Description

Technical Field

[0001] The utility model relates to the technical field of material flow distribution, and particularly relates to a material flow distribution device for a feed chute of a V-type powder separator. Background Art

[0002] In the cement industry, the powder selection process is a crucial link. The change of powder selection efficiency will directly affect the output and power consumption of the entire production system. Among them, the V-type powder separator is one of the most commonly used devices in the powder selection link. It has a simple structure and no transmission parts inside. By controlling the gas flow rate entering the V-type powder separator, the particle size of the separated powder can be adjusted. At the same time, the drying effect of the material can be achieved by controlling the gas temperature. The sorting and drying efficiency of the V-type powder separator is closely related to the uniformity of the material flow inside. Therefore, optimizing the material flow distribution ability of the feed chute of the V-type powder separator is of great significance for improving the efficiency of the powder selection system.

[0003] In the circulating sorting system, when the material entering the V-type powder separator is poorly distributed and there is material deviation, the qualified powder cannot be selected in time, resulting in an increase in energy consumption during the circulation process and a significant reduction in the powder selection efficiency of the V-type powder separator. At present, in the cement production process, the phenomenon of uneven feeding of the V-type powder separator has attracted the attention of industry personnel, but an efficient and convenient method to solve this problem has not been found yet.

[0004] In order to improve the material flow distribution in the V-type powder separator, industry personnel have proposed some improved design schemes. The most commonly used method now is to select a feed chute with multiple parts and multiple strands. The use of this chute has optimized the material flow state entering the V-type powder separator to a certain extent. However, considering the current actual situation and production experience, the optimization effect is not very ideal, and the phenomenon of uneven material flow still occurs from time to time. The reason is that this method ignores the change characteristics of the material flow and lacks the ability of independent adjustment. When the material flow state changes significantly, the phenomenon of uneven material flow will appear again. Therefore, the current feed chute does not have the ability of dynamic material flow adjustment and cannot improve the efficiency of the powder selection system. Summary of the Utility Model

[0005] The utility model aims to provide a material flow distribution device for a feed chute of a V-type powder separator to solve the problems in the prior art that the feed chute does not have the ability of dynamic material flow adjustment, the material distribution is uneven, the material distribution effect is poor, it is easy to cause a short circuit of the powder selection air flow, the sorting efficiency is significantly reduced, the energy consumption of the powder selection system is high, the drying effect of the material to be dried is poor, and the product quality is affected.

[0039] Embodiment

[0040] See Figure 1 、 Figure 2 and Figure 3, in this embodiment, a material flow uniform distribution device for the feed chute of a V-type powder separator is proposed, including a feed chute 1;

[0041] One end of the feed chute 1 has a feed inlet 2, and the other end of the feed chute 1 has a discharge outlet 3.

The plurality of adjusting members 5 are perpendicular to the material flow direction, and one end of the plurality of adjusting members 5 is slidably inserted into the feed chute 1 and abuts against the inner bottom surface inside the feed chute 1.

[0043] During use, when the material enters the feed chute 1 of the V-type powder separator from the feed inlet 2 through the elevator, it will fall on the upper part of the feed chute 1 and form a material flow. At this time, the distribution of the material in the middle part of the feed chute 1 can be viewed through the observation door 4. When it is observed that the material in the middle part of the feed chute 1 is not evenly distributed, the size and state of the material flow are regulated by adjusting the insertion depth of the plurality of adjusting members 5, and the evenly distributed material flow will enter the V-type powder separator through the discharge outlet 3 at the lower part of the feed chute 1.

[0044] A material flow uniform distribution device for the feed chute of a V-type powder separator disclosed in this embodiment has a plurality of observation doors 4 and a plurality of adjusting members 5. The situation can be directly viewed through the plurality of observation doors 4, and the dynamic distribution of the material entering the V-type powder separator can be controlled at any time through the plurality of adjusting members 5. Furthermore, a material flow uniform distribution device for the feed chute 1 of a V-type powder separator has the beneficial effects of simple installation, convenient maintenance, simple operation, having the ability to dynamically adjust the material flow, uniform material distribution, good material uniform distribution effect, not easily causing short-circuit of the powder separation air flow, significantly improving the separation efficiency, low energy consumption of the powder separation system, good drying effect for the material to be dried, and high product quality.

[0045] See Figure 1 , Figure 2 and Figure 3 , the plurality of observation doors 4 have a first observation port 6, a second observation port 7, a third observation port 8, and a fourth observation port 9. The first observation port 6, the second observation port 7, the third observation port 8, and the fourth observation port 9 are opened on a section of the feed chute 1 near the feed inlet 2 at intervals and in parallel. The first observation port 6, the second observation port 7, the third observation port 8, and the fourth observation port 9 are directly opened on the original feed chute 1, making the operation process simple and the transformation cost low.

[0046] On the outer sides of the first observation port 6, the second observation port 7, the third observation port 8, and the fourth observation port 9, there are respectively provided with a first observation door 10, a second observation door 11, a third observation door 12, and a fourth observation door 13. The first observation door 10, the second observation door 11, the third observation door 12, and the fourth observation door 13 are respectively detachably connected to the first observation port 6, the second observation port 7, the third observation port 8, and the fourth observation port 9. Through the first observation door 10, the second observation door 11, the third observation door 12, and the fourth observation door 13, the staff can observe the size and state of the material flow inside the feed chute 1, which is conducive to the staff controlling the material flow inside the feed chute 1 so that the materials can all maintain a uniformly distributed state.

[0047] The first observation door 10, the second observation door 11, the third observation door 12, and the fourth observation door 13 are all made of transparent materials. Using transparent materials facilitates the staff to see the material flow situation inside the feed chute 1 through the first observation door 10, the second observation door 11, the third observation door 12, and the fourth observation door 13, which is convenient for the staff to make corresponding judgments.

[0048] There are several screws 14 at the edges of the first observation door 10, the second observation door 11, the third observation door 12, and the fourth observation door 13. The first observation door 10, the second observation door 11, the third observation door 12, and the fourth observation door 13 are respectively connected to the outer sides of the first observation port 6, the second observation port 7, the third observation port 8, and the fourth observation port 9 through several screws 14. Fixed by several screws 14, the flexibility of the first observation door 10, the second observation door 11, the third observation door 12, and the fourth observation door 13 is improved, which is convenient for disassembly and assembly and is conducive to maintenance and repair.

[0049] See Figure 1 、 Figure 2 and Figure 3 and

[0050] A number of coaxial through holes 17 are provided on the bottom of the first channel steel 15 and the second channel steel 16, and the number of through holes 17 are evenly distributed along the axial direction of the first channel steel 15 and the second channel steel 16; a rod 18 is slidably connected in each of the number of through holes 17. One end of the rod 18 close to the first channel steel 15 penetrates through the through holes 17 of the first channel steel 15 and the second channel steel 16 and the feeding chute 1 and abuts against the inner bottom surface of the feeding chute 1. By changing the insertion depth of the rods 18 at different positions, the flow rate of the material at different positions in the feeding chute 1 can be controlled, and then the material can be controlled to enter the V-type powder separator in a relatively uniform form, eliminating the phenomenon of uneven feeding.

[0051] A handle 19 is fixedly connected to the end of the rod 18 away from the first channel steel 15. One end of the handle 19 is vertically connected to the end of the rod 18 away from the first channel steel 15. The handle 19 facilitates the operator to control the lifting or insertion of the rod 18, improving the operation efficiency.

[0052] A number of nuts 20 are fixedly connected to the two wings of the first channel steel 15, and the number of nuts 20 are evenly distributed along the groove direction of the first channel steel 15. A screw 21 is threadedly connected in each of the number of nuts 20. One end of the screw 21 close to the first channel steel 15 penetrates through the wing plate of the first channel steel 15 and abuts against the outer wall of the rod 18. When the rod 18 is adjusted to the appropriate height, by rotating the screw 21, the end of the screw 21 close to the wing plate of the first channel steel 15 is tightened against the outer wall of the rod 18, effectively achieving the purpose of locking the rod 18.

[0053] An observation window 22 is provided on the outer wall of a section of the feeding chute 1 close to the discharge port 3. When the number of adjusting members 5 adjusts the size and state of the material flow inside the feeding chute 1, the staff can check the state of the material through the observation window 22 close to the discharge port 3 to verify whether the material flow after adjustment is evenly distributed.

[0054] See Figure 1 、 Figure 2 and Figure 3 , in this embodiment, a number of observation doors 4 and a number of adjusting members 5 are installed in the feeding middle chute area of the V-type powder separator. The flow distribution of the material coming from the upper feeding chute 1 of the V-type powder separator can be directly viewed at the number of observation doors 4, so as to obtain the relevant information of the material immediately. By adjusting the height of the rod 18, the material in the middle feeding chute 1 of the V-type powder separator is evenly distributed, thus avoiding the problem of uneven feeding of the material entering the V-type powder separator. The use of the rod 18 reduces the maintenance cost of the device, and at the same time ensures the simplicity and safety of the operation; the combined use of the number of observation doors 4 and the adjustable number of rods 18 ensures the accuracy and immediacy of the material flow control. While ensuring the even distribution of the material entering the V-type powder separator, it can also cope with various possible working conditions.

[0055] See Figure 1 、Figure 2 and Figure 3 In this embodiment, several observation doors 4 and several adjustable bars 18 are welded on-site by opening holes in the middle of the V-type classifier feed chute 1. The installation position needs to be close to the discharge point of the elevator. The installation direction of this device is perpendicular to the material flow direction to better observe and control the material flow.

[0056] See Figure 1 、 Figure 2 and Figure 3 In this embodiment, when the material passes through the upper part of the V-type classifier feed chute 1, several observation doors 4 can observe the flow rate and distribution state of the initial material flow. The shape and number of several observation doors 4 can be set according to the shape and size of the middle part of the V-type classifier feed chute 1. The number of observation doors 4 should not be too small, and it is necessary to ensure that the overall working state of the middle part of the V-type classifier feed chute 1 can be observed more conveniently.

[0057] See Figure 1 、 Figure 2 and Figure 3 In this embodiment, the adjustable bars 18 are round steel. Each round steel and its fittings are detachable, which is convenient for targeted maintenance and replacement. The size, quantity and distribution of the bars 18 depend on the nature of the material. It is necessary to ensure that the flow of the material can be blocked to a large extent. The length of the bars 18 needs to ensure that it can touch the inner bottom surface inside the feed chute 1. During actual operation, only the insertion depth of the round steel bars 18 needs to be controlled.

[0058] In this embodiment, the adjustable bars 18 and the screw 21 can be separately disassembled and replaced, which is convenient for maintenance and replacement.

[0059] See Figure 1 、 Figure 2 and Figure 3 In this embodiment, by changing the insertion depth of the adjustable bars 18 at different positions, the flow rate of the material at different positions in the feed chute 1 can be controlled, and then the material can enter the V-type classifier in a more uniform form, eliminating the phenomenon of uneven feeding; when there is an obvious change in the flow rate in the chute, the situation can be directly checked through the observation door 4. At the same time, the depth of the bars 18 can be adjusted to control the uniform distribution of the material flow, and problems can be solved in time when they occur.

[0060] See Figure 1 、 Figure 2 and Figure 3 In this embodiment, this device only needs to open holes in the middle of the V-type classifier feed chute 1 and install the adjustable bars 18 and the observation door 4. When maintenance is required, only the damaged bars 18 need to be maintained and replaced. When it is necessary to adjust the distribution of the material in the chute, only the bars 18 at specific parts need to be pulled up or inserted to a certain position, which is safe and easy to operate.

[0061] See Figure 1 、 Figure 2 and Figure 3 In this embodiment, the specific implementation process of the material flow distribution device of the V-type powder separator feeding chute is as follows: After the material enters the feeding port 2 of the V-type powder separator feeding chute 1 from the elevator, it will fall on the upper part of the V-type powder separator feeding chute 1 and form a material flow. At this time, the distribution of the material in the middle part of the V-type powder separator feeding chute 1 can be viewed through the observation door 4. When it is observed that the material in the middle feeding chute 1 is not evenly distributed, the insertion depth of several adjusting members 5 is adjusted to control the size and state of the material flow. For example, when it is observed that the material flow in a certain area in the middle part of the V-type powder separator feeding chute 1 is large, the height of the adjustable bar 18 in this area can be reduced, so as to block the flow of part of the material in this area. The blocked material will be diverted to both sides of the adjustable bar 18, increasing the material flow in the two side areas. When adjusting the height of the adjustable bar 18, the material flow situation in the middle part of the V-type powder separator feeding chute 1 can be viewed through the observation door 4 at the same time, so as to more precisely control the distribution of the material flow. After the material flow passes through the adjustable bar 18, the state of the material can also be viewed through the observation windows 22 provided on the middle and lower parts of the V-type powder separator feeding chute 1 to verify whether the material flow is evenly distributed after adjustment. The evenly distributed material flow will enter the V-type powder separator through the discharge port 3 at the lower part of the feeding chute 1. Compared with the distribution effect before the addition of this device, there will be a significant improvement. At the same time, the separation efficiency can be increased and the energy consumption of the powder separation system can be reduced. When the distribution of the material entering the V-type powder separator feeding chute 1 changes again, only the above process needs to be repeated to make the material distribution reach a uniform state again. Therefore, this device can instantaneously adjust the state of the material flow and can ensure that the material entering the V-type powder separator maintains a uniform distribution state under different working conditions.

[0062] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
