Description

Technical Field

[0001] The utility model relates to the field of food processing, in particular to a konjac powder grinding device. Background Art

[0002] In the process of konjac flour processing, the dried konjac is crushed and ground into flour. The existing grinding device includes a base, a grinding groove is provided on the base, a top cover is provided at one end of the grinding groove away from the base, a grinding mechanism is provided in the grinding groove, a motor is provided in the base to provide power for the grinding mechanism, a filter plate is provided on the contact surface between the grinding groove and the base, an inlet is provided on the top cover, a collecting groove is provided in the base, a conveyor belt is provided under the collecting groove, and the conveyor belt transmits the material in the collecting groove to the discharge port on the side of the base. The device is provided with grinding knives of different specifications on the grinding wheel, the grinding disc and the inner wall of the grinding groove, which can complete the cutting, crushing and grinding processes one by one; the above device is provided with a conveyor belt in the base, which can continuously transport the ground konjac flour outward.

[0003] The existing grinding device has the following problems: the fine powder that has been ground to a standard size enters the collection tank through the filter plate, and the filter plate needs to be removed to grind the unqualified particles on the filter plate again. When the filter plate is removed, the equipment needs to be shut down and cannot continue to work.

[0004] Based on the above situation, a konjac flour grinding device is urgently needed to solve the problem that the equipment cannot work continuously. Utility Model Content

[0005] The purpose of the utility model is to: for the existing grinding device, the fine powder that reaches the standard size enters the collecting tank through the filter plate, and the filter plate needs to be taken out to grind the unqualified particles on the filter plate again. When the filter plate is taken out, the equipment needs to be shut down and cannot continue to work, thereby solving the problem that the equipment cannot continue to work.

[0006] The technical solution of the utility model is as follows:

[0007] A konjac flour grinding device, characterized in that it comprises:

[0008] A grinding mechanism, used for grinding konjac to form fine powder;

[0009] A screening mechanism, cooperating with the grinding mechanism and used to screen out fine powder with a particle size larger than a preset value;

[0010] The reflux mechanism cooperates with the screening mechanism and is used to return the refined powder to the grinding mechanism.

[0011] In the existing grinding device, the fine powder that has been ground to a standard size enters the collecting tank through the filter plate, and the filter plate needs to be removed to grind unqualified particles on the filter plate again. The equipment needs to be shut down when the filter plate is taken out, and cannot work continuously. In the present solution, the unqualified particles screened out by the screening mechanism are returned to the grinding mechanism for re-grinding through the reflux mechanism, thereby avoiding the step of removing the filter screen in the traditional solution. The screening mechanism can continuously screen the fine powder particles without shutting down, thereby solving the problem that the equipment cannot work continuously.

[0012] Furthermore, the present solution does not limit the specific structure of the screening mechanism. One feasible solution is: the screening mechanism includes a pyramid structure and a plurality of screens are installed on the pyramid structure. When this solution is adopted, the screen can screen out unqualified fine powder particles with a particle size greater than a preset value. Under the action of the pyramid structure, the unqualified fine powder particles naturally gather at the top of the pyramid structure under the action of gravity, so as to facilitate centralized collection by the reflux mechanism.

[0013] Furthermore, in order to improve the screening efficiency of fine powder particles, one feasible solution is: a polarization motor is installed on the screening mechanism. When this solution is adopted, the screening mechanism is driven to vibrate by the polarization motor, thereby improving the screening efficiency of fine powder particles.

[0014] Furthermore, in order to facilitate replacement and cleaning of the screen, one feasible solution is: fasteners are detachably installed between the screen and the pyramid structure. When this solution is adopted, the screen can be easily and quickly removed by removing the fasteners, so as to facilitate replacement and cleaning of the screen.

[0015] Furthermore, the present solution does not limit the specific structure of the reflux mechanism. One feasible solution is: the reflux mechanism includes a reflux pipe cooperating with the screening mechanism, and the reflux pipe is connected to a fan. When this solution is adopted, a negative pressure is formed at one end of the reflux pipe by the fan, thereby sucking unqualified fine powder particles into the reflux pipe and transporting them to the grinding mechanism.

[0016] Furthermore, in order to reduce the influence of the return pipe on the screening mechanism, one feasible solution is: a lifting rod is connected to the end of the return pipe close to the screening mechanism. When this solution is adopted, the fan works intermittently. When the fan stops working, the lifting rod drives the return pipe away from the screening mechanism. When the screening process is sufficient, the lifting rod drives the return pipe close to the screening mechanism and starts the fan.

[0017] Furthermore, the present solution does not limit the specific structure of the grinding mechanism. One feasible solution is: the grinding mechanism includes at least two grinding rollers that cooperate with each other, one of which is connected to a grinding motor. When this solution is adopted, the grinding motor drives the grinding roller to rotate to achieve grinding.

[0018] Compared with the existing technology, the beneficial effects of the utility model are:

[0019] 1. The unqualified particles screened out by the screening mechanism are returned to the grinding mechanism for re-grinding by the reflux mechanism, thereby avoiding the step of removing the filter screen in the traditional solution. The screening mechanism can continuously screen the fine powder particles without stopping the machine, thus solving the problem that the equipment cannot work continuously;

[0020] Second, since the screening mechanism includes a pyramid structure and a plurality of screens are installed on the pyramid structure, unqualified fine powder particles with a particle size greater than a preset value can be screened out through the screen. Under the action of the pyramid structure, the unqualified fine powder particles naturally gather at the top of the pyramid structure under the action of gravity, so as to be collected centrally by the reflux mechanism;

[0021] Third, since fasteners are detachably installed between the screen and the pyramid structure, the screen can be easily and quickly removed by removing the fasteners, so as to facilitate replacement and cleaning of the screen. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0034] Example:

[0035] Please refer to Figure 1 , a konjac flour grinding device, characterized in that it comprises:

[0036] A grinding mechanism 1 is used for grinding konjac to form fine powder;

[0037] The screening mechanism 2 cooperates with the grinding mechanism 1 and is used to screen out the fine powder with a particle size larger than a preset value;

[0038] The reflux mechanism 3 cooperates with the screening mechanism 2 and is used to return the refined powder to the grinding mechanism 1 .

[0039] In the existing grinding device, the fine powder that has been ground to a standard size enters the collecting tank through the filter plate, and the filter plate needs to be removed to grind unqualified particles on the filter plate again. The equipment needs to be shut down when the filter plate is taken out and cannot work continuously. In this solution, the unqualified particles screened out by the screening mechanism 2 are returned to the grinding mechanism 1 for re-grinding through the reflux mechanism 3, thereby avoiding the step of removing the filter screen in the traditional solution. The screening mechanism 2 can continuously screen the fine powder particles without shutting down, thereby solving the problem that the equipment cannot work continuously.

[0040] Reference Figure 3The present solution does not limit the specific structure of the screening mechanism 2. One feasible solution is that the screening mechanism 2 includes a pyramid structure 21 and a plurality of screens 22 are installed on the pyramid structure 21. When this solution is adopted, the screens 22 can screen out unqualified fine powder particles with a particle size greater than a preset value. Under the action of the pyramid structure 21, the unqualified fine powder particles naturally gather at the top of the pyramid structure 21 under the action of gravity, so as to be collected centrally by the reflux mechanism 3.

[0041] In order to improve the screening efficiency of fine powder particles, one feasible solution is: a polarization motor 23 is installed on the screening mechanism 2. When this solution is adopted, the polarization motor 23 drives the screening mechanism 2 to vibrate, thereby improving the screening efficiency of fine powder particles.

[0042] Reference Figure 3 and Figure 4 In order to facilitate the replacement and cleaning of the screen 22, one feasible solution is that a fastener 24 is detachably installed between the screen 22 and the pyramid structure 21. Specifically, in this embodiment, the fastener 24 is a bolt. When this solution is adopted, the screen 22 can be easily and quickly disassembled by removing the fastener 24, so as to facilitate the replacement and cleaning of the screen 22.

[0043] Reference Figure 2 This solution does not limit the specific structure of the reflux mechanism 3. One feasible solution is: the reflux mechanism 3 includes a reflux pipe 31 that cooperates with the screening mechanism 2, and the reflux pipe 31 is connected to a fan 32. When this solution is adopted, a negative pressure is formed at one end of the reflux pipe 31 by the fan 32, so that unqualified fine powder particles are sucked into the reflux pipe 31 and transported to the grinding mechanism 1.

[0044] Reference Figure 5 In order to reduce the influence of the return pipe 31 on the screening mechanism 2, one feasible solution is: a lifting rod 33 is connected to one end of the return pipe 31 close to the screening mechanism 2. When this solution is adopted, the fan 32 works intermittently. When the fan 32 stops working, the lifting rod 33 drives the return pipe 31 away from the screening mechanism 2. When the screening process is sufficiently carried out, the lifting rod 33 drives the return pipe 31 close to the screening mechanism 2 and starts the fan 32.

[0045] This solution does not limit the specific structure of the grinding mechanism 1. One feasible solution is: the grinding mechanism 1 includes at least two grinding rollers 11 that cooperate with each other, and one of the grinding rollers 11 is connected to a grinding motor 12. When this solution is adopted, the grinding motor 12 drives the grinding roller 11 to rotate to achieve grinding.

[0046] The working principle of this embodiment:

[0047] The konjac to be ground is poured into the feed hopper 13, and the grinding motor 12 drives the grinding roller 11 to rotate to grind the konjac. The fine powder formed after grinding naturally falls into the screening mechanism 2, and the polarization motor 23 drives the screening mechanism 2 to vibrate to speed up the screening efficiency. The fine powder particles with a particle size smaller than the preset size can pass through the screen 22, and the fine powder particles with a particle size larger than the preset size will remain on the top of the pyramid structure 21. When the screening process is carried out for a specified time, the lifting rod 33 drives the reflux pipe 31 close to the pyramid structure 21, and the fan 32 is started to suck the fine powder particles into the reflux pipe 31 and transport them to the feed hopper 13 for grinding again. After the reflux process is carried out for a specified time, the fan 32 stops working, and the lifting rod 33 drives the reflux pipe 31 away from the pyramid structure 21, and so on.

[0048] In order to solve the problem that the equipment cannot work continuously, in this solution, the unqualified particles screened out by the screening mechanism 2 are returned to the grinding mechanism 1 for re-grinding through the reflux mechanism 3, thereby avoiding the step of removing the filter in the traditional solution. The screening mechanism 2 can continuously screen the fine powder particles without stopping, thus solving the problem that the equipment cannot work continuously.

[0049] In order to facilitate the reflux mechanism 3 to collect unqualified fine powder particles in a centralized manner, in the present embodiment, since the screening mechanism 2 includes a pyramid structure 21 and a plurality of screens 22 are installed on the pyramid structure 21, the unqualified fine powder particles with a particle size greater than a preset value can be screened out through the screen 22. Under the action of the pyramid structure 21, the unqualified fine powder particles naturally gather at the top of the pyramid structure 21 under the action of gravity, so as to facilitate the reflux mechanism 3 to collect them in a centralized manner.

[0050] In order to facilitate replacement and cleaning of the screen 22, in this solution, since fasteners 24 are detachably installed between the screen 22 and the pyramid structure 21, the screen 22 can be easily and quickly removed by removing the fasteners 24, so as to facilitate replacement and cleaning of the screen 22.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
