Description

Technical Field

[0001] The present invention relates to the technical field of screw conveyors, and particularly to an energy-saving starch processing production line. Background Art

[0002] The screw conveyor is one of the core equipment in the starch processing production line. It uses the rotation of the screw blade to convey starch from one process to the next process, playing roles such as material conveying, process connection, and reducing labor intensity, which helps to improve the production efficiency of starch.

[0003] For example, a screw conveyor for modified starch production disclosed in the utility model with the publication number CN216154775U has a transmission rod and a screw fan blade arranged in the transmission pipe, and uses a motor to drive the screw fan blade to rotate for conveying starch; however, in the actual production process, starch is easily attached to the surface of the screw fan blade. As the production continues, the starch residue on the screw blade gradually increases, which will increase the rotational resistance of the screw blade, causing the motor to consume more energy to maintain operation, thereby increasing the power consumption; at the same time, the residual starch may deteriorate after long-term accumulation and mix into the subsequent processed starch products, affecting the quality of the products.

[0004] In order to deal with the starch residue on the screw fan blade, a hammering mechanism is provided on the transmission pipe in the prior art, and the transmission pipe or the screw fan blade is hammered by the hammering mechanism to shake off the starch on the inner wall of the conveyor. However, during the starch conveying process, the transmission pipe contains a large amount of starch materials, and the hammering of the hammering mechanism cannot bring a good shaking-off effect, resulting in waste of resources.

[0051] Next, in combination with the specific embodiments of the present invention, the technical solutions in the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0052] As an important industrial raw material and food raw material, starch has a wide range of applications in many fields such as food, chemical industry, and medicine. With the continuous growth of market demand, the scale of the starch processing industry is expanding day by day. In the process of starch processing, improving production efficiency, reducing production costs, and ensuring product quality have always been the goals pursued by enterprises.

[0053] The processing of starch includes processes such as grinding, separation, and drying. During the production process of starch, a screw conveyor is needed to transport the starch from one process to the next to improve the production efficiency of starch and ensure the quality of starch. However, during the actual production process, starch is prone to adhering to the inner wall of the screw conveyor. As production continues, the residual amount of starch on the inner wall of the screw conveyor gradually increases. This will increase the rotational resistance of the screw blades, causing the motor to consume more energy to maintain operation, thereby increasing the power consumption and resulting in a decrease in the conveying efficiency of the screw conveyor. Moreover, the long-term accumulation of residual starch may also deteriorate and mix into the subsequent processed starch products, which will affect the quality of the products.

[0054] To solve the above-mentioned residue problem, in the prior art, usually a knocking mechanism is added or manual cleaning is adopted to remove the starch on the inner wall of the screw conveyor. The manual cleaning method is time-consuming and laborious. It not only has a high labor intensity and low cleaning efficiency, but also causes the production line to stop frequently, seriously affecting the continuity and efficiency of production. When transporting starch, there is a large amount of starch in the screw conveyor, and the knocking effect of the knocking mechanism on the starch is relatively poor. The knocking mechanism can only quickly shake off the starch on the inner wall of the screw conveyor by hammering the screw conveyor in the later stage of starch transportation. Therefore, the knocking mechanism also needs to be equipped with a corresponding start-stop control device, which will reduce the production efficiency of starch.

[0055] As Figure 1 shown, an energy-saving starch processing production line of the present invention includes an outer cylinder 1, a screw conveyor roller 2, and a hammering mechanism 3, which can hammer the screw conveyor roller 2 in the later stage of starch transportation to shake off the starch on the surface of the screw conveyor roller 2 and the inner wall of the outer cylinder 1, improve the conveying efficiency of starch, and realize the resource-saving utilization.

[0056] Both ends of the outer cylinder 1 are respectively provided with a feed inlet 101 and a discharge outlet 102. As Figure 2 shown, the feed inlet 101 is located at the right end of the top side of the outer cylinder 1, and the discharge outlet 102 is located at the left end of the bottom side of the outer cylinder 1. The screw conveyor roller 2 is rotatably arranged in the outer cylinder 1 and abuts against the inner wall of the outer cylinder 1. When starch material is added into the outer cylinder 1 along the feed inlet 101, by using the rotation of the motor on the screw conveyor roller 2, the starch can be pushed to move leftward, so that the starch falls from the discharge outlet 102 to the next production process.

[0057] The hammering mechanism 3 includes a sliding seat 31, a first spring 32, a top block 33, a second spring 34, and a limiting rod 35. A sliding hole 103 is formed in the circumferential side of the outer cylinder 1. The sliding seat 31 is slidably arranged on the outer cylinder 1 and blocks the sliding hole 103. The top block 33 is slidably arranged on the sliding seat 31. The limiting rod 35 is fixedly arranged at one end of the sliding hole 103 close to the feed port 101. One end of the first spring 32 abuts against one side of the sliding seat 31 close to the discharge port 102, and one end of the second spring 34 abuts against one side of the top block 33 close to the sliding seat 31.

[0058] As Figure 7 shown, when the production line is in the initial state, by the abutment of the first spring 32 against the sliding seat 31, the top block 33 is located at one end of the sliding hole 103 close to the feed port 101, as Figure 8 shown, by the abutment of the second spring 34 against the top block 33, a part of the top block 33 extends into the outer cylinder 1.

[0059] When the production line is in the conveying state, as Figure 2 shown, the motor drives the spiral conveying roller 2 to rotate. The rotating spiral conveying roller 2 abuts against the part of the top block 33 extending into the outer cylinder 1 to the left. Since the top block 33 is slidably connected to the limiting rod 35, therefore, the top block 33 does not slide relative to the sliding seat 31, but slides in the direction close to the discharge port 102. When the top block 33 moves to the end of the sliding hole 103 far from the feed port 101, the top block 33 loses the limitation of the limiting rod 35, and then can slide with the sliding seat 31, so that the top block 33 no longer extends into the outer cylinder 1, but is flush with the inner wall of the outer cylinder 1; as Figure 9 shown, when the top block 33 is flush with the inner wall of the outer cylinder 1, the top block 33 abuts against one end of the limiting rod 35 far from the feed port 101, thus preventing the sliding seat 31 from rebounding.

[0060] As Figure 9 and Figure 10 shown, in the middle and early stages of the starch conveying operation, the amount of starch in the outer cylinder 1 is relatively large, which will exert a pressure on one side of the top block 33 far from the sliding seat 31, so that the top block 33 is always located at the position as Figure 9 shown, so that the top block 33 does not hammer the spiral conveying roller 2. In the later stage of the starch conveying operation, the amount of starch in the outer cylinder 1 is relatively small, and the pressure exerted by the starch on the top block 33 is relatively small or the starch does not exert pressure on the top block 33. Therefore, the top block 33 will rebound under the elastic force of the second spring 34. Cooperating with the abutment of the first spring 32 against the sliding seat 31, the top block 33 slides back to one end of the sliding hole 103 close to the feed port 101, and hammers the spiral conveying roller 2 during the rebounding process. As the spiral conveying roller 2 rotates continuously, the top block 33 also moves reciprocally, so as to continuously hammer the spiral conveying roller 2 to shake off the starch on the spiral conveying roller 2.

[0061] With the above structure, it is possible to make the top block 33 hammer the screw conveyor roller 2 only in the later stage of starch transportation. In the middle and early stages of starch transportation, the top block 33 is held in the sliding hole 103 and will not rebound, so it will not hammer the screw conveyor roller 2. This not only ensures the starch transportation efficiency but also maximizes the hammering benefit of the hammering mechanism 3.

[0062] A chute 301 is formed in the sliding seat 31. One end of the top block 33 is slidably arranged in the chute 301. The axis of the chute 301 is inclined with respect to the axis of the outer cylinder 1. The end of the chute 301 close to the axis of the outer cylinder 1 is closer to the feed port 101 than the end away from the axis of the outer cylinder 1. As Figure 2 、 Figure 4 and Figure 5 shown, when the screw conveyor roller 2 abuts against the right side of the top block 33 and the top block 33 moves to the left end in the sliding hole 103, the screw conveyor roller 2 will directly press the top block 33 into the chute 301, so that the contraction of the top block 33 does not only rely on the pressure of starch on it, avoiding the problem that the top block 33 cannot contract when not under the pressure of starch and ensuring the safe operation of the device.

[0063] As Figure 5 and Figure 6 shown, the chute 301 includes a large-diameter part 3011 and a small-diameter part 3012. The top block 33 includes a bottom plate 331 and a resisting block 332. The large-diameter part 3011 is formed in the sliding seat 31, and the small-diameter part 3012 is formed on the side of the sliding seat 31 close to the axis of the outer cylinder 1. The small-diameter part 3012 is communicated with the large-diameter part 3011, and the inner diameter of the large-diameter part 3011 is larger than that of the small-diameter part 3012. The bottom plate 331 is slidably arranged in the large-diameter part 3011. The second spring 34 is arranged in the large-diameter part 3011 and abuts against the side of the bottom plate 331 away from the axis of the outer cylinder 1. The resisting block 332 is fixedly arranged on the bottom plate 331 and is slidably connected with the limiting rod 35 and the small-diameter part 3012, so that the resisting block 332 can slide relative to the sliding seat 31 without detaching from the sliding seat 31. At the same time, starch will not accumulate between the resisting block 332 and the sliding seat 31 to affect the sliding of the resisting block 332, thus ensuring the telescopic performance of the top block 33.

[0064] As Figure 10 shown, the cross-sections of both the resisting block 332 and the sliding hole 103 are trapezoidal, and both are isosceles trapezoids with a wider top and a narrower bottom. When the resisting block 332 is flush with the inner wall of the outer cylinder 1, the left and right side walls of the resisting block 332 are in contact with the inner wall of the sliding hole 103, thus preventing starch from accumulating between them and affecting the rebound of the resisting block 332.

[0065] The hammering mechanism 3 further includes two baffles 36, a sliding rod 37, a limiting block 38 and a fixing screw 39. As Figure 11As shown, the baffle 36 is fixedly arranged on the outer cylinder 1. Two baffles 36 are parallel and spaced apart. The sliding rod 37 is fixedly arranged between the two baffles 36. There are multiple sliding rods 37, and the multiple sliding rods 37 are parallel and spaced apart. The sliding seat 31 is slidably arranged on the sliding rod 37, and the first spring 32 is sleeved on the sliding rod 37, thus ensuring the sliding stability of the sliding seat 31 and the firm fixation of the first spring 32.

[0066] As Figure 11 and Figure 12 shown, the limit block 38 is slidably arranged on the sliding rod 37 and abuts against one end of the first spring 32 away from the sliding seat 31. The fixing screw 39 is connected to the limit block 38 by thread fit and abuts against the sliding rod 37. When the fixing screw 39 is loosened, the fixing screw 39 does not abut against the sliding rod 37, and the limit block 38 can slide relative to the sliding rod 37, thereby adjusting the initial elastic force of the first spring 32. After the initial elastic force of the first spring 32 is adjusted, tighten the fixing screw 39 to make it abut against the sliding rod 37, and the limit block 38 can be fixed. By adjusting the initial elastic force of the first spring 32, the rebound force of the sliding seat 31 can be adjusted, so that the rebound effect of the sliding seat 31 adapts to different working conditions.

[0067] As Figure 5 shown, both the side of the sliding seat 31 close to the feed port 101 and the side of the sliding seat 31 away from the feed port 101 are inclined with respect to the axis of the outer cylinder 1, that is, the cross-section of the part of the sliding seat 31 located in the sliding hole 103 is an isosceles trapezoid with a thinner upper part and a thicker lower part. When the sliding seat 31 slides left and right in the sliding hole 103, the residual starch in the sliding hole 103 can be shoveled into the outer cylinder 1 as much as possible, reducing the residual amount of starch in the sliding hole 103.

[0068] In the middle and early stages of the starch conveying operation, the upper surface of the starch in the outer cylinder 1 is relatively high, and in the later stage of the starch conveying operation, the upper surface of the starch in the outer cylinder 1 is relatively low; As Figure 1 shown, the top block 33 is located above the inner bottom side of the outer cylinder 1, that is, the hammering mechanism 3 is not located directly below the outer cylinder 1, but on the side of the outer cylinder 1. When the upper surface of the starch in the outer cylinder 1 is below the top block 33, no pressure is applied to the top block 33, and when the upper surface of the starch in the outer cylinder 1 is above the top block 33, pressure is applied to the top block 33. With this structural design, the rapid start of the hammering mechanism 3 can be realized in the later stage of the starch conveying operation, thereby improving the knocking-down effect of the hammering mechanism 3 on the starch.

[0069] The spiral conveying roller 2 includes a rotating shaft 21, a first spiral blade 22 and a second spiral blade 23. The rotating shaft 21 is rotatably arranged in the outer cylinder 1 and is connected to a driving motor. The first spiral blade 22 is coaxially fixed on the rotating shaft 21 and abuts against the inner wall of the outer cylinder 1. The first spiral blade 22 is located on the side of the discharge port 102 close to the feed port 101. The second spiral blade 23 is coaxially fixed on the rotating shaft 21 and abuts against the inner wall of the outer cylinder 1. The second spiral blade 23 is located on the side of the discharge port 102 far from the feed port 101, and the spiral direction of the second spiral blade 23 is opposite to that of the first spiral blade 22. As Figure 2 shown, when the motor drives the rotating shaft 21 to rotate, the starch materials at both ends in the outer cylinder 1 can flow towards the discharge port 102, avoiding the problem of starch accumulation at the end in the outer cylinder 1 and improving the conveying efficiency of starch.

[0070] The length of the sliding hole 103 can determine the component that the top block 33 hits when it rebounds. If the length of the sliding hole 103 is small, such as less than the pitch of the first spiral blade 22, the top block 33 will hit one end of the sliding hole 103 close to the feed port 101 when it rebounds, that is, it will hit the outer cylinder 1 instead of the first spiral blade 22. Only when the length of the sliding hole 103 is large enough so that the moving distance of the top block 33 is greater than or equal to the pitch of the first spiral blade 22, the top block 33 will hit the first spiral blade 22 when it rebounds.

[0071] As Figure 4 shown, the side of the first spiral blade 22 far from the feed port 101 is concave, that is, the side where the first spiral blade 22 pushes the starch is concave. When the first spiral blade 22 pushes the starch to move, it can not only increase the contact area between the first spiral blade 22 and the starch material, provide good support for the movement of the starch, but also reduce the amount of starch material entering between the first spiral blade 22 and the inner wall of the outer cylinder 1 to improve the movement efficiency of the starch.

[0072] The side of the first spiral blade 22 far from the feed port 101 abuts against the inner wall of the outer cylinder 1, and the side of the first spiral blade 22 close to the feed port 101 is spaced from the inner wall of the outer cylinder 1. As Figure 4 shown, that is, the outer periphery of the first spiral blade 22 is an inclined surface, which can make the starch between the first spiral blade 22 and the inner wall of the outer cylinder 1 quickly break away from their abutting positions, avoiding the problem of jamming the first spiral blade 22 due to starch accumulation and ensuring the safe operation of the spiral conveying roller 2.

[0073] The side of the first spiral blade 22 far from the feed port 101 is spaced from the side wall of the rotating shaft 21, and the side of the first spiral blade 22 close to the feed port 101 abuts against the side wall of the rotating shaft 21. As Figure 4As shown, the inner circumference of the first spiral blade 22 is beveled, which can not only allow the starch material between the first spiral blade 22 and the rotating shaft 21 to quickly fall into the outer cylinder 1, but also increase the toughness of the first spiral blade 22 and enhance the vibration effect when the first spiral blade 22 is hammered.

[0074] The working principle of an energy-saving starch processing production line of the present invention is as follows:

[0075] When the starch material is injected into the outer cylinder 1 along the feed inlet 101, the rotation of the spiral conveyor roller 2 can be utilized to push the starch material to move within the outer cylinder 1, so that the starch material is discharged from the discharge outlet 102 and enters the next production process of the starch; at the same time, the rotation of the spiral conveyor roller 2 will also drive the top block 33 to move towards the direction close to the discharge outlet 102. In the first and middle stages of the starch material conveying operation, there is more starch material in the outer cylinder 1, which will exert pressure on the top block 33, causing the top block 33 to slide into the chute 301 and making the top block 33 abut against the end of the limiting rod 35 away from the feed inlet 101, so as to prevent the slide seat 31 from rebounding; while in the later stage of the starch material conveying operation, there is less starch material in the outer cylinder 1. After the top block 33 is subjected to the greater pressure caused by the loss of the starch material, it is ejected from the chute 301 by the second spring 34, enabling the top block 33 to slide with the limiting rod 35. At this time, the slide seat 31 driven by the elastic force of the first spring 32 will drive the top block 33 to move towards the direction close to the feed inlet 101, thereby realizing the rebound of the top block 33 and allowing the top block 33 to hammer the spiral conveyor roller 2 to shake off the starch adhering to the surface of the spiral conveyor roller 2.

[0076] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
