Description

Technical Field

[0001] The invention relates to the technical field of vibrating screens, in particular to an automatic rejection vibrating screen. Background Art

[0002] In the production process of cakes, there are different requirements for the particle size of raw materials (such as flour, white sugar, starch, auxiliary materials, etc.) to suit the production of different types of cakes. For example, white sugar can be divided into many grades according to the particle size, such as coarse sugar, general sugar, fine sugar, extra fine sugar, and caster sugar. In baking operations, when making cakes or biscuits, fine sugar is usually used, which is easier to integrate into the dough or batter; when beating egg whites, using coarser sugar will be more conducive to the beating operation, but the foam will be rougher, and using finer sugar will be slower, and the corresponding foam structure will be smoother; after sifting the flour, the fineness of the flour can be guaranteed to be uniform, which is conducive to mixing with eggs, butter and other raw materials, and the finished product has a more delicate and soft taste; therefore, in the actual production process of cakes, sifting the raw materials is an indispensable process.

[0003] The rotary vibrating screen is one of the commonly used equipment for screening cake raw materials. It uses a vertical motor as the excitation source. Eccentric weights are installed at the upper and lower ends of the motor to convert the motor's rotational motion into horizontal, vertical and inclined three-dimensional motion, and then transmit this motion to the screen surface, so that the material makes an outward expansion involute motion on the screen surface. Therefore, this series of vibrating screens are called rotary vibrating screens.

[0004] In the cake production process, different raw materials have different particle size screening requirements. This means that when screening different raw materials, if the same machine is used, the screen needs to be replaced, which requires stopping the machine and disassembling it. The overall operating efficiency is low, affecting the cake processing efficiency. After screening, some filter holes of the screen are blocked, and the machine needs to be disassembled for cleaning, which further increases the workload. Based on this, an automatic rejection vibrating screen is provided. Summary of the invention

The following is an explanation of its embodiments based on the overall structure of the present invention.

[0023] See also Figures 1 to 10 In the embodiment of the present invention, the automatic rejection vibrating screen includes a vibration component 1, a screening component 2 and a connecting pipe 4. The screening component 2 is provided with multiple groups in the vertical direction. The multiple groups of screening components 2 are connected and conducted through the connecting pipe 4 and the bottom connecting pipe 4 is fixedly connected to the vibration component 1. The vibration component 1 is used to provide a vibration screening force for the screening component 2. The screening component 2 includes a screening circular box 201, a C-shaped fan-shaped seat 202, and a through hole 203; there are two C-shaped partition plates 205, and the two C-shaped partition plates 205 and the C-shaped fan-shaped seat 202 are evenly distributed along the circumference and fixed to the inner side of the screening circular box 201 and are fixedly connected to the upper and lower ends and the side of the screening circular box 201; the through hole 203 is opened in the middle of the C-shaped fan-shaped seat 202 and completely penetrates the C-shaped fan-shaped seat 202 and the upper and lower ends of the screening circular box 201. The cleaning component 3 fixed at the upper and lower ends of the screening circular box 201 is aligned and conducted.

[0024] The screening assembly 2 also includes a discharge port 204, a C-shaped partition plate 205, a rotating disk 206, a T-shaped through hole 207, a screen 208, a discharge notch 210, a guide port 211, and a drive motor 212. The discharge port 204 is opened on one side of the through hole 203 and passes through the C-shaped sector seat 202 and the screening round box 201 to the outside of the screening round box 201. The guide port 211 is fixed to the outside of the screening round box 201 and is aligned with the discharge port 204. The rotating disk 206 is rotatably connected to the C-shaped sector seat 202. , between the two C-shaped partition plates 205, the driving motor 212 is installed and fixed at the top center of the screening circular box 201, and the output shaft of the driving motor 212 passes through the screening circular box 201 and is fixedly connected to the center of the rotating disk 206; there are four T-shaped through holes 207, and the four T-shaped through holes 207 are evenly distributed along the circumference and pass through the upper and lower ends of the rotating disk 206, the screen 208 is installed on the inner side of the T-shaped through hole 207, and the discharge notch 210 is opened on one side of the inner wall of the T-shaped through hole 207 and passes through the outer side of the rotating disk 206.

[0025] The screen 208 aligned with the through hole 203 is used to screen the material, and the channel composed of the discharge gap 210, the discharge port 204, and the guide port 211 is used to discharge the intercepted material. The rotating disk 206 is driven by the driving motor 212 to rotate to achieve the switching of the alignment state of the four screens 208 and the through hole 203, so as to realize screening operations with different particle sizes.

[0026] The vibration assembly 1 includes a base 101, a vibration spring 102, a vibration seat 103, and a vibration motor 104; a plurality of vibration springs 102 are provided, and the plurality of vibration springs 102 are evenly distributed along the circumference and are located between the top of the base 101 and the bottom of the vibration seat 103, and the upper and lower ends of the vibration spring 102 are fixedly connected to the top of the base 101 and the bottom of the vibration seat 103, respectively.

[0027] The vibration motor 104 is installed at the bottom center of the vibration base 103, and the connecting pipe 4 distributed at the bottom is fixed to the top of the vibration base 103, and a bottom discharge port 5 connected to the connecting pipe 4 is also fixed on one side of the bottom connecting pipe 4, and the protruding end of the bottom discharge port 5 is inclined downward; a slope guide plate 6 is installed inside the bottom connecting pipe 4, and the lower end of the slope guide plate 6 is flush with the entrance of the bottom discharge port 5.

[0028] One of the screens 208 in the non-topmost screening assembly 2 is replaced by a planar sealing piece, which is rotated to align with the through hole 203 to achieve the final discharge of the screened material.

[0029] In this embodiment, it should be additionally explained that the apertures of the four screens 208 in the single screening assembly 2 can be selected according to the screening requirements of different materials.

[0030] When screening the raw materials, the number of screening components 2 to be used can be determined according to the number of times the raw materials need to be graded: for example, when one screening is required, only the top screening component 2 is needed, and at this time, the planar sealing pieces on the second group of screening components 2 are adjusted to be aligned with the through holes 203; when a second screening is required, the planar sealing pieces on the third group of screening components 2 are adjusted to be aligned with the through holes 203, and so on and so forth to achieve different numbers of screening operations. It should be noted that when all the screening components 2 are used, the screened materials are finally discharged through the bottom discharge port 5.

[0031] In addition, the screen 208 to be used can be determined based on the particle size of each screening level. At this time, the rotating disk 206 can be driven by the driving motor 212 to rotate, so that the screen 208 to be used can be rotated to be aligned with the through hole 203 (it should be noted that the position of the planar sealing piece is also driven by the driving motor 212. The driving motor 212 can be controlled by an external controller so that the single driving rotation angle of the rotating disk 206 is ninety degrees, thereby realizing convenient switching of the screen 208).

[0032] When the adjustment and setting of the screen 208 and the flat sealing piece are completed, the vibration motor 104 can be started. The operation of the vibration motor 104 drives the vibration base 103 to vibrate, and the vibration base 103 drives the multiple groups of screening components 2 to vibrate. At the same time, the raw materials to be screened are introduced into the uppermost connecting pipe 4, and the raw materials will fall downward along the channel composed of the connecting pipe 4 and the through hole 203. In this process, they can be screened in turn by the multiple screens 208 distributed above and below, and finally retained by the flat sealing piece. The materials of each level retained by the screen 208 and the flat sealing piece will be discharged along the channel composed of the discharge notch 210, the discharge port 204, and the guide port 211 on each group of screening components 2. The guide port 211 can be connected to each collecting device through an external pipeline.

[0033] Through the coordination of the above multiple parts, screening operations of different particle sizes and different grading numbers of different raw materials can be realized, and the convenient switching of the screen 208 can be realized by driving the rotating disk 206 by the driving motor 212. Compared with the traditional operation mode that requires disassembly and replacement of the screen, it is not only more efficient and convenient, but also can effectively reduce the workload of the staff.

[0034] Please refer to Figures 1 to 10The bottom and side of the screening round box 201 are also provided with a cleaning assembly 3, which is used to perform a back-spray cleaning operation on the non-operating screen 208 that has been switched down; the cleaning assembly 3 includes an air inlet pipe 301, an annular nozzle 302, a rotating air nozzle 303, and a suction pipe 304. The air inlet pipe 301 runs from the bottom of the screening round box 201 to the inside of the screening round box 201, and the top of the air inlet pipe 301 is fixedly connected and communicated with the annular nozzle 302 through a branch pipe. There are multiple rotating air nozzles 303, and multiple rotating air nozzles 303 are evenly distributed along the circumferential direction and installed on the upper surface of the annular nozzle 302, and multiple rotating air nozzles 303 are distributed directly below the idle screen 208. The suction pipe 304 runs from one side of the screening round box 201 to the inside of the screening round box 201 and is distributed on one side of the rotating disk 206.

[0035] The air inlet pipe 301 and the suction pipe 304 are connected to an external air pump and a dust collecting device respectively. The air pump delivers high-pressure air to the rotating air nozzle 303 to rotate the rotating air nozzle 303 and spray the screen 208, so as to realize the reverse blowing cleaning of the screen 208. The dust collecting device is operated to collect the cleaned material residues.

[0036] There are three groups of cleaning components 3, which are respectively distributed between the two C-shaped partition plates 205 and between the C-shaped partition plate 205 and the C-shaped fan-shaped seat 202, and the centers of the three air inlet pipes 301 in the three groups of cleaning components 3 are respectively aligned with the centers of the three idle screens 208.

[0037] In this embodiment, when the screen 208 is switched, the previously used screen 208 will be rotated to the middle position between the two C-shaped partition plates 205 or the C-shaped partition plate 205 and the C-shaped fan-shaped seat 202. At this time, the screen 208 is in an idle state, and there may be some residual raw materials on the screen 208. At this time, the screen 208 can be cleaned, and the operation steps are as follows: First, the output end of the external air pump is connected to the air inlet pipe 301 through a soft air pipe, and the suction port of the dust suction device is connected to the suction pipe 304 through a bellows (it should be noted that the pipe 301 and the suction pipe 304 correspond to the position of the screen 208 to be cleaned), and then the external air pump and the dust suction device are started synchronously. The external air pump delivers high-pressure air to the rotating air nozzle 303, so that the rotating air nozzle 303 rotates and blows the screen 208 at the same time, so that the omnidirectional blowing operation on the screen 208 can be realized, so that the residual raw materials stuck in the sieve holes of the screen 208 can be blown away, and the operation of the dust suction device can suck away the air mixed with the raw materials, and then the residual raw materials can be cleaned and collected.

[0038] It should be supplemented that: there is a gap space between the outer side of the corresponding part of the rotating disk 206 and the idle screen 208 and the inner wall of the screening box 201, and the nozzle position of the suction pipe 304 is just in this gap space. During the process of spraying the screen 208, some raw materials are shaken off and fall to the area below the rotating disk 206. It is not convenient for this part of the raw materials to pass through the screen 208 to the top again. Therefore, by setting the suction pipe 304 at a position aligned with the horizontal height of the rotating disk 206, the suction pipe 304 can perform suction operations on the space above and below the rotating disk 206 during suction, so that the residual raw materials can be fully collected.

[0039] Please refer to Figures 5 to 8 The T-shaped through hole 207 is equipped with an annular pressing plate 209 for pressing the edge of the screen 208, and the bottom of the large-diameter notch on the upper part of the T-shaped through hole 207 is formed with an annular groove for the annular side of the annular pressing plate 209 with a "J"-shaped cross section to be installed and embedded.

[0040] The upper surface of the annular pressure plate 209, the upper surface of the screen 208, the inner wall bottom surface of the discharge notch 210, and the inner wall bottom surface of the discharge port 204 are in a horizontal and flush state. When a screen 208 is rotated to be aligned with the through hole 203, the screen 208 and its corresponding annular pressure plate 209 are flush with the lower bottom surface of the receiving end of the discharge port 204.

[0041] In this embodiment: this structure can ensure smooth discharge of raw materials, the annular pressure plate 209 is fixed to the bottom of the inner wall of the annular groove by screws, and the detachable structure of the annular pressure plate 209 can facilitate the replacement and disassembly of the screen 208.

[0042] Please refer to Figures 4 to 10 An annular groove for the rotating disk 206 to rotate is formed in the middle of the C-shaped sector seat 202 and the C-shaped partition plate 205, and a sealing member is provided at the position where the C-shaped sector seat 202 and the C-shaped partition plate 205 contact the rotating disk 206.

[0043] In this embodiment: this structure ensures the smooth rotation of the rotating disk 206. At the same time, the areas where the four screens 208 are located can be independently sealed through the seal, which not only ensures the sealing of the material screening area, but also ensures that the cleaning of the screen 208 will not affect other screens 208.

[0044] Please refer to Figures 1 to 5 An inspection port is provided on the top of the screening circular box 201 away from the through hole 203, and an inspection door 213 is hingedly connected to the inspection port of the screening circular box 201, and a screen 208 away from the through hole 203 is located directly below the inspection port.

[0045] The multiple groups of screening components 2 distributed vertically are distributed in a deflected and dislocated state along the circumferential direction with the connecting pipe 4 as the center, the center line of the connecting pipe 4 coincides with the center line of the base 101 and the vibration seat 103, and the distribution diameter of the multiple vibration springs 102 is greater than the outer diameter of the circumferential distribution track of the multiple screening round boxes 201. The height of the connecting pipe 4 between two adjacent screening round boxes 201 is greater than the turning height of the inspection door 213.

[0046] In this embodiment, the screen 208 at the inspection port can be conveniently replaced by opening the inspection door 213 without disassembling the entire device. The center line of the connecting pipe 4 coincides with the center line of the base 101 and the vibration seat 103, so that the vibration of the device is centered on the connecting pipe 4 and the through hole 203, thereby ensuring the stable operation of the screening operation.

[0047] In addition, through the structural setting of the vertically distributed multiple groups of screening components 2 being distributed in a deflected and dislocated state along the circumferential direction with the connecting pipe 4 as the center, and the structural setting of the distribution diameter of the multiple vibration springs 102 being larger than the outer diameter of the circumferential distribution trajectory of the multiple screening circular boxes 201, the weight of the entire equipment is kept balanced, thereby ensuring the smooth vibration operation. At the same time, the material guide ports 211 on each group of screening components 2 can be staggered in sequence to avoid mutual interference.

[0048] What has been described above are only preferred specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, which should be covered by the protection scope of the present invention.
