[0003] In the production of fruit vinegar, the prior art generally pours all the fruit vinegar and its raw materials into a filter frame, and then filters the fruit vinegar liquid out through the filter holes, and the raw materials remain in the filter frame. However, this filtering method has the following technical defects:

[0004] 1. Since the fruit vinegar and its raw materials are directly poured into the filter frame, the filter holes are easily blocked by solid raw materials, which reduces the filtration speed and the entire filtration process takes a long time;

[0005] 2. A portion of the fruit vinegar liquid attached to the raw materials cannot completely pass through the filter holes, resulting in a high waste rate;

[0006] 3. After filtering, you need to take out the filter frame to clean the raw materials, which is time-consuming and laborious;

[0007] 4. The equipment production process has poor continuity and low degree of automation.

[0008] Therefore, a filtering device for fruit vinegar production with high production efficiency, convenient residue cleaning, sufficient filtration and low waste rate is needed to solve the above problems. Summary of the invention

The connecting shaft can fix and drive the filter barrel, and the reciprocating motor can provide reciprocating rotation motion to drive the screen frame to perform reciprocating rotation motion. This mode of motion has a dual effect in the filtration process: on the one hand, it can effectively throw out the liquid attached to the solid residue through centrifugal force, thereby improving the filtration efficiency; on the other hand, when pouring out the solid residue, the inertia of the reciprocating rotation is utilized to help completely separate the solid residue from the inner wall of the screen frame, prevent the residue from adhering, and ensure that the solid residue can be completely discharged from the screen frame.

[0017] After adopting the above structure, the beneficial effects of the present invention are as follows:

[0018] 1. By controlling the forward and reverse airflows of the air pump, the lifting and lowering movements of the L-shaped connecting pipe and the installation box are realized, and the filtering process is optimized. When the installation box is lowered, in the filtering stage, by introducing gas into the screen frame, the filtering efficiency is effectively improved, making the extraction of fruit vinegar more rapid and thorough. In the residue discharge stage, by blowing air into the filter barrel, the efficiency of residue discharge is effectively improved. On the contrary, when the installation box rises and engages with the touch switch, the filter barrel is triggered to flip. At this time, the rotating disk and the receiving disk rotate in coordination, and the receiving position is cleverly changed, realizing the classified collection of fruit vinegar and solid residues.

[0019] 2. The reciprocating motor can provide reciprocating rotational motion to drive the screen frame to perform reciprocating rotational motion. This motion mode has a dual effect in the filtration process: on the one hand, the liquid attached to the solid residue is thrown out by centrifugal force to improve the filtration efficiency; on the other hand, when pouring out the solid residue, the inertia of the reciprocating rotation is used to completely separate the solid residue from the inner wall of the screen frame to prevent the residue from adhering, ensuring that the solid residue can be completely discharged from the screen frame, thereby improving the continuous operation capacity of the production line;

[0020] 3. By designing a method of discharging part of the airflow from the external air intake, it effectively avoids the material inside the receiving tray from being thrown out due to the rotating disc rotating too fast. It also prevents the receiving tray from rubbing and sliding with the rotating disc due to rotating too fast, ensuring the accuracy of the receiving tray's rotation angle and the accuracy of the material discharge position;

[0021] 4. The operation logic of this device is simple and convenient. The filtering and residue discharge operations can be completed by controlling the forward activation and reverse activation of the air pump. This operation method reduces the complexity of manual operation and makes the whole process more convenient and intuitive. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] A receiving tray 28 is magnetically provided inside the rotating disk 30, a partition 36 is fixedly provided inside the receiving tray 28, a handle 34 is fixedly provided on the upper side of the partition 36, a touch switch 37 is fixedly provided on the top inner wall of the main box 2, the touch switch 37 corresponds to the top wall of the installation box 10, the touch switch 37 is electrically controlled and connected to the drive motor 41, a closing button is provided on the side wall opposite to the limit plate 7, the closing button is electrically controlled and connected to the drive motor 41, and the closing button corresponds to the connecting rack 8.

[0042] Embodiment 4, this embodiment is based on the previous embodiment, such as Figure 1-Figure 11 As shown, a baffle 39 is symmetrically fixedly provided on the circumferential outer wall of the rotating disk 30 , and a stopper 40 is fixedly provided on the circumferential inner wall of the airflow cover 29 , and the stopper 40 corresponds to the baffle 39 .

[0043] When in use, due to the tension of the tension spring 43 on the installation box 10, the initial state of the installation box 10 is above the filter barrel 4, and then the fruit vinegar is poured into the filter barrel 4 through the opening 17, and then the air pump 11 is positively activated. At this time, the outside air is sucked into the airflow conversion cylinder 20 through the external air intake port 22, and then enters the L-shaped connecting pipe 19 and the installation box 10 through the internal air blowing port 24. In this process, due to the reduction of the internal air pressure of the airflow conversion cylinder 20, the L-shaped connecting pipe 19 will move deeper into the airflow conversion cylinder 20. When the bottom plate 38 contacts the installation horizontal plate 35, the internal air blowing port 24 is blocked by the installation horizontal plate 35, and the rubber pad 26 also blocks the opening 17. At this time, the external air intake port 22 corresponds to the position of the internal air intake port 21, and the external air flow enters the L-shaped connecting pipe 19 through the air intake port and finally flows into the installation box 10;

[0044] The air pump 11 introduces the air flow in the installation box 10 into the screen frame 12 through the air holes 25 and the opening 17, thereby improving the filtering efficiency;

[0045] Then the reciprocating motor 15 is started, and the reciprocating motor 15 drives the driving gear 14 and the driven gear 13 to reciprocate, and the driven gear 13 further drives the feed pipe 42 and the screen frame 12 to rotate, and the fruit vinegar on the residue is thrown out by the swinging method, and discharged from the second opening 18 into the receiving tray 28;

[0046] After the filtration is completed, the air pump 11 is activated in reverse to realize the reverse circulation of the air flow. At this time, the external air enters the filter barrel 4 from the opening 2 18, passes through the sieve holes of the sieve frame 12, and then enters the installation box 10 from the opening 17 and the air hole 25. The air flow in the installation box 10 enters the L-shaped connecting pipe 19. At this time, the air pressure in the air flow conversion cylinder 20 increases, and the L-shaped connecting pipe 19 moves upward accordingly. In this process, a part of the air flow in the L-shaped connecting pipe 19 is discharged through the external air suction port 22, and the other part enters the air flow transmission pipe 31 through the external air blowing port 23, and then flows into the air flow cover 29, and finally discharged from the air outlet 33. At this time, the air flow blades 27 are blown by the air flow, thereby driving the rotating disk 30 and the receiving disk 28 to rotate. When the rotating disk 30 rotates 180°, the baffle 39 contacts the block 40 on the other side to limit the rotating disk 30, ensuring that the unloading position of the receiving disk 28 is accurate and correct;

[0047] By designing a method of discharging part of the airflow from the external air inlet 22, it is effectively prevented that the rotating disc 30 rotates too fast and causes the material inside the receiving disc 28 to be thrown out, and it is also prevented that the receiving disc 28 and the rotating disc 30 rotate too fast and slide against each other, thereby ensuring the accuracy of the rotation angle of the receiving disc 28 and the accuracy of the material discharge position;

[0048] When the installation box 10 rises and touches the touch switch, the touch switch activates the drive motor 41, and the drive motor 41 drives the connecting shaft 5, the connecting gear 6 and the filter barrel 4 to rotate, and the connecting gear 6 drives the connecting rack 8 to move to one side. When the connecting rack 8 contacts the closing button, the closing button turns off the drive motor 41, and the filter barrel 4 rotates 180°. The solid residue in the filter barrel 4 will fall into the receiving tray 28. The reciprocating rotation inertia of the reciprocating motor 15 can be used to completely separate the solid residue from the inner wall of the screen frame 12 to prevent the residue from adhering, thereby ensuring that the solid residue can be completely discharged from the screen frame 12; similarly, by using the air pump 11 to pressurize, the air hole 25 and the opening 18 are used as the transmission channel of the airflow, which can improve the efficiency of the discharge of the solid residue. After the filtration is completed, the receiving tray 28 can be taken out using the handle 34.

[0049] In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creatively designing without departing from the purpose of the invention, they should all fall within the scope of protection of the invention.
