Abstract
Description
Technical Field
[0001] This utility model relates to the field of protein production line technology, and more specifically, to a device for eliminating foam and a protein production line. Background Technology
[0002] Potato starch juice contains a large amount of protein. To fully utilize this intermediate product in the production process, the potato starch juice is extracted to recover the protein, avoiding direct discharge and environmental pollution. This reduces production costs and is also beneficial for energy conservation and environmental protection.
[0003] However, a large amount of foam is generated during the extraction of potato starch juice and the recovery of protein, which is not conducive to subsequent processing.
[0004] Therefore, it is necessary to install a blower and a gas-liquid separator next to the tank to remove foam. Although the gas-liquid separator and blower can achieve a certain foam removal effect, the simple arrangement of the gas-liquid separator and blower results in limited filtration and removal of foam, and can only filter and remove some of the foam in the protein solution.

[0009] The bracket is mounted on the first guide channel;
[0010] A first grid plate is inclinedly disposed in the first flow channel. The bottom end of the first grid plate is located behind the top end of the first grid plate and fixed to the bottom surface of the first flow channel. The top end of the first grid plate extends out of the first flow channel and is connected to the bracket. The left and right sides of the first grid plate respectively abut against the left and right side walls of the first flow channel. The first grid plate is used to adsorb foam in the liquid.
[0011] The suction pipe is connected in sequence to the fan and the gas-liquid separator. The suction pipe is inserted into the tank. The suction end of the suction pipe is set on the bracket. The suction end of the suction pipe is located in front of the first grid plate and facing the first grid plate. The drain pipe of the gas-liquid separator is connected to the tank.
[0012] Furthermore, the input end of the input tube is vertically inserted into the tank, and the input tube is positioned near the side wall of the tank.
[0013] The device for eliminating foam further includes a second guide channel disposed inside the tank below the input pipe. The inlet end of the second guide channel is higher than its outlet end. The bottom surface between the inlet end and the outlet end of the second guide channel is an arc surface that is concave outward from the tank. The inlet end of the second guide channel is located between the side wall of the tank and the input end of the input pipe. The outlet end of the second guide channel is connected to the rear end of the first guide channel.
[0014] Furthermore, the input end of the input pipe is tangent to the bottom surface of the inlet end of the second guide channel.
[0015] Furthermore, the device for eliminating foam also includes a second mesh plate, which is obliquely disposed in the first guide channel in front of the first mesh plate. The bottom end of the second mesh plate is located behind the top end of the second mesh plate and is fixed to the bottom surface of the first guide channel. The top end of the second mesh plate extends out of the first guide channel and is connected to the bracket. The top end of the second mesh plate is flush with the top end of the first mesh plate. The bottom end of the second mesh plate is spaced apart from the bottom end of the first mesh plate. The left and right sides of the second mesh plate are respectively attached to the left and right side walls of the first guide channel. The mesh density of the second mesh plate is greater than that of the first mesh plate.
[0016] Furthermore, the suction end of the suction pipe is located above the first grid plate and the second grid plate, and the suction end of the suction pipe is simultaneously oriented towards the first grid plate and the second grid plate.
[0017] Furthermore, the gas-liquid separator is a cyclone dust collector.
[0018] Furthermore, the front end of the first guide channel is higher than its rear end.
[0019] Furthermore, a baffle is provided inside the tank, the baffle is located at the drain end of the drain pipe, the top of the baffle is connected to the inner wall of the tank, and the bottom of the baffle is spaced apart from the drain end of the drain pipe.
[0020] Furthermore, a support structure is provided inside the tank, which is used to support the first guide channel.

[0022] The beneficial effects of this utility model include at least the following:
[0023] The inventors of this invention introduce foamy starch wastewater discharged from the input pipe into the suction pipe through a first guide channel. A first grid plate is fixed in the first guide channel using a bracket. The left and right sides of the first grid plate are respectively attached to the left and right side walls of the first guide channel, filtering out the foam in the starch wastewater and adsorbing it onto the surface of the first grid plate. The suction end of the suction pipe is positioned in front of and facing the first grid plate, and the suction end of the suction pipe is fixed by the bracket. Under the suction of the fan, the foam adsorbed at the first grid plate is drawn into the gas-liquid separator through the suction pipe. The gas-liquid separator breaks up the foam, and the starch wastewater is discharged into the tank through the drain pipe, thus improving the suction effect of the suction pipe on the foam. In addition, by positioning the output end of the first guide channel close to the inner wall of the tank and with gaps, the starch wastewater, after flowing through the first guide channel, utilizes the characteristics of liquid adhesion to adhere to the inner wall of the tank after detaching from the first grid plate and flows downward along the inner wall. This avoids the starch wastewater from being affected by gravity and colliding with the inner wall, thus preventing the generation of more foam. Attached Figure Description

[0032] See Figures 1 to 4 This embodiment provides a device for eliminating foam, including:
[0033] Tank 1, with an input pipe 11 inserted at its upper end;
[0034] The first guide channel 21 is horizontally arranged inside the tank body 1, and the input end of the input pipe 11 is arranged above the first guide channel 21. The front end of the first guide channel 21 is spaced apart from the inner wall of the tank body 1.
[0035] The bracket 3 is mounted on the first guide channel 21;
[0036] A first mesh plate 41 is inclinedly disposed in the first flow channel 21. The bottom end of the first mesh plate 41 is located behind the top end of the first mesh plate 41 and fixed to the bottom surface of the first flow channel 21. The top end of the first mesh plate 41 extends out of the first flow channel 21 and is connected to the bracket 3. The left and right sides of the first mesh plate 41 are respectively attached to the left and right side walls inside the first flow channel 21. The first mesh plate 41 is used to adsorb foam in the liquid.
[0037] The suction pipe 5 is connected in sequence to the fan 51 and the gas-liquid separator 52. The suction pipe 5 is inserted into the tank 1. The suction end of the suction pipe 5 is set on the bracket 3. The suction end of the suction pipe 5 is located in front of the first grid plate 41 and facing the first grid plate 41. The drain pipe 53 of the gas-liquid separator 52 is connected to the inside of the tank 1.
[0038] It should be noted that, in this embodiment, the bottom of the tank 1 is provided with a cover structure 13, which is used to prevent the starch deposited at the bottom of the tank 1 from floating upwards. Furthermore, a starch discharge port is provided at the bottom of the cover structure 13. The cover structure 13 ensures effective recovery of the filtered protein.
[0039] Additionally, tank 1 here is used to store protein extraction liquid, which can be any one of potato juice, sweet potato juice, soybean juice, or cassava juice. The protein extraction liquid here is typically starch wastewater, which contains a large amount of starch. The starch in the wastewater precipitates and separates within tank 1. After starch separation, the starch wastewater is discharged from the bottom of the enclosure structure 13 and enters the next purification process.
[0040] Alternatively, the gas-liquid separator 52 can be a cyclone separator, a baffle separator, or a packed separator. The gas-liquid separator 52 can break up foam and separate it into gas and liquid. The exhaust end of the gas-liquid separator 52 can be located at its top, while its drain pipe 53 is located at its bottom. Gas is discharged from the exhaust end of the gas-liquid separator 52, and liquid is discharged from the drain end, which is connected to the drain pipe 53.
[0041] In addition, the surface of the first grid plate 41 here has multiple mesh holes spliced together by strips to form a grid.
[0042] The inventors of this invention discovered that a major reason why existing foam removal equipment cannot effectively remove foam is that during the flow of protein extract into tank 1, the protein extract easily collides with the inner wall of tank 1, generating a large amount of foam. Another reason for poor foam removal is that the suction pipe 5 is too far from the foamy protein liquid, resulting in an unsatisfactory suction effect on the foam.
[0043] To address these two issues, the inventors of this invention use a first guide channel 21 to introduce the foamy starch wastewater discharged from the input pipe 11 into the suction pipe 5. A bracket 3 is used to fix a first mesh plate 41 within the first guide channel 21. The left and right sides of the first mesh plate 41 are respectively attached to the left and right side walls of the first guide channel 21, filtering out the foam in the starch wastewater and adsorbing it onto the surface of the first mesh plate 41. The suction end of the suction pipe 5 is positioned in front of and towards the first mesh plate 41. The bracket 3 also fixes the suction end of the suction pipe 5, allowing the foam adsorbed at the first mesh plate 41 to be drawn into the gas-liquid separator 52 by the suction pipe 51 under the suction of the fan 51. The gas-liquid separator 52 breaks up the foam, and the starch wastewater is then connected to the tank 1 through the drain pipe 53 and recycled back into the tank 1, thus improving the suction effect of the suction pipe 5 on the foam. In addition, by having the output end of the first guide channel 21 close to the inner wall of the tank 1 and spaced apart, the starch wastewater, after flowing through the first guide channel 21, utilizes the characteristics of liquid adhesion to adhere to the inner wall of the tank 1 after detaching from the first grid plate 41 and flows downward along the inner wall, thereby preventing the starch wastewater from being affected by gravity and colliding with the inner wall to generate more foam.
[0044] In this way, through the cooperation of the first guide channel 21, the support 3, the first grid plate 41 and the suction pipe 5 in the tank 1, and the effective use of the blower 51 and the gas-liquid separator 52, the foam filtration and elimination effect in protein liquid recovery is improved.
[0045] Furthermore, the input end of the input pipe 11 is vertically inserted into the tank 1, and the input pipe 11 is disposed near the side wall of the tank 1;
[0046] The device for eliminating foam also includes a second guide channel 22, which is disposed inside the tank 1 below the input pipe 11. The inlet end of the second guide channel 22 is higher than its outlet end. The bottom surface between the inlet end and the outlet end of the second guide channel 22 is an arc surface that is concave outward from the tank 1. The inlet end of the second guide channel 22 is located between the side wall of the tank 1 and the input end of the input pipe 11. The outlet end of the second guide channel 22 is connected to the rear end of the first guide channel 21.
[0047] The bottom surface of the second guide channel 22 is set as an arc surface that is concave outward from the tank body 1, so that the protein liquid input by the input pipe 11 can smoothly contact the arc surface of the second guide channel 22, avoiding the protein liquid from impacting and generating foam during the flow out of the input pipe 11, and the protein liquid is smoothly guided to the first guide channel 21 by the second guide channel 22.
[0048] Furthermore, the input end of the input pipe 11 is tangent to the bottom surface of the inlet end of the second guide channel 22.
[0049] This configuration allows the protein liquid flowing out of the input end of the input pipe 11 to flow along the tangent of the arc surface of the second guide channel 22, making full use of the arc surface of the bottom of the second guide channel 22, improving the buffering effect of the second guide channel 22 on the protein liquid, and minimizing the possibility of foaming after the protein liquid is impacted.
[0050] Furthermore, the device for eliminating foam also includes a second mesh plate 42, which is inclinedly disposed in the first guide channel 21 in front of the first mesh plate 41. The bottom end of the second mesh plate 42 is located behind the top end of the second mesh plate 42 and fixed to the bottom surface of the first guide channel 21. The top end of the second mesh plate 42 extends out of the first guide channel 21 and is connected to the bracket 3. The top end of the second mesh plate 42 is flush with the top end of the first mesh plate 41. The bottom end of the second mesh plate 42 is spaced apart from the bottom end of the first mesh plate 41. The mesh density of the second mesh plate 42 is greater than that of the first mesh plate 41.
[0051] Considering that some large foam particles may adhere to the first mesh plate 41, while smaller foam particles may flow through the gaps in the first mesh plate 41, a second mesh plate 42 is provided in front of the first mesh plate 41. The mesh density of the second mesh plate 42 is greater than that of the first mesh plate 41 to improve foam filtration. Simultaneously, the top of the second mesh plate 42 is flush with the top of the first mesh plate 41, allowing the suction end of the suction pipe 5 to simultaneously draw in foam filtered from both the first and second mesh plates 41, ensuring effective suction.
[0052] Furthermore, the suction end of the suction pipe 5 is located above the first grid plate 41 and the second grid plate 42, and the suction end of the suction pipe 5 is simultaneously oriented towards the first grid plate 41 and the second grid plate 42.
[0053] This configuration improves the suction effect of the suction end of the suction pipe 5 on the foam filtered from the first grid plate 41 and the second grid plate 42, preventing foam accumulation at the first grid plate 41 and the second grid plate 42.
[0054] Furthermore, the gas-liquid separator 52 is a cyclone dust collector.
[0055] Furthermore, the front end of the first guide channel 21 is higher than its rear end.
[0056] With this configuration, and the blocking effect of the side wall of the first guide channel 21, the protein liquid can only flow out from the front end of the first guide channel 21, which slows down the speed at which the protein liquid flows towards the front end of the first guide channel 21, thus preventing the protein liquid from colliding with the side wall of the tank 1 and generating foam again.
[0057] Furthermore, a baffle 12 is provided inside the tank body 1. The baffle 12 is located at the discharge end of the drain pipe 53. The top end of the baffle 12 is connected to the inner wall of the tank body 1, and the bottom end of the baffle 12 is spaced apart from the discharge end of the drain pipe 53.
[0058] The protein solution flows out from the drain pipe 53 and, blocked by the baffle 12, flows along the gap between the bottom end of the baffle 12 and the drain end of the drain pipe 53 to the inner wall of the tank 1. It flows along the inner wall of the tank 1, reducing the flow speed of the protein solution and preventing the protein solution from impacting the liquid at the bottom of the tank 1 and generating foam, thereby reducing the amount of foam generated.
[0059] Furthermore, a support structure is provided inside the tank body 1, which is used to support the first guide channel 21.
[0060] The support components here can be multiple crossbeams 14 fixed to the top of the tank body 1. The first guide channel 21 and the second guide channel 22 can be fixed on the crossbeams 14 for easy installation and fixation.
[0061] In addition, this embodiment also provides a protein production line, including the aforementioned equipment for eliminating foam.
[0062] Since the technical effects achieved by this protein production line are the same as those achieved by the equipment used to eliminate foam, the protein production line will not be explained further.
[0063] Additionally, it should be noted that the bracket 3 in this embodiment may include two vertical tripods and a crossbar. The two tripods may be respectively set on the left and right sides of the first guide channel 21. The two ends of the crossbar are respectively connected to the two tripods. The top ends of the first grid plate 41 and the second grid plate 42 are respectively welded and fixed to the crossbar, or can be detachably connected by bolts.
[0064] The bottom ends of the first grid plate 41 and the second grid plate 42 may not be fixed to the first guide channel 21, or they may be fixed by welding.
[0065] In addition, a vertical bar can be installed in front of the horizontal bar, and a fixing sleeve is installed at the front end of the vertical bar, so that the suction end of the suction pipe 5 can be fitted into the fixing sleeve.
[0066] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
