[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0027] See also Figure 1-Figure 2 The utility model is a sour soup raw hydraulic pressing device with a filtering structure, comprising a base 1, a top column 2 is fixedly connected to the upper surface of the base 1, a hydraulic cylinder 3 is fixedly installed on the horizontal plate of the top column 2, the lower end of the telescopic rod of the hydraulic cylinder 3 slides through the lower surface of the horizontal plate of the top column 2, a pressing plate 4 is fixedly installed on the lower end of the telescopic rod of the hydraulic cylinder 3, a pressing cylinder 5 is inlaid on the base 1, the pressing cylinder 5 and the pressing plate 4 are in the same vertical position, and the outer surface of the pressing plate 4 is consistent with the inner wall of the pressing cylinder 5, and a filter screen plate 8 is fixedly installed in the pressing cylinder 5;

[0028] When in use, the sour soup raw materials are poured into the pressing cylinder 5 and finally fall onto the filter screen plate 8. At this time, the hydraulic cylinder 3 is started, and the hydraulic cylinder 3 pushes the pressing plate 4 to move downward and move back and forth up and down in the pressing cylinder 5, so that the raw materials on the filter screen plate 8 can be squeezed. The raw liquid produced by squeezing the raw materials falls along the mesh holes of the filter screen plate 8, and the raw material residue remains on the filter screen plate 8.

[0029] Specifically, a placement groove 6 is opened on the outer surface of the base 1, and the pressing cylinder 5 is connected to the inside of the placement groove 6. A collecting tank 7 is placed on the bottom wall of the placement groove 6. The collecting tank 7 and the pressing cylinder 5 are in the same vertical position, so the squeezed raw liquid can eventually fall into the collecting tank 7.

[0030] Specifically, a movable groove 9 communicating with the interior of the pressing cylinder 5 is provided in the base 1, the bottom wall of the movable groove 9 is flush with the upper surface of the filter screen plate 8, a first arc plate 10 is slidably connected in the movable groove 9, a control chamber 11 communicating with the movable groove 9 is provided in the base 1, the first arc plate 10 can slide on the bottom wall of the control chamber 11, a connecting push rod 12 is fixedly installed on the side surface of the first arc plate 10 facing the control chamber 11, the other end of the connecting push rod 12 extends into the control chamber 11, a connecting groove 13 communicating with the interior of the pressing cylinder 5 is provided in the base 1, the connecting groove 13 and the movable groove 9 are arranged in a mirror image, and the two are connected, the bottom wall of the connecting groove 13 is also flush with the upper surface of the filter screen plate 8, and a waste residue chute 14 extending from the outer surface of the base 1 is provided on the bottom wall of the connecting groove 13;

[0031] When in use, by pushing the connecting push rod 12, the connecting push rod 12 synchronously pushes the first curved plate 10 to move to one side of the connecting groove 13. Since the bottom wall of the movable groove 9 is flush with the upper surface of the filter screen plate 8, and the bottom wall of the connecting groove 13 is also flush with the upper surface of the filter screen plate 8, the first curved plate 10 can slide on the filter screen plate 8, so that the waste residue remaining on the filter screen plate 8 can be pushed to the waste residue chute 14, and these waste residues are discharged from the base 1 along the waste residue chute 14. The above method can be used to clean the waste residue on the filter screen plate 8 in time, and the problem of excessive waste residue remaining on the filter screen plate 8 affecting the permeability of the filter screen plate 8 is avoided as much as possible, further ensuring the filtering effect of the filter screen plate 8, and ensuring the sour soup original liquid squeezing efficiency during long-term use.

[0032] Specifically, a second arc plate 15 is slidably connected in the connecting groove 13. The second arc plate 15 and the first arc plate 10 are both semicircular arc-shaped and are arranged in a mirror image. The first arc plate 10 and the second arc plate 15 are combined into a circular ring after contact, and the inner circle thereof is consistent with the inner wall of the pressing cylinder 5. The second arc plate 15 is arranged in the above manner, so that the second arc plate 15 can form a sealing effect on the connecting groove 13, and try to avoid the situation where the raw materials or the original liquid of the sour soup raw materials are squeezed into the connecting groove 13 during the pressing process, thereby further ensuring the pressing effect of the sour soup raw materials.

[0033] In this embodiment, sealing rubber pads are provided on the outer surfaces of the first curved plate 10 and the second curved plate 15, which increases the sealing between the first curved plate 10 and the second curved plate 15 and the movable groove 9 and the connecting groove 13 respectively, and avoids the problem of sour soup stock liquid seeping out of the pressing cylinder 5 along the gap between the first curved plate 10 and the second curved plate 15 as much as possible.

[0034] Specifically, a contraction cavity 17 is provided in the base 1, a contraction rod 16 is fixedly installed on the surface of the second arc-shaped plate 15 facing the contraction cavity 17, the other end of the contraction rod 16 slides through the contraction cavity 17, one end of the contraction rod 16 located in the contraction cavity 17 is fixedly connected to a limiting slide 18, the limiting slide 18 slides in the contraction cavity 17, and a first spring 19 is fixedly installed between the side surface of the limiting slide 18 facing away from the contraction rod 16 and the inner wall of the contraction cavity 17;

[0035] When the first spring 19 is not squeezed, the first spring 19 will form a thrust on the limiting slide plate 18, so that the initial position of the limiting slide plate 18 is close to the side of the connecting groove 13, and the second curved plate 15 is in contact with the first curved plate 10. When the first curved plate 10 pushes the waste residue on the filter screen plate 10 to the waste residue chute 14, the first curved plate 10 squeezes the second curved plate 15, so that the second curved plate 15 is displaced into the connecting groove 13, so that the second curved plate 15 does not block the waste residue trough 14. At the same time, the retraction rod 16 pushes the limiting slide plate 18 to squeeze the first spring 19, causing the first spring 19 to contract. When the first curved plate 10 contracts into the movable groove 9, the first spring 19 releases the thrust, which can push the second curved plate 15 to the initial position and seal the connecting groove 13 again. This method ensures the stability of the second curved plate 15 during operation. At the same time, the setting of the retraction rod 16 avoids the problem of the second curved plate 15 falling into the waste slag chute 14 when sliding into the connecting groove 13.

[0036] See also Figure 2 and Figure 3A support plate 20 is fixedly connected to the upper surface of the base 1, and a rotating disk 21 is rotatably connected to the side of the support plate 20. A rotating shaft 22 is fixedly connected to the surface of the rotating disk 21 on the side facing away from the support plate 20. The rotating shaft 22 is arranged on a side away from the center of the rotating disk 21. The radius of the rotating disk 21 is greater than the diameter of the inner wall of the pressing cylinder 5. A first rotating plate 23 is rotatably sleeved on the rotating shaft 22. An extrusion rod 25 is hinged on the lower side of the first rotating plate 23. The lower end of the extrusion rod 25 slides into the control chamber 11. A second rotating plate 28 is hinged on the lower end of the extrusion rod 25. The lower side of the second rotating plate 28 is hinged to one end of the connecting push rod 12 located in the control chamber 11. A limiting plate 24 is fixedly connected to the side of the support plate 20. The extrusion rod 25 is slidably sleeved on the limiting plate 24. A connecting plate 26 is fixedly sleeved on the extrusion rod 25. A second spring 27 is fixedly connected between the connecting plate 26 and the upper surface of the limiting plate 24. The second spring 27 is movably sleeved on the outer surface of the extrusion rod 25.

[0037] When the rotating disk 21 rotates clockwise, the rotating shaft 22 is displaced eccentrically, thereby causing the first rotating plate 23 to move downward. The first rotating plate 23 simultaneously pushes the extrusion rod 25 to move downward, and the second spring 27 is forced to contract. At this time, the second rotating plate 28 will also form a thrust on the connecting push rod 12, thereby pushing the first curved plate 10 to move toward one side of the waste residue chute 14. Since the radius length of the rotating disk 21 is greater than the diameter of the inner wall of the pressing cylinder 5, the connecting push rod 12 pushes the first curved plate 10 to move a distance greater than the diameter of the pressing cylinder 5, thereby completely scraping off the waste residue on the filter screen plate 8.

[0038] See also Figure 4 A mounting rod 29 is fixedly connected to the outer surface of the rotating disk 21 facing the pressure plate 4, and a contact rod 30 is hinged at the other end of the mounting rod 29. A torsion spring is arranged between the contact rod 30 and the mounting rod 29, so that the contact rod 30 is initially in a vertical state with the mounting rod 29 under the action of the torsion spring, and one end of the contact rod 30 away from the mounting rod 29 contacts the pressure plate 4, and a baffle 31 is fixedly installed on the upper surface of the contact rod 30, and the other side of the baffle 31 extends to the upper side of the mounting rod 29 and contacts the mounting rod 29;

[0039] When the pressing plate 4 moves downward, the lower surface of the pressing plate 4 contacts the contact rod 30, thereby pushing the contact rod 30 to rotate counterclockwise on the mounting rod 29, and at the same time the torsion spring is deformed. When the pressing plate 4 is no longer in contact with the contact rod 30, the contact rod 30 rotates to the initial position under the pull of the torsion spring. When the raw materials in the pressing cylinder 5 are squeezed, the hydraulic cylinder 3 drives the pressing plate 4 to move upward and out of the pressing cylinder 5. At this time, the upper surface of the pressing plate 4 contacts the contact rod 30. Since the upper surface of the contact rod 30 is installed with a baffle 31, the contact rod 30 is connected to the hydraulic cylinder 31. The contact rod 30 is restricted by the baffle 31 and cannot rotate clockwise, so that the contact rod 30 synchronously drives the rotating disk 21 to rotate clockwise, thereby controlling the first arc plate 10 to scrape off the waste residue on the filter screen plate 8. The above method can automatically control the first arc plate 10 to scrape off the waste residue on the filter screen plate 8 after the sour soup raw liquid is squeezed. No human operation is required. It is based on a mechanical linkage structure with high stability and accuracy, further reducing the operating steps and operation amount of the staff, and improving the efficiency of sour soup raw liquid squeezing.

[0040] Working principle: the sour soup raw material is poured into the pressing cylinder 5 and finally falls onto the filter screen plate 8. Then the hydraulic cylinder 3 is started, and the hydraulic cylinder 3 pushes the pressing plate 4 to move downward, and moves back and forth up and down in the pressing cylinder 5, so that the raw material on the filter screen plate 8 can be squeezed. The raw liquid produced by squeezing the raw material falls along the mesh of the filter screen plate 8, and the raw material residue remains on the filter screen plate 8;

[0041] When the raw materials in the pressing cylinder 5 are squeezed, the hydraulic cylinder 3 drives the pressing plate 4 to move upward and out of the pressing cylinder 5. At this time, the upper surface of the pressing plate 4 contacts the contact rod 30. Since the baffle 31 is installed on the upper surface of the contact rod 30, the contact rod 30 is restricted by the baffle 31 and cannot rotate clockwise, so that the contact rod 30 synchronously drives the rotating disk 21 to rotate clockwise, and the rotating shaft 22 is eccentrically displaced, thereby causing the first rotating plate 23 to move downward. The first rotating plate 23 synchronously pushes the extrusion rod 25 to move downward, and the second spring 27 is forced to contract. At this time, the second rotating plate 28 will also form a thrust on the connecting push rod 12, thereby pushing the first arc plate 10 to move to one side of the waste slag chute 14, so that the waste slag remaining on the filter plate 8 can be pushed to the waste slag chute 14, and these waste slags are discharged out of the base 1 along the waste slag chute 14.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
