Description

Technical Field

[0001] This utility model belongs to the technical field of food processing equipment, and in particular relates to a screw extrusion type soybean residue separation and filtration device. Background Technology

[0002] With the increasing demand for soy products, large-scale soy product manufacturing enterprises are emerging. For these enterprises, efficient and stable soy residue separation equipment is the core to ensure production efficiency and product quality. Screw extrusion soy residue separation and filtration equipment, with its unique working principle, uses screw rotation to extrude and filter soy milk mixtures containing soy residue, and is widely used in the industry.

[0003] However, existing screw extrusion soybean residue separation and filtration equipment is not convenient to vibrate the filter plate at its discharge port during use. As the equipment runs, impurities on the surface of the filter plate and the edges of the filter holes will gradually accumulate, which will not only reduce the speed at which soybean milk passes through the filter plate, but may even clog the filter plate. Utility Model Content

[0004] The purpose of this invention is to provide a screw extrusion type soybean residue separation and filtration device. By setting up an oscillating filtration mechanism, it solves the problem that existing screw extrusion type soybean residue separation and filtration devices are not easy to oscillate at their outlet filter plates during use. As the device is running, impurities on the surface of the filter plate and the edges of the filter holes will gradually accumulate, which will not only reduce the speed at which soybean milk passes through the filter plate, but may even clog the filter plate.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a screw extrusion type soybean residue separation and filtration device, including a base plate, two support frames are fixedly connected to the top of the base plate, and an oscillating filtration mechanism and a screw extrusion mechanism are provided on the base plate and the two support frames;

[0007] The oscillating filtration mechanism includes a discharge hopper disposed between two support frames. A filter plate is slidably connected to the inner wall of the discharge hopper. An oscillating block is fixedly connected to the top of the filter plate. A rotating shaft is rotatably connected to the rear inner wall of the discharge hopper. The front side of the rotating shaft extends into the discharge hopper. A half gear is fixedly connected to the front extension of the rotating shaft. A rack is disposed inside the discharge hopper. The rack meshes with the half gear. The rear side of the rack contacts the discharge hopper. The spiral extrusion mechanism includes a protective shell fixedly connected between the two support frames.

[0008] Furthermore, a second oscillating block is fixedly connected to the bottom of the rack, the bottom of the second oscillating block is in contact with the first oscillating block, and a cylindrical groove is provided on the top of the rack, with a sliding rod slidably connected to the inner wall of the cylindrical groove.

[0009] Furthermore, a fixing block is fixedly connected to the top of the slide rod, the top of the fixing block is fixedly connected to the protective shell, a spring is sleeved on the outer wall of the slide rod, the bottom of the spring is fixedly connected to the rack, and the top of the spring is fixedly connected to the fixing block.

[0010] Furthermore, a motor is fixedly connected to the rear side of the discharge hopper, and the output shaft of the motor is fixedly connected to the rotating shaft via a coupling. Fixing blocks are fixedly connected to the left and right sides of the discharge hopper, and the two fixing blocks are fixedly connected to two support frames on the side away from the discharge hopper, respectively. A discharge pipe is connected to the bottom of the discharge hopper.

[0011] Furthermore, a circular fixing block is fixedly connected to the inner wall of the support frame located on the right side, and a variable diameter filter cylinder is fixedly connected to the left side of the circular fixing block. The outer wall of the variable diameter filter cylinder is fixedly connected to the support frame located on the left side.

[0012] Furthermore, a second rotating shaft passes through the circular fixed block, and a variable diameter helical blade is fixedly connected to the outer wall of the second rotating shaft. A second motor is fixedly connected to the right side of the circular fixed block, and the output shaft of the second motor is fixedly connected to the second rotating shaft via a coupling.

[0013] Furthermore, a slag discharge pipe is connected to the left side of the variable diameter filter cartridge, a feed hopper is fixedly connected to the top of the protective shell, the bottom of the feed hopper penetrates the protective shell, and the bottom extension of the feed hopper is connected to the variable diameter filter cartridge.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up an oscillating filter mechanism, when motor 2 is turned on, motor 1 is turned on. Motor 1 drives the half gear to rotate through shaft 1. The half gear drives the rack meshing with it to rise under the limit of the slide rod. The oscillating block 2 on the rack also rises. At this time, the top of the rack squeezes the spring, causing it to contract and store energy until the toothed area on the half gear leaves the teeth on the cylindrical slide groove. At this time, the rack is no longer acted on by the half gear, so the spring rebounds and releases energy, driving the oscillating block 2 to fall until the oscillating block 2 collides with the oscillating block 1, thereby generating vibration on the filter plate. When the teeth on the half gear contact the rack again, the above process is repeated. This process repeats, thereby generating vibration on the filter plate, allowing the soy milk on the filter plate to pass through the filter plate quickly, and after passing through the discharge hopper, it enters the discharge pipe, where it is collected. This high-frequency oscillation prevents impurities from adhering stably to the surface of the filter plate and the edges of the filter holes, thus avoiding the accumulation of impurities on the filter plate, effectively preventing the filter holes from being blocked, and speeding up the speed at which the soy milk passes through the filter plate.

[0016] 2. By setting up a spiral extrusion mechanism, when the mixture of soybean pulp and soybean milk is first put into the feed hopper, the material will enter the variable diameter filter cylinder through the feed hopper. Then, the second motor is turned on, and the second motor drives the variable diameter spiral blades to rotate through the second shaft, thereby carrying the material from the right side to the left side of the variable diameter filter cylinder. Since the inner wall of the variable diameter filter cylinder gradually decreases from right to left, the variable diameter spiral blades decrease synchronously, but the amount of material transported on the variable diameter spiral blades remains unchanged. Therefore, the material on the variable diameter spiral blades will be squeezed by the inner wall of the variable diameter filter cylinder as it is transported to the left, thereby squeezing out the soybean milk, which flows out through the filter holes on the variable diameter filter cylinder, and then falls into the oscillating filtration mechanism below through the gap at the bottom of the protective shell. The soybean pulp, because it is difficult to pass through the filter cylinder, is continuously transported to the left until it is transported into the slag discharge pipe and discharged. This allows the soybean milk to be continuously squeezed out from the gaps in the soybean pulp, achieving efficient solid-liquid separation, thereby improving the separation efficiency and meeting the processing speed requirements of large-scale production.

The two fixing blocks 2113 are fixedly connected to the two support frames 111 on the side away from the discharge hopper 211. The bottom of the discharge hopper 211 is connected to the discharge pipe 2114. By setting the oscillation filter mechanism 2, high-frequency oscillation can be generated so that impurities on the surface of the filter plate 212 and the edge of the filter hole cannot be stably attached, thereby avoiding the accumulation of impurities on the filter plate 212, effectively preventing the filter hole from being blocked, and speeding up the speed at which the soy milk passes through the filter plate 212.

[0029] The spiral extrusion mechanism 3 includes a protective shell 311 fixedly connected between two support frames 111. A circular fixing block 312 is fixedly connected to the inner wall of the support frame 111 on the right side. A variable diameter filter cylinder 313 is fixedly connected to the left side of the circular fixing block 312. The inner diameter of the variable diameter filter cylinder 313 gradually decreases from left to right. The outer wall of the variable diameter filter cylinder 313 is fixedly connected to the support frame 111 on the left side. A rotating shaft 314 passes through the circular fixing block 312. A variable diameter spiral blade 315 is fixedly connected to the outer wall of the rotating shaft 314. The blade diameter of the variable diameter spiral blade 315 decreases from left to right along with the diameter of the variable diameter filter cylinder 313. A motor 316 is fixedly connected to the right side of the fixed block 312. The output shaft of the motor 316 is fixedly connected to the rotating shaft 314 via a coupling.

By setting a spiral extrusion mechanism 3, soybean milk can be squeezed out of soybean residue. Through the cooperation of the spiral blades and the filter cylinder, continuous solid-liquid separation is achieved, thereby improving the separation efficiency and meeting the processing speed requirements of large-scale production.

[0030] A specific application of this embodiment is as follows: In use, firstly, the mixture of soybean pulp and soy milk is placed into the feed hopper 318. The material enters the variable diameter filter cylinder 313 through the feed hopper 318. Then, the second motor 316 is turned on. The second motor 316 drives the variable diameter spiral blades 315 to rotate via the second shaft 314, thereby carrying the material from the right side to the left side of the variable diameter filter cylinder 313. Since the inner wall of the variable diameter filter cylinder 313 gradually decreases from right to left, the variable diameter spiral blades 315 decrease synchronously. However, the variable diameter... The amount of material transported on the spiral blades 315 remains constant. Therefore, the material on the variable-diameter spiral blades 315 is squeezed by the inner wall of the variable-diameter filter cylinder 313 as it is transported to the left, thus squeezing out the soy milk. It flows out through the filter holes on the variable-diameter filter cylinder 313 and then falls into the lower oscillating filter mechanism 2 through the gap at the bottom of the protective shell 311. The soy residue, because it is difficult to pass through the filter cylinder, is continuously transported to the left until it is transported into the residue discharge pipe 317 and discharged. At the same time, the motor 316 is turned on and the motor is turned on. Motor 2112 drives half gear 215 to rotate via shaft 214. Half gear 215 then drives rack 216, which meshes with it, to rise under the limit of slide rod 219. The oscillating block 217 on rack 216 also rises accordingly. At this time, the top of rack 216 compresses spring 2111, causing it to contract and store energy until the toothed area on half gear 215 leaves the teeth on cylindrical slide groove 218. At this point, rack 216 is no longer acted upon by half gear 215, and spring 211... 1. The rebound releases energy, which drives the second oscillating block 217 to fall through the rack 216 until the second oscillating block 217 collides with the first oscillating block 213, thereby generating vibration on the filter plate 212. When the teeth on the half gear 215 contact the rack 216 again, the above process is repeated. This process repeats, thereby generating vibration on the filter plate 212, causing the soy milk on the filter plate 212 to quickly pass through the filter plate 212, and then through the discharge hopper 211 into the discharge pipe 2114, thus completing the collection of the soy milk through the discharge pipe 2114.
