Description

Technical Field

[0001] The present invention belongs to the technical field of pulp separation equipment, and particularly relates to a semi-dry pulp separation equipment. Background Art

[0002] The fruits of plants in the Rhamnaceae family are fleshy drupes, such as jujubes and wild jujubes. Among them, wild jujubes are mainly distributed in North China. The kernels of wild jujube seeds have the effect of calming the nerves, and the husks can be used to make activated carbon, which has extremely high utilization value in the current energy conservation and environmental protection industry. For the utilization of the value of wild jujubes, the first thing to do is to separate their pulp from the pits. The traditional method is to manually knead and step on them and then wash and dry them. However, with the further development of the utilization value of wild jujubes, simply relying on manual separation can no longer meet the requirements. In this case, various pulp separation equipment have been developed in the industry.

[0003] Currently, there are two commonly used types of equipment. One is to generate extrusion force between nested rollers and make the crushed pulp discharged from the sieve holes on the outer cylinder under rotational centrifugal force to obtain the pits. The other is to use dense stirring rods to collide and beat the fruits during rotation to separate the pulp. Judging from the actual use effects, the disadvantages of the two types of equipment are that the crushed pulp is easily discharged together with the pits, and the pulp separation is not thorough; both methods need to continuously add a large amount of water during the whole separation process, with a huge water consumption; and both are limited by the equipment volume and cannot form sufficient effective working space, so the actual working efficiency is low. Therefore, there is a need to continue to develop new technologies for separating the pulp of plants in the Rhamnaceae family, especially wild jujubes, to overcome the disadvantages of the current technology.

[0027] Please refer to Figures 1 to 8, the semi-dry pulp separation equipment provided by the present invention will be described hereinafter. The semi-dry pulp separation equipment includes a frame 10, a crushing mechanism 20, a separation mechanism, and a rotary drive member 40. Among them, a main shaft 11 extending in the vertical direction is rotatably connected to the frame 10. The crushing mechanism 20 is arranged on the frame 10 and connected to the main shaft 11. The crushing mechanism 20 is provided with a first feeding port 201, a first discharging port 202, and a second discharging port 203. The crushing mechanism 20 is used for crushing the pulp of the fruit material added through the first feeding port 201, discharging the scattered pulp through the first discharging port 202, and discharging the adhesion body of the pulp and the fruit core through the second discharging port 203. The separation mechanism is arranged on the frame 10 and is located below the crushing mechanism 20. The power input end of the separation mechanism is in transmission connection with the main shaft 11. The separation mechanism is provided with a second feeding port 301, a third discharging port 302, and a fourth discharging port 303. The second feeding port 301 is connected to the second discharging port 203. Among them, the separation mechanism is used for separating the adhesion body entering through the second feeding port 301 into scattered pulp and clean fruit cores, and discharging the scattered pulp through the third discharging port 302 and the clean fruit cores through the fourth discharging port 303. The rotary drive member 40 is arranged on the frame 10, and the output end is in transmission connection with the main shaft 11.

[0028] Compared with the prior art, the semi-dry pulp separation equipment provided in this embodiment adds fruit materials to the crushing mechanism 20 through the first feeding port 201. The pulp of the fruit materials is crushed under the rolling action in the crushing mechanism 20. Among them, the scattered pulp detached from the fruit core is discharged through the first discharging port 202, and the pulp and the fruit core that are not detached from the fruit core enter the second feeding port 301 of the separation mechanism as an adhesion body. After the adhesion body enters the separation mechanism, the pulp completely detaches from the fruit core. The detached scattered pulp is discharged through the third discharging port 302, and the clean fruit cores are discharged through the fourth discharging port 303. The entire separation process goes through at least two steps of crushing and separation, which can improve the quality of pulp separation. Moreover, the crushing mechanism 20 and the separation mechanism work synchronously driven by the main shaft 11, which is beneficial to improving the efficiency of pulp separation. And the entire separation process has little dependence on water, which is beneficial to reducing the water consumption of pulp separation.

[0029] In some embodiments, refer to Figures 1 to 6, the crushing mechanism 20 includes a grinding disk 21 and a rotating disk 22; the grinding disk 21 is rotatably connected to the main shaft 11, and the bottom wall of the grinding disk 21 is provided with an annular rolling surface 211. The grinding disk 21 is in transmission connection with the main shaft 11 and reciprocates under the drive of the main shaft 11; the rotating disk 22 is fixedly sleeved on the main shaft 11 and is located below the grinding disk 21. The rotating disk 22 rotates unidirectionally under the drive of the main shaft 11; the rotating disk 22 has an annular cavity 221 that penetrates up and down. The annular cavity 221 is vertically aligned with the rolling surface 211. The top of the annular cavity 221 is provided with an annular crushing support plate 222, and the crushing support plate 222 is distributed with sieve holes 2221 suitable for broken pulp to fall through; a crushing cavity 200 is formed between the crushing support plate 222 and the rolling surface 211; wherein, the top wall of the grinding disk 21 is provided with a first feeding port 201 communicating with the crushing cavity 200, the side wall of the grinding disk 21 is provided with a second discharging port 203 communicating with the crushing cavity 200, and a first discharging port 202 communicating with the annular cavity 221 is provided below the rotating disk 22.

[0030] The fruit material enters the crushing cavity 200 from the first feeding port 201 and directly falls on the crushing support plate. Along with the rotation of the rotating disk 22, it makes a circular motion in the crushing cavity 200. At the same time, through the reciprocating swing of the grinding disk 21, the rolling surface 211 produces a rubbing effect on the fruit material, so as to break the pulp. The broken pulp that falls off from the fruit core passes through the sieve holes 2221 on the crushing support plate and then falls and is discharged from the first discharging port 202. The pulp that does not fall off and adheres to the fruit core together as an adhesion body is discharged when it rotates to the second discharging port 203, thus completing the crushing and preliminary separation of the fruit material; the crushing cavity 200 formed between the rolling surface 211 and the crushing support plate 222 is a planar annular cavity, which not only has a large cross-sectional area, is conducive to increasing the flow rate of the fruit material in and out, but also the fruit material can withstand continuous rolling and rubbing effects in the entire circumferential direction, so the crushing effect and crushing efficiency can be improved.

[0031] Specifically, in combination with Figure 3 and Figure 6 it is understood that in this embodiment, a material blocking platform 212 is provided on the rolling surface 211 at a position between the first feeding port 201 and the second discharging port 203. The adhesion body enters the second discharging port 203 under the drive of the rotating disk 22 and the guidance of the material blocking platform 212; the rolling surface 211 includes an inclined pressing surface 2111 and a flat pressing surface 2112. The inclined pressing surface 2111 gradually decreases from the first feeding port 201 along the rotation direction of the rotating disk 22, and the flat pressing surface 2112 extends from the lowest end of the inclined pressing surface 2111 along the rotation direction of the rotating disk 22 to the material blocking platform 212.

[0032] When the adhered material rotates with the turntable 22 and abuts against the material blocking table 212, with the continuous rotation of the turntable 22, the adhered material will enter the second blanking port 203 and be discharged under the blocking and guiding action of the material blocking table 212, and the discharging method is simple and stable; when the fruit material entering the crushing chamber 200 through the first feeding port 201 falls onto the crushing support plate 222, it first enters from the high end of the inclined pressing surface 2111, thus avoiding the accumulation of fruit material below the first feeding port 201. As the turntable 22 rotates, the height of the inclined pressing surface 2111 gradually decreases. During this process, the rolling and rubbing force of the inclined pressing surface 2111 on the fruit material gradually increases. At the same time, the reciprocating rotary swing of the grinding disc 21 can also avoid the accumulation of materials, ensuring that the fruit material can be flattened on the crushing support plate 222. When the fruit material is gradually crushed and enters the flat pressing surface 2112, at this time, the fruit material is continuously rubbed during the process of passing through the flat pressing surface 2112 to further improve the crushing effect; it should be understood that the interval between the flat pressing surface 2112 and the crushing support plate 222 should match the size of the fruit core to avoid crushing the fruit core. The high end of the inclined pressing surface 2111 is located below the first feeding port 201, and the interval between it and the crushing support plate 222 should be greater than the particle size of the fruit material to ensure smooth feeding.

[0033] Further, please refer to Figure 3 and Figure 5 In this embodiment, the entire rolling surface 211 should be a rough surface or a convex dot surface to ensure sufficient frictional force between the rolling surface 211 and the fruit material; the sieve holes 2221 on the crushing support plate 222 are fine strip holes, which are convenient for the scattered pulp fruits to fall. At the same time, a dot-shaped or strip-shaped convex structure 2222 is provided at the part between the crushing support plate 222 and the sieve holes 2221. On the one hand, it ensures that the fruit material can rotate with the crushing support plate 222 during the rotation of the turntable 22, and on the other hand, it can improve the crushing effect through the collision and shearing action of the convex structure 2222 on the fruit material.

[0034] It should be noted that in this embodiment, please refer to Figure 4 The frame 10 is provided with a support table 12. The bottom wall of the turntable 22 fits with the table surface of the support table 12. An area of the support table 12 aligned with the annular cavity 221 is opened to form a first blanking port 202; a plurality of support rods 223 are circumferentially and spacedly distributed in the annular cavity 221. The bottom walls of the respective support rods 223 fit with the table surface of the support table 12. The scattered pulp falling onto the support table 12 enters the first blanking port 202 under the scraping of the support rods 223.

[0035] Since there is scattered flesh separated from the fruit core in the circumferential direction of the entire crushing chamber 200, scattered flesh passes through the sieve holes 2221 on the entire annular surface of the crushing support plate 222 and drops downward onto the support table 12. Here, the support rods 223 arranged in the annular cavity 221 can scrape the scattered flesh that drops onto the support table 12 as the turntable 22 rotates. When the scattered flesh reaches the opening position of the support table 12, it is discharged from the first discharge port 202. By arranging the support rods 223 here, not only can the structural strength of the turntable 22 be improved, but also the fixed-point discharge of the scattered flesh can be achieved by means of the rotation of the turntable 22. The structure is simple and the discharge is smooth.

[0036] In some embodiments, referring to Figure 2 , a first connecting rod 213 is hinged to the edge of the grinding disc 21. A rotating shaft 13 is provided on the frame 10 on the side of the grinding disc 21. The rotating shaft 13 is in transmission connection with the main shaft 11. An eccentric rod 131 is provided at the top of the rotating shaft 13. The eccentric end of the eccentric rod 131 is hinged to the first connecting rod 213.

[0037] The turntable 22 can be directly sleeved on the main shaft 11 and rotate continuously and unidirectionally with the main shaft 11. The grinding disc 21 is also connected to the main shaft 11 in a rotational fit manner, which can improve the coaxiality between the grinding disc 21 and the turntable 22, thereby improving the working stability. On this basis, the main shaft 11 drives the rotating shaft 13 to rotate, and the eccentric rod 131 on the rotating shaft 13 rotates accordingly. Since the distance between the eccentric end of the eccentric rod 131 and the connection point of the grinding disc 21 (and the first connecting rod 213) changes periodically during the rotation process, when the first connecting rod 213 is connected to the eccentric rod 131 and the grinding disc 21, the rotational motion of the rotating shaft 13 can be synchronously converted into the reciprocating swinging of the grinding disc 21. The transmission structure is simple and stable, and two kinds of motion outputs can be realized by using the same power source, thereby improving the motion coordination of the grinding disc 21 and the turntable 22.

[0038] As a specific embodiment of the above separation mechanism, please refer to Figure 2 , Figure 7 and Figure 8The separation mechanism includes a connecting frame 31, a box body 32 and two sets of separation screens 33; the connecting frame 31 is fixedly connected to the frame 10 and is located below the crushing mechanism 20. Two guide rails 311 are spaced apart on the connecting frame 31; the two sides of the box body 32 are respectively slidably connected to the two guide rails 311, the box body 32 is connected to the main shaft 11 and swings back and forth along the guide rails 311 driven by the main shaft 11. The top wall of the box body 32 is provided with a second feeding port 301, and the bottom is provided with a third blanking port 302 and the fourth feeding port 303; two groups of separation screens 33 are distributed in the box body 32 at intervals, and the two groups of separation screens 33 are tilted up and down, and the tilt directions of the two groups of separation screens 33 are opposite; wherein, the adhesion body falls from the second feeding port 301 to the upper separation screen 33, and the adhesion body rolls down based on the tilted separation screen 33, and the rolling direction is perpendicular to the swing direction of the box body 32, and the adhesion body passes through each group of separation screens 33 in turn to form separated loose pulp and clean fruit cores.

[0039] After the fruit pulp is crushed by the crushing mechanism 20, the separated adhesion bodies enter the second feeding port 301 through the second drop port 203, and then fall onto the separation screen 33 on the upper layer. As the box body 32 moves back and forth linearly, the separation screen 33 screens the adhesion bodies. During the screening process, the adhesion bodies roll along the inclined direction of the separation screen 33 and enter the separation screen 33 on the lower layer. After another screening process, the fruit pulp is completely separated from the fruit core. In order to ensure that the adhesion bodies remain attached to the separation screen 33 during the screening process, the inclined direction of the separation screen 33 is set to an angle perpendicular to the movement direction of the box body 32, that is, the separation screen 33 is set to an inclined setting with the front higher and the back lower, while the box body 32 moves back and forth left and right.

[0040] Performing two screenings through two layers of separation screens 33 can improve the screening effect and reduce the amount of pulp adhering to the core. At the same time, the vibration screening method using the inclined separation screen 33 has a larger effective working area, thereby improving the screening efficiency.

[0041] Specifically, as a specific embodiment of the separation screen 33, please refer to Figure 7 and Figure 8, the separation sieve 33 includes a sieve plate 331 and a chassis 332 which are arranged at an upper and lower interval. The sieve plate 331 is used to allow the separated crushed pulp to leak onto the chassis 332 during the rolling of the agglomerates; at the lower end of the sieve plate 331 of the upper separation sieve 33, an arched guide plate 3311 is provided. A first material dropping channel 3301 is formed between the outer arched surface of the arched guide plate 3311 and the two side walls of the box body 32. At the lower end of the chassis 332 of the upper separation sieve 33, an arc plate 3321 which bends downward is provided, and a diversion strip 3322 is provided on the lower end plate surface of the upper chassis 332. A second material dropping channel 3302 is formed between the arc plate 3321 and the inner arched surface of the arched guide plate 3311. The diversion strip 3322 is used to guide the crushed pulp into the second material dropping channel 3302; wherein, the unseparated agglomerates and the separated fruit stones on the upper sieve plate 331 both fall through the first material dropping channel 3301 to the upper end of the lower sieve plate 331, and the crushed pulp on the upper chassis 332 falls through the second material dropping channel 3302 to the upper end of the lower chassis 332; a third material dropping port 302 is provided on the bottom wall of the box body 32 and is located between the lower ends of the lower sieve plate 331 and the chassis 332; a fourth material dropping port 303 is provided on the side wall of the box body 32 and is flush with the lower end of the lower sieve plate 331.

[0042] The separation sieve 33 forms a vibration effect with the linear reciprocating motion of the box body 32. During the vibration process, the crushed pulp gradually falls off from the fruit stones to form crushed pulp which falls from the sieve plate 331 onto the chassis 332. The fruit stones and the uncompletely separated agglomerates staying on the upper sieve plate 331 roll downward along the inclined angle to the arched guide plate 3311, and then are diverted to both sides along the arched guide plate 3311 and enter the first material dropping channel 3301, and then fall to the upper end of the lower sieve plate 331. Then, through further vibration screening by the lower sieve plate 331, the crushed pulp on the upper chassis 332 slides downward along the inclined direction of the chassis 332 during the vibration process and enters the second material dropping channel 3302 under the guidance of the arc plate 3321, and then falls to the upper end of the lower chassis 332. Finally, it slides together with the crushed pulp dropped after further screening by the lower sieve plate 33 to the lower end of the lower chassis 332, and then is discharged from the third material dropping port 302; while the remaining clean fruit stones on the lower sieve plate 331 slide to the bottom end of the sieve plate 331 and are discharged from the fourth material dropping port 303, thus completing the entire pulp separation process.

[0043] Further, as Figure 7As shown, to enhance the screening efficiency of the separation screen 33, the screen plate 331 is provided with multiple ribs 3312 spaced along its inclination. These ribs 3312 extend along the direction of motion of the housing 32, and their protrusions are smaller than the size of clean fruit pits. During the vibrating screening process of the screen plate 331, the fruit pits and unseparated, adhered objects are able to pass over the ribs 3312 and roll downward, while the separated, loose fruit pulp is blocked by the ribs 3312 and can only fall through the holes in the screen plate 331. This prevents the loose fruit pulp from falling along with the fruit pits due to its inability to escape, thereby enhancing the screening efficiency.

[0044] For some possible implementations, see Figure 7 A spray pipe 50 is provided on the side wall of the box body 32, and the spray pipe 50 is used to connect the high-pressure water pipe. The spray pipe 50 extends between the two groups of separation screens 33 and is connected to the bottom wall of the upper separation screen 33. A plurality of nozzles 51 are distributed in an array on the spray pipe 50, and each nozzle 51 is used to uniformly spray high-pressure water toward the separation screen 33 below.

[0045] The adhesion between the pulp and the core that has not been completely separated after screening by the upper separation screen 33 must be relatively large. Therefore, it may not be possible to completely separate these adhered bodies by simply vibrating the separation screen 33. Therefore, a spray pipe 50 is set above the lower separation screen 33, and high-pressure water is sprayed onto the lower separation screen 33 through the nozzle 51, so that the pulp adhered to the core is completely separated under the vibration and high-pressure water flushing, thereby improving the pulp separation effect; moreover, since water is only sprayed on the adhered bodies that cannot be completely separated, the water consumption is lower than that of the conventional method; the loose pulp discharged from the third discharge port 302 is mixed with water, while the loose pulp separated by the first discharge port 202 does not contain water, which can facilitate the post-processing classification of the loose pulp.

[0046] In some embodiments, such as Figure 2 As shown, a second connecting rod 321 is hinged on the outer walls of the two opposite sides of the above-mentioned box body 32, and a rotating wheel 312 is rotatably connected to each of the two guide rails 311. The two rotating wheels 312 are provided with an eccentric shaft 3121, and the eccentric shafts 3121 on the two rotating wheels 312 are respectively hinged to the two second connecting rods 321; the two rotating wheels 312 are both connected to the main shaft 11 in a transmission manner.

[0047] Specifically, the two rotating wheels 312 are connected by a transmission shaft, and a transmission member such as a gear that is in transmission connection with the main shaft 11 is sleeved on the transmission shaft, so that the power of the main shaft 11 is transmitted to the two rotating wheels 312. During the rotation of the two rotating wheels 312, the second connecting rod 321 connected to the respective eccentric shafts 3121 drives the box body 32 to perform a linear reciprocating motion along the guide rail 311. The transmission structure is simple and stable, and there is no need to additionally set a power source to simultaneously satisfy the synchronous actions of the crushing mechanism 20 and the separation mechanism, which not only saves costs but also has high motion synchronization.

[0048] Optionally, please refer to Figure 2 , in this embodiment, the structure of the rotary drive member 40 is that the rotary drive member 40 includes a drive motor 41, a first transmission wheel 42, and a second transmission wheel 43; wherein, the drive motor 41 is fixedly connected to the frame 10, and a drive wheel 411 is sleeved on the output end of the drive motor 41; the first transmission wheel 42 is sleeved on the main shaft 11 and is in transmission connection with the drive wheel 411; the second transmission wheel 43 is sleeved on the main shaft 11 and is in transmission connection with the power input end of the separation mechanism.

[0049] The drive wheel 411, the first transmission wheel 42, and the second transmission wheel 43 can be belt wheels or sprocket wheels. Of course, they can also be gears when the installation layout space is satisfied. The drive motor 41 drives the main shaft 11 to rotate through the transmission connection between the drive wheel 411 and the first transmission wheel 42, such as belt or chain connection. The main shaft 11 directly drives the crushing mechanism 20 connected thereto to operate, while the separation mechanism is in transmission connection through the second transmission wheel 43 (such as a bevel gear) sleeved on the main shaft 11 and the power input end (such as a bevel gear) of the separation mechanism, so as to realize that one drive source simultaneously drives the crushing mechanism 20 and the separation mechanism to act. The transmission structure is flexible and reliable, has a high integration degree, and can improve the operation synchronization of the crushing mechanism 20 and the separation mechanism, thereby improving the stability and efficiency of the pulp separation work.

[0050] The above are only the preferred embodiments of the present invention and are 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.
