Description

Technical Field

[0001] This utility model relates to the field of soybean residue recycling technology, and more specifically, to a soybean residue recycling device. Background Technology

[0002] Soybean pulp is a byproduct of the production of soy milk or tofu. It is the residue left after soybeans have undergone soaking, grinding, boiling, and filtering. Soybean pulp is rich in dietary fiber, protein, unsaturated fatty acids, and various minerals and vitamins such as calcium, phosphorus, and iron, and has high nutritional value.

[0003] In the process of soybean residue recycling, a belt-type roller filter press is usually used to pre-dehydrate the soybean residue. The upper and lower filter belts gradually approach each other to apply initial pressure to the material. The press roller group is also included. The upper and lower filter belts wrap around the rollers to form an "S" shaped path. When the material passes through the rollers, it is mechanically squeezed and the water is forcibly discharged. Then, it is directly sent into the drying cylinder at the end of the conveyor belt for hot drying.

[0004] However, the soybean residue after being squeezed by the rollers will form a relatively compact cake-like structure. When this compact cake-like soybean residue is subsequently sent into the drying drum for hot drying, the internal moisture is difficult to dissipate quickly, which will greatly prolong the drying time, not only increasing energy consumption but also reducing production efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a soybean residue recycling device. By using a receiving plate and crushing blades installed inside the drying drum, the compacted cake-shaped soybean residue is pre-crushed. When it comes into contact with the stirring section later, the stirring section further breaks up the crushed soybean residue, allowing it to exchange heat quickly while in motion, thus achieving a rapid drying effect.

The upper end is connected to a motor that drives its rotation. The receiving plate has a clearance groove for the rotating shaft to pass through. The rotating shaft is provided with several crushing blades in the inner cavity of the receiving plate. The bottom of the receiving plate has several material leakage holes. The rotating shaft is provided with a stirring part below the receiving plate. The bottom of the drying cylinder is provided with a discharge pipe and a control valve is provided on the discharge pipe. The top of the drying cylinder is also provided with a steam vent. Several heating wires are arranged in a ring on the outer wall of the drying cylinder. The heating wires are covered with a heat insulation shell.

[0008] The present invention is further configured such that: first support rods are symmetrically arranged at the bottom of the drying cylinder, a support sleeve is arranged between the two first support rods, and the lower end of the rotating shaft is rotatably engaged with the support sleeve.

[0009] The present invention is further configured such that: a second support rod is symmetrically arranged at the bottom of the receiving plate, and the other end of the second support rod is fixedly connected to the inner wall of the drying cylinder.

[0010] The present invention is further configured such that: a scraper is provided at the lower end of the rotating shaft, the bottom of the scraper is in contact with the bottom surface of the receiving plate, and the scraper is inclined horizontally downward.

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] Reference Figure 1 A soybean residue recycling device includes a belt roller filter press mechanism (not shown in the figure). This structure is a commonly used device for soybean residue treatment and is a mature existing technology, which will not be described in detail here.

[0022] The conveying end of the belt-type double roller filter press mechanism is equipped with a drying cylinder 1. A feed inlet is opened on one side of the drying cylinder 1, and a feed hopper 2 is fixed on the feed inlet. A receiving plate 3 is fixed on the upper part of the interior of the drying cylinder 1. The cross-section of the receiving plate 3 is trapezoidal, and the inner cavity of the receiving plate 3 is located below the feed inlet. A rotating shaft 4 is rotatably connected at the center of the drying cylinder 1. A motor that drives the rotation of the rotating shaft 4 is connected to the upper end of the rotating shaft 4. A clearance groove is opened on the receiving plate 3 for the rotating shaft 4 to pass through. Several crushing blades 5 are fixed on the rotating shaft 4 in the inner cavity of the receiving plate 3. Several material leakage holes 6 are opened at the bottom of the receiving plate 3. A stirring part is set below the receiving plate 3 on the rotating shaft 4. A discharge pipe 7 is fixed on the bottom of the drying cylinder 1. A control valve 8 is fixedly installed on the discharge pipe 7. A steam vent 9 is also opened on the top of the drying cylinder 1. Several heating wires 10 are fixed in a ring on the outer wall of the drying cylinder 1. An insulation shell 11 is covered on the outside of the heating wires 10.

[0023] Additionally, the stirring section includes a plurality of stirring rods 12, which are evenly distributed along the rotation axis 4, thereby forming a relatively uniform stirring force field within the stirring area.

[0024] The bottom of the drying cylinder 1 is symmetrically fixed with first support rods 13, and a support sleeve 14 is fixed between the two first support rods 13. The lower end of the rotating shaft 4 is rotatably engaged with the support sleeve 14. The first support rods 13 and the support sleeve 14 provide a reliable support structure for the rotating shaft 4, which can effectively ensure the stability of the rotating shaft 4 during high-speed rotation.

[0025] The bottom of the receiving plate 3 is symmetrically fixed with a second support rod 15. The other end of the second support rod 15 is fixedly connected to the inner wall of the drying cylinder 1. The second support rod 15 further provides stable support for the receiving plate 3, so that the receiving plate 3 can maintain a fixed position and not shake or deform under the weight of soybean residue and during the crushing process.

[0026] A scraper 16 is fixedly provided at the lower end of the rotating shaft 4. The bottom of the scraper 16 is in contact with the bottom surface of the receiving plate 3, and the scraper 16 is inclined horizontally downward. The scraper 16 can effectively prevent soybean residue particles from adhering to the bottom surface of the receiving plate 3. At the same time, due to its inclined structure, it exerts a downward squeezing force on the soybean residue, thus effectively preventing the leakage hole 6 from being blocked due to the accumulation of soybean residue.

[0027] A humidity sensor 17 is fixedly installed inside the drying cylinder 1. The humidity sensor 17 is electrically connected to the control valve 8. During the drying process of soybean residue, the humidity sensor 17 monitors the humidity of the soybean residue in the drying cylinder 1 in real time and converts the humidity signal into an electrical signal, which is then transmitted to the control valve 8. When the humidity sensor 17 detects that the humidity of the soybean residue has reached the preset drying completion standard, the control valve 8 automatically opens after receiving the electrical signal, and the dried soybean residue is discharged through the discharge pipe 7. If the humidity has not reached the standard, the control valve 8 remains closed and continues to dry the soybean residue, thus realizing the automated control of the soybean residue drying process.

[0028] Working principle: When using this device, the heating wire 10 is started in advance to heat the inside of the drying cylinder 1, so that the inside of the drying cylinder 1 reaches a suitable drying temperature. After the soybean residue is pre-dehydrated by the belt roller filter mechanism, it enters the inside of the drying cylinder 1 through the feed hopper 2, first falling onto the receiving plate 3, and then converging towards the center under the guidance of the shape of the receiving plate 3, contacting the crushing blades 5. The motor drives the rotating shaft 4 to rotate. During the rotation of the rotating shaft 4, on the one hand, it drives the crushing blades 5 located in the inner cavity of the receiving plate 3 to rotate at high speed, and on the other hand, it crushes the soybean residue. The solid, cake-shaped soybean residue is pre-crushed to loosen its structure. The crushed soybean residue particles can fall into the stirring area below the drying cylinder 1 through several leakage holes 6 at the bottom of the receiving plate 3. In the stirring area, the rotating shaft 4 drives the stirring part to further break up the loose soybean residue, so that it can quickly exchange heat in motion and achieve the effect of rapid drying. The water vapor generated during the drying process is discharged through the exhaust port 9 at the top of the drying cylinder 1. When the soybean residue is dried, the control valve 8 on the discharge pipe 7 is opened to discharge the dried soybean residue.

[0029] The motor and humidity sensor 17 of this invention are both electrically connected to the controller to achieve coordinated operation. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0030] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
