roller 103, under the guidance of the guide groove 104, the telescopic mechanism 3 drives the auxiliary forming block 105 to extend out of the guide groove 104; the auxiliary forming block 105 is provided with an arc groove 106, and the side wall of the squeezing roller 103 is provided with an arc groove 2 107, and the arc groove 106 and the arc groove 107 are connected to each other. Groove 2 107 forms a semicircular groove on the side wall of the extrusion roller 103, and the semicircular grooves on the side walls of the two extrusion rollers 103 form a complete granulation extrusion space. The arc groove 1 106 and the arc groove 2 107 are both provided in plurality. A hopper 108 is fixed to the upper end of the shell 102, and a protective net 109 is fixed inside the hopper 108. A mounting frame 110 is fixed obliquely below the workbench 101, and a filter net 111 is fixed on the mounting frame 110.

[0022] In the embodiment of the present invention, when in use, powdered calcium oxide is put into the hopper 108, and 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 squeezing rollers 103, and the powdered calcium oxide enters the semicircular troughs on the side walls of the two squeezing rollers 103. The opposite driving mechanism 2 drives the two squeezing rollers 103 to rotate synchronously in opposite directions. The two squeezing rollers 103 drive the semicircular troughs on each of them to move. The semicircular troughs on the two squeezing rollers 103 squeeze the powdered calcium oxide until the semicircular troughs on the two squeezing rollers 103 overlap, and then squeeze the powdered calcium oxide into particles. As the two squeezing rollers 103 continue to rotate, the two semicircular troughs rotate to the bottom of the squeezing rollers 103 and separate, forming The particles fall from the semicircular trough. When the auxiliary forming block 105 moves to the bottom of the extrusion roller 103, under the guiding action of the guide groove 104, the telescopic mechanism 3 drives the auxiliary forming block 105 to extend out of the guide groove 104, and the auxiliary forming block 105 pushes out the particles stuck in the semicircular trough, thereby allowing the particles in the semicircular trough to be smoothly withdrawn, thereby improving the efficiency of powdered calcium oxide granulation. When the auxiliary forming block 105 is away from the bottom of the extrusion roller 103, under the guiding action of the guide groove 104, the telescopic mechanism 3 drives the auxiliary forming block 105 to retract into the guide groove 104, and the arc shape of the auxiliary forming block 105 coincides with the axis of the extrusion roller 103, thereby completing a working cycle, and the formed particles fall on the inclined filter screen 111, and the debris in the particles is separated by the filter screen 111.

[0023] like Figure 1 and Figure 2 As 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 shell 102, a motor 202 is fixed on the support frame 201, the rotating end of the motor 202 is fixedly connected to one of the squeezing rollers 103, and gears 203 are fixed on both of the squeezing rollers 103, and the two gears 203 are meshed.

[0024] In the embodiment of the present invention, the motor 202 drives one of the squeezing rollers 103, one of the squeezing rollers 103 drives one of the gears 203 to rotate, one of the gears 203 drives the other gear 203 to reverse, and the other gear 203 drives the other squeezing roller 103 to reverse, thereby realizing that the two squeezing rollers 103 rotate in opposite directions.

[0025] like Figure 1-11As shown, as a preferred embodiment of the present invention, the telescopic mechanism 3 includes a tension spring 301 fixed on one side of the auxiliary forming block 105 close to the axis of the squeezing roller 103, the tension spring 301 is fixed in the guide groove 104, and a driving shaft 302 is fixed at both ends of the auxiliary forming block 105. A plurality of avoidance holes 303 are evenly arranged in an annular shape at both ends of the squeezing roller 103, and the driving shaft 302 extends from the end of the squeezing roller 103 through the avoidance holes 303. A fixing block 304 is fixed on the side wall of the shell 102, and a pushing protrusion 305 is fixed on one end of the fixing block 304 close to the shell 102.

[0026] In the embodiment of the present invention, in the initial state, under the guiding action of the guide groove 104, the tension spring 301 pulls the auxiliary forming block 105, and the auxiliary forming block 105 shrinks in the guide groove 104. The arc groove 106 and the arc groove 2 107 form a semicircular groove on the side wall of the squeezing roller 103. When the auxiliary forming block 105 moves to the bottom of the squeezing roller 103 and the pushing protrusion 305 contacts the pushing shaft 302, as the squeezing 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 guide 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 guide groove 104. The arc groove 1 106 and the arc groove 2 107 on the auxiliary forming block 105 are misaligned. By misaligning the arc groove 106 and the arc groove 2 107, the particles are pushed out from the semicircular trough, thereby assisting the withdrawal of the particles in the semicircular trough. 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 opposite direction and reset.

[0027] like Figure 1-Figure 11 As shown, as a preferred embodiment of the present invention, a plurality of push protrusions 305 are fixed on the fixing block 304, and the plurality of push protrusions 305 are evenly arranged in an arc track.

[0028] In the embodiment of the present invention, by setting a plurality of pushing protrusions 305, the auxiliary forming block 105 can be pushed out of the guide groove 104 multiple times, and then the auxiliary forming block 105 can be vibrated by multiple extension and contraction, thereby preventing particles from being stuck in the arc groove 106, and further promoting the withdrawal of particles.

[0029] like Figure 1-Figure 12 As shown, as a preferred embodiment of the present invention, a U-shaped auxiliary reset frame 306 is fixed on the side wall of the shell 102, and a U-shaped push groove is arranged on the inner side of the U-shaped auxiliary reset frame 306. The middle part of the U-shaped push groove is semicircular. When the push shaft 302 contacts the semicircular part of the U-shaped push groove, the arc shape of the auxiliary forming block 105 coincides with the axis of the extrusion roller 103.

[0030] 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.

[0031] like Figure 1-Figure 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.

[0032] 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.

[0033] The above embodiment of the present invention provides an intelligent granulation production equipment for powdered calcium oxide. When in 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 is accumulated on the two squeezing rollers 103. The powdered calcium oxide enters the semicircular sink grooves on the side walls of the two squeezing rollers 103. The motor 202 drives one of the squeezing rollers 103, and one of the squeezing rollers 103 drives one of the gears 203 to rotate. One of the gears 203 drives the other gear 203 to reverse, and the other gear 203 drives the other squeezing roller 103 to reverse, thereby realizing the two squeezing rollers 1 03 rotates in opposite directions, and the two squeezing rollers 103 drive the semicircular grooves on each of them to move, and the semicircular grooves on the two squeezing rollers 103 squeeze the powdered calcium oxide until the semicircular grooves on the two squeezing rollers 103 overlap, thereby squeezing the powdered calcium oxide into particles. As the two squeezing rollers 103 continue to rotate, the two semicircular grooves rotate to the bottom of the squeezing rollers 103 and separate, and the formed particles fall from the semicircular grooves. When the auxiliary forming block 105 moves to the bottom of the squeezing roller 103 and pushes the protrusion 305 to contact the driving shaft 302, as the squeezing roller 103 drives the auxiliary forming block 105 and the driving shaft 302 to rotate The pushing protrusion 305 pushes the pushing shaft 302. Under the guiding action of the guide 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 guide groove 104. The arc groove 1 106 and the arc groove 2 107 on the auxiliary forming block 105 are misaligned. By misaligning the arc groove 106 and the arc groove 2 107, the particles are pushed out from the semicircular sinking groove, thereby assisting the withdrawal of the particles in the semicircular sinking 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 opposite direction and reset. By setting a plurality of pushing protrusions 305, the auxiliary forming block 105 can be pushed out multiple times. The guide groove 104, and then the auxiliary forming block 105 is vibrated by multiple extension and retraction, so as to avoid the particles from being stuck in the arc groove 106, further promoting the withdrawal of the particles, thereby improving the efficiency of powdered calcium oxide granulation. 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, and 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, thereby completing a working cycle, and the formed particles fall on the inclined filter screen 111, and the debris in the particles is separated by the filter screen 111.
