Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of filtering equipment, in particular to a white bean grinding sand material pressure filter device. BACKGROUND

[0002] The white bean cooking, sand pressing and water flowing line has six links of feeding, conveying, cooking, grinding, washing and dewatering, wherein the grinding and washing links refer to pressing and grinding the cooked beans into sand liquid slurry (hereinafter referred to as sand material, which is mainly a mixture of soybean milk and soybean residue), and then filtering the sand material to separate the soybean milk and the soybean residue. The pressing and grinding and separation of the soybean milk and the soybean residue are completed by a pressure filter device, which comprises a sand grinder and a vibrating screen. When working, the sand grinder first presses and grinds the cooked beans to break them, forming sand material, which is then filtered by the vibrating screen to separate the soybean milk and the soybean residue.

[0003] As shown in Figure 1 , the vibrating screen is provided with a plurality of vibration motors in the circumferential direction, and the vibration frequencies of the plurality of vibration motors are cooperatively controlled (the plurality of vibration motors are cooperatively controlled by a PLC) to make the material on the screen mesh in the screen cylinder vibrate and also make centrifugal motion, so as to achieve better dispersion and screening effect in the screening process.

[0004] However, as shown in Figure 2 , when the sand material is filtered by the vibrating screen, the soybean residue will gradually accumulate on the surface of the screen mesh. Although the centrifugal force can disperse the soybean residue to the periphery of the screen mesh, thereby maintaining the filtering efficiency of the middle part of the screen mesh to a certain extent, the continuous accumulation of the soybean residue will still cover the middle part of the screen mesh over time, resulting in a gradual decrease in the filtering efficiency of the screen mesh. In the continuous operation of the vibrating screen, the soybean residue accumulated on the surface of the screen mesh needs to be cleaned regularly to ensure that the screen mesh maintains effective filtering performance. However, this regular cleaning requirement undoubtedly brings many inconveniences to the operation, not only increasing the frequency of manual intervention, but also causing frequent interruptions in the production process, greatly reducing the production efficiency and seriously affecting the continuity and smoothness of the entire operation process.

[0044] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0045] In order to further understand the present application, the present application will be described in detail with reference to the drawings.

[0046] In combination with Figures 1-2 In the prior art, the working principle that the vibrating screen 10 makes the material on the first screen in the screen cylinder 11 vibrate while also making centrifugal motion is as follows: when multiple vibrating motors 14 operate synchronously at a specific frequency and phase, the exciting forces generated by the multiple vibrating motors 14 form a vibration field in the screen cylinder 11. This vibration field not only makes the first screen produce high-frequency vibration in the up-down direction, but also produces a “spiral wave” vibration effect in the circumferential direction of the screen cylinder 11 (this spiral wave vibration is similar to the spiral flow of water in a cup when the cup is shaken by hand). The material on the first screen is affected by this spiral wave vibration and produces a spiral trajectory of centrifugal motion along the surface of the first screen. The material moves along the spiral wave direction of the first screen while being thrown up and falling down.

[0047] In combination with Figures 1-15The application relates to a white bean grinding sand filtering device, which comprises a vibrating screen 10, the vibrating screen 10 is provided with screen cylinders 11 which vibrate in a spiral wave mode, so that materials in the screen cylinders 11 can easily move towards the cylinder wall, the outer wall of the screen cylinders 11 is provided with discharge covers 12, two screen cylinders 11 are arranged on the upper and lower sides, the lower screen cylinder 11 is assembled on an assembling cylinder 13, the lower side of the assembling cylinder 13 is supported by a plurality of springs, a plurality of vibrating motors 14 are arranged on the outer side of the assembling cylinder 13 in a circumferential direction, a filtering mechanism 50 is assembled between the two screen cylinders 11, sand 60 formed after beans are crushed by a sand grinder is delivered to the upper side of the filtering mechanism 50, the filtering mechanism 50 separates the sand 60 into bean dregs 61 and bean milk 62, the bean dregs 61 are left on the upper surface of the filtering mechanism 50, and the bean milk leaks out from the lower side; the discharge cover 12 of the upper screen cylinder 11 is used for discharging the bean dregs 61 on the upper surface of the filtering mechanism 50, the door of the discharge cover 12 is in a closed state under the working state of the vibrating screen 10, so that the sand 60 is prevented from being discharged by mistake, and when the filtering mechanism 50 is affected by the excessive bean dregs 61 accumulated on the upper surface, the filtering efficiency is affected, the sand 60 is stopped from being input, the door of the discharge cover 12 is opened after the sand 60 on the upper side of the filtering mechanism 50 is completely separated, and the bean dregs 61 on the upper surface of the filtering mechanism 50 are scraped into the discharge cover 12 and discharged), the discharge cover 12 of the lower screen cylinder 11 is used for discharging the bean milk 62; through the above operation method, the sand 60 is separated into the bean milk 62 and the bean dregs 61, so that the sand 60 can be classified and collected.

[0048] The upper surface of the screen cylinder 11 is provided with a dreg taking mechanism 30, the dreg taking mechanism 30 comprises an assembling cover 33, a rotating disc 31 is rotatably assembled in the inner side of the assembling cover 33, a plurality of dreg taking leaves 32 are arranged on the side surface of the rotating disc 31 in a circumferential direction, when the dreg taking leaves 32 rotate with the rotating disc 31, the dreg taking leaves 32 pass through the upper side of the edge of the filtering mechanism 50, and the dreg taking leaves 32 are unfolded outward when the dreg taking leaves 32 are separated from the inner side of the assembling cover 33, and the sand 60 containing high-concentration bean dregs 61 on the edge of the filtering mechanism 50 is captured through the unfolded dreg taking leaves 32;

[0049] The upper side of the dreg taking mechanism 30 is provided with a squeezing mechanism 20, the squeezing mechanism 20 comprises an inner cylinder 21 which is butted on the upper side of the assembling cover 33, a conveying and extruding assembly is arranged in the inner side of the inner cylinder 21, an outer cylinder 23 is arranged on the outer side of the inner cylinder 21, the movable dreg taking leaves 32 cooperate with the assembling cover 33 to convey the captured sand 60 into the inner cylinder 21, the sand 60 is further squeezed and conveyed by the conveying and extruding assembly, when the dreg taking leaves 32 capture the sand 60, the bean milk 62 in the screen cylinder 11 needs to be prevented from penetrating into the assembling cover 33, so as to avoid entering into the inner cylinder 21 and affecting the squeezing effect of the conveying and extruding assembly on the sand 60 containing high-concentration bean dregs 61;

[0050] One side of the screen cylinder 11 is provided with a driving mechanism 40, which is used for driving the rotating operation of the conveying and extruding assembly and the rotating disc 31.

[0051] Specifically, the sand material 60 in the screen cylinder 11 is subjected to spiral flow under the action of the "spiral wave" vibration field, and the spiral direction is opposite to the rotation direction of the rotating disc 31, so that the expanded residue taking blade 32 can smoothly capture the sand material 60 containing high-concentration soybean residue 61 at the edge of the filtering mechanism 50, and then the residue taking blade 32 continues to rotate with the rotating disc 31 to transport the captured sand material 60 into the inner cylinder 21, so that the sand material 60 is further squeezed by the conveying and squeezing assembly in the inner cylinder 21 to separate the soybean milk 62 and the soybean residue 61, thereby achieving recycling.

[0052] With the discharge of the sand material 60 containing high-concentration soybean residue 61 on the upper side of the filtering mechanism 50, the content of the soybean residue 61 covering the upper surface of the filtering mechanism 50 is reduced, which avoids excessive accumulation of the soybean residue 61 on the upper side of the filtering mechanism 50, thereby reducing the filtering efficiency of the filtering mechanism 50 or even causing the filtering mechanism 50 to be unable to filter. Further, the vibrating screen 10 can also meet the demand for continuous operation.

[0053] In combination Figures 2-12 The assembly cover 33 is fixedly assembled on the outer side surface of the screen cylinder 11, the inner side of the assembly cover 33 is provided with a leaf closing cavity 331, the rotating disc 31 is rotatably assembled in the inner side of the leaf closing cavity 331 through a second rotating shaft 311, the second rotating shaft 311 penetrates through the lower surface of the assembly cover 33, and the leaf closing cavity 331 is communicated to the inner side of the screen cylinder 11, so as to facilitate the condition that the residue taking blade 32 rotates with the rotating disc 31 to pass through the upper side of the edge of the filtering mechanism 50.

[0054] As shown in Figure 10 In order to automatically expand the residue taking blade 32 when passing through the edge of the filtering mechanism 50, and prevent the residue taking blade 32 from colliding with the inlet of the residue taking blade 32 when returning to the leaf closing cavity 331, causing damage to the residue taking blade 32 and the rotating disc 31 being stuck, the present embodiment is characterized in that: the residue taking blade 32 is rotatably assembled on the side of the rotating disc 31 through a third rotating shaft 321, the third rotating shaft 321 is fixedly connected with a limiting rod 322 on the side, one side of the limiting rod 322 is provided with a second tension spring 323, a limiting cavity 312 is formed in the rotating disc 31, the limiting rod 322 is movably arranged in the inner side of the limiting cavity 312, one end of the second tension spring 323 is fixedly connected to the inner wall of the limiting cavity 312, and the limiting rod 322 is pulled by the second tension spring 323 and cooperates with the limiting cavity 312, so that the residue taking blade 32 rotates outward about the third rotating shaft 321 to the maximum angle. By limiting the expansion angle of the residue taking blade 32, the end of the residue taking blade 32 away from the rotating disc 31 can smoothly return to the leaf closing cavity 331, avoiding collision between the residue taking blade 32 and the inlet of the leaf closing cavity 331, causing damage to the residue taking blade 32 and the rotating disc 31 being stuck.

[0055] As shown in Figure 10As shown, when the slag-removing leaf 32 rotates into the inside of the joint-leaf cavity 331 along with the rotation of the rotating disc 31, the far end of the slag-removing leaf 32 slides against the side wall of the joint-leaf cavity 331, which gradually approaches the side surface of the rotating disc 31 along the rotation direction of the rotating disc 31, so as to drive the far end of the slag-removing leaf 32 to rotate around the rotating shaft three 321 until the far end of the slag-removing leaf 32 is attached to the side surface of the rotating disc 31. The curvature of the rotating disc 31 is matched with the arc surface of the slag-removing leaf 32.

[0056] As shown, Figure 10 Specifically, due to the rotation of the rotating disc 31, when the slag-removing leaf 32 moves to the inside of the screen cylinder 11, the slag-removing leaf 32 is unfolded at the inside of the screen cylinder 11 under the pulling action of the pulling spring two 323 due to the absence of the constraint of the side wall of the joint-leaf cavity 331, so as to form a storage space between the slag-removing leaf 32 and the rotating disc 31 for capturing the sand material 60. Since the bean dregs 61 in the sand material 60 are prone to gathering at the edge of the filtering mechanism 50, the sand material 60 at the edge of the filtering mechanism 50 has the highest concentration of the bean dregs 61, and the slag-removing leaf 32 captures the sand material 60 containing the high-concentration bean dregs 61, which is beneficial to reducing the overall content of the bean dregs 61 in the screen cylinder 11, preventing the excessive accumulation of the bean dregs 61 on the filtering mechanism 50, avoiding the influence on the filtering efficiency of the filtering mechanism 50, and enabling the vibrating screen 10 to work for a long time.

[0057] As shown, Figure 10 Further, after the slag-removing leaf 32 rotates into the inside of the rotating shaft two 311, the storage space between the slag-removing leaf 32 and the rotating disc 31 is closed by the inner wall of the joint-leaf cavity 331 to form a space enclosed on all sides. With the continuous movement of the slag-removing leaf 32, the volume of the enclosed space gradually decreases, so that the sand material 60 stored in the enclosed space is squeezed into the inner cylinder 21. Since the internal pressure of the enclosed space increases in the process of the decrease of the volume, the soybean milk 62 in the screen cylinder 11 is not easy to penetrate into the slag-removing leaf 32 through the operation channel of the joint-leaf cavity 331, i.e. Figure 10 the half-moon cavity formed between the rotating disc 31 and the assembly cover 33) to avoid affecting the squeezing function of the slag-removing leaf 32;

[0058] As shown, Figure 11Further, as the volume of the closed space gradually decreases, the shrinking space has a squeezing effect on the sand 60 inside. By opening a filter groove 332 on the inner wall of the leaf cavity 331 and assembling a filter plate 333 in the filter groove 332, the filter plate 333 acts as a side wall in the original leaf cavity 331. The filter plate 333 is rigid, and when the sand 60 in the closed space is gradually squeezed, a preliminary filtration is formed through the filter plate 333. The squeezed soy milk 62 is collected in the filter groove 332 and is discharged through the discharge pipe 334 connected to the bottom of the filter groove 332 for collection. In this way, when the separation effect of the sand 60 in the closed space is not high, the filter plate 333 assembled by the cover 33 itself can complete the separation effect of the sand 60 transported inside, without the need to assemble the squeezing mechanism 20, making the device more simple and efficient as a whole.

[0059] It should be noted that the position of the filter groove 332 should avoid indirect communication with the cavity in the screen cylinder 11 through the closed space, so that a large amount of soy milk 62 in the screen cylinder 11 is poured into the filter groove 332, and further poured back into multiple adjacent closed spaces and the inner cylinder 21.

[0060] It should be noted that when the filter plate 333 is connected to the side wall of the leaf cavity 331, there is a joint that can easily affect the sliding connection structure of the one end of the residue removing leaf 32 and the side wall of the leaf cavity 331. By rounding the one end of the residue removing leaf 32, the one end of the residue removing leaf 32 can smoothly slide through the joint position.

[0061] In combination Figure 12 , the residue removing leaf 32 is provided with an upward inclined surface on the side of the rotating disc 31, so that when the residue removing leaf 32 is combined to the surface of the rotating disc 31, the sand 60 therebetween can be easily squeezed out.

[0062] In combination Figures 3-8 , the conveying and squeezing assembly includes a rotating cylinder 25 rotatably assembled on the inside of the inner cylinder 21. The rotating cylinder 25 is provided with helical blades 26 on the side surface. The rotating shaft one 24 is coaxially fixedly connected to the upper side of the rotating cylinder 25 and penetrates the upper surface of the inner cylinder 21. A plurality of screen holes 211 are circumferentially formed on the side surface of the inner cylinder 21. The inner cylinder 21 is communicated with the upper discharge cover 12 through the residue discharge hopper 22.

[0063] The outer cylinder 23 is connected with a bottom disc 231 on the lower side. The surface of the bottom disc 231 is provided with a circular groove for assembling the inner cylinder 21. The circular groove is communicated with the leaf cavity 331. The lower surface of the bottom disc 231 is provided with a soy milk leakage pipe 232 communicated with the lower discharge cover 12.

[0064] Specifically, the distance between the adjacent blades of the helical blades 26 gradually decreases from bottom to top.

[0065] After the slag removing blade 32 squeezes the sand material 60 in the hinge cavity 331 to the inner side of the inner cylinder 21, the spiral blade 26 rotates with the rotating cylinder 25 to transport the sand material 60 upward. During the transportation process, the spiral blade 26 will produce an extrusion effect on the sand material 60, causing the soy milk 62 contained in the sand material 60 to leak out from the sieve hole 211 and flow into the discharge cover 12 below for collecting the soy milk 62 through the leakage pipe 232, while the bean dregs 61 slowly formed as the spiral blade 26 rises are discharged from the slag discharge hopper 22 into the discharge cover 12 above for collecting the bean dregs 61, thereby realizing the further separation of the sand material 60 in the inner cylinder 21 into bean dregs 61 and soy milk 62 for classified recycling.

[0066] Combine Figure 4 、 Figure 8 The driving mechanism 40 includes a driving motor fixedly assembled on the upper surface of the inner cylinder 21, and the output end of the driving motor is fixedly connected to the rotating shaft 24; the driving mechanism 40 also includes a pulley 2 44 fixedly connected to the surface of the rotating shaft 24, and a connecting rod 42 rotatably assembled on the outer surface of the outer cylinder 23, and a pulley 1 41 and a pulley 3 43 are respectively provided at the upper and lower ends of the connecting rod 42. The pulley 1 41 is connected to the pulley 2 44 through a belt, and the pulley 3 43 is connected to the pulley 4 fixedly connected to the lower end of the rotating shaft 2 311 through a belt. While the driving motor controls the rotation of the rotating shaft 24, it also drives the rotating shaft 2 311 to rotate through the transmission relationship, so that the rotation of the rotating drum 25 and the turntable 31 are controlled at the same time, so as to simplify the device.

[0067] Combine Figures 7-15 The filtering mechanism 50 includes a screen 51 and an outer hoop 52 fixedly connected to the edge of the screen 51. The upper surface of the outer hoop 52 has a downwardly concave groove, and the groove wall of the outer hoop 52 is provided with an insertion port 521. The insertion port 521 cooperates with the turntable 31 to allow the slag leaf 32 to enter the groove of the outer hoop 52.

[0068] The outer hoop 52 is used to make it easier for the dregs 61 on the edge of the second screen 51 to concentrate at the bottom of the groove of the outer hoop 52, thereby further increasing the concentration of the dregs 61 when the dregs leaf 32 captures the sand 60, thereby improving the capture efficiency.

[0069] Combine Figures 14-15 The second screen 51 is arranged in an "umbrella" shape, a support seat 53 is provided in the middle of the second screen 51, and is supported by a telescopic rod 54 fixedly assembled on the vibrating screen 10, so that the second screen 51 bulges upward.

[0070] The upper surface of the "umbrella-shaped" screen 2 51 is tilted downward, which on the one hand facilitates the bean dregs 61 to slide to the edge; on the other hand, when the content of bean dregs 61 in the screen cylinder 11 is fixed, the coverage area of ​​the bean dregs 61 on the surface of the "umbrella-shaped" screen 2 51 will be smaller than that of the flat screen 2 51, thereby improving the filtration efficiency of the screen 2 51.

[0071] The above merely illustrates the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacements or changes within the technical scope disclosed by the present application and according to the technical solutions and the inventive concept of the present application, which should be covered within the protection scope of the present application.
