[0002] In the process of making bean curd, a large amount of bean curd residue will be inevitably produced, and the bean curd residue contains a large amount of crude protein and crude fiber, so its nutritional value is still good, and it can be used as feed for livestock and poultry. However, at present, due to its high water content (the water content is often more than 85%), it is easy to ferment and deteriorate at room temperature, so it is necessary to use a bean curd residue filter-pressing device to filter the bean curd residue.
[0003] However, in the use of the existing bean curd residue filter-pressing device, due to the pores in the filter cloth, during the filter-pressing process, part of the bean curd residue enters the pores of the filter cloth, which easily blocks the filter cloth after long-term use, affecting the filter-pressing effect of the bean curd residue, and it is difficult to clean the filter cloth during the filter-pressing process.
[0004] To solve the above problems, a kind of bean curd residue filter-pressing device is disclosed in Chinese utility model patent No. CN202420822854.7, which solves the problem by adding a cam between the gaps of the filter cloth. The cam rotates to hit the filter cloth, thereby cleaning the filter cloth. However, in use, the filter cloth is tensioned on each tensioning roller and driven roller by friction. If the filter cloth is hit frequently by the cam, it is easy to cause the filter cloth to loosen, thereby affecting the transmission effect of the filter cloth. UTILITY MODEL CONTENTS

[0030] As described in the background, the existing filter press device is easy to block the filter cloth when filtering the bean dregs, affecting the subsequent filter pressing effect, and a part of the filter press device is provided with a rotating cam between the filter cloth gaps, which can shake off the blocked bean dregs on the filter cloth by rotating the cam and impacting the filter cloth, but this way is easy to cause the filter cloth to be elongated and deformed, thereby affecting the subsequent transmission.
[0031] Based on the above reasons, in order to solve the above problems, the utility model provides the following technical scheme:
[0032] Embodiment 1,
[0033] Please refer to the accompanying Figure 1 ~ accompanying Figure 4 A kind of bean dregs filter press device, including support 1, be provided with the upper filter cloth 4 and lower filter cloth 5 of cyclic rotation;
[0034] Material hopper 10, is set to the upper side of lower filter cloth 5;
[0035] Two compression rollers 9, are respectively set in upper filter cloth 4 and lower filter cloth 5 and are used to extrude the material on lower filter cloth 5 and be delivered to upper filter cloth 4;
[0036] Discharge hopper 7, is set below lower filter cloth 5;
[0037] Cam 16, rotation is set in filter cloth and keeps the outermost end and filter cloth contact;
[0038] Movable roller 12, is movably set on one end of filter cloth and tension filter cloth, the movable roller 12 reciprocating moves along with the contact and separation of cam 16 and filter cloth.
[0039] In this embodiment, in order to realize the cyclic rotation of filter cloth, and extrude and filter the bean dregs delivered on filter cloth, a plurality of tension rollers 8 are arranged on the support 1, the upper filter cloth 4 and the lower filter cloth 5 are sleeved on the outer end of the tension roller 8, a transmission roller 2 for driving the rotation of the filter cloth is arranged at one end of the filter cloth, the transmission rollers 2 on the upper filter cloth 4 and the lower filter cloth 5 are kept in engagement transmission through the gear 3, and a movable roller 12 for tensioning the filter cloth is movably arranged at the other end of the filter cloth, and the compression roller 9 is arranged on the contact end of the upper filter cloth 4 and the lower filter cloth 5.
[0040] In this embodiment, in order to improve the efficiency and quality of the bean dregs filter pressing, a crushing roller 11 for crushing the material is rotationally arranged in the material hopper 10, the crushing roller 11 can be configured as a spiral shaft, so as to crush the large pieces of bean dregs, thereby facilitating the extrusion and filtration between the gap between the upper filter cloth 4 and the lower filter cloth 5.
[0041] In this embodiment, to prevent water stains from flowing out randomly, water guide plates 6 are also inclinedly arranged above both sides of the discharge hopper 7, corresponding to the positions of the press-down filter cloth 5.
[0042] In this embodiment, to facilitate the movement of the movable roller, the filter cloth is always kept taut by the movable roller, ensuring the transmission of the filter cloth and preventing it from being stretched and deformed. Please refer to the attached document. Figure 4 The movable roller 12 is supported by a movable support 13, which is slidably mounted on a slide rail 14. The sliding direction of the slide rail 14 is consistent with the feeding direction of the filter cloth. A telescopic rod 15 is provided between the movable support 13 and the side wall of the bracket 1.
[0043] For further details, please refer to the appendix. Figure 5 The telescopic rod 15 includes an inner cylinder and an outer cylinder. One end of the inner cylinder is fixed to the side of the movable support 13, and the other end of the inner cylinder is inserted into the outer cylinder and keeps telescopic. One end of the outer cylinder is fixed to the side wall of the bracket 1. An elastic element is provided inside the inner cylinder and the outer cylinder, and the two ends of the elastic element are respectively fixed to the inner end of the inner cylinder and the outer cylinder.
[0044] In use, the filter press device connects the shafts of the drive roller 2 and cam 16, as well as the crushing roller 11, to an external drive motor and transmission mechanism. This drives the rotation of the cam 16, the crushing roller 11, and the filter cloth. Then, the tofu residue is poured into the hopper 10. Under the crushing action of the crushing roller 11, large pieces of tofu residue are broken and fall onto the lower filter cloth 5 for conveying. When it reaches the position of the pressing roller 9, it contacts and squeezes the upper filter cloth 4, thereby squeezing out the water stains in the tofu residue. The water stains fall through the pores of the filter cloth onto the lower guide plate 6 and flow into the discharge hopper 7. The squeezed tofu residue passes through the gap between the upper filter cloth 4 and the lower filter cloth 5 and is finally discharged from one end of the drive roller 2, completing the filter press process.
[0045] During the continuous filtration process, cam 16 rotates. When the outermost end of cam 16 contacts the filter cloth, it impacts the filter cloth, thus cleaning it. At the same time, cam 16 continues to rotate, squeezing the filter cloth and driving the movable roller 12 to move towards cam 16. The movable support 13 on the movable roller 12 moves on the slide rail 14, thereby squeezing the telescopic rod 15 and protecting the filter cloth from being stretched and deformed. After cam 16 separates from the filter cloth, the elastic element inside the telescopic rod 15 pushes the movable support 13 to move in the opposite direction on the slide rail 14 under the action of elastic force, thereby making the movable roller 12 tighten the filter cloth, so that the filter cloth continues to rotate and the tofu residue is conveyed.
[0046] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
