Description

Technical Field

[0001] This utility model relates to the field of biotechnology, and in particular to an ultrafiltration device for wheat distillers' grains. Background Art

[0002] Ultrafiltration is a membrane separation process that uses a semi-permeable membrane to separate large and small molecules in a solution. In distillers' grains processing, ultrafiltration can be used to remove suspended solids, bacteria, and other unwanted large molecules while retaining valuable nutrients such as proteins and polysaccharides. The treated distillers' grains can then be used as animal feed or for other industrial applications.

[0003] Patent publication number CN206751783U discloses a distiller's grains filter, including a filter with a support plate, a filter screen at the bottom of the support plate, a hook on the outside of the support plate, a pick-and-place rod at the top of the support plate, and a stirring rod inside the support plate. This distiller's grains filter, as designed in this patent, separates distiller's grains and filtrate through the filter screen. After the distiller's grains are poured in, the stirring rod is rotated to disperse the filter residue accumulated on the filter screen. This method only achieves a simple filtration effect and cannot effectively intercept small particles, microorganisms, and some large molecules, making it unsuitable for applications requiring high purity. Utility Model Content

[0004] In order to overcome the shortcomings of existing distillers' grains filters, which use simple filter membranes or filter membranes to filter grains and have difficulty in effectively separating solids and liquids in the grains, this utility model provides a pressurized wheat distillers' grains ultrafiltration treatment device.

[0005] The technical solution is as follows: A wheat distillers' grains ultrafiltration treatment device includes a frame, a mounting frame, and an extrusion plate. The frame serves as the assembly carrier for this device. The mounting frame is located on the upper part of the frame. An electric push rod I is installed on one side of the upper part of the frame, and a guide rod I is fixedly connected to the other side of the upper part of the frame. One end of the extrusion plate is slidably connected to the guide rod I, and the other end of the extrusion plate is connected to the push rod of the electric push rod I. The mounting frame and the extrusion plate are compatible. The device also includes a semi-permeable membrane, detachably installed inside the mounting frame. The semi-permeable membrane is made of a rigid material (such as a ceramic membrane). (or some metal membranes), the semi-permeable membrane can selectively permeate the desired filtrate; a telescopic plate is connected to the bottom of the extrusion plate via a connecting rod; a spring I is disposed on the connecting rod between the extrusion plate and the telescopic plate; a cleaning component is disposed on the frame, the cleaning component is used to clean the semi-permeable membrane in the mounting frame to prevent the semi-permeable membrane from becoming clogged after long-term filtration and reducing the filtration effect. When the semi-permeable membrane in the mounting frame filters the distiller's grains, the extrusion plate and the telescopic plate are driven to move down the guide rod I by the electric push rod I, so that the telescopic plate can elastically squeeze the distiller's grains on the semi-permeable membrane, thereby accelerating the ultrafiltration efficiency of the distiller's grains.

[0006] Preferably, the telescopic plate is provided with a scale plate, and the extrusion plate is provided with a notch corresponding to the scale plate. An indicator rod adapted to the scale plate is provided at the notch of the extrusion plate. When the telescopic plate extrudes the lees on the semi-permeable membrane, it will overcome the elastic force of spring I and bounce upward, and the indicator rod indicates the corresponding pressure on the scale plate, which makes it convenient for the operator to control the electric push rod I to apply appropriate pressure.

[0007] Preferably, the cleaning component includes: an electric push rod II, installed on one side of the frame; a mounting bracket, the upper frame of the frame having an opening, the mounting bracket being slidably installed at the opening on the upper part of the frame via the guide rod II, the mounting bracket being located below the semi-permeable membrane; multiple nozzles, evenly arranged on the surface of the mounting bracket, the nozzles facing upwards towards the bottom surface of the semi-permeable membrane after the mounting bracket is pushed into the frame; and a connecting pipe, installed on one side of the mounting bracket, the connecting pipe connecting to the multiple nozzles. After the mounting bracket is driven into the frame by the electric push rod II, a water pump is used outside the connecting pipe to spray and clean the bottom surface of the semi-permeable membrane through the multiple nozzle boxes.

[0008] Preferably, the frame at the height of the semi-permeable membrane has a slag discharge port, and the slag discharge port is equipped with a shielding component, which includes: a telescopic rod, symmetrically fixed to the upper two side walls of the frame; a baffle, slidably installed at the slag discharge port of the frame via the telescopic rod, with sealing gaskets on the contact surfaces of the baffle and the slag discharge port; a spring II, disposed on the telescopic rod between the baffle and the outer wall of the frame; a handle I, installed on the outer wall of the baffle; and a locking component, which is also provided on the side of the frame where the shielding component is located, for locking the baffle.

[0009] Preferably, the locking component includes: a support plate symmetrically fixed to the side wall of the frame located below the baffle; a wedge block slidably mounted on the support plate via a sliding rod, the top surface of the wedge block being an inclined surface, the wedge block being used to fit and engage with the baffle; a spring III disposed on the sliding rod between the wedge block and the support plate; and a handle II mounted on the wedge block, the handle II being used for convenient operation of the locking component.

[0010] Preferably, a discharge frame is provided below the liquid outlet of the frame. The discharge frame is shaped like a bucket and is located inside the frame. The discharge frame is used to guide the filtrate after ultrafiltration of distiller's grains.

[0011] The beneficial effects of this utility model are: 1. By setting a semi-permeable membrane, this utility model can effectively separate small molecules from large molecules in the liquid, thereby improving the quality of the filtrate. In conjunction with the electric push rod driving the squeezing plate and the telescopic plate to elastically squeeze the lees on the semi-permeable membrane, the filtration speed can be effectively accelerated and the ultrafiltration efficiency can be improved.

[0012] 2. The telescopic plate of this utility model is equipped with a scale plate and an indicator rod for use in conjunction with each other, so as to help operators intuitively monitor and adjust the pressure applied to the lees, thereby optimizing the filtration process. The electric push rod is combined with a spring to realize the mechanized operation of pressure adjustment and cleaning process of the lees.

[0013] 3. This utility model can also ensure good sealing of the device during operation and avoid leakage problems by setting a baffle with a sealing gasket at the slag discharge port and fixing it with a locking component. Attached Figure Description

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example: A wheat distillers' grains ultrafiltration treatment device, such as Figures 1-3As shown, the device includes a frame 1, a mounting frame 5, and a squeezing plate 4. The frame 1 serves as the assembly carrier for this device. The mounting frame 5 is located on the upper part of the frame 1. The electric push rod I2 is mounted on one side of the upper part of the frame 1. The guide rod I3 is fixed to the other side of the upper part of the frame 1. One end of the squeezing plate 4 is slidably connected to the guide rod I3, and the other end of the squeezing plate 4 is connected to the push rod of the electric push rod I2. The mounting frame 5 and the squeezing plate 4 are compatible. The device also includes: a semi-permeable membrane 6, which is detachably installed inside the mounting frame 5. The semi-permeable membrane 6 is made of a rigid material (such as a ceramic membrane or certain metal membranes) and can selectively permeate the desired filtrate; a telescopic plate 7, which is connected to the bottom of the squeezing plate 4 via a connecting rod; a spring I8, which is located on the connecting rod between the squeezing plate 4 and the telescopic plate 7; and a cleaning component. The cleaning component, mounted on the frame 1, is used to clean the semi-permeable membrane 6 within the mounting frame 5, preventing clogging and reduced filtration efficiency after prolonged filtration. When the semi-permeable membrane 6 filters the lees within the mounting frame 5, the electric push rod I2 drives the extrusion plate 4 and the telescopic plate 7 to move downwards on the guide rod I3, allowing the telescopic plate 7 to elastically press the lees onto the semi-permeable membrane 6, thus accelerating the ultrafiltration process. The telescopic plate 7 has a scale plate 9, and the extrusion plate 4 has a notch corresponding to the scale plate 9. An indicator rod 10, adapted to the scale plate 9, is located at the notch of the extrusion plate 4. When the telescopic plate 7 presses the lees onto the semi-permeable membrane 6, it overcomes the elastic force of the spring I8 and springs upwards, indicating the corresponding pressure on the scale plate 9 via the indicator rod 10, facilitating operator control of the electric push rod I2 to apply appropriate pressure.

[0022] like Figure 1 and Figure 4 As shown, the cleaning component includes: an electric push rod II 11, installed on one side of the frame 1; a mounting bracket 13, with an opening on the upper frame of the frame 1, the mounting bracket 13 being slidably installed at the opening on the upper part of the frame 1 via a guide rod II 12, the mounting bracket 13 being located below the semi-permeable membrane 6; multiple nozzles 14, evenly arranged on the surface of the mounting bracket 13, the nozzles 14 facing upwards towards the bottom surface of the semi-permeable membrane 6 after the mounting bracket 13 is pushed into the frame 1; and a connecting pipe 15, installed on one side of the mounting bracket 13, the connecting pipe 15 connecting to the multiple nozzles 14. After the mounting bracket 13 is driven into the frame 1 by the electric push rod II 11, a water pump is used outside the connecting pipe 15 to spray and clean the bottom surface of the semi-permeable membrane 6 through the multiple nozzles 14.

[0023] like Figure 1 , Figure 2 and Figure 5As shown, the frame 1, located at the height of the semi-permeable membrane 6, has a slag discharge port. The slag discharge port is equipped with a shielding component, which includes: a telescopic rod 16 symmetrically fixed to the upper two side walls of the frame 1; a baffle 17 slidably mounted at the slag discharge port of the frame 1 via the telescopic rod 16, with sealing gaskets on the contact surfaces of the baffle 17 and the slag discharge port; a spring II 18 disposed on the telescopic rod 16 between the baffle 17 and the outer wall of the frame 1; a handle I 19 mounted on the outer wall of the baffle 17; and a locking component, which is used to lock the shielding component on the frame 1. A locking element is also provided on the side, which is used to lock the baffle 17. The locking element includes: a support plate 20, which is symmetrically fixed to the side wall of the frame 1 located below the baffle 17; a wedge block 21, which is slidably installed on the support plate 20 via a sliding rod, the top surface of the wedge block 21 being an inclined surface, and the wedge block 21 being used to fit and latch the baffle 17; a spring III 22, which is disposed on the sliding rod between the wedge block 21 and the support plate 20; and a handle II 23, which is installed on the wedge block 21, and the handle II 23 being used for convenient operation of the locking element.

[0024] like Figure 1 and Figure 2 As shown, a discharge frame 24 is provided below the liquid outlet of the frame 1. The discharge frame 24 is shaped like a bucket and is located inside the frame 1. The discharge frame 24 is used to guide the filtrate after ultrafiltration of distiller's grains.

[0025] When using this device for ultrafiltration of wheat distillers grains, first install the semi-permeable membrane 6 into the mounting frame 5, pour the wheat distillers grains to be treated onto the semi-permeable membrane 6 in the mounting frame 5, and then start the electric push rod I2. The push rod of the electric push rod I2 pushes the extrusion plate 4 downward along the guide rod I3. At this time, the telescopic plate 7 connected to the bottom of the extrusion plate 4 by the connecting rod will gradually contact and extrude the distillers grains. As the extrusion plate 4 moves downward, the telescopic plate 7 applies pressure to the distillers grains under the action of the spring I8. The scale plate 9, in conjunction with the indicator rod 10, can help the operator monitor and adjust the appropriate pressure to optimize the filtration effect. Under the continuous downward pressure of the electric push rod I2, the liquid components in the distillers grains are separated through the selective permeation of the semi-permeable membrane 6. Larger solid particles and impurities are trapped on the surface of the semi-permeable membrane 6. The filtrate flows into the discharge frame 24 below after passing through the semi-permeable membrane 6, and is finally discharged from the outlet of the frame 1. It can be further collected or processed. Then, use the handle II23 to compress the spring III downward. 22. Pull the wedge block 21 to release it from locking the baffle 17. Under the elastic force of spring II 18, the baffle 17 slides open from the frame 1, exposing the discharge port for easy cleaning of the lees filtered by the semi-permeable membrane 6. After cleaning the lees, use handle I 19 to push the baffle 17 back to the discharge port. The baffle 17 presses against the wedge block 21, which then springs back upward under the action of spring III 22 and automatically locks the baffle 17. After filtration is complete, it is necessary to... When cleaning the semipermeable membrane 6, the electric push rod II11 is activated. The electric push rod II11 drives the mounting bracket 13 to slide into the machine frame 1 along the guide rod II12. After the mounting bracket 13 is completely slid into the machine frame 1, the nozzle 14 is directed towards the bottom surface of the semipermeable membrane 6. A water pump is connected to the outside through the connecting pipe 15. After the water flow is turned on, multiple nozzles 14 spray cleaning liquid evenly onto the bottom surface of the semipermeable membrane 6 to remove residual impurities and blockages. The wastewater after cleaning is discharged through the discharge frame 24 at the bottom of the machine frame 1.
