Description

Technical Field

[0001] This application relates to the field of powder screening equipment technology, and in particular to a potato starch screening device. Background Technology

[0002] In the process of potato starch production, the crushed particles need to be screened and graded. Existing screening equipment generally has the following defects:

[0003] 1. Poor adaptability due to non-adjustable screening direction: The motor of a traditional vibrating screen is fixed and the vibration direction is singular. When the characteristics of potato starch particles (such as high fine powder content or many coarse particles) change, the vibration direction cannot be dynamically adjusted to optimize the screening trajectory, resulting in fine powder clogging the screen or incomplete screening of coarse particles, requiring frequent changes in equipment parameters.

[0004] 2. Open collection causes dust pollution: Most equipment uses gravity to collect fine powder directly without sealing the screening chamber; potato starch is easily scattered during the screening process, which not only wastes raw materials but also pollutes the working environment and violates food safety production standards.

[0005] 3. Large particle discharge requires interruption of operation: Large-diameter potato starch residue on the screen requires manual cleaning of the hopper after stopping the machine, which makes continuous production impossible; especially in high humidity environments, potato starch is prone to caking and adhering to the screen surface, further reducing equipment utilization. Utility Model Content

[0006] The problem this application aims to solve is that the vibration direction of existing screening equipment is not adjustable, screening dust is scattered, and large particles require shutdown for cleaning.

[0007] To solve the above-mentioned technical problems, this application provides a potato starch screening device, including a frame; a cylinder fixed to the upper part of the frame; a screening assembly including plate seats symmetrically arranged on both sides of the cylinder, a vibrating motor mounted on the plate seats, and a screen placed flat on the top of the cylinder; the plate seats are connected to the cylinder by bolts and the circumferential angle is adjustable to change the vibration direction of the vibrating motor; a starch collection assembly including a hopper located below the cylinder, a pull-out frame located on the side of the hopper, a mesh bag installed in the frame, a shell located below the hopper, an impeller disposed in the shell, and a rotary motor driving the impeller; the rotary motor drives the impeller to create a negative pressure inside the cylinder, and the screened potato starch is collected in the mesh bag through the hopper.

[0008] Because the potato starch screening equipment of this application is designed with screening components, discharge components, and powder collection components, it can not only change the vibration direction by adjusting the circumferential angle of the plate seat to adapt to the screening needs of potato starch of different particle sizes and reduce the probability of screen blockage, but also create negative pressure by driving the impeller with a rotating motor to collect the potato starch through the mesh bag, thereby improving the potato starch recovery rate. Furthermore, it can control the opening and closing of the material channel by the valve plate and combine it with vibration discharge to achieve online cleaning of large particles, improve equipment utilization, and solve the problems of non-adjustable vibration direction, dust emission during screening, and the need to stop the machine for cleaning of large particles in the existing screening equipment.

[0017] This application relates to a potato starch sieving device, such as... Figure 1-7As shown, the potato starch screening equipment mainly consists of several parts: frame 1, cylinder 2, cylinder cover 3, screening components 4, discharge components 5, and starch collection components 6. The frame 1, as the basic support structure of the entire equipment, is welded from high-strength steel to ensure the stability and reliability of the equipment during operation. The cylinder 2 is located in the center of the upper part of the frame 1. It is cylindrical in shape and made of stainless steel, which not only has good corrosion resistance but also ensures that the potato starch is not contaminated during screening. The cylinder cover 3 is bolted to the top of the cylinder 2. This connection method facilitates disassembly and installation, and makes it convenient to clean and maintain the inside of the cylinder 2.

[0018] The screening component 4 is the core part of the equipment, mainly including plate base 41, vibrating motor 42, spring 43, screen 44 and connecting rod 45. The plate base 41 is symmetrically arranged on both sides of the outer side of the cylinder 2. Each plate base 41 has an arc-shaped groove 46 on its upper part. The design of the arc-shaped groove 46 allows the plate base 41 to be connected to the cylinder 2 by bolts. By tightening or loosening the bolts, the circumferential offset angle between the plate base 41 and the cylinder 2 can be changed. In actual operation, the angle of the plate base 41 can be flexibly adjusted according to the characteristics of the potato starch and the screening requirements, thereby changing the vibration direction of the vibrating motor 42 to achieve the best screening effect. For example, when the potato starch particles are fine, the plate base 41 can be adjusted to a certain angle so that the vibration direction is more conducive to the passage of fine particles; when the potato starch particles are coarse, the angle of the plate base 41 can be adjusted to enhance the screening effect on large particles.

[0019] Vibration motor 42 is arranged on the upper part of plate base 41 and connected to plate base 41 by bolts. Vibration motor 42 is the power source of screening component 4. Its vibration frequency and amplitude can be adjusted by the control system. By rotating plate base 41, the vibration direction of vibration motor 42 is adjusted, thereby changing the screening effect on potato starch inside cylinder 2. In practical applications, the vibration of vibration motor 42 can make potato starch jump and roll on screen 44, accelerating the screening process and improving screening efficiency. Springs 43 connected to frame 1 are evenly and spaced along the circumferential direction on the top of cylinder 2. Springs 43 are made of high elasticity material and have good shock absorption and buffering performance. When vibration motor 42 drives cylinder 2 to vibrate, springs 43 can further improve the vibration screening effect. On the one hand, springs 43 can increase the vibration amplitude of cylinder 2, so that potato starch can be screened more fully on screen 44; on the other hand, springs 43 can reduce the impact of vibration on frame 1, reduce equipment noise and vibration, and extend equipment service life.

[0020] The sieve 44 is placed horizontally on top of the cylinder 2, serving to sieve the potato starch. The sieve 44 is typically made of woven stainless steel wire, possessing high strength and wear resistance. The aperture size of the sieve 44 can be selected according to the sieving requirements of the potato starch; common apertures include 0.1mm, 0.2mm, and 0.3mm. In actual use, the potato starch is added to the cylinder 2 through the feeding port at the top of the cylinder cover 3 and falls onto the sieve 44. Fine potato starch particles pass through the sieve 44 and fall, while larger particles remain on the sieve. On the screen 44, the connecting rod 45 is horizontally placed inside the cylinder 2 and connected to the two plate seats 41. In order to better transmit the vibration of the vibrating motor 42 to the screen 44 at the top of the cylinder 2, the connecting rod 45 is set. The junction between the connecting rod 45 and the cylinder 2 is sealed with a dynamic sealing ring, so that the connecting rod 45 can rotate synchronously with the plate seat 41. The dynamic sealing ring is made of elastic materials such as rubber, which has good sealing performance and can prevent potato starch and dust from entering the inside of the cylinder 2 and affecting the normal operation of the equipment.

[0021] The discharge assembly 5 is used to discharge large-diameter potato starch particles that remain on the upper part of the screen 44 after screening. It mainly includes a material channel 51, a valve stem 52, a valve plate 53, a toothed plate 54, and a locking button 55. The material channel 51 is horizontally arranged on the side of the cylinder cover 3 and communicates with the inside of the cylinder cover 3. The material channel 51 is square in shape and made of stainless steel. The inside of the material channel 51 is smooth, which facilitates the flow of potato starch. In practical applications, the material channel 51 plays the role of guiding the discharge of large-diameter potato starch particles. The valve plate 53 is arranged inside the material channel 51 and can be flipped. The valve plate 53 is usually made of stainless steel or aluminum alloy, which has high strength and wear resistance. The size and shape of the valve plate 53 match the material channel 51 and can completely close the material channel 51. The valve stem 52 is arranged outside the material channel 51 and is used to control the flipping of the valve plate 53. One end of the valve stem 52 is connected to the valve plate 53, and the other end can be operated manually. By rotating the valve stem 52, the valve plate 53 can be flipped inside the material channel 51, thereby controlling the opening and closing of the material channel 51.

[0022] A toothed plate 54 is arranged outside the feed channel 51 to indicate the opening and closing degree of the feed channel 51. The toothed plate 54 is engraved with scales. By observing the relative position of the valve stem 52 and the toothed plate 54, the opening and closing degree of the feed channel 51 can be accurately determined. In actual operation, the opening and closing degree of the feed channel 51 can be adjusted according to the discharge of potato starch to achieve the best discharge effect. A locking button 55 is arranged on the upper part of the valve stem 52 and can be tightened. By controlling the tightness of the locking button 55, the position of the valve stem 52 can be fixed, thereby fixing the feed channel. To adjust the opening and closing degree of channel 51, first loosen the locking button 55, rotate the valve rod 52, adjust it to the appropriate position, and then tighten the locking button 55 to fix the valve rod 52. After screening, by controlling the tightness of the locking button 55, and then using the valve rod 52 to drive the valve plate 53 to rotate, the channel 51 can be unblocked. Then, by adjusting the offset angle of the vibrating motor 42, the large-diameter potato starch particles retained on the upper part of the screen 44 are discharged along the channel 51 under the vibration of the vibrating motor 42.

[0023] The starch collecting assembly 6 is used to collect the fine potato starch that passes through the sieve 44. It mainly includes a hopper 61, a frame 62, a mesh bag 63, a shell 64, an impeller 65, and a rotary motor 66. The hopper 61 is located below the cylinder 2 and is connected to the cylinder 2 by bolts. The hopper 61 is funnel-shaped and made of stainless steel. The inside of the hopper 61 is smooth to facilitate the flow of potato starch. The function of the hopper 61 is to collect the potato starch that passes through the sieve 44 and guide it into the mesh bag 63. The frame 62 is removable and arranged on one side of the hopper 61. The frame 62 is made of metal frame and the surface is treated with anti-corrosion. The design of the frame 62 makes it easy to install and remove the mesh bag 63. In actual use, when the mesh bag 63 is full of potato starch, the mesh bag 63 can be removed by pulling out the frame 62 for further processing.

[0024] The mesh bag 63 is installed inside the frame 62 and is detachable. The structure of the mesh bag 63 is the same as the dust collector bag, made of high-strength fiber material, with good air permeability and filtration performance. The mesh bag 63 has a small pore size, which can trap potato starch inside without affecting air passage. In practical applications, the potato starch is collected inside the mesh bag 63 under negative pressure. When the mesh bag 63 is full, it can be removed and replaced with a new mesh bag 63. The shell 64 is located below the hopper 61 and is connected to the hopper 61 by bolts. The shell 64 is cylindrical and made of stainless steel. The interior of the shell 64 is used to install the impeller 65 and the rotary motor 66. The impeller 65 is concentrically arranged inside the shell 64 and is made of high-strength aluminum alloy material, with high strength and wear resistance. The blade shape of the impeller 65 is optimized to effectively extract air from inside the cylinder 2. The rotary motor 66... The rotary motor 66 is located below the housing 64 and connected to the housing 64 by bolts. The output shaft of the rotary motor 66 is keyed to the impeller 65, so that the rotary motor 66 can drive the impeller 65 to rotate. The power and speed of the rotary motor 66 can be selected according to the actual needs of the equipment. When the rotary motor 66 starts, it drives the impeller 65 to rotate, drawing out the air inside the cylinder 2 and creating a negative pressure inside the cylinder 2. After the sieve powder passes through the screen 44, it is collected into the mesh bag 63 under the action of negative pressure. The side of the housing 64 has a channel for air to flow out, so that the air can enter along the top feeding port of the cylinder cover 3 and be discharged through the channel in the upper part of the housing 64. In actual operation, the air enters the cylinder 2 from the feeding port, passes through the screen 44, carries the fine potato starch particles into the hopper 61, and then passes through the mesh bag 63. The potato starch is trapped in the mesh bag 63, and the air is discharged through the channel in the side of the housing 64.

[0025] Working Principle: When using this potato starch sieving equipment, potato starch is first added into the cylinder 2 through the feeding port at the top of the cylinder cover 3. At this time, the rotary motor 66 is started, driving the impeller 65 to rotate, creating a negative pressure inside the cylinder 2. The negative pressure helps to quickly collect the potato starch passing through the screen 44 into the mesh bag 63, improving collection efficiency. Simultaneously, the vibration motor 42 is started, driving the cylinder 2 to vibrate. The vibration of the cylinder 2 causes the potato starch to jump and tumble on the screen 44, accelerating the sieving process. The spring 43 further enhances the vibration sieving effect, increasing the vibration amplitude of the cylinder 2, allowing the potato starch to be more thoroughly sieving. When the potato starch is sieving on the screen 44, fine potato starch particles pass through the screen 44. The starch falls into the hopper 61 and is collected inside the mesh bag 63 under negative pressure, while larger particles remain on the screen 44. After screening, by controlling the tightness of the locking button 55, the valve plate 53 is rotated by the valve rod 52 to make the material channel 51 unobstructed. Then, the offset angle of the vibrating motor 42 is adjusted so that the large-diameter potato starch particles retained on the upper part of the screen 44 are discharged along the material channel 51 under the vibration of the vibrating motor 42. When the mesh bag 63 is full of potato starch, the mesh bag 63 can be taken out by pulling the frame 62. After taking out the mesh bag 63, it can be cleaned or replaced with a new mesh bag 63. Then, the frame 62 is pushed back into one side of the hopper 61 to continue the screening of potato starch.

[0026] When using the device, select a sieve 44 with an appropriate aperture according to the sieving requirements of the potato starch. Place the sieve 44 flat on top of the cylinder 2, ensuring that the sieve 44 fits tightly against the edge of the cylinder 2 to prevent potato starch from leaking from the edge during sieving. Then, use bolts to fix the sieve 44 to the cylinder 2. When fixing, be careful to apply moderate force to ensure that the sieve 44 is secure without damaging it. Place a new mesh bag 63 inside the frame 62, ensuring that the mesh bag 63 is flat and wrinkle-free and completely covers the opening of the frame 62. Then, slowly push the frame 62 into one side of the hopper 61 to ensure that the frame 62 fits tightly against the hopper 61 to prevent potato starch from leaking from the gaps during collection. Connect the power supply to the rotary motor 66 and start the rotary motor 66 to rotate. Motor 66 drives impeller 65 to rotate, gradually creating a negative pressure inside cylinder 2. During startup, closely observe the operation of motor 66 and check for abnormal noise, vibration, or overheating. If any abnormality is found, stop the motor immediately, check the cause of the fault, and repair it. After motor 66 has been running normally for a period of time and a stable negative pressure has formed inside cylinder 2, start vibrating motor 42. Adjust the vibration frequency and amplitude of vibrating motor 42 according to the characteristics of potato starch and screening requirements. At the same time, the angle of plate seat 41 can be adjusted appropriately to change the vibration direction of vibrating motor 42 to achieve the best screening effect. When adjusting the angle of plate seat 41, operate slowly to avoid excessive vibration or damage to the equipment due to excessively rapid angle adjustment.

[0027] The potato starch to be sieved is slowly added into the cylinder 2 through the feeding port at the top of the cylinder cover 3. During the feeding process, the feeding speed should be carefully controlled to avoid adding too much potato starch at once, which could cause the screen 44 to become clogged or result in poor sieving. The feeding amount can be adjusted according to the equipment's processing capacity and the flowability of the potato starch. During the sieving process, the operator should closely observe the equipment's operation and the accumulation of potato starch on the screen 44. If excessive accumulation of potato starch is found on the screen 44, it may indicate that the screen 44 is clogged or the parameters of the vibrating motor 42 are not set correctly. In this case, feeding should be stopped. Check if the screen 44 is clogged. If it is clogged, clean it in time. At the same time, the vibration frequency and amplitude of the vibrating motor 42 can be adjusted appropriately, or the angle of the plate seat 41 can be adjusted to improve the screening effect. In addition, observe the operation of the powder collection component 6 and check the collection of potato starch in the mesh bag 63 to ensure that the potato starch can be collected smoothly into the mesh bag 63. If the collection speed of the mesh bag 63 is too slow or the air is not discharged smoothly, it may be that the impeller 65 is not rotating fast enough or the channel of the housing 64 is blocked. Check the operation status of the rotary motor 66 and whether the channel of the housing 64 is unobstructed.

[0028] When the screening process reaches the predetermined time or when it is determined by observation that the screening is basically complete, prepare for the discharge operation. First, stop feeding, then slowly release the locking button 55 to allow the valve stem 52 to rotate freely. By rotating the valve stem 52, the valve plate 53 is driven to rotate inside the material channel 51, gradually opening the material channel 51. During the rotation of the valve stem 52, refer to the scale on the toothed plate 54 to precisely control the opening and closing degree of the material channel 51. According to the amount of large-diameter potato starch retained on the screen 44, reasonably adjust the opening and closing size of the material channel 51 to avoid the material channel 51 opening and closing too large, causing potato starch to be discharged too quickly, resulting in waste or blockage, or opening and closing too small. To improve discharge efficiency, while opening the material channel 51, adjust the offset angle of the vibrating motor 42 appropriately. By changing the vibration direction of the vibrating motor 42, enhance the vibration effect on the large-diameter potato starch on the screen 44, allowing the large-diameter potato starch to be discharged more smoothly along the material channel 51. When adjusting the offset angle of the vibrating motor 42, closely observe the discharge of potato starch in the material channel 51 and make fine adjustments according to the actual situation. After the large-diameter potato starch on the screen 44 has been basically discharged, slowly rotate the valve rod 52 to close the valve plate 53, and then tighten the locking button 55 to fix the position of the valve rod 52 and the valve plate 53. At this time, the discharge operation is completed.

[0029] When the mesh bag 63 is full of potato starch, it needs to be replaced with a new one. The operator first cuts off the power to the rotary motor 66 to stop the equipment from running. Then, the operator pulls out the frame 62 to remove the mesh bag 63, which is full of potato starch. When removing the mesh bag 63, care should be taken to avoid spilling the potato starch. The new mesh bag 63 is then installed inside the frame 62 according to the previous installation method and pushed back into the hopper 61. While replacing the mesh bag 63, the equipment can be cleaned. The cylinder cover 3 is opened, and tools such as brushes are used to clean the residual potato starch inside the cylinder 2 and on the screen 44 to ensure that the screen 44 is unobstructed and ready for the next screening. At the same time, the potato starch residue in the feed channel 51 and the hopper 61 is cleaned to keep the equipment clean and hygienic. After cleaning, the cylinder cover 3 is closed, and the equipment is ready for the next use.

[0030] In summary, the potato starch screening equipment of this embodiment, through its reasonable structural design, achieves effective screening and collection of potato starch. The plate base 41, vibrating motor 42, spring 43, screen 44, and connecting rod 45 of the screening component 4 work together to flexibly adjust according to the characteristics of potato starch and screening requirements, thereby improving screening efficiency and quality. The material discharge component 5, including the material channel 51, valve stem 52, valve plate 53, toothed plate 54, and locking button 55, can easily discharge large-diameter potato starch particles, ensuring the normal operation of the equipment. The powder collection component 6, including the hopper 61, frame 62, mesh bag 63, shell 64, impeller 65, and rotary motor 66, can effectively collect fine potato starch and facilitate the replacement and cleaning of the mesh bag 63. This equipment has the advantages of simple structure, convenient operation, and good screening effect, which can meet the screening needs in the potato starch production process, improve production efficiency and product quality. In practical applications, this equipment can also be customized and improved according to different production scales and screening requirements, and has broad application prospects.
